Acinetobacter is an important nosocomial pathogen causing health care associated infections. It is highly antibiotic resistant gram-negative bacilli. The study was done to determine the prevalence of Acinetobacter species isolated from various clinical samples with their antibiotic susceptibility pattern. To determine the antimicrobial susceptibility pattern of the isolated Acinetobacter species and also the multidrug resistant mechanisms by phenotypic characterization. The retrospective study was carried out in patients diagnosed with Acinetobacter infection in the Microbiology Department, Krishna Institute of Medical Sciences, Krishna Vishwa Vidyapeeth, Deemed To Be University, Karad, a tertiary care hospital, including the clinical departments, during the period of two years from November 2020 till November 2022. Organism identification, biochemical test, antibiotic resistance pattern and phenotypic tests such as ESBL, MBL and Carbapenemase production were performed as per the Clinical and Laboratory Standards Institute (CLSI). The Modified Hodge test (MHT) was performed for Carbapenemase production detection in Acinetobacter species. A total of 150 Acinetobacter species were isolated from clinical samples. Acinetobacter baumannii was the most prevalent species 138 (92%), followed by Acinetobacter lwoffii 10 (7%) and Acinetobacter hemolyticus 2 (1%). The isolates showed highest resistance to Ampicillin 130 (87%) and sensitive to Colistin 113 (75.3%). Most of the isolates of of Acinetobacter baumannii showed maximum ESBL 21(14%) and MBL 75 (93%) production. Modified Hodge test showed positive results in Acinetobacter baumannii, only 11 (7%). The study showed that Acinetobacter baumannii was the most prevalent species showing drug resistance by phenotypic detection methods. At present Acinetobacter is a frequent pathogen in hospital acquired infections in critically ill patients admitted to ICU. The isolates of Acinetobacter species in our study showed resistant to most commonly used antibiotics. The study showed that ESBL production in Acinetobacter was 22 (15%) and MBL 80 (53%). Most Acinetobacter isolates were Multi Drug Resistant (MDR). MDR Acinetobacter is widely increasing due to inappropriate use of antibiotics in healthcare hospital. In our study, detection of carbapenemase by Modified Hodge test was positive in 11 (7%) isolates. [ABSTRACT FROM AUTHOR]

Introduction: Management of lysosomal storage disorders (LSDs) requires periodic visits for medical surveillance and hospitalizations. Management of LSDs may have been adversely impacted during the COVID-19 pandemic. Objective: To identify the factors impacting health care for patients with LSDs during the COVID-19 pandemic. Methods: An observational study was conducted in Mumbai comparing infusion practices and reasons for missed infusions for 15 months before March 2020 versus two phases during the pandemic (April 2020–March 2021 and April 2021–March 2022) in patients receiving intravenous enzyme replacement therapy (ERT) and on oral substrate reduction therapy (SRT). Results: Fifteen patients with LSDs were enrolled. Before the pandemic, 6/13 (46%) were receiving ERT at the study site, 4/13 (31%) at a local hospital, and 3/13 (23%) at home; two were on SRT. The median distance traveled for receiving ERT was 37 km, and 4.4 infusions/patient were missed. From April 2020 to March 2021, two more patients opted for home ERT infusions. The median distance traveled for receiving ERT was 37 km, and 11.6 infusions/patient were missed. From April 2021 to March 2022, one more patient opted for home ERT infusions. The median distance traveled for receiving ERT was 7 km, and 5.6 infusions/patient were missed. The pandemic also affected SRT compliance adversely. For all patients, the cause of disrupted treatment was travel curbs (69%) and fear of getting COVID-19 infection (38%). Conclusions: Treatment of LSDs was disrupted during the pandemic, with an increase in missed ERT infusions and SRT doses. [ABSTRACT FROM AUTHOR]

Porphyrias are a rare group of inborn errors of metabolism due to defects in the heme biosynthetic pathway. The biochemical hallmark is the overproduction of porphyrin precursors and porphyrin species. Afflicted patients present with a myriad of symptoms causing a diagnostic odyssey. Symptoms often overlap with those of common diseases and may be overlooked unless there is heightened clinical suspicion. We are reporting clinical features and diagnostic challenges in four pediatric patients having variegate porphyria, congenital erythropoietic porphyria, acute intermittent porphyria, and erythropoietic protoporphyria (EPP), who presented with diverse multisystem manifestations. This case series illustrates a logical analysis of symptoms and judicious selection of investigations and the role of genotyping in successfully diagnosing porphyrias. [ABSTRACT FROM AUTHOR]

Background and Objectives: Students with borderline intellectual functioning ("slow learners") underperform in all school subjects. The primary objective of this study was to evaluate the self-perceived anxiety symptoms of slow learners. Its secondary objective was to analyze impact of sociodemographic variables on their symptoms. Settings and Design: Cross-sectional single-arm questionnaire-based study was conducted in the learning disability clinic of a public medical college in Mumbai. Subjects and Methods: One hundred slow learners aged ≥8 to <18 years were recruited by non-probability sampling. Their anxiety symptoms scores were measured using the Screen for Child Anxiety Related Disorders-Child version (SCARED-C) instrument. Statistical Analysis: Multivariate regression analysis was performed for determining the "independent" impact that variables had on the SCARED-C ("individual subscales" and "overall") scores. Results: Symptoms of "separation anxiety" were present in 40%, followed by "social anxiety" in 32%, "generalized anxiety" in 31%, "panic" in 26%, "significant school avoidance" in 24%; and "overall anxiety" in 38% of slow learners. Multivariate analysis revealed that: (i) co-occurring attention-deficit/hyperactivity disorder was significantly associated with having panic symptoms (P = 0.040), and, (ii) studying in a Secondary School Certificate or Higher Secondary Certificate educational board-affiliated school was significantly associated with having symptoms of "generalized anxiety," "social anxiety," and "overall anxiety" (P = 0.009, P = 0.026, and P = 0.046, respectively). Conclusions: Many slow learners in our city have symptoms of anxiety disorders and overall anxiety. There is an urgent need to screen them for anxiety disorders to facilitate their optimum rehabilitation. [ABSTRACT FROM AUTHOR]

Aims: The primary objective of the present study was to evaluate the economic burden of limited English proficiency (LEP) by estimating its direct, indirect, and intangible costs. A secondary objective was to assess the impact of variables on the economic burden. Design and Setting: A cross-sectional single-arm descriptive study conducted in a learning disability clinic in a public medical college in Mumbai. Subjects and Methods: The study cases (aged ≥8 years and ≤18 years) were recruited by non-probability sampling. A structured questionnaire was used to interview the parent to collect data related to direct and indirect costs. Intangible cost data were collected by documenting the willingness-to-pay value using the contingent valuation technique. Statistical Analysis Used: A multivariate regression model was used to assess the impact of predictor variables on the costs. Results: The direct, indirect, and intangible costs due to LEP were Indian Rupees (INR) 826,736, 3,828,220, and 1,906,300, respectively. Indirect costs comprised 82.2% of the total costs. Expenditure on tuition and remedial education comprised 39.86% and 14.08% of the indirect and direct costs, respectively. The average annual learning disability clinic costs were INR 2,169,146. The average annual total costs per student were INR 42,102. Higher socioeconomic status was predictive of increased "indirect costs", "total costs", and "intangible costs." Conclusion: LEP is a cost-intensive condition (indirect > intangible > direct costs). Non-medical costs are the costliest component of direct costs. Parental loss of earnings is the costliest component of indirect costs. [ABSTRACT FROM AUTHOR]

Background and Objectives: Students with borderline intellectual functioning ("slow learners") underperform in all school subjects. The primary objective of this study was to evaluate the parental-perceived health-related quality of life (HRQoL) of these students. Its secondary objective was to analyze the impact of sociodemographic variables on their HRQoL. Settings and Design: Cross-sectional single-arm questionnaire-based study was conducted in the learning disability clinic in a public medical college in Mumbai. Subjects and Methods: One hundred parents of slow learners aged 8 to 16 years were recruited by non-probability sampling. Their HRQoL scores were measured using the English DISABKIDS chronic generic module parent (proxy) long-version ("DCGM-37-P") instrument. Statistical Analysis: Multiple regression analysis was carried out for determining the "independent" impact that sociodemographic variables had on a poor facet and total score outcomes. Results: Clinically significant deficits were detected in 4 facets, namely: small deficit in "social inclusion"; medium deficits in "independence", "emotion", and "social exclusion"; and large deficit in "total score". Multivariate analysis revealed that: (i) being an only child predicted a poor "emotion" and "social exclusion" facet score outcomes (P = 0.039 and P = 0.024, respectively); (ii) being a female predicted a poor "social inclusion" facet score outcome (P = 0.022); and, (iii) studying in a single-gender school predicted a poor "limitation" facet score outcome (P = 0.020). Conclusions: Parents of slow learners perceive their psychosocial and total HRQoL to be significantly compromised. There is a need to evaluate the HRQoL of slow learners so that optimum rehabilitation can be facilitated. [ABSTRACT FROM AUTHOR]

Background and Objectives: School students with specific learning disabilities (SpLDs) endure academic difficulties, anxiety, and social maladaptation. The primary objective of the present study was to evaluate the emotional intelligence (EI) abilities of these afflicted students. Its secondary objective was to analyze the impact of socio-demographic variables on their EI abilities. Settings and Design: Cross-sectional single-arm questionnaire-based study was conducted in the Learning Disability clinic in a public medical college in Mumbai. Subjects and Methods: SpLD students studying in class standards VII–IX were recruited by non-probability sampling. Their EI (overall, subscales, and settings) scores were measured using the Four EsScale of Emotional Intelligence-Adolescents (FESEI-A) questionnaire; and compared with Indian norm scores by utilizing the Mann - Whitney U test. To evaluate the unadjusted impact that each of the "variables" had on the FESEI-A scores, linear regression or the Mann-Whitney U test, or the Kruskal-Wallis test, was utilized as applicable. Results: SpLD students had similar "overall" EI abilities as their regular peers. Their EI scores in school setting were significantly lower (P = 0.001), but significantly higher in social setting (P = 0.005). At univariate level, presence of co-occurring attention-deficit/hyperactivity disorder was significantly associated with a lower "school setting" score (P = 0.040). Higher socioeconomic status was significantly associated with a higher "overall" score and "family setting" score (P = 0.023 and P= 0.041, respectively). Conclusions: There is an urgent need to evaluate the EI abilities of SpLD students to identify deficits so that optimum rehabilitation can be facilitated. [ABSTRACT FROM AUTHOR]

Background: The pharmacokinetics of primaquine [PQ] have been the subject of studies in both adults and healthy participants. However, there is no study on its pharmacokinetics in a setting of undernourishment. In India, there is evidence to show considerable malnourishment in children that in turn can affect drug pharmacokinetics. Given that the country is moving towards malaria elimination, the present study was planned with the objective of comparing pharmacokinetics of the drug in undernourished children relative to normally nourished children. Materials and Methods: After Institutional Ethics Committee approval, children of either gender between the ages of 5 and 12 years and smear-positive for Plasmodium vivax malaria were included. Nourishment status was determined using the Indian Academy of Pediatrics classification of protein energy malnutrition based on Khadilkar's growth charts. Twelve children each were enrolled in the two groups. PQ was given in the dose of 0.3 mg/kg/d and blood collections were made at 0, 1, 2, 3, 4, 6, 8 and 24 hours post-dosing. Levels were estimated by high-performance liquid chromatography. Chloroquine in the dose of 25 mg/kg was given over three days along with supportive care. Results: Of the 24 children, there were 17 boys and 7 girls. There was a statistically significant difference in the body weight between the undernourished and the normally nourished children [21.5 ± 5.52 vs. 28.8 ± 8.84, P < 0.05]. PQ levels showed wide inter-individual variation in both groups. No significant difference was seen in any pharmacokinetic parameter between the two groups. Discussion: This study adds to the limited body of evidence on the pharmacokinetics of PQ in children with malaria and indicates that the dosing of primaquine could potentially be independent of the nourishment status.

Aims: The primary objective of this study was to evaluate the economic burden of slow learners (students with "borderline intellectual functioning") by estimating its direct, indirect, and intangible costs. The secondary objective was to assess the impact of variables on the economic burden. Settings and Design: Cross-sectional, single-arm descriptive study. Setting: Learning disability clinic in a public medical college in Mumbai. Materials and Methods: The study cases (age ≥5 - 18 years) were recruited by nonprobability sampling. A structured questionnaire was used to interview the parent to collect data related to direct and indirect costs. Intangible costs data were collected by documenting the willingness-to-pay value using the contingent valuation technique. Statistical Analysis Used: A quantile regression model was used to assess the impact of predictor variables on the costs. Results: The direct, indirect, and intangible costs of slow learners were INR 6,065,915, 10,298,613, and 145,172,800, respectively. Indirect costs comprised 62.9% of the total costs. Expenditure on tuitions, medications, and remedial education comprised 57.38%, 16.18%, and 10.30% of the direct costs, respectively. The average annual total costs of slow learners were INR 3,544,880. The average annual learning disability clinic costs were INR 2,250,194. The average annual total costs per student were INR 57,951. Longer duration of poor school performance was predictive of higher direct and total costs. Conclusion: The economic burden of slow learners is enormous (intangible > indirect > direct costs). Tuitions are the most costly component of direct costs. Parental loss of earnings is the most costly component of indirect costs. [ABSTRACT FROM AUTHOR]

Pulmonary manifestations are seldom recognized as symptoms of storage disorders. The report describes the diagnostic journey in a 30-month-old male infant, born of a third-degree consanguineous marriage referred to our institute as severe persistent asthma. History revealed that the child had progressively worsening breathlessness and persistent dry cough not associated with fever but accompanied by weight loss. On physical examination, there was growth failure, respiratory distress, clubbing, hepatosplenomegaly, and occasional rhonchi. Blood gas revealed hypoxemia which improved with oxygen administration. Plain X-rays and high-resolution computed tomography of the chest showed perihilar alveolar infiltrates and patchy consolidation. The clinicoradiological features did not support a diagnosis of asthma but favored interstitial lung disease (ILD). Bronchoalveolar lavage was performed as a first-tier investigation. It showed periodic acid-Schiff-negative foamy macrophages. The clues of consanguinity, visceromegaly, ILD, and foamy macrophages in the bronchoalveolar fluid prompted consideration of lysosomal storage disorders as the likely etiology. Gaucher disease and Niemann-Pick disease A/B were ruled out by enzyme estimation. Niemann-Pick disease type C was suspected and confirmed by detecting a homozygous mutation in the NPC2 gene. This case serves to caution physicians against labeling breathlessness in every toddler as asthma. It emphasizes the importance of searching for tell-tale signs such as clubbing and extrapulmonary clues which point to a systemic disease such as lysosomal storage disorders as a primary etiology of chronic respiratory symptoms.

A girl in the early adolescent age group presented with multisystem manifestations in the form of periodic fever, recurrent abdominal pain, hypertension, seizure, skin lesions over the chest and gangrene over the left ring and middle fingertips. Her condition had remained undiagnosed for 11 years. On evaluation, she had features of polyarteritis nodosa (PAN) (multiple aneurysms, symmetric sensorimotor peripheral neuropathy, superficial ulcers, digital necrosis, myalgia, hypertension and proteinuria). As childhood PAN is a phenocopy of adenosine deaminase 2 with a different management strategy, whole-exome sequencing was performed, which revealed a pathogenic variant in ADA2 gene. The child was treated with TNF alpha inhibitors and showed improvement in the Paediatric Vasculitis Activity Score. The paper highlights the gratifying consequences of correct diagnosis with disease-specific therapy that ended the diagnostic odyssey, providing relief to the patient from debilitating symptoms and to the family from the financial burden of continued out-of-pocket health expenditure., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2024.

Context: Numerous pathogens (bacteria, viruses, or fungi) can cause childhood pneumonia. The clinical presentations of viral and bacterial pneumonia can be similar. Though viruses are a more common cause as compared to bacteria, antibiotics remain the first line of treatment for pneumonia., Aims: This study was planned to describe the pulmonary histopathological patterns in cases of pediatric pneumonia (age <12 years) at autopsy and aimed to identify the probable etiology and correlate with clinical presentations., Material and Methods: This is a single-center 3-year retrospective descriptive autopsy study. Relevant clinical data was correlated with the postmortem findings. The cases were assigned to one of the following categories based on probable etiology: viral, bacterial, mixed, or others., Results: There were 89 cases with a postmortem diagnosis of pneumonia among 262 autopsied children (34%). Most patients had histological patterns that suggested viral and bacterial etiology in 46 (51.7%) and 27 (30.3%), respectively. A total of 35 out of 46 patients received antibiotics. Twelve cases had mixed viral and bacterial patterns. Antibiotics were also given in the remaining four children (4.5%) with a similar clinical presentation, where a diagnosis of tuberculosis (03 cases) and invasive aspergillosis (01) was made at autopsy., Conclusion: Neither clinical features nor investigations reliably differentiate between viral and bacterial pneumonia. Autopsy has an important role in providing insights into the pathogenesis of pneumonia and suggests inappropriate antibiotic exposure. No prior Indian studies have been performed to compare the clinical and postmortem findings of pneumonia in children., (Copyright © 2024 Copyright: © 2024 Indian Journal of Pathology and Microbiology.)

Purpose: To analyze the outcome of intervention versus observation for vitreous cavity hemorrhage occurring after a 2-month period of blood-free cavity (late postoperative vitreous cavity hemorrhage-POVCH) in eyes operated by vitrectomy for complications of proliferative diabetic retinopathy (PDR)., Methods: This study was a 10-year retrospective, observational, multi-center study involving eight major vitreoretinal surgical centers across India from January 2010 to December 2019. The primary objective of the study was to assess the visual and clinical outcomes of various management approaches for late POVCH. The key secondary objective was to determine the best management option that prevented recurrence. Patients with follow-up of less than 6 months of POVCH management were excluded., Results: The occurrence of late POVCH was studied in 261 eyes. The median time to occurrence was 7 months (range: 2-87) postvitrectomy/silicone oil removal. The majority (58%) experienced a single, nonrecurring POVCH event. Visual acuity outcome was independent of all management approaches (P = 0.179; mean follow-up 20.7 ± 14.1 months). With watchful observation, spontaneous resolution was noted in 83% (60/72 eyes) of eyes in 81.5 days (interquartile range, 169.75). Silicone oil injection was most effective in preventing recurrence (P < 0.001)., Conclusion: The current treatment practice of late POVCH management in PDR suggests that watchful observation for at least 3 months could be as efficacious as any surgical intervention., (Copyright © 2023 Copyright: © 2023 Indian Journal of Ophthalmology.)

Background: To analyze the clinical profile, presentation, possible pathophysiology, and outcomes of central retinal artery occlusion (CRAO) following blunt trauma in pediatric subjects., Methodology: The medical charts of subjects aged 18 years or less with a diagnosis of CRAO following blunt ocular trauma were analyzed retrospectively for demography, details of the trauma, ocular findings, additional imaging reports if any, and final outcome. A Medline search was done (key words like central retinal artery occlusion, blunt trauma, children, pediatric subjects, and adolescents) to gather information available in the literature on the subject., Results: A total of 11 patients (11 eyes), mean age of 14.3 ± 3.4 years, and 100% male preponderance, with an average time duration from trauma to presentation to the hospital of 8.1 days were included. Visual acuity ranged from no light perception (four eyes) to finger count at a 1 m distance. Intraocular pressure was raised in three patients, of which two were suffering from sickle cell disease. In two eyes, the CRAO coexisted with optic nerve avulsion and the cilioretinal artery was spared. Disk pallor was seen in six eyes as early as 12 days from the trauma. None of the cases revealed any bony fracture in the CT scan., Conclusion: CRAO was observed to be an important primary or contributory cause of visual loss in children following blunt trauma, reflex vasospasm being the most common etiology. Early onset disk pallor could suggest an underlying vascular compromise of both retinal and optic disk circulation in addition to direct disk damage., (Copyright © 2023 Copyright: © 2023 Indian Journal of Ophthalmology.)

Ideally, ripe fruits offer appropriate nutritional content and best quality in terms of taste and flavour. Prediction of ripe climacteric fruits acts as the main marketing indicator for quality from the consumer perspective and thus renders it a genuine industrial concern for all the stakeholders of the fruit supply chain. However, the building of fruit-specific individual model for the prediction of ripeness level remains an existing challenge due to the scarcity of sufficient labeled experimental data for each fruit. This paper describes the development of generic AI models based on the similarity in physico-chemical degradation phenomena of climacteric fruits for prediction of 'unripe' and 'ripe' levels using 'zero-shot' transfer learning techniques. Experiments were performed on a variety of climacteric and non-climacteric fruits, and it was observed that transfer learning works better for fruits within a cluster (climacteric fruits) as compared to across clusters (climacteric to non-climacteric fruits). The main contributions of this work are two-fold (i) Using domain knowledge of food chemistry to label the data in terms of age of the fruit, (ii) We hypothesize and prove that the zero-shot transfer learning works better within a set of fruits, sharing similar degradation chemistry depicted by their visual properties like black spot formations, wrinkles, discoloration, etc. The best models trained on banana, papaya and mango dataset resulted in s zero-shot transfer learned accuracies in the range of 70 to 82 for unknown climacteric fruits. To the best of our knowledge, this is the first study to demonstrate the same., (© 2023. The Author(s).)
