    AIM: To investigate the clinical characteristics and prognostic factors of a consecutive series of patients with severe acute pancreatitis (SAP).METHODS: Clinical data of SAP patients admitted to our hospital from January 2003 to January 2004 were retrospectively reviewed. Collected data included the age, gender, etiology,length of hospitalization, APACHE Ⅱ score at admission,local and organ/systemic complications of the patients.RESULTS: Of the 268 acute pancreatitis patients, 94 developed SAP. The mean age of SAP patients was 52 years, the commonest etiology was cholelithiasis (45.7%), the mean length of hospitalization was 70 d, the mean score of APACHE Ⅱ was 7.7. Fifty-four percent of the patients developed necrosis, 25% abscess, 58% organ/systemic failure. A total of 23.4% (22/94) of the SAP patients died. Respiratory failure was the most common organ clysfunction (90.9%) in deceased SAP patients, followed by cardiovascular failure (86.4%),renal failure (50.0%). In the SAP patients, 90.9% (20/22)developed multiple organ/systemic failures. There were significant differences in age, length of hospitalization,APACHE Ⅱ score and incidences of respiratory failure, renal failure, cardiovascular failure and hematological failure between deceased SAP patients and survived SAP patients.By multivariate logistic regression analysis, independent prognostic factors for mortality were respiratory failure,cardiovascular failure and renal failure.CONCLUSION: SAP patients are characterized by advanced age, high APACHE Ⅱ score, organ failure and their death is mainly due to multiple organ/systemic failures. In patients with SAP, respiratory, cardiovascular and renal failures can predict the fatal outcome and more attention should be paid to their clinical evaluation.

    The present study had three objectives: (a) to characterize the functional capacity of patients with PD, (b) to assess the relationship between the physical fitness components of functional capacity with clinical characteristics and disease severity, and (c) to compare the physical fitness components of functional capacity with clinical characteristics according to disease severity. The study included 54 patients with idiopathic PD who were distributed into two groups according to PD severity: unilateral group (n=35); and bilateral group (n=19). All patients underwent psychiatric assessment by means of the Hoehn and Yahr (HY) staging of PD, the Unified Parkinson's Disease Rating Scale (UPDRS), the Hospital Anxiety and Depression Scale (HADS-A and HADS-D, respectively), and The Mini-Mental State Examination (MMSE). The physical fitness components of functional capacity were evaluated over a 2-day period, using recommendations by the American Alliance for Health, Physical Education, Recreation and Dance, and the Berg Balance Scale (BBS). Pearson correlation coefficients and multiple regressions were calculated to test the correlation between functional capacity and clinical characteristics, and to predict clinical scores from physical performance, respectively. Clinical variables and physical component data were compared between groups using analysis of variance to determine the effects of disease severity. Patients with advanced disease showed low levels of functional capacity. Interestingly, patients with good functional capacity in one of the physical fitness components also showed good capacities in the other components. Disease severity is a major factor affecting functional capacity and clinical characteristics. Medical providers should take disease severity into consideration when prescribing physical activity for PD patients, since the relationship between functional capacity and clinical characteristics is dependent on disease severity.

    Full Text Available Abstract Background Non-typhoidal Salmonella (NTS is increasingly recognized as an important pathogen associated with bacteraemia especially in immunosuppressed patients. However, there is limited data specifically describing the clinical characteristics and outcome amongst the immunosuppressed patients. Methods A total of 56,707 blood culture samples and 5,450 stool samples were received by the microbiology laboratory at a tertiary referral hospital in Malaysia, during a 4-year study period. Out of these samples, 55 non-duplicate NTS isolates were identified from blood and 121 from stool. A retrospective analysis of the 55 patients with NTS bacteraemia was then conducted to determine the predominant NTS serovars causing bacteraemia and its' blood invasive potential, epidemiological data, clinical characteristics and antimicrobial susceptibility. Patients were then grouped as immunosuppressed and non-immunosuppressed to determine the association of severe immunosuppression on clinical features. Data was analyzed using the Statistical Package for Social Sciences (SPSS version 15.0 using the non-parametric Mann-Whitney test, Fisher's exact test or Chi-squared test. The odds ratio (OR and its 95% confidence intervals (CI were calculated. The P-value Results Out of 55 NTS bacteraemia cases identified, 81.8% (45/55 were community-acquired. Salmonella enterica serovar Enteritidis had the highest blood invasiveness. An extra-intestinal focus of infection was noted in 30.9% (17/55 of the patients, most commonly involving the lungs and soft tissue. 90.9% (50/55 of the patients had an underlying disease and 65.5% (36/55 of the patients had severe clinical immunosuppressive condition with malignancy and HIV being the most common. Immunosuppressed patients had higher mortality (P = 0.04, presented more commonly with primary bacteraemia (P = 0.023, leukopenia (P = 0.001 and opportunistic infections (P = 0.01.

    Full Text Available AbstractObjective: To describe the clinical characteristics, lung function, radiological findings, and the inflammatory cell profile in induced sputum in children and adolescents with severe therapy-resistant asthma (STRA treated at a referral center in southern Brazil.Methods: We retrospectively analyzed children and adolescents (3-18 years of age with uncontrolled STRA treated with high-dose inhaled corticosteroids and long-acting β2 agonists. We prospectively collected data on disease control, lung function, skin test reactivity to allergens, the inflammatory cell profile in induced sputum, chest CT findings, and esophageal pH monitoring results.Results: We analyzed 21 patients (mean age, 9.2 ± 2.98 years. Of those, 18 (86% were atopic. Most had uncontrolled asthma and near-normal baseline lung function. In 4 and 7, induced sputum was found to be eosinophilic and neutrophilic, respectively; the inflammatory cell profile in induced sputum having changed in 67% of those in whom induced sputum analysis was repeated. Of the 8 patients receiving treatment with omalizumab (an anti-IgE antibody, 7 (87.5% showed significant improvement in quality of life, as well as significant reductions in the numbers of exacerbations and hospitalizations.Conclusions: Children with STRA present with near-normal lung function and a variable airway inflammatory pattern during clinical follow-up, showing a significant clinical response to omalizumab. In children, STRA differs from that seen in adults, further studies being required in order to gain a better understanding of the disease mechanisms.

    Introduction Severe right ventricular hypertrophy (SRVH) is a rare phenotype in hypertrophic cardiomyopathy (HCM) for which limited information is available. This study was undertaken to investigate the clinical, prognostic and genetic characteristics of HCM patients with SRVH. Methods HCM with SRVH was defined as HCM with a maximum right ventricular wall thickness ≥10 mm. Whole-genome sequencing (WGS) was performed in HCM patients with SRVH. Multivariate Cox proportional hazards regression models were used to identify risk factors for cardiac death and events in HCM with SRVH. Patients with apical hypertrophic cardiomyopathy (ApHCM) were selected as a comparison group. The clinical features and outcomes of 34 HCM patients with SRVH and 273 ApHCM patients were compared. Results Compared with the ApHCM group, the HCM with SRVH group included younger patients and a higher proportion of female patients and also displayed higher cardiovascular morbidity and mortality. The multivariate Cox proportional hazards regression models identified 2 independent predictors of cardiovascular death in HCM patients with SRVH, a New York Heart Association class ≥III (hazard ratio [HR] = 8.7, 95% confidence interval (CI): 1.43-52.87, p = 0.019) and an age at the time of HCM diagnosis ≤18 (HR = 5.5, 95% CI: 1.24-28.36, p = 0.026). Among the 11 HCM patients with SRVH who underwent WGS, 10 (90.9%) were identified as carriers of at least one specific sarcomere gene mutation. MYH7 and TTN mutations were the most common sarcomere mutations noted in this study. Two or more HCM-related gene mutations were observed in 9 (82%) patients, and mutations in either other cardiomyopathy-related genes or ion-channel disease-related genes were found in 8 (73%) patients. Conclusions HCM patients with SRVH were characterized by poor clinical outcomes and the presentation of multiple gene mutations. PMID:28323875

    Full Text Available The peculiarities of clinical signs, immune and interferon status in 180 patients with laboratory confirmed infection of varying severity, caused by herpes simplex virus (VSHI have been studied. It was determined that frequency of bacterial infections is increased in patients with more severe clinical forms of VSHI. In patients with mild course furunculosis was more often detected than in other groups. In patients with moderate course of VSHI vaginal candidiasis was more common. In patients with severe VSHI course the combination of labial and genital herpes as well as infection caused by the human papilloma virus were more prevalent. In case of severe infection occurred an increased frequency of dysbiosis, fatigue, low grade temperature, iron deficiency anemia and malignancies. The highest frequency of allergic reactions is observed in patients with moderate course of VSHI. The autoimmune syndrome manifestations were not depend on the severity of VSHI. The degree of reduction of cell immunity and disorders in the system of interferon were closely related to severity of VSHI course.

    Severe fever with thrombocytopenia syndrome (SFTS) was firstly discovered in China in 2010, followed by several reports from many other countries worldwide. SFTS virus (SFTSV) has been identified as the causative agent of the disease and has been recognized as a public health threat. This novel Bunyavirus belongs to the Phlebovirus genus in the family Bunyaviridae. This review also describes the different aspects of virology, pathogenesis, epidemiology, and clinical symptoms on the basis of the published article surveillance data and phylogenetic analyses of viral sequences of large, medium, and small segments retrieved from database using mega 5.05, simplot 3.5.1, network 4.611, and epi information system 3.5.3 software. SFTS presents with fever, thrombocytopenia, leukocytopenia, and considerable changes in several serum biomarkers. The disease has 10~15% mortality rate, commonly because of multiorgan dysfunction. SFTSV is mainly reported in the rural areas of Central and North-Eastern China, with seasonal occurrence from May to September, mainly targeting those of ≥50 years of age. A wide range of domesticated animals, including sheep, goats, cattle, pigs, dogs, and chickens have been proven seropositive for SFTSV. Ticks, especially Haemaphysalis longicornis, are suspected to be the potential vector, which have a broad animal host range in the world. More studies are needed to elucidate the vector-animal-human ecological cycle, the pathogenic mechanisms in high level animal models and vaccine development.

    Background: To investigate the clinical characteristics and analyze risk factors for severe respiratory syncytial virus (RSV) infection in hospitalized infants with acute lower respiratory tract infections (ALRIs). Methods: A retrospective review of the medical records of infants with RSV-associated ALRIs between March 1st, 2011 and February 29th, 2012 was conducted. Subjects were followed up over the phone or by outpatient visit six and twelve months after discharge. Results: Among 913 RSV-associated ALRIs infants, 288 (31.5%) had severe infections, which accounted for 4.2% of hospitalized children. The hospital RSV mortality rate was 1.0%. The proportions of cases with tachypnea, apnea, cyanosis, and fine rales were significantly higher in the severe ALRIs group (all P Conclusions: Younger age, low birth weight and underlying disease are associated with severe RSVassociated ALRIs. Furthermore, severe RSV infections may be associated with a higher frequency of subsequent bronchitis, pneumonia and re-hospitalization in the following year.

    AIM: To study clinical characteristics and management of patients with early severe acute pancreatitis (ESAP).METHODS: Data of 297 patients with severe acute pancreatitis (SAP) admitted to our hospital within 72 h after onset of symptoms from January 1991 to June 2003 were reviewed for the occurrence and development of early severe acute pancreatitis (ESAP). ESAP was defined as presence of organ dysfunction within 72 h after onset of symptoms. Sixtynine patients had ESAP, 228 patients without organ dysfunction within 72 h after onset of symptoms had SAR The clinical characteristics, incidence of organ dysfunction during hospitalization and prognosis between ESAP and SAP were compared.RESULTS: Impairment degree of pancreas (Balthazar CT class) in ESAP was more serious than that in SAP (5.31±0.68 vs 3.68±0.29, P<0.01). ESAP had a higher mortality than SAP (43.4% vs 2.6%, P<0.01), and a higher incidence of hypoxemia (85.5% vs 25%, P<0.01), pancreas infection (15.9% vs7.5% , P<0.05), abdominal compartment syndrome (ACS) (78.3% vs 23.2%, P<0.01) and multiple organ dysfunction syndrome (MODS)(78.3% vs 10.1%, P<0.01). In multiple logistic regression analysis, the main predisposing factors to ESAP were higher APACHE Ⅱ score, Balthazar CT class, MODS and hypoxemia.CONCLUSION: ESAP is characterised by MODS, severe pathological changes of pancreas, early hypoxemia and abdominal compartment syndrome. Given the poor prognosis of ESAP, these patients should be treated in specialized intensive care units with special measures such as close supervision, fluid resuscitation, improvement of hypoxemia, reduction of pancreatic secretion, elimination of inflammatory mediators, prevention and treatment of pancreatic infections.

    Epidemiology and clinical characteristics of invasive Group A streptococcal infections (IGASI) are highly variable. Long-term studies are needed to understand the interplay between epidemiology and virulence. In a population-based study of IGASI in Iceland from 1975 to 2012, 288 cases were identified by positive cultures from normally sterile body sites. Charts were reviewed retrospectively and emm-types of viable Streptococcus pyogenes isolates (n=226) determined. Comparing the first and last decade of the study period, IGASI incidence increased from 1.09 to 3.96 cases per 100,000 inhabitants per year. The most common were emm types 1 (25%), 28 (11%) and 89 (11%); emm1 strains were most likely to cause severe infections. Infections in adults were significantly more likely to be severe during the seasonal peak from January to April (risk ratio: 2.36, 95% confidence interval: 1.34–4.15). Significant seasonal variability in severity was noted among patients with diagnosis of sepsis, respiratory infection and cellulitis, with 38% of severe infections in January to April compared with 16% in other months (p<0.01). A seasonal increase in severity of IGASI suggested that generalised seasonal increase in host susceptibility, rather than introduction of more virulent strains may play a role in the pathogenesis of these potentially fatal infections.

    2016-01-01

    Background We investigated the trends in the clinical characteristics and prescriptions of type 2 diabetic patients with severe hypoglycemia because the prescription rate of antidiabetic agents has significantly changed recently. Methods A total of 193 patients with type 2 diabetes with severe hypoglycemia induced by antidiabetic agents between 2008 and 2013 were divided into three groups based on the period of visit: 2008 - 2009, 2010 - 2011 and 2012 - 2013. Results While the proportion of patients with severe hypoglycemia using insulin (from 55% to 74%), biguanides (from 6% to 20%), glinides, and dipeptidyl peptidase-4 inhibitors significantly increased, those using sulfonylureas (from 45% to 20%) significantly decreased. Errors of drug use significantly increased as a trigger of hypoglycemia in recent years. The number of antidiabetic agents (from 1.9 ± 0.6 to 2.3 ± 0.7), non-diabetic agents (from 2.3 ± 2.4 to 4.3 ± 3.3), and total drugs prescribed were significantly higher in recent years among patients receiving insulin therapy. Conclusions Polypharmacy especially in patients receiving insulin therapy and errors of drug use have increased in type 2 diabetic patients with severe hypoglycemia in recent years. Intensive education in the usage rule of drugs is considered to be important in order to prevent severe hypoglycemia. PMID:27635175

    Full Text Available The aim of the study was to compare the clinical and anthropometric characteristics of patients with COPD, which differ in the degree of airways obstruction and belong to groups A, B, C, D in accordance with GOLD, 2011 classification. A total of 112 ambulatory COPD patients in remission made the study sample. Anthropometric data, body mass index, medical history, dyspnea by mMRC scale, and spirometry was performed for all patients. There was confirmed that outpatients with COPD is a heterogeneous group, in which the majority are those with moderate (48.22 % and severe (30.36 %, airway obstruction. Despite the vast majority of men among outpatients, the percentage of women among patients with mild to moderate obstruction (22.58±5.31 % was significantly higher (p=0.002 as compared with those with severe or very severe limitation of airflow (6.00±3.36 %. Patients with severe and very severe obstruction were of significantly older age (p = 0.024. At the same time, the distribution of patients according to the GOLD, 2011 classification, demonstrate that all groups did not differ on any of the anthropometric indicators, including gender and age (p > 0.050. Distribution of patients by groups with different risk for future exacerbations is not a mirror image of gradation in accordance with the degree of airway obstruction. Every second (50.00±4.43 % of cases patient is included in group C and every tenth (10.20±4.32 % belongs to the group D not due to degree of bronchial obstruction, but due to the number of exa­cerbations in the past year. Therefore, in future studies it is advisable to use both principles of patients’ classification.

    Full Text Available Background: The last couple of decades has seen an increasing interest in molar-incisor hypomineralization (MIH. Although the reported prevalence of MIH ranges from 2.4% to 40.2% worldwide, very little data is available from India. Objective: To assess the prevalence, clinical characteristics, distribution, severity and association with caries of MIH defects in children aged 8-13 years of Udaipur, Rajasthan. Study design: This cross-sectional descriptive study consisted of 1173 children aged 8-13 years selected by random sampling procedure. The European Academy of Pediatric Dentistry criteria were followed for MIH diagnosis. The presence of dental caries and treatment need for MIH-affected teeth were recorded as per the WHO criteria. Results: The prevalence of MIH in the children examined was 9.46%. Severity of the defects increased with the age of the children. Involvement of incisors increased when more First permanent molars (FPMs were affected. An average of 3.65 teeth was involved per MIH-affected individual. Significantly larger numbers of mandibular FPMs and maxillary central incisors were diagnosed with MIH. The association of dental caries was significantly higher with MIH-affected FPMs. Primary molars and permanent canines and premolars were also showed MIH like lesions in some of the MIH-affected children. Conclusion: MIH was observed in about 10% of the children examined. MIH-affected FPMs appear to be more vulnerable to early caries and subsequent pulp involvement with need for extensive dental treatment.

    Full Text Available Background: preeclampsia is a hypertensive disorder of pregnancy and a major cause of perinatal and maternal morbidity and mortality. Objective: to identify maternal and therapeutic factors as well as damage associated with severe preeclampsia in pregnant women. Method: a case series study was conducted in 69 patients diagnosed with severe preeclampsia treated at the Dr. Gustavo Aldereguía Lima University General Hospital from January 1, 2012 through December 31, 2013. They were divided into two groups according to presence of severe preeclampsia with and without aggravating factors. The variables analyzed were related to maternal characteristics, characteristics of medical care and fetal and neonatal characteristics. A questionnaire based on the data obtained from medical records was applied in line with the International Classification of Diseases, Tenth Revision. Comparisons between groups were performed using a chi-square statistic, considering a P<0.05 statically significant. Results: frequency of severe preeclampsia was 0.8 per 100 deliveries. The highest frequency occurred in the age range of 31-35 years. Eclampsia was observed in 0.91 per 1000 deliveries. Maternal damage amounted to 30.4%. Magnesium sulfate prophylaxis was used in 89% of cases. Eclampsia frequency when not used was 50%, while it was only 6.4% when this therapy was applied. Caesarean section was performed in 85.5% of patients. Neonatal damage was 52.3%. The late fetal death rate was 4.6 per 100 live births. Among the intergroup differences, significant dissimilarities were observed in neonatal damage. Conclusion: high association of intrauterine growth restriction with induced prematurity is evident as well as the high rate of first-time Caesarean sections and significant maternal, fetal and neonatal damage. The use of magnesium sulfate shows good results in the prophylaxis of eclampsia.

    Ninety-nine children admitted to the Instituto Materno Infantil de Pernambuco with severe malnutrition from May 1999 to May 2000 were investigated in a cross-sectional study focusing on key epidemiological and clinical variables. The majority of the children (88.9%) were less than 6 months of age, 42.4% had a history of low birth weight, and 36.4% were premature. Some 19.2% had never been breastfed, and 49.5% had been breastfed for less than 2 months. Some 15.2% of the mothers were illiterate. Most of the families (86.1%) had incomes less than twice the minimum wage (approximately US$150/month), and 51.5% had migrated from rural areas. Only 26.3% of the homes had running water, and 40.4% lacked sewage disposal facilities. Diarrhea was the reason for hospital admission in 55.6% of the cases. Hospital mortality was 34.3% in this group.

    Severe combined immunodeficiency (SCID), a rare type of genetic associated immune disorder, is poorly characterized in mainland China. We retrospectively reviewed 44 patients with SCID who received treatment from 2004 to 2011 in Shanghai, China, and herein summarize their clinical manifestations and immunological and preliminary genetic features. The male-to-female ratio was 10:1. Twenty five patients presented with X-SCID symptoms. Only one patient was diagnosed before the onset of symptoms due to positive family history. The mean time of delay in the diagnosis of X-SCID was 2.69 months (range, 0.5-8.67). Thirty-seven of the 44 patients died by the end of 2011 with the mean age of death being 7.87 months (range, 1.33-31). Six patients received hematopoietic stem cell transplantation (HSCT); only one of them survived, who was transplanted twice. The time between onset and death was shorter in the HSCT-treated group compared with the untreated group (2.87 ± 1.28 and 3.34 ± 0.59 months, respectively), probably due to active infections during transplantation. Bacillus Calmette-Guérin (BCG) complications occurred in 14 of the 34 patients who received BCG vaccination. Transfusion-induced graft-versus-host disease occurred in 5 patients. Total 20 mutations in interleukin-2 receptor subunit gamma (IL2RG) were identified in 22 patients, including 11 novel mutations. Most patients were misdiagnosed before referred to our SCID Center. Therefore, establishing more diagnostic centers dedicated to the care of PID and accessible by primary immunodeficiency patients will facilitate early, correct diagnosis and better care of SCID in China.

    Since the drop in the bed capacity of civil psychiatric hospitals, an increase in the bed capacity of forensic psychiatric care and prison units has been reported in the United States and Europe. However, in Canada, a decrease in the number of people with severe mental illness (SMI) during the last two decades in penitentiaries has been reported. At the same time, an increase in individuals found not criminally responsible on account of mental disorder (NCRMD) was observed in forensic hospitals. The aim of this study is to compare incarcerated severely mentally ill (I-SMI) individuals with forensic-hospitalized SMI individuals in terms of their clinical profiles and service use in the province of Quebec (Canada). A case-control study design was selected using a sample of 44 I-SMI individuals and 59 forensic-hospitalized SMI individuals. Important findings include the following: I-SMI persons had less schooling; they more often reported suicide attempts and violent and non-violent crimes; and they had a higher level of comorbidity involving Cluster B personality disorders and substance-use disorders. Forensic-hospitalized SMI persons were more likely to have been receiving psychiatric follow-up before hospitalization. The final logistic regression model showed that lifetime suicide attempts, non-violent crimes, and psychopathic traits were higher among I-SMI individuals than among forensic-hospitalized SMI individuals. In contrast, receiving regular psychiatric follow-up was associated with forensic-hospitalized SMI individuals. Differences in psychopathological characteristics and the use of mental health services were found for I-SMI persons. More research is needed to determine which new initiatives might be efficacious in addressing the mental health needs of I-SMI individuals.

Early onset severe preeclampsia (ES-PE) is a specific subtype of hypertensive disorders complicating pregnancy. It is characterized by high incidence rates of maternal complications and high perinatal mortality, and early onset and severe complications, so it threatens safty of the pregnant women and the perineonate severely. Early prediction and identification of complications are helpful to monitor severity of the disease and guide clinical treatment. But no confirmed and more definite predicting method of ES-PE before labor is found, and preciously predicting the risk of developing the disease remains a challenge. The women who had a previous history of ES-PE had an increased replase risk of the disease and increased incidence rates of adverse pregnancy complications and outcomes in their subsequent pregnancies. So expectant management which improves perinatal outcomes is very important in clinical treatment. In this article, we reviewed progress in research on ES-PE.

    Full Text Available Background: Parthenium dermatitis is the most common type of airborne contact dermatitis in India. It is a chronic disease of a remitting and relapsing course with significant morbidity and distress, but there is no scoring system to assess its severity. Aim: To design a scoring system for the assessment of clinical severity of disease in Parthenium dermatitis and to use this scoring system in various studies to determine its sensitivity, specificity, and reproducibility. Methods and Results: In our first few studies on Parthenium dermatitis, we designed and used a basic clinical severity scoring system based on itching, morphology of the lesions, and areas involved. However, in subsequent studies, we modified it to the present scoring system as Parthenium dermatitis severity score (PDSS. Our studies showed the high sensitivity of PDSS in characterization of the disease severity at the given point of time, as well as to determine the efficacy of a prescribed treatment modality which was reliable and reproducible. Conclusion: Thus, PDSS may be used by clinicians for appropriate scoring of the clinical severity of Parthenium dermatitis and in monitoring the disease response to therapy.

    Full Text Available The first symptoms of malaria, common to all the different malaria species, are nonspecific and mimic a flu-like syndrome. Although fever represents the cardinal feature, clinical findings in malaria are extremely diverse and may range in severity from mild headache to serious complications leading to death, particularly in falciparum malaria. As the progression to these complications can be rapid, any malaria patient must be assessed and treated rapidly, and frequent observations are needed to look for early signs of systemic complications. In fact, severe malaria is a life threatening but treatable disease.  The protean and nonspecific clinical findings occurring in malaria (fever, malaise, headache, myalgias, jaundice and sometimes gastrointestinal symptoms of nausea, vomiting and diarrhoea may lead physicians who see malaria infrequently to a wrong diagnosis, such as influenza (particularly during the seasonal epidemic flu, dengue, gastroenteritis, typhoid fever, viral hepatitis, encephalitis. Physicians should be aware that malaria is not a clinical diagnosis but must be diagnosed, or excluded, by performing microscopic examination of blood films. Prompt diagnosis and appropriate treatment are then crucial to prevent morbidity and fatal outcomes. Although Plasmodium falciparum malaria is the major cause of severe malaria and death, increasing evidence has recently emerged that Plasmodium vivax and Plasmodium knowlesi can also be severe and even fatal.

    The radiologist plays a crucial role in identifying and narrowing the differential diagnosis of intracranial infections. A thorough understanding of the intracranial compartment anatomy and characteristic imaging findings of specific pathogens, as well incorporation of the clinical information, is essential to establish correct diagnosis. Specific types of infections have certain propensities for different anatomical regions within the brain. In addition, the imaging findings must be placed in the context of the clinical setting, particularly in immunocompromised and human immunodeficiency virus (HIV)-positive patients. This paper describes and depicts infections within the different compartments of the brain. Pathology-proven infectious cases are presented in both immunocompetent and immunocompromised patients, with a discussion of the characteristic findings of each pathogen. Magnetic resonance spectroscopy (MRS) characteristics for several infections are also discussed.

    2007-01-01

    Caroli's syndrome is characterized by multiple segmental cystic or saccular dilatations of intrahepatic bile ducts associated with congenital hepatic fibrosis. The clinical features of this syndrome reflect both the characteristics of congenital hepatic fibrosis such as portal hypertension and that of Caroli's disease named as recurrent cholangitis and cholelithiasis. The diagnosis depends on both histology and imaging methods which can show the communication between the sacculi and the bile ducts. Treatment consists of symptomatic treatment of cholangitis attacks by antibiotics, some endoscopic,radiological and surgical drainage procedures and surgery. Liver transplantation seems the ultimate treatment for this disease. Prognosis is fairly good unless recurrent cholangitis and renal failure develops.

  2. Severe acute pancreatitis: Clinical course and management

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Severe acute pancreatitis (SAP) develops in about 25% of patients with acute pancreatitis (AP). Severity of AP is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis pathomorphologically.Risk factors determining independently the outcome of SAP are early multi-organ failure, infection of necrosis and extended necrosis (> 50%). Up to one third of patients with necrotizing pancreatitis develop in the late course infection of necroses. Morbidity of SAP is biphasic, in the first week strongly related to early and persistence of organ or multi-organ dysfunction. Clinical sepsis caused by infected necrosis leading to multi-organ failure syndrome (MOFS) occurs in the later course after the first week. To predict sepsis, MOFS or deaths in the first 48-72 h, the highest predictive accuracy has been objectified for procalcitonin and IL-8; the SepsisRelated Organ Failure Assessment (SOFA)-score predicts the outcome in the first 48 h, and provides a daily assessment of treatment response with a high positive predictive value. Contrast-enhanced CT provides the highest diagnostic accuracy for necrotizing pancreatitis when performed after the first week of disease. Patients who suffer early organ dysfunctions or at risk of developing a severe disease require early intensive care treatment. Early vigorous intravenous fluid replacement is of foremost importance. The goal is to decrease the hematocrit or restore normal cardiocirculatory functions.Antibiotic prophylaxis has not been shown as an effective preventive treatment. Early enteral feeding is based on a high level of evidence, resulting in a reduction of local and systemic infection. Patients suffering infected necrosis causing clinical sepsis, pancreatic abscess or surgical acute abdomen are candidates for early intervention. Hospital mortality of SAP after interventional or surgical debridement has decreased in high volume centers to below 20%.

    In order to clarify the characteristics of epilepsy in patients with severe mentally retarded (SMR) subjects, we analyzed 52 SMR subjects with epilepsy from the institute for SMR subjects at Kikuchi National Hospital, Kumamoto, Japan. A total of 61.5% patients had uncontrolled seizures which were resistant to treatment. The most common combinations of seizure types in those not responding to conventional anticonvulsants were generalized tonic-clonic seizures (GTCS) with tonic seizure and GTCS with atypical absence. Their clinical features were characterized by spastic paralysis associated with a slower background electroencephalogram and abnormal computed tomography scans of the head, suggesting the involvement of cortical damage. These findings suggest that a large proportion of epilepsy in SMR subjects does not respond to treatment and that the severity of organic brain damage may therefore affect the natural course of epilepsy in such patients.

    2005-09-01

    The erythrocytic cycle of Plasmodium falciparum presents a particularity in relation to other Plasmodium species that infect man. Mature trophozoites and schizonts are sequestered from the peripheral circulation due to adhesion of infected erythrocytes to host endothelial cells. Modifications in the surface of infected erythrocytes, termed knobs, seem to facilitate adhesion to endothelium and other erythrocytes. Adhesion provides better maturation in the microaerophilic venous atmosphere and allows the parasite to escape clearance by the spleen which recognizes the erythrocytes loss of deformability. Adhesion to the endothelium, or cytoadherence, has an important role in the pathogenicity of the disease, causing occlusion of small vessels and contributing to failure of many organs. Cytoadherence can also describe adhesion of infected erythrocytes to uninfected erythrocytes, a phenomenon widely known as rosetting. Clinical aspects of severe malaria, as well as the host receptors and parasite ligands involved in cytoadherence and rosetting, are reviewed here. The erythrocyte membrane protein 1 of P. falciparum (PfEMP1) appears to be the principal adhesive ligand of infected erythrocytes and will be discussed in more detail. Understanding the role of host receptors and parasite ligands in the development of different clinical syndromes is urgently needed to identify vaccination targets in order to decrease the mortality rates of this disease.

    Full Text Available The erythrocytic cycle of Plasmodium falciparum presents a particularity in relation to other Plasmodium species that infect man. Mature trophozoites and schizonts are sequestered from the peripheral circulation due to adhesion of infected erythrocytes to host endothelial cells. Modifications in the surface of infected erythrocytes, termed knobs, seem to facilitate adhesion to endothelium and other erythrocytes. Adhesion provides better maturation in the microaerophilic venous atmosphere and allows the parasite to escape clearance by the spleen which recognizes the erythrocytes loss of deformability. Adhesion to the endothelium, or cytoadherence, has an important role in the pathogenicity of the disease, causing occlusion of small vessels and contributing to failure of many organs. Cytoadherence can also describe adhesion of infected erythrocytes to uninfected erythrocytes, a phenomenon widely known as rosetting. Clinical aspects of severe malaria, as well as the host receptors and parasite ligands involved in cytoadherence and rosetting, are reviewed here. The erythrocyte membrane protein 1 of P. falciparum (PfEMP1 appears to be the principal adhesive ligand of infected erythrocytes and will be discussed in more detail. Understanding the role of host receptors and parasite ligands in the development of different clinical syndromes is urgently needed to identify vaccination targets in order to decrease the mortality rates of this disease.O ciclo eritrocítico do Plasmodium falciparum apresenta uma particularidade em relação às outras espécies de Plasmodium que infectam o homem. Trofozoítas maduros e esquizontes são seqüestrados da circulação periférica devido à adesão de eritrócitos infectados às células endoteliais. Modificações na superfície dos eritrócitos infectados, denominadas "knobs", permitem adesão ao endotélio e a outros eritrócitos.

    The incidence of cutaneous melanoma has increased significantly worldwide over the last several decades. The aim of this study is to determine clinical and morphology characteristics of primary melanoma, since some of them are important prognostic factors. This retrospective study included 172 patients. The data were collected by the Consulting team for malignant skin tumors in the Banja Luka Clinical Centre from 2009 to 2011. We did not use dermoscopy as a diagnostic tool in our investigation. We determined that melanoma occurs equally commonly in both sexes, in women in the sixth decade and the seventh in men. The most common sub-type was nodular melanoma (59.5%, P<0.05), followed by superficial spreading (27.8%) and acral lentiginous melanoma (11.4%). The most common localization was on the back in men (34.3%) and on the legs in women (P<0.05). More than half of our patients (55.8%) had melanoma thickness from 1.0 to 4.0 mm, and 38% had a melanoma thicker than 4.0 mm. The average Breslow thickness is 4.6 mm. More women than men had melanoma thicker than 4 mm (P<0.05). Spread of the primary tumor localization was found in 31.4% of patients, more frequently in men than in women (P<0.05). In most cases it was abstraction of lymph nodes (P<0.05). The average thickness of the melanoma in our patients is much higher than the average in the world and the countries of Europe. The results of this study indicate a need for better unique regional registry in this part of Bosnia and Herzegovina and improvement of preventive measures in the early diagnosis of melanoma.

    Objective To investigate the clinical characters of severe acute stroke complicated with upper gastrointestinal bleeding. Methods The clinical data of 180 patients with severe acute hemorrhagic or cerebral infarction were retrospectively analyzed. Results The incidence of severe acute stroke complicated with upper gastrointestinal bleeding was 28.3% (51/180). The upper gastrointestinal bleeding often occurred 2 to 7 days after acute stroke. The incidence of upper gastrointestinal bleeding in the patients with severe acute cerebral infarction was 31.3%, a little higher than that of the patients with severe cerebral hemorrhage (27.3%), but not significantly. Multivariate logistic regression analysis showed that senility, low GCS score and previous history of aspirin use were the important risk factors of upper gastrointestinal bleeding. The vast majority of patients with severe acute stroke complicated with upper gastrointestinal hemorrhage were treated with fasting and proton pump inhibitor. The mortality within 90 days of the patients complicated with upper gastrointestinal bleeding was 62.7% (32/52), significantly higher than that of the patients not complicated with upper gastrointestinal bleeding [32 45.7% (59/129), P<0.05]. Conclusion The patients with severe acute stroke are susceptible to upper gastrointestinal bleeding. The prognosis of acute stroke complicated with upper gastrointestinal bleeding is poor.%目的 探讨急性重症脑卒中患者并发上消化道出血的临床特点.方法 对180例符合入选标准 的急性重症脑出血或脑梗死患者的临床资料进行回顾性分析.结果 急性重症脑卒中患者上消化道出血 发生率为28.3%,上消化道出血多发生于卒中2~7 d之内.急性重症脑梗死患者上消化道出血的发生率 为31.3%,略高于重症脑出血患者(27.3%),但二者比较无显著差异.高龄、入院GCS评分低、发病前服用 小剂量阿司匹林是重症脑卒中患者并发上消化道

    Impacts of a drought are generally dependent on the severity of the hydrological drought event, which can be expressed by streamflow drought duration or deficit volume. For prediction and the selection of drought sensitive regions, it is crucial to know how streamflow drought severity relates to climate and catchment characteristics. In this study we investigated controls on drought severity based on a comprehensive Austrian dataset consisting of 44 catchments with long time series of hydrometeorological data (on average around 50 year) and information on a large number of physiographic catchment characteristics. Drought analysis was performed with the variable threshold level method and various statistical tools were applied, i.e. bivariate correlation analysis, heatmaps, linear models based on multiple regression, varying slope models, and automatic stepwise regression. Results indicate that streamflow drought duration is primarily controlled by storage, quantified by the Base Flow Index or by a combination of catchment characteristics related to catchment storage and release, e.g. geology and land use. Additionally, the duration of dry spells in precipitation is important for streamflow drought duration. Hydrological drought deficit, however, is governed by average catchment wetness (represented by mean annual precipitation) and elevation (reflecting seasonal storage in the snow pack and glaciers). Our conclusion is that both drought duration and deficit are governed by a combination of climate and catchment control, but not in a similar way. Besides meteorological forcing, storage is important; storage in soils, aquifers, lakes, etc. influences drought duration and seasonal storage in snow and glaciers influences drought deficit. Consequently, the spatial variation of hydrological drought severity is highly dependent on terrestrial hydrological processes.

  6. Herbal Hepatotoxicity: Clinical Characteristics and Listing Compilation.

    2016-04-27

    Herb induced liver injury (HILI) and drug induced liver injury (DILI) share the common characteristic of chemical compounds as their causative agents, which were either produced by the plant or synthetic processes. Both, natural and synthetic chemicals are foreign products to the body and need metabolic degradation to be eliminated. During this process, hepatotoxic metabolites may be generated causing liver injury in susceptible patients. There is uncertainty, whether risk factors such as high lipophilicity or high daily and cumulative doses play a pathogenetic role for HILI, as these are under discussion for DILI. It is also often unclear, whether a HILI case has an idiosyncratic or an intrinsic background. Treatment with herbs of Western medicine or traditional Chinese medicine (TCM) rarely causes elevated liver tests (LT). However, HILI can develop to acute liver failure requiring liver transplantation in single cases. HILI is a diagnosis of exclusion, because clinical features of HILI are not specific as they are also found in many other liver diseases unrelated to herbal use. In strikingly increased liver tests signifying severe liver injury, herbal use has to be stopped. To establish HILI as the cause of liver damage, RUCAM (Roussel Uclaf Causality Assessment Method) is a useful tool. Diagnostic problems may emerge when alternative causes were not carefully excluded and the correct therapy is withheld. Future strategies should focus on RUCAM based causality assessment in suspected HILI cases and more regulatory efforts to provide all herbal medicines and herbal dietary supplements used as medicine with strict regulatory surveillance, considering them as herbal drugs and ascertaining an appropriate risk benefit balance.

    Knowledge of illness perception may aid the identification of groups of patients with a higher risk of coping poorly with the demands of their illness. This study aims to investigate associations between illness perception, clinical characteristics, patient knowledge, quality of life and subjective health in persons with psoriasis. The present study was based on cross-sectional data from patients awaiting climate therapy in Gran Canaria. We included 254 eligible patients (74%) who completed a questionnaire including the revised Illness Perception Questionnaire, the Psoriasis Knowledge Questionnaire, and the Dermatological Life Quality Index. Disease severity was measured using the Psoriasis Area and Severity Index. Several statistically significant associations between clinical characteristics, knowledge and various illness perception dimensions were found. Illness perception was also significantly related to disease-specific quality of life and subjective health. These findings contradict previous findings, which suggested that objective disease factors are not relevant to illness perception in psoriasis.

    Full Text Available Currently, several assays can confirm acute dengue infection at the point-of-care. However, none of these assays can predict the severity of the disease symptoms. A prognosis test that predicts the likelihood of a dengue patient to develop a severe form of the disease could permit more efficient patient triage and treatment. We hypothesise that mRNA expression of apoptosis and innate immune response-related genes will be differentially regulated during the early stages of dengue and might predict the clinical outcome. Aiming to identify biomarkers for dengue prognosis, we extracted mRNA from the peripheral blood mononuclear cells of mild and severe dengue patients during the febrile stage of the disease to measure the expression levels of selected genes by quantitative polymerase chain reaction. The selected candidate biomarkers were previously identified by our group as differentially expressed in microarray studies. We verified that the mRNA coding for CFD, MAGED1, PSMB9, PRDX4 and FCGR3B were differentially expressed between patients who developed clinical symptoms associated with the mild type of dengue and patients who showed clinical symptoms associated with severe dengue. We suggest that this gene expression panel could putatively serve as biomarkers for the clinical prognosis of dengue haemorrhagic fever.

    New antiepileptic drugs (AEDs) that have been used in many other countries for more than 10 years have only recently became available for use in Japan. Gabapentin, topiramate, lamotrigine and levetiracetam were licensed for use in Japan between 2006 and 2010. Stiripentol for Dravet syndrome and rufinamide for Lennox-Gastaut syndrome were also approved in 2012 and 2013 as orphan drugs. Clinical trials of other new AEDs such as oxcarbazepine, vigabatrin, lacosamide, and perampanel are in progress. In this review, the general characteristics of the new AEDs are discussed with regards to their effectiveness, tolerability, drug interaction, safety and mechanisms of action. The effectiveness, of the new AEDs compared with established AEDs is also discussed. Clinical applications of the new AEDs, focusing on gabapentin, topiramate, lamotrigine and levetiracetam are also discussed based on our domestic experience as well as overseas reports.

    2015-12-01

    Acromegaly and pituitary gigantism are very rare conditions resulting from excessive secretion of growth hormone (GH), usually by a pituitary adenoma. Pituitary gigantism occurs when GH excess overlaps with the period of rapid linear growth during childhood and adolescence. Until recently, its etiology and clinical characteristics have been poorly understood. Genetic and genomic causes have been identified in recent years that explain about half of cases of pituitary gigantism. We describe these recent discoveries and focus on some important settings in which gigantism can occur, including familial isolated pituitary adenomas (FIPA) and the newly described X-linked acrogigantism (X-LAG) syndrome.

    Objective To analyze the clinic characteristics of varicella zoster myocarditis and to determine the diagnostic value of serum cardiac troponin I (cTnI ) on the disease. Methods Information of 58 hospitalized patients with varicella zoster was collected, and the incidence of varicella zoster myocarditis and clinic characteristics (ECG, cTnI, age and sex distribution, etc. ) were analyzed respectively. Results It was found that 36.2% of the patients developed myocarditis. The old and female persons were much more susceptible to varicella zoster myocarditis. All patients had responsive ECG manifestations, and the abnormal ST-T changes were more common than other ECG abnormalities. CTnI remained higher than normal and had significant diagnostic value. Most of the patients had good prognosis, only a few patients lasted a long time and even progressed into cardiomyopathy. Nearly all the patients came to see dermatologists when they felt ill initially. That would lead to more misdiagnosis. Conclusion Infection of varicella zoster can complicate myocarditis, we must pay more attention to the patients who suffer from varicella zoster especially in the aged and female; cTnI is an important and effective index for diagnosis of varicella zoster myocarditis.

    Full Text Available CONTEXT: During the last 12 years we have observed an increase in the frequency of Sydenham's chorea in our country. We have observed that some of our patients have presented recurrence of the chorea despite regular treatment with benzathine penicillin. OBJECTIVE: The aim of our study was to evaluate clinical and evolutive characteristics of Sydenham's chorea in a group of patients followed in our Pediatric Rheumatology Unit. TYPE OF STUDY: Retrospective study. SETTING: Section of Pediatric Rheumatology - Discipline of Allergy, Clinical Immunology and Rheumatology - Department of Pediatrics - UNIFESP - EPM. PARTICIPANTS: Two hundred and ninety patients with rheumatic fever followed between 1986 and 1999. METHODS: We reviewed the records of 290 patients with rheumatic fever followed between 1986 and 1999. All patients were diagnosed according to the revised Jones criteria (1992. We included 86 patients that presented Sydenham's chorea as one of the major criteria (one or more attacks and evaluated their clinical and evolutive characteristics as well the treatment. RESULTS: Fifty-five patients were girls and 31 were boys. The mean age at onset was 9.7 years and mean follow-up period was 3.6 years. The 86 Sydenham's chorea patients presented 110 attacks of chorea. We observed isolated chorea in 35% of the patients, and 25 (29% presented one or more recurrences. We included only 17 of the 25 patients for further analysis, with a total of 22 recurrences of which 14 were attacks of chorea, because it was not possible to precisely detect the interval between attacks in the other patients. The approximate interval between the attacks ranged from 4 to 96 months. In 71% of the patients there was no failure in the secondary prophylaxis with benzathine penicillin, which was performed every 3 weeks. CONCLUSION: Despite the regular use of secondary benzathine penicillin prophylaxis, children with rheumatic fever have a high risk of Sydenham's chorea

    @@ The severe acute respiratory syndrome (SARS) is an emerging and highly contagious infection caused by a newly discovered strain of coronavirus.1 Since the clinical case definition of SARS is similar to other severe atypical pneumonias, specific laboratory tests that can accurately diagnose SARS-associated coronavirus (SARS-CoV) infection are important. However, published data are insufficient to investigate whether clinically diagnosed SARS patients may include some non-SARS pneumonia. Therefore, we aimed to determine clinical and laboratory features to differentiate SARS patients from non-SARS pneumonias that could reduce misdiagnosis of SARS. A retrospective analysis of clinical and laboratory characteristics after the initial onset of SARS, as well as its convalescent-phase, was examined from clinically diagnosed 197 SARS patients.

    Background and Objectives Marfan syndrome (MFS) is a connective tissue disorder with autosomal dominant inheritance and a highly variable clinical spectrum. However, there are limited data available on the clinical features of Korean patients with MFS. The aim of the present study was to describe the clinical characteristics and outcomes of Korean patients with MFS. Subjects and Methods We included all patients who were diagnosed with MFS between January 1995 and May 2015 at a single tertiary medical center. Patients with an MFS-related disorder including MASS phenotype (myopia, mitral valve prolapse, borderline and non-progressive aortic root dilatation, skeletal findings, and striae), mitral valve prolapse syndrome, and ectopia lentis syndrome were excluded. A total of 343 Korean patients aged ≥15 years who satisfied the revised Ghent nosology were included. Results The mean patient age at diagnosis was 35.9±12.6 years and 172 (50.1%) patients were male. Median follow-up duration was 52.8 months. A total of 303 patients (88.6%) had aortic root dilatation with Z score ≥2 or aortic root dissection. Ectopia lentis was relatively less common (163 patients, 55.1%) and systemic score ≥7 was found in 217 patients (73.8%). Among 219 probands, a family history of MFS was present in 97 patients (44.5%) and sporadic cases in 121 patients (55.5%). Among the 157 probands who underwent genetic analysis, 141 (89.8%) had an FBN1 mutation associated with aortic root aneurysm/dissection. Aortic dissection (AD) or intramural hematoma (IMH) was identified in 110 patients (32.1%). Among the 221 patients without AD or IMH, descending aortic aneurysms were identified in 19 patients (8.6%). Two hundred thirteen patients (62%) underwent cardiovascular surgery of any type. Eight patients died during follow-up. Conclusion We described the clinical characteristics and outcomes of Korean MFS patients. Cardiovascular manifestations were commonly detected and FBN1 mutation was present

    Full Text Available Listeria monocytogenes causes foodborne illnesses through consumption of ready-to-eat foods. Although 135-201annual listeriosis cases have been estimated in Japan, the details regarding the clinical isolates such as infection source, virulence level, and other genetic characteristics, are not known. In order to uncover the trends of listeriosis in Japan and use the knowledge for prevention measures to be taken, the genetic characteristics of the past human clinical isolates needs to be elucidated. For this purpose, multilocus tandem-repeat sequence analysis (MLTSA and multi-virulence-locus sequence typing (MVLST were used in this study. The clinical isolates showed a variety of genetically distant genotypes, indicating they were from sporadic cases. However, the MVLST profiles of 7 clinical isolates were identical to those of epidemic clone (EC I isolates, which have caused several serious outbreaks in other countries, suggesting the possibility that they have strong virulence potential and originated from a single outbreak. Moreover, 6 Japanese food isolates shared their genotypes with ECI isolates, indicating that there may be risks for listeriosis outbreak in Japan. This is the first investigational study on genetic characteristics of Japanese listeriosis isolates. The listeriosis cases happened in the past are presumably sporadic, but it is still possible that some isolates with strong virulence potential have caused listeriosis outbreaks, and future listeriosis risks also exist.

    Paraquat is a nonselective contact herbicide of great toxicological importance, being associated with high mortality rates, mainly due to respiratory failure. We report the case of a 22-year-old male admitted to the emergency room with a sore throat, dysphagia, hemoptysis, and retrosternal pain after the ingestion of 50 mL of a paraquat solution, four days prior to admission. Chest CT scans revealed pulmonary opacities, pneumomediastinum, pneumothorax, and subcutaneous emphysema. The patient was submitted to two cycles of immunosuppressive therapy with cyclophosphamide, methylprednisolone, and dexamethasone. The pulmonary gas exchange parameters gradually improved, and the patient was discharged four weeks later. The clinical and tomographic follow-up evaluations performed at four months after discharge showed that there had been further clinical improvement. We also present a brief review of the literature, as well as a discussion of the therapeutic algorithm for severe paraquat poisoning. (author)

    Full Text Available Ozlem Balci Ophthalmology Department, Kolan Hospitalium Group, Istanbul, Turkey Purpose: To evaluate the clinical characteristics of patients with conjunctivochalasis (CCh. Methods and materials: This retrospective study enrolled 30 subjects diagnosed with conjunctivochalasis. Complete ophthalmic examination, including visual acuity assessment, slit-lamp examination, applanation tonometry, dilated funduscopy, tear break-up time, Schirmer 1 test, and fluorescein staining were performed in all patients. Age, sex, laterality, ocular history, symptoms, and clinical findings were recorded. Results: The study included 50 eyes from 30 cases. Ages ranged from 45 to 80 years, with a mean age of 65±10 years. CChs grading were as follows: 30 (60% eyes with grade 1 CCh; 15 (30% eyes with grade 2 CCh; and five (10% eyes with grade 3 CCh. CCh was located in the inferior bulbar conjunctiva in 45 (90% eyes, and in the remaining five (10% CCh was located in the superior bulbar conjunctiva. Ten (33.3% patients had no symptoms. Dryness, eye pain, redness, blurry vision, tired eye feeling, and epiphora were the symptoms encountered in the remaining twenty (63.6% patients. Altered tear meniscus was noted in all cases. The mean tear break-up time was 7.6 seconds. The mean Schirmer 1 test score was 7 mm. Pinguecula was found in ten patients. Conclusion: Dryness, eye pain, redness, blurry vision, and epiphora were the main symptoms in patients with CCh. Dryness, eye pain, and blurry vision were worsened during downgaze and blinking. So CCh should be taken into consideration in the differential diagnosis of chronic ocular irritation and epiphora. Keywords: ocular irritation, epiphora, dryness, eye pain, blurry vision

  12. Clinical definition of COPD exacerbations and classification of their severity.

    Caramori, Gaetano; Adcock, Ian M; Papi, Alberto

    2009-03-01

    A standardized definition of chronic obstructive pulmonary disease (COPD) exacerbation still represents an unmet need in respiratory medicine; definitions currently rely on clinical empiricism with little evidence-based scientific support. Exacerbations of COPD are certainly clear events in the mind of practicing physicians. However, when one tries to provide simple concepts such as their definition and classification of severity, one realizes how little we know. Current symptom- and event-based definitions of a COPD exacerbation, as well as the classifications of the severity of COPD exacerbations, all have their own limitations. Efforts to assess the efficacy of new therapies in the treatment and prevention of COPD exacerbations have been hampered by the lack of a widely agreed upon and consistently used definition. There is a need for greater investment in research on COPD exacerbations in order to promote a better understanding of COPD exacerbations.

    Increases in pancreatic enzyme levels after cardiovascular surgery were studied, and their clinical characteristics evaluated. The subjects were 128 patients who had undergone cardiovascular surgery (65 patients after valve replacement, 32 after coronary bypass surgery and 31 after aortic artificial graft replacement). The pancreatic enzyme (serum amylase and lypase) levels were monitored serially before and after operation, and amylase fractions were measured at their peaks. The relationships of the peak lypase level with underlying cardiac diseases, background factors, factors related to surgery, factors related to the extracorporeal circulation, presence or absence of symptoms, and treatments were examined. The amylase level exhibited biphasic changes consisting of a peak in which salivary glands amylase (S type) was dominant and a peak in which pancreatic amylase (P type) was dominant. The second peak coincided with the peak lypase and occurred mostly 3 to 10 days after operation. The peak lypase level exceeded the normal range in 78% of all the patients. It exceeded 564 U/l, 4 times the normal value in 28% of the patients, many of whom were symptomatic. So, we recommended that these cases should be treated as "postoperative pancreatitis". A high peak lypase level showed a significant correlation with the history of gallbladder and pancreatic diseases and diabetes mellitus among the background factors and emergency operation and the use of IABP among the surgery-related factors.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Mesenchymal stem cells (MSCs are bone marrow populating cells, different from hematopoietic stem cells, which possess an extensive proliferative potential and ability to differentiate into various cell types, including: osteocytes, adipocytes, chondrocytes, myocytes, cardiomyocytes and neurons. MSCs play a key role in the maintenance of bone marrow homeostasis and regulate the maturation of both hematopoietic and non-hematopoietic cells. The cells are characterized by the expression of numerous surface antigens, but none of them appears to be exclusively expressed on MSCs. Apart from bone marrow, MSCs are located in other tissues, like: adipose tissue, peripheral blood, cord blood, liver and fetal tissues. MSCs have been shown to be powerful tools in gene therapies, and can be effectively transduced with viral vectors containing a therapeutic gene, as well as with cDNA for specific proteins, expression of which is desired in a patient. Due to such characteristics, the number of clinical trials based on the use of MSCs increase. These cells have been successfully employed in graft versus host disease (GvHD treatment, heart regeneration after infarct, cartilage and bone repair, skin wounds healing, neuronal regeneration and many others. Of special importance is their use in the treatment of osteogenesis imperfecta (OI, which appeared to be the only reasonable therapeutic strategy. MSCs seem to represent a future powerful tool in regenerative medicine, therefore they are particularly important in medical research.

    2013-02-01

    To report clinical characteristics of high grade foveal hypoplasia. Patients with foveal hypoplasia of grade 3 or 4 on spectral domain optical coherence tomography according to a previously published scheme were enrolled. All patients underwent a full ophthalmologic assessment including visual acuity testing, slit lamp biomicroscopy, fundus examination, and evaluation of ocular alignment. The underlying causes of foveal hypoplasia were identified as albinism in five patients and aniridia in six patients. The mean logMAR visual acuity was 0.57 ± 0.24 (range 0.22-1.00) in the right eyes and 0.58 ± 0.21 (range 0.30-1.00) in the left eyes. On fundus examination in patients with albinism, two patients showed marked transparency, one patient showed moderate transparency, and two patients showed minimal transparency. Among six patients with aniridia, five patients showed normal macular pigmentation without macular reflex and one patient showed decreased macular pigmentation with no macular reflex. Patients with high grade macular hypoplasia tended to have poor visual acuities; however, the range of visual acuity was quite variable. Other factors associated with underlying disease could be the reason of this variability. Therefore, careful consideration should be given when assessing visual prognosis in foveal hypoplasia using optical coherence tomography.

    Simple, validated eczema severity scores are required for the evaluation of interventions. The Rajka & Langeland (R&L) scale is based on 3 domains (extent, course, and intensity); however, its validity is not yet confirmed. The aim of this study was to investigate the quality aspects of the R&L scale in clinical practice. In the first part of the study, experts and consumers judged the content validity of the scale. The second part of the study was performed with 87 children during a 4-month eczema school. Construct validity, internal consistency, sensitivity to change, time consumption and health-related quality of life variables were investigated. The content of the R&L scale was considered valid by 45 panellists. Inter- and intra-observer reliability was very good. Divergent construct validity was adequate, while convergent construct validity and internal consistency were inadequate. The R&L scale was able to define a significant improvement in eczema during the eczema school. The time required for completing the R&L assessment was significantly shorter than for objective Severity Scoring of Atopic Dermatitis (SCORAD). The R&L scale is a simple, fast, valid, reliable and sensitive tool for scoring of atopic dermatitis in everyday clinical practice.

    2014-06-01

    Recently, the genetic heterogeneity in osteogenesis imperfecta (OI), proposed in 1979 by Sillence et al., has been confirmed with molecular genetic studies. At present, 17 genetic causes of OI and closely related disorders have been identified and it is expected that more will follow. Unlike most reviews that have been published in the last decade on the genetic causes and biochemical processes leading to OI, this review focuses on the clinical classification of OI and elaborates on the newly proposed OI classification from 2010, which returned to a descriptive and numerical grouping of five OI syndromic groups. The new OI nomenclature and the pre-and postnatal severity assessment introduced in this review, emphasize the importance of phenotyping in order to diagnose, classify, and assess severity of OI. This will provide patients and their families with insight into the probable course of the disorder and it will allow physicians to evaluate the effect of therapy. A careful clinical description in combination with knowledge of the specific molecular genetic cause is the starting point for development and assessment of therapy in patients with heritable disorders including OI. © 2014 The Authors.

    2016-10-01

    To analyze retinal thickness changes in multiple system atrophy (MSA) and correlate changes with disease severity and subtypes of MSA. A total of 36 MSA (27 MSA-P and 9 MSA-C) patients and 71 healthy control subjects underwent general ophthalmologic examination and optical coherence tomography (OCT) scans. Peripapillary retinal nerve fiber layer (RNFL) thickness and perifoveal retinal thickness were analyzed separately. The generalized estimating equation model was used with age as a covariate to adjust for within-patient inter-eye correlations and the effect of age on retinal or RNFL thickness. Correlation analysis between RNFL, perifoveal thickness, and clinical parameters, the Unified MSA Rating Scale (UMSARS) and Global Disability Score (GDS), was also done. MSA patients showed significantly decreased peripapillary RNFL thickness in the inferior (P = 0.047) and inferotemporal (P = 0.017) sectors and significant perifoveal thinning in the superior outer sector (P = 0.042) compared to healthy controls. Both RNFL and perifoveal thinning were more marked and widespread in MSA-P than MSA-C patients. The UMSARS and GDS showed significant negative correlation with center and total macular perifoveal thickness and also the inferior and nasal outer sectors. Peripapillary RNFL and perifoveal retinal thinning were observed in MSA patients and retinal thinning correlated with the clinical severity of MSA. Structural changes in the retina may reflect the degree and pattern of neurodegeneration occurring in MSA.

    AIM: Elevation of alanine aminotransferase (ALT) level iscommonly seen among patients suffering from severe acute respiratory syndrome (SARS). We report the progression and clinical significance of liver derangement in a large cohort of SARS patient.METHODS: Serial assay of serum ALT was followed in patients who fulfilled the WHO criteria of SARS. Those with elevated ALT were compared with those with normal liver functions for clinical outcome. Serology for hepatitis B virus (HBV) infection was checked. Adverse outcomes were defined as oxygen desaturation, need of intensive care unit (ICU) and mechanical ventilation and death.RESULTS: Two hundred and ninety-four patients wereincluded in this study. Seventy (24%) patients had elevatedserum ALT on admission and 204 (69%) patients hadelevated ALT during the subsequent course of illness. Using peek ALT >5xULN as a cut-off and after adjusting for potential confounding factors, the odds ratio of peek ALT >5x ULN for oxygen desaturation was 3.24 (95%CI 1.23-8.59, P = 0.018), ICU care was 3.70 (95%CT 1.38-9.89, P = 0.009), mechanical ventilation was 6.64 (95%CI 2.22-19.81, P = 0.001) and death was 7.34 (95%CI 2.28-24.89, P = 0.001). Ninety-three percent of the survived patients had ALT levels normalized or were on the improving trend during follow-up. Chronic hepatitis B was not associated with worse clinical outcomes. CONCLUSION: Reactive hepatitis is a common complication of SARS-coronavirus infection. Those patients with severehepatitis had worse clinical outcome.

    DeBoer, Mark D; Gurka, Matthew J

    2017-01-01

    The metabolic syndrome (MetS) is marked by abnormalities in central obesity, high blood pressure, high triglycerides, low high-density lipoprotein-cholesterol, and high fasting glucose and appears to be produced by underlying processes of inflammation, oxidative stress, and adipocyte dysfunction. MetS has traditionally been classified based on dichotomous criteria that deny that MetS-related risk likely exists as a spectrum. Continuous MetS scores provide a way to track MetS-related risk over time. We generated MetS severity scores that are sex- and race/ethnicity-specific, acknowledging that the way MetS is manifested may be different by sex and racial/ethnic subgroup. These scores are correlated with long-term risk for type 2 diabetes mellitus and cardiovascular disease. Clinical use of scores like these provide a potential opportunity to identify patients at highest risk, motivate patients toward lifestyle change, and follow treatment progress over time.

    AIM: To summarize clinical features of probable severe acute respiratory syndrome (SARS) in Beijing.METHODS: Retrospective cases involving 801 patients admitted to hospitals in Beijing between March and June 2003, with a diagnosis of probable SARS, moderate type.The series of clinical manifestation, laboratory and radiograph data obtained from 801 cases were analyzed. RESULTS: One to three days after the onset of SARS, the major clinical symptoms were fever (in 88.14% of patients), fatigue, headache, myalgia, arthralgia (25-36%), etc. The counts of WBC (in 22.56% of patients) lymphocyte (70.25%)and CD3, CD4, CD8 positive T cells (70%) decreased. From 4-7 d, the unspecific symptoms became weak; however, the rates of low respiratory tract symptoms, such as cough (24.18%), sputum production (14.26%), chest distress (21.04%) and shortness of breath (9.23%) increased, so did the abnormal rates on chest radiograph or CT. The low counts of WBC, lymphocyte and CD3, CD4, CD8 positiveT cells touched bottom. From 8 to 16 d, the patients presented progressive cough (29.96%), sputum production (13.09%), chest distress (29.96%) and shortness of breath (35.34%). All patients had infiltrates on chest radiograph or CT, some even with multi-infiltrates. Two weeks later, patients' respiratory symptoms started to alleviate, the infiltrates on the lung began to absorb gradually, the counts of WBC, lymphocyte and CD3, CD4, CD8 positive T cells were restored to normality.CONCLUSION: The data reported here provide evidence that the course of SARS could be divided into four stages, namely the initial stage, progressive stage, fastigium and convalescent stage.

    1999-08-27

    FG syndrome is a rare X-linked recessive form of mental retardation, first described by Opitz and Kaveggia in 1974. Based on over 50 reported cases, FG syndrome is associated with agenesis of the corpus callosum, minor facial anomalies (high, broad forehead with frontal cowlick, ocular hypertelorism, down-slanted palpebral fissures, and small cupped auricles), relative macrocephaly, broad thumbs and halluces, and prominent fetal fingertip pads. Affected individuals manifest neonatal hypotonia and severe constipation, which usually resolves during mid-childhood. The hypotonia with joint hyperlaxity evolves into spasticity with joint contractures in later life. Affability, hyperactivity, and excessive talkativeness are noted frequently in patients with FG syndrome. Recently, we described three additional families (six additional patients) with FG syndrome who support the localization of a gene for the FG syndrome in chromosome region Xq12-q21 [Graham JM Jr, Tackels D, Dibbern K, Superneau D, Rodgers C, Corning K, Schwartz CE. 1998. Am J Med Genet 80:145-156.]. Using these same families and one additional sporadic case of FG syndrome, we compared behavioral and personality characteristics of 6 FG boys with other boys with syndromic and nonsyndromic mental retardation: eight with Down syndrome, seven with Prader-Willi syndrome, eight with nonspecific mental retardation, and 13 with Williams syndrome. Using the Vineland Adaptive Behavior Scales, the Reiss Personality Profiles, and the Achenbach Child Behavior Checklist, parents were asked to characterize the behavior and personality of their boys from ages 4 to 10 years. When compared with Williams syndrome, the FG boys had fewer internalizing behaviors and were significantly less anxious and withdrawn but had similar socially oriented, attention-seeking behaviors. On the Reiss Profile, FG boys were also quite similar to Williams syndrome boys. On the Vineland Scales, FG boys demonstrated significant relative strengths

    OBJECTIVE To analyse the clinical characteristics of malignant granuloma(MG) and evaluate its treatment.METHODS From March 1985 to May 1998, 101 cases of malignant granuloma were treated with radiation (RT) alone or radiotherapy followed by chemotherapy or chemotherapy followed by radiotherapy. For chemotherapy, a CCNU, COMP (CTX, VCR, MTX, PDN) or CHOP (CTX,ADM, VCR, PDN) regimen was given. Radiation was directed through the anterior field of the nose mainly for nasal and paranasal sinus malignant granuloma, and through the faciocervical field for malignant granuloma of Walderyer's ring or for patients with cervical lymphadenectasis. Total dose was 45-65 Gy over 5-6 weeks.RESULTS The overall 3-year, 5-year and 10-year survival rates were 78.2%, 56.1% and 39.7% respectively. The 5-year survival rate was: RT group 60.3%, RT + CHOP or CHOP + RT group 64.7% (P >0.05), RT +CCNU group 40%, and RT + COMP group 33.3%. The 5-year survival rates of patients with one involved focus and more than 2 involved foci were 75.6%(34/45) and 39.3% (22/56) (P<0.001). The 5-year survival rates of patients with or without body symptoms were 39.6% (18/48) and 67.9%(36/53) (P<0.05). The 5-year survival rate of the 50-60 Gy group and the <50Gy group were 60.1% (40/66) and 20% (1/5)(P <0.05). The local and regional recurrence rate was 20.8 % (21/101 ).CONCLUSION Radiotherapy alone should be the treatment of choice for patients with one site involvement and without body symptoms. Radiation fields should be large enough to include the potentially involved sites. The recommended dose is 50-60 Gy over 5-6 weeks. It is suggested that patients with more than 2 foci involvement and those with body symptoms should receive the combination therapy.

    Full Text Available Background and Aims: Infection with hepatitis A virus is still one of the most common causes of hepatitis worldwide. The clinical manifestation of acute hepatitis A (AHA in adults can vary greatly, ranging from asymptomatic infection to severe and fulminant hepatitis. The aim of this study was to describe the demographic, clinical characteristics, laboratory features and hospital outcome of adult patients with AHA over a consecutive period of 4 years within an area from Eastern European country. Methods: Two hundred and two adult patients diagnosed with AHA were retrospective, observational and analytic analized over a period of 4 years. Based on prothrombin time less than 50, the study group was stratified in medium (79.2% and severe forms (20.8%. We investigated the clinical, laboratory and epidemiological features. Statistical analysis were applied to compare the medium and severe forms of AHA. Results: Most patients (72.7% were younger than 40 years. The main symptoms included: dyspepsia (72.07%, jaundice (86.63%, asteno-adynamia (86.72%, and flu-like symptoms (53.46%. The hemorrhagic cutaneous-mucous manifestations (6.93% associated with the severe forms of AHA (OR =12.19, 95%CI -3.59 - 41.3, p =0.001. We found statistically significant differences for PT (p <0.001, INR (p <0.001, TQ (p <0.001, ALAT (p <0.001, ASAT (p <0.001, ALP (p <0.001 and platelets (p =0.009 between severe and medium AHA forms. We found that TQ, INR, ALAT and ASAT have the highest diagnostic values, statistically significant (p <0.05 for severe AHA forms with AUC (0.99, 0.99, 0.72, 0.70 at values of sensitivity (95%, 90.5%, 89%, 95% and specificity (98%, 99%, 88%,94%. Conclusions Medium severity AHA forms were found in most of the study group patients (79.2%. The severe AHA forms were associated with hemorrhagic cutaneous-mucous manifestations (OR =12.19, p =0.001. The univariate analysis proved a negatively statistically significant correlation between IP and ALAT

    Full Text Available Acute pancreatitis (AP is a common disease in the department of gastroenterology with variable severity, from being mild and self-limited to severe and fatal. The early diagnosis and accurate prediction of AP severity are of great importance. Our primary observation showed that fatty liver (FL was frequently detected in patients with AP. In this retrospective study, we aimed to evaluate the relation between FL and the severity and outcomes of AP. The medical records of 2671 patients with AP were reviewed retrospectively, and characteristics of AP patients were recorded. FL was assessed by abdominal CT scan, and AP patients were categorized by the occurrence of FL for the analysis. The variation of mortality, clinical severity and the appearance of CT were analyzed between the non-FL group and FL groups. Compared with patients without FL, an obviously higher rate of death and higher frequency of severe AP (SAP and necrotizing AP (ANP were observed in patients with FL, as well as the incidence of local complications and systemic complications. Taking obesity into consideration, a higher rate of death and more severe AP were found in patients with FL, no matter whether they were obese or not. Alcoholic fatty liver (AFL and non-alcoholic fatty liver (NAFL were also separated for comparison in this study; the incidence of ANP and the clinical severity had no significant difference between the AFL and NAFL groups. In conclusion, FL could influence the severity and clinical outcome and may play a prognostic role in AP. This study is of clinical significance, because few reports have been previously issued on FL and AP.

    Characteristics of contemporary climate change in the Tibetan Plateau have been investigated based on the observational data of monthly mean air temperature, monthly mean maximum and minimum air temperatures, and precipitation amount at 217 stations in the Plateau and its adjacent areas in 1951-1998, in which the temperature data at Lhasa, Lanzhou, Kunming and Chengdu were extended to a period of 1935-1950. The following conclusions can be drawn. (1) The air temperature in the Tibetan Plateau decreased from the 1950s to the 1960s, afterwards it began warming up to the 1990s. The data at the Lhasa Station beginning from 1935 have indicated that the air temperature at the station was the highest in the 1940s, then it became cooling until the 1960s. After the 1960s, it began warming until the 1990s. However, the air temperature at Lhasa in the 1990s still did not reach as high as in the 1940s. (2) Since the 1960s, there has existed a cooling belt below 3000 m altitude above sea level, which is located in ea

    Full Text Available Background: Severe, drug-resistant gastroparesis is a debilitating condition. Several, but not all, patients can get significant relief from nausea and vomiting by gastric electrical stimulation (GES. A trial of temporary, endoscopically delivered GES may be of predictive value to select patients for laparoscopic-implantation of a permanent GES device. Materials and Methods: We conducted a clinical audit of consecutive gastroparesis patients, who had been selected for GES, from May 2008 to January 2012. Delayed gastric emptying was diagnosed by scintigraphy of ≥50% global improvement in symptom-severity and well-being was a good response. Results: There were 71 patients (51 women, 72% with a median age of 42 years (range: 14-69. The aetiology of gastroparesis was idiopathic (43 patients, 61%, diabetes (15, 21%, or post-surgical (anti-reflux surgery, 6 patients; Roux-en-Y gastric bypass, 3; subtotal gastrectomy, 1; cardiomyotomy, 1; other gastric surgery, 2 (18%. At presentation, oral nutrition was supplemented by naso-jejunal tube feeding in 7 patients, surgical jejunostomy in 8, or parenterally in 1 (total 16 patients; 22%. Previous intervention included endoscopic injection of botulinum toxin (botox into the pylorus in 16 patients (22%, pyloroplasty in 2, distal gastrectomy in 1, and gastrojejunostomy in 1. It was decided to directly proceed with permanent GES in 4 patients. Of the remaining, 51 patients have currently completed a trial of temporary stimulation and 39 (77% had a good response and were selected for permanent GES, which has been completed in 35 patients. Outcome data are currently available for 31 patients (idiopathic, 21 patients; diabetes, 3; post-surgical, 7 with a median follow-up period of 10 months (1-28; 22 patients (71% had a good response to permanent GES, these included 14 (68% with idiopathic, 5 (71% with post-surgical, and remaining 3 with diabetic gastroparesis.

    Idiopathic portal hypertension is one of the interesting causes of portal hypertension. Even in very developed medical centers, this disorder is still one of the most important misdiagnoses of clinical practice. To inexperienced physicians, presenting esophageal varices and upper gastrointestinal bleeding usually prompt an unfortunate diagnosis of cirrhosis. A heterogenous clinical presentation and progression of this disorder should be recognized by physicians, and management should be directed towards some specific problems confined to this disorder. Although a genetic basis and other factors are implicated in its pathogenesis, exact underlying mechanism(s) is (are) unknown. In this review, we discuss the heterogeneity of idiopathic portal hypertension, its etiopathogenesis, clinical presentation and management issues. With the expectation of an excellent prognosis, a practicing gastroenterologist should be aware that "not all varices mean cirrhosis".

    Full Text Available Introduction: Intensive care mortality of HIV-positive patients has progressively decreased. However, critically ill HIV-positive patients with sepsis present a worse prognosis. To better understand this condition, we propose a study comparing clinical, etiological and inflammatory data, and the hospital course of HIV-positive and HIV-negative patients with severe sepsis or septic shock. Methods: A prospective observational study enrolling patients with severe sepsis or septic shock associated or not with HIV infection, and admitted to intensive care unit (ICU. Clinical, microbiological and inflammatory parameters were assessed, including C-reactive protein (CRP, procalcitonin (PCT, interleukin-6, interleukin-10 and TNF-α. Outcome measures were in-hospital and six-month mortality. Results: The study included 58 patients with severe sepsis/septic shock admitted to ICU, 36 HIV-positive and 22 HIV-negative. All HIV-positive patients met the criteria for AIDS (CDC/2008. The main foci of infection in HIV-positive patients were pulmonary and abdominal (p=0.001. Fungi and mycobacteria were identified in 44.4% and 16.7% of HIV-positive patients, respectively. In contrast, the main etiologies for sepsis in HIV-negative patients were Gram-negative bacilli (36.4% and Gram-positive cocci (36.4% (p=0.001. CRP and PCT admission concentrations were lower in HIV-positive patients (130 vs. 168 mg/dL p=0.005, and 1.19 vs. 4.06 ng/mL p=0.04, respectively, with a progressive decrease in surviving patients. Initial IL-10 concentrations were higher in HIV-positive patients (4.4 pg/mL vs. 1.0 pg/mL, p=0.005, with moderate accuracy for predicting death (area under receiver-operating characteristic curve =0.74. In-hospital and six-month mortality were higher in HIV-positive patients (55.6 vs. 27.3% p=0.03, and 58.3 vs. 27.3% p=0.02, respectively. Conclusions: The course of sepsis was more severe in HIV-positive patients, with distinct clinical, etiological and

    To describe the clinical and epidemiological characteristics of patients with severe infectious keratitis in Asunción, Paraguay between April 2009 and September 2011. All patients with the clinical diagnosis of severe keratitis (ulcer ≥2 mm in size and/or central location) were included. Empiric treatment consisted of topical antibiotics and antimycotics; in cases of advanced keratitis, fortified antibiotics were used. After microbiological analysis, treatment was changed if indicated. In total 48 patients (62.5 % males, 25 % farmers) were included in the analysis. A central ulcer was found in 81.3 % (n = 39). The median delay between onset of symptoms and time of first presentation at our institution was 7 days (range 1-30 days). Fungal keratitis was diagnosed in 64.5 % (n = 31) of patients, of which Fusarium sp. (n = 17) was the most common. Twenty-one patients (43.8 %) reported previous trauma to the eye. The globe could be preserved in all cases. While topical therapy only was sufficient in most patients, a conjunctival flap was necessary in six patients suffering from fungal keratitis. The high rate of fungal keratitis in this series is remarkable, and microbiological analysis provided valuable information for the appropriate treatment. In this setting, one has to be highly suspicious of fungal causes of infectious keratitis.

    Full Text Available Plasmodium falciparum is a major cause of severe malaria in Southeast Asia, however, there is limited information regarding clinical factors associated with the severity of falciparum malaria from this region. We performed a retrospective case-control study to compare clinical factors and outcomes between patients with severe and non-severe malaria, and to identify clinical factors associated with the requirement for intensive care unit (ICU admission of patients with severe falciparum malaria among hospitalized adults in Southeast Asia. A total of 255 patients with falciparum malaria in the Hospital for Tropical Diseases in Bangkok, Thailand between 2006 and 2012 were included. We identified 104 patients with severe malaria (cases and 151 patients with non-severe malaria (controls. Patients with falciparum malaria with following clinical and laboratory characteristics on admission (1 referrals, (2 no prior history of malaria, (3 body temperature of >38.5°C, (4 white blood cell counts >10×10(9/µL, (5 presence of schizonts in peripheral blood smears, and (6 albumin concentrations of <3.5 g/dL, were more likely to develop severe malaria (P<0.05. Among patients with severe malaria, patients who met ≥3 of the 2010 WHO criteria had sensitivity of 79.2% and specificity of 81.8% for requiring ICU admission. Multivariate analysis identified the following as independent associated factors for severe malaria requiring ICU admission; (1 ethnicity of Thai [odds ratio (OR = 3.601, 95% confidence interval (CI = 1.011-12.822] or Myanmar [OR = 3.610, 95% CI = 1.138-11.445]; (2 referrals [OR = 3.571, 95% CI = 1.306-9.762]; (3 no prior history of malaria [OR = 5.887, 95% CI = 1.354-25.594]; and (4 albumin concentrations of <3.5 g/dL [OR = 7.200, 95% CI = 1.802-28.759]. Our findings are important for the clinical management of patients with malaria because it can help early identification of patients that could develop

    Holoprosencephaly is a brain defect resulting from incomplete cleavage of the embryonic forebrain. It involves forebrain and facial malformations that can range from mild to severe. The epidemiology of holoprosencephaly is largely unknown. Published prevalence estimates have been derived from clinic-based case series, and suggested risk factors for holoprosencephaly have been identified in case reports, without confirmation from systematically conducted population-based studies. Using data from a population-based birth defects registry in California, we described the epidemiologic and clinical characteristics of cytogenetically and phenotypically distinct types of holoprosencephaly. A total of 121 cases was identified among a cohort of 1,035,386 live births and fetal deaths. The prevalence of holoprosencephaly was 1.2 per 10,000 births (95% confidence interval 1.0-1.4 per 10,000). Of all cases, 41% (50/121) had a chromosomal abnormality, most commonly Trisomy 13. Among the 71 cytogenetically apparently normal cases, 18 had recognizable syndromes and the remaining 53 were of unknown cause. Among the cytogenetically abnormal cases, females had a greater risk than males (odds ratio = 2.3, 95% confidence interval [1.2, 4.4]). Among the cytogenetically normal cases, increased risks were observed among Hispanic whites (OR = 1.8 [0.9, 3.6]) and cases whose mother was born in Mexico (OR = 2.2 [1.0, 4.5]). Approximately 46% of all cases had alobar holoprosencephaly, the most severe form of the forebrain malformation. The facial phenotype did not strongly predict the severity of the brain defect; however, severity was inversely correlated with length of survival. This study is the first to present findings based on such a large population-based series of infants/fetuses affected by holoprosencephaly, and demonstrates the importance of investigating the component subgroups of this rare phenotype. 47 refs., 7 tabs.

    Community-acquired Acinetobacter baumannii (CA-Ab) is a rare but serious cause of community-acquired pneumonia in tropical regions of the world. CA-Ab infections predominantly affect individuals with risk factors, which include excess alcohol consumption, diabetes mellitus, smoking and chronic lung disease. CA-Ab pneumonia presents as a surprisingly fulminant course and is characterized by a rapid onset of fever, severe respiratory symptoms and multi-organ dysfunction, with a mortality rate reported as high as 64%. It is unclear whether the distinct clinical syndrome caused by CA-Ab is because of host predisposing factors or unique bacterial characteristics, or a combination of both. Deepening our understanding of the drivers of overwhelming CA-Ab infection will provide important insights into preventative and therapeutic strategies.

    Cohen, Laura P; Pasquale, Louis R

    2014-06-02

    Glaucoma is a neurodegenerative disorder in which degenerating retinal ganglion cells (RGC) produce significant visual disability. Clinically, glaucoma refers to an array of conditions associated with variably elevated intraocular pressure (IOP) that contributes to RGC loss via mechanical stress, vascular abnormalities, and other mechanisms, such as immune phenomena. The clinical diagnosis of glaucoma requires assessment of the ocular anterior segment with slit lamp biomicroscopy, which allows the clinician to recognize signs of conditions that can produce elevated IOP. After measurement of IOP, a specialized prismatic lens called a gonioscope is used to determine whether the angle is physically open or closed. The structural manifestation of RGC loss is optic nerve head atrophy and excavation of the neuroretinal rim tissue. Treatment is guided by addressing secondary causes for elevated IOP (such as inflammation, infection, and ischemia) whenever possible. Subsequently, a variety of medical, laser, and surgical options are used to achieve a target IOP.

    Hypotonia is a common occurrence in pediatrics, especially in the neonatal period. The hypotonic neonate represents a diagnostic challenge for the general pediatrician because hypotonia may be caused by a lesion at any level in the neuraxis: (1) central nervous system (CNS), (2) peripheral nerves (PN), (3) neuromuscular junction, or (4) muscles. Distinguishing among these pathologies is a particularly arduous task. This review will discuss the clinical approach to neonatal hypotonia with emphasis on disorders of the peripheral nervous system and muscle, and the importance of the electrophysiological study as a diagnostic test.

    Candida organisms live on the skin and mucous membranes of up to 75 percent of the population. They can live commensally without causing harm or can change to an aggressive form and invade tissue, causing both acute and chronic disease in the host. Oropharyngeal candidiasis manifests clinically as acute pseudomembranous, acute atrophic, chronic atrophic, chronic hypertrophic/hyperplastic, and angular cheilitis. Systemic infection leading to candidemia can be devastating and cause up to a 60 percent mortality rate in medical or post-surgical intensive care wards. Oral nystatin, clotrimazole, and fluconazole usually provide appropriate therapy; although resistance to medications is increasing, particularly in immunocompromised hosts.

Brain MRI was performed in all patients and revealed multiple hyperintense supratentorial brain lesions on T2/FLAIR images. 85.7% of patients had cortical and/or subcortical white matter lesions which were bilateral and asymmetric in location and size. Conclusion: ADEM although rare must be considered in children with acute onset of neurological signs and symptoms and must be distinguished from any acute neurological insult.

    Acute severe mitral regurgitation often goes unrecognized as an emergency requiring prompt, lifesaving treatment. Its causes, physical signs, natural history, echocardiographic features, and findings on chest roentgenography, electrocardiography, and nuclear scintigraphic scanning are reviewed. Acute severe mitral insufficiency can be differentiated from chronic severe mitral insufficiency by noninvasive two-dimensional echocardiography. M-mode echocardiography is a valuable tool in evaluating mitral prosthetic paravalvular regurgitation.

    Pharmacodynamic studies revealed that 150 mg of roxatidine acetate were optimal in suppressing gastric acid secretion, and that a single bedtime dose of 150 mg was more effective than a dose of 75 mg twice daily in terms of inhibiting nocturnal acid secretion. When administered orally as a capsule containing a granule formulation, the drug displayed modified-release properties, which led to a sustained suppression of gastric acid secretion. Clinical trials revealed that roxatidine acetate, 75 mg twice daily and 150 mg at night, was highly effective in healing duodenal and gastric ulcers and in reducing ulcer pain, over 4, 6, and 8 weeks of therapy. A steady reduction in diameter was observed in those ulcers not completely healed during therapy. The single bedtime dose regimen, while producing the same degree of healing as the divided daily dose during controlled clinical trials, may be of greater value in therapeutic use owing to improved patient compliance. In all efficacy criteria (cure, reduction in ulcer size, and pain relief) there was no significant difference between roxatidine acetate in a total daily dose of 150 mg, ranitidine in a total daily dose of 300 mg, and cimetidine in a total daily dose of 800 mg. Prevention of gastric and duodenal ulcer relapse was achieved by roxatidine acetate, 75 mg at night for 6 months, in about 70% of patients, as determined in open, pilot studies--a rate comparable to those reported for cimetidine and ranitidine. Roxatidine acetate shares with ranitidine an improved safety profile when compared with cimetidine. Human pharmacology studies and short-term and long-term clinical trials have all shown that roxatidine acetate is an exceptionally well tolerated compound, without the antiandrogenic activity and interference with hepatic drug metabolism which have characterized cimetidine treatment. A reason for the improved safety profile of roxatidine acetate may be its greater potency than cimetidine (six times less potent) and

  12. Huntington's disease: clinical characteristics, pathogenesis and therapies.

    2007-02-01

    Huntington's disease is a devastating disorder with no known cure. The disease results from an expanded sequence of CAG repeats in the huntingtin gene and leads to a movement disorder with associated cognitive and systemic deficits. Huntington's disease is diagnosed by genetic testing and disease progression can be followed with a variety of imaging modalities. The accumulation of aggregated huntingtin with associated striatal degeneration is evident at autopsy. The pathophysiology of Huntington's disease remains unknown, although protein aggregation, excitotoxicity, deficits in energy metabolism, transcriptional dysregulation and apoptosis may all be involved. Current pharmacologic therapy for Huntington's disease is limited and exclusively symptomatic. However, the disease is being heavily researched, and a wide range of disease-modifying therapies is currently under development. The efficacy of these therapies is being evaluated in transgenic models of Huntington's disease and in preliminary clinical trials.

    Twenty-three cases of ovarian fibroma, comprising 3% of all benign tumors seen over a 20-year period, were analyzed. It was unilateral in all cases affecting more commonly the left ovary (70%). Whilst a majority of cases (77%) were encountered in the reproductive age group, the tumor was rare before the second decade. Only in 13% of cases was ascitis clinically detectable. This was not influenced by the size and weight (average of 9.3 x 10.8 x 11.1 cm and 959 g, respectively) of the tumors; a smooth-surfaced tumor was, however, associated with a greater amount of peritoneal fluid. Varying degrees of calcification in some tumors are detectable on ultrasonography and occasionally on abdominal radiography. The classical Meig's Syndrome was seldom encountered. The histopathological features, diagnostic problems and management are discussed.

    Seven patients with scimitar syndrome underwent retrospective clinical and echocardiographic examination. The findings were: respiratory infection with dyspnea on moderate exercise in 90%, scimitar sign in four (57%), dextrocardia in five (71%), and interatrial septal defect in five (71%), one of whom had patent ductus arteriosus. Overall, two patients had patent ductus arteriosus: one also had aortic coarctation and the other, a bicuspid aortic valve. Dilation of the right cavities was found in five (71%) and blunt edge in five (71%). In two patients, anomalous drainage was into the right atrium; in another two, into the inferior vena cava; and in three, towards the junction of the right atrium and the inferior vena cava. In three patients, drainage was obstructed. Six patients with cardiac abnormalities proceeded to surgery. Scimitar syndrome is a rare entity. In the large majority of patients (86%), diagnosis and follow-up can be performed echocardiographically.

    Background Severe burn-blast combined injury is a great challenge to medical teams for its high mortality. The aim of this study was to elucidate the clinical characteristics of the injury and to present our clinical experiences on the treatment of such cases.Methods Five patients with severe burn-blast combined injuries were admitted to our hospital 77 hours post-injury on June 7, 2005. The burn extent ranged from 80% to 97% (89.6%±7.2%) of TBSA (full-thickness burns 75%-92%(83.4%±7.3%)). All the patients were diagnosed as having blast injury and moderate or severe inhalation injury. Functions of the heart, liver, kidney, lung, pancreas and coagulation were observed. Autopsy samples of the heart, liver, and lungs were taken from the deceased. Comprehensive measures were taken during the treatment, including protection of organ dys function, use of antibiotics, early anticoagulant treatment, early closure of burn wounds, etc. All the data were analyzed statistically with t test.Results One patient died of septic shock 23 hours after admission (four days after injury), the others survived.Dysfunction of the heart, liver, lungs, pancreas, and coagulation were found in all the patients on admission, and the functions were ameliorated after appropriate treatments.Conclusions Burn-blast combined injury may cause multiple organ dysfunctions, especially coagulopathy. Proper judgment of patients' condition, energetic anticoagulant treatment, early closure of burn wounds, rational use of antibiotics, nutritional support, intensive insulin treatment, timely and effective support and protection of organ function are the most important contributory factors in successful treatment of burn-blast combined injuries.

    BACKGROUND: The clinical manifestations of Wernicke encephalopathy(WE) are atypical and short of effective auxiliary examination means. The effects of magnetic resonance imaging (MRI) in the diagnosis of WE have been reported suecessively. But its imageological detection needs to be further investigated.OBJECTIVE: To analyze the eharacteristics of clinical manifestations, skull MRI examination and pathological results in patients with WE.DESTGN: Retrospective analysis.SETTTNG: The General Hospital of Chinese PLA.PARTTCTPANTS: Ten patients of WE admitted to the Department of Neurology, General Hospital of Chinese PLA were recruited. Among them, five patients were diagnosed pathologically after death. Their pathological changes accorded with the pathological characteristics of WE. The other 5 patients were diagnosed clinically before death. Their pathological changes accorded with clinical and imageological manifestations and had definite reaction to the treatment of thiamine. Ten patients, 7 males and 3 females, were aged (47±13) years ranging from 33 to 73 years. Their disease courses averaged 6 weeks ranging from 3 to 10 weeks. They all were non-alcoholics. Four patients developed WE after acute pancreatitis, two patients after the recurrence of gastric cancer, two patients after cholecystectomy, one patient after hepatitis medicamentosa, one patient after Alzheimer disease. Informed consents were obtained from all the patients and their relatives.METHODS: After admission, clinical manifestations of patients were observed and recorded. Five patients underwent skull MRI examination and their detected results were recorded. Five dead patients underwent autopsy and brain pathological examinations. Neuropathological examination involved cerebrum, cerebellum and brain stem.MATN OUTCOME MEASURES: Clinical manifestations, MRI examination results, pathological analysis results and prognosis of all the patients.RESULTS: Ten patients with WE were involved in the final

    Full Text Available BACKGROUND: Elevation of aspartate aminotransferase (AST and alanine aminotransferase (ALT is prominent in acute dengue illness. The World Health Organization (WHO 2009 dengue guidelines defined AST or ALT ≥ 1000 units/liter (U/L as a criterion for severe dengue. We aimed to assess the clinical relevance and discriminatory value of AST or ALT for dengue hemorrhagic fever (DHF and severe dengue. METHODOLOGY/PRINCIPAL FINDINGS: We retrospectively studied and classified polymerase chain reaction positive dengue patients from 2006 to 2008 treated at Tan Tock Seng Hospital, Singapore according to WHO 1997 and 2009 criteria for dengue severity. Of 690 dengue patients, 31% had DHF and 24% severe dengue. Elevated AST and ALT occurred in 86% and 46%, respectively. Seven had AST or ALT ≥ 1000 U/L. None had acute liver failure but one patient died. Median AST and ALT values were significantly higher with increasing dengue severity by both WHO 1997 and 2009 criteria. However, they were poorly discriminatory between non-severe and severe dengue (e.g., AST area under the receiver operating characteristic [ROC] curve=0.62; 95% confidence interval [CI]: 0.57-0.67 and between dengue fever (DF and DHF (AST area under the ROC curve=0.56; 95% CI: 0.52-0.61. There was significant overlap in AST and ALT values among patients with dengue with or without warning signs and severe dengue, and between those with DF and DHF. CONCLUSIONS: Although aminotransferase levels increased in conjunction with dengue severity, AST or ALT values did not discriminate between DF and DHF or non-severe and severe dengue.

    Severe Candida esophagitis (CE) may lead to development of strictures, hemorrhage, esophagotracheal fistula, and a consequent decrease in quality of life. Although the severity of CE has been classified based on macroscopic findings on endoscopy, the clinical significance remains unknown. The aim of the study was to elucidate the predictive clinical factors for endoscopic severity of CE. Patients who underwent upper endoscopy and answered questionnaires were prospectively enrolled. Smoking, alcohol, human immunodeficiency virus (HIV) infection, diabetes mellitus, chronic renal failure, liver cirrhosis, systemic steroids use, proton pump inhibitor use, H2 blocker use, and gastrointestinal (GI) symptoms were assessed on the same day of endoscopy. GI symptoms including epigastric pain, heartburn, reflux, hunger cramps, nausea, dysphagia, and odynophagia were assessed on a 7-point Likert scale. Endoscopic severity was classified as mild (Kodsi's grade I/II) or severe (grade III/IV). Of 1855 patients, 71 (3.8%) were diagnosed with CE (mild, n = 48; severe, n = 23). In the CE patients, 50.0% (24/48) in the mild group and 23.1% (6/23) in the severe group did not have any GI symptoms. In HIV-infected patients (n = 17), a significant correlation was found between endoscopic severity and declining CD4 cell count (Spearman's rho = -0.90; P < 0.01). Multivariate analysis revealed that GI symptoms (odds ratio [OR], 3.32) and HIV infection (OR, 3.81) were independently associated with severe CE. Patients in the severe group experienced more epigastric pain (P = 0.02), reflux symptoms (P = 0.04), dysphagia (P = 0.05), and odynophagia (P < 0.01) than those in the mild group. Of the GI symptoms, odynophagia was independently associated with severe CE (OR 9.62, P = 0.02). In conclusion, the prevalence of CE in adults who underwent endoscopy was 3.8%. Silent CE was found in both mild and severe cases. Endoscopic severity was associated with

    Ortiz, Justin R; Jacob, Shevin T; West, T Eoin

    2013-09-01

    The 2009 influenza A (H1N1) pandemic highlighted the importance of quality hospital care of the severely ill, yet there is evidence that the impact of the 2009 pandemic was highest in low- and middle-income countries with fewer resources. Recent data indicate that death and suffering from seasonal influenza and severe illness in general are increased in resource-limited settings. However, there are limited clinical data and guidelines for the management of influenza and other severe illness in these settings. Life-saving supportive care through syndromic case management is used successfully in high-resource intensive care units and in global programs such as the Integrated Management of Childhood Illness (IMCI). While there are a variety of challenges to the management of the severely ill in resource-limited settings, several new international initiatives have begun to develop syndromic management strategies for these environments, including the World Health Organization's Integrated Management of Adult and Adolescent Illness Program. These standardized clinical guidelines emphasize syndromic case management and do not require high-resource intensive care units. These efforts must be enhanced by quality clinical research to provide missing evidence and to refine recommendations, which must be carefully integrated into existing healthcare systems. Realizing a sustainable, global impact on death and suffering due to severe influenza and other severe illness necessitates an ongoing and concerted international effort to iteratively generate, implement, and evaluate best-practice management guidelines for use in resource-limited settings.

Previous research has defined the skills, attitudes and practices that pertain to an ideal clinical educator. However, less attention has been paid to the role of student readiness in terms of foundational knowledge and attitudes at the commencement of practice education. Therefore, the aim of this study was to ascertain clinical educators’ views on the characteristics that they perceive demonstrate that a student is well prepared for clinical learning. Methods A two round on-line Delphi study was conducted. The first questionnaire was emailed to a total of 636 expert clinical educators from the disciplines of occupational therapy, physiotherapy and speech pathology. Expert clinical educators were asked to describe the key characteristics that indicate a student is prepared for a clinical placement and ready to learn. Open-ended responses received from the first round were subject to a thematic analysis and resulted in six themes with 62 characteristics. In the second round, participants were asked to rate each characteristic on a 7 point Likert Scale. Results A total of 258 (40.56% responded to the first round of the Delphi survey while 161 clinical educators completed the second (62.40% retention rate. Consensus was reached on 57 characteristics (six themes using a cut off of greater than 70% positive respondents and an interquartile deviation IQD of equal or less than 1. Conclusions This study identified 57 characteristics (six themes perceived by clinical educators as indicators of a student who is prepared and ready for clinical learning. A list of characteristics relating to behaviours has been compiled and could be provided to students to aid their preparation for clinical learning and to universities to incorporate within curricula. In addition, the list provides a platform for discussions by professional bodies about the role of placement

    Primary immune deficiency diseases (PID) comprise a genetically heterogeneous group of disorders that affect distinct components of the innate and adaptive immune system, such as neutrophils, macrophages, dendritic cells, complement proteins, natural killer cells, as well as T and B lymphocytes. Severe combined immunodeficiency (SCID) is a group of disorders characterized by increased susceptibility to severe infections and early death. The diagnosis of SCID is supported by the demonstration of low absolute lymphocyte count and T cell lymphopenia (variably associated with numerical defects of B and NK cells). In the last two decades, advances in the characterization of the molecular pathophysiology of SCID, have permitted the development of novel diagnostic assays based on analysis of the expression of the disease-associated proteins and mutation analysis. More recently, pilot newborn screening programs for the identification of infants with SCID have been initiated in the United States. Prompt and aggressive treatment of infections, antimicrobial prophylaxis (in particular against Pneumocystis jiroveci) and regular administration of immunoglobulins are essential to reduce the risk of early death. However, survival ultimately depends on reconstitution of immune function, that is usually achieved by means of hematopoietic cell transplantation (HCT). Gene therapy and enzyme replacement therapy have also been used successfully is selected forms of SCID. Here we review the molecular and cellular pathophysiology and the mainstay of treatment of SCID.

    Severe combined immunodeficiency (SCID) is a rare but important condition. Affected infants are born with profound abnormalities of immune cell function that lead to severe and recurrent infection that are almost always fatal in the first year of life without treatment. Infants with SCID are often initially seen by general paediatricians in the hospital care setting, and the recognition of the cardinal features of the disease and alertness to specific laboratory parameters are important in making an early diagnosis. There is also increasing interest in newborn screening for SCID, which has the potential to significantly improve outcome through early diagnosis and implementation of prophylactic medications. Definitive treatments such as haematopoietic stem cell transplantation and gene therapy have also made major advances over the last decade and again promise to improve the overall outcome for SCID with reduced long-term toxicities. In this review, we highlight some of the major advances in diagnosis and management of the disease, but we also want to emphasise the important role of the general paediatrician in making an early diagnosis and in ongoing management.

    ·AIM: To describe the clinical characteristics of Turkish patients with intermediate uveitis(IU) and to investigate the effect of clinical findings and complications on final visual acuity(VA).·METHODS: We retrospectively analyzed the medical records of patients with IU who had at least 6mo of follow-up and were older than 16 y.· RESULTS: A total of 78 eyes of 45 patients were included in the study and the mean follow-up period was19.4mo. The mean age at the time of presentation was42.9s. Systemic disease associations were found in17.7% of cases; sarcoidosis(8.8%) and multiple sclerosis(6.6%) were the most common diseases. Recurrence rate(odds ratio=45.53; 95%CI: 2.181-950.58), vitritis equals to or more than 3+ cells(odds ratio =57.456; 95%CI: 4.154-794.79) and presenting with VA less than 20/40(odds ratio =43.81; 95% CI: 2.184-878.71) were also found as high risk factors for poor final VA. At the last follow-up examination, 67.9% of eyes had VA of 20/40 or better.·CONCLUSION: IU is frequently seen at the beginning of the fourth decade of life. The disease is most commonly idiopathic in adult Turkish patients. Patients with severe vitritis at presentation and patients with frequent recurrences are at high risk for poor visual outcome.

    The aim of this study was to review the epidemiological and clinical characteristics of neuromyelitis optica (NMO) and the immunopathological mechanisms involved in the neuronal damage. NMO is an inflammatory demyelinating autoimmune disease of the central nervous system that most commonly affects the optic nerves and spinal cord. NMO is thought to be more prevalent among non-Caucasians and where multiple sclerosis (MS) prevalence is low. NMO follows a relapsing course in more than 80-90% of cases, which is more commonly in women. It is a complex disease with an interaction between host genetic and environmental factors and the main immunological feature is the presence of anti-aquaporin 4 (AQP4) antibodies in a subset of patients. NMO is frequently associated with multiple other autoantibodies and there is a strong association between NMO with other systemic autoimmune diseases. AQP4-IgG can cause antibody-dependent cellular cytotoxicity (ADCC) when effector cells are present and complement-dependent cytotoxicity (CDC) when complement is present. Acute therapies, including corticosteroids and plasma exchange, are designed to minimize injury and accelerate recovery. Several aspects of NMO pathogenesis remain unclear. More advances in the understanding of NMO disease mechanisms are needed in order to identify more specific biomarkers to NMO diagnosis.

    Full Text Available Objective. 312 tinnitus sufferers were studied in order to analyze: the clinical characteristics of tinnitus; the presence of tinnitus-age correlation and tinnitus-hearing loss correlation; the impact of tinnitus on subjects' life and where possible the etiological/predisposing factors of tinnitus. Results. There is a slight predominance of males. The highest percentage of tinnitus results in the decades 61–70. Of the tinnitus sufferers, 197 (63.14% have a hearing deficit (light hearing loss in 37.18% of cases. The hearing impairment results of sensorineural type in 74.62% and limited to the high frequencies in 58.50%. The tinnitus is referred as unilateral in 59.93%, a pure tone in 66.99% and 10 dB above the hearing threshold in 37.7%. It is limited to high frequencies in 72.10% of the patients with sensorineural hearing loss (SNHL while the 88.37% of the patients with high-frequency SNHL have a high-pitched tinnitus (2=66.26;<.005. Conclusion. Hearing status and age represent the principal tinnitus related factors; there is a statistically significant association between high-pitched tinnitus and high-frequency SNHL. There is no significant correlation between tinnitus severity and tinnitus loudness confirming the possibility that neural connection involved in evoking tinnitus-related negative reactions are governed by conditioned reflexes.

    Results: Crush injury of leg with fracture of tibia and fibula was observed in 78% of injured limbs. The most common mechanism of injury was high-energy trauma. Road traffic accidents accounted for 72% of patients. Mean hospitalization for primary amputation was 19.3 (8-26 days and for delayed amputation limbs was 36.6 (15-62 days and for salvaged limbs was 45.5 (14-128 days. In the prospective study, out of 7 injured limbs with a MESS score of equal or more than 7, 6 limbs were amputated and 1 limb was salvaged. Out of the remaining 18 injured limbs with a MESS score of less than 7, 17 limbs were successfully salvaged and one limb was amputated. In the retrospective study, 10 injured limbs with a MESS score of equal or more than 7 were amputated (mean score 8.4 with range of 10-8 and the remaining 15 injured limbs with a MESS score of less than 7 were salvaged (mean score 4.57 with range of (4-6; suggesting a significant difference in the mean scores. Conclusions: MESS is a cost-effective, relatively simple and readily available scoring system, which assists the surgeon to identify variables that may ultimately influence the outcome of a severely traumatized extremity with arterial compromise due to high-energy injury.

    Yacovino, Dario A; Hain, Timothy C

    2013-07-01

    Cervical vertigo has long been a controversial entity and its very existence as a medical entity has advocates and opponents. Supporters of cervical vertigo claim that its actual prevalence is underestimated due to the overestimation of other diagnostic categories in clinics. Furthermore, different pathophysiological mechanisms have been attributed to cervical vertigo. Here the authors discuss the clinical characteristics of rotational vertebral artery vertigo, postwhiplash vertigo, proprioceptive cervical vertigo, and cervicogenic vertigo of old age. A clinical entity named subclinical vertebrobasilar insufficiency appears in the context of cervical osteoarticular changes. Migraine-associated vertigo may explain why some patients suffering from cervical pain have vertigo while others do not.

    Objective The objectives of this study were to describe the clinical characteristics and outcomes of poisoning by zinc phosphide, a common rodenticide in Thailand, and to evaluate whether these outcomes can be prognosticated by the clinical presentation. Materials and methods A 3-year retrospective cohort study was performed using data from the Ramathibodi Poison Center Toxic Exposure Surveillance System. Results In total, 455 poisonings were identified. Most were males (60.5%) and from the central region of Thailand (71.0%). The mean age was 39.91±19.15 years. The most common route of exposure was oral (99.3%). Most patients showed normal vital signs, oxygen saturation, and consciousness at the first presentation. The three most common clinical presentations were gastrointestinal (GI; 68.8%), cardiovascular (22.0%), and respiratory (13.8%) signs and symptoms. Most patients had normal blood chemistry laboratory results and chest X-ray findings at presentation. The median hospital stay was 2 days, and the mortality rate was 7%. Approximately 70% of patients underwent GI decontamination, including gastric lavage and a single dose of activated charcoal. In all, 31 patients were intubated and required ventilator support. Inotropic drugs were given to 4.2% of patients. Four moribund patients also received hyperinsulinemia–euglycemia therapy and intravenous hydrocortisone; however, all died. Patients who survived and died showed significant differences in age, duration from taking zinc phosphide to hospital presentation, abnormal vital signs at presentation (tachycardia, low blood pressure, and tachypnea), acidosis, hypernatremia, hyperkalemia, in-hospital acute kidney injury, in-hospital hypoglycemia, endotracheal tube intubation, and inotropic requirement during hospitalization (P<0.05). Conclusion Zinc phosphide poisoning causes fatalities. Most patients have mild symptoms, and GI symptoms are the most common. Patients who present with abnormal vital signs or

    Background Despite the notoriety of Ebola virus disease (EVD) as one of the world’s most deadly infections, EVD has a wide range of outcomes, where asymptomatic infection may be almost as common as fatality. With increasingly sensitive EVD diagnosis, there is a need for more accurate prognostic tools that objectively stratify clinical severity to better allocate limited resources and identify those most in need of intensive treatment. Methods/Principal Findings This retrospective cohort study analyses the clinical characteristics of 158 EVD(+) patients at the GOAL-Mathaska Ebola Treatment Centre, Sierra Leone. The prognostic potential of each characteristic was assessed and incorporated into a statistically weighted disease score. The mortality rate among EVD(+) patients was 60.8% and highest in those aged 25 years (pEbola viral load (p = 0.1), potentially indicating a pathologic synergy between the infections. Similarly, referral-time interacted with viral load, and adjustment revealed referral-time as a significant determinant of mortality, thus quantifying the benefits of early reporting as a 12% mortality risk reduction per day (p = 0.012). Disorientation was the strongest unadjusted predictor of death (OR = 13.1, p = 0.014) followed by hiccups, diarrhoea, conjunctivitis, dyspnoea and myalgia. Including these characteristics in multivariate prognostic scores, we obtained a 91% and 97% ability to discriminate death at or after triage respectively (area under ROC curve). Conclusions/Significance This study proposes highly predictive and easy-to-use prognostic tools, which stratify the risk of EVD mortality at or after EVD triage. PMID:28151955

    More men than women are diagnosed with Parkinson's disease (PD), and a number of gender differences have been documented in this disorder. Examples of clinical characteristics that appear in men more often than women include rigidity and rapid eye movement behavior disorder, whereas more women than men exhibit dyskinesias and depression. Differences between men and women in cognition have not been extensively examined, though there are reports of deficits in men in aspects of cognition that contribute to activities of daily living, in verbal fluency, and in the recognition of facial emotion, and deficits in women in visuospatial cognition. Side of disease onset may interact with gender to affect cognitive abilities. One possible source of male-female differences in the clinical and cognitive characteristics of PD is the effect of estrogen on dopaminergic neurons and pathways in the brain. This effect is not yet understood, as insight into how the fluctuation of estrogen over the lifetime affects the brain is currently limited. Further attention to this area of research will be important for accurate assessment and better management of PD. Attention should also be directed to multiple covariates that may affect clinical characteristics and cognition. Knowledge about differences in the presentation of PD symptoms in men and women and about the pathophysiology underlying those differences may enhance the accuracy and effectiveness of clinical assessment and treatment of the disease.

    clinical characteristics of two groups were comparable. Left ventricular end diastolic diameter (LVEDd) of group A was larger than group B [ (70. 56 ± 4. 33 ) mm vs. ( 63.73 ± 3.75 ) mm, P < 0. 05 ], the left ventricular ejection fraction (LVEF) of group A was lower than group B [ (24. 16 ± 2. 50) % vs. (28.49 ± 2.63 ) %, P < 0. 05 ]. The number of patents tolerating metoprolol in group A is lower than in group B (7/13 vs. 39/44,P <0. 05),and the tolerant dose of metoprolol in group A is lower than in group B [ ( 12. 5 ±6. 25)mg/d vs. (24. 20 ±11.22)mg/d,P < 0. 05 ]. The level of BNP in group B were significantly higher at acute stages than at remission stages [(962.73 ± 165.00) ng/L vs. (876.24 ± 167.70) ng/L, P < 0.05], but remained unchanged in group A [ (74. 03 ± 11.18) ng/L vs. ( 71.38 ± 11.68) ng/L, P > 0. 05 ]. The mortality of group A was higher than group B( 11/12 vs. 6/44, P <0.05). The binary logistic regression analysis (backward) showed that normal B-type natriuretic peptide was an independent predictor of cardiovascular mortality in patients with severe chronic heart failure ( OR = 45.488, 95% CI = 5. 322 - 388. 791 ).Conclusion Normal BNP in patients with severe chronic heart failure suggests the exhaustion of BNP secretion and associated poor prognosis.

Methods: We conducted a retrospective analysis of medical charts data of all diabetic inpatients of the Endocrine and Diabetes Unit of Walter Cantídio University Hospital (Federal University of Ceará, admitted from January, 2006 to June, 2007 for severe foot ulcers (minimum of grade 2 of Wagner`s classification, which were refractory to ambulatory treatment. Clinical data from each patient were recorded (sex, age, diabetes duration, and comorbidities as well as microbiological characteristics of foot ulcers and surgical (amputations material. Results: We identified 17 diabetic patients, all type 2, aged 58.11 ± 10.8 years and 12.4 ± 8.4 years of disease, 58.8% male. Of ulcers, 41.1% were grade 2; 35.2% grade 3; 11.7% grade 4 and 11.7% grade 5 of Wagner; 64.7% with less than 3 months of evolution. Debridement was performed in 82.3% of patients and amputation in 47%; osteomyelitis was identified in 47% of cases. All patients started empiric antibiotic therapy, where ciprofloxacin/metronidazole was the most used scheme (76.5%. Cultures were negative in 12.5% of the patients. In the positive ones, the most prevalent bacterial pathogens detected in the culture materials were: S. aureus (57.1%; S. viridans (28.7%; P. aeruginosas (28.7%; M. morganii (28.7%. The majority (75% of isolated S. aureus were methicillin-resistant, but were sensitive to vacomicin. Conclusion: We observed the presence of polymicrobial flora with a large number of multiresistant pathogens and high prevalence of osteomyelitis and amputations in diabetic patients with severe ulcers, neuropathy and peripheral vascular disease.

    Full Text Available Abstract Background Severe acute respiratory syndrome (SARS, a recent epidemic human disease, is caused by a novel coronavirus (SARS-CoV. First reported in Asia, SARS quickly spread worldwide through international travelling. As of July 2003, the World Health Organization reported a total of 8,437 people afflicted with SARS with a 9.6% mortality rate. Although immunopathological damages may account for the severity of respiratory distress, little is known about how the genome-wide gene expression of the host changes under the attack of SARS-CoV. Results Based on changes in gene expression of peripheral blood, we identified 52 signature genes that accurately discriminated acute SARS patients from non-SARS controls. While a general suppression of gene expression predominated in SARS-infected blood, several genes including those involved in innate immunity, such as defensins and eosinophil-derived neurotoxin, were upregulated. Instead of employing clustering methods, we ranked the severity of recovering SARS patients by generalized associate plots (GAP according to the expression profiles of 52 signature genes. Through this method, we discovered a smooth transition pattern of severity from normal controls to acute SARS patients. The rank of SARS severity was significantly correlated with the recovery period (in days and with the clinical pulmonary infection score. Conclusion The use of the GAP approach has proved useful in analyzing the complexity and continuity of biological systems. The severity rank derived from the global expression profile of significantly regulated genes in patients may be useful for further elucidating the pathophysiology of their disease.

    To determine whether the presence of melancholic features in hospitalized patients with major depressive disorder (MDD) was associated with specific clinical characteristics and treatment outcomes, supporting melancholic depression as a distinct subtype within MDD. 126 acutely ill inpatients with MDD were enrolled in an open, 6-week trial with fixed-dose fluoxetine 20mg daily. Symptom severity was assessed regularly, using the 17-item Hamilton Depression Rating Scale (HAMD-17) and Clinical Global Impression of Severity (CGI-S). Melancholic features were defined according to the DSM-IV criteria. Clinical variables were compared between patients with and without melancholic features. Generalized estimating equations method was used to explore the differences in HAMD-17 and CGI-S scores between the 2 groups over time. Clinical response was defined as having a 50% or greater reduction in HAMD-17 scores. 96 (76.2%) of the 126 patients with at least one post-baseline assessment met the criteria for melancholic depression. Melancholic depression differed from non-melancholic depression in clinical characteristics and predicted a better response to fluoxetine treatment. The differentiation between melancholic and non-melancholic depression within MDD hence is clinically significant and valid.

    The clinical implications of thyroid hormones in depression have been studied extensively and still remains disputable. Supplementation of thyroid hormones is considered to augment and accelerate antidepressant treatment. Studies on the role of thyroid hormones in depression deliver contradictory results. Here we assess theirs impact on depression severity and final clinical outcome in patients with major depression. Thyrotropin, free thyroxine (FT4), and free triiodothyronine (FT3) concentrations were measured with automated quantitative enzyme immunoassay. Depression severity and final clinical outcome were rated with 17-itemic Hamilton Rating Scale for Depression [HDRS(17)] and Clinical Global Impression Scales for severity and for improvement (CGIs, CGIi). FT3 and FT4 concentrations were significantly positively correlated with clinical improvement evaluated with CGIi (R = 0.38, P = 0.012; R = 0.33, P = 0.034, respectively). There was a significant correlation between FT4 concentrations and depression severity assessed in HDRS(17) (R = 0.31, P = 0.047). Male patients presented significantly higher FT3 serum levels (Z = 2.34, P = 0.018) and significantly greater clinical improvement (Z = 2.36, P = 0.018) when compared to female patients. We conclude that free thyroid hormones concentrations are associated with depression severity and have an impact on final clinical outcome. It can be more efficient to augment and accelerate the treatment of major depressive disorder with triiodothyronine instead of levothyroxine because of individual differences in thyroid hormones metabolism.

    Liver cancer is an aggressive malignant disease with a poor prognosis. Patients with liver cancer are usually diagnosed at an advanced stage and thus miss the opportunity for surgical resection. Chemotherapy and radiofrequency ablation, which target tumor bulk, have exhibited limited therapeutic efficacy to date. Liver cancer stem cells (CSCs) are a small subset of undifferentiated cells existed in liver cancer, which are considered to be responsible for liver cancer initiation, metastasis, relapse and chemoresistance. Elucidating liver CSC characteristics and disclosing their regulatory mechanism might not only deepen our understanding of the pathogenesis of liver cancer but also facilitate the development of diagnostic, prognostic and therapeutic approaches to improve the clinical management of liver cancer. In this review, we will summarize the recent advances in liver CSC research in terms of the origin, identification, regulation and clinical correlation.

    At the beginning of the swine influenza (H1N1) pandemic in the spring of 2009, there were still stories of human seasonal influenza A circulating in the New York area. Adult patients admitted with influenza-like illnesses (ILIs) (fever > 102°F, dry cough, and myalgias) presented diagnostic problems. First, clinicians had to differentiate ILIs from influenza, and then differentiate human seasonal influenza A from H1N1 in hospitalized adults with ILIs and negative chest films (no focal segmental/lobar infiltrates). Human seasonal influenza A was diagnosed by rapid influenza diagnostic tests (RIDTs), but H1N1 was often RIDT negative. Reverse transcriptase-polymerase chain reaction for H1N1 was restricted or not available. The Winthrop-University Hospital Infectious Disease Division developed clinical diagnostic criteria (a diagnostic weighted point score system) to rapidly and clinically diagnose H1N1 in patients with negative RIDTs. The point score system was modified and shortened for ease of use, that is, the diagnostic H1N1 triad (any 3 of 4) (ILI, see above) plus thrombocytopenia, relative lymphopenia, elevated serum transaminases, or an elevated creatine phosphokinase. Our clinical experience during the pandemic allowed us to develop the swine diagnostic H1N1 triad. In the process, similarities and differences between human seasonal influenza A and H1N1 were noted. We present 2 illustrative cases of severe influenza, one due to human seasonal influenza A and one due to H1N1, for clinical consideration reflective of our experiences early in the H1N1 pandemic in 2009.

    Full Text Available INTRODUCTION: Persistent postural-perceptual dizziness is the dizziness that lasts for over three months with no clinical explanation for its persistence. The patient's motor response pattern presents changes and most patients manifest significant anxiety. OBJECTIVE: To evaluate the clinical characteristics of patients with persistent postural and perceptual dizziness. METHODS: statistical analysis of clinical aspects of patients with persistent postural-perceptual dizziness. RESULTS: 81 patients, average age: 50.06 ± 12.16 years; female/male ratio: 5.7/1; main reasons for dizziness: visual stimuli (74%, body movements (52%, and sleep deprivation (38%. The most prevalent comorbidities were hypercholesterolemia (31%, migraine headaches (26%, carbohydrate metabolism disorders (22% and cervical syndrome (21%. DHI, State-Trait Anxiety Inventory - Trait, Beck Depression Inventory, and Hospital Anxiety and Depression Scale questionnaires were statistically different (p < 0.05 when compared to controls. 68% demonstrated clinical improvement after treatment with serotonin reuptake inhibitors. CONCLUSION: Persistent postural-perceptual dizziness affects more women than men, with a high associated prevalence of metabolic disorders and migraine. Questionnaires help to identify the predisposition to persistent postural-perceptual dizziness. The prognosis is good with adequate treatment.

    Abstract A retrospective cross-sectional study using data from an outpatient clinic in China was conducted to investigate the clinical features of early-onset gout patients. All patients diagnosed with gout were asked about clinical characteristics of their gout and comorbid diseases. Patients presenting with acute flares were asked about common triggers before the flare. “Early-onset” gout was defined as onset of gout before 40 years and “late-onset” as onset ≥40 years. Major joint involvement, flare frequency before presentation, the cumulative number of involved joints, proportions of tophi complications at presentation, flare triggers, as well as any metabolic, cardiovascular, cerebrovascular, and renal comorbidities, were compared between the 2 groups. A total of 778 gout patients were enrolled in this study, including 449 (57.7%) in the early-onset group and 329 (42.3%) in the late-onset group. Compared with the late-onset gout patients, the early-onset gout patients had a higher proportion of ankle/mid-foot involvement (62.8% vs 48.2%, P gout patients had fewer metabolic, cardiovascular, cerebrovascular, or renal complications. Early- and late-onset gout patients had different clinical features. Early-onset seems to be influenced more by lifestyle, while late-onset patients have more complications because of comorbidities.

    Full Text Available Background and Design: The purpose of this study was to obtain data that may provide an insight into the etiopathogenesis of recurrent aphtous stomatitis (RAS by the way of analysing the sociodemographic and clinical characteristics of patients who had been diagnosed with RAS. Materials and Metods: The patients, who were diagnosed with RAS in the dermatology outpatient clinic, between May 2007 and May 2010, were evaluated retrospectively. The data including sociodemografic and clinical characteristics, and treatment options were recorded. Results: A hundred patients (68 women, 32 men were included in this study. The average age was 40±13.6 years. RAS was more common in patients with middle-income and low education. The most common type of RAS was minor aphtous ulcers (88%. The lesions were most frequently seen on the lateral side of the tongue (34% and cheek (34%. Sixty percent of patients had a positive family history. Some factors such as biting (12%, tooth brushing (18%, dental disease presence (82%, food (39%, menstruation (10.3%, stress (76%, iron deficiency (16.7%, vitamin B12 deficiency (22.4%, low serum ferritin levels (18%, and seasonal variability (32% showed positive correlation with RAS. A negative correlation was found between RAS and smoking. Forty-nine percent of patients had used alternative therapies in addition to drug therapy. The most frequently used alternative method was consumption of sumac (26.5%. Conlucions: In contrast to the literature, our study found that RAS is started in the third decade of life and, approximately 50% of patients prefered alternative treatment methods, particularly sumac. Nowadays, discussions about the etiopathogenesis of RAS continue. In this study, we found that different sociodemographic and clinical factors may be associated with the etiopathogenesis of the disease. Our study will be followed by further studies using prospective design to identify the the etiopathogenesis of RAS.

    Full Text Available The aim of the presented paper is a meta-analysis of clinical studies on the comparative effectiveness of pharmaceutical therapy and surgical treatment such as cardiac resynchronization therapy (CRT, cardiac resynchronization therapy with cardioversion-defibrillation (CRT-D, circulatory support system and heart transplantation in patients with severe chronic heart failure (CHF. Material and Methods. Results of 41 clinical studies (29799 patients with severe CHF were included in a meta-analysis. Data search was conducted in the following databases: Medline, Medscape, Pubmed, and websites dedicated to clinical research (National Institutes of Health, Clinical Center, ClinicalStudyResults.org, ClinicalTrials.gov. Results. As compared with pharmaceutical therapy, surgical treatment of severe CHF is better to reduce fatal risk, incidence of decompensation of CHF, frequency of cardiac arrhythmias, the need to perform or re-perform heart transplantation. It is also shown that CRT better reduced the mortality from progression of heart failure than heart transplantation. Both pharmaceutical therapy and surgical treatment improved functional class of CHF and quality of patients' life, but does not affect the left ventricular ejection fraction. Conclusion. It was found out that there was a number of significant advantages of surgical treatment of severe CHF, compared with pharmaceutical therapy. However, it is still a number of unresolved issues (particularly in relation to heart transplantation on the effectiveness comparing pharmaceutical and surgical therapies of severe CHF

    Full Text Available Introduction: Kikuchi-Fujimoto disease is an uncommon disorder with worldwide distribution, characterized by fever and benign enlargement of the lymph nodes, primarily affecting young adults. Awareness about this disorder may help prevent misdiagnosis and inappropriate investigations and treatment. The objective of the study was to evaluate the clinical and laboratory characteristics of histopathologically confirmed cases of Kikuchi′s disease from a tertiary care center in southern India. Materials and Methods: Retrospective analysis of all adult patients with histopathologically confirmed Kikuchi′s disease from January 2007 to December 2011 in a 2700-bed teaching hospital in South India was done. The clinical and laboratory characteristics and outcome were analyzed. Results: There were 22 histopathologically confirmed cases of Kikuchi′s disease over the 5-year period of this study. The mean age of the subjects′ was 29.7 years (SD 8.11 and majority were women (Male: female- 1:3.4. Apart from enlarged cervical lymph nodes, prolonged fever was the most common presenting complaint (77.3%. The major laboratory features included anemia (54.5%, increased erythrocyte sedimentation rate (31.8%, elevated alanine aminotransferase (27.2% and elevated lactate dehydrogenase (LDH (31.8%. Conclusion: Even though rare, Kikuchi′s disease should be considered in the differential diagnosis of young individuals, especially women, presenting with lymphadenopathy and prolonged fever. Establishing the diagnosis histopathologically is essential to avoid inappropriate investigations and therapy.

    [Purpose] To describe the clinical characteristics affecting motor recovery and ambulation in stroke patients. [Subjects and Methods] Demographic and clinical characteristics of 53 stroke patients (31 M, 22 F), such as age, gender, etiology, hemiplegic side, Brunnstrom stage, functional ambulation scale scores, history of rehabilitation, and presence of shoulder pain and complex regional pain syndrome were evaluated. [Results] The etiology was ischemic in 79.2% of patients and hemorrhagic in 20.8%. Brunnstrom hand and upper extremity values in females were lower than in males. Complex regional pain syndrome was observed at a level of 18.9% in all patients (more common in females). Brunnstrom hand stage was lower in complex regional pain syndrome patients than in those without the syndrome. Shoulder pain was present in 44.4% of patients. Brunnstrom lower extremity values and functional ambulation scale scores were higher in rehabilitated than in non-rehabilitated cases. [Conclusion] Brunnstrom stages of hand and upper extremity were lower and complex regional pain syndrome was more common in female stroke patients. Shoulder pain and lower Brunnstrom hand stages were related to the presence of complex regional pain syndrome. PMID:28265142

    Severely resorbed mandibles with placed endosteal dental implants can fracture. Therefore, techniques to reduce the risk or minimize the consequences of these fractures are needed. This clinical report presents a technique for placing a titanium plate in a severely resorbed mandible subjected to complete-arch implant therapy. The titanium plate is placed in the same surgical procedure as the implants, allowing immediate implant loading. This technique provides safe implant-supported treatment for patients with severe mandibular resorption.

    Full Text Available Aim: the aim of the study is to evaluate the socio-demographic and clinical features with prognostic value in predicting evolution in severe OCD.Materials and methods: patients with a main diagnosis of OCD were recruited according to DSM-IV criteria. Socio-demographic and clinical features were assessed by mean of a semi-structured interview and clinical rating scales (Y-BOCS, HAM-A, HAM-D and SCID-II. Two subgroups were compared according to the severity of symptoms (severe vs mild-moderate.Results: the total sample was made up of 450 OCD subjects aged 34.5±12.1, with a mean age of onset 22.3±9.1; 215 subjects (47.8% were females. Patients with severe OCD (Y-BOCS ≥ 32 showed a more insidious onset and a more chronic course compared to patients with mild-moderate symptoms. Other predictors of increased OCD severity were washing and hoarding compulsions. Lastly, the severity of the obsessive-compulsive condition was higher when it was associated either with mood disorders or with Axis II disorders (particularly Cluster A.Discussion: our study shows a correlation between severe OCD and severity predictors such as functional impairment and mood disorders. Furthermore washing and hoarding symptoms, lifetime comorbity with mood disorders and Cluster A personality disorders seem to predict OCD severity.

    Full Text Available We aimed to develop and validate a risk score to aid in the early identification of laboratory-confirmed dengue patients at high risk of severe dengue (SD (i.e. severe plasma leakage with shock or respiratory distress, or severe bleeding or organ impairment. We retrospectively analyzed data of 1184 non-SD patients at hospital presentation and 69 SD patients before SD onset. We fit a logistic regression model using 85% of the population and converted the model coefficients to a numeric risk score. Subsequently, we validated the score using the remaining 15% of patients. Using the derivation cohort, two scoring algorithms for predicting SD were developed: models 1 (dengue illness ≤4 days and 2 (dengue illness >4 days. In model 1, we identified four variables: age ≥65 years, minor gastrointestinal bleeding, leukocytosis, and platelet count ≥100×109 cells/L. Model 1 (ranging from -2 to +6 points showed good discrimination between SD and non-SD, with an area under the receiver operating characteristic curve (AUC of 0.848 (95% confidence interval [CI], 0.771-0.924. The optimal cutoff value for model 1 was 1 point, with a sensitivity and specificity for predicting SD of 70.3% and 90.6%, respectively. In model 2 (ranging from 0 to +3 points, significant predictors were age ≥65 years and leukocytosis. Model 2 showed an AUC of 0.859 (95% CI, 0.756-0.963, with an optimal cutoff value of 1 point (sensitivity, 80.3%; specificity, 85.8%. The median interval from hospital presentation to SD was 1 day. This finding underscores the importance of close monitoring, timely resuscitation of shock including intravenous fluid adjustment and early correction of dengue-related complications to prevent the progressive dengue severity. In the validation data, AUCs of 0.904 (95% CI, 0.825-0.983 and 0.917 (95% CI, 0.833-1.0 in models 1 and 2, respectively, were achieved. The observed SD rates (in both cohorts were 50% for those with a score of ≥2 points

    Full Text Available Background: Takotsubo cardiomyopathy (TC or transient left ventricular apical ballooning syndrome is an acute cardiac syndrome characterized by transient wall motion abnormalities extending beyond a single epicardial vessel in the absence of significant obstructive coronary artery disease. Aim: This study was to describe the clinical characteristics of TC in North America. Materials and Methods: We identified 10 patients who met the Mayo Clinic criteria for TC using our Electronic Medical Records. We also conducted a systematic review of case series of TC that were done in North America by searching the MEDLINE database. We identified 11 case series that met our eligibility criteria. Results: Our systematic review included 620 patients. Chest pain and ST segment elevation were the cardinal features of this syndrome, but the prevalence was lower than in the European and Asian cohort (50% and 39% as compared with 80% and 70%, respectively. Classic precipitating emotional or physical stress was described in > 80% of patients. Cardiac biomarkers were found to be elevated in >90% of our patients. Conclusions : TC is a worldwide problem and clinical presentation appears to be similar in North American, European, and Asian countries. However, fewer patients in our cohort presented with typical chest pain and electrocardiography (ECG changes, which might suggest ethnic variations in the syndrome or perhaps a more aggressive diagnostic approach in North American countries.

    Background Respiratory distress syndrome (RDS) is one of the most common causes of neonatal respiratory failure and neonatal death, however, its clinical characteristics are very different from premature RDS, and these characteristics have not been well documented as yet. This study was to investigate the pathogenesis, clinical characteristics and management strategies of RDS in full-term neonates, with the aim of developing a working protocol for improving the outcome in full-term neonates with RDS.Methods A total of 125 full-term infants with RDS were enrolled in this study. Their clinical and laboratory data were collected for analyzing the characteristics of full-term neonatal RDS.Results (1) The 125 cases included 94 male and 31 female infants, vaginal delivery occurred in 80 cases and cesarean section in 45 cases. (2) The onset time of RDS was (3.11±3.59) hours after birth. (3)The possible reasons included severe perinatal infections in 63 patients, elective cesarean section in 34 cases, severe birth asphyxia in 12 patients,meconium aspiration syndrome in 9 patients, pulmonary hemorrhage in 4 patients and matemal diabetes in 3 patients. (4)Complications included multiple organ system failure (MOSF) in 49 patients, persistent pulmonary hypertension of newborn (PPHN) in 25 patients, acute renal failure in 18 patients, severe hyperkalemia in 25 patients, severe metabolic acidosis in 6 cases, severe myocardial injury in 9 cases, pulmonary hemorrhage in 3 cases, disseminated intravascular coagulation in 14 patients and shock in 12 patients.(5) Four patients died, the mortality was therefore 3.2% with the main cause of septicemia complicating of MOSF, but their prognosis was improved while comprehensive treatment measures including early mechanical ventilation and broad spectrum antibiotics were taken into account.Conclusions RDS is not an uncommon disease in full-term infants and is associated with a higher mortality, its clinical characteristics are very

    Schizophrenia (SCH) is a complex, psychiatric disorder affecting 1 % of population. Its clinical phenotype is heterogeneous with delusions, hallucinations, depression, disorganized behaviour and negative symptoms. Bipolar affective disorder (BD) refers to periodic changes in mood and activity from depression to mania. It affects 0.5-1.5 % of population. Two types of disorder (type I and type II) are distinguished by severity of mania episodes. In our analysis, we aimed to check if clinical and demographical characteristics of the sample are predictors of symptom dimensions occurrence in BD and SCH cases. We included total sample of 443 bipolar and 439 schizophrenia patients. Diagnosis was based on DSM-IV criteria using Structured Clinical Interview for DSM-IV. We applied regression models to analyse associations between clinical and demographical traits from OPCRIT and symptom dimensions. We used previously computed dimensions of schizophrenia and bipolar affective disorder as quantitative traits for regression models. Male gender seemed protective factor for depression dimension in schizophrenia and bipolar disorder sample. Presence of definite psychosocial stressor prior disease seemed risk factor for depressive and suicidal domain in BD and SCH. OPCRIT items describing premorbid functioning seemed related with depression, positive and disorganised dimensions in schizophrenia and psychotic in BD. We proved clinical and demographical characteristics of the sample are predictors of symptom dimensions of schizophrenia and bipolar disorder. We also saw relation between clinical dimensions and course of disorder and impairment during disorder.

    Full Text Available BACKGROUND : Perforator incompetence is an important part of assessment of chronic venous insufficiency ( CVI, but the criteria for perforator incompetence and the relationship with clinical severity is not well established. AIM: To study whether measurement of diameter of perforator correlates with clinical severity of venous insufficiency. MATERIALS AND METHODS: One hundred and forty five consecutive patients ( 168 limbs with varicose veins were evaluated with Doppler study of lower limb veins. Clinical severity and diameter of perforators were assessed. RESULTS: 23% of patients with clinically mild disease had perforator diameter of 3mm or more , whereas , 62% of moderate and severe disease patients had incompetent perforator. Average diameter of perforator in CVI class 1 & 2 patients was 1.44mm whereas , in class 3 & 4 patients , it was 3.31mm and 3.58mm in class 5 & 6 patients. CONCLUSION : Diameter of perforator compare favourably with clinical severity of chronic venous insufficiency. This study may help to evolve patient management guidelines in perforator incompetence treatment

    Full Text Available Ulcerative colitis (UC is a chronic inflammation of the coli mucosa clinically characterized by bloody diarrhea, abdominal pain and other systemic symptoms. The onset, as well as subsequent relapses, may occur with varying degrees of clinical and endoscopic activity and extent of disease. The clinical and endoscopic activity varies from mild to severe, while the extent of disease, without interruption, may involve from the rectum up to the entire colon. The severe form, when not properly and promptly treated, can be life-threatening and may determine various complications requiring urgent surgical treatment. Early recognition of severe forms, their treatment and patient monitoring can reduce morbidity and mortality, and improve surgical outcome. Since the 1950s, systemic corticosteroids have been the first-line treatment in severe active UC. Today, appropriate patient monitoring, and recognition of clinical, radiological and laboratory findings indicative of steroid failure guide the clinician in the use of immunomodulatory drugs or suggest indications for surgery. The aim of our study is to review the more recent data and guidelines that could be useful in clinical practice for the management of severe UC.

    Severe pneumonia in children under 5 years of age continues to be an important clinical entity with treatment failure rates as high as 20%. Where severe pneumonias are common, predictive tools for treatment failure like chest radiography and pulse oximetry are not available or affordable. Thus, there is a need for development of simple, accurate and inexpensive clinical tools for prediction of treatment failure. Using clinical, chest radiographic and pulse oximetry data from 1702 children recruited in the Amoxicillin Penicillin Pneumonia International Study (APPIS) trial we developed and validated a simple clinical tool. For development, a randomly derived development sample (n = 889) was used. The tool which was based on the results of multivariate logistic regression models was validated on a separate sample of 813 children. The derived clinical tool in its final form contained three clinical predictors: age of child, excess age-specific respiratory rate at baseline and at 24 hr of hospitalization. This tool had a 70% and 66% predictive accuracy in the development and validation samples, respectively. The tool is presented as an easy-to-use nomogram. It is possible to predict the likelihood of treatment failure in children with severe pneumonia based on clinical features that are simple and inexpensive to measure.

    Hemifacial spasm (HFS) is a common neurological disorder characterized by involuntary tonic and clonic contractions of the muscles innervated by the facial nerve. We aimed to describe clinical features, common antecedents, triggers and relieving factors in patients with hemifacial spasm to study the correlation of hypertension and HFS, and to compare clinical features of primary and secondary cases of HFS. The data for the study were collected prospectively on a predesigned and pre-tested format at the first attendance in all consecutive HFS patients attending the movement disorders clinic of a tertiary teaching hospital in India. The demographic profile, HFS symptoms, antecedent illnesses and neurological examination were recorded and analyzed. Muscle power in individual muscles innervated by the facial nerve was tested carefully before botulinum toxin injection. Hemifacial spasm occurred in 7.14% (n = 582) of 8,151 cases registered at the movement disorders clinic from 1993 to 2010. Data of 321 patients were complete and were included in the study. Females constituted 49.22% (n = 158). The mean age the patients was 46.02 ± 11.82 years; ipsilateral ear clicking was observed in 22.74% cases. The most common aggravating factor was stress (44.86%), while the most common relieving factor was sleep (44.24%). Two hundred fifty-two patients (78.5%) had primary HFS. The severity of spasm correlated significantly with disease duration (p muscles (p < 0.001). We did not observe any correlation between HFS on the left side and hypertension, as has been reported earlier. This is one of the largest studies of HFS patients and the only one that prospectively assesses patients with HFS clinically on their first visit. Interesting observations of this study are lack of female preponderance, presence of clicking in the ipsilateral ear and facial weakness even prior to botulinum toxin injection.

    Full Text Available Recently, there has been a problem of shortage of sleep laboratories that can accommodate the patients in a timely manner. Delayed diagnosis and treatment may lead to worse outcomes particularly in patients with severe obstructive sleep apnea (OSA. For this reason, the prioritization in polysomnography (PSG queueing should be endorsed based on disease severity. To date, there have been conflicting data whether clinical information can predict OSA severity. The 1,042 suspected OSA patients underwent diagnostic PSG study at Siriraj Sleep Center during 2010-2011. A total of 113 variables were obtained from sleep questionnaires and anthropometric measurements. The 19 groups of clinical risk factors consisting of 42 variables were categorized into each OSA severity. This study aimed to array these factors by employing Fuzzy Analytic Hierarchy Process approach based on normalized weight vector. The results revealed that the first rank of clinical risk factors in Severe, Moderate, Mild, and No OSA was nighttime symptoms. The overall sensitivity/specificity of the approach to these groups was 92.32%/91.76%, 89.52%/88.18%, 91.08%/84.58%, and 96.49%/81.23%, respectively. We propose that the urgent PSG appointment should include clinical risk factors of Severe OSA group. In addition, the screening for Mild from No OSA patients in sleep center setting using symptoms during sleep is also recommended (sensitivity = 87.12% and specificity = 72.22%.

    Full Text Available Abstract Background Anaemia is the most common haematological complication of HIV and associated with a high morbidity and a poor prognosis. The pathogenesis of HIV-associated anaemia is poorly understood and may include a direct effect of HIV on erythropoiesis. In vitro studies have suggested that specific HIV strains, like X4 that uses the CXCR4 co-receptor present on erythroid precursors, are associated with diminished erythropoiesis. This co-receptor affinity is determined by changes in the hypervariable loop of the HIV-1 envelope genome. In a previous case-control study we observed an association between HIV and severe anaemia in Malawian children that could not be fully explained by secondary infections and micronutrient deficiencies alone. We therefore explored the possibility that alterations in the V1-V2-V3 fragment of HIV-1 were associated with severe anaemia. Methods Using peripheral blood nucleic acid isolates of HIV-infected children identified in the previous studied we assessed if variability of the V1-V2-V3 region of HIV and the occurrence of X4 strains were more common in HIV-infected children with (cases, n = 29 and without severe anaemia (controls, n = 30. For 15 cases bone marrow isolates were available to compare against peripheral blood. All children were followed for 18 months after recruitment. Results Phylogenetic analysis showed that HIV-1 subtype C was present in all but one child. All V1-V2-V3 characteristics tested: V3 charge, V1-V2 length and potential glycosylation sites, were not found to be different between cases and controls. Using a computer model (C-PSSM four children (7.8% were identified to have an X4 strain. This prevalence was not different between study groups (p = 1.00. The V3 loop characteristics for bone marrow and peripheral blood isolates in the case group were identical. None of the children identified as having an X4 strain developed a (new episode of severe anaemia during follow up. Conclusion

  19. Idiopathic Inflammatory Myopathies; Association with Overlap Myositis and Syndromes: Classification, Clinical Characteristics, and Associated Autoantibodies

    2016-07-01

    Full Text Available Idiopathic inflammatory myopathies (IIM are traditionally identified as a group of disorders that target skeletal muscle due to autoimmune dysfunction. The IIM can be divided into subtypes based on certain clinical characteristics, and several classification schemes have been proposed. The predominant diagnostic criteria for IIM is the Bohan and Peter criteria, which subdivides IIM into primary polymyositis (PM, primary dermatomyositis (DM, myositis with another connective tissue disease, and myositis associated with cancer. However, this measure has been criticised for several reasons including lack of specific criteria to help distinguish between muscle biopsy findings of PM, DM, and immune-mediated necrotising myopathy, as well as the lack of identification of cases of overlap myositis (OM. Because of this issue, other classification criteria for IIM have been proposed, which include utilising myositis-associated antibodies and myositis-specific antibodies, as well as overlap features such as Raynaud’s phenomenon, polyarthritis, oesophageal abnormalities, interstitial lung disease, small bowel abnormalities such as hypomotility and malabsorption, and renal crises, amongst others. Indeed, the identification of autoantibodies associated with certain clinical phenotypes of myositis, in particular connective tissue disease-myositis overlap, has further helped divide IIM into distinct clinical subsets, which include OM and overlap syndromes (OS. This paper reviews the concepts of OM and OS as they pertain to IIM, including definitions in the literature, clinical characteristics, and overlap autoantibodies.

    Candida spp. is an invasive infectious fungus, a major risk factor that can increase morbidity and mortality in hospitalized patients. In this study, 2,508 Candida spp. were isolated from various clinical specimens collected from university hospitals from July 2011 to October 2014. They were identified in order to determine isolation frequencies and characteristics by specimen, gender, age group, year, season, and month. The strain-specific isolation rate of Candida spp. is in the order of Candida albicans (1,218 strains, 48.56%), Candida glabrata (416 strains, 16.59%), Candida utilis (305 strains, 12.16%), Candida tropicalis (304 strains, 12.12%), and Candida parapsilosis (116 strains, 4.63%) and these five species accounted for more than 94% of the total strains. Of the specimens, Candida spp. were most frequently isolated from urine-catheter, followed by urine-voided, blood, sputum, other, open pus, vaginal discharge, Tip, ear discharge, bronchial aspiration and bile, in that order. Looking at the age distribution, the detection rate of patients in their 60s and older was significantly higher at 75.8% (1,900/2,508). The detection rate of patients in their 20s and younger was shown to be very low at 2.55% (64/2,508). By year, the detection rate of non-albicans Candida spp. showed a tendency to gradually increase each year compared with C. albicans. As isolation of Candida spp. from clinical samples at the specie level can vary depending on characteristics of the patient, sample, season, etc., continual studies are required.

    2017-03-01

    In the present investigation, high-temperature compression tests were conducted at strain rates of 0.001 to 0.1 s-1 and at temperatures of 873 K to 1173 K (600 °C to 900 °C) in order to study the hot deformation characteristics and dynamic softening mechanisms of two different grades of commercial purity titanium after severe plastic deformation. It was observed that the effects of deformation rate and temperature are significant on obtained flow stress curves of both grades. Higher compressive strength exhibited by grade 2 titanium at relatively lower deformation temperatures was attributed to the grain boundary characteristics in relation with its lower processing temperature. However, severely deformed grade 4 titanium demonstrated higher compressive strength at relatively higher deformation temperatures (above 800 °C) due to suppressed grain growth via oxygen segregation limiting grain boundary motion. Constitutive equations were established to model the flow behavior, and the validity of the predictions was demonstrated with decent agreement accompanied by average error levels less than 5 pct for all the deformation conditions.

    With both sides of the Taklimakan Desert highway line as the study area, three typical aeolian sand landforms, i.e. complex dune ridge, barchan dune and flat sand land, were selected as sand beds for the observation, analysis and research of the characteristics of aeolian sand movement such as aeolian sand stream structure, sand transport intensity, etc. in the Taklimakan Desert. The results show that there is a linear relation between the height and the log of sand transport rate over transverse dune chain, longitudinal dune ridge and flat sand land, i.e. the sand transport percentage decreases exponentially with increasing height. Sand transport rate within the 10 cm height above the bed surface accounts for 80%-95% of the total sand transport rate of the observed height (40 cm), while the sand transport rate in 20 cm occupies 98% of the total amount. Sand transport rate (g·cm-1·min-1) differs greatly with respect to different landform types and different topographic positions. Based on the investigation and analysis on aeolian sand landform origin, morphological type and distribution feature, the two typical landform assemblages, complex transverse dune chain-alluvial plain and huge longitudinal dune ridge-interridge lowland in the Taklimakan Desert were divided into several characteristic zones of aeolian sand movement states. From this one can qualitatively judge the types and severities of sand disasters at various topographic positions in the engineering installation region and further put forward concrete schemes and measures to control sand damages.

    Severe combined immunodeficiency (SCID) is one of the most severe forms of primary immunodeficiency characterized by absence of functional T lymphocytes. It is a paediatric emergency, which is life-threatening when recognized too late. The clinical presentation varies from the classical form of SCID through atypical SCID to Omenn syndrome. In addition, there is a considerable immunological variation, which can hamper the diagnosis. In this educational review, we describe the immunopathological background, clinical presentations and diagnostic process of SCID, as well as the therapeutic possibilities.

  9. From bedside to bench to clinic trials: identifying new treatments for severe asthma

    Full Text Available Asthmatics with a severe form of the disease are frequently refractory to standard medications such as inhaled corticosteroids, underlining the need for new treatments to prevent the occurrence of potentially life-threatening episodes. A major obstacle in the development of new treatments for severe asthma is the heterogeneous pathogenesis of the disease, which involves multiple mechanisms and cell types. Furthermore, new therapies might need to be targeted to subgroups of patients whose disease pathogenesis is mediated by a specific pathway. One approach to solving the challenge of developing new treatments for severe asthma is to use experimental mouse models of asthma to address clinically relevant questions regarding disease pathogenesis. The mechanistic insights gained from mouse studies can be translated back to the clinic as potential treatment approaches that require evaluation in clinical trials to validate their effectiveness and safety in human subjects. Here, we will review how mouse models have advanced our understanding of severe asthma pathogenesis. Mouse studies have helped us to uncover the underlying inflammatory mechanisms (mediated by multiple immune cell types that produce Th1, Th2 or Th17 cytokines and non-inflammatory pathways, in addition to shedding light on asthma that is associated with obesity or steroid unresponsiveness. We propose that the strategy of using mouse models to address clinically relevant questions remains an attractive and productive research approach for identifying mechanistic pathways that can be developed into novel treatments for severe asthma.

    Dengue is a potentially life-threatening illness, and children are at higher risk of severity. This review aimed to systematize the identified clinical and laboratory parameters associated with severe dengue in children, as monitoring these signs and fluid-replacement therapy are actually the cornerstones of dengue treatment. Of the 527 studies initially reviewed, 21 were selected as follows: three cohort studies, three case-control studies, 14 cross-sectional studies and one not defined. Eighteen studies were carried out in Asia and three in the Americas. Hepatomegaly, lethargy, abdominal pain, bleeding, hemoconcentration and thrombocytopenia, all referenced as warning signs in the WHO 2009 Guidelines, were the clinical and laboratory parameters independently associated with severity in more than one study. The recognition of these known warning signs associated to severe dengue disease underlines the usefulness of the WHO 2009 classification.

    Despite the same manufacturer, the same drotrecogin alfa activated dose, and the same placebo-controlled design, the negative result from the PROWESS-SHOCK trial contradicted the survival benefit observed in the PROWESS trial. We hypothesize that the different results were due to factors other than the experimental therapy and performed an analysis of the clinical heterogeneity (differences related to the trials' clinical aspects) and the statistical heterogeneity (differences related to the trials' statistical aspects) between these trials. Baseline characteristics and co-interventions were analyzed by chi-square testing and mortality was analyzed by random-effects modeling and I2. Our findings show that clinical variables presented significant heterogeneity, and that up to 90% of the mortality differences between both trials were not due to chance. These results demonstrate that PROWESS and PROWESS-SHOCK are not comparable trials due to the highly significant clinical and statistical heterogeneity. We propose a new and pragmatic solution.

    Marfan syndrome is an autosomal dominant heritable disorder of the connective tissue, caused by mutations of the gene FBN1, which encodes fibrillin-1, a major component of the microfibrils of the extracellular matrix. Fibrillin-1 interacts with transforming growth factor-β (TGF-β), and dysregulated TGF-β signaling plays a major role in the development of connective tissue disease and familial aortic aneurysm and dissection, including Marfan syndrome. Losartan, an angiotensin II blocker, has the potential to reduce TGF-β signaling and is expected to be an additional therapeutic option. Clinical diagnosis is made using the Ghent nosology, which requires comprehensive patient assessment and has been proven to work well, but evaluation of some of the diagnostic criteria by a single physician is difficult and time-consuming. A Marfan clinic was established at the University of Tokyo Hospital in 2005, together with cardiologists, cardiac surgeons, pediatricians, orthopedists, and ophthalmologists in one place, for the purpose of speedy and accurate evaluation and diagnosis of Marfan syndrome. In this review, we discuss the recent progress in diagnosis and treatment of Marfan syndrome, and the characteristics of Japanese patients with Marfan syndrome.

Methods: The hospital records of patients who were hospitalized with the diagnosis of KD in the Pediatrics Clinics of Konya Training and Research Hospital between May 2010 and June 2012 were reviewed retrospectively. Results: Seven cases were found to have the diagnosis of KD, two of whom were incomplete KD. Oropharynx changes were the most common (100% feature in our patients. Five (71% patients had bulbar conjunctivitis. Three (43% patients had erythema at the site of BCG inoculation. Adenopathy was present in all of our patients with the classical form. A desquamation was observed in one case at the seventh day of fever. No cardiac manifestation was seen. Elevated erythrocyte sedimentation rate and thrombocytosis were present in all patients. All of the patients were received intravenous immunoglobulin in the first ten days of the fever. Conclusion: KD should be considered as a possible diagnosis in any child presenting with prolonged fever. BCG reaction can be attributed as a diagnostic criterion for incomplete form of the disease especially in countries where BCG vaccination is routinely performed. Early treatment is essential to prevent cardiovascular complications.

    Leprosy is a chronic disease caused by Mycobacterium leprae. Although the occurrence of leprosy has declined in Saudi Arabia, it has not yet been eradicated. To our knowledge, this descriptive retrospective study is the first to assess the clinical presentation of leprosy at the time of diagnosis in Saudi Arabia. All study subjects were leprosy patients admitted to Ibn Sina hospital, the only referral hospital for leprosy in Saudi Arabia, between January 2000 and May 2012. A total of 164 subjects, the majority of whom (65%) were between 21 and 50 years of age, were included, and the male-to-female ratio was 2.8:1. Of these 164 patients, 63% were Saudis, and 77% of all admitted patients were from the western region. Lepromatous leprosy was observed most frequently (33%), and 31% of cases had a positive history of close contact with leprosy. At the time of diagnosis, 84% of all subjects presented with skin manifestation. The prevalence of neurological deficit at the time of diagnosis was 87%. Erythema nodosum leprosum (E.N.L.) developed in only 10% of all subjects. Further studies are needed to determine the clinical characteristics pertaining to each type of leprosy in the region, and training courses in caring for and diagnosing patients with leprosy should be organized for health workers.

    Full Text Available Abstract Background Clinical trial and epidemiological studies need high quality biospecimens from a representative sample of participants to investigate genetic influences on treatment response and disease. Obtaining blood biospecimens presents logistical and financial challenges. As a result, saliva biospecimen collection is becoming more frequent because of the ease of collection and lower cost. This article describes an assessment of saliva biospecimen samples collected through the mail, trial participant demographic and behavioral characteristics, and their association with saliva and DNA quantity and quality. Methods Saliva biospecimens were collected using the Oragene® DNA Self-Collection Kits from participants in a National Cancer Institute funded smoking cessation trial. Saliva biospecimens from 565 individuals were visually inspected for clarity prior to and after DNA extraction. DNA samples were then quantified by UV absorbance, PicoGreen®, and qPCR. Genotyping was performed on 11 SNPs using TaqMan® SNP assays and two VNTR assays. Univariate, correlation, and analysis of variance analyses were conducted to observe the relationship between saliva sample and participant characteristics. Results The biospecimen kit return rate was 58.5% among those invited to participate (n = 967 and 47.1% among all possible COMPASS participants (n = 1202. Significant gender differences were observed with males providing larger saliva volume (4.7 vs. 4.5 ml, p = 0.019, samples that were more likely to be judged as cloudy (39.5% vs. 24.9%, p 0.21, P Conclusion Findings from this study show that demographic and behavioral characteristics of smoking cessation trial participants have significant associations with saliva and DNA metrics, but not with the performance of TaqMan® SNP or VNTR genotyping assays.

    Abstract It is important to identify the severity of acute pancreatitis (AP) in the early course of the disease. Clinical scoring systems may be helpful to predict the prognosis of patients with early AP; however, few analysts have forecast the accuracy of scoring systems for the prognosis in hyperlipidemic acute pancreatitis (HLAP). The purpose of this study was to summarize the clinical characteristics of HLAP and compare the accuracy of conventional scoring systems in predicting the prognosis of HLAP. This study retrospectively analyzed all consecutively diagnosed AP patients between September 2008 and March 2014. We compared the clinical characteristics between HLAP and nonhyperlipidemic acute pancreatitis. The bedside index for severity of acute pancreatitis (BISAP), Ranson, computed tomography severity index (CTSI), and systemic inflammatory response syndrome (SIRS) scores were applied within 48 hours following admission. Of 909 AP patients, 129 (14.2%) had HLAP, 20 were classified as severe acute pancreatitis (SAP), 8 had pseudocysts, 9 had pancreatic necrosis, 30 had pleural effusions, 33 had SIRS, 14 had persistent organ failure, and there was 1 death. Among the HLAP patients, the area under curves for BISAP, Ranson, SIRS, and CTSI in predicting SAP were 0.905, 0.938, 0.812, and 0.834, 0.874, 0.726, 0.668, and 0.848 for local complications, and 0.904, 0.917, 0.758, and 0.849 for organ failure, respectively. HLAP patients were characterized by younger age at onset, higher recurrence rate, and being more prone to pancreatic necrosis, organ failure, and SAP. BISAP, Ranson, SIRS, and CTSI all have accuracy in predicting the prognosis of HLAP patients, but each has different strengths and weaknesses. PMID:26061329

    Full Text Available Purpose. To define specific features of central hemodynamic parameter changes in patients with isolated severe traumatic brain injury (STBI and in patients with clinically established brain death and to determine the required course of treatment for their correction. Data and Research Methods. A close study of central hemodynamic parameters was undertaken. The study involved 13 patients with isolated STBI (group STBI and 15 patients with isolated STBI and clinically established brain death (group STBI-BD. The parameters of central hemodynamics were researched applying transpulmonary thermodilution. Results. In the present study, various types of hemodynamic reaction (normodynamic, hyperdynamic, and hypodynamic were identified in patients with isolated STBI in an acute period of traumatic disease. Hyperdynamic type of blood circulation was not observed in patients with isolated STBI and clinically established brain death. Detected hemodynamic disorders led to the correction of the ongoing therapy under the control of central hemodynamic parameters. Conclusions. Monitoring of parameters of central hemodynamics allows to detect the cause of disorders, to timely carry out the required correction, and to coordinate infusion, inotropic, and vasopressor therapy.

    Claudin-low breast cancer is a molecular type of breast cancer originally identified by gene expression profiling and reportedly associated with poor survival. Claudin-low tumors have been recognised to preferentially display a triple-negative phenotype, however only a minority of triple-negative breast cancers are claudin-low. We sought to identify an immunohistochemical profile for claudin-low tumors that could facilitate their identification in formalin fixed paraffin embedded tumor material. First, an in silico collection of ~1600 human breast cancer expression profiles was assembled and all claudin-low tumors identified. Second, genes differentially expressed between claudin-low tumors and all other molecular subtypes of breast cancer were identified. Third, a number of these top differentially expressed genes were tested using immunohistochemistry for expression in a diverse panel of breast cancer cell lines to determine their specificity for claudin-low tumors. Finally, the immunohistochemical panel found to be most characteristic of claudin-low tumors was examined in a cohort of 942 formalin fixed paraffin embedded human breast cancers with >10 years clinical follow-up to evaluate the clinico-pathologic and survival characteristics of this tumor subtype. Using this approach we determined that claudin-low breast cancer is typically negative for ER, PR, HER2, claudin 3, claudin 4, claudin 7 and E-cadherin. Claudin-low tumors identified with this immunohistochemical panel, were associated with young age of onset, higher tumor grade, larger tumor size, extensive lymphocytic infiltrate and a circumscribed tumor margin. Patients with claudin-low tumors had a worse overall survival when compared to patients with luminal A type breast cancer. Interestingly, claudin-low tumors were associated with a low local recurrence rate following breast conserving therapy. In conclusion, a limited panel of antibodies can facilitate the identification of claudin-low tumors

    Full Text Available Objective: The aim of this study is to present a comprehensive profile of clinical and psychosocial characteristics of children with psychogenic nonepileptic seizures and to assess the short-term outcome of these patients. Materials and Methods: The subjects were consecutive cases of children with a diagnosis of nonepileptic seizures (N=17, mean age = 10.7 years, S.D. = 1.26 and two groups of control groups matched on age and sex: true seizure group and healthy controls. All the children were recruited from the out-patient services of the Department of Pediatrics of a tertiary care teaching hospital in North India. Detailed history taking and clinical examination was done in the case of every child. A standard 18 channel EEG was done in all the children and a video EEG was done in 12 cases of children with nonepileptic seizures. The Childhood Psychopathology Measurement Schedule (CPMS and Life Events Scale for Indian Children (LESIC were used to measure the children′s emotional and behavioral functioning at home, and the number of life events and the stress associated with these events in the preceding year and the year before that. Short-term outcome was examined three to six months after the diagnosis of nonepileptic seizures was made. Results: Unresponsiveness without marked motor manifestations was the most common "ictal" characteristic of the nonepileptic seizures. Pelvic thrusting, upper and lower limb movements, head movements, and vocalization were observed in less than one-third of the patients. Increased psychosocial stress and significantly higher number of life events in the preceding year were found to characterize children with nonepileptic seizures, as compared to the two control groups. The nonepileptic seizures and true seizures groups had a higher proportion of children with psychopathology scores in the clinically significant maladjustment range, as compared to those in the healthy control group. A majority of the patients

    Electroencephalograms are widely used to detect interictal epileptiform discharges (IEDs) in patients with a known history of seizures. However, previous studies have not found a consistent association between the presence or frequency of IEDs and clinical epilepsy severity, possibly because of differences in subject characteristics and recording techniques. We sought to investigate this relationship in a population and setting reflective of the most common clinical usage. We analyzed electroencephalograms and clinical records of all consenting patients with a history of at least two presumed focal-onset seizures who presented for routine electroencephalograms recording over 1-year time in an academic neurophysiology laboratory (n = 129). Despite adequate statistical power, we did not find an association between the presence or absence of IEDs or IED frequency and the most recently determined seizure frequency (median, 4 per year). A higher IED incidence was seen in subjects with longer epilepsy duration (P = 0.04). Neither IED incidence nor frequency (median, 10.0 per hour) correlated with age or antiepileptic drug use. Our results differ from those of some previous studies, most of which focused on more narrow subject populations, suggesting that the patient's clinical circumstances must be taken into account before assuming the utility of IEDs on routine electroencephalography in predicting epilepsy severity.

    Full Text Available Background: It has been proposed that hepatitis C virus (HCV antigens are involved in the pathogenesis of psoriasis and may contribute to severity of the disease. Increased expression of the apoptosis-regulating proteins p53 and tTG and decreased levels of bcl-2 in the keratinocytes of the skin of psoriatic patients have been reported. Aim: This study aims to identify the serum levels of apoptosis-regulating proteins in patients with psoriasis and without HCV infection and to study the relation between clinical severity of psoriasis and the presence of HCV infection. Materials and Methods: Disease severity was assessed by psoriasis area severity index score (PASI of 90 patients with psoriasis grouped as mild (n = 30, moderate (n = 30 and severe (n = 30; 20 healthy individuals were used as controls. All groups were subjected for complete history taking, clinical examination, and tests for liver function and HCV infection. The serum levels of apoptosis related proteins: p53, tTG and bcl-2 were estimated by enzyme linked immune sorbent assay (ELISA. Results: There was a statistically significant (P < 0.001 correlation between clinical severity of psoriasis and presence of HCV antibodies and HCV-mRNA. In addition, significantly (P < 0.001 raised serum p53 and tTG, and reduced bcl-2 were observed among HCV-positive patients as compared to HCV-negative patients and control patients. Conclusion: These results conclude that clinical severity of psoriasis is affected by the presence of HCV antibodies and overexpression of apoptotic related proteins. In addition, altered serum levels of apoptosis-regulating proteins could be useful prognostic markers and therapeutic targets of psoriatic disease.

    The incidence of fetal tumors has been increased due to generalization of prenatal evaluation and improvement of imaging techniques. The early detection of a fetal tumor and understanding of its imaging features are very important for fetal, maternal, and neonatal care. Ultrasonography is usually used for the detection and differential diagnosis of fetal tumors, and magnetic resonance imaging is increasingly being used as a complementary study. Many fetal tumors have different clinical and imaging features compared with pediatric tumors. Although several fetal tumors may mimic other common anomalies, some specific imaging features may carry early accurate diagnosis of fetal tumors, which may alter the prenatal management of a pregnancy and the mode of delivery, and facilitate immediate postnatal treatment.

    Solar absorption characteristics are established for several films potentially favorable for use as receiving surfaces in solar energy collectors. Included in the investigation were chemically produced black films, black electrodeposits, and anodized coatings. It was found that black nickel exhibited the best combination of selective optical properties of any of the coatings studied. A serious drawback to black nickel was its high susceptibility to degradation in the presence of high moisture environments. Electroplated black chrome generally exhibited high solar absorptivities, but the emissivity varied considerably and was also relatively high under some conditions. The black chrome had the greatest moisture resistance of any of the coatings tested. Black oxide coatings on copper and steel substrates showed the best combination of selective optical properties of any of the chemical conversion films studied.

    Full Text Available This article concerns the oblique derivative problems for second-order quasilinear degenerate equations of mixed type with several characteristic boundaries, which include the Tricomi problem as a special case. First we formulate the problem and obtain estimates of its solutions, then we show the existence of solutions by the successive iterations and the Leray-Schauder theorem. We use a complex analytic method: elliptic complex functions are used in the elliptic domain, and hyperbolic complex functions in the hyperbolic domain, such that second-order equations of mixed type with degenerate curve are reduced to the first order mixed complex equations with singular coefficients. An application of the complex analytic method, solves (1.1 below with $m=n=1$, $a=b=0$, which was posed as an open problem by Rassias.

    Controversy over abortion inhibits recognition and treatment for women who experience psychological distress after abortion (PAD). This study identified the characteristics, severity, and treatment preferences of university students who experienced PAD. Of 151 females, 89 experienced an abortion. Psychological outcomes were compared among those who preferred or did not prefer psychological services after abortion to those who were never pregnant. All who had abortions reported symptoms of post-traumatic stress disorder (PTSD) and grief lasting on average 3 years. Yet, those who preferred services experienced heightened psychological trauma indicative of partial or full PTSD (Impact of Event Scale, M = 26.86 versus 16.84, p abortion and overall emotional health. Thus, psychological interventions for PAD need to be developed as a public health priority.

    2002-01-01

    The contribution of the high LET particles to dosimetric and microdosimetric characteristics of 150 and 205 MeV clinical proton beams was experimentally studied using track etched detectors. Secondary heavy charged particles produced from nuclear interactions and degraded protons at the Bragg peak region are particles with high LET. The method of the LET spectra measurement with track etched detectors allows one to determine the contribution of high LET particles to dosimetric characteristics of clinical proton beams: absorbed dose, equivalent dose and the value of the Relative Biological Effectiveness (RBE). Track detectors were irradiated in the various depth of clinical proton beams with the primary energies of 150 and 205 MeV. The LET spectra between 10 and 700 keV/m were measured by means of CR-39 track etched detectors and the automatic optical image analyzer LUCIA-II. The relative contribution of the high LET particles to absorbed dose increases from several per cent at the beam entrance to several ten...

    Objective To investigate the clinical characteristics of fetal hydrops and to find the antenatal ultrasound findings predictive of adverse perinatal outcome. Methods This is a retrospective study of 42 women with fetal hydrops who delivered in a tertiary-referral center from 2005 to 2013. Fetal hydrops was defined as the presence of fluid collection in ≥2 body cavities: ascites, pleural effusion, pericardial effusion, and skin edema. Predictor variables recorded included: maternal characteristics, gestational age at diagnosis, ultrasound findings, and identifiable causes. Primary outcome variables analyzed were fetal death and neonatal death. Results The mean gestational age at diagnosis was 29.3±5.4 weeks (range, 18 to 39 weeks). The most common identifiable causes were cardiac abnormality (10), followed by syndrome (4), aneuploidy (3), congenital infection (3), twin-to-twin transfusion syndrome (3), non-cardiac anormaly (2), chorioangioma (2), inborn errors of metabolism (1), and immune hydrops by anti-E antibody isoimmunization (1). Thirteen cases had no definite identifiable causes. Three women elected termination of pregnancy. Fetal death occurred in 4 cases. Among the 35 live-born babies, only 16 survived (54.0% neonatal mortality rate). Fetal death and neonatal mortality rate was not significantly associated with Doppler velocimetry indices or location of fluid collection, but increasing numbers of fluid collection site was significantly associated with a higher risk of neonatal death. Conclusion The incidence of fetal hydrops in our retrospective study was 24.4 per 10,000 deliveries and the perinatal mortality rate was 61.9% (26/42). The number of fluid collection sites was the significant antenatal risk factor to predict neonatal death. PMID:25798421

    Background Spontaneous attack of variant angina (VA) is a unique component of coronary artery disease (CAD), and associated with severe cardiac events. However, no data are available regarding sex differences in Chinese patients with spontaneous attacks of VA. Accordingly, the present retrospective study was initiated to evaluate the Clinical characteristics of Chinese female patients with spontaneous attacks of VA.Methods From January 2003 to January 2008, a total of 209 patients were diagnosed to have had a spontaneous attack of VA at Fu Wai Hospital. Of them, 27 were female, and their clinical findings were collected and compared with male patients for aspects of risk factors, clinical features and angiographical findings.Results Spontaneous attacks of VA was relatively uncommon in female (12.9%) compared with male patients. The female patients were less likely to have a history of smoking (14.8% vs. 79.7%, P <0.001), more likely to have a family history of CAD (33.3% vs. 11.0%, P<0.01), and to have had a greater incidence of ventricular fibrillation during attack (11.1% vs. 2.2%, P<0.05). There were no significant differences in other characteristics between the two groups.Conclusion Chinese female patients who experienced a spontaneous attack of VA had the characteristics of less smoking history, more family history of CAD and higher occurrence of ventricular fibrillation than male patients.

  1. Trauma-associated tinnitus: audiological, demographic and clinical characteristics.

    Directory of Open Access Journals (Sweden)

    Peter M Kreuzer

    Full Text Available BACKGROUND: Tinnitus can result from different etiologies. Frequently, patients report the development of tinnitus after traumatic injuries. However, to which extent this specific etiologic factor plays a role for the phenomenology of tinnitus is still incompletely understood. Additionally, it remains a matter of debate whether the etiology of tinnitus constitutes a relevant criterion for defining tinnitus subtypes. OBJECTIVE: By investigating a worldwide sample of tinnitus patients derived from the Tinnitus Research Initiative (TRI Database, we aimed to identify differences in demographic, clinical and audiological characteristics between tinnitus patients with and without preceding trauma. MATERIALS: A total of 1,604 patients were investigated. Assessment included demographic data, tinnitus related clinical data, audiological data, the Tinnitus Handicap Inventory, the Tinnitus Questionnaire, the Beck Depression Inventory, various numeric tinnitus rating scales, and the World Health Organisation Quality of Life Scale (WHOQoL. RESULTS: Our data clearly indicate differences between tinnitus patients with and without trauma at tinnitus onset. Patients suffering from trauma-associated tinnitus suffer from a higher mental burden than tinnitus patients presenting with phantom perceptions based on other or unknown etiologic factors. This is especially the case for patients with whiplash and head trauma. Patients with posttraumatic noise-related tinnitus experience more frequently hyperacousis, were younger, had longer tinnitus duration, and were more frequently of male gender. CONCLUSIONS: Trauma before tinnitus onset seems to represent a relevant criterion for subtypization of tinnitus. Patients with posttraumatic tinnitus may require specific diagnostic and therapeutic management. A more systematic and - at best - standardized assessment for hearing related sequelae of trauma is needed for a better understanding of the underlying pathophysiology and

    Full Text Available Personality disorders are common in subjects with panic disorder. Personality disorders have shown to affect the course of panic disorder. The purpose of this study was to examine which personality disorders effect clinical severity in subjects with panic disorder. This study included 122 adults (71 female, 41 male, who met DSM-IV criteria for panic disorder (with or without agoraphobia. Clinical assessment was conducted by using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II and the Panic and Agoraphobia Scale (PAS, Global Assessment Functioning Scale (GAF, Beck Depression Inventory (BDI, and State-Trait Anxiety Inventory (STAI. Patients who had a history of sexual abuse were assessed with Sexual Abuse Severity Scale. Logistic regressions were used to identify predictors of suicide attempts, suicidal ideation, agoraphobia, different panic attack symptoms, sexual abuse, and early onset of disorders. The rates of comorbid Axis I and Axis II psychiatric disorders were 80.3% and 33.9%, consecutively, in patients with panic disorder. Panic disorder patients with comorbid personality disorders had more severe anxiety, depression and agoraphobia symptoms, and had earlier ages of onset, and lower levels of functioning. The rates of suicidal ideation and suicide attempts were 34.8% and 9.8%, consecutively, in subjects with panic disorder. The rate of patients with panic disorder had a history of childhood sexual abuse was 12.5%. The predictor of sexual abuse was more than one comorbid Axis II diagnosis. The predictors of suicide attempt were comorbid paranoid and borderline personality disorders, and the predictor of suicidal ideation was major depressive disorder in subjects with panic disorder. In conclusion, this study documents that comorbid personality disorders increase the clinical severity of panic disorder. Patients with more than one

    Full Text Available Clinical characteristics associated with isolation of Borrelia burgdorferi sensu lato from skin have not been fully evaluated. To gain insight into predictors for a positive EM skin culture, we compared basic demographic, epidemiologic, and clinical data in 608 culture-proven and 501 culture-negative adult patients with solitary EM. A positive Borrelia spp. skin culture was associated with older age, a time interval of >2 days between tick bite and onset of the skin lesion, EM ≥ 5 cm in diameter, and location of the lesion on the extremities, whereas several other characteristics used as clinical case definition criteria for the diagnosis of EM (such as tick bite at the site of later EM, information on expansion of the skin lesion, central clearing were not. A patient with a 15-cm EM lesion had almost 3-fold greater odds for a positive skin culture than patients with a 5-cm lesion. Patients with a free time interval between the tick bite and onset of EM had the same probability of a positive skin culture as those who did not recall a tick bite (OR=1.02; however, the two groups had >3-fold greater odds for EM positivity than patients who reported a tick bite with no interval between the bite and onset of the lesion. In conclusion, several yet not all clinical characteristics used in EM case definitions were associated with positive Borrelia spp. skin culture. The findings are limited to European patients with solitary EM caused predominantly by B. afzelii but may not be valid for other situations.

    James A Potts

    Full Text Available Dengue virus is endemic in tropical and sub-tropical resource-poor countries. Dengue illness can range from a nonspecific febrile illness to a severe disease, Dengue Shock Syndrome (DSS, in which patients develop circulatory failure. Earlier diagnosis of severe dengue illnesses would have a substantial impact on the allocation of health resources in endemic countries.We compared clinical laboratory findings collected within 72 hours of fever onset from a prospective cohort children presenting to one of two hospitals (one urban and one rural in Thailand. Classification and regression tree analysis was used to develop diagnostic algorithms using different categories of dengue disease severity to distinguish between patients at elevated risk of developing a severe dengue illness and those at low risk. A diagnostic algorithm using WBC count, percent monocytes, platelet count, and hematocrit achieved 97% sensitivity to identify patients who went on to develop DSS while correctly excluding 48% of non-severe cases. Addition of an indicator of severe plasma leakage to the WHO definition led to 99% sensitivity using WBC count, percent neutrophils, AST, platelet count, and age.This study identified two easily applicable diagnostic algorithms using early clinical indicators obtained within the first 72 hours of illness onset. The algorithms have high sensitivity to distinguish patients at elevated risk of developing severe dengue illness from patients at low risk, which included patients with mild dengue and other non-dengue febrile illnesses. Although these algorithms need to be validated in other populations, this study highlights the potential usefulness of specific clinical indicators early in illness.

    2012-01-01

    Full Text Available Human rhinovirus (HRV is a leading cause of acute respiratory infection (ARI in young children and infants worldwide and has a high impact on morbidity and mortality in this population. Initially, HRV was classified into two species: HRV-A and HRV-B. Recently, a species called HRV-C and possibly another species, HRV-D, were identified. In Mexico, there is little information about the role of HRV as a cause of ARI, and the presence and importance of species such as HRV-C are not known. The aim of this study was to determine the clinical characteristics and genetic variability of HRV in Mexican children. Genetic characterization was carried out by phylogenetic analysis of the 5′-nontranslated region (5′-NTR of the HRV genome. The results show that the newly identified HRV-C is circulating in Mexican children more frequently than HRV-B but not as frequently as HRV-A, which was the most frequent species. Most of the cases of the three species of HRV were in children under 2 years of age, and all species were associated with very mild and moderate ARI.

    Chiropractic services have been delivered on station at select Veterans Health Administration (VHA) medical facilities since late 2004. No published data describing the characteristics of VHA chiropractic physicians (chiropractors) and chiropractic clinics exist at a national level. This study was designed to examine elements of the structures of chiropractic services in VHA settings. Web-based survey methods were used to question all chiropractors in VHA facilities (N = 36). Data were obtained from 33 providers, yielding a 91.6% response rate. Most respondents were full-time VHA employees, while others were part-time employees or contractors. Differences were found in prior training, integrated practice, and academic or research experience. Of the respondents, 88% ranked low back pain as the most common patient complaint seen in practice and 79% ranked cervical pain the second most common complaint. Of the new patient consultations, 67.6% originated from primary care, 9.4% from pain management, and 6.2% from physiatry. Most respondents were similar in their reported use of diagnostic and therapeutic procedures, but their reported rates of participation in various facility activities were different. Further work is needed for researchers and policy makers to more fully understand the integration and delivery of chiropractic services in VHA settings.

    Purpose: The spinal epidural angiolipomas are rare expansive processes made of mature lipomatous and angiomatous elements. They often have a benign character. Their etiology, pathogenesis remains uncertain, and it is a cause of spinal cord compression. The magnetic resonance imaging is the most important neuroradiological examination. Histological examination is the only examination to confirm the diagnosis. Surgery is the treatment of choice. Methods: A retrospective study of all patients operated on for a spinal epidural angiolipoma at the Department of Neurosurgery at the National Institute of Neurology of Tunis between January 2000 and December 2014 (15 years) was performed. The aim of this study is to describe the clinical, radiological, histological characteristics and the treatment of this tumor. Results: A total of nine patients were operated from January 01, 2000 to November 30, 2014. The average age of our patients was 51 years with ages that ranged from 29 to 65 with a male predominance. The period between onset of symptoms and diagnosis ranged from 24 months with an average 12 months. Posterior localization of the tumor was seen in all patients. Surgical resection was performed for all cases. The postoperative course has been satisfactory, with a complete recovery of neurological functions in all patients. Conclusions: The spinal epidural angiolipomas is rare expansive process causing spinal cord compression. Treatment is exclusively surgical resection. The functional outcome of spinal epidural angiolipomas is particularly favorable with a complete neurological recovery is if the patient was quickly operated. PMID:27695535

    Ocular candidiasis is a major complication of Candida bloodstream infection (BSI). This study was performed to reveal the clinical characteristics of ocular candidiasis. Of the 220 patients with Candida BSI, 204 cases received ophthalmology consultations between January 2005 and December 2011 at 2 teaching hospitals. Fifty-four (26.5%) cases had findings consistent with the diagnosis of ocular candidiasis. Of these 54 cases, 43 (79.6%) were diagnosed within 7 days after a positive blood culture. Among ocular candidiasis cases, more cases were due to Candida albicans (P =0.034 odds ratio [OR]; 3.68 95% confidence interval [CI] 1.11-12.2) and had higher β-d-glucan values (P = 0.001 OR; 9.99 95% CI 2.60-21.3). We need to consider fundoscopic examination to be performed within the first 7 days of therapy, especially for those patients who have C. albicans BSIs and higher β-d-glucan values. Additionally, follow-up fundoscopic examination should be considered before stopping therapy for high-risk patients.

    AIM: To evaluate the clinical characteristics and progression of liver abscess caused by toxocara.METHODS: We retrospectively reviewed the medical records of patients with serum Ig G antibody to Toxocara canis and liver abscess diagnosed using abdominal computed tomography between February 2010 and February 2015. Among 84 patients exhibiting serum Ig G antibody to Toxocara canis, 34 patients were diagnosed with liver asbscess and treated with albendazole. A follow-up period of 1 year was conducted. RESULTS: Mean patient age was 53(34-79) years, with 26(76.5%) patients being male. Twenty-one(61.7%) patients were moderate or heavy drinkers, 23(67.6%) patients had a history of eating raw meat or liver and 6(17.6%) patients owned pet dogs or cats. Main patient symptoms consisted of right upper quadrant pain, fever, and fatigue; 18(52.9%) patients, however, presented with no symptoms. Lung involvement was detected in 444(11.7%) patients. The eosinophil count increased in 29(85.3%) patients at initial diagnosis, and decreased in most patients after albendazole treatment. The initial serum Ig E level increased in 25(73.5%) patients, but exhibited various response levels after albendazole treatment. Liver abscess formation improved in all patients.CONCLUSION: The liver abscess was improved with albendazole treatment.

    The aim of this study was to examine the clinical characteristics of patients with gender identity disorder (GID) at a GID clinic in Japan. A total of 603 consecutive patients were evaluated at the GID clinic using clinical information and results of physical and neurological examinations. Using DSM-IV criteria, 579 patients (96.0%) were diagnosed with GID. Four patients were excluded for transvestic fetishism, eight for homosexuality, five for schizophrenia, three for personality disorders, and four for other psychiatric disorders. Among the GID patients, 349 (60.3%) were the female-to-male (FTM) type, and 230 (39.7%) were the male-to-female (MTF) type. Almost all FTM-type GID patients started to feel discomfort with their sex before puberty and were sexually attracted to females. The proportion of FTM patients who had experienced marriage as a female was very low, and very few had children. Therefore, FTM-type GID patients seem to be highly homogeneous. On the other hand, various patterns of age at onset and sexual attraction existed among MTF patients. Among the MTF-type GID patients, 28.3% had married as males and 18.7% had sired children. Thus, MTF-type GID patients seem to be more heterogeneous.

    Hereditary spherocytosis (HS) is usually classified as mild, moderate or severe using conventional features, namely, hemoglobin (Hb) concentration, reticulocyte count and bilirubin levels, which do not always contribute to an adequate clinical classification. The aim of our study was to establish the importance of some laboratory routine parameters, as markers of HS clinical outcome, by studying a control group (n=26) and unsplenectomized HS patients (n=82) presenting mild, moderate or severe HS. We performed a basic hematologic study and evaluated the reticulocyte count, bilirubin, erythropoietin (EPO) and soluble transferrin receptor (sTfR) levels; the osmotic fragility (OFT) and criohemolysis tests (CHT); the ratios Hb/MCHC (mean cell hemoglobin concentration), Hb/RDW (red cell distribution width) and MCHC/RDW, were calculated. Hb changed significantly in accordance with HS severity, but not reticulocytes or bilirubin. We found that MCHC, RDW, EPO, sTfR, OFT, CHT and the calculated ratios were significantly changed in patients, and, therefore, were valuable as complementary diagnostic tools for HS. Moreover, RDW, Hb/MCHC, Hb/RDW and MCHC/RDW changed significantly with worsening of HS; thus, they are also good markers for the clinical outcome of HS. In conclusion, we propose the use of these routine parameters as useful to complement the analysis of HS severity.

    In patients with meningococcal infection, devastating presentations, such as purpura fulminans, which can progress to extensive tissue necrosis of the limbs and digits, have a significant social impact. The case presented herein illustrates such a phenomenon in a patient who developed bilateral necrosis of the lower extremities as a result of infection with Neisseria meningitis. We emphasize that severe myalgia was the first clinical manifestation of meningococcal purpura fulminans in our case. However, myalgia has typically been overlooked and undervalued as an early clinical feature of meningococcal sepsis. Early recognition and prompt initial antibiotic therapy continue to be the cornerstones of the successful management of this dramatic disease, reducing morbidity and mortality.

    Full Text Available Objective: To describe the clinical and epidemiological characteristics, evolution and to identify mortality factors associated in patients with SNP. Material and Methods: Descriptive study of a serie of cases of the Intensive Care Unit (ICU of a General Hospital. Medical records of patients which received medical attention and who meet the selection criteria were reviewed Results: Forty-one clinical records were evaluated. The average age was 69 old, predominantly male (68,3%. SNP was the reason of admission in 60.9% and 95.1% required mechanical ventilation. Hospital stay prior to diagnosis was 10 days, 65% of patients had some risk factor for multi resistence organisms, CPIS of entry was 9.3, cultures were positive in 39% of the cases and of these, 48.8% received proper antibiotic according to culture results. The days of stay in ICU were 20.6 days and 20 of the 41 medical records were for death patients. The clinical and epidemiological characteristics were similar between death and alive patients. An analysis of factors that could be associated with mortality SNP was made and it was found that for an age ≥ 70 years, the presence of any risk factor for multidrug resistence organism and control CPIS ≥ 6 were associated with higher mortality; while acquisition of the ICU was associated to lower mortality. Conclusions: The clinical, epidemiological characteristics and evolution of patients with SNP in our ICU were similar to those describe in the literature. Three factors associated with mortality in the ICU were identified.

  18. Studying Different Clinical Syndromes Of Paediatric Severe Malaria Using Plasma Proteomics

    2012-08-01

    Background- Severe Plasmodium falciparum malaria remains one of the major causes of childhood morbidity and mortality in Africa. Severe malaria manifests itself as three main clinical syndromes-impaired consciousness (cerebral malaria), respiratory distress and severe malarial anaemia. Cerebral malaria and respiratory distress are major contributors to malaria mortality but their pathophysiology remains unclear. Motivation/Objectives- Most children with severe malaria die within the first 24 hours of admission to a hospital because of their pathophysiological conditions. Thus, along with anti-malarial drugs, various adjuvant therapies such as fluid bolus (for hypovolaemia) and anticonvulsants (for seizures) are given to alleviate the sick child’s condition. But these therapies can sometimes have adverse effects. Hence, a clear understanding of severe malaria pathophysiology is essential for making an informed decision regarding adjuvant therapies. Methodology- We used mass spectrometry-based shotgun proteomics to study plasma samples from Gambian children with severe malaria. We compared the proteomic profiles of different severe malaria syndromes and generated hypotheses regarding the underlying disease mechanisms. Results/Conclusions- The main challenges of studying the severe malaria syndromes using proteomics were the high complexity and variability among the samples. We hypothesized that hepatic injury and nitric oxide play roles in the pathophysiology of cerebral malaria and respiratory distress.

    Full Text Available Purpose: Mutations of the a-1 subunit sodium channel gene (SCN1A cause severe myoclonic epilepsy of infancy (SMEI. To date, over 300 mutations related to SMEI have been described. In the present study, we report new SCN1A mutations and the clinical features of SMEI cases. Materials and Methods: We studied the clinical and genetic features of nine patients diagnosed with SMEI at the Pediatric Neurology Department of Istanbul Medical Faculty. Results: Five patients had nonsense mutations, two had missense mutations, one had a splice site mutation and one had a deletion mutation of the SCN1A gene. Mutations at c.3705+5G splice site, p.trip153X nonsense mutation and deletion at c.2416_2946 have not been previously described. The seizures started following whole cell pertussis vaccination in all patients. The seizures ceased in one patient and continued in the other eight patients. Developmental regression was severe in three patients, with frequent status epilepticus. The type of mutation was not predictive for the severity of the disease. Two of the three patients with severe regression had nonsense and missense mutations. Conclusions : Dravet syndrome can be result of several different types of mutation in SCN1A gene. Onset of the seizures after pertussis vaccination is an important clue for the diagnosis and neuro- developmental delay should be expected in all patients.

    Abstract Background: Traumatic brain injury (TBI) is a debilitating medical and emerging public health problem that is affecting people worldwide due to a multitude of factors including both domestic and war-related acts. The objective of this paper is to systematically review the status of TBI in Lebanon – a Middle Eastern country with a weak health system that was chartered by several wars and intermittent outbursts of violence - in order to identify the present gaps in knowledge, direct future research initiatives and to assist policy makers in planning progressive and rehabilitative policies. Methods: OVID/Medline, PubMed, Scopus databases and Google Scholar were lastly searched on April 15th, 2016 to identify all published research studies on TBI in Lebanon. Studies published in English, Arabic or French that assessed Lebanese patients afflicted by TBI in Lebanon were warranting inclusion in this review. Case reports, reviews, biographies and abstracts were excluded. Throughout the whole review process, reviewers worked independently and in duplicate during study selection, data abstraction and methodological assessment using the Downs and Black Checklist. Results: In total, 11 studies were recognized eligible as they assessed Lebanese patients afflicted by TBI on Lebanese soils. Considerable methodological variation was found among the identified studies. All studies, except for two that evaluated domestic causes such as falls, reported TBI due to war-related injuries. Age distribution of TBI victims revealed two peaks, young adults between 18 and 40 years, and older adults aged 60 years and above, where males constituted the majority. Only three studies reported rates of mild TBI. Mortality, rehabilitation and systemic injury rates were rarely reported and so were the complications involved; infections were an exception. Conclusion: Apparently, status of TBI in Lebanon suffers from several gaps which need to be bridged through implementing more basic

    SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome includes both dermatological and rheumatologic symptoms. Being a rare condition, the diagnosis is frequently late. The authors report a case of a 13-year-old boy diagnosed with synovitis, acne, pustulosis, hyperostosis, and osteitis syndrome with unusual severe systemic repercussions. The patient presented with acne conglobata, inability to walk due to pain and weakness and weight loss. Bone scintigraphy was suggestive of sacroiliitis, and lumbar spine x-ray showed signs of hyperostosis. His clinical state improved after treatment with nonsteroidal anti-inflammatory drugs, methotrexate, clindamycin, and isotretinoin. A review of the clinical aspects of this syndrome is presented, emphasizing how this underdiagnosed syndrome can lead to severe weight loss and significant functional and psychological impairment at an early age.

    Gout is the most common form of inflammatory arthritis and it has an affliction to the foot. Foot involvement in gout has been linked to foot pain, impairment and disability. There has been limited research on the effect of ulceration on foot pain, impairment, disability and health-related quality of life in patients already living with gout. The aim of the study was to describe the wound characteristics and the effect on foot pain, disability and health-related quality of life in patients with foot ulceration associated with gout. Participants were recruited from rheumatology clinics in Auckland, New Zealand. All the current foot ulceration sites and wound characteristics were recorded using the TIME wound assessment tool. The outcome measures included general pain, patient global assessment scale, foot pain, disability and impairment. Participants completed the Cardiff Wound Impact Schedule to assess the effect of ulcers on health-related quality of life. Sensory loss, vibrational thresholds and ankle brachial pressure index were collated to assess for lower limb arterial disease. Six participants were predominantly older men with a long duration of gout, high rates of obesity and co-morbidities such as hypertension, hyperlipidaemia, diabetes and cardiovascular disease. The mean (SD) duration of the foot ulcers was 4 (2) months. The majority of foot ulcers observed were 0·5 cm(2) or smaller superficial thickness with surrounding callus. Partial thickness and full-thickness ulcers were also observed. Two patients presented with ulcers on multiple sites. There was only one case of infection. Gouty tophi were evident in most of the wounds. The dorsal aspect of the third toe was found to ulcerate in most cases. Moderate scores of foot pain, disability, impairment and health-related quality of life were observed. Most participants wore shoes deemed as poor. Foot ulceration in gout is chronic and multiple ulcers can occur with the potential of leading to delayed

    Inherited retinal degenerations (IRDs) encompass a large group of clinically and genetically heterogeneous diseases that affect approximately 1 in 3000 people (>2 million people worldwide) (Bessant DA, Ali RR, Bhattacharya SS. 2001. Molecular genetics and prospects for therapy of the inherited retinal dystrophies. Curr Opin Genet Dev 11: 307-316.). IRDs may be inherited as Mendelian traits or through mitochondrial DNA, and may affect the entire retina (e.g., rod-cone dystrophy, also known as retinitis pigmentosa, cone dystrophy, cone-rod dystrophy, choroideremia, Usher syndrome, and Bardet-Bidel syndrome) or be restricted to the macula (e.g., Stargardt disease, Best disease, and Sorsby fundus dystrophy), ultimately leading to blindness. IRDs are a major cause of severe vision loss, with profound impact on patients and society. Although IRDs remain untreatable today, significant progress toward therapeutic strategies for IRDs has marked the past two decades. This progress has been based on better understanding of the pathophysiological pathways of these diseases and on technological advances.

    Background and Objectives. The prevalence of severe obesity in children has doubled in the past decade. The objective of this study is to identify the clinical documentation of obesity in young children with a BMI ≥ 99th percentile at two large tertiary care pediatric hospitals. Methods. We used a standardized algorithm utilizing data from electronic health records to identify children with severe early onset obesity (BMI ≥ 99th percentile at age <6 years). We extracted descriptive terms and ICD-9 codes to evaluate documentation of obesity at Boston Children's Hospital and Cincinnati Children's Hospital and Medical Center between 2007 and 2014. Results. A total of 9887 visit records of 2588 children with severe early onset obesity were identified. Based on predefined criteria for documentation of obesity, 21.5% of children (13.5% of visits) had positive documentation, which varied by institution. Documentation in children first seen under 2 years of age was lower than in older children (15% versus 26%). Documentation was significantly higher in girls (29% versus 17%, p < 0.001), African American children (27% versus 19% in whites, p < 0.001), and the obesity focused specialty clinics (70% versus 15% in primary care and 9% in other subspecialty clinics, p < 0.001). Conclusions. There is significant opportunity for improvement in documentation of obesity in young children, even years after the 2007 AAP guidelines for management of obesity. PMID:27698673

    The purpose of this study was to estimate the general population lifetime and point prevalence of visual height intolerance and acrophobia, to define their clinical characteristics, and to determine their anxious and depressive comorbidities. A case-control study was conducted within a German population-based cross-sectional telephone survey. A representative sample of 2,012 individuals aged 14 and above was selected. Defined neurological conditions (migraine, Menière's disease, motion sickness), symptom pattern, age of first manifestation, precipitating height stimuli, course of illness, psychosocial impairment, and comorbidity patterns (anxiety conditions, depressive disorders according to DSM-IV-TR) for vHI and acrophobia were assessed. The lifetime prevalence of vHI was 28.5% (women 32.4%, men 24.5%). Initial attacks occurred predominantly (36%) in the second decade. A rapid generalization to other height stimuli and a chronic course of illness with at least moderate impairment were observed. A total of 22.5% of individuals with vHI experienced the intensity of panic attacks. The lifetime prevalence of acrophobia was 6.4% (women 8.6%, men 4.1%), and point prevalence was 2.0% (women 2.8%; men 1.1%). VHI and even more acrophobia were associated with high rates of comorbid anxious and depressive conditions. Migraine was both a significant predictor of later acrophobia and a significant consequence of previous acrophobia. VHI affects nearly a third of the general population; in more than 20% of these persons, vHI occasionally develops into panic attacks and in 6.4%, it escalates to acrophobia. Symptoms and degree of social impairment form a continuum of mild to seriously distressing conditions in susceptible subjects.

    Infiltrating lobular breast cancer (ILBC) is the most common special breast cancer subtype. This review provides a comprehensive description of ILBC characteristics, including epidemiology, clinical features, molecular genetics and histomorphology. Twenty detailed supplemental data tables guide through primary data of more than 200 original studies. Meta-analyses indicate that ILBC is at least twice as common in the Western world as it is in other geographic regions. ILBC is over-represented in so-called interval carcinomas and in primary metastatic breast cancer. ILBC is also associated higher age, higher pT stage and hormone receptor (ER/PR) positivity. Pathological complete response rates after neoadjuvant chemotherapy are low, ranging between 0% and 11%. Positive resection margins after breast-conserving surgery are comparatively frequent and 17% to 65% of patients undergo a second surgical intervention. Depending on the morphological stringency in the diagnosis of ILBC, lack of E-cadherin expression is observed in 55% to 100% of cases. CDH1/E-cadherin mutation detection rates vary between 12% and 83%. Various additional molecular factors, including PIK3CA, TP53, FOXA1, FGFR1, ZNF703 and BCAR4, have been implicated in ILBC or progression of lobular carcinoma in situ (LCIS) to invasive cancer and are discussed in detail. Eight instructive figure plates recapitulate the histomorphology of ILBC and its variants. Furthermore, we draw attention to rarely addressed histological details, such as two-sided nuclear compression and fat-avoiding growth at the invasion front. Last but not least, we discuss future translational research directions and emphasize the concept of synthetic lethality, which promises new options for targeted ILBC therapy.

    The impact of dynamic respiratory syncytial virus (RSV) load on the clinical severity of hospitalized infants with bronchiolitis has not been clarified. Nasopharyngeal aspirates were obtained from 60 infants who were diagnosed with bronchiolitis within 96 hr of wheezing onset upon admission and on days 3, 5, and 7 in the hospital, and 17 respiratory viruses were detected. The RSV load was quantified by real-time qPCR for RSV subtypes A and B at different time points. Scoring criteria were used to evaluate the degree of severity. A total of 40 infants were determined to be RSV-positive, nine were identified as RSV subtype A (RSVA), and 31 were RSV subtype B (RSVB). The peak RSV load was observed upon admission, and the RSV load decreased significantly over time; in addition, this decrease began to have significant differences on day 5. There was a positive correlation between the RSV load and the clinical score (r(2)  = 0.121 and P < 0.001). According to the clinical scores, the infants in the severe group tended to have higher RSV loads than those in the moderate and mild groups. Multivariate logistic regression models revealed that the viral load on day 3 was independently associated with the degree of severity. This study elucidated that a higher mean RSV load was associated with a more severe disease and a longer duration of hospitalization and symptoms. This study also clarified RSV replication in infants and provides a theoretical basis for specifying an anti-RSV therapy strategy.

    Full Text Available Context: Chronic inflammatory demyelinating polyradiculopathy (CIDP is an acquired and autoimmune neuropathy, characterized by a chronic, rapidly progressive, symmetric weakness. In children, abnormal gait is as a first symptom of muscle weakness. Evidence Acquisition: The diagnosis of CIDP is on the basis of clinical characteristics, electrodiagnostic that shows the severity of the disease, lumbar puncture and spine magnetic resonance imaging (MRI. Results: The first-line treatments in childhood CIDP are intravenous immunoglobulin (IVIG, corticosteroids, and plasmapheresis. Response to first-line therapies is usually satisfactory; nevertheless, recommendations regarding the choice of second-line therapy can only be prepared on the basis of the existing practice described in some of the case reports. Conclusions: This review demonstrated the clinical presentation, diagnosis, and treatment of childhood CIDP.

    Full Text Available Abstract Background Gaucher disease (GD is due to deficiency of the glucocerebrosidase enzyme. It is panethnic, but its presentation reveals ethnicity-specific characteristics. Methods We evaluated the distribution, and clinical and genetic characteristics of GD patients in the Iberian Peninsula (IP. We analysed geographical distribution, demographic, genetic and clinical data, age at diagnosis, type, and years of therapy in 436 GD patients from the IP. Results The prevalence of GD was 1/149,000 inhabitants; 88.3% were type 1, 6.7% type 2, and 5.0% type 3. The mean age at diagnosis in type 1 was 28.7 years. A total of 72.7% were classified as having mild forms, 25.5% moderate, and 1.7% severe. Anemia and thrombocytopenia were present in 56% and 55%, respectively. Bone disease and hepatomegaly were reported in 62% and 68%, respectively, and were more likely in asplenic than in non-splenectomized patients. Sixty-nine mutant alleles were identified, and five mutations accounted for 75% of the GBA alleles. Several patients described in our series had interesting phenotypes. A total of 58.7% of patients had received enzyme replacement therapy and 12.6% were treated with miglustat. Conclusions A broad spectrum of GBA mutations is present in the IP, with 98.2% of type 1 GD being mild and 23.0% never treated. These data highlight genetic and phenotypic heterogeneities among geographic populations.

    Full Text Available Abstract Background Compelled by the intuitive appeal of predicting each individual patient’s risk of an outcome, there is a growing interest in risk prediction models. While the statistical methods used to build prediction models are increasingly well understood, the literature offers little insight to researchers seeking to gauge a priori whether a prediction model is likely to perform well for their particular research question. The objective of this study was to inform the development of new risk prediction models by evaluating model performance under a wide range of predictor characteristics. Methods Data from all births to overweight or obese women in British Columbia, Canada from 2004 to 2012 (n = 75,225 were used to build a risk prediction model for preeclampsia. The data were then augmented with simulated predictors of the outcome with pre-set prevalence values and univariable odds ratios. We built 120 risk prediction models that included known demographic and clinical predictors, and one, three, or five of the simulated variables. Finally, we evaluated standard model performance criteria (discrimination, risk stratification capacity, calibration, and Nagelkerke’s r2 for each model. Results Findings from our models built with simulated predictors demonstrated the predictor characteristics required for a risk prediction model to adequately discriminate cases from non-cases and to adequately classify patients into clinically distinct risk groups. Several predictor characteristics can yield well performing risk prediction models; however, these characteristics are not typical of predictor-outcome relationships in many population-based or clinical data sets. Novel predictors must be both strongly associated with the outcome and prevalent in the population to be useful for clinical prediction modeling (e.g., one predictor with prevalence ≥20 % and odds ratio ≥8, or 3 predictors with prevalence ≥10 % and odds ratios ≥4.

    Full Text Available Objectives: To evaluate the relationship between symptoms, clinical severity, neurophysiological characteristics with median nerve cross-sectional area (CSA at the level of carpal tunnel inlet at ultrasonography (USG and its utility in diagnosis of carpal tunnel syndrome (CTS. Materials and Methods: Prospective study of 30 patients with symptoms of CTS, attending to the Neurology out patient department (OPD at University Teaching Hospital. A multidimensional assessment of CTS was done using historic and objective scale (Hi-Ob scale for clinical severity, Boston carpal tunnel questionnaire (BCTQ for patient-oriented measures, neuro physiologic studies of median nerve at wrist and USG to measure median nerve CSA at carpal tunnel inlet. Results: Thirty patients included in the study (22 women and 8 men. Mean of CSA was 12.69 mm 2 (SD2.67. Association between BCTQ score value and inlet values was assessed by Karl Pearson correlation coefficient ( r = 0.376, P = 0.04. There was positive association with BCTQ scores and CSA of median nerve at carpal tunnel inlet. To compare clinical severity scale (Hi-Ob and USG CSA, analysis of variance was performed (F value and Scheffe′s multiple comparison test was used to find group difference (grades 1 and 2 P < 0.001, grades1 and 2P P < 0.001, grade 2 differs with grade 2P P < 0.006. As the number of patients is less in minimal, mild and severe groups, the difference between neurophysiological groups and mean of CSA was not statistically significant. Conclusion: A positive correlation exists between USG findings and all the conventional measures of CTS severity.

    Full Text Available Background: Acne vulgaris is known to impair many aspects of quality of life. However, the correlation of this impairment with clinical severity remains equivocal despite various school, community and hospital-based studies. Aim: A hospital-based study was undertaken to measure the impairment of quality of life of patients of acne vulgaris and correlate it with the severity of lesions. Methods: This was a cross-sectional, questionnaire-based study in a cohort of 100 patients of acne vulgaris attending the outpatient department of our referral hospital. A physician measured the severity of lesions using the global acne grading system, and patients assessed quality of life by completing a questionnaire (Cardiff acne disability index. A correlation of these two was done; some additional correlations were brought out through demographic data collected from the patients. Results: There was no correlation between the severity of acne vulgaris and an impaired quality of life. Patients who consumed alcohol and/or smoked cigarettes were found to have an impaired quality of life. While the severity of acne progressively lessened in older patients, the impact on quality of life increased. Limitations: The sample size was small and there was a lack of guaranteed reliability on the self-reported quality of life. Conclusion: The severity of acne vulgaris does not correlate with impairment in quality of life.

    Zoonotic cutaneous leishmaniasis caused by Leishmania (L.) major parasites affects urban and suburban areas in the center and south of Tunisia where the disease is endemo-epidemic. Several cases were reported in human patients for which infection due to L. major induced lesions with a broad range of severity. However, very little is known about the mechanisms underlying this diversity. Our hypothesis is that parasite genomic variability could, in addition to the host immunological background, contribute to the intra-species clinical variability observed in patients and explain the lesion size differences observed in the experimental model. Based on several epidemiological, in vivo and in vitro experiments, we focused on two clinical isolates showing contrasted severity in patients and BALB/c experimental mice model. We used DNA-seq as a high-throughput technology to facilitate the identification of genetic variants with discriminating potential between both isolates. Our results demonstrate that various levels of heterogeneity could be found between both L. major isolates in terms of chromosome or gene copy number variation (CNV), and that the intra-species divergence could surprisingly be related to single nucleotide polymorphisms (SNPs) and Insertion/Deletion (InDels) events. Interestingly, we particularly focused here on genes affected by both types of variants and correlated them with the observed gene CNV. Whether these differences are sufficient to explain the severity in patients is obviously still open to debate, but we do believe that additional layers of -omic information is needed to complement the genomic screen in order to draw a more complete map of severity determinants.

    Full Text Available Introduction. Secondary lactose intolerance (SLI belongs to the rarer manifestations of gluten-sensitive enteropathy (GSE. It occurs in more severe forms of the disease and its presence contributes significantly to the degree of its expression. Objective. The goal of the study was to determine the frequency of SLI in infants with clinically classic form of GSE, as well as its relationship with the duration, severity and age at the diagnosis of the basic disease and the degree of small bowel mucosa damage. Methods. The study was based on a sample of 42 infants, 30 female and 12 male, aged 7-12 months (x=9.98±1.69, with a clinically classic form of GSE. The diagnosis of GSE was established based on the characteristic pathohistological appearance of small bowel mucosa and clinical improvement of patients on gluten-free diet, while SLI on pathological lactose or milk tolerance test. The assessment of basic disease severity was based on body mass divergence in relation to the standard value, as well as on Hb and serum iron levels, while the degree of small bowel mucosa damage was determined according to the modified Marsh criteria. Results. SLI was verified in 8/42 or 19.05% of patients. In addition to the symptoms and clinical signs of GSE, all the patients with SLI also featured the problems characteristic of lactose tolerance disorders, i.e. watery diarrhoea, borborygmus and meteorism occurring after milk meals. In addition, all had perianal erythema (6 with erosive changes, as well as destructive enteropathy (5 subtotal and 3 total. The difference in the duration of the basic disease, age at diagnosis, as well as in the degree of body mass deviation from the standard value between the lactose-tolerant and lactose-intolerant infants was not found. In addition, no difference in Hb and serum iron levels or in the degree of small bowel mucosa damage was found between the two groups. Conclusion. Our findings indicate that SLI presents a relatively

    Objective: To determine whether the severity of non-neurological critically ill patients correlates with clinical predictors of bronchial aspiration. Methods: We evaluated adults undergoing prolonged orotracheal intubation (> 48 h) and bedside swallowing assessment within the first 48 h after extubation. We collected data regarding the risk of bronchial aspiration performed by a speech-language pathologist, whereas data regarding the functional level of swallowing were collected with the American Speech-Language-Hearing Association National Outcome Measurement System (ASHA NOMS) scale and those regarding health status were collected with the Sequential Organ Failure Assessment (SOFA). Results: The study sample comprised 150 patients. For statistical analyses, the patients were grouped by ASHA NOMS score: ASHA1 (levels 1 and 2), ASHA2 (levels 3 to 5); and ASHA3 (levels 6 and 7). In comparison with the other patients, those in the ASHA3 group were significantly younger, remained intubated for fewer days, and less severe overall clinical health status (SOFA score). The clinical predictors of bronchial aspiration that best characterized the groups were abnormal cervical auscultation findings and cough after swallowing. None of the patients in the ASHA 3 group presented with either of those signs. Conclusions: Critically ill patients 55 years of age or older who undergo prolonged orotracheal intubation (≥ 6 days), have a SOFA score ≥ 5, have a Glasgow Coma Scale score ≤ 14, and present with abnormal cervical auscultation findings or cough after swallowing should be prioritized for a full speech pathology assessment.

    Female genital ulcer is a disease that affects a large number of women, and its etiologic diagnosis can be difficult. The disease may increase the risk of acquiring HIV. Genital ulcer may be present in sexually transmitted diseases (STD)--syphilis, chancroid, genital herpes, donovanosis, lymphogranuloma venereum; and other non-STD disorders (NSTD)--Behçet's syndrome, pemphigus, Crohn's disease, erosive lichen planus and others. This study evaluated the clinical-histopathologic-microbiologic characteristics of female genital ulcers. A cross-sectional descriptive prospective study was conducted during a six-month period to investigate the first 53 women without a definitive diagnosis, seeking medical care for genital ulcers at a genital infections outpatient facility in a university hospital. A detailed and specific history was taken, followed by a dermatologic and gynecologic examination. In addition to collecting material from the lesions for microbiologic study, a biopsy of the ulcer was performed for histopathologic investigation. The average age of the patients was 32.7 years, 56.6% had junior high school education and higher education. The most frequent etiology was herpetic lesion, followed by auto-immune ulcers. At the time of their first consultation, around 60% of the women were using inadequate medication that was inconsistent with the final diagnosis. Histologic diagnosis was conclusive in only 26.4% of the patients (14/53). Cure was obtained in 99% of the cases after proper therapy. The female genital ulcers studied were equally distributed between sexually transmitted and non-sexually transmitted causes. Herpes was the most frequent type of genital ulcer, affecting women indiscriminately, mostly between the ages of 20 and 40 years. The etiologic diagnosis of herpetic ulcers is difficult to make even when various diagnostic methods are applied. It is imperative that NSTD should be included in the differential diagnoses of female genital ulcers. The

    There has been little research examining clinical correlates of childhood-onset pathologic skin picking in a sample of individuals with a primary diagnosis of pathologic skin picking. Using a sample of 40 consecutive subjects with current pathologic skin picking, we compared subjects with childhood-onset (before 10 years of age) pathologic skin picking to those with later onset on a variety of clinical measures. Symptom severity was examined by assessing time spent picking per day, intensity and frequency of thoughts and urges to pick, and social and occupational functioning. Of the 40 subjects, 19 (47.5%) reported onset of skin picking before 10 years of age. Subjects with childhood-onset had significantly longer durations of illness before receiving treatment and were more likely to pick unconsciously. Symptom severity, comorbidity, and social functioning did not differ between groups. These preliminary results suggest that although onset before 10 years of age is fairly common among people with pathologic skin picking, individuals developing this behavior earlier in life have similar clinical characteristics as those with later onset but may be less likely to seek treatment.

    Human severe combined immunodeficiency disease (SCID) includes an X-chromosome-linked type characterized by a complete absence of mature T cells, hypogammaglobulinemia but normal or elevated number of B cells, suggesting that the disease results from a block in early T cell differentiation. It has been shown that B cells from obligate carrier women of this disorder exhibit the preferential use of the nonmutant X chromosome as the active X (as shown for T cells), suggesting that the SCID gene product has a direct effect on B cells as well as on T cells. To examine this question, we analyzed the phenotypic and functional characteristics of peripheral B cells from nine infants with SCID. We found a constant absence of spontaneously expressed activation Ag on B cell membrane from all SCID patients tested which contrasts with the phenotypic pattern exhibited by age-matched infants whom all cells bearing surface Ig express the 4F2 Ag and to a lesser extent the transferrin receptor. Concurrently, B cells from SCID patients have a profound impairment in their responses to stimuli that induce in vitro B cell proliferation and differentiation. Although rIL-2 and low-Mr B cell growth factor are potent inducers of proliferation on age-matched infants' B cells, they are poorly efficient in inducing proliferation of anti-mu-activated SCID B cells. This impairment is not related to the resting B cell phenotype of SCID B cells as shown by comparison with normal resting B cells. Furthermore, we observed an apparent block in B cell differentiation inasmuch as neither rIL-2 nor rIL-6 could support SAC-activated SCID B cell differentiation, both lymphokines being very efficient in inducing SAC-activated age-matched infants' B cell or purified resting B cell differentiation. These results suggest that the SCID gene defect has a direct effect on B cells and is required during B cell maturation.

    Cardiac resynchronization therapy (CRT) improves functional classification among patients with left ventricle malfunction and ventricular electric conduction disorders. However, a high percentage of subjects under CRT (20%–30%) do not show any improvement. Nonetheless the presence of mechanical contraction dyssynchrony in ventricles has been proposed as an indicator of CRT response. This work proposes an automated classification model of severity in ventricular contraction dyssynchrony. The model includes clinical data such as left ventricular ejection fraction (LVEF), QRS and P-R intervals, and the 3 most significant factors extracted from the factor analysis of dynamic structures applied to a set of equilibrium radionuclide angiography images representing the mechanical behavior of cardiac contraction. A control group of 33 normal volunteers (28 ± 5 years, LVEF of 59.7% ± 5.8%) and a HF group of 42 subjects (53.12 ± 15.05 years, LVEF < 35%) were studied. The proposed classifiers had hit rates of 90%, 50%, and 80% to distinguish between absent, mild, and moderate-severe interventricular dyssynchrony, respectively. For intraventricular dyssynchrony, hit rates of 100%, 50%, and 90% were observed distinguishing between absent, mild, and moderate-severe, respectively. These results seem promising in using this automated method for clinical follow-up of patients undergoing CRT.

    Severe malaria is a life-threatening complication of an infection with the protozoan parasite Plasmodium falciparum, which requires immediate treatment. Safety and efficacy concerns with currently used drugs accentuate the need for new chemotherapeutic options against severe malaria. Here we describe a medicinal chemistry program starting from amicarbalide that led to two compounds with optimized pharmacological and antiparasitic properties. SC81458 and the clinical development candidate, SC83288, are fast-acting compounds that can cure a P. falciparum infection in a humanized NOD/SCID mouse model system. Detailed preclinical pharmacokinetic and toxicological studies reveal no observable drawbacks. Ultra-deep sequencing of resistant parasites identifies the sarco/endoplasmic reticulum Ca2+ transporting PfATP6 as a putative determinant of resistance to SC81458 and SC83288. Features, such as fast parasite killing, good safety margin, a potentially novel mode of action and a distinct chemotype support the clinical development of SC83288, as an intravenous application for the treatment of severe malaria.

    The purpose of this paper is to clarify the clinical significance of CT in the diagnosis of severe pelvic fractures. Fifty-six consecutive patients with severe pelvic ring fractures were the subjects of this study. The assessments were as follows: comparison of the diagnostic value of plain X-P and CT for the detection of pelvic fractures, comparison hemodynamic findings before TAE therapy, comparison between abnormal angiographic findings and fracture sites on CT, and comparison between abnormal angiographic findings and volume of retroperitoneal hematomas on CT. CT was more useful for the detection of severe pelvic ring fractures, especially for sacral fracture and iliosacral joint dislocations, than plain X-P. Sacral fracture group was more severe than iliac fracture group on CT. There was a discrepancy between the angiographic findings and fracture sites in 20 of the 56 patients. Angiographic abnormalities without fracture were seen especially in the lateral sacral artery and iliolumbar artery. There was a discrepancy between the angiographic findings and retroperitoneal hematomas in 38 of the 56 patients. Retroperitoneal hematomas, especially around the ilium, were seen on CT in 40 areas in the absence of any abnormal angiographic findings. Conversely, angiographic extravasation without hematoma on CT was seen in 20 areas, especially in lateral sacral artery. CT is useful for detection and intervention in severe pelvic ring fractures.

    Full Text Available Abstract Background Hypophosphatasia (HP is an inborn error of bone metabolism characterized by a genetic defect in the gene encoding the tissue-nonspecific alkaline phosphatase (TNSALP. There is a lack of knowledge as to how the variability and clinical severity of the HP phenotype (especially pain and walking impairment are related to metabolic disturbances or impairments, subsequent to the molecular defect. Methods We analyzed the changes in clinical symptoms and the prostaglandin (PG metabolism in response to treatment with non-steroidal anti-inflammatory drugs (NSAIDs in six children affected by childhood HP. In addition, by exposing HP fibroblasts to pyridoxal phosphate and/or calcium pyrophosphate in vitro, we analyzed whether the alterations in PG levels are sequelae related to the metabolic defect. Results Childhood HP patients, who often complain about pain in the lower limbs without evident fractures, have systemic hyperprostaglandinism. Symptomatic anti-inflammatory treatment with NSAIDs significantly improved pain-associated physical impairment. Calcium pyrophosphate, but not pyridoxal phosphate, induced cyclooxygenase-2 (COX-2 gene expression and PG production in HP and normal fibroblasts in vitro. Conclusion Clinical features of childhood HP related to pain in the lower legs may be, at least in part, sequelae related to elevated PG levels, secondary to the primary metabolic defect. Consequently, NSAID treatment does improve the clinical features of childhood HP.

    Abstract Influenza B viral infection is of great importance, but the epidemiological and phylogenetic characteristics of influenza B infection in severe acute respiratory infection (SARI) cases are still unclear. The clinical information of 2816 SARI cases and 467,737 influenza-like illness (ILI) cases in Beijing area from September 2014 to April 2015 were collected and analyzed. Among them, 91 influenza B viruses isolated from SARI cases were sequenced. The overall yield rate of influenza A/B infection was 14.21% and 27.77% in sampled SARI and ILI cases, respectively. Compared with influenza A infection, the frequency of influenza B infection in SARI cases was higher in younger patients. Phylogenetic analysis suggested that most tested hemagglutination genes belonged to Yamagata lineage Clade 3, which were similar with current circulating viruses but different with 2014 to 2015 influenza season vaccine strain (Clade 2). Importantly, HA-Y3/NA-V4 intralineage reassorting was identified in Beijing area for the first time, which can act as a possible risk factor of SARIs. The influenza activity and virus types/subtypes/lineages among SARI patients were well correlated with that of ILI cases. Furthermore, the potential risk of reassorted influenza B virus infection should not be overlooked. PMID:26717393

    In a 54-year-old male a severe sensory neuropathy was observed during treatment for pulmonary tuberculosis with isoniazid (400 mg/day) and pyridoxine (600 mg/day). Eight months after withdrawal from isoniazid the sensory symptomatology was still progressing, although muscle strength was never reduced. A sural nerve biopsy revealed marked loss of large myelinated fibres. Only when pyridoxine treatment was interrupted did a slow improvement begin. A clinical and electrophysiologic follow-up showed a very slow and still incomplete recovery after four years. The possibility of an unusual individual susceptibility to toxic effects of pyridoxine is considered.

    The fluoropyrimidines are commonly used in chemotherapeutic cancer medicine, but many patients still experience severe adverse side effects from these drugs. We observed a severe toxicity in a 50-year-old woman treated with capecitabine and docetaxel for a metastatic breast cancer. Since dihydropyrimidine dehydrogenase (DPD) is the main candidate for pharmacogenetic studies on 5-FU toxicity, the entire coding sequence and exon-flanking intronic regions of the DPYD gene were sequenced in the patient. None of the previously described deleterious variants were detected. Also, the haplotype-based analysis failed to reveal DPYD variations associated with 5-FU toxicity. We also evaluated the UH2/U ratio in plasma as an index of 5-FU pharmacokinetics. The UH2/U value did not demonstrate low DPD activity in the patient. We discuss the advantages and limitations of this approach, particularly concerning the clinical applications of 5-FU pharmacogenetics in the family setting.

    Full Text Available Severe fever with thrombocytopenia syndrome (SFTS is an emerging infectious and hemorrhagic disease recently described in China and western Japan. A 71-year-old healthy Japanese woman noticed a tick biting her after harvesting in an orchard and removed it herself. She developed diarrhea, anorexia, and chills eight days later. Because these symptoms continued, she visited a primary care physician 6 days after the onset. Laboratory data revealed thrombocytopenia, leukocytopenia, and elevated liver enzymes. She was then referred to our hospital. Although not completely fulfilling the diagnostic criteria used in a retrospective study in Japan, SFTS was suspected, and we detected SFTS virus in the patient’s blood using RT-PCR. However, she recovered without intensive treatment and severe complications 13 days after the onset. In this report, we present a mild clinical course of SFTS virus infection in Japan in detail.

    Full Text Available Objective To investigate the clinical characteristics of patients suffering from acute superior mesenteric venous thrombosis (ASMVT. Methods Clinical data of 96 ASMVT patients admitted to the PLA General Hospital from January 2000 to December 2013 were retrospectively analyzed. Clinical characteristics and death-associated risk factors were studied, and the influence of treatment strategy and thrombosis location on patients' outcome were analyzed. Results The patients were divided into survival group (n=83 and death group (n=13 according to the outcome. The mean age was 46.9 years old, and the ratio of male/female was 3:1. Thirty-nine patients presented isolated superior mesenteric venous thrombosis (SMVT and fiftyseven patients presented combined SMVT. In the death group, higher incidence of severe acute pancreatitis and isolated SMVT were found than the survival group (P<0.01, P=0.004. The patients were again divided into laparotomy group, interventional thrombolysis group, and conservative treatment group according to treatment modality. The interval between symptom onset and treatment was shorter, the incidence of isolated SMVT and mortality rate were higher in the laparotomy group compared with those in interventional thrombolysis group and conservative treatment group. There was no death in the conservative treatment group. In comparison with the combined SMVT group, more patients in the isolated SMVT group presented peritoneal signs and less with history of splenectomy (P<0.001, P=0.002. The proportion of patients with laparotomy and bowel necrosis in the isolated SMVT group was higher than those in the combined SMVT group (P=0.023, P=0.012. Conclusions Patients with isolated SMVT are more likely to have peritoneal signs and bowel necrosis, surgical treatment is mandatory. Patients with combined SMVT often have a history of splenectomy. ASMVT patients with severe pancreatitis may present higher mortality rate. DOI: 10.11855/j

    The molecular intrinsic characteristic contour (MICC) is defined based on the classical turning point of electron movement in a molecule. Three typical organic molecules, I.e. Methane, methanol and formic acid, were employed as examples for detailed introduction of our method. Investigations on the cross-sections of MICC provide important information about atomic size changing in the process of forming molecules. The electron density distributions on the MICCs of these molecules were calculated and shown for the first time. Results showed that the electron density distribution on the MICC correlates closely with molecular chemical properties, and it provides a new insight into molecular boundary.

    The magnetic resonance examination was performed in 38 patients with severe cerebral palsy (CP; 15 males and 23 females) who had both motor delay (unable to move anywhere) and mental retardation (I.Q. or D.Q. below 30). Neuroimaging findings were compared with the CP type, etiology, and grade of understanding of language. Cranial magnetic resonance imagings (MRI) in CP were divided into five types. In type 1, nine predominantly showed cyst-liked ventricles and periventricular hyperintensity on T[sub 2]-weighted imaging (PVH) and only scarred basal ganglia and thalamus were visible. All suffered from neonatal asphyxia and the clinical type was rigospastic tetraplegia (RST). In type 2, eleven predominantly showed PVH and hyperintensity on T[sub 2]-weighted (HT2) in basal ganglia and thalamus. All suffered from neonatal asphyxia and the clinical type was RST or rigospastic diplegia. In type 3, five showed PVH and three had cortical atrophy. All suffered from neonatal asphyxia and the clinical type was spastic diplegia. In type 4, four predominantly showed HT2 in putamen and thalamus. Three had cortical atrophy. All suffered from neonatal asphyxia. The clinical type was athetotic CP (ATH). In type 5, nine predominantly showed HT2 in globus pallidus. Four had cortical atrophy and two had hippocampal atrophy. All suffered from neonatal jaundice and the clinical type was ATH. All patients who suffered from neonatal asphyxia and spastic CP had MRI in PVH. All patients who suffered from neonatal asphyxia and ATH showed HT2 in putamen and thalamus. Almost patients who suffered from neonatal jaundice and ATH showed HT2 in globus pallidus. With athetotic CP, cases with atrophy of the cerebral cortex and/or hippocampus were lower grade of understanding of language than no atrophy of both. The results of studies of MRI are in agreement with neuropathological findings. (author).

    Full Text Available Objective: To assess the direct and indirect costs of diagnosing and treating community-acquired pneumonia (CAP, correlating those costs with CAP severity at diagnosis and identifying the major cost drivers. Methods: This was a prospective cost analysis study using bottom-up costing. Clinical severity and mortality risk were assessed with the pneumonia severity index (PSI and the mental Confusion-Urea-Respiratory rate-Blood pressure-age ≥ 65 years (CURB-65 scale, respectively. The sample comprised 95 inpatients hospitalized for newly diagnosed CAP. The analysis was run from a societal perspective with a time horizon of one year. Results: Expressed as mean ± standard deviation, in Euros, the direct and indirect medical costs per CAP patient were 696 ± 531 and 410 ± 283, respectively, the total per-patient cost therefore being 1,106 ± 657. The combined budget impact of our patient cohort, in Euros, was 105,087 (66,109 and 38,979 in direct and indirect costs, respectively. The major cost drivers, in descending order, were the opportunity cost (lost productivity; diagnosis and treatment of comorbidities; and administration of medications, oxygen, and blood derivatives. The CURB-65 and PSI scores both correlated with the indirect costs of CAP treatment. The PSI score correlated positively with the overall frequency of use of health care services. Neither score showed any clear relationship with the direct costs of CAP treatment. Conclusions: Clinical severity at admission appears to be unrelated to the costs of CAP treatment. This is mostly attributable to unwarranted hospital admission (or unnecessarily long hospital stays in cases of mild pneumonia, as well as to over-prescription of antibiotics. Authorities should strive to improve adherence to guidelines and promote cost-effective prescribing practices among physicians in southeastern Europe.

    Background: Von Hippel–Lindau (VHL) syndrome is a dominantly inherited multisystem cancer syndrome caused by a heterozygous mutation in the VHL tumor suppressor gene. Previous studies suggested that similar populations of Caucasian and Japanese patients have similar genotype or phenotype characteristics. In this comprehensive study of East Asian patients, we investigated the genetic and clinical characteristics of patients with VHL syndrome. Methods: To create a registry of clinical characteristics and mutations reported in East Asian patients with VHL syndrome, we conducted a comprehensive review of English language and non‑English language articles identi‑fied through a literature search. Publications in Japanese or Chinese language were read by native speakers of the language, who then performed the data extraction. Results: Of 237 East Asian patients with VHL syndrome, 154 unique kindreds were identified for analysis. Analyzed by kindred, missense mutations were the most common (40.9%, 63/154), followed by large/complete deletions (32.5%, 50/154) and nonsense mutations (11.7%, 18/154). Compared with a previously reported study of both East Asian and non‑East Asian patients, we found several key differences. First, missense and frameshift mutations in the VHL gene occurred less commonly in our population of East Asian patients (40.9% vs. 52.0%; P = 0.012 and 8.4% vs.13.0%; P < 0.001, respectively). Second, large/complete deletions were more common in our population of East Asian patients (32.5% vs. 10.5%; P < 0.001). Third, phenotypically, we observed that, in our population of East Asian patients with VHL syndrome, the incidence of retinal capillary hemangioblastoma was lower, whereas the incidence of renal cell carcinoma was higher. Conclusions: Evidence suggests that the genotypic and phenotypic characteristics of East Asian patients with VHL syndrome differ from other populations. This should be considered when making screening recommendations for

    Full Text Available Abstract Background Severe malaria is a major contributor of deaths in African children up to five years of age. One valuable tool to support health workers in the management of diseases is clinical practice guidelines (CPGs developed using robust methods. A critical assessment of the World Health Organization (WHO and Kenyan paediatric malaria treatment guidelines with quinine was undertaken, with a focus on the quality of the evidence and transparency of the shift from evidence to recommendations. Methods Systematic reviews of the literature were conducted using the Grading of Recommendations Assessment, Development and Evaluation (GRADE tool to appraise included studies. The findings were used to evaluate the WHO and Kenyan recommendations for the management of severe childhood malaria. Results The WHO 2010 malaria guidance on severe malaria in children, which informed the Kenyan guidelines, only evaluated the evidence on one topic on paediatric care using the GRADE tool. Using the GRADE tool, this work explicitly demonstrated that despite the established use of quinine in the management of paediatric cases of severe malaria for decades, low or very low quality evidence of important outcomes, but not critical outcomes such as mortality, have informed national and international guidance on the paediatric quinine dosing, route of administration and adverse effects. Conclusions Despite the foreseeable shift to artesunate as the primary drug for treatment of severe childhood malaria, the findings reported here reflect that the particulars of quinine therapeutics for the management of severe malaria in African children have historically been a neglected research priority. This work supports the application of the GRADE tool to make transparent recommendations and to inform advocacy efforts for a greater research focus in priority areas in paediatric care in Africa and other low-income settings.

    Full Text Available Tooth wear is attributed to several factors many of which often remain unidentified. Management of tooth wear is challenging in preventive and restorative dentistry. Correct assessment of occlusal vertical dimension, interocclusal rest space, and centric relation records are critical for successful treatment. In order to evaluate different treatment modalities and select the treatment of choice some information can be obtained from study casts and diagnostic wax-up. In order to achieve a predictable and desirable result, a systematic approach may be helpful. This paper describes the full mouth rehabilitation of a 36-year-old bruxer with severely worn dentition and other dental problems such as unfavorable restorations. A diagnostic work-up was performed and provisional restorations were made; then, they were clinically evaluated and adjusted based on the criteria dictating esthetics, phonetics, and vertical dimension. After endodontic therapy, clinical crown lengthening was performed. Two short implants were inserted in the posterior mandible. Custom-cast dowel cores and metal-ceramic restorations were fabricated and a full occlusal splint was used to protect the restorations. We ensured stable contacts on all teeth with equal intensity in centric relation and anterior guidance in accord with functional jaw movements.

    To analyse the patterns of facial nerve canal injury seen at temporal bone computed tomography (CT) in patients with traumatic facial nerve palsy and to correlate these with clinical manifestations and outcome. Thirty cases of temporal bone CT in 29 patients with traumatic facial nerve palsy were analyzed with regard to the patterns of facial nerve canal involvement. The patterns were correlated with clinical grade, the electroneurographic (ENoG) findings, and clinical outcome. For clinical grading, the House-Brackmann scale was used, as follows:grade I-IV, partial palsy group; grade V-VI, complete palsy group. The electroneuronographic findings were categorized as mild to moderate (below 90%) or severe (90% and over) degeneration. In 25 cases, the bony wall of the facial nerve canals was involved directly (direct finding): discontinuity of the bony wall was onted in 22 cases, bony spicules in ten, and bony wall displacement in five. Indirect findings were canal widening in nine cases and adjacent bone fracture in two. In one case, there were no direct or indirect findings. All cases in which there was complete palsy (n=8) showed one or more direct findings including spicules in six, while in the incomplete palsy group (n=22), 17 cases showed direct findings. In the severe degeneration group (n=13), on ENog, 12 cases demonstrated direct findings, including spicules in nine cases. In 24 patients, symptoms of facial palsy showed improvement at follow up evaluation. Four of the five patients in whom symptoms did not improve had spicules. Among ten patients with spicules, five underwent surgery and symptoms improved in four of these; among the five patients not operated on , symptoms did not improve in three. In most patients with facial palsy after temporal bone injury, temporal bone CT revealed direct or indirect facial nerve canal involvement, and in complete palsy or severe degeneration groups, there were direct findings in most cases. We believe that meticulous

    Full Text Available BACKGROUND: Severe malaria (SM is a major cause of death in sub-Saharan Africa. Identification of both specific and sensitive clinical features to predict death is needed to improve clinical management. METHODS: A 13-year observational study was conducted from 1997 through 2009 of 2,901 children with SM enrolled at the Royal Victoria Teaching Hospital in The Gambia to identify sensitive and specific predictors of poor outcome in Gambian children with severe malaria between the ages 4 months to 14 years. We have measured the sensitivity and specificity of clinical features that predict death or development of neurological sequelae. FINDINGS: Impaired consciousness (odds ratio {OR} 4.4 [95% confidence interval {CI}, 2.7-7.3], respiratory distress (OR 2.4 [95%CI, 1.7-3.2], hypoglycemia (OR 1.7 [95%CI, 1.2-2.3], jaundice (OR 1.9 [95%CI, 1.2-2.9] and renal failure (OR 11.1 [95%CI, 3.3-36.5] were independently associated with death in children with SM. The clinical features that showed the highest sensitivity and specificity to predict death were respiratory distress (area under the curve 0.63 [95%CI, 0.60-0.65] and impaired consciousness (AUC 0.61[95%CI, 0.59-0.63], which were comparable to the ability of hyperlactatemia (blood lactate>5 mM to predict death (AUC 0.64 [95%CI, 0.55-0.72]. A Blantyre coma score (BCS of 2 or less had a sensitivity of 74% and specificity of 67% to predict death (AUC 0.70 [95% C.I. 0.68-0.72], and sensitivity and specificity of 74% and 69%, respectively to predict development of neurological sequelae (AUC 0.72 [95% CI, 0.67-0.76].The specificity of this BCS threshold to identify children at risk of dying improved in children less than 3 years of age (AUC 0.74, [95% C.I 0.71-0.76]. CONCLUSION: The BCS is a quantitative predictor of death. A BCS of 2 or less is the most sensitive and specific clinical feature to predict death or development of neurological sequelae in children with SM.

    Full Text Available Background. In recent years, there has been an explosion in the number of technical and medical diagnostic platforms being developed. This has greatly improved our ability to more accurately, and more comprehensively, explore and characterize human biological systems on the individual level. Large quantities of biomedical data are now being generated and archived in many separate research and clinical activities, but there exists a paucity of studies that integrate the areas of clinical neuropsychiatry, personal genomics and brain-machine interfaces.Methods. A single person with severe mental illness was implanted with the Medtronic Reclaim® Deep Brain Stimulation (DBS Therapy device for Obsessive Compulsive Disorder (OCD, targeting his nucleus accumbens/anterior limb of the internal capsule. Programming of the device and psychiatric assessments occurred in an outpatient setting for over two years. His genome was sequenced and variants were detected in the Illumina Whole Genome Sequencing Clinical Laboratory Improvement Amendments (CLIA-certified laboratory.Results. We report here the detailed phenotypic characterization, clinical-grade whole genome sequencing (WGS, and two-year outcome of a man with severe OCD treated with DBS. Since implantation, this man has reported steady improvement, highlighted by a steady decline in his Yale-Brown Obsessive Compulsive Scale (YBOCS score from ∼38 to a score of ∼25. A rechargeable Activa RC neurostimulator battery has been of major benefit in terms of facilitating a degree of stability and control over the stimulation. His psychiatric symptoms reliably worsen within hours of the battery becoming depleted, thus providing confirmatory evidence for the efficacy of DBS for OCD in this person. WGS revealed that he is a heterozygote for the p.Val66Met variant in BDNF, encoding a member of the nerve growth factor family, and which has been found to predispose carriers to various psychiatric illnesses.

    Functional properties of the brain may be associated with changes in complex brain networks. However, little is known about how properties of large-scale functional brain networks may be altered stepwise in patients with disturbance of consciousness, e.g., an encephalopathy. We used resting-state fMRI data on patients suffering from various degrees of hepatic encephalopathy (HE) to explore how topological and spatial network properties of functional brain networks changed at different cognitive and consciousness states. Severity of HE was measured clinically and by neuropsychological tests. Fifty-eight non-alcoholic liver cirrhosis patients and 62 normal controls were studied. Patients were subdivided into liver cirrhosis with no outstanding HE (NoHE, n=23), minimal HE with cognitive impairment only detectable by neuropsychological tests (MHE, n=28), and clinically overt HE (OHE, n=7). From the earliest stage, the NoHE, functional brain networks were progressively more random, less clustered, and less modular. Since the intermediate stage (MHE), increased ammonia level was accompanied by concomitant exponential decay of mean connectivity strength, especially in the primary cortical areas and midline brain structures. Finally, at the OHE stage, there were radical reorganization of the topological centrality-i.e., the relative importance-of the hubs and reorientation of functional connections between nodes. In summary, this study illustrated progressively greater abnormalities in functional brain network organization in patients with clinical and biochemical evidence of more severe hepatic encephalopathy. The early-than-expected brain network dysfunction in cirrhotic patients suggests that brain functional connectivity and network analysis may provide useful and complementary biomarkers for more aggressive and earlier intervention of hepatic encephalopathy. Moreover, the stepwise deterioration of functional brain networks in HE patients may suggest that hierarchical

    Pancreatitis is a rare, life-threatening complication of systemic lupus erythematosus (SLE). This study aimed to describe the clinical features of acute pancreatitis (AP) and chronic pancreatitis (CP) in patients with SLE. Data of patients who fulfilled the revised criteria of the American Rheumatism Association for diagnosis of SLE were retrospectively analyzed. SLE activity was graded according to the SLE Disease Activity Index. Logistic regression analysis was conducted to find out independent associations. Survival rates were estimated by using Kaplan-Meier plots. This study included 5665 SLE patients admitted between January 1983 and January 2014, of whom 52 patients were diagnosed with pancreatitis. Pancreatitis prevalence in SLE patients was 0.92 % (52/5665). AP (0.8 %, 46/5665) was more prevalent than CP (0.1 %, 6/5665), presented mostly during active SLE, and affected more organs. Hypertriglyceridemia occurred in 76.9 % of AP patients and in none of the CP patients. AP patients were divided into severe (n = 10) or mild (n = 20) cases. The average triglyceride level in severe AP cases was higher than that in mild AP cases (P = 0.006), and the mortality rate of lupus-associated AP was 32.6 % (15/46). Concomitant infections and thrombocytopenia were independently associated with poor prognosis (P < 0.001, P = 0.028, respectively). There were significant differences in the clinical manifestations of AP and CP. Patients with severe AP were found to have a higher incidence of concomitant infection and serum triglyceride levels. Concomitant infections and thrombocytopenia were independent risk factors for poor prognosis.

    Background Clostridium difficile is a leading infectious cause of health care associated diarrhoea. Several industrialised countries have reported increased C. difficile infections and outbreaks, which have been attributed to the emergent PCR ribotype 027 strain. Methods and Findings We conducted a case-case study to compare severity of C. difficile disease for patients with 027 versus non-027 ribotypes. We retrospectively collected clinical information about 123/136 patients with C. difficile infections admitted to hospitals in the East of England region in 2006 and from whom stool isolates were cultured and ribotyped as part of an earlier national survey. We defined severe C. difficile disease as having one or more of shock, paralytic ileus, pseudo membranous colitis or toxic megacolon. Patient median age was 83 years old (range 3 to 98, interquartile range 75 to 89), 86% were prescribed antibiotics in the eight weeks before illness onset, 41% had ribotype 027 and 30-day all cause mortality during hospital admission was 21%. Severe disease occurred in 24% (95%CI 13% to 37%) and 17% (95%CI 9% to 27%) of patients with PCR ribotype 027 and non-027 ribotypes respectively. In a multivariable model, ribotype 027 was not associated with severe disease after adjusting for sex, discharge from hospital prior to 60 days of current admission, gastroenteritis on admission, number of initiator antibiotics for C. difficile disease, and hospital where the patient was admitted. Conclusions Our study found no evidence to support previous assertions that ribotype 027 is more virulent than other PCR ribotypes. This finding raises questions about the contribution of this strain to the recent increase in C. difficile disease throughout North America and Europe. PMID:18350149

    AIM: To explore the value of fecal lactoferrin in predicting and monitoring the clinical severity of infectious diarrhea.``METHODS: Patients with acute infectious diarrhea ranging from 3 mo to 10 years in age were enrolled, and one to three stool samples from each subject were collected. Certain parameters, including white blood cells/differential count, C-reactive protein, fecal mucus, fecal pus cells, duration of fever, vomiting, diarrhea and severity (indicated by Clark and Vesikari scores), were recorded and analyzed. Fecal lactoferrin was determined by enzyme-linked immunosorbent assay and compared in different pathogen and disease activity. Generalized estimating equations (GEE) were also used for analysis.``RESULTS: Data included 226 evaluations for 117 individuals across three differenttime points. Fecal lactoferrin was higher in patients with Salmonella (11.17 )j,g/g ± 2.73 μg/g) or Campyhbacter (10.32 μg/g ± 2.94 μig/g) infections and lower in patients with rotavirus (2.82 μg/g ± 1.27 μg/g) or norovirus (3.16 μg/g ± 1.18 |ag/g) infections. Concentrations of fecal lactoferrin were significantly elevated in patients with severe (11.32 μg/g ± 3.29 μag/g) or moderate (3.77 μg/g ± 2.08 μg/g) disease activity compared with subjects with mild (1.51 yig/g ± 1.36 μg/g) disease activity (P < 0.05). GEE analysis suggests that this marker could be used to monitor the severity and course of gastrointestinal infections and may provide information for disease management.``CONCLUSION: Fecal lactoferrin increased during bacterial infection and with greater disease severity and may be a good marker for predicting and monitoring intestinal inflammation in children with infectious diarrhea.

    Full Text Available Background & objectives: Recently there were reports from all over India about changing spectrumof clinical presentation of severe malaria. The present study was planned to study the same in thenorthwest India.Methods: This prospective study was conducted on patients of severe malaria admitted in a classifiedmalaria ward of a tertiary care hospital in Bikaner, Rajasthan (northwest India during 1994 and 2001.It included adult patients of both sexes belonging to all age groups. The diagnosis of Plasmodiumfalciparum was confirmed by demonstrating asexual form of parasites in peripheral blood smear. Allpatients were treated with i.v./oral quinine. The specific complications were treated by standard WHOprotocol. The data for individual complications for both the years were analysed by applying chisquaretest.Results: In a prospective study in 1994 the spectrum of complication was dominated by cerebralmalaria (25.75% followed by jaundice (11.47%, bleeding tendencies (9.59%, severe anaemia(5.83%, shock (5.26%, Acute respiratory distress syndrome—ARDS (3.01%, renal failure (2.07%and hypoglycemia (2.07% whereas in 2001 it was dominated by jaundice (58.85% followed bysevere anaemia (26.04%, bleeding tendencies (25.52%, shock (10.94%, cerebral malaria (10.94%,renal failure (6.25%, ARDS (2.08% and hypoglycemia (1.56%. The sharp difference for presence ofjaundice and severe anaemia in 2001 and cerebral malaria in 1994 was statistically significant. Similarly,the important cause of mortality in 2001 was multiple organ dysfunction syndrome (71.10% withpredominant presentation of jaundice and renal failure, whereas in 1994, it was cerebral malaria (77.96%.Interpretation & conclusion: The observation of changing spectrum of severe malaria in this studyand a significant increase in presentation with jaundice as an important manifestation is highly essentialfor primary, secondary and tertiary level health care providers for proper diagnosis and management.

    The Sporothrix complex members cause sporotrichosis, a subcutaneous mycosis with a wide spectrum of clinical manifestations. Several specific phenotypic characteristics are associated with virulence in many fungi, but studies in this field involving the Sporothrix complex species are scarce. Melanization, thermotolerance, and production of proteases, catalase, and urease were investigated in 61 S. brasiliensis, one S. globosa, and 10 S. schenckii strains. The S. brasiliensis strains showed a higher expression of melanin and urease compared with S. schenckii. These two species, however, presented similar thermotolerances. Our S. globosa strain had low expression of all studied virulence factors. The relationship between these phenotypes and clinical aspects of sporotrichosis was also evaluated. Strains isolated from patients with spontaneous regression of infection were heavily melanized and produced high urease levels. Melanin was also related to dissemination of internal organs and protease production was associated with HIV-coinfection. A murine sporotrichosis model showed that a S. brasiliensis strain with high expression of virulence factors was able to disseminate and yield a high fungal burden in comparison with a control S. schenckii strain. Our results show that virulence-related phenotypes are variably expressed within the Sporothrix complex species and might be involved in clinical aspects of sporotrichosis. PMID:25961005

    Full Text Available Objective: To evaluate the clinical and immunological features of the hemorrhagic fever with renal syndrome in women of different age groups. Materials and methods: Clinical and laboratory characteristics of hemorrhagic fever with renal syndrome in 148 women aged 17 to 65 years old have been investigated. Patients have been divided into two groups: group I included 101 patients with normal menstrual rhythm, group II included 47 female patients with menopause. In 57 women (36 from group I, 21 — from group II the content of CD3+, CD4+, CD8+, CD16+, CD19+ — sub-populations of peripheral blood lymphocytes has been determined. Results: In compared groups significant differences in structure and frequency of complications of the disease have been revealed. Unidirectional tendency to increase significantly reduced absolute rates of investigated lymphocyte subpopulations in dynamics of the disease has been identified. It also has been stated that by the time of early convalescence in case of severe form of HFRS the indices did not reach the standard level. In an older group of women deeper damage and long-term recovery of immune system have been marked. Conclusion: According to the results of clinical and immunological studies the research work has revealed that in young women the response of the immune system to HFRS has developed faster and stronger than that in patients during the menopause period.

    2011-11-01

    Leadership has been consistently implied in fostering clinical learning. However there is a lack of clarity about the form leadership should take. Limited quantitative research indicated a narrative approach to review literature from a broad perspective. A framework to guide the synthesis was developed to ensure a rigorous review process. Preliminary reading and review of papers using search terms nursing and leadership and clinical learning and learning culture narrowed the inclusion criteria to 245 papers published between 2000 and 2010. Given the diversity of the papers' focus, aim and context, a refined screening process justified the inclusion of twenty-six papers in the review. A critical appraisal of these peer-reviewed quantitative, qualitative and commentary papers identified factors/elements integral to effective leadership. Across the literature leadership was discussed in relation to two broad themes: influence of leadership on organisational learning and development and; influence of leadership on undergraduate clinical education. The factors central to leadership emerged as transformative principles, the role of the nurse unit/ward manager, collaboration and relationship building and role-modelling. The review has raised some suggestions for future research aimed at examining the impact of a leadership capacity building intervention that supports clinical learning.

    Full Text Available Abstract Background A waterborne outbreak of Giardia lamblia gastroenteritis led to a high prevalance of long-lasting fatigue and abdominal symptoms. The aim was to describe the clinical characteristics, disability and employmentloss in a case series of patients with Chronic Fatigue Syndrome (CFS after the infection. Methods Patients who reported persistent fatigue, lowered functional capacity and sickness leave or delayed education after a large community outbreak of giardiasis enteritis in the city of Bergen, Norway were evaluated with the established Centers for Disease Control and Prevention criteria for CFS. Fatigue was self-rated by the Fatigue Severity Scale (FSS. Physical and mental health status and functional impairment was measured by the Medical Outcome Severity Scale-short Form-36 (SF-36. The Hospital Anxiety and Depression Scale (HADS was used to measure co-morbid anxiety and depression. Inability to work or study because of fatigue was determined by sickness absence certified by a doctor. Results A total of 58 (60% out of 96 patients with long-lasting post-infectious fatigue after laboratory confirmed giardiasis were diagnosed with CFS. In all, 1262 patients had laboratory confirmed giardiasis. At the time of referral (mean illness duration 2.7 years 16% reported improvement, 28% reported no change, and 57% reported progressive course with gradual worsening. Mean FSS score was 6.6. A distinctive pattern of impairment was documented with the SF-36. The physical functioning, vitality (energy/fatigue and social functioning were especially reduced. Long-term sickness absence from studies and work was noted in all patients. Conclusion After giardiasis enteritis at least 5% developed clinical characteristics and functional impairment comparable to previously described post-infectious fatigue syndrome.

    This review covers the main principles of the Lund concept for treatment of severe traumatic brain injury. This is followed by a description of results of clinical studies in which this therapy or a modified version of the therapy has been used. Unlike other guidelines, which are based on meta-analytical approaches, important components of the Lund concept are based on physiological mechanisms for regulation of brain volume and brain perfusion and to reduce transcapillary plasma leakage and the need for plasma volume expanders. There have been nine non-randomized and two randomized outcome studies with the Lund concept or modified versions of the concept. The non-randomized studies indicated that the Lund concept is beneficial for outcome. The two randomized studies were small but showed better outcome in the groups of patients treated according to the modified principles of the Lund concept than in the groups given a more conventional treatment.

    The objective is to clarify the early clinical characteristics in childhood moyamoya disease (MD). Epidemiologic characteristics, symptoms and diagnostic rates were assessed in 64 children (0-18 years) with definite MD according to developmental stage: infancy (5; 0-1 years); toddlerhood/preschool age (22; 2-5 years); school age (29; 6-10 years); and adolescence (8; 11-18 years). The median ages at onset was 6.25 years and the female to male ratio was 1.9 (~2.5 in toddlerhood/preschool age and in adolescence, P=0.71). Previous headache was observed in 23% (14/64): frequently in school age (38%, P=0.02) and within 6 months before main symptoms (6/11). As an initial symptom, weakness was observed in 78% (50/64) mainly as transient ischemic attack (TIA, 61%) in limbs (90%) and unilaterally (82%). TIA was less frequent in infancy (40%, P=0.04). Seizure was observed in 27% (17/64): frequently in infancy (100%, Pchildren ~5 years (P<0.01). Severe headache associated with MD was observed in 14% (9/64). Provoking events were positive in 42% (27/64): in school age, frequently during eating (28%); and in toddlerhood/preschool age, during crying (27%). The diagnostic rates at 3 and 12 months from symptom-onset were 39% (80% during infancy vs. 28% in school age, P=0.14) and 67%, respectively. Symptomatic progression at diagnosis was observed in 38% (24/64). Initial clinical characteristics in childhood definite MD differed according to developmental stage and from at diagnosis.

    Accurate documentation of disease severity is a prerequisite for clinical research and the practice of evidence-based medicine. The quantification of skin diseases such as psoriasis currently relies heavily on clinical scores. Although these clinical scoring methods are well established and very useful in quantifying disease severity, they require an extensive clinical experience and carry a risk of subjectivity. We explore the opportunity to use in vivo near-infrared (NIR) spectra as an objective and noninvasive method for local disease severity assessment in 31 psoriasis patients in whom selected plaques were scored clinically. A partial least squares (PLS) regression model was used to analyze and predict the severity scores on the NIR spectra of psoriatic and uninvolved skin. The correlation between predicted and clinically assigned scores was R=0.94 (RMSE=0.96), suggesting that in vivo NIR provides accurate clinical quantification of psoriatic plaques. Hence, NIR may be a practical solution to clinical severity assessment of psoriasis, providing a continuous, linear, numerical value of severity.

    Full Text Available Abstract Background Prevalence of pain as a recurrent symptom in children is known to be high, but little is known about children with high impairment from chronic pain seeking specialized treatment. The purpose of this study was the precise description of children with high impairment from chronic pain referred to the German Paediatric Pain Centre over a 5-year period. Methods Demographic variables, pain characteristics and psychometric measures were assessed at the first evaluation. Subgroup analysis for sex, age and pain location was conducted and multivariate logistic regression applied to identify parameters associated with extremely high impairment. Results The retrospective study consisted of 2249 children assessed at the first evaluation. Tension type headache (48%, migraine (43% and functional abdominal pain (11% were the most common diagnoses with a high rate of co-occurrence; 18% had some form of musculoskeletal pain disease. Irrespective of pain location, chronic pain disorder with somatic and psychological factors was diagnosed frequently (43%. 55% of the children suffered from more than one distinct pain diagnosis. Clinically significant depression and general anxiety scores were expressed by 24% and 19% of the patients, respectively. Girls over the age of 13 were more likely to seek tertiary treatment compared to boys. Nearly half of children suffered from daily or constant pain with a mean pain value of 6/10. Extremely high pain-related impairment, operationalized as a comprehensive measure of pain duration, frequency, intensity, pain-related school absence and disability, was associated with older age, multiple locations of pain, increased depression and prior hospital stays. 43% of the children taking analgesics had no indication for pharmacological treatment. Conclusion Children with chronic pain are a diagnostic and therapeutic challenge as they often have two or more different pain diagnoses, are prone to misuse of

    Full Text Available Objective. To determine anxiety and depression levels in adolescents with acne vulgaris in relation to clinical severity and gender. Patients and methods. Using a sectional study, the anxiety and depression level was analyzed of 90 adolescents of both sexes, aged 16 to 21 years, who were suffering from acne vulgaris. The study was conducted between February 1st 2008 and January 31st 2009 at the Dermatovenerology department of the Cantonal Hospital “Dr. Irfan Ljubijankić”, Bihac. According to the type of efflorescence, its localization and severity of clinical features, respondents were classified in three groups: the first group consisted of adolescents with mild forms of acne, the second group had moderate forms of acne and the third had severe forms of acne. Evaluation of anxiety levels in patients with acne vulgaris was made using STAI questionnaire (Spielberger’s state and trait Anxiety Inventory that consists of 20 questions about the essential characteristics of anxiety as the condition, and the level of depression was determined using the BDS-scale (Back Depression Inventory which consists of 18 items that were used by the respondents to perform self-evaluation of depression level.

    Full Text Available BACKGROUND: In 2009, severe fever with thrombocytopenia syndrome virus (SFTSV was identified as a novel member of the genus phlebovirus in the Bunyaviridae family in China. The detailed clinical features of cases with SFTSV infection have not been well described, and the risk factors for severity among patients and fatality among severe patients remain to be determined. METHODOLOGY/PRINCIPAL FINDINGS: Clinical and laboratory features of 115 hospitalized patients with SFTSV infection during the period from June 2010 to December 2011 in Northeast China were retrospectively reviewed. We assessed the risk factors associated with severity in confirmed cases and fatality in severe cases by multivariate analysis. One hundred and three (89.6% of 115 patients presented with multiple organ dysfunction, and 22 (19.1% of 115 proceeded to the stage of life threatening multiple organ failure. Of the 115 patients, 14 fatalities (12.2% were reported. Multivariate analysis demonstrated that the independent predictors of risk for severity were: albumin ≤ 30 g/l (OR, 8.09; 95% CI, 2.58-25.32, APTT ≥ 66 seconds (OR, 14.28; 95% CI, 3.28-62.24, sodium ≤ 130 mmol/l (OR, 5.44; 95% CI, 1.38-21.40, and presence of neurological manifestations (OR, 7.70; 95% CI, 1.91-31.12. Among patients with severe disease, presence of acute lung injury/acute respiratory distress syndrome (HR, 4.59; 95% CI, 1.48-14.19 and disseminated intravascular coagulation (HR, 4.24; 95% CI, 1.38-13.03 were independently associated with fatality. CONCLUSIONS/SIGNIFICANCE: SFTSV infection may present with more severe symptoms and laboratory abnormalities than hitherto reported. Due to infection with a novel bunyavirus, the patients may sufferer multiple organ dysfunction and die of multiple organ failure. In the clinical assessment of any case of SFTS, independent factors relating to prognosis need to be taken into account by clinicians.

    AIM:To understand the distinct,clinical features of myotonia congenita in China.METHODS:Case reports of myotonia congenita were retrieved from the Chinese Journal Full-text database,dating between 1980 and 2007,and analyzed for clinical characteristics of myotonia congenita. RESULTS:There were 35 published reports and 258 cases about myotonia congenita.Six reports(62 cases)were excluded due to lack of clinical data,imprecise diagnosis,or duplication.Finally,29 published reports and 196 cases(140 males and 56 females)were included in this analysis.About 78.6% of patients were diagnosed with myotonia congenita before the age of 20,and among these, 86.1% were classified as dominant inheritance.Lower and upper extremities were frequently affected with severe symptoms.Eyelids,mouth and lingual muscles,and trunk muscles and cervical muscles were less frequently involved.However,muscles for swallowing,sphincter muscles,and smoothmuscles were not involved.There were no reports of cataracts,cardiac conduction block,or dyscrinism. Myotonia congenita symptoms were induced or aggravated by cold temperatures in 71.9% of the patients and warming-up effect occurred in 95.6% of the patients.Muscle hypertrophy was observed in 69.6% and percussion of muscles in 76.5% of the patients.Myotonia potential or myotonia-likepotential was detected in all patients using electromyography.Muscle fiber swelling or hypertrophy was frequently detected through muscular biopsy.CONCLUSION:Myotonia congenita frequently occurs in males before the age of 20,in particular as the autosomal dominant form of myotonia congenita.Skeletal muscles throughout the body,especially the lower and upper extremities,are involved.However,muscles for swallowing,sphincter muscles, and smooth muscles are not involved.Warming-up effect is the main characteristic of myotonia congenita.

    Sleep disruption is common among hematopoietic cell transplant (HCT) recipients, with over 50% of recipients experiencing sleep disruption pre-transplant, with up to 82% of patients experiencing moderate to severe sleep disruption during hospitalization for transplant and up to 43% after transplant. These rates of sleep disruption are substantially higher than what we see in the general population. Although sleep disruption can be distressing to patients and contribute to diminished quality of life, it is rarely discussed during clinical visits. The goal of the current review is to draw attention to sleep disruption and disorders (ie, insomnia, obstructive sleep apnea, restless legs syndrome) as a clinical problem in HCT in order to facilitate patient education, intervention, and research. We identified 35 observational studies published in the past decade that examined sleep disruption or disorders in HCT. Most studies utilized a single item measure of sleep, had small sample size, and included heterogeneous samples of patients. Six studies of the effects of psychosocial and exercise interventions on sleep in HCT have reported no significant improvements. These results highlight the need for rigorous observational and interventional studies of sleep disruption and disorders in HCT recipients..

    Full Text Available BACKGROUND: Therapy of atopic dermatitis (AD relies on immunosuppression and/or UV irradiation. Here, we assessed clinical efficacy and histopathological alterations induced by blue light-treatment of AD within an observational, non-interventional study. METHODOLOGY/PRINCIPAL FINDINGS: 36 patients with severe, chronic AD resisting long term disease control with local corticosteroids were included. Treatment consisted of one cycle of 5 consecutive blue light-irradiations (28.9 J/cm(2. Patients were instructed to ask for treatment upon disease exacerbation despite interval therapy with topical corticosteroids. The majority of patients noted first improvements after 2-3 cycles. The EASI score was improved by 41% and 54% after 3 and 6 months, respectively (p≤0.005, and p≤0.002. Significant improvement of pruritus, sleep and life quality was noted especially after 6 months. Also, frequency and intensity of disease exacerbations and the usage of topical corticosteroids was reduced. Finally, immunohistochemistry of skin biopsies obtained at baseline and after 5 and 15 days revealed that, unlike UV light, blue light-treatment did not induce Langerhans cell or T cell depletion from skin. CONCLUSIONS/SIGNIFICANCE: Blue light-irradiation may represent a suitable treatment option for AD providing long term control of disease. Future studies with larger patient cohorts within a randomized, placebo-controlled clinical trial are required to confirm this observation.

    Refractory anemia (RA) in myelodysplastic syndromes (MDS) are very heterogeneous diseases regarding their morphology, clinical features and survival. We proposed the new designations 'RA with severe dysplasia (RASD)' and 'RA with minimal dysplasia (RAminiD)'. In our criteria, RASD is considered present if a bone marrow (BM) examination shows Pseudo-Pelger-Huet anomalies of mature neutrophils > or =3% and/or micromegakaryocytes (mMgk) of megakaryocytes > or =10% in RA patients. RAminiD is defined as RA cases other than RASD. After the reclassification of 58 primary RA patients, the group was composed of 45 RAminiD and 13 RASD patients. The blast percentage in the BM and the frequency of cytogenetic abnormalities observed in the RASD patients were intermediate between those in the RAminiD and RAEB patients. The analysis of survival curves revealed differences among the three groups; the RASD patients had lower survival probabilities than those of the RAminiD group, and significantly higher probabilities than those of the RAEB group. (RAminiD vs RASD, P=0.06; RASD vs RAEB, P=0.004.) Our data indicate that in RA patients, RASD is a distinct subset of RA with an unfavorable clinical outcome.

    Enteropathogenic Escherichia coli (EPEC) are diarrhoeagenic E. coli, and are a significant cause of gastrointestinal illness among young children in developing countries. Typical EPEC are identified by the presence of the bundle-forming pilus encoded by a virulence plasmid, which has been linked to an increased severity of illness, while atypical EPEC lack this feature. Comparative genomics of 70 total EPEC from lethal (LI), non-lethal symptomatic (NSI) or asymptomatic (AI) cases of diarrhoeal illness in children enrolled in the Global Enteric Multicenter Study was used to investigate the genomic differences in EPEC isolates obtained from individuals with various clinical outcomes. A comparison of the genomes of isolates from different clinical outcomes identified genes that were significantly more prevalent in EPEC isolates of symptomatic and lethal outcomes than in EPEC isolates of asymptomatic outcomes. These EPEC isolates exhibited previously unappreciated phylogenomic diversity and combinations of virulence factors. These comparative results highlight the diversity of the pathogen, as well as the complexity of the EPEC virulence factor repertoire. PMID:27571975

    Complex I deficiency is the most common biochemical phenotype observed in individuals with mitochondrial disease. With 44 structural subunits and over 10 assembly factors, it is unsurprising that complex I deficiency is associated with clinical and genetic heterogeneity. Massively parallel sequencing (MPS) technologies including custom, targeted gene panels or unbiased whole-exome sequencing (WES) are hugely powerful in identifying the underlying genetic defect in a clinical diagnostic setting, yet many individuals remain without a genetic diagnosis. These individuals might harbor mutations in poorly understood or uncharacterized genes, and their diagnosis relies upon characterization of these orphan genes. Complexome profiling recently identified TMEM126B as a component of the mitochondrial complex I assembly complex alongside proteins ACAD9, ECSIT, NDUFAF1, and TIMMDC1. Here, we describe the clinical, biochemical, and molecular findings in six cases of mitochondrial disease from four unrelated families affected by biallelic (c.635G>T [p.Gly212Val] and/or c.401delA [p.Asn134Ilefs(∗)2]) TMEM126B variants. We provide functional evidence to support the pathogenicity of these TMEM126B variants, including evidence of founder effects for both variants, and establish defects within this gene as a cause of complex I deficiency in association with either pure myopathy in adulthood or, in one individual, a severe multisystem presentation (chronic renal failure and cardiomyopathy) in infancy. Functional experimentation including viral rescue and complexome profiling of subject cell lines has confirmed TMEM126B as the tenth complex I assembly factor associated with human disease and validates the importance of both genome-wide sequencing and proteomic approaches in characterizing disease-associated genes whose physiological roles have been previously undetermined.

    We aimed to examine the potential relationship between season of birth (SOB) and clinical characteristics in Korean patients with unipolar non-psychotic major depressive disorder (MDD). Using data from the Clinical Research Center for Depression (CRESCEND) study in South Korea, 891 MDD patients were divided into two groups, those born in spring/summer (n=457) and those born in autumn/winter (n=434). Measurement tools comprising the Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Brief Psychiatric Rating Scale, Scale for Suicidal Ideation, Clinical Global Impression of severity, Social and Occupation Functional Assessment Scale, WHO Quality of Life assessment instrument-abbreviated version, Alcohol Use Disorder Identification Test, and Temperament and Character Inventory were used to evaluate depression, anxiety, overall symptoms, suicidal ideation, global severity, social function, quality of life, drinking, and temperament and character, respectively. Using independent t-tests for continuous variables and χ² tests for discrete variables, the clinical characteristics of the two groups were compared. MDD patients born in spring/summer were on average younger at onset of first depressive episode (t=2.084, p=0.038), had greater loss of concentration (χ²=4.589, p=0.032), and were more self-directed (t=2.256, p=0.025) than those born in autumn/winter. Clinically, there was a trend for the MDD patients born in spring/summer to display the contradictory characteristics of more severe clinical course and less illness burden; this may have been partly due to a paradoxical effect of the 5-HT system.

    The term minimal hepatic encephalopathy (MHE) refers to the subtle changes in cognitive function, electrophysiological parameters, cerebral neurochemical/neurotransmitter homeostasis, cerebral blood flow, metabolism, and fluid homeostasis that can be observed in patients with cirrhosis who have no clinical evidence of hepatic encephalopathy; the prevalence is as high as 84% in patients with hepatic cirrhosis. This cirrhosis complication is generally not perceived by physician, and diagnosis can only be made by neuropsychological tests and other especial measurements like evoked potentials and image studies like positron emission tomography. Diagnosis of minimal hepatic encephalopathy may have prognostic and therapeutic implications in cirrhotic patients. The present review pretends to explore the clinic, therapeutic, diagnosis and prognostic aspects of this complication.

    Although pneumonia is associated with an increased risk of venous thromboembolism, patients with pulmonary embolism and concomitant pneumonia are uncommon. The aim of the present study was to investigate the clinical features of pulmonary embolism with coexisting pneumonia. We retrospectively compared clinical, radiologic and laboratory parameters between patients with pulmonary embolism and concomitant pneumonia (pneumonia group) and those with unprovoked pulmonary embolism (unprovoked group), and then between the pneumonia group and those with pulmonary infarction (infarction group). Of 794 patients with pulmonary embolism, 36 (5%) had coexisting pneumonia and six (1%) had no provoking factor other than pneumonia. Stroke was significantly more common in the pneumonia group, than either the unprovoked group or the infarction group. In the pneumonia group, fever was significantly more common and serum C-reactive protein levels were significantly higher. By contrast, central pulmonary embolism and right ventricular dilation on computed tomography were significantly less frequent in the pneumonia group. In addition, an adverse outcome due to pulmonary embolism was less common in the pneumonia group than in either of the other two groups. The coexistence of pulmonary embolism and pneumonia is rarely encountered in clinical practice, especially without the presence of other factors that could provoke venous thromboembolism and is commonly associated with stroke. It is characterized by lower incidences of central pulmonary embolism and right ventricular dilation and by a lower rate of adverse outcomes due to pulmonary embolism itself.

Average serum prolactin level was 74.05 ng/mL (SD ± 13.33 ng/mL. 78 % of patients with prolactinoma had serum prolactin level under 70.0 ng/mL. No significant association was found between serum prolactin level and the presence of prolactinoma. Conclusion: Prolactinomas are the main cause of hyperprolactinemia and they are found mostly with slight rise of serum prolactin. Pituitary MRI is recommended in patients with hyperprolactinemia, regardless of their prolactin level.

    Pituitary adenoma is the most common cause of hyperprolactinemia, which is a rare endocrine disorder encountered in pediatric patient care. Epidemiological and clinical information about hyperprolactinemia in childhood and adolescence is limited. Clinical signs of hyperprolactinemia are very heterogeneous. In girls, disturbances in menstrual function and galactorrhea may be seen, whereas in boys, headache, visual disturbances, delayed pubertal development and hypogonadism are often present. Owing to the ease of ordering a serum prolactin measurement, an evidence-based, cost-effective approach to the management of this endocrine disorder is required. Before a diagnosis of hyperprolactinemia is made, drug use, renal insufficiency, hypothyroidism, and parasellar tumors should be excluded. The main objectives of treatment are normalization of prolactin level, adenoma shrinkage, and recovery from clinical signs related to hyperprolactinemia. In patients with microadenoma, invasive or non-invasive macroadenoma, and even in patients with visual field defects, dopamine agonists are the first-line treatment. Surgical treatment is indicated in patients who are unresponsive or intolerant to medical treatment or who have persistent neurological signs. Radiotherapy should be considered as a supportive treatment for patients in whom surgery fails or medical response is not achieved.

    Background Inadequate epidemiologic investigations of the paranasal sinuses malignancies prompted this retrospective study with special emphasis on a major group of 111 tumors. Material and Methods Clinical records of 111 patients with histologically confirmed malignant tumors of the paranasal sinuses were investigated retrospectively from April 2000 to January 2012. Collection of data included demographic information, clinical manifestations, treatment plans, and histopathology of the tumor. Results There were 69 (62.16%) male and 42 (37.83%) female patients (male-to-female ratio of 1.6:1), with a median age of 49±12.2 years (range 21 to 88 years). A high level of occurrence was noticed in the fifth (26.3%) decade of life. The most frequent histological types were squamous cell carcinoma (43.5%) and adenoid cystic carcinoma (19%). Among clinical manifestations, nasal obstruction was the most frequent followed by diplopia, and facial swelling. Fifty three patients (47.74%) were treated with combined approach of surgery and radiation therapy. Conclusions Paranasal sinuses malignancies are rare conditions with nonspecific symptoms which make early diagnosis of the lesions more challenging. The optimal therapeutic protocol for patients suffering from these tumors is still a somewhat controversial entity and requires further studies. Key words:Paranasal sinuses, malignancy, surgery,radiotherapy. PMID:27475693

    This retrospective cohort study investigated the presence of bacteria in respiratory secretions of patients hospitalized with acute respiratory infections and analyzed the impact of viral and bacterial coinfection on severity and the mortality rate. A total of 169 patients with acute respiratory infections were included, viruses and bacteria in respiratory samples were detected using molecular methods. Among all samples, 73.3% and 59.7% were positive for viruses and bacteria, respectively; 45% contained both virus and bacteria. Bacterial coinfection was more frequent in patients infected by community respiratory viruses than influenza A H1N1pdm (83.3% vs. 40.6%). The most frequently bacteria detected were Streptococcus pneumoniae and Haemophilus influenzae. Both species were co-detected in 54 patients and identified alone in 22 and 21 patients, respectively. Overall, there were no significant differences in the period of hospitalization, severity, or mortality rate between patients infected with respiratory viruses alone and those coinfected by viruses and bacteria. The detection of mixed respiratory pathogens is frequent in hospitalized patients with acute respiratory infections, but its impact on the clinical outcome does not appear substantial. However, it should be noted that most of the patients received broad-spectrum antibiotic therapy, which may have contributed to this favorable outcome.

    Full Text Available INTRODUCTION Psoriasis is the dermatological disorder characterized by hyperproliferation and inflammation of the skin. The free radicals produced by oxidative stress leads to oxidation of polyunsaturated fatty acids resulting in the formation of lipid peroxidation products such as malondialdehyde (MDA which is a biomarker of oxidative stress. MATERIALS AND METHODS This was a hospital based case control study which included 50 cases of psoriasis and 50 healthy controls. Serum malondialdehyde was measured by thiobarbituric acid reactivity assay method. For the patients with psoriasis, clinical severity was determined according to Psoriasis Area Severity Index (PASI score. Data analysis was done using SPSS software version 16.0. RESULTS AND DISCUSSION Our results showed levels of MDA were significantly increased (P<0.001 in patients with psoriasis as compared to controls. We found a positive correlation between the serum MDA and PASI score. These results supported the proposal that serum MDA level could be helpful in predicting the prognosis of psoriasis and add further support for the involvement of oxidative stress in the pathogenesis of psoriasis. CONCLUSION Our results indicate that oxidative damage resulting from increased reactive oxygen species production may be involved in the pathogenesis of psoriasis

    Objective:To investigate the high risk factors and methods of prevention and treatment of ovarian hyperstimulation syndrome (OHSS) in assisted reproductive techniques (ART).Methods: Clinical data of 93 cycles of OHSS patients after IVF-ET treatment from Apr. 1989to Oct. 2002 were analyzed retrospectively.Results: (1) A large number of follicles stimulated, luteal phase support with HCG and pregnancy were high risk factors to induce OHSS. (2) Longer disease process, more severe symptoms and more albumins used for treatment of OHSS were commonoy observed in pregnant patients with OHSS compared with non-pregnant ones. (3) Vena dropping human serum albumin is one of the most successful treatment as plasma expanders through restoration of colloid osmotic pressure; paracentesis is necessary for critical OHSS patients with severe ascites and hydrothorax;(4) Occasionally therapeutic abortion of an early gestation may be an only way for lifesaving when all other methods have failed.Conclusions: OHSS is a serious complication of controlled ovarian hyperstimulation. Proper prevention and treatment of OHSS are important for patient safety in ART.

    Spinal muscular atrophy (SMA), a motoneuron disease caused by a deficiency of the survival of motor neuron (SMN) protein, is characterized by motoneuron loss and muscle weakness. It remains unclear whether widespread loss of neuromuscular junctions (NMJs) is involved in SMA pathogenesis. We undertook a systematic examination of NMJ innervation patterns in >20 muscles in the SMNΔ7 SMA mouse model. We found that severe denervation (<50% fully innervated endplates) occurs selectively in many vulnerable axial muscles and several appendicular muscles at the disease end stage. Since these vulnerable muscles were located throughout the body and were comprised of varying muscle fiber types, it is unlikely that muscle location or fiber type determines susceptibility to denervation. Furthermore, we found a similar extent of neurofilament accumulation at NMJs in both vulnerable and resistant muscles before the onset of denervation, suggesting that neurofilament accumulation does not predict subsequent NMJ denervation. Since vulnerable muscles were initially innervated, but later denervated, loss of innervation in SMA may be attributed to defects in synapse maintenance. Finally, we found that denervation was amendable by trichostatin A (TSA) treatment, which increased innervation in clinically relevant muscles in TSA-treated SMNΔ7 mice. Our findings suggest that neuromuscular denervation in vulnerable muscles is a widespread pathology in SMA, and can serve as a preparation for elucidating the biological basis of synapse loss, and for evaluating therapeutic efficacy.

    This study aimed to evaluate the frequency and clinical characteristics of hydroxychloroquine (HCQ) retinopathy in Korean patients with rheumatologic diseases. We retrospectively reviewed medical records of 310 patients taking HCQ. Ophthalmic examinations included spectral-domain optical coherence tomography (SD-OCT), automated visual field test, and fundus autofluorescence. The severity of retinopathy was categorized as early, moderate, or severe, and the location was categorized as parafoveal, pericentral, or mixed pattern. Among 310 patients, 9 patients (2.9%) were diagnosed as HCQ retinopathy. Among the patients with HCQ use ≥ 5 years (n = 174), the frequency was 5.2%. Only 1 (11.1%) of the 9 patients was symptomatic. The mean daily dose per kilogram of real body weight of the 9 patients was 5.6 mg, and only 3 had used 6.5 mg or more. Four of the 9 patients had severe HCQ retinopathy. Six of the 9 patients showed pericentral or mixed pattern of retinal damage. Consequently, the frequency of HCQ retinopathy in Korean patients was not low, especially when administered at a high cumulative dose and for a long duration. Screening of HCQ retinopathy by the recommended guidelines that include SD-OCT seems useful and should be done to detect retinal damage earlier in patients with chronic exposure to HCQ.

    Full Text Available BACKGROUND AND OBJECTIVES: Organophosphorus compound poisoning is the most common medico toxic emergency in India the increase in pesticide use in agriculture has paralleled the increase in the use of these products for deliberate self-warm. Respiratory failure is the most common complication of OP poisoning leading to death. Early recognition and prompt ventilator support may improve survival. Owing to limited availability of resources, all OP poisoning patients are not managed in ICUs in Indian setup. It is therefore important that clinical features and criteria to predict the need for ventilator support be identified at initial examination. Hence this study was undertaken to assess the severity of organophosphorus compound poisoning both clinically by using Peradeniya scoring and by estimating serum choline esterase levels. METHODS: Cross sectional study was done at basaveswar teaching and general hospital attached to MR Medical College. Cases with history of exposure to organophosphorus compound within previous 24 hours were chosen after applying inclusion and exclusion criteria. Patients were evaluated for Peradeniya OP poisoning scale and serum cholinesterase levels for assessment of severity of poisoning. Serum cholinesterase levels and Peradeniya OP poisoning scale were studied to predict the need for ventilator support. The results were analyzed using Chi-square test. STATISTICAL ANALYSIS: It was done using pearson’s chi square test. RESULTS: In this study requirement of ventilator support was seen in 36% of patients. Mortality in our study was 18%. Only 15.6% of patients with mild grade of poisoning according to Peradeniya OP poisoning scale required ventilator support, whereas 84.4% did not require ventilator support. Most of patients with moderate (70.6% and severe poisoning (100% according to Peradeniya OP poisoning scale required ventilator support. 93.7% of patients with serum cholinesterase levels more than 50% did not require

    Objective Mutations in the LMNA gene encoding lamins A and C of the nuclear lamina are a frequent cause of cardiomyopathy accounting for 5–8% of familial dilated cardiomyopathy (DCM). Our aim was to study disease onset, presentation and progression among LMNA mutation carriers. Methods Clinical follow-up data from 27 LMNA mutation carriers and 78 patients with idiopathic DCM without an LMNA mutation were collected. In addition, ECG data were collected and analysed systematically from 20 healthy controls. Results Kaplan-Meier analysis revealed no difference in event-free survival (death, heart transplant, resuscitation and appropriate implantable cardioverter-defibrillator therapy included as events) between LMNA mutation carriers and DCM controls (p=0.5). LMNA mutation carriers presented with atrial fibrillation at a younger age than the DCM controls (47 vs 57 years, p=0.003). Male LMNA mutation carriers presented with clinical manifestations roughly a decade earlier than females. In close follow-up non-sustained ventricular tachycardia was detected in 78% of LMNA mutation carriers. ECG signs of septal remodelling were present in 81% of the LMNA mutation carriers, 21% of the DCM controls and none of the healthy controls giving a high sensitivity and specificity for the standard ECG in distinguishing LMNA mutation carriers from patients with DCM and healthy controls. Conclusions Male LMNA mutation carriers present clinical manifestations at a younger age than females. ECG septal remodelling appears to distinguish LMNA mutation carriers from healthy controls and patients with DCM without LMNA mutations. PMID:28123761

    Cardiomyopathies are diseases of the heart muscle, a term introduced in 1957 to identify a group of myocardial diseases not attributable to coronary artery disease. The definition has since been modified to refer to structural and or functional abnormalities of the myocardium where other known causes of myocardial dysfunction, such as systemic hypertension, valvular disease and ischemic heart disease, have been excluded. In this review, we discuss the pathophysiology, clinical assessment and therapeutic strategies for hypertrophic, dilated and hypertrophic cardiomyopathies, with a particular focus on aspects unique to children.

Characteristic behavioral disturbances in PWS include excessive interest in food, skin picking, difficulty with a change in routine, temper tantrums, obsessive and compulsive behaviors, and mood fluctuations. Individuals with PWS typically have intellectual disabilities (borderline to mild/moderate mental retardation and exhibit a higher overall behavior disturbance compared to individuals with similar intellectual disability. Due to its multisystem disorder, family members, caregivers, physicians, dieticians, and speech-language pathologists all play an important role in the management and treatment of symptoms in an individual with PWS. This article reviews current research on behavior and cognition in PWS and discusses management guidelines for this disorder.Keywords: Prader–Willi syndrome; neurodevelopment, hyperphagia, disability

    The inflammatory response induced by burn injury contributes to increased incidence of infections, sepsis, organ failure, and mortality. Thus, monitoring postburn inflammation is of paramount importance but, so far, there are no reliable biomarkers available to monitor and/or predict infectious complications after burn. As interleukin 8 (IL-8) is a major mediator for inflammatory responses, the aim of our study was to determine whether IL-8 expression can be used to predict postburn sepsis, infections, and mortality. Plasma cytokines, acute-phase proteins, constitutive proteins, and hormones were analyzed during the first 60 days after injury from 468 pediatric burn patients. Demographics and clinical outcome variables (length of stay, infection, sepsis, multiorgan failure [MOF], and mortality) were recorded. A cutoff level for IL-8 was determined using receiver operating characteristic analysis. Statistical significance is set at P Patients were grouped according to their average IL-8 levels relative to this cutoff and stratified into high (H) (n = 133) and low (L) (n = 335) groups. In the L group, regression analysis revealed a significant predictive value of IL-8 to percent of total body surface area burned and incidence of MOF (P inflammatory and acute-phase responses compared with the L group (P burn patients.

    Full Text Available Background: Polycystic ovary syndrome (PCOS is common diagnosis in women presenting with infertility. All the dimensions of PCOS have not been completely explored. Many studies have tried to characterize the exact presentation of the disease. In this study we studied clinical features of PCOS in Indian women to characterize different phenotypes of this syndrome. Prevalence of acanthosis nigricans (AN as surrogate marker of insulin resistance, obesity, hirsutism and hypothyroidism in PCOS women have been simultaneously studied. Materials and Methods: Present work is a non comparative cross-sectional open label study carried out over a period of 18 months in an endocrinology hospital in western Maharashtra, India. Results and Conclusion: Authors conclude that PCOS occurs both in obese and non-obese women; AN and hirsutism occur in equal proportion of patients. AN is correlated with obesity. Hormonal dysfunctions in PCOS manifested together or independently. PCOS women can be sub grouped based on clinical features suggestive of endocrinological malfunctions and can be investigated accordingly for selection of appropriate treatment modalities.

Women’s age, gravity, parity, blood groups, pattern of menstrual cycles, complaints at presentation, fertility, ultrasonographical findings, surgical operations and thyroid function tests were evaluated.There were no significant differences in blood group distribution, gravity, parity and thyroid function test results between the patients and the control subjects (P>0.05. A significant difference was found in the complaints at presentation between two groups (P<0.001. Mentrual cycles irregularity was more frequently found in the patients compared with the controls (57.3% vs. 42.9%, respectively, P=0.009. Although no infertile woman was found in the control group, 8.5% of patients were found to have infertility. The sensitivity of ultrasonography was found to be 97.6%. Except for the existence of higher infertility rate and the menstrual cycles irregularities, no significant difference was found in the clinical and laboratory findings between women with or without uterine leiomyoma. Therefore, physical examination and imaging methods are remained as the most important diagnostic tools for uterine leiomyoma.

    A clinical-electroneuromyographical study of 40 children (32 (80%) of them aged from 12 to 17 years, mean age 13,9+/-1,8 years, and 8 (20%) - from 1 to 8 years, mean age 4,4+/-2,1 years) were studied in the acute period of facial nerve paralysis (FNP). Six (15%) children had FNP in the anamnesis. Among precipitating factors were the cold exposure the day before disease onset (20 (50%) patients), symptoms of flu (13 (32,5%) patients) and psycho-emotional tension (3 (7,5%) patients). No precipitation was noted in 4 (10%) children. The degree of muscle paresis was 81,9+/-7% that corresponded to clinical stages III-IV according to K. Rosler. An electroneuromyographical analysis of motor ortho- and antidromic response to the facial nerve stimulation on the side of paresis and on the contralateral side in patients and controls revealed the presence of proximal axon- and myelinopathy of facial nerve with the involvement of its own motorneurons and brain stem interneurons. The maintenance of wink reflex and F-wave blocks in the period over 3 weeks are prognostically unfavorable factors for restoration of mimic muscle function in the early stage of disease.

A retrospective radiology database search over the last 3 years identified 238 patients with flap tears, of which ultimately 58 with isolated flap tears were included after exclusion of patients with other significant knee internal derangement, severe degenerative change or prior surgery. MR studies of the knee were analyzed by two radiologists. Imaging characteristics were correlated with associated knee abnormalities and clinical findings. Statistical analysis employed linear and logistic regression models. Inter- and intrareader reliability was calculated. The medial meniscus was the most common site of flap tears (52/60, 87 %), with inferior displacement (47/60, 78 %). The degree of tibial cartilage loss had a positive correlation with the visual analog pain scale (p = 0.03). Patients who underwent arthroscopy were younger than those who did not (p = 0.01) and more likely to have a positive clinical McMurray test (p = 0.01). Medially and inferiorly displaced flap tears are the most common tear pattern. Those undergoing arthroscopy are more likely to have positive meniscal signs on clinical examination. A greater degree of cartilage loss involving the tibia on MR imaging was associated with increasing visual analog pain scores. (orig.)

    PAPA syndrome (Pyogenic Arthritis, Pyoderma gangrenosum, and Acne) is an autosomal dominant, hereditary auto-inflammatory disease arising from mutations in the PSTPIP1/CD2BP1 gene on chromosome 15q. These mutations produce a hyper-phosphorylated PSTPIP1 protein and alter its participation in activation of the "inflammasome" involved in interleukin-1 (IL-1β) production. Overproduction of IL-1β is a clear molecular feature of PAPA syndrome. Ongoing research is implicating other biochemical pathways that may be relevant to the distinct pyogenic inflammation of the skin and joints characteristic of this disease. This review summarizes the recent and rapidly accumulating knowledge on these molecular aspects of PAPA syndrome and related disorders.

    This study was aimed to evaluate the efficacy and safety of recombinant humanized thrombopoietin (rhTPO) for treating children with severe immune thrombocytopenia (ITP). A total of 25 patients with severe ITP who accepted rhTPO treatment for 14 days between December, 2009 and November, 2012 in Beijing Children's Hospital was retrospectively analyzed. The results showed that the median platelet counts of all 25 patients increased from the lowest level 4.0×10(9)/L (0×10(9)/L-10×10(9)/L) to the highest level 71×10(9)/L (14×10(9)/L-439×10(9)/L) on median 11 days (range from 3 days to 15 days). After rhTPO discontinuation, the platelet counts of patients gradually decreased. Complete response rate was 44% (11/25), response rate was 32% (8/25), non-response rate was 24% (6/25) and total response rate was 76% (19/25). The platelet count in the patients who showed complete response to rhTPO therapy reached the highest 112×10(9)/L (43×10(9)/L-439×10(9)/L) on median 12 days(range from 7 days to 15 days). The patients showed response to rhTPO treatment on median 4 days (range from 1 days to 11 days). The platelet count decreased gradually after the discontinuation of rhTPO administration but still significantly higher on 28 days than the level before the treatment (P rhTPO treatment showed response to γ-globulin after the discontinuation of rhTPO therapy. 2 patients showed mild clinical adverse reaction. It is concluded that rhTPO is an effective and safe treatment method for children with severe ITP. It will help the patient smoothly through the dangerous period of severe bleeding, but the platelet count decreases gradually after rhTPO discontinuation. Maintenance treatment is needed to consolidate the curative efficacy.

    Full Text Available The objective of this research was to evaluate the effects of tiller age on morphogenic and structural characteristics of guinea grass cv. Mombaca subjected to intermittent stocking and three stubble heights: 30 cm, 50 cm and 50-30 cm. Stubble heights were assigned to experimental units in a completely randomized block design with three replicates. Grazing was performed when canopy intercepted 95% of light incidence. Leaf appearance rate, leaf elongation rate and number of live leaves per tiller were higher in the summer when compared with the winter. Contrarily, stem elongation rate, phyllochron and leaf lifespan were lower in the summer when compared with the winter. During the summer, young tillers had higher leaf appearance and elongation rates when compared with the older ones. Young and mature tillers had the highest values of live leaves per tiller in the summer. There was no difference between summer and winter for the final length of leaf blade between tillers of the same age, except in mature tillers, which had higher final leaf length during the summer. Senescence rate of leaves was higher in young tillers, followed by mature and old tillers. Age of tiller affects morphogenic and structural characteristics of pasture, showing that young tillers have better growth compared with mature and old tillers

    Benign osteoblastoma is a rare, vascular, osteoid-forming bone tumor that occurs even less frequently in the cranial bones. Benign osteoblastoma of the cranium affects women slightly more often than men and typically presents in the first three decades of life. Although clinical presentation can vary depending on location, cranial osteoblastoma usually presents as a painful, non-mobile, subcutaneous mass or swelling. On CT scan, it generally presents as a well-demarcated, mixed lytic and sclerotic lesion, with enlarged diploe, thinning outer and/or inner tables, and varying degrees of calcification. It is hypo to isointense on T1-weighted MRI and has variable presentation on T2-weighted MRI. Gross total resection is the definitive treatment, while subtotal resection is utilized when it is necessary to preserve critical adjacent neurovascular structures.

    A 9-month-old male infant was admitted to our hospital on the second day of cold like syndrome because of high fever, convulsion, coma, and decerebrate rigidity. Serum GOT, GPT, LDH, and CPK were markedly elevated. Serum ammonia was slightly increased, and hypoglycemia was present. The cerebrospinal fluid showed no pleocytosis, normal sugar content, but increased protein. Thus we made a diagnosis of clinical Reye syndrome according to the criteria by Yamashita, et al. A CT on the day of admission showed symmetrical low-density areas in the posterior fossa and the regions of thalamus. Ringed enhancements were seen around the areas of low density in the thalamus on the twenty-second hospital day. We consider that these lesions may represent the infarction due to obstruction of the thalamoperforant arteries caused by cerebral edema in the early stage of the disease.

    Full Text Available BACKGROUND: No comprehensive analysis is available on the viral etiology and clinical characterization among children with severe acute respiratory infection (SARI in China during 2009 H1N1 pandemic and post-pandemic period. METHODS: Cohort of 370 hospitalized children (1 to 72 months with SARI from May 2008 to March 2010 was enrolled in this study. Nasopharyngeal aspirate (NPA specimens were tested by a commercial assay for 18 respiratory viral targets. The viral distribution and its association with clinical character were statistically analyzed. RESULTS: Viral pathogen was detected in 350 (94.29% of children with SARI. Overall, the most popular viruses were: enterovirus/rhinovirus (EV/RV (54.05%, respiratory syncytial virus (RSV (51.08%, human bocavirus (BoCA (33.78%, human parainfluenzaviruse type 3 (PIV3 (15.41%, and adenovirus (ADV (12.97%. Pandemic H1N1 was the dominant influenza virus (IFV but was only detected in 20 (5.41% of children. Moreover, detection rate of RSV and human metapneumovirus (hMPV among suburb participants were significantly higher than that of urban area (P<0.05. Incidence of VSARI among suburb participants was also significant higher, especially among those of 24 to 59 months group (P<0.05. CONCLUSION: Piconaviruses (EV/RV and paramyxoviruses are the most popular viral pathogens among children with SARI in this study. RSV and hMPV significantly increase the risk of SARI, especially in children younger than 24 months. Higher incidence of VSARI and more susceptibilities to RSV and hMPV infections were found in suburban patients.

    Full Text Available Bordetella pertussis testing performed using real-time polymerase chain reaction (RT-PCR is interpreted based on a cycle threshold (Ct value. At Public Health Ontario Laboratories (PHOL, a Ct value <36 is reported as positive, and Ct values ≥36 and <40 are reported as indeterminate. PHOL reported indeterminate results to physicians and public health units until May 2012, after which these results were only reported to physicians. We investigated the association between Ct value and disease symptom and severity to examine the significance of indeterminate results clinically, epidemiologically and for public health reporting. B. pertussis positive and indeterminate RT-PCR results were linked to pertussis cases reported in the provincial Integrated Public Health Information System (iPHIS, using deterministic linkage. Patients with positive RT-PCR results had a lower median age of 10.8 years compared to 12.0 years for patients with indeterminate results (p = 0.24. Hospitalized patients had significantly lower Ct values than non-hospitalized patients (median Ct values of 20.7 vs. 31.6, p<0.001. The proportion of patients reporting the most indicative symptoms of pertussis did not differ between patients with positive vs. indeterminate RT-PCR results. Taking the most indicative symptoms of pertussis as the gold-standard, the positive predictive value of the RT-PCR test was 68.1%. RT-PCR test results should be interpreted in the context of the clinical symptoms, age, vaccination status, prevalence, and other factors. Further information on interpretation of indeterminate RT-PCR results may be needed, and the utility of reporting to public health practitioners should be re-evaluated.

    Full Text Available Background: End-stage hypertrophic cardiomyopathy (HCM is complicated by substantial adverse events. However, few studies have focused on electrocardiographic features and their prognostic values in HCM. This study aimed to evaluate the clinical manifestations and prognostic value of electrocardiography in patients with end-stage HCM. Methods: End-stage HCM patients were enrolled from a total of 1844 consecutive HCM patients from April 2002 to November 2013 at Fuwai Hospital. Clinical data, including medical history, electrocardiography, and echocardiography, were analyzed. Cox hazards regression analysis was used to assess the risk factors for cardiovascular mortality. Results: End-stage HCM was identified in 99 (5.4% patients, averaged at 52 ± 16 years old at entry. Atrial fibrillation was observed in 53 patients and mural thrombus in 19 patients. During 3.9 ± 3.0 years of follow-up, embolic stroke, refractory heart failure, and death or transplantation were observed in 20, 39, and 51 patients, respectively. The incidence of annual mortality was 13.2%. Multivariate Cox hazards regression analysis identified New York Heart Association Class (NYHA III/IV at entry (hazard ratio [HR]: 1.99; 95% confidence interval [CI]: 1.05-3.80; P = 0.036, left bundle branch block (LBBB (HR: 2.80; 95% CI: 1.47-5.31; P = 0.002, and an abnormal Q wave (HR: 2.21; 95% CI: 1.16-4.23; P = 0.016 as independent predictors of cardiovascular death, in accordance with all-cause death and heart failure-related death. Conclusions: LBBB and an abnormal Q wave are risk factors of cardiovascular mortality in end-stage HCM and provide new evidence for early intervention. Susceptibility of end-stage HCM patients to mural thrombus and embolic events warrants further attention.

    @@ Severe acute respiratory syndrome (SARS) is a new acute infectious disease which quickly spreads and develops, resulting in high mortality. Since there lacks any diagnostic method with high specificity and sensitivity, the X-ray chest film becomes an important measure for diagnosis for SARS. Therefore, to understand the characteristics of X-ray chest film in SARS patients and get to know the rule of its dynamic changes is meaningful for SARS diagnosing, treating and prognosing. The characteristics and dynamic changes of chest film in 50 SARS patients in Hebei Province were analysed by the authors and reported as follows.

    Objective To analyze diagnostic approach to severe acute respiratory syndrome (SARS) according to the diagnostic criteria issued by the Ministry of Health of China (MHC). Methods The clinical data and the diagnostic results of 108 cases of SARS were retrospectively reviewed according to the MHC criteria. Results There were 55 men and 53 women, with a median age of 34.5 years (range, 12-78 years). The interval between their first visit and clinical diagnosis was 3 days (range, 0-14 days). The diagnosis was made at the first visit in 7 (6.5%, 7/108) cases with a history of exposure to SARS patients and infiltrates on chest radiograph. Eighty-nine (82.4%) and 12 (11.1%) patients were categorized as probable cases and suspected cases respectively at their first visit and a clinical diagnosis of SARS was made subsequently. The interval between first visit and reaching the final diagnosis was 1-3 days in 72 (66.7%) cases and 4 days in 29 (26.9%) cases. The final diagnosis was made in 0-14 days (median, 2 days) for those (n=59, 54.6%) with a history of close contact with SARS patients and 2-8 days (median, 3 days) for those (n=49, 45.4%) living in Beijing but without such a history (P=0.03). The chest radiograph was interpreted as unremarkable in 26 (24.1%) cases at their first visit, and the diagnosis was made in 4 days (range 2-8 days), which was significantly longer compared with other cases (P<0.001). In patients without a history of close contact with SARS patients, all the five criteria were met after combination antibiotic therapy had failed. Conclusions A chest radiograph without infiltrates at the early stage of SARS is an important factor responsible for delayed diagnosis. In patients without a history of close contact with SARS cases, antibiotic effect was a major factor influencing doctors' diagnosis.

    On 27/28 July, two severe supercell thunderstorms in Germany caused unexpected extreme losses of 3.1 bn EUR(insured) and 4.0 bn EUR(economic), respectively. According to the recently published damage statistics of Munich Re for the year 2013, these hail events were the costliest natural catastrophe in worldwide for that year ranked by insured losses. This example exemplifies the large damage potential related to hail events, which is still underestimated both by the public and the insurance industry. On 27 July, the first supercell moved over the federal states of North Rhine-Westphalia and Lower Saxony. Large hail with diameters of up to 7.5 cm according to observations archived in the European Severe Weather Database (ESWD) caused severe damage especially over the Volkswagen factory in Wolfsburg. One day later, on 28 July, another supercell formed upstream of the Black Forest Mountains and moved almost parallel over the Swabian Jura and Bavaria. Hail with diameters of up to 8 cm fell over a heavily populated region between the cities of Reutlingen and Tübingen. In this area, exposed assets are extremely high, which partly explain the high total loss. Approximately 100,000 buildings and 50,000 automobiles (not considered are the damaged automobiles at the parking lot in Wolfsburg) were severely damaged by these two events. Considering the single event definition over a 72-hr period, which is usually applied in the insurance industry, these hailstorms were one of the most expensive loss events in Germany. In this paper, we investigate the severe hailstorm on 28 July from different views. By using and combining available observational data sets, the objective is to reconstruct the whole events at a very high resolution and to examine the conditions that are most relevant for convective initiation and the further development of the organized convective cell. Using a series of photos of damaged objects the aim is to relate different object classes and hail stone

    Multiple sclerosis can affect pediatric patients. Our aim was to compare characteristics between pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanic Americans. This was a cross-sectional analysis of 363 Hispanic American multiple scleroses cases; demographic and clinical characteristics were analyzed. A total of 110 Hispanic patients presented with multiple sclerosis before age 18 and 253 as adult multiple sclerosis. The most common presenting symptoms for both was optic neuritis. Polyfocal symptoms, seizures, and cognitive symptoms at presentation were more prevalent in pediatric-onset multiple sclerosis (P ≤ .001). Transverse myelitis was more frequent in adult-onset multiple sclerosis (P ≤ .001). Using multivariable analysis, pediatric-onset multiple sclerosis (adjusted odds ratio, 0.3OR 95% confidence interval 0.16-0.71, P = .004) and being US born (adjusted odds ratio, 0.553, 95% confidence interval 0.3-1.03, P = .006) were less likely to have severe ambulatory disability. Results suggest that pediatric-onset multiple sclerosis and adult-onset multiple sclerosis in Hispanics have differences that could be important for treatment and prognosis.

    Full Text Available BACKGROUND Recent advances in pathophysiology and therapeutic measures suggest that patients suffering from acute pancreatitis (AP should undergo an early evaluation and treatment in Internal Medicine wards. Severe AP, usually associated with pancreatic necrosis and peripancreatic fluid collections, may be frequently complicated by distant organ(s involvement. RESULTS The dreadful multi-organ failure may occur as an early event (during the first week of the disease or in association with the infection of pancreatic necrosis in a later stage. So, during the clinical outcome, physicians may be compelled to counteract cardio-circulatory, pulmonary, renal, hepatic, haematological and hydro-electrolytic complex derangements. Arterial hypotension and shock may be consequence of hypovolemia and/or hearth failure or septic shock syndrome. Pleural effusions are frequent in the early phase of the disease as well as pulmonary densifications and renal insufficiency. Urinary, pulmonary, and biliary infections may intervene during all phases of the disease whereas pancreatic necrosis and fluid collections infections are more frequent after the second week of hospitalization. Prognostic evaluation should be obtained by simple and precise scoring system such as the modified Marshall score and CT-scan severity index. CONCLUSIONS Treatment must be initiated as soon as possible with special focusing on fluid and nutritional supplementation, pain control, cardio-respiratory support, antiproteases and antibiotics. Invasive procedures such as endoscopic sphincterotomy in biliary AP with cholangitis and/or obstruction and percutaneous drainage should be utilized in specific cases. Surgical necrosectomy is mandatory in patients with documented infection of pancreatic necrosis.

    Full Text Available BACKGROUND: The severity and longevity of inflammation is controlled by endogenous counter-regulatory signals. Among them are long-chain polyunsaturated fatty acid (PUFA-derived lipid mediators, which promote the resolution of inflammation, an active process for returning to tissue homeostasis. OBJECTIVE: To determine whether endogenous production of lipid-derived resolution agonists is regulated differentially in patients with highly active and less active multiple sclerosis (MS. DESIGN: Matched-pairs study in University hospital Neurology department. PATIENTS: Based on clinical (relapse frequency and paraclinical (MRI lesions, contrast enhancement criteria, 10 pairs of age- and sex-matched patients with relapsing-remitting MS were assigned either to a group with highly active or less active MS. Lipid mediators were quantified in serum and cerebrospinal fluid using LC-MS/MS-based lipidomics. RESULTS: Levels of the key arachidonic (ω-6 and docosahexaenoic acid (ω-6-derived mediators prostaglandins (PG, leukotrienes, hydroxyeicosatetraenoic acids (HETE and resolution agonists lipoxin A(4 (LXA(4, resolvin D1 (RvD1 and neuroprotectin D1 (NPD1 were quantified. In the patient group with highly active MS, 15-HETE and PGE(2 were increased, which are products of the 15-lipoxygenase and cyclooxygenase pathways. The proresolution mediator RvD1 was significantly upregulated and NPD1 was detected in the highly active group only. LXA(4 levels were not increased in patients with highly active MS. CONCLUSIONS: Lipid mediator pathways are regulated differentially in the cerebrospinal fluid of MS patients, depending on disease severity. Non-exhaustive or possibly 'delayed' resolution pathways may suggest a defective resolution program in patients with highly active MS. Longitudinal analyses are required to hetero-typify this differential resolution capacity, which may be associated with disease progression, longevity and eventual termination.

  20. Clinical features and outcome in children with severe Plasmodium falciparum malaria: a meta-analysis.

    Full Text Available BACKGROUND: Although global malaria mortality is declining, estimates may not reflect better inpatient management of severe malaria (SM where reported case fatality rates (CFRs vary from 1-25%. METHODS: A meta-analysis of prospective studies of SM was conducted to examine i whether hypothesized differences between clinical features and outcome in Melanesian compared with African or Asian children really exist, and ii to explore temporal changes in overall and complication-specific CFRs. The proportions of different SM complications and, overall and complication-specific CFRs were incorporated into the meta-analysis. Adjustments were made for study-level covariates including geographic region, SM definition, artemisinin treatment, median age of participants and time period. FINDINGS: Sixty-five studies were included. Substantial heterogeneity (I(2>80% was demonstrated for most outcomes. SM definition contributed to between-study heterogeneity in proportions of cerebral malaria (CM, metabolic acidosis (MA, severe anemia and overall CFR, whilst geographic region was a significant moderator in for CM and hypoglycemia (HG rates. Compared with their African counterparts, Melanesian children had lower rates of HG (10% [CI95 7-13%] versus 1% [0-3%], P<0.05, lower overall CFR (2% [0-4%] versus 7% [6-9%], P<0.05 and lower CM-specific CFR (8% [0-17%] versus 19% [16-21%], P<0.05. There was no temporal trend for overall CFR and CM-specific CFR but declining HG- and MA- specific CFRs were observed. INTERPRETATION: These data highlight that recent estimates of declining global malaria mortality are not replicated by improved outcomes for children hospitalized with SM. Significant geographic differences in the complication rates and subsequent CFRs exist and provide the first robust confirmation of lower CFRs in Melanesian children, perhaps due to less frequent HG.

    Due to the specific physiology associated with pregnancy and puerperium, cerebral venous sinus thrombosis (CVT) may manifest different characteristics. This study aimed to identify the clinical manifestations and prognosis of pregnancy-associated CVT. A total of 43 pregnancy-associated CVT patients were enrolled. We analysed the clinical presentations of the disease and performed a multivariate logistic regression analysis to determine which variables were associated with prognosis. Our descriptive results showed the following: 1) the incidence was 202 per 100,000 deliveries, and the mortality rate was 11.63%; 2) the most frequent symptom was headache; 3) the most frequent abnormal laboratory findings were increased levels of fibrinogen and several serum lipoproteins (including triglyceride, cholesterol, high-density lipoprotein, low-density lipoprotein, apolipoprotein A1, and apolipoprotein B); and 4) the superior sagittal sinus and transverse sinus were the most frequently affected locations. Moreover, an increased modified Rankin Scale score was positively associated with infection, seizure, intracerebral haemorrhage (ICH) and hypertensive disorders of pregnancy (HDP). Comparably, the occurrence of death was positively and significantly associated with infection, seizure and ICH. Consequently, timely diagnosis and treatment of pregnancy-associated CVT patients with infection, seizure, ICH or HDP are needed. Patients with infection, seizure or ICH have a greater risk of death.

    Full Text Available Background: Brucellosis is acute zoonotic, multi-systemic infection caused by Brucella bacteria kind. Brucellosis is met everywhere on all continents of the world, especially in the countries where livestock sector is developed. Nowadays in spite of significant success in the struggle against brucellosis this infection is a social problem. Brucellosis has specific clinical manifestations during various age periods. Problems interrelated with the study of the pathogenesis of brucellosis infection, particularly immune genesis, defining the progress and the outcome of the disease have great importance. Object of the research: to study peculiarities of the progress of acute brucellosis in children taking into account clinical-immunologic data. Materials and methods of the research: the research was based on the results of examinations of 23 children from 3 to 14 years old with brucellosis mostly living in endemic foci of the Republic of Uzbekistan. The diagnosis was defined based on epidemiologic anamnesis, clinical symptoms and laboratory data. All examined children got the analysis of detailed blood immunogramm. The corresponding data of 20 healthy children served to be controlling ones. Results and discussion: The analysis of epidemiologic anamnesis showed, that 78.3% of the examined patients with brucellosis were villagers keeping sheep, goats and cattle. In 73.9% cases source of infection was sheep and goats, 8.7% - cattle, and in 17.4% cases we could observe mixed type of infection. 78% of patients applied to hospital during prodromal period. Main complaints were weakness, frustration, headache, fatigue, bad appetite. These symptoms lasted not more than 3-5 days, after which there were symptoms of intoxication of organism with the rise of cardinal symptoms such as fever with chill (100%, arthalgia (69%, slight sweating (70%, hepato-lienal syndrome (68%. 32.9% of patients had tachycardia.

    Full Text Available Fermentable carbohydrates are an important part of the canine diet. They can improve gastrointestinal health by modifying gut microbial population and metabolic activity. The present study compared the fermentation characteristics and kinetic patterns of 10 carbohydrate sources using the in vitro gas production technique (IVGPT with dog faecal inoculum. The substrates tested were: pure cellulose (PC, carboxymethylcellulose (CMC, sugar-cane fibre (SCF, beet pulp (BP, wheat bran (WB, fructooligosaccharides (FOS, inulin, yeast cell wall (YCW, ground psyllium seed (PS, pea hulls (PH. All substrates were incubated at 39°C under anaerobic conditions with faeces collected from dogs as microbial inoculum. Gas production of fermenting cultures was recorded and after 48 h, pH, short-chain fatty acids (SCFA and organic matter disappearance (OMD were determined. The results confirm high fermentation by dog faecal bacteria of FOS and inulin that produced high amounts of propionate and that underwent very rapid fermentation. Three substrates (SCF, CMC and PC were not able to support bacterial growth, with low gas and SCFA production, and high BCFA formation. PH and BP showed moderate OMD and SCFA production. Wheat bran B underwent rapid fermentation and generated a high proportion of butyrate. PS underwent slow fermentation with delayed gas production, supporting a high formation of SCFA, with an adequate amount of butyrate for bacterial growth while YCW, which showed a delayed fermentation, gave moderate SCFA production. The fermentation characteristics of PS and YCW suggest their potential use in promoting a more distal fermentation on intestinal tract.

A good response group (GRG and a poor response group (PRG were defined if the duration of their seizure-free period was >1 year, or <1 year, respectively.Results: There were 46 (54.8% patients in the GRG and 38 (45.2% patients in the PRG. The number of antiepileptic drugs administered was significantly lower in the GRG than that in the PRG (1.3±0.8 vs 2.8±1.0, respectively; P<0.05. The GRG had a significantly older age of onset than the PRG and a lower occurrence of initial precipitating events, such as febrile seizures, central nervous system infection, and head trauma (P<0.05. The prevalence of EEG abnormality, presence of aura, generalized seizures, and automatism was less frequently observed in the GRG (P<0.05. Multivariate analysis showed that the presence of automatism and initial precipitating events were significantly associated with a poor prognosis (P<0.05.Conclusion: In contrast to the commonly assumed intractability of TLE, we found that more than 54% of patients with TLE-NL achieved a long seizure-free period. Older age at onset of TLE-NL was associated with a better prognosis. However, the presence of automatism and initial precipitating events were related to a poor prognosis. Future prospective

    Hypomorphic mutations in genes associated with severe combined immunodeficiency (SCID) or Omenn syndrome can also cause milder immunodeficiencies. We report 10 new patients with such "atypical" SCID and summarize 63 patients from the literature. The patient groups with T(low)B(low) (n=28), T(low)B(+) (n=16) and ADA (n=29) SCID variants had similar infection profiles but differed in the frequency of immune dysregulation, which was observed predominantly in patients with recombination defects. Most immunological parameters were remarkably similar in the three groups. Of note, 19/68 patients with "atypical" SCID had normal T cell counts, 48/68 had normal IgG and 23/46 had at least one normal specific antibody titer. Elevated IgE was a characteristic feature of ADA deficiency. This overview characterizes "atypical" SCID as a distinct disease with immune dysregulation in addition to infection susceptibility. Lymphopenia, reduced naïve T cells and elevated IgE are suggestive, but not consistent features of the disease.

    Full Text Available We performed a prospective, double-blinded study in 20 patients undergoing gynecologic surgery with lower abdominal incision, to investigate characteristics of intrathecal hyperbaric levobupivacaine compared with isobaric levobupivacaine. We randomly assigned them to receive 3 mL of either isobaric or hyperbaric 0.42% levobupivacaine intrathecally. We found that hyperbaric levobupivacaine, compared with isobaric levobupivacaine, spread faster to T10 level (2.8 ± 1.1 versus 6.6 ± 4.7 minutes, =0.039, reached higher sensory block levels at 5 and 15 minutes after injection (T8 versus L1, =0.011, and T4 versus T7, =0.027, resp., and had a higher peak level (T4 versus T8, =0.040. Isobaric levobupivacaine caused a wider range of peak levels (L1 to C8 compared with hyperbaric form (T7 to T2. The level of T4 or higher reached 90% in the hyperbaric group compared with 20% in the isobaric group (=0.005. Our results suggest that hyperbaric levobupivacaine was more predictable for sensory block level and more effective for surgical procedures with lower abdominal approach. Hyperbaric levobupivacaine seems to be suitable, but the optimal dosage needs further investigation.

    The aim of this analysis was to identify Young Mania Rating Scale (YMRS) meaningful benchmarks for clinicians (severity threshold, minimal clinically significant difference [MCSD]) using the Clinical Global Impressions Bipolar (CGI-BP) mania scale, to provide a clinical perspective to randomized clinical trials (RCTs) results. We used the cohort of patients with acute manic/mixed state of bipolar disorders (N = 3459) included in the European Mania in Bipolar Longitudinal Evaluation of Medication (EMBLEM) study. A receiver-operating characteristic analysis was performed on randomly selected patients to determine the YMRS optimal severity threshold with CGI-BP mania score ≥ "Markedly ill" defining severity. The MCSD (clinically meaningful change in score relative to one point difference in CGI-BP mania for outcome measures) of YMRS, was assessed with a linear regression on baseline data. At baseline, YMRS mean score was 26.4 (±9.9), CGI-BP mania mean score was 4.8 (±1.0) and 61.7% of patients had a score ≥ 5. The optimal YMRS severity threshold of 25 (positive predictive value [PPV] = 83.0%; negative predictive value [NPV] = 66.0%) was determined. In this cohort, a YMRS score of 20 (typical cutoff for RCTs inclusion criteria) corresponds to a PPV of 74.6% and to a NPV of 77.6%, meaning that the majority of patients included would be classified as severely ill. The YMRS minimal clinically significant difference was 6.6 points.

They were divided into two groups according to administration of antihistamines at the onset of fever.Results: Detailed clinical manifestations were compared between patients with and without administration of antihistamines. The time from fever detection to seizure onset was significantly shorter in the antihistamine group than that in the nonantihistamine group, and the duration of seizures was significantly longer in the antihistamine group than in the nonantihistamine group. No significant difference was found in time from fever detection to seizure onset or seizure duration between patients who received a first-generation antihistamine and those who received a second-generation antihistamine.Conclusion: Due to their central nervous system effects, H1 antagonists should not be administered to patients with febrile seizures and epilepsy. Caution should be exercised regarding the use of histamine H1 antagonists in young infants, because these drugs could potentially disturb the anticonvulsive central histaminergic system.Keywords: antihistamine, nonantihistamine, histamine H1 antagonist, febrile seizures

    Tangier disease (TD) (OMIM#205400) is a rare autosomal recessive disorder resulting from mutations in the ABCA1 gene, leading to decreased levels of plasma high-density lipoproteins (HDL). Peripheral neuropathy is a common finding in this disease, and may present as relapsing/remitting mono/polyneuropathies or as syringomyelia-like neuropathy. We retrospectively analyzed four patients, and report here their clinical, biological, electrophysiological, imaging, and genetic findings. Three patients had a typical pseudosyringomyelic neuropathy including facial diplegia, but asymmetrical onset was observed in one patient who had first been misdiagnosed with Lewis-Sumner syndrome. Electrophysiological pattern was heterogeneous, showing both signs of demyelination and axonal degeneration. Truncating mutations of the ABCA1 gene, including two previously undescribed mutations, were constantly found. Atypical symptom onset and demyelinating features on electrophysiological examination can be misleading in case of pseudosyringomyelic neuropathy. These reports illustrate two different neurological phenotypes in TD, namely the pseudosyringomyelic type and the Lewis-Sumner-like type, and advocate for a systematic assessment of lipid profile including HDL cholesterol in demyelinating neuropathies.

    The clinical characteristics of patients with disorders of sex development (DSD), and the diagnostic values of classic cytogenetic and molecular genetic assays for DSD were investigated. In the enrolled 56 cases, there were 9 cases of 46,XY DSD, 6 cases of Turner syndrome (TS), one case of Super female syndrome, 25 cases of Klinefelter syndrome, 14 cases of 46,XX DSD, and one case of autosomal balanced rearrangements with hypospadias. The diagnosis of sex was made through physical examination, cytogenetic assay, ultrasonography, gonadal biopsy and hormonal analysis. PCR was used to detect SRY, ZFX, ZFY, DYZ3 and DYZ1 loci on Y and X chromosomes respectively. The DSD patients with the same category had similar clinical characteristics. The karyotypes in peripheral blood lymphocytes of all patients were identified. PCR-based analysis showed presence or absence of the X/Y-linked loci in several cases. Of the 9 cases of 46,XY DSD, 6 were positive for SRY, 9 for ZFX/ZFY, 9 for DYZ3 and 8 for DYZ1 loci. Of the 6 cases of TS, only 1 case with the karyotype of 45,X,/46,XX/46,XY was positive for all 5 loci. Of the 25 cases of Klinefelter syndrome, all were positive for all 5 loci. In one case of rare Klinefelter syndrome variants azoospermia factor (AZF) gene detection revealed the loss of the AZFa+AZFb region. In 14 cases of 46,XX DSD, 7 cases were positive for SRY, 14 for ZFX, 7 for ZFY, 7 for ZYZ3, and 5 for DYZ1. PCR can complement and also confirm cytogenetic studies in the diagnosis of sex in cases of DSD.

    Purpose To review the current progress in epidemiology, etiology, clinical manifestation, and pathophysiology of severe cutaneous adverse drug reactions(SCADRs). Data sources Data were acquired by using Blackwell-Synergy, PubMed, original articles published in the main Chinese journals and related medical textbooks materials. Study-selection and date extraction Throughout the literature review 49 articles were selected. Results SCADRs cases are rare, however, the implication is life threatening with significant mortatity rates. Epidemiology studies have shown various incidences from different regions, gender, age, race and concurrent illness. There are typical signs and symptoms for each type of SCADRs, but this is not always so. Drugs associated with inducing SCADRs are anticonvulsants, antibiotics, NSAIDs and antirheumatic drugs. In some countries, especially in Asia, traditional drugs are offen the cause of SCADRs. Genetic polymorphisms and viral infections are predisposition factors of SCADRs. Patients with certain genetic alleles and underlying diseases are vulnerable to SCADRs. The exact pathogenesis of SCADRs is not well defined. Nonetheless, recent study showed that reactive metabolites and immunological processes have a significant role in SCADRs. Conclusions The different SCADRs reactions are attributed by different intrinsic factors, such as genetic polymorphisms, gender, age and race as well as extrinsic factors, such as underlying diseases. Different regions and culprit drugs also play a role in the various types of SCADRs.

    Management of antithrombotic therapy in elderly patients with unstable atherothrombotic disease and increased risk of bleeding is a major clinical challenge. We report the case of a 79 year- old diabetic man with rheumatoid arthritis on both oral corticosteroids and NSAID therapy with mild renal dysfunction, who presented to our hospital because of disabling claudication. Prior to admission he had several episodes of TIA. He also had recurrent small rectal bleeding and mild anemia attributed to his long-standing hemorrhoid disease. Angiography showed a sub-occlusive left internal carotid artery stenosis associated with a significant LAD stenosis and complex peripheral artery disease. Cataclysmic bleeding and hemorrhagic shock occurred in the third day post admission. Withdrawal of all antithrombotic treatment, blood transfusion and emergency sigmoidectomy were performed for bleeding colonic diverticulosis. Subsequently antiplatelet therapy was reinitiated and the patient successfully underwent left carotid artery endarterectomy and LAD stenting. He was discharged from hospital on the 21(st) day post admission and is doing well at 24 months follow-up.

    Full Text Available Factors that affect highway-related crash frequency and injury severity vary across observations. Using a methodology that does not account nor correct for heterogeneity in observed and unobserved crash factors across highway segments may lead to biased and inconsistent estimated coefficients, thus resulting in erroneous inferences. The present paper demonstrates the use of random-parameters models to facilitate and enhance how crash factors affect crash frequency and injury severity along a highway segment. The results indicate that a unit increase in the presence of stop sign along a highway segment reduces crash frequency by 2.471 for 87.24% of the roadway segments. For the remaining 12.76% of the roadway segments, crash frequency is increased by the same margin. Using the random-parameters multinomial logit model, the result indicates that, for 90.89% of the observations, the presence of a stop sign on a highway segment increases the probability of the injury outcome. For 9.11% of the observations, the presence of a stop sign on a highway segment reduces the probability of the injury outcome, and the marginal effect value across observations is 0.0017. Vertical grades greater than 5% increase crash frequency for 58.46% of the highway segments, and decrease for 41.54% of the highway segments by 0.121 for one unit increase in vertical grades.

    The lightning-induced-damages in the mid-latitude regions are usually caused during severe thunderstorms. But the discharge parameters of natural lightning are difficult to be measured. Five lightning flashes have been artificially triggered with the rocket-wire technique during the passage of two severe thunderstorms. The discharge current and close electric field of return stroke in artificially triggered lightning have been obtained in microsecond time resolution by using current measuring systems and electric field change sensors. The results show that the five triggered lightning flashes include 1 to 10 return strokes, and the average return stroke current is 11.9 kA with a maximum of 21.0 kA and a minimum of 6.6 kA, similar to the subsequent return strokes in natural lightning. The half peak width of the current waveform is 39 μs, which is much larger than the usual result. The peak current of stroke Ip (kA)and the neutralized charge Q(C) has a relationship of Ip = 18.5Q0.65. The radiation field of return stroke is increase of horizontal distance r from the discharge channel. Based on the well-accepted transmission results in this article can be used in the protection design of natural lightning.

    Background Urticarial dermatitis, which is characterised by persistent wheals with eczematous papules and plaques, is frequently misdiagnosed and difficult to treat. Patients commonly experience intolerable pruritus which may greatly affect their quality of life. Objective The objective of this study is to characterize the clinical patterns of pruritus in patients with urticarial dermatitis and to determine the effectiveness of cyclosporine treatment. Methods This prospective study included 50 histopathologically confirmed patients with urticarial dermatitis. A face-to-face structured questionnaire was given to all patients, and they were treated with low-dose cyclosporine (1~3 mg/kg/d) for at least 2 weeks. Results The majority of patients (80.0%) had moderate to severe pruritus. Most patients experienced exacerbation of the itch in the evening (74.0%), with the extremities (upper, 86.0%; lower, 94.0%) being the most commonly involved sites. Due to severe pruritus, patients complained about reduced social contact, quality of life and difficulties in falling asleep et al. Cyclosporine significantly reduced the mean itch score and extent of erythema, and improved interference with daily activities and sleep. Conclusion Our study highlights the detailed description and characteristics of pruritus in patients with urticarial dermatitis. And we recommend alternative and effective therapeutic option of low-dose cyclosporine.

    Objective To investigate the dynamic changes observed in serum levels of interleukins (ILs), tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) in severe acute respiratory syndrome (SARS) patients.Methods Sixty-one cases of SARS with positive antibodies to SARS coronavirus (SARS-CoV) were classified into the following categories: initial stage (3-7 days), peak stage (8-14 days), and remission and recovery stage (15-27 days). Forty-four healthy individuals were used as controls. Serum levels of ILs, TNF-α and TGF-β1 were measured in all subjects. Serum antibodies to SARS-CoV were detected only in SARS cases. Results The mean concentration of serum IL-6 in SARS patients did not differ from that in the control group in initial and peak stages, but became significantly higher in remission and recovery stage compared with the control group, initial and peak stages (P<0.01). The mean concentration of serum IL-8 in SARS patients did not differ from that of the control group in initial stage, but was significantly higher than control group in peak stage and remission and recovery stage (P<0.05). And it was more significantly higher in remission and recovery stage than in peak stage (P<0.01). The mean concentrations of IL-16 and TNF-α in SARS patients were higher than those of the control group for every length of the clinical courses investigated, and were especially high in remission and recovery stage (P<0.01). SARS patients experienced higher concentration of serum IL-13 compared with the controls in initial stage (P<0.01), but returned to normal levels in peak stage and in remission and recovery stage. The mean concentration of serum IL-18 in SARS patients was significantly lower than that of the control group during all clinical courses (P<0.05). The mean concentration of serum TGF-β1 in SARS patients was higher than that of the control group during all clinical courses. Although TGF-β1 in serum decreased in remission and recovery

    Three different types of Er doped photosensitive fibers, germanium/erbium (Ge/Er) fiber, tin/germanium/erbium fiber (Sn/Er) and antimony/germanium/erbium fiber (Sb/Er) have been manufactured and studied for use in optical sensor systems. Their characteristics of photosensitivity, the temperature sustainability of fiber Bragg gratings (FBGs) written into these fibers and the fluorescence emission from the Er dopant were investigated and compared. It has been shown in this work that these fibers all show a satisfactory degree of photosensitivity to enable the fabrication of FBGs and a significant level of fluorescence emission within the 1550 nm band for sensor use. The high temperature sustainability of the FBGs written into these fibers was investigated and seen to be quite significant at temperatures as high as 850 ^{\\circ}C, in particular for the Sn/Er and Sb/Er fibers. A fiber laser using the Sb/Er fiber as the gain medium was demonstrated, giving evidence of the strong fluorescence emission from the Er do...

    Cross-sectional data from 1,793 cases of definite or probable multiple sclerosis (MS) identified in an extensive population survey in King and Pierce (K-P) Counties, Washington and Los Angeles (LA) County, California, were analyzed. Compared to the U.S. population as a whole, patients were more likely to be divorced and to have more years of schooling. The prevalence of MS was higher for females, and for northern-born, regardless of sex. Reconstructed age-, sex-specific incidence rate estimates for natives of the two areas showed a much higher peak annual incidence occurring in an older age group in K-P than in LA. Earliest symptoms in both areas were numbness in the legs, double vision, and loss of vision in one or both eyes. Weakness in arms, speech difficulties, and urinary incontinence tended to be late symptoms. The overall assessment of disability levels showed more than half of the patients to be fully ambulatory at the time of the first interview, with a somewhat higher proportion of each sex severely disabled in California. The ages of onset tended to be younger in LA than in K-P. The earlier onset of disease and the higher proportion of patients with high disability in Los Angeles County suggest that the course of disease is more malignant in this low-prevalence area.

    2015-01-01

    Using essentially our 2011 numerical model of a multi-lymphangion segment of a collecting lymphatic vessel, but augmented by inclusion of a refractory period and definition of a mid lymphangion pressure, we explore the effect of several parameters on the form of pump function curves. Pump function is sensitively dependent on the shape of the passive constitutive relation between lymphangion diameter and transmural pressure. Maximum flow-rate increases with the diameter scale applied to the constitutive relation and decreases with the pressure scale. Both maximum flow-rate and maximum pressure difference which can be overcome increase as the excess of lymphangion chain inlet pressure over external pressure is reduced, until inlet pressure is low enough that lymphangion collapse intervenes. The results are discussed in comparison with findings from biological experiments.

    Sociodemographic differences between rural and urban clients with severe mental illness (SMI) are explored using approaches which extend research in this area beyond limitations found in the few existing studies. Sixteen hundred adult clients from 18 Wisconsin counties are classified according to the degree of rurality of their counties of residence, using two definitions: a dichotomous metropolitan-non-metropolitan grouping and population density. There are significant differences between rural and urban clients for age, gender, and marital status, but not education or income. Young (18-35 years), unmarried males are more likely to live in more densely populated counties. Older (65 and older) women who are currently or previously married are more likely to live in less densely populated counties.

The half peak width of the current waveform is 39 μs, which is much larger than the usual result. The peak current of stroke Ip (kA) and the neutralized charge Q(C) has a relationship of Ip = 18.5Q0.65. The radiation field of return stroke is 5.9 kV·m-1 and 0.39 kV·m-1 at 60 m and 550 m, respectively. The radiation field decreases as r -1.119 with increase of horizontal distance r from the discharge channel. Based on the well-accepted transmission line model, the speed of return stroke is estimated to be about 1.4×108 m·s-1, with a variation range of (1.1―1.6)×108 m·s-1. Because of the similarities of the triggered lightning and natural lightning, the results in this article can be used in the protection design of natural lightning.

    Full Text Available Pars planitis is an idiopathic chronic intermediate uveitis which predominantly affects children and adolescents, and accounts for 5-26.7% of pediatric uveitis. Although an autoimmune process with a genetic predisposition has been suggested, its etiology still remains unknown. The most common presenting symptoms are floaters and blurred vision. Diffuse vitreous cells, haze, snowballs and snowbanks are typical findings of pars planitis. Peripheral retinal vasculitis, optic disc edema and anterior segment inflammation are other well-known findings. Although pars planitis is known to be a benign form of uveitis in most cases, it may become a potentially blinding disease due to complications including cataract, cystoid macular edema, vitreous opacities and optic disc edema. Cystoid macular edema is the most common cause of visual morbidity. Band keratopathy, epiretinal membrane formation, vitreous condensation, neovascularizations, vitreous hemorrhage, retinal detachment, cyclitic membranes, glaucoma and amblyopia may develop as a consequence of the chronic course of the disease. Exclusion of infectious and non-infectious causes which may present with intermediate uveitis is of utmost importance before starting treatment. Treatment of pars planitis has been a controversial issue. There is no consensus specifically for treatment of cases with minimal inflammation and relatively good visual acuity. However, current experience shows that pars planitis may cause severe inflammation and needs an aggressive treatment. A stepladder approach including corticosteroids, immunosupressive agents, anti-tumor necrosis factor-alpha and pars plana vitrectomy and/or laser photocoagulation is the most commonly used method for treatment of pars planitis. Adequate control of inflammation and prompt detection of associated complications are crucial in order to improve the overall prognosis of the disease.

    The association between autism spectrum disorder (ASD) and epilepsy has been described for decades, and yet we still lack the full understanding of this relationship both clinically and at the pathophysiologic level. This review evaluates the available data in the literature pertaining to the clinical characteristics of patients with autism spectrum disorder who develop epilepsy and, conversely, patients with epilepsy who develop autism spectrum disorder. Many studies demonstrate an increased risk of epilepsy in individuals with ASD, but rates vary widely. This variability is likely secondary to the different study methods employed, including the study population and definitions of the disorders. Established risk factors for an increased risk of epilepsy in patients with ASD include intellectual disability and female gender. There is some evidence of an increased risk of epilepsy associated with other factors such as ASD etiology (syndromic), severity of autistic features, developmental regression, and family history. No one epilepsy syndrome or seizure type has been associated, although focal or localization-related seizures are often reported. The age at seizure onset can vary from infancy to adulthood with some evidence of a bimodal age distribution. The severity and intractability of epilepsy in populations with ASD have not been well studied, and there is very little investigation of the role that epilepsy plays in the autism behavioral phenotype. There is evidence of abnormal EEGs (especially epileptiform abnormalities) in children with ASD even in the absence of clinical seizures, but very little is known about this phenomenon and what it means. The development of autism spectrum disorder in patients with epilepsy is less well studied, but there is evidence that the ASD risk is greater in those with epilepsy than in the general population. One of the risk factors is intellectual disability, and there is some evidence that the presence of a particular seizure

    CFD analysis is presented of the mixing characteristics and performance of three fuel injectors at hypervelocity flow conditions. The calculations were carried out using the VULCAN-CFD solver and Reynolds-Averaged Simulations (RAS). The high Mach number flow conditions match those proposed for the planned experiments conducted as a part of the Enhanced Injection and Mixing Project (EIMP) at the NASA Langley Research Center. The EIMP aims to investigate scramjet fuel injection and mixing physics, improve the understanding of underlying physical processes, and develop enhancement strategies and functional relationships relevant to flight Mach numbers greater than eight. Because of the high Mach number flow considered, the injectors consist of a fuel placement device, a strut; and a fluidic vortical mixer, a ramp. These devices accomplish the necessary task of distributing and mixing fuel into the supersonic cross-flow albeit via different strategies. Both of these devices were previously studied at lower flight Mach numbers where they exhibited promising performance in terms of mixing efficiency and total pressure recovery. For comparison, a flush-wall injector is also included. This type of injector generally represents the simplest method of introducing fuel into a scramjet combustor, however, at high flight Mach number conditions, the dynamic pressure needed to induce sufficient fuel penetration may be difficult to achieve along with other requirements such as achieving desired levels of fuel-to-air mixing at the required equivalence ratio. The three injectors represent the baseline configurations planned for the experiments. The current work discusses the mixing flow field behavior and differences among the three fuel injectors, mixing performance as described by the mixing efficiency and the total pressure recovery, and performance considerations based on the thrust potential.

    BACKGROUND Several acute complications related to takotsubo cardiomyopathy (TTC) have been documented recently. However, the incidence and clinical significance of acute thromboembolic events in TTC is not well established. METHODS A detailed investigation of the clinical characteristics and in-hospital complications of 114 consecutive patients diagnosed with TTC between January 2003 and September 2015 was carried out. This study was initiated to reveal the predictors, clinical significance, and short-term and long-term outcomes of patients with TTC associated with acute thromboembolic events on index presentation. RESULTS The incidence of acute thromboembolic events related to TTC was around 12.2%, and these included ventricular thrombi, cerebrovascular events, retinal and brachial artery pathologies, renal, splenic, and aortic involvement. The most frequent complication on initial presentation was cardiogenic shock (20%) accompanied with pulmonary congestion (20%). Interestingly, patients experiencing thromboembolic events had higher C-reactive protein (CRP) levels as compared to the non-thromboembolic group (P = 0.02). Certain thromboembolic events were characterized by the presence of ST-segment elevation in electrocardiogram (P = 0.02). Chest pain was the primary symptom in these patients (P = 0.09). Furthermore, there was significant right ventricular involvement (as assessed by transthoracic echocardiography) in patients presenting with an acute thromboembolic event (P = 0.08). A Kaplan–Meier analysis indicated a significantly higher mortality rate over a mean follow-up of three years in the thromboembolic group than the non-thromboembolic group (log-rank, P = 0.02). CONCLUSIONS Our results confirmed the relative common occurrence of thromboembolic events in the setting of TTC. Inflammation might play an important role in the development of thromboembolic events, and a right ventricular involvement and ST-segment elevation could be positive predictors for

    Urinary tract infections (UTI) cause a great number of morbidity and mortality. These infections are serious complications in pregnancy, patients with diabetes, polycystic kidneys disease, sickle cell anaemia, kidney transplant and in patients with functional or structural anomalies of the urinary tract. The aim of this investigation was to determine a dominant causative agents of UTI and some of the clinical and laboratory characteristics of acute community-acquired UTI in adult hospitalised patients. We studied 200 adult patients with acute community-acquired UTI hospitalised in the Clinic for Infectious Diseases Tuzla from January 2006 to December 2007. The patients were divided into two groups: a group of patients with E. coli UTI (147) and a group of patients with non-E. coli UTI (53). In these two groups, the symptoms and signs of illness, blood test and urine analysis results were analysed. Our results have shown that the patients with E. coli UTI frequently had fever higher than 38,5 degrees C (p<0,0001), chills (p=0,0349), headache (p=0,0499), cloudy urine (p<0,0001), proteinuria (p=0,0011) and positive nitrite-test (p=0,0002). The patients with non-E. coli UTI frequently had fever lower than 38,5 degrees C (p<0,0001) and urine specific gravity <1015 (p=0,0012). There was no significant difference in blood test results between patients with E. coli and non-E. coli UTI. These clinical and laboratory findings can lead us to early etiological diagnosis of these UTI before urine culture detection of causative agents, which takes several days. Early etiological diagnosis of the E. coli and non-E. coli UTI is necessary for an urgent administration of appropriate empirical antibiotic treatment. This is very important in prevention of irreversible kidney damage, prolonged treatment, complications, as well as recidives and chronicity of the illness.

(Eds.), Epileptic Syndromes in Infancy, Childhood and Adolescence, third ed. John Libbey, London, pp. 81-103]. However, there is a group of severe epilepsy that has many characteristics common to SMEI except for myoclonic seizures. We reported this group of epilepsy as intractable childhood epilepsy with GTC (ICEGTC) [Watanabe, M., Fujiwara, T., Yagi, K., Seino, M., Higashi, T., 1989b. Intractable childhood epilepsy with generalized tonic-clonic seizures. J. Jpn. Epil. Soc. 7, 96-105 (in Japanese); Fujiwara, T., Watanabe, M., Takahashi, Y., Higashi, T., Yagi, K., Seino, M., 1992. Long-term course of childhood epilepsy with intractable grand mal seizures. Jpn. J. Psychiatr. Neurol. 46, 297-302]. Recently, mutations of the neuronal voltage-gated sodium channel alphasubunit type 1 gene (SCN1A) have been found in SMEI [Claes, L., Del-Favero, J., Ceulemans, B., Lagae, L., Van Broeckhoven, C., De Jonghe, P., 2001, De novo mutations in the sodium-channel gene SCN1A cause severe myoclonic epilepsy of infancy. Am. J. Hum. Genet. 68, 327-1332]. Mutations in SCN1A are found in both SMEI and ICEGTC at high rates of 70-81%. The loci of the mutations seen in ICEGTC are quite similar to those found in SMEI, suggesting a genotypic continuity between these entities. The clinical spectrum of epilepsies harboring SCN1A

    Full Text Available Abstract Background There was a pandemic influenza around the world in 2009 including South Korea since last pandemic occurred four decades ago. We aimed to evaluate the epidemiological and clinical characteristics of this infection in childhood. Methods We evaluated the epidemiologic characteristics of all the subjects infected with the 2009 H1N1 influenza A virus (2,971 patients, ≤ 15 years of age, and the clinical and laboratory findings of the inpatients (217 patients, 80 had pneumonia between 1 September 2009 and 31 January 2010 in a single hospital throughout the epidemic. Results The age distribution of all the subjects was relatively even. Over 90% of cases occurred during a two-month period. Two hundred and five patients (94.5% received oseltamivir within 48 h of fever onset, and 97% of inpatients defervesced within 48 h of medication. The group with pneumonia included more males than females, and had higher leukocytes counts with lower lymphocyte differentials than the group without pneumonia. The white blood cell count and lymphocyte differential were associated with the severity of pneumonia. Corticosteroid treatment for severe pneumonia patients was highly effective in preventing disease progression. Conclusion Children of all ages affected with even rates of infection, but males were predominant in pneumonia patients. Pneumonia patients showed lymphopenia and its severity was associated with the severity of illness. Our results suggest that the mechanism of lung injury in 2009 H1N1 virus infection may be associated with the host immune response.

    AIM: To evaluate the prevalence of upper gastrointestinal symptoms and their association with clinical and functional characteristics in elderly outpatients. METHODS: The study involved 3238 outpatients ≥ 60 years consecutively enrolled by 107 general practitioners. Information on social, behavioral and demographic characteristics, function in the activities of daily living (ADL), co-morbidities and drug use were collected by a structured interview. Upper gastrointestinal symptom data were collected by the 15-items upper gastro-intestinal symptom questionnaire for the elderly, a validated diagnostic tool which includes the following five symptom clusters: (1) abdominal pain syndrome; (2) reflux syndrome; (3) indigestion syndrome; (4) bleeding; and (5) non-specific symptoms. Presence and severity of gastrointestinal symptoms were analyzed through a logistic regression model. RESULTS: 3100 subjects were included in the final analysis. The overall prevalence of upper gastrointestinal symptoms was 43.0%, I.e. Cluster (1) 13.9%, (2) 21.9%, (3) 30.2%, (4) 1.2%, and (5) 4.5%. Upper gastrointestinal symptoms were more frequently reported by females (P < 0.0001), with high number of co-morbidities (P < 0.0001), who were taking higher number of drugs (P < 0.0001) and needed assistance in the ADL. Logistic regression analysis demonstrated that female sex (OR = 1.39, 95% CI: 1.17-1.64), disability in the ADL (OR = 1.47, 95% CI: 1.12-1.93), smoking habit (OR = 1.29, 95% CI: 1.00-1.65), and body mass index (OR = 1.06, 95% CI: 1.04-1.08), as well as the presence of upper (OR = 3.01, 95% CI: 2.52-3.60) and lower gastroenterological diseases (OR = 2.25, 95%CI: 1.70-2.97), psychiatric (OR = 1.60, 95% CI: 1.28-2.01) and respiratory diseases (OR = 1.25, 95% CI: 1.01-1.54) were significantly associated with the presence of upper gastrointestinal symptoms. CONCLUSION: Functional and clinical characteristics are associated with upper gastrointestinal symptoms. A multidimensional

    This study analyzed the climatological characteristics of severe convective storms in the Beijing and Tianjin region and its vicinity based on the Doppler radar data of Tanggu during May-August of 2003-2007. The climatological characteristics, e.g. storm area, volume, top height, max reflectivity, life time and motion, are analyzed. The results include: 75% of all storms in the Beijing-Tianjin region last no more than 30 minutes, and most storms have a volume less than 400 km3; most storms move from southwest to northeast while the speed is between 10-30 km/h; the mean storm top height is about 6 km, but some strong convective storms can have a top height larger than 15 km; finally, storm area and volume have a similar geographical distribution character showing increasing trends from west to east. Compared with the statistic results based on the conventional surface meteorological observations, the results based on the radar data can present not only 3D spatial statistic results of convective storms (e.g., volume and top height), but also the quantitative climatological characteristics, such as the lifetime and speed distributions. These statistical results are useful for studying the climatic characteristics of convective storms in the Beijing-Tianjin region and its vicinity.

    Ulcerative colitis(UC)is characterized by chronic inflammation of the large bowel in genetically suscep-tible individuals exposed to environmental risk factors.The disease course can be difficult to predict,with symptoms ranging from mild to severe.There is no generally accepted definition of severe UC,and no single outcome is sufficient to classify a disease course as severe.There are several outcomes indicating a severe disease course,including progression of the disease’s extension,a high relapse rate,the development of acute severe colitis,colectomy,the occurrence of colorectal cancer and UC-related mortality.When evaluating a patient’s prognosis,it is helpful to do so in relation to these outcomes.Using these outcomes also makes it easier to isolate factors predictive of severe disease.The aims of this article are to evaluate different disease outcomes and to present predictive factors for these outcomes.

    the pulmonology clinics of seven Asian cities and also evaluated whether the exposure to biomass fuels and dusty jobs were related to respiratory symptoms, airflow limitation, and quality of life in the COPD patients.Methods: This cross-sectional observational study recruited 922 COPD patients from seven cities of Asia. The patients underwent spirometry and were administered questionnaires about their exposure to cigarette smoking, biomass fuels, and dusty jobs in addition to respiratory symptoms and health related quality of life.Results: Of the patients, there appeared to be variations from city to city in the history of exposure to biomass fuels and dusty jobs and also in respiratory symptoms of cough, phlegm, wheeze, and dyspnea. These symptoms were more frequent in those COPD patients with a history of exposure to biomass fuels than without and those with a history of exposure to dusty jobs than without (P < 0.01 for all comparisons. Airflow limitation was more severe in those COPD patients with a history of exposure to biomass fuels than without (52.2% predicted versus 55.9% of post-bronchodilator forced expiratory volume in 1 second [FEV1], P = 0.009; quality of life was poorer in those with exposure to biomass fuels than without (40.4 versus 36.2 of the St George's Respiratory Questionnaire [SGRQ] total score, P = 0.001. Airflow limitation was more severe in those COPD patients with a history of exposure to dusty jobs than without (51.2% predicted versus 57.3% of post-bronchodilator FEV1, P < 0.001; quality of life was poorer in those with dusty jobs than without (41.0 versus 34.6 of SGRQ score, P = 0.006.Conclusion: In Asian cities, the characteristics of COPD patients vary and the history of exposure to biomass fuels or dusty jobs was related to frequency of symptoms, severe airflow limitation, and poor quality of life.Keywords: COPD, Asia, biomass, dust

    Staphylococcus aureus infection is a persistent threat in resource-restricted settings in southeast Asia but informative data about this disease remain limited. We analyzed characteristics, management, and predictors of outcome in severely septic patients with community-onset S. aureus infection in northeast Thailand. We performed a prospective, multicenter observational cohort study of community-onset S. aureus sepsis in four referral hospitals recruiting patients at least 14 years of age admitted between March 2010 and December 2013. One hundred and nineteen patients with severe staphylococcal sepsis were enrolled. Diabetes was the most common underlying condition. Methicillin-resistant infection was rare. Twenty-eight-day mortality was 20%. Ninety-two percent of patients received appropriate antibiotic therapy and 82% were administered intravenous fluids on the first hospital day, although only 14% were managed in an intensive care unit (ICU). On univariable analysis, clinical variables at enrollment significantly associated with death at 28 days were coagulopathy or respiratory failure. Plasma interleukin (IL) -8 concentration alone accurately predicted mortality (area under the receiver operating curve = 0.82, 95% confidence interval = 0.73-0.90). In multivariable analysis, addition of IL-8 concentration to a mortality prediction model containing clinical variables further improved the predictive ability of the model. We conclude that severe staphylococcal sepsis in northeast Thailand causes significant mortality. Diabetes is a common preexisting condition and most patients are managed outside the ICU even if they receive vasoactive/inotropic agents or mechanical ventilation. While clinical factors apparent on presentation including coagulopathy and respiratory failure predict death, plasma IL-8 improves this prediction.

    Full Text Available Rotavirus (RV infection in neonatal age can be mild or even asymptomatic. Several studies have reported that RV is responsible for 31%-87% of pediatric nosocomial diarrhea and causes gastroenteritis outbreaks in pediatric and neonatal units.Study clinical characteristics, genotypes and risk factors of RV infection in neonatal age.A prospective study was conducted from April 2009 till April 2013 in the neonatal special care unit of the largest tertiary pediatric hospital of Greece. Fecal samples and epidemiological data were collected from each neonate with gastrointestinal symptoms. RV antigen was detected with a rapid immunochromatography test. RV positive samples were further genotyped with RT PCR and sequencing using specific VP7 and VP4 primers.Positive for RV were 126/415 samples (30.4%. Mean age of onset was 18 days. Seventy four cases (58% were hospital acquired. Seasonality of RV infection did not differ significantly throughout the year with the exception of 4 outbreaks. Genotypes found during the study period were G4P[8] (58.7%, G1P[8] (14.7%, G12P[8] (9.3%, G3P[8] (9.3%, G12P[6] (5.3%, G9P[8] (1.3% and G2P[4] (1.3%. RV cases presented with: diarrhea (81%, vomiting (26.2%, fever (34.9%, dehydration (28.6%, feeding intolerance (39.7%, weight loss (54%, whilst 19% of cases were asymptomatic. Comparing community with hospital acquired cases differences in clinical manifestations were found.Significant incidence of nosocomially transmitted RV infection in neonatal age including asymptomatic illness exists. Genotypes causing nosocomial outbreaks are not different from community strains. Circulating vaccines can be effective in prevention of nosocomial RV infection through herd immunity.

    Full Text Available ABSTRACT Objectives: Innate immunity is involved in the physiopathology of ankylosing spondylitis (AS, with the participation of Gram-negative bacteria, modulation of human leukocyte antigen (HLA B27 and the involvement of pattern recognition receptors, such as Toll-like receptors (TLRs. The aim of this study was to investigate the clinical characteristics and frequency of TLR4 polymorphisms (Asp299Gly and Thr 399Ile in a cohort of Brazilian patients with AS. Methods: A cross-sectional study was carried out involving 200 patients with a diagnosis of AS and a healthy control group of 200 individuals. Disease activity, severity and functional capacity were measured. The study of TLR4 polymorphisms was performed using the restriction fragment length polymorphism method. HLA-B27 was analyzed by conventional polymerase chain reaction. The IBM SPSS Statistics 20 program was used for the statistical analysis, with p-values less than 0.05 considered significant. Results: Mean age and disease duration were 43.1 ± 12.7 and 16.6 ± 9.2 years, respectively. The sample was predominantly male (71% and non-Caucasian (52%. A total of 66% of the group of patients were positive for HLA-B27. The sample of patients was characterized by moderate functional impairment and a high degree of disease activity. No significant association was found between the two TLR4 polymorphisms and susceptibility to AS. Conclusions: TLR4 polymorphisms 399 and 299 were not more frequent in patients with AS in comparison to the health controls and none of the clinical variables were associated with these polymorphisms.

    Full Text Available Background: Acute Lower Respiratory Tract Infection (ALRTI is the leading cause of deaths in children under 5 years of age worldwide, and has high morbidity and mortality in children with Congenital Heart Disease (CHD. The objective of this study was to obtain the incidence, clinical characteristic, and outcome of ALRTI children with CHD. Methods: A retrospective hospital-based study was conducted from January 2007–December 2011 to medical record of child patients with ALRTI and CHD in the Department of Child Health of Dr. Hasan Sadikin General Hospital, Bandung. The diagnosis of CHD was determined by echocardiography. The collected data was analyzed and presented in percentage shown in tables. Results : From 3,897 children who had ALRTI, there were 149 children with CHD (3.8%, with 11.4% of whom founded with recurrent episodes. This happened often in girls than boys with quite similar ratio of 1.37: 1.The majority of children (80% was under 1 year old of age, 72.5% with malnutrition, and 24.8% with severe malnutrition. Clinical symptoms mostly found were difficulty of breathing (98%, fever (85.2%, cough (75.2%, and runny nose (63.1%. The most common types of CHD were Patent Ductus Arteriosus (47.6%, followed by Ventricular Septal Defect (47%. Bronchopneumonia (86.6% was the common type of ALRTI. The length of stay was mostly less than 10 days (70.5%. From all the children 43.7% had complications, and 6.7% died. Conclusions: The ALRTI in children with CHD is not common and has good outcome. The majority for CHD lesions are Patent Ductus Arteriosus and Ventricular Septal Defect while for ALRTI is Bronchopneumonia.

    Invasive infections due to carbapenem-resistant Enterobacteriaceae (CRE), including polymyxin-resistant (PR-CRE) strains, are being increasingly reported. However, there is a lack of clinical data for several life-threatening infections. Here we describe a cohort of patients with post-surgical mediastinitis due to CRE, including PR-CRE. This study was a retrospective cohort design at a single cardiology centre. Patients with mediastinitis due to CRE were identified and were investigated for clinically relevant variables. Infecting isolates were studied using molecular techniques. Patients infected with polymyxin-susceptible CRE (PS-CRE) strains were compared with those infected with PR-CRE strains. In total, 33 patients with CRE mediastinitis were studied, including 15 patients (45%) with PR-CRE. The majority (61%) were previously colonised. All infecting isolates carried blaKPC genes. Baseline characteristics of patients with PR-CRE mediastinitis were comparable with those with PS-CRE mediastinitis. Of the patients studied, 70% received at least one agent considered active in vitro and most patients received at least three concomitant antibiotics. Carbapenem plus polymyxin B was the most common antibiotic combination (73%). Over 90% of patients underwent surgical debridement. Overall, in-hospital mortality was 33% and tended to be higher in patients infected with PR-CRE (17% vs. 53%; P=0.06). In conclusion, mediastinitis due to CRE, including PR-CRE, can become a significant challenge in centres with CRE and a high cardiac surgery volume. Despite complex antibiotic treatments and aggressive surgical procedures, these patients have a high mortality, particularly those infected with PR-CRE.

    Patients with hypertensive crises, especially hypertensive emergencies, require immediate admittance to an intensive care unit for rapid blood pressure (BP) control. The authors analyzed the prevalence of hypertensive crisis, the clinical characteristics, and the evolution of patients with hypertensive emergencies and urgencies. Patients were divided into 3 groups according to their BP values: group I, predominant systolic hypertension (≥180/≤119 mm Hg); group II, severe systolic and diastolic hypertension (≥180/≥120 mm Hg); and group III, predominant diastolic hypertension (≤179/≥120 mm Hg). Of all of the patients admitted to a coronary care unit, 538 experienced a hypertensive crisis, which represented 5.08% of all admissions. Hypertensive emergency was predominant in 76.6% of the cases, which corresponded to acute coronary syndrome and acute decompensated heart failure in 59.5% and 25.2% of the cases, respectively. A pattern of predominant systolic hypertension (≥180/≤119 mm Hg) was most commonly observed in the hypertensive crisis group (71.4%) and the hypertensive emergency group (72.1%). The medications that were most commonly used at onset included intravenous vasodilators (nitroglycerin in 63.4% and sodium nitroprusside in 16.4% of the patients). The overall mortality rate was 3.7%. The mortality rate was 4.6% for hypertensive emergency cases and 0.8% for hypertensive urgencies cases.

Design: Retrospective, observational, cohort study. Setting: Intensive care unit (ICU of a university hospital. Materials and Methods: Microbiologically confirmed VAP due to CRA infection. Intervention: None. Results: Out of 87 patients with VAP due to CRA, 60 (69% were male; whose median age was 51 years; 73 (84% patients were medical; 26 (30% had history of hospitalization in last 3 months; median acute physiology and chronic health evaluation (APACHE II was 15 and median SOFA 9 at admission; primary reason for ICU admission was respiratory failure (34%; 46 (53% patients had more than 2 organ failure at ICU admission; median length of ICU stay was 19 days; 66 (76% patients need vasoactive agents during ICU stay, whereas 55 (63% patients had renal failure; median duration of mechanical ventilation was 17 days; 22 (25% patients had acute respiratory distress syndrome (ARDS during ICU stay; 72 (83% patients had exposure to carbapenem before inclusion in the study; 33 (38% patients had same organism at other sites. In the follow-up, 47 (54% patient survived at 28 days after having VAP; whereas only 40 (46% patients were discharged from the hospital. Conclusions: CRA-VAP has high crude mortality. Advanced age; severity of illness and presence of pneumonia at ICU admission; and presence of shock, ARDS and renal failure have impact on outcome in these patients.

    Full Text Available Despite the increased global prevalence and recognition of autistic spectrum disorder (ASD, it is still scarcely reported in the Arab world. Though Israel has a higher prevalence of ASD, a previous national survey of patients diagnosed between 1972 and 2004, demonstrated that 98% of them were of Jewish ancestry. The disproportional low number of Arab children with ASD in Israel is unclear but may reflect lower awareness and cultural bias. In the present study we collected clinical and demographic characteristics of 200 children with ASD from Arab and Jewish sectors in Israel that were evaluated in two child development centers. We compared the incidence and the medical comorbidity of autism between these two ethnics groups. The medical and psychiatric comorbidity profile in these children was similar to the worldwide published studies. In the present study the prevalence of autism in the Arab sector in Israel was similar to that of the Jewish sector. The Arab patients presented with more severe autistic manifestations and higher incidence of mental retardation, familial members with autism, and consanguinity (P<0.05, while in the Jewish sector milder forms (such as Asperger syndrome and PDD-NOS were more frequent. This discrepancy might be explained by both genetic and cultural factors.

    It is important to identify the severity of acute pancreatitis (AP) in the early course of the disease. Clinical scoring systems may be helpful to predict the prognosis of patients with early AP; however, few analysts have forecast the accuracy of scoring systems for the prognosis in hyperlipidemic acute pancreatitis (HLAP). The purpose of this study was to summarize the clinical characteristics of HLAP and compare the accuracy of conventional scoring systems in predicting the prognosis of HLAP. This study retrospectively analyzed all consecutively diagnosed AP patients between September 2008 and March 2014. We compared the clinical characteristics between HLAP and nonhyperlipidemic acute pancreatitis. The bedside index for severity of acute pancreatitis (BISAP), Ranson, computed tomography severity index (CTSI), and systemic inflammatory response syndrome (SIRS) scores were applied within 48 hours following admission. Of 909 AP patients, 129 (14.2%) had HLAP, 20 were classified as severe acute pancreatitis (SAP), 8 had pseudocysts, 9 had pancreatic necrosis, 30 had pleural effusions, 33 had SIRS, 14 had persistent organ failure, and there was 1 death. Among the HLAP patients, the area under curves for BISAP, Ranson, SIRS, and CTSI in predicting SAP were 0.905, 0.938, 0.812, and 0.834, 0.874, 0.726, 0.668, and 0.848 for local complications, and 0.904, 0.917, 0.758, and 0.849 for organ failure, respectively. HLAP patients were characterized by younger age at onset, higher recurrence rate, and being more prone to pancreatic necrosis, organ failure, and SAP. BISAP, Ranson, SIRS, and CTSI all have accuracy in predicting the prognosis of HLAP patients, but each has different strengths and weaknesses.

    Full Text Available Sickle cell anemia is an inflammatory disease and is characterized by chronic hemolysis. We sought to evaluate the association of lactate dehydrogenase levels with specific clinical phenotypes and laboratory variables in patients with sickle cell anemia.The present cross-sectional study was conducted in Sickle Cell Centre of Yolo in Kinshasa, the Democratic Republic of Congo. Two hundred and eleven patients with Sickle Cell Anemia in steady state were recruited. Seventy-four participants with normal Hb (Hb-AA were selected as a control group.The average rates of hemoglobin, hematocrit, and red blood cells tended to be significantly lower in subjects with Hb-SS (p<0.001. The average rates of white blood cells, platelets, reticulocytes and serum LDH were significantly higher in subjects with Hb-SS (p<0.001. The average rates of Hb, HbF, hematocrit and red blood cells of Hb-SS patients with asymptomatic clinical phenotype were significantly higher than those of the two other phenotypes. However, the average rates of white blood cells, platelets, reticulocytes, and LDH of Hb-SS patients with the severe clinical phenotype are higher than those of two other clinical phenotypes. Significant correlations were observed between Hb and white blood cell in severe clinical phenotype (r3 = -0.37 * between Hb and red blood cells in the three phenotypes (r1 = 0.69 * r2 * = 0.69, r3 = 0.83 *, and finally between Hb and reticulocytes in the asymptomatic clinical phenotype and severe clinical phenotype (r1 = -0.50 * r3 = 0.45 *. A significant increase in LDH was observed in patients with leg ulcer, cholelithiasis and aseptic necrosis of the femoral head.The increase in serum LDH is accompanied by changes in hematological parameters. In our midst, serum LDH may be considered as an indicator of the severity of the disease.

However, the average rates of white blood cells, platelets, reticulocytes, and LDH of Hb-SS patients with the severe clinical phenotype are higher than those of two other clinical phenotypes. Significant correlations were observed between Hb and white blood cell in severe clinical phenotype (r3 = -0.37 *) between Hb and red blood cells in the three phenotypes (r1 = 0.69 * r2 * = 0.69, r3 = 0.83 *), and finally between Hb and reticulocytes in the asymptomatic clinical phenotype and severe clinical phenotype (r1 = -0.50 * r3 = 0.45 *). A significant increase in LDH was observed in patients with leg ulcer, cholelithiasis and aseptic necrosis of the femoral head. Conclusion The increase in serum LDH is accompanied by changes in hematological parameters. In our midst, serum LDH may be considered as an indicator of the severity of the disease. PMID:25946088

    The goals of this study were first, to delineate the co-occurrence of parental severe physical aggression and verbal aggression toward clinic-referred adolescents, and second, to examine the interactive effects of parental severe physical aggression and verbal aggression on adolescent externalizing and internalizing behavior problems. This research involved 239 referrals of 11- to 18-year-old youth and their dual-parent families to a non-profit, private community mental health center in a semi-rural Midwest community. Multiple informants (i.e., adolescents and mothers) were used to assess parental aggression and adolescent behavior problems. More than half of clinic-referred adolescents (51%) experienced severe physical aggression and/or high verbal aggression from one or both parents. A pattern of interactive effects of mother-to-adolescent severe physical aggression and verbal aggression on adolescent behavior problems emerged, indicating that when severe physical aggression was present, mother-to-adolescent verbal aggression was positively associated with greater adolescent behavior problems whereas when severe physical aggression was not present, the links between verbal aggression and behavior problems was no longer significant. No interactive effects were found for father-to-adolescent severe physical aggression and verbal aggression on adolescent adjustment; however, higher father-to-adolescent verbal aggression was consistently linked to behavior problems above and beyond the influence of severe physical aggression. The results of this study should promote the practice of routinely assessing clinic-referred adolescents and their parents about their experiences of verbal aggression in addition to severe physical aggression and other forms of abuse.

    AIM: To retrospectively analyze the pathogenesis, clinical characteristics, treatment and prognostic characteristics in patients with traumatic basal ganglia hematomas (TBGH).METHODS: A retrospective analysis of the clinical data was performed in 40 patients with TBGH who were selected from 1 250 patients with closed brain injury, who admitted to the Department of Neurosurgery of Shangqiu First People's Hospital from January 1990 to January 2004. The pathogenesis, clinical characteristics and signs, results of radiological examination, treatment and prognostic characteristics were analyzed. The patients all had definite history of brain injury, manifested by neurological functional disturbance to different extent after brain injury, and basal ganglia hemorrhage was identified by CT after brain injury, and hemorrhagic volume were more than or equal to 2 mL. Totally 34 males and 6 females were enrolled, aged 16-72 years and 28 cases of them were younger than 40 years old. The prognosis of the patients was evaluated with Glasgow outcome scale (GOS) at 6 months after injury, and GOS scoring standard was 1-5 points (1 for dead; 2 for vegetative survival, long-term coma, manifestations of decorticate rigidity or decerebrate rigidity; 3 for severely disabled, should be look after by others; 4 for moderately disabled, be able in self-care; 5 for good recovery, adults can work and study).RESULTS: The enrolled cases accounted for 3.20% of the 1250 patients with closed brain injury admitted at the same period. ① The causes of injury included traffic accident in 36 cases, fall in 2 cases, and assault in 2 cases. ② At admission, the Glasgow coma scale (GCS) scores were as follow: 13-15 scores (mild) in 10 cases,9-12 scores (moderate)in 20 cases, and 3-8 scores (severe) in 10 cases. Hemiplegia presented in 37 cases,aphasia in 20 cases, conscious disturbance in 10 cases, unilateral mydriasis in 6 cases, and decerebrate rigidity in 2 cases. ③ TBGH was detected by CT within

    Full Text Available The aim of this study was to assess the role of HLA-B*27 and it's subtypes in determining severity and clinical manifestations of ankylosing spondylitis (AS.A total of 163 AS patients were assessed for clinical manifestations and severity using structured questionnaires. HLA-B*27 screening and B*27 sub-typing were performed by PCR.One hundred twenty two patients (74.8% were B*27 positive. The male to female ratio, peripheral arthritis, steroid use, intense dorsal kyphosis and decrease of cervical slope had a significantly higher frequency in B*27 positive patients compared to B*27 negative ones (p=0.01, 0.001, 0.01, 0.04 and 0.04, respectively. However, the age of diagnosis was significantly lower in B*27 positive patients (p=0.005. Trend in uveitis and some severity markers including: BASMI and ASQoL were toward higher values in B*27 positive group with no significant difference. After controlling confounding variables, significant relationship was found only between B*27 and BASMI (p=0.01. B*27 subtypes in patients were included B*2705: 48.4%, B*2702: 42.6%, B*2704: 5.7% and B*2707: 3.3%. No significant differences were seen for severity markers and clinical manifestations between subtypes; although trend toward lower values of severity markers, less intense dorsal kyphosis and less decrease of cervical slope were observed in B*2704 and B*2707 versus other polymorphisms.Clinical features and severity of AS is influenced by HLA-B*27. Trend toward higher severity markers in B*2705 and B*2702 versus other polymorphisms might be subject of interest for evaluation in other ethnicities with concentration to other novel susceptibility genes co-inherited in each B*27 subtype.
