Abstract
OBJECTIVE To describe the rare complication of cerebral pseudoaneurysm formation following stereotactic electroencephalography (sEEG) lead implantation in children. METHODS A retrospective chart review of all pediatric patients undergoing sEEG procedures between 2015 and 2020 was performed. Cases of pseudoaneurysm were identified and reviewed. RESULTS Cerebral pseudoaneurysms were identified in two of 58 total cases and 610 implanted electrodes. One lesion was detected 1 year after sEEG explantation and required craniotomy and clipping. The other was detected 3 months post-explantation and underwent coil embolization. Neither patient had any neurologic deficits associated with the pseudoaneurysm before or after treatment. CONCLUSIONS Pseudoaneurysm formation post-sEEG explantation is rare and likely underreported. Routine, post-explantation/treatment imaging is warranted to detect this rare but potentially lethal complication.

Abstract
INTRODUCTION Technology-based exercise is gaining attention as a promising strategy for increasing physical activity (PA) in older adults with cancer (OACA). However, a comprehensive understanding of the interventions, their feasibility, outcomes, and safety is limited. This scoping review (1) assessed the prevalence and type of technology-based remotely delivered exercise interventions for OACA and (2) explored the feasibility, safety, acceptability, and outcomes in these interventions. METHODS Studies with participant mean/median age ≥ 65 reporting at least one outcome measure were included. Databases searched included the following: PubMed, CINAHL, Embase, Cochrane Library Online, SPORTDiscus, and PsycINFO. Multiple independent reviewers completed screening and data abstractions of articles in English, French, and Spanish. RESULTS The search yielded 2339 citations after removing duplicates. Following title and abstract screening, 96 full texts were review, and 15 were included. Study designs were heterogeneous, and sample sizes were diverse (range 14-478). The most common technologies used were website/web portal (n = 6), videos (n = 5), exergaming (n = 2), accelerometer/pedometer with video and/or website (n = 4), and live-videoconferencing (n = 2). Over half (9/15) of the studies examined feasibility using various definitions; feasibility outcomes were reached in all. Common outcomes examined include lower body function and quality of life. Adverse events were uncommon and minor were reported. Qualitative studies identified cost- and time-savings, healthcare professional support, and technology features that encourage engagement as facilitators. CONCLUSION Remote exercise interventions using technology appear to be feasible and acceptable in OACA. IMPLICATIONS FOR CANCER SURVIVORS Some remote exercise interventions may be a viable way to increase PA for OACA.

Abstract
Malformations of cortical development (MCD) are neurological conditions involving focal disruptions of cortical architecture and cellular organization that arise during embryogenesis, largely from somatic mosaic mutations, and cause intractable epilepsy. Identifying the genetic causes of MCD has been a challenge, as mutations remain at low allelic fractions in brain tissue resected to treat condition-related epilepsy. Here we report a genetic landscape from 283 brain resections, identifying 69 mutated genes through intensive profiling of somatic mutations, combining whole-exome and targeted-amplicon sequencing with functional validation including in utero electroporation of mice and single-nucleus RNA sequencing. Genotype-phenotype correlation analysis elucidated specific MCD gene sets associated with distinct pathophysiological and clinical phenotypes. The unique single-cell level spatiotemporal expression patterns of mutated genes in control and patient brains indicate critical roles in excitatory neurogenic pools during brain development and in promoting neuronal hyperexcitability after birth.

Abstract
In analyzing the neural correlates of naturalistic and unstructured behaviors, features of neural activity that are ignored in a trial-based experimental paradigm can be more fully studied and investigated. Here, we analyze neural activity from two patients using electrocorticography (ECoG) and stereo-electroencephalography (sEEG) recordings, and reveal that multiple neural signal characteristics exist that discriminate between unstructured and naturalistic behavioral states such as “engaging in dialogue” and “using electronics”. Using the high gamma amplitude as an estimate of neuronal firing rate, we demonstrate that behavioral states in a naturalistic setting are discriminable based on long-term mean shifts, variance shifts, and differences in the specific neural activity’s covariance structure. Both the rapid and slow changes in high gamma band activity separate unstructured behavioral states. We also use Gaussian process factor analysis (GPFA) to show the existence of salient spatiotemporal features with variable smoothness in time. Further, we demonstrate that both temporally smooth and stochastic spatiotemporal activity can be used to differentiate unstructured behavioral states. This is the first attempt to elucidate how different neural signal features contain information about behavioral states collected outside the conventional experimental paradigm.

Abstract
Iron-sulfur cluster proteins are involved in critical functions for gene expression regulation and mitochondrial bioenergetics including the oxidative phosphorylation system. The c.215G>A p.(Arg72Gln) variant in NFS1 has been previously reported to cause infantile mitochondrial complex II and III deficiency. We describe three additional unrelated patients with the same missense variant. Two infants with the same homozygous variant presented with hypotonia, weakness and lactic acidosis, and one patient with compound heterozygous p.(Arg72Gln) and p.(Arg412His) variants presented as a young adult with gastrointestinal symptoms and fatigue. Skeletal muscle biopsy from patients 1 and 3 showed abnormal mitochondrial morphology, and functional analyses demonstrated decreased activity in respiratory chain complex II and variably in complexes I and III. We found decreased mitochondrial and cytosolic aconitase activities but only mildly affected lipoylation of pyruvate dehydrogenase and 2-oxoglutarate dehydrogenase enzymes. Our studies expand the phenotypic spectrum and provide further evidence for the pathogenicity and functional sequelae of NFS1-related disorders with disturbances in both mitochondrial and cytosolic iron-sulfur cluster containing enzymes.

Abstract
Poultry industry is expanding rapidly and producing million tons of feather waste annually. Massive production of keratinaceous byproducts in the form of industrial wastes throughout the world necessitates its justified utilization. Chemical treatment of keratin waste is proclaimed as an eco-destructive approach by various researchers since it generates secondary pollutants. Keratinase released by a variety of microbes (bacteria and fungi) can be used for the effective treatment of keratin waste. Microbial degradation of keratin waste is an emerging and eco-friendly approach and offers dual benefits, i.e., treatment of recalcitrant pollutant (keratin) and procurement of a commercially important enzyme (keratinase). This study involves the isolation, characterization, and potential utility of fungal species for the degradation of chicken-feather waste through submerged and solid-state fermentation. The isolated fungus was identified and characterized as Aspergillus (A.) flavus. In a trial of 30 days, it was appeared that 74 and 8% feather weight was reduced through sub-merged and solid-state fermentation, respectively by A. flavus. The pH of the growth media in submerged fermentation was changed from 4.8 to 8.35. The exploited application of keratinolytic microbes is, therefore, recommended for the treatment of keratinaceous wastes to achieve dual benefits of remediation.

Abstract
BACKGROUND Prostate cancer (PC) and its treatments lead to significant acute, chronic, or latent adverse effects that result in declines in patients' physical functions, quality of life and reduced sense of masculinities. Robust evidence shows that physical activity (PA) can improve many health outcomes in men with PC; however, less is known about the facilitators, preferences, and barriers to PA engagement in this population. The purpose of this scoping review is to document the nature and extent of literature related to these aspects of PA participation among men with PC. METHODS We conducted a scoping review of PA among men with PC. Databases searched included Medline, CINAHL, Embase, Rehabilitation & Sports Medicine Source, and SportDiscus from inception to June 30, 2020. Multiple reviewers were used in all screening and data abstractions. RESULTS The search yielded 2788 individual citations after duplicates were removed. Following title and abstract screening, 129 underwent full-text review, and 46 articles were included. Quantitative data related to our research question showed that structured group exercise was the most commonly reported facilitator/preference among men with PC, whereas treatment-related effects and lack of time are the most common barriers. In terms of qualitative data, the most prominent theme noted related to masculinities and gender-specific needs within the context of having PC. CONCLUSION Men with PC have unique facilitators and barriers concerning PA. More work is needed from the research and clinical practice perspectives to enable this population to engage and remain in regular PA.

Abstract
AbstractDiagnosing anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis clinically can be challenging. There is a growing interest in identifying specific electroencephalographic features to help guide early management. A retrospective chart review was conducted of pediatric patients admitted to Rady Children's Hospital between January 1, 2010 and April 1, 2017. We included patients with the diagnosis of encephalitis who underwent continuous video electroencephalogram (VEEG) for at least 12 hours, and presented with less than 14 days of symptoms. We compared the electroencephalographic features of non-rapid eye movement (NREM) sleep between patients with antibody confirmed anti-NMDAR encephalitis and patients with encephalitis from other etiologies. We identified seven patients who met our inclusion criteria, five of whom were diagnosed with anti-NMDAR encephalitis. Four of the five patients had a significant reduction in NREM sleep, while one patient had increased NREM sleep associated with clinical catatonia and hypersomnolence. Sleep was preserved in the two cases of nonimmune mediated encephalitis. Our results suggest that a prolonged VEEG to capture sleep coupled with clinical features can aid in early diagnosis and treatment of anti-NMDAR encephalitis, often before confirmatory antibody testing is available.

Abstract
Telehealth's first literature reference is an article in 1879 in the Lancet about using the telephone to reduce unnecessary office visits (Institute of Medicine & Board on Health Care Services, 2012). However, providers have been slow to adopt telehealth into their clinical practice secondary to barriers such as cost and reimbursement (Kane and Gillis, 2018) [2]. The advent of shelter in place orders combined with the ongoing need defined by the Centers for Medicare & Medicaid Services (CMS) Administrator Seema Verma "for all Americans, and particularly vulnerable populations who are at heightened risk, to be able to access their providers" has resulted in the rapid implementation of telehealth across multiple specialties. The goal of this paper is to provide a practical framework for translating quality care in epilepsy as defined by the American Academy of Neurology (AAN) guidelines into a virtual care environment. We will also discuss the use and limitations of point of care testing in epilepsy management.

Abstract
AbstractThere is scarce evidence in review of the available literature to support a clear and superior model for the transition of care for epilepsy patients from pediatric to adult centers. Anecdotally, there is a common perception that families are reluctant to make this change and that the successful transition of care for epilepsy can be a challenge for patients, families, and physicians. As part of the effort to prepare the patient and family for the adult model of care, several treatment issues should be addressed. In this article, we discuss the specific challenges for physicians in transition of care for epilepsy patients from a pharmacological standpoint, which include differences in metabolism and pharmacodynamics that can impact tolerability or efficacy of antiepileptic medications, lifestyle changes affecting medication compliance and seizure control, acquired adult health conditions necessitating new medications that may result in adverse drug interactions, and adult neurologists' potential lack of familiarity with certain medications typically used in the pediatric epilepsy population. We offer this as a guide to avoid one of the many possible pitfalls when epilepsy patients transition to adult care.

Abstract
PURPOSE This update of our 2016 systematic review answers the following questions: (1) How often do older adults with cancer fall? (2) What are the predictors for falls? (3) What are the rates and predictors of injurious falls? (4) What are the circumstances and outcomes of falls? (5) How do falls in older patients affect subsequent cancer treatment? and a new research question, (6) Which fall reduction interventions are efficacious in this population? METHODS MEDLINE, PubMed, CINAHL, and Embase were searched (September 2015-January 25, 2019). Eligible studies included clinical trials and cohort, case-control, and cross-sectional studies published in English in which the sample (or subgroup) included adults aged ≥ 60, with cancer, in whom falls were examined as an outcome. RESULTS A total of 2521 titles were reviewed, 67 full-text articles were screened for eligibility, and 30 new studies were identified. The majority involved the outpatient setting (n = 19) utilizing cross-sectional method (n = 18). Sample size ranged from 21 to 17,958. Fall rates ranged from 1.52 to 3.41% per 1000 patient days (inpatient setting) and from 39%/24 months to 64%/12 months (outpatient setting). One out of the 6 research questions contributed to a new finding: one study reported that 1 in 20 older patients experienced impact on cancer treatment due to falls. No consistent predictors for falls/fall injuries and no studies on fall reduction interventions in the geriatric oncology setting were identified. CONCLUSION This updated review highlights a new gap in knowledge pertaining to interventions to prevent falls. Additionally, new knowledge also emerged in terms of impact of falls on cancer treatment; however, further research may increase generalizability. Falls and fall-related injuries are common in older adults with cancer and may affect subsequent cancer treatment. Further studies on predictors of falls, subsequent impacts, and fall reduction in the oncology setting are warranted.

Abstract
Due to shorter shelf life and inadequate postharvest facilities, every year a huge loss of
banana occurs in Bangladesh. An effective postharvest practice can reduce the spoilage
rate as well as can extend the shelf life of banana. In this context, this current study was
conducted to assess the effect of banana peel extract (BPE) on shelf life and quality
characteristics of ripe banana (cultivar: sagar). Four types of ripe banana samples were
prepared and were assessed to find the changes of different physico-chemical parameters
like weight loss, color, flavor, firmness, total soluble solid (TSS), pH and spoilage rate.
Storage study showed that shelf life of banana can be extended around 2-3 days by
spraying BPE on the outer surface of ripe banana. Bananas without treatment were
completely spoiled on the fifth day of storage whereas 31.25, 50.00 and 69.23% samples
were spoiled on that day in case of bananas treated with BPE of 80% ethanol, distilled
water and acetone respectively. The best retention of color, flavor and texture was found
for samples treated with BPE of 80% ethanol. Finally, this study revealed that banana peel
can be used as a potential source to preserve banana with extended shelf stability

Abstract
Neonatal sepsis is one of the most common reasons for admission to neonatal units in developing countries. It is also a major cause of mortality in both developed and developing countries. The type and pattern of organisms that cause neonatal sepsis changes over time and vary from one hospital to another hospital, even in the same country. In addition the causative organisms have developed increased drug resistance for the last two decades. Maternal, neonatal and environmental risk factors have contributed for the development of sepsis. To study the risk factors, causative organism and bacterial sensitivity pattern in cases of neonatal sepsis. This cross-sectional study was conducted over a period of six months. The study included 100 patients admitted at the neonatal ward of Department of Pediatrics, Community Based Medical College Bangladesh, Mymensingh, Bangladesh. Blood samples for culture were taken aseptically before starting antibiotic therapy. Microorganisms were isolated and identified by standard microbiological processes and antimicrobial sensitivity patterns were performed against amikacin, gentamicin, ceftriaxone, ciprofloxacin and ceftazidime. The factors which carried a significant risk for development of neonatal sepsis were low birth weight, preterm neonates, meconium stained liquor and prolonged rupture of membrane (>18 hours). Gram negative organisms predominated (68.8%) with Escherichia coli (33.3%) being the commonest. The gram negative bacteria which were isolated sensitive to amikacin, gentamicin and ceftriaxone. The organisms also relatively more sensitive to ciprofloxacin and highly sensitive to ceftazidime. The Gram positive bacteria showed sensitivity against only the antibiotic Ceftriaxone and Ciprofloxacin. The overall mortality was 9%. The outcome of the study will contribute to preventing and treating neonatal sepsis in the hospital.

Abstract
We delineate a KMT2E-related neurodevelopmental disorder on the basis of 38 individuals in 36 families. This study includes 31 distinct heterozygous variants in KMT2E (28 ascertained from Matchmaker Exchange and three previously reported), and four individuals with chromosome 7q22.2-22.23 microdeletions encompassing KMT2E (one previously reported). Almost all variants occurred de novo, and most were truncating. Most affected individuals with protein-truncating variants presented with mild intellectual disability. One-quarter of individuals met criteria for autism. Additional common features include macrocephaly, hypotonia, functional gastrointestinal abnormalities, and a subtle facial gestalt. Epilepsy was present in about one-fifth of individuals with truncating variants and was responsive to treatment with anti-epileptic medications in almost all. More than 70% of the individuals were male, and expressivity was variable by sex; epilepsy was more common in females and autism more common in males. The four individuals with microdeletions encompassing KMT2E generally presented similarly to those with truncating variants, but the degree of developmental delay was greater. The group of four individuals with missense variants in KMT2E presented with the most severe developmental delays. Epilepsy was present in all individuals with missense variants, often manifesting as treatment-resistant infantile epileptic encephalopathy. Microcephaly was also common in this group. Haploinsufficiency versus gain-of-function or dominant-negative effects specific to these missense variants in KMT2E might explain this divergence in phenotype, but requires independent validation. Disruptive variants in KMT2E are an under-recognized cause of neurodevelopmental abnormalities.

Abstract
Diabetes mellitus is one of the leading non-communicable diseases all over the world including Bangladesh. Diabetes is characterized by chronic hyperglycemia and disturbances of carbohydrate, lipid and protein metabolism. Glycated hemoglobin (HbA1c) level of ≥6.5% has been included as a criterion for diagnosis of diabetes. Impaired lipid profile is commonly present in type 2 diabetes. Aim of the study was to investigate the association between serum lipid profile and blood glucose. And hypothesizing that early detection of lipid abnormalities and treatment can minimize the risk for atherogenic cardiovascular disorder and cerebrovascular calamity in patients with type 2 diabetes mellitus (T2DM). This observational cross sectional study was carried out in the department of Biochemistry, Bangladesh Institute of Research & Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) hospital, Dhaka, Bangladesh from January 2016 to June 2016. A total 105 patients with T2DM of age within the range of 30-45 years were selected for the purpose. Fasting blood glucose (FBG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and glycated haemoglobin (HbA1c) levels were evaluated. Test of significance was calculated by unpaired Student's 't' test. Correlation studies (Pearson's correlation) were performed between glycated haemoglobin (HbA1c) and serum lipid profile. Significance was set at p<0.05. Significantly higher mean serum levels of TC, TG and LDL-C and significantly lower mean serum levels of HDL-C were noted in patients with diabetes. Significant correlations were observed between HbA1c value and serum levels of TC, TG and HDL-C (p<0.05) but no significant correlation of HbA1c value with LDL-C in-diabetes patient. The study concluded that HbA1c value correlate well with lipid profile in-diabetes patients. So, HbA1c can be used as a predictor of dyslipidemia in type 2 diabetes.

Abstract
Introduction: Ankle arthrodesis using the Ilizarov technique provides high union rate with the added benefits of early weight-bearing, and the unique advantage of its ability to promote regeneration of soft tissue around the bone, including skin, muscle and neuro-vascular structures, and its versatility to allow correction of the position of the foot by adjusting the frame post-operatively as needed. We describe our experience with this technique and the functional outcomes in our patients. Materials and Methods: This retrospective study was conducted in 20 ankle fusion cases using the Ilizarov method between the years 2007 and 2017. We defined success in treatment by loss of preoperative symptoms and radiological union on plain radiographs of the ankle. Results: Fusion was achieved in all patients (100%). Immediate post-operative ambulation was with full weight bearing (FWB) in 16 (83%) of the participants and non-weight bearing (NWB) in 3 patients (17%). Post-procedure 11 patients (67%) of the participants who were full weight bearing required some form of support for walking for 2-3 weeks. Post-operatively three patients had pin tract infection requiring intravenous antibiotics. Radiological union took range of 6-12 weeks, mean union time was 8 weeks. Only one patient required bone grafting due to bone loss. Average follow-up period was 10-45 months. Conclusion: The Ilizarov technique has a high union rate and leads to general favourable clinical outcome and may be considered for any ankle arthrodesis but is especially useful in complex cases such as for revisions, soft-tissue compromise, infection and in patients with risk for non-union. Early weight bearing is an extra benefit.

Abstract
Reliable posture labels in hospital environments can augment research studies on neural correlates to natural behaviors and clinical applications that monitor patient activity. However, many existing pose estimation frameworks are not calibrated for these unpredictable settings. In this paper, we propose a semi-automated approach for improving upper-body pose estimation in noisy clinical environments, whereby we adapt and build around an existing joint tracking framework to improve its robustness to environmental uncertainties. The proposed framework uses subject-specific convolutional neural network models trained on a subset of a patient's RGB video recording chosen to maximize the feature variance of each joint. Furthermore, by compensating for scene lighting changes and by refining the predicted joint trajectories through a Kalman filter with fitted noise parameters, the extended system yields more consistent and accurate posture annotations when compared with the two state-of-the-art generalized pose tracking algorithms for three hospital patients recorded in two research clinics.

Abstract
Self-medication is widely practiced in both developed and developing countries and an age old practice. Inappropriate self-medication results in increases resistance of pathogens, wastage of resources and serious health hazards. Present study was conducted to determine the pattern of self-medication practices among rural population. This cross-sectional study was carried out at community pharmacies in a rural area of Mymensingh district, Bangladesh from January 2017 to June 2017. Self-medication data were collected from well stocked licensed retail pharmacies and 20 pharmacies were randomly selected as the study site. Considering the prevalence of self-medication practices of 73.6% and relative precision of 10%, the calculated sample size was 138. The data was collected by conducting the interview with participants when they exited from the pharmacy. All data were coded, entered and analyzed using the statistical package for social sciences program version 20 (Chicago IL, USA). Descriptive analysis was employed for statistical evaluation of results. The practice of self medication was more common among age group 30-40 years (31.9%) and most of them were male (60.9%), married (54.3%), farmer (44.9%) and illiterate (42.8%). Family, friends or neighbors were the main source of information for self-medication (65.9%) and common ailments warranting self-medication were headache (52.9%), gastric pain (39.1%), respiratory problem & asthma (34.1%) and fever (30.4%). Multivitamins (76.8%), NSAIDs (65.9%), ranitidine (50.7%), antibiotics (50%), paracetamol (46.4%) and anti-allergic (39.1%) were most commonly used drugs. Over 35% of the participants who treated themselves reported improvement in their condition. Rising prevalence of self-medication is a matter of serious concern. Health education to people regarding responsible self-medication is necessary to prevent misuse and adverse effect of self-medication.

Abstract
Purpose To define the phenotypic and mutational spectrum of epilepsies related to DEPDC5, NPRL2 and NPRL3 genes encoding the GATOR1 complex, a negative regulator of the mTORC1 pathway Methods We analyzed clinical and genetic data of 73 novel probands (familial and sporadic) with epilepsy-related variants in GATOR1-encoding genes and proposed new guidelines for clinical interpretation of GATOR1 variants. Results The GATOR1 seizure phenotype consisted mostly in focal seizures (e.g., hypermotor or frontal lobe seizures in 50%), with a mean age at onset of 4.4 years, often sleep-related and drug-resistant (54%), and associated with focal cortical dysplasia (20%). Infantile spasms were reported in 10% of the probands. Sudden unexpected death in epilepsy (SUDEP) occurred in 10% of the families. Novel classification framework of all 140 epilepsy-related GATOR1 variants (including the variants of this study) revealed that 68% are loss-of-function pathogenic, 14% are likely pathogenic, 15% are variants of uncertain significance and 3% are likely benign. Conclusion Our data emphasize the increasingly important role of GATOR1 genes in the pathogenesis of focal epilepsies (>180 probands to date). The GATOR1 phenotypic spectrum ranges from sporadic early-onset epilepsies with cognitive impairment comorbidities to familial focal epilepsies, and SUDEP.

Abstract
The aging of the Canadian population represents the major risk factor for a projected increase in cancer incidence in the coming decades. However, the evidence base to guide management of older adults with cancer remains extremely limited. It is thus imperative that we develop a national research agenda and establish a national collaborative network to devise joint studies that will help to accelerate the development of high-quality research, education, and clinical care and thus better address the needs of older Canadians with cancer. To begin this process, the inaugural meeting of the Canadian Network on Aging and Cancer was held in Toronto, 27 April 2016. The meeting was attended by 51 invited researchers and clinicians from across Canada, as well as by international leaders in geriatric oncology from the United States and France. The objectives of the meeting were to (1) review the present landscape of education, clinical care, and research in the area of cancer and aging in Canada; (2) identify issues of high research priority in Canada within the field of cancer and aging; (3) identify current barriers to geriatric oncology research in Canada and develop potential solutions; (4) develop a Canadian collaborative multidisciplinary research network between investigators to improve health outcomes for older adults with cancer; (5) learn from successful international efforts to stimulate the geriatric oncology research agenda in Canada. In the present report, we describe the education, clinical care, and research priorities that were identified at the meeting.

Abstract
OBJECTIVE To evaluate factors during acute presumed childhood encephalitis that are associated with development of long-term neurological sequelae. METHODS A total of 217 patients from Rady Children's Hospital San Diego with suspected encephalitis who met criteria for the California Encephalitis Project were identified. A cohort of 99 patients (40 females, 59 males, age 2 months-17 years) without preexisting neurological conditions, including prior seizures or abnormal brain magnetic resonance imaging scans was studied. Mean duration of follow-up was 29 months. Factors that had a relationship with the development of neurological sequelae (defined as developmental delay, learning difficulties, behavioral problems, or focal neurological findings) after acute encephalitis were identified. RESULTS Neurological sequelae at follow-up was associated with younger age (6.56 versus 9.22 years) at presentation (P = 0.04) as well as an initial presenting sign of seizure (P = 0.03). Duration of hospital stay (median of 7 versus 15.5 days; P = 0.02) was associated with neurological sequelae. Of the patients with neurological sequelae, a longer hospital stay was associated with patients of an older age (P = 0.04). Abnormalities on neuroimaging (P = 1.00) or spinal fluid analysis (P = 1.00) were not uniquely associated with neurological sequelae. Children who were readmitted after their acute illness (P = 0.04) were more likely to develop neurological sequelae. There was a strong relationship between the patients who later developed epilepsy and those who developed neurological sequelae (P = 0.02). SIGNIFICANCE Limited data are available on the long-term neurological outcomes of childhood encephalitis. Almost half of our patients were found to have neurological sequelae at follow-up, indicating the importance of earlier therapies to improve neurological outcome.

Abstract
Data from a tuberculosis (TB) prevalence survey conducted in 24 communities in Zambia and the Western Cape, South Africa, January-December 2010, were analysed to determine the influence of smoking, hyperglycaemia and human immunodeficiency virus (HIV) infection on TB symptom reporting in culture-confirmed TB cases. Of 123 790 adults eligible for enrolment, 90 601 (73%) consented and 64 463 had evaluable sputum samples. ORs and 95%CIs were calculated using a robust standard errors logistic regression model adjusting for clustering at community level. HIV-positive TB cases were more likely to report cough, weight loss, night sweats and chest pain than non-HIV-positive TB cases. TB cases who smoked or had hyperglycaemia did not report symptoms differently from cases without these comorbidities.

Abstract
Febrile seizures are the most common type of seizure among children that can be prevented by using prophylactic drugs like Clobazam and Diazepam. The present prospective study was conducted in the Department of Pediatrics, Mymensingh Medical College Hospital and Community Based Medical College Hospital, Bangladesh over a period of 1 year from July 2012 to June 2013 to compare the effectiveness of intermittent Clobazam versus Diazepam therapy in preventing the recurrence of febrile seizures and assessed adverse effects of each drug. A total of 65 patients (32 children administered Clobazam and rest 33 children received Diazepam) of simple and complex febrile seizures aged 6 months to 5 years of both sexes were the study population. Data were collected by interview of the patients, clinical examination and laboratory investigations using the research instrument. Data were analyzed by using Chi-square (χ2) Test, Student's 't' Test and Fisher's Exact Test. For all analytical tests, the level of significance was set at 0.05 and p<0.05 was considered significant. The proportion of patients was higher between age 12-36 months and male was predominant in the both Clobazam and Diazepam groups. Over 31% of patients in Clobazam group who experienced episode of fever within 3 months, 40.6% within 6 months and 9.4% within 9 months compared to 36.4% in Diazepam group within 3 months, 45.5% within 6 months & 12.1% within 9 months after discharge from the hospital. Three (9.4%) patients in Clobazam group and 7(21.3%) in Diazepam group who experienced febrile convulsion during the follow up period. From the data adverse effects within 3 and 6 months experienced by the patient's drowsiness, sedation and ataxia were higher in Diazepam group than those in Clobazam group. However, within 9 months lethargy and irritability were somewhat higher in Clobazam group than those in Diazepam group. The mean duration of hospitalization was significantly higher in Diazepam group compared to Clobazam group (6.0±1.0 vs. 4.6±0.08 days, P<0.001). Seven (21.2%) out of 33 children with febrile seizures in Diazepam group had a history of recurrent seizures, whereas 3(9.4%) of 32 children in the Clobazam group. The risks of recurrent febrile seizure in the Diazepam group was 2.6 times greater compared to those in the Clobazam group (P=0.186). The result indicates that Clobazam is safe, efficacious, requires less frequent dosing and has less adverse effects such as drowsiness, sedation, ataxia and irritability as compared to Diazepam. So, Clobazam may be an alternative to Diazepam given intermittently for prevention of recurrent febrile seizures.

Abstract
We identified a two-branch consanguineous family in which four affected members (three females and one male) presented with constitutive growth delay, severe psychomotor retardation, microcephaly, cerebellar hypoplasia, and second-degree heart block. They also shared distinct facial features and similar appearance of their hands and feet. Childhood-onset insulin-dependent diabetes mellitus developed in one affected child around the age of 9 years. Molecular analysis excluded mutations in potentially related genes such as PTF1A, EIF2AK3, EOMES, and WDR62. This condition appears to be unique of other known conditions, suggesting a unique clinical entity of autosomal recessive mode of inheritance. © 2011 Wiley Periodicals, Inc.

Abstract
Disorders within the “ciliopathy” spectrum include Joubert (JS), Bardet–Biedl syndromes (BBS), and nephronophthisis (NPHP). Although mutations in single ciliopathy genes can lead to these different syndromes between families, there have been no reports of phenotypic discordance within a single family. We report on two consanguineous families with discordant ciliopathies in sibling. In Ciliopathy-672, the older child displayed dialysis-dependent NPHP whereas the younger displayed the pathognomonic molar tooth MRI sign (MTS) of JS. A second branch displayed two additional children with NPHP. In Ciliopathy-1491, the oldest child displayed classical features of BBS whereas the two younger children displayed the MTS. Importantly, the children with BBS and NPHP lacked MTS, whereas children with JS lacked obesity or NPHP, and the child with BBS lacked MTS and NPHP. Features common to all three disorders included intellectual disability, postaxial polydactyly, and visual reduction. The variable phenotypic expressivity in this family suggests that genetic modifiers may determine specific clinical features within the ciliopathy spectrum. © 2011 Wiley Periodicals, Inc.

Abstract
A group of disorders with disparate symptomatology, including congenital cerebellar ataxia, retinal blindness, liver fibrosis, polycystic kidney disease, and polydactyly, have recently been united under a single disease mechanism called 'ciliopathies'. The ciliopathies are due to defects of the cellular antenna known as the primary cilium, a microtubule-based extension of cellular membranes found in nearly all cell types. Key among these ciliopathies is Joubert syndrome, displaying ataxia, oculomotor apraxia, and mental retardation* with a pathognomonic 'molar tooth sign' on brain magnetic resonance imaging. The importance of ciliary function in neuronal development has been appreciated only in the last decade with the classification of Joubert syndrome as a ciliopathy. This, together with the identification of many of the clinical features of ciliopathies in individuals with Joubert syndrome and the localization of Joubert syndrome's causative gene products at or near the primary cilium, have defined a new class of neurological disease. Cilia are involved in diverse cellular processes including protein trafficking, photoreception, embryonic axis patterning, and cell cycle regulation. Ciliary dysfunction can affect a single tissue or manifest as multi-organ involvement. Ciliary defects have been described in retinopathies such as retinitis pigmentosa and Leber congenital amaurosis (defects in photoreceptor ciliary protein complexes), renal syndromes with nephronophthisis and cystic dysplastic kidneys, and liver conditions such as fibrosis and biliary cirrhosis. Recognizing the diverse presentations of the ciliopathies and screening strategies following diagnosis is an important part of the treatment plan of children with cilia-related disorders.

Abstract
OBJECTIVE We sought to create a classification system for pediatric corpus callosal abnormalities (CCA) based upon midline sagittal brain MRI. We used the term CCA for patients with structural variants of the corpus callosum, excluding patients with interhemispheric cyst variant or pure dysplasia without hypoplasia. Currently, no system exists for nonsyndromic forms of CCA, and attempts to create such a system have been hampered by highly variable morphology in patients with sporadic CCA. We reasoned that any useful strategy should classify affected family members within the same type, and that phenotypic variability should be minimized in patients with recessive disease. METHODS We focused recruitment toward multiplex consanguineous families, ascertained 30 patients from 19 consanguineous families, and analyzed clinical features together with brain imaging. RESULTS We identified 3 major CCA classes, including hypoplasia, hypoplasia with dysplasia, and complete agenesis. Affected individuals within a given multiplex family usually displayed the same variant of the class of abnormality and they always displayed the same class of abnormality within each family, or they displayed complete agenesis. The system was validated among a second cohort of 10 sporadic patients with CCA. CONCLUSIONS The data suggest that complete agenesis may be a common end-phenotype, and implicate multiple overlapping pathways in the etiology of CCA.

Abstract
Hereditary spastic paraplegia (HSP) represents a large group of neurological disorders characterized by progressive spasticity of the lower limbs. One subtype of HSP shows an autosomal recessive form of inheritance with thin corpus callosum (ARHSP-TCC), and displays genetic heterogeneity with four known loci. We identified a consanguineous Egyptian family with five affected individuals with ARHSP-TCC. We found linkage to the SPG11 locus and identified a novel homozygous p.Q498X stop codon mutation in exon 7 in the SPG11 gene encoding Spatacsin. Cognitive impairment and polyneuropathy, reported as frequent in SPG11, were not evident. This family supports the importance of SPG11 as a frequent cause for ARHSP-TCC, and expands the clinical SPG11 spectrum.

Abstract
In vitro carrier tests, suspension tests, time-kill curves, and determinations of minimum inhibitory concentrations to evaluate the microbicidal activities of hand antiseptics provide only a preliminary indication of the antimicrobial spectrum and speed of action of a given formulation. Ex vivo testing with human or animal skin at human skin temperature and at contact times reflecting field conditions may give a better indication of a formulation's ability to tackle hand-transmitted pathogens. Field testing of hands for levels of skin microbiota before and after antisepsis may be easier to perform, but it is subject to many uncontrollable factors. Whereas randomised clinical trials may be the ultimate approach to assess the effectiveness of hand hygiene protocols and products in preventing microbial cross-transmission and, ultimately, infections, they can be prohibitively expensive, time-consuming, difficult to design, and therefore impractical. Hence, the primary emphasis should be on in vivo testing on human hands, using a well-designed protocol that closely simulates the recommended field use of the formulation, and possibly followed by clinical studies. The use of these method is the most likely to yield useful data on the potential of a formulation to interrupt the spread of pathogens transmitted by hands in healthcare settings. This review provides a critical assessment of the methods currently used to meet regulatory requirements for hand antiseptics in Europe and North America.

Abstract
Little is known about clinical and epidemiological features of Plesiomonas shigelloides-associated diarrhoea in children. We reviewed hospital-based surveillance records of 38 children with diarrhoea having P. shigelloides as the only pathogen isolated from their faecal specimen. Of those 38 children, 29 (76 per cent) were below 2 years of age and 28 (74 per cent) were male. Thirty-two (84 per cent) children presented with watery diarrhoea and six (16 per cent) had dysenteric stools. Vomiting was a feature in 27 (71 per cent) children and clinically significant dehydration was observed in nine (23 per cent) children. Fever was present in three (8 per cent) children and five (13 per cent) had diarrhoea 14 days. Thirty-three (87 per cent) children were successfully treated with ORS alone and only five (13 per cent) required intravenous fluid in addition to ORS. Plesiomonas shigelloides was isolated throughout the year. The findings may be of public health importance for creating awareness among physicians about the clinical profile and management strategy of P. shigelloides-associated diarrhoea in children.

Abstract
OBJECTIVE To develop non-invasive laboratory variables for the identification of esophageal varices in patients with cirrhosis at Digestive Disease Center, Shifa International Hospital, Islamabad. PATIENTS AND METHODS All patients with chronic viral hepatitis who presented to the Gastroenterology Division between July 2002 to July 2003 were enrolled in the study. All patients with a diagnosis of Chronic Hepatitis who had platelet counts of 140,000, I.N.R of greater than 1.5 and portal vein (PV) diameter of 13 mm or greater were included in the study. All patients underwent endoscopy to see the presence of varices which were graded following the standard criteria RESULTS Of 140 patients, 100 (71%) were males and 40 (29%) females. Esophageal varices were present in 70% of the patients while 30% had no varices. CONCLUSION It was seen that using the standard criteria of a PV diameter 13 mm, I.N.R 1.5 and platelet counts 100,000 for the diagnosis of portal hypertension about 70% patients had endoscopic evidence of esophageal varices. As prophylactic beta blockers are recommended to reduce the chances of a bleed from esophageal varices therefore it is suggested that endoscopy should be done only in patients who fulfill the standard criteria of portal hypertension and those found to have varices should be put on beta blockers.

Abstract
BACKGROUND/AIMS Tropical pancreatitis (TP) refers to a severe type of idiopathic chronic pancreatitis that develops in children in tropical regions of Africa and southern Asia. Phenotypically TP is subdivided into fibrocalculous pancreatic diabetes (FCPD) and tropical calcific pancreatitis without diabetes mellitus (TCP). Recently an association was identified between idiopathic pancreatitis in the USA and Europe and mutations in the serine protease inhibitor, Kazal type 1 (SPINK1) gene (previously termed pancreatic secretory trypsin inhibitor, PSTI). Our aim was to determine if either form of TP has a genetic basis. METHODS We studied 8 well-characterized patients from Bangladesh with FCPD, 4 with TCP and 4 controls without pancreatic disease. The entire SPINK1 gene was sequenced in these patients. RESULTS We detected two disease-associated SPINK1 mutations (N34S/IVS1 - 37T > C and IVS3 + 2T > C) in 6 of 8 patients from Bangladesh with FCPD but not in 4 patients with TCP (p < 0.03) or 4 controls (p < 0.03). CONCLUSIONS We conclude that SPINK1 mutations are associated with FCPD in Bangladesh. Since SPINK1 mutations in Europeans and North Americans are associated with idiopathic chronic pancreatitis that is phenotypically different from FCPD, we further conclude that mutated SPINK1 markedly increases the risk of developing a variety of pancreatic diseases possibly through a chronic elevation of active trypsin within the pancreas.

Abstract
BACKGROUND The cyclical changes in ciliary structure and motion within the human Fallopian tube are well documented. Previous investigators have studied ciliary beat frequency (CBF) in relation to menstrual cycle and anatomical site, but with conflicting results. METHODS Using a technique that records variations in light intensity, we have studied the changes in CBF in relation to the menstrual cycle and anatomical site. Fallopian tubes were collected from 26 women who underwent hysterectomy for benign conditions. Menstrual history, hormone profile and endometrial biopsy results were used to determine the stage of the cycle. Fourteen women were in the proliferative phase, and 12 women in the secretory phase. RESULTS Mean CBF for all subjects was 5.3 plus minus 0.2 Hz. There was no significant difference in CBF in relation to anatomical site. In the fimbrial region the ciliary beat was faster in the secretory (5.8 plus minus 0.3 Hz) as compared with the proliferative phase (4.9 plus minus 0.2 Hz), P < 0.02. CONCLUSIONS It is possible that this increase in fimbrial CBF may contribute to ovum retrieval and transport after ovulation. However, the reproductive significance of the changes in CBF in relation to the menstrual cycle needs further investigation.
