BackgroundThe transition from adolescence to young adulthood marks a developmental period in which responsibility for management of chronic conditions such as food allergy shifts from the caregiver to the young adult. Fatal food-induced anaphylaxis is most common among adolescents and young adults. However, colleges are currently not well positioned to provide integrated support for students with food allergies.ObjectiveThe study objective was to explore the systems, structures, and policies that currently support students with food allergies at college, assess unmet needs, and develop pilot interventions through the use of patient-centered design processes.MethodsKey informant interviews were conducted with stakeholders in the campus management of food allergies (n = 26) between April and May 2016. Data were coded and assessed for relative frequencies of each code to determine challenges and potential solutions.ResultsThe convergence of stakeholder-identified themes indicated that the transition to college for students with food allergy would be improved by providing support for: (1) Notification of others in the student's campus network about food allergy; (2) Establishing clearly defined roles/responsibilities; and (3) Increasing campus awareness of food allergy signs, symptoms, and lethality. To better provide comprehensive support for students, 5 interventions—collectively called Spotlight—were developed.ConclusionThe use of qualitative research methods, patient-centered design processes, and collaborations with diverse stakeholders—including pediatricians that care for adolescents—can provide a framework for designing coordinated systems and policies to provide comprehensive support to college students with food allergy. Next steps include rigorously testing implementation of the Spotlight intervention prototypes.

Mannitol in Critical Care and Surgery Over 50+ Years: A Systematic Review of Randomized Controlled Trials and Complications With Meta-Analysis

Objective: Despite clinical use spanning 50+ years, questions remain concerning the optimal use of mannitol. The published reviews with meta-analysis frequently focused on mannitol's effects on a specific physiological aspect such as intracranial pressure (ICP) in sometimes heterogeneous patient populations. A comprehensive review of mannitol's effects, as well as side effects, is needed. Methods: The databases Medline (OvidSP), Embase (OvidSP), and NLM PubMed were systematically searched for randomized controlled trials (RCTs) comparing mannitol to a control therapy in either the critical care or perioperative setting. Meta-analysis was performed when feasible to examine mannitol's effects on outcomes, including ICP, cerebral perfusion pressure, mean arterial pressure (MAP), brain relaxation, fluid intake, urine output, and serum sodium. Systematic literature search was also performed to understand mannitol-related complications. Results: In total 55 RCTs were identified and 7 meta-analyses were performed. In traumatic brain injury, mannitol did not lead to significantly different MAP (SMD [95% confidence interval], CI)=−3.3 [−7.9, 1.3] mm Hg; P=0.16) but caused significantly different serum sodium concentrations (SMD [95% CI]=−8.0 [−11.0, −4.9] mmol/L; P

Combined Ex Vivo Hypothermic and Normothermic Perfusion for Assessment of High-Risk Deceased Donor Human Kidneys for Transplantation

Background Despite careful clinical examination, procurement biopsy and assessment on hypothermic machine perfusion (HMP), a significant number of potentially useable deceased donor kidneys will be discarded because they are deemed unsuitable for transplantation. Ex vivo normothermic perfusion (EVNP) may be useful as a means to further assess high-risk kidneys to determine suitability for transplantation. Methods From June 2014 to October 2015, 7 kidneys (mean donor age 54.3 years and KDPI 79%) that were initially procured with the intention to transplant were discarded based on a combination of clinical findings, suboptimal biopsies, long cold ischemia time and/or poor hypothermic perfusion parameters. They were subsequently placed on EVNP using oxygenated packed red blood cells and supplemental nutrition for a period of 3 hours. Continuous hemodynamic and functional parameters were assessed. Results After a mean cold ischemia time (CIT) of 43.7 hours, all 7 kidneys appeared viable on EVNP with progressively increasing renal blood flow over the 3-hour period of perfusion. Five of the 7 kidneys had excellent macroscopic appearance, rapid increase in blood flow to 200-250 ml/min, urine output of 40-260 ml/hr and increasing creatinine clearance. Conclusions Favorable perfusion characteristics and immediate function after a 3 hour course of EVNP suggests that high-risk kidneys subjected to long CIT may have been considered for transplantation. The combined use of ex vivo hypothermic and normothermic perfusion may be a useful strategy to more adequately assess and preserve high-risk kidneys deemed unsuitable for transplantation. A clinical trial will be necessary to validate the usefulness of this approach.

ObjectivesTo assess the accuracy of detecting and measuring buccal bone thickness (BBT) adjacent to titanium implants in CBCT images.Study DesignTitanium implants (one, two, or three), abutments, and metal-ceramic crowns were inserted into 40 bone blocks with various BBTs. CBCT images were acquired in various settings: voxel size (0.2 and 0.13 mm) and reconstruction section thickness (2.0 and 5.0 mm), and assessed by three examiners. True BBT was measured in digital photographs of the bone blocks. Buccal bone detection was evaluated by sensitivity and specificity. BBT was evaluated by one-way ANOVA between the true and the CBCT measurements, and by calculating the difference between the true measurement and the CBCT measurement (Di-BBT).ResultsDetection of buccal bone exhibited high sensitivity (0.86 – 1) and low specificity (0.14 – 1). More implants in the FOV, large voxel size, and thick image reconstruction sections had a negative impact on buccal bone detection. ANOVA showed statistically significantly larger BBT for the CBCT measurements in all settings (1.07 – 1.21 mm) compared with the true measurements (0.85 mm). Di-BBT was mostly within 0.5 mm.ConclusionsBBT adjacent to titanium implants is overestimated when evaluated in CBCT cross-sectional images.

Objective: Myofascial pain in temporomandibular joint disorders (TMD) is evoked by various factors including edematous change. We investigated whether the pain pattern is related to edematous change using a T2 mapping generated by magnetic resonance imaging to detect water content in the tissue.Study designOne hundred and five patients diagnosed with TMD with and without unilateral masseter muscle pain were divided into six groups according to their pain experience: pain on compression (23 cases), pain on movement (13 cases), spontaneous pain (4 cases), pain on compression and movement (14 cases), pain on compression and spontaneous pain (2 cases) and no pain (49 cases). Differences in the mean T2 values of the masseter muscle between the painful and pain-free sides (5 unilateral pain groups) or the right and left side (pain-free group) were compared with paired t-tests. Significant differences were assumed at p < 0.05.ResultsSignificant differences in mean T2 values were found between the painful and pain-free side in the pain on compression group.ConclusionThe findings of edematous change in the masseter muscle of patients with pain on compression may affect treatment planning and lead to investigation of treatment options for myofascial pain in TMD.

Clinical feasibility and efficiency of a 3-dimensional printed surgical template for mandibular angle osteotomy and mandibular angle splitting osteotomy

Mandibular angle osteotomy (MAO) and mandibular angle splitting osteotomy (MASO) are the two main surgical approaches used to correct a square mandible for a desirable aesthetic appearance. However, there are concerns about the safety and accuracy of both procedures as they may lead to unsatisfactory results such as injury to the nerve. To achieve symmetry and security we designed and evaluated a 3-dimensional printed surgical template, which indicates the outer cortex splitting line of the MASO, and the curved cutting line of the MAO.

Costochondral grafting for paediatric temporomandibular joint reconstruction: 10-year outcomes in 55 cases

Costochondral grafting (CCG) can be used for the reconstruction of ankylotic, hypoplastic, and resected temporomandibular joint (TMJ) defects. CCGs have previously been considered the gold standard in children due to their growth potential and autogenous origin, but the disadvantages are unpredictable growth and joint ankylosis. This was a retrospective study of all children who received CCGs for TMJ reconstruction from 1985 to 2004, to allow a 10-year follow-up. Fifty-five patients were included in this study, with 74 grafts being placed; their mean age was 7.9±4.2years.

Extended total temporomandibular joint replacements: a classification system

Publication date: Available online 27 June 2018
Source:British Journal of Oral and Maxillofacial Surgery
Author(s): R. Elledge, L.G. Mercuri, B. Speculand
Prosthetic total temporomandibular joint (TMJ) replacement (TJR) is well established in the United Kingdom, with clear guidelines for indications and nationally published outcomes. CAD/CAM technology has made it possible to push the boundaries of custom-made TJR to include extended versions (eTJR), which may replace segmental mandibular defects or defects in the skull base with extended components for the ramus and fossa, respectively. Such prostheses are uncommon, and published reports are restricted to isolated cases and series of cases. We know of no previous attempts to classify such prostheses, and here we suggest a bipartite classification system for use in communications between surgeons and manufacturers based on a review of 19 prostheses provided by one manufacturer (TMJ Concepts, Ventura, CA).

AHR signaling in the development and function of intestinal immune cells and beyond

Abstract

The intestinal immune system is challenged daily with the task of recognizing and eliminating pathogens while simultaneously tolerating dietary and commensal antigens. All components must effectively coordinate to differentiate a continual barrage of environmental cues and mount appropriate responses dependent on the nature of the stimuli encountered. Playing a pivotal role, the aryl hydrocarbon receptor (AHR) is a chemical sensor that detects both dietary and microbial cues and is important for development, maintenance, and function of several types of intestinal immune cells, particularly innate lymphoid cells (ILCs) and T cells. In this review, we will highlight recent advances in our knowledge of the role of AHR signaling in ILCs, T cells, B cells, and dendritic cells.

Brown-Vialetto-Van Laere syndrome: a novel diagnosis to a common presentation

Brown-Vialetto-Van Laere syndrome (BVVLS) or riboflavin transporter deficiency (OMIM 211530) is a rare treatable autosomal recessive neurodegenerative disorder. This condition is associated with progressive pontobulbar palsy. We describe the clinical course of a 16-month-old boy with BVVLS and a novel homozygous mutation from Pakistan. Our patient presented with stridor and respiratory insufficiency. Hearing loss which is the most common sign of this condition was absent, making it an unusual presentation of BVVLS. His examination revealed ptosis and tongue fasciculation. His riboflavin receptor mutational analysis showed the homozygous mutation in the SLC52A3 gene. Per oral riboflavin was administered, and subsequently, he was able to be weaned off the ventilator. Now the child is improving and attaining developmental milestones.

New headaches with normal inflammatory markers: an early atypical presentation of giant cell arteritis

An 80-year-old man presented repeatedly to his general practitioner with 3 months of unexplained persistent frontal headaches. CT head revealed no diagnosis. His dentist diagnosed his co-existing jaw pain as bruxism. Three months later, the patient happened to attend a routine ophthalmology follow-up appointment. During this routine appointment, features of giant cell arteritis (GCA) including worrying visual complications were first noted. His inflammatory markers (C-reactive protein and erythrocyte sedimentation rate) were not significantly raised—contrary to the norm. A temporal artery ultrasound and biopsy were performed, in light of the history. This confirmed GCA. He was commenced on high-dose oral prednisolone and was managed by ophthalmology and rheumatology. At 4 weeks, symptoms resolved with no permanent visual loss despite a prolonged initial symptomatic period. Multiple symptomatic presentations to different specialties should therefore alert clinicians to a unifying diagnosis, for example, vasculitis. Serious illnesses may present with severe symptoms despite normal screening investigations.

Perioperative continuous glucose monitoring in a preterm infant

Surgery in the neonatal period presents challenges, especially in preterm infants weighing <1 kg. Their small size, minimal reserves and physiological immaturity means attention to detail and careful monitoring is critical to avoid cardiovascular instability; maintaining fluid balance and metabolic stability is also problematic due to often limited vascular access and small blood volumes. Developments in technology have meant that cardiovascular parameters such as heart rate, blood pressure and oxygen saturations are all routinely and continuously monitored before and during surgery.

We have been exploring the role of continuous glucose monitoring (CGM) for metabolic monitoring and management of glucose control in very preterm infants (24–32 weeks gestation). In this paper, we report on a preterm infant who uniquely underwent surgery while wearing a continuous glucose monitor, blinded to the clinical team. This case highlights the metabolic vulnerability of these babies and a possible role for real-time CGM during surgical procedures.

Intravenous immunoglobulin for severe thrombocytopenia in secondary dengue

A 30-year-old woman with severe dengue presented on the sixth day of her illness with life-threatening thrombocytopenia, refractory to multiple platelet transfusions. Dengue IgM antibody and the non-structural-1 antigen tests as of day 3 were negative. The IgG antibody against the same was positive, suggesting a past episode of dengue. Since she had a history of menorrhagia prior to the current illness, a working diagnosis of idiopathic thrombocytopenic purpura was made, for which intravenous immunoglobulin (IVIg) was administered that led to a rapid rise in the platelet count with no adverse events. Subsequently, dengue IgM antibody repeated on day 6 came back positive, confirming dengue. This case report re-emphasises the potential use of IVIg in patients with severe thrombocytopenia in dengue.

Cloudy Cornea with Arcus Juvenilis in a Case of Dense Deposit Disease

A 25-year-old male patient presented with complaints of blurred vision in both eyes since 2 years. The patient was a known case of nephrotic syndrome with dyslipidaemia for which he was on diuretics and lipid-lowering agents for 3 years. On examination, his visual acuity was 6/9 in both eyes with cloudy cornea and arcus juvenilis. Fundus examination was within normal limits. On systemic work-up, his lipid profile was deranged with increased serum total cholesterol, very low density lipoprotein, low density lipoprotein and triglyceride. The serum high density lipoprotein was decreased. Renal function test revealed elevated serum creatinine with significant proteinuria. Renal biopsy was suggestive of dense deposit disease on immunofluorescence and transmission electron microscopy. Ocular manifestation of dense deposit disease is characterised by retinal drusen, pigmentary atrophy, choroidal neovascular membrane and atypical serous retinopathy. To the best of our knowledge, anterior segment changes in dense deposit disease has not been reported. This is the first case reporting cloudy cornea with arcus juvenilis in a case of dense deposit disease.

Dural arteriovenous fistula presenting with acute subdural haematoma showing impending cerebral herniation

A dural arteriovenous fistula (DAVF) presenting with acute subdural haematoma (ASDH), which were not related to head injury, is rare. A 61-year-old woman was transported by ambulance because of deterioration of consciousness. On admission, she was comatose with anisocoria. Emergent CT demonstrated a severe midline shift associated with a left ASDH and an additional left occipital intracerebral haematoma, both of which had no continuity with each other. MRI showed flow void signs in the left occipital lobe. Because of the impending cerebral herniation, an emergent evacuation of the ASDH and external decompression was performed. Subsequent evaluation revealed a DAVF at the left occipital convexity near the confluence with retrograde leptomeningeal venous reflux and venous ectasia (Cognard type III DAVF). The patient underwent endovascular treatment for the DAVF involving transarterial embolisation using coils and N-butyl cyanoacrylate with complete obliteration. Her further clinical course was uneventful and discharged after cranioplasty.

The immunobiology of ubiquitin-dependent B cell receptor functions

Publication date: September 2018
Source:Molecular Immunology, Volume 101
Author(s): James R. Drake
MHC class II-restricted antigen presentation by dendritic cells is necessary for activation of naïve CD4 T cells, whereas class II-restricted antigen presentation by B lymphocytes and macrophages is important for the recruitment of CD4+ helper and regulatory T cells. Antigen presentation by B cells is also important for induction of T cell tolerance. B cells are unique among these three types of MHC class II-expressing antigen presenting cells (APC) as they constitutively express high levels of cell surface class II molecules and express a clonally restricted antigen specific receptor, the B cell receptor (BCR). Here, I review our current understanding of three major steps that underlie the processing and presentation of BCR-bound cognate antigen: (1) endocytosis of antigen-BCR (Ag-BCR) complexes, (2) Ag-BCR trafficking to intracellular antigen processing compartments and (3) generation of antigenic peptide-MHC class II complexes, with a particular focus on the role of BCR ubiquitination in each. I will highlight potential topics for future research and briefly discuss the impact of the cell biology of BCR-mediated antigen processing on the response of the B cell and T cell to the cell-cell interactions mediated by B cell-expressed peptide-class II complexes.

Upon bacterial infection, activated MAIT cells produce diverse cytokines and cytotoxic effector molecules and accumulate at the site of infection, thus, MAIT cells have been shown to be protective against various bacterial infections. Here, we summarize the current knowledge of the role of MAIT cells in bacterial pulmonary infection models.

Complement C3a receptor modulates embryonic neural progenitor cell proliferation and cognitive performance

Publication date: September 2018
Source:Molecular Immunology, Volume 101
Author(s): Liam G. Coulthard, Owen A. Hawksworth, Jacinta Conroy, John D. Lee, Trent M. Woodruff
The complement system of innate immunity is emerging as a novel player in neurodevelopmental processes. The receptor for C3a, C3aR, shares a close evolutionary and functional relationship with C5a receptors. Whilst the C5a receptor, C5aR1, has been demonstrated to promote embryonic neural stem cell proliferation, little is known about the role of C3aR in this process. Here we show that C3aR is expressed in a similar manner to C5aR1 in mice, at the apical pole of the embryonic ventricular zone, though it has an opposing function. Using in utero delivery of C3aR agonist and antagonist compounds to the embryonic ventricle, we demonstrate that C3aR functions to decrease proliferation of apical neural progenitor cells (NPC). Intriguingly, C3aR^-/- animals also have altered NPC proliferation, but demonstrate an opposing phenotype to animals subjected to pharmacological blockade of C3aR. Finally, despite a grossly normal development of C3aR^-/- animals, cognitive behavioural testing of adult mice showed subtle deficits in recall memory. These data demonstrate that in addition to C5a, C3a also has a critical role in the normal development of the mammalian brain.

High lingual split access osteotomy for ectopic third molar in mandibular ramus region – A case report and literature review

Publication date: Available online 26 June 2018
Source:Journal of Oral Biology and Craniofacial Research
Author(s): Cathrine Diana, Ranjeet Bodh, Pankaj Sharma, Anjali Verma
Ectopic occurrence of mandibular third molar is a rare incidence. Usually found along with a cystic lesion or diagnosed incidentally during routine check -up. Owing to the rarity, only few cases were reported in the literature. The common site is the mandibular condyle followed by sigmoid notch, and often found in females. The frequent symptoms are obscure facial pain, trismus or the symptoms of the associated pathology like dentigerous cyst. The etiopathogenesis is uncertain and optimal management is still unclear.The symptomatic tooth should be removed either intra- orally or extraorally. Here we report a case of ectopic mandibular third molar in ramus region surgically removed intra orally by high lingual split access osteotomy.

PurposeThe aim of this study was to evaluate the effect of different storage media on angiogenesis and maintaining autogenous bone graft volume in rabbits.Material and MethodsTwo grafts were removed bilaterally from calvaria of 18 rabbits. One graft was removed and immediately fixed in the right mandibular angle (Control group). The other graft was stored for 30 minutes in one of the following storage media (n=6): Saline solution (Saline group), Air exposure (Dry group), Platelet-poor plasma (PPP group), and then screw-retained in the right mandibular angle, in the same animal. Four weeks later the animals were euthanized, and the grafted areas were harvested and fixed in 10% phosphate buffered formaldehyde solution and embedded in paraffin. The 5μm semi-sections were stained in hematoxylin-eosin and mallory trichrome.ResultsThe histological analysis of all groups showed bone graft vascularized and well-incorporated into the recipient site. Blood vessels decreased in number in the Saline and Dry groups compared with Control groups (p<0.03); however, blood vessels increased in the PPP group (p<0.05). Osteoclasts were lower in number than in Saline group compared with Control group (p<0.05). Furthermore, the Saline group showed higher numbers of blood vessels than Dry group (p<0.01). PPP group showed higher bone graft volume values compared with Dry and Saline Group (p<0.01). In addition, Saline group showed higher bone graft volume values than Dry group (p<0.01).ConclusionsThe PPP improved angiogenesis, maintained volume of autogenous bone graft, and was a better storage media in the trans-surgical period than dry and saline solution.

Author(s): Xiaolong Li, Debra L. Safer, Imilce Castro Paz, Roseanne Menorca, Sabine Girod
PurposeNearly 10% of patients remain dissatisfied after orthognathic surgery, largely because of psychoeducational or psychosocial factors. The purpose of this study was to evaluate the feasibility and acceptability of a psychoeducationally based group intervention to improve preoperative preparation of orthognathic surgical patients and their caregivers.Materials and MethodsThe intervention consisted of 2 group sessions, with each session lasting 2 hours. The sessions provided realistic expectations of the surgery, offered teaching strategies for coping with pre- and postoperative symptoms of psychopathology, and highlighted the importance of social support. Feasibility was based on attendance, homework completion, and data collection rates, and acceptability was based on post-treatment participant satisfaction scores on the Client Satisfaction Questionnaire–8 (CSQ-8) and credibility and expectancy scores on 2 subscales of the Credibility/Expectancy Questionnaire–Modified (CEQ-M).ResultsTwenty-six orthognathic surgical patients were recruited from an outpatient oral and maxillofacial surgery clinic to attend the group-based intervention. Seventy percent of patients who attended at least 1 session completed the 2 sessions, and 64% of those who attended the 2 sessions completed at least 1 homework assignment. The authors successfully collected 84% of the total measures given to patients and their caregivers. The mean satisfaction rating of the patients was 30.12 of 32 (CSQ-8; n = 13; standard deviation [SD], 2.33), the mean credibility rating of the patients and their caregivers was 25.2 of 27 (CEQ-M; n = 20; SD, 1.85), and the mean expectancy rating of the patients and their caregivers was 20.54 of 27 (CEQ-M; n = 20; SD, 4.39).ConclusionThe psychoeducationally based group intervention was feasible and acceptable for participants and their caregivers. This article offers suggestions to further improve the feasibility and acceptability of the intervention, including optimizing standardization of data collection procedures, decreasing barriers to access, and increasing participant engagement.

PurposeThe aims of the present study were to discuss the demographic distribution and clinical characteristics of pycnodysostosis (PYCD) patients, as well as the onset of osteomyelitis and its treatment using a literature review. We also report an update of treatment of mandibular osteomyelitis in a PYCD patient using a buccal fat pad (BFP) as a free graft.Patients and MethodsThe study was carried out in two steps. In the first part, an electronic search was undertaken in PubMed in March/2018, with 17 articles being included. In the second, we report a case of mandibular osteomyelitis in a 30-year-old female patient with PYCD treated by sequestrectomy and with the use of a BFP as a free graft, with a follow-up of 24 months.ResultsTwenty-one cases reported osteomyelitis of the jaws in PYCD patients. Dental extraction, mandibular fracture and one case of facial trauma represented the causes of mandibular osteomyelitis. Treatment performed by the authors included: resection associated with antibiotics and sequestrectomy alone or associated with antibiotics.ConclusionDespite the good results of the case presented here, further studies using BFP as an adjuvant key for jaw osteomyelitis are necessary to elucidate its clinical efficiency and safety.

Frontal Sinus Morphology: A Reliable Factor for Classification of Frontal Bone Fractures?

Publication date: Available online 22 June 2018
Source:Journal of Oral and Maxillofacial Surgery
Author(s): Johannes Buller, Volker Maus, Andrea Grandoch, Matthias Kreppel, Matthias Zirk, Joachim E. Zöller
PurposeThe frontal sinus shows a wide range of morphologic variations. The aim of this study was to evaluate the influence of frontal sinus size on fracture characteristics in frontal bone trauma.MethodsIn this cross-sectional study, patients with traumatic fractures of the frontal bone were retrospectively collected from the institution's database. Radiometric analysis of computed tomography (CT) and cone-beam CT data sets was performed. Frontal sinus size was measured as variables height, width and depth. The secondary predictor was morphologic sinus type according to Guerram's classification of hyperplasia, medium size, hypoplasia or aplasia of the frontal sinus. To determine outcomes, we classified fractures into the following categories: isolated to the anterior table, combined fractures of the anterior and posterior table, isolated to the posterior table and frontal bone fracture without sinus involvement. Further study variables were patients' demographics, combined midfacial fractures, orbital rim involvement, fracture displacement and surgical approach. For statistical analysis, fracture types were assessed for frontal sinus metric size and morphologic type using bivariate tests with p-value <0.05 defined as significant.ResultsWe enrolled 53 consecutive patients with a mean age of 35 years, including 93% males. Fracture types differed significantly in sinus width, height (both p < 0.001) and depth (p = 0.002). Frontal sinus morphology was hyperplastic in 66%, medium in 30.2%, and hypoplastic in 3.8%. Hyperplastic frontal sinus had an increased likelihood of isolated anterior table fractures (odds ratio: 6.0, p = 0.007) compared to medium-sized types. Fractures without sinus involvement were more likely in hypoplastic and medium types (p < 0.001).ConclusionThe morphology of the frontal sinus determines the probability of fracture types from craniofacial trauma. Thus, the frontal sinus size appears to be a major factor for frontal bone resistance to traumatic force impingement.

A march by any other name

The allergic (or atopic) march refers to the natural history of allergic diseases as they develop during infancy and childhood. The march conventionally begins with atopic dermatitis (AD) and progresses to IgE-mediated food allergy (IgE-FA), asthma, and allergic rhinitis (AR).1 The observation that allergic manifestations tend to develop in this stereotyped progression stems from decades of observational research, including birth cohort studies. It has also been the basis for large, longitudinal studies of individual disease associations.

Pituitary 'pseudotumor: an under-recognised complication of undertreated primary hypothyroidism

Description 

A woman in her 30s with medical history notable for hypothyroidism due to Hashimoto's thyroiditis had a brain MRI ordered by her neurologist due to change in chronic headache pattern. This had an incidental finding of enlarged pituitary gland. She was referred at that time to an endocrinologist but was not seen. Eighteen months later, she presented with worsening headaches, blurry vision, weight gain and galactorrhoea. Repeat brain MRI showed a 9x10x13 mm sellar mass extending superiorly, with mass effect on optic chiasm (figure 1A). Thyroid-stimulating hormone (TSH) was 185 mIU/mL with low free T3, low free T4, normal prolactin, normal FSH and normal LH. She was then referred to a neurosurgeon and an ophthalmologist. Visual field testing initially showed mild constriction of bilateral visual fields. The neurosurgeon referred her to an endocrinologist for preoperative hormonal evaluation, but the operation date was advanced when subjective visual...

'Toxic ST elevation

Description 

A young man was admitted to the emergency department after consuming zinc phosphide, with severe drug refractory hypotension. ECG (refer figure 1) revealed ST segment elevation involving anterior, lateral and inferior leads. Serum levels of potassium, calcium, magnesium and phosphorous were normal; serum troponin-T was 1126 ng/nL (upper limit of normal 14 ng/nL), with associated metabolic acidosis. Echocardiogram revealed severe left ventricular systolic dysfunction. Severe myocardial depression with histopathological evidence of myocyte vacuolation and myocytolysis has been occasionally described with aluminium phosphide toxicity, primarily mediated by phosphine. The absence of an antidote makes the mortality high, once refractory shock ensues. Our patient succumbed to this condition. Zinc phosphide toxicity mediated by phosphine can have similar multisystem involvement, though dramatic electrocardiographic changes are uncommon.1 2 However, as evidenced by our report, ST segment elevation involving multiple leads on the ECG, though rare, maybe a hazardous manifestation...

Unusual foreign body impacted in the upper oesophagus: original technique for transoral extraction

Foreign body ingestion is a common event; in the adult population, most ingestions occur in patients with mental disability, psychiatric disorders, alcohol intoxication or in prisoners seeking secondary gain. Removal through flexible endoscopy is generally the first-line approach but rescue oesophagotomy may be necessary for foreign bodies impacted in the upper oesophagus. A 27-year-old man was admitted in the emergency room after intentional ingestion of a wooden spherical object with a central hole. A total body CT scan showed that the object was completely obstructing the upper oesophageal lumen but there were no signs of perforation. In the operating room, a Weerda diverticuloscope and a 5 mm 0° telescope were used to visualise the foreign body under general anaesthesia. A standard endoscopic biopsy forceps was passed through the hole of the sphere and was retracted with the jaws open allowing transoral extraction without complications.

Hidden burden of osteoporosis in alpha-1 antitrypsin deficiency

This is a reminder of a rare cause of osteoporosis that remains widely underdiagnosed and lacks specific evidence on its optimal management. We bring a case report of a patient presenting with erectile dysfunction and high testosterone level but also elevated sex-hormone binding globulin hence low free androgen index as well as evidence of organ specific hypogonadal side effects such as osteoporosis. A unifying diagnosis of alpha-1 antitrypsin deficiency (AATD) brought together his coexistent mild chronic obstructive pulmonary disease as well as a new finding of previously unrecognised liver disease. This case highlights the uncertainties over the mechanism of osteoporosis in AATD as well as the controversies over best way to manage it. The efficacy of testosterone replacement in managing osteoporosis in the context of AATD remains untested. National registries for AATD would be best placed at gathering further evidence in this area.

Late-onset TNF receptor-associated periodic syndrome presenting as recurrent urticarial rash and lymph nodes

Description 

A 35-year-old Caucasian woman was referred by a general practitioner to our medical ward because she was suffering from recurrent arthralgia, urticarial rash with mild pruritus and cervical lymph nodes. There was no sign of arthritis, any fever, chills or night sweats, but she had lost 2.5 kg in 3 months. The average lengths of symptoms were more than 6 weeks.

She presented the same symptoms with cervical lymph nodes when she was 24 years old. She received doxycycline for a suspicion of Lyme disease and the evolution was favourable after 2 weeks of treatment. However, serology was not compatible with recent Lyme disease. Since then, the frequencies of the attacks were rare but occurred once a year.

The routine blood tests were normal except a slightly elevated C reactive protein at 12 mg/L (normal value <5 mg/L). Infectious serologies for Cytomegalovirus, Epstein-Barr virus, HIV, hepatitis C and B, Brucella, Bartonella henselae and...

Severe, reversible dysphagia and malnutrition in a patient with tumour-induced hypophosphataemia

Up to 20% of hospitalised patients may have low serum phosphate concentrations. In certain groups, such as patients with chronic alcohol overconsumption, severe trauma or sepsis, the prevalence may be 30%–50%. Profound hypophosphataemia is less common, but may lead to severe physiological disturbances. In rare cases, hypophosphataemia is caused by phosphaturic substances excreted from a tumour. Osteomalacia with chronic bone pain and fractures, as well as muscle weakness, is common in such patients. The tumours are often small and difficult to detect. Studies suggest that fibroblast growth factor 23 is a reliable marker for detection of these tumours. Persistent hypophosphatemia unresponsive to supplements should raise clinical alertness. With complete resection of the neoplasm, the symptoms rapidly reverse. If the tumour cannot be removed, treatment relies on supplementation with phosphate and active vitamin D compounds. We present a case report of a patient with severe hypophosphataemia, osteomalacia, dysphagia and malnutrition.

Successful treatment of intractable visual hallucinations with 5-HT2A antagonist ketanserin

Hallucinations, visual, auditory or in another sensory modality, often respond well to treatment in patients with schizophrenia. Some, however, do not and can be very chronic and debilitating. We present a patient with schizophrenia with intractable hallucinations despite state of the art care, including high-dose clozapine and transcranial magnetic stimulation. Based on the possible role of the 5-HT_2A receptor in hallucinations, we treated her with the antihypertensive drug ketanserin, a 5-HT_2A receptor antagonist.

This significantly reduced her visual but not her auditory hallucinations, suggesting a possible role of the 5HT_2A receptor in the pathophysiology of specifically visual hallucinations. This is the first time ketanserin has been described to successfully reduce visual hallucinations in a patient with schizophrenia.

Use of indocyanine green dye clearance in a patient with liver cirrhosis undergoing hepatectomy: a clinical image

Description 

Indocyanine green (ICG) is a water-soluble, non-toxic tricarbocyanine dye extracted exclusively from the hepatic parenchyma. Measurement of ICG clearance using pulse spectrophotometry is a simple, reproducible and non-invasive test, easily performed in the operating room. ICG plasma disappearance rate (PDR) and the retention rate at 15 min (R15) produce real-time metrics to aid assessment and decision-making before, during and after complex liver surgery. ICG clearance has also been used to suggest the presence of postoperative complications, including thrombosis of the hepatic artery and graft dysfunction following liver transplantation. We present a case of 65-year-old Caucasian man, with Child-Pugh A liver cirrhosis undergoing complex right hepatectomy for metastatic colorectal liver cancer where ICG clearance impacted on the extent of surgical resection.

Given the concerns about marginal postoperative liver function of the residual left hepatic lobe, we used pulse spectrometry intraoperatively to predict the risk of postoperative liver dysfunction. Immediately preoperatively, a...

Post-traumatic pseudoaneurysm of brachial artery in multiple hereditary exostoses

Pseudoaneurysms adjacent to exostoses have been commonly reported in the femoral and popliteal arteries and only rarely in the upper extremity. We describe a case of an 18-year-old man with multiple hereditary exostoses who developed a brachial artery pseudoaneurysm after minor trauma to his right upper arm, adjacent to a known lesion. He was referred to a vascular surgeon who removed the pseudoaneurysm and repaired the artery with a saphenous vein graft. We encourage a high suspicion of vascular injury even after minor trauma when an osteochondroma is adjacent to a vascular structure.

Perforated caecal carcinoma masquerading as lower limb necrotising fasciitis: lessons learnt

A 69-year-old man was admitted with non-resolving right leg cellulitis. Subsequent skin changes over the calf and discharging pus suggested necrotising fasciitis. After several wound debridements of the leg and imaging, the patient was found to have an iliopsoas abscess due to a metastatic perforated caecal tumour extending along the medial thigh to the calf. No micro-organisms indicative of typical necrotising fasciitis were isolated from the wound. The patient had an ileocaecal resection, and his leg was reconstructed with a split thickness skin graft. He continues to do well postoperatively. This case highlights key lessons when dealing with an unusual presentation leading to challenges in diagnosis such as: (1) the need for good interspecialty liaison, (2) prompt senior review and plan, and (3) 'thinking outside the box' when faced with a diagnostic challenge.

Steroid-induced protracted severe ocular hypertension in a 14-year-old girl

Steroid-induced ocular hypertension (SIOH) is a challenging entity in paediatric age, with many being refractory to medical therapy. Literature is scarce about surgical options in these cases. A 14-year-old girl with bilateral uveitis and macular oedema had received an intravitreal and subconjunctival triamcinolone injection in the right (OD) and left (OS) eye, respectively. While the steroid was effective in resolving the oedema, intraocular pressure (IOP) increased to about 40 mm Hg OD and 34 mm Hg OS, despite being under maximal IOP-lowering therapy. An initial conservative approach was preferred due to the young patient age and given that most cases of SIOH are transient. However, progressive structural changes were documented, and bilateral sequential minimally invasive glaucoma surgery (MIGS: XEN gel stent) was taken. With a follow-up of 6 months, the patient is drug-free with IOP around 14 mm Hg. This report discusses the role and efficacy of MIGS in a paediatric case of SIOH.

Long-term complete remission of a patient with high grade neuroendocrine carcinoma of ampulla of Vater

We describe a case report of a 53-year-old man with a 5-months history of progressive jaundice and upper abdominal pain. The patient was further evaluated and finally diagnosed with a high-grade ampullary neuroendocrine tumour (based on endoscopic-guided biopsy). Thereafter, he underwent pancreatoduodenectomy and adjuvant platinum-based chemotherapy. This extremely rare case presents his long-lasting disease-free survival compared with similar cases; this case report exemplifies a new, potentially efficient method for treating high-grade papillary neuroendocrine tumour and may pave the way for further clinical trials utilising this blueprint in the treatment of related conditions.

Giant arachnoid granulation with a thrombosed dural arteriovenous fistula

Arachnoid granulations are common incidentally detected small dural lesions which are usually asymptomatic and follow cerebrospinal fluid density/signal intensity on CT/MRI. Such lesions reaching a size of more than 1 cm are termed as giant arachnoid granulations (GAGs) which have been previously reported to cause venous hypertension and headaches. We report a case of GAG involving the proximal half of the superior sagittal sinus in a 45-year-old male patient which was associated with left temporal thrombosed dural arteriovenous fistula (AVF) whose thrombosed draining veins were seen converging towards the site of GAG. The patient presented with three episodes of generalised tonic-clonic seizures and improved with conservative treatment. No reports of such association of GAG with AVF is available in the literature, and we believe it could have occurred due to venous hypertension induced by GAG.

Acute torsion of a wandering spleen: a paediatric emergency

Description

A 5-year-old boy presented to the emergency department with intense dull aching pain in the left lower abdomen. On physical examination, his vitals were stable. A well-defined, tender, firm, 10x6 cm sized mass was palpable in the left lower abdomen occupying the left hypochondrium, left lumbar and umbilical regions. Urgent ultrasound revealed the absence of spleen in the normal position with a hypoechoic encapsulated mass in the left lower abdomen while Doppler study showed the absence of internal vascularity in it. Contrast-enhanced CT (CECT) of the abdomen (figure 1A,B) confirmed the presence of an enlarged, minimally enhancing and inferiorly displaced spleen with characteristic 'whirled appearance' of the splenic hilum. The diagnosis of splenic torsion was confirmed and an exploratory laparotomy was performed. Intraoperatively, the spleen was torsed 720 degrees on its pedicle with an engorged and thrombosed splenic vein (figure 2A,B). The ligamentous attachments (gastrosplenic, splenocolic,...

Non-arteritic anterior ischaemic optic neuropathy secondary to menorrhagia in a young healthy woman

Non-arteritic anterior ischaemic optic neuropathy (NAION) may develop due to severe anaemia and hypotension which is seen in acute blood loss. The devastating visual loss is often irreversible. We report a case of NAION in a 20-year-old healthy woman, who presented on the third day of a heavy menstrual cycle with hypovolaemic shock. On day 2 of admission, she had sudden right eye blurring of vision at the superior field on awakening from sleep. Funduscopy revealed a pale and swollen right optic disc. There was a dense right superior altitudinal visual field defect. Her haemoglobin level was low (3.6 g/dL), but she refused blood transfusion due to her religious belief (Jehovah's Witness) and opted for conservative management. She later developed right optic atrophy with persistent visual field defect despite an improved haemoglobin level of 10.5 g/dL.
