    In this study, we compared the changes in arterial stiffness in chronic hemodialysis patients treated with 8-h vs. 4-h thrice weekly in-center hemodialysis. Sixty prevalent chronic hemodialysis patients assigned to 8-h nocturnal in-center thrice weekly HD (NHD) and 60 control cases assigned to 4-h thrice weekly conventional HD (CHD) were followed for one year. Radial-carotid pulse wave velocity, augmentation index and echocardiography were performed at baseline and 12th month. Mean age of the patients was 49±11 years, 30.8% were female, 27.5% had diabetes mellitus and mean dialysis vintage was 57±47 months. Baseline demographical, clinical and laboratory parameters were similar between groups. During a mean follow-up of 15.0±0.1 months, blood pressure remained similar in both groups while the number of mean daily anti-hypertensive substances decreased in the NHD group. In the NHD group, time-averaged serum phosphorus and calcium-phosphorus product were lower than the CHD group. Pulse wave velocity and augmentation index decreased in the NHD group (from 11.02±2.51 m/s to 9.61±2.39 m/s and from 28.8±10.3% to 26.2±12.1%; p=0.008 and p=0.04, respectively). While augmentation index increased in the CHD group (28.0±9.4 to 31.0±10.7%, p=0.02), pulse wave velocity did not change. Subendocardial viability ratio and ejection duration improved in the NHD group (from 135±28 to 143±25%, p=0.01 and from 294±34 ms to 281±34 ms, p=0.003, respectively), accompanied by regression of left ventricular mass index. In multiple stepwise linear regression analyses, NHD was associated with improvements in augmentation index, ejection duration and subendocardial viability ratio. These data indicate that arterial stiffness is ameliorated by implementation of longer hemodialysis sessions. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Recent reports on growth hormone (GH) therapy have shown that GH has various beneficial effects in GH deficient adults. In most of these studies, GH was administered daily. Because GH is still expensive and has to be delivered by subcutaneous injection, we studied the 6-month therapeutic effects of thrice weekly GH injection therapy and compared it with daily therapy. Twenty eight adult patients with GH deficiency were randomly assigned into group 1 (ten cases, thrice weekly injections of GH), group 2 (nine cases, daily injections), and group 3 (nine cases, placebo injections). Lean body mass, serum basal GH levels, and insulin-like growth factor 1 levels significantly increased after six months of GH therapy in both groups 1 and 2. According to computed tomography, the mean mid-thigh muscle mass significantly increased in group 1, while the visceral fat mass significantly decreased in group 2. GH levels significantly increased exercise rate-pressure product and hand grip strength only in group 1. These results suggest that thrice weekly injections of GH are as effective as daily injections in GH deficient adults. PMID:7986392

    Full Text Available Renal replacement therapy (RRT options and practice varies in countries worldwide and is influenced by patients' choice, nephrologists' practice patterns, health system, payer practice, public policy, and socioeconomic factors. In India, hemodialysis (HD remains the dominant RRT modality, and the practice is largely influenced by socioeconomics of the region of practice since third party payer is limited. Resource stretch to maximize outcome benefit is essential and HD session twice weekly is an improvized and cost-effective clinical practice. However, within the country, the patient characteristics, practice patterns, and outcomes of twice-weekly HD compared against patients dialyzed thrice weekly remain unclear. We did a retrospective analysis of patients who underwent twice- and thrice-weekly HD in a single center under similar settings. The patients on thrice a week dialysis were older and with a higher proportion of diabetics and were insured by private payers. Weight gain, ultrafiltration rates, blood pressures, and hemoglobin remained more favorable in the thrice-weekly patients. There was no significant difference in the hospitalization rates or mortality rates in the two groups. Patients who undergo twice-weekly HD have poorer intermediate measures of the outcome; although, morbidity and survival were not different in a small study population with short follow-up. The small sample size and the short duration of follow-up may limit the scope of findings of our study.

    Longer dialysis sessions may improve outcome in haemodialysis (HD) patients. We compared the clinical and laboratory outcomes of 8- and 4-h thrice-weekly HD. Two-hundred and forty-seven HD patients who agreed to participate in a thrice-weekly 8-h in-centre nocturnal HD (NHD) treatment and 247 age-, sex-, diabetes status- and HD duration-matched control cases to 4-h conventional HD (CHD) were enrolled in this prospective controlled study. Echocardiography and psychometric measurements were performed at baseline and at the 12th month. The primary outcome was 1-year overall mortality. Overall mortality rates were 1.77 (NHD) and 6.23 (CHD) per 100 patient-years (P = 0.01) during a mean 11.3 ± 4.7 months of follow-up. NHD treatment was associated with a 72% risk reduction for overall mortality compared to the CHD treatment (hazard ratio = 0.28, 95% confidence interval 0.09-0.85, P = 0.02). Hospitalization rate was lower in the NHD arm. Post-HD body weight and serum albumin levels increased in the NHD group. Use of antihypertensive medications and erythropoietin declined in the NHD group. In the NHD group, left atrium and left ventricular end-diastolic diameters decreased and left ventricular mass index regressed. Both use of phosphate binders and serum phosphate level decreased in the NHD group. Cognitive functions improved in the NHD group, and quality of life scores deteriorated in the CHD group. Eight-hour thrice-weekly in-centre NHD provides morbidity and possibly mortality benefits compared to conventional 4-h HD.

    In patients with end-stage renal disease (ESRD) treated with intermittent haemodialysis, a limited number of antibiotics have been studied for their suitability for parenteral administration after dialysis sessions only in a thrice-weekly regimen. Temocillin is a β-lactam antibiotic with a long half-live and enhanced activity against most Gram-negative bacteria, including extended-spectrum β-lactamase-producers, thus making it an ideal candidate for use in this setting. This study aimed to evaluate the reliability of thrice-weekly parenteral temocillin in haemodialysis patients by characterising the pharmacokinetics of total and free temocillin. Free and total temocillin concentrations were determined with a validated HPLC method in 448 samples derived from 48 administration cycles in 16 patients with ESRD treated with intermittent haemodialysis and temocillin. Pharmacokinetics were non-linear partly due to saturation in protein binding. Median clearance and half-life for the free drug during intradialysis and interdialysis periods were 113 mL/min vs. 26 mL/min and 3.6 h vs. 24 h, respectively, with dialysis extracting approximately one-half of the residual concentration. The free temocillin concentration remained >16 mg/L (MIC90 threshold for most Enterobacteriaceae) during 48%, 67% and 71% of the dosing interval for patients receiving 1 g q24h, 2 g q48h and 3 g q72h, respectively, suggesting appropriate exposure for the two latter therapeutic schemes. Temocillin administered on dialysis days only in a dosing schedule of 2 g q48h and 3 g q72h is appropriate for the treatment of serious and/or resistant Gram-negative infections in patients with ESRD undergoing intermittent haemodialysis. These doses are higher than those previously recommended. Copyright © 2015 Elsevier B.V. and the International Society of Chemotherapy. All rights reserved.

    Full Text Available Shortening tuberculosis (TB treatment duration is a research priority. This paper presents data from a prematurely terminated randomized clinical trial, of 4-month moxifloxacin or gatifloxacin regimens, in South India.Newly diagnosed, sputum-positive HIV-negative pulmonary TB patients were randomly allocated to receive gatifloxacin or moxifloxacin, along with isoniazid and rifampicin for 4 months with pyrazinamide for first 2 months (G or M or isoniazid and rifampicin for 6 months with ethambutol and pyrazinamide for first 2 months (C. All regimens were administered thrice-weekly. Clinical and bacteriological assessments were done monthly during treatment and for 24 months post-treatment. The Data and Safety Monitoring Board recommended termination of the trial due to high TB recurrence rates in the G and M regimens.Of 416 patients in intent-to-treat analysis, 6 (5% of 124, 2 (2% of 110 and 2 (2% of 137 patients with drug-susceptible TB in the G, M and C arms respectively had unfavorable response at the end of treatment; during the next 24 months, 17 (15% of 115, 11 (11% of 104 and 8 (6% of 132 patients respectively, had TB recurrence. Of 38 drug-resistant patients 1 of 8 and 3 of 26 in the G and C arms respectively had unfavourable response at the end of treatment; and TB recurrence occurred in 2 of 7 and 2 of 23 patients, respectively. The differences in TB recurrence rates between the G and C arms was statistically significant (p = 0.02. Gastro-intestinal symptoms occurred in 23%, 22% and 9% of patients in the G, M and C arms respectively, but most reactions were mild and manageable with symptomatic measures; 1% required regimen modification.4-month thrice-weekly regimens of gatifloxacin or moxifloxacin with isoniazid, rifampicin and pyrazinamide, were inferior to standard 6-month treatment, in patients with newly diagnosed sputum positive pulmonary TB.Clinical Trials Registry of India CTRI/2012/10/003060.

    Mycobacterium abscessus (M. abscessus) pulmonary disease is a refractory chronic infectious disease. Options for treating M. abscessus pulmonary disease are limited, especially in outpatient settings. Among parenteral antibiotics against M. abscessus, intravenous amikacin (AMK) is expected to be an effective outpatient antimicrobial therapy. This study evaluated the clinical efficacy and safety of intravenous AMK therapy in outpatients with M. abscessus pulmonary disease. This retrospective chart review of cases of M. abscessus pulmonary disease evaluated patient background data, AMK dosage and duration, sputum conversion, clinical symptoms radiological findings, and adverse events. M. massiliense was excluded on the basis of multiplex PCR assay. Thirteen patients (2 men and 11 women) with M. abscessus pulmonary disease were enrolled at 2 hospitals. The median age at the initiation of intravenous AMK treatment was 65 years (range: 50-86 years). Patients received a median AMK dose of 12.5 mg/kg (range: 8.3-16.2 mg/kg) for a median duration of 4 months (range: 3-9 months). The addition of intravenous AMK led to sputum conversion in 10 of 13 patients, and 8 patients continued to have negative sputum status 1 year after treatment. Approximately half of the patients showed improvement on chest high-resolution computed tomography. There were no severe adverse events such as ototoxicity, vestibular toxicity, and renal toxicity. Thrice weekly intravenous AMK administration in outpatient settings is effective and safe for patients with M. abscessus pulmonary disease.

    Full Text Available A 36-year old woman was referred to our Interstitial Lung Disease (ILD clinic for evaluation of dyspnea. A high-resolution CT scan of the chest showed perivascular reticular and ground glass opacities with air trapping, consistent with non-specific interstitial pneumonitis (Figure 1. She was diagnosed with connective tissue associated ILD. On review of previous images extensive subcutaneous calcifications were seen (Figure 2. Calcinosis is an uncommon manifestation of dermatomyositis in adults (1. It is usually seen around areas of frequent trauma like the hands and elbows. In her case, a pelvic inflammatory disease may have been a trigger for this calcinosis. Calcinosis is a difficult complication to treat with some success seen with diltiazem, aluminum hydroxide, and even alendronate in children. Surgical excision may be required in some cases.

  9. Neuropathy and efficacy of once weekly subcutaneous bortezomib in multiple myeloma and light chain (AL amyloidosis.

    Full Text Available Randomized studies have shown that bortezomib (BTZ can be given weekly via intravenous (IV route or twice weekly via subcutaneous (SC route with lower neuropathy risk and no loss of anti-myeloma efficacy compared to original standard IV twice weekly schedule. Weekly SC should therefore yield the best therapeutic index and is widely used but has not been compared to established administration schedules in the context of a clinical trial.Comprehensive electronic medical record review was done for disease control and neuropathy symptoms of 344 consecutive patients who received their first BTZ-containing regimen for myeloma or AL amyloidosis before or after we changed to SC weekly in December 2010. Univariate and multivariable analyses were carried out that adjusted for age, underlying disease, concurrently used anticancer agents, underlying conditions predisposing to neuropathy, and number of prior regimens compared SC weekly to other schedules.Fifty-three patients received BTZ SC weekly, 17 SC twice weekly, 127 IV weekly and 147 IV twice weekly. Risk for neuropathy of any grade was higher with other schedules compared to SC weekly (44.3% vs. 26.9%, p = 0.001 while response rate was similar (72.1% vs. 76.6%, respectively, p = 0.15. Multivariable analyses upheld higher neuropathy risk (Odds ratio 2.45, 95% CI 1.26-4.76, p = 0.008 while the likelihood of not achieving a response (= partial response or better was comparable (Odds ratio 1.25, 95% CI 0.58-2.71, p = 0.56 for other schedules compared to SC weekly, respectively. Lower neuropathy risk translated into longer treatment duration when BTZ was started SC weekly (p = 0.001.Weekly SC BTZ has activity comparable to other schedules and causes low rates of neuropathy.

  10. MEASURE FOR MEASURE: A THRICE TOLD TALE

    HALIMAH MOHAMED ALI

    2009-01-01

    Full Text Available This paper argues that Measure for Measure is a difficult play to perform because it has problematic themes, especially the theme of sexuality, that clash with the way of life and thinking of contemporary society. As such, any director who chooses to stage it must consider these difficulties and how to present them in a natural manner without making the audience feel that the whole production is contrived. The directors of the two major productions discussed in this paper tried their best to present a Measure for Measure that would be acceptable to the modern society. It is evident that there are many interpretations of the Duke and Isabella's characters and also of Isabella's reaction to the Duke's proposal at the end of the play. It can be concluded that no interpretation is wrong because each actor or director brings with him his own reading of the play, and every reading has been influenced by other performances and textual criticisms. Since Measure for Measure is a thematically rich play, it should not be confined to a single interpretation. The different performances of Measure for Measure have proven that theatre is experimental as well as ageless. Because it is a brilliant play with a myriad of interpretations, Measure for Measure will not cease to be a favourite for directors in times to come. It is not wrong to predict that fans of Shakespeare in general and of Measure for Measure in particular can look forward to many more productions.For experienced Shakespeare observers all performances are thrice-told tales. The perceiving eye absorbs the performance even as the mind's eye attends to the text. Both are augmented by the inner ear buzzing with those other voices, both critical and dramatic, carried by the observer into the theatre.(Crowl, Samuel 1992: 3

    To evaluate the long-term efficacy of triptorelin 3.75 mg subcutaneously every 6 weeks on the final height in girls with idiopathic central precocious puberty (ICPP). Forty females with ICPP received triptorelin 3.75 mg every 6 weeks subcutaneously in our hospital from 2002 to December 2010 and reached their final heights were enrolled. These patients were treated with triptorelin alone (group A, n=17) or triptorelin+recombinant human growth hormone (rhGH) (group B, n=23). Height, weight, annual growth velocity (GV), sexual development, predicted adult height (PAH), and adverse effects were observed. Bone age (BA) and height standard deviation score (SDS) were monitored yearly. Final adult heights (FAHs) were 159.81±1.20 cm and 161.01±1.02 cm in group A vs. group B, which exceeded target height (THt) by 1.51±1.04 cm, 4.86±0.94 cm, respectively. The values of (FAH-THt), (FAH-PAH posttreatment) showed significant difference between the two groups (pincreased after treatment in group B. However, there was no significant tendency of increase compared with healthy children at the same age. Ages of menarche and time to menarche from discontinuation were 11.74±0.16 vs. 12.18±0.15 years and 17.41±1.69 vs. 14.71±1.04 months in two groups. The FAH was improved effectively by triptorelin 3.75 mg subcutaneously every 6 weeks, and more height gain could be achieved when rhGH was used concomitantly. BMI maintained steadily and ovarian function restored quickly after treatment discontinuation with the age of menarche similar to that of normal children. Neither significant side effect nor polycystic ovary syndrome was observed.

    Teriparatide, a recombinant form of parathyroid hormone, were well recognized as a useful option for the treatment of the osteoporosis. Although some side effects of teriparatide include headache, nausea, dizziness, and limb pain were reported. Here we present a 80-year-old woman of transient asymptomatic hypotension with once-weekly subcutaneous injection of teriparatide for the treatment of osteoporosis with hypertension disease as acute-phase reactions. Systolic blood pressure decreased in both 30 min and 60 min after injection compared with before injection. Heart rate increased with passage of time. Statistically significant were observed among before, 30 min, 60 min after injection of teriparatide. Slight nausea was seen as subjective symptoms with the first and second injection after 30 min. This case indicates careful attention, at least 1 hr, was recommended with weekly subcutaneous injections of teriparatide in the treatment for osoteoproteic patient with hypertension decreases. This is a first report, to the best of our knowledge, to demonstrate the transient asymptomatic hypotension after once-weekly injection of teriparatide with hypertension disease. Transient hypotension occurred after injection of teriparatide during the treatment period and was asymptomatic except for the first 2 injections.

    Abstract OBJECTIVE: The aim of this study was to compare the metabolic effects of GH administered subcutaneously either once or twice daily. The actions of GH might depend upon a pulsatile pattern of serum GH. Pulsatile and continuous intravenous delivery of GH, however, induce similar short......-term metabolic effects in GH deficient patients. An improved growth response is obtained in GH deficient children when a fixed weekly GH dose is administered by daily subcutaneous injections instead of twice or thrice-weekly intramuscular injections. A more pulsatile pattern and serum GH levels above zero might...... be achieved by further increasing the injection frequency. Increased daytime GH levels might, however, adversely affect the circadian patterns of metabolic indices, which have been demonstrated to be more successfully reproduced by evening compared with morning GH administration.

    This thesis is about visualization and characterization of the tissue-device interaction during subcutaneous injection. The tissue pressure build-up during subcutaneous injections was measured in humans. The insulin pen FlexTouchr (Novo Nordisk A/S) was used for the measurements and the pressure...... build-up was evaluated indirectly from the changes in the flow rate between subcutaneous injections and air injections. This method enabled the tissue counter pressure to be evaluated without a formal clinical study approval. The measurements were coupled to a model for the pressure evolution...... in subcutaneous tissue, based on mass conservation and flow in a porous medium. From the measurements the flow permeability and bulk modulus of the tissue were determined. In the adipose tissue the drug forms a bolus from where it is absorbed by the blood capillaries. The spatial distribution of the injected...

AND METHODS: All the 28 Finnish patients participating in the Nordic multicentre trial on the clinical efficacy of weekly IFN-beta-1a (Rebif) 22 microg in SPMS were studied neurologically and by volumetric MRI during a 3-year follow-up. The levels of MMP-9 in serum were measured over the 3-year study. RESULTS......: There was no obvious effect on the number of contrast medium-enhancing lesions, the volume of T1 or T2 lesions or level of serum MMP-9, nor was any effect detected on the relapse rate and the Expanded Disability Status Scale (EDSS). Brain atrophy progression was not affected by the treatment. CONCLUSION: The lack...

    The advent of robotic surgery has increased the popularity of laparoscopic sacrocolpopexy. Carbon dioxide insufflation, an essential component of laparoscopy, may rarely cause massive subcutaneous emphysema, which may be coincident with life-threatening situations such as hypercarbia, pneumothorax, and pneumomediastinum. Although the literature contains several reports of massive subcutaneous emphysema after a variety of laparoscopic procedures, we were not able to identify any report of this complication associated with laparoscopic or robotic sacrocolpopexy. Massive subcutaneous emphysema occurred in 3 women after robotic sacrocolpopexy in our practice. The patients had remarkable but reversible physical deformities lasting up to 1 week. A valveless endoscopic dynamic pressure system was used in all 3 of our cases. Our objective is to define the risk of massive subcutaneous emphysema during robotic sacrocolpopexy in light of these cases and discuss probable predisposing factors including the use of valveless endoscopic dynamic pressure trocars.

    To evaluate the safety and efficacy of golimumab + methotrexate (MTX) in Japanese patients with active rheumatoid arthritis (RA). Japanese patients with active RA despite MTX were randomized to placebo + MTX (Group 1, n = 88), golimumab 50 mg + MTX (Group 2, n = 86), or golimumab 100 mg + MTX (Group 3, n = 87). Patients with <20% improvement in swollen/tender joint counts entered early escape at week 16. At week 24, all remaining placebo patients crossed over to golimumab 50 mg. Efficacy assessments included ACR20, DAS28-ESR, and HAQ-DI. Radiographic progression was assessed with the van der Heijde-modified Sharp (vdH-S) score. ACR20 response rates in Group 1, Group 2, and Group 3 were 67.9, 86.1, and 82.4%, respectively, at week 52 and were maintained through week 104 (87.1, 94.0, and 88.7%) and week 156 (97.1, 94.1, and 89.5%). Proportions of patients with good/moderate DAS28-ESR response or clinically meaningful improvement in HAQ-DI were also maintained through week 156. The majority of patients did not experience radiographic progression through week 156. Among 257 golimumab-treated patients, 251 (97.7%) had ≥1 AE; 54 (21.0%) had ≥1 serious AE through week 156. Infections were the most common type of AE. Response to golimumab + MTX was maintained over 3 years in Japanese patients with active RA despite MTX. Safety results were consistent with the known safety profile of golimumab.

  7. Factors affecting the abundance of leaf-litter arthropods in unburned and thrice-burned seasonally-dry Amazonian forests.

    Directory of Open Access Journals (Sweden)

    Juliana M Silveira

    Full Text Available Fire is frequently used as a land management tool for cattle ranching and annual crops in the Amazon. However, these maintenance fires often escape into surrounding forests, with potentially severe impacts for forest biodiversity. We examined the effect of experimental fires on leaf-litter arthropod abundance in a seasonally-dry forest in the Brazilian Amazon. The study plots (50 ha each included a thrice-burned forest and an unburned control forest. Pitfall-trap samples were collected at 160 randomly selected points in both plots, with sampling stratified across four intra-annual replicates across the dry and wet seasons, corresponding to 6, 8, 10 and 12 months after the most recent fire. Arthropods were identified to the level of order (separating Formicidae. In order to better understand the processes that determine arthropod abundance in thrice-burned forests, we measured canopy openness, understory density and litter depth. All arthropod taxa were significantly affected by fire and season. In addition, the interactions between burn treatment and season were highly significant for all taxa but Isoptera. The burned plot was characterized by a more open canopy, lower understory density and shallower litter depth. Hierarchical partitioning revealed that canopy openness was the most important factor explaining arthropod order abundances in the thrice-burned plot, whereas all three environmental variables were significant in the unburned control plot. These results reveal the marked impact of recurrent wildfires and seasonality on litter arthropods in this transitional forest, and demonstrate the overwhelming importance of canopy-openness in driving post-fire arthropod abundance.

    Full Text Available Subcutaneous zygomycosis, also known as basidiobolomycosis, is a rare disease caused by the fungus Basidiobolus ranarum. Since its first description in 1954, may cases have been reported. In India, so far only few cases have been described. We report this entity in a 3 year- old female child who had firm to hard swelling of the right upper extremely and chest. Histopathology showed short aseptate hyphae surrounded by eosinophilic material within the granulomatous tissue response, in the subcutaneous tissue. She responded dramatically to saturated solution of potassium iodide.

    Unlike in western countries, premixed insulin is widely used as the starter insulin in Asian patients instead of basal insulin. The use of basal-bolus therapy as an intensification regimen is not common in Asia despite poor glycaemic control after starting insulin therapy. An alternative insulin intensification regimen with a similar efficacy and safety profile to basal-bolus therapy, but of higher convenience, is urgently needed. The efficacy and safety of insulin lispro mix thrice-daily was compared with basal-bolus therapy in Asian patients with type 2 diabetes who were insufficiently controlled on twice-daily premixed insulin. This open-label, randomised, active comparator-controlled, parallel-group trial was done at 24 centres in China, Taiwan, and South Korea. Patients with type 2 diabetes who were inadequately controlled on twice-daily premixed insulin were randomly assigned (1:1) to receive either insulin lispro mix (mix 50 before breakfast and lunch plus mix 25 before dinner) or basal-bolus therapy (insulin glargine at bedtime plus prandial insulin lispro thrice-daily) for 24 weeks. Randomisation was done by a computer-generated random sequence and was stratified by country or region and baseline HbA1c. Treatment assignments were masked from the study team assessing outcomes but not from investigators and patients. The primary outcome was change from baseline in HbA1c at week 24 in all randomly assigned patients who received at least one dose of study drug. Analysis was by modified intention to treat, with the per-protocol population used as a supportive analysis. This study is registered with ClinicalTrials.gov, number NCT01175811. Between Feb 7, 2011, and Nov 7, 2012, 402 patients were enrolled (199 in the premix group, 203 in the basal-bolus group) and 399 were included in the primary analysis (197 in the premix group, 202 in the basal-bolus group). HbA1c change at week 24 was -1.1% for both treatment groups. The least squares mean difference between

    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.

  17. Subcutaneous adipose tissue classification

    2010-11-01

    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

    Oral amoxicillin (50 mg/kg/day) thrice daily is the first-line therapy for non-severe childhood pneumonia. Compliance could be enhanced if two daily doses are employed. We assessed the equivalence of oral amoxicillin (50 mg/kg/day) thrice or twice daily in those patients. This randomized (1 : 1), controlled, triple-blinded investigation conducted at one centre in Brazil included children aged 2-59 months with non-severe pneumonia diagnosed by trained paediatricians based on respiratory complaints and radiographic pulmonary infiltrate/consolidation. Participants were randomly assigned to receive one bottle (Amoxicillin 1) at 6 am, 2 pm and 10 pm and the other bottle (Amoxicillin 2) at 8 am and 8 pm: one bottle contained amoxicillin and the other placebo and vice versa. Only the pharmacist knew patients' allocation. Follow-up assessments were done at 2, 5 and 14 days after enrolment. Chest radiographs were read by three independent radiologists. Primary outcome was treatment failure (development of danger signs, persistence of fever, tachypnoea, development of serious adverse reactions, death and withdrawal from the trial) at 48 h. ClinicalTrials.gov: identifier NCT01200706. Four hundred and twelve and 408 participants received amoxicillin thrice or twice daily, respectively. Treatment failure was detected in 94 (22.8%) and 94 (23.0%) patients in intention-to-treat analysis (risk difference 0.2%; 95% CI: -5.5%-6.0%) and in 80 (20.1%) and 85 (21.3%) patients in per-protocol analysis (risk difference 1.2%; 95% CI: -4.4%-6.8%). Pneumonia was radiologically confirmed by concordant reading in 277 (33.8%) cases, among whom treatment failure was registered in 25/133 (18.8%) and 27/144 (18.8%) participants from the thrice and twice daily doses subgroups, respectively (risk difference -0.05%; 95% CI: -9.3%-9.2%). Oral amoxicillin (50 mg/kg/day) twice daily is as efficacious as thrice daily. © The Author 2014. Published by Oxford University Press on behalf of the British

    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.) With 3 figs., 17 refs.

    Objective To investigate whether compliance of patients to antibiotic treatment is better when antibiotics are administered once than multiple times daily. Methods We performed a systematic search in PubMed and Scopus databases. Only randomized controlled trials were considered eligible for inclusion. Compliance to antibiotic treatment was the outcome of the meta-analysis. Results Twenty-six studies including 8246 patients with upper respiratory tract infections in the vast majority met the inclusion criteria. In total, higher compliance was found among patients treated with once-daily treatment than those receiving treatment twice, thrice or four times daily [5011 patients, RR=1.22 (95% CI, 1.11, 1.34]. Adults receiving an antibiotic once-daily were more compliant than those receiving the same antibiotic multiple times daily [380 patients, RR=1.09 (95% CI, 1.02, 1.16)]. Likewise, children that received an antibiotic twice-daily were more compliant than those receiving the same antibiotic thrice-daily [2118 patients, RR=1.10 (95% CI, 1.02, 1.19)]. Higher compliance was also found among patients receiving an antibiotic once compared to those receiving an antibiotic of different class thrice or four times daily [395 patients, RR=1.20 (95% CI, 1.12, 1.28)]. The finding of better compliance with lower frequency daily was consistent regardless of the study design, and treatment duration. Conclusion This meta-analysis showed that compliance to antibiotic treatment might be associated with higher when an antibiotic is administered once than multiple times daily for the treatment of specific infections and for specific classes of antibiotics.

    Mesotherapy is an intradermal or subcutaneous injection of therapeutic agents to induce local effects, and was pioneered in Europe during the 1950s. For the past 2 decades, there has been significant interest in the use of mesotherapy for minimally invasive local fat contouring. Based on the theorized lipolytic effects of the agent phosphatidylcholine, initial attempts involved its injection into subcutaneous tissue. With further studies, however, it became apparent that the activity attributed to phosphatidylcholine mesotherapy was due to the adipolytic effects of deoxycholate, a detergent used to solubilize phosphatidylcholine. Since then, clinical trials have surfaced that demonstrate the efficacy of a proprietary formulation of deoxycholate for local fat contouring. Current trials on mesotherapy with salmeterol, a b-adrenergic agonist and lipolysis stimulator, are underway-with promising preliminary results as well. ©2015 Frontline Medical Communications.

    The introduction of totally implantable subcutaneous devices in the early 1980s provided patients with secure, reliable venous access and also gave them the ability to move more freely and have a more normal lifestyle with these devices in place. The most common totally implantable device used today is the subcutaneous port. These ports consist of an injection port connected to a catheter. Ports provide a number of advantages compared with other venous catheters; the most important is the reduced risk of infection. These devices have significantly lower rates of infection than nontunneled and tunneled catheters. Additional advantages include less frequent irrigation and minimal home care, and they are less prone to environmental or cutaneous contamination when not being accessed. This article will focus on the placement of these ports. Copyright © 2011 Elsevier Inc. All rights reserved.

    Spontaneous subcutaneous accumulations of air in the soft parts of the thorax during an asthmatic crisis (status asthmaticus) are rarely seen. The pathomechanism of the phenomenon, which may lead to the formation of an emphysema of the soft parts via the pneumomediastinum, is discussed, and the possible complications which must be taken into account are pointed out. The value of radiological examination of the thorax in children suffering from asthma bronchiale, is explained briefly. (orig.).

On histopathology of the local resection, a diagnosis of subcutaneous leiomyosarcoma was made. Specifically, leiomyosarcoma of the penile frenulum has not been clearly reported previously. The patient underwent a further excision to ensure an adequate resection margin and has had no disease recurrence at subsequent follow-up. Our case was of a lesion that, although clinically benign, was malignant and this possibility should be borne in mind when assessing patients.

    Abstract Subcutaneous bronchogenic cysts have been described rarely, particularly among adolescents. Only a few reports have described the ultrasonographic features of bronchogenic cysts, characterizing them as nonspecific cystic masses with or without internal echogenic foci or debris. Therefore, it is hard to differentiate subcutaneous bronchogenic cysts from other subcutaneous cystic tumors ultrasonographically. We report a case of presternal subcutaneous bronchogenic cyst in an 18-year-old man with unusual ultrasonographic findings. Ultrasonography revealed a small, oval, cystic mass containing a well-circumscribed, heterogeneously hypoechoic, egg-shaped lesion in the dependent portion of the mass within the subcutaneous fat layer overlying the sternum. Surgical excision was performed, and the cystic mass was diagnosed as a bronchogenic cyst. On pathological examination, the internal, heterogeneously hypoechoic, ball-like lesion was found to be mucous material within the cyst. To our knowledge, this is the first reported case of a presternal subcutaneous bronchogenic cyst presenting with a ball-like lesion inside of the cyst. This unusual ultrasonographic feature can be a clue to the diagnosis of subcutaneous bronchogenic cyst. In conclusion, if an anechoic cyst containing an internal, well-circumscribed, hypoechoic ball-like lesion is seen in the presternal subcutaneous fat layer, subcutaneous bronchogenic cyst should be considered in the differential diagnosis of subcutaneous cystic masses.

    Infectious endocarditis in children requires prolonged antibiotic therapy. In adults, antibiotics administrated subcutaneously such as teicoplanin are an alternative to intravenous treatment. We report the use of subcutaneous teicoplanin, after an initial antibiotic treatment administrated intravenously, for 2 children treated for infectious endocarditis following an initial cardiac surgery. Serum concentrations of teicoplanin were within the target range after the adaptation in the teicoplanin subcutaneous dosages. The treatment was effective for both cases. No specific side effects related to the treatment were reported. Subcutaneous administration could be used for prolonged antibiotic therapy for the treatment of infectious endocarditis in children, after an initial intravenous treatment. Variability of the bioavailability of antibiotics administrated subcutaneously requires regular testing. Prospective, randomized trials comparing intravenous and subcutaneous administration of teicoplanin should be conducted to assess the efficacy and safety of this treatment.

    Full Text Available A two-year-old spayed female mixed-breed dog was presented with a five-day history of hemorrhagic gastroenteritis and fever. On physical examination, the dog was lethargic and clinically dehydrated. The skin of the entire ventral abdomen extending to both flanks was erythematous, swollen and painful on palpation. Histopathological examination of skin biopsies revealed a severe diffuse neutrophilic dermatitis and panniculitis, resembling the subcutaneous form of Sweet’s syndrome in humans. A large part of the skin lesion developed full-thickness necrosis. After intensive care, three surgical wound debridements and wound adaptations, the wound healed by secondary intention within ten weeks. In the absence of infection of the skin or neoplasia, a diagnosis of neutrophilic dermatosis and panniculitis, resembling the subcutaneous form of acute febrile neutrophilic dermatosis, was made.

    Late biomaterial-centered infection is a major complication associated with the use of biomaterial implants. In this study biomaterials that had been implanted subcutaneously in rats were hematogenously challenged with bacteria 4 weeks after implantation. Bacteria were spread either by intravenous injection or by stimulation of bacterial translocation. It was found that none of the biomaterials was infected by hematogenous spread, whereas 5% of the implants were infected by perioperative contamination. We conclude that late hematogenous infection of subcutaneous biomaterials does not occur in the rat. For humans as well, there are growing doubts whether implants actually become infected through hematogenous routes; it is thought that late infections may be caused by delayed appearance of perioperatively introduced bacteria.

    Background: Subcutaneous emphysema and gas extravasation outside of the peritoneal cavity during laparoscopy has consequences. Knowledge of the circumstances that increase the potential for subcutaneous emphysema is necessary for safe laparoscopy. Methods: A literature review and a PubMed search are the basis for this review. Conclusions: The known risk factors leading to subcutaneous emphysema during laparoscopy are multiple attempts at abdominal entry, improper cannula placement, loose fitting cannula/skin and fascial entry points, use of >5 cannulas, use of cannulas as fulcrums, torque of the laparoscope, increased intra-abdominal pressure, procedures lasting >3.5 hours, and attention to details. New additional risk factors acting as direct factors leading to subcutaneous emphysema risk and occurrence are total gas volume, gas flow rate, valveless trocar systems, and robotic fulcrum forces. Recognizing this spectrum of factors that leads to subcutaneous emphysema will yield greater patient safety during laparoscopic procedures. PMID:24680136

    Generalized subcutaneous edema is an uncommon manifestation of inflammatory myopathy. We report a 48-year-old female patient who presented with severe generalized edema, an erythematous skin rash, dysphagia and proximal muscle weakness. She was diagnosed with dermatomyositis from the clinical signs, increased muscle enzymes, electromyographic findings and a muscle biopsy. Magnetic resonance imaging revealed increased signal intensity in the muscular and subcutaneous layers. The conditions causing generalized edema were excluded. It was concluded that the generalized edema was secondary to dermatomyositis. Aggressive treatments with high-dose glucocorticoids and immunosuppressive agents were used to control the severe subcutaneous edema.

    Major congenital malformations affect up to 3% of newborns. Infants with prenatally diagnosed soft tissue defects should benefit from having autologous tissue readily available for surgical implantation in the perinatal period. In this study, we investigate fetal subcutaneous cells (fSC) as cellular source for tissue engineering. Fetal subcutaneous biopsies were collected from elective terminations at gestational week 20-21. Cells were isolated, expanded and characterized in vitro. To determine cell coverage, localization, viability and proliferation in different constructs, the cells were seeded onto a matrix (small intestine submucosa (SIS)) or in collagen gel with or without poly(ε-caprolactone) (PCL) mesh and were kept in culture for up to 8 weeks before analysis. Angiogenesis was analyzed through a tube-forming assay. fSC could be expanded until 43±3 population doublings, expressed mesenchymal markers and readily differentiate into adipogenic and osteogenic lineages. The cells showed low adherence to SIS and did not migrate deep into the matrix. However, in collagen gels the cells migrated into the gel and proliferated with sustained viability for up to 8 weeks. The cells in the matrices expressed Ki67, CD73 and α-smooth muscle actin but not cytokeratin or CD31. Fetal cells derived from subcutaneous tissue demonstrated favorable characteristics for preparation of autologous tissue transplants before birth. Our study supports the theory that cells could be obtained from the fetus during pregnancy for tissue engineering purposes after birth. In a future clinical situation, autologous transplants could be used for reconstructive surgery in severe congenital malformations. This article is protected by copyright. All rights reserved.

  7. Intravenous and subcutaneous immunoglobulin G replacement therapy.

    Science.gov (United States)

    Bonilla, Francisco A

    2016-11-01

    Human polyclonal immunoglobulin G (IgG) for therapeutic use has been available for decades. This drug was developed for treatment of antibody deficiency (replacement therapy), although its use has expanded into many anti-inflammatory and immunomodulatory applications in recent years. This review focuses on IgG prescribing for replacement therapy. IgG for replacement is most often administered via the intravenous IgG (IVIG) or subcutaneous IgG (SCIG) routes. IVIG is usually administered every 34 weeks, and SCIG is usually administered weekly, although variations may be considered in all cases. Recently, a new product became available that uses hyaluronidase to facilitate absorption of large doses of SCIG less frequently (every 34 weeks, as with IVIG). There are important differences between the pharmacokinetics of these three routes of administration. IVIG therapy leads to high peaks and low troughs between infusions. IgG concentration fluctuates much less over time with SCIG. Hyaluronidase-facilitated SCIG is intermediate. SCIG may have lower bioavailability in comparison with IVIG and may require higher doses over time; this is not true for hyaluronidase SCIG. However, there are large variations in IgG half-life among individuals and with different products. Therefore, individualization of therapy is essential. Mild systemic flu-like adverse effects may affect up to 2025% of patients who receive IVIG, smaller fractions may experience more-severe symptoms, whereas anaphylaxis is exceedingly rare. General flu-like systemic adverse effects are minimal with SCIG (intermediate with hyaluronidase SCIG), but transient (24 hours), mild, local inflammatory symptoms at infusion sites are relatively common with both forms. Additional rare but important complications of IgG therapy include thrombotic events and hemolysis that can be seen at high doses with any route of administration. Renal adverse effects may occur with IVIG as well. The variety of IgG products and routes of

    Farah, Nadine

    2012-02-01

    OBJECTIVE: To determine if Fetal Abdominal Subcutaneous Tissue (FAST) measurements using antenatal ultrasound differ between male and female fetuses. STUDY DESIGN: Women who had an ultrasound examination for fetal growth between 20 and 40 weeks gestation were studied. Women with diabetes mellitus were excluded. The fetal anterior abdominal subcutaneous tissue was measured on the anterior abdominal wall in millimetres anterior to the margins of the ribs, using magnification at the level of the abdominal circumference. The fetal sex was recorded after delivery. RESULTS: A total of 557 fetuses were measured, 290 male and 267 female. The FAST measurements increased with gestational age. The FAST increased at the same rate for both male and female fetuses and at any given week there was no sex difference. CONCLUSIONS: The increased fat composition in females reported after birth was not found in abdominal wall subcutaneous fat measurements using ultrasound during pregnancy. Antenatal centile charts for FAST do not need to be based on sex.

    2015-01-01

    Targeted ultraviolet B (T-UVB) phototherapy in vitiligo is usually administered twice or thrice a week on non-consecutive days. It is difficult for many patients to adhere to this regimen, forcing them to discontinue treatment. The study aimed to compare the efficacy of twice-weekly and once-weekly targeted ultraviolet B phototherapy regimens in vitiligo. Sixty patients with non-segmental vitiligo on the face, neck or trunk were divided into two groups of 30 patients each. The patients in group A received targeted ultraviolet B twice weekly, while those in group B received targeted ultraviolet B once weekly. Repigmentation was monitored and graded as excellent (≥75% repigmentation), good (50-74% repigmentation) and poor (ultraviolet B administered was calculated and compared between both groups. A total of 90 lesions (48 in the twice weeklygroup and 42 in the once weekly group) were treated on the face, neck and trunk. Excellent results were obtained in 62.5% (30/48) of lesions treated twice weekly, and 64.3% (27/42) in lesions treated once weekly. The mean number of doses required for initiation of pigmentation was 4.69 in the twice weekly group, and 4.35 in the once weekly group. The patients in the twice weekly group received a mean cumulative dose of 8.26 J/cm 2, while the once weekly group received 7.69 J/cm2. No statistically significant differences were observed between the two groups with respect to the outcome, with respect to the total repigmentation, the number of doses till onset of pigmentation, as well as the cumulative dose of targeted UVB. Once-weekly targeted ultraviolet B phototherapy appears to be as efficacious as the twice-weekly regimen in vitiligo.

    The effect of 10 weeks of improved metabolic control on the impaired autoregulation of the subcutaneous blood flow was studied at the level of the lateral malleolus in eight long-term insulin-dependent diabetic patients with clinical microangiopathy. Blood flow was measured by the local 133-Xenon.......01, respectively). The slope of the subcutaneous blood flow autoregulation curves during poor metabolic control (median: 11.6% per 10 mmHg, range: 8.0-30.5% per 10 mmHg) was not significantly different from the slope values during improved metabolic control (13.4% per mmHg, 10.1-24.4% per mmHG). No association...... was demonstrated between the impaired autoregulation of subcutaneous blood flow and the metabolic parameters. Our results indicate that improved metabolic control for 10 weeks has no effect on the impaired autoregulation of subcutaneous blood flow in long-term insulin-dependent diabetic patients with clinical...

    This study was conducted to compare the efficacy of the subcutaneous epinephrine with nebulized salbutamol. Fifty asthmatic children in the age range of 6-14 years were divided into two equal groups. Group I children were given subcutaneous epinephrine and Group II were nebulized with salbutamol. Patients were observed at 15, 20, 30, 60, 120, 180 and 240 minute intervals. Both the groups had comparable mean increase in peak expiratory flow rate (PEFR %) (Group I 27.7 +/- 0.7; Group II 28.8 +/- 0.06, p >0.05). In Group I there was significant increase in systolic blood pressure, 30 minutes after the start of treatment, however it settled on its own by 60 minutes. Both the groups had satisfactory improvement in clinical parameters which continued upto 4 hours after start of treatment. Subcutaneous epinephrine can be safely used if nebulizers are not available.

  16. Hypertrophic Obesity and Subcutaneous Adipose Tissue Dysfunction

    Directory of Open Access Journals (Sweden)

    Anna Meiliana

    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.

    Warren et al1 set out to assess the effect of an intensified dosing schedule of subcutaneous methotrexate in patients with moderate to severe chronic plaque psoriasis. This is a prospective, double-blind, randomised (3:1), placebo-controlled study, conducted across 16 centres in Germany, France, the Netherlands, and the UK. Methotrexate-naïve adults with a diagnosis of moderate to severe chronic plaque psoriasis for at least 6 months before baseline were randomly assigned to receive weekly subcutaneous injections of either methotrexate at a starting dose of 17.5 mg, or placebo for 16 weeks (first phase).Dose escalation to 22.5 mg/week was implemented after 8 weeks if patients did not achieve PASI 50. Treatment was combined with folic acid 5 mg/week. The first phase of the study was followed by an open-label period from 16-52 weeks (second phase), in which both groups received weekly methotrexate injections. At week 24, dose escalation to 22.5 mg/week was possible in patients not achieving PASI 50. Psoriasis severity was measured using the PASI (Psoriasis Area and Severity Index). The authors also used two other psoriasis severity measures and two quality of life measures, looked at safety indices and performed a sub-study analysing paired skin biopsies at baseline and week 16 (histopathology, immunohistochemistry and expression of interleukin (IL)17A, interferon-γ and tumour necrosis factor-α). The primary outcome was the proportion of patients reaching PASI 75 at week 16. 120 patients were included in this trial, most of whom were middle-aged white men with longstanding psoriasis and a mean BMI of 30.1 kg/m2 . PASI 75 was achieved in 41% of patients receiving methotrexate vs. 10% of patients receiving placebo (RR 3.93, 95% CI 1.31-11.81; p=0.0026) at week 16. Subcutaneous methotrexate was generally well tolerated, with no serious adverse events related to this treatment over the 52-week study.

    BACKGROUND AND PURPOSE: Subcutaneous immunoglobulin (SCIG) is superior to placebo treatment for maintenance of muscle strength during 12 weeks in patients with chronic inflammatory demyelinating polyneuropathy (CIDP). The present study evaluated whether SCIG preserves muscle strength for 1 year...... evaluated after 3, 6 and 12 months. Primary end-points were changes in muscle strength evaluated by isokinetic dynamometry in four affected muscle groups and a composite score of muscle performance and function tests, including Medical Research Council (MRC) score, grip strength, 40-m walking test (40-MWT...... remained unchanged. CONCLUSION: SCIG preserves muscle strength and functional ability in patients with CIDP who previously responded to IVIG. SCIG should be considered as an alternative in long-term treatment of CIDP patients....

    Full Text Available We present the case of a 40-year-old woman with a small diffuse swelling on the left side of her face. She was diagnosed with intramuscular cysticercosis in the masseter muscle (case of disseminated cysticercosis involving the muscular system and subcutaneous tissues with surrounding phlegmon on high-resolution ultrasound and managed conservatively. To our knowledge, the imaging findings of disseminated muscular cysUcercosis have been reported before only a few numbers of times. In this case, the correct diagnosis was made on the basis of high-resolution sonography of the subcutaneous tissue and muscles. It showed multiple oval to circular, predominantly anechoic lesions, which were around 1 cm in diameter. Most of these cystic lesions showed a hyperechoic focus within suggestive of a scolex. There was no increased vascularity surrounding the lesions. Thus, sonography can primarily make the correct diagnosis of disseminated muscular cysticercosis if such lesions are seen. In endemic areas, cysticercosis should be considered one of the differential diagnosis of the subcutaneous swellings.

    The purpose of this in vivo study was to investigate revascularization and root growth after autotransplantation of cryopreserved immature teeth. Immature molar teeth were extracted in 4-week-old Wistar rats. In the test group, teeth were cryopreserved for 1 week and transplanted subcutaneously to the abdomen. In the control group, teeth were transplanted subcutaneously immediately after extraction. Material was collected in test and control animals at intervals of 1, 2, 4 and 10 weeks post-transplantation and histological and microradiographical examination was performed. Results showed that during the first weeks after transplantation, pulpal repair was similar in both groups although degenerated pulpal tissue was replaced slower in cryopreserved teeth and some differences in types of hard tissue formation were found between test and control teeth. After 10 weeks, the differences in the regenerated pulpal tissue between cryopreserved and control teeth observed during the first weeks were no longer detectable. No root growth was detected microradiographically 10 weeks after transplantation in any of the transplanted teeth. The presence of dentin-like tissue in the pulp cavity of some autotransplanted cryopreserved teeth, suggests survival of pulpal tissue after cryopreservation. Copyright © 2011 Elsevier Inc.

    Sarcoidosis is a systemic granulomatous disease of unknown origin that mainly involves lung and skin, but rarely involves subcutaneous tissue. While some studies have reported on CT or MR imaging findings of subcutaneous sarcoidosis, there is only one report on sonographic findings of subcutaneous sarcoidosis, recently published in the US. Familiarity with ultrasonographic findings of subcutaneous sarcoidosis might be helpful for the early diagnosis in patient with palpable nodules and image follow-up for subcutaneous sarcoidosis. Here we report on the sonographic appearance of subcutaneous sarcoidosis involving dermal and subcutaneous tissue over axilla and sole, a case diagnosed as sarcoidosis and improved by steroid treatment, along with a review of the relevant literature.

Methods Thirty seven Sprague-Dawley (SD rats were randomly divided into model group (n=27 and control group (CN group, n=10. Rats in model group were fed with high glucose diet for 6 weeks. Twenty rats having developed IR in the model group were further randomly divided into two groups: IR group (n=10 and melatonin group (MLT group, n=10. Rats in CN group and MLT group were fed with 10mg/(kg.d of standard chow or MLT, respectively, for 6 weeks from the beginning of the 7th week. At the end of the 12th week, the subcutaneous fat tissue was harvested from bilateral inguinal areas of the rats for the evaluation of the protein and mRNA expression of Lep by immunohistochemistry and RTPCR. Results Systolic blood pressure (SBP, fasting serum leptin (Lep, triglycerides (TG, low density lipoprotein cholesterol (LDL-C, malondialdehyde (MDA and homeostasis model assessment insulin resistance (HOMA-IR were significantly lower (P0.05. The protein and mRNA expressions of Lep in subcutaneous adipose tissue were significantly higher in IR group than in CN group (P<0.01, while they were significantly lower in MLT group than in IR group (P<0.01. Conclusion MLT may improve IR and the status of oxidation stress, and inhibit the over expression of Lep protein and mRNA in subcutaneous fat tissue in the high-glucose diet-induced IR rats.

    A study was carried out in order to obtain further information about the soft tissue response to thin Apaceram discs of dense hydroxyapatite (HA) implanted in rats for various periods of time between one day and 10 months. The Apaceram discs were implanted subcutaneously into the interscapular region of 33 rats. A sham operation was performed on eight rats used as controls. Decalcified histological sections stained with haematoxylin and eosin and Mallory's azan were examined and the different cell types found around the implants were counted. It was found that an acute inflammatory reaction occurred after one day and disappeared at about two weeks after implantation. In the test groups, macrophages and lymphocytes disappeared about one week later, and no inflammatory reaction was observed from one to three months. However, a tissue reaction occurred at six months with the appearance of macrophages and lymphocytes, and decreased gradually at 10 months. Meanwhile, a few foreign body giant cells at the Apaceram-tissue interface and a thick layer of fibrous connective tissue around the Apaceram disc were observed at 10 months. No osteogenesis was observed in any specimen. The results obtained so far suggest that Apaceram is still a useful material for reconstructive surgery, despite the possible appearance of a slight macrophage reaction at six 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.

    Full Text Available Stephen Jolles Department of Immunology, University Hospital of Wales, Cardiff, UK Abstract: Immunoglobulin (Ig-replacement therapy represents the mainstay of treatment for patients with primary antibody deficiency and is administered either intravenously (IVIg or subcutaneously (SCIg. While hyaluronidase has been used in clinical practice for over 50 years, the development of a high-purity recombinant form of this enzyme (recombinant human hyaluronidase PH20 has recently enabled the study of repeated and more prolonged use of hyaluronidase in facilitating the delivery of SC medicines. It has been used in a wide range of clinical settings to give antibiotics, local anesthetics, insulin, morphine, fluid replacement, and larger molecules, such as antibodies. Hyaluronidase has been used to help overcome the limitations on the maximum volume that can be delivered into the SC space by enabling dispersion of SCIg and its absorption into lymphatics. The rate of facilitated SCIg (fSCIg infusion is equivalent to that of IVIg, and the volume administered at a single site can be greater than 700 mL, a huge increase over conventional SCIg, at 20–40 mL. The use of fSCIg avoids the higher incidence of systemic side effects of IVIg, and it has higher bioavailability than SCIg. Data on the long-term safety of this approach are currently lacking, as fSCIg has only recently become available. fSCIg may help several areas of patient management in primary antibody deficiency, and the extent to which it may be used in future will depend on long-term safety data and cost–benefit analysis.

    The murine calvarial model has been widely employed for the in vivo study of particle-induced osteolysis, the most frequent cause of aseptic loosening of total joint replacements. Classically, this model uses an open surgical technique in which polyethylene (PE) particles are directly spread over the calvarium for the induction of osteolysis. We evaluated a minimally invasive modification of the calvarial model by using a direct subcutaneous injection of PE particles. Polyethylene (PE) particles were injected subcutaneously over the calvaria of C57BL6J ten-week-old mice ("injection" group) or were implanted after surgical exposure of the calvaria ("open" group) (n = 5/group). For each group, five additional mice received no particles and served as controls. Particle-induced osteolysis was evaluated two weeks after the procedure using high-definition microCT imaging. Polyethylene particle injection over the calvaria resulted in a 40% ± 1.8% decrease in the bone volume fraction (BVF), compared to controls. Using the "open surgical technique", the BVF decreased by 16% ± 3.8% as compared to controls (p Polyethylene particle implantation by injection is less invasive and reliably induces osteolysis to a greater degree than the open technique. This subcutaneous injection method will prove useful for repetitive injections of particles, and the assessment of potential local or systemic therapies.

    A 6-year-old neutered male domestic short-haired cat was presented to the Comparative Ophthalmology service at Michigan State University with a 3-week history of decreased appetite and redness of the left eye. The left forelimb had been removed 15 months previously because of the presence of a subcutaneous fibrosarcoma. In the left globe, a large iridal mass was associated with increased intraocular pressure and retinal detachment. A smaller mass involving the right iris was also present. Imaging revealed a 2-cm mass in the left caudodorsal lung lobe, and abdominal ultrasound showed multifocal bilateral renal masses. Aspirates of these masses were nondiagnostic. The left globe was removed for palliative reasons, and histopathology showed that fibrosarcoma was infiltrating the iris, choroid, and optic nerve. Despite systemic chemotherapy with doxorubicin, the animal died 4 months after initial presentation. Histopathology confirmed highly angioinvasive metastatic fibrosarcoma also in the right uveal tract, the lungs, and both kidneys. © 2012 American College of Veterinary Ophthalmologists.

    Full Text Available The early administration of methotrexate (MTX and the use of its high (by the rheumatology practice standards doses contribute to the enhanced efficiency of therapy and the reduced severity of rheumatoid arthritis (RA. One of the important merits of MTX in the treatment of RA is the possibility of adjusting its dose and choosing its (oral or subcutaneous administration routes, which makes it possible to individualize treatment. Particular emphasis has been recently placed just on a subcutaneous MTX formulation that creates prerequisites for substantially improving the efficiency of RA therapy. The paper gives the data of the REMARCA (Russian investigation of methotrexate and biologicals for early active arthritis trial assessing the results of RA treatment in the use of the subcutaneous MTX dosage form as a first-line drug and in the elaboration of management tactics for this disease.Subjects and methods. The investigation included 191 patients (34 men and 157 women with active RA; of whom 51.8% had very early RA (< 6 months' disease duration. 115 patients with RA completed a 24-month follow-up period; and their data were analyzed in more detail.Results and discussion. The findings may substantiate treatment policy based on the prescription of subcutaneous MTX (without previously administering its oral formulation in patients with early RA and high disease activity, starting the drug at 15 mg/week and rapidly escalating with the highest tolerable doses during 4-8 weeks, which allows remission (or low disease activity in the majority of patients without using glucocorticoids and biological agents.

    Full Text Available There are many indications for excretory urography in humans and animals. Intravenous urography (IVU is the most practical method about other urography techniques are used because of difficulties for finding veins in IVU, due to small size of the patients. This study was performed to evaluate the feasibility of subcutaneous injection of iodixanol in providing a safe and diagnostic urogram in Persian squirrel. Twelve clinically healthy adult Persian squirrels were prepared and kept for two weeks prior to study. Blood tests were performed 7 days prior to the study. After eighteen hour fasting, animals were sedated by using xylazine/diazepam cocktail (xylazine 5mg/kg, diazepam 30mg/kg. Lateral and ventrodorsal control radiographs were taken. Thirteen hundred and 1800 mg iodine per kilogram body weight of iodixanol was injected subcutaneously over shoulder area in Persian squirrels (each dose for six Persian squirrels. Lateral and ventrodorsal radiographs were taken every 5 minutes until the pyelogram was finished. Blood tests were performed 5 days after the study. Histopathologic samples were taken from skin, kidneys, ureters and urinary bladder. The kidneys of squirrels were bean-shaped and their size was approximately 1.7×0.8 cm in ventrodorsal view for both kidneys. Subcutaneous injection of iodixanol was successful to show pyelogram, uretrogram and cystogram but it was unsuccessful in showing nephrogram without pyelogram except in one case (8.33%. Good pictures of nephrograms, calices and the ureters were obtained approximately 70 min after injection. There were no abnormal clinical signs after one week of experiment. There were no abnormal blood chemistry and hematological changes. Urinary system and skin microscopic examinations were normal. It is concluded that subcutaneous urography is an effective and reliable method for urography studies in squirrel except for nephrogram. More investigations are needed to study reasons for the lack of

    Determine the safety and tolerance of mesotherapy as a technique for the treatment of musculoskeletal complaints in musicians. 67 patients (55.2% women) were subjected to a total of 267 mesotherapy sessions. A mesotherapy needle or normal needle was used randomly. The drugs employed were thiocolchicoside and diazepam as muscular relaxants, pentoxifylline or buflomedil as vasodilators, and piroxicam as an anti-inflammatory, as directed. A visual analogue scale was used to quantify the pain produced by the microinjections as well as the degree of immediate and midterm side effects as reported on a standard questionnaire. A mean of 155.5 microinjections were performed per session, of which 45.6% were perceived as painful by the patient with a mean severity of 4.3 out of 10. The pain reduced to 0.5 out of 10 after 24 hours. The most sensitive areas were the levator scapulae and splenius muscles. Systemic symptoms were reported by 5.99% of the musicians after the mesotherapy sessions (muscular weakness 1.5%, rash 1.5%, drowsiness 1.1% and itching 1.1%, being the most frequent). The mean severity of these symptoms was 2.77 out of 10. In all cases the symptoms had completely disappeared after 24 hours. No patient referred to signs of local or systemic infection. The application of drugs by means of subcutaneous injections (mesotherapy) in musicians is a technique that is safe, well tolerated, and without any severe complications.

An increasing number of individuals with diabetes mellitus individuals of all ages have started using insulin pump therapy. Not everyone is a good candidate for insulin pump therapy, and the clinician needs to be able to determine which patients are able to master the techniques required and to watch for the adverse reactions that may develop. Insulin pump increases quality of life of patient with diabetes mellitus with increasing satisfaction with treatment and decrease impact of diabetes mellitus. Manual errors by insulin pump users may lead to hypo or hyperglycemia, resulting into diabetic ketoacidosis (DKA sometimes. Some of practical aspect is associated with insulin pump therapy such as selection of candidates, handling of pump and selection of site, and pump setting, henceforth this review is prepared to explore and solve the practical problems or issues associated with pump therapy.

    Sarcoidosis is a granulomatous multisystemic disorder that rarely involves subcutaneous tissue. We describe the MR imaging findings of a subcutaneous sarcoidosis in a patient that presented with a nontender, palpable soft tissue mass on the left buttock, which was confirmed after surgical excision. The MR images showed the presence of a subcutaneous mass that breached the adjacent fascia with an irregular outline and homogeneous, slightly higher signal intensity than the surrounding muscle as seen on a T2-weighted image and with homogeneous enhancement after contrast injection. The lesion could not be differentiated from a sarcoma or a malignancy.

    Subcutaneous facial emphysema after dental treatment is an uncommon complication caused by the invasion of high-pressure air; in severe cases, it can spread to the neck, mediastinum, and thorax, resulting in cervical emphysema, pneumomediastinum, and pneumothorax. The present case showed subcutaneous cervicofacial emphysema with pneumomediastinum after class V restoration. The patient was fully recovered after eight days of conservative treatment. The cause of this case was the penetration of high-pressure air through the gingival sulcus, which had a weakened gingival attachment. This case indicated that dentists should be careful to prevent subcutaneous emphysema during common dental treatments using a high-speed hand piece and gingival retraction cord.

    Subcutaneous mastectomy has a possible role as prophylaxis in patients at high risk of developing breast cancer. A case history is presented of a woman who developed metastatic breast carcinoma 42 years after bilateral subcutaneous mastectomies for non-malignant disease. This case is presented to draw attention to the persistent risk of developing breast cancer even decades after subcutaneous mastectomy and to point out that the role of such surgery in preventing breast cancer has still not been clarified. The appropriateness of prophylactic mastectomy for an individual is better assessed on the absolute risk of breast cancer developing over a defined period rather than the relative risk.

    Cysticercosis is an infection caused by the metacestode larval stage of Taenia parasites in tissues and elicits a host-parasite reaction in which the immune response may be decisive in the disease development. The aim of this study was to evaluate the role of IFNγ (IFN-gamma) in the experimental model of subcutaneous infection with Taenia crassiceps (T. crassiceps) cysticerci using IFNγ knockout mice. Male C57BL/6 and C57BL/6 KO IFNγ mice 8-12 weeks of age were inoculated with T. crassiceps cysticerci into the subcutaneous tissue of the dorsum. At 7 and 30 (acute phase), 60 and 90 (chronic phase) days post infection, animals from each group had their blood and the subcutaneous tissues collected for serologic and pathological studies. IFNγ and IL-4 were dosed and the histopathological analysis was performed. In the presence of IFNγ there was the establishment of a mixed Th1/Th2 systemic immune profile. This profile also locally induced the granuloma formation which was constituted by cells that played important roles in the parasitary destruction and that were likely associated to the Th1 axis of mixed immune response. On the other hand, the absence of IFNγ appears to favor the parasitary growth which may be related to the development of a systemic Th2 immune response. This profile influenced the granuloma formation with immunoregulatory properties and appears to be important in the collagen synthesis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Pretibial myxedema (PTM) is a rare extrathyroidal manifestation of Graves' disease that requires treatment when the clinical picture is markedly evident. In addition to topical treatment with steroid ointments, there have been previous reports of subcutaneous injections of steroids. This procedure may cause nodular degeneration of the skin due to fat atrophy when standard needles are used. In the present study, we have tried a novel modality of treatment of PTM by injecting a solution of dexamethasone in the subcutaneous tissue using needles employed for mesotherapy. These needles are ≤4 mm long and deliver the medication within the dermis or the first layer of the subcutaneous fat. We have treated five patients, four with diffuse and one with elephanthiasic PTM. We utilized multiple injections of a solution of dexamethasone, lidocaine, and saline in the PTM plaque and in the pretibial area, both in the PTM plaque and in the area surrounding the lesions, once a week for three consecutive weeks. Two patients with a more severe form of PTM underwent another two cycles four to six weeks after initial treatment. Patients were studied before and after treatment by clinical assessment and ultrasound of the pretibial skin. The treatment was well-tolerated, with only moderate pain upon injection of the solution. One month after treatment, all patients showed improvement of PTM at clinical assessment and a reduction of the thickness of the lesions at ultrasound of ∼15%, involving mostly the dermis. Moreover, all patients reported amelioration of the leg appearance. The present study, although preliminary, shows that intralesion steroid injection with mesotherapy needles in PTM is effective and well tolerated, and does not cause undesired long-term modifications of the skin. More studies are warranted to standardize such treatment in larger groups of patients.

    Implantable cardioverter-defibrillators (ICDs) are important tools in the prevention of sudden death, but implantation requires transvenous access, which is associated with complications. Subcutaneous implantable cardioverter-defibrillators (S-ICDs) may prevent some of these complications. To evaluate the therapeutics and complications associated with S-ICD systems. S-ICD implantation was planned in 23 patients, for whom the indications were vascular access problems, increased risk of infection or young patients with long predicted follow-up. The population consisted of four patients with ischemic heart disease, three of them on hemodialysis (two with subclavian vein thrombosis), five with left ventricular noncompaction, four with Brugada syndrome, three with arrhythmogenic right ventricular cardiomyopathy, one with transposition of the great vessels, two with dilated cardiomyopathy and four with hypertrophic cardiomyopathy. S-ICDs were implanted in 21 patients, two having failed to fulfil the initial screening criteria. Mean implantation time was 77 minutes, with no complications. Defibrillation tests were performed, and in one patient the generator had to be repositioned to obtain an acceptable threshold. In a mean follow-up of 14 months, 10 patients had S-ICD shocks, which were appropriate in half of them; one developed infection, one needed early replacement due to loss of telemetry and one patient died of noncardiac cause. S-ICD implantation can be performed by cardiologists with a high success rate. Initial experience appears favorable, but further studies are needed with longer follow-up times to assess the safety and efficacy of this strategy compared to conventional devices.

    Full Text Available OBJECTIVES: To compare treatment persistence between two dosages of interferon β-1a in a large observational multiple sclerosis registry and assess disease outcomes of first line MS treatment at these dosages using propensity scoring to adjust for baseline imbalance in disease characteristics. METHODS: Treatment discontinuations were evaluated in all patients within the MSBase registry who commenced interferon β-1a SC thrice weekly (n = 4678. Furthermore, we assessed 2-year clinical outcomes in 1220 patients treated with interferon β-1a in either dosage (22 µg or 44 µg as their first disease modifying agent, matched on propensity score calculated from pre-treatment demographic and clinical variables. A subgroup analysis was performed on 456 matched patients who also had baseline MRI variables recorded. RESULTS: Overall, 4054 treatment discontinuations were recorded in 3059 patients. The patients receiving the lower interferon dosage were more likely to discontinue treatment than those with the higher dosage (25% vs. 20% annual probability of discontinuation, respectively. This was seen in discontinuations with reasons recorded as "lack of efficacy" (3.3% vs. 1.7%, "scheduled stop" (2.2% vs. 1.3% or without the reason recorded (16.7% vs. 13.3% annual discontinuation rate, 22 µg vs. 44 µg dosage, respectively. Propensity score was determined by treating centre and disability (score without MRI parameters or centre, sex and number of contrast-enhancing lesions (score including MRI parameters. No differences in clinical outcomes at two years (relapse rate, time relapse-free and disability were observed between the matched patients treated with either of the interferon dosages. CONCLUSIONS: Treatment discontinuations were more common in interferon β-1a 22 µg SC thrice weekly. However, 2-year clinical outcomes did not differ between patients receiving the different dosages, thus replicating in a registry dataset derived from "real

    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.

    Subcutaneous blood flow was measured preceding insulin-induced hypoglycaemia, at the onset of hypoglycaemic symptoms and 2 h later in juvenile diabetics with and without autonomic neuropathy and in normal males. 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....

    Subcutaneous generalized edema associated with dermatomyositis (DM)/polymyositis (PM) is extremely rare. Herein we report a case of severe subcutaneous generalized edema complicating DM. A 78-year-old woman was hospitalized in our department because of massive edema in the four limbs. Elevated muscle enzymes, heliotrope rash, results of electromyography, and muscle biopsy confirmed the diagnosis of DM. The absence of other diseases that could cause the symptoms indicated that massive edema was correlated with the pathophysiology of DM. Although myopathy and edema responded well to oral prednisolone, dysphagia persisted. We conclude that subcutaneous generalized edema can occur during the course of DM/PM, and subcutaneous vasculopathy may be involved in the pathogenesis of DM/PM.

    2014-01-01

    Protein and peptide drugs administered subcutaneously, such as insulin can be amyloidogenic and result in localized amyloid deposits at the sites of medication injections. These iatrogenic amyloidoses typically present as a localized subcutaneous nodule or skin reaction at the site of administration, and often pose diagnostic challenges. We have analyzed the amyloid proteome in 52 cases of insulin and enfuvirtide associated amyloidosis using laser microdissection/tandem mass spectrometry. We ...

    Circadian rhythms underlie many immune responses and allergic diseases. Subcutaneous immunotherapy (SCIT) can result in adverse reactions; however, it is unclear whether such reactions have a diurnal pattern. To assess whether the timing of SCIT affects the rate of adverse reactions. This study was a retrospective medical record review of adult patients (n = 289) who received SCIT at the Northwestern Medical Faculty Foundation, Chicago, Illinois, during a 10-year period (2004-2014). Injections were given in the outpatient setting. There were a total of 17,457 injections with 574 reactions. Covariates included age, sex, median income, asthma status, vial contents, number of injections, and previous immunotherapy reactions. Logistical regression was used to calculate the odds of having a reaction with time of SCIT administration as the primary determinate. Immunotherapy reactions occurred more frequently after afternoon or evening (pm) injections (328/8721 = 3.8%) vs morning (am) injections (246/8736 = 2.8%), (χ2 = 12.26, P < .01). Systemic reactions, defined as World Allergy Organization grade 1 or higher, did not have diurnal variation (59/8721 = 0.67% for pm vs am 56/8736 = 0.64% for morning; χ2 = 0.08; P = .77). pm injections resulted in higher odds of reaction compared with am injection in a fully adjusted logistic regression model (odds ratio = 1.43; 95% confidence interval, 1.20-1.70; P < .01). When considering time as 4 categories, the highest odds of reaction were noted for the period from 15:01 to 17:30 (odds ratio, 1.55; 95% confidence interval, 1.21-2.00; P < .01). pm injections of SCIT are associated with increased cutaneous reaction rates when compared with am injections. In patients experiencing bothersome local reactions, it may be beneficial to administer SCIT in the morning. Copyright © 2016 American College of Allergy, Asthma & Immunology.

    Although physical therapy can help preserve mobility in patients with systemic sclerosis (SSc), stretching has not been used systematically as a treatment to prevent or reverse the disease process. We previously showed in rodent models that stretching promotes the resolution of connective tissue inflammation and reduces new collagen formation after injury. Here, we tested the hypothesis that stretching would impact scleroderma development using a mouse sclerodermatous graft-versus-host disease (sclGvHD) model. The model consists in the adoptive transfer (allogeneic) of splenocytes from B10.D2 mice (graft) into Rag2(-/-) BALB/c hosts (sclGvHD), resulting in skin inflammation followed by fibrosis over 4 weeks. SclGvHD mice and controls were randomized to stretching in vivo for 10 min daily versus no stretching. Weekly ultrasound measurements of skin thickness and subcutaneous tissue mobility in the back (relative tissue displacement during passive trunk motion) successfully captured the different phases of the sclGvHD model. Stretching reduced skin thickness and increased subcutaneous tissue mobility compared to no stretching at week 3. Stretching also reduced the expression of CCL2 and ADAM8 in the skin at week 4, which are two genes known to be upregulated in both murine sclGvHD and the inflammatory subset of human SSc. However, there was no evidence that stretching attenuated inflammation at week 2. Daily stretching for 10 min can improve skin thickness and mobility in the absence of any other treatment in the sclGvHD murine model. These pre-clinical results suggest that a systematic investigation of stretching as a therapeutic modality is warranted in patients with SSc.

    A warm and early October afternoon saw the beginning of the 2005 ATLAS overview week, which took place Rue de La Montagne Sainte-Geneviève in the heart of the Quartier Latin in Paris. All visitors had been warned many times by the ATLAS management and the organisers that the premises would be the subject of strict security clearance because of the "plan Vigipirate", which remains at some level of alert in all public buildings across France. The public building in question is now part of the Ministère de La Recherche, but used to host one of the so-called French "Grandes Ecoles", called l'Ecole Polytechnique (in France there is only one Ecole Polytechnique, whereas there are two in Switzerland) until the end of the seventies, a little while after it opened its doors also to women. In fact, the setting chosen for this ATLAS overview week by our hosts from LPNHE Paris has turned out to be ideal and the security was never an ordeal. For those seeing Paris for the first time, there we...

    Oral methotrexate (MTX) has been a first line systemic agent in the treatment of chronic plaque psoriasis (CPP) for more than 50 years. Parenteral MTX, administered as a subcutaneous (SC) injection has gained favour in recent years. The effectiveness of SC MTX has been proven in rheumatological conditions but there has been no assessment of its role in CPP. We retrospectively reviewed case notes of 85 patients prescribed SC MTX for psoriasis in three dermatology centres in the UK (Betsi Cadwaladr University Health Board, Western Infirmary, Glasgow, and Salford Royal NHS Foundation Trust). Audit department approval was sought and granted. A total of 85 patients (44 male; 41 female; age range 14 - 78 years, mean 44 years; 79 Caucasian, 6 Asian) with CPP were identified. The average duration of psoriasis was 19 years [range 3 - 60 years]. Co-morbidities included depression, diabetes mellitus, hypertension, epilepsy, obesity, ischaemic heart disease, and hyperlipidaemia; 29 patients had no associated co-morbidities. Psoriatic arthritis was noted in 18 patients. Previous treatments included phototherapy (both narrow band ultraviolet B [TLO1] and psoralen and ultraviolet A [PUVA])(n=60), oral MTX (n=82), ciclosporin (n=37), acitretin (n=19), fumaric acid esters (n=20), hydroxycarbamide (n=6), mycophenolate mofetil (n=2), and repeated in-patient admissions (n=2). Oral MTX was stopped due to nausea (n=43), ineffectiveness (n=13) or partial response (n=11), headache (n=3), increased liver enzymes (n=2), and lethargy (n=2). The median number of systemic agents used prior to SC MTX was 3 (mean 2.65, range 1 to 6 agents). The weekly dose of SC MTX varied between 7.5mg to 30 mg (mean 18.5mg, median 20mg) and had been used for 2 months to 67 months (mean 14 months; median 9 months). Folic acid supplementation was used in every patient. The patients were reviewed between 6 weeks to 3 months once treatment was fully established. Using a pre-determined "adjective list" (where

    Full Text Available We analyzed the influence of inflammatory macrophages on the osteogenic process in subcutaneous implants composed of mineral bone substitute. Thioglycollate-elicited peritoneal macrophages (TEPMs were characterized as inflammatory. This was confirmed microscopically by the nitroblue tetrazolium (NBT test and the production of tumor necrosis factor α (TNF-α. The implants (M-type were made of mineral bone substitute (Bio-Oss® mixed with TEPMs and blood clot. Implants without macrophages served as the control (C-type. Subcutaneous implantation in the interscapular area was performed on BALB/c mice. Implants were extracted after 2 and 8 weeks. In M-type implants, phagocytosis and angiogenesis were more pronounced, and osteoblast-like cells aligned onto granules of implanted material and osteoid structures can be seen. The observed higher osteocalcin and lower osteopontin immunoexpression in M-type implants when compared to the control after 8 weeks suggest a more advanced osteogenic process. Our results indicate that the presence of inflammatory macrophages in the composition of an implant may have a beneficial effect on the osteogenic process.

    Full Text Available Background: Long-acting therapy in laboratory animals offers advantages over the current practice of 2-3 daily drug injections. Yet little is known about the disintegration of biodegradable drug implants in rodents. Objective: Compare bioavailability of buprenorphine with the biodegradation of lipid-encapsulated subcutaneous drug pellets. Methods: Pharmacokinetic and histopathology studies were conducted in BALB/c female mice implanted with cholesterol-buprenorphine drug pellets. Results: Drug levels are below the level of detection (0.5 ng/mL plasma within 4-5 days of implant. However, necroscopy revealed that interstitial tissues begin to seal implants within a week. Visual inspection of the implant site revealed no evidence of inflammation or edema associated with the cholesterol-drug residue. Chemical analyses demonstrated that the residues contained 10-13% of the initial opiate dose for at least two weeks post implant. Discussion: The results demonstrate that biodegradable scaffolds can become sequestered in the subcutaneous space. Conclusion: Drug implants can retain significant and unintended reservoirs of drugs.

    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.

    BACKGROUND AND PURPOSE: 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...... 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. RESULTS: 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...

    To evaluate non-adherence to prescribed subcutaneous biologicals in rheumatoid arthritis (RA) patients in Spain. ARCO (Study on Adherence of Rheumatoid Arthritis patients to SubCutaneous and Oral Drugs) was a multicentre, non-interventional retrospective study involving 42 rheumatology clinics from representative hospitals throughout Spain. The primary objective was to assess the percentage of patients (aged ≥18 years with an established RA diagnosis) with non-adherence to prescribed subcutaneous biologicals using clinical records and hospital pharmacy dispensing logs as the primary information sources. Adherence was assessed using the Medication Possession Ratio (MPR). Additionally, patients completed the Morisky-Green Medication Adherence Questionnaire. A total of 364 patients (77.5% females, mean age 54.9 years, median RA duration since diagnosis 7.8 years) were enrolled in ARCO. Non-adherence (MPR ≤80%) was reported in 52/363 evaluable patients (14.3%), and was lower in patients receiving initial monthly drug administration (6.4%) than with weekly (17.4%; p=0.034) or every two weeks (14.4%; p=0.102) administration. By multivariate analysis, non-adherence was positively associated with RA duration above the median and with using induction doses. Monthly administration, compared to weekly administration, was inversely associated with non-adherence. Age, gender, order of administration, and changes in the interval of administration, showed no association with non-adherence. Compared with the MPR, the Morisky-Green questionnaire performed poorly in detecting non-adherence. Non-adherence to the prescribed subcutaneous biological drug occurred in 14.3% of patients with RA. Patients using the most convenient administration period (i.e. monthly) had better adherence than those using more frequent dosing schedules.

    Full Text Available Intentional subcutaneous injection of mercury by mentally healthy children is rare. Usually, it is seen as a part of suicidal attempt in severely depressed patients or by athletes to enhance their performance. We report a case of a 15-year-old child, inspired by a movie, who deliberately self-injected mercury subcutaneously into his forearm that led to the formation of a non-healing ulcer. Histopathology of the biopsy confirmed the diagnosis. A surgical procedure was thereby performed to treat the ulcer and reduce the blood and urinary levels of mercury. However, the patient did not develop clinical signs of chronic poisoning, proving that subcutaneous mercury injection has a low risk of systemic toxicity, and that histopathology plays an important role in diagnosis.

    2002-02-01

    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.

    Limb subcutaneous emphysema secondary to a Munchausen syndrome represents a rare and severe entity because it involves the functional prognosis of the limb and vital prognosis of the patient. We report the case of an 18-year-old Moroccan woman patient who presented to our hospital with a subcutaneous emphysema of the shoulder girdle and the right arm, caused by our patient. Treatment was aggressive, with a wide surgical debridement, parenteral antibiotic therapy and hyperbaric oxygen therapy. The results have been favorable. The correlation of anamnestic data and clinical and para-clinical exams were essential for the diagnosis of Munchausen syndrome in this case. In this regard, we report a rare case of subcutaneous limb emphysema secondary to Munchausen syndrome.

    Although periorbital edema is a common manifestation of dermatomyositis (DM), generalized subcutaneous edema associated with DM is extremely rare. Evans syndrome is an autoimmune disease in which an individual's antibodies attack one's own red blood cells and platelets. Evans syndrome is rarely a presenting feature of DM. DM has been rarely reported to be associated with either generalized edema or Evans syndrome. We report the case of a 52-year-old Korean woman who presented with generalized subcutaneous edema, an erythematous rash, dysphagia, and proximal muscle weakness, and subsequently developed features of Evans syndrome.

    Gentileschi, Stefano; Servillo, Maria; Salgarello, Marzia

    2015-10-01

    Postsurgical subcutaneous lymphocele is caused by accidental lesion of a lymphatic vessel that keeps on flowing lymph under the scar. Traditional treatments include aspiration and compression, with probable recurrence, and sclerotherapy which destroys both lymphatic cyst and vessel, creating risk of lymphedema. We describe the case of a postsurgical subcutaneous lymphocele of the left leg that was treated by supramicrosurgical lympatic-venous anastomosis. A single anastomosis was performed end-to-end, between one lymphatic vessel, individuated through indocyanine green lymphography, and one subcutaneous vein, distally to the lymphocele, under sedation and local anesthesia. Postoperative course was uneventful; the lymphocele completely resolved and never recurred during the nine months followup. This technique may heal the lymphocele with no impairing of lymph drainage function. © 2015 Wiley Periodicals, 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.

    Abstract The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No

    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.

    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 Lipid composition and sensory traits of the meat from female lambs of the Pantaneiro genetic group slaughtered with 2.00, 3.00 and 4.00 mm of subcutaneous fat thickness (SFT were evaluated by ultrasound. Twenty-four lambs weighing 16.24 ± 1.78 kg were confined in feedlots. These animals were fed with pelleted diet formulated to provide a daily weight gain of 0.30 kg. As the lambs reached the pre-set SFT in the weekly evaluation by ultrasound, they were slaughtered on the day following the measurement, regardless of their weight. The SFT did not alter the fatty acid profile of meat from Pantaneiro lambs. For the sensory analysis, the meat from the animals slaughtered with 4.00 mm SFT received the best score for variables overall acceptance and characteristic flavor as compared with the females slaughtered with 2.00 mm SFT. The treatment with 3.00 mm SFT, however, did not differ from the others. For sensory traits odor and juiciness, no effect of SFT was found. It is recommended to slaughter lambs with 3.00 mm thickness of subcutaneous fat on the loin, because covered better number of favorable attributes in sensory analysis.

    2011-01-01

    Background Although fascial bands within the subcutaneous (SQ) layer are commonly seen in ultrasound images, little is known about their functional role, much less their structural characteristics. This study's objective is to describe the morphological features of SQ fascial bands and to systematically evaluate the bands using image analyses tools and morphometric measures. Methods In 28 healthy volunteers, ultrasound images were obtained at three body locations: the lateral aspect of the upper arm, medial aspect of the thigh and posterior aspect of lower leg. Using image analytical techniques, the total SQ band area, fascial band number, fascial band thickness, and SQ zone (layer) thickness were determined. In addition, the SQ spatial coherence was calculated based on the eigenvalues associated with the largest and smallest eigenvectors of the images. Results Fascial bands at these sites were contiguous with the dermis and the epimysium forming an interconnected network within the subcutaneous tissue. Subcutaneous blood vessels were also frequently encased by these fascial bands. The total SQ fascial band area was greater at the thigh and calf compared to the arm and was unrelated to SQ layer (zone) thickness. The thigh was associated with highest average number of fascial bands while calf was associated with the greatest average fascial band thickness. Across body regions, greater SQ zone thickness was associated with thinner fascial bands. SQ coherence was significantly associated with SQ zone thickness and body location (calf with statistically greater coherence compared to arm). Conclusion Fascial bands are structural bridges that mechanically link the skin, subcutaneous layer, and deeper muscle layers. This cohesive network also encases subcutaneous vessels and may indirectly mediate blood flow. The quantity and morphological characteristics of the SQ fascial band may reflect the composite mechanical forces experienced by the body part. PMID:21931632

    Visceral fat induces more inflammation by activating macrophages than subcutaneous fat, and inflammation is an underlying feature of the pathogeneses of various diseases, including cardiovascular disease and diabetes. Advanced glycation end products (AGEs), S100β, and their receptors, the receptor for advanced glycation end products (RAGE), lead to macrophage activation. However, little information is available regarding the differential accumulations of AGE-albumin (serum albumin modified by AGEs), S100β, or expressions of RAGE in different adipocyte types in fat tissues. In this study, the authors investigated whether age-related AGE-albumin accumulations S100β level, and RAGE expressions differ in subcutaneous and visceral fat tissues. Subcutaneous and visceral fat were harvested from 3- and 28-week-old rats. Macrophage activation was confirmed by Iba1 staining, and AGE-albumin accumulations and RAGE expressions were assessed by confocal microscopy. S100β were analyzed by immunoblotting. It was found that activated macrophage infiltration, AGE-albumin accumulation, and S100β in visceral fat was significantly greater in 28-week-old rats than in 3-week-old rats, but similar in subcutaneous fat. The expression of RAGE in visceral fat was much greater in 28-week-old rats, but its expression in subcutaneous fat was similar in 3- and 28-week-old rats. Furthermore, inflammatory signal pathways (NFκB, TNF-α) and proliferation pathways (FAK) in visceral fat were more activated in 28-week-old rats. These results imply that age-related AGE-albumin accumulation, S100β, and RAGE expression are more prominent in visceral than in subcutaneous fat, suggesting that visceral fat is involved in the pathogenesis of inflammation-induced diseases in the elderly. - Highlights: • The age-related AGE-albumin accumulation and S100β were more prominent in visceral than subcutaneous fat. • The age-related RAGE expression were more prominent in visceral than subcutaneous fat.

    Carrier erythrocytes administered subcutaneously in mice release encapsulated molecules at the injection site and through cells that escape the injection site. One day postinjection, the efflux of encapsulated (/sup 14/C)sucrose, (/sup 3/H)inulin, and /sup 51/Cr-hemoglobin from the injection site was 45, 55, and 65%, respectively. Intact carrier erythrocytes escaped the injection site and entered the blood circulation carrying with them the encapsulated molecules. Most of the encapsulated (/sup 3/H)inulin that reached whole blood circulated within erythrocytes. Small but measurable numbers of encapsulated molecules were trapped within lymph nodes. Subcutaneous injection of carrier erythrocytes may allow for limited extravascular tissue targeting of drugs.

    2016-06-01

    Novel data for the conductivities of the tissues composing the skin, which are the epidermis, dermis and subcutaneous tissue, were obtained at intermediate frequencies by in vitro measurement. The conductivity of the epidermis was determined from those of the dermis and bulk skin. The conductivities of the dermis and subcutaneous tissue were almost constant from 10 kHz to 1 MHz. On the other hand, a frequency dependence was observed for the epidermis; the conductivity decreases with decreasing frequency. It was found that the conductivity of bulk skin is not determined by that of the dermis but by that of the epidermis. The presented data are expected to contribute to the assessment of safety and to the research and development of medical applications.

    2012-06-01

    Full Text Available An 11 year – old mixed female Labrador was presented with two masses in trunk and neck. The tumoral masses were excised and sent for histopathological and immunohistochemical analyses. Histopathological examination of masses revealed diffuse infiltration of small sized lymphoid cells in subcutaneous tissue which were intense around the blood vessels. More than 10% lymphoid cells were CD3 positive in the immunohistochemical staining and most of them were accumulated around vessels. Protein 53 (p53 expression was detected by brown nuclei in immunohistochemical staining. Subcutaneous lymphoma was diagnosed according to histopathological results. After 6 months the case was referred with multicentric lymphoma and based on the owner request euthanasia was performed. These findings emphasize on poor prognosis for tumors with p53 mutation.

Currently, systemically delivered local anesthetics are being used for the evaluation and treatment of neuropathic pain. We present a case describing the treatment of spasticity of spinal origin with continuous subcutaneous infusion of 0.75% bupivacaine in a patient who did not respond to traditional treatments and has become tolerant to intrathecal baclofen.

  19. Subcutaneous pedicle propeller flap: An old technique revisited and modified!

    Directory of Open Access Journals (Sweden)

    Durga Karki

    2016-01-01

    Full Text Available Background: Post-burn axillary and elbow scar contracture is a challenging problem to the reconstructive surgeon owing to the wide range of abduction and extension that should be achieved, respectively, while treating either of the joint. The aim of this paper is to highlight the use of subcutaneous pedicle propeller flap for the management of post-burn axillary and elbow contractures. Methodology: This is a prospective case study of axillary and elbow contractures managed at a tertiary care hospital using propeller flap based on subcutaneous pedicle from 2009 to 2014. Surgical treatment comprised of subcutaneous-based pedicle propeller flap from the normal tissue within the contracture based on central axis pedicle. The flap was rotated axially to break the contracture. The technique further encompassed a modification, a Zig-Zag incision of the flap, which was seen to prevent hypertrophy along the incision line. There was a mean period of 12 months of follow-up. Results: Thirty-eight patients consisting of 22 males and 16 females were included in this study among which 23 patients had Type II axillary contractures and 15 had moderate flexion contractures at elbow joint. The post-operative abduction achieved at shoulder joint had a mean of 168° whereas extension achieved at elbow had a mean of 175°. The functional and aesthetic results were satisfactory. Conclusion: The choice of surgical procedure for reconstruction of post-burn upper extremity contractures should be made according to the pattern of scar contracture and the state of surrounding skin. The choice of subcutaneous pedicle propeller flap should be emphasised because of the superior functional results of flap as well as ease to learn it. Moreover, the modification of propeller flap described achieves better results in terms of scar healing. There is an inter-positioning of healthy skin in between the graft, so it prevents scar band formation all around the flap.

    Full Text Available Subcutaneous panniculitis-like T-cell lymphoma (SPTCL; α/β T-cell subtype is a distinct variantof cutaneous T-cell lymphomas, which presents as inflammatory subcutaneous nodules. A 17-year-old male presented with recurrent fever with concomitant facial swelling, pedal edema, hepatosplenomegaly, and mildly tender subcutaneous plaques in generalized distribution along with patches of scarring alopecia on scalp. There were features of macrophage activation syndrome in the form of hemophagocytosis in the bone marrow, pancytopenia, high serum lactate dehydrogenase levels, low fibrinogen clotting activity, prolonged activated prothrombine time (aPTT, increased serum ferritin, hypoalbuminemia, and hypertriglyceridemia. Histopathology showed lobular panniculitis-like infiltration by atypical lymphocytes rimming the adipocytes. Immunohistochemistry revealed positive CD3 and CD8 markers, whereas CD4, CD56, and CD20 were negative, consistent with the diagnosis of α/β type of SPTCL. Treatment with oral prednisolone (1mg/kg/day and cyclosporine (2mg/kg/day; 100 mg led to rapid subsidence of fever, plaques, and abnormal hematological parameters within a few weeks.

    Diffuse-type giant cell tumor is an extra-articular form of pigmented villonodular synovitis. The localized form of this lesion (tenosynovial giant cell tumor) is frequent, representing the most common subset arising from the synovium of a joint, bursa or tendon sheath, with 85% of cases occurring in the fingers. The less frequent diffuse-type giant cell tumors are commonly located in the periarticular soft tissues, but on rare occasions these lesions can be purely intramuscular or subcutaneous We report the case of a 26-year-old female with diffuse-type giant cell tumor of the subcutaneous thigh, remote from a joint, bursa or tendon sheath. A review of the literature did not reveal any similar description of a diffuse-type giant cell tumor completely within the subcutaneous thigh, remote from a joint, bursa or tendon sheath. These lesions were initially regarded as inflammatory or reactive processes, but since the identification of clonal abnormalities in these patients, and in view of their capacity for autonomous growth, they are now widely considered to represent benign neoplasms.

    Full Text Available Introduction. The most prominent complications of cocaine use are adverse effects in the cardiovascular and central nervous systems. Free air in the mediastinum and subcutaneous tissue may be observed less frequently, whereas free air in the spinal canal (pneumorrhachis is a very rare complication of cocaine abuse. In this report we present a case of pneumorrhachis that developed after cocaine use. Case. A 28-year-old male patient was admitted to the emergency department with shortness of breath, chest pain, and swelling in the neck and face which started four hours after he had sniffed cocaine. On physical examination, subcutaneous crepitations were felt with palpation of the jaw, neck, and upper chest area. Diffuse subcutaneous emphysema, pneumomediastinum, and pneumorrhachis were detected in the computed tomography imaging. The patient was treated conservatively and discharged uneventfully. Discussion. Complications such as pneumothorax, pneumomediastinum, and pneumoperitoneum that are associated with cocaine use may be seen due to increased intrathoracic pressure. The air then may flow into the spinal canal resulting in pneumorrhachis. Emergency physicians should know the possible complications of cocaine use and be prepared for rare complications such as pneumorrhachis.

    Insufficient oxygenation can limit the long-term survival of encapsulated islets in subcutaneous tissue. Transplantation of coencapsulated pig islets with adipose or bone marrow mesenchymal stem cells (AMSCs or BM-MSCs, respectively) was investigated with regard to implant vascularization, oxygenation, and diabetes correction in primates. The in vivo impact of MSCs on graft oxygenation and neovascularization was assessed in rats with streptozotocin (STZ)-induced diabetes that were subcutaneously transplanted with islets coencapsulated with AMSCs (n = 8) or BM-MSCs (n = 6). Results were compared to islets encapsulated alone (n = 8). STZ diabetic primates were subcutaneously transplanted with islets coencapsulated with BM-MSCs (n = 4) or AMSCs (n = 6). Recipients were monitored metabolically and immunologically, and neoangiogenesis was assessed on explanted grafts. Results were compared with primates transplanted with islets encapsulated alone (n = 5). The cotransplantation of islets with BM-MSCs or AMSCs in diabetic rats showed significantly higher graft oxygenation than islets alone (3% and 3.6% O2 for islets + BM-MSCs or AMSCs, respectively, vs. 2.2% for islets alone). A significantly better glycated hemoglobin correction (28 weeks posttransplantation) was found for primates transplanted with islets and MSCs (7.4% and 8.1%, respectively) in comparison to islets encapsulated alone (10.9%). Greater neoangiogenesis was found in the periphery of coencapsulated islets and AMSCs in comparison to islets alone (p pig islets with MSCs can improve significantly the islets' survival/function in vitro. The coencapsulation of islets with MSCs improves implant oxygenation and neoangiogenesis. However, the cotransplantation of islets with MSCs improves only slightly the long-term function of a subcutaneous bioartificial pancreas in a primate preclinical model.

    Full Text Available A multi-centre, non-comparative study examining the efficacy and safety of Subgam, a normal immunoglobulin (IgG given weekly as a rapid subcutaneous infusion to patients with primary immune deficiency (PID, is reported. Also included is a summary of adverse drug reactions associated with the use of marketed Subgam in the UK.50 patients with stable PID on IgG therapy were enrolled: Stage 1 included three infusions with prior IgG product followed by 6 months with Subgam, Stage 2 involved long-term Subgam therapy up to 4 years.Stage 1, 85% of the subjects aged >12 years and 93% of the subjects aged <12 years achieved IgG levels ≥6 and ≥4 g/L, respectively at all observations. There were 3.62 infections/patient/year during Subgam treatment. The most common product-related events were infusion site reactions (50% of patients. Recent post-hoc pharmacokinetics analysis of the post-infusion serum total IgG concentration indicated that the mean dose-normalised incremental IgG AUCτ following intravenous dosing (120.5 g.day/L was 1.64-fold that of the dose-normalised mean incremental IgG AUCτ following subcutaneous dosing (73.6 g.day/L, corresponding to an estimated IgG bioavailability for subcutaneous dosing of 61%. Only 34 post-licensing adverse reactions have been received in 30 patients over a period of 10 years; fourteen were classed as serious as defined by the ICH guidelines on good clinical practice. The most common post-licensing adverse reaction was infusion site reaction (7 reports. There were 7 reports of flu-like symptoms (pyrexia/shivering/rigors/feeling hot or cold, 2 other reports of combined flu-like symptoms and infusion site reactions, 5 reports of generalised skin reactions, and 3 reports of combined infusion site and skin reactions. There were also reports of anaphylaxis (2 reports and 8 other adverse events (including headache. In conclusion, Subgam is effective and well tolerated in the treatment of PID.ClinicalTrials.gov NCT

    2015-10-01

    Full Text Available Introduction The relevance of allergic rhinitis is unquestionable. This condition affects people's quality of life and its incidence has increased over the last years. Objective Thus, this study aims to analyze the effectiveness of subcutaneous injectable immunotherapy in cases of nasal itching, sneeze, rhinorrhea and nasal congestion in allergic rhinitis patients. Methods In the present study, the same researcher analyzed the records of 281 patients. Furthermore, the researchers identified allergens through puncture cutaneous tests using standardized extracts containing acari, fungi, pet hair, flower pollen, and feathers. Then, the patients underwent treatment with subcutaneous specific immunotherapy, using four vaccine vials for desensitization, associated with environmental hygiene. The authors analyzed conditions of nasal itching, sneeze, rhinorrhea, and nasal congestion throughout the treatment, and assigned them with a score ranging from zero (0, meaning absence of these symptoms to three (3, for severe cases. The symptoms were statistically compared in the beginning, during, and after treatment. Results In this study, authors analyzed the cases distribution according to age and the evolution of symptomatology according to the scores, comparing all phases of treatment. The average score for the entire population studied was 2.08 before treatment and 0.44 at the end. These results represent an overall improvement of ∼79% in symptomatology of allergic rhinitis in the studied population. Conclusion The subcutaneous immunotherapy as treatment of allergic rhinitis led to a reduction in all symptoms studied, improving the quality of life of patients, proving itself as an important therapeutic tool for these pathological conditions.

    To describe the characteristic US and MR findings of subcutaneous epidermal inclusion cysts. Seventy-nine patients with subcutaneous epidermal inclusion cysts underwent US (n = 70), MR (n = 7), or both (n = 2). On US, the margin, shape, echogenicity, through-transmission, wall, internal debris and vascularity were evaluated. On MR, the shape, wall, signal intensity, internal debris, and enhancement pattern were evaluated. On US, characteristic findings were well circumscribed (n = 69, 96%), ovoid-shaped (n = 56, 78%), heterogeneously and mildly echogenic (n = 66, 92%), increased through-transmission (n = 66, 92%) and low echoic rim (n = 48, 67%). Internal debris was seen in 31 cases (43%) and often contained linear echogenic reflections (n = 12, 17%), dark clefts (n = 13, 18%), or a mixture (n = 5, 7%). Most masses showed no Doppler flow (n = 70, 97%). On MR, all cases demonstrated a well-demarcated oval-shaped mass with a surrounding rim. On T1-weighted image (WI), the mass showed slightly high T1 signal in 4/9 (44%) and iso-signal in 5/9 (56%). On T2WI, the mass showed high signal in 6/9 (67%), intermediate in 2/9 (22%), and a target appearance in 1/9 (11%). Internal linear dark T2 signal debris was observed in 4/9 (44%). All lesions showed peripheral rim enhancement without central enhancement. On US, subcutaneous epidermal inclusion cysts are usually well-circumscribed, oval-shaped, mildly echogenic masses with occasional linear anechoic and/or echogenic reflections, increased through-transmission, hypoechoic rim and no Doppler flow. On MR, an intermediate to high T2 signal mass with occasional low signal debris and no central enhancement can strengthen the diagnosis. (orig.)

  10. The use of subcutaneous infusion in medication administration.

    Science.gov (United States)

    Gabriel, Janice

    The subcutaneous administration of medications is an area that receives little attention compared with other types of parenteral therapy. Parenteral administration is used by many thousands of patients who self-administer their medication on a daily basis-for example, those using insulin to manage diabetes, recipients of some types of hormone therapy and so on. It is also an effective route for the continuous administration of medication(s) in individuals who are terminally ill. Patients approaching the end of their life may be unable to tolerate the administration of oral medication to control their symptoms and make them more comfortable. This paper will discuss how subcutaneous infusion can be used to deliver these medications, but at the same time how important the selection of the most appropriate subcutaneous infusion device is to the overall comfort of the patient, and to reduce the potential for sharps-related injuries to healthcare workers. Appropriate device selection, together with its management, is an important contributing factor to patient safety and comfort. It will diminish the potential for premature device loss, which can lead to repeated insertion procedures for the patient, as well as delaying their medication. There is also a resource implication for the NHS, as the replacement of any device involves the use of additional equipment and staff time. Additionally, the use of any infusion device poses a risk to healthcare workers of acquiring a bloodborne infection should they experience a percutaneous injury. Knowledge of what equipment is available will reduce the potential risk to these staff.

    It is still unclear whether the longitudinal anal muscles or conjoint longitudinal coats (CLCs) are attached to the vagina, although such an attachment, if present, would appear to make an important contribution to the integrated supportive system of the female pelvic floor. Using immunohistochemistry for smooth muscle actin, we examined semiserial frontal sections of 1) eleven female late-stage fetuses at 28-37 weeks of gestation, 2) two female middle-stage fetus (2 specimens at 13 weeks), and, 3) six male fetuses at 12 and 37 weeks as a comparison of the morphology. In late-stage female fetuses, the CLCs consistently (11/11) extended into the subcutaneous tissue along the vaginal vestibule on the anterior side of the external anal sphincter. Lateral to the CLCs, the external anal sphincter also extended anteriorly toward the vaginal side walls. The anterior part of the CLCs originated from the perimysium of the levator ani muscle without any contribution of the rectal longitudinal muscle layer. However, in 2 female middle-stage fetuses, smooth muscles along the vestibulum extended superiorly toward the levetor ani sling. In male fetuses, the CLCs were separated from another subcutaneous smooth muscle along the scrotal raphe (posterior parts of the dartos layer) by fatty tissue. In terms of topographical anatomy, the female anterior CLCs are likely to correspond to the lateral extension of the perineal body (a bulky subcutaneous smooth muscle mass present in adult women), supporting the vaginal vestibule by transmission of force from the levator ani.

    Full Text Available The records of patients from the Allergology Service in the Previsora Policlinic, Camagüey were revised to evaluate benefits and risks of the subcutaneous immunotherapy (ITSC with extracts of acari. The study was observational, analytic and retrospective of cases and controls in allergic rhinoconjunctivitis and bronchial asthma. A total of 160 subjects, older than 18 years old, were chosen. Eighty out of them had already received ITSC with dose increase during 13 weeks and maintenance with monthly injections during 18 months. A total of 80 patients who only received prevention measures and medications during the crises were paired. Questionnaires were applied for quality of rhinoconjunctivitis life and asthma, about the consumption of medications and the frequency of the crises. The adverse events were measured, as they were local and systemic to the cutaneous tests, to the ITSC and the different pharmacological treatments. There was a significant increase of the punctuation of life quality questionnaires, (p=0.011. The consumption of medications decreased in both the cases and the controls, without significant differences (p=0.083. The frequency of the rhinitis and asthma crises decrease in the group of ITSC (p=0.029. Slight local and systemic reactions were reported in both groups with Odds ratio (OR=2.029 in the ITSC group, with a 95% confidence interval of 1.114–3.967 (p=0.019. The results show that the subcutaneous immunotherapy with acari offers benefits and few risks to patients with allergic rhinoconjunctivitis and asthma.

To this team it is necessary specific knowledge and abilities, as well as continuous update of the processes that involve such care. This article has as objective to make some considerations about this subject, adjusting them to the common nursing practice. For this, we present a literature review that approaches the main application methods used for subcutaneous medication. After that, we argue some aspects for professional improvement, so that the medication administration be satisfactory and safe in the caring process.

    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. This trial is registered with ClinicalTrials.gov, number NCT01200758; new

    Combined continuous subcutaneous insulin infusion (CSII) and metformin (M) was tested in 10 overweighted insulin requiring diabetic patients (body mass index 27.9 +/- 4.9 kg/m2). They were still poorly controlled (HbA1 9.6 +/- 0.8%) despite large doses of lente insulin (Novo) (51.7 +/- 19.6 IU/24 h) injected once daily. With CSII after two weeks on placebo (P) they were enrolled in a randomized double blind cross-over trial with two successive one month periods of M (2550 mg/day) or P. At the end of the two-weeks period CSII--initial P, the daily regular insulin requirement decreased significantly (40.1 +/- 18.1). During M and P body weight and HbA1 were unchanged (respectively 28.6 +/- 6.0 vs 29.0 +/- 59 kg/m2 and 7.7 +/- 1.1 vs 7.7 +/- 0.8%). With M daily insulin requirements decreased significantly (32.0 +/- 16.8 vs 38.4 +/- 18.2 IU, p less than 0.05). During test-meals, M compared to placebo also reduced peripheral free insulin concentrations (-24.9 +/- 26.0%) while plasma glucose and C peptide remained comparable. In the conditions of this study, combined CSII and M reduced the insulin resistance observed in overweighted insulin requiring diabetic patients.

    Certain types of implanted medical devices depend on oxygen supplied from surrounding tissues for their function. However, there is a concern that the tissue associated with the foreign body response to implants may become impermeable to oxygen over the long term and render the implant nonfunctional. We report oxygen flux recordings from electrochemical oxygen sensor devices with wireless telemetry implanted in subcutaneous porcine tissues. The devices remained implanted for up to 13 weeks and were removed with adjacent tissues at specified times for histologic examination. There are four main observations: (1) In the first few weeks after implantation, the oxygen flux to the sensors, or current density, declined to a sustained mean value, having unsynchronized cyclic variations around the mean; (2) The oxygen mass transfer resistance of the sensor membrane was negligible compared to that of the tissue, allowing for a sensitive estimate of the tissue permeability; (3) The effective diffusion coefficient of oxygen in tissues was found to be approximately one order of magnitude lower than in water; and (4) Quantitative histologic analysis of the tissues showed a mild foreign body response to the PDMS sensor membrane material, with capillaries positioned close to the implant surface. Continuous recordings of oxygen flux indicate that the tissue permeability changes predictably with time, and suggest that oxygen delivery can be sustained over the long term.

    The licensed live, attenuated varicella-zoster virus vaccine prevents herpes zoster in adults older than 50 years. We aimed to determine whether intradermal administration of zoster vaccine could enhance vaccine immunogenicity compared with conventional needle subcutaneous administration. In this randomised, dose-ranging study, adults aged 50 years or older who had a history of varicella or who had resided in a country with endemic varicella-zoster virus infection for 30 years or more were eligible. Participants received the approved full or a 1/3 dose of zoster vaccine given subcutaneously or one of four intradermal doses (full, 1/3, 1/10, or 1/27 dose) using the MicronJet600 device. The two subcutaneous doses and the four intradermal doses were randomised (1·5:1:1:1:1:1) by computer generated sequence with randomisation stratified by age (50-59 years or 60 years or older). The primary immunogenicity endpoint was the change from baseline in IgG antibody to varicella-zoster virus-specific glycoproteins (gpELISA) measured at 6 weeks. All patients were included in the primary and safety analyses. This study is registered with ClinicalTrials.gov, number NCT01385566. Between Sept 2, 2011, and Jan 13, 2012, 224 participants were enrolled from three clinics in the USA and 223 were randomly assigned: 52 to receive the full dose subcutaneous zoster vaccine, 34 to receive the 1/3 dose subcutaneous zoster vaccine, 34 to receive the full dose intradermal zoster vaccine, 35 to receive the 1/3 dose intradermal zoster vaccine, 34 to receive the 1/10 dose intradermal zoster vaccine, and 34 to receive the 1/27 dose intradermal zoster vaccine. Full dose zoster vaccine given subcutaneously resulted in a gpELISA geometric mean fold-rise (GMFR) of 1·74 (90% CI 1·48-2·04) at 6 weeks post-vaccination compared with intradermal administration which resulted in a significantly higher gpELISA GMFR of 3·25 (2·68-3·94; pvaricella-zoster virus gpELISA antibody compared with subcutaneous

    The ATLAS Overview Weeks always provide a good opportunity to see the status and progress throughout the experiment, and the July week at Glasgow University was no exception. The setting, amidst the traditional buildings of one of the UK's oldest universities, provided a nice counterpoint to all the cutting-edge research and technology being discussed. And despite predictions to the contrary, the weather at these northern latitudes was actually a great improvement on the previous few weeks in Geneva. The meeting sessions comprehensively covered the whole ATLAS project, from the subdetector and TDAQ systems and their commissioning, through to offline computing, analysis and physics. As a long-time ATLAS member who remembers plenary meetings in 1991 with 30 people drawing detector layouts on a whiteboard, the hardware and installation sessions were particularly impressive - to see how these dreams have been translated into 7000 tons of reality (and with attendant cabling, supports and services, which certainly...

    We report a case of spontaneous vertebral artery dissection (VAD) in a patient who developed extensive subcutaneous emphysema following the removal of a chest tube after a cardiac transplant. The pathophysiology and management of this uncommon complication are reviewed. Although vertebral and carotid artery dissections are unusual events occurring in 2.5 to 3 per 100,000 people, they are increasingly acknowledged to be important causes of stroke in the young and middle-aged adult population accounting for up to 25% of such cases. VADs are associated with a variety of minor traumatic mechanisms including painting a ceiling, yoga, chiropractic manipulation of the spine, and driving. These events cause injury to the vessel wall either by shearing forces secondary to rotational injuries or direct trauma to the vessel wall on bony prominences, especially the transverse processes of the cervical vertebrae. We present a case of a patient with documented previously normal vertebral arterial anatomy who developed a VAD after mediastinal tube removal resulted in subcutaneous emphysema tracking through fascial planes into his neck. © 2010 Wiley Periodicals, Inc.

    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.

    A novel 3D reconstruction and fast imaging system for subcutaneous veins by augmented reality is presented. The study was performed to reduce the failure rate and time required in intravenous injection by providing augmented vein structures that back-project superimposed veins on the skin surface of the hand. Images of the subcutaneous vein are captured by two industrial cameras with extra reflective near-infrared lights. The veins are then segmented by a multiple-feature clustering method. Vein structures captured by the two cameras are matched and reconstructed based on the epipolar constraint and homographic property. The skin surface is reconstructed by active structured light with spatial encoding values and fusion displayed with the reconstructed vein. The vein and skin surface are both reconstructed in the 3D space. Results show that the structures can be precisely back-projected to the back of the hand for further augmented display and visualization. The overall system performance is evaluated in terms of vein segmentation, accuracy of vein matching, feature points distance error, duration times, accuracy of skin reconstruction, and augmented display. All experiments are validated with sets of real vein data. The imaging and augmented system produces good imaging and augmented reality results with high speed.

  7. Pneumomediastinum, pneumothorax and subcutaneous emphysema complicating MIS herniorrhaphy.

    PURPOSE: Videoscopic herniorrhaphy is being performed more frequently with advantages claimed over the conventional open approach. This clinical report describes a pneumothorax, pneumomediastinum and subcutaneous emphysema occurring at the end of an extraperitoneal videoscopic herniorrhaphy. CLINICAL FEATURES: A 25 yr old ASA I man presented for elective extraperitoneal videoscopic hernia repair. Following intravenous induction with fentanyl, midazolam and propofol a balanced anesthetic technique using enflurane in N2O and O2 was used. Apart from a prolonged operating time (195 min), the procedure and anesthetic was uneventful. At the conclusion of the operation, prior to reversal of neuromuscular blockade extensive subcutaneous emphysema was noted on removal of the surgical drapes. Chest radiography revealed a pneumomediastinum and pneumothorax. A 25 FG intercostal tube was inserted and connected to an underwater seal drain. Sedation and positive pressure ventilation was maintained overnight to permit resolution and avoid airway compromise. The clinical and radiological features had resolved by the next morning and the patient\\'s trachea was extubated. His subsequent recovery was uneventful. CONCLUSION: Pneumothorax and pneumomediastinum are well recognised complications of laparoscopic techniques but have not been described following extraperitoneal herniorrhaphy. In this report we postulate possible mechanisms which may have contributed to their development, including inadvertent breach of the peritoneum and leakage of gas around the diaphragmatic herniae or tracking of gas retroperitoneally. The case alerts us to the possibility of this complication occurring in patients undergoing videoscopic herniorrhaphy.

    CONTEXT. Although neurological toxicity from elemental mercury vapor and organic mercury exposure has been commonly reported in the literature, it is rarely reported from soft tissue injection of elemental mercury. We present a case of neurological dysfunction from subcutaneous injection of elemental mercury. CASE DETAILS. A 35-year-old Latin American man subacutely developed gait ataxia, diplopia, and vomiting 1 year after subcutaneous injection of elemental mercury, a practice common in Afro-Caribbean and Latin-American cultures. Physical examination showed an indurated plaque on his right shoulder at the injection site, left third nerve and bilateral sixth nerve palsies, nystagmus, dysarthria, and gait and limb ataxia. The patient's serum and 24-h urine mercury levels were significantly elevated; he underwent excision of the mercury reservoir and chelation with dimercaptosuccinic acid but experienced only mild improvement after 1 year. DISCUSSION. Neurological sequelae from elemental mercury, specifically cognitive dysfunction, tremor, cortical myoclonus, and peripheral neuropathy, have been reported but cranial neuropathies, ataxia, cerebrospinal fluid pleocytosis, and the presence of anti-Purkinje cell type-Tr antibody have not. Treatment involves removal of any existing mercury reservoir and chelation; however, improvement in neurological dysfunction after treatment has rarely been reported in the literature.

  9. Subcutaneous Implants of Buprenorphine-Cholesterol-Triglyceride Powder in Mice

    Full Text Available Subcutaneous drug implants are convenient systems for the long-term delivery of drugs in animals. Lipid carriers are logical tools because they generally allow for higher doses and low toxicity. The present study used an US Food and Drug Administration Target Animal Safety test system to evaluate the safety of a subcutaneous implant of a cholesterol-triglyceride-buprenorphine powder in 120 BALB/c mice. Mice were evaluated in 4- and 12-day trials with 1- and 5-fold doses of the intended 3 mg/kg dose of drug. One male mouse treated with three 3 mg/kg doses and surgery on days 0, 4, and 8 died on day 9. The cause of death was not determined. In the surviving 119 mice there was no evidence of skin reaction at the site of the implant. Compared to control animals treated with saline, weight measurements, clinical pathology, histopathology, and clinical observations were unremarkable. These results demonstrate that the lipid carrier is substantially safe. Cholesterol-triglyceride-drug powders may provide a valuable research tool for studies of analgesic and inflammatory drug implants in veterinary medicine.

    The efficacy and side effects of subcutaneous epinephrine (E) and aerosolized metaproterenol (M) were compared in acute asthma. Adults randomly received E 0.3 mg sub-Q q20min (max 0.9 mg; n = 20) or M 15 mg in 3.0 ml NaCl 0.9% nebulized over 10 minutes (n = 20) in a double-blind fashion. Vital signs and peak expiratory flow rate (PEFR) were measured every ten minutes for one hour. The two groups were comparable in age, weight, baseline theophylline concentration, PEFR, heart rate, and systolic and diastolic blood pressure. PEFR improved in both groups within ten minutes (p less than 0.01; analysis of variance). There was no difference in PEFR between the groups over the one-hour observation period following treatment. Heart rate decreased following treatment in M patients (p less than 0.05), but remained unchanged in E patients. Systolic blood pressure rose slightly in E patients (p less than 0.01), but remained unchanged in M patients. Subcutaneous E and nebulized M are equally effective as initial therapy in acute asthma.

    Subcutaneous emphysema occurs when air is forced beneath the tissue, leading to swelling, crepitus on palpation and has the potential to spread along the fascial planes. This report describes the youngest case of subcutaneous emphysema related to dental treatment that has been documented to date. In addition to the patient's age, the case is of interest because periorbital subcutaneous emphysema is a rarest complication of stainless steel crown procedure.

    We compared two dosing schedules for subcutaneous injections of a low-dose humanized anti-CD20 antibody, veltuzumab, in immune thrombocytopenia. Fifty adults with primary immune thrombocytopenia, in whom one or more lines of standard therapy had failed and who had a platelet count <30×10(9)/L but no major bleeding, initially received escalating 80, 160, or 320 mg doses of subcutaneous veltuzumab administered twice, 2 weeks apart; the last group received once-weekly doses of 320 mg for 4 weeks. In all dose groups, injection reactions were transient and mild to moderate; there were no other safety issues. Forty-seven response-evaluable patients had 23 (49%) objective responses (platelet counts ≥30×10(9)/L and ≥2 × baseline) including 15 (32%) complete responses (platelets ≥100×10(9)/L). Responses (including complete responses) and bleeding reduction occurred in all dose groups and were not dose-dependent. In contrast, response duration increased progressively with total dose, reaching a median of 2.7 years with the four once-weekly 320-mg doses. Among nine responders retreated at relapse, three at higher dose levels responded again, including one patient who was retreated four times. In all dose groups, B-cell depletion occurred after the first dose until recovery starting 12 to 16 weeks after treatment. Veltuzumab serum levels increased with dose group according to total dose administered, but terminal half-life and clearance were comparable. Human anti-veltuzumab antibody titers developed without apparent dose dependence in nine patients, of whom six responded including five who had complete responses. Subcutaneous veltuzumab was convenient, well-tolerated, and active, without causing significant safety concerns. Platelet responses and bleeding reduction occurred in all dose groups, and response durability appeared to improve with higher doses. Clinicaltrials.gov identifier: NCT00547066.

    Administration into the subcutaneous (SC) tissue is a typical route of delivery for therapeutic proteins, especially for frequent treatments, long-term regimens, or self-administration. It is currently believed that the maximum volume for SC injections is approximately 1.5 mL. Larger SC injection volumes are considered to be associated with injection pain and adverse events at the injection site. However, no controlled clinical studies and actual evidence exist to support this assumption. In this review, we discuss current and publically available data related to SC administration volumes. We conclude that injection volumes higher than 3.5 mL are worth exploring if required for the development of efficacious drug treatments. Studying tissue back pressure, injection site leakage, local tolerability, and injection-related adverse events, such as injection pain, should be considered for the development of higher SC injection volumes.

  19. Subcutaneous blood flow in early male pattern baldness

    Energy Technology Data Exchange (ETDEWEB)

    Klemp, P.; Peters, K.; Hansted, B.

    1989-05-01

    The subcutaneous blood flow (SBF) was measured by the /sup 133/Xe washout method in the scalp of 14 patients with early male pattern baldness. Control experiments were performed in 14 normal haired men matched for age. The SBF in the scalp of the normal individuals was about 10 times higher than previously reported SBF values in other anatomical regions. In patients with early male pattern baldness, SBF was 2.6 times lower than the values found in the normal individuals (13.7 +/- 9.6 vs 35.7 +/- 10.5 ml/100 g/min-1). This difference was statistically significant (p much less than 0.001). A reduced nutritive blood flow to the hair follicles might be a significant event in the pathogenesis of early male pattern baldness.

    OBJECTIVE: 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. DESIGN: 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. METHODS: Central fat mass (CFM) and lower extremity fat mass (LEFM) were measured by dual X-ray absorptiometry. Subcutaneous abdominal adipose tissue (SAT...

  1. Subcutaneous and Sublingual Immunotherapy in Allergic Asthma in Children

    Directory of Open Access Journals (Sweden)

    Sophia Tsabouri

    2017-04-01

    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.

    Bost, Wolfgang; Lemor, Robert; Fournelle, Marc

    2014-09-01

    We developed a combined imaging platform allowing optoacoustic and ultrasound imaging based on a low energy laser and a handheld probe. The device is based on a sensitive single element 35-MHz focused transducer, a 2-D piezoscanner and a dual-wavelength switchable Nd:YAG laser. Acoustical detection and optical illumination are confocal for optimization of optoacoustic signal-to-noise ratio. The system allows to scan over a range up to 12 mm ×12 mm in xy-direction with an isotropic lateral resolution of about 90 μm. Although the device is a class 1 laser product having pulse energies in the range, in vivo images of subcutaneous microvasculature could be obtained from human skin with signal-to-noise levels as good as 20 dB.

    Full Text Available A mass in right supraclavicular fossa in a diabetic patient mimicking tuberculosis (TB adenitis that ultimately proved to be subcutaneous zygomycosis. A high degree of clinical suspicion is needed for diagnosis especially when these lesions occur at typical sites for the more common indolent infections like TB. This case is being presented not only because of its rarity, but to emphasize the role of early diagnosis and appropriate treatment to prevent serious complications due to proximity to major structures. Fluconazole was used despite not being the ideal drug, solely due to cost constraints. Our patient responded well. However, we do emphasize that response to fluconazole is the exception rather than the rule.

    Fine-needle aspiration of subcutaneous fat (FNAF) was performed in 24 patients, 12 with previously diagnosed amyloidosis presenting with proteinuria or nephrotic syndrome, and 12 presenting a nephrotic syndrome without amyloidosis on renal biopsy. FNAF was positive in 10 of 12 patients with amyloidosis (sensitivity: 83%) and negative in 12 of 12 patients with non-amyloid nephrotic syndrome (specificity: 100%). Considering a 2.5 to 10% prevalence of amyloidosis in adult patients with proteinuria or nephrotic syndrome, a positive FNAF is diagnostic of amyloidosis, and a negative FNAF rules out the diagnosis with a probability of 98 to 99%. FNAF is a simple and safe method which can be useful in patients who cannot undergo a renal biopsy.

  5. Subcutaneous Fluid Administration: A Potentially Useful Tool in Prehospital Care

    Full Text Available Mass casualty incidents (MCIs and disaster medical situations are ideal settings in which there is need for a novel approach to infusing fluids and medications into a patient’s intravascular space. An attractive new approach would avoid the potentially time-consuming needlestick and venous cannulation requiring a trained practitioner. In multiple-patient situations, trained practitioners are not always available in sufficient numbers to enable timely placement of intravenous catheters. The novel approach for intravascular space infusion, described in this paper involves the preadministration of the enzyme, human recombinant hyaluronidase (HRH, into the subcutaneous (SC space, via an indwelling catheter. The enzyme “loosens” the SC space effectively enhancing the absorption of fluids and medication.

  6. ATLAS Overview Week at Brookhaven

    CERN Multimedia

    Pilcher, J

    Over 200 ATLAS participants gathered at Brookhaven National Laboratory during the first week of June for our annual overview week. Some system communities arrived early and held meetings on Saturday and Sunday, and the detector interface group (DIG) and Technical Coordination also took advantage of the time to discuss issues of interest for all detector systems. Sunday was also marked by a workshop on the possibilities for heavy ion physics with ATLAS. Beginning on Monday, and for the rest of the week, sessions were held in common in the well equipped Berkner Hall auditorium complex. Laptop computers became the norm for presentations and a wireless network kept laptop owners well connected. Most lunches and dinners were held on the lawn outside Berkner Hall. The weather was very cooperative and it was an extremely pleasant setting. This picture shows most of the participants from a view on the roof of Berkner Hall. Technical Coordination and Integration issues started the reports on Monday and became a...

    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.

    Injection of local anaesthetics is an uncomfortable procedure. The purpose of this study was to determine the influence of lidocaine temperature on pain during subcutaneous injection. A randomised, double blind trial with 36 healthy volunteers was performed. Each subject received three injections of 4.5 ml 1% lidocaine subcutaneously on the abdomen; refrigerated (8 °C), at room temperature (21 °C), and warmed to body temperature (37 °C). By giving every subject injections of all three temperatures they served as their own controls. The participants were asked to evaluate the pain felt during the injection by placing a pencil mark on a 100 mm Visual Analogue Scale without intermediate markings immediately after every injection. They were told that the scale ranged from no pain to worst imaginable pain (0 = best; 100 = worst). Retrospectively the participants did a verbal assessment of the most and least painful injection. The median VAS score for the heated lidocaine was 16 (range =11-28), lidocaine at room temperature 25 (13-40) and for the cold 24 (11-35). The VAS scores for the heated lidocaine was significantly lower than for lidocaine at room temperature (p = 0.004). Also, the verbal assessment of heated lidocaine being less painful than the injection at room temperature was statistically significant (p = 0.015). Injection with lidocaine heated to around body temperature was less painful than injection with lidocaine at room temperature. There was no statistically significant difference in verbal assessment or VAS scores between the cold lidocaine and that at room temperature.

    The noninferiority of a 6-week dosing schedule of lanreotide Autogel (Lan ATG) at a dose of 120 mg compared with a 3-week dosing schedule of lanreotide microparticles (Lan MP) at a dose of 60 mg was investigated in patients with neuroendocrine tumors (NET). Patients who had sporadic, well differentiated NET with a low grade of malignancy were recruited for this open-label, Phase III, multicenter trial. Patients were randomized to receive either 3 deep subcutaneous injections of Lan ATG (120 mg, every 6 weeks) or 6 intramuscular injections of Lan MP (60 mg, every 3 weeks). Tumor markers, tumor size, and symptoms were assessed between baseline and Week 18. Success was classified as a response that ranged from disappearance to an increase <25% in tumor marker, tumor size, or symptom frequency. Sixty patients were randomized, and 46 patients completed the study. Both for tumor markers and for tumor size, Lan ATG was not inferior to Lan MP (55% and 59% of patients responded on tumor markers, respectively; 68% and 66% of patients responded on tumor size, respectively). There were too few symptomatic patients to compare carcinoid symptoms. Both treatments were tolerated well, and no safety concerns were identified. Lan ATG at a dose of 120 mg every 6 weeks was as effective for controlling NET as Lan MP at a dose of 60 mg every 3 weeks.

    We report a case of a 27-year-old Japanese female with Sjogren's syndrome (SS), who suffered from several episodes of subcutaneous and mesenteric panniculitis with a recurrence within one year. After a history of fever and skin rash, the patient underwent surgery at a local hospital with a diagnosis of acute appendicitis complicated with an ileocecal abscess. She was also diagnosed as having SS. After the operation, the fever and skin rash persisted. She was treated with prednisolone (PSL), and her symptoms resolved. A recurrent bout of abdominal pain with fever, annular erythema on the trunk and a nodular erythematous rash on the lower extremities occurred six months after the operation. A skin biopsy from the lower extremities showed findings that were compatible with panniculitis. Abdominal computer tomography (CT) showed a diffuse swelling with soft tissue density in the intestinal mesenterium and para aortic area. A retrospective examination of the operative specimen obtained from the local hospital revealed centrilobular infiltration of neutrophils in the mesenteric adipose tissue with fat necrosis, which is compatible with mesenteric panniculitis. Twenty mg/day of PSL was successful in treating the systemic panniculitis, and the abnormal diffuse soft tissue density on the abdominal CT disappeared after three weeks of PSL administration. Systemic panniculitis is a rare complication in SS, and the pathogenesis is unclear.

    Full Text Available John D CarmichaelDepartment of Medicine, Cedars-Sinai Medical Center, Los Angeles, CA, USAAbstract: Acromegaly is a rare disease characterized by excessive growth hormone secretion, usually from a pituitary tumor. Treatment options include surgery, medical therapy, and in some cases, radiation therapy. Current medical therapy consists of treatment with somatostatin analog medications or a growth hormone receptor antagonist. There are two somatostatin analogs currently in use, octreotide and lanreotide. Both are supplied in long-acting formulations and are of comparable biochemical efficacy. Lanreotide is supplied in a prefilled syringe and is injected into deep subcutaneous tissue. Studies have been conducted to assess the efficacy of self- or partner administration, and have demonstrated that injection of lanreotide can be accomplished reliably and safely outside a physician's office. For patients who have achieved biochemical control with lanreotide, the FDA has recently approved an extended dosing interval. Selected patients may be able to receive the medication less frequently with injections of 120 mg administered every 6 or 8 weeks. This review focuses on the use of lanreotide in the treatment of acromegaly, the safety and efficacy of the drug, and the benefits afforded to patients because of unique aspects of the delivery of lanreotide.Keywords: acromegaly, treatment, lanreotide, somatostatin analog, pituitary tumor

    Objective: The objective was to assess the amount of vitamin D-3 stored in adipose tissue after long-term supplementation with high dose vitamin D-3. Design: A cross-sectional study on 29 subjects with impaired glucose tolerance who had participated in a randomized controlled trial with vitamin D-3...... 20 000 IU (500 mu g) per week vs placebo for 3-5 years. Methods: Abdominal subcutaneous fat tissue was obtained by needle biopsy for the measurements of vitamin D-3 and 25-hydroxyvitamin D-3 (25(OH)D-3). Body fat was measured with dual-energy X-ray absorptiometry, and serum 25(OH)D-3 level...... was quantified. Results: In the subjects given vitamin D-3, the median concentrations of serum 25(OH)D-3, fat vitamin D-3, and fat 25(OH)D-3 were 99 nmol/l, 209 ng/g, and 3.8 ng/g, respectively; and correspondingly in the placebo group 62 nmol/l, 32 ng/g, and 2.5 ng/g.

    2017-03-01

    Full Text Available Objective: Dirofilariasis is a parasitic infection caused by filarial nematodes belonging to the genus Dirofilaria . Human dirofilariasis due to Dirofilaria repens has been widely reported from European countries. Sri Lanka is the most affected country in Asia with an infection rate of almost 60% in dog population. However, human infection of D. repens remains undiagnosed and many of the cases are not scientifically documented. Therefore, the objective of the present investigation is to document the presence of dirofilariasis infections in humans. Method: A 1 year and 10 months old boy from Ragama, Gampaha District, Western Province of Sri Lanka, was presented to a private hospital with a painless, non-pruritic and ill-defined subcutaneous nodule on his right hypochondrial region of the anterior abdominal wall for 1 week. On examination, there was a non-tender swelling measuring 2 cm × 2 cm in the anterior abdominal wall, with surrounding mild redness. The patient was referred for ultrasound confirmation. Results: The ultrasound scan revealed a hypoechoic nodular lesion measuring 11 mm × 6 mm in the anterior abdominal wall. Parasitological examination on the excised nodule confirmed the presence of D. repens measuring 10.5 cm in length having characteristic cuticle with longitudinal ridges. Conclusion: It is essential to record the human infections and increase the awareness about this infection, diagnostic tests and vector controlling measures, in order to reduce the disease prevalence through suppressing vector densities, proper diagnosis and patient care.

    Naturally contaminated beef-brisket fat showed a psychrotroph count of 4 × 10(9) CFU/cm(2) after 14 days of aerobic refrigerated storage (5°C ± 1°C). Pseudomonas was the predominating genus. Other micro-organisms, such as Enterobacteriaceae and Brochothrix thermosphacta, grew up to 2·5 × 10(8) cfu/cm(2) and 1·6 × 10(8) cfu/cm(2), respectively. Concentrations of different substrates that could support microbial growth were measured. Glucose concentration dropped to approximately one-third of the initial level during the first week of storage. Lactic acid also declined. Free fatty acids increased significantly (P < 0·05) during refrigeration. However, other lipid-deterioration indices, such as the thiobarbituric acid number and the peroxide value, remained unchanged. Beef subcutaneous fat had a high initial microbial load and a capacity to support extensive bacterial growth. It may therefore constitute an important source of contamination for meat and manufactured meat products.

    2017-05-01

    Diabetes mellitus (DM) is a metabolic disorder due to irregularities in glucose metabolism, as a result of insulin disregulation. Chronic DM (Type 1) is treated by daily insulin injections by subcutaneous route. Daily injections cause serious patient non-compliance and medication non-adherence. Insulin Depots (ID) are parenteral formulations designed to release the insulin over a specified period of time, to control the plasma blood glucose level for intended duration. Physiologically, pancreas produces and secretes insulin in basal and pulsatile mode into the blood. Delivery systems mimicking basal release profiles are known as open-loop systems and current marketed products are open-loop systems. Future trend in open-loop systems is to reduce the number of injections per week by enhancing duration of action, by modifying the depot properties. The next generation technologies are closed-loop systems that mimic the pulsatile mode of delivery by pancreas. In closed-loop systems insulin will be released in response to plasma glucose. This review focuses on future trend in open-loop systems; by understanding (a) the secretion of insulin from pancreas, (b) the insulin regulation normal and in DM, (c) insulin depots and (d) the recent progress in open-loop depot technology particularly with respect to nanosystems.

    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.

    To evaluate the combined effects of CpG oligodeoxynucleotides (CpG-ODNs) adjuvant and subcutaneous injection route on efficacy of a HIV-1-tat DNA vaccine candidate using BALB/c mice as an animal model. Evaluation of cellular and humoral immunity of mice injected subcutaneously with HIV-1-tat gene cloned into a pcDNA3.1 vector indicated that significant levels of IFN-γ cytokine secretion (900 pg/ml), lymphocyte proliferation (2.5 stimulation index) and IgG2a (1.45 absorbance 450 nm) production could be achieved. These indicators of stimulated cellular immunity were elicited 2 weeks after the last injection (P < 0.05). Formulation of HIV-1-tat DNA vaccine candidate with CpG-ODNs as an adjuvant while administrated subcutaneously are a promising approach to induce effective cellular immunity responses against HIV-1 infection.

    Nicola Scichilone

    2009-01-01

    Full Text Available We describe the case of an adolescent who was admitted to the hospital because of sudden occurrence of chest pain, dyspnea and subcutaneous emphysema. On admission, physical examination revealed subcutaneous crepitations in the superior part of the rib cage, and auscultation of the chest showed widespread wheezing. The radiological assessment confirmed the diagnosis of pneumomediastinum and pneumothorax. A follow-up CT scan performed one week after the admission showed almost complete resolution of the radiological alterations. At the following visits, the patient was asymptomatic, but reported to have suffered from frequent episodes of rhinorrea, sneezing, nasal blockage, and sometimes, chest tightness, especially during exposure to pets and/or windy weather. Skin prick testing showed sensitivities to dermatophagoides pteronyssinus and farinae, grass pollen and dog dander. Spirometry documented significant improvement in lung function after short-acting bronchodilator, allowing for the diagnosis of asthma to be made. Although pneumomediastinum may be a complication of various respiratory diseases, including asthma, it has never been reported as the first presentation of underlying bronchial asthma. Herein, the physiopathological mechanisms, the diagnostic procedures and treatment of pneumomediastinum in asthma are discussed. We suggest that the diagnosis of asthma should be considered in the differential diagnosis of pneumomediastinum in adolescence.

    The aim of this study was to examine the fate of differently sized protein aggregates upon subcutaneous injection in mice. A murine and a human monoclonal immunoglobulin G 1 (IgG1) antibody were labeled with a fluorescent dye and subjected to stress conditions to create aggregates. Aggregates fractionated by centrifugation or gel permeation chromatography were administered subcutaneously into SKH1 mice. The biodistribution was measured by in vivo fluorescence imaging for up to 1 week post injection. At several time points, mice were sacrificed and selected organs and tissues were collected for ex vivo analysis. Part of injected aggregated IgGs persisted much longer at the injection site than unstressed controls. Aggregate fractions containing submicron (0.1-1 μm) or micron (1-100 μm) particles were retained to a similar extent. Highly fluorescent "hot-spots" were detected 24 h post injection in spleens of mice injected with submicron aggregates of murine IgG. Submicron aggregates of human IgG showed higher accumulation in draining lymph nodes 1 h post injection than unstressed controls or micron size aggregates. For both tested proteins, aggregated fractions seemed to be eliminated from circulation more rapidly than monomeric fractions. The biodistribution of monomers isolated from solutions subjected to stress conditions was similar to that of unstressed control. Copyright © 2016 American Pharmacists Association®.

    2015-01-01

    Full Text Available Subcutaneous emphysema is a known complication of carbon dioxide insufflation, an essential component of laparoscopy. The literature contains reports of hypercarbia, pneumothorax, or pneumomediastinum. However, isolated lower extremity subcutaneous emphysema remains a seldom-reported complication. We report a case of unilateral lower extremity subcutaneous emphysema following robotic-assisted hysterectomy, bilateral salpingooophorectomy, staging, and anterior/posterior colporrhaphy for carcinosarcoma and vaginal prolapse. On postoperative day 1, the patient developed tender crepitus and bruising of her right ankle. Radiography confirmed presence of subcutaneous air. Vital signs and laboratory findings were unremarkable. Her symptoms spontaneously improved over time, and she was discharged in good condition on day 2. In stable patients with postoperative extremity swelling or pain with crepitus on exam, the diagnosis of iatrogenic subcutaneous emphysema must be considered.

    Full Text Available Pneumomediastinum, and subcutaneous emphysema usually result from spontaneous alveolar wall rupture and, far less commonly, from disruption of the upper airways or gastrointestinal tract. Subcutaneous neck emphysema, pneumomediastinum, and retropneumoperitoneum caused by nontraumatic perforations of the colon have been infrequently reported. The main symptoms of spontaneous subcutaneous emphysema are swelling and crepitus over the involved site; further clinical findings in case of subcutaneous cervical and mediastinal emphysema can be neck and chest pain and dyspnea. Radiological imaging plays an important role to achieve the correct diagnosis and extension of the disease. We present a quite rare case of spontaneous subcutaneous cervical emphysema, pneumomediastinum, and pneumoretroperitoneum due to perforation of an occult sigmoid diverticulum. Abdomen ultrasound, chest X-rays, and computer tomography (CT were performed to evaluate the free gas extension and to identify potential sources of extravasating gas. Radiological diagnosis was confirmed by the subsequent surgical exploration.

    Full Text Available History of present illness: 63-year-old male with a history of diabetes mellitus and rheumatoid arthritis who was sent to the emergency department by his primary care provider for further evaluation of left upper extremity crepitus. The patient fell onto his left elbow two days prior to presentation resulting in immediate swelling and a small laceration. He complained of minimal pain and denied fevers or chills. His medications included metformin, tocilizumab, methotrexate and prednisone. In the ED, the patient was well-appearing, afebrile, with a normal heart rate and in no acute distress. Examination of the left upper extremity revealed no tenderness to palpation but marked crepitus with a scabbed laceration over his olecranon process and was neurovascularly intact. White blood cell count (WBC, sodium, glucose, inflammatory markers and lactate were all within normal limits. Significant findings: X-Rays of the elbow revealed diffuse striated lucencies throughout the soft tissue, consistent with extensive subcutaneous air throughout the superficial and deep tissues. There was no evidence of a fracture. Discussion: The initiating mechanism for necrotizing soft tissue infections (NSTIs is a disruption of the fascial planes, most commonly by trauma. The inoculated bacteria rapidly spread and surgical debridement is necessary.1-3 Early recognition and disposition to the operating room in 51 are correlated with increased morbidity and mortality.5 Additionally, it has been found that immunocompromised patients exhibit atypical presentations of NSTIs.6 The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC score is often used to risk stratify patients when there is suspicion for an NSTI.7 The patient discussed here had a LRINEC score of 0. However, the physical exam finding of crepitus, coupled with his history of immunocompromised status and subcutaneous air on X-ray made the diagnosis of NSTI seem likely. However, upon surgical exploration

    Administering monosodium glutamate (MSG) to neonatal rodents induces obesity and type 2 diabetes. In addition, several studies have shown that MSG administered to pregnant animals can cross the placenta and reach the foetus. The present study was performed to investigate the effects of administering MSG to pregnant ICR mice on dam and neonatal growth. Pregnant mice were treated with 60 or 120 mg MSG once daily from day 5 of pregnancy to one day before parturition by subcutaneous injection. In addition, the body weights of the neonates were determined until nine weeks of age. The birth weights of neonates were not different between the control and MSG-treated groups. However, MSG treatment resulted in a lower body weight gain of neonates during lactation. In addition, this underweight of the MSG-treated group at weaning returned to normal compared with the control group at five weeks of age. Cross-fostering experiments indicated that the lower body weight gain of neonates in the MSG-treated group during lactation was due to its effects on the dam. Serum prolactin levels and mammary gland development of the mice were examined next to determine the reasons for this lactation problem. Although there were no differences in prolactin levels, morphological analyses of the mammary glands revealed apparent differences, including low numbers and altered phenotype of alveoli, between the control and MSG-treated groups. Taken together, our results show that treating pregnant mice with excess MSG induced lower neonate body weight gain during lactation. © The Author(s) 2015.

    Although oral methotrexate is an effective first-line traditional systemic therapy for psoriasis, the use of the subcutaneous form of methotrexate for the treatment of psoriasis has not been fully established. 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. Systematic literature searches were conducted of the PubMed, Ovid, and ClinicalTrials.gov databases. 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. 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, its application for the treatment of moderate-to-severe psoriasis is promising. More evidence-based studies on psoriasis subjects are needed to explore the practical application of subcutaneous methotrexate as a treatment option for severe recalcitrant psoriasis.

    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.

    2014-01-01

    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.

    A retained medullary cord (RMC) is a rare closed spinal dysraphism with a robust elongated neural structure continuous from the conus and extending to the dural cul-de-sac. One case extending down to the base of a subcutaneous meningocele at the sacral level has been reported. We report on three cases of closed spinal dysraphism, in which a spinal cord-like tethering structure extended out from the dural cul-de-sac and terminated at a skin-covered meningocele sac in the sacrococcygeal region, which was well delineated in curvilinear coronal reconstructed images of 3D-heavily T2-weighted images (3D-hT2WI). Intraoperative neurophysiology revealed the spinal cord-like tethering structure was nonfunctional, and histopathology showed that it consisted of central nervous system tissue, consistent with RMC. The tethering structure histologically contained a glioneuronal core with an ependymal-like lumen and smooth muscle, which may indicate developmental failure during secondary neurulation. When the RMC extending to a meningocele is demonstrated with the detailed magnet resonance imaging including 3D-hT2WI, decision to cut the cord-like structure for untethering of the nervous tissue should be made under careful intraoperative neurophysiological monitoring.

    Biodentine (Septodont, St-Maur-des-Fossés, France) is a new material suitable for various clinical situations in endodontics, such as perforation repair, retrograde filling, pulp capping, and others. Because it is a new material, its properties should be analyzed before routine clinical use. Thus, this study evaluated the biocompatibility of Biodentine in the subcutaneous tissue of rats. This study was conducted on 15 male rats. Two incisions were made on the dorsal region of each animal for the introduction of 4 tubes. One tube was empty, 1 was filled with zinc oxide-eugenol cement, 1 was filled with mineral trioxide aggregate, and the last tube was filled with Biodentine. After 7, 14, and 30 days, the animals were sacrificed, and the specimens were submitted to histotechnical preparation. The histologic sections were stained with hematoxylin-eosin and analyzed using light microscopy. Scores were established according to the inflammatory process and were statistically compared using the Kruskal-Wallis test (P Biodentine; however, at 14 and 30 days, the inflammatory process was mild or nonsignificant. Biodentine was biocompatible with tissue after the 14th day. Copyright © 2014 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    Full Text Available Aim. Continuous subcutaneous insulin infusion (CSII is used as an option in patients with diabetes failing to multiple daily injections (MDI. Psychological factors may play a relevant role in the failure to attain therapeutic goals in patients on MDI. This could lead to an overrepresentation of psychopathology in patients treated with CSII. Methods. A consecutive series of 100 patients with type 1 diabetes was studied, collecting main clinical parameters and assessing psychopathology with the self-reported questionnaire Symptom Checklist 90-revised. Patients on CSII were then compared with those on MDI. Results. Of the 100 enrolled patients, 44 and 56 were on CSII and MDI, respectively. Among men, those on CSII were younger than those on MDI; conversely, no difference in age was observed in women. Women on CSII showed higher scores on most Symptom Checklist 90 subscales than those on MDI, whereas no differences were observed in men. Conclusion. Women with type 1 diabetes treated with CSII display higher levels of psychopathology than those on MDI. This is probably the consequence of the fact that patients selected for CSII are those failing to MDI. Higher levels of psychopathology could represent a limit for the attainment and maintenance of therapeutic goals with CSII.

    Obesity is associated with the development of metabolic complications such as insulin resistance (IR). The mechanisms leading to IR remain unclear. This study aimed to investigate the relationship between adipose tissue fibrosis and IR in obese patients before and after bariatric surgery. Thirty-five obese patients awaiting bariatric surgery (12 with type 2 diabetes) were included in the study. Non-diabetic patients were classified as either insulin-sensitive (n=11) or insulin-resistant (n=12), based on the Matsuda insulin sensitivity index (ISI Matsuda ). Homoeostasis model assessment (HOMA-IR) was used for longitudinal evaluation of insulin resistance. Fibrosis was quantified by Masson's trichrome staining on microscopy, and mRNA levels of fibrosis-related genes were examined in subcutaneous (SAT) and visceral adipose tissue (VAT) biopsies collected during and 6 months after bariatric surgery (SAT only). Despite their similar age, body mass index and fat mass, SAT fibrosis was significantly higher in diabetic vs insulin-sensitive patients (Psurgery and significant weight loss, fibrosis levels remained unchanged in SAT, although IR was significantly reduced in all groups (Psurgery. Overall, these results show a significant but, most likely, transient association between SAT fibrosis and IR in obese humans. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    To compare the relative bioavailability, safety and tolerability of oral methotrexate (MTX) and subcutaneous (SC) MTX administered via an auto-injector (MTXAI) in patients with rheumatoid arthritis (RA). In this randomised, multicenter, open-label, three-way crossover study, patients ≥18 years with adult RA undergoing treatment with MTX for ≥3 months were assigned to receive MTX 10, 15, 20 and 25 mg weekly in a random sequence of three treatments: oral, SC into the abdomen and SC into the thigh. For 24 h after administration of each treatment, blood samples were collected for pharmacokinetic analysis and injection sites were assessed. Forty-seven patients completed the study. Systemic exposure of oral MTX plateaued at doses ≥15 mg/week. In contrast, SC MTX demonstrated a linear increase in systemic exposure that was greater than oral MTX at each dose. No unexpected AEs were noted for either formulation. Unlike oral MTX, the systemic exposure of SC MTX did not plateau over the doses studied, particularly at doses ≥15 mg/week. In this study, higher systemic MTX exposure was not associated with increases in AEs. Patients with an inadequate clinical response to oral MTX may benefit from higher drug exposure by switching to SC MTX. NCT01618968. Published by the BMJ Publishing Group Limited.

    2012-01-01

    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

    This has been a busy week for the CERN Council, and there is much to report. Firstly, I’m pleased to say that Council approved the Organization’s Medium Term Plan, and with it the budget for financial year 2010. In a time of global recession, this is a strong vote of confidence from the Member States. This meeting of Council provided an opportunity for the working group on the scientific and geographical enlargement of CERN to set out a roadmap towards its final report, which is to be made at Council’s December session this year. One part of the process over the coming months is to bring the major players in particle physics from beyond the European region into the discussion, ensuring that the working group’s recommendations lead to an optimum position for CERN and European particle physics in the global context. An indicator of the continuing attractiveness of CERN is the fact that Council has received four new applications...

    It has been widely disseminated in the literature that subcutaneous packing, as part of mummification, was not usually done until the 21st dynasty. We aimed to study by computed tomography (CT) if subcutaneous packing was part of mummification of royal Egyptians dated to 18th to 20th dynasties. We analyzed the 2- and 3-dimensional CT images of 13 royal mummies dated to circa 1550 to 1153 BC for presence of subcutaneous embalming materials. Among the studied mummies were Amenhotep III, Tutankhamun, Seti I, and Ramesses II. We reported the CT characters of any detected subcutaneous embalming materials and noted their impact on the morphology of the involved body part. We correlated the CT findings with the archeological literature. Computed tomographic images showed subcutaneous packing in 12 (92.3%) mummies; whereas the mummy that was previously known as "Thutmose I" showed no such evidence. Subcutaneous packing involved the faces (n = 11), necks (n = 4), torsos (n = 5), and/or extremities (n = 4) of the mummies. Subcutaneous filling materials showed variation in homogeneity and CT densities and they were likely composed of resin, bits of linen with resin, or other substances. Subcutaneous packing procedure succeeded in providing uniform full contour of the involved body regions without causing significant tissue damages. Subcutaneous packing procedure was used as part of mummification of royal Ancient Egyptians dated to 18th to 20th dynasties earlier than what was believed in archaeology. The Ancient Egyptian embalmers must have been skilled in dissection and possessed surgical tools that enabled them to perform this fine procedure.

    2017-03-01

    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.

    Paragonimiasis is a parasitic disease caused by the lung fluke, Paragonimus spp. Lung flukes may be found in various organs, such as the brain, peritoneum, subcutaneous tissues, and retroperitoneum, other than the lungs. Abdominal paragonimiasis raises a considerable diagnostic challenge to clinicians, because it is uncommon and may be confused with other abdominopelvic inflammatory diseases, particularly peritoneal tuberculosis, and peritoneal carcinomatosis. Also, subcutaneous paragonimiasis does not easily bring up clinical suspicion, due to its rarity. We herein report 2 cases of abdominal paragonimiasis and 1 case of subcutaneous paragonimiasis in Korea.

    Full Text Available Granuloma annulare is a benign inflammatory dermatosis that is most common in children and young adults. The subcutaneous form of granuloma annulare, which occurs mainly on the extremities in children, is rare. Lesions usually occur as painless subcutaneous nodules without inflammation of the cutaneous surface; the most frequent sites are the legs, buttocks, and scalp. Nevertheless, we present a case of subcutaneous granuloma annulare confined to the dorsa of the hand joints and right knee in a 51-year-old woman.

    Full Text Available The entirely subcutaneous implantable cardioverter-defibrillator (ICD system was developed to provide a life-saving defibrillation therapy that does not affect the heart and vasculature. The subcutaneous ICD is preferred over the transvenous ICD for patients with a history of recurrent infection presenting major life-threatening rhythms. In this case report, we describe the first successful intermuscular implantation of a completely subcutaneous ICD in a Japanese patient with pectus excavatum. There were no associated complications with the device implantation or lead positioning. Further, the defibrillation threshold testing did not pose any problem with the abnormal anatomy of the patient.

    Full Text Available James P Simsarian, Carol Saunders, D Michelle SmithNeurology Center of Fairfax Ltd, Fairfax, VA, USABackground: Despite over 50 years of experience with adrenocorticotropic hormone (ACTH as a treatment for acute exacerbations of multiple sclerosis, there have been no trials examining the options of the 2–3-week dosing regimen or intramuscular injection protocol used in the original trials. At our clinic, we performed a small, prospective, randomized pilot study to examine the efficacy and safety of, and patient satisfaction with, a short (five-day self-administered ACTH dosing protocol for exacerbations of multiple sclerosis, and to compare the subcutaneous and intramuscular routes of administration.Methods: Patients for this study were recruited from an outpatient treatment clinic. Each patient self-administered natural ACTH gel 80 U/day by subcutaneous or intramuscular injection for five consecutive days and was evaluated at baseline and on days 7 and 14. Patient feedback was collected using the Patient Global Impression of Change (PGI-C, the primary efficacy measure, a patient global visual analog scale, the Expanded Disability Status Scale, a timed walk, the Nine-hole Peg Test, and the Clinical Global Impression of Change.Results: Of the 20 enrolled patients (mean age 39.5 years, 19 completed the study. On day 14, 61.1% of patients (11 of 18 with day 14 scores were treatment responders, and rated their condition as "very much improved" or "much improved" on the PGI-C. The intramuscular group had numerically more responders, but there was no significant difference in the proportion of responders between the intramuscular and subcutaneous groups at day 14 (P = 0.3. The intramuscular route of injection was associated with more injection site pain than the subcutaneous route.Conclusion: A shorter five-day course of intramuscular or subcutaneous ACTH gel may improve symptoms associated with acute exacerbations of multiple sclerosis.

    Valentin Barquissau

    2018-01-01

    Full Text Available Caloric restriction (CR is standard lifestyle therapy in obesity management. CR-induced weight loss improves the metabolic profile of individuals with obesity. In mice, occurrence of beige fat cells in white fat depots favors a metabolically healthy phenotype, and CR promotes browning of white adipose tissue (WAT. Here, human subcutaneous abdominal WAT samples were analyzed in 289 individuals with obesity following a two-phase dietary intervention consisting of an 8 week very low calorie diet and a 6-month weight-maintenance phase. Before the intervention, we show sex differences and seasonal variation, with higher expression of brown and beige markers in women with obesity and during winter, respectively. The very low calorie diet resulted in decreased browning of subcutaneous abdominal WAT. During the whole dietary intervention, evolution of body fat and insulin resistance was independent of changes in brown and beige fat markers. These data suggest that diet-induced effects on body fat and insulin resistance are independent of subcutaneous abdominal WAT browning in people with obesity.

    Purpose It is still unclear whether the longitudinal anal muscles or conjoint longitudinal coats (CLCs) are attached to the vagina, although such an attachment, if present, would appear to make an important contribution to the integrated supportive system of the female pelvic floor. Materials and Methods Using immunohistochemistry for smooth muscle actin, we examined semiserial frontal sections of 1) eleven female late-stage fetuses at 28-37 weeks of gestation, 2) two female middle-stage fetus (2 specimens at 13 weeks), and, 3) six male fetuses at 12 and 37 weeks as a comparison of the morphology. Results In late-stage female fetuses, the CLCs consistently (11/11) extended into the subcutaneous tissue along the vaginal vestibule on the anterior side of the external anal sphincter. Lateral to the CLCs, the external anal sphincter also extended anteriorly toward the vaginal side walls. The anterior part of the CLCs originated from the perimysium of the levator ani muscle without any contribution of the rectal longitudinal muscle layer. However, in 2 female middle-stage fetuses, smooth muscles along the vestibulum extended superiorly toward the levetor ani sling. In male fetuses, the CLCs were separated from another subcutaneous smooth muscle along the scrotal raphe (posterior parts of the dartos layer) by fatty tissue. Conclusion In terms of topographical anatomy, the female anterior CLCs are likely to correspond to the lateral extension of the perineal body (a bulky subcutaneous smooth muscle mass present in adult women), supporting the vaginal vestibule by transmission of force from the levator ani.

The aim of this study was to administer the anti-inflammatory cytokine, recombinant human interleukin-10 (rHuIL-10), for 28 days in patients with chronic hepatitis C and to assess the safety and measure the effect on alanine aminotransferase (ALT, a marker of hepatic inflammation) levels and serum hepatitis C virus (HCV) RNA values. Three treatment-naive and 13 interferon (IFN) nonresponder patients (total 16 patients) with compensated chronic HCV infection were enrolled in this study. Patients were randomized to receive rHuIL-10 at a dose of 4 or 8 microg/kg/day as a single daily subcutaneous injection for 28 days. ALT values and serum HCV RNA were measured at days 0, 1, 3, 8, 15, 22, and 28 during therapy and at follow-up 2 and 4 weeks after cessation of the 4-week treatment period. ALT values normalized in 9 of 16 patients during therapy and remained normal until the end of treatment in 8 patients. The decreases in ALT values occurred in both the 4 microg and 8 microg dosage groups and were seen in both IFN naive and nonresponder patients. Mean ALT values fell significantly during the study period but usually returned to pretreatment levels by the end of the 4-week follow-up period (p or =1.5 log during the study.) The drug was well tolerated, with no adverse symptoms noted. Platelet counts fell transiently to 73,000 and 63,000 in 2 patients. No other toxicity was observed, and no patients discontinued therapy. In chronic hepatitis C, short-term therapy with IL-10 was well tolerated and caused transient normalization of ALT values in 50% of patients, which returned to pretreatment levels on cessation of treatment. There were no significant changes observed in serum HCV RNA concentrations during the study. These immunomodulatory effects are similar to those observed with ribavirin monotherapy in chronic hepatitis C. Further study of rHuIL-10 alone or in

    Full Text Available Microscopic peculiarities stemming from a temperature increase in subcutaneous adipose tissue (sWAT after applying a radio-frequency (RF current, must be strongly dependent on the type of sWAT. This effect is connected with different electrical conductivities of pathways inside (triglycerides in adipocytes and outside (extra-cellular matrix the cells and to the different weighting of these pathways in hypertrophic and hyperplastic types of sWAT. The application of the RF current to hypertrophic sWAT, which normally has a strongly developed extracellular matrix with high concentrations of hyaluronan and collagen in a peri-cellular space of adipocytes, can produce, micro-structurally, a highly inhomogeneous temperature distribution, characterized by strong temperature gradients between the peri-cellular sheath of the extra-cellular matrix around the hypertrophic adipocytes and their volumes. In addition to normal temperature effects, which are generally considered in body contouring, these temperature gradients can produce thermo-mechanical stresses on the cells' surfaces. Whereas these stresses are relatively small under normal conditions and cannot cause any direct fracturing or damage of the cell structure, these stresses can, under some supportive conditions, be theoretically increased by several orders of magnitude, causing the thermo-mechanical cell damage. This effect cannot be realized in sWAT of normal or hyperplastic types where the peri-cellular structures are under-developed. It is concluded that the results of RF application in body contouring procedures must be strongly dependent on the morphological structure of sWAT.

    Migraine is a common and incapacitating neurologic disorder manifesting with episodic moderate to a severe headache and other symptoms such as photophobia, phonophobia, nausea, and vomiting. Triptans and ergot compounds have been used as treatment options for an acute migraine headache for many years. Triptans are considered the first line of treatment in patients with moderate to a severe migraine. Although the triptans are commonly used at any time during a migraine attack; they are more efficacious when used in the early stages of a migraine. Intravenous valproic acid has been shown to be well tolerated, safe, and with rapid onset of action in patients with acute moderate to severe and even refractory migraine. Sodium valproate is a Food and Drug Administration (FDA)-approved drug for prophylaxis of a migraine with and without aura. In this study, the main goal was to compare the effectiveness of sumatriptan versus valproate in an acute migraine. A randomized clinical trial including 37 patients with an acute migraine was considered to compare the effectiveness of sumatriptan versus valproate. The patients were divided into two groups. In first group, 6 mg subcutaneous of sumatriptan and in the second group 15 mg/Kg of valproate was administered. The outcomes including pain and drug adverse effects were compared across the groups. A total of 37 patients (7 male and 30 female) were evaluated in two groups. The difference between two groups regarding sex and age was not significant (P>0.05). The mean pain scores reduced from 8.3 to 4.7 and from 8.3 to 2.2 after one hour of treatment in sumatriptan and valproate groups, respectively. Response to treatment in valproate group was faster and more effective than sumatriptan group (Pvalproate was more effective and with the faster response in patients with an acute migraine in comparison with sumatriptan without any recurrence and remarkable side effects.

    Full Text Available O enfisema subcutâneo é uma complicação relativamente comum na sequência de técnicas invasivas, procedimentos cirúrgicos e algumas patologias médicas. Na maior parte dos casos apenas causa sintomatologia minor e o tratamento é habitualmente conservador. Mesmo quando grave, raramente tem consequências patofisiológicas significativas, apesar de ser extremamente desconfortável para o doente. Os autores descrevem um caso clínico de enfisema subcutâneo maciço, de rápida instalação, após saída acidental de tubo de drenagem torácica, em doente com pneumotórax espontâneo secundário e fístula broncopleural. O enfisema foi tratado através da colocação, sob anestesia local, de dois drenos subcutâneos na parede anterossuperior do tórax, conectados a sacos de drenagem. Após a colocação dos drenos subcutâneos verificou-se uma franca melhoria clínica do doente, com descompressão eficaz do enfisema subcutâneo. No presente caso clínico, a técnica de drenagem do enfisema maciço mostrou-se simples, segura e eficaz, permitindo o alívio sintomático imediato.Massive subcutaneous emphysema is a relatively common complication in invasive techniques, surgical practice and some medical conditions. Subcutaneous emphysema is usually treated conservatively and may only cause minimal symptoms. Even when it is severe, subcutaneous emphysema rarely has pathophysiologic consequences, but it is extremely uncomfortable for the patient. The authors report a case of massive and rapid developing subcutaneous emphysema following chest tube displacement in a patient with spontaneous secondary pneumothorax and large air leak. The emphysema was treated with two subcutaneous drains, inserted using local anesthesia, on both sides of the chest (antero-superior thoracic wall, connected to drainage bags. The drains produced a dramatic clinical improvement and provided effective decompression of the subcutaneous emphysema. In this clinical case, the

    Alemtuzumab was superior on clinical and magnetic resonance imaging (MRI) outcomes versus subcutaneous interferon beta-1a in phase 3 trials in patients with relapsing-remitting multiple sclerosis. To examine quality-of-life (QoL) outcomes in the alemtuzumab phase 3 trials. Patients who were treatment naive (Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis I [CARE-MS I]) or had an inadequate response to prior therapy (CARE-MS II) received annual courses of alemtuzumab 12 mg/day at baseline (5 days) and Month 12 (3 days) or subcutaneous interferon beta-1a 44 µg three times/week. QoL was measured every 6 or 12 months using Functional Assessment of Multiple Sclerosis (FAMS), European Quality of Life-5 Dimensions (EQ-5D) and its visual analog scale (EQ-VAS), and 36-Item Short-Form Survey (SF-36). Statistically significant improvements from baseline with alemtuzumab were observed on all three QoL instruments at the earliest post-baseline assessment and sustained through Year 2. Statistically significant greater QoL improvements over subcutaneous interferon beta-1a were seen at all time points in CARE-MS II with FAMS, EQ-VAS and SF-36 physical component summary, and in CARE-MS I with FAMS. Patients treated with alemtuzumab had improvements in physical, mental, and emotional QoL regardless of treatment history. Improvements were significantly greater with alemtuzumab versus subcutaneous interferon beta-1a on both disease-specific and general measures of QoL.

    This study assessed patient experiences of using an autoinjector device to self-administer subcutaneous belimumab for the treatment of systemic lupus erythematosus (SLE). Satisfaction, ease and convenience of use, and confidence with the device were assessed, in addition to overall experience with belimumab. This cross-sectional study was conducted among patients who completed a phase IIb open-label, multi-dose usability, tolerability, and safety study of subcutaneous belimumab (NCT02124798), in which patients receiving intravenous belimumab or subcutaneous belimumab using a prefilled syringe were switched to eight weekly self-administered doses of subcutaneous belimumab using the autoinjector. This follow-up study comprised an online/paper questionnaire and qualitative telephone interviews. In total, 43 patients receiving belimumab completed the questionnaire, 21 of whom also completed a follow-up telephone interview. Qualitative interviews indicated that 17 of 21 (81%) patients had a positive experience using the autoinjector; all patients considered the autoinjector to be convenient. Of the 42 patients who switched from intravenous belimumab to the autoinjector, 32 (76%) expressed a preference for the autoinjector over intravenous administration; reasons included convenience, time saved, cost, and reduced injection pain. The most commonly reported disadvantage of the autoinjector was injection discomfort (n = 5 [24%]; qualitative interview). Compared with intravenous administration, the autoinjector improved ability to work (17 of 29 [59%] of those employed) and carry out daily activities (40%). Patients with SLE reported high levels of satisfaction with the belimumab autoinjector and preferred the autoinjector to intravenous administration, citing advantages such as time saved, cost, and improved ability to work and carry out daily activities.

    To compare the effects of subcutaneous penile injection of basic fibroblast growth factor (bFGF)-hydrogel and intracavernous injection of human adipose-derived stem cells (h-ADSCs) on improving erectile function in a rat model of cavernous nerve injury. Adult male Sprague-Dawley rats were randomly divided into 5 groups (n = 10 per group): age-matched control (normal group), bilateral cavernous nerve injury (BCNI group), penile subcutaneous injection of hydrogel after BCNI (hydrogel group), penile subcutaneous injection of bFGF-hydrogel after BCNI (bFGF-hydrogel group) and intracavernous injection of h-ADSCs after BCNI (ADSC group). Four weeks after the treatment, all rats underwent an erectile function test. Then, penile tissue was harvested for immunohistological analysis of bFGF, phalloidin, and cluster of differentiation (CD) 31. The cyclic guanosine monophosphate (cGMP) level of the corpus cavernosum was quantified by cGMP assay. From the functional test and immunohistological result, we observed that bFGF-hydrogel and h-ADSCs injection significantly elevated intracavernous pressure. The evaluation of filamentous actin content, CD31 expression, and cGMP concentration in the corpus cavernosum were meaningfully increased in the bFGF-hydrogel and ADSC groups compared with BCNI group. The bFGF released from bFGF-hydrogel prevented smooth muscle atrophy. Moreover, bFGF expression was significantly increased in bFGF-hydrogel group. The subcutaneous injection of bFGF-hydrogel prevented smooth muscle atrophy, increased the intracavernous pressure, and improved erectile function like an intracavernous injection of h-ADSCs.

    The subcutaneous pedicled V-Y advancement flap is useful for the repair of small and medium-sized defects in areas where it is easy to obtain a good subcutaneous pedicle (upper lip, cheek, eyebrow, and nasal tip and ala). The almost complete absence of subcutaneous tissue on the anterior aspect of the auricle of the ear can limit the use of this approach in this region. We present 4 patients in whom subcutaneous pedicled V-Y advancement flaps were used to repair surgical defects of the helix, scaphoid fossa, and antitragus, achieving a good functional and aesthetic result in all cases.

    Full Text Available An influenza vaccination often causes local reactions, such as induration and erythema at the injection site, and occasionally systemic reactions. The association between these reactions and influenza vaccinations has not been fully recognized. By contrast, granuloma annulare (GA is an idiopathic, palisaded, granulomatous condition, and has some clinical variants, including localized, generalized, perforating, and subcutaneous types. We report a 76-year-old woman, who was suffering from a tender subcutaneous nodule on her left upper arm. One month before, she had just received influenza vaccination on the same area. Histological analysis demonstrated that subcutaneous tissue contained numerous large areas of necrosis, surrounded by palisaded epithelioid histiocytes. We diagnosed our case as a subcutaneous type of GA following influenza vaccination. To our knowledge, this is the first report of GA associated with influenza vaccination.

    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.

    In patients with primary antibody deficiencies, subcutaneous administration of IgG (SCIG) replacement is effective, safe, well-tolerated, and can be self-administered at home. A new SCIG replacement at 20% concentration (Hizentra®) has been developed and has replaced Vivaglobin® (SCIG 16%). An observational prospective multi-centric open-label study, with retrospective comparison was conducted in 15 Italian centers, in order to investigate whether and to what extent switching to Hizentra® would affect frequency of infusions, number of infusion sites, patients' satisfaction, and tolerability in patients previously treated with Vivaglobin® or intravenous immunoglobulins (IVIG). Any variations of dosage, frequency and duration of the infusions, and of number of infusion sites induced by Hizentra® with respect to the former treatment were recorded. Practical advantages and disadvantages of Hizentra®, with respect to the medicinal product formerly used, and the variations in patients' therapy-related satisfaction were monitored by means of the TSQM (Treatment Satisfaction Questionnaire for Medication); number, frequency, and duration of infectious events and adverse effects were recorded. Eighty-two patients switched to Hizentra®: 19 (23.2%) from IVIG and 63 (76.8%) from Vivaglobin®. The mean interval between infusions was not affected by the shift (7.0 ± 2.0 days with previous treatment versus 7.1 ± 1.2 during Hizentra®). A decrease in the number of infusion sites with Hizentra® was recorded in 12 out of 56 patients for whom these data were available. At 6 months, 89.7% of patients were satisfied with Hizentra®; no difference in terms of effectiveness, side effects, convenience, and global satisfaction was observed. No difference in the incidence of adverse events was reported.

    Ramírez Soto, Max Carlos; Malaga, German

    2017-10-01

    There is a worrying lack of epidemiological data on the geographical distribution and burden of subcutaneous mycoses in Peru, hindering the implementation of surveillance and control programs. This study aimed to estimate the disease burden of subcutaneous mycoses in Peru and identify which fungal species were commonly associated with these mycoses. We performed a meta-analysis after a systematic review of the published literature in PubMed, LILACS, and SciELO to estimate the burden of subcutaneous mycoses in 25 regions in Peru. The disease burden was determined in terms of prevalence (number of cases per 100,000 inhabitants) and the number of reported cases per year per region. A total of 26 studies were eligible for inclusion. Results showed that sporotrichosis was the most common subcutaneous mycosis (99.7%), whereas lobomycosis, chromoblastomycosis, and subcutaneous phaeohyphomycosis were rare. Cases of eumycetoma and subcutaneous zygomycosis were not found. Of the 25 regions, the burden of sporotrichosis was estimated for four regions classified as endemic; in nine regions, only isolated cases were reported. The highest burden of sporotrichosis was in Apurimac (15 cases/100,000 inhabitants; 57 cases/year), followed by Cajamarca (3/100,000 inhabitants; 30/year), Cusco (0.5/100,000 inhabitants; 4/year), and La Libertad (0.2/100,000 inhabitants; 2/year). In two regions, the mycoses predominantly affected children. Sporotrichosis is the most common subcutaneous mycosis in Peru, with a high disease burden in Apurimac. Chromoblastomycosis, lobomycosis, and subcutaneous phaeohyphomycosis are rare mycoses in Peru. © 2017 The International Society of Dermatology.

    Randomized clinical trials support the use of implantable defibrillators for mortality reduction in specific populations at high risk for sudden cardiac death. Conventional transvenous defibrillator systems are limited by implantation-associated complications, infection, and lead failure, which may lead to delivery of inappropriate shocks and diminish survival. The development of a fully subcutaneous defibrillator may represent a valuable addition to therapies targeted at sudden death prevention. The PubMed database was searched to identify all clinical reports of the subcutaneous defibrillator from 2000 to the present. We reviewed all case series, cohort analyses, and randomized trials evaluating the safety and efficacy of subcutaneous defibrillators. The subcutaneous defibrillator is a feasible development in sudden cardiac death therapy and may be useful particularly to extend defibrillator therapy to patients with complicated anatomy, limited vascular access, and congenital disease. The subcutaneous defibrillator should not be considered in patients with an indication for cardiac pacing or who have ventricular tachycardia responsive to antitachycardia pacing. Further investigation is needed to compare long-term, head-to-head performance of subcutaneous defibrillators and conventional transvenous defibrillator systems. Published by Elsevier Inc.

    Some rheumatoid arthritis (RA) patients initially respond to treatment with infliximab (IFX), but subsequently their responsiveness decreases. Our objective was to evaluate the efficacy and safety of switching from IFX to subcutaneous golimumab (GLM-SC) in RA patients. Thirty-three patients who had been treated for a mean 4.4 years with IFX (3-6 mg/kg/8 weeks) were switched to GLM-SC to control disease activity or adverse events. The patients with low disease activity (LDA) or remission were divided into two groups: the LDA group and the LDA every 8 weeks (q8w) group, which included patients with LDA or remission who switched to GLM therapy with 50 mg at 4- and 8-week intervals, respectively. The moderate disease activity (MDA) group included patients with MDA who switched to GLM therapy with 50 mg at 4-week intervals. Effects of the IFX to GLM-SC switch were evaluated at weeks 12, 24, and 52 after switching. The mean disease activity score 28-ESR and -C-reactive protein values in the LDA and LDAq8w groups were maintained from baseline throughout the 52-week treatment period. The mean disease activity score 28 values at 12, 24, and 52 weeks in the MDA group were improved significantly compared with baseline. Treatment discontinuations due to adverse events occurred in one patient in the MDA group, and no serious adverse events occurred during the observation period in the LDA group or the LDAq8w group. The GLM continuation rates at 52 weeks were 100% in the LDA and LDAq8w groups and 83.3% in the MDA group. Thus, GLM-SC treatment regimens were effective in controlling disease activity and improving the clinical response related to adverse events caused by IFX. The clinical efficacy of GLM-SC was sustained or improved in patients who switched from IFX without serious safety concerns.

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

    Today there are different subcutaneous and three oral applicable medications for prevention of venous thromboembolism after knee and hip replacement. It is a general opinion that patients will prefer oral administration. However, until today there has been no study that analysed patient preferences and motives for deciding on the kind of administration. These data would be of interest since the consideration of patient preferences could improve adherence. The present study analysed patient preferences regarding oral or subcutaneous administration of medication after elective hip or knee replacement surgery. The results will have implications for clinical practice and for decision-making concerning the kind of administration. This prospective, multi-centric, observational study was conducted in six emergency hospitals and six rehabilitation hospitals. 178 current hip and knee replacement patients undergoing thromboprophylaxis and at least one further oral medication were interviewed. Subjective assessment data of patients were collected on study-specific questionnaires (epidemiological data, amount and background of general oral medication, details on subcutaneous thromboprophylaxis, preference of administration, causes for preference). 71.91 % of the interviewed patients preferred the daily intake of a tablet, whereas only 14.61 % favoured the daily subcutaneous injection. Main causes for the preference of oral administration were easier (86.6 % of nominations) and less complex (73.1 % of nominations) handling. 70.9 % reported that one more oral application would be unproblematic. Painlessness of oral administration was relevant for 65.7 %. Causes for preferring subcutaneous administration were "safety" (55.3 % of nominations) and an assumption of a generally better effectivity of subcutaneous (47.4 % of nominations) administration. Subjective discomfort induced by subcutaneus administration increased with the time interval since surgery. Less than 5 % of patients

    To determine the compound Daqiqi decoction( CDQD) combined cisplatin plays on the cell apoptosis of subcutaneous transplanted ovarian cancer in nude mice, to provide theory evidence for clinical treatment. Making the models of subcutaneous transplanted ovarian cancer in nude mice, and divide the 40 mice with tumor into 5 groups (n = 8), the model control group, CDQD low dosed group, CDQD high dosed group, cisplatin group, cisplatin combined CDQD group, killing all the mice after 3 weeks' treatment and stripping tumors. Measure the volume and weight of the tumor and calculate tumor growth curve damps, the inhibition rate. Examining the expression of the Bcl-2(B-cell leukemia /lymphoma 2) and Bax (Bcl-2 associated x protein) mRNA and protein by the RT-PCR and the Western blot. (O)The tumor weight shows that there was certain lighter effect in each CDQD group, and compared with cisplatin groups has no statistical significance, the cisplatin combined CDQD group is obviously lighter than that of the other group(P curve damps shows that compared with model control group, the treatment group tumors had some extent narrowing (P < 0.01). (2) RT-PCR results: Bax (Bcl-2 associated x protein) mRNA expression shows that compared with model control group, the treatment group has increased (P < 0.01), and the cisplatin combined CDQD group compared with the other group is the highest, there was significant difference with the rest of the treatment group (P < 0.01). In the Bcl-2 mRNA express lowest in cisplatin combined CDQD group (P < 0.01), there has no difference between CDQD high dose group and cisplatin group. (Western blot shows: compared with model control group, the Bax protein of treatment group has increased expression (P < 0.01), the expression of Bax protein in cisplatin combined CDQD group is the highest(P < 0.01). There has no difference between CDQD high dose group and cisplatin group. The Bcl-2 protein expression of the cisplatin combined CDQD group is the lowest (P

    High-energy diets are among the main causes of the global epidemic of metabolic disorders, including obesity and type 2 diabetes. The mechanisms of high-energy-diet-induced metabolic disorders are complex and largely unknown. The non-receptor tyrosine kinase c-Abl plays an important role in adipogenesis in vitro but its role in vivo in the regulation of metabolism is still elusive. Hence, we sought to address the role of c-Abl in diet-induced obesity and obesity-associated insulin resistance. The expression of c-Abl in different fat tissues from obese humans or mice fed a high-fat diet (HFD) were first analysed by western blotting and quantitative PCR. We employed conditional deletion of the c-Abl gene (also known as Abl1) in adipose tissue using Fabp4-Cre and 6-week-old mice were fed with either a chow diet (CD) or an HFD. Age-matched wild-type mice were treated with the c-Abl inhibitor nilotinib or with vehicle and exposed to either CD or HFD, followed by analysis of body mass, fat mass, glucose and insulin tolerance. Histological staining, ELISA and biochemical analysis were used to clarify details of changes in physiology and molecular signalling. c-Abl was highly expressed in subcutaneous fat from obese humans and HFD-induced obese mice. Conditional knockout of c-Abl in adipose tissue improved insulin sensitivity and mitigated HFD-induced body mass gain, hyperglycaemia and hyperinsulinaemia. Consistently, treatment with nilotinib significantly reduced fat mass and improved insulin sensitivity in HFD-fed mice. Further biochemical analyses suggested that c-Abl inhibition improved whole-body insulin sensitivity by reducing HFD-triggered insulin resistance and increasing adiponectin in subcutaneous fat. Our findings define a new biological role for c-Abl in the regulation of diet-induced obesity through improving insulin sensitivity of subcutaneous fat. This suggests it may become a novel therapeutic target in the treatment of metabolic disorders.

  12. Subcutaneous bortezomib in multiple myeloma patients induces similar therapeutic response rates as intravenous application but it does not reduce the incidence of peripheral neuropathy.

    Full Text Available Subcutaneous (SC application of bortezomib has been recently introduced as a new application route in multiple myeloma (MM patients. We performed an analysis to compare the outcomes of bortezomib-based therapy in multiple myeloma (MM patients treated using either intravenous (IV or subcutaneous (SC route of administration.During January 2012 through December 2013, we performed a retrospective analysis of 446 patients with MM treated with bortezomib-based regimens (either once weekly - 63% or twice weekly - 27% in both, the first line setting, and in relapse, with separate analysis of patients undergoing autologous stem cell transplantation. We assessed the response rates and toxicity profiles in both, IV and SC route of bortezomib administration.The response rates in both IV and SC arm were similar with overall response rate 71.7% vs 70.7%, complete remissions in 13.9% vs 8.6%, very good partial remissions in 30.8% vs 34.5% and partial remissions in 27% vs 27.6%. The most frequent grade ≥ 3 toxicities were anemia, thrombocytopenia and neutropenia, with no significant differences between IV and SC group. There were no significant differences in the rate of peripheral neuropathy (PN. PN of any grade was present in 48% in the IV arm and in 41% in the SC arm. PN grade ≥ 2 was present in 20% vs 18% and PN grade ≥ 3 was present in 6% vs 4%.We conclude that subcutaneous application of bortezomib has similar therapeutic outcomes and toxicity profile as intravenous route of application. In our cohort there was no difference in the incidence of PN, suggesting that PN is dose dependent and might be reduced by lower intensity schemes rather than by the route of administration.

    Full Text Available BACKGROUND: We previously demonstrated the benefits of daily, oral pentosan polysulfate (PPS treatment in a rat model of mucopolysaccharidosis (MPS type VI. Herein we compare these effects to once weekly, subcutaneous (s.c. injection. The bioavailability of injected PPS is greater than oral, suggesting better delivery to difficult tissues such as bone and cartilage. Injected PPS also effectively treats osteoarthritis in animals, and has shown success in osteoarthritis patients. METHODOLOGY/PRINCIPAL FINDINGS: One-month-old MPS VI rats were given once weekly s.c. injections of PPS (1, 2 and 4 mg/kg, human equivalent dose (HED, or daily oral PPS (4 mg/kg HED for 6 months. Serum inflammatory markers and total glycosaminoglycans (GAGs were measured, as were several histological, morphological and functional endpoints. Overall, weekly s.c. PPS injections led to similar or greater therapeutic effects as daily oral administration. Common findings between the two treatment approaches included reduced serum inflammatory markers, improved dentition and skull lengths, reduced tracheal deformities, and improved mobility. Enhanced effects of s.c. treatment included GAG reduction in urine and tissues, greater endurance on a rotarod, and better improvements in articular cartilage and bone in some dose groups. Optimal therapeutic effects were observed at 2 mg/kg, s.c.. No drug-related increases in liver enzymes, coagulation factor abnormalities or other adverse effects were identified following 6 months of s.c. PPS administration. CONCLUSIONS: Once weekly s.c. administration of PPS in MPS VI rats led to equal or better therapeutic effects than daily oral administration, including a surprising reduction in urine and tissue GAGs. No adverse effects from s.c. PPS administration were observed over the 6-month study period.

    Supra-nutritional doses of curcumin, derived from the spice Curcuma longa, have been proposed as a potential treatment of inflammation and metabolic disorders related to obesity. The aim of the present study was to test whether Curcuma longa extract rich in curcumin and associated with white pepper (Curcuma-P®), at doses compatible with human use, could modulate systemic inflammation in diet-induced obese mice. We questioned the potential relevance of changes in adiposity and gut microbiota in the effect of Curcuma-P® in obesity. Mice were fed either a control diet (CT), a high fat (HF) diet or a HF diet containing Curcuma longa extract (0.1 % of curcumin in the HF diet) associated with white pepper (0.01 %) for four weeks. Curcumin has been usually combined with white pepper, which contain piperine, in order to improve its bioavailability. This combination did not significantly modify body weight gain, glycemia, insulinemia, serum lipids and intestinal inflammatory markers. Tetrahydrocurcumin, but not curcumin accumulated in the subcutaneous adipose tissue. Importantly, the co-supplementation in curcuma extract and white pepper decreased HF-induced pro-inflammatory cytokines expression in the subcutaneous adipose tissue, an effect independent of adiposity, immune cells recruitment, angiogenesis, or modulation of gut bacteria controlling inflammation. These findings support that nutritional doses of Curcuma longa, associated with white pepper, is able to decrease inflammatory cytokines expression in the adipose tissue and this effect could be rather linked to a direct effect of bioactive metabolites reaching the adipose tissue, than from changes in the gut microbiota composition.

    Background Lipedema is a common painful subcutaneous adipose tissue (SAT) disorder in women affecting the limbs. SAT therapy is a manual therapy to improve soft tissue quality. Objective Determine if SAT therapy improves pain and structure of lipedema SAT. Design Single arm prospective pilot study. Setting Academic medical center. Patients Seven women, 46 ± 5 years, weight 90 ± 19 kg, with lipedema. Intervention Twelve 90-min SAT therapy sessions over 4 weeks. Outcomes Dual X-ray absorptiometry (DXA) scans, SAT ultrasound (Vevo 2100), leg volumetrics, skin caliper assessment, tissue exam, weight, resting metabolic rate, pain assessment, lower extremity functional scale (LEFS) and body shape questionnaire (BSQ) at baseline and end of study. Results Weight, resting metabolic rate and BSQ did not change significantly. Limb fat over total body fat mass (p = 0.08) and trunk fat over total body mass trended down from baseline (p = 0.08) by DXA. Leg volume and caliper assessments in eight of nine areas (p SAT structure in some subjects. Side effects included pain, bruising, itching, swelling and gastroesophageal reflux disease. All women said they would recommend SAT therapy to other women with lipedema. Limitations Small number of subjects. Conclusion SAT therapy in 4 weeks improved tissue structure, perceived leg function, and volume although shape was not affected. While side effects of SAT therapy were common, all women felt the therapy was beneficial.

  17. Spatial anisotropy analyses of subcutaneous tissue layer: potential insights into its biomechanical characteristics.

    As the intermediate layer between the muscle and skin, the subcutaneous tissue frequently experiences shear and lateral stresses whenever the body is in motion. However, quantifying such stresses in vivo is difficult. The lack of such measures is partly responsible for our poor understanding of the biomechanical behaviors of subcutaneous tissue. In this study, we employ both ultrasound imaging and a novel spatial anisotropy measure - incorporating Moran's I spatial autocorrelation calculations - to investigate the structuromechanical features of subcutaneous tissues within the extremities of 16 healthy volunteers. This approach is based on the understanding that spatial anisotropy can be an effective surrogate for the summative, tensile forces experienced by biological tissue. We found that spatial anisotropy in the arm, thigh and calf was attributed to the echogenic bands spanning the width of the ultrasound images. In both univariable and multivariable analyses, the calf was significantly associated with greater anisotropy compared with the thigh and arm. Spatial anisotropy was inversely related to subcutaneous thickness, and was significantly increased with longitudinally oriented probe images compared with transversely orientated images. Maximum peaks in spatial anisotropy were frequently observed when the longitudinally oriented ultrasound probe was swept across the extremity, suggesting that longitudinal channels with greater tension exist in the subcutaneous layer. These results suggest that subcutaneous biomechanical tension is mediated by collagenous/echogenic bands, greater in the calf compared with the thigh and arm, increased in thinner individuals, and maximal along longitudinal trajectories parallel to the underlying muscle. Spatial anisotropy analysis of ultrasound images has yielded meaningful patterns and may be an effective means to understand the biomechanical strain patterns within the subcutaneous tissue of the extremities. © 2011 The Authors

    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

    Alternative techniques to the traditional 3-incision subcutaneous implantation of the subcutaneous implantable cardioverter-defibrillator may offer procedural and cosmetic advantages. We evaluate 4 different implant techniques of the subcutaneous implantable cardioverter-defibrillator. Patients implanted with subcutaneous implantable cardioverter-defibrillators from 2 hospitals between 2009 and 2016 were included. Four implantation techniques were used depending on physician preference and patient characteristics. The 2- and 3-incision techniques both place the pulse generator subcutaneously, but the 2-incision technique omits the superior parasternal incision for lead positioning. Submuscular implantation places the pulse generator underneath the serratus anterior muscle and subfascial implantation underneath the fascial layer on the anterior side of the serratus anterior muscle. Reported outcomes include perioperative parameters, defibrillation testing, and clinical follow-up. A total of 246 patients were included with a median age of 47 years and 37% female. Fifty-four patients were implanted with the 3-incision technique, 118 with the 2-incision technique, 38 with submuscular, and 37 with subfascial. Defibrillation test efficacy and shock lead impedance during testing did not differ among the groups; respectively, P=0.46 and P=0.18. The 2-incision technique resulted in the shortest procedure duration and time-to-hospital discharge compared with the other techniques (P<0.001). A total of 18 complications occurred, but there were no significant differences between the groups (P=0.21). All infections occurred in subcutaneous implants (3-incision, n=3; 2-incision, n=4). In the 2-incision group, there were no lead displacements. The presented implantation techniques are feasible alternatives to the standard 3-incision subcutaneous implantation, and the 2-incision technique resulted in shortest procedure duration. © 2017 American Heart Association, Inc.

    2016-11-01

    The availability of acellular dermal matrix (ADM) and synthetic mesh products has prompted plastic surgeons to revisit subcutaneous implant-based breast reconstruction. The literature is limited, however, with regards to evidence on patient selection, techniques, and outcomes. A systematic review of the Medline and Cochrane databases was performed for original studies reporting breast reconstruction with ADM or mesh, and subcutaneous implant placement. Studies were analyzed for level of evidence, inclusion/exclusion criteria for subcutaneous reconstruction, reconstruction characteristics, and outcomes. Six studies (186 reconstructions) were identified for review. The majority of studies (66.7%) were level IV evidence case series. Eighty percent of studies had contraindications for subcutaneous reconstruction, most commonly preoperative radiation, high body mass index, and active smoking. Forty percent of studies commenting on patient selection assessed mastectomy flap perfusion for subcutaneous reconstruction. Forty-five percent of reconstructions were direct-to-implant, 33.3% 2-stage, and 21.5% single-stage adjustable implant, with ADM utilized in 60.2% of reconstructions versus mesh. Pooled complication rates included: major infection 1.2%, seroma 2.9%, hematoma 2.3%, full nipple-areola complex necrosis 1.1%, partial nipple-areola complex necrosis 4.5%, major flap necrosis 1.8%, wound healing complication 2.3%, explantation 4.1%, and grade III/IV capsular contracture 1.2%. Pooled short-term complication rates in subcutaneous alloplastic breast reconstruction with ADM or mesh are low in preliminary studies with selective patient populations, though techniques and outcomes are variable across studies. Larger comparative studies and better-defined selection criteria and outcomes reporting are needed to develop appropriate indications for performing subcutaneous implant-based reconstruction.

    The migration of fluorescein isothiocyanate labelled lymphocytes through the tracheobronchial mucosa has been studied in cattle. Following intratracheal inoculation of labelled non-infected autologous lymphocytes and bovine leukosis virus (BLV) infected heterologous (presumed allogeneic) lymphocytes, the labelled lymphocytes appeared in the blood circulation between 4 and 7 days post inoculation. Following intravenous inoculation of labelled autologous lymphocytes, the cells could be detected in the circulation for 10 days post inoculation whereas BLV infected and non-infected heterologous lymphocytes could be detected for only 2 days. The migration of BLV-infected heterologous lymphocytes through the tracheobronchial mucosa caused a delay in the appearance of labelled lymphocytes in the circulation and a corresponding delay in the appearance of BLV antibodies. Comparison was made of the effect of two different routes of inoculation, subcutaneous and intratracheal on the incubation period as indicated by the detection of antibody. Subcutaneous inoculation of 1 X 10(4), 5 X 10(3), 1 X 10(3) of lymphocytes from a BLV infected cow caused seroconversion whereas 5 X 10(2) cells did not. Intratracheal inoculation of 5 X 10(3) cells caused sero-conversion. One animal did not develop BLV antibody until 30 weeks after inoculation although BLV could be isolated from the blood at 24 and 26 weeks post inoculation.

    Full Text Available Porous microcarriers were fabricated from synthesized poly(γ-benzyl-L-glutamate (PBLG polymer to engineer adipose tissue with lobule-like structure via the injectable approach. The adipogenic differentiation of human adipose-derived stem cells (hASCs seeded on porous PBLG microcarriers was determined by adipogenic gene expression and glycerol-3-phosphate dehydrogenase enzyme activity. In vitro adipogenic cultivation was performed for 7 days, and induced hASC/PBLG complex (Adi-ASC/PBLG group was subcutaneously injected into nude mice. Injections of PBLG microcarriers alone (PBLG group and non-induced hASC/PBLG complex (ASC/PBLG group served as controls. Newly formed tissues were harvested after 4 and 8 weeks. Generation of subcutaneous adipose tissue with typical lobule-like structure separated by fibrous septa was observed upon injection of adipogenic-induced hASC/microsphere complex. Adipogenesis significantly increased in the Adi-ASC/PBLG group compared with the control groups. The angiogenesis in the engineered adipose tissue was comparable to that in normal tissue as determined by capillary density and luminal diameter. Cell tracking assay demonstrated that labeled hASCs remained detectable in the neo-generated tissues 8 weeks post-injection using green fluorescence protein-labeled hASCs. These results indicate that adipose tissue with typical lobule-like structure could be engineered using injectable porous PBLG microspheres loaded with adipogenic-induced hASCs.

    Internal plexiform neurofibromas are a major cause of adverse outcomes in patients with neurofibromatosis 1 (NF1). We investigated the relationship of the numbers of subcutaneous neurofibromas of the scalp or body to internal plexiform tumor volume in 120 NF1 patients who had undergone whole body magnetic resonance imaging (MRI). We identified internal plexiform neurofibromas in 55% of patients, subcutaneous neurofibromas of the body in 75%, and subcutaneous neurofibromas of the scalp in 45%. The number of subcutaneous neurofibromas of the body and scalp were associated with each other (Spearman's Rho = 0.36; P scalp. The total internal tumor volume was associated with the number of subcutaneous neurofibromas of the body (OR = 1.00086 per neurofibroma, 1.000089-1.0016, P = 0.029) and of the scalp (OR = 1.056 per neurofibroma, 1.029-1.083, P scalp and body are associated with internal plexiform tumor burden in NF1. Recognition of these associations may improve clinical management by helping to identify patients who will benefit most from whole body MRI and more intense clinical surveillance. © 2015 Wiley Periodicals, Inc.

    The year 1952 marked the first use of subcutaneous immunoglobulin therapy to treat primary immunodeficiency disease. Subsequently, intramuscular and then intravenous administration became the norm in the United States and most of Europe. Intravenous immunoglobulin therapy, however, can be burdensome and often causes systemic side effects. To overcome obstacles presented by the intravenous route of administration, subcutaneous preparations were developed. To further enhance patient satisfaction, adherence, and quality of life, enzyme-enhanced subcutaneous immunoglobulin administration using hyaluronidase, an enzyme spreading agent, was studied. The dose and flow rate of traditional subcutaneous immunoglobulin infusion is limited by the inhibition of bulk fluid flow by the extracellular matrix. Recombinant human hyaluronidase, administered with or immediately prior to infusate, increases the absorption and dispersion of infused fluids and drugs. Results from a phase III clinical trial indicate that subcutaneous immunoglobulin infusion, facilitated by recombinant human hyaluronidase, is well tolerated, and delivers infusion volumes at treatment intervals and rates equivalent to intravenous administration. This review surveys the state of the art of immunoglobulin replacement therapy.

    BACKGROUND: Subcutaneous blood flow increases during sleep and we evaluated if this increase is affected by epidural anaesthesia. METHODS: Lower leg subcutaneous blood flow was determined by 133Xenon clearance in ten subjects during continous epidural anaesthesia at L2-L3 including eight hours...... of sleep, while the opper abdominal subcutaneous blood flow served as control. RESULTS: Epidural anaesthesia to the level of the umbilicus was followed by an increase in the lower leg subcutaneous blood flow fra 3.4 (1.8-6.3) to 7.8 (3.6-16.9) ml min-1 (median and range; P....4-7.6) ml min-1 100 g-1 after 88 (45-123) min. In contrast, until the period of sleep the upper abdominal region blood flow remained at 5.2 (3.2-6.4) ml min-1 100 g-1. During sleep, lower leg subcutaneous blood flow did not change significantly, but the upper abdominal flow increased to 6.2 (5.2-7.2) ml min...

  6. Role of Subcutaneous Adipose Tissue in the Pathogenesis of Insulin Resistance

    Full Text Available Burden of obesity has increased significantly in the United States over last few decades. Association of obesity with insulin resistance and related cardiometabolic problems is well established. Traditionally, adipose tissue in visceral fat depot has been considered a major culprit in development of insulin resistance. However, growing body of the literature has suggested that adipose tissue in subcutaneous fat depot, not only due to larger volume but also due to inherent functional characteristics, can have significant impact on development of insulin resistance. There are significant differences in functional characteristics of subcutaneous abdominal/truncal versus gluteofemoral depots. Decreased capacity for adipocyte differentiation and angiogenesis along with adipocyte hypertrophy can trigger vicious cycle of inflammation in subcutaneous adipose tissue and subsequent ectopic fat deposition. It is important to shift focus from fat content to functional heterogeneity in adipose tissue depots to better understand the relative role of subcutaneous adipose tissue in metabolic complications of obesity. Therapeutic lifestyle change continues to be the most important intervention in clinical practice at any level of increased adiposity. Future pharmaceutical interventions aimed at improving adipose tissue function in various subcutaneous depots have potential to help maintain adequate insulin sensitivity and reduce risk for development of insulin resistance complications.

    Subcutaneous injections allow for self-administration, but consideration of patients' perspectives on treatment choice is important to ensure adherence. Previous systematic reviews have been limited in their scope for assessing preferences in relation to other routes of administration. Our objective was to examine patients' perspectives on subcutaneously administered self-injectable medications when compared with other routes or methods of administration for the same medicines. Nine electronic databases were searched for publications since 2000 using terms pertaining to methods of administration, choice behavior, and adverse effects. Eligibility for inclusion was determined through reference to specific criteria by two independent reviewers. Results were described narratively. Of the 1726 papers screened, 85 met the inclusion criteria. Studies were focused mainly on methods of insulin administration for diabetes but also included treatments for pediatric growth disorders, multiple sclerosis, HIV, and migraine. Pen devices and autoinjectors were favored over administration with needle and syringe, particularly with respect to ergonomics, convenience, and portability. Inhalation appeared to be more acceptable than subcutaneous injection (in the case of insulin), but how subcutaneous infusion, intramuscular injection, and needle-free injection devices compare with subcutaneous injections in terms of patient preference is less certain. The review identified a number of studies showing the importance of the methods and routes of drug delivery on patient choice. However, studies were prone to bias, and further robust evidence based on methodologically sound approaches is required to demonstrate how patient choice might translate to improved adherence.

The patient’s respiratory status continued to decline requiring emergency intubation in a non-ICU setting. Four laryngoscope intubation attempts were made including an inadvertent esophageal intubation. Subsequent CT imaging revealed a tracheal defect (Figure 1, red arrow with communication to the mediastinum and air around the trachea consistent with pneumomediastinum (Figure 2, orange arrow and figure 3, yellow arrow. Pneumopericardium (figure 4, blue arrow was also evident post-intubation. The patient’s hemodynamic status remained stable. Two days following respiratory intubation subsequent chest imaging revealed resolution of the pneumomediastinum and pneumopericardium and patient continued to do well without hemodynamic compromise or presence of subcutaneous emphysema. Post-intubation tracheal perforation is a rare complication of traumatic intubation and may be managed with surgical intervention or conservative treatment (1.

    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.

    Full Text Available In this study we estimate the subcutaneous tissue counter pressure during drug infusion from a series of injections of insulin in type 2 diabetic patients using a non-invasive method. We construct a model for the pressure evolution in subcutaneous tissue based on mass continuity and the flow laws of a porous medium. For equivalent injection forces we measure the change in the infusion rate between injections in air at atmospheric pressure and in tissue. From a best fit with our model, we then determine the flow permeability as well as the bulk modulus of the tissue, estimated to be of the order 10-11-10-10 m2 and 105 Pa, respectively. The permeability is in good agreement with reported values for adipose porcine tissue. We suggest our model as a general way to estimate the pressure build-up in tissue during subcutaneous injection.

    Splenosis is a common benign condition that occurs after splenic rupture via trauma or surgery. The mechanism behind splenic cell autotransplantation begins with the splenic rupture, either from trauma or surgical removal. Splenosis is usually found incidentally and, unless symptomatic, surgical therapy is not indicated. Subcutaneous splenosis is an extremely rare form of splenosis, mostly observed in abdominal surgical scars. We report a case of subcutaneous splenosis, as well as a comprehensive review of the literature. In our case, a 43-year-old woman who had splenectomy after traumatic splenic rupture at the age of 7 years old presented for plastic reconstruction of her postoperative scar. Upon surgery, two asymptomatic subcutaneous nodules were incidentally discovered. The presence of splenic tissue was confirmed by the histological study. The nodules were not excised, as the patient was not symptomatic. PMID:23401837

    Full Text Available We are reporting a 33-year old woman with multiple skin-colored, firm, non-tender nodules of varying sizes (ranging between 1 and 1.5 cm, with limited mobility and normal overlying skin. They were distributed mainly on the palmer side of the fingers. History and laboratory examination indicated lack of systemic diseases such as diabetes, rheumatoid arthritis, and tuberculosis. Histopathologic examination confirmed the subcutaneous granuloma annulare (SGA diagnosis by showing a normal epidermis with palisading granulomas (histocytes and giant cells surrounding small areas of connective tissue degeneration (central necrobiosis and mucin accumulation in the reticular dermis and subcutaneous tissues. The patient responded well to two-session course of intra-lesional steroid injections. SGA should be considered by dermatologists in the differential diagnosis of subcutaneous nodules even without concomitant systemic disease and with rare presentation.

He developed haemorrhagic shock from a subcutaneous haematoma in his left thigh and required monitoring in the surgical intensive care unit. He stabilised with aggressive fluid resuscitation with crystalloids and blood transfusion. The recovery was complicated by an infection of the subcutaneous haematoma. Following open drainage of the infected subcutaneous haematoma, he improved and was discharged. To the best of our knowledge, this is the first reported case of a subcutaneous haematoma causing haemorrhagic shock.

    The incidence of cutaneous and subcutaneous metastases from atypical laryngeal carcinoids is approximately 20%. However, the pathogenesis and natural history of, and prognostic factors for, the condition remain poorly understood. We reported a 54-year-old female presented with cutaneous and subcutaneous metastases from atypical laryngeal carcinoid. Laryngoscopy revealed a 0.5 × 1.5-cm reddish mass on the laryngeal surface of the epiglottis. Under general anesthesia, a biopsy sample was obtained via suspension laryngoscopy. Routine pathology revealed atypical laryngeal carcinoid. Immunohistochemical staining of the sections of primary tumor was positive for cytokeratin, chromogranin A, synaptophysin, hypoxia-inducible factor-1α, P53, and CD56. GLUT-1, p-Akt, and PI3K were negative. The Ki-67 index was 15%. Supraglottic laryngectomy and selective right-neck dissection were performed. After 6 months, the patient complained of pain in the right wall of the chest; multiple cutaneous and subcutaneous nodules were evident at that site and in the abdomen. An abdominal nodule was biopsied and pathology revealed that the atypical metastatic carcinoid had metastasized to both cutaneous and subcutaneous areas of the abdomen. Chemotherapy was then prescribed. Currently, the intrathecal drug delivery system remains in place. No local recurrence has been detected. Furthermore, we systematically reviewed clinical manifestations of the disease, pathogenesis, prognostic factors, and treatment. The metastasis rate (cutaneous and subcutaneous) was approximately 12.2%. Thirty patients (62.5%) with cutaneous and subcutaneous metastases exhibited contemporaneous lymph node invasion. The 3-, 5-, and 10-year survival rates were 44.0%, 22.0%, and 13.0%, respectively. The prognosis of patients with atypical laryngeal carcinoids was poor. Relevant prognostic factors included the level of p53, human papilloma virus status, certain hypoxic markers, and distant metastasis. No optimal

    Obesity is a strong risk factor for the development and progression of sleep apnea. Responses to exercise by patients with obstructive sleep apnea syndrome (OSAS) are clinically relevant to reducing body weight and cardiovascular risk factors. This study aimed to clarify the aerobic and anaerobic exercise capacities and their possible relationships with other findings in patients with OSAS. Forty patients (30 males, 10 females) and 40 controls (30 males, 10 females) were enrolled in this study. Questionnaires (excessive daytime sleepiness, daytime tiredness, morning headache, waking unrefreshed, and imbalance), overnight polysomnography, indirect laryngoscopy, and aerobic and anaerobic exercise tests were performed. Triceps, subscapular, abdomen, and thigh skinfold thicknesses were measured. Subcutaneous abdominal fat (abdomen skinfold) was significantly higher in OSAS patients than in controls. Maximal anaerobic power and anaerobic capacity were not different significantly between the patients and controls. We found that aerobic capacity was significantly lower in OSAS patients than in controls. Aerobic capacity was negatively correlated with upper-body subcutaneous fat (triceps and subscapular skinfolds) but not correlated with subcutaneous abdominal fat in OSAS patients. In multivariate analyses using all patients, the apnea-hypopnea index remained a significant independent predictor of aerobic capacity after controlling for a variety of potential confounders including body mass index. Our data confirm that central obesity (subcutaneous abdominal fat) is prominent in patients with OSAS. Our results suggest that lower aerobic exercise capacity in patients with OSAS might be due to daily physical activity that is restricted by OSA itself. This study also suggests that the degree of subcutaneous abdominal fat cannot be used for predicting aerobic capacity level. We think that upper-body subcutaneous fat might be suitable for determining the physical fitness of

    Most cases of pneumomediastinum are caused by iatrogenic injury during surgery on the cervical region and chest or by tracheostomy. It is also well known that emphysema may occur secondary to dental treatment using an air turbine drill, but there have been few cases of emphysema extending to involve the mediastinum. Presented is a rare case in which subcutaneous emphysema and pneumomediastinum developed asymptomatically, probably due to extraction of a mandibular third molar, and were found incidentally on the day after the dental procedure. To avoid subcutaneous emphysema and pneumomediastinum associated with dental treatment and surgical intraoral procedures such as tooth extraction, air turbine drills should be used only when it is essential.

    2017-02-01

    Full Text Available Pneumoscrotum and subcutaneous emphysema make for impressive findings on examination and imaging. With ranging etiologies, thorough investigation into the source is essential to rule out potentially life threatening situations. We present a 31-year-old man with pneumoscrotum and extensive subcutaneous emphysema of his penis, abdomen, and perineum. History and physical exam didn't reveal a clear cause and he subsequently underwent surgical exploration showing no soft tissue infection. On post-operative day 1, he remained clinically stable and was discharged. Despite the usual benign nature of pneumoscrotum, full assessment is necessary to identify possible underlying conditions of significant morbidity and mortality.

    2016-01-01

    Full Text Available SUMMARY Human cysticercosis is one of the most severe parasitic infections affecting tissues. Experimental models are needed to understand the host-parasite dynamics involved throughout the course of the infection. The subcutaneous experimental model is the closest to what is observed in human cysticercosis that does not affect the central nervous system. The aim of this study was to evaluate macroscopically and microscopically the experimental subcutaneous cysticercosis caused by Taenia crassiceps cysticerci in BALB/c and C57BL/6 mice. Animals were inoculated in the dorsal subcutaneous region and macroscopic and microscopic aspects of the inflammatory process in the host-parasite interface were evaluated until 90 days after the inoculation (DAI. All the infected animals presented vesicles containing cysticerci in the inoculation site, which was translucent at 7 DAI and then remained opaque throughout the experimental days. The microscopic analysis showed granulation tissue in BALB/c mice since the acute phase of infection evolving to chronicity without cure, presenting 80% of larval stage cysticerci at 90 DAI. While C57BL/6 mice presented 67% of final stage cysticerci at 90 DAI, the parasites were surrounded by neutrophils evolving to the infection control. It is possible to conclude that the genetic features of susceptibility (BALB/c or resistance (C57BL/6 were confirmed in an experimental subcutaneous model of cysticercosis.

    Aluminium hydroxide is used as an effective adjuvant in a wide range of vaccines for enhancing immune response to the antigen. The pathogenic role of aluminium hydroxide is now recognized by the presence of chronic fatigue syndrome, macrophagic myofasciitis and subcutaneous pseudolymphoma, linked to intramuscular injection of aluminium hydroxide-containing vaccines. The aim of this study is to verify if the subcutaneous pseudolymphoma observed in this patient in the site of vaccine injection is linked to an aluminium overload. Many years after vaccination, a subcutaneous nodule was discovered in a 45-year-old woman with subcutaneous pseudolymphoma. In skin biopsy at the injection site for vaccines, aluminium (Al) deposits are assessed by Morin stain and quantification of Al is performed by Zeeman Electrothermal Atomic Absorption Spectrophotometry. Morin stain shows Al deposits in the macrophages, and Al assays (in μg/g, dry weight) were 768.10±18 for the patient compared with the two control patients, 5.61±0.59 and 9.13±0.057. Given the pathology of this patient and the high Al concentration in skin biopsy, the authors wish to draw attention when using the Al salts known to be particularly effective as adjuvants in single or repeated vaccinations. The possible release of Al may induce other pathologies ascribed to the well-known toxicity of this metal. Copyright © 2012 Elsevier GmbH. All rights reserved.

    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.

    Subcutaneous mycoses are chronic infections caused by slow growing environmental fungi. Latin American plants are used in folk medicine to treat these afflictions. Moreover, the potential of the rich Latin American biodiversity for this purpose has not been fully explored. The aim of the study was to screen Latin American plant extracts against two species of subcutaneous fungi: Sporothrix schenckii and Fonsecaea pedrosoi. One hundred ninety-five organic extracts from 151 Latin American plants were screened against two subcutaneous fungi by the agar dilution method at a concentration of 100 µg/mL, and minimum inhibitory concentrations (MICs) of active extracts were determined. Positive (amphothericin B) and negative (50% ethanol) controls were used. Twenty eight extracts showed activity at ≤100 µg/mL. Of these, four extracts from Gnaphalium gaudichaudianum DC (Asteraceae), Plumeria rubra L (Apocynaceae), Tecoma stans (L.) Juss. ex Kunth. (Bignoniaceae), and Trichostigma octandum (L.), H. Walter showed activity against F. pedrosoi at MIC 12.5 µg/mL; and, four extracts from Bourreria huanita (Lex.) Hemsl. (Boraginaceae), Phytolacca bogotensis Kunth (Phytolaccaceae), Monnina xalapensis Kunth (Polygalaceae) and Crataegus pubescens (C. Presl) C. Presl (Rosaceae) against S. schenckii. This is the first report on antifungal activity of the Latin American plants against these two subcutaneous fungi. S. schenkii and F. pedrosoi were inhibited by B. huanita (MIC: 12.5 and 25 µg/mL), G. gaudichaudianum (MIC: 50 and 12.5 µg/mL) and T. triflora (MIC: 25 µg/mL).

    Leptospirosis is a zoonosis found worldwide that is caused by a spirochete. The main reservoirs of Leptospira, which presents an asymptomatic infection, are wild rodents, including the brown rat (Rattus norvegicus). Experimental studies of the mechanisms of its renal colonization in rats have previously used an intraperitoneal inoculation route. However, knowledge of rat-rat transmission requires the use of a natural route of inoculation, such as a mucosal or subcutaneous route. We investigated for the first time the effects of subcutaneous and mucosal inoculation routes compared to the reference intraperitoneal route during Leptospira infection in adult rats. Infection characteristics were studied using Leptospira renal isolation, serology, and molecular and histological analyses. Leptospira infection was asymptomatic using each inoculation route, and caused similar antibody production regardless of renal colonization. The observed renal colonization rates were 8 out of 8 rats, 5 out of 8 rats and 1 out of 8 rats for the intraperitoneal, mucosal and subcutaneous inoculation routes, respectively. Thus, among the natural infection routes studied, mucosal inoculation was more efficient for renal colonization associated with urinary excretion than the subcutaneous route and induced a slower-progressing infection than the intraperitoneal route. These results can facilitate understanding of the infection modalities in rats, unlike the epidemiological studies conducted in wild rats. Future studies of other natural inoculation routes in rat models will increase our knowledge of rat-rat disease transmission and allow the investigation of infection kinetics. PMID:27031867

    Active electronic implants are powered by primary batteries, which induces the necessity of implant replacement after battery depletion. This causes repeated interventions in a patients' life, which bears the risk of complications and is costly. By using energy harvesting devices to power the implant, device replacements may be avoided and the device size may be reduced dramatically. Recently, several groups presented prototypes of implants powered by subcutaneous solar cells. However, data about the expected real-life power output of subcutaneously implanted solar cells was lacking so far. In this study, we report the first real-life validation data of energy harvesting by subcutaneous solar cells. Portable light measurement devices that feature solar cells (cell area = 3.6 cm 2 ) and continuously measure a subcutaneous solar cell's output power were built. The measurement devices were worn by volunteers in their daily routine in summer, autumn and winter. In addition to the measured output power, influences such as season, weather and human activity were analyzed. The obtained mean power over the whole study period was 67 µW (=19 µW cm -2 ), which is sufficient to power e.g. a cardiac pacemaker.

    Maternal obesity is a significant risk factor for development of both maternal and fetal metabolic complications. Increase in visceral fat and insulin resistance is a metabolic hallmark of pregnancy, yet not much is known how obesity alters adipose cellular function and how this may contribute to pregnancy morbidities. We sought to identify alterations in genome-wide transcription expression in both visceral (omental) and abdominal subcutaneous fat deposits in pregnancy complicated by obesity. Visceral and abdominal subcutaneous fat deposits were collected from normal weight and obese pregnant women (n = 4/group) at the time of scheduled uncomplicated cesarean section. A genome-wide expression array (Affymetrix Human Exon 1.0 st platform), validated by quantitative real-time PCR, was utilized to establish the gene transcript expression profile in both visceral and abdominal subcutaneous fat in normal weight and obese pregnant women. Global alteration in gene expression was identified in pregnancy complicated by obesity. These regions of variations led to identification of indolethylamine N-methyltransferase, tissue factor pathway inhibitor-2, and ephrin type-B receptor 6, not previously associated with fat metabolism during pregnancy. In addition, subcutaneous fat of obese pregnant women demonstrated increased coding protein transcripts associated with apoptosis as compared to lean counterparts. Global alteration of gene expression in adipose tissue may contribute to adverse pregnancy outcomes associated with obesity.

    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

    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.

    2015-01-01

    Full Text Available The primo-vascular system (PVS is a novel network identified in various animal tissues. However, the PVS in subcutaneous tissue has not been well identified. Here, we examined the putative PVS on the surface of abdominal subcutaneous tissue in rats. Hemacolor staining revealed dark blue threadlike structures consisting of nodes and vessels, which were frequently observed bundled with blood vessels. The structure was filled with various immune cells including mast cells and WBCs. In the structure, there were inner spaces (20–60 µm with low cellularity. Electron microscopy revealed a bundle structure and typical cytology common with the well-established organ surface PVS, which were different from those of the lymphatic vessel. Among several subcutaneous (sc PVS tissues identified on the rat abdominal space, the most outstanding was the scPVS aligned along the ventral midline. The distribution pattern of nodes and vessels in the scPVS closely resembled that of the conception vessel meridian and its acupoints. In conclusion, our results newly revealed that the PVS is present in the abdominal subcutaneous tissue layer and indicate that the scPVS tissues are closely correlated with acupuncture meridians. Our findings will help to characterize the PVS in the other superficial tissues and its physiological roles.

    2014-12-01

    Conclusions: Investigation into fat graft injection location indicates that there is no statistically significant difference in angiogenesis signals between the subcutaneous plane and the local fat pad in the athymic rat model. Further research should aim to continue to close the gap between clinical practice and basic scientific understanding of fat grafting.

    Chondromalacia patellae is a common cause of anterior knee pain in young patients and can be detected noninvasively with magnetic resonance imaging (MRI). The purpose of our study was to evaluate the correlation between subcutaneous fat thickness around the knee joint on axial MRIs as a surrogate marker of obesity, with the presence or absence of chondromalacia patellae.

    Fuelled by the obesity epidemic, there is considerable interest in the developmental origins of white adipose tissue (WAT) and the stem and progenitor cells from which it arises. Whereas increased visceral fat mass is associated with metabolic dysfunction, increased subcutaneous WAT is protective. There are six visceral fat depots: perirenal, gonadal, epicardial, retroperitoneal, omental and mesenteric, and it is a subject of much debate whether these have a common developmental origin and whether this differs from that for subcutaneous WAT. Here we show that all six visceral WAT depots receive a significant contribution from cells expressing Wt1 late in gestation. Conversely, no subcutaneous WAT or brown adipose tissue arises from Wt1-expressing cells. Postnatally, a subset of visceral WAT continues to arise from Wt1-expressing cells, consistent with the finding that Wt1 marks a proportion of cell populations enriched in WAT progenitors. We show that all visceral fat depots have a mesothelial layer like the visceral organs with which they are associated, and provide several lines of evidence that Wt1-expressing mesothelium can produce adipocytes. These results reveal a major ontogenetic difference between visceral and subcutaneous WAT, and pinpoint the lateral plate mesoderm as a major source of visceral WAT. They also support the notion that visceral WAT progenitors are heterogeneous, and suggest that mesothelium is a source of adipocytes.

  13. Efficacy of Subcutaneous Electrocardiogram Leads for Synchronous Timing During Chronic Counterpulsation Therapy.

    Counterpulsation devices (CPDs) require an accurate, reliable electrocardiogram (ECG) waveform for triggering inflation and deflation. Surface electrodes are for short-term use, and transvenous/epicardial leads require invasive implant procedure. A subcutaneous ECG lead configuration was developed as an alternative approach for long-term use with timing mechanical circulatory support (MCS) devices. In this study, efficacy testing was completed by simultaneously recording ECG waveforms from clinical-grade epicardial (control) and subcutaneous (test) leads in chronic ischemic heart failure calves implanted with CPD for up to 30 days. Sensitivity and specificity of CPD triggering by R-wave detection was quantified for each lead configuration. The subcutaneous leads provided 98.9% positive predictive value and 98.9% sensitivity compared to the epicardial ECG leads. Lead migration (n = 1) and fracture (n = 1) were observed in only 2 of 40 implanted leads, without adversely impacting triggering efficacy due to lead redundancy. These findings demonstrate the efficacy of subcutaneous ECG leads for long-term CPD timing and potential use as an alternative method for MCS device timing.

    The interstitial hydrostatic pressure is affecting fluid movements at microvascular level. A disturbance in the Starling equilibrium results in edema formation. The effect of venous outflow and lymphatic obstructions in human, on the interstitial fluid pressures subcutaneously and intramuscularly and the possible interaction between veins and lymphatics was studied. Utilizing a slit-catheter technique, subcutaneous tissue and intramuscular pressures were measured bilaterally in 10 patients with venous outflow obstruction and in 10 patients with lymphatic obstruction. In lymphatic obstruction the subcutaneous tissue pressure was significantly elevated as well as the intramuscular pressure, while in venous obstruction the subcutaneous tissue pressure was normal. The intramuscular pressure was significantly elevated during exercise reaching 60 mm Hg or more, combined with severe pain. Pain did not occur in patients with lymphatic obstruction. This study suggests that in lymphatic obstruction there is also an involvement of either deep lymphatics, venous dysfunction or a combination of both. Intramuscular pressures do not reach the critical level for pain during exercise. In venous obstruction mainly the intramuscular compartment is involved and interstitial pressure reaches values well above 60 mm Hg during exercise, at which level pain occurs, possibly due to tension of painreceptors in the muscle fascias.

    In previous studies, teriflunomide significantly reduced the annualised relapse rate (ARR) and disability progression. This phase 3, rater-blinded study (NCT00883337) compared teriflunomide with interferon-beta-1a (IFNβ-1a). Patients with relapsing multiple sclerosis were randomised (1:1:1) to oral teriflunomide 7-or 14 mg, or subcutaneous IFNβ-1a 44 µg. The primary composite endpoint was time to failure, defined as first occurrence of confirmed relapse or permanent treatment discontinuation for any cause. Secondary endpoints included ARR, Fatigue Impact Scale (FIS) and Treatment Satisfaction Questionnaire for Medication (TSQM). The study was completed 48 weeks after the last patient was randomised. Some 324 patients were randomised (IFNβ-1a: 104; teriflunomide 7 mg: 109; teriflunomide 14 mg: 111). No difference in time to failure was observed. There was no difference in ARR between teriflunomide 14 mg and IFNβ-1a, but ARR was significantly higher with teriflunomide 7 mg. FIS scores indicated more frequent fatigue with IFNβ-1a, though differences were only significant with teriflunomide 7 mg. TSQM scores were significantly higher with teriflunomide. There were no unexpected safety findings. Effects on time to failure were comparable between teriflunomide and IFNβ-1a. There was no difference between teriflunomide 14 mg and IFNβ-1a on ARR, though ARR was higher with teriflunomide 7 mg. The teriflunomide safety profile was consistent with previous studies.

    Full Text Available Purpose. The fate and function of the induced Schwann cells (iSCs like cells from adipose tissue have not been critically evaluated in vivo after transplantation. The objective of this study is to compare the fate of iSCs with naïve SCs (nSCs after transplantation into the lesion sites of sciatic nerve, respectively. Methods. Adipose-derived stem cells from eGFP-expressing transgenic rat’s subcutaneous fat were induced to iSCs in vitro. iSCs were injected to the sciatic nerve lesion area after crush injury and the cells fate was comparatively analyzed with that of nSCs from the same rat. Results. At 12 weeks after transplantation, nSCs were detected only in the restricted area of cell transplantation site but iSCs were widely distributed all over the sciatic nerve. Based on double fluorescence observations, both iSCs and naïve ones were colocalized with P0-expressing myelin sheath, outbound by laminin-expressing basal membrane, and terminated at contactin-associated protein-expressing doublets. However, some of iSCs were also differentiated to the fibrocyte/fibroblast-like cells. In the histological analysis of repaired sciatic nerves, axon density was higher in iSC-received group than in the nSCs group and normal sciatic nerve. Conclusion. iSCs induced from subcutaneous fat tissues have higher engraftment and migration capacity than nSCs.

    Pulmonary arterial hypertension is a life-threatening disease for which continuous intravenous prostacyclin has proven to be effective. However, this treatment requires a permanent central venous catheter with the associated risk of serious complications such as sepsis, thromboembolism, or syncope. Treprostinil, a stable prostacyclin analogue, can be administered by a continuous subcutaneous infusion, avoiding these risks. We conducted a 12-week, double-blind, placebo-controlled multicenter trial in 470 patients with pulmonary arterial hypertension, either primary or associated with connective tissue disease or congenital systemic-to-pulmonary shunts. Exercise capacity improved with treprostinil and was unchanged with placebo; the between treatment group difference in median six-minute walking distance was 16 m (p = 0.006). Improvement in exercise capacity was greater in the sicker patients and was dose-related, but independent of disease etiology. Concomitantly, treprostinil significantly improved indices of dyspnea, signs and symptoms of pulmonary hypertension, and hemodynamics. The most common side effect attributed to treprostinil was infusion site pain (85%) leading to premature discontinuation from the study in 8% of patients. Three patients in the treprostinil treatment group presented with an episode of gastrointestinal hemorrhage. We conclude that chronic subcutaneous infusion of treprostinil is an effective treatment with an acceptable safety profile in patients with pulmonary arterial hypertension.

    Full Text Available Abstract Background Bone pain in malignancy can be challenging to treat. Bisphosphonates have been found to be useful in adults with bone pain, but there are no reports of their use in children for this indication. In pediatric palliative medicine there are hurdles in translating knowledge gained primarily in adult studies into application in children. Obstacles exist in initially determining whether the evidence supports using a drug in children, and once a drug is chosen, then determining the optimal route of delivery. There is very little data to guide pediatric practitioners in this situation. Case Presentation A 9 year old boy with disseminated Ewing Sarcoma presented with extremity pain not responsive to a combination of opiates, gabapentin and non-steroidal anti-inflammatory drugs. Clodronate, a bisphosphonate, was added to the regimen to treat bone pain. It was given subcutaneously every 4 weeks with a good response and no side effects. Conclusion This case report describes the use of a bisphosphonate, clodronate, given subcutaneously to a child with Ewing sarcoma with effective relief of bone pain. It describes how the care team encountered the challenges inherent in translating adult therapy into a pediatric regimen. Furthermore the report details how a regimen was developed to address this child's concerns regarding medication administration. Further effort needs to be made at finding solutions to address the lack of good evidence for pediatric palliative therapies.

    Allergy immunotherapy (AIT) is the only available treatment that alters the natural course of allergies and has possible disease-modifying effects. AIT is administered primarily via subcutaneous injection delivered in a physician's office. Few studies have been conducted in the United States or Canada to evaluate the costs of subcutaneous immunotherapy (SCIT). To (a) describe SCIT administration processes, resources, and costs and (b) characterize the patient population receiving SCIT. A multisite, prospective, observational time and motion study was conducted. Injection and wait times were collected by a third-party observer on 1 visit for each patient. Extract preparation processes were also observed. Site staff reported on treatment protocols, administrative time, supplies, and patient medical history. Patients responded to questionnaires on demographics, reasons for treatment, medication use, productivity, and travel time. Costs were estimated by applying unit costs to the time observations and the patient- and staff-reported data. A total of 670 SCIT patients were enrolled at 6 sites in the United States and 6 sites in Canada. Average age in the United States was 41 years (SD = 18) and 44 years (15) in Canada, with 10% of the patients aged ≥ 65 years. Annual incomes were over $100,000 for 40% of U.S. patients and 30% of Canadian patients. U.S. patients had over 4 times as many different allergens in their SCIT treatments as Canadian patients, with a mean of 18 versus 4. The most common reasons reported for starting SCIT was a "desire to cure allergies once and for all" (73%) and that "symptoms are not improved by allergy medications" (60%). Percentages of patients taking allergy medications in the 4 weeks prior to observation were 86% in the United States and 66% in Canada: antihistamines 75% United States, 54% Canada; inhaled corticosteroids 32% United States, 22% Canada. The predominant comorbidity was asthma, 43% United States, 24% Canada. Site

    Computer simulation of breast anatomy is an essential component of Virtual Clinical Trials, a preclinical approach to validate breast imaging systems. Realism of breast phantoms affects simulation studies and their acceptance among researchers. Previously, we developed a simulation of tissue compartments defined by the hierarchy of Cooper's ligaments, based upon recursive partitioning using octrees. In this work, we optimize the simulation parameters to represent realistically the breast subcutaneous and retromammary tissue regions. As seen in clinical images, the subcutaneous and retromammary regions contain predominantly adipose tissue organized into relatively large compartments, as opposed to the predominantly glandular breast interior. To mimic such organization, we divided the phantom volume into "subcutaneous", "retromammary", and "interior" regions. Within each region, parameters controlling the size and orientation of tissue compartments were selected separately. In this preliminary study, we varied parameter values and calculated the corresponding average compartment volume in each region. The proposed method was evaluated using anatomic descriptors at both radiological and pathological spatial scales. We simulated the subcutaneous region as spanning 20% of the breast diameter, comparable to published analysis of breast CT images. We simulated tissue compartments with the average volume of 0.94 cm3, 0.89 cm3 and 0.31 cm3 in the subcutaneous, retromammary and interior regions, respectively. Those average volumes match within 12% the values reported from histological analysis. Future evaluation will include a comparison of simulated and clinical parenchymal descriptors. The proposed method will be extended to automate the parameter optimization, and simulate detailed spatial variation, to further improve the realism.

  8. MicroRNAome comparison between intramuscular and subcutaneous vascular stem cell adipogenesis.

    Full Text Available BACKGROUND: As an important factor affecting meat quality, intramuscular fat (IMF content is a topic of worldwide concern. Emerging evidences indicate that microRNAs play important roles in adipocyte differentiation. However, miRNAome has neither been studied during porcine intramuscular preadipocyte differentiation, nor compared with subcutaneous preadipocytes. The objectives of this study were to identify porcine miRNAs involved in adipogenesis in primary preadipocytes, and to determine whether intramuscular and subcutaneous adipocytes differ in the expression and regulation of miRNAs. RESULTS: miRNAomes in primary intramuscular and subcutaneous adipocytes during differentiation were first sequenced using the Solexa deep sequencing method. The sequences and relative expression levels of 224 known (98.2% in miRbase 18.0 and 280 potential porcine miRNAs were identified. Fifty-four of them changed in similar pattern between intramuscular vascular stem cells (IVSC and subcutaneous vascular stem cells (SVSC differentiation, such as miR-210, miR-10b and miR-99a. Expression levels of 10 miRNAs were reversely up-or down-regulated between IVSC and SVSC differentiation, 19 were up-or down-regulated only during IVSC differentiation and 55 only during SVSC differentiation. Additionally, 30 miRNAs showed fat-depot specific expression pattern (24 in cells of intramuscular origin and 6 in cells of subcutaneous origin. These adipogenesis-related miRNAs mainly functioned by targeting similar pathways in adipogenesis, obesity and syndrome. CONCLUSION: Comparison of miRNAomes in IVSC and SVSC during differentiation revealed that many different miRNAs are involved in adipogenesis, and they regulate SVSC and IVSC differentiation through similar pathways. These miRNAs may serve as biomarkers or targets for enhancing IMF content, and uncovering their function in IMF development will be of great value in the near future.

  9. Fatty acid composition of subcutaneous and visceral fat depots in New Zealand White rabbits

    Full Text Available The aim of this study was to identify the differences in the fatty acid composition of subcutaneous and visceral fat depots in healthy New Zealand White rabbits. Twelve clinically healthy rabbits with an average weight of 3.00±0.03 kg were used. The fatty acid composition of interscapular, inguinal, pericardial, perirenal and omental fat depots was determined by gas chromatography. The palmitic (C16:0 and linoleic (C18:2 acids, followed by oleic acid (C18:1 prevailed in all fat depots. The highest percentage of palmitic acid (C16:0 was detected in subcutaneous depots: inguinal (41.05±1.80% and interscapular (38.30±0.73%, whereas the highest percentage of linoleic acid (C18:2 was found in the visceral depots: perirenal (44.26±0.96% and pericardial (42.77±1.19%. Among the saturated fatty acids, myristic (C14:0 and stearic acid (C18:0 were established in higher content in subcutaneous depots than in visceral ones. Palmitoleic acid (C16:1 content in the pericardial fat depot was 10.63±2.60%, while in the interscapular, perirenal, omental and inguinal FD it was almost twice lower (Р<0.001. In the omental depot, α-linolenic acid (C18:3 content was significantly higher only vs the interscapular depot (P<0.05. The high content of saturated fatty acids in the subcutaneous depots determined their higher atherogenic and saturation index, unlike visceral ones, where a significantly higher content of unsaturated fatty acids was reported. Differences in fatty acid composition of subcutaneous and visceral fat depots proved the specific metabolism in each of them. On the other hand, this led to differences in the nutritional value of various parts of rabbit carcass.

    To evaluate the long-term outcomes of Oddi sphincter preserved cholangioplasty with hepatico-subcutaneous stoma (OSPCHS) and risk factors for recurrence in hepatolithiasis. From March 1993 to December 2012, 202 consecutive patients with hepatolithiasis underwent OSPCHS at our department. The Oddi sphincter preserved procedure consisted of common hepatic duct exploration, stone extraction, hilar bile duct plasty, establishment of subcutaneous stoma to the bile duct. Patients with recurrent stones can undergo stone extraction and/or biliary drainage via the subcutaneous stoma which can be incised under local anesthesia. The long-term results were reviewed. Cox regression model was employed to analyze the risk factors for stone recurrence. Ninety-seven (48.0%) OSPCHS patients underwent hepatic resection concomitantly. The rate of surgical complications was 10.4%. There was no perioperative death. The immediate stone clearance rate was 72.8%. Postoperative cholangioscopic lithotomy raised the clearance rate to 97.0%. With a median follow-up period of 78.5 mo (range: 2-233 mo), 24.8% of patients had recurrent stones, 2.5% had late development of cholangiocarcinoma, and the mortality rate was 5.4%. Removal of recurrent stones and/or drainage of inflammatory bile via subcutaneous stoma were conducted in 44 (21.8%) patients. The clearance rate of recurrent stones was 84.0% after subsequent choledochoscopic lithotripsy via subcutaneous stoma. Cox regression analysis showed that residual stone was an independent prognostic factor for stone recurrence. In selected patients with hepatolithiasis, OSPCHS achieves excellent long-term outcomes, and residual stone is an independent prognostic factor for stone recurrence.

    Especially in palliative care, safe and manageable administration of medication is essential. Subcutaneous drug administration is a possible alternative, when oral intake is hampered. However, evidence for this method is rare. This observational study assessed the clinical practice of subcutaneous drug administration, focusing on the evaluation of local reactions or complications to further develop recommendations. Over 14 months, patients in a specialized inpatient palliative care unit treated by the subcutaneous route were invited to participate in this clinical study. All subcutaneous medications including dosage and volume of injection, type of needles, and injection site were documented. The injection sites were systematically assessed including the subjective perceptions of patients for analysis of patient tolerability and acceptability. T-tests and Chi-squared tests of these variables were performed to calculate group differences between needles with vs. without complications (P medications were hydromorphone (59.0%), haloperidol (12.3%), and midazolam (8.3%). Complications were diagnosed most often on the third or fourth day of the needle in situ and occurred significantly more often in (fully) active patients and patients transferred or discharged at the end of treatment. The mean time of needle in situ was significantly lower (4.1 vs. 5.0 days) in complication cases than in noncomplication cases (t-test: P = 0.027). The results of this study acknowledge the clinical practice of subcutaneous administration of medication as a very flexible, broadly feasible, rather safe, and nonburdensome method. Nevertheless, this practice is not free from complications, needs appropriate nursing care, and requires standardized policies and procedures.

    Infrared thermography has become a useful tool to assess surface temperatures of animals for thermoregulatory research. However, surface temperatures are an endpoint along the body's core-shell temperature gradient. Skin and fur are the peripheral tissues most exposed to ambient thermal conditions and are known to serve as thermosensors that initiate thermoregulatory responses. Yet relatively little is known about how surface temperatures of wild mammals measured by infrared thermography relate to subcutaneous temperatures. Moreover, this relationship may differ with the degree that fur covers the body. To assess the relationship between temperatures and temperature gradients in peripheral tissues between furred and bare areas, we collected data from wild mantled howling monkeys (Alouatta palliata) in Costa Rica. We used infrared thermography to measure surface temperatures of the furred dorsum and bare facial areas of the body, recorded concurrent subcutaneous temperatures in the dorsum, and measured ambient thermal conditions via a weather station. Temperature gradients through cutaneous tissues (subcutaneous-surface temperature) and surface temperature gradients (surface-ambient temperature) were calculated. Our results indicate that there are differences in temperatures and temperature gradients in furred versus bare areas of mantled howlers. Under natural thermal conditions experienced by wild animals, the bare facial areas were warmer than temperatures in the furred dorsum, and cutaneous temperature gradients in the face were more variable than the dorsum, consistent with these bare areas acting as thermal windows. Cutaneous temperature gradients in the dorsum were more closely linked to subcutaneous temperatures, while facial temperature gradients were more heavily influenced by ambient conditions. These findings indicate that despite the insulative properties of fur, for mantled howling monkeys surface temperatures of furred areas still demonstrate a

    The standard treatment for chronic hepatitis C infected with hepatitis C virus (HCV) genotype 1 is a combination of pegylated interferon alfa and ribavirin over a 48 weeks period. It is unclear if 24 weeks treatment is possible for patients showing a rapid virological response (RVR) without compromising the sustained virological response (SVR) in Korea. Between June 2005 and September 2008, among patients chronically infected with the HCV genotype 1 who were treated with pegylated interferon alfa subcutaneously once weekly plus ribavirin based on body weight, 55 patients who had low pretreatment viral load (<600,000 IU/mL) and RVR were enrolled. A total of 55 patients were divided into 24 weeks treatment group (n=29) and the standard treatment group (n=26). The HCV RNA was quantitatively assessed before treatment, and after 12 weeks of treatment, and also qualitatively assessed after 4 weeks of treatment, at end of treatment (24 weeks), and 24 weeks after end of treatment. RVR was defined as undetectable HCV RNA at the 4 weeks of treatment. Among the 55 patients, SVR was achieved in 100% (29/29) of the patients in 24 weeks treatment and 96.2% (25/26) of the patients in the standard treatment (p=0.473). HCV genotype 1 infected patients with a low baseline HCV RNA concentration who become HCV RNA negative at week 4 may be treated for 24 weeks without compromising sustained virological response. However, an additional trial will be needed to optimize the treatment duration.

A 67-year-old African American man with no significant past medical history presented with shortness of breath and flu-like symptoms. On exam, he was noted to be profoundly hypoxemic with imaging showing diffuse thoracic changes (Figure 1 and a diffuse papular rash (Figure 2. Initial workup included coccidioidomycosis serologies which returned positive with a titer of 1:128. While exposure to coccidioidomycosis is very common in southern Arizona, dissemination is a rare occurrence. The incidence is estimated between 0.2 and 4.7 percent. Patients at highest risk include those that are immunosuppressed or that are of African or Filipino ancestry. Common extra-pulmonary sites include skin or subcutaneous tissue, meninges of brain or spinal cord, and bones. Even rarer sites include the eyes, liver, prostate, mediastinum, and kidneys. Treatment is usually the same as with pulmonary infection which is an azole agent. However, if the patient’s symptoms are severe or if the lesions involve …

    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.

    Full Text Available The intravenous (IV and subcutaneous (SC toxicity and absorption kinetics of the antileishmanial triterpene saponin PX-6518 and its active constituents maesabalide-III and -IV were studied in mice and dogs. A high-dose wash-out study of PX-6518 at 20 mg/kg SC for 5 days and a single low-dose wash-out study at 1, 2.5 or 5 mg/kg SC and IV with follow-up until day 35 after treatment were performed in mice. Beagle dogs received three escalating doses of maesabalide-III and -IV at weekly intervals (0.01, 0.1 and 0.5 mg/kg IV and maesabalide-III was also dosed SC at 0.1, 0.2 and 0.4 mg/kg. Endpoint measurements included clinical, hematological and serum biochemical parameters. Pathology and toxicokinetic studies were performed on the dogs. Whereas the neutrophils and aspartate aminotransferase and alanine aminotransferase levels were increased in the high-dose wash-out mouse study, these parameters did not change in the low-dose wash-out study. The dogs were far more susceptible than mice to liver toxicity (hepatocellular necrosis and elevated liver enzymes and developed a painful inflammatory reaction at the SC injection site. Toxicokinetic analysis revealed a non dose-linear systemic availability with plasma concentrations above the antileishmanial IC50 after only a single dose at 0.01 mg/kg IV or 0.1 mg/kg SC. Related to the long half-life (T1/2 71–91 h after SC dosing, repeated dosing at weekly intervals may result in drug accumulation and enhanced toxicity. It was decided not to pursue further drug development for PX-6518 because of the hepatotoxic risk.

    Rapid growth in infancy considerably increases the risk of obesity and metabolic disorders in adulthood especially among neonates born small. To investigate the mechanism involved, we developed an animal model of undernourishment in utero by maternal caloric restriction, in which the Z scores of body weight at weaning (19.5 days) positively correlated with parameters of obesity, metabolic disorders, and remodeling of subcutaneous adipose tissue, such as numbers of macrophages in adipose tissue, the ratio of inflammatory M1 to anti-inflammatory M2 macrophages, estimated by gene expression of specific antigens, and the relative ratio of small adipocytes less than 30 μm in diameter, on a high-fat diet at 17 weeks of age. To our knowledge, this is the first report of a possible connection between infantile body weight and adipose tissue remodeling in obesity after undernourishment in utero. PMID:23296035

    A major challenge of wildlife telemetry is choosing an attachment technique that maximizes transmitter retention while minimizing negative side effects. For waterbirds, attachment of transmitters with subcutaneous anchors has been an effective and well-established technique, having been used on >40 species. This method was recently modified to include a second subcutaneous anchor, presumably increasing transmitter retention beyond that of single-anchor attachments. This putative benefit may be offset, however, by increased health risks related to additional incisions and subcutaneous protrusions. To test this potential trade-off, we attached radiotransmitters to molting and wintering surf (Melanitta perspicillata) and white-winged scoters (M. fusca) during 2008 and 2009 in Washington State and southeast Alaska, USA, using single- (121 scoters) and double-anchor (128 scoters) attachment techniques. We estimated daily probabilities of survival and radio retention for each group, this being apparent retention for wintering scoters because we could not differentiate shed transmitters from flighted emigration. For scoters during the flightless remigial molt, we found that addition of a second anchor increased cumulative retention probability (±SE) over a 49-day period from 0.69 ± 0.11 for single-anchor to 0.88 ± 0.07 for double-anchor attachments, while having no effect on survival. However, during winter, scoters with double-anchor attachments experienced no improvement in apparent retention, while having significantly lower survival during their first 14 days following transmitter attachment; of 15 mortalities during this period, 11 had 2 subcutaneous anchors. From day 15 onward, winter survival rates were nearly identical for single- versus double-anchor attachments, indicating that adverse effects of subcutaneous anchors were mainly limited to the 14-day postattachment period. Overall, given that the survival cost of adding a second subcutaneous anchor

    Abstract Subcutaneous and submuscular anterior ulnar nerve transposition have been widely used in patients with cubital tunnel syndrome. However, the reliable evidence in favor of 1 of 2 surgical options on clinical improvement remains controversial. To maximize the value of the available literature, we performed a systematic review and meta-analysis to compare subcutaneous versus submuscular anterior ulnar nerve transposition in patients with ulnar neuropathy at the elbow. PubMed, Cochrane Library, and EMBASE databases were searched for randomized and observational studies that compared subcutaneous transposition with submuscular transposition of ulnar nerve for cubital tunnel syndrome. The primary outcome was clinically relevant improvement in function compared to the baseline. Randomized and observational studies were separately analyzed with relative risks (RRs) and 95% confidence intervals (CIs). Two randomized controlled trials (RCTs) and 7 observational studies, involving 605 patients, were included. Our meta-analysis suggested that no significant differences in the primary outcomes were observed between comparison groups, both in RCT (RR, 1.16; 95% CI 0.68–1.98; P = 0.60; I2 = 81%) and observational studies (RR, 1.01; 95% CI 0.95–1.08; P = 0.69; I2 = 0%). These findings were also consistent with all subgroup analyses for observational studies. In the secondary outcomes, the incidence of adverse events was significantly lower in subcutaneous group than in submuscular group (RR, 0.54; 95% CI 0.33–0.87; P = 0.01; I2 = 0%), whereas subcutaneous transposition failed to reveal more superiority than submuscular transposition in static two-point discrimination (MD, 0.04; 95% CI −0.18–0.25; P = 0.74; I2 = 0%). The available evidence is not adequately powered to identify the best anterior ulnar nerve transposition technique for cubital tunnel syndrome on the basis of clinical outcomes, that is, suggests that subcutaneous and

    The phase III GO-FORWARD study examined the efficacy and safety of golimumab in patients with active rheumatoid arthritis (RA) despite methotrexate therapy. Patients were randomly assigned in a 3 : 3 : 2 : 2 ratio to receive placebo injections plus methotrexate capsules (group 1, n = 133), golimumab 100 mg injections plus placebo capsules (group 2, n = 133), golimumab 50 mg injections plus methotrexate capsules (group 3, n = 89), or golimumab 100 mg injections plus methotrexate capsules (group 4, n = 89). Injections were administered subcutaneously every 4 weeks. The co-primary endpoints were the proportion of patients with 20% or greater improvement in the American College of Rheumatology criteria (ACR20) at week 14 and the change from baseline in the health assessment questionnaire-disability index (HAQ-DI) score at week 24. The proportion of patients who achieved an ACR20 response at week 14 was 33.1% in the placebo plus methotrexate group, 44.4% (p = 0.059) in the golimumab 100 mg plus placebo group, 55.1% (p = 0.001) in the golimumab 50 mg plus methotrexate group and 56.2% (p<0.001) in the golimumab 100 mg plus methotrexate group. At week 24, median improvements from baseline in HAQ-DI scores were 0.13, 0.13 (p = 0.240), 0.38 (p<0.001) and 0.50 (p<0.001), respectively. During the placebo-controlled portion of the study (to week 16), serious adverse events occurred in 2.3%, 3.8%, 5.6% and 9.0% of patients and serious infections occurred in 0.8%, 0.8%, 2.2% and 5.6%, respectively. The addition of golimumab to methotrexate in patients with active RA despite methotrexate therapy significantly reduced the signs and symptoms of RA and improved physical function.

    Tamoxifen is a selective estrogen receptor (ER) modulator which is widely used to generate inducible conditional transgenic mouse models. Activation of ER signaling plays an important role in the regulation of adipose tissue (AT) metabolism. We therefore tested the hypothesis that tamoxifen administration causes changes in AT biology in vivo. 12 weeks old male C57BL/6NTac mice were treated with either tamoxifen (n = 18) or vehicle (n = 18) for 5 consecutive days. Tamoxifen treatment effects on body composition, energy homeostasis, parameters of AT biology, glucose and lipid metabolism were investigated up to an age of 18 weeks. We found that tamoxifen treatment causes: I) significantly increased HbA{sub 1c}, triglyceride and free fatty acid serum concentrations (p < 0.01), II) browning of subcutaneous AT and increased UCP-1 expression, III) increased AT proliferation marker Ki67 mRNA expression, IV) changes in adipocyte size distribution, and V) transient body composition changes. Tamoxifen may induce changes in body composition, whole body glucose and lipid metabolism and has significant effects on AT biology, which need to be considered when using Tamoxifen as a tool to induce conditional transgenic mouse models. Our data further suggest that tamoxifen-treated wildtype mice should be characterized in parallel to experimental transgenic models to control for tamoxifen administration effects. - Highlights: • Tamoxifen treatment causes significantly increased HbA{sub 1c}, triglyceride and free fatty acid serum concentrations. • Tamoxifen induces browning of subcutaneous AT and increased UCP-1 expression. • Tamoxifen changes adipocyte size distribution, and transient body composition.

    Full Text Available The study examined the influence of weight, sex and month of hunting on the fatty acid composition of intramuscular and subcutaneous fat from 49 free ranging wild boars hunted in Lithuania during the winter season. A total number of 27 and 25 fatty acids were identified in the intramuscular fat and subcutaneous tissue of wild boars, respectively. The weight of the wild boar had mainly affected only the levels of separate fatty acids both in the intramuscular and subcutaneous fat. Higher levels of saturated fatty acids (SFA were found in the intramuscular and subcutaneous fat of males compared with females. The effect of both weight and sex on the levels of fatty acids was higher in the subcutaneous fat than in the intramuscular fat. Weight, sex and hunting month had no effect on PUFA/SFA and n-6 PUFA/n-3 PUFA ratios in the intramuscular and subcutaneous fat. The atherogenic (AI and thrombogenic (TI indexes and hypocholesterolemic/hypercholesterolemic ratio in subcutaneous fat were more favorable in females compared with males and in the January hunting season than in November and December.

    To examine the regulatory aspects of zinc-α2-glycoprotein (ZAG) association with obesity-related insulin resistance. ZAG mRNA and protein were analyzed in subcutaneous adipose tissue (AT) and circulation of lean, obese, prediabetic, and type 2 diabetic men; both subcutaneous and visceral AT were explored in lean and extremely obese. Clinical and ex vivo findings were corroborated by results of in vitro ZAG silencing experiment. Subcutaneous AT ZAG was reduced in obesity, with a trend to further decrease with prediabetes and type 2 diabetes. ZAG was 3.3-fold higher in subcutaneous than in visceral AT of lean individuals. All differences were lost in extreme obesity. Obesity-associated changes in AT were not paralleled by alterations of circulating ZAG. Subcutaneous AT ZAG correlated with adiposity, adipocyte hypertrophy, whole-body and AT insulin sensitivity, mitochondrial content, expression of GLUT4, PGC1α, and adiponectin. Subcutaneous AT ZAG and adipocyte size were the only predictors of insulin sensitivity, independent on age and BMI. Silencing ZAG resulted in reduced adiponectin, IRS1, GLUT4, and PGC1α gene expression in primary human adipocytes. ZAG in subcutaneous, but not in visceral AT, was markedly reduced in obesity. Clinical, cellular, and molecular evidence indicate that ZAG plays an important role in modulating whole-body and AT insulin sensitivity. Copyright © 2014 The Obesity Society.

    The objective of this study was to determine effects of subcutaneous (s.c.) infusions of Ca at calving day on serum concentrations of Ca, P, Mg, β-hydroxybutyrate (BHB), glucose, body condition score (BCS), milk yield, and health in fresh cows receiving a dietary cation-anion difference diet during the dry period. Three hundred seventy-five fresh Holstein cows were blocked based on parity (143 cows in first parity, 108 cows in second parity, and 124 cows in third or greater parity) and randomly assigned to 1 of 4 experimental treatments immediately after calving. Treatments were control group without infusion (control; n=190); 1 s.c. infusion of 250mL of 40% Ca borogluconate (1SC250; n=72) at calving; 1 s.c. infusion of 500mL of 40% Ca borogluconate (1SC500; n=63) at calving; 2 s.c. infusions of 250mL of 40% Ca borogluconate, one immediately after calving and the second 12 to 18h after first infusion (2SC250; n=50). Blood samples were collected immediately after parturition and at 1, 2, 4, and 7d in milk (DIM) for Ca, P, and Mg determination. Milk production, milk composition, and somatic cell count were recorded monthly up to 90 DIM. The evaluation of BCS was performed at calving and at 38 DIM. A subset of 9 cows per treatment group was randomly chosen to measure serum concentration of glucose and BHB at 2, 4, and 7 DIM. Total serum Ca in 1SC250 (8.95mg/dL), 1SC500 (9.27mg/dL), and 2SC250 (9.07mg/dL) was greater during the first week postpartum compared with control (8.45mg/dL). Serum concentrations of P, Mg, BHB, glucose, and milk yield were not affected by treatments. The dry matter intake during the first 24h after calving was higher for treatments 1SC250 (13.5kg), 1SC500 (15.0kg), and 2SC250 (15.6kg) relative to control (12.5kg). Milk somatic cell counts were lower for 1SC500 (90.5 cells/mL) and 2SC250 (82.2 cells/mL) than control (132.8 cells/mL). Risk ratio was >1 for development of metritis, and clinical and subclinical endometritis in control cows

    Splenosis is a rare condition that results from the autotransplantation of splenic parenchyma into unexpected locations such as the abdomen or subcutaneous tissue. In the presence of coexisting injury to the diaphragm intrathoracic transplantation can occur emerging as single or multiple pleural-based masses. This occurs after traumatic rupture of the spleen and is usually asymptomatic, only to be discovered incidentally on routine thoracic or abdominal imaging. To our knowledge this is the third documented case of combined intrathoracic and subcutaneous splenosis found in English literature. This occurred in a 71-year-old male involved in a motor vehicle accident at age 19 requiring urgent splenectomy. He has a significant cigarette smoking history and was referred to our hospital for further evaluation of an abnormality seen on shoulder X-ray. PMID:26236530

    Over the past several years, there has been a growing interest in the treatment method termed mesotherapy. Marketed for nonsurgical fat melting, skin rejuvenation, and hair regrowth, this technique has become increasingly popular and, in the public's view, it is considered to be a relatively benign intervention method. Mesotherapy was introduced over 50 years ago by M. Pistor, a French physician who utilized this technique initially as a novel analgesic therapeutic method for a variety of rheumatologic disorders. Since its introduction, the basic principal of locally injecting subcutaneous doses of varying chemicals has been expanded and is now utilized for the aforementioned cosmetic concerns. With its increased popularity, there has been an increase in the number of reported side effects resulting from mesotherapeutic intervention. We report multifocal scalp abscesses with subcutaneous fat necrosis as a direct result of mesotherapy; therefore, requiring extensive surgical repair.

    We compared outcomes among pediatric patients managed with minimally invasive (MI) packing techniques with those managed with traditional packing techniques for drainage of subcutaneous abscesses. After institutional review board approval, medical records of children requiring drainage of subcutaneous abscesses between January 2010 and June 2011 were reviewed. Data were collected on patient demographics, abscess location, surgical procedure, microbiology cultures, and hospital length of stay (LOS). The hospital accounting system was queried for direct and indirect costs. We compared LOS and cost data among groups managed with MI versus traditional packing techniques. Incision and drainage was performed on 329 children (57.8% girls, 72% white, mean age of 43 months [range costs decreased with the transition to the MI technique (P costs and a $385 reduction in median indirect costs (P costs and LOS in our patient population.

    Five parkinsonian patients with motor fluctuations and dyskinesia after long-term treatment with levodopa were treated with subcutaneous lisuride infusion (0.24-0.42 mg/day) together with oral levodopa for a mean period of 27 (range 13-36) months. All 5 patients showed marked initial improvement in mobility. Mild psychiatric side effects were observed in three patients; however, these side effects disappeared with reduction in the dosage of lisuride to 0.06 mg per day without a significant increase in motor fluctuations. A low dose of subcutaneous lisuride infusion with oral levodopa is an effective treatment for fluctuations of motor performance in parkinsonian patients without adverse psychiatric effects.

    2015-01-01

    Full Text Available Paratesticular leiomyosarcoma originates from testicular tunica (48%, spermatic cord (48%, epididymis (2% and dartos muscle, as well as subcutaneous tissue of the scrotum (2%. Leiomyosarcomas of the scrotum, not involving the testis, epididymis or spermatic cord, are rare, and belong to the group of subcutaneous superficial leiomyosarcomas. To the knowledge of the authors, less than 10 cases of leiomyosarcoma of the scrotum have so far been reported from India. The tumor usually presents as a painless, slow-growing scrotal mass in middle-aged or elderly men. The current approach is wide local excision, often with adjuvant therapy. The prognosis is usually good following complete excision, though a local recurrence rate of 40% has been reported. Long term follow-up is, therefore, necessary to monitor for recurrence. Herein we present the case of 35-year-old male who presented with an exophytic scrotal mass. Histopathological and immunohistochemical findings of the mass were consistent with leiomyosarcoma.

    2010-07-01

    Full Text Available Abstract Introduction Patent paraumbilical and abdominal subcutaneous veins are found frequently as collaterals in patients due to portal hypertension mainly in liver cirrhosis. Case presentation For evaluation of portal hypertension in a 72-year-old Caucasian man without liver cirrhosis, magnetic resonance imaging with gadolinium contrast-enhancement was performed and demonstrated a missing inferior vena cava. A blood return from the lower extremities was shown through enlarged collateral veins of the abdominal wall, vena azygos and hemiazygos continuation, and multiple liver veins emptying into the right cardiac atrium. We describe a rare case of abdominal subcutaneous wall veins as collaterals caused by a congenitally absent infrarenal inferior vena cava with preservation of a hypoplastic suprarenal segment. Conclusion Knowledge of these congenital variations can be of clinical importance and it is imperative for the reporting radiologist to identify these anomalies as they can have a significant impact on the clinical management of the patient.

    2016-09-01

    Full Text Available Scalp dermoid cysts are common etiologies of subcutaneous lump and bump lesions in the pediatric population, with incidence ranging from 15 to 22% (Crawford, 1990; McAvoy & Zuckerbraun, 1976. Midline scalp dermoid cysts have high risk for intracranial extension, with incidence reported to be 39–57% of cases (Wood, Couture, & David, 2012; Posnick, Bortoluzzi, Armstrong, & Drake, 1994. The following case illustrates a healthy thirteen-year-old boy who presented with asymptomatic enlarging subcutaneous posterior scalp mass who was consented for excision of the mass without pre-operative imaging, and was found to have an intracranial dermoid sinus tract intra-operatively. Post-operative imaging found an intracranial dermoid nodule which entailed an otherwise avoidable second-stage surgery to achieve complete resection.

    The autoregulation of blood flow in subcutaneous tissue was investigated at the level of the lateral malleolus by the local 133Xenon washout technique. We have investigated eight long-term insulin-dependent diabetics and seven healthy controls. All diabetics had moderate diabetic nephropathy...... and retinopathy. The blood flow remained constant in all normal subjects, when the arterial perfusion pressure was varied between 70 and 150 mm Hg. All diabetics had impaired or reduced autoregulation of the subcutaneous blood flow. The blood flow increased and decreased almost linearly with the changes...... in arterial perfusion pressure. The mechanism underlying the defect autoregulation of blood flow in diabetics is uncertain; possibilities include structural changes of the arterioles and/or alterations of local metabolic factors....

    Groener, Jan B.; Lehnhoff, Daniel; Piel, David; Nawroth, Peter P.; Schanz, Jurik; Rudofsky, Gottfried

    2013-01-01

    Summary Background: Hypothyroidism can usually be treated effectively by oral levothyroxine supplementation. There are, however, some rare circumstances, when oral levothyroxine application is not sufficient, for example malabsorption, interactions with food or other medications, or various gastrointestinal diseases. Case Report: We present a 42 year old woman with refractory and severe symptomatic hypothyroidism after subtotal thyroidectomy in spite of high dose oral levothyroxine supplementation. By stepwise increasing oral levothyroxine dosage up to 2200 micrograms plus 80 micrograms of thyronine, no sufficient substitution could be achieved. After suspicion of enteral malabsorption due to a pathological D-Xylose-test, subcutaneous levothyroxine supplementation was started. Finally, a sustained euthyroid state could be achieved. Conclusions: For selected patients who do not respond to oral treatment subcutaneous application of levothyroxine can be a suitable and effective therapy. PMID:23569562

    2017-01-01

    Full Text Available Congenital soft-tissue tumors of oral cavity are mostly hyperplastic and benign in nature. This article presents an unusual case of congenital subcutaneous hamartoma of incisive papilla in a 2-year-old female child causing feeding and breathing difficulty. Total excisional biopsy was done under local anesthesia. Histopathology of tissue in reticulin-stained slide showed the presence of immature muscle fibers whereas Masson's trichrome stain revealed collagen fibers and smooth muscles confirming the diagnosis of oral midline subcutaneous smooth muscle (leiomyomatous hamartoma of incisive papilla. It is important for dental professionals to be aware of this oral lesion present from birth mimicking overgrowth of incisive papilla, by its presentation, differential diagnosis, histopathology, and management.

    2014-07-01

    Full Text Available Subcutaneous panniculitis–like T-cell lymphoma (SPTCL, originally described as lymphoma of the cytotoxic T lymphocyte, is characterized by a tendency to infiltrate the subcutaneous tissue. The rapid clinical course and aggressive multidrug chemotherapy was the treatment of choice by many years – but it has been changed since 2008. SPTCL term is used only in relation to disease with TCRαβ phenotype, while TCRγδ+ panniculitis-like T-cell lymphomas have become classified by WHO and EORTC as primary cutaneous γδ T-cell lymphoma – PCGD-TCL. The course and prognosis of those two entities differs significantly. SPTCL occurs in children and adults.

  5. Diagnostic problems in fine needle aspiration cytology of fat necrosis within a subcutaneous lipoma

    Directory of Open Access Journals (Sweden)

    Kavishwar Vikas

    2008-01-01

    Full Text Available Fat necrosis in subcutaneous lipomas is very unusual and has been reported only occasionally. Literature regarding fine needle aspiration cytology of such a lesion is lacking although fat necrosis is well described in the breast. We came across a case of a large subcutaneous lipoma in the anterior abdominal wall with a well encapsulated area of fat necrosis. The aspiration smears showed an unusual picture which was misinterpreted as the fragments of the hydatid cyst wall. They were actually enlarged, nonnucleate, single adipocytes showing laminations, along with calcification and paucity of inflammation. Histopathology confirmed the diagnosis of fat necrosis within the lipoma. Such lesions can be mistaken on radiology for malignancy.

    The purpose of this study was to compare nebulized terbutaline 5 mg vs. subcutaneous epinephrine (1/1000, 0.3 cc) in the treatment of acute exacerbations of asthma in adult patients. Patients with a known diagnosis of asthma, who presented to the investigators in acute respiratory distress, without any previous adrenergic agents for six hours, were the subjects for this study. There were 33 patients enrolled in the study between 16 and 64 years of age. The results indicate both treatment groups gave significant increases in pulmonary function at all times when compared to baseline (p less than 0.001). Nebulized terbutaline and subcutaneous epinephrine appeared equally effective in the treatment of acute exacerbations of asthma, without significant differences in bronchodilator effectiveness or side effects.

  8. Not only for melanoma. Subcutaneous pseudoprogression in lung squamous-cell carcinoma treated with nivolumab

    Science.gov (United States)

    Sarfaty, Michal; Moore, Assaf; Dudnik, Elizabeth; Peled, Nir

    2017-01-01

    Abstract Rationale: Pseudoprogression, that is, initial tumor growth followed by subsequent tumor regression, has been well described for immunomodulation therapy in melanoma patients. This phenomenon is not well defined in lung cancer. Nivolumab, an anti-PD-1 monoclonal antibody, was recently approved for nonsmall cell lung cancer (NSCLC) as a second-line therapy. Patient concerns and diagnosis: We present a patient with squamous NSCLC, suffering from multiple bone and subcutaneous metastases. Interventions: The patient was treated with nivolumab. Outcomes: A subcutaneous lesion in her upper back grew substantially after the first cycle of nivolumab, and later regressed, with marked improvement in all cancer sites. Lessons: Such pseudoprogression may serve to predict subsequent clinical response. PMID:28121940

  9. Generalized subcutaneous edema as a rare manifestation of dermatomyositis: clinical lesson from a rare feature.

    LENUS (Irish Health Repository)

    Haroon, Muhammad

    2011-04-01

    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.

    Schulten, Véronique; Tripple, Victoria; Andersen, Kristian Aasbjerg

    2016-01-01

    BACKGROUND: Allergen-specific immunotherapy is the only curative treatment for type I allergy. It can be administered subcutaneously (SCIT) or sublingually (SLIT). The clinical efficacy of these two treatment modalities appears to be similar, but potential differences in the immunological...... mechanisms involved have not been fully explored. OBJECTIVE: To compare changes in the allergen-specific T cell response induced by subcutaneous versus sublingual administration of allergen-specific immunotherapy (AIT). METHODS: Grass pollen allergic patients were randomized into groups receiving either SCIT...... was observed starting 10 months after treatment was commenced. At 24 months, T cell responses showed IL-5 levels significantly below the before treatment baseline. No significant reduction of IL-5 was observed in the SLIT or untreated group.

  11. Visfatin mRNA expression in human subcutaneous adipose tissue is regulated by exercise

    DEFF Research Database (Denmark)

    Frydelund-Larsen, Lone; Åkerström, Thorbjörn; Nielsen, Søren

    2006-01-01

    Visfatin [pre-beta-cell colony-enhancing factor (PBEF)] is a novel adipokine that is produced by adipose tissue, skeletal muscle, and liver and has insulin-mimetic actions. Regular exercise enhances insulin sensitivity. In the present study, we therefore examined visfatin mRNA expression...... by elevated levels of plasma visfatin. Recombinant human IL-6 infusion to mimic the exercise-induced IL-6 response (n = 6) had no effect on visfatin mRNA expression in adipose tissue compared with the effect of placebo infusion (n = 6). The finding that exercise enhances subcutaneous adipose tissue visfatin mRNA...... in abdominal subcutaneous adipose tissue and skeletal muscle biopsies obtained from healthy young men at time points 0, 3, 4.5, 6, 9, and 24 h in relation to either 3 h of ergometer cycle exercise at 60% of Vo(2 max) or rest. Adipose tissue visfatin mRNA expression increased threefold at the time points 3, 4...

    Full Text Available This study was performed from February to April 2006; several visits were made to abattoirs in the north of Iran for Hypoderma spp infestation. Necropsy inspection of slaughtered and skinned animals were carried out by examination of the inner skin surface and subcutaneous tissues. Warbles were isolated by squeezing nodules from subcutaneous tissues. In the case of abscess presence, aseptic sample were taken from abscesses. The parasitological and bacteriological examinations were performed on the samples. The results indicated that 104 out of 958 of slaughtered animals were infested to Hypoderma spp in which 48 (46.15 %, 34 (32.69 % and 22 (21.15 % were infested to Hypoderma bovis, Hypoderma lineatum and both species, respectively. Following bacterial analysis, the following bacteria were isolated: Escherichia coli, Streptococcus pyogenes, Staphylococcus aureus, Staphylococcus epidermidis and Klebsiella pneumonia.

    Tan, Rommel Max; Singh, Kuldeep; Sandman, Kristi

    2013-04-01

    An 8-year-old, female domestic shorthair cat was presented with a ventral abdominal subcutaneous mass. A radiograph showed that the center of the mass contained what appeared to be steel sutures, presumed to be from an ovariohysterectomy performed 7 years earlier. The excised mass was irregular and contained numerous pockets filled with friable necrotic material and hemorrhages that were dissected by fibrous connective tissue bands. Multiple tangled and fragmented pieces of steel staples were deeply embedded within the mass. Histologically, the mass was non-encapsulated, densely cellular, and infiltrative. Neoplastic cells lined caverns and channels and were factor VIII-positive by immunohistochemistry. The neoplastic cells were oval to round with granular cytoplasm and vesicular nucleus and exhibited moderate cellular and nuclear pleomorphism. A diagnosis of subcutaneous hemangiosarcoma was made. To our knowledge, this is the first report of foreign body associated hemangiosarcoma and the first case of steel staple associated neoplasm in domestic animals.

    This short communication describes the phylogenetic analysis of 48 Dirofilaria worms isolated from human patients in Ukraine. 102 cases were both of subcutaneous (47; 46.1%) and ocular (54; 52.9%) locations. Worms from 44 patients (15 subcutaneous and 29 ocular) were subjected to DNA extraction and amplification of a specific fragment of the 12S rRNA subunit, and sequences were used for phylogenetic analysis. Results showed that 13.8% of the ocular cases analyzed at molecular level were caused by Dirofilaria immitis. Very few cases of ocular human dirofilariosis due to D. immitis have been described in the literature to date, majority of them attributed to Dirofilaria repens. Our results show that ocular dirofilariosis cannot be excluded in areas of low endemicity for D. repens were D. immitis is also present. Copyright © 2014 Elsevier B.V. All rights reserved.

    2016-01-01

    BACKGROUND: After a subcutaneous injection fluid might leak out of the skin, commonly referred to as leakage or backflow. The objective was to examine the influence of needle design and injection technique on leakage after injections in the subcutaneous tissue of humans and pigs. METHOD: Leakage...... data were obtained from a post hoc analysis of clinical trial data and from a pig study. Data from the clinical study were used to determine leakage as a function of injection volume, speed and region. Data from the pig study were used to determine leakage as a function of needle wall thickness, needle...... taper, injection angle, and wait time from end of injection to withdrawal of needle from skin. RESULTS: Leakage volume was positively related to injection volume. Injections in the abdomen caused less leakage than thigh injections. A 32G needle caused less leakage than a 31G and a 32G tip (tapered...

  16. CUBITAL TUNNEL SYNDROME: REVIEW OF 14 ANTERIOR SUBCUTANEOUS TRANSPOSITIONS OF THE VASCULARIZED ULNAR NERVE

    Directory of Open Access Journals (Sweden)

    2005-06-01

    Full Text Available Anterior transposition of the ulnar nerve is widely implemented for treatment of cubital tunnel ‎syndrome. However, preservation of the extrinsic blood supply of the ‎ulnar nerve may result in better clinical outcomes. Fourteen patients with cubital tunnel ‎syndrome, 11 ‎men and 3 women, were treated by anterior subcutaneous transposition of the ulnar nerve. The extrinsic blood supply of the ulnar nerve was ‎preserved. The average age at the time of operation was 33 years. The average follow-up period was 44 months. Post-operative outcome assessment by an independent examiner was based on the modified Bishop rating system. Nine patients had excellent or good outcomes. Five patients had a fair outcome. There ‎were no complications or recurrence of symptoms. Anterior subcutaneous ‎transposition of the vascularized ulnar nerve is an effective method of surgical ‎treatment for patients with cubital tunnel syndrome.

    The search for effective treatments for obesity and its comorbidities is of prime importance. We previously identified IKK-ε and TBK1 as promising therapeutic targets for the treatment of obesity and associated insulin resistance. Here we show that acute inhibition of IKK-ε and TBK1 with amlexanox treatment increases cAMP levels in subcutaneous adipose depots of obese mice, promoting the synthesis and secretion of the cytokine IL-6 from adipocytes and preadipocytes, but not from macrophages. IL-6, in turn, stimulates the phosphorylation of hepatic Stat3 to suppress expression of genes involved in gluconeogenesis, in the process improving glucose handling in obese mice. Preliminary data in a small cohort of obese patients show a similar association. These data support an important role for a subcutaneous adipose tissue-liver axis in mediating the acute metabolic benefits of amlexanox on glucose metabolism, and point to a new therapeutic pathway for type 2 diabetes.

    Perivascular epithelioid cell neoplasms (PEComas) are a group of mesenchymal tumours with concurrent melanocytic and myogenic differentiation. Although many cases are sporadic, PEComas can be associated with tuberous sclerosis. A distinct subset of deep-seated PEComas has been shown to carry TFE3 fusions. To our knowledge, this is the first reported case of primary subcutaneous malignant PEComa with molecular confirmation of TFE3 gene rearrangement. © 2015 British Association of Dermatologists.

    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.

    Activity in both muscle spindle endings and cutaneous stretch receptors contributes to the sensation of joint movement. The present experiments assessed whether muscle pain and subcutaneous pain distort proprioception in humans. The ability to detect the direction of passive movements at the interphalangeal joint of the thumb was measured when pain was induced experimentally in four sites: the flexor pollicis longus (FPL), the subcutaneous tissue overlying this muscle, the flexor carpi radialis (FCR) muscle and the subcutaneous tissue distal to the metacarpophalangeal joint of thumb. Tests were conducted when pain was at a similar subjective intensity. There was no significant difference in the ability to detect flexion or extension under any painful or non-painful condition. The detection of movement was significantly impaired when pain was induced in the FPL muscle, but pain in the FCR, a nearby muscle that does not act on the thumb, had no effect. Subcutaneous pain also significantly impaired movement detection when initiated in skin overlying the thumb, but not in skin overlying the FPL muscle in the forearm. These findings suggest that while both muscle and skin pain can disturb the detection of the direction of movement, the impairment is site-specific and involves regions and tissues that have a proprioceptive role at the joint. Also, pain induced in FPL did not significantly increase the perceived size of the thumb. Proprioceptive mechanisms signalling perceived body size are less disturbed by a relevant muscle nociceptive input than those subserving movement detection. The results highlight the complex relationship between nociceptive inputs and their influence on proprioception and motor control.

    Prior studies have demonstrated the effectiveness of noninvasive transdermal insulin delivery using a cymbal transducer array. In this study the physiologic response to ultrasound mediated transdermal insulin delivery is compared to that of subcutaneously administered insulin. Anesthetized rats (350-550 g) were divided into four groups of four animals; one group representing ultrasound mediated insulin delivery and three representing subcutaneously administered insulin (0.15, 0.20, and 0.25 U/kg). The cymbal array was operated for 60 minutes at 20 kHz with 100 mW/cm2 spatial-peak temporal-peak intensity and a 20% duty cycle. The blood glucose level was determined at the beginning of the experiment and, following insulin administration, every 15 minutes for 90 minutes for both the ultrasound and injection groups. The change in blood glucose from baseline was compared between groups. When administered by subcutaneous injection at insulin doses of 0.15 and 0.20 U/kg, there was little change in the blood glucose levels over the 90 minute experiment. Following subcutaneous administration of insulin at a dose of 0.25 U/kg, blood glucose decreased by 190±96 mg/dl (mean±SD) at 90 minutes. The change in blood glucose following ultrasound mediated insulin delivery was -262±40 mg/dl at 90 minutes. As expected, the magnitude of change in blood glucose between the three injection groups was dependant on the dose of insulin administered. The change in blood glucose in the ultrasound group was greater than that observed in the injection groups suggesting that a higher effective dose of insulin was delivered.

    The contribution is a case report on massive, subcutaneous metastatic spreading of a malignant melanoma. Ten months after excision of a malignant melanoma, the truncus of the 51 year-old male patient showed multiple hematomas sized from 1-3 cm{sup 2}, located above cutaneous/subcutaneous lumps of which some were painful and non-displaceable. The examinations for detection of meatastes as well had shon an unusual picture in that there was no spreading to the lungs. CT scans revealed subcutaneous filiae to an extent unseen before. This final diagnosis is all the more of high interest as an initial diagnosis falsely interpreted this metastatic spreading pattern to be a hemorrhagic diathesis. Together with the unusual non-spreading to the lungs, this case of subcutaneous formation of metastases indicates that in staging examinations of melanoma patients, such rare patterns of metastatic spreading should be taken into account. (orig./CB) [Deutsch] Es wird ueber den Fall einer massiven subkutanen Metastasierung eines malignen Melanoms berichtet. Zehn Monate nach der Exzision eines malignen Melanoms zeigten sich bei dem 51jaehrigen maennlichen Patienten am Stamm multiple 1-3 cm{sup 2} grosse flaechige Haematome ueber kutanen/subkutanen, teils schmerzhaften und nicht verschieblichen Knoten. Auffallend war, dass auch im Verlauf keine intrapulmonalen Absiedlungen gefunden wurden. Interessant ist die Darstellung der subkutanen Filiae im Computertomogramm, die wir so massiv noch nicht gesehen haben. Da die Metastasierung zuerst als haemorrhagische Diathese fehldiagnostiziert wurde, scheint die Diagnose einer subkutanen Aussaat eines malignen Melanoms um so interessanter. Der zusaetzlich zur subkutanen Metastasierung fehlende Lungenbefall zeigt, dass bei Staginguntersuchungen von Melanompatienten ein Metastasierungstyp vorliegen kann, welcher erheblich von gaengigen Metastasierungsmodellen abweichen kann.

    Chondromalacia patellae is a common cause of anterior knee pain in young patients and can be detected noninvasively with magnetic resonance imaging (MRI). The purpose of our study was to evaluate the correlation between subcutaneous fat thickness around the knee joint on axial MRIs as a surrogate marker of obesity, with the presence or absence of chondromalacia patellae. A retrospective review was conducted of knee MRIs in 170 patients who satisfied the inclusion criteria. Imaging was performed over a 12-month period on a 1.5T MRI system with a dedicated extremity coil. Two radiologists experienced in musculoskeletal imaging assessed each examination in consensus for the presence or absence of chondromalacia patellae and graded positive studies from 0 (absent) to 3 (full cartilage thickness defect). Measurement of subcutaneous knee fat thickness was obtained on the medial aspect of the knee. MRI findings of chondromalacia patellae were present in 33 patients (19.4%), of which, there were 11 grade 1 lesions (33.3%), 9 grade 2 lesions (27.3%), and 13 grade 3 lesions (39.4%). The mean subcutaneous knee fat thickness was significantly higher in the chondromalacia patellae group for all grades compared with the normal group (P chondromalacia patellae (R = 0.48 [95% confidence interval, 0.38-0.68]; P chondromalacia patellae. Subcutaneous knee fat thickness as a surrogate marker of obesity was positively associated with the presence and severity of chondromalacia patellae on MRI.

    To evaluate the biocompatibility and local sensibility reaction to bacterial cellulose hydrogel (0.8%) implanted in subcutaneous tissue of rabbits. Fifteen New Zeland rabbits were randomly allocated into three groups: T1, 7 days, T2, 21 days, and T3, 84 days. The new material was implanted in the subcutaneous tissue of the ear; on the scalp over the periosteum; and on the outer and inner surfaces of the thighs, in the aponeurosis of the muscle. At 7, 21 and 84 postoperative days, the material was collected for histological study. The clinical signs, inflammatory response, angiogenesis and fibrogenesis were variables used for analysis of the biocompatibility and biological reactivity to BCH. Analyses were performed with an AXIO(r) Imager. The statistical tests were performed using the GraphPad Prism 5.0 program(r) The intensity of the inflammatory infiltrate, considering the different cell types (PMN, LMN and GC), was statistically significant, with group T1 different from groups T2 and T3 (p = 0.0124 and p <0.0001, respectively) and T2 different from the T3 group (p = 0.0007). Fibrogenesis grade 1 was the most prevalent in groups T1 (55.4%) and T2 (44.6%). The formation of neovascularization in the group was identified in 84.4% of samples. Bacterial cellulose hydrogel (0.8%) is biocompatible, integrating with the subcutaneous tissue of rabbits and inducing tissue remodeling.

    To evaluate the results from subcutaneous anterior transposition of the cubital nerve for treating cubital tunnel syndrome (CTS) and the influence of prognostic factors such as preoperative McGowan stage, age and duration of symptoms. 36 patients with CTS who underwent subcutaneous anterior transposition of the cubital nerve between 2006 and 2009 were evaluated after an average follow-up of 28 months. Their mean age was 41.6 years. Nine patients were in McGowan stage I, 18 in stage II and nine in stage III. There was a statistically significant improvement in sensory and motor deficits. 78% of the patients with severe neuropathy improved after surgery. According to the modified Bishop score, 21 patients (58.3%) had excellent results, seven (19.4%) good, six (16.7%) satisfactory and two (5.55%) poor. The satisfaction rate was 86% and 72% of the patients recovered their daily activities without limitations. The severity of neuropathy and preoperative duration of symptoms, but not age, had a negative influence on the outcome. The subcutaneous anterior transposition of the cubital nerve is safe and effective for treating CTS of different degrees of severity. Given the major prognostic factors identified, surgical treatment should be advised as soon as axonal loss has become clinically evident.

    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 Background: Spontaneous pneumomediastinum (SPM and subcutaneous emphysema are rare findings in children. Various etiologies have been reported for SPM, such as foreign body aspiration in infants, especially in those aged less than three years. In addition to the complications associated with foreign body aspiration, SPM may also become a life-threatening condition if left untreated. In the present report, we discussed a case of subcutaneous emphysema, pneumothorax, and pneumomediastinum in a 13-month-old infant previously treated for pneumonia.Case report: The infant was initially presented with subcutaneous emphysema of the neck, without respiratory distress following pneumonia. In the chest radiography, mediastinal shift and possible pneumothorax were reported, and a chest tube was inserted as the respiratory condition deteriorated. Emergency bronchoscopy showed a foreign body logged in the left respiratory tract, which was removed. Three days later, the chest tube was detached, and the patient was discharged in healthy conditions within the next two days.Conclusion: Pediatricians constantly need to consider the risk of foreign body aspiration, particularly in the presence of respiratory complications, such as SPM, even in the infants with an unreliable history of foreign body aspiration

    Neurofibromatosis type 1 (NF-1) is an autosomal dominant disorder that has three major features: multiple neural tumors, cafe-au-lait spots, and pigmented iris hamartomas (Lisch nodules). The purpose of this case report is to advise physicians of the danger associated with the progression of fast-onset massive hemorrhage to hemodynamic instability, which mandates rapid treatment to prevent the development of a life-threatening condition. A 64-yr-old woman with NF-1 was admitted to the Emergency Department (ED) because of a rapidly growing, 10 x 5 x 3 cm-sized mass on the left back area. She had previously undergone surgery for a large subcutaneous hematoma, which had developed on her right back area 30 yr before. She became hemodynamically unstable with hypotension during the next 3 hr after admission to ED. Resuscitation and blood transfusion were done, and the hematoma was surgically removed. The mass presented as a subcutaneous, massive hematoma with pathologic findings of neurofibroma. We report a case of NF-1 that presented as recurrent, massive, subcutaneous hemorrhage on the back region combined with hypovolemic shock.

    The demonstration of severe complications in patients implanted with a transvenous implantable cardioverter defibrillator (ICD) has led to the development of devices equipped with a subcutaneous lead. This new technique offers numerous advantages but also certain disadvantages. Various studies or anecdotal clinical cases have specifically been conducted with this subcutaneous defibrillation system in children and/or patients with congenital heart disease. Results of these studies suggest: 1) a high feasibility despite being limited by a selection process that excludes patients requiring permanent pacing and patients declared ineligible during pre-screening; 2) good efficacy of electrical shocks in reducing induced or spontaneous ventricular arrhythmias; 3) in this specific subset of patients, 2 types of complications have been particularly described: a risk of device exteriorization and infection, and a large number of inappropriate therapies primarily related to T-wave oversensing. The subcutaneous ICD could therefore constitute the gold standard for patients with complex congenital heart disease with no venous access to the heart or with a persistent shunt increasing the risk of systemic emboli as well as in young patients with channelopathy or hypertrophic cardiomyopathy not requiring long-term pacing. Technological change (reduction in device size, better differentiation between R- and T-waves, possibility of pacing if device coupled with a leadless pacemaker) could reduce the limitations and complications and thereby increase the indications in this sub-group of patients.

    Laparoscopic adjustable gastric band access port has been routinely sutured to the anterior fascia of the abdominal wall using nonabsorbable sutures. We present our technique demonstrating that nonfascial fixation with using a mesh allows for a safe and durable placement of the port in the superficial subcutaneous tissue. Retrospective chart review included 102 consecutive patients who had Lap band surgery performed by single surgeon (EA) from June 2011 until April 2013. The port was sutured to a piece of polypropylene mesh and tunneled in the subcutaneous tissue away from the incision. Patients' demographics were analyzed as well as the following parameters: OR time for port placement, follow-up, port complications requiring revision, difficult access facilitated by fluoroscopy imaging, port infection, and skin erosion. The study included 102 consecutive patients (23 males and 79 females), mean age was 49 years old, mean weight was 284.7 lb, mean height was 66.2 in., and mean body mass index (BMI) was 46.3 kg/m(2). The average operative time for port placement was 4 min, mean follow-up was 12 months, port complications occurred in 2 % of the patients while fluoroscopy for difficult port access was required in 3 %. No cases of port infections or skin erosions occurred. Superficial subcutaneous placement of Lap Band Port using mesh fixation without anchoring the port to the fascia provides safe and durable access. Deep incisions to secure the port directly to the fascia might not be necessary.

    Multiple sclerosis (MS) is the main nontraumatic cause of handicap in young adults. Immunomodulators and treatments limiting lymphocyte migration have been proven efficient to treat relapsing-remitting MS. Subcutaneous IFN-β1a improve relapse rate and MRI parameters in a series of double-blind, placebo-controlled trials in relapsing-remitting MS patients. Similar results, and with a greater extent, were obtained when treating patients with a first demyelinating event suggestive of MS. Except for the rare liver toxicity, the drug is well tolerated and has no severe adverse reaction. When compared with intramuscular IFN-β1a, both relapse rate and MRI parameters were modulated in favor of the subcutaneous administration. Although the effect of subcutaneous IFN-β1a on disability progression is limited, the good tolerance profile together with the efficiency of the drug explain why this treatment, as well as the other interferons and glatiramer acetate, is a first-line therapy for relapsing-remitting MS.

    Interferon-alfa is used in the treatment of primary cutaneous B-cell lymphoma (PCBCL). Therapy with interferon-alfa has thus far been reported solely in case reports and small case series, mostly describing intralesional use. We sought to evaluate efficacy, response rate, time to response, duration of response, and safety of subcutaneously administered interferon-alfa for the treatment of cutaneous B-cell lymphoma. We conducted a retrospective chart analysis of patients given the diagnosis of PCBCL and treated with interferon-alfa subcutaneously at a tertiary referral center. Fifteen patients with indolent subtypes of PCBCL were identified. The overall response rate was 66.7%; all responding patients went into complete remission. Response was not significantly associated with the maximum tolerated dose. Within the median follow-up time of 40 months, 90% of the responders experienced a relapse; median duration of response was 15.5 months. Adverse events were predominantly mild and in no case led to cessation of therapy. Retrospective nature of the analysis and small number of patients because of scarcity of the disease are limitations. Treatment of indolent PCBCL with subcutaneously injected interferon-alfa demonstrated good response rates and tolerability. Response was not dose dependent. Relapses were observed in nearly all responding patients raising the question of interferon-alfa maintenance therapy in PCBCL. Copyright © 2013 American Academy of Dermatology, Inc.

    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.

    Large subcutaneous fat cells associate with insulin resistance and high risk of developing type 2 diabetes. We investigated if changes in fat cell volume and fat mass correlate with improvements in the metabolic risk profile after bariatric surgery in obese patients. Fat cell volume and number were measured in abdominal subcutaneous adipose tissue in 62 obese women before and 2 years after Roux-en-Y gastric bypass (RYGB). Regional body fat mass by dual-energy X-ray absorptiometry; insulin sensitivity by hyperinsulinemic-euglycemic clamp; and plasma glucose, insulin, and lipid profile were assessed. RYGB decreased body weight by 33%, which was accompanied by decreased adipocyte volume but not number. Fat mass in the measured regions decreased and all metabolic parameters were improved after RYGB (P fat cell size correlated strongly with improved insulin sensitivity (P = 0.0057), regional changes in fat mass did not, except for a weak correlation between changes in visceral fat mass and insulin sensitivity and triglycerides. The curve-linear relationship between fat cell size and fat mass was altered after weight loss (P = 0.03). After bariatric surgery in obese women, a reduction in subcutaneous fat cell volume associates more strongly with improvement of insulin sensitivity than fat mass reduction per se. An altered relationship between adipocyte size and fat mass may be important for improving insulin sensitivity after weight loss. Fat cell size reduction could constitute a target to improve insulin sensitivity. © 2014 by the American Diabetes Association.

    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.

    Maternal smoking during pregnancy increases the risk of obesity in the offspring. Not much is known about the associations with other measures of body composition. We assessed the associations of maternal smoking during pregnancy with the development of subcutaneous fat mass measured as peripheral and central skinfold thickness measurements in early childhood, in a population-based prospective cohort study from early fetal life onward in the city of Rotterdam, The Netherlands. The study was performed in 907 mothers and their children at the ages of 1.5, 6 and 24 months. As compared to non-smoking mothers, mothers who continued smoking during pregnancy were more likely to have a younger age and a lower educational level. Their children had a lower birth weight, higher risk of small size for gestational age and were breastfed for a shorter duration (P-values smoking mothers, mothers who smoked in first trimester only and mothers who continued smoking during pregnancy (P > 0.05). Also, the reported number of cigarettes smoked by mothers in both first and third trimester of pregnancy were not associated with peripheral, central and total subcutaneous fat mass in the offspring at the ages of 1.5, 6 and 24 months. Our findings suggest that fetal exposure to cigarette smoke during pregnancy does not influence subcutaneous fat mass in early childhood. Follow-up studies are needed in children at older ages and to identify associations of maternal smoking during pregnancy with other measures of body composition.

    Programmed subcutaneous insulin infusion is a promising method for normalisation of the blood glucose concentration in insulin-dependent diabetics. To evaluate insulin availability the absorption rate from the depot is usually measured intermittently by radioactively-labelled insulin and stationary scintillation detectors. Small portable detectors are an alternative, however, and continuous absorption measurements could be made during normal life conditions. Contrary to conventional single injection therapy, the insulin depot initially expands during infusion treatment, changing the geometry during measurements. In the present study the methodological aspects and geometrical dependences were investigated. Simulated studies were made with various plane disc 125I sources in Perspex phantoms as well as 125I-insulin absorption studies in short-term subcutaneous infusion experiments with anaesthetised rabbits. Results from portable, end-window Geiger-Müller (GM) detectors fixed above the depots and close to the surfaces of phantom or skin were compared with results obtained by a conventional stationary NaI(Tl) detector 15 cm from the phantom or skin surface. With a 125I-insulin infusion site at 5 mm depth in the subcutaneous tissue of rabbits, an overall linear proportionality was found between the results obtained with a NaI(Tl) detector and a GM detector raised 15 mm above the skin surface inside the detector housing.

    Nineteen children who presented for treatment of acute asthma symptoms were studied. They were randomized to receive either subcutaneous epinephrine 0.01 mg/kg (0.3 mg maximum) or nebulized terbutaline 1 mg in 2 mL normal saline. The drugs were administered using the double-blind method. Each patient received either subcutaneous epinephrine with concurrent nebulized normal saline or nebulized terbutaline with a concurrent subcutaneous injection of normal saline. Depending on the patient's clinical status, up to three doses of the same drug and placebo were administered. Pulmonary functions (FEV1, FVC, FEF25-75), heart rate, respiratory rate, and pulmonary index were obtained before treatment, at 20 minutes, and at one hour after the final treatment. Except for the baseline respiratory rate, the mean number of treatments, pulmonary index, heart rate, and respiratory rate (at 20 minutes and one hour) were not statistically different. Pulmonary functions were not significantly different at any time. The one-hour post-treatment pulmonary functions (percentage of predicted normal) for terbutaline and epinephrine were FEV1, 49.2 +/- 18.4% and 49.4 +/- 16.9%; FVC, 72.7 +/- 23.4% and 62.7 +/- 21.6%; and FEF25-75, 31.8 +/- 18.6% and 39.0 +/- 12.2%, respectively. The data presented support our hypothesis that terbutaline by nebulization is at least as effective as epinephrine in the management of children with similar degrees of pulmonary obstruction.

    Full Text Available Objective: Lymphoedema involves swelling, especially in the subcutaneous tissues. For lymphoedema management to be successful, it is necessary to remove the interstitial fluid. Subcutaneous echogenicity may be associated with interstitial fluid, but echogenicity is not an indicator for the evaluation of management because we do not directly compare echogenicity with the interstitial fluid. We aimed to identify an outcome indicator for the evaluation of interstitial fluid using ultrasonography. We assessed the correlation between echogenicity and transverse relaxation rate (R2 on magnetic resonance imaging. Methods: This was an observational study. Healthy adults with leg swelling after activity for >8 h were recruited. The legs of 13 women were evaluated using ultrasonography, magnetic resonance imaging and measurements of the limb circumference before and after an intervention to reduce the swelling. Results: Echogenicity in the oedema group was greater than that of the controls. Echogenicity decreased with reductions in oedema. The range of the strongest correlations with the changes in R2 occurred at echogenicity values of 48–144 (Pearson’s correlation coefficient: r = −0.63 and p < 0.01. Thus, it was possible to evaluate the interstitial fluid using echogenicity. Conclusion: The outcome indicators for the evaluation of interstitial fluid using ultrasonography were echogenicities in the range of 48–144, and these values were valid for assessing the interstitial fluid in the subcutaneous tissue.

    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.

    To develop an automatic segmentation algorithm to classify abdominal adipose tissues into visceral fat (VAT), deep (DSAT), and superficial (SSAT) subcutaneous fat compartments and evaluate its performance against manual segmentation. Data were acquired from 44 normal (BMI 18.0-22.9 kg/m(2) ) and 38 overweight (BMI 23.0-29.9 kg/m(2) ) subjects at 3T using a two-point Dixon sequence. A fully automatic segmentation algorithm was developed to segment the fat depots. The first part of the segmentation used graph cuts to separate the subcutaneous and visceral adipose tissues and the second step employed a modified level sets approach to classify deep and superficial subcutaneous tissues. The algorithmic results of segmentation were validated against the ground truth generated by manual segmentation. The proposed algorithm showed good performance with Dice similarity indices of VAT/DSAT/SSAT: 0.92/0.82/0.88 against the ground truth. The study of the fat distribution showed that there is a steady increase in the proportion of DSAT and a decrease in the proportion of SSAT with increasing obesity. The presented technique provides an accurate approach for the segmentation and quantification of abdominal fat depots. © 2014 Wiley Periodicals, Inc.
