Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossae. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present a case of fetal bilateral renal agenesis diagnosed by ultrasonography after amnioinfusion at 19 weeks gestation.

Pseudoangiomatous stromal hyperplasia (PASH) of the breast occurs in premenopausal women and is characterized by anastomosing channels lined by spindle cells. It has been suggested to be of hormonal origin. This unusual condition may also be mistaken for a vascular tumor. We analyzed eight cases of PASH of the breast in Samsung Cheil Hospital from 1992 through 1998. All patients were premenopausal and had painless breast lump. Clinical diagnoses were fibroadenomas. Grossly, the masses were well circumscribed, nonhemorrhagic and measure 2.2 to 5 cm. Histologically, they consisted of complex interanastomosing channels lined by slender spindle cells, which resembled low grade angiosarcoma. Cells that line the interanastomosing channels showed no immunoreactivity for Factor VIII and electron microscopic findings consistent with fibroblast. All patients were treated with surgical excision and none of them had recurrence for 1 to 69 months (mean: 19 months) postoperatively. Pathologic diagnosis of PASH may be difficult unless the pathologists are aware of the presence of a mass lesion and appreciate the characteristic stromal changes. PASH should be included in the differential diagnosis of a circumscribed mass, especially in the premenopausal women.

The purpose of this study was to evaluate the effects of caffeine and calcium on the activities of the osteoblastic cell from mouse calvaria. The author cultured osteoblastic cells obtained from the mouse calvaria and were divided into three groups: the caffeine-treated, the calcium-treated and the combine-treated group. In caffeine-treated group, the cell toxicity was measured by MTT assay at 1, 2 and 4 days after treatment of caffeine. In all groups, the densities of the mineralized bone nodules were measured by imaging analyzer after Von Kossa staining. The alkaline phosphotase (ALP) activities were measured at 2, 7, 14, 21 and 28 days and the interleukin-1beta activities at 48 hours after treatment of caffeine and calcium. The measurements were statistically executed with ANOVA test and the results were as follows. 1. The cellular toxicity of the caffeine increased with the concentration of caffeine during the incubation period. 2. The maximum densities of mineralization were observed at 0.2 mM caffeine-treated group, 1.2 mM calcium-treated group, 0.1 mM caffeine and 1.8 mM calcium-treated group. 3. The activities of ALP were peaked at 14 days at calcium-treated group as no-treated. But, the activities of ALP increased with concentrations of caffeine at caffeine-treated group. At combine-treated group, the act of ALP were peaked at 24 days at 1.2 mM, 1.8 mM calcium-treated group, But decreased at 2.5 mM calcium-treated group. 4. The activites of the IL-1beta were increased significantly at 0.2 mM caffeine-treated group, 1.8 mM calcium-treated group and 0.1 mM caffeine and 1.8 mM calcium-treated group. But, they were decreased at all groups of high concentration.

BACKGROUND: Neck and shoulder pain (NSP) is fairly common in adolescents, which is associated with a high prevalence of NSP found during adulthood as well; therefore, its significance during adolescence should not be underestimated. We surveyed the prevalence of recurrent NSP, lifestyle, and risk factors in Korean high school students, and examined the influence of recurrent NSP on the quality of life. METHODS: Nine hundred thirty one male students (16-19 years old) from two academic high schools in Seoul were included in this study. The survey consisted of a questionnaire to assess the prevalence of recurrent NSP, with questions regarding having an occurrence more than once a week, characteristics of NSP, activity and lifestyle of the students, and the risk factors for recurrent NSP. A 36-item Short Form questionnaire was also examined. RESULTS: We found that 44.3% of the high school students surveyed had recurrent NSP (more than once a week) and the overall prevalence of NSP was 79.1%. The average sitting time was 10.2 +/- 2.7 h/day. 59.0% did not sit straight, 14.7% used assisting devices during reading, and 11.9% answered that they stretched regularly. Found from their self assessed health, frequent fatigue and frequent depressed mood presented significant associations with the higher prevalence of recurrent NSP. CONCLUSIONS: Korean high school students had a high prevalence of recurrent NSP. Clinical attention is needed for the prevention and resolution of recurrent NSP found in high school students.

Maffucci's syndrome is a very rare, congenital and non-hereditary mesodermal dysplasia manifested by multiple enchondromas and soft tissue hemangiomas. Since Maffucci had reported this sysdrome in 1881, there have been more than 100 cases reported, and also there has been reported that Maffuddi's syndrome has various interstitial tumor. However there hasn't been any report about Maffucci's syndrome with testicular teratoma. Here we report in this paper that the patient was diagnosed as Maffucci's syndrome of enchondroma and liver hamangioma and also had testicular teratoma. He was admitted for the evaluation of gynecomatia and diagnosed as enchondroma by bone biopsy of the right rib and tibia. Liver hemangioma was also found through abdominal ultrasonogram, CT scan and liver biopsy. And the testicular teratoma was confirmed through testicular biopsy. He is finally diagnosed as Maffucci's syndrome with testicular teratoma and literatures were reviewed.

In 1947, Ota et al. first reported a case of phakomatosis pigmentovascularis and defined a subgroup of this disease having a congenital generalized hemangioma and pigmented lesions including a mongolian spot-like lesion, nevus pigmentosus and nevus of Ota. We experienced a case of phakomatosis pigmentovasularis type IIb in a 10-day old male baby, who since birth, had generalized nevus flammeus and blue spots, syndactyly between 2nd and 3rd toes in both feet, and dilated collecting system in left kidney.

PURPOSE: We investigated the correlations between the expression of claudin-1 and claudin-7 in clear cell renal cell carcinoma (clear cell RCC) and clinical parameters. MATERIALS AND METHODS: The subjects of this study were 119 patients with confirmed clear cell RCC between January 2000 and December 2007. Their RCC tissues were immunohistochemically stained for claudin-1 and claudin-7. The correlations between the expression of claudin and parameters such as sex, age, body mass index (BMI), tumor size, TNM stage, Furhman nuclear grade, postoperative distant metastasis, and cancer-specific survival were analyzed. RESULTS: Among the total 119 subjects, claudin-1 was expressed in 18 (15.1%) and claudin- 7 in 31 (26.1%). Claudin-1 was expressed in patients who were older (p=0.007), who had a greater tumor size (p=0.001), who had a higher pathologic T stage (p=0.009), who had preoperative distant metastasis (p=0.035), and who had a higher Furhman nuclear grade (p=0.004). Claudin-7 was expressed only in patients who had a higher Furhman nuclear grade (p=0.031). The risk of postoperative distant metastasis was associated with the expression of claudin-1 (p<0.001) but not with the expression of claudin-7 (p=0.668). The expression of claudin-1 and -7 was not associated with cancer-specific survival (p>0.05). CONCLUSIONS: In clear cell RCC, claudin-1 was expressed in patients who were older and who had a greater tumor size, who had higher T or M stages, and who had a higher Furhman nuclear grade. The expression of claudin-1 was associated with a higher risk of postoperative distant metastasis.

INTRODUTION: The gamma-aminobutyric acid type A (GABAA) receptor is an important pharmacological target of alcohol. The phamacological characteristics of the receptor are largely determined by its subunit composition. Compared with all other alpha subtypes, the alpha6- containing receptors are more sensitive to GABA and less sensitive to benzodiazepines. The purpose of this study was to address a role for GABAAalpha6 receptor subunit gene in the development of alcohol dependence. The differential manifestation of alcohol withdrawal symptoms related to GABAAalpha6 polymorphism in patients treating with benzodiazepines was also examined. METHODS: Eighty-seven inpatients with alcohol dependence, and sixty healthy controls were evaluated using CIWA-Ar scale. Each patient was genotyped for GABAAalpha6 subunit. Association between GABAAalpha6 polymorphism and severity of withdrawal symptom were determined. RESULTS: No significant difference was found in GABAAalpha6 receptor genetic type and allelic distribution between the alcohol dependent and control subject. Tremor was more severe in CC than TT type. TT type had higher degree of anxiety, agitation and headache than CC type. The GABAAalpha6 C allele increased the average score of tremor significantly, and T allele increased that of agitation. CONCLUSION: The results suggested that GABAAalpha6 genetic polymorphism was not associated with alcohol dependence and with severity of alcohol withdrawal symptoms. But in benzodiazepine treated patients, GABAAalpha6 polymorphism and allelic type show the difference in severity of each withdrawal symptom. These differences of severity are partly responsible for the unique pharmacological properties associated with the GABAAalpha6 subunit.
