PURPOSE: Differential diagnosis of sexual precocity is important. Sexual precocity, defined as the appearance of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys, was studied to evaluate the sex incidence and etiology of sexual precocity. METHODS: We reviewed the etiology and age incidence of precocious puberty in 14 boys and 89 girls examined between 1994. 11. 1-2002. 7. 31 at Samsung Seoul Hospital. All underwent standard anthropometric measures. They were assigned to diagnostic categories on the basis of clinical assessment, endocrine evaluation, radiologic imaging, and pelvic ultrasonography. RESULTS: In 89 girls, 27 had idiopathic precocious puberty, 3 had precocious puberty with organic brain lesion, 12 had gonadotropin-independent precocious puberty, 44 had premature thelarche, 2 had premature menarche, 1 had premature adrenarche. The majority of idiopathic precocious puberty girls(78%) were aged between 7-7.9 years. In 14 boys, 2 had idiopathic precocious puberty, 3 had precocious puberty with organic brain lesion, 6 had gonadotropin-independent precocious puberty, 3 had gynecomastia. CONCLUSION: Sexual precocity occurs more frequently in girls than boys. Premature thelarche is the most common form of sexual precosity. In boys, majority of central precocious puberty had organic brain lesion, so brain imaging study should be performed. In girls, majority of idiopathic precocious puberty were aged between 7-7.9 years. Reexamination of the age limit for defining when puberty should be considered precocious in Korean girls is necessary.

2.The Effect of Histoacryl(R) for Gastric Variceal Bleeding Which Failed by Ethanolamine Oleate Injection Sclerotherapy.
Korean Journal of Gastrointestinal Endoscopy 1995;15(1):27-32
Treatment modalities of gastric variceal bleeding are endoscopic injection sclerotherapy, endoscopic variceal ligation, combined above two method, operation, TIPS, and percutaneous transhepatic embolization. Recently, Histoacryl was introduced as a new sclerosant of acute variceal bleeding failed by others. So, we studied 18 cases of acute gastric variceal bleeding uncontrolled by EIS using Ethanolamine oleate. Intravariceal injection of Histoacryl is considered as a safe and effective method for hemostasis of intractable acute gastric variceal bleeding uncontrolled by other sclerosants. But, it is important that endoscopist should be in harmony with assistant at injection of Histoacryl. And its shooting speed should be fast because of clogging within the catheter. It is necessary to do long term study for evaluation of eradication effect in acute gastric variceal bleeding.

The purpose of this study was to investigate the causes of food impaction and to explore solutions as well. For this study, 39 patients with food impaction wee selected. 77 contact areas in these patients were investigated mobility, tightness of contact area, gingival index, plaque index, attachment loss, alveolar bone loss, proximal caries, marginal ridge distance and occlusal relationships. The results were as follows ; 1. Teeth without distal support were found to be the most frequent site of food impaction (41.6%). Food impaction was found to be more frequent in the upper teeth (66.2%) than the lower teeth (33.8%). 2. Food impaction was found in tight contact cases (71.4%). Alveolar bone loss was not found in the early stage of food impaction (83.1%) 3. The distance between the marginal ridges of food impaction sites (mean=0.48mm) was shorter than that of the control group. (mean=0.77mm) (p<0.001) 4. In 18.2% of t he cases, proximal carries were found at the food impaction site. 5. Food impaction affected patient's occlusion with the following frequencies ; cusp to marginal ridge relationship (72.7%), cusp to fossa relationship (3.9%) and stepped relationship (23.4%).

PURPOSE: To understand natural course of transient hyperthyrotropinemia, so that the unnecessary treatment could be avoided. METHODS: Total 182 healthy newborns whose TSH levels in newborn screening test had been higher than 20 microIU/mL were recalled. Their serum levels of TSH, T4, free T4 were checked. RESULTS: Among 182 newborns, 10 newborns had congenital hypothyroidism. 68.1 % of healthy newborns who had high TSH levels were normalized within 2 months and all of the rests were normalized within 5 months. CONCLUSION: Transient hyperthyrotropinemia in newborns improves spontaneously. The unnecessary treatment of transient hyperthyrotropinemia should be avoided.

Ulcerative colitis is a chronic, inflammatory disease of colon which is rare in Korea. In the course of ulcerative colitis numerous extraintestinal complication may develop on the joints, skin, liver, kidney, vessel, oral cavity and eyes. The most common ocular lesions complicated in patients with ulcerative colitis are episcleritis and iritis. And the cases of retinal vascular disease in associated with ulcerative colitis are extremely rare. We experienced nonischemic central retinal vein occlusion complicated in a patient with ulcerative colitis, who is 32-year-old male and complained decreased visual acuity and metamorphosis.

Purpose: The results of a more than 10-year follow-up after total hip arthroplasties with circumferential and proximal porous-coated femoral stems were evaluated. Materials and Methods: Seventy-six patients (80 hips), who were operated on between Aug. 1991 and July 1994, were followed for more than 10 years after primary total hip arthroplasties using Multilock stems. The mean age at the time of the operations was 47.3 years old and the mean duration of follow-up was 12.3 years. The clinical results and radiological findings were evaluated. Results: The mean Harris hip scores improved from 54.7 points to 88.5 points at the time of the 10-year follow up. On the last follow-up radiograph, endosteal bone formation was observed in 70 hips (90%) and all femoral stems were biologically stable. Femoral osteolysis, which was linear in Gruen zone I and VII and mostly restricted to the proximal zones, was observed in 67 hips (84%), and no hip had distal osteolysis in the femur. There was no loosening, migration, or revisions of the stems. Conclusion: Total hip arthroplasties using circumferential and proximal porous coated Multilock femoral stems demonstrated stable osseous fixation and no distal osteolysis for a minimum 10-year follow-up; therefore, all stems were reported to have satisfactory outcomes. With improvement of cup design and liner wear, circumferential and proximal porous coating designs of femoral stems can be an alternative answer to mechanical failure due to aseptic loosening.

It is well known that fractures around the knee joint are usually combined with ligament injuries but it is easy to miss the ligament injuries during the treatment of fractures. The invention of the MRI and the development of arthroscopic techniques has made it easy to diagnose and care for ligament injuries. Authors reviewed the patients who had fractures around the knee joint to evaluate the frequencies, types, treatments and the results of combined ligaments injuries. There were 57 cases with the fracture of the proximal tibia and fibula which could be follwed up at least one year: from January 1992 to June 1995. There were 19 cases (33%) which had combined ligament injuries. The ligament injuries were diagnosed by stress X-ray & MRI evaluation and confirmed by arthroscopic examination. Single lateral rim avulsion fracture of proximal tibia was the most common type of fractures (7 cases, 37%). There were 11 cases (57%) of combined injuries of anterior cruciate ligament and medial collateral ligament. It was the most common combined ligament injury. Except for one, eleven cases that were combined with lateral rim avulsion of proximal tibia had anterior cruciate ligament injury. There were ten cases (53%) of fibula head and neck fractures which were combined with ligament injuries. The total number of the injured ligament was 35 and the common rupture sites of the injured ligaments was the attachment site of femur (13 cases) and tibia (16 cases). There were seven meniscal injury cases (37%). The interval from injury to operation averaged 14.1 days because many cases were acute injuries. Primary repairs for ruptured ligament were done in 31 cases (88%) because of their attachment site injuries. There were no instabilities except one case which was treated with posterior cruciate ligament reconstruction using semitendinosus ligament. It had a grade I posterior instability at the last follow-up. Early diagnosis and proper treatment on the ruptured ligaments and the torn meniscus combined with proximal tibia and fibular fractures seem to be important for a good prognosis.
