Evidence establishing a link between prenatal and early-life stress and asthma development

Wiring taste receptor cells to the central gustatory system
Abstract
Taste receptor cells in the tongue are epithelial in nature and turnover frequently. Taste receptor cell-associated neurons carrying bitter, sweet or sour signals never turnover and are hardwired to specific gustatory centers in the brain. How can ever-changing bitter or sweet receptors find never-changing neurons that must match the specificity of the signal? This article reviews a recent paper published in Nature (Lee et al., 2017, 548:330-333) that identified two molecules belonging to the semaphorin axon guidance family of molecules (SEMA3A and SEMA7A) that help maintain the "labelled line principle" between peripheral bitter or sweet receptors and their respective central projection area in the gustatory center.

Endoscopic ultrasonography (EUS)-guided laser ablation (LA) of adrenal metastasis from pancreatic adenocarcinoma
Abstract
Endoscopic ultrasonography (EUS)-guided laser ablation (LA) is potentially applicable to tumours in the left lobe of the liver and pancreas. This report seeks to introduce the novel use of EUS-guided LA for left adrenal metastases from pancreatic adenocarcinoma. A 70-year-old female was referred to our hospital for dull abdominal pain and tiredness for 1 month. Computed tomography (CT) discovered a 1.0 × 1.7 cm mass in the area of the left adrenal gland. The lesion was highly suspicious for metastasis due to her history of pancreatic adenocarcinoma 1 year ago, which was removed through radical surgery. Intraoperative frozen-section pathology revealed a tumour invading the left adrenal gland. The left adrenal mass was clearly visualised on EUS and exhibited irregular hyper-enhancement during contrast. The tumour was successfully treated by four sessions of EUS-guided LA. After the procedure, symptomatic relief was achieved and remained. At the 4-month follow-up, contrast-enhanced CT revealed that the volume of the target was significantly decreased. Here, we introduced a new method for left adrenal metastasis using thermal ablation through EUS. As a potential alternative access to the percutaneous approach, EUS-guided LA may provide a minimally invasive treatment to relieve the tumour burdens and symptoms when applied accurately.

Bridge flap repair for central nasal dorsum defect
Abstract
Surgery of the nose to remove skin cancer often requires the use of local flaps. We present a defect after the extirpation of a previously incompletely excised infiltrative squamous cell carcinoma, which we repaired with a Bridge flap, a bipedicled and subcutaneous islanded flap whose excellent vascularity allows reliable reconstruction and rapid mobilisation, with dependable results.

HPV bei Oropharynxkarzinomen in der 8. Ausgabe der TNM-Klassifikation
Laryngo-Rhino-Otol
DOI: 10.1055/s-0043-123028
Die 8. Ausgabe der TNM-Klassifikation ist seit dem 01.01.2017 gültig und beinhaltet Veränderungen dieser Klassifikation für verschiedene Malignome. Solche Änderungen zeigen sich im Kopf-Hals-Bereich für Plattenepithelkarzinome des Oropharynx (OPC): es wird zwischen HPV-positiven und HPV-negativen Karzinomen unterschieden, um durch die daran adaptierte neue Stadieneinteilung die Prognose der Patienten mit OPC insgesamt besser abschätzen zu können. Die Anwendung der neuen TNM-Klassifikation beim HPV-positiven OPC führt in vielen Fällen zu einem signifikanten Downstaging von lokal fortgeschrittener (UICC III/IV) hin zu lokal begrenzter (UICC I/II) Erkrankung. Letzterem zugrundliegende Daten mit einem signifikanten Überlebensvorteil der Patienten mit HPV-positiven OPC entstammen bisher ausschließlich retrospektiven Analysen, die nicht dafür ausgelegt sind zu testen, ob deeskalierte Therapieregime den Überlebensvorteil dieser Patienten erhalten können. Dieser CME-Beitrag versucht Antworten auf offene Fragen hinsichtlich Pathologie, Tumorcharakteristik und Lebensstil-Faktoren zu geben, die für die Prognose dieser Patientenpopulation eine Rolle spielen. Nur die genaue Kenntnis aller Parameter, die die Überlebenszeiten von Patienten mit OPC beeinflussen und die präzise Interpretation vorliegender und noch zu erhebender Daten wird es ermöglichen, den Patienten entsprechend ihrem Risikoprofil die bestmögliche Therapie anzubieten und so das bestmögliche Behandlungsergebnis zu erzielen.

Dehiszenzsyndrom des oberen Bogengangs
Zusammenfassung
Einleitung
Das Bogengangsdehiszenzsyndrom („superior canal dehiscence syndrome", SCDS) ist eine relativ seltene neurotologische Erkrankung. Sie zeichnet sich durch ein heterogenes klinisches Bild aus. Kürzlich wurden vestibulär evozierte myogene Potenziale (VEMP) zur Diagnostik des SCDS etabliert. In der vorliegenden Arbeit wurde eine Fallserie von Patienten mit SCDS analysiert, mit einem Fokus auf den VEMP-Befunden.
Methoden
Vier Patienten mit SCDS wurden prospektiv mittels okulären VEMP (oVEMP) und zervikalen VEMP (cVEMP) untersucht. Dabei wurden die klinischen Befunde sowie die weiteren audiovestibulären Testergebnisse zusammengefasst und analysiert. Die diagnostische Genauigkeit der VEMP-Untersuchungen wurde evaluiert.
Ergebnisse
Die Erhöhung der oVEMP-Amplituden weist in dieser Fallserie eine Spezifität von 100 % auf. Bei allen Patienten fand sich eine normale kalorische Funktion sowie ein unauffälliger Kopfimpulstest. Zwei Patienten wiesen ein Tullio-Phänomen auf, bei 3 Patienten lag eine Autophonie vor. Die Schallleitungskomponente war bei keinem Patienten >10 dB. Ein Patient zeigte einen deutlichen Fremitusnystagmus. Bei allen Patienten zeigte sich in der Computertomographie eine knöcherne Dehiszenz des oberen Bogengangs.
Schlussfolgerung
Beim SCDS ergab sich in dieser Fallserie ein heterogenes Bild bei Anamnese und klinischer Untersuchung. Die oVEMP-Untersuchung jedoch erwies sich als der diagnostisch wertvollste Test. Darüber hinaus wird hier ein neues diagnostisches klinisches Zeichen beschrieben, der Fremitusnystagmus.

Is amalgamated ligno-bupivacaine an answer to complicated minor oral surgical anesthesia? A randomized split-mouth double-blind clinical trial
Abstract
Purpose
The purpose of this study was to find a suitable anesthetic combination for complicated and protracted minor oral surgical procedures.
Methods
Fifty patients with bilaterally impacted deep-seated mandibular third molars were included in this study and randomly divided on the basis of anesthetic used into two groups. Group A received 2% lignocaine with 1:200,000 adrenaline while in group B, amalgamated mixture of 2% lignocaine and 0.5% bupivacaine was used. The onset time, duration of anesthetic effect, supplementary injections, pain (during local anesthetic deposition, intra and postoperatively), and postoperative analgesia were the study parameters. Chi-square and unpaired t tests were used to compare means.
Results
The onset time in both the groups was comparable and showed statistically significant difference between the duration of anesthetic effect with notable requirement of supplemental anesthetic injections in group A (54%) (p < 0.05). Pain scores also revealed a statistically significant intergroup difference (p < 0.05). Requirement of postoperative analgesics was delayed in group B.
Conclusions
The amalgamated mixture of lignocaine and bupivacaine had equivocally rational onset and provided a more profound and in-depth anesthesia especially in complicated and protracted minor oral surgical procedures. Though this mixture is widely used in other surgical fields, its efficacy still remains unexploited and undocumented in oral and maxillofacial surgical procedures.

An Unusual Case of Pinna Squamous Cell Carcinoma Arising Shortly after Resection of Atypical Fibroxanthoma
Objective. To report a unique case of pinna squamous cell carcinoma (SCC) arising shortly after resection of atypical fibroxanthoma (AFX) at the same site. Case report. An 81-year-old gentleman presented with a nodular right pinna lesion. This was excised, and histology confirmed AFX. Ten weeks later, an ulcerative lesion appeared at the resection site. This was confirmed to be SCC. Comparative analysis revealed no morphological resemblance between the initial AFX and new SCC lesion, and there was no evidence of initial misdiagnosis. Conclusion. SCC is the most common cancer involving the pinna. Whilst prolonged sun exposure is an important risk factor for SCC, chronic inflammation and wounds are other potential sources. We postulate whether SCC could have arisen from the previous scar tissue in a manner similar to Marjolin's ulcer. This would be a highly unusual finding in the pinna and to our knowledge unprecedented in the English literature.

Outcomes after free tissue transfer for composite oral cavity resections involving skin
Abstract
Background
Resections involving oral cavity mucosa, bone, and skin present a unique challenge. Optimizing outcomes often requires technically demanding reconstruction. The purpose of this study is to evaluate outcomes of several reconstructive approaches for patients with composite through-and-through defects, with a focus on the osteocutaneous radial forearm free flap (RFFF).
Methods
We conducted a retrospective evaluation of the cohort of patients treated for composite through-and-through defects with cutaneous involvement who underwent free flap reconstruction from August 2012 through October 2015.
Results
Seventeen patients received a single flap (12 cases of osteocutaneous RFFF), whereas 10 patients underwent a combination of flaps. Complication rates and functional outcomes were favorable in patients who underwent osteocutaneous RFFFs. The supraclavicular artery island flap (SCAIF) was used as a second flap in 3 cases.
Conclusion
The osteocutaneous RFFF provides a valuable reconstructive option for complex composite resection defects involving skin. When 2 flaps are required, the SCAIF is a viable alternative to a second free flap or pectoralis flap.

Immunocompromised patients with metastatic cutaneous nodal squamous cell carcinoma of the head and neck: Poor outcome unrelated to the index lesion
Abstract
Background
Immunocompromised patients with metastatic cutaneous nodal head and neck squamous cell carcinoma (HNSCC) have worse outcomes compared to the immunocompetent. The purpose of this study was to investigate the characteristics of the primary cutaneous squamous cell carcinoma (SCC), nodal pathology, and outcome between these 2 groups.
Methods
Analysis of a prospective database was performed. A 2:1 pooled analysis selected 46 immunocompetent patients matched with 23 immunocompromised patients. Overall survival (OS) and relapse-free survival (RFS) were calculated using the Kaplan-Meier method.
Results
No significant difference was found in the primary tumor characteristics between the 2 groups. In the immunocompromised group, RFS (hazard ratio [HR] 2.70; P = .01) and OS (HR 2.32; P = .04) were significantly worse. Extracapsular spread was present in 100% of the immunocompromised patients.
Conclusion
No significant difference was identified in the primary cutaneous SCC between the immunocompetent and immunocompromised patients. Immunosuppression predicted worse outcome.

Obviating the need for sternotomy: Safety and effectiveness of microdebrider use for retrosternal goiter
Abstract
Background
Most retrosternal goiter surgical removal can be performed via a transcervical approach. However, it is often a challenging procedure, which might include sternotomy.
Methods
We describe a surgical technique using a microdebrider for intracapsular volume reduction that precedes an extracapsular thyroidectomy, thereby avoiding the need for sternotomy, with decreased morbidity and risk. The procedure is described in detail with 2 representative cases and a summary of our experience in 26 cases.
Results
Twenty-six patients with retrosternal goiters are included in our cohort. None of the patients needed a sternotomy, and no major or permanent complications occurred. The average length of hospital stay was 4.30 days after total thyroidectomy and 2.57 days after hemithyroidectomy.
Conclusion
The use of a microdebrider for intracapsular volume reduction thyroidectomy is extremely helpful for transcervical removal of retrosternal goiters in selected cases, and avoids the need for sternotomy, which is especially beneficial in elderly patients, and those with comorbidities for whom sternotomy should be avoided.

Predictors of clinical-pathologic stage discrepancy in oral cavity squamous cell carcinoma: A National Cancer Database study
Abstract
Background
Few studies have examined the frequency and survival implications of clinicopathologic stage discrepancy in oral cavity squamous cell carcinoma (SCC).
Methods
Oral cavity SCC cases with full pathologic staging information were identified in the National Cancer Database (NCDB). Clinical and pathologic stages were compared. Multivariate logistic regressions were performed to identify factors associated with stage discrepancy.
Results
There were 9110 cases identified, of which 67.3% of the cases were stage concordant, 19.9% were upstaged, and 12.8% were downstaged. The N classification discordance (28.5%) was more common than T classification discordance (27.6%). In cases of T classification discordance, downstaging is more common than upstaging (15.4% vs 12.1% of cases), but in cases of N classification discordance, the reverse is true; upstaging is much more common than downstaging (20.1 vs 8.4% of cases).
Conclusion
Clinicopathologic stage discrepancy in oral cavity SCC is a common phenomenon that is associated with a number of clinical factors and has survival implications.

Lymph node ratio as a prognostic factor in metastatic cutaneous head and neck squamous cell carcinoma
Abstract
Background
The prognostic impact of the size and number of nodal metastases in head and neck cutaneous squamous cell carcinoma (SCC) is well established. The purpose of this study was to validate the prognostic significance of the lymph node ratio in metastatic head and neck cutaneous SCC.
Methods
A retrospective review of 326 patients with head and neck cutaneous SCC with parotid and/or cervical nodal metastases was performed. The primary endpoints were overall survival (OS) and disease-free survival (DFS). The minimal-P approach was used to investigate the optimal lymph node ratio threshold.
Results
Our data included 77 recurrences and 101 deaths. A lymph node ratio of 6% was a significant predictor of shorter DFS (hazard ratio [HR] 1.62; 95% confidence interval [CI] 1.11-2.38; P = .01) and OS (HR 1.63; 95% CI 1.03-2.58; P = 0.04) on multivariable analysis.
Conclusion
The lymph node ratio is an independent prognosticator of survival outcomes in patients presenting with metastatic head and neck cutaneous SCC. A lymph node ratio >6% is a significant threshold to categorize patients into low and high risk.

Biosimilars: what the dermatologist should know
Abstract
Biosimilars are highly similar versions of approved branded biologics. In contrast to generics, which are identical copies of the originator medicines, biosimilars are considered unique but related molecules that differ from the originator reference product as well as from each other. Owing to the complexity of biologic medicines, such as therapeutic monoclonal antibodies, minor differences between biosimilars and the reference products are acceptable provided these differences do not result in any clinically meaningful differences in safety or efficacy. In addition, minor changes in structure and function may occur over time in originator biologic products as a result of alterations in production materials (e.g., cell lines), processes, or conditions. The developmental process for biosimilars focuses on a 'totality of evidence' approach that emphasizes a stepwise investigational process, including comprehensive structural, functional, pharmacologic, and clinical assessment for similarity. The goal of the phase 3 clinical development program for a biosimilar is not to establish efficacy, per se, but to demonstrate that there are no clinically meaningful differences between the proposed biosimilar and the reference product. The requirement to show clinical similarity informs biosimilar study design, including the selection of the patient population, disease state (indication), study endpoints, and statistical methods. Based on the clinical trials results in a representative patient population, results may be extrapolated to other indications provided scientific justification is demonstrated based on, among other things, similar mechanism of action in the extrapolated indications. This review presents the current state of knowledge with respect to biosimilars. We aim to provide the practicing clinician with a working knowledge of biosimilars as well as provide some practical guidance on their use and potential benefits in treating dermatologic diseases.

Olfactory dysfunction and cognition among older adults in the United States
Background
In this work we assess the association between olfactory dysfunction and cognition in a nationally representative sample of older adults in the United States.
Methods
Participants aged ≥60 years (n = 1236) from the 2013–2014 National Health and Nutritional Examination Survey underwent both olfactory and cognitive testing. Olfaction was assessed by both objective test (8-odor Pocket Smell Test: smell impairment defined as score ≤2) and self-report. Cognitive assessment consisted of the Digit Symbol Substitution Test (DSST), the Animal Fluency Test, and the Consortium to Establish a Registry for Alzheimer's Disease (CERAD). Regression models were used to examine the association between olfaction and cognition while adjusting for demographics, cardiovascular factors, and associated medical history.
Results
The prevalence of smell impairment in US older adults was 18.0% (95% confidence interval [CI], 14.0-22.0%) and 22.0% (95% CI, 18.5-25.6%) based on objective smell test and self-report, respectively. In a multivariate model adjusted for relevant factors, low smell test scores were consistently associated with low scores on cognitive assessments, with a DSST score difference of −1.5 (95% CI, −2.2 to −0.8), Animal Fluency Test score difference of −0.4 (95% CI, −0.7 to −0.1), and CERAD Word List score difference of −0.4 (95% CI, −0.6 to −0.2) per 1-point decrease in smell test score. There was no association between self-reported smell impairment and cognition.
Conclusion
Objectively measured olfactory dysfunction is independently associated with cognitive impairment. These findings are consistent with previous studies and suggest the utility of objective olfactory tests as an indicator for cognitive impairment as compared with self-reported olfactory dysfunction, which is an uncertain indicator.

Concentration of filaggrin monomers, its metabolites and corneocyte surface texture in individuals with a history of atopic dermatitis and controls
Abstract
Background
Atopic dermatitis (AD) is characterized by skin barrier dysfunction. Notably, a high number of nano-scale protrusions on the surface of corneocytes, which can be expressed by the Dermal Texture Index (DTI), was recently associated with pediatric AD, loss-of-function mutations in filaggrin gene (FLG), and reduced levels of natural moisturizing factors (NMF). No study has so far examined the association between these parameters and monomeric filaggrin levels in adults.
Objective
To determine DTI, monomeric filaggrin and NMF in healthy controls and a group of patients with controlled dermatitis.
Methods
A total of 67 adults (20 healthy controls and 47 dermatitis patients) were included. In the patient population, a personal history of AD was diagnosed by the U.K. Working Party's Diagnostic Criteria. All participants were tested for FLG mutations (R501X, 2282del4, R2447X). Transepidermal water loss, monomeric filaggrin, DTI and NMF were measured.
Results
In the patient population, 78.7% (37/47) had a history of AD and 59.5% (28/47) had FLG mutations. Patients had significantly higher levels of DTI and significantly lower levels of monomeric filaggrin and NMF compared to the 20 healthy controls. Among patients, reduced level of monomeric filaggrin and NMF correlated with the presence of FLG mutations and clinical phenotypes such as xerosis, palmar hyperlinearity and AD. Among healthy controls, DTI was significantly higher in the oldest age group compared to the two younger age groups.
Conclusion
A significant difference in DTI, monomeric filaggrin and NMF levels was found when comparing dermatitis patients with healthy controls. These findings suggest that even mild dermatitis or non-visible inflammation has a significant and negative effect on the skin barrier as inflammation is known to reduce filaggrin levels. DTI was significantly increased in aged individuals in the healthy control group, suggesting a gradual change in corneocyte morphology with age.

Intraoperative Brief Electrical Stimulation of the Spinal Accessory Nerve (BEST SPIN) for prevention of shoulder dysfunction after oncologic neck dissection: a double-blinded, randomized controlled trial
Abstract
Background
Shoulder dysfunction is common after neck dissection for head and neck cancer (HNC). Brief electrical stimulation (BES) is a novel technique that has been shown to enhance neuronal regeneration after nerve injury by modulating the brain-derived neurotrophic growth factor (BDNF) pathways. The objective of this study was to evaluate the effect of BES on postoperative shoulder function following oncologic neck dissection.
Methods
Adult participants with a new diagnosis of HNC undergoing Level IIb +/− V neck dissection were recruited. Those in the treatment group received intraoperative BES applied to the spinal accessory nerve (SAN) after completion of neck dissection for 60 min of continuous 20 Hz stimulation at 3-5 V of 0.1 msec balanced biphasic pulses, while those in the control group received no stimulation (NS). The primary outcome measured was the Constant-Murley Shoulder (CMS) Score, comparing changes from baseline to 12 months post-neck dissection. Secondary outcomes included the change in the Neck Dissection Impairment Index (ΔNDII) score and the change in compound muscle action potential amplitude (ΔCMAP) over the same period.
Results
Fifty-four patients were randomized to the treatment or control group with a 1:1 allocation scheme. No differences in demographics, tumor characteristics, or neck dissection types were found between groups. Significantly lower ΔCMS scores were observed in the BES group at 12 months, indicating better preservation of shoulder function (p = 0.007). Only four in the BES group compared to 17 patients in the NS groups saw decreases greater than the minimally important clinical difference (MICD) of the CMS (p = 0.023). However, NDII scores (p = 0.089) and CMAP amplitudes (p = 0.067) between the groups did not reach statistical significance at 12 months. BES participants with Level IIb + V neck dissections had significantly better ΔCMS and ΔCMAP scores at 12 months (p = 0.048 and p = 0.025, respectively).
Conclusions
Application of BES to the SAN may help reduce impaired shoulder function in patients undergoing oncologic neck dissection, and may be considered a viable adjunct to functional rehabilitation therapies.

Postmenopausaler Lichen planopilaris alias fibrosierende frontotemporale Alopezie Kossard
Zusammenfassung
Der postmenopausale Lichen planopilaris (PLPP) alias fibrosierende frontotemporale Alopezie Kossard (FFAK) ist eine nicht seltene entzündliche Erkrankung der Kopfhaut und betrifft etwa 5 % der Patienten an spezialisierten Haarzentren. Die allgemeine Inzidenz des sporadischen Vorkommens liegt vermutlich bei knapp 1 % in der älteren, vorrangig weiblichen Allgemeinbevölkerung. Da die Erkrankung oft nicht diagnostiziert wird, ist sie statistisch wahrscheinlich unterrepräsentiert. Sie kommt speziell bei Frauen betont in der 6. und 7. Lebensdekade postmenopausal vor (um 90 %), etwa in 10 % aber auch prämenopausal. Bei Männern ist sie nur in Einzelfällen dokumentiert. Die Folge ist ein bleibender vernarbender Haarausfall, betont am vorderen Haaransatz mit Rückwärtsbewegung des Ansatzes, begleitet von einem regelhaften, typischen Verlust auch der Augenbrauen. Die Erkrankung führt daher bei Betroffenen oft zu erheblichen psychischen Belastungen und sozialen Ängsten. Hieraus leitet sich das zwingende Erfordernis ab, Therapiekonzepte evidenzbasiert zu entwickeln. Während zahlreiche retrospektive Fallserien die Phänomenologie der FFAK sehr gut charakterisiert haben, fehlen bis heute randomisierte kontrollierte Studien zur evidenzbasierten Therapie. Wir stellen hier den Homburger evidenzorientierten Therapiealgorithmus vor, der so weit an Fallserienevidenzen orientiert ist, dass er a) als Therapieanleitung für die Praxis dienen und b) als Arbeitsgrundlage herangezogen werden kann, um zukünftig belastbare, auf Studienevidenz basierte Daten zu erarbeiten. Der Beitrag enthält detaillierte praktische Hinweise zur Fotodokumentation, zur Biopsieentnahme und histologischen Aufarbeitung bis hin zur praktischen Durchführung etwa der intraläsionalen Steroidtherapie sowie Hinweise zu Auswahlkriterien geeigneter Systemtherapien.

Severe Drug-Induced Agranulocytosis Successfully Treated with Recombinant Human Granulocyte Colony-Stimulating Factor
When elderly patients are prescribed many different medications, the risk for developing serious adverse events should be kept in mind. One of these adverse events is agranulocytosis, which, although rare, can be life-threatening if left untreated. The majority of agranulocytosis cases are caused by drugs, including antibiotics. Here, we report a case of severe agranulocytosis in a 96-year-old woman following antibiotic therapy which was successfully managed using recombinant human granulocyte colony-stimulating factor (rhG-CSF) and the appropriate choice of antibiotics to treat her concomitant infection.

The marginal fit of lithium disilicate crowns: Press vs. CAD/CAM
Abstract: This study aimed to compare the vertical marginal gap of teeth restored with lithium disilicate crowns fabricated using CAD/CAM or by pressed ceramic approach. Twenty mandibular third molar teeth were collected after surgical extractions and prepared to receive full veneer crowns. Teeth were optically scanned and lithium disilicate blocks were used to fabricate crowns using CAD/CAM technique. Polyvinyl siloxane impressions of the prepared teeth were made and monolithic pressed lithium disilicate crowns were fabricated. The marginal gap was measured using optical microscope at 200× magnification (Keyence VHX-5000, Japan). Statistical analysis was performed using Wilcoxon test. The lithium disilicate pressed crowns had significantly smaller (p = 0.006) marginal gaps (38 ± 12 μm) than the lithium disilicate CAD/CAM crowns (45 ± 12 μm). This research indicates that lithium disilicate crowns fabricated with the press technique have measurably smaller marginal gaps compared with those fabricated with CAD/CAM technique within in vitro environments. The marginal gaps achieved by the crowns across all groups were within a clinically acceptable range.

Oral health related quality of life among pregnant women: a randomized controlled trial
Abstract: The aim of the present study was to compare negative impacts of oral conditions in Oral Heath Related Quality of Life (OHRQoL) assessed by the Oral Health Impact Profile-14 (OHIP-14) scores in pregnant women receiving or not comprehensive periodontal treatment. This randomized controlled clinical trial included pregnant women aged between 18 and 35 years old. Participants were randomized in a test group with 96 and a control group with 114 women. Patients in the test group received comprehensive periodontal treatment, supra and subgingival scaling and root-planning and periodontal maintenance appointments. The OHIP-14 was applied before and after treatment. The primary outcome was changes in OHIP-14 scores after follow-up period. The impact of having received or not comprehensive periodontal treatment on the change of the OHIP-14 scores was also investigated. Both groups showed significant reduction in OHIP-14 scores and effect size for the test group was 0.60 and 0.36 for the control group. Multinomial logistic regression analysis showed that participants of the control group had 5.9-fold odds (CI 95% 1.88-18.52) of worsening in OHIP-14 scores and their perception of oral conditions in relation to test group. Comprehensive periodontal treatment during pregnancy can reduce the negative impacts in OHRQoL.
