The anorectal anomaly is not rarely seen in the neonatal period. But, If it is not accompanied with a fairly large fistula, it presents an urgent problem, so should be managed with perianal anoplasty or colostomy. Neonatal peritonitis is very grave and is caused by various conditions listed in Table 1. In Korea, no case of neonatal peritonitis caused by anorectal has yet been reported in the literature. With brief review of the literature, we present a case of neonatal peritonitis which appeared 36 hours after birth by perforation of the colon due to anorectal stenosis.

Testosterone is required for the development and maintenance of the male accessory sex organs and their normal function. And it was reported that castration affect cells in the adult male rat accessory sex glands by induction of programmed cell death (apoptosis). So, in this study, the authors made an experiment to evaluate the effect of testosterone in the maure male rat penis and accessory sex glands following castration. Also, we utilized actinomycin D, a potent inhibitor of messenger and ribosomal RNA synthesis, in the experiment herein to assess the significance of regression process in the glands. Following are the changes in the serum testosterone level, the weight of the penis, ventral prostate and seminal vesicles and apoptosis occurrence of the control (castration, castration normal saline) and experimental (castration AD25, castration AD50) group of mature rats. 1. After castration, the control group and the experimental group showed decreased level of serum testosterone. 2. In the both groups, the weight of the penis, ventral prostate and seminal vesicles decreased gradually. 3. Compared to the control group, the castration AD25 did not show the inhibition of castration induced regression of penis and ventral prostate. However, castration AD50 showed the inhibition. 4 In the H-E staining and ApoTag in situ staining, the ventral prostate showed the most prominent apoptosis occurrence followed by the seminal vesicles and penis. These results suggest that after castration of the mature rat, due to testosterone deficiency, the weight of penis, ventral prostate and seminal vesicles decreased with the occurrence of apoptosis. Also, actinomycin D 50 micrometer seems to delay the regression process.

BACKGROUND: Some researchers have tried to use Tc-99m MIBI (2-methoxyisobutyl isonitril) scintigraphy to evaluate breast-cancer patients. Early reports revealed that Tc-99m MIBI breast scintigraphy was useful in distinguishing malignancies from benign masses in patients for whom mammographic evaluations were difficult. Further studies suggested that functional imaging with Tc-99m MIBI in breast cancer seemed to be correlated with the levels of P-glycoprotein (Pgp) expression and angiogenesis in cancer tissues. For that reason, we evaluated whether significant relationship actually existed between the pattern of Tc-99m MIBI uptake in tumor tissue and tumoric factors including Pgp expression and angiogenesis. METHODS: Thirty-one untreated breast-cancer patients (later pathologically proved to have had invasive ductal carcinomas) were prospectively studied by using both Tc-99m MIBI scintigraphy on and immunohistochemical analyses of angiogenesis and Pgp expression in sugically removed tumor tissues. Both lateral and anterior planar images were obtained at 10 minutes and 3 hours after intravenous injection of 740 MBq Tc-99m MIBI. The tumor-to-normal breast ratio (T/N) and the washout index (WI, early T/N minus late T/N divided by early T/N) were calculated. RESULTS: A significant correlation was found between the T/N's at early and late images (r=0.54, p=0.002 on early images; r=0.47, p=0.006 on late images). The T/N's of early images were not different among the different groups of Pgp expression (p=0.3696) while those of late images were significantly different among the groups (p=0.0276). An even more significant difference was noted in the WI's among the groups (p=0.0015). A significant negative correlation was noted between the T/N of late images and Pgp expression (p=0.0276). An even stronger correlation was found between WI and Pgp expression (r=0.668, p=0.001). CONCLUSIONS: The tumoral uptake and washout of Tc-99m MIBI can be used as a simple functional test for angiogenesis and P-glycoprotein expression in untreated breast cancer.

BACKGROUND: The presence of cardiac metastasis from cervical cancer is very rare. Due to the rarity of this condition, clinical characteristics of the patients with cardiac metastasis from cervical carcinoma is not well known. This study is to investigate the clinical profiles and outcomes of patients with cardiac metastasis from the carcinoma of the uterine cervix. MATERIALS AND METHODS: From Jan. 1990 to May 1999, 4 patients with cardiac metastasis from cervical cancer during the course of the disease were registered in Korea Cancer Center Hospital. The clinical characteristics of these patients were reviewed retrospectively. RESULTS: Mean age of patients was 49 years, and median interval from initial diagnosis to recurrence was 27 months. Histologically, all 4 cases were squamous cell type carcinoma. The stage distribution is two patients with FIGO stage II, one with stage I and one with stage III. Clinical symptoms of patients were dyspnea and facial edema in 2 patients, facial edema in one patients, and dyspneas only in one patient. All patients were confirmed histologically by pericardiocentesis. Synchronous metastatic lesions were supraclavicular lymph node, lung parenchyme and paraaortic, mediastinal lymph node. Following pericardiocentesis or pericardiodesis, all patients were improved clinically and survived for mean interval of 5.3 months. CONCLUSIONS: The patients with pericardial metastasis from cervical carcinoma showed a short survival time, but could be managed by pericardiocentesis or pericardiodesis with improvement of clinical symptoms.

The treatment options available for patients with hepatocellular carcinoma (HCC) with portal vein invasion (PVI) include sorafenib, transarterial radioembolization (TARE), radiation therapy (RT), transarterial chemoembolization with RT, and proton beam irradiation. Herein, we present a case of HCC with segmental PVI that was managed via TARE. The patient had a 4 cm HCC that invaded the segment VIII portal vein branch without extrahepatic spread. Liver function was Child-Pugh grade A, and performance status was good. TARE was performed without any adverse events, and a radiological complete response (CR) was achieved. Thereafter, the patient was followed-up every 3–6 months without any further treatment, and the CR was maintained for >3 years. Therefore, TARE may be a useful alternative therapeutic option for patients with HCC exhibiting segmental PVI.

Objective:
This study aimed to compare the efficacy between no-touch (NT) radiofrequency ablation (RFA) and conventional RFA using twin internally cooled wet (TICW) electrodes in the bipolar mode for the treatment of small hepatocellular carcinomas (HCC).
Materials and Methods:
In this single-center, two-arm, parallel-group, prospective randomized controlled study, we performed a 1:1 random allocation of eligible patients with HCCs to receive NT-RFA or conventional RFA between October 2016 and September 2018. The primary endpoint was the cumulative local tumor progression (LTP) rate after RFA. Secondary endpoints included technical conversion rates of NT-RFA, intrahepatic distance recurrence, extrahepatic metastasis, technical parameters, technical efficacy, and rates of complications. Cumulative LTP rates were analyzed using Kaplan-Meier analysis and the Cox proportional hazard regression model. Considering conversion cases from NT-RFA to conventional RFA, intentionto-treat and as-treated analyses were performed.
Results:
Enrolled patients were randomly assigned to the NT-RFA group (37 patients with 38 HCCs) or the conventional RFA group (36 patients with 38 HCCs). Among the NT-RFA group patients, conversion to conventional RFA occurred in four patients (10.8%, 4/37). According to intention-to-treat analysis, both 1- and 3-year cumulative LTP rates were 5.6%, in the NT-RFA group, and they were 11.8% and 21.3%, respectively, in the conventional RFA group (p = 0.073, log-rank). In the as-treated analysis, LTP rates at 1 year and 3 years were 0% and 0%, respectively, in the NT-RFA group sand 15.6% and 24.5%, respectively, in the conventional RFA group (p = 0.004, log-rank). In as-treated analysis using multivariable Cox regression analysis, RFA type was the only significant predictive factor for LTP (hazard ratio = 0.061 with conventional RFA as the reference, 95% confidence interval = 0.000–0.497; p = 0.004). There were no significant differences in the procedure characteristics between the two groups. No procedure-related deaths or major complications were observed.
Conclusion
NT-RFA using TICW electrodes in bipolar mode demonstrated significantly lower cumulative LTP rates than conventional RFA for small HCCs, which warrants a larger study for further confirmation.
