Serum urea, creatinine and electrolyte status in patients presenting with acute gastroenteritis.

The present study was undertaken to estimate the serum urea, creatinine and electrolyte status of patients presenting with acute gastroenteritis. Sixty patients who presented to Kathmandu Medical College and Teaching hospital from 15 June to 15 July 2005 with acute diarrhea with or without associated vomiting, causing dehydration severe enough to require hospital admission were investigated for serum urea, creatinine and electrolyte level. Out of 60 patients investigated, serum sodium and potassium level were available for 34 patients. Only one (2.9%) patients had sodium level below 135mEq/l, thirty two (94.11%) had sodium level between 135-146 mEq/l and one (2.9%) had sodium level above 146mEq/l. Similarly 9 (26.47%) patients had potassium level below 3.5mEq/l, 22 (64.70%) patients had potassium level between 3.5-5 mEq/l and 3 (8.82%) patients had level above 5 mEq/l. Serum urea and creatinine level were available for 47 patients. 36 (76.59%) patients had serum urea level between 15-45mg/dl and 11 (23.40%) patients had urea level above 45 mg/dl. 35 (74.46%) patients had serum creatinine level between 0.5-1.4 mg/dl and 12 (25.53%) had serum creatinine level above 1.4 mg/dl. In this study hypokalaemia was noticed more than hyponatremia and significant number of patients also showed increased level of serum urea and creatinine. Therefore, serum urea, creatinine and electrolytes should be closely monitored in patients with acute gastroenteritis.

Correlation between serum-ascites albumin concentration gradient and endoscopic parameters of portal hypertension.

OBJECTIVE: We sought to determine the correlation between the level of serum-ascites albumin concentration gradient (SAAG) and the complications of portal hypertension (PHTN), manifested by the presence and grade of esophageal varices (EV). MATERIAL AND METHODS: Our study included 32 patients with ascites, demonstrated by ultrasonography, who had measurement of the SAAG. All had upper gastrointestinal endoscopy with assessment of the presence and size of EV. High SAAG was considered to be present when SAAG was >=1.1 g/dl and Low SAAG when it measured < 1.1 g/dl. RESULTS: We found that 25 of 32 (78.13%) patients had High SAAG and 7 of 32 (21.87%) had Low SAAG. Esophageal varices were present in 18 of 25 (72%) patients with High SAAG and in none of 7 (0%) patients with Low SAAG (p =<0.001). Among patients with High SAAG, EV were present in four of 8 patients (50%) with SAAG values of 1.10-1.49g/dl; in four of seven patients (57.1%) with SAAG values of 1.50-1.99g/dl; and in ten of ten (100%) with SAAG values of >=2.0g/dl (p = 0.037). The size of the esophageal varices had no association with the level of SAAG in patients with High SAAG (p = 0.426). CONCLUSIONS: In patients with ascites the presence of esophageal varices is associated only with patients with High SAAG. The presence of EV in patients with ascites and High SAAG is directly related to the degree of SAAG. The size of the EV in patients with ascites and High SAAG is not associated with the degree of SAAG.

Study of clinical profile and antibiotic sensitivity pattern in culture positive typhoid fever cases.

OBJECTIVES: The present study was designed to analyze the clinical profile and antibiotic sensitivity pattern in the cases of culture positive typhoid fever. METHOD: The study was conducted over a period of 1 year. Total of 46 culture positive cases of Typhoid fever were included in the study. The sensitivity pattern of isolates from blood culture was recorded. The modes of presentation, clinical course, lab investigation reports were also recorded. RESULTS: Out of 46 cases, 33 (71.7%) were males and 13 (28.3%) were females. Average age of presentation was 26.17 years. Fever was present in all patients. Resistance of S .typhi to amoxycillin, chloramphenicol and co-trimoxazole were significantly high. Ciprofloxacin showed resistance in 2 (4.3%) cases. Sensitivity to ceftriaxone was 100% in our study. CONCLUSION: Typhoid fever is one of the most common health problem in Nepal. Various drugs are being used in the treatment of typhoid fever, in the mean time resistance to many of them are emerging. An appropriate antibiotic has to be initiated only after culture sensitivity in typhoid fever.

Injection drug use and tricuspid valve endocarditis.

Tricuspid valve endocarditis is more common in injection drug users. Pulmonary valve and Eustachian valve endocarditis have been reported but are very rare. Earlier reports of endocarditis in injection drug users emphasized the dominance of right sided involvement. In a series of 105 patients 86 % were right sided and 14 % had left sided involvement. We report a case of isolated tricuspid valve endocarditis in an injection drug user affecting a structurally normal heart and review of the literature on this subject. Key Words: injection drug use, tricuspid valve endocarditis.

HIV/AIDS and STI related knowledge, attitude and practice among high school students in Kathmandu valley.

OBJECTIVE: To assess the knowledge, attitude and practice of high school students regarding HIV/ AIDS and STI and to determine if a school education programme would bring about statistically significant positive change in the knowledge, attitude and practice regarding HIV/AIDS and STI. METHODS: The study was conducted among 1012 students of various schools in Kathmandu Valley (Kathmandu, Bhaktapur and Lalitpur). The tool for assessment was confidentially administered closed questionnaire both before and after the education programme of 45 minutes single class, standardized education package. RESULTS: Knowledge on some aspect of the disease was quite low in the study group. 45.8% had prior knowledge of HIV, 65.2% knew that HIV/AIDS could be transmitted by sharing same needle, 46.2% knew that vaccine is not yet available for HIV/AIDS. Knowledge about STI was also quite low, 41.5% knew that pus in the urine is a symptom of STI and 41.7% knew that STI is curable. 4.2% of the study group had previous sexual intercourse, 64.2% had sexual intercourse with friend and 35.17% had sexual intercourse with commercial sex workers. 1.8% would commit suicide if they contracted HIV/AIDS. According to sex wise distribution of the sample, female's knowledge about HIV was low 43.2% as compared to male 48%, male's knowledge about transmission of HIV/AIDS from pregnant mother to child was low; 89.7% as compared to female's knowledge 94.2%. Female's knowledge about commercial sex worker as high risk group was low (87.8%) as compared to male's knowledge 90.6%.

Knowledge, attitude and practices among health care workers on needle-stick injuries.

OBJECTIVE: This study aimed to assess the knowledge, attitude and practices among health care workers on needle stick injuries. METHODS: A 15-item questionnaire was administered to seventy health care workers including nurses and paramedical staffs from different departments of Kathmandu Medical College and Teaching Hospital to measure knowledge, attitude and practices on needle stick injuries. RESULTS: Results showed that 4% and 61% of health care workers, respectively, were unaware of the fact that hepatitis B and hepatitis C can be transmitted by needle-stick injuries. 52 subjects (74%) had a history of needle-stick injuries and only 21% reported the injuries to the hospital authority. Only 23% were in the habit of using gloves for phlebotomy procedures all the time. 79% were of the impression that needle should be recapped after use. Only 66% were aware of Universal Precaution Guidelines. 16 subjects (23%) were negative for HBsAg, Anti-HCV and Anti-HIV and 54 subjects (77%) do not know about their immune status. 42 subjects (60%) had been vaccinated against hepatitis B, while 28 subjects (40%) were not vaccinated against hepatitis B. Only 6 subjects (14%) had been tested for Anti-HBs antibody after hepatitis B vaccination. CONCLUSION: The survey revealed that knowledge of health care workers about the risk associated with needle-stick injuries and use of preventive measures was inadequate. A standing order procedure (SOP) should be formulated regarding needle-stick injuries in all the health institutions. It should outline precautions to be taken when dealing with blood and body fluids. It should also contain reporting of all needle-stick injuries. Health care workers should be made aware of hazards, preventive measures and post-exposure prophylaxis to needle-stick injuries. A hospital-wide hepatitis immunization programme should also be started.

Clinical profile of typhoid patients.

OBJECTIVE: The present study was undertaken to determine the clinical profile of typhoid fever in hospitalised patients. DESIGN: Prospective cross-sectional study. SETTING: Kathmandu Medical College and Teaching Hospital. METHOD: Total of thirty patients above fifteen years of age who had clinical features strongly suggestive of typhoid fever and on blood culture found to be positive for Salmonella typhi were analysed for clinical features. RESULT: Among total of thirty cases, there were 17 (57%) males and 13 (43%) females. 86% of cases of typhoid fever clustered around 15-30 years of age. Predominant symptoms were fever (100%), headache (90%), abdominal Pain (37%) and constipation (33%). Common clinical signs were splenomegaly (37%), relative bradycardia (27%) and hepatomegaly (17%). None of the patients presented with complications. CONCLUSION: The clinical profile of typhoid fever in our study revealed not much difference from that of other studies on typhoid fever. Rose spots were not noticed and we did not find a single case of complication of typhoid fever. Probably early initiation of antibiotics prevented the complications.
