    To determine whether an anabolic steroid had any benefit in the treatment of rheumatoid arthritis 47 patients entered a parallel group study. Twenty four received nandrolone decanoate 50 mg intramuscularly every third week for two years and 23 patients received no anabolic steroids. Other therapy was unaltered. Patients attended for clinical and biochemical assessments as well as the objective assessments of elementary body composition by in vivo neutron activation analysis and measurement of the mineral content of the distal femur by single photon absorptiometry on five occasions. A modest clinical deterioration (except for grip strength) was seen in both groups. No significant changes in calcium or alkaline phosphatase were seen. There was no significant change in total body calcium, total body phosphorus, body weight, or bone index/bone width measurements in either group. Significant increases occurred in total body nitrogen, total body potassium, haemoglobin, and packed cell volume (by six months) in the group treated with nandrolone decanoate. Comparison of 10 patients in the group treated with nandrolone decanoate also receiving oral steroid therapy with 14 patients in this group not receiving oral steroid therapy showed no significant differences. The main side effect of nandrolone decanoate was hoarseness. No radiological changes were seen. Nandrolone decanoate, in a dose that produces a significant anabolic effect, has no demonstrable action on bone metabolism in rheumatoid arthritis but may improve the chronic anaemia by six months.

    The effects of anabolic-androgenic steroid administration on the function of the sarcoplasmic reticulum (SR) pump were investigated in chemically skinned fibres from the extensor digitorum longus (EDL) and soleus muscles of sedentary rats. Twenty male rats were divided into two groups, one group received an intramuscular injection of nandrolone decanoate (15 mg x kg(-1)) weekly for 8 weeks, the second received similar weekly doses of vehicle (sterile peanut oil). Compared with control muscles, nandrolone decanoate treatment reduced SR Ca(2+) loading in EDL and soleus fibres by 49% and 29%, respectively. In control and treated muscles, the rate of Ca(2+) leakage depended on the quantity of Ca(2+) loaded. Furthermore, for similar SR Ca(2+) contents, the Ca(2+) leakage rate was not significantly modified by nandrolone decanoate treatment. Nandrolone decanoate treatment thus affects Ca (2+) uptake by the SR in a fibre-type dependent manner.

    It has been reported that nandrolone decanoate is helpful in overcoming the neutropenic phase following irradiation. In the present study the influence of nandrolone decanoate on the thymus' cellularity after total body irradiation was investigated. In comparison with a placebo-treated group, mice receiving nandrolone decanoate showed a similar pattern of thymus repopulation, but a significantly lower number of thymocytes over the whole period of treatment was found. Nonirradiated mice also had a significantly lower number of thymocytes when treated with nandrolone decanoate. In addition, the number of circulating leukocytes was also evaluated over a period of 1 month after total body irradiation. On 11 of the 21 days investigated, a significantly higher number of leukocytes was found in the nandrolone decanoate-treated group. We conclude that the action of nandrolone decanoate was not clearly distinct from that of testosterone regarding either granulopoiesis or thymic involution.

    Abuse of anabolic androgenic steroids is linked to a variety of cardiovascular complications. The aim of our study was to investigate the possible cardiovascular effects of nandrolone decanoate on young rabbits using echocardiography, histology and monitoring of telomerase activity, oxidative stress and biochemical markers. Fourteen rabbits were divided into three administration groups and the control group. Doses of 4mg/kg and 10mg/kg of nandrolone decanoate, given intramuscularly and subcutaneously, two days per week for six months were applied. A 4-months wash-out period followed. Focal fibrosis and inflammatory infiltrations of cardiac tissue were observed in the high dose groups. Thiobarbituric acid-reactive species (TBARS) levels were significantly increased in the high dose groups, while catalase activity decreased. Myocardial Performance Index (MPI) is the main echocardiographic index primarily affected by nandrolone administration in rabbits. Despite the preserved systolic performance, histological lesions observed associated with distorted MPI values, point to diastolic impairment of the thickened myocardium due to nandrolone treatment. Oxidative stress accumulates and telomerase activity in cardiac tissue rises. Subcutaneous administration seems to be more deleterious to the cardiovascular system, as oxidative stress, telomerase activity and biochemical markers do not appear to return into normal values in the wash-out period.

    This study tested the hypothesis that different doses of nandrolone decanoate (ND) will cause changes in the estrous cycle and ovarian tissue of adult rats; and investigated the duration of the recovery period that is sufficient to restore the damage in the animals treated with different doses. Wistar rats were treated with ND at doses of 1.87, 3.75, 7.5 and 15 mg/kg body weight, or received mineral oil (control group) for 15 days, subcutaneously. All animals were divided into three groups according to the treatment periods: (i) ND treatment for 15 days; (ii) ND treatment followed by a 30-day recovery; and (iii) ND treatment followed by a 60-day recovery. Estrous cycle was monitored daily, and at the end of each period, the animals were euthanized for histopathological analysis. During ND treatment and after 30-day recovery, all animals exhibited persistent diestrus. After a 60-day recovery, persistent diestrus was only maintained in the group that had received the highest dose. Ovarian weight was decreased significantly after the 30-day recovery, regardless of ND doses, compared with the control group. There was a reduction (P < 0.05) in the number of corpora lutea and antral and growing follicles, in contrast to an increase (P < 0.05) in atretic follicles in a dose- and time-dependent manner. Remarkable histopathological changes occurred in the ovaries of all ND-treated groups. In conclusion, the different doses of ND caused changes in the estrous cycle and ovarian tissue of rats, and recovery periods (30 and 60 days) were insufficient to completely restore the damage in the animals treated with the highest dose.

    Nandrolone is included in the class II of anabolic androgenic steroids (AAS) which is composed of 19-nor-testosterone-derivates. In general, AAS is a broad and rapidly increasing group of synthetic androgens used both clinically and illicitly. AAS in general and nandrolone decanoate (ND) in particular have been associated with several behavioral disorders. The purpose of this review is to summarize the literature concerning studies dealing with ND exposure on animal models, mostly rats that mimic human abuse systems (i.e. supraphysiological doses). We have focused in particular on researches that have investigated how ND alters the function and expression of neuronal signaling molecules that underlie behavior, anxiety, aggression, learning and memory, reproductive behaviors, locomotion and reward.

    Among the various side effects of supra-physiological dose of anabolic androgenic steroids that are described, renal toxicity remains the least evaluated. The present study provides evidence that long-term administration of nandrolone decanoate could lead to alterations of renal function and structure in the experimental rabbit model. A pronounced increase in serum urea, creatinine, SGOT and SGPT is observed in the treated animals, with intramuscular administration being more detrimental. Histopathological evaluation of kidneys indicated hyperaemia, fibrosis and focal inflammation. Furthermore, the significantly increased telomerase activity found in the kidneys of the intramuscularly treated animals could possibly represent a counteracting survival mechanism. Oxidative stress markers that were influenced the most were TBARS, indicating lipid peroxidation, and GSH. An interesting finding in our study though, was that while intramuscular administration showed the highest biochemical derangement, oxidative stress markers provided mixed results between intramuscularly and subcutaneously treated rabbits. In conclusion, nephrotoxicity of nandrolone decanoate remains a multi-factorial, partly irreversible effect that involves augmented tissue oxidative status. PMID:27346656

    Anabolic-androgenic steroids are used at high doses by athletes for improving athletic ability, physical appearance and muscle mass. Unfortunately, the abuse of these agents has significantly increased. It has been established that exercise and high doses of anabolic-androgenic steroids may influence the hypothalamic-pituitary-gonadal axis, which can in turn affect testicular apoptosis. However, the effect of the combination of exercise and high dose of anabolic-androgenic steroids on testicular apoptosis is not known. We investigated the combined effects of exercise and high doses of nandrolone decanoate on apoptosis in the spermatogenic cell lineage. Five groups of male Wistar strain albino rats were treated as follows for 8 weeks: solvent of nandrolone decanoate (peanut oil) as a vehicle (Sham); nandrolone decanoate (10 mg/kg/weekly) (nandrolone decanoate); exercise (1 hr/day, 5 days a week) (exercise); nandrolone decanoate (10 mg/kg/weekly) and exercise (1 hr/day, 5 days a week) (nandrolone decanoate exercise); and sedentary control without any injection or exercise (Control). Apoptosis in the male germ line was characterized by TUNEL, caspase-3 assay and transmission electron microscopy. The weights of the testis and accessory sex organs, as well as sperm parameters significantly decreased in the experimental groups relative to the sham and control groups (p < or = 0.05). Germ cell apoptosis and a significant decrease in the number of germ cell layers in nandrolone decanoate exercise-treated testes were observed (p < or = 0.05). Exercise training seems to increase the extent of apoptotic changes caused by supraphysiological dose of nandrolone decanoate in rats, which in turn affects fertility.

    In a series of four separate experiments, the effects of anabolic-androgenic steroid (AAS) compounds on the estrous cycle of adult Long-Evans rats were examined. Sexual receptivity, vaginal cytology, and body weight were monitored throughout a 2-week baseline, AAS treatment, and recovery periods. In Experiments 1-3, subjects were administered 17 alpha-methyltestosterone, methandrostenolone, or nandrolone decanoate at doses selected to mimic the human abuse levels of each compound. In these studies, the highest doses of 17 alpha-methyltestosterone (7.5 mg/kg) and nandrolone decanoate (5.6 mg/kg) disrupted behavioral and vaginal cyclicity, whereas the highest dose of methandrostenolone (3.75 mg/kg) appeared to have slightly less robust effects. To compare effects on estrous cyclicity across AAS compounds, subjects in Experiment 4 received a single high dose (7.5 mg/kg) of each compound for 2 weeks. At this dose, all AAS compounds interfered with vaginal cyclicity, although effects on behavioral cyclicity and uterine weight were not uniform. Across all 4 experiments, AAS effects on body weight were minimal. The short-term administration of AAS compounds at levels commonly used by humans disrupts female neuroendocrine function in a dose-dependent manner. PMID:9035257

    The ability of an anabolic steroid, nandrolone decanoate, to increase committed topoietic stem cell (CFU-gm, CFU-e, and BFU-e) colony formation after sublethal irradiation was evaluated. Immediately after receiving whole body irradiation and on the next two days, each mouse was injected intraperitoneally with nandrolone decanoate (1.25 mg) in propylene glycol. Irradiated control mice received only propylene glycol. Compared to controls, drug-treated mice showed marked peripheral blood leukocytosis and more stable packed red cell volume. Drug-treated mice also demonstrated increased erythropoiesis, as CFU-e/BFU-e concentrations from both marrow (9% to 581%) and spleen (15% to 797%) were elevated. Granulopoiesis was increased similarly, as CFU-gm concentrations from marrow (38% to 685%) and spleen (9% to 373%) were elevated. These results demonstrate that nandrolone decanoate enhances hematopoietic stem cell recovery after sublethal whole body irradiation. This suggests that following hematopoietic suppression, nandrolone decanoate may stimulate the recovery of hematopoiesis at the stem cell level and in peripheral blood.

    Anabolic androgenic steroids (AAS) are known as doping agents within sports and body-building, but are currently also abused by other groups in society in order to promote increased courage and aggression. We previously showed that 14 days of daily intramuscular injections of the AAS nandrolone decanoate (15 mg/kg) reduced the extracellular levels of the dopaminergic metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) in the nucleus accumbens shell using microdialysis. The aim of the present study was to investigate whether the same dose regimen of nandrolone decanoate may affect the activities of the dopamine-metabolizing enzymes monoamine oxidases A and B (MAO-A and MAO-B). A radiometric assay was used to determine the activities of MAO-A and MAO-B in rat brain tissues after 14 days of daily i.m. nandrolone decanoate injections at the doses 3 and 15 mg/kg. Gene transcript contents of MAO-A, MAO-B and cathecol-O-methyltransferase (COMT) were measured with quantitative real-time reverse transcription PCR. 3 mg/kg of nandrolone decanoate significantly reduced the activity of both MAO-A and -B in the caudate putamen. 15 mg/kg of nandrolone decanoate significantly reduced the activity of MAO-A in the amygdala and increased the gene transcript level of MAO-B in the substantia nigra. In conclusion, imbalanced MAO activities may contribute to explain the impulsive and aggressive behaviour often described in AAS abusers. The reduced MAO activities observed are in line with our previously presented findings of decreased extracellular levels of DOPAC and HVA in the rat brain, indicating decreased monoaminergic activity following repeated AAS administration.

    Nandrolone decanoate, an anabolic androgen steroid (AAS) illicitly used by adult and adolescent athletes to enhance physical performance and body image, induces psychiatric side effects, such as aggression, depression as well as a spectrum of adverse physiological impairments. Since adolescence represents a neurodevelopmental window that is extremely sensitive to the detrimental effects of drug abuse, we investigated the long-term behavioral and neurophysiological consequences of nandrolone abuse during adolescence. Adolescent rats received daily injections of nandrolone decanoate (15 mg/kg, i.m.) for 14 days (PND 40-53). At early adulthood (PND 68), forced swim, sucrose preference, open field and elevated plus maze tests were performed to assess behavioral changes. In vivo electrophysiological recordings were carried out to monitor changes in electrical activity of serotonergic neurons of the dorsal raphe nucleus (DRN) and noradrenergic neurons of the locus coeruleus (LC). Our results show that after early exposure to nandrolone, rats display depression-related behavior, characterized by increased immobility in the forced swim test and reduced sucrose intake in the sucrose preference test. In addition, adult rats presented anxiety-like behavior characterized by decreased time and number of entries in the central zone of the open field and decreased time spent in the open arms of the elevated plus maze. Nandrolone decreased the firing rate of spontaneously active serotonergic neurons in the DRN while increasing the firing rate of noradrenergic neurons in the LC. These results provide evidence that nandrolone decanoate exposure during adolescence alters the emotional profile of animals in adulthood and significantly modifies both serotonergic and noradrenergic neurotransmission.

    We examined the influence of chronic administration of nandrolone decanoate with low-intensity endurance swimming exercise on susceptibility to lethal ventricular arrhythmias in rat. The animal groups included the control group, exercise group (EX), nandrolone group (Nan), vehicle group (Arach), trained vehicle group (Arach + Ex) and trained nandrolone group (Nan + Ex) that treated for 8 weeks. Then, arrhythmia induction was performed by intravenous infusion of aconitine and electrocardiogram recorded. Then, malondialdehyde (MDA), hydroxyproline (HYP) and glutathione peroxidase of heart tissue were measured. Chronic administration of nandrolone with low-intensity endurance swimming exercise had no significant effect on blood pressure, heart rate and basal ECG parameters except RR interval that showed increase (P < 0.05). Low-intensity exercise could prevent the incremental effect of nandrolone on MDA and HYP significantly. It also increased the heart hypertrophy index (P < 0.05) and reduced the abating effect of nandrolone on animal weighting. Nandrolone along with exercise significantly increased the duration of VF (P < 0.05) and reduced the VF latency (P < 0.05). The findings suggest that chronic co-administration of nandrolone with low-intensity endurance swimming exercise to some extent facilitates the occurrence of ventricular fibrillation in rat. Complementary studies are needed to elucidate the involved mechanisms of this abnormality. PMID:25636207

    Growth hormone (GH) and anabolic androgenic steroids (AAS) are commonly used in sports communities. Several studies have suggested an association between GH and AAS. We have investigated the impact of GH in rats treated with nandrolone decanoate (ND). Male Wistar rats received ND (15 mg/kg) every third day during three weeks and were subsequently treated with recombinant human GH (1.0I U/kg) for ten consecutive days. Plasma samples were collected and peripheral organs (i.e. heart, liver, testis and thymus) were dissected and weighed. Concentration of thirteen endogenous steroids was measured in the rat plasma samples using high specificity LC-MS/MS methods. Seven steroids were detected and quantified, and concentrations of estrone, testosterone, and androstenedione were significantly different among the groups, while concentrations of pregnenolone, DHEA, 17-hydroxyprogesterone and corticosterone were not altered. Administration of rhGH alone altered the plasma steroid distribution, and the results demonstrated significantly increased concentrations of plasma estrone as well as decreased concentrations of testosterone and androstenedione in the ND-treated rats. Administration of rhGH to ND-pretreated rats did not reverse the alteration of the steroid distribution induced by ND. Administration of ND decreased the weight of the thymus, and addition of rhGH did not reverse this reduction. However, rhGH administration induced an enlargement of thymus. Taken together, the plasma steroid profile differed in the four groups, i.e. control, AAS, rhGH and the combination of AAS and rhGH treatment.

    Age is a key factor in the development of prostatic lesions. An increase in reactive oxygen species levels occurs during aging. Furthermore, the indiscriminate use of anabolic androgenic steroids and physical exercise alter the availability of hormones and may promote the appearance of lesions. This study examined whether the use of nandrolone decanoate (ND), associated or not with resistance exercise training, affects the pathways related to the inflammatory response in the ventral prostate of adult and aged rats. Sprague-Dawley rats were distributed into eight experimental groups: sedentary with ND, sedentary without ND, exercise with ND, and exercise without ND. The animals performed resistance exercise training and received ND two times/week (5 mg/kg, i.m.) for 8 weeks. Adult rats were killed immediately following treatment completion, and aged rats remained untreated until reaching 300 days of age. The adult animals that received ND and performed resistance exercise training showed a higher occurrence of lesions with TLR4 activation. Marked IL-6 expression occurred in the group that performed resistance exercise training. The group exposed to ND showed overexpression of TLR2, TLR4, NOX1, Nrf2, TNF-α, and P38MAPK. The animals that received ND and performed training showed increase levels of NFκB, IRF3, IL-6, TNF-α, and NOX1. TLR2 and TLR4 showed no upregulation in the aged animals. The groups exercise + ND showed lesions in the adult stage and after aging, followed by molecular alterations. We concluded that nandrolone decanoate and resistance exercise training can promote the onset of prostatic tumors in the adult stage, and during aging, activating pathways involved in the inflammatory response.

    This study evaluated the effects of nandrolone associated with resistance training (RT) on cardiac cytokines, angiotensin-converting enzyme activity (ACEA), and the sensitivity of the Bezold-Jarisch reflex (BJR). Male Wistar rats were divided into 3 groups: CONT (received vehicle, no training); EXERC (RT: after one week of water adaptation, rats were exercised by jumping into water twice a week for 4 weeks), and ND+EXERC (received nandrolone decanoate 10 mg/kg, twice/week, i.m, associated with RT). The BJR was analysed by measuring bradycardic and hypotensive responses elicited by serotonin administration. Myocyte hypertrophy and matrix collagen deposition were determined by morphometric analysis of H&E and picrosirius red-stained samples, respectively. TNF-α and ACEA were also studied. RT promoted physiological myocyte hyrpertrophy but did not cause changes in the other parameters. The association of ND with RT increased myocyte hypertrophy, deposition of matrix type I collagen, TNF-α and ACEA; decreased IL-10, and impairment in the BJR were observed in ND+EXERC compared with CONT and EXERC. ND is associated with alterations in cardiac structure and function as a result of the development of pathological cardiac hypertrophy (cardiac cytokine imbalance, elevation of ACEA) and cardiac injury, even when combined with resistance training.

    BACKGROUND Anabolic-androgenic steroids have been associated with several side effects range. This experimental study was conducted to evaluate the effects of nandrolone decanoate (ND, an anabolic steroid) on lipid profile and liver enzymes in rats in Iran. METHODS Forty adult male and female of Wistar strain rats were randomly assigned to four groups of 10 animals each: male control, female control, ND-male treated (15 mg/kg b.w./day), and ND-female treated (15 mg/kg b.w./day). Serum concentrations of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were measured in all studied groups. RESULTS Treating rats with ND (case group) resulted in a significant elevation of TC (69.4 ± 8.7), TG (101.6 ± 32.9) and ALT (72.2 ± 13.8) and significant reduction of LDL (6.4 ± 2.6) and AST (138.7 ± 19.4) as compared to control group in female rats. ND supplementation (case group) significantly increased TC (64.4 ± 6.2), AST (255.0 ± 32.0), and ALT (84.3 ± 3.8) in comparison with the control group in male rats. CONCLUSION Overall, our result indicated that the ND use can cause a negative effect on lipid profile and liver enzyme in rats. PMID:26478734

    Background: Nandrolone decanoate (ND) is an anabolic androgenic steroid (AAS) which influences the ovarian structure and function. We assessed the effects of ND on the ovarian volume, number of primordial follicles, and level of hormones and also evaluated the modulatory effects of gonadotropins on the histopathological changes imposed by the administration of ND. Methods: Six groups of Sprague-Dawley adult female rats (n=30) were used. The experimental rats were injected intraperitoneally with 3 and 10 mg/kg ND with or without human menopausal gonadotropin (hMG), 10 IU weekly for one month. The vehicle and control rats were administered olive oil and saline, respectively, for the same period of time. The ovarian volume and number of primordial follicles were estimated by stereological methods. Results: The results showed a decrease in the ovarian volume, number of primordial follicles, and level of gonadotropins in the ND-treated animals compared with the vehicle groups. In the rats treated with 3 mg/kg of ND with hMG, an increase in the ovarian volume and number of primordial follicles was shown as compared to the rats treated with the same dose of ND without hMG. Conclusion: ND exerted detrimental effects on the dimensions of the ovary, number of follicles, and level of sex hormones. However, hMG, prevented the harmful effects of ND (at least in a low dose) on the ovarian follicles. PMID:24453393

    For the past 40 years, anabolic-androgenic steroids have been used by a wide variety of athletes with the hope of improving their training, endurance, and performance. The aim of this study was to examine the chronic effects of nandrolone decanoate (20 mg/kg, s.c, Deca-Durabolin DECA(®)) on oxidative stress biomarkers in the hearts of sedentary and exercised rats. The male Wistar albino rats (n = 180, four groups with three subgroups, 15 per subgroup, age 10 weeks, body mass 200-220 g) were sacrificed, and in the collected samples of blood, the following markers of oxidative stress were measured spectrophotometrically: (1) index of lipid peroxidation (measured as TBARS-thiobarbituric acid reactive substances); (2) nitrites (NO2 (-)); (3) hydrogen peroxide (H2O2); (4) superoxide anion radical (O2 (-)), and superoxide dismutase, catalase, and glutathione reductase. The results clearly show that the impact of ND alone, or in combination with physical training in general, is mildly pro-oxidative. The chronic physical training probably induces the protective antioxidant enzyme system , which may be of clinical interest when faced with overdosage of this drug. PMID:26361780

    The wide abuse of the anabolic steroid nandrolone decanoate by athletes and adolescents for enhancement of sporting performance and physical appearance may be associated with testicular toxicity and infertility. On the other hand, taurine; a free β-amino acid with remarkable antioxidant activity, is used in taurine-enriched beverages to boost the muscular power of athletes. Therefore, the purpose of this study was to investigate the mechanisms of the possible protective effects of taurine on nandrolone decanoate-induced testicular and sperm toxicity in rats. To achieve this aim, male Wistar rats were randomly distributed into four groups and administered either vehicle, nandrolone decanoate (10 mg/kg/week, I.M.), taurine (100 mg/kg/day, p.o.) or combination of taurine and nandrolone decanoate, for 8 successive weeks. Results of the present study showed that taurine reversed nandrolone decanoate-induced perturbations in sperm characteristics, normalized serum testosterone level, and restored the activities of the key steroidogenic enzymes; 3β-HSD, and 17β-HSD. Moreover, taurine prevented nandrolone decanoate-induced testicular toxicity and DNA damage by virtue of its antioxidant, anti-inflammatory, and anti-apoptotic effects. This was evidenced by taurine-induced modulation of testicular LDH-x activity, redox markers (MDA, NO, GSH contents, and SOD activity), inflammatory indices (TNF-α, ICAM-1 levels, and MMP-9 gene expression), intrinsic apoptotic pathway (cytochrome c gene expression and caspase-3 content), and oxidative DNA damage markers (8-OHdG level and comet assay). In conclusion, at the biochemical and histological levels, taurine attenuated nandrolone decanoate-induced poor sperm quality and testicular toxicity in rats. - Highlights: • Nandrolone decanoate (ND) disrupts sperm profile and steroidogenesis in rats. • ND upregulates gene expression of inflammatory and apoptotic markers. • Taurine normalizes sperm profile and serum testosterone level

    Elite athletes, body builders and adolescents misuse anabolic-androgenic steroids (AAS) in order to increase muscle mass or to enhance physical endurance and braveness. The high doses misused are associated with numerous adverse effects. The purpose of this study was to evaluate the impact of chronic supratherapeutic AAS treatment on circulating hormones and gene expression in peripheral tissues related to such adverse effects. Quantitative real-time PCR was used to measure expression levels of in total 37 genes (including peptide hormones, cell membrane receptors, nuclear receptors, steroid synthesising enzymes and other enzymes) in the pituitary, testes, adrenals, adipose tissue, kidneys and liver of male Sprague-Dawley rats after 14-day administration of the AAS nandrolone decanoate, 3 or 15 mg/kg. Plasma glucose and levels of adrenocorticotropic hormone (ACTH), adiponectin, corticosterone, ghrelin, insulin and leptin were also measured. We found several expected effects on the hypothalamic-pituitary-gonadal axis, while the treatment also caused a number of other not previously identified changes in circulating factors and gene transcription levels such as the dose-dependent reduction of the beta(3)-adrenergic receptor in adipose tissue, reduction of both circulating and mRNA levels of adiponectin, up-regulation of both hydroxymethylglutaryl-CoA-reductase, the rate-limiting enzyme in de novo synthesis of cholesterol, and the receptor for ACTH in the adrenals. The results provide evidence for wide ranging effects of AAS on the hypothalamic-pituitary-adrenal axis, adipose tissue and substrates of the renal control of blood pressure.

    The use of the anabolic androgenic steroid nandrolone and its prohormones is prohibited in sport. A common route of nandrolone administration is intramuscular injections of a nandrolone ester. Here we have investigated the detection time of nandrolone and 19-norandrosterone and 19-noretiocholanolone metabolites in eleven healthy men after the administration of a 150 mg dose of nandrolone decanoate. The urinary concentrations of nandrolone and the metabolites were monitored by GC-MS/MS for nine months and in some samples the presence of 19-norandrosterone was confirmed by GC/C/IRMS analysis. The participants were genotyped for polymorphisms in PDE7B1 and UGT2B15 genes previously shown to influence the activation and inactivation of nandrolone decanoate. There were large inter-individual variations in the excretion rate of nandrolone and the metabolites, although not related to genetic variations in the UGT2B15 (rs1902023) and PDE7B1 (rs7774640) genes. After the administration, 19-norandrosterone was found at 2-8-fold higher concentrations than 19-noretiocholanolone. We showed that nandrolone doping can be identified 4 and 9 months after the injection of only one single dose in six and three individuals, respectively. We also noted that GC/C/IRMS confirms the presence of exogenous 19-norandrosterone in the urine samples, showing δ13 values around -32 ‰. This was true even in a sample that was not identified as an atypical finding after the GC-MS/MS analysis further showing the power of using GC/C/IRMS in routine anti-doping settings. PMID:26853157

    The objective was the cytoarchitecture evaluation of known steroid dependent target tissues after administering of testosterone, compared to action of its more active ester, nortestosterone (nandrolone decanoate) in castrated rat males in the aim of Hershberger bio test. Study was performed on 30 castrated male Wistar rats, aged between 35 and 39 days, in peripubertal period, divided into five groups. Androgen doses administration begun at the rats' age of 49 days. Animals were injected i.m., daily, for 10 consecutive days as follows: Aquatest (Balkan Pharmaceuticals Ltd., Moldova) testosterone aqueous solution: Testosterone I group (0.4 mg/animal); Testosterone II (0.8 mg/animal); (Deca-Durabolin, Balkan Pharmaceuticals); nandrolone decanoate oily solution: Nortestosterone I (1.5 mg/kg body weight); Nortestosterone II (7.5 mg/kg body weight) and Control (White sesame oil, Manicos, Romania, 0.1 mL/animal). Gonadectomy (GDX) induced modifications of target tissues wet weight accompanied by important modifications in cytoarchitecture. Changes following exogenous administration of testosterone and nortestosterone decanoate were found in: liver (granular dystrophy, mega-mitochondria, tubular intumescences), prostate (increasing of the structural elements), seminal vesicles (hyalinosis, thickening of cell walls and the hyaline presence), levator ani-bulbo-cavernosus muscle (muscle fibbers dilacerations), bulbourethral glands (muscular fibbers rarefaction by fluid accumulation) demonstrating the disruptor activity especially for overdosed nandrolone decanoate.

    Anabolic steroids used to improve muscular strength and performance in athletics. Its long-term consumption may induce cardiovascular adverse effects. We assessed the risk of ventricular arrhythmias in rats which subjected to chronic nandrolone plus high-intensity endurance exercise. Animals were grouped as; control (CTL), exercise (Ex): 8 weeks under exercise, vehicle group (Arach): received arachis oil, and Nan group: received nandrolone decanoate 5 mg/kg twice a week for 8 weeks, Arach+Ex group, and Nan+Ex. Finally, under anesthesia, arrhythmia was induced by infusion of 1.5 μg/0.1 mL/min of aconitine IV and ventricular arrhythmias were recorded for 15 min. Then, animals' hearts were excised and tissue samples were taken. Nandrolone plus exercise had no significant effect on blood pressure but decreased the heart rate (P<0.01) and increased the RR (P<0.01) and JT intervals (P<0.05) of electrocardiogram. Nandrolone+exercise significantly increased the ventricular fibrillation (VF) frequency and also decreased the VF latency (P<0.05 versus CTL group). Combination of exercise and nandrolone could not recover the decreasing effects of nandrolone on animals weight gain but, it enhanced the heart hypertrophy index (P<0.05). In addition, nandrolone increased the level of hydroxyproline (HYP) and malondialdehyde (MDA) but had not significant effect on glutathione peroxidase of heart. Exercise only prevented the effect of nandrolone on HYP. Nandrolone plus severe exercise increases the risk of VF that cannot be explained only by the changes in redox system. The intensification of cardiac hypertrophy and prolongation of JT interval may be a part of involved mechanisms.

    In a series of 3 experiments, adult male Long-Evans rats were castrated and treated with 1 of 3 different anabolic-androgenic steroid (AAS) compounds (17 alpha-methyltestosterone, methandrostenolone, or nandrolone decanoate) for 6 weeks. In each experiment, subjects received daily injections of a high, medium, or low dose of AAS or the oil vehicle. The AAS effects on body weight in gonadectomized male rats were modest, and no effects on locomotor activity were observed. The AAS compounds administered at doses comparable with human abuse levels were not equipotent in maintaining male sexual behavior patterns (nandrolone decanoate > methandrostenolone > 17 alpha-methyltestosterone). In addition, the behavioral actions of AAS compounds did not parallel stimulation of sexual accessory glands. The authors reported that this study is the first to quantify the dose-response characteristics of individual AAS compounds with regard to these behavioral and endocrine measures. PMID:8986348

    High doses of anabolic-androgenic steroids (AAS) are used by some athletes to increase muscle mass, that is often associated with male infertility. The aim of this study was to investigate the possible cause/s of male infertility using a rat model by analysing sperm quality, including its protamine content and DNA integrity, as well as pregnancy rate. Five groups of male Wistar rats were treated for 10 weeks as follows: nandrolone decanoate (10 mg kg(-1) per week) (ND); running exercise (50 min per day, 5 days a week) (EX); Combination of ND and exercise (ND-EX); nandrolone decanoate solvent (Sham); and control without any injection or exercise (CO). Deterioration in sperm quantity was observed in all test groups (P ≤ 0.01). The frequency of fertile rats was decreased in the ND-EX and ND groups (P ≤ 0.05). Chromomycin-A3 staining showed a protamine deficiency in the epididymal spermatozoa in the ND-EX rats (P ≤ 0.05). Chromatin analysis indicated an abnormal maturation of the sperm nuclei in all test groups compared with the controls (P ≤ 0.05). TUNEL analyses showed a highly significant increase in apoptosis in the EX, ND, and ND-EX groups (P ≤ 0.01). Our data show that a combination of exercise and high doses of nandrolone decanoate negatively influences the DNA integrity and protamine content resulting in lower sperm quality and reduced pregnancy rate.

    Background: Anabolic-androgenic steroids (AAS) are abused by athletes. Objectives: The present study was designed to evaluate chronic administration of high doses of nandrolone decanoate (ND) on the pituitary-gonadal axis and hematological parameters in normal male rats. Materials and Methods: Thirty Wistar-Albino male rats were divided assigned to control (C), placebo (P) and test (T) groups (n = 10). Group T received 15 mg/kg intramuscular (IM) ND for eight weeks. Group P received the same volume of peanut oil, but group C did not receive any agent during the trial period. At the end, animals were anesthetized, killed and blood samples collected from cervical vessels. Serum follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels were determined by sensitive rat gonadotropins kit, using ELISA methods. Serum testosterone and hematological parameters were measured by ordinary laboratory methods. Obtained data was analyzed using SPSS 17 by ANOVA and Tukey statistical tests. Results were expressed as Mean ± SD. Statistical difference considered significantly by P < 0.05. Results: Serum testosterone, LH, FSH, weight gain, food and water intake in group T were significantly decreased compared to other groups (P < 0.05). In addition erythrocyte, leucocytes, hemoglobin and hematocrit in group T were significantly increased compared to those of other groups (P < 0.05). Conclusions: Chronic administration of high doses of ND can alter serum FSH, LH and testosterone and hematological parameters in male rats. PMID:26495259

    Anabolic-androgenic steroids (AAS) are used in high doses by athletes to improve athletic ability, physical appearance, and muscle mass. Unfortunately, the abuse of these agents has significantly increased. It has been established that exercise and high doses of AAS may influence the hypothalamic-pituitary gonadal (H-P-G) axis, which can in turn affect the ultrastructure of the testes. However, the effect of the combination of exercise and high doses of AAS on the ultrastructure of the testes is not known. This study was undertaken in order to examine the combination effects of swimming exercise and supraphysiological doses of nandrolone decanoate on the ultrastructural changes in rat testes. Five groups of male Wistar strain albino rats were treated as follows for 8 weeks: solvent of nandrolone decanoate (peanut oil) as a vehicle (sham); nandrolone decanoate (ND) (10 mg/kg/week) - ND; exercise (1 h/day, 5 days a week) - exercise; ND (10 mg/kg/week) and exercise (1 h/day, 5 days a week) - ND-EX; and sedentary control without any injection or exercise - control. Ultrastructural changes in the rat testes were characterised by transmission electron microscopy. The number and size of Leydig cells were considerably decreased in the interstitial space in the experimental rats. The increased thickness and irregular wavy multilaminar appearance of basement membrane in the treated animals, especially in the ND-EX group, are associated with well developed myoid cells. Cytoplasm vacuolisation, vesicular-like crista of the mitochondria, numerous lipid droplets, and lysosome and phagolysosome in Sertoli cells were significantly observed in the experimental groups. Several apoptotic germ cells were considerably observed in the experimental rats (p ≤ 0.05). Exercise training seems to increase the extent of ultrastructural changes caused by supraphysiological doses of ND in rats, which in turn may affect fertility.

    Chronic exposure to the anabolic androgenic steroids (AAS) nandrolone decanoate (ND) in supra-physiological doses is associated with learning and memory impairments. Given the well-known beneficial effects of voluntary exercise on cognitive functions, we examined whether voluntary exercise would improve the cognitive deficits induced by chronic administration of ND. We also investigated the effects of ND and voluntary exercise on hippocampal BDNF levels. The rats were randomly distributed into 4 experimental groups: the vehicle-sedentary group, the ND-sedentary group, the vehicle-exercise group, and the ND-exercise group. The vehicle-exercise and the ND-exercise groups were allowed to freely exercise in a running wheel for 15 days. The vehicle-sedentary and the ND-sedentary groups were kept sedentary for the same period. Vehicle or ND injections were started 14 days prior to the voluntary exercise and continued throughout the 15 days of voluntary exercise. After the 15-day period, the rats were trained and tested on a water maze spatial task using four trials per day for 5 consecutive days followed by a probe trial two days later. Exercise significantly improved performance during both the training and retention of the water maze task, and enhanced hippocampal BDNF. ND impaired spatial learning and memory, and this effect was not rescued by exercise. ND also potentiated the exercise-induced increase in hippocampal BDNF levels. These results seem to indicate that voluntary exercise is unable to improve the disruption of cognitive functions by chronic ND. Moreover, increased levels of BDNF may play a role in ND-induced impairments in learning and memory. The harmful effects of ND and other AAS on learning and memory should be taken into account when athletes decide to use AAS for performance or body image improvement.

    Background: Most studies on anabolic-androgenic steroids abuse have been done in adult rats, but few data are available to immature. Objective: This study was conducted to assay the effect of Nandrolone Decanoate (ND) on the testis and testosterone concentration in male immature rats compare with mature ones in short and long time. Materials and Methods: 40 mature rats were divided into 4 groups: group A (short term) and group B (long-term) received 10 mg/kg/day ND interaperitoneally for 35 and 70 days, respectively. Group C (control) without any treatment, and group D (vehicle) received dimethyl sulfoxide (DMSO) solution in two periods 35 and 70 days. 40 immature rats were divided into 4 groups same as mature ones. After surgery body weight, testis size, histomorphometry of testis, and serum testosterone level were evaluated. Results: Our results showed that ND decreased the number of Leydig cells in group B (39.9 ±. 919), group A (43.4 ±. 120), and long term (40.6 ±. 299) immature rats, which could result in a reduction of testosterone concentration significantly in all experimental groups except short term mature group. Number of sertoli cells, testis size, and diameter of seminiferous tubules decreased in the long-term immature group. Eventually, the number of sperm was decreased in mature and immature groups, but a severe depletion of sperm was occurred in both mature and immature in long time in comparison to the control group (p< 0.05). Conclusion: This time course study showed that supraphysiological dose of ND may negatively affect the number of Leydig cells, sperm cell, and testosterone concentration of immature rats in the same matter of mature rats. However, the number of sertoli cell, testis size, and seminferous diameter were decreased only in the long immature rats. PMID:27141538

    Behavioral perturbations associated with nandrolone decanoate abuse by athletes and adolescents may be attributed to oxidative stress and inflammation. However, the underlying mechanisms are not yet fully explored. On the other hand, the natural antioxidant lipoic acid can pass the blood brain barrier and enhance Nrf2/HO-1 (nuclear factor erythroid-2 related factor 2/heme oxygenase-1) pathway. In addition, the phosphodiesterase-IV inhibitor xanthine derivative pentoxifylline has a remarkable inhibitory effect on tumor necrosis factor-alpha (TNF-α). Therefore, this study aimed at investigation of the possible protective effects of lipoic acid and/or pentoxifylline against nandrolone-induced neurobehavioral alterations in rats. Accordingly, male albino rats were randomly distributed into seven groups and treated with either vehicle, nandrolone (15mg/kg, every third day, s.c.), lipoic acid (100mg/kg/day, p.o.), pentoxifylline (200mg/kg/day, i.p.), or nandrolone with lipoic acid and/or pentoxifylline. Rats were challenged in the open field, rewarded T-maze, Morris water maze, and resident-intruder aggression behavioral tests. The present findings showed that nandrolone induced hyperlocomotion, anxiety, memory impairment, and aggression in rats. These behavioral abnormalities were accompanied by several biochemical changes, including altered levels of brain monoamines, GABA, and acetylcholine, enhanced levels of malondialdehyde and TNF-α, elevated activity of acetylcholinesterase, and up-regulated expression of TNF-α receptor-1 (TNFR1). In addition, inhibited catalase activity, down-regulated Nrf2/HO-1 pathway, and suppressed acetylcholine receptor expression were observed. Lipoic acid and pentoxifylline combination significantly mitigated all the previously mentioned deleterious effects mainly via up-regulation of Nrf2/HO-1 pathway, inhibition of TNF-α and down-regulation of TNFR1 expression.

    Nandrolone decanoate administration and strenuous exercise increase the extent of renal damage in response to renal toxic injury. We studied the role played by oxidative stress in the apoptotic response caused by nandrolone decanoate in the kidneys of strength-trained male CD1 mice. To measure cytosolic enzyme activity, glutathione peroxidase (GPx), glutathione reductase (GR) and malondialdehyde (MDA) were determined after nandrolone treatment. An immunohistochemical study and Western blot analysis were performed to evaluate cell apoptosis and to measure the effects of renal expression of inflammatory mediators (IL-1β, TNF-α) on the induction of apoptosis (HSP90, TUNEL). Dose-related oxidative damage in the kidneys of treated mice is shown by an increase in MDA levels and by a reduction of antioxidant enzyme GR and GPx activities, resulting in the kidney's reduced radical scavenging ability. Renal specimens of the treated group showed relevant glomeruli alterations and increased immunostaining and protein expressions, which manifested significant focal segmental glomerulosclerosis. The induction of proinflammatory cytokine expression levels was confirmed by Western blot analysis. Long-term administration of nandrolone promotes oxidative injury in the mouse kidneys. TNF-α mediated injury due to nandrolone in renal cells appears to play a role in the activation of both the intrinsic and extrinsic apoptosis pathways. - Highlights: • We analyze abuse of nandrolone decanoate in strength-trained male CD1 mice. • Nandrolone decanoate administration increases oxidative stress. • Increased cytokine expressions were observed. • Renal apoptosis was described. • Long-term administration of nandrolone promotes oxidative injury in mice kidney.

    Data in animal models and surveys in humans have shown psychiatric complications of long-term anabolic androgenic steroids abuse. However, neurobiochemical mechanisms behind observed behavioral changes are poorly understood. The aim of the present study was to investigate the effects of nandrolone decanoate on emotional behavior and neurochemical brain alterations in gonadally intact male rats. Behavioral reactivity to elevated plus maze and social interaction test was used to assess anxiety-related symptoms, while sucrose preference test was used to evaluate anhedonia. Dopaminergic, serotonergic and noradrenergic transmissions were also evaluated in selected brain areas. Chronic administration of nandrolone, at 5 mg kg(-1) injected for 4 weeks, induced loss of sweet taste preference, as sign of anhedonia and dysfunction of reward pathway. Behavioral outcomes were accompanied by reduction of dopamine, serotonin and noradrenaline contents in nucleus accumbens. Neither alterations in time spent in open arms nor in social interaction test were found, suggesting that nandrolone did not induce an anxiogenic profile. No differences were revealed between experimental groups in the amygdala in terms of neurotransmitters measured. Our data suggest that nandrolone-treated rats have a depressive, but not anxiogenic-like, profile, accompanied by brain region-dependent changes in dopaminergic, serotonergic and noradrenergic neurotransmission. As anabolic androgenic steroid dependence is plausibly the major form of worldwide substance dependence that remains largely unexplored, it should be underlined that our data could contribute to a better understanding of altered reward induced by nandrolone treatment and to develop appropriate treatment.

    Associated with acts of violence and polydrug use, abuse of anabolic androgenic steroids (AAS) is an increasing problem in society. The aim of the present study was to elucidate whether sub-chronic treatment with the AAS nandrolone decanoate affects dopamine release and dopamine metabolism in the rat nucleus accumbens shell, before and after an amphetamine challenge. Male Sprague-Dawley rats received daily i.m. injections of nandrolone decanoate (15 mg/kg) or vehicle for 14 days. On day 15, the animals were anaesthetized and a microdialysis probe was implanted into the nucleus accumbens shell. Extracellular fluid was collected 1h before and 3h after a single amphetamine injection (5 mg/kg). The samples were then analyzed regarding the content of dopamine, and its metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA), using HPLC with electrochemical detection. Two weeks of nandrolone decanoate administration caused a significant decrease of the basal DOPAC and HVA levels, which remained low during the first hour following the amphetamine challenge. Dopamine levels did not differ significantly between groups, neither after the nandrolone pre-treatment nor the amphetamine challenge. In conclusion, these novel findings indicate that AAS alter the metabolism of dopamine in a brain region involved in the development of drug dependence.

    Background: Until now, no experimental study has directly assessed the arrhythmogenesis of chronic consumption of anabolic androgenic steroids along with moderate-intensity endurance exercise. Objectives: We evaluated the influence of integration of anabolic androgenic steroids along with moderate-intensity endurance exercise on susceptibility to lethal ventricular arrhythmias in rat. Materials and Methods: The animal groups were as follows: control group (CTL); exercise group (EX) which were under 6 weeks of treadmill exercise; nandrolone group (Nan) which received 5 mg/kg of nandrolone decanoate twice a week; vehicle group (Arach) which received Arachis oil (solvent of nandrolone); trained vehicle group (Arach + Ex); and trained nandrolone group (Nan + Ex). One day after ending of the intervention period, arrhythmia was inducted by intravenous infusion of aconitine and ventricular arrhythmias were recorded. Then malondialdehyde (MDA) and glutathione peroxidase (GPX) of heart tissue were measured. Results: Nandrolone, exercise, and their combination were associated with heart hypertrophy. Exercise could prevent the incremental effect of nandrolone on MDA/GPX ratio. Chronic administration of nandrolone with moderate-intensity endurance exercise had no significant effect on blood pressure, heart rate, and basal electrocardiographic parameters. Combination of nandrolone and exercise significantly increased the incidence of ventricular fibrillation (VF) and reduced the VF latency (P < 0.05). Conclusions: The findings suggest that chronic coadministration of nandrolone with moderate-intensity endurance exercise facilitates the VF occurrence in rat. Complementary studies are needed to elucidate the involved mechanisms of this abnormality. PMID:26396972

    Data in animal models and surveys in humans have revealed psychiatric complications of long-term anabolic androgenic steroid abuse. However, the neurobiochemical mechanisms behind the observed behavioral changes are poorly understood. The aim of the present study was to investigate the effects of nandrolone decanoate on emotional behavior and neurochemical brain alterations in gonadally intact male rats. The behavioral reactivity to the elevated plus maze and the social interaction test was used to assess anxiety-related symptoms, and the sucrose preference test was used to evaluate anhedonia. Dopaminergic, serotonergic and noradrenergic transmissions were also evaluated in selected brain areas. The chronic administration of nandrolone, at 5 mg kg(-1) injected daily for 4 weeks, induced the loss of sweet taste preference, a sign of anhedonia and dysfunction of the reward pathway. The behavioral outcomes were accompanied by reductions in the dopamine, serotonin and noradrenaline contents in the nucleus accumbens. Alterations in the time spent in the open arms and in the social interaction test were not found, suggesting that nandrolone did not induce an anxiogenic profile. No differences were revealed between the experimental groups in the amygdala in terms of the neurotransmitters measured. Our data suggest that nandrolone-treated rats have a depressive, but not anxiogenic-like, profile, accompanied by brain region-dependent changes in dopaminergic, serotonergic and noradrenergic neurotransmission. As anabolic androgenic steroid dependence is plausibly the major form of worldwide substance dependence that remains largely unexplored, it should be highlighted that our data could contribute to a better understanding of the altered rewards induced by nandrolone treatment and to the development of appropriate treatments.

    The clinical effect of clopenthixol decanoate has been assessed in a 5-month controlled including 21 hospitalized chronic schizophrenic patients. The ratings were done with BPRS, NOSIE 30, the two psychological tests of WAIS and Grübaum, and the rating scale of Simpson & Angus to assess extrapyramidal side effects. Clopenthixol decanoate was found an effective and long-acting antipsychotic compound with few autonomic and neurological side effects. Compared with previous maintenance treatment it also showed a positive influence on depression and facilitation of the social adaptation of the patients.

    There is growing interest in the use of the ketogenic diet (KD) to treat inherited metabolic diseases including mitochondrial disorders. However, neither the mechanism whereby the diet may be working, nor if it could benefit all patients with mitochondrial disease, is known. This study focusses on decanoic acid (C10), a component of the medium chain triglyceride KD, and a ligand for the nuclear receptor PPAR-γ known to be involved in mitochondrial biogenesis. The effects of C10 were investigated in primary fibroblasts from a cohort of patients with Leigh syndrome (LS) caused by nuclear-encoded defects of respiratory chain complex I, using mitochondrial respiratory chain enzyme assays, gene expression microarray, qPCR and flow cytometry. Treatment with C10 increased citrate synthase activity, a marker of cellular mitochondrial content, in 50 % of fibroblasts obtained from individuals diagnosed with LS in a PPAR-γ-mediated manner. Gene expression analysis and qPCR studies suggested that treating cells with C10 supports fatty acid metabolism, through increasing ACADVL and CPT1 expression, whilst downregulating genes involved in glucose metabolism (PDK3, PDK4). PCK2, involved in blocking glucose metabolism, was upregulated, as was CAT, encoding catalase. Moreover, treatment with C10 also decreased oxidative stress in complex I deficient (rotenone treated) cells. However, since not all cells from subjects with LS appeared to respond to C10, prior cellular testing in vitro could be employed as a means for selecting individuals for subsequent clinical studies involving C10 preparations.

    The medium chain triglyceride ketogenic diet is an established treatment for drug-resistant epilepsy that increases plasma levels of decanoic acid and ketones. Recently, decanoic acid has been shown to provide seizure control in vivo, yet its mechanism of action remains unclear. Here we show that decanoic acid, but not the ketones β-hydroxybutryate or acetone, shows antiseizure activity in two acute ex vivo rat hippocampal slice models of epileptiform activity. To search for a mechanism of decanoic acid, we show it has a strong inhibitory effect on excitatory, but not inhibitory, neurotransmission in hippocampal slices. Using heterologous expression of excitatory ionotropic glutamate receptor AMPA subunits in Xenopus oocytes, we show that this effect is through direct AMPA receptor inhibition, a target shared by a recently introduced epilepsy treatment perampanel. Decanoic acid acts as a non-competitive antagonist at therapeutically relevant concentrations, in a voltage- and subunit-dependent manner, and this is sufficient to explain its antiseizure effects. This inhibitory effect is likely to be caused by binding to sites on the M3 helix of the AMPA-GluA2 transmembrane domain; independent from the binding site of perampanel. Together our results indicate that the direct inhibition of excitatory neurotransmission by decanoic acid in the brain contributes to the anti-convulsant effect of the medium chain triglyceride ketogenic diet.

    Characterized by low serum testosterone levels and diverse symptoms, male hypogonadism is a common condition. Current medical treatment focuses on testosterone supplementation using multiple modalities such as injections, gels and pellets. Interestingly, while testosterone is considered an anabolic androgenic steroid, it has not been saddled with the social stigma that other, similar medications have. The goal of this review is to highlight an anabolic steroid, 19-nortestosterone (i.e., nandrolone, deca-durabolin) and illustrate prospective therapeutic applications for male health. Containing a chemical structure similar to testosterone, nandrolone has a higher myotrophic: androgenic ratio resulting in improved effects on muscle mass. Animal models have suggested application in the improvement of joint healing following rotator cuff repair. Minimal literature exists regarding the use of nandrolone and, as such, further human studies are required. PMID:27141449

    Androgenic-anabolic steroids (AAS) have been associated with an increased incidence of tendon rupture. The aim of this study was to compare the biomechanical properties of the rat calcaneal tendon (CT), superficial flexor tendon (SFT), and deep flexor tendon (DFT), and to determine the effect of jump training in association with AAS. Animals were separated into four groups: sedentary, trained, AAS-treated sedentary rats (AAS), and AAS-treated and trained animals. Mechanical testing showed that the CT differed from the DFT and SFT, which showed similar mechanical properties. Jump caused the CT to exhibit an extended toe region, an increased resistance to tensional load, and a decreased elastic modulus, characteristics of an elastic tendon capable of storing energy. AAS caused the tendons to be less compliant, and the effects were reinforced by simultaneous training. The DFT was the most affected by training, AAS, and the interaction of both, likely because of its involvement in the toe-off step of jumping, which we suggest is related to the rapid transmission of force as opposed to energy storage. In conclusion, tendons are differently adapted to exercise, but responded equally to AAS, showing reduced flexibility, which is suggested to increase the risk of tendon rupture in AAS consumers.

    Background: Anabolic androgenic steroids (AAS) is being used in medical treatments, but AAS also was identified to have the risks of adverse effects towards patients and consumers health. Objective: Present study was conducted to observe the effects of testosterone, nandrolone, and stanozolol (forms of AAS) intake during onset of puberty on the rat testicular histology. Materials and Methods: Juvenile male Sprague-Dawley (SD) rats (n=42) were divided into seven groups and were injected subcutaneously with medium dose of polyethylene glycol-200 (PEG-200) (control), testosterone, nandrolone, and stanozolol for six weeks (PND 41-87). The animals were weighed daily and sacrificed on PND 88. Testes were removed, weighed, and prepared for histological assessment and finally specimens were observed under microscope. Results: The results showed an insignificant increase in mean daily body weight with highest and lowest body weight gained was of 177.6±1.69 gr and 140.0±12.26 gr respectively. There was significant decrease in the testes absolute weight (p≤0.01) in all experimental groups except in the nandrolone 2.5 mg/kg/week treated group. Testicular histology of rats treated with AAS also showed slight changes in the uniformity of arrangements of seminiferous tubules. Conclusion: Data from present study suggests that AAS have been initiating the adverse effects on testicular normal functions in rats during onset of puberty. PMID:24639803

    High doses of anabolic androgenic steroids (AAS) impair the cardioprotective effects of exercise against ischemia/reperfusion (I/R) insult, possibly through cellular redox imbalance. Here, the effect of nandrolone decanoate (DECA) treatment on heart redox metabolism was investigated during I/R in sedentary and exercised rats. DECA treatment significantly reduced superoxide dismutase and glutathione reductase activities in exercised rats after heart reperfusion. Catalase and glutathione peroxidase activities were not affected by DECA in both sedentary and trained rats, regardless the I/R period. DECA also induced myocardial oxidative stress, as evidenced by the reduced levels of total reduced thiols after heart reperfusion in exercised rats treated with the anabolic steroid. These results indicate that cardiotoxic effects of supraphysiological doses of AAS involve reduced heart antioxidant capacity.

    Anabolic androgenic steroids (AAS) are among the drugs most used by athletes for improving physical performance, as well as for aesthetic purposes. A number of papers have showed the side effects of AAS in different organs and tissues. For example, AAS are known to suppress gonadotropin-releasing hormone, luteinizing hormone, and follicle-stimulating hormone. This study investigates the effects of nandrolone on testosterone biosynthesis in Leydig cells using various methods, including mass spectrometry, western blotting, confocal microscopy and quantitative real-time PCR. The results obtained show that testosterone levels increase at a 3.9 μM concentration of nandrolone and return to the basal level a 15.6 μM dose of nandrolone. Nandrolone-induced testosterone increment was associated with upregulation of the steroidogenic acute regulatory protein (StAR) and downregulation of 17a-hydroxylase/17, 20 lyase (CYP17A1). Instead, a 15.6 µM dose of nandrolone induced a down-regulation of CYP17A1. Further in vivo studies based on these data are needed to better understand the relationship between disturbed testosterone homeostasis and reproductive system impairment in male subjects.

    Biodiesel is typically a mixture of long chain fatty acid methyl esters for use in compression ignition engines. Improving biofuel engine performance requires understanding its fundamental combustion properties and the pathways of combustion. This research study presents new combustion data for methyl decanoate in an opposed-flow diffusion flame. An improved detailed chemical kinetic model for methyl decanoate combustion is developed, which serves as the basis for deriving a skeletal mechanism via the direct relation graph method. The novel skeletal mechanism consists of 648 species and 2998 reactions. This mechanism well predicts the methyl decanoate opposed-flow diffusion flame data. The results from the flame simulations indicate that methyl decanoate is consumed via abstraction of hydrogen atoms to produce fuel radicals, which lead to the production of alkenes. The ester moiety in methyl decanoate leads to the formation of low molecular weight oxygenated compounds such as carbon monoxide, formaldehyde, and ketene.

    Highlights: {yields} Nerve transection increased Notch signaling in paralyzed muscle. {yields} Nandrolone prevented denervation-induced Notch signaling. {yields} Nandrolone induced the expression of an inhibitor of the Notch signaling, Numb. {yields} Reduction of denervation-induced Notch signaling by nandrolone is likely through upregulation of Numb. -- Abstract: Nandrolone, an anabolic steroid, slows denervation-atrophy in rat muscle. The molecular mechanisms responsible for this effect are not well understood. Androgens and anabolic steroids activate Notch signaling in animal models of aging and thereby mitigate sarcopenia. To explore the molecular mechanisms by which nandrolone prevents denervation-atrophy, we investigated the effects of nandrolone on Notch signaling in denervated rat gastrocnemius muscle. Denervation significantly increased Notch activity reflected by elevated levels of nuclear Notch intracellular domain (NICD) and expression of Hey1 (a Notch target gene). Activation was greatest at 7 and 35 days after denervation but remained present at 56 days after denervation. Activation of Notch in denervated muscle was prevented by nandrolone associated with upregulated expression of Numb mRNA and protein. These data demonstrate that denervation activates Notch signaling, and that nandrolone abrogates this response associated with increased expression of Numb, suggesting a potential mechanism by which nandrolone reduces denervation-atrophy.

Both agents exhibit favorable myotrophic/androgenic ratios and have been investigated for effectiveness in numerous disease states. We also provide a brief synopsis of selective androgen receptor modulators (SARMs) and postulate how these orally active, non-aromatizing, tissue-selective agents might be used in contemporary andrology. Currently, the applications of testosterone alternatives in hypogonadism are limited. However, it is tempting to speculate that these agents may one day become accepted as alternatives, or adjuncts, to the treatment of male hypogonadism.

    Perfluoro-n-decanoic acid (PFDA) is a member of a family of perfluorinated carboxylic acids that have found widespread commercial applications as lubricants, surfactants, wetting agents and corrosion inhibitors. The effects of thyroxine (T{sub 4}) supplementation on perfluoro-n-decanoic acid- (PFDA) induced decreases in food consumption, body weight, and body temperature were examined. A dose-response study was carried out with 50-, 100-, 200-, or 250-{mu}g/kg ip doses of T{sub 4} for 7 d prior to PFDA administration, and daily dosing with T{sub 4} was continued for an additional 30 d. From this study a T{sub 4} dose of 200 {mu}g/kg was chosen, and subsequent experiments were conducted with this dose. Supplementation with T{sub 4} at 200 {mu}g/kg daily alleviated the hypophagia but not the severe weight loss and hypothermia produced by PFDA treatment. Their results suggest that some component of the thyroid axis plays a role in feeding behavior. In addition, the PFDA-induced wasting syndrome and hypothermia appear to be unrelated to changes in serum thyroid hormones. The unexpected observation that severe weight loss occurred in the presence of essentially normal food intake suggests that PFDA alters basic cellular metabolic processes.

    Objectives: Antipsychotic polypharmacy (APP) is common clinical practice. Theoretically, APP runs the risk of additional side effects, drug interactions, adherence and cost. A limited evidence base is emerging to support the effectiveness of APP in clinical practice. Our companion paper highlighted the extent of APP alongside commonly prescribed long-acting antipsychotic injections (LAIs). We aimed to examine the effects of APP on discontinuation rates and Clinical Global Impression (CGI) outcomes in patients commenced on risperidone long-acting injection (RLAI) and zuclopenthixol decanoate. Method: LAI-naïve patients commenced on RLAI (n = 102) and zuclopenthixol decanoate(n = 105) were identified using our electronic patient record (running from 2002) within NHS Lanarkshire, Scotland, UK. This was a retrospective, electronic case note review with an 18-month follow up. Patient groups were divided into those receiving the LAI as the sole antipsychotic and those who were receiving additional oral antipsychotic polypharmacy (APP) for at least 50% of the duration of the treatment with their LAI. Kaplan–Meier statistics were calculated for discontinuation rates. CGI severity and improvement scores were retrospectively assigned by the investigating team. Results: Antipsychotic polypharmacy occurred with RLAI (37%) and zuclopenthixol decanoate (46%) and was associated with lower discontinuation rates (statistical significant with zuclopenthixol for any cause and adverse effects discontinuation). APP had no adverse outcomes on hospital admissions or CGI ratings. Patients on APP did not have more severe, chronic or treatment resistant illnesses. Conclusions: For RLAI and zuclopenthixol decanoate, APP had some favourable outcomes when examining discontinuation rates for any cause, and adverse effects. This was unexpected as we had considered APP would signal illness chronicity and severity and be associated with increased adverse effects resulting in early

    A long-term study was performed on the effects of fluphenazine decanoate and the results were compared with those of fluphenazine-2HCl and fluphenazine enanthate. These agents given orally were equipotent in inhibiting the motility of mice. With subcutaneous administration, decanoate and enanthate showed a clearly prolonged action, whereas fluphenazine-2HCl was effective for only 3 days. Decanoate and enanthate did not produce marked hypothermia in rats. Like enanthate, decanoate inhibited, for a long duration, apomorphine-induced stereotyped behavior and methamphetamine group toxicity in mice, as well as induced catalepsy in rats. It was found that fluphenazine-2HCl markedly inhibited certain agonists-induced contraction of isolated preparations while enanthate and decanoate inhibited these contractions almost equally. In rats, enanthate induced a persistent hypotension and marked changes in ECG while decanoate showed a transient hypotension and slight changes in ECG. In the study of rat brain catecholamine turnover, these three drugs significantly increased dopamine turnover, and decanoate and enanthate were found to have prolonged effects. No significant change in noradrenaline turnover was observed. These results indicate that fluphenazine decanoate has the same spectrum of activity as enanthate except for its slower onset, weaker potency and longer duration of action. A prolonged tranquilizing effect was most evident.

    In order to investigate the possible antagonistic effect between glucocorticoids and androgens on muscle protein turnover, the authors have measured the fractional rates of gastrocnemius muscle protein synthesis (k/sub s/) and degradation (k/sub d/) by the constant-intravenous-infusion method using L-//sup 14/C/-tyrosine in rats receiving via s.c. per 100 g b.wt. 10 mg of CC, or 2 mg of ND or CC+ND at the indicated doses, and fed either an 18% or 5% protein diets over a period of 5 days. As an additional index of protein synthesis, RNA activity (g of synthesized protein/day/g RNA) was determined as well. Results showed that as compared to vehicle-injected animals fed the adequate diet, CC-treated rats exhibited a reduction of muscle k/sub d/, while ND-treated rats had an outstanding increase of muscle k/sub s/. However, rats receiving CC+ND showed k/sub s/ and k/sub d/ values similar to those displayed by control animals. Nevertheless, when the steroids were injected to rats fed the low-protein diet, CC has a catabolic effect on muscle protein but by reducing k/sub s/, while the anabolic action of ND is still displayed but by a significant reduction of muscle k/sub d/. CC+ND given to these protein-deficient rats caused an increase in muscle k/sub s/ and a reduction in k/sub d/. These results might indicate that, at least in part, ND antagonizes the catabolic action of high doses of CC on muscle protein metabolism.

    Anabolic-androgenic steroid (AAS) abuse is associated with multiple neurobehavioral disturbances. The sites of action and the neurobiological sequels of AAS abuse are unclear at present. We investigated whether two different AASs, nandrolone and methandrostenolone, could affect neuronal survival in culture. The endogenous androgenic steroid testosterone was used for comparison. Both testosterone and nandrolone were neurotoxic at micromolar concentrations, and their effects were prevented by blockade of androgen receptors (ARs) with flutamide. Neuronal toxicity developed only over a 48-hr exposure to the steroids. The cell-impermeable analogues testosterone-BSA and nandrolone-BSA, which preferentially target membrane-associated ARs, were also neurotoxic in a time-dependent and flutamide-sensitive manner. Testosterone-BSA and nandrolone-BSA were more potent than their parent compounds, suggesting that membrane-associated ARs were the relevant sites for the neurotoxic actions of the steroids. Unlike testosterone and nandrolone, toxicity by methandrostenolone and methandrostenolone-BSA was insensitive to flutamide, but it was prevented by the glucocorticoid receptor (GR) antagonist RU-486. Methandrostenolone-BSA was more potent than the parent compound, suggesting that its toxicity relied on the preferential activation of putative membrane-associated GRs. Consistently with the evidence that membrane-associated GRs can mediate rapid effects, a brief challenge with methandrostenolone-BSA was able to promote neuronal toxicity. Activation of putative membrane steroid receptors by nontoxic (nanomolar) concentrations of either nandrolone-BSA or methandrostenolone-BSA became sufficient to increase neuronal susceptibility to the apoptotic stimulus provided by β-amyloid (the main culprit of AD). We speculate that AAS abuse might facilitate the onset or progression of neurodegenerative diseases not usually linked to drug abuse. PMID:21290409

  1. Transcriptional analysis of the effect of exogenous decanoic acid stress on Streptomyces roseosporus

    PubMed Central

    2013-01-01

    Backgroud Daptomycin is an important antibiotic against infections caused by drug-resistant pathogens. Its production critically depends on the addition of decanoic acid during fermentation. Unfortunately, decanoic acid (>2.5 mM) is toxic to daptomycin producer, Streptomyces roseosporus. Results To understand the mechanism underlying decanoic tolerance or toxicity, the responses of S. roseosporus was determined by a combination of phospholipid fatty acid analysis, reactive oxygen species (ROS) measurement and RNA sequencing. Assays using fluorescent dyes indicated a sharp increase in reactive oxygen species during decanoic acid stress; fatty acid analysis revealed a marked increase in the composition of branched-chain fatty acids by approximately 10%, with a corresponding decrease in straight-chain fatty acids; functional analysis indicated decanoic acid stress has components common to other stress response, including perturbation of respiratory functions (nuo and cyd operons), oxidative stress, and heat shock. Interestingly, our transcriptomic analysis revealed that genes coding for components of proteasome and related to treholase synthesis were up-regulated in the decanoic acid –treated cells. Conclusion These findings represent an important first step in understanding mechanism of decanoic acid toxicity and provide a basis for engineering microbial tolerance. PMID:23432849

    Neuroleptic Malignant Syndrome (NMS) is unusual but could be a lethal reaction associated with neuroleptic drugs. It occurs in almost 0.07-2.2% of patients under treatment with neuroleptics. There are some medical treatments that may also be helpful for its treatment, including dopamine agonists, muscle relaxants, and electroconvulsive therapy (ECT). We present this case to alert the clinicians to the potential for inducing afebrile NMS. Our case is a 41-year-old man with a history of schizophrenia showing signs and symptoms in accordance with NMS, 2 weeks after receiving one dose of 12.5 mg fluphenazine decanoate, abruptly following the 3rdsession of ECT. The patient presented with decreased level of consciousness, muscular rigidity, waxy flexibility, mutism, generalized tremor, sever diaphoresis and tachycardia which progressed during the previous 24 h. Laboratory data indicated primarily leukocytosis, an increasing level of creatinine phosphokinase and hypokalemia during the next 72h. In patients receiving antipsychotics, any feature of NMS should carefully be evaluated whether it is usual or unusual particularly in patients receiving long acting neuroleptics. PMID:22952496

    Adolescents and adults engage in anabolic-androgenic steroid (AAS) misuse seeking their anabolic effects, even though later on, many could develop neuropsychological dependence. Previously, we have shown that nandrolone induces conditioned place preference (CPP) in adult male mice. However, whether nandrolone induces CPP during adolescence remains unknown. In this study, the CPP test was used to determine the rewarding properties of nandrolone (7.5 mg/kg) in adolescent mice. In addition, since D1 dopamine receptors (D1DR) are critical for reward-related processes, the effect of nandrolone on the expression of D1DR in the nucleus accumbens (NAc) was investigated by Western blot analysis. Similar to our previous results, nandrolone induced CPP in adults. However, in adolescents, nandrolone failed to produce place preference. At the molecular level, nandrolone decreased D1DR expression in the NAc only in adult mice. Our data suggest that nandrolone may not be rewarding in adolescents at least during short-term use. The lack of nandrolone rewarding effects in adolescents may be due, in part to differences in D1DR expression during development. PMID:25612844

    Fluphenazine, a potent antipsychotic used to treat schizophrenia in humans, is used in racehorses as a performance-enhancing drug, and for that reason it has been banned by the Association of Racing Commissioners International. A liquid chromatography-tandem mass spectrometry method for detecting and quantitating fluphenazine in equine serum was developed and validated. The method was then employed to quantitate fluphenazine in serum samples collected from three study horses after intramuscular injection of fluphenazine decanoate. Stability testing showed that fluphenazine is stable in unextracted and processed samples as well as samples that have been subjected to up to three freeze-thaw cycles. The limit of detection and lower limit of quantitation of fluphenazine were determined to be 0.05 and 0.1 ng/mL, respectively. Precision was evaluated based on one-way analysis of variance of replicate quality control samples and was determined to be 27.2% at the 0.2 ng/mL level and 18.1% at the 2 ng/mL level. Bias was determined to be 0.55% at the 0.2 ng/mL level and 3.66% at the 2 ng/mL level. In two of three horses, fluphenazine was detected in serum up to 14 days post-administration. The highest detected concentration of fluphenazine in serum was 1.4 ng/mL.

    Methyl decanoate is a large methyl ester that can be used as a surrogate for biodiesel. In this experimental and computational study, the combustion of methyl decanoate is investigated in nonpremixed, nonuniform flows. Experiments are performed employing the counterflow configuration with a fuel stream made up of vaporized methyl decanoate and nitrogen, and an oxidizer stream of air. The mass fraction of fuel in the fuel stream is measured as a function of the strain rate at extinction, and critical conditions of ignition are measured in terms of the temperature of the oxidizer stream as a function of the strain rate. It is not possible to use a fully detailed mechanism for methyl decanoate to simulate the counterflow flames because the number of species and reactions is too large to employ with current flame codes and computer resources. Therefore a skeletal mechanism was deduced from a detailed mechanism of 8555 elementary reactions and 3036 species using 'directed relation graph' method. This skeletal mechanism has only 713 elementary reactions and 125 species. Critical conditions of ignition were calculated using this skeletal mechanism and are found to agree well with experimental data. The predicted strain rate at extinction is found to be lower than the measurements. In general, the methyl decanoate mechanism provides a realistic kinetic tool for simulation of biodiesel fuels.

    A multitarget antibody immunoaffinity column was proposed for the purification and enrichment of nandrolone, testosterone, and methyltestosterone from urine. Nandrolone-3-site substituted antigen was designed and synthesized and the polyclonal antibody was prepared with immunizing rabbits. The stationary phase of the immunoaffinity column was synthesized by covalently bonding the antibodies specific to nandrolone, testosterone, and methyltestosterone onto CNBr-actived Sepharose 4B. The analytes of interest were extracted with a methanol/water mixture in one step. The immunoaffinity column showed high affinity and high selectivity to a class of structurally related compounds. The elution was then transferred to a micellar electrokinetic CE system with a running buffer of sodium borate and sodium cholate for separation and determination. Recoveries of the three steroids from complex matrix were 88-94% with RSD values less than 5.2%. Optimization of the immunoaffinity column purification was achieved and the feasibility of the technique for the analysis of steroid hormone was discussed. The results indicated that the combination of multi-immunoaffinity column and CE was an effective technique, which was rapid, simple, and sensitive for the assay of steroids.

    The illicit use of supraphysiological doses of androgenic steroids (AAS) has been suggested as a cause of arrhythmia in athletes. The objectives of the present study were to investigate the time-course and the cellular, ionic and molecular processes underlying ventricular repolarization in rats chronically treated with AAS. Male Wistar rats were treated weekly for 8 weeks with 10mg/kg of nandrolone decanoate (DECA n=21) or vehicle (control n=20). ECG was recorded weekly. Action potential (AP) and transient outward potassium current (I(to)) were recorded in rat hearts. Expression of KChIP2, Kv1.4, Kv4.2, and Kv4.3 was assessed by real-time PCR. Hematoxylin/eosin and Picrosirius red staining were used for histological analysis. QTc was greater in the DECA group. After DECA treatment the left, but not right, ventricle showed a longer AP duration than did the control. I(to) current densities were 47.5% lower in the left but not in the right ventricle after DECA. In the right ventricle the I(to) inactivation time-course was slower than in the control group. After DECA the left ventricle showed lower KChIP2 ( approximately 26%), Kv1.4 ( approximately 23%) and 4.3 ( approximately 70%) expression while the Kv 4.2 increased in 4 ( approximately 250%) and diminished in 3 ( approximately 30%) animals of this group. In the right ventricle the expression of I(to) subunits was similar between the treatment and control groups. DECA-treated hearts had 25% fewer nuclei and greater nuclei diameters in both ventricles. Our results strongly suggest that supraphysiological doses of AAS induce morphological remodeling in both ventricles. However, the electrical remodeling was mainly observed in the left ventricle.

    Foragers of many species of stingless bees guide their nestmates to food sources by means of scent trails deposited on solid substrates between the food and the nest. The corresponding trail pheromones are generally believed to be produced in the mandibular glands, although definitive experimental proof has never been provided. We tested the trail following behavior of recruits of Trigona recursa in field experiments with artificial scent trails branching off from natural scent trails of this stingless bee. First-time recruits (newcomers) did not follow these trails when they were laid with pure solvent or mandibular gland extract. However, they did follow trails made with labial gland extract. Chemical analyses of labial gland secretions revealed that hexyl decanoate was the dominant component (72.4 +/- 1.9% of all volatiles). Newcomers were significantly attracted to artificial trails made with synthetic hexyl decanoate, demonstrating its key function in eliciting scent-following behavior. According to our experiments with T. recursa, the trail pheromone is produced in the labial glands and not in the mandibular glands. Hexyl decanoate is the first component of a trail pheromone identified and proved to be behaviorally active in stingless bees.

    Anabolic androgenic steroids (AAS) are often misused by adolescents and athletes. Their effects vary according to chemical structure and metabolism, route of administration, and AAS regimen. In this study, adult C57Bl/6 male mice were systemically exposed to testosterone propionate (TP), nandrolone or 17alpha-methyltestosterone (17alpha-meT), type I, type II and type III AAS, respectively, in order to determine the hedonic or aversive properties of each drug. For this purpose, the conditioned place preference (CPP) test was employed at three different AAS doses (0.075, 0.75 and 7.5 mg/kg). Other behavioral domains monitored were light-dark transitions (side changes) and general activity. TP shifted place preference at all doses tested, and nandrolone shifted place preference at 0.75 and 7.5 mg/kg, but not at 0.075 mg/kg, the lower dose tested. Conversely, mice receiving 17alpha-meT did not show alteration in the preference score. The lower dose of nandrolone did modify exploratory-based anxiety showing a decrease in light-dark transitions if compared to vehicle-treated animals, while mice treated with TP or 17alpha-meT were not affected. Our data suggest that when studying hedonic and rewarding properties of synthetic androgens, distinction has to be made based on type of AAS and metabolism.

    The abuse of anabolic androgenic steroids (AASs), such as nandrolone, is not only a problem in the world of sports but is associated with the polydrug use of non-athletes. Among other adverse effects, AAS abuse has been associated with long term or even persistent psychiatric problems. We have previously found that nandrolone decanoate treatment could produce prolonged changes in rats' brain reward circuits associated to drug dependence. The aim in this study was to evaluate whether AAS-induced neurochemical and behavioral changes are reversible. The increases in extracellular dopamine (DA) and serotonin (5-HT) concentration, as well as stereotyped behavior and locomotor activity (LMA) evoked by cocaine were attenuated by pretreatment with nandrolone. The recovery period, which was needed for the DA system to return back to the basic level, was fairly long compared to the dosing period of the steroid. In the 5-HT system, the time that system needed to return back to the basal level, was even longer than in the DA system. The attenuation was still seen though there were no detectable traces of nandrolone in the blood samples. Given that accumbal outflow of DA and 5-HT, as well as LMA and stereotyped behavior are all related to reward of stimulant drugs, this study suggests that nandrolone decanoate has significant, long-lasting but reversible effects on the rewarding properties of cocaine.

Results revealed that T and ND significantly increased the weight of androgen target tissues as follows: ND was more influential on seminal vesicles, levator ani-bulbocavernosus muscle (LABC) and Cowper's glands and T (at a dose of 3.0 mg/kg.bw) influenced the weight of the ventral prostate and glans penis. Serum samples analyzed for steroid hormone levels showed the presence of 17β-testosterone, 17β-estradiol and 17β-nor-testosterone, in castrated male rats injected with testosterone and nortestosterone, but no significant differences were found between thyroid responses and thyroid hormone levels. The results of this research proved the disrupting activity of T and ND when administered in high doses and the useful application of the Hershberger bioassay in the case of ND. PMID:25302584

    Octanoic (C8) and decanoic (C10) acids are produced in hypoxic conditions by the yeast Saccharomyces cerevisiae as by-products of its metabolism and are considered fermentation inhibitors in the presence of ethanol at acidic pH. This study aims to broaden our understanding of the physiological limits between toxicity and ester production in yeast cells. To this end, the non-inhibitory concentration (NIC) and maximum inhibitory concentration (MIC) values were first established for C8 and C10 at physiological pH (5.8) without ethanol. The results showed that when these acids were added to culture medium at these values, they tended to accumulate in different cellular fractions of the yeast. While C8 was almost entirely located in the cell wall fraction, C10 was found in the endocellular fraction. Cell fatty acid detoxification was also different; while the esterification of fatty acids was more efficient in the case of C10, the peroxisome was activated regardless of which fatty acid was added. Furthermore, the study of the Pdr12 and Tpo1 transporters that evolved during the detoxification process revealed that C8 was mostly expelled by the Pdr12 carrier, which was related to higher β-oxidative damage in the presence of endocellular C10. C10 is more toxic at lower concentrations than C8. Although they are produced by yeast, the resulting intracellular medium-chain fatty acids (MCFAs) caused a level of toxicity which promoted cell death. However, MCFAs are involved in the production of beverage flavours.

    Muscle disuse produces severe atrophy and a slow-to-fast phenotype transition in the postural Soleus (Sol) muscle of rodents. Antioxidants, amino-acids and growth factors were ineffective to ameliorate muscle atrophy. Here we evaluate the effects of nandrolone (ND), an anabolic steroid, on mouse skeletal muscle atrophy induced by hindlimb unloading (HU). Mice were pre-treated for 2-weeks before HU and during the 2-weeks of HU. Muscle weight and total protein content were reduced in HU mice and a restoration of these parameters was found in ND-treated HU mice. The analysis of gene expression by real-time PCR demonstrates an increase of MuRF-1 during HU but minor involvement of other catabolic pathways. However, ND did not affect MuRF-1 expression. The evaluation of anabolic pathways showed no change in mTOR and eIF2-kinase mRNA expression, but the protein expression of the eukaryotic initiation factor eIF2 was reduced during HU and restored by ND. Moreover we found an involvement of regenerative pathways, since the increase of MyoD observed after HU suggests the promotion of myogenic stem cell differentiation in response to atrophy. At the same time, Notch-1 expression was down-regulated. Interestingly, the ND treatment prevented changes in MyoD and Notch-1 expression. On the contrary, there was no evidence for an effect of ND on the change of muscle phenotype induced by HU, since no effect of treatment was observed on the resting gCl, restCa and contractile properties in Sol muscle. Accordingly, PGC1α and myosin heavy chain expression, indexes of the phenotype transition, were not restored in ND-treated HU mice. We hypothesize that ND is unable to directly affect the phenotype transition when the specialized motor unit firing pattern of stimulation is lacking. Nevertheless, through stimulation of protein synthesis, ND preserves protein content and muscle weight, which may result advantageous to the affected skeletal muscle for functional recovery.

    Nandrolone (17beta-hydroxy-4-estren-3-one, NAD) is an endogenous steroid hormone; thus, the detection of its metabolites is not conclusive of NAD doping in racehorses. NAD doping control in male horses is based on the threshold, namely, the concentration ratio of 5alpha-estran-3beta,17alpha-diol (ETA) to 5(10)-estren-3beta,17alpha-diol (ETE). The ETA/ETE ratio of 1/1 was determined based on statistical data of authentic horses in International Federation of Horseracing Authorities. To individuals with complex metabolic disorders, however, such a threshold might not be applicable. The aim of this study was to establish an analytical method that discriminates endogenous steroids from exogenous ones in horse urine after NAD administration using gas chromatography/combustion/carbon isotope ratio mass spectrometry (GC/C/IRMS). Urine was sampled from NAD-administered and authentic horses. Ten millilitres of urine was hydrolyzed and subjected to liquid-liquid extraction and solid phase extraction. The residue of the extracts purified by HPLC was derivatized by acetylation. As a result of measurement of the (13)C/(12)C ratio (delta(13)C) by GC/C/IRMS, the delta(13)C values of ETA for NAD-administered and authentic horses were -32.20+/-0.35 per thousand and -27.85+/-0.75 per thousand (n=60), respectively. The detection limit of ETA in this GC/C/IRMS analysis was approximately 25 ng/ml. This study indicates that the measurement of delta(13)C by GC/C/IRMS enables us to discriminate exogenous ETA derived from NAD administration from endogenous ETA, proving that GC/C/IRMS is a useful technique to complement the ETA/ETE ratio.

    Anabolic/androgenic steroids (AAS) are drugs that enhance muscle mass, and are often illegally utilized in athletes to improve their performances. Recent data suggest that the increased risk for amyotrophic lateral sclerosis (ALS) in male soccer and football players could be linked to AAS abuse. ALS is a motor neuron disease mainly occurring in sporadic (sALS) forms, but some familial forms (fALS) exist and have been linked to mutations in different genes. Some of these, in their wild type (wt) form, have been proposed as risk factors for sALS, i.e. superoxide dismutase 1 (SOD1) gene, whose mutations are causative of about 20% of fALS. Notably, SOD1 toxicity might occur both in motor neurons and in muscle cells. Using gastrocnemius muscles of mice overexpressing human mutant SOD1 (mutSOD1) at different disease stages, we found that the expression of a selected set of genes associated to muscle atrophy, MyoD, myogenin, atrogin-1, and transforming growth factor (TGF)β1, is up-regulated already at the presymptomatic stage. Atrogin-1 gene expression was increased also in mice overexpressing human wtSOD1. Similar alterations were found in axotomized mouse muscles and in cultured ALS myoblast models. In these ALS models, we then evaluated the pharmacological effects of the synthetic AAS nandrolone on the expression of the genes modified in ALS muscle. Nandrolone administration had no effects on MyoD, myogenin, and atrogin-1 expression, but it significantly increased TGFβ1 expression at disease onset. Altogether, these data suggest that, in fALS, muscle gene expression is altered at early stages, and AAS may exacerbate some of the alterations induced by SOD1 possibly acting as a contributing factor also in sALS.

    Chronic kidney disease is a microvascular complication of diabetes mellitus (DM). Anemia is an important clinical manifestation to treat chronic kidney disease. Many subjects with poor socio-economic status having chronic kidney disease (CKD) and anaemia in a developing country can not afford the treatment with erythropoietin. This study has designed to see the efficacy of Nandrolone, a cheaper alternative; in comparison with recombinant human erythropoietin for management of anemia of pre-dialysis diabetic chronic kidney disease. Sixty adult diabetic patients with anaemia of chronic kidney disease on conservative treatment [Not on Hemodialysis (HD)] were enrolled. Patients were divided into two groups (Group 1 and Group 2) of 30 patients each. Group 1 patients received nandrolone deaconate 50 mg deep intramuscular and Group 2 recombinant human erythropoietin 100 IU per kilogram of body weight subcutaneously once weekly. Patients of both group received oral supplements in order to maintain body iron stores. All the relevant haematological and renal parameters were evaluated at the end of 3rd & 6th months. There was a statistically significant rise in haemoglobin concentration, packed cell volume, in both groups. The rise in haemoglobin concentration, in Group 2 was more marked followed by Group 1, at the end of 3rd, and 6th months. Nandrolone, though not equally effective, may be considered as a valid alternative therapy for the treatment of anemia of pre-dialysis diabetic chronic kidney disease to that of erythropoietin.

    Under current European Union legislation the use of anabolic steroids in food-producing livestock is banned because of their long-term adverse effects on human health. We examined the expression profile of the immunohistochemical marker progesterone receptor in veal calves' sex accessory glands following experimental administration of anabolic compounds. The aim was to confirm the accuracy of the immunohistochemical approach in the detection of the over-expression of the progesterone receptor induced by the administration of sexual steroids at low levels (17β-estradiol and nandrolone alone or in combination). A total of 217 male veal calves were randomly divided into four groups: group A (104 calves) treated with 17β-estradiol (5 mg/head; 4 weekly injections); group B (20 calves) treated with nandrolone (50 mg/head; 4 weekly injections); group C (20 calves) treated with the association of the two steroids (5 mg estradiol + 50 mg nandrolone; 4 weekly injections); and group K (73 calves) kept as a control. All the sexual accessory glands were collected at the slaughterhouse (15 days after the last administration) and subjected to immunohistochemical staining with anti-progesterone receptor antibody. All the calves treated with 17β-estradiol alone or in association with nandrolone (groups A and C) showed strong positivity, while nandrolone-treated calves and controls (groups B and K) gave negative results to the immunohistochemical investigation. The statistical analysis showed that the progesterone receptor is a significant predictor of 17β-estradiol treatment alone or in association with nandrolone (p < 0.001): the immunohistochemical study resulted in 100% sensitivity (CI = 95%: 97.1-100%) and specificity (CI = 95%: 95.1-100%) for prostate and 99% sensitivity (CI = 95%: 95.6-100%) and 100% specificity (CI = 95%: 95.1-100%) for bulbo-urethral glands. The data confirm that this innovative biological approach offers a reliable tool to enhance the efficacy of

    This report attempts to highlight that use of an antipsychotic and concurrent chronic use of methamphetamine can cause drug-induced parkinsonism. Methamphetamine is usually not encountered in the list of agents that induce drug-induced parkinsonism and so its consideration particularly during chronic use by a patient who is also on an antipsychotic is worthwhile because of its popularity as an illegal narcotic. This case report describes just such a case of drug-induced parkinsonism which is a subacute syndrome that mimics Parkinson's disease. Although less alarming than dystonia, it is more common, more difficult to treat and can be the cause of significant disability during maintenance treatment especially in the elderly. In most cases, symptoms are reversible in days or weeks, but occasionally, especially in the elderly, or if long-acting injectable antipsychotics are used-as in this case-symptoms may last for weeks or months. The report also illustrates the neuronal workings due to chronic methamphetamine-use and the additive effects of dopamine blockade by antipsychotics such as haloperidol.

    Hyperandrogenism is the central feature of polycystic ovary syndrome (PCOS). Due to the intricate relationship between hyperandrogenism and insulin resistance in PCOS, 50%-70% of these patients also present with hyperinsulinemia. Metformin, an insulin sensitizer, has been used to reduce insulin resistance and improve fertility in women with PCOS. In previous work, we have noted that a dietary medium-chain fatty acid, decanoic acid (DA), improves glucose tolerance and lipid profile in a mouse model of diabetes. Here, we report for the first time that DA, like metformin, inhibits androgen biosynthesis in NCI-H295R steroidogenic cells by regulating the enzyme 3β-hydroxysteroid dehydrogenase/Δ5-Δ4-isomerase type 2 (HSD3B2). The inhibitory effect on HSD3B2 and androgen production required cAMP stimulation, suggesting a mechanistic action via the cAMP-stimulated pathway. Specifically, both DA and metformin reduced cAMP-enhanced recruitment of the orphan nuclear receptor Nur77 to the HSD3B2 promoter, coupled with decreased transcription and protein expression of HSD3B2. In a letrozole-induced PCOS rat model, treatment with DA or metformin reduced serum-free testosterone, lowered fasting insulin, and restored estrous cyclicity. In addition, DA treatment lowered serum total testosterone and decreased HSD3B2 protein expression in the adrenals and ovaries. We conclude that DA inhibits androgen biosynthesis via mechanisms resulting in the suppression of HSD3B2 expression, an effect consistently observed both in vitro and in vivo. The efficacy of DA in reversing the endocrine and metabolic abnormalities of the letrozole-induced PCOS rat model are promising, raising the possibility that diets including DA could be beneficial for the management of both hyperandrogenism and insulin resistance in PCOS.

    The bifunctional photoacid ω-(2-hydroxynaphthyl-1)-decanoic acid (1S2N) takes part both in intramolecular excited-state proton transfer (ESPT) to the anion of a fatty acid and in intermolecular ESPT in the presence of a water solvent. Excited-state intra- and intermolecular proton transfer of 1S2N was investigated in homogeneous ethanol/water solution and in micellar solutions of various surfactants. The interfacial potential of micelles was changed by using cationic (CTAB), non-ionic (Brij-35) and anionic (SDS) surfactants. With the decrease of the interfacial potential, the protolytic photodissociation of naphthol and the diffusion-controlled intramolecular ESPT to carboxylic anion were suppressed.

    The modeling of the oxidation of methyl esters was investigated and the specific chemistry, which is due to the presence of the ester group in this class of molecules, is described. New reactions and rate parameters were defined and included in the software EXGAS for the automatic generation of kinetic mechanisms. Models generated with EXGAS were successfully validated against data from the literature (oxidation of methyl hexanoate and methyl heptanoate in a jet-stirred reactor) and a new set of experimental results for methyl decanoate. The oxidation of this last species was investigated in a jet-stirred reactor at temperatures from 500 to 1100 K, including the negative temperature coefficient region, under stoichiometric conditions, at a pressure of 1.06 bar and for a residence time of 1.5 s: more than 30 reaction products, including olefins, unsaturated esters, and cyclic ethers, were quantified and successfully simulated. Flow rate analysis showed that reactions pathways for the oxidation of methyl esters in the low-temperature range are similar to that of alkanes. (author)

    Anabolic-androgenic steroid (AAS) compounds are synthetic androgens taken by athletes to increase physical strength and endurance. Recent studies in our laboratory have demonstrated that AAS administration disrupts the estrous cycle of Long-Evans rats. The present experiments examined the effects of six commonly abused AAS compounds on sexual receptivity in ovariectomized rats. Adult female Long-Evans rats received estradiol benzoate (EB; 2.0 micrograms/day s.c.) for 6 consecutive days followed by 15 days of EB concurrent with daily s.c. injections of 7.5 mg/kg of one of the following AAS compounds: 17 alpha-methyltestosterone, methandrostenolone, nandrolone decanoate, stanozolol, oxymetholone, testosterone cypionate, or the oil vehicle. On Day 15, all female rats received progesterone (1.0 mg/rat) 4 h before testing. Tests for sexual receptivity were conducted on Days 3, 6, 14, and 15 of AAS treatment. Although the time course of AAS effects on sexual receptivity varied, some overall effects were clear. For example, 17 alpha-methyltestosterone, methandrostenolone, nandrolone decanoate, and stanozolol interfered with the display of sexual receptivity on Day 14, whereas oxymetholone and testosterone cypionate had no effect. Rats in all groups displayed high levels of sexual receptivity after receiving progesterone on Day 15. Our results show that AAS compounds vary in their degree of inhibition of female sexual behavior in ovariectomized rats. PMID:9454671

    The anabolic steroid nandrolone decanoate has been reported to increase voluntary ethanol intake in Wistar rats. In recent experiments we received opposite results, with decreased voluntary ethanol intake in both high drinking AA and low drinking Wistar rats after nandrolone treatment. The difference between the two studies was that we used pure nandrolone decanoate in oil, whereas in the previous study the nandrolone product Deca-Durabolin containing benzyl alcohol (BA) was used. The aims of the present study were to clarify whether the BA treatment could promote ethanol drinking and to assess the role of the hypothalamic-pituitary-adrenal-gonadal axes (HPAGA) in the potential BA effect. Male AA and Wistar rats received subcutaneously BA or vehicle oil for 14 days. Hereafter followed a 1-week washout and consecutively a 3-week voluntary alcohol consumption period. The median (± median absolute deviation) voluntary ethanol consumption during the drinking period was higher in BA-treated than in control rats (4.94 ± 1.31 g/kg/day vs. 4.17 ± 0.31 g/kg/day, p = 0.07 and 1.01 ± 0.26 g/kg/day vs. 0.38 ± 0.27 g/kg/day, p = 0.05, for AA and Wistar rats, respectively; combined effect p < 0.01). The present results can explain the previous discrepancy between the two nandrolone studies. No significant BA effects on basal and ethanol-mediated serum testosterone and corticosterone levels were observed in blood samples taken at days 1, 8 and 22. However, 2h after ethanol administration significantly (p = 0.02) higher frequency of testosterone elevations was detected in high drinking AA rats compared to low drinking Wistars, which supports our previous hypotheses of a role of testosterone elevation in promoting ethanol drinking. Skin irritation and dermatitis were shown exclusively in the BA-treated animals. Altogether, the present results indicate that earlier findings obtained with Deca-Durabolin containing BA need to be re-evaluated.

    Background For treatment of patients diagnosed with schizophrenia, comparative long-term effectiveness of antipsychotic drugs to reduce relapses when minimising adverse effects is of clinical interest, hence prompting this review. Aims To evaluate the comparative long-term effectiveness of antipsychotic drugs. Method We systematically searched electronic databases for reports of randomised controlled trials (RCTs) of antipsychotic monotherapy aimed at reducing relapse risks in schizophrenia. We conducted network meta-analysis of 18 antipsychotics and placebo. Results Studies of 10 177 patients in 56 reports were included; treatment duration averaged 48 weeks (range 4–156). Olanzapine was significantly more effective than chlorpromazine (odds ratio (OR) 0.35, 95% CI 0.14–0.88) or haloperidol (OR=0.50, 95% CI 0.30–0.82); and fluphenazine decanoate was more effective than chlorpromazine (OR=0.31, 95% CI 0.11–0.88) in relapse reduction. Fluphenazine decanoate, haloperidol, haloperidol decanoate and trifluoperazine produced more extrapyramidal adverse effects than olanzapine or quetiapine; and olanzapine was associated with more weight gain than other agents. Conclusions Except for apparent superiority of olanzapine and fluphenazine decanoate over chlorpromazine, most agents showed intermediate efficacy for relapse prevention and differences among them were minor. Typical antipsychotics yielded adverse neurological effects, and olanzapine was associated with weight gain. The findings may contribute to evidence-based treatment selection for patients with chronic psychotic disorders. Declaration of interest R.J.B. received grants from the Bruce J.

    The effect of treatment with an anabolic steroid (nandrolone decanoate) on the muscle mass of plantaris and soleus of a rats in hindlimb suspension, and on the isomyosin expression in these muscles, was investigated in young female rats divided into four groups: normal control (NC), normal steroid (NS), normal suspension (N-sus), and suspension steroid (sus-S). Steroid treatment of suspended animals (sus-S vs N-sus) was found to partially spare body weight and muscle weight, as well as myofibril content of plantaris (but not soleus), but did not modify the isomyosin pattern induced by suspension. In normal rats (NS vs NC), steroid treatment did enhance body weight and plantaris muscle weight; the treatment did not alter isomyosin expression in either muscle type.

    The present study investigated whether anabolic androgenic steroid (AAS) treatment (daily subcutaneous injections during 2 weeks with nandrolone decanoate; 15 mg/kg) affects competitive behaviour, and locomotor activity response to a sedative dose of ethanol (0.5 g ethanol/kg). In addition, levels of brain monoamines were assessed. The results showed that AAS treated animals exhibited enhanced dominant behaviour in the competition test compared to controls. The AAS groups' locomotor activity was not affected by ethanol in contrast to the controls who showed a sedative locomotor activity. AAS animals had significant lower levels of serotonin in basal forebrain and dorsal striatum compared to controls. These findings further strengthen the fact that AAS affects behaviour, as well as biochemical parameters. Based on previous studies and results from the present study, we hypothesize that AAS abuse may constitute a risk factor for disinhibitory behaviour, partly by affecting the serotonergic system.

    Six separate experiments were conducted which examined the effects of long-term administration of anabolic-androgenic steroid (AAS) compounds on the sexual behavior of gonadally intact male rats. The six AAS compounds analyzed in this study were 17alpha-methyltestosterone, methandrostenolone, nandrolone decanoate, stanozolol, oxymetholone, and testosterone cypionate. In each experiment, subjects received daily injections of a high, medium, or low dose of the AAS compound, or the oil vehicle, for 12 weeks. Sexual behavior was quantified weekly. Twelve weeks of administration of the high dose of three AAS compounds, 17alpha-methyltestosterone, stanozolol, and oxymetholone, eliminated male sexual behavior. These treatments also suppressed serum testosterone levels. The remaining compounds had minimal effects on sexual behavior at any dose. Thus, in intact male rats the six AAS compounds examined in these studies evoked a range of behavioral and endocrine responses that varied as a function of the specific compound and dose administered.

    Anabolic androgenic steroids (AAS) are synthetic derivatives of testosterone with thrombogenic potential in high doses and long-term administration. Taurine, a widely distributed amino-sulfonic acid, is known for its beneficial effects in hypercoagulable states. In order to assess the impact of chronic administration of high doses of AAS and taurine upon haemostasis process in rats, 40 male Wistar rats were divided into four equal groups: control group (group C) - no treatment; androgen group (group A) - received 10 mg/kg per week of nandrolone decanoate (DECA); taurine (group T) - received oral supplementation of 2% taurine in drinking water; androgen and taurine group (group AT) - concomitant administration of DECA and taurine. After 12 weeks, blood samples were collected and haemostasis parameters were assessed with the thrombelastographic (TEG) analysis system: reaction time, clot kinetics (K, α), final clot strength, coagulation index and the clot lysis (Ly30). Nandrolone significantly decreased reaction time in group A compared with control (P<0.001), whereas taurine significantly increase reaction time (P=0.01), and this effect was maintained in group AT compared with group A (P=0.009). Similar differences between groups have been recorded for the clot kinetics parameters K, α. The final clot strength and coagulation index were significantly increased in group A versus group C (P=0.04, respectively P<0.001), but not in group AT versus group C (P>0.05). There were no differences in clot lysis, as shown by Ly30. Nandrolone produces an accelerated clot development and an increased clot firmness in Wistar rats. Taurine association ensures a protective effect against this hypercoagulable state, partially restoring the altered parameters of the coagulation profile. PMID:23160242

    Medium-chain acyl-CoA dehydrogenase (MCAD) deficiency is biochemically characterized by tissue accumulation of octanoic (OA), decanoic (DA) and cis-4-decenoic (cDA) acids, as well as by their carnitine by-products. Untreated patients present episodic encephalopathic crises and biochemical liver alterations, whose pathophysiology is poorly known. We investigated the effects of OA, DA, cDA, octanoylcarnitine (OC) and decanoylcarnitine (DC) on critical mitochondrial functions in rat brain and liver. DA and cDA increased resting respiration and diminished ADP- and CCCP-stimulated respiration and complexes II-III and IV activities in both tissues. The data indicate that these compounds behave as uncouplers and metabolic inhibitors of oxidative phosphorylation. Noteworthy, metabolic inhibition was more evident in brain as compared to liver. DA and cDA also markedly decreased mitochondrial membrane potential, NAD(P)H content and Ca(2+) retention capacity in Ca(2+)-loaded brain and liver mitochondria. The reduction of Ca(2+) retention capacity was more pronounced in liver and totally prevented by cyclosporine A and ADP, as well as by ruthenium red, demonstrating the involvement of mitochondrial permeability transition (mPT) and Ca(2+). Furthermore, cDA induced lipid peroxidation in brain and liver mitochondria and increased hydrogen peroxide formation in brain, suggesting the participation of oxidative damage in cDA-induced alterations. Interestingly, OA, OC and DC did not alter the evaluated parameters, implying lower toxicity for these compounds. Our results suggest that DA and cDA, in contrast to OA and medium-chain acylcarnitines, disturb important mitochondrial functions in brain and liver by multiple mechanisms that are possibly involved in the neuropathology and liver alterations observed in MCAD deficiency.

    Anabolic-androgenic steroid (AAS) effects on brain reward were investigated in male rats with electrodes implanted in the lateral hypothalamus using the rate-frequency curve shift paradigm of brain stimulation reward. In the first experiment, treatment for 2 weeks with the AAS methandrostenolone had no effect on either the reward or performance components of intracranial self-stimulation. In the second experiment, treatment for 15 weeks with an AAS "cocktail" consisting of testosterone cypionate, nandrolone decanoate, and boldenone undecylenate did not alter brain reward but did produce a slight but significant change in bar press rate. In addition to the AAS treatment, animals in the second study were administered a single injection of d-amphetamine before and after 15 weeks of AAS exposure. The rate-frequency curve shift observed in response to a systemic injection of amphetamine was significantly greater in animals after 15 weeks of treatment with the AAS cocktail. Although AAS do not appear to alter the rewarding properties of brain stimulation, AAS may influence the sensitivity of brain reward systems. PMID:8866980

    The effect of treatment with an anabolic steroid (nandrolone decanoate) on the muscle mass, the subcellular protein content, and the myosin patterns of normal overloaded and suspended overloaded plantaris muscle in female rat was investigated, dividing rats into six groups: normal control (NC), overload (OV), OV steroid (OV-S), normal suspended (N-sus), OV suspended (OV-sus), and OV suspended steroid (OV-sus-S). Relative to control values, overload produced a sparing effect on the muscle weight of the OV-sus group as well as increases of muscle weight of the OV group; increased protein content; and an increased expression of slow myosin in both OV and OV-sus groups. Steroid treatment of OV animals did not after the response of any parameter analyzed for the OV group, but in the OV-sus group steroid treatment induced increases in muscle weight and in protein content of the OV-sus-S group. The treatment did not alter the pattern of isomyosin expression observed in the OV or the OV-sus groups. These result suggest that the steroid acts synergistically with functional overload only under conditions in which the effect of overload is minimized by suspension.

    Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by selective loss of upper and lower motor neurons and skeletal muscle atrophy. Epidemiologic and experimental evidence suggest the involvement of androgens in ALS pathogenesis, but the mechanism through which androgens modify the ALS phenotype is unknown. Here, we show that androgen ablation by surgical castration extends survival and disease duration of a transgenic mouse model of ALS expressing mutant human SOD1 (hSOD1-G93A). Furthermore, long-term treatment of orchiectomized hSOD1-G93A mice with nandrolone decanoate (ND), an anabolic androgenic steroid, worsened disease manifestations. ND treatment induced muscle fiber hypertrophy but caused motor neuron death. ND negatively affected survival, thereby dissociating skeletal muscle pathology from life span in this ALS mouse model. Interestingly, orchiectomy decreased androgen receptor levels in the spinal cord and muscle, whereas ND treatment had the opposite effect. Notably, stimulation with ND promoted the recruitment of endogenous androgen receptor into biochemical complexes that were insoluble in sodium dodecyl sulfate, a finding consistent with protein aggregation. Overall, our results shed light on the role of androgens as modifiers of ALS pathogenesis via dysregulation of androgen receptor homeostasis.

    A functional interrelation between the nervous and endocrine systems has been established. However, few studies have dealt with the effects of sexual steroids on learning and memory. The aim of this work was to determine whether sexual steroid hormones could modulate the extinction response of a passive avoidance conditioning in rats. Male Wistar rats, randomly assigned to five groups, two controls and three experimental groups, were submitted to a one-trial passive avoidance conditioning and tested for their retention 24 hr after and during 10 weeks. One control group received no treatment at all, the other received vegetable oil, and the three experimental received 20 mg of testosterone enanthate, 0.8 mg estradiol valerate, or 4 mg nandrolone decanoate, respectively. All substances were applied in a 0.3 ml volume, 24 hours before training and before testing for retention each week during 10 weeks. Results indicate that the extinction process is modulated by these hormones, since testosterone and estradiol facilitate extinction, whereas the anabolic androgen produced a resistance to the extinction process.

  2. Critical evaluation of the role of nutritional support with chemotherapy.

    Although weight loss has an adverse impact on cancer patient survival, the ability of caloric provision via total parenteral nutrition (TPN) to favorably influence outcome in chemotherapy-treated populations is not established. In randomized trials, no significant improvement in either response or survival was associated with TPN addition to chemotherapeutic treatment of adult patients with lymphoma, sarcoma, colon cancer, adenocarcinoma and small cell carcinoma of the lung, or testicular carcinoma. In two instances, TPN addition was associated with decreased survival, again raising the concern that caloric support in the absence of effective antitumor therapy might stimulate cancer growth. In any event, the hypothesis that nutritional repletion of a malnourished cancer patient receiving chemotherapy will improve clinical outcome remains to be critically tested, as studies demonstrating sequential improvement in lean body mass have not been reported. Most recently, consideration of potential mechanisms underlying the development of cancer cachexia has led to new strategies for nutritional intervention. For example, hypogonadism or low testosterone levels have been described in male patient populations with advanced cancer and correlated with weight loss and adverse outcome, leading to trial of replacement therapy with nandrolone decanoate. Similarly, the frequent identification of abnormal glucose metabolism in the patients with cancer cachexia has stimulated clinical trials with agents such as hydrazine sulfate and insulin designed to reverse the metabolic abnormality. Whether such efforts designed to alter metabolic abnormalities associated with cancer cachexia will improve clinical outcome will be determined in ongoing clinical trials.

    Background Spinal cord injury (SCI) causes severe bone loss. At present, there is no practical treatment to delay or prevent bone loss in individuals with motor-complete SCI. Hypogonadism is common in men after SCI and may exacerbate bone loss. The anabolic steroid nandrolone reduces bone loss due to microgravity or nerve transection. Objective To determine whether nandrolone reduced bone loss after SCI and, if so, to explore the mechanisms of nandrolone action. Methods Male rats with complete transection of the spinal cord were administered nandrolone combined with a physiological replacement dose of testosterone, or vehicle, beginning on day 29 after SCI and continued for 28 days. Results SCI reduced distal femoral and proximal tibial bone mineral density (BMD) by 25 and 16%, respectively, at 56 days. This bone loss was attenuated by nandrolone. In ex vivo osteoclasts cultures, SCI increased mRNA levels for tartrate-resistant acid phosphatase (TRAP) and calcitonin receptor; nandrolone-normalized expression levels of these transcripts. In ex vivo osteoblast cultures, SCI increased receptor activator of NF-kB ligand (RANKL) mRNA levels but did not alter osteoprotegerin (OPG) mRNA expression; nandrolone-increased expression of OPG and OPG/RANKL ratio. SCI reduced mRNA levels of Wnt signaling-related genes Wnt3a, low-density lipoprotein receptor-related protein 5 (LRP5), Fzd5, Tcf7, and ectodermal-neural cortex 1 (ENC1) in osteoblasts, whereas nandrolone increased expression of each of these genes. Conclusions The results demonstrate that nandrolone reduces bone loss after SCI. A potential mechanism is suggested by our findings wherein nandrolone modulates genes for differentiation and activity of osteoclasts and osteoblasts, at least in part, through the activation of Wnt signaling.

    The effects of treating groups of rats with four different anabolic androgenic steroids (AAS) (testosterone, nandrolone, methandrostenolone, and oxymetholone) on 5-hydroxytryptamine (5-HT) and dopamine (DA) neurones in different brain regions were examined. The AAS was injected six times with 1 week's interval and the rats were sacrificed 2 days after the final injection. 5-HT and its metabolite 5-hydroxyindoleacetic acid (5-HIAA), DA and its metabolites 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA) were measured. The effect on DA and 5-HT synthesis rate was analysed as the accumulation of 3,4-dihydroxyphenyl-alanine (DOPA) and 5-hydroxytryptophan (5-HTP), respectively, after inhibition of the amino acid decarboxylase with NSD-1015 (3-hydroxy-benzylhydrazine dihydrochloride). Additionally, the monoamine oxidase (MAO) activity was analysed in the hypothalamus. The DOPAC+HVA/DA ratio was increased in the striatum in all treatment groups. However, the synthesis rate of DA was significantly increased only in the methandrostenolone treated group. The 5-HIAA/5-HT ratio was increased in all treatment groups in the hippocampus, in the frontal cortex in the methandrostenolone-treated animals and in the hypothalamus in the testosterone- and oxymetholone-treated rats, while the 5-HT synthesis rate was not affected by the AAS-treatments. The MAO-A activity was increased in the oxymetholone-treated rats while the other treatment groups were unaffected. The MAO-B activity was not changed. The results indicate that relatively high doses of AAS increase dopaminergic and 5-hydroxytryptaminergic metabolism in male rat brain, probably due to enhanced turnover in these monaminergic systems.

    In the past several decades, the therapeutic use of anabolic androgenic steroids (AAS) has been overshadowed by illicit use of these drugs by elite athletes and a growing number of adolescents to enhance performance and body image. As with adults, AAS use by adolescents is associated with a range of behavioral effects, including increased anxiety and altered responses to stress. It has been suggested that adolescents, especially adolescent females, may be particularly susceptible to the effects of these steroids, but few experiments in animal models have been performed to test this assertion. Here we show that chronic exposure of adolescent female mice to a mixture of three commonly abused AAS (testosterone cypionate, nandrolone decanoate and methandrostenolone; 7.5 mg/kg/day for 5 days) significantly enhanced anxiety-like behavior as assessed by the acoustic startle response (ASR), but did not augment the fear-potentiated startle response (FPS) or alter sensorimotor gating as assessed by prepulse inhibition of the acoustic startle response (PPI). AAS treatment also significantly increased the levels of corticotropin releasing factor (CRF) mRNA and somal-associated CRF immunoreactivity in the central nucleus of the amygdala (CeA), as well as neuropil-associated immunoreactivity in the dorsal aspect of the anterolateral division of the bed nucleus of the stria terminalis (dBnST). AAS treatment did not alter CRF receptor 1 or 2 mRNA in either the CeA or the dBnST; CRF immunoreactivity in the ventral BnST, the paraventricular nucleus (PVN) or the median eminence (ME); or peripheral levels of corticosterone. These results suggest that chronic AAS treatment of adolescent female mice may enhance generalized anxiety, but not sensorimotor gating or learned fear, via a mechanism that involves increased CRF-mediated signaling from CeA neurons projecting to the dBnST.

    Anabolic androgenic steroids (AAS) use by adolescents is steadily increasing. Adolescence involves remodeling of steroid-sensitive neural circuits that mediate social behaviors, and previous studies using animal models document effects of AAS on male social behaviors. The present experiments tested whether AAS have persistent and more pronounced behavioral consequences when drug exposure occurs during adolescence as compared to exposure in adulthood. Male Syrian hamsters were injected daily for 14 days with either vehicle or an AAS cocktail containing testosterone cypionate (2 mg/kg), nandrolone decanoate (2 mg/kg), and boldenone undecylenate (1 mg/kg), either during adolescence (27-41 days of age) or adulthood (63-77 days of age). As adults, subjects were tested two or four weeks after the last injection for either sexual behavior with a receptive female or male-male agonistic behavior in a resident-intruder test. Compared with vehicle-treated males, AAS-treated males, regardless of age of treatment, displayed fewer long intromissions and a significant increase in latency to the first long intromission, indicative of reduced potential to reach sexual satiety. Increased aggression was observed in males exposed to AAS compared with males treated with vehicle, independently of age of AAS treatment. However, unlike hamsters exposed to AAS in adulthood, hamsters exposed to AAS during adolescence did not display any submissive or risk-assessment behaviors up to 4 weeks after discontinuation of AAS treatment. Thus, AAS have long-lasting effects on male sexual and agonistic behaviors, with AAS exposure during adolescence resulting in a more pronounced reduction in submissive behavior compared to AAS exposure in adulthood.

    Many athletes use drugs, especially anabolic androgenic steroids (AAS), but there are few reports on the endocrinological and pathological changes in AAS abusers. In this study we reported the results of endocrinological examinations in rats administered AAS and also physical changes. We separated 37 male Wistar rats (7 weeks old) into 3 groups: Group A was medicated with nandrolone decanoate, metenolone acetate, and dromostanolone; Group B with nandrolone decanoate and saline; and Group C was given only saline. They were given subcutaneous injections of the medications or the control vehicle once a week for 6 weeks. Medications were stopped for 4 weeks, and then resumed for another 6 weeks. After that, rats were sacrificed. Serum testosterone level in Group A was significantly higher than that in Group C. Serum dihydrotestosterone in Group A was significantly higher than that in both Groups B and C. Serum estradiol-17beta levels in Groups A and B were significantly higher than that in Group C. In pathological evaluation, heart, testis, and adrenal gland were severely damaged. These findings indicate that there is a high degree of risk related to the use of AAS.

    The use of anabolic androgenic steroids is often associated with the use of other substances, licit or not, such as nicotine present in the tobacco. The present study investigated for the first time the effects of co-administration of synthetic steroids and nicotine on the ovarian and uterine tissue and fertility of adult female rats. Animals were submitted to treatment groups (n=16/group): nandrolone decanoate (ND; 7.5mg/kg BW/week); testosterone mixture (T; 7.5mg/kg BW/week); nicotine (N; 2.0mg/kg BW/day), and co-administration of ND/N, T/N and ND/T/N. The control group received saline solution daily. The injections were administered subcutaneously for 30 consecutive days. Results demonstrated that all androgenized rats exhibited estral acyclicity and there was suppression of reproductive capacity due to notable ovarian and uterine histological changes. Treatments promoted decrease (p<0.05) in the ovarian weight. Uterine weight increased (p<0.05) in the T and T/N groups, in comparison to control group. ND or T co-administered or not to nicotine promoted intense follicular degeneration, with formation of cysts in the ovaries. High levels of circulating androgens in the ND/T/N group induced the presence of ovarian sex cord-stromal tumors of Sertoli cell pattern. Androgenized females presented endometrial changes characterized by papilliferous or pleated luminal epithelium, oedematous and hemorrhagic stroma and presence of gland cysts. In conclusion, the co-administration of three drugs promoted atypical morphological pattern on the ovaries and uterus of female rats. PMID:24556002

    We investigated whether morphological brain changes occurred in brain regions associated with body-weight homeostasis during acute antipsychotic treatment, and if so, whether they were related to changes in body mass and metabolic profile. Twenty-two antipsychotic-naive patients with first-episode schizophrenia received either risperidone long acting injection or flupenthixol decanoate over 13 weeks and were compared by structural MRI with 23 matched healthy volunteers at weeks 0, 4 and 13. Images were reconstructed using freesurfer fully-automated whole brain segmentation. The ventral diencephalon and prefrontal cortex were selected to represent the homeostatic and hedonic food intake regulatory systems respectively. Body mass was measured at weeks 0, 7 and 13 and fasting glucose and lipid profiles at weeks 0 and 13. Linear mixed effect models indicated significant group(⁎)time interactions for the ventral diencephalon volumes bilaterally. Ventral diencephalon volume reduction was strongly correlated bilaterally with body mass increase and HDL-cholesterol reductions, and unilaterally with blood glucose elevation. There were no significant changes in prefrontal cortical thickness. These findings implicate the ventral diencephalon, of which the hypothalamus is the main component, in the acute adipogenic and dyslipidaemic effects of antipsychotic medication. PMID:26184461

    Objectives: To investigate the effects of two different regimens of androgenic-anabolic steroid (AAS) administration on serum lipid and lipoproteins, and recovery of these variables after drug cessation, as indicators of the risk for cardiovascular disease in healthy male strength athletes. Methods: In a non-blinded study (study 1) serum lipoproteins and lipids were assessed in 19 subjects who self administered AASs for eight or 14 weeks, and in 16 non-using volunteers. In a randomised double blind, placebo controlled design, the effects of intramuscular administration of nandrolone decanoate (200 mg/week) for eight weeks on the same variables in 16 bodybuilders were studied (study 2). Fasting serum concentrations of total cholesterol, triglycerides, HDL-cholesterol (HDL-C), HDL2-cholesterol (HDL2-C), HDL3-cholesterol (HDL3-C), apolipoprotein A1 (Apo-A1), apolipoprotein B (Apo-B), and lipoprotein (a) (Lp(a)) were determined. Results: In study 1 AAS administration led to decreases in serum concentrations of HDL-C (from 1.08 (0.30) to 0.43 (0.22) mmol/l), HDL2-C (from 0.21 (0.18) to 0.05 (0.03) mmol/l), HDL3-C (from 0.87 (0.24) to 0.40 (0.20) mmol/l, and Apo-A1 (from 1.41 (0.27) to 0.71 (0.34) g/l), whereas Apo-B increased from 0.96 (0.13) to 1.32 (0.28) g/l. Serum Lp(a) declined from 189 (315) to 32 (63) U/l. Total cholesterol and triglycerides did not change significantly. Alterations after eight and 14 weeks of AAS administration were comparable. No changes occurred in the controls. Six weeks after AAS cessation, serum HDL-C, HDL2-C, Apo-A1, Apo-B, and Lp(a) had still not returned to baseline concentrations. Administration of AAS for 14 weeks was associated with slower recovery to pretreatment concentrations than administration for eight weeks. In study 2, nandrolone decanoate did not influence serum triglycerides, total cholesterol, HDL-C, HDL2-C, HDL3-C, Apo-A1, and Apo-B concentrations after four and eight weeks of intervention, nor six weeks after withdrawal

    Anabolic-androgenic steroids (AAS) are increasingly being used by athletes and youngsters to become masculine and to loose body fat. Long-term consumption of AAS causes multiple physical and psychological morbidities. Research has also concluded that AAS have addictive potential and AAS abuse is commonly found with other substance abuse. Abuse of AAS is rare in eastern countries. Abuse among women is even rarer. Here is a case report of an Indian woman, who was prescribed nandrolone decanoate injections by an unqualified medical practitioner to treat multiple non-specific somatic pains and reported weakness, leading to dependence for nandrolonedecanoate. This case report supports the research finding of abuse potential of AAS, raises concern about the need for spreading the awareness about AAS abuse among medical professionals, regulating medical practice by unqualified practitioners, and strict legal check against AAS availability in developing countries.

    The detection of the abuse of anabolic steroids in equine sport is complicated by the endogenous nature of some of the abused steroids, such as testosterone and nandrolone. These steroids are commonly administered as intramuscular injections of esterified forms of the steroid, which prolongs their effects and improves bioavailability over oral dosing. The successful detection of an intact anabolic steroid ester therefore provides unequivocal proof of an illegal administration, as esterified forms are not found endogenously. Detection of intact anabolic steroid esters is possible in plasma samples but not, to date, in the traditional doping control matrix of urine. The analysis of equine mane hair for the detection of anabolic steroid esters has the potential to greatly extend the time period over which detection of abuse can be monitored. Equine mane hair samples were incubated in 0.1M phosphate buffer (pH 9.5) before anabolic steroids (testosterone, nandrolone, boldenone, trenbolone and stanozolol), anabolic steroid esters (esters of testosterone, nandrolone, boldenone and trenbolone) and associated compounds (fluticasone propionate and esters of hydroxyprogesterone) were extracted by liquid-liquid extraction with a mix of hexane and ethyl acetate (7:3, v:v). Further sample clean up by solid phase extraction was followed by derivatisation with methoxylamine HCL and analysis by UHPLC-MS/MS. Initial method development was performed on a representative suite of four testosterone esters (propionate, phenylpropionate, isocaproate and decanoate) and the method was later extended to include a further 18 compounds. The applicability of the method was demonstrated by the analysis of mane hair samples collected following the intramuscular administration of 500 mg of Durateston(®) (mixed testosterone esters) to a Thoroughbred mare (560 kg). The method was subsequently used to successfully detect boldenone undecylenate and stanozolol in hair samples collected following

    A million gallon-a-day sewage treatment plant in Huntington Beach, CA converts solid sewage to activated carbon which then treats incoming waste water. The plant is scaled up 100 times from a mobile unit NASA installed a year ago; another 100-fold scale-up will be required if technique is employed for widespread urban sewage treatment. This unique sewage-plant employed a serendipitous outgrowth of a need to manufacture activated carbon for rocket engine insulation. The process already exceeds new Environmental Protection Agency Standards Capital costs by 25% compared with conventional secondary treatment plants.

    Home Treatment (HT) means acute psychiatric treatment in the patient's usual environment. Conceptually, HT is to be differentiated from other home-based services: It is limited with regard to duration and multiprofessional (e. g. psychiatrist plus psychiatric nursing staff plus social worker); the "24/7"-accessibility is frequently provided by the corresponding background hospital infrastructure. Target group are acutely mentally ill persons with an indication to inpatient treatment, who are willing to cooperate, and absence of endangerment to self and others. In contrast to the Scandinavian and many Anglophone countries where nationwide HT services are delivered, there are not many HT sites in Germany so far. Consequently, empirical data concerning HT in Germany is scarce. In summary, international studies show equivalent effects on psychopathological measures compared to inpatient treatment, reductions with regard to inpatient days, higher patient satisfaction and a trend towards cost-effectivity.

    Non-steroidal drugs that increase endogenous testosterone (T) may be used to exploit ergogenic effects of androgens in power sports. While superactive GnRH analog use is suspected, neither screening nor detection tests are developed. This study aimed to determine if (a) stimulation for 5 days by leuprolide (a superactive GnRH analog) of serum and urine steroids and urine LH is reproducible at a 2 week interval, (b) nandrolone decanoate (ND) co-administration masks responses to leuprolide administration, (c) performance of urine measurement of leuprolide and M1, its major metabolite, as a detection test. Healthy men were randomized into a 4 week parallel group, open label clinical study in which all men had daily sc injections of leuprolide (1mg) for 4 days in the 1st and 3rd weeks with hormone-free 2nd and 4th weeks. In the 3rd week, men were randomized to either ND injections or no extra treatment. Serum steroids were determined by liquid chromatography, tandem mass spectrometry (LC-MS), urine steroids by gas chromatography, mass spectrometry (GC-MS), urine leuprolide and M1 by high resolution LC-MS and urine LH by immunoassay. Leuprolide stimulated striking, reproducible increases in serum and urine LH and steroids (serum T, dihydroT (DHT), 3α diol; urine T, epitestosterone (E) and androsterone (A). ND suppressed basal serum T, E2, 3α diol, and urinary E but did not mask or change the magnitude of responses to leuprolide. Urine leuprolide and M1 measurement had 100% sensitivity and specificity in detecting leuprolide administration up to one day after cessation of injections with the detection window between 1 and 3 days after last dose. Screening using urine steroid and LH measurements, optimally by urinary log10(LHxT), correctly classified 82% of urine samples. It is concluded that leuprolide stimulation of endogenous testosterone is reproducible after a 10-day interval, is not masked by ND and is reliably detected by urine leuprolide or M1 measurement for at

  10. Lactate dehydrogenase regulation in aged skeletal muscle: Regulation by anabolic steroids and functional overload.

    Aging alters the skeletal muscle response to overload-induced growth. The onset of functional overload is characterized by increased myoblast proliferation and an altered muscle metabolic profile. The onset of functional overload is associated with increased energy demands that are met through the interconversion of lactate and pyruvate via the activity of lactate dehydrogenase (LDH). Testosterone targets many of the processes activated at the onset of functional overload. However, the effect of aging on this metabolic plasticity at the onset of functional overload and how anabolic steroid administration modulates this response is not well understood. The purpose of this study was to determine if aging would alter overload-induced LDH activity and expression at the onset of functional overload and whether anabolic steroid administration would modulate this response. Five-month and 25-month male Fischer 344xF1 BRN were given nandrolone decanoate (ND) or sham injections for 14days and then the plantaris was functionally overloaded (OV) for 3days by synergist ablation. Aging reduced muscle LDH-A & LDH-B activity 70% (p<0.05). Aging also reduced LDH-A mRNA abundance, however there was no age effect on LDH-B mRNA abundance. In 5-month muscle, both ND and OV decreased LDH-A and LDH-B activity. However, there was no synergistic or additive effect. In 5-month muscle, ND and OV decreased LDH-A mRNA expression with no change in LDH-B expression. In 25-month muscle, ND and OV increased LDH-A and LDH-B activity. LDH-A mRNA expression was not altered by ND or OV in aged muscle. However, there was a main effect of OV to decrease LDH-B mRNA expression. There was also an age-induced LDH isoform shift. ND and OV treatment increased the "fast" LDH isoforms in aged muscle, whereas ND and OV increased the "slow" isoforms in young muscle. Our study provides evidence that aging alters aspects of skeletal muscle metabolic plasticity normally induced by overload and anabolic steroid

    Stennis Space Center's aquaculture research program has led to an attractive wastewater treatment for private homes. The system consists of a septic tank or tanks for initial sewage processing and a natural secondary treatment facility for further processing of septic tanks' effluent, consisting of a narrow trench, which contains marsh plants and rocks, providing a place for microorganisms. Plants and microorganisms absorb and digest, thus cleansing partially processed wastewater. No odors are evident and cleaned effluent may be discharged into streams or drainage canals. The system is useful in rural areas, costs about $1,900, and requires less maintenance than mechanical systems.

    SUMMARY Considered to be an emerging endemic mycosis in Latin America, paracoccidioidomycosis is characterized by a chronic course and involvement of multiple organs in immunocompromised hosts. Infection sequelae are mainly related to pulmonary and adrenal insufficiency. The host-parasite interaction results in different expressions of the immune response depending on parasite pathogenicity, fungal load and genetic characteristics of the host. A few controlled and case series reports have shown that azoles and fast-acting sulfa derivatives are useful treatment alternatives in milder forms of the disease. For moderate/severe cases, more prolonged treatments or even parenteral routes are required especially when there is involvement of the digestive tract mucosa, resulting in poor drug absorption. Although comparative studies have reported that shorter treatment regimens with itraconazole are able to induce cure in chronically-infected patients, there are still treatment challenges such as the need for more controlled studies involving acute cases, the search for new drugs and combinations, and the search for compounds capable of modulating the immune response in severe cases as well as the paradoxical reactions.

    A simple surface treatment process is provided which offers a high performance surface for a variety of applications at low cost. This novel surface treatment, which is particularly useful for Ti-6Al-4V alloys, is achieved by forming oxides on the surface with a two-step chemical process and without mechanical abrasion. First, after solvent degreasing, sulfuric acid is used to generate a fresh titanium surface. Next, an alkaline perborate solution is used to form an oxide on the surface. This acid-followed-by-base treatment is cost effective and relatively safe to use in commercial applications. In addition, it is chromium-free, and has been successfully used with a sol-gel coating to afford a strong adhesive bond that exhibits excellent durability after the bonded specimens have been subjected to a harsh 72 hour water boil immersion. Phenylethynyl containing adhesives were used to evaluate this surface treatment with a novel coupling agent containing both trialkoxysilane and phenylethynyl groups. 8 Claims, 16 Drawing Sheets

    In the early 1970's, National Space Technology Laboratories discovered that water hyacinths literally thrive on sewage; they absorb and digest nutrients and minerals from wastewater, converting sewage effluents to clean water. They offer a means of purifying water at a fraction of the cost of a conventional sewage treatment plant, and provide a bonus value in byproducts. Hyacinths must be harvested at intervals; the harvested plants are used as fertilizers, high-protein animal feed and a source of energy. Already serving a number of small towns, the "aquaculture" technique has significantly advanced with its adoption by a major U.S. city.

    This invention provides for the anaerobic treatment of acidic petrochemical wastes in an anaerobic filter at high loadings and high recycle rates. The effluent from the top of the filter passes into a gas-disengaging/solids-settling zone containing a quiescent body of the effluent liquid. The settled solids are withdrawn and recycled to the base of the filter together with fresh acidic waste and an inorganic alkaline material (preferably magnesium oxide or carbonate) to maintain a neutral pH. The liquid portion of the effluent is sent to an aerobic digester to remove the rest of the organic material, which is used to support the growth of bacteria and fed back to the anaerobic system.

    PubMed

    2004-12-01

    Psychology has recently identified itself as a health care profession and codified this change in the bylaws of the American Psychological Association. Although psychologists make a number of contributions to the nation's health--and mental health--the most identifiable activity focuses on treating physical or psychological pathology with psychological interventions. Recently, health care policymakers have established that evidence supporting the efficacy of these interventions is more than sufficient for their inclusion in health care systems around the world. To promote faster and more widespread dissemination of these interventions specifically targeting problems severe enough to be included in health care systems and to solidify the identification of psychology as a health care profession, perhaps it is time for a change in terminology. It is proposed that psychologists label these procedures psychological treatments so as to differentiate them from more generic psychotherapy, which is often used outside of the scope of health care systems.

    Since the abuse of androgenic-anabolic steroids (AAS) has been associated with the occurrence of serious cardiovascular disease in young athletes, we performed two studies to investigate the effects of short-term AAS administration on heart structure and function in experienced male strength athletes, with special reference to dose and duration of drug abuse. In Study 1 the effects of AAS were assessed in 17 experienced male strength athletes (age 31 +/- 7 y) who self-administered AAS for 8 or 12 - 16 weeks and in 15 non-using strength athletes (age 33 +/- 5 y) in a non-blinded design. In Study 2 the effects of administration of nandrolone decanoate (200 mg/wk i. m.) for eight weeks were investigated in 16 bodybuilders in a randomised double blind, placebo controlled design. In all subjects M-mode and two-dimensional Doppler-echocardiography were performed at baseline and after 8 weeks AAS administration. In the athletes of Study 1 who used AAS for 12 - 16 weeks a third echocardiogram was also made at the end of the AAS administration period. Echocardiographic examinations included the determination of the aortic diameter (AD), left atrium diameter (LA), left ventricular end diastolic diameter (LVEDD), interventricular septum thickness (IVS), posterior wall end diastolic wall thickness (PWEDWT), left ventricular mass (LVM), left ventricular mass index (LVMI), ejection fraction (EF) and right ventricular diameter (RVD). For assessment of the diastolic function measurements of E and A peak velocities and calculation of E/A ratio were used. In addition, acceleration and deceleration times of the E-top (ATM and DT, respectively) were determined. For evaluation of factors associated with stroke volume the aorta peak flow (AV) and left ventricular ejection times (LVET) were determined. In Study 1 eight weeks AAS self-administration did not result in changes of blood pressure or cardiac size and function. Additionally, duration of AAS self-administration did not have any

    Androgens which are relatively cheap were used in the treatment of anaemia in dialysis patients before the advent of Erythropoietin (EPO). However, there are concerns about their efficacy and side effects. Aims. To examine the efficacy and harms of androgens for the treatment of anaemia of chronic kidney disease (CKD) compared to EPO. Settings and Design. A systematic review and meta-analysis using an a priori protocol. Methods and Materials. We searched several databases for randomized controlled trials using the key terms anaemia, chronic kidney disease, and androgens, without language restrictions. We also searched reference lists of relevant articles. Statistical Analysis Used. Data was analyzed using Review manger 5 software. We summarized treatment effects as relative risks and mean differences, with 95% confidence intervals using a random-effect model. We tested for heterogeneity with Chi(2) and the I(2) statistics. Results. We identified four eligible trials involving 114 participants, majority (83.33%) of whom were males, mostly over 50 years of age. The pooled difference in mean haemoglobin between the nandrolone and EPO arms at the end of the trials was -0.11 (CI -0.80 to 0.58) which is not statistically significant. Conclusions. This meta-analysis revealed no difference between nandrolone and EPO for the treatment of anaemia of CKD in men over 50 years. Therefore, nandrolone can be used for the treatment of anaemia of CKD in this category of patients, in resource-limited countries. However, further studies are needed to determine the long-term safety of nandrolone in men over 50 years old, as well as its effectiveness and safety in females in general, and males less than 50 years of age.

    The treatment of paraphilias remains a challenge in the mental health field. Combined pharmacologic and psychotherapeutic treatment is associated with better efficacy. The gold standard treatment of severe paraphilias in adult males is antiandrogen treatment with cognitive behavioral therapy. Selective serotonin reuptake inhibitors have been used in mild types of paraphilia and in cases of sexual compulsions and juvenile paraphilias. Antiandrogen treatments seem to be effective in severe paraphilic subjects committing sexual offenses. In particular, gonadotropin-releasing hormone analogs have shown high efficacy working in a similar way to physical castration but being reversible at any time. Treatment recommendations, side effects, and contraindications are discussed.

    The aim of this article is to give practicing physicians a practical approach to the treatment of latent and active tuberculosis. Most patients follow TB standard treatment recommended by WHO that depend on category of patient. It is a combination of four essential tuberculosis drugs of the first group: isoniazid, rifampicin, pyrazinamid and ethambutol; in some cases streptomycin can replace ethambutol. This initial phase of intensive treatment is followed by a consolidation phase. Drugs should be administered in the morning on an empty stomach one hour before meals. Treatment of latent tuberculosis (TB) infection is an important component of TB control programs. Preventive treatment can reduce the risk of developing active TB.

    An update on the current research and development of the treatment technologies, which utilize natural processes or passive components in wastewater treatment, is provided in this paper. The main focus is on wetland systems and their applications in wastewater treatment (as an advanced treatment unit or decentralized system), nutrient and pollutant removal (metals, industrial and emerging pollutants including pharmaceutical compounds). A summary of studies involving the effects of vegetation, wetland design and modeling, hybrid and innovative systems, storm water treatment and pathogen removal is also included. PMID:27620086

  16. Experimental treatments of endometriosis.

    2015-08-01

    Endometriosis is defined as the presence of endometrial gland and stroma outside the uterine cavity. It is an estrogen-dependent disease and is associated with chronic pelvic pain, dysmenorrhea, dyspareunia and infertility. The treatment of endometriosis is conservative or radical surgery, medical therapies or their combination. All currently used hormonally active treatments are effective in the treatment of endometriosis; however, the adverse effects of these hormonal treatments limit their long-term use. Moreover, recurrence rates are high after cessation of therapy, and the treatments have no benefit in endometriosis-associated infertility. Therefore, researchers are working on new treatment modalities with improved side effects, mainly focusing on the molecular targets involved in etiopathogenesis of endometriosis. Here we summarized these novel treatments modalities.

    We review recent developments in the acute and long-term treatment of bipolar disorder and identify promising future routes to therapeutic innovation. Overall, advances in drug treatment remain quite modest. Antipsychotic drugs are effective in the acute treatment of mania; their efficacy in the treatment of depression is variable with the clearest evidence for quetiapine. Despite their widespread use, considerable uncertainty and controversy remains about the use of antidepressant drugs in the management of depressive episodes. Lithium has the strongest evidence for long-term relapse prevention; the evidence for anticonvulsants such as divalproex and lamotrigine is less robust and there is much uncertainty about the longer term benefits of antipsychotics. Substantial progress has been made in the development and assessment of adjunctive psychosocial interventions. Long-term maintenance and possibly acute stabilisation of depression can be enhanced by the combination of psychosocial treatments with drugs. The development of future treatments should consider both the neurobiological and psychosocial mechanisms underlying the disorder. We should continue to repurpose treatments and to recognise the role of serendipity. We should also investigate optimum combinations of pharmacological and psychotherapeutic treatments at different stages of the illness. Clarification of the mechanisms by which different treatments affect sleep and circadian rhythms and their relation with daily mood fluctuations is likely to help with the treatment selection for individual patients. To be economically viable, existing psychotherapy protocols need to be made briefer and more efficient for improved scalability and sustainability in widespread implementation. PMID:23663953

  18. Treatment of social phobias.

    PubMed

    Agras, W S

    1990-10-01

    Social phobia, despite a prevalence in the general population of 1.5% denoting a common disorder, has been relatively neglected from the viewpoints of psychopathology and of treatment. Two subtypes of social phobia have been differentiated: specific (characterized by anxiety in one situation, e.g., public speaking) and generalized (characterized by anxiety in several social situations). The syndrome is frequently complicated by alcohol abuse or dependence. Among the treatment targets are symptoms of anxiety, avoidance behavior, negative cognitions concerning the reactions of others, and, less frequently, social skills deficits. Both pharmacologic and cognitive-behavioral treatments have been found effective in this disorder, and it seems likely that the two treatments will complement each other. The treatment literature is reviewed, and recommendations concerning a state-of-the-art treatment approach to both specific and generalized social phobia are made. Potential complications and limitations are discussed.

    Supraphysiological administration of anabolic androgenic steroids has been linked to increased blood pressure. The widely distributed amino acid taurine seems to be an effective depressor agent in drug-induced hypertension. The purpose of this study was to assess the impact of chronic high dose administration of nandrolone decanoate (DECA) and taurine on blood pressure in rats and to verify the potentially involved mechanisms. The study was conducted in 4 groups of 8 adult male Wistar rats, aged 14 weeks, treated for 12 weeks with: DECA (A group); vehicle (C group); taurine (T group), or with both drugs (AT group). Systolic blood pressure (SBP) was measured at the beginning of the study (SBP1), 2 (SBP2) and 3 months (SBP3) later. Plasma angiotensin-converting enzyme (ACE) activity and plasma end products of nitric oxide metabolism (NOx) were also determined. SBP3 and SBP2 were significantly increased compared to SBP1 only in the A group (P<0.002 for both). SBP2, SBP3 and ACE activity showed a statistically significant increase in the A vs C (P<0.005), andvs AT groups (P<0.05), while NOx was significantly decreased in the A and AT groups vs controls (P=0.01). ACE activity was strongly correlated with SBP3 in the A group (r=0.71, P=0.04). These findings suggest that oral supplementation of taurine may prevent the increase in SBP induced by DECA, an effect potentially mediated by angiotensin-converting enzyme.

    Increasingly accountable for the environmental quality and cost of managing their waste and process water streams, customers require more precise data about the constituents in their water. This has forced suppliers to unlock some of the secrets of water treatment. In the open exchange of information, users are trading in esoteric formulations for products that are more chemical efficient and environmentally benign. Factoring more prominently in the water treatment equation are service and supply. This paper reviews some of these simpler treatments.

They belong to three main classes, antihistamines, steroids and mast cell stabilizers. Since it is a relatively benign and also highly common disease, treatment options are limited by possible, even mild, side effects and by cost efficacy restriction. In the more severe forms of the condition, treatment efficacy remains unsatisfactory.

    Ankylosing spondylitis is a chronic, inflammatory, rheumatic disease that can reduce the quality of life and increase the risk of disability and mortality. It also causes direct and indirect economic losses due to health expenses and as a result of workforce loss. Management of this disease consists of pharmacological and nonpharmacological modalities. Until recently, pharmacological treatment options have been very limited. However, development of novel biological drugs revolutionized the management of this disease. The aim of this review article is to present an updated overview of the pharmacologic treatment of ankylosing spondylitis. Nonpharmacological treatment modalities including physiotherapy and exercise are only briefly mentioned and surgical treatment is not discussed.

    Eosinophilic esophagitis (EoE) is a relatively new entity with a significant amount of increased recognition over the last decade. The mainstay treatments of EoE are designed to eliminate the causative allergens or to reduce their effects on the esophageal mucosa. Common treatments include dietary modification, proton pump inhibitors, systemic and topical corticosteroids, and endoscopic treatments. As the pathogenesis of EoE is explored, new and novel treatments are being studied that target specific pathways and chemokines identified in as precipitating agents of EoE. This is a rapidly evolving field with significant ongoing research and clinical studies. Our review will therefore focus on current and novel treatment approaches to the disease.

    2005-07-01

    Remarkable therapeutic improvements have come forward recently for trigemino-autonomic cephalalgias. Attack treatment in cluster headache is based on sumatriptan and oxygen. Non-vasoconstrictive treatments are opening a new post-triptan era but are not yet applicable. Prophylactic treatment of cluster headache is based on verapamil and lithium. The efficacy of anti-epileptic drugs in cluster headache remains to be demonstrated. Surgical treatment aimed at the parasympathetic pathways and at the trigeminal nerve demonstrates a high rate of recurrence and adverse events and questions about the relevance of a "peripheral" target in cluster headache. The efficacy of continuous hypothalamic stimulation in patients with intractable headache constitutes a breakthrough, but must be demonstrated at a larger scale and the benefice/risk ratio must be carefully evaluated. Indomethacin still remains the gold standard in paroxysmal hemicrania treatment. Until recently SUNCT was considered an intractable condition. However there are some reports of complete relief with lamotrigine, topiramate and gabapentin.

    West syndrome is one of the most refractory epileptic syndromes in infancy, and many researchers have made great effort to find optimal treatment modalities for this syndrome. In this review, previous literature on optimal treatments of West syndrome and its refractory nature were briefly presented, followed by an introduction of recent publication of expert opinions from the US and Europe. An Asian expert opinion generated by a short questionnaire survey was then presented. It was shown that medically proven optimal treatment of West syndrome is not always the practical treatment of choice in Asian countries. Cost and geographical regions should also be taken into account in making practical choices for treatment of West syndrome. PMID:21196092

    Acute promyelocytic leukemia (APL) is characterized by coagulopathy, leukopenic presentation and sensitivity to anthracyclines, all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). For the last 25 years, APL has been treated with a combination of ATRA and chemotherapy for induction followed by consolidation and maintenance therapy. This general treatment approach has resulted in cure rates of 80–90%. ATO, originally approved in relapsed APL, has been incorporated into contemporary upfront treatment regimens with excellent response rates. Recent studies show that most patients with APL can be cured with ATRA and ATO alone, eliminating cytotoxic chemotherapy and resulting in superior outcomes compared to standard treatment. We will herein review historical treatment of APL, treatment considerations in specific patient populations, and therapeutic updates. PMID:24643310

    Nonpharmacological treatment of epilepsy includes surgery, vagal nerve stimulation, ketogenic diet, and other alternative/complementary therapies, e.g., yoga, Ayurveda, electroencephalography (EEG) biofeedback technique, aerobic exercise, music therapy, transcranial magnetic stimulation, acupuncture, and herbal remedies (traditional Chinese medicine). Alternative therapies, despite the term, should not be considered as an alternative to antiepileptic medication; they complement accepted drug treatment. Alternative therapies like yoga, through techniques that relax the body and mind, reduce stress, improve seizure control, and also improve quality of life. Ketogenic diet is a safe and effective treatment for intractable epilepsies; it has been recommended since 1921. The diet induces ketosis, which may control seizures. The most successful treatment of epilepsy is with modern antiepileptic drugs, which can achieve control of seizures in 70-80% cases. Patients opt for alternative therapies because they may be dissatisfied with antiepileptic drugs due to their unpleasant side effects, the long duration of treatment, failure to achieve control of seizures, cultural beliefs and, in the case of women, because they wish to get pregnant Surgical treatment may lead to physical and psychological sequelae and is an option only for a minority of patients. This article presents supportive evidence from randomized controlled trials done to assess the benefit of non-pharmacological treatment. PMID:22028523

    The most common fractures of the spine are associated with the thoracolumbar junction. The goals of treatment of thoracolumbar fracture are leading to early mobilization and rehabilitation by restoring mechanical stability of fracture and inducing neurologic recovery, thereby enabling patients to return to the workplace. However, it is still debatable about the treatment methods. Neurologic injury should be identified by thorough physical examination for motor and sensory nerve system in order to determine the appropriate treatment. The mechanical stability of fracture also should be evaluated by plain radiographs and computed tomography. In some cases, magnetic resonance imaging is required to evaluate soft tissue injury involving neurologic structure or posterior ligament complex. Based on these physical examinations and imaging studies, fracture stability is evaluated and it is determined whether to use the conservative or operative treatment. The development of instruments have led to more interests on the operative treatment which saves mobile segments without fusion and on instrumentation through minimal invasive approach in recent years. It is still controversial for the use of these treatments because there have not been verified evidences yet. However, the morbidity of patients can be decreased and good clinical and radiologic outcomes can be achieved if the recent operative treatments are used carefully considering the fracture pattern and the injury severity.

    This chapter aims to outline a flexible framework which the dental team can use to bring together key elements of information about their patients and their patients' teeth in order to plan appropriate, patient-centred, caries management based on the application of best current evidence and practice. This framework can be enabled by the use of the International Caries Detection and Assessment System (ICDAS) clinical visual scoring systems for caries detection and activity, but also needs additional information about lesions and the patient to plan and then monitor the effectiveness of personalized caries care. The treatment planning process has evolved from restorative treatment decisions being largely made during clinical assessment as an examination of wet teeth proceeds, with limited charting and a minor role for patient factors. Best practice now involves a comprehensive examination being made systematically of clean dry teeth using sharp eyes and blunt probes. The ICDAS-enabled framework provides for information to be collected at the tooth/surface level (clinical visual lesion detection, lesion detection aids and lesion activity assessment) and at the patient level (patient caries risk assessment, dentition and lesion history and patient behavioural assessment). This information is then synthesized to inform integrated, personalized treatment planning which involves the choice of appropriate treatment options (background level care, preventive treatment options, operative treatment options) and then recall, reassessment and monitoring. Examples of international moves towards using integrated, personalized treatment planning for caries control are given, drawing on experiences in the UK, the USA and from the ICDAS Committee.

    We define chronic migraine as that clinical situation in which migraine attacks appear 15 or more days per month. Until recently, and in spite of its negative impact, patients with chronic migraine were excluded of the clinical trials. This manuscript revises the current treatment of chronic migraine. The first step should include the avoidance of potential precipitating/aggravating factors for chronic migraine, mainly analgesic overuse and the treatment of comorbid disorders, such as anxiety and depression. The symptomatic treatment should be based on the use of nonsteroidal anti-inflammatory agents and triptans (in this case < 10 days per month). It is necessary to avoid the use of combined analgesics, opioids and ergotamine-containing medications. Preventive treatment includes a 'transitional' treatment with nonsteroidal anti-inflammatory agents or steroids, while preventive treatment exerts its actions. Even though those medications efficacious in episodic migraine prevention are used, the only drugs with demonstrated efficacy in the preventive treatment of chronic migraine are topiramate and pericranial infiltrations of Onabotulinumtoxin A.

    Acne is a common inflammatory skin disease which affects the pilosebaceous units of the skin. It can have severe psychological effects and can leave the patient with severe skin scarring. There are four well-recognized pathological factors responsible for acne which is also the target for acne therapy. In this review, different treatment options are discussed, including topical (i.e., retinoids, and antibiotics) and systemic (i.e., retinoids, antibiotics, and hormonal) treatments. Since the general public has been showing an increasing interest in more natural and generally safer treatment options, the use of complementary and alternative medicines (CAM) for treating acne was also discussed. The use of physical therapies such as comedone extraction, cryoslush therapy, cryotherapy, electrocauterization, intralesional corticosteroids and optical treatments are also mentioned. Acne has been extensively researched with regards to the disease mechanism as well as treatment options. However, due to the increasing resistance of Propionibacterium acnes towards the available antibiotics, there is a need for new treatment methods. Additionally, the lack of necessary evidence on the efficacy of CAM therapies makes it necessary for researchers to investigate these treatment options further. PMID:27529209

  7. Land Treatment Digital Library

    2009-01-01

    Across the country, public land managers make hundreds of decisions each year that influence landscapes and ecosystems within the lands they manage. Many of these decisions involve vegetation manipulations known as land treatments. Land treatments include activities such as removal or alteration of plant biomass, seeding burned areas, and herbicide applications. Data on these land treatments are usually stored at local offices, and gathering information across large spatial areas can be difficult. There is a need to centralize and store treatment data for Federal agencies involved in land treatments because these data are useful to land managers for policy and management and to scientists for developing sampling designs and studies. The Land Treatment Digital Library (LTDL) was created by the U.S. Geological Survey (USGS) to catalog information about land treatments on Federal lands in the western United States for all interested parties. The flexible framework of the library allows for the storage of a wide variety of data in different formats. The LTDL currently stores previously established land treatments or what often are called legacy data. The project was developed and has been refined based on feedback from partner agencies and stakeholders, with opportunity for the library holdings to expand as new information becomes available. The library contains data in text, tabular, spatial, and image formats. Specific examples include project plans and implementation reports, monitoring data, spatial data files from geographic information systems, digitized paper maps, and digital images of land treatments. The data are entered by USGS employees and are accessible through a searchable web site. The LTDL can be used to respond to information requests, conduct analyses and other forms of information syntheses, produce maps, and generate reports for DOI managers and scientists and other authorized users.

    Background The evaluation of research output, such as estimation of the proportion of treatment successes, is of ethical, scientific, and public importance but has rarely been evaluated systematically. We assessed how often experimental cancer treatments that undergo testing in randomized clinical trials (RCTs) result in discovery of successful new interventions. Methods We extracted data from all completed (published and unpublished) phase 3 RCTs conducted by the National Cancer Institute cooperative groups since their inception in 1955. Therapeutic successes were determined by (1) assessing the proportion of statistically significant trials favoring new or standard treatments, (2) determining the proportion of the trials in which new treatments were considered superior to standard treatments according to the original researchers, and (3) quantitatively synthesizing data for main clinical outcomes (overall and event-free survival). Results Data from 624 trials (781 randomized comparisons) involving 216 451 patients were analyzed. In all, 30% of trials had statistically significant results, of which new interventions were superior to established treatments in 80% of trials. The original researchers judged that the risk-benefit profile favored new treatments in 41% of comparisons (316 of 766). Hazard ratios for overall and event-free survival, available for 614 comparisons, were 0.95 (99% confidence interval [CI], 0.93-0.98) and 0.90 (99% CI, 0.87- 0.93), respectively, slightly favoring new treatments. Breakthrough interventions were discovered in 15% of trials. Conclusions Approximately 25% to 50% of new cancer treatments that reach the stage of assessment in RCTs will prove successful. The pattern of successes has become more stable over time. The results are consistent with the hypothesis that the ethical principle of equipoise defines limits of discoverability in clinical research and ultimately drives therapeutic advances in clinical medicine.

    Chronic pain may be considered a disease and its treatment a necessity. Neurosurgical treatment of chronic pain is justified in cases where conservative treatment is no longer effective or causes excessive side effects. The new percutaneous methods involve no stress, minimal risk and short hospitalization. Destructive neurosurgical procedures are mainly used for cancer pain, with the exception of trigeminal neuralgia. Non-destructive neurostimulating methods to control pain are well on the way to achieving their optimum clinical potential and preserve the integrity of the nervous system. PMID:7330647

Variation in temperature and times for both solution and aging were performed. Photomicrographs were made of the microstructure and volume fraction analysis of primary gamma-prime and aged gamma-prime precipitates were performed. The results of the heat treatment, cooling rate, and directional solidification experiments are discussed.

  11. Surgical treatment of osteomyelitis.

    PubMed

    Cierny, George

    2011-01-01

    Chronic osteomyelitis is refractory to nonsurgical treatment due to a resilient, infective nidus that harbors sessile, matrix-protected pathogens bound to substrate surfaces within the wound. Curative treatment mandates physical (surgical) removal of the biofilm colony, adjunctive use of antibiotics to eliminate residual phenotypes, and efforts to optimize the host response throughout therapy. Patient selection, therapeutic options, and the treatment format are determined by the Cierny/Mader staging system, while reconstruction is governed by the integrity/stability of the affected bone(s) and quality/quantity parameters of the soft-tissue envelope.

    Ross, E Victor

    2005-01-01

    Light-based treatments for acne are becoming increasingly commonplace in dermatology. This article reviews various light approaches in acne therapy. Methods are discussed from an anatomical and a functional perspective. The emphasis is on the practicality of treatment as well as the pros and cons of various devices. Also, a review of the recent literature is presented. The article is intended to give the reader a panoramic view of this still-young and developing area. Most likely, light-based acne treatment will receive more popularity as dermatologists learn how to integrate this type of therapy within the context of more established drug agents. PMID:16229726

    Trushkowsky, Richard D; Oquendo, Anabella

    2011-07-01

    Dentinal hypersensitivity is exemplified by brief, sharp, well-localized pain in response to thermal, evaporative, tactile, osmotic, or chemical stimuli that cannot be ascribed to any other form of dental defect or pathology. Pulpal pain is usually more prolonged, dull, aching, and poorly localized and lasts longer than the applied stimulus. Up to 30% of adults have dentinal hypersensitivity at some time. Current techniques for treatment may be only transient in nature and results are not always predictable. Two methods of treatment of dentin hypersensitivity are tubular occlusion and blockage of nerve activity. A differential diagnosis needs to be accomplished before any treatment. PMID:21726693

    SUMMARY The objective of this article was to perform a narrative review regarding the treatment of myofascial pain syndrome and to provide clinicians with treatment recommendations. This paper reviews the efficacy of various myofascial pain syndrome treatment modalities, including pharmacological therapy, injection-based therapies and physical therapy interventions. Outcomes evaluated included pain (visual analog scale), pain pressure threshold and range of motion. The evidence found significant benefit with multiple treatments, including diclofenac patch, thiocolchicoside and lidocaine patches. Trigger point injections, ischemic compression therapy, transcutaneous electrical nerve stimulation, spray and stretch, and myofascial release were also efficacious. The authors recommend focusing on treating underlying pathologies, including spinal conditions, postural abnormalities and underlying behavioral issues. To achieve maximum pain reduction and improve function, we recommend physicians approach myofascial pain syndrome with a multimodal plan, which includes a combination of pharmacologic therapies, various physical therapeutic modalities and injection therapies.

    2013-01-01

    The management of recurrent furunculosis is difficult, and often disappointing. We present the case of a 23-year-old female patient suffering from recurrent furunculosis. The furunculosis persisted after treatment with mupirocin nasal ointment, chlorhexidine soap and instructions for washing clothes, towels and bed sheets for a period of 7 days. Treatment with low-dose clindamycin for three months ultimately proved successful. We propose a structural approach for recurrent furunculosis in which extensive history-taking is followed by appropriate tests. Before prescribing an oral antibiotic (preferably low-dose clindamycin or a macrolide for 3 months), the patient should use an antimicrobial nasal ointment and soap and follow hygienic instructions as mentioned above. Members of the household who also have signs of the infection should be treated. Hygienic education is an essential component of treatment. We believe that this approach will lead to a treatment that is more effective and efficient.

    The results of an experimental research program to investigate the potential of improving compressor stall margin by the application of hub treatment are presented. Extensive tuft probing showed that the two-stage, 0.5 radius ratio compressor selected for the test was indeed hub critical. Circumferential groove and baffled wide blade angle slot hub treatments under the stators were tested. Performance measurements were made with total and static pressure probes, wall static pressure taps, flow angle measuring instrumentation and hot film anemometers. Stator hub treatment was not found to be effective in improving compressor stall margin by delaying the point of onset of rotating stall or in modifying compressor performance for any of the configurations tested. Extensive regions of separated flow were observed on the suction surface of the stators near the hub. However, the treatment did not delay the point where flow separation in the stator hub region becomes apparent.

    2013-03-01

    Decades of practice in psychiatriy and hundreds of clinical trials have demonstrated the efficacy of antipsychotics on symptoms of schizophrenia. Recently, the knowledge acquired from non-interventional studies have supplemented the information needed in daily practice by raising the issue of efficiency by incorporating not only the effectiveness and safety of treatment but also its acceptability by the patient. Adherence to antipsychotic treatment has become the key issue of the prognosis. The pharmacological management of patients with an acute episode of schizophrenia requires rapid therapeutic decisions to treat a patient who is likely to be sometimes unhelpful and agitated. The choice of treatment will have a significant impact on the prevention of psychotic relapses, on the overall prognosis and on the quality of life of the patient. In many countries of the recommendations and treatment algorithms for the management of acute psychosis were distributed, considering factors specific to the patient and his environment, his mental characteristics and local care setting.

    A thermal treatment wall emplaced to perform in-situ destruction of contaminants in groundwater. Thermal destruction of specific contaminants occurs by hydrous pyrolysis/oxidation at temperatures achievable by existing thermal remediation techniques (electrical heating or steam injection) in the presence of oxygen or soil mineral oxidants, such as MnO.sub.2. The thermal treatment wall can be installed in a variety of configurations depending on the specific objectives, and can be used for groundwater cleanup, wherein in-situ destruction of contaminants is carried out rather than extracting contaminated fluids to the surface, where they are to be cleaned. In addition, the thermal treatment wall can be used for both plume interdiction and near-wellhead in-situ groundwater treatment. Thus, this technique can be utilized for a variety of groundwater contamination problems.

    1997-03-01

    In developing their Site Treatment Plans (STPs), many of the Department of Energy installations identified some form of portable treatment, to facilitate compliant disposition of select mixed low-level wastestreams. The Environmental Management Office of Science and Technology requested that a systems study be performed to better define the potential role of portable treatment with respect to mixed low-level waste, highlight obstacles to implementation, and identify opportunities for future research and development emphasis. The study was performed by first establishing a representative set of mixed waste, then formulating portable treatment system concepts to meet the required processing needs for these wastes. The portable systems that were conceptualized were evaluated and compared to a fixed centralized treatment alternative. The system evaluations include a life-cycle cost analysis and an assessment of regulatory, institutional, and technical issues associated with the potential use of portable systems. The results of this study show that when all costs are included, there are no significant cost differences between portable systems and fixed systems. However, it is also emphasized that many uncertainties exist that could impact the cost of implementing portable treatment systems. Portable treatment could be made more attractive through private sector implementation, although there is little economic incentive for a commercial vendor to develop small, specialized treatment capabilities with limited applicability. Alternatively, there may also be valid reasons why fixed units cannot be used for some problematic wastestreams. In any event, there are some site-specific problems that still need to be addressed, and there may be some opportunity for research and development to make a positive impact in these areas.

    2004-07-01

    This presentation is designed as a brief overview of laser use in gynecology, for non-medical researchers involved in development of new laser techniques. The literature of the past decade is reviewed. Differences in penetration, absorption, and suitable delivery media for the beams dictate clinical application. The use of CO2 laser in the treatment of uterine cervical intraepithelial lesions is well established and indications as well as techniques have not changed over 30 years. The Cochrane Systematic Review from 2000 suggests no obviously superior technique. CO2 laser ablation of the vagina is also established as a safe treatment modality for VAIN. CO2 laser permits treatment of lesions with excellent cosmetic and functional results. The treatment of heavy menstrual bleeding by destruction of the endometrial lining using various techniques has been the subject of a 2002 Cochran Database Review. Among the compared treatment modalities are newer and modified laser techniques. Conclusion by reviewers is that outcomes and complication profiles of newer techniques compare favorably with the gold standard of endometrial resection. The ELITT diode laser system is one of the new successful additions. CO2 laser is also the dominant laser type used with laparoscopy for ablation of endometriotic implants. Myoma coagulation or myolysis with Nd:Yag laser through the laparoscope or hysteroscope is a conservative treatment option. Even MRI guided percutaneous approaches have been described. No long-term data are available.

  6. Dietary treatments of obesity.

    PubMed

    Bennett, W

    1987-01-01

    Dietary treatment of obesity is based on one or another of two premises: that the obese eat too much or that they eat the wrong things. The first is a tautology lacking explanatory power. The second is a meaningful and promising hypothesis but has yet to be effectively applied. At present, virtually all outpatient treatments of obesity, including behavior modification, are based on the first premise and consist of strategies for reducing the subject's caloric intake. Most such interventions produce short-term weight loss. Regain after the end of treatment remains the usual outcome. A survey of studies published in the period 1977-1986 and reporting on dietary or behavioral treatment of obesity reveals that the maximum percentage of body weight lost is, on average, 8.5 percent--no different from the value, 8.9%, in similar studies from 1966-1976, as reviewed by Wing and Jeffery. The principal determinant of success in such programs appears to be the intake weight of the subjects: the higher the intake weight, the more successful the intervention will appear to be. The goals and research methods of studies on dietary treatments for obesity are overdue for ethical as well as scientific reevaluation. The same may be said for the numerous programs providing such treatment outside the context of research.

  7. Treatment options for hyperhidrosis.

    PubMed

    Walling, Hobart W; Swick, Brian L

    2011-10-01

    Hyperhidrosis is a disorder of excessive sweating beyond what is expected for thermoregulatory needs and environmental conditions. Primary hyperhidrosis has an estimated prevalence of nearly 3% and is associated with significant medical and psychosocial consequences. Most cases of hyperhidrosis involve areas of high eccrine density, particularly the axillae, palms, and soles, and less often the craniofacial area. Multiple therapies are available for the treatment of hyperhidrosis. Options include topical medications (most commonly aluminum chloride), iontophoresis, botulinum toxin injections, systemic medications (including glycopyrrolate and clonidine), and surgery (most commonly endoscopic thoracic sympathectomy [ETS]). The purpose of this article is to comprehensively review the literature on the subject, with a focus on new and emerging treatment options. Updated therapeutic algorithms are proposed for each commonly affected anatomic site, with practical procedural guidelines. For axillary and palmoplantar hyperhidrosis, topical treatment is recommended as first-line treatment. For axillary hyperhidrosis, botulinum toxin injections are recommended as second-line treatment, oral medications as third-line treatment, local surgery as fourth-line treatment, and ETS as fifth-line treatment. For palmar and plantar hyperhidrosis, we consider a trial of oral medications (glycopyrrolate 1-2 mg once or twice daily preferred to clonidine 0.1 mg twice daily) as second-line therapy due to the low cost, convenience, and emerging literature supporting their excellent safety and reasonable efficacy. Iontophoresis is considered third-line therapy for palmoplantar hyperhidrosis; efficacy is high although so are the initial levels of cost and inconvenience. Botulinum toxin injections are considered fourth-line treatment for palmoplantar hyperhidrosis; efficacy is high though the treatment remains expensive, must be repeated every 3-6 months, and is associated with pain and

    2014-12-01

    A positive mycological examination is required before discussion of treatment of onychomycosis. Onychomycosis is most commonly due to dermatophytes in association with tinea pedis and/or tinea manuum. It is a catched infection. Candida onychomycosis is a rare opportunistic infection and onychomycosis due to non-dermatophytic moulds is very rare as a "chance mishap". The treatment of dermatophyte onychomycosis takes each infected part of the nail into account. Topical antifungal agents should be reserved for mild to moderate onychomycosis. Systemic antifungal agents are required to severe onychomycosis. In all cases, removal of infected nail parts is useful to facilitate the penetration of antifungal drugs and eradication of reinfection sites may be done to prevent recurrences and relapses. In primary, Candida onychomycosis treatment with topical antifungal drugs may be effective but in case of treatment failure, a systemic therapy is required. Suppression predisposing factors is useful. The treatment of non-dermatophytic moulds onychomycosis is still a challenge. Except Neoscytalidium spp., which mimic a dermatophytosis, non-dermatophytic moulds may be isolated from dystrophic nails and it is always difficult to specify their role as a primary pathogen or as a colonizer of nails. The available topical and systemic antifungal drugs are not effective against these non-dermatophytic moulds except itraconazole for onychomycosis due to Aspergillus spp. New therapy such as light and laser therapy are in evaluation.

  10. [Pharmacological treatment of hyperinflation].

    PubMed

    Devillier, P; Roche, N

    2009-06-01

    Introduction Lung hyperinflation leads to breathlessness, limitation in exercise capacity and tolerance, and impaired quality of life. Thus, it is important to target this key and characteristic feature of COPD. Current knowledge Available pharmacological approaches rely mainly on bronchodilators, in particular beta2 agonists and anticholinergic agents. These treatments act through the reduction of expiratory airflow limitation. However, changes in classical indices of airflow obstruction do not accurately predict effects on hyperinflation and symptoms. The decrease in operating lung volumes (as reflected by inspiratory capacity or functional residual capacity) at rest and during exercise is one of the mechanisms by which these treatments improve quality of life and maybe also decrease the impact of exacerbations. The effect of beta2 agonists on hyperinflation might be amplified by concurrent treatment with inhaled corticosteroids. Perspectives The effect of new treatments targeting airways inflammation on hyperinflation remains to be explored. Conclusions Measuring the reduction in the degree of lung hyperinflation allows a better understanding of the symptomatic effect of COPD pharmacological treatments.

    1999-08-01

    The U.S. Department of Energy (DOE) is responsible for the final disposition of legacy spent nuclear fuel (SNF). As a response, DOE's National Spent Nuclear Fuel Program (NSNFP) has been given the responsibility for the disposition of DOE -owned SNF. Many treatment technologies have been identified to treat some forms of SNF so that the resulting treated product is acceptable by the disposition site. One of these promising treatment processes is the electrometallurgical treatment (EMT) currently in development; a second is an Acid Wash Decladding process. The NSNFP has been tasked with identifying possible strategies for the deployment of these treatment processes in the event that the treatment path is deemed necessary. To support the siting studies of these strategies, economic evaluations are being performed to identify the least-cost deployment path. This model (tool) was developed to consider the full scope of costs, technical feasibility, process material disposition, and schedule attributes over the life of each deployment alternative. Using standard personal computer (PC) software, the model was developed as a comprehensive technology economic assessment tool using a Life-Cycle Cost (LCC) analysis methodology. Model development was planned as a systematic, iterative process of identifying and bounding the required activities to dispose of SNF. To support the evaluation process, activities are decomposed into lower level, easier to estimate activities. Sensitivity studies can then be performed on these activities, defining cost issues and testing results against the originally stated problem.

    2012-07-01

    The history of the development of generic phytosanitary irradiation (PI) treatments is discussed beginning with its initial proposal in 1986. Generic PI treatments in use today are 150 Gy for all hosts of Tephritidae, 250 Gy for all arthropods on mango and papaya shipped from Australia to New Zealand, 300 Gy for all arthropods on mango shipped from Australia to Malaysia, 350 Gy for all arthropods on lychee shipped from Australia to New Zealand and 400 Gy for all hosts of insects other than pupae and adult Lepidoptera shipped to the United States. Efforts to develop additional generic PI treatments and reduce the dose for the 400 Gy treatment are ongoing with a broad based 5-year, 12-nation cooperative research project coordinated by the joint Food and Agricultural Organization/International Atomic Energy Agency Program on Nuclear Techniques in Food and Agriculture. Key groups identified for further development of generic PI treatments are Lepidoptera (eggs and larvae), mealybugs and scale insects. A dose of 250 Gy may suffice for these three groups plus others, such as thrips, weevils and whiteflies.

  14. [Cryptorchidism: diagnosis and treatment].

    PubMed

    Longui, Carlos Alberto

    2005-02-01

    Cryptorchidism corresponds to the extra-scrotal position of the testis, and can be found in 3% of the term newborns and 0.5 to 1.0% of adults. It is usually an isolated clinical feature, but in around 10% of the cases can be associated to hypothalamic-pituitary dysfunction and genetic or embryonic disorders. The presence of additional genital abnormalities, such as hypospadia or micropenis, increases the probability of the diagnosis of an intersex condition. Detailed description of the testicular anatomic position is essential to adequate diagnosis, treatment and prognostic evaluation. The diagnosis of cryptorchidism is made by clinical examination. The complementary exams, such as image analysis, add limited information on the diagnosis. Gonadotropins and testicular hormones measurement can be useful if the hypothalamic-pituitary-gonadal axis is activated, as observed during the first 6 months of life or during puberty. Clinical treatment is indicated in patients with retained testis or in severely retractile testis. In these cases, human chorionic gonadotropin is employed at a dose of 50 IU/kg/week for 6 consecutive weeks. Clinical treatment cannot be used in cases of confirmed inguinal hernia, varicocele or spermatic cord cysts. Surgical correction is indicated after failure of clinical treatment or for ectopic testes. The long-term prognosis of cryptorchidism seems to be related to the precocity of the therapy. Therefore, recognition and treatment of cryptorchid testes should be done during the first 2 years of life, potentially improving the risks of infertility and gonadal neoplasia.

All orthopedists know about osteoporosis because of its most deleterious effect: osteoporotic fracture. Osteoporosis without fractures does not arouse suspicion because this is a pathological condition with a nonspecific clinical profile. Osteoporotic fractures have an economic cost (from treatment), a social cost (from its sequelae) and a medical cost (from deaths). Many fractures could be avoided through diagnosing osteoporosis prior to the first fracture and thus many temporary and permanent disabilities could be avoided and many lives saved. Awareness of the risk factors for osteoporosis raises suspicions and bone densitometry aids in diagnosis. Treatment should be based on the physiopathology of the disease. Hence, for prevention or treatment of osteoporosis, the activity of osteoclasts should be diminished or the activity of osteoblasts should be increased, or both. Treatment that reduces the incidence of fractures by improving the bone geometry and microarchitecture would be ideal. Newly formed bone tissue needs to have good cell and matrix quality, normal mineralization, a good ratio between mineralized (mechanically resistant) and non-mineralized (flexible) bone, and no accumulated damage. The ideal treatment should have a positive remodeling rate and fast and long-lasting therapeutic effects. Such effects need to be easily detectable. They need to be safe. PMID:27022545

  16. Preventive Migraine Treatment

    PubMed Central

    Silberstein, Stephen D.

    2015-01-01

    Purpose of Review: This article reviews the evidence base for the preventive treatment of migraine. Recent Findings: Evidence-based guidelines for the preventive treatment of migraine have recently been published by the American Academy of Neurology (AAN) and the Canadian Headache Society (CHS), providing valuable guidance for clinicians. Strong evidence exists to support the use of metoprolol, timolol, propranolol, divalproex sodium, sodium valproate, and topiramate for migraine prevention, according to the AAN. Based on best available evidence, adverse event profile, and expert consensus, topiramate, propranolol, nadolol, metoprolol, amitriptyline, gabapentin, candesartan, Petasites (butterbur), riboflavin, coenzyme Q10, and magnesium citrate received a strong recommendation for use from the CHS. Summary: Migraine preventive drug treatments are underutilized in clinical practice. Principles of preventive treatment are important to improve compliance, minimize side effects, and improve patient outcomes. Choice of preventive treatment of migraine should be based on the presence of comorbid and coexistent illness, patient preference, reproductive potential and planning, and best available evidence.

  17. Treatment of Radiation Injury

    PubMed Central

    Akita, Sadanori

    2014-01-01

    Significance: Radiation exposure as a result of radiation treatment, accident, or terrorism may cause serious problems such as deficiency due to necrosis or loss of function, fibrosis, or intractable ulcers in the tissues and organs. When the skin, bone, oral mucous membrane, guts, or salivary glands are damaged by ionizing radiation, the management and treatment are very lengthy and difficult. Critical Issues: In severe and irreversible injuries, surgery remains the mainstay of treatment. Several surgical procedures, such as debridement, skin grafting, and local and free-vascularized flaps, are widely used. Recent Advances: In specific cases of major morbidity or in high-risk patients, a newly developed therapy using a patient's own stem cells is safe and effective. Adipose tissue, normally a rich source of mesenchymal stem cells, which are similar to those from the bone marrow, can be harvested, since the procedure is easy, and abundant tissue can be obtained with minimal invasiveness. Future Directions: Based on the molecular basis of radiation injuries, several prospective treatments are under development. Single-nucleotide polymorphisms focus on an individual's sensitivity to radiation in radiogenomics, and the pathology of radiation fibrosis or the effect of radiation on wound healing is being studied and will lead to new insight into the treatment of radiation injuries. Protectors and mitigators are being actively investigated in terms of the timing of administration or dose. PMID:24761339

  18. Surgical treatment of constipation.

    PubMed

    2004-01-01

    Constipation is a common symptom in clinical practice. Definition of constipation includes abnormal bowel frequency, difficulty during defecation and abnormal stool consistency. There are many classifications of constipation based on constipation etiology (constipation in healthy people caused by life style, constipation as a symptom of digestive tract diseases, secondary constipation in the course of systemic disorders or associated with drugs) and/or constipation mechanisms (functional, mechanical). The numerous disorders leading to constipation make often diagnostic management difficult and complicated. Treatment of constipation includes dietary and behavioral approaches, pharmacologic therapy and in selected patient surgical treatment. Surgical treatment is recommended in young patients with severe slow transit constipation refractory to conservative treatment. Confirmation of indication to surgical treatment requires studies of colonic and anorectal function (colonic transit studies, anorectal manometry, studies of defecation). Preferred surgical technique is colectomy with ileorectal anastomosis. Authors reported good results and patient satisfaction in 50-100 percent of cases. Postoperative complications include intestinal obstruction, abdominal pain, flatulence, diarrhea. PMID:15631313

    Recently, the treatment strategy for pediatric epilepsy has been dramatically changed in Japan, because of the approval of new-generation antiepileptic drugs. Since 2006, a total of 6 new antiepileptic drugs, including gabapentin (GBP; adults/pediatric patients: 2006/2011 [year of approval]), topiramate (TPM; 2007/2013), lamotrigine (LTG; 2008/2008), levetiracetam (LEV; 2010/2013), stiripentol (STP; 2012/2012), and rufinamide (RUF; 2013/2013), have been introduced. Thus far, valproate (VPA) and carbamazepine (CBZ) have been first indicated for "generalized" epilepsy and "focal" epilepsy syndromes/types, respectively, in Japan. However, the approval of these new drugs could allow us to choose more effective and less toxic ones at an early stage of treatment. In this chapter, we describe the latest domestic and foreign guidelines for the treatment of pediatric epilepsy. PMID:24912285

    2006-01-01

    Idiopathic inflammatory myopathies, notably polymyositis and dermatomyositis are comparatively uncommon diseases and few randomised, double blind placebo controlled trials have been done. Final validation of measures to assess outcome and response to treatment is awaited. Corticosteroids are an effective initial treatment, although rarely tested in randomised controlled trials. Unfortunately, not all patients respond to them and many develop undesirable side effects. There is thus a need for second line agents notably immunosuppressives or intravenous immunoglobulin. There are no defined guidelines or best treatment protocols agreed internationally and so the medical approach must be individualised, based on the severity of clinical presentation, disease duration, presence of extramuscular features, and prior therapy and contraindications to particular agents. There is still a significant percentage of non‐responders (around 25%) and clinical relapses. Novel therapeutic approaches are now directed towards cytokine modulation and the use of monoclonal antibodies targeting B and T cells. PMID:16822917

    Cellulite is a multifactorial etiology ailment. It changes the skin topography by the formation of the skin surface's appearance, changes described as "orange peel". This prob- lem concerns 85-98% of women, and for them it is one of the most intolerable aesthetic imperfections. In the past few years the interest of scientists in this problem has clearly increased. Several theories on the pathophysiology of cel- lulite have been produced A number of different thera- peutic regimens have been developed using modern tech- nology. However, despite the many treatment options for cellulite, it is extremely important that patients should be aware that only multidirectional treatment can bring sat- isfactory results. The aim of this review was to describe the causes of cellulite, and its prevention and treatment.

  8. The Treatment of Melioidosis

    PubMed Central

    Inglis, Timothy J.J.

    2010-01-01

    Melioidosis is a complex bacterial infection, treatment of which combines the urgency of treating rapidly fatal Gram negative septicaemia with the need for eradication of long-term persistent disease in pulmonary, soft tissue, skeletal and other organ systems. Incremental improvements in treatment have been made as a result of multicentre collaboration across the main endemic region of Southeast Asia and northern Australia. There is an emerging consensus on the three main patterns of antimicrobial chemotherapy; initial (Phase 1) treatment, subsequent eradication (Phase 2) therapy and most recently post-exposure (Phase 0) prophylaxis. The combination of agents used, duration of therapy and need for adjunct modalities depends on the type, severity and antimicrobial susceptibility of infection. New antibiotic and adjunct therapies are at an investigational stage but on currently available data are unlikely to make a significant impact on this potentially fatal infection. PMID:27713302

    Creativity can be defined as the ability to understand, develop, and express, in a systematic fashion, novel orderly relationships. It is sometimes difficult to separate cognitive skills requisite for the creative process from the drive that generates unique new ideas and associations. Epilepsy itself may affect the creative process. The treatment of epilepsy and its comorbidities, by altering or disrupting the same neural networks through antiseizure drugs (ASDs), treatment of epilepsy comorbidities, ablative surgery, or neurostimulation may also affect creativity. In this review, we discuss the potential mechanisms by which treatment can influence the creative process and review the literature on the consequences of therapy on different aspects of creativity in people with epilepsy. This article is part of a Special Issue entitled "Epilepsy, Art, and Creativity".

  11. Treatment of delinquents.

    1992-01-01

    The medical role in the treatment of delinquency is a limited one. There is conflicting evidence as to whether treatment aims should be directed towards the individual, to the family, the institution, or the therapist. Nevertheless there seems to be a consensus of opinion that short term, focused therapies aimed at improving educational, vocational and social skills, possibly from a preschool age, are the most effective. Any treatment gains achieved while in residential care appear to be short lived. It therefore seems that this should be reserved for those individuals who commit repeated, violent crimes and for those from very damaging family backgrounds who repeatedly abscond or absent themselves from community based programmes.

  12. Treatment of Lyme borreliosis

    2009-01-01

    Borrelia burgdorferi sensu lato is the causative agent of Lyme borreliosis in humans. This inflammatory disease can affect the skin, the peripheral and central nervous system, the musculoskeletal and cardiovascular system and rarely the eyes. Early stages are directly associated with viable bacteria at the site of inflammation. The pathogen-host interaction is complex and has been elucidated only in part. B. burgdorferi is highly susceptible to antibiotic treatment and the majority of patients profit from this treatment. Some patients develop chronic persistent disease despite repeated antibiotics. Whether this is a sequel of pathogen persistence or a status of chronic auto-inflammation, auto-immunity or a form of fibromyalgia is highly debated. Since vaccination is not available, prevention of a tick bite or chemoprophylaxis is important. If the infection is manifest, then treatment strategies should target not only the pathogen by using antibiotics but also the chronic inflammation by using anti-inflammatory drugs. PMID:20067594

    2012-01-01

    Premature ejaculation is the most common sexual dysfunction in men. Its prevalence rate in Europe and in United States is estimated to be between 20% and 30%. The diagnosis of premature ejaculation is based on three main criteria: increased intravaginal ejaculatory latency time (IELT), lack of control over ejaculation and interpersonal psychological disturbances. Premature ejaculation is classified as lifelong (primary) or acquired (secondary) and might be facilitated by chronic prostatitis, diabetes mellitus, hyperthyroidism, obesity. The exact etiology of the disease remains unclear, although 5-HT (5-hydroxytryptamine) receptors are known to have a significant role. The use of SSRIs (selective serotonine reuptake inhibitors) is old and efficient form of therapy for premature ejaculation. Other drugs like tramadol, clomipramine, local anaesthetics and PDE-5 (phosphodiesterase 5) inhibitors also have some efficacy in the treatment of premature ejaculation. To minimize adverse effects the "on demand" therapy is preferred to the daily treatment. Simple questionnaires for patients are used to assess treatment effects. PMID:22827115

    Synopsis The dystonias are a group of disorders characterized by excessive involuntary muscle contractions leading to abnormal postures and/or repetitive movements. There are many different clinical manifestations and many different causes. A careful assessment of the clinical manifestations is helpful for identifying syndromic patterns that focus diagnostic testing on potential causes. If a cause can be identified, specific etiology-based treatments may be available. However, in the majority of cases, a specific cause cannot be identified, and treatments are based on symptoms. Treatment options include counseling and education, oral medications, botulinum toxin injections, and several surgical procedures. A substantial reduction in symptoms and improved quality of life can be achieved in the majority of patients by combining these various options. PMID:25432724

    The excess consumption of alcohol is associated with alcoholic liver diseases (ALD). ALD is a major healthcare problem, personal and social burden, and significant reason for economic loss worldwide. The ALD spectrum includes alcoholic fatty liver, alcoholic hepatitis, cirrhosis, and the development of hepatocellular carcinoma. The diagnosis of ALD is based on a combination of clinical features, including a history of significant alcohol intake, evidence of liver disease, and laboratory findings. Abstinence is the most important treatment for ALD and the treatment plan varies according to the stage of the disease. Various treatments including abstinence, nutritional therapy, pharmacological therapy, psychotherapy, and surgery are currently available. For severe alcoholic hepatitis, corticosteroid or pentoxifylline are recommended based on the guidelines. In addition, new therapeutic targets are being under investigation. PMID:25278689

    Athletes usually complain of an ongoing or chronic pain over the Achilles tendon, but recently even non-athletes are experiencing the same kind of pain which affects their daily activities. Achilles tendinosis refers to a degenerative process of the tendon without histologic or clinical signs of intratendinous inflammation. Treatment is based on whether to stimulate or prevent neovascularization. Thus, until now, there is no consensus as to the best treatment for this condition. This paper aims to review the common ways of treating this condition from the conservative to the surgical options. PMID:25729512

    Enuresis is a common pediatric problem that creates a lot of stress for both the child and his/her family. Unfortunately, many of these patients do not seek medical attention for evaluation and treatment. It is important in the care of the child with enuresis to understand the definitions of the disorder, routinely ask about bowel and bladder habits, clarify the nature of the wetting (daytime, nighttime, or both) in the child, and perform a thorough history and physical examination. Laboratory studies are often minimal. Treatment (behavioral or medicinal) is dependent on the type of enuresis present, and patient compliance. Successful management of enuresis has benefits to both the child and family.

    Treatment of psychostimulant addiction has been a major, and not fully met, challenge. For opioid addiction, there is strong evidence for the effectiveness of several medications. For psychostimulants, there is no corresponding form of agonist maintenance that has met criteria for regulatory approval or generally accepted use. Stimulant-use disorders remain prevalent and can result in both short-term and long-term adverse consequences. The mainstay of treatment remains behavioral interventions. In this paper, we discuss those interventions and some promising candidates in the search for pharmacological interventions. PMID:24727297

    Fragility fractures typically occur in elderly patients related principally to osteoporosis. A significative percentage of these fractures have to be treated surgically but comorbilities are often present, and need to be grossly stabilized before surgery. However, there is for these fractures a high rate of morbidity and mortality at short-term. Moreover, patients affected by a fragility fracture are at risk for another fragility fracture later in life. The Authors present an overview of the main patterns of proximal femoral fractures, underlining the peculiar features and choices of surgical treatment, and relating to specific indications and results of each treatment.

    Although treatment-resistant schizophrenia (TRS) was described 50 years ago and has a gold standard treatment with clozapine based on well-defined criteria, there is still a matter of great interest and controversy. In terms of the underlying mechanisms of the development of TRS, progress has been made for the elucidation of the neurochemical mechanisms. Structural neuroimaging studies have shown that patients with TRS have significant reduction of the prefrontal cortex volume when compared with non- TRS.

    Myofascial pain syndrome (MPS) is a regional pain disorder caused by taut bands of muscle fibers in skeletal muscles called myofascial trigger points. MPS is a common disorder, often diagnosed and treated by physiatrists. Treatment strategies for MPS include exercises, patient education, and trigger point injection. Pharmacologic interventions are also common, and a variety of analgesics, antiinflammatories, antidepressants, and other medications are used in clinical practice. This review explores the various treatment options for MPS, including those therapies that target myofascial trigger points and common secondary symptoms.

    The range of treatments for hay fever available to the general practitioner has changed considerably in recent years. New antihistamines have addressed the problem of sedation and moved towards one daily dose; nasally applied corticosteroids avoid the need for systemic steroid therapy and its potential adverse effect; and regulatory decisions have set a trend away from immunotherapy in general practice. However, knowledge about the mechanism of action of immunotherapy is increasing and new developments with improved safety profiles include allergen polymers, allergoids, oral immunotherapy and nasal immunotherapy. Choice of treatment depends, as always, on the individual circumstances of the patient and his or her disease. PMID:2556545

    2011-01-01

    BACKGROUND: The increasing incidence of obesity and overweight among children and adolescents will be reflected by the imminent increase in the number of obese patients who require more definitive methods of treatment. There is great interest in new, safe, simple, nonsurgical procedures for weight loss. OBJECTIVE: To provide an overview of new endoscopic methods for the treatment of obesity. METHODS: An English-language literature search on endoscopic interventions, endoscopically placed devices and patient safety was performed in the MEDLINE and Cochrane Library databases. RESULTS: The literature search yielded the following weight loss methods: space-occupying devices (widely used), gastric capacity reduction, modifying gastric motor function and malabsorptive procedures. A commercially available intragastric balloon was the most commonly used device for weight loss. In specific subgroups of patients, it improved quality of life, decreased comorbidities and served as a bridge to surgery. More evidence regarding the potential benefits and safety of other commercially available intragastric balloons is needed to clarify whether they are superior to the most commonly used one. Moreover, early experiences with transoral gastroplasty, the duodenaljejunal bypass sleeve and an adjustable, totally implantable intragastric prosthesis, indicate that they may be viable options for obesity treatment. Other agents, such as botulinum toxin and a device known as the ‘butterfly’, are currently at the experimental stage. CONCLUSION: New endoscopic methods for weight loss may be valuable in the treatment of obesity; however, more clinical experience and technical improvements are necessary before implementing their widespread use.

  17. Groundwater treatment technology

    SciTech Connect

    Bazzazieh, N.

    1996-12-01

    When considering technologies for the common pump-and-treat scenario, identifying and characterizing the contaminant source area are the keys to successful operation. Under this scenario, groundwater is extracted from the subsurface, treated in an above-ground system, and returned to an aquifer or discharged to a publicly owned treatment works or surface water. Such a system also may contain a plume, or fixed concentration of contaminants. A sound hydrogeological assessment of the site and the contaminant plume provides a good estimate of cleanup time and of progress as treatment proceeds. In situ alternatives also can be considered for groundwater remediation. The combination of in situ and pump-and-treat technologies may result in considerable savings under some site conditions. Before evaluating technologies, an engineer needs to identify the organic and inorganic constituents at a site and study how effectively they can be treated by the proposed technologies. Such an evaluation should consider each technology`s capacity to handle maximum contaminant concentrations at the required maximum pumping rates. The three groundwater treatment technologies discussed here are carbon adsorption, air stripping, and biological treatment.

    1999-10-20

    Dietetic treatment of Crohn's disease has the objective to calm down the gut either by a polymeric or elemental diet. In superacute conditions also total parenteral nutrition can be used. In the quiescent stage the patient must have an adequate energy intake and a low-residue (low-fibre) diet. As to medication, sulfasalazine which has some side-effects is abandoned and 5-ASA (5-aminosalicylic acid) preparations are used, either by the oral route or in enemas, while 4-ASA is little used in this country and is known as PAS. The administration of corticoids which also have side-effects will be abandoned in favour of so-called rapidly metabolized corticoids (Tixocortol pivalate, beclomethasone, budenoside and fluticasone) by the oral route and in enemas and foams. As antimicrobial treatment ciprofloxacine is used combined with metronidazole. As to immunosuppressive drugs azathioprine, 6-mercaptopurine, cyclosporin A, cyclophosphamide and methotrexate are tested. A hope for the future is so-called biological treatment (anticytokines, monoclonal antibodies against cytokines, against CD4+ TNF, interleukines IL-10 and 11, immunoglobulin; plasmapheresis is also tested). Treatment must be individual and surgery as late as possible, only in case of complications, and should be very sparing, stenoses should be treated by plastic operations of strictures.

    2014-01-01

    A dynamic treatment regime consists of a sequence of decision rules, one per stage of intervention, that dictate how to individualize treatments to patients based on evolving treatment and covariate history. These regimes are particularly useful for managing chronic disorders, and fit well into the larger paradigm of personalized medicine. They provide one way to operationalize a clinical decision support system. Statistics plays a key role in the construction of evidence-based dynamic treatment regimes – informing best study design as well as efficient estimation and valid inference. Due to the many novel methodological challenges it offers, this area has been growing in popularity among statisticians in recent years. In this article, we review the key developments in this exciting field of research. In particular, we discuss the sequential multiple assignment randomized trial designs, estimation techniques like Q-learning and marginal structural models, and several inference techniques designed to address the associated non-standard asymptotics. We reference software, whenever available. We also outline some important future directions. PMID:25401119

    2015-09-01

    Onychomycosis or fungal infection of the toenail or fingernail is a common affliction. Approximately 10% of the world's adult population is estimated to suffer from onychomycosis. Current treatment options such as topical creams, oral drugs, or laser treatments are generally limited by a variety of problems. We present results for an alternative onychomycosis treatment scheme using atmospheric pressure cold air plasmas. Using thinned cow hoof as a model nail material, we tested the ability of various plasma sources to act through the model nail to eradicate either bacteria or fungus deposited on the opposite side. Following 20 minute exposure to a surface microdischarge (SMD) device operating in room air, we observed a ~ 2 log reduction of E. coli. A similar result was obtained against T. rubrum after 45 min plasma treatment. NOx species concentration penetrating through the model nail as well as uptake into the nail were measured as a function of nail thickness. We propose that these plasma-generated species, or perhaps their reaction products, are responsible for at least part of the observed anti-microbial effect. We also explore the use of ultraviolet light acting in synergy with plasma-generated chemical species.

  6. Novel preventive treatment options.

    PubMed

    2009-01-01

    A number of novel preventive treatment options which, as with traditional methods, can be differentiated into 3 categories of prevention (primary, secondary and tertiary), have been and are being currently investigated. Those reviewed are either commercially available or appear relatively close to that point. These include: approximal sealants; fluoride applications, including slow-release devices; measures to help remineralize demineralized tissue, including 3 different methods of delivering amorphous calcium phosphate; measures to help modify the biofilm to reduce the cariogenic challenge, including ozone therapy and probiotics; measures to increase enamel resistance to demineralization, including laser treatment of enamel, and a novel 'hybrid' technique for the treatment of primary molar caries which involves 'overlapping' of secondary and tertiary prevention--the Hall technique. Although many of these techniques show considerable promise and dentists should be aware of these developments and follow their progress, the evidence for each of these novel preventive treatment options is currently insufficient to make widespread recommendations. Changes in dental practice should be explored to see how oral health can be best supported through novel preventive systems. Further research is also required involving double-blind randomized controlled trials in order to bring further benefits of more effective caries control to patients. Implementation in practice should follow promptly as new techniques are shown to be clinically valuable for individual patients.

    The concept of mentalizing has captured the interest and imagination of an astonishing range of people—from psychoanalysts to neuroscientists, from child development researchers to geneticists, from existential philosophers to phenomenologists—all of whom seem to have found it useful. According to the Thompson Reuter maintained Web of Science, the use of the term in titles and abstracts of scientific papers increased from 10 to 2,750 between 1991 and 2011. Clinicians in particular have enthusiastically embraced the idea, and have put it to innovative use in their practices. Mentalization-based treatment (MBT)—making mentalizing a core focus of therapy—was initially developed for the treatment of borderline personality disorder (BPD) in routine clinical services delivered in group and individual modalities. Therapy with mentalizing as a central component is currently being developed for treatment of numerous groups, including people with antisocial personality disorder, substance abuse, eating disorders, and at-risk mothers with infants and children (A. Bateman & Fonagy, 2011). It is also being used with families and adolescents, in schools, and in managing social groups (Asen & Fonagy, 2011; Fonagy et al., 2009; Twemlow, Fonagy, & Sacco, 2005a, 2005b). In this article, we focus on MBT in the treatment of BPD. PMID:26157198

    Barateau, Lucie; Lopez, Régis; Dauvilliers, Yves

    2016-05-01

    Narcolepsy type 1 and narcolepsy type 2 are central disorders of hypersomnolence. Narcolepsy type 1 is characterized by excessive daytime sleepiness and cataplexy and is associated with hypocretin-1 deficiency. On the other hand, in narcolepsy type 2, cerebrospinal fluid hypocretin-1 levels are normal and cataplexy absent. Despite major advances in our understanding of narcolepsy mechanisms, its current management is only symptomatic. Treatment options may vary from a single drug that targets several symptoms, or multiple medications that each treats a specific symptom. In recent years, narcolepsy treatment has changed with the widespread use of modafinil/armodafinil for daytime sleepiness, antidepressants (selective serotonin and dual serotonin and noradrenalin reuptake inhibitors) for cataplexy, and sodium oxybate for both symptoms. Other psychostimulants can also be used, such as methylphenidate, pitolisant and rarely amphetamines, as third-line therapy. Importantly, clinically relevant subjective and objective measures of daytime sleepiness are required to monitor the treatment efficacy and to provide guidance on whether the treatment goals are met. Associated symptoms and comorbid conditions, such as hypnagogic/hypnopompic hallucinations, sleep paralysis, disturbed nighttime sleep, unpleasant dreams, REM- and non REM-related parasomnias, depressive symptoms, overweight/obesity, and obstructive sleep apnea, should also be taken into account and managed, if required. In the near future, the efficacy of new wake-promoting drugs, anticataplectic agents, hypocretin replacement therapy and immunotherapy at the early stages of the disease should also be evaluated.

    Organic and inorganic substances which were released into the environment as a result of domestic, agricultural and industrial water activities lead to organic and inorganic pollution. The normal primary and secondary treatment processes of these wastewaters have been introduced in a growing number of places, in order to eliminate the easily settled materials and to oxidize the organic material present in wastewater. The final result is a clear, apparently clean effluent which is discharged into natural water bodies. This secondary effluent is, however, loaded with inorganic nitrogen and phosphorus and causes eutrophication and more long-term problems because of refractory organics and heavy metals that are discharged. Microalgae culture offers an interesting step for wastewater treatments, because they provide a tertiary biotreatment coupled with the production of potentially valuable biomass, which can be used for several purposes. Microalgae cultures offer an elegant solution to tertiary and quandary treatments due to the ability of microalgae to use inorganic nitrogen and phosphorus for their growth. And also, for their capacity to remove heavy metals, as well as some toxic organic compounds, therefore, it does not lead to secondary pollution. In the current review we will highlight on the role of micro-algae in the treatment of wastewater. PMID:24936135

  2. Water treatment residuals

    SciTech Connect

    Billings, C.H.

    1994-01-01

    Solutions to an environmental problem often create other environmental problems. That surely is the case in the water supply field. By providing new or expanded water treatment systems to comply with the maximum contaminant levels and treatment mandates of the Safe Drinking Water Act, water purveyors are generating large volumes of residuals that must be managed, ultimately disposed of, or recycled. Numerous federal, state, and local laws govern the management, transport, disposal, and recycling of wastes produced by water treatment systems. Because these laws can result in exorbitant waste disposal costs, restricting some projects entirely, water suppliers need to consider residual disposal early in the siting, selection, and design of treatment projects. To inform water suppliers about residual laws, AWWA commissioned a study published as a Water Industry Technical Action Fund report. In addition to identifying and describing applicable laws at the federal level and in six of the states, the study revealed a series of findings as to the consequences of those laws to water suppliers. This article is a brief overview of the findings of the report.

    PubMed

    Besag, Frank M C

    2014-06-01

    There is increasing recognition that ADHD is a common condition, not only in children and teenagers but also in adults. This has led to a rapid rise in the number of women of childbearing age who are being treated for this condition. Against the background of concerns about the use of medication of any kind during pregnancy and breastfeeding, it is remarkable that there is so little information available on the effects of ADHD medication on the fetus and newborn. The impulsivity associated with ADHD might lead to an increased rate of unplanned pregnancy. Although treating ADHD during pregnancy and lactation might have negative effects on the baby, suspension of treatment or inadequate treatment could also place both mother and baby at risk. Pharmacodynamic and pharmacokinetic changes during pregnancy could affect both the efficacy and the concentration of medication. Again, there is almost no guidance available. The US Food and Drug Administration has classified ADHD medications as being "pregnancy category C", implying that there is insufficient information to confirm either harm or lack of harm. From the limited information that has been published, it would appear that the risk of fetal malformation, at least with methylphenidate, is very low and that the amounts of medication excreted in breast milk and consumed by the infant are very small. Three questions that both clinicians and patients are likely to ask are the following. Should ADHD medication be stopped before, during or after pregnancy, or should it be continued throughout? Should ADHD medication doses be adjusted during the course of the pregnancy or after delivery? Should breastfeeding be encouraged or discouraged? Discontinuing ADHD treatment could put both mother and baby at risk. This has to be balanced against the possible risks to the baby of continuing treatment. Although the data remain inadequate, the risk of the latter appears to be quite small, at least for methylphenidate. However, there is

    A sizable proportion of psychiatric patients will seek clinical evaluation and treatment for anxiety symptoms reportedly refractory to treatment. This apparent lack of response is either due to "pseudo-resistance" (a failure to have received and adhered to a recognized and effective treatment or treatments for their condition) or to true "treatment resistance." Pseudo-resistance can be due to clinician errors in selecting and delivering an appropriate treatment effectively, or to patient nonadherence to a course of treatment. True treatment resistance can be due to unrecognized exogenous anxiogenic factors (eg, caffeine overuse, sleep deprivation, use of alcohol or marijuana) or an incorrect diagnosis (eg, atypical bipolar illness, occult substance abuse, attention deficit-hyperactivity disorder). Once the above factors are eliminated, treatment should focus on combining effective medications and cognitive behavioral therapy, combining several medications (augmentation), or employing novel medications or psychotherapies not typically indicated as first-line evidence-based anxiety treatments.

    2011-09-01

    Melasma is a common, acquired facial skin disorder, mostly involving sun-exposed areas like cheeks, forehead and upper lip. Melasma occurs in both sexes, although almost 90 percent of the affected are women. It is more common in darker skin types (Fitzpatrick skin types IV to VI) especially Hispanics/Latinos, Asians and African-Americans. The onset of the melasma is at puberty or later, with exception of darker skin types, who tend to develop this problem in the first decade of life. The etiology is still unknown, although there are a number of triggering factors related to the onset of melasma. The most important are sun-exposure and genetic factors in both sexes, while hormonal activity has more important role in females. In addition, stress and some cosmetic products and drugs containing phototoxic agents can cause outbreaks of this condition. Melasma should be treated using monotherapies or combination of therapy, mainly fixed triple or dual combinations containing hydroquinone, tretinoin, corticosteroids or azelaic acid. Modified Kligman's formula is also very effective. Above mentioned therapy regimens in combination with UVA and UVB blocking sunscreens are mostly effective in epidermal melasma. Discontinuation of the use of birth control pills, scented cosmetic products, and phototoxic drugs coupled with UV protection are also benefitial in clearing of melasma. Alternative treatment including chemical peels and glicolic acid, seem to have the best result as a second line treatment after bleaching creams. Laser treatments show limited efficacy and should rarely be used in the treatment of melasma. Combining topical agents like hydroquinone, tretinoin and a corticosteroid in addition to sun avoidance, regular use of sunscreen throughout the year and patient education is the best treatment in this difficult to treat condition.

    Chronobiological treatments are non-pharmacological treatments that influence the circadian rhythms and the physiology of sleep. In these treatments, the sleep-wake cycle and exposure to environmental stimuli affecting the biological rhythms are controlled. The aim is to produce a therapeutic effect in the treatment of psychiatric disorders. Chronobiological treatments include manipulations of the sleep-wake cycle, like sleep deprivation and advanced sleep-wake rhythm, and scheduled exposures to light and darkness. The clinical use of chronobiological treatments in Finland has been minimal and limited to the treatment of mood disorders, especially depressive disorders.

    Although several effective drugs have in recent years been introduced for the treatment of disseminated breast cancer, it is still an incurable illness. Many patients live a fairly normal life with their illness for a long time, and some of them are able to continue working in spite of the therapies. Factors considered in tailoring the treatment include tumor subtype, extent of the disease, symptoms, previous treatments and the achieved treatment outcome, and adverse effects of the treatments.

    Pedophilia is only one of the sexual deviations that can be treated by chemical castration and it is presently unclear whether pedophilia responds better or worse to this therapy in sexual offenders. Antiandrogens are most often used for chemical castration. With respect to the treatment of sexual deviations, LH-antagonists or the combination of antiandrogens and LH-agonists were not studied very extensively. Long-term effects and side-effects of chemical castration are also presently unclear. Although, there is some indication that recidivism will decrease following chemical castration, its use is limited by a high refusal and drop-out rate. The indications of chemical castration in the treatment of sexual deviation raises important ethical questions.

    Summary Clavicle fractures are very common injuries in adults (2–5%) and children (10–15%) (1) and represent the 44–66% of all shoulder fractures (2). Despite the high frequency the choice of proper treatment is still a challenge for the orthopedic surgeon. With this review we wants to focus the attention on the basic epidemiology, anatomy, classification, evaluation and management of surgical treatments in relationship with the gravity of injuries. Both conservative and surgical management are possible, and surgeons must choose the most appropriate management modality according to the biologic age, functional demands, and type of lesion. We performed a review of the English literature thought PubMed to produce an evidence-based review of current concept and management of clavicle fracture. We finished taking a comparison with our survey in order to underline our direct experience. PMID:23905044

    Brachymetatarsia can be congenital, idiopathic or secondary and describes an abnormal shortening of a metatarsal bone. The indications for treatment are not only due to cosmesis. The shortening of a ray changes the biomechanics of the foot and can lead to metatarsalgia. A frequent clinical feature is dorsal dislocation of a toe causing painful shoe conflict and disturbed proprioception. There are three main options for operative correction: lengthening osteotomy, interposition of a tricortical bone and gradual lengthening by callus distraction. While one stage lengthening procedures such as osteotomy and interposition are more appropriate for correction of moderate length deficiencies, the callus distraction method is more suitable for larger elongation. Common to all procedures is a long-term treatment with a high risk of different complications whereby patient compliance can be problematical. PMID:23238881

    Gout is a severely disabling disorder, leading to poor quality of life, functional impairment with repercussion on physical activity, social functioning and emotional health. On the other hand, gout is probably the best understood and most manageable of all common systemic rheumatic diseases. The treatment of gout is appropriately divided into treatment of the acute attack and prevention of further attacks and of joint damage. Standard management of acute attacks of gout consists of rest, application of ice to the affected joint, and prescription of non-steroidal anti-inflammatory drugs, or glucocorticoids which should be started immediately to be most effective. Colchicin and interleukin-1 inhibitors can be used as alternative, when are indicated and available. Urate lowering therapy (usually alopurinol) is indicated to treat recurrent gout attacks, chronic arthropathy, tophi and uric acid renal lithiasis.

    Tobacco dependence causes every sixth death in the Czech Republic and is associated with diseases of the whole body. Treatment of tobacco dependence should be a standard part of clinical care to the extent of time available--from brief intervention at each clinical contact with patients up to intensive treatment. It includes psycho-socio-behavioural support and pharmacotherapy. It should apply to all professions in clinical medicine--as recommended by WHO mainly doctors, nurses, pharmacists and dentists, and should be covered within health care systems. Economically, it is one of the most cost-effective interventions in medicine. In our population over 15 years about 30% smokes (about 2.2 million people), diagnosis F17 relates to approximately 1.75 million people (about 80% of smokers). PMID:26955915

    Summary Pulmonary arterial hypertension (PAH) is a chronic progressive disease of the pulmonary vasculature characterized by elevated pulmonary arterial pressure and secondary right ventricular failure. PAH is considered a life-threatening condition unless treated. This article provides a comprehensive review of controlled and uncontrolled trials to define the risk-benefit for different therapeutic options of this clinical disorder. Relevant published articles were identified through searches of the National Center for Biotechnology PubMed database. All therapeutic measures for PAH were discussed. Six drugs have been approved in the United States for the treatment of PAH. Extensive medical advancement has been achieved in treatment of PAH. However, none of the approved therapies have shown ability to cure the disease. New research should be performed to develop promising new therapies. PMID:22460104

    Ascites is a common complication of hepatic cirrhosis and portal hypertension. Patients present systemic and splanchnic circulation disorders, which cause central hypovolemia and arterial hypotension, with the subsequent activation of vasoconstrictor systems and increased renal reabsorption of sodium and water. Approximately 5%-10% of patients present refractory ascites. Refractory ascites is considered when it is not controllable with standard dietary (sodium restriction) and diuretic (furosemide up to 160 mg a day and spironolactone up to 400mg a day) treatment or when patients present adverse effects due to diuretics that impede their administration at optimum dosages. The current therapeutic options for these patients are repeated evacuative paracentesis and the percutaneous intrahepatic portosystemic shunt. Despite these treatments, refractory ascites has a poor prognosis; patients should therefore be assessed for liver transplantation.

    1999-09-01

    A workshop on structured treatment interruptions (STI) took place in Boston in July 1999. The three basic reasons for initiating STI are to save or increase the immune system's response to HIV, to renew sensitivity to anti-HIV drugs, and to provide a break for people experiencing treatment fatigue or severe side effects. Discussions at the conference emphasized that research on STI is still preliminary and the benefits of STI are unclear at this time. The meeting concluded with a review of ongoing studies; a list of recommendations was proposed. Also discussed was the need to communicate a clear definition of STI that could be applied for large observational studies. A task force is being established to achieve this goal, which would include representatives from large studies. Contact information is provided. PMID:11367357

  10. Electrocoagulation in Water Treatment

    NASA Astrophysics Data System (ADS)

    Liu, Huijuan; Zhao, Xu; Qu, Jiuhui

    Electrocoagulation (EC) is an electrochemical method of treating polluted water where sacrificial anodes corrode to release active coagulant precursors (usually aluminum or iron cations) into solution. At the cathode, gas evolves (usually as hydrogen bubbles) accompanying electrolytic reactions. EC needs simple equipments and is designable for virtually any size. It is cost effective and easily operable. Specially, the recent technical improvements combined with a growing need for small-scale water treatment facilities have led to a revaluation of EC. In this chapter, the basic principle of EC was introduced first. Following that, reactions at the electrodes and electrode assignment were reviewed; electrode passivation process and activation method were presented; comparison between electrocoagulation and chemical coagulation was performed; typical design of the EC reactors was also described; and factors affecting electrocoagulation including current density, effect of conductivity, temperature, and pH were introduced in details. Finally, application of EC in water treatment was given in details.

    Impetigo is the most common bacterial skin infection in children two to five years of age. There are two principal types: nonbullous (70% of cases) and bullous (30% of cases). Nonbullous impetigo, or impetigo contagiosa, is caused by Staphylococcus aureus or Streptococcus pyogenes, and is characterized by honey-colored crusts on the face and extremities. Impetigo primarily affects the skin or secondarily infects insect bites, eczema, or herpetic lesions. Bullous impetigo, which is caused exclusively by S. aureus, results in large, flaccid bullae and is more likely to affect intertriginous areas. Both types usually resolve within two to three weeks without scarring, and complications are rare, with the most serious being poststreptococcal glomerulonephritis. Treatment includes topical antibiotics such as mupirocin, retapamulin, and fusidic acid. Oral antibiotic therapy can be used for impetigo with large bullae or when topical therapy is impractical. Amoxicillin/clavulanate, dicloxacillin, cephalexin, clindamycin, doxycycline, minocycline, trimethoprim/sulfamethoxazole, and macrolides are options, but penicillin is not. Natural therapies such as tea tree oil; olive, garlic, and coconut oils; and Manuka honey have been anecdotally successful, but lack sufficient evidence to recommend or dismiss them as treatment options. Treatments under development include minocycline foam and Ozenoxacin, a topical quinolone. Topical disinfectants are inferior to antibiotics and should not be used. Empiric treatment considerations have changed with the increasing prevalence of antibiotic-resistant bacteria, with methicillin-resistant S. aureus, macrolide-resistant streptococcus, and mupirocin-resistant streptococcus all documented. Fusidic acid, mupirocin, and retapamulin cover methicillin-susceptible S. aureus and streptococcal infections. Clindamycin proves helpful in suspected methicillin-resistant S. aureus infections. Trimethoprim/sulfamethoxazole covers methicillin-resistant S

    Immunosuppressive therapy is the main postoperative treatment for keratoplasty, but there are considerable differences in protocols for the use of steroids and other immunosuppressants. Therefore, we conducted 2 prospective randomized clinical trials and 1 prospective nonrandomized clinical trial on keratoplasty postoperative treatment. One study evaluated the efficacy and safety of long-term topical corticosteroids after a penetrating keratoplasty was performed. Patients who underwent keratoplasty and maintained graft clarity for >1 year were randomly assigned to either a steroid or a no-steroid group. At the 12-month follow-up, the no-steroid group developed significantly more endothelial rejection than did the steroid group. A second study elucidated the effectiveness and safety of systemic cyclosporine in high-risk corneal transplantation. The patients were assigned to a systemic cyclosporine or control group. At a mean follow-up of 42.7 months, no difference was observed in the endothelial rejection rates and graft clarity loss between the 2 groups. A third study elucidated the effectiveness and the safety of systemic tacrolimus in high-risk corneal transplantation. Of 11 consecutive eyes decompensated despite systemic cyclosporine treatment, there was no irreversible rejection in eyes treated with tacrolimus, which was significantly better than in previous penetrating keratoplasty with systemic cyclosporine treatment. Prognosis after keratoplasty in patients with keratoconus is relatively good, but special attention is required for patients with atopic dermatitis. Postkeratoplasty atopic sclerokeratitis (PKAS) is a severe form of sclerokeratitis after keratoplasty in atopic patients. Our retrospective study showed that 35 eyes of 29 patients from a total of 247 keratoconus eyes undergoing keratoplasty were associated with atopic dermatitis, of which 6 eyes of 5 patients developed PKAS. Eyes with PKAS had a significantly higher incidence of atopic blepharitis

    Opinion statement Preclinical and clinical research implicate several neurotransmitter systems in the pathophysiology of gambling disorder (GD). In particular, neurobiological research suggests alterations in serotonergic, dopaminergic, glutamatergic and opioidergic functioning. The relative efficacy of medications targeting these systems remains a topic of ongoing research, and there is currently no Food and Drug Administration (FDA) approved medication with an indication for GD. Considering co-occurring disorders may be particularly important when devising a treatment plan for GD: extant data suggest that the opioid antagonist naltrexone may by the most effective form of current pharmacotherapy for GD, particularly for individuals with a co-occurring substance-use disorder (SUD) or with a family history of alcoholism. In contrast, lithium or other mood stabilizers may be most effective for GD for patients presenting with a co-occurring bipolar-spectrum disorder (BSD). Further, serotonin reuptake inhibitors (SRIs) may be efficacious in reducing GD symptoms for individuals also presenting with a (non-BSD) mood or anxiety disorder. Finally, elevated rates of GD (and other Impulse Control Disorders; ICDs) have been noted among individuals with Parkinson’s Disease (PD), and clinicians should assess for vulnerability to GD when considering treatment options for PD. Reducing levodopa or dopamine agonist (DA) dosages may partially reduce GD symptoms among patients with co-occurring PD. For GD patients not willing to consider drug treatment, n-acetyl cysteine or behavioral therapies may be effective. Ongoing research into the effectiveness of combined behavioral and pharmacotherapies is being conducted; thus combined treatments should also be considered. PMID:24904757

    Thyroid hormone deficiency can have important repercussions. Treatment with thyroid hormone in replacement doses is essential in patients with hypothyroidism. In this review, we critically discuss the thyroid hormone formulations that are available and approaches to correct replacement therapy with thyroid hormone in primary and central hypothyroidism in different periods of life such as pregnancy, birth, infancy, childhood, and adolescence as well as in adult patients, the elderly, and in patients with comorbidities. Despite the frequent and long term use of l-T4, several studies have documented frequent under- and overtreatment during replacement therapy in hypothyroid patients. We assess the factors determining l-T4 requirements (sex, age, gender, menstrual status, body weight, and lean body mass), the major causes of failure to achieve optimal serum TSH levels in undertreated patients (poor patient compliance, timing of l-T4 administration, interferences with absorption, gastrointestinal diseases, and drugs), and the adverse consequences of unintentional TSH suppression in overtreated patients. Opinions differ regarding the treatment of mild thyroid hormone deficiency, and we examine the recent evidence favoring treatment of this condition. New data suggesting that combined therapy with T3 and T4 could be indicated in some patients with hypothyroidism are assessed, and the indications for TSH suppression with l-T4 in patients with euthyroid multinodular goiter and in those with differentiated thyroid cancer are reviewed. Lastly, we address the potential use of thyroid hormones or their analogs in obese patients and in severe cardiac diseases, dyslipidemia, and nonthyroidal illnesses.

    Giardia lamblia is both the most common intestinal parasite in the United States and a frequent cause of diarrheal illness throughout the world. In spite of its recognition as an important human pathogen, there have been relatively few agents used in therapy. This paper discusses each class of drugs used in treatment, along with their mechanism of action, in vitro and clinical efficacy, and side effects and contraindications. Recommendations are made for the preferred treatment in different clinical situations. The greatest clinical experience is with the nitroimidazole drugs, i.e., metronidazole, tinidazole, and ornidazole, which are highly effective. A 5- to 7-day course of metronidazole can be expected to cure over 90% of individuals, and a single dose of tinidazole or ornidazole will cure a similar number. Quinacrine, which is no longer produced in the United States, has excellent efficacy but may be poorly tolerated, especially in children. Furazolidone is an effective alternative but must be administered four times a day for 7 to 10 days. Paromomycin may be used during early pregnancy, because it is not systematically absorbed, but it is not always effective. Patients who have resistant infection can usually be cured by a prolonged course of treatment with a combination of a nitroimidazole with quinacrine. PMID:11148005

    Full and accurate diagnosis of allergic rhinitis is important as a basis for treatment decisions, as many nasal disorders have similar signs and symptoms. Optimal allergen avoidance is the starting point of treatment, so causative allergens need to be identified. Oral antihistamines are effective in relieving the majority of symptoms of allergic rhinitis and allergic conjunctivitis, but provide only partial relief from nasal congestion. Topical alpha-adrenergic decongestants help to relieve congestion, but prolonged use leads to rhinitis medicamentosa. Systemic decongestants are less effective than topical agents and their use is limited by systemic and central side-effects. The value of leukotriene antagonists has yet to be fully evaluated. Intranasal ipratropium bromide helps to control watery secretions, and an aerosol may be more effective than an aqueous solution. Topical glucocorticosteroids, such as triamcinolone, are the most potent and effective agents available for treating allergic rhinitis. The available evidence indicates that there is very little systemic absorption. Sodium cromoglycate is effective in allergic rhinitis, though less so than topical steroids, and has the least adverse effects among the antiallergic agents. Immunotherapy can be effective and may be indicated in individuals who cannot avoid the causative allergen. Special considerations apply to the treatment of allergic rhinitis in elderly or pregnant patients. Finally, patients with long-standing allergic conditions should be re-assessed regularly.

    Schizophrenia is a psychiatric disorder that causes severe cognitive, behavioral and social dysfunction, responsible for a shortening of the life expectancy of patients, with an increased risk of suicide, cardiovascular disease and cancer. The management of patient with schizophrenia is global and atypical antipsychotics, antagonizing dopamine pathway, are the first line pharmacological treatment. Clozapine, the first atypical antipsychotic discovered, is currently still the most effective molecule against schizophrenia, while causing less extrapyramidal side effects. Its particular pharmacological behavior towards serotonergic, muscarinic and NMDA receptors, seems essential to its action. However, clozapine is responsible for immunological and metabolic lethal adverse events, preventing its wider use. Clozapine is therefore reserved for resistant schizophrenia cases. Monitoring patients with different scales such as the Brief Psychiatric Rating Scale and the Positive And Negative Syndrome Scale showed that there were forms of ultra-resistant schizophrenia. The treatment in this case, must be customized to the patient's symptomatology, but the combination of clozapine with other pharmacological or non-pharmacological treatments, shows yet only small improvements.

    Following the death of a loved one, a small group of grievers develop an abnormal grieving style, termed complicated or prolonged grief. In the effort to establish complicated grief as a disorder in DSM and ICD, several attempts have been made over the past two decades to establish symptom criteria for this form of grieving. Complicated grief is different from depression and PTSD yet often comorbid with other psychological disorders. Meta-analyses of grief interventions show small to medium effect sizes, with only few studies yielding large effect sizes. In this article, an integrative cognitive behavioral treatment manual for complicated grief disorder (CG-CBT) of 25 individual sessions is described. Three treatment phases, each entailing several treatment strategies, allow patients to stabilize, explore, and confront the most painful aspects of the loss, and finally to integrate and transform their grief. Core aspects are cognitive restructuring and confrontation. Special attention is given to practical exercises. This article includes the case report of a woman whose daughter committed suicide.

    Animal experiments have explored the structural and functional alterations of the afferent visual pathways in amblyopia and have emphasized the extraordinary sensitivity of the immature visual system to abnormal visual stimulation. The practical consequences of these experiments are obvious: early diagnosis of amblyopia and energetic occlusion therapy as early in life as possible. At the same time, measures must be taken to prevent visual deprivation amblyopia in the occluded eye. After successful treatment, alternating penalization with two pairs of spectacles is recommended. Pleoptics involves an enormous commitment in terms of time, personnel and costs. In view of the fact that the superiority of this treatment over occlusion therapy has yet to be proven, the current value of pleoptics appears dubious. Moreover, overtreated patients may end up with intractable diplopia. Diverging opinions exist with regard to the use of penalization as a primary treatment of amblyopia. We employ it only in special cases as an alternative to occlusion therapy. Visual deprivation in infancy caused by opacities of the ocular media, especially when they occur unilaterally, must be eliminated, and deprivation amblyopia must be treated without delay to regain useful vision. Brief periods of bilateral occlusion are recommended to avoid the highly amblyopiogenic imbalance between binocular afferent visual input. Future developments will hopefully include new objective methods to diagnose amblyopia in preverbal children and infants. The application of positron emission tomography is perhaps the first step in the direction of searching for new approaches to this problem.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2083896

    Progress in understanding the neuroscience of addiction has significantly advanced the development of more efficacious medications for the treatment of alcohol use disorders (AUD). While several medications have been approved by regulatory bodies around the world for the treatment of AUD, they are not universally efficacious. Recent research has yielded improved understanding of the genetics and brain circuits that underlie alcohol reward and its habitual use. This research has contributed to pharmacogenetic studies of medication response, and will ultimately lead to a more "personalized medicine" approach to AUD pharmacotherapy. This chapter summarizes work on clinically available medications (both approved by regulatory bodies and investigational) for the treatment of alcohol dependence, as well as the psychiatric disorders that are commonly comorbid with AUD. Studies that have evaluated genetic influences on medication response and those that have employed neuroimaging to probe mechanisms of medication action or response are highlighted. Finally, new targets discovered in animal models for possible pharmacologic intervention in humans are overviewed and future directions in medications development provided.

    The author reviews the prevalence of onychomycoses and the factors influencing it. Among the precipitating factors, age and various predisposing diseases play a role in the development of the disease play a role in the development of the disease. The problem affects the toenails more frequently than the fingernails. Distal subungual onychomycosis caused by dermatophytons is most often seen among the various types of the disease. Yeasts and moulds mainly act as contaminants. New diagnostic methods facilitate more precise diagnosis but they cannot replace basic mycological investigations. Orally administered antifungal agents have appeared in the foreground of treatment. Among them fluconazole, itraconazole and terbinafin derivatives can safely be applied in combination with certain cauterants. Each of the three agents are effective in approximately 70-80% of cases, especially when applied on fingernails. Combined therapy, such as the application of oral antimycotics and antifungal lacquerers or oral treatment accompanied by the surgical, laser or chemical removal of the affected nail regions, can improve the results. Surviving fungal residues in the substance of the nail may restart the disease. Relapse may also be attributed to neglecting the desinfection of shoes. When choosing the drugs, drug interaction should also be considered. The above three oral antimycotics have few (1-20%) side effects, gastrointestinal ones being the most common among them. A transitory elevation in hepatic enzyme levels may sometimes occur but the changes go back to normal after treatment is over.

  7. Nonsurgical periodontal treatment.

    Aimetti, Mario

    2014-01-01

    The primary goal of nonsurgical periodontal therapy is to control microbial periodontal infection by removing bacterial biofilm, calculus, and toxins from periodontally involved root surfaces. A review of the scientific literature indicates that mechanical nonsurgical periodontal treatment predictably reduces the levels of inflammation and probing pocket depths, increases the clinical attachment level and results in an apical shift of the gingival margin. Another parameter to be considered, in spite of the lack of scientific evidence, is the reduction in the degree of tooth mobility, as clinically experienced. It is important to point out that nonsurgical periodontal treatment presents limitations such as the long-term maintainability of deep periodontal pockets, the risk of disease recurrence, and the skill of the operator. A high number of posttreatment residual pockets exhibiting bleeding on probing and > 5 mm deep are related to lower clinical stability. The successful treatment of plaque-induced periodontitis will restore periodontal health, but with reduced periodontium. In such cases, anatomical damage from previous periodontal disease will persist and inverse architecture of soft tissue may impair home plaque removal. The clinician can select one of the following therapeutic options according to the individual patient's needs: - Quadrant/sextant wise instrumentation (conventional staged debridement, CSD). - Instrumentation of all pockets within a 24-hour period with (full mouth disinfection [FMD]) or without (full mouth scaling and root planing [FMSRP]) local antiseptics. Both procedures can be associated with systemic antimicrobials. -CSD or FMD in combination with laser or photodynamic therapy.

    The influence of six fungicides (famoxadone, fenhexamid, fluquinconazole, kresoxim-methyl, quinoxyfen and trifloxystrobin) on the volatile composition of red wines obtained from inoculated fermentation was studied. Although treatments were carried out under critical agricultural practices (CAP), the residues in the wines were below their maximum residue limit (MRL). Ethyl decanoate was the compound most influenced by these fungicides, while diethyl succinate, decanoic acid, β-ionone, and citronellol concentration were not changed with any of the treatments. The treatment of grapes with trifloxystrobin induced changes in only one volatile compound, and the variation in volatile composition of wines from grapes treated with fenhexamid, fluquinconazole and quinoxyfen compared to control wines was almost negligible invaluable. The treatment with famoxadone influenced more volatile compounds than the other ones, except for wine from grapes treated with kresoxim-methyl, which was the only wine that showed a big change in its aromatic composition.

    Anti-epileptic drugs are the mainstay in the management of epilepsy. However, approximately 30% of patients continue to have seizures despite optimal drug therapy. Behavioural interventions that include biofeedback have become increasingly popular over the last 3 decades, and the results have mostly been encouraging. Biofeedback is a non-invasive behavioural treatment that enables a patient to gain volitional control over a physiological process. In epilepsy, targeted parameters for biofeedback include electroencephalographic (EEG) measures of cortical activity, such as different EEG frequencies or cortical potentials (i.e., neurofeedback), and peripheral autonomic activity, such as Galvanic Skin Response (GSR). In this review, biofeedback using Sensory Motor Rhythm (SMR), Slow Cortical Potentials (SCP), and GSR are discussed. SMR biofeedback was established in the 1970s and is the most prominent methodology for biofeedback treatment of epilepsy in published literature. The technique is now regaining its popularity. SCP biofeedback was introduced in the 1990s. In contrast to SMR biofeedback, which modulates the frequency components of EEG, SCP biofeedback focuses on the regulation of potential changes (amplitude of DC shift). The clinical trials conducted using SCP biofeedback were larger than those conducted using SMR biofeedback, and their overall outcomes were promising. GSR biofeedback is a relatively new methodology in its application to epilepsy and focuses on the modulation of electrodermal measures of sympathetic activity. Compared to the neurofeedback approach, GSR biofeedback is much easier to implement, and evidence suggests that its clinical benefits can be achieved more rapidly. Although the biofeedback treatment may never achieve the status of an alternative to pharmacotherapy for epilepsy, current research findings strongly suggest that biofeedback has the potential to become a potent adjunctive non-pharmacological approach to reduce seizure

  10. [Treatment of syncope].

    PubMed

    Andresen, D

    2014-06-01

    The therapy of patients with syncope is oriented to the underlying pathophysiological mechanisms. Patients with reflex syncope require careful education regarding recognition of warning signs and the avoidance of trigger factors. Treatment with beta blockers is nowadays obsolete. Even other drugs have failed to show any benefit. Pacemaker therapy should only be considered if syncope attacks are frequent and if there is a correlation between symptoms and the electrocardiogram (ECG). Because autonomic failure in patients with orthostatic hypotension is often drug-induced, reduction of the dosage or the complete elimination is the treatment of choice in these patients. A higher than normal salt and fluid intake as well as general measures to avoid delayed venous backflow, e.g. elastic stockings, may also be helpful. A change in blood pressure medication can be decisive for therapy success, especially in elderly patients with arterial hypertension. Pacemaker and defibrillator therapy is the treatment of choice in patients with bradycardia and tachycardia arrhythmias, respectively. Although these measures are simple but effective, in individual cases it is still difficult to find clinical proof that arrhythmic disorders are the causal factors for the syncope. However, also in these patients cardiac pacing should be based on a symptom ECG correlation. The recently conducted market release of the injectable miniaturized ECG recorder will alleviate the diagnostic process. The limits of this approach, however, become obvious when there is the suspicion of a life-threatening rhythm disorder, because the only difference between syncope and sudden cardiac death is that in one case the patient wakes up again.

  11. Treatment of Alzheimer disease.

    2011-06-15

    Alzheimer disease is the most common form of dementia, affecting nearly one-half [corrected] of Americans older than 85 years. It is characterized by progressive memory loss and cognitive decline. Amyloid plaque accumulation, neurofibrillary tau tangles, and depletion of acetylcholine are among the pathologic manifestations of Alzheimer disease. Although there are no proven modalities for preventing Alzheimer disease, hypertension treatment, omega-3 fatty acid supplementation, physical activity, and cognitive engagement demonstrate modest potential. Acetylcholinesterase inhibitors are first-line medications for the treatment of Alzheimer disease, and are associated with mild improvements in cognitive function, behavior, and activities of daily living; however, the clinical relevance of these effects is unclear. The most common adverse effects of acetylcholinesterase inhibitors are nausea, vomiting, diarrhea, dizziness, confusion, and cardiac arrhythmias. Short-term use of the N-methyl-D-aspartate receptor antagonist memantine can modestly improve measures of cognition, behavior, and activities of daily living in patients with moderate to severe Alzheimer disease. Memantine can also be used in combination with acetylcholinesterase inhibitors. Memantine is generally well tolerated, but whether its benefits produce clinically meaningful improvement is controversial. Although N-methyl-D-aspartate receptor antagonists and acetylcholinesterase inhibitors can slow the progression of Alzheimer disease, no pharmacologic agents can reverse the progression. Atypical antipsychotics can improve some behavioral symptoms, but have been associated with increased mortality rates in older patients with dementia. There is conflicting evidence about the benefit of selegiline, testosterone, and ginkgo for the treatment of Alzheimer disease. There is no evidence supporting the beneficial effects of vitamin E, estrogen, or nonsteroidal anti-inflammatory drug therapy.

  12. Ayahuasca and cancer treatment

    PubMed Central

    2013-01-01

    Objectives: Comprehensively review the evidence regarding the use of ayahuasca, an Amerindian medicine traditionally used to treat many different illnesses and diseases, to treat some types of cancer. Methods: An in-depth review of the literature was conducted using PubMed, books, institutional magazines, conferences and online texts in nonprofessional sources regarding the biomedical knowledge about ayahuasca in general with a specific focus in its possible relations to the treatment of cancer. Results: At least nine case reports regarding the use of ayahuasca in the treatment of prostate, brain, ovarian, uterine, stomach, breast, and colon cancers were found. Several of these were considered improvements, one case was considered worse, and one case was rated as difficult to evaluate. A theoretical model is presented which explains these effects at the cellular, molecular, and psychosocial levels. Particular attention is given to ayahuasca’s pharmacological effects through the activity of N,N-dimethyltryptamine at intracellular sigma-1 receptors. The effects of other components of ayahuasca, such as harmine, tetrahydroharmine, and harmaline, are also considered. Conclusion: The proposed model, based on the molecular and cellular biology of ayahuasca’s known active components and the available clinical reports, suggests that these accounts may have consistent biological underpinnings. Further study of ayahuasca’s possible antitumor effects is important because cancer patients continue to seek out this traditional medicine. Consequently, based on the social and anthropological observations of the use of this brew, suggestions are provided for further research into the safety and efficacy of ayahuasca as a possible medicinal aid in the treatment of cancer.

  13. Dream disorders and treatment.

    2007-09-01

    Consensus does not exist regarding what should constitute a "dream disorder." Conditions with disordered dreaming may be thought of as primary (ie, arising from changes in dreaming per se) or secondary to extrinsic disorders that impinge on structures involved in dreaming. The major primary disorder of dreaming, nightmare disorder, is covered in depth in this article. Definition of nightmare, diagnostic criteria for nightmare disorder, and differential diagnosis are discussed. The value of a sleep-disorders perspective on nightmares, and the possible exacerbating effects of sleep disorders that cause arousals, are indicated. The importance of a perspective that appreciates nightmares as richly and personally meaningful, with links to complex psychological factors present and past, is emphasized. Two types of treatment approaches are discussed: approaches that target the symptom of nightmares in relative isolation, and approaches that aim at working out psychological issues viewed as causing nightmares and a variety of other interconnected symptoms and problems. The former type of treatment includes the cognitive-behavioral approach "imagery rehearsal therapy," and the medication prazosin. The latter approach entails exploratory or psychodynamic psychotherapies. The approaches are seen as so different in scope, aim, and conceptual framework as to defy ready comparison. I think that a thorough psychological/psychiatric evaluation is essential for informed consideration in conjunction with the patient's choice of treatment approach. Sleep terrors are discussed as a non-rapid eye movement sleep arousal disorder that at times may be linked to broader psychological issues warranting consideration of psychotherapy. Brief summaries are provided of dream disorders secondary to other sleep disorders, drug and alcohol effects, medical disorders, and organic brain damage.

    A new powdered-carbon treatment process is being developed for the elimination of the present problems, associated with the disposal of biologically active sewage waste solids, and with water reuse. This counter-current flow process produces an activated carbon, which is obtained from the pyrolysis of the sewage solids, and utilizes this material to remove the adulterating materials from the water. Additional advantages of the process are the elimination of odors, the removal of heavy metals, and the potential for energy conservation.

    A furnace heats through both infrared radiation and convective air utilizing an infrared/purge gas design that enables improved temperature control to enable more uniform treatment of workpieces. The furnace utilizes lamps, the electrical end connections of which are located in an enclosure outside the furnace chamber, with the lamps extending into the furnace chamber through openings in the wall of the chamber. The enclosure is purged with gas, which gas flows from the enclosure into the furnace chamber via the openings in the wall of the chamber so that the gas flows above and around the lamps and is heated to form a convective mechanism in heating parts.

    Acne scarring is common but surprisingly difficult to treat. Scars can involve textural change in the superficial and deep dermis, and can also be associated with erythema, and less often, pigmentary change. In general, treatment of acne scarring is a multistep procedure. First, examination of the patient is necessary to classify the subtypes of scarring that are present. Then, the patient's primary concerns are elicited, and the patient is offered a menu of procedures that may address the various components of the scarring process. It is important to emphasize to the patient that acne scarring can be improved but never entirely reversed. PMID:17180246

    An article of an alloy of AISI 316 stainless steel is reduced in size to predetermined dimensions by cold working in repeated steps. Before the last reduction step the article is annealed by heating within a temperature range, specifically between 1010.degree. C. and 1038.degree. C. for a time interval between 90 and 60 seconds depending on the actual temperature. By this treatment the swelling under neutron bombardment by epithermal neutrons is reduced while substantial recrystallization does not occur in actual use for a time interval of at least of the order of 5000 hours.

    Atherosclerotic cardiovascular disease (including coronary heart disease, stroke and peripheral arterial disease) is the leading cause of death globally. Abnormal blood lipids (dyslipidemia), smoking, and high blood pressure are responsible for more than 75% of cases. Aggressive low-density lipoprotein (LDL)-cholesterol lowering therapy, particularly statins, appear to be the most effective of the therapeutic approaches, but even with their use, cardiovascular disease event rates remain relatively high, underpinning the quest for novel treatments. In this review we discuss recent advances in the field and what remains to be done to reduce this rate further. In particular, in addition to development and investigation of new LDL-cholesterol lowering therapies, there has been a major focus on treatments to favorably influence high-density lipoprotein (HDL)-cholesterol and triglyceride concentrations. However, to this time, approaches to the latter have been somewhat disappointing, but they may have particular benefits in people with diabetes. As atherosclerosis is a largely preventable process, which is driven particularly by behavioral and lifestyle factors, attention to other modifiable risk factors is imperative. PMID:24669298

    1992-12-01

    Patients with bilateral urolithiasis diagnosed at their first visit were followed for at least one year after the start of treatment. In this retrospective study of 123 patients, the basic metabolic workup revealed no specific underlying cause of simultaneously occurring bilateral nephrolithiasis, and none of the currently used therapeutic regimes proved to be efficient in attaining clinically acceptable stone-free rates at the 3, 6 and 12-month follow-ups. Of 38 patients treated with extracorporeal shockwave lithotripsy (SWL), 21 underwent treatment of both kidneys and 10 (48%) were free of stones bilaterally after 12 months. All of the 17 patients treated with unilateral SWL failed to achieve a stone-free state on the contralateral side. In another group, treated with medication alone to minimize risks of stone recurrence, only 3 of 26 (11.5%) patients were stone-free on both sides 12 months after the start of medication. Since we achieved a stone-free state of both kidneys in no more than 12% of the non-medicated cases, it seems warranted to treat bilateral urolithiasis with SWL more frequently, particularly when patients cannot return regularly to the stone clinic for a longterm follow-up.

  1. Causalgia pathogenesis and treatment.

    PubMed

    KUENKEL, V H

    1952-12-01

    Gross and microscopic anatomical evidence indicates that pain fibers involved in causalgia are those distributed to blood vessels-possibly to the arterioles-and that, for the greater part, these fibers constitute part of the general visceral afferent system. Several investigators have reported evidence that injury to a peripheral nerve of such a type as to cause damage to the vasomotor control of any area produces the initial pain in an extremity, and it is predicated that the arteriolar constriction causing the pain is then prolonged by the sensitization of arteriolar smooth muscle to the amount of epinephrine normally in the blood. If the condition is not treated, tissue anoxia occurs to such an extent that irreversible changes take place in the affected area.Treatment of causalgia in the lower extremities is directed toward interruption of either the vasomotor or afferent supply of blood vessels by blocking or excision of the second to fourth lumbar ganglia inclusive with the intervening chains. For the upper extremities, the blocking or disconnection of the second and third thoracic ganglia with interruption of the sympathetic chain between the third and fourth ganglia is considered a feasible method of treatment which does not produce the concomitant disability of Horner's syndrome.

    A recent revision of the proposed DSM III description of the borderline category is presented with reference to the work of Masterson (1972) and Grinker (1968). The contributions of Roger Shapiro et al. to a psychoanalytic formulation of the developmental and familial dynamics are summarized with reference to the genetic factors and the lack of validation to date of any general hypothesis. Treatment recommendations of Wolberg, Shapiro and Jacobson (1971) are described. Grinker's operational criteria were chosen for the pilot study: a defect in affectional relationships with no enduring close ties; child-like angry relationships with parental or authority figures, particularly in the dysphoric group; low self-esteem very poor sense of identity; a chronic depression characterized more by loneliness and boredom than by guilt or loss, and a pervading sense of anger or resentment. Cases are presented to illustrate treatment strategies. A brief differential diagnostic statement is made describing "borderline" as a separate category from other disorders manifesting oppositional, antisocial, and violent behavior.

    Tourette's syndrome (TS) consists of chronic motor and phonic tics and characteristically begins in childhood. The tics can be disabling and commonly associated behavioral comorbities such as attention deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD), can also cause problems in daily functioning. The underlying etiology and neurobiology of TS remain unknown although genetic factors appear to be important, cortical control of basal ganglia motor function appears to be disturbed and neurochemical abnormalities, particularly involving dopamine neurotransmission, are likely present. The treatment of TS involves appropriate education and support. Tics can be treated with habit reversal cognitive behavioral therapy, medications (most commonly alpha agonists and antipsychotics), local intramuscular injections of botulinum toxin and some severe, refractory cases have responded to deep brain stimulation surgery (DBS). It is important to appropriately diagnose and treat comorbid behavioral disorders that are disrupting function. OCD can be treated with cognitive behavioral therapy, selective serotonin reuptake inhibitors, and atypical antipsychotics. DBS has become a treatment option for patients with disabling OCD despite other therapies. ADHD is treated with appropriate classroom accommodations, behavioral therapy, alpha agonists, atomoxetine or methylphenidate-containing stimulant drugs. PMID:24043501

  5. Traditional preventive treatment options.

    2009-01-01

    Preventive treatment options can be divided into primary, secondary and tertiary prevention techniques, which can involve patient- or professionally applied methods. These include: oral hygiene (instruction), pit and fissure sealants ('temporary' or 'permanent'), fluoride applications (patient- or professionally applied), dietary assessment and advice (modification), other measures to help remineralize demineralized tissue and other measures to help modify the biofilm to reduce the cariogenic challenge. There is a considerable body of strong evidence supporting the use of specific techniques for primary prevention of caries in children, e.g. pit and fissure sealants and topically applied fluorides (including patient-applied fluoride toothpastes and professionally applied fluoride varnishes), but limited strong evidence for these techniques for secondary prevention--i.e. where early to established lesions with ICDAS codes 1-4 (and also the severer lesions coded 5 or 6) are involved--and in relation to adults. This lack of evidence reflects a shortage of high-quality trials in the area, as opposed to a series of good studies showing no effect. Since there is also limited longitudinal evidence supporting conventional operative care, and since controlling the caries process prior to first restoration is the key to breaking the repair cycle and improving care for patients, future research should address the shortcomings in the current level of supporting evidence for the various traditional preventive treatment options.

    There are an increasing number of more novel options available for operative intervention. This chapter outlines a series of operative treatment options which are available to the modern clinician to select from once a decision has been made to treat a carious lesion operatively. A series of novel methods of caries removal have been described; including chemomechanical caries removal, air abrasion, sono-abrasion, polymer rotary burs and lasers. There are also novel approaches to ensure complete caries removal and novel approaches for the management of deep caries. A novel question increasingly asked by clinicians is: does all the caries need to be removed? Operative management options here include: therapeutic fissure sealants, ultraconservative caries removal, stepwise excavation and the Hall technique. In conclusion, there is now a growing wealth of evidence that questions the traditional methods of caries removal and restoring the tooth. In parallel, there is a growing movement exploring the merits of therapeutically sealing caries into the tooth. This philosophy is alien to many of today's dentists and, until further randomized controlled trials are carried out in primary care, prudent caution must be exercised with this promising approach. Research is required into techniques which will allow monitoring of sealed caries to detect any rare, but insidious, failures. These novel techniques are an alternative way of managing the later stages of the caries process from a sounder biological basis and have marked potential benefits to patients from treatment, pain and outcome perspectives.

    The purpose of this paper is to analyze the current evolutions on nanotechnology and its applications on cancer theragnostics.Rapid advances and emerging technologies in nanotechnology are having a profound impact on cancer treatment. Applications of nanotechnology, which include liposomes, nanoparticles, polymeric micelles, dendrimers, nanocantilever, carbon nanotubes and quantum dots have significantly revolutionized cancer theragnostics. From a pharmaceutical viewpoint, it is critical that the biodistribution of active agents has to be controlled as much as possible. This aspect is vital in order to assure the proper efficiency and safety of the anticancer agents. These biocompatible nanocomposites provide specific biochemical interactions with receptors expressed on the surface of cancer cells. With passive or active targeting strategies, an increased intracellular concentration of drugs can be achieved in cancer cells , while normal cells are being protected from the drug simultaneously. Thus, nanotechnology restricts the extent of the adverse effects of the anticancer therapy. Treatment for metastatic breast cancer, sarcoma in AIDS patients, ovarian and lung cancer is already on market or under final phases of many clinical trials, showing remarkable results. As nanotechnology is perfected, side effects due to normal cell damage will decrease, leading to better results and lengthening patient's survival.

    Surgical removal of as much tumor mass as possible is usually considered the first step of treatment in acromegaly, unless the patients are unfit for surgery or refuse an operation. To date, in almost all cases, minimally invasive, transsphenoidal microscopic or endoscopic approaches are used. Whether a curative approach is feasible or a debulking procedure is planned, can be anticipated on the basis of preoperative magnetic resonance imaging. It mostly depends on localization, size, and the invasive character of the lesion. The surgical results depend on tumor-related factors such as size, extension, the presence or absence of invasion, and the magnitude of IGF-1 and growth hormone oversecretion, respectively. However, even surgeon-related factors such as experience and case load of the centers have been shown to strongly affect surgical results and complication rates. A reoperation can be considered at various stages in the treatment algorithm. There are several new technical gadgets which might aid in the surgical procedure: navigation, the Doppler probe, and variants of intraoperative imaging.

    2012-04-01

    Bronchoscopic techniques for the management of emphysema have evolved from the success of surgical treatment. Lung volume reduction surgery (LVRS) involves the removal of 20% to 30% of each lung and targets the most emphysematous segments. Patients with heterogeneous upper lobe emphysema and a low baseline exercise capacity have been identified as a subgroup within COPD in whom mortality benefits can even be achieved, along with improvements in exercise capacity and quality of life. Increased short-term mortality of approximately 5% and postoperative morbidity are the main limitations of LVRS. The extremely restrictive selection criteria for LVRS coupled with the relatively high mortality/morbidity have been the impetus for developing less invasive endoscopic modalities. Bronchoscopic lung volume reduction (BLVR) researchers have pursued various approaches using a range of modalities, such as blockers, stents, valves, sealants, and implants. BLVR appears to be safer than LVRS in terms of mortality and morbidity. This safety profile presents an attractive alternative for patients with COPD who are fragile physiologically because of the severity of their lung disease and the presence of co-morbid illnesses. The current report aims to describe the various minimally invasive modalities available for the treatment of emphysema. PMID:22616152

    In spite of long traditions, treatments utilizing radon-rich air or water have not been unequivocally embraced by modern medicine. The objective of this work is to examine factors that contribute to this continuing controversy. While the exact mechanism of radon's effect on human body is not completely understood, recent advances in radiobiology offer new insights into biochemical processes occurring at low-level exposures to ionizing radiation. Medical evidence and patients' testimonials regarding effectiveness of radon spa treatments of various ailments, most notably rheumatoid arthritis are accumulating worldwide. They challenge the premise of the Linear-No-Threshold (LNT) theory that the dose-effect response is the same per unit dose regardless of the total dose. Historically, such inference overshadowed scientific inquiries into the low-dose region and lead to a popular belief that no amount of radiation can be good. Fortunately, the LNT theory, which lacks any scientific basis, did not remain unchallenged. As the reviewed literature suggests, a paradigm shift, reflected in the consideration of hormetic effects at low-doses, is gaining momentum in the scientific community worldwide. The impetus comes from significant evidence of adaptive and stimulatory effects of low-levels of radiation on human immune system. PMID:18648641

    Solid formation in filtered leachates and wash solutions was seen in five of the six sludges treated by Enhanced Sludge Washing. Solid formation in process solutions takes a variety of forms: very fine particles, larger particulate solids, solids floating in solution like egg whites, gels, crystals, and coatings on sample containers. A gel-like material that formed in a filtered leachate from Enhanced Sludge Washing of Hanford T-104 sludge was identified as natrophosphate, Na{sub 7}(PO{sub 4}){sub 2}F{center_dot}19H{sub 2}O. A particulate material that formed in a filtered caustic leachate from Hanford SX-113 sludge contained sodium and silicon. This could be any of a host of sodium silicates in the NaOH-SiO{sub 2}-H{sub 2}O system. Acidic treatment of Hanford B-202 sludge with 1 M, 3 M, and 6 M HNO{sub 3} sequential leaching resulted in complete dissolution at 75 C, but not at ambient temperature. This treatment resulted in the formation of solids in filtered leachates. Analyses of the solids revealed that a gel material contained silica with some potassium, calcium, iron, and manganese. Two phases were embedded in the gel. One was barium sulfate. The other could not be identified, but it was determined that the only metal it contained was bismuth.

    Human papilloma viruses (HPV) lead to common warts in 5% of the population and genital warts in 1% of sexually-active individuals. Although about 50% of HPV infections regress spontaneously, the course is uncertain. Expectant waiting often leads to progression and dissemination. Plantar warts may cause pain on walking, while palmar and genital warts may impair social contacts. There are many treatments for warts, including a variety of laser systems. The CO(2) laser is the best ablative approach, producing cure rates of up to 75% for therapy-resistant common warts in cohort and case-control studies. Side effects such as bleeding, pain and reduced function over weeks must be weighed against the likelihood of success. Considering non-ablative approaches, pulsed dye lasers can be used for a selective, non-bloody destruction of extragenital and genital warts and may become the treatment of choice. In prospective randomized studies, they produced cure rates of up to 82% for therapy-resistant warts with few side effects. PMID:18214400

    2000-01-01

    Many depressed patients experience only limited improvement despite provision of appropriate therapies within a collaborative treatment arrangement (the integrated provision of psychotherapy and pharmacotherapy). In the interest of enhancing these patients' partial responses, it is valuable to examine the treatments provided and also the collaborative framework in which they are offered. The authors use vignettes to illustrate how each of several factors—the adequacy of treatment with each modality, behavioral impediments to response, compliance with treatments, recognition and appropriate matching of treatments to relevant concurrent diagnoses, and appropriate communication between collaborating clinicians—may affect treatment outcome. Recommendations are offered for clinicians engaging in a collaborative relationship, including attending carefully to the patients' comments about a complementary modality of treatment and the clinician delivering it, communicating useful information to the collaborating therapist, and being receptive to information that is offered by the collaborating therapist.

    Achalasia is a rare esophageal motility disorder, characterized by impaired swallow-induced, lower esophageal sphincter (LES) relaxation and defective esophageal peristalsis. Unfortunately, there are no etiological therapies for achalasia. Patients present with dysphagia, chest pain and regurgitation of undigested food, often leading to weight loss. The currently available treatments have the common aim of relieving symptoms by decreasing the pressure of the LES. This can be achieved with some medications, by inhibiting the cholinergic innervation (botulinum toxin), by stretching (endoscopic dilation) or cutting (surgery) the LES. Recently, other therapeutic options, including per-oral endoscopic myotomy have been developed and are gaining international consensus. The authors report on the benefits and weaknesses of the different therapies and provide an updated approach to the management of achalasia. PMID:26186641

    Pedophilia is a frequent cause of infringement of children's sexual integrity. It's a widely spread deviant pattern of sexual arousal and behavior, which seems to be deeply rooted in human nature, as shown by impressive ethological and cultural historical evidence. Aetiology and pathogenesis of pedophilia are still not clarified, but there is a number of interesting findings suggesting multifactorial developmental disorder as the basis of pedophilia. Regarding the treatment of pedophiles, there is usually drawn a distinction between somatic and non-somatic methods. The latter aim at relapse-prevention by augmentation of self-control. The former mean drive-reduction on a hormonal basis. Antiandrogens, progestogens and LHRH-agonists have proven themselves as having significant effects on sexual drive, whereas their side effects are quite tolerable on the whole.

    Busl, Katharina M; Bleck, Thomas P

    2012-01-01

    Bioterrorism is defined as the intentional use of biological, chemical, nuclear, or radiological agents to cause disease, death, or environmental damage. Early recognition of a bioterrorist attack is of utmost importance to minimize casualties and initiate appropriate therapy. The range of agents that could potentially be used as weapons is wide, however, only a few of these agents have all the characteristics making them ideal for that purpose. Many of the chemical and biological weapons can cause neurological symptoms and damage the nervous system in varying degrees. Therefore, preparedness among neurologists is important. The main challenge is to be cognizant of the clinical syndromes and to be able to differentiate diseases caused by bioterrorism from naturally occurring disorders. This review provides an overview of the biological and chemical warfare agents, with a focus on neurological manifestation and an approach to treatment from a perspective of neurological critical care.

    Headache is the most common complaint encountered in clinical practice. Approximately 45 million people in the United States experience chronic headaches. The management of migraine headache involves both pharmacologic and nondrug therapy. Drug therapy for migraine involves the use of abortive and prophylactic agents. Abortive agents, such as ergotamine tartrate and ketoprofen, may be used to relieve the acute attack. Prophylactic therapy is focused on reducing the frequency and severity of the attacks. beta-Adrenergic blocking agents, such as propranolol, remain the primary agents for many migraine patients, although other drugs, such as nonsteroidal anti-inflammatory drugs (NSAIDs), including ketoprofen, or calcium-channel blocking agents, such as verapamil, may be beneficial for many patients. For cluster headache and its variants, methysergide and corticosteroids are usually the drugs of choice. Patients with chronic cluster headache may achieve good results from long-term treatment with other therapies, including lithium carbonate, verapamil, and ketoprofen. PMID:2520442

    1992-01-01

    In locations where total solar energy inputs average 400 langeleys or more, microscopic algae, grown in properly designed ponds, can contribute significantly and economically to wastewater treatment. While growing, microalgae produce an abundance of oxygen for microbial and biochemical oxidation of organics and other reduced compounds and for odor control. Microalgae also accelerate the inactivation of disease bacteria and parasitic ova by increasing water temperature and pH. Microalgae remove significant amounts of nitrogen and phosphorus and adsorb most polyvalent metals, including those that are toxic. After growth in properly designed paddle wheel mixed high rate ponds, microalgae settle readily, leaving a supernatant free of most pollutants. Such effluents are suitable for irrigation of ornamental plants, crops not eaten raw, aquaculture, and grounwater recharge. The settled and concentrated microalgae may be used for fertilizer, for fermentation to methane, or, assuming no toxicity, for fish, bivalve, or animal feed.

    The principal goal of behavior treatment for retarded clients is that of modifying behavior as it occurs in a given environment in such a manner that it becomes more appropriate to that environment. The therapeutic or change agents can involve a variety of persons other than the counselor, teacher, and client--this may include parents, peers, work supervisors and others who can provide supportive influences. Education and rehabilitation programs should be tailored to the occupational and social environment of the retarded client and designed to teach those behavior patterns that are relevant to that environment. Additionally, the work tasks for which retarded clients are trained should be highly structured and routine. Excessive demand for adaptability or decision making is a major cause of training failure for retarded clients.

    The final products of the ethanol industry are alcoholic beverages, industrial ethanol and biofuels. They are produced by the same production process, which includes fermentation and distillation of raw materials which come from plant biomass. At the end of the distillation process a waste effluent is obtained called vinasse or stillage. The direct disposal of stillages on land or in groundwater (rivers, streams or lakes), or even for the direct irrigation of crops, pollutes the environment due to their high organic contents, dissolved solids and many other compounds which are toxic or could be contaminants under certain environmental conditions. This work reviews the characterization of vinasses from different feedstock sources and the main treatments for conditioning the soluble solids of vinasses before their disposal.

    An organic waste containing at least one element selected from the group consisting of strontium, cesium, iodine and ruthenium is treated to achieve a substantial reduction in the volume of the waste and provide for fixation of the selected element in an inert salt. The method of treatment comprises introducing the organic waste and a source of oxygen into a molten salt bath maintained at an elevated temperature to produce solid and gaseous reaction products. The gaseous reaction products comprise carbon dioxide and water vapor, and the solid reaction products comprise the inorganic ash constituents of the organic waste and the selected element which is retained in the molten salt. The molten salt bath comprises one or more alkali metal carbonates, and may optionally include from 1 to about 25 wt.% of an alkali metal sulfate.

    Depressions are the most common psychiatric diseases. For treatment, plant extracts have been used for thousands of years: examples are extracts from the (sleeping) poppy (opium), deadly nightshade (Atropa belladonna), Indian hemp (hashish), henbane (hyoscyamine), thorn apple (scopolamine), and St. John's wort (hypericum oil). In addition, psychotherapeutic measures, like playing music, dancing, playing theatre, and also the temple sleep, were used. In the 19th century, the introduction of brome (1826), codeine (1832), chloral hydrate (1869), and paraldehyde (1882), as well as the barbiturates (at the turn of the century) introduced significant improvements in pharmacotherapy. The modern thymoleptica therapy started in 1957 with the introduction of imipramine. Now about 40 active antidepressants are marketed. New drug developments should be characterized mainly by an improvement in tolerance.

    Chagas' disease (ChD), caused by the protozoa Trypanosoma cruzi (T. cruzi), was discovered and described by the Brazilian physician Carlos Chagas in 1909. After a century of original description, trypanosomiasis still brings much misery to humanity and is classified as a neglected tropical disease prevalent in underdeveloped countries, particularly in South America. It is an increasing worldwide problem due to the number of cases in endemic areas and the migration of infected subjects to more developed regions, mainly North America and Europe. Despite its importance, chronic chagas cardiomyopathy (CCC) pathophysiology is yet poorly understood, and independently of its social, clinical, and epidemiological importance, the therapeutic approach of CCC is still transposed from the knowledge acquired from other cardiomyopathies. Therefore, the objective of this review is to describe the treatment of Chagas cardiomyopathy with emphasis on its peculiarities. PMID:24350293

    Epistaxis is one of the most common ENT emergencies and highly prevalent in the general population. Most cases are self-limiting and patients do not usually seek medical attention. However, some cases can be severe and life-threatening. While most anterior bleeds can be effectively managed by simple measures, including pressure application, vasoconstrictive agents and cautery, some will require additional measures such as nasal packing. Posterior epistaxis can be difficult to control. Latest studies showed that surgical ligation of the sphenopalatine and/or anterior ethmoidal arteries is the most effective treatment and less painful and distressing than nasal packing. But packing is the therapeutic option that is readily available. PMID:26331200

    The effects of microbial fouling on treatment bed (TB) performance are being studied. Fouling of activated carbon (AC) and ion exchange resins (IEX) by live and devitalized bacteria can cause decreased capacity for selected sorbates with AC and IEX TB. More data are needed on organic species removal in the trace region of solute sorption isotherms. TB colonization was prevented by nonclassical chemical disinfectant compositions (quaternary ammonium resins) applied in suitable configurations. Recently, the protection of carbon beds via direct disinfectant impregnation has shown promise. Effects (of impregnation) upon bed sorption/removal characteristics are to be studied with representative contaminants. The potential need to remove solutes added or produced during water disinfection and/or TB microbiological control must be investigated.

About all the other kinds of alopecia, recommendations for therapy are still based upon the literature review, expert opinion, personal experience, expected adverse effects, and some pragmatic considerations such as the cost and the patient's compliance. Cicatricial alopecia is one of the most difficult challenges for dermatologists, because it is uncommon, its etiopathogenesis is not completely understood and there is no best therapy approach. Moreover, in Italy, most of the drugs mentioned below are not always available. Finally, therapies for hair disorders are long treatment and not always lead to a good improvement. PMID:24566570

    Growth hormone (GH) hypersecretion leads to acromegaly which is associated with several co-morbidities and increased mortality. Despite of the typical clinical features and modern diagnostic tools, it often takes years from the onset of the disease until the diagnosis. The aims of the treatment are to reduce or control the tumor growth, inhibit the GH hypersecretion, normalize the insulin-like growth factor-I (IGF-I) levels, treat the co-morbidities and therefore reduce mortality. There are three approaches for therapy: surgery, medical management (dopamine agonist, somatostatin analogues and GH receptor antagonist), and radiotherapy. Efficient therapy of the disease is based on the appropriate multidisciplinary team management. PMID:20705553

    2012-01-01

    Dermatological diseases, such as dysesthesia syndromes, stasis dermatoses, and hyperhidrosis are difficult to treat due to their complex etiologies. Current theories suggest these diseases are caused by physiological imbalances, such as nerve impingement, localized tissue congestion, and impaired autonomic regulation. Osteopathic manipulative therapy targets these physiological dysfunctions and may serve as a beneficial therapeutic option. Osteopathic manipulative therapy techniques include high velocity low amplitude, muscle energy, counterstrain, myofascial release, craniosacral, and lymphatic drainage. An osteopathic manipulative therapy technique is chosen based on its physiological target for a particular disease. Osteopathic manipulative therapy may be useful alone or in combination with standard therapeutic options. However, due to the lack of standardized trials supporting the efficacy of osteopathic manipulative therapy treatment for dermatological disease, randomized, well-controlled studies are necessary to confirm its therapeutic value.

    The process of formation of new vessels from pre-existing capillaries is called angiogenesis. Angiogenesis is a complex process which involves distinct cells, soluble components and factors related to the extra-cellular matrix and which is highly important in a large variety of physiological and pathological processes in the body. Angiogenesis regulation takes place through a perfect equilibrium between the production and release of different stimulatory and inhibitory factors which vary in relation to needs and tissue types. A large number of diseases are characterized by alterations in the angiogenic process, either by an insufficiency or by excessive angiogenesis. The requirement of blood vessel proliferation for tumor growth was observed more than a century ago. Angiogenic treatment would have an indirect antitumoral action, inhibiting tumor vascularization and impairing the supply of essential nutrients for tumoral growth and development.

    The long-term objective of this work is to develop a transformational energy production technology by insitu thermal treatment of a coal seam for the production of substitute natural gas (SNG) while leaving much of the coal's carbon in the ground. This process converts coal to a high-efficiency, low-GHG emitting gas fuel. It holds the potential of providing environmentally acceptable access to previously unusable coal resources. This topical report discusses the development of experimental capabilities, the collection of available data, and the development of simulation tools to obtain process thermo-chemical and geo-thermal parameters in preparation for the eventual demonstration in a coal seam. It also includes experimental and modeling studies of CO2 sequestration.

    The prevalence of müllerian malformations is 1 in 200, or 0.5%. A third of the anomalies are septate, a third bicornuate uteri, 10% arcuate uterus, 10% didelphis and unicornuate uterus, and < 5% uterine and vaginal aplasia. Correct diagnosis of the malformation is most important but often very difficult. Correct treatment can only be performed if the malformation is clear. Longitudinal vaginal septums have to be removed due to potential obstetric problems. Transverse vaginal septums can cause hematocolpos and pain and have to be incised crosswise and excised so as not to shorten the vagina at the same time. Congenital vaginal agenesis occurs in Mayer-Rokitansky-Kuster-Hauser syndrome patients and in androgen insensitivity syndrome. The first choice for surgical treatment should be the new laparoscopic-assisted creation of a neovagina. Septate uterus has to be distinguished from a bicornuate uterus. Even if it is not proven to be a cause for infertility, the chance of miscarriage can be diminished by performing hysteroscopic metroplasty. Repair of a uterine septum in infertility patients often improves pregnancy rates. In contrast, surgical repair of a bicornuate uterus requires an abdominal metroplasty. This should only be performed if the patient has recurrent fetal loss due to the uterine structural defect. In a unicornuate uterus it is most important to determine if there is a second uterine horn that can cause cyclic pain if it has functioning endometrium. The only surgical option in these cases is to remove the rudimentary uterus with endometrium and hematometra, respectively.

    Diagnosis of arsenicosis relies on both clinical and laboratory criteria, but principally it can be diagnosed on the basis of its cutaneous manifestations. Cutaneous manifestations (melanosis, keratosis, and cutaneous cancers) are essential clues in the diagnosis, and trained dermatologists or arsenic experts are able to clinically confirm a case even without laboratory backup. Although systemic manifestations are not considered as diagnostic hallmarks, yet their presence serves as important telltale signs in arriving at the diagnosis. In countries where laboratory facilities are available, measuring the level of arsenic in drinking water (consumed in the last 6 months), urine, hair, and nails is of immense value. Newer biomarkers of arsenic exposure are being explored to provide early information about arsenic intoxication, of which urinary porphyrin level, blood metallothionein have shown promising results. Controlling the problem of arsenicosis depends on various factors, of which the most important is cessation of intake of arsenic-contaminated water. Deep wells, traditional dug wells, treatment of surface water, rainwater harvesting, and removing arsenic from the contaminated water by arsenic removal plant or arsenic treatment unit are the available options for providing arsenic-free drinking water. The role of nutrition and antioxidants in preventing the onset of symptoms of arsenicosis is also of importance. Nonspecific therapies (e.g., keratolytics for hyperkeratosis) cannot also be ignored and serve as palliative measures. The persons affected need to be followed up at regular intervals to detect the onset of cancers (if any) at the earliest. Role of counseling and education should never be underestimated since absence of public awareness can undermine all efforts of mitigation measures.

  13. The treatment of malaria.

    White, N J

    1996-09-12

    Increasing drug resistance in Plasmodium falciparum and a resurgence of malaria in tropical areas have effected a change in treatment of malaria in the last two decades. Symptoms of malaria are fever, chills, headache, and malaise. The prognosis worsens as the parasite counts, counts of mature parasites, and counts of neutrophils containing pigment increase. Treatment depends on severity, age of patient, degree of background immunity, likely pattern of susceptibility to antimalarial drugs, and the cost and availability of drugs. Chloroquine should be used for P. vivax, P. malariae, and P. ovale. P. vivax has shown high resistance to chloroquine in Oceania, however. Primaquine may be needed to treat P. vivax and P. ovale to rid the body of hypnozoites that survive in the liver. Chloroquine can treat P. falciparum infections acquired in North Africa, Central America north of the Panama Canal, Haiti, or the Middle East but not in most of Africa and some parts of Asia and South America. In areas of low grade resistance to chloroquine, amodiaquine can be used to effectively treat falciparum malaria. A combination of sulfadoxine-pyrimethamine is responsive to falciparum infections with high grade resistance to chloroquine. Mefloquine, halofantrine, or quinine with tetracycline can be used to treat multidrug-resistant P. falciparum. Derivatives of artemisinin obtained from qinghao or sweet wormwood developed as pharmaceuticals in China are the most rapidly acting of all antimalarial drugs. Children tend to tolerate antimalarial drugs well. Children who weigh less than 15 kg should not be given mefloquine. Health workers should not prescribe primaquine to pregnant women or newborns due to the risk of hemolysis. Chloroquine, sulfadoxine-pyrimethamine, quinine, and quinidine can be safely given in therapeutic doses throughout pregnancy. Clinical manifestations of severe malaria are hypoglycemia, convulsions, severe anemia, acute renal failure, jaundice, pulmonary edema

    Diagnosis of arsenicosis relies on both clinical and laboratory criteria, but principally it can be diagnosed on the basis of its cutaneous manifestations. Cutaneous manifestations (melanosis, keratosis, and cutaneous cancers) are essential clues in the diagnosis, and trained dermatologists or arsenic experts are able to clinically confirm a case even without laboratory backup. Although systemic manifestations are not considered as diagnostic hallmarks, yet their presence serves as important telltale signs in arriving at the diagnosis. In countries where laboratory facilities are available, measuring the level of arsenic in drinking water (consumed in the last 6 months), urine, hair, and nails is of immense value. Newer biomarkers of arsenic exposure are being explored to provide early information about arsenic intoxication, of which urinary porphyrin level, blood metallothionein have shown promising results. Controlling the problem of arsenicosis depends on various factors, of which the most important is cessation of intake of arsenic-contaminated water. Deep wells, traditional dug wells, treatment of surface water, rainwater harvesting, and removing arsenic from the contaminated water by arsenic removal plant or arsenic treatment unit are the available options for providing arsenic-free drinking water. The role of nutrition and antioxidants in preventing the onset of symptoms of arsenicosis is also of importance. Nonspecific therapies (e.g., keratolytics for hyperkeratosis) cannot also be ignored and serve as palliative measures. The persons affected need to be followed up at regular intervals to detect the onset of cancers (if any) at the earliest. Role of counseling and education should never be underestimated since absence of public awareness can undermine all efforts of mitigation measures. PMID:19171979

  15. Treatment Resistant Hypertension.

    PubMed

    Egan, Brent M

    2015-11-05

    Treatment resistant hypertension (TRH) is defined by office blood pressure (BP) uncontrolled on ≥ 3 or controlled on ≥ 4 antihypertensive medications, preferably at optimal doses and including a diuretic. Apparent (a)TRH is used when optimal therapy, adherence, and measurement artifacts are unknown. Among treated hypertensives, ~30% of uncontrolled and 10% of controlled individuals have aTRH, with a higher prevalence in Blacks than other race-ethnicity groups. In ≥ 50% of aTRH patients, BP measurement artifacts ('office' TRH), suboptimal regimens, or suboptimal adherence are present, ie, pseudo-resistance. While patients with 'office' TRH have fewer cardiovascular events than those with 'true' TRH, no evidence confirms that patients with suboptimal regimens or adherence are spared. Averaging several office BPs obtained with an automated monitor can reduce 'office' TRH. Home or ambulatory BP monitoring can identify office resistance. Prescribing ≥ 3 different antihypertensive medication classes, eg, thiazide-type diuretic, renin-angiotensin blocker and calcium antagonist at ≥ 50% of maximum recommended doses reasonably defines optimal therapy. Intensifying diuretic therapy, eg, adding an aldosterone antagonist, is effective for many TRH patients who are volume expanded. Clinical information, hemodynamic and renin-guided therapeutics can inform other treatment options. Attention to adverse effects, medication costs, and pill burden can improve adherence and control. Patients with aTRH and suspected secondary hypertension should be evaluated. Interfering substances or medications should be discontinued. These approaches will identify or correct the problem in ~80% of aTRH patients. Referral to a hypertension specialist and newer therapeutic approaches are options for TRH patients who cannot take or do not respond to optimal therapy.

    Results of surgical treatment of 8 patients, suffering chylothorax, persisting during 1-14 months are presented. The desease have appeared also resistant to complex conservative treatment trial. This kind of treatment was conducted with simultaneous intensive preoperative preparation, surgical intervention consisted of open thoracotomy with thoracic duct suturing and ligature. The operative treatment had appeared primarily ultimately successful in 5 (62.5%) patients, and after postoperative pleurodesis conduction--in 3 (37.5%). One week of intensive conservative therapy trial with simultaneous preoperative preparation and subsequent shift to surgical intervention constitutes an optimal tactical principle in the persisting chylothorax treatment.

    Modern pharmacological treatments for anxiety disorders are safer and more tolerable than they were 30 years ago. Unfortunately, treatment efficacy and duration have not improved in most cases despite a greater understanding of the pathophysiology of anxiety. Moreover, innovative treatments have not reached the market despite billions of research dollars invested in drug development. In reviewing the literature on current treatments, we argue that evidence-based practice would benefit from better research on the causes of incomplete treatment response as well as the comparative efficacy of drug combinations and sequencing. We also survey two broad approaches to the development of innovative anxiety treatments:the continued development of drugs based on specific neuroreceptors and the pharmacological manipulation of fear-related memory. We highlight directions for future research, as neither of these approaches is ready for routine clinical use.

One product, Cellasene, containing a variety of botanicals and polyunsaturated fatty acids also appears to provide some relief from these symptoms. Although more work is needed, clearly these treatments do improve the appearance of skin in subjects with cellulite. It is quite possible, however, that synergies between both oral and topical routes may be the best intervention to ameliorate the signs and symptoms of cellulite.

This paper describes the first diversion scheme in which offenders who are suspected of having psychological difficulties are referred for psychological and psychiatric treatment before, and generally in lieu of, prosecution. It is argued that the procurator fiscal is successful in selecting suitable cases for treatment: most people referred have significant psychological difficulties but have failed to obtain appropriate assistance through the normal channels of referral.

    Electrochemical treatment is an alternative modality for tumor treatment based on the application of a low intensity direct electric current to the tumor tissue through two or more platinum electrodes placed within the tumor zone or in the surrounding areas. This treatment is noted for its great effectiveness, minimal invasiveness and local effect. Several studies have been conducted worldwide to evaluate the antitumoral effect of this therapy. In all these studies a variety of biochemical and physiological responses of tumors to the applied treatment have been obtained. By this reason, researchers have suggested various mechanisms to explain how direct electric current destroys tumor cells. Although, it is generally accepted this treatment induces electrolysis, electroosmosis and electroporation in tumoral tissues. However, action mechanism of this alternative modality on the tumor tissue is not well understood. Although the principle of Electrochemical treatment is simple, a standardized method is not yet available. The mechanism by which Electrochemical treatment affects tumor growth and survival may represent more complex process. The present work analyzes the latest and most important research done on the electrochemical treatment of tumors. We conclude with our point of view about the destruction mechanism features of this alternative therapy. Also, we suggest some mechanisms and strategies from the thermodynamic point of view for this therapy. In the area of Electrochemical treatment of cancer this tool has been exploited very little and much work remains to be done. Electrochemical treatment constitutes a good therapeutic option for patients that have failed the conventional oncology methods. PMID:23592904

    This report presents the results of a study of nonthermal treatment technologies. The study consisted of a systematic assessment of five nonthermal treatment alternatives. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The alternatives considered were innovative nonthermal treatments for organic liquids and sludges, process residue, soil and debris. Vacuum desorption or various washing approaches are considered for treatment of soil, residue and debris. Organic destruction methods include mediated electrochemical oxidation, catalytic wet oxidation, and acid digestion. Other methods studied included stabilization technologies and mercury separation of treatment residues. This study is a companion to the integrated thermal treatment study which examined 19 alternatives for thermal treatment of MLLW waste. The quantities and physical and chemical compositions of the input waste are based on the inventory database developed by the US Department of Energy. The Integrated Nonthermal Treatment Systems (INTS) systems were evaluated using the same waste input (2,927 pounds per hour) as the Integrated Thermal Treatment Systems (ITTS). 48 refs., 68 figs., 37 tabs.

    Achilles tendinopathy affects athletes, recreational exercisers and even inactive people. The pathology is not inflammatory; it is a failed healing response. The source of pain in tendinopathy could be related to the neurovascular ingrowth seen in the tendon's response to injury. The treatment of Achilles tendinopathy is primarily conservative with an array of effective treatment options now available to the primary care practitioner. If conservative treatment is not successful, then surgery relieves pain in the majority of cases. Directing a patient through the algorithm presented here will maximise positive treatment outcomes.

    Studies at the Brookhaven National Laboratory (BNL) have led to the development of a technically and economically feasible, as well as environmentally acceptable, biochemical process for detoxification of geothermal residues. For this process, selected microorganisms that live in extreme environments have served as models for the new biotechnology. Assuming a 2,500-kg/h sludge production rate, the new technology is capable of a better than 80% removal rate of toxic metals, usually in less than a 25-hour period. The process itself depends on a number of flexible parameters, allowing this technology to be tailored to specific needs of different geothermal producing regimes, such as those found in the Salton Sea and the Geysers area of California. Thus geothermal residual sludges and brines can be processed to remove only a few metals, such as arsenic and mercury, or many metals, ranging from valuable metals such as chromium, gold, and silver to radionuclides, such as radium. In some cases, combined metal removal and metal recovery processes may be cost efficient and therefore advantageous. The emerging biotechnology for the treatment of geothermal energy production wastes is versatile and offers a number of application options, which are discussed in the paper.

    Progression of normal glucose tolerance (NGT) to overt diabetes is mediated by a transition state called impaired glucose tolerance (IGT). Beta cell dysfunction and insulin resistance are the main defects in type 2 diabetes mellitus (type 2 DM) and even normoglycemic IGT patients manifest these defects. Beta cell dysfunction and insulin resistance also contribute to the progression of IGT to type 2 DM. Improving insulin sensitivity and/or preserving functions of beta-cells can be a rational way to normalize the GT and to control transition of IGT to type 2 DM. Loosing weight, for example, improves whole body insulin sensitivity and preserves beta-cell function and its inhibitory effect on progression of IGT to type 2 DM had been proven. But interventions aiming weight loss usually not applicable in real life. Pharmacotherapy is another option to gain better insulin sensitivity and to maintain beta-cell function. In this review, two potential treatment options (lifestyle modification and pharmacologic agents) that limits the IGT-type 2 DM conversion in prediabetic subjects are discussed. PMID:26464759

    Dravet syndrome is among the most challenging electroclinical syndromes. There is a high likelihood of recurrent status epilepticus; seizures are medically refractory; and patients have multiple co-morbidities, including intellectual disability, behaviour and sleep problems, and crouch gait. Additionally, they are at significant risk of sudden unexplained death. This review will focus predominantly on the prophylactic medical management of seizures, addressing both first-line therapies (valproate and clobazam) as well as second-line (stiripentol, topiramate, ketogenic diet) or later options (levetiracetam, bromides, vagus nerve stimulation). Sodium channel agents-including carbamazepine, oxcarbazepine, phenytoin and lamotrigine-should be avoided, as they typically exacerbate seizures. Several agents in development may show promise, specifically fenfluramine and cannabidiol, but they need further evaluation in randomized, controlled trials. In addition to prophylactic treatment, all patients need home-rescue medication and a status epilepticus protocol that can be carried out in their local hospital. Families must be counselled on non-pharmacologic strategies to reduce seizure risk, including avoidance of triggers that commonly induce seizures (including hyperthermia, flashing lights and patterns). In addition to addressing seizures, holistic care for a patient with Dravet syndrome must involve a multidisciplinary team that includes specialists in physical, occupational and speech therapy, neuropsychology, social work and physical medicine.

    Costochondritis, an inflammation of costochondral junctions of ribs or chondrosternal joints of the anterior chest wall, is a common condition seen in patients presenting to the physician's office and emergency department. Palpation of the affected chondrosternal joints of the chest wall elicits tenderness. Although costochondritis is usually self-limited and benign, it should be distinguished from other, more serious causes of chest pain. Coronary artery disease is present in 3 to 6 percent of adult patients with chest pain and chest wall tenderness to palpation. History and physical examination of the chest that document reproducible pain by palpation over the costal cartilages are usually all that is needed to make the diagnosis in children, adolescents, and young adults. Patients older than 35 years, those with a history or risk of coronary artery disease, and any patient with cardiopulmonary symptoms should have an electrocardiograph and possibly a chest radiograph. Consider further testing to rule out cardiac causes if clinically indicated by age or cardiac risk status. Clinical trials of treatment are lacking. Traditional practice is to treat with acetaminophen or anti-inflammatory medications where safe and appropriate, advise patients to avoid activities that produce chest muscle overuse, and provide reassurance.

    This paper discusses the development of a solid waste treatment system that has been designed for a Mars transit exploration mission. The technology described is an energy-efficient lyophilization technique that is designed to recover water from spacecraft solid wastes. Candidate wastes include feces, concentrated brines from water processors, and other solid wastes that contain free water. The system is designed to operate as a stand-alone process or to be integrated into the International Space Station Waste Collection System. In the lyophilization process, water in an aqueous waste is frozen and then sublimed, separating the waste into a dried solid material and liquid water. The sublimed water is then condensed in a solid ice phase and then melted to generate a liquid product. In the subject system the waste solids are contained within a 0.2 micron bio-guard bag and after drying are removed from the system and stored in a secondary container. This technology is ideally suited to applications such as the Mars Reference Mission, where water recovery rates approaching 100% are desirable but production of CO2 is not. The system is designed to minimize power consumption through the use of thermoelectric heat pumps. The results of preliminary testing of a prototype system and testing of the final configuration are provided. A mathematical model of the system is also described.

    Mandibular prognathism (MP) or skeletal Class III malocclusion with a prognathic mandible is one of the most severe maxillofacial deformities. Facial growth modification can be an effective method of resolving skeletal Class III jaw discrepancies in growing children with dentofacial orthopedic appliances including the chincup, face mask, maxillary protraction combined with chincup traction and the Fränkel functional regulator III appliance. Orthognathic surgery in conjunction with orthodontic treatment is required for the correction of adult MP. The two most commonly applied surgical procedures to correct MP are sagittal split ramus osteotomy (SSRO) and intraoral vertical ramus osteotomy. Both procedures are suitable for patients in whom a desirable occlusal relationship can be obtained with a setback of the mandible, and each has its own advantages and disadvantages. In bilateral SSRO, the intentional ostectomy of the posterior part of the distal segment can offer long-term positioned stability. This may be attributable to reduction of tension in the pterygomasseteric sling that applies force in the posterior mandible. While various environmental factors have been found to contribute to the development of MP, heredity plays a substantial role. The relative contributions of genetic and environmental components in the etiology of MP are unclear. The recent identification of the genetic susceptibilities to MP constitutes the first step toward understanding the molecular pathogenesis of MP. Further studies in molecular biology are needed to identify the gene-environment interactions associated with the phenotypic diversity of MP and the heterogenic developmental mechanisms thought to be responsible for them.

    Operative intervention should be avoided, whenever possible, by adopting a preventive approach. Timely management of early caries can lead to arrest and possibly remineralization of the lesion rendering operative intervention unnecessary. The dentist must judge when the tooth tissue has become sufficiently demineralized to allow bacterial ingress leading to irreversible changes in the tissue. Once a decision has been made to restore a tooth, the clinician must decide, from a series of traditional operative treatment options, what materials should be used in the restoration and what preparation will achieve good retention and best preservation of tooth structure. With the development of new adhesive materials and a more conservative approach, a new era of minimally invasive dentistry has dawned. Improvements in the properties of composite materials have made them the choice for coronal aesthetic restorations: for posterior restorations involving load-bearing occlusal surfaces, amalgam is still the most commonly used material in UK dental practice; glass ionomer materials also have a place in minimally invasive dentistry--patterns of use differing in different counties. The numbers of studies investigating minimal caries removal are relatively limited; there are still scope and need for research in this field.

    1. The treatment of osteoarthritis is currently purely symptomatic. To enable rational therapy, careful clinical assessment is necessary to identify the origin of symptoms. Often, effective therapy can result from a biomechanical approach such as surgery, orthotics, physiotherapy and dieting. If drugs are required, there is little evidence that the current over-reliance on non-steroidal anti-inflammatory drugs (NSAIDs) is justified. Full dose regular paracetamol should be the first line of analgesic therapy. In the majority of patients, simple analgesics are probably as effective as NSAIDs. If NSAIDs are used it is necessary to review regularly their use and to be aware of potential toxicity. 2. Many alternative strategies of pain management such as topical preparations, intra-articular steroid injections, acupuncture, radiosynovectomy, transcutaneous nerve stimulation and anti-depressants, may be effective but their precise place in the armamentarium is not yet fully established. 3. The realisation that osteoarthritis is not a passive 'wear and tear' phenomenon but an active process that may be potentially modified, has led to interest in 'chondroprotective' agents, which may beneficially affect the osteoarthritic process. To date there are no convincing data available that such agents are, in fact, chondroprotective in humans. PMID:1576063

    Liver fibrosis is the progressive deposition of extracellular matrix in the liver parenchyma that precedes the development of cirrhosis. In the last few years, knowledge of the cellular and molecular bases of liver fibrosis has increased considerably. Environmental and genetic factors have been described that influence the progression of liver fibrosis, while non-invasive methods have been developed that allow the grade of fibrosis to be estimated without the need for liver biopsy. Currently, the only clearly effective treatment to attenuate or reverse liver fibrosis is elimination of the causative agent. When this is not feasible, fibrogenic factors (such as insulin resistance, obesity, alcohol intake, cannabis consumption, etc.) should be identified and treated. However, several agents are able to reduce liver fibrosis in experimental models of chronic liver damage. Few controlled clinical trials have been performed that evaluate the efficacy and safety of these agents and consequently the level of evidence supporting their use as anti-fibrogenic therapy is still low. The efficacy of the anti- fibrogenic drugs, renin-angiotensin system inhibitors, is currently being evaluated.

    Treatment of Madelung's deformity is still controversial. We reviewed retrospectively 19 patients with Madelung's deformity (two bilateral, 21 cases) who underwent surgery to the radius and ulna to improve range of motion, decrease pain and improve appearance of the wrist. Nineteen patients underwent 21 distal radial osteotomy procedures using three different techniques: subtraction, addition or dome osteotomy. Ulnar shortening and redirection of the distal ulna was performed in 12 cases; a long oblique osteotomy was used in 10 of these cases. The Sauvé-Kapandji technique was performed in five cases, an ulnar distal epiphysiodesis in two cases and a combination of osteotomy and epiphysiodesis in one case. The aim was to reduce the distal radial slope and to restore the orientation and congruity of the distal radio-ulnar joint and to improve its function. Pain was reduced as a result of the procedure: more than 75% of the cases had no or intermittent pain at the review. Pronation improved from 63° to 68° (P=0.467, not significant) and supination improved from 48° to 72° on average (P=0.034, significant). Grip strength increased from 11 to 18 kgf (P=0.013, significant). Madelung's deformity is not always a benign condition and it responds well to corrective osteotomies. PMID:26525609

    The experience of chronic pain is one of the commonest reasons for seeking medical attention, being a major issue in clinical practice. While pain is a universal experience, only a small proportion of people who felt pain develop pain syndromes. In addition, painkillers are associated with wide inter-individual variability in the analgesic response. This may be partly explained by the presence of single nucleotide polymorphisms in genes encoding molecular entities involved in pharmacodynamics and pharmacokinetics. However, uptake of this information has been slow due in large part to the lack of robust evidences demonstrating clinical utility. Furthermore, novel therapies, including targeting of epigenetic changes and gene therapy-based approaches are further broadening future options for the treatment of chronic pain. The aim of this article is to review the evidences behind pharmacogenetics (PGx) to individualize therapy (boosting the efficacy and minimizing potential toxicity) and genes implicated in pain medicine, in two parts: (i) genetic variability with pain sensitivity and analgesic response; and (ii) pharmacological concepts applied on PGx.

    Food anaphylaxis is now the leading known cause of anaphylactic reactions treated in emergency departments in the United States. It is estimated that there are 30 000 anaphylactic reactions to foods treated in emergency departments and 150 to 200 deaths each year. Peanuts, tree nuts, fish, and shellfish account for most severe food anaphylactic reactions. Although clearly a form of immunoglobulin E-mediated hypersensitivity, the mechanistic details responsible for symptoms of food-induced anaphylaxis are not completely understood, and in some cases, symptoms are not seen unless the patient exercises within a few hours of the ingestion. At the present time, the mainstays of therapy include educating patients and their caregivers to strictly avoid food allergens, to recognize early symptoms of anaphylaxis, and to self-administer injectable epinephrine. However, clinical trials are now under way for the treatment of patients with peanut anaphylaxis using recombinant humanized anti-immunoglobulin E antibody therapy, and novel immunomodulatory therapies are being tested in animal models of peanut-induced anaphylaxis.

    Esophageal rupture is a potentially mortal condition. Rapid and correct diagnosis, and urgent surgical treatment with esophagectomy is indicated, but conservative and other surgical treatments have also been reported recently. The treatment strategies for esophageal rupture are discussed here, based on our experiences with four cases during the last 10 years. They were admitted urgently and each was treated by a different method. Three of them underwent emergency operations, one undergoing primary closure of the ruptured esophagus, another received a T-tube insertion from the ruptured site with omental flap, and the third an esophagogastrectomy. The fourth case was treated conservatively. All patients survived and were discharged 36-144 days post treatment. One of them was readmitted for debridement of necrotic rib. In conclusion, the prompt and accurate diagnosis of esophageal rupture is crucial for a subsequent successful treatment. Conservative treatment or operation including esophagectomy will be determined by the severity of the condition.

    Rosacea is a chronic inflammatory skin condition that negatively impacts patients' quality of life. We sought to review important aspects of the pathogenesis of rosacea and the role of new treatment options in its management. New, emerging treatments show promise; however, quality randomized controlled trials for many of these drugs are lacking. Brimonidine tartrate is an effective newly approved treatment for erythematotelangiectatic rosacea. Topical oxymetazoline has potential for the treatment of erythematotelangiectatic rosacea, with efficacy described in case reports and randomized controlled trials currently underway. Both oral and topical ivermectin have been studied for the treatment of papulopustular rosacea, both showing benefit; however, only topical ivermectin 1 % cream has been studied in randomized controlled trials. As our understanding of the etiology of rosacea continues to evolve, so will our options for therapeutic interventions. Further studies need to be performed to assess the long-term safety and efficacy of these treatments.

    In patients with agenesis or enamel anomalies in anterior teeth combined orthodontic and restorative treatment is often necessary to achieve an optimal aesthetic result. How both can best be achieved, but also how to maintain the result, requires communication between the dentist and the orthodontist. The orthodontic treatment plan needs to be established in cooperation with the dentist who will carry out the restorative treatment while the patient is at a young age. Since with these young patients, who are still growing craniofacially and whose teeth are still developing, possible future restorative and/or orthodontic treatment, as well as the means of orthodontic retention, need to be included in the treatment plan. In cleft palate patients, it is also important that methods of orthodontic retention of maxillary arch width are given timely attention in the restorative treatment plan because it is especially vulnerable to relapse.

    In this review we have described the rationale for the appropriate treatment of patients with Graves' disease. Because the etiology of this disorder remains obscure, its management remains controversial. Since antithyroid drugs and radioiodine became readily available in the early 1950s, they have been widely used for the treatment of thyrotoxicosis, and the number of cases treated surgically has markedly decreased. However, almost four decades of experience have disclosed an unexpectedly high incidence of delayed hypothyroidism after radioiodine treatment and a low remission rate after antithyroid therapy. As a result, surgery is again being advocated as the treatment of choice. The three modalities of treatment have different advantages and disadvantages, and selection of treatment is of importance. In principle, we believe that for most patients a subtotal thyroidectomy should be performed after the patient has been rendered euthyroid by antithyroid drugs. We attempt to leave a thyroid remnant of 6 to 8 gm.36 references.

    Esophageal rupture is a potentially mortal condition. Rapid and correct diagnosis, and urgent surgical treatment with esophagectomy is indicated, but conservative and other surgical treatments have also been reported recently. The treatment strategies for esophageal rupture are discussed here, based on our experiences with four cases during the last 10 years. They were admitted urgently and each was treated by a different method. Three of them underwent emergency operations, one undergoing primary closure of the ruptured esophagus, another received a T-tube insertion from the ruptured site with omental flap, and the third an esophagogastrectomy. The fourth case was treated conservatively. All patients survived and were discharged 36-144 days post treatment. One of them was readmitted for debridement of necrotic rib. In conclusion, the prompt and accurate diagnosis of esophageal rupture is crucial for a subsequent successful treatment. Conservative treatment or operation including esophagectomy will be determined by the severity of the condition. PMID:15209751

    Pharmacogenetics is the study of how genes (individual genotypes) affect a persons response to drugs. At present, recommendations made about the treatment of some monogenic forms of diabetes are based on genetic diagnostics. The first studies in the field of pharmacogenetics of oral antidiabetics have now been published which have identified associations of individual genetic variants with response to treatment. The response to sulfonylurea derivatives was significantly associated with the variants KCNJ11/ABCC8, TCF7L2 and CYP2C9. The response to metformin treatment was associated with the genetic variants ATM and SLC47A1. The response to treatment with glitazones was associated with the genetic variant PPARG. The therapeutic response to the treatment with gliptins was associated with the genetic variants TCF7L2 and CTRB1/2. It may be expected that in the near future pharmacogenetic knowledge will also be used within personalized treatment of type 2 diabetes. PMID:27180666

    After the diagnosis of transsexuality is well definated and recognized in most western countries, the surgical transformation of the genital area is performed. Before surgical treatment an exact psychiatric clarification is absolutely essential. The operation is the last part of a long treatment. The surgical result in the more common female transsexual is quite reasonable. The treatment of the fewer male transsexuals is not solved completely, especially the reliable techniques for penis reconstructions are not very sufficient.

    Objective To review the efficacy of current treatment options for adults with obstructive sleep apnea (OSA). Methods Review of the literature. Results OSA, characterized by repetitive ≥ 10-second interruptions (apnea) or reductions (hypopnea) in airflow, is initiated by partial or complete collapse in the upper airway despite respiratory effort. When left untreated, OSA is associated with comorbid conditions, such as cardiovascular and metabolic diseases. The current “gold standard” treatment for OSA is continuous positive air pressure (CPAP), which pneumatically stabilizes the upper airways. CPAP has proven efficacy and potential cost savings via decreases in health comorbidities and/or motor-vehicle crashes. However, CPAP treatment is not well-tolerated due to various side effects, and adherence among OSA subjects can be as low as 50% in certain populations. Other treatment options for OSA include improving CPAP tolerability, increasing CPAP adherence through patient interventions, weight loss/exercise, positional therapy, nasal expiratory positive airway pressure, oral pressure therapy, oral appliances, surgery, hypoglossal nerve stimulation, drug treatment, and combining 2 or more of the aforementioned treatments. Despite the many options available to treat OSA, none of them are as efficacious as CPAP. However, many of these treatments are tolerable, and adherence rates are higher than those of the CPAP, making them a more viable treatment option for long-term use. Conclusion Patients need to weigh the benefits and risks of available treatments for OSA. More large randomized controlled studies on treatments or combination of treatments for OSA are needed that measure parameters such as treatment adherence, apnea-hypopnea index, oxygen desaturation, subjective sleepiness, quality of life, and adverse events.

Current TB management relies on finding cases and treating them. According to Paul Nunn of WHO, the role of preventive therapy is unclear. Jensa Bell, of Mt. Sinai Hospital in New York, reported on the cost effectiveness of prevention with isoniazid (INH) in sub-Saharan Africa. Direct medical costs of the drug for 6 months are CHF171/year of life saved. When social costs of TB and prevention of secondary cases are included, INH prophylaxis saves money; initial investment is CHF34.50/person treated, while cost averted is CHF36.24/person treated. Mary Mulindwa, of the Joint Clinical Research Centre in Kampala, Uganda, studied reasons for nonadherence to TB preventive regimens in a clinical trial. Major reasons included the following: 1) transport difficulties; 2) caring for a sick family member; 3) change of address without informing the home visitor; and 4) stigma of being seen with a health worker. Richard Chaisson, of the CP-CRA004/ACTG177 study group, reported results from a trial comparing prevention with INH for 12 months to rifampin plus pyrazinamide (R/P) for 2 months in 1600 tuberculin-positive, HIV-positive people without active disease in the US, Mexico, Brazil, and Haiti. "Effective therapy" with INH was equal to at least 6 months of continuous adherence; 67% of patients met this standard. 80% of R/P patients were adherent. Over 3 years, there were 26 confirmed cases of TB in the INH group and 19 in the R/P group; these results are equivalent. However, Chaisson noted that the cost and feasibility of R/P treatment in resource-poor settings should be considered.

    Raw sewage may be presently treated by mixing screened raw sewage with activated carbon. The mixture is then allowed to stand in a first tank for a period required to settle the suspended matter to the bottom of the tank as a sludge. Thereafter, the remaining liquid is again mixed with activated carbon and the mixture is transferred to a secondary settling tank, where it is permitted to stand for a period required for the remaining floating material to settle as sludge and for adsorption of sewage carbon as well as other impurities to take place. The sludge from the bottom of both tanks is removed and pyrolyzed to form activated carbon and ash, which is mixed with the incoming raw sewage and also mixed with the liquid being transferred from the primary to the secondary settling tank. It has been found that the output obtained by the pyrolysis process contains an excess amount of ash. Removal of this excess amount of ash usually also results in removing an excess amount of carbon thereby requiring adding carbon to maintain the treatment process. By separately pyrolyzing the respective sludges from the first and second settling tanks, and returning the separately obtained pyrolyzed material to the respective first and second tanks from which they came, it has been found that the adverse effects of the excessive ash buildup is minimized, the carbon yield is increased, and the sludge from the secondary tank can be pyrolyzed into activated carbon to be used as indicated many more times than was done before exhaustion occurs.

    2013-01-01

    English Summary Hypophosphatasia (HPP) is the inborn-error-of-metabolism caused by loss-of-function mutation(s) in the gene that encodes the tissue-nonspecific isozyme of alkaline phosphatase (TNAP). The disease has been classified according to patient age when the first signs and symptoms manifest; i.e., perinatal, infantile, childhood, adult HPP. Other types include odonto HPP and perinatal benign. Babies with the perinatal/infantile forms of HPP often die with severe rickets and respiratory insufficiency and sometimes hypercalcemia and vitamin B6-responsive seizures. The primary biochemical defect in HPP is a deficiency of TNAP activity that leads to elevated circulating levels of substrates, in particular inorganic pyrophosphate (PPi), a potent calcification inhibitor. To-date, the management of HPP has been essentially symptomatic or orthopedic. However, enzyme replacement therapy with mineral-targeting TNAP (sALP-FcD10, also known as ENB-0040 or asfotase alfa) has shown promising results in a mouse model of HPP (Alpl−/− mice). Administration of mineral-targeting TNAP from birth increased survival and prevented the seizures, rickets, as well as all the tooth abnormalities, including dentin, acellular cementum, and enamel defects in this model of severe HPP. Clinical trials using mineral-targeting TNAP in children 3 years of age or younger with life-threatening HPP was associated with healing of the skeletal manifestations of HPP as well as improved respiratory and motor function. Improvement is still being observed in the patients receiving continued asfotase alfa therapy, with more than 3 years of treatment in some children. Enzyme replacement therapy with asfotase alfa has to-date been successful in patients with life-threatening HPP. PMID:25254037

    Evidence linking alcohol and other drug abuse with child maltreatment, particularly neglect, is strong. But does substance abuse cause maltreatment? According to Mark Testa and Brenda Smith, such co-occurring risk factors as parental depression, social isolation, homelessness, or domestic violence may be more directly responsible than substance abuse itself for maltreatment. Interventions to prevent substance abuse-related maltreatment, say the authors, must attend to the underlying direct causes of both. Research on whether prevention programs reduce drug abuse or help parents control substance use and improve their parenting has had mixed results, at best. The evidence raises questions generally about the effectiveness of substance abuse services in preventing child maltreatment. Such services, for example, raise only marginally the rates at which parents are reunified with children who have been placed in foster care. The primary reason for the mixed findings, say Testa and Smith, is that almost all the parents face not only substance abuse problems but the co-occurring issues as well. To prevent recurring maltreatment and promote reunification, programs must ensure client progress in all problem areas. At some point in the intervention process, say Testa and Smith, attention must turn to the child's permanency needs and well-being. The best evidence to date suggests that substance-abusing parents pose no greater risk to their children than do parents of other children taken into child protective custody. It may be sensible, say the authors, to set a six-month timetable for parents to engage in treatment and allow twelve to eighteen months for them to show sufficient progress in all identified problem areas. After that, permanency plans should be expedited to place the child with a relative caregiver or in an adoptive home. Investing in parental recovery from substance abuse and dependence, the authors conclude, should not substitute for a comprehensive approach

    Lasers in pediatric dermatology were developed as a result of the treatment of port-wine stains. Infantile hemangiomas may benefit, in some cases, from laser treatment as well as venous and lymphatic malformations. For certain pigmented lesions, as well as some hamartomas, laser treatments are a credible alternative to surgical resection. Bum scars are improved by lasers which stimulate collagen remodeling. Furthermore, hair removal of congenital and acquired hypertrichosis can relieve psychosocial discomfort and improve quality of life. The management of pain and fear of children undergoing laser treatment, using either topical or general anesthesia, remains of central importance. PMID:24772810

    These guidelines provide a review of diagnosis, conservative and surgical treatment of haemorrhoids with primary focus on the surgical treatment. In symptomatic hemorrhoids it is recommended, that conservative treatment is used as basic treatment regardless of grading. The vast majority of grade II haemorrhoids are treated conservatively, but surgery may be considered in a few cases with pronounced symptoms. In these cases chirurgia minor, Doppler guided dearterilization procedures or stapled haemorrhoidopexy are recommended. In grade III and IV Doppler guided dearterilization procedures, stapled haemorrhoidopexy (Grade III) or conventional Milligan Morgan haemorrhoidectomy are recommended.

    Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of the childhood with the highest risk of disability. Active disease persists in the adulthood in a significant portion of children with juvenile rheumatoid arthritis despite many developments in the diagnosis and treatment. Therefore, initiation of efficient treatment in the early period of the disease may provide faster control of the inflammation and prevention of long-term harms. In recent years, treatment options have also increased in children with juvenile idiopathic arthritis owing to biological medications. All biological medications used in children have been produced to target the etiopathogenesis leading to disease including anti-tumor necrosis factor, anti-interleukin 1 and anti-interleukin 6 drugs. In this review, scientific data about biological medications used in the treatment of rheumatoid arthritis and new treatment options will be discussed. PMID:26078691

    In an observational study of severely mentally ill patients treated in assertive community treatment (ACT) teams, we investigated how treatment outcome was associated with demographic factors, clinical factors, and motivation for treatment. To determine psychosocial outcome, patients were routinely assessed using the Health of the Nation Outcome Scales (HoNOS). Trends over time were analyzed using a mixed model with repeated measures. The HoNOS total score was modeled as a function of treatment duration and patient-dependent covariates. Data comprised 637 assessments of 139 patients; mean duration of follow-up was 27.4 months (SD = 5.4). Substance abuse, higher age, problems with motivation, and lower educational level were associated with higher HoNOS total scores (i.e., worse outcome). To improve treatment outcome, we recommend better implementation of ACT, and also the implementation of additional programs targeting subgroups which seem to benefit less from ACT. PMID:19847646

  3. Treatment of Frontotemporal Dementia

    Boxer, Adam L.

    2016-01-01

    Opinion statement Frontotemporal dementia (FTD) encompasses a spectrum of neurodegenerative diseases with heterogeneous clinical presentations and two predominant types of underlying neuropathology. FTD typically comprises three distinct clinical syndromes: behavioral variant frontotemporal dementia (bvFTD), semantic variant primary progressive aphasia (svPPA), and nonfluent variant primary progressive aphasia (nfvPPA). FTD also frequently overlaps both clinically and neuropathologically with three other neurodegenerative syndromes: corticobasal syndrome (CBS), progressive supranuclear palsy (PSP), and amyotrophic lateral sclerosis (ALS). Each syndrome can be associated with one or more underlying neuropathological diagnoses and are referred to as frontotemporal lobar degeneration (FTLD). Although the various FTD syndromes can substantially differ in terms of clinical symptoms and underlying pathology, the symptoms can be broadly categorized into behavioral, cognitive and motor domains. Currently there are no Food and Drug Administration (FDA) approved therapies for the above syndromes except riluzole for ALS. FTD treatment strategies generally rely on off-label use of medications for symptomatic management, and most therapies lack quality evidence from randomized, placebo-controlled clinical trials. For behavioral symptoms, selective serotonin reuptake inhibitors may be effective, while case reports hint at possible efficacy with antipsychotics or antiepileptics, but use of these latter agents is limited due to concerns regarding side effects. There are no effective therapies for cognitive complaints in FTD, which frequently involve executive function, memory, and language. Motor difficulties associated with FTD may present with parkinsonian symptoms or motor neuron disease, for which riluzole is indicated as therapy. Compared to idiopathic Parkinson’s disease, FTD-related atypical parkinsonism is generally not responsive to dopamine replacement therapies, but a

    Rash, Carla J; Petry, Nancy M

    2014-01-01

    This review discusses the research evidence for psychological treatment of gambling disorder. Several treatment options for gamblers have been explored, ranging from self-help and peer support, to brief and motivational interventions, to more intensive therapy approaches. Involvement in peer support programs seems to be optimal when combined with professional treatment; however, engagement and retention in peer support is limited. Self-directed interventions appear to benefit some gamblers; however, the involvement of therapist support, either in person or by telephone, may bolster these effects and such support need not be extensive. These self-directed options reduce the barriers associated with treatment-seeking, and may reach a wider range of gamblers than professionally delivered treatments alone. Brief and motivational approaches similarly may extend treatment options to more gamblers, namely at-risk and problem gamblers and those not seeking treatment. Of more extensive therapies, no consistent benefit of one approach emerges, although cognitive–behavioral interventions have been most often applied. Overall, several treatments have been developed for gambling disorder and results are promising, but variability in findings suggests a need for further systematic evaluation. PMID:25328420

    Intense artificial light can phase-shift circadian rhythms and improve performance, sleep, and well-being during shiftwork simulations. In real shiftworkers, however, exposure to sunlight and other time cues may decrease the efficacy of light treatment, and occupational and family responsibilities may make it impractical. With these considerations in mind, we designed and tested light-treatment protocols for NASA personnel who worked on shifted schedules during two Space Shuttle missions. During the prelaunch week, treatment subjects self-administered light of approximately 10,000 lux at times of day that phase-delay circadian rhythms. Treatment continued during the missions and for several days afterward. No treatment was administered to subjects in the control group. Treatment subjects reported better sleep, performance, and physical and emotional well-being than control subjects and rated the treatment as highly effective for promoting adjustment to their work schedules. Light treatment is both feasible and beneficial for NASA personnel who must work on shifted schedules during Space Shuttle missions.

    Background Recent investigations of language gains following treatment in bilingual individuals with chronic aphasia appear to confirm early reports that not only the treated language but also the non-treated language(s) benefit from treatment. The evidence, however, is still suggestive, and the variables that may mitigate generalisation across languages warrant further investigation. Aims We set out to examine cross-language generalisation of language treatment in a trilingual speaker with mild chronic aphasia. Methods & Procedures Language treatment was administered in English, the participant’s second language (L2). The first treatment block focused on morphosyntactic skills and the second on language production rate. Measurements were collected in the treated language (English, L2) as well as the two non-treated languages: Hebrew (the participant’s first language, L1) and French (the participant’s third language, L3). Outcomes & Results The participant showed improvement in his production of selected morphosyntactic elements, such as pronoun gender agreement, in the treated language (L2) as well as in the non-treated French (L3) following the treatment block that focused on morphosyntactic skills. Speech rate also improved in English (L2) and French (L3) following that treatment block. No changes were observed in Hebrew, the participant’s L1. Conclusions Selective cross-language generalisation of treatment benefit was found for morphosyntactic abilities from the participant’s second language to his third language. PMID:20221311

    Introduction The study aims to investigate two kinds of treatment in patients suffering from irritable bowel syndrome (IBS) and consequently compares its efficacy on improving the symptoms and mental health of patients; one with just medical treatment and another through a combination of psychotherapy and medical treatment. Material and methods Applying general sampling, 50 IBS patients were selected from among those who used to refer to a Gastroenterology Clinic. After physical and mental evaluations based on ROME-II scale and SCL-90-R questionnaires, the subjects were randomly superseded into: the control group with medical treatment and, the case group with a combination of medical and psychological treatments. The acquired data were then analyzed through t-test and Mann-Whitney U-test. Results The findings show that the mental health of patients receiving cognitive behavioral therapy along with the medical treatment was higher than those of the control group at post-test level. It was observed that the therapy reduces the disability caused by IBS. Comparatively, while the cognitive therapy and medical treatments cured 80% of the patients, those receiving cognitive therapy alone showed an extensive reduction of symptoms. Conclusions Considering the role of cognitive behavioral therapy, it is therefore recommend that such patients be managed by a combined team of gastroenterologists and psychologists. PMID:22457686

    The therapeutic management of patients with osteoarthritis aims to decrease pain and inflammation, improve physical function, and to apply safe and effective treatments. A patient-centered approach implies the active participation of the patient in the design of the treatment plan and in timely and informed decision-making at all stages of the disease. The nucleus of treatment is patient education, physical activity and therapeutic exercise, together with weight control in overweight or obese patients. Self-care by the individual and by the family is fundamental in day-to-day patient management. The use of physical therapies, technical aids (walking sticks, etc.) and simple analgesics, opium alkaloids, and antiinflammatory drugs have demonstrated effectiveness in controlling pain, improving physical function and quality of life and their use is clearly indicated in the treatment of osteoarthritis. Conservative surgery and joint replacement is indicated when treatment goals are not achieved in specific patients.
