Relevant pericardial effusion caused by cytomegalovirus infection in an immunocompetent patient: a case report
Clinical and molecular implications of structural changes to desmosomes and corneodesmosomes
Abstract
Desmosomes provide the main intercellular adhesive properties between epidermal keratinocytes. Their distribution becomes uneven in severe dermatitis, multiple allergies and metabolic wasting syndrome due to desmoglein 1 deficiency and the loss of intercellular adhesion or acantholysis. When keratinocytes differentiate from granular cells into cornified cells, desmosomes are transformed into corneodesmosomes and can provide stronger intercellular adhesion. Degradation of corneodesmosomes is a tightly regulated process involving a number of proteases and their inhibitors. Peripheral corneodesmosomes are protected from proteolytic degradation by the tight junction-related structures around them, and this construction provides the basis for the normal basket weave-like structure of the stratum corneum. In Netherton syndrome, which is caused by an absence of the protease inhibitor lymphoepithelial Kazal-type-related inhibitor, premature degradation of corneodesmosomes occurs due to the overactivation of proteases involved in corneodesmosome degradation. Inflammatory peeling skin disease is caused by the absence of corneodesmosin, a unique component of corneodesmosomes. In this disease, corneodesmosomes are structurally abnormal, and their adhesiveness is compromised, which leads to intercellular splitting between the stratum corneum and stratum granulosum. The better we understand desmosome and corneodesmosome ultrastructure in normal and diseased skin, the clearer the physiological and pathological mechanisms of epidermal integrity become.

Possible role of plasmacytoid dendritic cells in pityriasis lichenoides
Summary
Background
Plasmacytoid dendritic cells (pDCs) and their product, type I interferons (IFNs), have been implicated in the pathogenesis of several skin disorders characterized by an interface dermatitis (ID) pattern, such as lichen planus (LP). A type I IFN signature has previously been documented in pityriasis lichenoides (PL). Although pDCs are known to be the main source and most potent producers of local type I IFNs, their role in PL has not been investigated.
Aim
To investigate the role of pDCs in PL.
Methods
In total, 20 cases of PL and 20 comparable cases of LP were immunohistochemically tested for pDC occurrence and type I IFN production using anti-blood-derived dendritic cell antigen-2 (BDCA2; a specific pDC marker) and anti-myxovirus protein A (anti-MxA) antibodies (indirect marker of pDC activity), respectively. MxA is a well-established surrogate marker for local type 1 IFN production. A semiquantitative scoring system was used.
Results
pDCs were present in all 40 cases with no statistically significant difference between the two groups. MxA expression was intense and diffuse in the majority of PL and LP cases.
Conclusions
pDCs constitute a central component of the inflammatory infiltrate in PL, suggesting that PL shares with the other entities that exhibit an ID a common pDC-driven process through type I IFN production, which ultimately leads to the cytotoxic attack.

Moyamoya tipping point: fatal bilateral MCA territory infarction following cocaine abuse
Description
An adult Caucasian man with a history of polysubstance abuse was found unresponsive by the nursing staff at his rehabilitation centre and intubated by emergency medical services. On examination, he was stuporous, his eyes did not open to stimulation, his pupils were reactive, localised to pain with bilateral upper extremities and demonstrated triple flexion to noxious stimuli in the bilateral lower extremities. Urine toxicology was positive for cocaine metabolites. A CT scan of the head was performed, which showed possible hypodensities in the bilateral temporal lobes. MRI of the brain was performed to further characterise these hypodensities, and it revealed bilateral middle cerebral artery (MCA) infarction and generalised cerebral oedema (figure 1). CT angiogram of the head at this point was performed, which showed narrowing of both MCAs and possible moyamoya pattern on the left (figure 2). This moyamoya-like vascular change was suggested by narrowing of the left MCA and hypervascular lenticulostriate...

Role of modified Eloesser flap in the treatment of bronchopleural fistula caused by pulmonary coccidioidomycosis
Description
Coccidioidomycosis is a fungal infection by the Coccidioides genus and is usually caused by inhalation of the spores. Patients with diabetes are more likely to present with severe lung disease, especially cavitary lesions.1 2 We depict the case of a 47-year-old man with uncontrolled type 2 diabetes mellitus who presented with a right pulmonary lung abscess due to coccidioidomycosis and underwent a right thoracotomy with partial right upper lobe resection. Intraoperatively the pleura was found to be thickened, and the upper lobe had multiple adhesions and was perforated, creating a purulent bronchopleural fistula. He developed recurrent right-sided empyema due to the fistula and an attempt at a second thoracotomy was unsuccessful. After placement of three failed endobronchial valves, he ultimately had a tunnelled pleural catheter placed. Two weeks later the patient began draining frank pus from the site and a modified Eloesser flap...

Vanadium allergy following total knee arthroplasty
Allergic reactions to metals following joint arthroplasty represent a rare and poorly understood phenomenon. Much is still unknown regarding the natural history of this complication, and how it can best be prevented and managed. We present a case of a 68-year-old woman who underwent a left total knee arthroplasty for treatment of osteoarthritis. After an initial uneventful postoperative course, she developed a troublesome erythematous rash both around the incision site and over her trunk. Blood testing revealed no evidence of infection and clinically her prosthesis was functioning well. Skin patch testing revealed positive results for vanadium (+) and palladium (+). Her cutaneous symptoms are currently being managed conservatively and have shown a partial response to topical steroids. Revision surgery remains a long-term treatment option should conservative therapy fail; however, it would require a custom-made prosthesis as no standard tibial component is free from vanadium.

Megaduodenum in a 59-year-old man: a very late postoperative complication after duodenal atresia
Intestinal malformations are common defects of the newborn, treated in experienced centres. Reports on long-term follow-up and associated complications are scarce, possibly leading to misinterpretation of clinical signs and symptoms in adulthood. To prevent treatment errors, it is important that physicians are aware of long-term complications of intestinal malformations.

Stent-assisted coil embolization on down-the-barrel view with spring-shaped microcatheter in patient with M1 ultrawide necked circumferential aneurysm
Herein, we describe a technique for stent-assisted coil embolization with a spring-shaped microcatheter in a patient with an M1 ultrawide-necked circumferential aneurysm in the middle cerebral artery (MCA). A 49-year-old man was referred for treatment of an incidentally detected M1 large-circumference aneurysm on magnetic resonance angiography. Subsequent digital subtraction angiography revealed an 18.2x16.5 mm ultrawide-necked circumferential aneurysm on the distal M1 portion of the left MCA, and we planned stent-assisted coil embolization using a spring-shaped microcatheter. After we deployed the stent, we performed coil embolization under the down-the-barrel view by pulling out the microcatheter little by little. Using this technique, we could fill the coil mass evenly into the aneurysmal sac around the stent. And there were no immediate or delayed complications after the procedure. Stent-assisted coiling using a spring-shaped microcatheter is a useful and safe technique for treating ultrawide-necked circumferential aneurysm or fusiform aneurysms.

Retroperitoneal bile leak after laparoscopic cholecystectomy
Bile duct injury (BDI) is a well-recognised complication of laparoscopic cholecystectomy (LC). Following a BDI, bile usually leaks into the peritoneal space and causes biliary peritonitis. This manifests as non-specific abdominal pain and fever occurring several days after the surgery. It can be managed by laparoscopic washout with or without bile duct repair. We present a rare case of retroperitoneal bile leak post-LC. The mechanism of injury here was likely partial avulsion from excessive traction of the cystic duct during intraoperative cholangiogram. Diagnosing retroperitoneal bile leak can be difficult because it is extremely rare and the presenting symptoms can be similar to an intraperitoneal bile leak. A high index of clinical suspicion is required. In cases of suspected bile leak, any mismatch between the exploratory laparoscopic findings and imaging findings should alert surgeons to consider the rare possibility of a retroperitoneal bile leak.

Continuous subcutaneous levetiracetam in end-of-life care
Seizures constitute a determining aspect in quality of life and are frequently challenging in palliative care—a field where treatment has yet to be standardised. Levetiracetam—a new generation anticonvulsant—has proved efficacy both through oral, as well as intravenous administration in the general population. This case reports on the use of continuous subcutaneous levetiracetam to effectively control seizures in a terminally ill patient without patent oral route.

Unusual skin mass (primary cutaneous mucinous carcinoma)
Primary mucinous carcinoma of the skin is a rare malignant tumour of sweat gland origin. Diagnostic concerns include its deceptively benign appearance in some cases and the difficulty in differentiating it from secondary mucinous carcinoma of skin metastasising from a primary source elsewhere. A case of a 75-year-old man is reported who presented with a slowly growing painless mass near the lateral canthus of the right eye for about 2 years. Clinically, a diagnosis of basal cell carcinoma was made whereas histopathology revealed mucinous carcinoma of the skin. The primary source of the tumour could not be found on detailed physical examination and laboratory investigations. Immunohistochemistry, performed later, was consistent with primary cutaneous mucinous carcinoma.

An adult case with shigellosis-associated encephalopathy
A 45-year-old man was presented at the emergency department with altered neurological status and a 1-day history of diarrhoea and fever. The patient's sexual history revealed multiple male partners. As bacterial meningitis or viral encephalitis was suspected, treatment was started accordingly. Cerebrospinal fluid investigations only showed a slight increase of leucocytes, and microbiological studies remained negative. Stool culture revealed Shigella flexneri, after which Shigella-associated encephalopathy was suspected. The patient recovered quickly with antibiotic treatment. The incidence of Shigella infections in the Western world is rising due to sexual transmission among men who have sex with men. Shigella-induced encephalopathy is a notorious complication among children with a severe form known as the Ekiri syndrome, though rarely seen in adults. This is the second report of encephalopathy in an adult with S. flexneri enteric infection.

Angiodysplastic Sturge Weber syndrome
Description
A 3-year-old boy presented with global developmental delay, abnormal craniofacial growth and left focal seizures since infancy. He was the first child of a non-consanguineous couple with unremarkable perinatal period. Family history was non-contributory. On examination, he had macrocephaly (head circumference 55 cm, >3 z-score), extensive port-wine stain distributed bilaterally over the face and the trunk, cloverleaf-shaped skull with facial distortion (figure 1A), marked gingival hyperplasia with dental malocclusion (figure 1B), bilateral blue sclera with tortuous engorged veins, brisk muscle stretch reflexes, left hemiparesis and bilateral Babinski's sign. The rest of the systemic examination was unremarkable. A clinical diagnosis of angiodysplastic variant of Sturge Weber syndrome (SWS) with extensive bilateral facial and truncal port-wine stain, glaucoma and focal epilepsy was considered. CT of the brain revealed right-sided subcortical tram-track calcification and concordant parenchymal volume loss (figure 1C). MRI of the brain showed right-sided...

Intravitreal bevacizumab for postviral fever retinitis: a novel approach for early resolution of macular oedema
Severe macular oedema causing marked loss of vision is seen in cases of retinitis developing postviral fever. The use of antivascular endothelial growth factor agents for macular oedema and submacular fluid secondary to viral retinitis has not been studied or well established in the past. We report a case series of two patients of postviral retinitis with severe macular oedema resistant to steroid therapy, treated with intravitreal bevacizumab. The patients showed significant symptomatic improvement in the visual acuity. The retinitis lesions resolved slowly and macular oedema regressed. Bevacizumab appears to be a safe and useful agent to manage macular oedema subsequent to postviral retinitis. An early resolution of macular oedema helps in the preservation of visual acuity which left untreated can cause severe visual loss.

Abnormal deep dorsal vein resulting in veno-occlusive erectile dysfunction
A 59-year-old man with a 6-year history of erectile dysfunction presented to the andrology outpatient clinic. Multimodality assessment with ultrasound, MRI venography and fluoroscopic venography demonstrated an aberrant emissary vein arising from the corporal bodies causing venogenic erectile dysfunction. Selective coil embolisation of the collateral vein resulted in an almost immediate and sustained improvement in his erections.

Anterior choroidal artery infarction
Description
A 38-year-old male patient with a history of hypertension presented with left hemiplegia, hemianaesthesia and hemianopia. MRI of the brain showed anterior choroidal artery (AchA) territory infarct (figure 1). MRI brain angiography and 2D echo were normal. Serum fasting lipid profile, sugar levels, thyroid studies, serum homocysteine levels and antinuclear antibody (ANA), double-stranded deoxyribonucleic acid (DsDNA) and antiphospholipid antibody (APLA) were negative. Trans-oesophageal echocardiography and Holter monitoring were normal. Workup for sickle cell anaemia was negative.

Sacral bone cyst treatment resulting in paraplegia
Description
A 50-year-old man with a stage 1 solitary right sacral plasmacytoma complained of a sharp, burning lower back pain with radiation into his right lower extremity which worsened with movement. He had initially undergone localised radiation therapy, but the pain did not resolve. Postradiation CT-guided biopsy showed persistence of malignant plasma cells, and he then underwent seven cycles of VRD (dexamethasone, lenalidomide and bortezomib) chemotherapy. After chemotherapy, an 18-fluorodeoxyglucose-positron emission tomography/CT scan showed a new area of uptake in the right sacral ala near the initial plasmacytoma. A subsequent CT-guided biopsy was non-diagnostic, and repeat imaging at the time of presentation showed no interval growth. The lesion was believed to be a residual cyst with inflammatory changes from radiotherapy. Examination revealed no neurological deficits. The patient's pain was thought to be secondary to the cyst (figure 1) and was not relieved with physical therapy, duloxetine...

Retrospective audit of patients referred for further treatment following Mohs surgery for non-melanoma skin cancer
Abstract
Background/Objectives
To describe the characteristics, subsequent management and outcomes of patients referred for further management following Mohs micrographic surgery (MMS) for basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).
Methods
Retrospective analysis of patients referred to a quaternary cancer centre from 2000 to 2015.
Results
In total, 83 lesions in 82 patients were referred for further management; 52 (62%) were SCC and 80 (96%) were located in the head and neck. Reasons for referral included high-risk disease for consideration for adjuvant radiotherapy (37/83, 45%), inadequate resection (28/83, 34%) or recurrence following previous MMS (15/83, 17%). Fewer than 40% of the 69 referrals received from MMS surgeons included photos or an operative report and diagram.
There was discordance in pathology opinion in 11 (13%) of cases. Histopathology from MMS was reviewed in eight cases and there was discordance with the in-hospital pathology opinion in six of these. In-hospital re-excision was performed in 19 cases and in five of these the pathology report on the paraffin-sectioned re-excised tissue was discordant with prior MMS assessment. Significantly, two cases were associated with a misinterpretation of lymphocytic infiltrate as residual disease in patients with chronic lymphocytic leukaemia (CLL).
Conclusion
This study highlights some of the challenges and limitations of MMS. Early referral for multidisciplinary management is recommended when MMS resection margins are inadequate or uncertain, especially for high-risk SCC. We recommend that referrals be accompanied by histological material, as well as a detailed report with operative photos and diagrams. CLL can pose an intraoperative diagnostic challenge. Discrepancies in the interpretation of MMS slides present an opportunity for improvement, and our findings support the role of ongoing quality assurance programs.

IntroductionTympanometry is currently the most frequently used tool for assessing the status of the middle ear, commonly assessed using a single 226Hz tone. However, the use of the Acoustic Immittance Measures with a wideband stimulus is a promising high-resolution evaluation, especially in individuals known to have middle ear alterations, such as Down syndrome patients.ObjectiveThe aim of this study was to analyze the acoustic absorbance measurements in children with DS.MethodsCross-sectional study, approved by the institution's ethics committee. Data were collected from 30 children, with a mean age of 8.4 years, 15 with Down syndrome (DS-study group) and 15 children with typical development and no hearing complaints (control group). Energy absorbance was measured at frequencies of 226–8000Hz at ambient pressure and at peak pressure as a function of frequency using TITAN equipment. Statistical analysis was performed using the established level of statistical significance of 5%.ResultsWith the 226Hz probe tone, 30 ears of the control group and 22 of the study group exhibited Type A tympanograms, whereas Type B was observed in eight children in the study group. The mean acoustic absorbance ratio of the study group was lower than that of the control group at frequencies centered at 2520Hz (p=0.008) for those with normal tympanometry results, and 226–4000Hz (p<0.03) for those with a Type B tympanometry curve.ConclusionThe low energy absorption in the presence of normal tympanograms in children with DS may suggest middle ear abnormalities.

Melnick–Needles syndrome (MNS) is a rare congenital X-linked dominant skeletal dysplasia, characterized by exophthalmos, a prominent forehead, and mandibular hypoplasia and retrognathism. Dental features may include anodontia, hypodontia, or oligodontia. Increased collagen content, unpredictable collagen synthesis, and abnormal bony architecture have raised concerns regarding bone splitting intraoperatively and bone healing postoperatively. This report describes the cases of two sisters with MNS, who successfully underwent orthognathic surgery consisting of bilateral mandibular ramus osteotomies combined with advancement genioplasty and iliac crest bone grafting, to correct the classical MNS facial deformity of mandibular retrognathia.

The aim of this study was to evaluate the effectiveness and safety of 5% ethanolamine oleate (EO) foam in the treatment of low-flow venous malformations in the head and neck region. Seventeen consecutive patients (six male, 11 female) and 34 low-flow venous malformations were enrolled. The vascular anomalies ranged between 20mm and 80mm in size. The typical clinical indication was a swelling (88.2%) with a purple colour (85.3%); the most frequent location was the tongue (23.5%). Ethanolamine oleate foam was produced via the Tessari method and applied at 10mg per 1cm to the vascular anomalies. This process resulted in the highest clinical healing score in 64.7% of cases, and half of the patients reported a high level of satisfaction (score >9). In the majority of cases (88.2%), the patients reported that the pain immediately postoperative was mild or moderate. There were direct relationships between vascular anomaly size and the volume of EO applied, the number of sessions, and healing (P<0.05). No recurrence was observed during 6 months of follow-up. This case series showed the effectiveness and safety of 5% EO foam for the treatment of venous malformations in the head and neck region.

Facial morphology and growth following surgery for congenital midline cervical cleft patients
Publication date: Available online 17 January 2018

Congenital midline cervical cleft (CMCC) is a rare condition that consists of a cutaneous midline neck lesion with a sinus extending inferiorly towards the sternum. A fibrous band that extends superiorly to the mandible is a consistent feature of the condition. Restriction of growth of the mandible, possibly due to incomplete removal of the band, is the most significant long-term problem. It remains unclear whether early removal of the fibrous band might allow catch-up growth of the mandible. This study utilized non-invasive three-dimensional photographs to objectively evaluate the facial growth of six CMCC patients. The growth of these CMCC patients was compared to the average growth of age- and sex-matched controls from a database of three-dimensional facial photographs of clinically normal subjects. After surgical removal of the fibrous cord, CMCC patients experience growth in the chin at the same rate as in the normal population; no evidence was found for catch-up growth. As a result, individuals with CMCC are likely to require further surgical intervention to correct the residual retrognathia on completion of facial growth. Early excision of the lesion including aggressive resection of the fibrous band is still recommended, as this should optimize the early growth of the mandible in infancy.

The aim of this study was to investigate the occurrence of oral lesions and micronuclei in crack cocaine users. A cross-sectional study was conducted involving 106 crack users and 106 non-users matched for age, sex, and tobacco use. Socio-demographic characteristics, the consumption of psychoactive substances, and the occurrence of fundamental lesions were investigated. Cellular changes in the oral mucosa (karyolysis, karyorrhexis, 'broken egg' events, and micronuclei) were determined by exfoliative cytology for 54 participants in each group. Crack users had a greater occurrence of fundamental lesions (P=0.001). Furthermore, they had higher mean occurrences of micronuclei (17.25 vs. 3.80), karyolysis (12.39 vs. 9.46), and karyorrhexis (30.39 vs. 10.11) (number per 1000 cells) than non-users (all P<0.05). No difference between the groups was found with regard to broken egg events (P>0.05). After controlling for confounding variables, fundamental lesions were 2.02-fold more frequent and micronuclei were 3.54-fold more frequent in crack users. Crack use was found to be associated with clinical and cellular changes in the oral mucosa. These findings can contribute to the planning of health care for individuals who are dependent on street drugs.

The purpose of this systematic review was to evaluate the quantitative histomorphometric outcomes of animal studies investigating statins as a pro-osteogenic agent to enhance the osseointegration of dental implants. Some animal studies have suggested a beneficial action of statins on bone tissue. Electronic and manual literature searches, without date or language restriction, were performed by two independent review authors up to February 2017. Eligibility criteria included animal trials quantitatively analysing the pro-osteogenic effect of statins on dental implants. The quality of the included studies was assessed using the ARRIVE guidelines. The search and selection process yielded 12 studies, published between 2004 and 2015. The experimental animals models used were rats and dogs. The statins used in the studies were simvastatin and fluvastatin, which were administered locally or systemically, or applied to the implant surface. All of the selected studies showed a statistically significant positive effect of statins on bone formation around implants. The mean quality assessment score (ARRIVE) of the studies was 11.5±2.27 out of a possible total of 25 points. The histomorphometric data from available preclinical studies suggest a positive effect of statins on increasing osteogenesis around dental implants.

Author(s): S. Enzinger, H. Bürger, A. Gaggl
The lateral femoral condyle (LFC) flap is a new flap first reported in 2015 for the treatment of osteomyelitis in hand surgery. This paper introduces a technique of osteochondral LFC flap harvest for mandibular condyle reconstruction and reports on the use of this flap in temporomandibular joint reconstruction. For condyle resection, a pre-auricular approach saving the temporal artery and vein is performed. A step osteotomy technique is used for condyle resection. LFC harvesting starts with dissection of the popliteal artery and vein. The superior genicular artery and vein are identified and followed along their periosteal branches. An osteochondral flap according to the condyle defect is harvested from the anterior pole of the knee. The flap is banded according to the defect and fixed to the mandibular neck with three miniscrews. Follow-up computed tomography scans should be performed at 1 week, 6 months, and 1year after surgery. The case of a 58-year-old female patient with osteomyelitis of the left mandibular condyle after multiple preoperative therapies is reported. The LFC flap technique was used for left condyle reconstruction, resulting in good functional and morphological outcomes at the 6-month postoperative follow-up. In conclusion, the osteochondral LFC flap is a new and promising technique for mandibular condyle reconstruction for special indications.

The objective of this study was to assess changes in patient quality of life (QoL) after orthognathic surgery at the Kuwait University Dental Clinic. A self-administered Arabic version of the Orthognathic Quality of Life Questionnaire (OQLQ) and two different visual analogue scales (VAS) were used. Sixty-six patients participated (63.6% female). The deformities were corrected by bimaxillary jaw surgery (83.3%), Le Fort I (9.1%), and bilateral sagittal split osteotomy (7.6%). The most important reasons given for undertaking the surgery were facial aesthetics (80.3%) and bite correction (75.8%). Of the patients who had reported moderate to high levels of problems pre-surgery, the majority reported improvements in facial appearance (91.3%), appearance of the teeth (97.0%), biting (96.3%), chewing (92.3%), and eating function (76.5%). Overall, 93.9% of patients reported better conditions after surgery, and the satisfaction level was very high (VAS 91.6%). The VAS score for QoL increased significantly from pre-surgery (73.0%) to post-surgery (93.6%) (P=0.0001). The OQLQ score was also significantly decreased after surgery, reflecting improvements in the 'social aspects of dentofacial deformity', 'facial aesthetics', 'oral function', and 'awareness of dentofacial aesthetics' domains (P=0.0001). Overall, the patients who underwent orthognathic surgery were satisfied and had improved QoL. The satisfaction rate in the present study reflects successful treatment with orthognathic surgery.

Extracapsular spread (ECS) of metastatic lymph nodes from oral carcinoma is the most significant prognostic predictor of a poor treatment outcome. However, only a few reports on prognostic factors in ECS-positive cases have been investigated. To address this problem, a detailed examination of ECS pathology was conducted to determine the prognostic factors of oral squamous cell carcinoma (OSCC) with ECS of metastatic lymph nodes. This study involved 63 OSCC patients with at least one pathologically metastatic node with ECS. Among the 229 metastatic lymph nodes, 149 exhibited ECS. Univariate analysis revealed that a poor outcome and recurrence were significantly associated with the number of ECS-positive nodes, density of ECS, and the minor axis of the smallest ECS-positive node. However, multivariate analysis identified only small size of ECS-positive nodes as a significant and independent factor predicting recurrence and a poor outcome. Thus, small size of ECS-positive nodes is the most important prognostic indicator for OSCC with ECS in metastatic lymph nodes. The classification of ECS status using the minor axis of ECS-positive nodes may be useful for further prediction of a poorer prognosis in OSCC cases. Standardization of ECS diagnosis and multicenter prospective studies will be required to confirm and refine these findings.

The Development of a Nano-based Approach to Alleviate Cisplatin-Induced Ototoxicity
Abstract
Cisplatin-induced hearing loss is experienced by a high percentage of patients with squamous cell carcinoma undergoing cisplatin chemotherapy. A novel nano-construct capable of sequestering extracellular cisplatin was developed to combat this problem. The nano-construct consisted of superparamagnetic iron oxide nanoparticles (SPIONs) entrapped within polymeric micelles, which were formed from a glutathione diethyl ester-conjugated amphiphilic diblock copolymer. The glutathione-micelles were analyzed at the cellular level and in an organotypic study for safety evaluation. All utilized methods indicated that the micelles do not cause cellular toxicity or organ damage. The micelles' ability to reduce cisplatin-induced cytotoxicity was then probed in an in vitro model. Cisplatin was pre-treated with the novel nano-construct before being added to growing cells. When compared to cells that were exposed to untreated cisplatin, cells in the pre-treated cisplatin group showed a significant increase in cell viability. This clearly demonstrates that the construct is able to protect the cells from cisplatin cytotoxicity and makes it highly likely that the novel nano-construct will be able to play a role in the protection of the inner ear from cisplatin-induced ototoxicity.

Complex issues in new ultrasound-guided nerve blocks: how to name, where to inject, and how to publish
Abstract
The recent development of ultrasound-guide nerve block has led to innovation in anesthesia and pain clinics. However, it has also led to some complex issues, including (1) how to name a new technique, (2) the appropriateness of an intramuscular approach, and (3) how to publicize a new technique. This review addresses naming strategy, feasibility of intramuscular approach block, and methods of publication. First, researchers and authors should pay attention to appropriate nomenclature for the term 'approach', 'compartment block', and 'nerve block' for a new block. Second, it is lack of evidences to facilitate muscle injection, and adequate preparation and adherence to proper technique for intramuscular approach block should be considered; confirmation of abnormal signs at the injection area, use of a thin needle and the lowest concentration and volume of local anesthetic without supplementation with steroid or epinephrine, compressing hemostasis, and sufficient interval of the blocks. Third, adequate dissemination of information would also be necessary through publication in appropriate media. We hope this review boost reasonable development of nerve block.

Therapieoptionen bei Sarkomen an der Wirbelsäule
Zusammenfassung
Hintergrund
Sarkome an der Wirbelsäule stellen aufgrund ihrer Heterogenität, Seltenheit und anatomischen Lage eine große Herausforderung für die Behandelnden dar.
Fragestellung
Diskutiert werden die Behandlungsmöglichkeiten (State-of-the-art).
Material und Methode
Es werden die aktuelle Literatur, Expertenmeinungen und Konsensempfehlungen internationaler Expertengremien diskutiert.
Ergebnisse
Es gibt folgende Konsensus-Empfehlungen: a) Osteosarkom: kombinierte Therapie: neoadjuvante Chemotherapie/En-bloc-Resektion/Strahlenresistenz; b) Ewing-Sarkom: kombinierte Therapie: neo- und adjuvante Chemotherapie/Restaging und Bestimmung des Regressionsgrads vor En-bloc-Resektion zwingend/En-bloc-Resektion und/oder Radiotherapie; c) Chondrosarkom: wenn möglich En-bloc-Resektion. Intensitätsmodulierte Radiotherapie scheint selektiv eine primäre oder adjuvante Option zu sein.
Etablierte Operationsverfahren (En-bloc-Resektion) kombiniert mit neuen Techniken (Implantate, Materialen/3D-Navigation), präziseren Bestrahlungsoptionen (intensitätsmodulierte Photonenbestrahlung) und Anwendung von Partikelstrahlung lassen eine Verbesserung der Therapieergebnisse erwarten.
Schlussfolgerung
Das beste Outcome haben Patienten, welche von Beginn an (bereits zur Biopsie) einem ausgewiesenen Tumorzentrum zugewiesen werden. Das Behandlungskonzept ist immer multidisziplinär.

Congenital aneurysm of both left ventricle and left atrium
Annals of Pediatric Cardiology 2018 11(1):97-99
This is a case of both congenital left ventricular (LV) free wall submitral aneurysm and left atrial appendage aneurysm with 6 years of clinical follow-up. Each lesion is a rare entity, and to the best of our knowledge, this is the first case in medical literature of both lesions occurring in the same patient, raising the likelihood of a common etiology. The workup was initiated in the third trimester of fetal life with irregular heart rate and abnormal fetal ultrasound and echocardiogram at that time. The patient required emergent atrial appendage plication due to blood clot formation and suffered from multiple other complications including ventricular ectopy and surgically induced pseudoaneurysm. Follow-up interval echocardiograms have revealed continued good LV function with persistent LV aneurysm. In review of the case, there were several potential in utero causes including maternal viral upper respiratory infection and bacteriuria with exposure to amoxicillin. These as well as other considerations are discussed along with a brief review of these rare lesions, usual presentation, and known associations.

Arterial duct and pulmonary arteriovenous malformations: A shunt masking a shunt
Annals of Pediatric Cardiology 2018 11(1):89-91
A 5-month-old infant, referred to our institution for percutaneous arterial duct (AD) embolization, showed multiple huge pulmonary arteriovenous malformations (PAVMs) associated with a small AD and several tiny systemic-to-pulmonary collaterals. This anatomic arrangement was a possible cause of lack of cyanosis and disproportionately higher hemodynamic relevance of the ductal shunt. The PAVMs became pathophysiologically evident immediately after the closure of AD and systemic to pulmonary artery collaterals and presented clinically with a life-threatening cyanosis. To improve the patient's clinical and hemodynamic condition, the PAVMs were closed in multiple sittings using a large number of Amplatzer Vascular Plugs (St. Jude Medical Inc., St. Paul, MN, USA). The hemodynamic burden of cardiac malformations resulting in left-to-right shunt may be magnified by the presence of PAVMs as a result of low pulmonary vascular resistance which in turn may completely mask the clinical impact of the latter. Transcatheter approach is life-saving in these complex arrangements.

Extracorporeal membrane oxygenation in pediatric cardiac surgery: A retrospective review of trends and outcomes in Scotland
Annals of Pediatric Cardiology 2018 11(1):3-11
Introduction : Around 3.2%–8.4% of patients receive venoarterial (VA) extracorporeal membrane oxygenation (ECMO) support after pediatric cardiac surgery. The desired outcome is "bridgetorecovery" in most cases. There is no universally agreed protocol, and given the associated costs and complications rates, the decisions as of when and when not to institute VA ECMO are largely empirical. Methods : A retrospective review of the ECMO database at the Scottish Pediatric Cardiac Services (SPCS) was undertaken. Inclusion criterion encompassed all children (<16 years of age) who were supported with VA ECMO following cardiac surgery between January 2011 and October 2016. The timing of ECMO support was divided into three distinct phases: "endofcase" or intheatre ECMO for patients unable to effectively wean from cardiopulmonary bypass (CPB), ECMO for cardiopulmonary resuscitation ("ECPR"), and Intensive Care Unit ECMO for "failing maximal medial therapy" following cardiac surgery. The patients were analyzed to identify survival rates, adverse prognostic indicators, and complication rates. Results : We identified 66 patients who met the inclusion criterion. 30day survival rate was 45% and survival rate to hospital discharge was 44% (the difference represents one patient). On followup (median: 960 days, range: 42–2010 days), all survivors to hospital discharge were alive at review date. "Endofcase" ECMO showed a trend toward better survival of the three subcategories ("end of case," ECPR, and ECMO for "failing maximal medical therapy" survival rates were 47%, 41%, and 37.5%, respectively, P = 0.807). The poorest survival rates were in the younger children (<6 months, P = 0.502), patients who had prolonged CPB (P = 0.314) and aortic crossclamp times (P = 0.146), and longer duration of ECMO (>10 days, P = 0.177). Conclusions : Allcomers VA ECMO following pediatric cardiac surgery had survival to discharge rate of 44%. Elective "endofcase" ECMO carries better survival rates and therefore ECMO instituted early maybe advantageous. Prolonged ECMO support has a direct correlation with mortality.

Comparison of skin dose measurement using nanoDot® dosimeter and machine readings of radiation dose during cardiac catheterization in children
Annals of Pediatric Cardiology 2018 11(1):12-16
Objectives : Direct measurement of skin dose of radiation for children using optically stimulated luminescence (OSL) technology using nanoDot® (Landauer, Glenwood, IL, USA). Background : Radiation dose is estimated as cumulative air kerma (AK) and dosearea product based on standards established for adult size patients. Body size of pediatric patients who undergo cardiac catheterization for congenital heart disease vary widely from newborn to adolescence. Direct, skindose measurement applying OSL technology may eliminate errors in the estimate. Materials and Methods : The nanoDot® (1 cm × 1 cm × flat plastic cassette) is applied to patient's skin using adhesive tape during cardiac catheterization and radiation skin doses were read within 24 hrs. nanoDot® values were compared to the currently available cumulative AK values estimated and displayed on fluoroscopy monitor. Results : A total of 12 children were studied, aged 4 months to 18 years (median 1.1 years) and weight range 5.3–86 kg (median 8.4 kg). nanoDot® readings ranged from 2.58 mGy to 424.8 mGy (median 84.1 mGy). Cumulative AK ranged from 16.2 mGy to 571.2 mGy (median 171.1 mGy). Linear correlation was noted between nanoDot® values and AK values (R2 = 0.88, R = 0.94). nanoDot® readings were approximately 65% of the estimated cumulative AK estimated using the International Electrotechnical Commission standards. Conclusions : Application of OSL technology using nanoDot® provides an alternative to directly measure fluoroscopic skin dose in children during cardiac catheterization. Our data show that the actual skin dose for children is approximately one-third lower than the AK estimated using international standards for adult size patients.

Coronary sinus atrial septal defect without persistent left superior vena cava: Three-dimensional imaging of a rare defect
Annals of Pediatric Cardiology 2018 11(1):103-105
Coronary sinus defects refer to interatrial communications that lie out of the confines of the atrial septum and leads from left to right shunt through the ostium of the coronary sinus. When associated with persistent left superior vena cava (PLSVC), mild systemic desaturation may occur depending on the extent of unroofing of the coronary sinus. Isolated defects without PLSVC are rare. Three-dimensional echocardiographic and surgical images are presented.

Normal reference ranges for cardiac valve cross-sectional areas in preterm infants
Annals of Pediatric Cardiology 2018 11(1):17-27
Objective : To establish normal reference ranges for cardiac valve crosssectional areas (CSAs) in preterm infants and their correlation with gestational age, body weight, and chronological age. Materials and Methods : In a prospective study, 268 preterm babies fulfilling the criteria for inclusion were examined. Echocardiograms were performed to measure aortic, pulmonary, mitral, and tricuspid valve CSAs on 0–6 day (s) of life and at weekly intervals until they reached 36 weeks. Gestational age was divided into three groups, 24–27, 28–31, and 32–35 weeks, and body weight was divided into five groups, ≤999, 1000–1499, 1500–1999, 2000–2499, and ≥2500 g. Overall group differences were compared for each period of life: 0–6 days and 1–2, 3–4, and ≥5 weeks. Results : The mean gestational age was 29.8 (±2.38 standard deviation [SD]) weeks, ranging between 24 and 35 weeks, and the mean body weight was 1479 (±413 SD) g, ranging between 588 and 3380 g. All cardiac valve CSAs correlated well with body weight. A significant gradual increase was observed in all valve CSAs with body weight during each period of life. Overall, a progressive and significant increase in all valve CSAs was observed during the first 9 weeks of life. Conclusions : Cardiac valve CSAs were found to be significantly correlated with body weight. The study also provides reference data, which can be used as a normal reference tool for valve CSAs in preterm infants against gestational age, body weight, and chronological age.

Evaluation of left ventricular function in obese children without hypertension by a tissue Doppler imaging study
Annals of Pediatric Cardiology 2018 11(1):28-33
Background : The prevalence of obesity is increasing worldwide. Obese children without hypertension are becoming an important health challenge. Aims : Complications of obesity in adults are well established, but in obese children, cardiac dysfunction has not been reported clinically. Settings and Design : The present crosssectional study investigates subclinical systolic and diastolic dysfunction using echocardiographic modalities. Materials and Methods : Twentyfive youngsters with body mass index (BMI) >30 and 25 healthy children with BMI <25 were assigned into case and control group, respectively. In all participants, complete cardiovascular examination, electrocardiography, and echocardiography were fulfilled. Echocardiography surveys included standard, pulsed wave Doppler (PWD), and tissue Doppler imaging (TDI). Statistical Analysis Used : SPSS software, version 24. Results : The two groups were matched for age and sex. The resting heart rate and blood pressure were markedly higher in the obese group (P = 0.0001) though they were within the normal range in either category. Ejection fraction in the two groups was similar. Left ventricular (LV) mass (P = 0.0001), LV mass index (P = 0.029), left atrialtoaortic diameter ratio (P = 0.0001), and LV enddiastolic diameter (P = 0.008) were significantly greater in the case group, indicating cardiomegaly and subclinical systolic and diastolic dysfunction. Except for the aortic velocity, all PWD variables were considerably lower in the case group, suggesting subclinical diastolic dysfunction. All TDI parameters varied significantly between the two categories. There was a direct correlation between isovolumetric relaxation time and BMI. Conclusions : Obesity in children without hypertension is associated with subclinical systolic and diastolic cardiac dysfunction. We propose the evaluation of blood pressure as well as myocardial performance using PWD and TDI in all obese children without hypertension, regularly.

Clinical presentation, management, and postnatal outcomes of fetal tachyarrhythmias: A 10-year single-center experience
Annals of Pediatric Cardiology 2018 11(1):34-39
Background : Limited information is available regarding the prevalence and outcomes of fetal tachyarrhythmias from the developing countries. Aims : This study aims to report referral patterns, management protocols, and pregnancy outcomes of fetuses with tachyarrhythmias reporting to a single center in South India. Methods : All fetuses with documented sustained fetal tachyarrhythmia during the study period (2008–2017) were included. Arrhythmia characterization and hemodynamic evaluation were done using fetal echocardiography. Patients were grouped into supraventricular tachycardia (SVT) and atrial flutter (AF) groups. Patient characteristics, transplacental therapy (TPT), pregnancy, and postnatal outcomes were analyzed. Results : Total of 19 fetuses included; 11 had SVT and 8 AF. Mean gestational age at referral was higher for AF (32.5 ± 3.2 vs. 29.6 ± 3.3 weeks; P = 0.05). Hydrops fetalis was present 8 (42%) fetuses; 4 in each group. TPT was instituted in 18 fetuses; 12 (66.7%) received combination therapy; 4 (21%) received direct fetal therapy. Eighteen fetuses (91%) were born alive with one intrauterine death in a fetus with SVT and severe hydrops. Seven (87.5%) fetuses with hydrops survived. Twelve patients (66.7%) were delivered in sinus rhythm. Six babies (33.3%) had tachycardia at birth requiring anti-arrhythmic therapy. All patients survived the neonatal period. Duration of trans-placental therapy (3.8 + 3.3 vs. 7.3 + 3.4 weeks) was shorter in the AF group. Conclusions : Aggressive TPT using combination of drugs achieves excellent pregnancy and postnatal outcomes in fetuses with tachyarrhythmia. Early diagnosis and prompt referral before hemodynamic decompensation is critical for ensuring optimal outcomes.

Exercise performance after univentricular palliation
Annals of Pediatric Cardiology 2018 11(1):40-47
Background : The optimal timing, need for primary/staged procedure in patients undergoing univentricular palliation, is debatable. Aims : We performed this study to assess the exercise performance of patients undergoing various forms of univentricular palliation. Setting and Design : This was a retrospective, prospective comparative study conducted at a multispecialty tertiary referral center. Patients and Methods : Between January 2012 and June 2015, 117 patients undergoing either bidirectional Glenn (BDG) (n = 43) or Fontan (total cavopulmonary connection [TCPC]) (n = 74) underwent exercise testing. Statistical Analysis : Comparisons between subgroups for continuous data were made with Student's ttest if normally distributed and Wilcoxon ranksum test otherwise. Tests between subgroups for qualitative data were made with Pearson's Chisquare test. Results : Patients who underwent BDG with open antegrade pulmonary blood flow (APBF) had higher saturations (oxygen saturation [SpO2]) compared to those without it (87.5 ± 5.0% vs. 81.1 ± 4.8%; P = 0.0001). However, we found no differences in exercise parameters of patients undergoing BDG with or without APBF. Extracardiac TCPC (n = 42) patients demonstrated better exercise capacity (15.0 ± 7.7 vs. 11.2 ± 6.2 min; P = 0.02) and increased SpO2 on exercise (87.0 ± 8.0% vs. 83.4 ± 7.6%; P ≤ 0.05) compared to lateral tunnel TCPC (n = 32). Fenestrated TCPC (n = 30) patients had higher exercise capacity reflected by higher metabolic equivalents (METs) consumption (6.4 ± 2.3 vs. 5.2 ± 2.0 METs, P = 0.02), fewer pleural effusions (7.0 ± 3.2 vs. 9.2 ± 6.2 days, P ≤ 0.05), and lower hospital stay (9.5 ± 4.0 vs. 12.7 ± 7.7 days, P = 0.04) compared to nonfenestrated TCPC (n = 44) patients. Conclusions : We observed no differences in exercise parameters of patients undergoing BDG with or without APBF. Extracardiac TCPC patients had better exercise capacity but longer postoperative hospital stay and pleural effusions than patients with lateral tunnel Fontan. Fenestrated TCPC patients seemed to fare better than nonfenestrated ones. Patients undergoing TCPC had better exercise capacity than patients undergoing BDG alone.

Impact of intensive care unit attending physician training background on outcomes in children undergoing heart operations
Annals of Pediatric Cardiology 2018 11(1):48-55
Background : The existing training pathways to become a pediatric cardiac intensivist are very variable with physicians coming from varied training backgrounds of pediatric critical care, pediatric cardiology, neonatology, or pediatric anesthesia. Aim : To evaluate the impact of cardiac Intensive Care Unit (ICU) attending physician training background on outcomes in children undergoing heart operations. Setting and Design : Patients in the age group from 1 day to 18 years undergoing heart operation at a Pediatric Health Information System database participating hospital were included (2010–2015). Patients and Methods : Based on the training background of majority of attending physicians in an ICU, the participating ICUs were divided into three groups: critical care medicine (CCM), cardiology, and indeterminate. Statistical Analysis : Multivariable logistic regression models were fitted to evaluate the association of ICU physician training background with study outcomes. Results : A total of 54,935 patients from 42 ICUs were included. Of these, 31,815 patients (58%) were treated in the CCM group (26 ICUs), 19,340 patients (35%) were treated in the cardiology group (12 ICUs), and 3780 patients (7%) were treated in the indeterminate group (4 ICUs). In adjusted models, no specific group based on ICU attending physician training background was associated with lower mortality (CCM vs. cardiology, odds ratio: 0.75, 95% confidence interval: 0.48–1.18), or lower incidence of cardiac arrest, or prolonged hospital length of stay, or prolonged mechanical ventilation. Conclusions : This large observational study did not demonstrate any impact of ICU attending training background on outcomes in children undergoing heart operations.

Transcatheter closure of postsurgical ruptured sinus of valsalva with amplatzer duct Occluder II AS™ device
Annals of Pediatric Cardiology 2018 11(1):86-88
Sinus of Valsalva (SV) rupture is a rare, cardiac complication after surgical repair of complex congenital heart disease. This paper reports a 4-year-old male child with double outlet right ventricle (RV) and pulmonary stenosis with superior-inferior arrangement of the ventricles, who was submitted to surgical repair using the "reparation a l'etage ventriculaire" procedure. A few months after an uneventful surgical repair, his clinical condition abruptly worsened because of the rupture of the right SV into the RV outflow tract resulting in large left-to-right shunt and RV functional impairment. To avoid surgical re-do, this late-onset complication was successfully treated by transcatheter implantation of an Amplatzer Duct Occluder Type II Additional Size™ (ADO-IIAS, St. Jude Medical Inc., St. Paul, Minnesota, USA) device.

Prognostic value of troponin in infants with hypoplastic left heart syndrome between Stage I and II of palliation
Annals of Pediatric Cardiology 2018 11(1):56-59
Background : The period between stage I and II procedure for treatment of hypoplastic left heart syndrome (HLHS) bears high mortality and morbidity. Methods : We sought to analyze the prognostic value of Troponin T/I (Trop), a well-recognized marker for myocardial damage and heart failure, for predicting outcome in a retrospective analysis of 70 infants with HLHS at our institution between March 2001 and October 2014. Results : Stage I procedure consisted of Norwood I operation in 35 (50%) and Hybrid-approach in 22 (31%) patients. Palliative care was chosen for 13 (19%) patients. Trop values were collected from clinical charts and were analyzed in relation to the overall outcome. Trop was significantly higher after Norwood I operation in comparison to Hybrid-approach (median 7.1 g/l (0.7-20.9), vs 1.2 g/l (0.3-17.9), P < 0.001). Overall mortality of treated patients was 39% (22 patients). Survival was 54% (19 patients) after Norwood and 73% (16 patients) after Hybrid-approach. Independently from the procedure used, maximal Trop and initial lactate values were significantly higher in non-survivors than in survivors, with median Trop of 9 g/l (0.6-18.8) vs. 3.4 g/l (0.4-20.9), P 0.007, and median lactate of 3.7 mmol/L (1.6-25) vs. 2.9 mmol/L (0.3-14.6), p 0.03. Reinterventions were required in 17 (30%) patients, 4 (11%) after Norwood and 13 (59%) after Hybrid procedure. No correlation was found between the need for reintervention and Trop levels in the interstage period. Conclusions : Patients with HLHS have significantly higher Trop levels after Norwood procedure than after Hybrid-approach. Maximal Trop values were related to mortality, but did not correlate with the need for reinterventions.

Discontinuity of the arch beyond the origin of the left subclavian artery in an adult: Interruption or coarctation?
Annals of Pediatric Cardiology 2018 11(1):92-96
Congenital aortic anomalies are uncommon causes of secondary hypertension and are seldom suspected in the adult age group. We present a case of aortic interruption unexpectedly diagnosed on autopsy in a 38-year-old male who presented with cardiovascular collapse. Apart from interruption, a finding unique to our case was aneurysmal dilation of the proximal descending aorta just before the obstruction with thrombosis. We also attempt to review the literature for interrupted aortic arch in adults and clarify the nomenclature of interruption versus coarctation.

Acquired ventricular septal defect due to infective endocarditis
Annals of Pediatric Cardiology 2018 11(1):100-102
Acquired intracardiac left-to-right shunts are rare occurrences. Chest trauma and myocardial infection are well-known causes of acquired ventricular septal defect (VSD). There have been several case reports describing left ventricle to right atrium shunt after infective endocarditis (IE). We present here a patient found to have an acquired VSD secondary to IE of the aortic and tricuspid valves in the setting of a known bicuspid aortic valve. This is the first case reported of acquired VSD in a pediatric patient in the setting of IE along with literature review of acquired left-to-right shunts.

Hemodynamic rounds: Can we mimic a temporary pulmonary artery band in catheterization laboratory in corrected transposition of great arteries with severe tricuspid regurgitation?
Annals of Pediatric Cardiology 2018 11(1):64-67
Right ventricular (RV) geometry is altered by septal shift after pulmonary artery banding. This may reduce tricuspid regurgitation (TR) and improve ventricular function in patients with corrected transposition of great arteries and systemic right ventricle. However, banding is risky in sick patients with severe RV failure. There are no predictive models in clinical practice to test this septal shift hypothesis before a risky surgery. A transcatheter model to mimic a pulmonary artery band is presented in corrected transposition of great arteries with failing right ventricle and severe TR.

Helicobacter pylori infection and occurrence of celiac disease in subjects HLA-DQ2/DQ8 positive: A prospective study
Abstract
Background
Celiac disease (CD) occurs in subjects positive for HLA-DQ2 and/or DQ8 gene loci at any age following ingestion of gluten-containing food. An increased permeability of the mucosa allows interactions between gliadin macromolecules and genetic factors. It has been observed that Helicobacter pylori has the ability to modulate the integrity of the duodenal epithelium. We aimed to determine whether H. pylori infection may enhance the occurrence of CD in genetically susceptible subjects.
Materials and Methods
This was a prospective observational study. Patients undergoing upper endoscopy for any reason and positive for HLA-DQ2 and/or DQ8 haplotypes with or without CD were included. H. pylori infection was defined as a positive gastric histopathology and/or 13C-urea breath test. Prevalence of infection was compared between enrolled subjects with and without CD. Multiple logistic regression analysis, adjusting odds ratios for patient age, gender, smoking habit, residency, body mass index, and assumption of nonsteroidal anti-inflammatory drugs (NSAIDs) and proton-pump inhibitors (PPIs) were performed.
Results
A total of 397 genetically susceptible individuals (mean age: 37.7 ± 15.3 years; 86% women) were enrolled between October 2014 and October 2017. There were 265 (68%) patients with a diagnosis of CD. Overall, the prevalence of H. pylori infection was 33% and was similar in patients with and without CD (32% vs 36%). Adjustment for all covariates did not reveal any significant association, although adjusted odds ratio (OR) for CD was higher in female (OR = 1.302), in patients H. pylori positive (OR = 1.277), followed by use of NSAIDs (OR = 1.126), respectively. The use of PPIs appeared to be mildly protective against CD (OR = 0.644).
Conclusion
Our study did not reveal any significant relationship between H. pylori and CD risk, even taking into account other confounders. More importantly, our findings do not support a "protective" role of H. pylori infection against CD, as previously reported. Therefore, there are no reasons to avoid eradication of H. pylori also in subject genetically susceptible for CD.

The effect of eradication of Helicobacter pylori on gastric cancer prevention in healthy asymptomatic populations
Abstract
Background
Although many epidemiologic studies have evaluated the effect of Helicobacter pylori eradication on gastric cancer, the effect is still uncertain in general populations. We evaluated whether H. pylori eradication would affect the incidence of gastric cancer in healthy asymptomatic populations.
Materials and methods
We performed a retrospective cohort study in 38 984 asymptomatic individuals, who underwent health screening examinations more than twice between 2005 and 2016. We investigated the incidence of gastric cancer among 3 groups: those without H. pylori infection (Hp-negative group), those with H. pylori eradication (eradication group), and those without H. pylori eradication (non-eradication group).
Results
The cumulative incidence of gastric cancer was 54.5 cases per 100 000 person-years during a median of 6.4 years. In a multivariate analysis using the Cox proportional hazard model, the cumulative incidence of gastric cancer in the non-eradication group was significantly higher than those in the Hp-negative (hazard ratio [HR] 4.12, P < .001) and eradication groups (HR 2.73, P = .001). However, the cumulative incidence of gastric cancer was not significantly different between the eradication and Hp-negative groups. Other risk factors for gastric cancer occurrence were age, smoking, family history of gastric cancer, and gastric atrophy. The standardized incidence ratios of the age groups above 40 and below 70 in the eradication group were all significantly decreased.
Conclusions
Helicobacter pylori eradication reduced the cumulative incidence of gastric cancer in healthy asymptomatic population, and the effect of H. pylori eradication on the prevention of gastric cancer was observed in all ages.
