Proximal femoral focal deficiency (PFFD) in early infancy is characteristic by quite shortening of the tight segment, flexed, abducted and externally rotated position In assciation with a stable hip which Is freely mobile. Authors experienced a case with the congenital deficiency of the femoral head. The case showed the normal femoral segment and no any other bony anomalies which cannot be Included in Aitkens or Amstutz's classification.

Intraspinal tumors in children are of especially interest to orthopaedic surgeons for two reasons; First, musculoskeletal abnormalities, are often treated for long periods before the correct diagnosls is suspected; Second, important orthopaedic problems are encountered in almost everychild treated for intraspinal tumor, not only during the immediate postoperative management but all through subsequent growth. We report a case presentation of the intraspinai tumor, dermoid cyst, successfully treated with operation.

The methods of reconstruction for chronic Iigamentous instability of the knee have changed much since the concept of rotary instability was introduced by Slocum and Larson in 1968. The first step to successful management of these probrams is the accurate dlagnosis of the type or types of the instability that exist. Appropriate operative procedures should then be selected according to the type and degree of the instability as well as the age, general conditlon and the function demand of the patient. The stability can be restored passively by a near anatomical. repair of the injured ligaments, and can be reinforced actively by a proper muscle or tendon transplantation, such as the five-one procedure for anteromedial rotary instability. Nineteen knees of active, well motivated patients were operated on for chronic knee instabilities according to these new concepts. Although the follow-up period was relatively short, the results of the procedures was generally satisfactory.

During a 12-month period high-resolution, real-time ultrasonography (US) with graded compression was performed on 268 consecutive patients with clinically suspected acute appendicitis and its complication. US visualization of a fluid-filled, non-compressed appendix or a decompressed, thick-walled appendix was the primary criterion for a diagnosis of acute appendicitis. The sonographic findings were correlated with surgical-pathologic outcome in 92 cases and with the findings of clinical follow-up in the remainder. US was found to be accurate in the diagnosis of acute appendicitis and its complication with a sensitivity of 93.3%, a specificity of 98.9%, and an accuracy of 97%. The predictive value of a positive test was 97.7%; that of a negative test was 96.7%. There were two false-positive examination in patients with a thick-walled appendix or periapperdiceal abscess, which were surgically confirmed as appendiceal adenocarcinoma and perforated cecal diverticulitis respectively. There were six false-negative examination in patients with a sonographically no-visible appendix, which were confirmed surgically as acute appendicitis(n=5) and perforated appendicitis(n=1). Our results show that high-resolution, real-time US is an accureate imaging modality in the diagnosis of acute appendicitis and the evaluation of its complication.

Klippel-Feil syndrome is characterized by congenital fusion of cervical vertebrae with a wide range of associated anomaly. The authors present a 50-year-old Klippel-Feil syndrome patient with a minor trauma followed progressive quadriparesis. He had typical radiologic findings of type II Klippel-Feil syndrome and presented progressive myelopathy due to cord compression at foramen magnum level with cervical instability. The patient underwent craniocervical decompression and fusion. The authors reviewed the pertinent literatures and discussed this rare syndrome.

BACKGROUND AND OBJECTIVES: The efficiency of second harmonic generation at 532 nm is high when a pulsed Nd : YAG laseris used as a pump source of fundamental waves. The pulse durations of 532 nm-irradiation can be varied from 10 ns to 1000 ns by changing the pumping method. The purpose of this study was to compare the macroscopic and micropscopic changes in the muscle and skin after irradiation by 532 nm Flash lamp pumped solid state (FPSS) laser and Diode pumped solid state (DPSS) laser, whose pulse durations are 600 ns and 100 ns, respectively. MATERIALS AND METHOD: Two experiments were conducted on the muscle and skin of guinea pig. First, the guinea pig muscle and skin were irradiated by the 532 nm FPSS and DPSS lasers with various intensities and time duration. Macroscopic examinations were performed on the muscle lesions and immediate histopathologic examinations on the skin were carried out. RESULTS: The volume of vaporization and necrosis of the guinea pig muscle by the FPSS laser was larger than that by the DPSS laser. The vaporization and necrosis reaction of skin by the FPSS was significantly stronger than that by the DPSS laser. CONCLUSION: It appears that the DPSS laser system would be superior over the FPSS laser system in providing more accurate and precise surgery with less intense injury on the surrounding tissue.

PURPOSE: This study aimed to evaluate the status of renal function and the presence of urinary abnormalities in early adult patients with Turner syndrome (TS). METHODS: Sixty-three girls with TS, who are attending pediatric endocrine clinics in Busan Paik Hosp., were studied. Urine and blood chemistry tests were performed in every visiting times. Renal ultrasonography was performed in all patients at the initial diagnosis, and intravenous pyelography, DMSA renal scan and renal CT were also performed, if necessary. RESULTS: Of the 63 patients, the karyotype showed 45,X in 32 (50.8%) , mosaicism in 22 (34.9%) and structural aberration in 9 (14.3%). The renal function at the latest visit was shown as normal in all patients. Nephrotic syndrome had developed in one patient. Hematuria was observed in seven patients. Renal anomalies were observed in 20 of the 63 TS (31.7%). Of the 32 TS patients with 45,X karyotype, 13 (40.6%) had renal anomalies, while these were found in 7 (22.6%) of 31 TS patients with mosaicism/structural aberration. But there was no significant statistical difference between two karyotype groups. CONCLUSION: Based on this study, most of the patients with TS do not have any significant problems related to renal function until early adulthood, regardless of renal malformation or hematuria.

Chronic acquired hepatocerebral degeneration (CAHD) is a progressive or episodic neurologic syndrome that occurs occasionally in patients who have chronic liver disease or portocaval shunt. The clinical features of CAHD include action and postural tremors, generalized chorea, asterixis, myoclonus, dystonia, resting tremor, gait ataxia, and variable impairments of intellectual function. We experienced 2 cases of CAHD with unusual neurologic manifestations, which were hypokinetic parkinsonian symptoms. Both cases had a history of liver cirrhosis and the same symptoms. They had masked faces, cogwheel rigidiy in both wrists, slurred speech, tongue tremor, bradykinesia, and gait ataxia. They had normal mental status and no pathologic reflex. Brain MRI showed abnormal, increased signal on T1-weighted images in the globus pallidus and mesencephalon bilaterally. The hypokinetic parkinsonian symptoms disappeared when given doses levodopa.

Mediastinal parathyroid cyst is a very rare disease and is usually found incidentally. Surgical excision is the treatment of choice and recurrence is very rare when complete excision is done. A 71-year-old man was referred to our department because of 6x5cm sized right superior mediastinal mass found incidentally on chest X-ray. Surgical excision was performed and pathologic findings were confirmed as mediastinal parathyroid cyst. The patient has been followed up postoperatively without recurrence for 4 months up to now. We report a case of mediastinal parathyroid cyst.
