ABSTRACT
Primary empty sella syndrome is a phenomenon caused by cerebrospinal fluid filling resulting from the herniation of the subarachnoid space within the sella. The pituitary function of primary empty sella syndrome is usually normal. But sometimes this syndrome causes some degree of pituitary dysfunction associated with hypersecretion or deficiency of pituitary hormone. Central diabetes insipidus with primary empty sella syndrome is rarely reported. Furthermore, most of those cases are accompanied by other pituitary dysfunction. We report here on a 35-year-old female who suffered from polyuria, polydipsia since childhood. She was diagnosed with central diabetes insipidus with primary empty sella syndrome. She had no anterior pituitary dysfunction except mild hyperprolactinemia.

BACKGROUND: Cardiovascular disease is the main cause of mortality in dialysis patients. Carotid intima-media thickness (CIMT) is used as a surrogate marker of early atherosclerosis. Atherosclerosis can cause vascular access failure.The purpose of this study was to define the clinical features of atherosclerosis in hemodialysis patients based on CIMT and to define the relationship between CIMT and access failure. METHODS: In this cross-sectional study, the CIMT of 60 patients on hemodialysis was examined using B-mode Doppler ultrasonography between May 2012 and November 2012. Carotid atherosclerosis was defined as a CIMT> or =0.9 mm or the incidence of atherosclerotic plaques. RESULTS: The patients' mean age was 54.5+/-10.6 years, and 60% of the patients were male. The CIMT was 0.81+/-0.47 mm (range, 0.35-2.50 mm).The group with atherosclerosis was characterized by older age compared with those without atherosclerosis. Patients with atherosclerosis showed much shorter durations of access patency than their counterparts in the nonatherosclerosis group (hazard ratio, 2.822; 95% confidence interval, 1.113-7.156; P=0.029). Moreover, being overweight was associated with a 2.47-fold (95% confidence interval,1.101-5.548) increased primary access failure. CONCLUSION: This study shows that atherosclerosis is associated with older age. Patients who are overweight and have atherosclerosis may have shortened access patency.

Pulmonary sclerosing hemangioma is a relatively rare neoplasm of the lung with polymorphic histologic features of 2 unifying cellular components including surface cuboidal cells and interstitial round cells. Pulmonary sclerosing hemangioma typically occurs in middle aged women with asymptomatic, peripheral, solitary, well-circumscribed lesions. Although it is pathologically benign, it reveals size growing and chest symptom. We here report a case of pulmonary sclerosing hemangioma in a 72-year-old woman. She presented chest discomfort. A chest radiography and a chest computed tomography scan showed growing size from 3.2x3.1 cm to 6.0x5.3 cm in left upper lung during 10 years' follow-up period. Surgical resection of lung revealed a distinct constellation of findings including 2 epithelial cell types, surface cells, and round cells, which form 4 architectural patterns, papillary, sclerotic, solid, and hemorrhagic. She was diagnosed as pulmonary sclerosing hemangioma and chest discomfort disappeared.

A multi-locus probe. called pHK-450. detecting multiple variable DNA fragments, was constructed by cloning of the 450 bp fragments into pCR(TM) vector, which could be obtained from amplification of the variable region of the D8S210 locus of human genome with a primer set of UF1. UR1, and UR2. The sequence data shows that the variable region is entirely G-C rich on one strand consisting of tetranucleotide repeat unit (GGAA)n at both margins and internally diversed regions with simple irregular repeat units of GGAA, GGAG, or GGGAA. The genetic complexixty of the resulting individual-specific DNA patterns was investigated by studying a Korean pedigree(both parents and 10 children). HaeIII and HinfI-generated DNA fragments are inherited to their children in a Mendelian manner with segregation ratio of 1:1.05 and 1:1.14. respectively. In the HinfI-digested genomic DNAs, the segregation of up to 25 variable DNA fragments from both parents could be analysed in a single sibship. Most of these variable DNA fragments detected by pHK-450 probe are not paired as allele, which suggests that they may be derived from 23 heterozygous loci. In the HaeIII-digested genomic DNA, 26 variable DNA fragments are segregated from both parents to 10 children. Excluding one allelic and three linked DNA fragments, 22 out of 26 scored DNA fragments may be derived from 23 hetrozygous loci. To determine the variability of DNA fragments, DNA samples from 113 unrelated Korean were digested with HinfI and hybridized using pHK-450 probe. Pairwise comparisons of individual variable DNA fragments show that the polymorphic patterns were highly specific to an individual. The mean probaility(X) that fragments in A individual is present in B individual is 0.0337. From the degree of maxiaml sharing, band approximate estimates of mean allele frequency and homozygosity is calculated being 0.187 and the mean heterozygossity is 89.69%. For pHK-450 probe, the probability that all 10 resolved DNA fragments in the 5-30 kb size range in an individual A are also present in a second unrelated individual B is (0.337)(10) or 7.1 X 10(-6).The above results suggest that the Muiti-locus probe, pHK-450, is suitable for rapid polymorphic marker generation and can be applied to individual identification in forensic medicine

Mucocele of the appendix is uncomrnon and rarely diagnosed preoperatively. The malignant rountpart-i.e. mucinous cystadenocarcinoma--has the same grross appearance and many micro scopic features in cornmon wilhe the benign form. It rnay be associated with ovarian mucinous cystadenoma of strikingly similar microscopic appearence. A serious complication is a rupture of the mucoeele resulting in pseudomyxoma peritonei. Each case of benign and malignant mucocelr of the appendix falsely diagnosecl as an oovarian tumor before laparotxumy are presented wilh a brief rieview of the literatures.
