Scimitar syndrome (SS) is a rare congenital anomaly characterized by hypoplasia of the right lung and partially anomalous pulmonary venous drainage to the inferior vena cava. The term scimitar derives from the shadow created by the anomalous pulmonary vein on chest X-ray that closely resembles that of a curved Turkish sword. It rarely presents as an isolated abnormality. Various cardiac and non-cardiac anomalies have been association with SS, such as right lung hypoplasia, dextroposition of the heart, hypoplasia of the right pulmonary artery, systemic arterial blood supply to the right lower lung from the infra-diaphragmatic aorta, and a secundum type of atrial septal defect. However, an imperforate anus has not been reported previously in association with SS. We describe the first case of infantile scimitar syndrome accompanied with an imperforate anus in a newborn who presented with tachypnea and right pulmonary atelectasis.

To study the possibility of attraction magnetic forces to expand maxillary arch, we used 2 big adult dogs, 2 small puppies, 1 small adult dog as experiments, and 1 small adult dog as a control. We measured the intercanine width and intermolar width and histologically observed in the suture and cervical and apex region of teeth and took occlusal X-rays to observe separation of suture line in the maxilla. The results were as follows: 1. Expansion velocities of intercanine (0.25mm/day) and intermolar widths (0.23mm/day) in puppies were faster than those (0.135mm/day, 0.09mm/day) in adults. 2. In all experiments in adults (0.135mm/day) and puppies (0.25mm/day), expansion velocity of intercanine widths were faster than those (0.09mm/day, 0.23mm/day) of intermolar width. 3. In all experiments ectatic changes were observed and cellularities of fibroblast increased in the suture line. Only in adults dogs the separations of palatal suture were observed in the occlusal X-ray view. 4. In the puppies bony deposition was particularly observed in the suture line and micro-bony fragments were often observed. 5. In the all experiments no root resorption was observed in the cervical and root area, but normal root resorption due to eruption of permanent teeth was observed in the puppies.

Multiple primary cancer is relatively rare disease. But its study revealed a aspect of carcinogenesis and has changed our concept in second primary cancer. It is not a metastasis or recurrent cancer. Multiple primary cancer associated with gastric cancer is most common in Korea. Now we report two cases of multiple primary cancer in esophagus and stomach, successfully treated.

BACKGROUND: Tuberculosis is the most frequent opportunistic infection in HIV-infected patients in Korea. We examined the incidence and risk factors for tuberculosis in HIV-infected patients. METHODS: We reviewed the medical records of 143 HIV-infected patients between January 1988 and June 1997 at the Seoul National University Hospita The incidence of tuberculosis was determined by the number of new tuberculosis per 100 patients divided by a total duration of follow-up (cases/100 person- years). The incidence of tuberculosis was analyzed with respect to CD4+ lymphocyte count, status of tuberculin skin reaction, and status of delayed hypersensitivity skin reaction. RESULTS: The total duration of follow-up was 229.6 person-years. During follow-up, 22 patients developed tuberculosis [9.6 cases per 100 person-years (95% CI, 6.0 to 14.5)]. The incidence of tuberculosis according to sex and transmission route showed no significant difference. Tuberculosis occurred more frequently in patients with minimum CD4+ T lympho-cyte counts of less than 200 cells/mm3 (14.2 cases/100 person-years) than in those with higher T lymphocyte counts (3.9 cases/100 person-years) [relative risk, 4.02 (95% CI 1.32 to 12.5), P=0.009]. The incidence of tuberculosis was higher among tuberculin- positive patients [17.0 cases/100 person-years (95% CI, 9.0 to 29.0)] than among tuberculin-negative [8.0 cases/100 person-years (95% CI, 3.2 to 16.6)], but the difference was not statistically significant [relative risk, 2.35 (95% CI, 0.88 to 6.26, P=0.078)]. The rate of tuberculosis in patients with negative delayed hypersensitivity test was not significantly different from that in patients with positive results (P=0.510). CONCLUSION: The incidence of tuberculosis was 9.6 cases per 100 person-years. CD4+ lymphocyte count (<200 cells/mm3) was the most useful predictor for the development of tuberculosis in HIV patients in Korea.
