    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.

    Full Text Available Aim: In our study, we aim to investigate the demographic, clinic features and the treatments of patients with moderate to severe psoriasis who were followed in outpatient clinic of psoriasis of Department of Dermatology in Istanbul Medical School of Istanbul University. Material and Method: One thousand eight hundred and thirty-one patients, who were followed between 2002-2008 in outpatient clinic of psoriasis, were screened and 626 (34% of them, who were moderate and severe, were evaluated retrospectively. Results: Three hundred five of the patients who participated in our study were female and 321 were male. Mean age of onset was 28.1. Most frequently clinical type was plaque psoriasis. Most frequently nail involvement was pitting in patients. Nail involvement was statistically common in arthropathic patients. Family history was statistically common in psoriasis patients with early onset. Retinoid was the most common used systemic drug. Narrow band UVB was the most common used phototherapy. Discussion: Moderate to severe psoriasis rate was 34%. Female to male ratio was close to one another. Peak age of onset of psoriasis was between 16-25 years old. The most common concomitant systemic disease was diabetes mellitus. The findings were consistent with the literature. Consequently psoriasis is a chronic, recurrent, inflammatory dermatologic disease which affect 2% of the word and which negatively affect the quality of life in patients with comorbidities. Especially in severe forms of psoriasis can cause loss of labor in patients. A good knowledge of demographic and clinical characteristics of psoriasis is important to shedding light on the further clinical studies.

    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.

    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.

    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.

    Objective To investigate the factors in relation with the case fatality in severe meconium aspiration syndrome (MAS). Methods Eighty-one severe MAS cases intervened by the mechanical ventilation from 9 children's hospitals were retrospectively analyzed for the risk factors of fatality with SAS software for non-parametric rank sum test and chi-square test. Results In the 81 cases, 49 were survived (death rate 39%). The gestational age (GA), Apgar's score at 1min and other complications with MAS were significantly related to the death (P 0.05). Conclusion A higher death rate (close to 40%) of severe MAS in the middle of 1990's in major cities of China suggests that it is important to detect the intrauterine hypoxemia as it may indicated by meconium staining amniotic fluid which should be intervened early by adequate termination of pregnancy before 42 weeks. The effects of delivery room suction and conventional ventilation also need to be reevaluated.

    U-BIOPRED is a European Union consortium of 20 academic institutions, 11 pharmaceutical companies and six patient organisations with the objective of improving the understanding of asthma disease mechanisms using a systems biology approach.This cross-sectional assessment of adults with severe asthma, mild/moderate asthma and healthy controls from 11 European countries consisted of analyses of patient-reported outcomes, lung function, blood and airway inflammatory measurements.Patients with severe asthma (nonsmokers, n=311; smokers/ex-smokers, n=110) had more symptoms and exacerbations compared to patients with mild/moderate disease (n=88) (2.5 exacerbations versus 0.4 in the preceding 12 months; plife, and higher levels of anxiety and depression. They also had a higher incidence of nasal polyps and gastro-oesophageal reflux with lower lung function. Sputum eosinophil count was higher in severe asthma compared to mild/moderate asthma (median count 2.99% versus 1.05%; p=0.004) despite treatment with higher doses of inhaled and/or oral corticosteroids.Consistent with other severe asthma cohorts, U-BIOPRED is characterised by poor symptom control, increased comorbidity and airway inflammation, despite high levels of treatment. It is well suited to identify asthma phenotypes using the array of "omic" datasets that are at the core of this systems medicine approach. PMID:26357963

    Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease that was caused by a novel bunyavirus, SFTSV. The study aimed to disclose the epidemiological and clinical characteristics of SFTSV infection in China so far. An integrated clinical database comprising 1920 SFTS patients was constructed by combining first-hand clinical information collected from SFTS sentinel hospitals (n = 1159) and extracted data (n = 761) from published literature. The considered variables comprised clinical manifestations, routine laboratory tests of acute infection, hospitalization duration and disease outcome. SFTSV-IgG data from 19 119 healthy subjects were extracted from the published papers. The key clinical variables, case-fatality rate (CFR) and seroprevalence were estimated by meta-analysis. The most commonly seen clinical manifestations of SFTSV infection were fever, anorexia, myalgia, chill and lymphadenopathy. The major laboratory findings were elevated lactate dehydrogenase, aminotransferase, followed by thrombocytopenia, lymphocytopenia, elevated alanine transaminase and creatine kinase. A CFR of 12·2% was estimated, significantly higher than that obtained from national reporting data, but showing no geographical difference. In our paper, the mortality rate was about 1·9 parts per million. Older age and longer delay to hospitalization were significantly associated with fatal outcome. A pooled seroprevalence of 3·0% was obtained, which increased with age, while comparable for gender. This study represents a clinical characterization on the largest group of SFTS patients up to now. A higher than expected CFR was obtained. A wider spectrum of clinical index was suggested to be used to identify SFTSV infection, while the useful predictor for fatal outcome was found to be restricted. PMID:26542444

    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.

    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.

    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.

Objective: To describe the epidemiological and clinical characteristics of severe community-acquired pneumonia in children after the introduction of the 10-valent pneumococcal conjugate vaccine (PCV10. Methods: A prospective study included children <5 years old hospitalized for pneumonia between October 2010 and September 2013 in a tertiary hospital. Newborns and children with comorbidities were excluded. Pneumonia classification followed the clinical and radiological criteria established by World Health Organization (WHO. Clinical history, nutritional status, immunizations, diagnosis, disease course, and prognosis were analyzed. Results: Among 452 children, almost 70% were <2 years, with no sex differences, and 10% had weight-for-age z score below than -2.0. Family income was up to one minimum wage in half the households, and 40% of mothers had completed high school. The suitability of both influenza and PCV10 vaccine schedules was ~50%. The first medical care happened later than 72 hours after the onset of symptoms in 42% of cases. Pneumonia was classified as severe or very severe in 83.9% of patients and for 23% as complicated. Global mortality was 1.5%. Hypoxia, diagnosed in 51.5% of children, looked like a better prognosis predictor than the WHO classification. Conclusion: New strategies for health care are necessary, such as the incorporation of peripheral saturometry as the

    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.

    Background Despite a high burden of respiratory syncytial virus (RSV) infections among children, data on demographic and clinical characteristics of RSV are scarce in low and middle income countries. This study aims to describe the viral etiologies, the demographic, epidemiological, and clinical characteristics of children under two years of age who were hospitalized with a lower respiratory tract infections (LRTI), focusing on RSV (prevalence, seasonality, subgroups, viral load) and its association with disease severity. Methods A prospective study among children under two years of age, hospitalized with LRTI was conducted in two referral pediatric hospitals in Ho Chi Minh City, Vietnam, from May 2009 to December 2010. Socio-demographic, clinical data and nasopharyngeal swabs were collected on enrolment and discharge. Multiplex real-time RT-PCR (13 viruses) and quantitative RSV RT-PCR were used to identify viral pathogens, RSV load and subgroups. Results Among 632 cases, 48% were RSV positive. RSV infections occurred at younger age than three other leading viral infections i.e rhinovirus (RV), metapneumovirus (MPV), parainfluenza virus (PIV-3) and were significantly more frequent in the first 6 months of life. Clinical severity score of RSV infection was significantly higher than PIV-3 but not for RV or MPV. In multivariate analysis, RV infection was significantly associated with severity while RSV infection was not. Among RSV infections, neither viral load nor viral co-infections were significantly associated with severity. Young age and having fever at admission were significantly associated with both RSV and LRTI severity. A shift in RSV subgroup predominance was observed during two consecutive rainy seasons but was not associated with severity. Conclusion We report etiologies, the epidemiological and clinical characteristics of LRTI among hospitalized children under two years of age and risk factors of RSV and LRTI severity. PMID:27500954

    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.

    Full Text Available Pain is the most feared symptom in cancer. About 52-77% patients suffer pain despite World Health Organization (WHO recommendations. Out of total, one-third patients suffer moderate to severe pain. This study was undertaken to determine the prevalence, etiopathogenesis and characteristics of severe pain and treatment response among pain clinic referrals in a busy tertiary care cancer center. This study found a high prevalence (31.5% of severe pain. A total of 251 patients who had complete pain data were analyzed for etiopathological characteristics and treatment response. Head and neck cancer contributed the highest prevalence among all regions. Oncologists prescribed non-steroidal anti-inflammatory drugs (NSAIDs or paracetamol with or without mild opioids to 14% patients and pain clinic physicians prescribed opioids and overall 63.7% patients had a better response after pain clinic referral, even then, morphine was not prescribed to many deserving patients. Doctors need pain education about opioids to remove any fear of prescribing opioids in presence of severe pain.

    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.

    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.

    Emergency department (ED) pain assessment documentation in trauma patients is critical to ED pain care. This retrospective, cross-sectional study used trauma registry data to evaluate U.S. military combat zone trauma patients injured between 2010 and 2013 requiring ≥ 24-hr inpatient care. Study aims were to identify the frequency of combat zone ED pain assessment documentation and describe pain severity. Secondary aims were to construct statistical models to explain variation in pain assessment documentation and pain severity.Pain scores were documented in 60.5% (n = 3,339) of the 5,518 records evaluated. The proportion of records with ED pain scores increased yearly. Pain assessment documentation was associated with documentation of ED vital signs, comprehensive facility, more recent year, prehospital (PH) heart rate of 60-100 beats/min, ED Glasgow Coma Scale score of 15 vs. 14, blunt trauma, and lower injury severity score (ISS).Pain severity scores ranged from 0 to 10; mean = 5.5 (SD = 3.1); median = 6. Higher ED pain scores were associated with Army service compared with Marine Corps, no documented PH vital signs, higher PH pain score, ED respiratory rate 16, moderate or severe ISS compared with minor ISS, treatment in a less-equipped facility, and injury in 2011 or 2012 vs. 2010. The pain severity model explained 20.4% of variance in pain severity.Overall, frequency of pain assessment documentation in combat-zone EDs improved yearly, but remained suboptimal. Pain severity was poorly predicted by demographic, clinical, and health system variables available from the trauma registry, emphasizing the importance of individual assessment. PMID:27618374

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 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.

  14. Intracranial Infections: Clinical and Imaging Characteristics

    International Nuclear Information System (INIS)

    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

    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.

  16. 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%.

    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.

    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.

    Full Text Available Background : Acute gastroenteritis is a common cause of dehydration and precise estimation of dehydration is a vital matter for clinical decisions. We try to find how much clinically diagnosed scales are compatible with laboratory tests measures. Materials and Methods : During 2 years 95 infants and children aged between 2 and 108 months entered to emergency room with acute gastroenteritis. They were categorized as mild, moderate and severe dehydration, their recorded laboratory tests include blood urea nitrogen (BUN, creatinine, venous blood gases values were expressed by means ±95% of confidence interval and compared by mann-whitney test in each groups with SPSS 16, sensitivity, specificity and likelihood ratio measured for defined cut off values in severe dehydration group, P value less than 0.05 was significant. Result : Severe dehydration includes 3% of all hospitalization due to dehydration. Laboratory tests cannot differentiate mild to moderate dehydration definietly but this difference is significant between severe to mild and severe to moderate dehydration. Conclusion : R outine laboratory test are not generally helpful for dehydration severity estimation but they can be discriminate severe from mild or moderate dehydration exclusively. Creatinine higher than 0.9 mg/dl and Base deficit beyond-16 are specific (90% for severe dehydration estimation in infant and children.

    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.

    @@ 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.

    Full Text Available Background/Aims: Ambulatory blood pressure monitoring (ABPM in chronic kidney disease (CKD patients has been extensively studied, but few investigations have attempted to relate ABPM with CKD stages. The objectives of this article were to compare ABPM parameters for the diagnosis and treatment determination of CKD with daytime clinic blood pressure (BP measurements. We also investigated BP and renal injury in combined hypertension and CKD. We supposed ABPM was important in combined hypertension and CKD. Methods: We compared ABPM in hypertension patients, including 152 patients with combined hypertension and CKD. Patients with combined hypertension and CKD were grouped according to severity into stages 1 through 3 (Stage 1-3 and stages 4 and 5 (Stage 4-5. Results: In the Stage 4-5 group, systolic BP (SBP (daytime, nighttime and 24 h mean, diastolic BP (DBP, pulse pressure and SBP standard deviations (SD (daytime and 24 h were higher. SBP and DBP loads were significantly higher in the Stage 4-5 group. The nighttime load was higher than the daytime load. Mean arterial pressure (MAP was higher and heart rates (HR were faster in the Stage 4-5 group. Conclusions: BP load should be a component employed in ABPM to determine cardiovascular risk stratification. MAP and HR might be associated with risk to develop end-stage renal disease.

    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.

    2016-01-01

    Background Pregabalin is approved by the US Food and Drug Administration for the treatment of fibromyalgia (FM), diabetic peripheral neuropathy (DPN), postherpetic neuralgia (PHN), and neuropathic pain due to spinal cord injury (SCI). Approval was based on clinical trial data demonstrating statistically significant differences in pain scores versus placebo. However, statistically significant pain relief may not always equate to clinically meaningful pain relief. To further characterize the clinical benefit of pregabalin, this analysis examined shifts in pain severity categories in patients with FM, DPN/PHN (pooled in this analysis), and SCI treated with pregabalin. Methods Data were pooled from 23 placebo-controlled trials in patients with FM (1,623 treated with pregabalin, 937 placebo), DPN/PHN (2,867 pregabalin, 1,532 placebo), or SCI (181 pregabalin, 175 placebo). Pain scores were assessed on an 11-point numeric rating scale and categorized as mild (0 to <4), moderate (4 to <7), or severe (7 to 10). Only patients with mean score ≥4 at baseline were randomized to treatment. The percentage of patients shifting pain category from baseline to endpoint for pregabalin and placebo was analyzed using a modified ridit transformation with the Cochran–Mantel–Haenszel procedure. Results A higher proportion of patients shifted to a less severe pain category at endpoint with pregabalin compared with placebo. With flexible-dose pregabalin, the percentage of patients improving from: severe to mild (pregabalin versus placebo) was 15.8 versus 13.4 in FM patients, 36.0 versus 16.6 in DPN/PHN patients, 14.3 versus 7.7 in SCI patients; severe to moderate was 28.7 versus 28.2 in FM patients, 32.5 versus 28.2 in DPN/PHN patients, 35.7 versus 28.2 in SCI patients; and moderate to mild was 38.3 versus 26.4 in FM patients, 59.5 versus 41.4 in DPN/PHN patients, 38.6 versus 27.2 in SCI patients. Conclusion Compared with placebo, pregabalin is more often associated with clinically

    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)

    Cerebellar glioblastomas (GBMs) are rare, with neither their pathogenesis nor prognosis being completely understood. The present study aimed to clarify the clinical characteristics of cerebellar GBMs by comparison with supratentorial GBMs, focusing particularly on the pathogenesis. The clinical factors between cerebellar (n=10) and supratentorial (n=216) GBMs were compared. Additionally, p53 and epidermal growth factor receptor (EGFR) levels were investigated in six patients by immunostaining as well as the isocitrate dehydrogenase 1 (IDH1) status of five patients by direct sequencing. Eight males and two females participated in the present study, the mean age at diagnosis was 56.6 years and the range 37-75 years. Four patients presented with hydrocephalus and one with brainstem involvement, and two patients were diagnosed with neurofibromatosis type 1. Two patients had previously received radiotherapy, eight patients received postoperative radiotherapy and seven chemotherapy. The mean Karnofsky performance status (KPS) score was lower in patients with cerebellar GBMs compared to those with supratentorial GBM; however, the survival times did not differ between the two groups. All of the cases of six cerebellar GBMs were p53‑positive and EGFR‑negative, as detected by immunostaining, consistent with secondary GBM. However, no IDH1 mutations were detected in any of the five cases of cerebellar GBMs analyzed, indicating that these tumors were not of the secondary type. The KPS score with cerebellar GBMs may be lower due to hydrocephalus, which was ameliorated by surgery but may have impacted the survival rate. It was confirmed that cerebellar GBMs were identical to supratentorial GBMs with respect to its clinical features, with the possible exception of the KPS score. The present study's genetic analyses indicated that cerebellar GBMs may develop via a pathway different from that of either primary or secondary GBM. PMID:25199771

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.

    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)

    Implants from Poly Implant Prothése (PIP), the French manufacturer, showed increased risk of implant rupture and silicone leakage through the shell. Concerns also exist about the potential irritant behavior of silicone gel filler in these implants. This report presents the clinical, histologic, and microbiologic characteristics of a capsule and a siliconoma from a patient with a ruptured PIP implant. A 41-year-old woman submitted to breast augmentation in 2005 with PIP silicone gel implants presented with a recent history of progressive asymmetric breast enlargement and an enlarged lymph node on her right axilla. No capsular contracture was observed. A breast ultrasonography showed intra- and extracapsular ruptures of the right implant. The woman underwent explantation. Histologic analysis of the breast capsules showed a thin capsule with a chronic, mild inflammatory response. Microbiologic analysis showed no bacterial agent. The irritant behavior of the PIP silicone gel previously described was not able to produce capsular contracture or an exuberant inflammatory reaction. Studies to evaluate the potential risks of the silicone gel and to define the hazards for women implanted with those prostheses are urgently needed. PMID:23943050

    Mutations in BRAT1, encoding BRCA1-associated ATM activator 1, are associated with a severe phenotype known as rigidity and multifocal seizure syndrome, lethal neonatal (RMFSL; OMIM # 614498), characterized by intractable seizures, hypertonia, autonomic instability, and early death. We expand the phenotypic spectrum of BRAT1 related disorders by reporting on four individuals with various BRAT1 mutations resulting in clinical severity that is either mild or moderate compared to the severe phenotype seen in RMFSL. Representing mild severity are three individuals (Patients 1-3), who are girls (including two sisters, Patients 1-2) between 4 and 10 years old, with subtle dysmorphisms, intellectual disability, ataxia or dyspraxia, and cerebellar atrophy on brain MRI; additionally, Patient 3 has well-controlled epilepsy and microcephaly. Representing moderate severity is a 15-month-old boy (Patient 4) with severe global developmental delay, refractory epilepsy, microcephaly, spasticity, hyperkinetic movements, dysautonomia, and chronic lung disease. In contrast to RMFSL, his seizure onset occurred later at 4 months of age, and he is still alive. All four of the individuals have compound heterozygous BRAT1 mutations discovered via whole exome sequencing: c.638dupA (p.Val214Glyfs*189); c.803+1G>C (splice site mutation) in Patients 1-2; c.638dupA (p.Val214Glyfs*189); c.419T>C (p.Leu140Pro) in Patient 3; and c.171delG (p.Glu57Aspfs*7); c.419T>C (p.Leu140Pro) in Patient 4. Only the c.638dupA (p.Val214Glyfs*189) mutation has been previously reported in association with RMFSL. These patients illustrate that, compared with RMFSL, BRAT1 mutations can result in both moderately severe presentations evident by later-onset epilepsy and survival past infancy, as well as milder presentations that include intellectual disability, ataxia/dyspraxia, and cerebellar atrophy. © 2016 Wiley Periodicals, Inc.

    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.

    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 OBJECTIVES: The aim of this study was to explore cognitive flexibility in a large dataset of people with Eating Disorders and Healthy Controls (HC and to see how patient characteristics (body mass index [BMI] and length of illness are related to this thinking style. METHODS: A dataset was constructed from our previous studies using a conceptual shift test--the Brixton Spatial Anticipation Test. 601 participants were included, 215 patients with Anorexia Nervosa (AN (96 inpatients; 119 outpatients, 69 patients with Bulimia Nervosa (BN, 29 Eating Disorder Not Otherwise Specified (EDNOS, 72 in long-term recovery from AN (Rec AN and a comparison group of 216 HC. RESULTS: The AN and EDNOS groups had significantly more errors than the other groups on the Brixton Test. In comparison to the HC group, the effect size decrement was large for AN patients receiving inpatient treatment and moderate for AN outpatients. CONCLUSIONS: These findings confirm that patients with AN have poor cognitive flexibility. Severity of illness measured by length of illness does not fully explain the lack of flexibility and supports the trait nature of inflexibility in people with AN.

    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.

    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.

    2004-05-01

    Severe acute respiratory syndrome (SARS) is a recently emerged infectious disease with significant morbidity and mortality. An epidemic in 2003 affected 8,098 patients in 29 countries with 774 deaths. The aetiological agent is a new coronavirus spread by droplet transmission. Clinical and general laboratory manifestations included fever, chills, rigor, myalgia, malaise, diarrhoea, cough, dyspnoea, pneumonia, lymphopenia, neutrophilia, thrombocytopenia, and elevated serum lactate dehydrogenase (LD), alanine aminotransferase (ALT) and creatine kinase (CK) activities. Treatment has been empirical; initial potent antibiotic cover, followed by simultaneous ribavirin and corticosteroids, with or without pulse high-dose methylprednisolone, have been used. The postulated disease progression comprises (1) active viral infection, (2) hyperactive immune response, and (3) recovery or pulmonary destruction and death. We investigated serum LD isoenzymes and blood lymphocyte subsets of SARS patients, and found LD1 activity as the best biochemical prognostic indicator for death, while CD3+, CD4+, CD8+ and natural killer cell counts were promising predictors for intensive care unit (ICU) admission. Plasma cytokine and chemokine profiles showed markedly elevated Th1 cytokine interferon (IFN)-gamma, inflammatory cytokines interleukin (IL)-1beta, IL-6 and IL-12, neutrophil chemokine IL-8, monocyte chemoattractant protein-1 (MCP-1), and Th1 chemokine IFN-gamma-inducible protein-10 (IP-10) for at least two weeks after disease onset, but there was no significant elevation of inflammatory cytokine tumor necrosis factor (TNF)-alpha and anti-inflammatory cytokine IL-10. Corticosteroid reduced IL-8, MCP-1 and IP-10 concentrations from 5-8 days after treatment. Measurement of biochemical markers of bone metabolism demonstrated significant but transient increase in bone resorption from Day 28-44 after onset of fever, when pulse steroid was most frequently given.

    Background The controversy on the treatment strategy for severe acute pancreatitis (SAP) has never stopped for the past century.Even now surgical procedures play a decisive role in the treatment of SAP,especially in managing the related complications,but the rational indications,timing,and approaches of surgical intervention for SAP are still inconclusive.Methods Clinical data of 308 SAP patients recruited during January 2000-January 2013,including 96 conservatively treated cases plus 212 surgically intervened cases,were comparatively analyzed.Based on the initial surgical intervention time,the surgical intervention group was split into two:early intervention group (within 2 weeks) 103 cases,and late intervention group (after 2 weeks) 109 cases.Results In the conservative treatment group,the cure rate was 82.29% (79/96),the death rate was 13.54% (13/96),and 4 cases self-discharged,while in the surgical intervention group,the cure rate was 84.43% (179/212) and the death rate was 10.85% (23/212) with 10 cases self-discharged.The difference was of no statistical significance between these two groups (P >0.05).In surgical intervention group,the death rate 15.53% (16/103) in the early surgical intervention group was higher than that of late surgical intervention group 6.42% (7/109),and the difference was statistically significant (P <0.05).Conclusions Both conservative treatment and surgical intervention play important roles in the treatment of SAP,and the indication,timing,and procedure should be strictly followed.Surgery earlier than 2 weeks after onset of the disease is not recommended in patients with necrotizing pancreatitis only when there are specific indications,such as multiple organ failure,which does not improve despite active treatment,and in those who develop abdominal compartment syndrome.

    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

    Fifty adults with either a present or past complaint of somnambulism were evaluated to determine the development and clinical course of their disorder as well as their personality patterns. Generally, when sleepwalking was outgrown, its onset was before age 10 years and its termination before age 15 years. Current sleepwalkers, compared with past sleepwalkers, started sleepwalking at a later age, had a higher frequency of events, and had episodes earlier in the night. Their episodes were also characterized by more intense clinical manifestations. Furthermore, current sleepwalkers demonstrated high levels of psychopathology, whereas past sleepwalkers had essentially normal psychological patterns. Specifically, the current sleepwalkers showed active, outwardly directed behavioral patterns, suggestive of difficulties in handling aggression. The clinical application of these findings is discussed and practical recommendations are given for the evaluation and management of sleepwalking. PMID:7447621

    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.

    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.

    1993-06-01

    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.

    Full Text Available Background: ADEM, although relatively uncommon, is probably under-recognized. Objectives: To spotlight the clinical profile and therapeutic outcome of children with ADEM. Materials and Methods: This is a prospective study of patients with ADEM who were admitted to the Pediatric Departments in Aladan and Alfarawanya Hospitals in Kuwait, from January 2009 to January 2011. Clinical, microbiological and radiological data were analyzed. Results: Of 48 patients presented with acute neurological symptoms and signs, 21 patients fulfilled criteria for ADEM. 80.95% of cases were presenting in winter and spring, 57% of patients had a history of upper respiratory tract illness. The commonest presentations were motor deficits, convulsions and altered consciousness. CSF virology studies showed herpes simplex virus (HSV and Epstein-Barr virus (EBV (3 patients whereas nasal and nasopharyngeal swab showed evidence of influenza H1N1 virus (1 patient. 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.

  5. Clinical relevance and discriminatory value of elevated liver aminotransferase levels for dengue severity.

    Directory of Open Access Journals (Sweden)

    Linda K Lee

    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.

    The development and clinical course of night terrors and the personality patterns of patients with this disorder were evaluated in 40 adults who had a current complaint of night terrors. Compared with a group of adult sleepwalkers, the patients with night terrors had a later age of onset for their disorder, a higher frequency of events, and an earlier time of night for the occurrence of episodes. Both groups had high levels of psychopathology, with higher values for the night terror group. This sleepwalkers showed active, outwardly directed behavioral patterns, whereas the night terror patients showed an inhibition of outward expressions of aggression and a predominance of anxiety, depression, tendencies obsessive-compulsive/, and phobicness. Although night terrors and sleepwalking in childhood seem to be related primarily to genetic and developmental factors, their persistence and especially their onset in adulthood are found to be related more to psychological factors.

    2012-01-01

    Posttraumatic stress disorder is a syndrome with a very complex clinical that it is useful to describe according to a multidimensional approach. Following a critical review of the international literature, we have been able to highlight the genetic supports of posttraumatic stress disorder in the perspective of returning to the source of the clinical of this syndrome in order to steer its treatment better. We consider in succession the neuromodulation pathways involving dopamine, serotonine and noradrenaline to describe the hyperdomaminergic, hyposerotoninergic and hypernoradrenergic endophenotypes of posttraumatic stress disorder. Neurogenetic studies have affirmed two essential proposals. On the one hand, the pharmacological treatment of psychotraumatic disorders can be very closely adjusted to the different endophenotypes. On the other hand, the psychotherapeutic approach retains all its importance in the sense that it is the subjective implication that generated the trauma, subjectivity interacting with a genetic heritage and environmental factors integrating a social context. The changing definition of posttraumatic stress disorder over time comes from scientific exploration in part determined by a sociocultural context and, reciprocally, the psychic trauma is caused by the collapse of reassuring social values which were considered as immutable. The clinical is not developed according to fixed references: the evolution of neurogenetic techniques changes our perception of psychic traumas and the therapeutic possibilities. PMID:23167137

    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

    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.

    A single monoclonal protein typically characterizes monoclonal gammopathies, but a small proportion may have more than one M protein identifiable. In the setting of symptomatic multiple myeloma (MM), the development of a new monoclonal protein following therapy is associated with better outcomes. As for the precursor conditions, monoclonal gammopathy undetermined significance (MGUS) and smoldering multiple myeloma (SMM), there is limited information on the impact of a second monoclonal protein on the disease course, including progression and response to treatment. The outcomes of patients with MGUS and SMM with more than one monoclonal protein, after identifying 539 patients with biclonal proteins on electrophoresis and/or immunofixation, were reported. About 22 of 393 patients with MGUS/biclonal gammopathy of undetermined significance (BGUS) progressed to SMM (6), MM (11), AL (3), or WM (2), and 5 of 16 patients with biclonal SMM progressed to MM. The rate of progression for BGUS was approximately 1% per year, which is similar to MGUS with one monoclonal protein. The median estimated time of progression of biclonal SMM was 2.6 years; similar to monoclonal SMM. For patients with biclonal MM, both M spikes responded to treatment and, upon relapse, the original dominant M protein remained dominant as the disease progressed. In conclusion, the presence of a second monoclonal protein does not appear to affect the progression of precursor states and suggests multiple monoclonal proteins do not clinically impact one another in the course of the disease.

    Objective To investigate the clinical and imaging characteristics of severe acute respiratory syndrome (SARS), and to study their relationship. Methods Forty-six SARS confirmed patients were admitted to our hospital from February to April, 2003. X-ray examination documents were available in all cases and chest CT scanning was acquired in 6 cases, which were analyzed retrospectively, accompanied by their clinical features. Results Fever was found in 97.8% of the patients. Clinical symptoms were mild, but X-ray and CT findings were distinct. CT scanning demonstrated ground glass like lesions and large patchy exudation and consolidation at the early stage in 6 cases. Different findings on radiography and CT were related to the different phases of the disease. After treatment, most lesions were absorbed completely, but slowly in patients with multi-lobe consolidation and/or extensive interstitial infiltration. Conclusion Special clinical and imaging findings could be found in SARS cases. The prognosis of SARS patients is related to the degree of lesions detected by radiography and CT.

    Objective To examine the relationship between cycling injury severity and personal, trip, route and crash characteristics. Methods Data from a previous study of injury risk, conducted in Toronto and Vancouver, Canada, were used to classify injury severity using four metrics: (1) did not continue trip by bike; (2) transported to hospital by ambulance; (3) admitted to hospital; and (4) Canadian Triage and Acuity Scale (CTAS). Multiple logistic regression was used to examine associations with personal, trip, route and crash characteristics. Results Of 683 adults injured while cycling, 528 did not continue their trip by bike, 251 were transported by ambulance and 60 were admitted to hospital for further treatment. Treatment urgencies included 75 as CTAS=1 or 2 (most medically urgent), 284 as CTAS=3, and 320 as CTAS=4 or 5 (least medically urgent). Older age and collision with a motor vehicle were consistently associated with increased severity in all four metrics and statistically significant in three each (both variables with ambulance transport and CTAS; age with hospital admission; and motor vehicle collision with did not continue by bike). Other factors were consistently associated with more severe injuries, but statistically significant in one metric each: downhill grades; higher motor vehicle speeds; sidewalks (these significant for ambulance transport); multiuse paths and local streets (both significant for hospital admission). Conclusions In two of Canada's largest cities, about one-third of the bicycle crashes were collisions with motor vehicles and the resulting injuries were more severe than in other crash circumstances, underscoring the importance of separating cyclists from motor vehicle traffic. Our results also suggest that bicycling injury severity and injury risk would be reduced on facilities that minimise slopes, have lower vehicle speeds, and that are designed for bicycling rather than shared with pedestrians.

    Full Text Available Abstract Background During clinical placements, clinical educators facilitate student learning. 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

    ·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.

    Objective: To determine the clinical and biochemical characteristics of children with Juvenile Idiopathic Arthritis (JIA) at a tertiary care centre in Karachi, Pakistan. Study Design: A descriptive study. Place and Duration of Study: Paediatric Rheumatology Clinic of The Aga Khan University Hospital (AKUH), Karachi, from January 2008 to December 2011. Methodology: Clinical and laboratory profile and outcome of children less than 15 years of age attending the Paediatric Rheumatology Clinic of the Aga Khan University, Karachi with the diagnosis of Juvenile Idiopathic Arthritis according to International League against Rheumatism were studied. These children were classified into different types of JIA; their clinical and laboratory characteristics, response to therapy and outcome was evaluated. Results: Sixty eight patients satisfying the criteria of International League against Rheumatism (ILAR) for Juvenile Idiopathic Arthritis were enrolled during the study period of four consecutive years, their age ranged from 9 months to 15 years. Mean age at onset was 6.45 +- 4.03 years while mean age at diagnosis was 7.60 +- 3.93 years. Polyarticular was the most predominant subtype with 37 (54%) patients, out of these, 9 (24%) were rheumatoid factor positive. An almost equal gender predisposition was observed. Fever and arthritis were the most common presenting symptoms, with only 2 patients presenting with uveitis. Conclusion: The clinico-biochemical characteristics of JIA at the study centre showed a pattern distinct with early onset of disease, high frequency of polyarticular type and a higher rheumatoid factor (QRA) and ANA positivity in girls.

    2013-01-01

    Salivary mucocele is one of the causes of submandibular swelling in dogs and is due to a collection of mucoid saliva that has leaked from a damaged salivary gland. The purpose of this case series report was to describe the clinical and ultrasonographic characteristics of confirmed salivary mucoceles in 13 dogs admitted to the Faculty of Veterinary Medicine at Cairo University. The final diagnosis of salivary mucocele was based on aspirate cytology for all dogs and additional surgical excision for seven dogs. For dogs admitted from 2 weeks to 1 month from the onset of clinical signs, the cervical mucocele appeared as a round echogenic structure with a large volume of central anechoic content. The wall was a clearly identified hyperechoic structure surrounding the gland. For dogs admitted between 1 to 2 months from the onset of clinical signs, the volume of anechoic material appeared less than that seen in the acute cases. The overall appearance of the salivary mucocele was heterogenous. For dogs admitted after 2 months from the onset of clinical signs, the salivary mucocele appeared grainy or mottled, with a heterogenous appearance and a further decrease in anechoic content. For one dog that presented after 3 months from the onset of clinical signs, the salivary mucocele was hard on palpation and appeared hyperechoic with distal acoustic shadowing. Findings from this study indicated that ultrasonographic characteristics of salivary mucoceles in dogs vary depending on the chronological stage of the disease. PMID:23442204

    An accurate diagnosis of osteoporosis and a proper treatment are today recognized to be the most important facts for prevention and for a correct arrangement and treatment of fragility fractures. In the text the Authors describe a case of severe osteoporosis aggravated by 2 femur fractures and 2 periprosthetic fractures occurred in 2 months. In such cases the orthopaedic surgeon needs to formulate first a clinical osteoporotic pattern, than its treatment together with a surgery suitable choice, that has to take into consideration of the bone structural characteristics. In the case described one can note that fractures healing occurred thanks to both an improvement in surgical techniques and antiosteoporotic pharmacological support; in the specific case the Authors used strontium ranelate for its osteoinductive capacity. In our opinion is crucial that the treatment used by orthopaedic surgeons is not related only to the "by-hand" treatment but take into consideration both the underlying disease and the possibility of positively affect bone healing with specific drug therapy.

    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.

    Chronic lymphocytic leukemia (CLL) and myeloproliferative neoplasms (MPN) may occur concomitantly. However, little is known about the pathobiological characteristics and interaction between the neoplastic clones in these rare cases of coinciding malignancies. We retrospectively examined the clinical and biological characteristics of 13 patients with concomitant CLL and MPN--eight primary myelofibrosis (PMF), three essential thrombocytosis (ET), and two polycythemia vera (PV)--who presented to our institution between 1998 and 2014, and tested all patients for MPN-specific aberrations, such as JAK2, MPL and CALR mutations. Along with epidemiological and molecular characterization of this rare condition, we found that JAK2 mutation can be detected 9 years prior to PMF diagnosis, suggesting that PMF clinical phenotype may require several years to develop and CLL/MPN clinical co-occurrence might be sustained by common molecular events. Some features of these patients suggest that pathobiologies of these diseases might be intertwined. PMID:26402369

    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.

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.

    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 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.

    This study aimed to assess the relationships between road traffic injury severity and individual characteristics in Liuzhou, a city in southern China. Data for this study were collected from the Guangxi Public Security Bureau Traffic Police Corps. Multivariate ordinal logistic regression analysis was used. Of all 14,595 individuals involved in accidents, males, motor vehicle drivers, motorcyclists, and those aged 21-45 years accounted for the great proportion of all injuries. Children, the elderly, pedestrians, farmers and migrant workers, unemployed people, and novice drivers were at higher risk of serious injury in crashes. These findings suggest that individual characteristics (age, modes of transport, profession, driving experience) are strongly related to injury severity. To address road traffic related mortality and injuries, there is a need to develop policy strategies, strengthen road supervision, and improve public consciousness of road safety. PMID:26867372

    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, irrespective of

    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.

    Recently, longitudinal stent deformation (LSD) has been reported increasingly. Even though the reported cases included almost all stent designs, most cases were seen in the Element™ stent design (Boston Scientific, Natick, MA, USA). It is considered that stent design, lesion and procedural characteristics play a role in the etiology of LSD. Yet, the effect of LSD on long-term clinical outcomes has not been studied well. Element stents implanted between January 2013 and April 2015 in our hospital were examined retrospectively. Patients were grouped into two according to the presence of LSD, and their clinical, lesion and procedural characteristics were studied. Twenty-four LSD's were detected in 1812 Element stents deployed in 1314 patients (1.83 % of PCI cases and 1.32 % of all Element stents). LMCA lesions (16.7 % vs 1.6 %, p LSD than in cases without it. In addition, the number of stents, stent inflation pressure and the use of post-dilatation were significantly different between the two groups. Two patients had an adverse event during the follow-up period. LSD is a rarely encountered complication, and is more common in complex lesions such as ostial, bifurcation and LMCA lesions. The use of extra-support guiding catheter, extra-support guidewires and low stent inflation pressure increases the occurrence of LSD. Nevertheless, with increased awareness of LSD and proper treatment, unwanted long-term outcomes can be successfully prevented. PMID:27198891

    Full Text Available The aim of this study was to investigate the association between image characteristics on preoperative chest CT and severe pleural adhesion during surgery in lung cancer patients. We included consecutive 124 patients who underwent lung cancer surgeries. Preoperative chest CT was retrospectively reviewed to assess pleural thickening or calcification, pulmonary calcified nodules, active pulmonary inflammation, extent of emphysema, interstitial pneumonitis, and bronchiectasis in the operated thorax. The extent of pleural thickening or calcification was visually estimated and categorized into two groups: localized and diffuse. We measured total size of pulmonary calcified nodules. The extent of emphysema, interstitial pneumonitis, and bronchiectasis was also evaluated with a visual scoring system. The occurrence of severe pleural adhesion during lung cancer surgery was retrospectively investigated from the electrical medical records. We performed logistic regression analysis to determine the association of image characteristic on chest CT with severe pleural adhesion. Localized pleural thickening was found in 8 patients (6.5%, localized pleural calcification in 8 (6.5%, pulmonary calcified nodules in 28 (22.6%, and active pulmonary inflammation in 22 (17.7%. There was no patient with diffuse pleural thickening or calcification in this study. Trivial, mild, and moderate emphysema was found in 31 (25.0%, 21 (16.9%, and 12 (9.7% patients, respectively. Severe pleural adhesion was found in 31 (25.0% patients. The association of localized pleural thickening or calcification on CT with severe pleural adhesion was not found (P = 0.405 and 0.107, respectively. Size of pulmonary calcified nodules and extent of emphysema were significant variables in a univariate analysis (P = 0.045 and 0.005, respectively. In a multivariate analysis, moderate emphysema was significantly associated with severe pleural adhesion (odds ratio of 11.202, P = 0.001. In conclusion

    Background and Objectives The epidermoid cyst is a common benign disease of the skin caused by inflammation of hair cortex follicles and proliferation of epidermal cells within the dermis or superficial subcutaneous tissue. The purpose of this study was to investigate the characteristics of epidermoid cysts of the external auditory canal (EAC) by analyzing the clinical and radiologic features. Subjects and Methods The clinical records were retrospectively reviewed for patients diagnosed with epidermoid cyst of the EAC from March 2004 to December 2013. The epidermoid cysts were diagnosed clinically by endoscopy and microscopy examinations and by temporal bone CT images, and were confirmed by histopathologic examination. Characteristics of epidermoid cysts in bony EAC and cartilaginous EAC were compared. Results Eight patients had an epidermoid cyst in the bony EAC and nine patients had one in the cartilaginous EAC. Swelling and otalgia were common symptoms, but 47% of cysts were found incidentally. The mean age of patients was 49.6 years (age range, 26-67 years) in the bony EAC cases and 26.1 years (age range, 6-57 years) in the cartilaginous EAC cases. The mean size of the epidermoid cyst was 3.50 mm (size range, 2-7 mm) in the bony EAC cases and 9.55 mm (size range, 2-20 mm) in the cartilaginous EAC cases. Conclusions Comparison of epidermoid cysts of the bony EAC and the cartilaginous EAC revealed that epidermoid cysts of the bony EAC is usually found incidentally, arose in older patients and had smaller size.

    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. PMID:26646576

    Craniosynostosis, the premature closure of cranial sutures, is a common craniofacial disorder with heterogeneous etiology and appearance. The purpose of this study was to investigate the clinical and molecular characteristics of craniosynostoses in Hungary, including the classification of patients and the genetic analysis of the syndromic forms. Between 2006 and 2012, 200 patients with craniosynostosis were studied. Classification was based on the suture(s) involved and the associated clinical features. In syndromic cases, genetic analyses, including mutational screening of the hotspot regions of the FGFR1, FGFR2, FGFR3, and TWIST1 genes, karyotyping and FISH study of TWIST1, were performed. The majority (88%) of all patients with craniosynostosis were nonsyndromic. The sagittal suture was most commonly involved, followed by the coronal, metopic, and lambdoid sutures. Male, twin gestation, and very low birth weight were risk factors for craniosynostosis. Syndromic craniosynostosis was detected in 24 patients. In 17 of these patients, Apert, Crouzon, Pfeiffer, Muenke, or Saethre-Chotzen syndromes were identified. In one patient, multiple-suture craniosynostosis was associated with achondroplasia. Clinical signs were not typical for any particular syndrome in six patients. Genetic abnormalities were detected in 18 syndromic patients and in 8 relatives. In addition to 10 different, known mutations in FGFR1,FGFR2 or FGFR3, one novel missense mutation, c.528C>G(p.Ser176Arg), was detected in the TWIST1 gene of a patient with Saethre-Chotzen syndrome. Our results indicate that detailed clinical assessment is of paramount importance in the classification of patients and allows indication of targeted molecular testing with the highest possible diagnostic yield.

    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.

    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.

    Objective This study tested the new DSM-5 severity criterion for binge eating disorder (BED) based on frequency of binge-eating in a clinical sample. This study also tested overvaluation of shape/weight as an alternative severity specifier. Method Participants were 834 treatment-seeking adults diagnosed with DSM-5 BED using semistructured diagnostic and eating-disorder interviews. Participants sub-grouped based on DSM-5 severity levels and on overvaluation of shape/weight were compared on demographic and clinical variables. Results Based on DSM-5 severity definitions, 331 (39.7%) participants were categorized as mild, 395 (47.5%) as moderate, 83 (10.0%) as severe, and 25 (3.0%) as extreme. Analyses comparing three (mild, moderate, and severe/extreme) severity groups revealed no significant differences in demographic variables or body mass index (BMI). Analyses revealed significantly higher eating-disorder psychopathology in the severe/extreme than moderate and mild groups and higher depression in moderate and severe/extreme groups than the mild group; effect sizes were small. Participants characterized with overvaluation (N = 449; 54%) versus without overvaluation (N = 384; 46%) did not differ significantly in age, sex, BMI, or binge-eating frequency, but had significantly greater eating-disorder psychopathology and depression. The robustly greater eating-disorder psychopathology and depression levels (medium-to-large effect sizes) in the overvaluation group was observed without attenuation of effect sizes after adjusting for ethnicity/race and binge-eating severity/frequency. Conclusions Our findings provide support for overvaluation of shape/weight as a severity specifier for BED as it provides stronger information about the severity of homogeneous groupings of patients than the DSM-5 rating based on binge-eating.

    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. PMID:27433120

    Little is known concerning the specific clinical characteristics of patients in persistent vegetative states (PVS). Fifty-one patients from four nursing homes, approximately 3% of the total patients, were identified as being in a PVS. The mean age of the patients was 64.8 +/- 3.2 years (range, 19 to 96 years) and the mean duration of the PVS was 3.3 +/- 5.0 years (range, 1 to 16.8 years), with 13 patients' PVS being longer than 5 years. Cerebrovascular accidents and dementia were the most common causes of the PVS, accounting for 32 of the cases (63%). In the younger patients cerebral trauma secondary to motor vehicle accidents was the most common cause. All 51 patients were fed via tube feeding and 35 patients had urinary catheters (75%). All patients were receiving daily medications, with greater than 50% taking daily vitamins. Over 30% were taking digitalis and/or diuretics and over 32% were taking H2 blockers. Transfer of patients to an acute care hospital was not uncommon, with 31 patients (61%) requiring 63 acute care hospitalizations during their stay in the nursing home. As expected, infections were the most common reason for acute care hospitalization, although 15 of the patients were hospitalized for surgical procedures. Another common problem encountered by the patients was pressure sores, with 78% of patients requiring specific therapy for at least one pressure sore. Surprisingly, only 27 (53%) of 51 patients had a specific resuscitation status designation in the medical chart, and neither presence of a chart designation nor specific resuscitation order was related to the patient's age or the cause or duration of PVS. From these data it would appear that clinical characteristics of patients in PVS are variable. Some patients are young, others are old. The cause varies from cerebrovascular accidents to cerebral trauma. Survival may be prolonged; complications are not uncommon, with some patients requiring acute care hospitalization. PMID:2025140

    Conclusion: The prevalence of bacterial infection in patients with NTDT was found to be moderate. Time after splenectomy >10 years, deferoxamine therapy, and iron overload may be clinical risk factors for severe bacterial infection in patients with NTDT. Bacterial infection should be recognized in splenectomized patients with NTDT, particularly those who have an iron overload.

    2014-01-01

    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.

    Full Text Available Objective: In this study, we aimed to evaluate clinical and laboratory characteristics of patients with Kawasaki disease (KD in Konya region of Turkey. 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.

  2. Clinical and molecular characteristics of pyometra in female dogs.

    Pyometra is a common disease of female dogs. In Sweden, where approximately 90% of the dog population is intact (not neutered), nearly 25% of all female dogs are diagnosed with the disease before 10 years of age. In certain high-risk breeds, this risk of developing pyometra exceeds 50%. Various clinical signs associated with the genital tract as well as with systemic disease are present in dogs with pyometra. A frequent and serious consequence of the uterine infection is endotoxaemia and progression into the systemic inflammatory response syndrome (SIRS), or sepsis, and the disease is then regarded as a medical emergency. Acute phase proteins and inflammatory markers associated with SIRS and with the outcome as measured by length of hospitalization have been identified in blood samples. Recently, the inflammatory response in infected uterine tissue during pyometra has been more closely explored. The expression of many genes associated with chemokines, cytokines, inflammatory cell extravasation, anti-bacterial action, the complement system and innate immune responses and also a large panel of proteases are upregulated in the uterine tissue in pyometra. Products of certain upregulated genes may be detected systemically and used for diagnostic or prognostic purposes provided that tests are developed in the future. More knowledge of the complex local and systemic inflammatory response in pyometra may allow identification of novel disease biomarkers or future targets for treatment. In this article, clinical as well as molecular characteristics of the disease are reviewed. PMID:23279529

    In each of the studied 124 pairs, a twin A was distinguished (the patient with manifest symptoms in the discordant pairs, or more seriously affected twin in concordant pairs) and twin B--its partner. It was demonstrated that the order of birth, differences in the weight at birth, periodization of development do not correlate with the differences in the clinical expression of schizophrenia. Such unfavourable factors as asphyxia, complications during delivery, severe somatic illnesses had a certain tendency to accumulate in twin A. The most distinct correlation was found between the traits of a premorbid personality and the eventual intrapair differences in the severeity of schizophrenia. Twin A in the majority of the cases was more excitable in childhood, had more fears, slept worse, and had a poor appetite. The twin A by its premorbid traits was generally characterized by prevalent asthenic features, withdrawal signs and a more dysharmonic type of personality. PMID:7188820

    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. Trial registration COMPASS; registered as NCT00301145 at clinicaltrials.gov.

    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

    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

    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 BACKGROUND OF THE STUDY Hyponatraemia is a commonly encountered plasma electrolyte abnormality noticed in the patients admitted to ICU, which has a diverse variety of manifestations. It can lead to a wide spectrum of clinical symptoms, from subtle to severe or even life-threatening and is associated with increased mortality and morbidity. OBJECTIVES To study the clinical profile at different levels of hyponatraemia in ICU patients and its clinical outcome at different levels. METHODOLOGY A retrospective descriptional study was done at Intensive Care Unit of Dr. B.R. Ambedkar Medical College and Hospital during the period from April 2015 to March 2016 among the patients having serum sodium levels less than 135 mEq/L. RESULTS Commonly involved age group is between 50 to 70 years. Severe form of Hyponatraemia is seen in elderly males. The most common underlying predisposing factor for hyponatraemia in our case series was sepsis (26% followed by gastrointestinal fluid loss (15.5%, diabetic ketoacidosis (10% and cirrhosis of liver (10%. Mortality was highest with severe hyponatraemia (10.5% who had pulmonary sepsis, metabolic encephalopathy, diabetic ketoacidosis and cirrhosis of liver. CONCLUSIONS Hyponatraemia is one of the good predictor of ICU mortality in association with wide variety of systemic diseases and wide spectrum of clinical profile.

    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.

    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.

    Full Text Available OBJECTIVES: Septic pulmonary embolism caused by a Klebsiella (K. pneumoniae liver abscess is rare but can cause considerable morbidity and mortality. However, clinical information regarding this condition is limited. This study was conducted to elucidate the full disease spectrum to improve its diagnosis and treatment. METHOD: We reviewed the clinical characteristics, imaging findings, and clinical courses of 14 patients diagnosed with septic pulmonary embolism caused by a K. pneumoniae liver abscess over a period of 9 years. RESULTS: The two most prevalent symptoms were fever and shortness of breath. Computed tomography findings included a feeding vessel sign (79%, nodules with or without cavities (79%, pleural effusions (71%, peripheral wedge-shaped opacities (64%, patchy ground-glass opacities (50%, air bronchograms within a nodule (36%, consolidations (21%, halo signs (14%, and lung abscesses (14%. Nine (64% of the patients developed severe complications and required intensive care. According to follow-up chest radiography, the infiltrates and consolidations were resolved within two weeks, and the nodular opacities were resolved within one month. Two (14% patients died of septic shock; one patient had metastatic meningitis, and the other had metastatic pericarditis. CONCLUSION: The clinical presentations ranged from insidious illness with fever and respiratory symptoms to respiratory failure and septic shock. A broad spectrum of imaging findings, ranging from nodules to multiple consolidations, was detected. Septic pulmonary embolism caused by a K. pneumoniae liver abscess combined with the metastatic infection of other vital organs confers a poor prognosis.

    Full Text Available Introduction The relationship between severe clinical manifestations of visceral leishmaniasis (VL and immune response profiles has not yet been clarified, despite numerous studies on the subject. This study aimed to investigate the relationship between cytokine profiles and the presence of immunological markers associated with clinical manifestations and, particularly, signs of severity, as defined in a protocol drafted by the Ministry of Health (Brazil. Methods We conducted a prospective, descriptive study between May 2008 and December 2009. This study was based on an assessment of all pediatric patients with VL who were observed in a reference hospital in Maranhão. Results Among 27 children, 55.5% presented with more than one sign of severity or warning sign. Patients without signs of severity or warning signs and patients with only one warning sign had the highest interferon-gamma (IFN-γ levels, although their interleukin 10 (IL-10 levels were also elevated. In contrast, patients with the features of severe disease had the lowest IFN-γ levels. Three patients who presented with more than two signs of severe disease died; these patients had undetectable interleukin 2 (IL-2 and IFN-γ levels and low IL-10 levels, which varied between 0 and 36.8pg/mL. Conclusions Our results showed that disease severity was associated with low IFN-γ levels and elevated IL-10 levels. However, further studies with larger samples are needed to better characterize the relationship between disease severity and cytokine levels, with the aim of identifying immunological markers of active-disease severity.

    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.

    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...

  2. 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 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.

    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.

  5. Computerized tomography (CT), electroencephalography (EEG), and clinical symptoms in severe cranio-cerebral injuries

    International Nuclear Information System (INIS)

    In the first six months of 1977 156 patients with craniocerebral injuries underwent computerized tomography. Twelve had severe deficits which led to neurosurgical interventions. Only five had space-occupying haematomas. Ct was useful in detecting neurosurgical complications, whereas EEG was useful in staging the severity of the trauma. The two methods, the functional one of EEG and the morphological one of CT, are complementary, especially with regard to the posttraumatic course. The clinical symptoms are reflected by EEG better than by CT. (author)

    Previous studies suggest that altered corneal temperature may be a feature of schizophrenia, but the association between major depressive disorder (MDD) and corneal temperature has yet to be assessed. The aim of this study is to investigate whether eye temperature is different among MDD patients than among healthy individuals. We used a thermographic camera to measure and compare the temperature profile across the corneas of 16 patients with MDD and 16 age- and sex-matched healthy subjects. We found that the average corneal temperature between the two groups did not differ statistically, although clinical severity correlated positively with right corneal temperature. Corneal temperature may be an indicator of clinical severity in psychiatric disorders, including depression.

    Full Text Available Abstract Background The tcdA-negative variant (A-B+ of Clostridium difficile is prevalent in East Asian countries. However, the risk factors and clinical characteristics of A-B+C. difficile infections (CDI are not clearly documented. The objective of this study was to investigate these characteristics. Methods From September 2008 through January 2010, the clinical characteristics, medication history and treatment outcomes of CDI patients were recorded prospectively. Toxin characterization and antibiotic susceptibility tests were performed on stool isolates of C. difficile. Results During the study period, we identified 22 cases of CDI caused by tcdA-negative tcdB-positive (A-B+ strains and 105 cases caused by tcdA-positive tcdB-positive (A+B+ strains. There was no significant difference in disease severity or clinical characteristics between the two groups. Previous use of clindamycin and young age were identified as significant risk factors for the acquisition of A-B+ CDI (OR = 4.738, 95% CI 1.48–15.157, p = 0.009 and OR = 0.966, 95% CI 0.935–0.998, p = 0.038, respectively in logistic regression. Rates of resistance to clindamycin were 100% and 69.6% in the A-B+ and A+B+ isolates, respectively (p = 0.006, and the ermB gene was identified in 17 of 21 A-B+ isolates (81%. Resistance to moxifloxacin was also more frequent in the A-B+ than in the A+B+ isolates (95.2% vs. 63.7%, p = 0.004. Conclusions The clinical course of A-B+ CDI is not different from that of A+B+ CDI. Clindamycin use is a significant risk factor for the acquisition of tcdA-negative variant strains.

    50 patients with autonomous growth hormone excess (48 with adult acromegaly and 2 with gigantism) were studied between 1966 to 1986 (2.38 pts/year). Characteristic clinical presentation, an increase in growth hormone (GH) uninhibited by glucose, and/or hyperphosphemia and hyperhydroxiprolinuria were present in all patients. No cases of hypercalcemia were recorded. Phosphemia was increased in 55.8%, alkaline phosphatases in 61.7%, calciuria in 26.9% and hydroxyprolinuria in 74.2% of the patients. Basal GH was over 5 ng/ml (89.9 DS +/- 170.9) in 42 pts, and in 37 was not suppressed after glucose administration, 38% had an increased (paradoxical response) and 62% a flat response (less than 50% change of basal values). TRH test was performed in 14 patients, 8 presented an increase in GH titer. Hyperprolactinemia was seen in 4 of 12 patients in whom this hormone was measured. The size of the sella turcica was increased in 93%, and although the larger sellar size correlated to higher levels of GH, correlation was not significant. 20% of the pts had rheumatological disease, 14% goiter, 12% cardiac disease, 26.5% had diastolic hypertension and 4% renal lithiasis (hypercalciuric pts). 38% had hyperglycemia with a diabetic glucose tolerance test and 18% had non-diabetic abnormal glucose tolerance test.

    While the incidence of pediatric kidney stones appears to be increasing, little is known about the demographic, clinical, laboratory, imaging, and management variables in this patient population. We sought to describe various characteristics of our stone-forming pediatric population. To that end, we retrospectively reviewed the charts of pediatric patients with nephrolithiasis confirmed by imaging. Data were collected on multiple variables from each patient and analyzed for trends. For body mass index (BMI) controls, data from the general pediatrics population similar to our nephrolithiasis population were used. Data on 155 pediatric nephrolithiasis patients were analyzed. Of the 54 calculi available for analysis, 98 % were calcium based. Low urine volume, elevated supersaturation of calcium phosphate, elevated supersaturation of calcium oxalate, and hypercalciuria were the most commonly identified abnormalities on analysis of 24-h urine collections. Our stone-forming population did not have a higher BMI than our general pediatrics population, making it unlikely that obesity is a risk factor for nephrolithiasis in children. More girls presented with their first stone during adolescence, suggesting a role for reproductive hormones contributing to stone risk, while boys tended to present more commonly at a younger age, though this did not reach statistical significance. These intriguing findings warrant further investigation. PMID:26467033

    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.

    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.

    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.

    The fundamental dosimetric characteristics of commercially available metal oxide semiconductor field effect transistor (MOSFET) detectors were studied for clinical electron beam irradiations. MOSFET showed excellent linearity against doses measured using an ion chamber in the dose range of 20-630cGy. MOSFET reproducibility is better at high doses compared to low doses. The output factors measured with the MOSFET were within +/-3% when compared with those measured with a parallel plate chamber. From 4 to 12MeV, MOSFETs showed a large angular dependence in the tilt directions and less in the axial directions. MOSFETs do not show any dose-rate dependence between 100 and 600MU/min. However, MOSFETs have shown under-response when the dose per pulse of the beam is decreased. No measurable effect in MOSFET response was observed in the temperature range of 23-40 degrees C. The energy dependence of a MOSFET dosimeter was within +/-3.0% for 6-18MeV electron beams and 5.5% for 4MeV ones. This study shows that MOSFET detectors are suitable for dosimetry of electron beams in the energy range of 4-18MeV. PMID:19128995

    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 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.

  20. Correlation between CT features and clinical severity stratification in acute pulmonary embolism

    International Nuclear Information System (INIS)

    Objective: To analyze the correlation factors between CT imaging features of pulmonary embolism (PE) and clinical severity stratification, to explore the value of CT pulmonary angiography (CTPA) in acute PE severity stratification. Methods: According to the clinical severity, 48 patients with acute PE proved by CTPA were classified into two groups, including 21 critical and 27 non-critical patients. Embolism index, ratio of central pulmonary involvement, ratio of right ventricle maximum minor axis (RVMMA) to left ventricle maximum minor axis (LVMMA), namely RV: LV, dilation of main pulmonary and/or right pulmonary trunk, and dilation of bronchial arteries in both groups were analyzed comparatively. The correlation factors between CT imaging features and PE clinical severity stratification were explored. The correlation between RV: LV and embolism index of 48 patients was analyzed. Results: Pulmonary embolism index (22.0%-85.0%, median 38.0%), ratio of central pulmonary involvement (42.5%), RV: LV (0.90-1.90, median 1.30), dilation of pulmonary artery (14 eases), and dilation of bronchial artery (8 eases) in critical group (21 eases) were higher than those corresponding factors (5%-48%, median 21.5%, 31.25%, 0.80-1.40, median 1.00, 5 cases, and 3 cases) in non-critical group (27 cases) (Z=4.27, χ2=5.40, Z=2.58, χ2=11.45, χ2=4.87, P<0.05). There was remarkable correlation between RV: LV and embolism index (r=0.61, P<0.05). Conclusion: CTPA is feasible in evaluating PE severity stratification. The higher the embolism index, RV:LV, and the ratio of central pulmonary involvement, the higher probability of serious hemodynamic changes in PE patients. (authors)

    This Indonesian study evaluates associations between near-miss status/death with maternal demographic, health care characteristics, and obstetrical complications, comparing results using retrospective and prospective data. The main outcome measures were obstetric conditions and socio-economic factors to predict near-miss/death. We abstracted all obstetric admissions (1,358 retrospective and 1,240 prospective) from two district hospitals in East Java, Indonesia between 4/1/2009 and 5/15/2010. Prospective data added socio-economic status, access to care and referral patterns. Reduced logistic models were constructed, and multivariate analyses used to assess association of risk variables to outcome. Using multivariate analysis, variables associated with risk of near-miss/death include postpartum hemorrhage (retrospective AOR 5.41, 95 % CI 2.64-11.08; prospective AOR 10.45, 95 % CI 5.59-19.52) and severe preeclampsia/eclampsia (retrospective AOR 1.94, 95 % CI 1.05-3.57; prospective AOR 3.26, 95 % CI 1.79-5.94). Associations with near-miss/death were seen for antepartum hemorrhage in retrospective data (AOR 9.34, 95 % CI 4.34-20.13), and prospectively for poverty (AOR 2.17, 95 % CI 1.33-3.54) and delivering outside the hospital (AOR 2.04, 95 % CI 1.08-3.82). Postpartum hemorrhage and severe preeclampsia/eclampsia are leading causes of near-miss/death in Indonesia. Poverty and delivery outside the hospital are significant risk factors. Prompt recognition of complications, timely referrals, standardized care protocols, prompt hospital triage, and structured provider education may reduce obstetric mortality and morbidity. Retrospective data were reliable, but prospective data provided valuable information about barriers to care and referral patterns. PMID:25656716

    Full Text Available OBJECTIVES: Coronary artery disease (CAD severity is associated with patient prognosis. However, few efficient scoring systems have been developed to screen severe CAD in patients with stable angina and suspected CAD before coronary angiography. Here, we present a novel scoring system for CAD severity before elective coronary angiography. METHODS: Five hundred fifty-one patients with stable angina who were admitted for coronary angiography were enrolled in this study. Patients were divided into training (n = 347 and validation (n = 204 cohorts. Severe CAD was defined as having a Gensini score of 20 or more. All patients underwent echocardiography (ECG to detect ejection fraction and aortic valve calcification (AVC. Multivariable analysis was applied to determine independent risk factors and develop the scoring system. RESULTS: In the training cohort, age, male sex, AVC, abnormal ECG, diabetes, hyperlipidemia, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol were identified as independent factors for severe CAD by multivariable analysis, and the Severe Prediction Scoring (SPS system was developed. C-indices of receiver operating characteristic (ROC curves for severe CAD were 0.744 and 0.710 in the training and validation groups, respectively. The SPS system also performed well during calibration, as demonstrated by Hosmer-Lemeshow analysis in the validation group. Compared with the Diamond-Forrester score, the SPS system performed better for severe CAD prediction before elective coronary angiography. CONCLUSIONS: Severe CAD prediction was achieved by analyzing age, sex, AVC, ECG, diabetes status, and lipid levels. Angina patients who achieve high scores using this predicting system should undergo early coronary angiography.

    Abstract Primary gastric lymphoma (PGL) is the most common extranodal non-Hodgkin lymphoma. This retrospective study aimed to analyze the clinical characteristics, prognostic factors, and roles of different treatment modalities in patients with PGL. From January 2003 to November 2014, 165 patients who were diagnosed with PGL at West China Hospital were enrolled in this study. The clinical features, treatment, and follow-up information were analyzed. In this study, diffuse large B-cell lymphoma (DLBCL) (108, 65.5%) and mucosa-associated lymphoid tissue (MALT) lymphoma (52, 31.5%) were two predominant histological subtypes. One-year and 5-year overall survival (OS) rates of all patients were 95.2% and 79.5%, respectively; in whom 110 (66.7%) underwent surgery, 110 (66.7%) received chemotherapy, 12 (7.3%) received radiotherapy, and 10 (6.1%) received Helicobacter pylori eradication. And 75 patients (45.5%) were treated with at least 2 different types of therapies. Elevated lactic dehydrogenase (LDH) levels, poor performance status (PS), advanced stage, International Prognostic Index (IPI) score ≥3, conservative treatment, and high-grade histological subtype were associated with worse prognosis in univariate analysis. Cox regression analysis showed that LDH levels, PS, staging, and histological subtype were independent predictors of survival outcomes. In the DLBCL type, 5-year OS was significantly better in the surgically treated group (80.1%) than that of patients conservatively treated (49.8%) (P = 0.001). Surgical treatment had almost no impact on OS in the MALT type than conservative treatment (P = 0.597). The proportion of patients received conservative treatment increased from 4.5% in period 1 to 51.7% in period 4. High LDH levels, poor PS, advanced staging, and malignant pathological type at diagnosis are significantly associated with poor OS. Our data suggest that surgery is superior in prognosis over conservative treatment in the DLBCL type, but not

    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.

    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.

    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.

    Full Text Available Abstract Background Autism Spectrum Conditions (ASCs are characterized by a high degree of clinical heterogeneity, but the extent to which this variation represents a severity gradient versus discrete phenotypes is unclear. This issue has complicated genetic studies seeking to investigate the genetic basis of the high hereditability observed clinically in those with an ASC. The aim of this study was to examine the possible clustering of symptoms associated with ASCs to determine whether the observed distribution of symptom type and severity supported either a severity or a symptom subgroup model to account for the phenotypic variation observed within the ASCs. Methods We investigated the responses of a group of adults with higher functioning ASCs on the fifty clinical features examined in the Autism Spectrum Quotient, a screening questionnaire used in the diagnosis of higher functioning ASCs. In contrast to previous studies we have used this instrument with no a priori assumptions about any underlying factor structure of constituent items. The responses obtained were analyzed using complete linkage hierarchical cluster analysis. For the members of each cluster identified the mean score on each Autism Spectrum Quotient question was calculated. Results Autism Spectrum Quotient responses from a total of 333 individuals between the ages of 16.6 and 78.0 years were entered into the hierarchical cluster analysis. The four cluster solution was the one that generated the largest number of clusters that did not also include very small cluster sizes, defined as a membership comprising 10 individuals or fewer. Examination of these clusters demonstrated that they varied in total Autism Spectrum Quotient but that the profiles across the symptoms comprising the Autism Spectrum Quotient did not differ independently of this severity factor. Conclusion These results are consistent with a unitary spectrum model, suggesting that the clinical heterogeneity observed

    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.

    In the United States, substance users who voluntarily (VO) elect to receive treatment and substance users who are court-mandated (CM) to receive treatment typically obtain care within the same facilities. Little is known about the clinical characteristics that differentiate these individuals. The current study provides rates of specific DSM-IV Axis I and Axis II psychiatric and substance use disorders, comorbidities, childhood trauma, motivation, and other clinical and demographic characteristics as a function of referral status, among individuals in residential substance use treatment (463 participants, M age=43.3; 69.7% male; 88.4% African American). Participants were interviewed and diagnosed using the Structure Clinical Interview for DSM-IV and the Diagnostic Interview for Personality Disorders. Within our sample, VO individuals, as compared to CM individuals had significantly higher rates of psychiatric disorders (68.7% versus 55.2%, respectively), including mood disorders, major depressive disorder, generalized anxiety disorder, and borderline personality disorder. Additionally, they were significantly more likely to have alcohol dependence (43.0% versus 20.8%) and cocaine dependence (66.5% versus 48.9%). Elevated rates of comorbidities and childhood abuse were also observed among VO individuals, while motivation did not differ as a function of referral status. Overall, VO individuals appeared to have more severe problems than their CM counterparts which may suggest that they require more intensive or different types of treatment. PMID:23380487

    Context: Free fatty acids (FFAs) and triglycerides (TGs) are altered postburn, but whether these alterations are associated with postburn outcomes is not clear. Objective: The aim of the present study was to analyze lipid metabolic profiles in pediatric burn patients and to correlate these profiles with patient outcomes and hospital courses. Design and Setting: We conducted a prospective cohort study at an academic pediatric hospital burn center. Patients: Our study included 219 pediatric burn patients. Main Outcome Measures: Patients were stratified according to their plasma TG and FFA levels. Main patient outcomes, such as postburn morbidity and mortality, and clinical metabolic markers were analyzed. Results: All groups were similar in demographics and injury characteristics. Patients with elevated TGs had significantly worse clinical outcomes associated with increased acute-phase protein synthesis indicating augmented inflammation and hypermetabolism, whereas increased FFAs did not seem to profoundly alter postburn outcomes. Conclusions: Elevated TGs, but not FFAs, postburn are associated with worsened organ function and clinical outcomes. PMID:23150682

    Full Text Available Clinical manifestations of hepatitis A virus (HAV infection vary from mild to fulminant hepatic failure (FHF in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA and evaluated predictive factors for severe acute hepatitis (s-AH.We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128. Other patients were defined as mild acute hepatitis (m-AH (n = 642. Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer.In a multivariate analysis, age (HR = 1.042, P = 0.041, peak creatinine (HR = 4.014, P = 0.001, bilirubin (HR = 1.153, P = 0.003, alanine aminotransferase (ALT (HR = 1.001, P < 0.001, initial lactate dehydrogenase (LDH (HR = 1.000, P = 0.045 and total cholesterol (HR = 0.978, P < 0.001 were independent factors for s-AH. Serum HAV RNA was detected in 20/20 (100% patients with s-AH and 22/28 (78.6% patients with m-AH. In a multivariate analysis of the 48 patients who were tested for HAV RNA, peak ALT (HR = 1.001, P = 0.004 and HAV RNA titer (HR = 2.076, P = 0.012 were independent factors for s-AH.Clinical factors including age, peak creatinine, bilirubin, ALT, initial LDH and total cholesterol were independent factors for s-AH in a multivariate analysis. In particular, HAV load strongly correlated with the severity of hepatitis A.

    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

    Nitrogen isotopic ratios of crude oils with different physical and chemical properties in several basins of China have been measured and their geochemistry has been studied elementally combined with molecular organic geochemistry methods. The data indicate that δ15N is in the range of -6‰-20‰. They vary with the oils in different sedimentary types of basins. The oils forming in the limnic environment have lower δ15N with the value of about 1‰-5‰ whereas the oils in saline or semi-saline environment have higher δ15N, with most samples being above 10‰ and some exceeding 17‰. The average nitrogen isotopic ratio of oils from the Ordovician formation in the Tarim Basin is the lowest, with most samples having δ15N below zero, which reflects possibly the characteristic of the oils originating mainly from the organic matter formed in marine carbonate sedimentary environment. The δ15N distribution can be altered by fractionation. It increases obviously because of biodegradation and decreases during hydrocarbon migration. However, the effect of nitrogen isotopic fractionation in the short distance migration is unconspicuous.

    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 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.

    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

    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.

    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.

    2015-01-01

    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. PMID:26229695

    Psoriasis is a chronic skin disease associated with problems in body image and self-esteem and feelings of stigma and shame. The aim of this study was to analyse the clinical extent of psoriasis and its association with psychological distress, and to compare the psychopathological traits in early-onset (type I: age of onset 40 years) psoriasis. A total of 140 patients participated in the study; 70 patients with confirmed diagnosis of psoriasis vulgaris and 70 patients as a comparative group. A battery of psychological instruments was used together with an Inventory of life stress events. The severity of psoriasis was assessed by standardized Psoriasis Area and Severity Index measure. The Psoriasis Life Stress Inventory showed the significant correlation with clinical extent of psoriasis and other measures of psychological distress. Patients with late-onset psoriasis had more prominent symptoms of depression compared with the group with early-onset psoriasis and the comparative group. The results of the Minnesota Multiphasic Personality Inventory-201 for the patient group with late-onset psoriasis showed a specific configuration of neurotic triad. PMID:20526541

    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.

    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.

  3. Severe hypoxia induces chemo-resistance in clinical cervical tumors through MVP over-expression

    International Nuclear Information System (INIS)

    Oxygen molecule modulates tumour response to radiotherapy. Higher radiation doses are required under hypoxic conditions to induce cell death. Hypoxia may inhibit the non-homologous end-joining DNA repair through down regulating Ku70/80 expression. Hypoxia induces drug resistance in clinical tumours, although the mechanism is not clearly elucidated. Vaults are ribonucleoprotein particles with a hollow barrel-like structure composed of three proteins: major vault protein (MVP), vault poly(ADP-ribose) polymerase, and telomerase associated protein-1 and small untranslated RNA. Over-expression of MVP has been associated with chemotherapy resistance. Also, it has been related to poor outcome in patients treated with radiotherapy alone. The aim of the present study was to assess the relation of Major Vault Protein expression and tumor hypoxia in clinical cervical tumors. MVP, p53 and angiogenesis, together with tumor oxygenation, were determined in forty-three consecutive patients suffering from localized cervix carcinoma. High MVP expression was related to severe hypoxia compared to low MVP expressing tumors (p = 0.022). Tumors over-expressing MVP also showed increased angiogenesis (p = 0.003). Besides it, in this study we show for the first time that severe tumor hypoxia is associated with high MVP expression in clinical cervical tumors. Up-regulation of MVP by hypoxia is of critical relevance as chemotherapy is currently a standard treatment for those patients. From our results it could be suggested that hypoxia not only induces increased genetic instability, oncogenic properties and metastatization, but through the correlation observed with MVP expression, another pathway of chemo and radiation resistance could be developed

    Full Text Available Background and Design: In this study, we aimed to evaluate the efficacy, safety and side effects of infliximab therapy in patients followed up in our clinic with moderate-severe psoriatic patients unresponsive to conventional therapies.Material and Method: Twenty-six psoriasis patients who were given infliximab therapy in our clinic between years 2006-2008, were retrospectively analyzed for their demographical clinical features, changes in PASI score, duration, efficacy and adverse effects of the therapy. Results: There were 15 female and 11 male psoriasis patients; ages ranging from 18 to 70 years (45.2±12.9. 17 of them were diagnosed as generalize plaque type psoriasis, 2 as eritrodermic psoriasis, 5 as generalize pustular, two of them as palmoplantar pustular psoriasis. Thirteen have associated psoriatic arthritis. All patients received 5 mg/kg intravenous infliximab infusion at weeks 0, 2, and 6, followed by every 8 weeks. Number of infliximab therapy sections was ranging from 2 to 16 and duration of treatment from 1 month to 28 months. Improvement in PASI between pretreatment and after induction therapy was statistically significant (p<0.05. Additional systemic treatment for disease activation was applied to patients receiving infliximab monotherapy at 14.-38. weeks. We observed allergic infusion reactions in 15.4% of the patients. Conclusion: In compatible with data in literature, we found that infliximab therapy provides a rapid clinical response in patients (generalized, eritrodermic and/or pustular psoriasis who are unresponsive to immunosupressive agents or in cases which these treatment modalities cannot be used because of side effects.

    Full Text Available One of the main characteristics of the current pandemic caused by the virus of Influenza A (H1N1 is the presence of non-habitual groups of high risk to develop severe clinical pictures, mainly as a consequence of a complicated serious pneumonia associated to an adult respiratory distress syndrome. This situation may lead the patient to the intensive care unit and could cause his death, although the figures of such cases stay relatively low, in relation to other epidemics of seasonal Influenza. Among those groups are the people between the ages of 10 and 60 years, seemingly healthy, pregnant and postpartum women, and obese and asthmatic patients, but until now a specific medical comorbidity has not been evidenced in the 40 to 50% of the fatal cases. In this work we offer possible answers to why these groups of risk suffer from severe complications of the illness, starting from an analysis of the triad: agent-guest-environment. A group of ideas obtained from the review of medical literature are exposed plus the clinical experience of the authors in the medical care of those sick persons. It is emphasized the necessity of early identification of high risk patients of presenting severe complications, mainly those "hyperimmunes", that we can be able to manage them. It is emphasized that new answers originate new questions. Meanwhile, the whole diagnosis and therapeutic’s arsenal for the prevention and the care of the critical sick persons, should be put on at the patients’ disposition, especially to those ones that required intensive care.

    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.

    Facial psoriasis is often observed in moderate to severe degrees of psoriasis. While we previously demonstrated construct validity of the facial Psoriasis Log-based Area and Severity Index (fPLASI) system for the cross-sectional evaluation of facial psoriasis, its reliability and accuracy to detect clinical improvement has not been confirmed yet. The aim of this study is to analyze whether the fPLASI properly represents the range of improvement for facial psoriasis compared with the existing facial Psoriasis Area and Severity Index (fPASI) after receiving systemic treatments in clinical practice settings. The changing severity of facial psoriasis for 118 patients was calculated by the scales of fPASI and fPLASI between two time points after systemic treatments. Then, percentage changes (ΔfPASI and ΔfPLASI) were analyzed from the perspective of both the Physician's Global Assessment of effectiveness (PGA) and patients' Subjective Global Assessment (SGA). As a result, the distribution of the fPASI was more heavily clustered around the low score range compared with the fPLASI at both first and second visits. Linear regression analysis between ΔfPASI and ΔfPLASI shows that the correlation coefficient was 0.94, and ΔfPLASI represented greater percentage changes than ΔfPASI. Remarkably, degrees of clinical improvement measured by the PGA matched better with ΔfPLASI, while ΔfPASI underestimated clinical improvements compared with ΔfPLASI from treatment-responding groups by the PGA and SGA. In conclusion, the fPLASI represented clinical improvement of facial psoriasis with more sensitivity and reliability compared with the fPASI. Therefore, the PLASI system would be a viable severity measurement method for facial psoriasis in clinical practice.

    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

    Two Phase 3, double-blind, randomized, vehicle-controlled parallel studies evaluated the efficacy and safety of desoximetasone spray 0.25%, a super-potent topical corticosteroid, twice daily vs vehicle spray twice daily for 28 days in adult patients with moderate to severe plaque psoriasis. At baseline and throughout the study, the severity of disease for the psoriatic lesions was assessed using the Physician Global Assessment (PGA) score and a target lesion was assessed using the Total Lesion Severity Score (TLSS). A designated psoriatic plaque lesion was selected as the target lesion upon enrollment and evaluated throughout the study to determine the TLSS. To qualify for study entry, the subject needed to exhibit a PGA score of 3 (moderate) or 4 (severe) for overall disease severity, and a target lesion with an area of at least 5 cm(2) that achieved a combined score TLSS of >=7, with a plaque elevation score of >=3 (at least moderate). The mean % BSA affected by psoriasis ranged from 13%-17% at baseline. In both Phase 3 studies, a statistically significantly greater percentage of subjects in the desoximetasone spray 0.25% compared to vehicle group achieved both Clinical Success and Treatment Success at Day 28. These results, which were the primary efficacy variables, demonstrated superior efficacy in the active study group for both overall improvement of plaque psoriasis (by PGA) and in the individual psoriasis lesion (by TLSS) designated at baseline as the most severely involved plaque (target lesion). Assessment of secondary efficacy variables in both Phase 3 studies showed that subjects receiving desoximetasone Spray 0.25% twice daily exhibited statistically significantly mean changes from Baseline to Day 28 in PGA, TLSS, and % BSA affected when compared to subjects receiving vehicle spray twice daily. Tolerability and safety were assessed at all study visits. No statistically significant differences were observed between study arms and no major safety signals

    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.

    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.

    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.

Complexome profiling recently identified TMEM126B as a component of the mitochondrial complex I assembly complex alongside proteins ACAD9, ECSIT, NDUFAF1, and TIMMDC1.

    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.

    Full Text Available BACKGROUND: Massive wasp stings have been greatly underestimated and have not been systematically studied. The aim of this study was to identify the clinical features and treatment strategies of severe wasp stings. METHODS AND FINDINGS: A multicenter retrospective study was undertaken in 35 hospitals and medical centers including 12 tertiary care hospitals and 23 secondary care hospitals in the Hubei Province, China. The detailed clinical data of 1091 hospitalized wasp sting patients were investigated. Over three-fourths (76.9% of the cases had 10 or more stings and the in-hospital mortality of patients was 5.1%. Forty-eight patients died of organ injury following toxic reactions to the stings, whereas six died from anaphylactic shock. The in-hospital mortality in patients with >10 stings was higher than that of ≤10 stings (5.2% vs. 1.0%, p = 0.02. Acute kidney injury (AKI was seen in 21.0% patients and most patients required blood purification therapy. Rhabdomyolysis was seen in 24.1% patients, hemolysis in 19.2% patients, liver injury in 30.1% patients, and coagulopathy in 22.5% patients. Regression analysis revealed that high creatinine level, shock, oliguria, and anemia were risk factors for death. Blood purification therapy was beneficial for patients with ≥20 stings and delayed hospital admission of patients (≥4 hours after sting. CONCLUSIONS: In China, most patients with multiple wasp stings presented with toxic reactions and multiple organ dysfunction caused by the venom rather than an anaphylactic reaction. AKI is the prominent clinical manifestation of wasp stings with toxic reaction. High creatinine levels, shock, oliguria, and anemia were risk factors for death.

    Sea ice is a key climate factor and it restricts considerably the winter navigation in sever seasons on the Baltic Sea. So determining ice conditions severity and describing ice cover behaviour at severe seasons interests scientists, engineers and navigation managers. The present study is carried out to determine the ice seasons severity degree basing on the ice seasons 1982 to 2015. A new integrative characteristic is introduced to describe the ice season severity. It is the sum of ice extents of the ice season id est the daily ice extents of the season are summed. The commonly used procedure to determine the ice season severity degree by the maximal ice extent is in this research compared to the new characteristic values. The remote sensing data on the ice concentrations on the Baltic Sea published in the European Copernicus Programme are used to obtain the severity characteristic values. The ice extents are calculated on these ice concentration data. Both the maximal ice extent of the season and a newly introduced characteristic - the ice extents sum are used to classify the winters with respect of severity. The most severe winter of the reviewed period is 1986/87. Also the ice seasons 1981/82, 1984/85, 1985/86, 1995/96 and 2002/03 are classified as severe. Only three seasons of this list are severe by both the criteria. They are 1984/85, 1985/86 and 1986/87. We interpret this coincidence as the evidence of enough-during extensive ice cover in these three seasons. In several winters, for example 2010/11 ice cover extended enough for some time, but did not endure. At few other ice seasons as 2002/03 the Baltic Sea was ice-covered in moderate extent, but the ice cover stayed long time. At 11 winters the ice extents sum differed considerably (> 10%) from the maximal ice extent. These winters yield one third of the studied ice seasons. The maximal ice extent of the season is simple to use and enables to reconstruct the ice cover history and to predict maximal ice

    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

    CD74 is expressed on the cell surface of pulmonary macrophages and contributes to macrophage migration inhibitory factor (MIF)-induced inflammatory response in acute lung injury (ALI). A circulating form of CD74 (soluble CD74, sCD74) was recently discovered in autoimmune liver disease. Using two murine ALI models and cells culture, we examined the presence of sCD74 in circulation and alveolar space and preliminarily assessed the biological function of sCD74. The concentrations of sCD74 were increased in serum and bronchoalveolar lavage fluids (BALF) of murine ALI models. The elevated levels of sCD74 in BALF positively correlated with lung permeability and inflammation. In addition, sCD74 is secreted by macrophages in response to MIF stimulation and itself can stimulate the production of inflammatory cytokines. Our clinical study confirmed some findings of basic research. Moreover, we also found Day 3 serum sCD74 levels were associated with worse clinical outcomes. In conclusion, higher serum sCD74 levels may reflect more severe lung injury and may be used to help physicians determine prognosis of acute respiratory distress syndrome (ARDS). PMID:27444250

    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.

    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.

    Intrusion is defined as the axial dislodgment of the tooth into its socket and is considered one of the most severe types of dental trauma. This longitudinal outcome study was undertaken to evaluate clinically and radiographically severely intruded permanent incisors in a population of children and adolescents. All cases were treated between September 2003 and February 2008 in a dental trauma service. Clinical and radiographic data were collected from 12 patients (eight males and four females) that represented 15 permanent maxillary incisors. Mean age at the time of injury was 8 years and 9 months (range 7-14 years and 8 months). Mean time elapsed to follow-up was 26.6 months (range 10-51 months). The analysis of data showed that tooth intrusion was twice as frequent in males. The maxillary central incisors were the most commonly intruded teeth (93.3%), and falling at home was the main etiologic factor (60%). More than half of the cases (53.3%) were multiple intrusions, 73.3% of the intruded teeth had incomplete root formation and 66.6% of the teeth suffered other injuries concomitant to intrusion. Immediate surgical repositioning was the treatment of choice in 66.7% of the cases, while watchful waiting for the tooth to return to its pre-injury position was adopted in 33.3% of the cases. The teeth that suffered additional injuries to the intrusive luxation presented a fivefold increased relative risk of developing pulp necrosis. The immature teeth had six times more chances of presenting pulp canal obliteration that the mature teeth and a lower risk of developing root resorption. The most frequent post-injury complications were pulp necrosis (73.3%), marginal bone loss (60%), inflammatory root resorption (40%), pulp canal obliteration (26.7%) and replacement root resorption (20%). From the results of this study, it was not possible to determine whether the type immediate treatment had any influence on the appearance of sequelae like pulp necrosis and root

    Through the questionnaire survey of 2,000 patients with dysmenorrhea, the clinical characteristics of dysmenorrhea were investigated, and the reference basis for preventing and controlling dysmenorrhea was provided. The results found that the age of menarche, short menstrual cycle, by volume, long period of time has no obvious relationship with the occurrence of dysmenorrhea. Dysmenorrhea main influence factors to feel cold; syndrome (symptoms) characteristics for the actual situation inclusions mainly, with severity, deficiency symptoms more obvious; in different degrees of dysmenorrhea, frequency of belly chills symptoms appear most, and cold coagulation and blood stasis syndrome (symptoms) appear higher frequency; The type of cold coagulation and blood stasis dysmenorrhea was 53.2%. Dysmenorrhea measures to select bed rest most, accounting for 79.6%. For severe dysmenorrhea in patients with drug choice to traditional Chinese combined with western medicine accounted for 43.4%. Selection of Chinese medicine formulations in patients with dysmenorrhea Decoction formulation accounted for the most 26.5%. The survey results, to avoid cold and have a positive effect on the prevention of dysmenorrhea, dysmenorrhea treatment should pay attention to warming channels to dispel cold. PMID:27062802

    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.

    Genomic disorders have been increasingly recognized as a significant source of clinically relevant phenotypes largely fostered by advances in technologies for genome-wide analyses. Molecular and clinical studies of copy number variants involving chromosome 17 began with locus-specific studies of Charcot-Marie-Tooth disease type 1A (CMT1A, OMIM #118220) and hereditary neuropathy with liability to pressure palsies (HNPP, OMIM #162500), which laid the foundation for the paradigm of duplication/deletion and gene-dosage for our understanding of genomic disorders. With the clinical introduction of high-resolution array comparative genomic hybridization (aCGH) the number of recognized genomic disorders including microduplications has been increasing rapidly. A relatively high proportion of disease-associated copy number variants map to chromosome 17. This may result from its unique structural features, such as relative abundance of segmental duplications and interspersed repetitive elements, high gene content, and the presence of dosage-sensitive genes. These genomic rearrangements are mediated by diverse mechanisms including Non-Allelic Homologous Recombination (NAHR), Non-Homologous End-Joining (NHEJ), and Fork Stalling and Template Switching (FoSTeS). We provide specific examples of chromosome 17 microduplications with the emphasis on their phenotype, specific clinical features aiding in their diagnosis, and counseling. PMID:20425816

    2016-03-01

    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

    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.

    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 To evaluate whether early and acquired daily fluid overload (FO), as well as fluctuations in fluid accumulation, were associated with adverse outcomes in critically ill children with severe sepsis. Methods This study enrolled 202 children in a pediatric intensive care unit (PICU) with severe sepsis. Early fluid overload was defined as ≥5% fluid accumulation occurring in the first 24 hours of PICU admission. The maximum daily fluid accumulation ≥5% occurring during the next 6 days in patients with at least 48 hours of PICU stay was defined as PICU-acquired daily fluid overload. The fluctuation in fluid accumulation was calculated as the difference between the maximum and the minimum daily fluid accumulation obtained during the first 7 days after admission. Results Of the 202 patients, 61 (30.2%) died during PICU stay. Among all patients, 41 (20.3%) experienced early fluid overload, including 9 with a FO ≥10%. Among patients with at least 48 hours of PICU stay (n = 154), 36 (23.4%) developed PICU-acquired daily fluid overload, including 2 with a FO ≥10%. Both early fluid overload (AOR = 1.20; 95% CI 1.08–1.33; P = 0.001; n = 202) and PICU-acquired daily fluid overload (AOR = 5.47 per log increase; 95% CI 1.15–25.96; P = 0.032; n = 154) were independent risk factors associated with mortality after adjusting for age, illness severity, etc. However, fluctuations in fluid accumulation were not associated with mortality after adjustment. Length of PICU stay increased with greater fluctuations in fluid accumulation in all patients with at least 48 hours of PICU stay (FO <5%, 5%-10% vs. ≥10%: 4 [3–8], 7 [4–11] vs. 10 [6–16] days; P <0.001; n = 154) and in survivors (4 [3–8], 7 [5–11] vs. 10 [5–15] days; P <0.001; n = 121). Early fluid overload achieved an area under-the-receiver-operating-characteristic curve of 0.74 (95% CI 0.65–0.82; P <0.001; n = 202) for predicting mortality in patients with severe sepsis, with a sensitivity of 67

    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.

    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.

    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.

    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.

    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

    Chronic venous insufficiency (CVI) is a progressive inflammatory disease. Because of its inflammatory nature, several circulating markers were investigated for predicting disease progression. We aimed to investigate simple inflammatory blood markers as predictors of clinical class and disease severity in patients with CVI. Eighty patients with CVI were divided into three groups according to clinical class (grade 1, 2 and 3) and score of disease severity (mild, moderate and severe). The basic inflammatory blood markers [neutrophil, lymphocyte, mean platelet volume (MPV), white blood cell (WBC), platelet, albumin, D-dimer, fibrinogen, fibrinogen to albumin ratio, and neutrophil to lymphocyte ratio] were investigated in each group. Serum neutrophil, lymphocyte, MPV, platelet count, D-dimer and neutrophil to lymphocyte ratio levels were similar among the groups (P > 0.05). Although the serum WBC levels were significant in the clinical severity groups (P < 0.05), it was useless to separate each severity class. However, albumin, fibrinogen and the fibrinogen to albumin ratio were significant predictors of clinical class and disease severity. Especially, the fibrinogen to albumin ratio was detected as an independent indicator for a clinical class and disease severity with high sensitivity and specificity (75% sensitivity and 87.5% specificity for clinical class and 90% sensitivity and 88.3% specificity for disease severity). Serum fibrinogen and albumin levels can be useful parameters to determine clinical class and disease severity in patients with CVI. Moreover, the fibrinogen to albumin ratio is a more sensitive and specific predictor of the progression of CVI. PMID:26650463

    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: 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.

    Congenital syphilis (CS) is a public health burden in both developing and developed countries. We report two cases of CS in premature neonates with severe clinical manifestations; Patient 1 (gestational age 31 weeks, birth weight 1423 g) had disseminated idiopathic coagulation (DIC) while Patient 2 (gestational age 34 weeks and 6 days, birth weight 2299 g) had refractory syphilitic meningitis. Their mothers were single and had neither received antenatal care nor undergone syphilis screening. Both neonates were delivered via an emergency cesarean section and had birth asphyxia and transient tachypnea of newborn. Physical examination revealed massive hepatosplenomegaly. Laboratory testing of maternal and neonatal blood showed increased rapid plasma reagin (RPR) titer and positive Treponema pallidum hemagglutination assay. Diagnosis of CS was further supported by a positive IgM fluorescent treponemal antibody absorption test and large amounts of T. pallidum spirochetes detected in the placenta. Each neonate was initially treated with ampicillin and cefotaxime for early bacterial sepsis/meningitis that coexisted with CS. Patient 1 received fresh frozen plasma and antithrombin III to treat DIC. Patient 2 experienced a relapse of CS during initial antibiotic treatment, necessitating parenteral penicillin G. Treatment was effective in both neonates, as shown by reductions in RPR. Monitoring of growth and neurological development through to age 4 showed no evidence of apparent delay or complications. Without adequate antenatal care and maternal screening tests for infection, CS is difficult for non-specialists to diagnose at birth, because the clinical manifestations are similar to those of neonatal sepsis and meningitis. Ampicillin was insufficient for treating CS and penicillin G was necessary. PMID:26543391

    Full Text Available Background Multiple sclerosis (MS is a chronic, idiopathic and the most common inflammatory demyelinating disease of the central nervous system that progresses to severe disability. Prevalence of MS is 2 - 150 per 100,000 people. The main cause of the disease is not clear and occurs due to a combination of both genetic and environmental factors. Objectives The purpose of this study was to determine the prevalence rate of MS in the northern cities of Khuzestan Province, Iran, as well as to determine the demographic characteristics, initial symptoms at onset, clinical features and the correlation between the above factors with each other. Patients and Methods In this descriptive correlational study, patients were recruited through the MS Society as well as the neurology clinics and departments of hospitals in north cities of Khuzestan Province (Iran. Data were collected through completing a face to face questionnaire and were analyzed using SPSS version 17 and the chi-square test. P value < 0.05 was considered statistically significance. Results A total of 142 patients were participated in this study. Prevalence of MS was 15 per 100,000 people. Seventy-eight percent of the patients had low literacy, and 81% were unemployed. Female to male ratio was 2.08: 1 that became less in younger patients. 69% and 15% of the patients were relapsing remitting and progressive relapsing, respectively. Demographic characteristics of the patients did not show any statistically significant relationship with clinical courses and signs at onset; however, a significant correlation was seen between severe disability and sex (P = 0.001 as well as between severe disability and progressive-relapsing subtype (P = 0.02. Conclusions The prevalence of MS showed an increasing rate of the disease in recent years. Decreasing of the female to male ratio and patients’ low socio-economic level, need more studies. The increasing rate of patients with progressive relapsing feature

    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

    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.

    A comparative characteristic of the methods for radioimmunological and immunofermental control of supporting therapy is given and the mechanisms of digoxin tolerance in cases of treatment of 89 patients with circulatory insufficiency are investigated. Pharmacokinetic parameters were calculated on the basis of bilocular mathematical model following the intravenous injection of 0.5 mg of digoxin. The absence of substantial differences in the methods under consideration is shown but a certain preference is given to the method of immunofermental analysis as it is convenient to be used for the daily control of the glycoside level in case of supporting therapy and investigations of the preparation pharmacokinetics.

    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.

    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.

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

    Laurens Manning

    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.

    Full Text Available Alan Y Ho, Anastasia DimitropoulosDepartment of Psychology, Case Western Reserve University, Cleveland, OH, USAAbstract: Prader–Willi syndrome (PWS is a complex neurodevelopmental disorder caused by an abnormality on the long arm of chromosome 15 (q11–q13 that results in a host of phenotypic characteristics, dominated primarily by hyperphagia and insatiable appetite. 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

    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.

    2009-01-01

    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.

    Intracranial hemangioblastomas are benign vascular tumors. The peak age of incidence is between 20 to 50 years. Hemangioblastomas rarely occur in patients over the age of 65. To our knowledge there is no review of the prevalence and clinical features in an elderly population. We reviewed our 12 year experience with intracranial hemangioblastomas, and characterized the clinical features of hemangioblastomas in patients over the age of 65. We present a 72-year-old man with a cerebellar mass initially thought to be a metastasis as an illustrative case. We reviewed our pathology database and identified all patients with a histopathologically confirmed diagnosis of hemangioblastoma over the last 12 years in a large tertiary adult hospital; all patients were over the age of 18. Of all cases of hemangioblastoma in the last 12 years, six of 77 (7.7%) occurred in patients over the age of 65. All were cerebellar in location, and none were associated with von-Hippel Lindau disease. Hemangioblastomas are uncommon, but not rare, in patients over the age of 65, and should be included in the differential diagnosis of patients presenting with gait ataxia and a cerebellar lesion in this age group.

    The purpose of our study was (1) to analyze the flap tear location, direction of displacement and size on magnetic resonance (MR) imaging, (2) to describe associated knee abnormalities including presence of effusion, synovitis, bone marrow edema pattern or ligamentous tear, and (3) to assess clinical findings found with flap tears, including the pain score, and determine differences between operative and nonoperative groups. 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.)

    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.

    The inflammatory response induced by burn injury contributes to increased incidence of infections, sepsis, organ failure, and mortality. Thus, monitoring post-burn inflammation is of paramount importance but so far there are no reliable biomarkers available to monitor and/or predict infectious complications after burn. As 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 post-burn sepsis, infections, and mortality other outcomes post-burn. Plasma cytokines, acute phase proteins, constitutive proteins, and hormones were analyzed during the first 60 days post injury from 468 pediatric burn patients. Demographics and clinical outcome variables (length of stay, infection, sepsis, multiorgan failure (MOF), and mortality were recorded. A cut-off level for IL-8 was determined using receiver operating characteristic (ROC) analysis. Statistical significance is set at (p<0.05). ROC analysis identified a cut-off level of 234 pg/ml for IL-8 for survival. Patients were grouped according to their average IL-8 levels relative to this cut off 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 (TBSA) burned and incidence of MOF (p<0.001). In the H group IL-8 levels were able to predict sepsis (p<0.002). In the H group, elevated IL-8 was associated with increased inflammatory and acute phase responses compared to the L group (p<0.05). High levels of IL-8 correlated with increased MOF, sepsis, and mortality. These data suggest that serum levels of IL-8 may be a valid biomarker for monitoring sepsis, infections, and mortality in burn patients. PMID:25514427

    AIM: To evaluate 20 adults with intussusception and to clarify the cause, clinical features, diagnosis, and management of this uncommon entity.METHODS: A retrospective review of patients aged >18 years with a diagnosis of intestinal intussusception between 2000 and 2008. Patients with rectal prolapse,prolapse of or around an ostomy and gastroenterostomy intussusception were excluded.RESULTS: There were 20 cases of adult intussusception.Mean age was 47.7 years. Abdominal pain, nausea,and vomiting were the most common symptoms. The majority of intussusceptions were in the small intestine (85%). There were three (15%) cases of colonic intussusception. Enteric intussusception consisted of five jejunojejunal cases, nine ileoileal, and four cases of ileocecal invagination. Among enteric intussusceptions,14 were secondary to a benign process, and in one of these, the malignant cause was secondary to metastatic lung adenocarcinoma. All colonic lesions were malignant. All cases were treated surgically.

  18. A case of clinical Reye syndrome presenting characteristic CT changes

    International Nuclear Information System (INIS)

    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. (author)

    Purpose To evaluate the evolution of nonlesional temporal lobe epilepsy (TLE-NL) in patients treated exclusively with antiepileptic drugs and to elucidate clinical phenotypes related to the prognosis of these patients. Methods Clinical, radiological, and electroencephalographic (EEG) findings in 84 patients with TLE-NL were reviewed. 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 studies with a much larger population are warranted. PMID:27555776

Patients with the 3d genotype and low viral load were registered with cirrhosis of mixed etiologies (HСV+ alcohol. At the cirrhosis Class B for Child-Pugh basic data biochemical parameters were similar in patients with CP-HGA and CP-HGM, but ALT and AST activity, which are significantly higher than observed in patients with CP-HGM. At dismissal, ALT and GGT activities were detected significantly higher in patients with CP-HGM than the CP-HGA. At the cirrhosis Class C for Child-Pugh the baseline, reflecting cholestasis — is total bilirubin, GGT and alkaline phosphatase and were detected significantly higher in the CP-HGA, than with CP-HGM significantly reduced, and thore is no differences between the groups to be discharged from the hospital, in addition to the activity of GGT, which it remained significantly higher in the CP-HGA, than with CP-HGM. Cytolytic activity of enzymes (ALT, AST during the entire period of the disease was observed significantly higher normal values and did not depend on the CP etiology.Conclusion decision. The maximum rate of change of the basic biochemical parameters is observed in patients with cirrhosis of mixed etiologies Class B for Child-Pugh and at the cirrhosis of an alcoholic genesis — in patients with cirrhosis Class C.

    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.

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

    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.

    The immunogenicity of polysaccharides as human vaccines was enhanced by coupling to protein carriers. Conjugation transformed the T cell-independent polysaccharide vaccines of the past to T cell-dependent antigenic vaccines that were much more immunogenic and launched a renaissance in vaccinology. This review discusses the conjugate vaccines for prevention of infections caused by Hemophilus influenzae type b, Streptococcus pneumoniae, and Neisseria meningitidis. Specifically, the characteristics of the proteins used in the construction of the vaccines including CRM, tetanus toxoid, diphtheria toxoid, Neisseria meningitidis outer membrane complex, and Hemophilus influenzae protein D are discussed. The studies that established differences among and key features of conjugate vaccines including immunologic memory induction, reduction of nasopharyngeal colonization and herd immunity, and antibody avidity and avidity maturation are presented. Studies of dose, schedule, response to boosters, of single protein carriers with single and multiple polysaccharides, of multiple protein carriers with multiple polysaccharides and conjugate vaccines administered concurrently with other vaccines are discussed along with undesirable consequences of conjugate vaccines. The clear benefits of conjugate vaccines in improving the protective responses of the immature immune systems of young infants and the senescent immune systems of the elderly have been made clear and opened the way to development of additional vaccines using this technology for future vaccine products.

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

    2016-01-01

    Full Text Available Pseudo-Lennox syndrome (PLS, or atypical benign partial epilepsy of childhood, is a disease from a group of age-related epileptic encephalopathies with a phenomenon of continuous spike-wave activity during slow sleep, which manifests itself as frequent polymorphic focal motor and pseudogeneralized seizures, cognitive impairments, as well as regional and diffuse epileptiform activity on electroencephalogram (EEG by the morphology identical to that of benign epileptiform patterns of childhood. The disease was first described by J. Aicardi and J. J. Chevrie in 1982, based on a study of 7 cases. Its diagnostic complexity is the polymorphism of both epileptic seizures and EEG data, as well as low awareness of the syndrome among physicians and its absence in the international classification of epilepsies. The typical triad of seizures, which occurs in nearly 100 % of patients, encompasses focal motor paroxysms (identical to those as observed in Rolandic epilepsy, atypical absences, and atonic seizures. Seizures in PLS in its active period (generally up to 7–8 years are highly resistant to antiepileptic drugs. Only a few agents have been proven to be effective in PLS; these include valproates, succinimides, benzodiazepines, topiramate, and sulthiame. The frequency of seizures are noted to increase in patients with PLS treated with drugs, such as vigabatrin, gabapentin, lamotrigine, phenobarbital, or phenytoin. The author considers in detail the history of studies of the disease, clinical manifestations, diagnostic criteria, therapeutic approaches, and prognosis.

    The research goal is to determine clinical, endoscopic and morphological signs of chronic duodenitis in children. Materials and methods: The diagnostic value of molecular markers has been revealed by immunohistochemical research of biopsy. It has been received from endoscopic examination of 32 children aged from 3 to 17 years old with chronic duodenitis. Morphometric investigation of markers expression has been carried out by means of analyzing system of digital images of Mikrovizor medical uVizo-103. Results: The index of proliferation has been higher in cells of cover epithelium than in glands. The inductor expression of apoptosis Bax has been poorly expressed in both groups of patients. It has been proved that proliferative processes are predominant in this pathology. Conclusion: It has been found out that proliferation of significant activity in the cover epithelium accompanies the development of preatrophic processes in children with chronic duodenitis. The greater degree of regeneration has been marked in crypts.

    Full Text Available BACKGROUND: Pulmonary hypertension (PH is associated with increased mortality and morbidity. It is frequently associated with cardiopulmonary diseases that are prevalent in African Americans (AAs. However, the prevalence or determinants of PH in the AA population is not known. METHODS: We conducted a cross-sectional study to estimate the prevalence of PH (defined as trans-tricuspid gradient ≥ 35 mm Hg and associated clinical characteristics in AAs using the Jackson Heart Study cohort (n=3,282 who underwent echocardiography and had a measurable trans-tricuspid regurgitant jet. Echocardiography is frequently used for screening for PH despite its limitations in estimating accurate PA systolic pressures. Overall and age-adjusted gender-specific prevalence were estimated and modified Poisson regression was used to identify independent clinical, spirometric, and echocardiographic characteristics associated with PH. RESULTS: The mean age of the study population was 56.1 ± 12.6 years with 67.5% female. The prevalence of PH was 6.8%, with higher prevalence in female AAs (age-adjusted prevalence: Men 4.9%, 95% CI 3.6-6.2%; Women 7.7%, 95% CI 6.6-8.8%. Pulmonary hypertension prevalence increased with age (Prevalence Ratio: 10.0, 95%CI 4.0-25.1, >65 versus <45 years old, presence of obesity, higher pulse pressure, diabetes, obstructive or restrictive spirometry pattern, and severe left heart valvular disease. Also, PH was significantly associated with left atrial size and left ventricular ejection fraction. CONCLUSIONS: Pulmonary hypertension is prevalent in AAs, more in women than in men. The identified cardiopulmonary risk factors that increase the prevalence of PH may assist in diagnosis and management of these at-risk subjects in the AA population.

The primary endpoints were 30-day and 2-year all-cause mortality.Results: A total of 91 consecutive patients with mean age of 79±9 years (52% men underwent TAVI with a median follow-up duration of 16 months (interquartile range of 27.6 months. CAD was present on 46 patients (51%. At 30-day, the incidences of death were similar between CAD and non-CAD patients (9% and 5%, p=0.44, but at 2 years were 50% in CAD patients and 24% in non-CAD patients (crude hazard ratio with CAD, 2.2; 95% confidence interval [CI], 1.1 to 4.6; p=0.04. Adjusting for age, gender, left ventricular ejection fraction and glomerular filtration rate the hazard of death was 2.6-fold higher in patients with CAD (95% CI, 1.1 to 6.0; p=0.03. Elective PCI before TAVI was performed in 13 patients (28% of CAD patients. There were no more adverse events in patients who underwent TAVI+PCI when compared with those who underwent isolated TAVI. Conclusions: In severe symptomatic AS who underwent TAVI, CAD is frequent and adversely impacts long-term outcomes, but not procedure outcomes. In selected patients, PCI before TAVI appears to be feasible and safe.

    Objective To describe the frequency of systemic inflammatory response syndrome (SIRS) criteria in a cohort of patients hospitalised with purulent soft tissue infections and to determine their impact on clinical characteristics, microbiology and outcomes. Methods Retrospective cohort study of adults hospitalised at the West Haven Veteran's Hospital with purulent soft tissue infections between 1 October 2008 and 30 September 2013. Results A total of 173 patients were included with purulent soft tissue infections; 60 patients had no SIRS, 48 had one SIRS and 65 had ≥ 2 SIRS. Most clinical characteristics were similar between the different SIRS groups, although patients with SIRS were more likely to have severe sepsis and acute kidney injury and to already be on antibiotics at the time of hospitalisation. The microbiology of the infections was similar between SIRS groups. All patients received parenteral antibiotics when admitted and the majority of patients in all SIRS categories received antibiotics with broad Gram-negative activity. Outcomes were generally benign for all SIRS groups, although patients with SIRS had a longer length of stay and a trend towards more bacteremia. Conclusions SIRS are common in patients hospitalised with purulent soft tissue infections, although one third had no systemic signs of infection. Severe sepsis and septic shock are rare. Clinical characteristics, microbiology and antibiotic use are similar among patients in different SIRS groups, although the group without SIRS had a shorter hospitalisation and no episodes of bacteremia. Over-use of antibiotics is common in all SIRS categories. PMID:26950290

    To investigate the features of CT, ultrasonography and fundus fluorescein angiography(FFA) of morning glory syndrome, the data on CT, A/B-scan ultrasonography and fundus fluorescein angiography (FFA) were retrospectively analyzed in 8 cases of morning glory syndrome (MGS).Among those cases, 6 were examined with CT, 4 with FFA and 8 with A/B-scan ultrasonography.Results showed that the characteristics of CT, A/B-scan ultrasonography and FFA in MGS included:(1) The attachment spot of optic nerve became thin and vitreous body protruded to the posterior wall of eyeball with a spherical shape on CT image; (2) in the early period of FFA, hypofluorescence appeared on the optic, the abnormal arteriae and veins around the optic papilla were displayed clearly and in the late period, optic disc was stained with fluorescein; (3) on B-scan ultrasonogram, the vitreous cavity extended to the posterior pole and optic papilla, and projected to the basal part of muscle cones and thus the posterior part of vitreous cavity looked like an upside-down bottleneck. Sometimes the echogenic band of retinal detachment could also be seen. On A-scan ultrasonogram, both vitreous cavity and bottleneck showed no ultrasonic echoes and presented a base line without any evident wave crest. It is concluded that CT, A/B-scan ultrasonography and FFA could show the imageological features of MGS from different aspects, which helps clinicians to differentiate it from other diseases such as optic disc coloboma. CT and A/B-scan ultrasonography, in particular, are considered to be reliable imageological methods for the accurate diagnosis of MGS and are superior to the traditional techniques.

    Suboptimal asthma control is common despite modern asthma therapy. The degree of peripheral airway involvement remains unclear and poor medication delivery to these regions might be a contributing reason for this failure in obtaining adequate symptom control. A cohort of 196 adults (median (range) age 44 (18-61) years, 109 females, 54 ex-smokers, six current smokers) with physician-diagnosed asthma were recruited from primary care. Subjects were characterized clinically by interviews, questionnaires, skin prick tests (SPT) and blood eosinophil counts. Lung function was assessed by spirometry, impulse oscillometry (IOS) and nitrogen multiple breath washout (N2 MBW). IOS assessed peripheral airway resistance (FDR, frequency dependence of resistance). N2 MBW assessed global ventilation inhomogeneity (LCI, lung clearance index), specific indices of peripheral airway function (Scond × VT and Sacin × VT; VT, tidal volume), and inter-regional inhomogeneity (specific ventilation ratio). Never-smoking healthy cohorts of 158 and 400 adult subjects provided local reference values for IOS and N2 MBW variables, respectively. Peripheral airway dysfunction was detected in 31% (FDR or specific ventilation ratio) to 47% (Scond x VT) of subjects. Risk factors for peripheral airway dysfunction were identified. Among subjects with low FEV1 and either positive smoking history and/or blood eosinophilia (>4.0%), 63% had abnormality across all peripheral airway outcomes, whilst only one subject was completely normal. Abnormal peripheral airway function was present in a large proportion of adult asthmatics at baseline. Reduced FEV1, a positive smoking history, and/or blood eosinophilia identified "a small airway asthma subtype" that might benefit from peripheral airway targeted therapy. PMID:27492518

    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.

    Severe myoclonic epilepsy in infancy (SMEI) manifests very frequent generalized tonic-clonic seizures (GTC), accompanied by myoclonic seizures, absences and partial seizures [Dravet, C., 1978.

(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

    Abstract Alzheimer disease (AD) is the most frequent cause of dementia. AD diagnosis, progression, and treatment have not been analyzed nationwide in China. The primary aim of this study was to analyze demographic and clinical characteristics related to cognitive decline in AD patients treated at outpatient clinics in China. We performed a retrospective study of 1993 AD patients at 10 cognitive centers across 8 cities in China from March 2011 to October 2014. Of these, 891 patients were followed for more than 1 year. The mean age at diagnosis was 72.0 ± 10.0 years (range 38–96 years), and the mean age at onset of AD was 69.8 ± 9.5 years. Most patients (65.1%) had moderate to severe symptoms at the time of diagnosis, and mean Mini-Mental State Examination at diagnosis was 15.7 ± 7.7. AD patients showed significant cognitive decline at 12 months after diagnosis. Having more than 9 years of formal education was an independent risk factor related to rapid cognitive decline [odds ratio (OR) = 1.80; 95% confidence interval (95% CI): 1.11–2.91]. Early-onset AD patients experienced more rapid cognitive decline than late-onset patients (OR = 1.83; 95% CI: 1.09–3.06). Most AD patients in China had moderate to severe symptoms at the time of diagnosis and experienced significant cognitive decline within 1 year. Rapid cognitive decline in AD was related to having a higher educational level and younger age of onset. PMID:27367978

    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. PMID:27051493

    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.

    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.

    Linguistic characteristics of trauma narratives have been linked to the development and severity of posttraumatic stress disorder (PTSD). However, it remains unclear if linguistic markers of PTSD exist beyond the scope of trauma narratives. This study used ambiguous visual prompts to elicit spontaneous narratives from trauma-exposed individuals with (n = 23) and without PTSD (n = 30). Individuals with PTSD used more singular pronouns and death-related words, and fewer plural pronouns. Within the PTSD group, increased severity of reexperiencing symptoms was associated with greater use of singular pronouns and lower use of cognitive words; increased severity of avoidance symptoms was associated with lower use of death words; and increased severity of hyperarousal symptoms was associated with less frequent use of anxiety words. Together, these linguistic variables accounted for 53% of the variance in total PTSD symptom severity. These findings are consistent with previous research suggesting that language use is a strong predictor of PTSD psychopathology, and extend the evidence to include the linguistic characteristics of non-trauma-related narratives.

    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...

  20. An improved model of an actively contracting lymphatic vessel composed of several lymphangions: pumping characteristics

    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.

    1986-01-01

    Using the George Washington University biaxial test system, a static fracture toughness study of two polymers (PMMA and PVC) and three aluminum alloys was performed for several variations in specimen geometry. Photoelastic experiments indicate that the applied load biaxiality has a very strong influence on the size and shape of the crack-tip stress field, and fracture toughness values for both polymers were seen to decrease with increasing load biaxiality. The load biaxiality was also found to have a strong influence on the crack growth direction in PMMA and a negligible influence on the PVC. The 7075-T6 aluminum toughness values increased with biaxiality, while intermediate peak toughness values were noted at a 0.5 biaxiality ratio for the more ductile 2024-T3 and 6061-T4 alloys. Fracture toughnesses at the highest biaxiality ratios were found to be equal to the uniaxial results.

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.

    2016-01-01

    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.

    Full Text Available Fifteen apple cultivars grown in Valcea Research Station, Romania were evaluated in terms of fruit quality. Some selected compositional characteristics such as dry matter, total soluble solids, total sugar, titratable acidity, malic, citric and ascorbic acids and minerals content were investigated. Malic, citric and ascorbic acids were determined by a reversed-phase HPLC method. Sodium, calcium, magnesium, phosphorus, iron, manganese, copper, aluminium, chromium, zinc and strontium contents were determined by inductively coupled plasma-mass spectrometry following a microwave digestion while potassium content was determined by flame atomic absorption spectrometry. Large differences between cultivars were found for the contents of particular biochemical and mineral compounds. The dry matter content ranged between 12.49% (Prima and 20.09% (Red Boskoop while the total sugar content varied between 9.5% (Cadel and 15.03% (Red Boskoop. The highest titratable acidity was found in Red Boskoop (0.771%, while in Starkrimson the titratable acidity was only 0.101%. The respective ranges of malic and citric acid contents of the tested samples were: 522.2-1993.7 mg/100 g and 3.5-49.1 mg/100 g. The ascorbic acid content was on average 6.18 mg/100 g. Potassium was the most accumulated nutrient in fruits. The potassium content was comprised between 82.25 mg/100 g (Mutzu and 160.85 mg/100 g (Florina. Calcium follows, with variation limits between 1.70 mg/100 g (Starkrimson and 8.74 mg/100g (Prima while iron content varied between 0.19 mg/100 g (Ionagold and 0.40 mg/100 g (Cadel and Early Red. The observed differences in composition are of such magnitude that they may affect both nutritional and sensory properties.

    Traumatic brain injury (TBI) results in neurodegenerative changes that progress for months, perhaps even years post-injury. However, there is little information on the spatial distribution and the clinical significance of this late atrophy. In 24 patients who had sustained severe TBI we acquired ......, inferior and superior longitudinal fasciculus, corpus callosum and corona radiata. This indicates that the long-term atrophy is attributable to consequences of traumatic axonal injury. Despite progressive atrophy, remarkable clinical improvement occurred in most patients....

    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.

    Full Text Available BACKGROUND: Five pivotal clinical trials (Intensive Insulin Therapy; Recombinant Human Activated Protein C [rhAPC]; Low-Tidal Volume; Low-Dose Steroid; Early Goal-Directed Therapy [EGDT] demonstrated mortality reduction in patients with severe sepsis and expert guidelines have recommended them to clinical practice. Yet, the adoption of these therapies remains low among clinicians. OBJECTIVES: We selected these five trials and asked: Question 1--What is the current probability that the new therapy is not better than the standard of care in my patient with severe sepsis? Question 2--What is the current probability of reducing the relative risk of death (RRR of my patient with severe sepsis by meaningful clinical thresholds (RRR >15%; >20%; >25%? METHODS: Bayesian methodologies were applied to this study. Odds ratio (OR was considered for Question 1, and RRR was used for Question 2. We constructed prior distributions (enthusiastic; mild, moderate, and severe skeptic based on various effective sample sizes of other relevant clinical trials (unfavorable evidence. Posterior distributions were calculated by combining the prior distributions and the data from pivotal trials (favorable evidence. MAIN FINDINGS: Answer 1--The analysis based on mild skeptic prior shows beneficial results with the Intensive Insulin, rhAPC, and Low-Tidal Volume trials, but not with the Low-Dose Steroid and EGDT trials. All trials' results become unacceptable by the analyses using moderate or severe skeptic priors. Answer 2--If we aim for a RRR>15%, the mild skeptic analysis shows that the current probability of reducing death by this clinical threshold is 88% for the Intensive Insulin, 62-65% for the Low-Tidal Volume, rhAPC, EGDT trials, and 17% for the Low-Dose Steroid trial. The moderate and severe skeptic analyses show no clinically meaningful reduction in the risk of death for all trials. If we aim for a RRR >20% or >25%, all probabilities of benefits become lower

    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

    In this study, the precipitation over the Loess Tableland in Changwu County of Shaanxi Province and the soil water in 0-20 m loess profiles under different land use patterns on the Tableland were sampled, and their isotope compositions were analyzed, aimed to understand the characteristics of stable isotopes in the soil water and the mechanisms of the soil water movement. In the study area, the equation of the local meteoric water line (LMWL) was deltaD = 7.39 delta180 + 4.34 (R2 = 0.94, n = 71), and the contents of the stable isotopes in the precipitation had an obvious seasonal variation of high in winter and spring and low in summer and autumn. The contents of the stable isotopes in the soil water were fell on the underside of the LMWL, and higher than those in the precipitation from July to October, indicating that the soil water was mainly replenished by the precipitation with lower stable isotope contents in summer and autumn. In the soil profiles of different land use patterns, the stable isotope contents in soil water tended to be the same with the increasing soil depth; while under the same land use patterns, the water's stable isotope composition in shallow soil layers changed greatly with time, but changed less with increasing depth. Through the comparison of the stable isotope contents in precipitation and in soil water, it was observed that the piston flow and preferential flow on the Tableland were coexisted in the process of precipitation infiltration, and the occurrence of the preferential flow had a certain relation with land use pattern. Generally, the soil desiccation caused by the negative water balance resulted from the artificial plantations of high water consumption could reduce the probability of preferential flow occurrence, whereas the precipitation infiltration in the form of preferential flow could easily occur on the farmland or natural grassland so that the soil water in deep layers or the ground water could be replenished.

    We prospectively quantified disease severity associated with epidemiologic and socioeconomic parameters as well as the clinical factors in 195 previously healthy infants with confirmed respiratory syncytial virus (RSV) infection. Infants were enrolled into three subgroups according to disease severity: outpatients (82 patients), inpatients (100 patients), and intensive care unit patients (13 patients). Epidemiologic parameters such as gestational age, birth weight, chronologic age at presentation, and gender as well as socioeconomic factors such as ethnic origin, family history of asthma, exposure to cigarette smoke, number of family members, presence of pets at home, breast-feeding, and day-care attendance were not found to predict the severity of RSV illness in previously healthy infants. Our results emphasize the complexity of predicting disease severity in previously healthy infants with RSV infection and suggest that other parameters such as host genetic background might explain the clinical variability.

    Full Text Available Question: What are the experiences of students and clinical educators in a paired student placement model incorporating facilitated peer-assisted learning (PAL activities, compared to a traditional paired teaching approach? Design: Qualitative study utilising focus groups. Participants: Twenty-four physiotherapy students and 12 clinical educators. Intervention: Participants in this study had experienced two models of physiotherapy clinical undergraduate education: a traditional paired model (usual clinical supervision and learning activities led by clinical educators supervising pairs of students and a PAL model (a standardised series of learning activities undertaken by student pairs and clinical educators to facilitate peer interaction using guided strategies. Results: Peer-assisted learning appears to reduce the students’ anxiety, enhance their sense of safety in the learning environment, reduce educator burden, maximise the use of downtime, and build professional skills including collaboration and feedback. While PAL adds to the clinical learning experience, it is not considered to be a substitute for observation of the clinical educator, expert feedback and guidance, or hands-on immersive learning activities. Cohesion of the student-student relationship was seen as an enabler of successful PAL. Conclusion: Students and educators perceive that PAL can help to position students as active learners through reduced dependence on the clinical educator, heightened roles in observing practice, and making and communicating evaluative judgments about quality of practice. The role of the clinical educator is not diminished with PAL, but rather is central in designing flexible and meaningful peer-based experiences and in balancing PAL with independent learning opportunities.

    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.

    Full Text Available Aluminium phosphide poisoning is very common in India. It is one of the most fatal poisons. The clinical spectrum of poisoning varies depending upon the dosage and duration of consumption. The main effect of the poison is due to the release of phosphine which inhibits cytochrome oxidase and thereby hampers cellular oxygen utilization. Almost any organ can be affected by aluminium phosphide poisoning. We report a case where the heart was the predominantly affected organ. We describe the clinical symptoms and signs and their correlation with electrocardiographic and histopathological examinations.

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.

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.

    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.

    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.

    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.

  2. Ascitic microbiota composition is correlated with clinical severity in cirrhosis with portal hypertension.

    Directory of Open Access Journals (Sweden)

    Geraint B Rogers

    Full Text Available Identification of pathogenic bacteria in ascites correlates with poor clinical outcomes. Ascites samples are commonly reported culture-negative, even where frank infection is indicated. Culture-independent methods have previously reported bacterial DNA in ascites, however, whether this represents viable bacterial populations has not been determined. We report the first application of 16S rRNA gene pyrosequencing and quantitative PCR in conjunction with propidium monoazide sample treatment to characterise the viable bacterial composition of ascites. Twenty five cirrhotic patients undergoing paracentesis provided ascites. Samples were treated with propidium monoazide to exclude non-viable bacterial DNA. Total bacterial load was quantified by 16S rRNA Q-PCR with species identity and relative abundance determined by 16S rRNA gene pyrosequencing. Correlation of molecular microbiology data with clinical measures and diagnostic microbiology was performed. Viable bacterial signal was obtained in 84% of ascites samples, both by Q-PCR and pyrosequencing. Approximately 190,000 ribosomal pyrosequences were obtained, representing 236 species, including both gut and non gut-associated species. Substantial variation in the species detected was observed between patients. Statistically significant relationships were identified between the bacterial community similarity and clinical measures, including ascitic polymorphonuclear leukocyte count and Child-Pugh class. Viable bacteria are present in the ascites of a majority of patients with cirrhosis including those with no clinical signs of infection. Microbiota composition significantly correlates with clinical measures. Entry of bacteria into ascites is unlikely to be limited to translocation from the gut, raising fundamental questions about the processes that underlie the development of spontaneous bacterial peritonitis.

    Importance Though cerebral amyloid angiopathy (CAA) has important clinical implications, our understanding of it and ability to diagnose it is limited. Objective We sought to determine pathological correlates and clinical factors identifiable during life that predict the presence of severe CAA in persons with pathologically-confirmed Alzheimer’s disease (AD). Design We compared demographic and clinical variables at the earliest visit during life at which subjects were found to have cognitive impairment, and pathological variables between persons ultimately found to have no or severe CAA at autopsy using logistic regression. Analyses were repeated separately for carriers and non-carriers of the APOE ε4 allele. Setting Data were obtained from the Uniform Data Set that comprises longitudinal clinical assessments performed in the Alzheimer’s Disease Centers funded by the National Institute on Aging. Participants 193 persons with severe CAA and 232 persons with no CAA. All subjects had cognitive impairment and met NIA-Reagan neuropathological criteria for AD. Main Outcome Measures Prevalence of demographic characteristics and the APOE ε4 allele and odds ratios of clinical variables for the prediction of severe CAA. Results Persons with severe CAA were more likely to carry an APOE ε4 allele (64.9% vs. 42.8%), to be Hispanic (6.8% vs. 1.3%, p = 0.003), to have had a transient ischemic attack (TIA, 12.5% vs. 6.1%, OR = 2.1, 95% CI = 1 – 4.4), and had lower degrees of diffuse amyloid plaque pathology (mean CERAD scores 1.2 vs. 1.4, p = 0.01) than persons with no CAA. Intracerebral hemorrhage (9.3% vs. 3.5%, p = 0.01), cortical microinfarcts (20.7% vs. 12.9%, p = 0.03), and subcortical leukoencephalopathy (20.5% vs. 12.1%, p = 0.02) were more common in persons with CAA. A higher prevalence of stroke (11.1% vs. 3.9%, OR = 3.8, 95% CI 1.0 – 14.6) and hypercholesterolemia (50% vs. 33.3%, OR = 2.3, CI 1.1 – 4.7) were found in non-carriers of the ε4 allele with

    2006-01-01

    Full Text Available The severity of cystic fibrosis (CF pulmonary disease is not directly related to CFTR genotype but depends upon several parameters, including neutrophil-dominated inflammation. Identification of agents modulating inflammation constitutes a relevant goal. Myeloperoxidase (MPO is involved in both microbicidal and proinflammatory neutrophil activities. The aim of this study was to evaluate whether the −463GA MPO promoter polymorphism is linked to clinical severity of CF-associated pulmonary inflammation. This polymorphism significantly affects the level of MPO gene expression in leukocytes and the G allele is more expressing than the A allele. We show that MPO genotype significantly influences the severity of pulmonary disease in early stages, prior to the development of chronic lung infections, with GG genotype being associated with more severe CF disease. Our findings indicate that the level of MPO gene expression influences the CF pathogenesis, presumably reflecting cellular damage by MPO-generated oxidants or other activity of MPO in airway inflammation.

    Background WHO’s new classification in 2009: dengue with or without warning signs and severe dengue, has necessitated large numbers of admissions to hospitals of dengue patients which in turn has been imposing a huge economical and physical burden on many hospitals around the globe, particularly South East Asia and Malaysia where the disease has seen a rapid surge in numbers in recent years. Lack of a simple tool to differentiate mild from life threatening infection has led to unnecessary hospitalization of dengue patients. Methods We conducted a single-centre, retrospective study involving serologically confirmed dengue fever patients, admitted in a single ward, in Hospital Kuala Lumpur, Malaysia. Data was collected for 4 months from February to May 2014. Socio demography, co-morbidity, days of illness before admission, symptoms, warning signs, vital signs and laboratory result were all recorded. Descriptive statistics was tabulated and simple and multiple logistic regression analysis was done to determine significant risk factors associated with severe dengue. Results 657 patients with confirmed dengue were analysed, of which 59 (9.0%) had severe dengue. Overall, the commonest warning sign were vomiting (36.1%) and abdominal pain (32.1%). Previous co-morbid, vomiting, diarrhoea, pleural effusion, low systolic blood pressure, high haematocrit, low albumin and high urea were found as significant risk factors for severe dengue using simple logistic regression. However the significant risk factors for severe dengue with multiple logistic regressions were only vomiting, pleural effusion, and low systolic blood pressure. Using those 3 risk factors, we plotted an algorithm for predicting severe dengue. When compared to the classification of severe dengue based on the WHO criteria, the decision tree algorithm had a sensitivity of 0.81, specificity of 0.54, positive predictive value of 0.16 and negative predictive of 0.96. Conclusion The decision tree algorithm proposed

    Telomere shortening occurs with human aging in many organs and tissues and is accelerated by rapid cell turnover and oxidative injury. To clarify the clinical importance of telomere shortening in colonic mucosa in ulcerative colitis (UC), we measured average telomere length using quantitative real-time PCR in non-neoplastic colonic mucosa in UC patients and assessed its relationship to various clinical subtypes. Relative telomere length in genomic DNA was measured in colonic biopsies obtained from rectal inflammatory mucosa from 86 UC patients as well as paired non-inflammatory proximal colonic mucosae from 10 patients. Data were correlated with various clinical phenotypes. In paired samples, average relative telomere length of rectal inflammatory mucosa was shortened compared to normal appearing proximal colon in eight out of ten cases (p = 0.01). Telomere length shortening was significantly associated with more severe Mayo endoscopic subscore (p telomere length was significantly shortened in the same phenotypes than the others (p = 0.003). Telomere shortening is associated with more severe clinical phenotypes of UC, reflecting severe inflammatory state in the colonic mucosa.

    Full Text Available Background and Objectives: Neuroimaging studies have found higher rates of white matter hyperintensities (WMHs in patients with bipolar disorder (BD of all ages, although whether BD is associated with increased rates of WMHs independently from age and cerebrovascular risk factors is still matter of debate. The outcome of BD associated with severe WMHs is generally poor, but several authors have suggested that some factors could have a protective role in BD. The aim of the present study was to report the two-year follow-up of a woman with BD type I and severe WMH/PWMH lesions who was taking high concentrations of vitamin-D in her nutrition, as well as taking lithium and haloperidol as treatment. Case presentation: A 76-year-old woman was hospitalized for a mixed state BD. She had severe WMHs. She took lithium and haloperidol during the hospitalization and was euthymic at discharge as well as after two-years of follow-up. Her nutrition had a high concentration of Vitamin-D. Unfortunately, it was not possible to give her a second MRI. Conclusions: Although there was probable persistence of WMHs, the patient improved in both mood and quality of life. The possible protective effect of lithium and Vitamin-D is discussed.

    Kenny Caffey syndrome (KCS) is a rare syndrome reported almost exclusively in Middle Eastern populations. It is characterized by severe growth retardation-short stature, dysmorphic features, episodic hypocalcaemia, hypoparathyroidism, seizures, and medullary stenosis of long bones with thickened cortices. We report a 10-year-old boy with KCS with an unusually severe respiratory and gastrointestinal system involvement-features not previously described in the literature. He had severe psychomotor retardation and regressed developmentally from walking unaided to sitting with support. MRI brain showed bilateral hippocampal sclerosis, marked supra-tentorial volume loss and numerous calcifications. A 12 bp deletion of exon 2 of tubulin-specific chaperone E (TBCE) gene was identified and the diagnosis of KCS was confirmed. Hypercarbia following a sleep study warranted nocturnal continuous positive airway pressure (CPAP) when aged 6. When boy aged 8, persistent hypercarbia with increasing oxygen requirement and increased frequency and severity of lower respiratory tract infections led to progressive respiratory failure. He became fully dependent on non-invasive ventilation and by 9 years he had a tracheotomy and was established on long-term ventilation. He developed retching, vomiting and diarrhea. Chest CT showed changes consistent with chronic aspiration, but no interstitial pulmonary fibrosis. He died aged 10 from respiratory complications. PMID:26029652

    Ischemic vascular disease of the upper extremity represents a difficult therapeutic problem wherein medical treatment often fails. Epidural spinal cord stimulation has been shown to be an effective alternative in severe peripheral arterial disease. Although this method has been used for nearly two decades only limited experience exists in Raynaud's phenomenon of the upper limbs. In addition objective parameters to prove therapeutic success are not well defined. Herein we describe a patient with severe primary Raynaud's phenomenon over several years who had significant pain relief and complete healing of ischemic digital ulcerations after spinal cord stimulation. Pain level was evaluated using a visual rating scale before and after surgery. Microcirculatory parameters were assessed before and after spinal cord stimulation by capillary microscopy and laser Doppler anemometry. Significant improvement of red blood cell velocity, capillary density, and capillary permeability was demonstrated. At follow-up 18 months after surgery the patient had no complaints and all ulcerations of her fingertips had healed. Spinal cord stimulation appears to be an effective treatment in severe cases of Raynaud's phenomenon and we recommend its use in the case of failed medical therapy. Pain rating and capillary microscopy enable one to assess and visualize the effects of spinal cord stimulation.

    To investigate the difference of biochemical characteristics on gsp-positive and gsp-negative growth hormone (GH)-secreting pituitary tumors, 18 GH-secreting pituitary tumors were examined for their clinical characteristics and gsp oncogenes. All patients received the pituitary function combinative stimulating test. It was found that there were no difference in the sex, age, tumor size, course of disease and plasma basal GH levels with gsp- positive and gsp-negative patients. The plasma levels of PRL were increased in most patients (11/18), and the plasma levels of TSH in gsp-positive patients were higher than those in gsp-negative patients (P<0.05). There was no significant difference in the responses to pituitary combinative stimulating test in gsp-positive and gsp-negative patients. It was concluded that there was little difference in the clinical biochemical characteristics of gsp-positive with gsp-negative GH-secreting pituitary tumors.

    2010-12-01

    Full Text Available Restless legs syndrome (RLS is a neurological disorder that responds to dopaminergic drugs, indicating a common pathophysiology with Parkinson's disease (PD. The prevalence of RLS was estimated in a group of PD patients and its clinical and biochemical characteristics were analysed. Forty-eight patients with PD were evaluated into two groups, with and without RLS. Clinical characteristics assessed in both groups were age, gender, duration of PD, Hoehn and Yahr, and Schwab and England scales. Laboratory variables such as hemoglobin, s-iron, s-ferritin and creatinine were obtained. The prevalence of RLS was 18.75%. No significant differences regarding clinical variables and biochemical parameters were observed. The high prevalence of RLS found in PD patients suggests the concept of a common etiological link and it seems that secondary causes did not play a central role in the pathophysiology of RLS in this group of parkinsonian patients.

    1998-01-01

    Fifty nine asthmatic children and adolescents, clinically stable, aged 6 to 15 years, 37 boys and 22 girls, from Instituto da Criança do Hospital das Clínicas da FMUSP, were studied from September to November, 1994. The patients were classified by the clinical score of the International Consensus for Asthma Diagnosis and Management. They performed baseline spirometry and peak expiratory flow rates (PEFR), before and after bronchodilator, and measured PEFR three times a day (6 pm, at bedtime and on waking), for one day, at home. Five PEF measurements were made serially and the best readings were considered. Variability of PFE was calculated for 24 hours, as assessed by maximal amplitude. The results were summited to statistical analysis of the Laboratorio de Informática Médica da Faculdade de Medicina da USP. The results of PEFR and it's variability were compared to spirometry, (functional score, FEV1-forced expiratory volume in the first second) and to the clinical score of the International Consensus for Asthma Diagnosis and Management. In case of disagreement between the clinical parameters, the more severe one was chosen. The clinical score classified 20.3% of our patients as mild obstruction, 49.2% as moderate and 30.5% as severely compromised. According to FEV1, 58% of patients were classified as normal while the PEFR and its variability classified as normal 76% and 71%. The PEFR and it's variability in 24 hours, correlated with the VEF1, as gold standard, showed good specificity, 91% and 76% respectively and low sensibility, 44% and 32%. It was detected a low level of agreement between FEV1, PEFR and it's variability in 24 hours, in the clinical severity classification of asthma. The results of this study showed that FEV1 and PEFR had a low level of agreement in the clinical severity classification of asthma and when they were correlated to the clinical score of the International Consensus, they both presented low sensitivity.

However, different areas of medical research may have considerably different citation practices, even within the same medical field. Because of this, it is unclear to what extent citation-based bibliometric indicators allow for valid comparisons between research units active in different areas of medical research. Methodology A visualization methodology is introduced that reveals differences in citation practices between medical research areas. The methodology extracts terms from the titles and abstracts of a large collection of publications and uses these terms to visualize the structure of a medical field and to indicate how research areas within this field differ from each other in their average citation impact. Results Visualizations are provided for 32 medical fields, defined based on journal subject categories in the Web of Science database. The analysis focuses on three fields: Cardiac & cardiovascular systems, Clinical neurology, and Surgery. In each of these fields, there turn out to be large differences in citation practices between research areas. Low-impact research areas tend to focus on clinical intervention research, while high-impact research areas are often more oriented on basic and diagnostic research. Conclusions Popular bibliometric indicators, such as the h-index and the impact factor, do not correct for differences in citation practices between medical fields. These indicators therefore cannot be used to make accurate between-field comparisons. More sophisticated bibliometric indicators do correct for field differences but still fail to take into account within-field heterogeneity in citation practices.

    Full Text Available Results from cohort studies evaluating the severity of respiratory viral co-infections are conflicting. We conducted a systematic review and meta-analysis to assess the clinical severity of viral co-infections as compared to single viral respiratory infections.We searched electronic databases and other sources for studies published up to January 28, 2013. We included observational studies on inpatients with respiratory illnesses comparing the clinical severity of viral co-infections to single viral infections as detected by molecular assays. The primary outcome reflecting clinical disease severity was length of hospital stay (LOS. A random-effects model was used to conduct the meta-analyses.Twenty-one studies involving 4,280 patients were included. The overall quality of evidence applying the GRADE approach ranged from moderate for oxygen requirements to low for all other outcomes. No significant differences in length of hospital stay (LOS (mean difference (MD -0.20 days, 95% CI -0.94, 0.53, p = 0.59, or mortality (RR 2.44, 95% CI 0.86, 6.91, p = 0.09 were documented in subjects with viral co-infections compared to those with a single viral infection.

    Neonatal primary hyperparathyroidism is a rare entity characterized by marked hypercalcemia, diffuse parathyroid hyperplasia, and skeletal demineralization. It is often lethal unless total parathyroidectomy is performed. Long-term outcome of treated patients is poorly documented. We report the clinical and radiographic outcome of this disease in a 7-year-old boy who underwent a total parathyroidectomy and autotransplantation of a fragment of one parathyroid gland to his thigh in the neonatal period. This paper demonstrates the importance of prompt diagnosis and management in neonatal hyperparathyroidism and the role of various imaging modalities in its diagnosis and follow-up. (orig.)

  2. Clinical value of radiological methods in evaluation and therapy of severe thoracic trauma

    International Nuclear Information System (INIS)

    Plain chest radiographs allow the diagnosis of most intrathoracic injuries. However, they are only momentary pictures and give no information on the respiratory function. A tension pneumothorax, rib fractures and subcutaneous emphysema should be diagnosed clinically before radiographs are taken. Computed tomography is helpful in evaluation of intrapulmonary lesions, hemothorax, rupture of the diaphragm and dislocation of the heart. Further diagnostic tools include aortography in suspected aortic rupture, sonography in cardiac injuries and hemopericardium, bronchoscopy in suspected bronchial or tracheal rupture, ECG and enzyme determinations in cardiac contusion, and eventually pneumoperitoneum in suspected rupture of the diaphragm.

    The aim of this study was to evaluate the association between various functional and occlusal parameters and sleep bruxism. Thirty-nine (39) sleep bruxism patients and 30 controls participated in this investigation. The assessment of sleep bruxism was performed using the Bruxcore Bruxism-Monitoring Device (BBMD) combined with a new computer-based analyzing method. Sixteen functional and/or occlusal parameters were recorded. With a mean slide of 0.95 mm in the sleep bruxism group and a mean slide of 0.42 mm in the control group (Mann Whitney U test; p<0.003), results solely demonstrated a significant group difference regarding the length of a slide from centric occlusion to maximum intercuspation. The results suggest that the slightly pronounced slide could be of clinical importance in the development of increased wear facets in patients with current sleep bruxism activity. Following further evaluation including polysomnographic recordings, the BBMD combined with this new analyzing technique seems to be a clinically feasible instrument that allows the practitioner to quantify abrasion over a short period.

    We evaluated the frequency and subtypes of clinically relevant cardiovascular (CV) findings identified on staging computed tomography (CT) in a large sample. Patients (n = 5026) with different malignant diseases were staged by CT. Clinically relevant CV findings (CRCFs) were included into the study. The CRCFs were defined as cardiac aneurysm, cardiac thrombus, venous thrombosis, arterial thrombosis, arterial dissection, pulmonary thromboembolism, arterial dissection, and dislocation of venous ports/central venous catheters. The CRCFs were identified in 342 patients (6.8% of all patients). Overall, 491 CRCFs were identified in the patients (1.4 per patient). In 203 (59.4%) patients, 1 CRCF; in 129, 2 (37.7%) CRCFs; and in 10 (2.9%) cases, 3 CRCFs were detected. There were incidental venous thrombosis (n = 298, 60.7% of all CRCFs), pulmonary thromboembolism (n = 84, 17.1%), arterial aneurysms (n = 44, 8.9%), arterial thrombosis (n = 43, 8.8%), heart thrombus (n = 15, 3.1%), arterial dissection (n = 3, 0.6%), heart aneurysms (n = 2, 0.4%), and port catheter dislocation (n = 2, 0.4%). The identified CRCF can be associated with potential hazardous complications. The CV system should be carefully evaluated in staging CT investigations. PMID:26399716

    Full Text Available Abstract Background Hypoglycaemia is a poor prognostic indicator in severe malaria. Intravenous infusions are rarely feasible in rural areas. The efficacy of sublingual sugar (SLS was assessed in a pilot randomized controlled trial among hypoglycaemic children with severe malaria in Mali. Methods Of 151 patients with presumed severe malaria, 23 children with blood glucose concentrations = 3.3 mmol/l (60 mg/dl within 40 minutes after admission. Secondary outcome measures were early treatment response at 20 minutes, relapse (early and late, maximal BGC gain (CGmax, and treatment delay. Results There was no significant difference between the groups in the primary outcome measure. Treatment response occurred in 71% and 67% for SLS and IVG, respectively. Among the responders, relapses occurred in 30% on SLS at 40 minutes and in 17% on IVG at 20 minutes. There was one fatality in each group. Treatment failures in the SLS group were related to children with clenched teeth or swallowing the sugar, whereas in the IVG group, they were due to unavoidable delays in beginning an infusion (median time 17.5 min (range 3–40. Among SLS, the BGC increase was rapid among the nine patients who really kept the sugar sublingually. All but one increased their BGC by 10 minutes with a mean gain of 44 mg/dl (95%CI: 20.5–63.4. Conclusion Sublingual sugar appears to be a child-friendly, well-tolerated and effective promising method of raising blood glucose in severely ill children. More frequent repeated doses are needed to prevent relapse. Children should be monitored for early swallowing which leads to delayed absorption, and in this case another dose of sugar should be given. Sublingual sugar could be proposed as an immediate "first aid" measure while awaiting intravenous glucose. In many cases it may avert the need for intravenous glucose.

    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 pred...

    @@ Dental abnormalities associated with specific syndromes and/or severe systemic abnormalities in tooth number, form or size are challenging cases in dentistry, affecting esthetics and function.1 Microdontia is used to term abnormally small teeth that generally the maxillary lateral incisor or third molar is involved. On the other hand, the entire dentition may be affected as well.1 Prevalence of microdontia range from 1.5%-2%.2 The definition of severe hypodontia is four or more lacking teeth.3-5 The prevalence of severe hypodontia was found to be less than 1% of the unselected population.6 In another study hypo-dontia is seen with a higher incidence in the permanent dentition (3.5%-6.5%), compared to that of the primary one (0.1%-0.9%).7 The etiology seems to be inheritance in most cases of hypodontia. However, some are caused by mechanical trauma to jaws during tooth formation, by infection or by the effects of cytostatica and radiation during cancer treatment.6 There are more than 160 syndromes combined with hypo-dontia.6 Some of them are ectodermal dysplasia, Rieger syndrome and incontinentia pigmenti. In such cases morphological aberrancies as microdontia and conical crowns may be additional features.6 In addition to the number of lacking teeth, tooth eruption, occlusion and craniofacial parameters are influenced.

  11. Clinical significance of I-123 MIBG myocardial scintigraphy for evaluating the severity of congestive heart failure

    International Nuclear Information System (INIS)

    We studied the significance of I-123 MIBG (metaiodobenzylguanidine) myocardial scintigraphy for evaluating the severity of congestive heart failure (CHF). I-123 MIBG scintigraphy was performed in 7 patients with CHF of NYHA class I-III (6 with dilated cardiomyopathy and 1 with adriamycine cardiomyopathy) and in 2 normals. The SPECT and anterior planar myocardial images were obtained 15 minutes after (initial images) and 4 hours after (delayed images) an injection of I-123 MIBG (111 MBq). Compared with normals, patients with CHF demonstrated (1) low myocardial uptake and (2) rapid myocardial washout of I-123 MIBG, indicating myocardial sympathetic disarrangement. Then, quantitating these abnormalities with the heart to upper mediastinum uptake ratio (H/B) and the percent washout rate (%WR) during 4 hours, respectively, we compared these two indices with LV ejection fraction (EF) at rest measured by echocardiography and exercise capacity (max VO2 and VO2 at anaerobic threshold (AT)) determined with respiratory gas exchange analysis during maximal bicycle exercise. H/B was lower and %WR was greater in patients with CHF than in normals. H/B correlated with EF (r=0.77, p2 (r=-0.74, p<0.05) and AT (r=-0.81, p<0.05). Thus, H/B and %WR were closely related to the severity of CHF. These results suggest that I-123 MIBG myocardial scintigraphy and the quantitative analysis of I-123 MIBG myocardial uptake provide useful information about the severity of CHF. (author)

    Full Text Available Objective: To investigate the application of percutaneous endoscopic gastrostomy (PEG to patients with severe craniocerebral injury for the purpose of nutritional support therapy and pulmonary infection prevention. Methods: A total of 43 patients with severe craniocerebral injury admitted to our department from January 2008 to December 2012 received PEG followed by nutritional therapy. There were other 82 patients who were prescribed nasal-feeding nutrition. Nutrition status was evaluated by comparing serum albumin levels, and the incidence of pulmonary infection 1 week before and 2 weeks after operation was identifi ed and compared. Results: Both PEG and nasal-feeding nutrition therapies have significantly levated serum albumin levels (P<0.05. Serum albumin levels before and after nutritional therapies showed no significant difference between the two groups (P>0.05. The incidence of pulmonary infection in PEG group was significantly decreased compared with that in nasal-feeding nutrition group (P<0.05. Conclusion: PEG is an effective method for severe craniocerebral injury patients. It can not only provide enteral nutrition but also prevent pulmonary infection induced by esophageal refl ux.

    Full Text Available BACKGROUND: Rotavirus, predominantly of group A, is a major cause of severe diarrhoea worldwide, with the greatest burden falling on young children living in less-developed countries. Vaccines directed against this virus have shown promise in recent trials, and are undergoing effectiveness evaluation in sub-Saharan Africa. In this region limited childhood data are available on the incidence and clinical characteristics of severe group A rotavirus disease. Advocacy for vaccine intervention and interpretation of effectiveness following implementation will benefit from accurate base-line estimates of the incidence and severity of rotavirus paediatric admissions in relevant populations. The study objective was to accurately define the incidence and severity of group A rotavirus disease in a resource-poor setting necessary to make informed decisions on the need for vaccine prevention. METHODS AND FINDINGS: Between 2002 and 2004 we conducted prospective surveillance for group A rotavirus infection at Kilifi District Hospital in coastal Kenya. Children 2% of children are admitted to hospital with group A rotavirus diarrhoea in the first 5 y of life. This translates into over 28,000 vaccine-preventable hospitalisations per year across Kenya, and is likely to be a considerable underestimate. Group A rotavirus diarrhoea is associated with acute life-threatening metabolic derangement in otherwise healthy children. Although mortality is low in this clinical research setting this may not be generally true in African hospitals lacking rapid and appropriate management.

    The current authors introduced an innovative autovideography intervention asking mental health consumers to use video cameras for 1 month to tell about their recovery. The research approach was based on a participatory research model with workers and consumers of a recovery education center fully involved with the study design and implementation. Twelve individuals who had graduated from a recovery program participated. The participant-produced videos were qualitatively analyzed using thematic analysis. The use of autovideography was found to be feasible and can be used clinically to support the process of recovery by providing opportunities for reciprocity, self-reflection, and advocacy. Consumer-produced videos provide a voice to inform others with and without mental illness about the concerns of individuals with mental illness and the process of recovery.

    Hidradenitis suppurativa is a chronic inflammatory disorder that has attracted increasing attention in recent years due to underestimations of prevalence and the considerable impact of the condition on interpersonal relationships, physical appearance, self-esteem, and body image. Although hidradenitis suppurative has a significant psychological impact on patients and can even cause physical limitations when thick scarring results in limb mobility limitation, until very recently little evidence was available relating to its epidemiology, etiology, or pathogenesis. In this review, we highlight the latest advances in our understanding of the epidemiological and clinical aspects of hidradenitis suppurativa. We will also look at the different classification systems for hidradenitis suppurativa and discuss the emergence of skin ultrasound as a promising technique for monitoring the course of this chronic inflammatory disease.

    Candida spp. are often the cause of infection in immune-compromised individuals. They are characterized by a strong resistance to antimicrobial drugs and disinfectants. The activity of Artemisia annua essential oil against Candida spp. was determined by vapour contact and microdilution assay. The oil was characterized by the presence of oxygenated monoterpenes (more than 75 % of the constituents), mainly represented by the irregular monoterpene artemisia ketone (ca. 22 %), and the widespread monoterpenes 1,8 cineole (ca. 19 %) and camphor (ca. 17 %). Other representative constituents were artemisia alcohol (5.9 %), α-pinene (5.7 %), and pinocarvone (3.0 %). Thujone, a typical toxic constituent of the Artemisia species, was not detected. The results are reported as minimum inhibitory concentration, minimum fungicidal concentration, and diameter of inhibition zone obtained by the vapour diffusion assay. We tested 10 clinical Candida strains, coming from both clinical samples and international collections. The results show that the antifungal activity of A. annua is influenced by the type of method adopted. The inhibitory action of the essential oil was, in fact, higher in the vapour than in the liquid phase. Our results show an average minimum inhibitory concentration in the liquid phase of 11.88 µL/mL, while in the vapour phase, the growth of all Candida strains tested at a concentration of 2.13 µL/cm(3) was inhibited. A strain of Candida glabrata was found to be less susceptible to the liquid medium than the vapour assay (50 µL/mL vs. 0.64 µL/cm(3), respectively). Candida albicans and Candida dubliniensis were the most susceptible to the vapour test, while Candida parapsilosis was the most resistant. PMID:27286334

    Full Text Available Abstract Background Application of plane geometry to the study of bunion deformity may represent an interesting and novel approach in the research field of hallux valgus. For the purpose of contributing to development of a different perspective in the assessment of hallux valgus, this study was conducted with three objectives: a to determine the position on the intersection point of the perpendicular bisectors of the longitudinal axes of the first metatarsal and proximal phalanx (IP, b to correlate the location of this point with hallux valgus deformity according to angular measurements and according to visual assessment of the severity carried out by three independent observers, and c to assess whether this IP correlated with the radius of the first metatarsophalangeal arc circumference. Methods Measurements evaluated were intermetatarsal angle (IMA, hallux valgus angle (HVA, and proximal phalangeal articular angle (PPAA. The Autocad® program computed the location of the IP inside or outside of the foot. Three independent observers rated the severity of hallux valgus in photographs using a 100-mm visual analogue scale (VAS. Results Measurements of all angles except PPAA showed significantly lower values when the IP was located out of the foot more distantly and vice versa, significantly higher values for severe deformities in which the IP was found inside the foot (p p Conclusion The IP is a useful indicator of hallux valgus deformity because correlated significantly with IMA and HVA measurements, VAS scores obtained by visual inspection of the degree of deformity, and location of the center of the first metatarsophalangeal arc circumference.
