Pulmonary artery aneurysms are very rare. They are usually associated with congenital cardiac defect. We present one case of pulmonary artery aneurysm associated with patent ductus arterious with the review of the literatures.

There are many kinds of instrumentation systems for posterior operation in the treatment of scoliosis. Cotrel-Dubousset (C-D) system is most widly used for its excellent correction potential and stability. However there were some problems in C-D hook system such as hook dislodgement and correction loss. So, in order to reduce these problems we use transpedicular screw system and compare the results between two systems. We studied 44 cases of scoliosis ( hook 19 cases, screw 25 cases) who were operated with C-D instrumentation from February 1988 to August 1995. The average follow-up period was 54 months in hook group and 23 months in screw group. 1. Operation time was 241 minutes in hook group and 223 minutes in screw group. Average amount of transfusion was 5.0 pints in hook group and 4.6 pints in screw group. 2. Involved segments of main curvature were 7.0 in hook group and 6.6 in screw group. 3. Scoliotic curve was changed from 49degrees to 13degrees (73%) in hook group and from 47degrees to 12degrees (74%) in screw group. Loss of correction during follow up period was 7degrees in hook group and 3 in screw group. 4. Thoracic kyphosis was changed from 24degrees to 26degrees in hook group and from 27degrees to 30degrees in screw group. Lumbar lordosis was changed from 26degrees to 29degrees in hook group and from 26degrees to 31degrees in screw group. 5. Correction rate of rotation of apex vertebrae by Pedriolle method was 43% (from 20degrees to 12degrees) in hook group and 50% (from 22degrees to 11degrees) in screw group. 6. Complications were two cases of hook dislodgement, one delayed deep infection and four cases of progression of curvature in hook group and one case of malinsertion of screw and two cases of progression of curvature in screw group. In conclusion, these results suggested that screw system is more effective than hook system on rotational correction of apex vertebra and prevention of loss of correction.

Mandibular implant overdenture is a good treatment option for complete edentulous patients with restoring removable prosthesis. Mandibular implant overdenture with two implants and locator attachments is widely used. It is tissue-supported overdenture that is made with the concept of conventional complete denture fabrication. There are two patients who provided impressions by open mouth technique and closed mouth technique in each case. In both cases, mandibular implant overdentures were restored with functionally and aesthetically satisfying results.

Teratomas of the fallopian tube are extremely rare, and only about 50 cases have reported in the world literature. Most cases of mature cystic tubal teratoma are asymptomatic and are discovered as an incidental finding on physical or radiologic examination, or at the time of laparatomy. We report a case of mature cystic teratoma of the right fallopian tube which was discovered during pelvic ultrasonogram for antenatal care in a 28 year old woman. Right salpingectomy was performed during cesarean section for cephalo-pelvic distortion at IUP 39 weeks. Gross examination of the right fallopian tube reveals a distended fallopian tube, measuring 8cm in length and 2cm in diameter. On section, it is filled with several small pedunculated nodules and cysts containing sebaceous materials. Microscopically the tumor was seen in continuity with the lining epithelium of mucosal folds. The majority of the tumor was composed of well differentiated mature elements of three germ layers with skin and skin appendages, mature brain tissue, bone, breast tissue, intestinal mucosa and bronchial epithelium.

BACKGROUND: Epidural steroids injections are often used for the treatment of low back pain but their effects on the endocrine system have not been determined. Few studies have quantified the degree or duration of the suppression of the hypothalamic-pituitary-adrenal (HPA) axis in humans given epidural triamcinolone injection (ETI) for low back pain. The evaluation of the blood adrenocorticotropic hormone (ACTH) and cortisol was undertaken to determine the extent of suppression of the HPA axis in patients given ETI. METHODS: Lumbar epidural triamcinolone injections were performed on the painful lumbar intervertebral space with patients in the lateral decubitus position. The injection consisted of 40 mg of triamcinolone acetonide diluted in 10 mL of 1% lidocaine. Patients remained in the lateral position for 10 min after the procedure. Basal blood sampling was performed at 30 min before ETI and tested blood sampling was obtained at 7 days, 10 days, and 14 days after ETI. RESULTS: The blood cortisol level was significantly decreased at 7 days and 10 days but at 14 days was not significantly decreased and the blood ACTH level was not significantly decreased at 7 days, 10 days, and 14 days. CONCLUSIONS: Above results demonstrate that blood ACTH and cortisol level normalize 7 days and 14 days, respectively, after epidural triamcinolone 40 mg injection.

Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

Normal and abnormal follicular growth and steroidogenesis depend on gonadotropins as well as intraovarian peptides, which may mediate or potentiate gonadotropin action. Inhibin also affect follicular development and steroidogenesis and may play a role in dominant follicle selection and follicular atresia. Therefore, we studied the differences of serum inhibin, gonadotropin and androgen levels in the women with only the ultrasound findings and no disorder, and polycystic ovary (PCO) with ovulatory disturbance. We prospectively analysed forty-three women with PCO. The diagnosis of PCO was based on typical appearance of the ovaries on TVS. Twelve women with regular menstrual cycle and normal ovarian morphology were selected as control. Basal levels of inhibin, luteinizing hormone(LH), follicle stimulating hormone(FSH), estradiol(E2), testosterone(T), androstenedione(ADD), dehydroepiandrosterone-sulfate(DS), prolactin and TSH in serum were determined. There were significant differences in basal LH levels and LH/FSH ratio between the control and the women with PCO. The basal levels of inhibin and E2 in the oligo-amenorrheic PCO (N=34) were significantly higher than those in the control. There was higher negative correlation between the inhibin and T levels in the oligo-amenorrheic PCO, but, not in the regular cycling PCO. Also, there was higher positive correlation between the LH and T levels in the oligo-amenorrheic PCO, but not in the regular cycling PCO. These data presume that the initial event of PCO is elevated pituitary LH secretion. Elevated levels of LH may down-regulate LH receptors on granulosa cells and also cause hypertrophy of the thecal layer. High level of androgen secreted by the hypertrophied thermal layer may stimulate inhibin secretion from granulosa cells and can be converted to estrogen by extraovarian tissues and could serve to augment pituitary sensitivity to GnRH with a resultant secretion of more LH follicular development and dominant follicle selection resulted in ovulatory disturbance.
