RESUMO

CLINICAL QUESTION: In adults with chronic pain, do yoga and other meditative movement therapies to improvement in chronic pain symptoms? ANSWER: Yes. However, in each of the studies reviewed, yoga classes were included as part of the pain management regime, sometimes alone and sometimes in tandem with DVDs or audiotapes. We feel that no exercise therapy program should be undertaken without professional coaching from certified, registered and qualified instructors. DATE ANSWER WAS DETERMINED: August 2014, June, 2015, August 2015. LEVEL OF EVIDENCE FOR THE ANSWER: A. SEARCH TERMS: chronic pain, yoga, exercise therapy, meditative movement therapy. INCLUSION CRITERIA: Adults; meta-analyses; systematic reviews; cohort studies; randomized controlled trials; practice guidelines; articles from 2010 to present. EXCLUSION CRITERIA: Children younger than 18 years of age, Pilates.

RESUMO

CLINICAL QUESTION: In menopausal women who experience regular hot flashes, does treatment with selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitors (SNRIs) reduce the frequency and/or severity of hot flashes? ANSWER: Yes. Review of the literature suggests that treatment with SSRIs or SNRIs reduces the frequency and severity of hot flashes in menopausal and post-menopausal women. Studies demonstrated that paroxetine (Paxil), citalopram (Celexa) and escitolapram (Lexapro) were the most effective SSRIs, and venlafaxine (Effexor) was the most effective first line SNRI, with desvenlafaxine as a second option. The most common side effects reported for both SSRIs and SNRIs are nausea and constipation, with most resolving within the first week of treatment. SNRIs have been associated with increased blood pressure in some patients and should be used with caution in women with hypertension. Women with a history of breast cancer and taking tamoxifen should avoid SSRIs, which have been shown to interfere with tamoxifen metabolism. SNRIs are the safest drugs for this population. Treatment choice should be patient-specific and begin with the lowest dose available. LEVEL OF EVIDENCE FOR THE ANSWER: A. SEARCH TERMS: SSRI, SNRI, hot flashes, vasomotor symptoms, menopause. SEARCH CONDUCTED: August 2014, February 2016 and August 2016. INCLUSION CRITERIA: menopausal, perimenopausal or postmenopausal women 18 years of age or older with frequent and/or severe vasomotor symptoms, meta-analyses, systematic reviews, randomized controlled trials, cohort studies. EXCLUSION CRITERIA: pre-menopause, anxiety, depression, panic disorder, bipolar disorder, co-morbid conditions.

RESUMO

CLINICAL QUESTION: In adults with acute plantar fasciitis whose symptoms have not been relieved with the conventional regimen of NSAIDS, stretching and lifestyle modification, do the addition of orthotics (prefabricated or custom fitted) reduce pain and improve function compared with other non-surgical treatments (manipulative chiropractic, physical therapy and/or heel steroid injections)? ANSWER: Yes. Studies have shown that orthotics, both prefabricated and custom fitted, reduce pain and improve function in adults with acute plantar fasciitis with few risks or side effects. Used alone or in addition to conventional therapy (NSAIDs, stretching, lifestyle modification), orthotics are effective and well tolerated by patients for short-term pain relief and improved function. Prefabricated orthotics are less costly and provide similar relief to more expensive custom orthotics. Level of Evidence of the Answer: A Search Terms: Plantar fasciitis, heel pain, treatment, orthotics, Limits: Adult, human, English, Review, Randomized-Control Trials, Systematic Reviews, adults age 18 or more, publication dates 2004 to present. Date Search was Conducted: January 16, 2014; updated January 20, 2015 INCLUSION CRITERIA: Recent published systematic reviews, randomized controlled, meta-analyses; adults with confirmed acute or recent diagnosis of plantar fasciitis. EXCLUSION CRITERIA: Studies older than 10 years, children, adolescents less than 18 years of age, chronic or recalcitrant plantar fasciitis.

RESUMO

UNLABELLED: RESIDENCY PROGRAM: University of Oklahoma Health Sciences Center, Department of Family and Preventive Medicine, Oklahoma City, OK. ANSWER: In patients with suspected OSA, it is reasonable to use PMs if the patient has a high pretest probability (based on an Epworth Sleepiness Scale (ESS) ≥10 and clinical symptoms*) without significant co-morbid heart disease or other sleep disorders and he/she is able to prove competency in setting up the home equipment properly without assistance. However, if the patient has a negative PM, it is standard to perform PSG as it appears approximately 20% will have a false negative PM. (*Clinical symptoms include snoring, witnessed apneas, obesity, pulmonary hypertension, refractory hypertension, morning headaches, increased neck circumference-->17 inches in men, >16 inches in women--daytime sleepiness.) LEVEL OF EVIDENCE FOR THE ANSWER: A. SEARCH TERMS: obstructive sleep apnea, polysomnography, portable home monitors, efficacy. INCLUSION CRITERIA: polysomnography, ambulatory, adults, humans. ESCLUSION CRITERIA: children.

RESUMO

A 19-month-old boy was evaluated for a skin eruption after recent vaccinations. Clinical and histopathologic findings supported a diagnosis of Gianotti-Crosti syndrome (GCS). This case report examines the link between GCS and vaccinations, particularly the diphtheria, tetanus, and pertussis vaccine and the varicella virus live vaccine.

RESUMO

A 14-year-old girl presented with a 3-week history of mucosal erosions, injected conjunctiva, dehydration, and respiratory distress. She had been treated with intravenous acyclovir for herpes simplex infection with positive herpes simplex virus immunoglobulin M and immunoglobulin G. Physical examination and imaging revealed a large abdominal mass. Incisional biopsy was obtained, and pathology demonstrated angiofollicular hyperplasia with hyalinized germinal centers and Castleman's syndrome-like features. Based on the mucosal erosions, herpes simplex virus serology and positive herpes simplex virus-1 direct fluorescent antibody, Castleman's disease secondary to overwhelming herpes simplex virus infection was the initial impression. The poor response to antivirals and subsequent development of a bullous eruption on the hands resulted in dermatology consultation. Skin biopsy was obtained from a bullae and revealed suprabasilar acantholysis with necrosis as well as upper dermal, perivascular, and interface infiltrate of lymphocytes and eosinophils. No viropathic changes were present. Direct immunofluorescence was significant for immunoglobulin G deposition intercellularly and along the dermoepidermal junction and focal trace C3 deposition along the dermoepidermal junction consistent with paraneoplastic pemphigus, later confirmed by indirect immunofluorescence. We report this case of paraneoplastic pemphigus secondary to Castleman's syndrome confounded by herpes simplex virus-1 positive mucosal erosions.

RESUMO

In recent decades, the rate of introduction of non-indigenous macroalgae has increased. While invasive seaweeds often outcompete native species for substrata, their direct effects on marine life are rarely described. Here, we describe 'red water' events caused by the decay of blooms of the invasive red seaweed, Dasysiphonia japonica, in Great South Bay, NY, USA, and the ability of water from such events to induce rapid and significant mortality in larval and juvenile fish (Menidia beryllina, Menidia menidia, and Cyprinodon variegatus) and larval bivalves (Mercenaria mercenaria and Crassostrea virginica). All species studied experienced significant (p<0.05) reductions in survival when exposed to macroalgae in a state of decay, seawater in which the alga was previously decayed, or both. Both bivalve species experienced 50-60% increases in mortality when exposed to decaying D. japonica for ∼ one week, despite normoxic conditions. Among fish, significant increases (40-80%) in mortality were observed after 24 h exposure to decayed D. japonica and one-week exposures caused, on average, 90% mortality in larval M. beryllina, 50% mortality in juvenile (∼3 cm) M. menidia, and 50% mortality in larval C. variegatus. All fish and bivalve mortality occurred under normoxic conditions (dissolved oxygen (DO) >7 mg L-1) and low ammonium levels (< 20 µM), with the exception of C. variegatus, which expired under conditions of decayed D. japonica coupled with reduced DO caused by the alga. Screening of water with decayed D. japonica using liquid chromatography-mass spectrometry revealed compounds with mass-to-charge ratios matching caulerpin, a known algal toxin that causes fish and shellfish mortality, and several other putative toxicants at elevated levels. Collectively, the high levels of mortality (50-90%) of larval and juvenile fish and bivalves exposed to decaying D. japonica under normoxic conditions coupled with the observation of 'red water' events in estuaries collectively indicate the red seaweed, D. japonica, can create harmful algal blooms (HABs).

RESUMO

Lower limb overuse injuries are common among people who are exposed to physical stress. Orthotic shoe insoles are widely used to prevent lower limb overuse injuries. Here, we conducted a randomized-controlled study to examine whether the use of orthotic insoles prevents lower limb overuse injuries. Participants (n=228) were randomly assigned to use (n=73) or not to use (n=147) orthotic insoles. The insoles were molded to the shape of the foot to provide support during physical activity. The main outcome measure in the present study was the physician-diagnosed lower limb overuse injury. Thirty-four (46.6%) subjects in the insole group were diagnosed with a lower limb overuse injury compared with 56 (38.1%) in the control group (P=0.29) during the 6-month study period. When body mass index and the results of a 12-min running test and muscle strength were adjusted in a Cox's regression model, the hazard ratio for lower limb overuse injury in the insole group was 1.3 (95% confidence intervals: 0.8-2.1) compared with the control group. Use of orthotic insoles was not associated with a decrease in lower limb overuse injuries. Our findings suggest that routine use of orthotic insoles does not prevent physical-stress-related lower limb injuries in healthy young male adults.

RESUMO

This study sought to identify barriers to treatment in children with chronic inflammatory skin disease, particularly those with atopic dermatitis, psoriasis, and acne vulgaris. Caregivers of 101 patients seen in the Children's Specialty Group Division of Dermatology, Children's Hospital of The King's Daughters, Norfolk, Virginia, completed an 11-item Likert scale questionnaire. This survey addressed complexity and time requirements for treatment, medication cost, vehicle formulation, perceived safety, and caregiver understanding of chronicity of skin disorders. Parents and caregivers indicated that adequate instructions for using the medications were provided but that they felt less comfortable with treating their child's skin disease during a severe flare. The complexity of treatment programs, time required to apply medications, and vehicle type were not considered prohibitive factors. Caregivers were concerned about the cost and safety of prescribed medications and had a less understanding of the chronicity of inflammatory skin disorders.

RESUMO

BACKGROUND AND AIMS: The interpositional arthroplasty was developed to retain foot function and to relieve pain due to the arthritis of the first metatarsophalangeal joint. The bioabsorbable poly-L-D-lactic acid RegJoint® interpositional implant provides temporary support to the joint, and the implant is subsequently replaced by the patient's own tissue. In this study, we retrospectively examined the results of the poly-L-D-lactic acid interpositional arthroplasty in a 9-year follow-up study among patients with hallux valgus with end-stage arthrosis or hallux rigidus. MATERIAL AND METHODS: Eighteen patients and 21 joints underwent interpositional arthroplasty using the poly-L-D-lactic acid implant between February 1997 and October 2002 at Tampere University Hospital. Of these, 15 (83.3%) (21 joints) patients were compliant with clinical examination and radiographic examination in long-term (average 9.4 years) follow-up. The mean age of the patients was 48.3 (from 28 to 67) years at the time of the operation. Six patients underwent the operation due to arthritic hallux valgus and nine patients due to hallux rigidus. RESULTS: The mean Ankle Society Hallux Metatarsophalangeal-Interphalangeal Scale and visual analogue scale (VAS) for pain scores improved after the operation in all patients. The decrease of pain (visual analogue scale) after the operation was statistically significant (77.5 vs 10.0; p < 0.001). Postoperative complications were observed in 3 (14.3%) joints of two hallux rigidus patients. For these patients, surgery had only temporarily relieved the pain, and they underwent reoperation with arthrodesis. CONCLUSION: In conclusion, interpositional arthroplasty using a poly-L-D-lactic acid implant yielded good results. This study indicates that the poly-L-D-lactic acid interpositional implant may be a good alternative for arthrodesis for treatment of end-stage degeneration of the first metatarsophalangeal joint.

RESUMO

Our objective was to compare the efficacy of selenium sulfide shampoo 1% and ciclopirox shampoo 1% as adjunctive treatments for tinea capitis in children. Forty children aged 1-11 years with clinically diagnosed tinea capitis were randomized to receive selenium sulfide shampoo 1% or ciclopirox shampoo 1% twice a week as adjuncts to an 8-week course of ultramicronized griseofulvin dosed at 10-12 mg/kg/day. At weeks 2, 4, and 8, subjects returned to the clinic for evaluation and scalp cultures. Subjects then returned for follow-up visits 4 weeks after completing treatment. Overall, by 8 weeks, 30 of 33 (90.9%) treated children demonstrated mycological cure. Selenium sulfide shampoo 1% and ciclopirox shampoo 1% were equally effective as adjunctive treatments for tinea capitis in children in our study.

RESUMO

Cutaneous manifestations of congenital herpes simplex virus (HSV) have been classically described as grouped vesicles on an erythematous base. We report two cases of HSV infection wherein both infants presented at birth with widespread erosions and an absence of vesicles or vesicopustules. The presence of skin lesions at birth, neurologic changes seen on radiographic imaging, and a cesarean section delivery in one case suggests intrauterine transmission in both neonates.

RESUMO

We tested the hypothesis that endothelium-dependent vasodilatation is a determinant of insulin resistance of skeletal muscle glucose uptake in human obesity. Eight obese (age 26+/-1 yr, body mass index 37+/-1 kg/m2) and seven nonobese males (25+/-2 yr, 23+/-1 kg/m2) received an infusion of bradykinin into the femoral artery of one leg under intravenously maintained normoglycemic hyperinsulinemic conditions. Blood flow was measured simultaneously in the bradykinin and insulin- and the insulin-infused leg before and during hyperinsulinemia using [15O]-labeled water ([15O]H2O) and positron emission tomography (PET). Glucose uptake was quantitated immediately thereafter in both legs using [18F]- fluoro-deoxy-glucose ([18F]FDG) and PET. Whole body insulin-stimulated glucose uptake was lower in the obese (507+/-47 mumol/m2 . min) than the nonobese (1205+/-97 micromol/m2 . min, P < 0.001) subjects. Muscle glucose uptake in the insulin-infused leg was 66% lower in the obese (19+/-4 micromol/kg muscle . min) than in the nonobese (56+/-9 micromol/kg muscle . min, P < 0.005) subjects. Bradykinin increased blood flow during hyperinsulinemia in the obese subjects by 75% from 16+/-1 to 28+/-4 ml/kg muscle . min (P < 0.05), and in the normal subjects by 65% from 23+/-3 to 38+/-9 ml/kg muscle . min (P < 0.05). However, this flow increase required twice as much bradykinin in the obese (51+/-3 microg over 100 min) than in the normal (25+/-1 mug, P < 0.001) subjects. In the obese subjects, blood flow in the bradykinin and insulin-infused leg (28+/-4 ml/kg muscle . min) was comparable to that in the insulin-infused leg in the normal subjects during hyperinsulinemia (24+/-5 ml/kg muscle . min). Despite this, insulin-stimulated glucose uptake remained unchanged in the bradykinin and insulin-infused leg (18+/-4 mumol/kg . min) compared with the insulin-infused leg (19+/-4 micromol/kg muscle . min) in the obese subjects. Insulin-stimulated glucose uptake also was unaffected by bradykinin in the normal subjects (58+/-10 vs. 56+/-9 micromol/kg . min, bradykinin and insulin versus insulin leg). These data demonstrate that obesity is characterized by two distinct defects in skeletal muscle: insulin resistance of cellular glucose extraction and impaired endothelium-dependent vasodilatation. Since a 75% increase in blood flow does not alter glucose uptake, insulin resistance in obesity cannot be overcome by normalizing muscle blood flow.

RESUMO

Essential hypertension is characterized by skeletal muscle insulin resistance but it is unknown whether insulin resistance also affects heart glucose uptake. We quantitated whole body (euglycemic insulin clamp) and heart and skeletal muscle (positron emission tomography and 18F-fluoro-2-deoxy-D-glucose) glucose uptake rates in 10 mild essential hypertensive (age 33 +/- 1 yr, body mass index 23.7 +/- 0.8 kg/m2, blood pressure 146 +/- 3/97 +/- 3 mmHg, VO2max 37 +/- 3 ml/kg per min) and 14 normal subjects (29 +/- 2 yr, 22.5 +/- 0.5 kg/m2, 118 +/- 4/69 +/- 3 mmHg, 43 +/- 2 ml/kg per min). Left ventricular mass was similar in the hypertensive (155 +/- 15 g) and the normotensive (164 +/- 13 g) subjects. In the hypertensives, both whole body (28 +/- 3 vs 44 +/- 3 mumol/kg per min, P < 0.01) and femoral (64 +/- 11 vs 94 +/- 8 mumol/kg muscle per min, P < 0.05) glucose uptake rates were decreased compared to the controls. In contrast, heart glucose uptake was 33% increased in the hypertensives (939 +/- 51 vs 707 +/- 46 mumol/kg muscle per min, P < 0.005), and correlated with systolic blood pressure (r = 0.66, P < 0.001) and the minute work index (r = 0.48, P < 0.05). We conclude that insulin-stimulated glucose uptake is decreased in skeletal muscle but increased in proportion to cardiac work in essential hypertension. The increase in heart glucose uptake in mild essential hypertensives with a normal left ventricular mass may reflect increased oxygen consumption and represent an early signal which precedes the development of left ventricular hypertrophy.
