Dyskeratosis congenita is a rare genodermatosis of ectodermal dysplasia, which is characterized by the diagnostic triad consisting of reticulated hyperpigmentation, dystrophic nails, and leukoplakia. There is a predisposition to malignancy, particularly at sites of leukoplakia. Bone marrow failure can occur in about a half of the cases. A 16-year-old boy was presented with asymptomatic reticulated pigmentation of the neck and nail dystrophy. The patient also had leukoplakia on the tongue, nasolacrimal duct obstruction and cataract. The histopathological findings taken from the reticulated lesion were consistent with poikiloderma atrophicans vasculare. These clinical and histopathological findings were typical features of dyskeratosis congenita.

The present study was undertaken in an attempt to establish the range of normal blood pressure levels in Koreans. A representative group of the working population, consisting of 39,859 persons (23,834 men and 16,025 women) who were able to work regularly on daily duty and who lived in various parts of the country, was studied, using casual blood pressure readings. The arithmetic mean, the standard deviation and the frequency distribution of the blood pressure readings were determined for each sex and for each age group from five to seventy nine years of age. The normal range was assumed to include the 80% of all the readings which were within 40% of either side of the mean. Any blood pressure which the mean was considered to be abnormal. The readings falling between these two limits were regarded as borderline. The limits of normal blood pressure, as determined by this method, were found definitely to vary with age and sex. The effect of body weight on the blood pressure was investigated. It was found that the systolic and diastolic blood pressure were progressively increased with the increase in body weight regardless of sex and age. The incidence of systolic hypertension was 6.0% in adult males and 6.2% in females, diastolic hypertension occurred 6.8% in males and 5.8% in females. The incidence of hypotension, below 90 mmHg. systolic, was 0.6% in males and 1.7% in females, and below 60 mmHg. diastolic was 6.6% in males and 9.1% in females. A Comparison of the mean blood pressure was made between the rural and the urban population of Koreans. The mean blood pressure readings in the urban population are higher than those in the rural population, both in systolic and diastolic blood pressures and in all age groups. A comparison of the mean blood pressure also was made between Koreans and Americans, Chinese, Japanese, Filippinos and Indians. The systolic and diastolic blood pressure in Americans (U.S.A.) is higher than that in Koreans. Those in the Japanese and Chinese are similar until the age of fifty, from the age of fifty, the pressures are higher than those in Koreans. The blood pressure of Filippinos is similar to the blood pressure of Koreans all through the age groups. In Indians, pressures are lower than in Koreans.

BACKGROUND: Patent ductus arteriosus (PDA) ligation is usually performed by congenital cardiac surgeons. However, due to the uneven distribution of congenital cardiac surgeons in South Korea, many institutions depend solely on adult cardiac surgeons for congenital cardiac diseases. We report the outcomes of PDA ligations performed by adult cardiac surgeons at our institution. METHODS: The electronic medical records of 852 neonates at Chung-Ang University Hospital, Seoul, South Korea from November 2010 to May 2014 were reviewed to identify patients with PDA. RESULTS: Of the 111 neonates with a diagnosis of PDA, 26 (23%) underwent PDA ligation. PDAs were ligated within 28 days of birth (mean, 14.5±7.8 days), and the mean gestational age of these patients was 30.3±4.6 weeks (range, 26 to 40 weeks) with a mean birth weight of 1,292.5±703.5 g (range, 480 to 3,020 g). No residual shunts through the PDA were found on postoperative echocardiography. There was 1 case of 30-day mortality (3.8%) due to pneumonia, and 6 cases of in-hospital mortality (23.1%) after 30 days, which is comparable to results from other centers with congenital cardiac surgery programs. CONCLUSION: Although our outcomes may not be generalizable to all hospital settings without a congenital cardiac surgery program, in select centers, PDA ligations can be performed safely by adult cardiac surgeons if no congenital cardiac surgery program is available.

Scar endometriosis is one of the rare conditions among the extrapelvic endometriosis, but it often occurs after pelvic operation and episiotomy. Four cases of scar endometriosis following Cesarean section and episiotomy were exp- erienced and treated with complete surgical excision. Therefore we reported these cases with concerned literatures.

A 26-yr-old male patient reported worsened dyspnea, dizziness one year after an emergency Bentall operation for type A aortic dissection. There was evidence of hemolytic anemia and aortogram revealed a significant stenosis at the distal anastomosis site. During the reoperation, we found the inner felt at the distal anastomosis was inverted causing a significant stenosis. The reoperation successfully resolved this problem. Here, we report a rare case of hemolytic anemia caused by an inverted inner felt after Bentall operation.

PURPOSE: To implant tissue chips in New Zealand rabbits, and thus redurce the frequency with which scattered VX2 carcinoma nodules and early metastasis develop in these animals. MATERIALS AND METHODS: VX2-carcinoma tissue chips of two different sizes were implanted under ultrasonographic guidance. In each of 12 New Zealand rabbits (group 1), there 1-mm tissue chips were implanted in the liver using an 18-gauge needle, and in the same way, one 3-mm chip with an added gelfoam pellet was implanted in the proximal lumen of the liver of each of ten other New Zealand rabbits (group 2). Three weeks after implantation, the animals underwent dvalphase CT scanning and were sacrificed, and the Number and size of tumor nodules, and metastasis were evaluated either macro-or microscopically. RESULTS: In ten rabbits in group I, a total of 21 nodules (16 in the liver, 5 in the peritoneal wall) were observed, which in nine rabbits in group 2, a total of ten nodules-all in the liver-were present. CT scans depicted tumor nodules in 50% of group-I rabbits, and in 29% those in group 2. Mean tumor diameter was 12 +/-9 mm in group 1 and 6.4 +/-3 mm in group 2. Histologic examination indicated the presence of nodular VX2 carcinoma, with varying degrees of central necrosis, a feature more prominent in group 2. CONCLUSION: To provide a well-localized tumor nodule in rabbit liver, tissue chip implantation of VX2 carcinoma, especially with added gelfoam, is a good alternative to intraparenchymal injection of tumor suspension.

Legalized gambling is a growing industry, and is probably a factor in the presently increasing prevalence of pathological gambling. We present a case of a 36-year-old pathological gambler who was treated with fluvoxamine, a selective serotonin reuptake inhibitor, and who was assessed by functional MRI before and after drug administration. During activation periods, the pathological gambler was shown cards as stimuli, and fMRI results in several brain regions showed differential effects before and after medication and a maintenance period. This case demonstrates that the treatment response to fluvoxamine in a pathological gambler was observed not only by subjective self-report, but also by objective fMRI results. Therefore, fMRI may be a useful tool in the diagnosis and prediction of treatment response in patients afflicted with pathological gambling.

We evaluated the biological scaffold properties of canine small intestinal submucosa (SIS) compared to a those of polypropylene mesh in growing rats with full-thickness abdominal defects. SIS is used to repair musculoskeletal tissue while promoting cell migration and supporting tissue regeneration. Polypropylene mesh is a non-resorbable synthetic material that can endure mechanical tension. Canine SIS was obtained from donor German shepherds, and its porous collagen fiber structure was identified using scanning electron microscopy (SEM). A 2.50-cm2 section of canine SIS (SIS group) or mesh (mesh group) was implanted in Sprague-Dawley rats. At 1, 2, 4, 12, and 24 weeks after surgery, the implants were histopathologically examined and tensile load was tested. One month after surgery, CD68+ macrophage numbers in the SIS group were increased, but the number of CD8+ T cells in this group declined more rapidly than that in rats treated with the mesh. In the SIS group, few adhesions and well-developed autologous abdominal muscle infiltration into the SIS collagen fibers were observed. No significant differences in the tensile load test results were found between the SIS and mesh groups at 24 weeks. Canine SIS may therefore be a suitable replacement for artificial biological scaffolds in small animals.
