OBJECTIVES: Schizophrenia manifests a variety of interindividual differences in therapeutic response to antipsychotics. This might be attributable to dopamine and serotonin receptors that a important target for various antipsychotics, and the D3 receptor(DRD3) alleles they carry. The purpose of our study was to investigate whether the plasma levels of homovanillic acid(HVA) and 5-hydroxyindoleacetic acid(HIAA), and the polymorphism of DRD3 can be held as a predictor of treatment response ni chronic schizophrenic patients. METHODS: Therapeutic response for 16 korean schizophrenia patient treated during 48 weeks were assessed by PANSS used as the clinical symptom rating scales. The levels of concentration of HVA and 5-HIAA were examined by HPLC at baseline and at 48 weeks. We classified the polymorphism of DRD3 receptor using amplifying by polymerase chain reaction(PCR). RESULTS: Neither concentrations of HVA and 5-HIAA nor genotype of dopamine 3 receptor were not significantly associated with the therapeutic response. But, the patients who has A1 alleles of DRD3 gene showed poor therapeutic responses. CONCLUSION: A1 allele of DRD3 gene is associated with poor prognosis of chronic schizophrenia.

BACKGROUND: Various hemodynamic changes occur during left ventriculography, such as myocardial depression, hypotension, peripheral circulatory changes, ECG changes(such as arrhythmias and conduction abnormalities) and anaphylactic reaction etc. These effects are somewhat caused by osmolality, ionic concentration of Na+, viscosity and molecular weight of contrast dye and underlying various heart disease itself during left ventriculography. We compared the hemodynamic differences between ionic(ioxaglate) and non-ionic(iopromide) low osmolar contrast agents during routine ventriculography. METHODS: In a prospective, randomized, double blind study of 124 patients underwent left ventriculography, we examined the various hemodynamic effects of the two contrast agents on left ventricle. All subjects were divided into 2 groups : ioxaglate and iopromide groups. Also, each agent was used in randomized double blind fashion in both groups ; normal control subjects(14 in ioxaglate group : 12 in iopromide group) and subjects whose ejection fraction less than 50%(12 in ioxaglate group : 16 in iopromide group). Left ventricular systolic pressure(LVSP), left ventricular end-diastolic pressure(LVEDP), maximum dP/dt, (dP/dt)/P ratio, peak - dP/dt and Tau were obtained immediately before and left ventriculography. RESULTS: 1) In total(normal+angina+MI) subjects of both groups, LVEDP(p<0.001) and maximum dP/dt(p<0.001) were increased and T(au) was reduced significantly(p<0.05). But LVSP(p<0.001) and peak - dP/dt(p<0.005) were increased significantly only in ioxaglate group. 2)In normal(control) subjects, there were no significant differences in both groups, except LVEDP that was increased by equal magnitude(p<0.001). 3) In subjects with ejection fraction less than 50%, there were no significant hemodynamic differences in both contrast agent groups bur LVEDP increased significantly in both groups(p<0.001). CONCLUSIONS: This present study showed that both ionic(ioxaglate) and non-ionic(iopromide) low osmolar contrast agents were very safe without any significant side effects except two agents caused an increase in LVEDP and did not show major differences between ioxaglate and iopromide contrast agents from a hemodynamic point of view. Two contrast agents tend to improve contractilities and diastolic properties of left ventricle since both caused an increase in maximum dP/dt and a reduce in Tau, in total subjects. This effect may be caused by cardiac compensation, probably because of osmolality, volume loading by contrast agents and secondary activation of sympathetic system immediately after injection of contrast agents. Thus, it is concluded that two ioxaglate and iopromide contrast agents amy be used safely in left ventriculography in patients with and without left ventricular dysfunction, with paying attention to an increase in LVEDP.

Zenker diverticulum is rare and symptoms of diverticulum are atypical. This is most commonly seen at the Killian's triangle. This is caused by altered motility, which results in abnormal intraluminal pressure and the pushing of the mucosa through weakness of the wall. Treatment is surgical via an endoscopic or external approach. Previous external approaches are associated with high com-plication rates and morbidity. We report a new external surgical approach using the gastrointestinal autostapler (GIA) instrument.

Background:
Reversal of neuromuscular blockade (NMB) at the end of surgery is important for reducing postoperative residual NMB; this is associated with an increased risk of postoperative pulmonary complications (PPCs). Moreover, PPCs are associated with poor prognosis after video-assisted thoracoscopic surgery (VATS) for lobectomy. We compared the effects of two reversal agents, sugammadex and neostigmine, on the incidence of PPCs and duration of hospital stay in patients undergoing VATS lobectomy.
Methods:
After VATS lobectomy was completed under neuromuscular monitoring, the sugammadex group (n = 46) received sugammadex 2 mg/kg, while the neostigmine group (n = 47) received neostigmine 0.05 mg/kg with atropine 0.02 mg/kg after at least the third twitch in response to the train of four stimulation. The primary outcome was incidence of PPCs. The secondary outcomes were duration of hospital stay and intensive care unit (ICU) admission.
Results:
There was no significant difference in the incidence of PPCs for both the sugammadex and neostigmine groups (32.6% and 40.4%, respectively; risk difference = 0.08; 95% confidence interval = [−0.12, 0.27]; P = 0.434). The lengths of hospital (P = 0.431) and ICU (P = 0.964) stays were not significantly different between the two groups.
Conclusions
The clinical use of sugammadex and neostigmine in NMB reversal for patients undergoing VATS lobectomy was not significantly different in the incidence of PPCs and duration of hospital and ICU stay.

To evaluate the effect of capsular tension ring on prevention of capsular opening reduction induced by CCC in Phacoemulsification with silicone intraocular lens implantation, we prospectively studied 60 patients (60 eyes)who were operated from Sept, 1997 to Jun, 1998 at our hospital.All patients had standardized Phacoemulsification, continuous curvilinear capsulorhexis, and intraocular lens implantation performed by the same surgeon.Patients were randomized into two groups based on capsular tension ring insertion.We compared uncorrected visual acuity (UCVA), spherical equivalent (SE), astigmatism and the data obtained by the Anterior Eye Segment Analysis System (EAS-1000), anterior chamber depth, IOL tilting, decenteration, and anterior capsule opening area at 1 week and 1, 3, 6 months after surgery.Two groups showed a similar pattern of change of UCVA, SE and astigmatism. There are no statistical significances in comparison of anterior chamber depth and IOL decenteration in two groups, but IOL tilting of group II is greater than that of group I at 6 months after surgery.The mean anterior capsular opening area at 1, 3, 6 months postoperatively was smaller than that of 1 week in two groups, but no statistical significances were observed in group II (1, 3, 6 months, P = or > .05).The mean percentage reduction of group I was significantly smaller than that of group II at 3 and 6 months (P<.05)after surgery.Capsular tension ring might prevent a contraction of capsular opening and might enhance the stability of IOL.

Isolated fourth(IV) ventricle in shunted patients has been reported with increasing frequency. Symptomatic isolated IV ventricular hydrocephalus in adults, however, has seldom been described. We report five such cases among total of 420 shunted cases in our institution from January 1992 to December 1995. The causes of initial hydrocephalus were postsurgical meningitis(SAH, teratoma and abscess of posterior fossa), tuberculous meningitis and neurocysticercosis of the IV ventricle. All cases were symptomatic with clinical findings related to posterior fossa lesions. Two patients developd symptoms in 2 months after V-P shunts and the others between 17 and 118 months after V-P shunts. These 5 patients required IV ventricular shunting. All patients improve postoperatively except one patient who developed 6th nerve palsy related to secondary irritation of the brainstem by the IV ventricular catheter. Inflammatory changes in the ependyma of both aqueduct of Sylvius, foramina Luschka and Magendi have been regarded as the most important factors in the development of the isolation of IV ventricle, especially in adults. It is generally recommended to shunt in cases of the adult symptomatic isolated IV ventricle. Alternative surgical techniques and prevention of such complications are discussed.

BACKGROUND/AIMS: To evaluate and select microRNAs relevant to acute myeloid leukemia (AML) pathogenesis, we analyzed differential microRNA expression by quantitative small RNA next-generation sequencing using duplicate marrow samples from individual AML patients. METHODS: For this study, we obtained paired marrow samples at two different time points (initial diagnosis and first complete remission status) in patients with AML. Bone marrow microRNAs were profiled by next-generation small RNA sequencing. Quantification of microRNA expression was performed by counting aligned reads to microRNA genes. RESULTS: Among 38 samples (32 paired samples from 16 AML patients and 6 normal marrow controls), 27 were eligible for sequencing. Small RNA sequencing showed that 12 microRNAs were selectively expressed at higher levels in AML patients than in normal controls. Among these 12 microRNAs, mir-181, mir-221, and mir-3154 were more highly expressed at initial AML diagnosis as compared to first complete remission. Significant correlations were found between higher expression levels of mir-221, mir-146, and mir-155 and higher marrow blast counts. CONCLUSIONS: Our results demonstrate that mir-221 and mir-181 are selectively enriched in AML marrow and reflect disease activity. mir-3154 is a novel microRNA that is relevant to AML but needs further validation.
