A Pilot Study of Adolescent and Young Adult Experience with Subcutaneous Depot Medroxyprogesterone Acetate.

STUDY OBJECTIVE: To describe satisfaction with and preference for subcutaneous depot medroxyprogesterone acetate (DMPA-SC), along with adherence and feasibility, in adolescents and young adults (AYAs) METHODS: Survey of a sample of AYA patients who received DMPA-SC prescription and injection RESULTS: Of 108 eligible patients, 34 completed the survey, and 29 respondents received at least 1 DMPA-SC injection. The mean age was 16.9 years. Seventy-nine point three percent used it for gynecologic reasons, 27.6% for gender dysphoria, and 20.7% for contraception (multiple responses allowed); 93.1% were satisfied with DMPA-SC; 78.6% gave DMPA-SC on time; 88.9% reported that giving the injection was easy; 89.7% reported no problems with administration; 89.3% reported no problems obtaining DMPA-SC; and 76.9% plan to continue using DMPA-SC. CONCLUSION: In this small sample of patients within a children's hospital, the overall experience with DMPA-SC was favorable. Clinicians caring for adolescents should consider including DMPA-SC in counseling when depot medroxyprogesterone acetate (DMPA) is indicated.

Effect of a reused insulin needle remaining in a patient's body.

Diabetes is one of the most common chronic diseases at present, and insulin pen injection therapy plays an important role in the treatment of diabetes. However, the majority of patients might reuse disposable insulin pen needles for various reasons, which leads to related complications. As far as we know, this article is the first to describe a patient whose needle remained in the right upper limb while reusing a disposable insulin injection needle for subcutaneous insulin injection with the non-dominant hand. The patient went to the doctor 1 week later. The needle moved from the lateral area of the proximal upper arm (the injection site) to the posterolateral area of the distal upper arm. The needle was then successfully removed by surgery. The reuse of disposable insulin pen needles might lead to serious complications. It is suggested to strengthen the education of people living with diabetes to help them use insulin pen needles safely.

Real-World Analysis of Therapeutic Outcome in Type 1 Diabetes Mellitus at a Tertiary Care Center.

Insulin replacement in type 1 diabetes mellitus (T1DM) needs intensified treatment, which can either be performed by multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII). This retrospective analysis of a real-world scenario aimed to evaluate whether glycaemic and cardiovascular risk factors could be controlled with CSII outclass MDI as suggested by recent evidence. Data from patients with either insulin pump (n=68) or injection (n=224) therapy at an Austrian tertiary care centre were analysed between January 2016 and December 2017. There were no significant differences with regard to the latest glycosylated hemoglobin, cardiovascular risk factor control or diabetes-associated late complications. Hypoglycaemia was less frequent (P<0.001), sensor-augmented therapy was more common (P=0.003) and mean body mass index (BMI) was higher (P=0.002) with CSII treatment. This retrospective analysis of real-world data in T1DM did not demonstrate the superiority of insulin pump treatment with regard to glycaemic control or cardiovascular risk factor control.

In sublingual, there were no adverse events in 43.3 %, with the subcutaneous, 11.3 % of the adverse events were local and 7.6 % were mild systemic. Conclusions: Sublingual was the most used, the one with the highest control of symptoms and the fewest adverse events in the study.

Tratamento das cicatrizes atróficas com insulina subcutânea / Atrophic scars treatment with subcutaneous insulin

As cicatrizes atróficas de acne, sequelas persistentes, são indesejáveis e causam impacto negativo cosmético e psicossocial nos pacientes. A questão torna-se mais delicada quando tais cicatrizes localizam-se na região pré-esternal, pelo risco do surgimento de cicatrizes hipertróficas com a realização de procedimentos na região. O papel da insulina na promoção da síntese de proteínas e gorduras é, há muito tempo, reconhecido. A utilização de suas propriedades como fator de crescimento para tratar estas sequelas parece lógica e provou ser gratificante cosmeticamente, com melhora na qualidade de vida

Atrophic acne scars are persistent and undesirable sequelae that have a negative cosmetic and psychosocial impact on patients. This issue becomes more delicate when such scars are located in the presternal region due to the risk of hypertrophic scars appearing when performing these procedures in the area. The literature has long recognized the role of insulin in promoting protein and fat synthesis. Insulin properties as a growth factor to treat these sequelae seems logical and has proved cosmetically satisfying, with quality of life improvement

RESUMO Objetivo: Identificar a conduta referida de profissionais da enfermagem, do estado de São Paulo, sobre Práticas de Medicações Injetáveis. Método: Estudo tipo survey que identificou a frequência referida sobre Práticas de Medicações Injetáveis mediante resposta de questionário eletrônico, validado, entre setembro e dezembro de 2017. Resultados: Considerando as 1.295 respostas computadas, foram identificadas inconformidades como compartilhamento de frascos multidoses para dois ou mais pacientes (10,8%), reutilização de insumos de uso único, como seringas para salinização de pacientes diferentes (1,2%) e reencape de agulhas após uso (4,9%). Foram referidas maior adesão ao uso de luvas para administração de injeções endovenosas (80,5%) e falta de treinamento para manipulação de dispositivos de segurança (13%). Dados correlacionais apontaram que, quanto maior a idade, melhor era a conduta referida na prática de injetáveis. Conclusão: Embora a maioria das condutas configure-se dentro das Boas Práticas de Medicações Injetáveis, há relatos de práticas de risco, como compartilhamento de insumos de uso único. O treinamento para uso de dispositivos de segurança ainda não é uma realidade para todos os profissionais, visto que muitos o referiram como raro.

RESUMEN Objetivo: Identificar la conducta de profesionales de enfermería del estado de São Paulo sobre Prácticas de Medicaciones Inyectables. Método: Se trata de un estudio tipo survey, el cual identificó la frecuencia de Prácticas de Medicaciones Inyectables mediante respuesta de un cuestionario electrónico, validado entre septiembre y diciembre de 2017. Resultados: Teniendo en cuenta las 1.295 respuestas computadas, se identificaron inconformidades como el uso de frascos de dosis múltiples para dos o más pacientes (10,8%), la reutilización de insumos de un solo uso, como jeringas para la salinización de diferentes pacientes (1,2%) y el reencapuchado de agujas después de su uso (4,9%).

Conclusión: Aunque la mayoría de las conductas se configuran dentro de las Buenas Prácticas de Medicaciones Inyectables, se informa sobre la existencia de prácticas de riesgo, como el compartir insumos de un solo uso. La capacitación en el uso de dispositivos de seguridad aún no es una realidad para todos los profesionales y muchos han declarado que raramente se los entrena en esa área.

ABSTRACT Objective: To identify the self-reported injectable medications of nursing professionals in the state of São Paulo. Method: Survey study that assessed the self-reported frequency of injection medications through a validated electronic questionnaire, applied from September to December 2017. Results: The 1,295 computed responses showed non-compliances such as sharing multidose vials for two or more patients (10.8%), reusing single-use supplies, such as use of saline flush syringes for different patients (1.2%) and needle recapping after use (4.9%). Greater adherence to glove use for administration of intravenous injections (80.5%) and lack of training for handling safety devices (13%) were reported. Correlational data showed that, the older the age, the better the self-reported injecting practices. Conclusion: Although most practices are within Safe Injecting practices, there are reports of risky practices, such as sharing single-use supplies. Training for the use of safety devices is not yet a reality for all professionals, since many reported it as rare.

[The safety and efficacy of low dose subcutaneous decitabine combined with arsenic trioxide in patients with inermediate or higer-risk myelodysplastic syndrome].

To retrospectively analyze the safety and efficacy of low dose subcutaneous decitabine combined with arsenic trioxide in patients with intermediate or high-risk myelodysplastic syndrome (MDS). Three of the total 11 MDS patients achieved complete remission (CR) and 6 achieved hematological improvement (HI), 1 stable disease (SD), and 1 progressive disease (PD). One patient was treated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). The median follow-up time was 413(90-1 275) d. Nine patients were still alive. Low dose subcutaneous decitabine combined with arsenic trioxide can be an alternative regimen for intermediate or high-risk MDS patients.

[One case of severe subcutaneous soft tissue infection caused by nonstandard insulin injection].

On January 1st 2018, a male 44 years old diabetic patient with subcutaneous soft tissue infection in right thigh was admitted to our hospital. The patient repeatedly used the same needle to inject insulin subcutaneously in the unsterilized right thigh, and his blood glucose was badly controlled in the long term. Severe subcutaneous soft tissue infection of the right thigh occurred after his fatigue, accompanied with ketoacidosis. Then he received conservative treatment in the local hospital for one month, but the infection persisted. After being transferred to our hospital, we highly suspected the diagnosis of necrotizing fasciitis according to previous test indicators and local B-ultrasound results, but suggestion of aggressive surgery was refused. So we treated him with conservative therapies using sensitive antibiotics and supportive remedies. The patient was basically healed after treatment of 1 month and he was recovered well during the follow-up 2 months after discharged from our hospital. This case emphasizes the importance of standard injection of insulin and early diagnosis of severe subcutaneous soft tissue infection.

Insulin Injection Technique Questionnaire: results of an international study comparing Brazil, Latin America and World data.

BACKGROUND: In 2014-2015, the largest international survey of insulin injection technique in patients with diabetes taking insulin was conducted in 42 countries, totaling 13,289 participants. In Brazil, patients from five public health centers were included. This study aims to evaluate insulin injection technique in Brazilian patients and compare results with Latin America (LatAm) and World data. METHODS: The insulin Injection Technique Questionnaire (ITQ) survey consisted of an initial patient section (questions applied by an experienced nurse), followed by observation of injection technique and examination of the injection sites by the health care professional. RESULTS: In Brazil, 255 patients were evaluated: 25% had type 1 diabetes mellitus (T1DM) and 75% had T2DM. In this study, 79% of patients injected less than 4 times a day, and 17.3% used insulin pens, compared to 28% in LatAm and 86% worldwide. Syringes were used by 78% of patients in Brazil, compared to 65% in LatAm and 10% globally. Differences in needle length were substantial-nearly 64% in Brazil inject with 8 mm length needle compared to 48% in LatAm and 27% worldwide. Additionally, 48% of patients in Brazil skip doses, 80% reuse pen needles and 57% reuse syringes with 27% having lipohypertrophy by exam. CONCLUSION: Brazilian patients use syringes more and pens less, inject with larger needles and have more lipohypertrophy when compared to Latin America and World data. Their re-use of needles and syringes is also high. This study showed that in Brazil, teaching of proper injection technique has to be more widespread, and more intensive during diabetes educational sessions, and the type of delivered supplies must be updated to smaller, shorter needles preferred by patients, in order to facilitate adherence to treatment. From the ITQ, we conclude that there are many aspects of insulin injection technique that may be improved in Brazil.

Subcutaneous Injection of Nitroglycerin at the Radial Artery Puncture Site Reduces the Risk of Early Radial Artery Occlusion After Transradial Coronary Catheterization: A Randomized, Placebo-Controlled Clinical Trial.

BACKGROUND: Transradial coronary catheterization is widely used as a diagnostic or interventional procedure for coronary disease. However, it can lead to adverse complications, such as radial artery occlusion. We sought to determine whether preprocedural injection of nitroglycerin at the radial artery puncture site reduces radial artery occlusion. METHODS AND RESULTS: A total of 188 patients undergoing transradial coronary catheterization were randomized in a single-blind fashion to receive subcutaneous injection of 0.5 mL 0.1% nitroglycerin or a placebo at the radial artery puncture site. The participants underwent ultrasound examinations of the radial artery before and at 24 hours after the procedure. Of the 188 patients enrolled, 182 completed the study, as the procedure failed in 2 participants in the nitroglycerin-treated group and 4 in the placebo group. Baseline demographic and clinical characteristics were similar between 2 groups. Comparing the radial artery diameters before and after the operation, there was a statistically significant increase in the nitroglycerin-treated group (2.48±0.45 versus 2.45±0.46 mm; P=0.003) but a decrease in the placebo control group (2.41±0.50 versus 2.46±0.49 mm; P<0.001). Importantly, the incidence of radial arterial occlusion was substantially lower in the nitroglycerin-treated group than in the placebo control group (5.4% versus 14.4%; P=0.04). There was not significant difference in other complications (forearm hematoma and radial artery pseudoaneurysm, respectively), and there was no incidence of cause hypotension or an intolerable headache. CONCLUSIONS: Subcutaneous injection of nitroglycerin at the radial artery puncture site dilates the radial artery and reduces the incidence of early radial artery occlusion post-catheterization.

[The clinical safety and efficacy of low dose subcutaneous decitabine in treating acute myeloid leukemia and intermediate- or higer-risk myelodysplastic syndromes in the elderly patients].

To retrospectively analyze the safety and efficacy of low dose subcutaneous decitabine regimen in patients with acute myeloid leukemia (AML) and intermediate- or higer-risk myelodysplastic syndrome (MDS). Of 6 AML cases, 2 achieved complete remission (CR), 2 with partial remission(PR), 1 with stable disease(SD), 1 with progressive disease(PD). As to the 8 MDS patients, one achieved CR and 6 with hematologic improvement (HI), 1 case SD. Low dose subcutaneous decitabine regimen could be an alternative choice of older AML or MDS patients.

[Use of intracutaneous or subcutaneous botulinum toxin for postherpetic neuralgia]. / Einsatz intra- bzw. subkutaner Botulinumtoxine bei Post-Zoster-Neuralgie.

BACKGROUND: Botulinum neurotoxin (BoNT), a toxin of the anaerobic spore-forming bacterium Clostridium botulinum is used as a drug for alleviating muscle spasticity. Other indications include the cosmetic application in facial muscles, hyperhidrosis and neurogenic bladder disorders. It has been approved since 2010 as the first prophylactic treatment for chronic migraine. The analgesic effect of BoNT was observed early on and is currently the subject of intensive research. Painful postherpetic neuralgia is a common complication of an infection with herpes zoster virus. Despite modern treatment algorithms and medication, satisfactory pain treatment is not achieved in all patients. The use of BoNT could represent a new treatment option. AIM: The aim of this article is to provide an overview of the current evidence for the use of BoNT for postherpetic neuralgia. MATERIAL AND METHODS: We conducted a systematic literature search with the keywords "botulinum" and "neuropathic" and included original articles in which BoNT was used subcutaneously or intradermally for the treatment of postherpetic neuralgia. RESULTS: The initial search yielded 212 results. After a title and abstract screening, the number was reduced to 11 relevant publications (5 case reports or series and 6 prospective studies). DISCUSSION: The results in the currently available literature show that BoNT is an effective therapeutic option for postherpetic neuralgia. In all studies, a significant effect on the pain and also on relevant patient-oriented secondary variables, such as the quality of life and especially the quality of sleep was shown. The only reported side effect was pain during administration.

The Relationship of a Combination of Human Adipose Tissue-Derived Stem Cells and Frozen Fat with the Survival Rate of Transplanted Fat.

BACKGROUND: The survival rate of grafted fat is difficult to predict, and repeated procedures are frequently required. In this study, the effects of the freezing period of harvested adipose tissue and the addition of human adipose tissue-derived stem cells (ASCs) on the process of fat absorption were studied. METHODS: Adipose tissue was obtained from patients who underwent a lipoaspirated fat graft. The fat tissue was cryopreserved at -20℃ in a domestic refrigerator. A total of 40 nude mice were used. The mice in the experimental group received three different subcutaneous injections in the back: an injection of fresh fat and ASCs, an injection of fat that had been frozen for one month and ASCs, and an injection of fat that had been frozen for two months and ASCs. The control mice received fat grafts without ASCs. The mice were sacrificed at four or eight weeks after the procedure, and the grafted fat tissues were harvested. The extracted fat was evaluated using photographic analysis, volume measurements, and histological examination. RESULTS: In the control group, the fat resorption rates four weeks after transplantation in the grafts of fresh fat, fat that had been frozen for one month, and fat that had been frozen for two months were 21.14%, 22.46%, and 42.56%, respectively. In the experimental group, the corresponding resorption rates were 6.68%, 13.0%, and 33.9%, respectively. CONCLUSIONS: ASCs can increase the fat graft survival rate. The use of ASCs in fat grafting can reduce the need for repeated fat grafts and provide good long term results.

Eficacia de la inmunoterapia subcutánea con extractos de ácaros en adultos asmáticos / Effectiveness of subcutaneous immunotherapy with mite extracts in asthmatic adults

Fundamento: la inmunoterapia alergeno específica constituye el único tratamiento capaz de modificar el curso natural de las enfermedades alérgicas, tiene efecto multiorgánico y duradero a largo plazo después de suspender su administración y se han probado sus efectos preventivos, tanto en la prevención de nuevas sensibilizaciones como en la progresión de la rinitis al asma. Objetivo: evaluar la eficacia de una nueva pauta de inmunoterapia subcutánea con extractos alergénicos de ácaros en adultos asmáticos. Método: se realizó un ensayo clínico fase II, abierto, aleatorizado en 50 pacientes con diagnóstico de asma bronquial leve o moderada, sensibles a ácaros del polvo por prueba de Prick .La población objeto de estudio estuvo constituida por 200 pacientes con antecedentes patológicos de asma bronquial y edades entre 18 y 50 años, que acudieron a la consulta de Alergología del Hospital Universitario Manuel Ascunce Domenech, desde mayo de 2011 a mayo de 2012. A los mismos se les administró inmunoterapia subcutánea con extractos de ácaros (Dermatophagoides pteronyssinus, y Blomia tropicalis) a concentraciones de 20 UB/ml, 200 UB/ ml, 2 000 UB/ml y 20 000 UB/ml en el primer grupo, según el esquema propuesto por el BIOCEN, se alcanzó la dosis de mantenimiento en 13 semanas a intervalos semanales. El segundo grupo recibió pauta convencional de 16 semanas. Resultados: en la evaluación de la eficacia se comprobó una reducción de los síntomas clínicos y del consumo de medicación al final del tratamiento en ambos grupos pero de manera significativa en el grupo estudio (p=0,020). La reactividad cutánea a los ácaros disminuyó significativamente en el grupo estudio con respecto al grupo control. Conclusiones: se demuestró un alto grado de eficacia de esta pauta más acortada con extractos de ácaros, lo que garantiza una adhesión al tratamiento superior a la pauta de 16 semanas con frecuencia bisemanal.

Background: allergen-specific immunotherapy is the only treatment capable of modifying the natural course of allergic diseases; it has multiple organ and long term effect after stopping its administration and its preventive effects have been tested, both in the prevention of new sensitizations and in the progression of rhinitis to asthma. Objective: to evaluate the effectiveness of a new subcutaneous immunotherapy schedule with mite extracts in asthmatic adults. Method: a phase II, open, randomized clinical trial was conducted in 50 patients with diagnosis of mild or moderate bronchial asthma, sensitive to dust mites by Prick test. The study population was constituted by 200 patients with a pathological history of bronchial asthma and aged between 18 and 50 years, who were treated in the Allergology consultation at the University Hospital Manuel Ascunce Domenech, from May 2011 to may 2012. They were given subcutaneous immunotherapy with mite extracts (Dermatophagoides pteronyssinus and Blomia tropicalis) at concentrations of 20 ml/UB 200 UB / UB/ml 2 000 and 20 000 ml/UB/ml in the first group, according to the schedule proposed by BIOCEN, it was reached the maintenance dose in 13 weeks at weekly intervals. The second group received conventional schedule of 16 weeks. Results: it was found a reduction of clinical symptoms as well as in medication consumption at the end of the treatment in both groups, but significantly in the study group (p=0,020). Skin reactivity to mites significantly decreased in the study group regarding the control group. Conclusions: a high degree of effectiveness of this new schedule with mites’ extracts was demonstrated, this guarantees a greater adhesion to treatment, which it is far superior to the previous 16-week schedule with a twice-weekly frequency.

Análise da lipoenxertia estruturada na redefinição do contorno facial / Analysis of structured fat grafting for redefining facial contours

INTRODUÇÃO: A enxertia de gordura como preenchimento no rejuvenescimento e melhoria do contorno facial vem sendo usada por alguns autores e demonstra um potencial excelente como método de escolha para essa finalidade, uma vez que tem como premissa o princípio básico de corrigir as deformidades com o tecido mais semelhante possível. O objetivo deste trabalho foi avaliar clinicamente a eficiência da enxertia de gordura estruturada na redefinição do contorno facial. MÉTODO: Foi realizada análise retrospectiva de 39 pacientes submetidos a lipoenxertia estruturada para a redefinição do contorno facial, entre 2002 e 2012. A seleção de pacientes incluiu correção de deformidades, assimetrias, harmonização do contorno e aumento da projeção óssea, mas excluiu o rejuvenescimento per se. A avaliação do resultado clínico foi realizada pelo paciente e pelo cirurgião, com auxílio de documentação fotográfica pré e pós-operatória. O resultado clínico foi classificado pelo paciente e cirurgião, empregando escala que variava de 1 a 3: (1) o objetivo não foi alcançado de forma alguma; (2) o objetivo foi alcançado parcialmente; ou (3) o objetivo foi alcançado totalmente. Foi realizado, também, levantamento de prontuários para obtenção dos seguintes dados: idade, alteração ponderal, volume enxertado por área, número de sessões de enxertia realizadas, história de tabagismo e complicações. RESULTADOS: As médias das avaliações do cirurgião e paciente foram, respectivamente, 2,6 ± 0,6 e 2,7 ± 0,5, havendo correlação estatisticamente significante (P < 0,0001). Não foi encontrada relação significativa entre as avaliações e idade, alteração ponderal, volume de enxertia ou tabagismo, com uma única exceção. CONCLUSÕES: A lipoenxertia estruturada demonstrou ser eficiente adjuvante na redefinição do contorno facial e sua eficiência não foi prejudicada por idade, alteração ponderal ou tabagismo. O volume a ser enxertado deve ser adequado às necessidades específicas de cada área.

INTRODUCTION: Fat grafting as a filling method for the rejuvenation and enhancement of facial contours was demonstrated by some authors to be an excellent alternative method for redefining facial contours, based on the premise that the donor tissue used in the correction of the deformities has similar characteristics as the recipient tissue. The objective of the present study was to clinically evaluate the efficiency of structured fat grafting when redefining facial contours. METHODS: A retrospective evaluation was performed in 39 patients who underwent structured fat grafting to redefine their facial contours between 2002 and 2012. The patients selected included those who underwent corrections of deformities, asymmetrical features, contour smoothing, and increased bone projection. Patients who underwent facial contour rejuvenation were excluded. The clinical outcome assessment was performed by the patient and surgeon, with the aid of preoperative and postoperative photographic documentation. The clinical outcome was rated by the patient and surgeon, using a scale ranging from 1 to 3, defined as follows: 1, the objective has not been achieved in any way; 2, the objective was partially achieved; or 3, the objective was fully achieved. In addition, a survey was conducted using the patients' medical charts to obtain the following data: age, weight change, volume grafted by area, number of grafting sessions performed, history of smoking, and complications. RESULTS: The mean surgeon and patient assessment scores were 2.6 ± 0.6 and 2.7 ± 0.5, respectively, with a statistically significant correlation (P < 0.0001). No significant relationship was found between the assessments and age, weight change, graft volume, or smoking habit, with the exception of the cheekbone area. CONCLUSIONS: Structured fat grafting proved to be an efficient adjuvant technique for redefining facial contours, and its efficiency was not affected by age, weight change, or smoking habit. However, the fat volume to be grafted should be adequate for the specific needs of each area.

Administração de antibióticos por via subcutânea: uma revisão integrativa da literatura / Administration of antibiotics subcutaneously: an integrative literature review

OBJETIVO: Caracterizar os artigos científicos relacionados ao uso de antibióticos por via subcutânea em pacientes com difícil acesso venoso em cuidados paliativos quanto à tolerância local e eficácia terapêutica. MÉTODOS: Revisão integrativa da literatura realizada nas bases de dados LILACS, CINAHL, PUBMED, EMBASE e Biblioteca Cochrane, utilizando-se como referencial teórico a Prática Baseada em Evidências. RESULTADOS: 17 artigos foram selecionados com dez antibióticos diferentes, sendo o Ceftriaxona, o antibiótico mais estudado. Constatou-se a eficácia terapêutica com base nos parâmetros farmacocinéticos e clínicos. A tolerância local esteve associada à maior diluição dos antibióticos. Com administração de aminoglicosídeos, observaram-se lesões graves e necrose tecidual. A baixa tolerância reforça a restrição de uso apenas para essa classe de antibióticos. CONCLUSÃO: As previsões de eficácia terapêutica e a boa tolerância sugerem uma possibilidade a ser considerada quando se deseja uma via de administração parenteral alternativa, porém recomenda-se cautela, visto que nenhum dos estudos avaliou pacientes em cuidados paliativos.

OBJECTIVE: To characterize scientific articles related to the use of antibiotics by the subcutaneous route in patients with difficult venous access in palliative care, regarding local tolerance and therapeutic efficacy. METHODS: Integrative literature review conducted in the databases of LILACS, CINAHL, PubMED, EMBASE and the Cochrane Library, using Evidence-Based Practice as a theoretical framework. RESULTS: Seventeen articles were selected with ten different antibiotics, with ceftriaxone being the most studied antibiotic. Therapeutic efficacy was observed based on pharmacokinetic and clinical parameters. The local tolerance was associated with greater dilution of antibiotics. With administration of aminoglycosides, serious injuries and tissue necrosis were observed. A low tolerance reinforced the restriction of use only to this class of antibiotics. CONCLUSION: The predictions of therapeutic efficacy and good tolerance suggest a possibility to be considered when there is need of an alternative parenteral route of administration, but caution is advised, since none of the studies evaluated patients in palliative care.

Randomized clinical trial to assess pain and bruising in medicines administered by means of subcutaneous and intramuscular needle injection: Is it necessary to have needles changed? / Ensaio clínico randomizado para avaliação de dor e hematoma em administração de medicamentos por via subcutânea e intramuscular: há necessidade de troca de agulhas? / Ensayo clínico aleatorio para evaluación del dolor y hematoma durante la administración de medicamentos por vía subcutánea e intramuscular: ¿Es necesario cambiar las agujas?

This clinical trial aimed at comparing the intensity of pain and bruising by subcutaneous and intramuscular injections using and retractable fixed syringes and needles and syringes with no needles combined, at a public hospital in Sao Paulo, for six months. We evaluated the perception of pain in case of intramuscular (n=1000) and subcutaneous injections (n=240). In subcutaneous application, bruise formation was also verified. Pain and bruising scores were higher in the group with no needles combined (p<0.001) and (p<0.029), respectively. The test power in relation to the pain scale of was 0.98. The use of retractable fixed needles is recommended in the application of subcutaneous and intramuscular injections. Clinical trial registration number: NCT01271608.

Este ensaio clínico teve como objetivo comparar a intensidade da dor e hematoma consequentes a injeções por via subcutânea e intramuscular, utilizando seringas e agulhas fixas retráteis e seringas com agulhas não conjugadas, em hospital público na cidade de São Paulo, durante seis meses. Foi avaliada a percepção da dor na injeção intramuscular (n=1.000) e na subcutânea (n=240). Na aplicação por via subcutânea, verificou-se também a formação de hematoma. A pontuação de dor e hematoma foi maior no grupo com agulhas não conjugadas (p<0,001 e p<0,029, respectivamente). O poder do teste em relação à escala de dor foi de 0,98. Recomenda-se o uso de agulha fixa retrátil na aplicação de injeções intramusculares e subcutâneas. Registro de ensaio clínico nº NCT01271608.

Comparison of follitropin ß administered by a pen device with follitropin ß administered by a conventional syringe in patients undergoing IVF-ET.

OBJECTIVE: To compare the effectiveness and convenience of a pen device for the self-administration of follitropin ß with a conventional syringe delivering follitropin ß solution in patients undergoing IVF-ET. METHODS: GnRH agonist long protocol was used for controlled ovarian stimulation (COS) in all subjects. A total of 100 patients were randomized into the pen device group or the conventional syringe group on the first day of COS. Local tolerance reactions were assessed within 5 minutes, at 1 hour and at 3 hours after each injection. On the day of hCG injection, patients were asked to rate their overall pain and convenience experienced with self-injection on a visual anlaogue scale (VAS). RESULTS: There were no differences in patients' characteristics between the two groups. The duration of COS was significantly shorter in the pen device group than in the conventional syringe group. Patients included in the pen device group needed a significantly smaller amount of follitropin ß. However, no differences between the two groups were found in IVF results and pregnancy outcome. The incidence of local pain within 5 minutes, at 1 hour and at 3 hours after the injection was significantly lower in the pen device group. VAS scores indicated that injections using the pen device were significantly less painful and more convenient. CONCLUSION: The pen device for self-administration of follitropin ß is less painful, safer and more convenient for the patients, and can be more effective because of the shorter duration and smaller dose of follitropin ß when compared with the conventional syringe.

Lipoenxertia: técnica expansiva / Fat grafting by expansive technique

Introdução: A lipoenxertia pela técnica expansiva é descrita e analisada nos seus detalhes para preenchimentos nas diversas regiões da face. Método: Mediante modificação da soluçãode Klein, as áreas receptoras distribuídas regionalmente recebem volumes específicos de solução anestésica dissolvida no ringer lactato até ficarem estumescidas. A face posterior do braço, região de eleição doadora da gordura, é também expandida com a mesma solução.Cuidados com a gordura retirada são descritos nas suas minúcias, assim como os tipos de seringas, agulhas e cânulas utilizadas em cada região da face. A técnica baseia-se no princípio de maior superfície de contato entre o leito receptor e as células adiposas suspensas em meio líquido, sem o uso da hipercorreção. Resultados: Casos ilustrativos comprovam os efeitosdesta técnica através da qualidade dos resultados a longo prazo.

Introduction: The lipo cells graft through the expansive method is described and analyzed in their details to fill different regions of the face, among other regions of the body, to restore its contour. Methods: Based on Klein’ solution, a lactate ringer and anesthetic became turgid. Each face region receives specific volume of this solution. The posterior region of the arm, selected as donor site, is also injected in the same routine. Cares with the fat removal aredescribed in its details, including the types of syringe, needles and cannula, used in each region of the face. The technique is based on the great surface contact of the fat cells suspension in the solution to be injected in the receiving areas, without any compressive action nor hyper correction. Results: Ilustrative cases confirm the result’s quality in long term follow up.
