1.Enteric Cyst in the Tongue.
Korean Journal of Pathology 1997;31(11):1237-1239
A case of enteric cyst in the anterior two-thirds of the tongue is reported. The patient, a 42 day-old female infant, presented with a protruding tongue mass since birth. Under the impression of ectopic thyroid gland or leiomyoma, complete resection was performed. The mass proved to be an enteric cyst, lined by small intestinal mucosa with an underlying coat of smooth muscle. Enteric cysts arising in the tongue is rare and only 8 such cases have been reported in the literature.

Angiogenesis depends on the net balance between positive and negative angiogenic factors. Tumor cells are angiogenic resulting from increased production of positive factors and decreased production of negative factors. Among these, vascular endothelial growth factor and glioma- derived angiogenesis inhibiting factor are related to glioblastoma multiforme. The p53 gene is more frequently mutated than any other known oncogene or tumor suppressor gene in human tumors including glioblastoma multiforme. Angiogenesis is reported to be controlled by p53 regulation in recent studies. To examine the effect of p53 overexpression on angiogenesis in glioblastoma multiforme, we performed immunohistochemical staining in 51 cases of glioblastoma multiforme, using monoclonal antibodies to p53 protein and factor VIII. 20 cases of low grade astrocytoma were used as control. p53 overexpression was present in 15(75%) of 20 cases of low grade astrocytoma and the mean vessel count was 37.7+/-9.9 at x200 field and 17.5+/-5.8 at x400 field. p53 overexpression was present in 35(68%) of 51 cases of glioblastoma multiforme and the mean vessel count was 91.9 45.8 at x200 field and 40.7 19.1 at x400 field. Mean vessel count in low grade astrocytoma with p53 overexpression was 39.4 10.2 at x200 field and 18.9 5.7 at x400 field, while in cases without p53 overexpression it was 32.4+/-7.6 at x200 field and 13.2 3.5 at x400 field. Mean vessel count in glioblastoma multiforme with p53 overexpression was 94.5+/-51.8 at x200 field and 42.1+/-16.8 at x400 field, while in cases without p53 overexpression it was 86.1+/-29.5 at x200 field and 37.1+/-16.8 at x400 field. The mean survival time was 12.4 months in the 39 cases of glioblastoma multiforme in which follow-up studies were possible. Significant prognostic factors were age, p53 overexpression and adjuvant therapy. These results show that p53 gene mutation is one of the many contributing factors to angiogenesis in glioblastoma multiforme. In addition, other oncogenes and tumor suppressor genes, as well as growth factors may be involved. Age, p53 overexpression and adjuvant therapy proved to be significant prognostic factors, while microvessel density was not.

PURPOSE: The aim of this study was to evaluate the use of dehydrated human amnion/chorion membrane (dHACM) to repair perforated sinus membranes in rabbits. METHODS: Bilateral surgical windows (7.5-mm diameter) were prepared on the nasal bones of 14 rabbits. Standardized circular perforations (5-mm diameter) were made in the sinus membrane by manipulating implant twist drills. The perforated sinus membranes were repaired using dHACM or a resorbable collagen membrane (CM). The negative control (NC) group did not undergo perforated sinus membrane repair, while the positive control (PC) group underwent sinus augmentation without perforations. The same amount of deproteinized porcine bone mineral was grafted in all 4 groups. After 6 weeks, micro-computed tomography (micro-CT) and histomorphometric evaluations were conducted. RESULTS: The micro-CT analysis revealed that the total augmented volume was not significantly different among the groups. In the dHACM group, newly formed bone filled the augmented area with remaining biomaterials; however, non-ciliated flat epithelium and inflammatory cells were observed on the healed sinus membrane. Histometric analysis showed that the percentage of newly formed bone area in the dHACM group did not differ significantly from that in the CM group. The dHACM group showed a significantly higher percentage of newly formed bone area than the NC group, but there was no significant difference between the dHACM and PC groups. CONCLUSIONS: dHACM could be a feasible solution for repairing sinus membrane perforations that occur during sinus floor augmentation.

Inappropriate treatment of the injury of the lateral collateral ligaments of the ankle produce residual instability, which causes serious disability. There is considerable divergence of opinion as to whether fresh rupture of the lateral ligaments of the ankle are best treated by conservative or opreative method. We have conducted a trial to analyze thirty patients, who were treated by immediate open surgical rupair of rupture of the lateral ligaments of the ankle between April 1991 and February 1992. The results were as follows: 1. All patients were active, young men, Injuries to left ankle were three times more than right side. The most common cause of injury is occurred during sports, especially association football. 2. The decision to operate was based on 1)Talar tilt angle of the injured ankle measures 8-10 degrees more than that of the stress uninjured ankle. 2)A positive arthrogram showing contrast leakage into peroneal tendon she-aths & anterolateral aspect of the lateral malleolus. 3. Diagnostic accuracy rate of arthrography is 94.5%, stress radiography 61.1 %. Arthrography is more reliable than stress radiography in the diagnosis of acute injuries to the lateral ligament of the ankle. 4. At operation, isolated rupture of anterior talofibular ligament was in 5 cases, isolated rupture of middle calcaneofibular ligament in 3 cases, concomittant ruptures of anterior talofibular and middle calcaneofibular ligements in 22 cases. 5. Location of tears of anterior talofibular ligament was mostly mid-portion, middle calcaneofibular ligament in mid-portion or distal portion. 6. On radiologic results, average angle of talar tilt was 14.4° preoperatively, 5.2 preoperatively. There was correction of talar tilt angle of average 9.2°. 7. Clinical results of treatment were excellent in 9 patients, good in 6 patients, fair in 4 patients, poor in 2 patients by authors rating system. The satisfactory result was achieved in 15 patients(71.4%). 8. Postoperative complication was reduced mobility in 4 cases, functional instability 1 case, neuroma in operation scar in 2 cases, minor sensory loss in 4 cases. 9. Primary surgical repair gave good results in the aspect of radiologic & fun ctional instability, but clinical results were not satisfactory, due to high incidence of postoperative complication.

The antihypertensive effects fo aldactazide and serum electrolytes changes before and after treatment with aldactazide were observed. The followings were obtained: 1. Results of antihypertensive therapy with aldactazide in 23 hypertensive patients revealed good effects in 52.17%, fair in 26.09%, poor in 8.7%, and failure in 13.04% of cases. In 78.26% of cases, good or fair control of blood pressure was obtained. 2. Daily doses of aldactazide ranged from 25mg to 50mg depending upon the level of blood pressure. The antihypertensive effects were appeared after average 11 days of administration. 3. The side effects during treatment with aldactazide were dizziness, weakness, indigestion, headache, and restlessness in 26.28% of cases (6 of 23 cases). 4. No significant changes in serum Na and K values were observed before and after treatment with aldactazide for average 23 days.

BACKGROUND: Both atrophic gastritis and intestinal metaplasia may progress to gastric dysplasia. This study aimed to analyze the factors influencing progression of atrophic gastritis and intestinal metaplasia to dysplasia. METHODS: People diagnosed with atrophic gastritis and intestinal metaplasia for the first time received a follow-up endoscopy and were investigated for the cumulative incidence rate of gastric dysplasia by age, gender, smoking habit, alcohol intake, rice consumption and family history of stomach cancer. RESULTS: The cumulative incidence rate increased with age, consuming > or =3 bowls of rice per day and family history of stomach cancer. Multivariate analysis showed that the cumulative incidence rate of gastric dysplasia increased in subjects >61 years (RR=2.54, P=0.014), in those consuming > or =3 bowls of rice per day (RR=1.46, P=0.021) and in those with a family history of stomach cancer (RR=1.31, P=0.037). CONCLUSIONS: More active management, such as intensive endoscopic follow-up examinations, lifestyle change and education regarding gastric dysplasia, are required in those older than 61 years, having a higher intake of grain or with a family history of stomach cancer.

For the reconstruction of skin defects after remoral of cutanous tumors in the nasal area, local flaps or full-thickness skin grafts can be utilized depending on the size and site of the defectg. Burows graft, which is, variant of the full-thickness skin graft, makes use of the skin nearby as the donor site, minimizes deformity of the recipient site, maximizes ireservation of skin, easily aligns relaxed skin tension line, and is thus one of the methods with a good esultant color and texture match. A pigmented basal cell carcinoma on the nasal bridge in a 51-year old male was remaved by 4 serial sections of Mohs micrograplic surgery and was then successfully enstructed using a Burows graft.

PURPOSE: To examine the effects of atropine therapy on myopic progression in myopic children. METHODS: Fifty myopic patients, aged from 7 to 14 years and less than -5 diopters, visited our clinic for correction of refractive error from August 2001, and were followed up for at least 1 year. Of these 50 patients, the atropine therapy group was 23 and the control group was 27. Right eye cycloplegic refraction and axial length changes of the two groups were compared and analyzed. RESULTS: There was a mean increase of myopia of 0.25+/-0.43 D/yr in the atropine therapy group and of 0.83+/-0.37 D/yr in the control group (P=0.000). There was a mean increase of axial length of 0.12+/-0.19 mm/yr in the atropine therapy group and 0.39+/-0.21 mm/yr in the control group (P=0.000). In refraction and axial length changes according to age, there was no statistically significant difference within the group, aged from 7 to 9 years. However, there was a statistically significant difference within the group, aged from 10 to 14 years. In refraction and axial length changes according to myopic grade, there were a statistically significant differences between the groups. CONCLUSIONS: Atropine therapy is effective in slowing the myopic progression in myopic children with refractive error less than -5 diopters.
