Radiation effects in head and neck and role of hyperbaric oxygen therapy: An adjunct to management.

Background: Radiotherapy is considered an essential treatment modality in cancers, especially head and neck cancers. Radiotherapy can be given as a definitive, supportive, or adjuvant therapy for various cancers. Radiation damage is an avoidable complication in many patients, after or during radiotherapy. It may be either dose-related, duration-related, or frequency-related. The effects of radiation damage are mainly caused by ischemic necrosis, and once settled it is difficult to manage due to the low vascularity of the affected area. Aim: To find out the effectiveness of hyperbaric oxygen therapy (HBOT) in the management of radiation damage in the head and neck region. Materials and Methods: Retrospective data of patients attending the HBOT clinic for postradiotherapy changes were recorded in an Excel sheet and analyzed in this study. Statistical analysis was done. Result: Our study showed that HBOT is effective in postradiation trismus, xerostomia, discharge, foul smell, discharging sinus, etc., However, it was not found to be significant in the closure of fistula with exposed bone. Conclusion: HBOT is an effective adjunct modality for the management of postradiation changes in the head and neck region.

Epidemiology of Odontogenic Sinusitis.

Odontogenic sinusitis (ODS) is more common than historically thought, representing 25% to 40% of all maxillary sinusitis. Due to a lack of widely accepted diagnostic criteria and a specific international diagnostic code, a true overall prevalence is unknown. ODS may be caused by either a multitude of infectious dental pathologies or complications after dental procedures. The most common dental etiologies causing ODS are apical periodontitis (endodontic) and oroantral communication or fistula after dental extraction. Less commonly, ODS can evolve after dental implant or maxillary sinus bone grafting surgeries, infection of odontogenic cysts, or advanced periodontitis.

A novel metric-based approach of scoring early host immune response from oro-nasopharyngeal swabs predicts COVID-19 outcome.

Unpredictable fatal outcome of COVID-19 is attributed to dysregulated inflammation. Impaired early adaptive immune response leads to late-stage inflammatory outcome. The purpose of this study was to develop biomarkers for early detection of host immune impairment at first diagnosis from leftover RNA samples, which may in turn identify high risk patients. Leftover RNA samples of COVID-19 patients at first diagnosis were stored. Following prospective follow-up, the samples were shorted and categorized into outcome groups. Impaired adaptive T cell response (severity score) and Impaired IL-10 response (undetectable IL-10 in the presence of high expression of a representative interferon response gene) were determined by RT-PCR based assay. We demonstrate that a T cell response based 'severity score' comprising rational combination of Ct values of a target genes' signature can predict high risk noncomorbid potentially critical COVID-19 patients with a sensitivity of 91% (95% CI 58.7-99.8) and specificity of 92.6% (95% CI 75.7-99) (AUC:0.88). Although inclusion of comorbid patients reduced sensitivity to 77% (95% CI 54.6-92.2), the specificity was still 94% (95% CI 79.8-99.3) (AUC:0.82). The same for 'impaired IL-10 response' were little lower to predict high risk noncomorbid patients 64.2% (95% CI 35.1-87.2) and 82% (95% CI 65.5-93.2) respectively. Inclusion of comorbid patients drastically reduce sensitivity and specificity51.6% (95% CI 33.1-69.8) and 80.5% (95% CI 64.0-91.8) respectively. As best of our knowledge this is the first demonstration of a metric-based approach showing the 'severity score' as an indicator of early adoptive immune response, could be used as predictor of severe COVID-19 outcome at the time of first diagnosis using the same leftover swab RNA. The work flow could reduce expenditure and reporting time of the prognostic test for an earliest clinical decision ensuring possibility of early rational management.

Persistent Idiopathic Dentoalveolar Pain in a Patient With Implant Placement: A Case Report.

Persistent idiopathic dentoalveolar pain (PIDAP) is a type of disease that, despite affecting thousands of people globally, negatively impacts patients' quality of life because of its unknown cause. Notably, the disease has a high prevalence rate and is primarily prone to middle-aged and senior individuals. Efforts have been made to gain the understanding needed for the accurate diagnosis and prompt treatment of PIDAP cases. This case report discusses the challenges faced in diagnosing and managing PIDAP after dental implants. The present study involved the case of a 62-year-old male patient, previously operated on for an implant at position #11, who suffered from chronic pain but no specific cause could be identified. We used an evaluation strategy to gain insights into the patient's illness, including antibiotic treatment, crown replacement, and continued pain. We prescribed nortriptyline 10 mg, and there was an improvement. This finding suggests that nortriptyline 10 mg QHS eliminates chronic pain.

Prognostic factors for tube feeding in type I SMA patients treated with disease-modifying therapies: a cohort study.

The aim of this study was to assess the need for tube feeding in a cohort of treated infants with type I SMA and to identify predictive factors. All patients were classified at baseline, when treatment started, and at follow-up according to their functional level and the need for tube feeding. Fisher's exact test was used to examine the associations between the outcome at the last follow-up and SMA type, SMN2 copy number, and baseline nutritional status. ANOVA was performed to compare CHOP INTEND scores and age at treatment initiation with outcomes. The cohort includes 75 type I SMA infants treated between 0.1 and 5 years of age. At the last follow-up, 34 had no need for tube feeding, 9 had tube feeding but were also able to be fed by mouth, and 32 had tube feeding and were unable to be fed by mouth. Thirty of the 41 infants with tube feeding at follow-up already had feeding difficulties when treatment was started. The need for tube feeding at follow-up was associated with the level of feeding involvement at baseline and with CHOP INTEND scores [p < 0.001] but not with SMN2 copy number, SMA type 1 subtypes or age at treatment. The results of this study suggest that the need for tube feeding is not frequent in treated infants with type I SMA and, when occurring, can be predicted by the level of feeding involvement and low CHOP INTEND scores at baseline. What is Known: • The advent of disease-modifying therapies is increasingly changing the approach to swallowing and nutritional management in type I SMA. • Clinical trials and real-world data using all three disease-modifying therapies report a rather wide variability of feeding outcome and need for tube feeding that is often related to different cohorts that makes comparison between studies very difficult. What is New: • The real-world findings of this study, including all the children treated since treatments became available, confirmed that the need for tube feeding is not an invariable finding. • The level of feeding involvement at baseline appears to be a reliable prognostic indicator of bulbar outcome. • The results highlight the need for interventional studies with structured Speech and Language Therapist protocols that will help to better understand the extent to which bulbar function can be maintained or regained even in children requiring tube feeding.

Structured Routine Use of Styletubation for Oro-Tracheal Intubation in Obese Patients Undergoing Bariatric Surgeries-A Case Series Report.

The aim of this case series report is to provide a new topical view of styletubation (video intubating stylet technique) in obese patients undergoing bariatric surgeries. In contrast to various conventional direct laryngoscopes (DLs), videolaryngoscopes (VLs) have been applied in such obese populations with potentially difficult airway complications. The safety and effectiveness of VLs have been repeatedly studied, and the superiority of VLs has then been observed in and advocated for routine use. In this article, among our vast use experiences with styletubation (more than 54,998 patients since 2016) for first-line routine tracheal intubation, we present the unique experience to apply the styletubation technique in obese patients undergoing bariatric surgery. Consistent with the experiences applied in other patient populations, we found the styletubation technique itself to be swift (the time to intubate from 5 s to 24 s), smooth (first-attempt success rate: 100%), safe (no airway complications), and easy (high subjective satisfaction). The learning curve is steep, but competency can be enhanced if technical pitfalls can be avoided. We, therefore, propose that the styletubation technique can be feasibly and routinely applied as a first-line airway modality in obese patients undergoing bariatric surgery.

Effect of suckler cow breed type and parity on the development of the cow-calf bond post-partum and calf passive immunity.

BACKGROUND: Development of the cow-calf bond post-partum and passive immunity of calves from spring-calving beef × beef (B×B) and beef × dairy (B×D) cow genotypes was determined using primiparous and multiparous (Experiment 1), and primiparous and second-parity (Experiment 2) animals. In Experiment 1, calves either suckled colostrum naturally ('natural-suckling') (n = 126), or were fed colostrum, using an oesophageal-tube ('artificially-fed') (n = 26), from their dam within 1-h post-partum. In Experiment 2, all calves (n = 60) were artificially-fed colostrum from their dam. Prior to colostrum suckling/feeding, colostrum was sampled for IgG analysis. The cow-calf bond was assessed using CCTV recordings during the first 4-h post-partum. Calves were blood sampled at 48-h post-partum to determine IgG and total protein (TP) concentrations, and zinc sulphate turbidity (ZST) units. RESULTS: There was no difference (P > 0.05) in cow licking behaviours and calf standing and suckling behaviours between the genotypes, except in Experiment 2 where B×D calves had more attempts to suckle before suckling occurred (P ≤ 0.05) compared to B×B calves. In Experiment 1, multiparous cows licked their calves sooner (P ≤ 0.05) and for longer (P < 0.01), and their calves had fewer attempts to stand (P < 0.001), stood for longer (P = 0.05), and had fewer attempts to suckle before suckling occurred (P < 0.001) than primiparous cows; there was no parity effect on cow-calf behaviour in Experiment 2. Colostrum IgG concentrations and measures of calf passive immunity did not differ (P > 0.05) between the genotypes in either Experiment. In Experiment 1, colostrum IgG concentrations were greater (P ≤ 0.05) in multiparous compared to primiparous cows and their calves had superior (P ≤ 0.05) passive immunity; no effect of parity was found in Experiment 2. Passive immunity did not differ (P > 0.05) between suckled and artificially-fed calves in Experiment 1. CONCLUSIONS: Cow genotype had little effect on cow-calf behaviours, but under 'natural-suckling' conditions primiparous cows expressed maternal inexperience and their calves were less vigorous than multiparous cows. Colostrum IgG concentration and calf passive immunity measures were unaffected by genotype, but under 'natural-suckling' conditions calves from primiparous cows had lower passive immunity.

Development and validation of a nomogram for tracheotomy decannulation in individuals in a persistent vegetative state: A multicentre study.

BACKGROUND: Decannulation for people in a persistent vegetative state (PVS) is challenging and relevant predictors of successful decannulation have yet to be identified. OBJECTIVE: This study aimed to explore the predictors of tracheostomy decannulation outcomes in individuals in PVS and to develop a nomogram. METHOD: In 2022, 872 people with tracheostomy in PVS were retrospectively enrolled and their data was randomly divided into a training set and a validation set in a 7:3 ratio. Univariate and multivariate regression analyses were performed on the training set to explore the influencing factors for decannulation and nomogram development. Internal validation was performed using 5-fold cross-validation. External validation was performed using receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA) on both the training and validation sets. RESULT: Data from 610 to 262 individuals were used for the training and validation sets, respectively. The multivariate regression analysis found that duration of tracheostomy tube placement≥30 days (Odds Ratio [OR] 0.216, 95 % CI 0.151-0.310), pulmonary infection (OR 0.528, 95 %CI 0.366-0.761), hypoproteinemia (OR 0.669, 95 % CI 0.463-0.967), no passive standing training (OR 0.372, 95 % CI 0.253-0.547), abnormal swallowing reflex (OR 0.276, 95 % CI 0.116-0.656), mechanical ventilation (OR 0.658, 95 % CI 0.461-0.940), intensive care unit (ICU) duration>4 weeks (OR 0.517, 95 % CI 0.332-0.805), duration of endotracheal tube (OR 0.855, 95 % CI 0.803-0.907), older age (OR 0.981, 95 % CI 0.966-0.996) were risk factors for decannulation failure. Conversely, peroral feeding (OR 1.684, 95 % CI 1.178-2.406), passive standing training≥60 min (OR 1.687, 95 % CI 1.072-2.656), private caregiver (OR 1.944, 95 % CI 1.350-2.799) and ICU duration<2 weeks (OR 1.758, 95 % CI 1.173-2.634) were protective factors conducive to successful decannulation. The 5-fold cross-validation revealed a mean area under the curve of 0.744. The ROC curve C-indexes for the training and validation sets were 0.784 and 0.768, respectively, and the model exhibited good stability and accuracy. The DCA revealed a net benefit when the risk threshold was between 0 and 0.4. CONCLUSION: The nomogram can help adjust the treatment and reduce decannulation failure. REGISTRATION: Clinical registration is not mandatory for retrospective studies.

Prevalence and influencing factors of malnutrition in stroke patients with bulbar paralysis: a cross-sectional study in China.

Background: Although malnutrition has been shown to influence the clinical outcomes of Stroke Patients with Bulbar Paralysis (SPBP), the prevalence and influencing factors have yet to be uncovered. Objective: This study aims to assess the current prevalence and factors associated with malnutrition in SPBP. Methods: A multicenter cross-sectional investigation was conducted among SPBP in China from 2019 to 2021. Information was collected on basic information, health condition, diagnosis, treatment, neurological function, activities of daily living, swallowing function, and nutritional status. A multivariable logistic regression model was used to identify the factors that influenced nutritional status. ROC analysis was used to assess the predictive value of each independent influencing factor and the logit model. Results: In total, 774 SPBP were enrolled, and the prevalence of malnutrition was 60.59%. Pulmonary infection [aOR:2.849, 95%CI: (1.426, 5.691)], hemoglobin [aOR: 0.932, 95%CI: (0.875, 0.982)], serum albumin [aOR: 0.904, 95%CI: (0.871, 0.938)], total protein [aOR: 0.891, 95%CI: (0.819, 0.969)], prealbumin [aOR: 0.962, 95%CI: (0.932, 0.993)], and National Institute of Health Stroke Scale (NIHSS) scores [aOR: 1.228, 95%CI: (1.054, 1.431)] were independent factors associated with malnutrition in SPBP. ROC analysis revealed that the logit model had the best predictive value [area under the curve: 0.874, 95% CI: (0.812, 0.936); specificity: 83.4%; sensitivity: 79.3%; p < 0.05]. Subgroup analysis showed that the nutritional status in dysphagic SPBP was additionally influenced by swallowing function and nutrition support mode. Conclusion: The prevalence of malnutrition in SPBP was 60.59%. Pulmonary infection, hemoglobin level, and NIHSS score were the independent factors associated with malnutrition. Swallowing function and nutrition support mode were the factors associated with malnutrition in dysphagic SPBP.

Hirudin enhances perforator flap survival: Clinical application report and mechanistic exploration.

BACKGROUND AND PURPOSE: Hirudin, a potent anticoagulant, is used in traditional Chinese medicine (TCM) to treat thrombotic conditions and prevent postoperative thrombosis. Coagulation-related vascular complications are a common cause of perforator flaps failure. This study explores hirudin's potential to enhance flap growth by mitigating coagulation-related issues. MATERIALS AND METHODS: Patients were divided into GroupⅠ(hirudin group) and GroupⅡ(control). Laboratory tests covered red blood cell count (RBC), hematocrit (HCT), platelet count (PLT), monocyte count (MONO), prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB), and D-Dimer. Clinical parameters, including capillary refill time (CRT), flap swelling, and survival status, were evaluated. Animal experiments used Sprague-Dawley (SD) rats to establish random skin flaps. The experimental side received hirudin injection, while the control side received saline. Flaps were photographed to calculate survival rate, and CD31 immunohistochemical (IHC) analysis was performed to calculate microvessel density (MVD). RESULTS: The study, with 29 patients, found significant CRT differences between groups on postoperative days 2 and 6 (p = 0.027; p = 0.019), favoring GroupⅠ. Swelling severity varied significantly over time; GroupⅡhad more pronounced swelling. GroupⅠshowed superior flap growth with fewer complications, statistically significant (p = 0.033). Specific lab indicators (MONO, PT, and FIB) were significant at certain times. In animal experiments, the experimental side consistently had higher flap survival and slightly increased CD31 expression at various times, with higher MVD on days 2 and 6. CONCLUSIONS: Hirudin enhances flap survival through diverse mechanisms, supporting its role as a complementary approach in perforator flap surgeries.

Unraveling the Genetic Tapestry: A Case Report on Oro-Facial-Digital Syndrome's Rare Features Across Generations in a Familial Trilogy.

Oro-facial-digital syndrome, specifically Mohr syndrome, is an uncommon genetic disorder characterized by predominant oro-facial anomalies and polysyndactyly. While typically associated with autosomal recessive and X-linked dominant inheritance patterns, this case presents an autosomal dominant mode of transmission. This report documents the clinical presentation of three individuals, a 12-year-old male child and two females, 10-year-old and eight-year-old, who have inherited the disorder from their ancestors. The observed features include post-axial polysyndactyly in both upper and lower limbs, with the male child exhibiting additional manifestations of strabismus and knee joint defects. Symptomatic management is pursued due to the absence of complications, with surgical interventions and subsequent cosmetic repairs planned for all three children. Post-surgical physiotherapy is scheduled as part of their comprehensive treatment plan. The prognosis for this disorder is generally favorable, with a complete recovery anticipated and no complications expected.

Treatment of Odontogenic Maxillary Sinusitis with the Use of Growth Factors in Advanced Platelet-Rich Fibrin for Immediate Closure of Oro-Antral Communication: A Case Report.

Chronic odontogenic maxillary sinusitis (COMS), a prolonged inflammation of the maxillary sinus lasting over 12 weeks, is often a result of periapical lesions, marginal periodontitis, and complications like oro-antral communication (OAC) and fistula (OAF). OAC, commonly emerging post-teeth extraction in the lateral maxilla, lacks documented treatments using advanced platelet-rich fibrin (A-PRF). This study evaluates A-PRF's efficacy in treating COMS and immediately sealing extensive OAC. A case of a 28-year-old male with COMS linked to a periapical lesion and supernumerary molars is presented. Treatment involved extracting specific teeth while preserving adjacent ones and using A-PRF for immediate OAC closure. A-PRF, enriched with growth factors, was pivotal in healing, showcasing enhanced tissue regeneration, pain reduction, and faster recovery. The findings suggest A-PRF as an effective adjunct in treating extensive OAC and COMS, proposing its inclusion in standard treatment protocols. This study underscores A-PRF's potential in improving outcomes for patients with COMS and related complications.

Conservative Management of Trigeminal Neuralgia and Degenerative Cervical Myelopathy: A Case Report.

It is hypothesized that degenerative cervical myelopathy (DCM) may induce or exacerbate trigeminal neuralgia (TN) through mechanisms such as direct compression of the spinal trigeminal tract, inflammation, or vascular issues, leading to ischemia within cervical segments C3-C4, where the spinal trigeminal nucleus extends. Here, we report the potential therapeutic impact of chiropractic treatment in a 55-year-old female with TN resistance to medical therapy and DCM. The patient received targeted chiropractic care, consisting of high-velocity, low-amplitude (HVLA) spinal manipulation of the C3-C7 and T1-T4 vertebral segments to address joint dysfunction, coupled with intermittent mechanical cervical traction for 20-minute sessions, and focused radial shockwave therapy aimed at myofascial trigger points within the trapezius and levator scapulae muscles. After initiating the chiropractic care plan, the patient experienced a significant reduction in the frequency and severity of TN pain, which persisted throughout the treatment period. Notably, this alleviation in symptoms was maintained at the six-month follow-up, suggesting a sustained therapeutic effect rather than a transient improvement. The lasting nature of the pain reduction provides a compelling argument for the long-term benefits of chiropractic intervention in the management of TN, particularly in cases with concurrent DCM.

The influence of COVID-19 on temporo-mandibular disorders.

Temporomandibular disorders are multi-factorial conditions affected by psychological, biomechanical, and neuromuscular factors. Stress and anxiety experienced during the pandemic are capable of influencing and aggravating temporomandibular disorders and orofacial pain. The study aimed to analyze whether the coronavirus infection can directly affect these diseases. All participants were asked to complete the Pain Screener and Patients Health Questionnaire and were assigned to Group I: healthy participants and Group 2: participants with existing complaints. In group II participants filled the questionnaires twice the Temporomandibular Disorders Symptom Questionnaire and Graded Chronic Pain Scale. The first time to self-report the severity of chronic pain before COVID-19 (T1 timeline) and the second time- to self-report the level of pain after COVID-19 infection (T2 timeline). Totally 150 participants were included in the study. In group II the difference between T1 and T2 timeline was significant for the level of average pain (p = 0.022) and highest facial pain (p = 0.043); Difference in level of interference of daily activities (p > 0.05), recreational activities (p > 0.05) and ability to work (p > 0.05) was statistically not significant. Graded chronic pain status was the same "Grade I" for T1 and T2 timeline. There was no statistically significant difference in stress level between group I and II.

Pycnodysostosis: Characteristics of teeth, mouth and jaws.

OBJECTIVES: To describe the clinical and radiographic oro-dental characteristics of patients with pycnodysostosis (PDO). MATERIALS & METHODS: A short interview and clinical examination of seven patients with PDO were performed as well as assessment of the temporomandibular joints and masticatory muscles using the diagnostic criteria for temporomandibular disorders, DC-TMD form. A full set of records were taken including photos and intraoral scan. Finally, existing cone beam computed tomography (CBCT) images and radiographs were also studied. RESULTS: All patients presented with bimaxillary micrognathia, five had a convex profile, and two had a straight profile. In addition, posterior open bite, Angle Class III molar relation with accompanying anterior crossbite and a grooved median palate were common findings. No patient showed symptoms of temporomandibular disorder (TMD) apart from some clicking. Finally, the main radiographic findings were the obtuse mandibular angle, the frontal bossing, the elongation of the coronoid/condylar process and the presence of hypercementosis with obliterated pulp chambers. CONCLUSION: The examined patients with PDO were characterized by dental crowding, malocclusion (anterior crossbite, posterior open bite), hypercementosis, obliterated pulp chambers and deviations in mandibular morphology. In conclusion, patients with PDO have a specific need for dental and orthodontic monitoring with focus on crowding and posterior open bite. The patients will benefit from a long-term orthodontic plan including extractions.

How stroke-related dysphagia relates to quality of life: the mediating role of nutritional status and psychological disorders, and the moderating effect of enteral nutrition mode.

Background: Although stroke-related dysphagia has been shown to influence quality of life (QOL), the underlying mechanisms have yet to be uncovered. Objective: This study aims to investigate the mediating role of nutritional status and psychological disorders in the relationship between stroke-related dysphagia and QOL in stroke patients and explore the moderating effect of enteral nutrition mode. Methods: In 2022, A questionnaire survey using stratified random sampling was conducted on 5,322 stroke patients with dysphagia, including Functional Oral Intake Scale (FOIS), Swallowing Quality of Life Questionnaire, Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 (GAD-7) to assess dysphagia, QOL and psychological disorders, respectively, for each participant. Records of serum albumin, Hemoglobin, Total serum protein, serum prealbumin and Body mass index were enrolled to assess nutritional status. Results: FOIS demonstrated a significant positive predictive effect on QOL. Nutritional status and psychological disorders (PHQ-9 and GAD-7) mediated the relationship between FOIS and QOL. Nutritional status-psychological disorders showed a chain mediation effect in the relationship between FOIS and QOL. The moderating effect of enteral nutrition mode was observed. Conclusion: The mediating role of nutritional status and psychological disorders with moderating effect of enteral nutrition mode in the relationship between dysphagia and QOL in stroke patients was found.

Oro-facial function and quality of life in children and adolescents with large horizontal maxillary overjet-A case-control study.

BACKGROUND: Large horizontal maxillary overjet (overjet) is associated with reduced bite force (BF) and number of contacts, which influence the chewing effectivity (CE). Oral health, oro-facial function (OF) and malocclusion have great impact on psychological well-being and quality of life (QoL). OBJECTIVES: The aims of the study were to examine OF, temporomandibular disorders (TMD), BF, CE, QoL and well-being in children and adolescents with large overjet. METHODS: The study was a case-control study including healthy children with large overjet in the study group compared to a control group of healthy children with neutral occlusion, all 9-14 years old. OF was examined by use of Nordic Orofacial Test-Screening (NOT-S), Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) and registration of morphological and functional occlusion. QoL and well-being were examined using KIDSCREEN-10 and Strengths and Difficulties Questionnaire. RESULTS: The study and control groups included 37 and 32 participants, respectively. Significantly increased NOT-S score (p < .001) and reduced BF (p = .011), numbers of contacts (p < .001) and CE (p = .005) were found in the study group. BF, numbers of contacts and CE were negatively associated with erupting canines and premolars. No significant difference was found in age, gender, dental eruption, TMD diagnosis or QoL between the groups. Significantly increased emotional symptoms (p = .007), hyperactivity (p = .043) and total difficulties score (p = .009) were found in the study group. CONCLUSION: The study group showed higher NOT-S score and reduced BF, number of contacts and CE. No difference in QoL were found between the groups, although reduced well-being and increased emotional symptoms, hyperactivity and total difficulties were found in the study group.

Updated EUROCAT guidelines for classification of cases with congenital anomalies.

BACKGROUND: Precise and correct classification of congenital anomalies is important in epidemiological studies, not only to classify according to etiology but also to group similar congenital anomalies together, to create homogeneous subgroups for surveillance and research. This paper presents the updated EUROCAT (European surveillance of congenital anomalies) subgroups of congenital anomalies and the updated multiple congenital anomaly (MCA) algorithm and provides the underlying arguments for the revisions. METHODS: The EUROCAT methodology is described. In addition, we show how we validated the revised EUROCAT subgroups and MCA algorithm, which are both based on the International Classification of Diseases (ICD10/ICD9) codes. RESULTS: The updated EUROCAT subgroups and the updated MCA algorithm are described in detail and the updated version is compared to the previous versions. CONCLUSION: The EUROCAT subgroups and MCA algorithm provide a standardized and clear methodology for congenital anomaly research and epidemiological surveillance of congenital anomalies in order to facilitate the identification of teratogenic exposures and to assess the impact of primary prevention and prenatal screening policies. The EUROCAT subgroups and MCA algorithm are made freely available for other researchers via the EUROCAT Database Management Software.

Which method is successful in closureof acute oroantral communication? A retrospective study / ¿Qué método tiene éxito en el cierre de la comunicación oroantral aguda? Un estudio retrospectivo

Background: This study's purpose is to retrospectively evaluate the success of surgical methods used in treatingOroantral Communication (OAC).Material and Methods: This study was designed as a retrospective cohort study on patients who developed OACafter surgery maxillary posterior region. The records of patients previously treated with OAC were scannedthrough the hospital registry software. A data set was created by recording patients' age, gender, systemic dis-ease, etiological reasons, and surgical methods. The primary predictor variable was the surgical method usedto treat OAC. Other variables were age, gender, systemic disease and etiological reasons. The primary outcomewas oroantral fistula development after the first surgical intervention. The patients who were positive in clinicalexamination and Valsalva test on control days were considered unsuccessful. One-way analysis of variance andKruskal-Wallis tests were used for quantitative variables in more than two groups. Pearson chi-square test wasused to compare categorical data.Results: This retrospective cohort study was completed with 605 patients who met the study criteria among 95,883patients who underwent surgery in the maxillary posterior region. The incidence of OAC was 0.63%. The patientsconsisted of 238 female and 367 male patients. The mean age was 41.06±14.48 years. Buccal flap and Buccal FatPad methods were used most frequently in the treatment. While treatment was completed with the first surgicalintervention in 592 (97.85%) patients, OAF developed in 13 (2.15%) patients. No statistically significant relationexisted between surgical technique and OAF development (p>0.005). The success rate of the Buccal Flap methodwas 98.7%, and the Buccal Fat Pad method was 95.8%.(AU)

Parents and Provider Perspectives on the Return of Genomic Findings for Cleft Families in Africa.

BACKGROUND: Inadequate knowledge among health care providers (HCPs) and parents of affected children limits the understanding and utility of secondary genetic findings (SFs) in under-represented populations in genomics research. SFs arise from deep DNA sequencing done for research or diagnostic purposes and may burden patients and their families despite their potential health importance. This study aims to evaluate the perspective of both groups regarding SFs and their choices in the return of results from genetic testing in the context of orofacial clefts. METHODS: Using an online survey, we evaluated the experiences of 252 HCPs and 197 parents across participating cleft clinics in Ghana and Nigeria toward the return of SFs across several domains. RESULTS: Only 1.6% of the HCPs felt they had an expert understanding of when and how to incorporate genomic medicine into practice, while 50.0% agreed that all SFs should be returned to patients. About 95.4% of parents were willing to receive all the information from genetic testing (including SFs), while the majority cited physicians as their primary information source (64%). CONCLUSIONS: Overall, parents and providers were aware that genetic testing could help in the clinical management of diseases. However, they cited a lack of knowledge about genomic medicine, uncertain clinical utility, and lack of available learning resources as barriers. The knowledge gained from this study will assist with developing guidelines and policies to guide providers on the return of SFs in sub-Saharan Africa and across the continent.
