Cutaneous leishmaniasis: Clinical report of two cases and review of the recent literature

With 1–1.5 million cases reported every year cutaneous leishmaniasis represents an increasing health problem. The course of cutaneous leishmaniasis varies from a single self‐healing ulcer to a persistent ulcer or progressive mucosal disease with nasopharyngeal destruction. An enormous array of topical and systemic treatment modalities has been endorsed. The response to treatment depends on the species of parasite as well as the host's immunological and genetic status. Species‐specific treatment guidelines based on evidence from controlled studies are highly desirable. We present two cases of cutaneous leishmaniasis, one in a child and one during pregnancy, reviewing various diagnostic and therapeutic measures with special attention to problems in young and pregnant patients.     

Adipose tissue and liver lipid metabolism in obese children: role of the body mass index and the presence of acanthosis nigricans.

AIMS: The aims of our study were to determine if insulin resistance is associated with increased plasma levels of non-esterified fatty acids (NEFA), glycerol, 3-hydroxybutyrate and triglycerides in obese children. We also studied whether the presence of acanthosis nigricans (AN) led to further alterations in the above parameters. METHODS: A total of 101 children were studied on their first visit to the paediatric endocrine clinic. Seventy-four were obese, 30 of them with AN. The remaining 27 were non-obese healthy children (control group). NEFAs, glycerol, triglycerides, 3-hydroxybutyrate, insulin, leptin, adiponectin and glucose were determined in blood samples obtained after overnight fasting. The insulin resistance index (IRI) was calculated following the homeostasis model assessment (HOMA). Data from the three groups were compared using appropriate statistical tests. RESULTS: No differences in age, sex ratio and pubertal stage were observed among the three groups. The group of children with the highest body mass index (BMI) showed higher plasma levels of insulin and leptin, higher IRI and lower plasma levels of adiponectin. As insulin and IRI increased, NEFA and 3-hydroxybutyrate decreased and triglycerides increased. When obese children were categorized by BMI, the presence of AN further exacerbated these differences. CONCLUSIONS: In obese children, insulin resistance is associated with plasma lipid alterations suggestive of both decreased adipose tissue lipolysis and hepatic beta-oxidation and increased hepatic synthesis of triglycerides. Such a metabolic condition may facilitate fat storage and hinder weight loss.     

CD34+细胞自身移植治疗儿童难治型系统性红斑狼疮

目的探讨治疗儿童难治型系统性红斑狼疮(SLE)积极、有效的方法.方法对2例病程分别为5年和7年,狼疮肾Ⅲ级和Ⅳ级,主要表现为持续性血小板减少、蛋白尿和浆膜炎的患儿进行CD34+细胞分选的自身干细胞移植.首先经惠尔血动员、CS-3000血细胞分离机获取单个核细胞,通过CliniMACS CD34+细胞分选仪分别得到了1.7×106/kg及1.0×106/kg CD34+细胞,采集物中分别尚存2×105/kg和1×104/kg的CD3+细胞.用CTX 50 mg/kg·d×4 d+ATG(Fresennius S 5 mg/kg·d×3 d)预处理.结果两患者分别于+9 d和+7 d获粒细胞重建,自+15 d起血小板维持于正常水平.现已分别随访13月和6月,原发病症状完全消失,自身免疫相关抗体全部转阴,但细胞免疫功能仍未恢复,CD4细胞仍处于低水平.结论CD34+细胞分选的自身干细胞移植治疗儿童难治型红斑狼疮近期疗效满意.     

慢性鼻窦炎患儿家长疾病知识认知度调查

目的了解鼻窦炎患儿家长对儿童鼻窦炎相关知识的认知情况,为进一步加强卫生宣教、预防儿童鼻窦炎提供理论依据。方法对65名鼻窦炎患儿家长进行关于儿童鼻窦炎发病因素、临床表现、并发症以及对儿童生长发育影响等问题的问卷调查。结果调查显示95.4%的家长对儿童鼻窦炎知识缺乏了解,且知识获得途径单一。结论应通过各种途径加强儿童鼻窦炎知识的宣教,积极预防儿童鼻窦炎。     

A Decision Rule for Predicting Bacterial Meningitis in Children with Cerebrospinal Fluid Pleocytosis When Gram Stain Is Negative or Unavailable

Objectives:  Among children with cerebrospinal fluid (CSF) pleocytosis, the task of separating aseptic from bacterial meningitis is hampered when the CSF Gram stain result is unavailable, delayed, or negative. In this study, the authors derive and validate a clinical decision rule for use in this setting.
Methods:  This was a review of peripheral blood and CSF test results from 78 children (<19 years) presenting to Children's Hospital Columbus from 1998 to 2002. For those with a CSF leukocyte count of >7/μL, a rule was created for separating bacterial from viral meningitis that was based on routine laboratory tests, but excluded Gram stain. The rule was validated in 158 subjects seen at the same site (Columbus, 2002–2004) and in 871 subjects selected from a separate site (Boston, 1993–1999).
Results:  One point each (maximum, 6 points) was assigned for leukocytes >597/μL, neutrophils >74%, glucose <38 mg/dL, and protein >97 mg/dL in CSF and for leukocytes >17,000/mL and bands to neutrophils >11% in peripheral blood. Areas under receiver-operator-characteristic curves (AROCs) for the resultant score were 0.98 for the derivation set and 0.90 and 0.97, respectively, for validation sets from Columbus and Boston. Sensitivity and specificity pairs for the Boston data set were 100 and 44%, respectively, at a score of 0 and 97 and 81% at a score of 1. Likelihood ratios (LRs) increased from 0 at a score of 0 to 40 at a score of ≥4.
Conclusions:  Among children with CSF pleocytosis, a prediction score based on common tests of CSF and peripheral blood and intended for children with unavailable, negative, or delayed CSF Gram stain results has value for diagnosing bacterial meningitis.     

Learning to Observe Relationships and Coping

Milieu relationships provide the critical background presence to staff's attempts to motivate, regulate, and teach patients how to cope with stress. Forging a connection with hospitalized children and adolescents demands attention to how they respond to adults and engage with staff around milieu expectations. Assessment guides that deal with these issues are presented. Important aspects of children's relatedness are presented in the context of their working models of adults and the influence of these representations on their response to staff. Coping skills are explained with particular emphasis on behavioral coping strategies. Tied to the assessment process are interventions that emphasize staff's role in helping patients manage strong affects and avoid the use of nonproductive behavior regulation strategies.
