Mental health first aid training of the public in a rural area: a cluster randomized trial [ISRCTN53887541]

Background  

A Mental Health First Aid course has been developed which trains members of the public in how to give initial help in mental health crisis situations and to support people developing mental health problems. This course has previously been evaluated in a randomized controlled trial in a workplace setting and found to produce a number of positive effects. However, this was an efficacy trial under relatively ideal conditions. Here we report the results of an effectiveness trial in which the course is given under more typical conditions.     

Early detection of abnormalities in partial epilepsy using magnetic resonance

The incidence of brain abnormalities determined by magnetic resonance in 30 consecutive children presenting with intractable complex partial seizures is reported. Images were optimised to visualise the hippocampus and cortical grey matter. Abnormalities of the hippocampus or temporal lobe were seen in all 19 children with clinical features of temporal lobe epilepsy and in six of the seven children with clinically unlocalised epilepsy. By contrast, in the four children with a clinical diagnosis of extratemporal epilepsy, no temporal or hippocampal abnormalities were seen. Generalised cortical abnormalities of uncertain significance were found in a total of 14 children from all groups. The identification of focal brain abnormalities using optimised magnetic resonance imaging enables early non-invasive assessment of children with intractable seizure disorders and the identification of patients for whom epilepsy surgery may be appropriate. It may also lead to a better understanding of the structural basis of intractable epilepsy, and thereby contribute to early treatment decisions.     

Artificial renal and liver support in a severe hepatorenal syndrome of childhood

This case report describes a special management approach in a child aged 4.5 years with a severe form of hepatorenal syndrome in which the final diagnosis was familial hemophagocytic lymphohistiocytosis (FHL). The patient presented with grade IV hepatic coma and acute renal failure (ARF). While the diagnosis was difficult at the time of admission, as well as during acute treatment, artificial liver support was established for elimination of bilirubin and other metabolic by-products by using charcoal column plasma perfusion (CCPP) and bilirubin-adsorbing resin column plasma perfusion (BRCPP). Serum levels of bilirubin showed a notable decrease after each of the four treatment sessions. Additional artificial renal function replacement by continuous arteriovenous hemofiltration and hemodialysis (CAVH, CAVHD, respectively) had a marked lowering effect on urea and creatinine serum concentrations. Both artificial liver and renal support contributed to the general clinical improvement and survival of the patient. Further experience in these therapies will be needed to establish better prognosis in such fatal or acute similar conditions.     

Twin and singleton growth patterns compared using US

Sonography has been used widely in the evaluation of singleton fetal growth. Twin gestations, however, have received less careful attention. In a statistical study of 103 twin pregnancies, the growth patterns of twin biparietal diameter (BPD), fetal femur length (FFL), and abdominal circumference (AC) were compared with those of singletons. The results of the study revealed a decrease in twin BPD growth after 31 to 32 weeks of gestation relative to singletons. Twin AC growth rate decreases after 32-33 weeks of gestation relative to singletons, but the twin FFL growth pattern does not deviate from that of singletons throughout gestation. Because of the significant difference in growth patterns of BPD and AC between twins and singletons in our population, new growth charts for twin BPD and AC are proposed.     

Are classifications of proximal radius fractures reproducible?

Background  

Fractures of the proximal radius need to be classified in an appropriate and reproducible manner. The aim of this study was to assess the reliability of the three most widely used classification systems.     

腐胺对大鼠肝损害的影响

大鼠腹腔给腐胺琥珀酸盐后,由门静脉到达肝脏。在肝组织中的多胺含量采用高效液相色谱法测定。实验证明,腐胺对半乳糖胺引起的大鼠SGPT升高有明显的降低作用,使血清胆红素量减少,相应的肝组织病变减轻。也能使病鼠肝组织中的内源性腐胺水平显著下降,并提高核酸含量。     

Bronchogenic carcinoma: staging with MR compared with staging with CT and surgery

Thirty-three patients suspected of having bronchogenic carcinoma were studied prospectively using magnetic resonance (MR). In this group, 30 underwent examination with computed tomography (CT), 15 underwent thoracotomy, six had mediastinal biopsy procedures performed, and eight underwent bronchoscopy. MR studies, which included transaxial spin-echo imaging (TR, 0.5 and 2.0 sec; TE, 28 and 56 msec) of all patients and sagittal or coronal imaging of 18, were performed without knowledge of CT findings, using only plain radiographs as a guide. CT and MR studies were interpreted separately. CT and MR provided comparable information regarding the presence and size of mediastinal lymph nodes. MR better discriminated mediastinal nodes from vascular structures. However, in two of 11 patients who had multiple mediastinal lymph nodes that were normal in size at CT examination and surgery, MR suggested a confluent abnormal mass, probably because of its poorer spatial resolution. MR was superior to CT in showing enlarged hilar lymph nodes, but CT was better for demonstrating bronchial abnormalities. In three of four patients who had a proved hilar mass with distal obstructive pneumonia, MR (TR, 2.0 sec) helped distinguish between the mass and collapsed lung.
