The Kallmanns syndrome is the most common form of isolated hypogonadotropic hypogonadism in which anosmia or hyposmia resulting from agenesis of hypoplasia of the olfactory lobes is associated with LHRH deficiency, This syndrome is genetically heterogeneous and can be trans-mitted as an X-linked, autosomal dominant or autosomal recessive trait. The hypogonadotropic hypogonadism results in absent or incomplete pubertal development and may be associated with anosmia or hyposmia, mid-line defect(color blindness, cleft-lip or

Purpose: We performed three-dimensional (3D) dose reconstruction-based pretreatment verification to evaluate gamma analysis acceptance criteria in volumetric modulated arc therapy (VMAT) for prostate cancer. Materials and Methods: Pretreatment verification for 28 VMAT plans for prostate cancer was performed using the COMPASS system with a dolphin detector. The 3D reconstructed dose distribution of the treatment planning system calculation (TC) was compared with that of COMPASS independent calculation (CC) and COMPASS reconstruction from the dolphin detector measurement (CR). Gamma results (gamma failure rate and average gamma value [GFR and γAvg]) and dose-volume histogram (DVH) deviations, 98%, 2% and mean dose-volume difference (DD98%, DD2% and DDmean), were evaluated. Gamma analyses were performed with two acceptance criteria, 2%/2 mm and 3%/3 mm. Results: The GFR in 2%/2 mm criteria were less than 8%, and those in 3%/3 mm criteria were less than 1% for all structures in comparisons between TC, CC, and CR. In the comparison between TC and CR, GFR and γAvg in 2%/2 mm criteria were significantly higher than those in 3%/3 mm criteria. The DVH deviations were within 2%, except for DDmean (%) for rectum and bladder. Conclusions The 3%/3 mm criteria were not strict enough to identify any discrepancies between planned and measured doses, and DVH deviations were less than 2% in most parameters. Therefore, gamma criteria of 2%/2 mm and DVH related parameters could be a useful tool for pretreatment verification for VMAT in prostate cancer.

We report a 77-year-old woman with bilateral pons infarction who presented with severe trismus, which was responsive to botulinum toxin-A injection. She was unable to open her mouth and showed anterior displacement of her temporo-mandibular (TM) joint on MRI findings. She was fed via nasogastric tube because of mouth opening limitation. There was no improvement of her mouth opening after range of motion exercise. She underwent closed reduction of the TM joints under general anesthesia but there was no significant improvement. Electromyography studies revealed continuous muscle activities on masseter and temporalis muscles during mouth opening. Botulinum toxin-A (Botox(R)) was injected into both the masseter and left temporalis muscles under ultrasonographic guidance. There was some improvement in mouth opening at post-injection 5 days. The inter-incisal distance improved gradually, and she could start oral feeding after 18 days. She could maintain an inter-incisal distance of 1.8 cm with favorable response during post-injection 4 months.

Even a single brain infarct can cause dementia when it occurs in functionally critical areas of the brain. A 71- year-old female developed sudden cognitive impairment without any other focal neurologic deficits. A brain MRI revealed a bilateral anterior fornix infarction. Neuropsychological evaluation revealed verbal and visual memory deficits, visuospatial dysfunction, and frontal executive dysfunction. The cognitive impairment did not improve for 3 months and the patient showed impairments in daily activities. We report a patient who demonstrated strategic infarct dementia after a bilateral anterior fornix infarction.

OBJECTIVE: To assess the clinical usefulness of ultrasonography for the diagnosis of mild and very mild carpal tunnel syndrome. METHOD: Ultrasonographic evaluation was performed in 39 hands of 29 patients with mild and very mild carpal tunnel syndrome according to Bland's neurophysiologic grading scale. Controls included 41 hands of 34 subjects without electrophysiologic evidence of carpal tunnel syndrome. Ultrasonographic findings were evaluated quantitatively with regard to the cross-sectional area, the flattening ratio, the swelling ratio of the median nerve, and palmar displacement of the flexor retinaculum. The analysis of differences between controls and patients group were done by independent t-test. Cut-off values using receiver operation characteristic, were calculated. RESULTS: Patients had significantly increased cross sectional area and flattening ratio of the median nerve at proximal carpal area, palmar displacement of the flexor retinaculum at proximal carpal area. A critical value of equal or higher to 8.5 mm(2) for cross-sectional area at the pisiform level showed a sensitivity 79.5%, a specificity of 95.1%, which had most diagnostic value compared with the value of cross-sectional area at the distal radius level, flattening ratio at the pisiform level and palmar displacement. CONCLUSION: Ultrasonography was useful in the diagnosis of mild and very mild carpal tunnel syndrome.

Infection with Helicobacter pylori (H. pylori) is strongly associated with duodenal and gastric ulcers. Substantial epidemiological data has revealed that high rates of H. pylori infection might be related to high rates of gastric cancer and gastric adenocarcinoma. In this study, a medicinal herbal plant, Cinnamomum cassia, was examined and screened for anti-H. pylori activity. Seventy percent ethanol was used for herbal extraction. For anti-H. pylori activity screening, inhibitory zone tests as an in vitro assay and in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. Also, the safety of herbal compounds was evaluated by animal study. As a result of inhibitory zone test, Cinnamomum cassia extract demonstrated strong anti-H. pylori activities. Also, as results of in vivo animal studies, Cinnamomum cassia demonstrated strong therapeutic effects against H. pylori infection according to the criteria of histological examination and rapid urease test. As results of the safety study, after 28 days treatment of the Cinnamomum cassia extract, the animals were not detected any grossly and histological changes. These results demonstrate that it can be successfully cured against H. pylori infection and protected from H. pylori-induced pathology with Cinnamomum cassia. It could be a promising native herb treatment for patients with gastric complaints including gastric ulcer caused by H. pylori.

Central pontine myelinolysis (CPM) is well-recognized osmotic demyelination syndrome that is related to various conditions such as rapid correction of hyponatremia and chronic alcoholism. Acute ataxia as a sole clinical sign in CPM is rare. We report a case of a 59-year-old man with dysarthria, intention tremor, and a significant gait ataxia starting after alcohol withdrawal, with radiological evidence of CPM. CPM should be included in the differential diagnosis of alcoholic patients who develop a sudden ataxia. Chronic alcohol abuse is one of the most commonly encountered predisposing factors. Alcohol withdrawal represents an additional vulnerability factor, being responsible for electrolyte imbalances which are not always demonstrable but are certainly involved in the development of CPM.

Hemichorea have been reported in patients with nonketotic hyperglycemia. Usually, hemichorea and hyperglycemia are concomitant. A 73-year-old woman was admitted for investigation of an acute hemichorea. T1-weighted brain magnetic resonance imaging showed hyperintensity in the right putamen. Although she was a diabetic patient, she had no hyperglycemia. Interestingly, 4 weeks earlier, the patient was admitted due to nonketotic hyperglycemia. However, there were no hemichorea at that time. Although pathophysiologically controversial, a delayed hemichorea without nonketotic hyperglycemia should be considered as one of many different causes when evaluating acute hemichorea in diabetic patients.

PURPOSE: The purpose of this study was to evaluate the CT features of second branchial cleft cysts. MATERIALS AND METHODS: We retrospectively analyzed the computed tomographic images in nine cases of second branchial cleft cyst which was confirmed pathologically. Emphasis was on localization of the masses to fascial spaces as defined by the deep cervical fasica. RESULTS: In all nine cases, the lerions were located in the submandibular and carotid spaces. Among these cases, six(67%) had simultaneous involvement of the other contiguous spaces, such as anterior and posterior cervical spaces. All cases had round or oval, unilocular, cystic masses with partial or complete rim enhancement. In eight cases(89%), smooth and thin walls were observed. In one case, thick wall and septations were noted. No definite calcifications were noted in all cases. The internal contents of cystic masses showed relatively homogeneous appearance, and CT number ranged from 20 to 35.2 Hounsfield unit(HU)(mean, 28.4HU). CONCLUSION: CT diagnosis of second branchial cleft cyst would be easily obtained from recognition of frequent simultaneous involvement of the other contiguous spaces, along with a typical location and characteristic morphology.
