How Long Should We Keep Children’s Surgical Sites Dry? The Incidence of Infection and Dehiscence After Pediatric Office Procedures

Objective: Studies evaluating the relationship between bathing and adverse surgical site events are sparse. In this study, we examine the incidence of surgical site infection (SSI) and dehiscence in a cohort of pediatric patients who were allowed to bathe 24 hours after their office procedures. Methods: Pediatric patients who underwent office procedures by a single plastic surgeon from 2017 to 2021 were included. All patients were allowed to bathe 24 hours after their office-based skin procedure. Age, sex, procedure type, pre procedure diagnosis, relevant past medical history, instances of dehiscence, and SSI were recorded. Results: 738 pediatric patients were included. Median age was 3.3 years(range 2 months-7 years), 46% were male and 54% were female. The most common pre procedure diagnoses were branchial vestige (24%), melanocytic nevi (21%), polydactyly (15%), congenital non-neoplastic nevus (11%), cyst (9%), hypertrophic scar (8%), and hemangioma(5%). No patients received systemic antibiotics post-procedurally. Six instances of dehiscence were recorded, and no SSIs were seen in any of the 738 patients. Conclusions: The low dehiscence rate and lack of SSIs in our cohort supports the hypothesis that children can bathe normally 24 hours after office procedures without adverse consequences. This recommendation can reduce the burden of post procedure wound care by reducing the length of time patients have to modify their bathing routines.

Genetic stratification reveals COL4A variants and spontaneous remission in Egyptian children with proteinuria in the first 2 years of life.

The earlier the onset of proteinuria, the higher the incidence of genetic forms. Therefore, we aimed to analyse the spectrum of monogenic proteinuria in Egyptian children presenting at age <2 years. The results of 27-gene panel or whole-exome sequencing were correlated with phenotype and treatment outcomes in 54 patients from 45 families. Disease-causing variants were identified in 29/45 (64.4%) families. Mutations often occurred in three podocytopathy genes: NPHS1, NPHS2 and PLCE1 (19 families). Some showed extrarenal manifestations. Additionally, mutations were detected in 10 other genes, including novel variants of OSGEP, SGPL1 and SYNPO2. COL4A variants phenocopied isolated steroid-resistant nephrotic syndrome (2/29 families, 6.9%). NPHS2 M1L was the single most common genetic finding beyond the age of 3 months (4/18 families, 22.2%). Biopsy results did not correlate with genotypes (n=30). On renin-angiotensin-aldosterone system antagonists alone, partial and complete remission occurred in 3/24 (12.5%) patients with monogenic proteinuria each, whereas 6.3% (1/16) achieved complete remission on immunosuppression. Genotyping is mandatory to avoid biopsies and immunosuppression when proteinuria presents at age <2 years. Even with such a presentation, COL4A genes should be included. NPHS2 M1L was prevalent in Egyptian children (4 months-2 years) with proteinuria, demonstrating precision diagnostic utility.

GERD surgery in non-neurologic patients: Modified Laparoscopic Hill-Snow Repair is a valid alternative to Nissen fundoplication. Results of a 20 years of follow-up

Nowadays laparoscopic Nissen fundoplication represents the gold standard in surgical treatment of complicated Gastro-Esophageal-Reflux Disease (GERD), above all in cerebral palsy patients. In non-neurological patients without gastrostomy Nissen fundoplication can create some problems (gas bloat syndrome, dysphagia). Laparoscopic Hill-Snow repair is an established surgical alternative, but it is reported only in adult population. We describe our modification of Hill-Snow technique and our experience in a large series of non-neurological children in order to report its effectiveness and applicability in pediatric patients affected by complicated GERD. Between 2000 and 2022, 319 children underwent surgical correction of gastro-esophageal reflux at our Department. All were affected by complicated gastro-esophageal reflux unresponsive to PPI (Proton Pump Inhibitors). 251 underwent laparoscopic Nissen fundoplication; 68 non-neurological patients underwent laparoscopic Hill-Snow repair. Of these 68 children 48 were males (71%) and 20 females (29%); median age was 5years (3 months-11 years). Weight range was 4-37kg. 52 patients (76.5%) presented the following symptoms: retrosternal pain, dysphagia, regurgitation, coughing, failure to thrive, persisting reflux esophagitis. 16 (23.5%) had chronic respiratory problems (aspiration, apneic-spells, dysphagia, coughing, choking, gagging). For 8 (11.8%) symptoms were expression of chronic recurrent gastric volvulus. All underwent modified-laparoscopic-Hill-Snow repair. Contrast study showed sliding hiatal hernia in 55 patients (81%), while endoscopy demonstrated 16 cases of histologically severe esophagitis (23.5%) and 52 of mild esophagitis (76.5%). No intraoperative/postoperative complications were recorded. 60patients had a complete follow-up (range 1-20 years). 60/68 patients were evaluated with barium-swallow-study at 6-12 months; 40/68 patients with upper-gastrointestinal-endoscopy at 12months. No relapse was reported. 50 patients (73.7%) were symptom-free. 18 (26.3%) referred occasional epigastric pain, associated with vomit in 2 cases. 64 (94.1%) referred ability to vomit; 4 temporary difficulty to swallow (average 30 days). All patients reported being able to burp. 3(4.5%) presented episodes of gas-air-bloat during the first 2 months with spontaneous resolution. No case of dumping syndrome was recorded. This technique's modification yields excellent results in term of relapse and side effects at long-term follow-up. We reported the first and largest pediatric series in non-neurological children with encouraging results.

Mycophenolate Mofetil Dose Adjustment in Pediatric Kidney Transplant Recipients.

The Immunosuppressant Bayesian Dose Adjustment web site aids clinicians and pharmacologists involved in the care of transplant recipients; it proposes dose adjustments based on the estimated area under the concentration-time curve (AUCs). Three concentrations (T 20 min , T 1 h , and T 3 h ) are sufficient to estimate mycophenolic acid (MPA) AUC 0-12 h in pediatric kidney transplant recipients. This study investigates mycophenolate mofetil (MMF) doses and MPA AUC values in pediatric kidney transplant recipients, and target exposure attainment when the proposed doses were followed, through a large-scale analysis of the data set collated since the inception of the Immunosuppressant Bayesian Dose Adjustment web site. In this study, 4051 MMF dose adjustment requests, corresponding to 1051 patients aged 0-18 years, were retrospectively analyzed. AUC calculations were performed in the back office of the Immunosuppressant Bayesian Dose Adjustment using published Bayesian and population pharmacokinetic models. The first AUC request was posted >12 months posttransplantation for 41% of patients. Overall, only 50% had the first MPA AUC 0-12 h within the recommended 30-60 mg.h/L range. When the proposed dose was not followed, the proportion of patients with an AUC in the therapeutic range for MMF with cyclosporine or tacrolimus at the subsequent request was lower (40% and 45%, respectively) than when it was followed (58% and 60%, respectively): P = 0.08 and 0.006, respectively. Furthermore, 3 months posttransplantation, the dispersion of AUC values was often lower at the second visit when the proposed doses were followed, namely, P = 0.03, 0.003, and 0.07 in the 4 months-1 year, and beyond 1 year with <6-month or >6-month periods between both visits, respectively. Owing to extreme interindividual variability in MPA exposure, MMF dose adjustment is necessary; it is efficient at reducing such variability when based on MPA AUC.

Racial and ethnic disparities in insufficient sleep among US in infants and preschoolers

ObjectiveTo examine racial and ethnic disparities and associated factors of insufficient sleep among children from infancy to preschool-aged. MethodsWe analyzed parent-reported data on US children ages 4 months-5 years (n = 13,975) from the 2018 and 2019 National Survey of Children's Health. Children who slept less than the age-specific minimum hours recommended by the American Academy of Sleep Medicine were classified as having insufficient sleep. Logistic regression was used to estimate unadjusted and adjusted odds ratios (AOR). ResultsAn estimated 34.3% of children from infancy to preschool-aged experienced insufficient sleep. Socioeconomic factors (poverty [AOR] = 1.5, parents’ education level [AORs] from 1.3 to 1.5); parent-child interaction variables (AORs from 1.4 to 1.6); breast feeding status (AOR = 1.5); family structure (AORs from 1.5 to 4.4); and weeknight bedtime regularity (AORs from 1.3 to 3.0) were significantly associated with having insufficient sleep. Non-Hispanic Black (OR = 3.2) and Hispanic children (OR = 1.6) had significantly higher odds of insufficient sleep compared to non-Hispanic White children. Racial and ethnic disparities in insufficient sleep between non-Hispanic White children and Hispanic children were largely attenuated by adjusting for social economic factors. However, the difference in insufficient sleep between non-Hispanic Black and non-Hispanic White children remains (AOR = 1.6) after adjusting socioeconomic and other factors. ConclusionsMore than one-third of the sample reported insufficient sleep. After adjusting for socio-demographic variables, racial disparities in insufficient sleep decreased but persistent disparities existed. Further research is warranted to examine other factors and develop interventions to address multilevel factors and improve sleep health among racial and ethnic minority group children.

COVID-19 Vaccination Coverage and Demographic Characteristics of Infants and Children Aged 6 Months–4 Years — United States, June 20–December 31, 2022

Although severe COVID-19 illness and hospitalization are more common among older adults, children can also be affected (1). More than 3 million cases of COVID-19 had been reported among infants and children aged <5 years (children) as of December 2, 2022 (2). One in four children hospitalized with COVID-19 required intensive care; 21.2% of cases of COVID-19-related multisystem inflammatory syndrome in children (MIS-C) occurred among children aged 1-4 years, and 3.2% of MIS-C cases occurred among infants aged <1 year (1,3). On June 17, 2022, the Food and Drug Administration issued an Emergency Use Authorization (EUA) of the Moderna COVID-19 vaccine for children aged 6 months-5 years and the Pfizer-BioNTech COVID-19 vaccine for children aged 6 months-4 years. To assess COVID-19 vaccination coverage among children aged 6 months-4 years in the United States, coverage with ≥1 dose* and completion of the 2-dose or 3-dose primary vaccination series† were assessed using vaccine administration data for the 50 U.S. states and District of Columbia submitted from June 20 (after COVID-19 vaccine was first authorized for this age group) through December 31, 2022. As of December 31, 2022, ≥1-dose COVID-19 vaccination coverage among children aged 6 months-4 years was 10.1% and was 5.1% for series completion. Coverage with ≥1 dose varied by jurisdiction (range=2.1% [Mississippi] to 36.1% [District of Columbia]) as did coverage with a completed series (range=0.7% [Mississippi] to 21.4% [District of Columbia]), respectively. By age group, 9.7 % of children aged 6-23 months and 10.2% of children aged 2-4 years received ≥1 dose; 4.5% of children aged 6-23 months and 5.4% of children aged 2-4 years completed the vaccination series. Among children aged 6 months-4 years, ≥1-dose COVID-19 vaccination coverage was lower in rural counties (3.4%) than in urban counties (10.5%). Among children aged 6 months-4 years who received at least the first dose, only 7.0% were non-Hispanic Black or African American (Black), and 19.9% were Hispanic or Latino (Hispanic), although these demographic groups constitute 13.9% and 25.9% of the population, respectively (4). COVID-19 vaccination coverage among children aged 6 months-4 years is substantially lower than that among older children (5). Efforts are needed to improve vaccination coverage among children aged 6 months-4 years to reduce COVID-19-associated morbidity and mortality.

Preliminary Estimates of Effectiveness of Monovalent mRNA Vaccines in Preventing Symptomatic SARS-CoV-2 Infection Among Children Aged 3-5 Years - Increasing Community Access to Testing Program, United States, July 2022-February 2023.

On June 18, 2022, the Advisory Committee on Immunization Practices (ACIP) issued interim recommendations for use of the 2-dose monovalent Moderna COVID-19 vaccine as a primary series for children aged 6 months-5 years* and the 3-dose monovalent Pfizer-BioNTech COVID-19 vaccine as a primary series for children aged 6 months-4 years,† based on safety, immunobridging, and limited efficacy data from clinical trials (1-3). Monovalent mRNA vaccine effectiveness (VE) against symptomatic SARS-CoV-2 infection was evaluated using the Increasing Community Access to Testing (ICATT) program, which provides SARS-CoV-2 testing to persons aged ≥3 years at pharmacy and community-based testing sites nationwide§ (4,5). Among children aged 3-5 years with one or more COVID-19-like illness symptoms¶ for whom a nucleic acid amplification test (NAAT) was performed during August 1, 2022-February 5, 2023, VE of 2 monovalent Moderna doses (complete primary series) against symptomatic infection was 60% (95% CI=49% to 68%) 2 weeks-2 months after receipt of the second dose and 36% (95% CI=15% to 52%) 3-4 months after receipt of the second dose. Among symptomatic children aged 3-4 years with NAATs performed during September 19, 2022-February 5, 2023, VE of 3 monovalent Pfizer-BioNTech doses (complete primary series) against symptomatic infection was 31% (95% CI=7% to 49%) 2 weeks-4 months after receipt of the third dose; statistical power was not sufficient to estimate VE stratified by time since receipt of the third dose. Complete monovalent Moderna and Pfizer-BioNTech primary series vaccination provides protection for children aged 3-5 and 3-4 years, respectively, against symptomatic infection for at least the first 4 months after vaccination. CDC expanded recommendations for use of updated bivalent vaccines to children aged ≥6 months on December 9, 2022 (6), which might provide increased protection against currently circulating SARS-CoV-2 variants (7,8). Children should stay up to date with recommended COVID-19 vaccines, including completing the primary series; those who are eligible should receive a bivalent vaccine dose.

Early-onset recurrent panniculitis as a phenotype of NLRC4-associated autoinflammatory syndrome: Characterization of pathogenicity of the p.Ser445Pro NLRC4 variant.

Monoallelic NLRC4 gain-of-function variants cause an inflammasomopathy with diverse clinical forms including infantile enterocolitis, recurrent macrophage activation syndrome, cold-induced urticaria-like lesions (or familial-cold autoinflammatory syndrome, FCAS4), and painful subcutaneous nodules. Here, we identified a large family with six consecutive generations affected. Genetic analyses detected the heterozygous p.Ser445Pro NLRC4 variant in three patients, which has been previously reported in a Dutch family with FCAS4. We aimed to describe the clinicopathological features and the functional consequences of the detected NLRC4 variant. Patients presented an early-onset (3months-6 years) inflammatory disease characterized by recurrent panniculitis, fever and arthralgia. Histopathological examination showed perivascular and interstitial lymphohistiocytic infiltrates in the dermis and mixed panniculitis. Functional analysis supported the conclusion that the p.Ser445Pro NLRC4 variant leads to a constitutive activation of NLRC4-inflammasome and increased plasma levels of IL-18. Prompt recognition of early-onset panniculitis through clinicopathological examination and laboratory biomarkers may allow targeted therapies.

Spongioplasty with Buck's fascia covering dorsal inlay graft urethroplasty for primary hypospadias repair

Neourethral covering is an essential technique for preventing complications such as fistula and glans dehiscence in hypospadias repairs. The spongioplasty has been reported for neourethral coverage about 20 years ago. However, reports of the outcome are limited. This study aimed to retrospectively evaluate the short-term outcome of spongioplasty with Buck's fascia covering dorsal inlay graft urethroplasty (DIGU). From December 2019 to December 2020, 50 patients with primary hypospadias (median age at surgery, 37 months; range, 10 months-12 years) were treated by a single pediatric urologist. The patients underwent spongioplasty with Buck's fascia covering dorsal inlay graft urethroplasty in single stage. The penile length, glans width, urethral plate width and length, and the location of the meatus of the patients were recorded preoperatively. The patients were followed up,complications noted, and postoperative uroflowmetries at the one-year follow-up time were evaluated. The average width of glans was 12.92±1.86mm. A minor penile curvature was observed in all patients (≤30°). The patients were followed up for 12-24 months, and 47 patients (94%) were free from complications. A neourethra formed with a slit-like meatus at the tip of the glans, and the urinary stream was straight. Three patients had coronal fistulae (3/50) and no glans dehiscence, and the mean±SD Qmax of postoperative uroflowmetry was 8.13±3.8ml/s. This study estimated the short-term outcome of the DIGU covered using spongioplasty with Buck's fascia as the second layer in patients diagnosed with primary hypospadias with a relatively small glans (average width <14mm). However, only a few reports emphasize spongioplasty with Buck's fascia as the second layer and the DIGU procedure performed on a relatively small glans. The major limitations of this study were its short follow-up time and the retrospective data collection. Dorsal inlay graft urethroplasty combined with spongioplasty with Buck's fascia as coverage is an effective procedure. In our study, this combination had good short-term outcomes for primary hypospadias repair.

Cross-cultural adaptation and validation of the Italian version of the Montreal Children's Hospital Feeding Scale in a special healthcare needs population.

The Montreal Children's Hospital Feeding Scale (MCH-FS) allows paediatricians and other health care professionals to identify feeding difficulties among children. To translate and adapt the MCH-FS into Italian, and to evaluate the validity and reliability of this Italian version of the Montreal Children's Hospital Feeding Scale (I-MCH-FS). A total of 150 children with special healthcare needs were admitted to the Rare Disease Unit of the Paediatrics Department at the Fondazione Policlinico Universitario Agostino Gemelli IRCCS, Rome, Italy, between March 2021 and March 2022 (74 males; mean age = 3.85 ± 1.96 years; median age = 4 years; age range = 6 months-6 years and 11 months) and 150 healthy participants (83 males; mean age = 3.5 ± 1.98 years; median age = 3 years; age range = 6 months-6 years and 11 months) were included in the study, which was approved by the local ethics committee. The original version of the MCH-FS was translated and cross-cultural adapted through five stages: (1) initial translation, (2) synthesis of the translations, (3) back translation, (4) expert committee and (5) test of the prefinal version. Test-retest reliability and internal consistency were assessed using Pearson r, Spearman r and Cronbach's alpha, respectively. Construct validity was established by comparing data obtained from patients with those of healthy participants using the Mann-Whitney U-test. A Pearson r of 0.98, a Spearman r of 0.95 and Cronbach's alpha value of 0.86 were obtained. In the clinical group, 40.6% children were classified as having feeding disorders (n = 61), while in the normative group 4.7% were diagnosed with feeding problems (n = 7). Mean total score of the clinical group was significatively different from the normative's. The I-MCH-FS is a valid and reliable one-page, quick screening tool used to identify feeding disorders among children with special needs in outpatient paediatric setting. What is already known on the subject The MCH-FS is a valid and reliable parent-report measure aimed at discriminating between children presenting or not feeding disorders. What this paper adds to existing knowledge This paper presents the translation and cross-cultural adaptation of the scale into the Italian language. What are the potential or actual clinical implications of this work? The Italian version of the MCH-FS can be used in the special healthcare needs population.

Executive function and behaviour problems in school-age children born at risk of neonatal hypoglycaemia.

To examine the relationship between neonatal hypoglycaemia and specific areas of executive function and behaviour in mid-childhood. Participants in a prospective cohort study of infants born late preterm or at term at risk of neonatal hypoglycaemia were assessed at 9 to 10 years. We assessed executive function using performance-based (Cambridge Neuropsychological Tests Automated Battery) and questionnaire-based (Behavior Rating Inventory of Executive Function) measures and behaviour problems with the Strengths and Difficulties Questionnaire. Data are reported as adjusted odds ratio (aOR) with 95% confidence intervals, and standardized regression coefficients. We assessed 480 (230 females, 250 males; mean age 9 years 5 months [SD 4 months, range 8 years 8 months-11 years 0 months]) of 587 eligible children (82%). There were no differences in performance-based executive function between children who did and did not experience neonatal hypoglycaemia (blood glucose <2.6 mmoL/L). However, children who experienced hypoglycaemia, especially if severe or recurrent, were at greater risk of parent-reported metacognition difficulties (aOR 2.37-3.71), parent-reported peer (aOR 1.62-1.89) and teacher-reported conduct (aOR 2.14 for severe hypoglycaemia) problems. Both performance- and questionnaire-based executive functions were associated with behaviour problems. Neonatal hypoglycaemia may be associated with difficulties in specific aspects of parent-reported executive functions and behaviour problems in mid-childhood.

Perbedaan Manifestasi Klinis Kejang Demam Pada Anak Anemia dengan Tanpa Anemia di RSPAL dr. Ramelan Surabaya Tahun 2019-2022

Study aims: Febrile seizures are the most common neurological disorder in children. The incidence of febrile seizures is related to the incidence of epilepsy at 2-4% in the future and the probability of recurrence is about 30% and 50% after the first and second febrile seizures, respectively. Several recent studies have suggested that febrile seizures are more common in children with anemia. Anemia patients who experience febrile seizures can cause more severe clinical manifestations. Where 40.5% of the incidence of anemia in Indonesia occurs in children under the age of 5 years. Therefore, this study is conducted to determine the differences of the clinical manifestations of febrile seizures with and without anemia in children at RSPAL Dr. Ramelan Surabaya on 2019-2022.&#x0D; Methods: This study was an observational analytic study with a cross-sectional study approach and qualitative methods from secondary medical record data of infants and children aged 6 months-5 years at RSPAL Dr. Ramelan Surabaya for the period May 2019-May 2022. The number of samples in this study was 82 samples.&#x0D; Results: The characteristics of the sample which experiences the most febrile seizures occurres between the ages of 6-18 months, the gender of male with a temperature &gt;38°C and manifestations in the form of simple febrile seizures. In addition, the results of the fisher exact test with a significance level of 5% shows p = 0.96 which means there is no difference in the clinical manifestations of febrile seizures in anemic and non-anemic children.&#x0D; Conclusion: The conclusion of this study is that based on the classification of febrile seizures, the most common clinical manifestations that occur in children with anemia and without anemia are simple febrile seizures. So that there is no difference in the clinical manifestations of febrile seizures in anemic children and without anemia.

Prediction of Wilms' Tumor Susceptibility to Preoperative Chemotherapy Using a Novel Computer-Aided Prediction System.

Wilms' tumor, the most prevalent renal tumor in children, is known for its aggressive prognosis and recurrence. Treatment of Wilms' tumor is multimodal, including surgery, chemotherapy, and occasionally, radiation therapy. Preoperative chemotherapy is used routinely in European studies and in select indications in North American trials. The objective of this study was to build a novel computer-aided prediction system for preoperative chemotherapy response in Wilms' tumors. A total of 63 patients (age range: 6 months-14 years) were included in this study, after receiving their guardians' informed consent. We incorporated contrast-enhanced computed tomography imaging to extract the texture, shape, and functionality-based features from Wilms' tumors before chemotherapy. The proposed system consists of six steps: (i) delineate the tumors' images across the three contrast phases; (ii) characterize the texture of the tumors using first- and second-order textural features; (iii) extract the shape features by applying a parametric spherical harmonics model, sphericity, and elongation; (iv) capture the intensity changes across the contrast phases to describe the tumors' functionality; (v) apply features fusion based on the extracted features; and (vi) determine the final prediction as responsive or non-responsive via a tuned support vector machine classifier. The system achieved an overall accuracy of 95.24%, with 95.65% sensitivity and 94.12% specificity. Using the support vector machine along with the integrated features led to superior results compared with other classification models. This study integrates novel imaging markers with a machine learning classification model to make early predictions about how a Wilms' tumor will respond to preoperative chemotherapy. This can lead to personalized management plans for Wilms' tumors.

Percutaneous Full Endoscopic Management of Spinal Foraminal Schwannomas: Case Series.

Schwannoma, a benign peripheral nerve sheath tumor, is perhaps only secondary to degenerative pathology as the most common lesion at neural foramen. The surgical dilemma here is either risking nerve injury because of inadequate exposure or the need for internal fixation because of facet joint sacrifice. To evaluate the feasibility and safety of management of foraminal schwannomas by percutaneous full-endoscopic technique. A single-center retrospective review was conducted on patients who underwent full-endoscopic resection of neural foraminal schwannomas. Tumors were grouped into either medial type or lateral type based on relevant location to the neural foramen, and respective surgical approaches were adopted. Data including preoperative neurological status, tumor size, surgery time, the extension of resection, and clinical outcomes were collected. The learning curve was plotted as surgical time/tumor size against case number. A total of 25 patients were treated between May 2015 and March 2022. Gross total resection was achieved in 24 patients, and near-total resection in 1 case, with 1 patient experienced transient voiding difficulty. No tumor recurrence or spinal instability was detected in the short-term follow-up (median follow-up 22 months, range 3 months-6 years). Surgical efficiency improved with the number of cases operated on and remained stable after the initial 10 cases. Percutaneous full-endoscopic technique is a safe and minimally invasive technique for the resection of foraminal schwannomas.

Anatomical and functional results of surgical treatment of familial exudative vitreoretinopathy in children

Familial exudative vitreoretinopathy (FEVR) is a rare hereditary disease characterized by abnormal angiogenesis, presence of avascular zones on the periphery of the retina, and clinical manifestations ranging from an asymptomatic course to total retinal detachment. Surgical interventions are performed to eliminate vitreoretinal traction, epiretinal membranes, and retinal detachment. Studies of the surgical treatment outcomes of patients with FEVR are limited and findings are ambiguous&#x0D; AIM: To analyze surgical treatment outcomes of different stages of FEVR in childhood.&#x0D; MATERIAL AND METHODS: From January 2012 to October 2021 at the Helmholtz National Medical Research Center of Eye Diseases, surgical treatment was performed in 35 eyes of 33 patients aged 11 months15 years (average, 7 years). The effectiveness of treatment was evaluated 12 months after the treatment, and patients were examined every 36 months for 15 years (average 2 years).&#x0D; RESULTS: Аfter the primary surgery, a decrease in retinal traction in the posterior pole and periphery was achieved in all cases. Complete and incomplete reattachment was achieved in 30% and 70% of the eyes at stage 3 and in 12.5% and 87.5% of the eyes at stage 4, respectively. The long-term effectiveness rates of the intervention in stages 2, 3 (including complete and incomplete reattachment), and 4 were 100%, 87.5%, and 73.3%, respectively.&#x0D; Increases in the best-corrected visual acuity (BCVA) were observed in 83%, 50%, and 28.6% of the eyes in stages 2, 3, and 4, respectively. In other cases, successful surgical treatment allowed the preservation of visual functions. During the follow-up, visual acuity of 0.1 or more was maintained in 100%, 85.7%, and 36% of the eyes at stages 2, 3, and 4 of FEVR, respectively.&#x0D; CONCLUSION: Аnatomical and functional results of surgical treatment of FEVR correlate with the disease stage: the efficiency is greater in stage 2, and it was organ-preserving surgery in stage 5. To increase the effectiveness of treatment, early diagnosis of FEVR, laser coagulation of avascular zones, and active vessels are necessary, which makes it possible to stop the progression of the early stages of FEVR in 70%100% of cases and enables regular monitoring of patients for the timely detection of indications for additional laser coagulation or surgical intervention.

Efficacy of pyriproxyfen-pyrethroid long-lasting insecticidal nets (LLINs) and chlorfenapyr-pyrethroid LLINs compared with pyrethroid-only LLINs for malaria control in Benin: a cluster-randomised, superiority trial

New classes of long-lasting insecticidal nets (LLINs) combining mixtures of insecticides with different modes of action could put malaria control back on track after rebounds in transmission across sub-Saharan Africa. We evaluated the relative efficacy of pyriproxyfen-pyrethroid LLINs and chlorfenapyr-pyrethroid LLINs compared with standard LLINs against malaria transmission in an area of high pyrethroid resistance in Benin. We conducted a cluster-randomised, superiority trial in Zou Department, Benin. Clusters were villages or groups of villages with a minimum of 100 houses. We used restricted randomisation to randomly assign 60 clusters to one of three LLIN groups (1:1:1): to receive nets containing either pyriproxyfen and alpha-cypermethrin (pyrethroid), chlorfenapyr and alpha-cypermethrin, or alpha-cypermethrin only (reference). Households received one LLIN for every two people. The field team, laboratory staff, analyses team, and community members were masked to the group allocation. The primary outcome was malaria case incidence measured over 2 years after net distribution in a cohort of children aged 6 months-10 years, in the intention-to-treat population. This study is ongoing and is registered with ClinicalTrials.gov, NCT03931473. Between May 23 and June 24, 2019, 53 854 households and 216 289 inhabitants were accounted for in the initial census and included in the study. Between March 19 and 22, 2020, 115 323 LLINs were distributed to 54 030 households in an updated census. A cross-sectional survey showed that study LLIN usage was highest at 9 months after distribution (5532 [76·8%] of 7206 participants), but decreased by 24 months (4032 [60·6%] of 6654). Mean malaria incidence over 2 years after LLIN distribution was 1·03 cases per child-year (95% CI 0·96-1·09) in the pyrethroid-only LLIN reference group, 0·84 cases per child-year (0·78-0·90) in the pyriproxyfen-pyrethroid LLIN group (hazard ratio [HR] 0·86, 95% CI 0·65-1·14; p=0·28), and 0·56 cases per child-year (0·51-0·61) in the chlorfenapyr-pyrethroid LLIN group (HR 0·54, 95% CI 0·42-0·70; p<0·0001). Over 2 years, chlorfenapyr-pyrethroid LLINs provided greater protection from malaria than pyrethroid-only LLINs in an area with pyrethroid-resistant mosquitoes. Pyriproxyfen-pyrethroid LLINs conferred protection similar to pyrethroid-only LLINs. These findings provide crucial second-trial evidence to enable WHO to make policy recommendations on these new LLIN classes. This study confirms the importance of chlorfenapyr as an LLIN treatment to control malaria in areas with pyrethroid-resistant vectors. However, an arsenal of new active ingredients is required for successful long-term resistance management, and additional innovations, including pyriproxyfen, need to be further investigated for effective vector control strategies.

Unilateral Vocal Fold Paralysis and Voice Therapy: Predictors of Long-Term Quality of Life.

To date, little is known about the long-term predictors of quality of life (QoL) in unilateral vocal fold paralysis (UVFP). The main objective of this study was to evaluate the predictors of long-term QoL in UVFP patients submitted to voice therapy (VT) exclusively. Data from patients diagnosed with UVFP who followed a VT program between 2013 and 2019 were reviewed. Video laryngoscopy (VL) records were obtained at the beginning and at the end of VT. To assess QoL, Voice Handicap Index 30 (VHI-30) score was assessed in three temporal frames: before voice therapy (pre-VT), at the last VT session (post-VT), and in the present (cur-VHI). A longitudinal analysis was performed regarding the evolution of QoL and the factors influencing QoL through time were analyzed. Seventy-eight percent of patients had iatrogenic UVFP. The mean time of follow-up after VT was 3.942 years (range 6 months-7 years). There was a significant improvement in QoL through all time points (F (2,88)=72.179, p<0.001), with VHI-30 decrease from the baseline pre-VT to post-VT(p<0.001) and from post-VT to cur-VT (p=0.0013). In the iatrogenic UVFP population, patients starting VT earlier showed better long-term QoL (p=0.023). UVFP patients with dysphagia at presentation showed significantly worse QoL in the late follow-up (p=0.016). Hence, iatrogenic UVFP patients beginning VT rapidly may show better QoL in the future. Also, our results suggest that dysphagia at UVFP onset may predict higher morbidity later in life.

Evaluation of some biochemical parameters of pediatric patients hospitalized for rotavirus in Şirnak Province: A retrospective review

Rotavirus gastroenteritis is an important cause of worldwide morbidity and mortality in infants and children. The main cause of mortality is dehydration due to fluid loss and malnutrition. This study aims to examine the guiding parameters of uric acid and creatinine levels in the detection of dehydration and fluid deficit and inpatient management in cases of rotavirus gastroenteritis. Children who applied to Şirnak State Hospital, Pediatrics Polyclinics, children (6 months-18 years old) whose faecal samples were sent to the laboratory by the research pediatrician considering the diagnosis of rotavirus and whose microbiological examinations were confirmed by immunochromatographic methods (6 months-18 years old), were included in the study by scanning the system. When positive patients were evaluated, the mean age for serum uric acid was 1.06±1.53 and the mean age for serum creatinine was 1.10±1.37. The median value was 3.75 mg/dL in negative patients with serum uric acid levels, and 5.25 mg/dL in positive patients, which was statistically significant (p&lt;0.01). The median value of serum creatinine level was 0.41 mg/dL in negative patients and 0.43 mg/dL in positive patients, which was statistically significant (p&lt;0.05). With this study carried out in Şirnak province, we think that children in the region are severely affected by the rotavirus and face severe dehydration. Therefore, we think that all parameters affected by rotavirus should be evaluated according to regions and parents should be educated about the importance of rotavirus vaccine in the prevention of rotavirus gastroenteritis.

Patterns and management outcome of paediatrics burn in a general surgical department: experience from a secondary referral hospital.

Burns are considered the fourth most common type of traumatic injury worldwide with significant morbidity and mortality. The aim of this study is to disclose the incidence, etiological factors, treatment and outcome of paediatric burns in Sudan. This is a retrospective hospital-based study, conducted during 2016-2019. Patients who presented with burn injuries and managed in the hospital were included in the study. Flowchart sheets were used to collect the data. Then, it was entered and analysed using Statistical Package for the Social Sciences version 21 statistical software (IBM Corporation, Chicago, IL). The total number of patients who fulfill our criteria is 85 with a median age of 4 years (7 months-15 years). Sixty-five percent of them were under 5 years with male predominance (55%). Most patients' burns occurred at home. The median percentage of burn is 18% (2%-90%) which is caused by scalding burn among 55.3% followed by the flame burn in 41.2% of patients. Regarding fluid management, 60% received fluid. Open dressing for burn wounds was done for 75% and close dressing among 15% of patients. More than 80% of the patients in this study were treated and discharged in a good condition while the mortality was 5.9%. This study showed the significant burden of paediatric burns management on general surgery units in a referral hospital. Therefore, equipping the hospital and founding these specialities will decrease this load and will improve the outcome.

Voiding Pressures in Boys: Pdetmax versus PdetQmax - Does it Make a Difference?

Invasive urodynamics (UDS) is a standard investigation in children. Studies measuring voiding pressures in children use varied nomenclatures and quote a wide range of voiding pressures. Thus, voiding pressures in children are not considered reliable and they do not find any place in the pediatric diagnostic armamentarium. On the contrary, adult studies have well-defined nomograms and standard values which make voiding studies indispensable in the diagnosis of voiding dysfunctions in adults. The difference primarily lies in the uniformity of parameters assessed in adults and the contrasting heterogeneity in the pediatric literature. The objective of this study was to study the voiding parameters observed during UDS in boys. We retrospectively reviewed the pressure flow data obtained during conventional invasive UDS in 106 neurologically normal boys (6 months-16 years) who had different indications for urodynamics. The values of Pdetmax and PdetQmax were analyzed and compared with the existing data of pressure flow studies in children. Pdetmax decreased with age whereas PdetQmax was independent of age. The difference between the values of Pdetmax and PdetQmax was more in the younger kids. The wide range of voiding detrusor pressure (Pdet) in the existing pediatric literature is similar to the values of Pdetmax observed in our study, whereas the value of PdetQmax is much lower. The values of Pdetmax observed in this study are similar to the values of "maximum Pdet during voiding" documented in previous studies and are determined by detrusor contractility and functional/dynamic contraction of outflow during voiding. PdetQmax has been documented in very few pediatric studies and is significantly less than Pdetmax. Further prospective studies are needed to corroborate UDS findings with radiologic/cystoscopic findings to create nomograms of voiding parameters in children. Existing literature on pediatric voiding studies mentions voiding pressures during variable phases of void (usually Pdetmax) and the values have been very heterogeneous, making voiding pressure-flow studies unreliable in children. PdetQmax values are much lower than values quoted as "standard" pressures and are age independent. The use of PdetQmax instead of PdetMax may make voiding pressures in children more reproducible and informative.
