Metronidazole is a nitroimidazole antibiotic used for anaerobic infections, protozoan infections, and Helicobacter pylori infections. It may produce rare but well known neurological adverse effects including peripheral neuropathy, encephalopathy, cerebellar dysfunction, and seizures. We describe three patients with metronidazole-induced reversible cerebellar dysfunctions characterized by abnormal oculomotor findings, dysmetria, and ataxia. The diagnosis of metronidazole toxicity was made clinically and supported by the brain MRI findings. The neurological signs and abnormal signal intensity on MRI resolved after discontinuation of metronidazole.

When we deal with maxillary and mandibular anterior dental arches showing problems in occlusal relation and aesthetics caused by malformations of teeth and congenital missing, et al during the orthodontic treatment, we could not often decide the functional occlusion by only relying on the orthodontic treatment. If orthodontists can predict what kinds of treatments are needed for functional occlusion in maxillary and mandibular anterior dental arches, they can not only effectively treat patients but also facilitate the cooperation with other field during the treatment. Our previous research showed the correlation among intercanine width, segment depth and arch perimeter by using the Korean normal occlusion model. At this time, we produced the computer application program by taking advantage of this correlation. And then, we applied this program to setting up the treatment plans for 2 patients with the damaged maxillary and mandibular dentures. With the help of this program, we could not only easily acquire the information about the change of variables required by treatment plans but also understand the change of the anterior dental occlusion corresponding to the change of each variables such as the intercanine width, segment depth and arch perimeter. Later, if we can have the information about the relationship between the change of the angle of incisors depending on facial types and arch forms and, in addition, can acquire the appropriate intercanine width, we can have the ability to produce the 3 dimensional occlusogram for the anterior dental arch forms.

When performing septoplasty in patients with a high deviation of the nasal septum, effective correction is difficult and postoperative complications such as a saddle nose may result if the bone or cartilage is removed inordinately. Although several surgical techniques have been introduced, some are difficult to apply easily. Furthermore, the deviation may persist despite the application of surgical techniques due to the rebound memory of the remaining cartilage. This study aimed to describe a simple and safe surgical technique for crooked nasal septa with a high deviation. This method using horizontal dorsal septal incision allows easy separation of the highly deviated portion from the upper lateral cartilage. Furthermore, it is less traumatic than other methods, and predictably preserves the keystone area.

The 43 cases of the primary uterine cervical carcinoma were analyzed for HPV type 16/18 infection and also analyzed for overexpression of p53 and c-erb B2 oncoprotein to evaluate theirs oncogenic and clinicopathologic relationships. HPV type 16/18 infection was examined by polymerase chain reaction(PCR) and the overexpression of p53 and c-erb B2 protein by using immunohistochemical method. The results were as follow: 1. The HPV infection rate in primary uterine cervical carcinomas was 83.7% respectively.The standard clinicopathologic characteristics(age, histologic type, koilocytosis, mitosis, clinical stage, tumor size, cervical invasion depth, lymph node metastasis, parametrial invasion) were nat significantly correlated with HPV type 16/18 infectivity. 2. The overexpression rate of p53 protein was 72.1% and there was no Significant correlation between expression of p53 protein and the Clinicopathologic characteristics. 3. The overexpression of c-erb B2 oncoprotein was 44.2% and there was no significant correlation between the overexpression of c-erb B2 oncoprotein and the clinicopathologic characteristics. 4. There was no significant correlation between HPV type 16/18 infection and overexpression of p53 and c-erb B2 oncoprotein.

It is very rare for the primary lung cancer to metastasize to gastrointestinal tract, which has poor prognosis. A 72-year-old man admitted with dyspnea and a mass lesion in the left lower lobe on chest roentgenogram and chest computed tomogram(CT). Large cell carcinoma of the lung was diagnosed by percutaneous needle biopsy. Also gastroduodenoscopy was conducted for evaluation of gastrointestinal symptoms, such as indigestion and epigastric discomfort. Large cell carcinoma of duodenum was diagnosed by biopsy of duodenal polyp, which was considered to be metastasized from the primary lung cancer. Palliative radiation therapy was performed, but he died 2 months after diagnosis. We report a rare case of large cell carcinoma of the lung with metastasis to uodenum.

OBJECTIVES: This study was conducted to evaluate association between computerized neurobehavioral performance and blood lead concentration in Korean elementary school students. METHODS: The subjects were 1,077 elementary school students of Seoul, Busan, Daegu and Gwangju. Blood lead concentration was measured and computerized neurobehavioral performance tests were performed. RESULTS: Blood lead concentration of the subjects was in the range of 0.20 and 7.39 microg/dl. The geometric mean of the subjects' blood lead concentration was 1.41 microg/dl. As blood lead concentration increased, reaction time to the symbol digit tended to increase significantly and linearly. As a result of LOWESS(locally weighted scatterplot smoothing), increasing reaction time to the symbol digit was observed. CONCLUSIONS: As blood lead concentration under the CDC (center for disease control and prevention) reference value increased, reaction time to the symbol digit tended to increase. But, as the number of subjects over 3 microg/dl is small, it is difficult to make a definite conclusion. If confounding variables are controlled properly in a follow-up study, we can obtain a more definite conclusion.

BACKGROUND: An association between serum calcium level and risk of metabolic syndrome (MetS) has been suggested in cross-sectional studies. This study aimed to evaluate the association between baseline serum calcium level and risk of incident MetS in a longitudinal study. METHODS: We conducted a retrospective longitudinal study of 12,706 participants without MetS who participated in a health screening program, had normal range serum calcium level at baseline (mean age, 51 years), and were followed up for 4.3 years (18,925 person-years). The risk of developing MetS was analyzed according to the baseline serum calcium levels. RESULTS: A total of 3,448 incident cases (27.1%) of MetS developed during the follow-up period. The hazard ratio (HR) for incident MetS did not increase with increasing tertile of serum calcium level in an age- and sex-matched model (P for trend=0.915). The HRs (95% confidence interval [CI]) for incident MetS comparing the second and the third tertiles to the first tertile of baseline serum calcium level were 0.91 (95% CI, 0.84 to 0.99) and 0.85 (95% CI, 0.78 to 0.92) in a fully adjusted model, respectively (P for trend=0.001). A decreased risk of incident MetS in higher tertiles of serum calcium level was observed in subjects with central obesity and/or a metabolically unhealthy state at baseline. CONCLUSION: There was no positive correlation between baseline serum calcium levels and incident risk of MetS in this longitudinal study. There was an association between higher serum calcium levels and decreased incident MetS in individuals with central obesity or two components of MetS at baseline.

The diffuse form of supravalvar aortic stenosis represents a surgical challenge when the ascending aorta, aortic arch, proximal descending thoracic aorta and arch arteries are involved. It can be treated by a variety of surgical approaches. We report a case of severe diffuse supravalvar aortic stenosis combined with an aortic valve anomaly and occlusion of the right coronary artery ostium in a 14-year-old boy with Williams syndrome. We enlarged the aortic root (Nick's procedure), ascending aorta, aortic arch, proximal descending thoracic aorta, and innominate artery with patches and replaced aortic valve with 19 mm St. Jude valve. Deep hypothermic circulatory arrest and retrograde cerebral perfusion were used during repair of the arch and arch artery.
