In children with drug-resistant epilepsy, the rate of freedom from seizures at 1 year was higher with epilepsy surgery than with medical therapy alone. Most measures of cognitive development were better in the surgery group than in the medical-therapy group.

Context.--The histologic features in patients with acute-on-chronic liver failure (ACLF) are evolving, and histologic indicators of patients' poor prognosis are not yet fully established. Objective.--To evaluate the independent histologic predictors of 28-day mortality in ACLF patients on core-needle liver biopsies. Design.--Core-needle biopsies from patients with a diagnosis of ACLF (n = 152) as per the European Association for the Study of the Liver criteria were included during 8 years. Liver biopsies from 98 patients with compensated chronic liver disease were included as disease controls for histologic comparison. Features of ongoing changes, such as hepatic necrosis, hepatic apoptosis, cholestasis, hepatocyte degeneration, bile ductular proliferation, Mallory-Denk bodies, steatosis, and extent of liver fibrosis, were analyzed for predicting short-term mortality (28 days). A P value of <.05 was considered significant. Results.--In our cohort of ACLF patients, the following etiologies for acute decompensation were identified: alcohol, 47 of 152 (30.9%); sepsis, 24 of 152 (15.7%); hepatotropic viruses, 20 of 152 (13.1%); drug-induced liver injury, 11 of 152 (7.2%); autoimmune flare, 9 of 152 (5.9%); mixed etiologies, 5 of 152 (3.2%); and cryptogenic, 36 of 152 (23.6%). On histologic examination, hepatic necrosis (P <.001), dense lobular inflammation (P =.03), cholestasis (P <.001), ductular reaction (P =.001), hepatocyte degeneration (P <.001), and absence of advanced fibrosis stages (P <.001) were identified significantly more othen in ACLF patients than in disease controls on univariate analysis. On multivariate Cox regression analysis, the absence of advanced Ishak histologic activity index fibrosis stages (P =.02) and the presence of dense lobular inflammation (P =.04) were associated with increased 28-day mortality in ACLF patients. After adjusting the clinical causes of acute decompensation, only dense lobular inflammation was found as an independent predictor of short-term mortality (P =.04) in ACLF patients. Conclusions.--Dense lobular necroinflammatory activity is a clinically independent histologic predictor of 28-day short-term mortality in patients with ACLF.

Background Patients with asymptomatic prenatally diagnosed hydronephrosis may progress to needing surgery; no biomarker supporting the identification of these cases is currently available. The aim of the study was to assess the role of Plasma Renin Activity (PRA) as a discriminatory factor to identify patients with asymptomatic prenatally diagnosed hydronephrosis who require close monitoring and are at-risk for surgery. Methods The study group consists of 30 children prenatally diagnosed with asymptomatic unilateral hydronephrosis, initially managed with medical follow-up. Pyeloplasty was indicated if patients became symptomatic or if there was a significant drop in split renal function (SRF) during follow-up. An association was sought between PRA and renal parameters in post-hoc analysis. Results During the mean follow-up of 55.5 ± 8.2 months, 13/30 (43.3%) patients developed delayed drainage and 8/30 (26.6%) underwent pyeloplasty. Mean PRA was higher at presentation in the group which later presented with a drop in differential kidney function  ≥ 10%, while it was within the normal range for age in the other patients. Before pyeloplasty, progression to delayed drainage coincided with a drop in SRF and a rise in PRA. While PRA levels normalized after pyeloplasty, SRF improved but did not reach initial values. A mean rise of 68.9% in PRA preceded current indications for surgery by 27.5 ± 9.5 months. Conclusions A progressive increase in PRA in children with asymptomatic prenatally diagnosed hydronephrosis reflects obstructive stress in the tubulo-interstitial compartment. This stress is relieved by pyeloplasty and is reflected by a drop in PRA after surgery. PRA can, thus, serve as the discriminatory factor to identify hydronephrosis patients ‘at-risk’ for surgery even before the current criteria for pyeloplasty are met.

Aim: The objective of this study was to develop and validate a knowledge, attitude, and practice (KAP) questionnaire about obesity among obese individuals. Materials and Methods: The questionnaire was developed following a standardized protocol that consisted of literature review, focused group discussions, and expert opinion. A cross-sectional survey on 100 obese individuals was carried out to validate the tool. Exploratory factor analysis was performed, using principal component with varimax rotation, to establish the construct validity of the questionnaire. Internal consistency of the questionnaire was tested using Cronbach's α coefficient. Results: KAP questionnaire with 42 items categorized under three domains knowledge, attitude, and practices was developed. The KAP sections have 14, 15, and 13 items, respectively. Independent Cronbach's α for KAP domains were 0.75, 0.75, and 0.63, respectively, indicating good internal consistency. Conclusion: The developed questionnaire will be helpful in achieving better understanding of the patients' KAP about obesity. It has satisfactory validity and good internal consistency.

Purpose: Drawing differential diagnoses to a Neuro-ophthalmology clinical scenario is a difficult task for a neurology trainee. The authors conducted a study to determine if a mobile application specialized in suggesting differential diagnoses from clinical scenarios can complement clinical reasoning of a neurologist in training. Methods: A cross-sectional multicenter study was conducted to compare the accuracy of neurology residents versus a mobile medical app (Neurology Dx) in drawing a comprehensive list of differential diagnoses from Neuro-ophthalmology clinical vignettes. The differentials generated by residents and the App were compared with the Gold standard differential diagnoses adjudicated by experts. The prespecified primary outcome was the proportion of correctly identified high likely gold standard differential diagnosis by residents and App. Results: Neurology residents (n = 100) attempted 1500 Neuro-ophthalmology clinical vignettes. Frequency of correctly identified high likely differential diagnosis by residents was 19.42% versus 53.71% by the App (P < 0.0001). The first listed differential diagnosis by the residents matched with that of the first differential diagnosis adjudicated by experts (gold standard differential diagnosis) with a frequency of 26.5% versus 28.3% by the App, whereas the combined output of residents and App scored a frequency of 41.2% in identifying the first gold standard differential correctly. The residents correctly identified the first three and first five gold standard differential diagnosis with a frequency of 17.83% and 19.2%, respectively, as against 22.26% and 30.39% (P < 0.0001) by the App. Conclusion: A ruled based app in Neuro-ophthalmology has the potential to complement a neurology resident in drawing a comprehensive list of differential diagnoses.

Background: With demographic shifts, there is an unprecedented increase in noncommunicable diseases, multimorbidity, and geriatric syndromes among older adults, especially in economically weaker sectors. However, there is no socioculturally appropriate tool to screen older adults for age-related health needs, multimorbidity, and geriatric syndromes at their doorstep. Objective: Our objective was to create a self-assessment tool, \"integrated care tool\" (ICT), and to assess its psychometric properties by applying it on older adults from multiple settings such as hospital, community, and old-age home (assisted living services). Methods: new questionnaire was developed using standardized procedure including item development, pilot testing, and psychometric validation. After obtaining the institutional ethics committee clearance, data were collected from consenting respondents attending the Outpatient Department of Geriatric Medicine, All India Institute of Medical Sciences, New Delhi, community settings through health camps, and long-term care center, between May 2016 and February 2017. Data were computerized and analyzed by principal component analysis as extraction method and orthogonal varimax as rotation method. Results: The final 30-item questionnaire was arranged into various domains as per rotated component matrix analysis. Overall internal consistency of the final questionnaire, as calculated by Cronbach's alpha, was 0.79, and the measure of sampling adequacy was 0.79. Conclusion: ICT-BRIEF is a simple, self-assessment/caregiver-assisted tool to screen the health needs of older adults. This tool can be validated for developing risk score and scaled up to generate a large database to create elderly centered care plans.

Purpose: The purpose of this study is to determine the antimicrobial susceptibility pattern, serotype distribution and sequence type (ST) of Streptococcus pneumoniae isolates from invasive and non-invasive infection and correlate it with isolates from commensal nasopharyngeal flora to ascertain their role in infection. Materials and Methods:S. pneumoniae isolates from blood, cerebrospinal fluid, pleural fluid and respiratory secretions (sputum, bronchoalveolar lavage and nasopharyngeal swab/throat swab) were analysed to determine ST, serotype and antimicrobial susceptibility pattern. Serotyping was performed by multiplex polymerase chain reactions as well as by quellung reaction. Antimicrobial susceptibility testing was determined using Kirby Bauer’s disc diffusion method as per the Clinical Laboratory Standards Institute guidelines. Minimum inhibitory concentration was determined using E-test for penicillin. Multilocus sequence typing (MLST) was done to understand genetic relatedness and evolutionary relationship among strains. Results: A total of 125 S. pneumoniae isolates were collected, including 25 from invasive pneumococcal disease, 25 from non-invasive and 75 from nasopharyngeal swab of healthy children (Commensal). Resistance to penicillin, erythromycin, and co-trimoxazole was observed in 14.4%, 12% and 81.6% of the isolates, respectively, by KirbyBauer’s disc diffusion method. Serotype 14 was found to be the most prevalent in invasive and non-invasive isolates, while serotype 6 was the most common in commensal isolates. New STs were found among invasive (ST13826, ST13827), non-invasive (ST13823, ST13824, and ST13961) and commensal (ST13825) isolates. Conclusion: MLST sequence analysis shows that invasive isolates were found to be clustered with non-invasive and commensal isolates. Analysis of MLST suggests the possibility of genetic relatedness and exchange of genetic material between invasive, non-invasive and commensal isolates.

Background Oral cancer is the most common cancer among Indian men, and has strong tendency of metastatic spread to neck lymph node which strongly influences prognosis especially 5 year survival-rate and also guides the related managements more effectively. Therefore, a reliable and accurate means of preoperative evaluation of extent of nodal involvement becomes crucial. However, earlier researchers have preferred to address mainly its dichotomous form (involved/not-involved) instead of ordinal form while dealing with epidemiology of nodal involvement. As a matter of fact, consideration of ordinal form appropriately may increase not only the efficiency of the developed model but also accuracy in the results and related implications. Hence, to develop a model describing factors associated with ordinal form of nodal involvement was major focus of this study. Methods The data for model building were taken from the Department of Surgical Oncology, Dr.BRA-IRCH, AIIMS, New Delhi, India. All the OSCC patients (duly operated including neck dissection) and confirmed histopathologically from 1995 to 2013 were included. Further, another data of 204 patients collected prospectively from 2014 to 2015 was considered for the validation of the developed model. To assess the factors associated with extent of nodal involvement, as a first attempt in the field of OSCC, stepwise multivariable regression procedure was used and results are presented as odds-ratio and corresponding 95% confidence interval (CI). For appropriate accounting of ordinal form, the ordinal models were assessed and compared. Also, performance of the developed model was validated on a prospectively collected another data. Results Under multivariable proportional odds model, pain at the time of presentation, sub mucous fibrosis, palpable neck node, oral site and degree of differentiation were found to be significantly associated factors with extent of nodal involvement. In addition, tumor size also emerged to be significant under partial-proportional odds model. Conclusions The analytical results under the present study reveal that in case of ordinal form of the outcome, appropriate ordinal regression may be a preferred choice. Present data suggest that, pain, sub mucous fibrosis, palpable neck node, oral site, degree of differentiation and tumor size are the most probable associated factors with extent of nodal involvement.

Bacterial vaginosis (BV) is diagnosed by the microbiological Nugent scoring method or clinical Amsel’s criteria. Assessment of 404 vaginal samples (293 women) identified 110 (27.2%), 108 (26.7%) and 161 (39.9%) samples to be BV-positive using Nugent’s method, standard Amsel’s criteria and simplified Amsel’s criteria respectively. The sensitivity, specificity, and kappa statistic (κ) for standard and simplified Amsel’s criteria were 71.8% (95% CI = 62.4–80.0), 90.1% (95% CI = 62.4–86.1), 0.62 (95% CI = 0.53–0.72) and 88.2% (95% CI = 80.6–93.6), 78.2% (95% CI = 73.1–82.8), 0.58 (95% CI = 0.49–0.67), respectively. A combination of vaginal pH and clue cells exhibited the highest concordance (κ = 0.64, 95% CI = 0.54–0.74) with Nugent’s method and may be used for simplified BV diagnosis.

Background: Pain is still a common feature in all types of cancers including head and neck and thoracic cancer. Neuromodulatory techniques have gained popularity over opioids in recent times because of the risks associated with chronic opioid therapy. There are no clinical trials evaluating the efficacy of scrambler therapy (ST) for the management of pain due to head and neck and thoracic cancer. Objective: This trial was undertaken to evaluate the efficacy of scrambler therapy (ST) for pain relief and to assess the possible effect of ST on the dosage of opioids in patients suffering from cancer pain. Study design: A randomized control trial (RCT) was performed. Setting: The trial was conducted at the Pain and Palliative Care Unit of the Dr. B.R. Ambedkar Institute Rotary Cancer Hospital of All India Institute of Medical Sciences, New Delhi, India. Method: Forty patients were included in each of the 2 arms, control and Intervention. In both arms, patients were given pain management drugs. In the intervention group, patients additionally received 10 consecutive sessions of ST with one follow-up after 7 days. A numeric rating scale (NRS-11) was used to measure pain. Drug dosage was also recorded. Results: Overall, pain decreased in both arms. However, pain decreased more in the intervention arm as compared to the control arm. The total change in the mean score of the NRS-11 from baseline to follow-up was 3.1 and 6.19 in the control and ST arms, respectively. Differences between pain scores in both arms became significant from day 3 onwards. Mean morphine dose was significantly lower in the intervention arm from day 7 onwards. Limitations: The study followed the patients until one week after the last treatment session and encouraged patients to return for treatment if their pain returned to previous levels within 10 days. Moreover, patients in the control arm received the standard of care in the form of pharmacological treatment but did not receive either transcutaneous electrical nerve stimulation (TENS) or a sham (placebo) procedure. Conclusions: The trial showed that ST is an effective treatment for the management of pain due to head and neck and thoracic cancer. On the basis of this study, the use of ST for the management of refractory cancer pain in head and neck and thoracic cancer is recommended.
