    Sports-related concussions have been shown to lead to persistent subclinical anomalies of the motor and cognitive systems in young asymptomatic athletes. In advancing age, these latent alterations correlate with detectable motor and cognitive function decline. Until now, the interacting effects of concussions and the normal ageing process on white matter tract integrity remain unknown. Here we used a tract-based spatial statistical method to uncover potential white matter tissue damage in 15 retired athletes with a history of concussions, free of comorbid medical conditions. We also investigated potential associations between white matter integrity and declines in cognitive and motor functions. Compared to an age- and education-matched control group of 15 retired athletes without concussions, former athletes with concussions exhibited widespread white matter anomalies along many major association, interhemispheric, and projection tracts. Group contrasts revealed decreases in fractional anisotropy, as well as increases in mean and radial diffusivity measures in the concussed group. These differences were primarily apparent in fronto-parietal networks as well as in the frontal aspect of the corpus callosum. The white matter anomalies uncovered in concussed athletes were significantly associated with a decline in episodic memory and lateral ventricle expansion. Finally, the expected association between frontal white matter integrity and motor learning found in former non-concussed athletes was absent in concussed participants. Together, these results show that advancing age in retired athletes presenting with a history of sports-related concussions is linked to diffuse white matter abnormalities that are consistent with the effects of traumatic axonal injury and exacerbated demyelination. These changes in white matter integrity might explain the cognitive and motor function declines documented in this population.

    In front of a patient with arthritis, clinical good-sense tells that the most probable diagnosis are the most prevalent ones. Nevertheless, we have to exclude a multiplicity of other aetiologies, less frequent, but with highest implications in the therapeutic conduct. Infections by Brucella and by Borrelia are rare causes of chronic arthritis, yet are diagnosis to consider, even when the clinical manifestations aren't the most typical, as there still exist endemic areas in Portugal. Here we report two clinical cases about patients with arthritis for more than one year, subject to ineffective exams ant treatments. Only the clinical history could put on evidence clinical-epidemiological data, suggestive of Brucellosis and Lyme Disease, namely the professional contact with infected animals, and the history of probable erythema migrans, that pointed toward the correct diagnosis. So, with directed therapeutic, there was complete resolution of the inflammatory symptoms.

  5. [The concept of tic in the history of abnormal movements].

    History of abnormal movements started during the 14th century. At that time the St Vitus' Dance was described, but the nosology of dyskinesias remained confusing during the next five centuries. The concept of tic was elaborated in France during the 18th century. It remained too large a concept however. Definitive semiologies appeared at the end of the 19th century, thus allowing tics to emerge from the "chaos of choreas". The etymology of the word "tic" still remains mysterious. In 1905, Meige thought that the word tic was used for the first time by reference to horses. He referred to the tic of the bear in the horse described by Rudler and Chomel at The Société de Neurologie de Paris in 1903. Veterinarians were thus probably the first to describe the word. If so, however, the horse must leave anteriority to the goat. The word Ticq was used in 1611 as mentioned by the French dictionary Robert. The word is said to be an onomatopea and is compared to the italian word ticchio which means caprice. Another dictionary (Littré) suggest the german word "ticken", which means "to touch slightly", the galic word tacaid (sudden pain) and the german ziki (young goat), a word which could have lead to ticchio as capra, goat in italian, gave capricio.

    Full Text Available Background: Indication of a head computed tomography (CT scan in a patient who remains conscious after head injury is controversial. We aimed to determine the clinical features that are most likely to be associated with abnormal CT scan in patients with a history of head injury, and who are conscious at the time of presentation to casualty. Materials and Methods: This is a prospective observation study of patients presented to casualty with history of head injury, and who were conscious, i.e., Glasgow Coma Scale (GCS 15 at the time of evaluation. All patients underwent head CT scan. The CT scan was reported as abnormal if it showed any pathology ascribed to trauma. The following variables were used: age, gender, mode of injury (road traffic accident, fall, assault, and others, duration since injury, and history of transient loss of consciousness, headache, vomiting, ear/nose bleeding, and seizures. Logistic regression analysis was used to identify the clinical features that predicted an abnormal CT scan. Results: During the observation period, a total of 1629 patients with head injury were evaluated, out of which 453 were in GCS 15. Abnormal CT scan was present in 195 (43% patients. Among all the variables, the following were found significantly associated with abnormal CT scan: duration since injury (>12 h P< 0.001; vomiting odds, ratio (OR 1.89 (1.23, 2.80, P< 0.001; and presence of any symptom, OR 2.36 (1.52, 3.71, P< 0.001. Conclusion: A patient with GCS 15 presenting after 12 hours of injury with vomiting or combination of symptoms has a significant risk of abnormal head CT scan.

    2012-01-01

    Full Text Available Background: The differences in digit ratio are proposed to arise due to differential effects of sex steroids on the growth of finger bones. In this study, we sought to examine the sex differences and the influence of family history of psychosis on digit ratio in patients with schizophrenia compared to matched healthy controls (HCs. Materials and Methods: Digit ratio (2D: 4D was examined for a large sample of schizophrenia patients (n=200 and HC (n=177 to evaluate the potential effects of family history. Results: The right hand 2D: 4D digit ratio was lesser in schizophrenia patients compared to HC (0.97±0.05 vs 0.98±0.04, t=2.2, P=0.02. There was a significant difference in the right hand 2D: 4D digit ratio of female patients with schizophrenia when compared to female HCs (0.96±0.05 vs 0.98±0.03, t=2.1, P=0.03 while males showed no such difference on either hands. On the contrary, family history‑positive males showed a significantly greater digit ratio for the left hand (FH present (0.99±0.04 vs HC (0.97±0.04, t=2.15, P=0.03, while there was no difference between family history‑positive females and HC. Conclusion: Overall, in patients, reversal of expected "directionality" in digit ratio was observed in our study with greater left 2D: 4D in male patients having a family history of schizophrenia being a novel finding. Reversal of sexual dimorphism has been linked to the pathogenesis of schizophrenia. It is possible that such reversal might have a putative genetic basis, perhaps only in men with schizophrenia.

  10. Fixed and dilated: the history of a classic pupil abnormality.

    Koehler, Peter J; Wijdicks, Eelco F M

    2015-02-01

    The aim of this study was to investigate the development of ideas about the nature and mechanism of the fixed dilated pupil, paying particular attention to experimental conditions and clinical observations in the 19th century. Starting from Kocher's standard review in 1901, the authors studied German, English, and French texts for historical information. Medical and neurological textbooks from the 19th and 20th centuries were reviewed to investigate when and how this information percolated through neurological and neurosurgical practices. Cooper experimented with intracranial pressure (ICP) in a dog in the 1830s, but did not mention the pupils. He described dilated pupils in clinical cases without referring to the effect of light. Bright demonstrated to have some knowledge of the pupil sign (clinical observations). Realizing the unreliability of the pupil sign, Hutchinson in 1867-1868 tried to reason in which cases trepanation would be advisable. Von Leyden's 1866 animal experiments, in which he increased CSF volume by injecting protein solutions intracranially, was the first observation in which the association between fixed dilated pupils and increased ICP was established. Along with bradycardia and motor and respiratory effects, he noticed wide pupils were usually present in a comatose state. Asymmetrical dilation could not always be attributed to increased ICP, but to an oculomotor nerve lesion. Pagenstecher in 1871 extended knowledge by meticulously studying consecutive pupil phenomena with increasing pressure. In 1880, von Bergmann emphasized the significance of the ipsilateral dilation in experiments as well as in clinical cases. He distinguished the extent of pressure increase and its duration. Probably confusing irritation (epileptic head turning to the other side with pupil dilation) and lesion effects, he suggested a cortical area responsible for oculomotor phenomena, indicating what is now known as the frontal eye field.

    The purpose of the Symposium on Clinical Pharmacy and Clinical Pharmacology is to describe the present and future functional roles of clinical pharmacists and clinical pharmacologists in drug research, professional education, and patient care. Clinical pharmacy is a relatively new professional discipline, being only about 15 years old. This new breed of pharmacists is patient rather than drug product oriented. The discipline arose out of dissatisfaction with old practice norms and the pressing need for a health professional with a comprehensive knowledge of the therapeutic use of drugs. The clinical pharmacy movement began at the University of Michigan in the early 1960s, but much of the pioneering work was done by David Burkholder, Paul Parker, and Charles Walton at the University of Kentucky in the latter part of the 1960s. Clinical pharmacology is a professional discipline that combines basic pharmacology and clinical medicine. Its development began in the early 1950s, primarily as a result of the efforts of Harry Gold. It has had a slower growth than clinical pharmacy but it has made many important contributions to our knowledge of human pharmacology and the rational use of drugs.

    In this paper, I review the origins of Clinical Enzymology with special emphasis on the years between 1960 and 1980 when the greatest advances in the subject took place. These are described in relation to my own research interests and contributions, focusing upon subclinical hepatic damage caused by viral infection and by alcohol; myocardial infarction; detection of cervical carcinoma by vaginal fluid analysis; evaluation of pancreatic function; and the clinical implications of microsomal enzyme induction. Reasons are proposed for the failure of enzymology to attain the status of an autonomous medical specialty, in contrast to the success of similar fields of knowledge that grew up in the same era.

    2016-09-01

    Full Text Available Aim: To evaluate the clinical manifestations of abnormal uterine bleeding (AUB, ultrasonography findings and compare with histopathological results.Material and Method: A total of 404 women with AUB were classified as; Group I: 18-39 years, Group II: 40-50 years, Group III: >50 years old. Age, parity, bleeding pattern, menstrual history, laboratory results, ultrasonography and histopathological findings were evaluated. Results: Almost half presented with AUB were in the premenopausal group [196 (48.51%], followed by 150(37.13% postmenopausal group and 58(14.36% reproductive age group. The most common bleeding pattern was menometrorrhagia followed by metrorrhagia. Endometrial pathologies were observed in 306 (75.74% and normal menstrual pattern in 98 (24.26% participants of AUB. Endometrium cancer was seen in 7 (1.7% women. In the reproductive period most common pathology was hormonal imbalance pattern. Endometrial polyp was the dominant pathology in premenopausal and postmenopausal age groups. All malignancy cases were in the postmenopausal age group. Malignancy was in 4(19.04% women who gave birth < 3 and in 1(4.76% who had %u22653 children. Four women with vaginal delivery had malignancy whereas no malignancy was seen in women with only cesarean history. Among 109 women who had endometrial thickness 4mm, 30 (10.17% had endometrial hyperplasia, 6(2.03% had endometrium cancer. Discussion: Transvaginal ultrasonography can be used as diagnostic method to evaluate endometrial thickness and differentiate uterine pathologies. However in the case of recurrent uterine bleeding, endometrial sampling should be performed disregarding ultrasonography findings.

    Objective: To study the value of detecting fetal congenital heart disease (CHD) using the five transverse planes technique of fetal echocardiography. Methods: Nine hundred and eighty-two high-risk pregnancies for fetal CHD were included in this study, the fetal heart was scanned with the five transverse planes technique of fetal echocardiography described by yagel, autopsy was conducted when pregnancy was terminated. Blood from fetal heart was collected for fetal chromosome analysis. A close follow-up was given for normal fetal heart pregnancies and neconatal echocardiography was performed to check the accuracy of prenatal diagnosis. Results: (1) Forty-six cases(4.68%) were found to have fetal heart abnormalities in this study, 69.56% of them were diagnosed by single four-chamber view, another 30.43% fetal CHD were found by combining other views; (2) Fotry-one parents of prenatal fetuses with CHD chose to terminate pregnancy, thirty-two of them gave consent to conduct autopsy, 93.75% of which yielded unanimous conclusion between prenatal fetal echocardiography and autopsy; (3) Thirty-two of 46 cases underwent fetal chromosome analysis, 8 cases (25%) were found to have abnormal chromosome; (4) Five cases were found to have right ventricle and atrium a little bigger than those on the left side, with the unequal condition being the same after birth, but there were no clinical manifestations and they are healthy for the time being; (5) Nine hundred and thirty-six cases were not found with abnormality in this study, but one case was diagnosed with ventricular septal defect after birth, one case was diagnosed with patent ductus arteriosus, one case had atrial septal defect after birth. Conclusions: (1) The detected CHD rate was 4.68% by screening fetal heart with five transverse planes according to Yagel's description of high risk population basis for CHD. The coinciding rate of prenatal diagnosis and autopsy was 93.75%; (2) The sensitivity of detecting fetal heart

    Congenital middle ear malformations are rare. Most part of them are usually associated with other malformations, such as aural atresia, microtia, and dysmorphic craniofacial features. A clinical case of a 24-year-old male with a right-sided conductive hearing loss since his childhood, without craniofacial malformation, is presented. He was proposed for exploratory tympanotomy under the suspicious diagnosis of otosclerosis. The surgery revealed an abnormal location of stapes' superstructure, which was attached to the promontory and had an isolated and mobile osseous footplate in the oval window. A stapes prosthesis was inserted and resulted in closure of the air-bone gap by 25 dB. A review of the literature was also performed using MEDLINE. Two theories diverge on the embryologic origin of the stapes. Our findings seem to be in favour of the theory that defines two different embryologic origins to the stapes. PMID:27648330

    Hemifacial spasm (HFS) is defined as an involuntary, irregular clonic, or tonic movement of muscles innervated by the ipsilateral seventh cranial nerve. It is reported that the coexistence of non-motor- and motor-related symptoms can be seen in patients with HFS. Postural disturbances were investigated in some movement disorders; however, postural abnormalities due to HFS had not been reported before. In this study, we aimed to investigate the postural abnormalities in patients with HFS. In this cross-sectional, controlled study, Tinetti Balance and Gait Test (TBGT) scores and static posturography were performed on fifteen patients with HFS and fifteen healthy age- and sex-matched controls. The total TBGT score and TBGT-balance score were found to be significantly lower in the patient group than in the control group (p values were, respectively, 0.046 and 0.011). The ratio of the patients with high risk of falling was 40 %, and the difference was found to be significantly higher in the patient group (p value = 0.008). In Fourier analyses, a significant difference was found in the medium to high frequencies (F5-6) when the posturographic evaluation was performed on a solid ground with closed eyes, head rotated to right, and head rotated to the left positions (p values were, respectively, 0.045 and 0.007). The stability index of the HFS group was significantly higher than the control group when tested on the neutral, head right, and head left positions (p values were, respectively, 0.004, 0.049, and 0.003). In conclusion, our study showed that the patients with HFS have more balance and falling problems than the controls, which can be both clinically and posturographically determined.

    Recently, we evaluated three sibs with Carpenter syndrome, permitting further clinical, orthopedic, radiographic, and psychometric delineation of this disorder. All three patients were operated on for craniostenosis at or before 2 months. Although all had gross motor delay in early infancy, two had normal intelligence at 12 months and 10 years, respectively. Bony abnormalities contributed to functional impairment especially in the older children. Preaxial polydactyly of feet was present in all three affected sibs and in all other reported individuals with this condition, allowing differentiation of Carpenter syndrome from the other autosomal-recessive acrocephalopolysyndactyly syndromes.

    Vascular and baroreceptor abnormalities in 44 young males, mean age 21 years, comprising of offspring with (FH(+); n = 22) and without (FH(-); n = 22) hypertensive parents, were investigated. Peak forearm blood flow (FBF), which was defined as the highest blood flow obtained following reactive hyperaemia, was assessed using strain gauge plethysmography following 5 min of ischemia. Cardiopulmonary baroreceptor sensitivity was assessed using lower body negative pressure for 5 min at -20 mmHg and was determined by calculating change of stroke volume and forearm vascular resistance (FVR) to lower body negative pressure. Carotid baroreceptor sensitivity was assessed using neck suction at -20, -40, -60, and -80 mmHg and was calculated by dividing RR interval by systolic blood pressure. Augmentation index, a measure of wave reflection, was assessed using applanation tonometry and was calculated as the ratio of augmented pressure and pulse pressure. Peak FBF of FH(+) was 19% lower than the FH(-) (p = 0.02). Also FH(+) had 17% higher peak FVR compared to FH(-) (p = 0.04). However, there were no significant differences between groups for cardiopulmonary, carotid baroreceptor sensitivity, and augmentation index. These results suggest that peripheral vascular dysfunction appears earlier than abnormal baroreceptor sensitivity in young males with a family history of hypertension.

    Array comparative genomic hybridization (aCGH) testing can diagnose chromosomal microdeletions and duplications too small to be detected by conventional cytogenetic techniques. We need to consider which patients are more likely to receive a diagnosis from aCGH testing versus patients that have lower likelihood and may benefit from broader genome wide scanning. We retrospectively reviewed charts of a population of 200 patients, 117 boys and 83 girls, who underwent aCGH testing in Genetics Clinic at Rhode Island hospital between 1 January/2008 and 31 December 2010. Data collected included sex, age at initial clinical presentation, aCGH result, history of seizures, autism, dysmorphic features, global developmental delay/intellectual disability, hypotonia and failure to thrive. aCGH analysis revealed abnormal results in 34 (17%) and variants of unknown significance in 24 (12%). Patients with three or more clinical diagnoses had a 25.0% incidence of abnormal aCGH findings, while patients with two or fewer clinical diagnoses had a 12.5% incidence of abnormal aCGH findings. Currently, we provide families with a range of 10-30% of a diagnosis with aCGH testing. With increased clinical complexity, patients have an increased probability of having an abnormal aCGH result. With this, we can provide individualized risk estimates for each patient.

    Myeloid neoplasms with eosinophilia and abnormalities of PDGFRB gene are a new kind of myeloid disorders in the revised 2008 WHO classification. Out of detected 2000 cases of myeloid cell abnormalities in our hospital, 12 cases of myeloid neoplasms with eosinophilia and abnormalities of PDGFRB were found. This study was purposed to summarize and analyze the clinical and laboratorial characteristics of the 12 cases with PDGFRB gene abnormalities. The results indicated that among 12 cases of myeloid neoplasms with PDGFRB abnormalities, 5 cases with TEL/PDGFRB fusion gene, 2 cases with HEPI/PDGFRB, 1 case with PDGFRB mutation, 1 case with RABAPTIN-5/PDGFRB, 1 case with GIT2/PDGFRB, 1 case with TP53/PDGFRB, 1 case with WDR43/PDGFRB fusion gene were detected, showing the polymorphism of PDGFRB gene abnormalities. Among this kind of myeloid neoplasm patients, almost all patients manifested monocytosis and eosinophilia in different degree, the thrombocytosis mainly was observed in atypical myeloid neoplasms, acute leukemia, chromic myelo-monocytic leukemia patients. The treatment with imatinib mesylate for this kind of patients was effective in some cases. It is concluded that the myeloid neoplasms with PDGFRB gene abnormalities are a kind of heterogenetic myeloid neoplasms, their gene abnormal types and clinical manifestations show polymorphism too. The monocytosis and eosinophilia appear in this kind myeloid neoplasms which may be treated with tyrosine kinase inhibitors such as imatinib mesylate.

    Full Text Available INTRODUCTION: This article deals with the description and diagnosis of a new nosographic syndrome, which received the eponym of "Cugini's syndrome" by the name of the Author who discovered its clinical picture. This syndrome is characterized by the binomial: "minimal target organ damage associated to monitoring prehypertension". CLINICAL HISTORY AND DIAGNOSIS: Between the years 1997 and 2002, the Author published a series of investigations regarding some office normotensives who inexplicably showed incipient signs of target organ damage (TOD. Investigated via ambulatory (A blood (B pressure (P monitoring (M, these subjects were surprisingly found not to be hypertensive. Neverthless, the office normotensives with TOD exibited the daily mean level of their systolic (S and diastolic (D BP (DML SBP/DBP significantly more elevated as compared to true normotensives. Because of these ABPM findings, the Author realized that the investigated subjects were false normotensives whose TOD was associated with a monitoring prehypertension (ABPM-diagnosable prehypertension alias monitoring prehypertension alias masked prehypertension. The year after the last Cugini's investigation, the INC-7 Reports introduced the term: "prehypertension" in its classification of arterial hypertension, as an office sphygmomanometric condition in between office normotension and office hypertension. The ABPM cut-off upper limits for a differential diagnosis between monitoring normotension, prehypertension and hypertension are reported, as calculated by the Author in its collection of ABPMs. The eponym of "Cugini's syndrome" was assigned in 2007 and confirmed in 2009. CONCLUSIVE REMARKS: The monitoring prehypertension is a further condition of discrepancy between office sphygmomanometry and ABPM, as per a masked prehypertension, whose diagnosis has to be immediately diagnosed, for preventing the onset of a TOD. There are reported the present investigations dealing with the possible

    Tomoko Oeda

    Full Text Available BACKGROUND: Abnormal posture (AP is often seen in Parkinson's disease (PD, and marked forms known as dropped head syndrome and camptocormia encumber daily living activities. Unlike other motor disabilities such as bradykinesia or muscular rigidity, AP is not always improved but rather deteriorated by PD medication. PURPOSE: To clarify factors associated with neck and thoracolumbar AP. METHODS: Neck flexion (NF and thoracolumbar (TL angles were measured in 216 consecutive PD patients and 175 elderly healthy controls. The differences in NF and TL angles between PD patients and controls were designated as ΔNFA and ΔTLA, respectively. The association of ΔNFA or ΔTLA and predictable factors such as age, sex, duration of PD, Hoehn Yahr (H-Y stage, Unified Parkinson's Disease Rating Scale Part 3 (UPDRS-3, daily dose of dopamine agonists, and comorbid orthopedic spinal lesions was investigated in PD patients. Patients were divided into quartiles according to ΔNFA or ΔTLA. The association between predictable factors and ΔNFA or ΔTLA was estimated as odds ratio (OR, comparing with the lowest quartile as the reference by multivariate regression analysis. RESULTS: Compared with controls, distributions of all three posture angles were significantly shifted rightward in PD patients. Although there were no difference in UPDRS-3 scores in the quartiles of ΔNFA, the highest quartile was associated with H-Y stage ≥3 [OR 2.99, 95% confidence interval (CI 1.33-6.70, p = 0.008] after adjustment for age, sex and comorbid orthopedic spinal lesions. The highest quartile of ΔTLA was associated with comorbid orthopedic spinal lesions [OR 5.83 (1.42-23.8, p = 0.014], and UPDRS-3 score [OR 3.04 (1.80-5.15/10 points, p<0.0001]. CONCLUSION: Thoraco-lumbar AP was associated with UPDRS-3 scores and orthopedic spinal lesions, and in contrast, neck AP was not associated with these factors, suggesting that they had different pathomechanisms.

    To explore hemorrhage risk and the clinical significance of abnormal change of prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (FIB), plasma thrombin time (TT) and d-dimer (D-D) in de novo acute leukemia (except for APL), the different bleeding manifestations of 114 cases of de novo acute leukemia with different coagulation indexes were analyzed retrospectively. The correlation between these blood coagulation indexes and the possible correlative clinical characteristics were analysed, including age, sex, type of acute leukemia, initial white blood cell(WBC) and platelet(Plt) count, the proportion of blast cells in bone marrow and cytogenetic abnormality of patients at diagnosis. The results indicated that the incidence of abnormal blood coagulation was as high as 78.1% for de novo AL patients. These patients with 5 normal blood coagulation indexes may have mild bleeding manifestation, but the more abnormal indexes, the more severe bleeding. Both PT and D-D were sensitive indexes for diagnosis of level II bleeding. Incidence of abnormal blood coagulation significantly correlates with the proportion of blast cells in bone marrow (χ(2) = 4.184, OR = 1.021, P coagulation. It is concluded that the coagulation and fibrinolysis are abnormal in most patients with de novo acute leukemia. More abnormal indexes indicate more severe bleeding, and both PT and D-D are sensitive indexes for diagnosis of level II bleeding. Higher proportion of blast cells in bone marrow predicts higher incidence of abnormal blood clotting. Acute leukemia with elderly age, high white blood cell count and adverse cytogenetics do not predict severer abnormal blood clotting. Detection of PT, APTT, TT, FIB, and D-D may help to judge whether the patients are in a state of hypercoagulability or disseminated intravenous coagulation, which will provide experiment evidences for early intervention and medication.

    The aim of this study was to investigate the clinical and laboratorial characteristics of splenic marginal zone lymphoma (SMZL) with an abnormal complete blood count (CBC). Data of 19 newly diagnosed SMZL patients with abnormal CBC were analyzed retrospectively. Seven patients were diagnosed by using splenic histology, 12 patients who did not undergo splenectomy were diagnosed on the basis of typical clinical presentation and cytologic, immunophenotypic and histologic characteristics of peripheral blood and bone marrow, according to SBLG guidelines. The results showed that leukocytosis (≥ 10.0×10(9)/L) was seen in 5 cases (26.3%); leukocytopenia (complete response was achieved in 9 out of 11 (81.8%) patients. It is concluded that SMZL with abnormal CBC has a higher incidence of cytopenia, bone marrow involvement and autoimmune phenomena. Therapeutic strategies consisting of Rituximab show a better efficacy.

    Study Design Cross-sectional clinical assessment. Background Patellar tendinopathy is not always accompanied by patellar tendon abnormalities (PTAs). Thus, clinical screening tools to help identify patients with patellar tendon pain who have PTAs could enhance clinical decision making and patient prognosis. Objectives To test the diagnostic accuracy of the Victorian Institute of Sport Assessment-Patella (VISA-P) questionnaire, a single-leg decline squat (SLDS), tendon pain history, age, and years of sports participation to identify athletes with symptomatic patellar tendons who have PTAs confirmed on imaging. Methods Data provided by ultrasound examination, the VISA-P questionnaire, the SLDS, tendon pain history, age, and years of sport participation were collected in 43 athletes. A classification and regression tree (CART) model was developed to verify variables associated with PTA occurrence. Likelihood ratios (LRs) were computed for positive and negative tests. Results The SLDS, VISA-P questionnaire, and tendon pain history were associated with PTA occurrence. Athletes with negative results on all 3 tests (CART model) had a lower likelihood of having PTAs (negative LR = 0.3; 95% confidence interval [CI]: 0.2, 0.5). The isolated use of the SLDS or tendon pain history (positive LR = 4.2; 95% CI: 2.3, 7.14 and 4.5; 95% CI: 1.8, 11.1, respectively) had similar influence on probability of PTA presence compared to the CART model (positive LR = 4.1; 95% CI: 2.5, 6.3). Conclusion Although the objective was to investigate a clinical test to identify PTAs, the combined use of the tests had greater accuracy to identify individuals without PTAs.

    Klopper Joshua P

    2007-06-01

    Full Text Available Abstract A 12-year-old girl presented with a 4 year history of an enlarged, firm thyroid gland. On exam, her thyroid was firm and fixed and an enlarged cervical lymph node was palpable as well. Though a thyroid ultrasound prior to referral was read as thyroiditis, clinical suspicion for thyroid carcinoma mandated continued investigation. The diagnosis of papillary thyroid cancer was established and her workup revealed lymph node metastases as well as a tremendous burden of pulmonary metastases. Pediatric thyroid cancer is extremely rare, but often presents with aggressive disease. Palpable thyroid abnormalities in an individual under 20-years-old should be viewed with suspicion and should be thoroughly investigated to rule out malignancy even in the face of negative diagnostic procedures. Though pediatric papillary thyroid cancer often presents with loco-regional and even distant metastatic disease, mortality rates in follow-up for as long as 20 years are very favorable.

    Full Text Available Objective To investigate the clinical and EEG features of ischemic stroke patients with abnormal discharges.  Methods Clinical data and 24-hour EEG monitoring of 162 ischemic stroke patients were analyzed retrospectively. One-year follow-up was carried out and post-ischemic epilepsy was diagnosed.  Results Among 162 ischemic stroke patients, 24-hour EEG was abnormal in 87 cases (53.70%. According to the correspondence of site of infarcts and abnormal discharges, these 87 cases were classified into 2 groups: matched group (N = 24, 27.59% and unmatched group (N = 63, 72.41%. There was no significant difference between 2 groups in terms of Oxfordshire Community Stroke Project (OCSP and TOAST classification (P = 0.792, 0.111, while there was significant difference between 2 groups on the site of infarcts (P = 0.000. In matched group, the infarcts were mainly located in cortex (N = 23, 95.83%. However, in unmatched group, the infarcts were mainly located in cortex and basal ganglia (N = 27, 42.86%, or in basal ganglia only (N = 24, 38.10%. In matched group, 24-hour EEG showed slowing of background activities, and sharp waves and sharp and slow wave complex which were corresponding to the infarct sites. The abnormal discharges could only be recorded around the infarct unilaterally. In unmatched group, the epileptiform discharges were recorded in both contralateral and ipsilateral ischemic hemispheres, usually with widespread slow waves and asymmetric background. The infarcts were limited, but abnormal discharges were widespread. For example, the infarct was located in deep brain, while scalp abnormal discharges were recorded. Although there was no significant difference in terms of epilepsy incidence between 2 groups (P = 0.908, the types of epilepsy were statistically different between 2 groups (P = 0.000. In matched group, the main type was partial seizure. But in unmatched group, the main types of epilepsy were secondary generalized seizure and

    The article analyses the significance of the concept of "obsession" in nineteenth-century alienism. From a clinical point of view, Esquirol's description was completed by other authors (Jules Falret, Legrand du Saulle). In the area of psychopathological studies, French alienism, with Morel's emotional delirium or Janet's psychasthenia, defended the emotional theory, as opposed to the intellectual disorder proposed by German doctors. Lastly, the importance of the cultural framework is stressed in the appearance of obsessive symptoms and their interpretation. Along these lines, the article discusses the relationship of religious scruples to melancholy or the appearance of diagnostic categories subject to fin de siècle codes and mentalities.

    2013-12-01

    Full Text Available Aim. The objective of this study is to determine whether and how metabolic abnormalities are associated with clinical symptoms and cognitive performance in schizophrenia. Methods. 46 adult patients with schizophrenia taking first- or second generation antipsychotics were included in the study. The following data were collected: BMI, abdominal circumference, lipid panel and blood glucose, blood pressure and treatment of comorbidities. Clinical symptoms were assessed using PANSS, CDSS, CGI and SAS scales. Cognitive performance was assessed using CNS Vital Signs computerized battery of tests: Verbal Memory test, Visual Memory test, Finger Tapping Test, Symbol Digit Coding, Stroop Test, Shifting Attention Test, and Continuous Performance Test. Results. Dyslipidemia, raised LDL and raised blood glucose levels were the best predictors of more severe clinical symptoms (PANSS, PANSS P, PANSS G, CGI and lower neurocognitive index, worse cognitive flexibility, executive functions, complex attention composite memory, verbal memory, slower reaction time and worse performance in SAT, CPT, ST tests. Obesity was associated with worse results in VBM, VIM, FTT, SDC tests. Raised blood pressure was associated with improvements in all cognitive domains and better performance in SAT, CPT, ST tests. Discussion. There are several weak associations between severity of clinical symptoms and metabolic abnormalities. Most of these were for blood glucose levels and raised blood glucose. Lipids and glucose abnormalities are the best predictors of deteriorated cognitive performance. Contrary to previous observations, raised blood pressure was associated with better results in cognitive tests. Conclusions. These findings indicate that cognitive impairment and metabolic abnormalities may be linked in patients with schizophrenia

    Full Text Available Background Minor head trauma accounts for 70% to 90% of all head traumas. Previous studies stated that minor head traumas were associated with 7% - 20% significant abnormal findings in brain computed tomography (CT-scans. Objectives The aim of this study was to reevaluate clinical criteria of taking brain CT scan in patients who suffered from minor head trauma. Patients and Methods We enrolled 680 patients presented to an academic trauma hospital with minor head trauma in a prospective manner. All participants underwent brain CT scan if they met the inclusion criteria and the results of scans were compared with clinical examination finding. Results Loss of consciousness (GCS drop or amnesia was markedly associated with abnormal brain CT scan (P < 0.05. Interestingly, we found 7 patients with normal clinical examination but significant abnormal brain CT scan. Conclusions According to the results of our study, we recommend that all patients with minor head trauma underwent brain CT scan in order not to miss any life-threatening head injuries.

    Between the 17th and 20th centuries, blood was transfused from various animal species into patients with a variety of pathological conditions. Skin grafts were carried out in the 19th century, with grafts from a variety of animals, with frogs being the most popular. In the 1920s, Voronoff advocated the transplantation of slices of chimpanzee testis into elderly men, believing that the hormones produced by the testis would rejuvenate his patients. In 1963-4, when human organs were not available and dialysis was not yet in use, Reemtsma transplanted chimpanzee kidneys into 13 patients, one of whom returned to work for almost 9 months before suddenly dying from what was believed to be an electrolyte disturbance. The first heart transplant in a human ever performed was by Hardy in 1964, using a chimpanzee heart, but the patient died within 2 h. Starzl carried out the first chimpanzee-to-human liver transplantation in 1966; in 1992 he obtained patient survival for 70 days following a baboon liver transplant. The first clinical pig islet transplant was carried out by Groth in 1993. Today, genetically-modified pigs offer hope of a limitless supply of organs and cells for those in need of a transplant.

    Oatmeal has been used for centuries as a soothing agent to relieve itch and irritation associated with various xerotic dermatoses. In 1945, a ready to use colloidal oatmeal, produced by finely grinding the oat and boiling it to extract the colloidal material, became available. Today, colloidal oatmeal is available in various dosage forms from powders for the bath to shampoos, shaving gels, and moisturizing creams. Currently, the use of colloidal oatmeal as a skin protectant is regulated by the U.S. Food and Drug Administration (FDA) according to the Over-The-Counter Final Monograph for Skin Protectant Drug Products issued in June 2003. Its preparation is also standardized by the United States Pharmacopeia. The many clinical properties of colloidal oatmeal derive from its chemical polymorphism. The high concentration in starches and beta-glucan is responsible for the protective and water-holding functions of oat. The presence of different types of phenols confers antioxidant and anti-inflammatory activity. Some of the oat phenols are also strong ultraviolet absorbers. The cleansing activity of oat is mostly due to saponins. Its many functional properties make colloidal oatmeal a cleanser, moisturizer, buffer, as well as a soothing and protective anti-inflammatory agent.

    With the decline of ovarian hormonal function, from the fifth decade of life, women enter the menopause transition, during which bleeding becomes irregular in duration and time of occurrence. Secondary to ovarian dysfunction, developmental and maturation endometrial anomalies occur, which are clinically translated by abnormal uterine bleeding, which in many cases at this age can be caused by organic lesions (fibroma, polyps, endometritis, endometrial hyperplasia, adenomyosis, etc.). The retrospective study included a total of 256 patients with abnormal uterine bleeding in menopause transition. Statistics showed that the incidence of these types of bleeding increases with age (64.5%) and parity (30.5%), with symptoms consisting mostly in different clinical forms of abnormal uterine bleeding (62.1%), and leiomyomas prevailing at histopathological examination (49.6%). Progesterone replacement therapy was the first therapeutic choice for correcting these types of bleeding. Progesterone therapy is useful not only for therapeutic purposes to amend the bleeding, but also as a precaution against the development of endometrial carcinoma. Progestogens cancel the proliferative and mitogenic effect of estrogens, even when administered in sequential regimen 10-12 days per month.

    Despite longstanding reports of prolonged or reoccurring perceptual changes in a subset of hallucinogen users, very little is known about Hallucinogen Persisting Perception Disorder and related visual abnormalities in hallucinogen users. We used an online questionnaire to document the symptoms and relationship to drug use of unusual visual phenomena in hallucinogen users. 16,192 individuals viewed the information sheet and 2679 were included in the study. Of these, 224 reported having unrelated diagnoses associated with unusual visual experiences and were excluded from main analyses. Most (60.6%) of the remaining 2455 participants reported having experienced drug-free visual experiences that resembled hallucinogen effects. Probability of experiencing constant or near-constant symptoms was predicted by greater past exposure to specific hallucinogens, including lysergic acid diethylamide (LSD). Although symptoms were common, few (104, or 4.2% of the sample) found them distressing or impairing enough to consider seeking treatment. Visual changes in hallucinogen users may be more common than previously suspected and are worthy of further study.

    Electroencephalographic (EEG) abnormalities have been reported during migraine attacks but their spatial and temporal distributions are not well known. We report the temporospatial dynamics of EEG during the full duration of a migraine attack with aura in a 19-year-old woman. She experienced episodes of hemiplegic migraine since the age of 2.5 years, with right hemibody paralysis preceded by visual symptoms. She reported severe pain of the right hemibody just before hemiplegia that was enventually suggestive of possible epileptic seizure, justifying diagnostic video-EEG monitoring. Sporadic hemiplegic migraine was diagnosed in the absence of family history. EEG was normal at the beginning of visual aura. After 15minutes, posterior slow waves appeared over the migrainous hemisphere, spreading progressively towards anterior regions: first the central region (5minutes after onset of contralateral hemiplegia), then the frontal region and over both hemispheres. A new de novo mutation was identified in the SCN1A gene.

    We present our experience in 18 pediatric patients with abnormal neuronal migration. Seven cases of heterotopia of the gray matter, 7 agyria-pachygyria complexes, 1 case of polymicrogyria, 2 cases of schizencephaly and 1 case of hemimegalencephaly were diagnosed by means of ultrasonography, computed tomography and magnetic resonance. The clinical picture was reviewed in each case, with special attention to the occurrence of convulsions, psycho motor development and visual changes. In general, the greater the morphological change, the greater the neurological involvement in these patients. However, the two cases of schizencephaly presented mild clinical expression. Magnetic resonance increases the diagnostic yield in neuronal migration disorders. Nevertheless, either ultrasonography or, especially, computed tomography is useful as a first diagnostic approach in these malformative disorders. (Author)

    Callosal anomalies are frequently associated with other central nervous system (CNS) and/or somatic anomalies. We retrospectively analyzed the clinical features of corpus callosal agenesis/hypoplasia accompanying other CNS and/or somatic anomalies. We reviewed the imaging and clinical information of patients who underwent brain magnetic resonance imaging in our hospital, between 2005 and 2012. Callosal anomalies were isolated in 13 patients, accompanied by other CNS anomalies in 10 patients, associated with only non-CNS somatic anomalies in four patients, and with both CNS and non-CNS abnormalities in four patients. Out of 31 patients, four developed normally, without impairments in motor or cognitive functions. Five of nine patients with cerebral palsy were accompanied by other CNS and/or somatic anomalies, and showed worse Gross Motor Function Classification System scores, compared with the other four patients with isolated callosal anomaly. In addition, patients with other CNS anomalies also had a higher seizure risk.

    Brain death is defined as the permanent, irreversible and concurrent loss of all brain and brain stem functions. Brain death diagnosis is based on clinical criteria and it is not routine to use paraclinical studies. In some countries, electroencephalogram (EEG) is performed in all patients for the determination of brain death while there is some skepticism in relying on EEG as a confirmatory test for brain death diagnosis. In this study, we assessed the validity of EEG and its abnormalities in brain death diagnosis. In this retrospective study, we used 153 EEGs from medical records of 89 brain death patients in organ procurement unit of the Iranian Tissue Bank admitted during 2002-2008. We extracted and analyzed information including EEGs, which were examined by a neurologist for waves, artifacts and EEG abnormalities. The mean age of the patients was 27.2±12.7 years. The most common cause of brain death was multiple traumas due to accident (65%). The most prevalent artifact was electrical transformer. 125 EEGs (82%) were isoelectric (ECS) and seven EEGs (5%) were depictive of some cerebral activity which upon repeat EEGs, they showed ECS patterns too. There was no relationship between cause of brain death and cerebral activity in EEGs of the patients. In this study, we could confirm ECS patterns in all brain death patients whose status had earlier been diagnosed clinically. Considering the results of this study, it seems sensible to perform EEG as a final confirmatory test as an assurance to the patients' families.

    The author discusses ways to make the history of psychology course relevant for a clinical psychology doctoral program within a multidenominational Protestant theological seminary. She uses a personalist orientation to emphasize the need to integrate psychology, philosophy, and theology. She differentiates among the intrapersonal, interpersonal, impersonal, and transpersonal dimensions of experience. She illustrates the rich multidisciplinary historical roots of contemporary psychology by tracing the the history of the term psychology and examining its meanings in the existential psychology of Søren Kierkegaard and in the 19th-century novel. She includes brief histories of the "new psychology" and of the unconscious. She describes how she uses the field of psychotheological integration to illustrate principles of historiography and summarizes resources used to supplement traditional textbooks.

    Radiographer's roles have evolved with their scope broadening over the last 20 years culminating in the development of advanced and consultant posts. Yet one development has not been embraced, despite being inherent in medicine and a common extension of nurse and other allied health professionals' roles, is that of clinical assessment. This article explores the evolving role of the radiographer and discusses whether this should include skills in clinical history taking and physical examination. Issues for education and development will be addressed together with examples of current and potential roles.

    Full Text Available Due to the signifi¬cant increase of complications developing in young people suffering from low cardiac abnormalities, detection of this disease is important. The aim of the study was to analyze the prevalence and structure of cardiovascular diseases in persone aged 18-21 years who have referred to the medical center of Dnepropetrovsk Medical Academy in the period from 2012 to 2013 in order to determine the mode of physicol exercises. We examined 268 students of 1-2 courses of medical academy, who, along with the clinical examination underwent standard echocardiography 2 times a year. It is established that in the structure of cardiovascular diseases in the studied group small anomalies of the heart occupy the first place; valve pathology the second place. In the structure of small abnormality of the heart, mitral valve prolapse is detected the most frequently. Since this anomaly affects the level of tolerance to physical stress and can lead to heart disorder, routine screening of patients with this disease is mandatory and must be carried out to address the choice of the level of physical activity.

    The aim of this retrospective study was to assess prevalence, risk factors, clinical presentation and outcome of phenobarbitone induced haematological abnormalities (PBIHA) in dogs. The medical records of two veterinary referral institutions were searched for dogs diagnosed with idiopathic epilepsy and treated with PB as monotherapy or polytherapy between March 2003 and September 2010. Sixteen dogs had PBIHA; the median age at diagnosis was 69.5 months. Phenobarbitone was administered at a median dose of 3 mg/kg twice a day for a median period of 100.5 days and the median serum phenobarbitone level was 19 μg/ml. Two dogs had neutropenia, three had anaemia and thrombocytopenia, two had anaemia and neutropenia; the remaining nine had pancytopenia. All dogs were referred for non-specific clinical signs. Phenobarbitone was discontinued after diagnosis, and the median time to resolution of PBIHA was 17 days. The prevalence and risk factors for PBIHA were evaluated from a questionnaire survey of referring practices to obtain more detailed follow-up on cases diagnosed with idiopathic epilepsy. The prevalence rate of PBIHA was 4.2%, and the condition occurred in dogs treated with standard therapeutic doses often within the first three months after starting treatment. Serial haematological evaluations should be therefore considered from the beginning of phenobarbitone therapy to allow early diagnosis and treatment of PBIHA.

    Full Text Available Abstract Background There is considerable evidence from the literature that children with chronic lung disease of infancy (CLD have abnormal pulmonary function in childhood and this could have an impact on their life quality and overall health. There are similarities between CLD and asthma, and corticosteroids are the mainstay treatment for asthma. Many physicians use inhaled corticosteroids in children with CLD with no evidence. Therefore we wish to conduct a randomized double-blinded placebo controlled trial to test for the role of inhaled corticosteroids in children aged from3 to 9 years with a history of CLD. Our primary hypothesis will be that inhaled corticosteroids are beneficial in children with CLD. Methods Our primary hypothesis is that using inhaled steroids; Beclomethasone Dipropionate (QVAR 100 mcg 2 puffs 2 times a day for 6 weeks will improve the respiratory system resistance and the quality of life in children with CLD. Discussion We propose that Beclomethasone Dipropionate (QVAR will affect the pulmonary function after 6 weeks of treatment. In summary we think that our study will highlight knowledge on whether the use of inhaled steroids is clinically effective for CLD.

    The clinical usefulness of plasma abnormal prothrombin, defined as a protein induced by vitamin K absence or antagonist-II: PIVKA-II, as a tumor marker for hepatocellular carcinoma (HCC), was evaluated. Plasma PIVKA-II concentration was determined by an enzyme-linked immunosorbent assay (ELISA) using a monoclonal antibody specific for PIVKA-II. Forty-one (65%) out of 63 patients with HCC had an abnormal PIVKA-II level above 0.13 arbitrary units (AU)/ml; the level was above 0.3 AU/ml in 33 patients (52%) and above 0.5 AU/ml in 27 patients (43%). On the other hand, most of the 282 patients with various liver diseases other than HCC had normal or slightly elevated levels of PIVKA-II. Their values were all below 0.5 AU/ml, with the exception of 2 patients with decompensated liver cirrhosis. The patients with PIVKA-II values above 0.5 AU/ml were strongly suspected of having HCC. Plasma PIVKA-II levels were not related to serum alpha-fetoprotein (AFP) levels, but were above 0.5 AU/ml in 14 (44%) out of the 32 patients whose serum AFP levels were below 400 ng/ml. In some patients with HCC, PIVKA-II was increased throughout the course of the disease, and in others it normalized after surgical resection of the tumor. We conclude that the plasma PIVKA-II assay by the ELISA method using a monoclonal antibody is a useful diagnostic tool for monitoring HCC, particularly in HCC patients with low AFP levels.

    One hundred years ago, in 1909, the American Society for Clinical Investigation (ASCI) held its first annual meeting. The founding members based this new society on a revolutionary approach to research that emphasized newer physiological methods. In 1924 the ASCI started a new journal, the Journal of Clinical Investigation. The ASCI has also held an annual meeting almost every year. The society has long debated who could be a member, with discussions about whether members must be physicians, what sorts of research they could do, and the role of women within the society. The ASCI has also grappled with what else the society should do, especially whether it ought to take a stand on policy issues. ASCI history has reflected changing social, political, and economic contexts, including several wars, concerns about the ethics of biomedical research, massive increases in federal research funding, and an increasingly large and specialized medical environment.

    Full Text Available Background: Magnetic resonance imaging (MRI helps in the diagnosis of neurologic Wilson′s disease (WD. The literature regarding MR spectroscopy (MRS and diffusion-weighted imaging (DWI in WD is limited. Objectives: To evaluate the clinical features and neuroimaging findings in drug-naοve neurologic WD and to find correlation between clinical stage and disease duration with different imaging findings. Materials and Methods: The study subjects included consecutive and follow-up neurologic WD patients attending movement disorder clinic. The initial clinical and MRI features before commencement of chelation therapy were noted. Of 78 patients, 34 underwent DWI study and MRS was done in 38 patients and in 32 control subjects. Results: Dystonia, dysarthria, tremor, and behavioral abnormality were common presenting features. All patients had MRI abnormality with major affection of basal ganglia. The clinical severity and anatomical extent of MRI abnormalities were positively correlated (P < 0.001; r s = 0.709. Presence of diffusion restriction was inversely related to duration of disease (P < 0.001; r s = 0.760. WD patients had reduced N-acetylaspartate/creatine (Cr and choline (Cho/Cr ratio (P < 0.001 as compared with control subjects in MRS study. Conclusion: Dystonia, dysarthria and tremor are common neurological features of WD. In this study, MRI abnormalities were positively correlated with disease severity; diffusion restriction was inversely correlated with the duration of the disease process. MRS was also a sensitive tool for diagnosing patient of neurologic WD.

  1. Abnormal Neural Responses to Emotional Stimuli but Not Go/NoGo and Stroop Tasks in Adults with a History of Childhood Nocturnal Enuresis.

    Mengxing Wang

    Full Text Available Nocturnal enuresis (NE is a common disorder in school-aged children. Previous studies have reported that children with NE exhibit structural, functional and neurochemical abnormalities in the brain, suggesting that children with NE may have cognitive problems. Additionally, children with NE have been shown to process emotions differently from control children. In fact, most cases of NE resolve with age. However, adults who had experienced NE during childhood may still have potential cognitive or emotion problems, and this possibility has not been thoroughly investigated.In this work, we used functional magnetic resonance imaging (fMRI to evaluate brain functional changes in adults with a history of NE. Two groups, consisting of 21 adults with NE and 21 healthy controls, were scanned using fMRI. We did not observe a significant abnormality in activation during the Go/NoGo and Stroop tasks in adults with a history of NE compared with the control group. However, compared to healthy subjects, young adults with a history of NE mainly showed increased activation in the bilateral temporoparietal junctions, bilateral dorsolateral prefrontal cortex, and bilateral anterior cingulate cortex while looking at negative vs. neutral pictures.Our results demonstrate that adults with a history of childhood NE have no obvious deficit in response inhibition or cognitive control but showed abnormal neural responses to emotional stimuli.

    Full Text Available Introduction: Minor blunt head trauma is a common reason for children to present to the emergency department (ED. Crania computed tomography (CT is the choice for evaluating children with blunt head trauma in the ED, but few shows abnormal findings. In this study, we aim to evaluate CT findings in children with blunt head trauma and clinical symptoms to identify clinical predictors of abnormal CT scans. Methods: In this prospective study, 218 children under 2 years of age (121 male and 97 female with mean age of 11.24 ± 4.31 months with compliant of minor blunt head trauma visiting the ED between April 2011 and April 2014 were included. Physical examination and clinical symptoms, as well as CT findings and patients’ outcome were evaluated. Results: Physical examinations were normal in 95.9%, and clinical symptoms were present only in 25.7% including vomiting in 16.1%, loss of consciousness (LOC in 8.3%, ear/nose bleeding in 4.1% and seizure in 5.5%. CT scan was requested in 189 cases (86.7% of which, 7.9% were abnormal including linear fracture in 5.3%, subgaleal hematoma in 1.1% and depressed fracture, subcutaneous hematoma and intracranial hemorrhage (ICH each in 0.5%. Among all cases, 89.0% were discharged from ED with no further observation, 6.0% discharged after 48 h observation and 5.0% were hospitalized. There was a significant correlation between abnormal CT findings and having any clinical symptoms, vomiting and Ear/nose bleeding. Conclusion: In children under 2 years old with minor blunt head trauma, most CT scans are unnecessary. Considering clinical symptoms as predictors of abnormal CT scans we can reduce unnecessary ones.

    Objectives To evaluate the values of abnormal heart rate recovery (HRR) after treadmill exercise test in patients with coronary artery disease (CAD). Methods One hundred and seventy-eight consecutive cases of suspected CAD who underwent symptom-limited treadmill exercise test (TET) and coronary angiography (CAG) were enrolled and di-vided into normal and abnormal HRR group based on the status of the values of HRR one or two minutes after TET. The clinical characteristics, TET parameters and CAG results of the two groups were compared attempted to assess the value of HRR on patients with CAD. Results (1) The cases of smoking, diabetes mellitus (DM) and ST segment de-viation at rest in abnormal HRR group were more significantly than those in normal HRR group (all P < 0. 05). (2) The subjects of abnormal HRR usually had higher basal heart rate, more cases exhibited ST segment abnormality and or exercise-limited angina during or after TET(P<0.01 and P<0.05, respectively), but lower level of peak heart rate attained (P<0.05) than those in normal group. The values of metabolism equivalents and duration of TET between the two groups displayed phenomenal difference (P<0.05). There were more samples acquired moderate to high level of Duke test score and chronotropic incompetence in the group of abnormal HRR, compared to the normal HRR group (P<0.01). (3) The cases of negative CAG results in the group of normal and abnormal HRR group were 73 (66.97 % ) and 24 (34.78 %). Cases of significant coronary lesions (at least one major coronary vessel ≥ 50 % stenosis) a-mongst the subgroup of positive CAG were 36 (33.03 % ) and 45 (65.22 %), severe coronary lesions (three-vessel, left main or the equivalents of left main) were 10 (9.17 % ) and 17 (24.64 %) for normal and abnormal HRR respec-tively (P<0.01). Accordingly, the Gensini scores in the subunit of abnormal HRR increased. (4)Linear correlation analysis indicate there was a negative correlation between the values of HRR in

    The cerebral palsy(CP) encephalopathies are often of uncertain etiology and various functional image findings comparing with anatomical image findings have been reported. However, only a few have mentioned its clinical implications. The purpose of our report is to compare clinical severity and functional SPECT abnormalities of thalami and cerebellum in CP patients with normal MRI. Thirty six CP patients with bilateral spastic palsy who had normal MRI and brain SPECT were studied from July 1996 to September 1997. The patients' age at the time of SPECT was 22.84{+-}17.69 months. The patients were divided into two groups according to motor quotient(MQ); moderate defect (>50MQ : n=27 MQ=22.78{+-}10.36), mild defect (<50MQ : n=9, MQ=66.11{+-}13.87). The degree of rCBF decrease between the two groups was evaluated by {chi}{sup 2} test. Brain SPECT was performed following IV administration of 0.05-0.1 mCi/kg (minimum 2.0 mCi) of Tc-99m ECD and chloral hydrate sedation (50-80 mg/kg p.o) using a triple head system (MS 3, Siemens). Interpretation of brain SPECT was visual analysis: severe decrease is defined when the defect is moderate to marked and mild decrease in rCBF as mild. Seven of 36 (19.4%) showed unilateral or bilateral moderate decrease in rCBF in thalami, 20(55.6%) showed mild decrease, and 9(25.0%) showed no decreased rCBF. All 7 who had moderate thalamic defect reveled moderate motor defect clinically. Ten of 36(27.9%) revealed unilateral or bilateral moderate rCBF defect, 23 (63.9%) depicted mild defect, and 3(8.3%) showed no defect. Sixteen with moderate thalamic rCBF defect showed moderate motor defect in 15 patients. There was statistically significant (p=0.02605) relationship between rCBF defect and motor defect in our CP patients. In conclusion, brain SPECT appears sensitive, non-invasive tool in the evaluation as well as in the prognostication of bilateral spastic cerebral palsy patients and deserves further study using larger number of patients.

    BACKGROUND: Myasthenia gravis (MG) is an autoimmune disease which mainly affects neuromuscular junctions. The ages, modified Osserman classification and clinical manifestation and humoral immunol function of MG with and without thymic abnormality are different.OBJECTIVE: To explore the clinical manifestation and humoral immuno-function of MG with abnormal and normal thymus gland.DESIGN: Contrast observation.SETTING: Department of Neurology, the Third Affiliated Hospital of Sun Yat-sen University.PARTICIPANTS: A total of 49 inpatients with MG were selected from the Third Affiliated Hospital of Sun Yat-sen University from March 2000 to August 2005. All the patients had typical clinical manifestation of MG and positive neostigmine test. All the patients knew and agreed the laboratory examinations. There were 22 males and 27 females of 2-69 years old. Chest MRI or CT scan were performed to reveal thymus gland abnormality. According to whether there was tumor in superior mediastinum, all patients were divided into 2 groups, abnormal and normal groups. Normal thymus gland group (n=30) contained 16 males and 14 famales of 6-43 years old. Abnormal thymus gland group (n=19) contained 6 male and 13 female of 2-69years old.METHODS: ① All patients were questioned about initial symptoms. Meanwhile, main clinical manifestations were recorded at hospital admission. ② 7180A automatic biochemical analyzer and automatic microplate reader were used in detecting seroimmunity index. The levels of C3, C4, IgG, IgA, IgM and CH50 in blood serum were analyzed by nephelometry. ③ Clinical classification is based on modified Osserman classification. The patients with MG were divided into six types: Ⅰ (Ocular myasthenia), Ⅱ a (Mild generalized myasthenia), Ⅱ b (Moderately severe generalized myasthenia), Ⅲ (Acute fulminating myasthenia), Ⅳ (Late severe myasthenia).MAIN OUTCOME MEASURES: ① Differences of initial symptoms and clinical manifestation of two group patients.

    Certain qualitative abnormalities in neutrophils and blood monocytes are associated with frequent, severe, and recurrent bacterial infections leading to fatal sepsis, while other qualitative defects demonstrated in vitro may have few or no clinical sequelae. These qualitative defects are discussed in terms of the specific functions of locomotion, phagocytosis, degranulation, and bacterial killing.

  7. A brief history of placebos and clinical trials in psychiatry.

    Science.gov (United States)

    2011-04-01

    The history of placebos in psychiatry can be understood only in the context of randomized controlled trials (RCTs). Placebo treatments are as old as medicine itself, and are particularly effective in dealing with psychosomatic symptoms. In psychiatry, placebos have mainly been featured in clinical drug trials. The earliest controlled trial in psychiatry (not involving drugs) occurred in 1922, followed by the first crossover studies during the 1930s. Meanwhile the concept of randomization was developed during the interwar years by British statistician Ronald A Fisher, and introduced in 3 trials of tuberculosis drugs between 1947 and 1951. These classic studies established the RCT as the gold standard in pharmaceutical trials, and its status was cemented during the mid-1950s. Nevertheless, while the placebo became established as a standard measure of drug action, placebo treatments became stigmatized as unethical. This is unfortunate, as they constitute one of the most powerful therapies in psychiatry. In recent years, moreover, the dogma of the placebo-controlled trial as the only acceptable data for drug licensing is also being increasingly discredited. This backlash has had 2 sources: one is the recognition that the US Food and Drug Administration has been too lax in permitting trials controlled with placebos alone, rather than also using an active agent as a test of comparative efficacy. In addition, there is evidence that in the hands of the pharmaceutical industry, the scientific integrity of RCTs themselves has been degraded into a marketing device. The once-powerful placebo is thus threatened with extinction.

    Canine monocytic ehrlichiosis is a tick borne disease caused by Ehrlichia canis, an obligate intracellular rickettsial organism belonging to the family Anaplasmataceae. Canine ehrlichiosis causes hemaotological changes among infected animals which could be used as a potential predictor for diagnosing canine monocytic ehrlichiosis (CME). Ninety-four blood samples were obtained from canines that either presented for a routine health check-up or for clinical illness. A history, physical and laboratory test were conducted on each animal. All samples were examined for E. canis using a 16S rDNA polymerase chain reaction (PCR) amplification to confirm CME infection. Thirty-six of the samples were positive for E. canis using PCR and the rest were negative. The Mann-Whitney and chi-square test were used to compare the differences between the PCR-positive and negative animals. PCR-positive animals had a higher mean body temperature than PCR-negative animals. The following were significantly lower in PCR-positive animals: white blood cell count, eosinophil count, red blood cell count, hemoglobin, hematocrit, platelet count, and the random distribution of width (RDW) of the red blood cells. We evaluated complete blood cell count findings to determine factors associated with CME using multivariable logistic regression analysis and found thrombocytopenia was significantly associated with CME (OR = 0.085; 95% CI: 0.78-0.92, p < 0.001). For every decrease in the platelet count of 10,000 there was a 15% increase in the likelihood of having CME.

    Full Text Available SUMMARY Objective: to determine the positive predictive value of clinical history in comparison with urodynamic study for the diagnosis of urinary incontinence. Methods: retrospective analysis comparing clinical history and urodynamic evaluation of 1,179 women with urinary incontinence. The urodynamic study was considered the gold standard, whereas the clinical history was the new test to be assessed. This was established after analyzing each method as the gold standard through the difference between their positive predictive values. Results: the positive predictive values of clinical history compared with urodynamic study for diagnosis of stress urinary incontinence, overactive bladder and mixed urinary incontinence were, respectively, 37% (95% CI 31-44, 40% (95% CI 33-47 and 16% (95% CI 14-19. Conclusion: we concluded that the positive predictive value of clinical history was low compared with urodynamic study for urinary incontinence diagnosis. The positive predictive value was low even among women with pure stress urinary incontinence.

    2007-04-01

    Full Text Available Abstract Background Liver function tests (LFTs are routinely performed in primary care, and are often the gateway to further invasive and/or expensive investigations. Little is known of the consequences in people with an initial abnormal liver function (ALF test in primary care and with no obvious liver disease. Further investigations may be dangerous for the patient and expensive for Health Services. The aims of this study are to determine the natural history of abnormalities in LFTs before overt liver disease presents in the population and identify those who require minimal further investigations with the potential for reduction in NHS costs. Methods/Design A population-based retrospective cohort study will follow up all those who have had an incident liver function test (LFT in primary care to subsequent liver disease or mortality over a period of 15 years (approx. 2.3 million tests in 99,000 people. The study is set in Primary Care in the region of Tayside, Scotland (pop approx. 429,000 between 1989 and 2003. The target population consists of patients with no recorded clinical signs or symptoms of liver disease and registered with a GP. The health technologies being assessed are LFTs, viral and auto-antibody tests, ultrasound, CT, MRI and liver biopsy. The study will utilise the Epidemiology of Liver Disease In Tayside (ELDIT database to determine the outcomes of liver disease. These are based on hospital admission data (Scottish Morbidity Record 1, dispensed medication records, death certificates, and examination of medical records from Tayside hospitals. A sample of patients (n = 150 with recent initial ALF tests or invitation to biopsy will complete questionnaires to obtain quality of life data and anxiety measures. Cost-effectiveness and cost utility Markov model analyses will be performed from health service and patient perspectives using standard NHS costs. The findings will also be used to develop a computerised clinical decision

    Karyotypic abnormalities were detected in the malignant cells of 6 of 18 patients with multiple myeloma (MM). Six patients with benign monoclonal gammopathy, one with amyloidosis of immunoglobulin origin, and two with Waldenstroem's macroglobulinemia had normal karyotypes. All six MM patients with aneuploidy were in a group of 10 patients in an accelerated or relapse phase of their disease and four had high serum paraprotein levels when their abnormal karyotypes were detected. Five of the 6 MM patients with aneuploidy had received prior chemotherapy. Aneuploidy was not observed in 8 stable MM patients. Abnormalities of chromosome 14 were present in all 6 patients. A translocation between Nos. 11 and 14 was found in aneuploid cells of 2 patients who had plasma cell leukemia (PCL). A deletion of chromosome 6 was detected in 2 MM patients and a pericentric inversion of No. 6 was seen in the patient with PCL. Three of 4 MM patients had a nonrandom loss of one chromosome 8. Two other MM patients developed acute nonlymphocytic leukemia (ANLL) after the diagnosis of MM. Marrow cells of one patient showed a 5q- chromosome and a constitutional translocation involving Nos. 13 and 14 during the preleukemic stage; during the leukemic phase, the karyotype evolved to 50 chromosomes including extra chromosomes 1, 6, 8, 10, and 21 and a missing 7, in addition to the originally detected 5q- and the 13/14 translocation.The peripheral blood from the other patient was hypodiploid, with a missing chromosome 7 and a translocation between 3q and 9p. These patterns of chromosome change resemble those of ANLL rather than MM and are similar to the changes seen in ANLL after treated malignant lymphoma.

    Thirty-four patients with bone tumours and tumour-like abnormalities of the skeleton, of varying ages, were examined by a computer-aided diagnostic programm; the accuracy, clinical usefullness and specific advantages and disadvantages of the programm have been evaluated. This was done by two statistical methods, both with showed high accuracy and reliability of the system (97% and 88,2%). In addition to the diagnostic results, the growth rate of the lesion could be estimated. This indicates the biological behaviour of the tumour independently of the histological diagnosis.

    Background Vitiligo is an acquired pigmentary skin disorder affecting 0.1-4% of the general population. The nails may be affected in patients with an autoimmune disease such as psoriasis, and in those with alopecia areata. It has been suggested that nail abnormalities should be apparent in vitiligo patients. Objective We sought to document the frequency and clinical presentation of nail abnormalities in vitiligo patients compared to healthy volunteers. We also examined the correlations between nail abnormalities and various clinical parameters. Methods This study included 100 vitiligo patients and 100 healthy subjects. Full medical histories were collected from the subjects, who underwent thorough general and nail examinations. All nail changes were noted. In the event of clinical suspicion of a fungal infection, additional mycological investigations were performed. Results Nail abnormalities were more prevalent in the patients (78%) than in the controls (55%) (p=0.001). Longitudinal ridging was the most common finding (42%), followed by (in descending order): leukonychia, an absent lunula, onycholysis, nail bed pallor, onychomycosis, splinter hemorrhage and nail plate thinning. The frequency of longitudinal ridging was significantly higher in patients than in controls (p<0.001). Conclusions Nail abnormalities were more prevalent in vitiligo patients than in controls. Systematic examination of the nails in such patients is useful because nail abnormalities are frequent. However, the causes of such abnormalities require further study. Longitudinal ridging and leukonychia were the most common abnormalities observed in this study. PMID:27579738

    The prevalence of radiological abnormalities of the sacroiliac joints, the manubriosternal joint, and the lumbar spine were assessed, and quantitative sacroiliac scintigraphy was performed in 151 patients with a history of chronic inflammatory back pain and in 31 controls with non-inflammatory back pain. Sacroiliitis was found in 124 patients (82%), manubriosternal lesions in 84 patients (56%), and lesions of the lumbar spine in 58 patients (38%). In 19 patients (13%), manubriosternal lesions provided the sole radiological abnormality and in five patients (3%) no radiological abnormality could be demonstrated at any of these sites. Quantitative sacroiliac scintigraphy showed increased values in 69 of 137 patients examined (50%), but also in 10 out of 12 control patients with disc degeneration (83%) and is, therefore, nonspecific for inflammatory lesions. Radiological examination of the manubriosternal joint is recommended in patients with inflammatory back pain without radiographic evidence of sacroiliitis.

    Genomics-based non-invasive prenatal screening using cell-free DNA (cfDNA screening) was proposed to reduce the number of invasive procedures in current prenatal diagnosis for fetal aneuploidies. We review here the clinical and ethical issues of cfDNA screening. To date, it is not clear how cfDNA screening is going to impact the performances of clinical prenatal diagnosis and how it could be incorporated in real life. The direct marketing to users may have facilitated the early introduction of cfDNA screening into clinical practice despite limited evidence-based independent research data supporting this rapid shift. There is a need to address the most important ethical, legal, and social issues before its implementation in a mass setting. Its introduction might worsen current tendencies to neglect the reproductive autonomy of pregnant women.

    2015-01-01

    Full Text Available Background: Computed tomography (CT used in pediatric pediatrics brain injury (TBI to ascertain neurological manifestations. Nevertheless, this practice is associated with adverse effects. Reports in the literature suggest incidents of morbidity and mortality in children due to exposure to radiation. Hence, it is found imperative to search for a reliable alternative. Objectives: The aim of this study is to find a reliable clinical alternative to detect an intracranial injury without resorting to the CT. Materials and Methods: Retrospective cross-sectional study was undertaken in patients (1-14 years with blunt head injury and having a Glasgow Coma Scale (GCS of 13-15 who had CT performed on them. Using statistical analysis, the correlation between clinical examination and positive CT manifestation is analyzed for different age-groups and various mechanisms of injury. Results: No statistically significant association between parameteres such as Loss of Consciousness, ′fall′ as mechanism of injury, motor vehicle accidents (MVA, more than two discrete episodes of vomiting and the CT finding of intracranial injury could be noted. Analyzed data have led to believe that GCS of 13 at presentation is the only important clinical predictor of intracranial injury. Conclusion: Retrospective data, small sample size and limited number of factors for assessing clinical manifestation might present constraints on the predictive rule that was derived from this review. Such limitations notwithstanding, the decision to determine which patients should undergo neuroimaging is encouraged to be based on clinical judgments. Further analysis with higher sample sizes may be required to authenticate and validate findings.

    The findings of a previous chest X-ray screening, determined without using standardized criteria, were reassessed by means of the ILO classification. Of 470 radiographs that had been determined as showing asbestos-related changes, 430 were categorized according to the ILO Classification. Small opacities with profusion greater than or equal to 1/0 were described in 39 (52%) of 75 participants who, on the original clinical reading, had been determined as having lung fibrosis, and in 45 (12.7%) of 355 who were determined as having pleural changes only. When considering circumscribed pleural thickening at the chest wall or diaphragm, as categorized by the ILO Classification, such changes were present in 401 (93.7%) of 428 subjects with pleural changes as determined on the clinical reading. In addition to the improved sensitivity and specificity achieved, the ILO Classification also allows comparison with other studies. The most apparent disadvantage of the ILO system is that it cannot firmly separate the various types of asbestos-related pleural changes. The study revealed that the previous asbestos exposure of the case subjects had occurred in many different workplaces and occupations.

    Renal vein thrombosis (RVT) in neonates is a rare condition of low mortality but significant morbidity due to renal impairment.We report the case of a male term newborn with left RVT and elevated serum factor VIII (FVIII).The main symptoms of the patient and the important clinical findings: prompt diagnosis of RVT was possible because the classic clinical presentation of macroscopic hematuria, thrombocytopenia, and palpable flank mass were present in this newborn infant.The main diagnoses: finally, the reason of RVT was established when the infant was 3 months of age: the increased level of FVIII was confirmed. We discuss the diagnosis, therapy, and outcome of the patient and compare with the literature.Therapeutics interventions: however, despite anticoagulant therapy the left kidney developed areas of scarring and then atrophy.Conclusions and outcomes: Prothrombotic defects should be considered in all patients with perinatal RVT. Elevated factor VIII as a reason of RVT in neonatal period is particularly rare. Given a poor renal outcome in children associated with elevated levels of factor VIII, consideration could be given to more aggressive antithrombotic therapy in such cases.

    2012-01-01

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

    The objective of this study is to explore the cause of early abnormal muscle response (AMR) disappearance during microvascular decompression for hemifacial spasm and the clinical outcomes of these patients. Three hundred seventy-two patients received microvascular decompression (MVD) under intraoperative electrophysiological monitoring in Nanjing Drum Tower Hospital in 2014; the characteristic AMR of HFS was observed in 359 patients during the operation. And the 359 patients were divided into two groups based on whether AMR had remained before the beginning of the decompression procedure for offending vessels. Thirty-three patients who showed a permanent disappearance of AMR before the beginning of decompression were regarded as group I. Dural opening and the succeeding CSF drainage produced a permanent disappearance of AMR in 13. During the dissection of lateral cerebellomedullary cistern, a permanent disappearance of AMR was found in 20 patients. Thirty-two patients were cured immediately; delayed resolution (7 days after surgery) was found in one patient. No complications were observed and no recurrence was found during the follow-up period in the 33 patients. In the other 326 patients (group II), AMR disappeared temporarily before the beginning of the decompression procedure for offending vessels in 42 patients. After decompression, AMR disappeared completely in 305 patients. Two hundred sixty-seven patients were cured immediately and 57 patients got a delayed resolution (2 days to 45 weeks after surgery). The two left did not get a complete abolition of spasm. Three cases of hearing loss, one hoarseness, and nine delayed facial paralysis were observed. The reason of early abnormal muscle response disappearance may be that the degree of neurovascular compression was not serious; these patients were more likely to get an immediate cure. Continuous intraoperative electrophysiological monitoring of AMR is necessary.

    Though cortical abnormalities have been demonstrated in moderate and severe traumatic brain injured (TBI) patients, there have been no studies examining cortical changes following blast related mild TBI (mTBI). The purpose of this study was to determine the effects and functional relevance of blast mTBI on cortical thickness in a small cohort of carefully screened blast injured US Service Members (SM). Twelve SM with mTBI acquired through blast injury were compared to 11 demographically matched control SM without TBI. Both mTBI and control participants were active duty and had completed a combat deployment. Subjects underwent MRI examination and the T1 weighted anatomic images were processed using the FreeSurfer suite of tools. Cortical thickness maps were compared between groups and examined for relationships with time since injury (TSI). Utilizing a large database of functional imaging results (BrainMap), significant regions of interest (ROI) were used to determine the behavioral profiles most consistently associated with the specific ROI. In addition, clinical variables were examined as part of post-hoc analysis of functional relevance. Group comparisons controlling for age demonstrated several significant clusters of cortical thinning for the blast injured SM. After multiple comparisons correction (False Discovery Rate (FDR)), two left hemisphere clusters remained significant (left superior temporal (STG) and frontal (SFG) gyri). No clusters were significantly correlated with TSI after FDR correction. Behavioral analysis for the STG and SFG clusters demonstrated three significant behavioral/cognitive sub-domains, each associated with audition and language. Blast injured SMs demonstrated distinct areas of cortical thinning in the STG and SFG. These areas have been previously shown to be associated with audition and language. Post-hoc analyses of clinical records demonstrated significant abnormal audiology reports for the blast injured SM suggesting that the

    Full Text Available Family health history is a leading predictor of disease risk. Nonetheless, it is underutilized to guide care and, therefore, is ripe for health information technology intervention. To fill the family health history practice gap, Cleveland Clinic has developed a family health history collection and clinical decision support tool, MyFamily. This report describes the impact and process of implementing MyFamily into primary care, cancer survivorship and cancer genetics clinics. Ten providers participated in semi-structured interviews that were analyzed to identify opportunities for process improvement. Participants universally noted positive effects on patient care, including increases in quality, personalization of care and patient engagement. The impact on clinical workflow varied by practice setting, with differences observed in the ease of integration and the use of specific report elements. Tension between the length of the report and desired detail was appreciated. Barriers and facilitators to the process of implementation were noted, dominated by the theme of increased integration with the electronic medical record. These results fed real-time improvement cycles to reinforce clinician use. This model will be applied in future institutional efforts to integrate clinical genomic applications into practice and may be useful for other institutions considering the implementation of tools for personalizing medical management.

    Native valve infective endocarditis (IE) in patients with normal valves has increased in the last decades. Whether patients with normal valves present a similar prognosis to those with pathologic valves is unresolved. Our aim is to describe epidemiologic and clinical differences between patients with left-sided IE and normal valves and those with native pathologic valves. We analyzed 945 consecutive episodes of IE, 435 of which involved left-sided nonprosthetic IE. They were classified into 2 groups: episodes in normal valves (normal group, n=173) and episodes in pathologic valves (abnormal group, n=262). Patients in the normal group were younger, Staphylococcus aureus and Streptococcus bovis were more frequently isolated, and vegetations were more frequently found. Heart failure, septic shock, and the need for surgery or death were more common. Multivariate analysis identified the following as factors independently associated with normal valve IE: agevalve IE, patients with IE on normal valves were younger, had a more virulent microbiological profile, developed heart failure and septic shock more frequently, needed more surgical procedures, and had worse prognosis.

    1999-04-01

    The medieval Islamic medical tradition was the direct heir of Classical and Hellenistic medicine thanks to an unprecedented movement of translation into Arabic, commentaries and systematizations of Greek scientific texts. In the process of assimilation, not only theoretical principles, but also literary models of presenting medical knowledge were adopted, amongst them the case history. Since the clinical account can be used as a tool for medical instruction as well as an instrument for professional self-promotion, this study seeks to investigate which purpose most motivated Islamic physicians, and to demonstrate the extent to which they were influenced by the stylistic patterns which served them as a model. This article comprises an analysis of the context, literary devices and purpose of case histories of the Epidemics, Rufus of Ephesos and Galen, and compares them with those by the tenth-century Islamic physician Abu Bakr Muhammad b. Zakariya al-Razi. Author of the largest number of case histories preserved within the medieval Islamic medical literature, al-Razi's clinical records constitute an instrument with which to study and expand medical knowledge as well as providing useful material for students' medical training. Although al-Razi fused elements from the sources which served him as a model, he did not emulate Galen's use of the clinical history to assert himself in order to gain authority and prestige, but remained faithful to the Hippocratic essence.

    Full Text Available Since antiquity, malaria had a major impact on world history but this brief historical overview focuses on clinical features of malaria from Hippocrates to Osler. In antiquity, physicians tried to differentiate malaria from other acute fevers. The classic descriptions of malaria by Hippocrates in ancient Greece and Celsus in ancient Rome are excerpted here from the original Greek and Latin. Their clear clinical descriptions prove malaria was recognized in antiquity. In the modern era, it remains difficult to clinically differentiate malaria from typhoid fever. Since physicians used the term ‘typho-malaria’ to describe acute undifferentiated fevers a testimony to their lack of clinical acumen. Osler, the great clinician, by careful observation in clinical features and fever patterns was able to clearly differentiate malaria from typhoid fever as did the ancients.

    Late-onset noninfectious pulmonary complications (LONIPCs) are life-threatening complications of bone marrow transplantation (BMT). Several pathological patterns are described in the literature with different prognoses, and with different relationships to graft-versus-host disease (GVHD). The role of high-resolution CT (HRCT) is not yet well established. To illustrate different patterns of LONIPCs on HRCT in allogeneic versus autologous BMT in order to investigate the correlation with chronic GVHD (cGVHD). A total of 67 HRCT scans were performed in 24 patients with noninfectious pulmonary disease at least 3 months after BMT (16 allogeneic, 8 autologous). Abnormality patterns and extension on HRCT images were correlated with the clinical outcome and with the severity of cGVHD. Of 24 patients, 9 showed LONIPCs (1 autologous, 8 allogeneic). There was a significant association between abnormalities on HRCT and severe cGVHD (P = 0.038), with no specific pattern. Prognosis seemed to be related to the severity of cGVHD and not to the extent of abnormalities on HRCT. The significant association between abnormalities on HRCT and severe GVHD suggests that LONIPCs can be a pulmonary manifestation of the disease. HRCT is a useful tool when combined with clinical data. (orig.)

  11. Antibiotics and the social history of the controlled clinical trial, 1950-1970.

    Podolsky, Scott H

    2010-07-01

    The histories of antibiotics, controlled clinical trials, and attempts by academics to inculcate an explicitly rational therapeutics among clinicians in the United States were linked during a formative period from 1950 to 1970. Maxwell Finland and Harry Dowling would serve at the epicenter of such efforts in the context of first the broad-spectrum antibiotics, and then, and still more critically, the since-forgotten influx of "fixed-dose combination" antibiotics. With their attention focused less upon individual clinicians than upon pharmaceutical marketers, clinical investigators, the American Medical Association, and the federal government, Finland, Dowling and their supporters would wield the "controlled clinical trial" against the pharmaceutical "testimonial" as a means of ensuring a rational therapeutics. In doing so, they would play an important role in the direction the subsequent Kefauver hearings (1959-1962) would take toward mandating proof of drug efficacy via controlled clinical trials prior to new drug approval. Understanding such a trajectory allows us to better appreciate not only the social history of the controlled clinical trial and the priorities of leaders in infectious disease in the United States during this time, but the consequences of their efforts as well.

    2015-01-01

    This case illustrates the importance of a thorough clinical history in providing an interpretation of previously collected IgE antibody serology as part of a workup for allergic disease. Although a yellow-jacket sting was the allergenic insult that led the patient to the emergency department, nonindicated IgE antibody serology tests were ordered that subsequently required interpretation. This report systematically evaluates the relative significance of previously measured IgE antibody serology responses to 4 major allergen groups (inhalants [aeroallergens], foods, venoms, and drugs) within the context of the patient's history. An algorithm that takes into account the pretest likelihood of disease and diagnostic sensitivity and specificity of the available IgE antibody tests is proposed for decisions about further IgE testing. This case study concludes that selection of testing methods, extract and molecular allergen specificities, and the final interpretation of the results from tests of sensitization such as serological (in vitro) IgE antibody assays requires knowledge of test parameters and clinical judgments based largely on a carefully collected clinical history and physical examination.

    Full Text Available Background: Infertility is a common gynaecological problem and male factor contributes significantly in the aetiology of infertility. Semen analysis has remained a useful investigation in the search for male factor infertility. Aim: This study assessed the pattern of semen parameters and predictive factors associated with abnormal parameters in male partners of infertile couples attending a Nigerian tertiary hospital. Methods: A descriptive study of infertile couples presenting at the clinic between January 2012and December 2015 was done at Ekiti State University Teaching Hospital, Ado-Ekiti. Seminal fluid from the male partners were analysed in the laboratory using the WHO 2010 criteria for human semen characteristics. Data was analysed using SPSS 17 and logistic regression analysis was used to determine the predictive factors associated with abnormal semen parameters. Results: A total of 443 men participated in the study and 38.2% had abnormal sperm parameters. Oligozoospermia (34.8% and asthenozoospermia (26.9% are leading single factor abnormality found, astheno-oligozoospermia occurred in 14.2% and oligo-astheno-teratozoospermia in 3.6% of cases. The prevalence of azoospermia was 3.4%. Smoking habit, past infection with mumps and previous groin surgery significantly predicted abnormal semen parameters with p values of 0.025, 0.040 and 0.017 respectively. Positive cultures were recorded in 36.2% of cases and staph aureus was the commonest organism. Conclusion: Male factor abnormalities remain significant contributors to infertility and men should be encouraged through advocacy to participate in investigation of infertility to reduce the level of stigmatization and ostracizing of women with infertility especially in sub-Saharan Africa.

  16. Abnormal Uterine Bleeding: American College of Nurse-Midwives.

    Science.gov (United States)

    2016-07-01

    Variations in uterine bleeding, termed abnormal uterine bleeding, occur commonly among women and often are physiologic in nature with no significant consequences. However, abnormal uterine bleeding can cause significant distress to women or may signify an underlying pathologic condition. Most women experience variations in menstrual and perimenstrual bleeding in their lifetimes; therefore, the ability of the midwife to differentiate between normal and abnormal bleeding is a key diagnostic skill. A comprehensive history and use of the PALM-COEIN classification system will provide clear guidelines for clinical management, evidence-based treatment, and an individualized plan of care. The purpose of this Clinical Bulletin is to define and describe classifications of abnormal uterine bleeding, review updated terminology, and identify methods of assessment and treatment using a woman-centered approach.

    Full Text Available BACKGROUND AND OBJECTIVES Abnormal Uterine Bleeding (AUB is a very frequent gynaecological complaint and occurs across the entire age spectrum, approximately 75000 hysterectomies are carried out each year with 30% of these for menstrual problems alone. These menstrual aberrations occur more commonly at extremes of reproductive life. The introduction of hysteroscopy has opened a new dimension in evaluation of patient with AUB replacing the blind technique of Dilatation and Curettage. The present study was undertaken to know the accuracy of various tests with Histopathology. MATERIALS AND METHODS The present prospective study was carried out on 100 patients from reproductive, perimenopausal and postmenopausal age group with abnormal uterine bleeding in Dr. B. R. Ambedkar Medical College and Hospital. RESULTS In the present study, in relation to histopathological examination, clinical findings and hysteroscopy had better accuracy (72% as compared to ultrasound findings (41% in diagnosis of abnormal uterine bleeding. CONCLUSION Hysteroscopy guided biopsy and histopathology complements each other in the evaluation of patient with abnormal uterine bleeding for accurate diagnosis and further treatment.

    Full Text Available Introduction: Strategies to identify high-risk emergency department (ED patients often use markedly abnormal vital signs and serum lactate levels. Risk stratifying such patients without using the presence of shock is challenging. The objective of the study is to identify independent predictors of in-hospital adverse outcomes in ED patients with abnormal vital signs or lactate levels, but who are not in shock. Methods: We performed a prospective observational study of patients with abnormal vital signs or lactate level defined as heart rate ≥130 beats/min, respiratory rate ≥24 breaths/min, shock index ≥1, systolic blood pressure 4.0mmol/L (OR 5.1, 95% CI [2.1–12.2], age ≥80 yrs (OR 1.9, CI [1.0–3.7], bicarbonate <21mEq/L (OR 2.5, CI [1.3–4.9], and initial HR≥130 (OR 3.1, CI [1.5–6.1]. Conclusion: Patients exhibiting abnormal vital signs or elevated lactate levels without shock had significant rates of deterioration after hospitalization. ED clinical data predicted patients who suffered adverse outcomes with reasonable reliability.

    Pitt-Hopkins syndrome is a rare genetic form of severe psychomotor delay, caused by mutations in transcription cell factor-4 gene and characterized by distinctive dysmorphic features and abnormal breathing pattern. The current report describes the polygraphic features of the syndrome's typical breathing pattern in a patient both in wakefulness and in sleep. The control of these breathing alterations is important to prevent the neurological sequelae linked to chronic cerebral hypoxemia in early ages. No data are available on effective treatment options for breathing abnormalities of Pitt-Hopkins syndrome. The authors polygraphically documented a reduction of apneic and hypopneic phenomena, with a significant improvement in saturation values, after the introduction of sodium valproate.

    Computed tomography is currently the method of choice for the diagnostic and staging of lymphomas. Computed tomography enables accurate measurements of both tumor extent and volume and provides information that can be used to plan an appropriate strategy for the treatment. The purpose of the present article is to describe and analyze the chest and abdomen computed tomography and ultrasound findings in HIV-negative patients with lymphoma. Clinical abnormalities, such as the reason the patient sought medical assistance already showing evidence of lymphocytic disease (not yet diagnosed at this point) and the physical examination abnormalities seen on the first consultation were also studied. This study comprised 30 patients: 40% with non-Hodgkin lymphoma, 46,6% with Hodgkin lymphoma, 10% with Burkitt's lymphoma and 3,3% with lymphoblastic lymphoma. (author)

    Full Text Available Abstract Background Among the psychological difficulties seen in children of parents with substance use problems, the anxiety disorders are among the most chronic conditions. Although children of alcoholic parents often struggle with the effects of parental substance use problems long into adulthood, empirical investigations of the influence of parental substance use disorders on the course of anxiety disorders in adult offspring are rare. The purpose of this study was to examine prospectively the relationship between parental substance use disorders and the course of anxiety disorders in adulthood over the course of 12 years. Methods Data on 618 subjects were derived from the Harvard/Brown Anxiety Research Project (HARP, a longitudinal naturalistic investigation of the clinical course of multiple anxiety disorders. Kaplan-Meier survival estimates were used to calculate probabilities of time to anxiety disorder remission and relapse. Proportional hazards regressions were conducted to determine whether the likelihood of remission and relapse for specific anxiety disorders was lower for those who had a history of parental substance use disorders than for individuals without this parental history. Results Adults with a history of parental substance use disorders were significantly more likely to be divorced and to have a high school level of education. History of parental substance use disorder was a significant predictor of relapse of social phobia and panic disorders. Conclusion These findings provide compelling evidence that adult children of parents with substance use disorders are more likely to have relapses of social phobia and panic disorders. Clinicians who treat adults with anxiety disorders should assess parental substance use disorders and dependence histories. Such information may facilitate treatment planning with regards to their patients' level of vulnerability to perceive scrutiny by others in social situations, and ability to

    Hair shaft disorders may lead to brittleness and uncombable hair. In general the hair feels dry and lusterless. Hair shaft abnormalities may occur as localized or generalized disorders. Genetic predisposition or exogenous factors are able to produce and maintain hair shaft abnormalities. In addition to an extensive history and physical examination the most important diagnostic examination to analyze a hair shaft problem is light microscopy. Therapy of hair shaft disorders should focus to the cause. In addition, minimizing traumatic influences to hair shafts, such as dry hair with an electric dryer, permanent waves and dyes is important. A short hair style is more suitable for such patients with hair shaft disorders.

    Highlights: • Abnormal {sup 18}F-FDG uptakes in the head and neck (HN) region can be carefully interpreted as being index primary, second primary cancer (SP) or benign. • {sup 18}F-FDG PET/CT identified 91.9% primary HN squamous cell carcinomas (HNSCC). • The specificity and negative predictive value of {sup 18}F-FDG PET/CT for identification of SP were as high as 98.7% and 99.3%, respectively. • Proper detection of primary tumors and SP in the HN region may promote appropriate therapeutic planning of HNSCC patients. - Abstract: Purpose: Fluorine 18-fluorodeoxyglucose ({sup 18}F-FDG) positron emission tomography (PET)/computed tomography (CT) is used to identify index or second primary cancer (SP) of the head and neck (HN) through changes in {sup 18}F-FDG uptake. However, both physiologic and abnormal lesions increase {sup 18}F-FDG uptake. Therefore, we evaluated {sup 18}F-FDG uptake in the HN region to determine clinical values of abnormal tracer uptake. Methods: A prospective study approved by the institutional review board was conducted in 314 patients with newly diagnosed HN squamous cell carcinoma (HNSCC) and informed consent was obtained from all enrolled patients. The patients received initial staging workups including {sup 18}F-FDG PET/CT and biopsies. All lesions with abnormal HN {sup 18}F-FDG uptake were recorded and most of those were confirmed by biopsies. Diagnostic values for abnormal {sup 18}F-FDG uptake were calculated. Results: Abnormal {sup 18}F-FDG uptake was identified in primary tumors from 285 (91.9%) patients. False-negative results were obtained for 22.3% (23/103) T1 tumors and 2.2% (2/93) T2 tumors (P < 0.001). Thirty-eight regions of abnormal {sup 18}F-FDG uptake were identified in 36 (11.5%) patients: the thyroid (n = 13), maxillary sinus (n = 7), palatine tonsil (n = 6), nasopharynx (n = 5), parotid gland (n = 2) and others (n = 5). Synchronous SP of the HN was identified in eight (2.5%) patients: the thyroid (n = 5), palatine

    We aimed to perform a comprehensive systematic review of the existing ataxia scales. We described the disorders for which the instruments have been validated and used, the time spent in its application, its validated psychometric properties, and their use in studies of natural history and clinical trials. A search from 1997 onwards was performed in the MEDLINE, LILACS, and Cochrane databases. The web sites ClinicalTrials.gov and Orpha.net were also used to identify the endpoints used in ongoing randomized clinical trials. We identified and described the semiquantitative ataxia scales (ICARS, SARA, MICARS, BARS); semiquantitative ataxia and non-ataxia scales (UMSARS, FARS, NESSCA); a semiquantitative non-ataxia scale (INAS); quantitative ataxia scales (CATSYS 2000, AFCS, CCFS and CCFSw, and SCAFI); and the self-performed ataxia scale (FAIS). SARA and ICARS were the best studied and validated so far, and their reliability sustain their use. Ataxia and non-ataxia scores will probably provide a better view of the overall disability in long-term trials and studies of natural history. Up to now, no clear advantage has been disclosed for any of them; however, we recommend the use of specific measurements of gait since gait ataxia is the first significant manifestation in the majority of ataxia disorders and comment on the best scales to be used in specific ataxia forms. Quantitative ataxia scales will be needed to speed up evidence from phase II clinical trials, from trials focused on the early phase of diseases, and for secondary endpoints in phase III trials. Finally, it is worth remembering that estimation of the actual minimal clinically relevant difference is still lacking; this, together with changes in quality of life, will probably be the main endpoints to measure in future therapeutic studies.

    Recording medical histories of patients is not a new issue in clinical medicine. However, the method practiced by the Iranian chemist physician, Rhazes, in the ninth century A.D is incredible. Rhazes has written several textbooks in clinical medicine, but a particular one, "Clinical Stories and Medical Histories" (Qesas va hekayat al-marazi), is a classical case book describing precise clinical courses of thirty three patients. Each chapter includes a title, the name and demographic data about a patient, his/her history of present illness, past medical and family history, findings of physical exam, impression and interventions by the physician, including pharmacological or surgical management. The reasons for each decision made by Rhazes as well as the outcomes are clearly discussed. This book review will shed light on the unknown medical practice methods in Islamic-Iranian golden era.

    The history of assessing the acid–base equilibrium and associated disorders is intertwined with the evolution of the definition of an acid. In the 1950s clinical chemists combined the Henderson–Hasselbalch equation and the Bronsted–Lowry definition of an acid to produce the current bicarbonate ion-centred approach to metabolic acid–base disorders. Stewart repackaged pre-1950 ideas of acid–base in the late 1970s, including the Van Slyke definition of an acid. Stewart also used laws of physical...

    Full Text Available The evolution of clinical research traverses a long and fascinating journey. From the first recorded trial of legumes in biblical times to the first randomized controlled of trial of streptomycin in 1946, the history of clinical trial covers a wide variety of challenges - scientific, ethical and regulatory. The famous 1747 scurvy trial conducted by James Lind contained most elements of a controlled trial. The UK Medical Research Council′s (MRC trial of patulin for common cold in 1943 was the first double blind controlled trial. This paved the way for the first randomized control trial of streptomycin in pulmonary tuberculosis carried out in 1946 by MRC of the UK. This landmark trial was a model of meticulousness in design and implementation, with systematic enrolment criteria and data collection compared with the ad hoc nature of other contemporary research. Over the years, as the discipline of controlled trials grew in sophistication and influence, the streptomycin trial continues to be referred to as ground breaking. The ethical advances in human protection include several milestones - Nuremberg Code, Declaration of Helsinki, Belmont Report, and 1996, International Conference on Harmonization Good Clinical Practice guidance. In parallel to ethical guidelines, clinical trials started to become embodied in regulation as government authorities began recognizing a need for controlling medical therapies in the early 20th century. As the scientific advances continue to occur, there will be new ethical and regulatory challenges requiring dynamic updates in ethical and legal framework of clinical trials.

    Hiroko Hagiwara

    Full Text Available BACKGROUND: D-Serine, an endogenous co-agonist of the N-methyl-D-aspartate (NMDA receptor, is synthesized from L-serine by serine racemase (SRR. Given the role of D-serine in both neurodevelopment and the pathophysiology of schizophrenia, we examined whether neonatal disruption of D-serine synthesis by SRR inhibition could induce behavioral abnormalities relevant to schizophrenia, in later life. METHODOLOGY/PRINCIPAL FINDINGS: Neonatal mice (7-9 days were injected with vehicle or phenazine methosulfate (Met-Phen: 3 mg/kg/day, an SRR inhibitor. Behavioral evaluations, such as spontaneous locomotion, novel object recognition test (NORT, and prepulse inhibition (PPI were performed at juvenile (5-6 weeks old and adult (10-12 weeks old stages. In addition, we tested the effects of D-serine on PPI deficits in adult mice after neonatal Met-Phen exposure. Finally, we assessed whether D-serine could prevent the onset of schizophrenia-like behavior in these mice. Neonatal Met-Phen treatment reduced D-serine levels in the brain, 24 hours after the final dose. Additionally, this treatment caused behavioral abnormalities relevant to prodromal symptoms in juveniles and to schizophrenia in adults. A single dose of D-serine improved PPI deficits in adult mice. Interestingly, chronic administration of D-serine (900 mg/kg/day from P35 to P70 significantly prevented the onset of PPI deficits after neonatal Met-Phen exposure. CONCLUSIONS/SIGNIFICANCE: This study shows that disruption of D-serine synthesis during developmental stages leads to behavioral abnormalities relevant to prodromal symptoms and schizophrenia, in later life. Furthermore, early pharmacological intervention with D-serine may prevent the onset of psychosis in adult.

    Full Text Available Background: Suicidal behavior is a critical problem among military veterans. Therefore, it is important to identify psychological suicide risk factors that are unique for veterans of military service. We compared clinical features of 55 veteran suicide attempters with 55 veterans without a history of suicide attempts. Methods: Demographic and clinical characteristics of suicide attempters and non-attempters were assessed and recorded. Based on the Scale for Suicide Ideation (SSI all patients were divided into two groups: patients who do not report any suicidal ideation at all (non-ideators and people who do (ideators. Results: There was no difference between the groups with regard to age (t= − 0.71, df = 108, p=0.48, gender (χ2=1.50, df = 1, p=0.36, and race (χ2=4.84, df = 5, p=0.44. There were more subjects with a lifetime history of bipolar disorder, substance dependence, or psychotic disorder among suicide attempters compared to non-attempters (χ2=6.67, df = 1, p=0.01, χ2=4.71, df = 1, p=0.04, and χ2=9.83, df = 1, p = 0.002, respectively. There were 34% of current suicide ideators among suicide attempters and 9.3% of suicide ideators among non-attempters (χ2=9.67, df = 1, p=0.002. There was no difference with regard to the proportion of patients with major depression or posttraumatic stress disorder between suicide attempters and non-attempters (χ2=0.10, df = 1, p=0.83 and χ2=0.41, df = 1, p=0.54, respectively. Conclusion: A history of suicide attempt in military veterans is associated with a lifetime history of bipolar disorder, substance dependence, psychotic disorder, or current suicidal ideation but not with a lifetime history of major depression or posttraumatic stress disorder.

    Full Text Available The objective of the present study was to evaluate the reliability and clinical utility of a Portuguese version of the Abnormal Involuntary Movements Scale (AIMS. Videotaped interviews with 16 psychiatric inpatients treated with antipsychotic drugs for at least 5 years were evaluated. Reliability was assessed by the intraclass correlation coefficient (ICC between three raters, two with and one without clinical training in psychopathology. Clinical utility was assessed by the difference between the scores of patients with (N = 11 and without (N = 5 tardive dyskinesia (TD. Patients with TD exhibited a higher severity of global evaluation by the AIMS (sum of scores: 4.2 ± 0.9 vs 0.4 ± 0.2; score on item 8: 2.3 ± 0.3 vs 0.4 ± 0.2, TD vs controls. The ICC for the global evaluation was fair between the two skilled raters (0.58-0.62 and poor between these raters and the rater without clinical experience (0.05-0.29. Thus, we concluded that the Portuguese version of the AIMS shows an acceptable inter-rater reliability, but only between clinically skilled raters, and that it is clinically useful.

    The Cancer Genome Atlas Network recently cataloged recurrent genomic abnormalities in glioblastoma multiforme (GBM). We describe a robust gene expression-based molecular classification of GBM into Proneural, Neural, Classical, and Mesenchymal subtypes and integrate multidimensional genomic data to establish patterns of somatic mutations and DNA copy number. Aberrations and gene expression of EGFR, NF1, and PDGFRA/IDH1 each define the Classical, Mesenchymal, and Proneural subtypes, respectively. Gene signatures of normal brain cell types show a strong relationship between subtypes and different neural lineages. Additionally, response to aggressive therapy differs by subtype, with the greatest benefit in the Classical subtype and no benefit in the Proneural subtype. We provide a framework that unifies transcriptomic and genomic dimensions for GBM molecular stratification with important implications for future studies.

    Drug-induced liver chemistry abnormalities, primarily transaminase elevations, are commonly observed in pazopanib-treated patients. This meta-analysis characterises liver chemistry abnormalities associated with pazopanib. Data of pazopanib-treated patients from nine prospective trials were integrated (N=2080). Laboratory datasets were used to characterise the incidence, timing, recovery and patterns of liver events, and subsequent rechallenge with pazopanib. Severe cases of liver chemistry abnormalities were clinically reviewed. Multivariate analyses identified predisposing factors. Twenty percent of patients developed elevated alanine aminotransferase (ALT) >3×ULN. Incidence of peak ALT >3-5×ULN, >5-8×ULN, >8-20×ULN and >20×ULN was 8%, 5%, 5% and 1%, respectively. Median time to onset for all events was 42days; 91% of events were observed within 18weeks. Recovery rates based on peak ALT >3-5×ULN, >5-8×ULN, >8-20×ULN and >20×ULN were 91%, 90%, 90% and 64%, respectively. Median time from onset to recovery was 30days, but longer in patients without dose interruption. Based on clinical review, no deaths were associated with drug-induced liver injury. Overall, 38% of rechallenged patients had ALT elevation recurrence, with 9-day median time to recurrence. Multivariate analysis showed that older age was associated with development of ALT >8×ULN. There was no correlation between hypertension and transaminitis. Our data support the current guidelines on regular liver chemistry tests after initiation of pazopanib, especially during the first 9 or 10weeks, and also demonstrate the safety of rechallenge with pazopanib.

    Lack of clinical history on radiology requisitions is a universal problem. We describe a simple Web-based system that readily provides radiology-relevant clinical history to the radiologist reading radiographs of intensive care unit (ICU) patients. Along with the relevant history, which includes primary and secondary diagnoses, disease progression and complications, the system provides the patient's name, record number and hospital location. This information is immediately available to reporting radiologists. New clinical information is immediately entered on-line by the radiologists as they are reviewing images. After patient discharge, the data are stored and immediately available if the patient is readmitted. The system has been in routine clinical use in our hospital for nearly 2 years. (orig.)

    Full Text Available The 2001 Bethesda system recommends further classifying atypical glandular cells (AGCs as either endocervical or endometrial origin. Numerous studies have investigated the clinical significance of AGC. In this study, we investigated the incidence of clinically significant lesions among women with liquid-based Papanicolaou cervicovaginal (Pap interpretations of atypical endometrial cells (AEMs or AGC favor endometrial origin (AGC-EM. More importantly, we correlated patients of AEM or AGC-EM with their clinical presentations to determine if AEM/AGC-EM combined with abnormal vaginal bleeding is associated with a higher incidence of significant endometrial pathology. All liquid-based Pap tests with an interpretation of AEM and AGC-EM from July, 2004 through June, 2009 were retrieved from the database. Women with an interpretation of atypical endocervical cells, AGC, favor endocervical origin or AGC, favor neoplastic were not included in the study. The most severe subsequent histologic diagnoses were recorded for each patient. During this 5-year period, we accessioned 332,470 Pap tests of which 169 (0.05% were interpreted as either AEM or AGC-EM. Of the 169 patients, 133 had histologic follow-up within the health care system. The patients ranged in age from 21 to 71 years old (mean 49.7. On follow-up histology, 27 (20.3% had neoplastic/preneoplastic uterine lesions. Among them, 20 patients were diagnosed with adenocarcinoma (18 endometrial, 1 endocervical, and 1 metastatic colorectal, 3 with atypical endometrial hyperplasia, and 4 with endometrial hyperplasia without atypia. All patients with significant endometrial pathology, except one, were over 40 years old, and 22 of 25 patients reported abnormal vaginal bleeding at the time of endometrial biopsy or curettage. This study represents a large series of women with liquid-based Pap test interpretations of AEM and AGC-EM with clinical follow-up. Significant preneoplastic or neoplastic endometrial

    Full Text Available OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males. ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42% and dilated cardiomyopathy (19%. Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

    This review attempts to assemble the characteristics of a distinct variant of sleepwalking called sexsomnia/sleepsex from the seemingly scarce literature into a coherent theoretical framework. Common features of sexsomnia include sexual arousal with autonomic activation (e.g. nocturnal erection, vaginal lubrication, nocturnal emission, dream orgasms). Somnambulistic sexual behavior and its clinical implications, the role of precipitating factors, diagnostic, treatment, and medico-legal issues are also reviewed. The characteristics of several individuals described in literature including their family/personal history of parasomnia as well as the abnormal behaviors occurring during sleep are reported.

    The aim of the study is to determine the inter-reliability and intra-observer reliability of magnetic resonance imaging (MRI) for lateral epicondylitis and investigate whether there is a potential relationship between MRI abnormalities of the common extensor tendon (CET) and its clinical symptom.The study group comprised 96 consecutive patients (46 men and 50 women) with a clinical diagnosis of chronic lateral epicondylitis, which were examined on 3.0 T MR. An MRI scoring system was used to grade the degree of tendinopahty. Three independent musculoskeletal radiologists, who were blinded to the patients' clinical information, scored images separately. Clinical symptoms were assessed using the Patient-Rated Tennis Elbow Evaluation (PRTEE).Of all the patients, total 96 elbows had MRI-assessed tendinopathy, including 38 (39.6%) with grade 1, 31 (32.3%) with grade 2, and 27 (28.1%) with grade 3. Inter-observer reliability and intra-observer agreement for MRI interpretation of the grades of tendinopathy was good, and a positive correlation between the grades of tendinopathy and PRTEE was determined.MRI is a reliable tool in determining radiological severity of chronical lateral epicondylitis. The severity of MR signal changes positively correlate with the patient's clinical symptom.

    In recent years, the National Academy of Neuropsychology and other professional neuropsychological organizations have published a number of articles and position papers regarding the use, education, and training of psychometrists ("technicians"). Although these documents provide guidelines for the suggested qualifications and training procedures of psychometrists, none make any mention of the need for a standardized credentialing process, which is commonly required of technicians in similar fields, especially in medical settings. Given the recent changes in current procedural Terminology codes used to bill for neuropsychological services and the interpretation of legislation disallowing the use of psychometrists in New York, the need for a standard credential for psychometrists is apparent. This article will review the history and current use of psychometrists in clinical neuropsychology and highlight the need and rationale for the credentialing of psychometrists.

    A phase abnormality in radionuclide multigated studies (MUGA) in patients with tricuspid regurge (TR) is being described. In this condition of TR, as the right ventricle contracts, if causes the blood to regurge through the tricuspid valve to the right atrium and through the inferior Vena cava and hepatic veins to the adjacent liver tissue. As a result the right atrium and the liver will be in the same delayed phase forming a Crescent to the right side of the heart representing the right atrium and extending below the heart into the region of the liver. This Crescent has been graded according to how far it is extending in the liver and below the heart. In 15 patients with cardiac cath finding of TR (done within 2-3 days of the MUGA study), the phase displays of the radionuclide MUGA studies were analysed in order to find out the sensitivity of the Crescent Sign in the detection of TR and whether there is a relationship between the grade of the Crescent and the severity of the regurgitation. The Crescent was found in 13 of the 15 patients (sensitivity = 87%). We have not found a correlation between the severity of TR and the grade of the Crescent. We conclude that the presence of the Crescent Sign in phase display of the MUGA study should direct the attention of the clinician towards the recognition of TR, a condition which is sometimes difficult to diagnose non-invasively.

    2016-05-01

    The clinical evaluation of patients with tinnitus differs based on whether the tinnitus is subjective or objective. Subjective tinnitus is usually associated with a hearing loss, and therefore, the clinical evaluation is focused on an otologic and audiologic evaluation with adjunct imaging/tests as necessary. Objective tinnitus is divided into perception of an abnormal somatosound or abnormal perception of a normal somatosound. The distinction between these categories is usually possible based on a history, physical examination, and audiogram, leading to directed imaging to identify the underlying abnormality.

    Conclusion: In patients with DM1, the combined smaller overall gray matter volume and white matter alterations seem to be the main morpho-structural substrates of CNS involvement in this condition. The correlation of white matter differences with both clinical and genetic findings lends support to this notion.

    The aim of this study was to evaluate the long-term clinical significance of an additional chromosomal abnormality (ACA), variant Philadelphia chromosome (vPh) at diagnosis, and newly developed other chromosomal abnormalities (OCA) in patients with chronic myeloid leukemia (CML) on imatinib (IM) therapy. Sequential cytogenetic data from 281 consecutive new chronic phase CML patients were analyzed. With a median follow-up of 78.6 months, the 22 patients with vPh (P = 0.034) or ACA (P = 0.034) at diagnosis had more events of IM failure than did the patients with a standard Ph. The 5-year overall survival (OS), event-free survival (EFS), and failure-free survival (FFS) rates for patients with vPh at diagnosis were 77.8%, 75.0%, and 53.3%, respectively; for patients with ACA at diagnosis, 100%, 66.3%, and 52.1%, respectively; and for patients with a standard Ph, 96.0%, 91.3%, and 83.7%, respectively. During IM therapy, eight patients developed an OCA, which had no impact on outcomes as a time-dependent covariate in our Cox proportional hazards regression models. This study showed that vPh was associated with poor OS and FFS and that ACA had adverse effects on EFS and FFS. In addition, no OCA, except monosomy 7, had any prognostic impact, suggesting that the development of OCA may not require a change in treatment strategy.

    Full Text Available Abstract Background A lot of studies have showed an excess maternal transmission of type 2 diabetes (T2D. The aim, therefore, of the present study was to estimate the prevalence of familial history of T2D in Greek patients, and to evaluate its potential effect on the patient's metabolic control and the presence of diabetic complications. Methods A total of 1,473 T2D patients were recruited. Those with diabetic mothers, diabetic fathers, diabetic relatives other than parents and no known diabetic relatives, were considered separately. Results The prevalence of diabetes in the mother, the father and relatives other than parents, was 27.7, 11.0 and 10.7%, respectively. Patients with paternal diabetes had a higher prevalence of hypertension (64.8 vs. 57.1%, P = 0.05 and lower LDL-cholesterol levels (115.12 ± 39.76 vs. 127.13 ± 46.53 mg/dl, P = 0.006 than patients with diabetes in the mother. Patients with familial diabetes were significantly younger (P 2, P = 0.08, higher prevalence of dyslipidemia (49.8 vs. 44.6%, P = 0.06 and retinopathy (17.9 vs. 14.5%, P = 0.08 compared with patients with no diabetic relatives. No difference in the degree of metabolic control and the prevalence of chronic complications were observed. Conclusion The present study showed an excess maternal transmission of T2D in a sample of Greek diabetic patients. However, no different influence was found between maternal and paternal diabetes on the clinical characteristics of diabetic patients except for LDL-cholesterol levels and presence of hypertension. The presence of a family history of diabetes resulted to an early onset of the disease to the offspring.

  14. Schizophrenia, abnormal connection, and brain evolution.

    Science.gov (United States)

    Randall, P L

    1983-03-01

    Abnormalities of functional connection between specialized areas in the human brain may underlie the symptoms which constitute the schizophrenia syndrome. Callosal and intrahemispheric fibres may be equally involved. The clinical emergence of symptoms in the later stages of brain maturation may be dependent on myelination of these fibre groups, both of which have extended myelination cycles. Ontogenetically earlier variants of the same mechanism could theoretically result in dyslexia and the syndromes of Kanner and Gilles de la Tourette. As new and unique extensions of specialized function emerge within the evolving brain, biological trial and error of connection both within and between them may produce individuals possessing phylogenetically advanced abilities, or equally, others possessing a wide range of abnormalities including those which comprise the schizophrenia syndrome. A dormant phenotypic potential for schizophrenia may exist in individuals who never develop symptoms during the course of a lifetime though some of these may become clinically apparent under the influence of various precipitating factors. It is concluded that abnormal functional connection and its normal and "supernormal" counterparts may be natural, essential, and inevitable consequences of brain evolution, and that this may have been so throughout the history of vertebrate brain evolution.

  15. Abnormalities of gonadal differentiation.

    Berkovitz, G D; Seeherunvong, T

    1998-04-01

    Gonadal differentiation involves a complex interplay of developmental pathways. The sex determining region Y (SRY) gene plays a key role in testis determination, but its interaction with other genes is less well understood. Abnormalities of gonadal differentiation result in a range of clinical problems. 46,XY complete gonadal dysgenesis is defined by an absence of testis determination. Subjects have female external genitalia and come to clinical attention because of delayed puberty. Individuals with 46,XY partial gonadal dysgenesis usually present in the newborn period for the valuation of ambiguous genitalia. Gonadal histology always shows an abnormality of seminiferous tubule formation. A diagnosis of 46,XY true hermaphroditism is made if the gonads contain well-formed testicular and ovarian elements. Despite the pivotal role of the SRY gene in testis development, mutations of SRY are unusual in subjects with a 46,XY karyotype and abnormal gonadal development. 46,XX maleness is defined by testis determination in an individual with a 46,XX karyotype. Most affected individuals have a phenotype similar to that of Klinefelter syndrome. In contrast, subjects with 46,XX true hermaphroditism usually present with ambiguous genitalia. The majority of subjects with 46,XX maleness have Y sequences including SRY in genomic DNA. However, only rare subjects with 46,XX true hermaphroditism have translocated sequences encoding SRY. Mosaicism and chimaerism involving the Y chromosome can also be associated with abnormal gonadal development. However, the vast majority of subjects with 45,X/46,XY mosaicism have normal testes and normal male external genitalia.

    Full Text Available Introduction: Psoriasis is a chronic inflammatory skin disease that affects about 2% of general population. Cllinicaly, disease can present with cutaneous and nails lesions. Nail abnormalities can be seen in up to two-thirds of patients with psoriasis and both fingernails and toenails may be affected.Objective: The objectives of our study were to evaluate the frequency and clinical presentations of nail abnormalities in patients with psoriasis. Also, we aimed to find correlation between nail changes and some clinical parameters.Methods: One hundred and ten patients with psoriasis were included in this study. A detailed history and examination was recorded for all study subjects, including the age and gender of the patients, type of psoriasis, duration, and extent of disease. Finger and toe nails were clinically examined and nail changes were noted. In the case of clinicaly suspected of fungal infection, further mycological investigations were performed.Results: Nail abnormalities were present in 67 patients (60.9% with psoriasis. Nail pitting was the most common lesion observed on fingernails, followed by discoloration of nail plate. Subungual hyperkeratosis of nail plates were significantly more frequent on the toenails. Positive mycological culture was in 14 (20.8% psoriatic patients with nail involvement. Also, positive correlation between nail abnormalities and duration of psoriasis was found.Conclusions: Nail involvement is common in patients with psoriasis and accompanies skin lesions on the body surface. Pitting and subungual hyperkeratosis are the most frequent nail abnormality in psoriatic patients.

    This study examined the association between recent trends in CD4 and viral loads and cognitive test performance with the expectation that recent history could predict cognitive performance. Eighty-three human immunodeficiency virus (HIV)-infected patients with a mean CD4 count of 428 copies/ml were examined in this study (62% with undetectable plasma viral load [PVL]). We investigated the relationships between nadir CD4 cell count, 1-year trends in immunologic function/PVLs, and cognitive performance across several domains using linear regression models. Nadir CD4 cell count was predictive of current executive function (p = .004). One year clinical history for CD4 cell counts and/or PVLs were predictive of executive function, attention/working memory, and learning/memory measures (p < .05). Models that combined recent clinical history trends and nadir CD4 cell counts suggested that recent clinical trends were more important in predicting current cognitive performance for all domains except executive function. This research suggests that recent CD4 and viral load history is an important predictor of current cognitive function across several cognitive domains. If validated, clinical variables and cognitive dysfunction models may improve our understanding of the dynamic relationships between disease evolution and progression and CNS involvement.

    Objective This study examined whether having a history of anorexia nervosa (AN) or bulimia nervosa (BN) is associated with response to treatment in adults with binge eating disorder (BED). Method Data from 189 adults diagnosed with BED who were randomly assigned to one of three group cognitive-behavioral (CBT) treatments were analyzed to compare those with and without a history of AN/BN. Results A total of 16% of the sample had a history of AN/BN. The BED subgroup with a history of AN/BN presented with higher rates of mood disorders and greater eating-related symptom severity at baseline. Participants with a history of AN/BN also had higher global eating disorder (ED) symptoms at end of treatment (EOT), and more frequent objective binge-eating episodes at EOT and 12-month follow-up. Discussion These findings suggest that in adults with BED, a history of AN/BN is predictive of greater eating-related symptom severity following group-based CBT and poorer short- and long-term binge-eating outcomes. These findings suggest that considering ED history in the treatment of adults with BED may be clinically useful. PMID:25959549

    The aim of this study was to investigate the influence of the Multiwave Locked System (MLS) laser therapy on clinical features, microvascular changes in nailfold videocapillaroscopy (NVC) and circulating modulators releasing as a consequence of vascular endothelium injury such as vascular endothelial growth factor (VEGF) and angiopoietin 2 (Ang-2) in patients with primary and secondary Raynaud's phenomenon. Seventy-eight RP patients and 30 healthy volunteers were recruited into the study. All patients with RP received MLS laser irradiation for 3 weeks. Clinical, NVC and laboratory investigations were performed before and after the MLS laser therapy. The serum concentration of VEGF and Ang-2 were determined by an enzyme-linked immunosorbent assay (ELISA). After 3 weeks of MLS laser therapy, the clinical improvement manifested by decreasing of the number of RP attacks, mean duration of Raynaud's attack and pain intensity in RP patients was observed. After MLS laser therapy in 65% of patients with primary and in 35% with secondary RP, an increase in the loop number and/or a reduction in avascular areas in NVC were observed. In comparison with a control group, higher serum concentration of VEGF and Ang-2 in RP patients was demonstrated. After MLS laser therapy, a reduction of Ang-2 in both groups of RP patients was found. Our results suggest that NVC may reflect microvascular changes associated with clinical improvement after MLS laser therapy in patients with primary and secondary RP. Ang-2 serum levels may be a useful marker of microvascular abnormalities in RP patients treated with MLS laser therapy.

  2. Abnormal pressure in hydrocarbon environments

    Law, B.E.; Spencer, C.W.

    1998-01-01

    Abnormal pressures, pressures above or below hydrostatic pressures, occur on all continents in a wide range of geological conditions. According to a survey of published literature on abnormal pressures, compaction disequilibrium and hydrocarbon generation are the two most commonly cited causes of abnormally high pressure in petroleum provinces. In young (Tertiary) deltaic sequences, compaction disequilibrium is the dominant cause of abnormal pressure. In older (pre-Tertiary) lithified rocks, hydrocarbon generation, aquathermal expansion, and tectonics are most often cited as the causes of abnormal pressure. The association of abnormal pressures with hydrocarbon accumulations is statistically significant. Within abnormally pressured reservoirs, empirical evidence indicates that the bulk of economically recoverable oil and gas occurs in reservoirs with pressure gradients less than 0.75 psi/ft (17.4 kPa/m) and there is very little production potential from reservoirs that exceed 0.85 psi/ft (19.6 kPa/m). Abnormally pressured rocks are also commonly associated with unconventional gas accumulations where the pressuring phase is gas of either a thermal or microbial origin. In underpressured, thermally mature rocks, the affected reservoirs have most often experienced a significant cooling history and probably evolved from an originally overpressured system.

    Objective: Angiogennesis, the formation of new blood vessels from the existing vascular bed, is essential step for growth and invasion of primary tumor. Vascular endothelial growth-factor (VEGF) is known to play crucial role in tumor angiogenesis. In the present study, we investigate the expression of VEGF and VEGF-mRNA in the angiogennesis, metastasis and prognosis of lung cancer.Methods: The VEGF cellular distributions and expression in 38 specimens of patients with lung cancer were investigated with immunohistochemistry stain technology. The total RNAs in 38 tissues of lung cancer was measured, then the levels of VEGF-mRNA expression were analyzed by a reverse-transcription polymerase chain reaction (RT-PCR) assay. The levels of VEGF in sera of patients with lung cancer, benign lung diseases and healthy controls were detected through Enzyme linked immunosorbent assay (ELISA) method. Results: The VEGF positive stain was 76% in 38 cases of lung cancer specimens. The 89% rate of VEGF stain was found for clinical stage Ⅲ cases and 92%for stage Ⅳ lung cancers. The significantly higher expression of VEGF was evidenced in patients with lymph node metastasis (84 % ), distant metastasis (90%), and lung cancers with lower histological differentiation (89%), respectively. The expression level of total RNA was significantly higher in patients with lung cancers than that in their paracancerous or distant lung tissues. The VEGF expressions were tightly correlated with total RNA concentration of lung carcinoma ( P < 0.01 ). The predominant expressions of VEGF121 and VEGF165 gene fragments were found in lung cancer specimens by RT-PCR analysis. No significant difference of serum VEGF levels was detected between cases with lung cancer and patients with benign diseases. However, the VEGF level of cases with benign diseases was decreased significantly after patients with anti-inflammation medication. Conclusion: The present data suggested that the tumor tissue VEGF

    Inherited erythromelalgia, the first human pain syndrome linked to voltage-gated sodium channels, is widely regarded as a genetic model of human pain. Because inherited erythromelalgia was linked to gain-of-function changes of sodium channel Na(v)1.7 only a decade ago, the literature has mainly consisted of reports of genetic and/or clinical characterization of individual patients. This paper describes the pattern of pain, natural history, somatosensory profile, psychosocial status and olfactory testing of 13 subjects with primary inherited erythromelalgia with mutations of SCN9A, the gene encoding Na(v)1.7. Subjects were clinically profiled using questionnaires, quantitative sensory testing and olfaction testing during the in-clinic phase of the study. In addition, a detailed pain phenotype for each subject was obtained over a 3-month period at home using diaries, enabling subjects to self-report pain attacks, potential triggers, duration and severity of pain. All subjects reported pain and heat in the extremities (usually feet and/or hands), with pain attacks triggered by heat or exercise and relieved mainly by non-pharmacological manoeuvres such as cooling. A large proportion of pain attacks (355/1099; 32%) did not involve a specific trigger. There was considerable variability in the number, duration and severity of pain attacks between subjects, even those carrying the same mutation within a family, and within individuals over the 12-13 week observation period. Most subjects (11/13) had pain between attacks. For these subjects, mean pain severity between pain attacks was usually lower than that during an attack. Olfaction testing using the Sniffin'T test did not demonstrate hyperosmia. One subject had evidence of orthostatic hypotension. Overall, there was a statistically significant correlation between total Hospital Anxiety and Depression Scale scores (P= 0.005) and pain between attacks and for Hospital Anxiety and Depression Scale Depression scores and pain

    Full Text Available In the large majority of previous studies, patients with a history of acute urticaria induced by nonsteroidal anti-inflammatory drugs (NSAIDs seeking safe alternative drugs have undergone tolerance tests uniquely with compounds exerting little or no inhibitory effect on the cyclooxygenase 1 enzyme. In light of recently published studies, however, this approach seems inadequate and should be changed. The present article critically reviews the clinical management of patients presenting with a history of urticaria induced by a single NSAID or multiple NSAIDs and suggests a simple, updated diagnostic algorithm that may assist clinicians in correctly classifying their patients.

    Full Text Available Abstract Objective: The abnormalities of the genitourinary tract development are the leading cause of chronic kidney disease (CKD in children. The diagnosis of this disease in Brazil is late and incomplete, which results in increased morbidity and mortality in this age group. Early diagnosis of this condition is the prerogative of generalist pediatricians, and the aim of this study was to review the clinical signs and symptoms associated with developmental abnormalities of the genitourinary tract. Data sources: Based on the description of a symbolic clinical case, the authors conducted a non-systematic review of medical literature. Data synthesis: The results suggest that the following data should be used as a warning for early diagnosis of affected children: (a combined urinary tract abnormalities (chromosomal abnormalities; sequence of malformations [VACTERLand Prune-Belly]; and musculoskeletal, digestive tract, heart, and nervous system malformations; (b previous history (congenital anomalies of the kidney and urinary tract [CAKUT] in the family, low birth weight, and oligoamnios; (c clinical signs (polyuria/nocturia, urinary tract infection, systemic arterial hypertension, failure to thrive, weak urinary stream, difficulty to start urination, distended bladder, non-monosymptomatic enuresis, urinary/urge incontinence, and bowel and bladder dysfunction; and (d pre- and postnatal ultrasonographic alterations (increased anteroposterior diameter of the renal pelvis, mainly in the third trimester of pregnancy; single kidney; hydronephrosis associated with other abnormalities; and hydronephrosis with parenchymal involvement in the post-neonatal assessment. Conclusion: The suggestions shown here can help the pediatrician to establish clinical hypotheses for the early diagnosis of developmental abnormalities of the genitourinary tract without resorting to expensive and invasive procedures.

    The presence of a human tail is a rare and intriguing phenomenon. While cases have been reported in the literature, confusion remains with respect to the proper classification, definition, and treatment methods. We review the literature concerning this anatomical derailment. We also consider the importance of excluding underlying congenital anomalies in these patients to prevent neurological deficits and other abnormal manifestations.

    Penicillin often is excluded as a treatment option based on patients' self-reported history of an adverse reaction to penicillin. The objective of this prospective study was to determine the likelihood of true penicillin allergy in patients with vague and convincing histories of penicillin allergy and to evaluate the diagnostic value added by appropriate skin testing. Six hundred thirty-eight patients with prior beta-lactam intake had a current indication for penicillin therapy and were referred for testing with the major (benzylpenicilloyl polylysine) and minor (minor determinant mixture) penicillin determinants from the inpatient and outpatient service of Athens University Dermatological hospital from January 2000 to December 2002. The prevalence of positive skin tests in the total group and in those patients with vague and convincing histories of penicillin allergy was determined. Positive skin tests were observed in 19/638 (3%) of the total group, 5 out of 542 (0.9%) patients without any history of penicillin allergy, 14 out of 96 (14.6%) patients with vague history (confidence interval [CI] 95% = 5.95-59.92), and 13 out of 18 (72.2%) patients with a convincing history of type I hypersensitivity reaction (chi2 = 286.3: odds ratio = 281.3: CI 95% = 62.19-1440.8). Patients with a vague history of penicillin allergy are 18 times more likely to have a positive penicillin skin test, and a convincing reaction history increases the likelihood by 281-fold compared with patients without a history of penicillin allergy. However, the fact that 5 of 18 (27.8%) patients with a convincing history were negative when skin tested points out that skin testing is helpful if the need for penicillin administration is compelling.

    BACKGROUND: Delayed presentation of splenic trauma is a well described entity. METHOD: We report two patients who presented with splenic abnormality found incidentally on imaging for other medical problems. A remote history of splenic trauma was elicited during clinical evaluation; 18 months in one patient and 11 years in the second patient. Both patients underwent surgical exploration. CONCLUSIONS: Radiological investigations could not reassure us that the splenic abnormalities were benign, and their management was the subject of some debate.

    Visual interpretation of iodine-123-beta-15-(p-iodophenyl)-3(R,S)-methyl-pentadecanoic acid ({sup 123}I-BMIPP) myocardial images cannot easily detect mild reduction in tracer uptake. Objective assessment of myocardial {sup 123}I-BMIPP maldistributions at rest was attempted using a bull`s-eye map and its normal data file for detecting myocardial damage in patients with mitochondrial encephalomyopathy. Six patients, two with Kearns-Sayre syndrome and four with mitochondrial myopathy, encephalopathy, lactic acidosis, and strokelike episodes (MELAS), and 10 normal subjects were studied. Fractional myocardial uptake of 1{sup 23}I-BMIPP was also measured by dynamic static imaging to assess the global myocardial free fatty acid. These data were compared with the cardiothoracic ratio measured by chest radiography and left ventricular ejection fraction assessed by echocardiography. Abnormal cardiothoracic ratio and lower ejection fraction were detected in only one patient with Kearns-Sayre syndrome. Abnormal fractional myocardial uptake was detected in two patients (1.61%, 1.91%), whereas abnormal regional {sup 123}I-BMIPP uptake assessed by the bull`s-eye map was detected in five patients (83%). All patients showed abnormal uptake in the anterior portion, and one showed progressive atrioventricular conduction abnormality and systolic dysfunction with extended {sup 123}I-BMIPP abnormal uptake. The results suggest that assessment based on the normal data file in a bull`s-eye polar map is clinically useful for detection of myocardial damage in patients with mitochondrial encephalomyopathy.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) represent one of the most frequent causes of drug-induced urticaria/angioedema worldwide. Recent review articles have classified patients experiencing NSAID-induced urticaria/angioedema into different categories, including single reactors, multiple reactors, and multiple reactors with underlying chronic urticaria. Each of these categories requires a different clinical approach. The present article, written by a panel of experts, reports the main recommendations for the practical clinical management of patients with a history of urticaria/angioedema induced by multiple NSAID based on current knowledge.

    Epidermolysis bullosa (EB) is a rare skin disorder characterized by blister formation in response to minor trauma and accompanied by extracutaneous manifestations. The use of endosseous implants to support fixed prostheses for the rehabilitation of patients with recessive dystrophic EB might provide a considerably better clinical treatment outcome than traditional prosthodontic interventions. This case history report describes the clinical management of such an afflicted patient. Implants were placed immediately following teeth extractions and subsequently loaded with fixed full-arch prostheses. This treatment option is proposed for patients with recessive dystrophic EB to preclude mucosal irritation associated with wearing removable prostheses.

    AIM To describe the pathophysiology, clinical presentation,natural history, and therapy of portal hypertensivegastropathy (PHG) based on a systematic literaturereview.METHODS: Computerized search of the literature wasperformed via PubMed using the following medicalsubject headings or keywords: "portal" and "gastropathy";or "portal" and "hypertensive"; or "congestive"and "gastropathy"; or "congestive" and "gastroenteropathy".The following criteria were applied for studyinclusion: Publication in peer-reviewed journals, andpublication since 1980. Articles were independentlyevaluated by each author and selected for inclusionby consensus after discussion based on the followingcriteria: Well-designed, prospective trials; recent studies;large study populations; and study emphasis on PHG.RESULTS: PHG is diagnosed by characteristic endoscopicfindings of small polygonal areas of variableerythema surrounded by a pale, reticular border in amosaic pattern in the gastric fundus/body in a patientwith cirrhotic or non-cirrhotic portal hypertension. Histologicfindings include capillary and venule dilatation,congestion, and tortuosity, without vascular fibrinthrombi or inflammatory cells in gastric submucosa.PHG is differentiated from gastric antral vascular ectasiaby a different endoscopic appearance. The etiology ofPHG is inadequately understood. Portal hypertensionis necessary but insufficient to develop PHG becausemany patients have portal hypertension without PHG.PHG increases in frequency with more severe portalhypertension, advanced liver disease, longer liver diseaseduration, presence of esophageal varices, and endoscopicvariceal obliteration. PHG pathogenesis is related to ahyperdynamic circulation, induced by portal hypertension,characterized by increased intrahepatic resistance toflow, increased splanchnic flow, increased total gastricflow, and most likely decreased gastric mucosal flow.Gastric mucosa in PHG shows increased

    Although a variant of primary biliary cirrhosis (PBC) characterized by features of autoimmune hepatitis (AIH) has been recognized for many years, few studies with ample numbers of patients have focused on its natural history. This study aimed to clarify the natural history, prognosis, and response to therapy in a cohort of patients with PBC with AIH features. We retrospectively analyzed 277 PBC patients without AIH features and 46 PBC patients with AIH features seen between September 2004 and April 2014. The 5-year adverse outcome-free survival of PBC patients with AIH features was 58% compared to 81% in PBC patients without AIH features. Multivariate analysis in the patients with AIH features indicated that total bilirubin ≥ 2.70× the upper limit of normal predicted a poor prognosis (p = 0.008, relative risk 8.39, 95% confidence interval (CI) 1.73, 40.73). Combination therapy with ursodeoxycholic acid (UDCA) and immunosuppression provided better short-term responses in PBC patients with AIH features, defined by multiple criteria. Higher aspartate aminotransferase (AST) level at accession suggested better prognosis for PBC patients with AIH features while worse prognosis for PBC patients without AIH features. PBC patients with AIH features differ from those without AIH features in terms of natural history, prognostic indicators, and response to therapy.

    Full Text Available Abstract The review presents pediatric adverse drug events from a historical perspective and focuses on selected safety issues associated with off-label use of medications for the psychiatric treatment of youth. Clinical monitoring procedures for major psychotropic drug classes are reviewed. Prior studies suggest that systematic treatment monitoring is warranted so as to both minimize risk of unexpected adverse events and exposures to ineffective treatments. Clinical trials to establish the efficacy and safety of drugs currently being used off-label in the pediatric population are needed. In the meantime, clinicians should consider the existing evidence-base for these drugs and institute close clinical monitoring.

    . Gene profiling analysis shows that the expression of several genes is deregulated including PDGFRA (platelet-derived growth factor receptor) gene, encoding a receptor with tyrosine kinase activity. In angio-immunoblastic T-cell lymphomas molecular abnormalities are found in follicular helper T-cell (TFH) that express some distinctive markers such as CD10, PD-1, CXCR5 and the CXCL13 chemokine. ALK-positive anaplastic large cell lymphoma is a paradigme of T-cell lymphoma since it is associated with an X-ALK oncogenic fusion protein due to a translocation involving ALK gene at 2p23. ALK tyrosine kinase activates downstream pathways (Stat3/5b, Src kinases, PLCγ, PI3 kinase) implicated in lymphomagenesis, proliferation and protection against apoptosis. Specific ALK inhibitors are currently in clinical evaluation. Lastly several lymphomas are associated with infectious agents that play a direct (EB virus, HTLV1) or indirect role (e.g. Helicobacter pylori in MALT lymphoma) in lymphomagenesis.

    Berlucchi, Giovanni

    2010-01-01

    This chapter reviews a number of historical contributions of neurophysiology to clinical neurology in the hundred years that have elapsed since the publication of Sherrington's The Integrative Action of the Nervous System, a book generally considered the neurophysiologist's bible. In the past, many normal nervous functions have been inferred from disorderly functions in animals by neurophysiologists and in humans by clinical neurologists. If neurophysiologists have undoubtedly learned much from experimental lesions in animals, it has been the clinical neurologists who have obtained first-hand information on the effects of pathology on the functioning of the most complex and interesting of all nervous systems, that of man. Currently this division of labor is less clear, and convergent evidence from neurophysiology and clinical neurology alike has set our current knowledge about brain functions on a firm comparative foundation. This review of the relations between neurophysiology and clinical neurology reports contributions that have been recognized as "historical" by the scientific community because of their documented impact on the development of the entire field of neurosciences. The inclusion of further less famous neurophysiological achievements is justified by their potential influence on the advancement of neuroscience, as seen from the author's personal viewpoint.

    Our objective was to study the clinical characteristics and natural history of monomelic amyotrophy (MMA). We used a retrospective study of 279 patients diagnosed to have either upper (Hirayama disease) or lower limb MMA. Results showed that brachial MMA (BMMA) occurred in 224 patients (male:female, 9:1). Mean age of onset was 19.5 ± 4.18 years. Progression occurred over less than five years in the majority (95.9%) of patients. Duration at the last follow-up was: up to five years in 61.4%, 5-10 in 21.3%, 10-15 in 7.2%, > 15 years in 10.1%. MRI showed asymmetrical lower cervical cord atrophy in 44.6% of patients. Crural MMA (CMMA) occurred in 55 patients (male:female, 13:1). Mean age of onset was 21.38 ± 5.3 years. Similar to BMMA, most cases (65.5%) had onset between 15 and 25 years of age. Total duration of illness at the last follow-up was up to five years in 52.7%, 10 and beyond in 47.3%. In conclusion, a large cohort of patients with monomelic amyotrophy seen over 35 years (1976-2010) is described. Study data support the clinical findings and its natural history with long term follow-up, and the findings emphasize that monomelic amyotrophy is a 'benign' condition with a self-limiting course.

    The extent to which a family history of mood disorders and suicide could impact on clinical features of patients suffering from major depression (MD) and bipolar disorder (BD) has received relatively little attention so far. The aim of the present work is, therefore, to assess the clinical implications of the presence of at least one first- and/or second-degree relative with a history of MD, BD and suicide in a large sample of patients with MD or BD. One thousand one hundred and fifty-seven subjects with MD and 686 subjects with BD were recruited within the context of two large projects. The impact of a family history of MD, BD, and suicide-considered both separately and together-on clinical and socio-demographic variables was investigated. A family history of MD, BD, and suicide was more common in BD patients than in MD patients. A positive family history of mood disorders and/or suicide as well as a positive family history of MD and BD separately considered, but not a positive history of suicide alone, were significantly associated with a comorbidity with several anxiety disorders and inversely associated with age of onset. The clinical implications as well as the limitations of our findings are discussed.

    Full Text Available The Central Drugs Standard Control Organisation and its chairman Drug Controller general of India are bequeathed to protect the citizens from the marketing of unsafe medication. The startling findings, of the 59 th report of the Parliamentary Standing Committee on Health and Family Welfare, have uncovered the lax standards followed by the regulatory authorities in India. The growing clinical research after the product patents rights for the pharmaceutical industries as per the trade related aspects of intellectual property rights agreement and adverse drug reaction monitoring of the marketed drugs have raised many ethical and regulatory issues regarding the promotion of new drugs in Indian markets. Many controversial group of medicines; unauthorised and irrational FDCs not relevant to India′s medical needs, are available which are not sold in any of the countries with matured regulatory bodies. It becomes vital to understand the history, growth and evolution of the regulatory aspects of drugs which are handled by multiple Ministries and Departments of the Government of India. Although amendment to Schedule Y, registration of Contract Research Organisations, registration of Clinical Trials, Speeding up review process, Pharmacovigilance (PhV programme for India and Inspection of clinical trial sites have been started by the various regulatory agencies. However due to casual approach in marketing approval for sale of the drugs, the unethical steps taken by some pharmaceutical companies and medical practitioners has reiterated the need to get appropriate understanding of present regulation of drugs and clinical research especially regarding the practical rules and regulations.

    Two adult female rock hyraxes (Procavia capensis) at the Dallas Zoo were confirmed with spontaneous diabetes mellitus from 1997-2000, whereas a third animal with a similar clinical presentation never became hyperglycemic. The pancreas in all three animals showed pancreatic islet fibrosis (PIF). Retrospective examination of medical records for rock hyraxes acquired by this collection or born into it from 1991-2002 identified eight more animals affected with PIE All affected animals, including three males and eight females, were 1-7 yr of age and presented either with vague clinical signs of soft feces and rough hair coat or were acutely moribund or dead. Clinical pathology data was available for seven of the animals before onset of overt clinical signs and revealed inappropriate hyperglycemia in six, as well as elevated serum concentrations of creatine phosphokinase, amylase, and lipase in all seven animals. Pedigree evaluation did not support a familial pattern for PIE Review of the histopathology findings from nine other zoologic collections with rock hyrax deaths during the study period identified six institutions with 12 additional cases genetically unrelated to the incident collection. Histopathology and viral serology did not support an infectious cause. Analysis of serum anti-islet and anti-insulin antibodies did not suggest autoimmune disease, and none of the animals had known exposure to toxic substances. Limited nutritional analyses did not support a nutritional basis for the condition, and the cause for PIF remains unknown.

    The provision of clinical interpretation of results, either verbally or in the printed report, may be considered an integral part of clinical biochemistry diagnostic service. Proficiency testing or external quality assessment (EQA) of such activity may be useful in education, training, continuing professional development and ensuring the quality of such service. Details of the Patient Report Comments Program (RPCProgram) developed by the Royal College of Pathologists of Australasia (RCPA) Chemical Pathology Quality Assurance Programs Pty Ltd (QAP) is described in this review. The program is aimed at pathologists, clinical scientists and trainees. Registered participants are provided a report with case details and a set of clinical biochemistry results at monthly intervals and submit an interpretative comment for the report. Comments received are broken up into components that are translated into common key phrases. An expert panel evaluates the key phrases, classifies them according to appropriateness and drafts a suggested comment, a case summary and a rationale, which are included in a summary report returned to participants. There is considerable diversity in the quality of interpretative comments received from participants of the PRCProgram. The primary purpose of EQA of interpretative commenting is educational self-assessment, and they are recognized as a continuing professional development activity. Whilst there is some evidence for the utility of interpretative comments in improving patient outcomes, evidence for the utility of EQA in improving quality of comments is awaited.

    2013-02-01

    The field of electroencephalography (EEG) had its origin with the discovery of recordable electrical potentials from activated nerves and muscles of animals and in the last quarter of the 19th century from the cerebral cortex of animals. By the 1920s, Hans Berger, a neuropsychiatrist from Germany, recorded potentials from the scalp of patients with skull defects and, a few years later, with more sensitive equipment from intact subjects. Concurrently, the introduction of electronic vacuum tube amplification and the cathode ray oscilloscope was made by American physiologists or "axonologists," interested in peripheral nerve recordings. Berger's findings were independently confirmed in early 1934 by Lord Adrian in England and by Hallowell Davis at Harvard, in the United States. In the United States, the earliest contributions to human EEG were made by Hallowell Davis, Herbert H. Jasper, Frederic A. Gibbs, William Lennox, and Alfred L. Loomis. Remarkable progress in the development of EEG as a useful clinical tool followed the 1935 report by the Harvard group on the electrographic and clinical correlations in patients with absence (petit mal) seizures and altered states of consciousness. Technical aspects of the EEG and additional clinical EEG correlations were elucidated by the above investigators and a number of others. Further study led to gatherings of the EEG pioneers at Loomis' laboratory in New York (1935-1939), Regional EEG society formation, and the American Clinical Neurophysiology Society in 1946.

  15. Abnormal Grief: Should We Consider a More Patient-Centered Approach?

    2015-01-01

    Grief, the psychological reaction to the loss of a significant other, varies complexly in its cause, experience, evolution, and prognosis. Although most bereaved individuals experience a normal grieving process, some develop complicated grief (CG) or major depressive disorder (MDD). The DSM-5, which controversially altered the nosology, recognizes grief-related major depression (GRMD) as a diagnostic subtype if a patient meets MDD criteria two weeks post bereavement. The (DSM-5) tries to distinguish between grief and MDD, but remains a symptom-based, centered approach to grief that is not patient centered. This article reviews grief in its normal and abnormal dimensions. Using an illustrative clinical case in which interpersonal psychotherapy (IPT) was employed, we discuss the need for a more patient-centered approach to treating abnormal grief, considering the patient's personal history, perceptions, experiences of bereavement, and interpersonal environment. Clinical studies need to better identify subgroups of individuals susceptible to abnormal grief and to evaluate their response to early interventions.

    Full Text Available Objective: Alcohol is most commonly abused drug worldwide. It has been shown to produce toxic effects in almost every organ system in the body. Many of these medical conditions can be attributed to direct effects of alcohol whereas others are indirect sequelae that may result from nutritional deficiencies or predisposition to trauma. Alcohol consumption has been associated with a variety of cardio vascular disorders this study was thus undertaken to know the Electrocardiographic and Echocardiographic abnormalities in asymptomatic chronic alcoholic patients. Materials and Methods: 50 Patients attending the out-patient clinic & who were admitted in Al Ameen Medical College Hospital and District hospital, Bijapur were selected for the study. It was a prospective study design subjects in age group 20-40, having history of chronic alcoholism as defined, for more than 5 years were evaluated by electrocardiography and echocardiography. Patients with known diabetics, hypertensive and cardiovascular disorders were excluded from the study group. Results: The prevalence of cardiovascular abnormalities in patients of chronic alcoholism is 37% in our study. Most common ECG changes are sinus tachycardia (18%, and Non specific ST-T changes (9%. Most common 2D ECHO changes was increased posterior wall thickness (11% and followed by increased interventricular septum thickness and decreased ejection fraction (<40%. The prevalence of cardio vascular abnormalities are more with increased duration of alcohol consumption and also high in advanced age group. Conclusions: This study confirms that many electrocardiographic as well as echocardiographic changes occur prior to symptomatic cardiac disorders established to be caused by chronic alcohol intake such as alcoholic cardiomyopathy .which probably are early indictors of ongoing effects of alcohol and are reversible during the early stages detected by non invasive investigations like Electrocardiography and

    A total of 152 patients with asbestos-related lung cancer recognized by the criteria of Japanese compensation law for asbestos-related diseases were examined and compared with 431 patients with non-asbestos-related lung cancer. Male comprised 96% of patients. Ages ranged from 50 to 91 years with a median of 72 years. Eighty-nine percent were smokers or ex-smokers. Almost all patients had occupational histories of asbestos exposure. The median duration of asbestos exposure was 31 years and the median latency period was 47 years. Thirty-four percent of patients exhibited asbestosis and 81% exhibited pleural plaques by radiography. Regarding asbestos particles in the lung for 73 operated or autopsied patients, 62% had more than 5,000 particles per gram. On the other hand, 100% of non-asbestos-related lung cancer patients had <5000 particles per gram with a median of 554 particles. The number of asbestos bodies in the lung, male gender, absence of symptoms, smoking index, and early stage of cancer were significantly much more than those of non-asbestos-related lung cancer. In this study, a diagnosis of asbestos-related lung cancer was made in 34% of patients by asbestosis, in 62% by presence of both pleural plaques and more than 10 years' occupational asbestos exposure, and in 4% by more than 5000 asbestos particles per gram of lung tissue. Occupational histories, duration of asbestos exposure, and pleural plaques are common categories for the recognition of asbestos-related lung cancer in Japan.

    Although it has been more than two decades since brain mapping was introduced in medicine, its scientific value and clinical practice have not been proved. This paper makes an overview about the historical development of brain mapping, its usefulness in psychiatry and lays epistemological issues concerning the role of technology in medical settings. Both historical and technological development of qEEG gives us the opportunity to think about complexity between ethics, science, technology and medicine.

  19. A history of deep brain stimulation: Technological innovation and the role of clinical assessment tools

    Science.gov (United States)

    2013-01-01

    Deep brain stimulation involves using a pacemaker-like device to deliver constant electrical stimulation to problematic areas within the brain. It has been used to treat over 40,000 people with Parkinson’s disease and essential tremor worldwide and is currently undergoing clinical trials as a treatment for depression and obsessive–compulsive disorder. This article will provide an historical account of deep brain stimulation in order to illustrate the plurality of interests involved in the development and stabilization of deep brain stimulation technology. Using Latour’s notion of immutable mobiles, this article will illustrate the importance of clinical assessment tools in shaping technological development in the era of medical device regulation. Given that such tools can serve commercial and professional interests, this article suggests that it is necessary to scrutinise their application in research contexts to ensure that they capture clinical changes that are meaningful for patients and their families. This is particularly important in relation to potentially ethically problematic therapies such as deep brain stimulation for psychiatric disorders.

    Neuroendocrine abnormalities are common in Parkinson's disease (PD) and include disruption of melatonin secretion, disturbances of glucose, insulin resistance and bone metabolism, and body weight changes. They have been associated with multiple non-motor symptoms in PD and have important clinical consequences, including therapeutics. Some of the underlying mechanisms have been implicated in the pathogenesis of PD and represent promising targets for the development of disease biomarkers and neuroprotective therapies. In this systems-based review, we describe clinically relevant neuroendocrine abnormalities in Parkinson's disease to highlight their role in overall phenotype. We discuss pathophysiological mechanisms, clinical implications, and pharmacological and non-pharmacological interventions based on the current evidence. We also review recent advances in the field, focusing on the potential targets for development of neuroprotective drugs in Parkinson's disease and suggest future areas for research.

    Abstract Objective. To clarify the clinical significance of antiphospholipid antibody (aPL) profile in patients with obstetric antiphospholipid syndrome (APS). Methods. Clinical records of 13 pregnant patients (15 pregnancies) with obstetrical APS were reviewed over 10 years. Patients who met the Sapporo Criteria fully were studied, whereas those with only early pregnancy loss were excluded. In addition to classical aPL: lupus anticoagulant (LA), anticardiolipin antibody (aCL), and anti-β2-glycoprotein I (aβ2GPI); phosphatidylserine-dependent anti-prothrombin antibody (aPS/PT) and kininogen-dependent anti-phosphatidylethanolamine antibody (aPE) were also examined in each case. Results. Cases were divided into two groups according to patient response to standard treatment: good and poor outcome groups. All cases with poor outcome presented LA, with IgG aβ2GPI and IgG aPS/PT were also frequently observed. IgG aPE did not correlate with pregnancy outcome. Conclusion. aPL profile may predict pregnancy outcome in patients with this subset of obstetric APS.

  3. Betahistine in the treatment of vertigo. History and clinical implications of recent pharmacological researches.

    A short profile of betahistine and its activity in treatment of Menière's disease and other forms of peripheral vertigo is presented. The clinical efficacy of betahistine is documented by a series of more than twenty controlled clinical studies, performed in the years 1966-2000. Basic researches initially proved that bethaistine acts trough a vasodilating action on inner ear and cerebral blood flow (Suga and Snow, 1969; Martinez, 1972). In the following years this activity was confirmed using the modern laser doppler flowmetry technique (Laurikainen et al, 1998). Further recent studies proved that betahistine acts on the central vestibular histaminergic system as a weak H1 agonist and a strong H3 antagonist (Arrang et al., 1985), improving the process of vestibular compensation (Tighilet et al., 1995) as well as on peripheral labyrinthine receptors, reducing the spontaneous firing rate but not the activity induced by thermal or mechanical stimulation (Botta et al., 1998). More than forty years after its discovery, this series of studies carried out in the second half of the 90s leads to the conclusion that betahistine is a drug which maintains its scientific interest and its pharmacological potential in the treatment of vertigo.

    Andrea Pasta was an eclectic visionary light years ahead of his time. He made numerous contributions to the field of medicine, some recognized by his contemporaries and others so visionary that they are being applied only in modern times. His contributions spanned the disciplines of psychology, gynaecology, haematology, infectious diseases and the doctor-patient relationship. Well known among his contemporaries, he combined a passion for clinical medicine and a keen interest in history and art with a strict research methodology and an approach to caring for patients as human beings. By studying his life and works, we can better understand the magnitude and significance of his innovative method and its applicability in modern times and also the significance of his many contributions.

    Since Robert Koch identified Mycobacterium tuberculosis as causative agent of tuberculosis (TB) in 1882, TB research has developed in various fields, such as bacteriology, immunology, genomic study and genetic susceptibility. These research results have led to the knowledge concerning cellular immunity and the development of biochemical and gene diagnostic approach for M. tuberculosis, interferon-gamma release assay for latent TB infection and epidemiologic study using variable numbers of tandem repeats. After Selman A. Waksman isolated streptomycin, various drugs came to be used. Standard of the TB treatments has been revised several times up to now. Discovery of the novel drugs potential for multidrug-resistant TB is challenged. Close relationships among basic research, clinical medicine and health service are crucial to improving global control of TB.

  6. From clinical judgment to odds: a history of prognostication in anoxic-ischemic coma.

    Persistent coma from a major anoxic-ischemic injury to the brain may indicate there is less chance for full recovery. The tools of prognostication to assess comatose survivors of cardiopulmonary resuscitation have developed over several decades. Physicians would initially base their judgment on experience and data on outcome in these patients in the early years were merely on awakening not on disability. In the late 1970s, a large multicenter prospective study was performed on outcome in nontraumatic coma. The impetus for this study was the result of Plum and Jennet's collaboration. In 1981--for the first time--complex statistics were used to improve the accuracy of prognosis and became known as the "Levy algorithms." These early seminal studies shaped the prediction models and implied that clinical information alone could assist physicians in making a prediction. Later, probabilistic methods became more commonplace.

    2009-01-01

    Full Text Available The complications associated with acquiring and storing whole blood for transfusions have launched substantial efforts to develop a blood substitute. The history of these efforts involves a complicated mixture of science, ethics, and business. This review focuses on clinical trials of the three hemoglobin-based oxygen carriers (HBOC that have progressed to Phase II or III clinical trials: HemAssist (Baxter; Deerfield, IL, US, PolyHeme (Northfield; Evanston, IL, US, and Hemopure (Biopure; Cambridge, MA, US. Published animal studies and clinical trials carried out in a perioperative setting have demonstrated that these products successfully transport and deliver oxygen, but all may induce hypertension and lead to unexpectedly low cardiac outputs. Overall, these studies suggest that HBOCs resulted in only modest blood saving during and after surgery, no improvement in mortality and an increased incidence of adverse reactions. To date, the results from these perioperative studies have not led to regulatory approval. All three companies instead chose to focus their efforts on large trials of trauma patients in the pre-hospital setting. Baxter abandoned the development of HemAssist after a trial in the U.S. was prematurely halted when the first 100 patients showed significantly increased mortality rates as compared to patients treated with blood products. Northfield's PolyHeme trial demonstrated a non-significant trend towards increased mortality and a very modest reduction in the subsequent need for blood. The testing of Biopure's Hemopure for trauma patients has been halted for several years because of FDA concerns over trial design and study justification. Ethical concerns have also been raised regarding the design and implementation of all HBOC clinical trials. Thus, the available evidence suggests that HemAssist, Polyheme, and Hemopure are associated with a significant level of cardiovascular dysfunction. The next generation of HBOCs remains

    Full Text Available Background: AUB is a common but complicated clinical presentation and occurs in 15-20% of women between menarche to menopause and significantly affects the women's health. Women with thyroid dysfunction often have menstrual irregularities, infertility and increased morbidity during pregnancy. The objective of present study is to find the correlation between thyroid disorders and AUB in perimenopausal women attending gynecology OPD. Methods: In the present study, fifty five patients with AUB were included and were evaluated for the cause including thyroid abnormality. Thyroid function tests were done in all patients. Results: Among 55 patients, 12 patients were diagnosed as hypothyroidism and 7 as hyperthyroidism, women with AUB 36 (65.4% were euthyroid. Among 19 women with thyroid abnormality, heavy menstrual bleeding was seen in 8 (42% women, 6 (31.57% had polymenorrhagia, 5 (26.31% had oligomenorrhoea. The frequent menstrual abnormality in women with hypothyroidism (12 women was heavy menstrual bleeding in 5 (41.6% women, 3 (25% had oligomennorhoea, 4 (33.3% had polymenorrhagia. Out of 7 women with hyperthyroidism, 2 (28.57% had oligomenorrhoea, 3 (42.8% had heavy menstrual bleeding, 2 (28.57% had polymenorrhagia. In a total of 55 patients with AUB, 11 (20% had structural abnormalities in uterus and ovaries. 5 (9% had adenomyosis, 3 (5.4% had ovarian cysts, 3 (5.4% had fibroids. Conclusions: It is important to screen all women for thyroid abnormality who are presenting with AUB especially with non-structural causes of AUB. Correction of thyroid abnormalities also relieves AUB. This will avoid unnecessary hormonal treatment and surgery. [Int J Res Med Sci 2015; 3(11.000: 3250-3253

    2016-01-01

    Recent advances in high-throughput molecular testing have made it possible to diagnose most genetic disorders relatively early in gestation with minimal risk to the fetus. These advances should soon allow widespread prenatal screening for the majority of human genetic diseases, opening the door to the possibility of treatment/correction prior to birth. In addition to the obvious psychological and financial benefits of curing a disease in utero, and thereby enabling the birth of a healthy infant, there are multiple biological advantages unique to fetal development, which provide compelling rationale for performing potentially curative treatments, such as stem cell transplantation or gene therapy, prior to birth. Herein, we briefly review the fields of in utero transplantation (IUTx) and in utero gene therapy and discuss the biological hurdles that have thus far restricted success of IUTx to patients with immunodeficiencies. We then highlight several recent experimental breakthroughs in immunology, hematopoietic/marrow ontogeny, and in utero cell delivery, which have collectively provided means of overcoming these barriers, thus setting the stage for clinical application of these highly promising therapies in the near future.

    1994-03-01

    Music-thanatology is a palliative medical modality employing prescriptive music to tend the complex physical and spiritual needs of the dying. "Infirmary music" was an intimate expression of French monastic medicine in 11th-century Cluny and anticipated the holism of both the hospice and palliative medical movements by almost 800 years. Although no longer an expression of any institutional religious identity, music-thanatology is nevertheless concerned with the possibility of a blessed death and the gift that conscious dying can bring to the fullness of life. Music-thanatology interns seek to integrate and model these contemplative and clinical values in daily practice: 18 interns deliver prescriptive music in bedside vigils serving the dying in home, hospital, and hospice settings with great effectiveness in oncology, respiratory illnesses, the slow degenerative diseases, and AIDS. This article is submitted to nurses to serve as an introduction to the field of music-thanatology, providing readers with a brief history, meaningful clinical narratives, some of the musical theories involved, research concerns (archival and medical), and milestones to be addressed for the future implementation of music-thanatology in hospitals and hospices and communities across the nation.

    A previous report suggests a substantial incidence of exertional rhabdomyolysis (ER) in Arabian horses performing endurance racing. This study compared formalin histopathology and clinical and metabolic responses to a standardised field exercise test (SET) between Arabians with and without ER. Arabian horses with (n = 10; age 15.4 ± 5.6 years) and without (n = 9; 12.9 ± 6.1 years) prior ER were stall-rested for 24-48 h, after which paired ER and control horses were fitted with a telemetric ECG and performed a 47 min submaximal SET. Plasma glucose, lactate, electrolyte and total protein concentrations and packed cell volume were measured before and immediately after exercise. Blood and percutaneous gluteal muscle samples were also obtained before and 3 h after exercise for measurement of plasma creatine kinase (CK) activity and muscle glycogen concentration, respectively. Histopathologic analysis of formalin-fixed pre-exercise muscle sections was performed. Data were analyzed by ANOVA and non-parametric tests (P exercise, and plasma CK increased similarly in ER and control Arabians. Muscle glycogen, heart rate, and remaining plasma variables did not differ between horses with ER and control horses. Horses with ER had more internalised nuclei in mature myofibers, more aggregates of cytoplasmic glycogen and desmin, and higher myopathic scores than control horses. Although many horses with ER had histopathologic evidence of chronic myopathy, muscle glycogen concentrations and metabolic exercise responses were normal. Results did not support a consistent metabolic myopathy or a glycogen storage disorder in Arabians with ER.

    Postthrombotic syndrome (PTS) is a chronic morbidity of venous thromboembolism (VTE) in children. Information about the evolution of PTS is lacking in children. Present study was aimed to evaluate the time-course of extremity PTS in children who were serially followed in a hematology clinic. This retrospective cohort study included 69 consecutive children with documented VTEs that presented with symptoms of extremity VTE: 67 extremity VTEs with or without extension to vena cava, 2 inferior vena cava VTEs. Severity of PTS was assessed using modified Villalta scale. Median age of the cohort was 12.6 years (interquartile range 1.6-15 years) while median follow-up was 28.7 months (interquartile range 13.3-33.4 months. PTS prevalence was 46.8% [95% confidence interval (CI) 37.9-57.7%]. Lower extremity VTE was associated with development of PTS compared to upper extremity VTE regardless of catheter use (P = 0.002). The time-course of PTS fluctuated in 11 of 33 children (33%; 95% CI 20-47%) at a median interval of 12 months from diagnosis of VTE (range 4-14 months): three progressed from mild/moderate to severe, one improved from moderate to mild, seven fluctuated between mild and moderate. Recurrence and incomplete resolution of VTE were associated with variability in PTS severity (P course of PTS was not static in one third of children. Future research should focus on identifying the predictors contributing to the worsening of PTS and developing risk-stratified treatment interventions so as to improve the outcome of children with VTE.

  17. The medical management of abnormal uterine bleeding in reproductive-aged women.

    2016-01-01

    In the treatment of women with abnormal uterine bleeding, once a thorough history, physical examination, and indicated imaging studies are performed and all significant structural causes are excluded, medical management is the first-line approach. Determining the acuity of the bleeding, the patient's medical history, assessing risk factors, and establishing a diagnosis will individualize their medical regimen. In acute abnormal uterine bleeding with a normal uterus, parenteral estrogen, a multidose combined oral contraceptive regimen, a multidose progestin-only regimen, and tranexamic acid are all viable options, given the appropriate clinical scenario. Heavy menstrual bleeding can be treated with a levonorgestrel-releasing intrauterine system, combined oral contraceptives, continuous oral progestins, and tranexamic acid with high efficacy. Nonsteroidal antiinflammatory drugs may be utilized with hormonal methods and tranexamic acid to decrease menstrual bleeding. Gonadotropin-releasing hormone agonists are indicated in patients with leiomyoma and abnormal uterine bleeding in preparation for surgical interventions. In women with inherited bleeding disorders all hormonal methods as well as tranexamic acid can be used to treat abnormal uterine bleeding. Women on anticoagulation therapy should consider using progestin-only methods as well as a gonadotropin-releasing hormone agonist to treat their heavy menstrual bleeding. Given these myriad options for medical treatment of abnormal uterine bleeding, many patients may avoid surgical intervention.

    Given the widespread adoption of electronic medical records and recent emergence of electronic family history tools, we examined genetic counselors' perspectives on the emerging technology of the personal health record (PHR)-based family history tool that links to an electronic medical record (EMR). Two-hundred thirty-three genetic counselors responded to an on-line survey eliciting current use of electronic family history (EFH) tools and familiarity with PHR-based family history tools. Additionally, after being shown a series of screen shots of a newly developed PHR-based family history tool based on the U.S. Surgeon General's My Family Health Portrait (United States Department of Health and Human Services 2009), participants were surveyed about the perceived usefulness, ease of use, and impact on current workflow that this kind of tool would have in their practices. Eighty-three percent reported that their institution has an EMR, yet only 35 % have a dedicated space for family history. Eighty-two percent reported that less than 5 % of their patients have a PHR, and only 16 % have worked with patients who have a PHR. Seventy-two percent or more agreed that a PHR-based family history tool would facilitate communication, increase accuracy of information, ensure consistency in recording information, increase focus on actual counseling, reduce repetitive questions, improve efficiency, and increase the legibility and clarity. Our findings suggest that participants were familiar with existing EFH tools, but that the majority did not use them in practice. Genetic counselors' adoption of such tools is limited due to non-existence of this kind of technology or inability to integrate it into their clinics. They are also strongly in favor of adopting a PHR-based family history tool in genetics clinics, but have practical concerns that must be addressed before the tool can be implemented.

    Meiotic anomalies, as reviewed here, are synaptic chromosome abnormalities, limited to germ cells that cannot be detected through the study of the karyotype. Although the importance of synaptic errors has been underestimated for many years, their presence is related to many cases of human male infertility. Synaptic anomalies can be studied by immunostaining of synaptonemal complexes (SCs), but in this case their frequency is probably underestimated due to the phenomenon of synaptic adjustment. They can also be studied in classic meiotic preparations, which, from a clinical point of view, is still the best approach, especially if multiplex fluorescence in situ hybridization is at hand to solve difficult cases. Sperm chromosome FISH studies also provide indirect evidence of their presence. Synaptic anomalies can affect the rate of recombination of all bivalents, produce achiasmate small univalents, partially achiasmate medium-sized or large bivalents, or affect all bivalents in the cell. The frequency is variable, interindividually and intraindividually. The baseline incidence of synaptic anomalies is 6-8%, which may be increased to 17.6% in males with a severe oligozoospermia, and to 27% in normozoospermic males with one or more previous IVF failures. The clinical consequences are the production of abnormal spermatozoa that will produce a higher number of chromosomally abnormal embryos. The indications for a meiotic study in testicular biopsy are provided.

    The objective of this study was to assess the frequency of gait abnormalities and lameness (GAL) in bitches with pyometra, and their association with clinical and laboratory findings. The study included 79 bitches diagnosed with pyometra and 35 negative control intact bitches presented with other soft tissue surgical disorders. Dogs with a history of chronic lameness due to orthopaedic or neurological origin were excluded. A history of GAL was more frequent in the pyometra group (47 per cent) compared with the control group (20 per cent) (P=0.007). In the pyometra group, bitches presenting GAL had (P<0.04) higher frequencies of closed-cervix pyometra, anorexia and vomiting, as well as higher serum creatinine concentration and muscle enzymes activity, compared with those in without GAL. GAL signs resolved postovariohysterectomy in all but one bitch. The results suggest that GAL signs occur frequently in bitches with pyometra, especially in closed-cervix disease. Therefore, pyometra should be considered among the differential diagnoses when GAL occurs, especially when the clinical signs are non-specific and the reproductive history is unclear.

    Acute inversion injuries of the ankle are the most common sports accidents, accounting for approximately 10% of emergency room admissions. In up to 85%, an injury of the lateral collateral ligaments is observed. Classically, the assessment of these injuries has relied on clinical examination and radiographs, including stress views. The aim of our study was to correlate prospectively the findings of high-field 3 T MRI in acute ankle distortion with clinical outcome. During a 6-month period, 38 patients were prospectively included. MRI was performed within 48 h of trauma and clinical examination using a protocol consisting of axial T2-weighted and coronal and sagittal T1-weighted images and a sagittal proton density (PDw) sequence. Each ligament injury was graded on a three-point scale. Functional outcome was evaluated using the AOFAS ankle-hindfoot scale. In 24/38 patients (63.12%), ligament injury was observed. In 22/24 cases, this was an injury of the lateral ligaments and in 2/24 cases of the medial ligaments. Injury of the syndesmosis occurred in three patients, a bone bruise in four, and an osteochondral lesion in three cases. Patients with an injury of two or more ligaments or a bone bruise had a lower AOFAS score and returned to sports activities and full weight-bearing later (P < 0.01). MR imaging at 3 Tesla is an independent predictor for clinical outcome. Therefore MRI may be beneficial in those cases where the findings influence further treatment. (orig.)

    Genomic copy number microarrays have significantly increased the diagnostic yield over a karyotype for clinically significant imbalances in individuals with developmental delay, intellectual disability, multiple congenital anomalies, and autism, and they are now accepted as a first tier diagnostic test for these indications. As it is not feasible to validate microarray technology that targets the entire genome in the same manner as an assay that targets a specific gene or syndromic region, a new paradigm of validation and regulation is needed to regulate this important diagnostic technology. We suggest that these microarray platforms be evaluated and manufacturers regulated for the ability to accurately measure copy number gains or losses in DNA (analytical validation) and that the subsequent interpretation of the findings and assignment of clinical significance be determined by medical professionals with appropriate training and certification. To this end, the American College of Medical Genetics, as the professional organization of board-certified clinical laboratory geneticists, herein outlines recommendations for the design and performance expectations for clinical genomic copy number microarrays and associated software intended for use in the postnatal setting for detection of constitutional abnormalities.

    Full Text Available BACKGROUND: Therapeutic intervention with low-density lipoprotein cholesterol-lowering agents known as statins has been demonstrated to reduce cardiovascular risk. However, many patients on statin treatment have persistent dyslipidemia and remain at a high risk of cardiovascular disease. Therefore, the objective of this study was to assess the frequency of lipid abnormalities in patients receiving chronic statin treatment. METHODS: As part of an international, cross-sectional, observational study, DYSIS-Middle East enrolled 2,182 patients in the United Arab Emirates (UAE, Saudi Arabia, Lebanon and Jordan. All patients were over 45 years of age and had been on statin treatment for at least three months. Data on demographics, lipid parameters and cardiovascular risk profile were recorded. Cardiovascular risk was defined according the guidelines of the European Society of Cardiology. RESULTS: The majority of patients (82.6% were classified as being at very high risk of cardiovascular events, and 61.8% of all patients did not attain LDL-C target levels. Low high-density lipoprotein cholesterol levels and elevated triglyceride levels were noted in 55.5% and 48.5% of patients, respectively. Multivariate logistical regression modeling indicated that factors independently associated with LDL-C levels not being at goal were lifestyle choices, diabetes mellitus, ischemic heart disease, and blood pressure ≥ 140/90 mmHg. CONCLUSIONS: Almost two-thirds of statin-treated patients in the United Arab Emirates, Saudi Arabia, Lebanon and Jordan had inadequately controlled lipid levels. More comprehensive surveillance, awareness and treatment regimens, as well as modification of lifestyle choices, is necessary to halt the rise in cardiovascular disease-related mortality.

    Mentalis muscle responses to electrical stimulation of the zygomatic branch of the facial nerve are considered abnormal muscle responses (AMRs) and can be used to monitor the success of decompression in microvascular decompression (MVD) surgery. The aim of this study was to compare the long-term outcome of MVD surgery in which the AMR disappeared to the outcome of surgery in which the AMR persisted. From 2005 to 2009, 131 patients with hemifacial spasm received MVD surgery with intraoperative monitoring of AMR. At 1 week postsurgery, spasms had resolved in 82% of cases in the AMR-disappearance group and 46% of cases in the persistent-AMR group, mild spasms were present in 10% of cases in the AMR-disappearance group and 31% of cases in the persistent-AMR group, and moderate were present spasms in 8% of cases in the AMR-disappearance group and 23% of cases in the persistent-AMR group (P spasms had resolved in 92% of cases in the AMR-disappearance group and 84% of cases in the persistent-AMR group, mild spasms were present in 6% of cases in the AMR-disappearance group and 8% of cases in the persistent-AMR group, and moderate spasms were present in 3% of cases in the AMR-disappearance group and 8% of the cases in the persistent-AMR group (P = 0.56). These results indicate that the long-term outcome of MVD surgery in which the AMR persisted was no different to that of MVD surgery in which the AMR disappeared.

    Freud's psychodynamic theory is predominantly based on case histories of patients who displayed abnormal behavior. From a scientific point of view, Freud's analyses of these cases are unacceptable because the key concepts of his theory cannot be tested empirically. However, in one respect, Freud was totally right: most forms of abnormal behavior…

    Abnormal protein aggregation or amyloid is the major cause ofmany neurodegenerative disorders. The present review focuses on the correlation between sequence and structure features of proteins related to the diseases and abnormal protein aggregation. Recent progress has improved our knowledge on understand-ing the mechanism of amyloid formation. We suggest a nucleation model for ordered protein aggregation, which can also explain pathogenesis mechanisms of these neurodegenerative diseases in vivo.

    In 1960, J. Anthony Morris, a molecular biologist at the US National Institutes of Health conducted one of the only non-therapeutic clinical studies of the cancer virus SV40. Morris and his research team aimed to determine whether SV40 was a serious harm to human health, since many scientists at the time suspected that SV40 caused cancer in humans based on evidence from in vivo animal studies and experiments with human tissue. Morris found that SV40 had no significant effect but his claim has remained controversial among scientists and policymakers through the present day--both on scientific and ethical grounds. Why did Morris only conduct one clinical study on the cancer-causing potential of SV40 in healthy humans? We use the case to explain how empirical evidence and ethical imperatives are, paradoxically, often dependent on each other and mutually exclusive in clinical research, which leaves answers to scientific and ethical questions unsettled. This paper serves two goals: first, it documents a unique--and uniquely important--study of clinical research on SV40. Second, it introduces the concept of "the stowaway," which is a special type of contaminant that changes the past in the present moment. In the history of science, stowaways are misfortunes that nonetheless afford research that otherwise would have been impossible specifically by creating new pasts. This case (Morris' study) and concept (the stowaway) bring together history of science and philosophy of history for productive dialog.

    Objectives Furthering our understanding of the relationship between amyloidosis (Aβ), neurodegeneration (ND), and cognition is imperative for early identification and early intervention of Alzheimer’s disease (AD). However, the subtle cognitive decline differentially associated with each biomarker-defined stage of preclinical AD has yet to be fully characterized. Recent work indicates that different components of memory performance (free and cued recall) may be differentially specific to memory decline in prodromal AD. We sought to examine the relationship between free and cued recall paradigms, in addition to global composites of memory, executive functioning, and processing speed in relation to stages of preclinical AD. Methods A total of 260 clinically normal (CN) older adults (CDR=0) from the Harvard Aging Brain study were grouped according to preclinical AD stages including Stage 0 (Aβ−/ND−), Stage 1 (Aβ+/ND−), Stage 2 (Aβ+/ND+), and suspected non-Alzheimer’s associated pathology (SNAP; Aβ−/ND+). General linear models controlling for age, sex, and education were used to assess for stage-based performance differences on cognitive composites of executive functioning, processing speed, and memory in addition to free and cued delayed recall on the Selective Reminding Test (SRT) and Memory Capacity Test (MCT). Results Global memory performance differed between preclinical stages with Stage 2 performing worse compared with Stage 0. When examining free and cued paradigms by memory test, only the MCT (and not the SRT) revealed group differences. More specifically, Stage 1 was associated with decrements in free recall compared with Stage 0 while Stage 2 was associated with decrements in both free and cued recall. There was a trend for the SNAP group to perform worse on free recall compared with Stage 0. Finally, there was no association between preclinical stage and global composites of executive functioning or processing speed. Conclusions Clinically

  7. Approach to Investigating Congenital Skeletal Abnormalities in Livestock.

    2015-09-01

    Congenital skeletal abnormalities may be genetic, teratogenic, or nutritional in origin; distinguishing among these different causes is essential in the management of the disease but may be challenging. In some cases, teratogenic or nutritional causes of skeletal abnormalities may appear very similar to genetic causes. For example, chondrodysplasia associated with intrauterine zinc or manganese deficiency and mild forms of hereditary chondrodysplasia have very similar clinical features and histologic lesions. Therefore, historical data are essential in any attempt to distinguish genetic and acquired causes of skeletal lesions; as many animals as possible should be examined; and samples should be collected for future analysis, such as genetic testing. Acquired causes of defects often show substantial variation in presentation and may improve with time, while genetic causes frequently have a consistent presentation. If a disease is determined to be of genetic origin, a number of approaches may be used to detect mutations, each with advantages and disadvantages. These approaches include sequencing candidate genes, single-nucleotide polymorphism array with genomewide association studies, and exome or whole genome sequencing. Despite advances in technology and increased cost-effectiveness of these techniques, a good clinical history and description of the pathology and a reliable diagnosis are still key components of any investigation.

    We have evaluated 62 fragile X syndrome [fra(X)] individuals (55 males and 7 females) with different degrees of developmental disabilities that were clinically non-progressive and non-focal in character. The mean age for the 55 males was 23.1 years +/- 14.3 SD with a range of 2-70: for the 7 females, the mean age was 15.7 years +/- 3.5 SD with a range of 10-20 years. Mental retardation (MR) was found in 53 males (8/53 [15.1%] mild, 26/53 [49.1%] moderate, 14/53 [26.4%] severe, and 5/53 [9.4%] profound). Learning disabilities were found in 2/55 (3.6%) of males. One of the 7 females had mild and one had moderate MR: the other 5 were learning disabled. Autistic stigmata were present in 10/62 (16%) of the patients. Only 14/62 (23%) had a history of seizures, all of which were controlled with anticonvulsants. In 36/62 cases, an electroencephalogram (EEG) was performed. We compared these data with that of others. Brain stem auditory evoked response (BAER) was performed in 12 cases. Abnormalities were found in only 5/12. Neuroimaging and computerized cranial transaxial tomography (CT scan) were performed on 21/62 (34%) of the patients. Only 8 of these 21 (38%) studies were abnormal. One patient died; neuropathological studies showed mild brain atrophy, with light microscopic and ultrastructural abnormalities. Rapid Golgi dendritic spine patterns showed that the proximal apical segments were abnormally developed. Very thin, long tortuous spines with prominent terminal heads and irregular dilatations were present. Marked reductions in the length of the synapses, as determined on EPTA-postfixed tissue where noted.(ABSTRACT TRUNCATED AT 250 WORDS)

    Cytogenetic studies have an important role in the evaluation of couples with repeated miscarriages and poor obstetric history. To estimate the prevalence of chromosomal abnormalities and polymorphic variants in 158 couples with repeated miscarriages, a cross-sectional study was conducted in Monterrey, Mexico from 1995 to 2003. Peripheral blood lymphocytes were cultured for chromosomal studies using standard methods. Twelve couples showed chromosomal abnormalities (7.60%), two Robertsonian translocations (1.27%), two balanced translocations (1.27%), one inversion (0.63%), and one a novel insertion (0.63%). This insertion [46, XX, ins (15;8) (q26;p11p23)] is unique, and is the third reported in association with repeated abortion. Mosaicism was observed in six couples (3.80%, three with structural abnormalities and three with numerical abnormalities). A female to male ratio of 1.4:1 was observed. In addition to these chromosomal abnormalities, polymorphic variants in constitutive heterochromatin of the 1qh+, 9qh+, and 16qh+ chromosomes were observed in 25 couples (15.82%), of the Yqh+ chromosome in 21 couples (13.29%), and of satellite in 35 couples (22.15%). In conclusion, chromosome analysis is necessary for appropriate clinical management of these patients.

    BACKGROUND:Correlations between the structural abnormalities of chromosome 1pter in nasopharyngeal carcinoma(NPC) and its tumorigenesis and clinical significance are still unclear. OBJECTIVE: To investigate the correlations between the structural abnormalities of chromosome 1pter in NPC and the tumorigenesis of NPC. DESIGN:A retrospective study was performed to the control group according to the diagnosis. SETTING and PARTICIPANTS: The experiment was collected and completed in Reaearch Department of Sun Yat-Sen Cancer Center.Biopsy specimens from the nasopharynx of 65 cases of pathologically confirmed primary NPC without any therapy in the Sun Yat-Sen Univrsity Cancer Center were collected between the year 1998 and 2000 to survey. INTERVENTION: After the purification of cancerous cells from NPC biopsies with many noncancerous lymphocytes, interphase fluorescent in situ hybridization(FISH) and PCR-LOH/MI analysis of the somatic alterations of chromosomes 1pter in 65 cases of NPC biopsies were performed by using 1pter-related probe, TelVysion 1p, and telomere-linked microsatellite polymorphism site, D1S243,respectively. MAIN TOUCOME MEASURES: The abnormalities such as chromosome deletion, amplification and microsatellite instabilities(MI) and their clinical implications were examined and investigated. RESULTS:The somatic alterations of chromosome 1pter of NPC were detected in 20 of 65 cases with NPC, 8 of which showed allelic deletion,7 amplification and 5 both simultaneously.In available 44 patients with clinical stages, 2 of the 4 NPC cases in the early clinical stage were proved to be aberrations in chromosome 1pter, whereas 30.0% (12/40) of NPC patients in advanced clinical stage showed somatic structural aberrations of chromosome 1pter(χ 2=0.0655,P >0.05).PCR-LOH/MI analysis indicated that, out of the matched 31 NPC biopsies,16 had detectable aberrations, including 13 microsatellite instability(MI),2 homozygous deletion(HD) and 1 loss of heterozygosity

    Full Text Available Objective. To assess the neuroradiological findings of children with congenital hypothyroidism (CHT compared to healthy controls (HC. Patients and Methods. Thirty children with CHT, mean age 12.5 ± 1.6 years, 14 (44.8% males, were compared with 38 HC mean age 11.7 ± 1.7 years, 16 (45.7% males. Clinical data were collected from medical charts and questionnaires seeking information on family history, birth and perinatal period events, medications, and overall health history. Neurocognitive function was assessed for global intelligence, visual and verbal memory, and executive functioning using standardized tests. Neuroimaging was performed using 1.5 T magnetic resonance imaging and assessed by two pediatric radiologists. Results. Children with CHT had a similar proportion of incidental findings as did the children in the HC group, at 43.3% and 39.5%, respectively, . Abnormalities of the sellar region were reported in 13.3% of CHT group and 7.9% of HC group, . Other incidental findings included cerebellar ectopia, choroidal fissure and pineal cysts, and multiple increased signal intensity foci. Neuroradiological findings were not associated with clinical and neurocognitive abnormalities. Conclusion. Neuroimaging of children with CHT demonstrated a similar incidence of structural abnormalities as in the healthy population. There is no association between those findings and neurocognitive function.

    In the assessment of chest pain patients with suspected acute coronary syndrome (ACS) in the emergency department (ED), physicians rely on global diagnostic impressions ('gestalt'). The aim of this study was to determine the diagnostic value of the ED physician's overall assessment of ACS likelihood, and the values of the main diagnostic modalities underlying this assessment, namely the chest pain history, the ECG and the initial troponin result. 1,151 consecutive ED chest pain patients were prospectively included. The ED physician's interpretation of the chest pain history, the ECG, and the global likelihood of ACS were recorded on special forms. The discharge diagnoses were retrieved from the medical records. A chart review was carried out to determine whether patients with a non-ACS diagnosis at the index visit had ACS or suffered cardiac death within 30 days. The gestalt was better than its components both at ruling in ("Obvious ACS", LR 29) and at ruling out ("No Suspicion of ACS", LR 0.01) ACS. In the "Strong suspicion of ACS" group, 60% of the patients did not have ACS. A positive TnT (LR 24.9) and an ischemic ECG (LR 8.3) were strong predictors of ACS and seemed superior to pain history for ruling in ACS. In patients with a normal TnT and non-ischemic ECG, chest pain history typical of AMI was not a significant predictor of AMI (LR 1.9) while pain history typical of unstable angina (UA) was a moderate predictor of UA (LR 4.7). Clinical gestalt was better than its components both at ruling in and at ruling out ACS, but overestimated the likelihood of ACS when cases were assessed as strong suspicion of ACS. Among the components of the gestalt, TnT and ECG were superior to the chest pain history for ruling in ACS, while pain history was superior for ruling out ACS.

    Full Text Available Homeobox genes are essential for both the development of the blood and lymphatic vascular systems, as well as for their maintenance in the adult. Homeobox genes comprise an important family of transcription factors, which are characterised by a well conserved DNA binding motif; the homeodomain. The specificity of the homeodomain allows the transcription factor to bind to the promoter regions of batteries of target genes and thereby regulates their expression. Target genes identified for homeodomain proteins have been shown to control fundamental cell processes such as proliferation, differentiation and apoptosis. We and others have reported that homeobox genes are expressed in the placental vasculature, but our knowledge of their downstream target genes is limited. This review highlights the importance of studying the cellular and molecular mechanisms by which homeobox genes and their downstream targets may regulate important vascular cellular processes such as proliferation, migration, and endothelial tube formation, which are essential for placental vasculogenesis and angiogenesis. A better understanding of the molecular targets of homeobox genes may lead to new therapies for aberrant angiogenesis associated with clinically important pregnancy pathologies, including fetal growth restriction and preeclampsia.

    Full Text Available Chromosomal abnormalities are among the most common genetic causes of spermatogenic disruptions. Carriers of chromosomal abnormalities are at increased risk of infertility, miscarriage or birth of a child with unbalanced karyotype due to the production of unbalanced gametes. The natural selection against chromosomally abnormal sperm usually prevents fertilization with sperm barring in cases of serious chromosomal abnormalities. However, assisted reproductive technologies in general and intracytoplasmic sperm injection in particular, enable the transmission of chromosomal abnormalities to the progeny. Therefore, cytogenetic studies are important in patients with male factor infertility before assisted reproduction treatment. The purpose of the current study was to investigate the types and frequencies of chromosomal abnormalities in 724 patients with infertility and to estimate the risk of chromosomal abnormalities detection in subgroups of patients depending on the severity of spermatogenic disruption, aiming at identifying groups of patients in need of cytogenetic studies. Karyotype analysis was performed in 724 blood samples of men attending infertility clinic. Chromosomal preparation was performed by standard techniques. At least 20 GTG-banded metaphase plates with the resolution from 450 to 750 bands per haploid set were analysed in each case. When chromosomal mosaicism was suspected, this number was increased to 50. Abnormal karyotypes were observed in 48 (6.6% patients, including 67% of autosomal abnormalities and 33% of gonosomal abnormalities. Autosomal abnormalities were represented by structural rearrangements. Reciprocal translocations were the most common type of structural chromosomal abnormalities in the studied group, detected with the frequency of 2.6% (n = 19, followed by Robertsonian translocation, observed with the frequency of 1.2% (n = 9. The frequency of inversions was 0.6% (n = 4. Gonosomal abnormalities included 14 cases

    Full Text Available Objective: Differentiating asthma from chronic obstructive pulmonary disease (COPD is difficult. Steroid trial may be of help but has several pitfalls. The present study aims to assess the value of past clinical profile of asthma and its differential diagnosis from COPD in male smokers and thereby to formulate clinical parameters to diagnose bronchial asthma in such patients. Patients and Methods: Male smokers who reported at the Respiratory Medicine Department of the National Institute of Medical Sciences (NIMS Hospital, Jaipur, (India, with shortness of breath (SOB and showing less than 12% postbronchodilator bronchial reversibility (BR on spirometry were recruited. These patients were given oral prednisolone 1 mg/kg for two weeks. Post steroid (PS spirometry was performed to ascertain BR. The past clinical history was recorded and analyzed to determine if it is of any use in differentiating asthma from COPD. Result: Out of 104 patients, four were lost to follow up, 52 were diagnosed as bronchial asthma, and the remaining 48 as COPD. It was revealed that past history of (H/O seasonal variation, wheezing, eye allergy, nasal allergy, dust allergy, skin allergy, and family H/O asthma/allergy were positive in 50, 40, 34, 30, 18, 14, and 12 asthma patients as compared to 10, 8, 2, 4, 6, 0, and 0 in 48 COPD patients (P < 0.001. The odds ratio (OR for diagnosing asthma was highest for the presence of any other two symptoms/variables, besides SOB, in the past (OR = 275, P < 0.0001. Conclusion: Past clinical history is of immense value in differentiating asthma from COPD in male smokers presenting with SOB and fixed airway obstruction.

  15. Chromosomal phenotypes and submicroscopic abnormalities

    Devriendt Koen

    2004-01-01

    Full Text Available Abstract The finding, during the last decade, that several common, clinically delineated syndromes are caused by submicroscopic deletions or, more rarely, by duplications, has provided a powerful tool in the annotation of the human genome. Since most microdeletion/microduplication syndromes are defined by a common deleted/duplicated region, abnormal dosage of genes located within these regions can explain the phenotypic similarities among individuals with a specific syndrome. As such, they provide a unique resource towards the genetic dissection of complex phenotypes such as congenital heart defects, mental and growth retardation and abnormal behaviour. In addition, the study of phenotypic differences in individuals with the same microdeletion syndrome may also become a treasury for the identification of modifying factors for complex phenotypes. The molecular analysis of these chromosomal anomalies has led to a growing understanding of their mechanisms of origin. Novel tools to uncover additional submicroscopic chromosomal anomalies at a higher resolution and higher speed, as well as the novel tools at hand for deciphering the modifying factors and epistatic interactors, are 'on the doorstep' and will, besides their obvious diagnostic role, play a pivotal role in the genetic dissection of complex phenotypes.

    Bowel rotation abnormalities in heterotaxy are common. As more children survive cardiac surgery, the management of gastrointestinal abnormalities has become controversial. To evaluate imaging of malrotation in heterotaxy with surgical correlation and provide an algorithm for management. Imaging reports of heterotaxic children with upper gastrointestinal (UGI) and/or small bowel follow-through (SBFT) were reviewed. Subsequently, fluoroscopic images were re-reviewed in conjunction with CT/MR studies. The original reports and re-reviewed images were compared and correlated with surgical findings. Nineteen of 34 children with heterotaxy underwent UGI, 13/19 also had SBFT. In 15/19 reports, bowel rotation was called abnormal: 11 malrotation, 4 non-rotation, no cases of volvulus. Re-review, including CT (10/19) and MR (2/19), designated 17/19 (90%) as abnormal, 10 malrotation (abnormal bowel arrangement, narrow or uncertain length of mesentery) and 7 non-rotation (small bowel and colon on opposite sides plus low cecum with probable broad mesentery). The most useful CT/MR findings were absence of retroperitoneal duodenum in most abnormal cases and location of bowel, especially cecum. Abnormal orientation of mesenteric vessels suggested malrotation but was not universal. Nine children had elective bowel surgery; non-rotation was found in 4/9 and malrotation was found in 5/9, with discrepancies (non-rotation at surgery, malrotation on imaging) with 4 original interpretations and 1 re-review. We recommend routine, early UGI and SBFT studies once other, urgent clinical concerns have been stabilized, with elective laparoscopic surgery in abnormal or equivocal cases. Cross-sectional imaging, usually obtained for other reasons, can contribute diagnostically. Attempting to assess mesenteric width is important in differentiating non-rotation from malrotation and more accurately identifies appropriate surgical candidates. (orig.)

  3. Defining natural history: assessment of the ability of college students to aid in characterizing clinical progression of Niemann-Pick disease, type C.

    Jenny Shin

    Full Text Available Niemann-Pick Disease, type C (NPC is a fatal, neurodegenerative, lysosomal storage disorder. It is a rare disease with broad phenotypic spectrum and variable age of onset. These issues make it difficult to develop a universally accepted clinical outcome measure to assess urgently needed therapies. To this end, clinical investigators have defined emerging, disease severity scales. The average time from initial symptom to diagnosis is approximately 4 years. Further, some patients may not travel to specialized clinical centers even after diagnosis. We were therefore interested in investigating whether appropriately trained, community-based assessment of patient records could assist in defining disease progression using clinical severity scores. In this study we evolved a secure, step wise process to show that pre-existing medical records may be correctly assessed by non-clinical practitioners trained to quantify disease progression. Sixty-four undergraduate students at the University of Notre Dame were expertly trained in clinical disease assessment and recognition of major and minor symptoms of NPC. Seven clinical records, randomly selected from a total of thirty seven used to establish a leading clinical severity scale, were correctly assessed to show expected characteristics of linear disease progression. Student assessment of two new records donated by NPC families to our study also revealed linear progression of disease, but both showed accelerated disease progression, relative to the current severity scale, especially at the later stages. Together, these data suggest that college students may be trained in assessment of patient records, and thus provide insight into the natural history of a disease.

    Full Text Available OBJECTIVE To determine the frequency and types of craniofacial abnormalities observed in patients with trisomy 18 or Edwards syndrome (ES. METHODS This descriptive and retrospective study of a case series included all patients diagnosed with ES in a Clinical Genetics Service of a reference hospital in Southern Brazil from 1975 to 2008. The results of the karyotypic analysis, along with clinical data, were collected from medical records. RESULTS: The sample consisted of 50 patients, of which 66% were female. The median age at first evaluation was 14 days. Regarding the karyotypes, full trisomy of chromosome 18 was the main alteration (90%. Mosaicism was observed in 10%. The main craniofacial abnormalities were: microretrognathia (76%, abnormalities of the ear helix/dysplastic ears (70%, prominent occiput (52%, posteriorly rotated (46% and low set ears (44%, and short palpebral fissures/blepharophimosis (46%. Other uncommon - but relevant - abnormalities included: microtia (18%, orofacial clefts (12%, preauricular tags (10%, facial palsy (4%, encephalocele (4%, absence of external auditory canal (2% and asymmetric face (2%. One patient had an initial suspicion of oculo-auriculo-vertebral spectrum (OAVS or Goldenhar syndrome. CONCLUSIONS: Despite the literature description of a characteristic clinical presentation for ES, craniofacial alterations may be variable among these patients. The OAVS findings in this sample are noteworthy. The association of ES with OAVS has been reported once in the literature.

    Hyperhomocysteinemia and abnormal blood lipids are independent risk factors for stroke. However, whether both factors exert a synergistic effect in the onset of stroke remains unclear. The present study is a retrospective analysis of 2 089 cases of stroke and 2 089 control cases of simple inter-vertebral disk protrusion using a paired multivariate logistic regression method. Adjusting for known confounding variables including the patients’ age, gender, smoking status, alcohol consumption status, patient and family medical history, and clinical biochemical indices, elevated homocysteine level was related to the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids showed a 40.9%increase in the risk for stroke compared to patients with normal ho-mocysteine levels and blood lipids (odds ratio 1.409;95%confidence interval 1.127-1.761). These results indicate that elevated homocysteine and abnormal blood lipids exert synergistic effects in the onset of stroke. Patients with elevated homocysteine levels and abnormal blood lipids are predis-posed to stroke.

This systematic review presents a synthesis of the available literature, which examined the association between dental fear and a history of sexual violence victimisation. All studies indicated, to various degrees, that dental fear is associated with a history of sexual violence victimisation. The analysis identified several common themes including a perception of lack of control, avoidance behaviours, experiences of flashbacks, feelings of embarrassment, difficulties with the physical proximity to the dentist, the sex of the dentist reminding patients of the perpetrator, being placed into a horizontal body position, the specific impact of fellatio, the smell of latex, experienced lack of knowledge of dental professionals leading to insensitive treatment as well as revictimisation experiences, and the occurrence of disproportionate dental problems among patients who had experienced event(s of sexual violence. All these themes are discussed in detail. Specific strategies are offered to assist dental practitioners in providing sensitive treatment for patients with a history of sexual violence.

    Sonoluminescence is a complex phenomenon, the mechanism of which remains unclear. The present study reveals that an abnormal ionization process is likely to be present in the sonoluminescing bubble. To fit the experimental data of previous studies, we assume that the ionization energies of the molecules and atoms in the bubble decrease as the gas density increases and that the decrease of the ionization energy reaches about 60%-70% as the bubble flashes, which is difficult to explain by using previous models.

    Multicolor FISH has been adapted for detecting the major types of chromosomal abnormalities in human sperm including aneuploidies for clinically-relevant chromosomes, chromosomal aberrations including breaks and rearrangements, and other numerical abnormalities. The various sperm FISH assays have been used to evaluate healthy men, men of advanced age, and men who have received mutagenic cancer therapy. The mouse has also been used as a model to investigate the mechanism of paternally transmitted genetic damage. Sperm FISH for the mouse has been used to detect chromosomally abnormal mouse sperm, while the PAINT/DAPI analysis of mouse zygotes has been used to evaluate the types of chromosomal defects that can be paternally transmitted to the embryo and their effects on embryonic development.

    Personal and family health histories remain important independent risk factors for cancer; however they are currently not being well collected or used effectively. Health Heritage was designed to address this need. The purpose of this study was to validate the ability of Health Heritage to identify patients appropriate for further genetic evaluation and to accurately stratify cancer risk. A retrospective chart review was conducted on 100 random patients seen at an adult genetics clinic presenting with concern for an inherited predisposition to cancer. Relevant personal and family history obtained from the patients' medical records was entered into Health Heritage. Recommendations by Health Heritage were compared to national guidelines of eligibility for genetic evaluation. Agreement between Health Heritage referral for genetic evaluation and guideline eligibility for genetic evaluation was 97% (sensitivity 98% and specificity 88%). Risk stratification for cancer was also compared between Health Heritage and those documented by a geneticist. For patients at increased risk for breast, ovarian, or colorectal cancer as determined by the geneticist, risk stratification by Health Heritage agreed 90, 93, and 75%, respectively. Discordances in risk stratification were attributed to both complex situations better handled by the geneticist and Health Heritage's adherence to incorporating all information into its algorithms. Health Heritage is a clinically valid tool to identify patients appropriate for further genetic evaluation and to encourage them to confirm the assessment and management recommendations with cancer genetic experts. Health Heritage also provides an estimate of cancer risk that is complementary to a genetics team.

Objectives: The primary educational objective of this program was to formally introduce medical students to clinical procedures thought to be important for success in residency. The immersion strategy (teaching numerous procedures over a 7-day period was intended to complement the student's education on third-year core clinical clerkships. Program design: The course introduced 27 skills over 7 days. Teaching and learning methods included lecture, prereading, videos, task trainers, peer teaching, and procedures practice on cadavers. In year 4 of the program, a peer-team teaching model was adopted. We analyzed program evaluation data over time. Impact: Students valued the selection of procedures covered by the course and felt that it helped prepare them for residency (97%. The highest rated activities were the cadaver lab and the advanced cardiac life support (97 and 93% positive endorsement, respectively. Lectures were less well received (73% positive endorsement, but improved over time. The transition to peer-team teaching resulted in improved student ratings of course activities (p<0.001. Conclusion: A dedicated procedural skills curriculum successfully supplemented the training medical students received in the clinical setting. Students appreciated hands-on activities and practice. The peer-teaching model improved course evaluations by students, which implies that this was an effective teaching method for adult learners. This course was recently expanded and restructured to place the learning closer to the clinical settings in which skills are applied.

    We will study the epidemiologic, clinical, biological, therapeutic, prognostic characteristics and predictive factors of development of nephropathy in ankylosing spondylitis patients. We retrospectively reviewed the medical record of 32 cases with renal involvement among 212 cases of ankylosing spondylitis followed in our service during the period spread out between 1978 and 2006. The renal involvement occurred in all patients a mean of 12 years after the clinical onset of the rheumatic disease. Thirty-two patients presented one or more signs of renal involvement: microscopic hematuria in 22 patients, proteinuria in 23 patients, nephrotic syndrome in 11 patients and decreased renal function in 24 patients (75%). Secondary renal amyloidosis (13 patients), which corresponds to a prevalence of 6,1% and tubulointerstitial nephropathy (7 patients) were the most common cause of renal involvement in ankylosing spondylitis followed by IgA nephropathy (4 patients). Seventeen patients evolved to the end stage renal disease after an average time of 29.8 ± 46 months. The average follow-up of the patients was 4,4 years. By comparing the 32 patients presenting a SPA and renal disease to 88 with SPA and without nephropathy, we detected the predictive factors of occurred of nephropathy: tobacco, intense inflammatory syndrome, sacroileite stage 3 or 4 and presence of column bamboo. The finding of 75% of the patients presented a renal failure at the time of the diagnosis of renal involvement suggests that evidence of renal abnormality involvement should be actively sought in this disease.

    Nonautoimmune ketosis-prone diabetic syndromes are increasingly frequent in nonwhite populations. We have characterized a cohort of patients of sub-Saharan African origin who had ketosis-prone type 2 diabetes (n = 111), type 1 diabetes (n = 21), and type 2 diabetes (n = 88) and were admitted to a hospital for management of uncontrolled diabetes. We compared epidemiological, clinical, and metabolic features at diabetes onset and measured insulin secretion (glucagon-stimulated C-peptide) and insulin action (short intravenous insulin tolerance test) during a 10-year follow-up. Ketosis-prone type 2 diabetes shows a strong male predominance, stronger family history, higher age and BMI, and more severe metabolic decompensation than type 1 diabetes. In ketosis-prone type 2 diabetes, discontinuation of insulin therapy with development of remission of insulin dependence is achieved in 76% of patients (non-insulin dependent), whereas only 24% of patients remain insulin dependent. During evolution, ketosis-prone type 2 diabetes exhibit specific beta-cell dysfunction features that distinguish it from type 1 and type 2 diabetes. The clinical course of non-insulin-dependent ketosis-prone type 2 diabetes is characterized by ketotic relapses followed or not by a new remission. Progressive hyperglycemia precedes and is a strong risk factor for ketotic relapses (hazard ratio 38). The probability for non-insulin-dependent ketosis-prone type 2 diabetes to relapse is 90% within 10 years, of whom approximately 50% will become definitively insulin dependent. Insulin sensitivity is decreased in equal proportion in both ketosis-prone type 2 diabetes and type 2 diabetes, but improves significantly in non-insulin-dependent ketosis-prone type 2 diabetes, only after correction of hyperglycemia. In conclusion, ketosis-prone type 2 diabetes can be distinguished from type 1 diabetes and classical type 2 diabetes by specific features of clinical pathophysiology and also by the natural history of

    Current criteria identifying patients with ultra-high risk of psychosis (UHR) have low specificity, and less than one-third of UHR cases experience transition to psychosis within 3 years of initial assessment. We explored whether a Bayesian probabilistic multimodal model, combining baseline historical and clinical risk factors with biomarkers (oxidative stress, cell membrane fatty acids, resting quantitative electroencephalography (qEEG)), could improve this specificity. We analyzed data of a UHR cohort (n=40) with a 1-year transition rate of 28%. Positive and negative likelihood ratios were calculated for predictor variables with statistically significant receiver operating characteristic curves (ROCs), which excluded oxidative stress markers and qEEG parameters as significant predictors of transition. We clustered significant variables into historical (history of drug use), clinical (Positive and Negative Symptoms Scale positive, negative and general scores and Global Assessment of Function) and biomarker (total omega-3, nervonic acid) groups, and calculated the post-test probability of transition for each group and for group combinations using the odds ratio form of Bayes' rule. Combination of the three variable groups vastly improved the specificity of prediction (area under ROC=0.919, sensitivity=72.73%, specificity=96.43%). In this sample, our model identified over 70% of UHR patients who transitioned within 1 year, compared with 28% identified by standard UHR criteria. The model classified 77% of cases as very high or low risk (P>0.9, <0.1) based on history and clinical assessment, suggesting that a staged approach could be most efficient, reserving fatty-acid markers for 23% of cases remaining at intermediate probability following bedside interview.

    CT bilaterally showed a cold area in the putamen of 5 infants with cerebral palsy who had had asphyxia at birth. The etiology was discussed, and 4 of the cases were clinically studied. All four patients had convulsive tetraplegia, or convulsive bilateral paralysis with the element of athetosis. Three of them had a history of infantile epilepsy, accompanied by abnormal ocular movement. Two patients with tetraplegia showed marked hypotonia of the trunk in ventral support (Landau). Impairment of the bilateral putamens in the abnormal muscle tone was inferred.

    Establishing the role of heredity in type 2 diabetes mellitus (type 2 DM) is challenging. While type 2 DM frequently displays a pattern of familial aggregation, many other risk factors are responsible for the clinical expression of the disease. This paper reviews a number of the early twentieth-century studies of inheritance patterns for type 2 DM and presents in detail the history of Josephine Foniciello Imperato (Maria Giuseppa Foniciello) who died from the disease in New York City at the age of 52 years on 14 November 1921, ten months before commercial insulin became available.

  6. A Rare Stapes Abnormality

    Full Text Available The aim of this study is to increase awareness of rare presentations, diagnostic difficulties alongside management of conductive hearing loss and ossicular abnormalities. We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and lack of connection between the stapes superstructure and footplate. The footplate was fixed. Stapedotomy and stapes prosthesis insertion resulted in closure of the air-bone gap by 50 dB. A review of world literature was performed using MedLine. Middle ear ossicular discontinuity can result in significant conductive hearing loss. This can be managed effectively with surgery to help restore hearing. However, some patients may not be suitable or decline surgical intervention and can be managed safely conservatively.

    We employed neurolinguistic programming (NLP) principles to develop a positive self-identity in an elderly male patient in England recovering from clinical depression. This novel technique encouraged recall of intrinsically rewarding past experiences. Each experience was conceptualized in an image and compiled chronologically in an imaginary book, providing continuity to what were chaotic and fragmented recollections during the immediate postdepressive stage. The patient's anxiety and depression were alleviated and his own functional goals largely realized.

    PURPOSE OF REVIEW: The aim is to provide an overview of recent studies of structural brain abnormalities in migraine and to discuss the potential clinical significance of their findings. RECENT FINDINGS: Brain structure continues to be a topic of extensive research in migraine. Despite advances...... in neuroimaging techniques, it is not yet clear if migraine is associated with grey matter changes. Recent large population-based studies sustain the notion of increased prevalence of white matter abnormalities in migraine, and possibly of silent infarct-like lesions. The clinical relevance of this association...... is not clear. Structural changes are not related to cognitive decline, but a link to an increased risk of stroke, especially in patients with aura, cannot be ruled out. SUMMARY: Migraine may be a risk factor for structural changes in the brain. It is not yet clear how factors such as migraine sub-type, attack...

    Objective To evaluate the clinical effects and clinical classification of occlusal rehabilitation in elderly patients with abnormal occlusion, and to discuss the diagnosis principles and the practical techniques of the dental prosthesis for occlusal rehabilitation. Methods Forty two elderly patients with abnormal occlusion were treated with occlusal rehabilitation with fixed dentures, fixed-removable dentures and removable partial dentures. Eight patients among them simultaneously had temporomandibular joint(TMJ) disorder. After the clinical procedures including examination, diagnosis, prosthesis design, manufacture, application of occlusal rehabilitation and post-treatment evaluation, the using condition of dentures, patients' satisfaction ratings, TMJ functions and abutment teeth healthy status were examined before and after treatment. Results All the patients were satisfied with their dentures' general functions 1 year after treatment. Compared with the removable partial dentures, the other two types of prosthesis showed better clinical outcomes (χ2=4.15,P<0.05) and compacts on phonation of the dentures (χ2=4.71,P<0.05). In the 8 patients with TMJ disorder, 7 cases were cured completely. The treatment effects of TMJ pain (χ2=0.031, P<0.05)and TMJ click (χ2=0.038, P<0.05)had statistical differences. 30 teeth of the 203 abutment teeth (14.8%) had the problems of periodontal diseases and secondary caries and the incidences of these problems were higher in using removable partial dentures treatment than in the other two methods. Conclusions After the systematic diagnosis and the prosthesis design procedures of occlusal rehabilitation, it is important to choose a proper prostheses for the elderly patients according to their physical and psychological features, which may give the patients satisfactory results.%目的 评价不同种类咬合重建修复的临床效果,探讨老年咬合异常患者咬合重建的临床分类、诊断

    Background: Syncope is a relevant health problem in military environments. Reliable diagnosis is challenging. Tilt table testing is an important tool for syncope diagnosis. The aim of this study was to determine whether signs such as prodromal symptoms, co-morbidity, frequency of syncopal events, body length, body mass index, and electrocardiography (ECG) abnormalities can be used to predict the success of tilt table testing at diagnosing syncope. Methods: Data from 100 patients with histories of syncope or pre-syncope, who were diagnosed using head-up tilt table testing, were retrospectively analyzed in a cross-sectional analysis. The diagnostic procedure was based upon a modified version of the Westminster protocol without any pharmacological provocation. Results: Patients showing pathological reaction patterns during tilt table testing suffered from prodromal symptoms, such as dizziness and sweating, significantly more often. The patients reported more injuries resulting from syncopal events and more previous syncopal events, and the prevalence of co-morbidity was greater among patients presenting negative findings during tilt testing. An asthenic-leptosomal physique was not confirmed as a risk factor for syncopal events as is the case for idiopathic arterial hypotension. However, patients with pathological reaction patterns during tilt table testing were significantly taller. This finding was detected for both females and males. No significant predictors were found in the ECG patterns of patients showing syncope during tilt table testing. Conclusions: Frequency of prior syncope and prodromal symptoms, and increased body length with an otherwise good state of health influence the predictive value of tilt table testing for syncope diagnosis. In particular, if these factors are present, tilt table testing should be considered part of the diagnostic algorithm for soldiers with recurrent syncope.

    Objective: To study the influence of mechanical stimulation on IVF-ET clinical outcome. Methods: In the cycle of in vitro fertilization-embryo transfer (IVF-ET), 63 patients were studied who were with abnormal endometrial echoes by ultrasound in follicular phase in natural period. They were devided into two groups: 30 patients (experimental group) were mechanical stimulated to the endometrium during 1-2 weeks before embryo transfer. The remaining 33 patients (control group) were not treated. Results: There were no statistical differences between the two groups on the dose of Gn use, the impact of serum progesterone / estratiol ratio on hCG administration day, the number of oocytes retrieved, the rate of fertilization and the number of good embryos transferred (P>0.05). After mechanical stimulation to the endometrium, endometrial pattern, endometrial and subendometrial blood flows on the day of hCG administration were improved than those of the control (P<0.01). Embryo implantion rate, clinical pregnancy rate were significantly improved, while early spontaneous abortion rate was delated than that in the control (P<0.0l). Conclusion: Mechanical stimulation to the endometrium significantly improves the rates of embryo implantation, clinical pregnancy in patients undergoing in vitro fertilization while decrease the rate of early spontaneous abortion perhaps through affecting endometrial and subendometrial blood flows.%目的:探讨机械刺激子宫内膜对临床结局的影响及机制.方法:选取行体外受精-胚胎移植(IVF-ET)且其自然月经周期卵泡晚期超声提示子宫内膜形态不良的不育患者63例,随机分为研究组(n=30)和对照组(n=33).研究组在胚胎移植前1~2周对子宫内膜行机械刺激,对照组未行机械刺激为,统计分析IVF-ET的临床结局.结果:Gn用量、hCG注射日P/E2值、平均获卵数、受精率及移植优质胚胎数组间无统计学差异(P>0.05);研究组子宫内膜形态及子宫内膜

  14. Communication and abnormal behaviour.

    Crown, S

    1979-01-01

    In this paper the similarities between normal and abnormal behaviour are emphasized and selected aspects of communication, normal and aberrant, between persons are explored. Communication in a social system may be verbal or non-verbal: one person's actions cause a response in another person. This response may be cognitive, behavioural or physiological. Communication may be approached through the individual, the social situation or social interaction. Psychoanalysis approaches the individual in terms of the coded communications of psychoneurotic symptoms or psychotic behaviour; the humanist-existential approach is concerned more with emotional expression. Both approaches emphasize the development of individual identity. The interaction between persons and their social background is stressed. Relevant are sociological concepts such as illness behaviour, stigma, labelling, institutionalization and compliance. Two approaches to social interactions are considered: the gamesplaying metaphor, e.g. back pain as a psychosocial manipulation--the 'pain game'; and the 'spiral of reciprocal perspectives' which emphasizes the interactional complexities of social perceptions. Communicatory aspects of psychological treatments are noted: learning a particular metaphor such as 'resolution' of the problem (psychotherapy), learning more 'rewarding' behaviour (learning theory) or learning authenticity or self-actualization (humanist-existential).

    BACKGROUND: Congenital scoliosis occurs because of either the failure of formation or the failure of segmentation or both. Evaluation of the incidence and the types of occult intraspinal abnormalities in congenital scoliosis is the subject of this study.

    METHODS: During a period of 29 years, 103 patients with congenital scoliosis were studied. MRI was used in 46 patients, myelography or CT myelography was used in 64 patients and both MRI and myelography or CT myelography were used in 7 patients for intraspinal abnormalities.

    RESULTS: In the MRI group, among the 46 patients, 19 patients (41.3% had intraspinal abnormalities consisting syringomyelia in 9 (19.5% diastematomyelia in 8 (17.4%, tethered cord syndrome in 6 (13%, low conus in 5 (10.8% and diplomyelia in 3 (6.5% of the patients. In the myelography group, among the 64 patients, 17 (26.5% had intraspinal abnormalities and diastematomyelia was the most common one found in 14 (21.8% patients.

    CONCLUSIONS: Intraspinal abnormalities are frequent in congenital scoliosis. Syringomyelia may be associated with congenital scoliosis. In congenital scoliosis, rib fusion may be an indicator of intraspinal abnormalities in MRI. A significant difference between clinical findings and intraspinal anomalies (P<0.05 was noted. Moreover, we believe that total spinal MRI with coronal, sagittal and axial views is a valuable tool in determining the intraspinal abnormalities in congenital scoliosis. This method is highly

    Science.gov (United States)

    2015-01-01

    Despite decades of widespread use, the adverse effect profile of "selective" serotonin reuptake inhibitor (SSRI) antidepressants has still not been fully elucidated. Studies in male animals have shown delayed sexual development and reduced fertility. Three prospective cohort studies conducted in over one hundred patients exposed to an SSRI for periods ranging from 5 weeks to 24 months found altered semen param-eters after as little as 3 months of exposure: reduced sperm concentration, reduced sperm motility, a higher percentage of abnormal spermatozoa, and increased levels of sperm DNA fragmentation. One clinical trial showed growth retardation in children considered depressed who were exposed to SSRls. SSRls may have endocrine disrupting properties. Dapoxetine is a short-acting serotonin reuptake inhibitor that is chemically related to fluoxetine and marketed in the European Union for men complaining of premature ejaculation. But the corresponding European summary of product characteristics does not mention any effects on fertility. In practice, based on the data available as of mid-2014, the effects of SSRI exposure on male fertility are unclear. However, it is a risk that should be taken into account and pointed out to male patients who would like to father a child or who are experiencing fertility problems.

    Full Text Available In this study, 44 patients with liver cirrhosis were investigated for hemostatic parameters. Patients with spontaneous bacterial peritonitis, hepatocellular carcinoma, hepatorenal syndrome and cholestatic liver diseases were excluded. Patients were classified by Child-Pugh criterion and according to this 4 patients were in Class A, 20 in Class B and 20 in C. Regarding to these results, it was aimed to investigate the haematological disturbances in liver cirrhotic patients.In the result there was a correlation between activated partial thromboplastin time, serum iron, ferritin, transferrin, haptoglobin and Child-Pugh classification. Besides there was no correlation between prothrombin time, factor 8 and 9, protein C and S, anti-thrombin 3, fibrinogen, fibrin degradation products, serum iron binding capacity, hemoglobin, leukocyte, mean corpuscular volume and Child-Pugh classification.There were significant difference, in terms of AST, ferritin, haptoglobulin, sex and presence of ascites between groups (p0.05. In the summary, we have found correlation between hemostatic abnormalities and disease activity and clinical prognosis in patients with liver cirrhosis which is important in the management of these patients. This is also important for identification of liver transplant candidiates earlier.

    Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophagealmotility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from nonerosive reflux disease to erosive reflux disease and Barrett’s esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett's esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted.

    Introduction Chromosomal abnormalities are the results of alterations in the number or structure of chromosomes causing significant human morbidity and mortality. They are responsible for a large proportion of miscarriages, developmental delay, disorders of sexual development, congenital malformations and mental retardation. Aim The aim of this study was to describe the prevalence of different chromosomal abnormalities in North Indian patients referred for cytogenetic analysis. Materials and Methods Total of 859 patients ranging from newborn to 37 years of age were referred to the division of genetics, Department of Paediatrics between 2010 and 2015, with a variety of clinical disorders; Down syndrome (DS), Turner’s syndrome (TS) and Klinefelter syndrome; amenorrhea; ambiguous sex and multiple congenital malformations. Chromosomal analysis was performed on lymphocyte culture according to standard methods. Results Of the 859 cases studied, 371 (43.1%) had chromosomal abnormalities. The most common autosomal abnormalities were DS 302 (81.4%) and sex chromosomal abnormalities were TS 51 (13.7%). Numerical abnormalities were accounted for 353 (41.0%) and structural abnormalities 18 (2.0%), respectively. Various other chromosomal anomalies were also reported. Conclusion We have reviewed the incidence and distribution of chromosomal abnormalities and found higher rate of chromosomal abnormalities 43.1% in the referred cases. Our data suggest that chromosomal analysis is important tool in the evaluation of genetic disorders and helps clinicians to provide accurate diagnosis and proper genetic counselling. PMID:27790464

    Systemic abnormalities often occur in patients with liver disease. In particular, cardiopulmonary or renal diseases accompanied by advanced liver disease can be serious and may determine the quality of life and prognosis of patients. Therefore, both hepatologists and non-hepatologists should pay attention to such abnormalities in the management of patients with liver diseases.

    IMPORTANCE Establishing the natural history of G11778A Leber hereditary optic neuropathy (LHON) is important to determine the optimal end points to assess the safety and efficacy of a planned gene therapy trial. OBJECTIVE To use the results of the present natural history study of patients with G11778A LHON to plan a gene therapy clinical trial that will use allotopic expression by delivering a normal nuclear-encoded ND4 gene into the nuclei of retinal ganglion cells via an adeno-associated virus vector injected into the vitreous. DESIGN, SETTING, AND PARTICIPANTS A prospective observational study initiated in 2008 was conducted in primary and referral institutional practice settings. Participants included 44 individuals with G11778A LHON, recruited between September 2008 and March 2012, who were evaluated every 6 months and returned for 1 or more follow-up visits (6-36 months) as of August 2012. EXPOSURES Complete neuro-ophthalmic examination and main measures. MAIN OUTCOMES AND MEASURES Visual acuity, automated visual field testing, pattern electroretinogram, and spectral-domain optical coherence tomography. RESULTS Clinical measures were stable during the follow-up period, and visual acuity was as good as or better than the other visual factors used for monitoring patients. Based on a criterion of 15 or more letters from the Early Treatment Diabetic Retinopathy Study chart, 13 eyes of 8 patients (18%) improved, but 24 months after the onset of symptoms, any further improvements were to no better than 20/100. Acuity recovery occurred in some patients despite continued marked retinal nerve fiber layer thinning indistinguishable from that in patients who did not recover visual acuity. CONCLUSIONS AND RELEVANCE Spontaneous improvement of visual acuity in patients with G11778A LHON is not common and is partial and limited when it occurs, so improvements in vision with adeno-associated virus-mediated gene therapy of a synthetic wild-type ND4 subunit gene should be

    Pneumocystis carinii pneumonia was suggested by a diffuse, bilateral pulmonary uptake of gallium-67 in an asymptomatic, homosexual male with the antibody to the immunodeficiency virus (HIV) who was undergoing staging evaluation for lymphoma clinically localized to a left inguinal lymph node. Chest radiograph and pulmonary function evaluation, including lung volumes, diffusing capacity and arterial blood gases, were within normal limits. Bronchoalveolar lavage revealed Pneumocystis carinii organisms. In this asymptomatic, HIV-positive patient, active alveolar infection, evidenced by abnormal gallium-67 scanning, predated pulmonary physiologic abnormalities. This observation raises questions concerning the natural history of this disease process and the specificity of physiologic tests for excluding disease. It also has implications for the treatment of neoplasia in the HIV-positive patient population.

  11. Developmental pragmatics in normal and abnormal children.

    Bara, B G; Bosco, F M; Bucciarelli, M

    1999-07-01

    We propose a critical review of current theories of developmental pragmatics. The underlying assumption is that such a theory ought to account for both normal and abnormal development. From a clinical point of view, we are concerned with the effects of brain damage on the emergence of pragmatic competence. In particular, the paper deals with direct speech acts, indirect speech acts, irony, and deceit in children with head injury, closed head injury, hydrocephalus, focal brain damage, and autism. Since no single theory covers systematically the emergence of pragmatic capacity in normal children, it is not surprising that we have not found a systematic account of deficits in the communicative performance of brain injured children. In our view, the challenge for a pragmatic theory is the determination of the normal developmental pattern within which different pragmatic phenomena may find a precise role. Such a framework of normal behavior would then permit the systematic study of abnormal pragmatic development.

    Radiographic findings in the sternal abnormalities are often nonspecific, showing appearances from a localized benign lesion to an aggressive lesion as seen with infections and malignant neoplasms. A specific diagnosis of sternal abnormalities can be suggested on the basis of CT and MR characteristics. Familiarity with the presentation and variable appearance of sternal abnormalities may aid the radiologist is suggesting a specific diagnosis. We present among others characteristic radiographic findings of hemangioma, chondrosarcoma, hydatid disease, and SAPHO syndrome. In those cases in which findings are not specific, cross-sectional imaging modalities may help the clinician in their management. (orig.)

    Objectives To study the systemic abnormalities associated with retinal vein occlusion in patients aged ≤50 years with a particular emphasis on atherosclerotic diseases and thrombophilic disorders. Methods Medical charts of patients, aged ≤50 years whose diagnoses were retinal vein occlusions during the period 1995–2015 were retrospectively reviewed. The primary outcome was the number of systemic abnormalities associated with these patients. Secondary outcomes included types of retinal vein occlusion and sites of occlusion. Results Atherosclerotic diseases were the most common systemic abnormalities associated with retinal vein occlusion and accounted for 55.1% of the patients in the study. Hypertension in 27.55%, diabetes mellitus in 16.33%, and 5.1% with dyslipidemia were noted. The number of thrombophilic disorders seemed to be less than expected and were noted in only 5.1%. Other systemic abnormalities included viral hepatitis infection, systemic lupus erythematosus, and acquired immunodeficiency syndrome. Oral contraceptives were used by some patients. Conclusion Atherosclerotic diseases remained the most commonly associated systemic diseases in the majority of these patients. Approach to these patients should include a screening for hypertension, diabetes mellitus, and lipid abnormalities. Thrombophilia should also be considered where no obvious atherosclerotic diseases are found or if the patient is <40 years old, a history of thrombosis or a family history of thrombosis is possible.

    2016-02-01

    In people with a history of low back pain (LBP), structural and functional alterations have been observed at several peripheral and central levels of the sensorimotor pathway. These existing alterations might interact with the way the sensorimotor system responds to pain. We examined this assumption by evaluating the lumbar motor responses to experimental nociceptive input of 15 participants during remission of unilateral recurrent LBP. Quantitative T2 images (muscle functional MRI) were taken bilaterally of multifidus, erector spinae, and psoas at several segmental levels (L3 upper and L4 upper and lower endplate) and during several conditions: 1) at rest, 2) upon trunk-extension exercise without pain, and 3) upon trunk-extension exercise with experimental induced pain at the clinical pain-side (1.5-ml intramuscular hypertonic saline injections in erector spinae). Following experimental pain induction, muscle activity levels similarly reduced for all three muscles, on both painful and nonpainful sides, and at multiple segmental levels (P = 0.038). Pain intensity and localization from experimental LBP were similar as during recalled clinical LBP episodes. In conclusion, unilateral and unisegmental experimental LBP exerts a generalized and widespread decrease in lumbar muscle activity during remission of recurrent LBP. This muscle response is consistent with previous observed patterns in healthy people subjected to the same experimental pain paradigm. It is striking that similar inhibitory patterns in response to pain could be observed, despite the presence of preexisting alterations in the lumbar musculature during remission of recurrent LBP. These results suggest that motor output can modify along the course of recurrent LBP.

    The clinical history and indication (CHI) provided with a radiological examination are critical components of a quality interpretation by the radiologist. A patient's chronic conditions offer the context in which acute symptoms and findings can be interpreted more accurately. Seven pertinent (potentially diagnosis altering) chronic conditions, which are fairly prevalent at our institution, were selected. We analyze if and how in 140 CHIs there was mention of a patient's previously reported chronic condition and if and how the condition was subsequently described in the radiology report using a four-item scheme (Mention/Specialization, Generalization, Common comorbidity, No mention). In 40.7% of CHIs, the condition was rated Mention/Specialization. Therefore, we reject our first hypothesis that the CHI is a reliable source for obtaining pertinent chronic conditions (≥ 90.0%). Non-oncological conditions were significantly more likely rated No mention in the CHI than oncological conditions (58.7 versus 8.3%, P radiology report (χ(2) test, P radiology department to the care chain.

    Full Text Available Abstract Background Short stature is associated with several disorders including wide variations of chromosomal disorders and single gene disorders. The objective of this report is to present the cytogenetic findings in Indonesian patients with short stature. Methods G-banding and interphase/metaphase FISH were performed on short stature patients with and without other clinical features who were referred by clinicians all over Indonesia to our laboratory during the year 2003–2009. Results The results of chromosomal analysis of ninety seven patients (mean age: 10.7 years old were collected. The group of patients with other clinical features showed sex chromosome abnormalities in 45% (18/40 and autosomal abnormalities in 10% (4/40, whereas those with short stature only, 42.1% (24/57 had sex chromosome abnormalities and 1.75% (1/57 had autosomal abnormalities. The autosomal chromosomal abnormalities involved mostly subtelomeric regions. Results discrepancies between karyotype and FISH were found in 10 patients, including detection of low-level monosomy X mosaicism in 6 patients with normal karyotype, and detection of mosaic aneuploidy chromosome 18 in 1 patient with 45,XX,rob(13;14(q10;q10. Statistical analysis showed no significant association between the groups and the type of chromosomal abnormalities. Conclusion Chromosome abnormalities account for about 50% of the short stature patients. Wide variations of both sex and autosomal chromosomes abnormalities were detected in the study. Since three out of five patients had autosomal structural abnormalities involving the subtelomeric regions, thus in the future, subtelomeric FISH or even a more sensitive method such as genomic/SNP microarray is needed to confirm deletions of subtelomeric regions of chromosome 9, 11 and 18. Low-level mosaicism in normal karyotype patients indicates interphase FISH need to be routinely carried out in short stature patients as an adjunct to karyotyping.

    2017-01-01

    Abstract Rationale: It is widely believed that structural abnormalities of the brain contribute to the pathophysiology of schizophrenia. The parietal lobe is a central hub of multisensory integration, and abnormities in this region might account for the clinical features of schizophrenia. However, few cases of parietal encephalomalacia associated with schizophrenia have been described. Patient concerns and Diagnoses: In this paper, we present a case of a 25-year-old schizophrenia patient with abnormal parietal encephalomalacia. The patient had poor nutrition and frequently had upper respiratory infections during childhood and adolescence. She showed severe schizophrenic symptoms such as visual hallucinations for 2 years. After examining all her possible medical conditions, we found that the patient had a lesion consistent with the diagnosis of encephalomalacia in her right parietal lobe and slight brain atrophy. Interventions: The patient was prescribed olanzapine (10 mg per day). Outcomes: Her symptoms significantly improved after antipsychotic treatment and were still well controlled 1 year later. Lessons: This case suggested that parietal encephalomalacia, which might be caused by inflammatory and infectious conditions in early life and be aggravated by undernutrition, might be implicated in the etiology of schizophrenia.

    2002-01-01

    A case of a 9-year-old child with hereditary gingival fibromatosis, supernumerary tooth, chest deformities, auricular cartilage deformation, joint laxity and undescended testes is described. The exact mode of inheritance is unclear; a new mutation pattern is possible. These features resemble but differ from the previously reported Laband syndrome. The dental treatment consisted of surgical removal of the fibrous tissue and conservative restorative treatment under general anesthesia. The dental practitioner should be alert for developmental abnormalities such as supernumerary teeth and delayed tooth eruption. A comprehensive medical history and physical systemic evaluation is essential to rule out other systemic abnormalities. Genetic consultation is mandatory for future family planing.

    With improvements in culturing and banding techniques, amniotic fluid studies now achieve a level of resolution at which the Prader-Willi syndrome (PWS) and Angelman syndrome (AS) region may be questioned. Chromosome 15 heteromorphisms, detected with Q- and R-banding and used in conjunction with PWS/AS region-specific probes, can confirm a chromosome deletion and establish origin to predict the clinical outcome. We report four de novo cases of an abnormal-appearing chromosome 15 in amniotic fluid samples referred for advanced maternal age or a history of a previous chromosomally abnormal child. The chromosomes were characterized using G-, Q-, and R-banding, as well as isotopic and fluorescent in situ hybridization of DNA probes specific for the proximal chromosome 15 long arm. In two cases, one chromosome 15 homolog showed a consistent deletion of the ONCOR PWS/AS region A and B. In the other two cases, one of which involved an inversion with one breakpoint in the PWS/AS region, all of the proximal chromosome 15 long arm DNA probes used in the in situ hybridization were present on both homologs. Clinical follow-up was not available on these samples, as in all cases the parents chose to terminate the pregnancies. These cases demonstrate the ability to prenatally diagnose chromosome 15 abnormalities associated with PWS/AS. In addition, they highlight the need for a better understanding of this region for accurate prenatal diagnosis. 41 refs., 5 figs.

    In a survey of a random sample of the adult population (aged 25-64 yr) from Ghent and Charleroi (n = 1693), 103 (6.1%) showed ECG-abnormalities suggestive of coronary heart disease (Minnesota code I, IV, or V); prevalence was equal in men (6.2%) as in women (6.0%). In men, 30% of ECG-abnormalities suggested an old myocardial infarction as compared to 23.4% in women. Men with abnormal ECG had a positive history of acute myocardial infarction in 23%, as compared to 23.4% in women. Multivariate discriminant function analysis shows that men with abnormal ECG are older, have a higher systolic blood pressure and were more often married. Women with ECG abnormalities were significantly older, had a lower HDL-level and were less educated. So, although the prevalence of ECG abnormalities is almost similar between sexes, they correlate differently with antecedents of infarction and are poorly related to different sets of risk factors in men as compared to women.

    AIM: Biological medicine is hard to fully and scientifically explain the etiological factor and pathogenesis of abnormal behaviors; while, researches on philosophy and psychology (including memetics) are beneficial to better understand and explain etiological factor and pathogenesis of abnormal behaviors. At present, the theory of philosophy and psychology is to investigate the entity of abnormal behavior based on the views of memetics.METHODS: Abnormal behavior was researched in this study based on three aspects, including instinctive behavior disorder, poorly social-adapted behavior disorder and mental or body disease associated behavior disorder. Most main viewpoints of memetics were derived from "The Meme Machine", which was written by Susan Blackmore. When questions about abnormal behaviors induced by mental and psychological diseases and conduct disorder of teenagers were discussed, some researching achievements which were summarized by authors previously were added in this study, such as aggressive behaviors, pathologically aggressive behaviors, etc.RESULTS: The abnormal behaviors mainly referred to a part of people's substandard behaviors which were not according with the realistic social environment, culture background and the pathologic behaviors resulted from people's various psychological diseases. According to the theory of "meme", it demonstrated that the relevant behavioral obstacles of various psychological diseases, for example, the unusual behavior of schizophrenia, were caused, because the old meme was destroyed thoroughly but the new meme was unable to establish; psychoneurosis and personality disorder were resulted in hard establishment of meme; the behavioral obstacles which were ill-adapted to society, for example, various additional and homosexual behaviors, were because of the selfish replications and imitations of "additional meme" and "homosexual meme"; various instinct behavioral and congenital intelligent obstacles were not significance

    Objective: To explore the affecting factors of abnormal fertilization in human IVF/ICSI. Methods: The 15 364 oocytes from 1 004 IVF cycles and 250 ICSI cycles were retrospectively analyzed by the fertilization mode, the age of women, reproductive history, the number of retrieved oocytes of the incidence of normal fertilization rate (2 pronuclear, 2PN) and abnormal fertilization rate (1PN, 3PN, 4PN). Results: 1) The incidence of 1PN rate was lower in the ICSI group than that in the IVF group, however, the incidence of 3PN/4PN fertilization rate was higher in the ICSI group than that in the IVF group. 2) In the ICSI group the incidence of 3PN/4PN was significantly increased when the age of female was older than 35 (P<0.05). 3) The incidence of 1PN in the group of primary infertility was obviously more than that in the group of secondary infertility. 4) Total normal fertility rate in the group of 6-10 retrieved oocytes was higher than that in the other groups(P<0.05), and the incidence rate of abnormal fertilization (1PN, 3PN, 4PN) in the group of 11-15 oocytes was singnificantly higher than that in the other groups (P<0.05). Conclusion: The affecting factors and fertilization mechanism are different between IVF and ICSI: considering multiple factors for every couple of infertility and optimal fertilization modality in IVF may decline the incidence of abnormal fertilization and improve the normal fertilizaton rate.%目的:探讨人卵子体外受精后单原核(PN)和多原核胚胎形成的影响因素,为提高正常受精率探寻可行的方法.方法:回顾性分析1 004个IVF周期和250个ICSI周期,共计15 364个卵细胞资料,研究胚胎原核形成与体外受精方式、女方年龄、生育史、获卵数的关系.结果:①ICSI周期的1PN率明显高于IVF周期,而3PN和4PN形成率则明显低于IVF(P<0.05).②当女方年龄>35岁时,1PN、3PN和4PN形成率均显著高于年龄≤35岁者(P<0.05);当女方年龄在28~35岁时2PN(-正-

    A 62 year old male (R.H.) presented with a mild anemia (Hb 11-12 gm%) and a history of multiple hemorrhagic episodes. The marrow had 40-50% sideroblasts. Marrow chromosomes were normal. His wife was hematologically normal, while one daughter, age 30 years, had a sideroblastic anemia (Hb 11-12 gm%) with 40-50% sideroblasts in the marrow. Her anemia was first noted at age 15 years. Administration of vitamin B6 did not correct the anemia in either the father or daughter. Platelet abnormalities inherited jointly with this disorder are described for the first time. Both R.H. and his daughter had prolonged bleeding times, with normal PTT, PT times, fVIII:C, fVIII:Ag levels, and vWF multimers, which may rule out a von Willebrand's disease. They have normal platelet numbers but abnormally low platelet adhesiveness and greatly depressed ADP, collagen, and epinephrine responsiveness. Response to ristocetin was in the low normal range, and aggregation with thrombin was normal. While desmopressin completely normalized R.H.'s bleeding time, none of these platelet parameters were improved. No differences in the SDS PAGE protein patterns of RH platelets could be detected in comparison to normal samples. His platelets took up and released serotonin (5HT) normally, and electron micrographs defined no morphological abnormalities. However, no ATP was released from platelets activated with collagen, and when followed by thrombin about fourfold greater ATP was released by control platelets as compared to RH platelets. The dense granule fraction derived from RH platelets contained about 20% the level of ATP, 40% the level of ADP, and 50% the level of 5HT detected in a normal sample. The results indicate that the bleeding disorder is related to a non-classical heritable storage pool defect. The connection between the inherited sideroblastic anemia and platelet defects is obscure.

    2012-01-01

    The natural history of Barrett's esophagus (BE) is difficult to quantify because,by definition,it should describe the course of the condition if left untreated.Pragmatically,we assume that patients with BE will receive symptomatic treatment with acid suppression,usually a proton pump inhibitor,to treat their heartburn.This paper describes the development of complications of stricture,ulcer,dysplasia and adenocarcinoma from this standpoint.Controversies over the definition of BE and its implications in clinical practice are presented.The presence of intestinal metaplasia and its relevance to cancer risk is discussed,and the need to measure the extent of the Barrett's epithelium (long and short segments) using the Prague guidelines is emphasized.Guidelines and international consensus over the diagnosis and management of BE are being regularly updated.The need for expert consensus is important due to the lack of randomized trials in this area.After searching the literature,we have tried to collate the important studies regarding progression of Barrett's to dysplasia and adenocarcinoma.No therapeutic studies yet reported show a clear reduction in the development of cancer in BE.The effect of pharmacological and surgical intervention on the natural history of Barrett's is a subject of ongoing research,including the Barrett's Oesophagus Surveillance Study and the aspirin and esomeprazole cancer chemoprevention trial with interesting results.The geographical variation and the wide range of outcomes highlight the difficulty of providing an individualized risk profile to patients with BE.Future studies on the interaction of genome wide abnormalities in Barrett's and their interaction with environmental factors may allow individualization of the risk of cancer developing in BE.

    Full Text Available Background: Abnormal uterine bleeding (AUB is one of the most common clinical problemsin gynecology. Transvaginal sonography (TVS and hysteroscopy are two diagnostic methods forpatients with AUB. For most of the patients with AUB, diagnostic hysteroscopy can be done inclinic with minimal discomfort and much lower expense than operative room.Materials and Methods: In our clinical trial study, from March 21, 2005 to March 20, 2007,patients with AUB in Ahwaz Imam Khomayni hospital, after history and physical examinationsunderwent TVS. Of those, 147 patients with normal TVS entered the study and were considered foroutpatient hysteroscopy. Patients with endometrial cavity lesion were scheduled for operation room,and those with empty endometrial cavity aspiration biopsy were done outpatiently. Specimens weresent to pathologist for examination.Results: All the patients were divided into three groups: group 1 or minority was under 30 yearsold (7 women, group 2 was 30-40 years, and group 3 or majority was over 40 years old (96women. 115 patients (78.2% had normal and 32 patients (21.8% had abnormal hysteroscopicresults. 116 patients (78.8% had normal and 31 patients (21.2% had abnormal pathologic results;moreover, cervical canal polyp was the most common lesion hysteroscopically and pathologicallyin all groups.Conclusion: Of 147 patients (100% with AUB and normal TVS, 32 patients (21.8% wereabnormal hysteroscopically. Cervical canal polyps may be missed by transvaginal sonography, butcan be diagnosed by hysteroscopy. In patients with AUB and normal TVS, hysteroscopy can beused as the second step.

    Fifty patients with unexplained vertigo (36) or lightheadedness (14) are evaluated, all of whom had abnormal ENGs and normal audiograms. Five hour insulin glucose tolerance tests were performance on all patients, with insulin levels being obtained fasting and at one-half, one, two, and three hours. The results of this investigation were remarkable. Borderline or abnormal insulin levels were discovered in 82% of patients; 90% were found to have either an abnormal glucose tolerance test or at least borderline insulin levels. The response to treatment in these dizzy patients was also startling, with appropriate low carbohydrate diets improving the patient's symptoms in 90% of cases. It is, therefore, apparent that the earliest identification of carbohydrate imbalance with an insulin glucose tolerance test is extremely important in the work-up of the dizzy patients.

    2016-01-01

    The effect of physiological and pathological abnormal excitation of a myocyte on the spiral waves is investigated based on the cellular automaton model. When the excitability of the medium is high enough, the physiological abnormal excitation causes the spiral wave to meander irregularly and slowly. When the excitability of the medium is low enough, the physiological abnormal excitation leads to a new stable spiral wave. On the other hand, the pathological abnormal excitation destroys the spiral wave and results in the spatiotemporal chaos, which agrees with the clinical conclusion that the early after depolarization is the pro-arrhythmic mechanism of some anti-arrhythmic drugs. The mechanisms underlying these phenomena are analyzed. Project supported by the National Natural Science Foundation of China (Grant Nos. 11365003 and 11165004).

    An efficient and automated abnormality detection method can significantly reduce the burden of screening of the enormous visual information resulting from capsule endoscopic procedure. As a pre-processing stage, color enhancement could be useful to improve the image quality and the detection performance. Therefore, in this paper, we have proposed a two-stage automated abnormality detection algorithm. In the first stage, an adaptive color enhancement method based on Retinex theory is applied on the endoscopic images. In the second stage, an efficient salient region detection algorithm is applied to detect the clinically significant regions. The proposed algorithm is applied on a dataset containing images with diverse pathologies. The algorithm can successfully detect a significant percentage of the abnormal regions. From our experiment, it was evident that color enhancement method improves the performance of abnormality detection. The proposed algorithm can achieve a sensitivity of 97.33% and specificity of 79%, higher than state-of-the-art performance.

    2016-12-01

    We introduce quantum history states and their mathematical framework, thereby reinterpreting and extending the consistent histories approach to quantum theory. Through thought experiments, we demonstrate that our formalism allows us to analyze a quantum version of history in which we reconstruct the past by observations. In particular, we can pass from measurements to inferences about ‘what happened’ in a way that is sensible and free of paradox. Our framework allows for a richer understanding of the temporal structure of quantum theory, and we construct history states that embody peculiar, non-classical correlations in time.

    1975-04-01

    This study was undertaken to determine the teratogenic potential of methylmercury on chick embryogenesis. Methylmercuric chloride was dissolved in sodium bicarbonate (0.2%) and administered to the chick embryos at doses ranging from 0.0009 to 0.010 mg per egg. The injections were made at days 2 and 3 on incubation (Groups A and B). All the embryos including controls were examined on the 7th day of incubation. Methylmercury poisoning was observed to be both embryolethal and teratogenic. Within the two groups, embryolethality was higher in Group A. The following congenital abnormalities were observed: exencephaly, shortened and twisted limbs, microphthalmia, shortened and twisted neck, beak abnormalities, everted viscera, reduced body size and hemorrhage all over the body. Exencephaly and limb abnormalities were very common. No differences in the incidence and types of gross abnormalities within both the groups (A and B) were noted. The incidence of malformations among the controls was low. The results of present investigation show that methylmercury poisoning is both embryolethal and teratogenic to early chick embryogenesis.

    This article outlines the ability of MR imaging in the detection and presurgical evaluation of congenital abnormalities of the thoracic aorta (CATA). Congenital abnormalities of the thoracic aorta may be found incidentally on chest radiographs in patients without symptoms, or it can be associated with clinical findings which are very variable depending on the association with congenital cardiac malformations or vascular ring. When CATA is suspected as the cause of anomalies in the mediastinum in asymptomatic patients, confirmation of the abnormality should be by MR imaging allowing precise evaluation of the thoracic aorta and origin of the principal arteries. When CATA is considered because clinical findings indicate coarctation of the aorta, vascular ring or associated cardiac disorder, evaluation with ultrasound can be complemented by MR, which in most cases will replace the diagnostic catheterization.

    Full Text Available Abstract Background Childhood obesity is on the rise and is a major risk factor for type 2 diabetes later in life. Recent evidence indicates that abnormalities that increase risk for diabetes may be initiated early in infancy. Since the offspring of women with diabetes have an increased long-term risk for obesity and type 2 diabetes, the impact of maternal metabolic abnormalities on early nutrition and infant metabolic trajectories is of considerable interest. Human breast milk, the preferred food during infancy, contains not only nutrients but also an array of bioactive substances including metabolic hormones. Nonetheless, only a few studies have reported concentrations of metabolic hormones in human milk specifically from women with metabolic abnormalities. We aim to investigate the impact of maternal metabolic abnormalities in pregnancy on human milk hormones and subsequently on infant development over the first year of life. The objective of this report is to present the methodology and design of this study. Methods/Design The current investigation is a prospective study conducted within ongoing cohort studies of women and their offspring. Pregnant women attending outpatient obstetrics clinics in Toronto, Canada were recruited. Between April 2009 and July 2010, a total of 216 pregnant women underwent a baseline oral glucose tolerance test and provided medical and lifestyle history. Follow-up visits and telephone interviews are conducted and expected to be completed in October 2011. Upon delivery, infant birth anthropometry measurements and human breast milk samples are collected. At 3 and 12 months postpartum, mothers and infants are invited for follow-up assessments. Interim telephone interviews are conducted during the first year of offspring life to characterize infant feeding and supplementation behaviors. Discussion An improved understanding of the link between maternal metabolic abnormalities in pregnancy and early infant nutrition may

    There are good motivations for considering some type of quantum histories formalism. Several possible formalisms are known, defined by different definitions of event and by different selection criteria for sets of histories. These formalisms have a natural interpretation, according to which nature somehow chooses one set of histories from among those allowed, and then randomly chooses to realise one history from that set; other interpretations are possible, but their scientific implications are essentially the same. The selection criteria proposed to date are reasonably natural, and certainly raise new questions. For example, the validity of ordering inferences which we normally take for granted --- such as that a particle in one region is necessarily in a larger region containing it --- depends on whether or not our history respects the criterion of ordered consistency, or merely consistency. However, the known selection criteria, including consistency and medium decoherence, are very weak. It is not possibl...

    Objective To observe the clinical features of myeloid and lymphoid neoplasms with t (4; 22) induced abnormalities of the platelet-derived growth factor receptor alpha (PDGFRA) to increase the identification and reduce the misdiagnosis. Methods The clinical data of one patient with myeloid and lymphoid neoplasm with t (4; 22) induced abnormalities of PDGFRA diagnosed in June 2010 was retrospectively analyzed. We summarized the clinical features, morphology, genetics, diagnostic criteria and therapy about this kind of disease. Results The patient had a clinical manifestation and bone marrow smear result of chronic myelogenous leukemia (CML). But the result of genetic analysis found no translocation of chromosomes 9 and 22 juxtaposing BCR and ABL gens. Cytogenetic analysis showed an abnormal karyotype with rearrangement of chromosomes 4 and 22. So the patient was diagnosed myeloid and lymphoid neoplasms with t (4; 22) induced abnormalities of PDGFRA. After receiving interferon and hydroxyurea,the patient achieved complete hematologic remission. Conclusion Myeloid and lymphoid neoplasms with t (4; 22) induced abnormalities of PDGFRA is a rare kind of disease. Its clinical feature is similar to that of CML.

  18. Central Mechanisms of Abnormal Sympathoexcitation in Chronic Heart Failure

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available It has been recognized that the sympathetic nervous system is abnormally activated in chronic heart failure, and leads to further worsening chronic heart failure. In the treatment of chronic heart failure many clinical studies have already suggested that the inhibition of the abnormal sympathetic hyperactivity by beta blockers is beneficial. It has been classically considered that abnormal sympathetic hyperactivity in chronic heart failure is caused by the enhancement of excitatory inputs including changes in peripheral baroreceptor and chemoreceptor reflexes and chemical mediators that control sympathetic outflow. Recently, the abnormalities in the central regulation of sympathetic nerve activity mediated by brain renin angiotensin system-oxidative stress axis and/or proinflammatory cytokines have been focused. Central renin angiotensin system, proinflammatory cytokines, and the interaction between them have been determined as the target of the sympathoinhibitory treatment in experimental animal models with chronic heart failure. In conclusion, we must recognize that chronic heart failure is a syndrome with an abnormal sympathoexcitation, which is caused by the abnormalities in the central regulation of sympathetic nerve activity.

    Background Cardiac defects can be the presenting symptom in patients with mutations in the X-linked gene FLNA. Dysfunction of this gene is associated with cardiac abnormalities, especially in the left ventricular outflow tract, but can also cause a congenital malformation of the cerebral cortex. We noticed that some patients diagnosed at the neurogenetics clinic had first presented to a cardiologist, suggesting that earlier recognition may be possible if the diagnosis is suspected. Methods and results From the Erasmus MC cerebral malformations database 24 patients were identified with cerebral bilateral periventricular nodular heterotopia (PNH) without other cerebral cortical malformations. In six of these patients, a pathogenic mutation in FLNA was present. In five a cardiac defect was also found in the outflow tract. Four had presented to a cardiologist before the cerebral abnormalities were diagnosed. Conclusions The cardiological phenotype typically consists of aortic or mitral regurgitation, coarctation of the aorta or other left-sided cardiac malformations. Most patients in this category will not have a FLNA mutation, but the presence of neurological complaints, hyperlaxity of the skin or joints and/or a family history with similar cardiac or neurological problems in a possibly X-linked pattern may alert the clinician to the possibility of a FLNA mutation.

    Objective. To illustrate the variety of paravertebral muscle abnormalities as seen on computed tomography (CT) or magnetic resonance imaging (MRI) in association with spinal osteoblastomas and correlate the findings with the presence of scoliosis. Design. In a retrospective study the clinical notes, plain radiographic, CT and/or MRI features were reviewed for the presence of scoliosis and paravertebral muscle abnormality (either inflammation or atrophy). Patients. Twelve patients (7 male, 5 female) with a mean age of 17 years were studied. Three lesions occurred in the cervical spine, five in the thoracic spine and four in the lumbar spine. Results and conclusions. Nine patients had scoliosis. All patients with a thoracic or lumbar lesion and scoliosis (n=8) had an associated abnormality of the paravertebral muscles (usually atrophy with fatty replacement). One patient with a lumbar lesion and no scoliosis had normal paravertebral muscles. One patient with a cervical lesion had thoracic scoliosis but no muscle abnormality in the cervical region, while two patients with cervical lesions and no scoliosis showed muscle abnormalities. The results support the clinical hypothesis that scoliosis in patients with spinal osteoblastoma is due to paravertebral muscle spasm, although this would not appear to be the case for cervical lesions.

    Many nail abnormalities have traditionally been described in association with rheumatoid arthritis (RA), but their specificity has never been assessed in a controlled study. Our purpose was to evaluate the frequency and the specificity of nail changes associated with RA in a case-controlled study including 50 patients suffering from RA and 50 controls. For each patient, a general skin examination was performed and the 20 nails were examined. The nail features were noted and classified. A chi 2 test or a Fisher test was used to compare the two groups. The only nail abnormalities significantly associated with RA were longitudinal ridging on nine or 10 finger nails (29 patients in the RA group vs. three in the controls, chi 2: P nail (24 patients vs. 10, chi 2: P nail changes were noticed but were not frequent enough to be significant. The presence of longitudinal ridging on the finger nails was significantly associated with RA.

    2014-01-01

    Full Text Available Magnetic resonance imaging (MRI techniques have been used to quantitatively assess focal and network abnormalities. Idiopathic generalized epilepsy (IGE is characterized by bilateral synchronous spike–wave discharges on electroencephalography (EEG but normal clinical MRI. Dysfunctions involving the neocortex, particularly the prefrontal cortex, and thalamus likely contribute to seizure activity. To identify possible morphometric and functional differences in the brains of IGE patients and normal controls, we employed measures of thalamic volumes, cortical thickness, gray–white blurring, fractional anisotropy (FA measures from diffusion tensor imaging (DTI and fractional amplitude of low frequency fluctuations (fALFF in thalamic subregions from resting state functional MRI. Data from 27 patients with IGE and 27 age- and sex-matched controls showed similar thalamic volumes, cortical thickness and gray–white contrast. There were no differences in FA values on DTI in tracts connecting the thalamus and prefrontal cortex. Functional analysis revealed decreased fALFF in the prefrontal cortex (PFC subregion of the thalamus in patients with IGE. We provide minimum detectable effect sizes for each measure used in the study. Our analysis indicates that fMRI-based methods are more sensitive than quantitative structural techniques for characterizing brain abnormalities in IGE.

    2015-12-01

    Full Text Available One of the consistent findings among various studies on HIV has been simultaneous multiorgan dysfunction. Cardiovascular disorders are now most common cause of mortality worldwide. With more effective and widespread treatment of HIV in resource-rich settings, morbidity and mortality from non-AIDS-related events have surpassed those from AIDS-related events with cardiovascular diseases emerging as an important cause of death in HIV-infected patients relative to the decreasing incidence of opportunistic disease. Various studies have reported a 1.5-fold increase in the rate of cardiovascular events in HIV-infected individuals compared to control populations. MATERIAL AND METHODS The aim of the study was to the find the prevalence and types of different cardiovascular abnormalities in HIV positive patients and assess their association with CD4 counts. Consecutive 82 patients, HIV positive patients fulfilling the inclusion criteria and giving informed consent were included in the study. All patients were subjected to history taking and a detailed physical examination. Blood counts, renal function tests, lipid profile and CD4 counts were estimated and patients were subjected to 12-lead ECG, chest X-ray and 2D/Colour Doppler Echocardiogram. RESULTS Of the 82 patients studied 47.46% had evidence of cardiovascular involvement, out of which 12% had clinical features of heart failure while electrocardiographic changes were seen in 35% of patients in the form of sinus tachycardia (27%, QTc prolongation (10% and left sided chamber enlargements (6%. Echocardiographic abnormalities were noted in 39 patients (47.56% including fractional shortening associated with systolic dysfunction (26.8%. The mean CD4 count in patients with echocardiographic abnormalities was found to be 58.87±29.80, whereas in patients without echocardiographic abnormalities it was 136.53±38.80 (p<0.0001.

    1993-11-01

    The authors retrospectively studied seven patients who had in situ fusion as adolescents for high-grade (IV, V) spondylolisthesis unresponsive to more conservative means. All patients achieved solid bony union; their pain was relieved; and hamstring spasm had resolved. The authors sought to determine whether crouch gait or any other abnormalities could be demonstrated in patients exhibiting clinical parameters of success. Each patient underwent gait analysis, radiographic analysis, and a physical examination. Four of seven patients demonstrated slight degrees of forward trunk lean during varying phases of gait accompanied by increased hip flexion. One patient demonstrated increased trunk extension accompanied by limited hip flexion. Two patients were essentially normal. The authors were unable to quantify residual crouch in these patients with solidly fused high-grade spondylolisthesis.

    Patients with sickle cell disease exhibits numerous kidney structural and functional abnormalities, changes that are seen along the entire length of the nephron. Changes are most marked in patients with homozygous sickle cell anemia, but are also seen in those with compound heterozygous states and the sickle cell trait. The renal features of sickle cell disease include some of the most common reasons for referral to nephrologists, such as hematuria, proteinuria, tubular disturbances and chronic kidney disease. Therapy of these conditions requires specialized knowledge of their distinct pathogenic mechanisms.

    Full Text Available Kabuki syndrome is a rare congenital anomaly, characterized by five fundamental features, the "Pentad of Niikawa": dysmorphic facies, skeletal anomalies, dermatoglyphic abnormalities, mild to moderate mental retardation and postnatal growth deficiency. Patients present characteristic external ocular features, nonetheless they may also present significant ocular abnormalities. We report a case of a brazilian child diagnosed with Kabuki syndrome, addressing the clinical features observed, with emphasis on the ocular manifestations. This case highlights the existence of this syndrome and all of its complexity. The identification of preventable causes of loss of vision underlines the value of detailed ophthalmologic examination of Kabuki syndrome patients.

    We present the first case of abnormal neuroimaging in a case of infant botulism. The clinical findings of the patient with constipation, bulbar weakness, and descending, symmetric motor weakness are consistent with the classic findings of infant botulism. Magnetic resonance imaging (MRI), however, revealed restricted diffusion in the brain and enhancement of the cervical nerve roots. Traditionally, normal neuroimaging was used to help differentiate infant botulism from other causes of weakness in infants. Abnormal neuroimaging is seen in other causes of weakness in an infant including metabolic disorders and hypoxic-ischemic injury, but these diagnoses did not fit the clinical findings in this case. The explanation for the MRI abnormalities in the brain and cervical nerve roots is unclear as botulinum toxin acts at presynaptic nerve terminals and does not cross the blood-brain barrier. Possible explanations for the findings include inflammation from the botulinum toxin at the synapse, alterations in sensory signaling and retrograde transport of the botulinum toxin. The patient was treated with human botulism immune globulin and had rapid recovery in weakness. A stool sample from the patient was positive for Type A Clostridium botulinum toxin eventually confirming the diagnosis of infant botulism. The findings in this case support use of human botulism immune globulin when the clinical findings are consistent with infant botulism despite the presence of MRI abnormalities in the brain and cervical nerve roots.

    Full Text Available Abstract Background We have investigated whether replacing conventional karyotyping by SNP array analysis in cases of foetal ultrasound abnormalities would increase the diagnostic yield and speed of prenatal diagnosis in clinical practice. Findings/results From May 2009 till June 2011 we performed HumanCytoSNP-12 array (HCS (http://www.Illumina.com analysis in 207 cases of foetal structural abnormalities. HCS allows detecting unbalanced genomic abnormalities with a resolution of about 150/200 kb. All cases were selected by a clinical geneticist after excluding the most common aneuploidies by RAD (rapid aneuploidy detection. Pre-test genetic counselling was offered in all cases. In 24/207 (11,6% foetuses a clinically relevant genetic abnormality was detected. Only 8/24 abnormalities would have been detected if only routine karyotyping was performed. Submicroscopic abnormalities were found in 16/207 (7,7% cases. The array results were achieved within 1-2 weeks after amniocentesis. Conclusions Prenatal SNP array testing is faster than karyotyping and allows detecting much smaller aberrations (~0.15 Mb in addition to the microscopic unbalanced chromosome abnormalities detectable with karyotyping (~ > 5 Mb. Since karyotyping would have missed 66% (16/24 of genomic abnormalities in our cohort, we propose to perform genomic high resolution array testing assisted by pre-test counselling as a primary prenatal diagnostic test in cases of foetal ultrasound abnormalities.

    This study evaluated the acceptance of using computers to take a medical history by rural Arkansas patients. Sex, age, race, education, previous computer experience and owning a computer were used as variables. Patients were asked a series of questions to rate their comfort level with using a computer to take their medical history. Comfort ratings ranged from 30 to 45, with a mean of 36.8 (SEM = 0.67). Neither sex, race, age, education, owning a personal computer, nor prior computer experience had a significant effect on the comfort rating. This study helps alleviate one of the concerns--patient acceptance--about the increasing use of computers in practicing medicine.

    A few authors have described the clinical picture of dysthymia in groups of elderly patients and pointed out differences from literature reports of dysthymia in younger adults. The present study, an attempt to analyze age effects on clinical characteristics of dysthymia throughout a lifetime, was performed in a sample of 106 patients, all aged > or =18 years, who were diagnosed according to DSM-IV. The patients were evaluated using: (1) a semistructured interview to assess clinical features, family history and previous treatments; (2) the Hamilton Depression Rating Scale; (3) the Interview for Recent Life Events; and (4) the Structured Clinical Interview for DSM-IV Disorders. Statistical analysis with stepwise logistic regression revealed that age was positively related to concomitant medical illnesses and to the total score of recent life events, but negatively related to the presence of avoidant or dependent personality disorders. The data suggested different etiologic pathways in older and younger patients. Dysthymia appeared to be associated in younger adults with abnormalities of personality; in the elderly, with a history of health problems and life losses.

    Full Text Available Objective. To develop and evaluate process indicators relevant to biopsychosocial history taking in patients with chronic back and neck pain. Methods. The SCEBS method, covering the Somatic, Psychological (Cognition, Emotion, and Behavior, and Social dimensions of chronic pain, was used to evaluate biopsychosocial history taking by manual physical therapists (MPTs. In Phase I, process indicators were developed while in Phase II indicators were tested in practice. Results. Literature-based recommendations were transformed into 51 process indicators. Twenty MTPs contributed 108 patient audio recordings. History taking was excellent (98.3% for the Somatic dimension, very inadequate for Cognition (43.1% and Behavior (38.3%, weak (27.8% for Emotion, and low (18.2% for the Social dimension. MTPs estimated their coverage of the Somatic dimension as excellent (100%, as adequate for Cognition, Emotion, and Behavior (60.1%, and as very inadequate for the Social dimension (39.8%. Conclusion. MTPs perform screening for musculoskeletal pain mainly through the use of somatic dimension of (chronic pain. Psychological and social dimensions of chronic pain were inadequately covered by MPTs. Furthermore, a substantial discrepancy between actual and self-estimated use of biopsychosocial history taking was noted. We strongly recommend full implementation of the SCEBS method in educational programs in manual physical therapy.

    The present paper deals with the problematic nature of the phenomenological grasping of the consciousness of the body and its pathological modifications. The reasoning is oriented by the doctrine of Husserl of the so-called sentiments as the fundamentals of the experience of the own body. This basic approach does not only seem to be basically for a psychology of the consciousness of the body, but also to give the theoretical-conceptual structure for a great number of psychopathological modifications. Subsequent to a criticism of the conventional use of the term 'hallucination of the body' we attempt to chart elements of a scheme of the abnormal consciousness of the body.

    Myeloid leukemia is a clinically and genetically heterogeneous disease. Cytogenetic studies have revealed specific chromosomal abnormalities, such as translocations, and inversions. Fusion proteins derived from these abnormalities were identified in various subtypes of leukemia. Because most of these fusion proteins were not sufficient to induce leukemia by themselves in mouse models, additional oncogenic events have been thought to be necessary for leukemogenesis. Recently, a hypothesis called "two-hit model" for leukemia has been proposed. Two broad classes of mutations that proliferative or survival advantage of hematopoietic progenitors and impaired differentiation are required for inducing leukemia. In this article, we summarize some typical chromosomal abnormalities or gene mutations associated with myeloid leukemia on the basis of this hypothesis.

    The clinical use of stem cells in cell-based therapeutics for degenerative diseases requires development of criteria for defining normal stem cells to ensure safe transplantation. Currently, identification of abnormal from normal stem cells is based on extensive ex vivo and in vivo testing. Raman...... microscopy is a label-free method for rapid and sensitive detection of changes in cells' bio-molecular composition. Here, we report that by using Raman spectroscopy, we were able to map the distribution of different biomolecules within 2 types of stem cells: adult human bone marrow-derived stromal stem cells...... and human embryonic stem cells and to identify reproducible differences in Raman's spectral characteristics that distinguished genetically abnormal and transformed stem cells from their normal counterparts.

    Objective To investigate relationship between abnormal gestational glucose metabolism and pregnancy outcome of the woman. Methods 1 636 pregnant women who received antenatal examination in Shannxi Provincial Maternal and Child Health Hospital in a period from January to June, 2008 were screened at their 24~28 weeks of gestation with 50g glucose challenge test (GCT). Those pregnant women with abnormal GCT results further received oral 75g glucose tolerance test (OGTT). According to OGTT results, the pregnant women were divided into 2 groups: GDM group (n=69) and gestational impaired glucose tolerance group (GIGT group, n=124). 300 pregnant women with normal glucose metabolism were as controls. All of them were followed up untill delivery and the perinatal outcomes in the 3groups were compared. Results The incidence of GDM was 4.21% and that of GIGT was 7.58%. The incidences of hypertensive disorder complicating pregnancy, polyhydramnios, premature rupture of membrane and premature delivery in GDM group were higher than those in the control group (χ2=4.660,11.530,5.193,4.661 respectively,all P<0.05).In GIGT group ,the incidences of polyhydramnios and premature rupture of membrane were significantly higher than those in the control group(χ2=12.450,6.325,respectively,both P<0.05). Conclusion The pregnant women with GDM or GIGT have significantly high incidences of obstetric complications and rate of cesarean section. So, screening of GDM should be strengthened and early diagnosis, early treatment, gestational supervision and guidance should be carried out in order to reduce incidence rates of maternal and infantile complications.%目的 探讨妊娠期糖代谢异常与妊娠结局的关系.方法 选取2008年1~6月在陕西省妇幼保健院进行产前检查的1 636名孕妇,于24~28周进行50g葡萄糖筛查试验,异常者行75g糖耐量试验,按糖代谢异常情况分为妊娠期糖尿病组(69例)和妊娠期糖耐量受损组(124例);

    2014-10-01

    Full Text Available Objectives: The aim of this study was to establish the relationship between background amplitude and interictal abnormalities in routine electroencephalography (EEG. Methods: This retrospective audit was conducted between July 2006 and December 2009 at the Department of Clinical Physiology at Sultan Qaboos University Hospital (SQUH in Muscat, Oman. A total of 1,718 electroencephalograms (EEGs were reviewed. All EEGs were from patients who had been referred due to epilepsy, syncope or headaches. EEGs were divided into four groups based on their amplitude: group one ≤20 μV; group two 21–35 μV; group three 36–50 μV, and group four >50 μV. Interictal abnormalities were defined as epileptiform discharges with or without associated slow waves. Abnormalities were identified during periods of resting, hyperventilation and photic stimulation in each group. Results: The mean age ± standard deviation of the patients was 27 ± 12.5 years. Of the 1,718 EEGs, 542 (31.5% were abnormal. Interictal abnormalities increased with amplitude in all four categories and demonstrated a significant association (P <0.05. A total of 56 EEGs (3.3% had amplitudes that were ≤20 μV and none of these showed interictal epileptiform abnormalities. Conclusion: EEG amplitude is an important factor in determining the presence of interictal epileptiform abnormalities in routine EEGs. This should be taken into account when investigating patients for epilepsy. A strong argument is made for considering long-term EEG monitoring in order to identify unexplained seizures which may be secondary to epilepsy. It is recommended that all tertiary institutions provide EEG telemetry services.

  20. Abnormal visuomotor processing in schizophrenia

    2016-01-01

    Full Text Available Subtle disturbances of visual and motor function are known features of schizophrenia and can greatly impact quality of life; however, few studies investigate these abnormalities using simple visuomotor stimuli. In healthy people, electrophysiological data show that beta band oscillations in sensorimotor cortex decrease during movement execution (event-related beta desynchronisation (ERBD, then increase above baseline for a short time after the movement (post-movement beta rebound (PMBR; whilst in visual cortex, gamma oscillations are increased throughout stimulus presentation. In this study, we used a self-paced visuomotor paradigm and magnetoencephalography (MEG to contrast these responses in patients with schizophrenia and control volunteers. We found significant reductions in the peak-to-peak change in amplitude from ERBD to PMBR in schizophrenia compared with controls. This effect was strongest in patients who made fewer movements, whereas beta was not modulated by movement in controls. There was no significant difference in the amplitude of visual gamma between patients and controls. These data demonstrate that clear abnormalities in basic sensorimotor processing in schizophrenia can be observed using a very simple MEG paradigm.

This is the first DTI study to directly compare WM tract coherence with tractography and fractional anisotropy (FA) across the schizophrenia spectrum in a large sample of demographically matched HCs (n = 55), medication-naive SPD patients (n = 49), and unmedicated/never-medicated schizophrenia patients (n = 22) to determine whether (a) frontal-striatal-temporal WM tract abnormalities in schizophrenia are similar to, or distinct from those observed in SPD; and (b) WM tract abnormalities are associated with clinical symptom severity indicating a common underlying pathology across the spectrum. Compared with both the HC and SPD groups, schizophrenia patients showed WM abnormalities, as indexed by lower FA in the temporal lobe (inferior longitudinal fasciculus) and cingulum regions. SPD patients showed lower FA in the corpus callosum genu compared with the HC group, but this regional abnormality was more widespread in schizophrenia patients. Across the schizophrenia spectrum, greater WM disruptions were associated with greater symptom severity. Overall, frontal-striatal-temporal WM dysconnectivity is attenuated in SPD compared with schizophrenia patients and may mitigate the emergence of psychosis.

    Full Text Available Abstract Background Pregnancies complicated by abnormal umbilical artery Doppler blood flow patterns often result in the baby being born both preterm and growth-restricted. These babies are at high risk of milk intolerance and necrotising enterocolitis, as well as post-natal growth failure, and there is no clinical consensus about how best to feed them. Policies of both early milk feeding and late milk feeding are widely used. This randomised controlled trial aims to determine whether a policy of early initiation of milk feeds is beneficial compared with late initiation. Optimising neonatal feeding for this group of babies may have long-term health implications and if either of these policies is shown to be beneficial it can be immediately adopted into clinical practice. Methods and Design Babies with gestational age below 35 weeks, and with birth weight below 10th centile for gestational age, will be randomly allocated to an "early" or "late" enteral feeding regimen, commencing milk feeds on day 2 and day 6 after birth, respectively. Feeds will be gradually increased over 9-13 days (depending on gestational age using a schedule derived from those used in hospitals in the Eastern and South Western Regions of England, based on surveys of feeding practice. Primary outcome measures are time to establish full enteral feeding and necrotising enterocolitis; secondary outcomes include sepsis and growth. The target sample size is 400 babies. This sample size is large enough to detect a clinically meaningful difference of 3 days in time to establish full enteral feeds between the two feeding policies, with 90% power and a 5% 2-sided significance level. Initial recruitment period was 24 months, subsequently extended to 38 months. Discussion There is limited evidence from randomised controlled trials on which to base decisions regarding feeding policy in high risk preterm infants. This multicentre trial will help to guide clinical practice and may also

    Objective To explore the effect of nursing interventions on the changes of S/D ratio of umbilical artery blood flow with different sleeping postures and pregnancy outcomes. Methods A total of 99 pregnant women with a gestational duration of 28 to 42 weeks, who had abnormal S/D ratios in umbilical artery blood flow were randomly divided into intervention group and control group. The intervention group was asked to take different sleeping postures based the different S/D ratios including horizontal posture, left - lateral posture and right - lateral posture while the control group was not told in terms of sleeping postures. Results 39.6% pregnant women (19/48) in the intervention group had S/D ratios return to the normal range after proper instructions in sleeping postures, which was higher than the 17.6% (9/51) in the control group. The difference was statistically significant (P<0.05). The rates of cesarean section, fetal growth restriction, premature delivery, fetal distress, asphxia neonatorum, oligohysramnios, cloudy amniotic fluid in the intervention group were reduced (F<0.05). Conclusion To take proper sleeping postures may improve umbilical artery blood flow, bring S/D ratio back to the normal range, lower rates of cesarean section, reduce pregnancy complications and improve the perinatal infants prognosis.%目的 探讨护理干预下不同睡眠体位脐动脉血流S/D比值的变化及对妊娠结局的影响.方法 将99例妊娠28-42周经多普勒超声检测脐动脉血流S/D比值异常增高的孕妇随机分为干预组和对照组,干预组根据在平卧位、左侧卧位及右侧卧位3个不同体位时的S/D比值,对孕妇睡眠体位进行指导,而对照组未特意嘱咐睡眠体位.结果 干预组经指导采取正确睡眠体位后,有39.6%(19/48)的孕妇异常S/D比值降至孕周正常值,明显高于对照组的17.6%(9/51),差异有统计学意义(P<0.05);剖宫产、胎儿宫内生长受限、早产

    2012-02-03

    BACKGROUND: The EEG is a commonly requested test on patients attending psychiatric services, predominantly to investigate for a possible organic brain syndrome causing behavioural changes. AIMS: To assess referrals for EEG from psychiatric services in comparison with those from other sources. We determine which clinical factors were associated with an abnormal EEG in patients referred from psychiatric sources. METHODS: A retrospective review of EEG requests in a 1-year period was performed. Analysis of referral reasons for psychiatric patients was undertaken, and outcome of patients referred from psychiatric services post-EEG was reviewed. RESULTS: One thousand four hundred and seventy EEGs were reviewed, of which 91 (6.2%) were referred from psychiatry. Neurology service referrals had detection rates of abnormal EEGs of 27%, with psychiatric referrals having the lowest abnormality detection rate of 17.6% (p < 0.1). In psychiatric-referred patients the only significant predictors found of an abnormal EEG were a known history of epilepsy (p < 0.001), being on clozapine (p < 0.05), and a possible convulsive seizure (RR = 6.51). Follow-up data of 53 patients did not reveal a significant clinical impact of EEG results on patient management. CONCLUSIONS: Many patients are referred for EEG from psychiatric sources despite a relatively low index of suspicion of an organic brain disorders, based on reasons for referral documented, with an unsurprising low clinical yield.

    Full Text Available Aberrant sensory processing plays a fundamental role in the pathophysiology of dystonia; however, its underpinning neural mechanisms in relation to dystonia phenotype and genotype remain unclear. We examined temporal and spatial discrimination thresholds in patients with isolated laryngeal form of dystonia (LD, who exhibited different clinical phenotypes (adductor vs. abductor forms and potentially different genotypes (sporadic vs. familial forms. We correlated our behavioral findings with the brain gray matter volume and functional activity during resting and symptomatic speech production. We found that temporal but not spatial discrimination was significantly altered across all forms of LD, with higher frequency of abnormalities seen in familial than sporadic patients. Common neural correlates of abnormal temporal discrimination across all forms were found with structural and functional changes in the middle frontal and primary somatosensory cortices. In addition, patients with familial LD had greater cerebellar involvement in processing of altered temporal discrimination, whereas sporadic LD patients had greater recruitment of the putamen and sensorimotor cortex. Based on the clinical phenotype, adductor form-specific correlations between abnormal discrimination and brain changes were found in the frontal cortex, whereas abductor form-specific correlations were observed in the cerebellum and putamen. Our behavioral and neuroimaging findings outline the relationship of abnormal sensory discrimination with the phenotype and genotype of isolated LD, suggesting the presence of potentially divergent pathophysiological pathways underlying different manifestations of this disorder.

    Background: There were 1.2 million registered heroin users in China by the end of 2011, but little research in the country has focused on the neuropsychological functioning of these individuals.Aim: Assess error-related negativity (ERN) - an important indicator of high-level cognitive functioning - among males with heroin dependence undergoing rehabilitation.Method: Twenty male patients in a rehabilitation center who met DSM-IV criteria for heroin dependence and 15 healthy male controls completed 800 trials of Erikson flanker tasks to provoke ERN waves on the 32-electrode electroencephalograph (EEG) when erroneous responses are induced by presenting incongruent flankers around the target stimulus. Mean error rates and reaction times for the task, and the amplitude and latency of crude ERN waves and standardized ERN waves (created by subtracting the wave for correct responses from that for incorrect responses) at three frontal midline EEG electrodes (Fz, FCz, and Cz) were compared between patients and controls.Results: There was no significant difference in error rates between patients and controls but the reaction times for both erroneous and correct responses were shorter in patients than controls. The amplitude of both crude and standardized ERN waves was lower in patients than controls, but this difference became non-significant after adjustment for the lower educational level in the patient group. The latency of the peak value in both the crude and standardized ERN waves was significantly shorter in the patient group; this difference remained significant after adjustment for educational level. There was a significant correlation between the negative amplitude of the standardized ERN wave and the duration of heroin use.Conclusion: These findings suggest impaired impulse control and abnormal error-monitoring functions in persons with a history of heroin dependence and add to the growing literature on the neurological mechanisms related to cognitive dysfunction in

    Movement abnormalities are frequently reported in children with 22q11.2 deletion syndrome (22q11.2DS), but knowledge in this area is scarce in the increasing adult population. We report on five individuals illustrative of movement disorders and other motor abnormalities in adults with 22q11.2DS. In addition to an increased susceptibility to neuropsychiatric disorders, seizures, and early-onset Parkinson disease, the underlying brain dysfunction associated with 22q11.2DS may give rise to an increased vulnerability to multiple movement abnormalities, including those influenced by medications. Movement abnormalities may also be secondary to treatable endocrine diseases and congenital musculoskeletal abnormalities. We propose that movement abnormalities may be common in adults with 22q11.2DS and discuss the implications and challenges important to clinical practice.

    Full Text Available We test the hypothesis that strategies which are long on portfolios of looser stocks and short on portfolios of winner stocks generate abnormal returns in Brazil. This type of evidence for the US stock market was interpreted by The Bondt and Thaler (1985 as reflecting systematic evaluation mistakes caused by investors overreaction to news related to the firm performance. We found evidence of contrarian strategies profitability for horizons from 3 months to 3 years in a sample of stock returns from BOVESPA and SOMA from 1986 to 2000. The strategies are more profitable for shorter horizons. Therefore, there was no trace of the momentum effect found by Jagadeesh and Titman (1993 for the same horizons with US data. There are remaing unexplained positive returns for contrarian strategies after accounting for risk, size, and liquidity. We also found that the strategy profitability is reduced after the Real Plan, which suggests that the Brazilian stock market became more efficient after inflation stabilization.

    Regression-smoothed maternal age-specific rates of six different categories of cytogenetic abnormalities in recent large-scale prenatal cytogenetic studies were multiplied by independently derived fetal selection coefficients--factors that adjust for the excess likelihood of spontaneous loss of cytogenetically abnormal fetuses--to obtain estimated maternal age-specific rates of these categories of cytogenetic abnormalities in live-born infants. The derived rates apply to women whose only risk factor is advanced maternal age. The categories analyzed were 47,+21 (Down's syndrome), 47,+18 (Edwards' syndrome), 47,+13 (Patau's syndrome), 47,XXY (Klinefelter's syndrome), 47,XXX, and the group of other clinically significant abnormalities considered collectively. The rate of all clinically significant abnormalities considered together derived in this study was about five per 1,000 at age 35 years, 15 per 1,000 at age 40 years, and 50 per 1,000 at age 45 years.

    Full Text Available Abstract Background Because of low copy repeats (LCRs and common inversion polymorphisms, the human chromosome 8p is prone to a number of recurrent rearrangements. Each of these rearrangements is associated with several phenotypic features. We report on a patient with various clinical malformations and developmental delay in connection with an inverted duplication event, involving chromosome 8p. Methods Chromosome analysis, multicolor banding analysis (MCB, extensive fluorescence in situ hybridization (FISH analysis and microsatellite analysis were performed. Results The karyotype was characterized in detail by multicolor banding (MCB, subtelomeric and centromere-near probes as 46,XY,dup(8(pter->p23.3::p12->p23.3::p23.3->qter. Additionally, microsatellite analysis revealed the paternal origin of the duplication and gave hints for a mitotic recombination involving about 6 MB in 8p23.3. Conclusion A comprehensive analysis of the derivative chromosome 8 suggested a previously unreported mechanism of formation, which included an early mitotic aberration leading to maternal isodisomy, followed by an inverted duplication of the 8p12p23.3 region.

  8. Abnormalities of the Exocrine Pancreas in Type 1 Diabetes

    Rodriguez-Calvo, Teresa; Battaglia, Manuela

    2016-01-01

    Type 1 diabetes (T1D) is considered a pancreatic beta cell-specific disease that results in absolute insulin deficiency. Nevertheless, clinical studies from 1940 onwards showed that patients with T1D had an abnormal exocrine pancreas due to the presence of subclinical exocrine insufficiency and acinar atrophy. Exocrine abnormalities are an important, and mostly neglected, characteristic associated with T1D. It is however still unclear whether the exocrine dysfunction in T1D is a primary damage caused by the same pathogenic event that led to beta cell destruction or secondary to beta cell loss. In this review, we collect evidence supporting the hypothesis that T1D is a combined endocrine-exocrine disease in which the loss of functional beta cell mass is most clinically apparent.

    Objective To compare clinical variables in patients with rapid-cycling bipolar I or II disorder and a recent history of substance use disorder (SUD). Method Cross-sectional data from 2 studies of patients with rapid-cycling bipolar I disorder or rapid-cycling bipolar II disorder and a recent history of SUD were used to retrospectively assess the differences in clinical variables between the subtypes. The studies were conducted from November 1997 to February 2007 at University Hospitals Case Medical Center, Case Western Reserve University School of Medicine, Cleveland, Ohio. Extensive clinical interview and the Mini-International Neuropsychiatric Interview were used to ascertain DSM-IV diagnoses of rapid-cycling bipolar disorder, SUDs, and other Axis I disorders and to collect clinical variables. The Addiction Severity Index (ASI), Global Assessment Scale (GAS), and the Medical Outcomes Study 36-ltem Short-Form Health Survey were used to measure the severity of impairment at the initial assessment. One-way analysis of variance or χ2 was used for significance tests. A Bonferroni adjustment was applied for multiple comparisons. Results Of 245 patients with rapid-cycling bipolar disorder (rapid-cycling bipolar I disorder, N = 191; rapid-cycling bipolar II disorder, N = 54) and a recent history of SUD, the demographics were similar. A significantly higher rate of panic disorder was observed in patients with rapid-cycling bipolar I disorder than in those with rapid-cycling bipolar II disorder (odds ratio = 3.72, 95% CI = 1.66 to 8.32, p = .008). A significantly higher psychiatric composite score on the ASI was also found in patients with rapid-cycling bipolar I disorder than in those with rapid-cycling bipolar II disorder even after Bonferroni adjustment (p = .0007). There were no significant differences between the subtypes in the rates of previous hospitalization or suicide attempt, early childhood verbal, physical, or sexual abuse, lifetime substance abuse or

    Abnormalities in cortical structure are commonly observed in children with dyslexia in key regions of the "reading network." Whether alteration in cortical features reflects pathology inherent to dyslexia or environmental influence (e.g., impoverished reading experience) remains unclear. To address this question, we compared MRI-derived metrics of cortical thickness (CT), surface area (SA), gray matter volume (GMV), and their lateralization across three different groups of children with a historical diagnosis of dyslexia, who varied in current reading level. We compared three dyslexia subgroups with: (1) persistent reading and spelling impairment; (2) remediated reading impairment (normal reading scores), and (3) remediated reading and spelling impairments (normal reading and spelling scores); and a control group of (4) typically developing children. All groups were matched for age, gender, handedness, and IQ. We hypothesized that the dyslexia group would show cortical abnormalities in regions of the reading network relative to controls, irrespective of remediation status. Such a finding would support that cortical abnormalities are inherent to dyslexia and are not a consequence of abnormal reading experience. Results revealed increased CT of the left fusiform gyrus in the dyslexia group relative to controls. Similarly, the dyslexia group showed CT increase of the right superior temporal gyrus, extending into the planum temporale, which resulted in a rightward CT asymmetry on lateralization indices. There were no group differences in SA, GMV, or their lateralization. These findings held true regardless of remediation status. Each reading level group showed the same "double hit" of atypically increased left fusiform CT and rightward superior temporal CT asymmetry. Thus, findings provide evidence that a developmental history of dyslexia is associated with CT abnormalities, independent of remediation status.

    Background Male-factor infertility is a common condition, and etiology is unknown for a high proportion of cases. Abnormal epigenetic programming of the germline is proposed as a possible mechanism compromising spermatogenesis of some men currently diagnosed with idiopathic infertility. During germ cell maturation and gametogenesis, cells of the germ line undergo extensive epigenetic reprogramming. This process involves widespread erasure of somatic-like patterns of DNA methylation followed by establishment of sex-specific patterns by de novo DNA methylation. Incomplete reprogramming of the male germ line could, in theory, result in both altered sperm DNA methylation and compromised spermatogenesis. Methodology/Principal Finding We determined concentration, motility and morphology of sperm in semen samples collected by male members of couples attending an infertility clinic. Using MethyLight and Illumina assays we measured methylation of DNA isolated from purified sperm from the same samples. Methylation at numerous sequences was elevated in DNA from poor quality sperm. Conclusions This is the first report of a broad epigenetic defect associated with abnormal semen parameters. Our results suggest that the underlying mechanism for these epigenetic changes may be improper erasure of DNA methylation during epigenetic reprogramming of the male germ line. PMID:18074014

    The acupuncture has been practiced in China for more than 3000 years and was spread to Europe and American from the sixteenth to the nineteenth century. The history of acupuncture research was initiated in the eighteenth century and developed rapidly since then. In the past, physicians tried hard to apply acupuncture into clinical practice, while scientists were focused on the possible characteristics of acupoints and meridians. In the modern time, scientists have strived hard to evaluate the real effectiveness of acupuncture and the underlying physiological and biological mechanisms of acupuncture. Reviewing research history from past to present, we are delighted to witness this wonderful development. Accumulated evidences that acupuncture is beneficial in various conditions significantly enhanced our understanding the mechanisms of acupuncture treatment. However, there is still no conclusive evidence in acupuncture clinical studies. The clinical research still needs great improving, while the basic research results need to be appropriately transformed into clinical outcomes. Based on current achievements, we believe that although the challenges and difficulties exist, a more collaborative, innovative, and integrated approach will help us to achieve further progress in future acupuncture research.

    In December 2012 a manuscript entitled "Tællelyset" ['The Tallow Candle'] was discovered in an archive. The story was subsequently presented to the world as Hans Christian Andersen's first fairy tale and rather bombastically celebrated as such. In this book it is demonstrated that the text cannot...... from a point-by-point tracing of 'the origins and history' of Hans Christian Andersen's famous fairy tales. Where did the come from? How did they become the iconic texts that we know today? On this background it becomes quite clear that "Tællelyset" is a modern pastiche and not a genuine Hans Christian......

    Pearson marrow-pancreas syndrome is a multisystem mitochondrial disorder characterized by bone marrow failure and pancreatic insufficiency. Children who survive the severe bone marrow dysfunction in childhood develop Kearns-Sayre syndrome later in life. Here we report on four new cases with this condition and define their biochemical abnormalities. Three out of four patients presented with failure to thrive, with most of them having normal development and head size. All patients had evidence of bone marrow involvement that spontaneously improved in three out of four patients. Unique findings in our patients were acute pancreatitis (one out of four), renal Fanconi syndrome (present in all patients, but symptomatic only in one), and an unusual organic aciduria with 3-hydroxyisobutyric aciduria in one patient. Biochemical analysis indicated low levels of plasma citrulline and arginine, despite low-normal ammonia levels. Regression analysis indicated a significant correlation between each intermediate of the urea cycle and the next, except between ornithine and citrulline. This suggested that the reaction catalyzed by ornithine transcarbamylase (that converts ornithine to citrulline) might not be very efficient in patients with Pearson syndrome. In view of low-normal ammonia levels, we hypothesize that ammonia and carbamylphosphate could be diverted from the urea cycle to the synthesis of nucleotides in patients with Pearson syndrome and possibly other mitochondrial disorders.

    The clotting process is a dynamic array of multiple processes which can be described in four phases: platelet plug initiation and formation, clotting process propagation by the coagulation cascade, clotting termination by antithrombotic mechanisms and clot removal by fibrinolysis. The liver plays a central role in each of these phases of clotting process, as it synthesizes the majority of coagulation factors and proteins involved in fibrinolysis as well as thrombopoeitin, which is responsible for platelet production from megakaryocytes. Many pathological processes associated with cirrhosis, such as portal hypertension and endothelial dysfunction, as well as co-morbid conditions, may also alter the coagulation process. Consequently, patients with liver disease have a disturbed balance of procoagulant and anti-coagulant factors which deviates from the normal coagulation cascade. This situation poses an additional problem in the diagnostic and therapeutic approach to this group of patients, since traditional coagulation test may not be reliable for assessing bleeding or thrombotic risk and traditional transfusional strategies may not be applicable in cirrhotic patients. In this article, we review the pathophysiological bases of coagulation abnormalities, in cirrhotic patients, the diagnostic therapeutic strategies to be followed and its impact on the clinical outcome in the cirrhotic patient.

    2012-12-01

    Full Text Available Patients with psychosis display structural brain abnormalities in multiple brain regions. The disorder is characterized by a putative prodromal period called ultra-high-risk (UHR status, which precedes the onset of full-blown psychotic symptoms. Recent studies on psychosis have focused on this period. Neuroimaging studies of UHR individuals for psychosis have revealed that the structural brain changes observed during the established phases of the disorder are already evident prior to the onset of the illness. Moreover, certain brain regions show extremely dynamic changes during the transition to psychosis. These neurobiological features may be used as prognostic and predictive biomarkers for psychosis. With advances in neuroimaging techniques, neuroimaging studies focusing on gray matter abnormalities provide new insights into the pathophysiology of psychosis, as well as new treatment strategies. Some of these novel approaches involve antioxidants administration, because it is suggested that this treatment may delay the progression of UHR to a full-blown psychosis and prevent progressive structural changes. The present review includes an update on the most recent developments in early intervention strategies for psychosis and potential therapeutic treatments for schizophrenia. First, we provide the basic knowledge of the brain regions associated with structural abnormalities in individuals at UHR. Next, we discuss the feasibility on the use of magnetic resonance imaging (MRI-biomarkers in clinical practice. Then, we describe potential etiopathological mechanisms underlying structural brain abnormalities in prodromal psychosis. Finally, we discuss the potentials and limitations related to neuroimaging studies in individuals at UHR.

    Introduction This study describes cerebral ultrasound abnormalities caused by late-onset sepsis (LOS) in very preterm infants with a gestational age of < 32 weeks and/or birthweight < 1500 grams. Methods The prospective study (“INFANT study”) included 117 preterm infants with suspected LOS. Proven LOS was defined as a positive blood culture after 72 hours of life. In case of coagulase-negative staphylococci an elevated C-reactive protein was additionally required to establish proven LOS. Patients were identified as proven LOS and patients with only clinical symptoms of LOS. Cerebral ultrasound images were obtained in the first week after birth, during/after LOS and before discharge. Cerebral findings were divided in no/minor and major abnormalities. Results Eighty-six preterm infants had proven LOS and 31 preterm infants had only clinical signs of LOS. Four infants were excluded because pre-existing major brain abnormalities. No significant differences (p = 0.624) for incidence of major brain abnormalities on cerebral ultrasound were found. Conclusion No differences were revealed in prevalence of major brain abnormalities between the groups with proven LOS and with clinical signs of LOS. Both infants with a gram negative sepsis developed major brain abnormalities, whereas only two of 66 preterm infants coagulase-negative staphylococci sepsis developed major brain abnormalities.

    Hair dysplasias are congenital or acquired alterations which often involve the hair shaft. Hair shaft abnormalities are characterized by changes in color, density, length and structure. Hair shaft alterations often result from structural changes within the hair fibers and cuticles which may lead to brittle and uncombable hair. The hair of patients with hair shaft diseases feels dry and looks lusterless. Hair shaft diseases may occur as localized or generalized disorders. Genetic predisposition or exogenous factors produce and maintain hair shaft abnormalities. Hair shaft diseases are separated into those with and those without increased hair fragility. In general, optic microscopy and polarized light microscopy of hair shafts provide important clues to the diagnosis of isolated hair shaft abnormalities or complex syndromes. To establish an exact diagnosis of dysplastic hair shafts, a structured history and physical examination of the whole patient are needed which emphasizes other skin appendages such as the nails, sweat and sebaceous glands. Profound knowledge on hair biology and embryology is necessary to understand the different symptom complexes. Therapy of hair shaft disorders should focus on the cause. In addition, minimizing traumatic influences to hair shafts, such as drying hair with an electric dryer or permanent waves and dyes, is important. A short hairstyle is more suitable for patients with hair shaft disorders.

    Full Text Available Purpose: Surgeons performing an ilioinguinal exposure for acetabular fracture surgery need to be aware of aberrant findings such as inguinal hernias and spermatic cord lesions. The purpose of this study is to report these occurrences in a clinical series of adult males undergoing acetabular fracture fixation and a series of adult male cadavers. The secondary aim is to characterize these abnormalities to aid surgeons in detecting these abnormalities preoperatively and coordinating a surgical plan with a general surgeon.Methods: Clinical study- Retrospective review of treated acetabular fractures through an ilioinguinal approach. Incidence of inguinal canal and spermatic cord abnormalities requiring general surgery consultation were identified. Corresponding CT scans were reviewed and radiographic characteristics of the spermatic cord abnormalities and/or hernias were noted.Cadaveric study- 18 male cadavers dissected bilaterally using an ilioinguinal exposure. The inguinal canal and the contents of the spermatic cord were identified and characterized.Results: Clinical Study- 5.7% (5/87 of patients had spermatic cord lesion and/or inguinal hernia requiring general surgical intervention. Preoperative pelvic CT scan review identified abnormalities noted intraoperatively in four of the five patients. Cord lipomas visualized as enlargements of the spermatic cord with homogeneous density. Hernias visualized as enlarged spermatic cords with heterogeneous density. Cadaver Study- 31% (11/36 of cadavers studied had spermatic cord and/or inguinal canal abnormalities. Average cord diameter in those with abnormalities was 24.9 mm (15-28 compared to 16 mm (11-22 in normal cords, which was statistically significant.Conclusion: The clinical and cadaveric findings emphasize the importance of understanding inguinal abnormalities and the value of detecting them preoperatively. The preoperative pelvic CT scans were highly sensitive in detecting inguinal abnormalities.

    Full Text Available Aim of the Study: The aim of this study was to evaluate platelet enzyme activity in cases of leukemia. Materials and Methods: Platelet enzymes glucose-6-phosphate dehydrogenase (G6PD, pyruvate kinase (PK and hexokinase (HK were studied in 47 patients of acute and chronic leukemia patients, 16 patients with acute myeloid leukemia (AML(13 relapse, three in remission, 12 patients with acute lymphocytic leukemia (ALL (five in relapse, seven in remission, 19 patients with chronic myeloid leukemia (CML. Results: The platelet G6PD activity was significantly low in cases of AML, ALL and also in CML. G6PD activity was normalized during AML remission. G6PD activity, although persistently low during ALL remission, increased significantly to near-normal during remission (P < 0.05 as compared with relapse (P < 0.01. Platelet PK activity was high during AML relapse (P < 0.05, which was normalized during remission. Platelet HK however was found to be decreased during all remission (P < 0.05. There was a significant positive correlation between G6PD and PK in cases of AML (P < 0.001 but not in ALL and CML. G6PD activity did not correlate with HK activity in any of the leukemic groups. A significant positive correlation was however seen between PK and HK activity in cases of ALL remission (P < 0.01 and CML (P < 0.05. Conclusions: Both red cell and platelet enzymes were studied in 36 leukemic patients and there was no statistically significant correlation between red cell and platelet enzymes. Platelet enzyme defect in leukemias suggests the inherent abnormality in megakaryopoiesis and would explain the functional platelet defects in leukemias.

    Full Text Available ABSTRACT: Piriformis Syndrome is a cause for Low back pain whi ch is most of the times misdiagnosed as it may mimic with various other con ditions. Abnormal condition of the Piriformis muscle such as hypertrophy, inflammation, or anatomic variations may lead to this condition. Reported incidence rates for Piriformis S yndrome among patients with low back pain vary widely, from 5% to 36%. Etiology of Piriformis Syndrome is also variable. It can be primary due to anatomical problems or secondary due to vario us other causes like trauma, local ischemia, limb-length discrepancy etc. Diagnosis of Piriformis Syndrome is complex. History with various clinical tests along with MRI, EMG (El ectromyography and Diagnostic blocks may help to diagnose this condition. Here is a review of Piriformis syndrome for better understanding of the problem so that the diagnosis a nd management are appropriate. KEY WORDS:Piriformis Syndrome.

    A 46-year-old Chinese woman with a history of cholecystectomy and appendicectomy presented to the emergency department with symptoms of intestinal obstruction. Physical examination revealed central abdominal tenderness but no clinical features of peritonism. Plain radiography of the abdomen revealed a grossly distended large bowel loop with the long axis extending from the right lower abdomen toward the epigastrium, and an intraluminal air-fluid level. These findings were suspicious for an acute caecal volvulus, which was confirmed on subsequent contrast-enhanced computed tomography (CT) of the abdomen and pelvis. CT demonstrated an abnormal positional relationship between the superior mesenteric vein and artery, indicative of an underlying intestinal malrotation. This case highlights the utility of preoperative imaging in establishing the diagnosis of an uncommon cause of bowel obstruction. It also shows the importance of recognising the characteristic imaging features early, so as to ensure appropriate and expedient management, thus reducing patient morbidity arising from complications.

    2011-07-01

    Full Text Available Abstract Background To combat the pandemic of human immunodeficiency virus 1 (HIV-1, a successful vaccine will need to cope with the variability of transmissible viruses. Human hosts infected with HIV-1 potentially harbour many viral variants but very little is known about viruses that are likely to be transmitted, or even if there are viral characteristics that predict enhanced transmission in vivo. We show for the first time that genetic divergence consistent with a single transmission event in vivo can represent several years of pre-transmission evolution. Results We describe a highly unusual case consistent with a single donor transmitting highly related but distinct HIV-1 variants to two individuals on the same evening. We confirm that the clustering of viral genetic sequences, present within each recipient, is consistent with the history of a single donor across the viral env, gag and pol genes by maximum likelihood and Bayesian Markov Chain Monte Carlo based phylogenetic analyses. Based on an uncorrelated, lognormal relaxed clock of env gene evolution calibrated with other datasets, the time since the most recent common ancestor is estimated as 2.86 years prior to transmission (95% confidence interval 1.28 to 4.54 years. Conclusion Our results show that an effective design for a preventative vaccine will need to anticipate extensive HIV-1 diversity within an individual donor as well as diversity at the population level.

    An investigation was conducted of malfunctions of snubbers (seismic-shock arrestors) in service in nuclear power plants. The construction and use of snubbers is summarized, and the history of snubber problems in nuclear service is reviewed. Reports of many hundreds of snubber malfunctions were found in the abnormal-occurrence reports of the docket literature. The great majority of these abnormal occurrences consisted of hydraulic snubbers whose hydraulic fluid had leaked out because of deteriorated seals; snubbers that were damaged in manufacture, shipping, installation, refitting, or use; and snubbers whose performance did not match service requirements. Additional information about the failures was obtained from the reactor operators, snubber manufacturers, reactor vendors, and independent laboratories. The abnormal occurrences were classified into 12 categories. Analyses of the causes of the individual abnormalities are presented, and preliminary comments on the current state of snubber manufacture and use are made.

    We examined the impact of Massachusetts insurance reform on the care of women at six community health centers with abnormal breast and cervical cancer screening to investigate whether stability of insurance coverage was associated with more timely diagnostic resolution. We conducted Cox proportional hazards models to predict time from cancer screening to diagnostic resolution, examining the impact of 1) insurance status at time of screening abnormality, 2) number of insurance switches over a three-year period, and 3) insurance history over a three-year period. We identified 1,165 women with breast and 781 with cervical cancer screening abnormalities. In the breast cohort, Medicaid insurance at baseline, continuous public insurance, and losing insurance predicted delayed resolution. We did not find these effects in the cervical cohort. These data provide evidence that stability of health insurance coverage with insurance reform nationally may improve timely care after abnormal cancer screening in historically underserved women.

    AIM: To evaluate the prevalence of abnormalities of the uterine cervix in women with inflammatory bowel disease (IBD) when compared to healthy controls.METHODS: One hundred and sixteen patients with IBD [64 with Crohn's disease (CD) and 52 with ulcerative colitis (UC)] were matched to 116 healthy controls by age (+/- 2 years) at the time of most recent papanicolaou (Pap) smear. Data collected consisted of age, race, marital status, number of pregnancies,abortions/miscarriages, duration and severity of IBD,Pap smear results within five years of enrollment, and treatment with immunosuppressive drugs. Pap smear results were categorized as normal or abnormal including atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LGSIL), and high-grade squamous intraepithelial lesion (HGSIL). RESULTS: The median age at the time of Pap smear was 46 (range: 17-74) years for the IBD group and matched controls (range: 19-72 years). There were more Caucasian subjects than other ethnicities in the IBD patient group (P = 0.025), as well as fewer abortions (P = 0.008), but there was no significant difference regarding marital status. Eighteen percent of IBD patients had abnormal Pap smears compared to 5% of controls (P = 0.004). Subgroup analysis of the IBD patients revealed no significant differences between CD and UC patients in age, ethnicity, marital status, number of abortions, disease severity, family history of IBD, or disease duration. No significant difference was observed in the number of abnormal Pap smears or the use of immunosuppressive medications between CD and UC patients (P = 0.793). No definitive observation could be made regarding HPV status, as this was not routinely investigated during the timeframe of our study.CONCLUSION: Diagnosis of IBD in women is related to an increased risk of abnormal Pap smear, while type of IBD and exposure to immunosuppressive medications are not. This has significant implications for

    Full Text Available Abstract Background Hematological abnormalities are a common complication of HIV infection. These abnormalities increase as the disease advances. Bone marrow abnormalities occur in all stages of HIV infection. Methods Two hundred HIV infected individual were screened for hematological abnormalities from March 2007–March 2008. Absolute CD4 cell count analysis was carried out by flowcytometry. Depending on the results of the primary screening further investigations were performed, like iron studies, hemolytic work up, PNH work up and bone marrow evaluation. Other investigations included coagulation profile, urine analysis, blood culture (bacterial, fungal, mycobacterial, serology for Epstein Barr virus (EBV, Cytomegalovirus (CMV, Hepatitis B and C, and Parvo B19 infection. Results The most common hematological abnormality was anemia, seen in 65.5% (131/200 patients. Iron deficiency anemia was seen in 49.2% (/200 cases while anemia of chronic disease occurred in 50.7% (/200 cases. Bone marrow evaluation was carried out in 14 patients out of which staging marrow was performed in 2 cases of non-Hodgkin's lymphoma (NHL and did not show any bone marrow infiltration. In remaining12 cases bone marrow was done for evaluation of pancytopenia. Among patients with pancytopenia 50% (6/12 showed granulomas (4 were positive for AFB, 2 were positive for fungal cryptococci, 25% (3/12 showed hemophagocytosis. There was a strong negative correlation between anemia and CD4 counts in this study. Thrombocytopenia was seen in 7% (14/200 cases and had no significant correlation with CD4 counts. No patient had absolute neutrophil count (ANC Conclusion Anemia in HIV patients can be a good clinical indicator to predict and access the underlying immune status. Patients should be investigated for hematological manifestations and appropriate steps should be taken to identify and treat the reversible factors.

    2012-01-01

    Objective: The FEBSTAT study is a prospective study that seeks to determine the acute and long-term consequences of febrile status epilepticus (FSE) in childhood. Methods: From 2003 to 2010, 199 children age 1 month to 5 years presenting with FSE (>30 minutes) were enrolled in FEBSTAT within 72 hours of the FSE episode. Of these, 191 had imaging with emphasis on the hippocampus. All MRIs were reviewed by 2 neuroradiologists blinded to clinical details. A group of 96 children with first simple FS who were imaged using a similar protocol served as controls. Results: A total of 22 (11.5%) children had definitely abnormal (n = 17) or equivocal (n = 5) increased T2 signal in the hippocampus following FSE compared with none in the control group (p < 0.0001). Developmental abnormalities of the hippocampus were more common in the FSE group (n = 20, 10.5%) than in controls (n = 2, 2.1%) (p = 0.0097) with hippocampal malrotation being the most common (15 cases and 2 controls). Extrahippocampal imaging abnormalities were present in 15.7% of the FSE group and 15.6% of the controls. However, extrahippocampal imaging abnormalities of the temporal lobe were more common in the FSE group (7.9%) than in controls (1.0%) (p = 0.015). Conclusions: This prospective study demonstrates that children with FSE are at risk for acute hippocampal injury and that a substantial number also have abnormalities in hippocampal development. Follow-up studies are in progress to determine the long-term outcomes in these children. PMID:22843278

    2016-05-01

    Tinnitus is a common symptom that usually originates in the middle ear. Vascular causes of pulsatile tinnitus are categorized by the location of the source of the noise within the cerebral-cervical vasculature: arterial, arteriovenous, and venous. Arterial stenosis secondary to atherosclerotic disease or dissection, arterial anatomic variants at the skull base, and vascular skull base tumors are some of the more common causes of arterial and arteriovenous pulsatile tinnitus. Noninvasive imaging is indicated to evaluate for possible causes of pulsatile tinnitus, and should be followed by catheter angiography if there is a strong clinical suspicion for a dural arteriovenous fistula.

    Ossification of the Achilles tendon is a rare clinical entity that is characterized by the presence of an ossific mass contained within the fibrocartilaginous substance of the tendon. Because the radiographic features of this condition have not been documented entirely and the magnetic resonance (MR) imaging findings have not been determined, a review of 16 affected tendons in 12 patients was performed in an attempt to characterize the imaging abnormalities associated with this process. MR imaging was performed in three Achilles tendons which demonstrated thickening of the tendons at the level of the ossifications and a lack of intratendinous signal abnormalities compatible with acute tendinitis. Signal intensity similar to that of bone marrow was present in the ossifications. (orig.)

    2016-05-01

    Approximately 30% of women will experience abnormal uterine bleeding (AUB) during their life time. Previous terms defining AUB have been confusing and imprecisely applied. As a consequence, both clinical management and research on this common problem have been negatively impacted. In 2011, the International Federation of Gynecology and Obstetrics (FIGO) Menstrual Disorders Group (FMDG) published PALM-COEIN, a new classification system for abnormal bleeding in the reproductive years. Terms such as menorrhagia, menometrorrhagia, metrorrhagia, dysfunctional uterine bleeding, polymenorrhea, oligomenorrhea, and uterine hemorrhage are no longer recommended. The PALM-COEIN system was developed to standardize nomenclature to describe the etiology and severity of AUB. A brief description of the PALM-COEIN nomenclature is presented as well as treatment options for each etiology. Clinicians will frequently encounter women with AUB and should report findings utilizing the PALM-COEIN system.
