Cystic Lymphangioma of the Adrenal Gland: Report of a Case / 대한비뇨기과학회지

Cystic lymphangiomas are uncommon benign tumor due to the lack of adequate drainage from the sequestrated lymphatic vessels to the venous system because of insufficiency or atresia of the efferent channels. They occur mostly in children and predilection sites are the neck and axilla. Treatment is complete surgical excision. Unless completely removed, recurrences are common. We report a case of cystic lymphangioma of adrenal gland in a 45-year-old woman with right flank pain. Adrenalectomy was performed and the mass consisted of three well demarcated cysts.

The Study of Expression of Proliferating Cell Nuclear Antigen(PCNA) and Nucleolar Organizer Regions(NORs) in Transitional Cell Carcinoma of the Urinary Bladder / 대한비뇨기과학회지

The expression of two cell proliferation indices, the proliferating cell nuclear antigen( PCNA), using the monoclonal antibody in the immunoperoxidase method, and the nucleolar organizer regions (NORs), using silver nitrate staining technique, were assessed in formalin-fixed paraffin embedded material of transitional cell urinary bladder carcinomas. The aim of our study was to examine comparatively the expression of PCNA and the number of NORs in 37 transitional cell bladder carcinomas and to investigate how they correlate with tumor grade and the disease stage. It was noticed that the PCNA expression rate(%) related to grade was statistically significant only between grades II and III (p 0.05). The mean number of AgNORs per nucleus between grades I and II and between grades II and III were statistically significant(p<0.05). As far as the correlation of PCNA expression rate(%) with the stage is concerned, PCNA expression rate (%) was higher in the invasive tumors(p<0.05) than in the superficial tumors and AgNOR Numbers was also greater in the invasive tumors(p <0.05). The linear correlation coefficient between PCNA expression rate (%) and AgNOR counts was 0.52(p <0.001) In conclusion, a considerable relationship was found between the histological grade and each of the two indices used. A good correlation was also demonstrated between each of PCNA expression rate(%) and AgNOR scores to the pathologic stage. Our results suggest that PCNA expressionrate( % ) and AgNOR scores may be prognostic induces in urinary bladder cancer.

Diagnosis of Urinary Tract Tuberculosis Using Polymerase Chain Reaction(PCR) / 대한비뇨기과학회지

Recent development in the polymerase chain reaction( PCR) technology has brought an extraordinary opportunity for the rapid detection of Mycobacterium tuberculosis in clinical specimens for the diagnosis of tuberculosis. This study was initiated to compare the PCR results with those obtained by culture on Ogawa medium. A total of 18 urine samples from patients suspected having tuberculosis were tested by PCR using the primer: P1(5'-AGC-ACG-GCG-ATT-TGG-AGT-CG-3')andP2 (5'-ATC-GTT-TTC-GGC-GGT-ATC-TG-3'). Of 5 culture positive samples, 3 showed the 320 bp DNA products in PCR and 2 were negative. Besides, 3 of 13 culture negative samples also showed positive results in PCR. In conclusion, the PCR easily detected M.tuberculosis in smear-positive samples. The PCR could detect the presence of M.tuberculosis when the samples were culture negative. Therefore, the PCR was probably more sensitive than culture. Because of the extreme sensitivity of PCR, one would expect to be able to detect organism that are present in low numbers and those that are nonviable. However, the PCR method could miss the culture proved M.tuberculosis. The PCR method looks promising for the rapid and specific laboratory diagnosis of tuberculosis.
