The incomplete obliteration of the processus vaginalis leads to the development of inguinal hernia in pediatric age, and its management is principally surgical repair. This study was a review and analysis of the usefulness of herniography on the hydrocele in pediatric age. From January 1985 to June 1989, 117 patients with unilateral hydrocele were studied to evaluate incomplete obliteration of the processus vaginalis. The over-all incidence of open processus vaginalis on the opposite side was 6.9% (8 of 117 cases), but the rate of patients who had past history of a palpable or visualized mass on the opposite side was 5%(3 of 12 cases). This finding would suggest that the herniogram is needed for the patients whose history is suspicious for hydrocele testis.

Penile amputation is quite rare and requires emergency reimplantation by using microvascular surgery. Herein we report a case of an 8-year-old boy who accidentally has his penis amputated during circumcision. Emergency reimplantation was performed by using microvascular surgery. Thereafter partial necrosis of glans penis and distal penile skin was noted So penoplasty by using scrotal skin was done to restore normal shape penis. After 6 months later, normal erection and sensation were restored.

PURPOSE: To investigate the results when using the acellular dermal allograft (SureDerm(R), Hans Biomed Co., Korea) as a new wrapping material for porous orbital implants. METHODS: The charts of 11 patients who underwent either primary or secondary insertion of Medpor(R) orbital implants after enucleation or a new insertion after removal of previous orbital implants were reviewed. Medpor(R) orbital implants either 18 or 20 mm were wrapped with SureDerm(R) in 4x4 cm sections that were 1-mm-thick. Four rectus muscles were fixed to the SureDerm(R) wrapped implant, and a conjunctival suture was made with 6-0 Vicryl. All patients had follow-up periods longer than 10 months and were evaluated to determine the success of wrapping and to identify any complications. RESULTS: The average age of the patients was 48.3 years. The patients wore artificial eyes for 9 weeks after the operation, and the follow-up periods were 22.4 months on average. There was no case of implant or SureDerm(R) exposure, inflammation, and other significant complications except in one case that required fornix reconstruction to allow the subject to wear an artificial eye. CONCLUSIONS: Acellular dermal allograft appears to be a good substitute material if preserved sclera is not available when inserting orbital implants with wrapping.

Alport's syndrome, first described by Alport in 1927, is a clinical entity which consists of lens abnormalities, hereditary hemorrhagic nephritis and nerve deafness. Anterior lenticonus is a rare structual anomaly of lens in which there is a conicalor spherical protrusion of the anterior lens surface into the anterior chamber as a characteristic finding of Alport's syndrome. The authers experienced a case of Alport's syndrome in a 22-year-old man associated with bilateral anterior and posterior lenticonus, hematuria, proteinuria, renal failur earld nerve deafness(complete form).

A 61-year old man visited to our hospital due to gross hematuria and voiding difficulty. Microscopic examination of the prostatic tissue revealed a tumor composed predominantly of signet ring cells. Signet ring cell adenocarcinoma of the prostate is extremely rare disease. Recently we have experienced a case of signet ring cell adenocarcinoma of the prostate and report it with brief review of literature.

BACKGROUND: Since 2007 when anaplastic lymphoma kinase (ALK) rearrangements were discovered in non-small cell lung cancer, the ALK gene has received attention due to ALK-targeted therapy, and a notable treatment advantage has been observed in patients harboring the EML4/ALK translocation. However, using ALK-fluorescence in situ hybridization (FISH) as the standard method has demerits such as high cost, a time-consuming process, dependency on interpretation skill, and tissue preparation. We analyzed the histologic findings which could complement the limitation of ALK-FISH test for pulmonary adenocarcinoma. METHODS: Two hundred five cases of ALK-positive and 101 of ALK-negative pulmonary adenocarcinoma from January 2007 to May 2013 were enrolled in this study. The histologic findings and ALK immunohistochemistry results were reviewed and compared with the results of ALK-FISH and EGFR/KRAS mutation status. RESULTS: Acinar, cribriform, and solid growth patterns, extracellular and intracellular mucin production, and presence of signet-ring-cell element, and psammoma body were significantly more often present in ALK-positive cancer. In addition, the presence of goblet cell-like cells and presence of nuclear inclusion and groove resembling papillary thyroid carcinoma were common in the ALK-positive group. CONCLUSIONS: The above histologic parameters can be helpful in predicting ALK rearranged pulmonary adenocarcinoma, leading to rapid FISH analysis and timely treatment.

PURPOSE: We wanted to determine the clinical characteristics and prognosis according to the VEGF expression in stage II cervical carcinoma patients treated with definitive radiotherapy. MATERIALS AND METHODS: We enrolled 31 patients who were diagnosed with cervical cancer from 1995 to 2003 at Samsung Medical Center and their paraffin block tissue samples were available for study. The median age of the patients was 65 years. The mean tumor size was 4.1 cm (range: 1.2~8.2 cm). Seven patients (22.6%) were suspected of having pelvic lymph node metastasis. An external beam irradiation dose of 45-56.4 Gy was administered to the whole pelvis with a 15 MV linear accelerator, and an additional 24 Gy was given to point A by HDR intracavitary brachytherapy. VEGF staining was defined as positive when more than 10% of the tumor cells were stained. The median follow-up duration was 58 months. RESULTS: A positive VEGF expression was observed in 21 patients (67.7%). There was no significant correlation between the VEGF expression and pelvic lymph node metastasis, tumor size and the response of radiotherapy. During follow-up, 7 patients had recurrence. The complete response rate was not significant between the VEGF (-) and VEGF (+) tumors. However, the VEGF (+) tumors showed a significantly higher recurrence rate in comparison with the VEGF (-) tumors (p=0.040). The three year disease-free survival rates were 100% and 66.7%, respectively, for patients with VEGF (-) or VEGF (+) tumor (p=0.047). CONCLUSION: The VEGF expression was a significant factor for recurrence and disease-free survival. However, the significance of the VEGF expression is still controversial because of the various definitions of VEGF expression and the mismatches of the clinical data in the previous studies.

The present study was undertaken to investigate the influence of hypothermia on endothelium-independent vascular smooth muscle contractility and to determine the mechanism underlying the relaxation. Denuded aortic rings from male rats were used and isometric contractions were recorded and combined with molecular experiments. Hypothermia significantly inhibited fluoride-, thromboxane A2-, phenylephrine-, and phorbol ester-induced vascular contractions regardless of endothelial nitric oxide synthesis, suggesting that another pathway had a direct effect on vascular smooth muscle. Hypothermia significantly inhibited the fluoride-induced increase in pMYPT1 level and phorbol ester-induced increase in pERK1/2 level, suggesting inhibition of Rho-kinase and MEK activity and subsequent phosphorylation of MYPT1 and ERK1/2. These results suggest that the relaxing effect of moderate hypothermia on agonist-induced vascular contraction regardless of endothelial function involves inhibition of Rho-kinase and MEK activities.

PURPOSE: We wanted to investigate the accuracy of axillary ultrasonography for detecting axillary nodal metastasis in patients with T1-2 breast cancer and we also wanted to determine the factors affecting the sensitivity. MATERIALS AND METHODS: Two radiologists performed axillary ultrasonography in 119 consecutive patients with T1-2 breast cancer and clinically uninvolved axillae. We analyzed the accuracy of ultrasonography for detecting axillary nodal metastasis with the histologic results being used as a reference standard. We evaluated the number of involved lymph nodes, T staging and the histologic grade of the tumors. RESULTS: Axillary nodes were involved in 39% of total patients (46/119); 30% of the patients with T1 cancer and 55% of the patients with T2 cancer. The sensitivity, specificity, positive predictive value and negative predictive value were for 52%, 92%, 80% and 75%, respectively. The sensitivity was significantly lower for the cases with one to two lymph nodes metastasis and T1 cancer than in those cases with 3 or more lymph nodes metastasis and T2 cancer (35% and 75% in the cases with 1-2 cancer and the cases with > 3 lymph nodes metastasis, respectively, p = 0.009; 38% and 68% in the cases with T1 and the cases with T2 cancer, respectively, p = 0.045). CONCLUSIONS: The ultrasonographic sensitivity for detecting axillary lymph node metastasis is low, especially in the cases with one to two lymph nodes metastasis and the cases with T1 cancer. Detailed analysis and adoption of cytologic examination of the axillary lymph nodes are necessary to improue the accuracy of ultrasonography.

The technique of endoscopic submucosal dissection is occasionally used for resection of myogenic tumors originating from muscularis mucosa or muscularis propria of stomach and esophagus. However, endoscopic treatments for esophageal myogenic tumors >2 cm have rarely been reported. Herein, we report a case of large leiomyoma originating from muscularis propria in the upper esophagus. A 59-year-old woman presented with dysphagia. Esophagoscopy and endoscopic ultrasonography revealed an esophageal subepithelial tumor which measured 25x20 mm in size, originated from muscularis propria, and was located at 20 cm from the central incisors. The tumor was successfully removed by endoscopic submucosal dissection and there were no complications after en bloc resection. Pathologic examination was compatible with leiomyoma.
