  ABSTRACT: Hypertension and Chronic kidney disease (CKD) are common in Nepal. Control of blood pressure (BP) in general hypertensive patients is poor. Evaluation of adequacy of BP control in CKD patients with hypertension is rare. All consecutive indoor patients (52) with CKD and hypertension, attending echo-lab of Nepal Medical College Teaching Hospital during prospective study of 3 years period from 16th April 2008 to 15th April 2011, were evaluted. Mean age was 45.3 +/- 16.7 years. Male female ratio was 8:5. Brahman and Chhetri (22, 42.3%) were the usual sufferers. There were two peaks in the age group wise distribution; one in age group 20-29 years and the next in 50-59 years. One hypertensive patient's BP was normalized after starting hemodialysis without antihypertensive therapy and was excluded from this study. Others' BP (n = 51) were followed up during admission for the evaluation of the adequacy of their BP control and their antihypertensive medications were reviewed. The control of hypertension in CKD patients was difficult. More than two third of the patients (68.6%) had BP > 140/90 mm Hg. Intensive BP control was present in less than one tenth (7.9%) of the patients. In comparison to intensive group, uncontrolled group received more antihypertensive agents (3.0 +/- 1.3 vs. 2.0 +/- 0.8, p < 0.05). Amlodipine (39, 76.5%) and frusemide (39, 76.5%) were very popular antihypertensives used followed by Prazocin (20, 39.2%) and Metoprolol (11, 21.6%). Despite good efforts, BP control of Nepalese CKD patients with hypertension, were poor.

  ABSTRACT: Poisoning is an increasingly common social problem in Nepal. Studies on poisoning in semi urban areas of Nepal are minimal. Here we, present a prospective study of poisoning in semi urban area of capital, Kathmandu lasting for six years duration. Altogether there were 354 cases of various poisoning, admitted in Nepal Medical College Teaching Hospital from Baisakh 2062 (April 16, 2005) to Chaitra 2067 (April 15, 2011). Male: Female ratio was 135:219 (1:1.6) and Age +/- SD was age 29.3 +/- 13.8 years. Age group (20-29 years) comprised of 138 patients (38.9% followed by < 20 years age group (92, 25.9%). Brahman/ chhetri (150, 42.4%) and Mongolian (146, 41.2%) ethnic groups were the main sufferers of poisoning, followed by newars (41, 11.6%) patients. Deliberate self harm was the cause for poisoning in maximum number of patients (156, 44.1%), followed by depression (64, 18.1%) and accidental poisoning (42, 11.9%). Organophosphorus (152, 42.9%), medicines (71, 20.1%), and rodenticide poisoning (38, 10.7%) were common poisons. Metacid (Methyl parathion) (46, 15.5%) was the most popular brand of poisoning agent used in Nepal for suicidal purpose. The over all mortality rate of poisoning in general was 7.1% with organophosphorus poisoning topping the list (19, 12.5%). We also present mad honey poisonings in a small group of 9 (3.2%) patients with M:F 8:1, age 26.5 +/- 8.8 years. Due precaution should be undertaken during their management as some of them may go into cardiopulmonary arrest and should not be considered benign when more than 5 tablespoonful wild honey is consumed.

  ABSTRACT: The present study was undertaken to assess the difference between the normal predicted value and observed value of pulmonary function test (PFT) amongst the asthmatic patients and also to compare the aforesaid observed values between male and female asthmatic patients. Clinically diagnosed cases (male 62, female 75) of bronchial asthma attending medical out patient department of Nepal Medical College Teaching Hospital were assessed. All the pulmonary parameters showed significantly less observed values than the normal predicted values except PEFR in female and FVC in male asthmatic patients. Hence, PEFR in female and FVC in male asthmatic patients might not be considered as a valid parameter to indicate bronchial asthma. Present study also revealed that all the pulmonary variables were significantly higher in males than in females.

  [show abstract] [hide abstract]
  ABSTRACT: Chronic obstructive pulmonary disease (COPD) is the most common medical problem in Nepal. Echocardiography based cardiac evaluation in COPD is rare in Nepal. The purpose of this study is to evaluate the echocardiography based cardiac function in consecutively admitted COPD patients (507) in medical wards of Nepal Medical College Teaching Hospital during 13th April 2007 to 12th April 2008. Male female ratio was 0.9:1. Age (mean +/- SD) was 66.1 +/- 10.9 yr. Brahman and Chhetri ethnic group comprised of more than half of total COPD patients followed by similar number of patients in Newar (22.1%) and Mongolian ethnic groups (21.5%). More than half of the COPD patients were in age group 60-75 years, followed by less number of patients (approximately 20.0%) in both 45-59 years and 75-89 years age groups. Of the total patients (507), 141 patients underwent echocardiographic evaluation. Among them significant number of patients had poor LVEF (29, 20.6%) with statistically significant difference in LVEF (36.0 +/- 10.5 vs. 64.3 +/- 8.5%, p value < 0.01). More than half of the total patients showed features of chronic cor pulmonale (56.3%), followed by valvular heart disease (49.3%), diastolic dysfunction (38.7%) and left ventricular hypertrophy (14.1%). Mild pulmonary artery hypertension (PAH) was detected in approximately half of patients (49.1%), followed by moderate PAH in 17.6% patients. Transthoracic echocardiography was found to be very useful to identify various concomitant cardiac abnormalities demanding special treatment consideration in managing clinically COPD like patients.

  [show abstract] [hide abstract]
  ABSTRACT: Reporting system after performing echocardiography is very poor in almost all hospitals of Nepal. Special but simple attempt effort has been introduced to transfer analog video images and color still images of echocardiographic investigation into a desk top computer using a locally available imported video capture system, Snazzi Movie Studio S4. Analog video signals are converted into MPEG2 and still color snaps are converted into JPEG format. Window media player can be used later on to review the video clips. All together 1059 patients including pediatric, adults and geriatric patients underwent echocardiographic evaluation at the Echo-lab of Nepal Medical College Teaching Hospital during 10th January 2007 to 9th May 2008. Age ranged from 2 months to 98 years. Mean+SD was 52.4 +/- 18.5 years. Male/female ratio was 0.8:1. More than half of the patients (64.3%) came from Kathmandu. Brahman/Chhetri (478, 45.1%), Tamang, Sherpa etc 278 (26.3%) and Newar (226, 21.3%) were the main echo-users. Elderly age group (>60 yr) comprised of more than one third of the patients (42.0%) followed by the age group of 45-59 yr (27.7%). No abnormality was detected in 133 (12.6%) patients. Valvular heart disease was noticed in more than half of patients (60.7%), followed by diastolic dysfunction (393, 14.0%) and left ventricular hypertrophy (210, 7.5%). This database is not very expensive but demand minimal extra time and energy. It will be a valuable tool to increase diagnostic accuracy and a great resource for academic purpose aiding in the improvement of cardiac care in Nepal.

  ABSTRACT: Automatic ambulatory blood pressure monitoring (ABPM) for the diagnosis and treatment ofhypertension(HTN) is not common in Nepal. The purpose of this study is to evaluate various characteristics of hypertensive patients undergoing ABPM before starting antihypertensive treatment and evaluate the adequacy of the blood pressure (BP) control during antihypertensive treatment. ABPM was performed in 108 consecutive patients attending the hypertension clinic of Nepal Medical College Teaching Hospital from 1st March 2005 to 30th April 2007 with DynaPulse 5000A (version 3.20q ) for approximately 24 hours. Male female ratio was 59:49 and age (mean +/- SD) was 47.8 +/- 16.4 years. The maximum use of ABPM (25.9%) was noted in the age group of 40-49 years. Body mass index was 25.7 +/- 3.8. Diabetes was noted in 13% patients. Maximum use of ABPM was observed in Newar ethnic group (56.5%). ABPM was used for the diagnosis of HTN in 62.0% patients and for follow up in 38.0% patients. Severe HTN was seen in approximately half (47.2%) of the hypertensive patients. Majority of the patients (88.0%) had dipper type of HTN. Beta-blocker (35.6%), ACE inhibitor/Losartan (31.1%) and calcium channel antagonist (26.7%) were the usual antihypertensive agents used. Single antihypertensive agent was used in the majority of patients (64.1%). In a small number of patients (42, 38.9%) undergoing ABPM during antihypertensive therapy, the adequacy of control of HTN was very poor.
