Safety Profile of Methylphenidate Under Long-Term Treatment in Adult ADHD Patients – Results of the COMPAS Study
2020
Abstract Introduction The Comparison of Methylphenidate and Psychotherapy in adult ADHD Study (COMPAS) was a prospective, randomized multicenter clinical trial, comparing methylphenidate (MPH) with placebo (PLAC) in combination with cognitive behavioral group psychotherapy (GPT) or individual clinical management (CM) over the period of 1 year. Here, we report results on treatment safety. Methods MPH and PLAC were flexibly dosed. Among 433 randomized patients, adverse events (AEs) were documented and analyzed on an “as received” basis during week 0–52. Electrocardiogram data were recorded at baseline and week 24. Results Comparing 205 patients who received ≥1 dose of MPH with 209 patients wh…
The effect of an 1100 km run on testicular, adrenal and thyroid hormones
1984
Although endocrine effects of physical or psychological stress are well documented, it is not known to what extent adaptation to prolonged exertion occurs. We therefore investigated the impact of an 1100 km run of 20 days' duration on selected pituitary, testicular, adrenal and thyroid hormones. Blood samples were obtained from five male athletes prior to and after the day's run on the 1st, 5th, 9th, 14th and 19th day. Results show that adrenal and thyroid function soon adapt to the daily strain. Testosterone levels, however, were markedly decreased throughout the 20 days while LH levels remained unchanged. Thus it appears that the reproductive endocrine system is more susceptible to long-t…
Exogenous and endogenous provocation of psoriasis. A contribution to the Koebner phenomenon.
1974
Previous literature reports as well as own investigations concerning exogenously and endogenously induced Koebner-reactions in psoriatics are presented. The time interval between irritation and the Koebner-reaction is emphasized. It is proposed, that the intensity of the psoriatic reaction is mediated by circulating DHEA-deficiency. Hypothetical models are presented which allow to explain the different developmental rates of psoriatic lesions in relation to the type of irritation, the area affected and the subsequent proliferative responses.
Economic aspects of different muscle relaxant regimens.
2000
Objective At a time of cost reduction in medical care efforts to manage the ever-increasing costs of new pharmaceutical drugs become increasingly important. Costs of four different muscle relaxant regimens including the new intermediate-acting neuromuscular blocking drugs (NMBD) cisatracurium and rocuronium will be analyzed. Methods Eighty patients undergoing laparoscopic cholecystectomy were prospectively studied. All patients received standardized general anaesthesia with desflurane/fentanyl. Muscle relaxation was achieved with atracurium, cisatracurium, vecuronium, or rocuronium with 20 patients in each group. Intraoperatively muscle relaxants were added to maintain two twitches of the t…
Epidemiology of the sarcomas of the jaws in a Peruvian population
2010
Objective: Analysis of the clinical characteristics of patients with Sarcomas of the Jaws treated in the “Instituto Nacional de Enfermedades Neoplasicas. Dr. Eduardo Caceres Graziani” from 1952-2007. Study Design: Review of 155 clinical records of patients with Sarcomas of the Jaws and record of age, gender, size, location, clinical symptoms and signs, histopathological diagnoses and type of treatment. The data obtained were analyzed by means of Student’s statistical t-test, Fisher and Friedman’s test. Results: Analysis of 155 Sarcomas of the Jaws. The average age of patients was 36.8 years old (range: 1-80 years); the female gender was the most frequent (52.9%); the average tumor size was …
Responsiveness of human neonates to the odor of 5alpha-androst-16-en-3-one: A behavioral paradox?
2014
The odorous steroid 5alpha-androst-16-en-3-one (AND) occurs in numerous biological fluids in mammals, including man, where it is believed to play a chemocommunicative role. As AND was recently detected in milk and amniotic fluid, sensitivity and hedonic responses to this substance were assessed in human neonates. To this aim, respiration and facial expressions were recorded in 3-day-old newborns in response to aqueous solutions of AND, ranging from 500ng/mL to 0.5 fg/mL. Although analyses of respiratory rate did not lead to clear-cut results, the newborns changed their facial expressions at concentrations not detected by adults in a triangle test. Newborns displayed negative facial actions …
MRI radiomics-based machine-learning classification of bone chondrosarcoma.
2019
Abstract Purpose To evaluate the diagnostic performance of machine learning for discrimination between low-grade and high-grade cartilaginous bone tumors based on radiomic parameters extracted from unenhanced magnetic resonance imaging (MRI). Methods We retrospectively enrolled 58 patients with histologically-proven low-grade/atypical cartilaginous tumor of the appendicular skeleton (n = 26) or higher-grade chondrosarcoma (n = 32, including 16 appendicular and 16 axial lesions). They were randomly divided into training (n = 42) and test (n = 16) groups for model tuning and testing, respectively. All tumors were manually segmented on T1-weighted and T2-weighted images by drawing bidimensiona…
Botulinum toxin A (Botox) and sweating-dose efficacy and comparison to other BoNT preparations.
2004
Abstract Background Botulinum toxin type A (BoNT/A) is 20–50 times more effective than Botulinum toxin type B (BoNT/B) concerning the treatment of muscular hypercontractions [Sloop, R.R., Cole, B.A., Escutin, R.O., 1997. Human response to botulinum toxin injection: type B compared with type A. Neurology 49, 189–194]. Botulinum toxins block motor nerves as well as autonomic fibres [Rand, M.J., Whaler, B.C., 1965. Impairment of sympathetic transmission by botulinum toxin. Nature 206, 588–591]. Objective Purpose of this study was to analyse the dose dependent reduction of sweating using the BoNT/A preparation Botox® and to compare the results with our earlier results analysing Dysport® [Braune…
Augmented glucose-6-phosphate dehydrogenase activity and normal penetration and metabolism of dehydroepiandrosterone in mononuclear leukocytes in pso…
1986
The aim of the study was to determine a biochemical basis for the augmented oxidative metabolism found in mononuclear leukocytes (MNL) of patients with active psoriasis. Dehydroepiandrosterone (DHEA) is known to inhibit glucose-6-phosphate dehydrogenase (G-6-PDH). We determined the activity of G-6-PDH as well as the penetration and metabolism of DHEA - diminished plasma concentrations of which have been found in psoriatics previously - in 16 patients with active psoriasis and 16 controls. MNL in patients with psoriasis possessed 52% more (p less than 0.05) G-6-PDH activity, based on cell number, and 34% more (p less than 0.05) activity, based on soluble protein. No difference in DHEA penetr…
Alterations in androgen conjugate levels in women and men with alopecia.
1994
Objective To assess levels of androgen metabolites thought to reflect, at least in part, peripheral androgen activity in women with androgenic alopecia and men with premature balding in an effort to determine if a common abnormality exists. Design Prospective study in various groups of women and men. Setting Reproductive Endocrine Clinic at our university medical center. Patients Ten normal ovulatory female controls and 50 hyperandrogenic women divided on the basis of hirsutism and alopecia as follows: [1] 8 hirsute women with androgenic alopecia; [2] 12 nonhirsute women with androgenic alopecia; [3] 18 hirsute women without androgenic alopecia; and [4] 12 nonhirsute women without androgeni…
