1.A Case of Testicular Regression Syndrome.
Journal of Korean Society of Pediatric Endocrinology 2001;6(2):171-175
Testicular regression syndrome may be better known as vanishing testis syndrome to physicians. Such individuals are genetically male(46,XY), presenting with unilateral or bilateral absence of recognizable testis structures and absence of the Mullerian duct system. There is a wide spectrum of phenotypes depending on the stage of male embryogenesis at which testicular function ceased. We experienced a case of testicular regression syndrome presenting labial fusion at birth and report with the brief review of related literature.

If the treatment of acetabular fractures are not satisfactory, there will be serious complication such as traumatic arthritis or avascular necrosis of the femoral head. There is much continuing discussion as to where conservative or surgical treatment should be used. The authors experienced 41 cases of acetabular fractures, that wrere treated at the Department of Orthopaedic surgery, Maryknoll Hospital from January 1981 to September 1987. The results of 29 cases who were followed over a 1 year period are as follows:1. According to Letournel's classification, the most common type of elementray fracture was posterior wall(24.1%) and a T- shsped fracture was 10.3 % and both column fractures were 10.3%. 2. Complications were traumatic arthritis(14 cases), superficial infection(5 cases), ectopic ossification(5 cases), osteomyelitis(1 case), AVN of the femoral head(1 case), and iartrogenic femoral shaft fracture(1 case). 3. According to matta's assessment, satisfactory results of conservative treatment were 38% clinically and 38% radiologically, and by surgical treatment, 73% clinically and 64% radiologically. 4. Surgical treatment in acetabular fractures, such as an anatomical reduction and rigid fixation fixation followed by early joint motion were improved the result and decresed the rate of traumatic arthritis.

4.HPV-18 E7 Interacts with Elk-1 Leading to Elevation of the Transcriptional Activity of Elk-1 in Cervical Cancer

The human papillomavirus (HPV)-18 E7 (E7) oncoprotein is a major transforming protein that is thought to be involved in the development of cervical cancer. It is well-known that E7 stimulates tumour development by inactivating pRb. However, this alone cannot explain the various characteristics acquired by HPV infection. Therefore, we examined other molecules that could help explain the acquired cancer properties during E7-induced cancer development. Using the yeast two-hybrid (Y2H) method, we found that the Elk-1 factor, which is crucial for cell proliferation, invasion, cell survival, anti-apoptotic activity, and cancer development, binds to the E7. By determining which part of E7 binds to which domain of Elk-1 using the Y2H method, it was found that CR2 and CR3 of the E7 and parts 1–206, including the ETS-DNA domain of Elk-1, interact with each other. As a result of their interaction, the transcriptional activity of Elk-1 was increased, thereby increasing the expression of target genes EGR-1, c-fos, and E2F. Additionally, the colony forming assay revealed that overexpression of Elk-1 and E7 promotes C33A cell proliferation. We expect that the discovery of a novel E7 function as an Elk-1 activator could help explain whether the E7 has novel oncogenic activities in addition to p53 inactivation. We also expect that it will offer new methods for developing improved strategies for cervical cancer treatment.

Some sexual differentiation disorders are associated with gonadal neoplasia and increased incidence of testicular tumors has been discribed in the patients with, XY gonadal dysgenesis. The incidence of testicular tumors in infants and children are rare, representing only 1% of all pediatric solid tumors. In general, gonadal stromal tumors are one of the most characteristic endocrine tumors of the testis, endocrine activity occurs in at least 10-20%, among them Leydig cell tumors and Sertoli cell tumors are clinically important. Although the exact pathogenesis is unknown, endocrine activity due to estrogen secretion can be manifested clinically with gynecomastia or precocious puberty. We experienced and reported a child who visited for sexual precocity and had XY gonadal dysgenesis with Sertoli cell tumor.

Van Wyk-Grumbach Syndrome is an advanced sexual development in association with primary hypothyroidism. The clinical feature in this syndrome is more consistent with stimulation of the FSH receptor by the markedly elevated TSH levels. Treatment of the hypothyroidism results in a rapid return to normal of the biochemical and clinical manifestations. We experienced a case of Van Wyk-Grumbach Syndrome and report with the brief review of related literature.

Actinomycosis, in which the principal causative agent in man is known to Actinomyces israelii, is a chronic, suppurative diseases characterized by extensive fibrosis, multiple abscesses, and formation of sinus tracts that drain suppurative exudates. On the basis of the anatomical sites involved; it can be subclassified into the cervicofacial form, which is the most common form, pulmonary form and abdominal form. Kidneys are rarely affected. Clinically, radiologically, and at operation it is difficult to differentiate the renal actinomycosis from renal tuberculosis and renal carcinoma. The prognosis is excellent after nephrectomy followed by appropriate antibiotic therapy. We presented a case of renal actinomycosis with a brief review of the literatures.
