Sputum Inflammatory Cells and their Impact on Asthma Control in Adults: A Prospective Study

Background: Asthma is broadly categorized as eosinophilic or noneosinophilic. Noneosinophilic asthma (NEA) can be paucigranulocytic asthma (PGA), mixed granulocytic asthma (MGA), or neutrophilic asthma (NeuA). A relationship between the cytological type of inflammation and response to treatment with inhaled corticosteroids (ICS) in asthma has been of great interest. The objective of the current study was to predict the control of asthma according to sputum inflammatory cells. Materials and methods: A total of 58 patients were evaluated. Sputum was induced and sent for cytological examination. Patients were prescribed controller and reliever medications as per the GINA guidelines. Accordingly, subjects were divided into eosinophilic, neutrophilic, mixed granulocytic, and paucigranulocytic asthma. The response to treatment was classified as poorly controlled based on ACT score. Results: Out of 58 patients, eosinophilic asthma (EA) was 24% and noneosinophilic 76% (NeuA 17%, MGA 23%, and PGA 36%). After treatment, 14 (24.13%) patients were found poorly controlled. Poor control was in 5.17% among EA and 18.97% in NEA phenotypes. Poor control was significantly higher in females, NeuA, and MGA. Peripheral eosinophilia affects control of asthma adversely. Conclusion: Pretreatment sputum analysis can predict the asthma control and steroid responsiveness. Mixed granulocytic asthma and NeuA are difficult to control, and PGA is the best responder.

Is there an association between vitamin D and risk of stroke?: a North Indian study

Background: Vitamin D deficiency is present in India in epidemic proportions despite plenty of sunshine. Reduced plasma 25(OH) D concentrations as a diagnostic marker of vitamin D deficiency have been in past decade associated with several well-established risk factors for ischaemic stroke, such as arterial hypertension, thrombosis, atherosclerosis. The aims and objectives of this study was to compare the serum 25(OH) D levels between the first ever acute stroke patients and healthy controls.Methods: A cross-sectional, case control study was conducted in a tertiary care hospital in New Delhi situated in north India. Serum 25‑hydroxyvitamin D (25(OH) D) levels in 85 patients of ischemic stroke, presenting within 7 days of onset of stroke was measured and was compared with 70 age and gender matched controls.Results: The mean age was 61.02±11.58 years and 58.63±11.28 years in cases and controls respectively. Females constituted 37.6% of the total number of cases and 43.4% of the controls. The age and gender-distribution were comparable between the cases and controls. The median value (IQR) of serum 25(OH) vitamin D level was 7.94 ng/mL (4.59-14.00) in the cases and it was 8.82 ng/mL (5.59-14.70) in the controls. The difference between the serum 25(OH) vitamin D levels of the two groups was not found to be statistically significant.Conclusions: There is a high prevalence of biochemical hypo-vitaminosis D in apparently healthy Indians of all age and sex groups despite adequate sunshine. There is no association between low vitamin D levels and stroke.

Plasma ghrelin levels after laparoscopic sleeve gastrectomy in obese individuals

Background & objectives: Ghrelin is an orexigenic gut hormone expressed by the gastric fundus. Laparoscopic sleeve gastrectomy (LSG) procedure involves resection of the gastric fundus leading to a decreased appetite and weight loss. This study was undertaken to determine the levels of plasma ghrelin after sleeve gastrectomy in obese patients. Methods: The study was conducted on 90 morbidly obese patients [body mass index (BMI) >40 kg/m[2]] and severely obese patients (BMI >35/kg/m[2]) who underwent sleeve gastrectomy. The patients were followed up for six months. Weight loss parameters and plasma ghrelin levels were assessed pre- and postoperatively. Results: A significant weight loss and decrease in BMI were observed at three and six months postoperatively. A significant decrease in plasma ghrelin levels over six months of follow up postoperatively was also seen. Interpretation & conclusions: These preliminary findings indicated inhibition of ghrelin production after LSG leading to a decrease in the plasma ghrelin levels within a few days of surgery and sustainable weight loss in obese patients.

A study on community associated Staphylococcus aureus and its susceptibility pattern to Mupirocin and Fusidic acid in primary pyoderma patients

Background: Primary pyodermas are one of the most common dermatological diseases. Staphylococcus aureus (S. aureus) is frequently isolated. It has developed resistance to many antimicrobials and Methicillin Resistant Staphylococcus aureus (MRSA) is a major problem. The precipitous usage of topical antimicrobials especially Mupirocin and Fusidic acid has increased the development of multi-resistant strains of S. aureus and in India, few studies have shown susceptibility profile to these drugs. Aim: This study aimed at the clinical and bacteriological profile in primary pyoderma patients, prevalence of MRSA and the resistance pattern of S. aureus to Mupirocin and Fusidic acid. Materials and methods: Patients with primary pyodermas from community were recruited. Gram stain and culture sensitivity was done with swabs taken from the lesions. Antibiotic susceptibility for Sethi P, Betkerur J, Sethi P, Adhlakha B, Kulkarni M, Murthy KC. A study on community associated Staphylococcus aureus and its susceptibility pattern to Mupirocin and Fusidic acid in primary pyoderma patients. IAIM, 2016; 3(11): 27-35. Page 28 S. aureus was tested using VITEK- 2. Mupirocin and Fusidic acid susceptibility was determined by Estrip method. Observations: A total of 107 patients of primary pyodermas were included. Pyoderma were common in young age group (P = 0.001). Poor hygiene was the main predisposing factor. Furunculosis (45.8%) was the most common pyoderma followed by impetigo and folliculitis (16.8% each). Culture was positive in all except 3. S. aureus was isolated in 61.7% and polymicrobial flora in 13.1%. Prevalence of MRSA was 39.5% (P= 0.066). All strains of S. aureus demonstrated 100% susceptibility to Mupirocin and Fusidic acid. Conclusions: Furunculosis still has the highest incidence in adult population with a high prevalence of MRSA (39.5%). Despite extensive usage of Mupirocin and Fusidic acid, no resistance was found in this part of India.

Use of John Cunningham virus polymerase chain reaction in the diagnosis of progressive multifocal leucoencephalopathy - A rare presenting manifestation in an HIV-positive patient.

John Cunningham virus infection is an important cause of progressive multifocal leucoencephalopathy (PML) in the context of advanced human immunodeficiency virus infection. Limited data are available regarding the true incidence of PML as a presenting manifestation of HIV. We report one such case and also highlight the effective use of polymerase chain reaction in confirming its diagnosis.

Congenital CMV infection; diagnosis in symptomatic infants.

Background: Samples from babies exhibiting clinical symptoms suggestive of congenital infection are referred regularly to NICD, New Delhi,, from Government Hospitals located in Delhi and a home for abandoned children (Palna), for the diagnosis of etiological agents like toxoplasma, rubella, CMV and herpes. Blood samples of mothers of most of the affected babies are also received. Objective: Evaluation of rapid and accurate technique for the diagnosis of congenital CMV infection. Materials and Methods: One hundred and twenty five blood samples suggestive of symptomatic congenital CMV infection were selected from samples received at NICD during the period June 2005-March 2007. A request to collect and send the urine samples of the selected babies was sent to the respective hospitals. Serum samples of the babies were tested for CMV-IgM antibodies using µ-capture ELISA. Mothers' serum samples were subjected to CMV-IgM and IgG class antibodies assay by commercial ELISA kits. DNA isolation and amplification was performed in urine samples and some of the serum samples using a commercial PCR kit for detection of HCMV. Blood and urine samples from 20 normal babies were included in the study. Results: Twenty Seven serum samples (21.6%) of infants, of the 125 tested, were positive for CMV-IgM antibodies. Twenty five samples (20%) showed amplification of CMV -DNA. All 25 samples positive for PCR were positive for CMV IgM antibodies. Sera of 73 mothers, out of 75 tested (97.3%), were positive for CMV IgG antibodies. However, none of them was positive for CMV IgM antibodies. Mothers of all 27 positive babies were positive for CMV-IgG antibodies. Serum and urine samples from 20 normal babies were negative for ELISA and PCR. Conclusion: µ-capture ELISA technique was found to be more sensitive than PCR (92.6%) for detection of congenital CMV infection. ELISA is also rapid, less cumbersome and cost effective for diagnosis of CMV infection.

Zolpidem at supratherapeutic doses can cause drug abuse, dependence and withdrawal seizure.

Zolpidem is a non-benzodiazepine hypnotic drug, acts selectively through omega 1 receptors of GABAA. It is thought to be safer than benzodiazepines but we report a case of zolpidem drug abuse, dependence and withdrawal seizure.

Megalencephalic leukoencephalopathy with subcortical cysts.

Megalencephalic leukocncephalopathy is rare disorder seen in India in patient belonging to Agarwal community. Many of the patients may have a mild clinical course with gradual worsening of neurological disability. A case is being reported who was followed for 17 years and paradoxically showed radiological and clinical improvement.

Brainstem death: implications in India.

Brainstem death and brain death although practically same with regards to the concept of organ donation, remain technically different. Brain death mandates irreversible cessation of all the functions of the entire brain and brainstem while brainstem death signifies irreversible damage to the brainstem. As per the Indian law, brainstem death is the legal requirement and not brain death.

Oral exfoliative cytology of smokers at discrete clinical stages using AgNOR staining.

OBJECTIVE: This study was designed to evaluate oral exfoliative cytology of smokers without any clinically evident lesion and smokers with leukoplakia or oral cancer using AgNOR staining. STUDY DESIGN: Cytological smears of 30 smokers without lesion, 30 smokers with leukoplakia, 30 smokers with oral cancer and 30 non-smokers (control group) were studied using one step silver staining method. The AgNOR count was established on 100 cells. Mean AgNOR count and mean % of cells with 5 or more AgNORs was evaluated. The count values of groups were compared and analysed using Student's unpaired t-test. RESULTS: The mean AgNOR count for control group was 2.94 +/- 0.325, smokers without lesion 3.79 +/- 0.480 smokers with leukoplakia 3.89 +/- 0.433 and oral cancer 4.96 +/- 0.467. Mean % of cells with 5 or more AgNORs was 11.7, 26.5, 30.2 and 55.8 for control group, smokers without lesion, smokers with leukoplakia and oral cancer respectively. CONCLUSION: Analysis of AgNORs suggest that smoking influences proliferative activity in cells of smokers without any clinical lesion and that oral cancer shows highest proliferative activity.

Dilated pore of Winer.

Two cases of dilated pore of Winer were observed. First case had single defined black papule with well defined margin, central pore and discharge of black powdery material from nose since 3 years. The second case had one 9 mm, black well-defined papule with central pore discharging black powdery material on right forearm since 9 months and 9 similar smaller papules were seen on forearm and lower abdomen. Histopathologically both revealed greatly dilated infundibulum lined by acanthotic epidermis and atrophic subinfundibular hair structures thus confirming diagnosis of dilated pore of Winer.

Cellular blue naevus.

A 31-year-old man had asymptomatic, stationary, 1.5X2 cm, shiny, smooth, dark blue nodule on dorsum of right hand since 12-14 years. In addition he had developed extensive eruption of yellow to orange papulonodular lesions on extensors of limbs and buttocks since one and half months. Investigations confirmed that yellow papules were xanthomatosis and he had associated diabetes mellitus and hyperlipidaemia. Biopsy of blue nodule confirmed the clinical diagnosis of cellular blue naevus. Cellular blue naevus is rare and its association with xanthomatosis and diabetes mellitus were interesting features of above patients which is being reported for its rarity.

Relationship of Xba1 and EcoR1 polymorphisms of apolipoprotein-B gene to dyslipidemia and obesity in Asian Indians in North India.

BACKGROUND: Genetic investigation of dyslipidemia and obesity prevalent in the Indian population form the basis of this study. METHODS AND RESULTS: The frequency of restriction fragment length polymorphisms (Xba1 and EcoR1) of the apolipoprotein-B gene was investigated in a case-control study of 30 hyperlipidemic and 40 normolipidemic subjects. By univariate analysis, old age, higher body mass index, waist-hip ratio and sum of four skinfolds were found to be significantly associated with hyperlipidemia. The frequencies of X- and E+ alleles of the apolipoprotein-B gene were significantly higher in North Indians in the state of New Delhi (0.83 and 0.91, respectively) as compared to the observations made in Caucasians in previous studies, but was similar to the frequency reported in Indians settled in Singapore and the UK. There were no significant differences in the allele or genotype frequencies of either Xba1 or EcoR1 polymorphisms between the hyperlipidemic and normolipidemic groups. On multiple logistic regression analysis considering body mass index, waist-hip ratio, percentage body fat and genotypes as independent variables, no association was observed between the apolipoprotein-B genotypes and serum lipid components. Further, there were no associations between apolipoprotein-B polymorphisms and generalized obesity (as assessed by body mass index, sum of four skinfolds, and percentage total body fat) and abdominal obesity (as measured by waist circumference and waist-hip ratio). CONCLUSIONS: We conclude that apolipoprotein-B (Xba1 and EcoR1) polymorphisms do not appear to influence serum lipid levels and parameters of generalized andregional obesity in the study sample.

Primary antiphospholipid syndrome in stroke in the young.

Antiphospholipid syndrome is an uncommon cause of stroke. A 12 year old girl with this syndrome is reported who presented with thrombotic stroke and high titres of anticardiolipin (aCL) and lupus anticoagulant (LAC). The patient improved subsequently and was put on aspirin. The present report highlights the importance of screening for aCL and LAC in cases of stroke in young patients.
