Interhemispheric multiloculated ependymal cyst with dysgenesis of the corpus callosum: a case in a preterm fetus

Introduction The authors report a case of interhemispheric ependymal cyst accompanied with agenesis of the corpus callosum in a fetus. Discussion Routine ultrasound and subsequent magnetic resonance imaging of a 20-year-old woman at 33 weeks and 1 day of gestation detected a large interhemispheric cystic lesion in the fetal cranial cavity. Caesarian section was carried out at 36 weeks because of the progressive enlargement of the fetal head. The cyst was multiloculated and a cyst peritoneal shunt placement resulted in collapse of the drained cyst components followed by enlargement of others. After wrack-a-mole-like shunt revisions, open surgery was performed at the age of 2 years. Cyst walls were fenestrated and the cavities were communicated with each other and eventually with the lateral ventricle. Pathological diagnosis of the cyst wall was ependymal cyst. The boy is now 3 years old, and growing without apparent developmental delay or recurrence. Current concept and management policy of the interhemispheric cyst accompanied with agenesis of the corpus callosum is reviewed.     

Intraoperative blood loss is a risk factor for complications in donors after living donor hepatectomy.

Complications in a donor are a distressing but inevitable occurrence, since graft procurement is a major undertaking. Although the technique for procurement has some similarities to hepatic resection, a donor is very unlike a patient with malignancy. The risk factors identified in these patients cannot be extrapolated to donors. Donor hepatectomy carried out from June 1995 to March 2005 in Chang Gung Memorial Hospital, Kaohsiung Medical Center was reviewed with the aim of identifying risk factors for complications. There were 204 living donor liver transplants, with 205 donor hepatectomies, as 1 living donor liver transplantation was a dual graft. Ten donors (4.88%) suffered complications. There was no difference in terms of age, gender, body weight, operation, and parenchymal time between those who had complications and those who did not. There was also no difference in liver function tests between the 2 groups of donors, but the total bilirubin was significantly higher in donors with complications. The graft weight and remnant liver volume were also similar. The proportion of donors with fatty liver was the same between the 2 groups. The mean blood loss in donors with complications was 170 +/- 79 mL, and that for donors without complications was 95 +/- 77 mL. There was a statistically significant greater blood loss in donors with complications (P < 0.05). The number of segments removed in donors with complications was also higher compared to donors without complications (P < 0.03). Using multivariate analysis, intraoperative blood loss and the number of segments removed were found to be independent risk factors for donor complications. Intraoperative blood loss during graft procurement must be kept low to minimize complications in donors.

Precursors of schizophrenia

Several likely precursors of schizophrenia have been identified. These range from possibly causative features, such as exposure to perinatal insults, to features that are the effects of an underlying vulnerability, such as abnormal childhood behaviors. Unfortunately none of these precursors is specific enough to be used in identifying individuals for targeted preventive treatment. A more useful strategy is to combine risk factors for psychotic disorders in a population seeking help for psychiatric problems. Thus, individuals who are possibly prodromal are identified. Research into this group has found high rates of onset of psychotic disorders, particularly schizophrenia, within a short time frame. Preliminary treatment trials suggest that symptoms can be reduced and psychosis onset possibly delayed or averted.

类风湿性关节炎患者氧化还原物水平的测定

OBJECTIVE: To examine the oxidation or reduction products in patients with rheumatism arthritis (RA), and investigate the relationship between oxidation or reduction products and occurrence and development of RA. METHODS: The serum levels of total ascorbic acid (TAA), dehydroascorbic acid (DHAA)/TAA, vitamin E, advanced oxidation protein products (AOPP) and malondialdehyde (MDA) were detected by high-performance liquid chromatography with electrochemical detection in 83 RA patients and 30 healthy adults. Correlation analysis of AOPP, MDA and hs-CRP was performed. RESULTS: Compared with normal control group, significantly higher serum MDA, DHAA/TAA, and AOPP levels were detected in RA patients (P<0.05), but vitamin E showed no significant difference (P<0.05). Linear regression analysis showed that MDA (P<0.01) was positively but AOPP (P>0.05) negatively correlated to hs-CRP. CONCLUSIONS: Oxidation or reduction products in serum of RA patients increases significantly, which may be an important mechanism for the occurrence and development of RA. Serum AOPP and MDA levels can reflect the oxidation status in RA patients.     

The Application of Compatible Points

Point compatibility plays a very important role in clinical treatment, and proper compatible application of points can directly influence the therapeutic effects. Only by knowing the functions of points well, can the proper pair of point be prescribed. As stated in Chinese ancient classics, “Functions of points must be carefully considered before needling” and “Much care and thought should be given to selecting points when various diseases are treated with acupuncture.” Dr. Guo Shouyun, a veteran TCM physician, always pays great attention to the combination of points in her acununcture clinical nractice.
