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.

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.

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.

The combination of testicular sperm extraction (TESE) with ICSI can achieve normal fertilization and pregnancy rate and is affective method in obstructive and non-obstructive azoospermic patients. But, when pregnancy was not occurred, repeated testicular biopsies are not evitable. Therefore, in this study, we observed the survival rate of testicular spermatozoa and spermatozoa extracted from the seminiferous tubules after cryopreserved-thawed used for next IVF cycle with ICSI. In a total of 23 cases, obstructive azoospermia was 17 cases and non-obstructive azoospermia was 6 cases. In obstructive azoospermia, after thawing, motile spermatozoa was observed in 13 cases (76.5%). The fertilization rate with 2PN was 67.6% and 5 pregnancies (29.4%) were achieved. In non-obstructive azoospermia, motile spermatozoa was observed in 2 case (33.3%) after thawing. The fertilization rates with 2PN was 53.7% and 3 pregnancies (50.0%) were achieved. A comparison of the results of motile spermatozoa after thawed testicular spermatozoa find spermatozoa extracted from the thawed seminiferous tubule section were 3 cases (60.0%) and 12 cases (86.6%), respectively, The fertilization and pregnancy rates of thawed testicular spermatozoa and spermatozoa extracted from the thawed seminiferous tubule section were 69.4% and 20.0%, 62.5% and 38.8%, respectively. Conclusively, thawed testicular spermatozoa and spermatozoa extracted from the thawed seminiferous tubule section can achieve normal fertilization and pregnancy and cryopreservation of testicular spermatozoa and seminiferous tubule may avoid repetition of testicular biopsies in azoospermic patients in whom the only source of spermatozoa is the testis.

BACKGROUND: Ski injuries depend on many factors which involve the skier's skill, the skiing environment, and skier's equipment. The purpose of this study was to determine the factors associated with fractures by skiing accident. SUBJECT: We evaluated 566 patients with ski injuries who visited to the emergency post located in the YongPyong Ski Resorts from Nov. 1996 to Feb. 1997. Among the patients,379 patients had no fracture(group I) and 187 patients had fracture(group II). RESULT: There was no differences in mean age and sex ratio between two groups. Fractures of the lower extremities were more common than the upper extremities. Slipping was the most common injury mechanism. arming-up was done in 40% of group I and in 17% of group II. The fracture injuries were more common in the skier with intermediate(45%) skill than the beginner(29%) and the ones with advanced skill(12%). The slope with intermediate difficulty was the most frequent site of fracture accidents. The fracture group tended to choose the slope beyond their skiing ability. CONCLUSION: Our results suggest that fracture during skiing can be prevented if skiers do warming-up prior to skiing and choose slope appropriate to their skiing skill.

BACKGROUND: induction of analgesia is frequently required during undergoing reduction of fractures or dislocation in the emergency department. METHODto induce analgesia should be easy, convenient, and safe because patients are not always in fasting state. Nitrous oxide inhalation has been known as a good method of analgesia in emergency patients. PURPOSE: This study was aimed to evaluate the efficacy and safety of nitrous oxide analgesia in the emergency department. METHOD: We prospectively studied 34 patients undergone reductions of fractures in the emergency department. Nitrous-oxide was the sole source of analgesia. The Visual Analogue Scale(VAS) was rated by the emergency physician before nitrous oxide inhalation,5 minutes after inhalation and reduction procedures. RESULTS: No complication such as vomiting, respiratory depression, or a change in oxygen saturation resulted from the use of nitrous-oxide. Ninety one percent of patients obtained an analgesic effect. However, 9% of patients did not experience any analgesic effect after inhalation of nitrous oxide. In subgroup analysis for analgesic effect of nitrous-oxide, nitrous oxide provided only partial analgesia for acute pain in open fracture group. VAS was significantly lower after inhalation than before inhalation of nitrous oxide in simple fracture group. However, VAS of simple fracture group was increased during closed reductions, which indicated incomplete relief of pain by nitrous oxide. Nitrous oxide inhalation foiled to relieve pain during reduction in patients with open fracture or dislocation. CONCLUSION: Administration of nitrous-oxide, when used as the sole source of analgesia, is not the ideal method of analgesia during reduction of fractures or dislocations.

Transcutaneous cardiac pacing(TCP) is a rapid, safe, noninvasive and easily utilized form of emergency cardiac pacing, with hemodynamically similar to transvenous cardiac pacing. This paper reports the result of transcutaneous pacing in a series of patients in emergency department.32 patients with bradyanhythmia were enrolled during the study period. TCP was successful in 29(91%) patients. No evidence of electrical capture was seen in two patients in asystole and a patient with ventricular escape rhythm. Mean capture threshold was 66 mA. Transvenous pacemaker was inserted in 18(56%) of the 32 patients during transcutaneous cardiac pacing. Twenty(61%) of the 32 patients survived and eventually discharged. Ten patients(31%) were died of uncorrectable underlying disease in spite of successful ECG capture and palpable pulse by TCP. In conclusion, TCP is a reliable, noninvasive method that offers the possibility to initiate pacing within seconds and can be used by any emergency medical staff. In our opinion, it should be considered as the first choice of emergency treatment of hemodynamically unstable bradyarrhythmia.
