Publication An outbreak of El Tor cholera in Kavre district, Nepal(Kathmandu University, 2005) Tamang, MD; Sharma, N; Makaju, RK; Sarma, AN; Koju, R; Nepali, N; Mishra, SKOutbreak of Cholera still remains major public health problem in most of the developing countries including Nepal. A prospective study was carried out at Dhulikhel Hospital, Kathmandu University Teaching Hospital, Kavrepalanchok during 1st May 2004 to 31st October 2004. A total of 148 stool samples from patients with acute diarrhea were collected and further investigated for Cholera. The study was conducted to establish the causes of the outbreak of acute diarrheal disease, antimicrobial profiles of the stool isolates and parasitic co –infection in Cholera cases. The samples were subjected to standard recommended microbial procedures and confirmation of the isolates was done by seroagglutination using V.cholerae polyvalent O1 and 0139 antisera and monovalent Ogawa and Inaba antisera. Out of the 148 stool samples, 46 cases (31%) were found to be positive for V.cholerae serogroup O1, biotype ElTor, serotype Ogawa. Both sexes were equally affected. Young age group of less than 30 years were mostly affected. Brahmin was the most affected ethnic group. The isolates were sensitive to all the antibiotics tested except co-trimoxazole. Among the laboratory confirmed cholera cases 30% exhibited co-infection with other parasites among which Giardia lamblia and Ascaris lumbricoides were the most common.

Material and Method: This is a prospective study carried out at Manipal Teaching Hospital, Pokhara during May 2002 to April 2003. A total of 716 sputum samples collected from patients with suspected lower respiratory tract infection were investigated. The samples were subjected to Gram stain, culture and sensitivity. Sputum samples were inoculated on blood and chocolate agar and incubated at 370C for 18 to 24 hours in candle jar containing 3-5% Co2. For the identification of bacterial isolates, the cultural and colonial characteristics were recorded and identified with the use of biochemical test. The susceptibility of bacterial isolates to antimicrobial agent was performed following Kirby-Bauer method. Result: Out of the 716 samples, 355 (49.58%) grew normal commensals of the upper respiratory tract. Respiratory pathogens were recovered from 361 (50.41%) samples. The most common respiratory pathogen was H. influenzae (26. 86%), followed by S. pneumoniae (21.16%). Moraxella catarrhalis accounted for 6.90%. Rate of isolation of Moraxella catarrhalis was higher in males than in females. Out of 25 isolates 16 were from males and 9 were from females. Frequency of isolation of Moraxella catarrhalis was more frequently seen in age group 61-70 years. It was most commonly recovered in winter. The most effective antibiotics were amoxicillin-clavulanate and ceftriaxone and least was ampicillin. Conclusion: Moraxella catarrhalis isolation from sputum especially in persons above 60 years of age and in the absence of other well established pathogens should not be disregarded as they can cause lower respiratory tract infection in these individuals.

Thus, thyroid disorder is usually associated with the dyslipidaemia. Hypercholesterolemia is an established risk factor for the cardiovascular disease (CVD) and therefore in case of overt hypothyroidism which is associated with hypercholesterolemia, CVD is most likely to occur. Objectives: controversies still persist about the hypercholesterolemia and sub clinical hypothyroidism. Hence, we conducted our study to elucidate the relation of thyroid hormone with cholesterol in different thyroid disorder. Material and Method: All patients suspected of thyroid disorder within a period of one year were included in the study and free thyroxine-3 (fT3), free thyroxine-4 fT4, Thyroid Stimulating Hormone (TSH) and total cholesterol (TC) in the serum were estimated. Statistical analysis was carried out by using SPSS. 13. Results: Among the 169 cases, 32.5% of the patients were having thyroid disorder. In which 8.3% were of hypothyroid, 7.1% were of sub clinical hypothyroid, 8.3% were of hyperthyroid, 7.7% were of sub clinical hyperthyroid and 1.2% cases were of pan hypothyroid. We observed significant negative correlation between TC & fT3(r = -0.226, p = 0.003), significant negative correlation between total cholesterol & fT4(r = -0.197, p = 0.010) and significant positive correlation between TC & TSH(r = 0.365, p = 0.000). Total cholesterol was significantly raised in hypothyroidism (Mean ±SD 283±53, p = 0.000) in comparison to euthyroid population (mean ±SD, 195±58). But cholesterol was not significantly increased in sub clinical hypothyroidism (mean ±SD, 240±46) Conclusion: Our results show that total cholesterol level in serum is affected by the blood thyroid hormone level. Therefore, screening for hypercholesterolemia could be useful in patients with hypothyroidism to reduce associated disease. Key words: Thyroid hormone, Cholesterol, Nepal
