The role of IGF1 in determining body composition in children and adolescents with growth hormone deficiency and those with idiopathic short stature.

PURPOSE: Treatment with recombinant human growth hormone (rhGH) increases insulin growth factor-1 (IGF1) levels, therefore, monitoring both IGF1 and growth constitutes an acceptable parameter of therapeutic safety and efficacy. We aimed to investigate the relationship between IGF1 level and body composition in children and adolescents undergoing rhGH therapy for growth hormone deficiency (GHD) and idiopathic short stature (ISS). METHODS: This observational retrospective study included the bioimpedance analysis (BIA) reports (n = 305) of 135 pediatric patients (age 5-18 years), 64 with GHD and 71 with ISS, conducted as part of routine clinic visits. Sociodemographic and clinical data were extracted from medical records. Generalized estimating equations linear models were used to explore the contributing factors for body composition components of fat percentage (FATP), appendicular skeletal muscle mass (ASMM) z-score, and muscle-to-fat ratio (MFR) z-score while adjusting for cumulative doses of rhGH. RESULTS: Subjects with GHD exhibited higher body mass index z-scores (p < 0.001), higher FATP and truncal FATP scores, lower MFR z-score, and higher diastolic blood pressure percentiles than the ISS group (p = 0.010, p = 0.027, p = 0.050, and p = 0.050, respectively). Female sex (p < 0.001) and a GHD diagnosis (p < 0.001), were major contributors to higher FATP scores; female sex (p = 0.049) and ISS diagnosis (p = 0.005) were major contributors to higher MFR z-scores; and female sex (p < 0.001), older age (p < 0.001) and higher insulin-like growth factor 1 z-scores (p = 0.021) were major contributors to higher ASMM z-scores. Socioeconomic position and cumulative rhGH dose were not significant contributors to body composition parameters. CONCLUSION: Children with GHD, including those undergoing rhGH treatment, may be at risk for increased adiposity and associated metabolic implications. Sex- and age-adjusted IGF1 levels were related to muscle mass but not to adiposity. Hence, rhGH treatment aimed at increasing IGF1 levels may alleviate these effects by promoting muscle growth.

Effectiveness of the Antiparasitic Combination of Albendazole and Praziquantel As Compared With Albendazole Monotherapy in the Treatment of Neurocysticercosis in Children: A Systematic Review and Meta-Analysis.

Neurocysticercosis, caused by the tapeworm Taenia solium, is a neglected tropical illness that affects millions of people worldwide. The disease leads to seizures and epilepsy as the larvae invade the nervous system. Treatment with albendazole and praziquantel is common, but the comparative effectiveness of combination therapy versus monotherapy is unclear. This study evaluated the effectiveness of albendazole and praziquantel combination therapy versus albendazole monotherapy for lesion resolution in pediatric neurocysticercosis. The study aimed to assess the effectiveness of the antiparasitic combination of albendazole and praziquantel as compared with albendazole monotherapy in the treatment of neurocysticercosis in children. This study is based on a systematic review and meta-analysis following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria. Randomized controlled trials on pediatric patients receiving the mentioned therapies were included. The risk-of-bias tool for randomized trials assessed the study quality once data extraction and analysis were completed. This study included randomized research in neurocysticercosis pediatric patients diagnosed with neuroimaging outcomes, using albendazole and praziquantel combination therapy or albendazole monotherapy. We searched articles between September 30 and December 1, 2023. All terms followed the Medical Subject Headings (MeSH) browser, and 13 articles were found. The data was quantitatively analyzed using RevMan 5.4.1 (The Nordic Cochrane Center, The Cochrane Collaboration, Copenhagen, Denmark). We applied the relative risk (RR) for the intervention and control groups before and after treatment, obtained from prior studies on lesion result resolution. The statistical method was Mantel-Haenszel. The model analysis we used was a fixed effect model (FEM) for heterogeneity (I2) < 50% and a random effect model (REM) for I2 ≥ 50%. The impact was measured using the risk difference (RD) by study and the overall 95% confidence interval (CI). The meta-analysis indicated that combination therapy was more effective in achieving complete lesion resolution after both three months (pooled RD = 0.18, 95% CI = 0.03-0.33, p= 0.02, I2 =0%) and six months (pooled RD = 0.24, 95% CI = 0.09-0.40, p = 0.002, I2 =0%) of therapy. However, calcification outcomes were also more significant in the combination therapy group. The study demonstrates that the albendazole and praziquantel combination therapy is superior in lesion resolution in pediatric neurocysticercosis. Clinical caution is advised to prevent calcification during treatment.

Limbal graft transplantation: a rare implementation in pediatric limbal stem cell deficiency.

PURPOSE: To evaluate limbal graft transplantation success in pediatric patients with chemical injury-induced limbal stem cell deficiency (LSCD) using the 'LSCD Working Group' staging system. METHODS: Medical records of 11 eyes of 11 children who underwent limbal graft transplantation (limbal autograft/limbal allograft) were included. Surgical success was defined as improvement in the post-operative 1st year LSCD stage. RESULTS: The mean age was 12 ± 5 (4-17) years. Causative agent was alkaline in 4(36.4%) and acid in 3(27.2%) patients. Limbal autograft was performed in 9 (81.8%) eyes with unilateral LSCD, and allograft transplantation was performed in 2 (18.2%) eyes with bilateral LSCD. The mean follow-up time was 33.89 ± 30.73 (12-102.33) months. The overall limbal graft transplantation success rate was 72.7%. Among 9 patients who receive limbal autograft, 8 had improvement in post-operative LSCD stage, 1 had stable LSCD stage. Of the 2 patients who receive limbal allograft, post-operative LSCD stage remained the same in 1 and worsened in 1 patient. The mean time between injury and the surgery was 30.47 ± 30.08 (7-108.47) months. Penetrating keratoplasty was performed in 3 (27.2%) of 11 patients following limbal graft transplantation. CONCLUSION: Management of LSCD in children is challenging and appears to be somewhat different from that of adults. Limited data in the literature indicate that cultivated or simple limbal epithelial transplantations (CLET/SLET) are primarily preferred in children. Although the tendency to take small tissue from the healthy eye is noteworthy, conventional limbal allograft and autograft transplantations also show promising results without any further complications in at least 1 year follow-up period.

An update on tinea capitis in children.

Tinea capitis presents a significant public health care challenge due to its contagious nature, and potential long-term consequences if unrecognized and untreated. This review explores the prevalence, risk factors, diagnostic methods, prevention strategies, impact on quality of life, and treatment options for pediatric tinea capitis. Epidemiological analysis spanning from 1990 to 1993 and 2020 to 2023 reveals prevalence patterns of pediatric tinea capitis influenced by geographic, demographic, and environmental factors. Notably, Trichophyton species is most prevalent in North America; however, Microsporum species remain the primary causative agent globally, with regional variations. Risk factors include close contact and environmental conditions, emphasizing the importance of preventive measures. Accurate diagnosis relies on clinical evaluation, microscopic examination, and fungal culture. Various treatment modalities including systemic antifungals show efficacy, with terbinafine demonstrating superior mycological cure rates particularly for Trichophyton species. Recurrent infections and the potential development of resistance can pose challenges. Therefore, confirming the diagnosis, appropriately educating the patient/caregiver, accurate drug and dose utilization, and compliance are important components of clinical cure. Untreated or poorly treated tinea capitis can lead to chronic infection, social stigma, and psychological distress in affected children. Prevention strategies focus on early detection and healthy lifestyle habits. Collaborative efforts between healthcare providers and public health agencies are important in treating pediatric tinea capitis and improving patient outcomes. Education and awareness initiatives play a vital role in prevention and community-level intervention to minimize spread of infection. Future research should explore diagnostic advances, novel treatments, and resistance mechanisms in order to mitigate the disease burden effectively.

Clinical Features and Visual Outcome of Infectious Keratitis Associated with Orthokeratology Lens in Korean Pediatric Patients.

Purpose: To investigate the clinical features and visual outcome of infectious keratitis associated with Orthokeratology (Ortho-K) lens in Korean pediatric patients. Methods: We retrospectively reviewed medical records of patients diagnosed with Ortho-K lens-associated infectious keratitis from June 2005 to April 2020 at a tertiary referral hospital. Patients' demographics, clinical features, microbiological evaluation, and treatment methods were assessed and factors related to final visual outcomes were analyzed. Results: The study included 26 eyes of 26 patients (19 female, 7 male; mean age: 11.9 years), with an average Ortho-K lens wear duration of 33.7 ± 21.2 months. The highest number of cases occurred in summer (42.3%, 11/26). Central or paracentral corneal lesions were observed in 96.2% (25/26) of cases, with a mean corneal epithelial defect size of 5.13 mm². Pseudomonas aeruginosa was the most commonly isolated organism (n = 5), followed by Serratia marcescens (n = 4). All patients responded to medical treatment without needing surgical intervention. 72% of cases achieved favorable visual outcomes (Snellen BCVA > 6/12), while 8% experienced severe visual impairment (Snellen BCVA ≤ 6/60) due to residual central corneal opacities. Multivariable analysis showed that non-summer seasons, duration from symptom onset to presentation, and corneal epithelial defect size were significantly associated with final logMAR BCVA (p = 0.043, p = 0.040, and p = 0.002, respectively). Failed autorefraction at presentation due to an Ortho-K-related infectious keratitis lesion was a significant predictor of poor final visual outcome (Snellen BCVA ≤ 6/12) (OR = 38.995, p = 0.030). Conclusions: Ortho-K lens-related infectious keratitis can lead to permanent corneal opacities and potentially devastating visual outcomes in children. Delayed time to presentation, large corneal lesions, failure of autorefraction, and non-summer seasons were associated with poorer outcomes. Proper education and early detection would be key to safe use of orthokeratology lenses in pediatric patients.

Analysis of perioperative autonomic nervous system activity to visualize stress in pediatric patients undergoing alveolar bone graft surgery.

Perioperative stress in pediatric patients is often difficult to assess via interviews; thus, an objective measure to assess perioperative stress is needed. To visualize perioperative stress, we observed autonomic nervous system (ANS) activity, circulatory dynamics, and psychological status in pediatric patients undergoing alveolar bone grafting under general anesthesia. This prospective observational study included 40 patients aged 8-12 years who were scheduled for alveolar bone grafting in our hospital. ANS activity was analyzed using heart rate variability the day before surgery, during general anesthesia, 2 h postoperatively, 24 h postoperatively, and the day before discharge. ANS assessment included LF/HF (sympathetic nervous system activity) and HF (parasympathetic nervous system activity). Additionally, heart rate (HR), systolic blood pressure (SBP), face scale (FS) score were recorded. Data from 31 patients, excluding dropouts, were analyzed. The ratio of change to the preoperative value was compared. After surgery, the LF/HF, HR, SBP, and FS score significantly increased (P < 0.01) and HF significantly decreased (2 h postoperatively: P < 0.05, 24 h postoperatively, before discharge: P < 0.01). SBP recovered to preoperative values 24 h postoperatively, and HR and FS scores recovered to preoperative values before discharge. However, even before discharge, LF/HF remained significantly higher than preoperative values, and HF remained significantly lower than preoperative values (P < 0.01). Conclusion We observed perioperative stress from multiple perspectives. Circulatory dynamics and psychological status recovered by the day before discharge; however, ANS activity did not. Therefore, evaluating ANS activity may be useful in visualizing potential perioperative stress in pediatric patients.

Formulation and clinical evaluation of carbidopa/levodopa oral solution for the treatment of sepiapterin reductase deficiency.

BACKGROUND: sepiapterine reductase deficiency (SRD) is a rare levodopa (L-dopa)-responsive disorder treated with a combination therapy of controlled-release L-dopa and carbidopa. The currently available formulation of controlled-release carbidopa/L-dopa does not entirely meet the requirements for the long-term therapy in pediatric patients. In fact, administration of a manufactured tablet at a dose intended for adults necessitates its adjustment to the child's needs, as the splitting of the tablet into smaller portions or its dilution in water. It's essential to emphasize that tablets must not be crushed, as this can compromise the controlled-release mechanism and affect the efficacy of the medication. At the moment, commercial liquid formulations are not available. Given these limitations, in house drug preparation in hospitals and community pharmacies is a valid option to ensure the proper therapeutic management of these patients. MATERIALS AND METHODS: we described sample preparation, physical and microbiological analyses, taste testing, and tolerability of a 1:10 ratio carbidopa/L-dopa flavored (mint, raspberry, cacao, berries) and unflavored oral formulation (no sweetening agents were added). We also reported long-term follow-up of two pediatric patients with SRD. RESULTS: we documented the stability for 28 days at 25 °C of the liquid solution. All formulations were well-tolerated, and no adverse events were observed during or after assessing taste and tolerability. The long-term follow up of two patients was characterized by effective symptom control and optimal treatment adherence and compliance. CONCLUSIONS: in-house liquid drug formulations can be a valid option for pediatric patients with SRD. Given the significant impact of taste on medication adherence, the use of flavoring agents in the development of liquid formulations of L-dopa/carbidopa results a very useful strategy to obtain optimal adherence in the pediatric population.

Tailored Sticky Solutions: 3D-Printed Miconazole Buccal Films for Pediatric Oral Candidiasis.

In this research, 3D-printed antifungal buccal films (BFs) were manufactured as a potential alternative to commercially available antifungal oral gels addressing key considerations such as ease of manufacturing, convenience of administration, enhanced drug efficacy and suitability of paediatric patients. The fabrication process involved the use of a semi-solid extrusion method to create BFs from zein-Poly-Vinyl-Pyrrolidone (zein-PVP) polymer blend, which served as a carrier for drug (miconazole) and taste enhancers. After manufacturing, it was determined that the disintegration time for all films was less than 10 min. However, these films are designed to adhere to buccal tissue, ensuring sustained drug release. Approximately 80% of the miconazole was released gradually over 2 h from the zein/PVP matrix of the 3D printed films. Moreover, a detailed physicochemical characterization including spectroscopic and thermal methods was conducted to assess solid state and thermal stability of film constituents. Mucoadhesive properties and mechanical evaluation were also studied, while permeability studies revealed the extent to which film-loaded miconazole permeates through buccal tissue compared to commercially available oral gel formulation. Histological evaluation of the treated tissues was followed. Furthermore, in vitro antifungal activity was assessed for the developed films and the commercial oral gel. Finally, films underwent a two-month drug stability test to ascertain the suitability of the BFs for clinical application. The results demonstrate that 3D-printed films are a promising alternative for local administration of miconazole in the oral cavity.

Exploring Environmental Considerations for Terminally Ill Pediatric Patients in Palliative Care Inpatient Units: A Narrative Review.

Background: The end-of-life experience is significantly influenced by the surrounding environment, emphasizing the importance of exploring built environmental factors in palliative care, especially for pediatric patients. As the majority of end-of-life individuals are elderly or adults, most studies have focused on the environment for this demographic. However, it is essential to recognize that children and adolescents may have distinct needs in this regard. Aim: This narrative review aims to explore the impact of the built environment on pediatric end-of-life patients in inpatient units within palliative care settings. Method: A comprehensive search was conducted across four key databases (PubMed, MEDLINE, PsycINFO, and CINAHL) to identify relevant articles. The screening process commenced with an initial assessment of article titles and abstracts, followed by a thorough examination of full-text studies that met the inclusion criteria. Data synthesis involved thematic analysis facilitated by NVIVO software and informed by the findings extracted from selected literature. Results: The review identified 22 studies meeting inclusion criteria, revealing key insights into environmental considerations in pediatric palliative care. Four themes emerged, highlighting the significance of activities and play environments, accommodation spaces for patients, supportive spaces for families, and outdoor and green spaces. Conclusions: Acknowledging limited research on architectural aspects and reliance on family and staff perspectives, future studies should prioritize understanding pediatric patients' perspectives, particularly adolescents. The study underscores the importance of enhancing environmental design in pediatric palliative care to meet the unique needs of patients and their families.

Antimicrobial susceptibility and virulence gene analysis of Shigella species causing dysentery in Iranian children: Implications for fluroquinolone resistance.

Shigella species significantly impact global health due to their role in diarrheal diseases. A 2019-2022 cross-sectional study on 432 stool samples from pediatric patients in Mashhad, Iran, identified Shigella spp. and tested their susceptibility to 12 antimicrobials by the disk diffusion method. The presence of virulence factors, namely ipaH, virA, stx1, and stx2, as well as plasmid-mediated quinolone resistance (PMQR) genes, including qnrA, qnrB, qnrC, qnrD, and qnrS, were ascertained through the utilization of polymerase chain reaction techniques. Sequencing of 15 isolates detected mutations within quinolone resistance-determining regions (QRDRs) at the gyrA and parC genes, indicating fluoroquinolone (FQ) resistance. 19.2 % (83/432) of stool samples contained Shigella, primarily S. sonnei (77.1 %), followed by S. flexneri (21.6 %) and S. boydii (1.2 %). Most isolates were from children under five (55.4 %). All strains had the ipaH gene, lacked stx1 and stx2, and 86.7 % had virA. High resistance was noted for ampicillin and tetracycline (84.3 % each), trimethoprim-sulfamethoxazole (81.9 %), and azithromycin (60.2 %). 87.1 % of isolates were multidrug-resistant (MDR). The most common PMQR genes were qnrA and qnrS (41 % each). The qnrD gene, prevalent in 36.1 % of cases, is reported in Iran for the first time. The most common PMQR profile was qnrADS (15.7 %). Resistance to nalidixic acid and ciprofloxacin was 45.8 % and 12 %, respectively. The Shigella isolates exhibited mutations in the gyrA (at codons 83, 87, and 211) and parC (at codons 80, 84, 93, 126, 128, 129, and 132) genes. The D87Y mutation in the gyrA gene was the most common in Shigella isolates, occurring in 73 % of cases. The F93S and L132T mutations in the parC gene were unique to this study. Empirical FQ therapy in patients infected with MDR Shigella, possessing PMQR determinants and/or mutations in the QRDRs of gyrA and parC, may escalate the risks of secondary diseases, extended treatment duration, therapeutic failure, and resistance spread. Consequently, the necessity for continuous surveillance and genetic testing to detect FQ-resistant Shigella strains is of paramount importance.

ERCP-Related adverse events in pediatric patients: a 10-years single-site review.

PURPOSE: This retrospective analysis aimed to assess the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) in pediatric patients by examining ERCP-related adverse events (AEs) occurring over a decade at a single center. METHODS: Pediatric patients under 18 years old who underwent ERCP at the Second Hospital of Hebei Medical University from 1/2013 to 11/2023 were included. ERCP-related AEs were defined according to ERCP-related adverse events: European Society of Gastrointestinal Endoscopy (ESGE) Guideline. Clinical data of patients experiencing ERCP-related AEs were obtained from electronic medical records for analysis. RESULTS: Over the past decade, a total of 76 pediatric patients underwent 113 ERCP procedures, including 26 patients who underwent repeat ERCP, totaling 63 procedures. There were 32 males and 44 females, with a median age of 13 years (range 3 years and 5 months-17 years and 9 months). Among all ERCP procedures, 14 (12.4%) were diagnostic and 99 (87.6%) were therapeutic, with a 100% success rate. 16 cases (14.2%) of ERCP-related AEs, all post-ERCP pancreatitis (PEP), were observed, while no other AEs defined by ESGE such as bleeding, perforation, cholangitis, cholecystitis, or sedation-related events were noted. Additionally, 23 cases (20.4%) of ERCP-related AEs not included in the ESGE definition were observed, including post-ERCP abdominal pain in 20 cases (17.7%), post-ERCP nausea and vomiting in 2 cases (1.8%), and unplanned reoperation in 1 case (0.9%). In the 26 cases of pediatric patients who underwent repeat ERCP, we observed that AEs occurred in 15 cases (57.7%) during their initial ERCP, which was much higher than the overall average level. CONCLUSIONS: Post-ERCP abdominal pain and PEP are the most common ERCP-related AEs in pediatric patients, while severe AEs such as bleeding and perforation are rare. The incidence of AEs after initial ERCP in pediatric patients who received repeat ERCP is higher than the overall average level. Based on our center's experience, we believe that ERCP can be safely performed in children over 3 years old with biliary and pancreatic diseases and obtain reliable clinical benefits. However, active monitoring and management of ERCP-related AEs are essential to improve the clinical outcomes of pediatric ERCP.

A novel approach to calculate the required volume of air for bronchial blockers in young children.

INTRODUCTION: Bronchial blocker balloons inflated with small volumes of air increase balloon pressure, involving a risk of airway injury especially in young children. However, there are no established guidelines regarding the appropriate volumes of air required to provide safe bronchial occlusion. METHODS: This study aimed to introduce a novel method for calculating the amount of air required for safe bronchial blocker balloon occlusion for one lung anesthesia in young children. We included 79 pediatric patients who underwent video-assisted thoracoscopic surgery at our hospital. Preoperatively, the balloon pressure and corresponding diameter of 5F bronchial blockers inflated with different volumes of air were measured. Intraoperatively, bronchial diameters measured by computerized tomographic scans were matched to the ex vivo measured balloon diameters. The quality of lung isolation, incidence of balloon repositioning, and airway injury were documented. Postoperatively, airway injury was evaluated through fiberoptic bronchoscopy. RESULTS: Balloon pressure and balloon diameter showed linear and nonlinear correlations with volume, respectively. The median lengths of the right and left mainstem bronchi were median (interquartile range) range: 5.3 mm (4.5-6.3) 2.7-8.15 and 21.8 (19.6-23.4) 14-29, respectively. Occluding the left mainstem bronchus required <1 mL of air, with a balloon pressure of 27 cm H2O. The isolation quality was high with no case of mucosal injury or displacement. Occluding the right mainstem bronchus required a median air volume of 1.3 mL, with a median balloon pressure of 44 cm H2O. One patient had poor lung isolation due to a tracheal bronchus and another developed mild and transient airway injury. CONCLUSION: The bronchial blocker cuff should be regarded as a high-pressure balloon. We introduced a new concept for safe bronchial blocker balloon occlusion for one-lung ventilation in small children.

Assessment of salivary microbiota profile as a potential diagnostic tool for pediatric celiac disease.

The association between oral dysbiosis and celiac disease (CD) remains poorly understood, as does the impact of CD-associated dysbiosis on disease development or exacerbation. This study aims to investigate alterations in salivary microbial composition among children with CD. In this cross-sectional study, saliva samples from 12 children with active CD (A-CD group), 14 children with CD on a gluten-free diet (GFD), and 10 healthy control (HC) children were analyzed using DNA sequencing targeting the 16S ribosomal RNA. Both patients in A-CD and GFD groups showed a significant increase (p = 0.0001) in the Bacteroidetes phylum, while the Actinobacteria phylum showed a significant decrease (p = 0.0001). Notably, the Rothia genus and R.aeria also demonstrated a significant decrease (p = 0.0001) within the both CD groups as compare to HC. Additionally, the control group displayed a significant increase (p = 0.006) in R.mucilaginosa species compared to both CD patient groups. Distinct bacterial strains were abundant in the saliva of patients with active CD, indicating a unique composition of the salivary microbiome in individuals with CD. These findings suggest that our approach to assessing salivary microbiota changes may contribute to developing noninvasive methods for diagnosing and treating CD.

Pediatric High Labial Frenum Management: Utilizing a Diode Laser for the Transformation of the Smile of an Eight-Year-Old Child.

Median diastema is a physiological occurrence that is frequently seen in the maxillary jaw. Therefore, a median diastema has been associated with a wide range of etiological variables, including thumb sucking, supernumerary teeth, tongue thrusting, some dentoalveolar discrepancy, and hypodontia. Patient esthetic and function demands are both negated by the labial frenum's abnormal location in relation to the maxillary anterior teeth, which results in diastema and gingival recession. Lasers are now being used in several fields of dentistry as an alternative to conventional scalpel operations. Frenectomy can be done through the use of electrosurgery, laser surgery, or the classic scalpel technique. This pathological frenum can be very well excised with a diode laser. Due to its applicability, sufficient coagulation, lack of suture requirements, and reduced discomfort and inflammation, the diode laser can be utilized in pediatric dentistry. High-connected midline diastema has remained a subject of debate when it comes to management and the right time to intervene and treat it. Both orthodontists and pediatric dentists agree that frenectomy should not be done after the closure of the orthodontist gap or before the appearance of the permanent canine teeth. However, several conditions, including the child's psychological status, parents' concerns, the closure's unpredictable effects on the future, and the expense of combined therapies, may lead to an early intervention for therapy during the primary or mixed dentition. In this specific scenario, a child who was eight years old underwent a diode laser frenectomy. After seven days, a follow-up examination showed normal position and attachment of the frenum and no signs of infection at the site of surgery.

The Evaluation of the Impact of Antibiotic De-escalation among Paediatric Patients Admitted to Tertiary Care Hospital in Ajman, UAE: A Cross-Sectional Retrospective Observational Study.

BACKGROUND: Antibiotic de-escalation therapy plays a vital role in reducing the risk of bacterial resistance across the globe. This study elucidates the significance, determinants, and outcomes pertaining to Antibiotic De-escalation (ADE). The ADE is acknowledged as a crucial component within Antimicrobial Stewardship Programs (ASPs). The proliferation of antimicrobial-resistant bacteria arises as an anticipated outcome of the extensive utilization of antibiotics, heightening researchers' apprehensions regarding this global challenge. OBJECTIVE: The primary objective of the study was to evaluate the usage of antibiotics in terms of clinical outcomes (re-admission within 30 days and therapy outcomes upon discharge), adverse events, duration of de-escalation, and duration of hospitalizations among pediatric patients admitted to a tertiary care hospital due to various infectious diseases. METHODOLOGY: A retrospective study was conducted during a four-month period, from January 2022 to April 2023, at a tertiary care facility in Ajman, United Arab Emirates. Participants included in this study were based on specific inclusion and exclusion criteria. RESULTS: A total of 200 pediatric records were screened. The majority of participants, accounting for 66.0%, were female, and 54.0% were classified as Arabs in terms of race. The mean age was 7.5 years (± 2.8). The most prevalent symptoms reported were fever (98%), cough (75%), and sore throat (73%). Male participants were more inclined to present with bacterial infections (88.2%) compared to viral infections (3.8%), bacterial and viral co-illnesses (2.5%), or parasitic infections (1.3%) at the time of admission. Regarding clinical outcomes, 27% of patients were readmitted with the same infection type, while 52% did not experience readmission. The analysis also included information on the number of patients within each antibiotic therapy duration category, alongside the mean duration of antibiotic de-escalation in hours with standard deviation (± SD). The statistical significance of these associations was assessed using P-values, revealing a significant relationship (P < 0.0001) between the duration of antibiotic therapy and the time required for antibiotic de-escalation. CONCLUSION: The study's analysis revealed that individuals readmitted to the hospital, irrespective of whether they presented with the same or a different infection type, exhibited prolonged durations of antibiotic de-escalation. This observation underscores the potential influence of the patient's clinical trajectory and the necessity for adjunctive therapeutic interventions on the duration of antibiotic de-escalation.

Dentigerous Cysts in Children: Clinical, Radiological, and Healing Aspects.

Background and Objectives: Dentigerous cysts are one of the most frequent pathologies associated with unerupted or impacted teeth. Such cysts show a male predilection and a preference for the mandibular region. Also, they commonly occur in the second and third decades of life, with only 9% occurring in the first decade. The aim of this work is to apply and study the therapeutic algorithms developed for dentigerous cysts and their outcomes, from the early diagnostic stage to the complete healing phase of pediatric patients diagnosed with this medical condition. Materials and Methods: The study included 19 pediatric patients diagnosed with dentigerous cysts who underwent the enucleation and extraction or conservative attitude of the associated tooth. The bony healing was also followed-up 9 months after the surgery. Results: A higher incidence in the posterior area of the mandible and maxilla was observed, as well as a higher incidence in boys. The 9 months postoperative radiographic assessment showed that the bony defects were completely healed. Conclusions: A thorough understanding of the nature of the lesion backed by a good clinical history and by state-of-the-art radiographic and radiologic examinations can go a long way in helping the surgeon to choose the correct therapeutic approach and to ameliorate the medical condition in the best long-term interest of the young patient. The considered dentigerous cyst cases demonstrated that an early diagnosis and treatment of this pathology is followed by a responsive treatment.

Risk factors for chloral hydrate sedation failure in pediatric patients: a retrospective analysis.

Background: This study aimed to investigate the risk factors for chloral hydrate sedation failure and complications in a tertiary children's hospital in South Korea. Methods: A retrospective analysis of pediatric procedural sedation with chloral hydrate between January 1, 2021, and March 30, 2022, was performed. The collected data included patient characteristics, sedation history, and procedure. Multivariable regression analysis was performed to identify the risk factors for procedural sedation failure and complications. Results: A total of 6691 procedural sedation were included in the analysis; sedation failure following chloral hydrate (50 mg/kg) occurred in 1457 patients (21.8%) and was associated with a higher rate of overall complications compared to those with successful sedation (17.5% [225 / 1457] vs. 6.2% [322 / 5234]; P < 0.001; odds ratio, 3.236). In the multivariable regression analysis, the following factors were associated with increased risk of sedation failure: general ward or intensive care unit inpatient (compared with outpatient); congenital syndrome; oxygen dependency; history of sedation failure or complications with chloral hydrate; procedure more than 60 min; and magnetic resonance imaging, radiotherapy, or procedures with painful or intense stimuli (all P values < 0.05). Factors contributing to the complications included general ward inpatient, congenital syndromes, congenital heart disease, preterm birth, oxygen dependency, history of complications with chloral hydrate, and current sedation failure with chloral hydrate (all P values < 0.05). Conclusions: To achieve successful sedation with chloral hydrate, the patient's sedation history, risk factors, and the type and duration of the procedure should be considered.

Association between adeno-associated virus 2 and severe acute hepatitis of unknown etiology in Japanese children.

INTRODUCTION: Outbreaks of acute hepatitis of unknown etiology (AHUE) in children were reported in Western countries in 2022. Previous studies found that adeno-associated virus 2 (AAV2) and its helper viruses, such as human adenovirus (HAdV) and human herpesvirus-6 (HHV-6), are frequently detected in patients with AHUE. However, the existence of hepatitis associated with AAV2 prior to AHUE outbreaks in 2022 had not yet been investigated. We aimed to investigate the association between AAV2 and pediatric acute hepatitis in Japanese children, as well as the incidence of AAV2-related hepatitis prior to 2022. METHODS: Preserved blood samples obtained from 49 pediatric patients with acute hepatitis between 2017 and 2023 were retrospectively analyzed. Blood samples from 50 children with acute illnesses and 50 children with chronic conditions were used as controls. Viral DNA loads were quantitated using real-time PCR. RESULTS: AAV2 DNA was detected in 12 % (6/49) of acute hepatitis cases but in only one acute illness and none of the chronic-condition control cases. The concentration of AAV2 DNA in the six acute hepatitis cases was higher than that in the acute-illness control case. Co-infection with one or more helper viruses, including HAdV, HHV-6, cytomegalovirus, and Epstein-Barr virus, was observed in five AAV2-positive cases. CONCLUSIONS: Our results indicated the sporadic occurrence of pediatric severe hepatitis associated with AAV2 infection in Japan prior to the AHUE outbreaks in 2022. Our findings suggest that co-infection with AAV2 and helper viruses plays a role in developing severe hepatitis.

Inappropriate treatment of pulmonary aspergillosis caused by Aspergillus flavus in susceptible pediatric patients: a case series.

BACKGROUND: Pulmonary aspergillosis is a prevalent opportunistic fungal infection that can lead to mortality in pediatric patients with underlying immunosuppression. Appropriate and timely treatment of pulmonary aspergillosis can play a crucial role in reducing mortality among children admitted with suspected infections. CASE PRESENTATION: The present study reports three cases of inappropriate treatment of pulmonary aspergillosis caused by Aspergillus flavus in two Iranian pediatric patients under investigation and one Afghan patient. Unfortunately, two of them died. The cases involved patients aged 9, 1.5, and 3 years. They had been diagnosed with pulmonary disorders, presenting nonspecific clinical signs and radiographic images suggestive of pneumonia. The identification of A. flavus was confirmed through DNA sequencing of the calmodulin (CaM) region. CONCLUSION: A. flavus was the most prevalent cause of pulmonary aspergillosis in pediatric patients. Early diagnosis and accurate antifungal treatment of pulmonary aspergillosis could be crucial in reducing the mortality rate and also have significant potential for preventing other complications among children. Moreover, antifungal prophylaxis seems to be essential for enhancing survival in these patients.

The PompeQoL questionnaire: Development and validation of a new measure for children and adolescents with Pompe disease.

Genetic disorders pose great challenges for affected individuals and their families, as they must cope with the irreversible nature of the disease and a life-long dependence on medical assistance and treatment. Children and adolescents dealing with Pompe disease (PD) often struggle to keep up with their peers in physical activities. To gain valuable insights into their subjective experiences and better understand their perception and coping related to daily challenges linked to their condition and treatment, the use of standardized questionnaires is crucial. This study introduces the novel PompeQoL 1.0 questionnaire for children and adolescents with PD, designed for comprehensive assessment of both disease-specific FDH and HRQoL through self- and proxy reports. Content validity was ensured through patients' and parents' involvement at the initial stages of development and in subsequent cognitive debriefing process. Participants found the questionnaire easy to understand, answerable, relevant, and comprehensive. Adjustments based on feedback from patients and their parents improved its utility as a patient- and observer-reported outcome measure. After careful item examination, 52 items were selected, demonstrating moderate to excellent test-retest reliability for most scales and initial evidence for satisfactory construct validity. The PompeQoL questionnaire stands as a valuable screening instrument for both clinical and research purposes. Future research should prioritize additional revisions and larger validation studies, focusing on testing the questionnaire in clinical practice and trials. Nevertheless, the PompeQoL 1.0 stands out as the first standardized measure providing insights into disease-specific FDH and HRQoL among children and adolescents with various forms of PD.
