We aimed to evaluate sociodemographic, epidemiological, and clinical risk factors for pulmonary tuberculosis (PTB) in children presenting with severe acute malnutrition (SAM) and pneumonia. Children aged 0 to 59 months with SAM and radiologic pneumonia from April 2011 to July 2012 were studied in Bangladesh. Children with confirmed PTB (by culture and/or X-pert MTB/RIF) (cases = 27) and without PTB (controls = 81; randomly selected from 378 children) were compared. The cases more often had the history of contact with active PTB patient (P < .01) and exposure to cigarette smoke (P = .04) compared with the controls. In logistic regression analysis, after adjusting for potential confounders, the cases were independently associated with working mother (P = .05) and positive tuberculin skin test (TST; P = .02). Thus, pneumonia in SAM children is a common presentation of PTB and further highlights the importance of the use of simple TST and/or history of contact with active TB patients in diagnosing PTB in such children, especially in resource-limited settings.

Cranial dural arteriovenous fistulae have been classified into high- and low-risk lesions mainly based on the pattern of venous drainage. Those with leptomeningeal venous drainage carry a higher risk of an aggressive clinical presentation. Recently, it has been proposed that the clinical presentation should be considered as an additional independent factor determining the clinical course of these lesions. However, dural shunts with leptomeningeal venous drainage include a very wide spectrum of inhomogeneous lesions. In the current study, we correlated the clinical presentation of 107 consecutive patients harboring cranial dural arteriovenous shunts with leptomeningeal venous drainage, with their distinct anatomic and angiographic features categorized into eight groups based on the "DES" (Directness and Exclusivity of leptomeningeal venous drainage and features of venous Strain) concept. We found that among these groups, there are significant angioarchitectural differences, which are reflected by considerable differences in clinical presentation. Leptomeningeal venous drainage of dural sinus shunts that is neither direct nor exclusive and without venous strain manifested only benign symptoms (aggressive presentation 0%). On the other end of the spectrum, the bridging vein shunts with direct and exclusive leptomeningeal venous drainage and venous strain are expected to present aggressive symptoms almost always and most likely with bleeding (aggressive presentation 91.5%). Important aspects of the above correlations are discussed. Therefore, the consideration of leptomeningeal venous drainage alone, for prediction of the clinical presentation of these shunts appears insufficient. Angiographic analysis based on the above concept, offers the possibility to distinguish the higher- from the lower-risk types of leptomeningeal venous drainage. In this context, consideration of the clinical presentation as an additional independent factor for the prediction of their clinical

Invasive fungal diseases (IFDs) are devastating opportunistic infections that result in significant morbidity and death in a broad range of pediatric patients, particularly those with a compromised immune system. Recognizing them can be difficult, because nonspecific clinical signs and symptoms or isolated fever are frequently the only presenting features. Therefore, a high index of clinical suspicion is necessary in patients at increased risk of IFD, which requires knowledge of the pediatric patient population at risk, additional predisposing factors within this population, and the clinical signs and symptoms of IFD. With this review, we aim to summarize current knowledge regarding the recognition and clinical presentation of IFD in neonates and children. © The Author 2017.

To identify clinical factors associated with a change from vertex to nonvertex presentation in the second twin after vaginal birth of the first. We assembled a retrospective cohort of women with viable vertex-vertex twin pregnancies who delivered the presenting twin vaginally. Women whose second twin changed from vertex to nonvertex after vaginal birth of the first were classified as experiencing an intrapartum change in presentation. Characteristics associated with intrapartum presentation change in a univariate analysis with a P value ≤.10 were then evaluated in a multivariate logistic regression model. Four-hundred fifty women met inclusion criteria, of whom 55 (12%) had intrapartum presentation change of the second twin. Women experiencing intrapartum presentation change were more likely to be multiparous (69% compared with 47%, P<.01) and to have had a change in the presentation of the second twin between the most recent antepartum ultrasonogram and the ultrasonogram done on admission to labor and delivery (11% compared with 4%, P=.04). In an adjusted analysis, multiparity and gestational age less than 34 weeks were significantly associated with presentation change (adjusted odds ratio [OR] 2.9, 95% CI 1.5-5.6 and adjusted OR 2.6, 95% CI 1.1-5.9, respectively). Women with intrapartum presentation change were more likely to undergo cesarean delivery for their second twin (44% compared with 7%, P<.01) with an adjusted OR of 10.50 (95% CI 5.20-21.20) compared with those with stable intrapartum presentation. Twenty of the 24 (83%) cesarean deliveries performed in the intrapartum presentation change group were done for issues related to malpresentation. Multiparity and gestational age less than 34 weeks are associated with intrapartum presentation change of the second twin.

Epidemiology of pituitary pars intermedia dysfunction: A systematic literature review of clinical presentation, disease prevalence and risk factors.

Ireland, J L; McGowan, C M

2018-05-01

Pituitary pars intermedia dysfunction (PPID) is caused by an age-related degenerative disease of dopaminergic neurones. Despite its importance in equine practice, available information regarding its epidemiology is limited. This systematic review aimed to assess published literature to evaluate available evidence regarding the clinical presentation, prevalence and risk factors for PPID in horses and ponies. Electronic database searches were undertaken using a range of terms, and English language publications published prior to August 2016 were included. Both authors independently reviewed screened papers for inclusion, extracted data, and assessed the quality of reporting using predefined criteria. Data were extracted using modified critically appraised topic data collection forms. Meta-analysis was not undertaken due to marked between-study variations. Following removal of duplicate records, of 358 published papers yielded by the search, 97 abstracts were screened for eligibility and 29 publications meeting inclusion criteria were included in the review. Most studies reviewed were case series or cross-sectional studies, with considerable variation in study populations and PPID case definition. Hypertrichosis and/or other hair coat abnormalities, laminitis and epaxial muscle wastage or muscle atrophy are the most frequently reported clinical signs, with prevalence of these signs increasing with increasing horse age. The most robust prevalence estimates for PPID were 21.2% in horses and ponies aged ≥15 years and 2.9% amongst the general equine population. Findings regarding breed and sex predispositions were equivocal and only increasing age has been identified as a significant risk factor for PPID. Copyright © 2018 The Authors.

a) to examine the demographic and clinical characteristics of repeat-presentations to an adolescent urgent psychiatric clinic, and b) to compare them with single-time presentation. This 18-month retrospective study compared repeat-presenters to age and gender matched single-time presenters. Demographic variables included age gender and ethnicity. Clinical variables included reason for referral, family history, diagnosis, recommendations and compliance. Data were analyzed using descriptive statistics, McNemar's Chi-square tests for matched pairs, and conditional logistic regression. Of 624 assessments 24% (N=151) were repeat-presentations. Compared with single-presentation, repeat-presentation group had a higher proportion of Aboriginal youth (X2 (1) = 108.28 p < 0.01), a higher proportion in special educational placement (X2 (1) = 6.82, p < 0.01), a higher proportion with a family history of anxiety disorders (X2 (1) = 10.62, p = 0.01) and substance use disorder (X2 (1) = 18.99, p < 0.01). Conditional logistic regression results suggested that repeat-presentation group had higher odds of past hospital admission (OR: 3.50, p < 0.01) higher odds of family history of mood disorders (OR: 4.86, p < 0.01) and of antisocial disorders (OR: 4.97, p = 0.02), and lower odds of recommendation compliance (OR: 0.10, p < 0.01). Repeat-presentations for urgent psychiatric consultation constitute a quarter of referrals to the urgent psychiatric clinic. Identifying and addressing factors that contribute to repeat-presentations may, assist in improving treatment compliance by ensuring focused interventions and service delivery for these youth. In turn, this will improve access to the limited urgent services for other youth.

Pathology and clinical presentation of friction injuries: case series and literature review.

PubMed

Berke, Christine Thies

2015-01-01

Effective wound management is dependent, in part, on identification and correction of causative factors. Trunk wounds can be caused by pressure, shear, moisture, friction, or some combination of these factors. Wounds caused by moisture and/or friction are frequently mislabeled as pressure ulcers. This article presents a series of 45 patients who developed skin injuries on the medial buttocks and/or posterior thighs that the author believes were caused primarily by friction damage to the skin. The lesions were not located over palpable bony prominences and are therefore unlikely to be pressure ulcers. They were not located in skin folds and are unlikely to represent intertriginous dermatitis. Clinical data related to these 45 patients are presented, as are the location and characteristics of the lesions. These characteristics are discussed in relation to current literature regarding the pathology and clinical presentation of wounds caused by pressure, moisture, and friction. It is critical for wound clinicians and staff nurses to accurately identify the etiology of any wound. Wounds located on fleshy prominences exposed to repetitive friction should be labeled as friction injuries.

Clinical presentation and in-hospital death in acute pulmonary embolism: does cancer matter?

Cancer is one of the most common risk factors for acute pulmonary embolism (PE), but only few studies report on the short-term outcome of patients with PE and a history of cancer. The aim of the study was to assess whether a cancer diagnosis affects the clinical presentation and short-term outcome in patients hospitalized for PE who were included in the Italian Pulmonary Embolism Registry. All-cause and PE-related in-hospital deaths were also analyzed. Out of 1702 patients, 451 (26.5 %) of patients had a diagnosis of cancer: cancer was known at presentation in 365, or diagnosed during the hospital stay for PE in 86 (19 % of cancer patients). Patients with and without cancer were similar concerning clinical status at presentation. Patients with cancer less commonly received thrombolytic therapy, and more often had an inferior vena cava filter inserted. Major or intracranial bleeding was not different between groups. In-hospital all-cause death occurred in 8.4 and 5.9 % of patients with and without cancer, respectively. At multivariate analysis, cancer (OR 2.24, 95 % CI 1.27-3.98; P = 0.006) was an independent predictor of in-hospital death. Clinical instability, PE recurrence, age ≥75 years, recent bed rest ≥3 days, but not cancer, were independent predictors of in-hospital death due to PE. Cancer seems a weaker predictor of all-cause in-hospital death compared to other factors; the mere presence of cancer, without other risk factors, leads to a probability of early death of 2 %. In patients with acute PE, cancer increases the probability of in-hospital all-cause death, but does not seem to affect the clinical presentation or the risk of in-hospital PE-related death.

Clinical presentation of neurocysticercosis-related epilepsy.

Duque, Kevin R; Burneo, Jorge G

2017-11-01

Neurocysticercosis (NCC) is the most common parasitic infection of the central nervous system and a major risk factor for seizures and epilepsy. Seizure types in NCC vary largely across studies and seizure semiology is poorly understood. We discuss here the studies regarding seizure types and seizure semiology in NCC, and examine the clinical presentation in patients with NCC and drug-resistant epilepsy. We also provide evidence of the role of MRI and EEG in the diagnosis of NCC-related epilepsy. Focal seizures are reported in 60-90% of patients with NCC-related epilepsy, and around 90% of all seizures registered prospectively are focal not evolving to bilateral tonic-clonic seizures. A great number of cases suggest that seizure semiology is topographically related to NCC lesions. Patients with hippocampal sclerosis and NCC have different clinical and neurophysiological characteristics than those with hippocampal sclerosis alone. Different MRI protocols have allowed to better differentiate NCC from other etiologies. Lesions' stages might account on the chances of finding an interictal epileptiform discharge. Studies pursuing the seizure onset in patients with NCC are lacking and they are specially needed to determine both whether the reported events of individual cases are seizures, and whether they are related to the NCC lesion or lesions.

To describe the clinical characteristics, staging and presentation of patients with familial exudative vitreoretinopathy (FEVR) in our clinical practice over the last 25 years. Case series, retrospective review. We included 273 eyes of 145 patients. Data collected from charts included gender, gestational age at birth, birthweight, age at presentation, referring diagnosis, family history, prior ocular surgery, and clinical presentation in each eye. Eyes with invasive posterior segment procedures before initial presentation were excluded. Demographics on presentation and clinical staging. Patients were slightly male predominant (57%) with a mean birthweight of 2.80 kg (range, 740 g-4.76 kg), mean gestational age of 37.8 weeks (range, 25-42), and mean age at presentation of almost 6 years (range, <1 month-49 years). A positive family history of FEVR was obtained in 18% of patients. A positive family history for ocular disease consistent with but not diagnosed as FEVR was obtained in an additional 19%. Stage 1 FEVR was identified in 45 eyes, stage 2 in 33 eyes, stage 3 in 42 eyes, stage 4 in 89 eyes, and stage 5 in 44 eyes. Radial retinal folds were seen in 77 eyes, 64 of which were temporal or inferotemporal in location. The FEVR patient population is remarkable for the wide range of age at presentation, gestational age, and birthweight. Although a positive family history on presentation may support the diagnosis of FEVR, a negative family history is of little help. The majority of retinal folds extended radially in the temporal quadrants, but radial folds were seen in almost all quadrants. Fellow eyes demonstrated a wide variation in symmetry. The presentation of FEVR may mimic the presentation of other pediatric and adult vitreoretinal disorders, and careful examination is often crucial in making the diagnosis of FEVR.

The clinical manifestations of acute Q fever may differ markedly from country to country. In this regard, fever and hepatitis seem to be the dominant clinical features of acute Coxiella burnetii infection in Lanzarote, Canary Islands. A possible interaction between environmental factors and some strains of C. burnetii could explain the different clinical presentations of acute Q fever.

To investigate the factors associated with adverse clinical features presented by drug overdose/self-poisoning patients and the treatments provided. Historical patient records collected over 3 months from ambulance crews attending non-fatal overdoses/self-poisoning incidents were reviewed. Logistic regression was used to investigate predictors of adverse clinical features (reduced consciousness, obstructed airway, hypotension or bradycardia, hypoglycaemia) and treatment. Of 22,728 calls attended to over 3 months, 585 (rate 26/1000 calls) were classified as overdose or self-poisoning. In the 585 patients identified, paracetamol-containing drugs were most commonly involved (31.5%). At least one adverse clinical feature occurred in 103 (17.7%) patients, with higher odds in men and opiate overdose or illegal drugs. Older patients and patients with reduced consciousness were more likely to receive oxygen. The latter also had a greater chance of receiving saline. Non-fatal overdose/self-poisoning accounted for 2.6% of patients attended by an ambulance. Gender, illegal drugs or opiates were important predictors of adverse clinical features. The treatments most often provided to patients were oxygen and saline.

Intracranial aneurysms are arterial anomalies affecting 2% to 3% of the general population in the world and these ruptures are associated with a high mortality. Some risk factors, such as age, gender, smoking, alcohol, hypertension and familial history are associated with the number of aneurysms and their size. In addition, inflammatory processes within the blood vessels of the brain can activate matrix metalloproteinase-9 (MMP-9), which degrades various components of the extracellular matrix, such as elastin. Thereby, this work has aimed at evaluating the relationship between plasma MMP-9 levels and the risk factors that are associated with intracranial aneurysm, as well as investigating the aneurysm statuses (ruptured and unruptured) and comparing them with the control volunteers. Between August 2014 to June 2016, blood samples were collected from 282 patients (204 ruptured and 78 unruptured saccular intracranial aneurysms) and 286 control volunteers. The MMP-9 plasma levels were measured by ELISA. Statistical analyzes were performed with SPSS software when using parametric or nonparametric tests, after the normality tests. Higher levels of MMP-9 were found in the aneurysm groups as a whole and when they were stratified by rupture status, then compared with the control group (p < 0.0001). When stratifying them by diameter, those smaller than 7 mm presented high levels of MMP-9 (p < 0.0001), especially in the ruptured ones. As for risk factors, hypertension and smoking were the most important. However, hypertension was mostly associated with the ruptured aneurysms (p < 0.0001). High levels of MMP-9 were found in smaller ruptured and unruptured intracranial aneurysms (<7 mm) with strongest statistical associations than other sizes, especially when associated with smoking and hypertension.

Nodal marginal zone lymphoma (NMZL) is a rare type of B-cell non-Hodgkin lymphoma. This study assessed the clinical features of 56 patients with NMZL in comparison to 46 patients with follicular lymphoma (FL). Patients with NMZL and FL had a largely similar clinical presentation, but patients with FL had a higher disease stage at presentation, more frequent abdominal lymphadenopathy and bone marrow involvement, and showed more common transformation into diffuse large B-cell lymphoma (DLBCL) during the course of disease. Overall survival and event-free survival were similar for patients with NMZL and FL, but factors associated with worse prognosis differed between the two groups. Transformation into DLBCL was associated with a significantly poorer outcome in both groups, but the phenotypes were different: DLBCL arising in FL was mainly of germinal center B-cell phenotype, whereas DLBCL arising in NMZL was mainly of non-germinal center B-cell phenotype.

Nasopharyngeal angiofibroma (NA) is a rare, vascular tumor affecting adolescent males. Due to aggressive local growth, skull base location and risk of profound hemorrhage, NA is a challenge for surgeons. Angiofibromas have been sporadically described in extanasopharyngeal locations. We review ten cases of extranasopharyngeal angiofibroma (ENA) and discuss the incidence, clinical presentation and management of this pathology. The group consisted of 4 males and 5 females aged 8-49. There were 7 patients with nasal angiofibroma, 1 patient with laryngeal angiofibroma, 1 patient with oral angiofibroma and another patient with infratemporal fossa tumor. In patients with nasal angiofibroma most common presenting symptoms were nasal obstruction and epistaxis. Patients with laryngeal angiofibroma suffered from mild dysphagia and patients with the infratemporal fossa tumor had painless cheek swelling. In four patients with nasal tumor computed tomography (CT) demonstrated mass with strong to intermediate contrast enhancement. In one patient with nasal tumor carotid angiography demonstrated pathological vessels without intensive tumor blush. Infratemporal fossa tumor showed intensive contrast enhancement on CT and magnetic resonance imaging (MRI) scans, and abundant vascularity on angiography. Laryngeal and oral angiofibroma required no radiological imaging. Three nasal tumors were evaluated before introduction of CT to clinical practice. All patients underwent surgery. No recurrences developed. ENAs differ significantly from NAs regarding clinical and radiological presentations. They lack typical clinical and radiological features as they develop in all age groups and in females, may be less vascularised, arise from various sites and produce a variety of symptoms.

To assess whether family history of rheumatoid arthritis (RA), among the strongest risk factors for developing RA, also carries information on the clinical presentation and treatment response. The prospective Swedish Rheumatology register was linked to family history of RA, defined as diagnosed RA in any first-degree relative, ascertained through the Swedish Multi-Generation and Patient registers. Clinical presentation was examined among patients with early RA 2000-2011 (symptom onset <12 months before inclusion, N=6869), and response to methotrexate (MTX) monotherapy in the subset starting this treatment (N=4630). Response to tumour necrosis factor inhibitors (TNFi) was examined among all patients with RA starting a TNFi as the first biological disease-modifying antirheumatic drug 2000-2011 (N=9249). Association of family history with clinical characteristics, drug survival, European League Against Rheumatism (EULAR) response and change in disease activity at 3 and 6 months was estimated using linear and generalised logistic regression models. Correlation in relatives' response measures was also assessed. Patients with early RA with family history of RA were more often rheumatoid factor positive, but with no other clinically meaningful differences in their clinical presentation. Family history of RA did not predict response to MTX or TNFi, with the possible exception of no versus good EULAR response to TNFi at 6 months (OR=1.4, 95% CI 1.1 to 1.7). Having a relative who discontinued TNFi within a year increased the odds of doing the same (OR=3.7, 95% CI 1.8 to 7.5), although we found no significant familial correlations in change in disease activity measures. Family history of RA did not modify the clinical presentation of RA or predict response to standard treatment with MTX or TNFi. Treatment response, particularly drug survival, may itself be familial.

Background Social cognition is consistently impaired in people with schizophrenia, separable from general neurocognition, predictive of real-world functioning, and amenable to psychosocial treatment. Few studies have empirically examined its underlying factor structure. Aims The present study (1) examines the factor structure of social cognition in both a sample of individuals with schizophrenia-spectrum disorders and non-clinical controls, and (2) explores relationships of factors to neurocognition, symptoms and functioning. Method A factor analysis was conducted on social cognition measures in a sample of sixty-five individuals with schizophrenia or schizoaffective disorder, and fifty control participants. The resulting factors were examined for their relationships to symptoms and functioning. Results Results suggested a two-factor structure in the schizophrenia sample (social cognition skill and hostile attributional style) and a three-factor structure in the non-clinical sample (hostile attributional style, higher-level inferential processing, and lower-level cue detection). In the schizophrenia sample, the social cognition skill factor was significantly related to negative symptoms and social functioning, while hostile attributional style predicted positive and general psychopathology symptoms. Conclusions The factor structure of social cognition in schizophrenia separates hostile attributional style and social cognition skill, and each show differential relationships to relevant clinical variables in schizophrenia.

Autoimmune hepatitis (AIH) is characterized by progressive inflammation and necrosis of hepatocytes and eventually leads to a variety of phenotypes, including acute liver dysfunction, chronic progressive liver disease, and fulminant hepatic failure. Although the precise mechanisms of AIH are unknown, environmental factors may trigger disease onset in genetically predisposed individuals. Patients with the recently established entity of AIH with acute presentation often display atypical clinical features that mimic those of acute hepatitis forms even though AIH is categorized as a chronic liver disease. The aim of this study was to identify the precise clinical features of AIH with acute presentation. Eighty-six AIH patients with acute presentation were retrospectively enrolled from facilities across Japan and analyzed for clinical features, histopathological findings, and disease outcomes. Seventy-five patients were female and 11 were male. Patient age ranged from adolescent to over 80 years old, with a median age of 55 years. Median alanine transaminase (ALT) was 776 U/L and median immunoglobulin G (IgG) was 1671 mg/dL. There were no significant differences between genders in terms of ALT (P = 0.27) or IgG (P = 0.51). The number of patients without and with histopathological fibrosis was 29 and 57, respectively. The patients with fibrosis were significantly older than those without (P = 0.015), but no other differences in clinical or histopathological findings were observed. Moreover, antinuclear antibody (ANA)-positive (defined as × 40, N = 63) and -negative (N = 23) patients showed no significant differences in clinical or histopathological findings or disease outcomes. Twenty-five patients experienced disease relapse and two patients died during the study period. ALP ≥ 500 U/L [odds ratio (OR) 3.20; 95% confidence interval (CI) 1.12-9.10; P < 0.030] and GGT ≥ 200 U/L (OR 2.98; 95% CI 1.01-8.77; P = 0.047) were identified as

SEER recently released patient Gleason scores at biopsy/transurethral resection of the prostate. For the first time this permits accurate assessment of prostate cancer presentation and treatment according to clinical factors at diagnosis. We used the SEER database to identify men diagnosed with localized prostate cancer in 2010 who were assigned NCCN(®) risk based on clinical factors. We identified sociodemographic factors associated with high risk disease and analyzed the impact of these factors along with NCCN risk on local treatment. Of the 42,403 men identified disease was high, intermediate and low risk in 38%, 40% and 22%, respectively. On multivariate analysis patients who were older, nonwhite, unmarried or living in a county with a higher poverty rate were more likely to be diagnosed with high risk disease (each p <0.05). Of the 38,634 men in whom prostate cancer was the first malignancy 23% underwent no local treatment, 40% were treated with prostatectomy, 36% received radiation therapy and 1% underwent local tumor destruction, predominantly cryotherapy. On multivariate analysis patients who were older, black, unmarried or living in a county with a higher poverty rate, or who had low risk disease were less likely to receive local treatment (each p <0.05).

Objectives To understand whether aviation-derived human factors training is acceptable and useful to healthcare professionals. To understand whether and how healthcare professionals have been able to implement human factors approaches to patient safety in their own area of clinical practice. Methods Qualitative, longitudinal study using semi-structured interviews and focus groups, of a multiprofessional group of UK NHS staff (from the emergency department and operating theatres) who have received aviation-derived human factors training. Results The human factors training was evaluated positively, and thought to be both acceptable and relevant to practice. However, the staff found it harder to implement what they had learned in their own clinical areas, and this was principally attributed to features of the informal organisational cultures. Conclusions In order to successfully apply human factors approaches in hospital, careful consideration needs to be given to the local context and informal culture of clinical practice. PMID:24631959

To evaluate the clinical presentation and comorbidities of hypertensive crisis in our own population. In this cohort based study, we investigate the clinical presentation and comorbidities of hypertensive crisis by evaluating the data collected between January and April 2009. We included 154 patients admitted with systolic and diastolic blood pressure of >179 mm Hg and >119 mm Hg (based on the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure criteria) in the Department of Internal Medicine, Salmaniya Medical Complex, Kingdom of Bahrain. In the study population, 64.3% had hypertensive urgency (blood pressure elevation without end organ damage) and 35.7% had hypertensive emergency (blood pressure elevation with end organ damage). The mean age group was 45-65 years (56% of the study population) and more men were affected than women (100:54). Shortness of breath and neurological deficits had a strong statistical association with hypertensive emergency, and headache and blurring of vision had the same tendency toward hypertensive urgency. Diabetes mellitus was an independent risk factor for hypertensive crisis. Most of the studied patients were known hypertensive. Diabetes mellitus is powerful predictor for hypertensive crisis. Dyspnea and neurological deficits have significant statistical correlation with hypertensive emergencies.

Dental caries is a major disease that threaten human's oral healthy severely with the characteristics of high incidence, low rate of treatment and high rate of retreatment. At present, restorative treatment remains the main method for caries treatment. With the development of the Minimally Invasive Cosmetic Dentistry (MICD), reasonable application of various treatment technologies, maximum preservation of tooth tissues and realizing the maximization of treatment effects become problems that call for immediate solution in dental clinics. In addition, there still exist a large number of old restorations that need standard retreatments. Here, some difficulty influence factors of dental caries clinical treatment such as systemic and oral factors, individual caries susceptibility, treatment technologies and materials, retreatment methods of old restorations and technique sensitivity are analyzed, and corresponding processing strategies are also put forward.

Dementia with Lewy bodies (DLB) is a heterogeneous disease in which clinical presentation, symptoms, and evolution widely varies between patients. To investigate the existence of clinical subtypes in DLB based on the initial clinical presentation. 81 patients with a clinical diagnosis of probable DLB were consecutively included. All patients underwent a neurological evaluation including a structured questionnaire about neuropsychiatric symptoms and sleep, an assessment of motor impairment (Unified Parkinson Disease Rating Scale subscale III), and a formal neuropsychological evaluation. Onset of core symptoms (hallucinations, parkinsonism, and fluctuations) and dementia were systematically reviewed from medical records. We applied a K-means clustering method based on the initial clinical presentation. Cluster analysis yielded three different groups. Patients in cluster I (cognitive-predominant, n = 46) presented more frequently with cognitive symptoms (95.7%, n = 44, p < 0.001), and showed a longer duration from onset to DLB diagnosis (p < 0.001) than the other clusters. Patients in cluster II (neuropsychiatric-predominant, n = 22) were older at disease onset (78.1±5 versus 73.6±6.1 and 73.6±4.2 in clusters I and III, respectively, both p < 0.01), presented more frequently with psychotic symptoms (77.3%, n = 17), and had a shorter duration until the onset of hallucinations (p < 0.001). Patients in cluster III (parkinsonism-predominant, n = 13) showed a shorter time from onset to presence of parkinsonism (p < 0.001) and dementia (0.008). Three subtypes of clinical DLB can be defined when considering the differential initial presentations. The proposed subtypes have distinct clinical profiles and progression patterns.

Capgras syndrome: a review of the neurophysiological correlates and presenting clinical features in cases involving physical violence.

PubMed

Bourget, Dominique; Whitehurst, Laurie

2004-11-01

Acts of violence have been frequently reported in cases of Capgras syndrome (CS), a misidentification syndrome characterized by the delusional belief that imposters have replaced people familiar to the individual. CS has been observed in many neuropsychiatric and organic disorders, and neuroimaging studies indicate an association between CS and right hemisphere abnormalities. However, CS has received limited attention from a forensic psychiatric perspective. We propose that elucidating demographic and clinical features noted in cases of violence secondary to CS may highlight important factors in the progression of CS to violence. We review the neurophysiological correlates and clinical factors observed in CS and present characteristics of a series of cases that demonstrate the potential of CS patients for severe physical violence toward the misidentified person. For patients with CS involving assault, we present and discuss commonly reported demographic and clinical features that may contribute to an increased risk for violence. An understanding of the presenting clinical features of CS resulting in aggressive acts may assist clinicians to assess the potential for violence in these patients.

Background Patients with acute decompensated heart failure (ADHF) often wait a considerable amount of time before going to the hospital. Prior studies have examined the reasons why such delays may occur, but additional studies are needed to identify modifiable factors contributing to these delays. Purpose To describe care-seeking delay times, factors associated with prolonged delay, and patient's thoughts and actions in adult men and women hospitalized with ADHF. Methods We surveyed 1,271 patients hospitalized with ADHF at 8 urban medical centers between 2007 and 2010. Results The average age of our study population was 73 years, 47% were female, and 72% had prior heart failure. The median duration of pre-hospital delay prior to hospital presentation was 5.3 hours. Patients who delayed longer than the median were older, more likely to have diabetes, peripheral edema, to have symptoms that began in the afternoon, and to have contacted their medical provider(s) about their symptoms. Prolonged care seekers were less likely to have attributed their symptoms to ADHF, less likely to want to have bothered their doctor or family, and were more likely to be concerned about missing work due to their illness (all p values<0.05). Conclusions Care-seeking delays are common among patients with ADHF. A variety of factors contribute to these delays which in some cases may represent efforts to manage ADHF symptoms at home. More research is needed to better understand the detrimental effects of these delays and how best to encourage timely care-seeking behavior in the setting of ADHF. PMID:23474108

A Glimpse into Uveitis in the Aging Eye: Pathophysiology, Clinical Presentation and Treatment Considerations.

PubMed

Akinsoji, Elizabeth; Goldhardt, Raquel; Galor, Anat

2018-05-01

Uveitis describes a group of inflammatory conditions of the eye that have various underlying causes and clinical presentations. Susceptibilities to uveitis in the elderly may be attributed to age-related risk factors such as immunosenescence, increased immunological inflammatory mediators, and autoimmunity. Overall, anterior uveitis is more common than posterior and panuveitis in the general population and also in the elderly. Some causes of uveitis in the elderly are herpes simplex virus, ocular ischemic syndrome, sarcoidosis, and central nervous system lymphoma, and these will be discussed in detail herein. Eye care professionals need to consider the wide differential for uveitis, obtain the appropriate history, conduct a detailed clinical examination, and tailor management to the clinical presentation and underlying cause of disease. The challenges of polypharmacy and nonadherence in the elderly impact patient outcomes and must be taken into consideration when considering treatment.

This study aimed to determine the prevalence of diabetic foot ulcer and high risk for ulceration, describe the clinical presentation, and identify factors associated with diabetic foot ulcer in the Southwest regional hospitals of Cameroon. In this cross-sectional study, data were collected using a structured questionnaire administered to consecutive patients with diabetes. Findings from detailed foot examination were recorded. Diabetic foot ulcer was diagnosed according to the International Working Group on Diabetic Foot (IWGDF) definition. Data were analyzed with Stata IC version 12. Of the 203 participants included, 63.1% were females. Age ranged from 26 to 96 years. The median duration of diabetes was 4.0 years (interquartile range 1.0-8.0 years). The prevalence of diabetic foot ulcer was 11.8% (24), of whom 29.2% (7) had high grade (grades 2 to 4), and most of the ulcers 58.3% (14) were located at the plantar region. The prevalence of high risk for ulceration was 21.8% (39). Loss of protective sensation (OR = 3.73, 95% CI = 1.43-9.71; P = .007), and peripheral arterial disease (OR = 3.48, 95% CI = 1.14-10.56; P = .028) were independently associated with diabetic foot. Diabetic foot ulcer is a common complication among patients with diabetes attending these regional hospitals. Loss of protective sensation, and peripheral arterial disease increase the odds of having diabetic foot ulcer, and we suggest them as the main target of interest for prevention.

While cerebral edema and diabetic ketoacidosis (DKA) in type 1 diabetes (T1DM) have well-described acute effects on cognition, little is known about the impact of clinical presentation on longer term cognitive outcomes. We hypothesized that clinical factors (degree of hyperglycemia exposure and DKA) at the time of diagnosis would relate to cognition within 3.5 months later in children with T1DM. Cognitive testing was performed on children 7-17 years old with T1DM (n = 66) within 3.5 months of diagnosis and siblings without T1DM (n = 33). Overall intelligence, processing speed, and memory (including a sensitive long-delay spatial memory test; spatial delayed response or SDR) were assessed. Medical records were reviewed for hemoglobin A1c (HbA1c), DKA status, and other clinical factors at diagnosis. Within the group with T1DM, 17 children presented in DKA and 49 did not. After adjusting for age, gender, and socioeconomic status, the subgroup with T1DM and DKA at diagnosis performed worse on the long-delay SDR task compared to sibling controls (p = 0.006). In addition, within the group with T1DM, higher HbA1c at diagnosis was associated with worse performance on the long-delay SDR task (p = 0.027). Performance on the other cognitive tasks was not different across groups or subgroups. DKA and degree of hyperglycemia exposure at diagnosis have implications for long-delay spatial memory function within 3.5 months of diagnosis. These findings suggest that early detection of T1DM, which decreases risk for prolonged exposure to hyperglycemia and DKA, may avoid negative effects on memory function. © 2015 John Wiley & Sons A/S.

India is currently in the fourth stage of epidemiological transitions where cardiovascular disease is the leading cause of mortality and morbidity. Purpose of the present study was to assess the risk factors, clinical presentation, angiographic profile including severity, and in-hospital outcome of very young adults (aged ≤ 30 years) with first acute myocardial infarction (AMI). Total of 1,116 consecutive patients with ST-segment elevation acute myocardial infarction (STEMI) were studied between March 2013 and February 2015 at LPS Institute of Cardiology, Kanpur, Uttar Pradesh, India. Mean age of the patients was 26.3 years. Risk factors were smoking (78.5%), family history of premature coronary artery disease (CAD) (46.8%), obesity (39.1%), physical inactivity (38.7%) and stressful life events (29.6%). The most common symptom and presentation was chest pain and anterior wall myocardial infarction (AWMI) in 94.8% and 58.8%, respectively. About 80.6% of patients had obstructive CAD with single vessel disease (57.6%), double-vessel disease (12.9%) and left main involvement (3.2%). Left anterior descending (LAD) was commonest culprit artery (58.1%) followed by right coronary artery in 28.2%. In-hospital mortality was 2.8%. Percutaneous coronary intervention was performed in 71.6% of patients. Median number and length of stent were 1.18 and 28 ± 16 mm, respectively. AMI in very young adult occurred most commonly in male. Smoking was the most common risk factor. AWMI owing to LAD artery involvement was the most common presentation. Mean time of presentation after symptom onset was 16.9 hours. In contrast to western population, it is characterised by earlier onset, delayed presentation, more severity, diffuse disease, and more morbidity but with favourable in-hospital mortality.

Childhood polycythemias/erythrocytoses: classification, diagnosis, clinical presentation, and treatment.

PubMed

Cario, H

2005-03-01

Polycythemias or erythrocytoses in childhood and adolescence are very rare. Systematic data on the clinical presentation and laboratory evaluations as well as on treatment regimens are sparse. The diagnostic program in absolute erythrocytosis includes extensive clinical, hematological, biochemical, and molecular biological examinations which should be applied following a stepwise algorithm. Absolute erythrocytoses are usually subdivided into primary and secondary forms. Primary erythrocytosis is a condition in which the erythropoietic compartment is expanding independently of extrinsic influences or by responding inadequately to them. Primary erythrocytoses include primary familial and congenital polycythemia (PFCP) due to mutations of the erythropoietin (Epo) receptor gene and the myeloproliferative disorder polycythemia vera. Secondary erythrocytoses are driven by hormonal factors (predominantly by Epo) extrinsic to the erythroid compartment. The increased Epo secretion may represent either a physiologic response to tissue hypoxia, an abnormal autonomous Epo production, or a dysregulation of the oxygen-dependent Epo synthesis. Congenital secondary erythrocytoses are caused, e.g., by hemoglobin variants with increased oxygen affinity, by 2,3-bisphosphoglycerate deficiency, or by mutations in the von Hippel-Lindau gene associated with a disturbed oxygen-dependent regulation of Epo synthesis.

Clinical spectrum of rhabdomyolysis presented to pediatric emergency department

PubMed Central

2013-01-01

Background Rhabdomyolysis is a potentially life-threatening syndrome that can develop from a variety of causes. The aim of the work is to analyze the clinical spectrum and to evaluate the prevalence of various etiologies in children, who present to the emergency department (ED) with rhabdomyolysis. Methods During a 6-year study period, we retrospectively analyzed the medical charts of patients, aged 18 years or younger, with a definite diagnosis of rhabdomyolysis and serum creatinine phosphokinase (CK) levels greater than 1000IU/L. We analyzed the clinical spectrum and evaluated the potential risk factors of acute renal failure (ARF). Results Thirty-seven patients (mean age = 10.2 ± 5.5 years), including 26 males and 11 females, were enrolled in the study. Two of the most common presented symptoms in these 37 patients were muscle pain and muscle weakness (83.8% and 73%, respectively). Dark urine was reported in only 5.4% of the patients. The leading cause of rhabdomyolysis in the 0- to 9-year age group was presumed infection, and the leading cause in the 10- to 18-year age group was trauma and exercise. The incidence of ARF associated with rhabdomyolysis was 8.1 % and no child needed for renal replacement therapy (RRT). We did not identify any reliable predictors of ARF or need for RRT. Conclusions The classic triad of symptoms of rhabdomyolysis includes myalgia, weakness and dark urine are not always presented in children. The cause of rhabdomyolysis in younger age is different from that of teenager group. However, the prognosis of rhabdomyolysis was good with appropriate management. PMID:24004920

Arboviruses are an emerging group of viruses that are causing increasing health concerns globally, including in Europe. Clinical presentation usually consists of a nonspecific febrile illness that may be accompanied by rash, arthralgia and arthritis, with or without neurological or haemorrhagic syndromes. The range of differential diagnoses of other infectious and noninfectious aetiologies is broad, presenting a challenge for physicians. While knowledge of the geographical distribution of pathogens and the current epidemiological situation, incubation periods, exposure risk factors and vaccination history can help guide the diagnostic approach, the nonspecific and variable clinical presentation can delay final diagnosis. This narrative review aims to summarize the main clinical and laboratory-based findings of the three most common imported arboviruses in Europe. Evidence is extracted from published literature and clinical expertise of European arbovirus experts. We present three cases that highlight similarities and differences between some of the most common travel-related arboviruses imported to Europe. These include a patient with chikungunya virus infection presenting in Greece, a case of dengue fever in Turkey and a travel-related case of Zika virus infection in Romania. Early diagnosis of travel-imported cases is important to reduce the risk of localized outbreaks of tropical arboviruses such as dengue and chikungunya and the risk of local transmission from body fluids or vertical transmission. Given the global relevance of arboviruses and the continuous risk of (re)emerging arbovirus events, clinicians should be aware of the clinical syndromes of arbovirus fevers and the potential pitfalls in diagnosis.

Evidence-based healthcare (EBHC) emphasizes the integration of the best research evidence with patient values, specialist suggestions, and clinical circumstances during the process of clinical decision-making. EBHC is a recognized core competency in modern healthcare. Nursing is a professional discipline of empirical science that thrives in an environment marked by advances in knowledge and technology in medicine as well as in nursing. Clinical nurses must elevate their skills and professional qualifications, provide efficient and quality health services, and promote their proficiency in EBHC. The Institute of Medicine in the United States indicates that evidence-based research results often fail to disseminate efficiently to clinical decision makers. This problem highlights the importance of better promoting the evidence-based healthcare fundamentals and competencies to frontline clinical nurses. This article describes the historical background and present development of evidence-based healthcare from the perspective of modern clinical nursing in light of the importance of evidence-based healthcare in clinical nursing; describes the factors associated with evidence-based healthcare promotion; and suggests strategies and policies that may improve the promotion and application of EBHC in clinical settings. The authors hope that this paper provides a reference for efforts to improve clinical nursing in the realms of EBHC training, promotion, and application.

Epidemiology, genetic, natural history and clinical presentation of giant cerebral aneurysms.

Giant cerebral aneurysms represent 5% of intracranial aneurysms, and become symptomatic between 40 and 70 years with a female predominance. In the paediatric population, the giant aneurysm rate is higher than in the adult population. Classified as saccular, fusiform and serpentine, the natural history of giant cerebral aneurysms is characterized by thrombosis, growth and rupture. The pathogenesis of these giant aneurysms is influenced by a number of risk factors, including genetic variables. Genome-wide association studies have identified some chromosomes highlighting candidate genes. Although these giant aneurysms can occur at the same locations as their smaller counterparts, a predilection for the cavernous location has been observed. Giant aneurysms present with symptoms caused by a mass effect depending on their location or by rupture; ischemic manifestations rarely reveal the aneurysm. If the initial clinical descriptions have been back up by imagery, the clinical context with a pertinent analysis of the risk factors remain the cornerstone for the management decisions of these lesions. Five year cumulative rupture rates for patients with giant aneurysm were 40% for those located on the anterior part of circle of Willis and 50% for those on the posterior part. The poor outcome of untreated patients justifies the therapeutic risks. Copyright © 2015. Published by Elsevier Masson SAS.

A Supernumerary Nipple-Like Clinical Presentation of Lymphangioma Circumscriptum.

Lymphangioma circumscriptum is a superficially localized variant of lymphangioma. The characteristic clinical presentation is a "frogspawn" grouping of vesicles or papulovesicles on the proximal limb or limb girdle areas. Though most lymphangiomas develop congenitally, the lymphangioma circumscriptum subtype is known to present in adults. We report a case of lymphangioma circumscriptum on the left inframammary area of an African American female with an unusual supernumerary nipple-like clinical presentation. Our patient presented with a firm, smooth, hypopigmented papule, and the clinical diagnosis of keloid was made initially. However, she returned reporting growth of the lesion and was noted to have a firm, exophytic, lobulated, pink to skin-colored nodule. Histopathological examination demonstrated dilated lymphatic vessels, consistent with the diagnosis of lymphangioma. The presentation as a firm, hypopigmented papule and later exophytic, lobulated, skin-colored nodule in our case represents a clinical presentation of lymphangioma circumscriptum not previously described in the literature. Correct diagnosis in lymphangioma circumscriptum is vital, as recurrence following surgical resection and secondary development of lymphangiosarcoma and squamous cell carcinoma following treatment with radiation have been reported. Thus, it is important to consider lymphangioma circumscriptum in the differential of similar lesions in the future to allow appropriate diagnosis, treatment, and monitoring.

Improving the timely recognition and response to clinical deterioration is a critical challenge for clinicians, educators, administrators and researchers. Clinical deterioration leading to Rapid Response Team review is associated with poor patient outcomes. A range of factors associated with clinical deterioration and its outcomes have been identified, and may help with early identification of deteriorating patients. However, the relative importance of each factor on the development of clinical deterioration is unknown. To identify the relative importance of factors contributing to the development of clinical deterioration in ward patients, as perceived by health professionals who have experience in recognising or responding to clinical deterioration, or in the management, administration or governance of RRSs. A written questionnaire containing 12 pre-determined factors was provided to participants. Participants were asked to rank the items from most to least important contributors to ward patient deterioration. The study took place during a session of the Australia and New Zealand Intensive Care Society Rapid Response Team conference. A final sample of 233 (83% response rate), returned the questionnaire. The sample comprised specialist ICU registered nurses with direct patient contact (64%), ICU consultant doctors (17%), ICU nurse managers (7%), hospital administrators (2%), ICU registrars (2%), quality coordinators (2%) and non-hospital staff (4%). The patient's presenting illness/main diagnosis was the highest ranked factor, followed by pre-existing co-morbidities, seniority of nursing ward staff, medical documentation, senior medical staff, and interdisciplinary communication. Almost two-thirds of participants ranked patient characteristics as the most important contributor to clinical deterioration.

Relapses represent one of the main problems of schizophrenia management. This article reviews the clinical factors associated with schizophrenia relapse. A research of the last 22 years of literature data was performed. Two-hundred nineteen studies have been included. Three main groups of factors are related to relapse: factors associated with pharmacological treatment, add-on psychotherapeutic treatments and general risk factors. Overall, the absence of a maintenance therapy and treatment with first generation antipsychotics has been associated with higher risk of relapse. Further, psychotherapy add-on, particularly with cognitive behaviour therapy and psycho-education for both patients and relatives, has shown a good efficacy for reducing the relapse rate. Among general risk factors, some could be modified, such as the duration of untreated psychosis or the substance misuse, while others could not be modified as male gender or low pre-morbid level of functioning. Several classes of risk factors have been proved to be relevant in the risk of relapse. Thus, a careful assessment of the risk factors here identified should be performed in daily clinical practice in order to individualise the relapse risk for each patient and to provide a targeted treatment in high-risk subjects.

Preditive clinical factors for epileptic seizures after ischemic stroke. Clinical features of 35 patients with ischemic stroke who developed epilepsy (Group 1) were compared with those of 35 patients with ischemic stroke without epilepsy (Group 2). The age of the patients did not differ between the groups. There were more men than women and more white than other races in both groups. Diabetes melitus, hypertension, transient ischemic attack, previous stroke, migraine, Chagas disease, cerebral embolism of cardiac origin and use of oral contraceptive did not differ between the groups. Smokers and alcohol users were more frequent in Group 1 (p < 0.05). Most patients of Group 1 presented with hemiparesis; none presented cerebellar or brainstem involvement. Perhaps strokes in smokers have some different aspects, that let them more epileptogenic than in non smokers.

To describe the clinical manifestations, cerebrospinal fluid (CSF) characteristics, imaging studies and prognostic factors of adverse clinical outcomes (ACO) among adults with herpes simplex virus (HSV) or varicella zoster virus (VZV) CNS infections. Retrospective review of adult patients with positive HSV or VZV polymerase chain reaction on CSF from an observational study of meningitis or encephalitis in Houston, TX (2004-2014), and New Orleans, LA (1999-2008). Ninety-eight adults patients were identified; 25 had encephalitis [20 (20.4 %) HSV, 5 (5.1 %) VZV], and 73 had meningitis [60 (61.1 %) HSV and 13 (13.3 %) VZV]. HSV and VZV had similar presentations except for nausea (P < 0.01) and rash (P < 0.001). The CSF profile did not differ between HSV and VZV infection. Abnormal neuroimaging findings were found in 11.6 % (10/86) brain CTs and 21.3 % (16/75) brain MRIs. The EEG was abnormal in 57.9 % (11/19). Sixteen patients (16.3 %) had an ACO (10 HSV encephalitis, 3 VZV encephalitis and 3 VZV meningitis). Intravenous acyclovir administered within 48 h was protective against an ACO [OR 0.19 (0.04-0.80), P = 0.02). However, on logistic regression only Charlson comorbidity score >1 and an encephalitis presentation were independently associated with an ACO. The treatment for HSV meningitis was variable, and all patients had a good clinical outcome. Alpha herpes CNS infections due to HSV and VZV infections have similar clinical and laboratory manifestations. ACO was observed more frequently in those patients with comorbidities and an encephalitis presentation.

Psychometric investigations of the Eating Disorder Examination-Questionnaire (EDE-Q) have generally not supported the original scale structure. The present study tested an alternative brief factor structure in two large Portuguese samples: (1) a non-clinical sample of N = 4117 female students and (2) a treatment-seeking sample of N = 609 patients diagnosed with eating disorders. Confirmatory factor analysis revealed a poor fit for the original EDE-Q structure in both the non-clinical and the clinical samples but revealed a good fit for the alternative 7-item 3-factor structure (dietary restraint, shape/weight overvaluation and body dissatisfaction). Factor loadings were invariant across samples and across the different specific eating disorder diagnoses in the clinical sample. These confirmatory factor analysis findings, which replicate findings from studies with diverse predominately overweight/obese samples, supported a modified 7-item, 3-factor structure for the EDE-Q. The reliable findings across different non-clinical and clinical eating disorder groups provide confidence regarding the potential utility of this brief version.

Perinatal period may pose a great challenge for the clinical management and treatment of psychiatric disorders in women. In fact, several mental illnesses can arise during pregnancy and/or following childbirth. Suicide has been considered a relatively rare event during the perinatal period. However, in some mental disorders (i.e., postpartum depression, bipolar disorder, postpartum psychosis, etc.) have been reported a higher risk of suicidal ideation, suicide attempt, or suicide. Therefore, a complete screening of mothers’ mental health should also take into account thoughts of suicide and thoughts about harming infants as well. Clinicians should carefully monitor and early identify related clinical manifestations, potential risk factors, and alarm symptoms related to suicide. The present paper aims at providing a focused review about epidemiological data, risk factors, and an overview about the main clinical correlates associated with the suicidal behavior during the pregnancy and postpartum period. Practical recommendations have been provided as well. PMID:27570512

The variability of demographic, social, genetic, and clinical factors might influence the time between the onset of symptoms and the diagnosis [diagnostic delay (DD)] of ankylosing spondylitis (AS) in different geographic areas. Different clinical manifestations in men and women affected by AS might indicate a possible role of gender in DD. The aim of the present study was to investigate the influence of demographic, social, genetic, and clinical factors on DD and the differences of DD between men and women related to the presence of different demographic, social, clinical, and genetic parameters in an Italian cohort of primary AS patients. A total of 135 Italian primary AS patients (45 female and 90 male, 27.9 ± 0.89 years old at onset) were studied. The DD, gender, education and work (manual or non-manual) levels, and type of first clinical presentation (inflammatory back pain, arthritis, enthesitis) at onset, family history of AS, and HLA B27 presence were analyzed. The DD (8.744 mean ±0.6869) was significantly higher in men (p = 0.0023), in axial presentation (p = 0.0021), and in manual work (even if with low significance, p = 0.047). The lower DD in women in comparison to that in men was likely related to higher education (p = 0.0045) and work (p = 0.0186) levels, peripheral involvement (p = 0.0009), and HLA B27 positivity (p = 0.0231). DD was higher in AS patients: male, employed in manual jobs, and with axial symptoms at onset. In men, DD seemed to be negatively influenced by lower level of education and work, axial clinical presentation, and HLA B27.

Clinical trials are frequently hindered by difficulties in recruiting eligible participants, increasing the timeline and limiting generalizability of results. In veterinary medicine, where proxy enrollment is required, no studies have detailed what factors influence owner participation in clinical trials involving cats. We aimed to investigate these factors through a survey of owners at first opinion practices. The survey was designed using feedback from a pilot study and input from clinical researchers. Owners were asked demographic questions and whether they would, would not, or were unsure about participating in a clinical trial with their cat. They then ranked the importance and influence of various factors on participation using a five-point Likert-type scale, and incentives from most to least encouraging. A total of 413 surveys were distributed to cat owners at four hospitals, two feline-only and two multi-species; 88.6% were completed. Data for importance and influence factors as well as incentive rankings were analyzed overall, and by hospital type, location and whether owners would consider participating. The most influential factors were trust in the organization, benefit to the cat and veterinarian recommendation. Importance and influence factors varied by willingness to participate. Ranked incentives were not significantly different across groups, with 'Free Services' ranked highest. This study provides a first look at what factors influence participation in clinical trials with cats. Given the importance placed in the recommendation of veterinarians, continued work is needed to determine veterinarian-related factors affecting clinical trial participation. The results provide guidance towards improved clinical trial design, promotion and education. © ISFM and AAFP 2014.

Negative Mood and Obsessive-Compulsive Related Clinical Constructs: An Examination of Underlying Factors

PubMed Central

Britton, Gary I.; Davey, Graham C. L.

2017-01-01

Emerging evidence suggests that many of the clinical constructs used to help understand and explain obsessive-compulsive (OC) symptoms, and negative mood, may be causally interrelated. One approach to understanding this interrelatedness is a motivational systems approach. This approach suggests that rather than considering clinical constructs and negative affect as separable entities, they are all features of an integrated threat management system, and as such are highly coordinated and interdependent. The aim of the present study was to examine if clinical constructs related to OC symptoms and negative mood are best treated as separable or, alternatively, if these clinical constructs and negative mood are best seen as indicators of an underlying superordinate variable, as would be predicted by a motivational systems approach. A sample of 370 student participants completed measures of mood and the clinical constructs of inflated responsibility, intolerance of uncertainty, not just right experiences, and checking stop rules. An exploratory factor analysis suggested two plausible factor structures, one where all construct items and negative mood items loaded onto one underlying superordinate variable, and a second structure comprising of five factors, where each item loaded onto a factor representative of what the item was originally intended to measure. A confirmatory factor analysis showed that the five factor model was preferential to the one factor model, suggesting the four constructs and negative mood are best conceptualized as separate variables. Given the predictions of a motivational systems approach were not supported in the current study, other possible explanations for the causal interrelatedness between clinical constructs and negative mood are discussed.

Nasopharyngeal carcinoma (NPC) is a common cancer in Malaysia. The clinical presentation in Sarawak has not been well documented. A retrospective review of 213 selected NPC cases was undertaken on the clinical records in Sarawak General Hospital, Sarawak, from June 1999 to June 2003. There were 116 patients in Kuching and 97 in Serian. There were twice as many males as females. The youngest patient was 16 and the oldest 88 years old with a mean age of 51 years. The four most common symptoms in order of frequencies were cervical lymphadenopathy, epistaxis, hearing loss and diplopia. 80.8% of the patients presented with cervical lymphadenopathy and about 85% of the patients presented in the advanced stages. Very small percentages of the patients were found to have single presenting symptoms of epistaxis (2.4%) and hearing loss (0.5%).

Catatonia is not a usual clinical presentation of subacute sclerosing panencephalitis (SSPE), especially in the initial stages of illness. However, there is only one reported case of SSPE presenting as catatonia among children. In this report, however, there were SSPE-specific changes on EEG and the catatonia failed to respond to lorazepam. We describe a case of SSPE in a child presenting as catatonia that presented with clinical features of catatonia and did not have typical EEG findings when assessed at first contact. He responded to lorazepam and EEG changes emerged during the course of follow-up. PMID:24891908

Failure to initiate or intensify therapy according to evidence-based guidelines is increasingly being acknowledged as a phenomenon that contributes to inadequate management of chronic conditions, and is referred to as clinical inertia. However, the number and complexity of factors associated with the clinical reasoning that underlies the decision-making processes in medicine calls for a critical examination of the consistency of the concept. Indeed, in the absence of information on and justification of treatment decisions that were made, clinical inertia may be only apparent, and actually reflect good clinical practice. This integrative review seeks to address the factors generally associated with clinical inaction, in order to better delineate the concept of true clinical inertia. PMID:24868181

The varied clinical presentations of major depressive disorder.

2007-01-01

DSM-IV major depressive disorder (MDD) is a clinical syndrome notable for heterogeneity of its clinical presentation, genetics, neurobiology, clinical course, and treatment responsiveness. In an attempt to make sense of this heterogeneity, clinicians and researchers have proposed a number of MDD "subtypes" based on differences in characteristic symptoms (e.g., atypical, melancholic, psychotic), onset (e.g., early vs. late, post-partum, seasonal), course of illness (e.g., single vs. recurrent, chronic, double), and severity. This article provides a brief review of the status of several of the most common subtypes in terms of their clinical features, biological correlates, course of illness, and treatment implications.

HIV/AIDS has significantly affected health care practices. The need for high adherence and regular clinic visits places pressure on health care providers and patients. Poor quality of care has been described in many contexts, but some clinics have achieved excellent treatment results. Using a success case approach, this study aimed to understand factors which contribute to successful care at a South African pediatric HIV/AIDS clinic with documented high patient adherence and follow-up rates. Data included over 50 hours of ethnographic observations and interviews with a total of 35 clinic staff and caregivers. Thematic analysis highlighted strong congruence between caregiver and staff perceptions. Factors which seemed to contribute to successful care included organizational routines, staff-patient relationships, communication, teamwork, leadership, job commitment, caregivers' negative experiences at other clinics, and faith in the "life-saving" care at this clinic. Results suggest the need for all factors to be present in order to promote quality of care. Recommendations for other clinic settings are discussed.

This study examines the influence of six patient characteristics (age, race, socioeconomic status, comorbidities, mobility and presentational style) and two physician characteristics (medical specialty and years of clinical experience) on physicians' clinical decision making behaviour in the evaluation treatment of an unknown and known breast cancer. Physicians' variability and certainty associated with diagnostic and treatment behaviour were also examined. Separate analyses explored the influence of these non-medical factors on physicians' cognitive processes. Using a fractional factorial design, 128 practising physicians were shown two videotaped scenarios and asked about possible diagnoses and medical recommendations. Results showed that physicians displayed considerable variability in response to several patient-based factors. Physician characteristics also emerged as important predictors of clinical behaviour, thus confirming the complexity of the medical decision-making process.

Developing a "clinical presentation" curriculum at the University of Calgary.

Mandin, H; Harasym, P; Eagle, C; Watanabe, M

1995-03-01

Currently, medical curricula are structured according to disciplines, body systems, or clinical problems. Beginning in 1988, the faculty of the University of Calgary Faculty of Medicine (U of C) carefully evaluated the advantages and disadvantages of each of these models in seeking to revise their school's curriculum. However, all three models fell short of a curricular structure based on current knowledge and principles of adult learning, clinical problem solving, community demands, and curriculum management. By 1991, the U of C had formulated a strategic plan for a revised curriculum structure based on the way patients present to physicians, and implementation of this plan has begun. In creating the new curriculum, 120 clinical presentations (e.g., "loss of consciousness/syncope") were defined and each was assigned to an individual or small group of faculty for development based on faculty expertise and interest. Terminal objectives (i.e., "what to do") were defined for each presentation to describe the appropriate clinical behaviors of a graduating physician. Experts developed schemes that outlined how they differentiated one cause (i.e., disease category) from another. The underlying enabling objectives (i.e., knowledge, skills, and attitudes) for reaching the terminal objectives for each clinical presentation were assigned as departmental responsibilities. A new administrative structure evolved in which there is a partnership between a centralized multidisciplinary curriculum committee and the departments. This new competency-based, clinical presentation curriculum is expected to significantly enhance students' development of clinical problem-solving skills and affirms the premise that prudent, continuous updating is essential for improving the quality of medical education.

Hepatitis C virus (HCV) has become a significant source of morbidity and mortality in HIV-infected patients. However, little is known about the clinical presentation and course of acute HCV infection in this population. This study reports the outcomes of acute HCV infection in 9 HIV-infected men. Sex with men was the only reported risk factor for HCV infection in 6 of the subjects. Clinical presentation of acute HCV ranged from incidentally discovered elevated transaminases to severe liver dysfunction requiring hospitalization. At the time of HCV diagnosis, 8 of 9 patients had CD4+ counts >250 cells/mm(3), and 6 had HIV viral loads of < or =5000 copies/mL. Eight patients were receiving antiretroviral therapy. Outcome of these acute HCV infections varied. Five patients experienced virologic clearance, 2 in whom virus cleared spontaneously and 3 who were treated with pegylated interferon and ribavirin. Four patients developed chronic infection, one of whom had a relapse during HCV treatment and 3 of whom were untreated. All 4 patients to whom HCV therapy was administered experienced significant anemia or neutropenia, necessitating dose reduction or support with growth factors. Prompt recognition of acute HCV infection may minimize antiretroviral treatment interruption and will allow early treatment, which may improve virologic clearance. Unexplained transaminase elevations in HIV-infected patients, including men who have sex with men, should trigger an evaluation for acute HCV infection.

The aim of this study was to determine the clinical presentation and severity of ulcerative colitis (UC) in Pakistani adult patients. An observational study. Data were obtained by reviewing the medical records of patients who visited a gastroenterology clinic between 2008 and 2012. There were 54 patients diagnosed as UC. The male to female ratio was 1:1. Mean age at diagnosis of UC was 38.7 ± 11.8 years (median 36.5, range 18-64). The predominant presenting symptoms were mucus diarrhea in 49 (90.7%), gross blood in stools in 42 (77.8%), abdominal pain or cramps in 40 (74.1%) and weight loss in 15 (27.7%). Left-sided colitis was present in 23 (42.6%), pancolitis in 15 (27.8%), extensive colitis in 11 (20.4%), and proctitis in five (9.2%). The severity of UC as judged by the Mayo scoring system showed that 68.5% were suffering from moderate to severe disease while 31.5% had mild disease. The extra-intestinal manifestation were found only in seven patients; arthritis in five patients and anterior uveitis in two patients. The arthritis was unilateral and the sites were knee joint in three patients and sacroiliac joint in two patients. Ulcerative colitis presents in our adult patients may present at any age with no gender preponderance. The disease severity is moderate to severe in the majority of patients and more than half of them have left-sided colitis or pancolitis at the time of presentation. Extraintestinal manifestations were not common. Qureshi M, Abbas Z. Clinical Presentation of Ulcerative Colitis in Pakistani Adults. Euroasian J Hepato-Gastroenterol 2015;5(2):127-130.

There is limited information on the extent and clinical importance of the delay in hospital presentation of acute pulmonary thromboembolism (PTE). The aim of this study was to investigate the delay in hospital presentation of PTE and its association with clinical and imaging findings in PTE. This prospective study was conducted on patients admitted to our hospital with a diagnosis of acute PTE between September 2007 and September 2011. Relationships between delay in hospital presentation and clinical findings, risk factors, imaging findings, and in-hospital mortality were analyzed. Of the 195 patients enrolled, 84 (43.1%) patients presented 3 days after the onset of symptoms. Patients with chest pain, history of immobility for more than 3 days, recent surgery, and estrogen use had significantly less delayed presentation. Right ventricular dysfunction was significantly more frequent in patients with delayed presentation (odds ratio [OR] = 2.38; 95% confidence interval [CI] 1.27-4.44; p = 0.006); however, no relationship was found between delay in presentation and pulmonary computed tomographic angiography or color Doppler sonography findings. Patients with delayed presentation were at higher risk of in-hospital mortality (OR = 4.32; 95% CI 1.12-16.49; p = 0.021). Our study showed that a significant portion of patients with acute PTE had delayed presentation. Also, patients with delayed presentation had worse echocardiographic findings and higher in-hospital mortality. Copyright © 2014 Elsevier Inc. All rights reserved.

Abstract Morning reports offer opportunities for intensive work-based learning. In this controlled study, we measured learning processes and outcomes with the report of paediatric emergency room patients. Twelve specialists and 12 residents were randomised into four groups and discussed the same two paediatric cases. The groups differed in their presentation modality (verbal only vs. verbal + text) and the use of buzz groups (with vs. without). The verbal interactions were analysed for clinical reasoning processes. Perceptions of learning and judgment of learning were reported in a questionnaire. Diagnostic accuracy was assessed by a 20-item multiple-choice test. Combined bimodal presentation and buzz groups increased the odds ratio of clinical reasoning to occur in the discussion of cases by a factor of 1.90 (p = 0.013), indicating superior reasoning for buzz groups working with bimodal materials. For specialists, a positive effect of bimodal presentation was found on perceptions of learning (p < 0.05), and for residents, a positive effect of buzz groups was found on judgment of learning (p < 0.005). A positive effect of bimodal presentation on diagnostic accuracy was noted in the specialists (p < 0.05). Combined bimodal presentation and buzz group discussion of emergency cases improves clinicians' clinical reasoning and learning.

Acetaminophen (APAP) is the most common cause of acute liver failure (ALF) in the west. It is unknown if APAP overdose in combination with diphenhydramine or opioids confers a different clinical presentation or prognosis. Study objectives were to compare (1) baseline patient characteristics; (2) initial clinical presentation; and (3) clinical outcomes among patients with ALF due to APAP alone or in combination with diphenhydramine or opioids. We analyzed 666 cases of APAP-related liver failure using the Acute Liver Failure Study Group database from 1998 to 2012. The database contains detailed demographic, laboratory, and clinical outcome data, including hemodialysis, transplantation, and death and in-hospital complications such as arrhythmia and infection. The final sample included 666 patients with APAP liver injury. A total 30.3% of patients were overdosed with APAP alone, 14.1% with APAP/diphenhydramine, and 56.6% with APAP/opioids. Patients taking APAP with opioids were older, had more comorbidities, and were more likely to have unintentional overdose (all P<0.0001). On presentation, 58% in the APAP/opioid group had advanced encephalopathy as compared with 43% with APAP alone (P=0.001) The APAP/diphenhydramine group presented with the highest serum aminotransferase levels, no differences in laboratory values were noted at 3 days postenrollment. No significant differences were observed in clinical outcomes among the groups. Most patients with APAP-induced ALF were taking APAP combination products. There were significant differences in patient characteristics and clinical presentation based on the type of product ingested, however, there were no differences noted in delayed hepatotoxicity or clinical outcomes.

Factors Associated with Veterinary Clinical Faculty Attrition.

PubMed

Furr, Martin

Faculty attrition and recruitment for veterinary clinical faculty positions have been reported as significant problems in veterinary medical education. To investigate the factors that may be important in veterinary clinical faculty retention, the perceptions and views of veterinary clinical academic faculty were determined using a web-distributed electronic survey. Responses were dichotomized by whether the respondent had or had not left an academic position and were analyzed for their association with faculty attrition. A total of 1,226 responses were recorded, and results demonstrated that factors other than compensation were associated with veterinary clinical faculty attrition, including departmental culture, work-life balance, and recognition and support of clinical medicine by the administration. Forty-four percent of respondents who had held a faculty appointment reported leaving academia either voluntarily or for non-voluntary reasons such as failure to achieve tenure, retirement, or having their position closed. Attention to correcting deficiencies in workplace culture and professional rewards could be a beneficial means by which to decrease the faculty attrition rates currently observed in clinical academic veterinary medicine.

To specify psychopathological features and dynamics of depression developed at the stage of broad clinical presentations of anorexia nervosa (AN) in adolescent patients. Authors studied 61 young women, aged from 14 to 18 years, mean age 16.6 ± .9 years. Depressive states manifested during the first year of AN in all patients. Two variants of depressive episodes were described. The first variant was characterized by asthenic/depressive, somatic and autonomic presentations, with the leading role of exogenous/organic and somatogenic factors. In the second variant, affective disorders were characterized by the anxiety affect concomitant with adynamia, dysphoria and melancholia that most probably may be caused by endogenous constitutional/biological factors. The follow-up data (0,5-6 years) indicated that most of the patients with the second variant of depressive episodes had recurrent depressive states. During the course of disease, eating disorders acquired an atypical character and gradually decreased while the affective pathology became dominating. Depressive symptomatology in AN patients of pubertal age corresponded to main mechanisms of development of the clinical picture and dynamics of adolescent depression as atypical depressive triad, predominance of anxiety and asthenic/adynamic affect, a trend towards protracted course and substantial frequency of dysmorphophobic symptoms and over-valued ideas.

Background Cardiac amyloidosis is a fatal disease whose prognosis and treatment rely on identification of the amyloid type. In our aging population transthyretin amyloidosis (ATTRwt) is common and must be differentiated from other amyloid types. We report the clinical presentation, natural history, and prognostic features of ATTRwt compared with cardiac‐isolated AL amyloidosis and calculate the probability of disease diagnosis of ATTRwt from baseline factors. Methods and Results All patients with biopsy‐proven ATTRwt (102 cases) and isolated cardiac AL (36 cases) seen from 2002 to 2011 at the UK National Amyloidosis Center were included. Median survival from the onset of symptoms was 6.07 years in the ATTRwt group and 1.7 years in the AL group. Positive troponin, a pacemaker, and increasing New York Heart Association (NYHA) class were associated with worse survival in ATTRwt patients on univariate analysis. All patients with isolated cardiac AL and 24.1% of patients with ATTRwt had evidence of a plasma cell dyscrasia. Older age and lower N‐terminal pro‐B‐type natriuretic peptide (NT pro‐BNP) were factors significantly associated with ATTRwt. Patients aged 70 years and younger with an NT pro‐BNP <183 pmol/L were more likely to have ATTRwt, as were patients older than 70 years with an NT pro‐BNP <1420 pmol/L. Conclusions Factors at baseline associated with a worse outcome in ATTRwt are positive troponin T, a pacemaker, and NYHA class IV symptoms. The age of the patient at diagnosis and NT pro‐BNP level can aid in distinguishing ATTRwt from AL amyloidosis. PMID:23608605

Context specificity and the impact that contextual factors have on the complex process of clinical reasoning is poorly understood. Using situated cognition as the theoretical framework, our aim was to evaluate the verbalized clinical reasoning processes of resident physicians in order to describe what impact the presence of contextual factors have on their clinical reasoning. Participants viewed three video recorded clinical encounters portraying straightforward diagnoses in internal medicine with select patient contextual factors modified. After watching each video recording, participants completed a think-aloud protocol. Transcripts from the think-aloud protocols were analyzed using a constant comparative approach. After iterative coding, utterances were analyzed for emergent themes with utterances grouped into categories, themes and subthemes. Ten residents participated in the study with saturation reached during analysis. Participants universally acknowledged the presence of contextual factors in the video recordings. Four categories emerged as a consequence of the contextual factors: (1) emotional reactions (2) behavioral inferences (3) optimizing the doctor patient relationship and (4) difficulty with closure of the clinical encounter. The presence of contextual factors may impact clinical reasoning performance in resident physicians. When confronted with the presence of contextual factors in a clinical scenario, residents experienced difficulty with closure of the encounter, exhibited as diagnostic uncertainty. This finding raises important questions about the relationship between contextual factors and clinical reasoning activities and how this relationship might influence the cost effectiveness of care. This study also provides insight into how the phenomena of context specificity may be explained using situated cognition theory.

One of the most influential factors in science and medicine has been the development of placebo-controlled clinical trials. However, recruitment of patients for clinical trials is sometimes a major problem in clinical research. Successful patient recruitment may be enhanced with a clear understanding of the motivating factors that determine a patient's decision to enter a study. We have developed the Patients' Expectations, Attitudes and Knowledge (PEAK) Program consisting of questionnaires designed to study the factors motivating patients to enter a clinical trial, as well as capturing the experiences of research participants. A total of 247 female patients with dyspepsia (mean age: 43.9; range: 18.0-78.0 years) who entered either of two prospective double-blind, randomized, placebo-controlled multicenter trials in the USA completed PEAK Entry questionnaires during the first study visit. Based on their responses, the top three factors motivating patients to join the clinical trial were: interest in receiving investigational treatment with average score (AS) of 4.33 +/- 0.08 (M +/- SEM) on a 5-point scale, possibility of getting skilled professional care (AS = 4.07 +/- 0.09), and altruism expressed as an intention to help develop a new drug for the sake of other people (AS = 3.89 +/- 0.09). Age, ethnicity, and educational status significantly affected motivational factors of patients. These results indicate that recruitment can be enhanced by targeting these motivations in physician/patient communications, informed consent process and advertising for study participants.

[Chronic daily headache: clinical presentation].

PubMed

Chronic daily headache (CDH) represents a group of any headache disorder that occurs on a daily or near daily basis, for longer than 6 months. Even though it is a common problem, it is not a well defined disorder, resulting in controversies regarding its identification, description and approach. Three hundred patients, 232 women and 68 men, ages 16 to 86 (mean 38 years old for the women and 42 for the men), attending a headache center and fulfilling the proposed criteria for CDH (Silberstein et al.) and presenting headache 28 days per month were retrospectively studied. The clinical features allowed the primary headache diagnosis, before the transformation into daily presentation as: transformed migraine (TM ) in 271 patients (90,3%), chronic tension-type headache (CTTH) in 26 patients (8,7%) and new daily persistent headache (NDPH) in 3 patients (1%). Among the TM patients, the most observed presentation was pressure or tightening, bilateral fronto-temporal, moderate non-continuous headache, with a progressive onset. The association with nausea and phonophobia was demonstrated in 60% and 32% of the patients respectively. The association with photophobia and sleep disturbances, as well as the occurrence of intermittent headache attacks, was different among male and female patients. With regard to the CTTH patients, pressure or tightening, bilateral fronto-temporal, moderate non-continuous headache, with sleep disturbances and no associated symptoms, was the predominant presentation.

Growth factors and chronic wound healing: past, present, and future.

PubMed

Goldman, Robert

2004-01-01

Growth substances (cytokines and growth factors) are soluble signaling proteins affecting the process of normal wound healing. Cytokines govern the inflammatory phase that clears cellular and extracellular matrix debris. Wound repair is controlled by growth factors (platelet-derived growth factor [PDGF], keratinocyte growth factor, and transforming growth factor beta). Endogenous growth factors communicate across the dermal-epidermal interface. PDGF is important for most phases of wound healing. Becaplermin (PDGF-BB), the only growth factor approved by the Food and Drug Administration, requires daily application for neuropathic wound healing. Gene therapy is under development for more efficient growth factor delivery; a single application will induce constitutive growth factor expression for weeks. Based on dramatic preclinical animal studies, a phase 1 clinical trial planned on a PDGF genetic construct appears promising.

Clinical linguistics: its past, present and future.

Perkins, Michael R

2011-11-01

Historiography is a growing area of research within the discipline of linguistics, but so far the subfield of clinical linguistics has received virtually no systematic attention. This article attempts to rectify this by tracing the development of the discipline from its pre-scientific days up to the present time. As part of this, I include the results of a survey of articles published in Clinical Linguistics & Phonetics between 1987 and 2008 which shows, for example, a consistent primary focus on phonetics and phonology at the expense of grammar, semantics and pragmatics. I also trace the gradual broadening of the discipline from its roots in structural linguistics to its current reciprocal relationship with speech and language pathology and a range of other academic disciplines. Finally, I consider the scope of clinical linguistic research in 2011 and assess how the discipline seems likely develop in the future.

Cancer, Warts, or Asymptomatic Infections: Clinical Presentation Matches Codon Usage Preferences in Human Papillomaviruses

Viruses rely completely on the hosts’ machinery for translation of viral transcripts. However, for most viruses infecting humans, codon usage preferences (CUPrefs) do not match those of the host. Human papillomaviruses (HPVs) are a showcase to tackle this paradox: they present a large genotypic diversity and a broad range of phenotypic presentations, from asymptomatic infections to productive lesions and cancer. By applying phylogenetic inference and dimensionality reduction methods, we demonstrate first that genes in HPVs are poorly adapted to the average human CUPrefs, the only exception being capsid genes in viruses causing productive lesions. Phylogenetic relationships between HPVs explained only a small proportion of CUPrefs variation. Instead, the most important explanatory factor for viral CUPrefs was infection phenotype, as orthologous genes in viruses with similar clinical presentation displayed similar CUPrefs. Moreover, viral genes with similar spatiotemporal expression patterns also showed similar CUPrefs. Our results suggest that CUPrefs in HPVs reflect either variations in the mutation bias or differential selection pressures depending on the clinical presentation and expression timing. We propose that poor viral CUPrefs may be central to a trade-off between strong viral gene expression and the potential for eliciting protective immune response. PMID:26139833

Clinical presentation of bare metal stent in-stent restenosis (ISR) in patients undergoing target lesion revascularization is well characterized and negatively affects on outcomes, whereas the presentation and outcomes of first- and second-generation drug-eluting stents (DESs) remains under-reported. The study included 909 patients (1077 ISR lesions) distributed as follows: bare metal stent (n=388), first-generation DES (n=425), and second-generation DES (n=96), categorized into acute coronary syndrome (ACS) or non-ACS presentation mode at the time of first target lesion revascularization. ACS was further classified as myocardial infarction (MI) and unstable angina. For bare metal stent, first-generation DES and second-generation DES, ACS was the clinical presentation in 67.8%, 71.0%, and 66.7% of patients, respectively (P=0.470), whereas MI occurred in 10.6%, 10.1%, and 5.2% of patients, respectively (P=0.273). The correlates for MI as ISR presentation were current smokers (odds ratio, 3.02; 95% confidence interval [CI], 1.78-5.13; P<0.001), and chronic renal failure (odds ratio, 2.73; 95% CI, 1.60-4.70; P<0.001), with a protective trend for the second-generation DES ISR (odds ratio, 0.35; 95% CI, 0.12-1.03; P=0.060). ACS presentations had an independent effect on major adverse cardiac events (death, MI, and re-target lesion revascularization) at 6 months (MI versus non-ACS: adjusted hazard ratio, 4.06; 95% CI, 1.84-8.94; P<0.001; unstable angina versus non-ACS: adjusted hazard ratio, 1.98; 95% CI, 1.01-3.87; P=0.046). ISR clinical presentation is similar irrespective of stent type. MI as ISR presentation seems to be associated with patient and not device-related factors. ACS as ISR presentation has an independent effect on major adverse cardiac events, suggesting that ISR remains a hazard and should be minimized. © 2014 American Heart Association, Inc.

Staphylococcus aureus bacteremia is a life-threatening condition that may lead to metastatic infection, including prosthetic joint infection. To assess clinical factors associated with hematogenous prosthetic joint infection, we retrospectively reviewed all patients with a joint arthroplasty in place at the time of a first episode of S. aureus bacteremia over a 5-year period at our institution. Patients with postsurgical prosthetic joint infection without hematogenous prosthetic joint infection were excluded. There were 85 patients (143 arthroplasties) with either no prosthetic joint infection (n = 50; 58.8%) or hematogenous prosthetic joint infection in at least one arthroplasty (n = 35; 41.2%). The odds of hematogenous prosthetic joint infection was significantly increased among patients with community-acquired S. aureus bacteremia (odds ratio [OR] 18.07; 95% confidence interval [CI] 2.64-infinity; P = .001), as compared with nosocomial S. aureus bacteremia, in which there were no patients with hematogenous prosthetic joint infection. After adjusting for S. aureus bacteremia classification, the presence of ≥3 joint arthroplasties in place was associated with a nearly ninefold increased odds of hematogenous prosthetic joint infection as compared with those with 1-2 joint arthroplasties in place (OR 8.55; 95% CI 1.44-95.71; P = .012). All but one joint with prosthetic joint infection demonstrated at least one clinical feature suggestive of infection. There were 4 additional S. aureus prosthetic joint infections diagnosed during a median of 3.4 years of follow-up post hospitalization for S. aureus bacteremia. Prosthetic joint infection is frequent in patients with existing arthroplasties and concomitant S. aureus bacteremia, particularly with community-acquired S. aureus bacteremia and multiple prostheses. In contrast, occult S. aureus prosthetic joint infection without clinical features suggestive of prosthetic joint infection at the time of S. aureus bacteremia

The Clinical Presentation of Oral Potentially Malignant Disorders.

2016-02-01

Early detection of oral cancer improves survival rates significantly, however, the incidence of oral cancer has continued to rise in the UK - between 2002-2012, it increased by more than 30%. There is currently no national screening programme for oral cancer, so undertaking a full examination of the oral mucosa during routine dental appointments is vital. Although strong evidence is still lacking, oral cancer is thought to be preceded by oral potential malignant disorders (OPMDs) or oral precancerous diseases. These mainly present as white/red lesions within the mouth and their clinical appearance can be challenging to diagnose accurately, which can lead to them being misdiagnosed as negligible problems. Dentists must keep up to date with OPMDs detection and ensure they are capable of correctly recognising lesions that carry a potential risk. This paper aims to provide a brief overview on OPMDs, highlighting potentially malignant disorders as they may present to the practitioner, showing their typical clinical appearance, and suggesting differential diagnosis and clinical management in dental practice.

Clinical factors affecting pathological fracture and healing of unicameral bone cysts

PubMed Central

2014-01-01

Background Unicameral bone cyst (UBC) is the most common benign lytic bone lesion seen in children. The aim of this study is to investigate clinical factors affecting pathological fracture and healing of UBC. Methods We retrospectively reviewed 155 UBC patients who consulted Nagoya musculoskeletal oncology group hospitals in Japan. Sixty of the 155 patients had pathological fracture at presentation. Of 141 patients with follow-up periods exceeding 6 months, 77 were followed conservatively and 64 treated by surgery. Results The fracture risk was significantly higher in the humerus than other bones. In multivariate analysis, ballooning of bone, cyst in long bone, male sex, thin cortical thickness and multilocular cyst were significant adverse prognostic factors for pathological fractures at presentation. The healing rates were 30% and 83% with observation and surgery, respectively. Multivariate analysis revealed that fracture at presentation and history of biopsy were good prognostic factors for healing of UBC in patients under observation. Conclusion The present results suggest that mechanical disruption of UBC such as fracture and biopsy promotes healing, and thus watchful waiting is indicated in these patients, whereas patients with poor prognostic factors for fractures should be considered for surgery.

The relationship of postnatal (postpartum) depression (PND) to episodes of depression occurring at other times is not well understood. Despite a number of studies of clinical presentation, there is little consistency in the literature. We have undertaken within- and between-individual comparisons of the clinical presentation of postnatal (PN) and non-postnatal (NPN) depressive episodes in women with recurrent depression. In a sample of well-characterized, parous women meeting DSM-IV and ICD-10 criteria for recurrent major depressive disorder, the clinical presentation of episodes of major depression with onset within 4 weeks of giving birth (PND group, n=50) were compared with (i) the non-postnatal episodes of women with PND, and (ii) episodes of major depression in parous women who had not experienced episodes of mood disorder in relation to childbirth (NPND group, n=132). In addition, the non-postnatal episodes of the PND group of women were compared with the depressive episodes of the NPND group. The small number of differences found between PN and NPN depressive episodes, such as reduced early morning wakening in postnatal episodes, are likely to be explicable by the context of having a new baby rather than by any difference in the nature of the underlying depression. The results do not point to substantial differences in clinical presentation between episodes of major depression occurring in relation to childbirth and at other times. Other avenues of research are therefore required to demonstrate a specific relationship between childbirth and depression.

This study aimed to identify and assess the factors that influence communication quality between clinical pharmacists and patients using a structural equation model based on the predisposing, reinforcing, and enabling constructs in educational/environmental diagnosis and evaluation-policy, regulatory, and organizational constructs in educational and ecological development model to identify the most effective path to increase their communication quality. A survey was conducted at 253 Class-A tertiary hospitals in China from March to December 2016. During on-site observations, verbal communications between clinical pharmacists ( n = 752) and patients were audio recorded, and communication quality was rated by an expert panel on an 8-item Quality of Communication Rating Scale. Clinical pharmacists completed questionnaires that examined the predisposing, enabling, and reinforcing factors that influenced communication quality. Finally, AMOS was employed to examine the relationships between the three factors and communication quality. The results indicated that all three factors positively affected communication quality, with correlation coefficients of .26, .13, and .17, respectively. The most influential predisposing factor was attitude (.77), the most influential enabling factors were self-efficacy (.71) and confidence (.72), and the most influential reinforcing factor was rewards (.74). The findings suggest that pharmacists' attitudes toward, perceived knowledge of, and skill and confidence in communication, and the rewards offered by pharmacy management are the most influential factors that influence communication quality.

Psychosocial and clinical risk factor profiles in managers.

2000-06-01

Over the past 10 years the IAS Foundation has performed more than 15,000 PREVENT check-ups on managers. In addition to a comprehensive clinical program of preventive examinations, the main emphasis is placed on extensive counseling. This counseling centres not only on personal behaviour patterns affecting the individual's health, but also on the psychomental capabilities of the patient within the context of the psychosocial stresses in managerial positions. Three cross-sectional studies examined: (1) the major cardiovascular risk factors (n = 974), (2) the psychosocial structure (n = 2,800) and (3) the relationships between clinical risk factors and psychological structural features (n = 200). According to expectations, managers showed somewhat lower cardiovascular risk levels than did other professional groups. However, nearly 70% of them reported various unspecific, psychovegetative complaints. Managers were subdivided into four psychological types, each representing roughly one quarter of the series: Type 1: anxiety, tension (20.5%); Type 2: repression, lack of self-control (22.2%); Type 3: challenge, ambition, self-control (27.6%); Type 4: healthy living, with self-control (29.7%). Type 3 resembles most closely classic type A behaviour and is seen in a good quarter of the overall cohort. This may indicate that not only people showing type A behaviour are predestined to occupy managerial positions, but that people with a type B structure also take up managerial positions. It is, however, in particular the type B behavioural patterns that are also associated with increased psychovegetative complaints. The relationships between psychosocial structural variables and clinical risk factors such as hypercholesteremia and high blood pressure are not very strong. Occupational health measures in organisations should also be established for managers, as they present an important employee group within the enterprise. In addition to examining them for cardiovascular risks

Soft-tissue infections vary widely in their nature and severity. A clear approach to the management must allow their rapid identification and treatment as they can be life-threatening. Clinical presentation of soft-tissue infections and its management. A prospective study based on 100 patients presenting with soft-tissue infections was done. All the cases of soft-tissue infections were considered irrespective of age, sex, etiological factors, or systemic disorders. The findings were evaluated regarding the pattern of soft-tissue infections in relation to age and sex, clinical presentation, complications, duration of hospital stay, management, and mortality. The most commonly involved age group was in the range of 41-60 years with male predominance. Abscess formation (45%) was the most common clinical presentation. Type 2 diabetes mellitus was the most common associated comorbid condition. Staphylococcus aureus was the most common culture isolate obtained. The most common complication seen was renal failure. Patients with surgical site infections had maximum duration of stay in the hospital. About 94% of the cases of soft-tissue infections were managed surgically. Mortality was mostly encountered in the cases of complications of cellulitis. Skin and soft-tissue infections are among the most common infections encountered by the emergency physicians. Ignorance, reluctance to treatment, economic constraints, and illiteracy delay the early detection and the initiation of proper treatment. Adequate and timely surgical intervention in most of the cases is of utmost importance to prevent the complications and reduce the mortality.

Chronic traumatic encephalopathy (CTE) is a neuropathologically defined disease reportedly linked to a history of repetitive brain trauma. As such, retired collision sport athletes are likely at heightened risk for developing CTE. Researchers have described distinct pathological features of CTE as well a wide range of clinical symptom presentations, recently termed traumatic encephalopathy syndrome (TES). These clinical symptoms are highly variable, non-specific to individuals described as having CTE pathology in case reports, and are often associated with many other factors. This review describes the cognitive, emotional, and behavioral changes associated with 1) developmental and demographic factors, 2) neurodevelopmental disorders, 3) normal aging, 4) adjusting to retirement, 5) drug and alcohol abuse, 6) surgeries and anesthesia, and 7) sleep difficulties, as well as the relationship between these factors and risk for developing dementia-related neurodegenerative disease. We discuss why some professional athletes may be particularly susceptible to many of these effects and the importance of choosing appropriate controls groups when designing research protocols. We conclude that these factors should be considered as modifiers predominantly of the clinical outcomes associated with repetitive brain trauma within a broader biopsychosocial framework when interpreting and attributing symptom development, though also note potential effects on neuropathological outcomes. Importantly, this could have significant treatment implications for improving quality of life. PMID:27561662

We developed a multimedia presentation platform that allows retrieving data from any digital and analog modalities and to prepare a script of a clinical presentation in an XML format. This system was designed for cardiac multi-disciplinary conferences involving different cardiology specialists as well as cardiovascular surgeons. A typical presentation requires preparation of summary reports of data obtained from the different investigations and imaging techniques. An XML-based scripting methodology was developed to allow for preparation of clinical presentations. The image display program uses the generated script for the sequential presentation of different images that are displayed on pre-determined presentation settings. The ability to prepare and present clinical conferences electronically is more efficient and less time consuming than conventional settings using analog and digital documents, films and videotapes. The script of a given presentation can further be saved as part of the patient record for subsequent review of the documents and images that supported a given medical or therapeutic decision. This also constitutes a perfect documentation method for surgeons and physicians responsible of therapeutic procedures that were decided upon during the clinical conference. It allows them to review the relevant data that supported a given therapeutic decision.

The oral presentation of the clinical long case is commonly an implied knowledge. The challenge of the presentation is compounded by the examiners' preferences and sometimes inadequate understanding of what should be assessed. To highlight the different opinions and misconceptions of trainers as the basis for improving our understanding and assessment of oral presentation of the clinical long case. Questionnaire was administered during the West African College of Surgeons fellowship clinical examinations and at their workplaces. Eligibility criteria included being a surgeon, a trainer and responding to all questions. Of the 72 questionnaires that were returned, 36(50%) were eligible for the analysis. The 36 respondents were from 14 centers in Nigeria and Ghana. Fifty-two percent were examiners at the postgraduate medical colleges and 9(25%) were professors. Eight(22.2%) indicated they were unaware of the separate methods of oral presentation for different occasions while 21( 58.3%) respondents were aware that candidate used the "5Cs" method and the traditional compartmentalized method in long case oral presentation. Eleven(30.6%) wanted postgraduates to present differently on a much higher level than undergraduate despite not encountering same in literature and 21(58.3%) indicated it was an unwritten rule. Seventeen (47.2%) had not previously encountered the "5Cs" of history of presenting complaint in literature also 17(47.2%) teach it to medical students and their junior residents. This study has shown that examiners definitely have varying opinions on what form the oral presentation of the clinical long case at surgery fellowship/professional examination should be and it translates to their expectations of the residents or clinical students. This highlights the need for standardization and consensus of what is expected at a formal oral presentation during the clinical long case examination in order to avoid subjectivity and bias.

Conceptual models for assessing and treating sport-related concussion (SRC) have evolved from a homogenous approach to include different clinical profiles that reflect the heterogeneous nature of this injury and its effects. There are six identified clinical profiles, or subtypes from SRC, and one such clinical profile is the anxiety/mood profile. Athletes with this profile experience predominant emotional disturbance and anxiety following SRC. The purpose of this targeted review was to present an overview of the empirical evidence to support factors contributing to the anxiety/mood profile, along with methods of evaluation and treatment of this clinical profile following SRC. We discuss the potential underlying mechanisms and risk factors for this clinical profile, describe comprehensive assessments to evaluate concussed athletes with an anxiety/mood clinical profile, and explore behavioral and other interventions for treating these athletes. Although there is limited, but growing empirical evidence for the anxiety/mood clinical profile following SRC, understanding this clinical profile is germane for clinicians who are treating athletes with emotional sequelae after SRC.

Hepatocellular carcinoma (HCC) is a dismal tumor with a high incidence, prevalence and poor prognosis and survival. Management of HCC necessitates multidisciplinary clinics due to the wide heterogeneity in its presentation, different therapeutic options, variable biologic behavior and background presence of chronic liver disease. We studied the different prognostic factors that affected survival of our patients to improve future HCC management and patient survival. This study is performed in a specialized multidisciplinary clinic for HCC in Kasr El Eini Hospital, Cairo University, Egypt. We retrospectively analyzed the different patient and tumor characteristics and the primary mode of management applied to our patients. Further analysis was performed using univariate and multivariate statistics. During the period February 2009 till February 2013, 290 HCC patients presented to our multidisciplinary clinic. They were predominantly males and the mean age was 56.5 ± 7.7 years. All cases developed HCC on top of cirrhosis that was mainly due to HCV (71%). Most of our patients were Child-Pugh A (50%) or B (36.9%) and commonly presented with small single lesions. Transarterial chemoembolization was the most common line of treatment used (32.4%). The overall survival was 79.9% at 6 months, 54.5% at 1 year and 22.4% at 2 years. Serum bilirubin, site of the tumor and type of treatment were the significant independent prognostic factors for survival. Our main prognostic variables are the bilirubin level, the bilobar hepatic affection and the application of specific treatment (either curative or palliative). Multidisciplinary clinics enhance better HCC management.

Introduction Although nursing students spend a large part of their learning period in the clinical environment, clinical learning has not been perceived by its nature yet. To develop an instrument to measure effective factors on clinical learning in nursing students. Methods This is a mixed methods study performed in 2 steps. First, the researchers defined “clinical learning” in nursing students through qualitative content analysis and designed items of the questionnaire based on semi-structured individual interviews with nursing students. Then, as the second step, psychometric properties of the questionnaire were evaluated using the face validity, content validity, construct validity, and internal consistency evaluated on 227 students from fourth or higher semesters. All the interviews were recorded and transcribed, and then, they were analyzed using Max Qualitative Data Analysis and all of qualitative data were analyzed using SPSS 14. Results To do the study, we constructed the preliminary questionnaire containing 102 expressions. After determination of face and content validities by qualitative and quantitative approaches, the expressions of the questionnaire were reduced to 45. To determine the construct validity, exploratory factor analysis was applied. The results indicated that the maximum variance percentage (40.55%) was defined by the first 3 factors while the rest of the total variance percentage (59.45%) was determined by the other 42 factors. Results of exploratory factor analysis of this questionnaire indicated the presence of 3 instructor-staff, students, and educational related factors. Finally, 41 expressions were kept in 3 factor groups. The α-Cronbach coefficient (0.93) confirmed the high internal consistency of the questionnaire. Conclusion Results indicated that the prepared questionnaire was an efficient instrument in the study of the effective factors on clinical learning as viewed by nursing students since it involves 41 expressions and

To determine the construct validity, exploratory factor analysis was applied. The results indicated that the maximum variance percentage (40.55%) was defined by the first 3 factors while the rest of the total variance percentage (59.45%) was determined by the other 42 factors. Results of exploratory factor analysis of this questionnaire indicated the presence of 3 instructor-staff, students, and educational related factors. Finally, 41 expressions were kept in 3 factor groups. The α-Cronbach coefficient (0.93) confirmed the high internal consistency of the questionnaire. Results indicated that the prepared questionnaire was an efficient instrument in the study of the effective factors on clinical learning as viewed by nursing students since it involves 41 expressions and properties such as instrument design based

This Swedish study reviewed differences in clinical presentation and laboratory findings of acute bacterial meningitis in children aged one month to 17 years in Västerbotten County, Sweden. A register-based study was performed for the period 1986 to 2013 using the Västerbotten County Council's patient registration and laboratory records at the Department of Laboratory Medicine at Umeå University Hospital. The medical records were reviewed to extract data and confirm the diagnosis. We found 103 cases of acute bacterial meningitis, and Haemophilus influenzae was the most common pathogen, causing 40.8% of all cases, followed by Streptococcus pneumoniae at 30.1% and Neisseria meningitidis at 9.7%. Significant differences in clinical presentation and laboratory findings were found. Younger children were more unwell than older ones and had more diffuse symptoms on admission. In addition, important sex-related differences were found that might explain the higher case fatality rates for boys than girls. For example, boys tended to have a higher disturbance in the blood-brain barrier, which is known to be a negative prognostic factor. This study showed that clinical presentation for acute bacterial meningitis varied with age and sex and, to a lesser extent, on the duration of the illness. ©2015 Foundation Acta Paediatrica.

Bringing new therapies to patients with rare diseases depends in part on optimizing clinical trial conduct through efficient study start-up processes and rapid enrollment. Suboptimal execution of clinical trials in academic medical centers not only results in high cost to institutions and sponsors, but also delays the availability of new therapies. Addressing the factors that contribute to poor outcomes requires novel, systematic approaches tailored to the institution and disease under study. To use clinical trial performance metrics data analysis to select high-performing cystic fibrosis (CF) clinical research teams and then identify factors contributing to their success. Mixed-methods research, including semi-structured qualitative interviews of high-performing research teams. CF research teams at nine clinical centers from the CF Foundation Therapeutics Development Network. Survey of site characteristics, direct observation of team meetings and facilities, and semi-structured interviews with clinical research team members and institutional program managers and leaders in clinical research. Critical success factors noted at all nine high-performing centers were: 1) strong leadership, 2) established and effective communication within the research team and with the clinical care team, and 3) adequate staff. Other frequent characteristics included a mature culture of research, customer service orientation in interactions with study participants, shared efficient processes, continuous process improvement activities, and a businesslike approach to clinical research. Clinical research metrics allowed identification of high-performing clinical research teams. Site visits identified several critical factors leading to highly successful teams that may help other clinical research teams improve clinical trial performance.

The aim of the study was to evaluate left ventricular diastolic function in workers occupationally exposed to mercury vapour without clinical presentation of cardiac involvement. The studies included 115 workers (92 men and 23 women) occupationally exposed to mercury vapour without clinical presentation of cardiac involvement (mean age: 47.83 ± 8.29). Blood samples were taken to determine blood lipid profile, urine was collected to estimate mercury concentration (Hg-U) and echocardiographic examination was performed to evaluate diastolic function of the left ventricle. In the entire group of workers occupationally exposed to mercury vapour without clinical presentation of cardiac involvement, Spearman correlationsmore » analysis demonstrated the following significant linear relationships: between body mass index (BMI) and ratio of maximal early diastolic mitral flow velocity/early diastolic mitral annular velocity (E/E') (r = 0.32, p < 0.05), between serum HDL concentration and E/E' (r = − 0.22, p < 0.05), between Hg-U and E/E' (r = 0.35, p < 0.05), between Hg-U and isovolumetric relaxation time (IVRT') (r = 0.41, p < 0.05), between Hg-U and ratio of maximal early diastolic mitral flow velocity/maximal late diastolic mitral flow velocity (E/A) (r = − 0.31, p < 0.05) and between serum HDL concentration and E/A (r = 0.43, p < 0,05). In logistic regression analysis it as shown that independent factors of left ventricular diastolic dysfunction risk in the study group included a higher urine mercury concentration, a higher value of BMI and a lower serum HDL concentration (OR{sub Hg}-{sub U} = 1.071, OR{sub BMI} = 1.200, OR{sub HDL} = 0.896, p < 0.05). Summing up, occupational exposure to mercury vapour may be linked to impaired left ventricular diastolic function in workers without clinical presentation of cardiac involvement. -- Highlights: ► Study aimed at evaluation of LVDD in workers occupationally exposed to Hg. ► There was significant linear

Clinical studies are being placed in emerging markets as part of global drug development programs to access large pool of eligible patients and to benefit from a cost effective structure. However, over the last few years, the definition of "emerging markets" is being revisited, especially from a regulatory perspective. For purposes of this article, countries outside US, EU and the traditional "western countries" are discussed. Multiple factors are considered for placement of clinical studies such as adherence to Good Clinical Practice (GCP), medical infrastructure & standard of care, number of eligible patients, etc. This article also discusses other quantitative factors such as country's GDP, patent applications, healthcare expenditure, healthcare infrastructure, corruption, innovation, etc. These different factors and indexes are correlated to the number of clinical studies ongoing in the "emerging markets". R&D, healthcare expenditure, technology infrastructure, transparency, and level of innovation, show a significant correlation with the number of clinical trials being conducted in these countries. This is the first analysis of its kind to evaluate and correlate the various other factors to the number of clinical studies in a country. © 2013.

High-grade dural arteriovenous fistulas (dAVFs) can present shunts with very different angio-architectural characteristics. Specific hemodynamic factors may affect clinical history and determine very different clinical courses. To evaluate the relationship between some venous angio-architectural features in high-grade dAVFs and clinical presentation. Specific indicators of moderate or severe venous hypertension were analyzed, such as altered configurations of the dural sinuses (by a single or a dual thrombosis), or overload of cortical vessels (restrictions of outflow, pseudophlebitic cortical vessels, and venous aneurysms). The institutional series was retrospectively reviewed (49 cases), and the pattern of venous drainage was analyzed in relationship with clinical presentation (benign/aggressive/hemorrhage). Thirty-five of 49 cases displayed cortical reflux (high-grade dAVFs). This subgroup displayed a benign presentation in 31.42% of cases, an aggressive in 31.42%, and hemorrhage in 37.14%. Our data confirm that within high-grade dAVFs, 2 distinct subpopulations exist according to severity of clinical presentation. Some indicators we examined showed correlation with aggressive nonhemorrhagic manifestations (outflow restriction and pseudophlebitic cortical vessels), while other showed a correlation with hemorrhage (dual thrombosis and venous aneurysms). Current classifications appear insufficient to identify a wide range of conditions that ultimately determine the organization of the cortical venous drainage. Intermediate degrees of venous congestion correlate better with the clinical risk than the simple definition of cortical reflux. The angiographic aspects of venous drainage presented in this study may prove useful to assess dAVF hemodynamic characteristics and identify conditions at higher clinical risk.

Urinary tract infection (UTI) often causes bacteremia, resulting in shock. The purpose of this study is to investigate urological bacteremia and bacteremia shock cases and seek for the clinical factors associated with urological bacteremic shock. Seventy consecutive cases with bacteremia caused by UTI from the Department of Urology, Kobe University Hospital were studied. These cases were diagnosed from 2000 to 2010 and had full data available for analysis. We investigated the potential clinical factors associated with bacteremic shock (systolic blood pressure ≤ 90 mmHg with UTI), including: (1) the number of basal general diseases (such as diabetes, malignancy, immune diseases, heart diseases, liver diseases, and kidney diseases), (2) causative bacteria, (3) antibiotics and therapeutic intervention, (4) gram-negative bacteria, (5) resistance to imipenem (which is often used in this infection), and (6) serum white blood cell counts and C-reactive protein (CRP) at the time of diagnosis of bacteremic UTI. A total of 81 causative bacteria were isolated: 42 cases were gram-negative and 39 were gram-positive bacteria. In detail, Escherichia coli was the most common, followed by Methicillin-resistant Staphylococcus aureus. The comparison data revealed that urological bacteremic shock cases had significantly increased CRP (p < 0.001). Our univariate analyses showed indwelling urinary tract catheters (p = 0.02) as a significant clinical factor associated with urological bacteremic shock and multivariate analyses showed that the presence of indwelling urinary tract catheters before UTI was a significant clinical factor associated with urological bacteremic shock (p = 0.04). Indwelling urinary catheters before UTI and high CRP were clinical factors associated with urological bacteremic shock. This result should be considered during decision-making for UTI treatments in high risk cases or urological bacteremia cases.

Retrospective cohort study. To describe the demographics, clinical presentation, and functional outcomes of fibrocartilaginous embolic myelopathy (FCEM). Academic inpatient rehabilitation unit in the midwestern United States. We retrospectively searched our database to identify patients admitted between January 1, 1995 and March 31, 2016, with a high probability of FCEM. Demographic, clinical, and functional outcome measures, including Functional Independence Measure (FIM) information was obtained by chart review. We identified 31 patients with findings suggestive of FCEM (52% male), which was 2% of the nontraumatic spinal cord injury population admitted to inpatient rehabilitation. The age distribution was bimodal, with peaks in the second and sixth-to-seventh decades. The most common clinical presentation was acute pain and rapid progression of neurologic deficits consistent with a vascular myelopathy. Only three patients (10%) had FCEM documented as a diagnostic possibility. Most patients had paraplegia and neurologically incomplete injuries and were discharged to home. Nearly half of the patients required no assistive device for bladder management at discharge, but most were discharged with medications for bowel management. Median FIM walking locomotion score for all patients was 5, but most patients were discharged using a wheelchair for primary mobility. Median motor FIM subscale score was 36 at admission and 69 at discharge, with a median motor efficiency of 1.41. FCEM may be underdiagnosed and should be considered in those with the appropriate clinical presentation, because their functional outcomes may be more favorable than those with other causes of spinal cord infarction.

Congenital anatomic abnormality of the inferior vena cava (IVC) is an important risk factor for the development of spontaneous proximal lower extremity deep vein thrombosis (DVT) in young adults. The incidence of DVT associated with congenital IVC anomalies in paediatric populations has not been described, and the implications of IVC anomalies for treatment and outcomes of DVT are unknown. This study reports a series of five adolescent males with spontaneous lower extremity DVTs and underlying congenital IVC abnormalities. Cases were identified by searching the institutional database of patients treated with anticoagulation for venous thromboembolism at a tertiary children's hospital. The demographics, clinical presentations, imaging findings, treatment courses, and outcomes are described. All cases occurred in males, and accounted for approximately twenty percent of adolescent males presenting with DVT. IVC abnormality is likely an under-recognized risk factor for DVT in this age group, and detailed vascular imaging should be pursued in adolescents with spontaneous proximal lower extremity DVT when initial ultrasonography does not delineate the proximal clot extent. Management requires individual risk-benefit assessment in the context of providing developmentally appropriate care. Further research is required to establish long-term outcomes and determine optimal treatment strategies. Copyright © 2015 Elsevier Ltd. All rights reserved.

To determine different clinical presentationsand disease location demarcatedby upper and lower gastrointestinal endoscopyand relevant histopathologyin children diagnosed with inflammatory bowel disease (IBD). This is 5 years (2010 to 2015) retrospective studyconducted at the Aga Khan University Hospitalenrolling65admitted children between 6 months to 15years from either gender, diagnosed with IBD on clinical presentation, endoscopy and biopsy. Different clinical presentations at the time of diagnosis were noted in different categories of the disease. All patients underwent upper and lower (up to the terminal ileum) endoscopy with multiple punch biopsies and histologic assessment of mucosal specimens. All endoscopies were done by paediatric gastroenterologists at endoscopy suite of the hospital and all specimens were reported by the pathology department. ESPGHAN revised criteria for the diagnosis of inflammatory bowel disease in children and an adolescent was used to standardize our diagnosis. Extent of disease on endoscopy and relevant histopathology of the biopsy samples were noted at the time of diagnosis. Data was summarized using mean, standard deviation, numbers and percentages for different variables. Total 56 children were enrolled according to inclusion criteria. There were 34children (61.53%) diagnosed with ulcerative colitis (UC), 10 patients (16.92%) had Crohn'sDisease (CD) and 11 (21.53%) patients were labeled as Indeterminate colitis (IC). Mean age at onset of symptoms was10.03±2.44 and mean age at diagnosis was11.10±2.36. Abdominal pain (80%) and chronic diarrhea (70%) were common symptoms in CD whereas bloody diarrhea (79.41%) and rectal bleeding(64.70%)were common presentation in UC. Patients diagnosed with indeterminate colitis(IC) had similar clinical features as in UC patients. Only 7% patients had some extra-intestinal features in the form of joint pain and/or uveitis. Aspartate aminotransferase level (95.18 ±12.89) was relatively high in

Optic pathway gliomas (OPGs) occur sporadically or in patients with neurofibromatosis type 1 (NF1). The purpose of this study was to evaluate the clinical presentation at diagnosis and at progression of patients with OPGs. We conducted a chart review of patients with OPGs diagnosed in a single center over a period of 15 years. Demographic data including age, sex, NF1 status, clinical presentation, and outcome were collected. Of the 40 patients who were identified, 23 had sporadic tumors (57.5%) and 17 had NF1-related tumors (42.5%). Among the children with NF1, there was a significant overrepresentation of girls (82.3%) (P = 0.02), while among the children without NF1, there were slightly more boys (56.5%) than girls (43.5%). The presence of nystagmus was strongly associated with sporadic optic pathway gliomas. Poor visual outcome was related to tumor affecting both optic pathways, hydrocephalus at diagnosis, and optic nerve atrophy. Of the 40 patients, five died of OPG complications (12.5%) and all had sporadic tumors. Our cohort is one of the largest with OPGs and a detailed description of the clinical presentation both at diagnosis and at progression. We observed a significant difference between sporadic and NF1 optic pathway gliomas in terms of demographics, clinical presentation, and outcome. Copyright © 2017 Elsevier Inc. All rights reserved.

Objective To explore associated clinical factors in children with pediatric autoimmune neuropsychiatric disorders associated with streptococcus (PANDAS). Study design Children with tics and/or OCD (n = 109) were examined by personal and family history, diagnostic interview, physical examination, medical record review, and measurement of baseline levels of streptococcal antibodies. Results Significant group differences were found on several variables, such that those diagnosed with PANDAS (versus without PANDAS) were more likely to have had dramatic onset; definite remissions; remission of neuropsychiatric symptoms during antibiotic therapy; a history of tonsillectomies/adenoidectomies; evidence of GAS infection, and clumsiness. Conclusion The identification of clinical features associated with PANDAS should assist in delineating risks for this subtype of OCD/tics. PMID:21868033

In the context of forthcoming initiation of Diagnosis Related Groups (DRG) in Switzerland, the objective of the study was to find factors having an impact on the inpatient's length of hospital stay. The study was performed on two general-medical wards of the Kantonsspital Winterthur, where all admitted patients were included in the study over two months. The various periods of diagnostic and therapeutic management of the patients and all diagnostic and therapeutic measures plus the arrangements after hospitalization were recorded. The determinants influencing the length of hospital stay were classified in clinic-internal or -external. 124 inpatients entered the study. 91 (73.4%) had a length of hospital stay without delay, whereas 33 (26.6%) patients had an extended length of hospital stay. The cumulative length of hospital stay of all patients was 1314 days, whereof 216 days (16.4%) were caused by delays. 67 days were caused by clinic-internal (5.1%) and 149 days by clinic-external factors (11.3%). Delays were substantially more generated by clinic-internal than -external factors. Clinic-internal factors were mainly weekends with interruption of the diagnostic and therapeutic procedures, dead times waiting for diagnostic results and waiting times for consultations. Clinic-external factors were caused by delayed transfer in nursing homes or rehabilitation institutions, waiting for family members for the backhaul and by indetermination of the patient. Also factors relating to the patients' characteristics had an influence on the length of hospital stay. Summing up, a substantial part of the length of hospital stay was caused by delays. However, the many different clinic-internal factors complicate solutions to lower the length of hospital stay. Moreover, factors that cannot be influenced such as waiting for microbiological results, contribute to extended length of hospital stay. Early scheduling of post-hospital arrangements may lower length of hospital stay

Factor VII Deficiency: Clinical Phenotype, Genotype and Therapy.

Factor VII deficiency is the most common among rare inherited autosomal recessive bleeding disorders, and is a chameleon disease due to the lack of a direct correlation between plasma levels of coagulation Factor VII and bleeding manifestations. Clinical phenotypes range from asymptomatic condition-even in homozygous subjects-to severe life-threatening bleedings (central nervous system, gastrointestinal bleeding). Prediction of bleeding risk is thus based on multiple parameters that challenge disease management. Spontaneous or surgical bleedings require accurate treatment schedules, and patients at high risk of severe hemorrhages may need prophylaxis from childhood onwards. The aim of the current review is to depict an updated summary of clinical phenotype, laboratory diagnosis, and treatment of inherited Factor VII deficiency.

The aim of this study is to determine the epidemiological features, clinical presentation, and treatment of children with septic arthritis. A retrospective review was conducted on a total of 141 children with septic arthritis treated in Hospital Universitario La Paz (Madrid) between the years 2000 to 2013. The patient data collected included, the joint affected, the clinical presentation, the laboratory results, the appearance, Gram stain result, and the joint fluid culture, as well as the imaging tests and the treatment. Most (94%) of the patients were less than 2 years-old. The most common location was the knee (52%), followed by the hip (21%). The septic arthritis was confirmed in 53%. No type of fever was initially observed in 49% of them, and 18% had an ESR (mm/h) or CRP (mg/l) less than 30 in the initial laboratory analysis. The joint fluid was purulent in 45% and turbid in 12%. The Gram stain showed bacteria in 4%. The fluid culture was positive in 17%. Staphylococcus aureus was the most common pathogen found, followed by Streptococcus agalactiae, Streptococcus pneumoniae, and Kingella kingae. Antibiotic treatment was intravenous administration for 7 days, followed by 21 days orally. Surgery was performed in 18% of cases. The diagnosis was only confirmed in 53% of the patients. Some of the confirmed septic arthritis did not present with the classical clinical/analytical signs, demonstrating that the traumatologist or paediatrician requires a high initial level of clinical suspicion of the disease.

Pregnancy-related lumbopelvic pain has puzzled medicine for a long time. The present systematic review focuses on terminology, clinical presentation, and prevalence. Numerous terms are used, as if they indicated one and the same entity. We propose "pregnancy-related pelvic girdle pain (PPP)", and "pregnancy-related low back pain (PLBP)", present evidence that the two add up to "lumbopelvic pain", and show that they are distinct entities (although underlying mechanisms may be similar). Average pain intensity during pregnancy is 50 mm on a visual analogue scale; postpartum, pain is less. During pregnancy, serious pain occurs in about 25%, and severe disability in about 8% of patients. After pregnancy, problems are serious in about 7%. The mechanisms behind disabilities remain unclear, and constitute an important research priority. Changes in muscle activity, unusual perceptions of the leg when moving it, and altered motor coordination were observed but remain poorly understood. Published prevalence for PPP and/or PLBP varies widely. Quantitative analysis was used to explain the differences. Overall, about 45% of all pregnant women and 25% of all women postpartum suffer from PPP and/or PLBP. These values decrease by about 20% if one excludes mild complaints. Strenuous work, previous low back pain, and previous PPP and/or PLBP are risk factors, and the inclusion/exclusion of high-risk subgroups influences prevalence. Of all patients, about one-half have PPP, one-third PLBP, and one-sixth both conditions combined. Overall, the literature reveals that PPP deserves serious attention from the clinical and research communities, at all times and in all countries.

2013-01-01

Darier's disease, also known as keratosis follicularis or dyskeratosis follicularis, is a rare disorder of keratinization. It is an autosomal dominant genodermatosis with high penetrance and variable expressivity. Its manifestation appears as hyperkeratotic papules, primarily affecting seborrheic areas on the head, neck, and thorax and less frequently on the oral mucosa. When oral manifestations are present, the palatal and alveolar mucosae are primarily affected. They are usually asymptomatic and are discovered in routine dental examination. Histologically, the lesions are presented as suprabasal clefts in the epithelium with acantholytic and dyskeratotic cells represented by “corps ronds and grains”. This paper reports a case of a 53-year-old woman that was admitted to our clinic with more than 10-year history of keratotic papules, presented on the hands and feet, nose, ears, genitalia, and whitish lesions on palatal mucosae.

To review a single institution's 15-year experience with urethral foreign bodies, including evaluation, clinical findings, and treatment. In total, 27 patients comprising 35 episodes of inserted urethral foreign bodies were reviewed at Cook County Hospital between 2000 and 2015. Retrospective chart review was performed to describe the clinical presentation, rationale for insertion, management, recidivism, and sequelae. Median patient age was 26 (range 12-60). Twenty-six patients (97 %) were male, 1 was female (3%). Items inserted included pieces of plastic forks, spoons, metal screws and aluminum, pieces of cardboard or paper, staples, writing utensils such as pens and pencils, as well as coaxial cable and spray foam sealant. Reported reasons for insertion were self-stimulation, erectile enhancement, and attention seeking. Presenting symptoms included dysuria, gross hematuria, urinary retention, urinary tract infection, and penile discharge. The most common technique for removal was manual extraction with extrinsic pressure (n = 19, 54%). Other methods include endoscopic retrieval (n = 8, 23%), open cystotomy (n = 1, 3%), and voiding to expel the foreign body (n = 7, 20%). Postremoval complications included urinary tract infection (n = 7), sepsis (n = 4), urethral false passage (n = 5), laceration (n = 5), and stricture (n = 1). We present the largest single-institutional series of urethral foreign bodies to date. Urethral foreign body insertion is a relatively rare occurrence and, commonly, is a recurrent behavior. Urethral trauma related to foreign body insertion is associated with significant risk of infection and urethral injury with long-term sequelae. Copyright © 2016 Elsevier Inc. All rights reserved.

Metabolic syndrome pathophysiology and clinical presentation.

PubMed

Handelsman, Yehuda

2009-01-01

Metabolic syndrome is a relatively new definition, designed to help the health care practitioner to easily identify people at risk for the development of cardiovascular disease and diabetes. With the obesity epidemic, we are witnessing an epidemic of multiple-risk patients. Insulin resistance is the perceived pathophysiology of metabolic syndrome and defines its clinical presentation. Hypertension, dyslipedemia, polycystic ovarian syndrome, fatty liver disease, pre-diabetes, sleep and breathing disorder, certain cancers, and cognitive impairment are many of the presentations of the syndrome; patients with any of these conditions are at a high risk of developing cardiovascular disease and diabetes. The metabolic syndrome helps identify people at risk to allow early intervention for prevention. Lifestyle modification is the most important part of the management of people with the syndrome. Lately medications--though none approved by the U.S. Food and Drug Administration (FDA)--have been recommended by major medical societies when lifestyle modification is not enough or when it fails.

Dissociative absorption: An empirically unique, clinically relevant, dissociative factor.

PubMed

Soffer-Dudek, Nirit; Lassri, Dana; Soffer-Dudek, Nir; Shahar, Golan

2015-11-01

Research of dissociative absorption has raised two questions: (a) Is absorption a unique dissociative factor within a three-factor structure, or a part of one general dissociative factor? Even when three factors are found, the specificity of the absorption factor is questionable. (b) Is absorption implicated in psychopathology? Although commonly viewed as "non-clinical" dissociation, absorption was recently hypothesized to be specifically associated with obsessive-compulsive symptoms. To address these questions, we conducted exploratory and confirmatory factor analyses on 679 undergraduates. Analyses supported the three-factor model, and a "purified" absorption scale was extracted from the original inclusive absorption factor. The purified scale predicted several psychopathology scales. As hypothesized, absorption was a stronger predictor of obsessive-compulsive symptoms than of general psychopathology. In addition, absorption was the only dissociative scale that longitudinally predicted obsessive-compulsive symptoms. We conclude that absorption is a unique and clinically relevant dissociative tendency that is particularly meaningful to obsessive-compulsive symptoms. Copyright © 2015 Elsevier Inc.

To investigate the role of alcoholic aetiology on clinical presentation, treatment and outcome of HCC as well as on each Barcelona Clinic Liver Cancer (BCLC) stage, as compared to HCV-related HCCs. A total of 1642 HCV and 573 alcoholic patients from the Italian Liver Cancer (ITA.LI.CA) database, diagnosed with HCC between January 2000 and December 2012 were compared for age, gender, type of diagnosis, tumour burden, portal vein thrombosis (PVT), oesophageal varices, liver function tests, alpha-fetoprotein, BCLC, treatment and survival. Aetiology was tested as predictor of survival in multivariate Cox regression models and according to HCC stages. Cirrhosis was present in 96% of cases in both groups. Alcoholic patients were younger, more likely male, with HCC diagnosed outside surveillance, in intermediate/terminal BCLC stage and had worse liver function. After adjustment for the lead-time, median (95% CI) overall survival (OS) was 27.4 months (21.5-33.2) in alcoholic and 33.6 months (30.7-36.5) in HCV patients (P = 0.021). The prognostic role of aetiology disappeared when survival was assessed in each BCLC stage and in the Cox regression multivariate models. Alcoholic aetiology affects survival of HCC patients through its negative effects on secondary prevention and cancer presentation but not through a greater cancer aggressiveness or worse treatment result. In fact, survival adjusted for confounding factors was similar in alcoholic and HCV patients. © 2015 John Wiley & Sons Ltd.

Social cognition is consistently impaired in people with schizophrenia, separable from general neurocognition, predictive of real-world functioning and amenable to psychosocial treatment. Few studies have empirically examined its underlying factor structure. This study (1) examines the factor structure of social cognition in both a sample of individuals with schizophrenia-spectrum disorders and non-clinical controls and (2) explores relationships of factors to neurocognition, symptoms and functioning. A factor analysis was conducted on social cognition measures in a sample of 65 individuals with schizophrenia or schizoaffective disorder, and 50 control participants. The resulting factors were examined for their relationships to symptoms and functioning. Results suggested a two-factor structure in the schizophrenia sample (social cognition skill and hostile attributional style) and a three-factor structure in the non-clinical sample (hostile attributional style, higher-level inferential processing and lower-level cue detection). In the schizophrenia sample, the social cognition skill factor was significantly related to negative symptoms and social functioning, whereas hostile attributional style predicted positive and general psychopathology symptoms. The factor structure of social cognition in schizophrenia separates hostile attributional style and social cognition skill, and each show differential relationships to relevant clinical variables in schizophrenia.

Depressed inpatients constitute a high-risk population for suicide attempts. To describe the interactions of clinical and psychosocial risk factors influencing suicide attempts among a Malaysian sample of depressed inpatients. Seventy-five subjects were diagnosed with a depressive disorder according to the Structured Clinical Interview for DSM-IV Axis I Disorders-Clinical Version (SCID-CV). Data on suicide attempts, suicidal ideation (Scale for Suicidal Ideation, SSI), depression severity (Beck's Depression Inventory, BDI), recent life-event changes (Social Readjustment Rating Scale, SRRS), sociodemographic and other relevant clinical factors were collected. A third of the subjects presented after a current suicide attempt. Significant factors for a current suicide attempt were race, religion, recent life-event changes, suicidal ideation, and alcohol use disorder. Independent predictive risk factors for a current suicide attempt were Chinese race, recent marital separation, major mortgage or loans, and being newly diagnosed with depression. Any recent change in personal habits was shown to be a protective factor against current suicide attempt. Age and gender were nonsignificant factors. The findings are generally consistent with existing studies and highlight the role of psychosocial risk factors.

We developed a multi-modality image presentation software for display and analysis of images and related data from different imaging modalities. The software is part of a cardiac image review and presentation platform that supports integration of digital images and data from digital and analog media such as videotapes, analog x-ray films and 35 mm cine films. The software supports standard DICOM image files as well as AVI and PDF data formats. The system is integrated in a digital conferencing room that includes projections of digital and analog sources, remote videoconferencing capabilities, and an electronic whiteboard. The goal of this pilot project is to: 1) develop a new paradigm for image and data management for presentation in a clinically meaningful sequence adapted to case-specific scenarios, 2) design and implement a multi-modality review and conferencing workstation using component technology and customizable 'plug-in' architecture to support complex review and diagnostic tasks applicable to all cardiac imaging modalities and 3) develop an XML-based scripting model of image and data presentation for clinical review and decision making during routine clinical tasks and multidisciplinary clinical conferences.

Clinical risk factors for venous thrombosis associated with air travel.

Kesteven, P J; Robinson, B J

2001-02-01

Recent reports have linked air travel with venous thrombo-embolism (VTE). Risk factors and associated features of this link are poorly understood. We have accumulated clinical data from a relatively large cohort of patients with traveler's thrombosis. A total of 86 patients who developed venous thromboembolism within 28 d of flying were questioned concerning traveling habits, medical history (including risk factors for VTE) and characteristics of the index flight. Of the patients, 72% had at least one risk factor for VTE (excluding thrombophilia) prior to their flight. Of interest, 87% of VTE cases occurred following either a return trip or after an outward journey involving long trips made up of sequential flights. In only two cases could no identifiable risk factor or earlier journey be found. Duration of flights ranged from 2 to 30 h. Of responders, 38% presented with chest symptoms; 92% with VTE developed symptoms within 96 h of their flight. We conclude that the majority of VTE associated with air travel occur in those with identifiable risk factors prior to their flight, and that sequential flights may increase this risk.

Few studies have been reported from the Kingdom of Saudi Arabia (SA) to describe the clinical presentation and long term outcomes of subacute thyroiditis (SAT). Our aim was to review the demographic, anthropometric, clinical presentation, laboratory results, treatment, and disease outcome in Riyadh region and to compare those with results from different regions of the Kingdom and different parts of the world. We reviewed the medical files of patients who underwent thyroid uptake scan during an 8-year period in King Khalid University Hospital. Only 25 patients had confirmed diagnosis of thyroiditis. Age and gender distribution were similar to other studies. Most patients presented with palpitation, goiter, and weight change. Elevated thyroid hormones, suppressed thyroid-stimulating hormone, and elevated ESR were reported. Among those, 7 cases of SAT were recorded. β-Blockers were prescribed to 57% and nonsteroidal anti-inflammatory drugs to 29% of SAT. Long follow-up demonstrated that 85.7% of SAT cases recovered, while 14.3% developed permanent hypothyroidism. In conclusion, SAT is uncommon in the central region of SA. Compared to the western region, corticosteroid is not commonly prescribed, and permanent hypothyroidism is not uncommon. A nation-wide epidemiological study to explain these interprovincial differences is warranted. PMID:24803929

Impulse control disorders (ICD) constitute a complication that may arise during the course of Parkinson's disease (PD). Several factors have been linked to the development of these disorders, and their associated severe functional impairment requires specific and multidisciplinary management. The objective of this study was to evaluate the frequency of ICDs and the clinical and psychopathological factors associated with the appearance of these disorders. Cross-sectional, descriptive, and analytical study of a sample of 115 PD patients evaluated to determine the presence of an ICD. Clinical scales were administered to assess disease severity, personality traits, and presence of psychiatric symptoms at the time of evaluation. Of the 115 patients with PD, 27 (23.48%) displayed some form of ICD; hypersexuality, exhibited by 14 (12.2%), and binge eating, present in 12 (10.1%), were the most common types. Clinical factors associated with ICD were treatment with dopamine agonists (OR: 13.39), earlier age at disease onset (OR: 0.92), and higher score on the UPDRS-I subscale; psychopathological factors with a significant association were trait anxiety (OR: 1.05) and impulsivity (OR: 1.13). ICDs are frequent in PD, and treatment with dopamine agonists is the most important risk factor for these disorders. High impulsivity and anxiety levels at time of evaluation, and younger age at disease onset, were also linked to increased risk. However, presence of these personality traits prior to evaluation did not increase risk of ICD. Copyright © 2015 Sociedad Española de Neurología. Published by Elsevier España, S.L.U.

The study was designed to present and apply theoretical and empirical knowledge for the construction of a clinical model intended to shift the attention of the general practitioner from objective risk factors to self-assessed health resources in male and female patients. Review, discussion and analysis of selected theoretical models about personal health resources involving assessing existing theories according to their emphasis concerning self-assessed vs. doctor-assessed health resources, specific health resources vs. life and coping in general, abstract vs. clinically applicable theory, gender perspective explicitly included or not. Relevant theoretical models on health and coping (salutogenesis, coping and social support, control/demand, locus of control, health belief model, quality of life), and the perspective of the underprivileged Other (critical theory, feminist standpoint theory, the patient-centred clinical method) were presented and assessed. Components from Antonovsky's salutogenetic perspective and McWhinney's patient-centred clinical method, supported by gender perspectives, were integrated to a clinical model which is presented. General practitioners are recommended to shift their attention from objective risk factors to self-assessed health resources by means of the clinical model. The relevance and feasibility of the model should be explored in empirical research.

Paracoccidioidomycosis (PCM) is a systemic fungal disease endemic to Latin America and characterized by two clinical presentations, i.e., patients develop either acute/subacute or chronic clinical manifestations. The differences in clinical presentations are mainly dependent on the host immune response, but may also be related to demographic characteristics of some patients. In this retrospective study, 1,219 PCM cases treated between 1970 and 2009 in a university medical center, located in southeastern Brazil, were analyzed according to their clinical and demographic features. The most affected anatomical sites were lungs (63.8%) and oral mucosa (50.0%), with increasing involvement of these sites in accord with the age of the patients. Generalized lymphadenopathy (28.1%) and skin lesions (29.6%) were more frequent on the first decades of life. Involvement of the larynx (16.1%), gut (7.5%), spleen (4.7%), central nervous system (3.4%), bones and joints (2.2%), and adrenal (2.1%) were also variable according to the age of the host. The acute/subacute form of the disease accounted for 26.4% of PCM cases and, on a multivariate analysis, was inversely associated with aging (OR = 0.8 per year, P < 0.001), and directly associated with female sex (OR = 7.2, P < 0.001), mixed black and white racial background (OR = 2.3, P < 0.001) or black skin color (OR = 4.6, P < 0.001). Based on these findings, we have shown that host immune response, as well as age, gender and ethnicity may influence the clinical presentation of PCM.

To study the clinical presentation of femoral head osteonecrosis (ONFH). Publications dedicated to this aspect of ONFH are rare. Our aim was to systematically collect and describe the clinical data. A prospective survey was conducted in a cohort of ONFH recruited from a dedicated clinic for osteonecrosis. The history of symptoms, medical management, and physical findings were obtained from 88 patients suffering from 125 ONFH. Subgroups were formed: bilateral versus unilateral ONFH, radiological stages 1-2 (pre-fractured) versus fractured stage 3 versus stage 4. ONFH was bilateral in 63 %, especially in corticosteroid users and in sickle-cell cases. These patients were younger but had similar BMIs compared to the unilateral cases. The pain was mechanical in 79 % of hips and inflammatory in 21 %. Acute pain at the onset was present in 55 % of hips. The localization of this pain was variable, including in the groin, the buttocks, or diffused in the lower limbs. A limp was present in 50 % of the patients, only when one hip was painful. The physical examination of the hip was normal in 31 %, especially in stages 1-2 (55 %). The diagnosis delay was 12 months, with inadequate medical management in 51 % of patients. In ONFH cases, no typical clinical pattern was found. The clinical presentation was very variable, sometimes having spine or knee symptoms with a normal physical examination of the hip. ONFH should be systematically suspected in cases of onset of pain in the pelvis, buttocks, groin, and lower limbs.

To evaluate the clinical presentation of retinoblastoma in Alexandria, Egypt, correlate the timing of accurate diagnosis with the presence of advanced disease and identify causes of delayed presentation. Retrospective noncomparative single institution study reviews demographic and clinical data of all new children with retinoblastoma presenting to Alexandria Main University ocular oncology clinic (OOC) from January 2012 to June 2014. Diagnosis time was from initial parental complaint to retinoblastoma diagnosis and referral time was from retinoblastoma diagnosis to presentation to the Alexandria OCC. Delayed Diagnosis and referral were counted if >2 weeks. Advanced presentation is defined as clinical TNMH (8th edition) staging of cT2 or cT3 (international intraocular retinoblastoma classification group D or E) in at least one eye or the presence of extra-ocular disease (cT4). Seventy eyes of 47 children were eligible: 52% unilateral, 7% with family history and 96% presented with leukocorea. Sixty-four percent of children had advanced intraocular disease and none had extra-ocular disease. Delayed presentation occurred in 58% of children and was significantly associated with advanced disease in both unilaterally and bilaterally affected children (p = 0.003, 0.002 respectively). The delay in diagnosis was more in unilateral cases while the delay in referral was more in bilateral cases. The main cause of delayed presentation in unilateral retinoblastoma was misdiagnosis (30%) while parental shopping for second medical opinion (30%) was the main cause in bilateral children. Delayed diagnosis is a problem affecting retinoblastoma management. Better medical education and training, health education and earlier screening are recommended to achieve earlier diagnosis.

Aim: To identify predisposing factors and to define clinical and microbiological characteristics of bacterial keratitis in current practice. Methods: A retrospective analysis of the hospital records of patients presenting with bacterial keratitis and treated at the Quinze-Vingts National Center of Ophthalmology, Paris, France, was performed during a 20 month period. A bacterial keratitis was defined as a suppurative corneal infiltrate and overlying epithelial defect associated with presence of bacteria on corneal scraping and/or that was cured with antibiotic therapy. Risk factors, clinical and microbiological data were collected. Results: 300 cases (291 patients) of presumed bacterial keratitis were included. Potential predisposing factors, usually multiple, were identified in 90.6% of cases. Contact lens wear was the main risk factor (50.3%). Trauma or a history of keratopathy was found in 15% and 21% of cases, respectively. An organism was identified in 201 eyes (68%). 83% of the infections involved Gram positive bacteria, 17% involved Gram negative bacteria, and 2% were polymicrobial. Gram negative bacteria were associated with severe anterior chamber inflammation (p=0.004), as well as greater surface of infiltrates (p=0.01). 99% of ulcers resolved with treatment, but only 60% of patients had visual acuity better than the level at admission, and 5% had very poor visual outcome. Conclusions: Contact lens wear is the most important risk factor. Most community acquired bacterial ulcers resolve with appropriate treatment. PMID:12812878

There is often a need to reduce sample size in clinical trials due to practical limitations and ethical considerations. Better comparability between treatment groups by use of stratification in the design, and use of continuous outcome variables in the evaluation of treatment results, are two methods that can be used in order to achieve this. In this paper the choice of stratification factors in trials of clinical mastitis in dairy cows is investigated, and two score-scales for evaluation of clinical mastitis are introduced. The outcome in 57 dairy cows suffering from clinical mastitis and included in a clinical trial comparing homeopathic treatment, placebo and a standard antibiotic treatment is investigated. The strata of various stratification factors are compared across treatments to determine which other factors influence outcome. The two score scales, measuring acute and chronic mastitis symptoms, respectively, are evaluated on their ability to differentiate between patients classified from clinical criteria as responders or non-responders to treatment. Differences were found between the strata of the factors severity of mastitis, lactation number, previous mastitis this lactation and bacteriological findings. These factors influence outcome of treatment and appear relevant as stratification factors in mastitis trials. Both score scales differentiated between responders and non-responders to treatment and were found useful for evaluation of mastitis and mastitis treatment.

OBJECTIVE Invasive candidiasis is a leading cause of infection-related morbidity and mortality in extremely low-birth-weight (<1000 g) infants. We quantify risk factors predicting infection in high-risk premature infants and compare clinical judgment with a prediction model of invasive candidiasis. METHODS The study involved a prospective observational cohort of infants <1000 g birth weight at 19 centers of the NICHD Neonatal Research Network. At each sepsis evaluation, clinical information was recorded, cultures obtained, and clinicians prospectively recorded their estimate of the probability of invasive candidiasis. Two models were generated with invasive candidiasis as their outcome: 1) potentially modifiable risk factors and 2) a clinical model at time of blood culture to predict candidiasis. RESULTS Invasive candidiasis occurred in 137/1515 (9.0%) infants and was documented by positive culture from ≥ 1 of these sources: blood (n=96), cerebrospinal fluid (n=9), urine obtained by catheterization (n=52), or other sterile body fluid (n=10). Mortality was not different from infants who had positive blood culture compared to those with isolated positive urine culture. Incidence varied from 2–28% at the 13 centers enrolling ≥ 50 infants. Potentially modifiable risk factors (model 1) included central catheter, broad-spectrum antibiotics (e.g., third-generation cephalosporins), intravenous lipid emulsion, endotracheal tube, and antenatal antibiotics. The clinical prediction model (model 2) had an area under the receiver operating characteristic curve of 0.79, and was superior to clinician judgment (0.70) in predicting subsequent invasive candidiasis. Performance of clinical judgment did not vary significantly with level of training. CONCLUSION Prior antibiotics, presence of a central catheter, endotracheal tube, and center were strongly associated with invasive candidiasis. Modeling was more accurate in predicting invasive candidiasis than clinical judgment. PMID

Since its discovery, nerve growth factor (NGF) has long occupied a critical role in developmental and adult neurobiology for its many important regulatory functions on the survival, growth and differentiation of nerve cells in the peripheral and central nervous system. NGF is the first discovered member of a family of neurotrophic factors, collectively indicated as neurotrophins, (which include brain-derived neurotrophic factor, neurotrophin-3 and neurotrophin 4/5). NGF was discovered for its action on the survival and differentiation of selected populations of peripheral neurons. Since then, an enormous number of basic and human studies were undertaken to explore the role of purified NGF to prevent the death of NGF-receptive cells. These studies revealed that NGF possesses important therapeutic properties, after topical administration, on human cutaneous pressure ulcer, corneal ulcers, glaucoma, retinal maculopathy, Retinitis Pigmentosa and in pediatric optic gliomas and brain traumas. The aim of this review is to present our previous, recent and ongoing clinical studies on the therapeutic properties of NGF.

This article aims to deconstruct various design qualities and strategies of clinic exam rooms, and discuss how they influence users' interaction and behavior in the space. Relevant literature supports the advantages and disadvantages of different design strategies. Annotated exam room prototypes illustrate the design qualities and strategies discussed. Advancements in technology and medicine, along with new legislative policies, are influencing the way care providers deliver care and ultimately clinic exam room designs. The patient-centered medical home model has encouraged primary care providers to make patients more active leaders of their health plan which will influence the overall functionality and configuration of clinic exam rooms. Specific design qualities discussed include overall size, location of doors and privacy curtains, positioning of exam tables, influence of technology in the consultation area, types of seating, and placement of sink and hand sanitizing dispensers. In addition, future trends of exam room prototypes are presented. There is a general lack of published evidence to support design professionals' design solutions for outpatient exam rooms. Future research should investigate such topics as the location of exam tables and privacy curtains as they relate to patient privacy; typical size and location of consultation table as it relates to patient connection and communication; and placement of sinks and sanitization dispensers as they relate to frequency and patterns of usage. Literature review, outpatient, technology, visual privacy.

An unusual case of a 75-year-old man is presented who had multiple stress fractures due to adult onset hypophosphatemic osteomalacia, which was the result of Fanconi syndrome, with light chain cast proximal tubulopathy due to multiple myeloma. A 75-year-old man presented with diffuse pain and muscle weakness. He had multiple stress fractures, low serum phosphate, decreased renal tubular reabsorption of phosphate, and normal PTH and FGF23, indicating adult onset hypophosphatemic osteomalacia. Phosphate supplements with calcitriol resulted in clinical recovery and healing of stress fractures. Because of proteinuria, a renal biopsy was performed that revealed Fanconi syndrome with light chain cast proximal tubulopathy and light kappa chains were found in serum and urine. A bone biopsy confirmed the diagnosis of multiple myeloma, and treatment with chemotherapy resulted in cytological and clinical recovery.

Childhood disintegrative disorder with seasonal total mutism: A rare clinical presentation

2016-01-01

Childhood disintegrative disorder (CDD) is a rare autistic-like clinical condition with unknown etiology, in that previously acquired age-appropriate language, social and adaptive abilities deteriorate significantly in 2-10-year-old healthy children, although physical and neurological evaluations display no observable abnormality. Our case is a 22-year-old female born of a consanguineous marriage, with the appearance of CDD symptoms in her fifth year of age following normal mental and physical development during her initial four years of life. Without any precipitating factor, she gradually lost her language abilities, social relational skills, affectionate behavior, adaptive capacities, peer play and meaningful interest in her surrounding, friends and family members over a period of 4 years, reaching a plateau in her ninth year of age. The unique special clinical symptom in this case is a seasonal total mutism, which after the beginning of her CDD symptoms is revealing every year covering the spring. As no additional physical or psychological change accompanies her total seasonal speech loss, it cannot be attributed to any mental condition known as having a seasonal pattern. Because in the literature CDD is presented mostly as case reports with lacking of advanced research data, describing any new case is recommended to improve the knowledge about this rare condition, especially if it displays some new unusual signs, not reported till now.

Aim To analyse the clinical presentation, identify predisposing risk factors and evaluate the outcome of treatment of Moraxella keratitis. Methods A retrospective analysis was carried out of culture‐proved cases of Moraxella keratitis from hospital records during a 10‐year period (from December 1995 to November 2005) at the Corneal Unit of the Royal Victorian Eye and Ear Hospital, Melbourne, Australia. Results 95 episodes of Moraxella keratitis were identified in 92 patients. 3 (3.2%) patients had recurrent keratitis. The mean age of the patients was 70 (range 17–93) years. Multiple predisposing factors were identified in 23 (24%) eyes, including corneal graft (n = 15), previous herpes keratitis (n = 15) and eye lid diseases (n = 15). Adjunctive procedures were carried out in 42 eyes. These included botulinum toxin injection (n = 17), tarsorraphy (n = 12), penetrating keratoplasty (n = 8), enucleation (n = 3), tissue adhesive and bandage contact lens (n = 4), and conjunctival flap (n = 5). Polymicrobial infection was present in 17 eyes. Final visual acuity was counting finger or less in 25 (26%) eyes. Conclusions Local ocular predisposing factors play a major role in Moraxella keratitis. This infection has a poor visual outcome attributable to both the nature of the infection and the predisposing factors. PMID:16825274

Pulmonary sequestration (PS) is a rare congenital abnormality of lung tissue. Only few series of adult cases are reported. The aim was to describe clinical characteristics in adult cases of PS and to compare outcomes in different clinical situations. Using MSD engine we searched for cases of PS that have been diagnosed between Jan 1st, 2005 and Dec 31st, 2015. Clinical data was retrospectively gathered. Statistica v.12 (StatSoft, Inc.) was used for statistical analyses. We found 25 cases (18 females, 7 males), which underwent surgery and were histologically proven. There were 22 cases of intralobar PS. 7 cases were asymptomatic, 12 had infectious history (including 3 cases of lung abscess and pleural empyema), 4 presented with hemoptysis, 2 with chest pain. The average age to undergo surgery was 38.24, in the asymptomatic group 34, in symptomatic 39.89. In the latter the symptoms preceded the surgery for 2.45-year. Great majority of sequestrations was located in lower lobes (96%), 52% on the left. Symptomatic cases were at higher than expected risk of surgical complications, comparing to asymptomatic (chi 2 , P=0.04). In most cases there were surgical and histological signs of infection, only in 9 cases etiological factor was determined: in 5 cases it was A. fumigatus . A 0.53-day longer post-surgical hospital stay was observed in the symptomatic group, no statistical significance was found (U-test, P=0.45). Surgical treatment of symptomatic cases of PS is characterized by slightly longer post-surgical hospital stay and higher risk of surgical complications. Fungal infections are the most likely to occur in PS.

After observing persistently low CD4 counts at initial HIV diagnosis in South Africa, we sought to determine risk factors for late-stage HIV disease presentation among adults. We surveyed adults prior to HIV testing at four outpatient clinics in Durban from August 2010 to November 2011. All HIV-infected adults were offered CD4 testing, and late-stage HIV disease was defined as a CD4 count <100 cells/mm(3). We used multivariate regression models to determine the effects of sex, emotional health, social support, distance from clinic, employment, perceived barriers to receiving healthcare, and foregoing healthcare to use money for food, clothing, or housing ("competing needs to healthcare") on presentation with late-stage HIV disease. Among 3,669 adults screened, 830 were enrolled, newly-diagnosed with HIV and obtained a CD4 result. Among those, 279 (33.6%) presented with late-stage HIV disease. In multivariate analyses, participants who lived ≥5 kilometers from the test site [adjusted odds ratio (AOR) 2.8, 95% CI 1.7-4.7], reported competing needs to healthcare (AOR 1.7, 95% CI 1.2-2.4), were male (AOR 1.7, 95% CI 1.2-2.3), worked outside the home (AOR 1.5, 95% CI 1.1-2.1), perceived health service delivery barriers (AOR 1.5, 95% CI 1.1-2.1), and/or had poor emotional health (AOR 1.4, 95% CI 1.0-1.9) had higher odds of late-stage HIV disease presentation. Independent risk factors for late-stage HIV disease presentation were from diverse domains, including geographic, economic, demographic, social, and psychosocial. These findings can inform various interventions, such as mobile testing or financial assistance, to reduce the risk of presentation with late-stage HIV disease.

Lymphogranuloma Venereum 2015: Clinical Presentation, Diagnosis, and Treatment.

PubMed

Stoner, Bradley P; Cohen, Stephanie E

2015-12-15

Lymphogranuloma venereum (LGV) has emerged as an important cause of proctitis and proctocolitis in men who have sex with men; classical inguinal presentation is now increasingly uncommon. We report summary findings of an extensive literature review on LGV clinical presentation, diagnosis, and treatment that form the evidence base for the 2015 Centers for Disease Control and Prevention treatment guidelines for sexually transmitted diseases. Proctitis and proctocolitis are now the most commonly reported clinical manifestations of LGV, with symptoms resembling those of inflammatory bowel disease. Newer molecular tests to confirm LGV infection are sensitive and specific, but are generally restricted to research laboratory or public health settings. Doxycycline (100 mg twice daily for 21 days) remains the treatment of choice for LGV. Patients with rectal chlamydial infection and signs or symptoms of proctitis should be tested for LGV, or if confirmatory testing is not available, should be treated empirically with a recommended regimen to cover LGV infection. © The Author 2015.

This study investigated personality traits and defense styles in order to determine clinical specificities and predictive factors of alcohol use disorders (AUDs) in women. A female sample, composed of AUD outpatients (n = 48) and a control group (n = 50), completed a sociodemographic self-report and questionnaires assessing personality traits (BFI), defense mechanisms and defense styles (DSQ-40). Comparative and correlational analyses, as well as univariate and multivariate logistic regressions, were performed. AUD women presented with higher neuroticism and lower extraversion and conscientiousness. They used less mature and more neurotic and immature defense styles than the control group. Concerning personality traits, high neuroticism and lower conscientiousness were predictive of AUD, as well as low mature, high neurotic, and immature defense styles. Including personality traits and defense styles in a logistic model, high neuroticism was the only AUD predictive factor. AUD women presented clinical specificities and predictive factors in personality traits and defense styles that must be taken into account in AUD studies. Implications for specific treatment for women are discussed.

To identify risk factors associated with suicide of patients with schizophrenia and provide clinical recommendations, which integrate research findings into a consensus based on clinical experience and evidence. A task force formed of experts and clinicians iteratively developed consensus through serial revisions using the Delphi method. Initial survey items were based on systematic literature review published up to June 2013. Various risk factors were reported to be implicated in suicide in schizophrenia. Our findings indicate that suicide risk in schizophrenia is mainly related to affective symptoms, history of a suicide attempt and number of psychiatric admissions. Other risk factors identified are given by younger age, closeness to illness onset, older age at illness onset, male sex, substance abuse and period during or following psychiatric discharge. Integrating the evidence and the experience of the task force members, a consensus was reached on 14 clinical recommendations. Identification of risk factors for suicide in individuals diagnosed with schizophrenia is imperative to improve clinical management and develop strategies to reduce the incidence of suicide in this population. This study provides the critical overview of available data and clinical recommendations on recognition and management of the above-mentioned risk factors. © 2014 John Wiley & Sons A/S.

Risk and protective factors in the clinical rehabilitation of chronic back pain

Wippert, Pia-Maria; Fliesser, Michael; Krause, Matthias

2017-01-01

Objectives Chronic back pain (CBP) can lead to disability and burden. In addition to its medical causes, its development is influenced by psychosocial risk factors, the so-called flag factors, which are categorized and integrated into many treatment guidelines. Currently, most studies investigate single flag factors, which limit the estimation of individual factor significance in the development of chronic pain. Furthermore, factors concerning patients’ lifestyle, biography and treatment history are often neglected. Therefore, the objectives of the present study are to identify commonly neglected factors of CBP and integrate them into an analysis model comparing their significance with established flag factors. Methods A total of 24 patients and therapists were cross-sectionally interviewed to identify commonly neglected factors of CBP. Subsequently, the impact of these factors was surveyed in a longitudinal study. In two rehabilitation clinics, CBP patients (n = 145) were examined before and 6 months after a 3-week inpatient rehabilitation. Outcome variables, chronification factor pain experience (CF-PE) and chronification factor disability (CF-D), were ascertained with confirmatory factor analysis (CFA) of standardized questionnaires. Predictors were evaluated using stepwise calculations of simple and multiple regression models. Results Through interviews, medical history, iatrogenic factors, poor compliance, critical life events (LEs), social support (SS) type and effort–reward were identified as commonly neglected factors. However, only the final three held significance in comparison to established factors such as depression and pain-related cognitions. Longitudinally, lifestyle factors found to influence future pain were initial pain, physically demanding work, nicotine consumption, gender and rehabilitation clinic. LEs were unexpectedly found to be a strong predictor of future pain, as were the protective factors, reward at work and perceived SS

Perceptions of Israeli student nurses regarding clinical specialties and factors that influence these perceptions.

2006-10-01

This paper reports a study to determine the perceptions of baccalaureate nursing students towards clinical specialties and what factors influenced these perceptions. Previous studies have shown that nursing students enter their professional education with preconceived perceptions about the different clinical specialties in nursing. Some investigators have found that factors such as clinical experience influence these perceptions, but others have not. Cultural and social influences, especially among non-western cultures, have rarely been investigated. Israeli baccalaureate nursing students were surveyed in their first, third and fourth years of study during the years 1998-2004. They were asked to rank their preferences for clinical areas related to social need, social prestige, level of interest in the clinical area, job choice and what factors influenced their decisions related to job choice. Mean ranks and associations between class and calendar year cohorts were calculated. Critical care was consistently ranked as the highest preference in all perception checklists, followed by emergency, maternity and paediatric nursing. Psychiatric, community and gerontological nursing were consistently found at the bottom of the list. High levels of association were found among students from different class cohorts and calendar years. Life experiences were ranked as the factor that most influenced career choice. Nursing students in Israel tend to perceive clinical areas in ways similar to other students around the world. These perceptions are strongly influenced by personal experiences and other personal contacts, most often not nursing instructors. Major changes in the local society seem for the most part to have little impact on these perceptions. Therefore there is a need for international nurse educators and recruiters to develop new, creative strategies to encourage nursing students to pursue careers in areas presently considered less popular.

Ntali, Georgia; Wass, John A

2018-04-01

Non-functioning pituitary adenomas (NFPAs) are benign pituitary neoplasms that do not cause a hormonal hypersecretory syndrome. An improved understanding of their epidemiology, clinical presentation and diagnosis is needed. A literature review was performed using Pubmed to identify research reports and clinical case series on NFPAs. They account for 14-54% of pituitary adenomas and have a prevalence of 7-41.3/100,000 population. Their standardized incidence rate is 0.65-2.34/100,000 and the peak occurence is from the fourth to the eighth decade. The clinical spectrum of NFPAs varies from being completely asymptomatic to causing significant hypothalamic/pituitary dysfunction and visual field compromise due to their large size. Most patients present with symptoms of mass effect, such as headaches, visual field defects, ophthalmoplegias, and hypopituitarism but also hyperprolactinaemia due to pituitary stalk deviation and less frequently pituitary apoplexy. Non-functioning pituitary incidentalomas are found on brain imaging performed for an unrelated reason. Diagnostic approach includes magnetic resonance imaging of the sellar region, laboratory evaluations, screening for hormone hypersecretion and for hypopituitarism, and a visual field examination if the lesion abuts the optic nerves or chiasm. This article reviews the epidemiology, clinical behaviour and diagnostic approach of non-functioning pituitary adenomas.

Aim of investigation Hemicrania continua (HC) is an uncommon primary headache and little is known of the characteristics of such patients managed in an orofacial pain setting. This study provides clinical features of HC, its association with other disorders, and treatment outcomes of patients managed in the TMD and Orofacial Pain Clinic at the University of Minnesota. Methods A retrospective review of patient records was undertaken. Inclusion criteria were a diagnosis of HC and confirmation at follow-up. Results Six of the 1617 new patients seen between 2015 and 2017 met the selection criteria. Four patients presented with "facial pain", one with "toothache" and one with "jaw pain". All were female with mean age 55 ± 10.5 years (range = 41-69). Headache characteristics included unilateral (R:L = 1:1) pain of moderate intensity with severe exacerbations in the distribution of V 1 (1/6), V 1  + V 2 (3/6) and V 1  + V 2  + V 3 (2/6). Lacrimation and photophobia were the most common associated symptoms. Patient presentations were complicated by multiple medical and comorbid diagnoses. All were diagnosed with temporomandibular disorder (TMD). Indomethacin alone was sufficient for adequate headache control in 2/6 patients with several add-on medications providing sustained pain relief. Conclusions Comorbid pain conditions can be expected in patients with HC presenting to orofacial pain clinics. Symptom presentation varies, and multimodal treatment approach is necessary for success.

Obstetric fistula is a worldwide problem that is devastating for women in developing countries. The cardinal cause of obstetric fistula is prolonged obstructed labour and delay in seeking emergency obstetric care. Awareness about obstetric fistula is still low in developing countries. The objective was to assess the awareness about risk factors of obstetric fistulae in rural communities of Nabitovu village, Iganga district, Eastern Uganda. A qualitative study using focus group discussion for males and females aged 18-49 years, to explore and gain deeper understanding of their awareness of existence, causes, clinical presentation and preventive measures for obstetric fistula. Data was analyzed by thematic analysis. The majority of the women and a few men were aware about obstetric fistula, though many had misconceptions regarding its causes, clinical presentation and prevention. Some wrongly attributed fistula to misuse of family planning, having sex during the menstruation period, curses by relatives, sexually transmitted infections, rape and gender-based violence. However, others attributed the fistula to delays to access medical care, induced abortions, conception at an early age, utilization of traditional birth attendants at delivery, and some complications that could occur during surgical operations for difficult deliveries. Most of the community members interviewed were aware of the risk factors of obstetric fistula. Some respondents, predominantly men, had misconceptions/myths about risk factors of obstetric fistula as being caused by having sex during menstrual periods, poor usage of family planning, being a curse.

In the United Kingdom, pharmacist and nurse independent prescribers are responsible for both the clinical assessment of and prescribing for patients. Prescribing is a complex skill that entails the application of knowledge, skills, and clinical reasoning to arrive at a clinically appropriate decision. Decision-making is influenced and informed by many factors. This study, the first of its kind, explores what factors influence pharmacist and nurse independent prescribers during the process of clinical reasoning. A think-aloud methodology immediately followed by a semi-structured interview was conducted with 11 active nurse and 10 pharmacist independent prescribers working in secondary care. Each participant was presented with validated clinical vignettes for the think-aloud stage. Participants chose the clinical therapeutic areas for the vignettes, based on their self-perceived competencies. Data were audio-recorded, transcribed verbatim, and a constant-comparative approach was used for analysis. Influences on clinical reasoning were broadly categorised into themes: social interaction, intrinsic, and contextual factors. These themes showed that intrinsic, sociocultural, and contextual aspects heavily influenced the clinical reasoning processes of prescribers. For example, prescribers were aware of treatment pathways, but chose to refer patient cases to avoid making the final prescribing decision. Exploration of this behaviour in the interviews revealed that previous experience and attitudes such as confidence and cautiousness associated with responsibility were strong influencers within the decision-making process. In addition, strengthening the professional identity of prescribers could be achieved through collaborative work with interprofessional healthcare teams to orient their professional practice from within the profession. Findings from this study can be used to inform the education, training, and practice of independent prescribers to improve healthcare

Health profession students develop practical skills whilst integrating theory with practice in a real world environment as an important component of their training. Research in the area of practice placements has identified challenges and barriers to the delivery of effective placement learning. However, there has been little research in podiatry and the question of which factors impact upon clinical educators' capacity to engage with the role remains an under-researched area. This paper presents the second phase of an action research project designed to determine the factors that impact upon clinical educators' capacity to engage with the mentorship role. An online survey was developed and podiatry clinical educators recruited through National Health Service (NHS) Trusts. The survey included socio-demographic items, and questions relating to the factors identified as possible variables influencing clinical educator capacity; the latter was assessed using the 'Clinical Educator Capacity to Engage' scale (CECE). Descriptive statistics were used to explore demographic data whilst the relationship between the CECE and socio-demographic factors were examined using inferential statistics in relation to academic profile, career profile and organisation of the placement. The survey response rate was 42 % (n = 66). Multiple linear regression identified four independent variables which explain a significant proportion of the variability of the dependent variable, 'capacity to engage with clinical education', with an adjusted R2 of 0.428. The four variables were: protected mentorship time, clinical educator relationship with university, sign-off responsibility, and volunteer status. The identification of factors that impact upon clinical educators' capacity to engage in mentoring of students has relevance for strategic planning and policy-making with the emphasis upon capacity-building at an individual level, so that the key attitudes and characteristics that are linked

Objective: to investigate the association of risk factors with the Risk for aspiration nursing diagnosis and respiratory aspiration. Method: cross-sectional study assessing 105 patients with stroke. The instrument used to collect data addressing sociodemographic information, clinical variables and risk factors for Risk for aspiration. The clinical judgments of three expert RNs were used to establish the diagnosis. The relationship between variables and strength of association using Odds Ratio (OR) was verified both in regard to Risk for aspiration and respiratory aspiration. Results: risk for aspiration was present in 34.3% of the patients and aspiration in 30.5%. The following stood out among the risk factors: Dysphagia, Impaired or absent gag reflex, Neurological disorders, and Impaired physical mobility, all of which were statistically associated with Risk for aspiration. Note that patients who develop such a diagnosis were seven times more likely to develop respiratory aspiration. Conclusion: dysphagia, Impaired or absent gag reflex were the best predictors both for Risk for aspiration and respiratory aspiration. PMID:26039291

To describe the clinical features and presentations of perinatal stroke in a prospective and retrospective cohort of Saudi children and ascertain the risk factors. Patients with perinatal stroke were identified from within a cohort of 104 Saudi children who were evaluated at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Saudi Arabia from July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Neuroimaging for suspected cases of stroke consisted of cranial CT, MRI, or both. During the study period, 23 (22%) of 104 children (aged one month to 12 years) were diagnosed to have had perinatal stroke. The male:female ratio was 1.6:1. Ten (67%) of the 15 children who had unilateral ischemic involvement had their lesion in the left hemisphere. The presentation of the ischemic result was within 24-72 hours of life in 13 (57%) patients, and in 6 children (26%), motor impairment was recognized at or after the age of 4 months. Nine children (39%) had seizures at presentation. Pregnancy, labour, and delivery risk factors were ascertained in 18 (78%) cases. The most common of these included emergency cesarean section in 5 cases, and instrumental delivery in another 5. Screening for prothrombotic risk factors detected abnormalities in 6 (26%) patients on at least one test carried out between 2 months and 9 years of age. Four children (17%) had low protein C, which was associated with low protein S and raised anticardiolipin antibodies (ACA) in one patient, and low antithrombin III in another. Low protein S was detected in a 42-month-old boy. The abnormality in the sixth child was confined to raised ACA. The present study highlights the non-specific features by which stroke presents during the neonatal period. The data are in keeping with the potential role for inherited and acquired thrombophilia as being the underlying cause. However, the high prevalence of

Facilitating and obstructing factors for development of learning in clinical practice: a student perspective.

PubMed

Löfmark, A; Wikblad, K

2001-04-01

The aim of this study was to provide information on what the student nurses found facilitating and obstructing for their learning during clinical practice. Earlier studies of experiences of learning in clinical practice have shown that factors as the possibilities of variations of experiences, the culture of the workplace, and communication between the educational institution and health care facilities are of importance. Less is known about the opportunities which students are given in order to practise the skills that they will be expected to perform as new graduate nurses. The experiences of 47 degree student nurses from two colleges in Sweden were gathered in weekly diaries during their final period of clinical practice. A content analysis technique was used to analyse their diaries. The students emphasized responsibility and independence, opportunities to practise different tasks, and receiving feedback as facilitating factors. Other perceived promoting factors included perceptions of control of the situation and understanding of the 'total picture'. Examples of obstructing factors were the nurses as supervisors not relying on the students, supervision that lacked continuity and lack of opportunities to practise. Perception of their own insufficiency and low self-reliance were drawbacks for some students. Recommended proposals are presented to lecturers and supervising staff concerning organizational and educational changes, and changes of attitudes for elucidating the students' experiences of different facilitating and obstructing factors. Changes may contribute to making easier the students' transition into the nursing profession.

Temporomandibular disorder (TMD) patients might present a number of concurrent clinical diagnoses that may be clustered according to their similarity. Profiling patients' clinical presentations can be useful for better understanding the behavior of TMD and for providing appropriate treatment planning. The aim of this study was to simultaneously classify symptomatic patients diagnosed with a variety of subtypes of TMD into homogenous groups based on their clinical presentation and occurrence of comorbidities. Clinical records of 357 consecutive TMD patients seeking treatment in a private specialized clinic were included in the study sample. Patients presenting multiple subtypes of TMD diagnosed simultaneously were categorized according to the AAOP criteria. Descriptive statistics and two-step cluster analysis were used to characterize the clinical presentation of these patients based on the primary and secondary clinical diagnoses. The most common diagnoses were localized masticatory muscle pain (n = 125) and disc displacement without reduction (n = 104). Comorbidity was identified in 288 patients. The automatic selection of an optimal number of clusters included 100% of cases, generating an initial 6-cluster solution and a final 4-cluster solution. The interpretation of within-group ranking of the importance of variables in the clustering solutions resulted in the following characterization of clusters: chronic facial pain (n = 36), acute muscle pain (n = 125), acute articular pain (n = 75) and chronic articular impairment (n = 121). Subgroups of acute and chronic TMD patients seeking treatment can be identified using clustering methods to provide a better understanding of the clinical presentation of TMD when multiple diagnosis are present. Classifying patients into identifiable symptomatic profiles would help clinicians to estimate how common a disorder is within a population of TMD patients and understand the probability of certain

Mutations in mitochondrial DNA (mtDNA) associate with various disease states. A few mtDNA mutations strongly associate with diabetes, with the most common mutation being the A3243G mutation in the mitochondrial DNA-encoded tRNA(Leu,UUR) gene. This article describes clinical characteristics of mitochondrial diabetes and its molecular diagnosis. Furthermore, it outlines recent developments in the pathophysiological and molecular mechanisms leading to a diabetic state. A gradual development of pancreatic beta-cell dysfunction upon aging, rather than insulin resistance, is the main mechanism in developing glucose intolerance. Carriers of the A3243G mutation show during a hyperglycemic clamp at 10 mmol/l glucose a marked reduction in first- and second-phase insulin secretion compared with noncarriers. The molecular mechanism by which the A3243G mutation affects insulin secretion may involve an attenuation of cytosolic ADP/ATP levels leading to a resetting of the glucose sensor in the pancreatic beta-cell, such as in maturity-onset diabetes of the young (MODY)-2 patients with mutations in glucokinase. Unlike in MODY2, which is a nonprogressive form of diabetes, mitochondrial diabetes does show a pronounced age-dependent deterioration of pancreatic function indicating involvement of additional processes. Furthermore, one would expect that all mtDNA mutations that affect ATP synthesis lead to diabetes. This is in contrast to clinical observations. The origin of the age-dependent deterioration of pancreatic function in carriers of the A3243G mutation and the contribution of ATP and other mitochondrion-derived factors such as reactive oxygen species to the development of diabetes is discussed.

To assess epidemiologic characteristics, clinical and pathologic patterns of presentation, and treatment strategies in a contemporary population with renal masses (RMs). The Clinical Research Office of the Endourological Society collected prospective epidemiologic, clinical, and pathologic data on consecutive patients with RMs who were treated during a 1-year period in 98 centers worldwide. Preoperative assessment and treatment were performed according to local clinical practice guidelines. From January 2010 to February 2012, 4288 patients (4355 cases, 4815 tumors) were treated for a RM. The mean age of the cohort was 61.5 years, and the ratio male:female 1.8:1. Caucasians represented 75% of the population, and the median body mass index was 27. The cohort exhibited a high rate of comorbidity (65.6%), including a 48.5% rate of hypertension; one-third of patients had a combination of two or more comorbidities. One-third of patients (36%) had risk factors for renal-cell carcinoma (RCC), of which smoking and obesity were the most common. Diagnosis was incidental in 67% of cases, and 22.2% of cases had chronic kidney disease stage ≥III at presentation. Median radiologic size was 44 mm (range 2-300 mm) and 68% were cT1. Radical nephrectomy and nephron-sparing surgery (NSS) including ablation were performed in 52% and 46% of cases, respectively, while 3.6% of cases were actively surveyed. Median pathologic size was 43 mm (range 2-300 mm) and 63% of the RCCs were pT1. Current patterns of presentation of RMs are consistent with the decreasing trends in age and clinical or pathologic size and increasing incidental diagnosis. Patients exhibit a considerable basal comorbidity and presence of risk factors for RCC. Half of the cases are treated by a nephron-sparing modality with an increase in the penetration of NSS techniques in the contemporary urologic practice.

Little is known about the epidemiology and clinical features of esophageal candidiasis (EC) in pediatric AIDS. We therefore investigated the clinical presentation and risk factors of EC in a large prospectively monitored population of HIV-infected children at the National Cancer Institute. We reviewed the records of all HIV-infected children (N = 448) followed between 1987 and 1995 for a history of esophageal candidiasis to characterize the epidemiology, clinical features, therapeutic interventions and outcome of esophageal candidiasis. To understand further the risk factors for EC in pediatric AIDS, we then performed a matched case-control analysis of 25 patients for whom control cases were available. There were 51 episodes of EC documented in 36 patients with 23 male and 13 female patients (0.2 to 17 years; median CD4, count 11/microl), representing a frequency of EC of 8.0%. Concurrent oropharyngeal candidiasis (OPC) was the most common clinical presentation of EC (94%); other signs and symptoms included odynophagia (80%), retrosternal pain (57%), fever (29%), nausea/vomiting (24%), drooling (12%), dehydration (12%), hoarseness (6%) and upper gastrointestinal bleeding (6%). The causative organism documented in 36 episodes (18 from OPC, 17 from endoscopic biopsy and 1 from autopsy) was Candida albicans in all cases. Patients received treatment for EC with amphotericin B (63%), fluconazole (29%), ketoconazole (4%) or itraconazole (1%). A clinical response was documented in all 45 evaluable episodes. In 6 other cases, EC was a final event without contributing to the cause of death. By a conditional logistic regression model for matched data, the best predictor of EC was the presence of prior OPC (P<0.0001), followed by CD4 count and CD4 percentage (P = 0.0002) and use of antibacterial antibiotics (P = 0.0013). The risks associated with low CD4 count were independent of that of prior OPC. EC in pediatric AIDS is a debilitating infection, which develops in the

To study the clinical profile and presentation of children with unilateral cataract. In this hospital-based, observational, cross-sectional study, patients 15 years of age or younger who presented with unilateral cataract were recruited. Cases of cataract secondary to causes such as trauma or uveitis were excluded. Age at detection and presentation, distance from the treatment center, presenting complaints, cataract morphology, and biometry were noted for each case. A total of 76 patients were recruited. Most patients presented with complaints of leukocoria. Persistent fetal vasculature accounted for 27.6% of cases and was the most common identifiable cause of cataract in this study. Subsequently, patients were divided into two groups: no persistent fetal vasculature (control) and persistent fetal vasculature. A male predominance was noted in both groups. The mean age at detection was 27.58 ± 37.02 and 6.17 ± 8.42 months and the mean age at presentation was 55.613 ± 45.21 and 14.83 ± 17.75 months in the control and persistent fetal vasculature groups, respectively. In the persistent fetal vasculature group, a significant difference was noted in the axial length, keratometry, and corneal diameter between the affected and normal eyes (P = .027, .00176, and .0114, respectively). In the control group, this difference was observed only in keratometry readings (P = .0464). The mean distance traveled by patients to reach the treatment center was 211 km. Persistent fetal vasculature is an important and less identified cause of unilateral cataract. A significant delay is noted in the detection and presentation of unilateral cataract.

Cytomegalovirus (CMV) is one of the most frequently encountered opportunistic viral pathogens in renal transplantation. Approximately 60% of transplant recipients will have CMV infection and >20% will develop symptomatic disease. With the advancement of immunosuppression, variation in the occurrence and pattern of infections is possible. We described the incidence, clinical profile, outcome, and risk factors for development of CMV disease among renal transplant recipients. We studied patients who underwent transplantation from January 2005-December 2009 admitted for CMV disease. CMV infection was present if the patient had at least 1 of the following: positive early antigen detection in blood or tissues, positive CMV antigenemia, or a 4-fold increase in pretransplantation CMV antibody titer. CMV disease was diagnosed if CMV infection was accompanied by clinical signs and symptoms. Descriptive statistics included measures of central tendency for continuous numerical variables and percentage-frequency distribution for categorical variables z test, Wilcoxon-Mann-Whitney test, and Fisher exact test were used to determine risk factors for CMV disease. About 1502 renal transplantations were done during the study period with mean follow-up of 33.8 months. CMV disease was confirmed in 85 (5.8%) recipients who developed 88 CMV disease episodes. Of the 85 patients who had CMV disease, 55% developed ≤ 3 months posttransplantation. Fever was the most common presenting symptom, 53% had coinfection, and case fatality rate was 11%. Risk factors that were statistically significant in the development of CMV disease were as follows: recipient/donor relationship (P = .0115), CMV donor+/recipient- (P = .004), and recent rejection treatment (P = .0084). Incidence of CMV disease was 5.8% with fever as the most common presenting symptom and 55% developed CMV disease ≤ 3 months posttransplantation. Coinfection occurred in 53% and case fatality rate in 11%. Risk factors for developing

Older adults hospitalized with fragility fractures are at high risk of negative events that can culminate in re-presentations to hospital emergency departments or readmissions to hospital. This systematic review aimed to identify patient, clinical, or hospital-related factors that are identifiable at the index admission and that may be associated with re-presentations to hospital emergency departments or hospital readmissions in older adults following fragility fractures. Four electronic databases (PubMed, CINAHL, Embase, and Scopus) were searched. A suite of search terms identified peer-reviewed English-language articles that examined potential correlates of hospital re-presentation in older adults (mean age ≥ 65 years) who were discharged from hospital following treatment for fragility fractures. A three-stage screening process (titles, abstracts, full text) was conducted by two researchers independently. Participant characteristics, study design, potential correlates examined, analyses, and findings were extracted for studies included in the review. Quality and risk of bias were assessed with the Effective Public Health Practice Project Quality Assessment Tool. The strength of evidence was incorporated into a best evidence synthesis, and meta-analysis was conducted where effect pooling was possible. Eleven of 35 eligible studies were categorized as high quality studies. These studies reported that age, higher Cumulative Illness Rating scores, American Society of Anesthesiologists scores > 3, longer length of stay, male sex, cardiovascular disease, low post-operative hemoglobin, kidney disease, dementia and cancer were factors identified at the index admission that were predictive of subsequent re-presentation to hospital. Age was the only predictor for which pooling of effects across studies was possible: pooling was conducted for re-presentation ≤ 30 days (pooled OR, 1.27; 95 % CI, 1.14-1.43) and > 30 days (pooled OR, 1.23; 95 % CI, 1

To describe factors and outcomes related to the decision-making process regarding participation in a cancer clinical trial. Cross-sectional, descriptive. Urban, academic, National Cancer Institute-designated comprehensive cancer center in the mid-Atlantic United States. 197 patients with advanced gastrointestinal cancer. Mailed survey using one investigator-developed instrument, eight instruments used in published research, and a medical record review. disease context, sociodemographics, hope, quality of life, trust in healthcare system, trust in health professional, preference for research decision control, understanding risks, and information. decision to accept or decline research participation and satisfaction with this decision. All of the factors within the Research Decision Making Model together predicted cancer clinical trial participation and satisfaction with this decision. The most frequently preferred decision-making style for research participation was shared (collaborative) (83%). Multiple factors affect decision making for cancer clinical trial participation and satisfaction with this decision. Shared decision making previously was an unrecognized factor and requires further investigation. Enhancing the process of research decision making may facilitate an increase in cancer clinical trial enrollment rates. Oncology nurses have unique opportunities as educators and researchers to support shared decision making by those who prefer this method for deciding whether to accept or decline cancer clinical trial participation.

Clinical presentation, diagnosis and treatment of vulvovaginitis in girls: a current approach and review of the literature.

Vulvovaginitis is the most common cause of gynecological complaints in children and young girls. Some of the factors which cause vulvovaginitis include hypoestrogenism, the anatomical proximity of rectum and delicate vulvar skin and vaginal mucosa. We made a literature search with Pubmed, Medline and Cochrane database from January 2002 to May 2015 in English language using the key words vulvovaginitis, children, clinical, diagnosis and treatment. Vulvovaginitis in girls is usually caused by non-specific factors and hygiene measures, bioyoghurt and avoidance of chemical irritants are generally useful. Weight control if necessary and prevention of voiding dysfunction are effective. Vaginal flora is important in girls and results should be interpreted with clinical features to decide whether an isolated microorganism is part of the normal microflora or is the cause of symptomatic vulvovaginitis. Specific treatment is generally considered in case of a detected pathogen microorganism. Isolation of a sexually transmitted organism requires further investigation. Persistent disease may not always indicate a foreign body but it must be taken into account. Girls and parents are encouraged psychologically in all steps of evaluation, diagnosis and treatment. Probiotics, nanotechnology and petroleum jelly are other important treatment options used in vulvovaginitis. In this review, we present current approach to the presentation and management of vulvovaginitis in childhood. This disorder requires a comprehensive evaluation in all steps of diagnosis, differential diagnosis and treatment.

Inhaled corticosteroids are anti-inflammatory medications that can down-regulate the immunologic response in patients with COPD; however, their role at onset of COPD exacerbation is still not understood. The aim of this study was to assess the early inflammatory response and clinical presentation of patients with COPD exacerbation mediated by inhaled corticosteroids. Prospective data were collected on 123 hospitalized subjects with COPD exacerbation over a 30-month period at 2 Spanish university hospitals. Based on domiciliary use, comparative analyses were performed between subjects who did not use inhaled corticosteroids (n = 58) and subjects who did (n = 65). Measurements of serum biomarkers were recorded on admission to the hospital (day 1) and on day 3; clinical, physiological, microbiological, and severity data and mortality/readmission rates were also recorded. At days 1 and 3, both groups showed a similar inflammatory response; fluticasone produced lower levels of interleukin-8 compared with budesonide (P < .01). All clinical features considered were similar in the 2 groups; multivariate analysis predicting clinical complications on hospitalization showed air-flow obstruction severity as the only predictive factor (odds ratio 3.13, 95% CI 1.13-8.63, P = .02). Our study demonstrates a lack of inhaled corticosteroid influence in the early systemic inflammatory response to and clinical presentation of COPD exacerbation.

Black raspberries in cancer clinical trials: Past, present and future.

PubMed

Kresty, Laura A; Mallery, Susan R; Stoner, Gary D

Black raspberries (BRB) inhibit a broad range of cancers in preclinical models, including in vivo models of oral, esophageal, colon, breast and skin cancer. Promising preclinical results have led to clinical evaluations in cancer patients or patients at increased risk for cancer development. To summarize clinical investigations targeting cancer or precancerous lesions with BRB and discuss future directions. A thorough literature search was conducted through December 1, 2015 to identify all published studies evaluating BRB in cancer focused clinical trials. Research investigating BRB in clinical settings report positive effects on preneoplastic lesions or cancers of the oral cavity, esophagus and colon. BRB treatment resulted in: histologic regression of oral intraepithelial neoplasia associated with improved histologic grade and significantly reduced loss of heterozygosity at tumor suppressor gene loci, modulated genes linked to RNA processing and growth factor recycling; in the colon, BRB inhibited FAP-associated polyp progression, demethylated tumor suppressor genes and improved plasma cytokine profiles; in Barrett's patients, BRB consumption increased tissue levels of GST-pi and decreased 8-isoprostane, a marker of lipid peroxidation/oxidative stress. The precise dose, duration and optimum mode of BRB delivery for cancer inhibition remains to be fully elucidated. Common themes across studies support that BRB are anti-proliferative, anti- inflammatory, reduce oxidative stress and restore tumor suppressive activity. Future directions are included in the conclusions section.

Correct detection of bone metastases in patients with non-small cell lung cancer (NSCLC) is crucial for prognosis and selection of an appropriate treatment regimen. The aim of this study was to investigate the role of whole-body bone scanning (WBBS) and clinical factors in detecting bone metastases in NSCLC. One hundred twenty-five patients with a diagnosis made between 1998 and 2002 were recruited (squamous cell carcinoma, 54.4%; adenocarcinoma, 32.8%; non-small cell carcinoma, 8.8%; large cell carcinoma, 4%). Clinical factors suggesting bone metastasis (skeletal pain, elevated alkaline phosphatase, hypercalcemia) were evaluated. WBBS was performed in all patients, and additional MRI was ordered in 10 patients because of discordance between clinical factors and WBBS findings. Bone metastases were detected in 53% (n = 21) of 39 clinical factor-positive patients, 5.8% (n = 5) of 86 clinical factor-negative patients, and 20.8% of total patients. The existence of bone-specific clinical factors as indicators of metastasis presented 53.8% positive predictive value (PPV), 94.2% negative predictive value (NPV), and 81.6% accuracy. However, the findings of WBBS showed 73.5% PPV, 97.8% NPV, and 91.2% accuracy. Adenocarcinoma was the most common cell type found in patients with bone metastasis (39%). The routine bone scanning prevented two futile thoracotomies (8%) in 25 patients with apparently operable lung cancer. In spite of the high NPV of the bone-specific clinical factors and the high value obtained in the false-positive findings in the bone scan, the present study indicates that in patients for whom surgical therapy is an option, preoperative staging using WBBS can be helpful to avoid misstaging due to asymptomatic bone metastases.

Clinical Application of Growth Factors and Cytokines in Wound Healing

2016-01-01

Wound healing is a complex and dynamic biological process that involves the coordinated efforts of multiple cell types and is executed and regulated by numerous growth factors and cytokines. There has been a drive in the past two decades to study the therapeutic effects of various growth factors in the clinical management of non-healing wounds (e.g. pressure ulcers, chronic venous ulcers, diabetic foot ulcers). For this review, we conducted a nonline search of Medline and Pub Medical and critically analyzed the literature regarding the role of growth factors and cytokines in the management of these wounds. We focused on currently approved therapies, emerging therapies and future research possibilities. In this review we discuss four growth factors and cytokines currently being used on and off label for the healing of wounds. These include: granulocyte-macrophage colony stimulating factor (GM-CSF), platelet derived growth factor (PDGF), vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF). While the clinical results of using growth factors and cytokines are encouraging, many studies involved a small sample size and are disparate in measured endpoints. Therefore, further research is required to provide definitive evidence of efficacy. PMID:24942811

The repetition of hospital-treated self-harm by young people is common. However, little work has summarised the modifiable factors associated with this. A thorough understanding of those factors most strongly associated with repetition could guide the development of relevant clinical interventions. We systematically reviewed four databases (EMBASE, Medline, PubMed and PsycINFO) until 15 April 2016 to identify all observational studies of factors for the repetition of self-harm or suicide reattempts (together referred to as 'self-harm behaviour') in young people. We quantified the magnitude of association with odds ratios (OR) and 95% confidence intervals (CIs) and calculated the population attributable risk (PAR) and population preventable fraction (PPF) for modifiable factors to provide an indication of the potential impact in reducing subsequent self-harm behaviour in this population. Seventeen studies were included comprising 10,726 participants. Borderline personality disorder (OR 3.47, 95% CI 1.84-6.53; PAR 42.4%), any personality disorder (OR 2.54, 95% CI 1.71-3.78; PAR 16.3%), and any mood disorder (OR 2.16, 95% CI 1.09-4.29; PAR 42.2%) are important modifiable risk factors. Severity of hopelessness (OR 2.95, 95% CI 1.74-5.01), suicidal ideation (OR 2.01, 95% CI 1.43-2.81), and previous sexual abuse (OR 1.52, 95% CI 1.02-2.28; PAR 12.8%) are also associated with repetition of self-harm. We recommend that clinical services should focus on identifying key modifiable risk factors at the individual patient level, whilst the reduction of exposure to child and adolescent sexual abuse would also be a useful goal for public health interventions.

Spinal dural arteriovenous fistula (SDAVF) is a relatively common acquired vascular malformation of the spinal cord. Assessment of a SDAVF is often difficult because of non-specific findings on non-invasive imaging modalities. Diagnosis of a SDAVF is often delayed, and some patients receive unnecessary treatment and treatment delays, often resulting in a poor outcome. The aim of this study was to characterize the clinical presentation, typical imaging findings, and long-term outcome of SDAVF. Forty patients (13 women, 27 men; mean age 58.18 ± standard deviation 14.75 years) who were treated at our hospital from June 1992 to March 2014 were retrospectively reviewed. We investigated the baseline characteristics, clinical presentation, imaging findings, treatment modalities, and outcome of the patients. The most common clinical presentation was a sensory symptom (80%), followed by motor weakness (70%), and sphincter dysfunction (62.5%). Roughly one-third (32.5%) of patients had a stepwise progression of fluctuating weakness and sensory symptoms, but the most common presentation was chronic progressive myelopathic symptoms (47.5%). Thirty-four patients (85%) had T2 signal change on the spinal cord MRI, indicative of cord edema. Thirty-eight patients had typical perimedullary vessel flow voids on T2-weighted MRI. Twenty-eight patients were treated with endovascular embolization, five patients underwent surgery, and four patients underwent both. Clinical outcome was determined by severity of initial deficit (p=0.008), extent of cord edema (p=0.010), treatment failure (p=0.004), and a residual fistula (p=0.017). SDAVF causes a treatable myelopathy, so early diagnosis and intervention is essential. Copyright © 2015 Elsevier Ltd. All rights reserved.

In general, clinical research network capacity building refers to programs aimed at enhancing networks of researchers to conduct clinical research. Although in the literature there is a large body of research on how to develop and build capacity in clinical research networks, the conceptualizations and implementations remain controversial and challenging. Moreover, the experiences learnt from the past accomplishments and failures can assist in the future capacity building efforts to be more practical, effective and efficient. In this paper, we aim to provide an overview of capacity building in clinical research network by (1) identifying the key barriers to clinical research network capacity building, (2) providing insights into how to overcome those obstacles, and (3) sharing our experiences in collaborating with national and international partners to build capacity in clinical research networks. In conclusion, we have provided some insight into how to address the key factors of clinical research network capacity building and shared some empirical experiences. A successful capacity building practice requires a joint endeavor to procure sufficient resources and support from the relevant stakeholders, to ensure its efficiency, cost-effectiveness, and sustainability.

All versions of the Inventory of Interpersonal Problems (IIP) are broadly used to measure people's interpersonal functioning. The aims of the current study are: (a) to examine the psychometric properties and factor structure of the Italian version of the Inventory of Interpersonal Problems-short version (IIP-32); and (b) to evaluate its associations with core symptoms of different eating disorders. One thousand two hundred and twenty three participants ( n = 623 non-clinical and n = 600 clinical participants with eating disorders and obesity) filled out the Inventory of Interpersonal Problems-short version (IIP-32) along with measures of self-esteem (Rosenberg Self-Esteem Scale, RSES), psychological functioning (Outcome Questionnaire, OQ-45), and eating disorders (Eating Disorder Inventory, EDI-3). The present study examined the eight-factor structure of the IIP-32 with Confirmatory Factor Analysis (CFA) and Exploratory Structural Equation Modeling (ESEM). ESEM was also used to test the measurement invariance of the IIP-32 across clinical and non-clinical groups. It was found that CFA had unsatisfactory model fit, whereas the corresponding ESEM solution provided a better fit to the observed data. However, six target factor loadings tend to be modest, and ten items showed cross-loadings higher than 0.30. The configural and metric invariance as well as the scalar and partial strict invariance of the IIP-32 were supported across clinical and non-clinical groups. The internal consistency of the IIP-32 was acceptable and the construct validity was confirmed by significant correlations between IIP-32, RSES, and OQ-45. Furthermore, overall interpersonal difficulties were consistently associated with core eating disorder symptoms, whereas interpersonal styles that reflect the inability to form close relationships, social awkwardness, the inability to be assertive, and a tendency to self-sacrificing were positively associated with general psychological maladjustment

Insight has emerged as a significant treatment outcome predictor in adult obsessive-compulsive disorder (OCD), with some suggesting that OCD with poor insight represents a distinct clinical subtype. Despite its clinical relevance, limited data exist on insight in pediatric OCD patients. The present study investigated the relation between poor insight and clinical characteristics among children and adolescents with OCD (N=78, ages 6-20 years). Forty-five percent of the sample (n=35) was considered to have low levels of insight into their symptoms, as determined by clinician rating on item 11 of the Children's Yale-Brown Obsessive-Compulsive Scale. Pearson product-moment correlations showed a significant, inverse relation between insight and OCD severity. Relative to the high insight group, parents of patients with low insight reported higher levels of OCD-related impairment and family accommodation. These findings suggest that OCD with poor insight may represent a distinct clinical feature that may require more intensive and multimodal treatment approaches.

2002-01-01

A retrospective study of 43 dogs with anal sac adenocarcinoma (ASAC) was performed to characterize the clinical presentation and response to treatment. Clinical signs at presentation varied considerably, with signs related either to sublumbar nodal metastasis (tenesmus or constipation) or hypercalcemia (polyuria-polydipsia and anorexia) being the most frequent findings. At the time of presentation, 23 (53%) dogs had hypercalcemia and 34 (79%) had metastases, with the regional lymph nodes (31 dogs, 72%) being the most common site of metastasis. A variety of chemotherapeutic agents were administered, with partial remission (PR) recorded in 4 of 13 (31%) dogs treated with cisplatin and in 1 of 3 (33%) dogs treated with carboplatin. The median survival for all dogs was 6 months (range, 2 days-41 months). There was no statistical association between the presence of hypercalcemia and survival, although the power of the study to detect an increase in survival of 3 months was low (.33). We conclude that platinum chemotherapy has antitumor activity in canine apocrine gland carcinoma and that further study of these agents is warranted.

Clinical presentations of parvovirus B19 infection.

PubMed

Servey, Jessica T; Reamy, Brian V; Hodge, Joshua

2007-02-01

Although most persons with parvovirus B19 infection are asymptomatic or have mild, nonspecific, cold-like symptoms, several clinical conditions have been linked to the virus. Parvovirus B19 usually infects children and causes the classic "slapped-cheek" rash of erythema infectiosum (fifth disease). The virus is highly infectious and spreads mainly through respiratory droplets. By the time the rash appears, the virus is no longer infectious. The virus also may cause acute or persistent arthropathy and papular, purpuric eruptions on the hands and feet ("gloves and socks" syndrome) in adults. Parvovirus B19 infection can trigger an acute cessation of red blood cell production, causing transient aplastic crisis, chronic red cell aplasia, hydrops fetalis, or congenital anemia. This is even more likely in patients with illnesses that have already shortened the lifespan of erythrocytes (e.g., iron deficiency anemia, human immunodeficiency virus, sickle cell disease, thalassemia, spherocytosis). A clinical diagnosis can be made without laboratory confirmation if erythema infectiosum is present. If laboratory confirmation is needed, serum immunoglobulin M testing is recommended for immunocompetent patients; viral DNA testing is recommended for patients in aplastic crisis and for those who are immunocompromised. Treatment is usually supportive, although some patients may require transfusions or intravenous immune globulin therapy. Most patients recover completely.

Breech presentation: an audit project as means of pursuing clinical excellence.

PubMed

Siassakos, D; Anderson, H; Panter, K

2005-10-01

Clinical audit is an effective quality improvement process to evaluate important clinical issues. Breech presentation is such an issue due to its contribution to the rising caesarean section (CS) rate. We set out to assess the management of breech presentation using, as standards, the delivery suite protocol and national guidelines. Our first audit revealed a low success rate of external cephalic version (ECV) and deficient documentation of written consent for ECV, other aspects of care being satisfactory. The results were presented to a multidisciplinary meeting and disseminated to relevant stakeholders. A re-audit was then performed. It confirmed significant improvement in the documentation of consent for ECV. It also revealed a good detection rate of breech, optimal offer rate of ECV and good neonatal outcome. However, uptake of ECV as well as the success rate could both be improved so as to reduce the CS rate for breech presentation. We discuss options for improving the uptake and success rate for ECV.

1. Chronic wounds, especially in diabetics, represent a serious threat to human health. 2. Correcting a compromised state of tissue oxygenation by the administration of supplemental O(2) is known to benefit wound healing. Beyond its role as a nutrient and antibiotic, O(2) supports wound healing by driving redox signaling. 3. Hyperbaric oxygen (HBO) therapy is widely used and approved by Center for Medicare and Medicaid Services to treat specific ulcerations. The current literature supports the notion that approaches to topically oxygenate wounds may be productive. 4. Here, we present the results of two simultaneous studies testing the effects of HBO and portable topical oxygen (TO) therapies. These two therapeutic approaches have several contrasting features. 5. In total, 1854 patients were screened in outpatient wound clinics for non-randomized enrolments into the HBO (n = 32; 31% diabetic) and TO (n = 25; 52% diabetic) studies. 6. Under the conditions of the present study, HBO treatment seemed to benefit some wounds while not benefiting others. Overall, HBO did not result in statistically significant improvements in wound size in the given population over the time monitored in the present study. 7. However, TO significantly improved wound size. Among the three O(2)-sensitive genes (VEGF, TGFbeta1 and COL1A1) studied in wound edge tissue biopsies, TO treatment was associated with higher VEGF165 expression in healing wounds. Expression of the other genes mentioned was not affected by TO. There was no significant change in the expression levels of any of genes studied in patients in the HBO study. This establishes a link between VEGF gene expression and healing outcome for TO therapy. 8. Taken together, the present study provides evidence demonstrating that TO treatment benefits wound healing in patients suffering from chronic wounds. Treatment with TO is associated with an induction of VEGF expression in wound edge tissue and an improvement in wound size.

Nurse-led clinics for atrial fibrillation: managing risk factors.

Jacob, Liril

2017-12-14

Atrial fibrillation (AF) is the most common and sustained cardiac arrhythmia rated by cardiologists as one of the most difficult conditions to manage. Traditionally, AF management has focused on the three pillars of rate control, rhythm control and anticoagulation. However, more recently, cardiovascular risk-factor management in AF has emerged as a fourth and essential pillar, delivering improved patient outcomes. In the UK, AF is a condition that is often managed poorly, with patients reporting a lack of understanding of their condition and treatment options. Many aspects of assessment and communication in AF management are time consuming. Failure to address those aspects may negatively affect the quality of care. Nurse-led clinics can contribute significantly in the areas of patient education and sustained follow-up care, improving outcomes and addressing current deficiencies in AF risk-factor management due to scarcity of medical resources. This article discusses the major cardiovascular risk factors associated with AF, drawing on evidence from the literature, and considers the effectiveness and implications for practice of introducing community-based nurse-led clinics for risk-factor management in patients with AF.

Background Insomnia frequently occurs to patients with persistent back pain. By worsening pain, mood, and physical functioning, insomnia could lead to the negative clinical consequences of patients with failed back surgery syndrome (FBSS). This retrospective and cross-sectional study aims to identify the risk factors associated with clinical insomnia in FBSS patients. Methods A total of 194 patients with FBSS, who met the study inclusion criteria, were included in this analysis. The Insomnia Severity Index (ISI) was utilized to ascertain the presence of clinical insomnia (ISI score ≥ 15). Logistic regression analysis evaluates patient demographic factors, clinical factors including prior surgical factors, and psychological factors to identify the risk factors of clinical insomnia in FBSS patients. Results After the persistent pain following lumbar spine surgery worsened, 63.4% of patients reported a change from mild to severe insomnia. In addition, 26.2% of patients met the criteria for clinically significant insomnia. In a multivariate logistic regression analysis, high pain intensity (odds ratio (OR) =2.742, 95% confidence interval (CI): 1.022 - 7.353, P =0.045), high pain catastrophizing (OR=4.185, 95% CI: 1.697 - 10.324, P =0.002), greater level of depression (OR =3.330, 95% CI: 1.127 - 9.837, P =0.030) were significantly associated with clinical insomnia. However, patient demographic factors and clinical factors including prior surgical factors were not significantly associated with clinical insomnia. Conclusions Insomnia should be addressed as a critical part of pain management in FBSS patients with these risk factors, especially in patients with high pain catastrophizing.

Background: Clinical reasoning is generally defined as the numerous modes of thinking that guide clinical practice but little is known about the factors affecting how occupational therapists manage the decision-making process. The aim of this qualitative study was to explore the factors influencing the clinical reasoning of occupational therapists. Methods: Twelve occupational therapy practitioners working in mental and physical dysfunction fields participated in this study. The sampling method was purposeful and interviews were continued until data saturation. All the interviews were recorded and transcribed. The data were analyzed through a qualitative content analysis method. Results: There were three main themes. The first theme: socio-cultural conditions included three subthemes: 1- client beliefs; 2- therapist values and beliefs; 3- social attitude to disability. The second theme: individual attributions included two subthemes 1- client attributions; 2- therapist attributions. The final theme was the workplace environment with the three subthemes: 1- knowledge of the managers of rehabilitation services, 2- working in an inter-professional team; 3- limited clinical facilities and resources. Conclusion: In this study, the influence of the attitudes and beliefs of client, therapist and society about illness, abilities and disabilities upon reasoning was different to previous studies. Understanding these factors, especially the socio-cultural beliefs basis can play a significant role in the quality of occupational therapy services. Accurate understanding of these influential factors requires more extensive qualitative and quantitative studies. PMID:25250253

Our aim was to assess if term and preterm infants with volvulus showed different patterns with regard to pathogenesis, clinical presentation and outcome. We reviewed the medical records and imaging data of infants aged less than six months with volvulus treated in a single surgical referral centre from 2006-2013. Volvulus was diagnosed in 19 infants, with no anatomical anomaly in three of the 12 preterm infants and one of the seven term infants. Most cases (74%) presented during the first eight days of life. Later presentations occurred exclusively in preterm infants, with only one of the five having no anatomic anomalies. Bilious vomiting was the leading symptom in six of the seven term infants, while the symptoms in preterm infants were rather nonspecific. Intestinal necrosis, with the need for bowel resection, occurred in one term (14%) infant and nine (75%) preterm infants. The clinical presentation and outcome of volvulus differed between preterm and term infants, but the rate and distribution of underlying anomalies did not differ. Symptoms in preterm infants were often nonspecific and led to a delay in diagnosis. This might have contributed to the higher rate of intestinal necrosis in preterm infants. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

The importance of self-regulated learning (SRL) has been broadly recognised by medical education institutions and regulatory bodies. Supporting the development of SRL skills has proven difficult because self-regulation is a complex interactive process and we know relatively little about the factors influencing this process in real practice settings. The aim of our study was therefore to identify factors that support or hamper medical students' SRL in a clinical context. We conducted a constructivist grounded theory study using semi-structured interviews with 17 medical students from two universities enrolled in clerkships. Participants were purposively sampled to ensure variety in age, gender, experience and current clerkship. The Day Reconstruction Method was used to help participants remember their activities of the previous day. The interviews were transcribed verbatim and analysed iteratively using constant comparison and open, axial and interpretive coding. Self-regulated learning by students in the clinical environment was influenced by the specific goals perceived by students, the autonomy they experienced, the learning opportunities they were given or created themselves, and the anticipated outcomes of an activity. All of these factors were affected by personal, contextual and social attributes. Self-regulated learning of medical students in the clinical environment is different for every individual. The factors influencing this process are affected by personal, social and contextual attributes. Some of these are similar to those known from previous research in classroom settings, but others are unique to the clinical environment and include the facilities available, the role of patients, and social relationships pertaining to peers and other hospital staff. To better support students' SRL, we believe it is important to increase students' metacognitive awareness and to offer students more tailored learning opportunities. © 2015 John Wiley & Sons Ltd.

A Method to Evaluate Critical Factors for Successful Implementation of Clinical Pathways.

PubMed

Dong, W; Huang, Z

2015-01-01

Clinical pathways (CPs) have been viewed as a multidisciplinary tool to improve the quality and efficiency of evidence-based care. Despite widespread enthusiasm for CPs, research has shown that many CP initiatives are unsuccessful. To this end, this study provides a methodology to evaluate critical success factors (CSFs) that can aid healthcare organizations to achieve successful CP implementation. This study presents a new approach to evaluate CP implementation CSFs, with the aims being: (1) to identify CSFs for implementation of CPs through a comprehensive literature review and interviews with collaborative experts; (2) to use a filed study data with a robust fuzzy DEMATEL (the decision making trial and evaluation laboratory) approach to visualize the structure of complicated causal relationships between CSFs and obtain the influence level of these factors. The filed study data is provided by ten clinical experts of a Chinese hospital. 23 identified CSF factors which are initially identified through a review of the literature and interviews with collaborative experts. Then, a number of direct and indirect relationships are derived from the data such that different perceptions can be integrated into a compromised cause and effect model of CP implementation. The results indicate that the proposed approach can systematically evaluate CSFs and realize the importance of each factor such that the most common causes of failure of CP implementation could be eliminated or avoided. Therefore, the tool proposed would help healthcare organizations to manage CP implementation in a more effective and proactive way.

Leprosy is a disease of declining global endemicity but is still an important health-care problem in India. Pure neural leprosy is an important subset of presentations of leprosy in India. Leprosy is a known disease of the skin and nerves, but cases of pure neural involvement are relatively less. We hereby present 10 cases of pure neural leprosy in which the diagnosis of leprosy was difficult with routine methods. The study was conducted at the main referral center and satellite clinics of our organization. A retrospective analysis of patient records for the last four years was undertaken to identify patients presenting with predominantly neurological manifestations and uncommon presentations including those without skin lesions. The medical records of the patients were used as source of data. All the patients were subjected to a detailed clinical examination and bacteriological examination with slit-skin smears. Investigations like nerve biopsy, electromyography, and nerve conduction studies were done in patients with diagnostic difficulties. Patients presented with neurological symptoms like paresthesias (60%), diminished sensations (40%), nonhealing ulcers (30%), and blisters (20%). All except one had thickened nerves on clinical examination. Slit-skin smear was negative in all but one patient. Nerve biopsy confirmed the diagnosis of leprosy in seven cases. Pure neural leprosy is difficult to diagnose with routine methods. The diagnosis should be considered, especially by neurologists and dermatologists, who are more likely to see such patients with predominant neural manifestations. The diagnosis should be confirmed with nerve biopsy to prevent delay in therapy and associated complications.

The objective of this study was to determine the prevalence of and factors associated with clinical and perceived oral malodor among dental students. Clinical oral malodor was measured in 163 Malaysian dental students using organoleptic method and Oral ChromaTM and they were asked about their perception of self-oral malodor. Oral examination was performed to assess oral health status. Statistical analyses were performed using SPSS version 19.0. There were 52.7% students who had clinical oral malodor, while 19.0% students perceived they had oral malodor. The sensitivity (0.244) of self-perceived oral malodor was lower than its specificity (0.870). Tongue coating was closely associated with clinical oral malodor whereas high plaque index was closely associated with perceived oral malodor. These results showed that clinical oral malodor was prevalent among dental students, but students' perception of oral malodor did not always reflect actual clinical oral malodor. Furthermore, associating factors of clinical oral malodor differ from perceived oral malodor. The importance of controlling clinical oral malodor with proper tongue cleaning should be emphasized and dental students should be taught on the differences between clinical and perceived oral malodor in order to manage this problem.

Gangliogliomas are rare tumors composed of an admixture of glial and neuronal components. These usually occur in young patients, who present with therapy-resistant seizures. Clinical presentation of ganglioglioma with diabetes insipidus is extremely rare with only one case reported earlier in the available literature. Due to this rarity, ganglioglioma is not considered in the differential diagnosis in a patient with diabetes insipidus. A 7-year boy presented with polyuria, polydipsia, and progressive visual loss for 18 months. Investigations revealed diabetes insipidus. Radiographic studies of the brain showed a solid and cystic mass in the suprasellar region effacing the third ventricle. Intraoperatively, diffuse thickening of bilateral optic nerves and optic chiasma was noted and a diagnosis of optic glioma was considered. A biopsy of the mass was taken, which on histopathological examination showed features of ganglioglioma. The patient was referred for further radiotherapy but was lost to follow-up. Diabetes insipidus as a presenting symptom of ganglioglioma is extremely rare. This benign tumor should be kept in mind in patients with central diabetes insipidus and a suprasellar mass lesion. This report describes the second such case in the literature.

Pneumocystis jirovecii pneumonia (PCP) can occur in HIV patients but also in those without HIV (non-HIV PCP) but with other causes of immunodeficiency including malignancy or rheumatic diseases. To evaluate the clinical presentation and prognostic factors of non-HIV PCP, we retrospectively reviewed all patients diagnosed as having PCP without HIV at Kameda Medical Center, Chiba, Japan, from January 2005 until June 2012. For the purpose of examining a prognostic factor for non-HIV PCP with 30-day mortality, we compared the characteristics of patients, clinical symptoms, radiological images, Eastern Cooperative Oncology Group performance status (PS), and the time from the onset of respiratory symptoms to the start of therapy, in both survival and fatality groups. A total of 38 patients were eligible in this study. Twenty-five survived and 13 had died. The non-HIV PCP patients in the survivor group had a better PS and received anti-PCP therapy earlier than those in the nonsurvivor group. Rales upon auscultation and respiratory failure at initial visits were seen more frequently in the nonsurvivor group than in the survivor group. Lactate dehydrogenase and C-reactive protein values tended to be higher in the nonsurvivor group, but this was not statistically significant. Multivariate analyses using 5 variables showed that a poor PS of 2-4 was an independent risk factor for non-HIV PCP patients and resulted in death (odds ratio 15.24; 95% confidence interval 1.72-135.21). We suggest that poor PS is an independent risk factor in non-HIV PCP, and a patient's PS and disease activity may correlate with outcome. © 2017 S. Karger AG, Basel.

Background : Pneumonia is a major complication of influenza that contributes to mortality. Clinical characteristics and factors of influenza virus contributing to the severity and mortality of pneumonia have not been fully elucidated. Objective : The objective was to clarify clinical characteristics and factors contributing to the severity and mortality of influenza-associated pneumonia ( flu-p ). Methods : We retrospectively analyzed patients with flu-p . Results : From December 1999 to March 2016, 210 patients with a median age of 69 (range, 17 to 92) years with flu-p based on positive rapid antigen tests, increased antibody titers of paired sera, or positive results of reverse transcription polymerase chain reaction were admitted to our institution. A multivariate analysis found that advanced age (≥ 65 years), pneumonia subtypes (unclassified), diabetes mellitus, and acute kidney injury complicated with flu-p were independent factors associated with disease severity, whereas pneumonia subtypes (mixed viral and bacterial pneumonia and unclassified), healthcare-associated pneumonia, acute kidney injury complicated with flu-p , and severity on admission (severe) were independent factors associated with non-survival. Conclusion : The clinical characteristics of flu-p are varied, and the contribution of several factors to the severity and mortality of flu-p suggest their importance in either preventing flu-p or managing flu-p after it develops.

Severe congenital factor VII (FVII) deficiency is a rare bleeding disorder. Prophylaxis with replacement therapy has been suggested to patients, yet the most beneficial dosing regimens and therapy intervals are still to be defined. Due to the lack of evidence-based data, we hereby present our experience with long-term administration and monitoring primary prophylaxis in children with severe FVII deficiency and an extremely high bleeding risk. Four children with familial FVII deficiency, treated by prophylactic recombinant activated factor VII (rFVIIa), 15-30μg/kg/dose, given 2-3 times weekly since infancy, are discussed. Clinical follow up and monitoring laboratory assays, including thrombin generation, measured at various time points after prophylactic rFVIIa administration are presented. Among our treated patients neither FVII activity nor thrombin generation parameters (both already declined 24h post rFVIIa administration) were able to predict the impact of prophylaxis, and could not be used as surrogate markers in order to assess the most beneficial treatment frequency. However, the long clinical follow-up and comprehensive laboratory assessment performed, have shown that early primary prophylaxis as administered in our cohort was safe and effective.

To evaluate the use of plasma Placental Growth Factor (PlGF), recommended by the recent NICE guidance, in women with suspected pre-eclampsia (PE) and/or fetal growth restriction (FGR). Non-randomised prospective clinical evaluation study in high-risk antenatal clinics in a tertiary maternity unit. PlGF testing was performed in addition to routine clinical assessment in 260 women >20 weeks' gestation with chronic disease (hypertension, renal disease ± diabetes) with a change in maternal condition or in women with suspected FGR to determine the impact on clinical management. Results were revealed and standardised care pathways followed. Outcome of pregnancies with a low PlGF (<12 pg/ml and 13-100 pg/ml), impact on clinical service and the diagnostic accuracy of alternative PlGF cut-offs. 206/260 (79.2%) women had an adverse outcome (PE/birthweight < 10th centile/preterm birth). In our cohort, a low PlGF (<12 pg/ml) was associated with a shorter test-birth interval and universally (100% PPV) with an adverse pregnancy outcome, although 29/61 (47.5%) of women with PlGF < 12 pg/ml continued their pregnancy >14 days. The PlGF result altered clinical management (surveillance or timing of birth) in 196/260 (75.4%) cases. Alternative PlGF thresholds did not significantly improve diagnostic performance. Our evaluation confirms the value of PlGF as a diagnostic tool for placental dysfunction. However, low PlGF in isolation should not trigger iatrogenic delivery. Further research linking placental pathology, maternal disease and maternal PlGF levels is urgently needed before this test can be implemented in routine clinical practice. Copyright © 2018.

Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory breast disease that presents with variable local manifestations. We describe here the different management protocols based on the clinical presentation of these patients. A retrospective review of 20 histopathologic confirmed cases of IGM seen over a period of 10 years was performed. The median age was 34 years (age range: 21-45 years). All were married, parous with history of breast feeding. Ill-defined mass mimicking carcinoma was the commonest presentation (70%); however, with the presence of signs of inflammation like pain (55%), redness (40%), and peau d'orange (40%), an inflammatory process appeared more likely. Axillary lymph node enlargement was infrequently seen (40%). Radiologic findings (mammography and ultrasound) were nonspecific. Histopathology showed the characteristic lobular distribution of granulomatous inflammation in all cases. Surgically, 7 patients had abscess drainage with open biopsy, and 7 patients had lumpectomy. Six patients with diffuse breast involvement were diagnosed by core needle biopsy only. Microbial cultures showed no growth. Antibiotics were given empirically when signs of inflammation where present. Two patients needed further abscess drainage followed by persistent sinus excision 3-6 weeks later. The median follow-up was 24 months (range: 15-42 months). Seventeen patients (85%) were recurrence-free, and 3 patients (15%) were lost to follow-up. Management of IGM cases needs to be tailored according to the clinical presentation. Precise radiologic and pathologic data interpretation by a multidisciplinary breast team will facilitate diagnosis and minimize unnecessary intervention.

The purpose of this study was to investigate the factors influencing nurses' clinical decision making focusing on critical thinking disposition. The subjects of this study consisted of 505 nurses working at one of the general hospitals located in Seoul. Data was collected by a self-administered questionnaire between December 2006 and January 2007. Data was analyzed by one way ANOVA, Pearson correlation coefficients, and stepwise multiple regression using SPSS Win 14.0. The mean scores of critical thinking disposition and clinical decision making were 99.10 and 134.32 respectively. Clinical decision making scores were significantly higher in groups under continuing education, with a master or higher degree, with clinical experience more than 5 years, or with experts. Critical thinking disposition and its subscales have a significant correlation with clinical decision making. Intellectual eagerness/curiosity, prudence, clinical experience, intellectual honesty, self-confidence, and healthy skepticism were important factors influencing clinical decision making(adjusted R(2)=33%). Results of this study suggest that various strategies such as retaining experienced nurses, encouraging them to continue with education and enhancing critical thinking disposition are warranted for development of clinical decision making.

Bile duct loss during the course of drug induced liver injury is uncommon but can be an indication of vanishing bile duct syndrome. In this work we assess the frequency, causes, clinical features and outcomes of cases of drug induced liver injury with histologically proven bile duct loss. All cases of drug induced liver injury enrolled into a prospective database over a ten year period that had undergone liver biopsies (n=363) were scored for the presence of bile duct loss and assessed for clinical and laboratory features, causes and outcomes. 26 of the 363 patients (7%) with drug, herbal or dietary supplement associated liver injury had bile duct loss on liver biopsy which was moderate to severe (<50% of portal areas with bile ducts) in 14 and mild (50–75%) in 12. The presenting clinical features of the 26 cases varied, but the most common clinical pattern was a severe cholestatic hepatitis. The implicated agents included amoxicillin/clavulanate (n=3), temozolomide (n=3), various herbal products (n=3), azithromycin (n=2) and 15 other medications or dietary supplements. Compared to those without, those with bile duct loss were more likely to develop chronic liver injury (94% vs 47%), which was usually cholestatic and sometimes severe. Five patients died and two others underwent liver transplantation for progressive cholestasis despite treatment with corticosteroids and ursodiol. The most predictive factor of poor outcome was the degree of bile duct loss on liver biopsy. Conclusions Bile duct loss during acute cholestatic hepatitis is an ominous early indicator of possible vanishing bile duct syndrome, for which at present there are no known means of prevention or therapy.

Background: Although policies and guidelines make use of the concept of vulnerability, few define it. The European Union's directive for clinical trials does not include explanations for or the reasoning behind the designation of certain groups as vulnerable. Emerging economies from lower middle-income countries have, in recent years, had the largest average annual growth rate, as well as increase, in number of clinical trials registered in the US government's database. Nevertheless, careful supervision of research activities has to be ensured. Objective: To describe and analyze the features of the clinical trials involving vulnerable populations in various countries classified by development status and geographic region. Methods: Retrospective study that involved analysis of data obtained from the International Clinical Trials Registry Platform (ICTRP) database between 01/2014 and 12/2014 from countries with (i) highest trial densities during 2005 to 2012, (ii) highest average growth rate in clinical trials, and (iii) greatest trial capabilities. Results: Statistical analysis of this study showed that patients incapable of giving consent personally are 11.4 times more likely to be vulnerable patients than patients who are capable, and that patients in upper-middle-income countries are 1.7 times more likely to be vulnerable patients than patients from high-income countries when participating in global clinical trials. Malaysia (21%), Egypt (20%), Turkey (19%), Israel (18%), and Brazil (17%) had the highest percentages of vulnerable populations involving children. Conclusions: Although the inability to provide consent personally was a factor associated with vulnerability, arbitrary criteria may have been considered when classifying the populations of clinical trials as vulnerable. The EU Clinical Trials Register should provide guidance regarding exactly what aspects or factors should be taken into account to frame given populations as vulnerable, because

The current investigation aimed at studying the sociodemographic, clinical, and neuropsychological variables related to functional outcome in a sample of euthymic patients with bipolar disorder(BD) presenting moderate-severe levels of functional impairment. Two-hundred and thirty-nine participants with BD disorders and with Functioning Assessment Short Test(FAST) scores equal or above 18 were administered a clinical and diagnostic interview, and the administration of mood measure scales and a comprehensive neuropsychological battery. Analyses involved preliminary Pearson bivariate correlations to identify sociodemographic and clinical variables associated with the FAST total score. Regarding neuropsychological variables, a principal component analysis (PCA) was performed to group the variables in orthogonal factors. Finally, a hierarchical multiple regression was run. The best fitting model for the variables associated with functioning was a linear combination of gender, age, estimated IQ, Hamilton Depression Rating Scale (HAM-D), number of previous manic episodes, Factor 1 and Factor 2 extracted from the PCA. The model, including all these previous variables, explained up to 29.4% of the observed variance. Male gender, older age, lower premorbid IQ, subdepressive symptoms, higher number of manic episodes, and lower performance in verbal memory, working memory, verbal fluency, and processing speed were associated with lower functioning in patients with BD. © 2018 John Wiley & Sons A/S.

Traditional perspectives conceptualize resilience as a trait and depression as resulting from resilience deficiency. However, research indicates that resilience varies substantially even among adults who are clinically depressed, as well as across the lifespan of an individual. Few studies have investigated resilience in depression, and even fewer have examined resilience in depressed older adults. Three hundred thirty-seven adults ≥60 years with major depressive disorder completed the Connor-Davidson Resilience Scale (CD-RISC) and measures of mental health, quality of life (QOL), and medical comorbidity. Exploratory factor analysis was used to explore the factor structure of the CD-RISC. Correlations and general linear models were used to examine associations between resilience and other variables. The rotated component matrix indicated a four-factor model. Sorting of items by highest factor loading revealed constructs associated with (1) grit, (2) active coping self-efficacy, (3) accommodative coping self-efficacy, and (4) spirituality. Resilience was significantly correlated with increased age, lower cognitive functioning, greater cerebrovascular risk, and greater medical comorbidity. Resilience was negatively associated with mental health symptoms (depression, apathy, and anxiety) and positively associated with QOL. The final optimal model identified less depression, less apathy, greater medical comorbidity, higher QOL, and minority (non-White) race as factors that significantly explained variability in resilience. Resilience was significantly associated with a range of mental health constructs in a sample of older adults with depression. Future clinical trials and dismantling studies may help determine whether interventions targeting grit, active coping, accommodative coping, and spirituality can increase resilience and help prevent and treat depression in older adults.

To examine variables that affect publication of ACVO meeting abstracts in peer-reviewed journals and compare results to ECVO publication rate (PR). Published papers were identified via online searches for abstracts from 2008 to 2012 ACVO/ECVO meetings. Variables analyzed (via Pearson's chi-Squared test) included the following: oral presentation/poster, type of abstract (clinical/basic science/case report), species, ocular tissue, nationality, funding, first/last/any author a diplomate, resident as first author, and author affiliation (private practice/university). One hundred and eighty-six of 577 ACVO abstracts were published within 608 ± 479 days, with 103 published in Veterinary Ophthalmology. Significant factors included the following: nationality of first/last authors (P = .005); English as first language (P < .001); presentation type (P < .001, oral 40% PR, poster 22% PR); type of study (P = .037, clinical study 35% PR, basic science 30% PR, case report 16% PR); resident as first author (P < .001); diplomate as any author except first/last (P < .001); first author affiliation (P = .001, university 37% PR, practice 21% PR); last author affiliation (P = .003, university 36% PR, practice 22% PR); and species (P < .001, horses 53% PR, multiple species 50% PR, cats 35% PR, food animals 31% PR, exotics/wildlife 31% PR, dogs 27% PR, laboratory animals/in vitro 24%). Nonsignificant factors were as follows: diplomate as first/last author, funding, and ocular tissue. Presentation type, resident as first author, university affiliation of first author, and species had the greatest effect on publication probability. For the same period, ECVO PR was 87 of 299, which was not significantly different from ACVO PR (P = .342). At 32%, ACVO PR for the study years is similar to ECVO PR of 29%. © 2018 American College of Veterinary Ophthalmologists.

Abstract Purpose: There is evolving evidence that children and adolescents with gender dysphoria have higher-than-expected rates of autism spectrum disorder (ASD), yet clinical data on ASD among youth with gender dysphoria remain limited, particularly in North America. This report aims to fill this gap. Methods: We conducted a retrospective review of patient chart data from 39 consecutive youth ages 8 to 20 years (mean age 15.8 years, natal male: n = 22, natal female: n = 17) presenting for evaluation at a multidisciplinary gender clinic in a large U.S. pediatric hospital from 2007 to 2011 to evaluate the prevalence of ASD in this patient population. Results: Overall, 23.1% of patients (9/39) presenting with gender dysphoria had possible, likely, or very likely Asperger syndrome as measured by the Asperger Syndrome Diagnostic Scale (ASDS). Conclusion: These findings are consistent with growing evidence supporting increased prevalence of ASD in gender dysphoric children. To guide provision of optimal clinical care and therapeutic intervention, routine assessment of ASD is recommended in youth presenting for gender dysphoria. PMID:26651183

Carpal tunnel syndrome (CTS) is the most common neuropathy of the upper limb and a significant contributor to hand functional impairment and disability. Effective treatment options include conservative and surgical interventions, however it is not possible at present to predict the outcome of treatment. The primary aim of this study is to identify which baseline clinical factors predict a good outcome from conservative treatment (by injection) or surgery in patients diagnosed with carpal tunnel syndrome. Secondary aims are to describe the clinical course and progression of CTS, and to describe and predict the UK cost of CTS to the individual, National Health Service (NHS) and society over a two year period. In this prospective observational cohort study patients presenting with clinical signs and symptoms typical of CTS and in whom the diagnosis is confirmed by nerve conduction studies are invited to participate. Data on putative predictive factors are collected at baseline and follow-up through patient questionnaires and include standardised measures of symptom severity, hand function, psychological and physical health, comorbidity and quality of life. Resource use and cost over the 2 year period such as prescribed medications, NHS and private healthcare contacts are also collected through patient self-report at 6, 12, 18 and 24 months. The primary outcome used to classify treatment success or failures will be a 5-point global assessment of change. Secondary outcomes include changes in clinical symptoms, functioning, psychological health, quality of life and resource use. A multivariable model of factors which predict outcome and cost will be developed. This prospective cohort study will provide important data on the clinical course and UK costs of CTS over a two-year period and begin to identify predictive factors for treatment success from conservative and surgical interventions.

Suicidality is a continuum ranging from ideation to attempted and completed suicide, with a complex etiology involving both genetic heritability and environmental factors. The majority of suicide events occur in the context of psychiatric conditions, preeminently major depression and bipolar disorder. The present study investigates clinical factors associated with suicide in a sample of 553 mood disorder patients, recruited within the 'Psy Pluriel' center, Centre Européen de Psychologie Médicale, and the Department of Psychiatry of Erasme Hospital (Brussels). Furthermore, genetic association analyses examining polymorphisms within COMT, BDNF, MAPK1 and CREB1 genes were performed in a subsample of 259 bipolar patients. The presence or absence of a previous suicide attempt and of current suicide risk were assessed. A positive association with suicide attempt was reported for younger patients, females, lower educated, smokers, those with higher scores on depressive symptoms and higher functional disability and those with anxiety comorbidity and familial history of suicidality in first- and second-degree relatives. Anxiety disorder comorbidity was the stronger predictor of current suicide risk. No associations were found with polymorphisms within COMT and BDNF genes, whereas significant associations were found with variations in rs13515 (MAPK1) and rs6740584 (CREB1) polymorphisms. From a clinical perspective, our study proposes several clinical characteristics, such as increased depressive symptomatology, anxiety comorbidity, functional disability and family history of suicidality, as correlates associated with suicide. Genetic risk variants in MAPK1 and CREB1 genes might be involved in a dysregulation of inflammatory and neuroplasticity pathways and are worthy of future investigation.

To explore demographic and clinical factors associated with radiographic severity of first metatarsophalangeal joint osteoarthritis (OA) (First MTPJ OA). Adults aged ≥50 years registered with four general practices were mailed a Health Survey. Responders reporting foot pain within the last 12 months were invited to undergo a clinical assessment and weight-bearing dorso-plantar and lateral radiographs of both feet. Radiographic first MTPJ OA in the most severely affected foot was graded into four categories using a validated atlas. Differences in selected demographic and clinical factors were explored across the four radiographic severity subgroups using analysis of variance (ANOVA) and ordinal regression. Clinical and radiographic data were available from 517 participants, categorised as having no (n = 105), mild (n = 228), moderate (n = 122) or severe (n = 62) first MTPJ OA. Increased radiographic severity was associated with older age and lower educational attainment. After adjusting for age, increased radiographic first MTPJ OA severity was significantly associated with an increased prevalence of dorsal hallux and first MTPJ pain, hallux valgus, first interphalangeal joint (IPJ) hyperextension, keratotic lesions on the dorsal aspect of the hallux and first MTPJ, decreased first MTPJ dorsiflexion, ankle/subtalar joint eversion and ankle joint dorsiflexion range of motion, and a trend towards a more pronated foot posture. This cross-sectional study has identified several dose-response associations between radiographic severity of first MTPJ OA and a range of demographic and clinical factors. These findings highlight the progressive nature of first MTPJ OA and provide insights into the spectrum of presentation of the condition in clinical practice. Crown Copyright © 2014.

Urinary tract infection is common in children and result in permanent renal damage and end stage renal failure in significant number of patients. It is imperative to diagnose urinary tract infection early and to treat adequately. We carried out this study to look into frequency and clinical profile of UTI in children admitted in our unit. Three hundred and seventy five patients with UTI, diagnosed by urine culture with age from 0-15 years admitted in pediatric unit during 2003-2006 were included in study. Urine sample for culture was collected by midstream clean catch, urine collecting bag and Suprapubic methods depending upon the age of patient. A proforma was used to record clinical presentation and laboratory findings of these patients. Frequency of Urinary tract infections among children examined by urine culture was 375 out of 1000 (37.5%) out of which 36 (9.6%) were male and 339 (90.4%) were females. Almost half of them 48.5% were less than 3 years old. About 60% of patients belong to Kohistan and Batagram districts and failure to thrive was common presenting feature (56.6%) in patients of these two districts. Fever was common clinical presentation 91% followed by Dysuria (65%) and failure to thrive (40%). Frequency and clinical profile of urinary tract infection in children in Hazara Division is not significantly different from that of developing and developed countries.

Moyamoya is a rare cerebrovascular disease characterized by the progressive occlusion of the intracranial carotid artery. Thyroid autoantibodies have been found to be associated with the disease, but their clinical significance has never been studied. The objective of this study was to investigate the relationship between thyroid autoantibodies and the clinical presentation of moyamoya. This is a prospective study including 37 patients with moyamoya disease (MMD) or unilateral moyamoya (uMM). Thyroid function and thyroid autoantibodies (e.g., antithyroperoxidase and antithyroglobulin) were investigated. We studied the effect of gender, age, type of moyamoya (uMM versus MMD), and thyroid autoantibodies on the clinical presentation, dichotomized into aggressive (hemorrhage, major stroke, or frequent transient ischemic attack [TIA]) and nonaggressive presentation (headache, rare TIAs, and incidental diagnosis) according to the criteria of the Research Committee on Spontaneous Occlusion of the Circle of Willis. Of the 37 patients included in the study, the autoantibodies were elevated in 9 (24.3%). An aggressive presentation occurred in 21 patients (hemorrhage in 11, major stroke in 9, frequent TIAs in 1). The autoantibodies were elevated in 8 of the 21 patients (38.09%) with an aggressive presentation and in 1 of those presenting with minor symptoms (6.2%). The presence of elevated autoantibodies was the only variable associated with an aggressive presentation in the multivariate logistic analysis (P = .048). When the serum concentration of the thyroid autoantibodies is increased, the patients have a higher risk of an aggressive presentation. Our results support the hypothesis that activation of immune-mediated processes affects the moyamoya physiopathology. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

Transition of nursing student to new graduate depends on successful completion of clinical work placement during an undergraduate course. Supporting students during the clinical placement is imperative. This study examined associations between grade point average, domestic or international status, course entry qualification, and single or dual nursing degree to successful completion of clinical placement. A retrospective audit of 665 students in a baccalaureate nursing program was conducted to examine factors influencing clinical performance of baccalaureate nursing students. A significant association between entry qualification, lower grade point average, international status, and receipt of a constructive note was found: χ 2 = 8.678, df = 3, p = .034, t(3.862), df = 663, p ⩽ .001, and Fisher's exact test = 8.581, df = 1, p = .003, respectively. Understanding factors that affect clinical performance may help early identification of students at risk and allow for supportive intervention during placement and subsequent program completion.

The aim of this study was to describe the incidence and clinical characteristics, including intracoronary imaging features, of clinical restenosis in bioresorbable coronary scaffolds (BRS). Further, the authors searched for clinical and procedural predictors of scaffold restenosis (ScR) and report on the clinical outcomes after treatment of ScR in a cohort of consecutive all-comer patients. Data from randomized controlled trials demonstrate a higher rate of target lesion failure in patients treated with BRS as compared with those treated with metal drug-eluting stents. Although in-scaffold thrombosis has been thoroughly investigated, there are little data available on the incidence and characteristics of ScR. A total of 657 consecutive patients (age 63 ± 12 years, 79% men, 21% diabetics, 67% acute coronary syndrome) who received a total of 883 BRS for the treatment of coronary artery stenoses between May 2012 and January 2015 were enrolled in a retrospective registry. During the median follow-up of 1,076 days (interquartile range: 762 to 1,206 days), a total of 49 cases of ScR were found in 41 patients (Kaplan-Meier incidence: 2.4%, 6.0%, and 9.0% at 12-, 24-, and 36-month follow-up, respectively). ScR presented as stable angina or as incidental finding in 73% of the cases. The angiographic pattern was complex (type II to IV) in 55% of the ScR lesions. The neointima was homogeneous with high signal intensity in all but 3 cases at optical coherence tomography. Prior revascularization (hazard ratio [HR]: 2.7; 95% confidence interval [CI]: 1.5 to 5.1; p = 0.002), diabetes (HR: 2.9; 95%CI: 1.5 to 5.4; p = 0.001), lesion types B2 or C (HR: 2.8; 95% CI: 1.5 to 5.4; p = 0.002), and implantation technique (HR: 0.3; 95% CI: 0.1 to 0.6; p = 0.001) emerged as independent predictors of ScR. Oversizing (HR: 6.29; 95% CI: 2.4 to 16.4), undersizing (HR: 5.15; 95% CI: 1.99 to 13.30), and a residual stenosis >27% (HR: 8.9; 95% CI: 3.6 to 21.8) were associated with an

We investigated whether adverse responses to highly active antiretroviral therapy (HAART) associated with late HIV presentation are secondary to low CD4 cell count per se or other confounding factors. A longitudinal analysis of the UK Collaborative HIV Cohort (CHIC) Study of individuals starting HAART in 1998-2007 was carried out, comparing late presenters (presenting/starting HAART at a CD4 count <200 cells/μL) with late starters (presenting at a CD4 count>350 cells/μL; starting HAART at a CD4 count<200 cells/μL), using 'ideal starters' (presenting at a CD4 count>350 cells/μL; starting HAART at a CD4 count of 200-350 cells/μL) as a comparator. Virological, immunological and clinical (new AIDS event/death) outcomes at 48 and 96 weeks were analysed, with the analysis being limited to those remaining on HAART for>3 months. A total of 4978 of 9095 individuals starting first-line HAART with HIV RNA>500 HIV-1 RNA copies/mL were included in the analysis: 2741 late presenters, 947 late starters and 1290 ideal starters. Late presenters were more commonly female, heterosexual and Black African. Most started nonnucleoside reverse transcriptase inhibitors (NNRTIs); 48-week virological suppression was similar in late presenters and starters (and marginally lower than in ideal starters); by week 96 differences were reduced and nonsignificant. The median CD4 cell count increase in late presenters was significantly lower than that in late starters (weeks 48 and 96). During year 1, new clinical events were more frequent for late presenters [odds ratio (OR) 2.04; 95% confidence interval (CI) 1.19-3.51; P=0.01]; by year 2, event rates were similar in all groups. Amongst patients who initiate, and remain on, HAART, late presentation is associated with lower rates of virological suppression, blunted CD4 cell count increases and more clinical events compared with late starters in year 1, but similar clinical and immunological outcomes by year 2 to those of both late and ideal

The aims of this study were to assess the clinical characteristics of myasthenic crisis after thymectomy (MCAT) and to identify predictors affecting the occurrence of MCAT. Of 66 patients with myasthenia gravis (MG), MCAT occurred in 20 patients (30.3%). The median time interval from thymectomy to MCAT was 3.4 months. MCAT occurred in 65.0% of patients within the first 6 months of a thymectomy, and 35.0% after 6 months. A second MCAT occurred in nine (45.0%) patients who survived the first MCAT, and in seven (50.0%) of 14 patients with a history of a preoperative myasthenic crisis before thymectomy (MCBT). A history of MCBT, and clinical factors reflecting perioperative clinical severity at thymectomy, including preoperative Osserman's grade, bulbar symptoms, use of immunosuppressants, pulmonary function, and postoperative delayed ventilator weaning, were significantly correlated with the occurrence of MCAT on univariate analysis. However, a history of MCBT was the only independent factor affecting the occurrence of MCAT on multivariate logistic regression analysis (odds ratio, 17.9; 95% confidence interval, 4.019-79.873; p<0.001). Thus, the occurrence of MCAT may be correlated only with a history of MCBT rather than with factors reflecting perioperative clinical severity. MG patients with a history of MCBT are more susceptible to MCAT, particularly within the first 6 months of thymectomy. Copyright © 2011 Elsevier Ltd. All rights reserved.

These 5 cases of atypical inflammatory lymphogranula venereum (LGV) serovar L2b presenting initially with edema and persistent painful ulceration illustrate that clinical manifestations of LGV in the current outbreak in men who have sex with men reflect the influence of both the serovars virulence and the host immune system and are not confined to proctitis. L2b serovar could have a particular high virulence profile, and the need for awareness of LGV as a cause of genital ulceration is crucial.

Growth/differentiation factor-5: pre-clinical and clinical evaluations of periodontal regeneration and alveolar augmentation--review.

Growth/differentiation factor-5 (GDF-5) plays critical roles in mesenchymal cell differentiation and stimulates human periodontal ligament cell proliferation. Potentially, GDF-5 may also play roles in wound healing including periodontal regeneration and alveolar augmentation. The objective of this review was to provide up-to-date information from pre-clinical/clinical studies evaluating GDF-5 for these indications. A comprehensive search using PubMed and Google search engines was conducted to identify reports on GDF-5 applied to periodontal and alveolar indications. Two reviewers independently screened the titles and abstracts from a total of 479 reports. Full-length articles of 17 pre-clinical and four clinical studies were selected and reviewed. Canine-, porcine- and non-human primate-based models as well as human clinical trials were used in the evaluation of GDF-5 in support of periodontal regeneration and alveolar augmentation. An absorbable collagen sponge (ACS), β-tricalcium phosphate (β-TCP) and a poly(lactic-co-glycolic) acid (PLGA) were evaluated as candidate carriers for GDF-5 using various dose and healing intervals demonstrating significantly enhanced periodontal regeneration/alveolar augmentation including cementum, periodontal ligament and alveolar bone with limited, if any, adverse effects. Growth/differentiation factor-5 supports periodontal regeneration/alveolar augmentation without aberrant healing events documented in qualified pre-clinical models and clinical pilot studies. In perspective, GDF-5 appears a promising technology for periodontal regeneration/alveolar augmentation. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Coeliac disease is frequently associated with other immunomediated diseases. Our aim was to identify immunological comorbidities and possible risk factors for their development in coeliac patients. We recruited a cohort of 1,015 coeliac patients followed from 0 to 46 years in a single tertiary referral centre. Data were collected from the yearly scheduled clinical and serological evaluations. Possible risk factors such as demographic parameters, type of symptomatic presentation, gluten exposure, gluten-free diet compliance and family history were all evaluated. Subjects (848,606) from the regional health registry were investigated as controls. The prevalence of immunomediated diseases was higher in patients with coeliac disease compared to the registry population (23 % vs 0.4 %, p < 0.001). Diagnosis during paediatric age represented a risk factor for the presence of at least an immunomediated disease (hazard ratio = 1.62, 95 % confidence interval 1.15-2.29, p = 0.0061). Type of presentation and dietetic compliance did not represent risk factors. Long-standing gluten exposure reduced the risk of developing immunomediated diseases in coeliac subjects (hazard ratio for 1 year longer exposure 0.23, 95 % confidence interval 0.16-0.33, p < 0.0001). A familiar background characterized by the presence of immunological disorders was not a risk factor, although 419 (13 %) first degree relatives of coeliac patients out of 3,195 had an immunomediated disease. Our study suggests the need to investigate coeliac patients for other associated immunomediated diseases, independently of sex, gluten exposure and compliance to therapy; also subjects diagnosed in paediatric age should be carefully screened during follow up.

Delusional infestation is the conviction that one's skin is infested with foreign organisms or materials despite contradictory objective evidence. To delineate clinical characteristics of patients presenting with delusional infestation. We performed a retrospective study of patients meeting delusional infestation criteria who were seen for diagnosis and treatment in our tertiary care academic medical center (2001-2007). Medical records were reviewed to abstract demographic, historical, and physical findings and treatment. Over 7 years, 147 patients presented with delusional infestation; 87% (123/142) for another opinion. Mean age was 57 years; female-to-male ratio was 2.89 to 1; 82 (56%) were married. Mean duration of symptoms was 31 months. Employment data were available for 145 patients: 48 (33%) were self-described as disabled, 16 of whom cited delusions as their disability; 41 (28%) were retired; and 38 (26%) were employed. Reported infestations included multiple materials (45% [64/143]), not limited to insects (79% [113/143]), worms (27% [39/143]), and fibers (20% [29/143]). Most patients presented initially to dermatology or other specialties; only 3 presented to psychiatry. A high proportion (81%) had prior psychiatric conditions. Thirty-eight (26%) of the 147 patients had a shared psychotic disorder. The retrospective nature of the study and the incompleteness of some data because not all the characteristics that were analyzed were documented for every patient. Patients were predominantly female, had a long history of symptoms, and had been seen previously at many medical centers. A large proportion were disabled or retired. Patients reported skin infestation with both animate and inanimate objects. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

Besides viral serotype, HLA haplotype and cytokine genes polymorphism are associated with clinical presentation of hemorrhagic fever with renal syndrome. Since these analyses are unavailable in routine clinical practice, the aim of this study was to assess clinical, laboratory and radiographic findings associated with clinical presentation of disease severity. A total of 30 patients (27 men and 3 women), average age 40 +/- 14.9 years, treated for hemorrhagic fever with renal syndrome from January 1, 1999 to December 31, 2009 in Clinical Center of Serbia, were included in the study. Nine patients (30%) had mild, 14 (46.7%) moderate and 7 (23.3%) severe form of the disease; 24 (800%) recovered, 6 (20%) died in the acute phase of the illness, and 19 patients (63.3%) required hemodialysis. The average titer of antiviral antibodies in patients infected with Belgrade serotype virus were significantly higher in those with severe clinical presentation. Hypotension, anuria, macrohaematuria, pulmonary infiltration, pleural effusion, hepatomegalia and positive meningeal signs were more frequent in the patients with severe form of the disease. Statistically significant differences between groups with mild, moderate and severe clinical picture were found in serum total protein, albumin, calcium, glutamate pyruvate and glutamate oxaloacetate transaminase on admittance; serum creatinine and phosphorus concentration on day 14 and day 21; serum sodium and calciums on day 14; hemoglobine concentration on day 21. A statistically significant correlation was found between clinical presentation of the disease severity and platelet count, white blood cell count, hemoglobine concentration, serum calcium and serum transaminases on admittance. Multivariate analysis identified variables' combinations associated with clinical presentation of the disease. Our study confirmed that we can distinguish patients who will manifest different severities of the disease on the basis of careful

The purpose of the present study was to assess the impact of clinical presentation and pretest likelihood on the relation between coronary calcium score (CCS) and computed tomographic coronary angiography (CTA) to determine the role of CCS as a gatekeeper to CTA in patients presenting with chest pain. In 576 patients with suspected coronary artery disease (CAD), CCS and CTA were performed. CCS was categorized as 0, 1 to 400, and >400. On CT angiogram the presence of significant CAD (≥50% luminal narrowing) was determined. Significant CAD was observed in 14 of 242 patients (5.8%) with CCS 0, in 94 of 260 patients (36.2%) with CCS 1 to 400, and in 60 of 74 patients (81.1%) with CCS >400. In patients with CCS 0, prevalence of significant CAD increased from 3.9% to 4.1% and 14.3% in nonanginal, atypical, and typical chest pain, respectively, and from 3.4% to 3.9% and 27.3% with a low, intermediate, and high pretest likelihood, respectively. In patients with CCS 1 to 400, prevalence of significant CAD increased from 27.4% to 34.7% and 51.7% in nonanginal, atypical, and typical chest pain, respectively, and from 15.4% to 35.6% and 50% in low, intermediate, and high pretest likelihood, respectively. In patients with CCS >400, prevalence of significant CAD on CT angiogram remained high (>72%) regardless of clinical presentation and pretest likelihood. In conclusion, the relation between CCS and CTA is influenced by clinical presentation and pretest likelihood. These factors should be taken into account when using CCS as a gatekeeper for CTA.

Although law is established on a strong presumption that persons younger than a certain age are not competent to consent, statutory age limits for asking children's consent to clinical research differ widely internationally. From a clinical perspective, competence is assumed to involve many factors including the developmental stage, the influence of parents and peers, and life experience. We examined potential determining factors for children's competence to consent to clinical research and to what extent they explain the variation in competence judgments. From January 1, 2012 through January 1, 2014, pediatric patients aged 6 to 18 years, eligible for clinical research studies were enrolled prospectively at various in- and outpatient pediatric departments. Children's competence to consent was assessed by MacArthur Competence Assessment Tool for Clinical Research. Potential determining child variables included age, gender, intelligence, disease experience, ethnicity and socio-economic status (SES). We used logistic regression analysis and change in explained variance in competence judgments to quantify the contribution of a child variable to the total explained variance. Contextual factors included risk and complexity of the decision to participate, parental competence judgment and the child's or parents decision to participate. Out of 209 eligible patients, 161 were included (mean age, 10.6 years, 47.2 % male). Age, SES, intelligence, ethnicity, complexity, parental competence judgment and trial participation were univariately associated with competence (P < 0.05). Total explained variance in competence judgments was 71.5 %. Only age and intelligence significantly and independently explained the variance in competence judgments, explaining 56.6 % and 12.7 % of the total variance respectively. SES, male gender, disease experience and ethnicity each explained less than 1 % of the variance in competence judgments. Contextual factors together explained an extra 2

The recognition of clinical symptoms is critical to a therapeutic strategy for aortic valve stenosis (AS). It was hypothesized that AS symptoms might have multiple causes; hence, a study was conducted to investigate the factors that separately influence the classic symptoms of dyspnea, angina and syncope in AS. The medical records of 170 consecutive patients with AS (> or = moderate grade) were reviewed. A multivariate logistic regression analysis was used to evaluate the hemodynamic and clinical factors that separately influence the development of three clinical symptoms: dyspnea (defined as NYHA class > or = 2), angina, and syncope. The most common symptom was dyspnea (47.1%), followed by angina (12.4%) and syncope (4.7%). The factors associated with dyspnea were a higher e' ratio (p = 0.04) and peak aortic valve velocity (p = 0.01). Only the severity of AS was associated with syncope. The presence of hypertension was associated with angina (p = 0.04). Moreover, coronary angiography was performed in 59 patients before aortic valve replacement and revealed coronary stenosis (> 50% diameter stenosis) in 11/16 patients (69%) that had angina. The presence of coronary stenosis was significantly associated with angina (p = 0.02). The development of dyspnea, angina or syncope was influenced by different factors in AS. Dyspnea and syncope were mainly associated with AS severity, and diastolic dysfunction also influenced dyspnea. In contrast, angina was mainly related to the presence of coronary stenosis rather than to AS severity. These factors should be considered when, selecting a therapeutic strategy for AS patients in the modern era.

Purpose Eating disorders (EDs) impact both males and females, but little is known about sex differences in ED psychopathology and overall clinical presentation. This study compared demographic and clinical characteristics of child and adolescent males and females who presented for ED treatment. Methods Participants included 619 youth (59 males and 560 females) ages 6 to 18 years who presented for treatment between 1999 and 2011. Results Males presented for ED treatment at a significantly younger age (p < .001), earlier age of onset (p = .004), and were more likely to be non-White (p = .023). Females showed more severe eating disorder pathology across the Eating Disorder Examination subscales (weight concern: p < .001, eating concern: p < .001, restraint: p = .001, and shape concern: p = .019) and global score (p < .001). Males were more likely to present with an ED other than anorexia nervosa or bulimia nervosa (p = .002). Females presented with significantly higher rates of mood disorders (p = .027) and had a lower average percent of expected body weight (p = .020). Males and females did not differ in duration of illness, prior hospitalization or treatment, binging and purging episodes, anxiety disorders, behavioral disorders, or self-esteem. All analyses were controlled for age. Conclusion Results indicate that further exploration into why the sexes present differently may be warranted. Developing ED psychopathology assessments that better capture nuances particular to males and reevaluating criteria to better categorize male ED diagnoses may allow for more targeted treatment.

Primary extranodal lymphoma is known to occur in nose, gastrointestinal tract, skin, bone, and central nervous system. However, it is extremely rare for primary lymphoma to arise in skeletal muscle. We report a case of a 32-year-old man who presented initially with fever and fatigue. He had a history of alcohol abuse. Laboratory studies and computerized tomography scan showed results consistent with rhabdomyolysis, but the cause of the rhabdomyolysis was undetermined. After biopsy of abdominal skeletal muscle with histologic examination and T-cell receptor gamma chain gene rearrangement analysis, the diagnosis of peripheral T-cell lymphoma was established. After two cycles of the cyclophosphamide, doxorubicin, vincristine, prednisone, and etoposide regimen, the patient's symptoms greatly improved. This is the third reported case of peripheral T-cell lymphoma arising in skeletal muscle reported in the literature and which presented clinically with rhabdomyolysis. The alcohol abuse during the clinical course likely worsens the pathologic process of the rhabdomyolysis. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

Serious concerns have arisen in recent years regarding the unethical and illegal practices resorted to during clinical trials. Clinical trials in psychiatry are further complicated by issues such as 'validity of consent' and 'decision making capacity' of patients. This study was planned to explore the factors determining patient participation in clinical trials. A random sample of 123 consenting psychiatry inpatients were provided the information and consent-form of a hypothetical clinical drug trial. They were interviewed regarding their decision, the decision maker and factors that led to the decision. Family members tended to be the decision makers when patients were females, had low-income, were from rural background or had severe illnesses. Anticipated side effects and not wanting to interfere with existing treatment were the common reasons for refusal to participate while hope of betterment of the patient and benefit to humanity were cited for consent. The educated, urban, affluent class had more awareness regarding unethical trials and tended to be mistrustful of the medical community leading to higher rates of non-participation. Those who were adherent with ongoing treatment were also unwilling to participate. The lesser educated, low-income patients and rural domicile patients on the other hand had lesser awareness regarding clinical trials, trusted doctors and were more likely to participate. A good doctor-patient relationship, detailed explanations and clarification regarding the study and its conduct, and building awareness regarding clinical trials among vulnerable groups is necessary to ensure a valid consent involving no coercion, removal of prejudices, and ethical conduct of trials.

Bile duct loss during the course of drug-induced liver injury is uncommon, but can be an indication of vanishing bile duct syndrome (VBDS). In this work, we assess the frequency, causes, clinical features, and outcomes of cases of drug-induced liver injury with histologically proven bile duct loss. All cases of drug-induced liver injury enrolled into a prospective database over a 10-year period that had undergone liver biopsies (n = 363) were scored for the presence of bile duct loss and assessed for clinical and laboratory features, causes, and outcomes. Twenty-six of the 363 patients (7%) with drug-, herbal-, or dietary-supplement-associated liver injury had bile duct loss on liver biopsy, which was moderate to severe (<50% of portal areas with bile ducts) in 14 and mild (50%-75%) in 12. The presenting clinical features of the 26 cases varied, but the most common clinical pattern was a severe cholestatic hepatitis. The implicated agents included amoxicillin/clavulanate (n = 3), temozolomide (n = 3), various herbal products (n = 3), azithromycin (n = 2), and 15 other medications or dietary supplements. Compared to those without, those with bile duct loss were more likely to develop chronic liver injury (94% vs. 47%), which was usually cholestatic and sometimes severe. Five patients died and 2 others underwent liver transplantation for progressive cholestasis despite treatment with corticosteroids and ursodiol. The most predictive factor of poor outcome was the degree of bile duct loss on liver biopsy. Bile duct loss during acute cholestatic hepatitis is an ominous early indicator of possible VBDS, for which at present there are no known means of prevention or therapy.

Background The rising prevalence of diabetes mellitus (DM) worldwide, especially in developing countries, and the persistence of tuberculosis (TB) as a major public health issue in these same regions, emphasize the importance of investigating this association. Here, we compared the clinical profile and disease outcomes of TB patients with or without coincident DM in a TB reference center in Brazil. Methods We performed a retrospective analysis of a TB patient cohort (treatment naïve) of 408 individuals recruited at a TB primary care center in Brazil between 2004 and 2010. Data on diagnosis of TB and DM were used to define the groups. The study groups were compared with regard to TB disease presentation at diagnosis as well as to clinical outcomes such as cure and mortality rates upon anti-tuberculosis therapy (ATT) initiation. A composite score utilizing clinical, radiological and microbiological parameters was used to compare TB severity between the groups. Results DM patients were older than non-diabetic TB patients. In addition, diabetic individuals more frequently presented with cough, night sweats, hemoptysis and malaise than those without DM. The overall pattern of lung lesions assessed by chest radiographic examination was similar between the groups. Compared to non-diabetic patients, those with TB-diabetes exhibited positive acid-fast bacilli in sputum samples more frequently at diagnosis and at 30 days after ATT initiation. Notably, higher values of the TB severity score were significantly associated with TB-diabetes comorbidity after adjustment for confounding factors. Moreover, during ATT, diabetic patients required more frequent transfers to TB reference hospitals for complex clinical management. Nevertheless, overall mortality and cure rates were indistinguishable between the study groups. Conclusions These findings reinforce the idea that diabetes negatively impacts pulmonary TB severity. Our study argues for the systematic screening for DM in TB

Lead is an important toxic metal found in industrial communities. Due to the industrialization in the recent decade in Thailand, lead intoxication as a toxicant-related disorder becomes a new public health problem. A retrospective study on clinical presentation of hospitalized patients with diagnosis of lead intoxication during year 1990-1999 in King Chulalongkorn Memorial hospital, the largest Thai Red Cross Society Hospital, was performed. All 14 cases diagnosed with lead intoxication were identified in our series. Average age of the subjects was 25.55 +/- 21.93 years old. Male predominance was detected in our series (male:female = 12:2). Two main groups of subjects as; (1) childhood aged below 10 years old (male:female = 4:2) and (2) adult aged between 24 and 60 years old (n = 8, all male), can be identified. For the first group, the clinical presentations were convulsion (n = 3), unexplained anemia (n = 1), attention deficit (n = 1) and asymptomatic (n = 1), respectively. All of the subjects in this group presented the history of living at the old battery plant area. Five of the six cases came from the same village. For the second group, the clinical presentations were unexplained abdominal pain (n = 5), chronic renal failure (n = 1), unexplained anemia (n = 1) and asymptomatic (n = 1), respectively. Most of the subjects (75%) in this group presented the history of working in the battery plant for more than 10 years. Another case presented the history of gunshot and residual bullet in the bone marrow. The other one left is an interesting case with the history of prolonged usage of ritual pill and holy paper incineration. Like other studies, battery plant had strong relation with the lead intoxication. Although the total identified cases are rather few, there may be more undetected asymptomatic lead intoxication cases in the community. Specific control of lead resulted from battery plant and monitoring of the workers as public health strategies are still

Background/aims The Food and Drug Administration Amendments Act mandates that applicable clinical trials report basic summary results to the ClinicalTrials.gov database within 1 year of trial completion or termination. We aimed to determine the proportion of pulmonary trials reporting basic summary results to ClinicalTrials.gov and assess factors associated with reporting. Methods We identified pulmonary clinical trials subject to the Food and Drug Administration Amendments Act (called highly likely applicable clinical trials) that were completed or terminated between 2008 and 2012 and reported results by September 2013. We estimated the cumulative percentage of applicable clinical trials reporting results by pulmonary disease category. Multivariable Cox regression modeling identified characteristics independently associated with results reporting. Results Of 1450 pulmonary highly likely applicable clinical trials, 380 (26%) examined respiratory neoplasms, 238 (16%) asthma, 175 (12%) chronic obstructive pulmonary disease, and 657 (45%) other respiratory diseases. Most (75%) were pharmaceutical highly likely applicable clinical trials and 71% were industry-funded. Approximately 15% of highly likely applicable clinical trials reported results within 1 year of trial completion, while 55% reported results over the 5-year study period. Earlier phase highly likely applicable clinical trials were less likely to report results compared to phase 4 highly likely applicable clinical trials (phases 1/2 and 2 (adjusted hazard ratio 0.41 (95% confidence interval: 0.31-0.54)), phases 2/3 and 3 (adjusted hazard ratio 0.55 (95% confidence interval: 0.42-0.72)) and phase not applicable (adjusted hazard ratio 0.43 (95% confidence interval: 0.29-0.63)). Pulmonary highly likely applicable clinical trials without Food and Drug Administration oversight were less likely to report results compared with those with oversight (adjusted hazard ratio 0.65 (95% confidence interval: 0

Idiopathic CD4 lymphocytopenia (ICL) is a rare condition characterized by an unexplained deficit of circulating CD4 T cells leading to increased risk of serious opportunistic infections. The pathogenesis, etiology, clinical presentation, and best treatment options remain unclear. To describe the clinical presentation, treatment strategies, and outcome of patients with ICL seen in a single referral center. In a retrospective study, from January 1993 to January 2014, the demographic characteristics, clinical presentation, and treatments of patients diagnosed with ICL were reviewed. Twenty-four patients (14 female [58%] and 10 male [42%]) were evaluated. The mean age was 45 ± 17.6 years (range 7-76 years). Mean CD4 and CD8 T-cell counts at the time of diagnosis were 119 ± 84/mm 3 (range 4-294/mm 3 ) and 219 ± 258/mm 3 (range 7-630/mm 3 ), respectively. Seventeen patients (71%) had opportunistic infections, 4 (17%) had malignancies, and 3 (13%) had unexplained demyelinating disease and neurologic problems. Most patients had normal levels of immunoglobulins. Thirteen patients had abnormally low to absent response to phytohemagglutinin, concanavalin A, and antigens (candida and tetanus). Three patients had resolution of warts and 1 had mycobacterial lung infection on interleukin-2 with increases in CD4 count. The 11 patients on trimethoprim and sulfamethoxazole had no further hospital admissions for infections. The pathogenesis of ICL remains unclear. Although only some patients are healthy, most patients present with opportunistic infections. There is no known standard treatment aside from prophylactic antibiotics.

Chiari I malformation is a congenital, neurological condition that is characterized by defects of the skull base resulting in herniation of the cerebellum through the foramen magnum into the cervical spinal canal. Because the condition can result in visual symptoms, patients will often search for answers from their eye care providers; A 28-year-old Hispanic diabetic male with a 10-year history of nystagmus was referred to the neuro-ophthalmic disease clinic following the initiation of oscillopsia 1 year previous. Downbeat nystagmus, which worsened in right and down gaze, was evident. Cranial nerve testing was unremarkable, but the patient did report trouble with choking on food and drink. Neuroimaging revealed Chiari I malformation. The patient underwent a suboccipital craniectomy which resulted in lessened nystagmus and improved symptoms; The majority of patients with Chiari I malformation have an onset of symptoms in the second or third decade of life. Most commonly, a suboccipital headache that worsens with Valsalva maneuver is present. Visual symptoms include retro-orbital pain, flashing lights or floaters, blurred vision, photophobia, diplopia, transient vision loss, and peripheral vision loss. Objective evidence is often lacking in these patients; however, horizontal or vertical nystagmus is present in up to 45% of those with Chiari I malformation. Surgery has proven to be an effective and safe method to treat symptomatic Chiari I malformation. American Optometric Association.

There is increasing recognition of the unique physical and psychosocial concerns of the growing population of cancer survivors. An emerging literature demonstrates that fear of cancer recurrence (FCR) is a problematic long-term and late effect for cancer survivors. In fact, FCR is a top concern, and this article provides a necessary synthesis of the extant research evidence and theory. Literature searches were conducted using databases including MEDLINE and PsychINFO using specified search terms including 'fear of recurrence' and 'worry about recurrence'. A comprehensive narrative review summarizes early empirical findings on FCR including current definitions, assessment tools, clinical presentations, quality of life impact, prevalence, trajectory and risk factors. This paper also critically reviews the relevant theoretical frameworks to best understand these findings and considers multiple psychosocial treatment models that may have relevance for addressing FCR in the clinical setting. There is evidence of substantial prevalence and quality of life impact of FCR. Several theories (e.g. self-regulation model of illness, a family-based model, uncertainty in illness theory, social-cognitive processing theory, terror management theory) directly or indirectly help conceptualize FCR and inform potential treatment options for those with clinically significant distress or impairment resulting from FCR. Further investigation into FCR is warranted to promote evidence-based care for this significant cancer survivorship concern. Copyright © 2016 John Wiley & Sons, Ltd.

Hebert JJ, Koppenhaver SL, Magel JS, Fritz JM. The relationship of transversus abdominis and lumbar multifidus activation and prognostic factors for clinical success with a stabilization exercise program: a cross-sectional study. To examine the relationship between prognostic factors for clinical success with a stabilization exercise program and lumbar multifidus (LM) and transversus abdominis (TrA) muscle activation assessed using rehabilitative ultrasound imaging (RUSI). Cross-sectional study. Outpatient physical therapy clinic. Volunteers with current low back pain (N=40). Not applicable. We examined the relationship between prognostic factors associated with clinical success with a stabilization exercise program (positive prone instability test, age <40y, aberrant movements, straight leg raise >91 degrees , presence of lumbar hypermobility) and degree of TrA and LM muscle activation assessed by RUSI. Significant univariate relationships were identified between LM muscle activation and the number of prognostic factors present (Pearson correlation coefficient [r] =-.558, P=.001), as well as the individual factors of a positive prone instability test (point biserial correlation coefficient [r(pbis)]=.376, P=.018) and segmental hypermobility (r(pbis)=.358, P=.025). The multivariate analyses indicated that after controlling for other variables, the addition of the variable "number of prognostic factors present" resulted in a significant increase in R(2) (P=.006). No significant univariate or multivariate relationships were observed between the prognostic factors and TrA muscle activation. Decreased LM muscle activation, but not TrA muscle activation, is associated with the presence of factors predictive of clinical success with a stabilization exercise program. Our findings provide researchers and clinicians with evidence regarding the construct validity of the prognostic factors examined in this study, as well as the potential clinical importance of the LM muscle

Bridging the gap between clinical research and everyday health-care practice requires effective communication strategies. To address current shortcomings in conveying practice recommendations and supporting evidence, we are creating and testing presentation formats for clinical practice guidelines (CPGs). We carried out multiple cycles of brainstorming and sketching, developing a prototype. Physicians participating in the user testing viewed CPG formats linked to clinical scenarios and engaged in semistructured interviews applying a think-aloud method for exploring important aspects of user experience. We developed a multilayered presentation format that allows clinicians to successively view more in-depth information. Starting with the recommendations, clinicians can, on demand, access a rationale and a key information section containing statements on quality of the evidence, balance between desirable and undesirable consequences, values and preferences, and resource considerations. We collected feedback from 27 stakeholders and performed user testing with 47 practicing physicians from six countries. Advisory group feedback and user testing of the first version revealed problems with conceptual understanding of underlying CPG methodology, as well as difficulties with the complexity of the layout and content. Extensive revisions made before the second round of user testing resulted in most participants expressing overall satisfaction with the final presentation format. We have developed an electronic, multilayered, CPG format that enhances the usability of CPGs for frontline clinicians. We have implemented the format in electronic guideline tools that guideline organizations can now use when authoring and publishing their guidelines.

Background Nurses' practice takes place in a context of ongoing advances in research and technology. The dynamic and uncertain nature of health care environment requires nurses to be competent decision-makers in order to respond to clients' needs. Recently, the public and the government have criticized Iranian nurses because of poor quality of patient care. However nurses' views and experiences on factors that affect their clinical function and clinical decision-making have rarely been studied. Methods Grounded theory methodology was used to analyze the participants' lived experiences and their viewpoints regarding the factors affecting their clinical function and clinical decision-making. Semi-structured interviews and participant observation methods were used to gather the data. Thirty-eight participants were interviewed and twelve sessions of observation were carried out. Constant comparative analysis method was used to analyze the data. Results Five main themes emerged from the data. From the participants' points of view, "feeling competent", "being self-confident", "organizational structure", "nursing education", and "being supported" were considered as important factors in effective clinical decision-making. Conclusion As participants in this research implied, being competent and self-confident are the most important personal factors influencing nurses clinical decision-making. Also external factors such as organizational structure, access to supportive resources and nursing education have strengthening or inhibiting effects on the nurses' decisions. Individual nurses, professional associations, schools of nursing, nurse educators, organizations that employ nurses and government all have responsibility for developing and finding strategies that facilitate nurses' effective clinical decision-making. They are responsible for identifying barriers and enhancing factors within the organizational structure that facilitate nurses' clinical decision-making. PMID

Delusional Infestation (DI) is a relatively rare condition with a fixed belief of being infested with living organisms, despite a lack of medical evidence of such infestation. Although it seems to be a psychiatric disease, patients commonly are admitted to dermatology clinics because of skin findings. Psychiatrists can underestimate its prevalance, whereas dermatologists can miss the diagnosis. It should be managed as a psychodermatological disease. Our aim in the study was to evaluate six patients with different clinical presentations of DI and to emphasize some clinical features. All patients were internalized in the psychodermatology clinic for this study. Medical history and clinical data from dermatologic and psychiatric examinations were noted; Mini International Neuropsychiatric Interview (MINI-Plus) and laboratory investigations including blood and urine analyses, microscopic analysis of so-called pathogens, and skin biopsy if needed, were performed. The diagnosis was made based on detailed history, dermatologic and psychiatric examinations, and laboratory investigations. All patients had symptoms of itching, burning, or crawling sensations dermatologically and thus were admitted to dermatology clinic. They were all considered secondary DI to another medical condition or to psychiatric illness. Vitamin B12 deficiency, diabetes, and hypothyroidism were the underlying medical conditions. Related psychiatric illnesses were trichotillomania and schizoaffective disorder, schizophrenia, shared pychotic disorder, and brief psychotic disorder. Two patients had delusions of inanimate materials; four patients had partial and complete remissions; and two patients have dropped out. Each patient had different clinical characteristics creating diagnostic challenges. All complaints were related to the infestation of the skin. The presence of different psychiatric comorbidities is remarkable. It seems that both psychiatrists and dermatologists can face diagnostic and

The Arabic Scale of Death anxiety (ASDA), the Death Depression Scale (DDS), and the Death Obsession Scale (DOS) were administered, individually, to 7 groups (n = 765) of Egyptian normal participants (non-clinical), anxiety disorder patients, patients suffering from schizophrenia (males and females), and addicts (males only). They were generally matched as groups according to age, occupation, and education. The intercorrelations between the 3 scales in all 7 groups were significant and positive. A general high-loaded factor of death distress was extracted in all 7 groups. It was the only salient factor, accounting for 50-70% of the common variance.

Tuberculosis (TB) is a rare cause of otitis media. This study aims to increase awareness on the clinical presentation of TB otitis media and illustrate how early detection affects treatment outcome. Chart review of 12 patients (13 ears) from a tertiary hospital in Manila, Philippines, seen from 2004 to 2009. Clinical predictors of the disease were summarized. Clinical, radiologic, and audiometric outcomes after treatment were compared between treatment groups. The 5 otoscopic presentations were multiple perforations, single perforation with refractory otorrhea and exuberant granulation tissue formation, single perforation with minimal otorrhea and no granulation tissue formation, intact tympanic membrane with middle ear effusion, and intact tympanic membrane with tumorlike tissue in the middle ear. Clinical predictors of the disease were history of pulmonary TB, work-related contamination of the infection, positive purified protein derivative test, positive chest radiographic finding and intraoperative granulation tissue with cheesy material, and temporal bone computed tomographic scan findings. Patients who had no middle ear surgery showed significantly better clinical, radiologic, and audiometric outcomes than those who were diagnosed late and had more complicated surgical procedure. The clinical presentation of TB otitis media is variable. Early detection of the early forms entail less surgical intervention and favors better treatment results.

Introduction: The main aim of this study was to describe the clinical manifestation of tuberculosis infection cases in Malaysia and to determine the individual risk factors for their occurrence. Methodology: The study adopted a quantitative research approach with use of descriptive statistical approach. The study setting was a community clinic which treats walk in patients who are mainly living and working in the surrounding areas. The study was conducted for a period of one year. All tuberculosis patients who sought treatment in the clinic during the time were included in this study. The total number of cases was 40. Data was collected from the medical records of the tuberculosis patients. The risk factors selected for investigation were demographic characteristics of age and sex, personal habits such as smoking, drug use and alcohol and presence of diseases such as human immunodeficiency virus positive (HIV+), diabetes mellitus, cancer, cyanotic heart disease, renal failure and steroid use. Results: Patients in the age group ranging from 41 to 50 years had the highest incidence of the infection. Smoking appears to be the most important risk factor for contracting followed by drug abuse, HIV+ infection and diabetes mellitus. Conclusions: People with diseases such as diabetes mellitus and HIV that are high risk factors for TB should be screened for TB so that early detection and intervention is possible. Educational programs should be carried out to create awareness among the at risk groups. PMID:25946947

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurologic condition associated with systemic lupus erythematosus (SLE). This study aimed to demonstrate the risk factors and clinical outcome of PRES in patients with SLE. Fifteen patients with SLE were diagnosed with PRES by characteristic clinical manifestations and magnetic resonance imaging (MRI) features from 2000 to 2012. Clinical profiles and outcomes were assessed for this study population. Additionally, 48 SLE patients with neurologic symptoms who underwent brain MRI were included for comparative analyses. The median age and duration of SLE in patients with PRES was 27 and 6.1 years, respectively. Comparison between patients with and without PRES revealed significant differences in the presentation of hypertension and seizure, lupus nephritis with renal insufficiency, treatment with high-dose steroid and cyclophosphamide, recent transfusion, and lupus activity measured by SLE disease activity index. Renal failure was the single independent factor with a high odds ratio of 129.250 by multivariate analysis. Of 15 patients, four experienced relapse and two died of sepsis during hospitalization. Our results suggest that lupus nephritis with renal dysfunction and other related clinical conditions can precede the occurrence of PRES in patients with SLE. It is important to perform early brain imaging for a timely diagnosis of PRES when clinically suspected.

Present Status of Radiotherapy in Clinical Practice

Aims of radiation oncology are cure from malignant diseases and - at the same time preservation of anatomy (e.g. female breast, uterus, prostate) and organ functions (e.g. brain, eye, voice, sphincter ani). At present, methods and results of clinical radiotherapy (RT) are based on experiences with natural history and radiobiology of malignant tumors in properly defined situations as well as on technical developments since World War II in geometrical and biological treatment planning in teletherapy and brachytherapy. Radiobiological research revealed tolerance limits of healthy tissues to be respected, effective total treatment doses of high cure probability depending on histology and tumor volume, and - more recently - altered fractionation schemes to be adapted to specific growth fractions and intrinsic radiosensitivities of clonogenic tumor cells. In addition, Biological Response Modifiers (BRM), such as cis-platinum, oxygen and hyperthermia may steepen cell survival curves of hypoxic tumor cells, others - such as tetrachiordekaoxid (TCDO) - may enhance repair of normal tissues. Computer assisted techniques in geometrical RT-planning based on individual healthy and pathologic anatomy (CT, MRT) provide high precision RT for well defined brain lesions by using dedicated linear accelerators (Stereotaxy). CT-based individual tissue compensators help with homogenization of distorted dose distributions in magna field irradiation for malignant lymphomas and with total body irradiation (TBI) before allogeneic bone marrow transplantation, e.g. for leukemia. RT with fast neutrons, Boron Neutron Capture Therapy (BNCT), RT with protons and heavy ions need to be tested in randomized trials before implementation into clinical routine.

Delayed diagnosis of choroidal neovas cularization (CNV) in age-related macular degeneration (AMD) adversely affects visual outcome. To identify factors associated with early detection of CNV in the clinic setting. Demographic and clinical data and lesion characteristics were retrospectively collected from 76 consecutive AMD patients who had a history of CNV in one eye and presented with CNV in the second eye. These data were evaluated for association with visual acuity (VA) at the time of presentation. Better VA was associated with a history of CNV in the fellow eye (P < 0.0001), adherence to follow-up every 4 months (P = 0.015), younger age (P = 0.03), smaller lesion (P < 0.0001), and non-subfoveal location (P = 0.048). VA of the fellow eye did not correlate with VA at presentation with CNV. These data suggest that patients' experience of CNV, regardless of VA, facilitates early diagnosis in the fellow eye. Adherence to follow-up in the routine clinic setting also facilitates early detection of CNV.

Systemic mast cell activation disorders (MCADs) are characterized by severe and systemic mast cell (MC) mediators-related symptoms frequently associated with increased serum baseline tryptase (sBt). To analyze the clinical, biological, and molecular characteristics of adult patients presenting with systemic MC activation symptoms/anaphylaxis in the absence of skin mastocytosis who showed clonal (c) versus nonclonal (nc) MCs and to provide indication criteria for bone marrow (BM) studies. Eighty-three patients were studied. Patients showing clonal BM MCs were grouped into indolent systemic mastocytosis without skin lesions (ISMs(-); n = 48) and other c-MCADs (n = 3)-both with CD25(++) BM MCs and either positive mast/stem cell growth factor receptor gene (KIT) mutation or clonal human androgen receptor assay (HUMARA) tests-and nc-MCAD (CD25-negative BM MCs in the absence of KIT mutation; n = 32) and compared for their clinical, biological, and molecular characteristics. Most clonal patients (48/51; 94%) met the World Health Organization criteria for systemic mastocytosis and were classified as ISMs(-), whereas the other 3 c-MCAD and all nc-MCAD patients did not. In addition, although both patients with ISMs(-) and patients with nc-MCAD presented with idiopathic and allergen-induced anaphylaxis, the former showed a higher frequency of men, cardiovascular symptoms, and insect bite as a trigger, together with greater sBt. Based on a multivariate analysis, a highly efficient model to predict clonality before BM sampling was built that includes male sex (P = .01), presyncopal and/or syncopal episodes (P = .009) in the absence of urticaria and angioedema (P = .003), and sBt >25 microg/L (P = .006) as independent predictive factors. Patients with c-MCAD and ISMs(-) display unique clinical and laboratory features different from nc-MCAD patients. A significant percentage of c-MCAD patients can be considered as true ISMs(-) diagnosed at early phases of the disease. Copyright

Objective. To examine the clinical characteristics and financial charges associated with treating adult cancer patients receiving chemotherapy in outpatient clinics who presented to the emergency department (ED) with neutropenia. Design and Setting. A retrospective audit was conducted across two health services involving ED episodes and subsequent hospital admissions of patients who received chemotherapy through day oncology from January 1 to December 31, 2007 and presented to the ED with neutropenia. ED data were collected from the Victorian Emergency Minimum Dataset and charges were collected from Health Information Services. Descriptive and bivariate statistics were used to describe the patient and clinical characteristics and financial outcomes, and to explore associations between these factors. Results. In total, 200 neutropenic episodes in 159 outpatients were seen in the ED over the survey period. The mean patient age was 56.6 years (standard deviation, 13.2 years) and 47.2% were male. Overall, 70.0% of ED episodes were triaged as Australasian Triage Scale 2 (emergency). The median ED wait time was 10 minutes and the median ED length of stay was 6.8 hours. The median charge for each ED episode was $764.08 Australian dollars. The total combined ED and inpatient charge per episode was in the range of $144.27–$174,732.68, with a median charge of $5,640.87. Conclusions. This study provides important insights into the clinical and economic burden of neutropenia from both the ED and inpatient perspectives. Alternative treatment models, such as outpatient treatment, early discharge programs or prophylactic interventions to reduce the clinical and economic burden of neutropenia on our health system, must be explored.

Although the typical clinical manifestations of multiple myeloma (MM) are summarized by the CRAB symptoms (hypercalcemia, renal insufficiency, anemia, and bone lesions), a significant proportion of patients with MM present with a variety of other clinical manifestations. We conducted a study evaluating the presenting symptoms that led to the diagnosis of MM. We conducted a retrospective review of 170 consecutive patients with MM seen at the Penn State Hershey Cancer Institute. Among patients with symptomatic MM, 74% presented with CRAB symptoms, 20% presented with non-CRAB manifestations, and 6% had both clinical features. Ten categories of non-CRAB manifestations were found, in order of decreasing frequency: neuropathy (because of spinal cord compression, nerve root compression, or peripheral neuropathy), extramedullary involvement, hyperviscosity syndrome, concomitant amyloidosis (eg, nephrotic syndrome or cardiopathy), hemorrhage/coagulopathy, systemic symptoms (eg, fever or weight loss), primary plasma cell leukemia, infections, cryoglobulinemia, and secondary gout. Kaplan-Meier estimates of survival in patients with non-CRAB manifestations did not show a significant difference from the survival of patients presenting with CRAB symptoms. Presenting symptoms of MM may be grouped in a total of 14 categories, 4 for the CRAB and 10 for the less common non-CRAB features. Grouped together, non-CRAB manifestations do not appear to confer a negative effect on the prognosis of patients with MM.

The Clinical Learning Environment, Supervision and Nurse Teacher (CLES+T) scale measures student nurses' perceptions of clinical learning environments. This study evaluates the construct validity and internal reliability of the CLES+T in hospital settings in New Zealand. Comparisons are made between New Zealand and Finnish data. The CLES+T scale was completed by 416 Bachelor of Nursing students following hospital clinical placements between October 2008 and December 2009. Construct validity and internal reliability were assessed using exploratory factor analysis and Cronbach's alpha. Exploratory factor analysis supports 4 factors. Cronbach's alpha ranged from .82 to .93. All items except 1 loaded on the same factors found in unpublished Finnish data. The first factor combined 2 previous components from the published Finnish component analysis and was renamed: connecting with, and learning in, communities of clinical practice. The remaining 3 factors (Nurse teacher, Supervisory relationship, and Leadership style of the manager) corresponded to previous components and their conceptualizations. The CLES+T has good internal reliability and a consistent factor structure across samples. The consistency across international samples supports faculties and hospitals using the CLES+T to benchmark the quality of clinical learning environments provided to students.

Differences in cognition and brain structure have been found in youth with type 1 diabetes compared with controls, even after relatively short disease duration. To determine whether severity of clinical presentation contributes to these differences, we obtained structural magnetic resonance imaging (MRI) scans in youth ages 7-17 who were either newly diagnosed with type 1 diabetes (<3.5 months from diagnosis, n  = 46) or a sibling without diabetes (n = 28). Severity of presentation was measured by the presence of diabetic ketoacidosis (DKA) and degree of hyperglycemia exposure [hemoglobin A1c (HbA1c)] at diagnosis. MRI were obtained using T1-weighted, T2-weighted, and diffusion-weighted sequences. Within the group with type 1 diabetes, 12 subjects presented in DKA and 34 did not. After controlling for age, sex, and multiple comparisons, the type 1 diabetes group had lower volume in the left temporal-parietal-occipital cortex compared with controls. Within the type 1 diabetes group, DKA at presentation was associated with lower radial, axial, and mean diffusivity (MD) throughout major white matter tracts and higher HbA1c was associated with lower hippocampal, thalamic, and cerebellar white matter volumes, lower right posterior parietal cortical thickness, and greater right occipital cortical thickness. These data suggest that severity of clinical presentation is an important factor in predicting brain structural differences in youth with type 1 diabetes approximately 3 months after diagnosis. © 2016 John Wiley & Sons A/S.

In rheumatoid arthritis (RA), seropositive and seronegative disease may be two entities with different underlying pathophysiological mechanisms, long-term outcomes and disease presentations. However, the effect of the conjoint presence of multiple autoantibodies, as proxy for a more pronounced humoral autoimmune response, on clinical phenotype remains unclear. Therefore, this study investigates the association between the number of autoantibodies and initial clinical presentation in two independent cohorts of patients with early RA. Autoantibody status (rheumatoid factor, anticitrullinated protein antibodies and anticarbamylated protein antibodies) was determined at baseline in the Leiden Early Arthritis Cohort (n=828) and the Swedish BARFOT (Better Anti-Rheumatic Farmaco-Therapy, n=802) study. The association between the number of autoantibodies and baseline clinical characteristics was investigated using univariable and multivariable ordinal regression. In both cohorts, the following independent associations were found in multivariable analysis: patients with a higher number of RA-associated antibodies were younger, more often smokers, had a longer symptom duration and a higher erythrocyte sedimentation rate at presentation compared with patients with few autoantibodies. The number of autoantibodies, reflecting the breadth of the humoral autoimmune response, is associated with the clinical presentation of RA. Predisease pathophysiology is thus reflected by the initial clinical phenotype. Published by the BMJ Publishing Group Limited.

One of the most common complaints among postmenopausal women is a change in sexual drive. The aim of this study was to assess the current state of sexual health in Spanish postmenopausal women who present at outpatient gynecology clinics. In this multicenter, observational, cross-sectional, questionnaire-based study, a survey was conducted that included 3026 Spanish postmenopausal women in a routine clinical setting in outpatient gynecology clinics at public and private institutions throughout Spain. We used the Women's Sexual Function questionnaire, which has been validated in Spain. In the multivariate analysis, we found that the best indicators of sexual health in postmenopausal women were a higher education (p < 0.001), working or previously worked (p < 0.001), a stable partner (p < 0.001), living in an urban area (p < 0.01), healthy habits and received information about menopause (p < 0.001). These results indicate that it is important to provide health education and information about menopause and the complaints associated with this period in a woman's life.

Dental Erosion and Its Growing Importance in Clinical Practice: From Past to Present

2012-01-01

Since the mid-1990s, the focus of studies on tooth wear has steadily shifted from the general condition towards the more specific area of dental erosion; equally, a shift has occurred from studies in adults to those in children and adolescents. During this time, understanding of the condition has increased greatly. This paper attempts to provide a critical overview of the development of this body of knowledge, from earlier perceptions to the present. It is accepted that dental erosion has a multifactorial background, in which individual and lifestyle factors have great significance. Notwithstanding methodological differences across studies, data from many countries confirm that dental erosion is common in children and young people, and that, when present, it progresses rapidly. That the condition, and its ramifications, warrants serious consideration in clinical dentistry, is clear. It is important for the oral healthcare team to be able to recognize its early signs and symptoms and to understand its pathogenesis. Preventive strategies are essential ingredients in the management of patients with dental erosion. When necessary, treatment aimed at correcting or improving its effects might best be of a minimally invasive nature. Still, there remains a need for further research to forge better understanding of the subject. PMID:22505907

Eating disorders (EDs) have been underdiagnosed in many clinical settings. This study investigates the influence of clinical characteristics on presenting symptoms of patients with EDs. Psychiatric outpatients, aged 18-45, were enrolled sequentially and received a two-phase survey for EDs in August 2010-January 2013. Their primary reasons for seeking psychiatric help were obtained at their first encounter with outpatient psychiatrists. Patients' clinical and demographic characteristics were compared according to presenting symptoms with or without eating/weight problems. Of 2140 patients, 348 (16.3%) were diagnosed with an ED (22.6% of women and 6.3% of men). The three most common reasons for seeking psychiatric help were eating/weight problems (46.0%), emotional problems (41.3%), and sleep disturbances (19.3%). The multivariate analyses suggest that when patients with EDs presented symptoms that were less related to eating/weight problems, they were significantly more likely to be those having diagnoses other than anorexia nervosa or bulimia nervosa and less severe degree of binge-eating. Further, patients with EDs who demonstrated more impulsive behaviors and poorer functioning were less likely to report their eating problems when visiting psychiatric clinics. Thus, ED should be assessed routinely in patients with complex psychopathology to facilitate comprehensive treatment. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Psychiatric symptoms as a clinical presentation of Cushing’s syndrome

2013-01-01

Cushing’s syndrome can present with a spectrum of symptoms; however, it is less recognised that psychiatric symptoms can form part of the clinical presenting features. In the investigations for an organic cause for a psychiatric illness, Cushing’s syndrome needs to be considered, especially if there are other features such as hirsutism or hypertension. In this article, the two cases reported demonstrate that a prompt diagnosis is not only important for psychiatric management but also crucial for timely institution of the necessary treatment of life-threatening causes of hypercortisolaemia such as metastatic adrenal carcinoma.

Background Determinants of the clinical presentation of the leishmaniases are poorly understood but Leishmania species and strain differences are important. To examine the relationship between clinical presentation, species and isoenzyme polymorphisms, 56 Leishmania isolates from distinct presentations of American tegumentary leishmaniasis (ATL) from Ecuador were analyzed. Methods Isolates were characterized by multilocus enzyme electrophoresis for polymorphisms of 11 isoenzymes. Patients were infected in four different ecologic regions: highland and lowland jungle of the Pacific coast, Amazonian lowlands and Andean highlands. Results Six Leishmania species constituting 21 zymodemes were identified: L. (Viannia) panamensis (21 isolates, 7 zymodemes), L. (V.) guyanensis (7 isolates, 4 zymodemes), L. (V.) braziliensis (5 isolates, 3 zymodemes), L. (Leishmania) mexicana (11 isolates, 4 zymodemes), L. (L.) amazonensis (10 isolates, 2 zymodemes) and L. (L.) major (2 isolates, 1 zymodeme). L. panamensis was the species most frequently identified in the Pacific region and was associated with several clinical variants of cutaneous disease (CL); eight cases of leishmaniasis recidiva cutis (LRC) found in the Pacific highlands were associated with 3 zymodemes of this species. Mucocutaneous leishmaniasis found only in the Amazonian focus was associated with 3 zymodemes of L. braziliensis. The papular variant of CL, Uta, found in the Andean highlands was related predominantly with a single zymodeme of L. mexicana. Conclusion Our data show a high degree of phenotypic variation within species, and some evidence for associations between specific variants of ATL (i.e. Uta and LRC) and specific Leishmania zymodemes. This study further defines the geographic distribution of Leishmania species and clinical variants of ATL in Ecuador. PMID:16968553

Information related to mastitis risk factors is useful for the design and implementation of clinical mastitis (CM) control programs. The first objective of our study was to model the risk of CM under Brazilian conditions, using cow-specific risk factors. Our second objective was to explore which risk factors were associated with the occurrence of the most common pathogens involved in Brazilian CM infections. The analyses were based on 65 months of data from 9,789 dairy cows and 12,464 CM cases. Cow-specific risk factors that could easily be measured in standard Brazilian dairy farms were used in the statistical analyses, which included logistic regression and multinomial logistic regression. The first month of lactation, high somatic cell count, rainy season and history of clinical mastitis cases were factors associated with CM for both primiparous and multiparous cows. In addition, parity and breed were also associated risk factors for multiparous cows. Of all CM cases, 54% showed positive bacteriological culturing results from which 57% were classified as environmental pathogens, with a large percentage of coliforms (35%). Coagulase-negative Staphylococcus (16%), Streptococcus uberis (9%), Streptococcus agalactiae (7%) and other Streptococci (9%) were also common pathogens. Among the pathogens analyzed, the association of cow-specific risk factors, such as Zebu breed (OR=5.84, 95%CI 3.77-10.77) and accumulated history of SCC (1.76, 95%CI 1.37-2.27), was different for CM caused by Coagulase-negative Staphylococcus and S. agalactiae in comparison to CM caused by coliforms. Our results suggest that CM control programs in Brazil should specially consider the recent history of clinical mastitis cases and the beginning of the lactations, mainly during the rainy season as important risk factor for mastitis.

A sample of 200 cases involving human-directed canine aggression and 200 control cases involving no instance of human-directed aggression were selected at random from a population of 746 cases. The final model suggested that clinical cases with human-directed aggression were significantly younger than those presenting with other undesired behaviours (P=0.008) and that male dogs were 1.4 times more likely to be aggressive towards human beings than female dogs (P=0.019). Dogs were 1.7 times more likely to be aggressive towards people if they had attended more than five puppy classes than if they had never attended puppy class (P=0.015) and that dogs were 2.8 times more likely to be aggressive towards human beings if there was another dog between 0 months and 24 months of age in the home (P=0.004). These factors only account for 7 per cent to 10 per cent of the variance between the human-directed aggression population and the control population, but factors such as attendance at puppy classes and numbers of dogs in the household suggest the need for longitudinal studies to investigate temporal relationships.

Uncomplicated UTI is among the most common health problems seen in general practice and typically affects immunocompetent, anatomically normal women. The aim of this study was to explore the difference in clinical presentation in acute, uncomplicated UTI in otherwise healthy community dwelling, premenopausal (Pre-M) and postmenopausal (Post-M) women. A UTI was defined as uropathogen of more than 10(3)cfu/ml in midstream urine culture. Symptoms of UTI were divided to three: during voiding, local symptoms, and generalized symptoms. A total of 196 women aged a minimum of 45 years with diagnosis of UTI were studied. The patients were divided into two groups: Pre-M (n=102, mean age 48.14 years) and Post-M (n=94, mean age 69.21 years). The predominant complaints in Pre-M women were local symptoms. The clinical presentations showed more severity in the Post-M group than in Pre-M women, predominantly generalized unspecific symptoms and storage symptoms. Advanced age positively correlated with urgency of urination, painful voiding, urinary incontinence, sexual activity, low-back pain, lower abdominal pain and negatively correlated with frequency, painful and burning of urination and bladder pain. Our study showed that clinical presentation of UTI in Pre-M and Post-M women is different. The differences are presented not only by the voiding itself and by local symptoms but also by unspecified generalized symptoms that is especially important in elderly patients. Copyright © 2011.

Exogenous factors in panic disorder: clinical and research implications.

PubMed

Roy-Byrne, P P; Uhde, T W

1988-02-01

Because panic disorder has an underlying biologic and probably genetic basis, the role of factors outside the organism in initiating and sustaining panic is often overlooked. The authors review certain exogenous factors that seem capable of triggering attacks and/or increasing their frequency and intensity: self-administered pharmacologic agents (caffeine, alcohol, nicotine, over-the-counter cold preparations, cannabis, cocaine); habits (sleep deprivation, diet, exercise, relaxation, hyperventilation); and aspects of the environment (fluorescent lighting, life stressors). There may be a specificity to the action of some of these factors, because certain factors previously thought to trigger panic attacks (e.g., pain, hypoglycemia) have been proved not to have this effect. Although the clinical significance of many of the exogenous factors discussed still awaits empirical confirmation, attention to such factors during the initial evaluation of a patient with panic disorder may be helpful in formulating a successful treatment plan.

Providing or withholding of treatment is based on a variety of factors. We sought for criteria in clinical decision making and reviewed attitudes towards clinical intuition and the patient's will. 503 physicians (25.6 % females; mean age 36.3) in 49 departments at nine hospitals of the universities Bochum and Magdeburg filled in a validated questionnaire. The most important factors in the decision to carry out a therapy were "international standards" and "own experience". The decision to omit a therapy was mainly influenced by the "patient's wish". Physicians with a higher status judged their own experience higher than young physicians, who considered the experience of colleagues more important. "Severe accompanying illnesses" and "multimorbidity" were the most frequently named reasons to withdraw a therapy. Intuitive decision-making was rare, especially in young physicians, although these decisions were seldom risky and often successful. A patient's will plays a prominent role in clinical decision making, especially in decisions to withdraw or to withhold treatment. Cost containment and research interest have been called less important, a remarkable response from research-based university hospitals. Also remarkable is the recognition and importance of clinical intuition in situations of complex or missing information. This important aspect is rarely discussed in the literature or in medical education. The widely voiced concern that priorities in clinical care are guided by scientific interest, financial or technical possibilities could not be confirmed.

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.

Introduction: Cerebral palsy (CP) is the most common physical disorder of children. Causes like jaundice and birth injury though are decreasing; complications resulting from the survival of low birth weight babies are replacing some of the older etiologies. Hence, this study was planned. Objectives: The objective was to study the clinical patterns, predisposing factors, and co-morbidities in children with CP. Materials and Methods: The present study is a hospital based prospective study conducted from January 2012 to January 2013 in children presenting to neurodevelopmental clinic at a tertiary care teaching hospital in India. Hundred cases with clinical features suggestive of CP were included in the study. Cases were evaluated by history, clinical examination, and necessary investigations. Results: Results of the study showed 81% of spastic, 12% of hypotonic, 5% of dystonic, and 2% of mixed CP cases. The mean age of presentation was 2 year, 2 month, and male to female ratio of 1:2. Pregnancy-induced hypertension (PIH) was the most common antenatal complication observed in 6%. Four percent had neonatal sepsis and 19% were born premature. Associated co-morbidities were mental retardation (55%), seizure disorder (46%), visual problems (26%), hearing problems (19%), and failure to thrive (47%). Discussion: Sex distribution observed in our study was male to female ratio of 1.2, which was comparable with a multicenter study in Europe. PIH was observed in 6% of cases, which was comparable with prior studies. Birth asphyxia was observed in 43% of cases. Eighty-one percent of the cases constituted a spastic variety of CP which was comparable to other studies. Conclusion: Perinatal asphyxia was the important etiological factor. We found preventable intranatal causes (60%) and antenatal causes (20%) forming a significant proportion. Co-morbidities were significantly observed in our study. PMID:26167210

Detecting Breech Presentation Before Labour: Lessons From a Low-Risk Maternity Clinic.

PubMed

Ressl, Bill; O'Beirne, Maeve

2015-08-01

Evaluation of fetal position is an important part of prenatal care. A woman with a breech presentation may need referral for external cephalic version, for assisted breech delivery, or to schedule a Caesarean section. In many centres, a breech presentation undetected until labour will result in an emergency Caesarean section, a less desirable alternative for both the mother and the health care system. The anecdotal reports of undiagnosed breech presentations at a busy maternity clinic prompted a study to quantify the missed breech presentations and to evaluate the effectiveness of the current detection process, with the aim of allowing no more than 1% of breech presentations to remain undetected until labour. We performed a retrospective analysis of 102 breech deliveries over a 14 month period to quantify missed breech presentations, and used a prospective physician survey documenting how fetal presentation was determined at 186 prenatal visits over four months to analyze the current detection process. We found that approximately 8% of breech presentations were undetected until labour. We concluded that within the limitations of the small sample size evaluated, the current practice of using a vaginal examination to verify fetal presentation determined by abdominal palpation (Leopold's manoeuvres) may not be more accurate than abdominal palpation alone. The current detection process resulted in an unacceptably high rate of missed breech presentations. The results of this study prompted the clinic's acquisition of bedside ultrasound capability to assess fetal position.

A 45-year-old Asian man presented with acute-onset periorbital and facial edema associated with pyrexia. Muscle weakness was absent. Initial laboratory investigations showed an inflammatory reaction, while screening for infections was negative. Serum muscle enzyme levels were normal. He was hospitalized and treated empirically with antibiotics and corticosteroids, pending the result of facial skin and muscle biopsy. He showed a good clinical and laboratory response but an attempt to discontinue corticosteroids led to a prompt relapse of facial edema and pyrexia, associated with rising laboratory indices of inflammation. Biopsy findings were typical of dermatomyositis. Reintroduction of corticosteroid treatment resulted in complete clinical and laboratory remission. Facial edema as the sole clinical manifestation of dermatomyositis is extremely rare. There have been no previous reports of isolated facial edema in the setting of acute, clinically amyopathic dermatomyositis in adults. A high level of suspicion is required to make the diagnosis in the absence of myopathy and the hallmark cutaneous manifestations of the disease (heliotrope rash, Gottron papules). PMID:29707197

Suicidal behavior (SB) is a major, worldwide health concern. To date there is limited understanding of the associated motivational aspects which accompany this self-initiated conduct. To develop a method for identifying motivational features associated with SB by studying admitted psychiatric patients, and to examine their clinical relevance. By performing a factor analytic study using data obtained from a patient sample exhibiting high suicidality and a variety of SB methods, Motivations for SB Scale (MSBS) was constructed to measure the features. Data included assessments of DSM-IV psychiatric and personality disorders, suicide intent, depressive symptomatology, overt aggression, recent life events (RLEs) and methods of SB, collated from structured interviews. Association of identified features with clinical variables was examined by correlation analyses and MANCOVA. Factor analyses elicited a 4-factor solution composed of Interpersonal-testing (IT), Interpersonal-change (IC), Self-renunciation (SR) and Self-sustenance (SS). These factors were classified according to two distinctions, namely interpersonal vs. intra-personal directedness, and the level of assumed influence by SB or the relationship to prevailing emotions. Analyses revealed meaningful links between patient features and clinical variables. Interpersonal-motivations (IT and IC) were associated with overt aggression, low suicidality and RLE discord or conflict, while SR was associated with depression, high suicidality and RLE separation or death. Borderline personality disorder showed association with IC and SS. When self-strangulation was set as a reference SB method, self-cutting and overdose-taking were linked to IT and SS, respectively. The factors extracted in this study largely corresponded to factors from previous studies, implying that they may be useful in a wider clinical context. The association of these features with SB-related factors suggests that they constitute an integral part of the

Childhood maltreatment is associated with a wide range of problems in adulthood. However, specific environmental factors (either positive or negative) influence mental health outcomes in maltreated children. The present study investigated the effect of environmental factors by comparing a group of clinical participants with experiences of abuse/neglect with a healthy group with similar patterns of experiences. Environmental factors selected were: separation from parents, financial hardship, parental psychiatric disorders, and low social involvement. The study included 55 mixed clinical participants and 23 healthy participants. All participants were investigated using the Childhood Experience of Care and Abuse (CECA) interview. The two groups were specifically matched with regard to patterns of childhood maltreatment. The findings indicated that psychopathological outcome was associated with a greater presence of negative environmental factors (p < 0.001). In particular, lack of social support seemed to be the only one predictor (OR = 27.86). This study is the first to investigate the influence of specific environmental factors in two groups with similar childhood experiences of abuse/neglect but different mental health outcomes. These findings suggest that efforts should be made to incorporate both familial and external sources of social support in promoting mental health for maltreated children. © 2015 S. Karger AG, Basel.

In vivo recovery of factor VIII and factor IX: intra- and interindividual variance in a clinical setting.

PubMed

Björkman, S; Folkesson, A; Berntorp, E

2007-01-01

In vivo recovery (IVR) is traditionally used as a parameter to characterize the pharmacokinetic properties of coagulation factors. It has also been suggested that dosing of factor VIII (FVIII) and factor IX (FIX) can be adjusted according to the need of the individual patient, based on an individually determined IVR value. This approach, however, requires that the individual IVR value is more reliably representative for the patient than the mean value in the population, i.e. that there is less variance within than between the individuals. The aim of this investigation was to compare intra- and interindividual variance in IVR (as U dL1 per U kg1) for FVIII and plasma-derived FIX in a cohort of non-bleeding patients with haemophilia. The data were collected retrospectively from six clinical studies, yielding 297 IVR determinations in 50 patients with haemophilia A and 93 determinations in 13 patients with haemophilia B. For FVIII, the mean variance within patients exceeded the between-patient variance. Thus, an individually determined IVR value is apparently no more informative than an average, or population, value for the dosing of FVIII. There was no apparent relationship between IVR and age of the patient (1.5-67 years). For FIX, the mean variance within patients was lower than the between-patient variance, and there was a significant positive relationship between IVR and age (13-69 years). From these data, it seems probable that using an individual IVR confers little advantage in comparison to using an age-specific population mean value. Dose tailoring of coagulation factor treatment has been applied successfully after determination of the entire single-dose curve of FVIII:C or FIX:C in the patient and calculation of the relevant pharmacokinetic parameters. However, the findings presented here do not support the assumption that dosing of FVIII or FIX can be individualized on the basis of a clinically determined IVR value.

Previous studies have been unable to identify risk factors for prevalent vertebral fractures (VF), which are suitable for use in selection strategies intended to target high-risk sub-groups for diagnostic assessment. However, these studies generally consisted of large epidemiology surveys based on questionnaires and were only able to evaluate a limited number of risk factors. Here, we investigated whether a stronger relationship exists with prevalent VF when conventional risk factors are combined with additional information obtained from detailed one-to-one assessment. Women aged 65-75 registered at four geographically distinct GP practices were invited to participate (n=1,518), of whom 540 attended for assessment as follows: a questionnaire asking about risk factors for osteoporosis such as height loss compared to age 25 and history of non-vertebral fracture (NVF), the get-up-and-go test, Margolis back pain score, measurement of wall-tragus and rib-pelvis distances, and BMD as measured by the distal forearm BMD. A lateral thoraco-lumbar spine X-ray was obtained, which was subsequently scored for the presence of significant vertebral deformities. Of the 509 subjects who underwent spinal radiographs, 37 (7.3%) were found to have one or more VF. Following logistic regression analysis, the four most predictive clinical risk factors for prevalent VF were: height loss (P=0.006), past NVF (P=0.004), history of back pain (P=0.075) and age (P=0.05). BMD was also significantly associated with prevalent VF (P=0.002), but its inclusion did not affect associations with other variables. Factors elicited from detailed one-to-one assessment were not related to the risk of one or more prevalent VFs. The area under ROC curves derived from these regressions, which suggested that models for prevalent VF had modest predictive accuracy, were as follows: 0.68 (BMD), 0.74 (four clinical risk factors above) and 0.78 (clinical risk factors + BMD). Analyses were repeated in relation to the

Increasing reports on the incidental ingestion of metallic bristles from barbeque grill cleaning brushes have been reported. We sought to describe the clinical presentation and grilling habits of patients presenting after ingesting metallic bristles in an attempt to identify risk factors. We performed a chart review of six patients with documented enteric injury from metallic bristles. Subjects were contacted and administered a survey focused on the events surrounding the bristle ingestion. We arranged for in-home visits to inspect the grill and grill brush whenever possible. Of the six subjects identified, three (50%) were male, five (83%) were white, and they ranged in age from 18 to 65 years (mean 42.5). All complained of abdominal pain. All bristles were identified by CT scan. Three patients underwent laparoscopic enterorrhaphy, and two underwent laparotomy. The remaining patients did not require intervention. None had replaced their grill brush in at least two years. Surgeon's awareness of this unusual injury is important to identify and manage this problem. Alternative methods to clean the grill should be sought and grill brushes should be replaced at least every two years.

Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, inflammatory neurodegenerative disease. This study investigated the relationships of clinical stage with epidemiological and magnetic resonance imaging (MRI) findings in SSPE by retrospective review of 76 cases (57 male) diagnosed by typical periodic electroencephalographic features, clinical symptoms and elevated measles antibody titre in cerebrospinal fluid. Clinical stage at diagnosis was I or II in 48 patients, III in 25 and IV in three. Prominent findings at presentation were atonic/myoclonic seizures (57.9%) and mental deterioration with behaviour alteration (30.3%). Frequent MRI findings (13 - 32 patients) were subcortical, periventricular and cortical involvement and brain atrophy; the corpus callosum, basal ganglia, cerebellum and brainstem were less frequently involved. Five patients had pseudotumour cerebri. Cranial MRI at initial diagnosis was normal in 21 patients (19 stage I/II, two stage III/IV). Abnormal MRI findings were significantly more frequent in the later stages, thus a normal initial cranial MRI does not exclude SSPE, which should, therefore, be kept in mind in childhood demyelinating diseases even when the presentation is unusual.

New policies in China have recently led to the implementation of clinical pharmacy services in hospitals. We explored the views of hospital administrators, pharmacy directors, clinical pharmacists, and dispensing pharmacists about the factors affecting clinical pharmacy services in China, using the framework approach and organizational theory. We conducted 30 interviews with 130 participants at 29 hospitals (both secondary and tertiary) in Beijing, Zhengzhou, Luoyang, and Shanghai. We found that the barriers to and facilitators of implementation of clinical pharmacy services slotted into the environment and participant dimensions of Scott's adapted version of Leavitt's organizational model. External support from government was perceived as crucial to promoting pharmacy services. It is proposed that the internationally recognized Basel Statements of the International Pharmaceutical Federation also provide a strong foundation for guiding China in implementing clinical pharmacy services.

The factor structure and psychometric properties of the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE-OM) in Norwegian clinical and non-clinical samples

PubMed Central

2013-01-01

Background The Clinical Outcomes in Routine Evaluation - Outcome Measure (CORE-OM) is a 34-item instrument developed to monitor clinically significant change in out-patients. The CORE-OM covers four domains: well-being, problems/symptoms, functioning and risk, and sums up in two total scores: the mean of All items, and the mean of All non-risk items. The aim of this study was to examine the psychometric properties of the Norwegian translation of the CORE-OM. Methods A clinical sample of 527 out-patients from North Norwegian specialist psychiatric services, and a non-clinical sample of 464 persons were obtained. The non-clinical sample was a convenience sample consisting of friends and family of health personnel, and of students of medicine and clinical psychology. Students also reported psychological stress. Exploratory factor analysis (EFA) was employed in half the clinical sample. Confirmatory (CFA) factor analyses modelling the theoretical sub-domains were performed in the remaining half of the clinical sample. Internal consistency, means, and gender and age differences were studied by comparing the clinical and non-clinical samples. Stability, effect of language (Norwegian versus English), and of psychological stress was studied in the sub-sample of students. Finally, cut-off scores were calculated, and distributions of scores were compared between clinical and non-clinical samples, and between students reporting stress or no stress. Results The results indicate that the CORE-OM both measures general (g) psychological distress and sub-domains, of which risk of harm separates most clearly from the g factor. Internal consistency, stability and cut-off scores compared well with the original English version. No, or only negligible, language effects were found. Gender differences were only found for the well-being domain in the non-clinical sample and for the risk domain in the clinical sample. Current patient status explained differences between clinical and non-clinical

Clinical Implications From an Exploratory Study of Postural Management of Breech Presentation

PubMed Central

Founds, Sandra A.

2013-01-01

The results from an exploratory study of the effectiveness of maternal knee-chest posture for producing cephalic version of breech presentation are shown. Methods are briefly described and clinical implications are presented. Among 25 women, fewer who performed the maternal knee-chest postural intervention experienced fetal cephalic version than women in the control group who did nothing to influence breech presentation. Despite limitations of the underpowered findings, trends in the data may indicate that parity and gestational age were potentially relevant covariates of version. Postural management is not an evidence-based practice. This exploratory study indicates that maternal knee-chest posture may work opposite to the expected direction, but the small sample size precludes generalizations about efficacy of knee-chest postural management. At least one adequately powered trial that controls for parity and gestational age is needed to determine whether knee-chest postural management results in no effect, a small, or small to moderate clinically significant effect.

The underpinnings of maltreatment in children presenting with burn injuries are necessary to discern as detection and prevention rest on a clear delineation of factors associated with maltreatment. Inaccurate identification of child victims can result in perpetuation of the maltreatment and its attendant neuropsychological sequela. The authors sought to determine factors associated with maltreatment in children presenting with burn injuries, which would guide the burn team in assessing the likelihood of maltreatment. All consenting children admitted with burn injuries were surveyed regarding their injury mechanism and current sociodemographic status. Suspicious injuries were referred by the burn team to the multidisciplinary review team (MRT). The MRT reported injuries with signs of physical abuse, supervision neglect, neglect of other basic needs, or sexual abuse. These children constituted the cases in our study. Variables related to maltreatment were entered into stepwise logistic regression to identify independent predicting variables. P< .05 was considered significant. MRT identified 16 children (24%) admitted with burn injuries with suspicions of maltreatment. Risk factors related to suspicions of maltreatment included: young age, large burns, tap water injury, immersion lines, delay in care, absence of a two-parent family (unconventional family structure), young parents, inconsistent history, and injury pattern. In this single-center prospective study, the authors identified several factors that, when present in injuries with initial suspicion of maltreatment, should trigger a child maltreatment workup. Burn clinicians have an important role as advocates for children and their families. It is important to continue to further the knowledge of maltreatment detection and prevention among children presenting with burn injuries.

To determine the clinical features and risk factors of presumed ocular toxoplasmosis (POT) in patients affected with the condition at Irrua, Nigeria. The study included 69 patients with POT, and 69 age and sex matched subjects who served as the control group. Data was obtained using interviewer administered questionnaires. Examination included measurement of visual acuity (VA), intraocular pressure (IOP), slit lamp examination, gonioscopy and dilated fundus examination. Mean age of cases and control subjects was 57.16 ± 18.69 and 56.09 ± 16.01 years respectively. The peak age group in patients with POT was 60 years and above. The most common presenting complaint was blurred vision occurring in 100% of cases. Drinking unfiltered water in 58 (84.1%) patients was the most common risk factor. Other risk factors included post cataract surgery status in 32 (46.4%) subjects, ingestion of poorly cooked meat in 30 (43.5%) cases and exposure to cats in 9 (13.0%) patients. All risk factors were more common in POT patients (P < 0.05). Out of 69 patients, 62 (89.9%) had unilateral while 7 (10.1%) had bilateral involvement. Out of 76 eyes with uveitis, 53 (69.7%) were blind. Active disease was significantly more common with increasing age (P < 0.05). Patients with POT were rather old and some risk factors were modifiable, therefore health education for preventing the transmission of toxoplasmosis and provision of sanitary water may help reduce the incidence of ocular toxoplasmosis.

Autoimmune encephalitis with anti-N-methyl-d-aspartate receptor autoantibodies (NMDA-R-Abs) is a recently described disease affecting adult and pediatric patients. Symptoms of the disease are now perfectly described in the adult population but the clinical presentation is less known in young children. The aim of the present study was to describe the clinical presentation and the specificities of symptoms presented by young children with NMDA-R-Abs encephalitis to improve diagnosis of this disease, and to compare these to a series of previously published female adult patients. Fifty cases of children younger than twelve years of age diagnosed with NMDA-R-Abs encephalitis between January 1, 2007 and December 31, 2016 (27 females and 23 males) were retrospectively studied. The first neurological symptoms observed in young children with NMDA-R-Abs encephalitis were characterized by seizure (72%), especially focal seizure (42%), within a median of 15 days before other encephalitis symptoms; other patients mostly had behavioral disorders (26%). The seizures were frequently difficult to diagnose because of the transient unilateral dystonic or tonic posturing presentation or sudden unilateral pain in the absence of clonic movements. A post-ictal motor deficit was also frequently observed. This clinical presentation is different from that observed in adult females with NMDA-R-Abs encephalitis who initially present mainly psychiatric disorders (67%) or cognitive impairment (19%), and less frequently seizures (14%). The diagnosis of NMDA-R-Abs encephalitis should be systematically considered in young children of both sexes who present neurological symptoms suggesting recent seizures (focal or generalized) without obvious other etiology.

Hyperthyroidism in adults: variable clinical presentations and approaches to diagnosis.

PubMed

Knudson, P B

Hyperthyroidism is a disease that has various symptoms and can present in many ways. In the elderly patient hyperthyroidism often is not expressed in the classical manner. A case report of a middle-aged man who had hyperthyroidism with only one symptom is detailed. A literature review utilizing MEDLINE files from 1988 to the present, as well as current textbooks of medicine and endocrinology, was used to prepare this report. Keywords for the search were "hyperthyroidism," "symptoms," "unintentional weight loss," and "differential diagnosis." The clinical presentation of hyperthyroidism can vary from almost asymptomatic to apathetic in appearance to a marked hyperdynamic physiologic response. Family physicians must be well informed of this variation in disease expression. Overlooking the diagnosis of this relatively easily treated condition can be detrimental to patient care and expensive.

Little data exist about the quality of care for HIV-infected subjects in Germany. We investigated the clinical course of HIV-infected subjects newly presenting in our HIV outpatient clinic. Antiretroviral therapy (ART)-naïve HIV-infected subjects presenting between 2007 and 2008 were followed until June 2012. Clinical data and laboratory parameters were collected prospectively and analysed retrospectively. From 281 subjects included, 34 patients (12%) were lost to follow-up. 247 subjects remained, and 171 patients were followed for 1,497 days [1,121/1,726] (all data: median [interquartile range]). ART was started in 199 patients (81%) 182 days [44/849] after HIV diagnosis, and all patients were treated according to European guidelines or within clinical trials. The CD4 cell count at first presentation was 320/µL [160/500] and declined to 210/µL [100/300] at ART start. 12 months thereafter, the CD4 cell count increased to 410/µL [230/545]. The HIV RNA was suppressed below 50 copies/mL after 108 days [63/173] in 182 patients (91%). Initial ART was changed in 71 patients (36%) after 281 days [99/718], in five patients (7%) due to virological failure, in 66 patients (93%) due to other reasons, e.g. side effects or patient's request. Two-thirds of the included patients were followed for more than 3 years, and ART was initiated in 81% of the patients leading to complete virological suppression in most patients. Compliance of physicians with treatment guidelines was high. Late presentation with a severely compromised immune function remains a problem and impairs the otherwise good prognosis of HIV infection.

Unrecognized and inadequately repaired intraoperative durotomies may lead to cerebrospinal fluid leak, pseudomeningocele, and other complications. Few studies have investigated durotomy that is unrecognized intraoperatively and requires additional postoperative management (hereafter, late-presenting dural tear [LPDT]), although estimates of LPDT range from 0.6 to 8.3 per 1,000 spinal surgeries. These single-center studies are based on relatively small sample sizes for an event of this rarity, all with <10 patients experiencing LPDT. This investigation is the largest yet conducted on LPDT, and sought to identify incidence, risk factors for, and complications associated with LPDT. This observational cohort study employed the American College of Surgeons National Surgical Quality Improvement Program dataset (years 2012-2015). Patients who underwent spine surgery were identified based on presence of primary listed Current Procedural Terminology (CPT) codes corresponding to spinal fusion or isolated posterior decompression without fusion. The primary variable in this study was occurrence of LPDT, identified as reoperation or readmission with durotomy-specific CPT or International Classification of Diseases, Ninth Revision, Clinical Modification codes but without durotomy codes present for the index procedure. Descriptive statistics were generated. Bivariate and multivariate analyses were conducted using chi-square tests and multiple logistic regression, respectively, generating both risk factors for LPDT and independent association of LPDT with postoperative complications. Statistical significance was defined as p<.05. In total, 86,212 patients were analyzed. The overall rate of reoperation or readmission without reoperation for LPDT was 2.0 per 1,000 patients (n=174). Of LPDT patients, 97.7% required one or more unplanned reoperations (n=170), and 5.7% of patients (n=10) required two reoperations. On multivariate analysis, lumbar procedures (odds ratio [OR] 2.79, p

Polycythemia vera (PV) in children and adolescents is very rare. Data on clinical and laboratory evaluations as well as on treatment modalities are sparse. Here, we report the long-term clinical course of a PV patient first diagnosed more than 40 years ago at age 12. In addition, after a systematic review of the scientific medical literature, clinical and hematological data of 35 patients (19 female and 17 male) from 25 previous reports are summarized. Three patients developed PV following antecedent hematological malignancies. Budd-Chiari syndrome was diagnosed in seven patients indicating a particular risk of young patients of developing this disorder. One patient presented with ischemic stroke, one patient with gangrene, and three patients with severe hemorrhage. Three patients died from disease-related complications. Hematocrit levels and platelet counts were not correlated with disease severity. Leukocytosis >15 x 10(9)/L was present in 9/35 patients and associated with a thromboembolic or hemorrhagic complication in seven patients. The few available data on molecular genetics and endogenous erythroid colony growth indicate changes comparable to those detectable in adult patients. Treatment varied enormously. It included aspirin, phlebotomy, hydroxycarbamide, busulfan, melphalan, pyrimethamine, and interferon-alpha. Two patients successfully underwent stem cell transplantation. Currently, it is impossible to treat an individual pediatric PV patient with an evidence-based regimen.

Several classification schemes have been developed for anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), with actual debate focusing on their clinical and prognostic performance. Sixty-two patients with renal biopsy-proven AAV from a single center in Mexico City diagnosed between 2004 and 2013 were analyzed and classified under clinical (granulomatosis with polyangiitis [GPA], microscopic polyangiitis [MPA], renal limited vasculitis [RLV]), serological (proteinase 3 anti-neutrophil cytoplasmic antibodies [PR3-ANCA], myeloperoxidase anti-neutrophil cytoplasmic antibodies [MPO-ANCA], ANCA negative), and histopathological (focal, crescenteric, mixed-type, sclerosing) categories. Clinical presentation parameters were compared at baseline between classification groups, and the predictive value of different classification categories for disease and renal remission, relapse, renal, and patient survival was analyzed. Serological classification predicted relapse rate (PR3-ANCA hazard ratio for relapse 2.93, 1.20-7.17, p = 0.019). There were no differences in disease or renal remission, renal, or patient survival between clinical and serological categories. Histopathological classification predicted response to therapy, with a poorer renal remission rate for sclerosing group and those with less than 25 % normal glomeruli; in addition, it adequately delimited 24-month glomerular filtration rate (eGFR) evolution, but it did not predict renal nor patient survival. On multivariate models, renal replacement therapy (RRT) requirement (HR 8.07, CI 1.75-37.4, p = 0.008) and proteinuria (HR 1.49, CI 1.03-2.14, p = 0.034) at presentation predicted renal survival, while age (HR 1.10, CI 1.01-1.21, p = 0.041) and infective events during the induction phase (HR 4.72, 1.01-22.1, p = 0.049) negatively influenced patient survival. At present, ANCA-based serological classification may predict AAV relapses, but neither clinical nor serological

Deep dyspareunia negatively affects women's sexual function. There is a known association between deep dyspareunia and endometriosis of the cul-de-sac or uterosacral ligaments in reproductive-age women; however, other factors are less clear in this population. To identify anatomic sites and associated clinical factors for deep dyspareunia in reproductive-age women at a referral center. This study involved the analysis of cross-sectional baseline data from a prospective database of 548 women (87% consent rate) recruited from December 2013 through April 2015 at a tertiary referral center for endometriosis and/or pelvic pain. Exclusion criteria included menopausal status, age at least 50 years, previous hysterectomy or oophorectomy, and not sexually active. We performed a standardized endovaginal ultrasound-assisted pelvic examination to palpate anatomic structures for tenderness and reproduce deep dyspareunia. Multivariable regression was used to determine which tender anatomic structures were independently associated with deep dyspareunia severity and to identify clinical factors independently associated with each tender anatomic site. Severity of deep dyspareunia on a numeric pain rating scale of 0 to 10. Severity of deep dyspareunia (scale = 0-10) was independently associated with tenderness of the bladder (b = 0.88, P = .018), pelvic floor (levator ani) (b = 0.66, P = .038), cervix and uterus (b = 0.88, P = .008), and cul-de-sac or uterosacral ligaments (b = 1.39, P < .001), but not with the adnexa (b = -0.16, P = 0.87). The number of tender anatomic sites was significantly correlated with more severe deep dyspareunia (Spearman r = 0.34, P < .001). For associated clinical factors, greater depression symptom severity was specifically associated with tenderness of the bladder (b = 1.05, P = .008) and pelvic floor (b = 1.07, P < .001). A history of miscarriage was specifically associated with tenderness of the cervix and uterus (b = 2.24, P = .001

Background Clinical decision support systems can prevent knowledge-based prescription errors and improve patient outcomes. The clinical effectiveness of these systems, however, is substantially limited by poor user acceptance of presented warnings. To enhance alert acceptance it may be useful to quantify the impact of potential modulators of acceptance. Methods We built a logistic regression model to predict alert acceptance of drug–drug interaction (DDI) alerts in three different settings. Ten variables from the clinical and human factors literature were evaluated as potential modulators of provider alert acceptance. ORs were calculated for the impact of knowledge quality, alert display, textual information, prioritization, setting, patient age, dose-dependent toxicity, alert frequency, alert level, and required acknowledgment on acceptance of the DDI alert. Results 50 788 DDI alerts were analyzed. Providers accepted only 1.4% of non-interruptive alerts. For interruptive alerts, user acceptance positively correlated with frequency of the alert (OR 1.30, 95% CI 1.23 to 1.38), quality of display (4.75, 3.87 to 5.84), and alert level (1.74, 1.63 to 1.86). Alert acceptance was higher in inpatients (2.63, 2.32 to 2.97) and for drugs with dose-dependent toxicity (1.13, 1.07 to 1.21). The textual information influenced the mode of reaction and providers were more likely to modify the prescription if the message contained detailed advice on how to manage the DDI. Conclusion We evaluated potential modulators of alert acceptance by assessing content and human factors issues, and quantified the impact of a number of specific factors which influence alert acceptance. This information may help improve clinical decision support systems design. PMID:21571746

Frequent admitters to hospitals are high-cost patients who strain finite healthcare resources. However, the exact risk factors for frequent admissions, which can be used to guide risk stratification and design effective interventions locally, remain unknown. Our study aimed to identify the clinical and sociodemographic risk factors associated with frequent hospital admissions in Singapore. An observational study was conducted using retrospective 2014 data from the administrative database at Singapore General Hospital, Singapore. Variables were identified a priori and included patient demographics, comorbidities, prior healthcare utilisation, and clinical and laboratory variables during the index admission. Multivariate logistic regression analysis was used to identify independent risk factors for frequent admissions. A total of 16,306 unique patients were analysed and 1,640 (10.1%) patients were classified as frequent admitters. On multivariate logistic regression, 16 variables were independently associated with frequent hospital admissions, including age, cerebrovascular disease, history of malignancy, haemoglobin, serum creatinine, serum albumin, and number of specialist outpatient clinic visits, emergency department visits, admissions preceding index admission and medications dispensed at discharge. Patients staying in public rental housing had a 30% higher risk of being a frequent admitter after adjusting for demographics and clinical conditions. Our study, the first in our knowledge to examine the clinical risk factors for frequent admissions in Singapore, validated the use of public rental housing as a sensitive indicator of area-level socioeconomic status in Singapore. These risk factors can be used to identify high-risk patients in the hospital so that they can receive interventions that reduce readmission risk. Copyright: © Singapore Medical Association

Bleeding after percutaneous coronary intervention (PCI) is identified as a strong predictor for adverse events, including mortality. This study aims to compare the incidence and correlates of post-PCI bleeding across different clinical presentations. The study included 23,943 consecutive PCI patients categorized according to their clinical presentation: stable angina pectoris (n = 6,741), unstable angina pectoris (UAP) (n = 5,215), non-ST-segment elevation myocardial infarction (NSTEMI) (n = 8,418), ST-segment elevation myocardial infarction (STEMI) (n = 2,721), and cardiogenic shock (CGS) (n = 848). Severity of clinical presentation was associated with a greater use of preprocedural anticoagulation, glycoprotein IIb/IIIa inhibitors, and intraaortic balloon pump (IABP). TIMI-defined major bleeding increased with increasing severity of clinical presentation: stable angina pectoris, 0.7%; UAP, 1.0%; NSTEMI, 1.6%; STEMI, 4.6%; and CGS, 13.5% (P < .001). On multivariable analysis, CGS (odds ratio [OR], 4.67; 95% CI [2.62-8.34]), STEMI (OR, 3.39; 95% CI [2.07-5.55]), and NSTEMI (OR, 2.00; 95% CI [1.29-3.10]) remained correlated with major bleeding even after adjusting for baseline and procedural differences, whereas UAP did not. The multivariable model also identified the use of IABP, female gender, congestive heart failure, no prior PCI, increased baseline hematocrit, and increased procedure time as correlates for major bleeding. In patients undergoing PCI, the worsening severity of clinical presentation corresponds to an increase in incidence of post-PCI major bleeding. The increased risk with CGS, STEMI, and NSTEMI persisted despite adjusting for more aggressive pharmacotherapy and use of IABP. Careful attention to antithrombotic pharmacotherapy is warranted in this high-risk population. Copyright © 2014 Mosby, Inc. All rights reserved.

Necrotizing fasciitis is a life-threatening soft-tissue infection primarily involving the superficial fascia. The present report describes the clinical presentation and microbiological characteristics of this condition as well as the determinants of mortality associated with this uncommon surgical emergency. The medical records of eighty-nine consecutive patients who had been admitted to our institution for necrotizing fasciitis from January 1997 to August 2002 were reviewed retrospectively. The paucity of cutaneous findings early in the course of the disease makes the diagnosis difficult, and only thirteen of the eighty-nine patients had a diagnosis of necrotizing fasciitis at the time of admission. Preadmission treatment with antibiotics modified the initial clinical picture and often masked the severity of the underlying infection. Polymicrobial synergistic infection was the most common cause (forty-eight patients; 53.9%), with streptococci and enterobacteriaceae being the most common isolates. Group-A streptococcus was the most common cause of monomicrobial necrotizing fasciitis. The most common associated comorbidity was diabetes mellitus (sixty-three patients; 70.8%). Advanced age, two or more associated comorbidities, and a delay in surgery of more than twenty-four hours adversely affected the outcome. Multivariate analysis showed that only a delay in surgery of more than twenty-four hours was correlated with increased mortality (p < 0.05; relative risk = 9.4). Early operative débridement was demonstrated to reduce mortality among patients with this condition. A high index of suspicion is important in view of the paucity of specific cutaneous findings early in the course of the disease.

Epilepsy is a chronic illness that requires a long-term periodic follow-up of the patient and this means that as time goes by the number of patients attended increases, with the ensuing added cost for the healthcare system. To determine the factors involved in the time until an epileptic patient's next visit. Our sample consisted of a selection of patients who visited the epilepsy clinic at our hospital consecutively during one year. Their clinical situation and relationship with the medical advice they were given, together with the factors involved in the time elapsed until the next visit, were analysed by means of predictive econometric models. There is a clear association between the patient's clinical situation and the modification of the treatment proposed by the neurologist in the previous visit. The factors involved in the time until the next visit were the frequency of seizures, adverse side effects from medicines -above all those that affect cognition- and the medical advice given to the patient. Polytherapy, psychoaffective disorders or the patient's social situation were not found to be significant. Follow-up visits in a specific epilepsy clinic improves the patient's situation. This is the first analysis of the demand for healthcare in patients with epilepsy conducted by means of econometric methods and from a mixed physician-patient perspective. Since the factors that determine the time until the next visit can be modified, the number of visits per year could be reduced, thus improving patients' clinical situation. We suggest a greater amount of time should be spent per visit so as to be able to have a bearing on it and thereby cut costs in the long term.

Prognostic features and clinical presentation of acute idiopathic enterocolitis in horses

Clinical and hematological changes observed on presentation of 47 horses referred to the Ontario Veterinary College with acute idiopathic colitis were analyzed for their prognostic features. Cases of acute enterocolitis were characterized by fever, dehydration, abnormalities of serum electrolyte concentrations, azotemia, hypoalbuminemia, and increased serum concentrations of muscle enzymes. Severely dehydrated horses were seven times more likely to die or be euthanized than those that were not dehydrated. Other factors associated with failure to survive included the following: increased hematocrit, increased number of band neutrophils, increased serum creatinine and urea concentrations, and decreased blood pH and increasingly negative base excess. The results of multivariate variable analysis (stepwise logistic regression) suggested that, among the variables tested, base excess was the best predictor of death or survival. Twenty of 47 horses died or were euthanized. Reasons for death or euthanasia included: severe disseminated intravascular coagulation, unresponsiveness of severe metabolic acidosis and hypoproteinemia to treatments, and severity of colonic lesions on exploratory laparotomy. Of the surviving horses, three developed chronic laminitis (two were destroyed) and five developed jugular vein thrombosis. Fourteen of 16 horses for which subsequent histories were available returned to normal function. Early recognition of the disease, combined with early and aggressive correction of dehydration and of acid-base imbalance, may be important determinants of survival in horses with acute idiopathic colitis.

The objectives were to determine the prevalence of atypical presentations among older adults at the Emergency Department (ED) of a tertiary care hospital and to identify factors associated with these presentations. A retrospective medical record audit was randomly reviewed in 633 patients who were aged ≥ 65 years who attended the ED of Srinagarind Medical School Hospital in 2013. Demographic data were collected and were analyzed using descriptive statistics. Regression analysis was used to analyze the variables associated with the outcomes. The prevalence of an atypical presentation was 28.6% (181/633 cases). The failure to develop fever with a disease known to cause fever was the most common atypical presentation of illness (34.42%). Independent factors associated with atypical presentations were complicated urinary tract infection (UTI) (odds ratios (OR) 4.66, 95% confidence interval (CI) 2.0, 10.84, p=0.00) and a background of dementia (OR 3.48, 95% CI 1.38, 8.77, p=0.008). The prevalence of atypical presentations of older adults at the ED was about a third. The absence of fever with a disease known to cause fever was the most common atypical presentation. Complicated UTI and demented patients were the independent risk factors associated with the atypical presentations. Early awareness of non-specific presentations and applying comprehensive geriatric assessments among older patients at the ED is recommended. Copyright © 2015 Elsevier Ireland Ltd.

Temporal shifts in clinical presentation and underlying mechanisms of atherosclerotic disease.

PubMed

Pasterkamp, Gerard; den Ruijter, Hester M; Libby, Peter

2017-01-01

The concept of the 'vulnerable plaque' originated from pathological observations in patients who died from acute coronary syndrome. This recognition spawned a generation of research that led to greater understanding of how complicated atherosclerotic plaques form and precipitate thrombotic events. In current practice, an increasing number of patients who survive their first event present with non-ST-segment elevation myocardial infarction (NSTEMI) rather than myocardial infarction (MI) with ST-segment elevation (STEMI). The culprit lesions that provide the pathological substrate for NSTEMI can vary considerably from the so-called 'vulnerable plaque'. The shift in clinical presentation of MI and stroke corresponds temporally to a progressive change in the characteristics of human plaques away from the supposed characteristics of vulnerability. These alterations in the structure and function of human atherosclerotic lesions might mirror the modifications that are produced in experimental plaques by lipid lowering, inspired by the vulnerable plaque construct. The shift in the clinical presentations of the acute coronary syndromes mandates a critical reassessment of the underlying mechanisms, proposed risk scores, the results and interpretation of preclinical experiments, as well as recognition of the limitations of the use of population data and samples collected before the application of current preventive interventions.

To evaluate the clinical anatomy and presentations of congenital portosystemic shunts, and determine features that promote recognition on imaging. Institutional review board approval was obtained for this HIPAA-compliant study. The requirement for written informed consent was waived. Radiology reports were retrospectively reviewed from non-cirrhotic patients who underwent imaging studies from January 1999 through February 2009. Clinical sources reviewed included electronic medical records, archived images and histopathological material. Eleven patients with congenital portosystemic shunts were identified (six male and five female; age range 20 days to 84 years). Seven patients had extrahepatic and four patients had intrahepatic shunts. All 11 patients had absent or hypoplastic intrahepatic portal veins, a feature detected by CT and MRI, but not by US. Seven patients presented with shunt complications and four with presentations unrelated to shunt pathophysiology. Three adult patients had four splenic artery aneurysms. Prospective radiological evaluation of five adult patients with cross-sectional imaging had failed prospectively to recognize the presence of congenital portosystemic shunts on one or more imaging examinations. Congenital portosystemic shunts are associated with splenic artery aneurysms, a previously unrecognized association. Portosystemic shunts were undetected during prospective radiologic evaluation in the majority of adult patients, highlighting the need to alert radiologists to this congenital anomaly.

Exploring Factors Affecting Voluntary Adoption of Electronic Medical Records Among Physicians and Clinical Assistants of Small or Solo Private General Practice Clinics.

Or, Calvin; Tong, Ellen; Tan, Joseph; Chan, Summer

2018-05-29

The health care reform initiative led by the Hong Kong government's Food and Health Bureau has started the implementation of an electronic sharing platform to provide an information infrastructure that enables public hospitals and private clinics to share their electronic medical records (EMRs) for improved access to patients' health care information. However, previous attempts to convince the private clinics to adopt EMRs to document health information have faced challenges, as the EMR adoption has been voluntary. The lack of electronic data shared by private clinics carries direct impacts to the efficacy of electronic record sharing between public and private healthcare providers. To increase the likelihood of buy-in, it is essential to proactively identify the users' and organizations' needs and capabilities before large-scale implementation. As part of the reform initiative, this study examined factors affecting the adoption of EMRs in small or solo private general practice clinics, by analyzing the experiences and opinions of the physicians and clinical assistants during the pilot implementation of the technology, with the purpose to learn from it before full-scale rollout. In-depth, semistructured interviews were conducted with 23 physicians and clinical assistants from seven small or solo private general practice clinics to evaluate their experiences, expectations, and opinions regarding the deployment of EMRs. Interview transcripts were content analyzed to identify key factors. Factors affecting the adoption of EMRs to record and manage health care information were identified as follows: system interface design; system functions; stability and reliability of hardware, software, and computing networks; financial and time costs; task and outcome performance, work practice, and clinical workflow; physical space in clinics; trust in technology; users' information technology literacy; training and technical support; and social and organizational influences.

Candida species are the leading cause of invasive fungal infections in children admitted to hospital. However, few data exist with regard to the clinical features, risk factors and prognosis for candidemia in neonates. The present retrospective study included 40 neonates from the Affiliated Children's Hospital of the Capital Institute of Pediatrics (Beijing, China) in the time period between January 1, 2006 and December 31, 2010 (candidemia group, n=19; non-candidemia group, n=21). The clinical characteristics, prognosis and previously identified risk factors for the two groups were recorded. According to the forward stepwise multivariate logistic regression analysis, administration of antibiotics >2 weeks prior, the use of glycopeptide antibiotics, maternal candidal vaginitis and secondary gastrointestinal surgery were identified as predictors of candidiasis. When compared with the non-gastrointestinal dysfunction group, the proportion of neonates that had been subjected to parenteral nutrition, central venous catheters, gastrointestinal surgery, secondary gastrointestinal surgery, repeated tracheal intubation and glycopeptide antibiotic administration was significantly higher in the gastrointestinal dysfunction group (P<0.05). Long-term application of antibiotics, use of glycopeptide antibiotics, maternal candidal vaginitis and secondary gastrointestinal surgery appeared to be the risk factors of candidemia in neonates. The neonates co-existed with gastrointestinal dysfunction suffering from candidemia were likely to experience growth retardation at 6 months after hospital discharge. Candidemia is potentially life-threatening situation for neonates, and if patients do not succumb it may affect their early development. PMID:26622453

The study objective was to determine the nutritional status and its association with sociodemographic characteristics and health complaints of older persons presenting at the General Outpatients Department (GOPD) Clinic of University College Hospital (UCH), Ibadan, Nigeria. A cross-sectional descriptive design was used to select 500 consecutively presenting participants aged 60 years and older between September and December, 2009. The Mini-Nutritional Assessment (MNA) tool and body mass index were used to assess undernutrition and overweight, respectively. The prevalence of nutritional problems was 61.9% (undernutrition = 7.8% and overweight = 54.1%). Being unmarried (P < 0.001), engagement in a job after the age of 60 years (P < 0.001), constipation (P = 0.009), rectal bleeding (P = 0.008), and oral problems (mouth, teeth, and tongue) were significantly (P < 0.001) associated with undernutrition. Younger age (P = 0.050) and female gender (P = 0.011) were significantly associated with being overweight. Logistic regression analysis showed being unmarried OR = 1.355 (95%CI 1.075-1.708) to be the most important factor for the development of undernutrition. The high prevalence of nutritional problems in this study underscores the need for intervention in this population. Correlation analysis (Pearson's) showed a positive association between BMI and MNA scores (r = 0.152, P = 0.001).

Clinical supervision is important for effective health service delivery, professional development and practice. Despite its importance there is a lack of evidence regarding the factors that improve its quality. This study aimed to investigate the factors that influence the quality of clinical supervision of occupational therapists employed in a large public sector health service covering mental health, paediatrics, adult physical and other practice areas. A mixed method, sequential explanatory study design was used consisting of two phases. This article reports the quantitative phase (Phase One) which involved administration of the Manchester Clinical Supervision Scale (MCSS-26) to 207 occupational therapists. Frequency of supervision sessions, choice of supervisor and the type of supervision were found to be the predictor variables with a positive and significant influence on the quality of clinical supervision. Factors such as age, length of supervision and the area of practice were found to be the predictor variables with a negative and significant influence on the quality of clinical supervision. Factors that influence the perceived quality of clinical supervision among occupational therapists have been identified. High quality clinical supervision is an important component of clinical governance and has been shown to be beneficial to practitioners, patients and the organisation. Information on factors that make clinical supervision effective identified in this study can be added to existing supervision training and practices to improve the quality of clinical supervision. © 2016 Occupational Therapy Australia.

During initial assessment of individuals with schizophrenia and related disorders (schizophrenia spectrum disorders [SSDs]), clinicians tend to pay greater attention to psychotic symptoms than mood symptoms, including depression. Depression is reported to influence the course of SSDs, but not much is known about the risk factors for depression in SSDs. In the present study, we examined clinical predictors of depression in SSDs. The sample included 71 patients with SSDs followed in a modified Assertive Community Treatment program, the Community Support Network of Springfield, Illinois. The study design was naturalistic, prospective, and longitudinal (mean follow-up = 8.3 years; SD = 7.3). The GENMOD procedure appropriate for repeated measures analysis with dichotomous outcome variables followed longitudinally was computed. Rates of depression ranged from 18% to 41% over the differing assessment periods. Schizophrenia and schizoaffective disorder did not vary by depression rate. Depression independent of SSD diagnosis was associated with greater hospitalization rates. Clinical variables predict- ing depression were auditory hallucinations, delusions, poor insight, and poor judgment. Psychotic symptoms in the course of SSDs are risk factors for depression. As a consequence, the mental status examination of patients with SSDs with active psychosis should include assessment of mood changes. Further research is warranted to determine if treatment of depression among patients with SSDs may reduce their rates of hospitalization.

Clinical education is an extremely important process in cultivating healthcare professionals, and the quality of educators has a major impact on the quality of future practitioners. Although practicing clinical midwives contribute to the education of pre-registered midwives and those qualified within the past year (new midwives), the factors defining the educational competencies of clinical midwives have not been clarified. The purpose of this study was to explore the factors that define the mentoring competencies of clinical midwives involved in educating new midwives. An exploratory quantitative research study. Questionnaires were distributed to 694 midwives who had previously conducted educational activities with new midwives at the 63 facilities whose administrator or nurse manager in charge of all staff, including midwives, consented to participate. Of the 694 midwives, 464 (66.9%) returned the questionnaire and 451 (65.1%) valid responses were analyzed. Exploratory factor analyses were performed on the following three concepts: [competency as a professional], [competency as an educator], and [personal characteristics]. [Competency as a professional] consisted of two factors: and ; [competency as an educator] consisted of four factors: , , and ; and [personal characteristics consisted of three factors: , and . These three concepts were defined by a total of nine sub-concepts (factors), and 41 items were extracted with a reliability coefficient (Cronbach's α) of 0.944 CONCLUSIONS: "Mentoring competencies of clinical midwives (MCCM)" are defined by three concepts and nine sub-concepts, which can be evaluated by 41 items regarding

There is a paucity of research on patients presenting with uninfected diabetic foot ulcers (DFU) that go on to develop infection. We aimed to investigate the incidence and risk factors for developing infection in a large regional cohort of patients presenting with uninfected DFUs. We performed a secondary analysis of data collected from a validated prospective state-wide clinical diabetic foot database in Queensland (Australia). Patients presenting for their first visit with an uninfected DFU to a Diabetic Foot Service in one of thirteen Queensland regions between January 2012 and December 2013 were included. Socio-demographic, medical history, foot disease history, DFU characteristics and treatment variables were captured at the first visit. Patients were followed until their DFU healed, or if their DFU did not heal for 12-months, to determine if they developed a foot infection in that period. Overall, 853 patients were included; mean(standard deviation) age 62.9(12.8) years, 68.0% male, 90.9% type 2 diabetes, 13.6% indigenous Australians. Foot infection developed in 342 patients for an overall incidence of 40.1%; 32.4% incidence in DFUs healed <3 months, 55.9% in DFUs healed between 3-12 months (p<0.05). Independent risk factors (Odds Ratio (95% confidence interval)) for developing infection were: DFUs healed between 3-12 months (2.3 (1.6-3.3)), deep DFUs (2.2 (1.2-3.9)), peripheral neuropathy (1.8 (1.1-2.9)), previous DFU history (1.7 (1.2-2.4)), foot deformity (1.4 (1.0-2.0)), female gender (1.5 (1.1-2.1)) and years of age (0.98 (0.97-0.99)) (all p<0.05). A considerable proportion of patients presenting with an uninfected DFU will develop an infection prior to healing. To prevent infection clinicians treating patients with uninfected DFUs should be particularly vigilant with those presenting with deep DFUs, previous DFU history, peripheral neuropathy, foot deformity, younger age, female gender and DFUs that have not healed by 3 months after presentation.

Understanding the phenomenon of nursing student empowerment in clinical practice is important. Investigating the cognition of empowerment and identifying predictors are necessary to enhance nursing student empowerment in clinical practice. To identify empowerment predictors for Korean nursing students in clinical practice based on studies by Bradbury-Jones et al. and Spreitzer. A cross-sectional design was used for this study. This study was performed in three nursing colleges in Korea, all of which had similar baccalaureate nursing curricula. Three hundred seven junior or senior nursing students completed a survey designed to measure factors that were hypothesized to influence nursing student empowerment in clinical practice. Data were collected from November to December 2011. Study variables included self-esteem, clinical decision making, being valued as a learner, satisfaction regarding practice with a team member, perception on professor/instructor/clinical preceptor attitude, and total number of clinical practice fields. Data were analyzed using stepwise multiple regression analyses. All of the hypothesized study variables were significantly correlated to nursing student empowerment. Stepwise multiple regression analysis revealed that clinical decision making in nursing (t=7.59, p<0.001), being valued as a learner (t=6.24, p<0.001), self-esteem (t=3.62, p<0.001), and total number of clinical practice fields (t=2.06, p=0.040). The explanatory power of these predictors was 35% (F=40.71, p<0.001). Enhancing nursing student empowerment in clinical practice will be possible by using educational strategies to improve nursing student clinical decision making. Simultaneously, attitudes of nurse educators are also important to ensure that nursing students are treated as valued learners and to increase student self-esteem in clinical practice. Finally, diverse clinical practice field environments should be considered to enhance experience. Copyright © 2015 Elsevier Ltd

To briefly review the clinical presentation and diagnosis of patients with primary brain tumors, followed by an in-depth survey of the pertinent pharmacotherapy. A detailed search of the neurologic, neurosurgical, and oncologic literature for basic science research, clinical studies, and review articles related to chemotherapy and pharmacotherapy of primary brain tumors. Relevant studies on tissue culture systems, animals, and humans examining the mechanisms of action, pharmacokinetics, clinical pharmacology, and treatment results of chemotherapeutic agents for primary brain tumors. In addition, studies of pharmacologic agents administered for supportive care and symptom control are reviewed. Primary brain tumors derive from cells within the intracranial cavity and generally present with headache, seizure activity, cognitive changes, and weakness. They are diagnosed most efficiently with magnetic resonance imaging. After diagnosis, the most common supportive medications include corticosteroids, gastric acid inhibitors, and anticonvulsants. Chemotherapy is adjunctive treatment for patients with malignant tumors and selected recurrent or progressive benign neoplasms. In general, the most effective chemotherapeutic drugs are alkylating agents such as the nitrosoureas, procarbazine, cisplatin, and carboplatin. Other agents used include cyclophosphamide, methotrexate, vincristine, and etoposide. Angiogenesis inhibitors and gene therapy comprise some of the novel therapeutic strategies under investigation. The efficacy of chemotherapy for primary brain tumors remains modest. Novel agents must be discovered that are more specific and attack tumor cells at the molecular level of tumorigenesis. Furthermore, strategies must be developed to counteract the pervasive problem of brain tumor chemoresistance.

Clinical trial globalization is a major trend for industry-sponsored clinical trials. There has been a shift in clinical trial sites towards emerging regions of Eastern Europe, Latin America, Asia, the Middle East, and Africa. Our study objectives were to evaluate the current characteristics of clinical trials and to find out the associated multiple factors which could explain clinical trial globalization and its implications for clinical trial globalization in 2011-2013. The data elements of "phase," "recruitment status," "type of sponsor," "age groups," and "design of trial" from 30 countries were extracted from the ClinicalTrials.gov website. Ten continental representative countries including the USA were selected and the design elements were compared to those of the USA. Factors associated with trial site distribution were chosen for a multilinear regression analysis. The USA, Germany, France, Canada, and United Kingdom were the "top five" countries which frequently held clinical trials. The design elements from nine continental representative countries were quite different from those of the USA; phase 1 trials were more prevalent in India (OR 1.517, p < 0.001) while phase 3 trials were much more prevalent in all nine representative countries than in the USA. A larger number of "child" age group trials was performed in Poland (OR 1.852, p < 0.001), Israel (OR 1.546, p = 0.005), and South Africa (OR 1.963, p < 0.001) than in the USA. Multivariate analysis showed that health care expenditure per capita, Economic Freedom Index, Human Capital Index, and Intellectual Property Rights Index could explain the variance of regional distribution of clinical trials by 63.6%. The globalization of clinical trials in the emerging regions of Asia, South Africa, and Eastern Europe developed in parallel with the factors of economic drive, population for recruitment, and regulatory constraints.

Leukaemia is the most common cancer of childhood, accounting for a third of cases. In order to assist clinicians in its early detection, we systematically reviewed all existing data on its clinical presentation and estimated the frequency of signs and symptoms presenting at or prior to diagnosis. We searched MEDLINE and EMBASE for all studies describing presenting features of leukaemia in children (0-18 years) without date or language restriction, and, when appropriate, meta-analysed data from the included studies. We screened 12 303 abstracts for eligibility and included 33 studies (n=3084) in the analysis. All were cohort studies without control groups. 95 presenting signs and symptoms were identified and ranked according to frequency. Five features were present in >50% of children: hepatomegaly (64%), splenomegaly (61%), pallor (54%), fever (53%) and bruising (52%). An additional eight features were present in a third to a half of children: recurrent infections (49%), fatigue (46%), limb pain (43%), hepatosplenomegaly (42%), bruising/petechiae (42%), lymphadenopathy (41%), bleeding tendency (38%) and rash (35%). 6% of children were asymptomatic on diagnosis. Over 50% of children with leukaemia have palpable livers, palpable spleens, pallor, fever or bruising on diagnosis. Abdominal symptoms such as anorexia, weight loss, abdominal pain and abdominal distension are common. Musculoskeletal symptoms such as limp and joint pain also feature prominently. Children with unexplained illness require a thorough history and focused clinical examination, which should include abdominal palpation, palpation for lymphadenopathy and careful scrutiny of the skin. Occurrence of multiple symptoms and signs should alert clinicians to possible leukaemia. Published by the BMJ Publishing Group Limited.

The clinical learning environment is a complex social entity that influences student learning outcomes in the clinical setting. Students can experience the clinical learning environment as being both facilitative and obstructive to their learning. The clinical environment may be a source of stress, creating feelings of fear and anxiety which in turn affect the students' responses to learning. Equally, the environment can enhance learning if experienced positively. This study described pupil enrolled nurses' experiences of facilitative and obstructive factors in military and public health clinical learning settings. Using a qualitative, contextual, exploratory descriptive design, three focus group interviews were conducted until data saturation was reached amongst pupil enrolled nurses in a military School of Nursing. Data analysed provided evidence that acceptance by clinical staff and affordance of self-directed learning facilitated learning. Students felt safe to practise when they were supported by the clinical staff. They felt a sense of belonging when the staff showed an interest in and welcomed them. Learning was obstructed when students were met with condescending comments. Wearing of a military uniform in the public hospital and horizontal violence obstructed learning in the clinical learning environment. Students cannot have effective clinical preparation if the environment is not conducive to and supportive of clinical learning, The study shows that military nursing students experience unique challenges as they are trained in two professions that are hierarchical in nature. The students experienced both facilitating and obstructing factors to their learning during their clinical practice. Clinical staff should be made aware of factors which can impact on students' learning. Policies need to be developed for supporting students in the clinical learning environment.

The present study aimed to assess the prevalence of otitis media and risk-factors for sensorineural hearing loss among infants in the Solomon Islands, in order to recommend an Infant Ear and Hearing Program that would be suitable to the Pacific Island context. Ear examinations and the JCIH Risk-Factor Questionnaire were administered to 288 infants attending Child Welfare Clinics in the Solomon Islands. Overall, 150 infants (52.084%) presented with bilateral normal ear examinations and no risk-factors for SNHL. There were 73 infants (25.34%) with ear pathology in at least one ear, 13 (4.5%) of whom required referral to the ENT Clinic for medical management. The most common pathology was otitis media with effusion (OME) (21.87%). Infants aged 7-12 months were significantly more likely to present with OME (p<0.001) and a history of otitis media (p=0.017) than infants aged 0-6 months. There were 71 infants (24.65%) with at least one risk-factor for sensorineural hearing loss. The most common risk-factors were ototoxicity (8.3%), non-elective caesarean delivery (6.59%), and possible in-utero syphilis infection (5.55%). The prevalence of otitis media and risk-factors for sensorineural hearing loss indicate the importance of initiating Infant Ear and Hearing Programs in the Solomon Islands. Program should facilitate early education on prevention of ear disease, as well as early diagnosis and management of children with hearing loss. Copyright © 2018. Published by Elsevier B.V.

Non-suicidal self-injury: clinical presentation, assessment and management.

Dhingra, Katie; Ali, Parveen

2016-09-28

Non-suicidal self-injury is a common behaviour in adolescents and young adults, and may be associated with mental health disorders, risk of suicidal behaviour (ideation and attempts), and a need for clinical services. Nurses, in particular those working in emergency departments and mental health settings, have a crucial role in the assessment, treatment and care of individuals who have self-injured. It is essential for nurses to assess an individual's risk of more serious harm or accidental death, regardless of intent. It is also important to understand the variations in non-suicidal self-injurious behaviour in terms of its presentation, features and functions, to provide appropriate person-centred care. Nurses should assist individuals in identifying the triggers or cues for their behaviour, exploring treatment options, and monitoring their behaviour and risk in the long term. This article describes the profile of people who self-injure, and the issues related to assessment and management of such patients presenting in emergency departments. A description of who self-injures and why, and how people self-injure; developmental aspects of these behaviours, including short and long-term outcomes; and the available treatments is presented.

Congenital portosystemic veno-venous malformations are rare abnomalities that often remain undiagnosed. Typically they are classified by their anatomical characteristics according to Morgan (extrahepatic, Abernethy malformations type Ia,b and II) and Park (intrahepatic, types 1-4). However, their clinical presentation is less dependent on the anatomical type. We reviewed the clinical characteristics of six cases drawn from our files (from 1970 to 2006). One patient, a 25-year-old male, had extrahepatic shunting whereby the liver receives only arterial blood because the portal vein (PV) connects with the inferior caval vein (ICV) (Abernethy Ib); he presented with episodes of jaundice and pruritus. Three patients had extrahepatic shunting with patent intrahepatic portal veins, but with shunting of splenomesenterial blood towards the ICV (Abernethy II); these included a 66-year-old male with hepatic encephalopathy, a 17-year-old female with (porto?-)pulmonary hypertension without portal hypertension, and a 33-year-old female with epidsodes of acute pain secondary to spontaneous bleeding within a primary liver tumor. Two patients had intrahepatic shunting; these included an 8-year-old boy who was diagnosed incidentally during work-up for abnormal liver enzymes with a communication between right PV and ICV (Park type 1), and a 59-year-old male with multiple PV-ICV-shunts in several liver segments (Park, type 4) who presented with hepatic encephalopathy. Patients often present with signs of hepatic shunting (encephalopathy, pulmonary hypertension, hepatopulmonary syndrome, and/or hypoglycemia) with relative sparing of the synthetic liver function in the absence of portal hypertension. Some shunts present with space-occupying lesions (focal nodular hyperplasia, hepatocellular carcinoma, nodular regenerative hyperplasia, etc.) or biliary atresia. Finally, some cases are detected incidentally.

Patterns of clinical presentation of adult coeliac disease in a rural setting.

In recent years there has been increasing recognition that the pattern of presentation of coeliac disease may be changing. The classic sprue syndrome with diarrhoea and weight loss may be less common than the more subtle presentations of coeliac disease such as an isolated iron deficiency anaemia. As a result, the diagnosis of this treatable condition is often delayed or missed. Recent serologic screening tests allow non-invasive screening to identify most patients with the disease and can be applied in patients with even subtle symptoms indicative of coeliac disease. Both benign and malignant complications of coeliac disease can be avoided by early diagnosis and a strict compliance with a gluten free diet. The aim of this study is to evaluate the trends in clinical presentation of patients diagnosed with adult coeliac disease. In addition, we studied the biochemical and serological features and the prevalence of associated conditions in patients with adult coeliac disease. This is an observational, retrospective, cross-sectional review of the medical notes of 32 adult patients attending the specialist coeliac clinic in a district general hospital. Anaemia was the most common mode of presentation accounting for 66% of patients. Less than half of the patients had any of the classical symptoms of coeliac disease and 25% had none of the classical symptoms at presentation. Anti-gliadin antibodies, anti-endomysial antibody and anti-tissue transglutaminase showed 75%, 68% and 90% sensitivity respectively. In combination, serology results were 100% sensitive as screening tests for adult coeliac disease. Fifty nine percent patients had either osteoporosis or osteopenia. There were no malignant complications observed during the follow up of our patients. Most adults with coeliac disease have a sub clinical form of the disease and iron deficiency anaemia may be its sole presenting symptom. Only a minority of adult coeliac disease patients present with classical mal

Clinical pictures of unknown origin in neurology: past, present and future usefulness of artificial intelligence.

Although, in the course of the last 50 years, the achievements in the medical field have been astonishing, at the beginning of the third millennium a number of clinical pictures are still left without a precise nosographic origin. In the past, the delay in scientific communication was the main explanation presented for the lack of understanding of clinical pictures of unknown nosographic origin. The history of medicine provides excellent examples of this dispersion of human capital, even if the history of clinical neurology presents "exceptions" (the pictures that we now call de la Tourette's syndrome and Parkinson's disease) that indicate that major clinical syndromes could be clearly detected and relatively rapidly diffused even in the 19th century. Contrary to the past, the delay in scientific communication no longer seems an obstacle to the sharing of medical knowledge. Nevertheless, the problem of the in-depth comprehension of clinical pictures of unknown nosographic origin still remains dominant, mainly because of the limited spread of ample and flexible online accessible databases of unknown nosographic origin clinical syndromes. The need for interactive electronic archives and other artificial intelligence resources in order to promote progress in clinical knowledge is discussed in this paper.

To evaluate the prevalence, clinical features, and risk factors of dentin hypersensitivity (DH) in a Brazilian population. 300 patients at the Dentistry Clinic of the University of São Paulo participated in this study. The subjects completed a questionnaire regarding their personal information, the presence of DH, and some of its risk factors. Following completion of the questionnaire, a clinical examination was undertaken. To confirm the presence of DH, the subjects were evaluated with the use of a probe and cold air from a triple syringe. Statistical analysis was performed with the chi-square test and odds ratio, with the critical level p <0.05. The prevalence of DH was 46%. Females presented a higher prevalence than males (p <0.05). The left posterior region was affected by DH the most (maxilla = 41% and mandible = 36%). Cold was reported as the most common pain-inducing stimulus (88%). The pain was described as "discomfort" by 51% of the subjects with DH. Toothbrushing four times a day (p <0.05), toothbrushing with excessive force (p <0.05), bruxism (p <0.05), and gastroesophageal reflux (p <0.05) were strongly correlated with DH. The prevalence of DH was particularly high. The risk factors for DH were gender (female), toothbrushing four times a day, toothbrushing with excessive force, bruxism, and gastroesophageal reflux. DH was a common finding in this population suggesting that preventive measures considering its risk factors must be implemented in order to reduce or control the symptoms.

Community-acquired pneumonia (CAP) is diagnosed on the basis of a suggestive history and compatible physical findings and new infiltrates on a chest radiograph. No criteria or combination of criteria based on history and physical examination have been found to be gold standard. With the rise in elderly Gulf Cooperation Council (GCC) residents, CAP is likely to present with non-classical manifestations such as somnolence, new anorexia, and confusion and carries a worse outcome than CAP in their younger counterparts. Tuberculosis should be considered in the differential diagnosis of unresolving CAP in the GCC region. Diagnostic work up depends on severity of CAP, clinical course and underlying risk factors.

Most of the available literature on ST-Elevated myocardial infarction (STEMI) in women was conducted in the developed world and data from Middle-East countries was limited. To examine the clinical presentation, patient management, quality of care, risk factors and in-hospital outcomes of women with acute STEMI compared with men using data from a large STEMI registry from the Middle East. Data were derived from the third Gulf Registry of Acute Coronary Events (Gulf RACE-3Ps), a prospective, multinational study of adults with acute STEMI from 36 hospitals in 6 Middle-Eastern countries. The study included 2928 patients; 296 women (10.1%) and 2632 men (89.9%). Clinical presentations, management and in-hospital outcomes were compared between the 2 groups. Women were 10 years older and more likely to have diabetes mellitus, hypertension, and hyperlipidemia compared with men who were more likely to be smokers (all p<0.001). Women had longer median symptom-onset to emergency department (ED) arrival times (230 vs. 170 min, p<0.001) and ED to diagnostic ECG (8 vs. 6 min., p<0.001). When primary percutaneous coronary intervention (PPCI) was performed, women had longer door-to-balloon time (DBT) (86 vs. 73 min., p=0.009). When thrombolytic therapy was not administered, women were less likely to receive PPCI (69.7 vs. 76.7%, p=0.036). The mean duration of hospital stay was longer in women (6.03 ± 22.51 vs. 3.41 ± 19.45 days, p=0.032) and the crude in-hospital mortality rate was higher in women (10.4 vs. 5.2%, p<0.001). However, after adjustments, multivariate analysis revealed a statistically non-significant trend of higher in-hospital mortality among women than men (6.4 vs. 4.6%), (p=0.145). Our study demonstrates that women in our region have almost double the mortality from STEMI compared with men. Although this can partially be explained by older age and higher risk profiles in women, however, correction of identified gaps in quality of care should be attempted to reduce

The digital sucking habit have been significantly related with the malocclusions. These problems can be observed as in the deciduous and mixed as in the permanent dentition. Frequency, length, and intensity of the habit generate as a consequence: anterior open bite, retrusion of the mandible, protrusion of the maxilla, excessive overjet, labial version of the upper incisors, uprighting of the lower incisors, posterior cross bites, sometimes associated to a ogival palate, diastema between the upper incisors, and any others facial characteristics. According to various authors, when the habit persist for an extended period after the age of four years, is considered how malocclusion cause. In this case is requered the professional interference. The presentation of this study has the objective to show the clinic conduct for preventive orthodontics in face to cases who exhib harmful habits.

Is there a reliable factorial structure in the 20-item Toronto Alexithymia Scale? A comparison of factor models in clinical and normal adult samples.

The 20-item Toronto Alexithymia Scale (TAS-20) is the most widely used instrument for measuring alexithymia. However, different studies did not always yield identical factor structures of this scale. The present study aims at clarifying some discrepant results. Maximum likelihood confirmatory factor analyses of a German version of the TAS-20 were conducted on data from a clinical sample (N=204) and a sample of normal adults (N=224). Five different models with one to four factors were compared. A four-factor model with factors (F1) "Difficulty identifying feelings" (F2), "Difficulty describing feelings" (F3), "Low importance of emotion" and (F4) "Pragmatic thinking" and a three-factor model with the combined factor "Difficulties in identifying and describing feelings" described the data best. Factors related to "externally oriented thinking" provided no acceptable level of reliability. Results from the present and other studies indicate that the factorial structure of the TAS-20 may vary across samples. Whether factor structures different from the common three-factor structure are an exception in some mainly clinical populations or a common phenomenon outside student populations has still to be determined. For a further exploration of the factor structure of the TAS-20 in different populations, it would be important not only to test the fit of the common three-factor model, but also to consider other competing solutions like the models of the present study.

The aim of this study was to examine the prevalence and severity of caries experience (CE) in 4-6 year-olds attending dental clinics in Kinshasa, DR Congo, and to explore possible associations with reported behavioural and socio-demographic factors. A convenience sample of children attending five dental clinics was recruited. Carers, usually parents, completed a questionnaire consisting of socio-demographic information, oral health and tobacco consumption profile of parents, socio-economic family situation and oral health habits of the child. Children were clinically examined using WHO criteria by trained dentist-examiners. To investigate factors associated with CE, multivariate logistic regression was applied with the significance level set at 0.05. Some 158 children with mean age 5.3 (sd 0.7) years were recruited; 80% presented with clinical signs of CE. Between-meal snacking and drinking was reported by 78% and 65%; 35% had sugar-containing drinks. Most (81%) brushed once a day and 82% brushed in the morning. Prevalence of CE was associated with gender, frequency of meals, consumption of drinks during meals and consumption of sugar-containing drinks; severity with type of infant feeding and sugar-content of the last meal at night. The present study shows that both prevalence and severity of caries experience were associated with reported dietary habits, confirming the importance of preventive interventions dealing with these habits in young children living in a developing country.

[Epidemiology and Clinical Presentation of Sarcoidosis].

Costabel, U; Wessendorf, T E; Bonella, F

2017-06-01

Sarcoidosis is a systemic disease of unknown aetiology. Typical histology shows epithelioid cell granulomas, and typical immunopathology enhanced Th1 type immune responses in the involved organs. The disease occurs worldwide, but more frequently in northern countries than in the south. In Germany, the incidence is estimated to be 10 per 100,000, and the prevalence 44-48 per 100,000. Sarcoidosis usually affects adults under 50 years of age, but can also be seen in children, adolescents and in the elderly. Women are more frequently affected than men. Familial clusters can occur. The clinical presentation of sarcoidosis varies widely and depends on the manifestations in the individual organ. Systemic symptoms include fatigue, night sweats, weight loss, fever, arthralgia and myalgia. Organ-specific symptoms include cough and dyspnoea, with pulmonary involvement, headache and palsy in neurosarcoidosis, arrhythmias and heart failure in cardiac sarcoidosis, and manifold skin lesions with skin involvement. Relapses are rarely seen in acute sarcoidosis, whereas the chronic form tends to relapse more frequently. Löfgren's syndrome, a specific phenotype of acute sarcoidosis, is characterised by bihilar lymphadenopathy, ankle arthritis and erythema nodosum. Chronic sarcoidosis can be asymptomatic, despite radiological changes, which may be extensive. By definition, sarcoidosis has become chronic after 2 years of disease with ongoing signs of activity. The long-term prognosis is generally good, but depends on the different organ manifestations and complications. Georg Thieme Verlag KG Stuttgart · New York.

Common Factor Mechanisms in Clinical Practice and Their Relationship with Outcome.

PubMed

Gaitan-Sierra, Carolina; Hyland, Michael E

2015-01-01

This study investigates three common factor mechanisms that could affect outcome in clinical practice: response expectancy, the affective expectation model and motivational concordance. Clients attending a gestalt therapy clinic (30 clients), a sophrology (therapeutic technique) clinic (33 clients) and a homeopathy clinic (31 clients) completed measures of expectancy and the Positive Affect and Negative Affect Schedule (PANAS) before their first session. After 1 month, they completed PANAS and measures of intrinsic motivation, perceived effort and empowerment. Expectancy was not associated with better outcome and was no different between treatments. Although some of the 54 clients who endorsed highest expectations showed substantial improvement, others did not: 19 had no change or deteriorated in positive affect, and 18 had the same result for negative affect. Intrinsic motivation independently predicted changes in negative affect (β = -0.23). Intrinsic motivation (β = 0.24), effort (β = 0.23) and empowerment (β = 0.20) independently predicted positive affect change. Expectancy (β = -0.17) negatively affected changes in positive affect. Clients found gestalt and sophrology to be more intrinsically motivating, empowering and effortful compared with homeopathy. Greater improvement in mood was found for sophrology and gestalt than for homeopathy clients. These findings are inconsistent with response expectancy as a common factor mechanism in clinical practice. The results support motivational concordance (outcome influenced by the intrinsic enjoyment of the therapy) and the affective expectation model (high expectations can lead for some clients to worse outcome). When expectancy correlates with outcome in some other studies, this may be due to confound between expectancy and intrinsic enjoyment. Common factors play an important role in outcome. Intrinsic enjoyment of a therapeutic treatment is associated with better outcome. Active engagement with a

Purpose To investigate the clinical characteristics of X-linked retinoschisis (XLRS) and identify genetic mutations in Taiwanese patients with XLRS. Methods This study included 23 affected males from 16 families with XLRS. Fundus photography, spectral domain optical coherent tomography (SD-OCT), fundus autofluorescence (FAF), and full-field electroretinograms (ERGs) were performed. The coding regions of the RS1 gene that encodes retinoschisin were sequenced. Results The median age at diagnosis was 18 years (range 4–58 years). The best-corrected visual acuity ranged from no light perception to 20/25. The typical spoke-wheel pattern in the macula was present in 61% of the patients (14/23) while peripheral retinoschisis was present in 43% of the patients (10/23). Four eyes presented with vitreous hemorrhage, and two eyes presented with leukocoria that mimics Coats’ disease. Macular schisis was identified with SD-OCT in 82% of the eyes (31/38) while foveal atrophy was present in 18% of the eyes (7/38). Concentric area of high intensity was the most common FAF abnormality observed. Seven out of 12 patients (58%) showed electronegative ERG findings. Sequencing of the RS1 gene identified nine mutations, six of which were novel. The mutations are all located in exons 4–6, including six missense mutations, two nonsense mutations, and one deletion-caused frameshift mutation. Conclusions XLRS is a clinically heterogeneous disease with profound phenotypic inter- and intrafamiliar variability. Genetic sequencing is valuable as it allows a definite diagnosis of XLRS to be made without the classical clinical features and ERG findings. This study showed the variety of clinical features of XLRS and reported novel mutations. PMID:25999676

We set out to define the relative prevalence and common presentations of the various aetiologies of headache within an ambulant HIV-seropositive adult population in Kampala, Uganda. We conducted a prospective study of adult HIV-1-seropositive ambulatory patients consecutively presenting with new onset headaches. Patients were classified as focal-febrile, focal-afebrile, non-focal-febrile or non-focal-afebrile, depending on presence or absence of fever and localizing neurological signs. Further management followed along a pre-defined diagnostic algorithm to an endpoint of a diagnosis. We assessed outcomes during four months of follow up. One hundred and eighty patients were enrolled (72% women). Most subjects presented at WHO clinical stages III and IV of HIV disease, with a median Karnofsky performance rating of 70% (IQR 60-80).The most common diagnoses were cryptococcal meningitis (28%, n = 50) and bacterial sinusitis (31%, n = 56). Less frequent diagnoses included cerebral toxoplasmosis (4%, n = 7), and tuberculous meningitis (4%, n = 7). Thirty-two (18%) had other diagnoses (malaria, bacteraemia, etc.). No aetiology could be elucidated in 28 persons (15%). Overall mortality was 13.3% (24 of 180) after four months of follow up. Those without an established headache aetiology had good clinical outcomes, with only one death (4% mortality), and 86% were ambulatory at four months. In an African HIV-infected ambulatory population presenting with new onset headache, aetiology was found in at least 70%. Cryptococcal meningitis and sinusitis accounted for more than half of the cases.

Obstructive sleep apnea in adults: epidemiology, clinical presentation, and treatment options.

PubMed

Lurie, Alain

2011-01-01

Obstructive sleep apnea (OSA) is characterized by repetitive episodes of complete and partial obstructions of the upper airway during sleep. The diagnosis of OSA requires the objective demonstration of abnormal breathing during sleep by measuring the respiratory disturbance index (RDI, events per hour of sleep), i.e. the frequency of apnea (complete upper airway obstruction), hypopnea (partial upper airway obstruction) and arousals from sleep related to respiratory efforts. OSA is defined by combining symptoms and an RDI ≥5 or by an RDI ≥15 without symptoms. The apnea-hypopnea index (AHI), the frequency of apnea and hypopnea events per hour of sleep, is widely used to define OSA (many clinical and epidemiological studies use this metric). In the general adult population, the prevalence of OSA defined by ≥5 apnea and hypopnea events per hour of sleep associated with excessive sleepiness is approximately 3-7% in men and 2-5% in women. The prevalence of OSA is much higher, e.g. ≥50%, in patients with cardiac or metabolic disorders than in the general population. Risk factors for OSA include obesity (the strongest risk factor), upper airway abnormalities, male gender, menopause and age (the prevalence of OSA associated with a higher risk of morbidity and mortality increases with age and peaks at approximately 55 years of age). OSA is associated with symptoms during sleep (snoring, choking and nocturia) and wakefulness (excessive sleepiness, fatigue and lack of energy) and with sequelae such as psychological changes, alterations in the quality of life, and social, familial and professional performance including vehicle and industrial accidents. The identification of OSA may be a difficult task for the clinician, even in populations in which OSA is highly prevalent such as patients with cardiovascular disorders because they may not present the cardinal signs of the disease, e.g. excessive sleepiness and obesity. Guidelines have been developed to tailor OSA

The Influence of Clinical Experience and Photographic Presentation on Age Assessment of Women.

2016-01-01

Epidemiological studies have reported that a higher perceived age is associated with poor health and higher mortality. However, the method used for the assessment of perceived age differs between studies with regard to age, gender, the number and occupation of assessors as well as the presentation of participants. It is not known whether the clinical experience of the assessor or photographic presentation have an influence on the assessment of perceived age, which the present study aimed to investigate. In a cross-sectional study of 460 women aged 25-93 years, 10 consultants and 10 residents were asked to estimate the age of each participant using three different photographic presentations: facial photograph, whole-body photograph, and combined facial and whole-body photographs. Data were analyzed by means of summary statistics and linear mixed models. The inter-class correlation coefficient within each assessor group and photographic presentation varied from 0.66 to 0.75. Limits of agreement were in a broad range but were similar in the two assessor groups. The best inter-assessor agreement was obtained from photographs of both the face and the whole body. Intra- and inter-assessor agreements between photographic presentations were similar among both assessor groups. The accuracy in age assessment was significantly influenced by the photographic presentation but not by the clinical experience of the assessor. The difference in the mean perceived age of a participant of average age was estimated as +0.40 years (95% CI: -1.80; 2.59) for consultants versus residents, -2.05 years (95% CI: -2.90; -1.19) for facial photographs versus both facial and whole-body photographs, and -1.44 years (95% CI: -2.30; -0.58) for whole-body photographs versus both facial and whole-body photographs. A regression towards the mean age was seen. The assessment of perceived age was influenced by the photographic presentation but not by the clinical experience of the assessor. © 2015 S

There are limited data on whether clinical presentation at first heart failure (HF) hospitalization predicts recurrent HF events. We aimed to assess predictors of recurrent HF hospitalizations in mild HF patients with an implantable cardioverter defibrillator or cardiac resynchronization therapy with defibrillator. Data on HF hospitalizations were prospectively collected for patients enrolled in MADIT-CRT. Predictors of recurrent HF hospitalization (HF2) after the first HF hospitalization were assessed using Cox proportional hazards regression models including baseline covariates and clinical presentation or management at first HF hospitalization. There were 193 patients with first HF hospitalization, and 156 patients with recurrent HF events. Recurrent HF rate after the first HF hospitalization was 43% at 1 year, 52% at 2 years, and 55% at 2.5 years. Clinical signs and symptoms, medical treatment, or clinical management of HF at first HF admission was not predictive for HF2. Baseline covariates predicting recurrent HF hospitalization included prior HF hospitalization (HR = 1.59, 95% CI: 1.15-2.20, P = 0.005), digitalis therapy (HR = 1.58, 95% CI: 1.13-2.20, P = 0.008), and left ventricular end-diastolic volume >240 mL (HR = 1.62, 95% CI: 1.17-2.25, P = 0.004). Recurrent HF events are frequent following the first HF hospitalization in patients with implanted implantable cardioverter defibrillator or cardiac resynchronization therapy with defibrillator. Neither clinical presentation nor clinical management during first HF admission was predictive of recurrent HF. Prior HF hospitalization, digitalis therapy, and left ventricular end-diastolic volume at enrolment predicted recurrent HF hospitalization, and these covariates could be used as surrogate markers for identifying a high-risk cohort. © 2017 The Authors.

Context: Providing opportunities to develop clinical decision-making skills, including clinical reasoning, is an important aspect of clinical education. The learner-centered technique of summarizing the history and findings, narrowing the differential, analyzing the differential, probing the instructor about uncertainties, plan management, and selecting an issue for self-directed study (SNAPPS) is used in medicine to express clinical reasoning. Objective: To investigate the effects of SNAPPS on the clinical reasoning, reflection, and 4 case presentation attributes (length, conciseness, case summary, and expression of clinical reasoning) in athletic training students. Design: Randomized controlled clinical trial. Setting: Three undergraduate programs accredited by the Commission on Accreditation of Athletic Training Education. Patients or Other Participants: We randomly assigned 38 athletic training students (17 men, 21 women; age = 21.53 ± 1.18 years, grade point average = 3.25 ± 0.31) who had completed at least 1 year of clinical education and all orthopaedic evaluation coursework to the SNAPPS group or the usual and customary group using a stratification scheme. Intervention(s): The SNAPPS group completed four 45-minute clinical reasoning and case presentation learning modules led by an investigator to learn the SNAPPS technique, whereas the usual and customary group received no formal instruction. Both groups audio recorded all injury evaluations performed over a 2-week period. Main Outcome Measures: Participants completed the Diagnostic Thinking Inventory and Reflection in Learning Scale twice. Case presentations were analyzed for 4 attributes: length, conciseness, case summary, and expression of clinical reasoning. Results: Case presentations were longer (t18.806 = −5.862, P < .001) but were more concise (t32 = 11.297, P < .001) for the SNAPPS group than for the usual and customary group. The SNAPPS group performed better on both the case summary subscale

2017-11-01

Clinical Scenario: Mild traumatic brain injury, or concussion, has been associated with physical, cognitive, and emotional sequelae. Little is understood in regard to many characteristics, such as anxiety, and their effect on post-concussion symptoms. Is state anxiety, trait anxiety, or anxiety sensitivity a clinical predictor of symptoms in those presenting with mild traumatic brain injury or concussion? Summary of Key Findings: A literature search returned 3 possible studies; 3 studies met inclusion criteria and included. One study reported in athletes that greater social support was associated with decreased state-anxiety, lower state anxiety post-concussion was associated with increased social support, and that those with greater social support may experience reduced anxiety, regardless of injury type sustained. One study reported baseline trait anxiety in athletes was not significantly associated with post-concussion state anxiety, but that symptoms of depression at baseline was the strongest predictor for post-concussion state anxiety. Three studies reported that state and trait anxiety are not related to increased post-concussion symptom scores. One study reported that greater anxiety sensitivity is related to higher reported post-concussion symptom scores, which may manifest as somatic symptoms following concussion, and revealed that anxiety sensitivity may be a risk factor symptom development. Clinical Bottom Line: There is low-level to moderate evidence to support that anxiety sensitivity is linked to post-concussion symptoms. State and trait anxiety do not appear to be related to post-concussion symptoms alone. Post-concussion state anxiety may occur if post-concussion symptoms of depression are present or if baseline symptoms of depression are present. Better social support may improve state anxiety post-concussion. Strength of Recommendation: There is grade B evidence to support that state and trait anxiety are not risk factors for post

Inter-patient variability in response to opioids is well known but a comprehensive definition of its pathophysiological mechanism is still lacking and, more importantly, no studies have focused on children. The STOP Pain project aimed to evaluate the risk factors that contribute to clinical response and adverse drug reactions to opioids by means of a systematic review and a clinical investigation on paediatric oncological patients. We conducted a systematic literature search in EMBASE and PubMed up to the 24th of November 2016 following Cochrane Handbook and PRISMA guidelines. Two independent reviewers screened titles and abstracts along with full-text papers; disagreements were resolved by discussion with two other independent reviewers. We used a data extraction form to provide details of the included studies, and conducted quality assessment using the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. Young age, lung or gastrointestinal cancer, neuropathic or breakthrough pain and anxiety or sleep disturbance were associated to a worse response to opioid analgesia. No clear association was identified in literature regarding gender, ethnicity, weight, presence of metastases, biochemical or hematological factors. Studies in children were lacking. Between June 2011 and April 2014, the Italian STOP Pain project enrolled 87 paediatric cancer patients under treatment with opioids (morphine, codeine, oxycodone, fentanyl and tramadol). Future studies on cancer pain should be designed with consideration for the highlighted factors to enhance our understanding of opioid non-response and safety. Studies in children are mandatory.

Acute renal infarction (ARI) is an uncommon disease, whose real incidence is probably higher than expected. It is associated with poor prognosis in a high percentage of cases. To describe the main clinical, biochemical and radiologic features and to determine which factors are associated with poor prognosis (death or permanent renal injury). The following is a retrospective, observational, single-hospital-based study. All patients diagnosed with ARI by contrast-enhanced computed tomography (CT) over an 18-year period were included. Patients were classified according to the cardiac or non-cardiac origin of their disease. Clinical, biochemical and radiologic features were analysed, and multiple logistic regression model was used to determine factors associated with poor prognosis. A total of 62 patients were included, 30 of which had a cardiac origin. Other 32 patients with non-cardiac ARI were younger, had less comorbidity, and were less frequently treated with oral anticoagulants. CT scans estimated mean injury extension at 35%, with no differences observed between groups. A total of 38% of patients had an unfavourable outcome, and the main determinants were: Initial renal function (OR=0.949; IC 95% 0.918-0.980; p=0.002), and previous treatment with oral anticoagulants (OR=0.135; IC 95% 0.032-0.565; p=0.006). ARI is a rare pathology with non-specific symptoms, and it is not associated with cardiological disease or arrhythmias in more than half of cases. A substantial proportion of patients have unfavourable outcomes, and the initial renal function is one of the main prognostic factors. Copyright © 2015 Sociedad Española de Nefrología.

Aims To obtain information about the speciality of clinical pharmacology and therapeutics in the United Kingdom. Methods A survey of the views of 26 individuals in academic posts in clinical pharmacology and therapeutics was carried out by postal questionnaire. Response rate was 100%. Results Of 25 assessable responses of 25 centres, there were 35 academic staff of professorial status (median 2, range 0–5) and 61 staff of reader/senior lecturer status (median 2, range 0–5) but only 20 clinical staff in training grades in 19 institutions. All had extensive clinical commitments. Two-thirds of respondents considered that the speciality was stable locally and nationally. However, recruitment of trainees was poor with only 8% of responders having several good applicants for each post and 90% reported that recruitment had deteriorated in the last 5–10 years. Likely good future careers for clinical pharmacologists in training were considered by 75–80% of respondents to likely lie in the pharmaceutical industry or regulatory authorities. Greater flexibility is required to facilitate training in clinical pharmacology and therapeutics. Conclusions Clincal pharmacology and therapeutics in the United Kingdom has a strong academic base but a sub-optimal age structure. Recent experience in recruitment into training posts was disappointing. This may reflect wider problems of recruitment into academic medicine in this country. PMID:9241105

To explore the clinical characteristics and prognostic factors of pulmonary tuberculosis with concurrent lung cancer. Comprehensive analyses were conducted for 58 cases of pulmonary tuberculosis patients with lung cancer. Their clinical symptoms, signs and imaging results were analyzed between January 1998 and January 2005 at Qingdao Chest Hospital. Kaplan-Meier method was utilized to calculate their survival rates. Nine prognostic characteristics were analyzed. Single factor analysis was performed with Logrank test and multi-factor analysis with Cox regression model. The initial symptoms were cough, chest tightness, fever and hemoptysis. Chest radiology showed the coexistence of two diseases was 36 in the same lobe and 22 in different lobes. And there were pulmonary nodules (n = 24), cavities (n = 19), infiltration (n = 8) and atelectasis (n = 7). According to the pathological characteristics, there were squamous carcinoma (n = 33), adenocarcinoma (n = 17), small cell carcinoma (n = 4) and unidentified (n = 4) respectively. The TNM stages were I (n = 13), II(n = 22), III (n = 16) and IV (n = 7) respectively. The median survival period was 24 months. And the 1, 3, 5-year survival rates were 65.5%, 65.5% and 29.0% respectively. Single factor analysis showed that lung cancer TNM staging (P = 0.000) and tuberculosis activity (P = 0.024) were significantly associated with patient prognosis. And multi-factor analysis showed that lung cancer TNM staging (RR = 2.629, 95%CI: 1.759-3.928, P = 0.000) and tuberculosis activity (RR = 1.885, 95%CI: 1.023-3.471, P = 0.042) were relatively independent prognostic factors. The clinical and radiological characteristics contribute jointly to early diagnosis and therapy of tuberculosis with concurrent lung cancer. And TNM staging of lung cancer and activity of tuberculosis are major prognostic factors.

The incidence of gram-negative multi-drug-resistant (MDR) infections is increasing worldwide. This study sought to determine the incidence, clinical profiles, risk factors, and mortality of these infections in general surgery patients. All general surgery patients with a clinical infection by gram-negative MDR bacteria were studied prospectively for a period of five years (2007-2011). Clinical, surgical, and microbiologic parameters were recorded, with a focus on the identification of risk factors for MDR infection and mortality. Incidence of MDR infections increased (5.6% to 15.2%) during the study period; 106 patients were included, 69.8% presented nosocomial infections. Mean age was 65 ± 15 years, 61% male. Extended-spectrum β-lactamases (ESBL) Escherichia coli was the most frequent MDR bacteria. Surgical site infections and abscesses were the most common culture locations. The patients presented multiple pre-admission risk factors and invasive measures during hospitalization. Mortality was 15%, and related to older age (odds ratio [OR] 1.07), malnutrition (OR 13.5), chronic digestive conditions (OR 4.7), chronic obstructive pulmonary disease (OR 3.9), and surgical re-intervention (OR 9.2). Multi-drug resistant infections in the surgical population are increasing. The most common clinical profile is a 65-year-old male, with previous comorbidities, who has undergone a surgical intervention, intensive care unit (ICU) admission, and invasive procedures and who has acquired the MDR infection in the nosocomial setting.

To define the incidence, clinical presentation, radiologic findings and principles of diagnosis, and management of acute graft pancreatitis occurring more than 3 months after transplantation. Acute graft pancreatitis is a frequent late complication after simultaneous pancreas-kidney transplantation (SPKT) with enteric drainage that is not well understood. We performed a retrospective analysis of data from patients who underwent SPKT with enteric drainage at our institution. All recipients who experienced episodes that met the clinical criteria for late graft pancreatitis were included. We excluded events proven to be anastomotic or duodenal stump leaks. Clinical presentation, laboratory findings, radiologic imaging, course of management, and graft and patient outcome were evaluated and analyzed. Of 79 SPKTs (1995-2007), 11 (14%) recipients experienced 31 episodes of late graft pancreatitis (average number per patient, 3; range, 1-13), occurring an average of 28 months after transplantation (range, 3 months to 8 years). All patients presented with right lower quadrant abdominal peritonitis, fever, and findings compatible with pancreas graft inflammation on computed tomography or ultrasound imaging. Mild hyperamylasemia (>110 IU/L) was found in 82% of cases. Treatment was conservative, including bowel rest, antibiotics, and percutaneous sampling and drainage of abscesses as necessary. Excellent graft and patient survival were achieved. The diagnosis of late acute graft pancreatitis is clinical, with confirmatory computed tomography or ultrasound imaging. Conservative treatment yields excellent graft and patient survival.

While a clinical pre-selection screening process for a stroke patient's suitability for driving has been acknowledged, little is known about the factors or processes influencing this screening typically conducted by clinicians practicing at a generalist level. This study explored this clinical stratification process through the use of semi-structured interviews with senior occupational therapists (n = 17) and stroke physicians (n = 7) using qualitative description methodology. The findings revealed a trichotomy stratification of stroke patients for driving in the clinical setting; those who are fit to drive, unfit to drive, and a "maybe" group who need more detailed assessment and observation. Factors that had a major influence on this clinical-based stratification of driving suitability were client's levels of awareness, insight, and impulsivity. A period of prolonged contact with the client was preferential to guide the stratification decision in order for clinicians to build a comprehensive picture of the person. A mix of assessment approaches including standardized assessment but with increased emphasis on naturalistic observation of functional performance underpinned the clinical stratification process. This study uncovers some of the factors and processes influencing the early clinical-based stratification of driving suitability after stroke, and highlights the contribution of the generalist practitioner in the assessment of fitness to drive continuum.

Small fibre neuropathies are a heterogeneous group of disorders affecting thinly myelinated Aδ-fibres and unmyelinated C-fibres. Although multiple causes of small nerve fibre degeneration have been reported, including via genetic mutations, the cause of small fibre neuropathy remains unknown in up to 50% of cases. The typical clinical presentation of small fibre neuropathy is that of a symmetrical, length-dependent polyneuropathy associated with sensory or autonomic symptoms. More rarely, the clinical presentation is characterised by non-length-dependent, focal, or multifocal symptoms. The diagnostic tests to identify small fibre neuropathy include skin biopsy, quantitative sensory, and autonomic testing. Additional tests, such as those measuring small fibre-related evoked potentials and corneal confocal microscopy, might contribute to a better understanding of these neuropathies. Biochemical markers can also help in screening patients for the presence of small fibre neuropathy and to assess disease progression. Copyright © 2017 Elsevier Ltd. All rights reserved.

The aim of the study was to describe the relation between sensory issues and medical complexity in a series of patients presenting to an outpatient multidisciplinary feeding team for evaluation, by a standardized measure of sensory-processing abilities. A retrospective chart review of all of the patients seen from 2004 to 2009 on 2 key variables: medical diagnostic category and short sensory profile (SSP) score. On the SSP, 67.6% of children scored in the clinical ("definite difference") range. The most common diagnostic categories were developmental (n = 23), gastrointestinal (n = 16), and neurological (n = 13). Behavioral and cardiorespiratory medical diagnostic categories were significantly related to SSP total score and SSP definite difference score. Children who present for feeding evaluation do indeed tend to have clinically elevated scores regarding sensory processing, and these elevated scores are significantly related to certain medical diagnostic categories. Future research is needed to determine why these significant relations exist as well as their implications for treatment of feeding-related issues.

The objective of the study was to investigate initial clinical characteristics that can suggest an early diagnosis of patients with acute renal infarction presenting with flank and/or abdominal pain in the emergency department (ED). From January 1, 1996, through December 31, 2005, 20 adult patients with renal infarction diagnosed by contrast-enhanced computed tomography in the ED were enrolled. Medical records, including demographic data, risk factors for thromboembolism, initial clinical presentations, laboratory data, treatment programs and outcomes, were retrospectively reviewed and analyzed. Mean patient age was 60.3 years (range, 21-80). The estimated incidence of renal infarction was 0.004% (20 of 481,540) among the ED census. The median time of onset of symptoms before the ED visit was 31 hours (range, 1-285). Eighteen patients (90%) had a history of more than 1 risk factor for thromboembolic events. In clinical presentations, all the patients had either abdominal or flank pain and tenderness. Nineteen patients (95%) had an elevated serum lactate dehydrogenase level with a mean +/- SD of 812.1 +/- 569.4 U/L. Sixteen patients (80%) presented with the triad--persisting flank or abdominal pain/tenderness, elevated serum lactate dehydrogenase level, and proteinuria. Among all 20 patients, 10 patients (50%) were diagnosed as having renal infarction at the initial ED visit. No specific clinical characteristics could be identified to distinguish those patients diagnosed early and those with delayed diagnosis. All 20 patients received medical treatment with coumadin, which was given in combination with heparin treatment in 11, peripheral intravenous and/or local intra-arterial thrombolytics with urokinase in 5, and mitral valve replacement in 1. No patient died. Although 4 patients had a mildly elevated serum creatinine level (>1.5 mg/dL) during hospitalization, none of them needs dialysis after more than 1 year of follow-up. In this study, we delineated

Abstract Objective To describe the characteristics of patients who presented to outpatient sport and exercise medicine clinics with concussion. Design Retrospective chart review of electronic medical records. Setting Three specialized sport and exercise medicine clinics in London, Ont. Participants A total of 283 patients presenting with concussion. Main outcome measures Data collected included demographic variables (age and sex), sport participation at the time of injury, previous medical history (including history of concussion), Post-Concussion Symptom Scale (PCSS) scores, and return-to-play (RTP) variables (delay and outcome). Results The mean age of patients presenting for care was 17.6 years; 70.9% of patients were younger than 18 years of age (considered pediatric patients); 58.8% of patients were male; and 31.7% of patients had a previous history of concussion. The main sports associated with injury were hockey (40.0%), soccer (12.6%), and football (11.7%). Return to play was granted to 50.9% of patients before the 3-week mark and 80.2% of patients before 8 weeks. Total PCSS scores (maximum score was 132) and neck scores (part of the PCSS, maximum score was 6) were significantly higher in adults compared with pediatric patients (36.2 vs 27.6, P = .02, and 1.8 vs 1.2, P = .02, respectively). A significant difference was seen in RTP, with pediatric patients returning earlier than adults did (P = .04). This difference was not seen when comparing males with females (P = .07). Longer duration of follow-up did not influence RTP outcomes. Previous history of concussion was associated with restriction from contact or collision sports (P < .001). Conclusion Given the age and sex variability found in this study, as well as in previous published reports, it is important to manage each patient individually using current best available practice strategies to optimize long-term outcomes.

The aim of this study was to investigate the risk factors affecting long-term prognosis of autotransplantation of third molars with complete root formation in males at dental clinics. Participating dentists were requested to provide information on transplantations they had undertaken from 1 January 1990 to 31 December 2010. Data on a total of 708 teeth from 637 patients were collected. After data screening and elimination, participants of this study consisted of 183 teeth of 171 males ranging from 20 to 72 years of age (mean age, 44·8 years). The cumulative survival rate was 86·0% at the 5-year mark, 59·1% at 10 years and 28·0% at 15 years. The mean survival time was 134·5 months, as calculated by the Kaplan-Meier method. Single factor analysis using the log-rank test showed that the following factors had significant influence (P < 0·05) on survival of transplanted teeth: periodontal disease as the reason for recipient site tooth extraction, fewer than 25 present teeth and Eichner index Groups B1 to C. Cox regression analysis examined five factors: age, smoking habit, recipient site extraction caused by periodontal disease, fewer than 25 present teeth and Eichner index. This analysis showed that two of these factors were significant: fewer than 25 present teeth was 2·63 (95% CI, 1·03-6·69) and recipient site extraction caused by periodontal disease was 3·80 (95% CI, 1·61-9·01). The results of this study suggest that long-term survival of transplanted teeth in males is influenced not only by oral bacterium but also by occlusal status. © 2012 Blackwell Publishing Ltd.

Predictors for return to work for those with occupational respiratory disease: clinical and structural factors.

Few occupational researchers have examined "return to work" among patients with work-related respiratory diseases. In addition, prior studies have emphasized individual patient characteristics rather than a more multi-dimensional approach that includes both clinical and structural factors. A retrospective chart review identified patients with occupational respiratory diseases in the Occupational Health Clinical Center, Syracuse, NY between 1991 and 2009. We assessed predictors of work status using an exploratory, sequential mixed methods research design, multinomial (n = 188) and Cox regressions (n = 130). The findings suggest that patients with an increased number of diagnoses, non-union members, and those who took more than a year before clinical presentation had significantly poorer work status outcomes, after adjusting for age, education level, and relevant diagnoses. Efforts to prevent slow return to work after developing occupational respiratory disease should recognize the importance of timely access to occupational health services, disease severity, union membership, and smoking status. © 2013 Wiley Periodicals, Inc.

Suicide is the leading cause of premature death in schizophrenia. Approximately 10 to 13% of deaths in schizophrenia are explained by suicide, despite widespread availability of generally effective antipsychotic treatments and suicide attempts have been reported among 20 to 50% of patients. This relatively low ratio of attempts/suicide is consistent with greater lethality of means - more violent - and intents - less ambivalence - in this population. Many studies have focused on risk factors and clinical characteristics for completed and/or attempted suicide. Commonly, sociodemographic risk factors for suicide are male sex, younger age and, among women, being unmarried, divorced or widowed. Previous suicidal behaviour is a strong risk factor for suicide and contrary to the common view, schizophrenic patients often communicate their suicidal intents shortly before death. Moreover, family history of suicide is associated with a heightened risk of suicide and is independent of the diagnosis, according to the growing literature that shows that vulnerability to suicidal behaviour is independent of psychiatric diagnosis. Suicide can occur throughout the entire course of schizophrenia. This is particularly true in those high-risk periods: early phase of the disease, active illness phase, period of relapse or during a depressive episode. The role of insight and positive symptoms remains unclear and probably needs further studies. Although not specifically for people with schizophrenia, hopelessness is a major risk factor and tragic loss is often presented as a trigger for suicide. It has been suggested that treatment side-effects, such as akathisia are associated with suicidal behaviour. A better knowledge of risk and protective factors is necessary to prevent suicide and suicidality.

The clinical value of tissue factor assays.

Tissue factor (TF) is now considered to be the primary physiologic activator of the blood coagulation system. Coupled with recent advances in our understanding of the biochemistry of TF this has heightened interest in measuring aspects of TF activity in disease states. Expression of TF by blood monocytes in various diseases is an established trigger for intravascular coagulation and there is now a considerable body of experience with its measurement. This has considerable clinical potential although more widespread application awaits a consensus on the most appropriate methodologic approach to its measurement. TF can be detected in urine and may reflect the activation state of renal macrophages. Urinary TF is increased in cancer and could have diagnostic and prognostic value in a variety of malignant diseases. Finally, it is now possible to measure soluble TF in plasma. One such assay is commercially available and is technically simple to perform. The clinical value of such assays, however, must await better understanding of the source and function of soluble TF in plasma.

The aim of this population-based study was to identify the factors associated with clinical outcomes in vemurafenib-treated patients and to evaluate outcomes across subgroups of patients with different risk profiles. Data were retrieved from the Dutch Melanoma Treatment Registry. Time to next treatment (TTNT) and overall survival (OS) of all metastatic melanoma patients who received vemurafenib between 2012 and 2015 were assessed using Kaplan-Meier estimates. A risk score was developed on the basis of all prognostic factors associated with TTNT and OS derived from multivariable Cox regression analyses. Patients were stratified according to the presence of prognostic risk factors by counting the number of factors, ranging from 0 to 6. A total of 626 patients received vemurafenib with a median follow-up of 35.8 months. The median TTNT and OS were 4.7 months [95% confidence intervals (CI): 4.4-5.1] and 7.3 months (95% CI: 6.6-8.0). The strongest prognostic factors were serum lactate dehydrogenase (LDH) level, Eastern Cooperative Oncology Group performance score, number of organ sites involved and brain metastases. Patients with a favourable risk profile (no risk factors) had a median TTNT and OS of 7.1 (95% CI: 5.8-8.5) and 15.4 months (95% CI: 10.0-20.9). The median OS more than halved for patients with greater than or equal to 2 risk factors compared with patients with no risk factors. The clinical outcomes of vemurafenib in metastatic melanoma patients with a favourable risk profile are comparable with the results of the trials. Combining prognostic factors into a risk score could be valuable to stratify patients into favourable and poor-prognosis groups.

To provide clinical outcomes of the Resonance metallic ureteral stent in patients with malignant ureteral obstruction, as well as clinical factors predicting stent failure. Cancer patients who have received Resonance stents from July 2009 to March 2012 for ureteral obstruction were included for chart review. Stent failure was detected by clinical symptoms, image studies, and renal function tests. Survival analysis for stent duration was used to estimate patency rate and factors predicting stent failure. A total of 117 stents were inserted successfully into 94 ureteral units in 79 patients. There were no major complications. These stents underwent survival analysis and proportional hazard regression. The median duration for the stents was 5.77 months. In multivariate analysis, age (P=0.043), preoperative serum creatinine level (P=0.0174), and cancer type (P=0.0494) were significant factors associated with stent failure. Cancer treatment before and after stent insertion had no effect on stent duration. Resonance stents are effective and safe in relieving malignant ureteral obstructions. Old age and high serum creatinine level are predictors for stent failure. Stents in patients with lower gastrointestinal cancers have longer functional duration.

Chest radiographs from children with community-acquired pneumonia (CAP) were categorized into three distinct presentations and each presentation was correlated to clinical and laboratory findings. Children < 59 months with CAP presenting to pediatric emergency rooms during two years were enrolled prospectively in eight centers across Europe. Clinical and laboratory data were documented and radiographs obtained from patients. Of the 1107 enrolled patients, radiographs were characterized as 74.9% alveolar CAP, 8.9% non-alveolar CAP, and 16.3% clinical CAP. Alveolar CAP patients had significantly higher rates of fever (90.7%), vomiting (27.6%), and abdominal pain (18.6%), while non-alveolar CAP patients presented more with cough (96.9%). A model using independent parameters that characterize alveolar, non-alveolar, and clinical CAP demonstrated that alveolar CAP patients were significantly older (OR = 1.02) and had significantly lower oxygen saturation than non-alveolar CAP patients (OR = 0.54). Alveolar CAP patients had significantly higher mean WBC (17,760 ± 8539.68 cells/mm 3 ) and ANC (11.5 ± 7.5 cells/mm 3 ) than patients categorized as non-alveolar CAP (WBC 15,160 ± 5996 cells/mm 3 , ANC 9.2 ± 5.1 cells/mm 3 ) and clinical CAP (WBC 13,180 ± 5892, ANC 7.3 ± 4.7). Alveolar CAP, non-alveolar CAP, and clinical CAP are distinct entities differing not only by chest radiographic appearance but also in clinical and laboratory characteristics. Alveolar CAP has unique characteristics, which suggest association with bacterial etiology. Trial number 3075 (Soroka Hospital, Israel) What is Known: • Community-acquired pneumonia in children is diagnosed based on clinical and radiological definitions. • Radiological criteria were standardized by WHO-SICR and have been utilized in vaccine studies. What is New: • Correlation between the WHO-SICR radiological definitions and clinical and laboratory parameters has not been studied

More than 161,000 lung cancer deaths are projected to occur in the U.S. in 2008. Of these, an estimated 10–15% will be caused by factors other than active smoking, corresponding to 16,000–24,000 deaths annually. Thus lung cancer in never smokers would rank among the most common causes of cancer mortality in the U.S. if considered to be a separate category. Slightly more than half of the lung cancers caused by factors other than active smoking occur in never smokers. As summarized in the accompanying article, lung cancers that occur in never smokers differ from those that occur in smokers in their molecular profile and response to targeted therapy. These recent laboratory and clinical observations highlight the importance of defining the genetic and environmental factors responsible for the development of lung cancer in never-smokers. This article summarizes available data on the clinical epidemiology of lung cancer in never smokers, and the several environmental risk factors that population-based research has implicated in the etiology of these cancers. Primary factors closely tied to lung cancer in never smokers include exposure to known and suspected carcinogens including radon, second-hand tobacco smoke, and other indoor air pollutants. Several other exposures have been implicated. However, a large fraction of lung cancers occurring in never-smokers cannot be definitively associated with established environmental risk factors, highlighting the need for additional epidemiologic research in this area.

The objective of this study is to evaluate the incidence and clinical presentation of hypertensive crises in the Emergency medical services of the Community Health Centre "Dr. Mustafa Šehović" Tuzla in relation to age, sex, duration and severity of hypertension, as well as the prevalence of accompanying symptoms and clinical manifestations. The study was conducted between November 2009 and April 2010 and included 180 subjects of both sexes, aged 30-80 with a diagnosis of arterial hypertension. All subjects were divided into two groups: a control group, which consisted of subjects without hypertensive crisis (95 subjects) and an experimental group that consisted of subjects with hypertensive crisis (85 subjects). The study results indicate that female subjects were significantly over- represented compared to men (60% vs. 40 %, p=0.007). The average age of the male subjects was 55.83±11.06 years, while the female subjects' average age was 59.41±11.97 years. The incidence of hypertensive crisis was 47.22%, with hypertensive urgency significantly more represented than emergency (16.47% vs. 83.53%, p<0.0001). The majority of subjects in the experimental group (28.23%) belonged to the age group of 60-69 years of age: 26.76% urgency and 35.71% emergency. The most common accompanying symptoms in hypertensive subjects were headache (75%), chest pain (48.33%), vertigo (44.44%), shortness of breath (38.88%) and nausea (33.89%). The most common symptoms in subjects with hypertensive crisis were headache (74.11%), chest pain and shortness of breath (62.35%), vertigo (49.41%), and nausea and vomiting (41.17%). Chest pain, shortness of breath, nausea and vomiting were significantly over-represented in subjects with hypertensive crisis (p<0.005). Clinical manifestations of hypertensive emergencies in almost all subjects included acute coronary syndrome, and only one subject had acute pulmonary edema.

Some studies have shown that children and adolescents with obsessive-compulsive disorder (OCD) and co-morbid tics differ from those without co-morbid tics in terms of several demographic and clinical characteristics. However, not all studies have confirmed these differences. This study examined children and adolescents with OCD and with possible or definite tic specifiers according to the DSM-5 in order to see whether they differ from patients without any tic symptoms regarding clinical presentation and outcome of cognitive behavioral therapy (CBT). The full sample included 269 patients (aged 7-17) with primary DSM-IV OCD who had participated in the Nordic Long-term Treatment Study (NordLOTS). Symptoms of tics were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia (K-SADS-PL). One or more tic symptoms were found in 29.9% of participants. Those with OCD and co-morbid tic symptoms were more likely male, more likely to have onset of OCD at an earlier age, and differed in terms of OCD symptom presentation. More specifically, such participants also showed more symptoms of OCD-related impairment, externalization, autism spectrum disorder (ASD), social anxiety, and attention-deficit/hyperactivity disorder (ADHD). However, the two groups showed no difference in terms of OCD severity or outcome of CBT. Children and adolescents with OCD and co-morbid tic symptoms differ from those without tic symptoms in several aspects of clinical presentation, but not in their response to CBT. Our results underscore the effectiveness of CBT for tic-related OCD. Nordic Long-term Obsessive-Compulsive Disorder (OCD) Treatment Study; www.controlled-trials.com ; ISRCTN66385119.

Poster presentations at major meetings serve to rapidly present and share study results with the scientific community. On the other hand, full-text publication of abstracts in peer-reviewed journals provides dissemination of knowledge. The purpose of this study was to evaluate the publication rate of abstracts presented at the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Meeting, to assess the factors influencing publication and determine the impact factor of these journals. All poster abstracts presented at the 2002 IFCC Meeting were included in the study. A Medline search was performed to identify a matching journal article. Topics, country of origin, study type, study center and publication year were tabulated. Journals and impact factors of publication were noted. Out of 900 presented abstracts, 125 (13.9%) were published as full-text articles. Publication rates according to topics of the meeting, country of origin and university affiliation demonstrated significant differences. Abstracts from multi-centered studies had higher publication rates, and the journals they were published in had higher impact factors than single center studies. The median impact factor of the journals was 2.093. According to regression analysis, the major predictors for publication were interventional research and university affiliation (odds ratios 2.916 and 1.782, respectively; p < 0.05). The publication rate for abstracts of this clinical chemistry meeting was lower than rates from other fields of medicine. Factors leading to failure require elucidation. Encouraging authors to submit their presentations for full-text publication might improve the rate of publication.

Purpose To understand the factors that facilitate career success for career development awardees in clinical and translational science and to reconceptualize understanding of career success for this population. Method In 2013–2014, the authors conducted semi-structured interviews with former NIH KL2 or K12 scholars from nine Clinical and Translational Science Award-funded institutions. Participants either had or had not secured independent funding at least two years after the end of their last K award. Questions covered the factors that facilitate or hinder junior investigators’ transition to independent funding. Interviews were recorded and transcribed and the transcripts analyzed thematically. Results Forty individuals participated, with equal representation by men and women and by independently and not independently funded investigators. Personal factors that facilitated success included: networks, persistence and resilience, initiative, autonomy, and personal and professional balance. Organizational factors included: appropriate mentorship, protected research time, and institutional resources and support. Even independently funded participants described challenges regarding career direction. Five participants without independent funding modeled a broad spectrum of successful career paths, having assumed leadership positions not reliant on grant funding. Alternative definitions of career success included: improving public health, enjoying work, seeing mentees succeed, and receiving external acknowledgement of successes. Conclusions Awareness of the factors that facilitate or hinder career success can help junior faculty, mentors, and institutional leaders support career development in clinical and translational science. New definitions of career success are needed, as are career paths for faculty who want to engage in research in roles other than principal investigator. PMID:26509600

The nonspecific clinical presentation of pulmonary embolism (PE) frequently leads to delay in its diagnosis. This study aimed to assess the impact of delay in presentation on the diagnostic management and clinical outcome of patients with suspected PE. In 4,044 consecutive patients with suspected PE, patients presenting more than 7 days from the onset of symptoms were contrasted with those presenting within 7 days as regards the safety of excluding PE on the basis of a clinical decision rule combined with D-dimer testing. Patients were followed for 3 months to assess the rates of recurrent venous thromboembolism and mortality. A delayed presentation (presentation >7 d) was present in 754 (18.6%) of the patients. The failure rate of an unlikely clinical probability and normal D-dimer test was 0.5% (95% confidence interval [CI], 0.01-2.7) for patients with and 0.5% (95% CI, 0.2-1.2) for those without diagnostic delay. D-dimer testing yielded a sensitivity of 99% (95% CI, 96-99%) and 98% (95% CI, 97-99%) in these groups, respectively. Patients with PE with diagnostic delay more frequently had centrally located PE (41% vs. 26%; P < 0.001). The cumulative rates of recurrent venous thromboembolism (4.6% vs. 2.7%; P = 0.14) and mortality (7.6% vs. 6.6%; P = 0.31) were not different for patients with and without delayed presentation. PE can be safely excluded based on a clinical decision rule and D-dimer testing in patients with a delayed clinical presentation. A delayed presentation for patients who survived acute PE was associated with a more central PE location, although this did not affect the clinical outcome at 3 months.

This retrospective chart review evaluated a comparison of the clinical profiles of older outpatients having mania and those with unipolar depression. The charts of elderly outpatients with mania and unipolar depression in tertiary care settings were reviewed and relevant information incorporated regarding clinical presentation, past and family history of affective disorder, treatment history and previous psychiatric and neurological history. Charts for 30 patients with mania (23 men and 7 women with mean (+/-SD) age of 68.5(+/- 5.75 years) and 92 with depression (47 men and 45 women with mean (+/-SD) age of 68.18 (+/-6.0 years) were evaluated. Fifteen patients (50%) with manic episodes had psychotic symptoms in the form of delusions and hallucinations while only 33 (35.8%) depressed patients had psychotic symptoms. One-third of manic patients received mood stabilizers at index visit. More than half (n = 16; 53.3%) of the patients in the mania group were prescribed antipsychotic medications. On cognitive functions, patients with manic episodes scored poorly compared with those with depression. These findings suggest that mania in the elderly is a severe form of affective disorder with respect to psychotic and cognitive symptoms. Conclusions from this study are limited due to its retrospective design. Further studies in this area are warranted.

Objective There is a paucity of research on patients presenting with uninfected diabetic foot ulcers (DFU) that go on to develop infection. We aimed to investigate the incidence and risk factors for developing infection in a large regional cohort of patients presenting with uninfected DFUs. Methods We performed a secondary analysis of data collected from a validated prospective state-wide clinical diabetic foot database in Queensland (Australia). Patients presenting for their first visit with an uninfected DFU to a Diabetic Foot Service in one of thirteen Queensland regions between January 2012 and December 2013 were included. Socio-demographic, medical history, foot disease history, DFU characteristics and treatment variables were captured at the first visit. Patients were followed until their DFU healed, or if their DFU did not heal for 12-months, to determine if they developed a foot infection in that period. Results Overall, 853 patients were included; mean(standard deviation) age 62.9(12.8) years, 68.0% male, 90.9% type 2 diabetes, 13.6% indigenous Australians. Foot infection developed in 342 patients for an overall incidence of 40.1%; 32.4% incidence in DFUs healed <3 months, 55.9% in DFUs healed between 3–12 months (p<0.05). Independent risk factors (Odds Ratio (95% confidence interval)) for developing infection were: DFUs healed between 3–12 months (2.3 (1.6–3.3)), deep DFUs (2.2 (1.2–3.9)), peripheral neuropathy (1.8 (1.1–2.9)), previous DFU history (1.7 (1.2–2.4)), foot deformity (1.4 (1.0–2.0)), female gender (1.5 (1.1–2.1)) and years of age (0.98 (0.97–0.99)) (all p<0.05). Conclusions A considerable proportion of patients presenting with an uninfected DFU will develop an infection prior to healing. To prevent infection clinicians treating patients with uninfected DFUs should be particularly vigilant with those presenting with deep DFUs, previous DFU history, peripheral neuropathy, foot deformity, younger age, female gender and DFUs

There is evidence for a direct role of quantitative gene expression deregulation in mantle-cell lymphoma (MCL) pathogenesis. Our aim was to investigate gene expression associations with other pathogenic factors and the significance of gene expression in a multivariate survival analysis. Quantitative expression of 20 genes of potential relevance for MCL prognosis and pathogenesis were analyzed using real-time reverse transcriptase polymerase chain reaction and correlated with clinical and genetic factors, tumor morphology, and Ki-67 index in 65 MCL samples. Genomic losses at the loci of TP53, RB1, and P16 were associated with reduced transcript levels of the respective genes, indicating a gene-dosage effect as the pathomechanism. Analysis of gene expression correlations between the candidate genes revealed a separation into two clusters, one dominated by proliferation activators, another by proliferation inhibitors and regulators of apoptosis. Whereas only weak associations were identified between gene expression and clinical parameters or blastoid morphology, several genes were correlated closely with the Ki-67 index, including the short CCND1 variant (positive correlation) and RB1, ATM, P27, and BMI (negative correlation). In multivariate survival analysis, expression levels of MYC, MDM2, EZH2, and CCND1 were the strongest prognostic factors independently of tumor proliferation and clinical factors. These results indicate a pathogenic contribution of several gene transcript levels to the biology and clinical course of MCL. Genes can be differentiated into factors contributing to proliferation deregulation, either by enhancement or loss of inhibition, and proliferation-independent factors potentially contributing to MCL pathogenesis by apoptosis impairment.

Introduction Viral warts are common skin condition caused by the human papilloma virus. Aim To determine the clinical features of warts and therapeutic approaches to warts and compare them with the literature. Material and methods A cross-sectional survey was conducted on 362 consecutive patients presenting to a dermatology clinic in Ankara, Middle Anatolia, Turkey. Age, gender, anatomic localization, clinical types, number of warts, and medical therapy histories were recorded. Results In our study 139 (38.4%) children and 223 (61.6%) adults had warts. Warts were seen in 191 men, and 171 women. The mean age was 24.7 ±13.5. In all groups the incidence and the number of warts were higher in men. Clinical types of warts were vulgar, anogenital, plantar, verruca plana, filiform, and mosaic. Thirty-six (9.9%) of 362 cases had more than one type. The locations of warts were as follows extremities (n = 233, 64.4%), anogenital (n = 86, 23.7%) and head and neck (n = 73, 20.2%). The incidence of anogenital warts was statistically higher in men than women (p < 0.05). Topical medical treatment was the first choice (n = 60, 57.1%). Conclusions In our study, the incidence and the number of warts were higher in men, which is different than in previous reports. The anogenital wart (AW) was ranked second in all types of warts. According to this finding, we can say that the frequency of AW has been increased in Turkey. To our knowledge recently there have been no studies investigating the clinical features of viral warts in all ages in the literature. PMID:26161058

The aim of this study is to prepare junior physicians, clinical education should focus on the teaching of clinical decision-making. This research is designed to explore teaching of clinical decision-making and to analyze the benefits of an "Analogy guide clinical decision-making" as a learning intervention for junior doctors. This study had a "quasi-experimental design" and was conducted in a medical center in eastern Taiwan. Participants and Program Description: Thirty junior doctors and three clinical teachers were involved in the study. The experimental group (15) received 1 h of instruction from the "Analogy guide for teaching clinical decision-making" every day for 3 months. Program Evaluation: A "Clinical decision-making self-evaluation form" was used as the assessment tool to evaluate participant learning efficiency before and after the teaching program. Semi-structured qualitative research interviews were also conducted. We found using the analogy guide for teaching clinical decision-making could help enhance junior doctors' self-confidence. Important factors influencing clinical decision-making included workload, decision-making, and past experience. Clinical teaching using the analogy guide for clinical decision-making may be a helpful tool for training and can contribute to a more comprehensive understanding of decision-making.

Impaired interpersonal, social, and occupational functioning is very often observed in patients with bipolar disorder, not only at the acute stages of the illness but in remission as well. This finding raises the question of multiple factors that might affect psychosocial functioning in bipolar patients, such as residual subsyndromal symptoms and neuropsychological deficits. Social cognition impairment, especially impaired Theory of Mind (ToM), might also play an important role in bipolar patients' every-day functioning, similarly to what was found in patients with schizophrenia. The present study aimed to investigate the potential effect of clinical and cognitive factors on the psychosocial functioning of patients with bipolar disorder during remission, assessing ToM along with a broad range of basic cognitive functions. Forty-nine patients with bipolar disorder type I in remission and 53 healthy participants were assessed in general intelligence, working memory, attention, speed processing, verbal learning and memory, and executive functions using a comprehensive battery of neuropsychological tests. The Faux Pas Recognition Test was used to assess ToM. The two groups were matched for gender, age and education level. The Hamilton Rating Scale for Depression (HDRS), the Young Mania Rating Scale (YMRS), and the Brief Psychiatric Rating Scale (BPRS) were also administered to the patients. Every-day functioning was assessed with the Global Assessment of Functioning (GAF). In order to examine the contribution of many factors in psychosocial functioning, we used hierarchical multiple regression analysis. Bipolar patients presented significant impairment compared to healthy participants in all the basic cognitive functions tested with the exception of verbal memory. Moreover, patients had significant poorer performance than healthy controls in overall psyand cognitive ToM but not in affective ToM as measured by Faux Pas. Psychosocial functioning in patient group was
