BACKGROUND: Pachydermoperiostosis(PDP) is a rare genetic disease characterized by pachydermia, periostosis, arthralgia and finger clubbing. The pathogenesis of this disease is still unknown, but the concept that platelets and endothelial cells may play a major role in the developement of pachydermia is widely accepted nowadays, It is also suspected that several serum growth factors stimulate proliferation of soft tissue. OBJECTIVE: The purpose of this study was to investigate the pathogenesis of pachydermia in patients with pachydermoperiostosis through evaluating whether the fibroblasts from these patients have a higher proliferation rate than those from controls or whether the proliferation rate of those cells are affected by certain serum growth factors. METHOD: At first, we evaluated the proliferation rate of fibroblasts from patients and corntrols by the MTT colorimetric assay, and then the proliferation rate of fibroblasts from the prepuce of newborn infants under several conditions of media containing uncentrifuged patients serum, centrifuged patients serum, uncentrifuged control serum, or centrifuged control serum. RESULTS: The proliferation of fibroblasts from patients skin was slower than the control fibroblasts and fibroblasts derived from uninvolved skin of patients. The statistically significant highest proliferation rate was observed when fibroblasts were cultured in the uncentrifuged patients serum contained media and the order of proliferation was as follows: centrifuged patients serum, uncentrifuged control serum and centrifuged control serum condition at 20%, 10%, and 1% respectively. CONCLUSION: These results suggest that patients fibroblasts do not proliferate in vitro at a higher rate than control firoblasts. Fibroblasts in PDP may only play a role as target cells and certain serum factors are responsible for the pathogenesis of PDP.

We performed a clinicopathological study of nineteen patients with chronic inflammatory nodose lesions of the legs which responded to the treatment with isolniazid. The results were summarized as follows: 1. Seven patients had a personal or family history of tuberculcsis and all patients showed a high tuberculin sensitivity. But, no one showed the evidence of active pulmonary tuberculosis. 2. The inflammatory nodules and swelling of the legs were resolved within 12 months in all cases. Resolution of the nodules was more rapid than that of leg swelling. 3. The clinical characteristics of the patients with chronic inflanimatory nodules were the same as those of the cases with erythema nodosum or erytiema induratum reported previously in Korea. The basic histopathologic process of inflarr matory nodules seemed to be vasculitis.

The authors treated 12 patients with pseudophakic endophthalmitis over a 5 year period between 1990 and 1994. Common clinical manifestations included anterior chamber inflammation, conjunctival injection, decreased visual acuity, ocular pain and hypopyon. Eight of 12 cases(67%) were culture positive when organisms were grown up from aspirates of the aqueous, the vitreous or both. Three of the culture positive cases were grown up from aspirates of the aqueous, the vitreous or both. Three of the culture positive cases were candida endophthalmitis. Treatment consisted of topical, periocular, systemic and intravitreal injection of antimicrobial agents. In addition, because of poor clinical response of medical conservative therapy, six cases had a vitrectomy. Intraocular lenses were removed in 3 candida endophthalmitis at second operation. Final visual acuity has better in culture negative and low virulent bacterial endophthalimitis than high virulent bacterial and candida endophthalmitis. Visual outcome was better in cured patients who received a single intravitreal injection or a single intravitreal injection in combination with virectomy than the patients who did not receive intravitreal injection or received repeated intravitreal injection. Complications were two eviscerations and a retinal detachment.

PURPOSE: There was no controlled study on botox injection and neurectomy for treatments of muscle hypertrophy. Although many studies have shown the clinical effects of each treatment, it was not able to evaluate and compare the effects of each treatment because there was no comparison of the two treatments under the same experimental condition. Hence, the aim of this study is to com METHODS: The study was carried out on 21 rabbits. 9 rabbits received botox injection(botox injection group), and neurectomy was performed to another 9 rabbits (neurectomy group). 3 rabbits did not receive any treatment(control group). To compare and analyze the effects of muscular atrophy, muscle was stained with NADH-TR, and the changes in size of the muscle fiber were examined. And the electromyography was examined. In each group, muscle fiber was stained and electromyography was performed 2, 3, and 6 months after injection or operation. RESULTS: In histological test and electromyography, in the neurectomy group, the size of muscular fiber and amplitude of electromyography decreased until 2 months after neurectomy. And decreased results were maintained with the passage of time. It showed irreversible aspect. On the other hand, in the botox injection group, the decrease in the size of muscular fiber and amplitude of electromyography was observed until 2 months after injection. In 3 months after the injection, it was slowly getting back to original size and had almost recovered by 6 months after the injection. It showed reversible aspect. CONCLUSION: This study shows researches about clinical effect of botox injection and neurectomy coincide with the results of experiment under the same experimental condition.

Maffucci's syndrome is a very rare, congenital and non-hereditary mesodermal dysplasia manifested by multiple enchondromas and soft tissue hemangiomas. Since Maffucci had reported this sysdrome in 1881, there have been more than 100 cases reported, and also there has been reported that Maffuddi's syndrome has various interstitial tumor. However there hasn't been any report about Maffucci's syndrome with testicular teratoma. Here we report in this paper that the patient was diagnosed as Maffucci's syndrome of enchondroma and liver hamangioma and also had testicular teratoma. He was admitted for the evaluation of gynecomatia and diagnosed as enchondroma by bone biopsy of the right rib and tibia. Liver hemangioma was also found through abdominal ultrasonogram, CT scan and liver biopsy. And the testicular teratoma was confirmed through testicular biopsy. He is finally diagnosed as Maffucci's syndrome with testicular teratoma and literatures were reviewed.

In 1947, Ota et al. first reported a case of phakomatosis pigmentovascularis and defined a subgroup of this disease having a congenital generalized hemangioma and pigmented lesions including a mongolian spot-like lesion, nevus pigmentosus and nevus of Ota. We experienced a case of phakomatosis pigmentovasularis type IIb in a 10-day old male baby, who since birth, had generalized nevus flammeus and blue spots, syndactyly between 2nd and 3rd toes in both feet, and dilated collecting system in left kidney.

Surgical curettage or en bloc excision are the usual choice of treatment for osteoma. Local recurrence of osteoma after surgical treatment is not very common. We report a case of osteoma recurred at the grafted bone. A 5 x 8 cm sized osteoma of frontal bone was excised and then the defect was covered with calvarian bone and rib bone. Six years after reconstruction, recurrence from grafted area was noted. We completely removed the osteoma with enough normal tissue around it, after checking that the grafted bone has changed into an osteoma through a bicoronal incision. Then we covered the defect with a rib bone. The tissue was confirmed histologically as an osteoma. The recurrence of the tumor at the bone grafted site after osteoma excision is probably due to the fact that we covered grafted bone with periosteum left over osteoma. Therefore, we can learn that when we excise osteoma, galea should be carefully separated from the periphery of the tumor and that the periosteum should be completely removed, to prevent the osteoma from recurrence.

Fibrous dysplasia(FD) of the bone is a slowly progressive, benign disease of unknown cause where normal architectures are replaced with fibrous and osteoid tissue. FD of the maxilla usually manifests as a bony enlargement with painless swelling and bone deformity, contouring to facial asymmetry. The lesion may involve the nasal fossae, orbits, or alveolus bone, causing diverse functional disturbance. Treatment options range from shaving to total maxillectomy and reconstruction depending on the presenting symptoms. Shaving, partial maxillectomy and maxillary sinus formation was performed in 5 patients with fibrous dysplasia in the past 2 years. Follow up period ranged from 1 month to 11 months. Aesthetic appearance, CT findings, and relief from symptoms were compared. In all patients, facial asymmetry was restored to symmetry and nasal obstructive symptoms were improved. With this procedure, expansion of the lesion will be controlled until puberty, preventing the development of new functional disturbances. After puberty, no further treatment can be anticipated due to the growth arrest inherent to the disease.
