Sexuality in teenagers with epilepsy

Objectives: In adults with epilepsy it is well known that the epileptic syndrome, seizure frequency and antiepileptic drug use may influence sexual function and behavior. However, knowledge acquired with adult populations has been extrapolated to teenagers, based on the supposition that these patients are influenced by similar factors. This study aimed to evaluate aspects related to sexuality obtained from female adolescents with epilepsy. Methods: We carried out a prospective study of 35 female adolescents, with epilepsy, with ages from 10 to 20 years, and epileptic syndromes diagnosed according to ILAE criteria (1989). Information on sexual function and behavior of adolescents with epilepsy was evaluated by use of a standard questionnaire. Exclusion criteria were lack of menarche, previous endocrine or chronic clinical disorders, and moderate to severe mental retardation. Results: No differences were observed between the age at first sexual intercourse, sexual activity, libido and orgasm of adolescents with epilepsy when compared to controls. Epilepsy clinical variables Such as age of onset, duration and severity had no significant relationship with distinct aspects of sexual function and behavior. Conclusion: Adolescents with epilepsy represent a special patient group because, even with their chronic disorder, they have an active sexual life, despite the severity of their disorder. Therefore, aspects related to sexuality require special attention by health professionals when attending to adolescents with epilepsy. (C) 2008 Elsevier Inc. All rights reserved.

Hemorrhagic vesicle-bullous lesions in Henoch-Schonlein purpura and review of literature

Introduction: The characteristic feature of Henoch-Schonlein purpura (HSP) is palpable purpura, however hemorrhagic vesicles and blisters have been rarely reported. Case reports: From January 1983 to December 2007, 5079 patients were followed in our Pediatric Rheumatology Unit, 232 (4.6%) of them with the diagnosis of HSP. Three female patients (1.3%) presented hemorrhagic vesicles and bullous lesions associated with palpable purpura. In one case the lesions were severe and widespread, and in another they preceded the typical purpuric lesions. In both cases, skin biopsy disclosed leukocytoclastic vasculitis with IgA and C3 deposits. Two patients healed with residual lesions: ulcers in one case and skin hyperpigmentation in two of them. Discussion: Hemorrhagic vesicle-bullous lesions are rare in HSP This manifestation may represent a more severe and prolonged disease course with scars or may precede typical skin lesions.

Elevated left and reduced right orbitomedial prefrontal fractional anisotropy in adults with bipolar disorder revealed by tract-based spatial statistics

Context Diffusion tensor imaging (DTI) studies in adults with bipolar disorder (BD) indicate altered white matter (WM) in the orbitomedial prefrontal cortex (OMPFC), potentially underlying abnormal prefrontal corticolimbic connectivity and mood dysregulatioin in BD. Objective: To use tract-based spatial statistics (TBSS) to examine VVM skeleton (ie, the most compact whole-brain WM) in subjects with BD vs healthy control subjects. Design: Cross-sectional, case-control, whole-brain DTI using TBSS. Setting: University research institute. Participants: Fifty-six individuals, 31 having a DSM-IV diagnosis of BD type 1 (mean age, 35.9 years [age range, 24-52 years]) and 25 controls (mean age, 29.5 years [age range, 19-52 years]). Main Outcome Measures: Fractional anisotropy (FA) longitudinal and radial diffusivities in subjects with BD vs controls (covarying for age) and their relationships with clinical and demographic variables. Results: Subjects with BD vs controls had significantly greater FA (t > 3.0, P <=.05 corrected) in the left uncinate fasciculus (reduced radial diffusivity distally and increased longitudinal diffusivity centrally), left optic radiation (increased longitudinal diffusivity), and right anterothalamic radiation (no significant diffusivity change). Subjects with BD vs controls had significantly reduced FA (t > 3.0, P <=.05 corrected) in the right uncinate fasciculus (greater radial diffusivity). Among subjects with BD, significant negative correlations (P <.01) were found between age and FA in bilateral uncinate fasciculi and in the right anterothalamic radiation, as well as between medication load and FA in the left optic radiation. Decreased FA (P <.01) was observed in the left optic radiation and in the right anterothalamic radiation among subjects with BD taking vs those not taking mood stabilizers, as well as in the left optic radiation among depressed vs remitted subjects with BD. Subjects having BD with vs without lifetime alcohol or other drug abuse had significantly decreased FA in the left uncinate fasciculus. Conclusions: To our knowledge, this is the first study to use TBSS to examine WM in subjects with BD. Subjects with BD vs controls showed greater WM FA in the left OMPFC that diminished with age and with alcohol or other drug abuse, as well as reduced WM FA in the right OMPFC. Mood stabilizers and depressed episode reduced WM FA in left-sided sensory visual processing regions among subjects with BD. Abnormal right vs left asymmetry in FA in OMPFC WM among subjects with BD, likely reflecting increased proportions of left-sided longitudinally aligned and right-sided obliquely aligned myelinated fibers, may represent a biologic mechanism for mood dysregulation in BD.

Cardiovascular Risk and Clinical Factors in Athletes: 10 Years of Evaluation

DE MATOS, L. D. N. J., N. D. A. O. CALDEIRA, P. D. S. PERLINGEIRO, I. L. G. DOS SANTOS, C. E. NEGRAO and L. F. AZEVEDO. Cardiovascular Risk and Clinical Factors in Athletes: 10 Years of Evaluation. Med. Sci. Sports Exerc., Vol. 43, No. 6, pp. 943-950, 2011. Purpose: Preparticipation screening in athletes is a very current but controversial theme. Part of this controversy is due to the cost benefit, especially when the screening is merely used as a prevention of sudden cardiac death caused by rare and hereditary diseases. The purpose of this study was to describe the prevalence of preexisting diseases, cardiovascular risk factor for cardiovascular diseases development, and hematological profile in a population of amateur and professional athletes. Methods: Data of 623 athletes (529 men and 94 women), aged 13-77 yr, were analyzed to detect preexisting diseases. The variables total cholesterol, LDL, HDL, triglycerides, fasting glucose, body mass index, hemoglobin, hematocrit, and ferritin were analyzed in two groups according to age, that is, younger and older 35 yr old, and their prevalence (%) and distribution in quartiles were presented. chi(2) test and Pearson product-moment correlation coefficients between variables were applied, and P < 0.05 was adopted for significance. Results: Hypertension was the most prevalent preexisting diseases, although the data showed low prevalence of cardiomyopathy. Cardiovascular risk factors were prevalent in both genders. There were positive correlations between cardiovascular risk factors and age and between body mass index and lipid levels in male athletes. Also, there was a high prevalence of low ferritin levels for women, with positive correlation between the levels of hemoglobin and ferritin. Conclusions: In the present study, hypertension was the most prevalent diagnosed disease, and cardiovascular risk factors showed important prevalence, especially in athletes older than 35 yr. Although physical training represents a cardioprotective factor to the onset of cardiovascular disease, it does not exclude the prevalence of risk factors and diseases in athletes.

Risk factors across the life course and dementia in a Brazilian population: results from the Sao Paulo Ageing & Health Study (SPAH)

Background Several mechanisms have been suggested to explain the association between adversities across life and dementia. This study aimed to investigate the association between indicators of socioeconomic disadvantages throughout the life-course and dementia among older adults in Sao Paulo, Brazil and to explore possible causal pathways. Methods We used baseline data from the SPAH study which involved participants aged 65 years and older (n = 2005). The outcome of interest was prevalent dementia. Exposures included in the analyses were socioeconomic position (SEP) indicators in childhood (place of birth and literacy) and adulthood (occupation and income), anthropometric measurements as markers of intrauterine and childhood environment (head circumference and leg length), smoking, diabetes and hypertension. Logistic regression models were used to test the hypothesized pathways and to assess whether there was an association between cumulative adversities across the life course and prevalent dementia. Results Indicators of socioeconomic disadvantage in early life were associated with increased prevalence of dementia. This association was partially mediated through adulthood SEP. Head circumference and leg length were also clearly associated with dementia but there was no evidence that this association was mediated by early life socioeconomic disadvantage. There was an association between cumulative unfavourable conditions across the life course and dementia. Conclusions Early life disadvantages seem to operate through biological mechanisms associated with passive brain reserve and opportunities in life representing active cognitive reserve. Prevention of dementia should start early in life and continue through life span as seen with many other chronic diseases.

One-stage laparoscopic bisegmentectomy 7-8 and bisegmentectomy 2-3 for bilateral colorectal liver metastases

Bisegmentectomy 7-8 is feasible even in the absence of a large inferior right hepatic vein. To our knowledge, this operation has never been performed by laparoscopy. This study was designed to present video of pure laparoscopic bisegmentectomy 7-8 and bisegmentectomy 2-3 in one-stage operation for bilateral liver metastasis. A 67-year-old man with metachronous bilobar colorectal liver metastasis was referred for surgical treatment after neoadjuvant chemotherapy. CT scan disclosed two liver metastases: one located between segments 7 and 8 and another one in segment 2. At liver examination, another metastasis was found on segment 3. We decided to perform a bisegmentectomy 7-8 along with bisegmentectomy 2-3 in a single procedure. The operation began with mobilization of the right liver with complete dissection of retrohepatic vena cava. Inferior right hepatic vein was absent. Right hepatic vein was dissected and encircled. Upper part of right liver, containing segment 7 and 8, was marked with cautery. Selective hemi-Pringle maneuver was performed and right hepatic vein was divided with stapler. At this point, liver rotation to the left allowed direct view and access to the superior aspect of the right liver. Liver transection was accomplished with harmonic scalpel and endoscopic stapling device. Bisegmentectomy 2-3 was performed using the intrahepatic Glissonian approach. The specimens were extracted through a suprapubic incision. Liver raw surfaces were reviewed for bleeding and bile leaks. Operative time was 240 minutes with no need for transfusion. Recovery was uneventful. Patient was discharged on the fifth postoperative day. Patient is well with no evidence of disease 14 months after liver resection. Tumor markers are within normal range. Bisegmentectomy 7-8 may increase resectability rate in patients with bilateral lesions. This operation can be performed safely by laparoscopy. Preservation of segments 5 and 6 permitted simultaneous resection of segments 2 and 3 with adequate liver remnant.

Brain structure and symptom dimension relationships in obsessive-compulsive disorder: A voxel-based morphometry study

Background: Obsessive-compulsive disorder (OCD) is a clinically heterogenous disorder characterized by temporally stable symptom dimensions. Past inconsistent results from structural neuroimaging studies of OCD may have resulted from the effects of these specific symptom dimensions as well as other socio-demographic and clinical variables upon gray matter (GM) volume. Methods: GM volume was measured in 25 adult OCD patients and 20 adult healthy controls using voxel-based morphometry (VBM), controlling for age and total brain GM volume. Univariate and multivariate regression analyses were carried out between regions of GM difference and age, age of onset, medication load, OCD severity, depression severity, and separate symptom dimension scores. Results: Significant GM volumetric differences in OCD patients relative to controls were found in dorsal cortical regions, including bilateral BA6, BA46, BA9 and right BA8 (controls > patients), and bilateral midbrain (patients > controls). Stepwise regression analyses revealed highly significant relationships between greater total OCD symptom severity and smaller GM volumes in dorsal cortical regions and larger GM volumes in bilateral midbrain. Greater age was independently associated with smaller GM volumes in right BA6, left BA9, left BA46 and larger GM volumes in right midbrain. Greater washing symptom severity was independently associated with smaller GM volume in right BA6, while there was a trend association between greater hoarding symptom severity and lower GM volume in left BA6. Limitations: The sample was relatively small to examine the relationship between symptom scores and GM volumes. Multiple patients were taking medication and had comorbid disorders. Conclusions: These analyses suggest dorsal prefrontal cortical and bilateral midbrain GM abnormalities in OCD that appear to be primarily driven by the effects of total OCD symptom severity. The results regarding the relationship between GM volumes and symptom dimension scores require examination in larger samples. (C) 2008 Elsevier B.V. All rights reserved.

Constitutive nitric oxide synthase activation is a significant route for nitroglycerin-mediated vasodilation

The physiological effects of nitroglycerin as a potent vasodilator have long been documented. However, the molecular mechanisms by which nitroglycerin exerts its biological functions are still a matter of intense debate. Enzymatic pathways converting nitroglycerin to vasoactive compounds have been identified, but none of them seems to fully account for the reported clinical observations. Here, we demonstrate that nitroglycerin triggers constitutive nitric oxide synthase (NOS) activation, which is a major Source of NO responsible for low-dose (1-10 nM) nitroglycerin-induced vasorelaxation. Our studies in cell cultures, isolated vessels, and whole animals identified endothelial NOS activation as a fundamental requirement for nitroglycerin action at pharmacologically relevant concentrations in WT animals.

Presence of residual basal cell carcinoma in re-excised specimens is more probable when deep and lateral margins were positive

In order to quantify presence of residual BCC in patients with histologic positive margins after the first excison and to correlate the presence of residual tumor in re-excised lesions with the location of the positive margin on the first excision, a retrospective evaluation of 2053 surgically treated BCC was performed. Only 38.3% of the re-excised lesions showed residual tumor. In the group of re-excised lesions where residual BCC was found, 13% had lateral positive margin in the first excision, 39% had deep positive margin and 48% had both lateral and deep positive margins. In the group of re-excised lesions where no residual BCC was found, 49% of the primary excised lesions had lateral positive margin, 32% had deep positive margin and 19% had both deep and lateral positive margins. The association between residual tumor and positive margins was statistically significant (p = 0.01). Our findings confirm that presence of residual tumour is more likely when both lateral and deep margins are compromised.

Fatigue in amyotrophic lateral sclerosis: Frequency and associated factors

We aimed to quantify fatigue frequency and evolution in amyotrophic lateral sclerosis (ALS), and to correlate fatigue with factors such as age, sex, educational level, disease duration, functionality, quality of life, dyspnoea, depression and sleepiness. Sixty ALS patients (test group: TG) selected by El Escorial criteria and 60 normal individuals (control group: CG) matched according to sex and age, were followed every three months, during 9 months, by means of self-report scales: Fatigue Assessment Instrument (Fatigue Severity Scale plus three qualitative subscales); ALS Functional Rating Scale; McGill Quality of Life Questionnaire; dyspnoea analogical scale; Beck Depression Inventory and Epworth Sleepiness Scale. Fatigue was reported by 83% of TG (median: 3.6, interquartile range 1.5-5.4), compared with 20% of CG (median: 1, 1 - 1), and was significantly greater in the TG (p < 0.001, Mann-Whitney test). Fatigue severity increased by the ninth month of the study (p=0.0008, Friedman, Muller-Dunn post test). There was no correlation between fatigue and other parameters, except for an inverse correlation with age at disease onset (p=0.0395, Spearman rank correlation). In conclusion, fatigue was frequent in ALS, greater in the youngest patients and worsened during follow-up. Possibly, ALS related fatigue is an independent factor, which deserves individualized approach and treatment.

High prevalence of dementia among older adults from poor socioeconomic backgrounds in Sao Paulo, Brazil

Background: The aim of this study was to determine the prevalence of dementia in a socioeconomically disadvantaged population of older adults living in the city of Sao Paulo, Brazil. Methods: A cross-sectional one-phase population-based study was carried out among all residents aged >= 65 in defined census sectors of an economically disadvantaged area of Sao Paulo. Identification of cases of dementia followed the protocol developed by the 10/66 Dementia Research Group. Results: Of 2072 individuals in the study, 105 met the criteria for a diagnosis of dementia, yielding a prevalence of 5.1%. Prevalence increased with age for both men and women after age 75 years, but was stable from 65 to 74 years. Low education and income were associated with increased risk of dementia. Conclusions: The prevalence of dementia among older adults from low socioeconomic backgrounds is high. This may be partly due to adverse socioeconomic conditions and consequent failure to compress morbidity into the latter stages of life. The increasing survival of poorer older adults with dementia living in developing countries may lead to a rapid increase in the prevalence of dementia worldwide.

The effect of early virological response in health-related quality of life in HCV-infected patients

Twenty-nine HCV-infected patients were treated with pegylated interferon alpha. Diagnosis was based on serum HCV RNA-PCR positive results and liver biopsy. All patients had elevated serum levels of alanine aminotransferase at the time of the study, but liver disease was compensated. Patients were evaluated at baseline treatment and after 4 and 12 weeks of antiviral treatment with the Medical Outcomes Study 36-item Short-Form Health Survey. The Mini-International Neuropsychiatric Interview was used to exclude previous or current psychiatric diagnoses. Both patients and psychiatrists were blind to the HCV RNA status, and serum HCV RNA test results only became available after the visit at week 12. After antiviral treatment, 16 patients (55.2%) were classified as nonresponders and 13 (44.8%) were classified as responders. When compared to nonresponders, responders had a greater improvement in the HRQOL scores for the mental health domain (P<.019). Differences in other domains were not significant. The present study confirms that active viral infection is one possible reason for the poor Health-Related Quality of Life in this population.

Oxidant generation predominates around calcifying foci and enhances progression of aortic valve calcification

Objective - We hypothesized that reactive oxygen species ( ROS) contribute to progression of aortic valve ( AV) calcification/ stenosis. Methods and Results - We investigated ROS production and effects of antioxidants tempol and lipoic acid ( LA) in calcification progression in rabbits given 0.5% cholesterol diet +10(4) IU/d Vit.D-2 for 12 weeks. Superoxide and H2O2 microfluorotopography and 3-nitrotyrosine immunoreactivity showed increased signals not only in macrophages but preferentially around calcifying foci, in cells expressing osteoblast/ osteoclast, but not macrophage markers. Such cells also showed increased expression of NAD(P) H oxidase subunits Nox2, p22phox, and protein disulfide isomerase. Nox4, but not Nox1 mRNA, was increased. Tempol augmented whereas LA decreased H2O2 signals. Importantly, AV calcification, assessed by echocardiography and histomorphometry, decreased 43% to 70% with LA, but increased with tempol (P <= 0.05). Tempol further enhanced apoptosis and Nox4 expression. In human sclerotic or stenotic AV, we found analogous increases in ROS production and NAD(P) H oxidase expression around calcifying foci. An in vitro vascular smooth muscle cell (VSMC) calcification model also exhibited increased, catalase-inhibitable, calcium deposit with tempol, but not with LA. Conclusions - Our data provide evidence that ROS, particularly hydrogen peroxide, potentiate AV calcification progression. However, tempol exhibited a paradoxical effect, exacerbating AV/vascular calcification, likely because of its induced increase in peroxide generation.

Ultrasound findings in infantile systemic hyalinosis

To describe clinical and ultrasound findings in a patient with infantile systemic hyalinosis (ISH). A 5-month-old boy was evaluated of joint contractures. In addition to clinical and laboratory investigations, an ultrasound of his joints was done and compared to a child with similar age. On examination, a short neck, gingival hyperplasia and papular rash were noted. Joint examination showed painful passive movement, reduced range of motion, and joint contractures in knees, elbows, and small joints of the hands, without any evidence of synovial thickness. Ultrasound of the affected joints showed irregular cortical surface of MCPs and PIP, the presence of osteophytes and bone erosions, increased synovial fluid without evidence of synovial hyperplasia. This is the first report to show evidence of US findings in ISH. Ultrasound findings may help to distinguish ISH from JIA in early stages.

Social dysfunction in bipolar disorder: pilot study

Objective: The purpose of the present study was to assess the social skills of euthymic patients with bipolar disorder. Methods: A group of 25 outpatients with bipolar disorder type I were evaluated in comparison with a group of 31 healthy volunteers who were matched in terms of level of education, age, sex and intelligence. Both groups were assessed using a self-report questionnaire, the Brazilian Inventario de Habilidades Sociais (IHS, Social Skills Inventory). Two Wechsler Adult Intelligence Scale subtests ( Picture Arrangement and Comprehension) were also used in order to assess subject ability to analyse social situations and to make judgements, respectively. Results: Patients with bipolar disorder had lower IHS scores for the domains that assessed conversational skills/social self-confidence and social openness to new people/situations. Patients with anxiety disorders had high scores for the domain that assessed self-confidence in the expression of positive emotions. No differences were found between patients and controls in performance on the Wechsler Adult Intelligence Scale Picture Arrangement and Comprehension subtests. Conclusions: Euthymic patients with bipolar disorder present inhibited and overattentive behaviour in relation to other people and their environment. This behaviour might have a negative impact on their level of social functioning and quality of life.
