Enteric fever: Diagnostic value of clinical features.

Objectives: to evaluate the diagnostic value of clinical symptoms and signs in enteric fever and to propose a clinical diagnostic criterion. Design: Prospective observational study Setting: Kathmandu Medical College, Teaching Hospital, Kathmandu, Nepal Materials and methods: febrile patients with clinical diagnosis of enteric fever were included in the study with the aim of confirming diagnosis with blood culture, or bone marrow culture and evaluating the diagnostic accuracy of various clinical signs and symptoms. Results: 64% of the clinically diagnosed cases had blood/ bone marrow culture positive. The diagnostic accuracy of the various symptoms and signs excluding fever was between 42%-75.5%. Majority of the symptom and sign did not have very high diagnostic accuracy. Hence a diagnostic criterion was proposed and clinical features with diagnostic accuracy more than 50% were taken into consideration. Major criteria included fever with diagnostic accuracy of 64%, headache with accuracy of 75.5% and relative bradycardia with an accuracy of 66%. Minor criteria included vomiting, diarrhoea, Splenomegaly, chills and abdominal pain /discomfort with diagnostic accuracy of 57%, 55%, 55%, 53% and 51% respectively. Finally after combination of various major and minor criteria a final diagnostic criterion was proposed having an accuracy of 66% and including both major and minor clinical symptom and sign. Conclusion: clinical diagnosis of enteric fever will be very helpful in a country like ours. Though none of the clinical symptoms and sign have very high diagnostic accuracy a diagnostic criteria may be helpful. Criteria including both major and minor signs and symptoms would be the most appropriate diagnostic tool as it includes the important abdominal symptoms and signs of enteric fever. Key words: enteric fever, clinical features, diagnostic criteria.     

Heterogeneities in Consumer Diet Quality and Health Outcomes of Consumers by Store Choice and Income

Obesity and other diet-related health conditions have received much attention in the public health literature over the past two decades. This study investigates the relationship between household food budget shares at different food outlets with diet quality and weight-related health outcomes in the United States. Our analysis used event-level food purchase data from the national household food acquisition and purchases survey (FoodAPS). We find that, after controlling for observables, food purchase location is significantly associated with diet quality and body mass index (BMI). Our findings indicate that larger food budget shares at convenience stores and restaurants are linked with poor diet quality based on the healthy eating index-2015 (HEI-2015) scores and higher BMI. We further explored potential heterogeneity on outcomes of interest across income groups. Results suggest heterogeneous effects may exist across income groups: low-income households, who spent a larger share of their food budget at convenience stores and fast-food restaurants are related to poor diet quality and more likely to be obese. Our findings will help improve understanding of the causes of diet-related health problems and may illuminate potential avenues of intervention to address obesity.     

Two year audit of perinatal mortality at Kathmandu Medical College Teaching Hospital.

Introduction: Perinatal mortality rate is a sensitive indicator of quality of care provided to women in pregnancy, at and after child birth and to the newborns in the first week of life. Regular perinatal audit would help in identifying all the factors that play a role in causing perinatal deaths and thus help in appropriate interventions to reduce avoidable perinatal deaths. Aims and objectives: This study was carried out to determine perinatal mortality rate (PMR) and the factors responsible for perinatal deaths at KMCTH in the two year period from November 2003 to October 2005 (Kartik 2060 B.S. to Ashoj 2062). Methodology: This is a prospective study of all the still births and early neonatal deaths in KMCTH during the two year period from November 2003 to October 2005. Details of each perinatal death were filled in the standard perinatal death audit forms of the Department of Pediatrics, KMCTH. Perinatal deaths were analyzed according to maternal characteristics like maternal age, parity, type of delivery and fetal characteristics like sex, birth weight and gestational age and classify neonatal deaths according to Wigglesworth's classification and comparison made with earlier similar study. Results: Out of the 1517 total births in the two year period, 22 were still births (SB) and 10 were early neonatal deaths (ENND). Out of the 22 SB, two were of < 1 kg in weight and out of 10 ENND, one was of <1 kg. Thus, perinatal mortality rate during the study period was 19.1 and extended perinatal mortality rate was 21.1 per 1000 births. The important causes of perinatal deaths were extreme prematurity, birth asphyxia, congenital anomalies and associated maternal factors like antepartum hemorrhage and most babies were of very low birth weight. According to Wigglesworth's classification, 43.8% of perinatal deaths were in Group I, 12.5% in Group II, 28.1% in Group III, 12.5% in Group IV and 12.5% in Group V. Discussion: The perinatal death audit done in KMCTH for 1 year period from September 2002 to August 2003 showed perinatal mortality rate of 30.7 and extended perinatal mortality rate of 47.9 per 1000 births. There has been a significant reduction in the perinatal mortality rate in the last 2 years at KMCTH. Main reasons for improvement in perinatal mortality rate were improvement in care of both the mothers and the newborns and the number of births have also increased significantly in the last 2 years without appropriate increase in perinatal deaths. Conclusion: Good and regular antenatal care, good care at the time of birth including appropriate and timely intervention and proper care of the sick neonates are important in reducing perinatal deaths. Prevention of preterm births, better care and monitoring during the intranatal period and intensive care of low birth weight babies would help in further reducing perinatal deaths. Key words: Perinatal mortality rate (PMR), still births, early neonatal death (ENND), Total perinatal death (PND).     

Multifocal Childhood Cutaneous Tuberculosis: Report of Two Interesting Cases from Sikkim,India

Abstract: Cutaneous tuberculosis is an important health problem in developing countries such as India. Poverty, overcrowding, malnutrition, and ignorance are predisposing factors. The commonly seen variants of cutaneous tuberculosis are scrofuloderma, lupus vulgaris, and tuberculosis verrucosa cutis. Malnourished children may present with unusual forms of cutaneous tuberculosis. Herein we report two interesting cases of multifocal cutaneous tuberculosis in malnourished children.     

Role of bromocriptine in multi-spectral manifestations of traumatic brain injury

Purpose: Despite the prevalence and cost of traumatic brain injury related disabilities, there is paucity in the literature on modern approaches to pharmacotherapy. Medications may promote recovery by enhancing some neurological functions without impacting others. Herein we discussed the role of bromocriptine in neurorehabilitation for patients with traumatic brain injury. Methods: A cohort comprising of 36 selective nonsurgical cases of traumatic brain injury in minimally conscious state were enrolled in the study. After hemodynamic stability, bromocriptine was given at paediatric dose of 3.75 mg/d and adult dose of 7.5 mg/d. It was administered through a naso-gastric (NG) feeding tube in the patients with minimally conscious state, then changed to oral route after proper swallowing and good gag reflex were ensured in the patient. The drug was slowly reduced over three weeks after neurological improvement in the patients. Positive result was determined by improvd GCS score of 2 and motor power by at least 1 British Medical Council (BMC) motor score. Improvement of deficits was evaluated in terms of fluency of speech for aphasia, task switching, digit span double tasking and trail-making test for cognition and attention, and functional independence measure score for motor functioning and self-independence. Results: Accelerated arousal was seen in 47.0% of cases (8/17) in 4e40 days. In 41.2% of cases (7/17), Glasgow outcome score (GOS) was improved to 4/5 in 90 days. Improvement in hemiparesis by at least 1 BMC score was seen in 55.6% of cases (5/9) in 40 days. Aphasia was improved in 80% of cases (4/5) in 7-30 days. Moderate improvement in cognitive impairment was seen in 66.7% of cases (2/3) in 14e20 days. Improvement in memory was observed in 50% of cases (1/2) in over 30 days. No cases were withdrawn from the study because of adverse reactions of the drug. There was no mortality in the study group. Conclusion: Bromocriptine improves neurological sequelae of traumatic brain injury as well as the overall outcome in the patients. If medication is given to promote recovery and treat its associated disabilities, clinicians should thoroughly outline the goals and closely monitor adverse effects.     

Use of bone marrow derived stem cells in a fracture non-union

This is an attempt of using in vitro cultured mesenchymal stem cells (MSCs) from bone marrow in joining of a fracture non-union. Bone marrow cells were obtained and differentially centrifuged for MSCs that were grown in vitro in mesenchymal stem cell basal medium aseptically, for 10 d. The cell mass was injected around the fracture non-union. Healthy conditions of development of tissue regeneration at the trauma site and due bone joining were recorded. It is concluded that in vitro cultured MSCs had a blithesome effect on the fracture non-union.
