PURPOSE: Pelvic actinomycosis is a rare infection which presents difficulty in establishing a correct preoperative diagnosis. The aim of this study is to find diagnostic clues for pelvic actinomycosis preoperatively. METHODS: A retrospective analysis performed at Chonbuk National University Hospital identified 9 patients with a diagnosis of pelvic actinomycosis from 1998 to 2006. RESULTS: All patients were women with a history of intrauterine device (IUD) use. Abdominal pain (7 cases), palpable mass (3 cases), defecation difficulty (3 cases) and leucorrhea (2 cases) were the main presenting complaints. The median duration of presenting symptoms was 78 days (range: 10~365 days). The median duration of using an IUD unchanged was 11 years (range: 4~30 years). A correct diagnosis was made in 3 patients (33%) without exploration. All patients were treated with antibiotics after pathologic diagnosis. There was no recurrence. CONCLUSIONS: It is very difficult to diagnose pelvic actinomycosis preoperatively. Howere, if a mass or a pelvic abscess is found in women with an IUD that has been unchanged for a long time, pelvic actinomycosis should be suspected to avoid unnecessary exploration.

CD10, a marker of immature B lymphocytes, is expressed in the developing epithelium of mammary glands, hair follicles, and renal tubules of human fetuses. To assess mesenchymal and stromal expression of CD10, we performed immunohistochemical assays in whole body sections from eight fetuses of gestational ages 15-20 weeks. In addition to expression in urinary tract and intestinal epithelium, CD10 was strongly expressed at both gestational ages in fibrous tissues surrounding the airways from the larynx to lung alveoli, in the periosteum and ossification center, and in the glans of external genitalia. CD10 was not expressed, however, in other cavernous tissues. These findings suggest that mesenchymal, in addition to epithelial cells at specific sites, are likely to express CD10. The glomeruli, alveoli, and glans are all end products of budding or outgrowth processes in the epithelium or skin. However, in contrast to the CD34 marker of stromal stem cells, CD10 was not expressed in vascular progenitor cells and in differentiated vascular endothelium. The alternating pattern of CD10 and CD34 expression suggests that these factors play different roles in cellular differentiation and proliferation of the kidneys, airway and external genitalia.

OBJECTIVE: To compare apparent diffusion coefficient (ADC) of the upper abdominal organs acquired with multiple b-value combinations and to investigate usefulness of normalization. MATERIALS AND METHODS: We retrospectively analyzed data, including 3T diffusion-weighted images, of 100 patients (56 men, 44 women; mean age, 63.9) that underwent liver magnetic resonance imaging. An ADC map was derived with the following six b-value combinations: b1 = 0, 50, 400, 800; b2 = 0, 800; b3 = 0, 50, 800; b4 = 0, 400, 800; b5 = 50, 800; and b6 = 50, 400, 800 s/mm2. ADC values of the right liver lobe, left liver lobe, spleen, pancreas, right kidney, and left kidney were measured. ADC values of the spleen were used for normalization. Intraclass correlation coefficients (ICCs), comparison of dependent ICCs, and repeated-measures analysis of variance were used for statistical analysis. RESULTS: Intraclass correlation coefficients of the original ADC revealed moderate to substantial agreement (0.5145–0.6509), while normalized ADCs revealed almost perfect agreement (0.8014–0.8569). ICC of normalized ADC for all anatomical regions revealed significantly less variability than that of the original ADC (p < 0.05). Coefficient of variance for normalized ADC was significantly lower than that for the original ADC (3.0.3.8% vs. 4.8.8.8%, p < 0.05). CONCLUSION: Normalization of the ADC values of the upper abdominal organs using the spleen as the reference organ significantly decreased variability in ADC measurement acquired with multiple b-value combinations.

BACKGROUNDS/AIMS: The aim of this study is to analyze surgical outcomes and prognostic factors affecting survival after surgical resection in patients with gallbladder cancer. METHODS: We retrospectively reviewed 86 patients treated surgically for gallbladder cancer from January 2000 to December 2009 at Chonbuk National University Hospital. Clinicopathologic factors, surgical treatment and outcome data were analyzed. RESULTS: Among the 86 patients (44 male, 42 female) with gallbladder cancer, the mean age was 62.9 years (range: 32-80) and the median survival was 42.4+/-3.5 month. The overall cumulative survival rates of 86 patients were for 1 year, 83.7%; 3 year, 67.4%; 5 year survival, 61.7%. Univariate analysis revealed that preoperative serum alanine aminotransferase, alkaline phosphatase, total bilirubin, carcinoembryonic antigen (CEA), T staging, N staging were statistically significantly associated with survival. CEA (p=0.004) and T staging (p=0.005) were associated with survival in multivariate analysis. Two-year survival rates were analyzed according to the methods of surgical resection, with simple cholecystectomy showing 100%, whereas extended cholecystectomy showed about 83% in T1b. We could not find out any adverse effect of the simple cholecystectomy for survival. CONCLUSIONS: CEA and T stage are independent significant prognostic factor associated with patient survival in our study. Simple cholecystectomy can be regarded as curative resection in stage T1b. Longer observation periods and more cases will be needed to confirm these conclusions.

OBJECTIVE: To evaluate the effects of high frequency repetitive transcranial magnetic stimulation (rTMS) of the affected hemisphere on the motor recovery and spasticity in chronic post-stroke hemiplegic patients. METHOD: Thirteen chronic stroke hemiplegic patients were randomized to receive real and sham rTMS. rTMS was carried out 10 times at a frequency of 10 Hz with 10 s stimulation followed by 50 s rest, totalling 1,000 stimulations to the affected primary motor cortex using an intensity of 100% of resting motor threshold of unaffected hemisphere. Median nerve H-reflex, modified Ashworth scale (MAS) at elbow and wrist, and manual function test (MFT) were measured at baseline and after 2 weeks of treatment. RESULTS: High frequency rTMS resulted in increased H-reflex latency and decreased H-reflex amplitude and H/M ratio. Also MAS decreased and MFT score increased after 2 weeks of treatment. CONCLUSION: High frequency rTMS in the affected motor cortex might facilitate motor recovery and reduce spasticity in chronic stroke patients.

BACKGROUND: Cutaneous squamous cell carcinoma (SCC), which occurs in keratinocytes of the epidermis and is the second most common skin cancer, has a more invasive growth pattern and higher potential to metastasize than basal cell carcinoma. Total excision of the primary tumor is the treatment of choice. For clear excision of the tumor, invasion depth is one of the most important factors. This study was conducted to clarify the relationship between the size and the invasion depth of cutaneous SCC. METHODS: Twenty-six cases were collected for this prospective study. Frozen biopsies were examined after complete resection of the tumor, followed by histological confirmation by pathological examination. The major and minor axis lengths of the tumor, the invasion depth, and the level of invasion were measured. Recurrence or metastasis was recorded through regular follow-up. RESULTS: The Pearson correlation coefficient was used for statistical analysis. Significant results were observed for the relationship between the major and minor axis lengths and the invasion depth of the tumor (0.747, 0.773). No cases of recurrence or metastasis were observed. CONCLUSIONS: In head and neck cutaneous SCC, the invasion depth of the tumor is closely related to the major and minor axis lengths of the tumor. Therefore, the invasion depth of the tumor can be estimated by measuring the size of the tumor, and a standard vertical safety margin for head and neck cutaneous SCC can be established, which could be helpful in the development of a preoperative reconstruction plan.

BACKGROUNDS/AIMS: Combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) is an uncommon subtype of primary liver cancer that has rarely been reported in detail. This study was performed in order to evaluate the clinicopathological characteristics and prognostic factors of cHCC-CC in single center. METHODS: The clinicopathological features of patients diagnosed and operated with cHCC-CC at Chonbuk National Hospital between July 1998 and July 2007 were retrospectively studied by comparing them with patients with only hepatocellular carcinoma (HCC) who had undergone a hepatic resection during the same period. RESULTS: Ten out of 152 patients who had undergone a hepatic resection were diagnosed with cHCC-CC and thus included in this study (M : F=8 : 2, median age: 52+/-11.1 years). According to the parameters of the 7th American Joint Committee on Cancer T staging, there were 76 (50.0%), 44 (28.9%), 9 (5.9%), 18 (11.8%) and 5 (3.3%) patients with T stages 1, 2, 3a, 3b and 4, respectively. The overall survival period was longer in the HCC only group (68+/-40.4 months) than in the combined cHCC-CC group (23+/-40.1 months) (p<0.0001). The 5-year survival rate was 10% in the cHCC-CC group and 60% in the HCC group (p<0.0001). The disease free survival for patients with cHCC-HCC and HCC were 16+/-37.4 and 51+/-44.3 months, respectively (p<0.0001). Univariate analysis revealed that age, gender, transarterial chemoembolization (TACE), and T stage were statistically significant in terms of patient's overall survival. However, there were no significant clinicopathological factors identified by the multivariate analysis. CONCLUSIONS: Even after the hepatic resection in the HCC, the prognosis is poorer if the patient has cholangiocellular components compared to the usual HCC.

Severe portal vein thrombosis (PVT) is often considered a relative contraindication for living donor liver transplantation due to high associated risks and morbidity. Meanwhile, improvement in operative techniques, resulting in higher success rates has removed PVT from the list of contraindications in deceased donor liver transplantation (DDLT). In this report, we describe a surgical technique for DDLT using polytetrafluoroethylene graft from the inferior mesenteric vein for portal inflow in patient with portomesenteric thrombosis.
