Item Acute aluminum phosphide poisoning--an epidemiological, clinical and histo-pathological study.(1988-10-01) Siwach, S B; Yadav, D R; Arora, B; Dalal, S; Jagdish,Item Acute effects of ethyl alcohol on left ventricular performance in myocardial infarction cases--a study of systolic time intervals.(1985-06-01) Siwach, S B; Gupta, S P; Lohan, AItem Age and sex related trends in blood pressure in the general population of Haryana.(1979-05-01) Gupta, S P; Siwach, S B; Moda, V KItem Aortic saddle embolus.(1992-01-01) Siwach, S B; Gupta, SItem Cardiac arrhythmias in aluminium phosphide poisoning studied by on continuous holter and cardioscopic monitoring.(1998-07-03) Siwach, S B; Singh, H; Jagdish,; Katyal, V K; Bhardwaj, GVariable incidences of cardiac arrhythmias (based on isolated 12 lead ECG records) have been reported in patients of aluminium phosphide (ALP) poisoning. We did continuous holter and cardioscopic monitoring in ICU in 30 patients of acute ALP poisoning. Supraventricular and ventricular ectopics were recorded in each and every patient. Life threatening ventricular tachycardia was recorded in 40% cases and ventricular fibrillation in 23.3% cases. Supraventricular tachycardia and atrial flutter/fibrillation occurred in 46.7% and 20% patients, respectively. ST-T changes simulating myocardial ischaemia were also present in all patients (S-T depression in 90%, S-T elevation in 10%). One-third of the patients developed variable degrees of heart block, IV amiodarone/xylocard could revert dangerous ventricular arrhythmias to sinus rhythm in 4 cases. Toxic myocarditis produced by phosphine seems to be responsible for the development of these arrhythmias.Item Case report. Tuberculous abscess of the liver.(1978-07-01) Siwach, S B; Srivastava, S CItem The changing profile of Plasmodium falciparum malaria.(1997-01-01) Katyal, V K; Singh, H; Siwach, S B; Jagdish,; Lahri, S; Basu, MResurgence of malaria has been noted in the Rohtak district (Haryana, India) after the recent floods. The profile of 66 patients of P. falciparum infection who were admitted to our hospital over one month in October 1995 is reported. While only a minority of cases (< 15%) presented with an uncomplicated course, all others developed one or more complication(s), some of them very rare. The usual manifestations viz, cerebral malaria, black water fever and algid malaria seen in the past were observed in less than half the patients. The remaining presented with unusual complications like haemolytic anaemia (46.2%), severe anaemia (37.9%), thrombocytopaenia (18.2%), pancytopaenia (6%), adult respiratory distress syndrome (4.5%) often not seen in sporadic cases of falciparum malaria which occurred in the past in this district. Similarly all deaths (15.1%) were noted in patients with rarer manifestations and only one patient died of cerebral malaria. This study confirms the occurrence of severe and complicated falciparum malaria in this part of the country.Item Chronic lymphocytic leukemia manifested by steroid responsive polyneuropathy.(2003-01) Rajput, Rajesh; Batra, Munish; Siwach, S B; Jagdish, JagdishWe report a patient of acute demyelinating polyneuropathy who on investigations turned out to be suffering from chronic lymphocytic leukaemia (stage 0). Response to steroid therapy suggests an autoimmune process as a cause of polyneuropathy. Chronic lymphocytic leukaemia manifested by acute polyneuropathy has been described rarely in literature.Item Comparative evaluation of dopamine infusion & treadmill exercise tests in the diagnosis of coronary artery disease.(1993-10-01) Siwach, S B; Sharma, D; Dua, ADopamine infusion test (DIT) was compared with treadmill exercise test (TMT) in 20 patients of chronic stable angina (TMT +ve) for inducing reversible myocardial ischaemia so as to assess its efficacy as an alternative to TMT in patients who cannot perform exercise test due to certain non-cardiac diseases. DIT was positive in 15 of the 20 patients studied; five patients in whom DIT was negative had late onset, early offset changes in TMT. Haemodynamically the increase in heart rate (HR) was less but rise in systolic blood pressure (SBP) was more with dopamine infusion in comparison to the corresponding stage of TMT. However, evidence of myocardial ischaemia (ST segment depression) appeared at a lower rate pressure product (RPP) with dopamine infusion compared to exercise test. The test was tolerated well, in higher doses (stages III & IV) side effects like ventricular ectopic beats, palpitation and angina not warranting stoppage of test, were seen in some patients. Dopamine infusion is a good chemical stress test, and can be used as an alternative to TMT especially in situations where the latter cannot be performed. The test is simple, cost effective, non-invasive and well tolerated.Item A comparative study of captopril & propranolol in essential hypertension.(1987-09-01) Singhal, K; Siwach, S B; Gupta, D K; Gupta, S PItem Comparative study of cigarette and bidi smoking on left ventricular performance as determined by systolic time intervals.(1985-07-01) Gupta, S P; Siwach, S B; Manmohan,; Gupta, M SItem DC cardioversion and coronary artery spasm.(1989-08-01) Siwach, S B; Katyal, V KMarked ST segment elevation which occurred following DC shock given for conversion of lone atrial fibrillation in a 55 years old male is reported. This was possibly coronary artery spasm induced by direct current and adds one more complication to the many already described.Item Diaphragmatic hernia masquerading as hydropneumothorax.(1995-10-01) Siwach, S B; Katyal, V K; Jagdish,; Sharma, D; Dhull, J CItem Effect of atenolol and labetalol on serum lipids.(1993-05-01) Siwach, S B; Dahiya, S S; Seth, S; Seth, R K; Sharma, DAdverse alterations in lipid profile suggesting higher atherogenicity were observed following 12 weeks treatment with atenolol in patients of hypertension. No significant alterations in lipid profile were observed with labetalol therapy.Item Epidemiology of hypertension based on total community survey in the rural population of Haryana.(1977-03-01) Gupta, S P; Siwach, S B; Moda, V KItem Epidemiology of hypertension. Based on total community survey in the urban population of Haryana.(1978-11-01) Gupta, S P; Siwach, S B; Moda, V KItem Estimation of 24 hour protein excretion from single random urine specimen.(1990-04-01) Siwach, S B; Kalra, O P; Sharma, R; Singh, V; Chopra, J SThe product of protein/creatinine ratio (in a random urine specimen) and estimated daily urinary creatinine excretion were evaluated as a function of 24 h urinary protein excretion in 40 patients with pathology proteinuria having varying grades of renal function. An excellent correlation was found between the results obtained by this method and those from the standard 24 h urine collection method in healthy controls (r = 0.99) and in patients with normal (r = 0.88) or mild to moderately impaired renal function (r = 0.99). However, this method did not give a good measure of quantitative proteinuria in patients with advanced renal failure (r = 0.56), possibly due to decreased urinary excretion of creatinine in patients with advanced renal failure as compared to the estimated value. The product of protein/creatinine ratio and estimated daily urinary creatinine excretion thus gave a quick and alternate reliable method of estimating 24 h proteinuria in patients having normal or mild to moderately impaired renal function. However, this method is not suitable for patients with advanced renal failure.Item Hypertension and blood pressure trends in the general population of Haryana (based on total community surveys).(1979-02-01) Gupta, S P; Siwach, S B; Gupta, M SItem Intracardiac mass lesions: experience of 14 cases.(1999-07-05) Siwach, S B; Katyal, V K; Jagdish,Mass lesions within the heart are often encountered during routine echocardiography. The nature of such masses can generally be suspected depending upon clinical setting. During 13 years of our experience in echo lab, we came across 14 patients with large intracardiac masses (some of them, rare type). Clinical features, echocardiographic findings and histopathological confirmation which was possible in majority of them, are described. Five of our patients had cardiac tumour (myxoma), four had large intracavitary thrombus, while pieces from two patients were demonstrated to have large vegetations and hydatid cyst(s). One patient, suspected to have vegetation on mitral valve, turned out to have thick myxomatous tissue deposits on histopathology. Two-dimensional echocardiographic features of intracardiac mass lesion are generally dependable in deciding nature of such lesions. However, very large thrombus and vegetation mimicking cardiac tumour are rarely encountered.Item Left atrial ball thrombus: echocardiographic features and clinical implications.(1994-08-01) Dua, A; Sharma, D; Siwach, S B
