    This study aimed to analyze the effects of nandrolone decanoate on the ovaries and uterus of adult females rats. This drug was administered intraperitoneally, at one, two and three doses of 3 mg nandrolone decanoate/kg of body weight, respectively, in the first, second and third week of treatment. The females of the control group received a physiological solution. The rats treated with nandrolone decanoate showed estral acyclicity and there was destruction of follicular units and an absence of corpus luteum in the ovaries. In the uterus, the drug promoted morphological alterations, characterized by vacuolated epithelium and endometrial stroma fibrosis. Ovary, uterus and pituitary weights were not affected by the steroid treatment. Nandrolone decanoate affects the sexual cycle and promotes histological alterations in the ovaries and uterus of adult female rats.

    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.

    Nandrolone decanoate (Deca-Durabolin) was injected intramuscularly into healthy volunteers. One group of females received one injection of 100 mg and three groups of males received one injection of 200 mg, two repeat injections of 100 mg or four repeat injections of 50 mg respectively. The serum levels of nandrolone (19-nortestosterone) were determined by radioimmunoassay and used to estimate pharmacokinetic parameters. The following pharmacokinetic parameters were found: a mean half-life of 6 days for the release of the ester from the muscular injection depot into the general circulation; a mean half-life of 4.3 h for the combined processes of hydrolysis of nandrolone decanoate and of distribution and elimination of nandrolone; a mean nandrolone serum clearance of 1.55 1 X h-1 X kg-1. The half-life of hydrolysis of nandrolone decanoate in serum was of the order of one hour or less. The data are consistent with linear kinetics.

    Supratherapeutical doses of anabolic androgenic steroids (AASs) have dramatic effects on metabolism in humans, and also inhibit feeding and reduce the rate of body weight gain in rats. In order to test the hypothesis that the AAS metabolic syndrome is accompanied by alterations in the central melanocortin system, we evaluated body weight, food intake and hypothalamic agouti-related protein (AgRP) and proopiomelanocortin (POMC) mRNA levels following administration of different doses of the anabolic androgenic steroid nandrolone decanoate. In order to distinguish changes induced by the steroid treatment per se from those resulting from the reduced food intake and growth rate, we also compared the effect of nandrolone decanoate on AgRP and POMC mRNA expression with both normally fed, and food restricted control groups. We here report that administration of nandrolone specifically reduces arcuate nucleus POMC mRNA levels while not affecting the expression level of AgRP. The effect on POMC expression was not observed in the food restricted controls, excluding the possibility that the observed effect was a mere response to the reduced food intake and body weight. These results raise the possibility that some of the metabolic and behavioural consequences of AAS abuse may be the result of alterations in the melanocortin system.

    The anabolic androgenic steroid nandrolone decanoate has minimal androgenic effects and, thus, is widely used to induce muscle hypertrophy in both patients and athletes. Although increases in satellite cell numbers and satellite cells giving rise to new myonuclei are associated with hypertrophy in many experimental models, the relationship between nandrolone and satellite cells is poorly understood. Here we test the hypothesis that nandrolone administration is associated with an increase in satellite cell numbers in muscle. Nandrolone was injected at weekly intervals for four weeks into the right pectoralis muscle of female white leghorn chickens aged 63 days post hatch. Age/size/sex matched control birds received saline injections. The contralateral pectoralis was excised for study from each control and nandrolone treated bird. An antibody against Pax7 and immunocytochemical techniques were used to identify satellite cells. Nandrolone significantly increased mean pectoralis mass by approximately 22%, and mean fiber diameter by about 24%. All satellite cell indices that were quantified increased significantly in chicken pectoralis with administration of nandrolone. Nandrolone injected birds had on average higher satellite cell frequencies (#SC nuclei/all nuclei within basal lamina), number of satellite cells per millimeter of fiber, and satellite cell concentrations (closer together). Myonuclei were further apart (less concentrated) in nandrolone injected muscle. However, an overall increase in myonuclear numbers was revealed by a significantly greater mean number of myonuclei per millimeter of fiber in nandrolone injected muscle. Our results suggest that satellite cells may be key cellular vectors for nandrolone induced muscle fiber hypertrophy.

    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.

    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.

    Although testosterone administration elicits well-documented anabolic effects on skeletal muscle mass, the enhancement of muscle regeneration after injury has not been widely examined. The purpose of this study was to determine whether anabolic steroid administration improves skeletal muscle regeneration from bupivacaine-induced injury. Male C57BL/6 mice were castrated 2 wk before muscle injury induced by an intramuscular bupivacaine injection into the tibialis anterior (TA) muscle. Control mice received an intramuscular PBS injection. Anabolic steroid [nandrolone decanoate (ND), 6 mg/kg] or sesame seed oil was administered at the time of initial injury and continued every 7 days for the study's duration. Mice were randomly assigned to one of four treatment groups for 5, 14, or 42 days of recovery, as follows: 1) control (uninjured); 2) ND only (uninjured + ND); 3) bupivacaine only (injured); or 4) bupivacaine + ND (injured + ND). TA morphology, protein, and gene expression were analyzed at 14 and 42 days after injury; protein expression was analyzed at 5 days after injury. After 14 days of recovery, the injury and injury + ND treatments induced small-diameter myofiber incidence and also decreased mean myofiber area. The increase in small-myofiber incidence was 65% greater in injury + ND muscle compared with injury alone. At 14 days, injury + ND induced a fivefold increase in muscle IGF-I mRNA expression, which was greater than injury alone. Muscle Akt activity and glycogen synthetase kinase-3β activity were also induced by injury + ND at 14 days of recovery, but not by injury alone. ND had a main effect for increasing muscle MyoD and cyclin D1 mRNA expression at 14 days. After 42 days of recovery, injury + ND increased large-diameter myofiber incidence compared with injury only. Nandrolone decanoate (ND) administration can enhance castrated mouse muscle regeneration during the recovery from bupivacaine-induced injury. PMID:19745189

    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.

    Pre-treatment with the anabolic steroid nandrolone decanoate (ND) increases the LD50 of 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) and 5-Fluorouracil (FU) in NMRI mice. Administration of ND did not affect the anti-tumour action of CCNU against a transplantable mouse adenocarcinoma of the colon (MAC 13) or the anti-tumour action of FU against MAC 26. In both tumour lines ND had no significant effect on tumour growth. These data suggest that an increase in the anti-tumour selectivity of these agents may be produced by pre-treatment with ND.

    The aim of the present study was to examine possible long-term effects of the anabolic androgenic steroid (AAS), nandrolone decanoate (ND), on dominance in a provoking and competitive situation in sexually matured male rats. The experimental group (n=10) received daily injections of ND [15 mg/kg in a volume of 1 ml/kg subcutaneous (s.c.) injection for 14 days]. During the corresponding period, the controls (n=10) were given daily injections of an oil vehicle (1 ml/kg s.c.). All animals were tested in a competitive situation at four occasions after the end of the treatment period (week 5, 8, 11 and 14). Water-deprived pairs of rats, consisting of one ND-treated rat and one control, had to compete for access to water. The results showed that the ND-treated rats approached the water spout significantly more often compared to the controls. During the competition tests, the ND-treated rats spent more time drinking, an effect that was prominent for 11 weeks after the end of the treatment period. The ND-treated rats also displayed more frequently piloerection than the controls. The results indicate that ND has long-term effect on dominance in a provoking and competitive situation.

    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.

    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.

    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

    The abuse of anabolic androgenic steroids (AAS) may cause side effects in several tissues. Oxidative stress is linked to the pathophysiology of most of these alterations, being involved in fibrosis, cellular proliferation, tumorigenesis, amongst others. Thus, the aim of this study was to determine the impact of supraphysiological doses of nandrolone decanoate (DECA) on the redox balance of liver, heart and kidney. Wistar male rats were treated with intramuscular injections of vehicle or DECA (1 mg.100 g−1 body weight) once a week for 8 weeks. The activity and mRNA levels of NADPH Oxidase (NOX), and the activity of catalase, glutathione peroxidase (GPx) and total superoxide dismutase (SOD), as well as the reduced thiol and carbonyl residue proteins, were measured in liver, heart and kidney. DECA treatment increased NOX activity in heart and liver, but NOX2 mRNA levels were only increased in heart. Liver catalase and SOD activities were decreased in the DECA-treated group, but only catalase activity was decreased in the kidney. No differences were detected in GPx activity. Thiol residues were decreased in the liver and kidney of treated animals in comparison to the control group, while carbonyl residues were increased in the kidney after the treatment. Taken together, our results show that chronically administered DECA is able to disrupt the cellular redox balance, leading to an oxidative stress state. PMID:25225984

    The androgen nandrolone decanoate (ND) is known to cause cardiovascular abnormalities, such as attenuation of the Bezold-Jarisch Reflex (BJR), cardiac hypertrophy, and elevation of mean arterial pressure (MAP). Futhermore, a relationship between androgens and the renin-angiotensin system (RAS) has been reported. The purpose of this study was to evaluate the influence of RAS on the BJR, cardiac and prostatic hypertrophy, and MAP evoked by ND. For this, male Wistar rats were treated with ND (10 mg·(kg body mass)(-1) for 8 weeks; DECA), or vehicle (control animals; CON), or enalapril (10 mg·(kg body mass)(-1), daily; CONE), or ND and enalapril (10 mg ND + 10 mg enalapril per kilogram of body mass; DECAE). After 8 weeks of treatment, the BJR was evaluated by bradycardia and hypotensive responses that were elicited by serotonin administration (2-32 µg·(kg body mass)(-1)). MAP was assessed; cardiac and prostate hypertrophy were determined by the ratio of the tissue mass:body mass, and by histological analysis of the heart. Animals from the DECA group showed prostatic and cardiac hypertrophy, elevation in mean arterial pressure, and an impairment of BJR. Co-treatment with enalapril inhibited these changes. The data from the present study suggest that RAS has an impact on BJR attenuation, cardiac and prostatic hypertrophy, and the elevation in MAP evoked by ND.

    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

    Anabolic steroids increase appetite and muscle mass. This randomized, double-blind trial investigates any nutritional benefits of anabolic steroid in patients after surgery for esophageal cancer. Forty patients were recruited: 19 patients had five injections of 50 mg nandrolone decanoate and 21 patients received placebo over 3 months, starting 1 month after surgery. Measurements of body weight, mid-arm muscle circumference (MAMC) and appetite were taken over a 6-month period. Nutrition was optimized by dietary advice and by esophageal dilatation if required. Percent ideal weight, percent ideal MAMC and appetite score did not show significant differences between steroid and placebo groups, but there was a trend to an increase over 6 months for percent ideal MAMC in the test group. With this protocol, we have experienced minimal side-effects. However, we have not demonstrated any therapeutic benefit with low-dose steroid. An increased dose schedule over a longer period might produce a significant response.

    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.

    Long-term therapy of nandrolone (N) is recommended to increase mineral density and muscle strength. Using a parenteral sustained release drug formulation with nandrolone decanoate (ND), therapeutic N levels can be achieved and maintained. Until now, it is unknown if hydrolysis of ND into N occurs in tissue at the injection site or after systemic absorption. Therefore, hydrolysis studies were conducted to investigate the location and rate of ND hydrolysis after its release from the oil depot. ND hydrolysis was studied in porcine tissues, to mimic the human muscular and subcutaneous tissues. Additionally, the ND hydrolysis was studied in human whole blood, plasma and serum at a concentration range of 23.3-233.3μM. ND hydrolysis only occurred in human whole blood. The hydrolysis did not start immediately, but after a lag time. The mean lag time for all studied concentrations was 34.9±2.5min. Because of a slow penetration into tissue, hydrolysis of ND is found to be very low in surrounding tissue. Therefore the local generation of the active compound is clinically irrelevant. It is argued that after injection of the oil depot, ND molecules will be transported via the lymphatic system towards lymph nodes. From here, it will enter the central circulation and within half an hour it will hydrolyse to the active N compound.

    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.

    Necrophagous insects are valuable tools for postmortem interval (PMI) estimation or for determining the cause of death. Due to the increase in deaths related to drug abuse, it is crucial to know how these substances affect the development of flies that feed on corpses, to avoid errors in the PMI estimates. This study evaluated the effect of nandrolone decanoate, an anabolic androgenic steroid, on the development ofimmatures of Chrysomya megacephala (F.), Chrysomya putoria (Wiedemann), and Chrysomya albiceps (Wiedemann) (Diptera:Calliphoridae) when added to an artificial rearing diet. Four experimental groups were delineated: three of them were given diets containing 4.5, 22.5, or 45 mg/kg nandrolone decanoate; and a drug-free control group. Weights were recorded at 12-h intervals from larval eclosion to pupation. No statistically significant differences were observed in mean larval weights, emergence interval, or emergence rates for all groups. However, differences in the three species were observed during the larval development. Initially, C. putoria reared in the highest concentration of decanoate showed greater weight gain. However, at older ages, immatures reached lower mean weights than the control group. For C. albiceps, the highest concentration of decanoate contributed to an effective lack of weight gain during almost the entire course of larval development. Therefore, the influence of any drug on development should always be considered.

    The aim was to study the effect and time profile of a single dose of nandrolone decanoate (ND) on gonadotropins, blood lipids and HMG CoA reductase [3-hydroxy-3-methyl-glutaryl-CoA reductase (HMGCR)] in healthy men. Eleven healthy male participants aged 29-46 years were given a single dose of 150 mg ND as an intramuscular dose of Deca Durabol®, Organon. Blood samples for sex hormones, lipids and HMGCR mRNA analysis were collected prior to ND administration day 0, 4 and 14. A significant suppression of luteinising hormone (LH) and follicle-stimulating hormone (FSH) was seen after 4 days. Total testosterone and bioavailable testosterone level decreased significantly throughout the observed study period. A small but significant decrease in sexual hormone-binding globulin (SHBG) was seen after 4 days but not after 14 days. Total serum (S)-cholesterol and plasma (P)-apolipoprotein B (ApoB) increased significantly after 14 days. In 80% of the individuals, the HMGCR mRNA level was increased 4 days after the ND administration. Our results show that a single dose of 150 mg ND increases (1) HMGCR mRNA expression, (2) total S-cholesterol and (3) P-ApoB level. The long-term consequences on cardiovascular risk that may appear in users remain to be elucidated.

    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

    The treatment of alcoholism still presents great problems because a number of factors have to be taken into consideration. Tranquilizers and chlormethiazol are only justified in the detoxication phase. For the subsequent after-care, depot neuroleptics are recommended because of the uniformly high plasma level. We gave clopentixol decanoate - 100 mg i.m. - in two-weekly intervals. The symptoms caused by ethylism were adequately overcome without side effects. Clopentixol decanoate creates the basis for successful psychotherapy: only when the mood situation is compensated and the internal unrest overcome can verbal therapy be successful.

    Respiratory failure in patients with COPD may be caused by insufficient force production or insufficient endurance capacity of the respiratory muscles. Anabolic steroids may improve respiratory muscle function in COPD. The effect of anabolic steroids on mitochondrial function in the diaphragm in emphysema is unknown. In an emphysematous male hamster model, we investigated whether administration of the anabolic steroid nandrolone decanoate (ND) altered the activity of mitochondrial respiratory chain complexes in the diaphragm. The bodyweight of hamsters treated with ND was decreased after treatment compared with initial values, and serum testosterone levels were significantly lower in hamsters treated with ND than in control hamsters. No difference in the activity of mitochondrial respiratory chain complexes in the diaphragm between normal and emphysematous hamsters was observed. Treatment with ND did not change the activity of mitochondrial respiratory chain complexes in the diaphragm of both normal and emphysematous hamsters. In emphysematous hamsters, administration of ND decreased the activity of succinate:cytochrome c oxidoreductase compared with ND treatment in normal hamsters. We conclude that anabolic steroids have negative effects on the activity of succinate:cytochrome c oxidoreductase and anabolic status in this emphysematous hamster model. PMID:18046906

    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.

    23 schizophrenic outpatients in maintenance treatment with zuclopenthixol decanoate were included in a study aimed at finding the minimum effective dose and corresponding serum concentration of zuclopenthixol. Every three months the dose was gradually reduced until prodromal symptoms appeared, indicative of an incipient relapse. A slightly higher dose was then promptly reinstituted (the minimum effective dose). At each dose level, two blood samples were drawn to determine the serum concentration. This dose reduction principles proved feasible. Only one patient had a clear-cut relapse. The condition of the remaining patients was acceptably maintained by a dose increase. The minimum effective dose of zuclopenthixol was 200 mg/2 weeks (range 60-400), with a serum concentration of 22 nmol/l (7.1-69.7). There was a significant correlation between the administered dose and the corresponding serum level of the drug (r = 0.66, P < 0.01). A trend towards a positive correlation was found between the serum level at the minimum effective dose and the BPRS score (r = 0.42, P < 0.1). No correlation was found between the serum level and the side-effects or length of neuroleptic treatment. It is concluded that routine serum drug monitoring is hardly indicated in the long-term depot-neuroleptic treatment of schizophrenic patients. A strategy aiming at continually seeking the lowest effective dose on the basis of clinical parameters appears more appropriate, especially in case of depot-neuroleptic treatment.

    Importance Long-acting injectable (LAI) antipsychotics are used to reduce medication non-adherence and subsequent relapse in schizophrenia-spectrum disorders. The relative effectiveness of LAI versions of second-generation (atypical) and older antipsychotics has not been assessed. Objective To compare the effectiveness of the second-generation LAI antipsychotic paliperidone palmitate (PP) to the older LAI antipsychotic haloperidol decanoate (HD). Design, Setting, and Participants Multisite, double-blind, randomized clinical trial conducted at 22 clinical research sites in the U.S. The 311 randomized patients (PP=157, HD=154) were adults diagnosed with schizophrenia or schizoaffective disorder who were clinically assessed to be at risk of relapse and likely to benefit from a LAI antipsychotic. Interventions Intramuscular injections of HD 25–200 mg or PP 39–234 mg every month for up to 24 months. Main Outcome Measures Efficacy failure, which reflected inadequate control of psychopathology by the study medication, as determined by a blinded adjudication committee. Key secondary outcomes were common adverse effects of antipsychotic medications. Results There was no statistically significant difference in the rate of efficacy failure for PP compared to HD (adjusted hazard ratio 0.98, 95% confidence interval [CI] 0.65–1.47). On average, patients on PP gained and those on HD lost weight; after six months the least squares mean weight change on PP was +2.17 kg (1.25 to 3.09) and on HD was −0.96 kg (−1.88 to −0.04). Patients taking PP had significantly greater increases in serum prolactin (men 34.56 µg/L (29.75 to 39.37) vs. 15.41 (10.73 to 20.08), p<0.001; women 75.19 (63.03 to 87.36) vs. 26.84 (13.29 to 40.40), p<0.001). Patients taking HD had significantly larger increases in global ratings of akathisia (0.73 [0.59 to 0.87] vs. 0.45 [0.31 to 0.59], p=0.006).

    Anabolic androgenic steroids (AAS) are compounds formed from testosterone or one of its derivatives, which are largely used by amateur e professional athletes to improve the athletic performance. However, the scientific information about the relation between the use of AAS and muscle hypertrophy is controversial. The aim of this study was to evaluate the effects of testosterone and physical training on muscle hypertrophy. Male Wistar rats received i.m. injections of Deca-Durabolin or vehicle during 6 weeks. Trained rats were submitted to a resistance physical training, by jumping up and down in water carrying an overload. Sedentary and trained animals were anesthetized and sacrificed. Soleus muscle was removed for the quantification of total protein and DNA concentration. In the end of the treatment, body weight of trained animals treated with vehicle or AAS was lower than the body weight of respective sedentary. Total protein concentration and the ratio muscle weight/body weight of all experimental groups were not altered. Trained group treated with AAS presented lower DNA concentration than trained group treated with vehicle. The administration of nandrolone decanoate did not promote hypertrophy on soleus muscle, not even when the use of AAS was associated to resistance physical training.

    See Rogawski (doi:10.1093/awv369) for a scientific commentary on this article.  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.

    Nandrolone, an anabolic steroid, is used for the treatment of several diseases and is available in various pharmaceutical formulations. The most widely used pharmaceutical formulation is Deca-Durabolin, but other products, such as Keratyl eye drops solution, are also currently administered. Nandrolone is one of the most abused anabolic steroid in sports. Analyses for this anabolic steroid according to the World Anti-Doping Agency (WADA) protocol are based on the identification of the nandrolone two main urinary metabolites which, in humans, are glucuronides of 19-norandrosterone and 19-noretiocholanolone. A positive cut off limit of 2 ng/mL has been set by the anti-doping code for the first metabolite, 19-norandrosterone. In this preliminary study, an eye drops solution (Keratyl) containing a therapeutic dose of a nandrolone sodium sulphate was administered to several male volunteers during 3 days and urines were collected during 3 weeks. Surprisingly, contrary to all expectations, the urinary concentrations measured in urines reached 450 ng/mL and 70 ng/mL for norandrosterone and noretiocholanolone, respectively. Moreover, concentration levels near to 2 ng/mL were found, more than 2 weeks after the last administration, depending on individual metabolism. Inter-variability as well as intra-variability of nandrolone excretion kinetic, regarding this particular administration mode, were also evaluated. Quantification of nandrolone metabolites was performed by GC-MS. The method was previously validated in terms of specificity, precision, linearity, LOD, LOQ, robustness, accuracy and the expanded uncertainty was also evaluated.

    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.

    Clinical and pre-clinical observations indicate that anabolic-androgenic steroids can induce neurobiological changes that alter the rewarding effects of drugs of abuse. In this study, we investigated the effect of the anabolic steroid nandrolone on the rewarding properties of the cannabinoid CB1 receptor agonist WIN55,212-2 (WIN) in rats. Lister Hooded male rats were treated intramuscularly with nandrolone (15mg/kg) or vehicle for 14 consecutive days, and then allowed to self-administer WIN (12.5μg/kg/infusion) intravenously. After reaching stable drug intake, self-administration behavior was extinguished to examine drug- and cue-induced reinstatement of cannabinoid-seeking behavior. Other behavioral parameters presumed to influence drug-taking and drug-seeking behaviors were examined to gain more insight into the behavioral specificity of nandrolone treatment. Finally, animals were sacrificed for analysis of CB1 receptor density and function in selected brain areas. We found that nandrolone-treated rats self-administered up to 2 times more cannabinoid than vehicle-treated rats, but behaved similarly to control rats when tested for drug- and cue-induced reinstatement of cannabinoid-seeking behavior. Enhanced cannabinoid intake by nandrolone-treated rats was not accompanied by changes in locomotor activity, sensorimotor gating, or memory function. However, our molecular data show that after chronic WIN self-administration nandrolone-treated rats display altered CB1 receptor density and function in selected brain areas. We hypothesize that increased cannabinoid self-administration in nandrolone-treated rats results from a nandrolone-induced decrease in reward function, which rats seem to compensate by voluntarily increasing their cannabinoid intake. Altogether, our findings corroborate the hypothesis that chronic exposure to anabolic-androgenic steroids induces dysfunction of the reward pathway in rats and might represent a potential risk factor for abuse of

    Abscisic acid (ABA) and decanoic acid inhibited shoot elongation and floral development of Dutch iris (Iris hollandica Hoog. cv Ideal) meristems cultured in vitro. No synergism with respect to inhibition of leaf growth between ABA and decanoic acid was observed. With monthly harvest dates, from July 10, 1981 to October 10, 1981, there was a progressive decrease in endogenous level of free ABA in `Ideal' iris bulbs. Bulbs subjected to a full set of the usual preplanting storage conditions flowered, on average, 46 days after planting versus 194 days after planting for bulbs planted directly after harvest. ABA levels at harvest were 4- to 5-fold those after the preplanting storage treatment. In general, ABA levels did not correlate well with the length of time from planting until flowering of iris bulbs. Endogenous decanoic acid levels did not follow any pattern with respect to harvest date or postharvest treatment. After the postharvest high temperature treatment, there was about a 3-fold increase in nonscale decanoic acid concentration. Decanoic acid levels, in nonscale tissue, remained high after each of the other postharvest treatments. It is concluded that there is no good evidence to support the contention that either ABA or decanoic acid is directly involved in iris bulb dormancy. PMID:16663072

We describe a patient who in the course of clinical treatment with the thioxanthene antipsychotic zuclopenthixol (Clopixol) decanoate had several episodes of priapism. Although the alpha-blocking potential of zuclopenthixol is only moderate, it seems that in sufficient dose, or in combination with other antipsychotics, this drug is capable of inducing priapism.

    To investigate whether nandrolone decanoate (ND)-pretreatment can modulate (1) beta-adrenoceptor expression and (2) myocardial contractility in response to beta-adrenoceptors stimulation with isoproterenol (ISO), in hearts of both normal and stressed rats. Rats were treated with 15 mg/(kgday) of Deca-Durabolin (ND, 1 ml i.m.) or with vehicle (oil) for 14 days. The day after the last injection, the dose-response to ISO (1 x 10(-8), 5 x 10(-8) and 10(-7)M), was studied in isolated rat hearts harvested from unstressed animals (unstressed+vehicle (control) or unstressed+ND) or from stressed animals (stressed+vehicle or stressed+ND): acute stress protocol consisted in restrain for 1h immediately before sacrifice. ND-pretreatment increased beta(2)-adrenoceptor expression. In baseline conditions all hearts had a similar left ventricular developed pressure (LVDP) and maximum rate of increase of LVDP (dP/dt(max)). In hearts of unstressed+vehicle or unstressed+ND, ISO caused a similar increase in LVDP (+90-100%) and dP/dt(max) (+120-150%). However, hearts of stressed+vehicle animals showed a marked depression of inotropic response to ISO (i.e. for ISO 1 x 10(-8),-55% in LVDP response versus unstressed). Yet, in hearts of stressed+ND-animals the effect of stress was reversed, showing the highest response to ISO (i.e. for ISO 1 x 10(-7), +30% LVDP response versus unstressed). The ND-induced beta(2)-adrenoceptor overexpression does not affect ISO-response in unstressed animals. However, acute stress induces a down-regulation of ISO-response, which is reversed by ND-pretreatment. Since the physiological post-stress down-regulation of adrenergic-response is absent after nandrolone treatment, the heart may be exposed to a sympathetic over-stimulation. This might represent a risk for cardiovascular incidents in anabolic steroid addicts under stressing conditions.

    Veterinary drugs usually have rapid clearance rates in the liver and kidney, hampering their detection in conventional matrices such as the liver or urine. Pharmacological principles such as esterification may be applied to facilitate the administration of veterinary drugs and increase drug half-life. Prednisolone, whose therapeutic administration is regulated for food producing animals in the EU, is available in its acetate form as well as nandrolone, a banned anabolic steroid, which may be obtained as nandrolone phenylpropionate and estradiol as a benzoyl ester. While the distribution and accumulation of lipophilic and hydrophilic substances in human teeth have been well documented, studies on residues in bovine teeth are lacking. We hypothesised that analysis of bovine teeth could be used to detect both regulated and banned veterinary drugs. Steroids may be illegally used as growth promoters in food producing animals, alone or combined with β2-agonists; therefore, we developed, and validated, in accordance with the Commission Decision 2002/657/EC, two analytical confirmatory LC-MS/MS methods to detect these classes of compounds following a unique liquid extraction procedure. Finally, we analysed teeth from three male Friesian veal calves treated with intramuscular estradiol benzoate, oral prednisolone acetate or intramuscular nandrolone phenylpropionate in combination with oral ractopamine, respectively, and from seven bovines from the food chain. Teeth from treated animals were positive for their respective drugs, with the exception of nandrolone phenylpropionate. One sample from a food chain bovine was positive for isoxsuprine, one of the seven β2-agonists studied. Non-esterified forms of the steroids were not found. These results demonstrate that bovine teeth are a suitable matrix for the determination of pseudoendogenous substances or illicit administration of veterinary drugs.

    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

    Wasting, and particularly loss of metabolically active lean tissue, contributes to increased mortality, accelerated disease progression, and impairment of strength and functional status in patients with HIV infection. A variety of protein anabolic agents, including growth hormone, insulin-like growth factor-I, testosterone, nandrolone decanoate, oxandrolone, and oxymetholone, have been studied in patients with HIV-associated wasting. Overall, these studies have demonstrated that treatment with protein anabolic agents can increase lean body mass (LBM) and in some cases provide functional benefits and improvements in quality of life. Further research is needed to determine whether such treatment prolongs survival or reduces the overall health care burden of HIV infection. The advances in identification of successful treatments for HIV-associated wasting can provide a model for using these therapies in other catabolic states, including end-stage renal disease, cancer, chronic obstructive pulmonary disease, and cardiac cachexia.

    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.

    The efficacy and side-effects of Deca-Durabolin (DD) were tested, in a double blind fashion, in twenty female primary Sjögren's syndrome (1 degree SS) patients. Ten randomly assigned patients received DD (100 mg IM bi-weekly) for six months, and ten others placebo, for the same period. Analysis of the results revealed that the DD-treated patients showed a moderate improvement of subjective xerostomia, a significant decrease of the erythrocyte sedimentation rate (ESR), and an overall improvement of their feeling of well-being, -judged by themselves and the investigator subjectively-, when compared with the placebo group. All the sicca objective parameters (results of Schirmer's I test, slit lamp eye examination after rose bengal staining, stimulated parotid flow rate measurements and labial minor salivary gland histopathology) were not significantly altered in either group. The clinical side-effects were the expected ones, i.e. hirsutism, hoarseness and an increase in libido, more pronounced in the DD-treated group. At the end of the study, one DD-treated patient, developed a diffuse well-differentiated B-lymphocytic lymphoma, which regressed spontaneously three months later.

    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.

    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. J. Cell.

    Under European legislation, the use of growth promoters is forbidden in food-producing livestock. The application of unofficial protocols with diverse combinations of veterinary drugs, administered in very low concentrations, hinders reliable detection and subsequent operative prevention. It was observed that nandrolone (anabolic steroid) and ractopamine (β-adrenergic agonist) are occasionally administered to animals, but little is known about their synergic action when they are administered together. Two specific analytical methods based on liquid chromatography-tandem mass spectrometry have been developed, both of which include hydrolysis of the corresponding conjugates. For the nandrolone method, solid-phase extraction was necessary for the complete elimination of the interferences, while employment of the Quantitation Enhanced Data-Dependent scan mode during MS acquisition of ractopamine enabled the utilization of simple liquid-liquid extraction. The nandrolone method was linear in the range of 0.5-25 ng/mL, while the ractopamine calibration curve was constructed from 0.5 to 1000 ng/mL. The corresponding coefficients of correlations were >0.9907. The lower limit of quantification for both methods was 0.5 ng/mL, followed by overall recoveries >81%. Precisions expressed as relative standard deviations were <17%, while matrix effects were minimal. Urine samples taken at the slaughterhouse from veal calves enrolled in an experimental treatment consisting of intramuscular administration of β-nandrolone-phenylpropionate accompanied with a ractopamine-enriched diet were analysed. Those methods might be useful for studying the elimination patterns of the administered compounds along with characterization of the main metabolic pathways. Copyright © 2016 John Wiley & Sons, Ltd.

    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.

    There has recently been renewed interest in novel clinical applications of the anabolic-androgenic steroid (AAS) testosterone and its synthetic derivatives, particularly given with the rising popularity of testosterone supplementation therapy (TST) for the treatment of male hypogonadism. In this manuscript, we provide a brief review of the history of AAS and discuss clinical applications of two of the more well-known AAS: nandrolone and oxandrolone. 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.

    Affective disorders and impulsivity are quite common when using anabolic substances, in this case-study one of the rather rare cases of a psychotic disorder following the abuse of androgenic steroids is described. A 30-year old formerly healthy white male was admitted as inpatient to psychiatric hospital showing symptoms of anxiety and paranoid ideation. In the last 1,5 years he had consumed androgenic steroids, directly before the onset of the first psychotic symptoms 8 weeks before admission he had received an i. m.-injection of nandrolone. Under therapy with neuroleptics the patient recovered completely within 2 months.

    The role of the "heat stroke" is discussed on account of an observation of hyperthermia (42 degrees C or 107.6 Farenheit) that occured with a patient under fluphenazine decanoate, during the summer 1976 heat wave. Contrary to the American descriptions of heat strokes, the patient kept his perspiring ability. Moreover, there was no hypertonic extrapyramidal syndrome, but hypotonia instead. It is to be noted that the preliminary treatment by the corresponding standard neuroleptic (fluphenazine chlorhydrate) did not prevent that hyperthermia whose evolution was rapidly favorable.

    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

    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.

    Nandrolone, an anabolic steroid, slows denervation atrophy of rat muscle, prevents denervation-induced nuclear accumulation of intracellular domain of the Notch receptor, and elevates expression of Numb. Numb acts as an inhibitor of Notch signaling and promotes myogenic differentiation of satellite cells. Turnover of Numb is regulated by mdm2, an E3 ubiquitin ligase. With these considerations in mind, we investigated the effects of nandrolone on the expression of Numb and mdm2 proteins and determined the effect of mdm2 on nandrolone-induced alterations in Numb protein in C2C12 myoblasts. When C2C12 cells were cultured in a medium favoring differentiation (Dulbecco modified Eagle medium containing 2% horse serum), nandrolone up-regulated Numb protein levels in a time-dependent manner and prolonged Numb protein half-life from 10 to 18 hours. In contrast, nandrolone reduced the expression of mdm2 protein. To determine whether the decreased mdm2 expression induced by nandrolone was responsible for the increased levels and prolonged half-life of Numb protein in this cell line, mdm2-small interfering RNA (siRNA) was employed to inhibit mdm2 expression. Compared to cells transfected with scrambled siRNA (negative control), transfection with mdm2-siRNA increased basal Numb protein expression but abolished the further increase in Numb protein levels by nandrolone. In addition, transfection of mdm2-siRNA mimicked the effect of nandrolone to prolong the half-life of Numb protein. Moreover, when C2C12 cells were forced to overexpress mdm2, there was a significant decline in the expression of both basal and inducible Numb protein. Our data suggest that nandrolone, by a novel mechanism for this agent in a muscle cell type, increases Numb protein levels in C2C12 myoblasts by stabilizing Numb protein against degradation, at least in part, via suppression of mdm2 expression.

  3. Differential alterations in gene expression profiles contribute to time-dependent effects of nandrolone to prevent denervation atrophy

    Background Anabolic steroids, such as nandrolone, slow muscle atrophy, but the mechanisms responsible for this effect are largely unknown. Their effects on muscle size and gene expression depend upon time, and the cause of muscle atrophy. Administration of nandrolone for 7 days beginning either concomitantly with sciatic nerve transection (7 days) or 29 days later (35 days) attenuated denervation atrophy at 35 but not 7 days. We reasoned that this model could be used to identify genes that are regulated by nandrolone and slow denervation atrophy, as well as genes that might explain the time-dependence of nandrolone effects on such atrophy. Affymetrix microarrays were used to profile gene expression changes due to nandrolone at 7 and 35 days and to identify major gene expression changes in denervated muscle between 7 and 35 days. Results Nandrolone selectively altered expression of 124 genes at 7 days and 122 genes at 35 days, with only 20 genes being regulated at both time points. Marked differences in biological function of genes regulated by nandrolone at 7 and 35 days were observed. At 35, but not 7 days, nandrolone reduced mRNA and protein levels for FOXO1, the mTOR inhibitor REDD2, and the calcineurin inhibitor RCAN2 and increased those for ApoD. At 35 days, correlations between mRNA levels and the size of denervated muscle were negative for RCAN2, and positive for ApoD. Nandrolone also regulated genes for Wnt signaling molecules. Comparison of gene expression at 7 and 35 days after denervation revealed marked alterations in the expression of 9 transcriptional coregulators, including Ankrd1 and 2, and many transcription factors and kinases. Conclusions Genes regulated in denervated muscle after 7 days administration of nandrolone are almost entirely different at 7 versus 35 days. Alterations in levels of FOXO1, and of genes involved in signaling through calcineurin, mTOR and Wnt may be linked to the favorable action of nandrolone on denervated muscle. Marked

    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.

    Nandrolone is an androgenic-anabolic steroid (AAS) with diverse medical applications but taken indiscriminately by some to rapidly increase muscle mass. The aim of this study was to evaluate the genotoxic and clastogenic potential of nandrolone (deca-durabolin®) in vivo in different cells of mice, using the comet assay and micronucleus test, respectively. The animals received subcutaneous injection of the three doses of the steroid (1.0, 2.5 and 5.0 mg kg⁻¹ body weight). Cytotoxicity was assessed by scoring 200 consecutive total polychromatic (PCE) and normochromatic (NCE) erythrocytes (PCE-NCE ratio). The results showed a significant dose-related increase in the frequency of DNA damage in leukocytes, liver, bone marrow, brain and testicle cells at the three tested doses and a significant increase of the micronucleated polychromatic erythrocytes at all tested doses. Under our experimental conditions, the nandrolone steroid hormone showed genotoxic and clastogenic effects when administered subcutaneously to mice.

    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.

    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.

    The inhibition of growth by octanoic or decanoic acids, two subproducts of ethanolic fermentation, was evaluated in Saccharomyces cerevisiae and Kluyveromyces marxianus in association with ethanol, the main product of fermentation. In both strains, octanoic and decanoic acids, at concentrations up to 16 and 8 mg/liter, respectively, decreased the maximum specific growth rate and the biomass yield at 30°C as an exponential function of the fatty acid concentration and increased the duration of growth latency. These toxic effects increased with a decrease in pH in the range of 5.4 to 3.0, indicating that the undissociated form is the toxic molecule. Decanoic acid was more toxic than octanoic acid. The concentrations of octanoic and decanoic acids were determined during the ethanolic fermentation (30°C) of two laboratory media (mineral and complex) by S. cerevisiae and of Jerusalem artichoke juice by K. marxianus. Based on the concentrations detected (0.7 to 23 mg/liter) and the kinetics of growth inhibition, the presence of octanoic and decanoic acids cannot be ignored in the evaluation of the overall inhibition of ethanolic fermentation.

    Nandrolone (19-nortestosterone) is a widely used anabolic steroid in sports where strength plays an essential role. Once nandrolone has been metabolised, two major metabolites are excreted in urine, 19-norandrosterone (NA) and 19-noretiocholanolone (NE). In 1997, in France, quite a few sportsmen had concentrations of 19-norandrosterone very close to the IOC cut off limit (2ng/ml). At that time, a debate took place about the capability of the human male body to produce by itself these metabolites without any intake of nandrolone or related compounds. The International Football Federation (FIFA) was very concerned with this problematic, especially because the World Cup was about to start in France. In this respect, a statistical study was held with all football players from the first and second divisions of the Swiss Football National League. All players gave a urine sample after effort and around 6% of them showed traces of 19-norandrosterone. These results were compared with amateur football players (control group) and around 6% of them had very small amounts of 19-norandrosterone and/or 19-noretiocholanolone in urine after effort, whereas none of them had detectable traces of one or the other metabolite before effort. The origin of these compounds in urine after a strenuous physical activity is still unknown, but three hypotheses can be put forward. First, an endogenous production of nandrolone metabolites takes place. Second, nandrolone metabolites are released from the fatty tissues after an intake of nandrolone, some related compounds or some contaminated nutritive supplements. Finally, the sportsmen may have taken something during or just before the football game.

  11. Chronic administration of nandrolone increases susceptibility to morphine dependence without correlation with LVV-hemorphin 7 in rats.

    LVV-hemorphin 7 (LVVYPWTQRF; LVV-H7), an N-terminal fragment of the β-chain of hemoglobin cleaved by cathepsin D/pepsin, is an atypical endogenous opioid peptide that is found in high concentration in blood. LVV-H7 acts as a μ-opioid agonist and an inhibitor of insulin-regulated aminopeptidase. Subchronic administration of anabolic androgenic steroids (AAS) has been clinically proven to induce the synthesis of erythrocytes and increase hemoglobin concentrations. Patients with a history of AAS abuse are more susceptible to opioid abuse. We hypothesized that this association could be at least partially attributed to the sensitization of the mesocorticolimbic dopaminergic pathway by LVV-H7. Using the conditioned place preference test and neurochemical analysis, we investigated the possible mechanism underlying the effect of chronic nandrolone administration on morphine-induced reward and its correlation with LVV-H7 in rats. Either LVV-H7 may not sensitize the rewarding neural circuits or its inhibition on locomotor activity could mask reward-related behaviors. Chronic nandrolone pretreatment indeed caused a significant reward by low dose morphine, which did not cause any reward in control rats. However, coadministration of anti-LVV-H7 antiserum with nandrolone did not block this effect. This may rule out the possibility of the involvement of LVV-H7 in the action of nandrolone to intensify morphine-induced reward. Moreover, the serum level of LVV-H7 was mildly increased in response to chronic nandrolone administration in our animal model. According to the current clinical observations, we may conclude that the chronic administration of nandrolone can increase susceptibility to morphine dependence, but that this effect is not related to elevated LVV-H7.

    The Ketogenic diet (KD) is an effective treatment with regards to treating pharmaco-resistant epilepsy. However, there are difficulties around compliance and tolerability. Consequently, there is a need for refined/simpler formulations that could replicate the efficacy of the KD. One of the proposed hypotheses is that the KD increases cellular mitochondrial content which results in elevation of the seizure threshold. Here, we have focussed on the medium-chain triglyceride form of the diet and the observation that plasma octanoic acid (C8) and decanoic acid (C10) levels are elevated in patients on the medium-chain triglyceride KD. Using a neuronal cell line (SH-SY5Y), we demonstrated that 250-μM C10, but not C8, caused, over a 6-day period, a marked increase in the mitochondrial enzyme, citrate synthase along with complex I activity and catalase activity. Increased mitochondrial number was also indicated by electron microscopy. C10 is a reported peroxisome proliferator activator receptor γ agonist, and the use of a peroxisome proliferator activator receptor γ antagonist was shown to prevent the C10-mediated increase in mitochondrial content and catalase. C10 may mimic the mitochondrial proliferation associated with the KD and raises the possibility that formulations based on this fatty acid could replace a more complex diet. We propose that decanoic acid (C10) results in increased mitochondrial number. Our data suggest that this may occur via the activation of the PPARγ receptor and its target genes involved in mitochondrial biogenesis. This finding could be of significant benefit to epilepsy patients who are currently on a strict ketogenic diet. Evidence that C10 on its own can modulate mitochondrial number raises the possibility that a simplified and less stringent C10-based diet could be developed.

    Affective disorders and impulsivity are quite common when using anabolic substances, in this case-study one of the rather rare cases of a psychotic disorder following the abuse of androgenic steroids is described. A 30-year old formerly healthy white male was admitted as inpatient to psychiatric hospital showing symptoms of anxiety and paranoid ideation. In the last 1.5 years he had consumed androgenic steroids, directly before the onset of the first psychotic symptoms 8 weeks before admission he had received an i.m.-injection of nandrolone. Under therapy with neuroleptics the patient recovered completely within 2 months.

    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 17α-methyltestosterone (17α-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 7.5mg/kg, but not at 0.075 mg/kg, the lower dose tested. Conversely, mice receiving 17α-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 17α-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. PMID:19028026

    In this study, an optically accessible heavy-duty diesel engine was used to investigate the impact of methyl decanoate (MD) on combustion and emissions. A specific goal of the study was to determine if MD could enable soot-free leaner-lifted flame combustion (LLFC) – a mode of mixing-controlled combustion associated with fuel-air equivalence ratios below approximately two. An ultra-low sulfur diesel certification fuel (CF) was used as the baseline fuel, and experiments were conducted at two fuel-injection pressures with three levels of charge-gas dilution. In addition to conventional pressure-based and engine-out emissions measurements, exhaust laser-induced incandescence, in-cylinder natural luminosity (NL), and in-cylinder chemiluminescence (CL) diagnostics were used to provide detailed insight into combustion processes.

    The experimental study of the thermal decomposition of methyl decanoate was performed in a jet-stirred reactor at temperatures ranging from 773 to 1123 K, at residence times between 1 and 4 s, at a pressure of 800 Torr (106.6 kPa) and at high dilution in helium (fuel inlet mole fraction of 0.0218). Species leaving the reactor were analyzed by gas chromatography. Main reaction products were hydrogen, carbon oxides, small hydrocarbons from C1 to C3, large 1-olefins from 1-butene to 1-nonene, and unsaturated esters with one double bond at the end of the alkyl chain from methyl-2-propenoate to methyl-8-nonenoate. At the highest temperatures, the formation of polyunsaturated species was observed: 1,3-butadiene, 1,3-cyclopentadiene, benzene, toluene, indene, and naphthalene. These results were compared with previous ones about the pyrolysis of n-dodecane, an n-alkane of similar size. The reactivity of both molecules was found to be very close. The alkane produces more olefins while the ester yields unsaturated oxygenated compounds. A detailed kinetic model for the thermal decomposition of methyl decanoate has been generated using the version of software EXGAS which was updated to take into account the specific chemistry involved in the oxidation of methyl esters. This model contains 324 species and 3231 reactions. It provided a very good prediction of the experimental data obtained in jet-stirred reactor. The formation of the major products was analyzed. The kinetic analysis showed that the retro-ene reactions of intermediate unsaturated methyl esters are of importance in low reactivity systems. PMID:23710078

    Pennsylvania (PA) State Racing Commissions regulate the endogenous androgenic steroid, testosterone (TES), in racing intact males (RIM) by quantification of TES in post-race samples. Post-race plasma samples (2209) collected between March 2008 and November 2010 were analyzed for TES, nandrolone (NAN), and other anabolic steroids (ABS). Of the 2209 plasma samples, 2098 had quantifiable TES ≥ 25 pg/mL. Plasma (mean ± SD) concentrations of TES and NAN in RIM were 329.2 ± 266.4 and 96.0 ± 67.8 pg/mL, respectively. Only 64.6% of RIM had quantifiable concentration of NAN, and there was no relationship between TES and NAN. Plasma TES concentrations were significantly (P < 0.0001) higher during the months of April, May, June, July, and August. A significantly higher (P < 0.006) plasma TES was observed in Thoroughbred (TB) (347.6 ± 288.5 pg/mL) vs. that in Standardbred (STB) (315.4 ± 247.7 pg/mL). Plasma concentrations of TES from breeding stallions (BS) were 601.6 ± 356.5 pg/mL. Statistically significant (P < 0.0001) lower plasma concentrations of the two steroids were observed in RIM horses. Based on quantile distribution of TES in the RIM and BS populations, 99.5% were at or below 1546.1 and 1778.0 pg/mL, respectively. Based on this population of RIM, the suggested upper threshold plasma concentration of endogenous TES in horses competing in PA should remain at 2000 pg/mL.

    The impact of exogenic testosterone (T): 1.5 and 3.0 mg/kg.bw) and 19-nortestosterone 17-decanoate (ND): 1.5 and 7.5 mg/kg.bw) in castrated male rats was evaluated based on: (a) weight increase of the androgen target tissues, respecting the Hershberger methodology; (b) the 17α and β-testosterone, 17 α and β-estradiol and 17 α and β-nortestosterone levels using the GC-MS/MS technique; and (c) observation of the serum free thyroxine levels (T4). 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

    Films made of cis-bis-decanoate-tin(IV) phthalocyanine (PcSn10) and racemic dipalmitoylphosphatidylcholine (DPPC) are studied with compression isotherms and Brewster angle microscopy (BAM) at the air/water interface. Films enriched in PcSn10 present phase separation elliptical-shaped domains. These domains present optical anisotropy and molecular order. They are enriched in PcSn10, and the film outside these domains is enriched in DPPC, as shown in by high-angle annular dark-field transmission electron microscopy on Langmuir-Blodgett (LB) transferred films. Film collapse area and atomic force microscopy images of LB transferred films on mica indicate that the films are actually multilayers. A computational survey was performed to determine how the PcSn10 molecules prefer to self-assemble, in films basically made of PcSn10. The relative energetic stability for several dimeric assemblies was obtained, and a crystal model of the film was developed through packing and repeating the PcSn10 molecules, along the crystallographic directions of the unit cell. Our results contribute to understanding the strong interaction between PcSn10 and DPPC at the air/water interface, where even small quantities of DPPC (~1-2%) can modify the film in an important way.

    Zuclopenthixol serum concentrations were measured in 58 psychiatric patients referred for routine therapeutic drug monitoring (TDM). Patients were treated for prolonged time with zuclopenthixol decanoate in viscoleo in doses of 50-500 mg, administered intramuscularly at 14-day intervals. The serum concentration was determined at days 7 (C7) and 14 (C14) following injection. The mean ratio C7/C14 was 2.0 and was independent of the dosage given. In 14 patients, additional blood samples were drawn at day 3 (C3) following injection. The mean ratio C3/C14 of this group was 3.2. An almost log-linear decline of the serum concentration from day 3 to 14 appeared, which corresponds to an apparent half-life of zuclopenthixol in this dosage form of 7.4 days. The marked fluctuations of serum concentrations of zuclopenthixol from peak to trough levels in patients given fortnightly injections of the depot preparation indicate that shorter intervals between injections should be considered in many cases in order to diminish side effects.

    Several substances such as anabolic androgenic steroids (AAS), peptide hormones like insulin-like growth factor-I (IGF-I), aromatase inhibitors and estrogen antagonists are offered via the Internet, and are assumed without considering the potential deleterious effects that can be caused by their administration. In this study we aimed to determine if nandrolone and stanozolol, two commonly used AAS, could have an effect on Leydig cell tumor proliferation and if their effects could be potentiated by the concomitant use of IGF-I. Using a rat Leydig tumor cell line, R2C cells, as experimental model we found that nandrolone and stanozolol caused a dose-dependent induction of aromatase expression and estradiol (E2) production. When used in combination with IGF-I they were more effective than single molecules in inducing aromatase expression. AAS exhibited estrogenic activity and induced rapid estrogen receptor (ER)-dependent pathways involving IGF1R, AKT, and ERK1/2 phosphorylation. Inhibitors for these kinases decreased AAS-dependent aromatase expression. Up-regulated aromatase levels and related E2 production increased cell proliferation as a consequence of increased cyclin E expression. The observation that ER antagonist ICI182,780 was also able to significantly reduce ASS- and AAS + IGF-induced cell proliferation, confirmed a role for estrogens in AAS-dependent proliferative effects. Taken together these data clearly indicate that the use of high doses of AAS, as it occurs in doping practice, enhances Leydig cell proliferation, increasing the risk of tumor development. This risk is higher when AAS are used in association with IGF-I. To our knowledge this is the first report directly associating AAS and testicular cancer.

    Daptomycin, a cyclic anionic lipopeptide compound produced by Streptomyces roseosporus, is used to treat skin infections caused by multi-drug resistant gram-positive pathogens. The biosynthesis of daptomycin is initiated by the condensation of decanoic acid (DA, a 10-carbon unit fatty acid) and the N-terminal l-tryptophan. So, the addition of DA to the fermentation medium is essential for increasing daptomycin production. However, increasing of DA concentration in the fermentation medium was not possible due to the high toxicity of DA. The previous studies reported that the cell growth of S. roseosporus was halted from 1 mM DA. In order to improve daptomycin production with increasing DA concentration in the medium, the DA-resistant S. roseosporus was developed via a sequential-adaptation method. The DA-resistant strain (DAR) showed complete resistance to 1 mM DA, and the daptomycin production was increased 1.4-fold (40.5 ± 0.7 mg/L) compared with the wild-type (28.5 ± 0.8 mg/L) at 1 mM DA. Additionally, the initial step of the daptomycin biosynthesis was enhanced by the overexpression of dptE and dptF in DAR. The dptEF overexpression DAR showed 3.9-fold (156.3 ± 8.2 mg/L) increase in the daptomycin production compared with DAR (40.1 ± 2.6 mg/L) at 1 mM DA.

    Several doping agents, such as anabolic androgenic steroids (AAS) and peptide hormones like insulin-like growth factor-I (IGF-I), are employed without considering the potential deleterious effects that they can cause. In addition, androgens are used in postmenopausal women as replacement therapy. However, there are no clear guidelines regarding the optimal therapeutic doses of androgens or long-term safety data. In this study we aimed to determine if two commonly used AAS, nandrolone and stanozolol, alone or in combination with IGF-I, could activate signaling involved in breast cancer cell proliferation. Using a human breast cancer cell line, MCF-7, as an experimental model we found that both nandrolone and stanozolol caused a dose-dependent induction of aromatase expression and, consequently, estradiol production. Moreover, when nandrolone and stanozolol were combined with IGF-I, higher induction in aromatase expression was observed. This increase involved phosphatidylinositol 3-kinase (PI3K)/AKT and phospholipase C (PLC)/protein kinase C (PKC), which are part of IGF-I transductional pathways. Specifically, both AAS were able to activate membrane rapid signaling involving IGF-I receptor, extracellular regulated protein kinases 1/2 (ERK1/2) and AKT, after binding to estrogen receptor (ER), as confirmed by the ability of the ER antagonist ICI182, 780 to block such activation. The estrogenic activity of nandrolone and stanozolol was further confirmed by their capacity to induce the expression of the ER-regulated gene, CCND1 encoding for the cell cycle regulator cyclin D1, which represents a key protein for the control of breast cancer cell proliferation. In fact, when nandrolone and stanozolol were combined with IGF-I, they increased cell proliferation to levels higher than those elicited by the single factors. Taken together these data clearly indicate that the use of high doses of AAS, as occurs in doping practice, may increase the risk of breast cancer. This

    Determination of whether the major metabolite of nandrolone in urine, 19-norandrosterone (19-NA), is exogenous or endogenous in origin is one of the most exciting challenges for antidoping laboratories. Gas chromatography-combustion-isotope ratio mass spectrometry (GC-C-IRMS) can be used to differentiate these two origins by carbon isotopic ratio analysis. A complete method for purification of 19-NA in urine has been established. Acetylated ketosteroids, and in particular 19-NA, are isolated from the urine matrix before analysis after hydrolysis and purification of urine by reversed-phase and normal solid-phase extraction. The limit of detection for 19-NA was about 60 ng with recoveries of 54-60%. Evidence of exogenous administration of 19-NA may be established from isotope ratio determination from the 13C/12C ratios of several synthetic 19-norsteroids compared to those obtained for endogenous steroids.

    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.

    The capacity of several strains of yeasts to do the bioconversion of methyl ricinoleate into gamma-decalactone, was studied in a medium containing this methylic ester of fatty acid as sole carbon source. Amongst the strains which are able to do this bioconversion, two types of behaviour are observed: some of the strains produce gamma-decalactone during all the incubation in bioconversion medium while others produce this aroma compound very quickly and then consume it fast too. The tested strains produce at the same time gamma-decalactone and the corresponding acid form (4-hydroxy-decanoic acid), and this, in variable proportions.

    Fish oils contain essential polyunsaturated fatty acids of the n-3 family. In fat malabsorption the n-3 fatty acids are poorly absorbed. Absorption may be improved by modifying the fatty acid profile of fish oil through interesterification with medium chain fatty acids. We examined the absorption of fish oil interesterified with decanoic acid in rats with normal- and malabsorption compared to a physical mixture and the fish oil itself. The interesterified fats were: 1) a regiospecific fat with decanoic acid located mainly in the sn1/3-positions and a long chain fatty acid from fish oil in the sn2-position, 2) a fat with a random distribution of fatty acids in all positions of the triacylglycerol. The main mesenteric lymph duct was cannulated for collection of lymph. In the malabsorbing rats the common bile duct was cannulated as well to divert both pancreatic juice and bile. The fatty acid composition in lymph samples collected for 24 hours was determined. Accumulated transport of n-3 fatty acids from fish oil was improved in malabsorbing rats and recoveries of fatty acids after 24 hours were improved in both rats with normal- and malabsorption administered the randomized fat compared to fish oil.

    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.

    Objectives: In the UK, nine different compounds are available as long-acting antipsychotic injections (LAIs). There are few clinical guidelines for determining which LAIs are most effective in specific patient groups. To measure the clinical effectiveness of LAIs we aimed to determine the now-established concept of antipsychotic discontinuation rates and measure Clinical Global Impression (CGI) outcomes. Method: The population (n was approximately 560,000) was a secondary care NHS adult mental health service in Lanarkshire, Scotland, UK. This was a retrospective, electronic case note search of LAI-naïve patients commenced on paliperidone palmitate (n = 31), risperidone long-acting injection (RLAI) (n = 102) or zuclopenthixol decanoate (n = 105), with an 18-month follow up. Kaplan–Meier survival statistics for discontinuation rates and hospital admission were calculated. CGI severity and improvement scores were retrospectively assigned by the investigating team. Results: Paliperidone palmitate performed less favourably than risperidone long-acting injection (RLAI) or zuclopenthixol decanoate. Paliperidone palmitate had higher discontinuation rates due to any cause, inefficacy and increased hospitalization risk. Paliperidone palmitate had the smallest proportion of patients assigned a clinically desirable CGI-I score of 1 (very much improved) or 2 (much improved). Conclusions: Paliperidone palmitate had less favourable discontinuation and CGI outcomes compared with RLAI and zuclopenthixol decanoate. This could not be adequately explained by patients in the paliperidone group being more chronically or severely unwell, nor by the presence of comorbidities such as alcohol or substance misuse, or by the use of lower mean dosages compared with RLAI or zuclopenthixol decanoate. We considered that prescribers are familiarizing themselves with paliperidone and outcomes may improve over time. PMID:26913175

    The detection of steroid residues in hair is a powerful strategy to demonstrate long-term administration of these growth promoters in meat production animals. Analysis of the ester form of administered steroids is an unambiguous approach to prove the illegal use of natural hormones. For detection, gas chromatography-mass spectrometry (GC-MS/MS) was generally used. However, recent advances in liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology have improved the robustness and potential sensitivity of this method. This paper describes development and validation, according to Commission Decision 2002/657/EC, of LC-MS/MS and GC-MS/MS methods, in two separate laboratories, for determination of steroid esters in bovine hair. Bovine hair samples taken from animals treated with estradiol-3-benzoate and nortestosterone decanoate, as well as from an untreated animal, were used to evaluate the comparability of the results of the two validated methods. The results of the inter-comparison demonstrate that both the LC-MS/MS and the GC-MS/MS methods are fit for purpose and capable of determining steroid esters in hair samples from treated bovine animals.

    17β-Nandrolone (17β-NT) is one of the most frequently misused anabolic steroids in meat producing animals. As a result of its extensive metabolism combined with the possibility of interferences with other endogenous compounds, detection of its illegal use often turns out to be a difficult issue. In recent years, proving the illegal administration of 17β-NT became even more challenging since the presence of endogenous presence of 17β-NT or some of its metabolite in different species was demonstrated. In bovines, 17α-NT can occur naturally in the urine of pregnant cows and recent findings reported that both forms can be detected in injured animals. Because efficient control must both take into account metabolic patterns and associated kinetics of elimination, the purpose of the present study was to investigate further some estranediols (5α-estrane-3β,17β-diol (abb), 5β-estrane-3α,17β-diol (bab), 5α-estrane-3β,17α-diol (aba), 5α-estrane-3α,17β-diol (aab) and 5β-estrane-3α,17α-diol (baa)) as particular metabolites of 17β-NT on a large number of injured (n=65) or pregnant (n=40) bovines. Whereas the metabolites abb, bab, aba and baa have previously been detected in urine up to several days after 17β-NT administration, the present study showed that some of the isomers abb (5α-estrane-3β,17β-diol) and bab (5β-estrane-3α,17β-diol) could not be detected in injured or pregnant animals, even at very low levels. This result may open a new way for the screening of anabolic steroid administration considering these 2 estranediols as biomarkers to indicate nandrolone abuse in cattle.

    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.

    To investigate the effects of concurrent administration of an anabolic steroid upon hematopoiesis and metabolism in patients with cancer who were receiving cytotoxic chemotherapy, a randomized trial was conducted. Thirty-three evaluable patients received intensive multiple-agent chemotherapy: 17 received in addition nandrolone decanoate ("Deca-Durabolin"), 200 mg intramuscularly each week. The nandrolone-treated patients showed significantly better maintenance of hemoglobin concentrations and body weight, and a highly significant reduction in number of blood transfusions. Improved survival in the androgen-treated patients did not achieve significance. There were no differences in neutrophil or platelet counts or in tolerance of cytotoxic drugs. Toxicity from nandrolone therapy was minimal.

    1996-09-01

    A randomized study of nandrolone decanoate (Deca-Durabolin) showed that the anabolic steroid can increase weight in people with HIV infections. The group receiving nandrolone experienced a greater increase both in fat-free mass and body cell mass (although the latter measure did not reach statistical significance) than those on placebo. Deca-Durabolin had little to do with two occurrences of Kaposi's sarcoma (KS) in the study group, but until further studies are completed, caution is advised when using this steroid in patients with KS. A new study comparing nandrolone to growth hormone in patients with wasting is slated to begin in the next 3 or 4 months.

    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.

    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.

    Oil depots are parenteral drug formulations meant for sustained release of lipophilic compounds. Until now, a comprehensive understanding of the mechanism of drug absorption from oil depots is lacking. The aim of this paper was to fill this gap. A clinical study with healthy volunteers was conducted. An oil depot with nandrolone decanoate and benzyl alcohol was subcutaneously administered in the upper arm of female volunteers. Pharmacokinetic profiles of both substances were related to each other and to literature data. Benzyl alcohol absorbs much more rapidly than nandrolone. In detail, it appears that benzyl alcohol enters the central compartment directly, while nandrolone decanoate is recovered in serum after a lag time. This lag time is also seen in literature data, although not reported explicitly. The absorption of nandrolone is enhanced by the presence of benzyl alcohol. This is most likely an effect of altered oil viscosity and partition coefficient between the oil and aqueous phase. The absorption rate constant of compounds is found to be related to the logP of the solubilized prodrug. The absorption rate is however not only determined by the physico-chemical properties of the formulation but also by the tissue properties. Here, it is argued that lymphatic flow must be considered as a relevant parameter.

    Dried blood spot (DBS) sampling, a technique for whole blood sampling on a piece of filter paper, has more than 50-years tradition, particularly in the diagnostic analysis of metabolic disorders in neonatal screening. Due to the minimal invasiveness, straightforwardness, robustness against manipulation and fastness DBS sampling recommends itself as an advantageous technique in doping control analysis. The present approach highlights the development of a screening assay for the analysis of eight anabolic steroid esters (nandrolone phenylpropionate, trenbolone enanthate, testosterone acetate, testosterone cypionate, testosterone isocaproate, testosterone phenylpropionate, testosterone decanoate and testosterone undecanoate) and nandrolone in DBS. The detection of the intact esters allows an unequivocal proof of the administration of conjugates of exogenous testosterone and its derivatives. Precise, specific and linear conditions were obtained by means of liquid chromatography high resolution/high accuracy mass spectrometry. Sensitivity in the low ppb range was accomplished by the preparation of the methyloxime derivatives of the target compounds. Labeled internal standards (d3-nandrolone, d3-nandrolone caproate and d3-nandrolone undecanoate) were applied to compensate for the broad range in chain length of the esters. The assay presented here outlines the application of DBS for the analysis of anabolic steroid esters in doping controls for the first time providing great potential to simplify the proof of exogenous administration of testosterone.

    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.

  10. Dihydrotestosterone and estrogen regulation of rat brain androgen-receptor immunoreactivity.

    PubMed

    Lynch, C S; Story, A J

    Androgen-receptor upregulation that occurs with androgenic-anabolic steroid (AAS) administration may be mediated by AAS metabolites, dihydrotestosterone (DHT), and estrogen. Castrated and intact male rats received 14 s.c. daily injections of AAS (2 mg/kg testosterone cypionate, 2 mg/kg nandrolone decanoate, and 1 mg/kg boldenone undecylenate in sesame oil vehicle), DHT (5 mg/kg dihydrotestosterone), EB (5 mg/kg estradiol benzoate), or sesame oil vehicle. Approximately 18-24 h after the fourteenth injection, brain tissues were removed and processed immunocytochemically using the PG-21 androgen-receptor antibody. As reported before, castration eliminated AR-ir (androgen-receptor immunoreactivity) and AAS upregulated AR-ir in the ventromedial hypothalamus (VMHVL), medial amygdala (MePV), and medial preoptic area (MPOM). When compared to AAS, DHT fully upregulated AR-ir in the VM VL and MPOM and partially upregulated AR-ir in the MePV. EB treatment partially upregulated AR-ir in the VMHVL and MePV, but not in the MPOM of castrated rats. Because AR-ir in the MPOM was consistently upregulated by DHT or AAS, and not EB, androgen-receptor availability in this region may be mediated specifically via androgen receptors.

    Cellular responses in the compensatory hypertrophied (plantaris) muscle induced by surgical ablation of synergistic muscles (soleus and gastrocnemius) were determined during 10-week anabolic androgenic steroid (AAS) treatment. Adult Wistar male rats were divided randomly into the Control and Steroid groups, and contralateral surgery was performed. Nandrolone decanoate was administered to the Steroid group. [3H]thymidine and [14C]leucine labeling were used to determine the serial changes in cellular mitotic activity and amino acid uptake. Myogenic cells and cellular responses in blood vessels and nerve fibers were analyzed by immunohistochemistry. Significantly lower cellular mitotic activity associated with lower volume of muscle fiber necrosis was observed in the Steroid group during the first week. However, amino acid uptake and final muscle wet weight gain did not differ between the groups. Marked activation/proliferation of muscular, vascular, and peripheral nerve-related cells was seen with the inflammatory responses in both groups. However, this activation was dependent on the volume of muscle fiber damage and was not preferentially accelerated by AAS loading. These results indicated that AAS loading significantly diminished muscle fiber damages, but they did not accelerate final muscle wet weight gain and activation of myogenic, vascular, and peripheral nerve related cells in the compensatory enlarged muscles.

    Muscle wasting has long been recognized as a major clinical problem in hemodialysis (HD) patients. In addition to its impact on quality of life, muscle wasting has been proven to be associated with increased mortality rates. Identification of the molecular mechanisms underlying muscle wasting in HD patients provides opportunities to resolve this clinical problem. Several signaling pathways and humeral factors have been reported to be involved in the pathogenic mechanisms of muscle wasting in HD patients, including ubiquitin-proteasome system, caspase-3, insulin/insulin-like growth factor-1 (IGF-1) signaling, endogenous glucocorticoids, metabolic acidosis, inflammation, and sex hormones. Targeting the aforementioned crucial signaling and molecules to suppress protein degradation and augment muscle strength has been extensively investigated in HD patients. In addition to exercise training, administration of megestrol acetate has been proven to be effective in improving anorexia and muscle wasting in HD patients. Correction of metabolic acidosis through sodium bicarbonate supplements can decrease muscle protein degradation and hormone therapy with nandrolone decanoate has been reported to increase muscle mass. Although thiazolidinedione has been shown to improve insulin sensitivity, its role in the treatment of muscle wasting remains unclear. This review paper focuses on the molecular pathways and potential new therapeutic approaches to muscle wasting in HD patients. PMID:24382946

    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.

    The efficacy of anabolic steroid treatment [0.3 or 0.9 mg nandrolone decanoate (Deca-Durabolin) per day] was examined in the context of sparing rodent fast-twitch plantaris and slow-twitch soleus muscle weight, sparing subcellular protein, and altering isomyosin expression in response to hindlimb suspension. Female rats were assigned to four groups (7 rats/group for 6 wk): 1) normal control (NC), 2) normal steroid (NS), 3) normal suspension (N-SUS), and 4) suspension steroid (SUS-S). Compared with control values for the plantaris and soleus muscles, suspension induced 1) smaller body and muscle weight (P less than 0.05), 2) losses in myofibril content (mg/muscle, P less than 0.05), and 3) shifts in the relative expression (expressed as %of total isomyosin) of isomyosins which favored lesser slow myosin and greater fast myosin isotypes (P less than 0.05). Steroid treatment of suspended animals (SUS-S vs. N-SUS) partially spared body and muscle weight (P less than 0.05) and spared plantaris but not soleus myofibril content (mg/muscle, P less than 0.05). However, steroid treatment did not modify the isomyosin pattern induced by suspension. In normal rats (NS vs. NC), steroid treatment enhanced body and plantaris muscle weight but not soleus weight (P less than 0.05) and did not alter isomyosin expression in either muscle type. Collectively these data suggest that in young female rats anabolic steroids 1) enhance the body weight and the weight of a fast-twitch ankle extensor in normal rats, 2) ameliorate the loss in body weight, fast-twitch muscle weight and protein content and slow-twitch muscle weight associated with hindlimb suspension.(ABSTRACT TRUNCATED AT 250 WORDS)

    Anabolic-androgenic steroids (AAS) are synthetic androgen-like compounds which are taken in high doses by athletes with the intention of enhancing muscular appearance, strength and/or athletic performance. Recent research indicates that high doses of AAS may influence the functions of the hippocampus. This evidence led us to explore the extent to which chronic AAS treatments influence spatial memory and the integrity of the hippocampus in the rat. Gonadally intact adult male Long-Evans rats were treated with either the AAS methandrostenolone, a steroid 'cocktail' (TNB; testosterone cypionate, boldenone undecylenate and nandrolone decanoate), or the oil vehicle daily for 12 weeks. A group of male rats treated with corticosterone (CORT; 10 mg/day) was also examined. Spatial memory was assessed in the Morris water maze after 10 weeks of hormone treatment. At 12 weeks, the animals were sacrificed, blood collected and the brain sectioned to assess hippocampal cell number. There were no impairments in the acquisition or retention of the Morris water maze in any hormone treatment group. Although serum testosterone levels were elevated in rats treated with TNB relative to the oil controls, neither the TNB or methandrostenolone treatments produced changes in hippocampal cell number. Serum CORT levels were significantly elevated in the rats treated with CORT and cell loss (15%) was detectable in the CA3b subfield in this group of animals. These results indicate that the AAS administered in the present study were not detrimental to hippocampal spatial memory or cell survival and that, while chronic CORT may produce mild hippocampal cell loss, this loss is not accompanied by deficits on a spatial memory task.

    Summary 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 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.

    Doping control of anabolic substances is normally carried out with urine samples taken from athletes and horses. Investigation of alternative specimens, e.g. hair samples, is restricted to special cases, but can also be worthwhile, in addition to urine analysis. Moreover, hair material is preferred in cases of limited availability or complicated collection of urine samples, e.g. from horses. In this work, possible ways of interpretation of analytical results in hair samples are discussed and illustrated by practical experiences. The results demonstrate the applicability of hair analysis to detect anabolic steroids and also to obtain further information about previous abuse. Moreover, the process of incorporation of steroids into hairs is described and the consequences on interpretation are discussed, e.g. on the retrospective estimation of the application date. The chosen examples deal with the detection of the anabolic agent testosterone propionate. Hair samples of an application study, as well as a control sample taken from a racing horse, were referred to. Hair material was investigated by a screening procedure including testosterone, nandrolone and several esters (testosterone propionate, phenylpropionate, decanoate, undecanoate, cypionate; nandrolone decanoate, dodecanoate and phenylpropionate; limits of detection (LODs) between 0.1 and 5.0 pg/mg). Confirmation of testosterone propionate (LOD 0.1 pg/mg) was carried out by an optimised sample preparation. Trimethylsilyl (TMS) and tert-butyl dimethylsilyl derivatives were detected by gas chromatography-high-resolution mass spectrometry (GC-HRMS) and gas chromatography-tandem mass spectrometry (GC-MS/MS).

    The purpose of this study was to ascertain whether anabolic steroids act synergistically with functional overload in terms of increasing muscle weight and subcellular protein content of normal overloaded and suspended overloaded rodent plantaris muscle. Female rats were randomly assigned to six groups (7 rats/group) for 6 wk: 1) normal control (NC), 2) overload (OV), 3) overload steroid (OV-S), 4) normal suspended (N-SUS), 5) overload suspended (OV-SUS), and 6) overload suspended steroid (OV-SUS-S). Rats receiving anabolic steroid were administered 0.3 mg nandrolone decanoate (Deca-Durabolin) per day. Relative to control values, overload induced 1) sparing of muscle weight of the OV-SUS group as well as larger absolute and normalized (mg muscle/g body wt) muscle weight of the OV group (P less than 0.05), 2) greater protein content (mg/muscle, P less than 0.05), and 3) an increased relative expression of slow myosin in both the OV and OV-SUS groups (P less than 0.05). Although anabolic steroid treatment of overload animals (OV-S) did not alter further the pattern of response of any parameter analyzed for the OV group, it did induce larger absolute and normalized muscle weight (P less than 0.05) as well as a greater protein content (mg/muscle, P less than 0.05) of the OV-SUS-S group compared with control values. However, anabolic steroid treatment did not alter the pattern of isomyosin expression observed in the overload (OV-S vs. OV) or overload suspended (OV-SUS-S vs. OV-SUS) groups.(ABSTRACT TRUNCATED AT 250 WORDS)

    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.

    We developed and validated a method to detect and quantify 12 anabolic steroids in blood (androstenedione, dihydrotestosterone, boldenone, epitestosterone, mesterolone, methandienone, nandrolone, stanozolol, norandrostenedione, tamoxifene, testosterone, trenbolone) and eight more in hair samples (nandrolone phenylpropionate, nandrolone decanoate, testosterone propionate, testosterone benzoate, testosterone cypionate, testosterone decanoate, testosterone phenylpropionate, testosterone undecanoate) using liquid chromatography coupled to high-resolution mass spectrometry. This method used a benchtop Orbitrap mass spectrometer operating with an APCI probe under positive ionization mode. Analysis was realized in full scan experiment with a nominal resolving power of 140,000. After addition of the internal standard (testosterone-D3) and incubation in phosphate buffer pH = 5 for hair, 200 μL of blood and 30 mg of hair samples were extracted with heptane. LOQ and LOD were determined at 5 and 1 ng mL(-1) in whole blood and 10 to 100 pg mg(-1) and 2 to 20 pg mg(-1) in hair according to the compounds, respectively. The method was linear in the 5-1000 ng mL(-1) range in whole blood and between 10 or 100 pg mg(-1) and 1000 pg mg(-1) in hair with correlation coefficients >0.99, and intra- and inter-day accuracy and precision were <14.8% for all compounds except for some esters in hairs (<19.9%) probably due to an important matrix effect for these compounds. This sensitive and specific method to detect anabolic steroids has been successfully applied to two real cases, for which various anabolic steroids in whole blood, urine, and hair were identified and quantified.

    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.

    1. Tardive dyskinesia (TD) is a serious side-effect of long-term treatment with neuroleptics. To investigate if neuroleptic-induced excessive stimulation of striatal glutamate receptors may underlie TD development, the effect of the NMDA antagonist, memantine (1-amino-3,5-dimethyladamantane), was studied in a rat model of TD. 2. In an acute experiment, six groups of rats were treated daily for 1 week with either vehicle or memantine 20 or 40 mg kg-1 day-1, and on the seventh day they received one injection of either haloperidol 1.0 mg kg-1 i.p. or saline i.p. In a subsequent long-term experiment lasting 20 weeks, the same treatment was continued, except that haloperidol was injected i.m. as decanoate (38 mg kg-1 every 4 weeks) and control rats received sesame oil. The behaviour was videotaped and scored at intervals during both experiments, and for 16 weeks after cessation of the long-term treatment. 3. In the acute experiment, haloperidol decreased motor activity and memantine increased moving and tended to attenuate the immobility induced by haloperidol. Memantine also enhanced the haloperidol-induced increase in the putative TD-analogue vacuous chewing movements (VCM). 4. In the long-term experiment, the most marked effect of haloperidol was a gradual increase in VCM and the increase persisted significantly for 12 weeks after cessation of treatment. Memantine dose-dependently increased VCM and moving during long-term treatment. However, only one week after stopping treatment, both these effects of memantine disappeared. In contrast to rats previously treated with haloperidol alone, rats co-treated with memantine (both doses) and haloperidol had VCM at the level of controls two weeks after stopping treatment. The blood levels of drugs were within the therapeutic range achieved in human subjects. 5. These results suggest that long-lasting changes induced by haloperidol are prevented by memantine, which supports the theory that excessive NMDA receptor stimulation

  9. Investigations into the feasibility of routine ultra high performance liquid chromatography-tandem mass spectrometry analysis of equine hair samples for detecting the misuse of anabolic steroids, anabolic steroid esters and related compounds.

    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

    The abuse of synthetic esters of natural steroids such as testosterone and estradiol in cattle fattening and sports is hard to detect via routine urine testing. The esters are rapidly hydrolysed in vivo into substances which are also endogenously present in urine. An interesting alternative can be provided by the analysis of the administered synthetic steroids themselves, i.e., the analysis of intact steroid esters in hair by liquid chromatography tandem mass spectrometry (LC/MS/MS). However, retrospective estimation of the application date following a non-compliant finding is hindered by the complexity of the kinetics of the incorporation of steroid esters in hair. In this study, the incorporation of intact steroid esters in hair following pour-on treatment has been studied and critically compared with results from intramuscular treatment. To this end animals were pour-on treated with a hormone cocktail containing testosterone cypionate, testosterone decanoate and estradiol benzoate in different carriers. The animals were either treated using injection and pour-on application once or three times having 1 week between treatments using injection and pour-on application. Animals were slaughtered from 10-12 weeks after the last treatment. Both hair and blood plasma samples were collected and analysed by LC/MS/MS. From the results, it is concluded that after single treatment the levels of steroid esters in hair drop to CCbeta levels (5-20 microg/kg) after 5-7 weeks. When treatment is repeated two times, the CCbeta levels are reached after 9-11 weeks. Furthermore, in plasma, no steroid esters were detected; not even at the low microgramme per litre level but--in contrast with the pour-on application--after i.m. injection, significant increase of 17beta-testosterone and 17beta-estradiol were observed. These observations suggest that transport of steroid esters after pour-on application is not only performed by blood but also by alternative fluids in the animal so

    A precondition for the successful treatment of headaches is the correct headache diagnosis. Triptans are effective for attack treatment of migraine and cluster headache. However, there are not effective for the treatment of tension-type headache. For the prevention of frequent episodic migraine betablockers, flunarizine, topiramate and amitriptyline are recommended. For the prevention of chronic migraine evidence is only available for onabotulinumtoxinA and topiramate. For prophylactic treatment of tension-type headaches tricyclic antidepressants are used. In cluster headache verapamil (in combination with steroids) is the most frequently used prophylactic agent. This article focusses on the current acute and prophylactic treatment of common headache syndromes.

    In order to assess the relationship between anabolic steroid administration and gynecomastia, we studied the effects produced by administering nandrolone decanoate and a mixture of propionate, phenilpropionate, isocaproate and testosterone decanoate to bodybuilders during a six month period. The following significant changes occurred: a 53% reduction in serum testosterone; LH and FSH levels were suppressed to 77% and 87%, respectively, in comparison to control values; and although 45% of the subjects showed an increase in serum estradiol levels, no statistically significant differences were found compared with control estradiol levels. With regard to estradiol and androgen receptors, 85% of gynecomastia tissue contained estradiol or androgen receptors, while 40% contained both. The mean values of estradiol and androgen receptors in the cytosol were 65 +/- 10 and 52 +/- 5 fmol/mg protein, respectively. Nuclear androgen and estradiol receptor levels were 33 +/- 7 and 67.5 +/- 9 fmol/mg protein, respectively. The presence of hormone receptors in gynecomastia receptive cells provides support for the hypothesis that gynecomastia is steroid-dependent.

  16. A novel pharmacological approach of musculoskeletal losses associated with simulated microgravity.

    PubMed

    Exposure to microgravity (weightlessness) is known to cause rapid bone and muscle losses. We have used the hind limb-suspended (HLS) rat model to simulate microgravity-induced musculoskeletal losses in order to assess resulting hormonal changes and to develop a novel pharmacological countermeasure. Previously, we demonstrated significant decreases in circulatory hormonal levels [serum thyroxin, 1,25(OH)2 vitamin D (p<0.05), and serum testosterone (p<0.001)] in HLS rats. Both thyroxin and 1,25(OH)2 vitamin D levels returned to normal soon after removal from HLS, while testosterone levels matched normal levels only after a further 3-4 weeks. However, even by day 42, bone mineral density (BMD) remained significantly lower, although serum hormones were back to normal. Because serum testosterone levels become undetectable in HLS rats, we hypothesized that the replacement of testosterone during HLS could prevent musculoskeletal losses. Based on these data, an intervention study was carried out to assess the efficacy of testosterone and synthetic anabolic steroid, nandrolone decanoate (ND), in prevention of weightlessness-induced musculoskeletal losses. HLS rats (control) had a significant reduction of muscle volume (42.9 -/+ 3.0, versus 56 -/+ 1.8 in ground control rats; p<0.01). Both testosterone and ND treatments prevented this muscle loss (51.5 -/+ 2 cm(3) and 51.6 -/+ 1.2, respectively; a 63% improvement, p<0.05). Similarly, BMD of the placebo-treated HLS rats was significantly lower than that of ground control rats (0.416 -/+ 0.011 versus 0.354 -/+0.014, p<0.05), and testosterone and ND prevented this bone loss (0.404 -/+ 0.013 versus. 0.409 -/+ 0.011, respectively). These data suggest that both testosterone and ND therapy can minimize the musculoskeletal losses associated with exposure to simulated weightlessness. Experiments using the combination of bisphosphonate and testosterone demonstrated complete protection of both muscle and bone in these HLS rats

    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.

    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

    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.

    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.

Raloxifene (Evista) decreases the incidence of positive estrogen receptor breast cancer and could prevent cardiovascular events in patients at high risk. Strontium ranelate (Protélos) prevents hip fracture in elderly women. The action of alendronate (Fosamax) on bone mineral density and markers of bone remodelling is of higher amplitude than that of risedronate (Actonel). Once monthly ibandronate (Bonviva) increases bone mineral density in post menopausal women with osteoporosis. Excessive suppression of bone remodelling and osteonecrosis of the yaws could be related to bisphosphonate intake.

    Antipsychotic drugs have been used to treat patients with schizophrenia and other psychotic disorders. Long-acting injectable antipsychotic drugs are useful for improving medication compliance with a better therapeutic option to treat patients who lack insight or adhere poorly to oral medication. Several long-acting injectable antipsychotic drugs are clinically available. Haloperidol decanoate and fluphenazine decanoate are first-generation depot drugs, but the use of these medicines has declined since the advent of second-generation depot agents, such as long-acting risperidone, paliperidone palmitate, and olanzapine pamoate. The second-generation depot drugs are better tolerated and have fewer adverse neurological side effects. Long-acting injectable risperidone, the first depot formulation of an atypical antipsychotic drug, was prepared by encapsulating risperidone into biodegradable microspheres. Paliperidone palmitate is an aqueous suspension of nanocrystal molecules, and olanzapine pamoate is a microcrystalline salt of olanzapine and pamoic acid suspended in aqueous solution. This review summarizes the characteristics and recent research of formulations of each long-acting injectable antipsychotic drug.

    As dental implants become a more accepted treatment modality, there is a need for all parties involved with implant dentistry to be familiar with various treatment planning issues. Though the success can be highly rewarding, failure to forecast treatment planning issues can result in an increase of surgical needs, surgical cost, and even case failure. In this issue, the focus is on implant treatment planning considerations.

  10. In vivo MRI evaluation of anabolic steroid precursor growth effects in a guinea pig model.

    PubMed

    2009-08-01

    Anabolic steroids are widely used to increase skeletal muscle (SM) mass and improve physical performance. Some dietary supplements also include potent steroid precursors or active steroid analogs such as nandrolone. Our previous study reported the anabolic steroid effects on SM in a castrated guinea pig model with SM measured using a highly quantitative magnetic resonance imaging (MRI) protocol. The aim of the current study was to apply this animal model and in vivo MRI protocol to evaluate the growth effects of four widely used over-the-counter testosterone and nandrolone precursors: 4-androstene-3 17-dione (androstenedione), 4-androstene-3beta 17beta-diol (4-androsdiol), 19-nor-4-androstene-3beta-17beta-diol (bolandiol) and 19-nor-4-androstene-3 17-dione (19-norandrostenedione). The results showed that providing precursor to castrated male guinea pigs led to plasma steroid levels sufficient to maintain normal SM growth. The anabolic growth effects of these specific precursors on individual and total muscle volumes, sexual organs, and total adipose tissue over a 10-week treatment period, in comparison with those in the respective positive control testosterone and nandrolone groups, were documented quantitatively by MRI.

  11. Use of anabolic-androgenic steroids masking the diagnosis of pleural tuberculosis: a case report

    PubMed Central

    2009-01-01

    Introduction Tuberculous pleural effusions are not always easy to diagnose but the presence of a lymphocyte-rich exudate associated with an increased adenosine deaminase level and a positive skin test result are highly sensitive diagnostic signs. Case presentation We report a case of pleural tuberculosis in a 31-year-old white male patient from Caracas, Venezuela who was negative for human immunodeficiency virus and presented 2 weeks after injecting the anabolic-androgenic steroid nandrolone decanoate, in whom all the tests for tuberculosis were initially negative; an eosinophilic pleural effusion with a low adenosine deaminase level, a negative tuberculin skin test and negative for acid-fast bacilli staining and culture of the pleural fluid. After excluding other causes of eosinophilic pleural effusion malignant pleural effusion was suspected. The patient did not return until 4 months later. The second thoracentesis obtained a pleural fluid suggestive for tuberculosis, with a predominance of lymphocytes, an elevated adenosine deaminase level (51 U/l) and a positive tuberculin skin test. Culture of pleural fragments confirmed pleural tuberculosis. Conclusion This case suggests that the use of an anabolic-androgenic steroid masks the definitive diagnosis of pleural tuberculosis by changing the key diagnostic parameters of the pleural fluid, a finding not previously reported. Available evidence of the effects of anabolic steroids on the immune system also suggests that patients using anabolic-androgenic steroids might be susceptible to developing tuberculosis in either reactivating a latent infection or facilitating development of the disease after a recent infection.

    Long-acting injectable risperidone was assessed in schizophrenia patients who were symptomatically stable on conventional depot antipsychotics and who were then switched to long-acting risperidone. Participants in this open-label, multicentre, 12-week trial had received flupenthixol decanoate, fluphenazine decanoate, haloperidol decanoate, or zuclopenthixol decanoate for 4 months or longer. Each was considered symptomatically stable by investigators. After receiving two cycles of their conventional depot antipsychotic during the run-in period, patients were switched to receive long-acting risperidone every 2 weeks for 12 weeks at an initial dose of 25 mg. This dose could be increased in 12.5-mg increments at 4-week intervals. Ninety-two percent of the patients received all six injections; 62% received the 25-mg dose throughout the treatment period. Adverse events related to movement disorders were reported in 3%. Severity of movement disorders decreased during long-acting risperidone treatment. Positive and Negative Syndrome Scale (PANSS) total and factor scores and scores on the Clinical Global Impressions severity scale were significantly reduced during treatment; 48% of these stable patients showed further symptom improvement (> or =20% decrease in PANSS score at endpoint). The results indicate that patients with schizophrenia who are symptomatically stable during treatment with a conventional depot antipsychotic can be safely and effectively switched to long-acting injectable risperidone without a prior transition to oral risperidone.

  14. Treatment of bipolar disorder

    PubMed Central

    2013-01-01

    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

  15. Treatment for morbid obesity

    PubMed Central

    Carmichael, A

    1999-01-01

    There is no single unifying theory to explain the aetiology of obesity but several environmental factors, such as decreased physical activity and increased fat intake may contribute to its development in genetically predisposed individuals. Dietary and pharmacological treatments of morbid obesity have been proven to be unsuccessful. Modern surgical treatments have been shown to be effective in achieving significant weight loss with consequent reduction in morbidity. Despite the fact that surgical treatment of morbid obesity is the only therapeutic form that has stood the test of time, it still remains a crisis-driven form of therapy in the UK. It is probable that a better understanding of the aetiology and physiology of obesity may lead to the development of an effective pharmacological treatment of obesity in the future. However, until then, surgical treatment of morbid obesity should be considered as an effective and efficient way of treatment in selected cases.

    Water and wastewater utilities face major changes in their treatment systems as a result of recent environmental regulations. Not only do these new rules specify reduction requirements for contaminants not previously regulated, they also target the by-products of chlorination, which has been the basic disinfection technique in this country since the early days of municipal water treatment. As a result, EPRI has been working with the American Water Works Association Research Foundation and the Water Environment Research Foundation to support the development of advanced treatment alternatives and improve energy efficiency at treatment facilities. The work has identified a number of innovative, electrically based treatment technologies that provide the additional capabilities required, promote higher efficiency in treatment processes, and serve electric utilities' demand-side management objectives. 5 refs.

While in vasculitis of large vessels treatment with gluccocorticoids is often sufficient, in ANCA associated vasculitis almost always intial combination of gluccocorticoids and immunosupresive drugs (cyclofosfamide in severe forms; azatioprin and metotrrexate in moderate disease) is needed. Maintance therapy of ANCA associated vasculitis is methotrexate or azatioprin. From biologic therapy, in gigantocellular vasculitis treatment with tocilizumb has a great expectation, while in ANCA associated vasculitis recently rituximab was approved by regulatory agencies, and it is nontinferior to cyclofosfamide in induction of remission and prefarable in relapsing disease.

Patients must always be informed that it is long and difficult and that no significant response will be expected before 2 to 3 months of regular treatment. The authors present the different therapeutic agents and strategies. Isotretinoin should be used only in severe acne after failure of at least 3 months of a well conducted classical treatment and in nodulo-cystic acne; because of its major side effect of teratogenicity its use in adolescent girl's requires pregnancy testings before and during treatment and an effective contraception.

It is usually caused by a growth hormone secreting pituitary adenoma and is manifested by a variety of clinical features. Surgery is usually the treatment of choice, however over the last few years, several new methods of treatment have been developed. A recent consensus on the targets for treatment has led to multiple studies being conducted to assess the efficacy of the currently available options.

    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.

    The number of adults undergoing orthodontic treatment has increased strongly and the average age that adult patients undergo orthodontic treatment increased steadily although 3/4 is still younger than 27 years. In adults the facial skeletal pattern can only be changed in a very confined way, consequently in case of an abnormal skeletal pattern one has to choose between a combined orthodontic-surgical approach (which is the case in 18% of the patients) and a compromised orthodontic treatment, if necessary combined with other disciplines. It is still controversial whether tooth movement in adults is slower and more difficult than in adolescents. The same holds true for the risk for loss of periodontal support, for root resorption, for gnathologic problems and for relapse. As related to these variables there appears to be a large individual variation. Many adults show one or more problems in their dentition that may influence their orthodontic treatment. About 60% of the adult patients need a multidisciplinary approach. The development of implantology and of bone regeneration and bone grafting has lead to more combined treatments. The risks of such complex treatment plans are generally larger than those for more simple kinds of treatment. A very careful treatment planning and good communication between the different specialists is essential. Moreover the treatment plan with all its (dis)advantages has to be extensively discussed with the patient.

    2005-05-01

    Primary headache disorders are often accompanied by neck pain or other symptoms referable to neck muscles. Therefore, physical therapy and other physical treatments are commonly prescribed for headache management. A medical literature review was completed in order to gather information regarding the efficacy of selected physical modalities in the treatment of primary and cervicogenic headache disorders. After analyzing the collected data, expert opinions were developed regarding the utility and efficacy of selected physical modalities in the management of primary and cervicogenic headaches. Based on this review, the following four expert opinions are presented: physical therapy is more effective than massage therapy or acupuncture for the treatment of tension-type headache and appears to be most beneficial for patients with a high frequency of headache attacks. Physical therapy is most effective for the treatment of migraine when combined with other treatments such as thermal biofeedback, relaxation training and exercise. Chiropractic manipulation demonstrated a trend towards benefit in the treatment of tension-type headache, but evidence is weak. Chiropractic manipulation is probably more effective in the treatment of tension-type headache than it is in the treatment of migraine. In general, strong evidence is lacking regarding the efficacy of these treatments in reducing headache frequency, intensity, duration and disability in many commonly encountered clinical situations. Many of the published case series and controlled studies are of low quality. Physical treatments are unlikely to pose a significant risk, with the exception of high velocity chiropractic manipulation of the neck. Consideration must be given to financial costs and lost treatment opportunity by prescribing potentially ineffective treatment. In the absence of clear evidence regarding their role in treatment, physicians and patients are advised to make cautious and individualized judgments about

    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.

    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.

    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

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.

  6. [Biofeedback treatment for epilepsy].

    Pharmacological treatment is the mainstay for the treatment of epilepsy. However concerns regarding long-term side effects of drugs are increasingly voiced. Behavioral treatments including biofeedback, represents an alternative management option for the control of epilepsy. Biofeedback is a non-invasive bio-behavioral procedure through which patients can learn to gain psychophysiological control over seizures. This article will first overview seizure precipitation from a psychological perspective, and then introduce three major biofeedback treatments. Sensory motor rhythm (SMR) and slow cortical potential(SCP) biofeedback uses electroencephalographic parameters and are categorized as neurofeedback. Electrodermal activity (EDA) biofeedback focuses on modulation of peripheral sympathetic tone. The neural mechanisms underlying biofeedback treatment will be discussed in relation to thalamo-cortical regulation(of neural excitability across brain networks).

  7. Pediatric hepatitis B treatment

    2017-01-01

    Although the introduction of hepatitis B vaccine has been contributing to the reduction in the prevalence of hepatitis B virus (HBV) carriers worldwide, the treatment of children with chronic HBV infection is a challenge to be addressed. HBeAg seroconversion, which induces low replication of HBV, is widely accepted as the first goal of antiviral treatment in children with chronic hepatitis B. However, spontaneous HBeAg seroconversion is highly expected in children with chronic HBV infection. Therefore, the identification of children who need antiviral treatment to induce HBeAg seroconversion is essential in the management of chronic HBV infection. Guidelines and experts’ opinion show how to identify children who should be treated and how to treat them. If decompensated cirrhosis is absent, interferon-alpha is the first-line antiviral treatment. Nucleos(t)ide analogues (NAs), such as lamivudine, adefovir, entecavir and tenofovir, are also available for the treatment of children, although the approval age differs among them. If decompensated cirrhosis is present, NAs are the first-line antivirals. When the emergence of drug-resistant HBV variants is taken into consideration, entecavir (approved for age 2 years or older) and tenofovir (age 12 years or older), which have high genetic barriers, will play a central role in the treatment of HBV infection. However, the optimal duration of NA treatment and adverse events of long-term NA treatment remain unclear in children. In resource-constrained countries and regions, the financial burden of visiting hospitals, receiving routine blood examination and purchasing antiviral drugs is heavy. Moreover, there is no clear evidence that the induction of HBeAg seroconversion by antiviral treatment prevents the progression of liver disease to cirrhosis and hepatocellular carcinoma in children with chronic HBV infection. It is thus imperative to clarify the clinical impact of antiviral treatment in children with HBV infection. PMID

  8. Treatment of Thoracolumbar Fracture

    2015-01-01

    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.

  9. [Chronic migraine: treatment].

    PubMed

    Pascual, Julio

    2012-04-10

    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.

  10. Tridecanoin is anticonvulsant, antioxidant, and improves mitochondrial function.

    2016-07-14

    The hypothesis that chronic feeding of the triglycerides of octanoate (trioctanoin) and decanoate (tridecanoin) in "a regular non-ketogenic diet" is anticonvulsant was tested and possible mechanisms of actions were subsequently investigated. Chronic feeding of 35E% of calories from tridecanoin, but not trioctanoin, was reproducibly anticonvulsant in two acute CD1 mouse seizure models. The levels of beta-hydroxybutyrate in plasma and brain were not significantly increased by either treatment relative to control diet. The respective decanoate and octanoate levels are 76 µM and 33 µM in plasma and 1.17 and 2.88 nmol/g in brain. Tridecanoin treatment did not alter the maximal activities of several glycolytic enzymes, suggesting that there is no reduction in glycolysis contributing to anticonvulsant effects. In cultured astrocytes, 200 µM of octanoic and decanoic acids increased basal respiration and ATP turnover, suggesting that both medium chain fatty acids are used as fuel. Only decanoic acid increased mitochondrial proton leak which may reduce oxidative stress. In mitochondria isolated from hippocampal formations, tridecanoin increased respiration linked to ATP synthesis, indicating that mitochondrial metabolic functions are improved. In addition, tridecanoin increased the plasma antioxidant capacity and hippocampal mRNA levels of heme oxygenase 1, and FoxO1.

  11. 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.

  12. Treatment decisions under ambiguity.

    PubMed

    Berger, Loïc; Bleichrodt, Han; Eeckhoudt, Louis

    2013-05-01

    Many health risks are ambiguous in the sense that reliable and credible information about these risks is unavailable. In health economics, ambiguity is usually handled through sensitivity analysis, which implicitly assumes that people are neutral towards ambiguity. However, empirical evidence suggests that people are averse to ambiguity and react strongly to it. This paper studies the effects of ambiguity aversion on two classical medical decision problems. If there is ambiguity regarding the diagnosis of a patient, ambiguity aversion increases the decision maker's propensity to opt for treatment. On the other hand, in the case of ambiguity regarding the effects of treatment, ambiguity aversion leads to a reduction in the propensity to choose treatment.

    Acne is a disfiguring disease, occurring mainly in adolescence. It is a common disorder, affecting above 80% of adolescents in some degree. 50% wish to have treatment for the condition. Acne appears in many forms; from the more common comedonal and papulopustular types to the often devastating cystic and fulminant acne. Some patients develop disfiguring scarring and keloidal reactions, which persist for the rest of their lives. With the treatment facilities available in modern medicine, acne problems can be eliminated through topical and/or systemic treatment options.

    Childhood vitiligo differs from the adults by showing a higher incidence in females, segmental vitiligo being more common and less frequent association with other systemic autoimmune and endocrine disorders. Childhood vitiligo is often associated with a marked psychosocial and long lasting effect on the self-esteem of the affected children and their parents, hence an adequate treatment is very essential. Treatment of vitiligo is indeed a tough challenge for the dermatologists’ more so in the background of childhood vitiligo. Although multiple therapeutic modalities are available in the therapeutic armamentarium, not all can be used in children.

    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.

  16. Current treatments for scabies.

    Buffet, M; Dupin, N

    2003-04-01

    Scabies is a frequent interhuman ectoparasitic infection. Several treatments are available worldwide. There are local treatments: synthetic pyrethrins, benzyl benzoate, lindane, crotamiton. Recently a few studies were published concerning ivermectin, systemic antiparasitic agent use in onchocercosis treatment. We reviewed the literature with an evidence-based medicine method. We attempt to answer two questions in particular: what is the treatment of choice for common scabies in a patient otherwise in good health? What is the role of systemic ivermectin? We also report specific situations. Among local treatments, studies are heterogeneous according to products, countries, group of treated patients, with or without contact subjects, and the method of treatment application. There are very few high proof-level controlled studies. In France, a combination of benzyl benzoate 10% and sulfiram 2% is used most, according to professional consensus. The most studied product is the cream permethrin 5%, available in the USA and UK. Its efficacy seems slightly superior to lindane and less toxic. It is more efficient than crotamiton. There is no study comparing benzyl benzoate and permethrin. Concerning systemic ivermectin, five controlled studies showed its efficiency in common scabies. But its relative efficiency over local treatment has not been established. A few open studies showed its efficacy in institutional epidemic, profuse scabies and in HIV-positive patients. Local treatment of choice in common scabies remains to be determined among the four principal molecules. There is no study comparing permethrin or esdepallethrin to benzyl benzoate. In what cases should we prescribe crotamiton or lindane? Indication of ivermectin seems proved in common scabies and probably for HIV-positive patients. It remains to be determined if it should be prescribed in the first instance, be double or triple, be associated or not with local treatment. In case of keratotic scabies, ivermectin

    2015-05-01

    Until quite recently, clinical guidelines and reviews on the treatment of hyperhidrosis advised against the use of systemic therapies based on their unacceptable adverse effects and a lack of evidence of usefulness. Numerous studies published over the past few years, however, have shown that, when used appropriately, these treatments are effective and in general have a favorable tolerability profile, making them an additional option for the treatment of hyperhidrosis, particularly for disease that is widespread, multifocal, or resistant to other treatments. In this review, the first of its kind, we examine the systemic therapies available for hyperhidrosis, including antihypertensives, psychoactive agents, and in particular oral anticholinergics, although none of these drugs are currently approved for this indication.

    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.

    2011-01-01

    Cutaneous lupus erythematosus (CLE) is an autoimmune, inflammatory skin disease seen in patients with or without systemic lupus erythematosus (SLE). The management of CLE includes treatment and prevention of lesions, as well as routine assessment for systemic disease. Treatment options include both topical and systemic therapies. Topical therapies include corticosteroids and calcineurin inhibitors. Systemic therapies generally fall under one of three categories: antimalarials, immunomodulators, such as dapsone and thalidomide, and immunosuppressives, such as methotrexate and mycophenolate. Evidence for the treatment of CLE is limited by few prospective studies, as well as lack of a validated outcome measure up until recently. There is good evidence to support the use of topical steroids and calcineurin inhibitors, though most of these trials have not used placebo or vehicle controls. There have been no randomized placebo-controlled trials evaluating systemic therapies for the treatment of CLE. PMID:21503694

    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.

    Ganglion cysts are soft tissue swellings occurring most commonly in the hand or wrist. Apart from swelling, most cysts are asymptomatic. Other symptoms include pain, weakness, or paraesthesia. The two main concerns patients have are the cosmetic appearance of the cysts and the fear of future malignant growth. It has been shown that 58% of cysts will resolve spontaneously over time. Treatment can be either conservative or through surgical excision. This review concluded that nonsurgical treatment is largely ineffective in treating ganglion cysts. However, it advised to patients who do not surgical treatment but would like symptomatic relief. Compared to surgery, which has a lower recurrence rate but have a higher complication rate with longer recovery period. It has been shown that surgical interventions do not provide better symptomatic relief compared to conservative treatment. If symptomatic relief is the patient's primary concern, a conservative approach is preferred, whilst surgical intervention will decrease the likelihood of recurrence.

    Somnambulism is an arousal disorder that is usually benign, self-limited and only infrequently requires treatment. Chronic sleepwalking in children has been shown to be associated with behavioral problems and poor emotional regulation. Most cases can be diagnosed with careful noting of case history and epilepsy is an important differential diagnosis. Management with pharmacological and behavioural measures is usually safe and effective. We present two cases of somnambulism that highlight the importance of the diagnosis and treatment of this condition.

    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.

  20. Laser treatment in gynecology

    de Riese, Cornelia

    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.

    Surface plays a crucial role in biological interactions. Surface treatments have been applied to metallic biomaterials in order to improve their wear properties, corrosion resistance, and biocompatibility. A systematic review was performed on studies investigating the effects of implant surface treatments on biocompatibility. We searched the literature using PubMed, electronic databases from 1990 to 2009. Key words such as implant surface topography, surface roughness, surface treatment, surface characteristics, and surface coatings were used. The search was restricted to English language articles published from 1990 to December 2009. Additionally, a manual search in the major dental implant journals was performed. When considering studies, clinical studies were preferred followed by histological human studies, animal studies, and in vitro studies. A total of 115 articles were selected after elimination: clinical studies, 24; human histomorphometric studies, 11; animal histomorphometric studies, 46; in vitro studies, 34. The following observations were made in this review: · The focus has shifted from surface roughness to surface chemistry and a combination of chemical manipulations on the porous structure. More investigations are done regarding surface coatings. · Bone response to almost all the surface treatments was favorable. · Future trend is focused on the development of osteogenic implant surfaces. Limitation of this study is that we tried to give a broader overview related to implant surface treatments. It does not give any conclusion regarding the best biocompatible implant surface treatment investigated till date. Unfortunately, the eventually selected studies were too heterogeneous for inference of data.

  2. Prophylactic Treatment of Migraine

    2013-01-01

    Migraine is a common chronic neurological disease characterized by episodic attacks of headache and associated symptoms. The pharmacological treatment of migraine may be acute or prophylactic, and patients with frequent, severe headaches often require both approaches. Prophylactic treatment is used to reduce the frequency, duration, or severity of attacks, to enhance the benefits of acute treatments, and to improve patient’s ability to function normally. Prophylactic treatment may also prevent progression from episodic migraine to chronic migraine and may result in reductions in health-care cost. The currently available pharmacological options for migraine prophylaxis include a wide array of medications. The major medication groups for prophylactic treatment include β-blockers, anticonvulsant, drugs such as topiramate and valproate, antidepressant drugs, such as amitriptyline and selective serotonin and selective serotonin-norepinephrine reuptake inhibitors (SNRIs), calcium channel antagonists and neurotoxins. The agent for prophylactic treatment should be chosen based on the efficacy and side-effect profile of the drug, and the patient’s coexistent and comorbid conditions.

  3. Drug treatment of hyperprolactinemia.

    PubMed

    Chanson, P; Borson-Chazot, F; Chabre, O; Estour, B

    2007-06-01

    Medical treatment of hyperprolactinemia is based upon use of dopamine agonists (DA): bromocriptine, lisuride, quinagolide and cabergoline. In over 80% of cases, these drugs induce normal prolactinemia and ovulatory cycles. In resistant cases, the DA should be changed. Tolerance may occasionally be poor, particularly with bromocriptine, which appears less well-tolerated than quinagolide and than cabergoline above all. In the event of intolerance to a given DA, another should be tried. In patients with macroprolactinoma treated with DA, MRI monitoring should be carried out after 3 months of treatment to verify tumor size reduction, then after 1 year, yearly for the next 5 years and once every 5 years if adenoma size is stable. In cases of microprolactinoma, control under treatment is pointless. MRI may be performed after 1 year and then after 5 years. Once normal prolactin levels have been achieved, attempts may be made to stop the treatment. When a prolonged treatment is interrupted, especially with cabergoline, progressive increase in serum prolactin and return of hyperprolactinemia symptoms are seen in only around 20-30% of cases, particularly when residual adenoma exists after prolonged treatment. Nevertheless, prolactin levels should continue to be monitored after discontinuation of DA, possibly with MRI monitoring, since prolactin levels may rise again after a number of months or years. When normal prolactin levels have been achieved with DA, another solution consists in reducing the dose or dosing frequency of DA in steps to the lowest effective dose consistent with maintenance of normal prolactin levels and stable adenoma size. For drug-induced hyperprolactinemia, where the causative medication cannot be withdrawn, it is often pointless and possibly even dangerous to administer a DA. It is therefore necessary to check for absence of pituitary adenoma and where necessary, begin treatment with sex steroids so as to ensure satisfactory impregnation with sex

  4. Pharmacoeconomics of antibacterial treatment.

    PubMed

    Davey, P G; Malek, M M; Parker, S E

    1992-06-01

    Antibacterial drugs account for between 3 and 25% of all prescriptions, between 6 and 21% of the total market value of drugs in a single country, and up to 50% of the drug budget in hospitals. Bacterial infection is widely perceived as disease caused by harmful outside agents which can be isolated and tested to select the best drug for treatment. In fact, the need for any treatment and the pros and cons of different drugs are just as debatable as in any other therapeutic area. Moreover, the bacteria which make up the normal flora of the body fulfil important roles, so that the ecological implications of treatment for the individual and for society should be considered in assessing the costs and consequences of antibacterial treatment. In this review we outline the most important issues relating to the treatment of bacterial infection in the community and in the hospital, contrasting information from developed and developing countries where appropriate. We review the existing literature on economic evaluation, but in general most of the literature deals with containing the costs of antibacterial drugs in hospitals, and there are many gaps in the literature on cost-effectiveness of treatment. Consequently there are still extreme variations in medical practice which present a challenge for future evaluation. As the outcomes of antibacterial treatment are apparent in a few weeks or months, this is an ideal field for testing pharmacoeconomic methodology. The desire to overcome medical practice variation through consensus statements should be avoided. Instead we recommend wider application of decision analysis to acknowledge that choices exist for the diagnosis and treatment of bacterial infection and to gather information about the implications of these choices. Much of the existing literature would be improved by a more explicit definition of costs. Direct costs to the health services should be distinguished from non medical costs. Moreover, the analysis should

  5. Treatment preparatory to psychoanalysis.

    PubMed

    Bernstein, S B

    1983-01-01

    Many potentially analyzable adult patients with unimpaired egos require a period of preparatory treatment before entering psychoanalysis. There has been some concern that such face-to-face treatment, if done with the same analyst, would influence the subsequent analysis by stimulating inaccessible unconscious fantasies, gratifying infantile wishes, or making the analyst too "real." This would necessitate a change to another analyst after the preparatory treatment, in order that the analysis be unmodified and have the most profound and definitive effects. Increasingly, however, many analysts practicing in the classical tradition have found preparatory treatment compatible with progression to psychoanalysis with the same analyst. But neither this process nor the concerns about it have been described to any extent in the literature. This may be, in part, because of historical conceptions that the effects of psychotherapy rest mainly on suggestion, lack of a full theoretical framework for psychotherapy compared with psychoanalysis, and disagreement as to whether these procedures are dichotomous or on a continuum. In order to discuss most clearly the basic issues involved in preparatory treatment that progresses to analysis with the same analyst, a case is presented in which complex variables were at a minimum; the transition could be anticipated, so that interventions, which might complicate the analysis, could be avoided; and the preparatory treatment was necessary to attenuate specific resistances to the meaning of analysis. The patient described here resisted analysis as it represented the facilitator of a feared regression and the reactivator of warded-off libidinal and aggressive impulses and wishes which the patient experienced as more controllable in psychotherapy. The meanings and effects of the prior treatment and the transition on the analytic transference neurosis, resistances, countertransferences, as well as possible effects on analytic technique, are

  6. Treatment of Radiation Injury

    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

    2013-01-01

    Melanomas represent 4% of all malignant tumors of the skin, yet account for 80% of deaths from skin cancer.While in the early stages patients can be successfully treated with surgical resection, metastatic melanoma prognosis is dismal. Several oncogenes have been identified in melanoma as BRAF, NRAS, c-Kit, and GNA11 GNAQ, each capable of activating MAPK pathway that increases cell proliferation and promotes angiogenesis, although NRAS and c-Kit also activate PI3 kinase pathway, including being more commonly BRAF activated oncogene. The treatment of choice for localised primary cutaneous melanoma is surgery plus lymphadenectomy if regional lymph nodes are involved. The justification for treatment in addition to surgery is based on the poor prognosis for high risk melanomas with a relapse index of 50–80%. Patients included in the high risk group should be assessed for adjuvant treatment with high doses of Interferon-α2b, as it is the only treatment shown to significantly improve disease free and possibly global survival. In the future we will have to analyze all these therapeutic possibilities on specific targets, probably associated with chemotherapy and/or interferon in the adjuvant treatment, if we want to change the natural history of melanomas.

  8. Treatments for hidradenitis suppurativa.

    PubMed

    Andersen, R Kjærsgaard; Jemec, Gregor B E

    Hidradenitis suppurativa (HS) is not easily treated. Although not uncommon, HS is often misdiagnosed outside specialized clinics and inappropriately treated as a simple boil or abscess. In recent years, guidelines have been developed on the basis of expert opinion and the available literature. A multifaceted approach is necessary as HS lesions include both inflammation (amenable to medical treatment) as well as fibrosis (amenable to surgery only). The recommended antiinflammatory therapies encompass both antimicrobials and regular anti-inflammatory drugs. We have, therefore, reviewed treatments with the following agents: clindamycin, tetracycline, rifampicin, ertapenem, dapsone, triamcinolone, infliximab, adalimumab, and anakinra. The development of new medical treatments, however, is an ongoing effort, and important new data have been presented since the publication of the guideline. The current approach to the management of fibrotic lesions is surgery. It is important, as manifest fibrosis is generally not susceptible to medical treatment. Here minor excision, carbon dioxide-laser, and major surgery are discussed, and current evidence supporting their use is provided. A comprehensive three-pronged approach with adjuvant therapy, medical therapy, and surgery is recommended. The importance of adjuvant therapy, that is, pain management, wound care, and attention, is stressed. Adjuvant therapy not only plays a major role in patients' perception of a successful treatment but also is of practical importance to their coping and self-management. HS presents a significant unmet need, and this review provides a mechanistic update on the current real-world therapeutic option for the management of this distressing disease.

    PubMed

    2010-01-01

    Articles that update the state of knowledge regarding osteoporosis run the risk of quickly becoming obsolete because research and studies on osteoporosis today are arousing great interest among researchers, the pharmaceutical and medical equipment industries, governments and even WHO. 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.

    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 a 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.

    Abstract The past few decades have seen a number of medical breakthroughs that enabled the effective treatment of a range of conditions, transforming them from fatal into manageable ones. Examples include certain cancers and HIV. Conversely, progress on dementia has been limited. There are currently no treatments that will cure or even alter the progressive course of dementia, despite ongoing research investigating new therapies and care options. The UK Department of Health is interested in the potential to learn from other disease areas to better understand the particular social, economic, political, legislative and scientific contexts that have contributed to accelerating progress and breakthroughs in treatment. Such learning could helpfully inform dementia research and innovation efforts, and help identify levers for supportive policy development. This project analysed breakthroughs in the treatment of four selected conditions of ill health and seeks to identify potentially transferable lessons for the dementia context. Using evidence review and key informant interviews we sought to identify the series of “events” that eventually led to a given breakthrough, and the key milestones in the process that have helped improve understanding and potential for treatment. We also aimed to capture the temporal and causal relationships between “notable” events looking at a variety of factors implicated in the breakthrough pathway. The focus of this work was on political, economic, social, scientific and technological, and legal, regulatory and environmental factors. PMID:28083433

  13. Treatment options for insomnia.

    The frequency of sleep disruption and the degree to which insomnia significantly affects daytime function determine the need for evaluation and treatment. Physicians may initiate treatment of insomnia at an initial visit; for patients with a clear acute stressor such as grief, no further evaluation may be indicated. However, if insomnia is severe or long-lasting, a thorough evaluation to uncover coexisting medical, neurologic, or psychiatric illness is warranted. Treatment should begin with nonpharmacologic therapy, addressing sleep hygiene issues and exercise. There is good evidence supporting the effectiveness of cognitive behavior therapy. Exercise improves sleep as effectively as benzodiazepines in some studies and, given its other health benefits, is recommended for patients with insomnia. Hypnotics generally should be prescribed for short periods only, with the frequency and duration of use customized to each patient's circumstances. Routine use of over-the-counter drugs containing antihistamines should be discouraged. Alcohol has the potential for abuse and should not be used as a sleep aid. Opiates are valuable in pain-associated insomnia. Benzodiazepines are most useful for short-term treatment; however, long-term use may lead to adverse effects and withdrawal phenomena. The better safety profile of the newer-generation nonbenzodiazepines (i.e., zolpidem, zaleplon, eszopidone, and ramelteon) makes them better first-line choices for long-term treatment of chronic insomnia.

    2014-03-01

    Hirsutism is defined as excessive terminal hair growth in androgen-dependent areas of the body in women, which grows in a typical male distribution pattern. Hirsutism is a common clinical problem in women, and the treatment depends on the cause. The condition is often associated with a loss of self-esteem. Hirsutism reflects the interaction between circulating androgen concentrations, local androgen concentrations, and the sensitivity of the hair follicle to androgens. Polycystic ovary syndrome and idiopathic hirsutism are the most common causes of the condition. A woman's history and, physical examination are particularly important in evaluating excess hair growth. The vast majority of women with hirsutism have the idiopathic variety, and the diagnosis is made by exclusion. Serum testosterone level>200 ng/dL is highly suggestive of adrenal or ovarian tumor. Treatment of hirsutism should be based on the degree of excess hair growth presented by the patient and in the pathophysiology of the disorder. Treatment includes lifestyle therapies, androgen suppression, peripheral androgen blockage, and cosmetic treatments. The current review discusses definition, pathogenesis, physiopathology, differential diagnosis, diagnostic strategies, and treatment.

    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.

    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.

    The NIMH Treatment Strategies in Schizophrenia (TSS) collaborative study group investigated the efficacy of antisychotic drug maintenance strategies involving reduced medication exposure in interaction with applied and supportive family management for the long-term treatment of schizophrenia. Therapy was provided at five centers by 25 clinicians who did not participate in the development of the therapies. They were trained by two of the authors, I.R.H.F and C.W.M, in applied family management, a homebased treatment derived from the behavioral family therapy developed by them. Clinicians’ characteristics, selection, and training methods, as well as patient rehospitalization rates, are reported for the two family management conditions. The TSS study represents a bridge between the development of a novel therapy and its dissemination in general clinical practice. PMID:22700264

    This paper develops robust models for estimating and interpreting treatment effects arising from both ordered and unordered multistage decision problems. Identification is secured through instrumental variables and/or conditional independence (matching) assumptions. We decompose treatment effects into direct effects and continuation values associated with moving to the next stage of a decision problem. Using our framework, we decompose the IV estimator, showing that IV generally does not estimate economically interpretable or policy relevant parameters in prototypical dynamic discrete choice models, unless policy variables are instruments. Continuation values are an empirically important component of estimated total treatment effects of education. We use our analysis to estimate the components of what LATE estimates in a dynamic discrete choice model. PMID:27041793

    In this article the most frequent and interesting treatments for parasomnias are reviewed. Arousal disorders, REM sleep behavior disorders and nightmares, bruxism (which can occur in any sleep state) are considered. The pathophysiological mechanisms of parasomnias are unknown, explaining why there is rarely a specific treatment precipitating. Management depends on the patient's age, the frequency and intensity of the episodes, the familial structure, the presence of precipitating and risk factors, psychological disorders and the parasomnia itself. Different therapeutic approaches are described including (1), explanation and reassurance, (2) counselling to avoid precipitating factors such as irregular sleep patterns, alcohol or drug intake (3) strategies to avoid injury (4) psychological approaches such as behavioral therapies in some parasomnias such as nightmares or arousal disorders. However, very few controlled studies have been done making it difficult to provide recommendations based on controlled clinical trials. Pharmacologic treatments are rarely necessary except in REM sleep behavior disorders; they are most often needed for short term.

    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

    Gout is a commonly occurring medical condition that can lead to significant morbidity. Therapies available for the treatment of both acute and chronic gouty arthritis have not changed significantly since the 1960s. Although these treatments are well established, they are often contraindicated in the presence of various different comorbidities, including diabetes, renal insufficiency, hypertension and gastrointestinal disease, all of which can occur frequently in patients with gout. Therefore, new treatments are needed. This review describes recent advances in therapeutics for gout, including drugs designed to reduce levels of urate and to inhibit acute or chronic inflammation. While some of these strategies are currently available, others are undergoing regulatory evaluation or are at earlier stages of development.

    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.

    Kravets, Igor

    2016-03-01

    Hyperthyroidism is an excessive concentration of thyroid hormones in tissues caused by increased synthesis of thyroid hormones, excessive release of preformed thyroid hormones, or an endogenous or exogenous extrathyroidal source. The most common causes of an excessive production of thyroid hormones are Graves disease, toxic multinodular goiter, and toxic adenoma. The most common cause of an excessive passive release of thyroid hormones is painless (silent) thyroiditis, although its clinical presentation is the same as with other causes. Hyperthyroidism caused by overproduction of thyroid hormones can be treated with antithyroid medications (methimazole and propylthiouracil), radioactive iodine ablation of the thyroid gland, or surgical thyroidectomy. Radioactive iodine ablation is the most widely used treatment in the United States. The choice of treatment depends on the underlying diagnosis, the presence of contraindications to a particular treatment modality, the severity of hyperthyroidism, and the patient's preference.

  10. Treatment of Lyme borreliosis

    PubMed Central

    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

  11. Dynamic Treatment Effects.

    Heckman, James J; Humphries, John Eric; Veramendi, Gregory

    2016-02-01

    This paper develops robust models for estimating and interpreting treatment effects arising from both ordered and unordered multistage decision problems. Identification is secured through instrumental variables and/or conditional independence (matching) assumptions. We decompose treatment effects into direct effects and continuation values associated with moving to the next stage of a decision problem. Using our framework, we decompose the IV estimator, showing that IV generally does not estimate economically interpretable or policy relevant parameters in prototypical dynamic discrete choice models, unless policy variables are instruments. Continuation values are an empirically important component of estimated total treatment effects of education. We use our analysis to estimate the components of what LATE estimates in a dynamic discrete choice model.

  12. Epilepsy treatment and creativity.

    PubMed

    Zubkov, Sarah; Friedman, Daniel

    2016-04-01

    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".

  13. Enhanced industrial wastewater treatment

    1997-12-31

    The sodium sulfide/ferrous sulfate (SS/FS) process is a treatment technology for the reduction of hexavalent chromium and precipitation of heavy metals in industrial wastewater treatment plants (IWTP). When the ferrous ion, as ferrous sulfate, is mixed with sulfide, the hexavalent chromium is rapidly reduced to its trivalent state at a neutral pH and then precipitated. SS/FS technology can be used to replace the current hydroxide treatment chemistry in Navy IWTPs. This paper will present the results and lessons learned from full-scale implementation of SS/FS at Naval Undersea Warfare Center (NUWC) Keyport, Washington. The SS/FS treatment process reduced the chemical cost by fifty nine percent and sludge disposal cost by thirty one percent. On an annual basis total cost savings amounted to $31,950 or thirty four percent. The SS/FS treatment process lowered the amount of treatment chemicals used in the IWTP. Furthermore, metal sulfides tend to be two to three orders of magnitude less soluble than their corresponding metal hydroxides. This allows for cleaner effluent, which will help the facility meet environmental discharge requirements. Further benefits include the removal from the shop area of the high pressure sulfur dioxide cylinder (used in the hydroxide process), a faster and more reliable chrome reduction method, neutral pH operation that extends tank and equipment life, and less acid and caustic chemicals stored on the shop floor. As Navy activities respond to the ever increasing pressures to do more with less, the SS/FS process can help them meet the increasingly stringent standards.

    2015-03-01

    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.

    PubMed

    Traisman, Edward S

    2015-04-01

    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.

    Kounis syndrome is potentially a life-threatening medical emergency with both a severe allergic reaction and acute coronary syndrome. Most of the information about this syndrome has come from the case reports. The management of these patients may be challenging for clinicians, and unfortunately guidelines have not been established yet. In this article, we review the current guidelines of acute coronary syndromes and anaphylaxis along with the published cases with Kounis syndrome secondary to beta-lactam antibiotics. We have summarized our recommendations for the work-up and treatment of Kounis syndrome from available data. Obviously, larger prospective studies are needed to establish definitive treatment guidelines for these patients.

    Ayuk, John; Gittoes, Neil J L

    2014-04-01

    Serum magnesium concentration is determined by the interplay of intestinal absorption and renal excretion. Hypomagnesemia can occur as a result of insufficient magnesium intake, increased gastrointestinal or renal loss, or redistribution from extracellular to intracellular compartments. A number of drugs are known to cause hypomagnesemia, including proton pump inhibitors (PPIs). We report the case of a patient with symptomatic hypomagnesemia due to short bowel syndrome and PPI therapy. Investigations revealed low 24-hour urinary magnesium excretion and secondary hypocalcemia. PPI treatment was withdrawn and the patient was managed with intravenous and oral magnesium and calcium replacement. This teaching case provides an evidence-based discussion of the treatment of hypomagnesemia.

    Cosmetic products contribute to the efficacy of anti-acneic treatment. Cleaning bars without soap and lotions are to be preferred to soaps. Morning application of moisturizing creams compensate for dryness and irritation induced by topical treatment. Some of these cosmetic products may have a limited efficacy of the shiny appearance and/or acne lesions. Scrubs, abrasive sponges, masks and patches have a very limited usefulness. Make up and camouflage techniques are authorized, provided that the products have been tested non comedogenic and non acne-genic.

    Phillips, Karran A; Epstein, David H; Preston, Kenzie L

    2014-12-01

    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. This article is part of the Special Issue entitled 'CNS Stimulants'.

    1989-01-01

    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

    Engineered Damping Treatments (EDT) that have high damping characteristics per unit volume are presented. The EDT's under consideration, consist of cellular viscoelastic damping matrices with optimally selected cell configuration, size and distribution. The cellular topology of the EDT's is designed using Computer-Aided-Design (CAD) strategies and the obtained optimal configurations will be manufactured using the state-of-the-art technology of Rapid Prototyping (RP). The EDT's are modeled using the finite element method in an attempt to determine the optimal topologies that maximize the strain energy, maximize the damping characteristics and minimize the total weight. The CAD files of the prototypes of the EDT's. The damping characteristics of the manufactured EDT's are evaluated and compared with the corresponding characteristics obtained by conventional solid damping treatments in order to emphasize the importance of using optimally configured damping treatment to achieve high damping characteristics. The presented procedures are invaluable for designing efficient damping treatments for many military and civilian structures whose vibrations and noise must be effectively controlled.

    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).

    2012-01-01

    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

    2009-01-01

    Melasma is a common hypermelanotic disorder affecting the face that is associated with considerable psychological impacts. The management of melasma is challenging and requires a long-term treatment plan. In addition to avoidance of aggravating factors like oral pills and ultraviolet exposure, topical therapy has remained the mainstay of treatment. Multiple options for topical treatment are available, of which hydroquinone (HQ) is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin. Topical medications modify various stages of melanogenesis, the most common mode of action being inhibition of the enzyme, tyrosinase. Combination therapy is the preferred mode of treatment for the synergism and reduction of untoward effects. The most popular combination consists of HQ, a topical steroid, and retinoic acid. Prolonged HQ usage may lead to untoward effects like depigmentation and exogenous ochronosis. The search for safer alternatives has given rise to the development of many newer agents, several of them from natural sources. Well-designed controlled clinical trials are needed to clarify their role in the routine management of melasma. PMID:20101327

    2016-04-04

    We review a number of issues regarding missing data treatments for intervention and prevention researchers. Many of the common missing data practices in prevention research are still, unfortunately, ill-advised (e.g., use of listwise and pairwise deletion, insufficient use of auxiliary variables). Our goal is to promote better practice in the handling of missing data. We review the current state of missing data methodology and recent missing data reporting in prevention research. We describe antiquated, ad hoc missing data treatments and discuss their limitations. We discuss two modern, principled missing data treatments: multiple imputation and full information maximum likelihood, and we offer practical tips on how to best employ these methods in prevention research. The principled missing data treatments that we discuss are couched in terms of how they improve causal and statistical inference in the prevention sciences. Our recommendations are firmly grounded in missing data theory and well-validated statistical principles for handling the missing data issues that are ubiquitous in biosocial and prevention research. We augment our broad survey of missing data analysis with references to more exhaustive resources.

  9. Treatment Options for Narcolepsy.

    PubMed

    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.

    2014-09-01

    Urticaria is a common inflammatory skin disease. It is clinically defined as the occurrence of transient papular skin and/or mucosal lesions or subcutaneous lesions called angioedema. Chronic urticaria is defined as a clinical course over more than 6weeks. Different clinical forms of urticaria can coexist in the same patient. Urticaria results of mast cell activation. The diagnosis of urticaria is based on clinical examination. An allergic etiology for acute urticaria, although rare, is always to find and remove. Chronic urticaria is not allergic. Diagnosis is based on questioning and a careful clinical examination to rule out differential diagnoses. Few diagnostic tests are necessary for diagnosis and management, and are especially useful in case of doubtful diagnosis. The treatment of urticaria is symptomatic and based on anti-H1 second generation antihistamines as first-line therapy. In some chronic urticarial, antihistamines up dosing may be necessary. In the majority of patients, this treatment is sufficient to control chronic urticaria. In case of antihistamines failure, other treatment particularly immunomodulatory treatments can be offered in specialized departments.

  16. Drug treatment of haemorrhoids.

    2005-01-01

    Drug treatment for various anorectal conditions has been known since ancient times. Today, modern as well as traditional drugs are being increasingly used in all grades of symptomatic haemorrhoids. These drugs (oral and local) are used as a part of conservative management or as an adjuvant to invasive outpatient procedures. Flavonoids, in the new formulation of micronised purified flavonoid fraction (MPFF) or as part of the ancient traditional medicine derivative of the Ginkgo tree, are used for relief of acute symptoms (for control of bleeding and re-bleeding in all grades of haemorrhoids). MPFF has been recommended for control of acute bleeding in patients waiting for a definitive outpatient treatment. Similarly, better known drugs such as calcium dobisilate (used in diabetic retinopathy and chronic venous insufficiency), nitrates and nifedipine have also been effective and well tolerated in the medical treatment of haemorrhoids. However, drug treatment is not aimed at curing haemorrhoids. The prime objective of drug therapy is to control the acute phase (bleeding) so that definitive therapy (banding, injection sclerotherapy, infrared photocoagulation, cryotherapy or surgery) can be scheduled at a convenient time.

    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.

    PubMed

    Roy-Byrne, Peter

    2015-06-01

    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.

  11. [Treatment of pituitary adenomas].

    PubMed

    Mezosi, Emese; Nemes, Orsolya

    2009-09-27

    According to epidemiological studies, the prevalence of pituitary adenomas is 16.5% and the majority of them are "incidentalomas". The symptoms of pituitary disorders are often non-specific; disturbances of pituitary function, compression symptoms, hypophysis apoplexy or accidental findings may help the diagnosis. The hormonal evaluation of pituitary adenomas is different from the algorithm used in the disorders of peripheral endocrine organs. The first-line therapy of prolactinomas are the dopamine agonists, and the aims of the treatment are to normalize the prolactin level, restore fertility in child-bearing age, decrease tumor mass, save or improve the residual pituitary function and inhibit the relapse of the disease. The available dopamine agonists in Hungary are bromocriptine and quinagolide. In case of tumors with good therapeutic response, medical therapy can be withdrawn after 3-5 years; hyperprolactinemia will not recur in 2/3 of these patients. Neurosurgery is the primary therapy of GH-, ACTH-, TSH-producing and inactive adenomas. In the last decades, significant improvement has been reached in surgical procedures, resulting in low mortality rates. Acromegalic patients with unresectable tumors have a great benefit from somatostatin analog treatment. The growth hormone receptor antagonist pegvisomant is the newest modality for the treatment of acromegaly. The medical therapy of Cushing's disease is still based on the inhibition of steroid production. A new, promising somatostatin analog, pasireotide is evaluated in clinical trials. The rare TSH-producing tumor can respond to both dopamine agonist and somatostatin analog therapy. The application of conventional radiotherapy has decreased; radiotherapy is mainly used in the treatment of invasive, incurable or malignant tumors. Further studies are needed to elucidate the exact role of radiosurgery and fractionated stereotaxic irradiation in the treatment of pituitary tumors.

    Study Design Best evidence synthesis. Objective To identify, critically appraise, and synthesize literature from 1980 through 2006 on surgical interventions for neck pain alone or with radicular pain in the absence of serious pathologic disease. Summary of Background Data There have been no comprehensive systematic literature or evidence-based reviews published on this topic. Methods We systematically searched Medline for literature published from 1980 to 2006 on percutaneous and open surgical interventions for neck pain. Publications on the topic were also solicited from experts in the field. Consensus decisions were made about the scientific merit of each article; those judged to have adequate internal validity were included in our Best Evidence Synthesis. Results Of the 31,878 articles screened, 1203 studies were relevant to the Neck Pain Task Force mandate and of these, 31 regarding treatment by surgery or injections were accepted as scientifically admissible. Radiofrequency neurotomy, cervical facet injections, cervical fusion and cervical arthroplasty for neck pain without radiculopathy are not supported by current evidence. We found there is support for short-term symptomatic improvement of radicular symptoms with epidural corticosteroids. It is not clear from the evidence that long-term out comes are improved with the surgical treatment of cervical radiculopathy compared to non operative measures. However, relatively rapid and substantial symptomatic relief after surgical treatment seems to be reliably achieved. It is not evident that one open surgical technique is clearly superior to others for radiculopathy. Cervical foramenal or epidural injections are associated with relatively frequent minor adverse events (5%–20%); however, serious adverse events are very uncommon (<1%). After open surgical procedures on the cervical spine, potentially serious acute complications are seen in approximately 4% of patients. Conclusion Surgical treatment and limited

    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.

    Gout is an inflammatory joint disease associated with deposition of monosodium urate crystals in the bones forming the joints, in periarticular tissues and in other organs. The disease is one of the most frequent causes of disability. This paper presents the case of a 57-year-old male patient treated for generalised gout. A "clinical mask" suggesting another disease was the cause of making the correct diagnosis only six years after the occurrence of the first manifestations. The patient, with high values of inflammatory markers, severe pain and advanced joint destruction, was given an aggressive anti-inflammatory treatment. The unsatisfactory effect of the conservative treatment forced the authors to perform surgical resection of the gouty nodules in the hands. After several operations the function of the hand joints operated on, appearance of the hands and the quality of the patient's life improved significantly.

    2014-09-01

    Achalasia is a primary esophageal motility disorder, which shows distinct clinical, manometric, radiologic, and pathologic features. Available treatment strategies are pharmacological, endoscopic or surgical. In the past decades preferred treatment has alternated between surgical myotomy (presently Laparoscopic Heller Myotomy [LHM]) and endoscopic balloon dilation (EBD). While surgical myotomy promises superior long-term results and significantly less retreatment, endoscopic balloon dilation is initially far less invasive and yields comparable results after redilation. Peroral Endoscopic Myotomy (POEM) aims to combine the minimal invasive approach through the mouth with the better long-term results after LHM. Initial findings in the literature point to comparable success-rates after POEM and LHM. In the literature complication rates are similar to those obtained after surgery. This new interventional technique should be subject to randomized controlled trials and compared to EBD and LHM.

  19. Surgical Treatment of Epilepsy

    2013-01-01

    Purpose of Review: This article outlines indications for neurosurgical treatment of epilepsy, describes the presurgical workup, summarizes surgical approaches, and details expected risks and benefits. Recent Findings: There is class I evidence for the efficacy of temporal lobectomy in treating intractable seizures, and accumulating documentation that successful surgical treatment reverses much of the disability, morbidity, and excess mortality of chronic epilepsy. Summary: Chronic, uncontrolled focal epilepsy causes progressive disability and increased mortality, but these can be reversed with seizure control. Vigorous efforts to stop seizures are warranted. If two well-chosen and tolerated medication trials do not achieve seizure control, an early workup for epilepsy surgery should be arranged. If this workup definitively identifies the brain region from which the seizures arise, and this region can be removed with a low risk of disabling neurologic deficits, neurosurgery will have a much better chance of stopping seizures than further medication trials.

    Parasomnias are undesirable physical or experiential events that occur in and around sleep. Treatments include reassurance in some cases, various forms of cognitive-behavioral therapy (CBT), and pharmacologic agents. Cognitive restructuring, imagery rehearsal, relaxation, hypnosis, desensitization, and anticipatory awakenings are some of the common CBT and nonpharmacologic interventions. Medications that are used belong to a wide variety of pharmacologic classes, such as alpha-blockers (prazosin), tricyclic antidepressants (imipramine and clomipramine), selective serotonin reuptake inhibitors, benzodiazepines (diazepam and clonazepam), anticonvulsants (topiramate and gabapentin), desmopressin acetate, and anticholinergic agents (oxybutynin and tolterodine). Data on efficacy are only available from randomized trials on CBT and prazosin for nightmares and on pharmacologic and alarm therapy for enuresis. No large-scale randomized trials are available to assess the efficacy of the other treatments, and most data come from anecdotal case reports, case series, or small open-label trials.

    The authors focused on the current surgical treatment of resectable gastric cancer, and significance of peri- and post-operative chemo or chemoradiation. Gastric cancer is the 4th most commonly diagnosed cancer and the second leading cause of cancer death worldwide. Surgery remains the only curative therapy, while perioperative and adjuvant chemotherapy, as well as chemoradiation, can improve outcome of resectable gastric cancer with extended lymph node dissection. More than half of radically resected gastric cancer patients relapse locally or with distant metastases, or receive the diagnosis of gastric cancer when tumor is disseminated; therefore, median survival rarely exceeds 12 mo, and 5-years survival is less than 10%. Cisplatin and fluoropyrimidine-based chemotherapy, with addition of trastuzumab in human epidermal growth factor receptor 2 positive patients, is the widely used treatment in stage IV patients fit for chemotherapy. Recent evidence supports the use of second-line chemotherapy after progression in patients with good performance status PMID:24587643

    The story of the development of tacrine began from its synthesis as an intravenous antiseptic in 1940 by Adrian Albert in Australia. In the 1970's William Summers began using tacrine in treating drug overdose coma and delirium. He felt it might have application in Alzheimer's based on work done in England by Peter Davies. In 1981, Summers et al. gave intravenous tacrine to Alzheimer's patients showed measurable improvement. Between 1981 and 1986, Summers worked with Art Kling and his group at UCLA to demonstrate usefulness of oral tacrine in treatment of Alzheimer's patients. The average length of tacrine use in 14 completing patients was 12.6 months and improvement was robust. This sparked controversy in the field. In 1993, after larger studies replicated the positive effect of tacrine, it was approved by the US Food and Drug Administration for treatment of Alzheimer's disease.

    Based on estimates from the World Health Organization (WHO), there were 8.7 million new cases of tuberculosis (TB) and 1.4 million deaths globally in 2011. In Germany, TB has become a rare disease (incidence 5.3/100,000). Therefore, experience regarding the management and treatment of TB patients is decreasing. In this review, standard therapy of TB and the drugs administered are described. Prior to initiation of therapy, a thorough patient history must be taken to evaluate the risk factors for a drug-resistant TB. In addition, bacterial confirmation via microscopic and culture analyses and phenotypic drug susceptibility testing are also recommended. Treatment of TB is always based on combined antibiotic therapy. The selection of the drugs is determined by the resistance status of the strains. For detailed recommendations refer to the current recommendations of the German Central Committee against Tuberculosis e. V. (DZK) and the German Respiratory Society (DGP).

  4. 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.

    2014-07-01

    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.

    Migraine is one of the most frequent disabling neurological conditions with a major impact on the patient’s quality of life. Migraine has been described as a chronic disorder that characterized with attacks. Attacks are characterized by moderate–severe, often unilateral, pulsating headache attacks, typically lasting 4 to 72 hours. Migraine remains underdiagnosed and undertreated despite advances in the understanding of its pathophysiology. This article reviews management of migraine acute pharmacological treatment. Currently, for the acute treatment of migraine attacks, non-steroidal anti-inflammatory drugs (NSAIDs) and triptans (serotonin 5HT1B/1D receptor agonists) are recommended. Before intake of NSAID and triptans, metoclopramide or domperidone is useful. In very severe attacks, subcutaneous sumatriptan is first choice. The patient should be treated early in the attack, use an adequate dose and formulation of a medication. Ideally, acute therapy should be restricted to no more than 2 to 3 days per week to avoid medication overuse.

    PubMed

    Vennewald, Irina; Klemm, Eckart

    2010-03-04

    Aspergillus and Candida spp are the most frequently isolated fungi in patients with otomycosis. The diagnosis of otitis externa relies on the patient's history, otoscopic examination under microscopic control, and imaging studies. Direct preparation of the specimens, particularly with optical brighteners, mycologic culture, and histologic examination, is very important and strongly recommended for the correct diagnosis. Patients with noninvasive fungal otitis externa should be treated with intense débridement and cleansing, and topical antifungals. Topical antifungals, such as clotrimazole, miconazole, bifonazole, ciclopiroxolamine, and tolnaftate, are potentially safe choices for the treatment of otomycosis, especially in patients with a perforated eardrum. The oral triazole drugs, itraconazole, voriconazole, and posaconazole are effective against Candida and Aspergillus, with good penetration of bone and the central nervous system. These drugs are essential in the treatment of patients with malignant fungal otitis externa complicated by mastoiditis and meningitis.

    The acute cerebellar hematoma and the subdural hematoma resent urgent surgical problems and treatment early in the clinical course should result in an excellent outcome. The subdural hematoma may be especially difficult to diagnose early, but may be suspected in patients on anticoagulant therapy or with shunze, and surgery, especially in the acute stage, should be avoided if possible. The CT scan supplemented when necessary by angiography is the diagnostic procedure of choice and will clearly demonstrate the lesions.

  16. Delirium and its treatment.

    Delirium occurs at rates ranging from 10% to 30% of all hospital admissions. It is a negative prognostic indicator, often leading to longer hospital stays and higher mortality. The aetiology of delirium is multifactorial and many causes have been suggested. The stress-diathesis model, which posits an interaction between the underlying vulnerability and the nature of the precipitating factor, is useful in understanding delirium. Preventing delirium is the most effective strategy for reducing its frequency and complications. Environmental strategies are valuable but are often underutilized, while remedial treatment is usually aimed at specific symptoms of delirium. Antipsychotics are the mainstay of pharmacological treatment and have been shown to be effective in treating symptoms of both hyperactive and hypoactive delirium, as well as generally improving cognition. Haloperidol is considered to be first-line treatment as it can be administered via many routes, has fewer active metabolites, limited anticholinergic effects and has a lower propensity for sedative or hypotensive effects compared with many other antipsychotics. Potential benefits of atypical compared with typical antipsychotics include the lower propensity to cause over-sedation and movement disorder. Of the second-generation antipsychotics investigated in delirium, most data support the use of risperidone and olanzapine. Other drugs (e.g. aripiprazole, quetiapine, donepezil and flumazenil) have been evaluated but data are limited. Benzodiazepines are the drugs of choice (in addition to antipsychotics) for delirium that is not controlled with an antipsychotic (and can be used alone for the treatment of alcohol and sedative hypnotic withdrawal-related delirium). Lorazepam is the benzodiazepine of choice as it has a rapid onset and shorter duration of action, a low risk of accumulation, no major active metabolites and its bioavailability is more predictable when it is administered both orally and

    These studies were initiated to determine (1) if cisplatin (cis-DDP)-induced hyperglucagonemia is related to decreased hormone degradation, (2) the relationship between impaired kidney function associated with cis-DDP nephrotoxicity and hyperglucagonemia, and (3) the contribution of cis-DDP-induced hyperglucagonemia to disturbances in glucose metabolism in male F-344 rats. Administration of 5 or 7.5, but not 2.5, mg/kg cis-DDP iv increased fasting plasma immunoreactive glucagon (IRG) concentrations. Hyperglucagonemia following cis-DDP treatment was characterized by an increase in the biologically active or true pancreatic form of IRG as well as an increase in an extrapancreatic component. cis-DDP treatment (5 mg/kg) resulted in a prolonged half-life and a reduced rate of plasma disappearance of exogenous glucagon. Reducing cis-DDP nephrotoxicity, via mannitol pretreatment, resulted in a significant reduction in total, true pancreatic, and extrapancreatic plasma IRG. Other nephrotoxicants, such as glycerol or gentamicin, also resulted in hyperglucagonemia, indicating that the effects of cis-DDP on glucagon metabolism are also characteristic of other nephrotoxicants and, therefore, may be secondary to kidney toxicity. Despite marked hyperglucagonemia following cis-DDP treatment, neither severe fasting hyperglycemia nor increased hepatic and renal gluconeogenic enzyme activity was apparent in treated animals. This apparent discrepancy cannot be attributed to glucagon resistance at the target tissue level since cis-DDP-treated animals responded appropriately to exogenous glucagon. These results indicate that hyperglucagonemia following cis-DDP treatment (1) may be related to decreased glucagon degradation associated with impaired renal function and (2) does not markedly disrupt glucose homeostasis.

    Even before the recent development of biological agents, a long list of effective treatments has been available for patients with psoriasis. Topical therapies such as corticosteroids, vitamin D analogues, and retinoids are used for localised disease. Phototherapy including broadband ultraviolet B (UVB), narrowband UVB, PUVA, and climatotherapy are effective for more extensive disease. Systemic therapies such as methotrexate, retinoids, and ciclosporin are effective for patients with refractory or extensive cutaneous disease. PMID:15708945

    Strippings are problems that are frequent on thin and concave roots. Treatment and prognosis differ from that of a lateral root perforation because of the size, oval shape, and thin edges of the striping. We propose a two-step technique: an endodontic phase in which the root canal system is sealed with gutta-percha overflowing through the stripping perforation and a surgical second step that will allow elimination of this excess.

    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

    Laser treatments of various metals are studying depending on the laser wavelength, pulse time duration and shape, and fluence (laser/metal interaction regime). Low fluence excimer UV laser melting process of gold layer is shown to improve the corrosion resistance of multilayer (Au/Ni/Cu alloy) electrical contacts. For this application the homogenity of the laser beam as well as the initial Cu substrate roughness are found to be limiting parameters of the process. Carburization of Al alloy, performed in C3H6 atmosphere with a KrF laser induces the incorporation of carbon atoms over about 4 μm depth. The crystalline Al4C3 synthesized at the surface leads to a strengthening of the light Al alloy, which is of great interest for application in car industry. The study shows that diffusion of C atom in the target is possible because of a plasma presence on the surface which supports the molten bath life time and induces dissociation of the ambient gas. In the last example of laser metal surface treatment presented in that paper, a commonly used steel is treated in air with different lasers at a fluence above the plasma formation threshold. It is seen that the machining oils covering the surface before the treatment can be efficiently removed and that new compounds (nitride, carbide and oxides) are formed at the surface.

    The pharmacological treatment of obesity should be considered when cannot be achieved a 10% weight loss with diet therapy and physical activity. The drugs effective in obesity treatment may act by different mechanisms such as reduction in food intake, inhibition of fat absorption, increase of thermogenesis and stimulation of adipocyte apoptosis. At present, we only have two marketed drugs for obesity treatment. Sibutramine is an inhibitor of norepinephrine, dopamine and serotonina reuptake which inhibits food intake and increases thermogenesis. Sibutramine administration for a year can induce a weight loss of 4-7%. Its main side effects are hypertension, headache, insomnia and constipation. Orlistat is an inhibitor of pancreatic lipase which is able to block the absorption of 30% of ingested fat. Its administration induces weight loss and reduction of ulterior weight regain. Also, this drug improves hypertension dyslipdaemia and helps to prevent diabetes in 52% of cases when administered over four years. The increase in frequency of stools and interference with vitamin absorption are its main side effects. Glucagon-like peptide 1, which increases insulin sensitivity and satiety, adiponectin and PPAR-gamma agonists which reduce insulin resistance and modulates adipocyte generation are the basis for future therapeutic approaches of obesity. Phosphatase inhibitors induce PPAR-gamma phosphorylation and UCP-1 expression leading to an increase in thermogenesis and reduction in appetite.

    COPD treatment begins with smoking cessation and influenza and pneumococcal vaccines. Bronchodilators are indicated when dyspnea on exertion is reported (usually, FEV1 < 80% predicted). On-demand short-acting agents are chosen when dyspnea is intermittent, daily long-acting agents are administered once dyspnea occurs in daily life activities. In all cases, anticholinergics and beta2 agonists can be associated when one class is not sufficiently effective. In patients with FEV1 < 50% predicted (budesonide-formoterol) or 60% predicted (fluticasone-salmeterol), repeated exacerbations and symptoms despite maintenance bronchodilators, fixed associations are indicated. When a handicap persists on pharmacological treatment, respiratory rehabilitation centered on education and exercise training has to be proposed. Care for COPD has to integrate treatment of comorbidities such as cardio-vascular diseases, anxiety-depression, malnutrition, muscle dysfunction, osteoporosis, anemia ... Ongoing research aims at identifying new therapeutic targets, focusing on inflammation, remodeling, protease-antiprotease balance, oxidative stress, lung regeneration/repair and mucus production.

    Although compulsive buying is receiving increasing attention in research, it is largely ignored in clinical practice. Compulsive buying disorder (CBD) is defined as excessive and mostly senseless spending or excessive shopping impulses that cause marked distress, interfere with social or occupational functioning, and often results in financial problems. It is currently conceptualized as an "impulse control disorder not otherwise specified" (ICD-10 F63.9). CBD is associated with significant psychiatric co-morbidity particularly mood and anxiety disorders, obsessive-compulsive disorders, binge eating disorder, substance use disorders, personality disorders, and other impulse control disorders. Previous research indicates that many compulsive buyers also suffer from compulsive hoarding. There is no evidence-based treatment approach for CBD and treatment research on this topic is limited. Open label trials suggest that antidepressants could improve compulsive buying. However, small randomized controlled trials failed to demonstrate significant improvement over Placebo and the high placebo-response rate prevents any definitive statement on the efficacy of antidepressants. Two controlled cognitive-behavioral therapy (CBT) trials reported that group CBT is significantly more effective compared to waiting list control groups in the treatment of compulsive buying. Clinical and therapeutic implications are discussed.

    PubMed

    Pinals, R S

    1992-01-01

    Current pharmacotherapy for osteoarthritis (OA) is aimed at relief of pain and functional disability. Although an inflammatory component may be found in some cases, there is little evidence that anti-inflammatory drugs commonly used in the treatment of OA provide more relief than simple analgesics. A growing body of knowledge about the pathophysiology of OA now offers opportunities to develop interventions aimed at retarding the progressive degeneration of articular cartilage. This is a function of an imbalance between cartilage matrix synthesis and breakdown. New and experimental treatments include oral, parenteral, and intra-articular agents, some of which are chemicals and others biological products. Their modes of action have generally not been established in humans, but may be inferred from in vitro culture systems and animal models. These mechanisms include inhibition of synovial cell-derived cytokines and chondrocyte-derived degradative enzymes, inactivation of superoxide free radicals, stimulation of matrix synthesis, and enhancement of synovial fluid lubrication. Many of these treatments have been shown to provide short- or long-term symptomatic improvement in clinical trials. Protection of cartilage or promotion of repair has been demonstrated in animal studies, but not convincingly in human OA studies.

    The mystery of Traditional Chinese Medicine has been attracting people for years. Acupuncture, ranked among the most common services of Complementary and Alternative Medicine, has recently gained a lot of interest in the scientific world. Contemporary researchers have been continuously trying to shed light on its possible mechanism of action in human organism. Numerous studies pertaining to acupuncture’s application in cancer symptoms or treatment-related side effects management have already been published. Moreover, since the modern idea of acupuncture’s immunomodulating effect seems to be promising, scientists have propounded a concept of its potential application as part of direct anti-tumor therapy. In our previous study we summarized possible use of acupuncture in management of cancer symptoms and treatment-related ailments, such as chemotherapy-induced nausea and vomiting, pain, xerostomia, vasomotor symptoms, neutropenia, fatigue, anxiety, insomnia, lymphoedema after mastectomy and peripheral neuropathy. This article reviews the studies concerning acupuncture as a possible tool in modern anticancer treatment. PMID:28239282

    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

    Several subcutaneous and deep-seated mycoses are either observed more frequently in the tropical areas or are restricted to certain regions within the tropics. These mycoses include sporotichosis, chromoblastomycosis, entomophthoromycosis, eumycetoma, lobomycosis, and paracoccidioidomycosis. In sporotrichosis and paracoccidioidomycosis, therapy often results in either complete resolution or marked improvement. For decades sporotrichosis has been treated successfully with potassium iodide, but recently the triazole compounds, especially itraconazole, have proved effective and free of major side effects. The usual therapy for paracoccidioidomycosis is sulfonamides or amphotericin B; the former requires prolonged treatment, whereas the latter causes a significant degree of toxicity. Various azole derivatives (ketoconazole, fluconazole, saperconazole, and itraconazole) allow shorter treatment courses, can be given orally, and are more effective. Presently, itraconazole is the drug of choice. Chromoblastomycosis is a difficult condition to treat, especially if it is caused by Fonsecaea pedrosoi. Several therapeutic approaches have been used, including heat, surgery, cryotherapy, thiabendazole, amphotericin B combined with flucytosine, and azole derivatives, but their success has been modest. A 65% response rate has been obtained with itraconazole given for periods of 6 to 19 months; in limited trials, saperconazole appears to be more effective and requires shorter treatment courses. Only a few patients with eumycetoma respond to therapy; 70% of patients with Madurella mycetomatis respond to prolonged treatment with ketoconazole. Griseofulvin has been tried in nonresponders with partial success. Limited data in patients with Fusarium species eumycetoma indicate good responses to itraconazole. Eumycetoma caused by Pseudallescheria boydii or Acremonium species has been refractory to therapy. Therapy of entomophthoromycosis is also difficult because the diagnosis is usually

    PubMed

    Hain, Timothy C; Uddin, Mohammed

    2003-01-01

    This review discusses the physiology and pharmacological treatment of vertigo and related disorders. Classes of medications useful in the treatment of vertigo include anticholinergics, antihistamines, benzodiazepines, calcium channel antagonists and dopamine receptor antagonists. These medications often have multiple actions. They may modify the intensity of symptoms (e.g. vestibular suppressants) or they may affect the underlying disease process (e.g. calcium channel antagonists in the case of vestibular migraine). Most of these agents, particularly those that are sedating, also have a potential to modulate the rate of compensation for vestibular damage. This consideration has become more relevant in recent years, as vestibular rehabilitation physical therapy is now often recommended in an attempt to promote compensation. Accordingly, therapy of vertigo is optimised when the prescriber has detailed knowledge of the pharmacology of medications being administered as well as the precise actions being sought. There are four broad causes of vertigo, for which specific regimens of drug therapy can be tailored. Otological vertigo includes disorders of the inner ear such as Ménière's disease, vestibular neuritis, benign paroxysmal positional vertigo (BPPV) and bilateral vestibular paresis. In both Ménière's disease and vestibular neuritis, vestibular suppressants such as anticholinergics and benzodiazepines are used. In Ménière's disease, salt restriction and diuretics are used in an attempt to prevent flare-ups. In vestibular neuritis, only brief use of vestibular suppressants is now recommended. Drug treatments are not presently recommended for BPPV and bilateral vestibular paresis, but physical therapy treatment can be very useful in both. Central vertigo includes entities such as vertigo associated with migraine and certain strokes. Prophylactic agents (L-channel calcium channel antagonists, tricyclic antidepressants, beta-blockers) are the mainstay of treatment

It divided the treatment types into three classifications based on the severity of the carious lesions or injury. Treatments that are not usually found in current textbooks were outlined and commented upon.

    Severe infections are uncommon following orthopedic surgery, yet they can be frustrating for the veterinarian and owner to treat and can result in devastating consequences for the patient. This article reviews the common causes for postoperative infection, reviews established treatment, and introduces newer methods for treatment and control. A thorough understanding of the pathogenesis, application of appropriate diagnostic procedures, the institution of aggressive treatment regimens, with adherence to established principles, will often result in satisfactory outcomes even with severe orthopedic infections. For those more refractory to treatment, the use of newer treatment methods, specifically locally implantable materials for sustained release of antimicrobials can improve success in the treatment of these more difficult cases.

    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.

    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.

    The main clinical types of epilepsy and their treatment are described. The treatment of choice in petit mal epilepsy is trimethadione (Trimedone) 0.3 g., three to six times a day, or acetazolamide (Diamox) 125-250 mg., three to four times a day. Phenobarbital is usually given as well to prevent grand mal seizures. Diphenylhydantoin sodium (Dilantin Sodium), 100 mg., and/or phenobarbital, 30-100 mg., three to four times a day, is recommended in patients with focal and grand mal epilepsy. Psychomotor automatisms are a form of focal seizure. Primidone (Mysoline), in doses of 125-250 mg. two to three times a day, is a very useful anticonvulsant in patients with myoclonic features, psychomotor automatisms and grand mal seizures. Primidone should be started in small doses. Drug reactions, especially cerebellar ataxia in the case of diphenylhydantoin and blood dyscrasias in the case of some drugs, should be recognized. Excessive drowsiness can be avoided by proper dosage and proper timing of drug administration. Patients should be seen regularly at least two to three times a year. The objective of treatment is to achieve optimum control of seizures by using the appropriate drug in adequate dosage. Social adaptation is good in the majority of patients, who should be encouraged to carry on their life independently, usually free to marry and have children. Attention to special occupational hazards has to be considered. Education of employers and employees is often necessary. Special work arrangements are occasionally indicated for selected patients. Patients should be seizure-free for two to three years before permission is given to drive an automobile. PMID:13969008

    Vaginal or vulvovaginal atrophy is a widespread but poorly recognized condition of peri- and post-menopausal women. It causes urogenital symptoms of dryness, reduced lubrication, itching, burning, irritable bladder symptoms and painful intercourse. This impacts quality of life and sexual health, but increases with time rather than reduces, as with most other menopausal symptoms. With early identification, treatments can improve these symptoms and reverse the physical changes. However, when embedded, bladder and sexual changes have occurred and these may be more difficult to remedy. Therefore, it is important to educate both healthcare professionals and women about these symptoms and advise on the range of interventions available.

    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.

    The effective treatment of acute (myeloblastic and lymphoblastic) leukaemias depends on the induction of remissions as well as on the maintenance of these remissions. Whereas the use of anthracyclines and of cytosine arabinoside in different combinations notably increased the rate of induction of remissions, their maintenance was less successful until now. We present a scheme using, beside MTX and 6-MP, modified COAP regimes periodically every 3 months. The follow-up of 26 patients treated in this way is encouraging since nearly one third remained in full haematological remission after 3 years of observation.

    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.

  3. Treatment for alopecia.

    Satisfactory, evidence-based medicine regimen for treating alopecia are available in literature only regarding alopecia areata and androgenetic alopecia. 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.

    Melasma, a hypermelanosis of the face, is a common skin problem of middle-aged women of all racial groups, especially with dark complexion. Its precise etio-pathogenesis is evasive, genetic influences, exposure to sunlight, pregnancy, oral contraceptives, estrogen-progesterone therapies, thyroid dysfunction, cosmetics, and drugs have been proposed. Centro-facial, malar, and mandibular are well-recognized. Epidermal pigmentation appears brown/black, while dermal is blue in color, and can be distinguished by Wood's lamp illumination. The difference may be inapparent with mixed type of melasma in skin types V and VI. An increase in melanin in epidermis: basal and suprabasal layers and/or dermis is the prime defect. There is an increased expression of tyrosinase related protein-1 involved in eumelanin synthesis. The use of broad-spectrum sunscreen is important, lightening agents like retinoic acid (tretinoin), azelaic acid, and combination therapies containing hydroquinone, tretinoin, and corticosteroids, have been used in the treatment of melasma, and are thought to have increased efficacy as compared with monotherapy. Quasi-drugs, placental extracts, ellagic acid, chamomilla extract, butylresorcinol, tranexamic acid, methoxy potassium salicylate, adenosine monophosphate disodium salt, dipropyl-biphenyl-2,2'-diol, (4-hydroxyphenyl)-2-butanol, and tranexamic acid cetyl ester hydrochloride, in addition to kojic and ascorbic acid have been used. Chemical peeling is a good adjunct. Laser treatment is worthwhile.

    At the No Treatment Day School, less than 15% of students used the dormitory during the school week. Located in the heart of a reservation and serving local students, the K-12 school enrolled over 1,000 students. The site received Therapeutic Residential Model funding for the 2001-2002 school year. Initial evaluation of this site found an array of daunting problems throughout the school structure and functioning. There were some successes, including implementation of the Morningside reading program in the elementary school and some response from the community to the comprehensive evaluation report which provided an overview of the situation to policy-makers and community members. However instability in the system and a mid-year change in leadership complicated the process of implementation. By the end of the first year, it was clear that the feasibility of the original proposal was questionable and that an overhaul of the school's system and culture was necessary before a Therapeutic Residential Model could be implemented or significant change could come about. Therapeutic Residential Model funding was terminated at the end of the school year. As there was no substantial implementation of a Therapeutic Residential Model program, data gathered were utilized as representing a naturally occurring control or minimal treatment site.

    Systemic lupus erithematosus (SLE) is a multiorganic inflammatory disease characterized by a significant morbidity and mortality related not just to disease evolution but also to therapeutic side effects. Sixty percent of SLE patients develop renal disease related to lupus. Moreover, several studies report that lupus nephritis is an important predictor of both renal impairment and global mortality in these patients. In lupus nephritis, the renal biopsy still represents a cornerstone for both histological grading and therapeutical management. Several classification schemes for lupus nephritis based mainly on morphological parameters have been proposed so far. In the WHO grading system the most severe form of lupus nephritis is the diffuse proliferative lupus nephritis or lupus nephritis class IV. In fact, several authors have documented an invariable course to end stage renal failure in these patients, in the absence of specific therapy. Despite the considerable improvement observed since the introduction of corticosteroid and cyclophosphamide treatment, a significant number of patients still present an incomplete response to therapy. Moreover, even in the cases of good response to therapy adverse events related to the treatment such as infertility, hemorrhagic cystitis or increased susceptibility to infection frequently supervenes.

  7. Teratogenesis and immunosuppressive treatment.

    Despite the potential risks to the mother and fetus caused by immunosuppressive drugs, uneventful pregnancies are now frequent among transplant recipients. Although there is no apparent increase in the type or incidence of malformations in the newborns or evidence of graft dysfunction, pregnancy-related complications, including premature termination and low birth weight, may be more frequent. To prevent graft rejection due to the increased immunologic reactivity of the transplant recipient during pregnancy, it is reasonable to wait 2 years after transplantation before conception, to have stable graft function and to be on low drug doses for maintenance immunosuppression. Among the immunosuppressive agents, corticosteroids may induce a number of treatment-related complications, including diabetes and osteoporosis; however, the incidence of fetal malformations during corticosteroid treatment is about 3.5%, a value close to that of the general population. Among immunosuppressive antibodies, no evidence of developmental toxicity has been demonstrated with basiliximab. On the contrary, some concerns have been raised about azathioprine, since its use has been associated with fetal abnormalities in animals; however, clinical data so far have indicated only a small teratogenic risk. Therefore, immunosuppressive therapy with selected drugs and antibodies does not apparently increase the risk of birth defects and may be continued in pregnancy. Finally, although breast-feeding is not recommended, because of drug transfer into maternal milk, the available clinical data do not support this limitation because of the low amount of drug absorbed by the infant and the absence of clinical toxicity in published case reports.

    2014-01-01

    Huntington's disease (HD) is a dominantly inherited progressive neurological disease characterized by chorea, an involuntary brief movement that tends to flow between body regions. HD is typically diagnosed based on clinical findings in the setting of a family history and may be confirmed with genetic testing. Predictive testing is available to family members at risk, but only experienced clinicians should perform the counseling and testing. Multiple areas of the brain degenerate, mainly involving the neurotransmitters dopamine, glutamate, and γ-aminobutyric acid. Although pharmacotherapies theoretically target these neurotransmitters, few well-conducted trials for symptomatic interventions have yielded positive results and current treatments have focused on the motor aspects of HD. Tetrabenazine is a dopamine-depleting agent that may be one of the more effective agents for reducing chorea, although it has a risk of potentially serious adverse effects. Some newer neuroleptic agents, such as olanzapine and aripiprazole, may have adequate efficacy with a more favorable adverse effect profile than older neuroleptic agents for treating chorea and psychosis. There are no current treatments to change the course of HD, but education and symptomatic therapies can be effective tools for clinicians to use with patients and families affected by HD.

    2006-01-01

    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

    Malaria is the tropical disease most commonly imported into the UK, with 1500-2000 cases reported each year, and 10-20 deaths. Approximately three-quarters of reported malaria cases in the UK are caused by Plasmodium falciparum, which is capable of invading a high proportion of red blood cells and rapidly leading to severe or life-threatening multi-organ disease. Most non-falciparum malaria cases are caused by Plasmodium vivax; a few cases are caused by the other two species of Plasmodium: Plasmodium ovale or Plasmodium malariae. Mixed infections with more than 1 species of parasite can occur; they commonly involve P. falciparum with the attendant risks of severe malaria. Management of malaria depends on awareness of the diagnosis and on performing the correct diagnostic tests: the diagnosis cannot be excluded until 3 blood specimens have been examined by an experienced microscopist. There are no typical clinical features of malaria, even fever is not invariably present. The optimum diagnostic procedure is examination of thick and thin blood films by an expert to detect and speciate the malarial parasites; P. falciparum malaria can be diagnosed almost as accurately using rapid diagnostic tests (RDTs) which detect plasmodial antigens or enzymes, although RDTs for other Plasmodium species are not as reliable. The treatment of choice for non-falciparum malaria is a 3-day course of oral chloroquine, to which only a limited proportion of P. vivax strains have gained resistance. Dormant parasites (hypnozoites) persist in the liver after treatment of P. vivax or P. ovale infection: the only currently effective drug for eradication of hypnozoites is primaquine. This must be avoided or given with caution under expert supervision in patients with glucose-6-phosphate dehydrogenase deficiency (G6PD), in whom it may cause severe haemolysis. Uncomplicated P. falciparum malaria can be treated orally with quinine, atovaquone plus proguanil (Malarone) or co-artemether (Riamet

    Pharmacotherapy with levodopa for Parkinson's disease provides symptomatic benefit, but fluctuations in (or loss of) response may eventually occur. Dopamine agonists are also helpful and, when taken with low doses of levodopa, often provide sustained benefit with fewer side effects; novel agonists and new methods for their administration are therefore under study. Other therapeutic strategies are being explored, including the use of type B monoamine oxidase inhibitors to reduce the metabolic breakdown of dopamine, catechol-O-methyltransferase inhibitors to retard the breakdown of levodopa, norepinephrine precursors to compensate for deficiency of this neurotransmitter, glutamate antagonists to counteract the effects of the subthalamic nucleus, and various neurotrophic factors to influence dopaminergic nigrostriatal cells. Surgical procedures involving pallidotomy are sometimes helpful. Those involving cerebral transplantation of adrenal medullary or fetal mesencephalic tissue have yielded mixed results; benefits may relate to the presence of growth factors in the transplanted tissue. The transplantation of genetically engineered cell lines will probably become the optimal transplantation procedure. The cause of Parkinson's disease may relate to oxidant stress and the generation of free radicals. It is not clear whether treatment with selegiline hydrochloride (a type B monoamine oxidase inhibitor) delays the progression of Parkinson's disease, because the drug also exerts a mild symptomatic effect. Daily treatment with vitamin E (a scavenger of free radicals) does not influence disease progression, perhaps because of limited penetration into the brain. Images PMID:7975571

    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.

    OBJECTIVE To review the evidence regarding treatment of herpes zoster (HZ) in the short-term, focusing on the prevention of postherpetic neuralgia (PHN). QUALITY OF EVIDENCE The evidence relating to treatment of HZ is derived mainly from randomized controlled trials (level I evidence). MAIN MESSAGE Antiviral drugs might have some effect on the severity of acute pain and on the duration of skin lesions. Corticosteroids also alleviate acute pain. Oral antiviral medication reduces the risk of eye complications in patients with ophthalmic HZ. There is no convincing evidence that antiviral medication reduces the risk of PHN. Some studies, however, have shown that famciclovir and valacyclovir shorten the duration of PHN. The effectiveness of amitriptyline or cutaneous and percutaneous interventions in preventing PHN has not been proven. CONCLUSION Oral antiviral drugs should be prescribed to elderly HZ patients with high risk of PHN. Moreover, these drugs should be prescribed to all patients at the first signs of ophthalmic HZ, irrespective of age or severity of symptoms. PMID:18337531

    A range of treatment options are available in rosacea, which include several topical (mainly metronidazole, azelaic acid, other antibiotics, sulfur, retinoids) and oral drugs (mainly tetracyclines, metronidazole, macrolides). In some cases, the first choice is a systemic therapy because patients may have sensitive skin and topical medications can be irritant. Isotretinoin can be used in resistant cases of rosacea. Unfortunately, the majority of studies on rosacea treatments are at high or unclear risk of bias. A recent Cochrane review found that only topical metronidazole, azelaic acid, and oral doxycycline (40 mg) had some evidence to support their effectiveness in moderate to severe rosacea and concluded that further well-designed, adequately-powered randomised controlled trials are required. In our practice, we evaluate our patients for the presence of two possible triggers, Helicobacter pylori infection and small intestinal bacterial overgrowth. When they are present we use adapted antibiotic protocols. If not, we use oral metronidazole or oral tetracycline to treat papulopustolar rosacea. We also look for Demodex folliculorum infestation. When Demodex concentration is higher than 5/cm(2) we use topical crotamiton 10% or metronidazole.

    Treatment of refractory ulcerative colitis (UC) is a common clinical challenge. In either acute or chronic refractory UC, the disease may continue to remain active, even though the patient is on appropriate therapy. It is important to reassess and characterize the patient's disease before adding new medications to the current medical regimen. After determining the current extent and severity of the UC—ruling out other causes of bloody diarrhea and determining what complications are present—new treatment approaches can then be started. It is critical to first optimize oral 5-aminosalicylic acid (5-ASA) therapy combined with rectal 5-ASA or corticosteroid suppositories, plus corticosteroid or 5-ASA enemas or foam preparations. Oral or intravenous corticosteroids are appropriate to use if needed, but alternative approaches must be used for long-term maintenance. 6-Mercaptopurine (6-MP) or azathioprine can be very helpful for severe chronic refractory UC. In those patients who do not respond to 5-ASA medications, corticosteroids, and 6-MP or azathioprine, infliximab offers an important approach for induction and maintenance of remission for refractory chronic ulcerative colitis as well as for select cases of refractory acute UC. Cyclosporine use is an alternative medical approach for the refractory acute UC patient. Colectomy with ileal pouch-anal anastomosis remains a valuable option for the refractory chronic or acute UC patient, because it can provide both a “cure” for the disease, as well as eliminate ineffective medications with their associated side effects.

    Hirsutism is usually the result of an underlying adrenal, ovarian, or central endocrine abnormality mainly due to polycystic ovary syndrome but may also be idiopathic or drug induced. The aim of medical treatment of hirsutism is to rectify any causal hormonal balance, slow down or stop excessive hair growth, and improve the aesthetic appearance of hirsutism, thereby positively affecting the patient's quality of life. Today, for the majority of women, a monotherapy with oral contraceptives that have antiandrogenic activity is recommended as a first-line treatment for hirsutism. Combining an oral contraceptive pill with an antiandrogen is recommended if clinical improvement of hirsutism is insufficient after 6-9 months' monotherapy. In women who present with hirsutism, hyperandrogenism, and insulin resistance, insulin sensitizers are effective for the hirsutism as well as the hyperinsulinemia, hyperandrogenism, and infertility but there is no convincing evidence that they are effective for hirsutism alone. Topical eflornithine is a medical therapy that can be a useful adjuvant for hirsutism when used in conjunction with systemic medications or with laser/photoepilation.

    Objective Chronic cough remains a challenging condition, especially in cases where it persists despite comprehensive medical management. For these particular patients, there appears to be an emerging role for behavior modification therapy. We report a series of patients with refractory chronic cough to assess if there is any benefit of adding behavioral therapy to their treatment regimen. Study Design A case series with planned chart review of patients treated for chronic cough. Setting The review was performed with an outpatient electronic health record system at a tertiary care center. Subjects and Methods The charts of all patients treated for chronic cough by a single laryngologist over a 30-month period were analyzed. Patients' response to treatment and rate of cough improvement were assessed for those with refractory chronic cough who underwent behavior modification therapy. Results Thirty-eight patients with chronic cough were initially treated empirically for the most common causes of cough, of which 32% experienced improvement. Nineteen patients who did not significantly improve with medical management underwent behavior modification therapy with a speech-language pathologist. Of these patients, 84% experienced resolution or marked improvement of their symptoms. Conclusion Behavioral therapy may be underutilized in practice and could lead to improvement of otherwise recalcitrant cough.

    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.

    2015-01-01

    Objective Despite the undisputed effectiveness of agonist maintenance for opioid dependence, individuals can remain on waitlists for months, during which they are at significant risk for morbidity and mortality. To mitigate these risks, the Food and Drug Administration in 1993 approved interim treatment, involving daily medication + emergency counseling only, when only a waitlist is otherwise available. We review the published research in the 20 years since the approval of interim opioid treatment. Methods A literature search was conducted to identify all randomized trials evaluating the efficacy of interim treatment for opioid-dependent patients awaiting comprehensive treatment. Results Interim opioid treatment has been evaluated in four controlled trials to date. In three, interim treatment was compared to waitlist or placebo control conditions and produced greater outcomes on measures of illicit opioid use, retention, criminality and likelihood of entry into comprehensive treatment. In the fourth, interim treatment was compared to standard methadone maintenance and produced comparable outcomes in illicit opioid use, retention and criminal activity. Conclusions Interim treatment significantly reduces patient and societal risks when conventional treatment is unavailable. Further research is needed to examine the generality of these findings, further enhance outcomes, and identify the patient characteristics which predict treatment response. PMID:25937593

    Pheochromocytoma is a tumor derived from chromaffin tissue, which secretes catecholamines. Today, about 90 percent of patients with this tumor are cured by surgical procedures. In 8 to 15 percent of patients with this tumor there is unresectable, recurrent or metastatic disease, which causes significant morbidity and mortality. The natural history of metastatic disease includes long-term survivors; many, however, die early of disseminated disease. The most common site of metastatic lesions is the skeleton. Palliation for these lesions can often be achieved with the use of radiation therapy. Other sites are, in general, less responsive to radiation therapy. Chemotherapy has been used in combination with radiation therapy, but the results generally have been disappointing. Chemotherapy with doxorubicin hydrochloride and cyclophosphamide in combination with radiation therapy has provided good palliation for skeletal disease for about five months, when disease progression was again noted. Further information is needed concerning the optimal chemotherapeutic treatment of this unusual tumor. PMID:629048

    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.

  19. Wastewater treatment with microalgae

    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.

    Proper classification of patients into diffuse cutaneous and limited cutaneous subsets and the anticipation of complications are the keys to the management of subjects with systemic sclerosis (scleroderma). Patients with early diffuse disease and rapidly progressive skin thickening are at highest risk of developing serious disease of the internal organs (intestine, lung, heart, kidney) and should be considered for disease modifying treatment. The targets of the disease and sites of possible intervention are vascular endothelium (vasoprotective agents), mononuclear cell subsets (immunosuppressive agents), and fibroblasts (colchicine, D-penicillamine). A number of new agents with sound scientific rationale are currently undergoing therapeutic trials. Much can be done to improve the lifestyle of those with scleroderma. The most dramatic recent development is the ability to reverse kidney disease by the prompt use of angiotensin converting enzyme inhibitors and modern methods of renal dialysis and transplantation. Scleroderma is not a hopeless disease. PMID:1750801

    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

    Chronic obstructive pulmonary disease (COPD) is a major health problem worldwide. It is characterised by chronic inflammation in the lungs that leads to progressive chronic airflow obstruction. The main strategy for treating COPD is control of the chronic inflammation. However, current anti-inflammatory treatments fail to prevent disease progression. New long-acting bronchodilators and their combinations are currently under development. Research has been focused on identifying the key inflammatory regulators. CXCR2 antagonists inhibit neutrophilic inflammation; inhibitors of phosphodiesterase-4 (PDE4), p38 mitogen-activated protein kinase (p38), Janus kinases and IL-6 have also shown some promising effects. There is an emerging need for identification of key modulators of the oxidative stress-regulated corticosteroid function aiming the development of monotherapies which will resolve any side effects issues currently faced.

    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.

    This task involves testing of sorbent materials for removing cesium, strontium, and technetium from the saline solutions in DOE storage tank supernatant at Oak Ridge and other sites. Staff at Oak Ridge National Laboratory (ORNL) are recovering and treating the liquid (supernatant) portions of Melton Valley Storage Tank (MVST) waste in a hot cell to separate and remove the radionuclides. Batch tests will be used to evaluate and select the most promising materials for supernatant treatment to reduce the amount of waste for final disposal. Small column tests will be made on selected sorbents to verify the batch data and to obtain additional data for process design. Efforts will be made to obtain samples of tank supernatant from Hanford for comparison.

    2000-01-01

    The scientific basis of tension- type headache suffers from the lack of precise pathophysiological knowledge and the heterogenecity of this disorder. Treatment of acute tension-type headache episodes is more effective with an NSAIDs (ibuprofen 400-800mg, naproxen 550-825mg, ketoprofen 50-75mg) than with aspirin or paracetamol. Caffein containing preparations of NSAIDs are slightly superior, but should not be taken frequently to avoid headache chronification. For chronic tension-type headache, relaxation therapies with EMG biofeedback and tricyclics have about the same efficacy rate of 40-50p.100. Physical therapy and acupuncture are in general less effective. There is thus clearly a need for better strategies, e.g. combination of available therapies and novel approaches.

    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.

    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.

    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.

    Autism is a chronic and lifelong pervasive developmental disorder for which there is yet no effective cure, and medical management remains a major challenge for clinicians. In spite of the possible similarities with conditions that have an established pharmacotherapy, and despite improvements in some associated "problematic behaviors" following the use of available medications, effective medical treatment for the core symptoms involving language and social cognition remains elusive. The purpose of the present article is to review current biologic knowledge about autism in an attempt to correlate clinical trials with known mechanisms of disease. In addition, the need for controlled studies and for the creation of homogeneous subgroups of patients based on clinical and genetic characteristics is emphasized. The application of molecular genetic investigations and pharmacogenetics in the diagnostic work-up of autistic patients can lead to more effective individualized medical care.

    The treatment of postmenopausal osteoporosis relies on management of some risk factors for fracture, e.g., risk factors for falls, improvement of calcium and vitamin D intake, and on various medications. All elderly women with calcium and vitamin D deficiency should receive calcium and vitamin D supplements. Estrogen replacement therapy should not longer be used to prevent or treat postmenopausal osteoporosis, owing to its poor long-term risk/benefit ratio. Raloxifene, biphosphonates (alendronate, risedronate) are well tolerated compounds with proven anti-fracture efficacy. Teriparatide is a new bone forming agent to treat severe osteoporosis. Strontium ranelate is a new drug also reducing the risk of fractures that should be available soon.

    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

    Nine patients with primary hyperoxaluria have been followed regularly for 1 to 11 years, and their treatment and progress are discussed in relation to the known natural history of the disease. 6 of them probably have the usual form of primary hyperoxaluria associated with increased glycollic acid excretion, while 3 who are sibs have the recently described variant associated with L-glyceric aciduria and normal glycollic acid excretion. All 9 patients have been on regimens designed to increase the urinary solubility of calcium oxalate, with or without the simultaneous lowering of urinary calcium and raising of urinary phosphate excretions. 8 patients have been treated for 1½-7½ years (average duration 4 years) with oral magnesium hydroxide, and 2 patients have been treated with sodium phosphate. One of the latter was changed after 3½ years to magnesium hydroxide and the other has been on sodium phosphate combined with a low calcium diet and cellulose phosphate continuously for 5½ years. 2, not at first diagnosed as hyperoxalurics, were first given sodium bicarbonate for their presumably secondary renal tubular acidosis. The over-all progress of the whole group is felt to have been better than could be expected from the known natural history of primary hyperoxaluria. They average 4¼ years on treatment during 5 years of our observation and all remain clinically well after an average of 9½ years since the onset of their first symptoms. Results warrant the recommendation that, until reliable means are available to decrease oxalate over-production, affected patients should be treated continuously with magnesium hydroxide. A more final opinion must await many more years of follow-up. The failure of several attempts to lower urinary oxalate excretion in these patients is also reported.

    What if neurofeedback or other types of neurotechnological treatment, by itself or in combination with behavioral treatment, could achieve a successful "rewiring" of the psychopath's brain? Imagine that such treatments exist and that they provide a better long-term risk-minimizing strategy compared to imprisonment. Would it be ethical to offer such treatments as a condition of probation, parole, or (early) prison release? In this paper, I argue that it can be ethical to offer effective, non-invasive neurotechnological treatments to offenders as a condition of probation, parole, or (early) prison release provided that: (1) the status quo is in no way cruel, inhuman, degrading, or in some other way wrong, (2) the treatment option is in no way cruel, inhuman, degrading, or in some other way wrong, (3) the treatment is in the best interests of the offender, and (4) the offender gives his/her informed consent.

    With a continuing increase in the number of tattoos performed worldwide, the need to treat tattoo complications is growing. Earlier treatments of chronic inflammatory tattoo reactions were dominated by a medical approach, or with no active intervention. In this chapter, we will address modern surgical approaches applied to situations when medical treatment is inefficient and lasers are not applicable. Dermatome shaving is positioned as first-line treatment of allergic tattoo reactions and also indicated in a number of other tattoo reactions, supplemented with excision in selected cases. The methods allow fundamental treatment with removal of the culprit pigment from the dermis. The different instruments, surgical methods, and treatment schedules are reviewed, and a guide to surgeons is presented. Postoperative treatments and the long-term outcomes are described in detail. An algorithm on specialist treatment and follow-up of tattoo reactions, which can be practiced in other countries, is presented.

    Tobacco use is associated with 5 million deaths per year worldwide and is considered as one of the leading causes of premature death. Comprehensive tobacco control programs can significantly reduce the prevalence of tobacco use. An important component of a comprehensive program is the provision of treatment for tobacco addiction. Treatment involves targeting multiple aspects of addiction including the underlying neurobiology and behavioral processes. Furthermore, building an infrastructure in health systems that encourage and facilitate cessation and expanding the accessibility of treatments are necessary. While current pharmacological and behavioral treatments are effective in improving cessation success, the rate of relapse to smoking remains high, demonstrating the strong addictive nature of nicotine. The future of treatment resides in better patient matching to treatment, combination or novel medications, and conceptualizing nicotine addiction as a chronic disorder which may require long-term treatment.

    2012-01-01

    Long-acting injectable antipsychotics (LAIs) should offer better efficacy and tolerability, compared to oral antipsychotics due to improved adherence and more stable pharmacokinetics. However, data on LAIs has been mixed, with some studies finding that they are more effective and tolerable than oral antipsychotics, and others finding the contrary. One possibility for the disparate results may be that some studies administered different antipsychotics in the oral and injectable form. The present systematic review examined the efficacy and tolerability of LAIs versus their oral equivalents in randomized and naturalistic studies. In addition, it examined the impact of LAIs on special populations such as patients with first-episode psychosis, substance use disorders, and a history of violence or on involuntary outpatient commitment. Randomized studies suggest that not all LAIs are the same; for example, long-acting risperidone may be associated with equal or less side effects than oral risperidone, whereas fluphenazine decanoate and enanthate may be associated with equal or more side effects than oral fluphenazine. They also suggest that LAIs reduce risk of relapse versus oral antipsychotics in schizophrenia outpatients when combined with quality psychosocial interventions. For their part, naturalistic studies point to a larger magnitude of benefit for LAIs, relative to their oral equivalents particularly among first-episode patients. PMID:22966436

    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. PMID:23023162

    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.

    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

    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.

    2004-01-01

    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.

    Urosepsis is one of the most frequent sepsis entities. Mortality from urosepsis is nowadays mostly lower than from other entities. Sepsis syndrome is pathophysiologically characterized by a generalized infection and immune dysregulation. Exogenous microbiological and active or passive endogenous factors released from body cells initiate and accompany the immune dysregulation. Diagnosis and therapy of urosepsis need to be instigated as early as possible (within the first hour), in order to prevent cell and tissue damage in the early phase. For this reason a series of measures is started, aimed at achieving early control of the focus of infection, providing antibiotic treatment, and stabilizing respiratory and cardiovascular function in order to optimize tissue oxygenation. A significant clinical problem ensues due to increasing antibiotic resistance mainly of enterobacteria. The choice of antibiotic therefore is made on the basis of local antibiotic resistance statistics. Dosage is determined on an individual basis, as well as according to current pharmacokinetic/pharmacodynamic knowledge. The intensive care of the septic patient needs to be started as early as on patient admission and, where necessary, continued on the intensive care ward.

    2016-06-01

    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.

    Methane is a significant GHG, and substantial reservoirs are vulnerable to instability due to AGW. Excursions, from permafrost and clathrates especially, act a positive feedback to AGW. Existing concentrations of well-mixed atmospheric methane substantially exceed pre-industrial levels. Various geoengineering methods are herein proposed for containment of methane, and/or accelerated oxidation to CO2 (a gas with a lower GWP over all timescales). A basic qualitative analysis of each technique is undertaken, to direct further study. Consideration is also given to the potential capacity of each technique to treat the total likely excursions of methane expected as a result of AGW. Proposed techniques: Section 0 SRM (comparison option) Section 1 Pre-emptive treatment of methane reservoirs Soil heating (polytunnels, heat pumps); Soil aeration; Mining of clathrates; Burning of clathrates Section 2 Remediation of aquatic methane excursions Lake sealing; Mixing of aquatic strata; Bubble capture; Lake aeration; Biological oxidation in aquatic environments Section 3 Remediation of concentrated atmospheric methane Regenerative thermal oxidation; Electrical ignition; Thermal ignition; Using incendiary munitions Section 4 Remediation of diffuse atmospheric methane Thermal oxidation by concentrated solar power; Compression ignition; Chemical degradation Assessment criteria: Infrastructure/implementation cost; Energy cost; Expected efficacy; Complexity/development path; Environmental impacts; Potential for CCS

    Experimental procedures and current state-of-the-art are presented for laser surface treating methods such as alloying, cladding, grain refining, and transformation hardening using a cw CO2 laser. Microstructural and x-ray analyses of the treated surfaces indicate that a laser beam can locally enhance surface properties. Laser alloying offers the possibility to selectively modify a low cost workpiece surface so that it has the desired high quality surface properties characteristic of high performance alloys. Laser cladding offers feasibility to apply high melting cladding alloys on low melting workpieces, to reduce the amount of dilution of cladding alloy with the workpieces, and the potential to apply dense ceramic claddings to metallic workpieces. Laser grain refining offers potential to either minimize or eliminate surface defects such as inclusions, intermetallic compounds, and pores, and to provide a refined grain structure. Laser transformation hardening provides the treated workpieces with a hard martensitic surface that has compressive stresses for enhanced fatigue life; in addition, reduction in wear rate of treated surfaces is achieved. This experimental study indicates that the use of lasers for surface treatment has several limitations. Further studies will provide better understanding for maximum utilization of laser surface treating processes.

    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

    The prevalence of idiopathic nephrolithiasis is increasing in rich countries. Dietary manipulation could contribute to the prevention of both its first appearance and the recurrence of the disease. The target of dietary treatment is to decrease the “urinary lithogenic risk factors” such as low urine volume, hypercalciuria, hyperoxaluria, hyperuricosuria, hyperphosphaturia, hypocitraturia, hypomagnesuria and excessively alkaline or acid urinary pH. Due to the lack of randomized controlled trials focused on this problem, there is not ample evidence to confidently recommend dietary changes. Despite this, numerous recent and past experiences support modification of diet as having a primary role in the prevention of nephrolithiasis. In particular, it is recommended to limit animal protein and salt intake, to consume milk and derivatives in amounts corresponding to calcium intake of about 1200 mg/day and to assume fiber (40 g/day), vegetables and fruit daily avoiding foods with high oxalate content. Furthermore, vitamin C intake not exceeding 1500 mg/day plays a protective role as well as avoiding vitamin B6 deficiency and abstaining, if possible, from vitamin D supplements. Lastly, it is recommended to drink enough water to bring the urinary volume up to at least 2 L/day and, as much as possible, to use fresh or frozen products rather than prepacked or precooked foods which are often too rich in sodium chloride.

  8. Treatment of mandibular prognathism.

    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.

    The treatment of Acanthamoeba keratitis has now been possible since the first successful therapy developed in the mid 1980s with a combination of propamidine 0.1% (Brolene) and neomycin 1%. However, only half the patients responded to this regimen as the cysts were often resistant to neomycin and relatively insensitive to propamidine. This led to research for better therapy, culminating in the mid 1990s with research in Glasgow demonstrating much increased effectiveness with use of the biguanide chlorhexidine 0.02% and in London and Bristol for similar effectiveness with the polymeric polyhexamethylene biguanide (PHMB) 0.02%. Both biguanides were combined with propamidine for enhanced effectiveness but were also shown to be effective as monotherapy. While this therapy inactivates the trophozoites and cysts in Acanthamoeba keratitis in the majority of patients (approximately 90%), there have been notable failures particularly when presentation is late with deep stromal infection. Additional highly acanthamoebicidal drugs are needed that can penetrate the stroma for synergistic action. This role may be taken up by certain antineoplastic drugs, such as alkylphosphocholine-1 (Miltefosine), that also have antiprotozoal activity.

    In a controlled field trial, 178 dairy cows with chronic endometritis and at least 21 days in lactation were randomly assigned to four different treatment groups: prostaglandin F2alpha intramuscularly (PG, 5 mg dinoprost (5 ml Dinolytic), n = 51), intrauterine antibiotics (AB; 400 mg ampicillin + 800 oxacillin (20 ml Totocillin), n = 49), intrauterine antiseptics (AS; 100 ml 4% Lotagen, n = 50); control (C, no initial treatment, n = 28). Before treatment, uterine swabs for bacteriologic examination and blood samples for determination of serum progesterone concentrations were collected. Two weeks following the first treatment, cows were reexamined. In case no clinical cure was diagnosed, treatment was repeated and control cows were treated for the first time with one of the three treatments mentioned above. The four treatment groups did not differ with respect to the clinical cure or reproductive performance. Therefore, factors that might have an influence on clinical cure and fertility were evaluated. With increasing duration of lactation, the clinical cure after a single treatment increased significantly over all treatment groups from 59.5% (treatment before day 42 postpartum) to 79.6% (treatment following day 42 postpartum) (P < 0.05). Within the PG group, a statistically significantly higher cure rate after a single treatment and first service conception rate and a lower pregnancy index were obtained when the treatment was performed following day 42 postpartum (P < 0.05). This was not the case in the other treatment groups. A retarded involution of the uterus based on the size had a negative effect on clinical cure over all groups (first treatment clinical cure: 68.2% (small uteri) vs 44.4% (large uteri); P < 0.05). Within groups, this effect was also detected, but only as a trend (P > 0.05). Isolation of Arcanobacterium (A.) pyogenes negatively influenced first treatment clinical cure over all treatment groups (79.0% vs 31.5%) and within treatment groups (P < 0

  11. Treatment of mastitis during lactation

    PubMed Central

    2009-01-01

    Treatment of mastitis should be based on bacteriological diagnosis and take national and international guidelines on prudent use of antimicrobials into account. In acute mastitis, where bacteriological diagnosis is not available, treatment should be initiated based on herd data and personal experience. Rapid bacteriological diagnosis would facilitate the proper selection of the antimicrobial. Treating subclinical mastitis with antimicrobials during lactation is seldom economical, because of high treatment costs and generally poor efficacy. All mastitis treatment should be evidence-based, i.e., the efficacy of each product and treatment length should be demonstrated by scientific studies. Use of on-farm written protocols for mastitis treatment promotes a judicious use of antimicrobials and reduces the use of antimicrobials. PMID:22081939

    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 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.

    The author believes that psychocutaneous medicine has indeed come of age and is being incorporated into mainstream medical practice. Patients presenting to dermatologists today are more sophisticated and are frequently dissatisfied with traditional medical therapies. They actively seek alternative approaches and adjuncts to standard treatments. In contrast to many other "alternative" (or) "holistic" treatments offered through non-medical venues, dermatologists can assure their patients that controlled studies support the efficacy of psychocutaneous techniques in improving many dermatologic conditions. Psoriasis, rosacea, herpes simplex, body dysmorphic disorder, acne, eczema, urticaria, neurotic excoriations, excoriated acne, trichotillomania, dysesthetic syndromes, and delusions parasitosis are included in this incomplete list. The author believes it is helpful for both the patient and therapist to define concrete and realistic goals for psychocutaneous intervention. Concrete observable or measurable goals can help the patient and clinician gauge therapeutic progress and success. Specifically, goals can include reduction in pruritus (rating severity from 1-10), decreased scratching activity, decreased plaque extent or thickness, decreased number of urticarial plaques, decreased flushing, decreased anxiety, decreased anger, decreased social embarrassment, decreased social withdrawal, and improved sleep. More global goals can include an improved sense of well-being, increased sense of control, and enhanced acceptance of some of the inevitable aspects of a given skin disease. Cure should never be a goal, because most disorders amenable to psychocutaneous techniques are chronic in nature; thus, cure as an endpoint would only lead to disappointment. The author encourages dermatologists to align themselves with what he euphemistically calls "a skin-emotion specialist." The skin-emotion specialist may be a psychiatrist, psychologist, social worker, biofeedback therapist

    Primary phenylalanine hydroxylase deficiency, also known as phenylketonuria, results in accumulation of phenylalanine in the blood. Early identification and treatment prevents the majority of clinical sequelae to the disease, but psychological and neurodevelopmental problems can occur in some patients. This article reviews the symptoms, diagnosis, classification and strategies of treatment and management of phenylketonuria. Finally we review new pharmacological and non-pharmaco-logical means of treatment.

    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.

    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

  19. Sewage sludge treatment system

    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.

  20. Hypophosphatasia - pathophysiology and treatment

    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
