The implications of subclinical hypothyroidism (SCH) are many amongst which the most important is progression to overt hypothyroidism. Other debatable aspects are its association with cardiovascular risk, neuromuscular and psychiatric dysfunction, increased predisposition to developing metabolic syndrome and an underlying pro-inflammatory state. We aimed to study the lipid profile, lipoprotein(a) [Lp(a)] and hsCRP levels and insulin resistance in a group of patients with SCH in a referral hospital and see if any significant differences exist between them and euthyroids. This is a case–control study where the selection of controls and cases was based on the thyroid profile. Subjects were selected on their visit to clinical biochemistry lab for thyroid function tests. 33 euthyroids were taken as controls (Group I) and 38 patients comprising of subclinical hypothyroids were grouped as cases (Group II). Serum thyroid stimulating hormone (TSH) was in the range of 0.5–5.0 mIU/L for euthyroids and for subclinical hypothyroids the concentration of TSH was more than 5 mIU/L. The concentration of tri-iodothyronine (T3) and thyroxine (T4) were in normal reference range in both the groups. Individual lipid profile parameters failed to show a significant p value between cases and controls. The LDL/HDL ratio was highly significant (p value < 0.0001) and hsCRP was also statistically between the two groups (p value = 0.0054). Lp(a) and insulin resistance did not differ significantly. SCH is a common disorder that frequently progresses to overt hypothyroidism. This study underlines the importance of LDL/HDL ratio rather than measurement of individual lipid profile parameters in bringing to light the dyslipidemic state associated with SCH. Moreover the use of hsCRP to detect an underlying pro-inflammatory state in SCH can also be emphasized.  相似文献

In this article, an inclusive treatment package for children with ADHD, The ADHD Classroom Kit (Kit), is described. Components of the Kit are categorized in three areas: consequences for appropriate behavior, consequences for inappropriate behavior, and peer-mediated interventions. The empirical rationale for each component of the Kit is discussed. Also, a case study of a 6-year-old girl (Carol) with reported disruptive behavior problems is presented as preliminary data supporting the Kit's effectiveness. An A-B-A reversal design was used in Carol's classroom. Mean frequencies of appropriate behavior were 61.3% (baseline), 78.5% (Kit), and 70.7% (reversal). In addition, mean frequencies of on-task behavior were 76.2% (baseline), 87.8% (Kit), and 82.5% (reversal). Implications for future research and practice with the Kit are addressed. © 1998 John Wiley & Sons, Inc.  相似文献

BACKGROUND: There is a diagnostic dilemma when a child presents with rib fractures after cardiopulmonary resuscitation (CPR) where child abuse is suspected as the cause of collapse. We have performed a systematic review to establish the evidence base for the following questions: (i) Does cardiopulmonary resuscitation cause rib fractures in children? (ii) If so, what are the frequency and characteristics of these fractures that may help to distinguish them from rib fractures caused by physical abuse? METHODS: We performed a literature search of original articles, references, textbooks, and conference abstracts, published in any language from 1950 to 1 October 2005. Articles were identified from ASSIA, Caredata, Medline, Ovid Medline in Process, ChildData, CINAHL, Embase, ISI Proceedings, SIGLE, Science Citation Index, Social Science Citation Index, and TRIP databases. We included all studies that addressed rib fractures and CPR in children less than 18 years, and excluded review articles, expert opinion, consensus guidelines, and studies that were significantly methodologically flawed on critical appraisal. Each study underwent two independent reviews (with a third review if there was disagreement). Each reviewer used standardized criteria for study definition, data extraction, and critical appraisal, to determine the quality of the study and to establish if it met the inclusion criteria of this systematic review. FINDINGS: Of the 427 studies reviewed, 6 were included: 1 case control, 4 cross-sectional, and 1 case series. These represent data on 923 children who underwent CPR. Three children sustained rib fractures as a result of resuscitation; all three of these had fractures that were anterior (two mid-clavicular and one costo-chondral). We did not find any child in the literature who had a posterior rib fracture due to CPR. Resuscitation was performed variably by both medical and non-medical personnel. CONCLUSION: Rib fractures after cardiopulmonary resuscitation are rare. When they do occur, they are anterior and may be multiple. As the studies performed to date did not use the most sensitive techniques for detecting rib fractures, further prospective studies of children would be valuable to provide additional clarification on this question.  相似文献

Light chain disease is a variant of multiple myeloma in which the malignant population of marrow cells produces free monoclonal light chains but no heavy chain or complete immunoglobulin. The monoclonal light chains are small enough to be freely filtered by the kidneys and become Bence–Jones protein. Light chain disease comprises about 18% of multiple myeloma patients. Here we present a case report of a 38-year-old man who initially presented with complaints of pain in back and low grade fever off and on. He was found to have collapse of D9 and D12 vertebrae along with ascites and right pleural effusion and massive proteinuria. Multiple myeloma was considered as a differential diagnosis based on the investigations but eventually the patient was lost to follow up. This case is reported here as the light chain variant of multiple myeloma leading to deposition disease is less commonly reported and presents considerable difficulties in diagnosis.  相似文献

The hypoglycemic effect of the aqueous extract ofAbroma augusta (Family: Steculiceae) was studied in normal as well as alloxan diabetic rats. Treatement of diabetic rats with 4 ml (4gm dry weight) of agueous extract ofA. augusta for 16 weeks resulted in gradual but significant fall in fasting blood glucose and improvement in glucose tolerance. Serum total and LDL cholesterol and triacylglycerol which increased in diabetic rats showed improvement. These results show that the water extract ofA. augusta has both hypoglycemic and hypocholesterolemic effects.  相似文献

This article presents a model for research on the effects of school organizational heath factors on primary school academic achievement in Trinidad and Tobago. The model can be applicable for evaluating schools in other developing countries. As proposed, the model hypothesizes relationships between external factors (exogenous variables), school-level factors (endogenous variables), and school outcomes (student achievement and positive school climate). The endogenous variables are sub-scales of school organizational health. They include principal leadership, psycho-social environment, school–home–community relationships, teacher characteristics, curriculum quality, and school culture. These subscales are partially influenced by the Organizational Health Inventory OHI (Hoy and Feldman, 1987) and by school health indices set forth by the World Health Organization (1996). It is hoped that this school organizational health model can provide a conceptual tool for formulating a more comprehensive measure of healthy schools.  相似文献

Hyperkalemia is a life threatening electrolyte derangement that must be recognized and treated quickly. Pseudohyperkalemia is defined as a difference between serum and plasma potassium concentration of more than 0.4 meq/L with serum values on the higher side when both the samples are obtained at the same time, remain at room temperature and are tested within 1 h of sample collection. Given the implication of basing medical decisions on falsely elevated potassium levels, timely identification of the entity of pseudohyperkalemia and differentiating it from true hyperkalemia becomes utmost important. Here we present a case report of a 36 year old female admitted with a provisional diagnosis of pyrexia of unknown origin with hepatosplenomegaly and anaemia under evaluation. During hospital stay her potassium levels in whole blood, serum and plasma reportedly differed significantly. An abnormal WBC count beyond assay range was reported and during subsequent investigations this lead to a peripheral smear being advised and diagnosis revealed chronic lymphoblastic leukaemia with blast crisis and 86% blast cells. In patients with leukocytosis and thrombocytosis, pseudohyperkalemia may exist in the absence of electrocardiogram changes or other clinical manifestations of true hyperkalemia thus leading to reevaluation of potassium values in serum, plasma and whole blood to arrive at the true picture.  相似文献

Objectives: This study evaluates malaria vaccine research carried out in different parts of the world during 1972–2004 using different bibliometric indicators. Method: Data have been downloaded from PubMed for the period 1972–2004 using the keywords (malaria* or plasmodium or falciparum) and (vaccine*) in the title and abstract fields. The study examined the pattern of growth of the output, its geographical distribution, profile of different countries in different subfields and pattern of citations using GOOGLE Scholar. Results: Malaria vaccine research output is gradually increasing. The USA, followed by the UK and Australia contributed the highest number of papers. Publication activity has decreased in Switzerland and Sweden, but has increased in Brazil and China. The majority of the countries have focused on the development of asexual blood stage malaria. Citations per paper and incidence of high‐quality papers for the USA, the UK, Papua New Guinea and Denmark are more than the average. The majority of the prolific institutions are located in the USA, the UK, France and Australia. Conclusion: The last two decades have witnessed considerable growth in research output in this field, while a successful malaria vaccine still remains elusive. Interestingly, the countries like the USA, the UK and Australia that lead in the quantity, quality and citation of this output are often not those directly affected by malaria.  相似文献

Objective

Psychological maltreatment (PM) is a widespread form of child maltreatment both in high-risk and maltreating families as well as in the general population of parents, yet there are no intervention programs that target it directly. The current study was designed as the first step in a larger program of research concerning educating parents about PM. In this study we evaluated the content of universal parenting programs to assess whether they include content on PM. Three questions were addressed: (1) Which types, if any, of PM were included in the content of these programs? (2) Which programs, if any, have content about each of the types of PM? (3) What are the implications for the development of PM curricula for parents?

Method

Ten evidence-based, manualized, universal parenting programs identified from SAMHSA or a comparable model program registry were rated on how well their content covered 18 types of psychological maltreatment (PM), as defined by the American Professional Society on the Abuse of Children, APSAC ( [Bingelli et al., 2001] and [0160] ). Each type of PM was coded along several dimensions which resulted in two summary scores: (1) Does the program contain content designed to teach parents what not to do in regards to the 18 psychologically maltreating behaviors and (2) Does the program contain content designed to teach parents what to do instead?

Results

Content related to most PM types were not included in the curricula, especially regarding “what not to do” and not one program was rated as having content related to teaching all 18 types of PM.

Conclusions

Existing parenting programs do not currently cover content for teaching community parents about psychological maltreatment.  相似文献
