Hemophilia A is a severe bleeding disorder resulting from the lack of functional blood coagulation factor VIII. Accordingly, operations on patients with hemophilia A, except in a few cases, are performed with the administration of factor VIII. However, in those hemophilia A patients administered factor VIII inhibitor, factor VIII replacement therapy is ineffective. The treatment of hemophilic patients with factor VIII inhibitor is undertaken to utilize the hemostatic capacity of the activated forms of FVII, FIX and FX contained within prothrombin complex concentrates, which are purposely manufactured to contain Factor Eight Inhibitor Bypassing Activity (FEIBA) during surgery. Further, in the last few years, a new product, recombinant activated FVII (FVIIa, Novo-VII), which is thought to ensure hemostasis by binding, directly or in complex with tissue factor, to negatively charged phospholipids on the surface of activated platelets, has been licensed. Recently, we experienced a GB stone, with acute cholecystitis, in a fifty year old hemophilia A man treated with factor VIII inhibitor. Under medication with FEIBA and Novo-VII, a laparoscopic cholecystectomy was performed. Here, this case is reported, with a review of the literature.

PURPOSE: Oxalobacter formigenes is an intestinal flora degrading oxalate in the gut. However, microbiological detection of this organism is quite difficult. We tried to develop a simple, rapid and cost-effective PCR method for detecting Oxalobacter formigenes from fecal specimens and to determine whether O. formigenes could be detected from frozen fecal specimens as well as fresh stool. MATERIALS AND METHODS: Whole bacterial DNA was isolated directly from fresh and frozen stool samples obtained from 30 healthy volunteers known to be free from urolithiasis and from fresh stool samples obtained from 38 patients with urolithiasis. Genus specific oligonucleotide sequences corresponding to homologous regions residing in the oxc gene that encodes for oxalyl-coenzyme A decarboxylase were designed. A PCR-based assay was done in both fresh and frozen stool samples and the nucleotide sequences were analyzed to determine the details of oxc. RESULTS: PCR product of 416-bp molecular size encoding oxc gene was detected in 23 (77%) of 30 healthy volunteers and in 14 (37%) of 38 patients with urolithiasis. In healthy volunteers, the results of PCR for the fresh and the frozen stool proved identical in each subject. The nucleotide sequence analysis revealed that the sequence of the amplified product was compatible with that of oxc gene. CONCLUSIONS: O. formigenes could be identified easily and efficiently by this PCR-based detection system. Furthermore, as the PCR-based assay results in the frozen fecal samples were identical as that of fresh stool, immediate processing of the fecal samples may not be necessary to detect O. formigenes in the clinical setting.

Hydatid disease is Echinococcus granulosus infection in its larva form. It is endemic in many sheep- and cattle-raising countries throughout the world. In Korea seventeen cases have been reported but relapsed case is not. We report relapsed hydatid disease in pelvic cavity 10 years after primary surgery for Echinococcal cysts in the liver and pelvic cavity. The cysts were surgically removed and the patient was managed with postoperative adjuvant treatment with albendazole and followed with serologic test for anti-echinoccocus antibodies by ELISA.

Systemic sclerosis is a connective tissue disease involving primarily the skin and subcutaneous tissue but may involve other organ systems such as the lungs, gastrointestinal tract, and heart. Systemic sclerosis is a rare childhood disease. The age of onset for patients with systemic sclerosis has its peak between 30 and 50 years of age. Only 1 to 2% of all patients with systemic sclerosis have disease onset before the age of 10 years of age. We report a case of systemic sclerosis in a 7-year-old female who showed Raynaud's phenomenon as an initial manifestation.

PURPOSE: To examine and compare the perioperative outcomes of laparoscopic adrenalectomy (LA) and to determine its efficacy in patients with nonfunctioning adrenal adenomas (NFA) and subclinical Cushing syndrome (SCS). MATERIALS AND METHODS: We retrospectively analyzed the clinical data obtained from 79 consecutive patients who underwent LA for the treatment of either NFA (n=35) or SCS (n=44) between 2011 and 2016. All patients had undergone computed tomography, as well as endocrinological tests to confirm the diagnosis prior to the adrenalectomy. The primary endpoint was improved metabolic parameters relating to diabetes, hypertension, dyslipidemia, and obesity. RESULTS: Patients with SCS compared to those with NFA showed a higher occurrence of diabetes (29.5% vs. 11.4%), hypertension (59.1% vs. 34.3%), and dyslipidemia (43.2% vs. 14.3%). Patients with SCS showed a smaller median tumor size compared to those with NFA (2.5 cm vs. 5 cm). No significant perioperative complications ≥ Clavien-Dindo classification grade III were observed in any patient (SCS or NFA group). In terms of their metabolic profile, patients with SCS showed a significant postoperative improvement in hypertension (50.0%), diabetes (53.9%), dyslipidemia (31.6%), and obesity (29.2%). However, patients with NFA showed a postoperative improvement only in dyslipidemia (40.0%) and obesity (4.8%). CONCLUSIONS: Owing to absence of significant perioperative complications and the marked postoperative improvement in metabolic impairment, LA is a useful treatment strategy in patients diagnosed with SCS. In contrast, LA was not observed to show beneficial effects in correcting/improving the metabolic profile in patients presenting with NFA.

PURPOSE: The efficacy of the prostate-specific antigen (PSA), prostate-specific antigen density (PSAD), digital rectal examination (DRE) and transrectal ultrasonography (TRUS) for diagnosing prostate cancer in Koreans was investigated. MATERIALS AND METHODS: The medical records from a selected population of 346 patients (30 to 93 years old, mean age 66.0) who had visited the department of Urology in Seoul National University Hospital from January 1994 to December 2000 were reviewed retrospectively. All patients a transrectal ultrasonography-guided biopsy. The student's t test was used for statistical analysis. RESULTS: Prostate cancer was detected in 119 (34.4%) out of 346 patients. PSA, PSAD, TRUS, and DRE showed a sensitivity of 95.8%, 88.2%, 66.4% and 61.3%, a specificity of 26%, 49.3%, 66.5% and 55.9%, and a positive predictive value of 40.4%, 47.7%, 51% and 42.2%, respectively. The positive predictive value from the combination of PSAD and TRUS was 67%, which was the highest when two among the four methods were selected and combined. The detection rate for prostate cancer was 23% (31 out of 135 patients) when the PSA level was between 4 and 10ng/ml, and was 20.9% (18 out of 86 patients) when PSA level was between 4 and 10ng/ml and the DRE findings were negative. CONCLUSIONS: In detecting prostate cancer, PSA showed the highest sensitivity and TRUS showed the highest specificity and positive predictive value. PSAD might be a useful method for diagnosing prostate cancer when combined with TRUS. A TRUS-guided biopsy should be done in patients when the PSA level is between 4 and 10ng/ml in Korea.
