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.

Reactive airways dysfunction syndrome (RADS) is a syndrome as a persistent bronchial hyperreactivity with asthmatic dyspnea which occurs after one or more inhalation exposures to a high concentration of irritant gasses, smokes or vapors in subjects who had preciously had no respiratory disease. We report a case of a 34 years old female worker suffering from reactive airways dysfunction syndrome who had been taking charge of guest room cleaning at a condominium. 7 months before, she inhaled high concentration of chlorine gas in confined and poor ventilated working space of bathroom at the condominium. As she was washing a bathroom with a bleaching agent (6 % sodium hypochlorite) without dilution, dyspnea, dizziness, headache, nausea, and coughing developed after work. She still suffer from dyspnea and coughing. All functional tests were normal except for methacholine challenge test which reveals bronchial hyperreactivity. She has some symptoms of dyspnea and coughing when exposed to perfume, cold air, and heavy work.

Kartagener's syndrome is an autosomaly inherited recessive condition characterized by situs inversus, bronchiectasis, and chronic sinusitis. And recently it was recognized as a subclass of dyskinetic cilia syndrome which caused by a defect in mucociliary transport owing to immotile or dyskinetic beating of cilia. Electron microsopy of cilia from sperm tails, nasal and bronchial epithelium of patients reveals the partial or complete absence of dynein arms. Our four patients were diagnosed as a Kartagener's syndrome by classic triad. We carried out electron microscopy of cilia of the nasal mucosa. And many other tests were done. One patient had squamous cell carcinoma of the lung, and another one patient revealed features of adult respiratory distress syndrome at admission. All patients improved with conservative therapy such as physiotherapy, bronchodilater, antibiotics except one patient who mechanical ventilation was required. A brief review of literature was made.

OBJECTIVE: To review recurrence and prognosis of microivasive squamous cell carcinoma of the cervix that are associated with depth of invasion, pathologic finding and management(conservative or radical treatment) STUDY DESIGN: We conducted retrospective study in order to evaluate the results of therapeutic approaches in 46 patients with microinvasive cervical cancer from Jan 1987 to Oct 1996. RESULT: The mean age of patients was 44.6+ 8.86 years. Only one woman was nullipara, and the mean parity was 2.8, Overall diagnostic accuracy of pap smear and punch biopsy were 54.3% and 79.4%. As the depth of invasion was deeper, the diagnostic accuracy of punch biopsy increased(p<0.05), The confluence pattern and lymphovascular space involvement were observed in 39.1% and 4.9%. The confluence pattern was observed with statistical significant in advanced depth of stromal invasion. In the surgical management, vaginal hysterectomy was done in 28 patients, conization(l patient), total abdominal hysterectomy(8 patients) and radical hysterectomy with pelvic lymph node dissection(9 patients) was done, no positive node was in 104 pelvic lymph node dissected. Though all cone margin was free and all endocervical curettage was negative, residual lesion(2 patients) was present in the hysterectomy after conization, The median follow-up period was 64 months. There was no recurrence in all cases and 5 years survival rate was 100% CONCLUSION: We suggest that microinvasive carcinoma of the cervix may be the disease of good prognosis and no recurrence, and less radical therapy for the patients with microinvasive carcinoma may be sufficient.

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.

OBJECTIVE: The authors investigate the effectiveness and the demerits of the AMSLU(TM) cervical cage used in cervical spinal fusion for correction of cervical degenerative disc disease. METHODS: A total of 19 patients with cervical degenerative disc disease underwent anterior microdiscectomy and the AMSLU(TM) cage fusion. We made a retrospective comparative analysis between cases using the AMSLU(TM) cage and the classical autogenous iliac crest graft(AICG) with plate fixation about operative time, blood loss and hospital stay. The patient's neurological and functional outcomes were assessed on the basis of the modified Odom's criteria. RESULTS: The use of the AMSLU(TM) cage was found to save operative time(mean, 153+/-52min: P=0.004) and blood loss(mean, 236+/-171cc: P=0.032) as compared with the use of AICG. There was no donor-site complications and all patients were tolerable to ambulation at 1 day postoperatively. The patient's clinical success rate was 89% on discharge and 84% at 6 months postoperatively. CONCLUSION: The use of the AMSLU(TM) cage provides several advantages: no donor-site complications, brief instrument procedures, short operative time, small amount of blood loss and satisfactory clinical success rate. But it also has many limitations: short follow up period, kyphotic change and subsidence. Further investigations and clinical applications are necessary to use AMSLU(TM) cage in cases of spondylolisthesis and traumatic cervical disease.

Mycobacterium tuberculosis infrequently infects muscle. We experienced a case of tuberculosis myositis compli-cated with usual interstitial pneumonia(UIP). A 56 year-old male patient was admitted due to erythematous painful swelling on left proximal upper ex-tremity and right inner thigh for 10 months. The level of serum creatine kinase, lactic acid dehydrogenase, serum glutamic oxaloacetic transaminase, serum glutamic pyru-vate transaminase and aldolase were elevated. Electromyo-graphy showed low amplitude, short duration, polyphasic motor unit potentials at left biceps brachii, flexor carpi radialis longus, extensor carpi radialis longus, right adductor longus and early recruitment pattern at right biceps brachii. Mcscle biopy showed the findings compatible with tuberculosis. Interstitial lung disease was suspected on chest x-ray and high-resornance computerized tomography, usual in-terstitial pneumonia(UIP) was confirmed by open lung biopsy. We started anti-tuberculosis medication and pred-nisolone for the treatment of tuberculous myositis and UIP, respectively. After 4 weeks of treatment, patient' s symptoms of myositis were improved. The patient is being followed up for monitoring treatment response to prednisolne for UIP.

BACKGROUND: Blood typing is an essential test for transfusion. Generally, blood typing is performed using a slide test, tube test or microcolumn agglutination test. The aims of this study were to develop a new blood typing kit using micromachining, microfluidics and microseparation methods, and to evaluate the clinical usefulness of the new blood typing kit. METHODS: We designed and manufactured a blood typing microchip using polydimethylsiloxane (PDMS), which contained a microchannel (25~200 micrometer). The blood sample and antisera to be tested were dropped on the microwell for movement and mixing by capillary action. Once agglutination occurred, the microchannel acts as a filter and the blood type was determined by observation by the naked eye. To evaluate the newtyping kit, we tested sensitivity using artificially diluted blood and compared the results of the new typing method with the slide and tube methods using 70 samples. RESULTS: The new blood typing kit could differentiate a +4~+2 agglutination reaction, but could not detect a +1 agglutination reaction as observed by the naked eye. Among 70 samples, the results of ABO and Rh typing by the new typing method (n=66, > or = +2 agglutination reaction by the column agglutination method) were in accord with the results of the tube and slide methods, but couldnot detect agglutination in all 4 clinical samples, below a +1 agglutination reaction. CONCLUSION: The new blood typing kit is inadequate for routine use in the clinical laboratory due to low sensitivity, but with further improvement, it can be used economically, conveniently and objectively for blood typing without any special equipment. Moreover, the microfludics and separation method may be broadly applicable in other tests using the hemagglutination method.

OBJECTIVE: To investigate the clinical usefulness of scintigraphy for the evaluation of dysphagia in patients with brain lesion and to clarify the most useful quantitative parameter for detection of aspiration using scintigraphy. METHOD: For 42 patients with dysphagia, swallowing evaluations were done by videofluoroscopy and scintigraphy. According to videofluoroscopic findings these patients were grouped into three; aspiration, laryngeal penetration and no penetration group. Quantitative parameters from scintigraphy were measured and compared among three patients groups and normal control; these parameters were oral discharge time (ODT), pharyngeal transit time (PTT), oral residue (OR), pharyngeal residue (PR), pharyngeal swallowing efficiency (PSE) and oro-pharyngeal swallowing efficiency (OPSE). Sensitivity and specificity of these parameters detecting aspiration were also evaluated according to the videofluoroscopic findings. RESULTS: In aspiration group ODT, PTT, PSE and OPSE were 1.18+/-1.14 sec, 1.80+/-1.49 sec, 86.05+/-61.42%/sec and 38.21+/- 28.65%/sec respectively, all of which were significantly different from the other groups, but OR and PR were not different statistically. According to the ROC (Relative Operating Characteristic) table, sensitivity and specificity of OPSE were 72.7 and 80.7% respectively, which were the highest among the parameters. CONCLUSION: Scintigraphy was useful to quantitative dysphagia in patients with brain lesion. Sensitivity and specificity of swallowing efficiency was higher than time and residue parameters. OPSE was considered to be the most useful quantitative parameter for detecting aspiration.
