Basal cell carcinoma is the most common skin cancer, especially on the eyelid and nose. As it rarely invades to a underlying bone or metastasizes an distant site, and is usually found at an early stage, it is regarded as a curative disease. However, basal cell carcinoma on the eyelid and nose may be resected incompletely due to efforts to preserve important structures or as a result of esthetic considerations. We experienced two cases of basal cell carcinoma with local invasion to underlying bone. One was a recurred case on the nasal area extending to the nasal bone arts medial wall of the ethmoid sinus. The lesion was widely resected and covered with a radial forearm free flap. The other was on the eyelid extending to the orbit. It was treated with orbital exenteration and resection of the involved eyelid. The defect was reconstructed with the temporalis muscle flap with split-thickness skin graft. These patients were followed up for 7 months with no evidence of recurrence. Since basal cell carcinoma can invade to the bone and metastasize to a distance site, it should be resected radically in the regions of the eyelid and nose.

3.Isometric bite force and its relation to craniofacial morphology.
Korean Journal of Orthodontics 1991;21(1):185-195
This study was undertaken to grope the correlation of the maximal bite force and toothcraniofacial structure. The maximal bite force of 76 adult male, aged 18-28 (mean aged: 23.4 +/- 2.2) years, was estimated and cephalometric headplates were measured, tabulated and statistically analyzed. The results were as follows. 1. 59.61kg of bite force in first molar, 45.38kg in premolar and 17.10kg in central incisor were arranged. 2. The bite force was negatively correlated to gonial angle, mandibular plane angle, the angle between occlusal plane and mandibular plane, the angle between palatal plane and mandibular plane, and positively correlated to posterior height of face, length of mandibular body, length of ramus, facial depth in craniofacial structure. 3. The group with strong bite force showed small genial angle, rnandibular plane angle, the angle between occlusal plane and mandibular plane, the angle between palatal plane and mandibular plane, and long posterior height of face, length of mandibular body, length of ramus, facial depth. So they manifested the tendency to brachycephalic pattern, on the other hand, the group with weak bite force manifested the tendency to dolichocephalic pattern. 4. There is no correlationships between bite force and mesial inclination of premolar axis in this subject. 5. It is considered bite force have an effect upon craniofacial pattern, especially upon the lower face.

OBJECTIVE: To evaluate the effects of gabapentin and clonidine on neuropathic pain in an experimental pain model. METHOD: 24 male adult rats were anesthetized and the sciatic nerve was exposed. Each exposed nerve was electrically injured with 10 volts for 10 seconds by two needle electrodes. Rats were divided into three groups by treating with gabapentin, clonidine and sham. Gabapentin and clonidine were given orally from post operation day 3 to 7 in gabapentin and clonidine groups respectively. To evaluate the presence of mechanical allodynia, withdrawal frequency was tested by Von Frey hair in the same days. After post operation day 7, all the medications were discontinued and mechanical allodynia was evaluated at post operation day 14. RESULT: Neuropathic pain was developed after electrical injury in all the rats. Withdrawal frequency is more decreased in gabapentin and clonidine groups than sham group in post operation day 4 to 7. The withdrawal frequency was 2.88+/-0.83, 2.75+/-0.89, 3.13+/-0.99, 3.25+/- 1.28 in gabapentin group and 3.38+/-0.92, 4.50+/-2.20, 3.25+/-1.17, 3.50+/-0.93 in clonidine group in post operation day 4, 5, 6, 7, respectively. In post operation day 14, withdrawal frequency was increased and showed no difference compared to the sham group. CONCLUSION: Gabapentin and clonidine can suppress the neuropathic pain in an experimental pain model. There was no different effect on the neuropathic pain suppression between gabapentin and clonidine.

Dermatofibrosarcoma protuberans (DFSP) is a rare, distinctive cutaneous tumor, which consists of spindle shaped ceils arranged in densely packed interlacing bundles with the storiform or cartwheel pattern. Histologically, it resembles deep growing dermatofibroma, nodular fasciitis, neurofibroma and neural sheath tumors. DFSP is one of t.he connective tissue tumors which is difficult. to diagnose histologically as well as clinically. Recently, the immunochemical staining with a monoclonal antibody to CD34 is reported to give assistance in the clear differential diagnosis of DFSP from other fibrous or neural tumors. Herein, three cases of DFSP were stained by immunohistochemical staining with S-100 protein, vimentin, factor VIII and anti-CD34 antibody in order to assess the use of anti-CD34 in the differential diagnosis of DFSP.

7.Immune Response and the Tumor Microenvironment: How They Communicate to Regulate Gastric Cancer.

Gastric cancer is the second most common cause of cancer-related death in the world. A growing body of evidence indicates that inflammation is closely associated with the initiation, progression, and metastasis of many tumors, including those of gastric cancer. In addition, approximately 60% of the world's population is colonized by Helicobacter pylori, which accounts for more than 50% of gastric cancers. While the role of inflammation in intestinal and colonic cancers is relatively well defined, its role in stomach neoplasia is still unclear because of the limited access of pathogens to the acidic environment and the technical difficulties isolating and characterizing immune cells in the stomach, especially in animal models. In this review, we will provide recent updates addressing how inflammation is involved in gastric malignancies, and what immune characteristics regulate the pathogenesis of stomach cancer. Also, we will discuss potential therapeutics that target the immune system for the efficient treatment of gastric cancer.

1. 110 cases of optic atrophy from 7 months to 67 years old, 82 bilateral with 28 unilateral involvement observed at the National Medical Center in Korea Between 1959 and 1961 were analyzed for etiologic factors which were which were also based on a a review of literature. 2. Of the 110 cases, the largest single cause of optic atrophy af all type was brain tumor(18 cases, 16.4%) with exogenous poisoning(11 cases, 10%) second in frequency. 3. Cases of atrophy due to tuberculous meningitis(10 cases, 9.1%) were found in the age group of one to 15 years as the most frequent cause in childhood. 4. The retrobulbar neuritis was one of the most frequent causes(9 cases, 8.2%) in the adult. Also the traumatism(8 cases, 7.3%) as to the prevalent acuses of post-war blindness. 5. A characteristically low incidence of syphilis (4 cases, 3.6% without congenital syphilis) as the cause of the optic atrophy is one of the subject to be evaluated in the future.

Spontaneous regression of an intracranial lesion, as seen in sequential CT or MRI images, does not necessarily indicate a self-limiting process such as trauma or vascular disease. This report describes two cases of intracranial enhancing lesions which, on follow-up, showed complete resolution of the changes seen on MRI, without any treatment other than the administration of corticosteroid for a short period. We review several reports of "disappearing CT lesions", and discuss the possible mechanism of disappearance of intracranial lesions.
