Hemichorea-hemiballism is a rare complication of nonketotic hyperglycemia in type 2 diabetes mellitus (T2DM). It can be complicated in long-standing type 1 diabetes mellitus or T2DM, and has been described as a presenting symptom of new-onset diabetes. Rapid correction of diabetic ketoacidosis may also cause the delayed hemichorea. Although hyperglycemic hemiballism rarely causes generalized chorea due to bilateral basal ganglia involvement, patients typically present with hemichorea developing over days to months in the setting of elevated serum glucose. On T1-weighted brain magnetic resonance imaging and computed tomography scan a high signal intensity lesion at the basal ganglia is characteristic. After the correction of hyperglycemia, the movements generally disappear within hours, but atypical cases with delayed onset after the resolution of hyperglycemia, unremitting severe movements, and late recurrence are also reported. We report two cases of female T2DM patients who presented with hemichorea. One patient presented with hemichorea in nonketotic hyperglycemia, and the other with delayed onset hemichorea after the resolution of hyperglycemia.

PURPOSE: To develop a novel, simplified method for correcting the ischemic index of nonperfused areas in diabetic retinopathy (DR). METHODS: We performed a retrospective review of 103 eyes with naive DR that underwent ultra-widefield angiography (UWFA) over a year. UWFAs were graded according to the quantity of retinal non-perfusion, and uncorrected ischemic index (UII) and corrected ischemic index (CII) were calculated using a simplified, novel method. RESULTS: The average differences between UII and CII in the non-proliferative DR group and the proliferative DR group were 0.7 +/- 0.9% in the <25% CII group, 3.0 +/- 0.9% in the 25% to 49.9% CII group, and 3.6 +/- 0.6% in the >50% CII group, respectively. A CII >25% was critical for determining DR progression (p < 0.001). CONCLUSIONS: Distortion created by UWFA needs to be corrected because the difference between UII and CII in DR increases with the ischemic index.

OBJECTIVE: This study was designed to investigate the efficacy in the combination of haloperidol and clonidine with chronic schizophrenia. Moreover, we evaluated the effects of clonidine to the plasma haolperidol and reduced haloperidol concentration 36 patiens were entered on 4 weeks by the double blind trial. METHOD: The patients (male=11, female=25) were randomly divided into two groups of eighteen patients each. Their antipsychotic medication was fixed for 2 weeks before double blind trial with haloperidol and clonidine or placebo. Clonidine was started at 0.15 mg/day and then raised 0.6mg/day during 4 days, and the placebo was applied by same method as clonidine. The clinical assessment of the patients was assessed with BPRS and NOSIE. The plasma concentrations of haloperidol and reduced haloperidol were measured by HPLC (UV detector). RESULTS: 1) There were no statistical differences in sex distribution, age, duration of illness, dosages of haloperidol, plasma concentration of haloperidol and reduced haloperidol of each groups before clonidine or placebo trial. 2) On total and subcluster scores of BPRS and total score of NOSIE, there were decreased tendencies over the time, but there was no statistical significance in both groups. 3) Plasma concentrations of haloperidol and reduced haloperidol after 4 weeks of clonidine trial were revealed statistically significant increasement as compared to baseline. CONCLUSION: The combination of haloperidol and clonidine for 4 weeks did not reveal the improvement. In our opinions the reasons of those results were that our samples were not made of paranoid type of schizophrenia, the duration of clonidine trial was not good enough. So we should suggest that more specifying design will be needed.

PURPOSE: Little data is currently available on the use of the impulse oscillometry system (IOS) parameter in analyzing the lung function of young children with cough-variant asthma (CVA) and classic asthma. The aims of this study were to evaluate the bronchial responsiveness between patients with CVA and those with classic asthma using dose-response slope and various cutoff values. METHODS: A methacholine challenge test and a pulmonary function test were performed in 43 children with classic asthma and 26 children with CVA using IOS, and the respiratory resistance (Rrs) and reactance (Xrs) were obtained. The bronchial responsiveness were assessed by provocative concentration causing an 80% fall from baseline in reactance at 5 Hz (PC80_Xrs5) and a 40% increase in resistance at 5 Hz (PC40_Rrs5) and calculating from the degree of dose-response slope (DRS) for airway resistance and reactance. RESULTS: There was no significant difference in base lung function between the two groups. However, the mean DRS_Xrs5 and the number who showed more than an 80% fall in reactance were significantly higher in classic asthma group than those in CVA group (P=0.040 and P=0.040, respectively). CONCLUSION: The use of DRS in oscillatory reactance at 5 Hz is useful for the differential diagnosis of classic asthma and CVA based on bronchial hyperresponsiveness.

Wegener's granulomatosis is a small vessel vasculitis characterized by necrotizing granulomatous inflammation of the upper and lower respiratory tracts and kidney. Early diagnosis and immediate treatment are very important for a better prognosis, but the nonspecific, variable clinical manifestations and radiologic findings make the diagnosis difficult. A positive proteinase 3-antineutrophil cytoplasmic antibody test is helpful for the diagnosis of Wegener's granulomatosis. Here, we report a case of Wegener's granulomatosis in 54-year-old man who initially presented with fever and multiple cavitary consolidations on the chest radiograph suggestive of a lung abscess. The final diagnosis of Wegener's granulomatosis was based on the medical history of otitis media, gradually developed microscopic hematuria, necrotizing granulomatous inflammation on lung histopathology, and a positive proteinase 3-antineutrophil cytoplasmic antibody test.

OBJECTIVES: Neurotensin (NT), of which functions are evoked by its interaction with neurotensin receptors (NTR), coexists with mesolimbic dopamine and regulates endogenous dopamine release. Recent studies have shown that NT with NTR exerts neuroleptic-like activity within the central nervous system and may play an important role in the pathogenesis and in the treatment of schizophrenia. We have examined the genetic association between schizophrenia and tetranucleotide repeat polymorphism in the 3'-flanking region of the NTR gene to investigate the possible contribution of the NTR gene to the schizophrenia susceptibility. METHODS: Among 23 alleles identified, the subjects were 120 patients (male 91, female 29) with schizophrenia and 106 normal healthy controls (male 84, female 22). They were unrelated native Korean. PANSS was used to determine positive or negative subgroup in the schizophrenic patients.Using polymerase chain reaction and polyacrylamide gel electrophoresis, tetranucleotide repeat polymorphism (CCTT and CTTT) in the 3'-flanking region of NTR gene was observed. For a comparison of NTR gene's allelic frequencies between patients with schizophrenia and normal healthy controls, chi-square test and Bonferroni's correction was performed. RESULTS: The frequency of A10 allele (base pair size=399) was significantly higher in normal healthy controls than schizophrenia (x2=16.4902, df=1, p<.000). In the comparison between schizophrenic patients with negative symptoms and normal controls, the frequency of A10 allele was significantly higher in normal healthy control subjects than patients with schizophrenia (x2=21.33, df=1, p<0.001). In the case of male, the frequency of A10 allele of schizophrenia was significantly higher than normal controls (x2=13.71, df=1, p<0.001). CONCLUSIONS: NTR gene was negatively associated with schizophrenia. NTR gene's tetranucleotide repeat polymorphism may provide some protective function against schizophrenia.

Pentatrichomonas hominis is considered a commensal protozoan in the large intestine of a number of mammalian hosts, such as cats, dogs, and non-human primates. The resulting infections, which can induce diarrhea, have been attributed to opportunistic overgrowth of P. hominis. This study was performed to confirm the P. hominis infection and its molecular characterization from the feces of puppies with diarrhea. Fecal samples were obtained from 14 German shepherd puppies with diarrhea over 1 week (7 females and 7 males, 2-9 months of age) residing on a dog farm in August 2007. Species-specific PCR assay identified P. hominis 18S rRNA genes in 3 of the 14 puppies (1 female and 2 males; 1 aged 2 months and 2 aged 9 months). This phylogenetic analysis established that P. hominis belonged to the 1st clade, which is comprised of Bos taurus and Felines.

PURPOSE: This article attempted to examine how teeth for restoration is made in a clinical practice and utilize it as future educational material of teeth formation and basic data for additional research. MATERIALS AND METHODS: This experiment investigated the models sent to milling center for production of zirconia crowns. After scanned with Lava CAD/CAM System (3M ESPE, Seefeld, Germany), they are measured on 'ImageJ (version 1.32j, National Institutes of Health, USA)' program and compared and analyzed. Convergence angle from mesio-distal surfaces and bucco-lingual surfaces of each teeth are measured. Also, bucco-lingual diameter of the region lowered as much as 0.4 mm from incisal edge in anterior teeth except canines.(This measure is defined as the Peak 0.4) The analysis of data between each group was conducted by Windows SPSS statistic program, and was proved significant on 95% confidence level by independent t-test, one-way ANOVA and multiple analysis (Sheffe test). RESULTS: The mean value of convergence angle was 18.67degrees. It is ranked as molar (26.70degrees) > premolar (16.87degrees) > anterior teeth (14.81degrees) in the order of mesio-distal convergence angle; anterior teeth (22.32degrees) > molar (20.93degrees) > premolar (15.41degrees) in the order of bucco-lingual convergence angle. The mean value of Peak 0.4 was 1.18 mm. CONCLUSION: Convergence angle of abutment of zirconia all ceramic crown has difference depending on the location in the arch. Due to the nature of production of zirconia all ceramic crown, convergence angle of abutment and line angle finishing degree can have an effect on internal suitability of restoration.

BACKGROUND: The phosphoinositide 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) signaling axis has emerged as a novel target for cancer therapy. Agents that inhibit this pathway are currently under development for lung cancer treatment. In the present study, we have tested whether dual inhibition of PI3K/Akt/mTOR signaling can lead to enahnced antitumor effects. We have also examined the role of autophagy during this process. METHODS: We analyzed the combination effect of the mTOR inhibitor, temsirolimus, and the Akt inhibitor, GSK690693, on the survival of NCI-H460 and A549 non-small cell lung cancer cells. Cell proliferation was determined by MTT assay and apoptosis induction was evaluated by flow cytometry and terminal deoxynucleotidyl transferase dUTP nick end labeling assay. Autophagy induction was also evaluated by acridine orange staining. Changes of apoptosis or autophagy-related proteins were evaluated by western blot analysis. RESULTS: Combination treatment with temsirolimus and GSK690693 caused synergistically increased cell death in NCI-H460 and A549 cells. This was attributable to increased induction of apoptosis. Caspase 3 activation and poly(ADP-ribose) polymerase cleavage accompanied these findings. Autophagy also increased and inhibition of autophagy resulted in increased cell death, suggesting its cytoprotective role during this process. CONCLUSION: Taken together, our results suggest that the combination of temsirolimus and GSK690693 could be a novel strategy for lung cancer therapy. Inhibition of autophagy could also be a promising method of enhancing the combination effect of these drugs.
