Tubular apocrine adenoma is a well-circumscribed intradermal benign tumor with tubular structures showing apocrine differentiation. Most of those cases occur on the scalp in middle aged women. Histologically, tubular structure with apparent apocrine decapitation secretion, cystic dilatation of tubule, and connection with epidermis are the characteristic features of tubular apocrine adenoma. We presented a case of tubular apocrine adenoma that had recurred after incomplete excision. It showed apocrine decapitation secretion histologically and both eccrine and apocrine differentiation on immunohistochemical study.

Trichoblastoma includes all benign follicular germinative cell tumors in skin. We presented a case of trichoblastoma which occurred on the scalp as a large pedunculated tumor. The tumor was composed of lobular aggregations of basaloid epithelial cells and numerous primitive papillary mesenchymal bodies. Stromal retraction was observed between the stroma adjacent to epithelial nests and surrounding normal dermis. Focal connection to the overlying epidermis was observed. The classification and terminology for the benign neoplasms with follicular differentiation was discussed.

OBJECTIVES: We have previous reported that thawed testicular sperm and sperm extracted from seminiferous tubule could achieved optimal fertilization and pregnancy in azoospermic patients. However, thawed testicular sperm did not show motility in many cases. Therefore we studied viability of immotile sperm extracted from frozen-thawed seminiferous tubule using hypo-osmotic swelling (HOS) test and eosin-Y test. MATERIALS AND METHODS: After sperm extraction using for ICSI, the remained sections of seminiferous tubules were frozen with computerized freezer. For thawing and preparation of testicular sperm, the seminiferous tubules were thawed by removing from LN2 and letting them at room temperature for 10 min followed by 37degrees C water bath for 10 min. The prepared samples were washed for free of preservation medium and sperm preparation method described previous. Sperm was suspended in 0.1 ml hypoosmotic solution. After 30 minutes, the type of distally coiled sperm were assessed. RESULTS: In 44 cases of cryopreservation of seminiferous tubules in obstructive azoospermic patients, the fertilization rates with 2PN were 71.4% and pregnancy rates were 34.1%. The presence of motile spermatozoa on subsequent post-thaw testicular sperm remarked 15.1% and were increased to 77.3% just before ICSI. After sperm extracted from frozen-thawed seminiferous tubule, 3 hrs later in in vitro culture, the cases of presence of motile sperm, reaction of hypo-osmotic swelling test and viable sperm were 63.6% (28/44), 93.2% (41/44), and 77.3% (34/44), respectively. CONCLUSIONS: Just after post-thawed testicular sperm did not showed motility. Although motility was gained after in vitro culture, many cases showed non-motile sperm until optimal insemination time. However, HOS test showed positive reaction in non-motile sperm. Therefore, HOS test is an alternative method for the selection of viable sperm for ICSI.

Fibrolipoma is a rare histological variant of lipoma characterized by proliferation of mature fat and fibrous tissue. Most of the benign lipomatous tumors in the palm reported in the literature developed in the nervous tissue, especially the median nerve sheath. We report an unusual form of fibrolipoma on the palm which arose from the subcutaneous tissue or superficial palmar fascia in the palm, not the nerve or tendon sheath. There was no recurrence 3 years after surgical removal was performed.

PURPOSE: Chronic allograft nephropathy is the most common cause of renal transplant failure in the first post-transplant decade, but its pathogenesis has remained unclear. The most effective option to prevent chronic allograft nephropathy is the prevention of graft injury from both immune and non-immune mechanisms. To prevent chronic allograft rejection as avoiding high risk factors in donor selection, we analyzed the potential risk factors of chronic allograft rejection in renal transplantation. METHODS: Retrospective review was performed on clinical courses of 592 recipients of renal transplantation treated with cyclosporine, azathioprine or mycophenolate mofetile and prednisone from January, 1985 to December, 2000 in Hanyang University Hospital. Of 592 cases, chronic rejection was occurred in 51 cases, we analysed this group. The control group was demographically matched using the parameters of age, gender, date of transplantation, and immunosuppressive protocol, the numbers of control group was 98 cases in same period. We compared with two groups for risk factors, such as donor age, HLA mismatching, acute rejection episode and frequency, and proteinuria at 1 month after transplantation. We identified statistical analysis using univariate logistic regression analysis with SPSS program. The data comparison was performed through chi-square test. RESULTS: The average age of recipient is 33.8 years and that of donor is 45.5 years in chronic rejection group. Acute rejection episode was 51% (26/51) compared with control group 10.2% (10/98). Univariate analysis of risk factors revealed that acute rejection episode (P=0.000), HLA-DR mismatching (P=0.000), and donor age (P=0.000) were significant independent risk factors. CONCLUSION: We suggested that acute rejection episode, over 50 years of donor age and the degree of HLA-DR mismatching were the risk factors of chronic rejection. And so, in selecting donor for living donor renal transplantation, we should concern donor age, HLA-DR mismatching, and aggressive treatment in occurring acute rejection episode after transplantation.

BACKGROUND: Organophosphate insecticides poisoning is one of the most common toxicologic emergencies in Korea. There have been few reports of organophosphate intoxication via parenteral route, although many reports on organophosphate intoxication by oral ingestion were present in the literature. This study aimed to validate the clinical characteristics of organophosphage intoxication according to the route of administration to the body. METHOD: Data were collected retrospectively by the review of the medical records from 49 patients with organophosphate intoxication. Severity of intoxication was classified by the Namba's Classification. Collected data were analysed and compared on the clinical features and laboratory findings between the patient intoxicated by inhalation or contact(parenteral group, n=23) and the other oral ingestion(enteral group, n=26). RESULTS: Severity class by clinical features was higher in enteral group than parenteral group. Severity class by serum cholinestetrase level was not positively correlated with severity class by clinical manifestations. Cholinesterase level tended to overestimate the severity of intoxication in parenteral group. Ventilator therapy and admission to intensive care unit were more frequently needed in enteral group than parenteral group in case that the severity class by clinical features was equal. CONCLUSION: In patients with organophosphate intoxication by parenteral route, serum cholinesterase level of the patient had disparity with clinical severity of intoxication. Considering this disparity, clinical severity should be considered as a more important indicator for treatment of organophosphate intoxication including atropinization, rather than serum cholinesterase level in patients intoxicated by parenteral route.

BACKGROUND: Septic shock is characterized by an abnormal vascular tone that has been related to various factors. Myocardial depression can also occur in septic shock. Various experimental studies have indicated that the myocardial depression could be present early in the course of septic shock. This study aimed to assess hemodynamic characteristics according to outcome of septic shock in emergency department. METHOD: The study population comprised 20 patients admitted to our emergency department for septic shock. All patients with septic shock(prolonged hypotension, signs of tissue hypoperfusion, signs of sepsis, suspected source of infection, or documented bacteremia) had conventional serial hemodynamic evaluations in emergency department to identify early hemodynamic variables that predicted outcome. All patients were monitored with a pulmonary artery catheter and an arterial catheter. Hemodynamic measurements and oxygen profile were obtained. RESULTS: There were 9(53%) survivors and 8(47%) nonsurvivors. There were no significant differences in systolic pressure, pulse rate, mean pulmonary artery pressure, pulmonary capillary wedge pressure, systemic vascular resistance index, and pulmonary vascular resistance index between survivors and nonsurvivors at initial hemodynamic value. However, significant differences were found in cardiac index(4.3+/-0.5 vs. 2.74+/-0.7 L/min/m2), stroke volume index(44+/-10 vs. 23+/-5 ml/beat/m2), left ventricular stroke work index(39+/-11 vs. 15+/-6 gm m/m2), and right ventricular stroke work index(8.1+/-3.0 vs. 5.2+/-2.9 gm m/m2) between survivors and nonsurvivors at initial hemodynamic value. CONCLUSION: Survivors had better myocardial function than nonsurvivors during the early phase of septic shock. This results suggest that myocardial depression during septic shock develops in the early course of septic shock, which is associated with outcome.
