A nineteen year-old boy with progressive enlargement of the joints and distal extremities, clubbing, coarse facial features and hyperhidrosis was investigated. In physical examination, thickening of the scalp with furrowing (cutis verticis gyrata) and greasy thickening of skin (pachyderma) was prominent. His endocrine profile was normal. Radiological studies demonstrated bilateral symmetrical periosteal new bone formation with acroosteolysis and incidental microadenoma of pituitay gland. After extensive investigation to exclude systemic and endocrine causes, the patient was diagnosed as pachydermoperiostosis (PDP). PDP is a rare syndrome manifested clinically by finger clubbing, extremity enlargement, hypertrophic skin changes, and periosteal bone formation. The pathogenesis of the disorder has not been clarified though few endocrine abnormalities were seen. To aware of these clinical phenotype would help to differentiate PDP from acromegaly.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.

STUDY DESIGN: Thirty-eight patients with thoracolumbar spinal tuberculosis were evaluated according to the surgical treatment method, either a one or two stage anterior debridement, with anterior or posterior instrumentation, respectively. PURPOSE: The aim of this study was to compare the effects of the one stage anterior debridement, with anterior instrumentation, to the two stage anterior debridement, with posterior instrumentation MATERIALS AND METHODS: Thirty-eight patients, with tuberculous spine, were divided into two groups depending on the surgical method. One group consisted of 21 patients treated with anterior debridement combined with anterior instrumentation, and the other group consisted of 17 patients treated by a two stage operation of anterior debridement combined with posterior instrumentation. The clinical outcomes were evaluated from the hematological laboratory findings, bone union in radiographs, change of kyphotic angle, duration of hospital stay and the medical cost during hospitalization. RESULTS: There were no recurrences of infection in either group and bone union was obtained within 6 months of the operation for all cases in both groups. The preoperative, postoperative and final follow-up kyphotic angle in the two groups were 18/20, 7/9 and 10/11 degrees, respectively. There was no significant difference in the decrease of the kyphotic angle between the two groups (p>0.05). However, group I was superior to group II in relation to the duration of hospital stay and the medical cost. CONCLUSION: We concluded that the one stage operation was the better of the operative methods for the treatment of active tuberculous spondylitis in a thoracolumbar spine.

Retinotomy, cutting of the retina, can be helpful in hte management of giant retinal tears, subretinal strands, and retinal incarceration. Relaxing retinotomies are used in the presence of retinal shortening or fibrous proliferation and contraction, and usually performed in the peripheral or equatorial retina. To fascilitate retinal attachment, the authors used intraocular scissors to perform radial retinotomy in the macula of two patients during vitrectomy surgery. We obtained a successful result using retinotomy in the macula as an adjunct to repair of retinal detachment with macular hole formation.

PURPOSE: To evaluate the usefulness of spiral CT in predicting the depth of tumor invasion in patients with gastric cancer by comparing with histopathological finding. MATERIALS AND METHODS: We studied spiral CT scans of forty-eight patients, in whom gastric cancer was proven by gastrofibroscopic biopsy and surgery. After distending the stomach with 400ml tap water or effervescent granules, 100ml of contrast media was given intravenously at a rate of 3ml/sec. CT scanning was started at 45 sec after administration of the contrast material. Gastric tumors were subdivided into five types according to enhancing pattern from the inner layer of gastric wall to the outer layer. These pattern were correlated with histopathologic results. RESULT: The tumor masses were detected on CT scan in 10(77%) of 13 patients with early gastric cancer, while, the tumor masses were seen on CT scan in all patients with advanced gastric cancer. Of 9 patients with type 1 or type 2 enhancing pattern, early gastric cancer(T1) were proven in 7 patients(78%), serosal invasion (T3) in 2 patients(22%). In contrast, among 29 patients with type 4 and type 5, 22 patients(76%) were proven as serosal invasion(T3). Of 7 patients with type 3, 3 patients(43%) were proven as serosal invasion(T3), three(43%) as subserosal invasion(T2), one as early gastric cancer(T1). CONCLUSION: Analysis of morphological enhancing pattern on spiral CT is useful in predicting the depth of tumor invasion in patients with gastric cancer.

OBJECT: Object of this study is to study which factors affect the prognosis in spontaneous thalamic hemorrhage treated with conservative method, stereotactic surgery and extraventricular drainage. MATERIAL AND METHODS: We analyzed 127 patients with spontaneous thalamic hemorrhage for evaluating the factors affecting prognosis. Various factors such as age, sex, location of hematoma, Glasgow coma scale(GCS) on admission, intraventricular hemorrhage(IVH), ventricular dilatation, CT classification, hematoma diameter, 4th ventricle dilatation, and treatment modality. RESULTS: The results were as follows: 1) Of the 40 patients with GCS of 3 to 8, 15 patients(37.5%) died. Of the 34 patients with GCS of 13-15, 33 patients(97%) survived 2) The 99 patients had intraventricular hemorrhage and 25 patients(25.2%) died. The 28 patients had no intraventricular hemorrhage and they all survived. 3) Of the 24 patients in whom the cerebrocaudate index(CCI) was more than 0.25, 10 patients(41.6%) died and only 2 patients had good prognosis. The 35 patients had no ventricular dilatation and all 35 patients survived 4) Of the 23 patients extending to hypothalamus or midbrain with ventricular hemorrhage, 11 patients(47.8%) died and 12 patients(52.1%) survived. 5) Of the 10 patients in whom hematoma diameter was more than 45mm, 4 patients(40%) died and 6 patients(60%) had a poor prognosis. 6) The 31 patients had hemorrhagic dilatation of the fourth ventricle and 16 patients(51.6%) died. Of the 29 patients with ventricular hemorrhage and no dilatation, 6 patients(20.6%) died. CONCLUSION: Multiple logistic regression analysis showed prognostic factors: GCS score(p<1/20.0001), extending to hypotahalamus or midbrain with ventricular hemorrhage(p<1/20.0001), thalamic hematoma with IVH(p<1/20.0001), dilated 4th ventricle hemorrhage(p<1/20.0012), hematoma diameter(p<1/20.0001), CCI(p<1/20.0001).

The level of terrorist threats using chemical, biological, and radiological agents has been continuously increasing, and it is an undeniable truth that these agents are actually in use today. The fact that most chemical, biological, and radiological agents cause skin-related symptoms, and that the skin symptoms are observed at a relatively early stage of the condition, leads to the conclusion that dermatologists could be the first point of contact for potential victims of these agents. It is highly important that first responders are able to recognize symptoms caused by these agents early and react quickly. Therefore, dermatologists do have a responsibility to take on a role in dealing with chemical, biological, and radiological attacks, and pre-equip themselves with professional knowledge in this field. Among the various types of chemical agents, typical examples of agents causing skin-related symptoms are blistering agents, which lead to bullae and necrosis on the skin. Biological agents are classified from Category A to C according to their respective risk factors. The most dangerous Category A agents include anthrax, smallpox, plague, tularemia, and viral hemorrhagic fever, all of which are known to show characteristic skin-related symptoms. Upon exposure to a certain level of radiation, radiological agents can also lead to erythema on the skin. In this article, we will discuss various characteristics and up-to-date treatment methods of potential chemical, biological, and radiological agents to help dermatologists advance their knowledge in this field.
