Culdocentesis is a procedure that checks for abnormal Quid in the space just behind the vagina (cul-de-sac). First, a pelvic examination is done. Then, after exposing the postehor vaginal fonix with a bivalve vaginal speculum the posterior lip of the cervix is grasped with a tenaculum. The cul-de-sac is then entered through the postehor vaginal wall with an 18-20 gauge needle with a syringe inserted. As the cul-de-sac is entered, suction is applied, and the intraperitoneal contents are aspirated. In the recent past, culdocentesis was commonly used in the evaluation of a vahety of common intraperitoneal conditions, principally, the hemorrhage associated with ectopic gestations and ruptured ovarian cysts the presence and/or drainage of purulent associated with pelvic inGammatory disease, and as a screening procedure to facilitate early diagnosis of ovarian neoplasms. Usually 16-18 gauge needle with a syhnge attached was used for culdocentesis. But we have experienced a case of therapeutic culdocentesis with 16 gauge angioneedle in patient of hemoperitoneum. So, report it with a bhef review of literature.

Helicobacter pylori infection was the cause of chronic gastritis, duodenal ulcer and gastric MALT lymphoma. The eradication rates of H. pylori using antibiotics are around 80%. Lactobacilli have been demonstrated to have in vivo and in vitro inhibitory effects on H. pylori infection. We aimed to evaluate the inhibitory effect of L. lactis CBT-8 and its extract on H. pylori in human stomach. Thirty-five H. pylori-infected volunteers(30-49 yr)were randomized into two groups which were treated with L. lactis CBT-8 and its extract(Group A n=17) or milk containing L. lactis CBT-8(Group B, n=18). They underwent 13C-urea breath tests before and after treatment. The DOB30 of group A(n=14) was decreased 41.0% after treatment(26.0±4.9 before, 15.3±2.1 after treatment)(p<0.05). the DOB30 of group B(n=13) was decreased 22.3% after treatment(22.0±2.2 before, 17.1±1.7 after treatment)(p<0.05). In conclusion, L. lactis CBT-8 was effective in suppressing H. pylori infection in human stomach.

Objectives: Present study was conducted to evaluate work-related symptom prevalence among hairdressers. Methods: Exposed group comprised 184 employee employed 73 hair salons in 6 district of Pusan city, and non-exposed group comprised 119 people living recent apartments. A trained interviewer interviewed them with organised questionnaire which included dermatologic, respiratory and musculo-skeletal symptoms. Results : Prevalence of hand eczema was 28.3% in exposed group, and 5.8% in non-exposed group. Adjusted odds ratio for age and atopy history was 4.30(2.34-7.93). Prevalence of respiratory symptom (coughing) in exposed group was 22.1%, and 9.4% for non-exposed group. Adjusted odds ratio for coughing which was adjusted for age, smoking and atopy history was 2.76(1.32∼5.78). Prevalences of musculo-skeletal symptoms among exposed group were neck(59.9%), shoulder(76.6%), upper back(41.2%), lower back(72.2%), arm and elbow(31.3%), wrist(44.2%), finger(35.0%), leg(71.1%). Adjusted Odds Ratios for musculo-skeletal symptoms which was adjusted for age were neck 2.13(1.29∼3.51), shoulder 2.52(1.50∼4.24), upper back 1.71(1.01∼2.88), lower back1.78(1.06∼2.99), arm and elbow 3.10(1.62∼5.94), wrist 2.09(1.23∼3.57), finger 4.83(2.41∼9.68), leg 3.46(2.07∼5.79). Conclusions : These results show that employees in hair salon are likely to have high risk for work-related dermatologic, respiratory and musculo-skeletal symptoms and diseases. Hence, prevention methods from those work-related diseases are required to be developed. Also, the scope of occupational and environmental medicine should be expanded to service area including hairdressers.
