The histogenesis and differentiation of sweat gland tumors are controversial. Twenty-two cases of sweat gland tumors were stained by immunoperoxidase technique (ABC method) for the presence of S-100 protein, CEA, and two kinds of keratin. Four syringomas, 4 eccrine poromas, 2 eccrine porocarcinomas, 2 eccrine spiradenomas, 1 papillary eccrine adenoma, 3 clear cell hidradenomas, 3 mixed tumors of skin, 2 papillary syringocystadenomas, and 1 cylindroma were included. All samples were formalin-fixed and paraffin-erribedded. Two monoclonal cytokeratin ant.ibodies, MA-902 (specific for cytokeratin No. 8) and MA-903 (specific for cytokeratins No.1,5,10,11) were used. In normal eccrine and apocrine glands, MA-902 stains cells of the intradermal duct and secretory portion. While MA-903 stains cells of the intraepidermal and intradermal duct and myoepithelial cells of eccine and apocrine glands, S-100 protein is found in the secretory cells of the intradermalduct and secretory portion, while CEA stains the secretory and ductal cells of eccrine and apocrine glands. All sweat gland tumors we studied stained by 4 antibodies in variable positive rates, Based on these findings, we discuss the histogenesis of various sweat gland tumors.

Primary squamous cell carcinoma of the colon is an extremely rare malignancy. A 48-year-old male visited our hospital for screening colonoscopy. Colonoscopic examination showed a 1 cm sized sessile polyp in the ascending colon. The patient underwent endoscopic mucosal resection (EMR) without any complication. The pathologic findings were compatible with squamous differentiation of tumor cells in inflammatory colonic mucosa. The tumor was confined to the mucosa and the margins of the excised tissue were found to be free of the tumor. There were no other primary sites and no distant metastases in the extensive evaluation using a whole body CT scan and PET-CT. Additional surgical resection was not done. Follow-up colonoscopy performed eight month later showed a whitish scar without evidence of local recurrence and follow-up PET-CT demonstrated no evidence of recurrence. Herein, we report a case of primary squamous cell carcinoma of the ascending colon presenting as a sessile polyp which was removed by EMR.

PURPOSE: To find out the efficacy, safety and early complication of radiofrequency catheter ablation(RFCA) in pediatric patients with paroxysmal tachycardia, we compared short-term results of RFCA in pediatric patients to adult patients. METHODS: We studied 25 patients(11 pediatric patients, 14 adult patients), who underwent RFCA due to paroxysmal supraventricular tachycardia(PSVT) or idiopathic ventricular tachycardia(VT) from November 1997 to August 1998. We evaluated PSVT or idiopathic VT mechanism and compared total procedure times, total energy durations and complication rates between pediatric patients and adult patients. RESULTS: Among the 25 patients, the mechanisms of tachycardia were atrioventricular reentrant tachycardias in 14 patients, atrioventricular nodal reentrant in 10 patients and idiopathic left ventricular in 1 patient. Among the 11 pediatric patients, atrioventricular reentrant was found in 9 patients, atrioventricular nodal reentrant in 1 patient and idiopathic left ventricular in 1 patient. while among the 14 adult patients, atrioventricular reentrant was found in 5 patients and atrioventricular nodal reentrant in 9 patients. Total procedure time was 190+/-52 minutes in pediatric patients and 161+/-49 minutes in adult patients(P=0.17). Total energy duration was 244+/-223 seconds in pediatric patients and 187+/-122 seconds in adult patients(P=0.45). There were no major complications related to RFCA except minor hematomas at puncture sites. CONCLUSION: Considering the total procedure time, total energy duration and complication rates, there were no significant differences between pediatric patients and adult patients. RFCA showed relatively high success rate and one recurrence after initial success. Thus, we consider RFCA is as a good therapeutic modality which can cure tachycardia, especially PSVT.

A clinical and laboratory study was conducted on 58 children who had been admitted to out pediatric department from February to September 1979, under the clinical diagnosis of septicemia. Following results were obtained: 1. Boys were affected more frequently than girls(1.3:1), and highest incidence was noticed in newborn period, comprising 50% of the total cases. 2. The common clinical manifestations, in order of frequency, were fever, lethargy, jandice, poor sucking and abdominal distension, and hyperbilirubionemia was the most common assocaited disease, followed by anemia and leukemia. 3. Clinical course revealed death in 6 patients(10.3%), discharge against advice in 7cases(21.1%) and complete recovery in the remaining 45 cases(77.6%). 4. Peripheral blood count showed leukocytosie in 40%, leukopenia in 12.1% and thrombocytopenia was seen in 45% of cases. 5. Gram staining of buffy coat smear showed bacteria in 34.5% and especially high ratio was noticed in newborn infants(48.3%). 6. Positive blood culture was seen in 39.7% with highest ratio of 45% in newborn infants. In positive blood culture group, toxic granules were noted in 32.8%, shift to left in 25.9%, hrombocytopenia in 18.9% and positive buffy coat smear in 15.5%. In summary, thrombocytopenia, toxic granules, shift to left were quite helpful in early diagnosis of sepsis. In addition to diagnostic value, examination of buffy coat smear could aid physician to select appropriate antibiotic regimen especially in sepsis of newborn period.

OBJECTIVE: Total intervertebral disc replacement is designed to preserve motion and avoid limitations of fusion after removing local pathology. The authors report the results of a signle-center study to determine functional and radi- ologic outcomes associated with cervical total disc replacement versus those of cervical fusion. METHODS: We retrospectively reviewed the charts and radiographs of patients who underwent a total intervertebral disc replacement(TDR) or a single-level anterior cervical fusion(ACDF) between January 1, 2004, and September 31, 2007. Clinical symptom was assessed using the Visual Analog Scale(VAS) of the neck and of the arm pain. Range of motion was determined by radiologic assessment of flexion-extension radiographs. Data were collected before surgery and at 6 weeks, 3, 6, 12, and 24 months after surgery. RESULT: A total of 125 patients were identified with 63 having TDR(43 males and 20 females) and 62 having fusion(42 males and 20 females). The average age was 49.1 years(TDR) and 51.7 years(ACDF)(p=0.229). The mean neck pain VAS before surgery was 6.52(TDR) and 6.61(ACDF)(p=0.732). At 2-year follow-up, the average neck pain VAS for the TDR group was 1.59 and ACDF 1.85(p=0.168). The mean arm pain VAS before surgery was 6.37(TDR) and 6.60(ACDF)(p=0.335). At 2 years: 1.41(TDR) and 1.65(ACDF)(P = 0.148). More motion(an average of 9.00 degrees at 24 months) was retained after surgery in the TDR group than the fusion group at the treatment level. There was no significant diffe- rence in motion at adjacent levels. CONCLUSION: Total disc replacement maintained physiological segmental motion at the 2-year follow-up. The finding that there was no statistically significant difference between the groups in motion at adjacent levels must be verified on further studies.

rpoB, which encodes the B subunit of RNA polymerase, is related to rifampin resistance of Mycobacterium tuberculosis and Escherichia coli. We determined the nucleotide sequences (346 bp) of rpoB gene from 25 Korean isolates of Helicobacter pylori. These nucleotide sequences were aligned and compared with H. pylori 26695 strain. No insertions or deletions were observed in all H. pylori strains. In the phylogenetic tree constructed by UPGMA method, 26 strains of H. pylori were separated into four clusters. Deduced amino acid sequences of amplified rpoB DNA comprised 115 amino acid residues. Twenty six H. pylori strains could be divided into 5 groups by the signature amino acid sequences. Two strains isolated from the same patient showed different nucleotide sequences. These results suggest that the sequences of rpoB are also highly divergent in H. pylori isolates and are useful for the epidemiologic study.

Bizarre parosteal osteochondromatous proliferation (BPOP) is an rare benign tumor which involve mostly tubular bones of feet and hand. BPOP has clinical, radiographic, and histologic similarities with osteochondroma.Radiologically, BPOP has not central continuity with underlying osseous medulla. Histologically, the lesion has marked proliferative activity, and enlarged, bizzare, and binucleated chondrocytes.Despite the high risk of recurrence, treatment of choice is surgical resection. This report presents two cases of BPOP of the big toe with reviews of clinical, radiographic, and histological characteristics.

Extramammary Pagets disease(EMPD) of the vulva is an uncommon neoplasm which accounting for 2.5% of all vulvar malignancies and 0.02% of all female cancer. Several hundred cases have been reported worldwide since the first description by sir James Paget in 1874, It generally affects postrnenopausal age poup and presents high rate of recurrence but the precise incidence remines unclear, Although Paget's disease of the breast and the vulva are histologically similar, their histogenesis and biological behavior are considered to be significantly different and EMPD has gcnerally perceived rnore benign compared to that of the breast. Four histologic forms of vulvar EMPD have been recognized and treated vulvar EMPD in according to the 4 histologic classification. The high rate of recurtence disease remains a challenge for optimal management. Recently we experienced a case of Paget's disease of the vulva, diagnosed as an intraepithelial Pagets disease preoperatively and underwent radical vulvectomy and superiomedial thigh(SMT) flap, and present with a brief review of literature.
