Pseudohypoaldosteronism (PHA) is rare herediary salt wasting syndrome due to peripheral resistance to aldostrone. PHA type I, subdivided into isolated renal insensitivity to aldosterone of autosomal dominant inheritance and multiple target organ defect of autosomal recessive inheritance, and PHA type II show similar clinical manifestations except hypertension which is limited to type II. PHA type I is charaterized by hyponatremia, hyperkalemia, high plasma aldosterone and renin activity. Variable degrees, completely asymptomatic to severe fatal, of salt loosing manifestationsdehydration, hypotension, failure to thrive, and renal tubular acidosis usually start during infancy. Sodium loss not only from kidney but also from sweat gland, salivary gland and colon may occur in some cases. Recently we experienced two cases of PHA, a 27 days of age male newborn infant with charateristic clinical symptoms and typical laboratory manifestations of PHA, confirm diagnosed as PHA type I of isolated renal defect by pilocarpin iontophoresis showing normal sodium concentration in sweat gland, and his asymptomatic 6 year-old brother with the history of salt loosing symptoms treated until second year of life diagnosed as PHA type I by markedly elevated plasma aldosterone and renin activity. Brief review and related literatures were also presented.

The authors retrospectively analysed the ultrasonographic findings of 43 cases of surgically confirmed hypertrophic pyloric stenosis and their postoperative findings of sonograms taken at 1 month(n=40) or 3 months( n=5) after pyloromyotomy. In preoperative study, the thickened pyloric muscle was isoechoic or slight hypoechoic relative to liver on the midline longitudinal view and appeared as a "nonuniform acoustic ring" on the transverse view. The results of measurement in the all cases with hypertrophic pyloric stenosis were the pyloric thickness ≥3.8mm, the pyloric diameter ≥14mm, the pyloric channel length ≥16mm, the pyloric muscle volume ≥2.21Cm

PURPOSE: An anorectal melanoma (AM) is a very rare tumor. However, sufficient data supporting effective surgical options for the disease do not exist. This retrospective review aimed to analyze treatment outcomes for an AM. METHODS: From June 1999 to December 2008, we retrospectively reviewed a prospectively collected consecutive series of 19 patients who had undergone a surgical resection for an AM at a single institute. Surgical method and clinicopathological factors were analyzed. RESULTS: The median age was 61.4 years (range, 46 to79 years). Main symptoms were an anal mass, hematochezia, perianal pain, tenesmus, fecal incontinence, and bowel habit change. The average duration of symptoms before diagnosis was 7.8 months (range, 1 to 36 months). S-100 and HMB-45 were positive in all patients, even in non-melanin pigmentation. There were 12 abdominoperineal resections (APRs) and 7 wide local excisions (WEs). The APR showed longer overall survival when compared with the WE (64.1 months vs. 10.9 months, P < 0.001). No patients who underwent a WE survived more than 13 months. CONCLUSION: A high index of suspicion is necessary to establish the diagnosis for an AM in patients with anal symptoms, and S-100 and HMB-45 can be useful markers for an AM. Even with the small number of cases and the short follow-up, our data suggest that an APR for an AM may provide longer survival than a WE.

Gastric volvulus is a rare condition, and it is classified as the organoaxial or mesentericaxial type according to the axis of rotation. We experienced 1 case of pediatric recurrent mesenteroaxial gastric volvulus and we report here the ultrasonographic and CT findings.

OBJECTIVE: The aim of this study was to analyze a relation between the recurrence of cervical intraepithelial neoplasia (CIN) and the detection of high-risk human papillomavirus (HPV) DNA after loop electrosurgical excision procedure (LEEP), and to evaluate the clinical efficacy of HPV DNA test by Hybrid Capture Assay as a predictor of the recurrence of CIN after LEEP. METHODS: From January 2000 through March 2003, the charts of 238 women diagnosed as CIN and treated with LEEP were reviewed retrospectively. HPV DNA test (Hybrid Capture System I) for high-risk HPV was performed in all patients before LEEP. They were followed up with Papanicolaou smears and HPV DNA tests at the interval of 3 months during the first 6 months and then at the interval of 6 months. The Chi-square test was used for the statistical analysis. RESULTS: The rate of detection of high-risk HPV declined chronologically after LEEP. A higher recurrence rate was noted in the HPV DNA positive group after LEEP, comparing with the negative group, at 3 months (54.5% in positive vs. 6.5% in negative; p<0.05), at 6 months (61.1% in positive vs. 5.4% in negative; p<0.05), at 12 months (50.0% in positive vs. 14.0% in negative; p<0.05), and at 18 months (50.0% in positive vs. 15.2% in negative; p<0.05). The negative predictive value was high at 3 months (93.5%), at 6 months (94.6%), at 12 months (86.0%), and at 18 months (84.6%). There were significant associations between the recurrence of CIN and positive resection margin except for glandular involvements. CONCLUSION: The detection of high-risk HPV is a risk factor for the presence of CIN after LEEP. HPV DNA test by Hybrid Capture Assay after LEEP may be useful marker for the negative prediction of recurrence of CIN after LEEP.

Gastric web is a rare gastric anomaly and almost all the reported cases have been located in the distal antrum. We experienced a case of neonatal gastric web that was located in the body of stomach, and we report the findings of the upper gastrointestinal series and ultrasonography.

PURPOSE: CTAP(CT during arterial portography) has been shown to be the most sensitive technique available for the detection of hepatic mass. But because of many false positive lesions, it is important to interpretate the findings correctly. So we tried to analyse the false positive findings in CTAP. MATERIALS AND METHODS: Materials were 47 patients that had (;TAP for the detection of hepatic lesions. After performing superior roesenteric artery (SMA) arterial portography for the detection of vascular variation, CT^P was done. 100 to 150 cc of 50% diluted nonionic contrast media was injected at 2--3ml/sec rate. Spiral CT was used with 8mm slice thickness and 8mm/sec table speed. We compared the findings of CTAP with CTHA(CT during hepatic arteriography), enhanced (;T, anglogram, US, Lipiodol CT and biopsy. RESULTS: Twenty nine false positive lesions were found. There were 11 peritumoral defects, 7 straight line signs, 5 perihilar defects, 2 periligamentous defects, 3 subcapsular defects and 1 defect by cirrhosis. CONCLUSION: When CTAP is used for the evaluation of hepatic lesion(esp, preoperative evaluation), understanding of the false positive findings and the characterization of the lesion through multi-modality approaches are needed for the correct diagnosis and the proper treatment.

BACKGROUND: Patients with obstructive sleep apnea syndrome (OSAS) have some deficits in attention and frontal functions. The pathophysiology of the cognitive dysfunction is still controversial. We investigated the cognitive performances of OSAS patients, and the relationship of cognitive functioning and nocturnal respiratory findings and daytime sleepiness. METHODS: Neuropsychological testing, the Beck Depression Inventory and the Epworth sleepiness scale (ESS) were administered to 35 patients with OSAS and to 31 normal controls. RESULTS: Compared to the controls, OSAS patients had significant impairment on the Korean mini mental state examination (K-MMSE), semantic and phonemic fluency, the time and number of correct on the Korean Stroop color word test, the Digit cancellation test and delayed response on the Seoul verbal learning test (SVLT). ESS was significantly correlated with K-MMSE, trail making A, the time and number of correct on the Korean Stroop color word test, delayed recall of SVLT and Rey figure test and number of fulfilled categories on the Wisconsin card sorting test in OSAS patients. The Apnea-hypopnea index (AHI) was significantly correlated with the copy of the Rey figure test. Arousal index, total time slept with oxygen saturation below 90% and the lowest oxygen saturation were not correlated with any neuropsychological parameters. CONCLUSIONS: Patients with OSAS have cognitive impairment concerning attention, executive function and retrieval of memory. The cognitive impairment may be attributed not to nocturnal hypoxemia, but to subjective daytime sleepiness.
