RESUMO

BACKGROUND: Intense focused ultrasound (IFUS) has demonstrated moderate efficacy for facial laxity of the aging face. Pressure- and dose-controlled transcutaneous pneumatic injections of hypertonic glucose solution (TPIG) are a minimally invasive way to deliver solution into the skin for therapeutic purposes. Recently, its application around temporal areas is known to exert early-onset lifting effects with facial contour rejuvenation. AIMS: We sought to evaluate the safety and efficacy of this novel combination regimen with IFUS and TPIG for lifting and tightening of aging face. PATIENTS AND METHODS: Twenty-two Korean subjects with mild-to-moderate facial skin laxity were evaluated after receiving a sequential single session of IFUS and TPIG treatments. Dermatologists' objective assessments for general appearance, and mid- and low faces based on photographic images were performed at 1- and 12-week post-treatment follow-ups. Patients' subjective assessments were also conducted. Skin biopsies were taken at baseline and the last visit. RESULTS: Among 22 subjects, twenty (91%) demonstrated improvement after 12-week follow-up. We also observed similarly improved state just after 1 week of treatments (82%: 18/22). Specifically, improvement of the mid-face was evident from the first week, while the progress of the low face improvement was observed at the twelve week. Subjective assessments paralleled these findings. No seriously adverse effect was observed during procedures. Histologic evaluation showed greater dermal collagen fibers throughout the dermis after treatments. CONCLUSION: Combination treatment with IFUS and TPIG has beneficial effects for skin lifting and tightening with early-onset time.

RESUMO

CASE: A 57-year-old woman was found at home by paramedics to be hypoglycemic with altered mental status. She had multiple attempts at IV access and eventually a 22G IV was established and D50 was infused into her right forearm. Extravasation of the dextrose was noted after approximately 12 g of the medication was infused. She was given a dose of glucagon intramuscularly and her mental status improved. Shortly after her arrival to the emergency department, she was noted to have findings of compartment syndrome of her forearm at the site of the dextrose extravasation. She was evaluated by plastic surgery and taken to the operating room for emergent fasciotomy. She recovered well from the operation. DISCUSSION: D50 is well known to cause phlebitis and local skin necrosis as a complication. This case illustrates the danger of compartment syndrome after D50 extravasation. It is the first documented case of prehospital dextrose extravasation leading to compartment syndrome. There may be safer alternatives to D50 administration and providers must be acutely aware to monitor for D50 infusion complications.

RESUMO

OBJECTIVE: A fatal cardiac complication can occasionally present in malnourished patients during refeeding; this is known as refeeding syndrome. However, to our knowledge, hyperglycemia preceding torsades de pointes with QT prolongation during refeeding has not been reported. In the present study, we present a case in which hyperglycemia preceded torsades de pointes with QT prolongation during refeeding. The aim of this study was to determine the possible mechanism underlying QT prolongation during refeeding and indicate how to prevent it. METHODS: A 32-y-old severely malnourished woman (body mass index 14.57 kg/m2) was admitted to the intensive care unit of our institution after resuscitation from cardiopulmonary arrest due to ventricular fibrillation. She was diagnosed with anorexia nervosa. Although no obvious electrolyte abnormalities were observed, her blood glucose level was 11 mg/dL. A 12-lead electrocardiogram at admission showed sinus rhythm with normal QT interval (QTc 0.448). RESULTS: Forty mL of 50% glucose (containing 20 g of glucose) was intravenously injected, followed by a drip infusion of glucose to maintain blood glucose level within normal range. After 9 h, the patient's blood glucose level increased to 569 mg/dL. However, after 38 h, an episode of marked QT prolongation (QTc 0.931) followed by torsades de pointes developed. CONCLUSIONS: Hyperglycemia during refeeding can present with QT prolongation; consequently, monitoring blood glucose levels may be useful in avoiding hyperglycemia, which can result in QT prolongation. Furthermore, additional monitoring of QT intervals using a 12-lead electrocardiogram should allow the early detection of QT prolongation when glucose solution is administered to a malnourished patient with (severe) hypoglycemia.

RESUMO

PURPOSE OF REVIEW: To clarify misconceptions about the feasibility and risks of peritoneal dialysis that unnecessarily limit peritoneal dialysis uptake or continuation in patients for whom peritoneal dialysis is the preferred dialysis modality. The inappropriate choice of haemodialysis as a result of these misconceptions contributes to low peritoneal dialysis penetrance, increases transfer from peritoneal dialysis to haemodialysis, increases expenditure on haemodialysis and compromises quality of life for these patients. RECENT FINDINGS: Peritoneal dialysis is an excellent renal replacement modality that is simple, cost-effective and provides comparable clinical outcomes to conventional in-centre haemodialysis. Unfortunately, many patients are deemed unsuitable to start or continue peritoneal dialysis because of false or inaccurate beliefs about peritoneal dialysis. Here, we examine some of these 'myths' and critically review the evidence for and against each of them. We review the feasibility and risk of peritoneal dialysis in patients with prior surgery, ostomies, obesity and mesh hernia repairs. We examine the fear of mediastinitis with peritoneal dialysis after coronary artery bypass graft surgery and the belief that the use of hypertonic glucose dialysate causes peritoneal membrane failure. SUMMARY: By clarifying common myths about peritoneal dialysis, we hope to reduce overly cautious practices surrounding this therapy.

RESUMO

BACKGROUND: Intravenous indigo carmine has routinely been used to confirm ureteral patency after urogynecologic surgery. Recent discontinuation of the dye has altered clinical practice. In the absence of indigo carmine, we have used 10% dextrose in sterile water (D10) as cystoscopic fluid to evaluate ureteral patency. Glucosuria has been associated with urinary tract infection (UTI) in vivo and significantly enhanced bacterial growth in vitro. The concern is that the use of D10 would mimic a state of glucosuria albeit transient and increase the risk of postoperative UTI. OBJECTIVES: The objectives of this study were to compare the rates of postoperative UTI and lower urinary tract (LUT) injuries between patients who underwent instillation of D10 vs normal saline at the time of intraoperative cystoscopy after urogynecological surgery. STUDY DESIGN: This was a retrospective cohort study of all women who underwent cystoscopic evaluation of ureteral patency at the time of urogynecological surgery from May through December 2014 at a tertiary care referral center. We compared patients who received D10 cystoscopy fluid vs those who used normal saline. Outcomes included UTI and diagnosis of ureteral or LUT injuries. UTI was diagnosed according to Centers for Disease Control and Prevention guidelines by symptoms alone, urine dipstick, urinalysis, or urine culture. Descriptive statistics compared the rates of UTI between the 2 groups, and a multivariable model was fit to the data to control for potential confounders and significant baseline differences between the groups. RESULTS: A total of 303 women were included. D10 was used in 113 cases and normal saline (NS) was used in 190. The rate of UTI was higher in the D10 group than the NS group: 47.8% (95% confidence interval [CI], 38.3-57.4) vs 25.9% (95% CI, 19.8-32.8, P < .001). After adjusting for age, pelvic organ prolapse stage, use of perioperative estrogen, days of postoperative catheterization, menopausal status, diabetes mellitus, and history of recurrent UTI, the UTI rate remained significantly higher with the use of D10 (adjusted odds ratio, 3.4 [95% CI, 1.6-7.5], P = .002) compared with NS. Overall, 3 cases of transient ureteral kinking (1.0%) and one cystotomy (0.3%) were identified intraoperatively. However, ureteral and LUT injuries were not different between groups. No unidentified injuries presented postoperatively. CONCLUSION: Although the use of D10 cystoscopy fluid has been successful in identifying ureteral patency in the absence of indigo carmine, it is associated with an increased rate of postoperative UTI compared with NS.

RESUMO

BACKGROUND: The prevalence of chronic venous disease is high and occurs more frequently in females. According to the clinical, etiological, anatomical, and pathological classification (CEAP) definition, the reticular veins are included in the C1 class and are mainly associated with aesthetic complaints. Several invasive techniques are used for treatment, including mini phlebectomy, laser ablation, and radiofrequency ablation. However, a wide range of sclerosing agents may serve as minimally invasive alternatives, promoting chemical sclerosis of the vein wall. Although this technique is routinely performed around the world, there is no consensus on the most efficacious and safe chemical agent to be used. METHODS/DESIGN: Inclusion criteria are women between 18 and 69 years old with at least 10 cm long reticular veins in the lower limbs, on the outer side of the leg/thigh. Patients with CEAP 2 to 6, or with allergies, pregnancy, performing breastfeeding, or with any dermatologic or clinical problems will be excluded. Patients with venous ultrasound mapping showing involvement of saphenous trunks and/or a deep venous system will also be excluded. Patients will be randomized into two groups, one receiving 75% pure glucose and the other group receiving 0.2% polidocanol diluted in 70% glucose. Just one limb and one session per patient will be performed. The sclerosing agent volume will not exceed 5 mL. Clinical follow-up will include visits on days 7 and 60, always with photographic documentation. DISCUSSION: This project aims to enroll 96 patients and subject them to a double-blind treatment after the randomization process. The design is intended to evaluate efficacy through a primary end point and safety through a secondary end point. Forty-eight patients have currently been enrolled. Preliminary results for these patients showed that 25 received treatment, 2 were excluded, and 22 returned after 7 days and showed no greater adverse events. To date, establishing efficacy criteria has not been possible, and no patients have reached the 60-day return point. These data may help doctors choose the best chemical agent for the treatment of reticular veins. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02054325, 3/02/2014.

RESUMO

Treatment for significant hypoglycemia includes administration of dextrose containing agents, including 50% dextrose (D50%W) intravenously. Significant extravasation of D50%W can lead to complications, including skin and soft tissue injury, loss of limb, or death. The aim of this case report, using an interdisciplinary team approach, explores extravasation protocols as well as literature review, is to provide information about the proper use of hyaluronidase in patients with D50%W extravasations. A 46-year-old African American man presented to the emergency department (ED) after blood glucose level was initially 13 mg/dL. Emergency medical service established a large bore intravenous (IV) line in the right antecubital vein and administered a total of 50 g of D50%W. Upon arrival to the ED, the patient's level of consciousness had significantly improved. After arrival to the ED, the patient started complaining of pain in his right arm, near the site of the IV line insertion. On inspection, the IV site was grossly infiltrated. Hospital protocols for hyperosmolar infiltration were used. Extravasation is a common medical complication of infused medications and needs to be properly identified and treated. The multitude of skills from nursing, medicine, and pharmacy ensures that extravasation is managed appropriately and effectively to ensure safety to patients. Recognition, communication, and awareness of the institutional guidelines on how to treat infiltration and extravasation should be encouraged in all ED and intensive care unit medical personnel who deal with a variety of infusions and IV medications that have serious implications if not treated correctly.

RESUMO

A meta-analysis and systematic review assessing randomised controlled trials (RCTs) was sought to determine whether subcutaneous injection of insulin with hypertonic glucose promotes healing in postoperative incisions with aseptic fat liquefaction. We searched the Cochrane library, Pubmed, EMBASE, National Science Digital Library (NSDL) and China Biological Medicine Database (CBMdisc) for literature published from 1 January 1990 to 30 September 2011. RCTs that evaluated subcutaneous injection of insulin with hypertonic glucose as a treatment for postoperative wound with fat liquefaction were sought. Wound healing was the primary endpoint. Jadad score and Cochrane Collaboration's tool were used for assessing quality of studies and risk of bias. We abstracted data regarding time to wound healing, cost and adverse effects. The random-effects inverse variance model was used for all analyses using weighted mean difference and 95% confidence interval. Eight trials (414 participants) were identified that met the inclusion criteria. Subcutaneous injection of insulin with hypertonic glucose significantly reduces time to healing by 6·33 days compared with conventional drainage, with less cost. There was no report concerning adverse effects. Subcutaneous injection of insulin with hypertonic glucose may improve the healing process in postoperative wounds with aseptic fat liquefaction.

RESUMO

Extravasation is the diffusion of a product injected intravenously into the perivascular or subcutaneous spaces. Skin necrosis of iatrogenic origin can be observed for example with a subcutaneous perfusion of solution containing potassium chloride or the extravasation of 30% hypertonic glucose serum. Whenever a product is injected, the administration route for which the product has obtained marketing authorisation must be respected and a perfusion time of at least 4 to 5 hours per litre of solution perfused must be observed.

RESUMO

BACKGROUND: Oxidative stress has been implicated in the development of peritoneal damage. The aim of this study was to evaluate the effects of N-acetylcysteine (NAC) in a rat peritoneal infusion model. METHODS: Eighteen male Wistar rats were divided in 3 groups: (i) control group; (ii) HDS group, receiving peritoneal dialysis solution (PDS); and (iii) HDS+NAC group, receiving PDS and oral NAC. Six weeks later they were evaluated for dialysate to plasma urea ratio (D/P), ratio of glucose concentration in peritoneal fluid (G1/G0), thiobarbituric acid reactive substances in plasma and urine and histology of peritoneal membrane. RESULTS: The HDS+NAC group presented a lower increase in solute transport (D/P 0.51 ± 0.1, and G1/GO 0.35 ± 0.06) in comparison with the HDS group (D/P 0.67 ± 0.1; p=0.03, and G1/G0 0.27 ± 0.07; p=0.01). The HDS+NAC group showed lower thiobarbituric acid reactive substance concentrations compared with the HDS group. In the treated group, the peritoneal membrane presented lower thickness. CONCLUSIONS: Functional and histological peritoneal changes were significantly reduced by the treatment with NAC.

RESUMO

The aim of this study was to evaluate longitudinal changes in dialysate cancer antigen 125 (dCA125) levels over time and to analyze relationships between dCA125 and peritoneal glucose exposure (PGE) in children undergoing long-term peritoneal dialysis (PD). The study group included seven boys and four girls (mean age 13 ± 5.1 years) with a mean PD duration of 84.0 ± 1.1 months. A peritoneal equilibration test (PET) was performed, and dCA125 levels were measured in all patients. Peritoneal appearance rates (AR) of dCA125, the velocity of the decrease in dCA125AR values, and annual PGE levels were also calculated. The final tests were performed at a mean of 63.3 ± 3.5 months after the initial ones. Both dCA125 and dCA125AR levels showed statistically significant decrements during the follow-up period (p = 0.003), with the velocity of decrease in dCA125AR found to be 52.6 ± 19.4%. There were no significant differences in peritoneal transport parameters between the beginning and end of the study period. PGE values were significantly higher in the last year of the study than in the first year (p = 0.014), but the velocity of the decrease in dCA125AR levels was not related to total PGE. In conclusion, a significant decline was found in dCA125 and CA125 AR levels, reflecting mesothelial cell mass, in children undergoing long-term PD (>5 years), but these were not related to PGE.

RESUMO

Chylothorax is characterized by the presence of chyle in the pleural space and cardiothoracic surgery accounts for nearly half of all the cases. Treatment of chylothorax has traditionally been nonoperative, with alternative medical therapies involving the administration of octreotide or pleurodesis. Pleurodesis with chemical agents has previously been reported, but never with 50% glucose and 0.1% xylocaine. Herein, we report a successful method of intrapleural instillation of 50% glucose and 0.1% xylocaine to treat chylothorax. Five patients treated with this method were all recovered rapidly. This method can generate extensive adherence and prevent the effusion of the chylous fluid with minor side effects.

RESUMO

BACKGROUND: Tissue hyperreactivity of target organs to nonspecific stimuli is known to be an important factor in influencing the clinical picture of allergic disease. OBJECTIVE: To identify the sensitivity and specificity of a hyperosmolar conjunctival provocation test in predicting conjunctival hyperreactivity and to relate this reactivity to the presence of ocular discomfort in subjects with and without allergy. METHODS: In 50 healthy patients and 19 patients with allergic conjunctivitis during remission phase, symptoms of ocular discomfort triggered by nonspecific stimuli were identified and graded with a discomfort score. Subjects were then challenged with a glucose solution at increasing concentrations (from 10% to 50%). The glucose concentration that elicited 2+ conjunctival hyperemia was considered the provoking dose. The response to this hyperosmolar provocation in subjects with ocular discomfort was compared with that of asymptomatic subjects. Sensitivity and specificity of the test in predicting conjunctival hyperreactivity were analyzed. RESULTS: Six of 50 healthy subjects and 12 of 19 subjects with allergy complained of ocular discomfort after exposure to nonspecific stimuli. The hyperosmolar provocation test discriminated between subjects with and without ocular discomfort (mean provoking dose: 39.5% +/- 5% and 47.5% +/- 5% glucose, respectively; P < .001). Forty percent glucose was the optimal threshold dose that demonstrated the highest sensitivity and specificity for prediction of conjunctival hyperreactivity. Discomfort scores were significantly related to provoking dose values (P < .05). CONCLUSION: This study provides a standardized procedure to detect nonspecific conjunctival hyperreactivity independent of underlying atopy. CLINICAL IMPLICATIONS: Hyperosmolar provocation test may be useful for identifying conjunctival hyperreactivity in subjects with and without allergy with a history of ocular discomfort.

RESUMO

OBJETIVO: Investigar as alterações macroscópicas e microscópicas do mesentério e do peritônio parietal quando se administra a solução aquosa de glicose hipertônica a 10% e a 25% na cavidade peritoneal de rato.MÉTODOS: 90 ratos fêmeas (n=90), adultos, "Wistar", jovens, com peso variando de 180 a 250 gramas foram divididos em 3 sub-grupos (A, B e C) contendo cada um 30 animais com procedimentos idênticos, diferindo apenas no período de observação. Os números de 1 a 30 constituem o grupo A ou grupo-controle (NaCl 0,9%), os números de 31 a 60 constituem o grupo B ou grupo-glicose a 10% e os números de 61 a 90 constituem o grupo C ou grupo- glicose a 25%. Realizando-se posteriormente laparotomia com incisão mediana longitudinal de pele a 2 cm abaixo do processo Xiphoideus sterni, estendendo-se por 3 cm caudalmente na linha média ventral. A escolha do procedimento a ser realizado para introdução na cavidade peritoneal de 2 ml de uma solução de cloreto de sódio 0,9% (controle), de glicose hipertônica a 10% e de glicose hipertônica a 25%. Em períodos correspondentes às 6h, 24h e 48h de pós-operatório, os animais de cada grupo foram reoperados, sendo realizada avaliação macroscópica e microscópica além dos registros das alterações histológicas do mesentério e peritônio parietal.RESULTADOS: Na microscopia do mesentério observou-se que 30 animais (33,4%) apresentaram linfonodos hiperplásicos; 6 animais (6,6%) com fibrose reacional; 10 animais (11,1%) com intensa congestão vascular; 16 animais (17,8%) com inflamação crônica inespecífica; 28 casos (31,1%) sem alteração. A microscopia do peritônio revelou 6 casos com fibrose reacional (3,3%) 174 casos (96,7%) sem alteração histológica. CONCLUSÃO: As soluções de glicose a 10% e a 25% não causam necrose tecidual quando introduzidas na cavidade peritoneal. O processo reacional inflamatório é de igual intensidade tecidual comparando-se ao uso da solução de NaCl a 0,9%.

RESUMO

PURPOSE: The objective of the experimental study is to detect the macroscopic and microscopic alterations of the mesenterium and parietal peritoneum when hypertonic glucose aqueous solution 10%-25% is administrated into the peritoneal cavity of the rat. METHODS: 90 Wistar females young rats adults were used weighing between 180-250 g, numbered 1 to 90, establishing unique group and divided in three groups (A, B, C) of 30 animals chosen aleatory manner. 0.9% saline solution was used called control group, or group A, 10% glucose solution named group B, and in the others 30 was used 25% glucose solution named group C, differing in the observation period, (06 h, 24 h and 48 h), but with the same procedure. A midline abdominal wall laparotomy was made and in the animals of the control group was injected 2 ml of a 0.9% saline solution into the peritoneal cavity. After, we made a suture in mass without to include the peritoneum. For the others groups (B, C) the rats received 10% glucose solution and 25% glucose solution injected into the peritoneal cavity respectively. All groups were kept under observation and the results were submitted to statistical analysis by a longitudinal and transversal comparative study. RESULTS: A new surgery was done in 6 h, 24 h and 48 h, and we observed in macroscopic evaluation, the presence of fluid, serous uniform and rosy all over the cavity. Vascular congestion was present. We dried out 90 fragments of mesenterium and 90 fragments of parietal peritoneum bilateral. In the microscopic study, necrosis was not present. For the mesenterium histological study we observed 16 cases (17.8%) unspecific chronic inflammation, 30 cases (33.4%) hyperplasc linfonod, 10 cases (11.1%) high vascular congestion, 6 cases (6.6%) reaction fibrosis and 28 cases (31.1%) no alteration. For the parietal peritoneum histological study we observed 6 cases (3.3%) reaction fibrosis and 174 cases (96.7%) no alteration. Giant cell was not present. In the statistical analysis statistic there is no significance between the groups (p>0.05). CONCLUSION: Hypertonic glucose solution and NaCl 0.9% on the mesenterium and parietal peritoneum do not produce tissue necrosis in a rat and the inflammation process has the same intensity.
