The pinching motion is thought to be one of fundamental hand functions, the power of which has been quantified by measuring it isometrically with variously devised pinch-meters. The present authors describe the investigations on the pinching power of 350 healthy persons, 200 male and 150 female Koreans, by the use of Preston Pinch Gauge. Six kinds of pinch were chosen: (1) thumb index finger tip pinch (1-2TP), (2) thumb-middle finger tip pinch (1-3TP), (3) thumb-index finger pulp pinch (1-2PP), (4) thumb-middle finger pulp pinch (1-3PP), (5) thumb-index-middle finger pulp pinch (3PP), (6) key pinch (KP), which were classified again into 19 kinds according to the shape of thumb, index, middle, or other fingers during each pinch. We describe those as principal type, hyperextension-flexion type, hyperextension type and other type into four. It should be justified to calculate the mean normal value of principal type pinching power in Korean. Principal type of pinch involves 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP, as to Hyperextension type of 1-2PP, 1-3PP, 3PP and KP. Other type of pinch involving 1-2TP, 1-3TP, 1-2PP, 1-3PP, 3PP and KP is different from Principal type simply because of the shape of nonjoining fingers during pinch. Generally, the pinching power of Principal type was clearly highest among the four types except for pulp pinches.

Nevoid basal cell carcinoma syndrome (NBCC syndrome) is a very rare autosomal dominant dermatopathy characterized by a primary triad with variable secondary anomalies. The chief features include nevoid basal cell carcinomas, one or more skeletal anomalies, and multiple odontogenic keratocysts of the jaw. We report a case of NBCC syndrome in a 43-year old male who had multiple nevoid basal cell carcinomas on the retroauricular area, face, chest wall, and back, which have been present since childhood. Skull x-rays revealed relatively well-circumscribed cystic, radiolucent lesions on bilateral rami of both upper and lower jaws, calcification of the falx cerebri, agenesis of the right coronoid process, and a bifid chin. The cystic lesions were histologically confirmed as keratocysts.

PURPOSE: To determine the long-term follow-up CT findings of paraquat-induced lung injury. MATERIALS AND METHODS: Six patients who ingested paraquat underwent sequential follow-up CT scanning during a period of at least six months, and the results were analysed. Scans were obtained 1-6 (mean, 3.3) time during a 7-84 (mean, 25.7) months period, and the findings at 1-2 months, 3-12 months, 1-2 years, 2-3 years, and more than above 7 years after poisoning were analyzed. RESULTS: We observed irregular-shaped areas of consolidation with traction bronchiectasis at 1-2 months (5/5), irregular-shaped consolidation and ground-glass opacity (5/5) at 3-12 months, and irregular-shaped consolidations/ ground-glass opacity (4/5) and focal honeycombing (1/5) one year later. In the same patients, follow-up CT scans showed that some areas of focal consolidation could not be visualized and the radio-opacity of the lesions had decreased. CONCLUSION: The HRCT findings of paraquat-induced lung injury were irregular shaped areas of consolidation 1-2 months after ingestion, and irregular-shaped consolidation and ground-glass opacity or focal honeycombing 3-12 months later. At this thim slight improvement was observed.

Malignant small cell tumor(MSCT) of the thoracopulmonary region(Askin tumor) is extremely rare and is seen predominantly in children and adolescents. This tumor represents a distinct clinicopathologic entity of neuroectodertnal origin, arising from the soft tissues of the chest wall or peripheral lung. This tumor tends to recur locally, but does not seem to disseminate widely. The overall survival is poor. Recently, we experienced a case of the MSCT of the thoracopulmonary region of a 12-year-old female. She was admitted because of a chest wall mass on radiographic examination, and a complaint of intermittent chest pain. Grossly, the mass was lobulated, round and had a solid appearance with focal necrosis and hemorrhage on the cut surface. Histologically, small round to oval cells were arranged in compact sheets, nests and lobular patterns with intervening fibrovascular stroma. Ultrastructurally, the presence of loose-fitting membrane-bound neurosecretory granules was noted.

Bcl-2 is a proto-oncogene initially described in follicular lymphoma, associated with chromosomal translocation(14;18). Recent studies have shown the presence of Bcl-2 in nonhematolymphoid tissue, especially in hormonally responsive tissue. The endometrium is an attractive model for studying the hormone dependent regulation of Bcl-2 expression. We have studied the immunoreactivity of Bcl-2 oncoprotein in relation to the immunoreactivity of estrogen receptors(ER) and progesterone receptors(PR) by immunohistochemistry in 52 human endometrial carcinomas, according to nuclear grade. The results obtained are summarized as followings, 1) Immunohistochemical grade of Bcl-2 showed a significant inverse correlation with nuclear grade. 2) Immunohistochemical grades of ER and PR also showed a significant inverse correlation with nuclear grade, and were well correlated with each other. 3) Immunohistochemical grades of Bcl-2 and hormone receptors showed a strongly significant correlation. On the basis of the above results, we suggest that Bcl-2 expression may be under hormone dependent control and that it can be used in prognosis and choice of hormonal therapy in the presence of hormone receptor.

Eight patients with diffuse panbronchiolitis were evaluated with chest radiograph and high-resolution computed tomography(HRCT). Paients consisted of 5 med and 3 women, aged 27-75 years(average, 54 years). Chest radiographic findings were diffuse small nodular densities, linear shadows, and thickened bronchial wall predominantly in both lower lung fields. All 8 patients had pansinusitis. On HRCT, small nodules and branching linear structures, 1-3mm internal to the pleural surface, representing centrilobular bronchiolar lesion, were found along with thickening of medium and small sized bronchial wall. These nodules did not show coalescence. In conclusion, chest radiographs were usually suggestive and high-resolution CT was diagnostic of diffuse panbronchiolitis.
