Background: In recent years the sex ratio at birth in Viet Nam is imbalanced, with the number of male births being higher than that of female births. Objectives: To describe the trend and distribution of sex ratio at birth by time and geography, and investigate the relationship between sex ratio at birth and abortion ratio in 2006. Subjects and method: The study was conducted in 3.840 communal health stations, 723 district hospitals/polyclinics and 132 provincial and central hospitals with total of 1,095,064 births, occupied 78% of births over the nation in 2006. Result: The male/female sex ratio varies between areas, with the ratio being higher in rural than in urban and higher in the North \u2013East and North-Central regions than in the rest of country (p<0.05). Conclusion: There has been the clear imbalance of sex ratio at birth since 2002 (varying from 110 to 113), as well as the significant imbalance of sex ratio at birth by provinces. High imbalance of sex ratio at birth is related to the high abortion rate in these provinces. Viet Nam needs to implement strong measures/actions to avoid the same situation as in China and India.

Total 48 cases of the patients of neonatal tetanus, who were admitted and evaluated in our pedi dept from JAN. 1970 to Dec. 1975 and from Jan to Dec. 1979, are summerized with following result. 1) The number of patients yearly means were about 6~7 cases and the over all motality was 48.4%. 2) The sex ratio was 2:1(male: female). 3) Home delivary without sanitory facilities was most common(90%), but 3 cases was delivered at hospital. 4) The most of umbilical cords were cutted by unsterilized scissors(77.5%). 5) The most common symptoms on admission were poor feeding(97.7%), convulsion(93.8%), and trismus(91.7%). 6) The mean of incubation period was 7 days and the longer the incubation period was, the better the prognosis was. 7) The higher the temperature was, the worse the prognosis was. 8) The most of patients were admitted within one day and the earlier admitted cases were, the poorer the condition of baby was. 9) The most of hospital stay in expired cases was about 1~2days. 10) The peripheral blood finding on admission revealed leukocytosis(78%).

It is known that pediatric inguinal hernia is caused by the incomplete closure of processus vaginalis (PV). In the case of unilateral hernia, possibile contralateral patent PV should be considered because of its delayed appearance as well as its risk of incarceration. Direct visualization of patent PV could be done by contralateral exploration or by indirect exploration through the ipsilateral opening site of the affected hernia assisted with laparoscope. A patient group (321 persons) to whom laparoscopy was not performed from March 2000 to March 2003 was analyzed and compared with a patient group (280 persons) to whom laparoscopy was performed from April 2003 to September 2005. With all 601 patients, the sex ratio (male/female) of patients was 3.8:1. The side distribution was 57.7% in the right, 32.1% in the left and 10.1% in bilateral. There was no difference of sex and side distribution between before and after laparosopy adoption. We did not find an age correlation in natural closure of the residual PV of the peritoneum. Contralateral hernia developed in 14 persons (2.5%) after the operation of unilateral inguinal hernia before laparoscope adoption. But no contralateral hernia developed after April 2003 with laparoscopy. We think that if we use laparoscopy, being a safe and accurate method, to check whether the contralateral residual PV is opened or closed, possible future contralateral operation can be avoided.

During the four-year period from 1954 to 1958, a roentgenological and morphological study of the paranasal sinuses in Koreans, especially of the frontal and maxillary sinuses, was made. In these studies, postero-anterior and lateral radiograph, life-size, of the normal frontal and maxillary sinuses were measured to obtain standard values for the Korean peop1e, together with their sex ratio, age distribution, and septal features of the sinuses.

PURPOSE: We aimed to identify the need for an adjunctive internal sphincterotomy based on an evaluation of the changes in the symptoms and manometric results after a hemorrhoidectomy for hemorrhoids with difficulty in evacuation. METHODS: Twenty-five (25) patients who had hemorrhoids with difficulty in evacuation and 13 patients who had hemorrhoids without difficulty in evacuation were prospectively evaluated. Patients were interviewed about symptoms and underwent anorectal manometry before and 2 months after surgery. Difficulty in evacuation is defined as the difficulty that a patient has when trying to evacuate the rectum. RESULTS: There were significant differences in the sex ratio, the frequency of bowel movements, and the duration of bowel movements between the two groups (P<0.05). In cases with difficulty in evacuation, the frequency of bowel movements was significantly higher postoperatively and the duration of bowel movements was significantly shorter (P<0.05). The symptom of difficulty in evacuation disappeared in 21 of the as patients experiencing such a symptom, and was improved in the remaining of patients (P<0.05). Following the hemorrhoidectomy for the patients with difficulty in evacuation in the mean and the maximum resting pressure, and the maximum squeeze pressure decreased significantly (P<0.05). CONCLUSIONS: An adjunctive internal sphincterotomy was not necessary for patients who had hemorrhoids with difficulty in evacuation because following the hemorrhoidectomy, the resting pressure was significantly decreased, and the difficulty in evacuation had nearly subsided.

From January 1990 to January 1996, we analyzed outcome according to the distribution of aneurysms, the type of surgical treatment, the timing of operation, and the patient's pre-operative status in a total of 54 cases of multiple intracranial aneurysms. The frequency of multiple intracranial aneurysms was 13.4% and the sex ratio was 1:2 with female being predominant. The frequency of aneurismal location was MCA(35.0%), P-comm. Artery(25.0%) and A-comm. Artery(15.0%) in that order. The number of ruptured aneurysms was in the order to MCA aneurysms. A-comm aneurysms, and P-comm aneurysms. The size of ruptured aneurysms was 6-10mm in 34 cases(64.2%). The unilateral distribution of aneurysms was 31 cases(57.4%) and the bilateral was 28 cases(42.6%). Depending on how many times the patient had the operation, these were 29(57.4%) cases of complete single operation, 17 cases(31.5%) of complete two-stage operation, and 8 cases(14.8%) of partial operation. Surgical outcome was good(GOS< or =4) in 42 cases(77.8%), and six patients(11.1%) expired. Based on the results of the above study we have concluded that initial Hunt-Hess grade has a close relationship with the outcome, but the operation type, the timing of operation, the number and distribution of aneurysms do not significantly effect the outcome.

PURPOSE: This study aimed to find out the difference in between the anatomic properties children with intermittent exotropia and children with orthophoria. METHODS: The intermittent exotropia group consisted of 35 patients who had an angle of deviation of more than 15 prisms. The control group consisted of 35 orthophoric children with comparable age and sex ratio. From the view of skull AP, we compared the diameter, interlateral wall distance, and intermedial wall distance of the orbital rim. Also we compared the intercanthal distance, interlateral canthal distance of eyelids, and interpupillary distance. RESULTS: The average values of interpupillary distance, intercanthal distance, and interlateral canthal distance of exotropic group were 54.23+/-1.85 mm, 34.75+/-1.66 mm, and 78.25+/-4.21 mm, respectively. Compared to those of control group, which were 53.59+/-1.21 mm, 33.56+/-1.54 mm, and 76.68+/-3.23 mm, respectively, there was no significant difference (P>0.05). The average values of the diameter, interlateral wall distance and the intermedial wall distance of the orbital rim were not significantly different between two groups (p>0.05). CONCLUSIONS: Our results showed that the anatomic properties including orbital rim size and orbital exodeviation did not seen to influence the development of intermittent exotropia.
