Patients were asked to answer a questionnaire to assess the impact of several sociodemographic factors.Results: A total of 397 patients agreed to take the questionnaire. Diabetic vitreous hemorrhage was the most common ocular complication and was found in 359 patients (90.4%. A total of 158 (39.8% patients knew that diabetes mellitus can be sight threatening, while 240 (60.2% were not aware until they developed sight threatening complication. A total of 179 patients (45.1% had early retirement because of visual loss related to diabetes mellitus. Multivariate logistic regression has shown that education, internist, contact with other patients, and media were respectively significant in predicting the awareness of patients about the sight-threatening effect of diabetic retinopathy.Conclusion: Patient education regarding diabetes and diabetic eye disease is essential for early detection and compliance with treatment. Illiteracy has a significant impact on development of sight-threatening diabetic complications. The internist is the first line of prophylaxis. Media has to participate more in patient education.Keywords: blindness, education, laser photocoagulation, macular edema, vitreous hemorrhage

    The clinical manifestations associated with H5N1 infection in humans range from asymptomatic infection to mild upper respiratory illness, severe pneumonia, and multiple organ failure. The ratio of symptomatic cases to asymptomatic cases is not known, because it is not possible to precisely define the number of asymptomatic cases. A total of 97 cases suffering from avian flu were suspected based on history taking, demographic data, clinical manifestations, laboratory and radiological investigations. The followings were done for all cases; complete blood picture (differential leucocytic count), coagulation profile, renal and liver function tests. H5N1 influenza virus was diagnosed thorough PCR technique. Changes in arterial blood gases and repeated chest X-rays were reported frequently. All patients were given specific antiviral therapy (oseltamivir). The study described the clinical picture and laboratory results of 81 confirmed avian influenza human cases in an Egyptian hospital (Abassia chest hospital), and reviewed the avian influenza current situation covering from March 2006 to June 2009 with very high pick in the first half of 2009. The significant apparent symptoms were fever as initial and main symptom (93.75%), followed by shortness of breathing (73%), cough (66.6%), muscle & joint pain (60%) and sore throat (40%).

    Full Text Available Context: Alopecia areata (AA is a common form of localized, non-scarring hair loss. The etiopathogenesis of the disease is still unclear, but the role of autoimmunity is strongly suggested. AA is commonly associated with various autoimmune disorders; the most frequent among them is autoimmune thyroid disorders. Aim: To determine whether AA is associated with thyroid autoimmunity or thyroid function abnormalities in Egyptian patients. Materials and Methods: Fifty subjects with AA (37 males and 13 females without clinical evidence of thyroid disorders were selected from Dermatology Outpatient Clinic, Menoufiya University Hospital, Menoufiya Governorate, Egypt, during the period from June 2009 to February 2010. They were divided into 3 groups according to severity of AA. Fifty age and sex-matched healthy volunteers (35 males and 15 females were selected as a control group. Every case and control were subjected to history taking, complete general and dermatological examination. Venous blood samples were taken from cases and controls after taking their consents for measurement of thyroid stimulating hormone (TSH, free T3, freeT4 and detection of Anti-thyroglobulin Antibody (Tg-Ab and Anti-thyroid Peroxidase Antibody (TPO-Ab. Results: Subclinical hypothyroidism was detected in 16% of cases. There were statistically significant differences between cases and controls regarding levels of TSH, free T3 and free T4. There were significant differences between cases and controls regarding the presence of Tg-Ab and TPO-Ab. Conclusions: Every patient with AA should be screened for thyroid functions and presence of thyroid autoantibodies even in absence of clinical manifestations suggestive of thyroid affection.

    Full Text Available Background: Hyperuricemia is commonly associated with hypertension. Also, it is well known to coincide with the metabolic syndrome but is still not recognized as a risk factor. So, we aimed to evaluate hyperuricemia among a sample of hypertensive Egyptians with normal renal function.Methods: this study was performed on 303 hypertensive patients aged 30-69 years. Patients were divided into 2 groups according to the level of uric acid: group 1 composed of 168 hypertensive hyperuricemic patient sand group2 composed of 135 hypertensive normouricemic patients. All patients were subjected to complete medical history and detailed clinical examination including body mass index (BMI, complete blood count (CBC, serum creatinine, BUN, FBS, cholesterol, triglycerides, uric acid, sodium, potassium, urinary uric acid, urinary creatinine, urinary uric acid to creatinine ratio and fractional excretion of uric acid(FEUA.Results: The overall prevalence of hyperuricemia was 55.4%. Uric acid correlated significantly with age (p0.05. Serum uric acid found to correlate significantly (p<0.001 with urinary uric acid, urinary creatinine and negatively with FEUA denoting early tubular defect of the kidney. Also, Urinary uric acid, urinary creatinine and urinary uric acid/creatinine ratio were higher in group 1than in group 2 (p values were<0.001, <0.001 and <0.05 respectively. FEUA was found to be significantly lower in group 1 than in group 2 (p<0.01. We found, also, that serum sodium level was significantly higher in the hyperuricemic group than in the normouricemic group (p<0.001 denoting the role of Na+ in the development of hypertension and defective renal excretion of uric acid.Conclusion: We conclude that the incidence hyperuricemia in our sample of Egyptian hypertensive patients was (55.4%. Impaired renal clearance of uric acid occurs before deterioration of GFR. Serum uric acid should be measured in all cases of hypertension together with BMI, total cholesterol

    The fear of using tramadol for pain control (tramadolophobia) by Egyptian patients with cancer is a frequent problem in our practice. This study was conducted to explore the prevalence of and the reasons behind tramadolophobia among Egyptian patients with cancer. A structured interview including open-ended and closed questions. The study included 178 adult patients with cancer from two cancer centers in Cairo and Sharkia, Egypt. The source of information about tramadol was a non-healthcare-related source in 168 (94 percent) patients, mainly the media (50 percent). The believed uses of tramadol were abuse related in 94 (53 percent) patients, stimulant (physical, sexual, and to boost alertness) in 59 (33 percent), and analgesic in 55 (31 percent). Twenty-six (15 percent) patients gave history of tramadol use, largely (69 percent) as a stimulant. In case tramadol was prescribed for pain control, 90 (51 percent) patients refused to take it, 59 (33 percent) patients agreed to take it with concern about addiction, and only 29 (16 percent) patients agreed without concerns. Among those who refused taking tramadol for pain, the mentioned reason of refusal was addiction-related fears in 57 percent. The stigmatization and misconceptions about tramadol may have resulted in tramadolophobia among the majority of Egyptian patients with cancer. This further complicates the barriers to cancer pain control in Egypt. Being the only available World Health Organization step-II analgesic in Egypt, interventions to overcome tramadolophobia should be taken.

    The aim of the study was to assess the serum levels of Syndecan-1 in a group of Egyptian juvenile systemic lupus erythematosus (JSLE) patients and to study any possible associations with disease activity, renal activity and organ damage. Serum level of Syndecan-1 was assessed in 60 Egyptian JSLE patients and 30 apparently healthy age and gender matched children using ELISA. SLE Disease Activity Index-2000 (SLEDAI-2K), renal SLEDAI-2K, renal activity score and the Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index were assessed for all patients. Serum SDC-1 levels were higher in patients with JSLE than in healthy controls (p<0.001) and were positively correlated with SLEDAI-2K (p<0.001), with renal SLEDAI score (p=0.008) and renal activity score (p=0.04). So, Syndecan-1 might be used as a marker for disease activity and renal activity in JSLE patients.

    AIM: To describe the socio-demographic features, eti ology, and risk factors for Budd-Chiari syndrome (BCS) in Egyptian patients.METHODS: Ninety-four Egyptian patients with con firmed primary Budd-Chiari syndrome were presented to the Budd-Chiari Study Group (BCSG) and admitted to the Tropical Medicine Department of Ain Shams University Hospital (Cairo, Egypt). Complete clinical evaluation and laboratory investigations, including a thrombophilia workup and full radiological assessment, were per formed to determine underlying disease etiologies.RESULTS: BCS was chronic in 79.8% of patients, acute or subacute in 19.1%, and fulminant in 1.1%. Factor V Leiden mutation (FVLM) was the most com mon etiological cause of disease (53.1%), followed by mutation of the gene encoding methylene tetra hydrofolate reductase (MTHFR) (51.6%). Current or recent hormonal treatment was documented in 15.5% of females, and BCS associated with pregnancy was present in 17.2% of females. Etiology could not be de termined in 8.5% of patients. Males had significantly higher rates of MTHFR gene mutation and Behget' s disease, and females had significantly higher rates of secondary antiphospholipid antibody syndrome. A highly significant positive relationship was evident between the presence of Behget's disease and inferior vena caval occlusion, either alone or combined with occlusion of the hepatic veins (P < 0.0001).CONCLUSION: FVLM is the most common disease etiology and MTHFR the second most common in Egyptian BCS patients. BCS etiology tends to vary with geographic region.

    Protein Z has been reported to exert an important role in inhibiting coagulation. Polymorphisms in the protein Z gene (PROZ) may affect protein Z levels and thus play a role in thrombosis. This study aimed to investigate the prevalence and clinical significance of protein Z gene G79A polymorphism in Egyptian patients with systemic lupus erythematosus (SLE). We studied the distribution of the protein Z gene (rs17882561) (G79A) single-nucleotide polymorphism by PCR-restriction fragment length polymorphism in 100 Egyptian patients with SLE and 100 age, sex, and ethnically matched controls. There was no statistically significant difference in the distribution of the genotypes between SLE patients and the control group in our study (P = 0.103). But a statistically significant difference in the frequency of the alleles between SLE patients and controls was observed (P = 0.024). Also a significant association was detected between protein Z genotypes (and also A allele) and thrombosis, which is one of the manifestations of SLE (P = 0.004 and P = 0.001, respectively). Moreover, we observed a significant association between the protein Z AA and GA genotypes (and also A allele) and the presence of anticardiolipin antibodies (P = 0.016 and P = 0.004, respectively). The minor A allele of the G79A polymorphism in the protein Z gene might contribute to the genetic susceptibility of SLE in Egyptian patients. Also, an influence for this polymorphism on some of the disease manifestations has been elucidated, so protein Z G79A AG/AA may be a risk factor for thrombosis.

    Background. Occult hepatitis C virus infection (OCI) was identified as a new form of Hepatitis C virus (HCV), characterized by undetectable HCV antibodies and HCV RNA in serum, while HCV RNA is detectable in liver and peripheral blood cells only. Aim. The aim of this study was to investigate the occurrence of OCI in Egyptian patients with lymphoproliferative disorders (LPDs) and to compare its prevalence with that of HCV in those patients. Subjects and Methods. The current study included 100 subjects, 50 of them were newly diagnosed cases having different lymphoproliferative disorders (patients group), and 50 were apparently healthy volunteers (controls group). HCV antibodies were detected by ELISA, HCV RNA was detected in serum and peripheral blood mononuclear cells (PBMCs) by reverse transcription polymerase chain reaction(RT-PCR), and HCV genotype was detected by INNO-LiPA. Results. OCI was detected in 20% of patients group, compared to only 4% OCI in controls group. HCV was detected in 26% of patients group with a slightly higher prevalence. There was a male predominance in both HCV and OCI. All HCV positive patients were genotype 4. Conclusion. Our data revealed occurrence of occult HCV infection in Egyptian LPD patients at a prevalence of 20% compared to 26% of HCV.

    Long waiting list times in liver transplant programs in Saudi Arabia and unavailability of deceased donor transplantation in Egypt have led several patients to seek transplantation in China. All patients who received transplants in China and followed in three centers from January 2003-January 2007 were included. All patients' charts were reviewed. Mortality and morbidity were compared to those transplanted in King Faisal Specialist Hospital & Research Centre (KFSH&RC) during the same period. Seventy-four adult patients were included (46 Saudi nationals; 28 Egyptians). One-year and 3-year cumulative patient survival rates were 83% and 62%, respectively compared to 92% and 84% in KFSH&RC. One-year and 3-year cumulative graft survival rates were 81% and 59%, respectively compared to 90% and 84% in KFSH&RC. Compared to KFSH&RC, the incidence of complications was significantly higher especially biliary complications, sepsis, metastasis and acquired HBV infection posttransplant. Requirements of postoperative interventions and hospital admissions were also significantly greater. Our data show high mortality and morbidity rates in Saudi and Egyptian patients receiving transplants in China. This could be related to more liberal selection criteria, use of donation after cardiac death (DCD) donors or possibly more limited posttransplant care.

    Background. Hepatitis C is a global major health problem with extremely variable extrahepatic manifestations. Mixed cryoglobulinaemia (MC) shows a striking association with hepatitis C virus (HCV) infection, and it is sometimes asymptomatic. The skin is a frequently involved target organ in MC. Objective. To investigate the prevalence of cryoglobulinaemia in a sample of Egyptian patients with cutaneous manifestations of chronic HCV infection and to correlate its presence with clinical criteria and liver function tests. Methods. One hundred and eighteen patients with skin manifestations of chronic compensated hepatitis C were included. Venous blood was tested for liver function tests and serum cryoglobulins. Results. Twelve patients (10.169%) were positive for serum cryoglobulins (2 with pruritus, 4 with vasculitic lesions, 3 with livedo reticularis, one with oral lichen, one with chronic urticaria, and another with Schamberg's disease). Vasculitic lesions and livedo reticularis of the legs showed higher prevalence in cryoglobulin-positive than in cryoglobulin-negative patients. Presence of serum cryoglobulins did not relate to patients' demographic or laboratory findings. Conclusions. Fortunately, MC is not markedly prevalent among Egyptians with cutaneous lesions of chronic hepatitis C, and cryopositivity was commonly, but not exclusively, detected with cutaneous vasculitis and livedo reticularis. Laboratory testing for cryoglobulins in every HCV patient is advisable for earlier MC detection and management.

    Chronic hepatitis C virus (HCV) infection combined with occult hepatitis B virus (HBV) infection has been associated with increased risk of hepatitis, cirrhosis and hepatocellular carcinoma. This study aimed to determine the prevalence of occult HBV infection among Egyptian chronic HCV patients, the genotype and occurrence of surface gene mutations of HBV and the impact of co-infection on early response to treatment. The study enrolled 162 chronic HCV patients from Ismailia Fever Hospital, Egypt, who were HBV surface antigen-negative. All patients were given clinical assessment and biochemical, histological and virological examinations. HBV-DNA was detectable in sera from 3 patients out of the 40 patients who were positive for hepatitis B core antibody. These 3 patients were responsive to combination therapy at treatment week 12; only 1 of them had discontinued therapy by week 24. HBV genotype D was the only detectable genotype in those patients, with absence of "a" determinant mutations among those isolates.

  1. Analysis of oxidative stress status, catalase and catechol-O-methyltransferase polymorphisms in Egyptian vitiligo patients.

    Full Text Available Vitiligo is the most common depigmentation disorder of the skin. Oxidative stress is implicated as one of the probable events involved in vitiligo pathogenesis possibly contributing to melanocyte destruction. Evidence indicates that certain genes including those involved in oxidative stress and melanin synthesis are crucial for development of vitiligo. This study evaluates the oxidative stress status, the role of catalase (CAT and catechol-O-Methyltransferase (COMT gene polymorphisms in the etiology of generalized vitiligo in Egyptians. Total antioxidant capacity (TAC and malondialdehyde (MDA levels as well as CAT exon 9 T/C and COMT 158 G/A polymorphisms were determined in 89 patients and 90 age and sex-matched controls. Our results showed significantly lower TAC along with higher MDA levels in vitiligo patients compared with controls. Meanwhile, genotype and allele distributions of CAT and COMT polymorphisms in cases were not significantly different from those of controls. Moreover, we found no association between both polymorphisms and vitiligo susceptibility. In conclusion, the enhanced oxidative stress with the lack of association between CAT and COMT polymorphisms and susceptibility to vitiligo in our patients suggest that mutations in other genes related to the oxidative pathway might contribute to the etiology of generalized vitiligo in Egyptian population.

    Systemic lupus erythematosus (SLE) is a complex autoimmune disease. Cytokine gene polymorphisms play an important role in SLE. Thus, this study aimed to investigate the associations between interleukin 6 (IL-6) and interleukin 10 (IL-10) promoter single-nucleotide polymorphisms (SNPs) and their susceptibility to SLE and the implications for plasma levels. We genotyped IL-6-174G/C (rs1800795) using mutagenically separated polymerase chain reaction (MS-PCR) and IL-10-1082G/A (rs1800896) and -819C/T (rs1800871) using sequence specific primer polymerase chain reaction (SSP-PCR) in 100 Egyptian patients and 119 controls. The plasma levels of IL-6 and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). There was significant increase in the frequency of IL-6 (-174) GG genotype (P IL-10 (-1082G/A) GG (P IL-10 (P IL-10 gene polymorphisms in SLE patients. In conclusion, our preliminary study indicated that both GG genotype and G allele of IL-6 (-174G/C) could be considered as risk factors for SLE. In addition, the polymorphisms at IL-10 (-1082 G/G and AA) may play a role in SLE susceptibility in Egyptian patients. Larger prospective studies are needed to confirm our findings.

    Full Text Available Abstract Background Occult HBV infection accelerates the progression of liver fibrosis, cirrhosis, and finally leading to hepatocellular carcinoma (HCC. This study analyzed the occult HBV-genotypes in HCC patients. Methods To achieve our objective, matched serum and tissue samples were collected from 40 HCC patients. Three sets of primers were used for the HBV-DNA detection by nested-PCR, which cover the HBV-genome; Core, Surface and X genes. Genotyping system based on PCR using type-specific primers was applied on HBV-DNA positive samples. Results Intrahepatic occult HBV-DNA was detected in 62.5%, whereas; Serum occult HBV-DNA were detected in only 22.5% of HCC patients. In patients' positive for both anti-HBs and anti-HBc, 10% had occult HBV in serum. In serologically negative HCV patients, 63% had intrahepatic HBV-DNA, and 21% had HBV-DNA in serum samples. HBV-genotype D (32% and B (24% attributed predominantly to intrahepatic HBV infections in HCC patients, whereas HBV-genotype A (4% and C (8% infections were the least observed. Conclusion This is the first study to show the genotypes of occult HBV infection in HCC Patients. We suggest that B or D may influence the outcome of HBV infection which may lead to the development of HCC.

    Full Text Available Introduction: Chronic hepatitis C virus (HCV infection is a leading cause of end-stage liver disease worldwide. It has been shown that Helicobacter pylori (H. pylori plays an important role in chronic gastritis, peptic ulcer disease and gastric malignancies, and its eradication has been advocated. The association between H. pylori infection and liver cirrhosis in patients with hepatitis C virus has been documented in different parts of the world; nevertheless, no conclusive data is available in Egypt. Materials and Methods: In the present study, the status of H. pylori infection was sought in 90 patients with chronic HCV infection and in 66 HCV-free healthy controls. Results: The study showed that the H. pylori positivity was increased significantly (P = 0.03 in the HCV-infected patients when compared to that in healthy controls, where H. pylori infection was found in 50 (55.6% out of 90 of the HCV-infected patients versus 26 (39.4% out of 66 of the healthy controls. In HCV-infected patients, the prevalence of H. pylori infection was increased significantly (P = 0.04 from chronic active hepatitis to cirrhosis. H. pylori infection was present in 6/18 (33.3%, 10/21 (47.6%, 16/27 (59.3%, 18/24 (75.0% patients with chronic active hepatitis, Child-Pugh score A, Child-Pugh score B and Child-Pugh score C, respectively. More importantly, the prevalence of H. pylori infection in HCV-infected patients was increased very significantly (P = 0.003 with increasing Meld (model for end-stage liver disease score. The prevalence of H. pylori was documented in 9/28 (32.1% patients with Meld score ≤10 and in 41/62 (66.1% patients with Meld score> 10. Conclusion: It may be stated that our results collectively reflect a remarkable increase in H. pylori prevalence with advancing hepatic lesions, and the eradication treatment may prove beneficial in those patients with chronic hepatitis C.

    Occult hepatitis C virus (HCV) infection (OCI) was reported in an apparently disease-free state in the absence of liver disease, anti-HCV and HCV-RNA in the serum. The existing data examining the clinical significance of OCI and its potential as a source of HCV infection among hemodialysis patients are very limited. We examined the presence of OCI among patients on maintenance hemodialysis at Minia Governorate, Egypt; an HCV endemic country. A total of 81 subjects with negative markers for HCV were enrolled. HCV-RNA was tested in PBMCs by real-time PCR. For the 81 subjects, the average dialysis duration was 32.7 ± 21.7 months and the average ALT level (±SD) was 26 ± 12 U/L while that of AST was 29 ± 16 U/L. Out of the 81 subjects, three (3.7%) were HCV-RNA positive in PBMCs in the absence of serum anti-HCV and HCV-RNA indicating OCI. The viral load of the OCI subjects ranged from 172 to 4150 IU/ml. History of liver disease was positive in one of the three positive patients. These results highlight the potential risk of HCV transmission from patients within hemodialysis units in Egypt. J. Med.

    Objective The aim of this study was to assess the potential risk of gadobutrol-enhanced magnetic resonance imaging (MRI) in patients with moderate to severe renal impairment for the development of nephrogenic systemic fibrosis (NSF). Materials and Methods We performed a prospective, international, multicenter, open-label study in 55 centers. Patients with moderate to severe renal impairment scheduled for any gadobutrol-enhanced MRI were included. All patients received a single intravenous bolus injection of gadobutrol at a dose of 0.1 mmol/kg body weight. The primary target variable was the number of patients who develop NSF within a 2-year follow-up period. Results A total of 908 patients were enrolled, including 586 with moderate and 284 with severe renal impairment who are at highest risk for developing NSF. The mean time since renal disease diagnosis was 1.83 and 5.49 years in the moderate and severe renal impairment cohort, respectively. Overall, 184 patients (20.3%) underwent further contrast-enhanced MRI with other gadolinium-based contrast agents within the 2-year follow-up. No patient developed symptoms conclusive of NSF. Conclusions No safety concerns with gadobutrol in patients with moderate to severe renal impairment were identified. There were no NSF cases. PMID:27529464

    There are scanty data on the prevalence of vitamin D deficiency and its relation to disease activity among patients with juvenile-onset systemic lupus erythematosus (JoSLE) in the Middle East and North Africa, an area known to be endemic for vitamin D deficiency and insufficiency. The aim of this study was, therefore, to study vitamin D status and its relation to disease activity and parameters in Egyptian patients with JoSLE. Serum levels of 25(OH) D3 in 70 JoSLE patients were compared to 40 age-, sex-, and body mass index-matched healthy controls. The 25(OH) D3 was determined by enzyme-linked immunosorbent assay. Information regarding the medical history, clinical symptoms, and signs was registered at the time of serum sampling. Disease activity of SLE was evaluated according to the SLEDAI score. The mean level of serum 25(OH) D3 was 12 ± 3.7 in JoSLE patients compared to 21 ± 3.5 ng/mL in normal controls (p 30 ng/mL. There was no significant correlation between serum levels of 25(OH) D3 and the demographic data, medication used, and some laboratory data of patients with JoSLE. Disease activity score in our patients was insignificantly correlated with serum levels of 25(OH) D3. In spite of vitamin D supplementation in Egyptian JoSLE patients and the presence of vitamin D insufficiency in the control group, there are still significantly lower levels of vitamin D in JoSLE compared to normal controls.

    The CAG repeat and its association with infertility has been debatable. Therefore, this study was planned to assess the distribution of CAG repeat expansion in Egyptian patients and to investigate its association with male infertility. Forty-five infertile men were eligible for the study in addition to 20 aged-matched fertile males as control. Semen analysis, scrotal sonography, assay of serum testosterone, follicle-stimulating hormone (FSH) and luteinising hormone (LH), and determination of the CAG repeat number within exon 1 of the androgen receptor (AR) gene were carried out. Statistically significant difference was found between infertile and control groups regarding sperm count, sperm motility, serum FSH level and CAG repeats (P CAG repeats (P = 1.0) was found between oligozoospermic and asthenospermic groups; negative correlation was found between CAG repeat length and sperm count, and a positive correlation was found between CAG repeat length and serum FSH (P CAG repeat may be associated with lower AR function with derangement of sperm production, and this may contribute to male infertility in Egyptian men.

    Individualization of carbamazepine (CBZ) dosage regimen in patients with epilepsy based on based on therapeutic drug monitoring (TDM) followed by estimation of pharmacokinetic (PK) parameters can help in better control of epilepsy. Our objective was to establish a population (POP) PK model of CBZ for Egyptian adult and pediatric patients with epilepsy. Single steady-state (SS) trough plasma concentrations of CBZ were available for 302 patients with epilepsy (55·6% men and 44·4% women) who were categorized as children (n = 118) and adults (n = 184) with mean age (years) ± SD of 10·6 ± 4·8 and 29·4 ± 9·9, respectively. Carbamazepine was given as an oral suspension (n = 19) or controlled release tablet (n = 283) with average dose of 15·0 ± 7·8 mg/kg per day. A one-compartment model with first-order absorption and elimination for SS conditions (ADVAN2, SS2, TRANS2) was applied using NONMEM 6.2. Separate absorption rate constants were modelled for the two formulations. The mean POP CL, its intersubject variability (ISV), as well as residual error of CBZ concentration were estimated. The POP estimate for CL was 3·5 L/h with coefficient of variation value of 2·6%, which was consistent with literature data. The ISV on CL was 44·5%. The POP PK model was validated by bootstrap re-sampling, and the individual estimates were within the 95% CI of the bootstrap results. Different covariates that might affect CBZ CL have been evaluated but the limited number of samples per individual prevented precise covariate analysis. The POP PK model we have developed for CBZ shows good predictive performance in Egyptian adult and pediatric patients with epilepsy. Another PK study to better define the effect of different covariates would improve on the model for dosage individualization. © 2011 Blackwell Publishing Ltd.

    Full Text Available Abstract Background Chronic HCV infection combined with occult hepatitis B infection has been associated with liver enzymes flare, advanced hepatic fibrosis and cirrhosis, poor response to standard interferon-α, and increased risk of HCC. This study aimed to elucidate the prevalence of occult hepatitis B infection in Egyptian chronic HCV patients, and to clarify its role in non-response of those patients to pegylated interferon/ribavirin therapy. This study enrolled 155 consecutive chronic HCV patients under pegylated interferon/ribavirin therapy. All patients were exposed to clinical assessment, biochemical, histological and virological examinations. HBV parameters (HBV DNA, anti-HBc, anti-HBs and patients' response status to the combination therapy were determined. Results In this study, occult hepatitis B infection occurs in 3.9% of Egyptian chronic HCV patients; tends to affect younger age patients, associated with higher base line HCV viral load, less hepatic fibrosis than monoinfected patients. This occult hepatitis B infection is not a statistically significant cause of non-response to pegylated interferon/ribavirin therapy. Anti-HBs was not associated with any biochemical, histological or virological abnormalities in those patients, contrary to low response rate to therapy and higher HCV viral load that was observed with anti-HBc. Conclusions Detection of HBV DNA in HBsAg negative chronic HCV patients plays a non significant role in non-response of Egyptian patients to pegylated interferon/ribavirin therapy.

    Chronic hepatitis C virus (HCV) infection may have extremely variable clinical consequences and is more than just a liver disease; it has been associated with numerous extra-hepatic manifestations (EHM). According to various international studies Mixed Cryoglobulinemia (MC) was found to be the most common EHM, however its local prevalence in Egyptian HCV patients was not clearly studied. The aim of our study was to investigate the frequency of cryoglobulinaemia in sera of chronic HCV patients...

    Increasing numbers of Egyptians with end-stage liver disease seek liver transplants in China because of lower costs and shorter wait times.We evaluated outcomes of Egyptian patients who underwent liver transplants in China and address ethical concerns. Fifteen Egyptian patients (11 men, 4 women; mean age, 52 years) who underwent liver transplants in China were included. Preoperative data before traveling to China, reports from China, and follow-up data upon return were reviewed. Indications included hepatitis-C-related liver cirrhosis (n=9), hepatitis-C-related liver cirrhosis with hepatocellular carcinoma (n=4), and hepatitis-B-related liver cirrhosis (n=2). Nine patients were evaluated for living-related liver transplant but none of their potential donors was suitable. Three patients had advanced hepatocellular carcinoma and were not accepted for living-related liver transplant by any Egyptian center. Two patients had no living-related donor. One patient refused a living-related liver transplant in Egypt and elected to get a whole liver graft from China. Overall survival rate was 80.0% at 6 months and 73.3% at 12 months. There were 4 deaths; 2 occurred in China. Of the 11 surviving patients, 9 (82%) developed complications. Nineteen complications were seen in the 13 patients who were managed after returning from China. Major complications necessitating prolonged hospitalizations occurred in 4 patients. Two patients required further laparotomy. Although deceased-donor liver transplant in China could be an option for Egyptian patients with end-stage liver disease, patients and clinicians should be aware of potential outcomes and related ethical issues.

    Children with disorder of sex development (DSD) may be born with ambiguous genitalia. Decision-making in relation to sex assignment has been perceived as extremely disturbing and difficult to families and health care professionals. This is mainly due to a general paucity of information about the condition and an exaggerated feeling of stigma and shame associated with genital abnormalities. This is the first study in Egypt aimed at studying the psychosexual development and gender outcome of 40 Egyptian patients with 46,XY DSD focusing on the impact of social and religious factors. The patients were subjected to history-taking, pedigree analysis, full clinical examination, and cytogenetic studies. Hormonal, radiological investigations and molecular studies were performed when possible. Accordingly, they were classified into 4 groups: (1) sex chromosome aneuploid DSD (mixed gonadal dysgenesis) and (2) disorders of gonadal development (gonadal dysgenesis); (3) androgen biosynthesis defect (5alpha-reductase deficiency, 17beta-hydroxysteroid dehydrogenase deficiency), and (4) defect in androgen action (androgen insensitivity syndrome). The psychosexual development was assessed using adapted structured questionnaire and the Bem sex role inventory for patients below and above 12 years of age, respectively. Thirty-two patients (80%) were initially assigned as females; 3 patients with gonadal dysgenesis, 1 patient with 5alpha-reductase deficiency, and 1 patient with androgen insensitivity were reassigned as male. Male reassignment also was recorded in 5 patients with 17beta-hydroxysteroid dehydrogenase deficiency and one of them showed sex reversal twice. Gender outcome of our patients is elusive; the social component has a significant impact on the gender outcome in our society, even more than religion. We recommend that in the future more and more patients should be analyzed as well. These studies should be designed to emphasize the quality of life of DSD patients.

    Gaucher disease is the most frequent lysosomal storage disorder. Bone and lung involvement are two major causes of morbidity in this disease. D-dimer is a reliable indicator of active microvascular thrombosis, even in patients without overt hypercoagulation. This study aimed to assess D-dimer levels in Gaucher disease, correlating this marker to clinical characteristics and radiological parameters to investigate its role as a potential predictor for the occurrence and severity of skeletal and pulmonary manifestations. The study population consisted of 56 Egyptian patients with Gaucher disease, 36 had type 1 Gaucher disease (64.3%) and 20 had type 3 Gaucher disease (35.7%). Thirty healthy individuals were enrolled as a control group. D-dimer levels were significantly higher in all patients with Gaucher disease compared with controls (P < 0.001). Patients with type 3 showed significantly higher D-dimer concentrations compared with type 1 (P < 0.001). Pulmonary involvement was present in a significant proportion among type 3 Gaucher patients (P < 0.05), whereas bone changes were present in a higher percentage in type 1 compared with type 3 Gaucher patients. D-dimers were significantly higher in patients with abnormal MRI findings of the long bones and in those with ground glass appearance on high-resolution computerized tomography of the chest compared with patients with normal radiology (P < 0.001). Splenectomized patients displayed significantly higher D-dimer levels compared with nonsplenectomized patients (P < 0.001). Our results suggest that D-dimer is significantly elevated in Gaucher disease, particularly type 3, and may be considered as a potential marker of risk prediction of bone and lung involvement that could be used to monitor treatment response.

    Full Text Available Background: Chronic liver disease (CLD is a global medical problem. This disease is associated with increased hepatic oxidative stress. One of the antioxidant enzymes that protect cells against this stress is heme oxygenase-1 (HO-1.Objectives: This study aimed to investigate the mRNA expression of HO-1 in Egyptian patients with CLD and its relation to oxidative stress biomarkers.Patients and Methods: Levels of serum ferritin, carboxyhemoglobin, malondialdehyde (MDA, and erythrocyte-reduced glutathione (GSH were measured, and HO-1 mRNA expression was detected in 45 CLD patients (15 with nonalcoholic steatohepatitis [NASH], 15 with chronic hepatitis C, and 15 with liver cirrhosis and 15 healthy controls.Results: HO-1 mRNA expression was increased in patients with NASH, chronic hepatitis C, and liver cirrhosis compared to controls. The expression in cirrhotic patients was significantly higher than that in patients with NASH and chronic hepatitis C. Compared to controls, patients with NASH, chronic hepatitis C, and liver cirrhosis had higher levels of ferritin, carboxyhemoglobin, and MDA and lower levels of GSH. HO-1 mRNA expression was positively correlated with levels of carboxyhemoglobin, serum ferritin, and serum MDA and negatively correlated with levels of erythrocyte GSH in CLD patients.Conclusions: HO-1 mRNA expression was significantly increased in CLD patients, and the increase reflected the severity of the disease. The significant relationship between the increased HO-1 expression and oxidative stress biomarkers in patients with CLD suggests that HO-1 may play an important role in protecting the liver from oxidative stress-dependent damage. Therefore, induction of HO-1 could be a novel therapeutic option for CLD.

    To raise pharmacist awareness about the needs and concerns of our patients with visual impairment and to review useful strategies to foster medication adherence. As patient-centered pharmacists, we need to understand the challenges faced by our patients with low vision and tailor pharmaceutical care to best fit their needs. Evidence-based best practices in labeling and written communication have been developed by the American Foundation for the Blind in partnership with the American Society of Consultant Pharmacists. These recommendations include the use of specific font styles, minimum font size, and other standards known to enhance usability for those with limited vision. Recent advances in assistive technologies such as audio output and object recognition software can be used to ease the medication-taking process and effectively communicate important drug and safety information in a manner that can be understood by those with low vision. In July 2012, the Prescription Accessible Drug Labeling Promotion Act of 2012 (HR 4087) was signed into law. This new legislation is an addition to the Food and Drug Administration Safety and Innovation Act, which required the development and ultimate implementation by pharmacies of national best practices intended to improve the accessibility of prescription drug labeling for the visually impaired. As a patient-centered profession, we need to advocate for our patients with special needs by partnering with government and patient groups to support and enact legislation intended to enhance people's ability to adhere to drug therapy.

    Full Text Available OBJECTIVE: Somatic mutations of the nucleophosmin gene (NPM1, which alter the subcellular localization of the product, are the most frequent mutations in patients with acute myeloid leukemia. The aim of the study was to assess the prevalence and prognostic impact of NPM1 gene mutations in adult AML patients. METHODS: Polymerase chain reaction and single-strand conformation polymorphism (PCR-SSCP were used to screen 55 AML patients for mutations of NPM1 gene. RESULTS: NPM1 mutations were found in 12 (21.8% of 55 patients, significantly associated with higher total leukocytie count, marrow blast percentage (p=0.03 and p=0.02, respectively, and M5 subtype (p<0.001. Patients with NPM1 mutations had significantly higher complete remission rates (p=0.003 and a trend to lower rates of mortality, relapse and refractory disease (p=0.28, p=0.45 and p=0.08, respectively. Survival analysis showed significantly longer disease-free survival (mean 18.635±1.229 versus 11.041±1.250 months, p=0.044 and overall survival (mean 19.810±1.624 versus 12.063±1.244 months, p=0.041 in patients with NPM1 mutations compared with those without. Multivariate analyses confirmed NPM1 mutation as a significant independent predictor for disease-free survival (HR=0.066, p=0.001 and overall survival (HR=0.125, p=0.002. CONCLUSION: NPM1 mutation is a prognostic factor for a favorable outcome in Egyptian population. This finding is of major clinical importance since it strongly suggests that NPM1 mutations may allow one to divide the heterogeneous patient group of AML into prognostically different subgroups.

    The prevalence of Enterococcus faecalis (E. faecalis) infections among Egyptians with urinary tract infection (UTI), their antimicrobial susceptibility and mechanisms of resistance are under investigated. In this study, 300 urine samples were collected from UTI patients to identify E. faecalis. Antimicrobial susceptibility to 18 antimicrobial agents was tested. The presence of aac(6)-Ie-aph(2)Ia, erm(B) and mef(A/E) genes was examined by PCR. Fifty-seven (19%) isolates were identified as E. faecalis. All isolates were sensitive to teicoplanin and were completely resistant to nalidixic acid, cefotaxime and cefadroxil. Multi-drug-resistant (MDR) was found to be 100% with 45 different antibiotypes. The aac(6)Ia-aph(2)Ia gene was found in 100 and 90% of the isolates resistant to gentamicin at concentrations of 120 and 10 μg, respectively. erm(B) and mef(A/E) genes were present in 92.5% (37/40) and 2.5% (1/40) of erythromycin-resistant isolates, respectively. We conclude that there is a high prevalence of E. faecalis in UTI cases with a 100% MDR rate indicating a serious problem in treating infections by this organism in Egypt.

    Background and Objectives Use of pluripotent stem cells is an ideal solution for liver insufficiencies. This work aims is to evaluate the safety and feasibility of autologous stem cells transplantation (SCT) in Egyptian patients of liver cirrhosis on top of hepatitis C virus (HCV). Subjects and Results 20 patients with HCV induced liver cirrhosis were divided into 2 groups. Group I: included 10 patients with liver cirrhosis Child score ≥9, for whom autologous stem cell transplantation was done using granulocyte colony stimulating factor (G-CSF) for stem cells mobilization. Separation and collection of the peripheral blood stem cells was done by leukapheresis. G-CSF mobilized peripheral blood mononuclear cells (G-CSF PB-MNCs) were counted by flow cytometry. Stem cell injection into the hepatic artery was done. Group II: included 10 patients with HCV induced liver cirrhosis as a control group. Follow up and comparison between both groups were done over a follow up period of 6 months. The procedure was well tolerated. Mobilization was successful and the total number of G-CSF PB-MNCs in the harvests ranged from 25×106 to 191×106. There was improvement in the quality of life, serum albumin, total bilirubin, liver enzymes and the Child-Pugh score of group I over the first two-three months after the procedure. Conclusion SCT in HCV induced liver cirrhosis is a safe procedure. It can improve the quality of life and hepatic functions transiently with no effect on the life expectancy or the fate of the liver cirrhosis. PMID:26634069

    Full Text Available Objective: Budd-Chiari syndrome is a multifactorial disease in which several prothrombotic disorders may predispose patients to the development of thrombosis at this uncommon location (hepatic veins. The aim of this study was to determine the prevalence and characteristics of inherited thrombophilia in Egyptian Budd-Chiari syndrome patients.Materials and Methods: The study included 47 Budd-Chiari syndrome patients (20 children and 27 adults. Genotyping of Factor V G1691A (Leiden, prothrombin G20210A (PT, and methylenetetrahydrofolate reductase C677T were performed using real-time PCR and fluorescence melting curve detection analysis.Results: Factor V Leiden was observed in 29 patients (61.7%. It is the only factor that caused Budd-Chiari syndrome in 18 of the patients and in 5 of the patients with inferior vena cava involvement. Myeloproliferative disease was noted in 12 (25.5% patients, antiphospholipid syndrome in 5 (10.6%, and Behcet’s disease in 3 (6.4%. Interestingly, 3 of the children with Budd-Chiari syndrome had lipid storage disease.Conclusion: Factor V Leiden was a major etiological factor in Egyptian Budd-Chiari syndrome patients, which may have been related to the high frequency of this mutation in the study region. Factor V Leiden was also a strong thrombophilic factor and the leading cause of inferior vena cava thrombosis in these patients. Lipid storage disease should be included as a risk factor for Budd-Chiari syndrome.

    Warfarin is the mainstay of anticoagulation therapy worldwide. CYP2C9 and VKORC1 are two major genetic factors associated with inter-individual and inter-ethnic variability in the warfarin dose. This study aims to assess the impact of VKORC1-1639G>A polymorphism and the most common CYP2C9 variant alleles (*2 and *3) on warfarin response in Egyptian patients. Genetic analysis of VKORC1-1639G>A and CYP2C9*2, CYP2C9*3 was performed using real-time PCR system. Patients maintained on a constant dose targeting an international normalized ratio range of 2-3.5 for at least three consecutive times were considered as good candidates. A stepwise linear regression analysis was used to determine the independent effects of genetic and non-genetic factors on daily warfarin dose requirements. Patients carrying VKORC1 and CYP2C9 variant genotypes needed a 44.8 % lower mean daily warfarin dose as compared to wild types. Patients with G allele for VKORC1-1639G>A had a significantly higher number of thromboembolic complications per month during therapy. On the first 30 days of therapy, presence of a variant allele either in VKORC1 or in CYP2C9 was associated with increased time required to achieve stable dosing. Multiple regression analysis showed that, VKORC1-1639G>A, age, CYP2C9*3, and smoking status explained 43.4 % of the overall variability in the warfarin dose. VKORC1-1639G>A and CYP2C9 polymorphisms contribute to the difference in warfarin dose requirements and quality of anticoagulation amongst Egyptian patients. Study results support using personalized warfarin treatment in Egyptian patients.

    Myocardial siderosis in thalassemia major remains the leading cause of death in developing countries. Once heart failure develops, the outlook is usually poor with precipitous deterioration and death. Cardiovascular magnetic resonance (CMR) can measure cardiac iron deposition directly using the magnetic relaxation time T2*. This allows earlier diagnosis and treatment and helps to reduce mortality from this cardiac affection. This study aims to determine the prevalence of cardiac siderosis in Egyptian patients who are heavily iron loaded and its relation to liver iron concentration, serum ferritin, and left ventricular ejection fraction. Eighty-nine β-thalassemia patients receiving chelation therapy (mean age of 20.8 ± 6.4 years) were recruited in this study. Tissue iron levels were determined by CMR with cardiac T2* and liver R2*. The mean ± standard deviation (range) of cardiac T2* was 28.5 ± 11.7 ms (4.3 to 53.8 ms), the left ventricular ejection fraction (LVEF) was 67.7 ± 4.7 % (55 to 78 %), and the liver iron concentration (LIC) was 26.1 ± 13.4 mg Fe/g dry weight (dw) (1.5 to 56 mg Fe/g dw). The mean serum ferritin was 4,510 ± 2,847 ng/ml (533 to 22,360 ng/ml), and in 83.2 %, the serum ferritin was >2,500 ng/ml. The prevalence of myocardial siderosis (T2* of serum ferritin of 4,996 ng/ml. There was no correlation between T2* and age, LVEF, LIC, and serum ferritin (P = 0.65, P = 0.085, P = 0.99, and P = 0.63, respectively). Severe cardiac siderosis (T2* of serum ferritin results were 29.8 ± 17.0 mg/g and 7,200 ± 6,950 ng/ml, respectively. In this group of severe cardiac siderosis, T2* was also not correlated to age (P = 0.5), LVEF (P = 0.14), LIC (P = 0.97), or serum ferritin (P = 0.82). There was a low prevalence of myocardial siderosis in the Egyptian thalassemia patients in spite of very high serum ferritin and high LIC. T2* is the best test that can identify at-risk patients who can be

    AIM: Smoking may affect adversely the response rate to interferon-α. Our objective was to verify this issue among chronic hepatitis C patients.METHODS: Over the year 1998, 138 chronic hepatitis C male Egyptian patients presenting to Cairo Liver Center,were divided on the basis of smoking habit into: group Ⅰ which comprised 38 smoker patients (>30 cigarettes/d)and group Ⅱ which included 84 non-smoker patients.Irregular and mild smokers (16 patients) were excluded.Non eligible patients for interferon-α therapy were excluded from the study and comprised 3/38 (normal ALT) in group Ⅰ and 22/84 in group Ⅱ (normal ALT, advanced cirrhosis and thrombocytopenia). Group Ⅰ was randomly allocated into 2 sub-groups: group Ⅰa comprised 18 patients who were subjected to therapeutic phlebotomy while sub-group Ⅰb consisted of 17 patients who had no phlebotomy. In sub-group Ⅰa, 3 patients with normal ALT after repeated phlebotomies were excluded from the study. Interferon-α 2b 3 MU/TIW was given for 6 mo to 15 patients in group Ⅰa, 17 patients in group Ⅰb and 62 patients in group Ⅱ.Biochemical, virological end-of- treatment and sustained responses were evaluated.RESULTS: At the end of interferon-α treatment, ALT was normalized in 3/15 patients (20%) in group Ⅰa and 2/17patients (11.8%) in group Ⅰb compared to17/62 patients (27.4%) in group Ⅱ (P=0.1). Whereas 2/15 patients (13.3%)in group Ⅰa. and 2/17 patients (11.8%) in group Ⅰb lost viraemia compared to 13/62 patients (26%) in group Ⅱ (P = 0.3). Six months later, ALT was persistently normal in 2/15 patients (13.3%) in group 1a and 1/17 patients (5.9%) in group Ⅰb compared to 9/62 patients (14.5%) in group Ⅱ (P= 0.47). Viraemia was eliminated in 1/15 patients (6.7%) in group Ⅰa and 1/17 patients (5.9%) in group Ⅰb compared to 7/62 patients (11.3%) in group Ⅱ, but the results did not mount to statistical significance (P = 0.4).CONCLUSION: Smokers suffering from chronic hepatitis C tend

    Morquio A disease (Mucopolysaccharidosis IVA, MPS IVA) is an autosomal recessive lysosomal storage disorder caused by deficient activity of the enzyme N-acetylgalactosamine-6-sulfate sulfatase (GALNS) encoded by the GALNS gene. This deficiency leads to a decreased ability to degrade the glycosaminoglycans (GAGs) keratan sulfate and chondroitin 6-sulfate, thereby causing their accumulation within the lysosomes and consequently prominent skeletal and visceral abnormalities. Clinical evaluation and biochemical GALNS enzyme activity determination were carried out for the patients from four unrelated Egyptian families. Mutational analysis was performed to PCR products by sequencing of the 14 exons and exon-intron boundaries of GALNS gene for the 4 patients. Sequence analysis revealed four novel mutations; three nonsense mutations (p.Q12X, p.Q220X, p.Y254X) and one missense mutation, p.D40G. All four patients were offspring of consanguineous marriages and were homozygous for the corresponding mutation. The activity of the GALNS enzyme was below normal reference range in all of them. The p.Q12X and p.Y254X were associated with severe MPS IVA phenotype. Molecular analysis of GALNS gene revealed four novel mutations in four different Morquio A Egyptian patients.

    The creation of a stoma changes bodily appearance and function, which can affect quality of life (QOL). A descriptive study using the Short Form 36 (SF-36) questionnaire, an instrument that measures 8 physical and mental health concepts, was conducted to quantify QOL among patients with a stoma and to interpret how stoma creation affects their lives. Participants included a convenience sample of persons served by an outpatient surgery clinic in an Egyptian university hospital in Cairo between August 2013 and January 2015. Potential participants had to be 18 years of age or older, have undergone intestinal stoma surgery, live at home, be willing to participate, and not be hospitalized or have physical or psychological limitations that prevent them from participating in self-care. General demographic data and disease characteristics/reasons for stoma creation collected included age, gender, and marital status; stoma type, design, and duration; and stoma problems/complica- tions. Every patient completed the questionnaire individually or, if necessary, with the researcher's assistance; the interview took approximately 10 to 15 minutes. Demographic data were collected after stoma creation from the patient's medical pro les using a predesigned form. The SF-36 scores were linearly converted to a 0 to 100 scale, with higher scores indicating bet- ter QOL; scores were considered excellent (100), very good (84-99), good (61-83), fair (25-60), and poor (0-24). Data were analyzed using descriptive analysis. Independent sample t-tests and 1-way analysis of variance tests were used to compare variables, and a 2-tailed probability value of 0.05 was used to determine the level of signi cance. Mean age of the 96 par- ticipants was 44.12 ± 12.83 years, and most participants were male (58.33%), married (87.5%), and had a permanent stoma (60.42%) with mean stoma duration of 2.86 ± 0.43 years. The majority of patients (68.75%) had a colostomy. All patients (100%) reported 1 or more

    Patients with diabetes mellitus (DM) have increased mortality and morbidity of cardiovascular diseases compared with non-diabetic patients. The role of apolipoprotain E in lipid metabolism and cholesterol transport is well established. Apolipoprotein E gene (APO E) polymprphism that confers susceptibility to or protection from CAD in patients with type 2 DM may be quite different in different ethnic populations. We aimed to determine the frequencies of allelic variants of APO E in Egyptian population and to examine the relationship between APO E polymorphism and risk of coronary artery disease (CAD) in Egyptian type 2 diabetic patients. The study included 35 diabetic patients with CAD (group 1), 35 diabetic patients without CAD (group II) and 30 control subjects. All were subjected to history taking, clinical examination, and laboratory investigations for lipid profile and APO E genotyping by PCR-RFLP. Results revealed that epsilon3 allele was the commonest among the studied subjects (84%). The frequencies of epsilon2 and epsilon4 alleles were higher in group I (24.3% and 8.6% respectively) than group II and controls. The frequency of E2/E2, E2/E3, and E4/E3 genotypes was significantly higher in group I than group II and controls. Comparing group I vs. controls and group I vs. group II, multivariate analysis demonstrated significantly increased risk for CAD with epsilon4 and epsilon2 alleles vs. E3 (OR=7.02 and 4.97 respectively). In Conclusion, epsilon4 and E2 alleles are associated with higher risk of CAD in type2 DM than epsilon3 allele. Larger scale studies are still needed to either confirm or modify these results.

    Full Text Available Introduction: Over the past three decades, the number of people with diabetes mellitus (DM has more than doubled globally, making it one of the most important public health challenges to all nations. Aldose reductase (AR is a rate-limiting enzyme in the polyol pathway, which has been implicated in the pathogenesis of diabetic microvascular complications; however, the association of the AR gene with diabetic macrovascular complications has rarely been investigated. Aim: The study aimed to identify the possible association between C(-106 T polymorphism of the AR gene and diabetic macroangiopathy in a cohort of Egyptian patients with type 2 DM. Settings and Design: This study was conducted on 100 Egyptian subjects, the control group (n = 20 and the patient group (n = 80 with type 2 diabetes which were further subdivided into two subgroups with (n = 48 and without macroangiopathic complications (n = 32 as evidenced by carotid intima-media thickness, electrocardiography (ECG ischemic changes, cerebrovascular insufficiency, and peripheral vascular insufficiency. Subjects and Methods: All studied subjects were subjected to detailed history taking, clinical examination, ECG, carotid ultrasonography, routine laboratory investigations, and molecular studies including the detection of AR C(-106 T gene polymorphisms using the polymerase chain reaction (PCR/restriction fragment length polymorphism technique. Results: The genotype distribution and allele frequency of AR C(-106 T showed no statistical significance also the genotypes were not associated with any of the different studied parameters. Conclusions: The results suggest that the C(-106 T polymorphism in the AR gene is not involved in the pathogenesis of macroangiopathy in type 2 diabetes.

    Full Text Available The interindividual variations in the capacity of transforming growth factor-β1 (TGF-β1 production have been ascribed to genetic polymorphisms in TGF-β1 gene. As pathogenesis of HBV has a genetic background, this preliminary study was designed to assess the impact of TGF-β1 (T29C on the susceptibility of Egyptians to HBV infection. Genotyping was performed using single stranded polymorphism-polymerase chain reaction (SSP-PCR in 65 Egyptian hepatitis B patients and 50 healthy controls. TGF-β1 plasma levels were measured using Enzyme-linked immunosorbent assay (ELISA. The frequency of CC genotype was significantly higher (P<0.05 in HBV patients compared to controls. On the contrary, TC genotype did not show significant difference in both groups. TT genotype was significantly higher (P<0.01 in controls than HBV patients. Our current preliminary data revealed that the frequency of the genotypes in the controls were within Hardy-Weinberg equilibrium (HWE while the patients group was out of HWE (P<0.01. TGF-β1 was significantly (r=-0.684; P<0.001 deceased in the sera of patients as compared to normal subjects. Depending on our preliminary work, CC genotype may act as a host genetic factor in the susceptibility to HBV infection in Egyptians. Taken together, the current data pointed to the importance of polymorphism of TGF-β1 gene (T29C in HBV infection.

    This study aims to provide further insight into the phenotypic heterogeneity of Klinefelter syndrome (KS) by presenting clinical, hormonal, and genetic data from a large series of Egyptian infertile patients with KS. A retrospective case series of KS patients was studied over a period from January 2003 to April 2010. All patients underwent a complete history and physical examination; color duplex examination; semen analysis; measurement of total testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and prolactin (PRL); and chromosomal typing. Mosaic KS diagnosis was confirmed by fluorescence in situ hybridization. The series included 216 KS patients (198 nonmosaic, 16 mosaic, and 2 KS variants). Typical clinical signs of hypoandrogenism were observed in 86% of patients. Gynecomastia affected 20.8% of the patients. Eunuchoidal body proportions, with arm span exceeding height and lower segment length exceeding upper segment length, were detected in 43.9% and 64.4% of the patients, respectively. In all patients, a reduction in testicular size and azoospermia were detected. Normal levels of T, FSH, LH, E2, and PRL were detected in 44.5%, 3.7%, 3.3%, 93.5%, and 91.2% of patients, respectively. Differences were not significant between patients with classic KS and those with mosaic KS in terms of the frequency of clinical signs of hypoandrogenism, gynecomastia, low T concentrations, or high concentrations of FSH, LH, E2, and PRL (all P > .05). The results of the current study emphasize the heterogeneous clinical, hormonal, and genetic phenotype of infertile KS patients. Our findings support the usefulness of cytogenetic studies in infertile patients showing small testicular size and azoospermia, regardless of the presence of other clinical or endocrine findings.

    Full Text Available Not much is known about how well stroke patients are able to perform motor imagery (MI and which MI abilities are preserved after stroke. We therefore applied three different MI tasks (one mental chronometry task, one mental rotation task, and one EEG-based neurofeedback task to a sample of postacute stroke patients (n=20 and age-matched healthy controls (n=20 for addressing the following questions: First, which of the MI tasks indicate impairment in stroke patients and are impairments restricted to the paretic side? Second, is there a relationship between MI impairment and sensory loss or paresis severity? And third, do the results of the different MI tasks converge? Significant differences between the stroke and control groups were found in all three MI tasks. However, only the mental chronometry task and EEG analysis revealed paresis side-specific effects. Moreover, sensitivity loss contributed to a performance drop in the mental rotation task. The findings indicate that although MI abilities may be impaired after stroke, most patients retain their ability for MI EEG-based neurofeedback. Interestingly, performance in the different MI measures did not strongly correlate, neither in stroke patients nor in healthy controls. We conclude that one MI measure is not sufficient to fully assess an individual’s MI abilities.

    We evaluated the ability of circulating anodic antigen (CAA) to identify infection with Schistosoma mansoni in a prospective cohort study of 257 Egyptian men, 147 with infection diagnosed by repeated Kato thick smears, and 110 without detectable infection. The CAA levels were obtained and the stool examinations were performed two weeks and one, two, four, and six months after praziquantel therapy for infected men. A CAA enzyme-linked immunosorbent assay was repeated twice on subjects who were otherwise negative for schistosomiasis. Circulating anodic antigen was detected in 117 cases, with an overall test sensitivity before treatment of 0.8. Sensitivity was related to the intensity of infection, ranging from 1.00 with > 400 eggs per gram (epg) of feces to 0.60 for those with or = 4. We conclude that CAA has moderate sensitivity and excellent specificity when used to identify infection with schistosomiasis, as well as to monitor the results of therapy after at least one month after treatment.

    Full Text Available Duchenne muscular dystrophy (DMD and Becker muscular dystrophy (BMD are allelic disorders caused by mutations within the dystrophin gene. Our study has identified 100 Egyptian families collected from the Human Genetics Clinic, National Research Center, Cairo. All cases were subjected to complete clinical evaluation pedigree analysis, electromyography studies, estimation of serum creatine phosphokinase enzyme (CPK levels and DNA analysis. Multiplex PCR using 18 pairs of specific primers were used for screening of deletion mutations within the dystrophin gene. A frequency of 55% among the families. Sixty per cent of detected deletions involved multiple exons spanning the major or the minor hot spot of the dystrophin gene. The remainder 40% which mainly involved exon 45. Comparing these findings with frequencies of other countries it was found that our figures fall within the reported range of 40%– for deletions. The distribution of deletions in our study and other different studies was variable and specific ethnic differences do not apparently account for specific deletions. In addition this study concluded that employment of the 18 exon analysis is a cost effective and a highly accurate (97% to launch a nationwide program.

    The Wilms' tumor (WT1) gene mutations were detected in patients with most forms of acute leukemia. However, the biological significance and the prognostic impact of WT1 mutation in Egyptian patients with acute myeloid leukemia with normal karyotype (AML-NK) are still uncertain. We aimed to evaluate the incidence and clinical relevance of WT1 gene mutations in acute myeloid leukemia with normal karyotype (AML-NK). Exons 7 and 9 of WT1 were screened in samples from 216 adult NK-AML using polymerase chain reaction single-strand conformation polymorphism techniques. Twenty-three patients (10.6%) harbored WT1 mutations. Younger ages and higher marrow blasts were significantly associated with WT1 mutations (P = 0.006 and 0.003 respectively). Complete remission rates were significantly lower in patients with WT1 mutations than those with WT1 wild-type (P = 0.015). Resistance, relapse, and mortality rates were significantly higher in patients with WT1 mutations than those without (P = 0.041, 0.016, and 0.008 respectively). WT1 mutations were inversely associated with NPM1 mutations (P = 0.007). Patients with WT1 mutations had worse disease-free survival (P mutations independently predicted worse DFS (P mutational status. In conclusion, WT1 mutations are a negative prognostic indicator in intensively treated patients with AML-NK, may be a part of molecularly based risk assessment and risk-adapted treatment stratification of patients with AML-NK.

    Hepatitis delta virus (HDV) usually have an unfavorable clinical outcome in chronic hepatitis B virus (HBV) patients. In Egypt, data about epidemiology, the spectrum of disease, and impact of HDV on HBV infection are rare. To assess the prevalence, clinical and virological characteristics of HDV infection among Egyptian patients with chronic HBV. Adult patients with Hepatitis B surface antigen (HBsAg)-positive were evaluated for the presence of HDV using anti HDV-IgG and HDV RNA by RT-PCR. Routine laboratory investigations, genotypes and subtypes for both HBV and HDV, abdominal sonography, and transient elastography (TE) were done. Liver biopsy was performed only in whenever indicated. One hundred and twenty-one treatment-naïve chronic HBV patients were included. Wild HBV genotype-D2 was found in 98.2% and 81.9% were HBeAg negative. Prevalence of HDV was 8.3% by anti-HDV IgG and 9.9% by RT-PCR. Wild HDV genotype-IIb was reported in 83.3%. HDV infection was more common in males, 90.9% of delta patients were HBeAg negative. Compared to the mono-infected HBV, concomitant HBV/HDV infection was not associated with more derangment in ALT nor advanced stage of fibrosis. 66.7% of HDV patients had significantly lower HBV-DNA level compared to the non-delta patients (P infection was associated with negative HBeAg status, reduction of HBV replication, but neither influenced the clinical course nor increased significant liver damage risk. © 2015 Wiley Periodicals, Inc.

    Simeprevir plus sofosbuvir (SIM/SOF) regimen was recommended by professional guidelines for certain patients with HCV genotype 1 infection and there is lack of data about this regimen in patients with genotype 4 infection. To evaluate the efficacy and safety of this regimen in Egyptian patients with chronic HCV genotype 4 infection in the real world. Multicentre observational study included 583 patients with HCV genotype 4 infection who began 12 weeks of treatment with SIM plus SOF. Demographic, clinical and virological data as well as adverse outcomes were collected. Treatment naïve patients were 342 (59%) of all included patients, 45% of patients had severe fibrosis (F3 and F4) while 55% had mild fibrosis (F1 and F2) and the primary outcome was sustained virological response (SVR). The overall SVR rate was 95.7% (558 out of 583 patients). In total, SVR12 in naïve patients with mild fibrosis score (F1 and F2) was achieved in 98.9% (94/95) for F1 and 98.1% (105/107) for F2, while naïve patients with severe fibrosis (F3 and F4) achieved SVR of 97.7% (86/88) for F3 and (42/52) 80.8% for F4. SVR in patients with previous interferon treatment achieved in 100% (45/45) for patients with F1 and 98.7% (74/75) for F2. While 94.7% (72/76) in experienced patients with F3; and 88.9% (40/45) for F4 achieved SVR12. Notable side effects included rash in 21 patients, photosensitivity in 18 patients, pruritus in 44 patients and hyperbilirubinemia in 42 patients. A 12-week regimen of simeprevir/sofosbuvir was efficacious and well tolerated by treatment-naïve and treatment-experienced patients with chronic HCV genotype 4.

    Full Text Available Abstract Background HCV is one of the major health problems in Egypt, where it is highly prevalent. Genotype 4 is the most common genotype of HCV and its response to treatment is still a controversy. Methods HCV genotype 4 quasispecies diversity within the 5' untranslated region (5'UTR was studied in a series of 22 native Egyptian patients with chronic hepatitis C virus with no previous treatment who satisfied all NIH criteria for combined treatment of pegylated IFN and ribavirine and was correlated with the outcome of treatment. The study also included 7 control patients with no antiviral treatment. HCV sequencing was done using the TRUGENE HCV 5-NC genotyping kit. Results At the 48th week of treatment, 15 patients (68% showed virological response. Whereas HCV-RNA was still detected in 7 patients (32% in this period; of those, 6 experienced a partial virological response followed by viral breakthrough during treatment. Only one patient did not show any virological or chemical response. The four females included in this study were all responders. There was a significant correlation between the response rate and lower fibrosis (p = 0.026 as well as the total number of mutation spots (including all the insertions, deletions, transitions and transversions (p = 0.007, p = 0.035. Conclusion Patients who responded to interferon treatment had statistically significant less number in both transitions (p = 0.007 and the genetic distances between the quasispecies (p = 0.035. So, viral genetic complexity and variability may play a role in the response to IFN treatment. The consensus alignment of all three groups revealed no characteristic pattern among the three groups. However, the G to A transitions at 160 was observed among non responders who need further study to confirm this observation.

    Full Text Available INTRODUCTION: Systemic lupus erythematosus (SLE afflicts young people disproportionately, often at a crucial time in their lives when they are trying to establish relationships, start families and launch careers. As a result, persons with SLE may experience a wide range of physical and psychosocial problems that are not always fully captured by descriptions of the disease’s physiological consequences alone. METHODS: In order to characterize the spectrum of the effects of SLE with regards to disease activity and its impact on the quality of life (QoL, a case control study involving 59 SLE Egyptian patients (mean age 28.6 years , 94.9% females and 20 healthy controls was undertaken. Disease activity was measured by SLE Disease Activity Index (SLEDAI, and quality of life was measured by Short Form 36 health questionnaire (SF-36. RESULTS: Mucocutaneous and hematological manifestations were present in most of the patients and arthralgia in half of them. All domains of SF-36 including general health, physical functions, physical limitations, energy/fatigue, emotional well-being, pain, social functions, and health changes were significantly lower in SLE patients compared to controls. Except for emotional limitations, all domains were correlated with disease activity and low in class IV-V lupus nephritis. CONCLUSION: Physicians should focus on QoL and how to improve it; health education regarding the negative impact of disease activity on the patients should be given attention. The results of QoL studies help physicians to understand and provide better support to SLE patients beside rapid meticulous control of disease activity

Our study included 657 HCV-infected patients with genotype 4 who received interferon-based combination therapy. Patients were divided into two groups based on their response to therapy: 356 were responders, and 301 were non-responders. Patients were compared to 160 healthy controls. All patients and controls underwent a thorough physical examination, measurement of body mass index (BMI) and the following laboratory tests: serum alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, albumin, total bilirubin, direct bilirubin, prothrombin time, prothrombin concentration, INR, complete blood count, serum creatinine, fasting blood sugar, HCV antibody, and hepatitis B surface antigen. All HCV patients were further subjected to the following laboratory tests: HCV-RNA using quantitative polymerase chain reaction (PCR), antinuclear antibodies, thyroid-stimulating hormone, an LDL receptor (LDLR) genotype study of LDLR exon8c.1171G>A and exon10c.1413G>A using real-time PCR-based assays, abdominal ultrasonography, ultrasonographic-guided liver biopsy, and histopathological examination of liver biopsies. Correlations of LDL receptor polymorphisms with HAI, METAVIR score, presence of steatosis, and BMI were performed in all cases. There were no statistically significant differences in response rates between the different types of interferon used or LDLR exon10c.1413G>A. However, there was a significant difference in the frequency of the LDL receptor exon8c.1171G>A genotype between cases (AA: 25.9%, GA: 22.2%, GG: 51.9%) and controls (AA: 3.8%, GA: 53.1% and GG: 43.1%) (P A polymorphism between responders (AA: 3.6%, GA: 15.2%, GG: 81.2%) and non-responders (AA: 52.2%, GA: 30.6%, GG: 17.2%) (P A predominated in cases and controls over the A allele, and a statistically significant association with

    Background Egypt has the highest prevalence of a difficult to treat chronic hepatitis C virus (HCV), genotype 4. Pretreatment factors could guide individualization of therapy which aids in treatment optimization and interleukin IL28B gene polymorphism has been shown to closely relate to HCV treatment response. Polymorphisms in genes encoding inhibitors of T-cell response, which have role in disease progression as Programmed Cell Death 1 (PD-1), and Cytotoxic T-Lymphocytes Antigen-4 (CTLA-4), could be candidate markers predicting treatment response. Methods This cohort study consisted of 200 chronic HCV genotype 4 infected patients treated with PegIFN α-2a and RBV in 2 hepatology centers. Genotyping of the polymorphisms in the IL28B gene region (rs12979860), PD1.3 (rs11568821) and CTLA-4 (rs231775) was performed on DNA collected from each patient using TaqMan® genotyping assay. Groups were classified according to response into sustained virological responders (SVR), or non-responders (NR). A multivariate logistic regression analysis was used to identify potential markers, host pretreatment clinical and viral predictive factors including viral load, insulin resistance, and alpha fetoprotein (AFP) related to treatment response. Results Our results showed that in a multivariate analyses IL28B C/C genotype was the most significant predictor for SVR (OR = 10.86; p<0.0001) followed by AFP (OR = 0.915; p = 0.001) then CTLA-4/G genotypes (OR = 1.948; p = 0.022). However, PD-1.3/A genotypes and platelets count were significantly related to response in univariate analysis only (OR = 1.973; p = 0.023; OR = 1.007; p = 0.009 respectively). Conclusion IL28B SNP, AFP level, and CTLA-4 SNP could be used in conjunction to predict treatment response in HCV genotype 4 infected Egyptian patients. PMID:27100663

Stroke is increasingly recognized as an important cause of cognitive problems and has been implicated in the development of both Alzheimer's disease and vascular dementia. The prevalence of cognitive impairment after stroke is high, and their combined effects significantly increase the cost of care and health resource utilization, with reflections on hospital readmissions and increased mortality rates. There is also substantial evidence that vascular risk factors (such as hypertension, diabetes, obesity, dyslipidemia, and tobacco smoking are independently associated with an increased risk of cognitive decline and dementia. Thus, a successful management of these factors, as well as optimal acute stroke management, might have a great impact on the development of cognitive impairment. Notwithstanding, the pathological link between cognitive impairment, stroke, and vascular risk factors is complex and still partially unclear so that further studies are needed to better elucidate the boundaries of this relationship. Many specific pharmacological treatments, including anticholinergic drugs and antihypertensive medications, and nonpharmacological approaches, such as diet, cognitive rehabilitation, and physical activity, have been studied for patients with vascular cognitive impairment, but the optimal care is still far away. Meanwhile, according to the most recent knowledge, optimal stroke care should also include cognitive assessment in the

    Telerehabilitation is one of the newest branches of telemedicine which has been developed because patients need regular trainings outside the medical institution but still under specialist supervision. It helps maintain regularity of exercises and reduces costs. The professional and advanced systems for telerehabilitation are presented in papers, however, there is still lack of development of minor systems which provide therapeutic values and are more accessible to people. Therefore we focus on a solution for hand telerehabilitation of poststroke patients, based solely on a personal computer and camera. We focused on the manipulative hand (fingers, metacarpus, wrist) movements trainings for patients with cerebral palsy. The contact between patient and physiotherapist is provided by using web cameras and web service. Additionally, the camera can be used to monitor the effectiveness of performed exercises. Computer vision system keeps track of the patient's hand movement. The digital image processing is used to detect if the patient performs exercises correctly. We created web service and software application TeleReh that provides therapeutic values for the hand impaired people. The system created was evaluated by three physiotherapists, one doctor and a cerebral palsy patient. Our solution applies to all patients who have undergone basic rehabilitation in hospital and need to continue hand rehabilitation at home. The main advantages are: easy adaptation to the individual needs and abilities, monitoring the progress by using automatically generated reports after each training session. It is worth noticing that discussion between IT specialists, rehabilitants and patients was necessary to achieve good results.

    Malnutrition is an established risk factor for adverse clinical outcomes. Our aim was to assess nutritional status among geriatric trauma patients. We enrolled 169 consecutive patients (⩾70 years) admitted to the Geriatric Traumatology Centre (University Hospital Zurich, Switzerland). On admission to acute care, nutritional status was assessed with the mini nutritional assessment (score23.5=normal). At the same examination, we assessed mental (Geriatric Depression Scale; GDS) and cognitive function (Mini-Mental State Examination; MMSE), frailty status (Fried Scale), and number of comorbidities and medications. Further, discharge destination was documented. All analyses were adjusted for age and gender. A total of 7.1% of patients were malnourished and 49.1% were ARM. Patients with reduced mental health (GDS⩾5: 30.5 vs 11.5%; P=0.004), impaired cognitive function (MMSE⩽26: 23.6±0.5 vs 26.0±0.6; P=0.004), prevalent frailty (32.5 vs 8%; Pnutritional status (M+ARM). Further, M+ARM patients were twice as likely to be discharged to destinations different to home (odds ratio=2.08; confidence interval 1.07-4.05). In this consecutive sample of geriatric trauma patients, 56.2% had an M+ARM upon admission to acute care, which was associated with indicators of worse physical, mental and cognitive health and predicted a more than twofold greater odds of being discharged to a destination other than home.

    Factor V Leiden 1691G/A and prothrombin gene 20210G/A mutations are the most common genetic defects leading to thrombosis. This work aimed to study the FV Leiden and the prothrombin gene polymorphism in adult Egyptian patients with acute leukemia and their importance in thrombophilia screening. The study included 76 patients with acute leukemia and 100 healthy controls. Genotyping was done by real-time polymerase chain reaction technique. For factor V Leiden, the frequency of G/A mutation conferred more than 2.5-fold of increased risk of (OR 2.639 95 % CI 1.045-6.669). The frequency of factor V Leiden combined (G/A + A/A) genotypes conferred 2.83-fold of increased risk (OR 2.828, CI 1.13-7.075), The A allele conferred almost threefold increased risk (OR 2.824, 95 % CI 1.175-6.785). Despite higher frequency in patients compared to controls, there was no risk of association between prothrombin gene mutation and acute leukemia in adult Egyptians nor was there between combined genotypes of prothrombin gene mutation and factor V Leiden.

    Full Text Available Hepatitis C is a significant public health problem in Egypt where the highest prevalence (14.7% of hepatitis C virus (HCV exists. HCV prevalence is even higher among clinical populations and groups at risk of exposure to infection. Chronic HCV infection is associated with several hematological complications that may necessitate bone marrow (BM examination. The aim of this study is to estimate HCV prevalence among patients referred for BM examination and to explore hematological and BM findings among HCV positive patients. One hundred adult patients referred for BM examination were included in the study and screened for HCV antibodies. Patients’ clinical, hematological, and BM findings were recorded. The seroprevalence of HCV among patients referred for BM examination was 42%. The most common indication for BM examination among HCV positive patients was peripheral cytopenias (88.1%. The most common cytopenia detected was thrombocytopenia (85.7%. The most common diagnosis among HCV positive patients was hypersplenism (52.4% followed by B-lymphoproliferative disorders (19% and then immune thrombocytopenic purpura (11.9%. In conclusion, HCV prevalence among patients referred for BM examination is higher than that estimated in the general population. Patients with unexplained peripheral cytopenias should be tested for HCV.

    Cognitive damage in heart failure (HF) involves different domains thus interfering with the ability for single patient to self-care and to cope with treatment regimens, modifying symptoms and health behaviours. Many cerebral and functional changes were detected in brain imaging, involving areas of both grey and white matter deputed to cognition. Although various instruments are available to explore cognition, no consensus was obtained on better tools to be used in HF population. Reduction in cerebral blood flow, decreased cardiac output, altera-tions of cerebrovascular reactivity and modification of blood pressure levels are the main features involved in the etiopathogenetic mecha-nisms of cognitive deficit. Several cardiac variables, laboratory parameters, demographic and clinical elements were studied for their possible relation with cognition and should be properly evaluated to define patients at increased risk of impairment. The present review gathers avail-able data pointing out assured information and discussing possible areas of research development.

    Occult hepatitis B infection is characterized by the presence of hepatitis B virus (HBV) DNA in the serum in the absence of hepatitis B surface antigen (HBsAg). Prevalence of hepatitis C virus (HCV) infections in Egypt is among the highest in the world. In this study, we aim at analysing the rates of occult HBV infections among HCV paediatric cancer patients in Egypt. The prevalence of occult HBV was assessed in two groups of paediatric cancer patients (HCV positive and HCV negative), in addition to a third group of paediatric noncancer patients, which was used as a general control. All groups were negative for HBsAg and positive for HCV antibody. HBV DNA was detected by nested PCR and real-time PCR. HCV was detected by real-time PCR. Sequencing was carried out in order to determine HBV genotypes to all HBV patients as well as to detect any mutation that might be responsible for the occult phenotype. Occult hepatitis B infection was observed in neither the non-HCV paediatric cancer patients nor the paediatric noncancer patients but was found in 31% of the HCV-positive paediatric cancer patients. All the detected HBV patients belonged to HBV genotype D, and mutations were found in the surface genome of HBV leading to occult HBV. Occult HBV infection seems to be relatively frequent in HCV-positive paediatric cancer patients, indicating that HBsAg negativity is not sufficient to completely exclude HBV infection. These findings emphasize the importance of considering occult HBV infection in HCV-positive paediatric cancer patients especially in endemic areas as Egypt.

    Full Text Available Abstract Background Autism is a biological disorder with clearly defined phenomenology. Studies from the Middle East on this topic have been particularly rare. Little is known about the influence of culture on clinical features, presentations and management of autism. The current study was done to compare characteristics of autism in two groups of Egyptian as well as Saudi children. Methods The sample included 48 children with Autism Spectrum Disorder. They were recruited from the Okasha Institute of Psychiatry, Ain Shams University, Cairo, Egypt and Al-Amal Complex for Mental Health, Dammam, Kingdom of Saudi Arabia. They were grouped into an Egyptian group (n = 20 and a Saudi group (n = 28. They were assessed both clinically and psychometrically using the GARS, the Vineland adaptive behavioral scale, and the Stanford Binnet IQ test. Results Typical autism was more prevalent than atypical autism in both groups. There were no statistically significant differences in clinical variables like regression, hyperactivity, epilepsy or mental retardation. Delayed language development was significantly higher in the Egyptian group while delay in all developmental milestones was more significant in the Saudi group. The Vineland communication subscale showed more significant severe and profound communication defects in the Saudi group while the Gilliam developmental subscale showed significantly more average scores in the Egyptian group. Both groups differed significantly such that the age of noticing abnormality was younger in the Saudi group. The age at diagnosis and at the commencement of intervention was lower in the Egyptian group. The Saudi group showed a higher percentage of missing examinations, older birth order and significantly higher preference to drug treatment, while the Egyptian group showed a high preference to behavioral and phoniatric therapies, higher paternal and maternal education, higher employment among parents and higher family

    Full Text Available Background and Aims. Treatment of hepatic hydrothorax is a clinical challenge. Chest tube insertion for hepatic hydrothorax is associated with high complication rates. We assessed the use of pigtail catheter as a safe and practical method for treatment of recurrent hepatic hydrothorax as it had not been assessed before in a large series of patients. Methods. This study was conducted on 60 patients admitted to Tanta University Hospital, Egypt, suffering from recurrent hepatic hydrothorax. The site of pigtail catheter insertion was determined by ultrasound guidance under complete aseptic measures and proper local anesthesia. Insertion was done by pushing the trocar and catheter until reaching the pleural cavity and then the trocar was withdrawn gradually while inserting the catheter which was then connected to a collecting bag via a triple way valve. Results. The use of pigtail catheter was successful in pleural drainage in 48 (80% patients with hepatic hydrothorax. Complications were few and included pain at the site of insertion in 12 (20% patients, blockage of the catheter in only 2 (3.3% patients, and rapid reaccumulation of fluid in 12 (20% patients. Pleurodesis was performed on 38 patients with no recurrence of fluid within three months of observation. Conclusions. Pigtail catheter insertion is a practical method for treatment of recurrent hepatic hydrothorax with a low rate of complications. This trial is registered with ClinicalTrials.gov Identifier: NCT02119169.

    Occult hepatitis B viral infection is the presence of hepatitis B viral nucleic acids in the serum and/or liver in the absence of hepatitis B surface antigen. The study aimed to determine the prevalence of occult hepatitis B virus infection among hepatitis C virus-negative hemodialysis patients and to identify their genotypes. of 144 patients on maintenance hemodialysis, 50 hepatitis B surface antigen and hepatitis C virus nucleic acid-negative patients were selected according to strict inclusion criteria to avoid the effect of confounding variables. The following investigations were done: serum AST and ALT; HBsAg; HBcAb; HCV-Ab; HCV-RNA; and HBV-DNA. Positive hepatitis B viral nucleic acid was confirmed in 12/144 (8.3%) hemodialysis patients and 12/50 (24%) in our study group (occult infection). Mean hemodialysis periods for negative patients and occult hepatitis B virus patients were 27.3±18.8 and 38.4±8.14 months, respectively, and this difference was significant (p-value=0.02). Mean alanine transaminase levels were 20.27±5.5IU/L and 25.3±9.6 in negative patients and occult infection patients, respectively. This difference was non-significant. Aspartate transaminase levels were 21.4±10.2IU/L and 27.3±4.6IU/L, respectively, in negative patients and infected patients; this difference was significant (p-value=0.03). Half (6/12) of the positive samples belonged to genotype 'B', 33.3% (4/12) to 'C', and 16.6% (2/12) to genotype 'D'. OBI is likely among hemodialysis patients even without HCV coinfection (24%). Genotype D cannot be the only genotype distributed in Upper Egypt, as the current study reported relatively new results that 50% of the patients with occult B carry genotype B, 33.3% carry genotype C and only 16.6% carry genotype D.

There are limited data about the prevalence of occult HBV infection in patients on long-term hemodialysis. Occult HBV is defined as positive HBV DNA in the blood in the absence of hepatitis B surface ­antigen in the serum. In this study, we determined the prevalence of occult HBV in hemodialysis patients with or without HCV infection. The study included 116 patients with end-stage renal disease on chronic hemodialysis, of whom 64 patients were HCV RNA positive (Group 1, and 52 were HCV RNA negative (Group 2. We found that four of 64 (6.3% hemodialysis patients with HCV infection (Group 1 had occult HBV, while only two of 52 (3.8% hemodialysis patients without HCV (Group 2 had occult HBV. We then examined whether gender-matched ­hemodialysis patients with positive HBV DNA in the two hemodialysis groups differed in specific parameters, ie, age, degree of liver dysfunction, and presence of ­coinfection with schistosomiasis, a common parasitic infection of the liver. We found no significant difference between the groups having positive HBV DNA with regard to serum levels of liver enzymes, aspartate transaminase, albumin, and hepatitis B core antigen (P > 0.05. However, we detected significantly higher levels of alanine transaminase, a prolonged duration of hemodialysis, and higher levels of schistosomal antibodies in Group 1 than in Group 2. Interestingly, we found that the presence of schistosomal

    AIM To investigate the clinical utility of serum annexin A2 (ANXA2) as a diagnostic marker for early hepatocellular carcinoma (HCC). METHODS This study was performed in HCC Clinic of Ain Shams University Hospitals, Cairo, Egypt and included: Group 1: Fifty patients with early stage HCC (Barcelona Clinic Liver Cancer stage A); Group 2: Twenty five patients with chronic liver disease; and Control Group: Fifteen healthy, age- and sex-matched subjects who were seronegative for viral hepatitis markers. The following laboratory investigations were done: Viral hepatitis markers [hepatitis B surface antigen and hepatitis C virus (HCV) antibodies], HCV RNA in HCV antibody-positive patients, serum alpha fetoprotein (AFP), and serum ANXA2 levels. RESULTS In this study, 88% of HCC patients (n = 44) were HCV-positive, while HBV infection represented only 8% of all HCC patients (n = 4); and two patients were negative for both viral markers. A highly significant difference was found between patients with HCC and chronic liver disease as well as controls with regard to serum ANXA2 levels (130, IQR 15-240; 15, IQR 15-17; and 17, IQR 15-30 ng/mL, respectively). The area under the curve of ANXA2 was 0.865; the cut-off value was established to be 18 ng/mL with a diagnostic sensitivity of 74% and a specificity of 88%, while the sensitivity and specificity of AFP at the cut-off value of 200 ng/dL were 20% and 100%, respectively. CONCLUSION Serum ANXA2 may serve as a biomarker for the early detection of HCC.

    To reduce the morbidity and mortality related to bacterial meningitis, it is important to discriminate bacterial meningitis from aseptic meningitis during the acute phase of the disease, when the clinical symptoms are often similar. To test the reliability of serum procalcitonin (PCT) to discriminate bacterial meningitis from aseptic meningitis in patients who have a negative direct cerebrospinal fluid (CSF) examination, and to evaluate the role of serum PCT to assess treatment efficacy compared with the total leukocyte count (TLC), erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). Forty patients with suspected acute meningitis and negative gram stains were included, and ten healthy persons were included as controls. According to the clinical examination and the CSF cytochemical analysis and cultures, the patients were divided into bacterial and aseptic groups. The measurements of serum PCT, ESR, CRP and TLC were performed. Patients in the bacterial group had a higher value of serum PCT at admission and at 3 days post-treatment than those in the aseptic group, with a highly significant difference between them. Serum PCT and, to a lesser extent, TLC had prognostic value in patients with acute meningitis, and PCT is more useful because it can be frequently measured for the diagnosis and follow-up of bacterial meningitis.

    Keeping an updated registry of bleeding disorders is crucial for planning care and documenting prevalence. We aimed to assess the prevalence of various bleeding disorders including rare inherited coagulation and platelet disorders concerning their clinico-epidemiological, diagnostic data and bleeding manifestations severity. Patients suffering from manifestations of bleeding or coagulation disorders presented to Hematology Clinic during 16 years were included and prospectively followed up. Demographics, clinical characteristics, complete blood count, bleeding, prothrombin and activated partial thromboplastin times, platelet aggregation tests and bone marrow aspiration were recorded. Overall 687 patients with bleeding disorders from total 2949 patients were identified. Inherited coagulation defects were found in 27.2%; hemophilia A (70.6%), hemophilia B (13.9%), factor I deficiency (2.3%), factor V deficiency (1.6%), factor X deficiency (4.2%), factor VII deficiency (2.6%), factor XIII deficiency (1.1%), combined factor deficiency (2.1%) and unclassified coagulation disorders in 1.6% of studied patients. Overall 72.7% had diagnosed with platelet disorders; immune thrombocytopenia was the commonest (74.8%), and inherited conditions represent (25.2%) in the following order: Glanzman's thrombasthenia (11.2%), von Willebrand disease (6.6%), Bernard-Soulier syndrome (1%) and Chediak Higashi in 0.4% and unclassified in 6%. Median age of diagnosis of coagulation and platelet disorders were 33 and 72 months. Presenting symptoms of coagulation disorders were: 25.1% post circumcision bleeding, 22.5% ecchymosis, 20.9% hemoarthrosis and 15% epistaxis. Symptoms of rare coagulation disorders were postcircumcision bleeding (20%), bleeding umbilical stump (20%), epistaxis (12%), hemoarthrosis (8%) and hematomas (4%). Presenting symptoms in rare inherited platelet disorders were purpura, ecchymosis, epistaxis and bleeding gums, respectively. Analysis of the clinico

    Full Text Available Background/Aim: Both nonalcoholic fatty liver disease (NAFLD and chronic hepatitis C virus (HCV infection are common in Egypt, and their coexistence is expected. There is controversy regarding the influence of NAFLD on chronic HCV disease progression. This study evaluates the effect of NAFLD on the severity of chronic hepatitis C (CHC (necroinflammation and fibrosis and assesses the relative contribution of insulin resistance syndrome to the occurrence of NAFLD in patients with chronic HCV infection. Patients and Methods: Untreated consecutive adults with chronic HCV infection admitted for liver biopsy were included in this study. Before liver biopsy, a questionnaire for risk factors was completed prospectively, and a blood sample was obtained for laboratory analysis. Results: Our study included 92 male patients. Their mean ± SD age and aspartate aminotransferase (AST level were 42 ± 7.7 years (range 20-56 and 68 ± 41.7 U/L (range 16-214, respectively. The mean insulin level and insulin resistance index were 15.6 ± 18.3 mIU/mL (range 5.1-137.4 and 5.9 ± 15.2 (range 0.9-136.2, respectively. Fifty four percent of patients had steatosis and 65% had fibrosis. In multivariate analyses, steatosis was associated with insulin resistance and fibrosis was associated with high AST level, age ≥40 years, and steatosis. Conclusions: Steatosis is a histopathologic feature in >50% of patients with chronic HCV infection. Insulin resistance has an important role in the pathogenesis of steatosis, which represents a significant determinant of fibrosis together with high serum AST level and older age.

    It is well known that hepatocellular carcinoma (HCC) develops as a consequence of hepatic fibrosis progression. In this study, we aimed to evaluate the inflammatory and fibrosis markers as predictors for HCC development among patients with hepatitis C virus (HCV) related chronic liver disease to help in early diagnosis and management of HCC. A total of 280 patients with chronic liver disease were included in this retrospective study, out of them 140 had liver cirrhosis with HCC and 140 had cirrhosis without HCC. Eight readily available blood indices King score, Fibro Q, AST-ALT ratio (AAR), APRI, LOK index, Goteborg University Cirrhosis Index (GUCI), fibro alpha, and Biotechnology Research Center (BRC) were constructed to compare the accuracies of these non invasive scores in predicting HCC development. All fibrosis scores except APRI were significantly higher in HCC. We found that Fibro alpha and BRC had superior diagnostic performance in prediction of HCC based on area under curve of 0.91 and 0.93, respectively compared to other scores with area under curve ranged from poor to failure (0.59-0.66). Almost all cirrhotic cases were secondary to HCV (93.6%), while HBV was detected in 2.1% of cases only. Anti-HCV positive was reported in 100% of HCC cases (P = 0.002). Fibro alpha and BRC scores can be used for prediction of HCC. J. Med. Virol. © 2016 Wiley Periodicals, Inc.

    Full Text Available Identification of risk factors of acute hepatitis C virus (HCV infection in Egypt is crucial for developing appropriate prevention strategies. There are few community-based studies on the epidemiology and risk factors of hepatitis C infection in Egypt, which could not provide enough information. Clear identification of past and current risk factors for infection is of utmost importance so that intervention programs can be appropriately focused. This study aims to provide up-to-date information about changes in the incidence of individual risk factors for HCV infection transmission in Egypt.A total of 396 chronic HCV patients on follow-up treatment at liver center in El-Qabbary General Hospital in Alexandria were evaluated retrospectively regarding the potential iatrogenic, community acquired and behavioral HCV risk factors. Risk factors for HCV transmission were found in all study populations.At least three identifiable risk factors were reported by each participant. Some behavioral and community-acquired exposures that entail several risky behaviors particularly, unsafe sexual practices were exclusively established among males. We report a significant decline in prevalence of HCV transmission through blood transfusion, parenteral treatment, hospitalization, surgery, non medicalized circumcision, Hijiama done by informal practitioner, tattooing, folk body piercing and threading, sharing hygiene and sharp items, and the use of communal barber or manicure sets among younger age cluster.The pattern of risk differed among older patients compared to younger age group suggesting improved medical care and infection control measures and raised public health awareness regarding the different modes of viral transmission.

    Full Text Available AIM: Aim of this study was to examine the effectiveness of body acupuncture on body weight loss, routine laboratory tests and pro-inflammatory markers. METHODOLOGY: The study was performed on eighty obese patients. They were divided into three groups according to their body mass index. Subjects received acupuncture for three- six months in combination with a low-calorie diet. They were assessed pre and post acupuncture, by anthropometric measurement, routine laboratory tests and, tumor necrosis factor- alpha (TNF-α, interleukin- 6 (IL-6, and high sensitivity C-reactive protein (hsCRP levels in serum. RESULTS: The pre-acupuncture results showed significant difference between the three grades of obesity and the controls regarding TNFα, IL-6 and hsCRP. We found significant reduction in anthropometric measurement of adiposity after acupuncture. In comparing the pre &post acupuncture results of TNF-α, IL-6 and hsCRP showed high significant reduction after acupuncture. There are highly significant decrease in kidney function (creatinine and uric acid and lipid profile (cholesterol and triglycerides and fasting blood glucose, but there was no significant difference in urea, SGPT, SGOT, HDL and LDL. CONCLUSION: Body acupuncture in combination with diet restriction was found to be effective for weight loss and also reduction of the inflammatory reactions. Acupuncture could be used as a synergistic treatment option for obesity control.

    Among patients with chronic liver disease, impairment in HRQOL has been reported. Hepatocellular carcinoma (HCC) is one of the major squeal of chronic liver diseases. So, relationship between subjective HRQOL and HCC must be analysed. This study assessed the effect of HCC on HRQOL, and its loco-regional treatment on HRQOL. Forty patients with HCV related chronic liver disease as a control group was enrolled in the study. Eighty HCC patients on top of chronic HCV liver disease categorized according to the modality of loco-regional treatment (BCLC staging system) into GI; 40 HCC patients treated with radiofrequency ablation (RFA) and GII; 40 HCC patients treated with trans-arterial chemoembolization (TACE). The SF-36 questionnaire was performed before and one month after the intervention. Comparing the parameters of HRQOL in GI before and after RFA, and in GII before and after TACE; there was a statistically significant improvement in group I. However, the improvement in group II (TACE) was non-significant (P>0.05).

    Full Text Available Background: Phyllodes tumors are group of biphasic fibroepithelial tumors of the breast of varying malignant potential, ranging from benign tumors to fully malignant sarcomas. According to the Egyptian National Cancer Institute, female malignant cases showed appreciable increase in the recent time period for breast cancer with the malignant phyllodes tumors representing 0.41% of cases in the year 2003-2004. Aims: This is an immunohistochemical study to compare CD10 expression in benign, borderline, and malignant phyllodes tumors, in order to highlight its diagnostic and prognostic values. Materials and Methods: This study conducted 34 Egyptian female cases of phyllodes tumors of different grades to be studied histologically and immunohistochemically using antibodies against CD10. Statistical Analysis: The Chi-square test was used to determine differences in CD10 expression between benign, borderline, and malignant tumors. One-way ANOVA test was used to determine whether the difference was significant. Significance was established at P<0.05. Results: In the 24 cases of benign phyllodes tumors, only four cases (16.7% showed positive CD10 reactivity. Three cases (60% out of five borderline phyllodes tumors showed positive CD10 reactivity, while four (80% out of five cases of malignant phyllodes tumors showed positive CD10 staining. Conclusion: From these highly significant results, we believe that there is a strong correlation between CD10 expression and tumor grade, which could be an important observation that may have both diagnostic and prognostic implications as well as promising potential target for development of novel therapies.

    2013-12-01

    Full Text Available The One of the most challenging problems that encounter the Egyptian society is the lack of significant health care in the rural areas. This problem leads to more severe problems that face the society; the patients from the different rural areas needs to travel to the Egyptian capital where the most experienced physicians are available. This will make overhead not only on the patient budget but on the country budget since the focus on the capital makes a severe traffic problem which threaten most of the economic sectors. The telemedicine is considered one of the most important solutions that could mitigate the accumulated problems of lack of experienced physicians in the Egyptian rural areas. The application of the telemedicine encounters several challenges in Egypt; the lack in the experience in dealing with the telemedicine in these areas and the problem of insufficient medical experts that could fulfil the gab. In this paper, a new ICT-based telemedicine system is proposed to serve the Egyptian society. The portal is already released and snapshots are included

    2017-01-01

    Purpose Conivaptan is an intravenous dual V1A/V2 vasopressin antagonist approved for the treatment of euvolemic and hypervolemic hyponatremia. Earlier studies showed that patients with moderate liver disease could be safely treated with conivaptan by reducing the dose by 50%, whereas patients with mild hepatic impairment needed no dose adjustment. The objective of this Phase 1, open-label study was to assess the pharmacokinetics, protein binding, and safety of 48 h of conivaptan infusion in individuals with severe hepatic impairment. Patients and methods Eight subjects with severe hepatic impairment (Child–Pugh score 10–15) and nine subjects with normal liver function were enrolled. Intravenous conivaptan (20 mg) was given as a 30 min loading dose on Day 1 followed by two consecutive 20 mg continuous infusions over 24 h each. Subjects were monitored for adverse events and changes in clinical laboratory parameters. Plasma and urine pharmacokinetic samples were collected at defined times. Subjects were followed through Study Day 5. Results Hepatically impaired individuals exhibited higher concentrations of plasma conivaptan throughout the treatment period. Overall exposure, as measured by area under the plasma conivaptan concentration-time curve from time zero through infinity (AUCINF), was ~60% higher in impaired individuals compared to those with normal liver function. Terminal elimination half-life was slightly longer in impaired subjects (12 h) as compared to normal subjects (9 h), and clearance was 65% higher in subjects with normal liver function, while urinary excretion was higher in impaired individuals. Albumin levels directly, and alkaline phosphatase inversely, correlated with conivaptan clearance. Conclusion A 20 mg conivaptan loading dose given >30 min followed by two daily infusions of 20 mg each was well tolerated by patients with severe hepatic impairment as monitored by adverse events and clinical laboratory values. Based on pharmacokinetic data

    To evaluate the frequency of single-nucleotide polymorphism at the -88 myxovirus resistance (MxA) gene promoter region in relation to the status of hepatitis C virus (HCV) progression and response to combined interferon (IFN) in chronic HCV Egyptian patients. One hundred ten subjects were enrolled in the study; 60 HCV genotype 4-infected patients who underwent combined IFN therapy and 50 healthy individuals. All subjects were genotyped for -88 MxA polymorphism by the restriction fragment length polymorphism technique. There was an increasing trend of response to combined IFN treatment as 34.9% of GG, 64.3% of GT, and 66.7% of TT genotypes were sustained responders (P=0.05). The T allele was significantly affecting the response rate more than G allele (P=0.032). Moreover, the hepatic fibrosis score and hepatitis activity were higher in GG genotypes compared with the GT and TT genotypes. The multivariate analysis showed that the MxA GG genotype was an independent factor increasing the no response to IFN therapy (P=0.04, odds ratio [OR] 3.822, 95% confidence interval [CI] 1.056-11.092), also MxA G allele (P=0.0372, OR 2.905, 95% CI 1.066-7.919). MxA -88 polymorphism might be a potential biomarker to predict response to IFN and disease progression in chronic HCV-infected patients.

    Toll-like receptors (TLRs) are recognized as fundamental contributors to the immune system function against infections. Hepatitis C virus (HCV) infection represents a global health problem especially in Egypt having the highest HCV prevalence worldwide where HCV infection is a continuing epidemic. The aim of the present study was to investigate the possible association between genetic variation in TLR-3 and TLR-9 and HCV infection and hepatic fibrosis in chronic HCV-positive Egyptian patients. The present study included 100 naïve chronic HCV-positive patients and 100 age- and sex-matched healthy controls. Genotyping of TLR-3 (_7 C/A [rs3775296]), TLR-3 (c.1377C/T [rs3775290]) and TLR-9 (1237T/C [rs5743836]) were done by polymerase chain reaction restriction fragment length polymorphism technique. Frequency of polymorphic genotypes in TLR-3 (_7 C/A), TLR-3 (c.1377C/T) and TLR-9 (1237T/C) were not significantly different between studied HCV-positive patients and controls with P values 0.121, 0.112, and 0.683, respectively. TLR-3 c.1377 T-allele was associated with advanced stage of hepatic fibrosis (P = 0.003).

    Objective To study the relationships between cognitive impairment in patients with lacunar infarcts and quantitative CT measures and to determine the independent correlative factors of cognitive impairment. Methods Neuropsychological examination was conducted for 128 patients with acute lacunar infarct. Number, location, and volume of infarcts, cerebral atrophy index and severity of white matter lesions (WMLs) were measured and recorded. Results The number of lacunar infarcts in cognitive impairment (CI) group was significantly larger than that in cognitive normal (CN) group. Mean width of sulcus and sylvian fissure, index of frontal horn and ventricular-brain ratio (VBR) were significantly different in both groups. There were more patients with 3 grades or 4 grades WMLs in CI group (62%) than those in CN group (22%). The total volume of lacunar infarcts showed no statistically significant difference. Logistic regression analysis indicated that the number of lacunar infarcts in frontal subcortex and thalamus, the volume of infarcts in anterior periventricular white matter, width of cerebral sulcus and sylvian fissure were correlated with cognitive impairment respectively. Additionally, age and education were correlative factors of cognitive impairment in patients with lacunar infarct. Conclusion Correlative factors of cognitive impairment in patients with lacunar infarct are not merely one feature, but a combination of infarct features (number, location, and volume), cortical atrophy and host factors (age and education).

    To describe the characteristics and associated factors of Alzheimer disease (AD) patients with balance and gait impairments. Balance and gait impairments were assessed in 380 AD patients using the Tinetti test. A total of 120 (31.5%) patients had an abnormal Tinetti test, 96 (25.2%) had balance impairments, and 72 (18.9%) patients presented gait impairments. Global Tinetti score was associated with age [odds ratio (OR), 1.09; 95% confidence interval (CI), 1.05-1.14], Mini-Mental State Examination (MMSE) score (OR, 0.94; 95% CI, 0.90-0.99), activities of daily living (ADL) score (OR, 0.62; 95% CI, 0.47-0.83), and being man (OR, 0.44; 95% CI, 0.25-0.78). Balance impairment was associated with age (OR, 1.11; 95% CI, 1.05-1.17), ADL score (OR, 0.60; 95% CI, 0.43-0.84), and being female (OR, 0.19; 95% CI, 0.08-0.49). Gait impairment was associated with age (OR, 1.09; 95% CI, 1.03-1.15), MMSE score (OR, 0.92; 95% CI, 0.87-0.98), ADL score (OR, 0.63; 95% CI, 0.46-0.87), body mass index (OR, 1.10; 95% CI, 1.01-1.18), presence of comorbidities (OR, 2.13; 95% CI, 1.14-3.96), and the Cornell score (OR, 2.97; 95% CI, 1.12-7.89). AD patients are frequently concerned with balance and gait impairments. These impairments were associated to factors related to the severity of the disease (low MMSE and low ADL); nonmodifiable factors such as age or sex; and modifiable factors such as depression, obesity, and presence of comorbidities.

    Sickle cell disease (SCD) complications are associated with oxidative stress. Glutathione S-transferases (GSTs) are a group of enzymes that protect against oxidative stress. The aims of this study was to evaluate the prevalence of GSTM1, GSTT1, and GSTP1 gene polymorphisms among homozygous sickle cell anemia patients and to investigate the possible association between the presence of these polymorphisms and SCD severity and complications. Genotyping the polymorphisms in GSTT1 and GSTM1 genes was performed using the multiplex polymerase chain reaction (PCR) method. The GSTP1 ILe105Val polymorphism was determined using PCR-restriction fragment length polymorphism. GSTM1 null genotype was significantly associated with increased risk of severe vaso-occlusive crises (VOC) (odds ratio  =  1.52, 95% confidence interval  =  0.42-5.56, P  =  0.005). We found no significant association between GST genotypes and frequency of sickle cell-related pain, transfusion frequency, disease severity, or hydroxyurea treatment. GSTM1 gene polymorphism may be associated with risk of severe VOC among Egyptian SCD patients.

    Self-narratives of patients have received increasing interest in schizophrenia since they offer unique material to study patients' subjective experience related to their illness, in particular the alteration of self that accompanies schizophrenia. In this study, we investigated the life narratives and the ability to integrate and bind memories of personal events into a coherent narrative in 27 patients with schizophrenia and 26 controls. Four aspects of life narratives were analyzed: coherence with cultural concept of biography, temporal coherence, causal-motivational coherence and thematic coherence. Results showed that in patients cultural biographical knowledge is preserved, whereas temporal coherence is partially impaired. Furthermore, causal-motivational and thematic coherence are significantly impaired: patients have difficulties explaining how events have modeled their identity, and integrating different events along thematic lines. Impairment of global causal-motivational and thematic coherence was significantly correlated with patients' executive dysfunction, suggesting that cognitive impairment observed in patients could affect their ability to construct a coherent narrative of their life by binding important events to their self. This study provides new understanding of the cognitive deficits underlying self-disorders in patients with schizophrenia. Our findings suggest the potential usefulness of developing new therapeutic interventions to improve autobiographical reasoning skills.

    Full Text Available Nitric oxide (NO, a recently discovered free radical, is overproduced in liver cirrhosis. Hepatitis C virus (HCV might increase NO levels via increased inducible NO synthase (iNOS. This work was carried out to study the effect of HCV-induced liver cirrhosis on NO levels among Egyptian patients. The study included 46 patients with liver cirrhosis, and 30 healthy individuals of matched age and sex. NO levels determined as the stable endproduct nitrate, showed a statistically significant increase among patients compared to the control group (P < 0.001. Furthermore, NO levels increased proportionally with the severity of liver cirrhosis as assessed by Child’s classification (P < 0.05. Moreover, schistosomial infection enhanced NO levels in cirrhotic patients with HCV infection compared to non-bilharzial patients (P < 0.001. Polymerase chain reaction (PCR and branched DNA assays were used for detection of HCV RNA positivity, and measurement of the virus load, respectively. Both showed a positive correlation with the NO levels (P < 0.001. At a nitrate cutoff value of 70 μmol/L, the sensitivity and specificity were 83.0% and 37.0% respectively. Chi square analysis showed a significant correlation between ALT levels and both HCV RNA positivity by polymerase chain reaction (PCR (P < 0.02, and virus load (P < 0.05. Interestingly enough, there was a significant positive correlation between HCV RNA and schistosomal antibody titer as measured by hemaglutination inhibition assay (HAI (P < 0.05. The data presented in this report indicated an association between NO levels and the development and progression of liver cirrhosis. Furthermore, the findings obtained from this study demonstrated that schistomiasis is an important risk factor involved in enhancement of NO levels and virus replication. The latter may aggravate liver cell injury and hence the development of cirrhosis.

    Full Text Available INTRODUCTION: Sickle cell anemia and thalassemia result in impaired bone health in both adults and youths. Children with other types of chronic hemolytic anemia may also display impaired bone health. STUDY DESIGN: To assess bone health in pediatric patients with chronic hemolytic anemia, a cross-sectional study was conducted involving 45 patients with different forms of hemolytic anemia (i.e., 17 homozygous sickle cell disease and 14 hereditary spherocytosis patients. Biochemical, radiographic and anamnestic parameters of bone health were assessed. RESULTS: Vitamin D deficiency with 25 OH-vitamin D serum levels below 20 ng/ml was a common finding (80.5% in this cohort. Bone pain was present in 31% of patients. Analysis of RANKL, osteoprotegerin (OPG and osteocalcin levels indicated an alteration in bone modeling with significantly elevated RANKL/OPG ratios (control: 0.08+0.07; patients: 0.26+0.2, P = 0.0007. Osteocalcin levels were found to be lower in patients compared with healthy controls (68.5+39.0 ng/ml vs. 118.0+36.6 ng/ml, P = 0.0001. Multiple stepwise regression analysis revealed a significant (P<0.025 influence of LDH (partial r2 = 0.29, diagnosis of hemolytic anemia (partial r2 = 0.05 and age (partial r2 = 0.03 on osteocalcin levels. Patients with homozygous sickle cell anemia were more frequently and more severely affected by impaired bone health than patients with hereditary spherocytosis. CONCLUSION: Bone health is impaired in pediatric patients with hemolytic anemia. In addition to endocrine alterations, an imbalance in the RANKL/OPG system and low levels of osteocalcin may contribute to this impairment.

    Attention disorders are common symptoms in patients with untreated hyperthyroidism. Nevertheless, it is unknown whether they represent a global attention deficit or selective impairment of attention networks. Thirty-seven patients with hyperthyroidism were recruited and underwent the Attention Network Test (ANT), which provided measures of three independent attention networks (alerting, orienting and executive control), before being treated with methimazole. This study demonstrated that patients with untreated hyperthyroidism had significant deficits in the alerting and executive control networks. Interestingly, a significant positive association was also found between T4 level and the value of the executive network in patients with hyperthyroidism. These results suggest that the patients with hyperthyroidism may not just exist a specific impairment of attention networks, and there was some relationship between the level of T4, not T3 or TSH, and the value of the executive control network in patients with hyperthyroidism.

    A hallmark of negative symptoms in schizophrenia is reduced motivation and goal directed behavior. While preclinical models suggest that blunted striatal dopamine levels can produce such reductions, this mechanism is inconsistent with evidence for enhanced striatal dopamine levels in schizophrenia. In seeking to reconcile this discrepancy, one possibility is that negative symptoms reflect a failure of striatal motivational systems to mobilize appropriately in response to reward-related information. In the present study, we used a laboratory effort-based decision-making task in a sample of patients with schizophrenia and healthy controls to examine allocation of effort in exchange for varying levels of monetary reward. We found that patients and controls did not differ in the overall amount of effort expenditure, but patients made significantly less optimal choices in terms of maximizing rewards. These results provide further evidence for a selective deficit in the ability of schizophrenia patients to utilize environmental cues to guide reward-seeking behavior. Copyright © 2014 Elsevier B.V.

    To investigate the role of perceived neighborhood characteristics, socioeconomic status (SES) and rural residency in influencing the health status outcome of Egyptian patients with systemic lupus erythematosus (SLE). Eighty patients affected with SLE were consecutively included in this a single-center cross-sectional study from July, 2011 to July, 2013. Outcome measures included the Systemic Lupus Activity Questionnaire (SLAQ) score, the Medical Outcomes Study Short Form-36 Health Survey physical functioning score and Center for Epidemiologic Studies-Depression (CES-D score of ≥ 19 points). Multivariate logistic regression analyses were conducted. Results from multivariate logistic regression analyses, a separate adjusted model of each perceived neighborhood characteristic, indicate associations of worse perceived social cohesion with higher SLAQ scores (P < 0.01) and associations of worse perceived neighborhood aesthetics and safety with lower SF-36 physical functioning scores after adjusting for covariates (P < 0.01). Regarding the association of socioeconomic status and rural residency with health status outcomes, the results found association of poor socioeconomic status with the three health status outcome measures and association between rural residency and depression symptoms. Individuals had increased odds of depressive symptoms if they perceived worse neighborhood social cohesion (odds ratio [OR]: 2.14; CI: 1.42-2.80), if they perceived worse neighborhood safety (OR: 1.64; CI: 1.02-2.40) and if they perceived worse neighborhood aesthetic characteristics (OR: 2.79; CI: 1.84-3.38). Study findings indicate that poor socioeconomic status, rural residency and perceived neighborhood characteristics are associated with depression; worse perceived neighborhood aesthetics and safety are associated with lower SF-36 physical functioning, and worse neighborhood social cohesion is associated with higher disease activity among patients with SLE. © 2014 Asia

    Full Text Available Chronic obstructive pulmonary disease (COPD is a respiratory disease that results in progressive airflow limitation and respiratory distress. Physiopathological features of COPD suggest that people who suffer from this disease have many risk factors for falls that have been identified in older individuals. The aim of the study was to compare and quantify functional balance between COPD patients and healthy subjects; to investigate the risk of falls in acute stages of the disease and to identify risk factors that could lead to falls.We studied 46 patients with moderate-severe COPD (29 stable and 17 in acute exacerbation--AECOPD and 17 healthy subjects (control group having similar demographic data. We analyzed the difference in Berg Balance Scale (BBS, Single Leg Stance (SLS and Timed Up and Go test (TUG between these three groups and the correlation of these scores with a number of incriminatory factors.The presence of COPD was associated with significant worsening of balance tests: BBS (55 control, vs. 53 COPD, vs. 44 AECOPD points p<0.001, TUG (8.6 control vs. 12.3 COPD vs. 15.9 AECOPD seconds. p<0.001, SLS (31.1 control vs. 17.7 COPD vs. 7.2 AECOPD seconds p<0.001 which may be associated with an increased risk of falls. Anxiety and depression were significantly associated with decreased balance test scores; anxiety (2 control vs. 6 COPD vs. 9 AECOPD points p<0.001 depression (2 control vs. 7 COPD vs. 12 AECOPD points p<0.001.According to our results COPD patients in moderate-severe stages and especially those in exacerbation have a high risk of falls.

    2015-01-01

    Full Text Available Diffuse large B-cell lymphoma (DLBCL is the most common type of lymphomas worldwide. The pathogenesis of lymphomas is not yet well understood. SV40 induces malignant transformation by the large T-antigen (L-TAG and promotes transformation by binding and inactivating p53 and pRb. L-TAG can bind pRb promoting the activation of the E2F1 transcription factor, thus inducing the expression of genes required for the entry to the S phase and leading to cell transformation. This immunohistochemical study was conducted to assess the prognostic role and relationship of SV40 L-TAG and E2F1 in diffuse large B-cell lymphoma (DLBCL of Egyptian patients. This retrospective study was conducted on 105 tissue specimens including 20 follicular hyperplasia and 85 DLBCL cases. SV40 L-TAG was identified in 3/85 (4% of DLBCL. High Ki-67 labeling index (Ki-67 LI and apoptotic count were associated with high E2F1 expression (p<0.001 for all. No significant association was reached between E2F1 and SV40. E2F1 expression proved to be the most and first independent prognostic factor on overall survival of DLBCL patients (HR = 5.79, 95% CI = 2.3–14.6, and p<0.001. Upregulation of E2F1 has been implicated in oncogenesis, prognosis, and prediction of therapeutic response but is not seemingly to have a relationship with the accused SV40.

    A single-nucleotide polymorphism (SNP) in the interleukin (IL)-28B gene was used as a major predictor of the response to treatment in patients with hepatitis C virus (HCV) infection. Data examining the role of IL-10 and IL-18 gene polymorphisms among HCV genotype 4 (G4)-infected Egyptians in response to pegylated interferon (PEG-IFN) plus ribavirin (RBV) therapy are limited. This study investigated the impact of SNP at IL-10.rs1800896 (at position -1082) and IL-18.rs1946518 genes (at position -607) on the response to PEG-IFN/RBV therapy in HCV-infected Egyptians. This study was carried out on 100 HCV patients treated with PEG-IFN plus RBV and 100 healthy controls. The HCV patients included 50 treatment non-responders (NR) and 50 subjects with sustained virologic response (SVR). Genomic DNA from venous blood of subjects was extracted and IL-10.rs1800896 and IL-18.rs1946518 genotypes were determined using allele-specific amplification and SYBR Green real-time PCR. Linkage disequilibrium between the two SNPs was estimated using Haploview software. The frequency of the IL-10.rs1800896 AA, AG and GG genotypes among non-responders were 16 %, 70 % and 14 % while among SVR subjects, the frequency was 34 %, 60 % and 6 %, respectively (p=0.073). On the other hand, the frequency of the IL-18.rs1946518 AA, AC and CC genotypes among non-responders was 14 %, 50 % and 36 %, respectively, while among responders, these frequencies were 28 %, 44 % and 28 %, (p = 0.220). Both markers were in linkage equilibrium (D' = 0.23; r (2) = 0.052). SNPs in the IL-10.rs1800896 and IL-18.rs1946518 genes could not predict the outcome of HCV infection in Egyptians treated with PEG-IFN/RBV.

    Daptomycin is a lipopeptide bactericidal antimicrobial indicated in the treatment of skin and soft tissue infections (SSTI), Staphylococcus aureus-related right-sided infective endocarditis (RIE) and bacteremia secondary to these infections. The recommended dosage in patients with previous renal impairment is 4 mg/kg/48 hours in SSTI. There are no data published for SSTI and RIE followed by bacteremia. Based on pharmacokinetic models, the recommended dosage in patients under hemodialysis is 4 mg/kg after dialysis. The present article aims to review of the latest published data on daptomycin use in patients with renal impairment and to relate these findings to preliminary data from the EUCORE registry in Spain.

    Full Text Available Epstein-Barr virus (EBV plays a major role in liver pathology. Similar to other members of the herpesvirus family, EBV establishes a persistent infection in more than 90% of adults. The aim of this study was to evaluate the impact of EBV and chronic hepatitis C co-infection (HCV on biochemical and immunological responses in patients. The study was conducted in 62 patients and 33 apparently healthy controls. Patients were divided into three groups: group I, consisting of 31 patients with chronic hepatitis C infection (CHC, group II, consisting of eight patients with EBV infection and without HCV infection and group III, consisting of 23 patients with EBV and chronic HCV. The percentage of CD3+ cells, helper CD4+ cells and CD19+ B-cells was measured by flow cytometry. Human interferon-γ (IFN-γ and interleukin (IL-15 levels were measured by an ELISA. The levels of liver alanine aminotransferase and aspartate aminotransferase enzymes were higher in EBV/HCV patients compared to that in EBV and HCV mono-infected patients. EBV/HCV patients had significantly reduced percentages of CD3+ and CD4+ cells compared to EBV patients. Serum IFN-γ levels were significantly reduced in EBV/HCV patients (3.86 pg/mL compared to CHC patients (6.76 pg/mL and normal controls (4.69 pg/mL. A significant increase in serum IL-15 levels was observed in EBV/HCV patients (67.7 pg/mL compared to EBV patients (29.3 pg/mL. Taken together, these observations suggest that HCV and EBV co-infection can potentiate immune response dampening in patients.

    Parkinson's disease (PD) patients show marked impairments in processing action verbs, and to a lesser extent, concrete (specially, manipulable) nouns. However, it is still unclear to what extent deficits in each of these categories are influenced by more general cognitive dysfunctions, and whether they are modulated by the words' implied motility. To examine these issues, we evaluated 49 non-demented PD patients and 49 healthy volunteers in an oral production task. The patients were divided into two groups depending on the presence or absence of mild cognitive impairment (PD-MCI and PD-nMCI, respectively). Participants named pictures of actions varying in motion content (low and high) and of objects varying in manipulability (low and high). The PD-MCI group showed deficits across all four categories. However, PD-nMCI patients exhibited a selective difficulty for high-motion action verbs. This finding corroborates and refines previous results suggesting that disturbances of action-related lexico-semantic information in PD constitute a sui generis alteration manifested early in the course of the disease's physiopathology. Moreover, it suggests that the grounding of action verbs on motor circuits could depend on fine-grained intracategorical semantic distinctions.

    Circulating microRNAs are deregulated in liver fibrosis and hepatocellular carcinoma (HCC) and are candidate biomarkers. This study investigated the potential of serum microRNAs; miR-19a, miR-296, miR-130a, miR-195, miR-192, miR-34a, and miR-146a as early diagnostic biomarkers for hepatitis C virus (HCV)-related HCC. As how these microRNAs change during liver fibrosis progression is not clear, we explored their serum levels during fibrosis progression in HCV-associated chronic liver disease (CLD) and if they could serve as non-invasive biomarkers for fibrosis progression to HCC. 112 Egyptian HCV-HCC patients, 125 non-malignant HCV-CLD patients, and 42 healthy controls were included. CLD patients were subdivided according to Metavir fibrosis-scoring. Serum microRNAs were measured by qRT-PCR custom array. Serum microRNAs were deregulated in HCC versus controls, and except miR-130a, they were differentially expressed between HCC and CLD or late fibrosis (F3-F4) subgroup. Serum microRNAs were not significantly different between individual fibrosis-stages or between F1-F2 (early/moderate fibrosis) and F3-F4. Only miR-19a was significantly downregulated from liver fibrosis (F1-F3) to cirrhosis (F4) to HCC. Individual microRNAs discriminated HCC from controls, and except miR-130a, they distinguished HCC from CLD or F3-F4 patients by receiver-operating-characteristic analysis. Multivariate logistic analysis revealed a panel of four microRNAs (miR-19a, miR-195, miR-192, and miR-146a) with high diagnostic accuracy for HCC (AUC = 0.946). The microRNA panel also discriminated HCC from controls (AUC = 0.949), CLD (AUC = 0.945), and F3-F4 (AUC = 0.955). Studied microRNAs were positively correlated in HCC group. miR-19a and miR-34a were correlated with portal vein thrombosis and HCC staging scores, respectively. In conclusion, studied microRNAs, but not miR-130a, could serve as potential early biomarkers for HCC in high-risk groups, with miR-19a as a biomarker for liver fibrosis

    Although patients with schizophrenia exhibit autobiographical memory impairment, which is considered to be a limiting factor in their daily life, the mechanisms underlying such impairment have been rarely studied. In the current study, we investigate whether rumination and, in particular, brooding, which is a form of maladaptive repetitive thinking, may be linked to the difficulty that patients with schizophrenia experience when attempting to access specific autobiographical memories. Our results indicate that patients reported less specific autobiographical memories compared to control participants. Patients also displayed a higher level of brooding and had more depressive symptoms. According to the CaR-FA-X model (Williams et al., 2007), depression and brooding were associated with memory specificity in control participants. In contrast, neither depression nor brooding was correlated with memory specificity in patients. These results suggest that depression and rumination may not be directly related to patients' difficulty to recall specific memories and that other factors, such as metacognitive deficits, must first be considered when seeking interventions aimed to improve autobiographical memory in patients with schizophrenia.

    Until recently the measurement of pain in cognitively impaired patients represented a neglected field in the diagnostics and treatment of pain. Investigations indicate a prevalence of pain in nursing home residents of between 45 % and 80 %. This study investigated the reliability of the German translation of the Doloshort scale and compared it with the visual analog scale (VS). The aim of this study was to determine the practical applicability of this scale in the clinical routine and to calculate the intrarater reliability (retest) and interrater reliability. The interrater and intrarater reliability of the Doloshort scale was between 0.949 and 0.970. There was a highly significant correlation between the values of the Doloshort scale and the VAS. The Doloshort scale is a well suited measurement instrument for the evaluation of pain in cognitively impaired patients. Because of the short form only simple instructions are necessary and it has a high acceptance with users.

    Background/Aim: Among the various methods for evaluating gastric emptying, the real-time ultrasound is safe, does not require intubation, or rely on either radiologic or radionuclide technique. The aim of our work was to measure the gastric emptying in pediatric patients with portal hypertension by using the real-time ultrasound. Patients and Methods: Forty patients with portal hypertension with mean age 7 ± 2.8 years and 20 healthy children as a control group underwent gastric emptying study by using real-time ultrasound. The cross-sectional area of the gastric antrum was measured in the fasting state and then each subject was allowed to drink tap water then calculated by using formula area (π longitudinal × anteroposterior diameter/4). The intragastric volume was assumed to be directly proportional to the cross-sectional area of the antrum. Results: The mean gastric emptying half-time volume was significantly delayed in portal hypertension patients (40 ± 6.8 min) compared with the control subjects (27.1 ± 3.6) min (P<0.05). Patients with extrahepatic portal vein obstruction had significant delayed gastric emptying in comparison to patients with portal hypertension due to other etiologies (36.14 ± 4.9 vs 44.41 ± 6.04 min; P<0.01). Conclusion: Ultrasound is a noninvasive and a reliable method for measuring gastric emptying in pediatric patients. Gastric emptying was significantly delayed in patients with portal hypertension. Etiology of portal hypertension may influence gastric emptying time in patients with chronic liver disease. PMID:22249091

    Full Text Available Background/Aim: The immunopathogenesis of occult Hepatitis C virus (HCV infection is a matter of great controversy and has been suggested to involve a complex balance between cytokines with pro- and anti-inflammatory activity. This work aimed at studying the serum Th1 and Th2 cytokine production in patients with occult HCV infection. Materials and Methods: Serum levels of cytokines of Th1 (interleukin [IL]-2, INF-γ and Th2 (IL-4 were measured in 27 patients with occult HCV infection and 28 patients with chronic hepatitis C infection. Results: The levels of IL-2 and interferon-γ were highly significantly increased in patients with chronic HCV infection (P<0.001. IL-4 was highly significantly increased in occult HCV infection (P<0.001. Significant increases were noted in chronic HCV infection regarding bilirubin (P<0.001, ALT (P = 0.009, AST (P = 0.013, AFP (P<0.001, while serum albumin was significantly higher in occult HCV infection (P<0.001. Necroinflammation (P<0.001, fibrosis (P<0.001, and cirrhosis (P = 0.03 were significantly increased in chronic HCV infection. Conclusion: Our data revealed a high prevalence of occult HCV infection (25% in patients with unexplained persistently abnormal liver function test results. Those patients exhibited a distinct immunoregulatory cytokine pattern, favoring viral persistence and explaining the less aggressive course of this disease entity than chronic HCV infection.

    Full Text Available There is growing evidence showing that bipolar disorder is associated with persistent cognitive deficits. However, the exact meaning and impact of cognitive deficits in bipolar disorder is still not entirely known, even though they have been associated with poor psychosocial functioning. This study aims to summarize cognitive and psychosocial functioning findings of remitted bipolar patients. We conducted an extensive Medline search of the published English literature for the period January 2000– March 2014 using a variety of search terms to find relevant articles. Bibliographies of retrieved papers were further analysed for publications of interest. Our results showed that: (1 all mood states of bipolar disorder are associated with cognitive impairment. However, the euthymic state is associated with less impairment than the other states; (2 there is a strong association between clinical factors (i.e, duration of illness, number of episodes, residual mood symptoms, comorbidities and cognitive impairment in euthymic bipolar patients, although these factors do not account fully for these deficits; (3 cognitive deficits, in particular, verbal learning and executive dysfunctions may contribute to poor functioning. In conclusion, our review suggests that cognitive deficits are strongly associated with mood episodes; such deficits persist, in lower degree, during remission. Impairment on cognitive performance may explain, in part, poor long–term functioning in remitted bipolar patients. It highlights that psychosocial interventions in combination with pharmacotherapy should be considered to improve cognition and enhance the level of functioning. Therefore, studies assessing the efficacy of novel strategies focused on cognitive and functional status are an important area of future investigation in bipolar disorder.

    Rheumatoid arthritis (RA) differs depending on the age of disease onset. The differences between EORA and YORA are important because they have clinical and therapeutic implications. 1185 patients were ranked after classification according to age at onset of the disease into YORA I (16-40 years), YORA II (41-60 years) and EORA >60 years. All patients groups were compared, based on disease duration, disease activity, severity parameters and drug history. YORA I included 298 patients, 28.85% were males, with mean age of 29.4 ± 6 years and disease duration 4 ± 3.3 y, YORA II included 539 patients, 33.77% males, age 49.7 ± 6.1 y and disease duration 6.5 ± 5.6 y. EORA included 348 RA patients 40.5% males, age 67.1 ± 6.6 y, disease duration 9.95 ± 7.2 y. Activity was increased in EORA compared to YORA I and YORA II, while severity decreased in EORA. ESR, CRP and degree of anemia were higher in EORA. RF titer was higher in YORA. Small joints of the hands and feet were more involved in YORA, while, large joints in EORA. Rheumatoid nodules were increased in YORA I than EORA P = 0.04. Polymyalgia rheumatica was exclusively present in EORA group 25 patients 7.2%.

    Vernal kerato-conjunctivitis (VKC) is an infrequent but serious form of allergic conjunctivitis common in warm and humid areas where air is rich in allergens. It affects both eyes asymmetrically. Although VKC is a self-limiting disease but visions affecting corneal complications influence the quality of life in school children. The aim of this study was to list the corneal complications due to this condition and to find out the extent of visual impairment among VKC patients. This cross-sectional study was conducted in the department of Ophthalmology, Benazir Bhutto Shaheed Hospital on 290 eyes of diagnosed cases of VKC. The diagnosis of VKC was made on the basis of history and examination. Visual acuity was recorded using Snellen's notation and visual impairment was classified according to World Health Organization classification for visual disabilities. The mean age of presentation was 10.83±6.13 years. There were 207 (71.4%) males and 83 (28.6%) females. Corneal scarring was observed in 59 (20.3%) eyes. Keratoconus was found to be in 17 (5.9%) eyes. Shield ulcer was detected in 09 (3.1%) eyes while 07 (2.4%) eyes had corneal neovascularization. Majority of the patients with visual loss had corneal scarring and the complication that led to severe visual loss in most of the eyes was Keratoconus. Vernal kerato-conjunctivitis in the presence of corneal complications is a sight threatening disease and can lead to severe visual impairment.

    1α,25-Dihydroxyvitamin D3 upregulates the expression of the receptor activator of nuclear factor kB ligand (RANKL), and downregulates osteoprotegerin (OPG) expression. We tested the effects of polymorphisms in the vitamin D receptor gene (VDR), and OPG gene in rheumatoid arthritis (RA) patients and healthy controls and their relationship to bone mineral density (BMD) and development of osteoporosis. Three hundred and fifty women were evaluated, 200 women having RA and 150 healthy control. The subjects were genotyped for polymorphism at BsmI in VDR and A163G in OPG genes by polymerase chain reaction followed by restriction fragment length polymorphism analysis. BMD was also measured. In A163G, the G allele increased the risk for RA and for the development of osteoporosis. We found a significant association between lower hip (BMD-h) and genotype variants of VDR (BsmI) and OPG A163G in RA patients with osteoporosis. Our results suggested that OPG A163G polymorphism was associated with RA susceptibility and with the development of osteoporosis in these patients. Also, VDR and OPG genes are important candidates for osteoporosis in RA patients.

    BACKGROUND The emerging role of vitamin D in immunology and autoimmune disorders has been a worldwide interest in the last decade. Systemic lupus erythematosus (SLE) patients are particularly at a delicate position predisposing them to suffer from vitamin D deficiency due to the multiple risk factors accompanying the disease. Whether vitamin D deficiency is also involved as a risk factor for developing SLE and affecting its course is a considerable concern. OBJECTIVES The objective of this study was to estimate the prevalence of vitamin D deficiency in SLE patients and its relation to disease. MATERIALS AND METHODS In our observational cross-sectional study, serum levels of vitamin D [25(OH)D] in 60 SLE patients and 30 age- and sex-matched healthy controls were assessed and estimated for deficiency and insufficiency at 10 and 30 ng/mL, respectively. Disease activity was evaluated by SLE disease activity index (SLEDAI), irreversible organ damage by Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI), and severity by Severity of Disease Index. Fatigue was measured by visual analog scale. RESULTS Significantly lower levels of 25(OH)D were found in SLE patients (17.6 ± 6.9 ng/mL) in comparison to controls (79.0 ± 28.7 ng/mL), with a statistically high significant difference (t = −11.2, P < 0.001). High prevalence of vitamin D insufficiency and deficiency was detected as 73.3% and 23.3%, respectively. Vitamin D had a highly significant negative correlation with SLEDAI (r = −0.495, P < 0.001), SLICC (r = −0.431, P < 0.05), and fatigue (r = −0.436, P < 0.05). CONCLUSION Vitamin D deficiency and insufficiency were found to be prevalent in SLE patients in our study and related to disease activity and fatigue. If needed, routine screening and consequent repletion of vitamin D are recommended in SLE patients. Restoring adequate vitamin D levels in SLE patients should be more explored as a potential yet

    Polycystic ovary syndrome (PCOS) is an endocrine disorder which affects 6.6% of women of child-bearing age. Although olfactory dysfunction is frequent in the population and it negatively affects quality of life, neither physicians or patients consider this important. This case-control study included 30 patients diagnosed with PCOS, and 25 healthy age-matched controls. Sniffin' sticks tests (BurghartGmbH, Wedel, Germany) were used to analyze olfactory functions, and the Beck Depression Inventory was used to evaluate depressive symptoms. The total odor score was significantly lower in the PCOS group compared to the control group (pdepression score was higher in the PCOS group (pDepression Score. Patients with PCOS have impaired olfactory function. This might be related to depressive disorders that are also observed in those patients.

    Immobility is an important health concern for the elderly patients and healthcare providers who care for the elderly. The purpose of this study was to test a knowledge discovery method to detect elderly patients with impaired mobility in a large clinical dataset. The research method applied an exploratory design and a data mining classification method (cost sensitive Decision Tree J48 from WEKA) to classify patients. Important factors were identified by the Feature Selection method. The Decision Tree algorithm classified patients in the dataset with 65% sensitivity and 72% specificity for a reduced model. The results were evaluated by 10-fold cross validation. Examples of decision rules were also extracted. The study can be applied to classify different health problems in different populations and serves as a foundation for the development of healthcare decision support systems.

    Full Text Available Abstract Background/Objective Bladder cancer is the commonest type of malignant tumors as a result of schistosomaisis which is a major healthy problem in many subtropical developing countries. The aim of this study is to comparatively elucidate the underlying biochemical tumor markers in schistosomal bladder cancer versus non-schistosomal bladder cancer when compared to normal healthy ones. Methods This work was performed on tissue specimens from total 25 patients and serum samples from total 30 patients versus ten healthy individuals served as control. The investigated parameters in serum are: xanthine oxidase (XO, fructosamine, lactate dehydrogense (LDH, aspartate aminotransferase (AST, alanine aminotransferase (ALT, total proteins, essential and non- essential amino acids profile, hydroxyproline, total immunoglobulin E (IgE and tumor necrosis factor alpha (TNF-α. In addition, the current investigation also extended to study some markers in tumor bladder tissues including, pyruvate kinase enzyme (PK, lactate dehydrogenase (LDH, aspartate aminotransferase (AST and alanine aminotransferase (ALT. Results Results showed that biharzial bladder cancer patients recored more significant elevation in serum XO, fructosamine, LDH, AST, ALT, hydroxyproline, IgE and TNF-α than in bladder cancer patients when compared to control ones. While, in tissues there were significant increase in PK, LDH, AST & ALT activities of schistosomal bladder cancer than in bladder cancer as compared to control healthy patients. Conclusions It could be concluded that, bilharzial and non-bilharzial bladder cancer showed distinct biochemical profile of tumor development and progression which can be taken into consideration in diagnosis of bladder cancer.

    Patients who seek medical care for stress-related mental health problems frequently report cognitive impairments as the most pronounced symptom. The purpose of the present study was to compare cognitive function in patients with stress-related exhaustion with that in healthy controls, using a comprehensive battery of cognitive tests. We also explored whether neuropsychological findings were related to severity of illness measured using the Shirom-Melamed burnout questionnaire and hospital anxiety and depression scale. Thirty-three patients (15 males) and 37 healthy controls (11 males), mean age 46 years [standard deviation (SD) 3.9] and 47 years (SD 4.3), respectively, were included in the final analysis. Five cognitive domains were assessed: (1) speed, attention and working memory, (2) learning and episodic memory, (3) executive functions, (4) visuospatial functions and (5) language. The most pronounced difference between patients and controls was seen on executive function, when tested with a multidimensional test, including aspects of speed, control and working memory. The patients also performed poorer on Digit span, measuring attention span and working memory as well as on learning and episodic memory, when measured as delayed recall and the difference between immediate and delayed recall. Delayed recall was the only test that was significantly related to severity of burnout symptoms among the patients. This could reflect poor cognitive sustainability in the patients with the highest burnout scores, as this particular test was the last one performed during the test session. This study clearly shows that cognitive impairment should be considered when evaluating and treating patients who seek medical care for stress-related exhaustion.

Here we assessed the degree of association between HBV infection and neurological impairment in a large cohort of long-term survivors, HIV-infected patients that experienced multiple therapeutic schemes over time. Methods: A total of 462 HIV-1-infected patients were retrospectively followed up for 10 years for HBV infection and neurological impairment. The patients were tested for immune (flow cytometry and virological parameters of HIV infection (Roche Amplicor, version 1.5/ COBAS AmpliPrep/COBAS TaqMan HIV-1 test and for HBV infection markers (HBsAg, anti HBc: Murex Biotech ELISA tests. Many of these patients have experienced between one and six regimens such as: 2 NRTIs, 3 NRTIs, 2 NRTIs+1 NNRTI, 1 NRTI+1 NNRTI+1 PI, 2 NRTIs+2 PIs. Results: After 10 years 29.87% of the patients presented neurological impairment. Out of them 56.52% were HBV-infected. The prevalence of HIV encephalopathy (HE in our studied cohort was 22.7% and 50.4% of these patients were HBV-infected. The median HIV diagnosis age was 7 and the median age of HE diagnosis was 10. In order to establish a possible correlation between HBV infection and HE we first reviewed and excluded the main risk factors associated with HE at the moment of diagnosis: low weight, anemia, constitutional symptoms, low CD4+count, high plasma HIV-RNA load. No patient was infected with HCV. The groups of patients that presented HE and HBsAg and HE without HBsAg were balanced regarding sex, number of deceased patients, number of class C3 patients, but the patients in first group presented lower CD4 values at HE diagnosis vs patients from second group 2: 44.5 vs 95 cells/µL, p=0.3; lower nadir CD4 count: 38 vs 51 cell/µL, p=0.1; and slightly higher HIV viral load: 5.2 vs 5 log10 copies

    The causes, and characteristics of hearing-impairment were determined prospectively among six thousand, four hundred and twenty-eight (6,428) patients who reported at the Komfo Anokye Teaching Hospital (KATH) with hearing problems. The purpose of the study was to determine the characteristics and some causes of hearing loss of patients who report for management at Komfo Anokye Teaching Hospital. The procedure adopted included a detailed case history, Otoscopy and Pure-tone Audiometry. Of the 6,428 patients, 5,734 (89.9 %) were diagnosed as having significant hearing loss. There were more hearing impaired women than men at all ages. Majority of the patients had mild hearing loss. The overall prevalence of Sensorineural Hearing Loss was more in worse ear than better ear. Again, the occurrence of Sensorineural Hearing Loss was more than other types of hearing loss. Noise, Fever, Presbycusis, Sickness, Meningitis and Meniere's diseases were the major causes of Sensorineural Hearing Loss. Conductive Hearing Loss was attributed in the main to Wax, Foreign Bodies, Otitis Media, and Traumas. These findings have important implications on the need of resources for rehabilitation.

    Full Text Available Background. Cognitive disorders may often lead to professional invalidisation and increasing dependence on the external assistance in every day life. Identification of patients with preserved intellectual status and social adaptation but with mild cognitive impairment (MCI is considered to be an effective measure. MCI detection and timely initiation of treatment in most patients is essential to delay the onset of severe dementia.Objective. Investigating influence of Cellex in patients with chronic cerebral ischemia and MCI.Materials and methods. As a part of non-interventional observational comparative study we evaluated the results of Cellex administration in 90 patients with MCI. Patients were divided into 2 groups. Patients from both groups received 1 course of 10 subcutaneous injections of Cellex drug at the dose of 1 mL, and patients from group 2 received two identical courses with an interval of two months. The survey, which included psychometric testing by using special questionnaires (Mini-Mental State Examination, “Frontal Assessment Battery” and “Clock Drawing” tests, Schulte test was performed before treatment, and at months 1 and 2 after its completion.Results. Neuropsychological examination revealed improvement in the patients state, more pronounced after the 2nd course of therapy.Discussion. Our results provide a basis for using Cellex in patients with chronic cerebral ischemia and MCI, allowing to proceede with further studies on the optimal dosage of that drug.

    CONCLUSIONS: The results highlight the necessity of FISH test for further categorization when gastric cancer cases are equivocal (2+ by IHC to determine eligibility for the targeted therapy. Stepwise increase in the expression of Her2/neu was seen in low-grade dysplasia, high-grade dysplasia and carcinoma cases implying its role in cancer evolution. Overexpression of Her 2/neu in GC patients can be promising in selecting those who can get benefit from anti-Her2/neu target therapy.

    The expansion of store-and-forward teledermatology into underserved regions of the world has long been hampered by the requirement for computers with Internet connectivity. To our knowledge, this study is one of the first to demonstrate the feasibility of teledermatology using newer-generation mobile telephones with specialized software and wireless connectivity to overcome this requirement in a developing country. We sought to demonstrate that mobile telephones may be used on the African continent to submit both patient history and clinical photographs wirelessly to remote expert dermatologists, and to assess whether these data are diagnostically reliable. Thirty patients with common skin diseases in Cairo, Egypt, were given a diagnosis by face-to-face consultation. They were then given a diagnosis independently by local senior dermatologists using teleconsultation with a software-enabled mobile telephone containing a 5-megapixel camera. Diagnostic concordance rates between face-to-face and teleconsultation were tabulated. Diagnostic agreement between face-to-face consultation and the two local senior dermatologists performing independent evaluation by teleconsultation was achieved in 23 of 30 (77%) and in 22 of 30 (73%) cases, respectively, with a global mean of 75%. Limited sample size and interobserver variability are limitations. Mobile teledermatology is a technically feasible and diagnostically reliable method of amplifying access to dermatologic expertise in poorer regions of the globe where access to computers with Internet connectivity is unreliable or insufficient.

    2009-10-01

    Full Text Available Abstract Background Paramedics are often a first point of contact for people experiencing pain in the community. Wherever possible the patient's self report of pain should be sought to guide the assessment and management of this complaint. Communication difficulty or disability such as cognitive impairment associated with dementia may limit the patient's ability to report their pain experience, and this has the potential to affect the quality of care. The primary objective of this study was to systematically locate evidence relating to the use of pain assessment tools that have been validated for use with cognitively impaired adults and to identify those that have been recommended for use by paramedics. Methods A systematic search of health databases for evidence relating to the use of pain assessment tools that have been validated for use with cognitively impaired adults was undertaken using specific search criteria. An extended search included position statements and clinical practice guidelines developed by health agencies to identify evidence-based recommendations regarding pain assessment in older adults. Results Two systematic reviews met study inclusion criteria. Weaknesses in tools evaluated by these studies limited their application in assessing pain in the population of interest. Only one tool was designed to assess pain in acute care settings. No tools were located that are designed for paramedic use. Conclusion The reviews of pain assessment tools found that the majority were developed to assess chronic pain in aged care, hospital or hospice settings. An analysis of the characteristics of these pain assessment tools identified attributes that may limit their use in paramedic practice. One tool - the Abbey Pain Scale - may have application in paramedic assessment of pain, but clinical evaluation is required to validate this tool in the paramedic practice setting. Further research is recommended to evaluate the Abbey Pain Scale and to

    Full Text Available The aims of this study were to investigate concrete and abstract word definition ability (1 between patients with amnestic mild cognitive impairment (aMCI and normal adults and (2 between the aMCI subtypes (i.e., amnestic single-domain MCI and amnestic multidomain MCI; asMCI and amMCI and normal controls. The 68 patients with aMCI (29 asMCI and 39 amMCI and 93 age- and education-matched normal adults performed word definition tasks composed of five concrete (e.g., train and five abstract nouns (e.g., jealousy. Task performances were analyzed on total score, number of core meanings, and number of supplementary meanings. The results were as follows. First, the aMCI patients scored significantly poorer than the normal controls in only abstract word definition. Second, both subtypes of aMCI performed worse than the controls in only abstract word definition. In conclusion, a definition task of abstract rather than concrete concepts may provide richer information to show semantic impairment of aMCI.

    Cardiovascular disease is one of the leading causes of death in patients with advanced renal disease. The objective of this study was to investigate impairments in heart rhythm complexity in patients with end-stage renal disease. We prospectively analyzed 65 patients undergoing peritoneal dialysis (PD) without prior cardiovascular disease and 72 individuals with normal renal function as the control group. Heart rhythm analysis including complexity analysis by including detrended fractal analysis (DFA) and multiscale entropy (MSE) were performed. In linear analysis, the PD patients had a significantly lower standard deviation of normal RR intervals (SDRR) and percentage of absolute differences in normal RR intervals greater than 20 ms (pNN20). Of the nonlinear analysis indicators, scale 5, area under the MSE curve for scale 1 to 5 (area 1-5) and 6 to 20 (area 6-20) were significantly lower than those in the control group. In DFA anaylsis, both DFA α1 and DFA α2 were comparable in both groups. In receiver operating characteristic curve analysis, scale 5 had the greatest discriminatory power for two groups. In both net reclassification improvement model and integrated discrimination improvement models, MSE parameters significantly improved the discriminatory power of SDRR, pNN20, and pNN50. In conclusion, PD patients had worse cardiac complexity parameters. MSE parameters are useful to discriminate PD patients from patients with normal renal function.

    The deficit syndrome, a subgroup within schizophrenia, is characterized by enduring, idiopathic negative symptoms. Theory of mind (ToM), a domain of social cognition, is the ability of attributing mental states to ourselves and other people. ToM impairments have not been investigated earlier in deficit schizophrenia. The aim of the present study was to examine ToM differences between patients with deficit (SZ-D) and non-deficit schizophrenia (SZ-ND). Gender differences were also investigated, and based on the literature a better ToM performance was expected in female patients. The participants were 28 patients with SZ-ND, 30 patients with SZ-D, and 29 healthy control volunteers. The "Reading the Mind in the Eyes Test" was used to asses ToM deficits. Control subjects outperformed both patient groups, while there were no significant differences between the two schizophrenia subgroups. In female subjects, both controls and patients with SZ-ND performed significantly better than the SZ-D subgroup. In male subjects, controls performed significantly better than both patient groups. The "diminished emotional range" and the "curbing of interest" items of the Schedule for the Deficit Syndrome showed significant negative relationship with the ToM score. Our main finding is that female subjects with SZ-ND performed significantly better than female subjects with SZ-D. © 2014.

    Full Text Available Background: Tuberculosis remains a major health problem in developing countries especially with the emergence of multidrug resistant strains. Mendelian Susceptibility to Mycobacterial Disease (MSMD is a rare disorder with impaired immunity against mycobacterial pathogens. Reported MSMD etiologies highlight the crucial role of the Interferon gamma /Interleukin 12 (IFN-g/ IL-12 axis and the phagocyte respiratory burst axis. Purpose: Screen patients with possible presentations for MSMD. Methods: Patients with disseminated BCG infection following vaccination, atypical mycobacterial infections or recurrent tuberculosis infections were recruited from the Primary Immune Deficiency Clinic at Cairo University Specialized Pediatric Hospital, Egypt and immune and genetic laboratory investigations were conducted at Human Genetic of Infectious Diseases laboratory in Necker Medical School, France from 2005-2009. IFN-g level in patient’s plasma as well as mutations in the eight previously identified MSMD-causing genes were explored. Results: Nine cases from eight (unrelated kindreds were evaluated in detail. We detected a high level of IFN-g in plasma in one patient. Through Sanger sequencing, a homozygous mutation in the IFNGR1 gene at position 485 corresponding to an amino acid change from serine to phenylalanine (S485F, was detected in this patient. Conclusion: We report the first identified cases of MSMD among Egyptian patients, including in particular a new IFNGR1 mutation underlying IFN-gR1 deficiency. The eight remaining patients need to be explored further. These findings have implications regarding the compulsory Bacillus Calmette Guerin vaccination policy in Egypt, especially given the high consanguinity rate.

  7. LMWH in cancer patients with renal impairment - better than warfarin?

    2016-04-01

    Venous thromboembolism (VTE) is one of the leading causes of death in cancer patients, which are known to have a 5- to 7-fold increased risk for VTE. The anticoagulant treatment of VTE in cancer patients is less effective with a three-fold increased risk of VTE recurrence compared to non-cancer patients, and it is less safe with more than double rates of major bleeding. Compared to vitamin-K antagonists (VKA), long-term secondary prevention with low molecular weight heparin (LMWH) has been shown to reduce the risk of recurrent VTE in cancer-associated thrombosis (CAT), and therefore, current international guidelines recommend the use of LMWH over VKA. With increasing age, cancer prevalence and VTE incidence increase while renal function decreases. Anti-cancer treatment may impair renal function additionally. Therefore, renal insufficiency is a frequent challenge in CAT patients, which is associated with a higher risk of both bleeding and recurrent VTE. Both VKA and LMWH may be associated with less efficacy and higher bleeding risk in renal insufficiency. Unfortunately, there is a lack of prospective data on renal insufficiency and CAT. A recent sub-analysis from a large randomized controlled trial shows that the bleeding risk in patients with severe renal insufficiency in CAT is not elevated with the use of LMWH compared to VKA while efficacy is maintained. In addition, LMWH treatment has several practical advantages over VKA, particularly in patients with CAT while they are receiving anti-cancer treatment.

    Introduction Data specific to late-life bipolar disorder (BD) are limited. Current research is sparse and present guidelines are not adapted to this group of patients. Objectives We present a literature review on clinical characteristics, comorbidities, and cognitive impairment in patients with late-life BD. This review discusses common comorbidities that affect BD elders and how aging might affect cognition and treatment. Methods Eligible studies were identified in MedLine by the Medical Subject Headings terms “bipolar disorder” and “aged”. We only included original research reports published in English between 2012 and 2015. Results From 414 articles extracted, 16 studies were included in the review. Cardiovascular and respiratory conditions, type II diabetes, and endocrinological abnormalities were observed as highly prevalent. BD is associated with a high suicide risk. Bipolar elderly had an increased risk of dementia and performed worse on cognitive screening tests compared to age-matched controls across different levels of cognition. Despite high rates of medical comorbidity among bipolar elderly, a systematic under-recognition and undertreatment of cardiovascular disease have been suggested. Conclusion There was a high burden of physical comorbidities and cognitive impairment in late-life BD. Bipolar elderly might be under-recorded and undertreated in primary medical care, indicating that this group needs an adapted clinical assessment and specific clinical guidelines need to be established.

    Full Text Available Background. The exercise capacity is a key issue in a diabetic patient’s management, due to its well-known beneficial effects in terms of glycemic control, cardiovascular risk reduction and quality of life improvement. However the exercise capacity of diabetic patients is decreased many times and its determinants are sometimes less known. Our study aimed to assess the effort capacity in a cohort of diabetic patients and to find the main causative factors of its impairment. Method: 61 patients with type-2 diabetes mellitus were enrolled and underwent and transthoracic echocardiography and a cycloergometer exercise testing. Exercise performance was calculated and the influence of clinical data and ultrasound parameters was assessed. Sedentary status of each patient was established from total time/week of at least moderate physical activity. Results: the study group consisted of 48.4 % women, mean age 61.4 (±8.4 years. Disease median duration was 5 years and 21.3 % of the patients presented neuropathy, 4.5 % retinopathy and 6.5 % nephropathy. Exercise capacity was moderately and severe decreased (<5 METs in 37.7 % of patients and in this subgroup the diastolic dysfunction, sedentary behavior and old age has a significantly higher prevalence. Interestingly, by multivariate regression, the sedentary lifestyle was the main determinant of decreased effort capacity (beta-coefficient 1.37, p<0.001, suggesting the potential benefits of physical training in these patients. Conclusion. Our study found a decreased effort capacity in at least one third of the patients and this is mainly due to sedentary lifestyle and deconditioning, the diastolic dysfunction also contributes to decreased effort capacity in diabetic patients.

    2009-08-01

    Full Text Available Abstract Background Adolescent idiopathic scoliosis is characterized by a three-dimensional deviation of the vertebral column and its etiopathogenesis is unknown. Various factors cause idiopathic scoliosis, and among these a prominent role has been attributed to the vestibular system. While the deficits in sensorimotor transformations have been documented in idiopathic scoliosis patients, little attention has been devoted to their capacity to integrate vestibular information for cognitive processing for space perception. Seated idiopathic scoliosis patients and control subjects experienced rotations of different directions and amplitudes in the dark and produced saccades that would reproduce their perceived spatial characteristics of the rotations (vestibular condition. We also controlled for possible alteration of the oculomotor and vestibular systems by measuring the subject's accuracy in producing saccades towards memorized peripheral targets in absence of body rotation and the gain of their vestibulo-ocular reflex. Results Compared to healthy controls, the idiopathic scoliosis patients underestimated the amplitude of their rotations. Moreover, the results revealed that idiopathic scoliosis patients produced accurate saccades to memorized peripheral targets in absence of body rotation and that their vestibulo-ocular reflex gain did not differ from that of control participants. Conclusion Overall, results of the present study demonstrate that idiopathic scoliosis patients have an alteration in cognitive integration of vestibular signals. It is possible that severe spine deformity developed partly due to impaired vestibular information travelling from the cerebellum to the vestibular cortical network or alteration in the cortical mechanisms processing the vestibular signals.

Aims The study aimed to evaluate pancreatic iron overload by T2*-weighted Gradient-echo magnetic resonance imaging (MRI in young beta-thalassemia major patients and to correlate it with glucose disturbances, hepatic hemosiderosis, serum ferritin and splenectomy. Methods Forty thalassemic patients (20 non diabetic, 10 diabetic, and 10 with impaired glucose tolerance were recruited from Pediatric Hematology Clinic, in addition to 20 healthy controls. All patients underwent clinical assessment and laboratory investigations included complete blood count, liver function tests, serum ferritin and oral glucose tolerance test (OGTT. A T2*-weighted gradient-echo sequence MRI was performed with 1.5 T scanner and signal intensity ratio (SIR of the liver and the pancreas to noise were calculated. Results Significant reduction in signal intensity ratio (SIR of the liver and the pancreas was shown in thalassemic patients compared to controls (P Conclusions pancreatic siderosis can be detected by T2* gradient-echo MRI since childhood in thalassemic patients, and is more evident in patients with abnormal glucose tolerance. After splenectomy, iron deposition may be accelerated in the pancreas. Follow up of thalassemic patients using pancreatic MRI together with intensive chelation therapy may help to prevent the development of overt diabetes.

  14. Semantic Processing Impairment in Patients with Temporal Lobe Epilepsy

    Amanda G. Jaimes-Bautista

    2015-01-01

    Full Text Available The impairment in episodic memory system is the best-known cognitive deficit in patients with temporal lobe epilepsy (TLE. Recent studies have shown evidence of semantic disorders, but they have been less studied than episodic memory. The semantic dysfunction in TLE has various cognitive manifestations, such as the presence of language disorders characterized by defects in naming, verbal fluency, or remote semantic information retrieval, which affects the ability of patients to interact with their surroundings. This paper is a review of recent research about the consequences of TLE on semantic processing, considering neuropsychological, electrophysiological, and neuroimaging findings, as well as the functional role of the hippocampus in semantic processing. The evidence from these studies shows disturbance of semantic memory in patients with TLE and supports the theory of declarative memory of the hippocampus. Functional neuroimaging studies show an inefficient compensatory functional reorganization of semantic networks and electrophysiological studies show a lack of N400 effect that could indicate that the deficit in semantic processing in patients with TLE could be due to a failure in the mechanisms of automatic access to lexicon.

    Shaltout, M. A. M.

    We describe a possible participation of Egypt in a future Mars rover Mission. It was suggested that Egypt participate through involvement in the design, building and testing of a drill to obtain sub-surface samples. The Space Research Institute of the Russian Academy of Sciences (IKI), formally invited the Egyptian Ministry of Scientific Research to study the concept for potential use on the Russian Mars 2001 Mission. As one of the objectives of the Marskhod mission was the analysis of sub-surface samples, a drilling mechanism in the payload would be essential. The Egyptian expertise in drill development is associated with the archaeological exploration of the Pyramids. A sophisticated drilling system perforated limestone to a depth of 2 m without the use of lubricants or cooling fluids that might have contaminated the Pit's environment. This experience could have been applied to a drill development Mars 2001 mission, which was unfortunately canceled due to economic problems.

  18. Thermoluminescence (TL) of Egyptian Blue

    1988-01-01

    Egyptian Blue is a synthesized crystalline pictorial pigment with formula CaCuSi/sub 4/O/sub 10/. It has been used in Egypt and Mesopotamia from the 3rd millenium B.C. A preliminary experiment on a recently synthesized sample showed that this pigment is thermoluminescent after ..beta.. irradiation (/sup 90/Sr). As the signal intensity grows linearly with the administered dose within the temperature range commonly used in TL dating, we have been looking for this phenomenon from archaeological pigments. It was encountered with two samples found in excavation. From its intensity and stability we concluded that Egyptian Blue can be dated using TL. This first and positive result encouraged us to extend the method to other types of mineral pigments synthesized by early man, and to suggest that it may be used for direct dating of ancient murals.

It would be presumptuous of me, therefore, and futile, even to try to define the phenomenon. At this stage I would only wish to emphasize the distinction between a) the more ancient version of the "...

    Medicine and literature have been linked from ancient times; proof of this shown by the many doctors who have made contributions to literature and the many writers who have described medical activities and illnesses in their works. An example is The Egyptian, the book by Mika Waltari that provides a masterly narration of the protagonist's medical activity and describes the trepanation technique. The present work begins with the analysis of trepanations since prehistory and illustrates the practice of the trepanation in The Egyptian. The book mentions trepanation frequently and illustrates how to practice it and which instruments are required to perform it. Trepanation is one of the oldest surgical interventions carried out as treatment for cranial trauma and neurological diseases, but it also had the magical and religious purpose of expelling the evil spirits which caused the mental illness, epilepsy, or migraine symptoms. Trepanation is a surgical practice that has been carried out since prehistory to treat post-traumatic epilepsy, migraine, and psychiatric illness. The Egyptian is a book that illustrates the trepan, the trepanation technique, and the required set of instruments in full detail. Copyright © 2010 Sociedad Española de Neurología.

    Visual matching and visual exploration were examined in 7 normal subjects and 20 brain-damaged patients with drawing impairment measured by the Bender Gestalt Visual-Motor Test. Right brain-damaged patients made significantly more errors of rotation and integration than left brain-damaged patients. Selecteded Bender figures were also used as stimuli for both visual matching and visual exploration tests. The ability to match Bender figures was found to be impaired in right but not left brain-damaged patients. All patients showed eye movement and fixation patterns different from those normals. Patients essentially had more fixations and shorter fixation durations. Significant intercorrelations were found between the total Bender Gestalt score and visual matching and visual exploration scores. These findings indicate that visual matching and visual exploration measures can be used to evaluate perceptual impairment in individuals who do not have adequate motor responses or where impaired motor responses may confound interpretations about visual cognitive impairment.

    Complete denture wearers often find it difficult to accept a new denture. Personality traits are among the factors that possibly affect patient satisfaction with a complete denture. Our aim was to investigate the influence of patients' personality on satisfaction with their present denture and after an increase in the occlusal vertical dimension (OVD). Sixty edentulous patients with complete dentures (22 men and 38 women, mean age 66 years, and range 50-75 years) participated in the study. The age of their complete dentures ranged from 5 to 16 years. Patients' personalities were evaluated using the Arabic version of the Eysenck Personality Questionnaire. Their satisfaction with their dentures before and after restoration of the OVD and relining of the mandibular denture was evaluated using two questionnaires (I and II), Patients with a high score of neuroticism were less satisfied with their original dentures and after relining and an increase of OVD compared with patients with an average score in that trait. The personality trait of psychoticism was significant to patients' acceptance of an increase in OVD; that is, patients with a high score were less satisfied with their dentures after increase of OVD than patients with an average score. It is concluded that personality traits affect patients' acceptance of their complete dentures.

    Impaired cognitive function is increasingly recognized in COPD. Yet, the prevalence of cognitive impairment in specific cognitive domains in COPD has been poorly studied. The aim of this cross-sectional observational study was to compare the prevalence of domain-specific cognitive impairment between patients with COPD and non-COPD controls. A neuropsychological assessment was administered in 90 stable COPD patients and 90 non-COPD controls with comparable smoking status, age, and level of education. Six core tests from the Maastricht Aging Study were used to assess general cognitive impairment. By using Z-scores, compound scores were constructed for the following domains: psychomotor speed, planning, working memory, verbal memory, and cognitive flexibility. General cognitive impairment and domain-specific cognitive impairment were compared between COPD patients and controls after correction for comorbidities using multivariate linear and logistic regression models. General cognitive impairment was found in 56.7% of patients with COPD and in 13.3% of controls. Deficits in the following domains were more often present in patients with COPD after correction for comorbidities: psychomotor speed (17.8% vs 3.3%; P<0.001), planning (17.8% vs 1.1%; P<0.001), and cognitive flexibility (43.3% vs 12.2%; P<0.001). General cognitive impairment and impairments in the domains psychomotor speed, planning, and cognitive flexibility affect the COPD patients more than their matched controls. PMID:28031706

However, neurocognitive deficits remain a pronounced consequence of HIV/AIDS. HIV-1 infection targets the central nervous system in subcortical brain areas and leads to high rates of delirium, depression, opportunistic central nervous system infections, and dementia. Long-term HIV replication in the brain occurs in astrocytes and microglia, allowing the virus to hide from antiviral medication and later compromise neuronal function. The associated cognitive disturbance is linked to both viral activity and inflammatory and other mediators from these immune cells that lead to the damage associated with HIV-associated neurocognitive disorders, a general term given for these disturbances. We review the severity and prevalence of the neuropsychiatric complications of HIV including delirium, neurobehavioral impairments (depression, minor cognitive-motor dysfunction, and HIV-associated dementia.

    Over 35 million alcohol-impaired (AI) patients are cared for in emergency departments (EDs) annually. Emergency physicians are charged with ensuring AI patients' safety by identifying resolution of alcohol-induced impairment. The most common standard evaluation is an extemporized clinical examination, as ethanol levels are not reliable or predictive of clinical symptoms. There is no standard assessment of ED AI patients. The objective was to evaluate a novel standardized ED assessment of alcohol impairment, Hack's Impairment Index (HII score), in a busy urban ED. A retrospective chart review was performed for all AI patients seen in our busy urban ED over 24 months. Trained nurses evaluated AI patients with both "usual" and HII score every 2 hours. Patients were stratified by frequency of visits for AI during this time: high (≥ 6), medium (2-5), and low (1). Within each category, comparisons were made between HII scores, measured ethanol levels, and usual nursing assessment of AI. Changes in HII scores over time were also evaluated. A total of 8,074 visits from 3,219 unique patients were eligible for study, including 7,973 (98.7%) with ethanol levels, 5,061 (62.7%) with complete HII scores, and 3,646 (45.2%) with health care provider assessments. Correlations between HII scores and ethanol levels were poor (Pearson's R(2)  = 0.09, 0.09, and 0.17 for high-, medium-, and low-frequency strata). HII scores were excellent at discriminating nursing assessment of AI, while ethanol levels were less effective. Omitting extrema, HII scores fell consistently an average 0.062 points per hour, throughout patients' visits. The HII score applied a quantitative, objective assessment of alcohol impairment. HII scores were superior to ethanol levels as an objective clinical measure of impairment. The HII declines in a reasonably predictable manner over time, with serial evaluations corresponding well with health care provider evaluations. © 2017 by the Society for Academic

    Cognitive impairment, anaemia and chronic kidney disease (CKD) are associated with mortality and disability in chronic heart failure patients. We hypothesized that anaemia and CKD are independent predictors of cognitive impairment in older patients with heart failure. One hundred and ninety community-living elderly patients aged at least 70 years, treated with optimized therapy for heart failure in stable clinical conditions, were prospectively studied. They underwent clinical and multidimensional assessment. Cognitive status was assessed by the Mini Mental State Examination. Cognitive impairment was defined as the Mini Mental State Examination score adjusted by age and educational level below 24. CKD was defined as the Cockcroft-Gault glomerular filtration rate below 60  ml/min and anaemia as haemoglobin below 12  g/dl. Cognitive impairment was diagnosed in 38.9% of patients, CKD in 85.7% and anaemia in 42.6%. Age, female sex, BMI, education less than 5 years, depressive symptoms, anaemia, CKD, disability and worse quality of life were significantly associated with cognitive impairment. Cognitive impairment involved primarily global cognitive deficit, memory, mental speed, attention, calculation and language. A significant relationship between haemoglobin levels and cognitive impairment was found, with the range of 15-16.5  g/dl having the lower prevalence of cognitive impairment (19.4%). At multivariate analysis, advanced age, low education level, anaemia and CKD were independently associated with cognitive impairment. Cox analysis showed that cognitive impairment was an independent predictor of hospitalization for worsening heart failure alone and combined with all-cause death. Cognitive impairment is common in elderly heart failure patients and is independently associated with anaemia and renal dysfunction. Further studies are needed to assess whether optimal treatment of anaemia and CKD may prevent the development of cognitive impairment in heart failure

    Full Text Available Renal impairment is a well-known risk factor for cardiovascular complications, but the effect of different stages of renal impairment on thrombotic/thromboembolic and bleeding complications in patients with atrial fibrillation (AF undergoing percutaneous coronary intervention (PCI remains largely unknown. We sought to evaluate the incidence and clinical impact of four stages of renal impairment in patients with AF undergoing PCI.We assessed renal function by estimated glomerular filtration rate (eGFR and outcomes in 781 AF patients undergoing PCI by using the data from a prospective European multicenter registry. End-points included all-cause mortality, major adverse cardiac and cerebrovascular events (MACCE and bleeding events at 12 months.A total of 195 (25% patients had normal renal function (eGFR ≥90 mL/min, 290 (37% mild renal impairment (eGFR 60-89, 263 (34% moderate renal impairment (eGFR 30-59 and 33 (4% severe renal impairment (eGFR <30. Degree of renal impairment remained an independent predictor of mortality and MACCE in an adjusted a Cox regression model. Even patients with mild renal impairment had a higher risk of all-cause mortality (HR 2.25, 95%CI 1.02-4.98, p=0.04 and borderline risk for MACCE (HR 1.56, 95%CI 0.98- 2.50, p=0.06 compared to those with normal renal function.Renal impairment is common in patients with AF undergoing PCI and even mild renal impairment has an adverse prognostic effect in these patients requiring multiple antithrombotic medications.

Impaired and spared Broca's area, insula, and middle frontal gyrus in the left hemisphere were checked from magnetic resonance imaging and computed tomography scans utilizing Talairach Atlas. Data were analyzed using chi-square test.Insula was significantly impaired in both forms of oral and verbal apraxia and different severities and prominent forms of both apraxias (P < 0.05. Broca's area was slightly less involved than insula in two forms of apraxia.As the damage of insula was more prominent in both forms of apraxias, it seems that oral and verbal apraxia may have commonalities regarding their underlying brain lesions.

    Hepatocellular carcinoma (HCC) is usually asymptomatic in the early stage and does not show elevated alpha-feto protein (AFP). AFP shows 60-80% sensitivity in diagnosing HCC. Glypican3 (GPC-3) is an oncofetal protein that is only detected in HCC cells but not in benign liver tissues, while Carcinoembryonic antigen (CEA) is expressed in various neoplasms including HCC. Although, it is not specific for HCC. Prothrombin induced by vitamin K absence-II (PIVKA-II) is an abnormal prothrombin protein that is increased in the serum of HCC patients. It has higher sensitivity and specificity compared to AFP. The aim of this study is to compare the clinical utility of PIVKA-II with GPC-3, AFP and CEA in diagnosing HCC. This study included 40 patients with HCC, 10 patients with cirrhosis as a benign control group, and 10 apparently healthy volunteers as normal controls. Serum samples were subjected to routine laboratory investigations, measurement of CEA, AFP using MEIA technique (Axsym), glypican3, and PIVKA-II using ELISA technique in the sera of all patients and controls. All markers showed the highest results in the HCC group. Higher concentrations of PIVKA-II were detected in patients with splenomegaly, and in tumors with size (>3cm). Combination of Glypican-3 and PIVKA-II showed the highest sensitivity, while GPC-3 alone and combination of GPC-3 and AFP showed the highest specificity to differentiate HCC from liver cirrhosis and normal controls. GPC-3, PIVKAII, and combination of both showed the highest sensitivity, while GPC-3 alone showed the highest specificity to differentiate HCC from liver cirrhosis. Glypican-3 is the only oncofetal antigen that showed comparable high diagnostic accuracy as PIVKA-II in diagnosing HCC among Egyptian patients. Copyright © 2014.

    Hepatic veno-occlusive disease, also called sinusoidal obstruction syndrome (VOD/SOS), is an unpredictable, potentially life-threatening complication of hematopoietic stem cell transplant conditioning. Severe VOD/SOS, generally associated with multiorgan dysfunction (pulmonary or renal dysfunction), may be associated with >80% mortality. Defibrotide, recently approved in the US, has demonstrated efficacy treating hepatic VOD/SOS with multiorgan dysfunction. Because renal impairment is prevalent in patients with VOD/SOS, this Phase I, open-label, two-part study in adults examined the effects of hemodialysis and severe or end-stage renal disease (ESRD) on defibrotide pharmacokinetics (PK). Part 1 compared defibrotide PK during single 6.25 mg/kg doses infused with and without dialysis. Part 2 assessed defibrotide plasma PK after multiple 6.25 mg/kg doses in nondialysis-dependent subjects with severe/ESRD versus healthy matching subjects. Among six subjects enrolled in Part 1, percent ratios of least-squares mean and 90% confidence intervals (CIs) on dialysis and nondialysis days were 109.71 (CI: 97.23, 123.78) for maximum observed plasma concentration (Cmax); 108.39 (CI: 97.85, 120.07) for area under the concentration–time curve to the time of the last quantifiable plasma concentration (AUC0–t); and 109.98 (CI: 99.39, 121.70) for AUC extrapolated to infinity (AUC0–∞). These ranges were within 80%–125%, indicating no significant effect of dialysis on defibrotide exposure/clearance. In Part 2, defibrotide exposure parameters in six subjects with severe/ESRD after multiple doses (AUC0–t, 113 µg·h/mL; AUC over dosing interval, 113 µg·h/mL; Cmax, 53.8 µg/mL) were within 5%–8% of parameters after the first dose (AUC0–t, 117 µg·h/mL; AUC0–∞, 118 µg·h/mL; Cmax, 54.9 µg/mL), indicating no accumulation. Defibrotide peak and extent of exposures in those with severe/ESRD were ~35%–37% and 50%–60% higher, respectively, versus controls, following

    Visual function is important for optimal orientation in functional and social life, and has an effect on physical and emotional well-being. Visual impairment, therefore, leads to restrictions in all aspects of daily living and is related to quality of life. The aim of this study was to provide information on the causes of visual impairment in patients presenting to their family physician, the spectrum of impairment, and its impact on quality of life for these patients. This descriptive cross-sectional study of 375 adult patients with ocular symptoms was performed in the general outpatient department of the University College Hospital, Ibadan, from July to September, 2009. After checking their presenting visual acuity, the patients were interviewed using the Vision-Related Quality of Life questionnaire to determine the impact of visual impairment on their quality of life. Ophthalmic examinations were performed to determine the causes of visual impairment. The results were analyzed using proportions and percentages. The main causes of visual impairment were cataracts (58.7%), refractive error (19.4%), and glaucoma (2.9%). Visual impairment was found to be associated with advancing age, low education, and unemployment (Pvisual function (64.2%) and social interaction (50.9%). Quality of life was found to be related to the degree of visual impairment, ie, blind patients reported poor quality of life (41.4%) when compared with those having low vision (8.6%) or near normal vision (2.4%, Pvisual impairment. Family physicians need to identify these visually impaired patients early and make timely referrals.

    Full Text Available Aim. To investigate the relationship between high blood pressure (HBP and obesity in Egyptian adolescents. Methods. A cross-sectional study of 1500 adolescents (11–19 years in Alexandria, Egypt, was conducted. Resting BP was measured and measurements were categorized using the 2004 fourth report on blood pressure screening recommendations. Additional measures included height, weight, and waist and hip circumferences. Obesity was determined based on BMI, waist circumference (WC and waist-to-hip ratio (WHR, and waist-to-height ratio (WHtR indicators. Crude and adjusted odds ratios were used as measures of association between BP and obesity. Results. Prevalence rates of prehypertension and hypertension were 5.7% and 4.0%, respectively. Obesity was seen in 34.6%, 16.1%, 4.5%, and 16.7% according to BMI, WHR, WC, and WHtR, respectively. Adjusting for confounders, HBP was significantly associated with overall obesity based on BMI (OR=2.18, 95%, CI=1.38-3.44 and central obesity based on WC (OR=3.14, 95%, CI=1.67-5.94. Conclusion. Both overall obesity and central obesity were significant predictors of HBP in Egyptian adolescents.

    Full Text Available BACKGROUND: Cognitive impairment is associated with a negative prognosis in amyotrophic lateral sclerosis (ALS, as well as with clinical specificity. We investigate neuropsychological function in ALS patients without known genetic mutations in a Korean tertiary clinic. METHODS: Three hundred and eighteen patients were enrolled in a prospective longitudinal cohort from September 2008 to February 2012. At the time of diagnosis of sporadic ALS, we carried out genetic and comprehensive neuropsychological tests on all patients, and collected demographic and clinical characteristics. Six cognitive domains, namely executive function, attention, language, calculation, visuospatial function and memory were evaluated. ANOVA and t-tests were used to assess differences in clinical characteristics and neuropsychological parameters between sporadic ALS patients. The Kaplan-Meier method and Cox proportional hazard model were used for survival analysis. RESULTS: One hundred and sixty-six patients were categorized into five subtypes: normal cognition (ALS pure, cognitive impairment (ALSci, behavioral impairment (ALSbi, frontotemporal dementia (ALS-FTD, and other types of dementia. Seventy patients (70/166, 42.2% were cognitively or behaviorally impaired. Among the impaired patients, eight (8/166, 4.8% had FTD-type dementia and one (1/166, 0.6% was Alzheimer's disease-type. The ALS patients with cognitive impairment (ALSci and with FTD (ALS-FTD were more severely impaired in executive function, attention, language and memory than the cognitively intact ALS patients (ALS pure. In a survival analysis, ALSci (β = 1.925, p = 0.025 and ALS-FTD groups (β = 4.150, p = 0.019 tended to have shorter survival than the ALS pure group. CONCLUSIONS: About half of ALS patients without known genetic variation have cognitive or behavioral impairment. ALS patients with cognitive abnormalities, especially FTD, have a poorer prognosis than those without cognitive impairment. In

    To assess the prevalence of end-of-life visual impairment in patients followed for glaucoma. Data of 122 patients followed for glaucoma who had died between July 2008 and July 2010 and who had visited the ophthalmology outpatient department of a large non-academic Dutch hospital were collected from the medical files. Sixty-one patients had open-angle glaucoma (OAG), and 61 patients were suspect for glaucoma or had ocular hypertension (OHT). Visual impairment was defined as a mean deviation value visual acuity visual impairment on the last patient visit before death and investigated its main explanations. Overall, the mean age at death was 81.8 years after a mean follow-up period of 9.2 years. Seventy-three per cent of all patients had their last visit in the year preceding death. In OAG, 16 patients (26%) had an end-of-life visual impairment. In nine patients (15%), this was caused by glaucoma. Eight of them had substantial visual loss at the initial visit. Six (10%) impaired OAG cases were mainly explained by ocular comorbidity, and there was an equal contribution of comorbidity and glaucoma in one case. Five glaucoma suspects or patients with OHT (8%) were visually impaired at death and these were all caused by ocular comorbidity. The prevalence of end-of-life visual impairment is considerable in patients with OAG. Substantial visual loss at baseline is an important contributing factor. In glaucoma suspects or patients with OHT, the prevalence is lower and can be attributed to ocular comorbidity. © 2012 The Authors.

  9. Neural correlates of out-group bias predict social impairment in patients with schizophrenia.

    Blackford, J U; Williams, L E; Heckers, S

    2015-05-01

    Social impairments are a hallmark feature of schizophrenia and are a key predictor of functional disability. Deficits in social information processing likely underlie social impairment; however, this relationship is understudied. We previously demonstrated that patients with schizophrenia fail to habituate to neutral faces, providing evidence for an alteration in basic social information processing. It remains unknown whether patients with schizophrenia also show deficits in processing of more complex social information. Out-group bias provides an excellent opportunity to test complex social information processing because the bias requires basic face processing skills, the ability to discriminate between groups, as well as the ability to categorize oneself into a salient social group. Study participants were 23 patients with schizophrenia and 21 controls. Using functional magnetic resonance imaging, habituation of response to 120 s of repeated presentations of faces was assessed in participants who viewed either same-gender faces or opposite-gender faces. The interaction between face gender (same/opposite) and group was examined in three key regions: amygdala, hippocampus, and visual cortex. Social impairment was measured using the PANSS and correlations between social impairment and out-group effect (main effect of face type) were performed in patients. Patients with schizophrenia had aberrant neural responses to opposite-gender faces (interaction, psocial impairment. Patients with no social impairment showed a heightened neural response to opposite-gender faces after 30s, whereas patients with mild-moderate social impairment failed to ever show a heightened response. Alterations in neural responses during out-group processing predicted degree of social impairment in patients with schizophrenia; thus, neural responses to opposite-gender faces may provide a novel measure for studies of treatment response and disease outcome.

    Introduction Cognitive impairment in the euthymic phase is a well-established finding in bipolar disorder. However, its brain structural and/or functional correlates are uncertain. Methods Thirty-three euthymic bipolar patients with preserved memory and executive function and 28 euthymic bipolar patients with significant memory and/or executive impairment, as defined using two test batteries, the Rivermead Behavioural Memory Test (RBMT) and the Behavioural Assessment of the Dysexecutive Syndrome (BADS), plus 28 healthy controls underwent structural MRI using voxel-based morphometry (VBM). Twenty-seven of the cognitively preserved patients, 23 of the cognitively impaired patients and 28 controls also underwent fMRI during performance of the n-back working memory task. Results No clusters of grey or white matter volume difference were found between the two patient groups. During n-back performance, the cognitively impaired patients showed hypoactivation compared to the cognitively preserved patients in a circumscribed region in the right dorsolateral prefrontal cortex. Both patient groups showed failure of de-activation in the medial frontal cortex compared to the healthy controls. Conclusions Cognitive impairment in euthymic bipolar patients appears from this study to be unrelated to structural brain abnormality, but there was some evidence for an association with altered prefrontal function.

Despite it attracting increasing attention worldwide, less is known about its prevalence in the Chinese population. The objective of this study was to assess cognitive impairment and related risk factors in Chinese PD patients. Methods: We collected the demographic, diagnostic, and treatment information of 901 PD patients from 42 centers throughout the People's Republic of China, then administered a battery of neuropsychological tests, to assess motor, cognitive, and neuropsychiatric symptoms. Results: Overall, 193 of 901 (21.4% PD patients met the criteria for dementia (PD-D, and 206 (22.8% met the criteria for mild cognitive impairment (PD-MCI. Visuospatial dysfunction and attention/executive impairment predominated. Increased severity of cognitive impairment was associated with greater motor impairment. Patients with psychiatric symptoms, such as depression and hallucinations, were more likely to have dementia. Potentially, the younger-aged and more educated are shown less cognitive impairment, but age at onset, and levodopa equivalent dose, were not associated with the presence of cognitive dysfunction. Conclusion: The prevalence and profile of cognitive impairment in Chinese PD patients, as well as the risk factors, are similar as those reported for other races, but the frequency of nonamnestic cognitive domains differs.

    The proposed dementia precursor state of mild cognitive impairment is emerging as a primary target of aging research. Yet, little is known about the subjective experience of living with a diagnosis of mild cognitive impairment. This study examines, from the patient's perspective, the experience of living with and making sense of the diagnosis. We recruited 12 older adults with amnestic or nonamnestic mild cognitive impairment from a university-based memory disorders clinic. We conducted in-home, semistructured interviews in order to elicit rich descriptions of the personal experience of having mild cognitive impairment. We used the qualitative method of grounded theory to analyze narrative data. Understanding and coming to terms with the syndrome, or assigning meaning, constituted a fundamental aspect of living with a diagnosis of mild cognitive impairment. This process comprised interrelated emotional and cognitive dimensions. Participants employed a range of positive, neutral, and negative phrasing in order to depict their emotional reactions to receiving a diagnosis. Cognitive representations of mild cognitive impairment included both prognosis-focused and face-value appraisals. Expectations of normal aging, personal experience with dementia, and concurrent health problems were key contextual factors that provided the backdrop against which participants assigned meaning to a diagnosis of mild cognitive impairment. Clinicians who disclose diagnoses of mild cognitive impairment need to be mindful of the potential for varying interpretations of the information that is conveyed. Future research needs to include systematic, longitudinal investigations of illness representation and its impact on health behaviors among individuals with mild cognitive impairment.

    The aim of this study was to obtain a more in-depth understanding of cognitive impairments and concerns as described by patients with multiple myeloma and the strategies used to cope with them. Semi-structured qualitative interviews were undertaken with 15 multiple myeloma patients of differing age ranges and at various stages of their disease. Various cognitive impairments, such as problems with short-term memory, poor recall and lack of concentration were observed and/or expressed in at least 10 out of 15 patients, all of them long(er)-term survivors. In some patients cognitive impairments significantly interfered with their personal and professional lives, and for some patients these were described as permanent. The patients used various coping strategies, from denial, taking notes, writing diaries, reading simpler texts, using talking books and videos, to using systems for counting medication to cope with the results of their cognitive impairment. Our findings differ from much of the contemporary literature which states that if cognitive impairments in cancer patients occur, they are mostly mild and transient. More proactive supportive care is needed to help patients with multiple myeloma to cope with poorer cognitive functioning.

  19. Pathways to similar executive impairment: comparison of schizophrenia patients and healthy aging individuals.

    Executive impairment is prominent in schizophrenia, in conditions such as Parkinson's disease and dementia and in healthy aging. Identifying processes that critically constrain executive function can advance investigation of their biological basis and treatment planning. Recent findings that elderly healthy individuals showed similar impairment on conditional exclusion task as schizophrenia patients raised the question whether similar processes are impaired. To test this we compared 56 schizophrenia patients, 57 elderly and 77 young healthy individuals on three executive tests: conditional exclusion, abstraction and inhibition and tests of working memory and psychomotor speed. Schizophrenia patients performed worse than elderly healthy on abstraction, inhibition and verbal working memory. They were similarly impaired on Penn Conditional Exclusion Test (PCET) outcome measures but differed in performance characteristics. Schizophrenia patients needed relatively more trials to learn the first PCET category than the second or the third. This correlated with other cognitive impairments, particularly in working memory. Elderly healthy individuals found it most difficult to learn the last category. The two groups showed different error patterns. We propose that schizophrenia patients have particular difficulty in early (probabilistic) learning ("what to do") while aging individuals have selective impairment in executive integration. These constitute distinct targets for customized treatment in the two conditions.

    Full Text Available Background: Alzheimer's disease (AD and Parkinson's disease (PD are associated with severe cognitive decline, but it is still unclear to what extent they become functionally more similar over time. Methods: We compared amnestic mild cognitively impaired (aMCI; n = 29 patients to mild cognitively impaired (MCI PD patients (n = 25, and patients with AD (n = 34 to patients with PD dementia (PDD; n = 15 with respect to cognitive functioning and mood. Results: aMCI patients were impaired in episodic memory, while MCI PD patients showed deficits in visuoconstruction and attention. AD and PDD patients showed comparable deficits on tests for language, attention and visuoconstruction. However, unlike PDD patients but similar to aMCI patients, AD patients showed a characteristic memory impairment, especially commission errors on recognition tasks, whereas PDD patients scored higher on the depressive mood questionnaire. Conclusions: In advanced stages of both diseases, the pattern of functional deficits associated with parietal and temporal lobe functions (attention, visuoconstruction and language is similar. However, specific differences, already present in the early stage (recognition errors in AD, associated with mediobasal temporal lobe functioning, and depressed mood in PDD, associated with non-motor basal ganglia loops, are also observed in the late stage.

    To retrospectively evaluate the visual and refractive outcome of visually impaired adults treated with refractive surgery (photorefractive keratectomy or laser-assisted in situ keratomileusis). We searched a refractive surgery database comprising 1716 mildly visually impaired patients [best spectacle-corrected visual acuity (BSCVA) on a logMAR scale ≤ -0.1 (Snellen ≤ 0.8)] who had undergone either PRK or LASIK (n = 96). PRK patients who had visits at 5-7, 8-13 and 14-24 months postoperatively were selected. Eleven patients and nine PRK control myopic patients were found (cohort 1). From the same database, 41 visually impaired patients and 54 controls who had a postoperative control at 14-24 months postoperatively were chosen. These patients formed cohort 2. Preoperatively, in cohort 1, the mean BSCVA on a logMAR scale was -0.15 ± 0.13 (Snellen 0.73 ± 0.16) in visually impaired patients and 0.04 ± 0.02 (Snellen 1.11 ± 0.17) in myopic controls. At 14-24 months postoperatively, the mean BSCVA improved to 0.05 ± 0.04 (Snellen 1.13 ± 0.10) in visually impaired patients and 0.05 ± 0.08 (Snellen 1.13 ± 0.21) in control patients. In cohort 2, preoperatively the mean BSCVA on a logMAR scale was -0.15 ± 0.12 (Snellen 0.74 ± 0.14) in visually impaired patients and 0.01 ± 0.03 (Snellen 1.04 ± 0.10) in myopic controls. At 14-24 months postoperatively, the mean BSCVA improved to 0.02 ± 0.07 (Snellen 1.06 ± 0.16) in visually impaired patients and 0.06 ± 0.06 (Snellen 1.15 ± 0.16) in control patients. Refractive surgery improves BSCVA in visually impaired patients, possibly through plastic changes in the visual cortex. Consequently, refractive surgery may be used successfully for the treatment of visually impaired adults to enhance their visual acuity. © 2009 The Authors.

    To describe goblet cell density and Nelson grading in different areas of the ocular surface using conjunctival impression cytology (CIC) among patients with normal and impaired Ocular Surface Disease Index (OSDI) scores. Patients (n=166) under assessment for dry eye were recruited between 2011 and 2012 and classified according to the OSDI score in 4 categories (normal and impaired). Cytological study (CIC plus Papanicolaou staining) using the Nelson grading system, with modifications in staging, and goblet cell counting were performed on the nasal, temporal, inferior, and superior bulbar conjunctival surfaces. Nelson grading was significantly higher in patients with a severely impaired OSDI score (1.41±0.14) compared to normal patients (0.86±0.09) (P<.01). Goblet cell density was significantly reduced in patients with a severely impaired OSDI score (310.24±56.24 cells per sample) compared with normal subjects (497.31±50.07 cells per sample) (P<.001). Compared with the photoexposed bulbar conjunctiva, goblet cell density on the non-photoexposed conjunctiva was significantly higher both in patients with mild (P<.01) and moderate (P<.001) OSDI scores. Patients with severely impaired OSDI scores have less goblet cells and a higher Nelson grade. Goblet cells are more abundant on the non-photoexposed conjunctiva.

    Full Text Available Background/Aims: Cognitive impairment and abnormal structural neuroimaging is common in chronic kidney disease patients. We aimed to explore its association with dialysis modality and the relationship between cognitive impairment and abnormal structural neuroimaging. Methods: Sixty peritoneal dialysis patients and 30 hemodialysis and 30 non-dialyzed stage 3-5 chronic kidney disease patients without history of stroke were enrolled for the study. Participants were matched for age, gender, education, diabetes status, and dialysis duration (if appropriate. Cognitive functions were measured using a battery of recognized instruments. Brain features were examined with 3-dimensional magnetic resonance imaging. Results: Cognitive impairment was significantly more severe in dialysis patients than in non-dialyzed patients. The global and specific cognitive function were not significantly different between patients on peritoneal dialysis and hemodialysis. Hemodialysis patients had more severe white matter hyperintensity, sulcal and ventricular atrophy, and SVIs than other patients. In all groups, higher white matter grade, ventricular grade, and hippocampal atrophy were significantly associated with global cognitive impairment, with hazard ratios of 1.80 (1.22-2.64, 1.67 (1.09-2.57, and 2.49 (1.07-5.77, respectively. White matter grade was also significantly associated with delayed memory (hazard ratio 1.63; 1.12-2.39. Conclusion: Dialysis modality showed no association with cognitive impairment, although hemodialysis patients had more severe neuroimaging abnormalities. For the whole group, white matter hyperintensity, and ventricular and hippocampal atrophy, were independently associated with global cognitive impairment in chronic kidney disease patients.

    Full Text Available OBJECTIVES: To investigate the presence and the nature of cognitive impairment in a large sample of patients with Multiple Sclerosis (MS, and to identify clinical and demographic determinants of cognitive impairment in MS. METHODS: 303 patients with MS and 279 healthy controls were administered the Brief Repeatable Battery of Neuropsychological tests (BRB-N; measures of pre-morbid verbal competence and neuropsychiatric measures were also administered. RESULTS: Patients and healthy controls were matched for age, gender, education and pre-morbid verbal Intelligence Quotient. Patients presenting with cognitive impairment were 108/303 (35.6%. In the overall group of participants, the significant predictors of the most sensitive BRB-N scores were: presence of MS, age, education, and Vocabulary. The significant predictors when considering MS patients only were: course of MS, age, education, vocabulary, and depression. Using logistic regression analyses, significant determinants of the presence of cognitive impairment in relapsing-remitting MS patients were: duration of illness (OR = 1.053, 95% CI = 1.010-1.097, p = 0.015, Expanded Disability Status Scale score (OR = 1.247, 95% CI = 1.024-1.517, p = 0.028, and vocabulary (OR = 0.960, 95% CI = 0.936-0.984, p = 0.001, while in the smaller group of progressive MS patients these predictors did not play a significant role in determining the cognitive outcome. CONCLUSIONS: Our results corroborate the evidence about the presence and the nature of cognitive impairment in a large sample of patients with MS. Furthermore, our findings identify significant clinical and demographic determinants of cognitive impairment in a large sample of MS patients for the first time. Implications for further research and clinical practice were discussed.

    In this study, 46 strabismic patients aged between 9 and 58 years were tested for dynamic stereopsis in the peripheral visual field with up to 20 degrees eccentricity. Squint angles ranged from +30 to -36 degrees. The effect of surgical realignment of the visual axes on dynamic stereopsis was tested before and after surgery in 40 of these patients. Of the 46 patients, 23 had esotropia and 23 exotropia. A test device was used which presented two projected squares in polarized light (each square being perceived monocularly through a polarization filter) in horizontal motion, thus creating a three-dimensional impression. Patients were tested qualitatively for dynamically stereoactive fields of vision and quantitatively for the threshold value needed to create a three-dimensional impression. We found residual dynamic stereopsis in 30% of patients who had no central static stereopsis. 56% of the patients improved after surgery, either through a significant (p traffic and sports medicine, regardless of the effect on classical tests.

    Patients with pre-existing atherothrombotic disease are prone to cognitive impairment. We tested whether impaired cerebrovascular reactivity (CVR), a marker of cerebral microvascular hemodynamic dysfunction, is associated with poorer cognitive scores among patients with and without carotid large-vessel disease. A subgroup of non-demented patients with chronic coronary heart disease followed-up for 15 ± 3 years was assessed for cognitive function (Neurotrax Computerized Cognitive Battery; scaled to an IQ style scale with a mean of 100 and SD of 15) and for CVR using the breath-holding index (BHI) with transcranial Doppler and for carotid plaques using ultrasound. We assessed cognitive scores in specific domains in patients with and without impaired CVR (BHI hemodynamics in cognitive performance.

    Stroke survivors may suffer from a range of hearing impairments that may restrict their participation in postacute rehabilitation programs. Hearing impairment may have a significant impact on listening, linguistic skills, and overall communication of the affected stroke patient. However, no studies sought to systematically characterize auditory function of stroke patients in detail, to establish the different types of hearing impairments in this cohort of patients. Such information would be clinically useful in understanding and addressing the hearing needs of stroke survivors. The present study aimed to characterize and classify the hearing impairments, using a detailed audiological assessment test battery, in order to determine the level of clinical need and inform appropriate rehabilitation for this patient population. A case-control study. Forty-two recruited stroke patients who were discharged from a stroke unit and 40 control participants matched for age. All participants underwent pure-tone audiometry and immittance measurements including acoustic reflex threshold, transient-evoked otoacoustic emissions, auditory-evoked brainstem response, and a central auditory processing assessment battery, performed in a single session. Hearing impairments were classified as peripheral hearing loss (cochlear and neural type), central auditory processing disorder (CAPD), and as a combination of CAPD and peripheral hearing loss. Overall mean hearing thresholds were not significantly different between the control and stroke groups. The most common type of hearing impairment in stroke patients was the combination type, "peripheral and CAPD," in the 61- to 80-yr-old subgroup (in 55%), and auditory processing deficits in 18- to 60-yr-olds (in 40%), which were both significantly higher than in controls. This is the first study to examine hearing function in detail in stroke patients. Given the importance of hearing for the efficiency of communication, it is essential to identify

    The aim of this study was to compare cognitive performance between schizophrenia patients with and without treatment resistance (TRS and non-TRS patients) taking into account psychopathological symptoms and antipsychotic treatment. The following cognitive tests were administered to 53 TRS patients and 32 non-TRS subjects: Rey Auditory Verbal Learning Test (RAVLT), Trail Making Tests (TMT-A and TMT-B), verbal fluency tests (FAS test and Supermarket), as well as selected Wechsler Adults Intelligence Scale (WAIS-R-PI) subtests: Digit Symbol Coding Test, Digit Span Forward and Backward and Similarities. TRS patients performed significantly worse in comparison with non-TRS patients on the measures of processing speed (TMT-A, Stroop test, FAS test, Supermarket test, Digit Symbol Coding test), verbal fluency (FAS test, Supermarket test), cognitive flexibility and executive functions (Stroop test) after controlling for age, illness duration, clinical symptoms severity, the number of years of completed education and antipsychotics' dose. Cognitive performance was associated with negative and general symptomatology. Anticholinergic activity of antipsychotics had debilitating effect on cognitive functioning in non-TRS patients (FAS test) and in TRS patients (TMT-B test, Stroop test, RAVLT subtests, Digit Coding test and Similarities test), while low anticholinergic activity of antipsychotics was associated with better cognitive performance in non-TRS patients (Backward Digit Span test) and in TRS patients (Similarities test). Results of this study indicate that cognitive deficits are more robust in TRS patients than in non-TRS subjects, and are associated with clinical symptoms as well as the treatment with antipsychotics that exert high anticholinergic activity.

    Full Text Available Impairment in consciousness is common in acute stroke patients and is correlated with the clinical outcome after stroke. The underlying mechanism is not completely understood, with little known about brain activity and connectivity changes in acute stroke patients having impaired consciousness. In this study, we investigated changes in regional brain activity and brain networks of consciousness impaired stroke patients, as well as the amplitude of spontaneous low frequency fluctuation (ALFF of each time series. Regional homogeneity (ReHo of each voxel was measured, and resting state network analysis was consequently conducted. Results from this study demonstrate that, compared to normal subjects, the intensities of ALFF and ReHo, as well as the strength of the default mode network (DMN connectivity, were significantly decreased in the precuneus and posterior cingulate cortex regions among stroke patients with impaired consciousness. Furthermore, the strength of the DMN was highly correlated with differences in the Glasgow Coma Scale (GCS scores between the onset time and the scanning time. Results from this study suggest that the resting state fMRI is a feasible tool for the evaluation of acute stroke patients with an early impairment of consciousness. The detailed mechanisms, implications of these brain activities and networks exhibiting changes will require further investigation.

    The circulating form of endothelial progenitors cells (EPCs) are derived from bone marrow (BM)-derived hematopoietic stem cells (HSCs). Enhanced mobilization of EPCs was shown to be linked to cardiac diseases. This study investigated whether reduced EPC levels in advanced coronary heart disease (CHD) are secondary to a functional exhaustion of HSCs in the BM or to reduced mobilization. Number and functional properties of EPCs were assessed in 15 healthy controls, and 40 patients with CHD. The colony-forming unit (CFU) capacity of BM-derived mononuclear cells and the CD34+ HSC number were examined in four healthy volunteers, and 15 CHD patients. EPC number was reduced in CHD patients (P < 0.01 vs. controls). Moreover, the migratory capacity was significantly impaired in EPCs of CHD patients (P < 0.05 vs. controls). On multivariate analysis, CHD was an independent predictor of functional EPC impairment. CFUs were reduced in CHD patients (59.6 +/- 21.2 vs. 75.4 +/- 25.8 in controls, P < 0.05). CHD was also predictor of impaired CFU capacity. In this small clinical study, CHD is associated with selective impairment of HSC function in the BM and in the peripheral blood, which may contribute to impairment of cardiac function.

    Full Text Available PURPOSE To determine the severity and various causes of visual impairment in patients seeking visual disability certificate. METHODS Cross-sectional study of patients seeking visual disability certificate from November 2014 to April 2015 was done. Severity of visual impairment was calculated as per the guidelines of Ministry of Social Justice and Empowerment 1999. Cause was ascertained after detailed examination which included slit-lamp examination, direct ophthalmoscopy, indirect ophthalmoscopy, slit-lamp biomicroscopy with 78D lens, Humphrey visual field analysis wherever necessary.

    2015-08-01

    The objectives of this article are to discuss ethical issues of informed consent in cognitively impaired patients and review considerations for capacity determination. We will also discuss how to evaluate capacity, determine competence, and obtain informed consent when a patient is deemed incompetent. This review emphasizes how to carry out informed consent procedures when capacity is questionable and discusses measures supported for use when determining cognitively impaired patients' ability to consent. Information was gathered from medical and psychological codes of ethics, peer-reviewed journals, published guidelines from health-care organizations (e.g., American Medical Association), and scholarly books. Google Scholar and PsycINFO were searched for articles related to 'informed consent' and 'cognitive impairment' published in English between 1975 and 2014. Relevant sources referenced in retrieved publications were subsequently searched and reviewed. We selected 49 sources generated by our search. Sources were included in our review if they presented information related to at least one of our focus areas. These areas included: review of informed consent ethics and procedures, review of cognitive impairment evaluations, recommendations for measuring cognitive capacity, and alternative forms of informed consent. Patients' cognitive impairments can hinder the ability of patients to understand treatment options. Evaluating the capacity of patients with cognitive impairment to understand treatment options is vital for valid informed consent and should be guided by best practices. Thus, proper identification of patients with questionable capacity, capacity evaluation, and determination of competence, as well as reliance upon appropriate alternative consent procedures, are paramount. © 2015 The Authors.

    Full Text Available BACKGROUND: Cortical changes associated with cognitive decline in Parkinson's disease (PD are not fully explored and require investigations with established diagnostic classification criteria. OBJECTIVE: We used MRI source-based morphometry to evaluate specific differences in grey matter volume patterns across 4 groups of subjects: healthy controls (HC, PD with normal cognition (PD-NC, PD with mild cognitive impairment (MCI-PD and PD with dementia (PDD. METHODS: We examined 151 consecutive subjects: 25 HC, 75 PD-NC, 29 MCI-PD, and 22 PDD at an Italian and Czech movement disorder centre. Operational diagnostic criteria were applied to classify MCI-PD and PDD. All structural MRI images were processed together in the Czech centre. The spatial independent component analysis was used to assess group differences of local grey matter volume. RESULTS: We identified two independent patterns of grey matter volume deviations: a Reductions in the hippocampus and temporal lobes; b Decreases in fronto-parietal regions and increases in the midbrain/cerebellum. Both patterns differentiated PDD from all other groups and correlated with visuospatial deficits and letter verbal fluency, respectively. Only the second pattern additionally differentiated PD-NC from HC. CONCLUSION: Grey matter changes in PDD involve areas associated with Alzheimer-like pathology while fronto-parietal abnormalities are possibly an early marker of PD cognitive decline. These findings are consistent with a non-linear cognitive progression in PD.

    Research on oculopharyngeal muscular dystrophy focuses mainly on genetic and pathophysiological aspects. Clinically, oculopharyngeal muscular dystrophy is often considered as a disease with a relatively mild initial disease course with no or only mild functional disabilities. However the occurrence of fatigue, pain and functional impairments other than dysphagia has never been studied systematically. The aim of this study is therefore to assess the prevalence of fatigue, pain, and functional limitations, and the social participation and psychological well-being of oculopharyngeal muscular dystrophy patients. We performed a questionnaire study on fatigue, pain, functional impairments, social participation and psychological distress in 35 genetically confirmed oculopharyngeal muscular dystrophy patients with an average disease duration of 11.6 years. We showed that 19 (54%) of the patients experienced severe fatigue and also 19 (54%) experienced pain. Limitations in daily life activities and social participation were detected in 33 (94%) of the patients. Many patients reported pelvic girdle weakness and limitations in ambulation. Fatigue severity was related to functional impairments, while pain and disease duration were not. Psychological distress was not different from healthy adults. In conclusion, fatigue and pain are present among approximately half of the patients, and almost all patients are impaired in daily life activities, social participation and ambulation. These data should be taken into account in symptomatic management of oculopharyngeal muscular dystrophy.

    Although this effect is well known, tailored treatment methods have not yet been broadly adopted. The aim of this study was to identify those patient characteristics that most influence the impairment of quality of life and thus to identify those patients who need and can benefit most from specific intervention treatment. 1879 cancer patients were given the EORTC QLQ C-30 questionnaire at the beginning and end of their inpatient rehabilitation. Patients' scores were compared to those of 2081 healthy adults (Schwarz and Hinz, Eur J Cancer 37:1345-1351, 2001). Furthermore, differences in quality of life corresponding to sex, age, tumor site, TNM stage, interval between diagnosis and rehabilitation, and therapy method were examined. Compared to the healthy population, the study group showed a decreased quality of life in all analyzed domains. This difference diminished with increasing age. Women reported a lower quality of life then men in general. Patients with prostate cancer showed the least impairment in several domains. Patients having undergone chemotherapy as well as radiotherapy were impaired the most. Surprisingly, TNM stage and interval between diagnosis and rehabilitation did not significantly influence quality of life. Global quality of life and all functional domains significantly improved after a 3-week rehabilitation program. Despite an individualized and increasingly better tolerable therapy, the quality of life of cancer patients is still considerably impaired. However, systematic screening of psychosocial aspects of cancer, e.g. quality of life, could enable improved intervention.

    The aims of this study were to study the mobility recovery in hip fracture patients and determine the influence of cognitive impairment on mobility within the first 3 months after surgery. This prospective cohort study was carried out in an acute public hospital in southern Spain and included 275 patients, 65 years or older, with a hip fracture. Mobility and Cognitive status were measured by Tinetti Performance-Oriented Mobility Assessment and Pfeiffers' Scale (Short Portable Mental State Questionnaire), respectively. Multiple linear regression was used to examine the influence of cognitive impairment on mobility. The median Performance-Oriented Mobility Assessment score changed from 4 (3-4) points at discharge to 17 (7-22) at 3 months. All degrees of cognitive impairment were negatively associated with gait and balance at 1 and 3 months after surgery (P < 0.01). Age, weight bearing, length of hospital stay, and postsurgical complications were also identified as independent predictors of mobility outcome at 3 months. Cognitive impairment is a negative prognostic factor for the recovery of mobility in elderly patients with a hip fracture. New treatment strategies are needed for hip fracture patients with cognitive impairment.

    Impairment in facial emotion perception is believed to be associated with aggression. Schizophrenia patients with antisocial features are more impaired in facial emotion perception than their counterparts without these features. However, previous studies did not define the comorbidity of antisocial personality disorder (ASPD) using stringent criteria. We recruited 30 participants with dual diagnoses of ASPD and schizophrenia, 30 participants with schizophrenia and 30 controls. We employed the Facial Emotional Recognition paradigm to measure facial emotion perception, and administered a battery of neurocognitive tests. The Life History of Aggression scale was used. ANOVAs and ANCOVAs were conducted to examine group differences in facial emotion perception, and control for the effect of other neurocognitive dysfunctions on facial emotion perception. Correlational analyses were conducted to examine the association between facial emotion perception and aggression. Patients with dual diagnoses performed worst in facial emotion perception among the three groups. The group differences in facial emotion perception remained significant, even after other neurocognitive impairments were controlled for. Severity of aggression was correlated with impairment in perceiving negative-valenced facial emotions in patients with dual diagnoses. Our findings support the presence of facial emotion perception impairment and its association with aggression in schizophrenia patients with comorbid ASPD.

It remains unclear whether the systemic immune response contributes to impairment of fracture healing in multitrauma patients. It is well known that systemic inflammatory changes after major trauma affect leukocyte kinetics. We therefore retrospectively compared the cellular composition of peripheral blood during the first 2 weeks after injury between multitrauma patients with normal (n=48 and impaired (n=32 fracture healing of the tibia. The peripheral blood-count curves of leukocytes, neutrophils, monocytes, and thrombocytes differed significantly between patients with normal and impaired fracture healing during the first 2 weeks after trauma (P-values were 0.0122, 0.0083, 0.0204, and <0.0001, respectively. Mean myeloid cell counts were above reference values during the second week after injury. Our data indicate that leukocyte kinetics differ significantly between patients with normal and impaired fracture healing during the first 2 weeks after major injury. This finding suggests that the systemic immune response to major trauma can disturb tissue regeneration. Keywords: SIRS, inflammation, neutrophils, myelopoiesis, regeneration

  16. Can paracetamol (acetaminophen) be administered to patients with liver impairment?

    2016-02-01

    Although 60 years have passed since it became widely available on the therapeutic market, paracetamol dosage in patients with liver disease remains a controversial subject. Fulminant hepatic failure has been a well documented consequence of paracetamol overdose since its introduction, while short and long term use have both been associated with elevation of liver transaminases, a surrogate marker for acute liver injury. From these reports it has been assumed that paracetamol use should be restricted or the dosage reduced in patients with chronic liver disease. We review the factors that have been purported to increase risk of hepatocellular injury from paracetamol and the pharmacokinetic alterations in different pathologies of chronic liver disease which may affect this risk. We postulate that inadvertent under-dosing may result in concentrations too low to enable efficacy. Specific research to improve the evidence base for prescribing paracetamol in patients with different aetiologies of chronic liver disease is needed.

    Intense visual training can lead to partial recovery of visual field defects caused by lesions of the primary visual cortex. However, the standard visual detection and discrimination tasks, used to assess this recovery process tend to ignore the complexity of the natural visual environment, where multiple stimuli continuously interact. Visual competition is an essential component for natural search tasks and detecting unexpected events. Our study focused on visual decision-making and to what extent the recovered visual field can compete for attention with the 'intact' visual field. Nine patients with visual field defects who had previously received visual discrimination training, were compared to healthy age-matched controls using a saccade target-selection paradigm, in which participants actively make a saccade towards the brighter of two flashed targets. To further investigate the nature of competition (feed-forward or feedback inhibition), we presented two flashes that reversed their intensity difference during the flash. Both competition between recovered visual field and intact visual field, as well as competition within the intact visual field, were assessed. Healthy controls showed the expected primacy effect; they preferred the initially brighter target. Surprisingly, choice behaviour, even in the patients' supposedly 'intact' visual field, was significantly different from the control group for all but one. In the latter patient, competition was comparable to the controls. All other patients showed a significantly reduced preference to the brighter target, but still showed a small hint of primacy in the reversal conditions. The present results indicate that patients and controls have similar decision-making mechanisms but patients' choices are affected by a strong tendency to guess, even in the intact visual field. This tendency likely reveals slower integration of information, paired with a lower threshold. Current rehabilitation should therefore also

    Mucopolysaccharidosis type III (MPS III) is an autosomal recessive disorder caused by deficiency of a specific enzyme leading to heparan sulfate (HS) accumulation within cells and to eventual progressive cerebral and systemic organ abnormalities. Different enzyme deficiencies comprise the MPS III subcategories (A, B, C, D). Since neuropathological manifestations are common to all MPS III types, determining blood-brain barrier (BBB) condition may be critical to understand potential additional disease mechanisms. We investigated BBB integrity in various brain structures of post-mortem tissues from an eleven year old Caucasian female with MPS III A and from a twenty four year old Caucasian female with MPS III D. Control tissues were obtained post-mortem from three Caucasians without neurological deficits: a twelve year old male, a twenty four year old female, and a twenty seven year old female. BBB capillary ultrastructure (electron microscopy) and capillary functional integrity (IgG leakage, tight junction proteins, and lysosomal accumulation within endothelium) were examined. Compromised BBB integrity was found in both MPS III cases. Major study findings were: (1) capillary endothelial and pericyte cell damage; (2) mucopolysaccharide bodies in a majority of endothelial cells and pericytes rupturing cell membranes; (3) severe extracellular edema; (4) IgG microvascular leakage and reductions of occludin and claudin-5 with variations between MPS III types; (5) extensive lysosomal accumulation in capillary endothelium. These new findings of BBB structural and functional impairment, although from only two cases, MPS III A and III D, may have implications for disease pathogenesis and should be considered in treatment development for MPS III.

    Full Text Available Background/Aims: Proverb interpretation is assumed to reflect executive functions. We hypothesized that proverb interpretation is impaired in patients with amnestic mild cognitive impairment (aMCI diagnosed as single-domain impairment by common neuropsychological testing. Methods: We compared performance in a proverb interpretation test in single-domain aMCI patients and patients with early Alzheimer’s disease (EAD. Results: The groups with aMCI and EAD performed significantly worse than healthy controls. Both patient groups gave concrete answers with a similar frequency. However, patients with EAD tended to give senseless answers more frequently. Conclusions: Our data suggest that in patients diagnosed as single-domain aMCI, deterioration of executive functions is detectable with subtle and appropriate neuropsychological testing. Implementation of these procedures may improve the early prediction of AD.

    Impaired anti-inflammatory ability of high-density lipoprotein (HDL) has been demonstrated in patients with type-2 diabetes mellitus (T2DM). However, whether HDL from patients with diabetic nephropathy (DN) suffers additional damage remains unknown. This study compared the anti-inflammatory capacities of HDL from healthy controls, T2DM patients with normal renal function, and T2DM patients with DN. HDL was isolated from healthy controls (n=33) and T2DM patients with normal renal function (n=21), chronic kidney disease (CKD) (n=27), and end-stage renal disease (ESRD) (n=27). Human peripheral blood mononuclear cells (PBMCs) from healthy volunteers were pretreated with HDL (100μg/mL) for 1h, then incubated with lipopolysaccharide (LPS) (50ng/mL) for 24h. The anti-inflammatory ability of HDL was measured as the secretion of TNF-α in LPS-activated monocytes. The anti-inflammatory ability of HDL was gradually impaired as kidney function declined. Serum amyloid A (SAA) concentration in HDL(DN) significantly increased and was positively correlated with the impaired anti-inflammatory ability of HDL (Pearson r=0.315, P=0.006). Furthermore, HDL supplemented with SAA significantly increased TNF-α release from PBMCs compared with that from control HDL. These findings identified an impaired anti-inflammatory capacity of HDL from DN patients, which might be attributable to SAA enrichment. Copyright © 2017 Elsevier Inc. All rights reserved.

  3. Orientation of Egyptian Temples: An Overview

    Science.gov (United States)

    Belmonte, Juan Antonio

    Archaeoastronomy has never been a favored discipline within Egyptology. As a consequence, important questions such as the orientation of Egyptian temples and the relevance of astronomy in this respect had not been treated with the requisite seriousness and depth. This situation is changing, however, and over the past decade, there have been several serious attempts to perform an extensive analysis of the orientation of Egyptian monuments. The orientations of approximately 400 temples have been measured in the Nile Valley, the Delta, the Oases, and the Sinai, with the aim of providing a clear answer to the question of whether the ancient Egyptian sacred constructions were astronomically aligned or not. This impressive set of data seems to answer this question in the affirmative.

    Evidence suggests that autism and schizophrenia share similarities in genetic, neuropsychological and behavioural aspects. Although both disorders are associated with theory of mind (ToM) impairments, a few studies have directly compared ToM between autism patients and schizophrenia patients. This study aimed to investigate to what extent high-functioning autism patients and schizophrenia patients share and differ in ToM performance. Thirty high-functioning autism patients, 30 schizophrenia patients and 30 healthy individuals were recruited. Participants were matched in age, gender and estimated intelligence quotient. The verbal-based Faux Pas Task and the visual-based Yoni Task were utilised to examine first- and higher-order, affective and cognitive ToM. The task/item difficulty of two paradigms was examined using mixed model analyses of variance (ANOVAs). Multiple ANOVAs and mixed model ANOVAs were used to examine group differences in ToM. The Faux Pas Task was more difficult than the Yoni Task. High-functioning autism patients showed more severely impaired verbal-based ToM in the Faux Pas Task, but shared similar visual-based ToM impairments in the Yoni Task with schizophrenia patients. The findings that individuals with high-functioning autism shared similar but more severe impairments in verbal ToM than individuals with schizophrenia support the autism-schizophrenia continuum. The finding that verbal-based but not visual-based ToM was more impaired in high-functioning autism patients than schizophrenia patients could be attributable to the varied task/item difficulty between the two paradigms.

    It has been previously demonstrated that a cognitive bias against disconfirmatory evidence (BADE) is associated with delusions. However, small samples of delusional patients, reliance on difference scores and choice of comparison groups may have hampered the reliability of these results. In the present study we aimed to improve on this methodology with a recent version of the BADE task, and compare larger groups of schizophrenia patients with/without delusions to obsessive-compulsive disorder (OCD) patients, a population with persistent and possibly bizarre beliefs without psychosis. A component analysis was used to identify cognitive operations underlying the BADE task, and how they differ across four groups of participants: (1) high-delusional schizophrenia, (2) low-delusional schizophrenia, (3) OCD patients and (4) non-psychiatric controls. As in past studies, two components emerged and were labelled 'evidence integration' (the degree to which disambiguating information has been integrated) and 'conservatism' (reduced willingness to provide high plausibility ratings when justified), and only evidence integration differed between severely delusional patients and the other groups, reflecting delusional subjects giving higher ratings for disconfirmed interpretations and lower ratings for confirmed interpretations. These data support the finding that a reduced willingness to adjust beliefs when confronted with disconfirming evidence may be a cognitive underpinning of delusions specifically, rather than obsessive beliefs or other aspects of psychosis such as hallucinations, and illustrates a cognitive process that may underlie maintenance of delusions in the face of counter-evidence. This supports the possibility of the BADE operation being a useful target in cognitive-based therapies for delusions.

    Systemic concentrations of interleukin-6 (IL-6) are elevated in patients with liver cirrhosis, and impaired hepatic uptake of IL-6 was suggested to contribute to higher levels in these patients. To test this hypothesis IL-6 was measured in portal venous serum (PVS), hepatic venous serum (HVS) and systemic venous serum (SVS) of 41 patients with liver cirrhosis and four patients with normal liver function. IL-6 was higher in PVS than HVS of all blood donors and about 43% of portal vein derived IL-6 was extracted by the healthy liver, and 6.3% by the cirrhotic liver demonstrating markedly impaired removal of IL-6 by the latter. Whereas in patients with CHILD-PUGH stage A IL-6 in HVS was almost 25% lower than in PVS, in patients with CHILD-PUGH stage C IL-6 was similarly abundant in the two blood compartments. Ascites is a common complication in cirrhotic patients and was associated with higher IL-6 levels in all blood compartments without significant differences in hepatic excretion. Hepatic venous pressure gradient did not correlate with the degree of hepatic IL-6 removal excluding hepatic shunting as the principal cause of impaired IL-6 uptake. Furthermore, patients with alcoholic liver cirrhosis had higher IL-6 in all blood compartments than patients with cryptogenic liver cirrhosis. Aetiology of liver cirrhosis did not affect hepatic removal rate indicating higher IL-6 synthesis in patients with alcoholic liver cirrhosis. In summary, the current data provide evidence that impaired hepatic removal of IL-6 is explained by hepatic shunting and liver dysfunction in patients with liver cirrhosis partly explaining higher systemic levels.

    Hepatitis viral infection is hyperendemic in Egypt, western Asia and Africa. However, little is known about the status of hepatitis viruses among rural Egyptian children. Therefore, this study sought to examine the prevalence and characteristics of hepatitis viruses among symptomatic Egyptian children. Serological and molecular analyses of hepatitis viral infection were conducted in 33 children hospitalised at Mansoura University with symptomatic hepatic dysfunction (mean ± standard deviation age, 9.7±3.4 years; alanine aminotransferase level, 130±68 IU/ml). Eleven children (33%) were positive for anti-haemagglutination-IgM and were diagnosed with acute hepatitis A. Hepatitis B surface antigen (HBsAg) and anti‑hepatitis C virus (HCV) were detected in 9 (27%) and 7 (21%) children, respectively, indicating acute-on-chronic infection with hepatitis viruses. None of the children was positive for anti‑hepatitis B core antigen-IgM. Phylogenetic analysis confirmed that all HBVs belonged to genotype D (subgenotype D1) and that HCV belonged to genotypes 4a and 1g. HBV-DNA was detected in 9 children (27%) in the pre-S/S region and in 16 children (48%) in the core promoter/precore region. The Y134F amino acid mutation in the 'α' determinant region was detected in all of the patients. The A1762T/G1764A double mutation, and the T1846A and G1896A single mutations were common in children with occult HBV infection. In conclusion, hepatitis viral infection, including acute-on-chronic infection with HCV and HBV, is common in Egyptian children hospitalised with acute hepatitis.

    The literature concerning social cognitive performance in people with bipolar disorder (BD) reveals a mixed pattern of findings. We compared performance between patients with BD and matched controls on two social cognitive tasks that involved: (i) the decoding of mental states from pictures of eyes (Reading the Mind in the Eyes Test), and (ii) a video-based test that requires participants to discriminate social cues to make interpersonal judgments (Interpersonal Perception Task-15; IPT-15). We also sought to evaluate the association between symptom severity, social functioning, and social cognitive ability in patients with BD. Relative to controls, patients with BD were impaired at discriminating mental states from pictures of eyes and in making complex social judgments. Impaired responding on the IPT-15 was also associated with reduced psychosocial functioning. These results provide evidence of impaired performance on complex tests of social cognition in patients with BD. Impairments in social cognition may be associated with well-documented declines in the frequency of social interactions and development of interpersonal relationships found in this patient population.

  15. Do CSF Biomarkers Predict Progression to Cognitive Impairment in Parkinson's disease patients? A Systematic Review.

    2015-12-01

    Many patients with Parkinson's disease (PD) will develop cognitive impairment. Cross-sectional studies have shown that certain protein levels are altered in the cerebrospinal fluid (CSF) of PD patients with dementia and are thought to represent potential biomarkers of underlying pathogenesis. Recent studies suggest that CSF biomarker levels may be predictive of future risk of cognitive decline in non-demented PD patients. However, the strength of this evidence and difference between specific CSF biomarkers is not well delineated. We therefore performed a systematic review to assess if levels of specific CSF protein biomarkers are predictive of progression to cognitive impairment. Nine articles were identified that met inclusion criteria for the review. Findings from the review suggest a convergence of evidence that a low baseline Aβ42 in the CSF of non-demented PD patients predicts development of cognitive impairment over time. Conversely, there is limited evidence that CSF levels of tau, either total tau or phosphorylated tau, is a useful predictive biomarker. There are mixed results for other CSF biomarkers such as α-synuclein, Neurofilament light chain, and Heart fatty acid-binding protein. Overall the results of this review show that certain CSF biomarkers have better predictive ability to identify PD patients who are at risk for developing cognitive impairment. Given the interest in developing disease-modifying therapies, identifying this group will be important for clinical trials as initiation of therapy prior to the onset of cognitive decline is likely to be more efficacious.

    The most common and problematic side effect of statins is myopathy. To date, the patho-physiological mechanisms of statin myotoxicity are still not clearly understood. In previous studies, we showed that acute application in vitro of simvastatin caused impairment of mitochondrial function and dysfunction of calcium homeostasis in human and rat healthy muscle samples. We thus evaluated in the present study, mitochondrial function and calcium signaling in muscles of patients treated with statins, who present or not muscle symptoms, by oxygraphy and recording of calcium sparks, respectively. Patients treated with statins showed impairment of mitochondrial respiration that involved mainly the complex I of the respiratory chain and altered frequency and amplitude of calcium sparks. The muscle problems observed in statin-treated patients appear thus to be related to impairment of mitochondrial function and muscle calcium homeostasis, confirming the results we previously reported in vitro. -- Highlights: ► The most common and problematic side effect of statins is myopathy. ► Patients treated with statins showed impairment of mitochondrial respiration. ► Statins-treated patients showed altered frequency and amplitude of calcium sparks.

    To investigate whether the processing of the visual appearance of one's own body, that is the corporeal self is a unified or modular function we submitted eight right brain-damaged (RBD) patients and a group of fourteen age-matched neurologically healthy subjects, to a visual matching-to-sample task testing for corporeal self processing. If corporeal self processing is a unique function (i.e., body- and face-parts are processed by the same network), patients impaired in self body-parts (i.e., showing no self-advantage) should be impaired also in self face-parts; alternatively, if corporeal self processing is a modular function (i.e., body- and face-parts are processed by different networks), patients impaired in self body-parts should be unimpaired in self face-parts, unless the face-module is also damaged by the lesion. Results showed that healthy participants were more accurate in processing pictures representing their own as compared to other people's body- and face-parts, showing the so-called self-advantage. The patients' findings revealed a simple dissociation, in that patients who were impaired in the processing of self-related body-parts showed a preserved self-advantage when processing self-related face-parts, thus providing initial evidence of a modular representation of the corporeal self.

    Full Text Available Abstract Background The event-related desynchronization (ERD in EEG is known to appear during motor imagery, and is thought to reflect cortical processing for motor preparation. The aim of this study is to examine the modulation of ERD with motor impairment in ALS patients. ERD during hand motor imagery was obtained from 8 ALS patients with a variety of motor impairments. ERD was also obtained from age-matched 11 healthy control subjects with the same motor task. The magnitude and frequency of ERD were compared between groups for characterization of ALS specific changes. Results The ERD of ALS patients were significantly smaller than those of control subjects. Bulbar function and ERD were negatively correlated in ALS patients. Motor function of the upper extremities did was uncorrelated with ERD. Conclusions ALS patients with worsened bulbar scales may show smaller ERD. Motor function of the upper extremities did was uncorrelated with ERD.

    Internal tandem duplication (ITD) of the FLT3 gene (FLT3/ITD) has been linked to poor outcome in acute myeloid leukemia (AML). However, the prognostic value of FLT3/ITD in various cytogenetic risk groups is still a matter of debate. The aim of this study was to evaluate the prognostic significance of FLT3/ITD in patients with de novo AML and normal or favorable risk cytogenetics (NFC-AML). Blood samples from 39 patients with AML were subjected to PCR of exons 14 and 15 of the FLT3 gene. Patients included 25 with normal cytogenetics, 8 with t(15;17), 4 with t(8;21) and 2 with inv(16). FLT3/1ITD was found in 6/39 (15.4%) patients, 4 of them showed normal cytogenetic, 1 positive for t(15;17) and 1 positive for t(8;21). Patients were M1 3/13, M2 2/12, M3 1/9, M4 0/4 and M5 0/1. The patients were followed up for a mean of 34.5 +/- 2.3 months. The complete remission (CR) rates for the FLT3/ITD+ and FLTITD- groups were 50% vs 63.6%, while the relapse rates were 50% vs 28.6% respectively. Interestingly, disease free survival (DFS) at 3 years was significantly different in studied patients: DFS was 5% in patients with FLT3/ITD+ vs 30% of patients with FLT3/ITD- (P = 0.001). Our data suggest a possible high prognostic value of FLT3/ITD in patients with normal/favorable cytogenetics.

    Full Text Available The Th2 immune response in chronic schistosomiasis is associated with the development of periportal fibrosis. However, little is known about the phenotype and activation status of T cells in the process. Objective. To evaluate the profile of T cells in schistosomiasis patients with periportal fibrosis. Methods. It was a cross-sectional study, conducted in the village of Agua Preta, Bahia, Brazil, which included 37 subjects with periportal fibrosis determined by ultrasound. Peripheral blood mononuclear cells were obtained by the Ficcol-hypaque gradient and the frequency of T cells expressing the surface markers CD28, CD69, CD25, and CTLA-4 was determined by flow cytometry. Results. The frequency of CD4+CD28+ T lymphocytes was higher in individuals with moderate to severe fibrosis compared to patients with incipient fibrosis. We did not observe any significant difference in the frequency of CD4+ T cells expressing CD69 among groups of individuals. There was also no significant difference in the frequency of CD8+ T cells expressing CD28 or CD69 among the studied groups. Individuals with moderate to severe fibrosis presented a lower frequency of CD8+ T cells, CD4+CD25high T cells, and CD4+CTLA-4+ T cells when compared to patients without fibrosis or incipient fibrosis. The frequency of CD4+CD25low cells did not differ between groups. Conclusion. The high frequency of activated T cells coinciding with a low frequency of putative Treg cells may account for the development of periportal fibrosis in human schistosomiasis.

    Continuous cycling peritoneal dialysis (CCPD) uses a cycler to perform dialysis exchanges and requires the patient to respond to an audible alarm signifying an interruption in the therapy. Consequently, an unassisted hearing-impaired patient could not use the system. By converting the standard alarm to a vibrating signal, the cycler was successfully adapted to accommodate the special needs of our hearing-impaired patient. The items required for the modification were the Sonic Alert Wake Up Alarm (Model SA-WA300: Sonic Alert, Troy, MI, U.S.A.) and the Sonic Alert Super Shaker Bed Vibrator (Model SA-SS120V: Sonic Alert). The patient can place the vibrator under either the pillow or the mattress. When the cycler alarm is activated, vibration wakens the patient. The equipment was purchased from Harris Communications (Eden Prairie, MN, U.S.A.) through a referral by the Easter Seal Society. Three days were needed to complete training compared to an average of one or two days for patients previously trained for continuous ambulatory peritoneal dialysis (CAPD). The patient remained on cycler therapy for approximately four months when the unrelated development of an abdominal hernia required termination of peritoneal dialysis and subsequent transfer to hemodialysis. In conclusion, a modified cycler can provide a safe and efficient renal replacement therapy option for a hearing-impaired patient.

    Impaired dexterity is a major psychomotor deficit reported in patients with schizophrenia. In the present study, the Purdue pegboard test was used to compare the manual dexterity in patients with schizophrenia and healthy controls. We also examined the influence of antipsychotics, benzodiazepines, and benzodiazepine-like drugs on manual dexterity. Subjects were 93 patients with schizophrenia and 93 healthy controls, matched for sex and age distributions. Control subjects scored significantly higher on all scores of Purdue pegboard than patients with schizophrenia. Age, PANSS negative symptom scale, typical antipsychotic dose, and use of benzodiazepines and/or benzodiazepine-like drugs were negatively correlated with the pegboard scores in patients with schizophrenia. The present results indicate that patients with schizophrenia have impaired gross and fine fingertip dexterity compared to healthy controls. The use of typical antipsychotics and benzodiazepines and/or benzodiazepine-like drugs, but not atypical antipsychotics, had significant negative impact on dexterity in patients with schizophrenia. Psychiatrists should be aware that some psychotropic medications may enhance the disability caused by the impairment of dexterity in patients with schizophrenia.

    2012-01-01

    Semantic dementia is characterized by semantic deficits and behavioural abnormalities that occur in the wake of bilateral inferolateral and predominantly left-sided anterior temporal lobe atrophy. The temporal poles have been shown to be involved in theory of mind, namely the ability to ascribe cognitive and affective mental states to others that regulates social interactions by predicting and interpreting human behaviour. However, very few studies have examined theory of mind in semantic dementia. In this study, we investigated both cognitive and affective theory of mind in a group of patients with semantic dementia, using separate objective and subjective assessment tasks. Results provided objective evidence of an impact of semantic dementia on cognitive and affective theory of mind, consistent with the patients' atrophy in the left temporal lobe and hypometabolism in the temporal lobes and the medial frontal cortex. However, the subjective assessment of theory of mind suggested that awareness of the affective but not cognitive theory of mind deficit persists into the moderate stage of the disease.

    New determinants of quality of life in schizophrenia need to be identified. As sensory gating deficit is core impairment in schizophrenia, the present study hypothesized that sensory gating deficit is a determinant of impaired quality of life in schizophrenia. This study therefore investigated the relationship between sensory gating deficit and quality of life in patients with schizophrenia after adjusting for key confounding factors. Sensory gating was assessed with the auditory event-related potential method by measuring P50 amplitude changes in a double-click conditioning-testing procedure, perceptual impairments related to sensory gating deficit was assessed with the SGI questionnaire and quality of life was assessed with the SQoL 18 questionnaire in 39 patients with schizophrenia. Patients with sensory gating deficit (n=14) had a lower subjective quality of life on the psychological well-being dimension evaluated with SQoL 18 questionnaire (p=0.008) compared to those without it (n=25). This result remained significant (B=-0.45, Wald=4.84, p=0.02) after taking into account 7 potential confounding factors (gender, age, level of education, duration of disorder, positive symptoms, depressive symptoms and anxiety symptoms). Poorer psychological well-being was related to a higher score on the SGI (rho=-0.40, p=0.01), in particular on the Distractibility dimension (rho=-0.47, p=0.001). These findings suggest that sensory gating deficit may be a determinant of impaired quality of life in schizophrenia. Further studies are needed to address the causal relationship between sensory gating deficit, perceptual impairments, attentional deficit and impaired quality of life in schizophrenia in order to act more efficiently on the quality of life of patients with this disorder.

    Full Text Available There are very few published reports on the causes of chronic kidney disease (CKD in Egyptian children. We reviewed the records of 1018 (males 56.7%, age ranged from 1 to 19 years Egyptian patients suffering from CKD and followed-up at the pediatric nephrology units (outpatient clinics and dialysis units of 11 universities over a period of two years. The mean of the estimated glomerular filtration rate was 12.5 mL/min/1.73 m 2 . Children with CKD stage I and stage II comprised 4.4% of the studied group, while those with stage III, IV and V comprised 19.7%, 18.3% and 57.6%, respectively. The most common single cause of CKD was obstructive uropathy (21.7%, followed by primary glomerulonephritis (15.3%, reflux/urinary tract infection (14.6%, aplasia/hypoplasia (9.8% and familial/metabolic diseases (6.8%; unknown causes accounted for 20.6% of the cases. Of the 587 patients who had reached end-stage renal disease, 93.5% was treated with hemodialysis and only 6.5% were treated with peritoneal dialysis.

    Antiviral therapy for HCV infection has been validated in randomized controlled clinical trials, but its value in the real world is less well studied. There is relatively little data on real-world responses to interferon-based therapies for patients with genotype 4 infection. We aimed to examine experience with large-scale access to antiviral therapy in chronic HCV in a real-life clinical setting in Egypt. Detailed pretreatment data of 6198 IFN-naïve chronic HCV patients who had received PEG-IFN/RBV therapy at Cairo-Fatemic Hospital, Egypt, between 2009 and 2012 were obtained from the HCV database. At week 12, 95.7% of patients had undetectable HCV RNA, and by week 24 and 48, breakthrough was 6% and 4%, respectively. However, 43.7% of patients discontinued treatment prematurely, and intent to treat end of treatment response was 44.6% (79.3% per protocol). Sustai-ned response data were available from only 1281 patients and was 84.9%. Haematological abnormalities were comparable in patients who did or did not comply with therapy. This is the first real-world, large-scale experience of antiviral therapy in chronic HCV in Egypt. Suboptimal response in HCV predominantly genotype 4 was mainly driven by noncompliance as well as gaps in the healthcare system leading to treatment discontinuation. These results need to be considered in the era of all oral antiviral regimes.

    Full Text Available Complete denture wearers often find it difficult to accept a new denture. Personality traits are among the factors that possibly affect patient satisfaction with a complete denture. Our aim was to investigate the influence of patients’ personality on satisfaction with their present denture and after an increase in the occlusal vertical dimension (OVD. Sixty edentulous patients with complete dentures (22 men and 38 women, mean age 66 years, and range 50–75 years participated in the study. The age of their complete dentures ranged from 5 to 16 years. Patients’ personalities were evaluated using the Arabic version of the Eysenck Personality Questionnaire. Their satisfaction with their dentures before and after restoration of the OVD and relining of the mandibular denture was evaluated using two questionnaires (I and II, Patients with a high score of neuroticism were less satisfied with their original dentures and after relining and an increase of OVD compared with patients with an average score in that trait. The personality trait of psychoticism was significant to patients’ acceptance of an increase in OVD; that is, patients with a high score were less satisfied with their dentures after increase of OVD than patients with an average score. It is concluded that personality traits affect patients’ acceptance of their complete dentures.

    Type 2 diabetes mellitus patients (T2D) have elevated risk of stroke, suggesting that cerebrovascular function is impaired. Herein, we examined dynamic cerebral autoregulation (CA) at rest and during exercise in T2D patients and determined whether underlying systemic oxidative stress is associated with impairments in CA. Middle cerebral artery blood velocity and arterial blood pressure (BP) were measured at rest and during 2-min bouts of low- and high-intensity isometric handgrip performed at 20% and 40% maximum voluntary contraction, respectively, in seven normotensive and eight hypertensive T2D patients and eight healthy controls. Dynamic CA was estimated using the rate of regulation (RoR). Total reactive oxygen species (ROS) and superoxide levels were measured at rest. There were no differences in RoR at rest or during exercise between normotensive and hypertensive T2D patients. However, when compared with controls, T2D patients exhibited lower RoR at rest and during low-intensity handgrip indicating impaired dynamic CA. Moreover, the RoR was further reduced by 29 ± 4% during high-intensity handgrip in T2D patients (0.307 ± 0.012/s rest vs. 0.220 ± 0.014/s high intensity; P < 0.01), although well maintained in controls. T2D patients demonstrated greater baseline total ROS and superoxide compared with controls, both of which were negatively related to RoR during handgrip (e.g., total ROS: r = -0.71, P < 0.05; 40% maximum voluntary contraction). Collectively, these data demonstrate impaired dynamic CA at rest and during isometric handgrip in T2D patients, which may be, in part, related to greater underlying systemic oxidative stress. Additionally, dynamic CA is blunted further with high intensity isometric contractions potentially placing T2D patients at greater risk for cerebral events during such activities.

    Pesticides have contributed to dramatic increases in crop yields and in the quantity and variety of the diet. Also, they have helped to limit the spread of certain diseases. But pesticides have harmful effects; they can cause injury to human health as well as to the environment. The range of these adverse health effects includes acute and persistent injury to the nervous system, lung damage, injury to the reproductive organs, dysfunction of the immune and endocrine systems, birth defects, and cancer. Problems associated with pesticide hazards to man and the environment are not confined to the developing countries. Developed nations have already suffered these problems, and still facing some problems in certain locations. For many reasons, the severity of pesticide hazards is much pronounced in Third World Countries. A number of long persistent organochlorines and highly toxic organophosphates, which have been banned or severely restricted, are still marketed and used in many developing countries. The misuse of pesticides by concerned individuals, in addition to lack of or weak national controlling plans are behind the outbreak of adverse effects in developing countries. Since about 25 years, the use of DDT and many other organochlorine pesticides in Egyptian agriculture has been banned. However, these long persistent compounds are still detectable in many different types of environmental samples (e.g., water, fish, sediment, vegetables, fruits, milk, foodstuffs, etc.). Large number of compounds known as "extremely hazardous", "highly hazardous", "probable human carcinogenic", and "possible human carcinogenic", are listed among the pesticides registered and recommended for use in Egypt during the season of 2001/2002. The present article deals with: trends and patterns of pesticide use, impact of pesticides on human health, factors contributing to pesticide risks, environmental impacts of pesticides, and bioaccumulation of pesticide residues in food; giving special

    2003-01-01

    In his paper, "The Relevance of Rawls' Principle of Justice for Research on Cognitively Impaired Patients" (Theoretical Medicine and Bioethics 23 (2002): 45-53), Giovanni Maio has developed a thought-provoking argument for the permissibility of non-therapeutic research on cognitively impaired patients. Maio argues that his conclusion follows from the acceptance of John Rawls's principles of justice, specifically, Rawls's "liberty principle". Maio has misinterpreted Rawls's "liberty principle"--correctly interpreted it does not support non-therapeutic research on cognitively impaired patients. Three other 'Rawlsian' arguments are suggested by Maio's discussion--two "self-respect" arguments and a "presumed consent" argument--but none of them are convincing. However, an alternative argument developed from Rawls's discussion of "justice in health care" in his most recent book, Justice as Fairness: A Restatement, may justify certain kinds of non-therapeutic research on some cognitively impaired patients in special circumstances. We should not expect anything more permissive from a liberal theory of justice.

    Evidences supporting the association between H. pylori infection and chronic cholecystitis could be found by using direct culture or staining of H. pylori in gallbladder tissues as well as indirect techniques. Stool antigen test has been widely used due to its noninvasive nature. Various stool antigen tests were developed to detect H. pylori using an enzyme immunoassay (EIA) based on monoclonal or polyclonal antibodies This study evaluated the frequency of H. pylori antigen in stool samples of patients with chronic calcular cholecystitis as regard gall bladder histopathological changes. Fifty patients were included presented with symptomatic qholecystolithiasis recruited from the outpatient clinic of National Hepatology and Tropical Medicine Research Institute during 2014-2015. Full history and clinical examination and abdominal ultrasonography were performed. Stool samples were collected, prepared and examined for detection of H. pylori antigen. Cholecystectomy was done for all patients; 45 patients (90%) by laparoscopic Cholecystectomy and 5 patients (10%) by open surgery and removed gallbladders were submitted to pathology department for detection of H. pylori in tissue under microscope using Giemsa stain. The results showed that (82%) were females with mean age (42.6 +/- 1 years). The mean BMI was (29 + 7.2) H. pylori-specific antigen in stool samples was detected in 40% of patients and 38% were detected in patients; tissue, with significant correlation between H. pylori-specific antigen in stool and in tissue. Histopathological pictures infection in tissue were 68.4% mucosal erosions, 63.2% mucosal atrophy, 57.9% mucosal hyperplasia, 26.3% metaplasia, 42.1% musculosa hypertrophy, 26.3% fibrosis, but lymphoid aggregates were in 42.1% of cases.

    Full Text Available We analyzed cytokine responses against latent and lytic Epstein-Barr virus (EBV antigens in systemic lupus erythematosus (SLE patients and healthy controls (HCs to obtain an overview of the distinctive immune regulatory response in SLE patients and to expand the previously determined impaired EBV-directed T-cell response. The concentrations of 14 cytokines (IL2, IL4, IL5, IL6, IL10, IL12, IL17, IL18, IL1β, IFNγ, TNFα, TNFβ, TGFβ, and GM-CSF were quantified upon stimulation of whole blood with latent state antigen EBNA1, lytic cycle antigen EBV-EA/D, and the superantigen SEB. To avoid results affected by lack of lymphocytes, we focused on SLE patients with normal levels. Decreased induction of IL12, IFNγ, IL17, and IL6 upon EBNA1 stimulation and that of IFNγ, IL6, TNFβ, IL1β, and GM-CSF upon EBV-EA/D stimulation were detected in SLE patients compared to HCs. IFNγ responses, especially, were shown to be reduced. Induction of several cytokines was furthermore impaired in SLE patients upon SEB stimulation, but no difference was observed in basic levels. Results substantiate the previously proposed impaired regulation of the immune response against latent and lytic cycle EBV infection in SLE patients without lymphopenia. Furthermore, results indicate general dysfunction of leukocytes and their cytokine regulations in SLE patients.

    2015-08-01

    Although it has been proposed that visuospatial working memory may be impaired in Bálint syndrome patients, neither a systematic study concerning this proposal nor a comparison with patients having right-parietal damage has been made. Visuospatial working memory was assessed for six Bálint syndrome patients and members of two control groups-one composed of individuals with right-parietal damage (n = 15) and a second of age- and gender-matched healthy individuals (n = 26). We placed special emphasis on patients with a mild form of Bálint syndrome who can judge positional relationships between two objects. First, the participants were subjected to delayed visuospatial matching tasks. Next, their visuospatial-temporal integration abilities were assessed using a shape-from-moving-dots task. Visuospatial working memory was impaired for Bálint syndrome patients compared with controls according to the results of the tests. The differences between the Bálint syndrome and control subjects remained when only data for patients with the mild form of Bálint syndrome were included. We conclude that visuospatial working memory may be severely impaired in Bálint syndrome patients and, therefore, might influence their inability to properly execute movements and behaviours associated with daily living.

    Full Text Available Congenital cataracts, facial dysmorphism, neuropathy (CCFDN syndrome is a complex autosomal recessive multisystem disorder. The aim of the current study is to evaluate the degree of cognitive impairment in a cohort of 22 CCFDN patients and its correlation with patients’ age, motor disability, ataxia, and neuroimaging changes. Twenty-two patients with genetically confirmed diagnosis of CCFDN underwent a detailed neurological examination. Verbal and nonverbal intelligence, memory, executive functions, and verbal fluency wеre assessed in all the patients aged 4 to 47 years. Brain magnetic resonance imaging was performed in 20 affected patients. Eighteen affected were classified as having mild intellectual deficit, whereas 4 had borderline intelligence. In all psychometric tests, evaluating different cognitive domains, CCFDN patients had statistically significant lower scores when compared to the healthy control group. All cognitive domains seemed equally affected. The main abnormalities on brain MRI found in 19/20 patients included diffuse cerebral atrophy, enlargement of the lateral ventricles, and focal lesions in the subcortical white matter, different in number and size, consistent with demyelination more pronounced in the older CCFDN patients. The correlation analysis of the structural brain changes and the cognitive impairment found a statistically significant correlation only between the impairment of short-term verbal memory and the MRI changes.

  12. Visuomotor performance based on peripheral vision is impaired in the visual form agnostic patient DF.

    The perception-action model states that visual information is processed in different cortical areas depending on the purpose for which the information is acquired. Specifically, it was suggested that the ventral stream mediates visual perception, whereas the dorsal stream primarily processes visual information for the guidance of actions (Goodale & Milner, 1992). Evidence for the model comes from patient studies showing that patients with ventral stream damage (visual form agnosia) and patients with dorsal stream damage (optic ataxia) show divergent performance in action and perception tasks. Whereas DF, a patient suffering from visual form agnosia, was found to perform well in visuomotor tasks despite her inability to use vision for perceptual tasks, patients with optic ataxia show usually the opposite pattern, i.e. good perception but impaired visuomotor control. The finding that both disorders seem to provoke a mirror-reversed pattern of spared and impaired visual functions, led to the belief that optic ataxia and visual form agnosia can be considered as complementary disorders. However, the visuomotor performance of patients with optic ataxia is typically only impaired when they are tested in visual periphery while being often preserved when tested in central vision. Here, we show that DF's visuomotor performance is also only preserved when the target is presented centrally. Her reaching and grasping movements to targets in peripheral vision are abnormal. Our findings indicate that DF's visuomotor performance is quite similar to the visuomotor performance of patients with optic ataxia which undermines previous suggestions that the two disorders form a double-dissociation.

    Gaucher disease (GD) is characterized by glucocerebroside (GC) accumulation due to defective activity of the glucocerebrosidase (GlcCerase) enzyme. Monocytes and macrophages exhibit the highest GlcCerase activity and are most prominently affected by GC engorgement. As GD patients tend to exert various immune system-related changes, this study was designed to investigate potential effects of monocyte dysfunction on these alterations. Monocytes were isolated from peripheral blood mononuclear cells (PBMCs) of untreated GD patients and healthy volunteers. Monocyte migration capacity towards SDF1α was assessed. The GD patients exhibited reduced numbers of monocytes and decreased capability of SDF1α-dependent monocyte migration. Evaluation of CXCR4, the SDF1α receptor, revealed reduced expression of surface CXCR4 on GD-derived monocytes, despite similar CXCR4 mRNA transcript levels in the monocytes of healthy volunteers and GD patients. Reduction of surface CXCR4 was accompanied by increased intracellular CXCR4 levels in patient monocytes. This elevated intracellular CXCR4 might reflect significantly increased SDF1α concentrations characterizing patients' serum and the lysosomal impairment of GD, resulting in decreased degradation of CXCR4. Different distributions of CXCR4 expression observed in the two groups explain impaired SDF1α-dependent monocyte migration. Reduced numbers and impaired migration capacity of GD-derived monocytes could contribute to abnormal inflammation and GD-associated immune alterations seen in these patients.

    Full Text Available To investigate potential associations between carotid artery stenosis and cognitive impairment among patients with acute ischemic stroke and to provide important clinical implications. We measured the degree of carotid artery stenosis and recorded the Mini-Mental State Examination score (MMSE at admission in 3116 acute ischemic stroke patients. The association between carotid stenosis and cognitive impairment assessed by MMSE was tested using multivariate regression analysis. Other clinical variables of interest were also studied. After adjusting for age, gender, education level, marriage, alcohol use, tobacco use, physical activity, hypertension, diabetes, hypercholesterolemia, atrial fibrillation, myocardial infarction and NIHSS (National Institutes of Health Stroke Scale score, we found that participants with high-grade stenosis of the carotid artery had a higher likelihood of cognitive impairment compared to those without carotid artery stenosis (OR = 1.49, 95%CI: 1.05-2.11, p<0.001. Left common carotid artery stenosis was associated with cognitive impairment in the univariate analysis, although this effect did not persist after adjustment for the NIHSS score. Cognitive impairment was associated with high-grade stenosis of the right carotid artery.

    To investigate potential associations between carotid artery stenosis and cognitive impairment among patients with acute ischemic stroke and to provide important clinical implications. We measured the degree of carotid artery stenosis and recorded the Mini-Mental State Examination score (MMSE) at admission in 3116 acute ischemic stroke patients. The association between carotid stenosis and cognitive impairment assessed by MMSE was tested using multivariate regression analysis. Other clinical variables of interest were also studied. After adjusting for age, gender, education level, marriage, alcohol use, tobacco use, physical activity, hypertension, diabetes, hypercholesterolemia, atrial fibrillation, myocardial infarction and NIHSS (National Institutes of Health Stroke Scale) score, we found that participants with high-grade stenosis of the carotid artery had a higher likelihood of cognitive impairment compared to those without carotid artery stenosis (OR = 1.49, 95%CI: 1.05–2.11, p<0.001). Left common carotid artery stenosis was associated with cognitive impairment in the univariate analysis, although this effect did not persist after adjustment for the NIHSS score. Cognitive impairment was associated with high-grade stenosis of the right carotid artery. PMID:26751070

    BACKGROUND: Many studies have suggested that one possible etiology of mild cognitive impairment is small vessel cerebrovascular disease, which is associated with small subcortical infarcts and white matter abnormalities. These white matter changes have been detected as white matter hyperintensity (WMH) using magnetic resonance imaging. WMH may be associated with frontal lobe dysfunction. OBJECTIVE: To examine white matter changes in mild cognitive impairment patients of different subtypes, and to evaluate the correlation between white matter changes and neuropsychological characteristics, demographic information, vascular risk factors, and mild cognitive impairment subtypes. DESIGN, TIME AND SETTING: The neurophysiological, comparison study was performed at the Department of Neurology Memory Clinic, Ulsan University Hospital, South Korea, between March 2007 and March 2008.PARTICIPANTS: Out of a total of 83 subjects with clinically diagnosed mild cognitive impairment at the out-patient clinic, 3 subjects with severe WMH were excluded. A total of 80 subjects were included in this study. No patients suffered from cognitive impairment induced by neurological diseases, mental disorders, or somatic diseases. In accordance with magnetic resonance imaging results, the patients were assigned to two subtypes: 56 subjects without WMH and 24 subjects with WMH. METHODS: All patients were subjected to a standard neuropsychological battery using the Korean version of the Mini-Mental State Examination, Clinical Dementia Rating, and comprehensive Seoul Neuropsychological Screening Battery. The Clinical Dementia Rating reflected general cognitive function of patients. Results from the Seoul Neuropsychological Screening Battery reflected attention, language function, visuospatial function, verbal memory, nonverbal memory, long-term memory, and frontal/executive function. Magnetic resonance imaging was used to map changes in the brain. MAIN OUTCOME MEASURES: The association between

    A variety of studies demonstrated that some forms of memory for music are spared in dementia, but only few studies have investigated patients with early stages of dementia. In this pilot-study we tested working memory for music in patients with mild cognitive impairment (MCI) and early stage Alzheimer's disease (AD) with a newly created test. The test probed working memory using 7 gradually elongated tone-lines and 6 chords which were each followed by 3 similar items and 1 identical item. The participants of the study, namely 10 patients with MCI, 10 patients with early stage AD and 23 healthy subjects were instructed to select the identical tone-line or chord. Subjects with MCI and early AD showed significantly reduced performance than controls in most of the presented tasks. In recognizing chords MCI- participants surprisingly showed an unimpaired performance. The gradual increase of the impairment during the preclinical phase of AD seems to spare this special ability in MCI.

    The present study was aimed at evaluating the effective radiation dose in patients submitted to PET/CT for the diagnosis of mild cognitive impairment. TLD-100 detectors inserted into an Alderson Rando® anthropomorphic phantom were utilized to measure the absorbed dose coming from the CT imaging modality. The anthropomorphic phantoms (male and female adult versions) were submitted to the same technical protocols for patients' images acquisition. The absorbed dose resulting from the radiopharmaceutical injection was estimated by means of the model proposed by the ICRP publication 106. The effective dose in patients submitted to this diagnostic technique was approximately (5.34 ± 1.99) mSv. Optimized protocols for calculation of radioactive activity injected into patients submitted to this diagnostic technique might contribute to reduce the effective radiation dose resulting from PET/CT in the diagnosis of mild cognitive impairment.

    Summary Semantic dementia is characterized by semantic deficits and behavioural abnormalities which occur in the wake of bilateral inferolateral and predominantly left-sided anterior temporal lobe atrophy. The temporal poles have been shown to be involved in theory of mind, namely the ability to ascribe cognitive and affective mental states to others that regulates social interactions by predicting and interpreting human behaviour. However, very few studies have examined theory of mind in semantic dementia. In this study, we investigated both cognitive and affective theory of mind in a group of semantic dementia patients, using separate objective and subjective assessment tasks. Results provided objective evidence of an impact of semantic dementia on cognitive and affective theory of mind, consistent with the patients’ atrophy in the left temporal lobe and hypometabolism in the temporal lobes and the medial frontal cortex. However, the subjective assessment of theory of mind suggested that awareness of the affective but not cognitive theory of mind deficit persists into the moderate stage of the disease. PMID:22232593

    The pathogenesis of acute myeloid leukemia (AML) involves the cooperation of mutations promoting proliferation/survival and those impairing differentiation. Point mutations of the N-RAS gene are the most frequent somatic mutations causing aberrant signal-transduction in acute myeloid leukemia (AML). The aim of the present work is to study the frequency and prognostic significance of N-RAS gene mutations (N-RASmut) in de novo Egyptian adult AML. Bone marrow specimens from 150 patients with de novo acute myeloid leukemia and controls were analyzed by genomic PCR-SSCP at codons 12, 13 (exon 1), and 61 (exon 2) for N-RAS mutations. In 12.7% (19/150) AML cases, N-RAS gene mutations were found and were observed more frequently in the FAB subtype M4eo (P = 0.028) and with codon 12, 13 (14 of 19; 73.7%). Patients with N-RAS mutation had a significant lower peripheral and marrow blasts (P = 0.004, P = 0.03) and clinical outcome did not improve more than in patients without mutation. In patients with N-RAS gene mutation vs. those without, complete remission rate was (63.2% vs. 56.5%; P = 0.46), resistant disease (15.8% vs. 23.6%; P = 0.51), three years overall survival (44% vs 42%; P= 0.85) and disease free survival (42.1% vs. 38.9%, P = 0.74). Multivariate analysis showed that age was the strongest unfavorable factor for overall survival (relative risk [RR], 1.9; P = 0.002), followed by cytogenetics (P = 0.004). FAB types, N-RAS mutation and leukocytosis were the least important. In conclusion, the frequency and spectrum of N-RAS gene mutation differ between biologically distinct subtypes of AML but do not significantly influence prognosis and clinical outcome in patients with AML.

    Full Text Available Objective: Rheumatoid arthritis (RA differs depending on the age of disease onset. The differences between EORA and YORA are important because they have clinical and therapeutic implications. Method: 1185 patients were ranked after classification according to age at onset of the disease into YORA I (16–40 years, YORA II (41–60 years and EORA .60 years. All patients groups were compared, based on disease duration, disease activity, severity parameters and drug history. Results: YORA I included 298 patients, 28.85% were males, with mean age of 29.4 ± 6 years and disease duration 4 ± 3.3 y, YORA II included 539 patients, 33.77% males, age 49.7 ± 6.1 y and disease duration 6.5 ± 5.6 y. EORA included 348 RA patients 40.5% males, age 67.1 ± 6.6 y, disease duration 9.95 ± 7.2 y. Activity was increased in EORA compared to YORA I and YORA II, while severity decreased in EORA. ESR, CRP and degree of anemia were higher in EORA. RF titer was higher in YORA. Small joints of the hands and feet were more involved in YORA, while, large joints in EORA. Rheumatoid nodules were increased in YORA I than EORA P = 0.04. Polymyalgia rheumatica was exclusively present in EORA group 25 patients 7.2%. Methotrexate was used in both YORA and EORA, with a higher mean of dosage in YORA than EORA. Multiple DMARDs in EORA was 57.9%, and biologics in 0.8% was which was significantly lower compared with YORA I, 86.3% and 1.7%, with P = 0.001. Conclusion: EORA has more active and less disabling and affects more males than YORA. The use of biologic therapy and combination DMARD therapy was less in EORA.

    Symptoms and subsequent functional impairment have been associated with the biological processes of disease, including the interaction between disease and treatment in a measurement model of symptoms. However, hitherto cluster analysis has primarily focused on symptoms. This study among patients within 100 days of diagnosis with advanced cancer explored whether self-reported physical symptoms and functional impairments formed clusters at the time of diagnosis. We applied cluster analysis to self-reported symptoms and activities of daily living of 111 patients newly diagnosed with advanced gastrointestinal (GI), gynecological, head and neck, and lung cancers. Based on content expert evaluations, the best techniques and variables were identified, yielding the best solution. The best cluster solution used a K-means algorithm and cosine similarity and yielded five clusters of physical as well as emotional symptoms and functional impairments. Cancer site formed the predominant organizing principle of composition for each cluster. The top five symptoms and functional impairments in each cluster were Cluster 1 (GI): outlook, insomnia, appearance, concentration, and eating/feeding; Cluster 2 (GI): appetite, bowel, insomnia, eating/feeding, and appearance; Cluster 3 (gynecological): nausea, insomnia, eating/feeding, concentration, and pain; Cluster 4 (head and neck): dressing, eating/feeding, bathing, toileting, and walking; and Cluster 5 (lung): cough, walking, eating/feeding, breathing, and insomnia. Functional impairments in patients newly diagnosed with late-stage cancers behave as symptoms during the diagnostic phase. Health care providers need to expand their assessments to include both symptoms and functional impairments. Early recognition of functional changes may accelerate diagnosis at an earlier cancer stage. Copyright © 2013 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc. All rights reserved.

    2002-01-01

    The aim of this study was to test and select one or more highly sensitive, specific and environmentally successful Egyptian bioindicator plants for ozone (O3). For that purpose more than 30 Egyptian species and cultivars were subjected to extensive screening studies under controlled environmental and pollutant exposure conditions to mimic the Egyptian environmental conditions and O3 levels in urban and rural sites. Four plant species were found to be more sensitive to O3 than the universally used O3-bioindicator, tobacco Bel W3, under the Egyptian environmental conditions used. These plant species, jute (Corchorus olitorius c.v. local), clover (Trifolium alexandrinum L. c.v. Masry), garden rocket (Eruca sativa c.v. local) and alfalfa (Medicago sativa L. c.v. local), ranked in order of decreasing sensitivity, exhibited typical O3 injury symptoms faster and at lower 03 concentrations than Bel W3. Three variables were tested in search of a reliable tool for the diagnosis and prediction of O3 response prior to the appearance of visible foliar symptoms: pigment degradation, stomatal conductance (g(s)) and net photosynthetic CO2 assimilation (Pnet). Pigment degradation was found to be unreliable in predicting species sensitivity to O3. Evidence supporting stomatal conductance involvement in 03 tolerance was found only in tolerant species. A good correlation was found between g(s), restriction of O3 and CO2 influx into the mesophyll tissues, and Pnet. Changes in Pnet seemed to depend largely on fluctuations in g(s).

    Egypt is famously known for its Nile and pyramids, yet not many people know that Egypt made possible the origin of the anatomical sciences. Several ancient papyri guide us through the Egyptians' exploration of the human body and how they applied anatomical knowledge to clinical medicine to the best of their knowledge. It is through records, such as the Edwin Smith, Ebers, and Kahun papyri and other literature detailing the work of the Egyptian embalmers, physicians, and Greek anatomists, that we are able to take a glimpse into the evolution of the anatomical sciences from 3000 B.C. to 250 B.C. It is through the Egyptian embalmer that we were able to learn of some of the first interactions with human organs and their detailed observation. The Egyptian physician's knowledge, being transcribed into the Ebers and Edwin Smith papyri, enabled future physicians to seek reference to common ailments for diagnosing and treating a variety of conditions ranging from head injuries to procedures, such as trans-sphenoidal surgery. In Alexandria, Herophilus, and Erasistratus made substantial contributions to the anatomical sciences by beginning the practice of human dissection. For instance, Herophilus described the anatomy of the heart valves along with Erasistratus who demonstrated how blood was prevented from flowing retrograde under normal conditions. Hence, from various records, we are able to unravel how Egypt paved the road for study of the anatomical sciences.

    2014-12-01

    Full Text Available Background: The nasal index determination is one of the most commonly used anthropometric parameters in classifying human races. There are few reports in medical literature concerning nasal index that specifically address particular Egyptian populations. The objective of this study was to determine the normal parameters of external nose (width, height and nasal index in Egyptians. Methods: The study was conducted randomly on healthy Egyptian subjects of both sexes. Nasal height and width were measured using vernier caliper. Then, nasal index was determined for each subject. The obtained data were subjected to statistical analysis. Results: A total of 290 subjects, 144 males and 146 females, aged 1 month– 65 years, were enrolled in the study. The study showed the existence of sexual dimorphism in nasal morphology, appearing after the age 20 years. The mean nasal index in the investigated adults was 68.01; in males and females was 71.46 and 64.56, respectively. Conclusions: The dominant nasal type in Egyptians was in-between mesorrhine "medium" and leptorrhine "narrow" nose. Forensic and anthropological research, as well as cosmetic and reconstructive surgery may benefit from age- and sex- based data of the study.

    In a multicenter setting, we applied voxel-based methods to different structural MR imaging modalities to define the relative contributions of focal lesions, normal-appearing white matter (NAWM), and gray matter (GM) damage and their regional distribution to cognitive deficits as well as impairment of specific cognitive domains in multiple sclerosis (MS) patients. Approval of the institutional review boards was obtained, together with written informed consent from all participants. Standardized neuropsychological assessment and conventional, diffusion tensor and volumetric brain MRI sequences were collected from 61 relapsing-remitting MS patients and 61 healthy controls (HC) from seven centers. Patients with ≥2 abnormal tests were considered cognitively impaired (CI). The distribution of focal lesions, GM and WM atrophy, and microstructural WM damage were assessed using voxel-wise approaches. A random forest analysis identified the best imaging predictors of global cognitive impairment and deficits of specific cognitive domains. Twenty-three (38%) MS patients were CI. Compared with cognitively preserved (CP), CI MS patients had GM atrophy of the left thalamus, right hippocampus and parietal regions. They also showed atrophy of several WM tracts, mainly located in posterior brain regions and widespread WM diffusivity abnormalities. WM diffusivity abnormalities in cognitive-relevant WM tracts followed by atrophy of cognitive-relevant GM regions explained global cognitive impairment. Variable patterns of NAWM and GM damage were associated with deficits in selected cognitive domains. Structural, multiparametric, voxel-wise MRI approaches are feasible in a multicenter setting. The combination of different imaging modalities is needed to assess and monitor cognitive impairment in MS.

  13. Memory concerns, memory performance and risk of dementia in patients with mild cognitive impairment.

    Steffen Wolfsgruber

    Full Text Available Concerns about worsening memory ("memory concerns"; MC and impairment in memory performance are both predictors of Alzheimer's dementia (AD. The relationship of both in dementia prediction at the pre-dementia disease stage, however, is not well explored. Refined understanding of the contribution of both MC and memory performance in dementia prediction is crucial for defining at-risk populations. We examined the risk of incident AD by MC and memory performance in patients with mild cognitive impairment (MCI.We analyzed data of 417 MCI patients from a longitudinal multicenter observational study. Patients were classified based on presence (n = 305 vs. absence (n = 112 of MC. Risk of incident AD was estimated with Cox Proportional-Hazards regression models.Risk of incident AD was increased by MC (HR = 2.55, 95%CI: 1.33-4.89, lower memory performance (HR = 0.63, 95%CI: 0.56-0.71 and ApoE4-genotype (HR = 1.89, 95%CI: 1.18-3.02. An interaction effect between MC and memory performance was observed. The predictive power of MC was greatest for patients with very mild memory impairment and decreased with increasing memory impairment.Our data suggest that the power of MC as a predictor of future dementia at the MCI stage varies with the patients' level of cognitive impairment. While MC are predictive at early stage MCI, their predictive value at more advanced stages of MCI is reduced. This suggests that loss of insight related to AD may occur at the late stage of MCI.

    Conclusion: Our data suggest that increased serum IL-22 may contribute to the pathogenesis of SLE. Its elevated serum level allows discrimination between patients with different clinical and laboratory measures and indicates the potential of IL-22 as an additional tool for assessment of activity in SLE. IL22 in serum seems to be a significant index reflecting skin and renal involvement in SLE.

    Full Text Available Matrix metalloproteinases (MMPs, a family of proteolytic enzymes produced by both stromal and tumor cells, appear to have a key role in the events leading to local invasion and metastasis by malignant neoplasms. In the present study, we evaluated the role of MMP-2, squamous cell carcinoma antigen (SCCA, and tissue polypeptide – specific antigen (TPS in cervical neoplasia. Using Western blotting and enzyme immunoassay (EIA, we analyzed 50 patients with cervical carcinoma (CC and 25 normal controls for expression of MMP-2 in tissue cell lysates. We also quantified SCCA and TPS with microparticle immunoassay and EIA, respectively. The results were correlated with human papilloma virus (HPV infection, clinicopathological findings, and disease outcome. The cutoff point for each marker was estimated from receiver operating characteristic curves. Logistic regression analysis was performed to estimate the odds ratio (OR and 95% confidence interval (CI for each marker. MMP-2, SCCA, and TPS protein expression were significantly higher in patients with CC than in normal controls. While TPS was the best marker for discriminating between patients and controls, MMP-2 was associated with an advanced tumor stage (OR, 13.9 [95% CI, 1.4-133.9] and poor histological grade (OR, 10.2 [95% CI, 1.7-60.5]. Moreover, independent of the effect of an advanced CC stage and grade, the patients' age, and the presence of HPV infection, MMP-2 was considered a strong predictor for CC recurrence (OR, 8.1 [95% CI, 1.3- 49.1]. Tissue markers may be used to select high-risk patients for early detection of and adjuvant therapy for recurrence. Our MMP-2 findings are particularly relevant to the development of protease inhibitors as a new cancer therapy approach.

  19. Ancient Egyptian Medicine: A Systematic Review

    2015-12-01

    Full Text Available Our present day knowledge in the area of medicine in Ancient Egypt has been severally sourced from medical papyri several of which have been deduced and analyzed by different scholars. For educational purposes it is always imperative to consult different literature or sources in the teaching of ancient Egypt and medicine in particular. To avoid subjectivity the author has found the need to re-engage the efforts made by several scholars in adducing evidences from medical papyri. In the quest to re-engage the efforts of earlier writers and commentaries on the medical papyri, we are afforded the opportunity to be informed about the need to ask further questions to enable us to construct or reconstruct both past and modern views on ancient Egyptian medical knowledge. It is this vocation the author sought to pursue in the interim, through a preliminary review, to highlight, comment and reinvigorate in the reader or researcher the need for a continuous engagement of some pertinent documentary sources on Ancient Egyptian medical knowledge for educational and research purposes. The study is based on qualitative review of published literature. The selection of those articles as sources was based on the focus of the review, in order to purposively select and comment on articles that were published based either on information from a medical papyrus or focused on medical specialization among the ancient Egyptians as well as ancient Egyptian knowledge on diseases and medicine. It was found that the Egyptians developed relatively sophisticated medical practices covering significant medical fields such as herbal medicine, gynecology and obstetrics, anatomy and physiology, mummification and even the preliminary form of surgery. These practices, perhaps, were developed as remedies for the prevailing diseases and the accidents that might have occurred during the construction of their giant pyramids. It must be stated that they were not without flaws. Also, the

    Patients on sick leave due to work-related stress often present with cognitive impairments. The aim of this prospective cohort study was to examine the long-term consequences of prolonged work-related stress in terms of cognitive functioning one year after initial professional care seeking. We tested a group of patients with work-related stress with a comprehensive neuropsychological test battery at two occasions, one year apart. At both time points, we compared the performance of patients with healthy controls matched pairwise on sex, age and length of education. This paper presents the results from the one-year follow-up. When adjusting for practice effects, patients improved on measures of prospective memory and processing speed. However, patients continued to perform worse than controls on all tests, though only half of the comparisons reached statistical significance. The effect sizes of the differences between the two groups at one-year follow-up were small to medium. In conclusion, former patients with prolonged work-related stress improved, but they continued to perform worse than controls after one year. In the acute phase, the largest impairments were related to executive function and mental speed but at follow-up memory impairments also became apparent.

    Compared with a group of age matched controls, patients with Parkinson's disease scored significantly lower in testing for ideomotor apraxia. Imitation of movement sequences was affected more severely than performance of single movements. The degree of impairment was not related to severity of motor disability, but correlated strongly with the results of tests that measured visuospatial and visuoperceptive abilities. It is suggested that defective encoding and central processing of visuospatial information impairs memory for movement which is necessary for correct imitation of movements. Enhanced vulnerability to interference between successively presented items may cause further deterioration of performance in the copying of movement sequences. PMID:3794732

    Nerve function impairment (NFI) in leprosy may occur and progress despite multidrug therapy alone or in combination with corticosteroids. We observed improvement in neuritis when minocycline was administered in patients with type 2 lepra reaction. This prompted us to investigate the role of minocycline in recent onset NFI, especially in corticosteroid unresponsive leprosy patients. Leprosy patients with recent onset clinical NFI (leprosy patients. However, larger and long term comparative trials are needed to validate the efficacy of minocycline in leprosy neuropathy. © 2016 Wiley Periodicals, Inc.

    Full Text Available HIV-associated neurocognitive disorder (HAND is relatively frequent among HIV-infected patients and is often underdiagnosed. Assessment of HAND in daily clinical practice is challenging and different tools have been proposed. Objective : To evaluate risk factors and compare different screening tools for neurocognitive impairment in HIV-infected patients. Methods : HIV-infected patients were evaluated using the International HIV-Dementia Scale (IHDS, Mini-Mental State Examination (MMSE and a neurocognitive self-perception questionnaire recommended by the European AIDS Clinical Society. Sociodemographic, clinical and laboratory data were obtained through chart review and patient interview. Results : Among the 63 patients included, low performance on the IHDS was observed in 54.0% and IHDS score was inversely associated with age (OR 0.13; 95%CI [0.02-0.67]. Regarding cognitive self-perception, 63.5% of patients reported no impairment on the three domains covered by the questionnaire. Among those patients self-reporting no problems, 42.1% had low performance on the IHDS. None of the patients scored below the education-adjusted cut-off on the MMSE. Conclusion : IHDS scores suggestive of HAND were observed in more than half of the patients and lower scores were found among older patients. There was low agreement between the different tools, suggesting that the MMSE may be inadequate for assessing HAND. The self-assessment questionnaire had low sensitivity and might not be useful as a screening tool.

    Full Text Available Baptist Gallwitz Department of Medicine IV, Eberhard-Karls University, Tübingen, Germany Abstract: Dipeptidyl-peptidase-IV (DPP-4 inhibitors are oral antidiabetic agents that can be administered as monotherapy in patients with contraindications to metformin or metformin intolerance, and in combination with other oral compounds and/or insulin. DPP-4 inhibitors act in a glucose-dependent manner and only increase insulin secretion and inhibit glucagon secretion under hyperglycemic conditions. Renal impairment is frequent in type 2 diabetes as a result of microvascular complications and diabetes treatment, and options in these patients are limited. Linagliptin is a DPP-4 inhibitor with a hepatobiliary route of elimination. In comparative studies, it was noninferior to metformin and sulfonylureas in lowering glycated hemoglobin (HbA1c and improving glycemic parameters. It can be used throughout all stages of renal impairment without dose adjustments. This review gives an overview of linagliptin in various stages of chronic kidney disease and has a focus on efficacy and safety parameters from clinical studies in patients with impaired renal function. These data are interpreted in the context of type 2 diabetes therapy in general.

    Recently, several studies have demonstrated the role of vitamin D receptor (VDR) polymorphisms in the development of systemic lupus erythematosus (SLE). We aimed to evaluate VDR (ApaI, BsmI, and FokI) gene polymorphisms and haplotypes as a risk factors and/or activity markers for SLE, and whether they influence 25-hydroxyvitamin (25(OH) D) level. One hundred and seven SLE patients and 129 controls were enrolled in this study. Disease activity in SLE patients was assessed using Disease Activity Index. Polymorphisms of VDR gene were detected using polymerase chain reaction restriction fragment length polymorphism. Serum 25(OH) D levels were measured using ELISA. We found that ApaI AA genotype, BsmI B allele, Bb, BB genotypes, FokI F allele and FF genotype frequencies of VDR were increased in SLE group. There were significant associations of VDR ApaI AA, BsmI BB, and FokI FF genotypes with lupus nephritis and higher SLE activity scores. Moreover, serum 25(OH) D levels were increased in SLE patients carrying FokI ff genotype compared with patients carrying FF genotype. VDR haplotypes aBF and ABF were associated with SLE risk. The ABF haplotype was associated with higher SLE activity scores and lower serum 25(OH) D concentrations. We observed that the presence of leuko/lymphopenia, renal disorders, higher SLE activity scores and higher anti-dsDNA levels were accompanied by a significant decrease of serum 25(OH)D concentrations. We concluded that The VDR genes polymorphisms, haplotypes, and decreased 25(OH) D levels were associated with risk and more activity scores of SLE.

    Recognition memory--affected early in the course of Alzheimer Disease (AD)--is supposed to rely on two processes: recollection (i.e., retrieval of details from the encoding episode) and familiarity (i.e., acontextual sense of prior exposure). Recollection has repeatedly been shown to be impaired in patients with amnestic Mild Cognitive Impairment (aMCI)--known to be at high risk for AD. However, studies that evaluated familiarity in these patients have reported conflicting results. Here, we assessed familiarity in single-domain aMCI patients (n = 19) and healthy matched controls (n = 22). All participants underwent a classic yes/no recognition memory paradigm with confidence judgements, allowing an estimation of familiarity and recollection similar to the approach used in previous studies. In addition, they underwent a novel speeded recognition memory task, the Speed and Accuracy Boosting procedure, based on the idea that familiarity is fast and hence that fast answers rely on familiarity. On the classic yes/no task, aMCI patients were found to have impaired performance, reaction times, recollection and familiarity. However, performance and reaction times of aMCI patients did not differ from that of controls in the speeded task. This is noteworthy since this task was comparatively difficult for control subjects. This dissociation within familiarity suggests that a very basic component of declarative memory, probably at the interface between implicit and explicit memory, may be preserved, or possibly released, in patients with aMCI. It is suggested that early subprocesses (e.g., fluency based familiarity) could be preserved in aMCI patients, while delayed ones (e.g., conceptual fluency, post-retrieval monitoring, confidence assessment, or even access to awareness) may be impaired. These findings may provide support for recent suggestions that familiarity may result from the combination of a set of subprocesses, each with its specific temporal signature.

    Urinary bladder cancer is the 9th most common type of cancer and the 13th most common cause of death worldwide. C-erbB-4 is a class of oncogenes plays a role in cancer development. The present work was performed to assess C-erbB-4 oncogene amplification by PCR technology and its correlation with p53 and bcl-2. This study included 50 male patients (10 controls and 40 urinary bladder cancer patients). The bladder cancer patients include 20 specimens diagnosed as transitional cell carcinoma (TCC) and 20 specimens diagnosed as squamous cell carcinoma (SCC). The results revealed that 7 (35%) of both TCC and SCC showed c-erb-B2 gene amplification. 12 (60%) of TCC and 6 (30%) of SCC showed positive expression of p53. 11 (55%) of TCC and 6 (30%) of SCC showed positive Bcl-2 expression. A direct statistically significant association was detected between c-erb-B2 expression and Bcl-2 and p53 expression in TCC and SCC specimens. Seven (35%) of TCC showed c-erb-B2 gene amplification and expression of both p53 and Bcl-2. Five (25%) of the examined SCC specimens showed c-erb-B2 gene amplification and positive expression for both p53 and Bcl-2. The results indicated that a direct statistically significant association was detected in TCC group between amplification of c-erb-B2 gene by PCR and expressionof p53 and Bcl-2 by immunohistochemistry.

    This work aims to estimate the prevalence of Helicobacter pylori ureA gene and evaluate cagA gene-positive strains in both patients of laryngeal squamous cell carcinoma (LSCC) and those with benign laryngeal polyps. This study included 49 patients confirmed pathologically to have LSCC and 15 patients with benign laryngeal polyps over a period from June 2013 to March 2015. Samples of laryngeal tissue were collected during direct laryngoscope under general anesthesia to be pathologically evaluated followed by analysis for H. pylori detection. Each laryngeal tissue sample was divided into three parts; one for bacteriological examination, the second for pathological examination and the third for PCR to detect both ureA and cagA genes. Out of 49 LSCC samples, 31 (64.6 %) was positive for ureA by PCR. Out of them, 29 samples (93.5 %) were cagA positive. Only three cases (20 %) of the benign laryngeal polyp were ureA positive by PCR and one of them was cagA positive by PCR. By the bacteriological culture, only eight samples (25.8 %) gave growth. All of them were ureA positive and only seven of them were cagA positive. There was a significant association between presence of H. pylori and LSCC as compared to benign laryngeal polyp which may contribute in the pathogenesis of laryngeal carcinoma. These results should be confirmed by further studies over larger number of cases.

    Dementia is one of the most common and important aspects of Parkinson's disease and has consequences for patients and caregivers, and has health-related costs. Mild cognitive impairment is also common and frequently progresses to dementia. The underlying mechanisms of dementia associated with Parkinson's disease are only partly known and no mechanism-based treatments are available. Both dysmetabolism of α-synuclein and amyloid-protein and cholinergic deficits contribute to cognitive impairment in Parkinson's disease, and preliminary findings show that imaging and neurophysiological and peripheral biomarkers could be useful in diagnosis and prognosis. Rivastigmine is the only licensed treatment for dementia in Parkinson's disease, but emerging evidence suggests that memantine might also be useful. Whether these or other treatments can delay the progression from mild cognitive impairment to dementia in Parkinson's disease is a key research question.

    Objective: the present study was aimed at evaluating the effective radiation dose in patients submitted to PET/CT for the diagnosis of mild cognitive impairment. Materials and methods: TLD-100 detectors inserted into an Alderson Rando® anthropomorphic phantom were utilized to measure the absorbed dose coming from the CT imaging modality. The anthropomorphic phantoms (male and female adult versions) were submitted to the same technical protocols for patients’ images acquisition. The absorbed dose resulting from the radiopharmaceutical injection was estimated by means of the model proposed by the ICRP publication 106. Results: the effective dose in patients submitted to this diagnostic technique was approximately (5.34 ± 1.99) mSv. Conclusion: optimized protocols for calculation of radioactive activity injected into patients submitted to this diagnostic technique might contribute to reduce the effective radiation dose resulting from PET/CT in the diagnosis of mild cognitive impairment.

    Cervical cancer is the second most common cancer in women worldwide after breast cancer. Cervical cancer is a preventable disease. The implementation of cervical cancer screening programs has greatly decreased the morbidity and mortality, as precancerous lesions and early invasive cervical cancer could be detected and treated effectively. The detection of hTERC gene amplification was suggested as a possible diagnostic marker for use in routine cytological screening. The present study was designed to detect genomic gains of the hTERC and C-MYC genes using FISH technique and to investigate the relationship between genes amplification and the clinical data of the patients. The current study was carried out on twelve cases with cervical cancer at different grades (three cases were grade I, six cases were grade II and three cases were grade III). Interphase FISH analysis using LSI probe, Cervical Cancer probe hTERC (3q26) & C-MYC (8q24), was successfully performed on 12 patients with cancer cervix. Interphase FISH analysis revealed positive hTERC gene amplification in all cases of cancer cervix (100%). However C-MYC gene amplification was detected in four cases only (33.3%). Statistical analysis of the data revealed significant correlation between hTERC amplification and grading. Also, there was significant correlation between C-MYC amplification and grading and highly significant correlation between C-MYC amplification and hTERC amplification. On the other hand hTERC and C-MYC genes amplification showed an inverse correlation with the ages of the patients. The present study highlights the importance of using hTERC and C-MYC genes FISH probes for cases with cancer cervix or pre-malignant lesions as a sensitive technique. This method provides an easy and effective applicable approach which helps in the diagnosis and prognosis, as an increased copy number is associated with a more advanced grade that could be detected in the early stages of the disease.

    AIM: To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinoma(HCC). METHODS: The study included 154 physicians from all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 items. Each questionnaire consisted of two parts:(1) personal information regarding the physician(name, age, specialty and type of health care setting); and(2) professional experience in the care of patients at risk for HCC development(screening, knowledge about the cause and natural course of liver diseases and HCC risk). RESULTS: Sixty-eight percent of doctors with an MD degree, 48% of doctors with a master degree or a diploma and 40% of doctors with a Bachelor of Medicine, Bachelor of Surgery certificate considered the hepatitis C virus(HCV) genotype as risk factor for HCC development(P < 0.05). Ninety percent of physicians specialized in tropical medicine, internal medicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis(P < 0.05). Eighty-six percent of doctors in University Hospitals and 69% of Ministry of Health(MOH) doctors consider HCV infection as the leading cause of HCC in Egypt(P < 0.05). Seventy-two percent of doctors with an MD degree, 55% of doctors with a master degree or a diploma, 56% of doctors with an MBBCH certificate, 74% of doctors in University Hospitals and 46% of MOH hospital doctors consider abdominal ultrasonography as the most important investigation in HCC screening(P < 0.05). Sixty-five percent of physicians in tropical medicine, internal medicine or gastroenterology and 37% of physicians in other specialties recommend as HCC screening interval of 3 mo(P < 0.05). Seventy-one percent of doctors with an MD degree, 50% of doctors with a master degree or diploma and 60% of doctors with an MBBCH certificate follow the same recommendation.CONCLUSION: In Egypt, physicians

    Successful riddle solving requires recognition of the meaning of words, attention, concentration, memory, connectivity and analysis of riddle content, and sufficiently developed associative thinking. The aim of the study was to determine the ability to solve riddles in stroke patients who do or do not have speech and language disorders (SLDs), to determine the presence of SLDs in relation to the lesion localization, as well as to define the relationship between riddle-solving and functional impairment of a body side. The sample consisted of 88 patients. The data used included age, sex, educational level, time of stroke onset, presence of an SLD, lesion localization, and functional damage of the body side. The patients were presented with a task of solving 10 riddles. A significant SLD was present in 38.60% of the patients. Brain lesions were found distributed at 46 different brain sites. Patients with different lesion localization had different success in solving riddles. Patients with perisylvian cortex brain lesions, or patients with Wernicke and global aphasia, had the poorest results. The group with SLDs had an average success of solved riddles of 26.76% (p = 0.000). The group with right-sided functional impairments had average success of 37.14%, and the group with functional impairments of the left side of the body 56.88% (p = 0.002). Most patients with SLDs had a low ability of solving riddles. Most of the patients with left brain lesions and perisylvian cortex damage demonstrated lower ability in solving riddles in relation to patients with right hemisphere lesions.

    This study investigated how patients with severe aphasia communicated in daily living, which verbal and non-verbal communication skills were spared and which were impaired, and whether activity limitations in communication are related to verbal impairments. Twenty-seven patients with severe aphasia and 9 with moderate aphasia originating from a sample of 102 aphasic persons followed up in a French regional survey were assessed with a communication test and a communication activity limitation questionnaire 12-18 months after a first stroke. Patients with severe aphasia suffered severe activity limitations in communication, with performance 3-fold lower than that of patients with moderate aphasia, and 4-fold lower than scores attained by normals. Both aphasia severity and communication disability at follow-up were related to the initial severity of aphasia. Using a phone, credit card and a chequebook, reading and filling in administrative documents, and communication behaviours involved in social life were the most severely impaired. Non-verbal communication performance was not related to aphasia severity. We conclude that there is a great need for speech therapy research to develop new compensatory or alternative strategies for patients with severe aphasia.

    Memory impairment is a frequent complaint in insomniacs; however, it is not consistently demonstrated. It is unknown whether memory impairment in insomniacs involves neuroendocrine dysfunction. The participants in this study were selected from the clinical setting and included 21 patients with chronic insomnia disorder (CID), 25 patients with insomnia and comorbid depressive disorder (CDD), and 20 control participants without insomnia. We evaluated spatial working and reference memory, object working and reference memory, and object recognition memory using the Nine Box Maze Test. We also evaluated serum neuroendocrine hormone levels. Compared to the controls, the CID patients made significantly more errors in spatial working and object recognition memory (p memory types (p memory (r = .534, p = .033) and negatively correlated with the errors in object recognition memory (r = -.659, p = .006) in the CID patients. The results suggest that the CID patients had selective memory impairment, which may be mediated by increased cortisol levels. © 2016 Society for Psychophysiological Research.

    Impaired social function has been described in patients following stroke. The present study was designed to explore the degree of impairment in the ability to infer mental states in others, or cognitive and affective theory of mind, and empathy, in patients with stroke. A total of 34 patients with stroke were compared to 40 control subjects on tasks testing verbal and non-verbal theory of mind and empathy. Results indicated that patients with stroke were significantly impaired in both cognitive and affective theory of mind, even controlling for basic cognitive function and emotional processing. The patients with right stroke had poorer performance than those with left stroke on the cognitive component of non-verbal theory of mind. On the subscale of cognitive empathy, the right stroke group had poorer performance on perspective-taking than the control group. The right hemisphere may play an important role in decoding non-verbal cues to infer others' minds as well as the processing of empathy, especially the ability of perspective-taking. © 2014 The Authors.

    Network analysis has been widely used in studying Alzheimer's disease (AD). However, how the white matter network changes in cognitive impaired patients with subjective cognitive decline (SCD) (a symptom emerging during early stage of AD) and amnestic mild cognitive impairment (aMCI) (a pre-dementia stage of AD) is still unclear. Here, structural networks were constructed respectively based on FA and FN for 36 normal controls, 21 SCD patients, and 33 aMCI patients by diffusion tensor imaging and graph theory. Significantly lower efficiency was found in aMCI patients than normal controls (NC). Though not significant, the values in those with SCD were intermediate between aMCI and NC. In addition, our results showed significantly altered betweenness centrality located in right precuneus, calcarine, putamen, and left anterior cingulate in aMCI patients. Furthermore, association was found between network metrics and cognitive impairment. Our study suggests that the structural network properties might be preserved in SCD stage and disrupted in aMCI stage, which may provide novel insights into pathological mechanisms of AD.

    It is known that patients with renal disease are often administered inappropriate dosages of drugs. A lack of quantitative data in the available drug information sources and inconsistency in dosing information may augment the problem of dosing error. To determine the concordance among five drug information sources regarding the dosing recommendations provided for drugs considered problematic in patients with renal impairment and to determine the consistency among the sources regarding the definition of renal impairment and categorisation of chronic kidney disease. Five standard drug information sources were reviewed for 61 drugs recommended to be used with caution in renal impairment. Information on recommendations for dosage adjustment in renal impairment was extracted and analysed. Further, the definition and classification of renal impairment were recorded. The recommendation for each drug was coded into six different categories and the intersource reliability was calculated. Only slight agreement was observed among the sources (Fleiss Kappa: 0.3). Qualitative data were not well defined, and there was a lack of consistency in quantitative values. Some drugs marked as contraindicated in one source were not mentioned as such in others. Also, drugs considered as not requiring dosage adjustment in one source had explicit recommendations in other sources. The definition and classification of renal impairment differed among the five information sources. There should be an evidence-based approach to drug dosage adjustment in order to bring uniformity to the recommendations. Regular updating of the content of the drug information sources is also important. © 2013 The Authors; Internal Medicine Journal © 2013 Royal Australasian College of Physicians.

    The objective of this study was to investigate changes in self-awareness impairments in outpatients with acquired brain injury (ABI) and the effects these changes have on rehabilitation. Participants were 78 patients with ABI (8.3 years post-injury) who followed an intensive outpatient neuropsychological rehabilitation programme. This longitudinal study comprised pre (T1) and post (T2) measurements and a one-year follow-up (T3). Thirty-eight patients completed the study. The main outcome domains were self-awareness, depressive symptoms, psychological and physical dysfunction, and health-related quality of life (HRQoL). Patients were divided into three awareness groups: underestimation, accurate estimation, and overestimation of competencies. Most patients who underestimated their competencies at the start of treatment accurately estimated their competencies directly after treatment (9 out of 11 patients). These patients also exhibited the largest treatment effects regarding depressive symptoms, psychological and physical dysfunction, and HRQoL. Most patients with impaired self-awareness (i.e., overestimation of competencies) at the start of treatment continued to overestimate their competencies after treatment (10 out of 14 patients). These patients exhibited a significant decrease in depressive symptoms but no other treatment effects. The results indicate that changes in outcome are related to changes in awareness, which underline the importance of taking into account different awareness groups with respect to treatment effects.

    Budd-Chiari syndrome (BCS) is defined as obstruction of hepatic venous outflow anywhere from the small hepatic veins to the suprahepatic inferior vena cava. The pathogenesis of BCS is still not fully understood. This study aimed to evaluate the association of factor V Leiden (FVL), Janus kinase 2 (JAK2), prothrombin, and methylene tetrahydrofolate reductase (MTHFR) mutations with primary BCS. The study was carried out on 35 patients with primary BCS and 15 age and gender matched healthy individuals as a control group. Genotyping of FVL, prothrombin, and MTHFR mutations was determined by GENEQUALITY AB-THROMBO TYPE kit based on the reverse hybridization principle. JAK2 mutation was determined by polymerase chain reaction-restriction fragment length polymorphism. There was a statistically significant difference between patients and controls regarding FVL, MTHFR C677T, and MTHFR A1298C mutations with odds ratio of 1.83, 2.0, and 1.79, respectively. Hetero MTHFR C677T, hetero FVL, and hetero MTHFR A1298C were the most common etiological factors being responsible for 57.1, 42.9, and 42.9% of primary BCS cases, respectively. It could be concluded that BCS is a multifactorial disease; in the current study, MTHFR C677T mutation was the most common cause of disease. Identification of one cause of BCS should not eliminate investigations for detection of other etiological factors. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    The evidence for increased risk of dementia in relatives of patients with Parkinson disease (PD) remains conflicting. To study the risk of cognitive impairment or dementia in first-degree relatives of patients with PD. We conducted a historical cohort study of 1019 first-degree relatives of 162 patients with PD and of 858 relatives of 147 matched controls representative of the population of Olmsted County, Minnesota. In addition, we studied 2716 first-degree relatives of 411 patients with PD referred to Mayo Clinic. We administered via telephone a cognitive test directly to relatives or a dementia questionnaire to proxies. For relatives reported by proxies to have dementia, we obtained copies of their medical records to confirm the diagnosis. We also obtained dementia information from a medical records-linkage system. In the overall population-based sample, the risk of cognitive impairment or dementia was increased in relatives of patients with PD compared with relatives of controls (hazard ratio, 1.37; 95% confidence interval, 1.03-1.81; P = .03) and was particularly increased in relatives of patients with onset of PD at age 66 years or younger (youngest tertile; hazard ratio, 1.73; 95% confidence interval, 1.21-2.46; P = .003). The findings were consistent in several sensitivity analyses. In the referral-based sample, the risk of cognitive impairment or dementia in relatives increased with younger age at onset of PD but did not vary by other clinical characteristics. Cognitive impairment or dementia may share familial susceptibility factors with PD (genetic or nongenetic).

    To perform a comprehensive study of intestinal digestion, absorption, and microbiocenosis in various stages of cholelithiasis (CL). A total of 76 patients with of CL, including 44 patients with its Stage I and 32 patients with Stage II, were examined. Mono-, di - and polysaccharide load tests and a scatological study were performed to evaluate the processes of digestion and absorption in the intestine. The hydrogen breath test using lactulose was carried out to study small intestinal bacterial overgrowth (SIBO). The state of colon microbiocenosis was determined by plating feces onto various selective nutrient media. All digestive process stages in the small intestine were noted to be impaired in CL. In Stage I CL, cavitary digestion was mainly impaired; in Stage II, all digestive and absorptive processes were abnormal. Scatological examination in patients with Stage I CL revealed steatorrhea in 79.5%, creatorrhea in 75%, and amylorrhea in 36.4%. In Stage II CL, digestive and absorptive disorders progressed. SIBO was detected in 68.5% whereas in 70% of cases, it was located in the distal small intestine in the presence of insufficiency of the ileocecal sphincter apparatus. A regularity was found between the severity of SIBO and impaired small intestinal cavitary digestion. SIBO was more common in the pre-gallstone stage of CL than in its gallstone stage. Dysbiosis of the colon was detected in 100% of the examined patients with CL; moreover, as the latter progressed, dysbiosis worsened. There is new information about impaired intestinal digestion and microbiocenosis in patients with CL.

    Theory of mind (ToM) impairment has been consistently demonstrated in patients with schizophrenia, but whether ToM impairments exist in unaffected siblings of patients with schizophrenia remains unclear. Few studies have examined the affective and cognitive components of ToM in schizophrenia. This study aimed to examine whether ToM impairments exist in patients with first-episode schizophrenia and their unaffected siblings, and whether there is any dissociation between the affective and cognitive components of ToM. We adopted a family-based case-control design. Participants were 41 patients with first-episode schizophrenia, 43 unaffected siblings, and 42 healthy controls. The Yoni Task which measures the participants' ability to understand first- and second-order affective versus cognitive ToM and the Faux Pas Task which taps into integration of the affective and cognitive components of ToM were administered. Multivariate and univariate ANCOVAs were used to examine the group differences in ToM, while controlling for other neurocognitive functions. Compared with controls, patients with schizophrenia and their unaffected siblings performed poorer on the Faux Pas Task (pschizophrenia performed worse than controls on second-order affective condition of the Yoni Task (p=0.004), but their unaffected siblings did not (p=0.063). We did not find any significant Group-by-Condition interaction in the Yoni Task (p=0.358). Patients with first-episode schizophrenia and their unaffected siblings exhibit ToM impairments, but no dissociation between affective and cognitive component of ToM was found. Our findings support the notion that ToM deficit may be a trait marker of schizophrenia. Copyright © 2014 Elsevier B.V. All rights reserved.

Thus, understanding emotional face recognition deficit in patients with amnestic MCI could be useful in determining progression of amnestic MCI. The purpose of this study was to investigate the features of emotional face processing in amnestic MCI by using event-related potentials (ERPs. Patients with amnestic MCI and healthy controls performed a face recognition task, giving old/new responses to previously studied and novel faces with different emotional messages as the stimulus material. Using the learning-recognition paradigm, the experiments were divided into two steps, ie, a learning phase and a test phase. ERPs were analyzed on electroencephalographic recordings. The behavior data indicated high emotion classification accuracy for patients with amnestic MCI and for healthy controls. The mean percentage of correct classifications was 81.19% for patients with amnestic MCI and 96.46% for controls. Our ERP data suggest that patients with amnestic MCI were still be able to undertake personalizing processing for negative faces, but not for neutral or positive faces, in the early frontal processing stage. In the early time window, no differences in frontal old/new effect were found between patients with amnestic MCI and normal controls. However, in the late time window, the three types of stimuli did not elicit any old/new parietal effects in patients with amnestic MCI, suggesting their recollection was impaired. This impairment may be closely associated with amnestic MCI disease. We conclude from our data that face recognition processing and emotional memory is

    Coronary disease has been associated with cognitive disorders. We studied the presence of dysexecutive mild cognitive impairment in patients scheduled for coronary surgery. The executive function of 35 patients was evaluated (Trail Making Test). They were classified into 2 groups: normal performance or cognitive impairment, and we assessed the relationship with others variables (Mann-Whitney, chi-square and multiple regression analysis). The dysexecutive cognitive impairment group (n=7; 20%) showed greater degree of angina (odds ratio [OR] 1.4, 95% confidence interval [95% CI] 1.1-2.6; P=.04), 3-vessels coronary artery disease (OR 1.3, 95% CI 1.08-3.6; P=.04) and body mass index (OR 1.56, 95% CI 1.16-3.65; P=.03) and lower diastolic blood pressure (OR 1.56, 95% CI 1.2-2.98; P=.02), hemoglobin (OR 2.03, 95% CI 1.18-4.05; P=.02) and hematocrit (OR 2.45, 95% CI 1.67-3.99; P<.001); these variables proved to be significant in the test performance considered as a dependent variable (R(2)=0.62). We found a significant prevalence of dysexecutive mild cognitive impairment, which was associated with cardiovascular risk factors. We recommend assessment and monitoring of cognitive performance for probable neurological complications after cardiac surgery. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Full Text Available BACKGROUND: Memory disturbances, in particular episodic verbal memory dysfunction, are the most frequent cognitive impairment observed in multiple sclerosis (MS patients. The use of self-reported outcomes for evaluating treatment and managing care of these subjects has been questioned. The aim of this study was to provide new evidence about the suitability of self-reported outcomes for use in this impaired population by exploring the internal structure, reliability and external validity of a specific quality of life (QoL instrument, the Multiple Sclerosis International Quality of Life questionnaire (MusiQoL. METHODS: DESIGN: cross-sectional study. INCLUSION CRITERIA: MS patients of any disease subtype. DATA COLLECTION: sociodemographic (age, gender, marital status, education level, and occupational activity and clinical data (MS subtype, Expanded Disability Status Scale, disease duration; QoL (MusiQoL and SF36; and memory performance (Grober and Buschke test. In accordance with the French norms of the memory test, non-impaired and impaired populations were defined for short- and long-delay free composites and for short- and long-delay total composites. For the 8 populations, psychometric properties were compared to those reported from the reference population assessed in the validation study. PRINCIPAL FINDINGS: One hundred and twenty-four consecutive patients were enrolled. The analysis performed in the impaired populations showed that the questionnaire structure adequately matched the initial structure of the MusiQoL. The unidimensionality of the dimensions was preserved, and the internal/external validity indices were close to those of the reference population. CONCLUSIONS/SIGNIFICANCE: Our study suggests that memory dysfunction did not compromise the reliability or validity of the self-reported QoL questionnaires.

    Full Text Available Serum neutral amino acid levels in cirrhotic patients with abnormal oral glucose tolerance test patterns were not different from those of subjects without impaired carbohydrate metabolism. However, the characteristic features of serum aminograms in the patients, that is, increased levels of tyrosine, decreased levels of valine and leucine and the diminished ratio of branched chain amino acids to phenylalanine and tyrosine levels, were less pronounced in those treated with insulin. This finding is clinically important for evaluating the serum aminogram of cirrhotic patients under insulin therapy.

    Declarative memory for rapidly learned, novel associations is thought to depend on structures in the medial temporal lobe (MTL), whereas associations learned more gradually can sometimes be supported by nondeclarative memory and by structures outside the MTL. A recent study suggested that even rapidly learned associations can be supported by structures outside the MTL when an incidental encoding procedure termed "fast mapping" (FM) is used. We tested six memory-impaired patients with bilateral damage to hippocampus and one patient with large bilateral lesions of the MTL. Participants saw photographs and names of animals, plants, and foods that were previously unfamiliar (e.g., mangosteen). Instead of asking participants to study name-object pairings for a later memory test (as with traditional memory instructions), participants answered questions that allowed them to infer which object corresponded to a particular name. In a second condition, participants learned name-object associations of unfamiliar items by using standard, explicit encoding instructions (e.g., remember the mangosteen). In FM and explicit encoding conditions, patients were impaired (and performed no better than a group that was given the same tests but had not previously studied the material). The same results were obtained in a second experiment that used the same procedures with modifications to allow for more robust learning and more reliable measures of performance. Thus, our results with the FM procedure and memory-impaired patients yielded the same deficits in learning and memory that have been obtained by using other more traditional paradigms.

    Midazolam is a widely used sedative agent during colonoscopy, with cognitive toxicity. However, the potential cognitive hazard of midazolam-based light sedation has not been sufficiently examined. We aimed to examine the cognitive safety and vulnerability profile under midazolam light sedation, with a particular focus on individual variations. We conducted a prospective case-controlled study in an academic hospital. In total, 30 patients undergoing sedative colonoscopy as part of a health check-up were recruited. Neuropsychological testing on the full cognitive spectrum was evaluated at 15 minutes and 120 minutes after low-dose midazolam administration. The modified reliable change index (RCI) was used for intrapersonal comparisons and controlling for practice effects. Midazolam affected psychomotor speed (48%), memory (40%), learning (32%), working memory (17%), and sustained attention (11%), while sparing orientation and the fluency aspect of executive function at the acute stage. Residual memory (10%) and learning (10%) impairments at 2 hours after administration were evidenced in some patients. The three object recall and digit symbol coding tests can serve as useful screening tools. Midazolam-based light sedation induced selective cognitive impairments and prolonged cognitive impairments occurred in patients with advanced age. A longer observation time and further screening were recommended for patients due to their at risk state. Copyright © 2013. Published by Elsevier B.V.

    Full Text Available Oxidative stress affects clinical outcome in critically ill patients. Although high-density lipoprotein (HDL particles generally possess anti-oxidant capacities, deleterious properties of HDL have been described in acutely ill patients. The impact of anti-oxidant HDL capacities on clinical outcome in critically ill patients is unknown. We therefore analyzed the predictive value of anti-oxidant HDL function on mortality in an unselected cohort of critically ill patients.We prospectively enrolled 270 consecutive patients admitted to a university-affiliated intensive care unit (ICU and determined anti-oxidant HDL function using the HDL oxidant index (HOI. Based on their HOI, the study population was stratified into patients with impaired anti-oxidant HDL function and the residual study population.During a median follow-up time of 9.8 years (IQR: 9.2 to 10.0, 69% of patients died. Cox regression analysis revealed a significant and independent association between impaired anti-oxidant HDL function and short-term mortality with an adjusted HR of 1.65 (95% CI 1.22-2.24; p = 0.001 as well as 10-year mortality with an adj. HR of 1.19 (95% CI 1.02-1.40; p = 0.032 when compared to the residual study population. Anti-oxidant HDL function correlated with the amount of oxidative stress as determined by Cu/Zn superoxide dismutase (r = 0.38; p<0.001.Impaired anti-oxidant HDL function represents a strong and independent predictor of 30-day mortality as well as long-term mortality in critically ill patients.

    Full Text Available Objective: to identify the indicators of bioelectrical activity of the cerebral cortex, which are associated with cognitive impairments in patients with coronary artery disease (CAD.Patients and methods. The study included 122 male patients aged 45 to 69 years with CAD. Sixty of them were found to have mild cognitive impairments (MCI, their average Mini-Mental State Examination (MMSE score was 26.2±0.90; the other 62 patients had no cognitive impairment; their MMSE score was 28.5±0.86. All the patients underwent clinical and instrumental examinations and computer-based multichannel electroencephalography (EEG. Eyes-closed and eyes-open resting EEG monopolarly recorded in 62 standard leads of the 10-20 system. A binary logistic regression analysis was used to identify EEG predictors of MCI in patients with CAD.Results. The high power values of theta1-rhythm biopotentials with closed eyes in the frontal and occipital areas of the left hemisphere and those of alpha2-rhythm ones with open eyes in the frontal areas of the right hemisphere, and the high theta/alpha EEG power ratio are associated with an increased risk of MCI in CAD patients. The most important clinical and anamnestic factors associated with a decreased risk of MCI were higher education level, the lack of type 2 diabetes, and milder coronary bed lesions according to the SYNTAX scale. There was an association of the power values of the biopotentials and theta/alpha EEG power ratio and the development of MCI in CAD patients.

    The use of the pigment Egyptian blue is investigated on a corpus of fifteen mummy portraits and Roman-period paintings from Tebtunis, Egypt, housed in the Phoebe A. Hearst Museum of Anthropology at the University of California, Berkeley. Egyptian blue has a strong luminescence response in the near infrared that can be exploited to created wide-field images noninvasively showing the distribution of the pigment on a work of art. A growing body of publications in the last decade highlights the increasing use of this tool and its sensitive detection limits. However, the technique is not wavelength specific. Both excitation and emission occur in a broad range. Although Egyptian blue has a strong emission in the NIR, a myriad of other compounds may emit light in this spectral region when excited in the visible. The limited number of studies including complementary analysis to verify the presence of Egyptian blue does not allow its identification on the basis of NIR luminescence alone. Through the use of in situ X-ray fluorescence and X-ray diffraction, and scanning electron microscopy/energy-dispersive spectroscopy of cross sections, this paper confirms the identification of Egyptian blue by NIR luminescence in unexpected areas, i.e., those not blue in appearance.

    Parkinsons disease (PD) is a neurodegenerative disorder that represents cognitive impairment as well as motor symptoms. Even in the early stages of PD, cognitive alterations can be demonstrated by careful neuropsychological test. The purposes of this study are to investigate the pattern of cognitive impairment and the regional cerebral blood flow (rCBF) using Tc-99m HMPAO SPECT in patients with PD. One hundred and twenty two patients with PD and 35 control subjects participated in this study. Patients with PD who had dementia clinically or K-MMSE score below 25 points or with severe motor dysfunction to interfere with the tests were also excluded. They were all matched for age (61{+-}10 vs 61{+-}8), education periods (8.8{+-}4.9 vs 8.8{+-}4.5), and K-MMSE score (27{+-}1.6 vs 27{+-}1.5). All subjects were evaluated using the Seoul Neuropsychological Screening Battery (SNSB) and Tc-99m HMPAO SPECT with SPM software to measure rCBF. Patients with PD performed worse in digit span backward, Rey Complex Figure Test, visual memory, semantic fluency, stroop test, and alternating hand movement test(p<0.05) compared with control group. On SNSB test, 100 patients (82.0%) showed some abnormalities. Eighty-six patients (70.5%) showed frontal dysfunction, 47 (38.5%) memory impairment, 33 (27.0%) language dysfunction, 25 (20.5%) attention deficit and 22 (18.3%) visuospatial dysfunction in the order of frequency. Eight patients with PD showed single memory domain MCI and 28 single non-memory domain MCI (20 frontal dysfunction). Multiple domain MCI was found in 64 patients with PD. SPM analysis of the SPECT image revealed multiple perfusion deficit in the both frontal, temporal, both limbic lobes, Lt. parietal and Lt. Putamen. It is concluded that abnormalities of cognitive function be detected very commonly in patients with PD. MCI in PD patients is most frequently involved in the item of frontal lobe function. SPECT image might be helpful to explain cognitive impairment in some

    BACKGROUND: Gastrointestinal symptoms are a common feature in infants with congenital heart disease. AIM: This study was designed to evaluate age-dependent serum levels of antigliadin antibodies among malnourished Egyptian infants with congenital heart disease (CHD) and gastrointestinal symptoms. SUBJECTS AND METHODS: This case-control study conducted on 60 infants with established congenital heart disease. They were subdivided into cyanotic and acyanotic groups, and each group includes 30 patients compared with thirty apparently healthy infants of matched age, sex, and social class. Serum antigliadin antibodies levels were measured using ELISA. RESULTS: The mean age of introduction of cereals in the diet and appearance of gastrointestinal symptoms were six months. On comparison with controls, patients showed highly significant higher serum levels of antigliadin antibodies (P Gluten containing foods should never be introduced before the end of the six months.

Neuropsychological impairment is highly related to functional outcomes in patients with psychiatric disorders, and several studies have suggested an association between neuropsychological impairment and violent behaviors. However, there have been no studies of neuropsychological impairment in forensic patients covered by the Japanese legislation. This study is designed to examine the neuropsychological characteristics of forensic patients in comparison to healthy controls and to assess the relationship between neuropsychological impairment and violence risk.Seventy-one forensic patients with psychiatric disorders and 54 healthy controls (matched by age, gender, and education were enrolled. The CogState Battery (CSB consisting of eight cognitive domains, the Iowa Gambling Task (IGT to test emotion-based decision making, and psychological measures of violence risk including psychopathy were used.Forensic patients exhibited poorer performances on all CSB subtests and the IGT than controls. For each group, partial correlational analyses indicated that poor IGT performance was related to psychopathy, especially antisocial behavior. In forensic patients, the CSB composite score was associated with risk factors for future violent behavior, including stress and noncompliance with remediation attempts.Forensic patients with psychiatric disorders exhibit a wide range of neuropsychological impairments, and these findings suggest that neuropsychological impairment may increase the risk of violent behavior. Therefore, the treatment of neuropsychological impairment in forensic patients with psychiatric disorders is necessary to improve functional outcomes as well as to prevent violence.

    Cognitively impaired patients often pull at their dialysis catheters when the catheters are tunneled over the anterior chest. To potentially circumvent this, a technique was developed that tunnels the catheter posteriorly, over the patient's shoulder. A total of 32 posteriorly tunneled catheters were placed in 12 patients. The mean catheter use interval was 164 days, with a total of 5,248 catheter use days. Indications for nonelective catheter removals were catheter dysfunction (n = 7; 23.3%), removal by the patient (n = 7; 23.3%), infection (n = 5; 16.7%), and inadvertent dislodgment (n = 1; 3.3%). Only six of the 12 patients were able to dislodge their catheters. The procedure described here reduced catheter manipulation and extended catheter viability in these patients. Copyright © 2014 SIR.

    Abstract This study aimed to investigate prospective memory impairment in patients with breast cancer with different expression of hormone receptors, including the estrogen receptor (ER) and the progesterone receptor (PR). A total of 120 patients with breast cancer who underwent chemotherapy following surgery were divided into 2 groups. The A group included 60 patients with ER−/PR− status, and the B group included 60 patients with ER+/PR+ status. After 6 cycles of postoperative adjuvant chemotherapy, all patients were administered neuropsychological and prospective memory tests, such as the Mini-Mental State Examination (MMSE), verbal fluency test (VFT), and digit span test (DST), as well as examination of event-based prospective memory (EBPM) and time-based prospective memory (TBPM). As the neuropsychological background test results showed, there were no significant differences in MMSE, DST, and TBPM scores (∗:P > 0.05) between patients with breast cancer in the ER−/PR− and ER+/PR+ groups, while the VFT and EBPM scores were significantly greater in patients with breast cancer with ER+/PR+ status than in those with ER−/PR− status (∗∗: P memory impairment.

    We examined the qualitative polymorphonuclear neutrophil (PMN)-associated immune impairment in patients with chronic lymphocytic leukemia (CLL) by characterizing phagocytic killing of key non-opsonized bacterial (Staphylococcus aureus and Pseudomonas aeruginosa) and fungal (Candida albicans and Aspergillus fumigatus) pathogens. Neutrophils were collected from 47 non-neutropenic patients with CLL (PMN count > 1000/mm(3)) and age-matched and young healthy controls (five each). A subset of patients (13%) had prior or subsequent infections. We found that the patients with CLL had diminished PMN microbicidal response against bacteria but not against fungi compared with the controls. Compared to patients with effective PMN responses, we did not identify differences of basal PMN pathogen-associated molecular pattern receptor gene expression, soluble pathogen-associated molecular pattern gene expression or inflammatory cytokine signatures in patients with impaired PMN responses when PMNs were analyzed in multiplex real-time polymerase chain reaction assays. However, differences in PMN microbicidal response against A. fumigatus in patients with CLL were associated with the degree of hypogammaglobulinemia.

    Full Text Available The results of prophylaxis of acute impairment of a cerebral circulation with the help of carotid endarterectomy (CEAE are considered. There are examined 324 patients with cerebrovascular pathology 132 of them have transferred CEAEand 156 received only conservative therapy. The results of Wyears observation of operated and non operated patients show, that in patients, who were operated, in mostcases the marked signs of impairment of cerebral circulation in ipsilateral hemisphere were not developed. The results of observation over group of patients who were not operated coincide with the average data according to which the patients who have suffered an ischemic insult, have the riskof development of the subsequent insult at a level of 5-9% in a year, and approximately 25-45% of them have a repeated insult during 5 years period after the first insult. The best clinical effect had CEAE, performed in patients with transitional ischemic attacks. CEAE is the main preventive measure in treatment of patients with an atherosclerotic stenosis of carotids. The analysis of the results of the research testifies to the stable and long-term effect of operation.

    Full Text Available Introduction: The aim of our study was to investigate the potential relationship between liver fibrosis (LF and cognitive performance in HIV+ patients. Materials and Methods: We performed a cross-sectional cohort study by consecutively enrolling HIV+ patients during routine outpatient visits at two clinical centres in Italy. Subjects with decompensated liver disease were excluded. All subjects underwent a comprehensive neuropsychological battery exploring memory, attention, psychomotor speed and language; cognitive impairment was defined as at least two abnormal [1.5 SD below the mean for appropriate norms] cognitive domains. LF was explored by calculating FIB4 index; in a subgroup of patients, LF was also assessed by transient elastography. Factors associated with cognitive impairment were investigated by logistic regression models. Results: A total of 413 patients [77% males, median age 46 (IQR 39–52, 17% with past AIDS-defining events, 19% past IDU, 3% with diabetes, 94% on cART, 90% with HIV RNA 3.25 and 14/129 (3% had liver stiffness >14KPa. Forty-seven patients (11% were diagnosed with cognitive impairment.

    Compared with a group of age matched controls, patients with Parkinson's disease scored significantly lower in testing for ideomotor apraxia. Imitation of movement sequences was affected more severely than performance of single movements. The degree of impairment was not related to severity of motor disability, but correlated strongly with the results of tests that measured visuospatial and visuoperceptive abilities. It is suggested that defective encoding and central processing of visuospati...

    The extent to which MS patients with cognitive dysfunction can accurately self-report outcomes has been a crucial issue. The aim of this study was to quantify and compare the relevance of the quality of life (QoL) assessment between two populations with a high occurrence of cognitive dysfunction, specifically in individuals with multiple sclerosis (MS) and in individuals suffering from schizophrenia (SCZ). A cross-sectional study was performed using the following inclusion criteria: MS and SCZ patients were diagnosed according to the McDonald criteria and DSM-IV criteria, respectively. Data on sociodemographic (age, gender, education level) and clinical (disease severity, disease duration) factors, QoL (disease-specific questionnaires, MusiQoL and SQoL) and cognitive performance (executive, memory, and attention functions) were collected. Non-impaired and impaired populations were defined according to the French norms. Psychometric properties were compared to those reported in reference populations, which were assessed in the respective validation studies. Suitability indices were provided used to quantitatively compare how the structures in the different populations matched with the initial structure of the questionnaires (reference populations). One hundred and twenty-four MS patients and 113 SCZ patients were enrolled. Factor analysis was performed on the impaired populations and revealed that the questionnaire structure adequately matched the initial structure of the disease-specific QoL questionnaires. All of the suitability indices of construct and external validity in the non-impaired populations ranged from 70 to 100%. Our study suggested that cognitive dysfunction did not compromise the reliability or validity of the self-reported QoL questionnaires among subjects with cognitive dysfunction, such as MS and SCZ. Thus, this report may clarify the relevance of using self-reported QoL assessments in clinical practice.

The way potential users perceive telecare and smart home systems plays a key role in their acceptance of this new technology. We evaluate the acceptance of home telecare technologies among patients suffering from cognitive impairment and their caregivers. Prototypes of telecare devices were developed to demonstrate their features and capabilities and to train patients, families, and health care professionals in their use. We conducted semistructured interviews to elicit the perceptions of 30 patients with mild cognitive impairment, 32 patients with Alzheimer’s disease, and 30 caregivers, regarding the risks and advantages of home telecare and smart houses. Survey results reflected participants' largely positive reactions to these technologies. Regarding home telecare, the cognitive stimulation program earned the highest proportion of positive responses, followed by the devices' care of emergencies. The participants generally agreed that home telecare and smart houses could significantly improve their quality of life. However, some technical and ethical concerns, such as the way of provision, installation, and monitoring of the systems, were reported to be in need of addressing before implementation of this system.

    Objective To compare two definitions of neurocognitive impairment (NCI) in a large clinical trial of effectively-treated HIV-infected adults at baseline. Methods Hopkins Verbal Learning test-Revised (HVLT-R), Colour Trail (CTT) and Grooved Pegboard (GPT) tests were applied exploring five cognitive domains. Raw scores were transformed into Z-scores and NCI defined as summary NPZ-5 score one standard deviation below the mean of the normative dataset (i.e. <−1SD) or Z-scores <−1SD in at least two individual domains (categorical scale). Principal component analysis (PCA) was performed to explore the contribution of individual tests to the total variance. Results Mean NPZ-5 score was −0.72 (SD 0.98) and 178/548 (32%) participants had NPZ-5 scores <−1SD. When impairment was defined as <−1SD in at least two individual tests, 283 (52%) patients were impaired. Strong correlations between the two components of the HVLT-R test (learning/recall) (r = 0.73), and the CTT and (attention/executive functioning) (r = 0.66) were observed. PCA showed a clustering with three components accounting for 88% of the total variance. When patients who scored <−1SD only in two correlated tests were considered as not impaired, prevalence of NCI was 43%. When correlated test scores were averaged, 36% of participants had NPZ-3 scores <−1SD and 32% underperformed in at least two individual tests. Conclusion Controlling for differential contribution of individual test-scores on the overall performance and the level of correlation between components of the test battery used appear to be important when testing cognitive function. These two factors are likely to affect both summary scores and categorical scales in defining cognitive impairment. Trial registration EUDRACT: 2007-006448-23 and ISRCTN04857074. PMID:25078406

Methods. A total of 246 eyes of 123 people (41 ATD, 38 MCI, and 44 healthy C subjects were included in this study. Complete ophthalmological and neurological examination was performed in all subjects. Choroidal thicknesses (CT were measured at seven locations: the fovea, 500-1500-3000 μm temporal and 500-1500-3000 μm nasal to the fovea by enhanced depth imaging optical coherence tomography (EDI-OCT. Detailed neurological examination including mini mental state examination (MMSE test which evaluates the cognitive function was applied to all participants. Results. The ages and genders of all participants were similar in all groups. Compared with healthy C subjects, the CT measurements at all regions were significantly thinner both in patients with ATD and in patients with MCI than in healthy C subjects (p<0.05. The MMSE scores were significantly different among ATD patients, MCI patients, and healthy C subjects.

    Full Text Available Introduction The number of patents with dementia increases among hip fracture patients. Cognitive dysfunction is defined as a premorbid state which is potentionally negatively related to short-term functional outcome. Objective To assess the relationship between cognitive status on admission and functional gain during an early rehabilitation period in elderly hip fracture patients. Methods Forty-five elderly patients with surgically treated hip fracture were examined. Cognitive status was assessed by the Mini Mental State Examination (MMSE at admission; functional status was assessed by the motor subscale of Functional Independence Measure (FIM at admission and before discharge, while absolute functional gain was determined by the motor FIM gain (FIM discharge - FIM admission. Absolute functional gain was analyzed in respect to cognitive status. Results Both cognitively impaired and cognitively intact hip fracture patients exhibited overall FIM motor improvements, as well as functional gains in specific FIM motor areas (p<0.01. Absolute functional gain, however, was higher in 1 cognitively intact compared to cognitively impaired patients (p<0.01, and 2 cognitively moderately impaired patients compared to severely cognitively impaired patients (p<0.01. No difference in functional gain was detected between the patients with moderately cognitively impaired compared to the cognitive intact patients (p>0.05. Conclusion The systematic use of MMSE identifies cognitively impaired hip fracture patients, and effectively predicts their short-term functional outcome. A higher admission cognitive status is related to a more favorable short term rehabilitation outcome. In spite of cognitive impairment, elderly patients with hip fracture can benefit from participation in rehabilitation programmes. The systematic identification of cognitively impaired hip fracture patients at admission facilitates optimal treatment and rehabilitation, and thus enables the best

    Sepsis and septic shock are major contributors to morbidity and mortality in intensive care patients. Early identification and adequate therapy are of utmost importance to reduce the still high mortality in patients with severe sepsis. Many of the pathophysiologic changes are nonspecific. Thus, a combination of symptoms and laboratory results are necessary to confirm the diagnosis. Impairment of the Horovitz index is identified as being a primal prognostic criterion for early diagnosis in serious progression of sepsis, after exclusion of a few differential diagnoses. Based on this fact, the prevalence of this symptom compared to other sepsis parameters is of specific interest. In a retrospective study 33 cases of serious sepsis were analysed during the patient's course of intensive care treatment focusing on oxygenation. The deterioration of oxygenation, meaning a drop in the Horovitz index below 200 mm Hg (25.7 kPa) or a decrease in paO2 by 67.5 mm Hg (9 kPa) in spontaneously breathing patients with sepsis was the mean inclusion criteria. We compared the sequence of occurrence of known sepsis markers (e. g. PCT, WBC, CRP) with the deterioration in oxygenation to answer the question whether impairment of oxygenation could be an early symptom of severe sepsis. The Mann Whitney U‑test and a discriminant analysis were performed to verify differences of the variables investigated between surviving and deceased patients. Furthermore a regression analysis was performed to confirm the results of the discriminant analysis. The mean drop in the Horovitz index was 90 ± 24 mm Hg (12 ± 3.2 kPa) within 4.5 h respectively. This was highly significant (p sepsis. In more than ¾ of all cases this symptom occurred in an earlier stage than other organ dysfunctions. In 79 % of cases, patients showed an impairment of oxygenation before PCT increased on values of >2 ng/ml. In 76 % of cases impairment of oxygenation occurred earlier than all other

    Christian Gunge Riberholt

    Full Text Available Early mobilization is of importance for improving long-term outcome for patients after severe acquired brain injury. A limiting factor for early mobilization by head-up tilt is orthostatic intolerance. The purpose of the present study was to examine cerebral autoregulation in patients with severe acquired brain injury and a low level of consciousness. Fourteen patients with severe acquired brain injury and orthostatic intolerance and fifteen healthy volunteers were enrolled. Blood pressure was evaluated by pulse contour analysis, heart rate and RR-intervals were determined by electrocardiography, middle cerebral artery velocity was evaluated by transcranial Doppler, and near-infrared spectroscopy determined frontal lobe oxygenation in the supine position and during head-up tilt. Cerebral autoregulation was evaluated as the mean flow index calculated as the ratio between middle cerebral artery mean velocity and estimated cerebral perfusion pressure. Patients with acquired brain injury presented an increase in mean flow index during head-up tilt indicating impaired autoregulation (P < 0.001. Spectral analysis of heart rate variability in the frequency domain revealed lower magnitudes of ~0.1 Hz spectral power in patients compared to healthy controls suggesting baroreflex dysfunction. In conclusion, patients with severe acquired brain injury and orthostatic intolerance during head-up tilt have impaired cerebral autoregulation more than one month after brain injury.

    Full Text Available Background and Purpose. Regulatory T cells (Tregs have been suggested to modulate stroke-induced immune responses. However, analyses of Tregs in patients and in experimental stroke have yielded contradictory findings. We performed the current study to assess the regulation and function of Tregs in peripheral blood of stroke patients. Age dependent expression of CD39 on Tregs was quantified in mice and men. Methods. Total FoxP3+ Tregs and CD39+FoxP3+ Tregs were quantified by flow cytometry in controls and stroke patients on admission and on days 1, 3, 5, and 7 thereafter. Treg function was assessed by quantifying the inhibition of activation-induced expression of CD69 and CD154 on T effector cells (Teffs. Results. Total Tregs accounted for 5.0% of CD4+ T cells in controls and <2.8% in stroke patients on admission. They remained below control values until day 7. CD39+ Tregs were most strongly reduced in stroke patients. On day 3 the Treg-mediated inhibition of CD154 upregulation on CD4+ Teff was impaired in stroke patients. CD39 expression on Treg increased with age in peripheral blood of mice and men. Conclusion. We demonstrate a loss of active FoxP3+CD39+ Tregs from stroke patient’s peripheral blood. The suppressive Treg function of remaining Tregs is impaired after stroke.

    The Egyptian swift Rock Pigeon is a breed of fancy pigeon developed over many years of selective breeding. In this work, we report the complete mitochondrial genome sequence of Egyptian swift Rock Pigeon. The total length of the mitogenome was 17,239 bp and its overall base composition was estimated to be 30.2% for A, 24.0% for T, 31.9% for C and 13.9% for G, indicating an A-T (54.2%)-rich feature in the mitogenome. It contained the typical structure of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes and a non-coding control region (D-loop region). The complete mitochondrial genome sequence of Egyptian swift Rock Pigeon would serve as an important data set of the germplasm resources for further study.

    Full Text Available Objectives: Investigate gender related differences in somatic symptoms, severity of depression, quality of life (QOL, and functional impairment, and correlate somatic symptoms with QOL and functional impairment. Methods: This cross-sectional study was conducted with 100 consecutive outpatients seeking treatment for depressive disorder at district hospital psychiatric outpatient clinic, Kolar, Karnataka, India. This study utilised the Beck Depression Inventory II, Physical Distress Scale, Work and Social Adjustment Scale, and World Health Organization QOL BREF instrument. Results: Mean constipation scores and back pain scores were higher in women compared to men. There were no statistically significant differences between male and female patients with regard to depression scores, total somatic symptom scores, QOL, and functional impairment scores. Somatic symptoms scores are positively correlated with depression scores and functional impairment scores, and negatively correlated with QOL scores. Conclusion: Women had higher constipation and back pain scores compared to men. If the symptoms of same disease differ between men and women, this has important implications for the history collection, diagnosis, and treatment process.

    2014-04-01

    Full Text Available INTRODUCTION: Heart failure (HF is a complex syndrome in which effort limitation is associated with deterioration of peripheral musculature. Improving survival rates among these patients have led to the appearance of cases in which other pathologies are associated with HF, such as peripheral vascular insufficiency (PVI. The combination of these two pathologies is common, with significant repercussions for affected patients. OBJECTIVE: To compare functional limitations and quality of life between patients with HF in isolation or HF + PVI. METHOD: Twelve patients with HF+PVI were paired to 12 patients with HF in isolation. All had ejection fraction 0.05. CONCLUSIONS: The study participants who had mixed disease exhibited a greater degree of functional impairment than the group with HF, without reporting worsened quality of life.

    Of more than 30 species of plants from Egypt screened for sensitivity to ozone, four were found to be suitable for use as bioindicators. - The aim of this study was to test and select one or more highly sensitive, specific and environmentally successful Egyptian bioindicator plants for ozone (O{sub 3}). For that purpose more than 30 Egyptian species and cultivars were subjected to extensive screening studies under controlled environmental and pollutant exposure conditions to mimic the Egyptian environmental conditions and O{sub 3} levels in urban and rural sites. Four plant species were found to be more sensitive to O{sub 3} than the universally used O{sub 3}-bioindicator, tobacco Bel W3, under the Egyptian environmental conditions used. These plant species, jute (Corchorus olitorius c.v. local), clover (Trifolium alexandrinum L. c.v. Masry), garden rocket (Eruca sativa c.v. local) and alfalfa (Medicago sativa L. c.v. local), ranked in order of decreasing sensitivity, exhibited typical O{sub 3} injury symptoms faster and at lower O{sub 3} concentrations than Bel W3. Three variables were tested in search of a reliable tool for the diagnosis and prediction of O{sub 3} response prior to the appearance of visible foliar symptoms: pigment degradation, stomatal conductance (g{sub s}) and net photosynthetic CO{sub 2} assimilation (P{sub net}). Pigment degradation was found to be unreliable in predicting species sensitivity to O{sub 3}. Evidence supporting stomatal conductance involvement in O{sub 3} tolerance was found only in tolerant species. A good correlation was found between g{sub s}, restriction of O{sub 3} and CO{sub 2} influx into the mesophyll tissues, and P{sub net}. Changes in P{sub net} seemed to depend largely on fluctuations in g{sub s}.

    Full Text Available Objective: We aimed to evaluate left ventricular (LV mechanics of patients diagnosed with PsA and no clinical evidence for cardiovascular disease (CVD using a novel, more sensitive technique which evaluates myocardial deformation in multidimensional planes for the detection of impaired LV function. Methods: The study enrolled 31 PsA patients and sex-age matched 19 healthy controls. All participants underwent conventional echocardiography and 2-dimensional speckle tracking echocardiography (STE. Global longitudinal, circumferential, and radial strain were measured. Results: Although patients with PsA had normal LV ejection fraction, the myocardial deformation in multidimensional planes was impaired. STE analysis results showed that PsA patients had significantly lower global longitudinal strain (mean±S.D. -17.11±2.83 % and -19.29±2 % respectively, p=0.005, global circumferential strain (mean±S.D. -14.28±3 % and -20.34±4.78 % respectively p<0.001 and global radial strain (mean±S.D. 29.26±10 % and 46.54±17 % respectively, p<0.001 versus control group. However, no correlation was found between longitudinal, radial, and circumferential strains and disease-related risk factors. Conclusion: Subclinical impaired myocardial deformation was common in patients with PsA even with no clinical evidence for CVD. Thus, the use of this novel imaging technique could provide additional benefits for determining cardiovascular involvement at an early stage and risk stratification in PsA patients.

    Vertigo and dizziness are often not fully explained by an organic illness, but instead are related to psychiatric disorders. This study aimed to evaluate psychiatric comorbidity and assess psychosocial impairment in a large sample of patients with a wide range of unselected organic and non-organic (ie, medically unexplained) vertigo/dizziness syndromes. This cross-sectional study involved a sample of 547 patients recruited from a specialised interdisciplinary treatment centre for vertigo/dizziness. Diagnostic evaluation included standardised neurological examinations, structured clinical interview for major mental disorders (SCID-I) and self-report questionnaires regarding dizziness, depression, anxiety, somatisation and quality of life. Neurological diagnostic workup revealed organic and non-organic vertigo/dizziness in 80.8% and 19.2% of patients, respectively. In 48.8% of patients, SCID-I led to the diagnosis of a current psychiatric disorder, most frequently anxiety/phobic, somatoform and affective disorders. In the organic vertigo/dizziness group, 42.5% of patients, particularly those with vestibular paroxysmia or vestibular migraine, had a current psychiatric comorbidity. Patients with psychiatric comorbidity reported more vertigo-related handicaps, more depressive, anxiety and somatisation symptoms, and lower psychological quality of life compared with patients without psychiatric comorbidity. Almost half of patients with vertigo/dizziness suffer from a psychiatric comorbidity. These patients show more severe psychosocial impairment compared with patients without psychiatric disorders. The worst combination, in terms of vertigo-related handicaps, is having non-organic vertigo/dizziness and psychiatric comorbidity. This phenomenon should be considered when diagnosing and treating vertigo/dizziness in the early stages of the disease. Published by the BMJ Publishing Group Limited.

    Bonaparte's Egyptian Campaign (1798 - 1801), like all other episodes from the Napoleonic era, gave rise to an extensive literature on the subject, but most of all a significant medical literature. This fact is due to many reasons:--an important health service for this expeditionary corps of more than 36.000 men, with two main figures at its hea, Desgenettes and Larrey--but also with valuable subordinates like Assalini, Savaresi, Balme, Pugnet or Barbès.--A Commission for Science and Art, of which a few doctors and surgeons were members, but most of all pharmacists like Boudet or Rouyer--The presence in the field of Ludwig Frank, the nephew of the famous Johann Peter Frank.--The creation in Cairo of an Egyptian Institute and the publication of the masterly Description of Egypt and the establishment of printing houses.--The emergence of the myth of the Orient and its mysteries.--An extensive array of indigenous pathologies, which is characteristic of those countries. For instance: plague, dysentery, yellow fever, Egyptian ophthalmia, as well as more common diseases like tetanus, scurvy or venereal diseases. The main medical works that cover this period and its pathologies are skimmed.

    Objectives: Upright tilt is an important tool for early mobilization of patients after severe acquired brain injury (ABI). Early mobilization is considered to be of importance for increasing awareness, in the prevention of contractures and pulmonary infections and to improve long-term outcome....... A challenge for early mobilization is orthostatic instability that is often observed during heap-up tilt, which could lead to decreased cerebral blood flow velocity (CBFV) and decreased long-term outcome. We examined cerebral blood flow autoregulation in patients with severe brain injury and impaired...

    2011-02-01

    Depression and anxiety have been reported to be independently predictive of conversion to Alzheimer\\'s disease (AD) in patients with mild cognitive impairment (MCI). Anxiety symptoms have been less well studied and findings in this regard have been inconsistent. The objectives of this study are to determine which symptoms among a range of neuropsychiatric symptoms known to commonly occur in patients with MCI are predictive of later conversion to AD. We also wish to determine whether these symptoms track existing measures of declining cognitive and functional status or may be considered distinct and sensitive biomarkers of evolving Alzheimer\\'s pathology.

  20. The relevance of Rawls' principle of justice for research on cognitively impaired patients.

    Maio, Giovanni

    2002-01-01

    An ethical conflict arises when we must perform research in the interest of future patients, but that this may occasionally injure the interests of today's patients. In the case of cognitively impaired persons, the question arises whether it is compatible with humane healthcare not only to treat, but also to use these patients for research purposes. Some bioethicists and theologians have formulated a general duty of solidarity, also pertaining to cognitively impaired persons, as a justification for research on these persons. If one examines this thesis from the theory of justice according to John Rawls, it is revealed that such a duty of solidarity cannot necessarily be extrapolated from Rawls' conception of justice. This is at least true of Rawls' difference principle, because according to the difference principle only those measures are justifiable which serve the interest of the respective least well off. Those measures which would engender additional injury for the least well off could not be balanced by any utility according to Rawls. However, John Rawls' difference principle is subordinate to the first principle, which is that each person has an equal right to the most extensive basic liberty compatible with the same liberty for others. These "primary goods" are determined by the freedom and integrity of the person. This integrity of decisionally impaired persons would be in danger if one would abstain from research and thus forego the increase in knowledge related to their disease. Thus one could conclude, at least from Rawls' first principle, that society must take on a duty to guarantee the degrees of freedom for cognitively impaired persons and thus also support the efforts for their healing.

    This study investigates the possible existence of deficits in familiarity in five samples of participants spanning a broad range of ages and cognitive states. Five groups of 16 participants with a diagnosis of multi-domain cognitive impairment with a slight or no deficit in memory, 16 multi-domain amnestic, and 16 Alzheimer's disease patients were compared in a recognition test with equivalent samples of old and young healthy participants. In one of the tests, participants studied words extracted from a restricted set of letters of the alphabet that were later mixed with new words from a different set. The unconscious use of the fluency produced by the repeated use of the set of letters was compared with a condition in which the same letter set did not play a role. Results indicated that amnestic mild cognitive impaired and Alzheimer's patients were unable to use letter fluency to improve recognition. However, young and old controls did not differ among themselves, whereas the multi-domain sample, whose memory performance was almost at the same level as that of controls showed slight levels of deficit in familiarity in the forced choice test but not in the recognition test. These results contrast sharply with those reported by Westerberg et al. [Westerberg, C. E., Paller, K. E., Holdstock, J. S., Mayes, A. R., & Reber, p. J. (2006). When memory does not fail: Familiarity-based recognition in mild cognitive impairment and Alzheimer's disease. Neuropsychology, 20, 193-205] and Anderson et al. [Anderson, N. D., Ebert, P.

    Oxidative stress constitutes a hallmark of Alzheimer's disease (AD). Recent studies also point to redox active metals such as iron, copper and zinc in mediating oxidative stress in AD pathogenesis. However, the reactivity of cerebrospinal fluid (CSF) iron and its possible correlation with the severity of cognitive decline in both Alzheimer's patients and subjects with mild cognitive impairment (MCI) is still unknown. Here we show that different stages of cognitive and functional impairment are associated with changes in CSF reactive iron. In this work, we compared CSF samples from 56 elders, classified into 4 groups according to their scores on the Clinical Dementia Rating scale (CDR). Total CSF iron was analyzed by atomic absorption spectrometry. Redox-active iron was analyzed by a novel fluorimetric assay. One-way ANOVA was used to test differences in mean values, and Newman-Keuls Multiple Comparison Test was used for multi group comparisons. No difference in total CSF iron was found between different groups. Significant amounts of redox-active iron were found in CSF and their levels correlated with the extent of cognitive impairment. Redox-active CSF iron levels increased with the degree of cognitive impairment from normal to MCI subjects, while AD patients showed an abrupt decrease to levels close to zero. Given the relevance of oxidative damage in neurodegeneration, it might be possible to associate the development of cognitive and functional decline with the presence of redox-active iron in the CSF. The decrease in redox-active iron found in AD patients may represent a terminal situation, whereby the central nervous system attempts to minimize iron-associated toxicity.

    Depression and pain frequently occur together. The objective of this study was to investigate the effects of depression and pain on the impairment of daily functioning and quality of life (QOL) of depressed patients. We enrolled 131 acutely ill inpatients with major depressive disorder. Depression, pain, and daily functioning were assessed using the 17-item Hamilton Depression Rating Scale, the Short-Form 36 (SF-36) Body Pain Index, and the Work and Social Adjustment Scale. Health-related QOL was assessed using three primary domains of the SF-36: social functioning, vitality, and general health perceptions. Pearson׳s correlation and structural equation modeling were used to examine relationships among the study variables. Five models were proposed. In all, 129 patients completed all the measures. Model 5, both depression and pain impaired daily functioning and QOL, was the most fitted structural equation model (χ(2)=9.2, df=8, p=0.33, GFI=0.98, AGFI=0.94, TLI=0.99, CFI=0.99, RMSEA=0.03). The correlation between pain and depression was weak (r=-0.27, z=-2.95, p=0.003). This was a cross-sectional study with a small sample size. Depression and pain exert a direct influence on the impairment of daily functioning and QOL of depressed patients; this impairment could be expected regardless of increased pain, depression, or both pain and depression. Pain had a somewhat separate entity from depression. Copyright © 2014. Published by Elsevier B.V.

    We studied healthy, first-degree relatives of patients with schizophrenia to test the hypothesis that deficits in cognitive skill learning are associated with genetic liability to schizophrenia. Using the Weather Prediction Task (WPT), 23 healthy controls and 10 adult first-degree Relatives Of Schizophrenia (ROS) patients were examined to determine the extent to which cognitive skill learning was automated using a dual-task paradigm to detect subtle impairments in skill learning. Automatization of a skill is the ability to execute a task without the demand for executive control and effortful behavior and is a skill in which schizophrenia patients possess a deficit. ROS patients did not differ from healthy controls in accuracy or reaction time on the WPT either during early or late training on the single-task trials. In contrast, the healthy control and ROS groups were differentially affected during the dual-task trials. Our results demonstrate that the ROS group did not automate the task as well as controls and continued to rely on controlled processing even after extensive practice. This suggests that adult ROS patients may engage in compensatory strategies to achieve normal levels of performance and support the hypothesis that impaired cognitive skill learning is associated with genetic risk for schizophrenia.

    Full Text Available OBJECTIVE: The relationship between brain tumors and cognitive deficits is well established in the literature. However, studies investigating the cognitive status in low and high-grade gliomas patients are scarce, particularly in patients with average or lower educational level. This study aimed at investigating the cognitive functioning in a sample of patients with low and high-grade gliomas before surgical intervention. METHOD: The low-grade (G1, n=19 and high-grade glioma (G2, n=8 patients underwent a detailed neuropsychological assessment of memory, executive functions, visuo-perceptive and visuo-spatial abilities, intellectual level and language. RESULTS: There was a significant impairment on verbal and visual episodic memory, executive functions including mental flexibility, nominal and categorical verbal fluency and speed of information processing in G2. G1 showed only specific deficits on verbal and visual memory recall, mental flexibility and processing speed. CONCLUSION: These findings demonstrated different levels of impairments in the executive and memory domains in patients with low and high grade gliomas.

    Purpose/Background. This study reports the degree of burden and the proportion at risk for depression among individuals who provide care to visually impaired patients. Study Design. This is clinic-based, cross-sectional survey in a tertiary care hospital. Methods. Caregivers were considered unpaid family members for patients whose sole impairment was visual. Patients were stratified by vision in their better seeing eye into two groups: Group 1 had visual acuity between 6/18 and 6/60 and Group 2 were those who had 6/60 or worse. Burden was evaluated by the Burden Index of Caregivers and the prevalence of being at risk for depression was determined by the Center for Epidemiologic Studies Depression scale. Results. 236 caregivers of 236 patients were included. Total mean BIC scores were higher in Group 2. Female caregivers, caregivers providing greater hours of care, and caregivers of patients who have not completed vision rehabilitation programs are at higher risk for depression.

    One hundred and sixty-seven patients with cerebral palsy (CP), aged 11-16 years, with spastic diplegia (n=87) and hemiparetic forms (n=80), with subgroups of mental retardation (MR) or intellectual delay (ID) have been studied. Standard treatment and application of a method of dynamic proprioceptive correction (MDPC) in the complex rehabilitation with the use of a medical and loading Adeli suit were used. Cognitive deficit in patients was characterized by the relative integrity of short-term nonverbal memory and marked impairment of verbal memory, verbal and nonverbal intellect. CP patients with intellectual delay demonstrated the predominant impairment of verbal functions. CP patients with mental retardation have the deficiency of both verbal and non-verbal cognitive functions. An individual profile of brain functional asymmetry in patients with CP was more lateralized than in healthy peers that can represent a mechanism for irregular development of cognitive functions in CP. Implementing the MDPC into comprehensive rehabilitation promotes the improvement of postural regulation and cognitive functions in children with CP compared to traditional methods of treatment. This is accompanied by the changes in functioning of the associative brain areas and hemispheric interaction.

    HIV-associated cognitive impairment occurs even in the early stages of infection. Short-term memory, psychomotor speed, attention, and executive functioning are the main capacities affected. Controversy exists regarding whether highly active antiretroviral therapy (HAART) is helpful in combating this process. The objective of the present study is to determine the association between cognitive impairment and HAART in HIV-infected patients from Hospital Regional de Huacho. Prospective study of HIV patients meeting criteria to start HAART. Twenty-one HIV-positive patients were recruited between April and July 2011. Researchers administered a standardised neuropsychological test battery before and 4 weeks after onset of HAART. Psychomotor speed, executive function, short term memory (visual and verbal), attention, and visuospatial performance were evaluated. Nineteen patients completed the study (14 males and 5 females). In the pre-HAART evaluation, most patients scored below average on the executive function and psychomotor speed subtests. Psychomotor speed and immediate visual memory improved significantly after four months of treatment with HAART. Some degree of cognitive decline may present even in the early and asymptomatic stages of HIV infection. The benefits of antiretroviral treatment for cognitive performance can be detected after only a few weeks of follow-up. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier Espana.

    Examine the relationship among the severity of patient-perceived voice impairment, perceptual dysphonia severity, occupational voice demand, and voice therapy adherence. Identify clinical predictors of increased risk for therapy nonadherence. A retrospective cohort study of patients presenting with a chief complaint of persistent dysphonia at an interdisciplinary voice center was done. The Voice Handicap Index-10 (VHI-10) and the Voice-Related Quality of Life (V-RQOL) survey scores, clinician rating of dysphonia severity using the Grade score from the Grade, Roughness Breathiness, Asthenia, and Strain scale, occupational voice demand, and patient demographics were tested for associations with therapy adherence, defined as completion of the treatment plan. Classification and Regression Tree (CART) analysis was performed to establish thresholds for nonadherence risk. Of 166 patients evaluated, 111 were recommended for voice therapy. The therapy nonadherence rate was 56%. Occupational voice demand category, VHI-10, and V-RQOL scores were the only factors significantly correlated with therapy adherence (P occupational voice demand are significantly more likely to be nonadherent with therapy than those with high occupational voice demand (P 40 is a significant cutoff point for predicting therapy nonadherence (P Occupational voice demand and patient perception of impairment are significantly and independently correlated with therapy adherence. A VHI-10 score of ≤9 or a V-RQOL score of >40 is a significant cutoff point for predicting nonadherence risk. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Full Text Available The study investigates primary and secondary verbal memory and motor/executive functions (response inhibition and strategy shifting ability in multiple sclerosis (MS patients with clinically isolated syndrome (CIS. We studied 44 CIS patients and compared them to 49 patients with relapsing remitting MS (RR-MS displaying mild disability and to a large cohort of age- and education level-matched healthy volunteers (n = 230. Results showed that both CIS and RR-MS patients evidenced a disproportionate impairment in the immediate and delayed recall of the second (as compared to the first of two short narratives of the Logical Memory WMS-III subtest, and reduced performance on the Memory for Digits-Forward. Performance of either group on the executive tasks was not impaired, showing evidence of a reversed speed-accuracy trade-off. Illness duration emerged as a significant predictor of memory and executive task performance. Clinical, psychoemotional, and brain imaging findings were also examined as potential correlates of memory deficits and disease progression among CIS patients. These findings may signify early-onset decline of specific cognitive functions in CIS, which merits regular follow-up assessments and monitoring of psychoemotional adaptation and everyday functioning.

    Full Text Available BACKGROUND: Impaired cognitive flexibility in anorexia nervosa (AN causes clinical problems and makes the disease hard to treat, but its neural basis has yet to be fully elucidated. The purpose of this study was to evaluate the brain activity of individuals with AN while performing a task requiring cognitive flexibility on the Wisconsin Card Sorting Test (WCST, which is one of the most frequently used neurocognitive measures of cognitive flexibility and problem-solving ability. METHODS: Participants were 15 female AN patients and 15 age- and intelligence quotient-matched healthy control women. Participants completed the WCST while their brain activity was measured by functional magnetic resonance imaging during the task. Brain activation in response to set shifting error feedback and the correlation between such brain activity and set shifting performance were analyzed. RESULTS: The correct rate on the WCST was significantly poorer for AN patients than for controls. Patients showed poorer activity in the right ventrolateral prefrontal cortex and bilateral parahippocampal cortex on set shifting than controls. Controls showed a positive correlation between correct rate and ventrolateral prefrontal activity in response to set shifting whereas patients did not. CONCLUSION: These findings suggest dysfunction of the ventrolateral prefrontal cortex and parahippocampal cortex as a cause of impaired cognitive flexibility in AN patients.

    A number of studies have shown that COPD, particularly in its later and more severe stages, is associated with various cognitive deficits. Thus, the primary goal of the present study was to elucidate the extent of cognitive impairment in patients with long-term oxygen therapy-dependent (LTOTD) COPD. In addition, this study aimed to determine the effectiveness of two cognitive screening tests, the Mini-Mental State Examination (MMSE) and the Montreal Cognitive Assessment (MoCA), for COPD patients and the ability of oxygen therapy to mitigate COPD-related deficits in cognitive function. The present study enrolled 45 subjects: 24 nonuser and 21 regular-user LTOTD-COPD patients. All subjects had a similar grade of education, and there were no significant differences regarding age or sex. The MoCA (cutoff: therapy increased the risk of cognitive impairment (MoCA, P=0.007 and MMSE, P=0.014), and the MoCA and MMSE scores significantly correlated with the number of emergency admissions and the number of hospitalizations in the last year. In the present study, the nonuser LTOTD-COPD group exhibited a significant decrease in cognitive status compared with the regular-user LTOTD-COPD group. This suggests that the assessment of cognitive function in nonuser LTOTD-COPD patients and the use of protective strategies, such as continuous supplemental oxygen treatment, should be considered during the management of COPD in this population. In addition, the MoCA score was superior to the MMSE score for the determination of cognitive impairment in the nonuser LTOTD-COPD patients.

    Traditional risk factors for cardiovascular diseases have been shown to have an even higher impact in the HIV infected population. Cardiovascular risk factors amongst people living with HIV treated in doctor's offices in Austria have not been documented before. Our study aimed to close this gap, focusing on dyslipidemia, diabetes mellitus and diabetes risk. After ethics approval, consecutive patients who visited their treating physicians for routine checks were enrolled. The lipid profile was assessed by measuring total cholesterol, triglycerides, HDL and apolipoprotein B and calculating LDL and non-HDL-cholesterol. The diabetes risk was calculated by measuring insulin and blood glucose levels and assessing insulin resistance and beta cell function using the HOMA-IR model. 522 patients were included in the analysis. 90.2% of the participants were on antiretroviral therapy. Two third had an impaired lipid profile, but dyslipidemia had been diagnosed only in 46.3% of the patients. There was a clear correlation between protease inhibitor use and pathologic blood lipids. Of the persons with dyslipidemia, 18.4% received lipid lowering drugs. 8 persons (1.6%) fulfilled the criteria for diabetes mellitus. Of those, 4 patients already had a diagnosed diabetes mellitus. 50.1% of the study participants showed an increased insulin resistance. Patients on nucleoside reverse transcriptase inhibitors had significantly higher markers for impaired glucose metabolism. We found a high percentage of increased insulin resistance, of impaired lipid profile and in contrast to this a low treatment rate with lipid lowering drugs in this cohort of people living with HIV.

    Standard markers in cerebrospinal fluid (CSF), as soluble amyloid beta 1-42 (Abeta1-42) and total tau protein (t-tau), may contribute to dementia subtypes diagnostic accuracy. Yet, their sensitivity to assess the different degree of cognitive deficit is not fully clarified. Our study analyses Abeta1-42 and t-tau CSF levels in different cohorts of Alzheimer's disease (AD) patients, distinguished as early AD (mild cognitively impaired subjects recently converted to AD), mild AD (MMSE or =18), and moderately advanced AD (MMSEstage. In early AD patients, Abeta1-42 levels were already significantly low, if compared to the control group (336 vs 867 ng/L; pdiffer between AD subgroups, and in particular between mild to moderate AD. A significant progressive increase of t-tau concentration was found when comparing early AD (269 ng/L) to more advanced AD stages (468 ng/L and 495 ng/L for mild and moderate AD, respectively). Our findings confirm that the impairment of amyloidogenic cascade is an early, even pre-clinical process, but suggest that soluble Abeta1-42 concentration has a negligible correlation with the clinical progression. Conversely, t-tau concentration correlates with the transition towards marked cognitive impairment.

    Intensive care unit (ICU) admission is associated with muscle weakness and ICU survivors report sustained limitation of physical capacity for years after discharge. Limited information is available on the underlying biomechanical properties responsible for this muscle function impairment....... A plausible contributor to the accentuated catabolic drive in ICU patients is a synergistic response to inflammation and inactivity leading to loss of muscle mass. As these entities are predominantly present in the early phase of ICU stay, interventions employed during this time frame may exhibit the greatest...... potential to counteract loss of muscle mass. Despite the obvious clinical significance of muscle atrophy for the functional impairment observed in ICU survivors, no preventive therapies have been identified as yet. The overall aim of the present dissertation is to characterize aspects of physical function...

    Full Text Available BACKGROUND: It has been estimated that Nursing Home (NH residents with impaired cognitive status receive an average of seven to eight drugs daily. The aim of this study was to determine prevalence and factors associated with use of inappropriate drugs in elderly patients with severe cognitive impairment living in NH in Europe. METHODS: Cross-sectional data from a sample of 1449 NH residents with severe cognitive impairment, participating in the Services and Health for Elderly in Long TERm care (SHELTER study were analysed. Inappropriate drug use was defined as the use of drugs classified as rarely or never appropriate in patients with severe cognitive impairment based on the Holmes criteria published in 2008. RESULTS: Mean age of participating residents was 84.2±8.9 years, 1087 (75.0% were women. Inappropriate drug use was observed in 643 (44.9% residents. Most commonly used inappropriate drugs were lipid-lowering agents (9.9%, antiplatelet agents (excluding Acetylsalicylic Acid - ASA - (9.9%, acetylcholinesterase, inhibitors (7.2% and antispasmodics (6.9%. Inappropriate drug use was directly associated with specific diseases including diabetes (OR 1.64; 95% CI 1.21-2.24, heart failure (OR 1.48; 95% CI 1.04-2.09, stroke (OR 1.43; 95% CI 1.06-1.93, and recent hospitalization (OR 1.69; 95% CI 1.20-2.39. An inverse relation was shown between inappropriate drug use and presence of a geriatrician in the facility (OR 0.55; 95% CI 0.39-0.77. CONCLUSION: Use of inappropriate drugs is common among older EU NH residents. Determinants of inappropriate drug use include comorbidities and recent hospitalization. Presence of a geriatrician in the facility staff is associated with a reduced rate of use of these medications.

    It is unclear whether cerebral blood flow responses to hypoglycemia are altered in people with type 1 diabetes and impaired awareness of hypoglycemia. The aim of this study was to investigate the effect of hypoglycemia on both global and regional cerebral blood flow in type 1 diabetes patients with impaired awareness of hypoglycemia, type 1 diabetes patients with normal awareness of hypoglycemia and healthy controls ( n = 7 per group). The subjects underwent a hyperinsulinemic euglycemic-hypoglycemic glucose clamp in a 3 T MR system. Global and regional changes in cerebral blood flow were determined by arterial spin labeling magnetic resonance imaging, at the end of both glycemic phases. Hypoglycemia generated typical symptoms in patients with type 1 diabetes and normal awareness of hypoglycemia and healthy controls, but not in patients with impaired awareness of hypoglycemia. Conversely, hypoglycemia increased global cerebral blood flow in patients with impaired awareness of hypoglycemia, which was not observed in the other two groups. Regionally, hypoglycemia caused a redistribution of cerebral blood flow towards the thalamus of both patients with normal awareness of hypoglycemia and healthy controls, consistent with activation of brain regions associated with the autonomic response to hypoglycemia. No such redistribution was found in the patients with impaired awareness of hypoglycemia. An increase in global cerebral blood flow may enhance nutrient supply to the brain, hence suppressing symptomatic awareness of hypoglycemia. Altogether these results suggest that changes in cerebral blood flow during hypoglycemia contribute to impaired awareness of hypoglycemia.

  20. Decision-Making Impairments in Patients with Parkinson’s Disease

    2004-01-01

    Full Text Available A high percentage of Parkinson’s disease (PD patients show cognitive impairments in addition to the cardinal motor symptoms. These deficits primarily concern executive functions most probably linked to dysfunctions in prefrontal regions due to decreased dopaminergic transmission in fronto-striatal loops. To investigate possible associations between decision-making and executive functions in PD, we examined 20 non-demented PD patients and 20 healthy control subjects with a neuropsychological test battery and the Game of Dice Task. In this computerised decision-making task, the rules for gains and losses and the winning probabilities are obvious and stable. Thus, strategic components besides feedback processing might influence decision-making in this task. We found that PD patients were impaired in the Game of Dice task performance and that the frequency of disadvantageous choices correlated with both executive functions and feedback processing. We suggest that decision-making deficits of PD patients in explicit gambling situations might be associated with dysfunctions in two different fronto-striatal loops: the limbic-orbitofrontal-striatal loop, involved in feedback processing, and the dorsolateral prefrontal-striatal loop, involved in executive functions.

    Full Text Available Neurocognitive impairment is a detrimental complication of HIV infection. Here, we characterized the intellectual performance of patients with newly diagnosed HIV infection in southwestern Nigeria. We conducted a prospective study at Owo Federal Medical Center by using the adapted Wechsler Adult Intelligence Scale (WAIS. The raw scores were converted to standardized scores (z-scores and correlated with clinical and laboratory findings. Fifty-eight HIV positive patients were recruited; 72% were in WHO stages 3 and 4. We detected a high rate of intellectual impairment in HIV positive patients and controls (63.8% and 10%, resp.; P<0.001. HIV positive patients performed worse throughout the subtests of both verbal and performance intelligence quotients. Presence of opportunistic infections was associated with worse performance in the similarities and digit symbol tests and performance and full scale scores. Lower body weight correlated with poor performance in different WAIS subtests. The high rate of advanced disease stage warrants measures aimed at earlier diagnosis and treatment. Assessment of neurocognitive performance at diagnosis may offer the opportunity to improve functioning in daily life and counteract disease progression.

    Acid-basic balance (ABB) is the important element that supports local homeostasis in oral cavity (OC). However dentists usually do not take into account ABB in OC thus reducing the efficiency of dental care and treatment of mucous membrane disorders in these patients. The purpose of the research was to estimate the ABB values in OC in patients having chronic general somatic diseases. The ABB in OC in 80 healthy persons and in 289 persons with ulcer disease, chronic kidneys insufficiency or insulin-dependent diabetes aged 35-44 years was assessed. The speed of no stimulus salivation, рН of oral and gingival liquids as well as amplitude tests (saccharose and carbamide) curves рН were evaluated. Patients with a somatic pathology have an impairment of OC ABB regulation system associated with changes of acid- and ammonia-producing microflora activity, topographical redistribution of functional acidosis and alkalosis zones. Correction of the revealed impairments is necessary to increase the efficiency of dental care and preventive treatment in these groups of patients.

    Objective: Diffuse brain atrophy has been observed in cirrhotic patients and recent reports have revealed the persistence of cognitive impairment after clinical resolution of overt hepatic encephalopathy. We sought to explore the continued influence of overt hepatic encephalopathy on neurological function by measuring brain resting-state inherent connectivity, based on an investigation of structural abnormalities. Methods: Neuropsychological tests and structural and functional magnetic resonance scanning were conducted in 20 healthy controls and 21 cirrhotic patients with a history of overt hepatic encephalopathy. The analysis of voxel-based morphometry and functional connectivity were performed to detect the alterations in brain structure and function, respectively. Results: Patients showed significantly worse performance in neuropsychological tests as compared with controls, despite apparently normal mental status. Analysis of voxel-based morphometry revealed a decrease in gray matter volume primarily in the midline regions, bilateral insular cortex and caudates, left parahippocampal gyrus, and right cerebellum posterior lobe, while the volume of the bilateral thalamus showed an increase. Of these regions, the posterior cingulate cortex with peak atrophy was selected as the origin for the analysis of functional connectivity. Typical patterns of a default mode network were identified in both groups. Decreased functional connectivity was found in the medial prefrontal gyrus, left inferior parietal lobule, and left middle temporal gyrus in the patients. Conclusions: Both functional and structural impairments were evident after apparent recovery from overt hepatic encephalopathy, demonstrating that brain dysfunction induced by hepatic encephalopathy persisted after clinical resolution and provided a basis for further evolution of the disease.

    Peritoneal dialysis (PD) exchange procedure is complex. Patients with cognitive impairment (CI) may require assistance. We studied the prevalence of CI among PD patients, its impact on PD-related peritonitis and the outcome of assisted PD. Cantonese version of Mini-Mental State examination (CMMSE) was performed in 151 patients newly started on PD. Data on patient characteristics including demographics, co-morbidities, blood parameters, medications, and number of PD-related peritonitis in the first 6 months were collected. 151 subjects were recruited. The age of studied patients was 60 ± 15.0 years, and 45% were female. The prevalence of CI was 13.9% using education-adjusted cut-off of CMMSE. Patients older than 65-year-old, female, and lower education level were independent risk factors for CI (OR 9.27 p = 0.001, OR 14.84 p = 0.005, and OR 6.10 p = 0.009, respectively). Age greater than 65-year old is an independent risk factor for PD-related peritonitis but CI was not. Patients requiring assisted PD were of older age (p peritonitis (p = 0.07). CI is common among local PD patients. Overall, CI could not be identified as an independent risk factor for PD peritonitis. There is a higher prevalence of CI among assisted PD patients but helpers may not completely eliminate the risk of PD-related peritonitis.

    Increased sympathetic activation is a key modifier for arrhythmogenesis in patients with long QT syndrome (LQTS), a congenital channelopathy. Therefore, we investigated cardiac sympathetic function using {sup 123}I-metaiodobenzylguanidine (MIBG) single photon emission computed tomography (SPECT) in a cohort of symptomatic LQTS patients and correlated these findings with the underlying genotype. [{sup 123}I]MIBG SPECT was performed in 28 LQTS patients. Among these, 18 patients (64%) had a previous syncope and 10 patients (36%) survived sudden cardiac arrest. Patients were characterized in terms of genetic subtypes and QTc interval on surface ECGs. SPECT images were analysed for regional [{sup 123}I]MIBG uptake in a 33-segment bullseye scheme and compared to those obtained from 10 age-matched healthy control subjects (43 {+-} 12 years). An abnormal {sup 123}I-MIBG scan was found in 17 of 28 LQTS patients (61%) with a tracer reduction mainly located in the anteroseptal segments of the left ventricle. This finding was independent of the genetic LQTS subtype. In addition, no differences were found between LQTS patients with a QTc >500 ms vs <500 ms or those suffering from syncope vs VF (p > 0.05). A distinct regional pattern of impaired cardiac sympathetic function was identified in the majority of symptomatic LQTS patients. This innervation defect was independent of the underlying genotype and clinical disease expression. (orig.)

    Full Text Available In Parkinson's disease (PD, several studies have detected an impaired serotonin (5-HT pathway, likely affecting both motor and non-motor domains. However, the precise impact of 5-HT impairment is far from established. Here, we have used a HPLC chromatographic method, in a homogenous cohort (n = 35 of non fluctuating, non dyskinetic PD patients, to assess the concentration of 5-HT and its metabolite 5-HIAA in peripheral cerebrospinal fluid (CSF obtained from lumbar puncture (LP. LP was performed following three days of therapy withdrawal, in order to vanish the effects of prolonged released dopamine agonists (DA, and in absence of any serotonergic agent. The PD patient group showed a significantly reduced CSF level of both 5-HT and 5-HIAA compared to either age-matched control subjects (n = 18, or Alzheimer's disease patients (n = 20. However, no correlation emerged between 5-HT/5-HIAA concentrations and UPDRS-III (r = -0.12, disease duration (r = -0.1, age (r = -0.27 and MMSE (r = 0.11. Intriguingly, low CSF 5-HT levels did not differ for gender or for motor phenotype (in terms of non-tremor dominant subtype and tremor dominant subtype. Further, low CSF 5-HT levels did not correlate with the presence of depression, apathy or sleep disturbance. Our findings support the contention that 5-HT impairment is a cardinal feature of stable PD, probably representing a hallmark of diffuse Lewy bodies deposition in the brainstem. However, clinical relevance remains uncertain. Given these findings, an add-on therapy with serotonergic agents seems questionable in PD patients, or should be individually tailored, unless severe depression is present.

    Background:Patients with Alzheimer's disease (AD) manifest progressive decline in writing abilities.Most studies on agraphia in AD have been performed in the alphabetic system,such as English.However,these findings may not be applicable to other written language systems.The unique features of the Chinese written script could affect the patterns of agraphia in Chinese AD patients.The aim of this study was to explore the features of writing errors in Chinese patients with AD and amnestic mild cognitive impairment (a-MCI),as well as to study the relationship between their writing errors and neuropsychological functions.Methods:In this study,we performed an observational study in a group of subjects including 17 AD patients,14 patients with a-MCI,and 16 elderly healthy controls.We analyzed the writing errors in these subjects and also studied the relationship between their writing errors and neuropsychological functions.Results:Our study showed that in patients whose mother tongue is Chinese,writing ability was comparatively well preserved in the MCI phase but significantly impaired when the disease progressed to the stage of AD.The writing errors showed corresponding increase with the severity of cognition decline,both in the types of errors and rate of occurrence.Analysis of the writing errors showed that word substitution and unintelligible words were the most frequent error types that occurred in all the three study groups.The occurrence rate of unintelligible words was significantly higher in the AD group compared with the a-MCI group (P =0.024) and control group (P =0.018).In addition,the occurrence rates of word substitution were also significantly higher in AD (P =0.013) and a-MCI groups (P =0.037) than that of control group.However,errors such as totally no response,visuospatial impairment,paragraph agraphia,ideograph,and perseverative writing errors were only seen in AD group.Besides,we also found a high occurrence rate of visuoconstructional errors (13.3

    Impaired foot function may jeopardize the mobility of patients with rheumatoid arthritis (RA). However, there are still no guidelines concerning the adequate early treatment of painful rheumatoid feet which do not yet require surgery. An assessment method for RA feet appears necessary in order to detect foot problems before functional limitations develop. Therefore, the aim of the present study was to evaluate the use of pedobarographic measurements for detecting changes in plantar loading characteristics and their relationship to foot pain in patients with RA. One hundred and twelve patients with RA (55.0+/-11.0 years of age) were divided into three groups according to their Health Assessment Questionnaire (HAQ) Score and compared to a control group of 20 healthy adults (CG). Thirty-six patients with good physical capacity belonged to group 1 (RA1; HAQ-score: 0-1.0), 38 patients with moderate capacity to group 2 (RA2; score: 1.1-2.0) and 38 patients with low capacity to group 3 (RA3; score: 2.1-3.0). Each patient's foot pain was clinically assessed. Pedobarography was used to analyze foot loading parameters while walking barefoot. In the forefoot, average pressures under the lateral forefoot were higher in RA1 patients than in RA2 patients and controls (phead (p<0.05). In contrast, no significant differences in maximum force could be demonstrated between patient groups. Furthermore, in RA3 patients with lower physical capacity, foot pain was increased as compared to RA1 and RA2 patients. In RA patients, pedobarographic patterns show specific changes which characterize the level of functional capacity. In patients with foot involvement, pedobarographic measurements can be useful during the earlier stages of the disease, when clinical examination does not yet indicate the need for more aggressive treatment or orthopedic interventions.

    Our aim was to develop and validate the Spanish version of the Amyotrophic Lateral Sclerosis Cognitive Behavioural Screen (ALS-CBS) and investigate behavioural/cognitive impairment in our ALS patients. We enrolled 50 patients with definite or probable ALS, evaluated by the Motor Neuron Disease Unit (using El Escorial criteria) and Dementia Unit, and assessed with the Spanish ALS-CBS. The patients' cognitive/behavioural status was classified according to current criteria. Patients were classified into each diagnostic category: ALS-no impairment, 36%; ALS-mild cognitive impairment, 34%; ALS-mild behavioural impairment, 6%; ALS-mild cognitive/behavioural impairment, 12%; ALS-frontotemporal dementia, 12%. Cognitive impairment was more common in bulbar (90.9%) than spinal (48.7%) forms (p CBS was validated. Performance to differentiate normal vs. impaired individuals was: 1) cognition (cut-off 15; AUC, 84.7%): sensitivity 86.2%, specificity 62%, positive predictive value 75.8%, negative predictive value 76.5%; 2) behaviour (cut-off 36; AUC, 83.3%): sensitivity 93.3%, specificity 74.3%, positive predictive value 61%, negative predictive value 96.3%. Performance to differentiate between patients with and without dementia: 1) cognition (cut-off 8; AUC, 87.3%): sensitivity 83.3%, specificity 75%, positive predictive value 31.3%, negative predictive value 97.1%; 2) behaviour (cut-off 35; AUC, 80.9%): sensitivity 83.3%, specificity 69%, positive predictive value 25%, negative predictive value 96.7%. In conclusion, cognitive impairment is common in ALS patients, particularly in bulbar forms. The Spanish version of the ALS-CBS is useful for screening cognitive/behavioural impairment in this population.

    Full Text Available Amyotrophic lateral sclerosis (ALS is a severe neurodegenerative disease with a compli-cated and poorly understood pathogenesis. Recently, alterations in the blood-Central Nervous System barrier (B-CNS-B have been recognized as a key factor possibly aggravating motor neuron damage. The majority of findings on ALS microvascular pathology have been deter-mined in mutant SOD1 rodent models, identifying barrier damage during disease develop-ment which might similarly occur in familial ALS patients carrying the SOD1 mutation. However, our knowledge of B-CNS-B competence in sporadic ALS (SALS has been limited. We recently showed structural and functional impairment in postmortem gray and white mat-ter microvessels of medulla and spinal cord tissue from SALS patients, suggesting pervasive barrier damage. Although numerous signs of barrier impairment (endothelial cell degenera-tion, capillary leakage, perivascular edema, downregulation of tight junction proteins, and microhemorrhages are indicated in both mutant SOD1 animal models of ALS and SALS pa-tients, other pathogenic barrier alterations have as yet only been identified in SALS patients. Pericyte degeneration, perivascular collagen IV expansion, and white matter capillary abnor-malities in SALS patients are significant barrier related pathologies yet to be noted in ALS SOD1 animal models. In the current review, these important differences in blood-CNS barrier damage between ALS patients and animal models, which may signify altered barrier transport mechanisms, are discussed. Understanding discrepancies in barrier condition between ALS patients and animal models may be crucial for developing effective therapies.

    To evaluate driving performance and psychomotor vigilance in patients with primary insomnia. After 1 night of polysomnography, participants performed a 1-h simulated monotonous driving task and a psychomotor vigilance task (PVT). Self-ratings of sleepiness, mood, and driving performance were completed. This study was conducted at the CHU of Caen Sleep Unit and the University of Caen. Twenty-one primary insomnia patients and 16 good sleepers. Not applicable. Results revealed a larger standard deviation of lateral position (P = 0.023) and more lane crossings (P = 0.03) in insomnia patients than in good sleepers. Analyses of effect of time on task performance showed that the impairment in patients occurred after 20 min of driving, which was not the case for good sleepers. No difference between groups was found for the PVT, neither for the mean reaction time (RT) (P = 0.43) nor the number of lapses (P = 0.21) and the mean slowest 10% 1/RT (P = 0.81). Patients rated their sleepiness level higher (P = 0.06) and their alertness level lower (P = 0.007) than did good sleepers (P = 0.007). The self-evaluation of the driving performance was not different between groups (P = 0.15). These findings revealed that primary insomnia is associated with a performance decrement during a simulated monotonous driving task. We also showed that patients are able to drive safely only for a short time. It appears advisable for clinicians to warn patients about their impaired driving performance that could lead to an increased risk of driving accidents. © 2014 Associated Professional Sleep Societies, LLC.

    Full Text Available Abstract Background Patients with diabetes mellitus (DM have high risk of heart failure. Whether some of the risk is directly linked to metabolic derangements in the myocardium or whether the risk is primarily caused by coronary artery disease (CAD and hypertension is incompletely understood. Echocardiographic tissue Doppler imaging was therefore performed in DM patients without significant CAD to examine whether DM per se influenced cardiac function. Methods Patients with a left ventricular (LV ejection fraction (EF > 35% and without significant CAD, prior myocardial infarction, cardiac pacemaker, atrial fibrillation, or significant valve disease were identified from a tertiary invasive center register. DM patients were matched with controls on age, gender and presence of hypertension. Results In total 31 patients with diabetes and 31 controls were included. Mean age was 58 ± 12 years, mean LVEF was 51 ± 7%, and 48% were women. No significant differences were found in LVEF, left atrial end systolic volume, or left ventricular dimensions. The global longitudinal strain was significantly reduced in patients with DM (15.9 ± 2.9 vs. 17.7 ± 2.9, p = 0.03, as were peak longitudinal systolic (S' and early diastolic (E' velocities (5.7 ± 1.1 vs. 6.4 ± 1.1 cm/s, p = 0.02 and 6.1 ± 1.7 vs. 7.7 ± 2.0 cm/s, p = 0.002. In multivariable regression analyses, DM remained significantly associated with impairments of S' and E', respectively. Conclusion In patients without significant CAD, DM is associated with an impaired systolic longitudinal LV function and global diastolic dysfunction. These abnormalities are likely to be markers of adverse prognosis.

    The objective of the present study was to evaluate the pharmacokinetics of tilidine (CAS 20380-58-9), naloxone (CAS 465-65-6) and tilidine metabolites after administration of a single oral dose of a solution containing 100 mg tilidine hydrochloride and 8 mg naloxone hydrochloride (equivalent to 1.44 ml Valoron N solution) to patients with severe hepatic impairment. The investigation was carried out as an open single-dose study in 8 patients suffering from liver cirrhosis. Patients qualified for study enrollment if they had a Child-Pugh score of > or = 7 and a mono-ethyl-glycine-xylidide (MEGX) 15-min test value < 50 ng/ ml. Blood samples were taken over a period of 28 h and analyzed for the prodrug tilidine, its active metabolite nortilidine, bisnortilidine, and naloxone (total and non-glucuronidated fraction). Pharmacokinetic parameters were compared with data from a previous study performed in healthy volunteers. Tilidine, nortilidine and unconjugated naloxone pharmacokinetic parameters showed a high variability between patients. Compared to previous results obtained in healthy volunteers, maximum plasma concentration (Cmax) of nortilidine was reduced by 44%, whereas elimination half-life (t1/2) was prolonged by factor 2. The area under the curve (AUC) showed a slight reduction of approximately 20%. For total naloxone, no relevant change was observed. However, in contrast to the results obtained in healthy subjects, unconjugated naloxone could be measured in plasma from patients with cirrhosis, possibly due to a reduced glucuronidation capacity of the liver in these patients. In conclusion, severe hepatic impairment has a relatively minor influence on the exposure (AUC) to the active metabolite of tilidine (i.e., nortilidine). However, a straightforward interpretation of the results was confounded by pronounced variability in nortilidine pharmacokinetics. In individual patients with severely affected liver function, satisfactory analgesia with tilidine

Thus, the primary goal of the present study was to elucidate the extent of cognitive impairment in patients with long-term oxygen therapy-dependent (LTOTD COPD. In addition, this study aimed to determine the effectiveness of two cognitive screening tests, the Mini-Mental State Examination (MMSE and the Montreal Cognitive Assessment (MoCA, for COPD patients and the ability of oxygen therapy to mitigate COPD-related deficits in cognitive function. Methods: The present study enrolled 45 subjects: 24 nonuser and 21 regular-user LTOTD-COPD patients. All subjects had a similar grade of education, and there were no significant differences regarding age or sex. The MoCA (cutoff: <26 points and MMSE (cutoff: ≤24 points scores were compared between these two groups.Results: The nonuser LTOTD-COPD group had a significantly lower MoCA score than that of the regular-user LTOTD-COPD group (19.38±2.99 vs 21.68±2.14, respectively as well as a significantly lower MMSE score. Moreover, the absence of supplemental oxygen therapy increased the risk of cognitive impairment (MoCA, P=0.007 and MMSE, P=0.014, and the MoCA and MMSE scores significantly correlated with the number of emergency admissions and the number of hospitalizations in the last year.Conclusion: In the present study, the nonuser LTOTD-COPD group exhibited a significant decrease in cognitive status compared with the regular-user LTOTD-COPD group. This suggests that the assessment of cognitive function in nonuser LTOTD-COPD patients and the use of protective strategies, such as

    Full Text Available Acute cerebrovascular disease is a global medical and social problem of the modern angioneurology, occupying leading positions in the structure of morbidity and mortality among adult population of the world. Ischemic stroke – is one of the most common pathology. Today this disease took out the world pandemic. More than 16 million new cases of cerebral infarction recorded in the world each year and it “kills” about 7 million of people. About 111,953 cases of cerebral stroke were registered in 2013 in Ukraine. Cognitive impairment, t hat significantly disrupt daily activities and life of the patient, is one of the most significant post-stroke complications that have social, medical and biological significance. Aim. The purpose of this investigation was to study features and dynamics of cognitive impairments in patients with primary and recurrent cerebral hemispheric ischemic stroke (CHIS in the acute stage of the disease. Materials and methods. To achieve the aim, and the decision of tasks in the clinic of nervous diseases Zaporozhye State Medical University (supervisor - Doctor of Medicine, Professor Kozelkin A. based on the department of acute cerebrovascular disease were performed comparative, prospective cohort study, which included comprehensive clinical and paraclinical examinations of 41 patients (26 men and 15 women aged 45 to 85 years (mean age 66,4 ± 1,4 years with acute left-hemispheric (2 patients and right - hemispheric (39 patients CHIS . First up was a group of 28 patients (19 men and 9 women, mean age 65,6 ± 1,6 years, who suffered from primary CHIS. The second group consisted of 13 patients (7 men and 6 women, mean age 68,1 ± 2,5 years with recurrent CHIS. The groups were matched by age, sex, localization of the lesion and the initial level of neurological deficit. All patients underwent physical examination, neurological examination.

    Bioavailability of clopidogrel in the form of crushed tablets administered via nasogastric tube (NGT) has not been established in patients after cardiopulmonary resuscitation. Therefore, we performed a study comparing pharmacokinetic and pharmacodynamic response to high loading dose of clopidogrel in critically ill patients after cardiopulmonary resuscitation (CPR) with patients scheduled for elective coronary angiography with stent implantation. In the NGT group (nine patients, after cardiopulmonary resuscitation, mechanically ventilated, therapeutic hypothermia), clopidogrel was administered in the form of crushed tablets via NGT. Ten patients undergoing elective coronary artery stenting took clopidogrel per os (po) in the form of intact tablets. Pharmacokinetics of clopidogrel was measured with high-performance liquid chromatography (HPLC) before and at 0.5, 1, 6, 12, 24 h after administration of a loading dose of 600 mg. In five patients in each group, antiplatelet effect was measured with thrombelastography (TEG; Platelet Mapping) before and 24 h after administration. The carboxylic acid metabolite of clopidogrel was detected in all patients in the po group. In eight patients, the maximum concentration was measured in the range of 0.5-1 h after the initial dose. In four patients in the of NGT group, the carboxylic acid metabolite of clopidogrel was undetectable and in the remaining patients was significantly delayed (peak values at 12 h). All patients in the po group reached clinically relevant (>50 %) inhibition of thrombocyte adenosine diphosphate (ADP) receptor after 24 h compared with only two in the NGT group (p = 0.012). There was a close correlation between peak of inactive clopidogrel metabolite plasmatic concentration and inhibition of the ADP receptor (r = 0.79; p < 0.001). The bioavailability of clopidogrel in critically ill patients after cardiopulmonary resuscitation is significantly impaired compared with stable patients. Therefore

    Full Text Available Abstract Background The course and outcomes of hip fracture patients are often complicated by the presence of dementia and delirium, referred to as cognitive impairment (CI, which limits access to in-patient rehabilitation. In response to this concern, members of our team developed and piloted an in-patient rehabilitation model of care (Patient-Centred Rehabilitation Model; PCRM targeting patients with hip fracture and CI (PCRM-CI. We are now conducting a 3-year study comparing an inpatient rehabilitation model of care for community dwelling individuals with hip fracture and CI (PCRM-CI to usual care to determine whether it results in improved mobility at the time of discharge from inpatient rehabilitation. Methods/Design A non-equivalent pre-post design is being used to evaluate the PCRM-CI compared to usual care. All community dwelling (private home or retirement home patients following a hip fracture are eligible to participate. Recruitment of both cohorts is taking place at two facilities. Target accrual is 70 hip fracture patients in the PCRM-CI cohort and 70 patients in the usual care cohort. We are also recruiting 70 health care providers (HCPs, who are being trained to implement the PCRM-CI, and their unit managers. Patient data are collected at baseline, discharge, and 6 months post-discharge from an inpatient rehabilitation program. Evaluations include mobility, physical function, and living arrangement. Additional outcome variables are being collected from medical records and from the patients via their proxies. Data on the prevalence and severity of dementia and delirium are being collected. Staff data are collected at baseline and one year after implementation of the model to determine change in staff knowledge and attitudes toward patients with hip fracture and CI. Bi-monthly semi-structured interviews with unit managers have been conducted to examine factors and barriers influencing the model implementation. Data collection

    Previous studies of patients with Alzheimer's disease (AD) have described reduced brain serotonin 2A (5-HT(2A)) receptor density. It is unclear whether this abnormality sets in early in the course of the disease and whether it is related to early cognitive and neuropsychiatric symptoms. We assessed...... cerebral 5-HT(2A) receptor binding in patients with mild cognitive impairment (MCI) and related 5-HT(2A) receptor binding to clinical symptoms.

    Background Caregivers of patients with mild cognitive impairment (MCI) need similar levels of support services as Alzheimer’s disease (AD) caregivers, but it is unclear if this translates to increased caregiver burden. Methods 135 participants and their caregivers (40 MCI, 55 AD and 40 normal controls, NC) completed questionnaires, and the patients were administered neuropsychological tests. Results The MCI caregivers reported significantly more overall caregiving burden than the NC, but less than the AD. They showed similar levels of emotional, physical and social burden as the AD caregivers. Among the MCI caregivers, the neuropsychiatric symptoms and executive functioning of the patients were related to a greater burden, and the caregivers with a greater burden reported lower life satisfaction and social support, and a greater need for support services. Conclusion These results indicate that MCI caregivers are at increased risk for caregiver stress, and they require enhanced assistance and/or education in caring for their loved ones. PMID:23128102

    The Walking Impairment Questionnaire (WIQ) is a frequently used questionnaire to evaluate patients with intermittent claudication on four subscales: pain severity, walking distance, walking speed and the ability to climb stairs. The aim of this study is to translate and validate the WIQ in Chinese. After translation and cultural adaptation of the WIQ, 134 patients with intermittent claudication completed the Chinese WIQ and European Quality of Life 5 Dimension (EQ-5D). Walking distances were determined by the 6-minute walk test (6MWT). Correlations between the WIQ, quality of life questionnaire and walking distances were calculated to determine validity. Reliability and internal consistency were determined using the intra-class correlation coefficient (ICC) and Cronbach's alpha (α), respectively. Significant correlations were found between the WIQ score, initial claudication distance (ICD), absolute claudication distance (ACD) and all domains of the EQ-5D (all p ≤ 0.01). Test-retest reliability (ICC = 0.74) and the overall internal consistency determined (α = 0.90) showed good agreement. A lower WIQ score corresponded to shorter walking distances. In conclusion, this study showed that the Chinese version of the WIQ is a valid, reliable and clinically relevant instrument for assessing walking impairment in patients with intermittent claudication.

    Impairments in the ability to recognize and attribute emotional states to others have been described in amyotrophic lateral sclerosis patients and linked to the dysfunction of key nodes of the emotional empathy network. Microstructural correlates of such disorders are still unexplored. We investigated the white-matter substrates of emotional attribution deficits in a sample of amyotrophic lateral sclerosis patients without cognitive decline. Thirteen individuals with either probable or definite amyotrophic lateral sclerosis and 14 healthy controls were enrolled in a Diffusion Tensor Imaging study and administered the Story-based Empathy Task, assessing the ability to attribute mental states to others (i.e., Intention and Emotion attribution conditions). As already reported, a significant global reduction of empathic skills, mainly driven by a failure in Emotion Attribution condition, was found in amyotrophic lateral sclerosis patients compared to healthy subjects. The severity of this deficit was significantly correlated with fractional anisotropy along the forceps minor, genu of corpus callosum, right uncinate and inferior fronto-occipital fasciculi. The involvement of frontal commissural fiber tracts and right ventral associative fronto-limbic pathways is the microstructural hallmark of the impairment of high-order processing of socio-emotional stimuli in amyotrophic lateral sclerosis. These results support the notion of the neurofunctional and neuroanatomical continuum between amyotrophic lateral sclerosis and frontotemporal dementia.

    To evaluate the patterns of cerebral cortical distribution of (11)C-PIB in patients with mild cognitive impairment (MCI). The study included 69 patients (37 male, age range 42-79 years) with MCI, sub-classified as 53 with amnestic-MCI (A-MCI), and 16 with non-amnestic-MCI (NA-MCI). Patients underwent (11)C-PIB PET/CT scan 60min after intravenous injection of the radiotracer. A visual analysis of the images was performed by 2 experienced physicians. (11)C-PIB-positive studies were considered when gray matter uptake was equal to or greater than white matter. According to the regions involved, (11)C-PIB-positive studies were classified into A-pattern (predominant retention in frontal, anterior cingulate, lateral temporal, and basal ganglia) and B-pattern (generalized retention). Thirty-nine of the 69 (56%) patients with MCI showed (11)C-PIB retention. Of the 53 A-MCI patients, 36 (68%) showed (11)C-PIB retention. Eleven out of 36 (30%) positive scans in A-MCI patients showed A-pattern, and 25 out of 36 (70%) patients had a B-pattern. Positive (11)C-PIB was observed in 3 out of 16 (19%) patients with NA-MCI. Regional distribution in these 3 patients showed A-pattern in 1, and B-pattern in 2 patients. Cortical retention of (11)C-PIB was more frequent in A-MCI than in NA-MCI patients, and also B-pattern than A-pattern in the (11)C-PIB positive group.

    In several previous behavioral studies, we have identified a group of amnestic patients that, behaviorally, appear to exhibit severe deficits in recollection with relative preservation of familiarity-based recognition. However, these studies have relied exclusively on behavioral measures, rather than direct measures of physiology. Event-related potentials (ERPs) have been used to identify putative neural correlates of familiarity- and recollection-based recognition memory, but little work has been done to determine the extent to which these ERP correlates are spared in patients with relatively specific memory disorders. ERP studies of recognition in healthy subjects have indicated that recollection and familiarity are related to a parietal old-new effect characterized as a late positive component (LPC) and an earlier mid-frontal old-new effect referred to as an 'FN400', respectively. Here, we sought to determine the extent to which the putative ERP correlates of recollection and familiarity are intact or impaired in these patients. We recorded ERPs in three amnestic patients and six age matched controls while they made item recognition and source recognition judgments. The current patients were able to discriminate between old and new items fairly well, but showed nearly chance-level performance at source recognition. Moreover, whereas control subjects exhibited ERP correlates of memory that have been linked to recollection and familiarity, the patients only exhibited the mid-frontal FN400 ERP effect related to familiarity-based recognition. The results show that recollection can be severely impaired in amnesia even when familiarity-related processing is relatively spared, and they also provide further evidence that ERPs can be used to distinguish between neural correlates of familiarity and recollection.

    Inconsistent results exist regarding the cognitive profile in patients with Parkinson's disease with mild cognitive impairment (PD-MCI). We aimed at providing data on this topic from a large cohort of patients with PD-MCI. Sociodemographic, clinical and neuropsychological baseline data from patients with PD-MCI recruited in the multicentre, prospective, observational DEMPARK/LANDSCAPE study were analysed. 269 patients with PD-MCI (age 67.8±7.4, Unified Parkinson's Disease Rating Scale (UPDRS-III) scores 23.2±11.6) were included. PD-MCI subtypes were 39.4% non-amnestic single domain, 30.5% amnestic multiple domain, 23.4% non-amnestic multiple domain and 6.7% amnestic single domain. Executive functions were most frequently impaired. The most sensitive tests to detect cognitive dysfunctions were the Modified Card Sorting Test, digit span backwards and word list learning direct recall. Multiple stepwise regression analyses showed that global cognition, gender and age, but not education or disease-related parameters predicted PD-MCI subtypes. This study with the so far largest number of prospectively recruited patients with PD-MCI indicates that non-amnestic PD-MCI is more frequent than amnestic PD-MCI; executive dysfunctions are the most typical cognitive symptom in PD-MCI; and age, gender and global cognition predict the PD-MCI subtype. Longitudinal data are needed to test the hypothesis that patients with PD-MCI with specific cognitive profiles have different risks to develop dementia. Published by the BMJ Publishing Group Limited.

    Renal blood flow (RBF) was measured in 9 patients with chronic impaired kidney function using MR velocity mapping and compared to PAH clearance and 99mTc-DTPA scintigraphy. An image plane suitable for flow measurement perpendicular to the renal arteries was chosen from 2-dimensional MR angiography...... by 99mTc-DTPA scintigraphy. A reduction of RBF was found, and there was a significant correlation between PAH clearance multiplied by 1/(1-hematocrit) and RBF determined by MR velocity mapping. Furthermore, a significant correlation between the distribution of renal function and the percent distribution...

    This paper describes the design of a prototype telecare system, which allows to provide home care to patients with mild cognitive impairment and thus ensures their permanence in their usual environment. Telecare is oriented towards people who require constant attention due to conditions of advanced age, illness, physical risk or limited capabilities. Telecare offers these people a greater degree of independence. QFD methodology is used to develop electronic devices intended to monitor the environment and physiological state of the user continuously, providing communication between the telecare system and a monitoring center in order to take the most appropriate actions in any abnormal event.

    Patients with renal failure often experience decreased serum zinc that remains uncorrected after dialysis. A complication of this depletion is taste impairment, which can detrimentally influence diet and nutrition. However, because more than half of all serum zinc is bound to albumin, we hypothesized that normalizing serum zinc to albumin levels may be associated with taste impairment. A total of 65 patients undergoing dialysis but not receiving supplementary zinc and 120 control patients not undergoing dialysis (60 malnourished patients and 60 healthy controls) were tested for their receptiveness to saltiness using various salt concentrations. Patients' total protein and albumin levels were measured, and linear regressions were extrapolated between serum zinc levels and total protein or albumin. Patients undergoing dialysis had significantly lower levels of total serum zinc compared with control patients. However, uncorrected zinc levels were not correlated with taste impairment. Normalizing zinc levels against total protein or albumin resulted in extrapolated equations that revealed a significant correlation with taste impairment. Our data suggest a statistical correlation between zinc and albumin in both healthy subjects and patients undergoing maintenance hemodialysis, or protein-energy malnutrition without hemodialysis, allowing for a quantitative measure for taste impairment.

    To determine if some common screening tests predict scores on detailed, objective diagnostic tests of the vestibular system. Sixty patients with vestibular disorders were compared with 60 asymptomatic controls. Vestibular diagnostic laboratory, tertiary care center. Subjects were screened with head impulse tests, Fukuda stepping tests while walking and marching in place, and tandem walking tests with eyes open and closed. All subjects underwent bithermal caloric tests and Dix-Hallpike maneuvers; patients underwent low-frequency sinusoidal tests of the vestibulo-ocular reflex in darkness and cervical vestibular evoked myogenic potentials. On tandem walking tests, patients differed significantly from controls, but receiver operating characteristic scores were walking but not marching, but receiver operating characteristic values were considerably less than 0.80. On head impulse tests, patients with bithermal caloric weakness (≥20% and 0.80 only for subjects with severe bithermal caloric weakness and were highest, at 0.88, for subjects with severe weakness and age ≥ 60 years. The Fukuda test is a poor screening test because it does not correlate well with objective test findings. Tandem walking is best used for screening older patients for vestibular disorders. Positive findings on a head impulse test are probably consistent with severe peripheral vestibular impairment and may be most useful in older patients. In younger patients with vertigo, negative results on head impulse tests may not be informative. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    The characteristics of hearing impairment (HI) in rheumatoid arthritis (RA) are still poorly understood, and their association with disease activity is based on conflicting information. This study compared HI between RA patients and controls and between active and remission RA groups using multi-frequency audiometry. This study enrolled 88 RA patients and 50 controls. The pure-tone hearing thresholds at 500 to 4000 Hz for air (AC) and bone (BC) conduction were compared between RA and controls as well as between active and remission RA patients using DAS28-CRP scores. The pure-tone hearing thresholds for AC and BC were significantly higher at high frequencies (2000 and 4000 Hz) in the RA group for both ears compared with controls. In addition, the BC threshold at 1000 Hz for the right ear was higher in the RA group than controls. When active and remission RA patients were compared, the thresholds were higher only at 4000 Hz for both ears for AC and BC in patients with active RA. The air-bone gap differed significantly at 2000 and 4000 Hz in both ears. This study demonstrated that patients with RA have a heightened risk of HI, and disease activity increases this risk, particularly at high frequencies. Clinicians who manage RA should be aware of HI and consider performing audiological evaluations in RA patients with active disease in particular.
