SUMMARY: To investigate the influences on semen parameters and fertilizing capacity of immuno- globulin(Ig) isotypes and regional distribution of antisperm antibody (ASA) on the human sperm surface. Sixty-seven ASA-positive patients were compared with 96 ASA-negative donors. ASAs in semen showed significant negative effects on both semen parameters and fertilizing capacity; in those with ASAs in the sperm head and/or tail, the reductions were significant. In the head as well as the tail, there was close correlation between fertilizing capacity and both IgG and IgA. Both semen parameters and fertilizing capacity are significantly affected by the presence of ASA in semen. In particular, antibodies IgG to sperm head and/or tail, and antibodies IgA to sperm tail appeared to have a highly detrimental effect on fertilizing capacity.

Freys syndrome is characterized by attacks of facial erythema and gustatory sweating occurring in the cutaneous distribution of the auriculotemporal nerve. After sugery, trauma, abscess, or other diseases of the parotid gland, the postganglionic sympathetic and parasympathetic nerve fibers are disrupted. Some misdirected auriculotemporal nerve fibrils join with the distal sympathetic nerves innervating the sweat glands and subcutaneous vessels. We report a case of Freys sindrome in a 6-year old boy without any definite injury to the parotid gland. After considering our case and review of literature of Freys syndrome in children, we conclude that there may be a congenital defect in the auriculotemporal nerve innervation responsible for cases occuring in children.

We studied clinical applicability of the contact transscleral retinopexy using the continuous-wave Nd:YAG (CW-YAG) laser. CW-YAG laser photocoagulation was done over sclera through contact probe in the pigmented rabbit eyes. Cryoretinopexy was also done and their morphologic findings were compared. Acute lesions produced with the laser photocoagulation were noted to have the characteristic white-colored distinct depigmentation. Its microscopic findings were oharacterized by choroidal necrosis, disruption of Bruch's membrane, dispersion of retinal pigment epithelial cells, and disorganization of sensory retina. Acute lesions after the cryoretinopexy were much more broader in its area and showed slight tanslucent retinal edema. Its microscopic findings showed relatively well-preserved choroid including Bruch's membrane. These data demonstrated that the contact transscleral CW-YAG laser retinopexy is capable of inducing more localized, stronger chorioretinal adhesion than the cryoretinopexy.

OBJECTIVE: Angiogenesis is a critical factor in the progression of solid tumors. The mechanisms responsible for angiogenesis in cervical neoplasia, however, are not well defined. Our study was aimed to determine the expression of VEGF(Vascular Endothelial Growth Factor), its receptor(KDR), and TGF-beta1(Transforming Growth Factor-beta1) in cervical neoplasia, to determine the role of these angiogenic factors in preinvasive(dysplastic) process and the progression of cervical cancer and to investigate the progression of angiogenesis in the transition from normal cervix to invasive squamous cell carcinoma of the uterine cervix. METHODS: The cervical lesions of 76 patients were punch biopsied and paraffin embedded. Among these, 5 were normal cervix, 36 were cervical intraepithelial lesion I-III, and the other 35 were invasive squamous cell carcinomas. The tissues were immunostained with antiVEGF, antiKDR, and antiTGF-beta1 polyclonal antibody. RESULTS: The expression of VEGF, KDR, and TGF-beta1 in CIN III was stronger than those of CIN I(p<0.01). Their expression were not significantly different among the each staged cervical cancers(p>0.01). CONCLUSIONS: These observations suggest that VEGF, KDR, and TGF-beta1 are important angiogenic factors in cervical neoplasia, especially in an early event to neoplastic transformation of cervical tissues, but these angiogenic factors are not associated with the progression of cervical cancer.

OBJECTIVES: To assess the fertilizing capacity using sperm penetration assay (SPA) to predict the outcome of the in vitro fertilization-embryo transfer (iVF-ET) outcome. MATERIALS AND METHODS: Semen samples were provided by 129 patients undergoing iVF. We attempted to correlate the extent of sperm penetration under enhanced SPA protocol with the results of fertilization, cleavage, preimplantation embryo development, and pregnancy. RESULTS: Univariate analysis demonstrated a statistically significant correlation between fertilizing capacity and motility, kinetics, fertilization, cleavage and embryo development, and pregnancy rate. By logistic regression analysis, fertilizing capacity was found to be the only variable that was statistically significant with respect to pregnancy rate. Fertilizing capacity, cleavage rate and pregnant rate were significantly higher in pregnant group. However, the fertilization rates was comparable with both group. CONCLUSIONS: Lower fertilizing capacity could denote a poorer prognosis for establishing a pregnancy, even after satisfactory fertilization rate is achieved.

Various types of appendage tumors develop secondarily within lesions of nevus sebaceus. A syringocystadenoma papilliferum is the most common benign tumor while basal cell carcinoma is the most common malignant tumor developed within a nevus sebaceus. However, a squamous cell carcinoma rarely develops within a nevus sebaceus, although it may be aggressive. We report a case of a 44 year-old man who had a fingertip-sized hemorrhagic crusted mass in a 3x4cm sized nevus sebaceus which had developed since birth on the right occipital scalp. This mass has rapidly enlarged into 1x2cm sized growth in the past 4 months. Histopathologic examination of the lesion showed that infiltrative squamous cell carcinoma with good or moderate differentiation indicatied the lesion of nevus sebaceus. Wide excision of squamous cell carcinoma including the whole lesion of nevus sebaceus was performed. Three months later, squamous cell carcinoma recurred in the same part of the scalp. Another wide excision of the recurrence was performed, but recurred again in the same part with invasion into the muscle layer. The recurrence is currently being treated by radiotherapy.

Transepidermal elimination is a mechanism whereby foreign or altered constituents can be removed from the dermis. The phenomenon of transepidermal elimination may occur as a primary process characterizing disorders such as elastosis perforans serpiginosa, reactive perforating collagenosis and chondrodermatitis nodularis chronica helicis; as well as a secondary process characterizing disorders such as granuloma annulare, necrobiosis lipoidica diabeticorum, calcinosis cutis, pseudoxanthoma elasticum, spitz nevi, pimented nevi, porokeratosis plantaris discreta and metastatic tumors. A 17-year-old man presented with a 2X2 cm sized well-circumscribed slightly erythematous plaque with some black colored papules on the left dorsum of his hand. The histopathology of the lesion indicated angiokeratoma circumscriptum with transepidermal elimination.
