Benign odontogenic neoplasms are rare, but malignant odontogenic neoplasms are extremely rare. The majority of malignant epithelial neoplasms occurring in the jaws are the result of metastasis from distant primary neoplasms of direct invasion from contiguous carcinoma of the oral mucosa, sinus mucosa, salivary gland or skin. A few remaining primary intraosseous carcinoma of the jaw are presumed to be of mostly odontogenic origin since epithelial remnants of odontogenesis are numerous in the maxilla arts mandible. Although calcifying odontogenic cyst(COC) is a well-established pathologic entity, it has been recognized that there is an odontogenic neoplasm with histologic features similar to the COC(malignant epithelial odontogenic host cell tumor; EOGCT) that has been diagnosed as COC. Some authors have reported previously in the literature describing malignant EOGCT. We experienced one case of malignant EOGCT with aggressive growth pattern and histologic features strongly implying its malignant potential. The lesion was excised by anterior mandibular resection, total 1 resection of the tongue and bilateral functional neck dissection. The tongue was reconstructed by using the infrahyoid muscle neurovascular island flap and neurovascular radial forearm free flap. The mandible was reconstructed by using the osteocutaneous fibular free flap.

PURPOSE: To determine the metabolic characteristics of recurrent stone formers (RSF), we investigated urinary lithogenic factors. MATERIALS AND METHODS: The 24-hour urine samples of 151 RSF (114 men, 37 women) and 70 normal controls (33 men, 37 women) were analyzed for excretion rate differences of lithogenic and inhibitory constituents such as volume, sodium, phosphorus, uric acid, calcium, magnesium, oxalate, and citrate. The incidence and spectrum of metabolic abnomality in REF were aldo determined. RESULTS: The RSF showed significantly increased excretion of phosphorus (p=0.004), uric acid (p=0.003), and calcium (p=0.007) and decreased in that of citrate (p=0.044). No significant differences were found between the RSF and normal controls with regard to the excretions of sodium, magnesium, oxalate, and volume. The most frequent metabolic abnormality in RSF was hypocitraturia (43.7%), followed by hypernatriuria (41.7%), hypercalciuria (23.2%), and hyperuricosuria (20.5%). At least one metabolic abnormality was found in 118 of out of 151 RSF (78.1%). CONCLUSIONS: Our results showed that RSF had different urinary excretions of citrate as well as phophorus, uric acid, and calcium compared to the normal subjects and metabolic abnomalities were found up to 80% of them. The 24-hour urine study would be an effective means for metabolic evaluation in RSF although diagnostic accuracy increases with repeated examination.

BACKGROUND: From 1980s the methamphetamine(phillopon) was suddenly spread to our country and it becomes a serious social problem. Although the proportion of transfusion associated hepatitis C declined after introduction of Anti-HCV assay as screening test of blood donors, the overall prevalence of hepatitis C has remained the same, primarily because of increase of the proportion of hepatitis C patients among intravenous drug abusers. So we studied about prevalence of Anti-HCV, and other viral infectious disease transmission by intravenous drug abuse. METHODS: Total 202 drug abusers who had been admitted to Taegu Medical Center in 1994-1996 were tested for the presence of Anti-HCV. Epidemiologic data and histories related to drug use were obtained, as were serum test for hepatitis B, aminotransferase, HIV. RESULTS: The overall seropositivity of anti-HCV was 79.2%. Patients In HCV positive group were significant old age(34.0 yrs) and had long duration of injection(3.0 yrs) and the number of patient who had elevated aminotransferase level were significantly more than HCV negative group(p<0.05). No significant difference in sex, prevalence of HBs Ag and Anti HBc were observated between HCV positive group and negative group. The prevalence of Anti HBc was 52.1% and HBs Ag was 4.2%, but anyone was not detected for AIDS. CONCLUSIONS: The seropositivity of Anti-HCV in intravenous drug users in Taegu, Korea was 79.2%, comparable to that in Europe and U.S.A. This finding suggest that its time to hurry up for medical and public walfare service personal to concern and education of drug abusers, and inview of preventive medical care the need of general public information and education is pressing.

PURPOSE: To evaluate dysphagia objectively and quantitatively, and ta clarify the effect of neck position and viscosity changes in patients with aspiration and laryngeal penetration. MATERIALS AND METHODS: We studied 35 patients with dysphagia and 21 normal controls using videofluoroscopy and scintigraphy. Videofluoroscopy was performed with barium with three different viscosity, and scintigraphy was done, with water, yogurt, and steamed egg mixed with Tc-99m tin colloid. 1f aspiration was found during videofluoroscopic examination, patients neck position was changed and study repeated. Videofluoroscopy was analyzed qualitatively. We calculated 7 quantitative parameters from scintigraphy. According to the videofluoroscopic findings, we divided patients into 3 subgroups; aspiration, laryngeal penetration, and no-aspiration group. RESULTS: The result of videofluoroscopy revealed that the most cornmon finding was the delay in triggering pharyngeal swallow. Pharyrigeal transit time (PTT) and pharyngeal swallowing efficiency(PSE) in patients with aspiration were significantly different from other groups. After neck position change, aspiration could be reduced in all of 7 patients, and laryngeal penetration reduced hy about 82%. PTT ancl PSE were also improved after position change. Aspiration and laryngeal penetration occurred more frequently in thin liquid swallowing than in thick liquid and solid swallowing. CONCLUSION: PTT and PSE were useful for the evaluation of dysphagia. Aspiration and laryngeal penetration could be reduced when appropriate position assumed, We could decrease the chance of aspiration by changing the patient diet consisIency. Scintigraphy might be useful tool to quantitate and follow up these changes.

Intra-uterine fracture of normal bone is extremely rare. It was reported few cases in the other contries, but it was very rare in Korea. It is difficult to distinguish it from birth fracture and the other fractures or deformities seen at birth. The authors experienced a case of intra-uterine fracture of the femur in the middle third of the shaft, with abundant callus formation in infant without serious injury to the mother.
