Clubfoot or talipes equinovarus is the most common congenital anomaly of the foot observed in children as well as in adults. This deformity should be treated immediately after birth, and so the cases of old neglected clubfeet are quite rare now. Moreover, in the cases of old neglected clubfoot, it is very difficult to get satisfactory results because there will be secondary adaptive changes in the tarsal bones and surrounding soft tissues. Therefore, clubfeet are considered to be one of many things requiring on or more of the many different types of treatment. The authors have experienced to treat nine cases of old neglected clubfoot from May, 1978 to April, 1988 at the Department of Orthopedic Surgery, St. Mary's Hospital, and reported herewith. 1. Their average age was 14.8 years old (3 to 25 yesrs old). There were one bilateral clubfeet, left foot in 5 cases and right foot in 4 cases. 2. According to the age of the patients and severity of deformities, two patients from three to ten years old were treated with soft-tissue release and serial casting, and seven patients after ten years old were treated by soft-tissue release, various osteotomies and triple arthrodesis. Postoperative management consisted of long leg cast for first four weeks and short leg walking cast for another four to eight weeks. 3. The results were estimated by the talo-calcaneal index according to Beatson et al(3)radiologically and their external appearance of corrected foot subjectively. The talo-calcaneal index was improved from 17.8° to 37° after operation and all of patients satisfied with the results of their operation.

Acute generalized exanthematous pustulosis(AGEP) is a disease entity caused mostly by drugs or viral infections. Clinically it manifests as generalized erythema, erythema multiforme and amicrobial pustules with fever. Histologically, AGEP is composed of neutrophilic subcorneal and spongiform pustules. A 70-year-old female, with no personal or family history of psoriasis, was given medication including diltiazem for hypertension. Fourteen days after taking the medications, pustular eruptions appeared on the face and rapidly spread to the trunk and limbs. A Laboratory examination revealed neutrophilic leukocytosis and an elevated erythrocyte sedimentation rate. The skin biopsy showed subcorneal and spongiform pustules. We report here a case of AGEP probably due to diltiazem.

6.An Experimental Study of Osteoporosis Produced by Oophorectomy and /or Immobilization in Rats

Previous studies implied association of osteoporosis with estrogen deficiency, immobilization and low calcium absorption only through epidemiological studies. There have been only a few experimental studies verifying the etiologic factors of osteoporosis in vivo condition. Authors conducted an experimental study using white rats(Sprague Dawley) in order to find out what the endocrinological and biochemical changes of experimentally induced osteoporosis are and how they behave with or against each other. White rats, eighty five in number of 3 to 6 months females and weighing 220±12.7gm were divided into four groups. They consisted of Group I(n=10) for control, Group II(n=25) for bilateral oophorectomy, Group III(n=25) for bilateral division of sciatic nerve and hip spica cast immobilization, and Group IV(n=25) for bilateral oophorectomy and bilateral division of sciatic nerve plus hip spica cast immobilization. Blood samples were taken preoperatively and postoperatively at six weeks to check Estradiol and Osteocalcin levels there of. And then, rats were sacrified immediately after the second sampling to retrieve femora for bone mineral density measurement and torsional stress test. Estradiol levels before operation were 21.4±13.3pg/ml for Group I, 31.6±3.1pg/ml for Group II, 25.6±4.5pg/ml for Group III and 33.7±4.5pg/ml for Group IV, respectively. There were no significant differences observable among the groups. Estradiol levels at six weeks postoperatively were 42.3±18.8pg/ml for Group I, 5.4±2.7pg/ml for Group II, 40.8±5pg/ml for Group III and 6.2±2.3 pg/ml for Group IV, respectively. Apparent reductions in group II and IV were proved of statistical significance. Osteocalcin levels preoperatively were 1.2±0.6ng/ml for Group I, 1.7±0.4ng/ml for Group II, 1.5±0.1lng/ml for Group III and 1.5±0.1.lng/ml for Group IV, respectively. At six weeks postoperatively they were 1.6±0.1lng/ml for Group I, 1.7±0.3ng/ml for Group II, 1.8±0.3ng/ml for Group III and 1.2±0.1lng/ml for Group IV, respectively. The differences and changes among the groups and measurements were not of statistical significance. Bone mineral contents at six weeks postoperatively were 0.248±0.03g for Group I, 0.177±0.03g for Group II, 0.226±0.04g for Group III and 0.092±0.01g in Group IV, respectively. Low values of Group II and IV compared to those of Group I and III were of statistical significance.(P=0.0001) Torsional strength of bones at six weeks postoperatively were 4.0±0.2N/m for Group I, 1.5±0.1N/m for Group II, 1.5±0.1N/m for Group III and 1.4±0.1N/m for Group IV, respectively. Decreases of experimental groups(II, III, IV) compared to that of control group(I) were of statistical significance, but differences among the experimental groups were not of significance(p>0.05). For above observations, it was possible to conclude that osteoporosis measurable by bone mineral content and torsional stress test was caused by oophorectomy and immobilization in vivo, the former of which was more rapid and profound than the latter during early phase. When both factors, i.e., oophorectomy and immobilization are exerated simultaneously. the resultant osteoporosis was found in higher degree than either factor only, but not at incremental degree as one may expect.

7.A Case of Papulonecrotic Tuberculid.

The pathogeoesis of papulonecrotic tuberculid had been thought to be the result of hernatogenous dissemination from primary tuberculous focus of other organs. But, today, the existence of papulonecrotic tuberculid as a rare cutaneous reaction to the Mycobacterium bacillus is questioned. Papulonecrotic tuberculid is, however, a real entity in underdeveloped countries where tuberculosis is more common. We report a case having papulonecrotie tuberculid associated with cervical lymph node tuberculosis confirmed by typical histopathology and by clinical response to antituberculous chemotherapy. This case supports Iden et al's view (1) that skepticism regarding the existence of papulonecrotic tuberculid is probably the result of the current decreased prevalence of untreated tuberculosis and consequently increased rarity of this entity.

A 43-year-old woman presented with numerous cutaneous neurofibromas, limited to the left anterior chest(T2-3) and the right lower back(L1-2). These had been present for 10 years. Neither cafe-au-lait spot, intertriginous freckle, nor Lisch nodule was found. The family history was negative for neurofibromatosis. Biopsy specimens showed circumscribed, nonencapsulated neurofibromas. The present case was a rare form of bilateral segmental neurofibromatosis in that while most of the reported cases involved the same dermatome bilaterally, she had bilaterally different dermatomal neurofibromas.
