RESUMEN
Introduction: Asthma and chronic obstructive pulmonary disease (COPD) are characterized by chronic airway inflammation. Lack of knowledge about the correct inhalation techniques leads to poor control of both diseases. This study aimed to study the effectiveness of inhalation technique training in patients with COPD and asthma. Materials and methods: A total of 132 patients fulfilling the inclusion criteria were trained with the correct technique of inhalation on day 0 and at the end of 1 and 6 months. Evaluation of technique training was done on these three occasions posttraining. The mean score of devices was obtained, and the mean inhalation technique score of various devices was compared. Results: Out of 132 patients, 65.1% (86/132) patients were using a dry powdered inhaler (DPIs), 26.5% (35/132) patients used metered dose inhalers (MDIs), and 8.4% (11/132) patients used MDI with spacer. The mean scores of patients using MDI at baseline were 5.68 ± 0.83, and after 1 month, 6.68 ± 0.58 (p < 0.000). The inhalation technique mean score of MDI improved after 6 months, 7.02 ± 0.56 as compared to baseline (p < 0.008) mean score of the patients using DPIs improved after 1 month, 5.53 ± 0.58 as compared to baseline 4.37 ± 5.53 (p < 0.000). There was no statistical improvement in the device mean score of DPIs after 6 months, 5.62 ± 0.55 when compared with 1 month, 5.53 ± 0.58 (p < 0.117). Patients who used pressurized metered-dose inhalers (pMDI) with spacers improved their inhalation score after 1 month by 6.90 ± 0.94 as compared to the baseline score of 6.90 ± 0.94 (p < 0.001). The mean score decreased marginally after 6 months, 7.818 ± 0.60, as compared to the score at the end of 1 month of 8.27 ± 0.64 (p < 0.053). Discussion: Patients showed improvement in the technique of inhalation after educational training, reinstructions, and a standard checklist.
RESUMEN
Climate change is posing a great threat to agriculture and food security, especially in the agriculture oriented and developing countries like India. The present study was carried out to critically study the impact of climate change on productivity of major cereal and commercial crops by statistically analyzing the time series data. The analysis inferred that crop production of both food and commercial crops in India has increased since 1960-61. It was observed that major food crops (rice & wheat) were adversely affected by increase in maximum temperature and decrease in rainfall. The alternative measures such as area under cultivation, irrigation, fertilizer and pesticide consumption were observed to be nullifying that negative impact of climate change by enhancing the overall production. However, the commercial crops were observed to be positively affected by the increasing temperature. The study suggested that although the agriculture sector is able to withstand the adverse impact of climate change till now, but in near future this situation can become reversed. This necessitates the implementation of appropriate adaptation and mitigation measures to deal with the problems of climate change and to ensure the food security and food safety along in long run.
RESUMEN
Background: Isolation of free‑living amoebae (FLA) is reported sparsely from water taps, ventilators, air conditioners, haemodialysis units and dental irrigation systems of hospitals worldwide. Their prevalence in hospital environment especially in wards having immunocompromised patients may pose a risk to this group of susceptible population as they may cause disease themselves or may carry pathogens inside them. No study from India has performed such surveillance. Objective: To evaluate extent of FLA contamination in water sources of bone marrow transplant (BMT) intensive care unit (ICU), transplant ICU, haemodialysis unit and high dependency unit in a tertiary care hospital in India. Materials and Methods: A total of hundred samples including fifty each of tap water samples and swabs from mouth of taps used for drinking, bathing and hand washing purposes in these units were collected according to standard procedure. Samples were inoculated onto non‑nutrient agar plates at room temperature followed by morphological confirmation. Molecular identification including polymerase chain reaction (PCR) and sequencing was performed in culture positive samples. Results: Four tap water samples and ten swab samples showed growth of trophozoites and cyst formation. Morphologically, four amoebae resembled Acanthamoeba spp. which was further confirmed by PCR and sequencing showed them to be of T3 and T4 genotypes. Conclusion: The presence of these FLA in hospital water sources emphasises the urgent need of implementing effective preventive measures. Further studies are required to estimate the true prevalence of FLA in Indian hospitals by taking larger number of samples.
RESUMEN
There are only a few case reports in the literature on the coexistence of aspergillosis and echinococcosis. We report a case of a 45-year-old immunocompetent patient who presented with a history of intermittent fever and cough with haemoptysis. Chest x-ray and CECT showed a large cystic lesion in right lower lobe with multiple floating membranes. Histopathological examination of cyst wall revealed the laminated membrane of hydatid cyst along with infiltration of its wall with septate fungal hyphae with acute angle branching suggestive of aspergillosis.
RESUMEN
A rapid increase in unnatural deaths in females, especially in the first few years of their married life was observed in our society for last few decades. This drew the attention of people and forced the socio-political system to investigate and develop preventive measures [1-3]. In this study most of the victims were young (18-22 years) Hindu females of middle or lower-middle socioeconomic status living in a joint family with their husband & in- laws and died in suspicious circumstances within three years of their marriage. Majority of such deaths were suicidal or homicidal. Burning was the most common cause of death, followed by hanging and poisoning. Few of them were strangled to death and then burned to temper the evidences. Pressure for dowry was the single largest reason behind such deaths. Ill-treatment by the in-laws, rash and negligent behavior or extra-marital affairs of husbands, and mal-adjustment in females were other important reasons. Few of these deaths were also accidental, catching fire while cooking or handling open lamp/fire carelessly. Loose synthetic saris of the victims were responsible for large number of mortalities in this study.

BACKGROUND: Internal malignancies are accompanied by various skin changes which may be specific infiltrates or non-specific changes. This study is aimed at determining the frequency of such changes in malignant disease treatment center attendees in India. METHODS: A study of 300 confirmed cases of internal malignancy at a malignant disease treatment center was undertaken to evaluate these skin changes. Specific infiltrates were confirmed by histopathology. Statistical methods were employed to calculate significance in non-specific lesions by comparing with 300 controls not suffering from internal malignancy. RESULTS: Skin changes were present in 82 (27.3%). Cutaneous metastases were found in 19 (6.3%); non-contiguous in 5 (1.6%); contiguous in 14 (4.3%). Non-specific skin lesions numbered 74 (11.6%) in 52 patients. Statistically significant non-specific skin changes were acquired ichthyosis, herpes zoster and generalized pruritus. CONCLUSION: Metastases usually occurred late in internal malignancy (17, 5.6%) except in a case each of histiocytic lymphoma and non-Hodgkin's lymphoma (2, 0.7%) where the lesions preceded malignancy by 3 months and 1 month respectively. Contiguous nodules were a marker of relapse after surgery in 3 (1%).
RESUMEN
Hypertension is a major public health problem both in the developing and developed countries of the world and if untreated, can lead to various fatal complications like cerebral stroke, encephalopathy, ischaemic heart disease (IHD), renal failure and sudden cardiac death, etc. In the present study, a comparative evaluation was made between angiotensin-II receptor antagonists like losartan potassium (50 mg daily) and angiotensin converting enzyme (ACE) inhibitors like enalapril maleate (5 mg daily) in 100 patients (50 males and 50 females having 25-50 years of age) of mild to moderate essential hypertension with diastolic blood pressure (DBP) 90-109 mmHg. Both the drugs were tried as monotherapy for their clinical efficacy, safety, tolerability and adverse effect profile in this open trial. Losartan potassium lowered the DBP to <90 mmHg in 62% of the patients at the end of 8 weeks compared to 40% in the enalapril group. Percentage of side effects with losartan was 20 and 50 with enalapril. It is concluded that both the drugs are effective antihypertensive agents and cause significant and comparable fall in systolic blood pressure (SBP) and DBP in patients of mild to moderate essential hypertension. But losartan potassium has been found to be more effective with fewer side effects when compared to enalapril maleate.

OBJECTIVES: The present study was designed to evalutate the association of various risk factors such as smoking, alcohol, NSAIDs, inadequate dietary intake of fibres and consumption of spicy foods with chronic duodenal ulcer using a case-control design and to establish the association of Helicobacter pylori and duodenal ulcer using different diagnostic techniques in Indian subjects. MATERIALS: A total of 16 consecutive patients with endoscopically proven duodenal ulcer (DU) constituted the test group while 160 subjects with non-ulcer dyspepsia (NUD) were recruited as controls. METHODS: All subjects were interviewed based on a standard questionnaire and underwent an upper gastrointestinal endsocopy wherein multiple biopsies were taken for rapid urease test (RUT), histology and culture for detection of H. pylori. The serum samples of all the subjects were tested for the presence of antibodies against H. pylori using ELISA. RESULTS: There were significantly greater number of smokers (80%) and alcoholics (58%) in the male population of DU group as compared to the controls (49% smokers & 15% alcoholics). Similar trend was seen in relation to history of chronic exposure to NSAIDs (29% in DU & 11% in NUD) and inadequate intake of fibre in diet (66% and 39% respectively). The overall prevalence of H. pylori was 82.5% in DU and 50.6% in NUD [p < 0.001]. CONCLUSIONS: In North Indian subjects, alcohol consumption, smoking, inadequate intake of fibre in diet and use of NSAIDs are the risk factors associated with doudenal ulcer disease. Further, infection with H. pylori is strongly associated with DU in the North Indian population.

A study was undertaken to evaluate the efficacy of multidrug therapy as per WHO recommendation in 50 fresh cases (46 males and 4 females) suffering from borderline tuberculoid leprosy. All were given multidrug therapy consisting of rifampicin 600 mg once a month and dapsone 100 mg daily for 6 months. At the end of 6 months all were evaluated clinically and histopathological examinations of the lesions were studied. The lesions were still active in 60% of patients clinically; 32% cases receiving multidrug therapy had shown marked improvement. Histologically lymphocytic infiltration in skin still persisted in all the slides examined and nerve infiltration was still present in 68% of cases at the end of 6 months after receiving multidrug therapy. The study shows that treatment with multidrug regimen for 6 months may not be sufficient to treat borderline tuberculoid leprosy cases.

One hundred twenty histologically confirmed cases of leprosy having macular lesions were evaluated clinically and histopathologically according to Ridley-Jopling classification. Of these 120 cases, the majority (91 or 75.8%) were young adults. The main clinical findings were: a single macule in 42 patients (35%), multiple macules 2-5 in numbers in 35 patients (29.1%), 6-10 macules in 17 patients (14.1%) and more than 10 macules in 26 patients (21.6%). Impairment of sensation over the macular lesions was present in 62 cases (51.6%), total loss of sensation was noticed in 31 patients (25.8%) and sensation was intact in 27 patients (22.5%). Acid-fast bacilli were detected in 11 cases (9.1%) by slit-skin smear examination. Clinical examination of the 120 cases revealed features of TT in 16 (13.3%), BT in 41 (34.1%), BB in 11 (9.1%), BL in 13 (10.8%), LL in 7 (5.8%) and indeterminate leprosy (IL) in 32 patients (26.6%). On the contrary, histologically there were 22 cases of TT (18.3%), 38 cases of BT (31.6%), 8 (6.5%) BB, 10 BL (8.3%), 7 LL (5.8%) and 35 cases of IL (29.1%). Histopathological features were consistent with the clinical picture in 84 patients (70%).

Fifty two children (upto 12 years age) with acute renal failure (ARF) admitted to the Nephrology services between January, 1989 to August, 1992 were studied to determine the cause and outcome. Of these, 39 were boys and 13 girls; 27 (51.9%) patients were below 4 years of age. Hemolytic uremic syndrome (HUS) was the commonest cause of ARF (30.8%) followed by acute tubular necrosis (ATN) in 28.84% and acute glomerulonephritis in 19.23%. All patients had severe renal involvement with anuria in 53.6% and oliguria in 46.4% at presentation. HUS was the leading cause of anuria (53.6%), followed by obstructive uropathy (21.4%). Thirty five patients required dialytic support for a median duration of 18 days (2-90 days). The mortality was 34.6%. Seven patients of HUS, 4 patients of ARF following surgery, 3 patients each of ATN and glomerulonephritis and one patient of obstructive uropathy died. Anuria at onset, central nervous system or respiratory complications and delay in institution of dialytic support were bad prognostic factors. We conclude that early referral and prompt institution of dialytic support may be helpful in decreasing the mortality.

Forty renal transplant recipients were subjected to 99m Technicium Diethylene triamine pentacetic acid (DTPA)scans at regular intervals & whenever there was suspection of rejection. Serial scans of a group of 15 recipients from immediate post transplant period till withdrawal of cyclosporine were analysed separately & the results compared to with single scan analysis. The sensitivity & specificity of DTPA scan in the absence of acute tubular necrosis (ATN) was 94.1% & 87.5%, while the positive & negative predictive values were 88.8 & 93.3% respectively. Sensitivity & specificity of serial scan analysis (88.8% and 75%) in early post transplant period was higher than that of interpretation of single scan (75% & 66%). Serial scan changes predated clinical rejection during cyclosporine withdrawal period. We conclude that DTPA scan is both a sensitive & specific non-invasive diagnostic marker of acute rejection in absence of ATN & serial scans during early post transplant period & at the time of cyclosporine withdrawal are helpful in detecting the rejection accurately & at the earliest.
