    The aim of this phase II study was to evaluate the pharmacokinetics, pharmacodynamics, efficacy, and safety of a 6- month depot formulation of a luteinizing hormone-releasing hormone (LH-RH) agonist, TAP-144-SR (6M), in Japanese treatment-naÏve patients with prostatic cancer. Each subject received a single subcutaneous or intramuscular injection of TAP- 144-SR (6M) and was monitored for 24 weeks. The primary endpoint was the change in serum testosterone levels. The serum testosterone level in six subjects who received 22.5 mg of TAP-144 (SR) subcutaneously decreased below the castrate level after 4 weeks and remained suppressed during the 24 weeks of follow-up. With regard to safety, TAP-144-SR (6M)was not associated with any additional concerns compared to those reported for the approved 1-month and 3-month depot formulations of TAP-144-SR. In addition, 30 mg of TAP-144-SR (6M) was administered subcutaneously to six subjects, and, on the basis of the results, the optimal clinical dosage of TAP-144-SR (6M) in Japan was considered to be 22.5 mg. Outcomes with 22.5mg TAP-144-SR (6M) administered intramuscularly were similar to those with TAP-144-SR (6M) administered subcutaneously.

    Full Text Available Subcutaneous emphysema of the scalp is a process often attributed to secondary factors such as trauma, infection, or a myriad of iatrogenic etiologies. Here, we are presenting a case report of an adult patient with spontaneous subcutaneous emphysema of the scalp following a hair coloring/treatment. We performed an extensive review of literature on this topic, however, could not find a single case with similar presentation of subcutaneous emphysema. This case demonstrates an unreported etiology for this diagnosis and is thus being reported for its uniqueness and to raise clinical awareness.

    To study the efficacy of subcutaneous steroid injection in the treatment of chalazion. Prospective consecutive case series. University teaching hospital, Hong Kong. Patients with chalazion presenting to the out-patient clinic of the Department of Ophthalmology at the Prince of Wales Hospital from January to June 1998. Size of the chalazion after steroid injection treatment. Forty-eight consecutive patients with chalazion were treated with injection of triamcinolone into the subcutaneous tissue around the lesion. In 43 (89.6%) patients, the lesion subsided completely. Twenty-six (54.2%) patients had lesions that subsided with one injection. The size and duration of the chalazion at presentation did not significantly affect the outcome of the treatment. Two patients developed depigmentation of the skin at the site of injection. No other major complications were encountered. Subcutaneous injection of the steroid triamcinolone acetonide appears to be a simple and effective treatment for chalazion. Further comparative clinical trials are indicated.

    The treatment of Tarlov cysts is challenging and difficult. The objective of our study was to describe the security and efficacy of the subcutaneous infusion port for drainage of symptomatic Tarlov cysts. The authors executed a retrospective review of data from 5 symptomatic Tarlov cysts patients who were treated using a subcutaneous infusion port from June 2014 to July 2017. Numerical Rating Scale scores and the Japanese Orthopedic Association scores of back pain were analyzed. Complications and adverse effects on postoperative days 1, 7, 14, and 28 were also analyzed. The mean follow-up was 12.6 months. Five adults (3 females and 2 males) who had been symptomatic received a subcutaneous infusion port. After treatment, all patients experienced pain relief and pain alleviation lasted from 1 day to 3 years without complications and adverse effects. A subcutaneous infusion port is a useful treatment option for symptomatic Tarlov cysts. When the patients' symptoms returned and the cysts repressurized, we quickly and simply drained the cysts by using the infusion port. Copyright © 2018 Elsevier Inc. All rights reserved.

    Cervicofacial subcutaneous emphysema is a rare complication of dental procedures. Although most cases of emphysema occur incidentally with the use of a high-speed air turbine handpiece, there have been some reports over the past decade of cases caused by dental laser treatment. Emphysema as a complication caused by the air cooling spray of a dental laser is not well known, even though dental lasers utilize compressed air just as air turbines and syringes do. In this study, we comprehensively reviewed cases of emphysema attributed to dental laser treatment that appeared in the literature between January 2001 and September 2012, and we included three such cases referred to us. Among 13 cases identified in total, nine had cervicofacial subcutaneous and mediastinal emphysema. Compared with past reviews, the incidence of mediastinal emphysema caused by dental laser treatment was higher than emphysema caused by dental procedure without dental laser use. Eight patients underwent CO2 laser treatment and two underwent Er:YAG laser treatment. Nine patients had emphysema following laser irradiation for soft tissue incision. Dentists and oral surgeons should be cognizant of the potential risk for iatrogenic emphysema caused by the air cooling spray during dental laser treatment and ensure proper usage of lasers. © 2013 Australian Dental Association.

    The therapeutic efficacy of high-dose intravenous immunoglobulin in systemic lupus erythematosus (SLE) patients is well established. However, side effects might limit its use and lead to the consideration of therapeutic alternatives, such as the subcutaneous formulation of immunoglobulin, which has been used in some patients with other autoimmune diseases. We report a case of SLE refractory to classical therapies. High-dose intravenous immunoglobulin was effective, but gave rise to significant side effects. The patient was successfully treated with subcutaneous human immunoglobulin, achieving and maintaining clinical and laboratory remission. A lower immunoglobulin dose was needed and no side effects were observed, compared to the intravenous administration. Subcutaneous immunoglobulin could be a better-tolerated and cost-saving therapeutic option for select SLE patients. © The Author(s) 2016.

    Full Text Available Johanna C Moore, James R MinerDepartment of Emergency Medicine, Hennepin County Medical Center, Minneapolis, MN, USAAbstract: Subcutaneous sumatriptan is an effective treatment for pain from acute migraine headache, and can be used in patients with known migraine syndrome and in patients with primary headaches when secondary causes have been excluded. In limited comparative trials, subcutaneous sumatriptan performed in a manner comparable with oral eletriptan and intravenous metoclopramide, was superior to intravenous aspirin and intramuscular trimethobenzamide-diphenhydramine, and was inferior to intravenous prochlorperazine for pain relief. The most common side effects seen with subcutaneous sumatriptan are injection site reactions and triptan sensations. As with all triptans, there is a risk of rare cardiovascular events with subcutaneous sumatriptan and its use should be limited to those without known cerebrovascular disease and limited in those with known cardiovascular risk factors and unknown disease status. In studies of patient preference and tolerability, the subcutaneous formulation has a faster time of onset and high rate of efficacy when compared with the oral formulation, but the oral formulation appears to be better tolerated. It is important to consider the needs of the patient, their past medical history, and what aspects of migraine treatment are most important to the patient when considering treatment of acute migraine or primary headache. Subcutaneous sumatriptan is a good first-line agent for the treatment of pain from acute migraine headaches and primary headaches.Keywords: sumatriptan, subcutaneous, migraine headache, primary headache

    Transdermal fentanyl is effective for the treatment of moderate to severe cancer-related pain but is unsuitable for fast titration. In this setting, continuous subcutaneous fentanyl may be used. As data on the pharmacokinetics of continuous subcutaneous fentanyl are lacking, we studied the pharmacokinetics of subcutaneous and transdermal fentanyl. Furthermore, we evaluated rotations from the subcutaneous to the transdermal route. Fifty-two patients treated with subcutaneous and/or transdermal fentanyl for moderate to severe cancer-related pain participated. A population pharmacokinetic model was developed and evaluated using non-linear mixed-effects modelling. For rotations from subcutaneous to transdermal fentanyl, a 1:1 dose conversion ratio was used while the subcutaneous infusion was continued for 12 h (with a 50 % tapering after 6 h). A 6-h scheme with 50 % tapering after 3 h was simulated using the final model. A one-compartment model with first-order elimination and separate first-order absorption processes for each route adequately described the data. The estimated apparent clearance of fentanyl was 49.6 L/h; the absorption rate constant for subcutaneous and transdermal fentanyl was 0.0358 and 0.0135 h(-1), respectively. Moderate to large inter-individual and inter-occasion variability was found. Around rotation from subcutaneous to transdermal fentanyl, measured and simulated plasma fentanyl concentrations rose and increasing side effects were observed. We describe the pharmacokinetics of subcutaneous and transdermal fentanyl in one patient cohort and report several findings that are relevant for clinical practice. Further research is warranted to study the optimal scheme for rotations from the subcutaneous to the transdermal route.

    It has always been controversial whether a single allergen performs better than multiple allergens in polysensitized patients during the allergen-specific immunotherapy. This study aimed to examine the clinical efficacy of single-allergen sublingual immunotherapy (SLIT) versus multi-allergen subcutaneous immunotherapy (SCIT) and to discover the change of the biomarker IL-4 after 1-year immunotherapy in polysensitized children aged 6-13 years with allergic rhinitis (AR) induced by house dust mites (HDMs). The AR polysensitized children (n=78) were randomly divided into two groups: SLIT group and SCIT group. Patients in the SLIT group sublingually received a single HDM extract and those in the SCIT group were subcutaneously given multiple-allergen extracts (HDM in combination with other clinically relevant allergen extracts). Before and 1 year after the allergen-specific immunotherapy (ASIT), the total nasal symptom scores (TNSS), total medication scores (TMS) and IL-4 levels in peripheral blood mononuclear cells (PBMCs) were compared respectively between the two groups. The results showed that the TNSS were greatly improved, and the TMS and IL-4 levels were significantly decreased after 1-year ASIT in both groups (SLIT group: P0.05; for TMS: P>0.05; for IL-4 levels: P>0.05). It was concluded that the clinical efficacy of single-allergen SLIT is comparable with that of multi-allergen SCIT in 6-13-year-old children with HDM-induced AR.

    Full Text Available Objective: To compare the cost of treating rheumatoid arthritis patients that have failed an initial treatment with methotrexate, with subcutaneous aba - tacept versus other first-line biologic disease-modifying antirheumatic drugs. Method: Subcutaneous abatacept was considered comparable to intravenous abatacept, adalimumab, certolizumab pegol, etanercept, golimumab, infliximab and tocilizumab, based on indirect comparison using mixed treatment analysis. A cost-minimization analysis was therefore considered appropriate. The Spanish Health System perspective and a 3 year time horizon were selected. Pharmaceutical and administration costs (, 2013 of all available first-line biological disease-modifying antirheumatic drugs were considered. Administration costs were obtained from a local costs database. Patients were considered to have a weight of 70 kg. A 3% annual discount rate was applied. Deterministic and probabilistic sensitivity analyses were performed. Results: Subcutaneous abatacept proved in the base case to be less costly than all other biologic antirrheumatic drugs (ranging from -831.42 to -9,741.69 versus infliximab and tocilizumab, respectively. Subcutaneous abatacept was associated with a cost of 10,760.41 per patient during the first year of treatment and 10,261.29 in subsequent years. The total 3-year cost of subcutaneous abatacept was 29,953.89 per patient. Sensitivity analyses proved the model to be robust. Subcutaneous abatacept remained cost-saving in 100% of probabilistic sensitivity analysis simulations versus adalimumab, certolizumab, etanercept and golimumab, in more than 99.6% versus intravenous abatacept and tocilizumab and in 62.3% versus infliximab. Conclusions: Treatment with subcutaneous abatacept is cost-saving versus intravenous abatacept, adalimumab, certolizumab, etanercept, golimumab, infliximab and tocilizumab in the management of rheumatoid arthritis patients initiating

  15. Regulation of local subcutaneous blood flow in patients with psoriasis and effects of antipsoriatic treatment on subcutaneous blood flow

    Local regulation of the doubled subcutaneous blood flow (SBF) rates in psoriatic lesional skin was studied in 8 patients using a traumatic epicutaneous 133 Xe labeling washout technique. Venous stasis of 40 mm Hg induced a significant reduction in the SBF (-34%, p less than 0.01), i.e., a normal vasoconstrictor response. Limb elevation of 40 cm above heart level induced no statistical changes in the SBF (p = 0.50), i.e., a normal local autoregulation response. This indicates normal, local regulation mechanisms of SBF in psoriasis. In another 8 patients, the effect on SBF of a 4-week antipsoriatic treatment with tar was studied in lesional and symmetrically nonlesional skin areas. One patient was clear of psoriasis on day 22, and was followed only to that time. The mean pretreatment SBF in lesional skin areas was 3.87 +/- SD 0.78 ml X (100 g X min)-1, which was not statistically different from measurements on days 3, 7, 14, and 21 after treatment had started. Between day 21 and day 28, the SBF decreased significantly to 3.38 +/- SD 0.78 ml X (100 g X min)-1, p less than 0.05. The difference between the pretreatment SBF and SBF at the end of treatment was statistically significant, p less than 0.05. The changes in SBF in symmetrically nonlesional skin areas were statistically nonsignificant during the period of treatment. Pretreatment SBF was 2.60 +/- SD 1.08 (N = 8), and on day 28 was 1.91 +/- SD 0.74 ml X (100 g X min)-1 (N = 7). However, the tendency of a decreasing SBF at the end of treatment was a clear trend, since SBF in 6 of 7 patients decreased during the third week and in the patient who was discharged on day 22, a decrease in the SBF was observed on days 14 and 21

    The goal of this work is to quantify impact of in vivo photochemical treatment using indocyanine green (ICG) or encapsulated ICG and NIR laser irradiation through skin of rat with obesity by the follow up tissue sampling and histochemistry. After 1 hour elapsed since 1-min light exposure samples of rat skin with subcutaneous tissue of thickness of 1.5-2.5 mm were taken by surgery from rats within marked 4-zones of the skin site. For hematoxylin-eosin histological examination of excised tissue samples, fixation was carried out by 10%-formaldehyde solution. For ICG and encapsulated ICG subcutaneous injection and subsequent 1-min diode laser irradiation with power density of 8 W/cm2, different necrotic regions with lipolysis of subcutaneous fat were observed. The obtained data can be used for safe layer-by-layer laser treatment of obesity and cellulite.

    Deep digital septic conditions represent some of the most refractory causes of severe lameness in cattle. The objective of this study was to determine the distribution of tulathromycin, gamithromycin and florfenicol into the synovial fluid of the metatarsophalangeal (MTP) joint of cattle after single subcutaneous administration of drug to evaluate the potential usefulness of these single-dose, long-acting antimicrobials for treating bacterial infections of the joints in cattle. Twelve cross-bred beef cows were randomly assigned to one of the drugs. Following subcutaneous administration, arthrocentesis of the left metatarsophalangeal joint was performed at various time points up to 240 hours post-injection, and samples were analyzed for drug concentration. In synovial fluid, florfenicol pharmacokinetic parameters estimates were: mean Tmax 7 +/- 2 hours, mean t½ 64.9 +/- 20.1 hours and mean AUC0-inf 154.0 +/- 26.2 ug*h/mL. Gamithromycin synovial fluid pharmacokinetic parameters estimates were: mean Tmax 8 hours, mean t½ 77.9 +/- 30.0 hours, and AUC0-inf 6.5 +/- 2.9 ug*h/mL. Tulathromycin pharmacokinetic parameters estimates in synovial fluid were: Tmax 19 +/- 10 hours, t½ 109 +/- 53.9 hours, and AUC0-inf 57.6 +/- 28.2 ug h/mL. In conclusion, synovial fluid concentrations of all three antimicrobials were higher for a longer duration than that of previously reported plasma values. Although clinical data are needed to confirm microbiological efficacy, florfenicol achieved a synovial fluid concentration greater than the MIC90 for F. necrophorum for at least 6 days.

    Diabetic ketoacidosis (DKA) treatment protocols vary, however low-dose intravenous administration of regular insulin is the standard care for replacing insulin in most centers. Few studies, the majority in adults, demonstrated subcutaneous injection of rapid-acting insulin every 1-2 hours to be a valid alternative. To evaluate the efficacy and safety of subcutaneous regular insulin administered every 4 hours in pediatric DKA in a clinical setting. A retrospective chart review was conducted. Charts of all children treated with subcutaneous regular insulin for DKA and pH ≥ 7.0, between 2007 and 2010, were reviewed. Seventy-six DKA episodes in 52 patients were included. Data regarding clinical characteristics, response to treatment, and the occurrence of complications were analyzed. DKA episodes in patients with new-onset diabetes and in those with established diabetes were compared. Mean age was 11.6 ± 4.0 yr. Eighteen episodes occurred in children with new-onset diabetes. In all episodes, our protocol resulted in recovery from DKA. Median time to DKA resolution (pH > 7.30, HCO3 > 15) was 10.3 (5.5, 14.2) h. The median total insulin dose was 0.05 (0.04, 0.06) (unit/kg/h). During DKA treatment, hypoglycemia occurred in one episode and hypokalemia, mostly mild, was documented in 14. No cardiac arrhythmias, incidents of cerebral edema, or mortality occurred. Subcutaneous regular insulin administered every 4 hours is an effective and safe alternative for the insulin treatment of DKA with pH > 7.0 in children. Such treatment has the potential to simplify insulin administration when compared to either intravenous regular insulin or q1-2 hour subcutaneous rapid insulin and reduce both patient inconvenience and admission costs. © 2016 John Wiley & Sons A/S.

In our experiments, we used 3 to 3.5 months-old non-pedigree (nonlinear white mice (mass: 18-30 gram. After mice selection for the experiments, animals were placed in vivarium, in quarantine regime for 10 to 4 days. Individual protocols were drawn for each animal. Similar feeding and handling regimes were created for all animals. Transplantable malignant cancer strain, Erlich adenocarcinoma, was used. Results: Experiments on animals were successful. There are positive conclusions of pathological-anatomy laboratory “PathGeo”: Form # IV -200- 6A, for the examination # 3119-12 and # 15/02 and macro-morphological and micro-morphological description of the study # 15272-13. On the basis of the results of morphological study, it was proved that liver and lungs (the main target bodies were intact, and secondary cancer injuries were not fixed. After three sessions of hyperthermia treatment, the decrease in sizes of cancer formations and necrosis of diseased sections were visualized, while massive necrosis was observed after seven sessions. In all cases, necrosis and ulceration of diseased places were observed, which refers to transition of cancer into phase of healing. After eight-ten sessions, necrosis of cancer and ulceration were observed, which refers to irreversibility of the process and efficiency of the applied method of hyperthermia. Conclusion: Anticancer effect of hyperthermia conditioned by temperature fields was proved, which was expressed in inhibition of cancer growth, resorption and increase of

    Intravenous immunoglobulin replacement therapy represents the standard treatment for hypogammaglobulinemia secondary to B-cell lymphoproliferative disorders. Subcutaneous immunoglobulin infusion is an effective, safe and well-tolerated treatment approach in primary immunodeficiencies but no extensive data are available on their use in secondary hypogammaglobulinemia, a frequent phenomenon occurring after treatment with anti-CD20 monoclonal antibodies in lymphoproliferative disorders. In this retrospective study we evaluated efficacy (serum IgG trough levels, incidence of infections per year, need for antibiotics) and safety (number of adverse events) of intravenous (300 mg/kg/4 weeks) versus subcutaneous (75 mg/kg/week) immunoglobulin replacement therapy in 61 patients. In addition, the impact of the infusion methods on quality of life was compared. All patients were treated with subcutaneous immunoglobulin, and 33 out of them had been previously treated with intravenous immunoglobulin. Both treatments appeared to be effective in replacing Ig production deficiency and in reducing the incidence of infectious events and the need for antibiotics. Subcutaneous immunoglobulin obtained a superior benefit when compared to intravenous immunoglobulin achieving higher IgG trough levels, lower incidence of overall infection and need for antibiotics. The incidence of serious bacterial infections was similar with both infusion ways. As expected, a lower number of adverse events was registered with subcutaneous immunoglobulin, compared to intravenous immunoglobulin, with no serious adverse events. Finally, we observed an improvement in health-related quality of life parameters after the switch to subcutaneous immunoglobulin. Our results suggest that subcutaneous immunoglobulin is safe and effective in patients with hypogammaglobulinemia associated to lymphoproliferative disorders. Copyright© Ferrata Storti Foundation.

    Information regarding analgesics in pinnipeds is limited. This study aimed to establish the pharmacokinetic parameters of a single subcutaneous dose of sustained release buprenorphine (Buprenorphine SR) in juvenile northern elephant seals (Mirounga angustirostris) with regard to its potential to provide long-lasting analgesia that requires infrequent dosing. Seals (n=26) were administered a single dose of sustained release buprenorphine at 0.12 mg/kg s.c. Blood samples were collected from the extradural intervertebral vein at 0 hr and at three or four of the following time points: 0.5, 1, 2, 6, 12, 24, 36, 48, 60, 96, 120, and 144 hr. Seals were examined daily for systemic and local adverse reactions. Plasma was analyzed by liquid chromatography tandem-mass spectrometry for buprenorphine and norbuprenorphine concentrations. A noncompartmental analysis for pharmacokinetic parameters was calculated using standard methods and equations. An average maximum concentration of 1.21 ng/ml (0.3-2.9 ng/ml) was detected 12 hr postadministration. Concentrations were quantifiable up to 144 hr postadministration but were below those expected to provide analgesia in some other species. No systemic adverse effects were noted in healthy seals receiving sustained release buprenorphine. Cellulitis or abscesses at the injection site were observed in 6/26 (23%) seals between 24 and 168 hr postadministration. Adverse local effects suggest that this drug should be used with caution in northern elephant seals.

    To compare the efficacy of subcutaneous extralesional triamcinolone acetonide injection versus conservative treatment for chalazion. Randomised controlled trial. Eye clinics of two regional hospitals in Hong Kong. Patients over 18 years old presenting with primary chalazion were randomised into two groups. In group 1, 12 patients were treated with lid hygiene, warm compresses, and chloramphenicol 1% ointment 4 times a day. In group 2, 16 patients were treated with 0.3 mL triamcinolone acetonide (10 mg/mL) injection to the subcutaneous tissue extralesionally via the percutaneous route. Exclusion criteria were: acutely infected chalazion with preseptal cellulitis, recurrent chalazion, small chalazion (chalazion. Size of chalazion, recurrence of chalazion, intra-ocular pressure, and complications from treatment, including skin pigmentary change or atrophy and pyogenic granuloma. There was a clinically and statistically significant difference between the success rates in group 1 (58.3%) and group 2 (93.8%). In group 1, the mean prior duration of chalazion before treatment was significantly shorter in success cases than in failed cases. One patient with multiple chalazia in group 2 developed hypopigmentary skin changes at one treatment site. Subcutaneous extralesional triamcinolone acetonide injection was more effective than conservative treatment for chalazion.

    Eight adult female dairy goats received one subcutaneous administration of tulathromycin at a dosage of 2.5 mg/kg body weight. Blood and milk samples were assayed for tulathromycin and the common fragment of tulathromycin, respectively, using liquid chromatography/mass spectrometry. Pharmacokinetic disposition of tulathromycin was analyzed by a noncompartmental approach. Mean plasma pharmacokinetic parameters (±SD) following single-dose administration of tulathromycin were as follows: C(max) (121.54 ± 19.01 ng/mL); T(max) (12 ± 12-24 h); area under the curve AUC(0→∞) (8324.54 ± 1706.56 ng·h/mL); terminal-phase rate constant λz (0.01 ± 0.002 h⁻¹); and terminal-phase rate constant half-life t1/2λz (67.20 h; harmonic). Mean milk pharmacokinetic parameters (±SD) following 45 days of sampling were as follows: Cmax (1594 ± 379.23 ng/mL); Tmax (12 ± 12-36 h); AUC(0→∞) (72,250.51 ± 18,909.57 ng·h/mL); λz (0.005 ± 0.001 h⁻¹); and t(1/2λz) (155.28 h; harmonic). All goats had injection-site reactions that diminished in size over time. The conclusions from this study were that tulathromycin residues are detectable in milk samples from adult goats for at least 45 days following subcutaneous administration, this therapeutic option should be reserved for cases where other treatment options have failed, and goat milk should be withheld from the human food chain for at least 45 days following tulathromycin administration. © 2013 John Wiley & Sons Ltd.

    Retrospective case-control study using prospectively collected data. Evaluate the impact of liposomal bupivacaine (LB) on postoperative pain management and narcotic use following standardized single-level low lumbar transforaminal lumbar interbody fusion (TLIF). Poor pain control after surgery has been linked with decreased pain satisfaction and increased economic burden. Unfortunately, opioids have many limitations and side effects despite being the primary treatment of postoperative pain. LB may be a form of pre-emptive analgesia used to reduce the use of postoperative narcotics as evidence in other studies evaluating its use in single-level microdiskectomies. The infiltration of LB subcutaneously during wound closure was performed by a single surgeon beginning in July 2014 for all single-level lumbar TLIF spinal surgeries at Landstuhl Regional Medical Center. This cohort was compared against a control cohort of patients who underwent the same surgery by the same surgeon in the preceding 6 months. Statistical analysis was performed on relevant variables including: morphine equivalents of narcotic medication used (primary outcome), length of hospitalization, Visual Analog Scale pain scores, and total time spent on a patient-controlled analgesia (PCA) pump. A total of 30 patients were included in this study; 16 were in the intervention cohort and 14 were in the control cohort. The morphine equivalents of intravenous narcotic use postoperatively were significantly less in the LB cohort from day of surgery to postoperative day 3. Although the differences lost their statistical significance, the trend remained for total (oral and intravenous) narcotic consumption to be lower in the LB group. The patients who received the study intervention required an acute pain service consult less frequently (62.5% in LB cohort vs. 78.6% in control cohort). The amount of time spent on a PCA pump in the LB group was 31 hours versus 47 hours in the control group ( p =0.1506). Local

    This study was designed to investigate the pharmacokinetics of meloxicam, an oxicam class, nonsteroidal anti-inflammatory drug (NSAID), in ferrets. We determined the pharmacokinetic properties of a single subcutaneous dose of meloxicam (0.2 mg/kg) in nine male and nine female ferrets. Blood samples were collected by venipuncture of the cranial vena cava into heparinized syringes. Plasma meloxicam concentrations were determined by high-pressure liquid chromatography (HPLC). Pharmacokinetic variables were calculated using nonlinear mixed-effects modeling to take advantage of the population-based sampling scheme and to minimize sample volume collected per animal. Maximum plasma concentration, volume of distribution per absorption, and elimination half-life were 0.663 μg/mL, 0.21 L, and 11.4 h, respectively, for females and 0.920 μg/mL, 0.35 L, and 17.8 h, respectively, for males. Significant differences were found in each of the above parameters between male and female ferrets. Systemic clearance per absorption was not affected by gender and was 13.4 mL/h. Analgesic efficacy was not evaluated, but plasma meloxicam concentrations achieved in these animals are considered effective in other species. Sex differences in the pharmacokinetic behavior of meloxicam should be taken into consideration when treating ferrets. © 2014 John Wiley & Sons Ltd.

    Hydrocephalus is a complex disease that affects cerebrospinal fluid (CSF) dynamics and is very common in children. To this date, CSF shunting is still the standard treatment for childhood hydrocephalus, but, nevertheless, the effects of such an operation on the developing brain are widely unknown. To help overcome this, experimental models of CSF shunts are surely very useful tools. The objective of this study was to describe a feasible and reliable technique of an adapted ventricular-subcutaneous shunt for the treatment of kaolin-induced hydrocephalus in young rats. We developed a ventricular-subcutaneous shunt (VSCS) technique which was used in 31 Wistar young rats with kaolin-induced hydrocephalus. Hydrocephalus was induced at 7 days of age, and shunt implantation was performed 7 days later. Our technique used a 0.7-mm gauge polypropylene catheter tunneled to a subcutaneous pocket created over the animal's back and inserted into the right lateral ventricle. All animals were sacrificed 14 days after shunt insertion. Twenty-four rats survived and remained well until the study was ended. No major complications were seen. Their weight gain went back to normal. They all underwent ambulatory behavioral testing prior and after VSCS, which showed improvement in their motor skills. We have also obtained magnetic resonance (MR) scans of 16 pups confirming reduction of ventricular size after shunting and indicating effective treatment. Histopathological analysis of brain samples before and after shunting showed reversion of ependymal and corpus callosum disruption, as well as fewer reactive astrocytes in shunted animals. An experimental CSF shunt technique was devised. Excessive CSF of hydrocephalic rats is diverted into the subcutaneous space where it can be resorbed. This technique has a low complication rate and is effective. It might be applied to various types of experimental studies involving induction and treatment of hydrocephalus.

    IMPORTANCE B-cell depletion with the anti-CD20 antibody rituximab is highly effective for pemphigus vulgaris (PV) treatment. However,most patients experience relapse, and intravenous rituximab infusions are expensive. Therefore, cost-effective anti-CD20 therapies are desirable.OBSERVATIONS A compassionate-use investigational new drug protocol was approved to administer veltuzumab, a second-generation humanized anti-CD20 antibody, to a patient with refractory PV. Veltuzumab was administered as two 320-mg (188mg/m2) subcutaneous doses 2 weeks apart, resulting in complete remission of disease off therapy. The disease relapsed 2 years after treatment. A second cycle of subcutaneous veltuzumab, using the same dosage regimen, again induced complete remission off therapy, which remained at9 months. No serious adverse events occurred during 35 months of follow-up. Serum veltuzumab levels were 22 and 29 μg/mL 2 weeks after the first dose of each cycle, and the drug remained detectable in the serum for longer than 3 months. Relapse and response to veltuzumab generally correlated with desmoglein 3 enzyme-linked immunosorbent assay index values. Shortly after a relapse that occurred after a long-term remission, the patient demonstrated an elevated naive (CD19+CD27−) to memory (CD19+CD27+) B-cell ratio of 19.5 and transitional (CD19+CD24+CD38+) B-cell frequency of 12.5%.CONCLUSIONS AND RELEVANCE Subcutaneous veltuzumab may be a safe, effective, and more economical alternative to intravenous rituximab for PV therapy. Clinical trials of subcutaneous veltuzumab for PV are warranted.

    Full Text Available A 25-year-old man was diagnosised subcutaneous panniculitis-like T-cell lymphoma (SPTCL through biopsy of a nodule from the anterior chest. After the treatment with prednisone 90 mg 3 weeks and tapered off in 1 month, the disease released, but relapsed together with symptions of hemophagocytic syndrome eight months after the termination of prednisone. CHOEP recipe was given but with unsatisfactory result until cyclosporine was prescribed. Cyclosporine was removed 6 months later. There is no evidence of clinical relapse 1 year later. This case suggest that cyclosporine could be a selectable treatment even in relapsed SPTCL.

    Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, and in some instances, staining of clothes that may socially and psychologically impair affected individuals. Various types of surgical procedures have been developed for the treatment of axillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneous pulsed neodymium: yttrium-aluminum-garnet (Nd-YAG) laser treatment for the treatment of axillary osmidrosis. Twenty-nine patients with axillary osmidrosis were included in this study. Patients were categorized according to the results of an axillary malodor grading system, and a subcutaneous pulsed Nd-YAG laser was applied to all patients. The treatment area for the appropriate distribution of laser energy was determined using the iodine starch test (Minor's test) against a grid pattern composed of 2×2 cm squares. The endpoint of exposure was 300 to 500 J for each grid, depending on the preoperative evaluation results. The results were evaluated by measurement of axillary malodor both pre- and postoperatively using the grading system and iodine starch test. The average follow-up period was 12.8 months. Nineteen patients had a fair-to-good result and ten patients had poor results. The postoperative Minor's test demonstrated that there were remarkable improvements for patients with mild to moderate symptoms. Complications including superficial second degree burns (n=3) were treated in a conservative manner. A deep second degree burn (n=1) was treated by a surgical procedure. Subcutaneous pulsed Nd-YAG laser has many advantages and is an effective noninvasive treatment for mild to moderate axillary osmidrosis.

    Sudden cardiac death (SCD) risk can be managed by implantable cardioverter defibrillators (ICD). Defibrillation shocks can be delivered via ICD generator and/or intracardiac or subcutaneous coil configurations. We present our single-centre use of childhood ICDs. Twenty-three patients had ICD implantation, with median age and weight of 12.96 years and 41.35 kg. Indications included eight long QT; four hypertrophic cardiomyopathy; three Brugada syndrome; two idiopathic ventricular fibrillation; two post-congenital heart repair; two family history of SCD with abnormal repolarization; one catecholaminergic polymorphic ventricular tachycardia; and one left ventricle non-compaction. Twelve had out of hospital cardiac arrests prior to implantation. Techniques included 13 conventional ICD implants (pre-pectoral device with endocardial leads), 7 with subcutaneous defibrillation coils (sensing via epicardial or endocardial leads tunnelled to the ICD), and 3 with exclusive subcutaneous ICD (sensing and defibrillation via the same subcutaneous lead). Satisfactory defibrillation efficacy and ventricular arrhythmia sensing was confirmed at implantation. Follow-up ranged from 0.17 to 11.08 years. One child died with the ICD in situ. Ten children received appropriate shocks; five on more than one occasion. Five received inappropriate shocks (for inappropriate recognition of sinus tachycardia or supraventricular tachycardia). Five children underwent six further interventions; all had intracardiac leads. Innovative shock delivery systems can be used in children requiring an ICD. The insertion technique and device used need to accommodate the age and weight of the child, and concomitant need for pacing therapy. We have demonstrated effective defibrillation with shocks delivered via configurations employing subcutaneous coils in children.

    2015-01-01

    The demand for aesthetic body sculpting procedures has expanded precipitously in recent years. Subcutaneous adipose tissue (SAT) deposits of the central abdomen are especially common areas of concern for both males and females. To review the available literature regarding the underlying pathophysiology of subcutaneous fat accumulation in the abdominal area and available treatment options. A MEDLINE and Google Scholar search was performed accordingly. The preferential accumulation of SAT in the central abdomen is attributable to the reduced lipolytic sensitivity of its adipocytes. A number of therapeutic options are available for the treatment of central abdominal adiposity. Cryolipolysis, high-intensity focused ultrasound, nonthermal ultrasound, radiofrequency, and injection adipolysis lead to adipocyte destruction through multiple different mechanisms. Nonablative modalities such as injection lipolysis mobilize fat stores from viable adipocytes, although its effects may be curtailed in obese patients. Liposuction through tumescent technique, however, mechanically extricates SAT. Although tumescent liposuction remains the gold standard for SAT removal, less invasive ablative and nonablative options for targeting localized deposits of adipose tissue now permeate the aesthetic marketplace. Limited results associated with these modalities mandate multiple sessions or combination treatment paradigms.

  20. Bleeding risk during treatment of acute thrombotic events with subcutaneous LMWH compared to intravenous unfractionated heparin; a systematic review.

    Directory of Open Access Journals (Sweden)

    Giorgio Costantino

    Full Text Available BACKGROUND: Low Molecular Weight Heparins (LMWH are at least as effective antithrombotic drugs as Unfractionated Heparin (UFH. However, it is still unclear whether the safety profiles of LMWH and UFH differ. We performed a systematic review to compare the bleeding risk of fixed dose subcutaneous LMWH and adjusted dose UFH for treatment of venous thromboembolism (VTE or acute coronary syndromes (ACS. Major bleeding was the primary end point. METHODS: Electronic databases (MEDLINE, EMBASE, and the Cochrane Library were searched up to May 2010 with no language restrictions. Randomized controlled trials in which subcutaneous LMWH were compared to intravenous UFH for the treatment of acute thrombotic events were selected. Two reviewers independently screened studies and extracted data on study design, study quality, incidence of major bleeding, patients' characteristics, type, dose and number of daily administrations of LMWH, co-treatments, study end points and efficacy outcome. Pooled odds ratios (OR and 95% confidence intervals (CI were calculated using the random effects model. RESULTS: Twenty-seven studies were included. A total of 14,002 patients received UFH and 14,635 patients LMWH. Overall, no difference in major bleeding was observed between LMWH patients and UFH (OR = 0.79, 95% CI 0.60-1.04. In patients with VTE LMWH appeared safer than UFH, (OR = 0.68, 95% CI 0.47-1.00. CONCLUSION: The results of our systematic review suggest that the use of LMWH in the treatment of VTE might be associated with a reduction in major bleeding compared with UFH. The choice of which heparin to use to minimize bleeding risk must be based on the single patient, taking into account the bleeding profile of different heparins in different settings.

    Bacterial pneumonia in goats is usually caused by Mannheimia haemolytica and Pasteurella multocida. Another important infection disease in lactating goats is intramammary infection producing mastitis, usually associated with coagulase-negative Staphylococcus spp. However, treatment of bacterial pneumonia in goats not affected by mastitis problems should be restricted to antimicrobials with scant penetration to milk in order to avoid long withdrawal times. Ceftiofur is a third-generation cephalosporin antimicrobial with activity against various gram-positive and gram-negative, aerobic and anaerobic bacteria encountered by domestic animals. The objectives of the present study were to establish the serum concentration-time profile for ceftiofur in lactating goats after intravenous, subcutaneous and a SC-long-acting ceftiofur formulation; to determine ceftiofur penetration into milk; to determine in vitro and ex vivo activity of ceftiofur establishing MIC, MBC, MPC and time-kill profiles against field strains of M. haemolytica and finally to calculate the main surrogate markers of efficacy. The pharmacokinetics studies revealed an optimal PK properties for the SC-LA formulation tested. Ceftiofur was well absorbed following SC and SC-LA administration, with absolute bioavailabilities (F) of 85.16 and 84.43 %, respectively. After ceftiofur analysis from milk samples, no concentrations were found at any sampling time. The MIC, MBC and MPC data of ceftiofur against five M. haemolytica strains isolated from goats affected by pneumonia were tested showing excelent sensitivity of ceftiofur against this pathogen. For PK-PD analysis, ratios were calculated suggesting a high level of bacterial kill against the five strains of M. haemolytica tested. The systemic ceftiofur exposure achieved in lactating goats following IV, SC and especially with the SC-LA administration is consistent with the predicted PK-PD ratios needed for a positive therapeutic outcome for M. haemolytica

    Full Text Available Diabetes mellitus (DM is an important health problem that should be treated efficiently because of its high prevalence and high morbidity and mortality due to its complications. In patients with DM, the application of a treatment which provides physiologic insulin secretion as such in healthy individuals is directly related with the prevention of diabetes complications. Insulin analogs, which were developed in recent years and shown to have pharmacokinetic and pharmacodynamic superiority to human insulin, have made it possible to obtain natural insulin pattern in the body. In addition to development of insulin analogs, introduction of insulin application method of “continuous subcutaneous insulin infusion” (insulin pump has led a new era in the treatment of DM. In this review, treatment of type 1 and 2 DM patients with insulin analogs, particularly insulin aspart, applied with insulin pump was discussed in the light of the current literature.

    Background: Primary focal axillary hyperhidrosis is a chronic distressing disorder affecting both the sexes. When the condition is refractory to conservative management, we should go for more promising therapies like intradermal botulinum toxin A (BtxA) injections in the axilla, and surgical therapies like subcutaneous curettage of sweat glands. Aims and Objectives: The aim of this study is to compare the efficacy, safety and duration of action of intradermal BtxA injections in one axilla and subcutaneous curettage of sweat glands in the other axilla of the same patient with axillary hyperhidrosis. Materials and Methods: Twenty patients (40 axillae) received intradermal BtxA injections on the right side (20 axillae) and underwent tumescent subcutaneous curettage of sweat glands on the left side (20 axillae). Sweat production rate was measured using gravimetry analyses at baseline and at 3 months after the procedure. Subjective analyses were done using hyperhidrosis disease severity scale (HDSS) score at baseline, at 3rd and 6th month after the procedure. Results: At 3 months post-treatment, the resting sweat rate in the toxin group improved by 80.32% versus 79.79% in the subcutaneous curettage method (P = 0.21). Exercise-induced sweat rate in the toxin group improved by 88.76% versus 88.8% in the subcutaneous curettage group (P = 0.9). There was a significant difference in the HDSS score after treatment with both the modalities. There were no adverse events with BtxA treatment compared to very minor adverse events with the surgical method. Conclusion: Both intradermal BtxA injections and tumescent subcutaneous curettage of sweat glands had a significant decrease in the sweat rates with no significant difference between the two modalities. Hence, in resource poor settings where affordability of BtxA injection is a constraint, subcutaneous curettage of sweat glands can be preferred which has been found equally effective with no or minimal adverse events.

    Background Immediate implant reconstruction after a conservative mastectomy is an attractive option made easier by prosthetic devices. Titanized polypropylene meshes are used as a hammock to cover the lower lateral implant pole. We conducted a prospective nonrandomized single-institution study of reconstructions using titanium-coated meshes either in a standard muscular mesh pocket or in a complete subcutaneous approach. The complete subcutaneous approach means to wrap an implant with titaniz...

    Hyaluronidase is a key preventative treatment against vascular complications of hyaluronic acid (HA) filler injection, but the degradation profile of HA to hyaluronidase is limited, and the comparison between intra-arterial and subcutaneous injections of hyaluronidase has not been studied. To evaluate HA degradation to hyaluronidase and compare different treatments between intra-arterial and subcutaneous testicular hyaluronidase injections. The authors observed HA degradation to hyaluronidase in vitro via microscopic examination and particle analysis. Rabbit ears were used for the in vivo study. There were 2 control groups receiving ligation or HA-induced embolism in the arteries, respectively, and 2 intervention groups receiving hyaluronidase treatments in different regions. The laser Doppler blood perfusion monitoring measurements were made at defined time points, and biopsies were taken on Day 2. Nearly, all of the HAs degraded in vitro at the 1-hour time point. Subcutaneous hyaluronidase treatment showed better recovery of blood perfusion. Histology showed severe inflammation in the embolism group and mild inflammation in the intervention groups. A complete enzymatic degradation of HA filler to hyaluronidase needs a certain time, and subcutaneous hyaluronidase treatment may be the better option.

    Highlights: • No imaging marker for treatment response of spondylodiscitis (SD) has been proposed. • Volume changes of subcutaneous fluid collection (SFC) had significant correlation with changes of C-reactive protein (CRP). • SFC can be used as an imaging marker for treatment response of SD on magnetic resonance imaging (MRI). - Abstract: Purpose: To evaluate prevalence of subcutaneous fluid collection (SFC) in infectious thoracolumbar spondylodiscitis (SD) compared with control patients and to investigate correlation between volume changes of SFC and treatment response of SD. Materials and methods: This retrospective study was approved by our institutional review board. From April 2011 to March 2012, 49 patients (24 SD and 25 non-SD patients) were enrolled. Prevalence of SFC was evaluated respectively for SD and non-SD patients using magnetic resonance imaging (MRI) on the sagittal short tau inversion recovery (STIR) imaging or fat-saturated T2-weighted imaging (T2WI), and compared. In SD patients with SFC, correlation was investigated between SFC volume on the 1st MRI and initial clinical status. The same analysis was conducted also for SFC volume changes from the 1st to 2nd or last MRI. Results: SFC was found in 20 patients with SD (83.3%) and 3 non-SD patients (12%) with significant difference (p < .001). In 20 SD patients with SFC, 17 patients had follow-up MRI. For the 1st MRI, no significant correlation was found between volume of SFC and initial status of patients, including body weight, body mass index (BMI), white blood cell (WBC), and erythrocyte sedimentation rate (ESR). However, significant positive correlations were found between changes of C-reactive protein (CRP) and SFC volume from the 1st to 2nd as well as from the 1st to the last MRI (each p < .05). Conclusion: SD patients had significantly higher prevalence of SFC than non-SD patients. Volume changes of SFC had significant correlation with changes of CRP, which can be used as an imaging

    2018-03-22

    Diabetic footfoot ulcer (DFU) is a serious complication of diabetes mellitus, and possibly the major morbidity of the diabetic foot. It is the most common foot injury in diabetic patients and can lead to lower-extremity amputation. Management of DFU requires a systematic knowledge of the major risk factors for amputation, frequent routine evaluation, scrupulous preventive maintenance, and correction of peripheral arterial insufficiency. Carboxytherapy refers to the subcutaneous injection of CO2 to improve the microcirculation and promote wound-healing by stimulating the microcirculation. Since optimal ulcer-healing requires adequate tissue perfusion, it is considered that carboxytherapy could be useful in the treatment of DFU. The present prospective clinical study included 40 patients with different sizes and types of chronic DFU. In addition to cleaning of the wound, antibiotics and debridement as necessary, the treatment protocol included blood sugar control, medication, healthy habits, no weight-bearing, and carboxytherapy. The results showed that this treatment that included carboxytherapy promoted wound-healing and prevented amputation. These positive effects should be confirmed through a complete study that includes different clinical and instrumental parameters.

    The goal of the present study was to evaluate the potential use of slow release buprenorphine in sheep. Twelve adult female sheep (6 Dorset and 6 Suffolk, 12 months of age) were used for this project and were divided into 2 experimental groups (n = 6/group comprising 3 Dorset and 3 Suffolk sheep). Sustained release (SR) buprenorphine was administered subcutaneously in the scapular region at a concentration of 0.1 mg/kg body weight (BW) for group 1 and of 0.05 mg/kg BW for group 2. Following blood collections at selected time points, plasma concentrations of buprenorphine was performed by tandem liquid chromatograph-mass spectrometry. Mean buprenorphine concentration was above 0.1 ng/mL at 48 h up to 192 h post-injection for group 1 and it was above 0.1 ng/mL at 48 h up to 72 h post-injection for group 2. In conclusion, a long lasting potential analgesic plasma level of buprenorphine is attained following a single subcutaneous injection of 0.1 mg/kg BW of SR buprenorphine in sheep. However the effective analgesic plasma threshold still needs to be determined in sheep.

    Full Text Available Background Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, andin some instances, staining of clothes that may socially and psychologically impair affectedindividuals. Various types of surgical procedures have been developed for the treatment ofaxillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneouspulsed neodymium: yttrium-aluminum-garnet (Nd-YAG laser treatment for the treatment ofaxillary osmidrosis.Methods Twenty-nine patients with axillary osmidrosis were included in this study. Patientswere categorized according to the results of an axillary malodor grading system, and asubcutaneous pulsed Nd-YAG laser was applied to all patients. The treatment area for theappropriate distribution of laser energy was determined using the iodine starch test (Minor’stest against a grid pattern composed of 2×2 cm squares. The endpoint of exposure was300 to 500 J for each grid, depending on the preoperative evaluation results. The resultswere evaluated by measurement of axillary malodor both pre- and postoperatively using thegrading system and iodine starch test.Results The average follow-up period was 12.8 months. Nineteen patients had a fair-togoodresult and ten patients had poor results. The postoperative Minor’s test demonstratedthat there were remarkable improvements for patients with mild to moderate symptoms.Complications including superficial second degree burns (n=3 were treated in a conservativemanner. A deep second degree burn (n=1 was treated by a surgical procedure.Conclusions Subcutaneous pulsed Nd-YAG laser has many advantages and is an effectivenoninvasive treatment for mild to moderate axillary osmidrosis.

Bisphosphonate treatment for bone metastases is frequently administered via intravenous infusion, while a newer treatment is administered as a subcutaneous injection. This study estimated the impact of these treatment modalities on health state preference. Methods: Participants from the UK general population completed time trade-off interviews to assess the utility of health state vignettes. Respondents first rated a health state representing cancer with bone metastases. Subsequent health states added descriptions of treatment modalities (ie, injection or infusion to this basic health state. The two treatment modalities were presented with and without chemotherapy, and infusion characteristics were varied by duration (30 minutes or 2 hours and renal monitoring. Results: A total of 121 participants completed the interviews (52.1% female, 76.9% white. Cancer with bone metastases had a mean utility of 0.40 on a standard utility scale (1 = full health; 0 = dead. The injection, 30-minute infusion, and 2-hour infusion had mean disutilities of −0.004, −0.02, and −0.04, respectively. The mean disutility of the 30-minute infusion was greater with renal monitoring than without. Chemotherapy was associated with substantial

    2017-06-01

    Full Text Available Spinal muscular atrophy (SMA is a recessive disease caused by mutations in the SMN1 gene, which encodes the protein survival motor neuron (SMN, whose absence dramatically affects the survival of motor neurons. In humans, the severity of the disease is lessened by the presence of a gene copy, SMN2. SMN2 differs from SMN1 by a C-to-T transition in exon 7, which modifies pre-mRNA splicing and prevents successful SMN synthesis. Splice-switching approaches using antisense oligonucleotides (AONs have already been shown to correct this SMN2 gene transition, providing a therapeutic avenue for SMA. However, AON administration to the CNS presents additional hurdles. In this study, we show that systemic delivery of tricyclo-DNA (tcDNA AONs in a type III SMA mouse augments retention of exon 7 in SMN2 mRNA both in peripheral organs and the CNS. Mild type III SMA mice were selected as opposed to the severe type I model in order to test tcDNA efficacy and their ability to enter the CNS after maturation of the blood brain barrier (BBB. Furthermore, subcutaneous treatment significantly improved the necrosis phenotype and respiratory function. In summary, our data support that tcDNA oligomers effectively cross the blood-brain barrier and offer a promising systemic alternative for treating SMA.

    Full Text Available Objective: Current goals of treatment of diabetes are to achieve near-normal glycemia, minimize the risk of severe hypoglycemia, limit excessive weight gain, and to improve quality of life. Insulin pump or continuous subcutaneous insulin infusion (CSII therapy provides a treatment option to aid in achieving all of these goals. CSII is a viable alternative to multiple daily injections (MDI therapy for patients with diabetes who are capable and motivated. In this study, we aimed to compare the diabetic control and treatment satisfaction in our patients using CSII and MDI. Materials and Methods: Fifty patients with type 1 diabetes, who had been followed between 2005-2008, were enrolled in the study. Changes in biomedical outcomes (glycated haemoglobin; HbA1c, hypoglycaemia, and weigth gain pre-CSII, during the last year and at the end of the study were analyzed retrospectively. For treatment satisfaction and compliance, we used a questionnaire containing 12 questions. The patients were divided into two groups according to MDI or CSII therapy use for least one year: Group 1 using CSII (n:27 and Group 2 using MDI (n:23. Results: There was no significant difference between the last HbA1c levels in both groups. In CSII group, decrease in HbA1c was 0.79% for average follow-up of 1.66 years ( 9.19%±2.23; 8.40%±1.17. When the two groups were compared in terms of hypoglycemia rates and weight gain over the last year, no statistically significant difference was found, but in CSII group, hypoglycemia rates were lower. Finally, CSII group demonstrated a higher treatment satisfaction rate and higher compliance, while a negative correlation was detected between frequency of home blood glucose monitoring and HbA1c levels in all patients. Conclusion: CSII therapy is effective in improving glycemic control with higher treatment satisfaction when compared with MDI therapy in selected type 1 diabetic patients. Turk Jem 2010; 14: 80-4

    Photodynamic therapy (PDT) has developed into a mature technology over the past several years, and is currently being exploited for the treatment of a variety of cancerous tumors, and more recently for age-related wet macular degeneration of the eye. However, there are still some unresolved problems with PDT that are retarding a more general acceptance in clinical settings, and thus, for the most part, the treatment of most cancerous rumors still involves some combination of invasive surgery, chemotherapy and radiation treatment, particularly subcutaneous tumors. Currently approved PDT agents are activated in the Visible portion of the spectrum below 700 nm, Laser light in this spectral region cannot penetrate the skin more than a few millimeters, and it would be more desirable if PDT could be initiated deep in the Near-infrared (NIR) in the tissue transparency window (700-1000 nm). MPA Technologies, Inc. and Rasiris, Inc. have been co-developing new porphyrin PDT designed to have greatly enhanced intrinsic two-photon cross-sections (>800 GM units) whose two-photon absorption maxima lie deep in the tissue transparency window (ca. 780-850 nm), and have solubility characteristics that would allow for direct IV injection into animal models. Classical PDT also suffers from the lengthy time necessary for accumulation at the tumor site, a relative lack of discrimination between healthy and diseased tissue, particularly at the tumor margins, and difficulty in clearing from the system in a reasonable amount of time post-PDT. We have recently discovered a new design paradigm for the delivery of our two-photon activated PDT agents by incorporating the porphyrins into a triad ensemble that includes a small molecule targeting agent that directs the triad to over-expressed tumor receptor sites, and a NIR one-photon imaging agent that allows the tracking of the triad in terms of accumulation and clearance rates. We are currently using these new two-photon PDT triads in efficacy

    Allergic rhinitis (AR) triggered by grass pollen is a common disease, affecting millions of people worldwide. Treatment consists of symptom-alleviating drugs, such as topical corticosteroids or antihistamines. Another option is potentially curative immunotherapy, currently available as sublingual and subcutaneous treatment. We investigated the potential differences in the prevalence and severity of adverse events related to subcutaneous and sublingual immunotherapy (SLIT) against grass pollen-induced AR. A thorough literature search was performed with PubMed and EMBASE. The findings were compared with the available summaries of product characteristics (SPC) and with commercial pharmacology databases (Micromedex). The majority of available safety data originate from registered products of standardized allergens. A surprisingly large percentage of drugs, especially those used in the United States, have no systematically collected safety data. No sufficiently powered randomized trials comparing sublingual and subcutaneous immunotherapy (SCIT) were available, but general safety assessments indicate that sublingual tablet treatment is safer than subcutaneous treatment. Not all commonly used immunotherapy drugs are officially registered, and not all have systematically collected safety data. This is especially true for older drugs used in the United States. In contrast, newer drugs that have undergone extensive clinical testing have better documentation, but unified collection of safety data is still lacking. Considering the evidence available, most drugs elicit similar side effects from the same organ systems, and symptoms from the sublingual drug classes are probably less severe. However, a head-to-head comparison of safety and efficacy is lacking. © 2015 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    The GLP-1 receptor agonist liraglutide is marketed for obesity treatment where it induces body weight reduction possibly via the hypothalamus, which regulates energy homeostasis. In animal studies, acute liraglutide treatment triggers satiety, weight loss and activates thermogenesis in adipose tissue. However, the precise mechanisms how liraglutide affects in particular chronic weight loss are still under investigation. We aimed to evaluate whether chronic hypothalamic or chronic subcutaneous administration of liraglutide induces sustained weight loss through altered adipose tissue function and to what extent hypothalamic neuronal appetite regulators are involved in the liraglutide-induced weight loss in healthy lean rats on a normal diet. We continuously administered liraglutide either intrahypothalamically (10 μg per day) or subcutaneously (200 μg kg -1 per day) for 28 days to lean Sprague Dawley rats (n=8 each). We assessed changes in body weight, adipose tissue mass, adipocyte size and adipose tissue volume in the abdominal region by using micro-CT. We analyzed genetic expression patterns of browning, thermogenic and adipocyte differentiation regulators in adipose tissues as well as particular neuronal appetite regulators in the hypothalamus. Intrahypothalamic liraglutide administration induced an 8% body weight reduction at day 9 compared with the control group (Pbody weight loss at day 9 compared with subcutaneous liraglutide treatment (Pbody weight and fat mass loss most likely mediated by the hypothalamic melanocortin system rather than by adipose tissue browning or improved thermogenesis.

    Full Text Available The aim of this study was to investigate whether tolerance-induced protection of islets in the renal subcapsular space can also prevent subcutaneous allogeneic islets from being rejected. We used bone marrow stem cells from C57BL/6 (H2b mice to construct donor chimerism in conditioned diabetic BALB/c (H2d mice and investigated the effect of donor chimerism on engraftment and survival of subcutaneously transplanted allogeneic islets in streptozotocin-induced diabetic mice. We also studied the anti-inflammatory effect of mesenchymal stem cell on islet engraftment. Full but not low-grade or no donor chimerism was associated with successful engraftment of allogeneic islets and restoration of normoglycemia in the treated diabetic mice. The temporary hyperglycemia was 11 ± 1 versus 19 ± 5 days (p<0.05 for the mice with full donor chimerism with transplanted islets in the renal subcapsular space versus the subcutaneous space, respectively. Cotransplantation of mesenchymal stem cell did not enhance alloislet engraftment. Full multilineage donor chimerism was associated with a higher transient expansion of CD11b+ and Gr-1+ myeloid progenitor cells and effector memory CD4 and CD8 T cells. In conclusion, full donor chimerism protected both renal subcapsular and subcutaneous allogeneic islets in this rodent transplantation model.

    Full Text Available Suzanne Skoda-Smith, Troy R Torgerson, Hans D OchsSeattle Children’s Research Institute and Department of Pediatrics, University of Washington, Seattle, WashingtonAbstract: Antibody deficiency is the most frequently encountered primary immunodeficiency disease (PIDD and patients who lack the ability to make functional immunoglobulin require life-long replacement therapy to prevent serious bacterial infections. Human serum immunoglobulin manufactured from pools of donated plasma can be administered intramuscularly, intravenously or subcutaneously. With the advent of well-tolerated preparations of intravenous immunoglobulin (IVIg in the 1980s, the suboptimal painful intramuscular route of administration is no longer used. However, some patients continued to experience unacceptable adverse reactions to the intravenous preparations, and for others, vascular access remained problematic. Subcutaneously administered immunoglobulin (SCIg provided an alternative delivery method to patients experiencing difficulties with IVIg. By 2006, immunoglobulin preparations designed exclusively for subcutaneous administration became available. They are therapeutically equivalent to intravenous preparations and offer patients the additional flexibility for the self-administration of their product at home. SCIg as replacement therapy for patients with primary antibody deficiencies is a safe and efficacious method to prevent serious bacterial infections, while maximizing patient satisfaction and improving quality of life.Keywords: subcutaneous immunoglobulin, primary immunodeficiency disease, antibody deficiency, X-linked agammaglobulinemia, common variable immune deficiency

    Cases of subcutaneous fat necrosis of the newborn (SCFN) and neonatal cold panniculitis have been reported most often secondary to perinatal distress or hypothermia. We present a case of a newborn infant who developed erythematous, indurated plaques on both cheeks and right shoulder following ice pack application for supraventricular tachycardia. The distinction between SCFN and cold panniculitis is important as SCFN may have complications such as hypercalcemia, whereas cold panniculitis is not associated with such sequelae. Clinicians should be aware of the diagnostic similarities and differences between these two conditions because of differences in potential serious sequelae.

The former task is successfully solved by radical mastectomy whereas it is rather difficult to restore the breast because a specialist has to compensate for the whole volume of its tissue and to form a nipple-areolar complex (NAC and a submammary fold. Subcutaneous mastectomy with and without NAC preservation optimally solves both tasks: its performance, by simultaneously maintaining the high level of radicalism, substantially makes primary breast repair easier and yields a better esthetic result.

    "Psychological insulin resistance" (PIR) is an obstacle to insulin treatment in type 2 diabetes, and patients' expectations regarding alternative ways of insulin delivery are poorly understood. PIR and beliefs regarding treatment alternatives were analyzed in patients with type 2 diabetes (n=532; mean glycated hemoglobin, 68±12 mmol/mol [8.34±1.5%]) comparing oral antidiabetes treatment, subcutaneous insulin injections, or inhaled insulin. Questionnaires were used to assess barriers to insulin treatment (BIT), generic and diabetes-specific quality of life (Short Form 36 and Problem Areas in Diabetes, German version), diabetes knowledge, locus of control (Questionnaire for the Assessment of Diabetes-Specific Locus of Control, in German), coping styles (Freiburg Questionnaire of Illness Coping, 15-Items Short Form), self-esteem (Rosenberg Self-Esteem Scale, German version), and mental disorders (Patient Health Questionnaire, German version). Patients discussed treatment optimization options with a physician and were asked to make a choice about future diabetes therapy options in a two-step treatment choice scenario. Step 1 included oral antidiabetes drugs or subcutaneous insulin injection (SCI). Step 2 included an additional treatment alternative of inhaled insulin (INH). Subgroups were analyzed according to their treatment choice. Most patients perceived their own diabetes-related behavior as active, problem-focused, internally controlled, and oriented toward their doctors' recommendations, although their diabetes knowledge was limited. In Step 1, rejection of the recommended insulin was 82%, and in Step 2, it was 57%. Fear of hypoglycemia was the most important barrier to insulin treatment. Patients choosing INH (versus SCI) scored higher regarding fear of injection, expected hardship from insulin therapy, and BIT-Sumscore. The acceptance of insulin is very low in type 2 diabetes patients. The option to inhale insulin increases the acceptability for some but

    Teriparatide(recombinant human PTH1-34, 20 μg daily subcutaneous injection)has been approved for osteoporosis patients at high risk of fracture in many countries including Japan. Teriparatide daily injection therapy has been reported to increase BMD, improve microarchitecture of bone, and reduce the risk of new vertebral fractures and that of non-vertebral fractures. Pharmakokinetic(PK)study after a single Teriparatide injection of the daily dose in healthy Japanese postmenopausal women(n=18)revealed very rapid achievement of peak blood level(median of tmax=0.25 hr)followed by fast disappearance from the blood(mean t1/2=0.708 hr, n=17). Consistent with these PK characteristics, a rapid increase in bone formation marker and later increase in bone resorption marker has previously been observed, which was described as a bone anabolic window. More recently, once weekly subcutaneous injection of teriparatide acetate(56.5 μg)has been reported to reduce the risk of new vertebral fractures compared with placebo and has been approved in Japan. PK study after injection of the higher weekly dose in healthy Japanese postmenopausal women(n=10)revealed a relatively slow achievement of the peak blood level(mean tmax=0.875 hr)compared to daily injections, followed by relatively slow disappearance from the blood(mean t1/2=1.295 hr). Consistent with these PK characteristics, an initial(teriparatide treatment needs to be clarified.

    Immediate implant reconstruction after a conservative mastectomy is an attractive option made easier by prosthetic devices. Titanized polypropylene meshes are used as a hammock to cover the lower lateral implant pole. We conducted a prospective nonrandomized single-institution study of reconstructions using titanium-coated meshes either in a standard muscular mesh pocket or in a complete subcutaneous approach. The complete subcutaneous approach means to wrap an implant with titanized mesh in order to position the implant subcutaneously and spare muscles. Between November 2011 and January 2014, we performed immediate implant breast reconstructions after conservative mastectomies using TiLoop® Bra, either with the standard retropectoral or with a prepectoral approach. Selection criteria included only women with normal Body Mass Index (BMI), no large and very ptotic breasts, no history of smoking, no diabetes, and no previous radiotherapy. We analyzed short-term outcomes of such procedures and compared the outcomes to evaluate implant losses and surgical complications. A total of 73 mastectomies were performed. Group 1 comprised 29 women, 5 bilateral procedures, 34 reconstructions, using the standard muscular mesh pocket. Group 2 comprised 34 women, 5 bilateral procedures, 39 reconstructions with the prepectoral subcutaneous technique. Baseline and oncologic characteristics were homogeneous between the two groups. After a median follow-up period of 13 and 12 months, respectively, no implant losses were recorded in group 1, and one implant loss was recorded in group 2. We registered three surgical complications in group 1 and two surgical complications in group 2. Titanium-coated polypropylene meshes, as a tool for immediate definitive implant breast reconstruction, resulted as safe and effective in a short-term analysis, both for a retropectoral and a totally subcutaneous implant placement. Long-term results are forthcoming. A strict selection is mandatory to

    To confirm the better analgesic effect of subcutaneous penetration needling of otopoints for treatment of scapulohumeral periarthritis (SHPA) patients. Sixty-six SHPA patients were randomized into penetration-needling group (n = 33) and straight needling group (n = 33) by using pairing principle according to the sex and state of disease. Penetration needling was adopted for patients of penetration-needling group, while straight needling was used for those of straight needling group. Simplified McGill Scale was used to evaluate the patients' pain reactions. The pain integral scores were analyzed by using sequential test and pairing t test. Sequential test showed that the analgesic effect of penetration needling was significantly superior to that of straight needling 30 min after the treatment (P straight needling (P straight needling in the treatment of scapulohumeral periarthritis.

    Impaired mineral homeostasis affecting calcium, phosphate, and magnesium is a result of parathyroid hormone (PTH) deficiency in hypoparathyroidism. The current standard of treatment with active vitamin D and oral calcium does not control levels of these major minerals. Recombinant full-length human PTH 1-84 (rhPTH[1-84]) is being developed for the treatment of hypoparathyroidism. The goal of this study was to investigate the pharmacokinetics and pharmacodynamics of a single subcutaneous injection of rhPTH(1-84) in patients with hypoparathyroidism. This was an open-label, dose-escalating study of single subcutaneous administration of 50 µg and then 100 µg of rhPTH(1-84). Enrolled patients (age range, 25-85 years) had ≥12 months of diagnosed hypoparathyroidism defined according to biochemical evidence of hypocalcemia with concomitant low-serum intact PTH and were taking doses ≥1000 mg/d of oral calcium and ≥0.25 µg/d of active vitamin D (oral calcitriol). The patient's prescribed dose of calcitriol was taken the day preceding but not on the day of or during the 24 hours after rhPTH(1-84) administration. Each patient received a single 50-µg rhPTH(1-84) dose, had at least a 7-day washout interval, and then received a single 100-µg rhPTH(1-84) dose. The following parameters were assessed: plasma PTH; serum and urine total calcium, magnesium, phosphate, and creatinine; and urine cyclic adenosine monophosphate. After administration of rhPTH(1-84) 50 µg (n = 6) and 100 µg (n = 7), the approximate t½ was 2.5 to 3 hours. Plasma PTH levels increased rapidly, then declined gradually back to predose levels at ~12 hours. The median AUC was similar with calcitriol and rhPTH(1-84) for serum 1,25-dihydroxyvitamin D (calcitriol, 123-227 pg · h/mL; rhPTH[1-84], 101-276 pg · h/mL), calcium (calcitriol, 3.3-3.7 mg · h/dL; rhPTH[1-84], 3.3-7.6 mg · h/dL), and magnesium (calcitriol, 0.7-0.9 mg · h/dL; rhPTH[1-84], 1.3-2.8 mg · h/dL).

To investigate the efficacy and safety of the treatment of the newly diagnosed multiple myeloma (MM patients with the therapy of subcutaneous (subQ administration of bortezomib and dexamethasone plus thalidomide (VTD regimen. Methods. A total of 60 newly diagnosed MM patients were analyzed. 30 patients received improved VTD regimen (improved VTD group with the subQ injection of bortezomib and the other 30 patients received conventional VTD regimen (VTD group.The efficacy and safety of two groups were analyzed retrospectively. Results. The overall remission (OR after eight cycles of treatment was 73.3% in the VTD group and 76.7% in the improved VTD group (P>0.05. No significant differences in time to 1-year estimate of overall survival (72% versus 75%, P=0.848 and progression-free survival (median 22 months versus 25 months; P=0.725 between two groups. The main toxicities related to therapy were leukopenia, neutropenia, thrombocytopenia, asthenia, fatigue, and renal and urinary disorders. Grade 3 and higher adverse events were significantly less common in the improved VTD group (50% than VTD group (80%, P=0.015. Conclusions. The improved VTD regimen by changing bortezomib from intravenous administration to subcutaneous injection has noninferior efficacy to standard VTD regimen, with an improved safety profile and reduced adverse events.

    Full Text Available Background: This study was designed to compare two methods of surgery, anterior subcutaneous transposition (ASCT and anterior submuscular transposition (ASMT of the ulnar nerve in treatment of cubital tunnel syndrome. Materials and Methods: This randomized trial study was conducted from October 2008 to March 2009 in the Department of Orthopedic Surgery at University Hospital. Forty-eight patients with confirmed cubital tunnel syndrome were randomized in two groups, and each patient received one of two different surgical treatment methods, either ASCT (n = 24 or ASMT (n = 24. In the ASCT technique, the ulnar nerve was transposed and retained in the subcutaneous bed, whereas in the ASMT, the nerve was retained deep in the transected muscular complex, near the median nerve. Patient outcomes, including pain, sensation, muscle strength, and muscle atrophy were compared between groups. Results: The two groups were similar in baseline characteristics. However, those treated with ASMT had a statistically significant reduction in their pain levels compared with ASCT (21 (87.5% vs 8 (33.3%, P 0.05. Conclusions: Our results indicate that ASMT are more efficient than ASCT for managing cubital tunnel syndrome. In patients who had ASMT, there were significant reductions of pain compared with ASCT.

    Full Text Available Katherine A Lewis, Erica A EugsterDepartment of Pediatrics, Indiana University School of Medicine, Riley Hospital for Children, Indianapolis, USAAbstract: In 2007, a hydrogel histrelin implant was approved for the treatment of children with central precocious puberty (CPP. Children with CPP commonly have reduced height potential due to premature closure of the epiphyseal growth plates from exposure to sex steroids. Gonadotropin-releasing hormone analog (GnRHa treatment halts puberty and allows for improvement of adult height. A hydrogel implant delivery system utilizing the potent GnRHa, histrelin, was first developed for use in men with prostate cancer. A once yearly histrelin subcutaneous implant was subsequently developed for the treatment of children with CPP. Studies to date have demonstrated safety, tolerability, and effectiveness of this treatment option in patients treated up to 2 years. The most common adverse effects of the implant relate to implant site pain or bruising. Cost of this treatment seems comparable to somewhat higher than the commonly used GnRHa treatment option, depot leuprolide. While long term studies are needed to establish continued efficacy and safety beyond 2 years of treatment, the histrelin implant appears to be an attractive option for GnRHa treatment in patients with CPP.Keywords: central precocious puberty, histrelin, implant, gonadotropin-releasing-hormone analogs

    . By the end of the study, all participants had developed antibodies against polyethylene glycol, and some against phenylalanine ammonia lyase as well. Drug concentrations peaked about 89-106 h after administration of the highest dose. Treatment seemed to be effective at reducing blood phenylalanine in all five participants who received the highest dose (mean reduction of 54·2% from baseline), with a nadir about 6 days after injection and an inverse correlation between drug and phenylalanine concentrations in plasma. Phenylalanine returned to near-baseline concentrations about 21 days after the injection. Subcutaneous administration of rAvPAL-PEG in a single dose of up to 0·100 mg/kg was fairly safe and well tolerated in adult patients with phenylketonuria. At the highest dose tested, rAvPAL-PEG reduced blood phenylalanine concentrations. In view of the development of antibodies against polyethylene glycol (and in some cases against phenylalanine ammonia lyase), future studies are needed to assess the effect of repeat dosing.

    Full Text Available Postural Tachycardia Syndrome (PoTS represents a disorder of the autonomic nervous system that results in symptoms of orthostatic intolerance. Despite having a severe impact on the patient’s quality of life, the current treatment options for PoTS are based on limited evidence. Subsequently, this results in clinicians having to utilise a variety of treatment regimens in the hope of successfully providing symptomatic relief. However, the options available for PoTS are not without significant side effects that can worsen an already debilitating condition. Our cases provide a further novel treatment option for clinicians to consider in PoTS refractory to established treatments.

    This work reports the experience with use of continuous subcutaneous insulin infusion (CSII) in 112 type 1 diabetic patients followed up for 7 years and previously treated with multiple daily insulin injections (MDII). A retrospective, observational study in 112 patients with diabetes mellitus treated with CSII from 2005 to 2012, previously treated with MDII and receiving individualized diabetic education with a specific protocol. Variables analyzed included: prevalence of the different indications of pump treatment; mean annual HbA1c and fructosamine values before and after CSII treatment; and hypoglycemia frequency and symptoms. The most common reason for pump treatment was brittle diabetes (74.1%), followed by frequent or severe hypoglycemia or hypoglycemia unawareness (44.6%). Other indications were irregular food intake times for professional reasons (20.2%), dawn phenomenon (15.7%), pregnancy (12.3%), requirement of very low insulin doses (8.9%), and gestational diabetes (0.9%). HbA1c decreased by between 0.6% and 0.9%, and fructosamine by between 5.1% and 12.26%. Nine percent of patients experienced hypoglycemia weekly, 24% every two weeks, and 48% monthly. No hypoglycemia occurred in 19% of patients. Only 10% had neuroglycopenic symptoms. Hypoglycemia unawareness was found in 21%. Hypoglycemia was more common at treatment start, and its frequency rapidly decreased thereafter. CSII therapy provides a better glycemic control than MDII treatment. Specific patient training and fine adjustment of insulin infusion doses are required to prevent hypoglycemic episodes, which are the most common complications, mainly at the start of treatment.

    Adoptive transfer of T cells genetically engineered with a chimeric antigen receptor (CAR) has successfully been used to treat both chronic and acute lymphocytic leukemia as well as other hematological cancers. Experimental therapy with CAR-engineered T cells has also shown promising results on solid tumors. The prostate stem cell antigen (PSCA) is a protein expressed on the surface of prostate epithelial cells as well as in primary and metastatic prostate cancer cells and therefore a promising target for immunotherapy of prostate cancer. We developed a third-generation CAR against PSCA including the CD28, OX-40 and CD3 ζ signaling domains. T cells were transduced with a lentivirus encoding the PSCA-CAR and evaluated for cytokine production (paired Student’s t-test), proliferation (paired Student’s t-test), CD107a expression (paired Student’s t-test) and target cell killing in vitro and tumor growth and survival in vivo (Log-rank test comparing Kaplan-Meier survival curves). PSCA-CAR T cells exhibit specific interferon (IFN)-γ and interleukin (IL)-2 secretion and specific proliferation in response to PSCA-expressing target cells. Furthermore, the PSCA-CAR-engineered T cells efficiently kill PSCA-expressing tumor cells in vitro and systemic treatment with PSCA-CAR-engineered T cells significantly delays subcutaneous tumor growth and prolongs survival of mice. Our data confirms that PSCA-CAR T cells may be developed for treatment of prostate cancer

    Treatment of type 2 diabetes (T2DM) with pioglitazone changes abdominal fat in the opposite direction as treatment with glipizide. To determine whether these two medications affect adipose tissue meal fatty acid storage differently we studied 19 T2DM treated with either pioglitazone (n = 8) or glipizide (n = 11) and 11 non-DM control subjects matched for age, BMI, abdominal and leg fat. A breakfast mixed meal containing [1-(14)C]triolein was given and abdominal and femoral subcutaneous (sc) adipose tissue biopsies were collected 6 and 24 h later to measure meal fatty acid storage. The portion of meal fatty acids stored in upper body sc and lower body sc adipose tissue did not differ between non-DM and T2DM subjects either at 6 or 24 h. Likewise, meal fatty acid storage did not differ between the T2DM participants treated with pioglitazone or glipizide. We conclude that meal fatty acid storage in upper body and lower body sc adipose tissue is not abnormal in T2DM patients treated with pioglitazone or glipizide.

    Phaeohyphomycosis can be caused by a number of different species, being the most common Alternaria alternata and Alternaria infectoria. The biggest risk factor for the development of the infection is immunosuppression. We present the case of a 64-year-old male renal transplant patient who came to hospital for presenting a tumour in the Achilles region which had been gradually growing in size. A skin biopsy was taken for histological study and culture of fungi and mycobacteria. Blood tests and imaging studies were performed. Histopathology study and cultures identified A. infectoria as the causal agent. Imaging studies ruled out internal foci of infection. The lesion was surgically removed with no signs of recurrence after 24 months of follow-up. There are no treatment guidelines at present for cutaneous and subcutaneous Alternaria spp. infections. Various systemic antifungals have been used, either in combination with surgical removal or alone, with varying results. Surgery alone could be useful in the treatment of solitary, localised lesions in transplant patients in whom there are difficulties in controlling immunosuppression.

    Neonatal diabetes mellitus (NDM) is defined as hyperglycemia and impaired insulin secretion with onset within 6 months of birth. While rare, NDM presents complex challenges regarding the management of glycemic control. The availability of continuous subcutaneous insulin infusion pumps (CSII) in combination with continuous glucose monitoring systems (CGM) provides an opportunity to monitor glucose levels more closely and deliver insulin more safely. We report four cases of young infants with NDM successfully treated with CSII and CGM. Moreover, in two cases with Kir 6.2 mutation, we describe the use of CSII in switching therapy from insulin to sulfonylurea treatment. Insulin pump requirement for the 4 neonatal diabetes cases was the same regardless of disease pathogenesis and c-peptide levels. No dilution of insulin was needed. The use of an integrated CGM system helped in a more precise control of BG levels with the possibility of several modifications of insulin basal rates. Moreover, as showed in the first two case-reports, when the treatment was switched from insulin to glibenclamide, according to identification of Kir 6.2 mutation and diagnosis of NPDM, the CSII therapy demonstrated to be helpful in allowing gradual insulin suspension and progressive introduction of sulfonylurea. During the neonatal period, the use of CSII therapy is safe, more physiological, accurate and easier for the insulin administration management. Furthermore, CSII therapy is safe during the switch of therapy from insulin to glibenclamide for infants with permanent neonatal diabetes mellitus.

The T-cell costimulation modulator abatacept is the first biologic therapy for RA to be available in both subcutaneous (SC and intravenous (IV formulations. This review evaluates the utility of SC abatacept, with a particular focus on patient-reported outcomes, including physical function, pain, fatigue, and quality of life. Practical questions relating to the clinical use of SC abatacept are also addressed, including the relevance of abatacept's mechanism of action; whether IV and SC abatacept are comparable; if patients can easily switch from IV to SC abatacept; whether an IV loading dose is needed; and if temporary treatment interruptions or lack of concomitant methotrexate can affect efficacy or safety. Topics that are of particular concern to patients when using SC biologics, such as injection-site reactions, are also discussed. Observational data from registries and meta-analyses of clinical studies suggest comparable clinical efficacy between biologic disease-modifying antirheumatic drugs; however, such analyses rarely focus on key determinants of patient quality of life such as pain, fatigue, and physical function. The head-to-head AMPLE study is one of the first studies powered to directly compare two biologics in patients with RA. Patient-reported outcomes from year 1 of the ongoing study are evaluated, demonstrating comparable improvements in physical function, pain, fatigue, Short Form-36 Health Survey, and Routine Assessment of Patient Index Data 3 scores between SC abatacept and SC adalimumab when administered with

    The aim of this study was to assess pain associated with subcutaneous injection into the abdomen and thigh of different combinations of injection speeds and volumes. The study was a single-centre, one-visit, double-blinded, randomized controlled trial in 82 adults with type 1 or type 2 diabetes receiving daily injections of insulin or glucagon-like peptide-1 (GLP-1) agonists. Participants received 17 subcutaneous injections (12 in abdomen, 5 in thigh) of saline at different injection speeds (150, 300 and 450 µl/s), with different volumes (400, 800, 1200 and 1600 µl), and two needle insertions without any injection. Pain was evaluated on a 100-mm visual analogue scale (VAS) (0 mm no pain, 100 mm worst pain) and on a yes/no scale for pain acceptability. Injection speed had no impact on injection pain (p = 0.833). Injection of larger volumes caused significantly more pain [VAS least square mean differences 1600 vs. 400 µl, 7 · 2 mm (95% confidence interval - CI; 4.6-9.7; p technique to reduce their injection pain.

We aimed a real-life study at evaluating the compliance to SLIT and to SCIT administered by a short-course of four injections during a 3-year period of observation. A group of 145 patients (79 males, 66 females, age ranging from 14 to 69 years), suffering from pollen-induced rhino-conjunctivitis with or without asthma, were included in the study. Following adequate education on AIT and according to patient's preference, 72 patients chose to be treated with short-course SCIT and 73 chose to be treated with SLIT. The latter was performed by allergen extracts from different manufacturers according to the suggested schedules. The rate of withdrawal was as follows: after one year, 15.6% for SCIT and 33.4 for SLIT; after two years, 25.6% for SCIT and 44.8% for SLIT; after three years, 26.7 for SCIT and 46% for SLIT. There was no significant difference in the rate of withdrawal between males and females. Regarding the safety, no systemic reaction requiring medical treatment was observed either in SCIT or SLIT group. The findings of this study confirm that involving the patient in the choice of the route of administration is associated to a satisfactory compliance to AIT. In particular, more than 70% of patients treated with a short schedule of SCIT completed the three-years course of treatment that is recommended for AIT, while this goal was reached by 54% of SLIT treated patients.

    Intravenous rituximab is the standard of care in B-cell non-Hodgkin lymphoma, and is administered over 1·5-6 h. A subcutaneous formulation could reduce patients' treatment burden and improve resource utilisation in health care. We aimed to show the pharmacokinetic non-inferiority of subcutaneous rituximab to intravenous rituximab in follicular lymphoma and to provide efficacy and safety data. SABRINA is a two-stage, randomised, open-label phase 3 study at 113 centres in 30 countries. Eligible patients were aged 18 years or older and had histologically confirmed, previously untreated, CD20-positive grade 1, 2, or 3a follicular lymphoma; Eastern Co-operative Oncology Group performance statuses of 0-2; bidimensionally measurable disease (by CT or MRI); life expectancy of 6 months or more; adequate haematological function for 28 days or more; and one or more symptoms requiring treatment according to the Groupe d'Etudes des Lymphomes Folliculaires criteria. Patients were randomly assigned (1:1) by investigators or members of the research team via a dynamic randomisation algorithm to 375 mg/m 2 intravenous rituximab or 1400 mg subcutaneous rituximab, plus chemotherapy (six-to-eight cycles of cyclophosphamide, doxorubicin, vincristine, and prednisone [CHOP] or eight cycles of cyclophosphamide, vincristine, and prednisone [CVP]), every 3 weeks during induction, then rituximab maintenance every 8 weeks. Randomisation was stratified by selected chemotherapy, Follicular Lymphoma International Prognostic Index, and region. The primary endpoint for stage 2 was overall response (ie, confirmed complete response, unconfirmed complete response, and partial response) at the end of induction. Efficacy analyses were done in the intention-to-treat population. Pooled data from stages 1 and 2 are reported on the basis of the clinical cutoff date of the last patient completing the maintenance phase of the study.

    Radioprotective effects were investigated in mice which received subcutaneously a single dose of each inorganic metal: Co, Cu, Rb, Sr, Mo and W 24 hours post irradiation of 60 Co γ-rays with a sublethal dose. The effects were observed in mice injected with Co at an optimum dosage of 20 mg/kg·body weight. Then to elucidate mechanisms of the effects, mice were injected with Co containing the radioactive tracer ( 60 Co) following the radiation exposure, measured elimination of the radioactivity for 7 days, then sacrificed and divided to some tissues and organs. The radioactivity in whole body during this period resulted in a markedly higher retention than that for mice injected with [ 60 Co] alone, as well as liver in the organs. These higher retentions appeared to be related to the radioprotective effects. (author)

    Full Text Available Background: There is a felt need for trying newer therapeutic modalities in patients with chronic spontaneous urticaria, especially in the subset of patients classified as non-responders to antihistamines. Autologous serum therapy is an upcoming modality of treatment, and we decided to study its efficacy by subcutaneous route. Aims: To evaluate the effectiveness of subcutaneous autologous serum therapy (AST in CSU. Methods: This was a single blind, placebo-controlled parallel group, randomized, controlled study. Twenty-four patients with CSU (11M: 13 F were given subcutaneous AST and seventeen patients (7 M: 10F patients were given subcutaneous injection normal saline (placebo, along with levocetirizine in an on-demand basis in both groups. Results: Urticaria activity score (UAS came down from 35.74 to 7 at the end of 9 weeks and the patients' requirement of antihistamines also reduced remarkably from 5.8 to 1.7 per week in the serum group. Sub-cutaneous saline group did not show statistically significant fall in UAS. Saline group showed UAS 32.8 at zero week to 22.1 at the end of 9 weeks. DLQI showed significant fall in serum group, from 14.26 to 4 at the end of 9 weeks. Conclusion: Subcutaneous autoserum therapy is effective in treatment of CSU.

    Full Text Available Advanced stage of Parkinson's disease is associated with motor complications: motor fluctuations and dyskinesias. The disease can no longer be satisfactorily treated with oral therapy that is based on treatment with levodopa. Dying of dopamine neurons, a short half-life of levodopa and pulsatile stimulation of dopamine receptors are the main reasons for these complications. Currently, there are three options available to treat the advanced stage of Parkinson's disease: subcutaneous infusion of apomorphine, intrajejunal infusion of levodopa and deep brain stimulation. It is necessary to choose the optimal method of treatment that is most suitable for the individual patient.

    Subcutaneous immunoglobulin (SCIG) is effective as maintenance treatment in chronic inflammatory demyelinating polyneuropathy (CIDP). We investigated whether multiple subcutaneous infusions are as effective as conventional therapy with intravenous loading doses in treatment-naive patients with CIDP. Twenty patients fulfilling the clinical and electrophysiological criteria for CIDP were included and treated with either SCIG (0.4 g/kg/week) for 5 weeks or intravenous immunoglobulin (IVIG) (0.4 g/kg/day) for 5 days. After 10 weeks, patients were switched to the opposite treatment arm and followed for a further 10 weeks. All participants were evaluated at weeks 0, 2, 5 and 10 during both therapies. Primary outcome was combined isokinetic muscle strength (cIKS). Secondary outcomes were disability, clinical evaluation of muscle strength and the performance of various function tests. All participants received both therapies, 14 completing the protocol. Overall, cIKS increased by 7.4 ± 14.5% (P = 0.0003) during SCIG and by 6.9 ± 16.8% (P = 0.002) during IVIG, the effect being similar (P = 0.80). Improvement of cIKS peaked 2 weeks after IVIG and 5 weeks after SCIG. Disability improved during SCIG treatment only. Muscle strength determined by manual muscle testing improved after 5 and 10 weeks during SCIG but only after 5 weeks during IVIG. The remaining parameters improved equally during both treatments. Plasma immunoglobulin G levels at baseline and improvement of cIKS were related. In treatment-naive patients with CIDP, short-lasting SCIG and IVIG therapy improve motor performance to a similar degree, but with earlier maximal improvement following IVIG than SCIG treatment. © 2016 EAN.

    To demonstrate the pharmacokinetic/pharmacodynamic (PK/PD) equivalence of a biosimilar enoxaparin to the reference drug, and to assess its safety and tolerability in healthy volunteers. A randomized, double-blind, crossover, 2-sequence, single-dose study was conducted in healthy volunteers of both sexes. Participants were sequentially and randomly administered single subcutaneous injections of enoxaparin 100 mg manufactured by Rovi (test; Madrid, Spain) and Clexane ® (enoxaparin 100 mg manufactured by Sanofi, reference) separated by a 1-week washout period. The primary PK/PD variables were maximum activity (A max ) and area under the effect curve from time 0 to the last measured activity (T) (AUEC 0-T ) and AUEC from time 0 to infinity (AUEC 0-inf ) of anti-FXa activity, and A max and AUEC 0-T of anti-FIIa activity. Secondary variables were A max and AUEC 0-T , AUEC 0-inf of tissue factor pathway inhibitor, and the ratio of AUEC 0-T anti-FXa to anti-FIIa activity. Biosimilarity would be shown when the 95% CI of the ratio of geometric least squares means (95% CI RGLSMs) of primary PK/PD parameters fell within the standard range of bioequivalence, ie, 80%-125%. The study sample consisted of 46 volunteers (33 males) aged 18-44 years and with body mass index ranging from 19.0 to 31.1 kg/m 2 . Three subjects did not complete the study. The curves of anti-FXa, anti-FIIa and tissue factor pathway inhibitor activities corresponding to administration of the test and reference products were comparable. The 95% CI RGLSMs of A max , AUEC 0-T and AUEC 0-inf for anti-FXa activity were 94.6%-105.9%, 99.8%-108.0% and 100.0%-108.6% respectively; A max and AUEC 0-T for anti-FIIa activity were 94.7%-112.6% and 90.9%-117.9% respectively. In addition, the 95% CI RGLSMs of all secondary variables fell within the range 80%-125%. The incidence and types of adverse events after administration of the test and reference drugs were similar. The results conclusively showed that the enoxaparin

Subjects and methods: A randomized, double-blind, two-sequence, crossover study was conducted. Subjects were randomly assigned to receive a single dose, that is, 4,000 IU, of the test or comparator epoetin alfa. After 4 weeks, all subjects received the alternative formulation. The primary PK parameters, maximum observed concentration (Cmax and area under the curve extrapolated to infinity (AUCinf, were calculated with the serum erythropoietin (EPO concentrations from blood samples collected for 144 h after dosing. The reticulocyte, hematocrit, hemoglobin and red blood cell counts were measured up to 312 h as PD markers. The primary PD parameters, maximum observed effect (Emax and area under the effect curve (AUEC, were obtained from the baseline-corrected reticulocyte count. The serum EPO concentration and the reticulocyte count were used to assess the concentration–response relationship. The tolerability and immunogenicity profiles were assessed together. Results: Forty-two subjects completed the study. The mean EPO concentration–time profiles were comparable between the two formulations. The geometric mean ratios (90% CI of the Cmax and AUCinf were 0.908 (0.843–0.978 and 1.049 (0.999–1.101, respectively, both of which were within the regulatory range of 0.80–1.25.

    In this study, we aim to determine the in vivo effect of human umbilical cord blood-derived multipotent stem cells (hUCB-MSCs) on neuropathic pain, using three, principal peripheral neuropathic pain models. Four weeks after hUCB-MSC transplantation, we observed significant antinociceptive effect in hUCB-MSC-transplanted rats compared to that in the vehicle-treated control. Spinal cord cells positive for c-fos, CGRP, p-ERK, p-p 38, MMP-9 and MMP 2 were significantly decreased in only CCI model of hUCB-MSCs-grafted rats, while spinal cord cells positive for CGRP, p-ERK and MMP-2 significantly decreased in SNL model of hUCB-MSCs-grafted rats and spinal cord cells positive for CGRP and MMP-2 significantly decreased in SNI model of hUCB-MSCs-grafted rats, compared to the control 4 weeks or 8weeks after transplantation (ppain signaling during pain signal processing within the nervous system, especially for CCI model. Thus, subcutaneous administration of hUCB-MSCs might be beneficial for improving those patients suffering from neuropathic pain by decreasing neuropathic pain activation factors, while increasing neuropathic pain inhibition factor.

    A 6-mg dose of SC sumatriptan is the most efficacious and fast-acting acute treatment for migraine, but a 3-mg dose of SC sumatriptan may improve tolerability while maintaining efficacy. This randomized, double-blind, crossover study compared the efficacy and tolerability of 3 mg subcutaneous (SC) sumatriptan (DFN-11) with 6 mg SC sumatriptan in 20 adults with rapidly-escalating migraine attacks. Eligible subjects were randomized (1:1) to treat 1 attack with DFN-11 and matching placebo autoinjector consecutively or 2 DFN-11 autoinjectors consecutively and a second attack similarly but with the alternative dose (3 mg or 6 mg). The proportions of subjects who were pain-free at 60 min postdose, the primary endpoint, were similar following treatment with 3 mg SC sumatriptan and 6 mg SC sumatriptan (50% vs 52.6%, P  =  .87). The proportions of subjects experiencing pain relief (P  ≥  .48); reductions in migraine pain intensity (P  ≥  .78); and relief from nausea, photophobia, or phonophobia (P  ≥  .88) with 3 mg SC sumatriptan and 6 mg SC sumatriptan were similar, as were the mean scores for satisfaction with treatment (M  =  2.6 vs M  =  2.4, P  =  .81) and the mean number of rescue medications used (M  =  .11 vs M  =  .26, P  =  .32). The most common adverse events with the 3- and 6-mg doses were triptan sensations - paresthesia, neck pain, flushing, and involuntary muscle contractions of the neck - and the incidence of adverse events with both doses was similar (32 events total: 3 mg, n  =  14 [44%]; 6 mg, n  =  18 [56%], P  =  .60). Triptan sensations affected 4 subjects with the 6-mg dose only, 1 subject with the 3-mg dose only, and 7 subjects with both sumatriptan doses. Chest pain affected 2 subjects (10%) treated with the 6-mg dose and no subjects (0%) treated with the 3-mg dose of DFN-11. There were no serious adverse events. The 3-mg SC dose

    Multiple sclerosis (MS) currently requires long-term treatment with disease-modifying drugs, administered parenterally up to once daily. The need for regular self-injection can be a barrier to treatment for many patients. Autoinjectors can help patients overcome problems or concerns with self-injection and could, therefore, improve treatment adherence. This study was performed to assess the suitability of a new electronic device for the subcutaneous (sc) administration of interferon (IFN) beta-1a, 44 mcg three times weekly, for relapsing MS. In this Phase IIIb, multicentre, single-arm study, patients with relapsing MS who had been consistently self-injecting sc IFN beta-1a using an autoinjector for at least 6 weeks were taught to use the new device and self-administered treatment for 12 weeks thereafter. Patient-rated suitability of the device was assessed at the end of Week 12 using the Patient User Trial Questionnaire. Patient satisfaction with, and evaluation of, the injection process was assessed using the MS Treatment Concern Questionnaire. Trainers evaluated the device using the Trainer User Trial Questionnaire. At Week 12, 71.6% (73/102) of patients considered the device 'very suitable' or 'suitable' for self-injection; 92.2% (94/102) reported some degree of suitability and only 7.8% (8/102) found the device 'not at all suitable'. At Weeks 4, 8 and 12, most patients reported that injection preparation and clean-up, performing injections and ease of device use in the previous 4 weeks compared favourably with, or was equivalent to, their previous experience of self-injection. Injection-related pain, injection reactions and 'flu-like' symptoms remained stable over the 12 weeks. Each device feature was rated 'very useful' or 'useful' by at least 80% of patients. All trainers and 95.2% (99/104) of patients found device functions 'very easy' or 'easy' to use. Overall convenience was considered the most important benefit of the device.

    We performed a subanalysis of cancer patients enrolled in a clinical trial that compared long-term (6 months) treatment with a low-molecular-weight heparin (LMWH) administered subcutaneously or with acenocoumarol. The subanalysis assessed whether the characteristics of the tumor had an influence on the clinical response. A randomized open trial included 69 patients with cancer and symptomatic proximal deep vein thrombosis of the lower limbs. The tumor characteristics and treatment type were recorded. The main assessment criterion was the 12-month incidence of recurrent symptomatic venous thromboembolism (VTE). Sixty-one patients (88.4%) were analyzed. At the time of inclusion, the cancer characteristics and treatment were comparable between the 2 groups. Over the course of 12 months, the recurrent VTE was significantly greater in the elderly patients (71.5 ± 6.4 vs. 62.0 ± 15.1; p=.006). The logistic regression analysis showed no association between VTE recurrence and the location or extent of the tumor. However, the use of thrombogenic chemotherapy (p=.045) was independently associated with VTE recurrence, and longterm treatment with tinzaparin was almost a protective factor (p=.15). In this small sample, we observed an association between thrombogenic chemotherapy and recurrent VTE. The tendency towards a reduction in VTE recurrence at 12 months in patients with cancer in the LMWH group could be attributed to the effect of the full LMWH dosage.

    To evaluate the influence of the treatment with continuous subcutaneous insulin infusion on the quality of life of type 1 diabetics. An analytical study of cohorts was conducted on 80 patients diagnosed with type 1 diabetes mellitus, with more than five years of evolution and without evidence of micro-macro vascular complications, on treatment with CSII or multiple daily insulin injections (MDII). The quality of life of both groups was evaluated by means of a validated modification of the survey "Diabetes Quality of Life Measure" (DQLM). The SPSS 11.0 software was used to determine Chi(2) and establish statistically significant values for a Pquality of life than the patients with multiple daily insulin injections, although only in 16% (6/36) of the questions, were the scores significantly better in the first group. There were no significant differences in the dimensions studied between both groups, but the patients with CSII obtain better results in many variables of the fe DQLM, and they were more satisfied with the flexibility that their treatment offers them in daily life activities.

    2015-01-01

    Full Text Available Introduction. Platelet-rich plasma (PRP is a product widely used in sports medicine, tissue repair, and general surgery. A recent meta-analysis showed this product to be beneficial when introduced into a wound area, be it intra-articular (i.e., joint-injections or direct introduction onto the wound surface. Methods. Between the years of 2012 and 2014 a questionnaire evaluating surgical outcome after port (venous access device removal was answered by 100 patients in the control group and 20 patients in a PRP group, leading to a total of 120 patients in this single center, retrospective, subjective outcome evaluation. Results. No statistical difference was shown in postsurgical complication rates, postsurgical pain, decreased mobility, and overall quality of life. A significant difference was shown in overall patient satisfaction and the desire to further improve port area scarring. Results differed significantly in favor of the PRP group. Interestingly, approximately 40.2% of patients are dissatisfied with the surgical outcome after port removal in the control group. This result, though surprising, may be improved to 10% dissatisfaction when a PRP product is used. Conclusion. PRP products such as Arthrex ACP are safe to use and present an additional option in improving surgical outcome.

Objective: This study is a literature review of the research related to the safety, efficacy, and patient acceptability of subcutaneous methotrexate for its application in the treatment of severe recalcitrant psoriasis. Methods: Systematic literature searches were conducted of the PubMed, Ovid, and ClinicalTrials.gov databases. Results: Only three relevant sources of literature were found studying subcutaneous methotrexate specifically in the context of psoriasis. Of these, only one clinical trial was found to directly study the use of subcutaneous methotrexate in psoriasis patients; however, results of this study have not been published. The other two literature sources involved a cost-effectiveness analysis and a literature review for subcutaneous methotrexate. Otrexup™ and Rasuvo™ are two particular single-use auto-injector modalities of subcutaneous methotrexate that are approved by the US Food and Drug Administration. The equivalents of Rasuvo available in countries outside of the USA are advertised as Metoject® or Metex®. Much more research has been conducted on the use of subcutaneous methotrexate in rheumatoid arthritis patients. Conclusion: There is a lack of original evidence-based studies evaluating the use of subcutaneous methotrexate specifically for the treatment of psoriasis. Based on the more extensively researched data on the safety, efficacy, and patient acceptability of subcutaneous methotrexate in rheumatoid arthritis patients

  10. Preclinical Development of a Subcutaneous ALAS1 RNAi Therapeutic for Treatment of Hepatic Porphyrias Using Circulating RNA Quantification

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The acute hepatic porphyrias are caused by inherited enzymatic deficiencies in the heme biosynthesis pathway. Induction of the first enzyme 5-aminolevulinic acid synthase 1 (ALAS1 by triggers such as fasting or drug exposure can lead to accumulation of neurotoxic heme intermediates that cause disease symptoms. We have demonstrated that hepatic ALAS1 silencing using siRNA in a lipid nanoparticle effectively prevents and treats induced attacks in a mouse model of acute intermittent porphyria. Herein, we report the development of ALN-AS1, an investigational GalNAc-conjugated RNAi therapeutic targeting ALAS1. One challenge in advancing ALN-AS1 to patients is the inability to detect liver ALAS1 mRNA in the absence of liver biopsies. We here describe a less invasive circulating extracellular RNA detection assay to monitor RNAi drug activity in serum and urine. A striking correlation in ALAS1 mRNA was observed across liver, serum, and urine in both rodents and nonhuman primates (NHPs following treatment with ALN-AS1. Moreover, in donor-matched human urine and serum, we demonstrate a notable correspondence in ALAS1 levels, minimal interday assay variability, low interpatient variability from serial sample collections, and the ability to distinguish between healthy volunteers and porphyria patients with induced ALAS1 levels. The collective data highlight the potential utility of this assay in the clinical development of ALN-AS1, and in broadening our understanding of acute hepatic porphyrias disease pathophysiology.

    To investigate the serial changes of tumor hypoxia in response to single high-dose irradiation by various clinical and preclinical methods to propose an optimal fractionation schedule for stereotactic ablative radiation therapy. Syngeneic Lewis lung carcinomas were grown either orthotopically or subcutaneously in C57BL/6 mice and irradiated with a single dose of 15 Gy to mimic stereotactic ablative radiation therapy used in the clinic. Serial [(18)F]-misonidazole (F-MISO) positron emission tomography (PET) imaging, pimonidazole fluorescence-activated cell sorting analyses, hypoxia-responsive element-driven bioluminescence, and Hoechst 33342 perfusion were performed before irradiation (day -1), at 6 hours (day 0), and 2 (day 2) and 6 (day 6) days after irradiation for both subcutaneous and orthotopic lung tumors. For F-MISO, the tumor/brain ratio was analyzed. Hypoxic signals were too low to quantitate for orthotopic tumors using F-MISO PET or hypoxia-responsive element-driven bioluminescence imaging. In subcutaneous tumors, the maximum tumor/brain ratio was 2.87 ± 0.483 at day -1, 1.67 ± 0.116 at day 0, 2.92 ± 0.334 at day 2, and 2.13 ± 0.385 at day 6, indicating that tumor hypoxia was decreased immediately after irradiation and had returned to the pretreatment levels at day 2, followed by a slight decrease by day 6 after radiation. Pimonidazole analysis also revealed similar patterns. Using Hoechst 33342 vascular perfusion dye, CD31, and cleaved caspase 3 co-immunostaining, we found a rapid and transient vascular collapse, which might have resulted in poor intratumor perfusion of F-MISO PET tracer or pimonidazole delivered at day 0, leading to decreased hypoxic signals at day 0 by PET or pimonidazole analyses. We found tumor hypoxia levels decreased immediately after delivery of a single dose of 15 Gy and had returned to the pretreatment levels 2 days after irradiation and had decreased slightly by day 6. Our results indicate that single

    This systematic review aimed to examine the evidence for teriparatide in Asia for osteoporosis with a high fracture risk and for exploratory (unapproved) bone-related indications. MEDLINE (1946+), EMBASE (1966+), and ClinicalTrials.gov (2008+) were searched (16 August 2013); all studies of daily subcutaneous teriparatide 20 μg for bone-related conditions from China, Hong Kong, Japan, Republic of Korea, Philippines, Singapore, and Taiwan were included. Evidence on efficacy/safety was retrieved primarily from randomized controlled trials (10 publications) of postmenopausal women from Japan and China. In these studies, teriparatide was well tolerated; subjects had significantly greater increases in lumbar spine bone mineral density (BMD) from baseline compared with placebo, antiresorptive agents, or elcatonin/calcitonin; bone turnover markers increased from baseline and were sustained at elevated levels during teriparatide treatment. Few studies reported fracture risk, pain, or quality of life; one study showed a lower incidence of new-onset vertebral fracture with teriparatide versus antiresorptive agents. Nonrandomized studies (nine publications, one unpublished trial) conducted mainly in Taiwan, Japan, and the Republic of Korea provided supporting data for efficacy. The exploratory (unapproved) use of teriparatide (17 publications) for fracture healing and osteonecrosis of the jaw was described primarily in case reports. The clinical effectiveness of teriparatide for treatment of postmenopausal women with osteoporosis who are at high risk of fracture in Asia is focused primarily on improvements in BMD and tolerability. Recommended additional studies may include assessment of fracture risk and the effect of teriparatide on pain, quality of life, and mortality in Asia.

    There are four efficacious subcutaneous anti-tumor necrosis factor alpha (TNF-alpha) agents used for the therapy of ankylosing spondilitis (AS), but apparently little or no differences in their effectiveness was proven. By this study, we aimed to compare Assessment in Ankylosing Spondylitis Response Criteria 20 response patterns (ASAS20) between subcutaneous approved biological agents in patients affected by ankylosing spondylitis by means of a mixed treatment comparison of different randomized controlled trials (RCTs) on the efficacy of biological therapies. A search in scientific literature was performed to identify the most complete collection of RCTs available on the selected topic. Similarly designed double-blind, randomized, placebo-controlled trials investigating the efficacy of the subcutaneous and approved TNF-alpha inhibitors such as etanercept, certolizumab pegol, golimumab and adalimumab in the treatment of ankylosing spondylitis patients were identified. The endpoint of interest was ASAS20 response criterium at 12 weeks. Results were analysed simultaneously using Bayesian mixed treatment comparison techniques. Results were expressed as odds ratio (OR) of positive ASAS20 response and associated 95 % credible intervals (CrIs). The probability of being the best treatment was also reported. Only five RCTs matched the inclusion criteria for consequent data extraction and analysis. Mixed treatment comparison of data from such RCTs demonstrated that all subcutaneous anti-TNF-alpha agents are more effective in inducing an ASAS20 response than placebo. Data from 24 weeks' follow-up were not taken into account as early escape granted in some of the studies made results at 24 weeks unmatchable. In our analysis, golimumab proved to be the drug that more probably represents the best choice for achieving ASAS20 response at 12 weeks, although no differences were observed when comparing directly every single subcutaneous anti-TNF-alpha agent against another.

    To observe the five-year efficacy of standardised specific subcutaneous immunotherapy for house dust mite allergy in monosensitised and polysensitised children with persistent allergic rhinitis. From January 2007 to August 2009, 236 children with persistent allergic rhinitis were divided into 2 groups: 1 group received standardised specific subcutaneous immunotherapy using house dust mite extract; the other received pharmacotherapy with intranasal corticosteroids and oral antihistamines. A total of 193 patients (106 in the immunotherapy group and 87 in the pharmacotherapy group) completed treatment. Scores for symptoms, total medication and quality of life were evaluated. The subcutaneous immunotherapy group demonstrated a significant reduction in visual analogue scale scores, Rhinoconjunctivitis Quality of Life Questionnaire scores and total medication scores (p 0.05). No serious adverse events occurred. Standardised subcutaneous immunotherapy has long-term efficacy for children with persistent allergic rhinitis. Single-allergen subcutaneous immunotherapy was appropriate for allergic rhinitis caused by multiple allergens, including house dust mites, in the paediatric population.

    To compare continuous subcutaneous insulin infusion therapy (CSII) with multiple daily insulin therapy (MDI) on metabolic control in children and adolescents with type 1 diabetes mellitus (T1DM) over the long term. 52 T1DM patients treated with CSII and monitored for at least 1 year prior to and at least five years following CSII were included. 38 age and sex-matched MDI controls with a 5-year follow up were recruited. Mean age of the subjects, duration of diabetes and CSII therapy were 17.0±4.8 years, 10.7±2.8 years and 7.7±1.5 years respectively. Mean HbA1c in the year prior to CSII, during the first year of treatment and after 5 years of CSII were 7.3±1% (56 mmol/mol), 7.0±0.7% (53 mmol/mol) and 7.8±1.3% (62 mmol/mol) respectively. Initial and 5-year mean HbA1C levels of controls were 7.9±1.08% and 8.6±1.8%. Mean HbA1c values were significantly lower in those receiving CSII therapy throughout follow-up. Basal and total insulin doses were significantly lower in the CSII group at all times. HbA1c was compared between subjects by age (0-5, 6-11 and 12-18 years) with no significant difference between them. Although CSII mean HbA1c values exceeded accepted good metabolic control limits after 5 years, CSII produces better HbA1c control at all times and in all age groups compared to MDI.

This is a retrospective cohort study with following up during the first 12 months that CSII group (n=30) begins the use of "bolus wizard" and the MDI-calculator (n=30) group begins the use of the bolus calculator (Accu-Chek(®) Aviva Expert). HbA1c (3, 6 and 12 months). Questionnaires used: EsDQOL (quality of life), FH-15 (fear of hypoglycemia), and Clarke (perception of hypoglycemia). T Student and nonparametric tests. The average reduction in HbA1c during the study was significantly higher in CSII group (-0.56±0.84%) compared with the MDI group (0.097±0.94%), P=.028. The average basal insulin dose was significantly higher in the MDI group (at baseline, 6 and 12 months). No significant differences were found between the 2 treatment groups after analyzing the EsDQOL, FH-15 and Clarke questionnaires. In the CSII group, perceived quality of life assessed by the EsDQOL questionnaire was found to be better at the end of the study than at the beginning of using the insulin pump. The average reduction in HbA1c was significantly higher in the CSII group. In the CSII group, perceived quality of life was better at the end of the study than at the beginning.

    With the understanding of the extensive vascular supply of the subcutaneous tissue, of its efficacy in the protection of the anatomical structures and of its capability of promoting the adequate functioning of very stressed regions of the human body, the use of subcutaneous adipose flaps has become a valid and sometimes the only reasonable therapeutic weapon in the treatment of small and medium-sized tissue loss. Such a defect represents a common complication of great toe injuries and surgery. Here subcutaneous flap reconstruction is proposed for the treatment of dorsal and medial soft tissue losses of the hallux complicated with infection. Two case are reported. To the best of the authors' knowledge, this application has not been reported in this anatomical site so far. The technique might be worth knowing both for orthopedic and plastic surgeons, as it may represent a safe, less invasive solution for most tegumentary problems of the dorso-medial side of the first ray.

    Full Text Available Bronchogenic cysts occur due to the anomalous development of the primitive tracheobronchial tree early in fetal life. They are usually present in middle mediastinum. Rarely, they have been found in other locations. We describe two patients with subcutaneous bronchogenic cysts located over manubrium sterni with special emphasis on the difficulties in pre-operative diagnosis. The two boys were managed by complete excision of the cysts. The children are well on follow-up.

    Purpose Fentanyl sublingual tablets (FST) are a potentially useful alternative to parenteral opioids such as subcutaneous morphine (SCM) to treat severe cancer pain episodes. No direct comparison between FST and SCM is available. The aim of this study was to test noninferiority of FST versus SCM during the first 30 min postadministration. Methods Patients receiving stable opioid therapy and experiencing a severe pain episode were randomly assigned to either 100 µg FST or 5 mg SCM in a double-blind, double-dummy trial. Average pain intensity (PI) assessed on a 0 to 10 numerical rating scale at 10, 20, and 30 min postadministration was the main end point. Analysis of covariance, adjusted by baseline PI, was the main analysis. The noninferiority margin (NIm) for the between-group difference was set at -0.6, that is, equal to one third of the minimum clinically important PI difference of two points. Results A total of 114 patients were randomly assigned to either FST (n = 58) or SCM (n = 56). One patient (in the FST group) withdrew consent before drug administration and was excluded from analysis. Baseline mean PIs were 7.5 in both groups; mean average PIs assessed at 10, 20, and 30 min postadministration were 5.0 and 4.5 for FST and SCM, respectively, with the 95% CI of the between-group difference including the NIm (-0.49; 95% CI, -1.10 to 0.09). Patients taking FST received a second drug dose after 30 min more frequently than did patients taking SCM (51% v 37%, respectively; risk difference, -13%; 95% CI, -30% to 3%). Both treatments were well tolerated, with average follow-up adverse event scores below the response of "A Little." Ninety-three percent of patients preferred the sublingual administration. Conclusion This trial did not show noninferiority of FST versus SCM within the chosen NIm. Both treatments were safe, and patients preferred the sublingual route of administration. FST provides analgesia with modest to moderate increased risk of lower efficacy

    Approximately two-thirds of patients with chronic inflammatory demyelinating polyneuropathy (CIDP) need long-term intravenous immunoglobulin. Subcutaneous immunoglobulin (SCIg) is an alternative option for immunoglobulin delivery, but has not previously been investigated in a large trial of CIDP. The PATH study compared relapse rates in patients given SCIg versus placebo. Between March 12, 2012, and Sept 20, 2016, we studied patients from 69 neuromuscular centres in North America, Europe, Israel, Australia, and Japan. Adults with definite or probable CIDP who responded to intravenous immunoglobulin treatment were eligible. We randomly allocated participants to 0·2 g/kg or 0·4 g/kg of a 20% SCIg solution (IgPro20) weekly versus placebo (2% human albumin solution) for maintenance treatment for 24 weeks. We did randomisation in a 1:1:1 ratio with an interactive voice and web response system with a block size of six, stratified by region (Japan or non-Japan). The primary outcome was the proportion of patients with a CIDP relapse or who were withdrawn for any other reason during 24 weeks of treatment. Patients, caregivers, and study personnel, including those assessing outcomes, were masked to treatment assignment. Analyses were done in the intention-to-treat and per-protocol sets. This trial is registered with ClinicalTrials.gov, number NCT01545076. In this randomised, double-blind, placebo-controlled trial, we randomly allocated 172 patients: 57 (33%) to the placebo group, 57 (33%) to the low-dose group, and 58 (34%) to the high-dose group. In the intention-to-treat set, 36 (63% [95% CI 50-74]) patients on placebo, 22 (39% [27-52]) on low-dose SCIg, and 19 (33% [22-46]) on high-dose SCIg had a relapse or were withdrawn from the study for other reasons (p=0·0007). Absolute risk reductions were 25% (95% CI 6-41) for low-dose versus placebo (p=0·007), 30% (12-46) for high-dose versus placebo (p=0·001), and 6% (-11 to 23) for high-dose versus low-dose (p=0·32

    The intra-articular injection of adipose-derived stem cells (ASCs) is a novel potential therapy for patients with osteoarthritis (OA). However, the efficacy of ASCs from different regions of the body remains unknown. This study investigated whether ASCs from subcutaneous or visceral adipose tissue provide the same improvement of OA. Mouse and human subcutaneous and visceral adipose tissue were excised for ASC isolation. Morphology, proliferation, surface markers and adipocyte differentiation of subcutaneous ASCs (S-ASCs) and visceral ASCs (V-ASCs) were analysed. A surgically induced rat model of OA was established, and 4 weeks after the operation, S-ASCs, V-ASCs or phosphate-buffered saline (PBS, control) were injected into the articular cavity. Histology, immunohistochemistry and gene expression analyses were performed 6 weeks after ASC injection. The ability of ASCs to differentiate into chondrocytes was assessed by in vitro chondrogenesis, and the immunosuppressive activity of ASCs was evaluated by co-culturing with macrophages. The proliferation of V-ASCs was significantly greater than that of S-ASCs, but S-ASCs had the greater adipogenic capacity than V-ASCs. In addition, the infracted cartilage treated with S-ASCs showed significantly greater improvement than cartilage treated with PBS or V-ASCs. Moreover, S-ASCs showed better chondrogenic potential and immunosuppression in vitro. Subcutaneous adipose tissue is an effective cell source for cell therapy of OA as it promotes stem cell differentiation into chondrocytes and inhibits immunological reactions. © 2017 The Authors.

    Full Text Available Background: Chronic spontaneous urticaria (CSU has a detrimental effect on patients′ emotional and physical quality of life. Omalizumab, an anti-immunoglobulin E humanized monoclonal antibody, has been shown to be very effective in the treatment of refractory chronic urticaria patients but may not be an economically viable option for all CSU patients. However, we present a case series where a single dose of omalizumab gave sustained relief of symptoms in patients with CSU, which may be an economical option. Aims: The aim of this study is to assess the efficacy of a single dose of omalizumab in the treatment of CSU. Materials and Methods: Four patients of CSU whose disease was not controlled with four times the licensed dose of tablet fexofenadine 180 mg were exhibited one subcutaneous injection of omalizumab and were followed up at 4 weekly intervals for 24 weeks for Weekly Urticaria Activity Score 7 (UAS7 and Dermatology Life Quality Index (DLQI. Results: A sharp decline in UAS7 and DLQI was documented in 7-10 days. The decline was maintained up to 16 weeks in one case and 20 weeks in the other three cases. Both the scores at the end of the follow-up period of 24 weeks were better than the pre-omalizumab scores. Conclusion: The results of this case series indicate the efficacy of a single-dose omalizumab in treating moderate to severe refractory CSU. Further studies are required to identify the minimum frequency of administering omalizumab to effectively control CSU. This would greatly reduce the cost of this novel therapy.

    Full Text Available The developments in the technologies based on the use of autologous adipose tissue attracted attention to minor depots as possible sampling areas. Some of those depots have never been studied in detail. The present study was performed on subcutaneous adipose depots sampled in different areas with the aim of explaining their morphology, particularly as far as regards stem niches. The results demonstrated that three different types of white adipose tissue (WAT can be differentiated on the basis of structural and ultrastructural features: deposit WAT (dWAT, structural WAT (sWAT and fibrous WAT (fWAT. dWAT can be found essentially in large fatty depots in the abdominal area (periumbilical. In the dWAT, cells are tightly packed and linked by a weak net of isolated collagen fibers. Collagenic components are very poor, cells are large and few blood vessels are present. The deep portion appears more fibrous then the superficial one. The microcirculation is formed by thin walled capillaries with rare stem niches. Reinforcement pericyte elements are rarely evident. The sWAT is more stromal; it is located in some areas in the limbs and in the hips. The stroma is fairly well represented, with a good vascularity and adequate staminality. Cells are wrapped by a basket of collagen fibers. The fatty depots of the knees and of the trochanteric areas have quite loose meshes. The fWAT has a noteworthy fibrous component and can be found in areas where a severe mechanic stress occurs. Adipocytes have an individual thick fibrous shell. In conclusion, the present study demonstrates evident differences among subcutaneous WAT deposits, thus suggesting that in regenerative procedures based on autologous adipose tissues the sampling area should not be randomly chosen, but it should be oriented by evidence based evaluations. The structural peculiarities of the sWAT, and particularly of its microcirculation, suggest that it could represent a privileged source for

    To evaluate the feasibility to detect activated brown adipose tissue (BAT) using single-time-point infrared thermography of the supraclavicular skin region under thermoneutral conditions. To this end, infrared thermography was compared with 18-F-FDG PET, the current reference standard for the detection of activated BAT. 120 patients were enrolled in this study. After exclusion of 18 patients, 102 patients (44 female, 58 male, mean age 58±17 years) were included for final analysis. All patients underwent a clinically indicated 18F-FDG-PET/CT examination. Immediately prior to tracer injection skin temperatures of the supraclavicular, presternal and jugular regions were measured using spatially resolved infrared thermography at room temperature. The presence of activated BAT was determined in PET by typical FDG uptake within the supraclavicular adipose tissue compartments. Local thickness of supraclavicular subcutaneous adipose tissue (SCAT) was measured on CT. Measured skin temperatures were statistically correlated with the presence of activated BAT and anthropometric data. Activated BAT was detected in 9 of 102 patients (8.8%). Local skin temperature of the supraclavicular region was significantly higher in individuals with active BAT compared to individuals without active BAT. However, after statistical correction for the influence of BMI, no predictive value of activated BAT on skin temperature of the supraclavicular region could be observed. Supraclavicular skin temperature was significantly negatively correlated with supraclavicular SCAT thickness. We conclude that supraclavicular SCAT thickness influences supraclavicular skin temperature and thus makes a specific detection of activated BAT using single-time-point thermography difficult. Further studies are necessary to evaluate the possibility of BAT detection using alternative thermographic methods, e.g. dynamic thermography or MR-based thermometry taking into account BMI as a confounding factor.

    2009-01-01

    Background and purpose: For treatment of multifocal motor neuropathy (MMN), we hypothesized that (i) infusion of equivalent dosages of subcutaneous immunoglobulin (SCIG) is as effective as intravenous immunoglobulin (IVIG) and that (ii) subcutaneous infusion at home is associated with a better...... at the injection sites for a few weeks. All other adverse effects during SCIG were mild and transient. No differences between treatments of health-related quality of life occurred. Conclusion: In MMN, short-term subcutaneous infusion of immunoglobulin is feasible, safe and as effective as intravenous infusion...

    Purpose: To identify the risk factors for moderate to severe subcutaneous fibrosis after whole neck irradiation. Methods and Materials: We analyzed 233 cases of patients who had undergone whole neck irradiation with 4-MV X-ray or 8-10-MeV electrons, or both, and had been followed with regard to their skin condition for at least 1 year. The prescribed dose to the whole neck ranged from 19.2 to 72.4 Gy (median 50). The skin-absorbed dose was specified as that at a depth of 4.1 mm (d4.1-mm depth ), and a biologically equivalent dose (BED) of d4.1-mm depth was also estimated (BED 1.8 4.1-mm depth ). Results: Univariate analysis revealed that previous neck dissection, concurrent chemotherapy, corticosteroid administration as a part of chemotherapy, fractionation, and BED 1.8 4.1-mm depth were significant prognostic variables. Multivariate analysis showed that BED 1.8 4.1-mm depth and previous neck dissection were the only prognostic variables for moderate to severe subcutaneous fibrosis. Conclusion: A high dose to a 4.1-mm depth of the skin and a history of neck dissection were identified as the predominant risk factors for moderate to severe subcutaneous fibrosis after whole neck irradiation. A subcutaneous dose should be considered in radiotherapy treatment planning involving the whole neck, especially in cases in which patients have undergone previous neck dissection

    Purpose: To report long-term data from a prospective trial of subcutaneous (s.c.) amifostine in patients who received chemoradiotherapy for squamous cell carcinoma of the head and neck (SCCHN). Methods and Materials: Patients ≥18 years of age with previously untreated Stage III/IV SCCHN received fractionated radiotherapy, 1.8-2.0 Gy/day, 5 days per week, to a total dose of 70-72 Gy, plus weekly paclitaxel (40 mg/m 2 ) and carboplatin (100 mg/m 2 ) administered intravenously (i.v.) for 6 weeks. All patients received 500 mg s.c. amifostine 30-60 min before radiotherapy with antihistamine and antiemetic prophylaxis. Results: Twenty patients were evaluable (median age, 55 years). The incidence of Grade 2 xerostomia was 42% and 29% at 12 and 18 months, respectively; there were no reports of Grade ≥3 xerostomia. Grade ≥3 mucositis occurred in 30% of patients, with median time to resolution of 12.5 weeks (range, 5-17 weeks). Survival estimates at 1 and 2 years were 95% and 71%, respectively. All patients experienced Grade 2 weight loss; 7 patients (35%) experienced Grade ≤2 nausea/vomiting. There were no reports of Grade ≥3 amifostine-related adverse events. Conclusions: Subcutaneous amifostine was well tolerated by patients receiving chemoradiotherapy for SCCHN, with lower rates of nausea/vomiting than reported in trials with i.v. amifostine. Xerostomia and mucositis rates were similar to those reported in trials with i.v. amifostine

    The choice between several treatment options for replacing a single missing tooth is influenced by clinical, dentist- and patient-immanent factors. This study aimed to determine the patient factors that would affect the treatment decision to replace a single missing tooth and to assess the satisfaction with several options. 200 volunteers involved (121 females and 79 males) divided into four groups, Group A: consisted of patients with conventional fixed partial dentures or patients with resin bonded fixed partial dentures. Group B: consisted of patients who received removable partial dentures while Group C: consisted of patients who received a single implant supported crown, and a control group D: consisted of patients who received no treatment. Data were collected using a questionnaire. The highest percentage of males within groups (58%) was within the removable prostheses category. The majority of the subjects in the study reported that the main reason for replacing a missing tooth was for esthetic and function. Most important factor affecting the choice between treatment modalities was damaging the neighboring teeth. Pain, post operative sensitivity and dental phobia were important factors in choosing the prosthesis type and affected the control group patients not to have any treatment. The highest satisfaction percentage among groups studied was recorded for dental implants then FPD groups, while the least percentage were in both the control and RPD groups, for all aspects of function, esthetic and speech efficiency. The final choice between FPD, RPD and implant depended on several factors which affected the decision making; among these is cost and patients' awareness of the different treatment options.

    MabThera is an essential component of the standard-of-care regimens in the treatment of non-Hodgkin lymphoma and Chronic Lymphatic Leukemia. MabThera for subcutaneous injection is a novel line extension that has been approved by the European Medicines Agency for the treatment of patients with follicular lymphoma and diffuse large B-cell lymphoma. This study aimed to evaluate in-use stability data of MabThera subcutaneous drug-product solution in single-use syringes for subcutaneous administration according to the European Medicines Agency guideline. The drug-product solution was exposed to material contact surfaces of five different administration setups commonly used in subcutaneous drug delivery. MabThera subcutaneous was transferred under aseptic conditions into polypropylene and polycarbonate syringes and stored for 1, 2, and 4 weeks at 2°C to 8°C followed by 24 hours at 30°C. After storage, subcutaneous administration was simulated and MabThera subcutaneous drug-product solution quality attributes were evaluated by using compendial physico-chemical tests, as well as suitable and validated molecule- and formulation-specific analytical methods. MabThera subcutaneous vials were treated and analyzed in parallel. The physico-chemical results of MabThera subcutaneous in the different setups were comparable to the control for all timepoints. No change in drug-product quality after storage and simulated administration was found compared to the control. However, since single-dose products do not contain preservatives, microbial contamination and growth needs to be avoided and product sterility needs to be ensured. The results showed that MabThera subcutaneous remains compatible and stable, from a physico-chemical perspective, for up to 4 weeks at 2°C to 8°C followed by 24 hours at 30°C with the contact materials tested in this study. In order to avoid and minimize microbial growth, MabThera subcutaneous should be used immediately after removal from the original

  20. Endodontic treatment options after unsuccessful initial root canal treatment: Alternatives to single-tooth implants.

    2016-03-01

    Initial root canal treatment is highly successful, appreciated by patients, and cost-effective, but failures occur. Should a tooth with unsuccessful initial root canal treatment be treated by means of other endodontic procedures or be replaced by a single-tooth implant? Results from systematic reviews of the outcomes of nonsurgical retreatment, apical surgery, replantation, and autotransplantation show high tooth survival rates. Nonsurgical retreatment generally is prioritized before surgical endodontic treatment. Microsurgical endodontic treatment is superior to traditional surgical endodontic treatment and has high survival rates. Intentional replantation remains a viable alternative to extraction. Autotransplantation has a place, particularly in growing patients with an appropriate donor tooth. Single-tooth implants have higher survival rates, but the natural state has intrinsic value. The first-line treatment option after failure of initial root canal treatment is nonsurgical retreatment. Endodontic surgery, intentional replantation, and autotransplantation should be considered before extraction and replacement by a single-tooth implant. Comprehensive case assessment, evaluation of all endodontic options, and risk assessment for caries and periodontal disease are always necessary when choosing the optimal treatment for a patient when initial root canal treatment has failed to heal.

    1998-01-01

    Objective. Granuloma annulare is an uncommon benign inflammatory dermatosis characterized by the formation of dermal papules with a tendency to form rings. There are several clinically distinct forms. The subcutaneous form is the most frequently encountered by radiologists, with the lesion presenting as a superficial mass. There are only a few scattered reports of the imaging appearance of this entity in the literature. We report the radiologic appearance of five cases of subcutaneous granuloma annulare. Design and patients. The radiologic images of five patients (three male, two female) with subcutaneous granuloma annulare were retrospectively studied. Mean patient age was 6.4 years (range, 2-13 years). The lesions occurred in the lower leg (two), foot, forearm, and hand. MR images were available for all lesions, gadolinium-enhanced imaging in three cases, radiographs in four, and bone scintigraphy in one. Results. Radiographs showed unmineralized nodular masses localized to the subcutaneous adipose tissue. The size range, in greatest dimension on imaging studies, was 1-4 cm. MR images show a mass with relatively decreased signal intensity on all pulse sequences, with variable but generally relatively well defined margins. There was extensive diffuse enhancement following gadolinium administration. Conclusion. The radiologic appearance of subcutaneous granuloma annulare is characteristic, typically demonstrating a nodular soft-tissue mass involving the subcutaneous adipose tissue. MR images show a mass with relatively decreased signal intensity on all pulse sequences and variable but generally well defined margins. There is extensive diffuse enhancement following gadolinium administration. Radiographs show a soft-tissue mass or soft-tissue swelling without evidence of bone involvement or mineralization. This radiologic appearance in a young individual is highly suggestive of subcutaneous granuloma annulare. (orig.)

    Purpose. The comparative efficacy of transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) was investigated. Methods. Two hundred and sixty consecutive patients were retrospectively analyzed: 156 had received between one and six chemoembolization sessions at 3-month intervals, 33 had had PEI, and the remaining 71 patients refused any treatment. The follow-up ranged from 3 to 36 months. Survival rates were statistically analyzed by life-table analysis. Results. Patients' survival was affected by the number of nodules and by the Child's and Okuda's classes; no relationship was found between survival rates and the histologic grade or vascular supply of the tumor. In the case of a single lesion of Okuda's class I, TACE was more effective than PEI. In multifocal HCC, TACE was better than no treatment in Okuda's class I and Child's class A. Conclusion. We suggest TACE as the treatment of choice in Child A or Okuda I patients with multifocal HCCs; it seems of little help in Child B-C or Okuda II-III patients

    We showed in a companion paper that the definition of the French "subcutaneous cellular tissue" considerably varied from the 18th to the end of the 20th centuries and has not yet reached a consensus. To address the anatomic reality of this "subcutaneous cellular tissue", we investigated the anatomic structures underlying the fat tissue in normal human skin. Sixty specimens were excised from the surface to the deep structures (bone, muscle, cartilage) on different body sites of 3 cadavers from the Institut d'Anatomie Normale de Strasbourg. Samples were paraffin-embedded, stained and analysed with a binocular microscope taking x 1 photographs. Specimens were also excised and fixed after subcutaneous injection of Indian ink, after mechanic tissue splitting and after performing artificial skin folds. The aspects of the deep parts of the skin greatly varied according to their anatomic localisation. Below the adipose tissue, we often found a lamellar fibrous layer which extended from the interlobular septa and contained horizontally distributed fat cells. No specific tissue below the hypodermis was observed. Artificial skin folds concerned either exclusively the dermis, when they were superficial or included the hypodermis, but no specific structure was apparent in the center of the fold. India ink diffused to the adipose tissue, mainly along the septa, but did not localise in a specific subcutaneous compartment. This study shows that the histologic aspects of the deep part of the skin depend mainly on the anatomic localisation. Skin is composed of epidermis, dermis and hypodermis and thus the hypodermis can not be considered as being "subcutaneous". A difficult to individualise, fibrous lamellar structure in continuity with the interlobular septa is often found under the fat lobules. This structure is a cleavage line, as is always the case with loose connective tissues, but belongs to the hypodermis (i.e. fat tissue). No specific tissue nor any virtual space was

    Root canal treatment (RoCT), or endodontic treatment, is a common procedure in dentistry. The main indications for RoCT are irreversible pulpitis and necrosis of the dental pulp caused by carious processes, tooth cracks or chips, or dental trauma. Successful RoCT is characterised by an absence of symptoms and clinical signs in teeth without radiographic evidence of periodontal involvement. The success of RoCT depends on a series of variables related to the preoperative condition of the tooth, as well as the endodontic procedures. To compare the effectiveness of single- and multiple-visit RoCT, measured as tooth extraction due to endodontic problems and radiological success.To assess the difference in short- and long-term complications between single- and multiple-visit RoCT. The following databases were searched for relevant trials: Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE, and EMBASE. Handsearching was performed for the major oral medicine journals. References of included studies and reviews were checked. Endodontics experts were contacted through e-mail. No language limitations were imposed. Date of last search was 6th March 2007. Randomised and quasi-randomised controlled trials of patients needing RoCT were included. Surgical endodontic treatment was excluded. The outcomes considered were the number of teeth extracted for endodontic problems; radiological success after at least 1 year, that is, absence of any periapical radiolucency; postoperative pain; painkiller use; swelling; or sinus track formation. Data were collected using a specific extraction form. The validity of included studies was assessed on the basis of allocation concealment, blindness of the study, and loss of participants. Data were analysed by calculating risk ratios. When valid and relevant data were collected, a meta-analysis of the data was undertaken. Twelve randomised controlled trials were included in the review. Four studies had a low risk of bias, four a moderate

    Multiple subcutaneous immunoglobulin (SCIG) products are available to treat primary antibody deficiency (PAD). The efficacy and tolerability of 16% SCIG (Vivaglobin(®) ) was compared with 20% SCIG (Hizentra(®) ) in PAD subjects. The study was a prospective, single-centre, open-label study of PAD subjects transitioning Vivaglobin to equivalent Hizentra doses, rounded to the nearest vial size. Comparisons included immunoglobulin (Ig)G levels; tetanus, varicella and Streptococcus pneumoniae titres; adverse events (AEs), annual infection rate and quality of life during 8 weeks of Vivaglobin and 24 weeks of Hizentra. Thirty-two subjects (aged 2-75 years) participated. Rounding to the nearest Hizentra vial size resulted in a 12·8% (± 2·9%) increase in SCIG dose. Median immunoglobulin (Ig)G level following 8 weeks of Vivaglobin was similar to 24 weeks of Hizentra (1050 versus 1035 mg/dl, respectively; P = 0·77). Both products had similar protective titres to tetanus, varicella and serotypes of S. pneumoniae, which were variable but well above protective levels. After 12 weeks of Hizentra, subjects reported fewer local site reactions compared with Vivaglobin. Switching products resulted in increased systemic AEs in some subjects but, overall, not significantly higher than during Vivaglobin treatment. Average infusion time decreased from 104·7 min (3·3 sites) with Vivaglobin to 70·7 min (2·2 sites) with Hizentra (P = 0·0005). Acute serious bacterial infections were similar. Treatment satisfaction was superior with Hizentra. Hizentra and Vivaglobin have similar pharmacokinetics and efficacy. Although transition to a different SCIG product initially increased AEs, Hizentra is well tolerated and can be infused more rapidly and with fewer sites compared to Vivaglobin. © 2015 British Society for Immunology.

    High-dose intravenous immune globulins (IVIg) are frequently used in refractory juvenile dermatomyositis (JDM) but are often poorly tolerated. High-dose recombinant human hyaluronidase-facilitated subcutaneous immune globulins (fSCIg) allow the administration of much higher doses of immune globulins than conventional subcutaneous immune globulin therapy and may be an alternative to IVIg. The safety and efficacy of fSCIg therapy in JDM is unknown. In this retrospective case series, five patients with steroid-refractory severe JDM were treated with high-dose fSCIg due to IVIg adverse effects (severe headaches, nausea, vomiting, difficult venous access). Peak serum IgG levels, muscle enzymes, the childhood myositis assessment scale and adverse effects were retrieved for at least 6 months following intiation of fSCIg. Data were analyzed by descriptive statistics. Patients initially received fSCIg 1 g/kg every 14 days, resulting in median IgG peak levels of 1901 mg/dl (1606-2719 mg/dl), compared to median IgG peak and trough levels while previously receiving IVIg of 2741 mg/dl (2429-2849 mg/dl) and 1351 mg/dl (1156-1710 mg/dl). Additional antirheumatic therapies consisted of low-dose glucocorticoid therapy, methotrexate, mycophenolate mofetil and/or rituximab. Two patients maintained clinically inactive disease and three patients had only a partial treatment response. In the three patients with partial treatment response, fSCIg 1 g/kg was then given on days 1 and 6 of every 28-day cycle resulting in IgG peak levels of between 2300-2846 mg/dl (previously 1606-1901 mg/dl on the biweekly regimen), resulting in clinically inactive disease in two of the three patients. There were no relevant adverse effects that limited continuation of fSCIg treatment. High-dose fSCIg is well-tolerated in patients with JDM and high peak serum IgG levels can be achieved which may be important for treatment success. High-dose fSCIg may therefore be an alternative to high-dose IVIg

    Currently, urban wastewaters (UWW) laden with organic carbon (BOD) and nutrients (ammoniacal nitrogen, N, and phosphates, P) are treated in multi-stage, energy-intensive process trains to meet the mandated discharge standards. This study presents a single-step process based on mixotrophic metabolism for simultaneous removal of carbon and nutrients from UWWs. The proposed system is designed specifically for hot, arid environments utilizing an acidophilic, thermotolerant algal species, Galdieria sulphuraria, and an enclosed photobioreactor to limit evaporation. Removal rates of BOD, N, and P recorded in this study (14.93, 7.23, and 1.38 mg L(-1) d(-1), respectively) are comparable to literature reports. These results confirm that the mixotrophic system can reduce the energy costs associated with oxygen supply in current UWW treatment systems, and has the potential to generate more energy-rich biomass for net energy extraction from UWW.

    A case of subcutaneous myiasis caused by the larvae of the Dermatobia hominis fly is described, involving the ankle region of a 25-y-old man who had returned from Peru. After removal of 4 larvae from the affected sites, the lesions healed in 2 weeks without further treatment. Because of the increasing number of people travelling to tropical America, physicians in Slovenia will have to consider Dermatobia myiasis in the differential diagnosis of furuncular lesions in patients with a relevant travel history.

    Full Text Available Matteo Caporro, Giulio Disanto, Claudio Gobbi, Chiara Zecca Neurocenter of Southern Switzerland, Ospedale Regionale di Lugano, Lugano, Switzerland Abstract: Glatiramer acetate, a synthetic amino acid polymer analog of myelin basic protein, is one of the first approved drugs for the treatment of relapsing–remitting multiple sclerosis. Several clinical trials have shown consistent and sustained efficacy of glatiramer acetate 20 mg subcutaneously daily in reducing relapses and new demyelinating lesions on magnetic resonance imaging in patients with relapsing–remitting multiple sclerosis, as well as comparable efficacy to high-dose interferon beta. Some preclinical and clinical data suggest a neuroprotective role for glatiramer acetate in multiple sclerosis. Glatiramer acetate is associated with a relatively favorable side-effect profile, and importantly this was confirmed also during long-term use. Glatiramer acetate is the only multiple sclerosis treatment compound that has gained the US Food and Drug Administration pregnancy category B. All these data support its current use as a first-line treatment option for patients with clinical isolated syndrome or relapsing–remitting multiple sclerosis. More recent data have shown that high-dose glatiramer acetate (ie, 40 mg given three times weekly is effective, safe, and well tolerated in the treatment of relapsing–remitting multiple sclerosis, prompting the approval of this dosage in the US in early 2014.This high-dose, lower-frequency glatiramer acetate might represent a new, more convenient regimen of administration, and this might enhance patients’ adherence to the treatment, crucial for optimal disease control.

    Patient compliance is critical for successful allergen immunotherapy (AIT). Previous studies suggest that AIT compliance is worse outside of controlled clinical trials, with reported subcutaneous immunotherapy (SCIT) and sublingual immunotherapy (SLIT) noncompliance at 11% to 50% and 3% to 25%, respectively. A retrospective review of 384 AIT patients at a single, tertiary care otolaryngic allergy practice evaluated SCIT and SLIT compliance, based on treatment stage. SCIT compliance was defined as the number of 2-week breaks per year or in compliance with their defined schedule: excellent = 2 or fewer; good = 3 to 4; fair = 5 to 6; and poor = 7 or more. Compliance with SLIT was defined as the number of days vials were refilled within the defined expiration date: excellent = 10 days or fewer; good = 11 to 15 days, fair = 16 to 20 days; and poor = 25 or more days. Fisher exact and chi square tests were used for statistical analysis. Seventy-four SCIT and 200 SLIT patients had data appropriate for analysis. Compliance rates were excellent (62%) or good (22%) in 62 SCIT patients and excellent (31%) or good (35%) in 131 SLIT patients. Comparing excellent compliance rates, SCIT patients had a higher rate of excellent compliance at all stages of treatment compared to SLIT patients (p 0.05). The results of this study showed higher rates of patient adherence to treatment protocols among SCIT patients. There was no decrease in SCIT compliance rates across treatment stages. © 2015 ARS-AAOA, LLC.

    A decision of the Federal Joint Committee Germany in 2008 stated that negative pressure wound therapy is not accepted as a standard therapy for full reimbursement by the health insurance companies in Germany. This decision is based on the final report of the Institute for Quality and Efficiency in Health Care in 2006, which demonstrated through systematic reviews and meta-analysis of previous study projects, that an insufficient state of evidence regarding the use of negative pressure wound therapy for the treatment of acute and chronic wounds exists. Further studies were therefore indicated. The study is designed as a multinational, multicenter, prospective randomized controlled, adaptive design, clinical superiority trial, with blinded photographic analysis of the primary endpoint. Efficacy and effectiveness of negative pressure wound therapy for wounds in both medical sectors (in- and outpatient care) will be evaluated. The trial compares the treatment outcome of the application of a technical medical device which is based on the principle of negative pressure wound therapy (intervention group) and standard conventional wound therapy (control group) in the treatment of subcutaneous abdominal wounds after surgery. The aim of the SAWHI-VAC® study is to compare the clinical, safety and economic results of both treatment arms. The study project is designed and conducted with the aim of providing solid evidence regarding the efficacy of negative pressure wound therapy. Study results will be provided until the end of 2014 to contribute to the final decision of the Federal Joint Committee Germany regarding the general admission of negative pressure wound therapy as a standard of performance within both medical sectors.

    Palmieri, T J

    1983-03-01

    Subcutaneous hemangiomas, the fourth most common tumor of the hand, consist primarily of proliferating blood vessels within the soft tissue. One hundred and sixty consecutive patients with the histologic diagnosis of subcutaneous hemangiomas were reviewed. Patients with diffuse hemangiomas, strawberry nevi, and arteriovenous fistulae were not included in the study. The median age was 32 years, the youngest being 2 years old and the oldest 68. Sixty-two percent of the patients were female. None had a history of trauma. The palm was the most common location. Progressive enlargement of the lesion and throbbing pain were the most common symptoms. As is characteristic of hemangiomas, they were readily compressible, poorly defined, bluish, subcutaneous masses that distended when the venous return was obstructed and contracted when the extremity was elevated. Roentgenographic evaluation rarely showed the typical calcification of phleboliths, but a soft tissue mass was almost always present. All of these hemangiomas were surgically excised, with the tributory vessels being identified and ligated as far distant from the tumor as possible in order to diminish the chances of recurrence.

    Extruded filaments of unmodified polypropylene (PP) with and without antioxidant were implanted subcutaneously in hamsters in order to determine their rate of degradation. Specimens were removed periodically during a 5 month test period and analyzed by infrared spectroscopy and dynamic mechanical testing. The analyses show that degradation beigns to occur after only a few days. Although the reaction sequence is not known, several factors suggest that the in vivo degradation process is similar to autoxidation which occurs in air or oxygen. The infrared data indicate that the hydroxyl content of the implants increases at a rate of 0.061 mg/g polypropylene per day during the initiation phase of the reaction. An induction time of 108 days was extablished. Carbonyl bonds appear after an implantation time of 50--90 days and increase therafter. Mechanical tests indicate a decrease in the dynamic loss tangent, tan delta, during the first month of implantation for unmodified polypropylene. No change in the infrared spectra or tan delta was observed, however, for implants containing an antioxidant. Thus, it is apparent that polypropylene filaments implanted subcutaneously in hamsters degrade by an oxidation process which is retarded effectively by using an antioxidant. While the findings reported are specific to subcutaneous polypropylene implants, they suggest that degradation of other systems may involve similar processes. This notion suggests directions for further research on increasing the in vivo stability of synthetic polymers. Long-term effects of polymer implantation upon tissue were not studied in this work.

    to compare the outcomes of a regenerative strategy based on recombinant human platelet-derived growth factor-BB (rhPDGF-BB, 0.3 mg/ml) and β-tricalcium phosphate (β-TCP) in the treatment of intraosseous defects accessed with the Single Flap Approach (SFA) versus Double Flap Approach based on papilla preservation techniques (DFA). Fifteen and 13 defects, randomly assigned to SFA or DFA, respectively, were grafted with rhPDGF-BB + β-TCP. Probing parameters were assessed before and 6 months after surgery. Pain (VAS(pain)) was self-reported using a visual analogue scale. Twelve SFA sites and DFA 6 sites showed complete flap closure at 2 weeks post-surgery. No significant differences in 6-month changes in probing parameters and radiographic defect fill were found between groups. Significantly lower VAS(pain) was observed in SFA group compared to DFA group at day +1, +2 and +6. A significantly greater number of analgesics were consumed in the DFA group compared to the SFA group at day +1. When combined with rhPDGF-BB and β-TCP, the SFA may result in similar clinical outcomes, better quality of early wound healing, and lower pain and consumption of analgesics during the first postoperative days compared to the DFA. © 2015 John Wiley & Sons A/S.

    1985-01-01

    The simultaneously recorded disappearance rates of 133 xe from subcutaneous adipose tissue in the crus were studied in 10 patients with psoriasis vulgaris using atraumatic labeling of the tissue in lesional skin (LS) areas and symmetrical, nonlesional skin (NLS) areas. Control experiments were performed bilaterally in 10 younger, healthy subjects. The subcutaneous washout rate constant was significantly higher in LS, 0.79 +/- 0.05 min-1 x 10(2) compared to the washout rate constant of NLS, 0.56 +/- 0.07 min-1. 10(2), or the washout rate constant in the normal subjects, 0.46 +/- 0.17 min-1 x 10(2). The mean washout rate constant in NLS was 25% higher than the mean washout rate constant in the normal subjects. The difference was, however, not statistically significant. Differences in the washout rate constants might be due to abnormal subcutaneous tissue-to-blood partition (lambda) in the LS--and therefore not reflecting the real differences in the subcutaneous blood flow (SBF). The lambda for 133 Xe was therefore measured--using a double isotope washout method ( 133 Xe and [ 131 I]antipyrine)--in symmetrical sites of the lateral crus in LS and NLS of 10 patients with psoriasis vulgaris and in 10 legs of normal subjects. In LS the lambda was 4.52 +/- 1.67 ml/g, which was not statistically different from that of NLS, 5.25 +/- 2.19 ml/g, nor from that of normal subcutaneous tissue, 4.98 +/- 1.04 ml/g. Calculations of the SBF using the obtained lambda values gave a significantly higher SBF in LS, 3.57 +/- 0.23 ml/100 g/min, compared to SBF in the NLS, 2.94 +/- 0.37 ml/100 g/min. There was no statistically significant difference between SBF in NLS and SBF in the normal subjects. The increased SBF in LS of psoriatics might be a secondary phenomenon to an increased heat loss in the lesional skin

    2017-07-01

    Full Text Available Background:. Immediate breast reconstruction is an acceptable treatment option after mastectomy for prophylaxis of early breast cancer. Different options exist for implant placement, incision technique, patient suitability, and institutional experience. This article is a case series exploring the feasibility and outcomes of patients undergoing immediate breast reconstruction using skin-sparing mastectomy without mesh or acellular dermal matrix (ADM and with a vertical inframammary incision. Methods:. A single-institution retrospective analysis was performed for all patients who underwent immediate single-stage reconstruction with subcutaneous silicon implants without ADM between 2009 and 2014 inclusive. Patient, operative and treatment variables were extracted. All patients with viable mastectomy skin flaps intraoperatively and at least 5 mm of subcutaneous tissue were eligible except for patients who were deemed too slim by the senior surgeon preoperatively and thus at risk of implant visibility or skin rippling. Results:. There were 26 patients (bilateral n = 12 and unilateral n = 14 eligible for analysis, with a median long-term follow-up of 51.5 months. The majority of complications were classified as minor affecting 46.2% of the cohort (n = 12. There were 20 episodes of complications overall. The most frequent episodes were contour defects (x = 5, minor seroma (x = 4, and malrotation and minor infection (x = 3. There was 1 episode of capsular contracture. Conclusion:. Skin-sparing mastectomy with immediate subcutaneous silicon implant reconstruction with a vertical incision and without the need for mesh or ADM is an acceptable and safe treatment option. Accurate patient selection and skin flap viability is the key to achieving optimal outcomes with this approach.

  4. Estimates of the effect on hepatic iron of oral deferiprone compared with subcutaneous desferrioxamine for treatment of iron overload in thalassemia major: a systematic review

    2002-11-01

    Full Text Available Abstract Background Beta thalassemia major requires regular blood transfusions and iron chelation to alleviate the harmful accumulation of iron. Evidence on the efficacy and safety of the available agents, desferrioxamine and deferiprone, is derived from small, non-comparative, heterogeneous observational studies. This evidence was reviewed to quantitatively compare the ability of these chelators to reduce hepatic iron. Methods The literature was searched using Medline and all reports addressing the effect of either chelator on hepatic iron were considered. Data were abstracted independently by two investigators. Analyses were performed using reported individual patient data. Hepatic iron concentrations at study end and changes over time were compared using ANCOVA, controlling for initial iron load. Differences in the proportions of patients improving were tested using χ2. Results Eight of 11 reports identified provided patient-level data relating to 30 desferrioxamine- and 68 deferiprone-treated patients. Desferrioxamine was more likely than optimal dose deferiprone to decrease hepatic iron over the average follow-up of 45 months (odds ratio, 19.0, 95% CI, 2.4 to 151.4. The degree of improvement was also larger with desferrioxamine. Conclusions This analysis suggests that desferrioxamine is more effective than deferiprone in lowering hepatic iron. This comparative analysis – despite its limitations – should prove beneficial to physicians faced with the challenge of selecting the optimal treatment for their patients.

  5. Arterial hypertension: second-line treatment. Try other single-agent treatments.

    2008-06-01

    (1) Reliable evidence supports the use of thiazide diuretics (chlortalidone or hydrochlorothiazide) as first-line treatment for uncomplicated arterial hypertension. (2) When patients fail to reach blood pressure targets with well-conducted treatment with thiazide diuretics, or this treatment is poorly tolerated, what are the best second-line options? To answer this question, we reviewed the available evidence, based on our standard in-house methodology. (3) We found no published trials specifically designed to evaluate second-line antihypertensive treatments in cardiovascular prevention. There were no available trials of dual- versus single-agent therapy after failure of a thiazide diuretic. (4) When the blood pressure target is not reached, inadequate drug efficacy is only one of several possible causes. Various other factors affecting blood pressure should also be investigated. (5) Dual-agent therapy carries an increased risk of adverse effects and drug interactions compared to monotherapy. (6) There is no consensus among clinical practice guidelines on second-line antihypertensive therapy. However, to minimise the risk of adverse effects, it is clearly better to select single-agent therapy with a drug that has been shown to prevent cardiovascular events in first-line treatment of otherwise healthy hypertensive patients. Possible options include: angiotensin-converting-enzyme inhibitors, angiotensin II antagonists, calcium channel blockers or betablockers. In patients over the age of 60, betablockers seem less effective that the other drugs in preventing strokes. (7) There is too little evidence to choose a specific third-line combination rather than another. However, any adverse effects that the patient experienced during prior treatments should be taken into account.

She had been diagnosed with dermatomyositis 21 months prior. A thorax computed tomography (CT scan revealed ground glass opacities in her lungs, pneumomediastinum, pneumothorax, and subcutaneous emphysema. Despite intensive immunosuppressive therapy, clinical deterioration and radiological progression were observed, ultimately the patient died. Conclusion:During the care for a patient with dermatomyositis, the otorhinolaryngologist should be cautious of rapidly progressive and fatal neck subcutaneous emphysema. For a patient with dermatomyositis and with normal bronchoscopy and esophagoscopy, the main treatment is control of dermatomyositis with medical therapy. Therefore, a tracheostomy and/or mechanical ventilation may not be necessary.

    To assess the relative bioavailability of a new subcutaneous (SC) diclofenac hydroxypropyl b-cyclodextrin (HPbCD) formulation administered to three body sites: quadriceps, gluteus, and abdomen. This was a pilot, single-dose, randomized, three-way crossover relative bioavailability study. A total of 12 healthy subjects received a single SC injection of diclofenac HPbCD 50 mg/1 mL in the quadriceps, gluteus, or abdomen. The AUC was comparable after SC diclofenac HPbCD in the quadriceps, gluteus, and abdomen. The Cmax was comparable after SC administration in the quadriceps or abdomen, and ~ 17% higher in the gluteus. The absorption was rapid (30 minutes) after administration of the treatment at any site. The treatment was well tolerated. The relative bioavailability of SC diclofenac HPbCD was comparable when administered to the quadriceps, gluteus, and abdomen. The new diclofenac formulation can therefore be administered subcutaneously to any of these sites without clinically significant differences. A further adequately powered study would be necessary to reveal any differences among injection sites in terms of peak plasma concentration.

    The objective of this study is to investigate the efficacy of long-term follow-up of subcutaneous stimulation (SubQ) as an additional therapy for patients with failed back surgery syndrome (FBSS) with chronic refractory pain, for whom spinal cord stimulation (SCS) alone was unsuccessful in treating low back pain. Prospective case series. FBSS patients with leg and/or low back pain whose conventional therapies had failed, received a combination of SCS (8-contact Octad lead, 3877-45 cm, Medtronic, Minneapolis, MN, USA) and/or SubQ (4-contact Quad Plus lead (s), 2888-28 cm, Medtronic). Initially, an Octad lead was placed in the epidural space for SCS for a trial stimulation to assess the suppression of leg and/or low back pain. Where SCS alone was insufficient in treating low back pain, lead(s) were placed superficially in the subcutaneous tissue of the lower back, exactly in the middle of the pain area. A pulse generator (Prime Advanced, 37702, Medtronic) was implanted if the patient reported more than 50% pain relief during the trial period. We investigated the long-term effect of neuromodulation on pain with the visual analog scale (VAS), and disability using the Quebec Pain Disability Scale. The results after 46 months are presented. Eleven patients, five men and six women (age 51 ± 8 years, mean ± SD) were included in the pilot study. In nine cases, SCS was used in combination with SubQ leads. Two patients received only SubQ leads. In one patient, the SCS + SubQ system was removed after nine months and these results were not taken into account for the analysis. Baseline scores for leg (N = 8) and low back pain (N = 10) were VASbl: 59 ± 15 and VASbl: 63 ± 14, respectively. The long-term follow-up period was 46 ± 4 months. SCS significantly reduced leg pain after 12 months (VAS12: 20 ± 11, p12 = 0.001) and 46 months (VAS46: 37 ± 17, p46 = 0.027). Similarly, SubQ significantly reduced back pain after 12 months(VAS12: 33 ± 16, p12 = 0.001) and 46 months

    With the growing number of clinical surgery, post-operative surgical wound infection has become a very difficult clinical problem. In the treatments of it, non-invasive test of wound infection and healing status has a significance in clinical medicine practice. In this paper, beginning with the electrical properties of skin tissue structure and on the basis of the electromagnetism and the human anatomy, using the finite element analysis software, we applied safe voltage on the 3D skin model, performed the subcutaneous pustule simulation study and gained the relational curve between depth and radius of the pustule model. The simulation results suggested that the method we put forward could be feasible, and it could provide basis for non-invasive detection of wound healing and wound infection status.

    Teriparatide, or recombinant human parathyroid hormone, is approved for the treatment of osteoporosis. Possible cutaneous adverse events of teriparatide are urticaria, injection site pain, swelling, bruising, and pruritus. However, there have been no reports of widespread eczematous reactions caused by teriparatide. A 47-year-old male was recently diagnosed with osteogenesis imperfecta and prior to teeth extractions, he was subcutaneously injected with teriparatide. The patient developed multiple pruritic erythematous papules and plaques on his abdomen, around the site of the injection. A skin biopsy was done, which showed mild spongiosis and superficial perivenular lymphocytic infiltration with a few eosinophils. Drug-related eczematous changes were most likely suspected and in addition to the discontinuation of the injection, topical steroid was prescribed, in which dramatic improvements were observed. We report the eczematous hypersensitivity reaction caused by teriparatide, which is an adverse reaction that has not been reported before.

  17. Management of extensive surgical emphysema with subcutaneous drain: A case report

    Directory of Open Access Journals (Sweden)

    Quoc Tran

    Full Text Available Introduction: Subcutaneous emphysema (SE is a frequent and often self-limiting complication of tube thoracostomy or other cardiothoracic procedures. On rare occasions, severe and extensive surgical emphysema marked by palpable cutaneous tension, dysphagia, dysphonia, palpebral closure or associated with pneumoperitoneum, airway compromise, “tension phenomenon” and respiratory failure require treatment. Presentation of case: A 67 year old lady presented with a large spontaneous pneumothorax on the background of end-stage chronic obstructive pulmonary disease (COPD and newly diagnosed lung cancer, developed extensive surgical emphysema following insertion of a chest drain. Immediate improvement was observed after insertion of a large-bore, 26 French (Fr. intercostal catheter, subcutaneous drain which was maintained under low suction (−5 cm H2O for a further 24 h. Discussion: Several methods have been described in the literature for the treatment of extensive subcutaneous emphysema, including: emergency tracheostomy, multisite subcutaneous drainage, infraclavicular “blow holes” incisions and subcutaneous drains or simply increasing suction on an in situ chest drain. Here a large-bore, fenestrated, subcutaneous drain maintained on low negative pressure also provided the necessary decompression. Conclusion: In the absence of a comparative study to identify the most effective method to manage extensive subcutaneous emphysema, this case highlights an effective, simple and safe management option.

    Producing diagnostic antibodies in chicken egg yolk represents an alternate animal system that offers many advantages including high productivity at low cost. Despite being an excellent counterpart to mammalian antibodies, chicken IgG from yolk still represents an underused resource. The potential of agonistic monoclonal anti-CD40 antibodies (mAb) as a powerful immunological adjuvant has been demonstrated in mammals, but not in chickens. We recently reported an agonistic anti-chicken CD40 mAb (designated mAb 2C5) and showed that it may have potential as an immunological adjuvant. In this study, we examined the efficacy of targeting a short peptide to chicken CD40 [expressed by the antigen-presenting cells (APCs)] in enhancing an effective IgG response in chickens. For this purpose, an immune complex consisting of one streptavidin molecule, two directionally biotinylated mAb 2C5 molecules, and two biotinylated peptide molecules was produced. Chickens were immunized subcutaneously with doses of this complex ranging from 10 to 90 μg per injection once, and relative quantification of the peptide-specific IgG response showed that the mAb 2C5-based complex was able to elicit a strong IgG response as early as four days post-immunization. This demonstrates that CD40-targeting antigen to chicken APCs can significantly enhance antibody responses and induce immunoglobulin isotype-switching. This immunization strategy holds promise for rapid production of hapten-specific IgG in chickens. Copyright © 2012 Elsevier B.V. All rights reserved.

    To describe a quick tunnelling technique for peripherally inserted central catheter (PICC) insertion called the "extended subcutaneous route" technique. The "extended subcutaneous route" technique is described step by step. In 18 consecutive PICCs, inserted with extended route technique in ASST Monza, no complications during insertion were registered. In 969 catheter days observed, we identified only one accidental dislodgement. No other mid-term complications were observed. Extended subcutaneous route technique allows the creation of a subcutaneous tunnel <5 cm, without skin incision and additional manipulation. Extended subcutaneous route technique may be feasible and useful, particularly for patients with high risk of bleeding or infection.

  2. Reversible Crystallization of Argatroban after Subcutaneous Application in Pigs

    Full Text Available Argatroban is a thrombin inhibitor used as anticoagulant in patients with heparin-induced thrombocytopenia. It is usually administered as an intravenous bolus followed by infusion. Nevertheless, its pharmacokinetics after subcutaneous administration is unknown. The aim of this study was to assess the pharmacokinetics of two different formulations of argatroban in pigs after subcutaneous administration. Antithrombotic activity in plasma was determined by ecarin chromogenic assay. To visualize the formation of crystals, argatroban was administered to rats into the subcutaneous tissue exposed after removing the skin, and the injection site was photographed at different times. After subcutaneous administration of a sorbitol/ethanol formulation of argatroban in pigs was observed a slow absorption phase was followed by long-lasting levels of this inhibitor. Cmax and AUC(0-24 showed dose-dependent increases, while elimination half-life and tmax value did not change significantly with dose. In contrast, saline-dissolved argatroban showed a faster absorption phase followed by a shorter elimination half-life. Argatroban dissolved in sorbitol/ethanol leads to long-lasting plasma levels due to the formation and permanent dissolution of a crystalline depot at the injection place. This represents a simple way to deliver argatroban continuously over an extended period which can be beneficial for prophylaxis or treatment of chronic coagulations disorders.

    Full Text Available Background. Anemia, a common complication during treatment of malignant disease in children, was frequently treated with red blood cell transfusions. Several studies have shown, that the introduction of recombinant human erythropoietin (rh EPO for treating anemia in patients has been effective in reducing the need for transfusions. Variable doses of EPO from 150 to 900 IU/kg body weight have been used usually three times weekly. Recently some studies showed equally effective once weekly administration of EPO with proposed doses for children of 450 to 600 IU/ kg body weight.Efficacy and safety of once weekly EPO therapy was tested in 8/10 children treated in our Unit for solid tumors and nonHodgkin’s lymphoma. In this article we would like to present our one year experience with EPO treatment.Patients and methods. Patients have subcutaneously received the EPO dose of 600 UI/ kg body weight once weekly. Hemoglobin response and transfusion needs before and during treatment with EPO were analyzed.Results. Response was seen in 7/8 of patient, with increased hemoglobin level and lower transfusion needs. Only one patient was poor responder at first, but responded perfect after twice weekly EPO application. No adverse reaction related to EPO therapy was observed.Conclusions. Our experience with treating anemia in pediatric cancer patients who undergo intensive and aggressive chemotherapy treatment regimens are good and promising. Once weekly dosage regimen is child friendly and acceptable way of treating anemia.

    Lichens are reputedly slow growing and become unhealthy or die in response to supplements of the usual limiting resources, such as water and nitrogen. We found, however, that the tripartite cyanobacterial lichen Lobaria pulmonaria doubled in annual biomass growth after a single 20-minute immersion in a phosphorus solution (K2HPO4), as compared to controls receiving no supplemental phosphorus. This stimulation of cyanolichens by phosphorus has direct relevance to community and population ecology of lichens, including improving models of lichen performance in relation to air quality, improving forest management practices affecting old-growth associated cyanolichens, and understanding the distribution and abundance of cyanolichens on the landscape. Phosphorus may be as important a stimulant to cyanobacterial-rich lichen communities as it is to cyanobacteria in aquatic ecosystems.

    Local ablative therapies such as stereotactically guided single-dose radiotherapy or helical intensity-modulated radiotherapy (tomotherapy) with high single-doses are successfully applied in many centers in patients with liver metastasis not suitable for surgical resection. This study presents results from more than 10 years of clinical experience and evaluates long-term outcome and efficacy of this therapeutic approach. From 1997 to 2009 a total of 138 intrahepatic tumors of 90 patients were irradiated with single doses of 17 to 30 Gy (median dose 24 Gy). Median age of the patients was 64 years (range 31–89 years). Most frequent underlying tumor histologies were colorectal adenocarcinoma (70 lesions) and breast cancer (27 lesions). In 35 treatment sessions multiple targets were simultaneously irradiated (up to four lesions at once). Local progression-free (PFS) and overall survival (OS) after treatment were investigated using uni- and multiple survival regression models. Median overall survival of all patients was 24.3 months. Local PFS was 87%, 70% and 59% after 6, 12 and 18 months, respectively. Median time to local progression was 25.5 months. Patients with a single lesion and no further metastases at time of RT had a favorable median PFS of 43.1 months according to the Kaplan-Meier estimator. The type of tumor showed a statistical significant influence on local PFS, with a better prognosis for breast cancer histology than for colorectal carcinoma in uni- and multiple regression analysis (p = 0.05). Multiple regression analysis revealed no influence of planning target volume (PTV), patient age and radiation dose on local PFS. Treatment was well tolerated with no severe adverse events. This study confirms safety of SBRT in liver lesions, with 6- and 12 months local control of 87% and 70%. The dataset represents the clinical situation in a large oncology setting, with many competing treatment options and heterogeneous patient characteristics

    2016-01-01

    Full Text Available Preperitoneal hematomas are rare and can develop after surgery or trauma. A 74-year-old woman, receiving systemic anticoagulation, developed a massive preperitoneal hematoma after a subcutaneous injection of teriparatide using a 32-gauge, 4 mm needle. In this patient, there were two factors, the subcutaneous injection of teriparatide and systemic anticoagulation, associated with development of the hematoma. These two factors are especially significant, because they are widely used clinically. Although extremely rare, physicians must consider this potentially life-threatening complication after subcutaneous injections, especially in patients receiving anticoagulation.

    Hepatitis C virus (HCV) infection has been linked to lymphoproliferative disorders. Marginal zone B-cell lymphoma (MZL) represents one of the most frequent lymphoma subtypes associated with HCV infection. We describe an unusual subset of HCV-associated MZL characterized by subcutaneous presentation. A series of 12 HCV-positive patients presenting with subcutaneous nodules that revealed lymphoma infiltration at biopsy. Molecular analysis of immunoglobulin heavy chain (IGH) gene rearrangement and FISH investigations for t(11;18)(q21;q21) and t(14;18)(q32;q21) were carried out in nine patients. The 12 patients (median age 69.5 years), all with positive HCV serology, presented with single or multiple subcutaneous nodules resembling lipomas. Histologically the lesions showed lymphoid infiltrates, consistent with extranodal MZL of mucosa-associated lymphoid tissue (MALT). Functional IGH gene rearrangements were identified in nine tested patients, with somatic mutations in 82%, indicating a histogenesis from germinal center-experienced B cells. The t(11;18) was found in two of nine cases. Staging did not show any other lymphoma localization. In two patients, a response was achieved with antiviral treatment. Extracutaneous spread to MALT sites occurred in a case. Our observations expand the spectrum of HCV-associated lymphomas to include a subset of extranodal MZL characterized by a novel primary 'lipoma-like' subcutaneous presentation and indolent clinical course.

    Human subcutaneous dirofilariasis is a rare helminthic infection. It is caused by filarial worms of the Genus Dirofilaria, which is the natural parasites of dogs, cats, foxes, and wild mammals. Zoonotic filariasis caused by Dirofilaria species is rarely seen in the region of Dakshina Kannada. Most of them are seen in patients who are along the border of the district which shares its boundary with the state of Kerala, where dirofilariasis is constantly reported to occur. Here, we report a case of subcutaneous dirofilariasis, presenting as a subcutaneous nodule on the left cheek of a 28-year-old male from Cochin (Ernakulam), Kerala, South India. Two live worms were recovered from the subcutaneous nodular swelling. PMID:23776842

    Full Text Available Abstract Background Involvement of the subcutis by Kaposi sarcoma (KS occurs primarily when cutaneous KS lesions evolve into deep penetrating nodular tumors. Primary KS of the subcutaneous tissue is an exceptional manifestation of this low-grade vascular neoplasm. Case presentation We present a unique case of acquired immune deficiency syndrome (AIDS-associated KS manifesting primarily in the subcutaneous tissue of the anterior thigh in a 43-year-old male, which occurred without overlying visible skin changes or concomitant KS disease elsewhere. Radiological imaging and tissue biopsy confirmed the diagnosis of KS. Conclusion This is the first documented case of primary subcutaneous KS occurring in the setting of AIDS. The differential diagnosis of an isolated subcutaneous lesion in an human immunodeficiency virus (HIV-infected individual is broad, and requires both imaging and a histopathological diagnosis to guide appropriate therapy.

  18. A comparative study of single-dose treatment of chancroid using thiamphenicol versus Azithromycin

    Walter B. Junior

    Full Text Available A study was conducted in São Paulo, Brazil, to compare azithromycin with thiamphenicol for the single-dose treatment of chancroid. In all, 54 men with chancroid were tested. The etiology was determined by clinical characterization and direct bacterioscopy with Gram staining. None of the patients had positive serology or dark-field examination indicating active infection with Treponema pallidum. Genital infections due to Neisseria gonorrhoeae and herpes simplex virus were excluded by polymerase chain reaction testing. For 54 patients with chancroid, cure rates with single-dose treatment were 73% with azithromycin and 89% with thiamphenicol. HIV seropositivity was found to be associated with treatment failure (p=0.001. The treatment failed in all HIV positive patients treated with azithromycin (p=0.002 and this drug should be avoided in these co-infected patients. In the view of the authors, thiamphenicol is the most indicated single-dose regimen for chancroid treatment.

    Full Text Available Microfilariaemia presenting with subcutaneous nodule is rare. We report a case of a 22-year-old female patient who presented with a subcutaneous nodule on right forearm. Fine-needle aspiration cytology from the nodule showed many sheathed motile microfilaria on wet mount preparation during day time. Wuchereria loa loa is known to be associated with soft tissue swellings as reported earlier. Nocturnal motility and cytomorphological features differentiate Wuchereria bancrofti from Wuchereria loa loa.

    Full Text Available The aim of this study was to assess the analgesic effectiveness of three analgesic protocols in dogs undergoing a periodontal treatment. The study was performed as a prospective, randomized, “double blind” clinical study. A total of 45 client-owned dogs scheduled for periodontal treatment were included. Dogs of Group C received carprofen (4 mg·kg-1, dogs of Group B received bupivacaine (1 mg·kg-1 and dogs of Group CB received a combination of carprofen (4 mg·kg-1 and bupivacaine (1 mg·kg-1. Carprofen was administered subcutaneously 30 min before anaesthesia, bupivacaine was administered by nerve blocks in anaesthetized dogs. Painful periodontal treatment was performed in all patients, lasting up to one hour. Modified University of Melbourne Pain Score (UMPS, Visual Analogue Scale for pain assessment (VAS, plasma glucose and serum cortisol levels were assessed 30 min before administration of analgesics (C-0, B-0, CB‑0 and 2 h after recovery from anaesthesia (C-2, B-2, CB-2. For statistical analysis Friedman test, Mann-Whitney U-test, ANOVA and Fischer exact tests were used (P < 0.05. In CB‑2 compared to CB‑0 significantly decreased modified UMPS values. In CB‑2 UMPS values were significantly lower compared to C‑2 or B‑2. In C‑2 VAS values were significantly increased compared to C‑0, and in B‑2 VAS values were significantly increased compared to B‑0. Visual Analogue Scale values were significantly lower in CB‑2 compared to C‑2 or B‑2. Significantly increased plasma glucose concentrations were found in C‑2 compared to C‑0 and in B‑2 compared to B‑0. No other significant differences were detected. Administration of carprofen, bupivacaine or their combination is sufficient for early postoperative analgesia following periodontal treatment. Carprofen-bupivacaine combination is superior to carprofen or bupivacaine administered separately.

    To determine the frequency of flare-ups in single-visit endodontic treatment and the associated factors. Observational. Baqai Dental College Hospital, Karachi, from November 2005 to May 2006. One hundred patients were assigned for single-visit root canal treatment. Patients that defaulted after the first appointment (incomplete treatment) were excluded from the study. For each tooth treated, the clinical factors and conditions existing before and after the completion of treatment were recorded. This data included patient's age, gender, type of tooth, pre-operative status of pulp and periapical tissues and recording pain and swelling (flare-ups) postoperatively after 1 day, 7 days and 1 month. The significance of results was obtained by applying paired-sample t-test and Pearson X2 test. Three of one hundred cases showed flare-ups after treated in single appointment. On the other hand, a marked number (n=97) of cases did not show flare-ups during the study period. None of the studied variables showed any statistically significant bearing on rate of flare-ups in single appointment root canal treatment. The single-visit root canal treatment was safe in terms of endodontic flare-ups as far as results of this study are concerned. It was safer in both vital and non-vital teeth, and even in teeth with periapical pathosis.

    The treatment of gynecomastia depends on multiple factors, and the best modality is controversial. In this study, we aimed to determine the best management approach by comparing outcomes of two groups of patients with gynecomastia who received subcutaneous mastectomy combined with liposuction and liposuction only. We conducted a retrospective analysis of 64 patients who underwent surgery for gynecomastia. We divided the patients into two groups: group A, patients who underwent liposuction only; and group B, patients who underwent liposuction and subcutaneous mastectomy. The serial photographs of all patients were clinically evaluated with respect to size, shape, scarring, and overall outcome by three plastic surgeons, and patient satisfaction was surveyed with regard to palpable lumps, size, shape, scarring, and overall outcome. Of the 64 subjects, 16 received liposuction only, and 48 received the combination procedure. A total of 125 breasts were involved. The doctors' scores for size and overall outcome were significantly better in the combination group, whereas scarring was better in the liposuction-only group. Similarly, patient satisfaction regarding size was significantly higher in the combination group, and satisfaction regarding scarring was significantly higher in the liposuction-only group. The scores for scarring in the combination treatment group were acceptable. Our study shows that combination treatment with liposuction and subcutaneous mastectomy results in satisfactory outcomes, including the extent of scarring. We conclude that this combination treatment should be recommended as the standard surgical treatment for gynecomastia and can provide excellent results in cases where glandular tissue needs to be removed.

    Full Text Available The aim of the study was to compare the development of red blood cell indices after subcutaneous versus intramuscular administration of iron dextran to suckling piglets during early postnatal period. The piglets in group I (n = 17 were injected subcutaneously (into groin with 200 mg Fe3+ as iron dextran on day 3 of life. In group II (n = 16, the piglets received intramuscular injection (into gluteal muscles of 200 mg Fe3+ as iron dextran on day 3 of life. In group III (n = 10, the piglets did not receive any iron till the age of 3 days. The blood was taken and analyzed (Hb, PCV, RBC, MCV, MCH, MCHC, Fe on days 3, 7, 14, 21, 28 and 35. Haematological indices of piglets in group III were characteristic for hypochromic anaemia. Anaemia in group III had a detrimental effect on the growth rate of piglets. The development of red blood cell indices and iron concentration in blood plasma in subcutaneously treated piglets did not differ significantly from that of intramuscularly-treated group. Both treatments prevented development of anaemia.

    Testosterone therapy increases lean body mass and decreases total fat mass in aging men with low normal testosterone levels. The major challenge is, however, to determine whether the metabolic consequences of testosterone therapy are overall positive. We have previously reported that 6-month testosterone therapy did not improve insulin sensitivity. We investigated the effect of testosterone therapy on regional body fat distribution and on the levels of the insulin-sensitizing adipokine, adiponectin, in aging men with low normal bioavailable testosterone levels. A randomized, double-blinded, placebo-controlled study on 6-month testosterone treatment (gel) in 38 men, aged 60-78 years, with bioavailable testosterone 94 cm. Central fat mass (CFM) and lower extremity fat mass (LEFM) were measured by dual X-ray absorptiometry. Subcutaneous abdominal adipose tissue (SAT), visceral adipose tissue (VAT), and thigh subcutaneous fat area (TFA) were measured by magnetic resonance imaging. Adiponectin levels were measured using an in-house immunofluorometric assay. Coefficients (b) represent the placebo-controlled mean effect of intervention. LEFM was decreased (b = -0.47 kg, P = 0.07) while CFM did not change significantly (b = -0.66 kg, P = 0.10) during testosterone therapy. SAT (b = -3.0%, P = 0.018) and TFA (b = -3.0%, P testosterone therapy (b = -1.3 mg/l, P = 0.001). Testosterone therapy decreased subcutaneous fat on the abdomen and lower extremities, but visceral fat was unchanged. Moreover, adiponectin levels were significantly decreased during testosterone therapy.

  8. Subcutaneous emphysema of the upper extremity following penetrating blackthorn injury to the wrist.

    2009-02-01

    SUMMARY: Noninfective subcutaneous emphysema of the upper extremity, albeit rare, has to be borne in mind when treating patients with subcutaneous emphysema. The misdiagnosis of this condition as its serious infective counterpart often leads to unnecessary aggressive treatment. Noninfective subcutaneous emphysema often accompanies a patient who has no systemic symptoms of illness. Unfortunately, the distinction is not always easy especially when history of injury suggests involvement of an infective or reactive element. Penetrating blackthorn injury is common, especially in rural communities, and often occurs from farming or gardening activities. Blackthorn penetration can cause numerous tissue reactions once embedded under the skin and they are often contaminated with soil. Here we present, for the first time, a case where penetrating blackthorn injury to the wrist resulted in noninfective subcutaneous emphysema involving the whole upper limb and neck, and its subsequent management.

    From the available literature, it is demonstrated that dematiaceous fungal infections mostly affect immunosuppressed patients. These infections can occur in different forms, from subcutaneous infection to disseminated forms that may compromise the life of the patient. In many cases the infection is related to the inoculation of the microorganism by diverse traumatic mechanisms, which determines the course of the infection to be slower in some cases. We describe two cases of phaeohyphomycosis caused by Phaeoacremonium parasiticum: A cancer patient with subcutaneous lesions affecting the left hand and forearm, and a patient who presented with subcutaneous abscesses in the left leg. These cases confirm the presence of this type of fungus in Spain. In the second case a combination of amphotericin B lipid complex and posaconazole, together with several surgical resections, were necessary in order to overcome the infection.

  10. Hypertrophic Obesity and Subcutaneous Adipose Tissue Dysfunction

    2014-08-01

    Full Text Available BACKGROUND: Over the past 50 years, scientists have recognized that not all adipose tissue is alike, and that health risk is associated with the location as well as the amount of body fat. Different depots are sufficiently distinct with respect to fatty-acid storage and release as to probably play unique roles in human physiology. Whether fat redistribution causes metabolic disease or whether it is a marker of underlying processes that are primarily responsible is an open question. CONTENT: The limited expandability of the subcutaneous adipose tissue leads to inappropriate adipose cell expansion (hypertrophic obesity with local inflammation and a dysregulated and insulin-resistant adipose tissue. The inability to store excess fat in the subcutaneous adipose tissue is a likely key mechanism for promoting ectopic fat accumulation in tissues and areas where fat can be stored, including the intra-abdominal and visceral areas, in the liver, epi/pericardial area, around vessels, in the myocardium, and in the skeletal muscles. Many studies have implicated ectopic fat accumulation and the associated lipotoxicity as the major determinant of the metabolic complications of obesity driving systemic insulin resistance, inflammation, hepatic glucose production, and dyslipidemia. SUMMARY: In summary, hypertrophic obesity is due to an impaired ability to recruit and differentiate available adipose precursor cells in the subcutaneous adipose tissue. Thus, the subcutaneous adipose tissue may be particular in its limited ability in certain individuals to undergo adipogenesis during weight increase. Inability to promote subcutaneous adipogenesis under periods of affluence would favor lipid overlow and ectopic fat accumulation with negative metabolic consequences. KEYWORDS: obesity, adipogenesis, subcutaneous adipose tissue, visceral adipose tissue, adipocyte dysfunction.

    Full Text Available Abstract Background In an event of a smallpox outbreak in humans, the window for efficacious treatment by vaccination with vaccinia viruses (VACV is believed to be limited to the first few days post-exposure (p.e.. We recently demonstrated in a mouse model for human smallpox, that active immunization 2–3 days p.e. with either VACV-Lister or modified VACV Ankara (MVA vaccines, can rescue animals from lethal challenge of ectromelia virus (ECTV, the causative agent of mousepox. The present study was carried out in order to determine whether a single dose of the anti-viral cidofovir (CDV, administered at different times and doses p.e. either alone or in conjunction with active vaccination, can rescue ECTV infected mice. Methods Animals were infected intranasally with ECTV, treated on different days with various single CDV doses and monitored for morbidity, mortality and humoral response. In addition, in order to determine the influence of CDV on the immune response following vaccination, both the "clinical take”, IFN-gamma and IgG Ab levels in the serum were evaluated as well as the ability of the mice to withstand a lethal challenge of ECTV. Finally the efficacy of a combined treatment regime of CDV and vaccination p.e. was determined. Results A single p.e. CDV treatment is sufficient for protection depending on the initiation time and dose (2.5 – 100 mg/kg of treatment. Solid protection was achieved by a low dose (5 mg/kg CDV treatment even if given at day 6 p.e., approximately 4 days before death of the control infected untreated mice (mean time to death (MTTD 10.2. At the same time point complete protection was achieved by single treatment with higher doses of CDV (25 or 100 mg/kg. Irrespective of treatment dose, all surviving animals developed a protective immune response even when the CDV treatment was initiated one day p.e.. After seven days post treatment with the highest dose (100 mg/kg, virus was still detected in some

    Dens invaginatus is a dental malformation that may give rise to several complications. Caries of the invagination can severely weaken the whole tooth, making it susceptible to fracture. Subgingival fractures are major complications threatening tooth survival and usually require periodontal/orthodontic/prosthetic treatment if long-term viability is to be ensured. This article describes a case of single-session restoration of a fractured invaginated tooth by means of endodontic treatment followed by fragment reattachment.

    Three type I diabetic patients nonresponsive to subcutaneous insulin were implanted with a subcutaneous peritoneal access device. In these patients, multiple subcutaneous injections had been unable to prevent recurrent hospital admissions for diabetic ketoacidosis. The patients were responsive to intravenous insulin but had limited accessible peripheral veins. Complications of thrombosis and/or septicemia from permanent central venous catheters prevented the long-term use of this route. The peritoneal access device was implanted subcutaneously adjacent to the umbilicus with its insulin delivery catheter terminating in the peritoneal space. Transcutaneous injection of insulin into the subcutaneous access port resulted in the same quantity of insulin entering the peritoneal space. Using a mixture of regular and protamine zinc insulin in a ration of 1:1 resulted in acute increases in plasma free insulin concentration with meals and a declining background level postprandially. All peritoneal access devices have been functioning well for at least 2 mo and in one of the implanted diabetic subjects, it has been in continuous use for 5 mo with no evidence of peritonitis or resistance to peritoneal insulin. These results suggest that a subcutaneous peritoneal access device may provide an alterative insulin delivery route for patients who are nonresponsive to subcutaneous insulin injections.

    Teriparatide acetate was developed in the form of a synthetic analogue of the Nterminal peptide (1-34) of human parathyroid hormone for the treatment of osteoporosis; it is administered subcutaneously once weekly. However, it is not known whether the pharmacokinetics (PK) of this drug is affected by renal impairment, and this study was conducted to look into this question. A multi-center study was conducted at six hospitals in Japan. Subjects were enrolled and grouped on the basis of renal function stratified as: normal function to mild renal impairment (estimated GFR(e-GFR): ≥ 60.0 mL/min/1.73 m2) (8 subjects), moderate impairment (eGFR: 30.0 - 59.9 mL/min/1.73 m2) (5 subjects), and severe impairment (eGFR: 15.0 - 29.9 mL/min/1.73 m2) (5 subjects). The PK parameters, blood and urine electrolytes concentrations, and safety profiles were assessed following a single subcutaneous injection of teriparatide acetate (56.5 μg as teriparatide). The elimination half-life (t1/2) and the mean residence time extrapolated to infinity were significantly prolonged in the group with severe renal impairment (t1/2: 5.0 hours) compared with normal to mild and moderate impairment groups (t1/2: 1.5 hours and 1.2 hours, respectively). However, virtually all of the teriparatide was eliminated from the blood after 24 hours. Given that the drug is administered once weekly, it appeared highly unlikely that accumulation of the drug in the body would become a problem even with repeated administration. There were no particular problems with safety or tolerability. In treatment with teriparatide acetate once-per week formulation, prescription at the usual dosage appears to be appropriate even in renally impaired patients.

    Allergen immunotherapy (AIT) is an effective way to treat allergic disorders, targeting the underlying mechanisms and altering the disease course by inducing a long-lasting clinical and immune tolerance to allergens. Although sublingual and subcutaneous routes are used in daily practice, many novel ways to decrease side effects and duration and increase efficacy have been pursued. Further studies are needed to develop biomarkers for the identification of AIT responder patients and also to use the developed knowledge in allergy prevention studies. Future directions in AIT include treatments for autoimmune diseases, chronic infections, organ transplantation, and breaking immune tolerance to cancer cells. Copyright © 2016 Elsevier Inc.

    Full Text Available Crossbite can be treated using both removable and fixed appliances. This paper describes the report of two cases by a method of treating anterior single tooth in crossbite which is locked out of arch form with a simple fixed partial appliance. Orthodontic treatment was initiated by creating space for the locked out incisor using open coil spring and further corrected using MBT brackets and nitinol archwire for alignment. Treatment goals were achieved, and esthetics and occlusion were maintained postoperatively. Treatment objectives were obtained within a short duration using this technique, and there was an improvement in patients' smile.

    Full Text Available This study compared the thermal changes of cutaneous and subcutaneous tissues exposed to different aerosols. Thirty-six adults Wistar rats were arranged in two treatment groups, one exposed to methyl salicylate (GSM; n = 9 skin and n = 9 subcutaneous and the other exposed to diclofenac diethylammonium (GDD; n = 9 skin and n = 9 subcutaneous aerosols. Five jets were applied for one-second through an apparatus to reduce spray dispersion (3 cmdiameter in the lateral left thigh of the animals. Temperatures were measured every minute (min. during 30 min., with a digital thermometer. In the skin tissue the sensor was positioned manually, in the subcutaneous tissue it was surgically inserted through the rear face and positioned in the lateral thigh. The skin temperature has homogeneously reduced in both groups. In the subcutaneous tissue the GDD has induced hypothermia from the 2nd to 20th min., the lowest temperature was recorded on the 7th min. (-3.6 ± 0.2ºC in relation to basal. Lowering the temperature by GSM took place from the 1st to 21st min, and the lowest temperature occurred on the 1st min (-9.7 ± 0.5ºC in relation to basal. In the three initial minutes the GSM had temperatures 25, 10 and 5% lower than the GDD. Aerosols have induced hypothermia in the tissues, while the GSM has decreased faster and reached lower values of temperature shown in the subcutaneous tissue.

To compare the treatment success rates and adverse effect rates of single-dose and non-single-dose (two-dose and multi-dose) methotrexate protocols in the treatment of ectopic pregnancy. Various databases including Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched on July 1, 2017, using search terms including "methotrexate" and "pregnancy." Randomized controlled trials comparing different methotrexate protocols for the treatment of ectopic pregnancy were included. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated to compare treatment success rates and adverse effect rates. The single-dose and non-single-dose protocols had similar success rates (RR 1.00, 95% CI 0.96-1.04; 11 trials, 1121 patients, I 2 =18%). The non-single-dose protocols had a higher adverse effect rate than did the single-dose protocol (RR 0.73, 95% CI 0.59-0.91; nine trials, 934 patients, I 2 =0%). The single-dose methotrexate protocol was the optimal protocol for the medical treatment of ectopic pregnancy. © 2018 International Federation of Gynecology and Obstetrics.

    We report on Ytterbium and Neodymium codoped LaF{sub 3} core/shell nanoparticles capable of simultaneous heating and thermal sensing under single beam infrared laser excitation. Efficient light-to-heat conversion is produced at the Neodymium highly doped shell due to non-radiative de-excitations. Thermal sensing is provided by the temperature dependent Nd{sup 3+} → Yb{sup 3+} energy transfer processes taking place at the core/shell interface. The potential application of these core/shell multifunctional nanoparticles for controlled photothermal subcutaneous treatments is also demonstrated.

    African pygmy hedgehogs (Atelerix albiventris) are popular pets belonging to the Erinaceidae family of spined mammals. Amongst the most common skin diseases occurring in this species is infestation caused by the mite Caparinia spp. Due to their skin anatomy and spiny coat, detection of skin lesions in these hedgehogs can be difficult. This may result in delays in seeking medical care, which may lead to secondary bacterial infection and self-inflicted trauma. Multiple therapies have been used in the treatment of this skin condition including ivermectin, amitraz, fipronil and selamectin. A drug which could be administered as a single oral dose would be advantageous to these pets and their owners. To evaluate the effect of a single oral dose (15 mg/kg) of fluralaner on Caparinia tripilis infestation in the African pygmy hedgehog. A 10-month-old African pygmy hedgehog weighing 184 g. Response to treatment was monitored by dermatological examination and superficial skin scrapings repeated at 7, 14, 21, 30, 60, 90 and 120 days following fluralaner administration. On Day 7 after treatment, adult mites were observed exhibiting normal movement. On Day 14, only dead mites were observed. No life stages of the mites were found after Day 21. A single oral dose at 15 mg/kg of fluralaner was effective within 21 days after treatment for capariniasis in this case. Further studies are required to evaluate the drug's safety and toxicology in hedgehogs, and to confirm efficacy. © 2017 ESVD and ACVD.

    Purpose: To develop a combined simulation and treatment workflow for MRI-guided radiation therapy using the ViewRay treatment planning and delivery system. Methods: Several features of the ViewRay MRIdian planning and treatment workflows are used to simulate and treat patients that require emergent radiotherapy. A simple “pre-plan” is created on diagnostic imaging retrieved from radiology PACS, where conformal fields are created to target a volume defined by a physician based on review of the diagnostic images and chart notes. After initial consult in radiation oncology, the patient is brought to the treatment room, immobilized, and imaged in treatment position with a volumetric MR. While the patient rests on the table, the pre-plan is applied to the treatment planning MR and dose is calculated in the treatment geometry. After physician review, modification of the plan may include updating the target definition, redefining fields, or re-balancing beam weights. Once an acceptable treatment plan is finalized and approved, the patient is treated. Results: Careful preparation and judicious choices in the online planning process allow conformal treatment plans to be created and delivered in a single, thirty-minute session. Several advantages have been identified using this process as compared to conventional urgent CT simulation and delivery. Efficiency gains are notable, as physicians appreciate the predictable time commitment and patient waiting time for treatment is decreased. MR guidance in a treatment position offers both enhanced contrast for target delineation and reduction of setup uncertainties. The MRIdian system tools designed for adaptive radiotherapy are particularly useful, enabling plan changes to be made in minutes. Finally, the resulting plans, typically 6 conformal beams, are delivered as quickly as more conventional AP/PA beam arrangements with comparatively superior dose distributions. Conclusion: The ViewRay treatment planning software and

    The burden of revision arthroplasty surgery for infection is rising as the rate of primary arthroplasty surgery increases. Infected arthroplasty rates are now relatively low, but the sheer increase in volume is leading to considerable patient morbidity and significant increases in costs to the health care system. Single-stage revision for infection is one of the several accepted treatment options, but the indications and results are debated. This review aims to clarify the current evidence. MEDLINE/PubMed databases were reviewed for studies that looked at single- or one-stage revision knee or hip arthroplasty for infection. There is increasing evidence that single-stage revision for infection can control infection and with decreased morbidity, mortality, and health care costs compared with a staged approach. However, the indications are still debated. Recently, there has been a determined effort to define an infected arthroplasty in a manner that will allow for standardization of reporting in the literature. The evidence supporting single stage for knee arthroplasty is catching up with the result with hip arthroplasty. High-quality data from randomized controlled trials are now pending. After the gradual evolution of using the single-stage approach, with the widespread acceptance of this definition, we can now standardize comparisons across the world and move toward a refined definition of the ideal patient population for single-stage arthroplasty revision in both the hip and the knee population.

    To investigate the efficacy of progressive addition lenses on the treatment of ametropia and loss of accomodation after the single eye's IOL implantation. Eighty four patients undergoing IOL implantation in single eyes were prescribed with progressive addition lenses for ametropia correction and regularly followed up to observe subsequent correction effect. Among these 84 patients, 72 could comfortably adapt to the use of progressive addition lenses to improve visual acuity and accomondation, while the remaining 12 patients failed to accomodate the usage of progressive addition lenses. Wearing progressive addition lenses acts as a relatively feasible approach to improve visual acuity and alleviate disorders of accomodation for patients who underwent IOL implantation in single eyes. The patients should be prescribed with progressive lenses under professional instructions and guidance.

    Obesity is strongly associated with the risks of diabetes and cardiovascular disease, and there is a need to measure the subcutaneous adipose tissue (SAT) layer thickness and to understand the distribution of body fat. A device was designed to illuminate the body parts by near-infrared (NIR), measure the backscattered light, and predict the SAT layer thickness. The device was controlled by a single-chip microcontroller (SCM), and the thickness value was presented on a liquid crystal display (LCD). There were 30 subjects in this study, and the measurements were performed on 14 body parts for each subject. The paper investigated the impacts of pressure and skin colour on the measurement. Combining with principal component analysis (PCA) and support vector regression (SVR), the measurement accuracy of SAT layer thickness was 89.1 % with a mechanical caliper as reference. The measuring range was 5–11 mm. The study provides a non-invasive and low-cost technique to detect subcutaneous fat thickness, which is more accessible and affordable compared to other conventional techniques. The designed device can be used at home and in community.

    Full Text Available Objective. The purposes of this study were to determine whether secnidazole administered at a single dose of 10 mg/kg, orally, lessens or eliminates Giardia cyst shedding, and to validate the benefit of secnidazole treatment on clinical signs and faecal consistency in lambs naturally infected with Giardia duodenalis. Materials and methods. To this extent weaned 12 weeks of age lambs were selected and randomly assigned into two groups based on placebo (group C, n=7 untreated control group or treatment (group S, n=10 lambs treated with a single dose of secnidazole at 10 mg/kg. Results. On days 0 and 10, before and after treatment, respectively, reduction in cyst excretion was determined. The faecal consistency and general health were recorded at each sampling day. Conclusions. During the study there was a high (99.98% reduction in cyst excretion in the secnidazol treatment group compared to the positive control group on day 10, resulting in a significant (p<0.001 reduction, making secnidazole highly effective treatment option.

    While complex symptom scales are important research tools, simpler, preferably single item scales may be more useful for routine clinical practise in the evaluation of patients with overactive bladder syndrome (OAB). This study aimed to compare multiple single-item scales at baseline and after treatment with patient-reported overall rating of treatment efficacy. In a pre-planned secondary analysis of a previously reported observational study, 4,450 patients were evaluated at baseline and after 12 weeks open-label treatment with solifenacin. Apart from episode counting for classical OAB symptoms, the following single-item rating scales were applied: Indevus Urgency Severity Scale, Urgency Perception Scale, a Visual Analog Scale (VAS), quality of life question of the IPSS, and general health and bladder problem questions of the King's Health Questionnaire (KHQ). At baseline OAB symptoms correlated at best moderately with each (r = 0.285-0.508) other or with any of the rating scales (r = 0.060-0.399). Pair-wise correlations between treatment-associated symptom or scale improvements tended to be tighter (r = 0.225-0.588). When compared to patient-reported efficacy, the VAS (r = 0.487) and the bladder problem question of the KHQ (r = 0.452) showed the tightest correlation, whereas all symptom and rating scale improvements exhibited poor correlation with patient-reported tolerability (r ≤ 0.283). The VAS and the bladder problem question of the KHQ show the greatest promise as single-item scales to assess problem intensity in OAB patients. Copyright © 2011 Wiley-Liss, Inc.

    With the Food and Drug Administration's approval of sublingual allergen-specific immunotherapy (SL-AIT) tablets for grass and ragweed pollen, SL-AIT is progressively gathering importance not only in Europe, but also in the United States and other parts of the world. We reviewed issues related to the selection of patients for the sublingual or the subcutaneous route for allergic patients, based on what has been published since January 2014 on subcutaneous-versus-SL-AIT efficacy, safety and other issues. (Figure is included in full-text article.) As patient's adherence seems one of the major problems in real-life AIT, investigators have sought how to enhance AIT simplicity by changing the route to home-administrated SL-AIT, and by shortening the subcutaneous-allergen-specific immunotherapy (SC-AIT) build-up or maintenance phase. The latter was safe with several hypoallergenic extracts. As for SL-AIT, double blind placebo-controlled large trials in patients with allergic rhinitis and asthma have shown the efficacy and safety of ragweed pollen and house dust mite SLIT tablets and highly concentrated liquid formulations, primarily in adults. A large trial with SLIT in 3-year-old children was effective. With the improvement of SL-AIT efficacy, the selection of SC-versus-SL-AIT will probably increasingly be based not on efficacy, but on practical aspects, without losing sight of which SL-AIT products have proven efficacy.

    The purpose of this study was to evaluate the effect of 2.5°C cold saline irrigation as final irrigant on postoperative pain after single-visit root canal treatment of teeth with vital pulps. One-hundred and seventy patients were assessed as eligible and included to the study. The teeth were randomly divided into two groups (n = 85) (i.e. the control group and the cryotherapy group). In the cryotherapy group, final irrigation with 2.5°C 0.9% physiological saline solution for 5 min was performed following completion of biomechanical preparation, whereas in control group same solution stored at the root temperature was used. Treatments were performed in a single visit. Participants were asked to rate the intensity of their postoperative pain using visual analogue scale at 24 and 48 h. Data were analysed by Mann-Whitney U test and Student's t test. In the cryotherapy group level of reported postoperative pain was significantly lower than the control group (P < 0.05, Mann-Whitney U test). The outcome of this investigation indicates that 2.5°C cold saline irrigation as final irrigant can result a significant reduction in postoperative pain levels in comparison to the control group. Cryotherapy is a simple, cost-effective, and non-toxic option for postoperative pain control in single visit root canal treatment. © 2016 Australian Society of Endodontology Inc.

  4. Are medical treatments for individuals and groups like single-play and multiple-play gambles?

    Full Text Available People are often more likely to accept risky monetary gambles with positive expected values when the gambles will be played more than once. We investigated whether this distinction between single-play and multiple-play gambles extends to medical treatments for individual patients and groups of patients. Resident physicians and medical students (extit{n} = 69 and undergraduates (extit{n} = 99 ranked 9 different flu shots and a no-flu-shot option in 1 of 4 combinations of perspective (individual patient vs. group of 1000 patients and uncertainty frame (probability vs. frequency. The rank of the no-flu-shot option (a measure of preference for treatment vs. no treatment was not significantly related to perspective or participant population. The main effect of uncertainty frame and the interaction between perspective and uncertainty frame approached significance (0.1 {extgreater} extit{p} {extgreater} 0.05, with the no-flu-shot option faring particularly poorly (treatment faring particularly well when decisions about many patients were based on frequency information. Undergraduate participants believed that the no-flu-shot option would be less attractive (treatment would be more attractive in decisions about many patients, but these intuitions were inconsistent with the actual ranks. These results and those of other studies suggest that medical treatments for individuals and groups are not analogous to single-play and multiple-play monetary gambles, perhaps because many people are unwilling to aggregate treatment outcomes over patients in the same way that they would compute net gains or losses over monetary gambles.

    To compare the efficacy of subcutaneous only and combined subcutaneous and peritoneal infiltration of 0.5% bupivacaine during appendicectomy for the management of early post operative pain. Study Design: Randomized controlled study. Place and Duration of Study: Department of Surgery, CMH Kohat from 13th December 2007 to 20th December 2008. Patients and Methods: Sixty patients of a cute appendicitis, divided into two groups of 30 each, were included in the study. Group A was given 0.5% bupivacaine subcutaneously, whereas group B was given the anaesthetic subcutaneously as well as intraperitoneally during appendectomy. Results: In group A, 24 (80%) were VAS (visual analoguescoring) 3 (uncomfortable) and 6 (20%) were VAS 2 (mild pain) whereas in study group B, 11 (36.6%) were VAS 3, 19 (63.3%) were VAS 2 and 19 (63.3%) were VAS 2 during 1st 12 hrs postoperatively (p=0.001). In 12-24 hrs post operatively, 15 (50%) patients were VAS 3 in group A and same number was VAS 2 and in group B, only 3 (10%) were in VAS 3 and 27 (90%) were VAS 2 (p=0.001). Conclusion: A combination of subcutaneous and peritoneal infiltration with bupivacaine is superior in relieving post appendectomy pain so patients require less dosage of analgesics in early post operative period along with early mobilization.

    Stereotactic-Radio-Surgery (SRS) using Conformal-Arc-Therapy (CAT) is a well established irradiation technique for treatment of intracranial targets. Although small safety margins are required because of very high accuracy of patient positioning and exact online localisation, there are still disadvantages like long treatment time, high number of monitor units (MU) and covering of noncircular targets. This planning study analysed whether Rapid Arc (RA) with stereotactic localisation for single-fraction SRS can solve these problems. Ten consecutive patients were treated with Linac-based SRS. Eight patients had one or more brain metastases. The other patients presented a symptomatic vestibularis schwannoma and an atypic meningeoma. For all patients, two plans (CAT/RA) were calculated and analysed. Conformity was higher for RA with additional larger low-dose areas. Furthermore, RA reduced the number of MU and the treatment time for all patients. Dose to organs at risk were equal or slightly higher using RA in comparison to CAT. RA provides a new alternative for single-fraction SRS irradiation combining advantages of short treatment time with lower number of MU and better conformity in addition to accuracy of stereotactic localisation in selected cases with uncomplicated clinical realization

    The effectiveness of endodontic treatment regarding the number of sessions to complete the therapy is still controversial. The aim of this study was to conduct an overview of published systematic reviews (SRs) comparing endodontic treatment in single and multiple visits. A systematic search was performed in the electronic databases MEDLINE/PubMed and Cochrane Central Register of Controlled Trials until August 18, 2016, without language restriction. The eligibility criteria were as follows: (1) SRs and (2) a focus on endodontic techniques in single or multiple visits. The phases of eligibility and analysis of risk of bias were conducted by 2 or 3 independent and calibrated examiners, and a fourth examiner was consulted to resolve inconsistencies. Assessment of Multiple Systematic Reviews was used to evaluate the risk of bias of the included SRs, which were assessed according to the risk to develop knowledge and the existing knowledge gap. The main characteristics including healing rates, success, and clinical complications during and after endodontic treatment were extracted from the SRs. From the 20 SRs initially identified, 8 were included in the analysis. Of these, 6 SRs showed low to moderate risk of bias and were suitable as strong clinical evidence on the topic. Overall analysis indicated that single and multiple visits showed similar repair or success rates regardless of the precondition of the pulp and periapex. The apical periodontitis subgroup showed a slight positive trend toward a decreased incidence of postoperative complications and a higher effectiveness and efficiency for a single session. Based on the risk of bias, the current level of evidence for this clinical approach is high. Copyright © 2017 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    The toxic effect of single and binary treatments of synthetic and plant-derived molluscicides was studied against the harmful terrestrial snail Achatina fulica. In single treatments, among the synthetic molluscicides Snail Kill and cypermethrin were potent, whereas Cedrus deodara oil was more toxic among molluscicides of plant origin against A. fulica. In binary treatments, a combination of Cedrusdeodara + Alliumsativum was more toxic. The toxicities of these single and binary treatments of synthetic and plant-derived molluscicides were dose and time dependent. Copyright 2002 John Wiley & Sons, Ltd.

    Default from tuberculosis (TB) treatment could exacerbate the disease and result in the emergence of drug resistance. This study identified the risk factors for default from TB treatment in Korea. This single-center case-control study analyzed 46 default cases and 100 controls. Default was defined as interrupting treatment for 2 or more consecutive months. The reasons for default were mainly incorrect perception or information about TB (41.3%) and experience of adverse events due to TB drugs (41.3%). In univariate analysis, low income (defaulter (15.2% vs. 2.0%, P = 0.005), and combined extrapulmonary TB (54.3% vs. 34.0%, P = 0.020) were significant risk factors for default. In multivariate analysis, the absence of TB stigma (adjusted odd ratio [aOR]: 46.299, 95% confidence interval [CI]: 8.078-265.365, P defaulters (aOR: 33.226, 95% CI: 2.658-415.309, P = 0.007), and low income (aOR: 5.246, 95% CI: 1.249-22.029, P = 0.024) were independent predictors of default from TB treatment. In conclusion, patients with absence of disease stigma, treated by a non-pulmonologist, who were former defaulters, and with low income should be carefully monitored during TB treatment in Korea to avoid treatment default.

    Default from tuberculosis (TB) treatment could exacerbate the disease and result in the emergence of drug resistance. This study identified the risk factors for default from TB treatment in Korea. This single-center case–control study analyzed 46 default cases and 100 controls. Default was defined as interrupting treatment for 2 or more consecutive months. The reasons for default were mainly incorrect perception or information about TB (41.3%) and experience of adverse events due to TB drugs (41.3%). In univariate analysis, low income (defaulter (15.2% vs. 2.0%, P = 0.005), and combined extrapulmonary TB (54.3% vs. 34.0%, P = 0.020) were significant risk factors for default. In multivariate analysis, the absence of TB stigma (adjusted odd ratio [aOR]: 46.299, 95% confidence interval [CI]: 8.078–265.365, P defaulters (aOR: 33.226, 95% CI: 2.658–415.309, P = 0.007), and low income (aOR: 5.246, 95% CI: 1.249–22.029, P = 0.024) were independent predictors of default from TB treatment. In conclusion, patients with absence of disease stigma, treated by a non-pulmonologist, who were former defaulters, and with low income should be carefully monitored during TB treatment in Korea to avoid treatment default.

    The response of cells to a chemical or biological agent in terms of their impedance changes in real-time is a useful mechanism that can be utilized for a wide variety of biomedical and environmental applications. The use of a single-cell-based analytical platform could be an effective approach to acquiring more sensitive cell impedance measurements, particularly in applications where only diminutive changes in impedance are expected. Here, we report the development of an on-chip cell impedance biosensor with two types of electrodes that host individual cells and cell populations, respectively, to study its efficacy in detecting cellular response. Human glioblastoma (U87MG) cells were patterned on single- and multi-cell electrodes through ligand-mediated natural cell adhesion. We comparatively investigated how these cancer cells on both types of electrodes respond to an ion channel inhibitor, chlorotoxin (CTX), in terms of their shape alternations and impedance changes to exploit the fine detectability of the single-cell-based system. The detecting electrodes hosting single cells exhibited a significant reduction in the real impedance signal, while electrodes hosting confluent monolayer of cells showed little to no impedance change. When single-cell electrodes were treated with CTX of different doses, a dose-dependent impedance change was observed. This enables us to identify the effective dose needed for this particular treatment. Our study demonstrated that this single-cell impedance system may potentially serve as a useful analytical tool for biomedical applications such as environmental toxin detection and drug evaluation.

    To assess the safety and tolerability of switching between subcutaneous (SC) and intravenous (IV) trastuzumab in the PrefHer study (NCT01401166). Patients with HER2-positive early breast cancer completed (neo)adjuvant chemotherapy and were randomised to receive four cycles of SC trastuzumab, via single-use injection device (SID; Cohort 1) or hand-held syringe (Cohort 2), followed by four cycles of IV, or vice versa (the crossover period presented here) as part of their 18 standard cycles of adjuvant trastuzumab treatment. Adverse events (AEs) were reported using standard criteria. Overall, fewer AEs were reported during the IV treatment periods, regardless of administration sequence (IV→SC or SC→IV). Differences in AEs between the SC and IV periods were partly due to variances in grade 1 and 2 local injection site reactions (ISRs) and systemic administration-related reactions (ARRs) and these occurred mainly during SC treatment, as expected. When ISRs and ARRs were excluded, rates of AEs were higher during the first treatment period, compared with the second, in both treatment sequences; otherwise there was no clear pattern in the type of AEs reported. Rates of clinically important events, including grade ≥3 AEs, serious AEs, AEs leading to study drug discontinuation and cardiac AEs, were low and similar between treatment arms (<5%). There were no grade 4 or 5 AEs. No new safety signals for trastuzumab were observed. PrefHer revealed that switching from IV to SC trastuzumab (hand-held syringe or SID) or vice versa did not impact the known safety profile of trastuzumab. Copyright © 2017 Elsevier Ltd.

  15. Subcutaneous and Sublingual Immunotherapy in a Mouse Model of Allergic Asthma.

    Hesse, Laura; Nawijn, Martijn C

    2017-01-01

    Allergic asthma, caused by inhaled allergens such as house dust mite or grass pollen, is characterized by reversible airway obstruction, associated with an eosinophilic inflammation of the airways, as well as airway hyper responsiveness and remodeling. The inhaled allergens trigger a type-2 inflammatory response with involvement of innate lymphoid cells (ILC2) and Th2 cells, resulting in high production of immunoglobulin E (IgE) antibodies. Consequently, renewed allergen exposure results in a classic allergic response with a distinct early and late phase, both resulting in bronchoconstriction and shortness of breath. Allergen specific immunotherapy (AIT) is the only treatment that is capable of modifying the immunological process underlying allergic responses including allergic asthma and both subcutaneous AIT (SCIT) as well as sublingual AIT (SLIT) have proven clinical efficacy in long term suppression of the allergic response. Although these treatments are very successful for rhinitis, application of AIT in asthma is hampered by variable efficacy, long duration of treatment, and the risk of severe side-effects. A more profound understanding of the mechanisms by which AIT achieves tolerance to allergens in sensitized individuals is needed to improve its efficacy. Mouse models have been very valuable as a preclinical model to characterize the mechanisms of desensitization in AIT and to evaluate novel approaches for improved efficacy. Here, we present a rapid and reproducible mouse model for allergen-specific immunotherapy. In this model, mice are sensitized with two injections of allergen absorbed to aluminum hydroxide to induce allergic sensitization, followed by subcutaneous injections (SCIT) or sublingual administrations (SLIT) of the allergen as immunotherapy treatment. Finally, mice are challenged by three intranasal allergen administrations. We will describe the protocols as well as the most important read-out parameters including measurement of invasive lung

    Objective Phenylketonuria is an inherited disease caused by impaired activity of phenylalanine hydroxylase, the enzyme that converts phenylalanine to tyrosine, leading to accumulation of phenylalanine and subsequent neurocognitive dysfunction. A phenylalanine-restricted diet initiated early in life can ameliorate the toxic effects of phenylalanine. However, the diet is onerous and compliance is extremely difficult. Phenylalanine ammonia lyase (PAL) is a prokaryotic enzyme that converts phenylalanine to ammonia and trans-cinnamic acid. This Phase 1, multicenter clinical trial evaluated the safety, tolerability, pharmacokinetics and efficacy of rAvPAL-PEG (recombinant Anabaena variabilis PAL produced in E. coli conjugated with polyethylene glycol [PEG] to reduce immunogenicity) in reducing phenylalanine levels in subjects with phenylketonuria. Methods Single subcutaneous injections of rAvPAL-PEG in escalating doses (0·001, 0·003, 0·01, 0·03, and 0·1 mg/kg) were administered to 25 adults with phenylketonuria recruited from those attending metabolic clinics in North America whose blood phenylalanine concentrations were ≥600 μmol/L. Results The most frequently reported adverse events were injection-site reactions and dizziness. Reactions were self-limited without sequelae. During the trial, two subjects had adverse reactions to intramuscular (IM) medroxyprogesterone acetate, a drug containing polyethylene glycol as an excipient. Three subjects developed a generalized skin rash at the highest rAvPAL-PEG dose (0·1 mg/kg). Drug levels peaked ∼5 days after the injection. Treatment was effective in reducing blood phenylalanine in all five subjects receiving the highest dose (0·1 mg/kg, mean percent change of -58 from baseline), with a nadir ∼6 days after injection and inverse correlation between drug and phenylalanine concentrations in plasma. Phenylalanine concentrations returned to near-baseline levels ∼20 days after the single injection. Conclusions

    The aim of this work was to develop a method for processing ripe olives with a single NaOH treatment (lye) instead of the well-known 3 lye treatments. Olives of the Hojiblanca variety were processed according to the 2 processes and the color, firmness, flavor, and content in phenolic compounds of the final product were similar in both cases but concentration in triterpenic acids was highest in the olives from the single lye treatment. In this process the concentration of NaOH must range between 20 and 35 g/L, especially to obtain good texture when working at 20 °C. If temperature during the oxidation up to 27 °C the firmness of olives was significantly decreased. The concentration of the NaOH did not exert a high effect on the color of the final product, although firmness decreased as the strength of the lye increased. Higher contents in phenolic compounds and triterpenic acids were also found in the olives processed with the lowest NaOH concentration tested (20 g/L). This new process reduces the volume of wastewaters and energy consumption, and gives rise to a product which is richer in bioactive substances than the traditionally processed one. © 2016 Institute of Food Technologists®.

    Intensity-modulated particle therapy (IMPT) for tumors showing interfraction motion is a topic of current research. The purpose of this work is to compare three treatment strategies for IMPT to determine potential advantages and disadvantages of ion prostate cancer therapy. Simulations for three treatment strategies, conventional one-plan radiotherapy (ConvRT), image-guided radiotherapy (IGRT), and online adaptive radiotherapy (ART) were performed employing a dataset of 10 prostate cancer patients with six CT scans taken at one week intervals. The simulation results, using a geometric margin concept (7-2 mm) as well as patient-specific internal target volume definitions for IMPT were analyzed by target coverage and exposure of critical structures on single fraction dose distributions. All strategies led to clinically acceptable target coverage in patients exhibiting small prostate motion (mean displacement < 4 mm), but IGRT and especially ART led to significant sparing of the rectum. In 20 % of the patients, prostate motion exceeded 4 mm causing insufficient target coverage for ConvRT (V95 mean = 0.86, range 0.63-0.99) and IGRT (V95 mean = 0.91, range 0.68-1.00), while ART maintained acceptable target coverage. IMPT of prostate cancer demands consideration of rectal sparing and adaptive treatment replanning for patients exhibiting large prostate motion. (orig.) [de

    2016-02-01

    Full Text Available The subcutaneous implantable cardioverter-defibrillator (ICD is a novel technology using a subcutaneous (extrathoracic system for treatment of potential lethal ventricular arrhythmias. It avoids many of the risks of transvenous ICD implantation. It may be considered in patients having an ICD indication who do not have a pacing and/or cardiac resynchronization therapy indication, and who are unlikely to benefit from antitachycardia pacing therapy. We review patient selection, system components, the implantation technique, and screening considerations for subcutaneous ICD implantation. Its uses in specific patient populations, including children, patients with congenital heart disease, hypertrophic cardiomyopathy, or end-stage renal disease, and patients with preexisting pacemakers, are highlighted. Areas of future investigation are reviewed, including potential use with leadless pacing and magnetic resonance imaging.

    Chordoma is a radioresistant tumor that presents a therapeutic challenge with spine involvement, as high doses of radiation are needed for local control while limiting dose to the spinal cord. The purpose of this study is to determine the efficacy and safety of single-fraction spine stereotactic body radiation therapy for the treatment of spine chordoma. A retrospective review of our institutional database from 2006 to 2013 identified 8 patients (12 cases) with chordoma of the spine who were treated with spine stereotactic body radiation therapy. Surgical resection was performed in 7 of the 12 cases. The treatment volume was defined by the bony vertebral level of the tumor along with soft tissue extension appreciated on magnetic resonance imaging fusion. Medical records and imaging were assessed for pain relief and local control. Treatment toxicity was evaluated using Common Terminology Criteria for Adverse Events version 4.0. Median age was 59 years (range, 17-91). Median target volume was 48 cm 3 (1-304), and median prescription dose was 16 Gy (11-16). Median conformality index was 1.44 (1.14-3.21), and homogeneity index was 1.12 (1.05-1.19). With a median follow-up time of 9.7 months (.5-84), local control was achieved in 75% of the cases treated. One patient developed limited grade 2 spinal cord myelopathy that resolved with steroids. There were no other treatment toxicities from spine stereotactic body radiation therapy. Single-fraction spine stereotactic body radiation therapy can be safely delivered to treat chordoma of the spine with the potential to improve pain symptoms. Although the early data are suggestive, long-term follow-up with more patients is necessary to determine the efficacy of spine stereotactic body radiation therapy in the treatment of chordoma of the spine.

  7. Mortality among patients with ankylosing spondylitis after a single treatment course with x-rays

    Court Brown and Doll identified over 14,000 patients with ankylosing spondylitis who had been treated with one or more courses of x-irradiation from 1935 to 1954 at one of 87 radiotherapy centers in Great Britain and Northern Ireland. The first reports from this study analyzed mortality among these patients from leukemia and other causes, particularly cancer, but these analyses included many patients who had been treated with x-rays for their spondylitis more than once. This complicated the interpretation of the late effects of the treatment on mortality, as it was not clear to what extent the subsequent treatments contributed to the excess of deaths that persisted for many years after the first treatment. Smith and Doll (1982) avoided this difficulty by examining the death rate from leukemia and other radiation-induced cancers at different times after a single course of treatment. A comparison of the mortality of this group with the mortality of Japanese atomic bomb survivors revealed good agreement between the two studies, thus increasing confidence in the belief that both studies are giving sensible estimates of the risk of cancer from high doses of radiation. The follow-up of those spondylitic patients who received a single course of treatment only has recently been extended until the end of 1982, that is, for an additional 13 years. A further 1406 patients are now known to have died, including an additional 335 deaths for which the certified cause is cancer. Detailed results of this further follow-up will be presented

    We present a single-centre experience of procedural complications suffered by patients undergoing endovascular treatment for a ruptured saccular intracranial aneurysm at Tampere University Hospital, Finland, between 2000 and 2014. From 2000 to 2014, we treated 1,253 patients with aneurysmal subarachnoid haemorrhage, 491 of whom received endovascular treatment. Clinical data were collected retrospectively from the hospital's aneurysm database. A procedural complication was defined as having occurred whenever there was a documented new event in the patient's medical records or a note of a technical complication written by an interventionist after endovascular treatment. Procedural complications could be with or without clinical symptoms. Nearly 40% (491/1253) of the patients were treated with the endovascular method. Procedural complications occurred in 11.4% (56/491) of cases. The morbidity rate was 4.5% (22/491) and the mortality rate was 0.2% (1/491). Of the 56 complications, ischaemic complications occurred in 52% (29/56), haemorrhagic complications occurred in 27% (15/56) and technical complications occurred in 21% (12/56) of cases. In 61% (34/56) of the cases, the procedural complication did not cause any clinical symptoms. The total risk for procedural complications leading to postoperative disability or death at our institute was 4.7%. The complication frequency is in accordance with previous reports. Endovascular treatment of ruptured intracranial aneurysms is a safe treatment method when patient selection is carefully performed.

  9. Mortality among patients with ankylosing spondylitis after a single treatment course with x-rays

    1982-01-01

    Mortality was studied in 14,111 patients with ankylosing spondylitis given a single course of x-ray treatment during 1935-54. Mortality from all causes was 66% greater than that of the general population of England and Wales. The substantial excesses of deaths from non-neoplastic conditions appeared to be associated with the disease itself rather than its treatment. A nearly fivefold excess of deaths from leukaemia and a 62% excess of deaths from cancers of sites that would have been in the radiation fields (''heavily irradiated sites'') were likely to have been a direct consequence of radiation treatment. Excess death rate from leukaemia was greatest three to five years after treatment and close to zero after 18 years. Excess of cancers of heavily irradiated sites did not become apparent until nine or more years after irradiation continuing for a further 11 years. More than 20 years after irradiation the excess risk declined but the fall was not statistically significant. The number of cancers of sites not considered to be in the radiation beams was 20% greater than expected. This excess, although not statistically significant, may have been due to scattered radiation. The risk of a radiation-induced leukaemia or other cancer was related to age at treatment time.

    In order to assess the usefulness of thallium-201 single-photon emission tomography (SPET) in the treatment follow-up of nasopharyngeal carcinoma (NPC), a total of 75 {sup 201}Tl SPET studies were performed in 18 patients with histologically proven NPC. The findings were compared with those of magnetic resonance imaging (MRI) before and after therapy. Four patients received radiotherapy alone while the other 14 received concurrent chemo-radiotherapy. Treatment response was classified as complete (CR) or partial (PR) based on the findings of MRI and {sup 201}Tl SPET. Intense {sup 201}Tl uptake by the tumour was seen in all 18 patients before treatment. After treatment, MRI showed seven CRs and 11 PRs, whereas {sup 201}Tl SPET showed 13 CRs and five PRs. In 12 patients, the results of {sup 201}Tl SPET were in agreement with those of MRI. In six patients MRI showed PR but {sup 201}Tl showed CR. Follow-up (mean 10.6 months) MRI and {sup 201}Tl SPET studies of these six patients revealed that tumour gradually decreased and finally vanished in three patients. This preliminary study indicates that {sup 201}Tl SPET has potential in the assessment of early response to treatment of patients with NPC when compared with MRI. (orig.)

    We treated gonococcal urethritis in men with a single 2 g dose of azithromycin extended-release formulation (azithromycin-SR) to determine its microbiological outcomes and tolerability. We enrolled 189 Japanese men with gonococcal urethritis between April 2009 and December 2013. The patients were given a single 2 g dose of azithromycin-SR. Microbiological efficacy was evaluated by the results of the post-treatment molecular testing of Neisseria gonorrhoeae. MIC testing was performed only for pretreatment isolates of N. gonorrhoeae collected from the patients. We evaluated 130 patients for microbiological outcomes. Of these patients, 122 (93.8%) were judged to be microbiologically cured on the basis of negative test results. All isolates for which the azithromycin MICs were ≤0.25 mg/L were eradicated, whereas 5 of 12 isolates for which the MICs were 1 mg/L persisted after the treatment. Forty-six adverse events occurred in 41 patients. However, all adverse events were classified as mild. The eradication rate of N. gonorrhoeae was 93.8% in men with gonococcal urethritis treated with a single 2 g dose of azithromycin-SR. The breakpoint MIC of a 2 g dose of azithromycin-SR for gonococcal urethritis associated with clinical treatment failures appeared to be 1 mg/L. With regard to side effects of higher doses of azithromycin, the 2 g dose of azithromycin-SR appeared to improve tolerability. However, the widespread use of a high-dose regimen of azithromycin might lead to the development of further resistance to azithromycin. © The Author 2014.

    Dai, Yuxin; Zhang, Guorui; Zhu, Lan; Lang, Jinghe; Liu, Zhufeng

    To evaluate an alternative monitoring protocol without day 4 β-human chorionic gonadotropin (β-hCG) measurement for predicting the need for a repeated methotrexate (MTX) dose in patients undergoing single-dose MTX therapy for ectopic pregnancy (EP). Single-center retrospective study (Canadian Task Force classification II-3). University-affiliated hospital. Included in the study were 184 EP patients treated with MTX between January 2009 and December 2016. Single-dose MTX treatment (50 mg/m 2 ). The patients were treated with repeated doses of MTX every 7 days, if necessary, according to Stovall's protocol, or with laparoscopic surgery in cases of tubal rupture. The success of a single-dose of MTX according to the alternative measure was defined as a >50% decrease in the β-hCG level between days 1 and 7 in clinically stable patients. The sensitivity, specificity, false-negative rate, false-positive rate, and attributable risk of this new monitoring measure were calculated and compared with the traditional regimen. The new protocol had a sensitivity and specificity of 100% and 88.7%, respectively, for predicting a required second dose in patients whose day 1 β-hCG levels were <2000 mIU/mL. For patients with day 1 β-hCG level ≥2000 mIU/mL, both monitoring regimens had the same efficiency. The new monitoring model without the day 4 β-hCG measurement may offer both patients and clinicians multiple options to monitor single-dose MTX therapy for selected EP patients, with a comparable clinical efficiency to Stovall's protocol and less expense and follow-up burden to patients.

  14. Kinetics of subcutaneous NPH insulin in diabetics

    Energy Technology Data Exchange (ETDEWEB)

    Kolendorf, K.; Bojsen, J.

    1982-04-01

    Kinetics of subcutaneous NPH insulin were studied in newly diagnosed insulin-dependent diabetics. Using a biotelemetric technique with small Geiger-Mueller detectors applied to the skin surface, the disappearance of 125I-NPH insulin fron subcutis was monoexponential with a mean half-life of 6.6 +/- 3.3 (SD) hr. A model is presented to compare the disappearance rates of subcutaneous 125I-NPH insulin and the calculated plasma appearance insulin curve derived from the actual plasma insulin concentration measurements, assuming a one-compartment model and first-order kinetics. Areas under the absorption- and appearance-time curves calculated from external measurements and from plasma insulin concentrations were identical. There was a strong correlation between plasma concentrations and absorbed amounts of labeled insulin (r . 0.8782, P less than 0.001), as there was between the blood glucose-lowering effects and percent absorbed insulin per hour (r . 0.7659, P less than 0.001). Our results indicate that the disappearance rate of iodine-labeled insulin was a relevant biological expression of insulin absorption from subcutis and a reliable noninvasive method of quantitative determination of insulin concentration in blood.

    Research has confirmed the effectiveness of medications, when used in conjunction with ongoing counseling, to treat substance abuse disorders. This article describes a national, mixed-methods research project designed to investigate single state authorities’ (SSAs) perceptions of adoption of evidence-based practices in substance abuse treatment. Results are focused specifically on medication-assisted treatment, one of five evidence-based practices defined by the National Quality Forum. Medication-assisted treatment (MAT) is an important and effective part of comprehensive care options available to clients who are chronically ill with alcohol and other drug disorders. Despite mounting clinical evidence and increased availability, overall rates of implementation and sustained adoption of medications to treat addiction remain limited. The results illustrate that the SSA representatives who fund public treatment programs believe MAT is a priority and worthy of system-wide implementation. Current strategies utilized by SSAs to support the adoption of MAT are detailed, as are barriers to adoption and implementation. PMID:21138199

  16. Formula to estimate the thermal enhancement ratio of a single simultaneous hyperthermia and radiation treatment

    1984-01-01

    An experimental model composed of a C 3 H mammary carcinoma and its surrounding skin has been exposed to simultaneous radiation and hyperthermia given with different combinations of the heating time and temperature. Based on the thermal enhancement ratio (TER) values obtained in the temperature range 41.5 to 43.5 0 C, a linear relationship between TER and the heating time was achieved at each temperature. The slopes of the curves drawn at each temperature were found to have a log-linear relationship with the treatment temperature. With these relationships it was possible to make a formula expressing the TER as a function of treatment temperature and time. This formula gives a crude but probably acceptable estimate of the TER following a single simultaneous radiation and heat treatment. Although subject to several limitations, the formula represents an attempt to describe a heat dose concept for the radiosensitizing effect of hyperthermia. This may be useful to establish the tolerance level of a given radiation treatment when combined with hyperthermia. (Auth.)

    Full Text Available This review presents up-to-date understanding of immunotherapy in the treatment of children with allergic asthma. The principal types of allergen immunotherapy (AIT are subcutaneous immunotherapy (SCIT and sublingual immunotherapy (SLIT. Both of them are indicated for patients with allergic rhinitis and/or asthma, who have evidence of clinically relevant allergen-specific IgE, and significant symptoms despite reasonable avoidance measures and/or maximal medical therapy. Studies have shown a significant decrease in asthma symptom scores and in the use of rescue medication, and a preventive effect on asthma onset. Although the safety profile of SLIT appears to be better than SCIT, the results of some studies and meta-analyses suggest that the efficacy of SCIT is better and that SCIT has an earlier onset than SLIT in children with allergic asthma. Severe, not controlled asthma, and medical error were the most frequent causes of SCIT-induced adverse events.

    Sacroiliac joint pain can be managed by intra-articular injections or radiofrequency of its innervation. Single strip lesions radiofrequency denervation is a new system. The objective of this study was to present one of the first utilizations of this innovative technique. 60 patients who met the diagnostic criteria for sacroiliac joint syndrome were enrolled in the study. In total, 102 single strip lesions radiofrequency denervations were performed. Pain intensity was measured with the Oswestry low back pain disability questionnaire and the Oswestry Disability Index whose scores were assessed at 1, 3, 6 and 12 months after the procedure. 91.8 % of the 102 radiofrequency treatments resulted in a reduction of more than 50% pain intensity relief at 1 month, 81.6% at 3 months and 59.16% at 6 months. In 35.7% of cases, the relief was continuative up to 1 year. No relief was observed in 12.24% of cases. The ODI scores improved significantly 1 month after the procedure, compared with the baseline scores. The ODI scores after 6 months improved very clearly compared with the baseline scores and with the 3-month scores. Single strip lesions radiofrequency denervation using the Simplicity III probe is a potential modality for intermediate term relief for patients with sacroiliac pain.

    Study Design Retrospective cohort study. Purpose Trauma is the most common cause for chronic coccygodynia. The present study aims at presenting our results after complete removal of the coccyx for refractory traumatic coccygodynia in terms of pain level, complication rates, and patients' overall satisfaction. Overview of Literature There is limited extant literature describing the success rate and complications in refractory isolated traumatic coccygodynia. Methods From January 2011 to January 2012, 10 consecutive patients with posttraumatic coccygodynia (six males and four females; mean age, 42 years) were enrolled in our study. Conservative treatment of the condition had failed in all patients. The same surgeon performed a complete coccygectomy on all patients. Postoperative outcomes included measurements of pain relief and degree of patient satisfaction with the procedure's results. Results In our selected cohort, all patients indicated complete pain relief or significant pain improvement in follow up-care and would recommend this procedure. One patient developed a subcutaneous hematoma that required surgical intervention. Conclusions Our results suggest that complete removal of the coccyx relieves pain in patients with refractory chronic traumatic coccygodyniaand is therefore a reasonable treatment option after conservative treatment failure.

    The aim of this study was to analyze the patterns of care and treatment outcomes in patients with primary thyroid lymphoma (PTL) in a single institution. Medical records of 29 patients with PTL treated between April 1994 and February 2012 were retrospectively reviewed. Diagnosis was confirmed by biopsy (n = 17) or thyroidectomy (n = 12). Treatment modality and outcome were analyzed according to lymphoma grade. The median follow-up was 43.2 months (range, 3.8 to 220.8 months). The median age at diagnosis was 57 years (range, 21 to 83 years) and 24 (82.8%) patients were female. Twenty-five (86.2%) patients had PTL with stage IEA and IIEA. There were 8 (27.6%) patients with mucosa-associated lymphoid tissue (MALT) lymphoma and the remaining patients had high-grade lymphoma. Patients were treated with surgery (n = 2), chemotherapy (n = 7), radiotherapy (n = 3) alone, or a combination of these methods (n = 17). Treatment modalities evolved over time and a combination of modalities was preferred, especially for the treatment of high-grade lymphoma in recent years. There was no death or relapse among MALT lymphoma patients. Among high-grade lymphoma patients, 5-year overall survival (OS) and 5-year progression-free survival (PFS) were 75.6% and 73.9%, respectively. Complete remission after initial treatment was the only significant prognostic factor for OS (p = 0.037) and PFS (p = 0.003). Patients with PTL showed a favorable outcome, especially with MALT lymphoma. Radiotherapy alone for MALT lymphoma and chemotherapy followed by radiotherapy for high-grade lymphoma can be effective treatment options for PTL.

  2. Recurrent subcutaneous emphysema of the face: a challenging clinical problem.

    In the neck or face, there are different causes for subcutaneous emphysema such as injury to the sinuses, the hypopharynx, the laryngotracheal complex, the pulmonary parenchyma, the esophagus or the presence of gas-forming organisms. However, factitious subcutaneous emphysema, a rare cause, must be considered in the differential diagnosis. In this clinical report, we discuss a 20-year-old girl who was under follow-up because of recurrent subcutaneous emphysema of the face and periorbital area. After 2 years of work-ups, including a period of close observation in the intensive care unit, self air injection by syringe was found as the cause of recurrent subcutaneous emphysema of the face, and the patient was labeled as having factitious recurrent subcutaneous emphysema. Therefore, when a patient presents with unexplained recurrent subcutaneous emphysema, one should suspect self-infliction and examine for puncture marks.

    Full Text Available Background Tight control of severe rheumatoid arthritis (RA in patients with high disease activity, even when using biologics, is sometimes difficult using a treat-to-target strategy. Switching from one biologic to another is associated with lower efficacy than that in treatment-naive cases. We developed the K-method that involves simultaneous treatment with golimumab and intra-articular joint injection of triamcinolone acetonide (TA in patients undergoing switching of biologics. We performed this retrospective case–control study to investigate the efficacy of achieving an immediate treatment response using the K-method. Methods This study involved 20 patients with RA (control group, 10 patients; K-method group, 10 patients. Patients in the control group were switched to golimumab from other biologics without intra-articular injection of TA. The K-method involved injection of 1 mL of TA (40 mg/mL and 2 mL of 1% lidocaine hydrochloride into swollen or painful joints on the same day as golimumab treatment. A quick response one day after treatment was compared between the two groups according to the disease activity score 28 based on C-reactive protein (DAS28 CRP, clinical disease activity index (CDAI, simplified disease activity index (SDAI, European League Against Rheumatism (EULAR response, and remission rate. These parameters were investigated for 24 weeks. Results The K-method group showed significant improvements in DAS28 CRP, CDAI, and SDAI at one day, 12 weeks, and 24 weeks compared with the control group. The number of swollen and tender joints and the patient and doctor global visual analog scale scores were also significantly different between the two groups. The remission rates based on DAS28 CRP were 30% at one day, 50% at 12 weeks, and 60% at 24 weeks in the K-method group. The EULAR good/moderate response rates were 80% at one day, 90% at 12 weeks, and 90% at 24 weeks in the K-method group; however, these rates were only 10%, 40

    Allergen-specific immunotherapy is the only causal form of therapy for IgE-mediated allergic diseases. Subcutaneous immunotherapy (SCIT) is considered safe and well tolerated in adults, yet there is less evidence of safety in the pediatric population. A non-interventional prospective observing longitudinal study was carried out to determine the incidence of local and systemic side effects by SCIT, routinely performed in pediatric patients. A total of 581 pediatric patients were observed in 18 study centers between March 2012 and October 2014, recording 8640 treatments and 10 015 injections. A total of 54.6% of the patients experienced immediate local side effects at least once; delayed local side effects were seen in 56.1%. Immediate systemic adverse reactions occurred in 2.2% of patients; 7.4% experienced delayed systemic side effects. However, severe systemic side effects (grade III in the classification of Ring and Messmer) were seen in 0.03% of all treatments, all appearing within 30 minutes after the injections. No grade IV reactions were observed. In addition, many potential risk factors were investigated, yet only a few were found to be associated with the occurrence of side effects. Subcutaneous immunotherapy is a safe form of therapy in pediatric patients, with similar rates of local side effects compared to adult patients and low rates of severe systemic side effects. However, local and systemic reactions occurring later than 30 minutes after injection were observed more often than expected, which makes it essential to be attentive on behalf of pediatricians, patients, and parents. © 2017 EAACI and John Wiley and Sons A/S.

    IL-23 is associated with plaque psoriasis susceptibility and pathogenesis. BI 655066 is a fully human IgG1 mAb specific for the IL-23 p19 subunit. This first-in-human proof-of-concept study evaluated the clinical and biological effects of BI 655066 in patients with moderate-to-severe plaque psoriasis. We performed a single-rising-dose, multicenter, randomized, double-blind, placebo-controlled, within-dose cohort phase I trial. Patients received 0.01, 0.05, 0.25, 1, 3, or 5 mg/kg BI 655066 intravenously, 0.25 or 1 mg/kg BI 655066 subcutaneously, or matched placebo. The primary objective was safety evaluation. Thirty-nine patients received single-dose BI 655066 intravenously (n = 18) or subcutaneously (n = 13) or placebo (n = 8). Adverse events were reported with similar frequency in the BI 655066 and placebo groups. Four serious adverse events (not considered treatment related) were reported among BI 655066-treated patients. BI 655066 was associated with clinical improvement from week 2 and maintained for up to 66 weeks after treatment. At week 12, 75%, 90%, and 100% decreases in the Psoriasis Area and Severity Index were achieved by 87%, 58%, and 16% of BI 655066-treated patients (any dose), respectively, versus none receiving placebo. BI 655066 treatment resulted in reduced expression of lesional skin genes associated with IL-23/IL-17 signaling pathways and normalization of psoriatic lesion gene expression profiles to a profile approaching that of nonlesional skin. Significant correlation between treatment-associated molecular changes and psoriasis area and severity index improvement was observed (r = 0.73, P = 2 × 10(-6)). BI 655066 was well tolerated and associated with rapid, substantial, and durable clinical improvement in patients with moderate-to-severe psoriasis, supporting a central role for IL-23 in psoriasis pathogenesis.

    An extensive survey of parasites in red foxes (Vulpes vulpes) was independently conducted in Romania and the Czech Republic. Carcasses were examined by necropsy, and small, dark nodules apparently containing ticks were noticed in the subcutaneous tissue of several foxes. Histopathological examination was performed using hematoxylin and eosin (HE) staining. Of the 91 foxes examined from the Czech Republic, 14 (15.4%) were harboring ticks in the subcutaneous tissue. In the majority of these cases, 1-3 nodules/fox were found, with a maximum of 31 nodules/fox. In Romania a single examined fox had subcutaneous ticks. All ticks collected from subcutaneous tissue were partially engorged adults. Based on morphological features, Ixodes ricinus, I. hexagonus, I. crenulatus and Dermacentor reticulatus were identified. The histopathological examination revealed chronic granulomatous panniculitis with peripheral fibrosis and intralesional presence of the ticks. Only few data are available regarding ticks localized in the subcutaneous tissue of any host. All the ticks were dead or already decomposed and it is evident that subcutaneous location does not represent an evolutionary advantage, as the detachment and finishing the life cycle is impossible.

    Full Text Available Abstract Background Our recent investigations have demonstrated that cell cultures from subjects, who received a single spinal manipulative treatment in the upper thoracic spine, show increased capacity for the production of the key immunoregulatory cytokine, interleukin-2. However, it has not been determined if such changes influence the response of the immune effector cells. Thus, the purpose of the present study was to determine whether, in the same subjects, spinal manipulation-related augmentation of the in vitro interleukin-2 synthesis is associated with the modulation of interleukin 2-dependent and/or interleukin-2-induced humoral immune response (antibody synthesis. Methods A total of seventy-four age and sex-matched healthy asymptomatic subjects were studied. The subjects were assigned randomly to: venipuncture control (n = 22, spinal manipulative treatment without cavitation (n = 25 or spinal manipulative treatment associated with cavitation (n = 27 groups. Heparinized blood samples were obtained from the subjects before (baseline and then at 20 minutes and 2 hours post-treatment. Immunoglobulin (antibody synthesis was induced in cultures of peripheral blood mononuclear cells by stimulation with conventional pokeweed mitogen or by application of human recombinant interleukin-2. Determinations of the levels of immunoglobulin G and immunoglobulin M production in culture supernatants were performed by specific immunoassays. Results The baseline levels of immunoglobulin synthesis induced by pokeweed mitogen or human recombinant interleukin-2 stimulation were comparable in all groups. No significant changes in the production of pokeweed mitogen-induced immunoglobulins were observed during the post-treatment period in any of the study groups. In contrast, the production of interleukin-2 -induced immunoglobulin G and immunoglobulin M was significantly increased in cultures from subjects treated with spinal manipulation. At 20 min post

    Subcutaneous allergen immunotherapy (SCIT) and sublingual allergen immunotherapy (SLIT) are safe and effective treatments of allergic rhinitis, but high levels of compliance and persistence are crucial to achieving the desired clinical effects. Our objective was to assess levels and predictors of compliance and persistence among grass pollen, tree pollen, and house dust mite immunotherapy users in real life and to estimate the costs of premature discontinuation. We performed a retrospective analysis of a community pharmacy database from The Netherlands containing data from 6486 patients starting immunotherapy for 1 or more of the allergens of interest between 1994 and 2009. Two thousand seven hundred ninety-six patients received SCIT, and 3690 received SLIT. Time to treatment discontinuation was analyzed and included Cox proportional hazard models with time-dependent covariates, where appropriate. Overall, only 18% of users reached the minimally required duration of treatment of 3 years (SCIT, 23%; SLIT, 7%). Median durations for SCIT and SLIT users were 1.7 and 0.6 years, respectively (P < .001). Other independent predictors of premature discontinuation were prescriber, with patients of general practitioners demonstrating longer persistence than those of allergologists and other medical specialists; single-allergen immunotherapy, lower socioeconomic status; and younger age. Of the persistent patients, 56% were never late in picking up their medication from the pharmacy. Direct medication costs per nonpersistent patient discontinuing in the third year of treatment were €3800, an amount that was largely misspent. Real-life persistence is better in SCIT users than in SLIT users, although it is low overall. There is an urgent need for further identification of potential barriers and measures that will enhance persistence and compliance. Copyright © 2013 American Academy of Allergy, Asthma & Immunology.

    Spinal cord stimulation as treatment of chronic low back pain via neuromodulation has been frequently performed in recent years. The dorsal column is stimulated by an electrode placed at the epidural region. In the case presently described, subcutaneous lead was implanted in a patient with failed back syndrome after spinal cord stimulation was inadequate to treat back and gluteal pain. A 65-year-old male had undergone surgery to treat lumbar disc herniation, after which he received physical therapy and multiple steroid injections due to unrelieved pain. He was admitted to the pain clinic with pain radiating to right gluteal muscle and leg. Spinal cord stimulation was performed and, as pain was not relieved, subcutaneous lead was applied to the right cluneal nerve distribution. Following treatment, the patient scored 1-2 on visual analog scale. Pain had been reduced by over 80%. Octad electrode was placed between T8 and T10 vertebrae after Tuohy needle was introduced to intervertebral area between L1 and L2. Paresthesia occurred in the right extremity. Boundaries were determined by area of right gluteal region in which paresthesia did not occur. Octad electrode was placed subcutaneously after vertical line was drawn from center point. Paresthesia occurred throughout the region. Pulse wave was 390-450 msec; frequency was 10-30 Hz. Subcutaneous electrode replacement is effective additional therapy when pain is not relieved by spinal cord stimulation.

    Today, different kinds of non-invasive body contouring modalities, including cryolipolysis, radiofrequency (RF), low-level laser therapy (LLLT), and high-intensity focused ultrasound (HIFU) are available for reducing the volume of subcutaneous adipose tissue or cellulite. Each procedure has distinct mechanisms for stimulating apoptosis or necrosis adipose tissue. In addition to the mentioned techniques, some investigations are underway for analyzing the efficacy of other techniques such as whole body vibration (WBV) and extracorporeal shockwave therapy (ESWT). In the present review the mechanisms, effects and side effects of the mentioned methods have been discussed. The effect of these devices on cellulite or subcutaneous fat reduction has been assessed. We searched pubmed, google scholar and the cochrane databases for systemic reviews, review articles, meta-analysis and randomized clinical trials up to February 2015. The keywords were subcutaneous fat, cellulite, obesity, noninvasive body contouring, cryolipolysis, RF, LLLT, HIFU, ESWT and WBV with full names and abbreviations. We included seven reviews and 66 original articles in the present narrative review. Most of them were applied on normal weight or overweight participants (body mass index cellulite in some body areas. However, the clinical effects are mild to moderate, for example 2 - 4 cm circumference reduction as a sign of subcutaneous fat reduction during total treatment sessions. Overall, there is no definitive noninvasive treatment method for cellulite. Additionally, due to the methodological differences in the existing evidence, comparing the techniques is difficult.

    Full Text Available Single tablet regimens (STRs for HIV infection improve patient satisfaction, quality of life, medication adherence, and virological suppression compared to multitablet regimens (MTRs. This is the first study assessing STR uptake and durability in Australia. This retrospective audit of all patients receiving an STR (n=299 at a large Sydney HIV clinic (January 2012–December 2013 assessed patient demographics, treatment prior to STR, HIV RNA load and CD4 during MTR and STR dosing, and reasons for STR switch. 206 patients switched from previous antiretroviral treatment to an STR, of which 88% switched from an MTR. Reasons for switching included desire to simplify treatment (57%, reduced side effects or toxicity (18%, and cost-saving for the patient. There was no switching for virological failure. Compared to when on an MTR, patients switching to an STR had significantly lower HIV RNA counts (p<0.001 and significantly higher CD4 counts (p<0.001. The discontinuation rate from STR was very low and all patients who switched to an STR maintained virological suppression throughout the study duration, although the study is limited by the absence of a control group.

  15. Subcutaneous NPH Insulin for Severe Hypertriglyceridemia in a Pregnant Patient with Type V Hyperlipoproteinemia: a Case Report

    Directory of Open Access Journals (Sweden)

    Mustafa Kemal Balcı

    2012-06-01

    Full Text Available An increase in triglyceride levels in familial hyperlipidemia during pregnancy has been reported. Severe hypertriglyceridemia can lead to complications such as acute pancreatitis, preeclampsia, maternal and fetal complications. Because of the teratogenic effects associated with fibrate therapy in pregnancy, alternative treatment strategies such as insulin as a rapid and potent activator of lipoprotein lipase are required during pregnancy. We report a case of hypertriglyceridemia in a 33-year-old pregnant woman in whom treatment with merely single one time administration of Neutral Protamine Hagedorn insulin was accompanied by a reduction in the serum triglyceride level; to the best of our knowledge, this has never been reported in the literature. Her triglyceride level was 3616 mg/dL before insulin treatment and 1246 mg/dL after insulin treatment. Although this regimen was used safely and effectively in our patient, comprehensive studies are required to evaluate the effectiveness and safety of subcutaneously intermediate-acting Neutral Protamine Hagedorn insulin for the treatment of severe hypertriglyceridemia in non-diabetic pregnant women.

    2016-01-01

    Cumulative recent evidence from clinical trials, observational studies and case reports has shown that subcutaneous administration of immunoglobulin (SCIg) exerts similar immunomodulatory capacity than intravenous immunoglobulin (IVIg) in autoimmune neurological diseases. Besides the beneficial clinical effects, the profile of safety and autonomy for the patient is higher for SCIg, while it is cost-saving in terms of the health resources used. However, there are still very few approved indications for SCIg and a certain resistance to choose SCIg for other autoimmune conditions even despite patients' interests. Here we present an updated review of the known immunomodulatory mechanisms of action of Ig and the current hypothesis supporting the clinical and immunological advantages of SCIg over IVIg that derive from their specific pharmacokinetic features.

    Haemophilus ducreyi (HD) and Treponema pallidum subspecies pertenue (TP) are major causative agents of cutaneous ulcer (CU) in the tropics. Azithromycin is recommended to treat sexually transmitted HD infections and has good in vitro activity against HD strains from both genital and skin ulcers. We investigated the efficacy of oral single-dose azithromycin on HD-CU. We conducted a community-based cohort study in Lihir Island, Papua New Guinea, from October 2014 through May 2016. Consenting patients with skin ulcers >1 cm in diameter were eligible for this study and had collected a lesional swab for polymerase chain reaction (PCR). All participants were treated with single-dose azithromycin (30 mg/kg) and were followed up for assessment of clinical resolution. We retrospectively classified patients according to PCR results into HD, TP, and PCR-negative groups. The primary endpoint was healing rates of HD-CU at 14 days after treatment. We obtained full outcome data from 246 patients; 131 (53.3%) were HD PCR positive, 37 (15.0%) were TP positive, and 78 (31.7%) were negative for all tests. Healing rates were 88.5% (95% confidence interval [CI], .82-.93) in the HD group, 78.4% [95% CI, .63-.89] in the TP group, and 74.4% (95% CI, .64-.83) in the PCR-negative group. If we included the participants with improved ulcers, the healing rates increased to 94.7%, 97.3%, and 89.7% respectively. HD cases classified as not healed all converted to HD-negative PCR. Based upon clinical resolution and PCR conversion to HD negative, a single oral dose of azithromycin is efficacious for the treatment of HD-CU. These results have implications for the treatment of individual patients and for the use of antibiotics in public health strategies to control CU in the tropics. © The Author 2017.

    To determine the plasma disposition of meloxicam in goats following S/C, oral or I/V administration at a single dose of 0.5 mg/kg bodyweight. Five healthy Saanen goats, aged 12-14 months and weighing 35-40 kg, were used for a three phase cross-over design with a 10-day washout period, with meloxicam administered I/V, then orally and S/C. Heparinised blood samples (5 mL) were collected from all animals prior to drug administration (0 hours) and subsequently up to 96 hours. Concentrations of meloxicam in plasma were measured using high performance liquid chromatography. Concentration-time curves were fitted and pharmacokinetic parameters were estimated for each administration group. Subcutaneous administration of meloxicam exhibited unique plasma distribution characteristics that differed from oral and I/V administration. Mean peak plasma concentrations were greater (1.91 (SD 0.39) vs. 0.71 (SD 0.17) µg/mL) and the time to reach them shorter (3.20 (SD 1.64) vs. 14.33 (SD 2.19) hours) following S/C compared with oral administration (pmeloxicam resulted in long-term presence of drug at high concentration in goat plasma. This unique plasma disposition characteristic may offer an advantage in some clinical cases towards potentially improving the treatment efficacy in goats.

  20. Analytical Treatment of Single Bunch Transverse Dynamics in Linacs with Wakefields

    Guignard, Gilbert

    1998-01-01

    In this paper we present an analytical treatment of the equation of motion of single bunch particles traveling in the linac of a linear collider, in the presence of wakefields. Using a somewhat simplified model, the equation is solved for a Gaussian distribution of charge, a linear variation of the wakefield along the bunch, a smooth focusing and in the absence of acceleration. The specificity of the method consists of preventing the appearance of artificial secular terms and keeping at any stage the intrinsic tune-shift that characterizes the problem and stabilizes the motion. Hence, a first order perturbation becomes sufficient provided that a non-standard perturbation expansion, specially developed for this analysis, be however applied. Solutions for the particle off-sets within the bunch are obtained and their contributions to the effective emittance calculated. The results explain the observed features of beam breakup and BNS damping, and reproduce the bunch dipole-oscillations visible on the animated gr...

    Full Text Available Arc discharge is the most practical method for the synthesis of single wall carbon nanotubes (SWCNT. However, the production of SWCNT by this technique has low selectivity and yield, requiring further purification steps. This work is a study of purification of SWCNT by heat treatment in an inert atmosphere followed by supercritical fluid extraction. The raw arc discharge material was first heat-treated at 1250 °C under argon. The nanotubes were further submitted to an extraction process using supercritical CO2 as solvent. A surfactant (tributylphosphate, TBP and a chelating agent (hexafluoroacetylacetone, HFA were used together to eliminate metallic impurities from the remaining arc discharge catalysts. Analysis of Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES showed an efficient removal of iron and cobalt (>80%. The purified nanotubes were further analyzed by TGA and Raman spectroscopy.

    Lymphoma of the conjunctiva is rare. It presents in older patients as a mass lesion and usually remains localized. Surgery is limited to biopsy, and radiation therapy is the definitive treatment of choice. The entire conjunctiva is treated. Relatively high doses (approximately 30 Gy) are required for local control, which may lead to cataract formation. Twelve patients with conjunctival lymphoma were treated at the Massachusetts General Hospital between 1979 and 1988. Ten of 12 patients presented with a unilateral lesion; 2 of 12 with bilateral lesions. Two of 12 patients were found to have systemic disease at the time of presentation. One patient developed conjunctival lymphoma 5 years after the diagnosis of generalized disease. Using electron beam, all patients were treated with a single anterior circular field to total doses ranging from 24 Gy to 30 Gy delivered in 8 to 16 fractions over 9 to 20 days. In all cases, the lens was shielded by a specially designed plastic contact lens bearing a 12 mm diameter lead shield. The lens dose was determined at varying depths beneath the shield for 6 MeV and 9 MeV electron beams and ranged from a minimum of 5% to an absolute maximum of 18% of the total dose delivered to the tumor. Local control was maintained in all patients with follow-up to 9 1/2 years. One patient relapsed distantly 3 years after treatment. One of 12 patients died of systemic disease 4 years after treatment of the ocular lesion. Two patients developed cataracts 4 and 5 years after treatment; one had bilateral cataract, although only one eye had been treated. Both patients were over 75 years old. In both cases, the cataracts were felt to be senile cataracts which are ophthalmologically and radiographically distinguishable from radiation induced lesions

    Surgical treatment of chronic pancreatitis is indicated for intractable pain. Frey's procedure is an accepted treatment for this disease. The aim of the present study was to describe a single-centre experience in the treatment of chronic pancreatitis using Frey's procedure. A retrospective analysis of 73 patients who underwent a Frey's procedure between 1991 to 2007 and had at least 1 year of follow-up. Demographics, indication for surgery, peri-operative complications and late outcomes were analysed. The median age was 39.9 years. Seventy out of the 73 (95.8%) patients were male. The median pre-operative body mass index (BMI) was 19.1 kg/m(2). All patients had abdominal pain, 34 (46.6%) of them daily and 13 (17.8%) weekly, with moderate or severe intensity in 98.6% (n= 72). The aetiology was secondary to alcohol in 70 patients (95.9%), with a median consumption of 278 g per day. The surgical morbidity rate was 28.7%; there were no deaths. Median post-operative follow-up was 77.0 months; 64 patients (91.4%) had complete pain relief and post-operative BMI was 22.4 kg/m(2) (P<0.001). All patients with pre-operative endocrine and exocrine insufficiencies showed no reversal of the situation. New onset insufficiencies appeared late. Frey's procedure was a safe and effective therapeutic option for the surgical treatment of patients with intractable pain caused by chronic pancreatitis. © 2011 International Hepato-Pancreato-Biliary Association.

    Full Text Available Purpose The aim of the study was to evaluate the efficacy and safety of bilateral single-session retrograde intrarenal surgery in the treatment of bilateral renal stones. Materials and Methods From December 2008 to February 2012, 42 patients who had undergone bilateral single-session retrograde intrarenal surgery (RIRS and laser lithotripsy were included in the study. The procedures were performed in the lithotomy position on an endoscopy table under general anesthesia, beginning on the side in which the stone size was smaller. Plain abdominal radiography, intravenous urograms (IVU, renal ultrasonography (USG and / or non-contrast tomography (CT scans were conducted for all patients. The success rate was defined as patients who were stone-free or only had residual fragment less than 4 mm. Results A total of 42 patients (28 male, 14 female with a mean age 39.2 ± 14.2 were included in the present study. The mean stone size was 24.09 ± 6.37 mm with a mean operative time of 51.08 ± 15.22 minutes. The stone-free rates (SFR were 92.8% and 97.6% after the first and second procedures, respectively. The average hospital stay was 1.37 ± 0.72 days. In two patients (4.7%, minor complications (Clavien I or II were observed, whereas no major complications (Clavien III-V or blood transfusions were noted in the studied group. Conclusions Bilateral single-session RIRS and laser lithotripsy can be performed safely and effectively with a high success rate and low complication rate in patients with bilateral renal stones.

    Full Text Available Aim: The aim of this study was to evaluate the clinical and radiological results in patients with severe hallux rigidus who underwent arthrodesis using single cortical screw. Methods: We retrospectively evaluated 18 patients (16 females, 2 males who underwent arthrodesis for severe hallux rigidus using single cortical screw. The mean age of the patients was 58.1 (range: 44-69 years. According to the Coughlin and Shurnas classification, 5 feet were rated as stage 3 and 13 feet were stage 4. 3 of the stage 3 patients had cheilectomy previously. The American Orthopaedic Foot and Ankle Society (AOFAS clinical rating scale for the metatarsophalangeal - interphalangeal joints was used for clinical evaluation. Hallux valgus angles and hallux dorsiflexion angles were measured on X-rays. Results: The mean follow-up period was 32.4 (range: 15-69 months. Radiological signs of non-union was found in one patient. The mean preoperative AOFAS score was 56.1 (range: 38-72. The mean final follow-up AOFAS score was found to be 81.1. Moderate results in 2 patients (11.1%, good results in 11 patients (61.1% and excellent results in 5 patients (27.8% were obtained. When the last X-rays were evaluated, 15.1° (7-24 valgus at the metatarsophalangeal joint and 11.9° (8-18 extension (to the floor at the metatarsophalangeal joint were detected. Late surgical wound healing was observed in one patient. The screws were removed due to irritation in 8 (44% patients. Conclusion: We assume that in the treatment of severe hallux rigidus, arthrodesis using a single cortical screw may be considered as a favorable surgical technique with its high union rates and increased functional results.

    Although poorly documented, subcutaneous (SC) administration of antibiotics is common practice in France especially in Geriatrics Departments. The aim of this study was to determine the tolerance of such a practice. Prospective observational multicentre study. Sixty-six physicians accepted to participate from 50 French Infectious Diseases and Geriatrics Departments. From May to September 2014, patients treated at least one day with SC antibiotics could be included. Modalities of subcutaneous administration, occurrence of local and systemic adverse effects (AE) and clinical course were collected until the end of the treatment. Two hundred-nineteen patients (83.0 [19–104] yo) were included. Ceftriaxone (n = 163, 74.4%), and ertapenem (n = 30, 13.7%) were the most often prescribed antibiotics. The SC route was mainly used because of poor venous access (65.3%) and/or palliative care (32.4%). Fifty patients (22.8%) experienced at least one local AE that led to an increased hospital stay for two patients (4.0%) and a discontinuation of the SC infusion in six patients (12.0%). A binary logistic regression for multivariate analysis identified the class of antibiotic (p = 0.002) especially teicoplanin and the use of rigid catheter (p = 0.009) as factors independently associated with AE. In over 80% of cases, SC antibiotics were well tolerated and associated with clinical recovery. SC administration of antibiotics leads to frequent but local and mild AE. Use of non-rigid catheter appears to be protective against AE. As it appears to be a safe alternative to the intravenous route, more studies are needed regarding efficacy and pharmacokinetics.

    2015-01-01

    Full Text Available Both in vitro and in vivo experiments have confirmed that platelet-rich plasma has therapeutic effects on many neuropathies, but its effects on carpal tunnel syndrome remain poorly understood. We aimed to investigate whether single injection of platelet-rich plasma can improve the clinical symptoms of carpal tunnel syndrome. Fourteen patients presenting with median nerve injury who had suffered from mild carpal tunnel syndrome for over 3 months were included in this study. Under ultrasound guidance, 1-2 mL of platelet-rich plasma was injected into the region around the median nerve at the proximal edge of the carpal tunnel. At 1 month after single injection of platelet-rich plasma, Visual Analogue Scale results showed that pain almost disappeared in eight patients and it was obviously alleviated in three patients. Simultaneously, the disabilities of the arm, shoulder and hand questionnaire showed that upper limb function was obviously improved. In addition, no ultrasonographic manifestation of the carpal tunnel syndrome was found in five patients during ultrasonographic measurement of the width of the median nerve. During 3-month follow-up, the pain was not greatly alleviated in three patients. These findings show very encouraging mid-term outcomes regarding use of platelet-rich plasma for the treatment of carpal tunnel syndrome.

    To investigate the treatment outcomes of parotid gland cancer at a single center over a 10-year period and to evaluate the prognostic significance of maximum standardized uptake value. Retrospective case series with chart review. Academic care center. Ninety-eight patients with primary parotid gland cancer who were surgically treated at Yonsei University Head & Neck Cancer Clinic between January 1999 and December 2008 were analyzed. Patient data were collected retrospectively from medical charts. The investigators analyzed the association of clinicopathological factors and maximum standardized uptake value on (18)F-fluorodeoxyglucose positron emission tomography-computed tomography scan with disease-specific survival. Mean patient age was 49.7 years. Mean follow-up was 48.8 months. Thirty-three, 40, 30, and 23 patients had stage I, II, III, and IVA disease, respectively. Mucoepidermoid carcinoma was the most common histologic type (34.7%), followed by acinic cell carcinoma (27.6%). Eighteen patients (18.4%) experienced recurrences (mean recurrence gap, 20.6 months; range, 2-87 months). Five- and 10-year disease-specific survival rates were 93.6% and 81.8%, respectively. In the univariate analysis, pathologic T stage, pathologic lymph node status, resection margin, external parenchymal extension, and maximum standardized uptake value were significantly associated with disease-specific survival. Pathologic lymph node status and maximum standardized uptake value were independent prognostic factors in the multivariate analysis. Our single-center experience with parotid gland cancer treatment is consistent with the literature. Cervical lymph node metastasis and high maximum standardized uptake value are associated with poor survival in parotid gland cancer. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

Seventeen cases of single-segment lumbar TB were treated with single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation. The mean follow-up was 36.9 months (range: 24-62 months). The kyphotic angle ranged from 15.2-35.1° preoperatively, with an average measurement of 27.8°. The American Spinal Injury Association (ASIA) score system was used to evaluate the neurological deficits and erythrocyte sedimentation rate (ESR) used to judge the activity of TB. Spinal TB was completely cured in all 17 patients. There was no recurrent TB infection. The postoperative kyphotic angle was 6.6-10.2°, 8.1° in average, and there was no significant loss of the correction at final follow-up. Solid fusion was achieved in all cases. Neurological condition in all patients was improved after surgery. Single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation can be a feasible and effective method the in treatment of single-segment lumbar spinal TB.

    2011-01-01

    This literature review aimed to identify and assess the conservative treatment options for replacing a single missing anterior tooth, for patients who cannot afford implants or traditional bridges. The evidence was obtained using MEDLINE searches. A total of 19 studies met the inclusion criteria. None of these studies scored higher than 10 of 17, suggesting that all studies did not have strong evidence. Three of the studies examined resin-bonded bridges (RBBs), whereas the other three investigated removable partial dentures (RPDs). None of the studies had random patient selection. Three of these studies had controlled allocation of patients. The other three allowed new patients to enter the study throughout the study period. Placement of the prosthesis was only conducted in one study, whereas the rest of the studies examined patients with preexisting prostheses. In general, all 19 studies were weak due to poor study design, no acceptable controls, no direct comparison between RBBs and RPDs, lack of longitudinal studies and no differentiation between the anterior and posterior prostheses. Therefore, no definitive treatment conclusion can be made until studies of stronger design are conducted.

    Full Text Available The objectives here are to provide a systematic review of the current evidence concerning the use of Chinese herbs in the treatment of Alzheimer's disease (AD and to understand their mechanisms of action with respect to the pathophysiology of the disease. AD, characterized microscopically by deposition of amyloid plaques and formation of neurofibrillary tangles in the brain, has become the most common cause of senile dementia. The limitations of western medications have led us to explore herbal medicine. In particular, many Chinese herbs have demonstrated some interesting therapeutic properties. The following databases were searched from their inception: MEDLINE (PUBMED, ALT HEALTH WATCH (EBSCO, CINAH and Cochrane Central. Only single Chinese herbs are included. Two reviewers independently extracted the data and performed quality assessment. The quality assessment of a clinical trial is based on the Jadad criteria. Seven Chinese herbs and six randomized controlled clinical trials were identified under the predefined criteria. Ginkgo biloba, Huperzine A (Lycopodium serratum and Ginseng have been assessed for their clinical efficacy with limited favorable evidence. No serious adverse events were reported. Chinese herbs show promise in the treatment of AD in terms of their cognitive benefits and more importantly, their mechanisms of action that deal with the fundamental pathophysiology of the disease. However, the current evidence in support of their use is inconclusive or inadequate. Future research should place emphasis on herbs that can treat the root of the disease.

    Full Text Available Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months. Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

    Wastewater recycling has been and continues to be practiced all over the world for a variety of reasons including: increasing water availability, combating water shortages and drought, and supporting environmental and public health protection. Nowadays, one of the most interesting issues for wastewater recycling is the on-site treatment and reuse of grey water. During this study the efficiency of a compact Submerged Membrane Bioreactor (SMBR) system to treat real grey water in a single house in Crete, Greece, was examined. In the study, grey water was collected from a bathtub, shower and washing machine containing significant amounts of organic matter and pathogens. Chemical oxygen demand (COD) removal in the system was approximately 87%. Total suspended solids (TSS) were reduced from 95mgL(-1) in the influent to 8mgL(-1) in the effluent. The efficiency of the system to reduce anionic surfactants was about 80%. Fecal and total coliforms decreased significantly using the SMBR system due to rejection, by the membrane, used in the study. Overall, the SMBR treatment produces average effluent values that would satisfy international guidelines for indoor reuse applications such as toilet flushing. Copyright © 2016 Elsevier B.V.

    Full Text Available Biomechanical preparation of root canals with accentuated curvature is challenging. New rotatory systems, such as Reciproc, require a shorter period of time to prepare curved canals, and became a viable alternative for endodontic treatment of teeth with root dilaceration. Thus, this study aimed to report a clinical case of endodontic therapy of root with accentuated dilaceration using Reciproc single-file system. Mandibular right second molar was diagnosed as asymptomatic irreversible pulpitis. Pulp chamber access was performed, and glide path was created with #10 K-file (Dentsply Maillefer and PathFile #13, #16 and #19 (Dentsply Maillefer up to the temporary working length. The working length measured corresponded to 20 mm in the mesio-buccal and mesio-lingual canals, and 22 mm in the distal canal. The R25 file (VDW GmbH was used in all the canals for instrumentation and final preparation, followed by filling with Reciproc gutta-percha cones (VDW GmbH and AH Plus sealer (Dentsply Maillefer, using thermal compaction technique. The case has been receiving follow-up for 6 mon and no painful symptomatology or periapical lesions have been found. Despite the difficulties, the treatment could be performed in a shorter period of time than the conventional methods.

    This paper focuses on the targeting of single-walled carbon nanotubes (SWNTs) for the treatment of breast cancer with minimal side effects using photothermal therapy. The human protein annexin V (AV) binds specifically to anionic phospholipids expressed externally on the surface of tumour cells and endothelial cells that line the tumour vasculature. A 2 h incubation of the SWNT-AV conjugate with proliferating endothelial cells followed by washing and near-infrared (NIR) irradiation at a wavelength of 980 nm was enough to induce significant cell death; there was no significant cell death with irradiation or the conjugate alone. Administration of the same conjugate i.v. in BALB/c female mice with implanted 4T1 murine mammary at a dose of 0.8 mg SWNT kg −1 and followed one day later by NIR irradiation of the tumour at a wavelength of 980 nm led to complete disappearance of implanted 4T1 mouse mammary tumours for the majority of the animals by 11 days since the irradiation. The combination of the photothermal therapy with the immunoadjuvant cyclophosphamide resulted in increased survival. The in vivo results suggest the SWNT-AV/NIR treatment is a promising approach to treat breast cancer. (paper)

    Full Text Available Although several surgical procedures exist for treating cubital tunnel syndrome, the best surgical option remains controversial. To evaluate the efficacy of anterior subcutaneous transposition of the ulnar nerve in patients with moderate to severe cubital tunnel syndrome and to analyze prognostic factors, we retrospectively reviewed 62 patients (65 elbows diagnosed with cubital tunnel syndrome who underwent anterior subcutaneous transposition. Preoperatively, the initial severity of the disease was evaluated using the McGowan scale as modified by Goldberg: 18 patients (28% had grade IIA neuropathy, 20 (31% had grade IIB, and 27 (42% had grade III. Postoperatively, according to the Wilson & Krout criteria, treatment outcomes were excellent in 38 patients (58%, good in 16 (25%, fair in 7 (11%, and poor in 4 (6%, with an excellent and good rate of 83%. A negative correlation was found between the preoperative McGowan grade and the postoperative Wilson & Krout score. The patients having fair and poor treatment outcomes had more advanced age, lower nerve conduction velocity, and lower action potential amplitude compared with those having excellent and good treatment outcomes. These results suggest that anterior subcutaneous transposition of the ulnar nerve is effective and safe for the treatment of moderate to severe cubital tunnel syndrome, and initial severity, advancing age, and electrophysiological parameters can affect treatment outcome.

    Full Text Available Abstract Background Increasing evidence supports somato-visceral effects of manual therapies. We have previously demonstrated that a single spinal manipulative treatment (SMT accompanied by audible release has an inhibitory effect on the production of proinflammatory cytokines in asymptomatic subjects. The purpose of this study is to report on SMT-related changes in the production of the immunoregulatory cytokine interleukin 2 (IL-2 and to investigate whether such changes might differ with respect to the treatment approach related to the presence or absence of an audible release (joint cavitation. Methods Of 76 asymptomatic subjects, 29 received SMT with cavitation (SMT-C, 23 were treated with SMT without cavitation (SMT-NC and 24 comprised the venipuncture control (VC group. The SMT-C and SMT-NC subjects received a single, similar force high velocity low amplitude manipulation, in the upper thoracic spine. However, in SMT-NC subjects, positioning and line of drive were not conducive to cavitation. Blood and serum samples were obtained before and then at 20 and 120 min post-intervention. The production of IL-2 in peripheral blood mononuclear cell cultures was induced by activation for 48 hr with Staphylococcal protein A (SPA and, in parallel preparations, with the combination of phorbol ester (TPA and calcium ionophore. The levels of IL-2 in culture supernatants and serum were assessed by specific immunoassays. Results Compared with VC and their respective baselines, SPA-induced secretion of IL-2 increased significantly in cultures established from both SMT-C and SMT-NC subjects at 20 min post-intervention. At 2 hr post-treatment, significant elevation of IL-2 synthesis was still apparent in preparations from SMT-treated groups though it became somewhat attenuated in SMT-NC subjects. Conversely, IL-2 synthesis induced by TPA and calcium ionophore was unaltered by either type of SMT and was comparable to that in VC group at all time points. No

    Although the optimal treatment mode for medulloblastoma is frequently discussed, results based on large series of cases, especially those treated in Asia, have rarely been reported. Our purpose was to evaluate the efficacy of postoperative radiation therapy, and to identify prognostic factors, in a relatively large cohort of patients with limited-stage medulloblastoma treated at a single institute in China. Between January 1996 and April 2001, 69 patients with Chang stage M0/M1 medulloblastoma were referred to our hospital for radiation therapy after total or subtotal resection of the primary tumor. All patients received 30 Gy to the craniospinal axis followed by a 20-25 Gy boost to the posterior fossa (median fraction, 1.8 Gy). Sixty-four patients were followed for a median period of 38.5 months. The rates of 3-year and 5-year overall survival were 68.8% and 55.7%, respectively; corresponding disease-free survival were 57.8% and 51.4%, respectively. Patients who had received radiation treatment within 25 days after resection had a greater probability of 3-year survival (81.5% versus 59.5%; P=0.11) and 3-year disease-free survival (74.1% versus 46.0%; P=0.03) than patients who began radiation treatment later. No relationship was found between survival and age, sex or tumor size. This regimen was comparatively ineffective in preventing recurrence of postoperative medulloblastoma; however, we found that the interval between surgery and radiation is a significant prognostic factor for disease-free survival.

    2014-06-01

    Intravenous immunoglobulin therapy is of proven effect in chronic inflammatory neuropathies, including chronic inflammatory demyelinating polyneuropathy (CIDP) and multifocal motor neuropathy (MMN). In more recent years, there have been a number of anecdotal case reports and small series, followed by a few trials of variable design, of subcutaneous immunoglobulin therapy in these neuropathies. To date, limited evidence suggests that the subcutaneous route may be a more clinically effective, better-tolerated, at least cost-equivalent and a more patient-friendly option than the still more used intravenous alternative. Long-term efficacy is not as yet established in neuropathic indications by randomised controlled clinical trial evidence, and it is likely that the subcutaneous route may not be suitable in all cases with some hints to this effect appearing from the limited data available to date. Further studies are ongoing, including those of dose comparison, and more are likely to be planned in future. The literature on the use of subcutaneous immunoglobulin therapy in chronic inflammatory neuropathy is reviewed here. The current use in clinical practice, day-to-day benefits, including quality of life measures and health economics as published thus far, are evaluated. The limitations of this form of treatment in CIDP and MMN are also analysed in the light of current literature and taking into account the remaining unknowns. Future prospects and research with this mode of immunoglobulin therapy administration are discussed.

    School-based deworming is widely implemented in various countries to reduce the burden of soil-transmitted helminths (STHs), however, the frequency of drug administration varies in different settings. In this study, we compared the impact of a single annual treatment and 4-monthly treatment over a follow-up among Kenyan school children, and investigated the factors associated with residual infection. We performed a secondary analysis of data from a randomized trial investigating whether deworming for STHs alters risk of acquiring malaria. Children received either a single treatment or 4-monthly albendazole treatments were followed longitudinally from February 2014 to October 2014. The relative impact of treatment and factors associated with residual infections were investigated using mixed-effects regression models. Predisposition to infection was assessed based on Spearman's rank and Kendall's Tau correlation coefficients. In the 4-monthly treatment group, the proportion of children infected with hookworm decreased from 59.9 to 5.7%, while Ascaris lumbricoides infections dropped from 55.7 to 6.2%. In the single treatment group, hookworm infections decreased over the same time period from 58.7 to 18.3% (12.6% absolute difference in reduction, 95% CI: 8.9-16.3%), and A. lumbricoides from 56.7 to 23.3% (17.1% absolute difference in reduction, 95% CI: 13.1-21.1%). There was strong evidence for predisposition to both STH types. Residual hookworm infection among children on 4-monthly treatment were associated with male sex and baseline nutritional status, whereas A. lumbricoides infection was associated with individual and school-level infection at baseline, latrine cleanliness at schools. This study found that 4-monthly treatment w more effective than single annual treatment. Repeated treatments led to dramatic reductions in the intensities of STHs, but did not completely clear infections among school children in Kenya, a presumed reflection of reinfection in a setting

    Highlights: • We report the long-term results (2–4 years) with Flow Diverter Devices (FDD) from a single-center. • We recommend the use of FDD for large-neck aneurysms of the ICA syphon. • We think that more sophisticate FDD will reduce the incidence of technical adverse events. - Abstract: Objectives: Flow-Diverter Devices (FDD) are a new generation stents designed for the treatment of the intracranial aneurysms. This article reports the long-term results (2–4 years) of this treatment from a single-center. Methods: From November 2008 to January 2012, 35 patients (29 females and 6 males; mean age 53.9 y) with 39 intracranial aneurysms were treated by FDD. Five patients (14.3%) had ruptured aneurysms and 30 (85.7%) had no previous hemorrhage. The procedures were performed in 5 patients (14.3%) with SILK and in 30 (85.7%) with PED. In 3 patients FDDs were used as a second treatment after failure of previous coiling (2 cases) or stenting (one case). The 39 aneurysms were in supraclinoid ICA in 26 (66.7%), cavernous ICA in 2 (5.1%), PCoA in 4 (10.2%), MCA in 5 (12.9%), SCA in 1 (2.6%) and PICA in 1 (2.6%). The aneurysms were small (<10 mm) in 32 cases (82%), large (11–25 mm) in 6 (15.3%) and giant in 1 (2.6%). The occlusion rate according to the aneurysm location, size and neck and the complications were evaluated. Results: Peri-procedural complications included transient dysarthria (2 patients), vasospasm with acute intra-stent aggregation (one), microwire rupture (one) and failure of the stent opening (one). The follow-up was made between 24 and 62 months (mean 41 months); clinical examination and CTA were performed at 1, 3, 6 and 12 months after the procedure. The complete occlusion was confirmed by CTA and DSA. MRI with angiographic-studies was taken every year. Complete occlusion was obtained in 35 aneurysms (92.1%) and subtotal in 3 (7.9%). Complete occlusion occurred at 3 months in 24 cases (68.6%), within 3 and 6 months in 9 (25.7%). The rate and

    This paper aims to describe clinical and laboratory features and disease outcome in a single-centre cohort of patients with PFAPA syndrome (Periodic Fever, Aphtous stomatitis, Pharyngitis, and Adenitis) and to test performance of diagnostic and therapeutic algorithms. Patients fulfilling criteria were selected from the fever clinic population. Prospective follow-up together with recruitment of newly diagnosed patients followed pre-defined guidelines. Diagnostic and therapeutic algorithms and definitions of outcome and therapy response were formulated. Paired blood samples during febrile and afebrile periods were compared. Out of 176 patients referred for suspected periodic fever 125 children fulfilled criteria. Their age at onset was 23 months, median episode duration 3.5 days at 4-week intervals. Fever was associated with pharyngitis (91%), cervical adenitis (78%) and aphtae (41%). Among therapeutic options, episodic prednisone proved to be the most common first-line treatment. Administered to 77 patients, it reduced symptoms in 94%. Tonsillectomy led to the full symptom resolution in all 18 patients. Forty-six patients reached disease remission. Distribution of typical symptoms, response to therapies and disease outcome in a large patient cohort were documented. We offer diagnostic and therapeutic algorithms that have proven effective during this prospective trial. Our findings support the general belief of benign nature of this aetiologically unclear condition, despite proportion of patients having persistent disease for years. Maintenance of normal findings in afebrile intervals, striking response to a single dose of prednisone and normal growth and development together with spontaneous tendency towards prolongation of afebrile intervals are important confirmatory features of PFAPA syndrome.

    A single dose of florfenicol (Nuflor(®)) was administered to eight healthy adult alpacas at 20 mg/kg intramuscular (i.m.) and 40 mg/kg subcutaneous (s.c.) using a randomized, cross-over design, and 28-day washout period. Subsequently, 40 mg/kg florfenicol was injected s.c. every other day for 10 doses to evaluate long-term effects. Maximum plasma florfenicol concentrations (C(max), measured via high-performance liquid chromatography) were achieved rapidly, leading to a higher C(max) of 4.31±3.03 μg/mL following administration of 20 mg/kg i.m. than 40 mg/kg s.c. (C(max): 1.95±0.94 μg/mL). Multiple s.c. dosing at 48 h intervals achieved a C(max) of 4.48±1.28 μg/mL at steady state. The area under the curve and terminal elimination half-lives were 51.83±11.72 μg/mL·h and 17.59±11.69 h after single 2 mg/kg i.m. dose, as well as 99.78±23.58 μg/mL·h and 99.67±59.89 h following 40 mg/kg injection of florfenicol s.c., respectively. Florfenicol decreased the following hematological parameters after repeated administration between weeks 0 and 3: total protein (6.38 vs. 5.61 g/dL, Pflorfenicol should thus be used in alpacas and limited to treatment of highly susceptible pathogens. © 2011 Blackwell Publishing Ltd.

In this study, single- and 5-day multiple-dose pharmacokinetics were characterized in nine Caucasian volunteers after subcutaneous administration of 900 microg/m2 thymosin alpha1. Using a randomized, 3-way crossover design three available drug formulations were compared: Zadaxin (SciClone), Timosina (Sclavo), and Thymosin alpha1 (Tal-HLR; Hoffmann La Roche). AUC, Cmax, t(max), t(1/2), Cl/f, and the volume of distribution, V(Z)/f, were derived by model-independent methods. Endogenous serum concentrations were below the limit of quantification (0.10 microg/l) of the enzyme-linked immunosorbent assay method in most subjects. Thymosin alpha1 was well absorbed with a mean t(max) between 1-2 hours from all galenic formulations. Cmax concentrations of 30 to 80 microg/l and AUC(0-infinity) from 95 to 267 microg x h/l did not differ between single- and multiple-dose administration of all drugs. This apparent lack of accumulation was supported by the short elimination half-life of less than 3 hours. As indicated by a V(Z)/f in the range of 30-40 l, thymosin alpha1 appears to distribute within the extracellular volume. AUC and Cmax were similar for Zadaxin and T alpha1-HLR, but higher after administration of Timosina. Thymosin alpha1 kinetics from this study are comparable to those previously obtained in Japanese volunteers or cancer patients, but may be influenced by the drug formulation used.

    Allergen immunotherapy is effective in patients with allergic rhinitis (AR) and, unlike antiallergic drugs, has been shown to modify the underlying cause of the disease, with proved long-term benefits. Subcutaneous immunotherapy (SCIT) has been the gold standard, whereas sublingual immunotherapy (SLIT) has emerged as an effective and safe alternative. Previous Cochrane systematic reviews and meta-analyses have confirmed that both SLIT and SCIT are effective in patients with seasonal AR, whereas evidence for their efficacy in patients with perennial disease has been less convincing. Recent large, adequately powered trials have demonstrated reductions in both symptoms and use of rescue medication in patients with seasonal and those with perennial AR. Here we appraise evidence for SCIT versus SLIT based on indirect evidence from Cochrane reviews and recent well-powered double-blind, randomized controlled trials versus placebo and the limited direct evidence available from randomized blind head-to-head comparisons. At present, based on an overall balance of efficacy and side effects, the patient is in equipoise. Pending definitive comparative trials, choice might be determined largely by the local availability of SCIT and SLIT products of proved value and personal (patient) preference.

    Intensity-modulated particle therapy (IMPT) for tumors showing interfraction motion is a topic of current research. The purpose of this work is to compare three treatment strategies for IMPT to determine potential advantages and disadvantages of ion prostate cancer therapy. Simulations for three treatment strategies, conventional one-plan radiotherapy (ConvRT), image-guided radiotherapy (IGRT), and online adaptive radiotherapy (ART) were performed employing a dataset of 10 prostate cancer patients with six CT scans taken at one week intervals. The simulation results, using a geometric margin concept (7-2 mm) as well as patient-specific internal target volume definitions for IMPT were analyzed by target coverage and exposure of critical structures on single fraction dose distributions. All strategies led to clinically acceptable target coverage in patients exhibiting small prostate motion (mean displacement < 4 mm), but IGRT and especially ART led to significant sparing of the rectum. In 20 % of the patients, prostate motion exceeded 4 mm causing insufficient target coverage for ConvRT (V95{sub mean} = 0.86, range 0.63-0.99) and IGRT (V95{sub mean} = 0.91, range 0.68-1.00), while ART maintained acceptable target coverage. IMPT of prostate cancer demands consideration of rectal sparing and adaptive treatment replanning for patients exhibiting large prostate motion. (orig.)

    Impaired fear memory extinction is widely considered a key mechanism of post-traumatic stress disorder (PTSD). Recent studies have suggested that neuroinflammation after a single prolonged stress (SPS) exposure may play a critical role in the impaired fear memory extinction. Studies have shown that high mobility group box chromosomal protein 1 (HMGB-1) is critically involved in neuroinflammation. However, the role of HMGB-1 underlying the development of impairment of fear memory extinction is still not known. Thus, we examined the levels of HMGB-1 in the basolateral amygdala (BLA) following SPS using Western blot and evaluated the levels of microglia and astrocytes activation in the BLA after SPS using immunohistochemical staining. We then examined the effects of pre-SPS intra-BLA administration of glycyrrhizin, an HMGB1 inhibitor, or LPS-RS, a competitive TLR4 antagonist, on subsequent post-SPS fear extinction. We found that SPS treatment prolonged the extinction of contextual fear memory after the SPS. The impairment of SPS-induced extinction of contextual fear memory was associated with increased HMGB1 and Toll-like receptor 4 (TLR4) levels in the BLA. Additionally, the impairment of SPS-induced extinction of contextual fear memory was associated with increased activation of microglia and astrocyte in the BLA. Intra-BLA administrations of glycyrrhizin (HMGB-1 inhibitor) or LPS-RS (TLR4 antagonist) can prevent the development of SPS-induced fear extinction impairment. Taken together, these results suggested that SPS treatment may not only produce short term effects on the HMGB1/TLR4-mediated pro-inflammation, but alter the response of microglia and astrocytes to the exposure to fear associated contextual stimuli. © 2018 The Author(s).

    Twenty-two patients with mild putaminal hemorrhage (neurological grades 1 and 2) were divided into three groups. Four (conservative group) received conservative treatment. Thirteen (aspiration group) underwent CT-guided stereotactic aspiration. Four (craniotomy group) underwent microsurgical evacuation of the hematoma. Surgical treatments were performed within 6 days after the onset. We measured the cerebral blood flow (CBF) using single-photon-emission CT and the [sup 133]Xe-inhalation method. The CBF was measured at the acute stage (Days 1-7), at the subacute stage (Days 8-14), and at the chronic stage (one month after the onset). In putaminal hemorrhage with both neurological grades 1 and 2 and with 2 only, the mean hemispheric CBF (mCBF) of the hematoma and the nonhematoma side among the three groups had no significance at any stage. In each group, no improvement in the reduction of mCBF was observed. In putaminal hemorrhage with neurological grade 1 only, however, the mCBF of the hematoma side at the chronic stage was 47.8[+-]6.7 ml/100 g/min in the conservative group and 59.1[+-]7.6 ml/100 g/min in the aspiration group. This difference was statistically significant. In the aspiration group, the mCBF values of both sides and the regional CBF (rCBF)-A[center dot]L[center dot]P at the chronic stage increased significantly compared with those at the acute and subacute stage. On the other hand, in the conservative group, no improvement in the reduction of CBF at the chronic stage was observed. From the serial measurement of CBF, it was observed that, compared with conservative therapy, CT-guited stereotactic aspiration for putaminal hemorrhage with neurological grade 1 is more effective.

    Most cases of idiopathic nephrotic syndrome in childhood are responsive to corticosteroids. However, there is a small group of children that demonstrate steroid resistance (steroid-resistant nephrotic syndrome; SRNS), steroid dependence, or that frequently relapse (frequent-relapse steroid-sensitive nephrotic syndrome; FR-SSNS) which are more clinically difficult to treat. Therefore, second-line immunosuppressants, such as alkylating agents, calcineurin inhibitors, antimetabolites and, more recently, rituximab, have been used with varying success. The objective was to evaluate the response rates of various second-line therapies in the treatment of childhood nephrotic syndrome. A retrospective chart review of pediatric subjects with idiopathic nephrotic syndrome was conducted at a single tertiary care center (2007-2012). Drug responses were classified as complete response, partial response, and no response. Of the 188 charts reviewed, 121 children were classified as SSNS and 67 children as SRNS; 58% were classified as FR-SSNS. Sixty-five subjects were diagnosed with focal segmental glomerulosclerosis via biopsy. Follow-up ranged from 6 months to 21 years. The combined rate of complete and partial response for mycophenolate mofetil (MMF) was 65% (33/51) in SSNS and 67% (6/9) in SRNS. For tacrolimus, the response rate was 96% (22/23) for SSNS and 77% (17/22) for SRNS. Eighty-three percent (5/6) of SSNS subjects treated with rituximab went into complete remission; 60% relapsed after B-cell repletion. Eight refractory subjects were treated with combined MMF/tacrolimus/corticosteroid therapy with a 75% response rate. Our experience demonstrates that older medications can be replaced with newer ones such as MMF, tacrolimus, and rituximab with good outcomes and better side effect profiles. The treatment of refractory cases with combination therapy is promising.

    Clinicians are regularly confronted with difficult choices. Should a tooth that has not healed through nonsurgical root canal treatment be treated through endodontic microsurgery or be replaced using a single implant? Acquiring complete, unbiased information to help clinicians and their patients make these choices requires a systematic review of the literature on treatment outcomes. The purpose of this systematic review was to compare the outcomes of tooth retention through endodontic microsurgery to tooth replacement using an implant supported single crown. Searches performed in PubMed, Cochrane Library, Web of Science, and EMBASE databases were enriched by citation mining. Inclusion criteria were defined. Sentinel articles were identified and included in the final selection of studies. Weighted survival and success rates for single implants and endodontic microsurgery were calculated. The quality of the articles reporting on single implants and endodontic microsurgery was moderate. Data for single implants were much more plentiful than for endodontic microsurgery, but the endodontic microsurgery studies had a slightly higher quality rating. Single implants and endodontic microsurgery were not directly compared in the literature. Outcomes criteria were often unclear. At 4-6 years, single implants had higher survival rates than teeth treated with endodontic microsurgery. Qualitatively different success criteria precluded valid comparison of success rates. Survival rates for single implants and endodontic microsurgery were both high (higher for single implants). Appraisal was limited by a lack of direct treatment comparisons. Long-term studies with a broad range of carefully defined outcomes criteria are needed. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    An effort is made to introduce thermodynamic and statistical thermodynamic methods into the treatment of nonphysical (e.g., social, economic, etc.) systems. Emphasis is placed on the use of the entire thermodynamic framework, not merely entropy. Entropy arises naturally, related in a simple manner to other measurables, but does not occupy a primary position in the theory. However, the maximum entropy formalism is a convenient procedure for deriving the thermodynamic analog framework in which undetermined multipliers are thermodynamic-like variables which summarize the collective behavior of the system. The authors discuss the analysis of Levine and his coworkers showing that the maximum entropy formalism is the unique algorithm for achieving consistent inference of probabilities. The thermodynamic-like formalism for treating a single lane of vehicular traffic is developed and applied to traffic in which the interaction between cars is chosen to be a particular form of the ''follow-the-leader'' type. The equation of state of the traffic, the distributions of velocity and headway, and the various thermodynamic-like parameters, e.g., temperature (collective sensitivity), pressure, etc. are determined for the example of the Holland Tunnel. Nearest-neighbor and pair correlation functions for the vehicles are also determined. Interesting and suggestive results are obtained

    Purpose: To assess the survival rate of female lung cancer treated at the Institute of Oncology of the Vilnius University, Lithuania during the period between 1996-2005. Materials and Methods: During the period between 1996-2005, 471 women diagnosed with lung cancer were treated at the Department of Thoracic Surgery and Oncology of the Institute of Oncology, Vilnius University. Data on morphology, stage and treatment was collected from the medical records. All lung cancer cases by histology were classified in two groups: non-small cell lung cancer (includes squamous cell carcinoma, large cell carcinoma, adenocarcinoma and other less common types) and small cell lung cancer. The vital status of the study group was assessed as of December 31, 2007, by passive follow-up, using data from the population registry. It was found that 411 (87.3%) of the patients had died. Survival was estimated according to the Kaplan-Meier method. Results: The median survival of female lung cancer diagnosed during 1996-2005 in Lithuania show to be 8.7 months (8.4 (95% CI 7.2-10.8) months with non-small cell lung cancer and 9.3 (95% CI 6.3-13.0) months with small-cell lung cancer). Survival was more than 20 months in resectable non-small cell lung cancer (stages I, II, IIIA). Non-small cell lung cancer survival in advanced stages was less than 7 months. Small-cell lung cancer patients median survival at limited and extended stages of the disease were 9.5 (95% CI 2.9-18.4) compared to 9.2 (95% CI 6.2-13.7) months. Non-small cell lung cancer patients most frequently were treated by surgery (27.0%), surgery and chemotherapy or radiotherapy (19.6%). Small cell lung cancer patient treatment included chemo and radiotherapy (27.0%), chemotherapy (19.0%), radiotherapy (17.5%), surgery (27.9%). Conclusions: The single center study of female lung cancer diagnosed during 1996-2005 in Lithuania show a significantly better chance of survival in resectable non-small cell lung cancer.

    The development of ultrasonography allowed for skin imaging used in dermatology and esthetic medicine. By means of classic and high-frequency ultrasonographies, changes within the dermis and subcutaneous tissue can be presented. The aim of this study was to show the possibilities of applying classic and high-frequency ultrasonographies in esthetic dermatology based on monitoring various types of anti-cellulite therapies. Sixty-one women with cellulite were assigned to two smaller groups. One group was using anti-cellulite cream and the second group was a placebo group. The ultrasound examination was carried out before the initiation and after the completion of the treatment and evaluated epidermal echoes, the thickness of the subcutaneous tissue and the dermis, dermis echogenicity, the length and surface area of the subcutaneous tissue fascicles growing into the dermis, and the presence or absence of edemas. After the completion of the treatment, a statistically significant difference was observed. The most useful parameters were as follows: the thickness of the subcutaneous tissue, echogenicity, the surface area and length of the subcutaneous tissue, as well as the presence of edemas. The discussed changes were not observed in the placebo group. Classic and high-frequency ultrasonographies are useful methods for monitoring anti-cellulite therapies. © 2011 John Wiley & Sons A/S.

    Can a two-dose methotrexate treatment protocol improve the treatment success rate compared with a single-dose protocol in women with an ectopic pregnancy? The two-dose protocol was not superior to the single-dose protocol for the treatment of ectopic pregnancy. Although the two-dose methotrexate protocol for ectopic pregnancy was recently introduced to combine the efficacy and convenience of the fixed multi-dose and single-dose protocols, studies comparing the success rates, treatment satisfaction and acceptability of the single-dose and two-dose treatment protocols for ectopic pregnancy are currently lacking. A randomized trial was conducted on 92 participants with tubal ectopic pregnancy, between May 2013 and April 2015. Patients who were diagnosed with tubal ectopic pregnancy and who elected to undergo systemic methotrexate treatment were randomly assigned to follow either the single-dose (n = 46) or two-dose protocol (n = 46). The primary outcome measure was treatment success without surgical intervention. The secondary outcome measures were the incidence of methotrexate-associated side effects, β-human chorionic gonadotrophin (β-hCG) resolution time, cost of care received and treatment satisfaction. There were no differences in baseline characteristics between the groups. The success rates between the single-dose and two-dose groups did not show a significant difference [82.6 versus 87.0%; relative risk (RR) 0.95; 95% confidence interval (CI) 0.80-1.13]. However, the success rate in a subgroup of participants with a pretreatment β-hCG level of >5000 mIU/ml appeared to be higher in the two-dose group than in the single-dose group (80.0 versus 58.8%), although the difference was not statistically significant. No significant differences in methotrexate-associated side effects, cost or treatment satisfaction were observed between the groups. The two-dose group required a lower number of days for the β-hCG level to decrease to ectopic pregnancy. None. www

    Intense pulsed light (IPL) and fractional photothermolysis (FP) are effective nonablative treatments for photoaging. To investigate the safety and efficacy of administering these two treatments in the same session with the aim of maximizing results while maintaining safety and minimizing downtime. We sought to compare the efficacy of the combination treatment with that of individual treatments of IPL and FP by conducting a split-face study. Twenty-nine subjects received a full-face standard-strength treatment with IPL immediately followed by treatment with 1550-nm FP. A further 14 patients underwent a split-face study comparing combined IPL and FP on one side of the face with these two treatments performed in isolation, 4 weeks apart, on the other side. The combination treatment achieved results statistically superior to treatment with IPL alone, FP alone, and treatment with IPL and FP performed 4 weeks apart. Downtime and adverse events were similar to those expected with individual treatments of IPL or FP alone. Intense pulsed light and PF appear to be synergistic when performed together in a single session, and the combination treatment is associated with a good safety profile and minimal downtime. © 2012 by the American Society for Dermatologic Surgery, Inc.

In all groups subcutaneous blood flow decreased at the onset of hypoglycaemic symptoms...... compared with pre-hypoglycaemic flow. Two hours after onset of hypoglycaemic symptoms, subcutaneous blood flow was still significantly decreased compared with pre-hypoglycaemic flow. In normal subjects local nerve blockade had no effect on blood flow changes during hypoglycaemia, whereas local alpha......-receptor blockade abolished the vasoconstrictor response. We suggest that circulating catecholamines stimulating vascular alpha-receptors are probably responsible for flow reduction in the subcutaneous tissue during hypoglycaemia....

    Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed. Demographics and procedural to 30-day outcomes were assessed. All patients had good blood flow to the hand after intervention and none experienced complications during or immediately post-procedure. At 30-days the freedom from revascularization and amputation was 100%, and all the wounds were healed. The following important principles were followed during the use of OAS for CHI: (1) ACT was therapeutic (~250s); (2) Gentle wire manipulation; (3) Utilization of a small OAS crown (1.25mm); (4) Aggressive vasodilator use-given through the exchange catheter; (5) Angioplasty balloon was matched to the size of the vessel and long and low pressure inflations were completed. Critical hand ischemia can be treated with endovascular techniques. Obtaining good outflow to the fingers is critical for wound healing and preventing amputation. Orbital atherectomy is a useful tool in preparing vessels for balloon angioplasty; particularly in cases where calcification is present. Copyright © 2016 The Authors. Published by Elsevier Inc.

    The morbidity of diabetes mellitus is increasing, and subcutaneous injection of exogenous insulin is well established as an effective therapeutic strategy for reducing complications associated with the disease. However, the pain that accompanies repeated injections is an important drawback, and can detrimentally affect the adherence to therapy. Recently, there have been great improvements in injection devices and techniques, including the development of microneedle systems and quantitative injection technologies, which have increased the accuracy of injection, decreased leakage of insulin to the skin surface, and reduced pain. Areas covered: This review highlights some limitations of current techniques for the injection of insulin and its analogs, and describes new methodologies and strategies that have been developed in an attempt to overcome these limitations. Furthermore, novel technologies currently under development that are potential future prospects for insulin delivery are discussed. Expert opinion: New technologies have provided easier and well-tolerated treatment regimens for diabetes patients. However, to further improve patients' satisfaction, self-regulated insulin delivery, automatic adjustment of needle length, memory function to the injection device, use of novel materials could be introduced into insulin injection. Intelligent control of insulin delivery and soluble microneedle arrays may be important areas of future research.

    Allergen immunotherapy is the sole treatment for IgE-mediated allergic diseases directed at the underlying mechanism. The two widely accepted administration routes are sublingual (SLIT) and subcutaneous (SCIT). We reviewed how patients should best be selected for immunotherapy and how the optimal administration route can be defined. Before deciding SCIT or SLIT, appropriate selection of patients for allergen immunotherapy (AIT) is mandatory. To be eligible for AIT, subjects must have a clear medical history of allergic disease, with exacerbation of symptoms on exposure to one or more allergens and a corresponding positive skin or in vitro test. Then the route of administration should be based on: published evidence of clinical and immunologic efficacy (which varies per allergic disease and per allergen); mono- or multi-allergen immunotherapy, for SLIT multi-allergen immunotherapy was not effective; safety: adverse events with SLIT are more frequent, but less severe; and, costs and patient preferences, closely related to adherence issues. All these are discussed in the article.

    Body mass index (BMI) has been shown to influence the outcome of various surgical procedures. The purpose of this study is to assess the relationship between BMI, gender, and the distribution of subcutaneous and perirenal fat. A retrospective review was performed for 123 patients who underwent radical or partial nephrectomy. Preoperative CT scans were reviewed by two independent observers. Subcutaneous fat was measured at three locations and perirenal fat was measured at six locations. Statistical analysis was performed using the Student's t test and the Pearson's correlation coefficient. Mean anterior subcutaneous fat was significantly greater in females than in males (2.54 vs. 1.78 cm, p fat (2.78 vs. 2.21 cm, p = 0.03). With regard to perirenal fat, men were greater than women for all perirenal locations around the left kidney. For the right kidney, men were greater than women for four out of six perirenal positions. In both men and women, BMI was strongly correlated with subcutaneous fat. However, BMI was weakly correlated with perirenal fat. Women exceed men in subcutaneous fat, while men exceed women in perirenal fat. Obese patients are very likely to have large amounts of subcutaneous fat, but will not necessarily have proportionally increased fat around their kidneys when compared to the patients with lower BMI. These differences may have important implications for surgical approaches to the kidney.

    The use of single-dose intramuscular administration of methotrexate in the treatment of ectopic pregnancies (EP) is a well-established practice. This study evaluates its use at a novel dose of 40 mg/m(2) body surface area (BSA). To evaluate the efficacy and safety of single-dose methotrexate treatment 40 mg/m(2) for tubal EP and persistent pregnancies of unknown location (PUL) and determine whether serum progesterone is a predictor of treatment success. Retrospective cohort study of patients receiving intramuscular methotrexate 40 mg/m(2) for the treatment of EP or PUL at Royal Prince Alfred Hospital over five years. One hundred and eighteen women received single-dose methotrexate with an overall success of 84%. Surgical intervention was needed in 16.6%. Pretreatment beta-hCG level and ectopic diagnosis were independent variables predictive of the need for surgery (P = 0.003 and 0.02, respectively). Serum progesterone level was not predictive of the need for a second dose or surgery. The sensitivity and specificity at pretreatment beta-hCG of 1202 IU/L were 84% and 74%, respectively. Commonly reported side effects included nausea, abdominal pain and heavy vaginal bleeding. Significant treatment-related adverse effects were rare. Single-dose IM methotrexate at a novel dose of 40 mg/m(2) is a safe and effective treatment for selected EP and persistent PUL. The risk of surgery was positively correlated to serum beta-hCG level and the diagnosis of EP. Progesterone was not a risk factor for surgery. Further studies are required to confirm the efficacy of this dose regimen and explore the safety of expectant management as an alternative to methotrexate treatment. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Generalized subcutaneous edema is a very rare manifestation of inflammatory myopathies. A 61-year-old woman presented with classic signs and symptoms of dermatomyositis. She was also noted to have generalized edema that was so florid that an alternative diagnosis was considered. Her disease was resistant to corticosteroids, azathioprine, and mycophenolate mofetil. Intravenous administration of immunoglobulins was started because of marked worsening of her disease-muscle weakness, generalized anasarca, and involvement of her bulbar muscles. This led to dramatic resolution of her subcutaneous edema and significant improvement of her skin and muscle disease. As the initial screen for malignancy was negative, a positron emission tomography-computed tomography scan was requested, which interestingly showed a metabolically active cervical tumor. Anasarca is an unusual manifestation of dermatomyositis. In treatment-refractory cases, it seems reasonable to consider positron emission tomography scan in excluding underlying malignant disease.

    Comparing biologic persistence and healthcare costs between rheumatoid arthritis (RA) patients initiating first- or second-line subcutaneous abatacept, adalimumab, or etanercept. Retrospective, observational cohort study, which included adults with RA who initiated either of the three treatments between 29 July 2011 and 1 July 2015. Total healthcare costs were measured during baseline and follow-up. Biologic persistence was compared using multivariable Cox proportional hazards regression. Subcutaneous abatacept-treated patients had numerically lowest adjusted hazards of nonpersistence and increase from baseline in total healthcare costs. Sensitivity analyses measuring outcomes over an alternative follow-up definition produced consistent results. Abatacept-treated RA patients appeared to have the poorest health status yet often had the lowest increase from baseline in healthcare costs and longest duration of biologic persistence.

    Full Text Available A Target Animal Safety protocol was used to examine adverse events in male and female Fischer F344/NTac rats treated with increasing doses of a subcutaneous implant of a lipid suspension of buprenorphine. A single injection of 0.65 mg/kg afforded clinically significant blood levels of drug for 3 days. Chemistry, hematology, coagulation, and urinalysis values with 2- to 10-fold excess doses of the drug-lipid suspension were within normal limits. Histopathology findings were unremarkable. The skin and underlying tissue surrounding the drug injection were unremarkable. Approximately 25% of a cohort of rats given the excess doses of 1.3, 3.9, and 6.5 mg/kg displayed nausea-related behavior consisting of intermittent and limited excess grooming and self-gnawing. These results confirm the safety of cholesterol-triglyceride carrier systems for subcutaneous drug delivery of buprenorphine in laboratory animals and further demonstrate the utility of lipid-based carriers as scaffolds for subcutaneous, long-acting drug therapy.

    2017-02-01

    Background: The skin tightening effects induced by non-insulated microneedle radiofrequency have proved long-lasting. Our previous three-dimensional volumetric assessment showed significant facial tightening for up to six months. However, nasal and peri-oral tightening effects lasted longer. The objective of this study was to investigate the distribution of the long-term volumetric reduction in facial area induced by a single fractional non-insulated microneedle radiofrequency treatment. Methods: Fifteen Asian patients underwent full facial skin tightening using a sharply tapered non-insulated microneedle radiofrequency applicator with a novel fractionated pulse mode. Three-dimensional volumetric assessments were performed at six and 12 months post-treatment. Patients rated their satisfaction using a 5-point scale at each follow up. Results: Objective assessments with superimposed three-dimensional color images showed significant volumetric reduction in the nasal and peri-oral areas at 12 months post-treatment in all patients. Median volumetric reductions at six and 12 months post-treatment were 13.1 and 12.3ml, respectively. All of the patients were satisfied with their results 12 months post-treatment. Side effects were not observed. Conclusions: This single fractional NIMNRF treatment provided long-lasting nasal and peri-oral tightening as shown via 3D volumetric assessment. Moreover, NIMNRF produced minimal complications, downtime, and few side effects. This approach provides safe and effective treatment of skin tightening.

O tratamento medicamentoso foi instituído após incisão, drenagem e lavagem com solução antisséptica para a retirada de quaisquer materiais ainda presentes no sítio da lesão. Apenas dois animais apresentaram recidivas, atribuídas à utilização inadequada da terapêutica e à não-manutenção das regras de higiene no pós-operatório. A associação em questão provou ser eficaz, as incisões para drenagem devem ser realizadas na parte mais ventral da lesão e a resolução do processo patológico deve ocorrer entre o 10° e 15° dias.

    The utilization of methacresolsulphonic acid topically, associated with nitrofurazone, in addition to the parenteral application of enrofloxacin was described in the treatment of subcutaneous abscesses in 36 animals (22 bovines, four caprines, five equines, two swines, one ovine, one mule and one buffalo. Medical treatment was initiated after incision; drainage and lavage of the abscess with an antiseptic solution were made in order to remove any foreign material which might still be in the lesion. Only two animals showed relapses, attributed both to the inadequate utilization of the therapeutic procedures and to the non-observation of post-operatory hygienic measures. The association of these drugs proved to be effective and the drainage should be attempted in the more ventral area of the

    Stathmin-1 (STMN1) is a microtubule-destabilizing protein which is overexpressed in cancer. Its overexpression is associated with poor prognosis and also serves as a predictive marker to taxane therapy. We have developed a proprietary bi-functional shRNA (bi-shRNA) platform to execute RNA interference (RNAi)-mediated gene silencing and a liposome-carrier complex to systemically deliver the pbi-shRNA plasmids. In vitro and in vivo testing demonstrated efficacy and specificity of pbi-shRNA plasmid in targeting STMN1 (Phadke, A. P., Jay, C. M., Wang, Z., Chen, S., Liu, S., Haddock, C., Kumar, P., Pappen, B. O., Rao, D. D., Templeton, N. S., et al. (2011). In vivo safety and antitumor efficacy of bifunctional small hairpin RNAs specific for the human Stathmin 1 oncoprotein. DNA Cell Biol. 30, 715-726.). Biodistribution and toxicology studies in bio-relevant Sprague Dawley rats with pbi-shRNA STMN1 lipoplex revealed that the plasmid DNA was delivered to a broad distribution of organs after a single subcutaneous injection. Specifically, plasmid was detected within the first week using QPCR (threshold 50 copies plasmid/1 µg genomic DNA) at the injection site, lung, spleen, blood, skin, ovary (limited), lymph nodes, and liver. It was not detected in the heart, testis or bone marrow. No plasmid was detected from any organ 30 days after injection. Treatment was well tolerated. Minimal inflammation/erythema was observed at the injection site. Circulating cytokine response was also examined by ELISA. The IL-6 levels were induced within 6 h then declined to the vehicle control level 72 h after the injection. TNFα induction was transiently observed 4 days after the DNA lipoplex treatment. In summary, the pbi-shRNA STMN1 lipoplex was well tolerated and displayed broad distribution after a single subcutaneous injection. The pre-clinical data has been filed to FDA and the pbi-shRNA STMN1 lipoplex is being investigated in a phase I clinical study. © The Author 2016. Published

    Full Text Available Background: Nowadays, The first step in treatment of ectopic pregnancy (EP is medical treatment. Medical treatment with methotrexate (MTX for EP is safe and effective method without the risks associated with the surgical procedure. But there are controversies between studies for which patients will respond better to medical treatment. Objective: The aim of the present study was to investigate the predictive factors of success or failure of treatment of EP with single dose MTX. Materials and Methods: In this retrospective study, records of 370 patients who were treated for tubal EP with single dose of MTX were reviewed during four years. Patients were divided into two groups; the first group or “success group” are the patients who were successfully treated with MTX. The second group or “failure group” consist the patients who did not respond to the MTX therapy. The week of gestation, size and location of EP and β-hCG level were compared between groups. Results: Of 370 patients, 285 (77.1% were successfully treated with MTX. 85 patients (22.9% required surgery after a mean of 5.4 (range 2-15 days. Day-1 beta- human chorionic gonadotropin (β-hCG and fall in β-hCG between day 1 and day 4 were the best predictors for single dose MTX treatment success. The cutoff value of initial β-hCG with the success treatment results was found to be 1375 IU/mL there was no statistical difference between groups about week of gestation, size and location of EP. Conclusion: The results showed that patients who have β-hCG levels below 1375 and the number of cases with decreasing β-hCG level on day 4 are the good candidates for medical treatment.

    Danofloxacin is a fluoroquinolone developed for use in veterinary medicine. Its concentrations and pharmacokinetic profile in plasma, milk and tissues of lactating dairy cows were determined, and its milk withdrawal time (WT) calculated. Twenty-one dairy cows received a single subcutaneous administration of 18% mesylate danofloxacin salt (6 mg kg{sup -1}). Plasma and milk samples were obtained at different times until 48 h. Groups of three animals were sacrificed at different post-administration times and tissue samples (mammary gland, uterus, duodenum, jejunum, ileum, colon and mesenteric lymph nodes) obtained. Danofloxacin concentrations were determined by liquid chromatography with fluorescence detection. The milk WT was calculated by the Time to Safe Concentration method (Software WTM 1.4, EMEA). Danofloxacin was rapidly absorbed and its distribution from plasma to all sampled tissues and milk was extensive. Milk and tissues concentrations were several times above those found in plasma. Plasma area under the curve (AUCp) was 9.69 {mu}g h mL{sup -1} and its elimination half life (T{sub {beta}}{sup 1/2}) was 12.53 h. AUC values for the various tissues and milk greatly exceeded AUCp. T{sub {beta}}{sup 1/2} from milk and tissues ranged between 4.57 and 21.91 h and the milk withdrawal time was 73.48 h. The reported results support the potential use of danofloxacin in the treatment of mastitis and other infections in milk cows with 3 days of withdrawal.

    We modified a subcutaneous anchor attachment and achieved transmitter reten- tion times that exceeded those reported previously for other attachments used on alcids. Traditional suture and epoxy attachment methods were used on Xantus' Murrelets in 1995 and 1996, while the modified attachment was used for Xantus' Murrelets in 1996 and 1997 and Marbled Murrelets in 1997. Modifications included use of an inhalant anesthetic, placing the anchor in a more cranial position on the back, application of marine epoxy, and place- ment of a single subcutaneous non-absorbable suture at the caudal end of the radio to hold the radio in place initially. We located 22 of 56 (39%) Xantus' Murrelets radio-marked using suture and epoxy during aerial surveys in 1995 and 1996. Of birds radio-marked using the subcutaneous anchor attachment, we located 92 of 113 (81%) Xantus' Murrelets marked in 1996 and 1997 and all 28 (100%) Marbled Murrelets marked in 1997 during aerial surveys. The maximum confirmed duration for the subcutaneous anchor transmitter attachment was 51 d for Xantus' Murrelets and 78 d for Marbled Murrelets versus 41 d for the suture and epoxy attachment used on Xantus' Murrelets. Recapture rates of radio-marked Xantus' Mur- relets were similar to recapture rates of unmarked Xantus' Murrelets. Our post-release ob- servations indicated negligible short-term physical effects from the attachment procedure, while telemetry data and examination of recaptured murrelets indicated no evidence of infection or other long-term physical effects. Breeding behavior of some murrelets was not disrupted; however, further evaluation of potential effects of this attachment technique on breeding and behavior is needed.

    Passive acoustic treatments, also called liners, are the main solution to noise problems. The Single Degree Of Freedom (SDOF) acoustic treatment, composed of a thin material (perforated plate) affixed to air cavities with a rigid bottom, constitutes a solution. Predicting sound level reduction by an SDOF treatment requires reliable acoustic impedance models. An experimental/numerical method has been developed for a duct with an acoustic treatment to test acoustic impedance models of SDOF treatment with a multimodal propagation in the presence of a mean flow. This method is based on the comparison of experimental results from an aeroacoustic bench composed of a circular duct with a treated area, and numerical results from an FEM-PML axisymmetric model based on Galbrun's equation. The numerical results are confronted with experimental results to test impedance models up to M 0 =±0.25.

The aim of the current study is to describe a single centre analysis of the clinical characteristics and surgical treatment of PENs. Patients and Methods. This is a cohort analysis of 40 patients of PENs who underwent surgery at Sir Ganga Ram Hospital, New Delhi, India, from 1995 to 2013. Patient particulars, clinical features, surgical interventions, postoperative outcome, and followup were done and reviewed. The study group was divided based on grade (G1, G2, and G3 and functionality (nonfunctioning versus functioning for comparison. Results. PENs comprised 6.3% of all pancreatic neoplasms (40 of 634. Twenty-eight patients (70% had nonfunctioning tumours. Eighteen PENs (45% were carcinomas (G3, all of which were nonfunctioning. 14 (78% of these were located in the pancreatic head and uncinate process (P=0.09. The high grade (G3 lesions were significantly larger in size than the lower grade (G1 + G2 tumours (7.0 ± 3.5 cms versus 3.1 ± 1.6 cms, P=0.007. Pancreatoduodenectomy was performed in 18 (45%, distal pancreatectomy in 10 (25%, and local resection in 8 (20% and nonresective procedures were performed in 4 patients (10%. Fourteen patients (35% had postoperative complications. All G3 grade tumours which were resected had positive lymph nodes (100% and 10 had angioinvasion (71%. Eight neoplasms (20% were cystic, all being grade G3 carcinomas, while the rest were solid. The overall disease related mortality attributable to PEN was 14.3% (4 of 28 and for malignant PENs was 33.3% (4 of 12 after a mean follow-up period of 49.6 months (range: 2–137 months. Conclusion. Majority of PENs are nonfunctioning. They are more likely malignant if they are nonfunctioning and large in size, show cystic appearance, and are situated in the pancreatic head

Machined slices of lithium disilicate ceramic (LDC) (IPS e.max CAD) and feldspathic ceramic (FC) (VITA Mark II) glass ceramics were divided into two groups (n = 10) according to two factors: 1. surface treatment: HF+S (ca 5% hydrofluoric acid [IPS Ceramic Etching GEL] + silane coupling agent [SIL; Monobond Plus]) or MEP (single-component ceramic conditioner; Monobond Etch & Prime); 2. storage condition: baseline (without aging; tested 24 h after cementing) or aged (70 days of water storage + 12,000 thermal cycles). Composite cement (Multilink Automix, Ivoclar Vivadent) was applied to starch matrices on the treated ceramic surfaces and photoactivated. A μSBS test was performed (0.5 mm/min) and the failure pattern was determined. Contact angle and micromorphological analyses were also performed. Data were analyzed with Student's t-test (α = 5%). For both ceramic materials, HF+S resulted in higher mean μSBS (MPa) at baseline (LDC: HF+S 21.2 ± 2.2 > MEP 10.4 ± 2.4; FC: HF+S 19.6 ± 4.3 > MEP 13.5 ± 5.4) and after aging (LDC: HF+S 14.64 ± 2.31 > MEP 9 ± 3.4; FC HF+S: 14.73 ± 3.33 > MEP 11.1 ± 3.3). HF+S resulted in a statistically significant decrease in mean μSBS after aging (p = 0.0001), while MEP yielded no significant reduction. The main failure type was adhesive between composite cement and ceramic. HF+S resuted in the lowest contact angle. Hydrofluoric acid + silane resulted in higher mean μSBS than Monobond Etch & Prime for both ceramics; however, Monobond Etch & Prime had stable bonding after aging.

    It is known that single-cell genomics is a powerful tool for accessing genetic information from uncultivated microorganisms. Methods of handling samples before single-cell genomic amplification may affect the quality of the genomes obtained. Using three bacterial strains we demonstrate that, compared to cryopreservation, lower-quality single-cell genomes are recovered when the sample is preserved in ethanol or if the sample undergoes fluorescence in situ hybridization, while sample preservation in paraformaldehyde renders it completely unsuitable for sequencing.

    The effect of microwave radiation on the luminescence properties of CdS and CdTe:Cl single crystals is studied. It is established that the exposure of these semiconductors to short-term (≤30 s) microwave radiation substantially modifies their impurity and defect structure. The mechanisms of transformation of the defect subsystem of II–VI single crystals upon microwave treatment are discussed. It is shown that the experimentally observed changes are defined by the nonthermal effects of microwave radiation at a power density of 7.5 W cm –2 ; at 90 W cm –2 , nonthermal effects are prevailing

    Neves, Luis Filipe Ferreira

    To develop a therapeutic system with cancer cell selectivity, the present study evaluated a possible specific and localized tumor treatment. Phosphatidylserine (PS) exposure on the external face of the cell membrane is almost completely exclusive to cancer cells and endothelial cells in the tumor vasculature. The human protein annexin V is known to have strong calcium-dependent binding to anionic phospholipids such as PS. This protein was studied for targeting single-walled carbon nanotubes (SWNTs) to the vasculature of breast tumors. The synthesis of the protein annexin V, by a pET vector in Escherichia coli, constitutes the first phase of this study. Recombinant annexin V was purified from the cell lysate supernatant by immobilized metal affinity chromatography. The overall production of purified annexin V protein was 50 mg/L. The binding ability of the protein annexin V was evaluated by determining the dissociation constant when incubated with proliferating human endothelial cells in vitro. The dissociation constant, Kd, was measured to be 0.8 nM, indicating relatively strong binding. This value of Kd is within the range reported in the literature. Single-walled carbon nanotubes (SWNTs) were functionalized with annexin V using two intermediate linkers (containing FMOC and DSPE) resulting in stable suspensions. The SWNT and protein concentrations were 202 mg/L and 515 mg/L, respectively, using the linker with DSPE (average of nine preparations). The conjugation method that used the DSPE-PEG-maleimide linker allowed to successfully conjugate the SWNTs with final concentrations approximately five times higher than the linker containing FMOC. The conjugation method used has a non-covalent nature, and therefore the optical properties of the nanotubes were preserved. The conjugate was also visually observed using atomic force microscopy (AFM), allowing to verify the presence of the protein annexin V on the surface of the nanotubes, with an height ranging between 2

    A comparison of treatment parameters and quality of clinical outcome in patients with single brain metastases treated with two different technologies for radiosurgery (Gamma Knife and CyberKnife). Treatment parameters were statistically analyzed. Clinical outcome was assessed by matched-pair analysis based on the treatment device, differences in dose prescription, and the date of the treatment. Patients were matched according to their tumor size, age, gender, primary cancer, and Radiation Therapy Oncology Group score. Survival post-radiosurgery, local and distant tumor control, and complications were analyzed. Predictive factors were investigated. 423 single brain metastases were treated with Gamma Knife and 73 with CyberKnife. Tumor volumes were similar. The parameters minimum tumor dose, maximum tumor dose, prescription isodose volume, conformality index, homogeneity index, volume of tissue receiving a dose of 10 Gy or more were significantly larger in Gamma Knife group. Sixty-three patients were good matches. These showed the same pattern in parameters. Concerning the outcome analysis, only overall survival differed significantly between groups, twice as long with CyberKnife (P new brain metastases, including whole brain radiation therapy. The most important result of this study was the finding that the obvious differences in treatment-related parameters between Gamma Knife and CyberKnife had no impact on the quality of the clinical outcome after radiosurgery. Survival time increased chronologically, presumably due to an intensified anti-cancer therapy in the more recent era of the CyberKnife treatments.

    The aim of this study was to compare single dose oral azithromycin versus seven-day doxycycline in the treatment of non-gonococcal mucopurulent cervicitis (MPC). One hundred and thirty-one women with non-gonococcal MPC were enrolled in a prospective-randomised study to compare the efficacy and safety of a single oral dose of 1 g azithromycin and a seven-day course of 100 mg doxycycline twice daily. Clinical examination and culture samples for Chlamydia trachomatis and other microorganisms were performed before and approximately 14 days after starting the treatment. Of the 131 women recruited (67 in the azithromycin group and 64 in the doxycycline group), Ureaplasma urealyticum was isolated from 21 (16%); Chlamydia trachomatis from 15 (11.5%); and Mycoplasma hominis from 3 (2.3%) of the patients at the initial examination. The eradication rate of baseline culture-positive cases at the follow-up visit in the azithromycin group was 71.4%, and 77.3% in the doxycycline group. There was no statistically significant difference in efficacy between the single dose azithromycin and seven-day course of doxycycline in the treatment of culture-positive cases. Azithromycin 1 g appears to be an effective and safe alternative to doxycycline for the treatment of non-gonococcal MPC.

    Full Text Available Cutaneous metastasis of underlying primary malignancies can present to dermatologist with chief complaints of cutaneous lesions. The underlying malignancy is generally diagnosed much later after a complete assessment of the concerned case. Medullary carcinoma thyroid (MCT is a relatively uncommon primary neoplasia of the thyroid. Very few cases presenting as cutaneous metastases of MCT have been reported in the literature. Most of the cases which have been reported are of the papillary and the follicular types. We here report a case of a patient who presented in the dermatology clinic with the primary complaint of multiple subcutaneous nodules in anterior chest wall and left side of body of mandible. By systematic application of clinical and diagnostic skills these nodules were diagnosed as cutaneous metastasis of MCT bringing to the forefront a history of previously operated thyroid neoplasm. So clinically, the investigation of a flesh coloured subcutaneous nodule, presenting with a short duration, particularly in scalp, jaw, or anterior chest wall should include possibility of metastastic deposits. A dermatologist should keep a possibility of an internal organ malignancy in patients while investigating a case of flesh coloured subcutaneous nodules, presenting with short duration. A systematic application of clinical and diagnostic skills will eventually lead to such a diagnosis even when not suspected clinically at its primary presentation. A prompt and an emphatic diagnosis and treatment will have its bearing on the eventual outcome in all these patients.

    One third of infants with congenital hypogonadotropic hypogonadism (CHH) are said to have micropenis and/or bilateral or unilateral cryptorchidism leading many of them to orchiopexy. Our previous study in two patients suggests that prolonged subcutaneous infusion of large doses of gonadotropins might normalize testicular function and growth. To confirm the effects of early and prolonged subcutaneous infusion of large doses of gonadotropins on growth and descent of the testes. Eight boys with CHH, aged 0.25-11 months. Testes were non-palpable in 5 or in high scrotal position in 3. CHH was isolated in 5 infants and part of a syndrome of combined pituitary hormonal deficits in the 3 others. In response to gonadotropin infusion, mean levels of testicular hormones were normalized. Complete testis descent occurred in 6 patients. Partial descent occurred in 2. Testes re-ascended in 1 patient. Testes and penis gained normal dimensions in all cases. Subcutaneous gonadotropin infusion seems able to induce testis descent in a large proportion of infants with CHH. If confirmed, this may allow patients to avoid testes surgery but studies in larger series are needed to evaluate the benefits of this treatment versus traditional orchiopexy.

    Full Text Available Background: Neurologic literature on therapeutic effect of subcutaneous corticosteroids in patients with migrainous chronic daily headache is scarce. The aim of this research is to assess the therapeutic effects of this management in such patients. Methods: Consecutive patients with migrainous chronic daily headache enrolled a prospective before-after therapeutic study during 2010-2013. Methylprednisolone 40 mg was divided into four subcutaneous injection doses. Two injections were administered in the right and left suboccipital area (exactly at retromastoid cervicocranial junction and the other two injections in the lower medial frontal area (exactly at medial right and left eyebrows. A daily headache diary was filled out by the patients before and one month after the intervention. The severity of pain was classified based on a pain intensity instrument using numeric rating scale from 0-10 point scale. Paired t-test and Chi-square test were used for statistical analysis. Results: 504 patients (378 females, 126 males with migrainous chronic daily headache were enrolled in the study. Dramatic, significant, moderate, mild, or no improvements respectively constituted 28.6%, 33.3%, 23.8%, and 14.3% of the post treatment courses. Therapeutic effect of intervention on mean pain scores was significant; t=7.38, df=20, P=0.000. Two cases developed subcutaneous fat atrophy in frontal injection site and three cases experienced syncope during injection. Conclusion: Subcutaneous corticosteroids could be used as an adjunct therapy in patients with migrainous chronic daily headache.

    To compare the impact of a single fraction (8 Gy x 1 fraction) and multifraction (3 Gy x 10 fractions) radiotherapy regimens on pain relief, recalcification and the quality of life (QoL) in patients with bone destructions due to multiple myeloma (MM). In all, 101 patients were included in a randomised prospective clinical trial: 58 patients were included in the control arm (3 Gy x 10 fractions) and 43 patients into the experimental arm (8 Gy x 1 fraction). The response rate was defined according to the International Consensus on Palliative Radiotherapy criteria. Recalcification was evaluated with radiographs. QoL questionnaires were completed before and 4 weeks after treatment. Pain relief was obtained in 81/101 patients (80.2%): complete response in 56 (69%) and partial in 25 patients (30.9%). No significant differences were observed in analgesic response between the groups. Significant factors for pain relief were female gender, age under 65, IgG MM type, presence of recalcification at the irradiated site. Recalcification was found in 32/101 patients (33.7%): complete in 17 (53.2%) and partial in 15 (46.2%). No significant differences were observed in recalcification between the groups. Significant factors for recalcification were Karnofsky index ≥ 60%, haemoglobin level ≤ 80 g/dl, MM stage II and analgesic response at the irradiated site. The QoL after radiotherapy was improved in the control group. The same analgesic and recalcification response was observed using two different radiotherapy regimens. Higher doses should be used to achieve a better QoL. (orig.)

    Full Text Available Three types of post-weld heat treatment (PWHT, i.e. solution treatment + primary aging + secondary aging (I, secondary aging (II, and primary aging + secondary aging (III, were applied to a single crystal nickel-based superalloy joint made with linear friction welding (LFW. The results show that the grains in the thermomechanically affected zone (TMAZ coarsen seriously and the primary γ' phase in the TMAZ precipitates unevenly after PWHT I. The primary γ' phase in the TMAZ and weld zone (WZ precipitates insufficiently and fine granular secondary γ' phase is observed in the matrix after PWHT II. After PWHT III, the primary γ' phase precipitates more sufficiently and evenly compared to PWHTs I and II. Moreover, the grains in the TMAZ have not coarsened seriously and fine granular secondary γ' phase is not found after PWHT III. PWHT III seems more suitable to the LFWed single crystal nickel-based superalloy joints when performing PWHT.

    2015-08-01

    Full Text Available BackgroundTranscranial direct current stimulation (tDCS, a non-invasive method of brain stimulation, is an adjunctive research-therapy for aphasia. The concept supporting translational application of tDCS is that brain plasticity, facilitated by language intervention, can be enhanced by non-invasive brain stimulation. This study combined tDCS with an ecologically-focused behavioral approach that involved training nouns and verbs in sentences. MethodParticipant: A 43-year-old, right-handed male with fluent-anomic aphasia who sustained a single-left-hemisphere-temporal-parietal stroke was recruited. Treatment: Instrumentation included the Soterix Medical 1x1 Device. Anodal tDCS was applied over Broca’s area. Behavioral materials included: sentence production, naming in the sentence context, and implementation of a social-conversational-discourse treatment.Design and Procedures: The independent variable of this crossover case-study was tDCS, and the dependent variables were language and quality-of-life measures. In each session the subject received language treatment with the first twenty minutes additionally including tDCS. ResultsPerformance in naming nouns and verbs in single words and sentences were obtained. Verb production in the sentence context increased after active anodal tDCS and speech-language treatment. ConclusionAphasia treatment that involves naming in the sentence context in conjunction with translational application of tDCS may be a promising approach for language-recovery post stroke.

    The advantages of reduced-port laparoscopic surgery (RPLS) for rectosigmoid cancer treatment have been disputed. This study evaluated the outcomes of RPLS compared to conventional laparoscopic surgery (CLS) for rectosigmoid cancer. Data from 211 patients who underwent a selective sigmoidectomy or anterior resection from August 2011 to June 2014 at a single institution were collected and analyzed via propensity score matching. Operative outcomes, inflammatory responses, pain intensity, oncologic outcomes, quality of life, and cosmetic results were compared between groups. After matching, 96 patients (48 CLS and 48 RPLS) were evaluated. Sixteen RPLS cases underwent single-incision laparoscopic surgery (SILS), and 32 underwent single-incision plus one port laparoscopic surgery (SILS + 1). Baseline clinical characteristics were comparable between the RPLS and the CLS groups. Morbidity, pathologic outcomes, and 3-year disease-free survival and overall survival rates were also comparable between the 2 groups. Compared with the CLS group, the RPLS group had a shorter total incision length (p time to liquid diet (p = 0.027), ambulation (p = 0.026), and discharge (p times, C-reactive protein levels at 24 h and 96 h, and interleukin-6 levels at 24 h postoperatively were significantly lower in the SILS + 1 group than those in the CLS and SILS groups (p cosmetic results, and both groups showed better results than the CLS group (p < 0.001). RPLS for rectosigmoid cancer is feasible, with short-term safety and long-term oncological safety comparable to that of CLS. Better cosmesis and accelerated recovery can be expected. SILS + 1 is a better choice than CLS or SILS for rectosigmoid cancer because it minimizes invasiveness and reduces technical difficulties.

    2014-01-01

    Abstract Purpose: To demonstrate that ultraviolet-A (UV-A) and voriconazole combination therapy is more effective than voriconazole single treatment for fungal keratitis. Methods: The in vitro UV-A (375 nm) fungicidal effect was evaluated on Fusarium solani solutions. Each fungal solution was irradiated with different UV-A irradiation doses. Also, a fungal solution containing voriconazole was also irradiated with UV-A. The in vivo therapeutic effect of UV-A and voriconazole treatment was studied in a rabbit keratitis model. Fungi were injected intrastromally into the cornea of 16 rabbits. Each treatment was initiated 3 days after fungal injection and continued up to 8 days for the following groups: Group 1, control; Group 2, treated with UV-A once a day; Group 3, treated with voriconazole 3 times a day; Group 4, treated with voriconazole 3 times a day and UV-A once a day. On the last day, the sclera–cornea buttons were extracted and microbiological and histological evaluations were performed. Results: The colony-forming units (CFUs) of fungal solutions in culture significantly decreased with UV-A irradiation. The CFUs of fungal solutions containing voriconazole also decreased with UV-A irradiation. In vivo, clinical scores of Group 3 (P=0.03) and Group 4 (P=0.02) 5 days after treatment were significantly lower compared to that of Group 1. The clinical score of Group 4 (P=0.03) 5 days after treatment was significantly lower compared to that of Group 3. The histopathological scores 5 days after treatment were significantly lower in Group 4 compared to those of Group 1 (Pvoriconazole combination treatment could be a safe and effective alternative to voriconazole single treatment for fungal keratitis.

    Akhil Kapoor

    2015-01-01

    Full Text Available Background: Bone metastasis is a usual cause of pain in advanced cancer. Conventional radiation schedules require larger hospital stay and thus are not suitable for patients with poor general condition. This prospective observational study aims to compare the pain-relieving efficacy of different radiation fractionation schedules, i.e., 8 Gy administered in a single fraction versus 30 Gy administered in 10 fractions. Materials and Methods: Two hundred and fifty consecutive patients of bone metastasis were evaluated for the study, with 63 patients being excluded due to non-fulfillment of the inclusion criteria. The response to radiotherapy leading to pain relief as per the Visual Analog Scale was recorded at the end of treatment, 8 days, 15 days and 1 month during the follow-up visits. Results: Sixty-two percent of the patients received a single fraction while the remaining received 10 fractions. In the 10-fraction group, overall response was present in 60% of the patients. Stable pain was present in 23% of the patients while 9% patients had progressive pain. At 1 month of completion of treatment, 9% patients were lost to follow-up. In the single-fraction arm, overall response was seen in 58%, stable pain in 27% and progressive pain in 7% of the patients. Six percent of the patients were lost to follow-up. Conclusions: Single-fraction treatment for bony metastasis is as effective as multiple fractions to relieve bony pain and provides treatment convenience to both the patient and the caregiver.

    Previous genetic and proteomic studies identified altered activity of various enzymes such as those of fatty acid metabolism and glycogen synthesis after a single toxic dose of valproic acid (VPA) in rats. In this study, we demonstrate the effect of VPA on metabolite synthesis flux rates and the possible use of abnormal (13)C labeled glucose-derived metabolites in plasma or urine as early markers of toxicity. Female CD-1 mice were injected subcutaneously with saline or 600 mg/kg) VPA. Twelve hours later, the mice were injected with an intraperitoneal load of 1 g/kg [U-(13)C]-d-glucose. (13)C isotopomers of glycogen glucose and RNA ribose in liver, kidney and brain tissue, as well as glucose disposal via cholesterol and glucose in the plasma and urine were determined. The levels of all of the positional (13)C isotopomers of glucose were similar in plasma, suggesting that a single VPA dose does not disturb glucose absorption, uptake or hepatic glucose metabolism. Three-hour urine samples showed an increase in the injected tracer indicating a decreased glucose re-absorption via kidney tubules. (13)C labeled glucose deposited as liver glycogen or as ribose of RNA were decreased by VPA treatment; incorporation of (13)C via acetyl-CoA into plasma cholesterol was significantly lower at 60 min. The severe decreases in glucose-derived carbon flux into plasma and kidney-bound cholesterol, liver glycogen and RNA ribose synthesis, as well as decreased glucose re-absorption and an increased disposal via urine all serve as early flux markers of VPA-induced adverse metabolic effects in the host.

    Non-invasive fat removal is preferred because of decreased downtime and lower perceived risk. It is important to seek new non-invasive fat removal treatments that are both safe and efficacious. To assess the extent to which carboxytherapy, the insufflation of carbon dioxide gas into subcutaneous fat, results in reduction of fat volume. Randomized, sham-controlled, split-body study. Adults (BMI 22-29) were randomized to receive five weekly infusions of 1000 cc CO 2 to one side of the abdomen, and five sham treatments to the contralateral side. Primary outcome measures were ultrasound measurement of fat layer thickness, as well as total circumference before and after treatment. Sixteen participants completed the study. Ultrasound measurement indicated less fat volume on the sides treated with carboxytherapy one week after the last treatment, (p=0.011), but was not maintained at 28 weeks. Total circumference decreased nominally but not significantly at Week 5 compared to baseline (p=0.0697). Participant body weights did not change over the entire course of the study (p=1.00) LIMITATIONS: Limitations included modest sample size and some sources of error in circumference and fat layer measurements. Carboxytherapy provides a transient decrease in subcutaneous fat that may not persist. Treatment is well-tolerated. Copyright © 2018. Published by Elsevier Inc.

    The abdominal subcutaneous adipose tissue blood flow (ATBF) was measured bilaterally by the 133Xe washout method. At one side of the skin (epicutaneous) temperature was varied with a temperature blanket, the other side served as control. There was a significant (P less than 0.001) positive...... correlation between skin temperature and ATBF. In the range from 25 to 37 degrees CATBF increased 9% of the control flow on average per centigrade increase in skin temperature. ATBF at the control side was uninfluenced by the contralateral variations in skin temperature. Although no better correlation could...... be demonstrated between ATBF and subcutaneous temperature than between ATBF and skin temperature, arguments are presented in favour of the hypothesis that ATBF is influenced by the subcutaneous temperature rather than via reflexes from the skin.

    1991-03-01

    This is a three case study report of children with measles which later progressed to bronchopneumonia and subcutaneous emphysema. All three children were from farming families, and none had been previously vaccinate against measles. For a period of six months, 183 cases of measles were treated at our hospital of which only three worsened to subcutaneous emphysema, demonstrating an incidence rate of 1.6%; they also showed to have bronchopneumonia, with severe coughing episodes; which made us recall the possible physiopathology principle of the pressure gradient theory behind this complication proposed by Bloch in 1968. The factors related to our patients suggested a more severe and aggresive type of measles with a greater probability of having complications. The prognostic value of the severity of this type of measles in the presence of subcutaneous emphysema is limited and its management should be primarly focused on treating the added bronchial problem.

    Nonadherence to treatment regimens for immunosuppressive agents is one of the major risk factors for allograft failure in kidney transplant recipients. The aim of this study was to estimate the relative effect of daily dosing on treatment adherence, not to identify how patients are non-adherent, in long-term kidney transplant recipients. In January 2009, a cross-sectional, anonymous, and voluntary questionnaire survey was given to kidney transplant recipients who regularly visited Inoue Hospital. A self-reporting questionnaire underestimates nonadherence, but we reasoned that the effect of the dosing regimen should be estimated with relative accuracy by using the generalized ordered logit/partial proportional hazard odds model given that the distribution patterns in the degree of nonadherence have been shown to be similar with other measures. Of 336 eligible patients, 312 (92.9 %) participated in this study. Two hundred seventy-four patients (87.8 %) were more than 3 years post-transplant. Univariate analysis revealed that a single daily dose was significantly associated with better adherence. After controlling for age, sex, time since transplantation, and the number of prescribed drugs, the effect of a single daily dose still remained significant [odds ratio, 0.40 (95 % confidence interval, 0.19-0.81); p = 0.011]. Several sensitivity analyses yielded similar results. To our knowledge, this is the first report that, in long-term kidney transplant recipients, a single daily regimen-one of few modifiable factors-might improve treatment adherence and allograft survival.

    The efficacy and safety of a florfenicol plus flunixin meglumine formulation in the treatment of respiratory disease was evaluated in calves less than six weeks of age, compared with a positive control group treated with a well-established florfenicol formulation. A total of 210 calves, selected from nine sites in Belgium, France and Spain, showing severe signs of respiratory disease, were randomly assigned to treatment with either florfenicol plus flunixin meglumine (Resflor; MSD Animal Health) or florfenicol (Nuflor; MSD Animal Health), both administered subcutaneously once. Animals were clinically observed daily for 10 days following treatment initiation. The predominant respiratory pathogens were Pasteurella multocida, Mycoplasma bovis, Mannheimia haemolytica and Histophilus somni. All isolates were subject to in vitro sensitivity testing and found susceptible to florfenicol. In both groups, rectal temperature dropped and clinical index (depression and respiratory signs) significantly improved after treatment. Specifically, for the change in rectal temperature from pretreatment to six hours post-treatment, the florfenicol-flunixin formulation was found significantly superior to florfenicol. Moreover, the florfenicol-flunixin formulation alleviated the clinical signs of disease more rapidly, and was demonstrated to be non-inferior to florfenicol on days 4 and 10. The use of the product combining florfenicol and flunixin in calves is safe and efficacious in the treatment of outbreaks of bovine respiratory disease.

    The experiments - published in 7 papers in The Journal of Investigative Dermatology 1983-86 - have demonstrated: 1. The accuracy of the local 133 Xe washout method is about 15% for estimation of the cutaneous blood flow (CBF), and about 10% for subcutaneous blood flow measurements (SBF). In measurements of absolute CBF values a graphic curve resolution of the washout curve should alwaus be performed. Otherwise the CBF might be considerably underestimated. 2. CdTe(Cl) mini-detectors can be attached directly to the skin, and might yield measurements of both CBF and SBF that can substitute for those made with conventional detectors. 3. The laser Doppler measurements could not be correlated to quantitative measurements of the CBF. 4. The tissue-to-blood partition coefficient for 133 Xe of lesional psoriatic skin (LS) is increased. 5. In untreated, LS of patients with active psoriasis the CBF is about a factor of 10 times higher than the CBF of normal individuals. In non-lesional skin (NLS) of patients with active psoriasis the CBF is about a factor of 2 higher than the CBF of normal individuals. However, the CBF did not differ in NLS of patients with minimal skin manifestations. The high CBF decreases gradualy during antipsoriatic treatment. 6. A paradoxical autoregulation of the CBF was observed in LS. 7. The high CBF is not due to a maximally dilated vascular bed. 8. The SBF in LS areas was a factor of higher than the SBF in normal individuals. 9. A normal, local regulation of the SBF was found. (author)

    Allergy immunotherapy is an effective way to manage the allergic patient and may be administered either through the subcutaneous route (SCIT) or the sublingual route (SLIT). Both have been proven efficacious; however, SLIT is currently not covered by insurance companies and is an out-of-pocket expense. The goal of the current study is to compare the costs of SCIT to SLIT. For SCIT, a total of 9 different insurance groups were studied including 8 preferred provider organizations (PPOs) and Medicare. Costs were broken down according to the percentage of coverage for the injections, serum vial fees, weekly co-pay, and deductibles. Total yearly cost for SCIT was calculated for the varying insurance plans and compared to the yearly cost of SLIT. PPO plans covered between 60% and 100% of allergy immunotherapy treatment with a range of weekly co-pay between $0 and $50. Deductibles ranged between $0 and $7000. Medicare had a flat rate of 80% coverage costing the insurer $807.20 for the year of therapy. None of the above costs include loss of work productivity and travel expense. The cost of SLIT ranged from $500 to $2100 depending on the allergy practice and number on antigens treated. The cost of SCIT varies dramatically according to insurance plan whereas the cost of SLIT varies between practices. When loss of productivity and travel expense are added into the cost of SCIT, SLIT might be comparable in cost and more convenient for the patient. Although the lack of insurance coverage for SLIT currently makes it more expensive than SCIT, we have found that the financial gap is much smaller than initially thought, especially when indirect costs and plans with less than 80% coverage or high weekly co-pay are factored into the equation.

    Full Text Available OBJECTIVE: To investigate the secondary progressive multiple sclerosis (SPMS patients treated with mitoxantrone (MIT and discuss the effectiveness and side effects of MIT. METHODS: We retrospectively investigated 48 SPMS patients who completed or were still receiving MIT treatment. Expanded Disability Status Scale (EDSS scores of the patients were determined who had detailed examination before the treatment. Complete blood count, urine examination, chest x-ray, kidney and liver function tests, transthoracic echocardiography were performed at initiation and during follow-up and 10 mg/m2 MIT was administered every three months. The data were assessed in order to determine the effectiveness and side effects. RESULTS: A total of 48 patients, 34 women and 14 men, had an age of 42 (26-55 years at the initiation of MIT treatment. The duration of the treatment was 12 (3-30 months. The median EDSS scores were 6 (4-8 before the treatment and 6 (4-9 after the treatment. EDSS scores improved in 6 patients, deteriorated in 12 patients and 30 patients remained with stable EDSS scores during the treatment. Seventeen patients had no side effects however 31 patients developed side effects. CONCLUSION: On the basis of this study, which is a clinical assessment of the effectiveness and side effects of MIT, we conclude that MIT can limit disability in SPMS patients and it is useful in treating SPMS patients due to favorable risk-benefit ratio

    To determine if the metronidazole (MTZ) 2-gm single dose (recommended) is as effective as the 7-day 500 mg twice a day dose (alternative) for treatment of Trichomonas vaginalis (TV) among HIV+ women. Phase IV randomized clinical trial; HIV+ women with culture confirmed TV were randomized to treatment arm: MTZ 2-gm single dose or MTZ 500 mg twice a day 7-day dose. All women were given 2-gm MTZ doses to deliver to their sex partners. Women were recultured for TV at a test-of-cure (TOC) visit occurring 6-12 days after treatment completion. TV-negative women at TOC were again recultured at a 3-month visit. Repeat TV infection rates were compared between arms. Two hundred seventy HIV+/TV+ women were enrolled (mean age = 40 years, ±9.4; 92.2% African American). Treatment arms were similar with respect to age, race, CD4 count, viral load, antiretroviral therapy status, site, and loss-to-follow up. Women in the 7-day arm had lower repeat TV infection rates at TOC [8.5% (11 of 130) versus 16.8% (21 of 125) (relative risk: 0.50, 95% confidence interval = 0.25, 1.00; P TV among HIV+ women.

    One of the most direct means for human exposure to nanoparticles (NPs) released into the environment is drinking water. Therefore, it is critical to understand the occurrence and fate of NPs in drinking water systems. The objectives of this study were to develop rapid and reliable analytical methods and apply them to investigate the fate and transportation of NPs during drinking water treatments. Rapid single particle ICP-MS (SP-ICP-MS) methods were developed to characterize and quantify titanium-containing, titanium dioxide, silver, and gold NP concentration, size, size distribution, and dissolved metal element concentration in surface water and treated drinking water. The effectiveness of conventional drinking water treatments (including lime softening, alum coagulation, filtration, and disinfection) to remove NPs from surface water was evaluated using six-gang stirrer jar test simulations. The selected NPs were nearly completely (97 ± 3%) removed after lime softening and alum coagulation/activated carbon adsorption treatments. Additionally, source and drinking waters from three large drinking water treatment facilities utilizing similar treatments with the simulation test were collected and analyzed by the SP-ICP-MS methods. Ti-containing particles and dissolved Ti were present in the river water samples, but Ag and Au were not present. Treatments used at each drinking water treatment facility effectively removed over 93% of the Ti-containing particles and dissolved Ti from the source water. Copyright © 2015 Elsevier Ltd.

    Preliminary results have shown that bioelectrical impedance measurements performed on different parts of the human body strongly depend upon the subcutaneous fat of the considered region. In this work, a method for the determination of subcutaneous fat thickness is explored. Within this method the measurement of the bioelectrical impedance response of the fat-muscle system, both along the direction defined by the muscle fibers and along the corresponding perpendicular direction, are performed. Measurements have been carried out on human female and male subjects of ages around 25 years old at the region of the biceps. Correlation has been performed with skinfold caliper measurements.

  15. Subcutaneous preconditioning increases invasion and metastatic dissemination in mouse colorectal cancer models

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available Mouse colorectal cancer (CRC models generated by orthotopic microinjection of human CRC cell lines reproduce the pattern of lymphatic, haematological and transcoelomic spread but generate low metastatic efficiency. Our aim was to develop a new strategy that could increase the metastatic efficiency of these models. We used subcutaneous implantation of the human CRC cell lines HCT116 or SW48 prior to their orthotopic microinjection in the cecum of nude mice (SC+ORT. This subcutaneous preconditioning significantly enhanced metastatic dissemination. In the HCT116 model it increased the number and size of metastatic foci in lymph nodes, lung, liver and peritoneum, whereas, in the SW48 model, it induced a shift from non-metastatic to metastatic. In both models the number of apoptotic bodies in the primary tumour in the SC+ORT group was significantly reduced compared with that in the direct orthotopic injection (ORT group. Moreover, in HCT116 tumours the number of keratin-positive tumour buddings and single epithelial cells increased at the invasion front in SC+ORT mice. In the SW48 tumour model, we observed a trend towards a higher number of tumour buds and single cells in the SC+ORT group but this did not reach statistical significance. At a molecular level, the enhanced metastatic efficiency observed in the HCT116 SC+ORT model was associated with an increase in AKT activation, VEGF-A overexpression and downregulation of β1 integrin in primary tumour tissue, whereas, in SW48 SC+ORT mice, the level of expression of these proteins remained unchanged. In summary, subcutaneous preconditioning increased the metastatic dissemination of both orthotopic CRC models by increasing tumour cell survival and invasion at the tumour invasion front. This approach could be useful to simultaneously study the mechanisms of metastases and to evaluate anti-metastatic drugs against CRC.

    The aim of this study was to investigate the efficacy, and the safety of systemic multidose methotrexate (MTX) for the treatment of cesarean scar pregnancy (CSP). This retrospective cohort study was performed using records from the Department of Obstetrics and Gynecology, Erciyes University, between 2010 and 2012. The data were analyzed with respect to obstetric characteristic, course of treatment, clinical, and reproductive outcomes. A total of 13 patients were evaluated. The median gestational age at diagnosis was 5 weeks 5 days (range: 4-9 weeks). The mean beta human chorionic gonadotrophin level was 11,240.31 ± 9812.68 IU/L (range: 2565-36,111 IU/L). All patients were successfully treated with systemic multidose MTX therapy. The average MTX dose was 5.7 (range: 2-9). The interval between the first MTX injection and the normalization of beta human chorionic gonadotrophin was 8 ± 2.27 weeks (range: 4-12 weeks). One patient showed mild leucopenia that reversed after the treatment. Three patients had successful uncomplicated intrauterine pregnancy after the treatment, which resulted in term infants. Systemic multidose MTX therapy is an effective and safe treatment method for CSP. However, further studies are needed to compare the safety, effectiveness and reproductive outcome of different treatment modalities in CSP. © 2014 The Authors.

    Four dimensional computed tomography (4DCT) scans are routinely used in radiation therapy to determine the internal treatment volume for targets that are moving (e.g. lung tumors). The use of these studies has allowed clinicians to create target volumes based upon the motion of the tumor during the imaging study. The purpose of this work is to determine if a target volume based on a single 4DCT scan at simulation is sufficient to capture thoracic motion. Phantom studies were performed to determine expected differences between volumes contoured on 4DCT scans and those on the evaluation CT scans (slow scans). Evaluation CT scans acquired during treatment of 11 patients were compared to the 4DCT scans used for treatment planning. The images were assessed to determine if the target remained within the target volume determined during the first 4DCT scan. A total of 55 slow scans were compared to the 11 planning 4DCT scans. Small differences were observed in phantom between the 4DCT volumes and the slow scan volumes, with a maximum of 2.9%, that can be attributed to minor differences in contouring and the ability of the 4DCT scan to adequately capture motion at the apex and base of the motion trajectory. Larger differences were observed in the patients studied, up to a maximum volume difference of 33.4%. These results demonstrate that a single 4DCT scan is not adequate to capture all thoracic motion throughout treatment.

    In consultation, school psychologists may offer educators direct training to support the implementation of classroom interventions aimed to improve student outcomes. The purpose of this study was to conduct a systematic literature review of single-case design research studies during which educators received direct training to implement a classroom intervention, specifically instructions, modeling, practice, and feedback. Two doctoral students in school psychology screened 228 articles and evaluated 33 studies to determine if direct training is effective and an evidence-based practice per single-case design standards proposed by the What Works Clearinghouse. Results of the review indicate that there is support for the practice to be deemed evidence-based and associated with better intervention implementation than before its application. Implications include direct training being considered for intensive, complex interventions to promote educator success with implementation.

    2006-01-01

    Purpose: The specific aim of this study was to evaluate outcome differences by gender and partner status for patients treated on Radiation Therapy Oncology Group (RTOG) protocol 97-14. Methods and Materials: RTOG 97-14 randomized patients with metastatic breast or prostate cancer to bone to receive 8 Gy in 1 fraction or 30 Gy in 10 fractions. Retreatment rates and overall survival were made based upon gender, marital status, and Karnofsky Performance Status (KPS). The cumulative incidence method was used to estimate retreatment time at 36 months from enrollment, and Gray's test was used to test for treatment differences within the same groupings. Marital status, gender, KPS, and treatment were variables tested in a univariate Cox model evaluating the time to retreatment. Results: Married men and women and single women receiving 30 Gy had significantly longer time to retreatment, p = 0.0067, p = 0.0052, and p = 0.0009 respectively. We failed to show a difference in retreatment rates over time in single men receiving either 30 Gy or 8 Gy. Univariate analysis of the entire group determined patients receiving 30 Gy in 10 fractions significantly less likely to receive retreatment, p < 0.0001, with a trend toward single patients less likely to be re-treated, p = 0.07. Conclusion: Non-disease-related variables, such as social support, might influence the results of clinical trials with subjective endpoints such as retreatment rates. The statistically nonsignificant difference in the 36-month retreatment rates observed in single male patients receiving 8 Gy may be a result of inadequate social support systems in place to facilitate additional care. Patients receiving 8 Gy in a single fraction had significantly higher retreatment rates compared with patients receiving 30 Gy in 10 fractions

  2. Antiangiogenic agents in the treatment of recurrent or newly diagnosed glioblastoma: Analysis of single-agent and combined modality approaches

    Surgical resection followed by radiotherapy and temozolomide in newly diagnosed glioblastoma can prolong survival, but it is not curative. For patients with disease progression after frontline therapy, there is no standard of care, although further surgery, chemotherapy, and radiotherapy may be used. Antiangiogenic therapies may be appropriate for treating glioblastomas because angiogenesis is critical to tumor growth. In a large, noncomparative phase II trial, bevacizumab was evaluated alone and with irinotecan in patients with recurrent glioblastoma; combination treatment was associated with an estimated 6-month progression-free survival (PFS) rate of 50.3%, a median overall survival of 8.9 months, and a response rate of 37.8%. Single-agent bevacizumab also exceeded the predetermined threshold of activity for salvage chemotherapy (6-month PFS rate, 15%), achieving a 6-month PFS rate of 42.6% (p < 0.0001). On the basis of these results and those from another phase II trial, the US Food and Drug Administration granted accelerated approval of single-agent bevacizumab for the treatment of glioblastoma that has progressed following prior therapy. Potential antiangiogenic agents-such as cilengitide and XL184-also show evidence of single-agent activity in recurrent glioblastoma. Moreover, the use of antiangiogenic agents with radiation at disease progression may improve the therapeutic ratio of single-modality approaches. Overall, these agents appear to be well tolerated, with adverse event profiles similar to those reported in studies of other solid tumors. Further research is needed to determine the role of antiangiogenic therapy in frontline treatment and to identify the optimal schedule and partnering agents for use in combination therapy

    High dose rate (HDR) brachytherapy treatment planning is conventionally performed manually and/or with aids of preplanned templates. In general, the standard of care would be elevated by conducting an automated process to improve treatment planning efficiency, eliminate human error, and reduce plan quality variations. Thus, our group is developing AutoBrachy, an automated HDR brachytherapy planning suite of modules used to augment a clinical treatment planning system. This paper describes our proof-of-concept module for vaginal cylinder HDR planning that has been fully developed. After a patient CT scan is acquired, the cylinder applicator is automatically segmented using image-processing techniques. The target CTV is generated based on physician-specified treatment depth and length. Locations of the dose calculation point, apex point and vaginal surface point, as well as the central applicator channel coordinates, and the corresponding dwell positions are determined according to their geometric relationship with the applicator and written to a structure file. Dwell times are computed through iterative quadratic optimization techniques. The planning information is then transferred to the treatment planning system through a DICOM-RT interface. The entire process was tested for nine patients. The AutoBrachy cylindrical applicator module was able to generate treatment plans for these cases with clinical grade quality. Computation times varied between 1 and 3 min on an Intel Xeon CPU E3-1226 v3 processor. All geometric components in the automated treatment plans were generated accurately. The applicator channel tip positions agreed with the manually identified positions with submillimeter deviations and the channel orientations between the plans agreed within less than 1 degree. The automatically generated plans obtained clinically acceptable quality.

    Despite the availability of multiple disease-modifying therapies for relapsing multiple sclerosis (MS), there remains a need for highly efficacious targeted therapy with a favorable benefit–risk profile and attributes that encourage a high level of treatment adherence. Daclizumab is a humanized monoclonal antibody directed against CD25, the α subunit of the high-affinity interleukin 2 (IL-2) receptor, that reversibly modulates IL-2 signaling. Daclizumab treatment leads to antagonism of proinflammatory, activated T lymphocyte function and expansion of immunoregulatory CD56bright natural killer cells, and has the potential to, at least in part, rectify the imbalance between immune tolerance and autoimmunity in relapsing MS. The clinical pharmacology, efficacy, and safety of subcutaneous daclizumab have been evaluated extensively in a large clinical study program. In pivotal studies, daclizumab demonstrated superior efficacy in reducing clinical and radiologic measures of MS disease activity compared with placebo or intramuscular interferon beta-1a, a standard-of-care therapy for relapsing MS. The risk of hepatic disorders, cutaneous events, and infections was modestly increased. The monthly subcutaneous self-injection dosing regimen of daclizumab may be advantageous in maintaining patient adherence to treatment, which is important for optimal outcomes with MS disease-modifying therapy. Daclizumab has been approved in the US and in the European Union and represents an effective new treatment option for patients with relapsing forms of MS, and is currently under review by other regulatory agencies.

    Low megavolt electron beam irradiation was used on 354 sites in 199 patients at Lahey Clinic either for palliation of symptomatic hypertrophic scars or as post operative irradiation in an attempt to prevent formation or recurrence of hypertrophic scars. Electron energies used ranged from 1.5 to 3.5 MeV. The median age of the 59 male patients was 22 years and of the 140 female patients 35 years. All patients had at least one follow-up visit, and the median follow-up was 35 months. Of the 294 sites treated for the first time, 272 (93 per cent) were irradiated with a single fraction with a skin dose ranging from 2 to 20 Gy. Of the 85 sites in 63 patients without excision of symptomatic hypertrophic scars, single-dose electron beam irradiation was of clinically significant value in only 41 sites (48 per cent). No patients have been treated without surgical excision since 1973. Because of a history of formation of hypertrophic scars elsewhere in the body, 13 patients with 19 incisions were treated prophylactically after operation for other diseases. All sites were irradiated with single doses ranging from 8 to 20 Gy, and hypertrophic scars did not subsequently develop in any patient. Altogether, 119 patients with 174 sites were irradiated after surgical excision of hypertrophic scars to prevent recurrence; 168 sites (97 per cent) received singe-fraction irradiation, and 161 received a dose of 8 Gy greater, up to 15 Gy. No statistically significant differences were observed in complete success rates, ranging from 82 to 90 per cent with doses of 9 Gy or greater. An interval of up to 72h between excision and single-fraction irradiation satisfactorily prevented recurrence, and clinically significant chronic telangiectasia was recorded in only one patient. Postoperative low megavolt electron beam irradiation with a single dose of 9 Gy or greater is highly effective in the prevention of formation recurrence of hypertrophic scars or keloids.

    Pemphigus vulgaris (PV) is a chronic autoimmune blistering disease. Most patients require long-term therapy with systemic steroids, and a steroid-sparing agent is usually also utilized. Dapsone is a chemotherapeutic agent with anti-inflammatory properties that is used as a steroid-sparing agent in PV. The aim of the present study was to evaluate the efficacy of dapsone as an adjuvant therapy in patients with PV. A retrospective analysis of patients' files was performed. All 26 patients included in the study group were treated with dapsone as an adjuvant to systemic steroids for at least 3 consecutive months and were followed up during their dapsone treatment period. After 3 months of treatment with dapsone, 13 patients were in the consolidation phase, 4 patients demonstrated partial remission on minimal therapy, 7 patients demonstrated complete remission on minimal therapy, and 2 patients were defined as treatment failures. The trend of clinical improvement continued after 6 months of treatment and at the study end point. This retrospective case series, one of the largest reported, indicates that dapsone is efficacious and safe for patients with PV in whom it is well tolerated soon after the initiation of treatment. © 2016 S.

    The objective of this work was to determine the dynamics of maximal anaerobic power (MAP) of the lower limbs, following a single whole body cryostimulation treatment (WBC), in relation to the temperature of thigh muscles. The subjects included 15 men and 15 women with an average age (± SD) of 21.6 ± 1.2 years. To evaluate the level of anaerobic power, the Wingate test was applied. The subjects were submitted to 6 WBC treatments at -130°C once a day. After each session they performed a single Wingate test in the 15, 30, 45, 60, 75 and 90th min after leaving the cryogenic chamber. The order of the test was randomized. All Wingate tests were preceded by an evaluation of thigh surface temperature with the use of a thermovisual camera. The average thigh surface temperature (T(av)) in both men and women dropped significantly after the whole body cryostimulation treatment, and next increased gradually. In women T(av) remained decreased for 75 min, whereas in men it did not return to the basal level until 90th min. A statistically insignificant decrease in MAP was observed in women after WBC. On the contrary, a non-significant increase in MAP was observed in men. The course of changes in MAP following the treatment was similar in both sexes to the changes in thigh surface temperature, with the exception of the period between 15th and 30th min. The shorter time to obtain MAP was observed in women till 90th min and in men till 45 min after WBC compared to the initial level. A single whole body cryostimulation may have a minor influence on short-term physical performance of supramaximal intensity, but it leads to improvement of velocity during the start as evidenced by shorter time required to obtain MAP.

    Immunotherapy has shown to be an effective treatment for the management of some IgE-mediated allergies. However, due to its long duration, a high number of patients withdraw from it before completion. Explore if allowing patients to select the route of immunotherapy, educational sessions and strict follow-up could improve treatment compliance. Patients consulting allergy service were divided into two groups; if they chose the route of administration of immunotherapy, they were selected for the active group; if their physician decided, they were selected for the control group. All patients had to attend the allergy service monthly for control. Before the first application of immunotherapy, all patients received an educative session about the benefits and risks of the treatment. Patients in the active group received an additional session about subcutaneous and sublingual routes and they chose the most appropriate according to their personal characteristics. A total of 204 patients were in the active group and 103 were included in the control group. At six months, a total of 46 patients withdrew from immunotherapy during follow-up, 24 (11%) in the active group and 22 (21%) in the control group (p=0.02). In the active group we observed no statistically significant difference in adherence between those who preferred subcutaneous or sublingual immunotherapy; however in the control group, the drop out of sublingual immunotherapy was significantly higher than those who received subcutaneous (p=0.05). Educational sessions, strict follow-up and considering personal preferences of patients could improve adherence to allergen immunotherapy. Copyright © 2014 SEICAP. Published by Elsevier Espana.

    Methanogenic treatment of municipal solid waste (MSW) incineration leachate can be hindered by high concentrations of refractory organic matter and humification of compounds in the leachate. In an attempt to overcome some of these impediments, microbial electrolysis cells (MECs) were incorporated into anaerobic digesters (ADMECs). COD removal efficiencies and methane production were 8.7% and 44.3% higher in ADMECs than in controls, and ADMEC reactors recovered more readily from souring caused by high organic loading rates. The degradation rate of large macromolecules was substantially higher (96% vs 81%) in ADMEC than control effluent, suggesting that MECs stimulated degradation of refractory organic matter and reduced humification. Exoelectrogenic bacteria and microorganisms known to form syntrophic partnerships were enriched in ADMECs. These results show that ADMECs were more effective at treatment of MSW incineration leachate, and should be taken into consideration when designing future treatment facilities.

    Does repeat administration of misoprostol for early pregnancy loss increase the treatment success rate? Repeat administration of misoprostol does not increase the treatment success rate, and is associated with more analgesics use. Misoprostol reduces the need for surgical evacuation and shortens the time to complete expulsion in patients with early pregnancy loss. However, the impact of repeat doses of misoprostol is not clear. A randomized clinical trial was conducted in a single tertiary hospital, recruiting women with early pregnancy loss (misoprostol vaginally on Day 1, and were then randomly assigned into two groups: Patients in the single-dose group were evaluated on Day 8. Patients in the repeat-dose group were evaluated on Day 4, when they were given a repeat dose if required, and scheduled for re-evaluation on Day 8. If complete expulsion was not achieved on Day 8 (endometrial thickness >15 mm or the presence of gestational sac on transvaginal sonography), participants underwent surgical evacuation. The primary outcome was treatment success, defined as no need for surgical intervention up to Day 8. Final analysis included 87 participants in the single-dose group and 84 participants in the repeat-dose group, out of whom 41 (48.8%) received a second dose. Treatment succeeded in 67 (77%) patients in the single-dose group and 64 (76%) patients in the repeat-dose group (RR 0.98; 95% CI 0.83-1.16; P = 0.89). Patients in the repeat-dose group reported more use of over the counter analgesics (82.1% versus 69.0%, P = 0.04). The study was not blinded and our definition of complete expulsion may be debated. Follow-up time was not equal in all participants, since some had a complete expulsion on Day 4 and some underwent emergent D&C before Day 8. This, however, should not affect the primary outcome. Our results suggest that a single-dose protocol is superior to a repeat-dose protocol due to a comparable success rate and more favorable outcomes regarding the need for

    Uveal melanoma is a rare tumour with no established treatments once metastases develop. Although a variety of immune-based therapies have shown efficacy in metastatic cutaneous melanoma, their use in ocular variants has been disappointing. Recently, adoptive T-cell therapy has shown salvage responses in multiple refractory solid tumours. Thus, we sought to determine if adoptive transfer of autologous tumour-infiltrating lymphocytes (TILs) could mediate regression of metastatic uveal melanoma. In this ongoing single-centre, two-stage, phase 2, single-arm trial, patients (aged ≥16 years) with histologically confirmed metastatic ocular melanoma were enrolled. Key eligibility criteria were an Eastern Cooperative Oncology Group performance status of 0 or 1, progressive metastatic disease, and adequate haematological, renal, and hepatic function. Metastasectomies were done to procure tumour tissue to generate autologous TIL cultures, which then underwent large scale ex-vivo expansion. Patients were treated with lymphodepleting conditioning chemotherapy (intravenous cyclophosphamide [60 mg/kg] daily for 2 days followed by fludarabine [25 mg/m 2 ] daily for 5 days, followed by a single intravenous infusion of autologous TILs and high-dose interleukin-2 [720 000 IU/kg] every 8 h). The primary endpoint was objective tumour response in evaluable patients per protocol using Response to Evaluation Criteria in Solid Tumors, version 1.0. An interim analysis of this trial is reported here. The trial is registered at ClinicalTrials.gov, number NCT01814046. From the completed first stage and ongoing expansion stage of this trial, a total of 21 consecutive patients with metastatic uveal melanoma were enrolled between June 7, 2013, and Sept 9, 2016, and received TIL therapy. Seven (35%, 95% CI 16-59) of 20 evaluable patients had objective tumour regression. Among the responders, six patients achieved a partial response, two of which are ongoing and have not reached maximum

    To evaluate potential risk factors at admission for failed single-dose methotrexate injection in women with ectopic pregnancy. File review of a tertiary medical center in Israel yielded 102 consecutive patients with ectopic pregnancy initially treated with single-dose methotrexate. Overall successful treatment was defined as normalization of human chorionic gonadotropin (hCG) levels after the first or second injection. The mean pretreatment hCG level for the whole cohort was 2350 ± 2955 mIU/mL (median, 1187 mIU/mL; 90th percentile, 5000 mIU/mL). Resolution of ectopic pregnancy was achieved after a single injection in 76/102 (74.5%) women and after a second dose in 16/21 (76.2%) women. The remaining 10 (9.8%) patients were treated surgically after the first (5/76) or the second (5/26) dose. The overall success rate for methotrexate treatment was 90.2%. On multivariate stepwise logistic analysis, fetal cardiac activity was an independent predictor of a failed first methotrexate injection, and presence of a yolk sac and mass size were independent predictors of overall methotrexate failure and need for secondary surgery. In patients with ectopic pregnancy and relatively low levels of serum hCG, the most important predictors of overall failure of methotrexate injection were the presence of a yolk sac and mass size.

    A single-step most-probable-number method for determining the number of fecal coliform bacteria present in sewage treatment plant effluents is discussed. A single growth medium based on that of Reasoner et al. (1976) and consisting of 5.0 gr. proteose peptone, 3.0 gr. yeast extract, 10.0 gr. lactose, 7.5 gr. NaCl, 0.2 gr. sodium lauryl sulfate, and 0.1 gr. sodium desoxycholate per liter is used. The pH is adjusted to 6.5, and samples are incubated at 44.5 deg C. Bacterial growth is detected either by measuring the increase with time in the electrical impedance ratio between the innoculated sample vial and an uninnoculated reference vial or by visual examination for turbidity. Results obtained by the single-step method for chlorinated and unchlorinated effluent samples are in excellent agreement with those obtained by the standard method. It is suggested that in automated treatment plants impedance ratio data could be automatically matched by computer programs with the appropriate dilution factors and most probable number tables already in the computer memory, with the corresponding result displayed as fecal coliforms per 100 ml of effluent.

    Single-stage management of CBD stones comprises simultaneous common bile duct (CBD) clearance and cholecystectomy. The CBD can be cleared by using endoscopic treatment (ET) or laparoscopic surgery (LS) alone. To determine the most rapid recovery after the single-stage laparoscopic management of CBD stones. Patients with CBD stones treated at either of two centers (one performing ET only and one performing LS only for single-stage treatment) were included. The primary endpoint was "the textbook outcome". The feasibility rate was 74% for ET and 100% for LS (p≤0.001). The proportion of cases with the textbook outcome was higher in the ET group than in the LS-only group (73% vs. 10%; pCBD clearance rate was similar in the ET and LS-only groups (100% vs. 96.6%, respectively; p=0.17). The overall morbidity rate was lower in the ET group than in the LS-only group (23% vs. 29%, p=0.05). Both ET and LS are feasible, safe and effective for clearance of the CBD. ET was better than LS in terms of a less frequent requirement for drainage and a shorter length of hospital stay. LS was associated with a shorter operating time.

    Multiple clinical practice guidelines recommend rapid evaluation of patients with suspected lung cancer. It is uncertain whether delays in diagnosis and management have a negative effect on outcomes. This retrospective study included 551 patients diagnosed with lung cancer through the diagnostic assessment program at the Institut universitaire de cardiologie et de pneumologie de Québec between September 2013 and March 2015. Median wait times between initial referral, diagnosis, and first treatment were calculated and compared with recommended targets. Analyses were performed to evaluate for specific factors associated with longer wait times and for the effect of delays on the outcomes of progression-free survival (pfs), relapse-free survival (rfs) after primary surgical resection, and overall survival (os). Most patients were investigated and treated within recommended targets. Of the entire cohort, 379 patients were treated at our institution. Of those 379 patients, 311 (82%) were treated within recommended targets. In comparing patients within and outside target times, the only statistically significant difference was found in the distribution of treatment modalities: patients meeting targets were more likely to be treated with surgery or chemotherapy rather than with radiation. The pfs on first treatment modality was influenced by clinical stage, but not by time to therapy [hazard ratio (hr): 1.10; p = 0.65]. The os for the entire cohort was also influenced by stage, but not by delays (hr: 1.04; p = 0.87). For the 209 patients treated by surgery with curative intent, a significant reduction in rfs was associated with male sex and TNM stage, but not with delays (hr: 1.11; p = 0.83). The os after primary surgical resection was also associated with TNM stage, but not with delays (hr: 1.82; p = 0.43). Recommended targets for wait times in the investigation and treatment of lung cancer can be achieved within a diagnostic assessment program. Compared with radiation

    The authors report the observation of a 43-year-old woman with severe pain on her right upper abdominal quadrant. Differential diagnoses included acute cholecystitis, spontaneous pneumothorax, perforated appendicitis and a recidive of renal calculus. CT-scan showed a huge subdermal gas bubble along her right flank and anterior abdominal wall up to the submammary fold. Only at this point, the patient admitted to have undergone a carboxytherapy procedure on both thighs one day before onset of pain in a paramedical facility. As some of the injection trajects were still patent on CT-scan, she received prophylactic antibiotic coverage. Though there was a complete resorption of gas after 10 days, dysesthesias and muscle contracture persisted for 3 weeks. To the authors' knowledge this migration and coalescence of injected gas in a single bubble has not been previously reported.

    Excessive maternal weight gain during pregnancy impacts on offspring health. This study focused on the timing of maternal gestational weight gain, using a porcine model with mothers of normal pre-pregnancy weight. Trial design ensured the trajectory of maternal gestational weight gain differed across treatments in early, mid and late gestation. Diet composition did not differ. On day 25 gestation, sows were assigned to one of five treatments: Control sows received a standard gestation diet of 2.3 kg/day (30 MJ DE/day) from early to late gestation (day 25-110 gestation). E sows received 4.6 kg food/day in early gestation (day 25-50 gestation). M sows doubled their food intake in mid gestation (day 50-80 gestation). EM sows doubled their food intake during both early and mid gestation (day 25-80 gestation). L sows consumed 3.5 kg food/day in late gestation (day 80-110 gestation). Offspring body weight and food intake levels were measured from birth to adolescence. Markers of lipid metabolism, hypertrophy and inflammation were investigated in subcutaneous adipose tissue of adolescent offspring. The trajectory of gestational weight gain differed across treatments. However total gestational weight gain did not differ except for EM sows who were the heaviest and fattest mothers at parturition. Offspring birth weight did not differ across treatments. Subcutaneous adipose tissue from EM offspring differed significantly from controls, with elevated mRNA levels of lipogenic (CD36, ACACB and LPL), nutrient transporters (FABP4 and GLUT4), lipolysis (HSL and ATGL), adipocyte size (MEST) and inflammation (PAI-1) indicators. The subcutaneous adipose depot from L offspring exhibited elevated levels of CD36, ACACB, LPL, GLUT4 and FABP4 mRNA transcripts compared to control offspring. Increasing gestational weight gain in early gestation had the greatest impact on offspring postnatal growth rate. Increasing maternal food allowance in late gestation appeared to shift the offspring

    Full Text Available Third molar surgery is one of the most frequently performed procedures in oral and maxillofacial surgery. Various complications including pain, bleeding, infection, edema, hematoma, perforation of the maxillary sinus, and subcutaneous emphysema (SE can occur after third molar surgery. Cervicofacial subcutaneous emphysema (CSE most often occurs after the extraction of third molars, especially when using high-speed air-turbine drills and air syringes, or during dental laser treatment or even after endodontic treatment. This report presents the diagnosis and treatment protocol of a CSE in a 42-year-old healthy male patient that occurred after extraction of a totally erupted upper third molar with just a straight elevator and extraction forceps.

    In this research, we have studied the consequences of three consecutive osteopathic manipulative sessions (OMS) on postural control by using a single-case research (SCR) design. The patient was a 77 years old woman complaining of altered balance and low-back pain. OMS were delivered by a single practitioner. The pain level was self-rated by using a visual Borg scale. The posture was monitored on a force platform. Postural parameters were deduced from the analysis of the centre of foot pressure (CoP) displacement. The statistical significance of the observed differences was established by using an SCR-related effect size indicator (i.e. Taunovlap). Our results indicate that OMS decrease the patient's pain, modify CoP mean position and decreased the length and velocity of the CoP displacement. Furthermore, modifications of the body oscillations were observed after OMS. This work indicates that OMS can improve body balance and that SCR allows the objective evaluation of the consequences of OMS. Copyright © 2014 Elsevier Ltd. All rights reserved.

  17. The Success of the Single-Dose Methotrexate Treatment in an Atypical Heterotopic Pregnancy

    2016-06-01

    Full Text Available Heterotopic pregnancy refers to simultaneous presence of intrauterine and ectopic gestational sacs. Its incidence ex­hibits a rising trend due to the increased use of assisted reproductive technology (ART. This paper aims to present a rare case of tubal and cesarean scar heterotopic pregnancy that occurred following a spontaneous pregnancy. The pa­tient presenting with delayed menstruation and abdominal-inguinal pain was evaluated. Transvaginal ultrasonography revealed a gestational sac located in the scar of a previous cesarean section and in the left tubal region corresponding to a gestational age of 4 weeks and 5 days. The patient was hospitalized and informed about conservative and surgi­cal methods. Then, she was administered a single dose of methotrexate 75 mg intramuscularly. Post-operative period included ultrasonographic and laboratory follow-up. In conclusion, it should be remembered that single-dose systemic methotrexate therapy might constitute an alternative to surgery in unruptured hemodynamically stable cases.

  18. Reinfection of dogs with fish-borne zoonotic trematodes in northern Vietnam following a single treatment with praziquantel.

    Directory of Open Access Journals (Sweden)

    Sofie Nissen

    Full Text Available BACKGROUND: Fish-borne zoonotic trematodes (FZT infections including liver- and minute intestinal flukes are common in Southeast Asia in both humans and domestic animals eating raw fish and since 2010, the liver flukes are recognised as neglected tropical diseases by WHO. Mass drug treatment with praziquantel is advised for humans, but no recommendations for control of the FZT in the reservoir hosts exist. METHODOLOGY/PRINCIPAL FINDINGS: A study was conducted to assess the ability of praziquantel treatment for control of FZT in farm dogs in an endemic area in Northern Vietnam. Initially, 101 dogs from 73 households were examined for small trematode eggs in their faeces. Forty seven copro-positive dogs were included in the study. Thirty eight dogs received treatment with a single dose of 40 mg/kg of praziquantel. A group of nine dogs were left untreated. Coprological examination for small trematode eggs was performed on day 0, 3, 10, 30, 60, 90 and 120 post treatment. Farmers were questioned about dog keeping practises. All dogs were copro-negative for small trematode eggs on both day 3 and 10 post treatment. From day 30 onwards previously negative dogs became positive again. The reinfection rates were 26.3% (day 30, 45.5% (day 60, 53.1% (day 90, 61.3% (day 120.The nine untreated dogs remained positive throughout the study period. There was no difference in the intensity of infection at day 0 and 120 neither in the treated or untreated group. CONCLUSION: Dogs had easy access to raw fish and did not receive treatment against flukes by their owner. More than 50% of the dogs were reinfected 3 months post treatment. We do not recommend controlling FZT infections in dogs by anthelmintic treatment alone since reinfection occurs fast under the existing farm management systems.

    Effect of microwave radiation (24 GHz) on transformation of impurity-defect complexes in CdTe:Cl single crystals within the spectral range 1.3–1.5 eV was studied using the low-temperature (T=2 K) photoluminescence (PL) technique. The shapes of donor–acceptor pairs (DAP) and Y PL bands were studied in detail. The Huang–Rhys factor was calculated for the DAP luminescence depending on microwave radiation treatment. The increase of the distance between the DAP components responsible for emission at 1.455 eV and the quenching of Y-band due to microwave irradiation were observed. The method to decrease the amount of extended defects in near-surface layers of CdTe:Cl single crystals has been proposed.

    To describe the safety and efficacy of pegvisomant therapy and the predictors of treatment response in acromegaly patients at a single tertiary reference center in Brazil. We retrospectively reviewed the clinical, hormonal and radiological data of acromegaly patients treated with pegvisomant in our center. We also evaluated the presence of the d3 isoform of the growth hormone receptor (d3GHR). Twenty-seven patients were included (17 women). Pegvisomant was used in combination with octreotide LAR in 20 patients (74%), in combination with cabergoline in one (4%) and as monotherapy in six (22%). IGF-I normalization was achieved in 23 patients (85%). Mild and transitory elevation of liver enzymes was observed in two patients (7.4%), tumor growth in one (3.4%) and lipodystrophy in two (7.4%). One patient stopped the drug due to headaches. The GHR isoforms were evaluated in 14 patients, and the presence of at least one d3GHR allele was observed in 43% of them, but it was not a predictor of treatment response. Only pre-treatment IGF-I level was a predictor of treatment response. Pegvisomant treatment was highly effective and safe in our series of Brazilian patients. A better chance of disease control can be expected in those with lower pre-pegvisomant IGF-I levels.

    To investigate the effects of salpingectomy and methotrexate treatments on ovarian reserve in ectopic pregnancy. In this prospective study, a total of 131 patients with ectopic pregnancy were divided into 3 groups of methotrexate (MTX) only (Group-1, n: 55), salpingectomy only (Group-2, n: 61), and salpingectomy following MTX (Group-3, n: 15). Pretreatment and post-treatment anti-Müllerian hormone (AMH) levels were evaluated. Significant differences in AMH levels were detected between group 1 and group 2 (2.52±1.28 vs. 1.96±1.66, p=0.043), and group 1 and group 3 (2.52±1.28 vs. 1.77±0.76, p=0.035) at one month postoperative. However, these differences disappeared at the 3rd postoperative month. When AMH levels were compared within the same group, postoperative one month AMH levels were significantly lower than the preoperative AMH levels only in group 3 (p=0.03). However, this difference also disappeared at the 3rd postoperative month. Systemic single-dose methotrexate treatment, unilateral salpingectomy, and salpingectomy following methotrexate administration in ectopic pregnancy were reassuring based on pretreatment and post-treatment AMH levels. Current medical and surgical treatment approaches do not have an obvious negative effect on ovarian reserve. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  3. Long term mortality after a single treatment course with X-rays in patients treated for ankylosing spondylitis

    Mortality up to 1 January 1983 has been studied in 14,106 patients with ankylosing spondylitis given a single course of X-ray treatment during 1935-54. For neoplasms other than leukaemia or colon cancer, mortality was 28% greater than that of members of the general population of England and Wales, and this increase is likely to have been a direct consequence of the treatment. The proportional increase reached a maximum of 71% between 10.0 and 12.4 years after irradiation and then declined. There were only a 7% increase in mortality from these tumours more than 25.0 years after irradiation and only for cancer of the oesophagus was the relative risk significantly raised in this period. Neither the magnitude of the relative risk, nor its temporal pattern following treatment, were greatly influenced by the age of the patient at first treatment. For leukaemia there was a threefold increase in mortality that is also likely to have been due to the radiotherapy. For colon cancer mortality was increased by 30%. For non-neoplastic conditions there was a 51% increase in mortality that was likely to be associated with the disease itself rather than its treatment. (author)

    Stereotactic radiosurgery/radiotherapy procedures are known to deliver a very high dose per fraction, and thus, the corresponding peripheral dose could be a limiting factor for the long term surviving patients. The aim of this clinical study was to measure the peripheral dose delivered to patients undergoing intracranial Cyberknife treatment, using the MOSFET dosimeters. The influence of the supplemental shielding, the number of monitor units and the collimator size to the peripheral dose were investigated. MOSFET dosimeters were placed in preselected anatomical regions of the patient undergoing Cyberknife treatment, namely the thyroid gland, the nipple, the umbilicus and the pubic symphysis. The mean peripheral doses before the supplemental shielding was added to the Cyberknife unit were 51.79 cGy, 13.31 cGy and 10.07 cGy while after the shielding upgrade they were 38.40 cGy, 10.94 cGy, and 8.69 cGy, in the thyroid gland, the umbilicus and the pubic symphysis, respectively. The increase of the collimator size corresponds to an increase of the PD and becomes less significant at larger distances, indicating that at these distances the PD is predominate due to the head leakage and collimator scatter. Weighting the effect of the number of monitor units and the collimator size can be effectively used during the optimization procedure in order to choose the most suitable treatment plan that will deliver the maximum dose to the tumor, while being compatible with the dose constraints for the surrounding organs at risk. Attention is required in defining the thyroid gland as a structure of avoidance in the treatment plan especially in patients with benign diseases

    Refractory epilepsies in children present a major burden for patients and their families. Cannabidiol (CBD) has been suggested as a potential treatment for refractory epilepsies. The aim of this study was to evaluate the effectiveness of add-on therapy with CBD for the treatment of refractory childhood epilepsies. Patients with childhood-onset refractory epilepsy, treated at the tertiary epilepsy center of the University Children's Hospital Ljubljana, Slovenia, were included in the study. Add-on therapy with CBD was initiated once the child's epilepsy was categorized as pharmacoresistant to other antiepileptic drugs/therapies. The dosage of CBD was gradually increased to at least 8mg/kg/day. The effect of CBD treatment was evaluated by the reduction in seizure burden and presence of side effects (positive and negative). Serial electroencephalography was performed in some children. Sixty-six patients were included in the analysis. Thirty-two (48.5%) patients had a more than 50% improvement regarding seizure burden, 14 of whom (21.2%) became seizure-free. None of the patients reported worsening of seizure frequency, but CBD had no effect in 15 (22.7%) patients. Some patients reported less vigorous seizures, shorter duration of seizures, shorter time to recovery, and other positive side effects of CBD treatment. Adverse effects were reported in 5/66 children. In our cohort of patients, CBD was found to have potential benefits as add-on therapy for refractory childhood epilepsies, mainly by reducing seizure burden. Copyright © 2018 Elsevier Inc.

    Endoscopic mucosal resection (EMR) has emerged for evaluation and treatment of esophageal nodules. We report our initial experience with EMR for T staging and management of early esophageal cancer. We reviewed patients undergoing EMR for esophageal adenocarcinoma between 2008 and 2013. The primary outcome measure was needed for esophagectomy. Secondary outcomes included complete eradication of adenocarcinoma, recurrence or persistence of cancer, nodal status for those undergoing esophagectomy, and complications of endoscopic treatment. During the study period, 24 patients underwent EMR demonstrating carcinoma, and a grossly margin negative endoscopic resection was achieved in all cases. Ten patients (42 %) had evidence of submucosal invasion and were referred for esophagectomy. Patients with margin negative EMR (n = 10, 42 %) or positive radial margins (n = 4, 16 %) underwent endoscopic surveillance and treatment with radiofrequency ablation or repeat EMR as needed. Thirteen patients (93 %) with intramucosal cancer (IMC) have been successfully managed with ongoing endoscopic surveillance and treatment with a median follow-up of 15.5 months. One patient underwent esophagectomy due to recurrent IMC in the setting of long-segment multifocal high-grade dysplasia. There were no esophageal perforations, one patient developed a self-limited gastrointestinal hemorrhage following EMR, and one had an esophageal stricture following endoscopic management. IMC can be successfully managed endoscopically and thus esophagectomy is avoided in a significant proportion of patients. Endoscopic management may be utilized in the setting of complete resection or radial margin involvement without evidence of submucosal invasion. Close endoscopic follow-up is of paramount importance even in those with negative margins, because recurrent disease may occur following EMR in these patients.

    With improved survival of childhood cancer patients, the number of long-term cancer survivors is increasing. Some studies have assessed the long-term morbidity after childhood cancer treatment in the developing countries. This study was conducted to assess the spectrum of late effects of cancer treatment in paediatric cancer survivors. Evaluation of the first 300 patients who completed five years of follow up in the after treatment completion clinic was done. Details of primary diagnosis, treatment received and current clinical status were noted. The spectrum of late effects was ascertained by appropriate investigations. Haematological malignancies comprised 25 per cent of total cases. Most common primary diagnosis comprised acute lymphoblastic leukaemia, retinoblastoma and Hodgkin's lymphoma. The median age at evaluation and follow up was 14 and 8.5 yr, respectively. Twenty three per cent (69) of the survivors had a minimal disability (growth retardation or underweight), 13 per cent (39) had moderate disabilities needing medical attention (hepatitis B surface antigen positive, myocardial dysfunction, azoospermia and hypothyroidism), while two per cent had major/life-threatening disabilities (mental retardation, liver disease and mortality). Eleven patients relapsed on follow up, of those five patients expired. Two second malignancies were recorded during the period of follow up. Late effects were of concern; however, severe disability (Grade 3-5) was seen in only two per cent survivors. Lifelong follow up of childhood cancer survivors is required to assess cancer-related morbidity, occurrence of a secondary neoplasm, to facilitate timely diagnosis and to implement remedial or preventive interventions to optimize health outcomes. Awareness towards the existence of late effects of cancer therapy is required among parents, patients and health professionals.

    Endoscopic Interventional Treatment is of little trauma and less complications in the treatment of gastric schwannoma and leads to faster recovery and fewer days of hospitalization. This study was aimed to investigate the safety and efficacy of endoscopic interventional therapy for gastric schwannoma, including endoscopic submucosal excavation, non-laparoscopic-assisted endoscopic full-thickness resection, endoscopic tunneling submucosal resection, and so on. Six patients of gastric schwannoma diagnosed by pathology examination were retrospectively analyzed ranging from Oct 2011 to Feb 2014 at Shandong Provincial Hospital affiliated to Shandong University. Five of the six patients accepted endoscopic interventional therapy. Among the five patients, there were four males and one female, aged from 48 to 65 years old (the average age was 58 ± 6.4). The lesions located at the fundus, the fundus-cardia, gastric body or gastric antrum, respectively, with the diameters ranged from 8 to 25 millimeter (the average was 17.1 ± 7.8 mm). All the patients were performed endoscopic interventional therapy successfully. Among five patients, one patient was treated by endoscopic tunneling submucosal resection, two by endoscopic submucosal excavation, and the other two were given endoscopic full-thickness resection. Operation duration was about 43 to 83 minutes (the average was 57.6 ± 16.1 minutes). The mass were completely removed, with limited bleeding. During the operation, perforation and pneumoperitoneum occurred in two patients, who finally recovered by endoscopic and conservative treatment. No bleeding, inflammation or infection occurred in these patients. The average follow-up time was (7.4 ± 4.4) months. Neither recurrence nor metastasis was found during follow-up. Endoscopic interventional therapy is a safe and effective treatment for gastric schwannoma.

    Full Text Available Abstract Background Lung cancer is a malignant carcinoma which has the highest morbidity and mortality in Chinese population. Gefitinib, a tyrosine kinase (TK inhibitor of epidermal growth factor receptor (EGFR, displays anti-tumor activity. The present data regarding first-line treatment with single agent gefitinib against non-small-cell lung cancer (NSCLC in Chinese population are not sufficient. Purpose To assess the efficacy and toxicity of gefitinib in Chinese patients with advanced non-small-cell lung cancer (NSCLC, a study of single agent treatment with gefitinib in Chinese patients was conducted. Methods 45 patients with advanced NSCLC were treated with gefitinib (250 mg daily until the disease progression or intolerable toxicity. Results Among the 45 patients, 15 patients achieved partial response (PR, 17 patients experienced stable disease (SD, and 13 patients developed progression disease (PD. None of the patients achieved complete response (CR. The tumor response rate and disease control rate was 33% and 71.1%, respectively. Symptom remission rate was 72.5%, and median remission time was 8 days. Median overall survival and median progression-free survival was 15.3 months and 6.0 months, respectively. The main induced toxicities by gefitinib were skin rash and diarrhea (53.3% and 33.3%, respectively. The minor induced toxicities included dehydration and pruritus of skin (26.7% and 22.2%, respectively. In addition, hepatic toxicity and oral ulceration occurred in few patients (6.7% and 4.4%2, respectively. Conclusions Single agent treatment with gefitinib is effective and well tolerated in Chinese patients with advanced NSCLC.

    Renal cell carcinoma (RCC) is more common in renal transplant and dialysis patients than the general population. However, RCC in transplanted kidneys is rare, and treatment has previously consisted of nephrectomy with a return to dialysis. There has been recent interest in nephron-sparing procedures as a treatment option for RCC in allograft kidneys in an effort to retain allograft function. Four patients with RCC in allograft kidneys were treated with nephrectomy, partial nephrectomy, or radiofrequency ablation. All of the patients are without evidence of recurrence of RCC after treatment. We found nephron-sparing procedures to be reasonable initial options in managing incidental RCCs diagnosed in functioning allografts to maintain an improved quality of life and avoid immediate dialysis compared with radical nephrectomy of a functioning allograft. However, in non-functioning renal allografts, radical nephrectomy may allow for a higher chance of cure without the loss of transplant function. Consequently, radical nephrectomy should be utilized whenever the allograft is non-functioning and the patient's surgical risk is not prohibitive. © 2013 John Wiley & Sons A/S.

    Multiple sclerosis (MS) is a chronic inflammatory demyelinating and neurodegenerative disease of the central nervous system characterized by unpredictable and variable clinical course. Etiology of MS involves both genetic and environmental factors. New technologies identified genetic polymorphisms associated with MS susceptibility among which immunologically relevant genes are significantly overrepresented. Although individual genes contribute only a small part to MS susceptibility, they might be used as biomarkers, thus helping to identify accurate diagnosis, predict clinical disease course and response to therapy. This review focuses on recent progress in research on MS genetics with special emphasis on the possibility to use single nucleotide polymorphism of candidate genes as biomarkers of susceptibility to disease and response to therapy.

    Given the important functions of TP53 pathway in various biological processes, this study aimed to investigate the expression of TP53 pathway-related proteins in ovarian carcinoma transplanted subcutaneously in nude mice with and without the presence of p53 inhibitor and to explore possible roles of p53 in the development of ovarian cancer. Thirty BALB/c-nu female nude mice were randomly divided into model group, control group and p53 inhibitor group (Pftα group). There were 10 rats in each group. The nude mice were subcutaneously inoculated with human ovarian cancer cell line SKOV3, and the tumor growth was observed. Morphological changes of tumor tissue were observed by hematoxylin and eosin (HE) staining. The mRNA and protein levels of TP53 pathway related factors-p53, p21 and mouse double minute 2 homolog (MDM2) were detected by RT-PCR and Western blot. p53 inhibitor can increase the growth rate of subcutaneously transplanted tumor in nude mice. p53 inhibitor could decrease the expression of p53 and p21 at both mRNA and protein levels and increase the expression of MDM2 at both mRNA and protein levels in ovarian carcinoma transplanted subcutaneously in nude mice. TP53 pathway may play pivotal roles in the development of ovarian cancer and TP53 pathway may be a new target for the treatment of ovarian cancer.

    To find the frequency of deformity correction, functional outcome and complications of single-stage vertebral column resection in patients with kyphotic deformity. The prospective case series was conducted at Hayatabad Medical Complex, Peshawar, and Aman Hospital, Peshawar, from January 2012 to December 2013, and comprised all patients who underwent single-stage posterior vertebral column resection. Only patients with severe rigid sharp deformity of different aetiology that required more than 40 degree correction and who had at least 3-month follow-up were included. Data was processed using SPSS 16. Of the total 18 patients, 11(61.1%) were male and 7(38.9%) were female, with an overall mean age of 28.7±13.6 years (range: 12-60 years). Among them, 8(44.4%) patients had congenital kyphosis, 5(27.8%) had posttraumatic origin, 4(22.2%) had post-tuberculous deformity, while 1(5.6%) had iatrogenic kyphosis. The apex of the deformity was in thoracic spine in 12(66.7%) patients, while in 6(33.3%) patients it was in the lumbar spine. The average pre- and post-operative Cobb's angle was 66.2±18.9 degrees and 18.8±12.8 degrees respectively. Mean correction of deformities was 47.3±13.3 degrees. The mean correction achieved in percentage terms was 73.5±8.6 per cent (range: 56-87%). There were no patients with post-operative deterioration of neurological status. Two (11%) patients underwent re-exploration of the wounds with wash and cultures due to wound discharge. Posterior vertebral column resection was found to be a very effective method of correction of severe kyphotic deformities in expert hands with acceptable morbidity.

    The incidence of vulvar cancer is increasing, but surgical treatment-the current standard of care-often leads to unsatisfactory outcomes, especially in patients with node-positive disease. Preliminary results at our centre showed that locoregional spread of vulvar carcinoma occurs within tissue domains defined by stepwise embryonic and fetal development (ontogenetic cancer fields and associated lymph node regions). We propose that clinical translation of these insights into practice could improve outcomes of surgical treatment of vulvar cancer. We did a single-centre prospective trial at the University of Leipzig's Cancer Center. Eligible patients were aged 18 years or older, had ontogenetic stage 1-3b histologically proven primary carcinoma of the vulva, and had not undergone previous surgical or radiotherapy treatment for vulvar cancer or any other major perineal or pelvic disease. In view of staged morphogenesis of the vulva from the cloacal membrane endoderm at Carnegie stage 11 to adulthood, we defined the tissue domains of tumour spread according to the theory of ontogenetic cancer fields. On the basis of ontogenetic staging, patients were treated locally with partial, total, or extended vulvar field resection; regionally with therapeutic inguinopelvic lymph node dissection; and anatomical reconstruction without adjuvant radiotherapy. The primary endpoints were recurrence-free survival, disease-specific survival, and early postoperative complications. Analysis of tumour spread and early postoperative surgical complications was done by intention to treat (ie, all patients were included), whereas outcome analyses were done per protocol. This ongoing trial is registered with the German Clinical Trials Register, number DRKS00013358. Between March 1, 2009, and June 8, 2017, 97 consecutive patients were included in the study, of whom 94 were treated per protocol with vulvar field resection, therapeutic inguinopelvic lymph node dissection, and anatomical

    Low fat composition in newborns exposes them to an immediate risk of increased mortality and morbidity, inhibited physical and cognitive development and to diabetes and obesity diseases in later life. Information about nutritional and dietary status of newborns can be accessed by measuring the amount of fat composition in the body. The functions of subcutaneous fat involve energy storage, thermo-insulation and a physical buffer. Current technologies for newborn body fat monitoring are: a device based on air displacement plethesmography (PeaPod), dual-energy Xray, and underwater weighting. However they are bulky, expensive, immobile, and require technical expertise. We propose an alternative portable measurement system of in-vitro for subcutaneous fat that uses diffuse near-infrared light reflectance measurement system. We also introduce an in-vitro three-layered tissue model mimicking the subcutaneous fat layer in newborns together with a preliminary study to measure fat using dual-wavelength nearinfrared light. Based on the output data from these measurements, we have proposed a suitable transmission and scattering model. This model estimated the amount of reflected light collected by a photodetector after incident light is scattered in several fat layers. Our portable sensor is low cost and does not require training hence it is suitable for mass use in the developing world. It consists of a single LED and two photodetectors (900 nm and 1000 nm). The photodetectors wavelengths were chosen to be sensitive to fat as it exhibits a peak in the wavelength at 930 nm and to water at which exhibits a peak at 980 nm; the latter is used, to remove hydration bias. Results on a porcine tissue model demonstrate differentiation as low as 2 mm fat which is a relevant screening thickness to indicate low percentage body fat.

    Full Text Available Objective: To study the effect of continuous subcutaneous insulin pump infusion on glucolipid metabolism as well as inflammation and oxidative stress in placenta of patients with gestational diabetes mellitus (GDM. Methods: Patients with GDM who received insulin therapy between March 2013 and May 2016 were selected as the research subjects and randomly divided into multiple subcutaneous insulin injection (MSII group and continuous subcutaneous insulin pump infusion (CSII group. Before and after treatment, serum glucolipid metabolism as well as inflammation and oxidative stress inexes in placenta were determined respectively. Results: 2 weeks and 4 weeks after treatment, FBG, 1hPBG, 2hPBG, Chemerin, Vaspin and Visfatin levels of both groups of patients were significantly lower than those before treatment and FBG, 1hPBG, 2hPBG, Chemerin, Vaspin and Visfatin levels of CSII group were significantly lower than those of MSII group; after delivery, TNF-α, IL-6, ROS and AGEs levels in placenta of CSII group were significantly lower than those of MSII group. Conclusion: Continuous subcutaneous insulin infusion can more effectively improve the glucolipid metabolism and inhibit the inflammation and oxidative stress in placenta of patients with GDM than multiple subcutaneous insulin injection.

    One of the underestimated causes of chronic pelvic pain (CPP) in women may be pelvic congestion syndrome (PCS) that is defined as the presence of varicose of ovarian and pelvic veins associated with chronic pain in the region of the pelvis. This pain is present longer than 6 months and intensifies with prolonged standing, coitus and menstruation. The disease constitutes a diagnostic as well as therapeutic problem, thus posing a challenge for the clinician. Transcatheter ovarian vein embolization might be a safe and effective option for PCS treatment. The objective of this study was to evaluate the efficacy of ovarian vein embolization ovarian as a method of the PCS treatment. Between 2002-2012, 11 embolization procedures were performed in 10 women (age range: 34-43; median age 39) with the diagnosis of PCS. One patient underwent embolization procedure twice. In 1 case the combined therapy of endovascular embolization and surgical phlebectomy of vulvar varices was performed. There were no major intrainterventional complications. In all the patients (100%) a significant improvement in the clinical status was noted. The procedure improved the quality of life in the patients. Three women (30%) had a mild recurrence of the symptoms at mid-term follow-up. Among 8 women who had complained of dyspareunia prior to embolization 6 patients reported complete pain relief, in other 2 cases the pain subsided partially. There was a significant decrease in the severity of symptoms associated with hemorrhoids. We consider embolization of insufficient ovarian veins an effective and safe way of treatment in a well-selected group of patients with PCS.

    The present study examined the effect of natural antimicrobials: chitosan, oregano and their combination, on the shelf-life of modified atmosphere packaged chicken breast meat stored at 4°C. Treatments examined in the present study were the following: M (control samples stored under modified atmosphere packaging), M-O (samples treated with oregano oil 0.25% v/w, stored under MAP), M-CH (samples treated with chitosan 1.5% w/v, stored under MAP) and M-CH-O (treated with chitosan 1.5% w/v and oregano oil 0.25% v/w, stored under MAP). Treatment, M-CH-O, significantly affected mesophilic Total Plate Counts (TPC), lactic acid bacteria (LAB), Brochothrix thermosphacta, Enterobacteriaceae, Pseudomonas spp., and yeasts-moulds during the storage period. Lipid oxidation (as determined by MDA values) of control and treated chicken samples was in general low and below 0.5 mg MDA/kg, showing no oxidative rancidity during the storage period. Addition of chitosan to the chicken samples produced higher (P15 (M-CH and M-CH-O) days. Interestingly, chitosan (M-CH) or chitosan-oregano (M-CH-O) treated chicken samples were sensorially acceptable during the entire refrigerated storage period of 21 days. It is noteworthy that the presence of chitosan in M-CH and M-CH-O samples did not negatively influence the taste of chicken samples, with M-CH samples receiving a higher score (compared to M-CH-O), probably as a result of a distinct and "spicy" lemon taste of chitosan, that was well received by the panelists. Based primarily on sensory data (taste attribute) M-CH and M-O treatments extended the shelf-life of chicken fillets by 6 days, while M-CH-O treatment resulted in a product with a shelf-life of 14 days, maintaining acceptable sensory characteristics.

    Low lumbar osteoporotic vertebral collapse (OVC) has not been well documented compared with OVC of the thoracolumbar spine. The differences between low lumbar and thoracolumbar lesions should be studied to provide better treatment. The aim of this study was to clarify the clinical and imaging features as well as outcomes of low lumbar OVC and to discuss the appropriate surgical treatment. Thirty patients (10 men; 20 women; mean age 79.3 ± 4.7 years [range 70-88 years]) with low lumbar OVC affecting levels below L-3 underwent surgical treatment. The clinical symptoms, morphological features of affected vertebra, sagittal spinopelvic alignment, neurological status before and after surgery, and surgical procedures were reviewed at a mean follow-up period of 2.4 years. The main clinical symptom was radicular leg pain. Most patients had old compression fractures at the thoracolumbar level. The affected vertebra was flat-type and concave or H-shaped type, not wedge type as often found in thoracolumbar OVC. There were mismatches between pelvic incidence and lumbar lordosis on plain radiographs. On CT and MR images, foraminal stenosis was seen in 18 patients (60%) and canal stenosis in 24 patients (80%). Decompression with short fusion using a posterior approach was performed. Augmentations of vertebroplasty, posterolateral fusion, and posterior lumbar interbody fusion were performed based on the presence/absence of local kyphosis of lumbar spine, cleft formation, and/or intervertebral instability. Although the neurological and visual analog scale scores improved postoperatively, 8 patients (26.7%) developed postoperative complications mainly related to instrumentation failure. In patients with postoperative complications, lumbar spine bone mineral density was significantly low, but the spinopelvic alignment showed no correlation when compared with those without complications. The main types of low lumbar OVC were flat-type and concave type, which resulted in neurological

RESULTS: A total of 73 consecutive patients with mCRPC undergoing treatment with AA between November 2012 and October 2014 were included. Median follow-up was 9.9 (0.9-23.4) months. PSA decline>50% was found in 39...... trial. Except for PSA response (>50% decline) in patients managed with AA, postchemotherapy results were inferior to phase III studies. This is most likely because of patient selection, which is a typical weakness when transferring results from phase III trials into clinical practice....
