A case of pathological hip dislocation in a child, aged 2 years 6 months, who had surgical treatment, is reported. The boy has history of osteomyelitis of right ilium at age of 10 month, which ended up with the right hip dislocation. Postoperatively cephalocotyloid relation of the right hip was very well reestablished during five years of postoperative observation. Through this case, it is reconfirmed that a child hip has a natural remodelling power even in case of hip joint destruction.

Reduction of displaced diaphyseal fractures of the radius and ulna in adult must be nearly anatomical for restoration of mormal function. Most of the fractures require operative management, and various methods of open reduction and internal fixation have been recommended. Because we believe that anatomical reduction followed by rigid internal fixation provides the most satisfactory results for these injuries, dynamic compression plating method is frequently used in our hos pi tal. We studied 52 diaphyseal fractures of the forearm bone in 33 patients treated at the S.R.C.H. from May 1980 to December 1985. Of the 33 patients, 20 had fractures of the radius and ulna; 6, fractures of the radius only; and 7, fractures of the ulna only. The fractures of both bones were treated with plate and screws in 19 patients. In another one, the ulna was treated with plate and screws and the radius was treated by screw fixation only. The results were as follows: l. Of the 52 fractures, 51(98.1%) were united after the initial operation within 23 weeks. 2. The average time for radiological union of the fracture, excluding those complicated by infection or non-union, was 11.1 weeks for 24 radii and 10.9 weeks for 25 ulnae. 3. Only one patient(3.0%) was complicated by infection and only one(1.9%) non-union of radius occurred. 4. The functional results were excellent or satisfactory in 25 patients(83.3%). 5. We have found that in adults the auto compression plating is a successful method for the diaphyseal fractures of the forearm.

Magnetic resonance (MR) images of 14 consecutive patients with pathologically proven primary intracranial lymphoma were reviewed. All patients had a brain MR imaging before any treatment and were immunologically competent. MR images were acquired using 2.07 (n= 6) or 0.57 (n= 8) machine. The MR images were reviewed regarding the location, multiplicity, size, signal intensity, margin, shape, and the extent of surrounding edema of the lesion. Seven patients had multiple lesions, 2 to 4 in number. A total of 26 lesions was found; 25 were parenchymal lesions and one was dural lesion. The location of tumor was either central (r= 11) or peripheral (n= 14). The size of tumor was variable ranging from 0.6cm to 6.0cm in its maximal diameter. The tumors were isointense (n= 19) or hypointense (n= 7) relative to gray matter on T1-weighted images, isointense (n= 24) or hyperintense (n=2) on proton-density weighted images, and isointense (n= 21) or hyperintense (n= 5) on 78-weighted images. On gadolinium-enhanced T1-weighted images of 13 patients strong enhancement was seen in 22 of 23 lesions. Nineteen lesions showed smooth, well-defined margin, whereas remaining 7 lesions showed irregular, ill-defined margin. The shape of the tumor was diverse; round of ovoid (n= 15), lobulated (n= 9), or short linear (n= 2). These results suggest that one should consider the diagnosis of CNS lymphoma in cases with single or multiple masses that abut CSF space and show iso-or similar intensity to gray matter with strong enhancement on MR images.

Inhibin is a glycoprotein usually produced by granulosa cell of ovary and is known as regulator of FSH secretion. Inhibin is consisted of two heterodimeric subunit of a, B . There are two distinct molecular forms of the B subunit that exist (BA and BB) and when combined with an a subunit, form inhibin A, and inhibin B, respectively. Ovarian reserve describes women's reproductive potential, which usually decreased according to chronological age. Because useful markers claimed for the prediction of ovarian response during controlled ovarian hyperstimulation for IVF-ET have not been always successful, new biomarker has been investigated. The purpose of this study was to observe the changes in serum and ovarian follicular inhibin A concentration during controlled ovarian hyperstimulation for IVF-ET program and to evaluate the clinical significance of inhibin A as a prognostic marker for assisted reproductive technology outcomes. From Jan 1996 to Dec 1996, 48 patients who underwent IVF-ET were included. In each patient, the Day 3 FSH, LH, E2q were measured in the first month of cycle before commencing GnRH agonist administration, In the stimulation period after pituitary down regulation, blood samples for inhibin A were collected at the day 3, day 7, day of hCG injection, day of oocytes aspiration, and day of embryo transfer. Ovarian follicular inhibin A was collected at the day of oocyte aspiration. Inhibin A concentration was measured using test kit for inhibin A (INHIBIN-EASIA (code 40.134.00), Belgium Medgenix). The changes in serum inhibin A, E2 concentration during IVF-ET program showed increasing pattern throughout controlled ovarian hyperstimulation periods. If the cut-off value of day 3 serum inhibin A determined to 0.28 U/ml, the sensitivity and specificity were 80.0%, 75.0% respectively in predicting the number of oocytes retrieved being more than five. If the cut-off value of peak serum E determined to 1316 pg/ml, the sensitivity and specificity were 89.0%, 100.0% respectively in predicting the number of oocytes retrieved being more than five. In conclusion, measurement of serum inhibin A concentration on the day of starting stimulation (day 3) could be used as a useful marker for predicting the ovarian response in IVF-ET program.

The purpose of this study is to describe the magnetic resonance imaging (MR) findings of metastatic brain tumors with emphasis on the signal intensities of the lesion on MR. Thirty four patients with intracranial metastases were studies with MR imaging. The diagnosis was established on the basis of either brain biopsy or combination of brain MR findings and the presence of primary tumors. The primary tumors include lung cancer (n=18), breast cancer (n=3), stomach cancer (n=3), rectal cancer (n=1), renal cell carcinoma (n=1), hepatocellular carcinoma(n=1), ovarian cancer (n=1), thyroid cancer (n=1), melanoma (n=1) and unknown primary sites (n=4). The parenchymal lesions were solitary in 35% (12/34) and multiple in 65% (22/34). The size of the lesions was variable, ranging from several millimeters to 5cm in diameter. The corticomedullar junction of the cerebral heispheres was the most common location of the lesions (68%). The signal intensity of solid portion of the lesions was usually either isointense (44%) or hypointense (29%) on T1-weighted images, whereas it appeared in isointense (47%), hypointense (8%) or hyperintense (11%) on proton density-weighted or T2-weighted images. The remaining cases showed mixed signal intensities. The enhancement patterns were variable including nodular (<1cm) (6%), homogenous (19%), heterogeneous (10%), ring-like enhancement (22%) or mixed pattern(43%). The size of surrounding edema was larger than the tumor diameter in 76%. In conclusion, although there are no specific MR findings of intracranial metastasis except multiplicity, intracranial metastasis should be included in differential diagnosis with high priority, when a solitary mass showing isointensity on boty T1-and T2-weighted images with massive surrounding edema, especially in the corticomedullary junction of the cerebral hemispheres is encountered.
