Self-nanoemulsifying drug delivery system for nebulization: fabrication and evaluation for systemic delivery of atorvastatin.

The study undertakes the development of an atorvastatin-loaded self-nanoemulsifying drug delivery system (SNEDDS) to improve its bioavailability. The SNEDDS were fabricated using oleic acid, Tween 80, and Span 80 by spontaneous emulsification. The SNEDDS were assessed for their particle size distribution, zeta potential, morphology, drug content, surface tension, viscosity, and drug release. The aerodynamic performance of the SNEDDS was evaluated using an Andersen cascade impactor, while the lipid-lowering potential of the SNEDDS was determined in Wistar rats using the analyzer "Microlab 300." The particle size of the SNEDDS ranged from 36 to 311 nm, with a polydispersity index (PDI) of 0.25-0.40. The zeta potential of the SNEDDS fluctuated from - 29.22 to - 38.26 mV, which declined to - 4.55 mV in the case of F5. The chitosan-coated formulation (F5) exhibited a higher viscosity (22.12 mPa s) and lower surface tension (0.056 dyne/cm) than other formulations (F1-F4). The non-coated formulation exhibited a significantly higher burst drug release, followed by a sustained drug release pattern (p ≤ 0.05) as compared to the coated formulation (F5). The nebulized SNEDDS achieved a dispersed fraction of 87 to 97%, where notably higher aerosol dispersion from F4 was attributed to its smaller particle size and circularity. The inhaled fraction of nebulized SNEDDS was 74-87%. The size of the SNEDDS droplets was the primary determinant affecting the aerodynamic performance of the SNEDDS during nebulization. The chitosan-coated SNEDDS achieved a higher antihyperlipidemic effect than marketed tablets, which shows the suitability of F5 for effective systemic delivery of atorvastatin through the lung.

Linezolid-resistant Enterococcus faecium clinical isolates from Pakistan: a genomic analysis.

BACKGROUND: Linezolid-resistant Enterococcus faecium (LRE) is a global priority pathogen. Thirteen LRE were reported from clinical specimens between November 2021 and April 2023 at two laboratories in Karachi, Pakistan. We aimed to investigate the strain types and genes associated with linezolid resistance among these isolates. Whole genome sequencing (WGS) was performed and analyzed by multilocus sequence typing (MLST). The presence of linezolid resistance genes was identified using ResFinder v4.1.11 and the LRE-finder tool. RESULTS: Twelve isolates belonged to clonal complex 17 (CC17); ST80 (n = 10), ST612 (n = 1) and ST1380 (n = 1). Six isolates showed the presence of optrA gene and G2576T mutations in the 23S rRNA gene, while six showed poxtA and cfr(D) genes. One isolate showed the combination of optrA, cfr(D) and poxtA genes. CONCLUSION: Our findings show the circulation of CC17 sequence types with a known outbreak potential and we identified molecular mechanisms of resistance that were not previously reported from Pakistan.

Role of Proton Beam Therapy in Spinal Chordomas: A Narrative Review of The Literature.

Chordomas are rare malignant neoplasms arising from vestigial remnants of the embryonic notochord. Approximately 55-70% of chordomas develop within the vertebral column. Their affinity to develop within the bones of the axial skeleton and propensity to locally invade and recur makes them challenging candidates for complete surgical excision. Adjuvant therapies are hence necessary to improve outcomes; for which chemotherapy has been observed to be largely ineffective, owing to the tumour being resistant to it. Radiotherapy is the current adjuvant therapy of choice for chordoma management. Over the years, proton beam therapy (PBT) has been the subject of medical attention, given the dosimetric benefits it confers over traditional radiotherapy, allowing more concentrated radiation to be given to the target of interest and reducing damage to surrounding normal tissue. A review of the current literature reveals PBT offers significantly better outcomes when used as an adjuvant to maximal surgical resection rather than as a definitive therapy.

Disparities in age and gender-specific SARS-CoV-2 diagnostic testing trends: a retrospective study from Pakistan.

BACKGROUND: Pakistan reported 1.57 million COVID-19 cases between 2020 and 2022, based on approximately 30.6 million SARS-CoV-2 RT-PCR (reverse-transcription polymerase chain reaction) tests conducted. This study utilized data from one of the largest in-country testing facilities, Aga Khan University Hospital (AKUH) in Karachi, Pakistan, to explore gender and age-related in RT-PCR testing patterns. METHODS: We conducted a retrospective review of SARS-CoV-2 RT-PCR test data extracted from AKUH clinical laboratory records between February 2020 and February 2022. Gender and age distributions were examined in the context of testing patterns across the period. Multivariate regression models assessed independent associations between COVID-19 positivity and key variables. RESULTS: We reviewed 470,249 RT-PCR tests, finding that most tests were in those aged 21-40 years (48.1%). Overall, COVID-19 test positivity was 20.6%. In all, 57.7% were performed for males, predominant amongst those tested across all age groups and waves. Females had significantly lower odds of testing positive for COVID-19 (OR: 0.9; 95% CI: 0.9-1.0). However, when adjusted for gender, age and pandemic phases, the positivity rates between males and females were the same. The odds of a positive result increased significantly with age; individuals aged > 80 years had 2.5 times higher odds of testing positive than those aged 0-10 years (aOR 2.5, 95% CI 2.3-2.7). CONCLUSIONS: The analysis indicates a consistent male dominance in COVID-19 testing, with higher positivity rates in older age groups. Our study highlight the importance of examining demographic characteristics in disease associated data especially, representation of females amongst cohorts.

Risk factors for mortality in hospitalized COVID-19 patients across five waves in Pakistan.

This retrospective cohort study aims to describe the clinical characteristics and outcomes and assess risk factors for mortality across the epidemic waves in hospitalized COVID-19 patients in a major tertiary-care center in Pakistan. A total of 5368 patients with COVID-19, hospitalized between March 2020 and April 2022 were included. The median age was 58 years (IQR: 44-69), 41% were females, and the overall mortality was 12%. Comparative analysis of COVID-19 waves showed that the proportion of patients aged ≥ 60 years was highest during the post-wave 4 period (61.4%) and Wave 4 (Delta) (50%) (p < 0.001). Male predominance decreased from 65.2% in Wave 2 to 44.2% in Wave 5 (Omicron) (p < 0.001). Mortality rate was lowest at 9.4% in wave 5 and highest at 21.6% in the post-wave 4 period (p = 0.041). In multivariable analysis for risk factors of mortality, acute respiratory distress syndrome (ARDS) was most strongly associated with mortality (aOR 22.98, 95% CI 15.28-34.55, p < 0.001), followed by need for mechanical ventilation (aOR 6.81, 95% CI 5.13-9.05, p < 0.001). Other significant risk factors included acute kidney injury (aOR 3.05, 95% CI 2.38-3.91, p < 0.001), stroke (aOR 2.40, 95% CI 1.26-4.60, p = 0.008), pulmonary embolism (OR 2.07, 95% CI 1.28-3.35, p = 0.003), and age ≥ 60 years (aOR 2.45, 95% CI 1.95-3.09, p < 0.001). Enoxaparin use was associated with lower mortality odds (aOR 0.45, 95% CI 0.35-0.60, p < 0.001. Patients hospitalized during Wave 4 (aOR 2.22, 95% CI 1.39-3.56, p < 0.001) and the post-wave 4 period (aOR 2.82, 95% CI 1.37-5.80, p = 0.005) had higher mortality odds compared to other waves. The study identifies higher mortality risk in patients admitted in Delta wave and post-wave, aged ≥ 60 years, and with respiratory and renal complications, and lower risk with anticoagulation during COVID-19 waves.

Colo-colonic intussusception secondary to Burkitt lymphoma with concurrent malignant small bowel mesh adhesion.

Intussusception is a rare presentation in adult population and usually occurs secondary to an underlying pathology. We report an unusual case of a 28-year-old female who developed a colo-colonic intussusception secondary to Burkitt lymphoma which was managed with an extended right hemicolectomy. The case was further complicated by a segment of small bowel with malignant adhesion to a prosthetic mesh requiring resection of the involved segment of small bowel. We have discussed the significance of this case as well as general considerations in the surgical management of adult intussusception.

Prevalence and Associations of Depression in Parents of Children With Congenital Talipes Equinovarus: A Single-Centre Study.

INTRODUCTION: Congenital talipes equinovarus (CTEV) is a congenital deformity that requires weekly visits to the hospital for manipulation and corrective cast application, followed by an intensive bracing regimen requiring multiple visits to the hospital spread over the years. Parents of children with clubfoot are known to undergo a range of negative emotions. The objective of this study was to identify the prevalence of depression and the factors associated with depression in parents of children with idiopathic CTEV. METHODS: This cross-sectional study consecutively enrolled 190 parents of children with idiopathic CTEV undergoing treatment at King George Medical University. Parents with conditions that preclude the assessment of mental status were not included. These conditions include a history of head injury or psychiatric illness, parents with ongoing treatment of psychiatric illness, ongoing chronic illness, chronic neurological disease, and parents with clinically established intellectual disability. Information was recorded on certain parent-related characteristics and certain child-related characteristics. Parent-related information included age and sex of the parent, religion, area of residence, number of children in the family, degree of perceived social support (using the Multidimensional Scale of Perceived Social Support, MSPSS), level of education, socio-economic status, depression subscale score of DASS 21 (Depression, Depression Anxiety, and Stress Scale -21), chronic pain (visual analogue scale, VAS), family history of clubfoot or depression, and level of stress caused by a major life event during the past year using the Presumptive Stressful Life Event Scale (PSLES). Child-related information included the sex of the child, phase of treatment (casting or bracing), limb involvement (unilateral or bilateral), relapse of the deformity, and Pirani score of the deformity. Bivariate analysis and logistic regression were used to identify factors associated with a score ≥10 on the depression subscale of DASS 21. RESULTS: One hundred forty-five subjects were males (76.3%). The mean age of the enrolled parents was 28.47±4.89 years. The mean score on the depression subscale of DASS-21 was 4.87±6.3. Thirty-two parents (16.8%) had a score of ≥10 on the depression subscale of the DASS-21. On bivariate analysis, female sex, being Hindu, having studied up to class 12th, relapse, MSPSS score, and PSLES score were found to be associated with a score ≥10 on the depression subscale of the DASS-21. On logistic regression, female sex, lack of graduate education and above, and MSPSS scores were found to be significantly associated with a score of ≥10 on the depression subscale of the DASS 21 score. CONCLUSION: The prevalence of depression in parents of children with idiopathic clubfoot was 16.8%. Female gender, lack of college education, and the level of perceived social support (MSPSS) are independently associated with a score ≥10 on the depression subscale of DASS 21. We recommend screening parents of children with clubfoot and referring those with abnormal scores to a psychiatrist for a confirmed diagnosis.

pH-Sensitive Hydrogels Fabricated with Hyaluronic Acid as a Polymer for Site-Specific Delivery of Mesalamine.

Hydrogels with the main objective of releasing mesalamine (5-aminosalicylic acid) in the colon in a modified manner were formulated in the present work using a free-radical polymerization approach. Different ratios of hyaluronic acid were cross-linked with methacrylic and acrylic acids using methylenebis(acrylamide). The development of a new polymeric network and the successful loading of drug were revealed by Fourier transform infrared spectroscopy. Thermogravimetric analysis demonstrated that the hydrogel was more thermally stable than the pure polymer and drug. Scanning electron microscopy (SEM) revealed a rough and hard surface which was relatively suitable for efficient loading of drug and significant penetration of dissolution medium inside the polymeric system. Studies on swelling and drug release were conducted at 37 °C in acidic and basic conditions (pH 1.2, 4.5, 6.8, and 7.4, respectively). Significant swelling and drug release occurred at pH 7.4. Swelling, drug loading, drug release, and gel fraction of the hydrogels increased with increasing hyaluronic acid, methacrylic acid, and acrylic acid concentrations, while the sol fraction decreased. Results obtained from the toxicity study proved the formulated system to be safe for biological systems. The pH-sensitive hydrogels have the potential to be beneficial for colon targeting due to their pH sensitivity and biodegradability. Inflammatory bowel disease may respond better to hydrogel treatment as compared to conventional dosage forms. Specific amount of drug is released from hydrogels at specific intervals to maintain its therapeutic concentration at the required level.

Prevalence and predictors of mitral annular disjunction and ventricular ectopy in mitral valve prolapse.

BACKGROUND: Mitral annular disjunction (MAD) is associated with ventricular arrhythmia in mitral valve prolapse (MVP). The proportional risk from MAD and other predictors of ventricular arrhythmia in MVP has not been well characterized. OBJECTIVE: This study aimed to identify predictors of complex or frequent ventricular ectopy (cfVE) in MVP and to quantify risk of cfVE and mortality in MVP with MAD. METHODS: We studied 632 adult patients with MVP on transthoracic echocardiography at the University of North Carolina Medical Center from 2016 to 2019 (median age, 64 [interquartile range, 52-74] years; 52.7% female; 16.3% African American). Resting and ambulatory electrocardiograms were used to identify cfVE. RESULTS: MAD was present in 94 (14.9%) patients. Independent associations of MAD were bileaflet prolapse (odds ratio [95% CI], 4.25 [2.47-7.33]; P < .0001), myxomatous valve (2.17 [1.27-3.71]; P = .005), absence of hypertension (2.00 [1.21-3.32]; P = .007), electrocardiogram inferior or lateral lead T-wave inversion (2.07 [1.23-3.48]; P = .006), and female sex (1.99 [1.21-3.25]; P = .006). cfVE was frequent with MAD (39 [41.5%] vs 93 [17.3%] without; P < .0001). Independent cfVE predictors were MAD (hazard ratio [95% CI], 2.23 [1.47-3.36]; P = .0001), bileaflet prolapse (1.86 [1.25-2.76]; P = .002), heart failure (1.79 [1.16-2.77]; P = .009), lower left ventricular ejection fraction (0.14 [0.03-0.61]; P = .009), coronary artery disease (1.60 [1.05-2.43]; P = .03), and inferior or lateral lead T-wave inversion (1.51 [1.03-2.22]; P = .03). After a median of 40 (33-48) months, there was increased mortality with MAD (P = .04). CONCLUSION: MAD in MVP is associated with bileaflet or myxomatous MVP, absence of hypertension, T-wave inversion, and female sex. There is increased cfVE and mortality with MAD, highlighting the need for closer follow-up of these patients.

By identifying accelerated cardiac aging from the ECG, AI offers novel insights into risk assessment and prevention.

Human Immunodeficiency Virus Type-1 Genetic Diversity and Drugs Resistance Mutations among People Living with HIV in Karachi, Pakistan.

The human immunodeficiency virus type-1 epidemic in Pakistan has significantly increased over the last two decades. In Karachi, Pakistan, there is a lack of updated information on the complexity of HIV-1 genetic diversity and the burden of drug resistance mutations (DRMs) that can contribute to ART failure and poor treatment outcomes. This study aimed to determine HIV-1 genetic diversity and identify drug-resistance mutations among people living with HIV in Karachi. A total of 364 HIV-positive individuals, with a median age of 36 years, were enrolled in the study. The HIV-1 partial pol gene was successfully sequenced from 268 individuals. The sequences were used to generate phylogenetic trees to determine clade diversity and also to assess the burden of DRMs. Based on the partial pol sequences, 13 distinct HIV-1 subtypes and recombinant forms were identified. Subtype A1 was the most common clade (40%), followed by CRF02_AG (33.2%). Acquired DRMs were found in 30.6% of the ART-experienced patients, of whom 70.7%, 20.7%, and 8.5% were associated with resistance to NNRTIs, NRTIs, and PIs, respectively. Transmitted DRMs were found in 5.6% of the ART-naïve patients, of whom 93% were associated with resistance against NNRTIs and 7% to PIs. The high prevalence of DRMs in ART-experienced patients poses significant challenges to the long-term benefits and sustainability of the ART program. This study emphasizes the importance of continuous HIV molecular epidemiology and drug resistance surveillance to support evidence-based HIV prevention, precise ART, and targeted AIDS care.

Shift in SARS-CoV-2 variants of concern from Delta to Omicron was associated with reduced hospitalizations, increased risk of breakthrough infections but lesser disease severity.

BACKGROUND: COVID-19 epidemiology changed with the emergence of SARS-CoV-2 variants of concern (VOC). Pakistan administered mostly inactivated vaccines. We investigated the association between VOC and breakthrough infections in a mixed-vaccination-status population of Karachi. METHODS: We investigated SARS-CoV-2 VOC tested in 392 respiratory specimens collected between May and December 2021. Data for age, sex, hospital admission, vaccinations, together with CT values of the diagnostic PCR test were analyzed. RESULTS: The median age of COVID-19 cases tested was 40 (27-57) years and 43.4% were female. Delta variants were most common (56.4%) followed by Alpha (15.9%), Omicron (12.2%), Beta/Gamma (11.3%), and others (4.3%). Eighteen percent of cases were hospitalized whereby, predominant VOC were Beta/Gamma (40.8%), Alpha (35.2%) and Delta (22.5%). Overall, 55.4% of individuals were fully vaccinated, 7.4% were partially vaccinated and 37.2% were unvaccinated. Most (74.6%) inpatients were unvaccinated. Vaccines comprised inactivated (85.34%), single-shot vector (8.62%), two-shot vector (3.02%) and mRNA (3.02%) types. Omicron variants showed lower viral loads as compared to Alpha, Beta/Gamma, and Delta (p = 0.017). The risk of infection with Delta and Omicron variants was higher, 8 weeks after vaccination. The majority of those with breakthrough infections after receiving inactivated vaccines acquired COVID-19 within 4 months of vaccination. CONCLUSION: Our data highlights the shifting of VOC from Delta to Omicron during 2021 and that COVID-19 vaccinations reduced both hospitalizations and viral transmission. It informs on the increased risk of breakthrough infection within 8 weeks of vaccination, indicating the need for booster vaccinations.

The Effect of Vitamin D Deficiency as a Risk Factor of Early Fragmentation in Legg-Calve-Perthes Disease: A Prospective Study.

INTRODUCTION: Legg-Calve-Perthes disease (LCPD) is a disorder involving the hips in young children of preschool and school-going age groups, more common in 4-8 years. The insufficient blood supply to the femoral head is the main reason behind various etiologic theories. Multiple factors affect the natural progression of the disease. The natural progression of the disease involves early avascular necrosis, fragmentation, reconstitution, and healed stages. In the fragmentation stage, the bony epiphysis begins to fragment, and the subchondral radiolucent zone (crescent sign) is the result of a subchondral stress fracture, which later on determines the extent of a necrotic fragment of the femoral head. These changes later contribute to changes in the shape of the femur head and the extent of deformity. As vitamin D plays a vital role in the onset of the fragmentation stage, we conducted a study to assess the effect of vitamin D deficiency as a risk factor for early fragmentation in Legg-Calve-Perthes disease. METHODS: In our study, 50 patients aged 4-12 years were examined over three years and classified according to Catterall and Herring's lateral pillar classification; the length of the fragmentation stage and the vitamin D level were considered. A vitamin D level of less than 20 ng/mL was labeled as the deficient group, 20-30 ng/mL as the insufficient group, and more than 30 ng/mL as the sufficient (normal) group. RESULTS: The critical fragmentation stage was significantly longer (more than 12 months) in vitamin D deficiency (34%), leading to a higher risk of deformity and extrusion of the femoral head, which led to higher rates of surgical intervention and containment procedures. CONCLUSION: The fragmentation stage is critical in the course of LCPD. Vitamin D levels play a vital role in predicting the prognostic of LCPD, and it should be measured in all patients of LCPD. Patients with normal vitamin D levels have a comparatively shorter fragmentation stage duration than patients with insufficient or deficient levels, leading to a lesser duration of femoral head damage.

Isolated Bilateral Upper Limb Amelia - A Rare Case Report.

Introduction: Congenital upper limb amelia is one of the extremely rare conditions. It is defined as a complete absence of upper limbs. It may present as isolated or with other associated anomalies. Case Report: We present a case of a 2-year-old male child with congenital complete absence of bilateral upper limb. This male child was born after four female children. With the advancement in modern-era prenatal diagnostic facilities and a better understanding of fetal-maternal drug pharmacology, such cases are rare entity. Conclusion: Amelia is a very rare and challenging situation for clinicians. Regular prenatal checkup and knowledge of maternal and fetal drug interactions during pregnancy are key factors for prevention.

Bilateral Van Neck-Odelberg Disease: A Case Report.

Van Neck-Odelberg disease, also known as ischiopubic osteochondritis, is a rare cause of buttock or groin pain in the pediatric age group. The challenge in its diagnosis is due to its radiologic similarity. Ischiopubic synchondrosis occurs in childhood and is seen before the fusion of the pubis and ischium. With the advancement of age toward skeletal maturity, ischiopubic synchondrosis reduces in size and gradually vanishes due to synostosis or bony union. Here, we report the case of a 13-year-old girl who came to our outpatient department with complaints of bilateral groin pain for one year. After a thorough evaluation, she was diagnosed with a case of bilateral Van Neck-Odelberg disease, or ischiopubic osteochondritis, and conservative management was planned. Closure of ischiopubic synchondrosis varies with age and is usually finished before puberty. In a typical scenario, such fusion of the pubis and ischium does not lead to any clinical symptoms. However, in a few instances, children may experience some pain in the groin, hip, or gluteal region, which results in restricted movements at the hip joint and can lead to limping while walking. Van Neck-Odelberg disease is rare in children, causing pain in the groin region. As it is a rare condition, diagnosis is often missed. The radiological appearance suggests many differential diagnoses, such as a stress fracture, neoplasm, or infection. Prompt diagnosis and treatment can relieve the symptoms.

A Novel Approach of Polyvinyl Alcohol/Acrylic Acid Based Hydrogels for Controlled Delivery of Diclofenac Sodium.

AIM AND OBJECTIVE: The aim of this study was to prepare polyvinyl alcohol/acrylic acid (PVA/AA) hydrogels for the controlled release of diclofenac sodium and to develop PVA/AA hydrogels as controlled release carriers to overcome not only the side effects of diclofenac sodium but also sustain its release for an extended period. BACKGROUND: Diclofenac sodium is employed for relieving pain and fever. The half-life of diclofenac sodium is very short (1-2 h). Hence, multiple intakes of diclofenac sodium are required to maintain a constant pharmacological action. Multiple GI adverse effects are produced as a result of diclofenac sodium intake. METHOD: A free radical polymerization technique was used for crosslinking PVA with AA in the presence of APS. EGDMA was used as a cross-linker. FTIR and XRD confirmed the preparation and loading of the drug by prepared hydrogels. An increase in the thermal stability of PVA was shown by TGA and DSC analysis. Surface morphology was investigated by SEM. Similarly, water penetration and drug loading were demonstrated by porosity and drug loading studies. The pH-sensitive nature of PVA/AA hydrogels was investigated at different pH values by swelling and drug release studies. RESULTS: The development and drug loading of PVA/AA hydrogels were confirmed by FTIR and XRD analysis. TGA and DSC indicated high thermal stability of prepared hydrogels as compared to unreacted PVA. SEM indicated a hard and compact network of developed hydrogels. The swelling and drug release studies indicated maximum swelling and drug release at high pH as compared to low pH values, indicating the pH-sensitive nature of prepared hydrogels. Moreover, we demonstrated that drug release was sustained for a prolonged time in a controlled pattern by prepared hydrogels by comparing the drug release of the developed hydrogels with the commercial product Cataflam. CONCLUSION: The results indicated that prepared PVA/AA hydrogels can be used as an alternative approach for the controlled delivery of diclofenac sodium.

A Rare Case of Fungal Osteomyelitis of the Distal Tibia in a Pediatric Patient.

Staphylococcus aureus infection is the most common cause of osteomyelitis. Over 100,000 fungal species have been described; only 150 are pathogenic to humans. These opportunistic infections frequently enter the body due to a decrease in host defense or through an invasive gateway, such as a dental extraction or skin discontinuity due to trauma. Symptoms and radiological examination often mimic those of other etiologies, which can lead to substantial delays in treatment. Our case is a 13-year-old healthy boy with no history of immune incompetency who presented to us with complaints of pain and swelling over his left ankle and leg with an on-and-off history of fever for 15 days. Based on his history and examination, he is diagnosed as having sub-acute osteomyelitis of the distal tibia with septic arthritis. The bacterial culture has no growth; however, the potassium hydroxide mount came positive for fungal elements having hyphae and pseudohyphae, and the fungal culture came positive for Candida. Management of fungal infections is challenging as they have infrequent involvement in bones. Fungal osteomyelitis is considered a rare entity in the literature, and the current case is studied for the management and diagnosis of a rare variant of osteomyelitis in the pediatric population. The treatment guidelines vary based on the identified organism and the duration of treatment. Debridement of fungal osteomyelitis or septic arthritis includes removing sinus tracts, evaluation for squamous cell carcinoma, bony and soft-tissue debridement, and antibiotic or antifungal bead placement. The spectrum of osteomyelitis ranges from Staphylococcus aureus organisms to tumors; therefore, it is necessary to investigate every spectrum of the disease, and fungal infections should be considered differential even though they are a rare entity. Early diagnosis, surgical debridement, and proper antifungal treatment based on fungal species lead to better clinical outcomes and results.

Health-Related Quality of Life in Children and Adolescents With Congenital Adrenal Hyperplasia: A Systematic Review and Meta-Analysis.

OBJECTIVE: To conduct a systematic review (SR) and meta-analysis (MA) on health-related quality-of-life (QoL) and associated factors among children/adolescents with congenital adrenal hyperplasia (CAH). METHOD: Following registration in the PROSPERO International Prospective Register of Systematic Reviews(reg no: CRD42022313389), Google Scholar, PubMed, LILACS, Cochrane, and Scopus databases were searched up to March 5, 2022, using predefined search strategy/MESH terms to identify original studies describing/assessing self-reported/parent-reported health-related QoL in patients with CAH ≤21 years. Methodological quality was assessed by Newcastle-Ottawa Quality Assessment Scale (NOS), and heterogeneity by I2 statistics. MA assessed mean difference (MD) in QoL between children/adolescents with CAH and healthy children/adolescents. RESULTS: Among 1308 publications, the 12 studies eligible for the SR (CAH n = 781) showed NOS scales of 3 to 7/9, and the 6 eligible for MA (CAH n = 227) showed moderate-considerable heterogeneity. MA showed that parent-reported psychosocial QoL (MD 9.9 [-12.6,7.3], P ≤ .001) {consisting of school (MD 7.4[-12.2, -2.5], P = .003), emotional (MD 5.6 [-10.2, -0.9], P = .02) and social domains (MD 4.3 [-8.1, -0.5], P = .03), and self-reported school domain QoL (MD 8.5 [-15.9, -1.2], P = .02) was lower in children/adolescents with CAH while parent-reported and self-reported physical QoL were similar to controls.Factors associated with lower QoL among children/ adolescents with CAH included poor disease control, poor medication compliance, and complications including hyperpigmentation, virilization, hypertension, hospital admission, and urinary incontinence. CONCLUSION: Based on available data, children/adolescents with CAH had preserved physical QoL but impaired psychosocial QoL, especially in the school domain. Factors associated with lower QoL included poor disease control and disease/treatment-related complications. There is a need for further high-quality research that investigates the relationship between disease control, provision of psychosocial support, and improvement in QoL in children/adolescents with CAH.
