BACKGROUNDS: There have been controversies about the association between essential tremor (ET) and Parkinson's disease. To examine the nigrostriatal dopaminergic neurons in patients with ET, we measured the striatal dopamine transporter levels with [123I] N-(3-iodopropene-2-yl)-2?-carbomethoxy-3?-(4-chlorophenyl) tropane(IPT) single photon emission computed tomography (SPECT). METHODS: This study included nine patients with postural tremor, six patients with postural and rest tremor, 11 patients with idiopathic Parkinson's disease, and 21 age matches controls. Using triple headed gamma camera, brain SPECT scans were performed at 115 and 120 minutes after the injection of 6.23?1.37mCi(range 5-10mCi) of I123 labeled IPT. We averaged two images. Regions of interest were drawn on the middle set image at the level of basal ganglia (BG) for each subject. Amounts of striatal dopamine transporter were measured by calculating the ratio between the average counts of the basal ganglia minus occipital cortex (OCC) and the counts of the OCC((BG-OCC)/OCC). RESULTS: The mean of (BG-OCC)/OCC ratios of 9 isolated postural tremor patients (3.60?0.83) was not statistically different from that of the controls (P>0.05). However, the mean of (BG-OCC)/OCC ratios of 4 patients with postural and rest tremor (2.61?0.18) was significantly lower than that of the controls (P<0.01). Four of the six patients with postural and rest tremor had mean ratios lower than 2.0 standard deviations from the mean of the controls. CONCLUSION: In their later clinical courses, some patients with postural tremor may develop rest tremor in association with a damage in the nigrostriatal dopaminergic system.

PURPOSE: The purposes of this study were to evaluate symptom experience and quality of life (QOL) and to identify the predictors of QOL among breast cancer survivors. METHODS: A cross-sectional study was conducted on 200 disease-free breast cancer survivors at two hospitals between December 2007 and July 2008. Functional Assessment of Cancer Therapy Scale-B, Memorial Symptom Assessment Scale-short Form and The Linear Analogue Self Assessment Scale were used to assess symptom experience and QOL in these patients. Data were analyzed using the Pearson correlation, t-test, ANOVA, and stepwise multiple regression with SPSS/WIN 12.0. RESULTS: The mean score of QOL for breast cancer survivors was 95.81 (+/-18.02). The highest scores among physical and psychological symptoms were sexual interest and anxiety. Year since treatment completion was significantly associated with QOL in sociodemographic variables. Physical and psychological symptoms have a significant negative association with QOL. The results of the regression analyses showed that physical and psychological symptoms were statistically significant in predicting patients' QOL. CONCLUSION: Symptom experience and QOL are essential variables that should be acknowledged when delivering health care to breast cancer survivors. More attention to the reduction and management of psychological distress could improve QOL among breast cancer survivors.

To determine whether angiotensin-converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism is associated with the development and clinical features of systemic sclerosis (SSc) in Korean, we studied seventy two Korean patients with SSc fulfilling the ACR preliminary classification criteria. The controls were 114 healthy, disease free Koreans. ACE I/D genotypes were determined by PCR method using oligonucleotides. Sixty eight patients (94.4%) were women and age at diagnosis was 43.5+/-12.6 yr old (mean+/-SD). Thirty nine patients (54.2%) had a diffuse type of SSc. There were no statistical differences in the frequencies of all ACE I/D genotypes and D allele between patients and controls, and neither between diffuse and limited types of SSc. ACE I/D gene polymorphism was not associated with the development of SSc in Korea. The investigation for the pathogenesis of SSc requires more studies about the role of other candidate genes such as endothelin, TGF-beta, nitric oxide, or angiotensin II receptor in addition to the ACE genes.

OBJECTIVE: This study was conducted in order to investigate predictors of smoking cessation in outpatients. METHOD: Subjects were 401 adult smoking patients who saw their doctors in the outpatient setting at a university hospital, regardless of their willingness of otherwise in smoking cessation. Physicians delivered a brief, stop smoking prompt to all patients who smoked one or more cigarettes a day. Then they referred to on-site counselors who provided a brief, nurse assisted intervention with a survey to a randomly assigned intervention group (200 smoking patients), whom the counselors telephoned later to prevent relapse or promote the motivation to quit, or gave only a survey to a control group (201 smoking patients). After at least 5 months, self-reported current smoking cessation was confirmed later using cut-off values of 7 ppm or less in expired alveolar air after breath holding portable CO analyzer. RESULTS: After 5 months, subjects in the intervention group were 1.56 times (95% C.I. 0.89-2.73) more likely to quit smoking than those in the non-intervention group (14.0% vs. 9.0%). Willingness to quit smoking in a month, scheduled admission in a month, self efficacy score and FTND (Fagerstrom Test for Nicotine Dependence) score were all significantly related with smoking cessation. In stepwise multiple logistic regression, previous attempts to quit smoking were significant instead of self efficacy score. In the intervention group who had willingness to quit smoking in a month (132 smoking patients), FTND score, whether quit date was today, and whether quit promise paper was submitting were all significantly related with smoking cessation. In stepwise multiple logistic regression, scheduled admission in a month and whether quit date was today were significant predictor variables. Smoking cessation treatment should be tailored to individual smoking patients considering these predictors.

PURPOSE: In a preliminary series of 36 eyes with partial nasolacrimal duct obstruction, the types of dacryoscintigraphy result were classified and the results of silicone tube intubation were analysed. METHODS: The results of dacryoscintigraphy, performed in 36 eyes of 29 patients with partial nasolacrimal duct obstruction, were classified into the following 3 types: pre-lacrimal sac type, proximal nasolacrimal duct type and distal nasolacrimal duct type. Punctoplasty accompanied by silicone tube intubation was conducted selectively. RESULTS: In dacryoscintigraphy, symptoms improved in 6 eyes among 6 in distal nasolacrimal duct type (100%), 14 eyes among 18 in proximal nasolacrimal duct type (77.8%) and 8 eyes among 12 in pre-lacrimal sac type (66.7%). CONCLUSIONS: We conclude that dacryoscintigraphy predicts the results of silicone tube intubation. Furthermore, silicone tube intubation was effective in proximal nasolacrimal duct type and distal nasolacrimal duct type, but less effective in pre-lacrimal sac type of partial nasolacrimal duct obstruction.

OBJECTIVE: The Apgar score has long been used to determining birth asphyxia and assessing early neonatal status and long-term outcome. Unfortunately, some components of this system depend upon subjective interpretation. Also, although, low Apgar score, Most of newborns are relatively healthy. The objective of our studt is attempt to assure the linical significance of Apgar score and umbilical cord blood gas analysis on assessing status of uncomplicated preterm infants delivered vaginally. METHODS: The present study was performed in attempt to compare umbilical arterial blood gas values for uncomplicated preterm infants delivered vaginally with low 1 and 5 minutes Apgar score (<7) with those for term or preterm infant with normal 1 and 5 minutes score (>7), each other, The present study included 82 uncomplicated term infants delivered vaginally and 24 preterm infants. Inclusion criteria of our study is as follows: 1) Singleton neonate with vertex presentation, 2) No congenital malformation, 3) Infants whose mother had no obstetrical and medical complications, 4) Immediately after delivery, umbilical arterial blood was sampled, before first breathing of neonate, 5) Infants applied Apgar score at I minute and again 5 minutes after birth, and 6) Infants whose mothers gestational age was estimated by ultrasonography during first-trimester of pregnancy. The statistical analysis was performed by Mann-Whitney U test and Fishers exact test. RESULTS: 1) There was no significant difference in umbilical arterial blood gas values between uncomplicated preterm infants delivered vaginally with low 1 and 5 minutes Apgar score (<7) and term infants with normal score (>7). 2) There was no significant difference in umbilical arterial blood gas values between uncomplicated preterm infants delivered vaginally with low 1 and 5 minutes Apgar score (<7) and preterm infants with normal score (>7). 3) There was significant difference in frequency of lower Apgar score (<7) between term (2%[2/82]) and preterm infants (38%[9/24]), but not in frequency of acidemia (defined as less than pH 7.2) (28%[23/82] Vs 33%[8/24]). CONCLUSION: The Apgar score is not a reliable indieator of well-being in preterm neonate. We recommend umbilical arterial blood sampling at delivery of preterm infant with low Apgar score, because umbilical cord blood gas indices on objective means of assessing birth status of the newbarn and more useful than Apgar score in ruling out birth asphyxia.

A 48 year old woman was diagnosed with a huge cystic mass in her abdominal cavity. She complained of significant abdominal discomfort due to the mass. The abdominal computed tomography revealed a giant multi-lobulated mass, measuring 26x12 cm in size, adjacent to the lesser curvature of the stomach. In the operation field, the mass was found to originate from the lesser omentum, including the right and left gastric vessels and the vagus nerves, and to invade the lesser curvature of the stomach. For curative resection, distal subtotal gastrectomy with mass excision followed by gastroduodenostomy were performed. This mass was pathologically diagnosed to be a mesenteric cystic lymphangioma; in fact, the largest ever reported. The patient had no complications during the postoperative period and was discharged from the hospital on the seventh day after surgery.

BACKGROUND/AIMS: Small-caliber esophagogastroduodenoscopy (scEGD) was developed to facilitate unsedated EGD, and has many advantages over sedated EGD in terms of costs and complications. This study compared the feasibility and tolerance of scEGD with unsedated conventional EGD (cEGD), and examined the effect of the endoscopic diameter on the patients' tolerance. METHODS: A total of 114 patients who were referred for a diagnostic EGD was randomly allocated to undergo either scEGD (GIF XP260, Olympus, diameter 6.5 mm; n=57) or cEGD (GIF XQ240, Olympus, diameter 9.0 mm; n=57). After EGD, the patients and endoscopists completed questionnaires on the level of discomfort, satisfaction and acceptance of the examination. RESULTS: Patients in the scEGD group reported significantly less discomfort (choking, pain and nausea) and more overall satisfaction than those in the cEGD group. Patients in the scEGD group were more willing to choose the same procedure again if medically indicated. According to multivariate analysis, the ultrathin endoscopic diameter itself was positively associated with the increased patients' satisfaction (odds ratio 3.07, p=0.003). CONCLUSIONS: scEGD has comparable feasibility and accuracy but is more tolerable than cEGD. scEGD may have a role in clinical practice by minimizing the level of discomfort during unsedated EGD.

Lung cancer metastases can occur in almost any organ. However, metastasis of small cell lung cancer to the pancreas is rare. Moreover, not all cases present with clinically diagnosed pancreatitis. We recently treated a patient with small cell lung carcinoma that invaded the pancreatic duct causing acute pancreatitis. Generally, the treatment for tumor-induced acute pancreatitis is initially supportive followed by aggressive chemotherapy or surgery. If the patient can tolerate the insertion of an endoscopic intrapancreatic stent, this is performed in addition to chemotherapy and surgery; this approach offers a safe and effective treatment modality for such patients.

PURPOSE: Despite of the effectiveness of androgen deprivation therapy for prostate cancer, it progress to androgen independent prostate cancer (AIPC) after various periods of time. The objective of this study was to analyze the clinical and pathological variables that predict progression to AIPC after combined androgen blockade (CAB). MATERIALS AND METHODS: We retrospectively reviewed the medical records of 343 patients who were treated with CAB for prostate cancer. Binary logistic regression test was used to analyze the independent predictors for the progression to AIPC. The time to AIPC, according to variables, was assessed by the Kaplan-Meier method and the variables were compared using the Log-Rank test. RESULTS: The mean follow-up was 42.1 months (range: 12-120). Seventy seven patients (33.3%) experienced progression to AIPC at a median of 20.2 months (range: 6-72). On univariate analysis, the percentage of positive prostate biopsies, the Gleason score, the T stage, the extent of bone metastasis, lymph node metastasis, the pretreatment PSA level, the nadir PSA and the PSA level at 3 and 6 months all had a significant relationship with the progression to AIPC. The receiver operating characteristic curve analysis for the nadir PSA showed that the optimal cut-off point to predict progression to AIPC was 0.5ng/ml with an area under curve of 0.769. A multivariate analysis demonstrated that the Gleason score (>7), the nadir PSA (>0.5ng/ml), and the PSA level at 6 months (>4.0ng/ml) were significantly correlated with the progression to AIPC. CONCLUSIONS: This study suggested that Gleason score, the nadir PSA and the PSA level at 6 months were independent variables to predict progression to AIPC after CAB. The PSA level at 6 months may be the most accurate variable to predict progression to AIPC.
