Fractures of the neck of the femur have always presented great challenges to orthopedic surgeons and still remain as one of the unsolved fracture as far as treatment and results are concerned. With life expectancy increasing with each decade, becoming more and more patients suffering from femoral neck fractures and their sequelae. The objoct of this study is to observe the relationship between the clinical results and the degree of displacement of fracture, degree of osteoporosis and duration between injury and operation in femoral neck fractures treated with multiple pin fixation. The author clinically analyzed 56 patients of the femoral neck fractures treated with closed reduction and multiple Knowles pinning followed by more than 1 year at Korea University Hospital from January 1986 to December 1991. There were 20 male and 36 female. The age of patients were ranged from 32 to 88 years(average:65.1 years) and most commonly occurred in 7th decade (23cases,41%). The most common cause was slip down(44 cases;79%). The most common type of fracture was stage III (48%) following to Gardens classification. The obtained results were as follows; 1. Union occurred in 49 cases(88%). 2. Among fifty-six cases, five cases(9%) of avascular necrosis, two cases(4%) Of non-union, two cases(4%) of malunion and one case of posttraumatic arthritis were occurred. 3. The functional results by Lunceford criteria were excellent in 30 cases(53% ), good in 13 cases(23%), fair in 5 cases(10%) and poor in 8 cases(14%). 4. Unsatisfactory results were noted in Garden stage II or IV, osteoporosis below Singh index 3 and delayed treatment over 1 week. Above results suggest that multiple Knowles pinning in femoral neck fractures offers high union rate and low complication rate, and so is also one of salvaging method of femoral head.

Hair takes a great role in featuring man's appearance and absence of hair can causes troubles in physical and psychological aspects. Many efforts have been made to treat male pattern baldness, including medical therapy and surgical correction, but there is not a definite and eternal method of treatment. Even though the diagnosis of male pattern baldness can be made with its characteristic clinical manifestations, histopathological study must be done for definite diagnosis. Author obtained biopsy material from the frontal progressive baldness area and the occipital non-baldness area with punch biopsy in 20 patients who were diagnosed to be Type II and III male pattern baldness according to the Norwood classification. A comparative study was done in the basis of histopathology using serial vertical section of the biopsy materia with the aid of light microscope and the results are as follows : 1. The average number of total hair in the frontal area was on third than that of occipital area and the number of anagen hair was less in the frontal area. The number of telogen hair in the frontal area was seven times more than that of occipital area. 2. The thickness of epidermis and dermis in the frontal area was thinner than that of occipital area. 3. The infiltration of inflammatory cells in the periadnexal field like blood vessels, hair follicles, sebaceous glands, eccrine glands was more prominent in the frontal area than in the occipatal area. 4. Perifollicular fibrosis and hypertrophy of arrector pilli muscle were more remarkable in the frontal area compared with that of occipital area. 5. There was no difference between the frontal and occipiral area in the number of lobules of sebaceous glands.

Dyschromatosis universalis hereditaria was reported in 1933 by Ichikawa and Hiraga in Japan. This disease is characterized by small pigmented and depigmented mottled macules on the trunk and extremities. We report two cases of dyschromatosis universalis. Case one is a 47-year-old man presented with hypoand hyperpigmented spots on the trunk and extrexities. At about 30 years of age, he started to show pigmentary changes on the back, which became progressively spread to the other parts of the trunk and extremities. Case two is a 27-year-old man with numerous mottled hypo-and hyperpigmented spots on the trunk and extremities. He started to show pigmentary changes on the back about 12 years ago. This pigmentary changes also became progressively spread to the other part of the trunk and extrimities. There were no family history of similar disease. On physical exminations, both patients had hrown rice-grain sized pigmented and depigmented macules without scales and atropy on the trunk and extremites. Fontana-Masson stains revealed decreased and increased melar in granules in the basal cell layers in the hypopigrnented and hyperpigmented lesions respectively.

Idiopathic progressive atrophoderma of Pasini and Pierini(IPAPP) is charcterized by sharply dermatcated, atrophic and slate-gray to brownish patches. We report a 17-year-old female with well-defined, atrophic, and brown colored patched on the abdomen, flank, and back. Histologic finding showed marked thining of dermis with thichening of collagen fibers and fragmentation of elastic fibers.

Retinal vein occlusion(RVO)is the second most common form of retinal vascular disease next to diabetic retinopathy. Systemic risk factors such as hypertension, diabetes, cardiovascular disease, blood dyscrasia and ocular risk factors such as short axial length, glaucoma, papilledema, thyroid ophthalmopathy have been shown to be associated with RVO. It is usually unilateral disease, and bilateral occurrene of RVO is relatively uncommon. CRVO rarely occurs bilaterally with a short interval between two eyes. Having experienced a case of bilateral CRVO within one month in a 75-year-old female with short axial length, primary open angle glaucoma, hypertension and hypercholesterolemia, we report this case with literature review.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

Radiation therapy is used for the palliative treatment of malignant tumors and the radiation induced osteonecrosis is one of the well documented complications. Especially, in pelvic region, there are a few reports for osteonecrosis of the femoral head and acetabulum after the radiation therapy for the the malignant tumors such as cervical carcinoma or prostatic cancer. Roentgenographic changes that are caused by radiation include the rarefaction of bone and coarsening of the trabeculae. The radiolucencies tend to coalesce and patchy sclerosis appears. In acetabular region, this Pagetoid appearance mimics the findings of other malignant bone tumors, the recurrence of preexisting malignant peivic tumors and other infectious condition. After the diagnosis is confirmed, the treatment for the femoral head and acetabulum is also difficult. The authors report one case of osteonecrosis of the femoral head and acetabulum following radiation therapy which had many difficulties in its diagnosis and treatment.
