Cerebral Palsy

INTRODUCTION: Cang Er Zi Wan (CEZW) is a herbal medication derived from Xanthium sibiricum that is used to treat allergies and upper respiratory problems. Its toxicity has been described in grazing animals, in experimental studies, and in human overdoses. We describe a case of muscular spasm that was associated with the therapeutic use of CEZW. CASE REPORT: A 17-year-old female was prescribed CEZW for chronic allergies. Shortly after her second dose of 10 pills BID, she developed intermittent muscular spasms. She was seen in an Emergency Department and had normal vital signs and no significant laboratory abnormalities. Her physical exam was significant only for intermittent spasm of the muscles of the face, neck, and upper extremities. No tremor, fasciculation, dystonia, akisthisia, chorea, bradykinesia, or clonus was noted. She discontinued the CEZW and the symptoms slowly decreased over 4 days. Testing of the product did not detect any other medications or drugs. DISCUSSION: CEZW is a herbal medication that contains X. sibiricum. X. sibiricum is a widespread weed that has caused muscular spasm, seizures, and death in animals that graze on it as well as animals experimentally exposed to it. Eleven cases of accidental human ingestion of Xanthium leading to spasm, somnolence, hypoglycemia, renal, and liver toxicity have been described. We describe a unique case of isolated muscular spasms because of the therapeutic use of a CEZW product.

OBJECTIVE: Antagonism at the serotonin receptor 2A by the atypical antipsychotics clozapine and olanzapine has been suggested to be linked to these drugs' adverse effects on glucose-insulin homeostasis. Therefore, the aim of this study was to evaluate the impact of haplotypes based on the main functionally characterized polymorphisms of the serotonin receptor 2A (HTR2A) gene on parameters related to the glucose metabolism in clozapine- and olanzapine-treated patients. METHODS: Forty-nine patients, with schizophrenia or schizoaffective disorder and treated with clozapine (n = 22) or olanzapine (n = 27), were evaluated for fasting levels of C-peptide, insulin and blood glucose, homeostasis model assessment index for insulin resistance (HOMA-IR) and body mass index (BMI), and genotyped for the -1438A/G, -783A/G, 102T/C, and His452Tyr polymorphisms of the HTR2A gene. RESULTS: About 50% of the patients had elevated levels of C-peptide (>0.68 nmol/L) and insulin (>/=79 pmol/L). However, patients carrying the haplotype [-1438A, -783A, 102T, 452Tyr] had significantly lower C-peptide levels compared with patients not carrying this haplotype (p = 0.039), despite no differences in blood glucose, HOMA-IR or BMI between the patient groups. CONCLUSION: Our results indicate that patients with the HTR2A haplotype [-1438A, -783A, 102T, 452Tyr] are less likely to develop metabolic abnormalities like C-peptide and insulin elevations during clozapine and olanzapine treatment.

BACKGROUND: Because of persistent stunning, post-treatment functional abnormalities could identify the initial risk area. The study aims to detect myocardial salvage using post-revascularization gated SPECT in acute myocardial infarction (AMI) treated by reperfusion therapy. METHODS: In 36 AMI patients, we performed a first gated SPECT injecting (99m)Tc-sestamibi before primary percutaneous coronary intervention (PCI), and a second 5 days later. The salvage index defined by the two perfusion images was compared with the value obtained by subtracting in the second gated SPECT the extent of perfusion defect from the extent of wall thickening abnormalities. RESULTS: The wall thickening salvage index correlated with the reference perfusion salvage index (Spearman's rho = .92, P < .0001), with a 95% limit of agreement = +/-.25. The agreement between the classifications in salvage index tertiles of the reference and of the wall thickening salvage index was good (kappa = .75). All patients with optimal PCI result and 18/24 of those with intermediate or poor outcome were correctly classified. CONCLUSIONS: Comparing function and perfusion in a single post-PCI (99m)Tc-sestamibi gated SPECT it is possible to estimate myocardial salvage. This could have useful implications in studies comparing different treatment strategies for AMI.

BACKGROUND: In line with current guideline recommendations, patients at high cardiovascular risk are usually treated with statins for secondary as well as for primary prevention. While many studies investigated treatment goal achievement with regards to low-density lipoprotein (LDL-C) and total cholesterol (TC) there is paucity of data regarding high density lipoprotein (HDL-C), and/or triglycerides (TG). SETTING: Prospective, cross-sectional study (Dyslipidemia International Survey, DYSIS) with data provided by 748 office-based physicians throughout Germany. METHODS: Consecutive patients were eligible for participation, if they were at least 45 years old, currently treated with a statin and had had a documented lipid profile (at least 1 parameter) within the last 6 months. Besides descriptive analyses, logistic regression was performed with backward selection to assess predictors for lipid abnormalities (non-attainment of goals for TC, LDL-C, low HDL-C or elevated TG) classified according to current European Society of Cardiology guidelines. RESULTS: The 4,282 documented patients (98.6% Caucasian, 56.4% male; 86.6% at high cardiovascular risk) were predominantly treated with simvastatin (83.9%), pravastatin (7.7%) or atorvastatin (3.9%), usually with doses equivalent to simvastatin 20-40 mg daily. Non-statins were used in at most 12% of patients. No lipid abnormalities were found in 21.0% of patients, one abnormality in 38.5%, two in 31.9%, and all three in 8.5%. LDL-C goals were not attained in 58.1%, elevated TC was found in 66.6%, low HDL-C in 22.7%, and elevated TG in 47.3%. In the multivariate logistic regression model, non-attainment of LDL-C levels was predicted by hypertension (odds ratio, OR 1.4), current smoking (OR 1.3), sedentary lifestyle (OR 1.3), and female gender (OR 1.3). On the other hand, a reduced risk for missing LDL-C targets was noted in the presence of ischemic heart disease (OR 0.6), diabetes (0.5), higher statin doses, ezetimibe treatment, or specialist care, respectively. CONCLUSION: A substantial proportion of statin-treated patients not only missed targets for LDL-C, but also did not attain the normal levels for HDL-C and/or TG. There is a large disconnect between high prevalence of HDL and/or TG disorders, with or without elevated LDL-C, and utilization of therapies targeting these lipids. Particularly in high-risk patients, additional efforts should be made to improve their lipid profile.

Hay-Wells syndrome is a rare form of ectodermal dysplasia initially described by Hay and Wells in 1976. It is an autosomal dominant disorder with varying forms of expression featuring congenital abnormalities of the skin, hair, teeth, nails and sweat glands. The present report describes the case of a 17-yearold white boy, the son of nonconsanguineous parents, who presented ankyloblepharon filiforme adnatum, ectodermal dysplasia and a cleft palate at birth, which are considered cardinal signs of this syndrome by most authors. We also highlight the importance of implementing multidisciplinary follow-up of these patients.

Research about the skin barrier and its properties has increased significantly since the 60s, with studies that indicated its resistance when isolated, as well as its particularities in relation to skin permeability. At the same time, description of Odland bodies helped to understand how stratum corneum stability is maintained. The âbrick and mortarâ model is the most accepted so far. In this analogy, the corneocytes are the bricks and the intercellular lipids are the mortar. Currently, there is concrete evidence that the stratum corneum is an active metabolic structure that holds adaptive functions, interacting dynamically with the underlying epidermal layers. The skin barrier also plays a role in the inflammatory response through melanocyte activation, angiogenesis, and fibroplasia. The intensity of this response will essentially depend on the severity of the injury. Skin barrier abnormalities in atopic dermatitis are clinically observed by the presence of dry skin, a common and significant symptom which constitutes a diagnostic and monitoring parameter. The stratum corneum hydration level and transepidermal water loss are associated with the level of damage to the barrier, representing biophysical parameters. These parameters help doctors monitor patients in a less invasive and more sensitive manner.

BACKGROUND: Chronic Fatigue Syndrome (CFS) studies from our laboratory and others described decreased natural killer cell cytotoxicity (NKCC) and elevated proportion of lymphocytes expressing the activation marker, dipeptidyl peptidase IV (DPPIV) also known as CD26. However, neither these assays nor other laboratory tests are widely accepted for the diagnosis or prognosis of CFS. This study sought to determine if NKCC or DPPIV/CD26 have diagnostic accuracy for CFS. METHODS/RESULTS: Subjects included female and male CFS cases and healthy controls. NK cell function was measured with a bioassay, using K562 cells and (51)Cr release. Lymphocyte associated DPPIV/CD26 was assayed by qualitative and quantitative flow cytometry. Serum DPPIV/CD26 was measured by ELISA. Analysis by receiver operating characteristic (ROC) curve assessed biomarker potential. Cytotoxic function of NK cells for 176 CFS subjects was significantly lower than in the 230 controls. According to ROC analysis, NKCC was a good predictor of CFS status. There was no significant difference in NK cell counts between cases and controls. Percent CD2+ lymphocytes (T cells and NK cells) positive for DPPIV/C26 was elevated in CFS cases, but there was a decrease in the number of molecules (rMol) of DPPIV/C26 expressed on T cells and NK cells and a decrease in the soluble form of the enzyme in serum. Analyses by ROC curves indicated that all three measurements of DPPIV/CD26 demonstrated potential as biomarkers for CFS. None of the DPPIV/C26 assays were significantly correlated with NKCC. CONCLUSIONS: By ROC analysis, NKCC and three methods of measuring DPPIV/C26 examined in this study had potential as biomarkers for CFS. Of these, NKCC, %CD2+CD26+ lymphocytes and rMol CD26/CD2+ lymphocyte, required flow cytometry, fresh blood and access to a high complexity laboratory. Soluble DPPIV/C26 in serum is done with a standard ELISA assay, or with other soluble factors in a multiplex type of ELISA. Dipeptidyl peptidase IV on lymphocytes or in serum was not predictive of NKCC suggesting that these should be considered as non-redundant biomarkers. Abnormalities in DPPIV/CD26 and in NK cell function have particular relevance to the possible role of infection in the initiation and/or the persistence of CFS.

Maize silks, dried cut stigmata of maize female flowers, are a traditional medicinal plant. This study was conducted to investigate the antioxidant effect of maize silks ethanol extract (MSE) against oxidative damage in vivo. gamma-radiation was employed to induce oxidative stress in mice and the variation of malondialdehyde (MDA), glutathione/glutathione disulfide ratio (GSH/GSSG), blood cells, NF-E2-related factor 2 (Nrf2) and related antioxidant enzymes were examined. The results showed that radiation elevate levels of MDA, induce hematological abnormalities and decrease levels of GSH/GSSG and Nrf2 expression in liver and kidney. MSE administration significantly abolished elevation of MDA levels in liver, maintained hepatic GSH/GSSG ratio and ameliorated hematological abnormalities dose dependently. Moreover, MSE up-regulated the hepatic protein expression of Nrf2 dose dependently and the activities as well as protein expression of Nrf2-related antioxidant enzymes were also increased. However, the antioxidant ability of MSE seemed not to be as effective in kidney as in liver. These findings firstly proved the protective role of MSE against oxidative stress, which was in part via up-regulation of Nrf2 and seemed to be tissue specific.
