Abstract
Previous studies have demonstrated the autonomic dysregulation in patients with schizophrenia using electrophysiological methods, such as electrodermal measures and heart rate analysis.
Several theories have been proposed to explain the underlying mechanisms of schizophrenia and its autonomic function. Recently, the measurement of salivary alpha-amylase has been considered to be a useful tool for evaluating the sympathetic-adrenal-medullary (SAM) system. Psychosocial stress increases the release of salivary alpha-amylase.
Although some studies have evaluated salivary alpha-amylase under psychosocial stress, no studies have demonstrated the change in the salivary alpha-amylase (sAA) activity level in schizophrenic patients. We examined the relationship between sAA level and psychiatric state in patients with schizophrenia (n = 54) using a portable and rapid hand-held monitor to investigate sAA. The sAA activity in the patients was significantly higher than that in the control subjects (n = 55) (p < 0.01). The correlation between amylase level and psychiatric symptoms was highly significant (r = 0.37, p < 0.01).
These findings indicate that higher increases in sAA may indicate severe psychiatric symptoms. These results indicate a predominant role of the sympathetic nervous system in the secretion of sAA, together with parasympathetic withdrawal, under psychosocial stress.

Relevance of declines in serum human chorionic gonadotropin levels to the management of persistent ectopic pregnancy
ABSTRACT
Aim: To evaluate postoperative declines in serum human chorionic gonadotropin (hCG) levels (percentages of preoperative hCG levels) to rule out persistent ectopic pregnancy (PEP).
Methods: A retrospective study was conducted on 50 patients who underwent laparoscopic salpingotomy between April 1995 and March 2008. The postoperative course was divided into four periods: (period A: days 1–2; period B: days 3–4; period C: days 5–6; and period D: days 7–8), and the postoperative serum human chorionic gonadotropin declines in the PEP and control groups (successfully treated patients) were compared. A cutoff value of serum hcg decline to rule out PEP was established by receiver operating characteristic (ROC) analysis.
Results: Ten of the 50 patients (20%) were diagnosed with PEP. There were no differences in clinical findings or preoperative serum hCG levels between the two groups. From period C, the serum hCG decline in the control group was significantly greater than in the PEP group, and all individual serum hCG declines in the PEP group were outside the 95% confidence interval of the control group. Furthermore, analysis by ROC using a 14% decline in postoperative serum hCG as a cutoff revealed that the specificity and sensitivity of the test were equal to 100% from period C.
Conclusion: Declines in serum hcg during period C (days 5–6) constitute an important marker of the presence or absence of PEP. Decisions regarding a second intervention for PEP should be made by this time postoperatively.

Efficacy and safety of sorafenib in patients
Efficacy and safety of sorafenib in patients with advanced hepatocellular carcinoma (HCC): Asia-Pacific (AP) trial subgroup analyses by baseline transaminase (ALT/AST)/-alpha fetoprotein (AFP) levels
Journal of Clinical Oncology, 2009 ASCO Annual Meeting Proceedings (Post-Meeting Edition).Vol 27, No 15S (May 20 Supplement), 2009: 4590
Background: Results of the phase III, randomized, double blind, placebo-controlled AP trial demonstrated that sorafenib is effective and safe for the treatment of advanced HCC in patients from the AP region (Cheng et al, Lancet Oncol, 2009). Hepatic function influences treatment as a measure of organ damage and tumor stage. We performed subset analyses of the AP study dataset according to baseline hepatic function, as indicated by levels of ALT/AST and AFP.
Methods: Patients (N=226) with advanced HCC, ECOG PS 0–2, Child-Pugh class A, and no prior systemic therapy were randomized 2:1 to receive sorafenib 400 mg BID or placebo. Endpoints included overall survival (OS), disease-control rate (DCR; defined as complete/partial response or stable disease by RECIST, maintained for 28 days from first demonstration of response), time to progression (TTP) and safety. Patients were grouped by baseline levels of ALT/AST (normal, mild, or moderate) and AFP (normal or abnormal).
Results: Median TTP, OS and DCR by subset are shown in the table. The most common grade 3/4 adverse events in the sorafenib populations were hand-foot skin reaction and diarrhea.
Conclusions: Sorafenib was effective and safe in patients from the AP region with advanced HCC within a broad range of baseline hepatic enzyme and AFP levels. These results suggest that sorafenib is an effective treatment for HCC, irrespective of baseline ALT/AST or AFP levels

Department of Gynecology and Obstetrics, Tehran University/ Medical of Science, Iran.
BACKGROUND: Fetal growth restriction (FGR) is surprisingly common with placental dysfunction occurring in about 3% of pregnancies and despite advances in obstetric care, FGR remains a major problem in developed countries. AIM: The purpose of this study is to find out the predictive value of amniotic fluid high sensitive C-reactive protein (hs-CRP), ferritin , and lactate dehydrogenase (LDH) for FGR.
MATERIALS AND METHODS: This prospective strategy of this study has been conducted on pregnant women who underwent genetic amniocentesis between 15th and 20th weeks of gestation. All patients were followed up on until delivery. Patients with abnormal karyotype and iatrogenic preterm delivery for fetal and maternal indications were excluded. The samples were immediately sent to laboratory for cytogenetic and biochemical examination. Non-parametric tests and receiver-operator characteristic curve analysis were used for statistical purpose.
RESULTS: A significant correlation between incremental amniotic fluid alpha fetoprotein (alphaFPr) and LDH levels and FGR at gestational weeks 15th-20th was found out. We also found an optimum cut-off value> 140 IU/L for the amniotic fluid LDH concentration with a sensitivity of 87.5% and a specificity of 82.4% for the prediction of FGR.
CONCLUSION: Once the LDH value is confirmed, it could serve as a prediction factor for FGR at the time of genetic amniocentesis at gestational weeks 15-20.

Recombinant human albumin as protein source in culture media used for IVF
Oocytes obtained from 85 women undergoing IVF/intracytoplasmic sperm injection (ICSI) treatment were randomly selected for culture in media containing either human serum albumin (HSA), (n = 42) or recombinant human albumin (rHA), (n = 43). At the time of transfer, the two embryos with the overall best morphology were selected on day 2, 3 or 5. Comparable rates of fertilization, cleavage, blastocyst formation and implantation were observed in both groups. The frequency of pregnancy and early pregnancy loss were also equal. It is concluded that culture media containing rHA seem to produce embryos of high quality comparable to media containing HSA. Therefore, rHA may replace HSA as a protein source in culture media for IVF and may reduce risks of prion contamination and transmission of plasma derived impurities.

Prevalence of metabolic syndrome increases with the increase in blood levels of gamma glutamyltransferase and alanine aminotransferase in Japanese men
BACKGROUND: Gamma glutamyltransferase ( GGT ) or alanine aminotransferase ( ALT) is reported to be an independent risk factor of diabetes and cardiovascular disease and proposed as a component of metabolic syndrome (MS). However, there are few studies examining the direct association between MS and Gamma glutamyltransferase or alanine aminotransferase in Japanese men and women.
METHODS: Direct associations between GGT or ALT and MS defined by revised NCEP criteria for Japanese and between GGT or ALT and Japanese MS (JMS) defined by the Examination Committee for the Criteria of Metabolic Syndrome were examined using medical check-up data from 1,880 men and 1,079 women.
RESULTS: The prevalence of MS and JMS was significantly higher in subjects with the highest quartile of GGT or ALT than the subjects with the lowest quartile of GGT or ALT (p<0.0001 in men and p<0.0001 for MS and p<0.001 for JMS in women). The optimal cutoff points of GGT and ALT for diagnosing MS or JMS were 42 U/L or 41 U/L, respectively for GGT and both 25 U/L for ALT in men and 21 U/L or 23 U/L, respectively for GGT and 20 U/L or 25 U/L, respectively for ALT in women.
CONCLUSION: The prevalence of MS and JMS increases with the increase in blood levels of GGT or ALT even through the normal range of GGT or ALT in Japanese men and women.

Analysis of urobilinogen and urine bilirubin for intra-abdominal injury in blunt trauma patients
OBJECTIVE: To determine the point prevalence of urine bilirubin, urine hemoglobin and urobilinogen in blunt trauma patients, and to evaluate its utility as a screening tool for intra-abdominal injury.
METHODS: Data analysis of 986 consecutive trauma patients of which 698 were adult blunt trauma patients. Five-hundred sixteen subjects had a urinalysis and a CT scan of the abdomen/pelvis or exploratory laparotomy. We reviewed initial urinalysis results from trauma patients in the emergency department (ED) for the presence of urine hemoglobin, uroblinogen and urine bilirubin . Computed tomography (CT) scan results and operative reports were reviewed from the trauma registry for evidence of liver laceration, spleen laceration, bowel or mesenteric injuries.
RESULTS: There were 73 injuries and 57/516 patients (11%) with intra-abdominal injury. Urinalysis was positive for urobilinogen in 28/516 (5.4%) patients, urine bilirubin in 15/516 (2.9%) patients and urine hemoglobin in 313/516 (61%) patients. Nineteen/forty-seven (4%) subjects had liver lacerations, 28/56 (5%) splenic lacerations, and 15/5 (3%) bowel or mesenteric injury.
Comparing the proportion of patients that had urobilinogen detected in the group with and without intra-abdominal injury, 8/28 (29%) subjects with urobilinogen, 5/15 (33%) subjects with bilirubin and 47/313 (15%) subjects with urine hemoglobin were found to have liver lacerations, spleen lacerations, or bowel/mesenteric injuries. Preexisting liver or biliary conditions were not statistically associated with elevation of urine bilirubin, urine hemoglobin or on initial urobilinogen urinalysis after blunt abdominal trauma. Point prevalence for urobilinogen, urine bilirubin and urine hemoglobin are 5.43% (28/516), 2.91% (15/516) and 60.7% (313/516) respectively.
CONCLUSIONS: The utility of the initial routine urinalysis in the ED for adult blunt abdominal trauma patients should not be used as a screening tool for the evaluation of intra-abdominal injury.
