The mechanisms of skin breakdown induced by incontinence have been proposed from a variety of experimental studies. However, studies on the influence of skin properties caused by incontinence of bedridden subjects are very limited. This work was conducted to reveal how incontinence influences skin properties by comparing bedridden incontinent elderly subjects with age-matched healthy continent elderly and middle-aged subjects. Bedridden incontinent elderly subjects (n = 35, 83.5 ± 9.7 years, mean age ± SD), healthy continent elderly (n = 41, 75.9 ± 5.6 years), and middle-aged (n = 20, 41.3 ± 2.8 years) were recruited for this study. Skin surface pH, capacitance/hydration, transepidermal water loss, and bacteria on forearm and buttock skin were measured. Hydration and transepidermal water loss values between healthy elderly subjects and incontinent elderly subjects were significantly different on buttock skin. Significant differences between those two groups were also observed regarding pH and total bacteria levels on buttock skin. The forearm skin showed no significant difference in these parameters. No significant influence was observed between with and without urination at the measurement time except for the pH of buttock skin. No significant correlation was observed except between pH and bacteria levels on buttock skin of incontinent elderly subjects. In this study, we clarified the characteristic features of skin induced by incontinence. Our results indicate that these parameters are adequate not only to evaluate the characteristic skin features of bedridden incontinent subjects but also to develop new diapers to avoid the diaper dermatitis caused by incontinence. © 2015 The International Society of Dermatology.

Analytical review of 664 cases of penetrating buttock trauma

PubMed Central

2011-01-01

A comprehensive review of data has not yet been provided as penetrating injury to the buttock is not a common condition accounting for 2-3% of all penetrating injuries. The aim of the study is to provide the as yet lacking analytical review of the literature on penetrating trauma to the buttock, with appraisal of characteristics, features, outcomes, and patterns of major injuries. Based on these results we will provide an algorithm. Using a set of terms we searched the databases Pub Med, EMBASE, Cochran, and CINAHL for articles published in English between 1970 and 2010. We analysed cumulative data from prospective and retrospective studies, and case reports. The literature search revealed 36 relevant articles containing data on 664 patients. There was no grade A evidence found. The injury population mostly consists of young males (95.4%) with a high proportion missile injury (75.9%). Bleeding was found to be the key problem which mostly occurs from internal injury and results in shock in 10%. Overall mortality is 2.9% with significant adverse impact of visceral or vascular injury and shock (P < 0.001). The major injury pattern significantly varies between shot and stab injury with small bowel, colon, or rectum injuries leading in shot wounds, whilst vascular injury leads in stab wounds (P < 0.01). Laparotomy was required in 26.9% of patients. Wound infection, sepsis or multiorgan failure, small bowel fistula, ileus, rebleeding, focal neurologic deficit, and urinary tract infection were the most common complications. Sharp differences in injury pattern endorse an algorithm for differential therapy of penetrating buttock trauma. In conclusion, penetrating buttock trauma should be regarded as a life-threatening injury with impact beyond the pelvis until proven otherwise. PMID:21995834

The vascular effects of isoxsuprine, diazoxide, and isoproterenol were studied in arterial buttock flaps and latissimus dorsi myocutaneous flaps in pigs. Capillary blood flow to the skin and muscles of these flaps was measured by the radioactive microsphere (15-mu diameter) technique 6 hours postoperatively under pentobarbital anesthesia. It was observed that isoproterenol, a beta-adrenergic receptor agonist, was not effective in augmentation of skin blood flow in the arterial buttock flaps. However, isoproterenol significantly increased capillary blood flow to the arterialized portion of latissimus dorsi myocutaneous flaps compared with controls. Isoxsuprine and diazoxide (vascular smooth muscle relaxants) significantly (p less thanmore » 0.05) increased total capillary blood flow to the skin of arterial buttock flaps and to the skin and muscles of the latissimus dorsi myocutaneous flaps. However, the increase in capillary blood flow occurred mainly in the arterialized portion of these flaps. The capillary blood flow, which was supplied by the small arteries in the distal portion of the arterial buttock and latissimus dorsi flaps, was not increased by treatment with isoxsuprine or diazoxide. Therefore, there was also no increase in the maximum distance of capillary blood flow from the pedicle to the distal end of the flaps. These observations led the authors to hypothesize that different sizes (diameters) of arteries in the skin and muscle have different reactivity (or sensitivity) to vasodilatory drugs. In the present experiment, the large dominant artery of the arterial buttock and latissimus dorsi flaps responded to isoxsuprine or diazoxide (vascular smooth-muscle relaxants), resulting in an increase in blood supply to the capillaries in the proximal portion of the flaps.« less

Fat transfer and fatal macroembolization.

Astarita, Denis C; Scheinin, Lisa A; Sathyavagiswaran, Lakshmanan

2015-03-01

Fat embolism is usually associated with long bone fractures or other trauma. The diagnosis is usually clinical, and in most cases, emboli are not fatal and not usually seen on gross examination. At the Los Angeles County Coroner's Office, we autopsied the victim of fatal macroscopic fat embolization to the lungs. The patient died during buttock enhancement surgery when fat from liposuction was injected into her buttocks. Fat embolism from liposuction and fat injection is reportedly rare, and macroscopic embolization is rarer still. Varicose veins can occur in the area of the sciatic notch and are known to cause painful sciatica symptoms. We suggest them as a potential conduit for macroscopic fat to reach the lungs. Simple pre-operative questioning for sciatica symptoms and possible radiologic study to rule out sciatic varices seem prudent before undertaking buttock-enhancing surgery. Careful fat injection with pre-aspiration is always advised. © 2015 American Academy of Forensic Sciences.

Among service members injured in Iraq and Afghanistan, to determine the risk of mortality associated with combat-related burns to the genitalia, perineum, and buttocks. The prospectively maintained burn registry from the United States Army Institute of Surgical Research was retrospectively reviewed to identify all service members with combat-related burns sustained in Iraq and Afghanistan from March 2003 to October 2013. The two primary risk factors of interest were (1) any burn to the genitals, perineum, and/or buttocks (PB) and (2) burns involving the entire perineal, genital, and buttock region (complete PB). Cox proportional hazard models were used to estimate the risk of mortality for both primary risk factors, and adjusted for severe non-burn-related trauma, percent of burn over total body surface area (TBSA), inhalational injury, time to urinary tract infection, and time to bacteremia. A post-hoc analysis was performed to explore the potential effect modification of TBSA burned on the relationship between PB and mortality. Among the 902 U.S. service members with combat-related burns sustained during the study period, 226 (25.0%) had involvement of the genitalia, perineum, and/or buttocks. Complete PB was associated with a crude risk of mortality (HR: 5.3; 2.9-9.7), but not an adjusted risk (HR=1.8; 0.8-4.0). However, TBSA burned was identified as a potential negative effect modifier. Among patients with burns <60% TBSA, sustaining a complete PB conferred an adjusted risk of death (HR=2.7; 1.1-6.8). Further, patients with a perineal burn had a five-fold increased incidence of bacteremia. In adjusted models, each event of bacteremia increased the risk of mortality by 92% (HR 1.92; 1.39-2.65). Perineal burns were associated with a two-fold increased incidence of severe non-burn related trauma that also doubled mortality risk in adjusted models (HR 2.29; 1.23-4.27). Among those with relatively survivable combat-related burns (<60% TBSA), genital/perineal/buttock involvement increases the risk of death. Bacteremia may account for part of this increased risk, but does not fully explain the independent risk associated with perineal burns. Published by Elsevier Ltd.

1) To determine the negative predictive value (VPN) of duplex scan in patients complaining of buttock or hip pain and thereby to distinguish vascular claudication from other musculoskeletal or neurological diseases. 2) To show its complementarity in doppler investigation of lower limb arteries. Prospective study by duplex scan and arteriography of 60 gluteal arteries in 30 consecutive patients referred to check up for lower limb arteriopathy or sexual impotence. Duplex scan was performed by posterior approach. Correlation between doppler ultrasound and arteriography was studied. The study of normal arteries was possible in all cases and only one normal gluteal artery could not be detected in a diabetic overweight patient. On 60 arteries, sensitivity of duplex was 100 percent, specificity 96 percent and VPN 100 percent. Significant obstructive lesions were always associated with pathological velocimetric waveform or were not detected. Buttock claudication can appear like a typical vascular claudication or mimic neurological or musculoskeletal diseases. It is very useful to rule out a vascular causality responsible for buttock or hip pain by simple, non-invasive and cheap exploration. A normal doppler ultrasound of gluteal arteries can rule out vascular disease responsible for buttock or hip pain thereby avoiding arteriography. The strategy of diagnostic or therapy can be modified by such additional information as shown in two case reports.

Preventing fall-related vertebral fractures: effect of floor stiffness on peak impact forces during backward falls.

In vivo biomechanical study of 11 male volunteers. To measure the peak forces applied to the buttocks in a backward fall from standing, and to determine whether this force is lowered by reductions in floor stiffness. Fall-related vertebral fractures are common and backward falls result in impact to the buttocks. Compliant flooring may reduce impact force and risk for vertebral fracture during a fall. However, we have little knowledge of the peak forces applied to the body during a backward fall, or how floor stiffness affects this force. Eleven males, mean age 25 +/- 5 (SD) years, were suddenly released from a backward lean of 15 degrees , falling backward onto the ground which was covered with 4.5, 7.5, or 10.5 cm of ethylene vinyl acetate foam rubber. We measured 3-dimensional impact forces applied to the buttocks at 960 Hz with a force plate. We used repeated measures analysis of variance and post hoc t tests to compare peak forces between conditions. We also modeled peak vertical force for falls onto a bare floor. RESULTS.: There was a significant difference in peak vertical force between falls onto the 10.5 cm foam condition compared with the 7.5 cm (P = 0.002) and 4.5 cm (P < 0.001) conditions. Peak vertical force (N) was (mean +/- SD) 5099 +/- 868, 4788 +/- 702, and 4544 +/- 672 for the 4.5, 7.5, and 10.5 cm foam conditions, respectively, and estimated at 6027 +/- 988 for the rigid (bare floor) condition. Compared with the bare floor, these foam floors provided, on average, 24, 20, and 15% force attenuation respectively. In a backward fall onto the buttocks, peak impact forces are 6.4 to 9.0 times body weight in a fall onto a bare floor. Reducing floor stiffness using even a thin (4.5 cm) layer of foam may provide 15% vertical force attenuation during a fall onto the buttocks.

Hypogastric artery (HA) revascularization during endovascular aneurysm repair (EVAR) is still open to debate. Moreover, exclusion-related complication rates reported in literature are not negligible. The aim of this study is to present and analyze the outcomes in patients undergoing EVAR with exclusion of 1 or both HAs at our academic center. We retrospectively reviewed our results in patients submitted to EVAR and needing HA exclusion, in terms of perioperative (30-day) and follow-up rates of intestinal and spinal cord ischemia, buttock claudication, buttock skin necrosis, and sexual dysfunction. From January 2008 to December 2014, a total of 527 patients underwent elective standard infrarenal EVAR; among those 104 (19.7%) had iliac involvement needing HA exclusion. In 73 patients with unilateral iliac involvement (70.1%, group UH), many single HAs were excluded. Thirty-one patients (29.9%) had bilateral iliac involvement (group BH), of which 16 (51.6%) had 1 HA excluded with revascularization of the contralateral one (group BHR); in the remaining 15 patients (48.4%) both HAs were excluded (group BHE). No 30-day or follow-up aneurysm-related mortality, intestinal, or spinal cord ischemia were recorded. At 30 days, skin necrosis was observed in 2 patients. Buttock claudication and sexual dysfunction rates were significantly greater in group BHE than in group BHR (P < .05). At a mean 18.6 months follow-up (range: 4-47), buttock claudication and sexual dysfunction rates in group BHE were persistently higher than that in groups UH and BHR (P < .05); HA coil embolization was significantly associated with buttock claudication and sexual dysfunction (P < .05). Whenever anatomically feasible, at least 1 HA should be salvaged in case of bilateral involvement. In case of unilateral HA exclusion, the rate of complications is not negligible. Coil embolization is related to a higher complication rate. © The Author(s) 2016.

Though typically involving the lower extremities, elephantiasis nostras verrucosa (ENV) can occur in any area affected by lymphedema. Here we report two cases of ENV: one is a biopsy-proven case and the other is a clinically diagnosed case. Both occurred on the buttocks and sacrum of immobile, morbidly obese men who were persistently in the supine or seated position. Whereas classic ENV is not uncommon, this striking presentation on these unusual areas is quite rare.

Abstract Background: Skin laxity and cellulite on the buttocks and thighs are two common cosmetic concerns. Skin tightening with radiofrequency (RF) devices has become increasingly popular. The purpose of this study is to evaluate the efficacy and safety of a topical skin laxity tightening agent when used in combination with an RF device. A double-blinded, randomized clinical trial enrolled twenty females with mild-to-moderate skin laxity on the posterior thighs/buttocks. Each subject underwent two monthly treatments with an RF source (Alma Accent) to both legs. Subjects were then randomized to apply a topical agent (Skinceuticals Body Tightening Concentrate) twice daily to only one designated thigh/buttock throughout the eight-week duration of the study. All subjects were evaluated for improvement in lifting, skin tone, radiance, firmness/tightness, skin texture, and overall appearance based on photographic evaluation by blinded investigators at 12 weeks following the final RF treatment. A statistically significant improvement was found in the overall appearance on both sides treated with the RF device when compared to baseline. However, the area treated with the topical agent showed a statistically significantly greater degree of improvement than the side where no topical agent was applied. No adverse effects were reported. The use of a novel skin tightening agent used after RF procedures is both safe and effective for treatment of skin laxity on the buttocks and thighs. Combined therapy leads to a better result.

Tristimulus colorimetry, which uses the Commission Internationale de l'Eclairage L*a*b* model to quantify color, has previously been used to analyze pigmentation and erythema in human skin; however, colorimetry of African American skin is not well characterized. We sought to analyze skin color patterns in African Americans and compare them with those of Caucasians. Colorimetry readings of the sun-protected buttock and sun-exposed back of forearm were taken from 40 Caucasian and 43 African American participants from March 2011 through August 2015. African American participants also completed a lifestyle questionnaire. Correlation coefficients, paired t tests, and multivariable linear regression analyses were used for statistical comparisons. Forearm skin was lighter in African Americans ages 65 years and older versus 18 to 30 years (P = .02) but darker in Caucasians ages 65 years or older versus 18 to 30 years (P = .03). In African Americans ages 18 to 30 years, the buttock was darker than the forearm (P < .001), whereas in Caucasians the buttock was lighter than the forearm (P < .001). A lighter forearm than buttock was correlated with supplement use, smoking (ages 18-30 years), and less recreational sun exposure (ages ≥65 years) in African Americans. Our study was limited by the sample size and focal geographic source. Pigmentation patterns regarding sun-protected and sun-exposed areas in African Americans may differ from that of Caucasians, suggesting that other factors may contribute to skin pigmentation in African Americans.

Sacrospinous colpopexy is an effective vaginal apical support operation. Due to morbidity associated with traditional approaches which require wide dissection, slim-line suture delivery devices have been introduced in the hope of reducing morbidity without compromise to outcomes. The aim of our series was to report outcomes and complications (particularly buttock pain and blood loss) of the sacrospinous colpopexy using the Capio suturing device and evaluate it against published results using the Miya hook. This is a prospective, multi-centre descriptive study. The primary outcome is objective success at 12 months. Secondary outcomes include subjective success at 12 months, patient-reported outcomes at 12 months, operating time, estimated blood loss and post-operative buttock pain. Fifty-one consenting patients undergoing sacrospinous colpopexy were recruited at four Queensland hospitals. Objective success at 12 months was 95% (41/43) and subjective success at 12 months was 92% (44/48). Eighty-four percent of patients reported buttock pain at one week, reducing to 16% by six weeks, of which 7% required analgesia. At a mean of 17 months follow up, we found that the sacrospinous colpopexy using the Capio suturing device provided excellent apical support with a low requirement for blood transfusion and an average operating time of seven minutes. We found a high rate of buttock pain immediately post-operatively, but our rates became consistent with previous reports by six weeks post-operation. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Prevention of pressure sores remains a significant problem confronting spinal cord injury patients and the elderly with limited mobility. One vital aspect of this subject concerns the development of cushions to decrease pressure ulcers for seated patients, particularly those bound by wheelchairs. Here, we present a novel cushion system that employs interface pressure distribution between the cushion and the buttocks to design custom contoured foam cushion. An optimized normalization algorithm was proposed, with which interface pressure distribution was transformed into the carving depth of foam cushions according to the biomechanical characteristics of the foam. The shape and pressure-relief performance of the custom contoured foam cushions was investigated. The outcomes showed that the contoured shape of personalized cushion matched the buttock contour very well. Moreover, the custom contoured cushion could alleviate pressure under buttocks and increase subjective comfort and stability significantly. Furthermore, the fabricating method not only decreased the unit production cost but also simplified the procedure for manufacturing. All in all, this prototype seat cushion would be an effective and economical way to prevent pressure ulcers.

Interaction between tumour survival tactics and anti-tumour immune response is a major determinant for cancer growth. Regulatory T cells (T-regs) contribute to tumour immune escape, but their role in basal cell carcinoma (BCC) is not understood. The fraction of T-regs among T cells was analysed by immunohistochemistry followed by automated image analysis in facial BCC, peritumoural skin and normal, buttock skin. Quantitative real-time PCR (qRT-PCR) was performed for FOXP3 and cytokines involved in T-reg attraction and T-cell activation. T-regs comprised 45% of CD4-cells surrounding BCC. FOXP3 was highly expressed in BCC, but absent in buttock skin. Unexpectedly, expression of FOXP3 was increased in peritumoural skin, with the FOXP3/CD3 fractions exceeding those of BCC (p?=?0.0065). Transforming growth factor (TGF)-? and T-reg chemokine expression was increased in BCC and peritumoural skin, but not in buttock skin, with expression levels correlating with FOXP3. T-regs are abundantly present both in BCC and in peritumoural skin, mediating an immunosuppressed microenvironment permissive for skin cancer.

Retrospective case report. A 35-year-old female presented with febrile illness and then decreased vision after repeat polymethyl methacrylate injections into her buttock muscles in Mexico. Examination was significant for retinal whitening, especially in the perifoveal areas, and intraretinal hemorrhages. Optical coherence tomography and fluorescein angiography imaging were consistent with small-vessel ischemic disease in the retina and choroid. Once systemic infection was ruled out, patient was treated with high-dose intravenous and then oral steroids. Vision recovery was good, with retinal atrophy on optical coherence tomography in the previous areas of retinal whitening. A Purtscher-like retinopathy with paracentral acute middle maculopathy and loss of vision may occur after filler injection below the neck, not just the face. This is the first report of vision loss caused by filler injected outside the face.

AG200-15 Agile Patch (AP) is a novel 7-day contraceptive patch providing ethinyl estradiol (EE) exposure comparable to low-dose combination oral contraceptives. This study determined whether application of the AP to three different anatomical sites (lower abdomen, buttock and upper torso) influences the pharmacokinetic profile of EE and levonorgestrel (LNG). In this open-label, three-period, crossover study, 24 subjects were randomized to one of six treatment sequences; each included application of patch to abdomen, buttock and upper torso, with the AP worn on one site for 7 days. After a 7-day washout, a new patch was applied to the next anatomical site. Multiple blood samples were collected up to 240 h after patch application. For plasma EE levels, median time to maximum drug concentration (Tmax, 24-48 h) and mean maximum concentration (Cmax, 47.9-61.5 pg/mL) were similar among application sites. Compared with lower abdomen, EE exposure was higher (16%-30%) at buttock and upper torso (15%-22%). For plasma LNG levels, median Tmax (72-120 h) and mean Cmax (1436-1589 pg/mL) were similar across application sites. Compared with lower abdomen, LNG exposure was higher at buttock (1%-7%) and upper torso (16%-17%). No serious adverse events (AEs) or AE-related discontinuations occurred. The most common treatment-emergent AEs were nausea, application site pruritus and headache, with frequencies comparable across anatomical sites. Absorption from the abdomen was slightly lower versus other sites; however, exposure to EE and LNG for all sites was therapeutically equivalent. The AP was well tolerated at all three anatomical sites. Copyright © 2013 Elsevier Inc. All rights reserved.

Coil embolization of the internal iliac artery (IIA) is used to extend the application of endovascular aneurysm repair (EVAR) in cases of challenging iliac anatomy. Pelvic ischemia is a complication of the technique, but reports vary as to the rate and severity. This study reports our experience with IIA embolization and compares the results to those of other published series. The vascular unit database of the Leicester Royal Infirmary was used to identify patients who had undergone IIA coil embolization prior to EVAR. Data were collected from hospital case notes and by telephone interviews. Thirty-eight patients were identified; 29 ofmore » these were contactable by telephone. A literature search was performed for other studies of IIA embolization and the results were pooled. In this series buttock claudication occurred in 55% (16 of 29 patients) overall: in 52% of unilateral embolizations (11 of 21) and 63% of bilateral embolizations (5 of 8). New erectile dysfunction occurred in 46% (6 of 13 patients) overall: in 38% of unilateral embolizations (3 of 8) and 60% of bilateral embolizations (3 of 5). The literature review identified 18 relevant studies. The results were pooled with our results, to give 634 patients in total. Buttock claudication occurred in 28% overall (178 of 634 patients): in 31% of unilateral embolizations (99 of 322) and 35% of bilateral embolizations (34 of 98) (p = 0.46, Fisher's exact test). New erectile dysfunction occurred in 17% overall (27 of 159 patients): in 17% of unilateral embolizations (16 of 97) and 24% of bilateral embolizations (9 of 38) (p = 0.33). We conclude that buttock claudication and erectile dysfunction are frequent complications of IIA embolization and patients should be counseled accordingly.« less

The relationship between skin aging and steady state ultraweak photon emission as an indicator of skin oxidative stress in vivo.

2014-08-01

Ultraweak photon emission (UPE) is one potential method to evaluate the oxidative status of the skin in vivo. However, little is known about how the daily oxidative stress of the skin is related to skin aging-related alterations in vivo. We characterized the steady state UPE and performed a skin survey. We evaluated the skin oxidative status by UPE, skin elasticity, epidermal thickness and skin color on the inner upper arm, the outer forearm, and the buttock of 70 Japanese volunteers. The steady state UPE at the three skin sites increased with age. Correlation analysis revealed that the steady state UPE only from the buttock was related to skin elasticity, which showed age-dependent changes. Moreover, analysis by age group indicated that b* values of the inner upper arm of subjects in their 20s were inversely correlated with UPE as occurred in buttock skin. In contrast, photoaged skin did not show a clear relationship with steady state UPE because the accumulation of sun-exposure might influence the sensitivity to oxidative stress. These results suggest that steady state UPE reflects not only intrinsic skin aging and cutaneous color but also the current oxidative status independent of skin aging. © 2013 John Wiley & Sons A/S.

This paper describes the application of an alternative seating concept for surgeons that reflects the research of Zen sitting postures, which require Zazen meditators to maintain fixed postures for long durations. The aim of this alternative approach is to provide sitters with a seat pan with sacral support(1) that provides a more even distribution of seat pressures, induces forward pelvic rotation and improves lumbar, buttock and thigh support. This approach was applied to the development of a chair for microscopic surgery. The experimental chair is a seat pan that closely matches the three-dimensional contours of the user's buttocks. Seat comfort was evaluated by comparing both changes in pelvic tilt and seat pressure distributions using Regionally-Differentiated Pressure Maps (RDPM) with subjective ratings of surgeons while operating in prototype and conventional chairs. Findings include that the sacral support of the prototype chair prevents backward pelvic rotation, as seen in zazen (Zen sitting postures). Preliminary data suggests that the prototype provided greater sitting comfort and support for constrained operating postures than did the conventional chair. These findings support the selective application of concave-shaped seat pans that conform to users' buttocks and reflect Zen sitting principles.

The aim of this study is to model the computational model of seated whole human body including skeleton, muscle, viscera, ligament, intervertebral disc, and skin to predict effect of the factors (sitting postures, muscle and skin, buttocks, viscera, arms, gravity, and boundary conditions) on the biodynamic characteristics of spine. Two finite element models of seated whole body and a large number of finite element models of different ligamentous motion segments were developed and validated. Static, modal, and transient dynamic analyses were performed. The predicted vertical resonant frequency of seated body model was in the range of vertical natural frequency of 4 to 7 Hz. Muscle, buttocks, viscera, and the boundary conditions of buttocks have influence on the vertical resonant frequency of spine. Muscle played a very important role in biodynamic response of spine. Compared with the vertical posture, the posture of lean forward or backward led to an increase in stress on anterior or lateral posterior of lumbar intervertebral discs. This indicated that keeping correct posture could reduce the injury of vibration on lumbar intervertebral disc under whole-body vibration. The driving posture not only reduced the load of spine but also increased the resonant frequency of spine. Copyright © 2017 John Wiley & Sons, Ltd.

Piriformis Syndrome and Endoscopic Sciatic Neurolysis.

PubMed

Knudsen, Joshua S; Mei-Dan, Omer; Brick, Mathew J

2016-03-01

Piriformis syndrome is the compression or the irritation of the sciatic nerve by the adjacent piriformis muscle in the buttock leading to symptoms that include buttock pain, leg pain, and altered neurology in the sciatic nerve distribution. Epidemiological figures of the prevalence are unknown, but are estimated to be about 12.2% to 27%. There is no consensus on the diagnostic criteria. Advancement in magnetic resonance imaging allows us to observe unilateral hyperintensity and bowing of the sciatic nerve. The pathophysiology of the disease includes single blunt trauma, overuse causing piriformis hypertrophy, and long-term microtrauma causing scarring. Treatments include physiotherapy, steroid injections, and surgery. Minimally invasive techniques are emerging with the hope that with less postoperative scar tissue formation, there will be less recurrence of the disease. In this chapter, senior author describes his technique for endoscopic sciatic neurolysis.

Background Carbon dioxide therapy, better known as carboxytherapy, relates to percutaneous infusion of medical carbon dioxide with therapeutic approaches, and its use in the treatment of localized fat has demonstrated good results. Gynoid lipodystrophy, also known as cellulite, affects 80%–90% of women after puberty, especially in the buttocks and thighs. Its etiology is complex and involves multifactorial aspects. Its treatment and evaluation require the use of new technologies (more effective and low-cost approaches). The objective was to investigate the effectiveness of carboxytherapy in the treatment of cellulite in the areas of buttocks and posterior thigh. Patients and methods Ten women, 29±6.1 years, were selected and all of them received eight treatment sessions, with an interval of 7 days between sessions. Standardized digital photographs were used to assess the severity of cellulite, and panoramic images were collected by ultrasound diagnosis. The evaluations were performed before the first treatment (baseline) and 7 days after the last treatment session of carboxytherapy. Results After the treatment, there was a significant reduction (P=0.0025) of the cellulite from degree III to degree II, and this improvement had correlation with the improvement in the organization of the fibrous lines and the disposal of adipose tissue lines of the treated regions observed through the panoramic ultrasound images diagnosis. Conclusion Carboxytherapy is an effective technique of treatment of cellulite in the buttocks region and posterior thighs of healthy women. PMID:27578994

[Purpose] The purpose of this study was to investigate the effect of the timing of leg support elevation on the horizontal force acting on the buttocks in a reclining wheelchair. [Subjects and Methods] The participants were 17 healthy men. Two experimental conditions were tested: the leg-down and leg-up conditions. The back support was reclined at increasing angles, from the initial upright position (IUP), proceeding to the fully reclined position (FRP), and returned to the upright position (RUP). The posterior inclination phase was from IUP to FRP, and the returning inclination phase was from FRP to RUP. [Results] The horizontal force under the leg-up condition was significantly higher than that under the leg-down condition in all positions of back support. [Conclusion] The leg supports should be positioned downward before reclining the back support of a wheelchair.

Sofa dermatitis.

2010-11-01

Furniture components can cause contact allergies. In the last years several cases of eczema after sofa contact have been reported. Typically the skin lesions develop on the back, the buttocks, the dorsal aspects of the thighs and arms and are often very resistant to topical corticoid therapy. Dimethylfumarate (DMF) is postulated to be the causative agent for this Type IV hypersensitivity reaction. DMF is an antimicrobial substance, which is used in asian upholstered furniture industry amongst others. We report the case of a 65-year old patient with generalised severely itching maculopapular, partly eczematous skin lesions on the buttocks, back, abdomen and arms. The resistance to therapy, several relapses after discharge from hospital as well as the detailed history lead us to the tentative diagnosis. The sofa dermatitis was proven by positive patch testing with furniture material and dimethylfumarate. © The Authors • Journal compilation © Blackwell Verlag GmbH, Berlin.

Hair today, gone tomorrow: a comparison of body hair removal practices in gay and heterosexual men.

Martins, Yolanda; Tiggemann, Marika; Churchett, Libby

2008-09-01

Although hairlessness is rapidly becoming a component of the ideal male body, little research has examined men's concerns about their body hair or their hair removal practices. Samples of gay and heterosexual men completed questionnaires that assessed whether they had ever removed their back, buttock or pubic hair, the frequency with which they did so, the methods used and their self-reported reasons for removing this hair, as well as their level of appearance investment. Results indicated that many gay and heterosexual men remove their back, buttock and pubic hair regularly and that their primary reason for doing so is to maintain or improve their appearance. The frequency of hair removal was also associated with the motivational salience component of appearance investment. The findings offer further support to the premise that gay and heterosexual men exhibit similar body image concerns.

Purpose Sacroiliac fixation using iliac screws for highly unstable lumbar spine has been reported with an improved fusion rate and clinical results. On the other hand, there is a potential for clinical problems related to iliac fixation, including late sacroiliac joint arthritis and pain. Materials and Methods Twenty patients were evaluated. Degenerative scoliosis was diagnosed in 7 patients, failed back syndrome in 6 patients, destructive spondyloarthropathy in 4 patients, and Charcot spine in 3 patients. All patients underwent posterolateral fusion surgery incorporating lumbar, S1 and iliac screws. We evaluated the pain scores, bone union, and degeneration of sacroiliac joints by X-ray imaging and computed tomography before and 3 years after surgery. For evaluation of low back and buttock pain from sacroiliac joints 3 years after surgery, lidocaine was administered in order to examine pain relief thereafter. Results Pain scores significantly improved after surgery. All patients showed bone union at final follow-up. Degeneration of sacroiliac joints was not seen in the 20 patients 3 years after surgery. Patients showed slight low back and buttock pain 3 years after surgery. However, not all patients showed relief of the low back and buttock pain after injection of lidocaine into the sacroiliac joint, indicating that their pain did not originate from sacroiliac joints. Conclusion The fusion rate and clinical results were excellent. Also, degeneration and pain from sacroiliac joints were not seen within 3 years after surgery. We recommend sacroiliac fixation using iliac screws for highly unstable lumbar spine. PMID:22318832

Ischial pressure ulcer is an important risk for every paraplegic person and a major public health issue. Pressure ulcers appear following excessive compression of buttock's soft tissues by bony structures, and particularly in ischial and sacral bones. Current prevention techniques are mainly based on daily skin inspection to spot red patches or injuries. Nevertheless, most pressure ulcers occur internally and are difficult to detect early. Estimating internal strains within soft tissues could help to evaluate the risk of pressure ulcer. A subject-specific biomechanical model could be used to assess internal strains from measured skin surface pressures. However, a realistic 3D non-linear Finite Element buttock model, with different layers of tissue materials for skin, fat and muscles, requires somewhere between minutes and hours to compute, therefore forbidding its use in a real-time daily prevention context. In this article, we propose to optimize these computations by using a reduced order modeling technique (ROM) based on proper orthogonal decompositions of the pressure and strain fields coupled with a machine learning method. ROM allows strains to be evaluated inside the model interactively (i.e. in less than a second) for any pressure field measured below the buttocks. In our case, with only 19 modes of variation of pressure patterns, an error divergence of one percent is observed compared to the full scale simulation for evaluating the strain field. This reduced model could therefore be the first step towards interactive pressure ulcer prevention in a daily set-up. Copyright © 2017 Tissue Viability Society. Published by Elsevier Ltd.

To assess the feasibility of classifying skin tone using Munsell color chart values and to compare Munsell-based skin tone categories to ethnicity/race to predict pressure ulcer risk. Pressure ulcer classification uses level of visible tissue damage, including skin discoloration over bony prominences. Prevention begins with early detection of damage. Skin discoloration in those with dark skin tones can be difficult to observe, hindering early detection. Observational cohort of 417 nursing home residents from 19 nursing homes collected between 2009-2014, with weekly skin assessments for up to 16 weeks. Assessment included forearm and buttocks skin tone based on Munsell values (Dark, Medium, Light) at three time points, ethnicity/race medical record documentation, and weekly skin assessment on trunk and heels. Inter-rater reliability was high for forearm and buttock values and skin tone. Mean Munsell buttocks values differed significantly by ethnicity/race. Across ethnicity/race, Munsell value ranges overlapped, with the greatest range among African Americans. Trunk pressure ulcer incidence varied by skin tone, regardless of ethnicity/race. In multinomial regression, skin tone was more predictive of skin damage than ethnicity/race for trunk locations but ethnicity/race was more predictive for heels. Given the overlap of Munsell values across ethnicity/race, color charts provide more objective measurement of skin tone than demographic categories. An objective measure of skin tone can improve pressure ulcer risk assessment among patients for whom current clinical guidelines are less effective. © 2016 John Wiley & Sons Ltd.

Cutaneous basal cell carcinoma (BCC) is the commonest cancer worldwide. BCC is locally invasive and the surrounding stromal microenvironment is pivotal for tumourigenesis. Cancer associated fibroblasts (CAFs) in the microenvironment are essential for tumour growth in a variety of neoplasms but their role in BCC is poorly understood. Material included facial BCC and control skin from the peritumoural area and from the buttocks. With next-generation sequencing (NGS) we compared mRNA expression between BCC and peritumoural skin. qRT-PCR, immunohistochemical and immunofluorescent staining were performed to validate the NGS results and to investigate CAF-related cyto-and chemokines. NGS revealed upregulation of 65 genes in BCC coding for extracellular matrix components pointing at CAF-related matrix remodeling. qRT-PCR showed increased mRNA expression of CAF markers FAP-α, PDGFR-β and prolyl-4-hydroxylase in BCC. Peritumoural skin (but not buttock skin) also exhibited high expression of PDGFR-β and prolyl-4-hydroxylase but not FAP-α. We found a similar pattern for the CAF-associated chemokines CCL17, CCL18, CCL22, CCL25, CXCL12 and IL6 with high expression in BCC and peritumoural skin but absence in buttock skin. Immunofluorescence revealed correlation between FAP-α and PDGFR-β and CXCL12 and CCL17. Matrix remodeling is the most prominent molecular feature of BCC. CAFs are present within BCC stroma and associated with increased expression of chemokines involved in tumour progression and immunosuppression (CXCL12, CCL17). Fibroblasts from chronically sun-exposed skin near tumours show gene expression patterns resembling that of CAFs, indicating that stromal fibroblasts in cancer-free surgical BCC margins exhibit a tumour promoting phenotype.

Microfocused Ultrasound with Visualization and Calcium Hydroxylapatite for Improving Skin Laxity and Cellulite Appearance

Background: Age-associated skin laxity contributes to worsening of cellulite appearance. This study evaluated the effects of microfocused ultrasound with visualization (MFU-V; Ultherapy) in combination with diluted calcium hydroxylapatite (CaHA; Radiesse) on cellulite appearance and on neocollagenesis. Methods: Twenty women (18–55 years old) with skin laxity and moderate-to-severe cellulite on the buttocks and thighs were retrospectively enrolled. MFU-V was applied using 4 and 7 MHz transducers (25 lines/transducer/site) and immediately followed by subdermal CaHA injection (1 ml/buttock or thigh). Photographs at baseline and 90 days were assessed by 2 independent, blinded evaluators using a 5-item cellulite severity scale. One subject scheduled for thighplasty received treatment with 6 different CaHA dilutions (0.3 ml/5 cm2) followed by MFU-V. Tissue specimens from each dilution site were examined under polarized light microscopy to assess neocollagenesis. Results: Both evaluators reported statistically significant improvements compared with baseline for each item on the cellulite severity scale (P < 0.001) with a 4.5-point improvement in mean overall score (P < 0.001) after a single MFU-V/CaHA treatment. At 90 days, histologic analysis showed peak neocollagenesis in samples treated with the 1:1 dilution, whether with CaHA alone or in combination with MFU-V. The highest conversion of collagen type III into collagen type I at month 3 occurred in samples injected with 1:1 and 1:0.6 CaHA dilutions without subsequent MFU-V treatment. Both procedures were well tolerated, and subject satisfaction was high. Conclusions: Combination treatment with MFU-V and diluted CaHA is effective for improving skin laxity and the appearance of cellulite on the buttocks and upper thighs. PMID:28831339

In the clinical diagnosis of lumbosacral radicular symptoms, dermatome maps are commonly used, by which the segmental location of the affected nerve can be determined. However, the diagnosis is often difficult because the pattern of sensory disturbance does not necessarily match the patterns of classical dermatomes, and there are many dermatome maps made by different methods. The author examined the area of pain and numbness in cases of lumbosacral radiculopathy. Clinical features of pain and numbness in consecutive seventy three cases of lumbosacral radiculopathy were investigated (L3: n=13, L4-S1: n=20). Patients of L3 radiculopathy showed symptoms at the upper buttock and ventral surface of the thighs, knees and upper ventral surface of the legs. Patients of L4 radiculopathy showed symptoms at the ventro-lateral surfaces of the thigh and leg. The distinctive region, defined as the region having 100% superimposition, of L4 radiculopathy was the lateral part of the shin. Patients of L5 radiculopathy showed symptoms at the lateral surfaces of the thigh and leg. The distinctive region was the upper buttock. Patients of S1 radiculopathy showed symptoms at the lower buttock, dorso-lateral part of the leg and lateral part of the foot. The distinctive region was the lateral part of the calf. It was found that the regions of pain and numbness formed a continuous band-like zone from thigh to leg in 8% of L3, 45% of L4 and L5, and 35% of S1 radiculopathy. Using a visual analogue scale, the degree of leg pain was more severe than low back pain in 68% of the patients, but in 5% of patients, low back pain was more severe.

Manual therapy intervention for a patient with a total hip arthroplasty revision.

Howard, Paul D; Levitsky, Beth

2007-12-01

Case report. A 73-year-old active woman with a total hip arthroplasty, who later had revision surgery, developed left hip and buttock pain 2 years after the revision surgery, subsequent to lifting her foot while seated. This movement was performed so that her spouse could assist her in putting on her sock and shoe. During the first physical therapy session, the patient exhibited a forward-flexed trunk posture and difficulty weight bearing on the involved lower limb. The patient was successfully treated with manual therapy techniques and a home exercise program. The manual therapy techniques included long-axis hip distraction, lateral hip distraction, posterior-to-anterior hip joint mobilization, and a contract-relax proprioceptive neuromuscular facilitation technique. The patient's home program consisted of long-axis hip distraction, performed by her spouse, and standing lower limb pendular movements into flexion and extension. Pain scale ratings, posture and gait observations, strength, range of motion, and return to functional activities served as outcome measures. After 1 physical therapy visit, in which manual therapy techniques were utilized, the patient had a significant decrease in hip symptoms. The patient and spouse were compliant with the home exercise program and continued with physical therapy for 3 more visits, and the patient ultimately became symptom free. The patient returned to all previous activities, including household chores, cooking, and a walking program. The patient was contacted at 6 months, 1 year, and 4 years, and reported no recurrences of hip or buttock symptoms. Manual therapy techniques and home exercises described in this case report were apparently effective in eliminating symptoms and returning this patient, who had total hip arthroplasty and revision surgery 2 years earlier, to all previous functional activities after a dressing incident produced hip and buttock symptoms.

Advancing a smart air cushion system for preventing pressure ulcers using projection Moiré for large deformation measurements

A pressure ulcer is one of the most important concerns for wheelchair bound patients with spinal cord injuries. A pressure ulcer is a localized injury near the buttocks that bear ischial tuberosity oppression over a long period of time. Due to elevated compression to blood vessels, the surrounding tissues suffer from a lack of oxygen and nutrition. The ulcers eventually lead to skin damage followed by tissue necrosis. The current medical strategy is to minimize the occurrence of pressure ulcers by regularly helping patients change their posture. However, these methods do not always work effectively or well. As a solution to fundamentally prevent pressure ulcers, a smart air cushion system was developed to detect and control pressure actively. The air cushion works by automatically adjusting a patient's sitting posture to effectively relieve the buttock pressure. To analyze the correlation between the dynamic pressure profiles of an air cell with a patient's weight, a projection Moiré system was adopted to measure the deformation of an air cell and its associated stress distribution. Combining a full-field deformation imaging with air pressure measured within an air cell, the patient's weight and the stress distribution can be simultaneously obtained. By integrating a full-field optical metrology with a time varying pressure sensor output coupled with different active air control algorithms for various designs, we can tailor the ratio of the air cells. Our preliminary data suggests that this newly developed smart air cushion has the potential to selectively reduce localized compression on the tissues at the buttocks. Furthermore, it can take a patient's weight which is an additional benefit so that medical personnel can reference it to prescribe the correct drug dosages.

Radiofrequency sensory ablation as a treatment for symptomatic unilateral lumbosacral junction pseudarticulation (Bertolotti's syndrome): a case report.

PubMed

Burnham, Robert

2010-06-01

Describe the clinical presentation, diagnostic evaluation, and successful treatment of a case of symptomatic unilateral lumbosacral junction pseudarticulation using a novel radiofrequency nerve ablation technique. A 56-year-old female patient who had suffered with low back and right upper buttock pain for 16 years experienced incomplete relief with L4/5 facet joint radiofrequency ablation. She was found to have an elongated right L5 transverse process that articulated with the sacral ala (Bertolotti's syndrome). Fluoroscopically guided local anesthetic/corticosteroid injection into the pseudarthrosis eliminated her residual right buttock pain for the duration of the local anesthetic only. Complete pain relief was achieved by injecting local anesthetic circumferentially around the posterior pseudarthrosis articular margin. Accordingly, bipolar radiofrequency strip thermal lesions were created at the same locations. Complete pain relief and full restoration of function was achieved for 16 months postprocedure. This case report describes a novel radiofrequency technique for treating symptomatic lumbosacral junction pseudarticulation that warrants further evaluation.

2016-04-01

Sacral fracture after lumbosacral instrumentation could be a source of prolonged pain and a late autonomy recovery in old patients. Diagnosis remains difficult and usually delayed. No clear consensus for efficient treatment of this complication has been defined. Aim of this study was to determine how to manage them. Three patients who sustained sacral fracture after instrumented lumbosacral fusion performed for degenerative disease of the spine are discussed. History, physical examinations' findings and radiographic features are presented. Pertinent literature was analyzed. All patients complained of unspecific low back and buttock pain a few weeks after index surgery. Diagnosis was done on CT-scan. We always choose revision surgery with good functional results. Sacral stress fracture has to be reminded behind unspecific buttock or low back pain. CT-scan seems to be the best radiological test to do the diagnosis. Surgical treatment is recommended when lumbar lordosis and pelvic incidence mismatched. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Perforator Flaps after Excision of Large Epidermal Cysts in the Buttocks

Kim, Sang Wha; Yang, Seong Hyeok; Kim, Jeong Tae

2014-01-01

Background Epidermal cysts are commonly occurring masses usually less than 5 cm in diameter, but in predisposed patients, epidermal cysts can grow relatively large due to chronic infection. Methods From June 2002 to July 2010, 17 patients received 19 regional perforator-based island flaps to cover defects due to the excision of large epidermal cysts (diameter >5 cm) in the buttocks. Eight patients had diabetes, and seven had rheumatoid arthritis. The pedicles were not fully isolated to prevent spasms or twisting. Results All the flaps survived completely, except for one case with partial necrosis of the flap, which necessitated another perforator-based island flap for coverage. There were two cases of wound dehiscence, which were re-closed after meticulous debridement. There were no recurrences of the masses during follow-up periods of 8.1 months (range, 6-12 months). Conclusions In patients with large epidermal cysts and underlying medical disorders, regional perforator-based island flaps can be the solution to coverage of the defects after excision.

Photos and/or copies of one hundred Upper Paleolithic (45,000-40,000 to 10,000 BP) statues were studied, the photos having been taken from the frontal, lateral and back view. Among the 97 female idols studied, 24 were skinny (mainly young women), 15 were of normal weight, while more than half of them (51) represented overweight or very obese females whose breasts were also extremely large. The figurine analysis revealed various types of obesity. Increased fat tissue deposition can be seen in the following body parts: belly only in 2 Venus figurines, belly + hip in 10, belly + gluteal + hip in 14, belly + hip + gluteal + femora in 24 and diffuse obesity in one. Steatopygia (derived from the Greek "steato" meaning fat, and "pygia" meaning buttocks and describing excessive fat of the buttocks) was observable in 7 idols, although these females were not particularly overweight and had a reasonably thin waist and legs. Only seven statues were in the state of advanced gravidity (pregnancy). The presence of such a small number of gravidity statuettes challenges the general view concerning Venus idols, namely, that they all represent female fertility.

Lichen planus is a common papulosquamous disorder affecting about 1-2% of the population, neoplastic transformation of cutaneous lichen planus lesions occurs very rarely. A 40 year old female patient presented with a 1 year history of developing multiple, itchy, pigmented lesions over both lower legs which gradually spread to involve the whole body. A few tense bullae were seen on the extremities. An erythematous fleshy lesion was seen on the upper aspect of the left buttock. Skin biopsy from a plaque on the right forearm showed features suggestive of lichen planus. Skin biopsy of a bullae showed a sub epidermal bulla filled with a mixed inflammatory infiltrate. Direct immunofluorescence revealed no immunoreactants along the basement membrane zone. A diagnosis of erythrodermic lichen planus with bullous lichen planus was made. Biopsy of fleshy lesion of left buttock revealed a moderately differentiated squamous cell carcinoma. Erythrodermic lichen planus with bullous lesions and secondary squamous cell carcinoma; these occurences in a single patient is extremely rare and has not been previously reported to the best of our knowledge.

The clinical significance of previously described immunoglobulin and complement deposition in the superficial dermal vessel walls of patients with rheumatoid arthritis is unknown. In the present study, skin biopsies were obtained from the normal forearm and buttock of 48 unselected patients with rheumatoid arthritis and were examined by direct immunofluorescence (IF) for the presence of immunoglobulin (IgG,A,M) and complement (C3) in the vessel walls. Deposits of C3, IgM or IgG were detected in 10 patients. Five patients had deposits at the forearm sample alone, four patients had deposits at both biopsy sites, while one patient was positive at the buttock alone. Clinical features were similar in patients with and without vessel IF. However, patients with IF were significantly more seropositive with lower levels of complement and raised levels of serum IgA and IgM. There was also an increased level of circulating IgG immune complexes in these patients. Further analysis following exclusion of seronegative patients revealed similar results. This study suggests that the presence of vessel IF identifies a subgroup of patients who have evidence of more severe immunological disturbance.

[Furuncular myiasis caused by Dermatobia hominis. Fortuitous diagnosis on extemporaneous macroscopic analysis of an excised cutaneous nodule].

PubMed

Hirsch, G; Jeandel, R; Biechler, M; Boivin, J-F; Hillion, B

2015-12-01

Furuncular myiasis is a parasitic disease caused by the development of human botfly larva in the skin. It affects people living in tropical countries and travelers returning from these countries and concerns a number of medical specialties. One form of treatment involves surgical extraction of the parasites. We report the case of a 47-year-old man returning from Guyana presenting two furuncle-like nodules of the skin on the right buttock and on the right shoulder blade. Extemporaneous intraoperative macroscopic examination of the buttock nodule resulted in diagnosis of myiasis caused by the human botfly, Dermatobia hominis. The diagnosis of furuncular myiasis is made primarily on clinical grounds and should be suspected on observation of an abscess in subjects returning from a tropical region. It is consequently rare to find D. hominis in biopsy specimens. In the present case, macroscopic examination showed an extremely rare image of the edge of the intact larva in a longitudinal cut, which to our knowledge has never been published to date.

Back and buttock pain during pregnancy and the postpartum period generally improves spontaneously and rarely causes problems. However, such pain is infrequently induced by pyogenic sacroiliitis. We herein present a 37-year-old female patient with no previous medical history who developed pyogenic sacroiliitis with severe right buttock pain 7 days after cesarean delivery. Arthrocentesis was performed, and a culture revealed the presence of methicillin-resistant Staphylococcus aureus (MRSA). After 6 weeks of treatment with intravenous antibiotics, her infection became quiescent. Eight cases of pyogenic sacroiliitis during the postpartum period and seven cases during pregnancy have been reported, but most of the causative pathogens were methicillin-sensitive Staphylococcus or Streptococcus species. This report describes the first case of postpartum pyogenic sacroiliitis caused by MRSA. The frequency of infection with MRSA has recently increased, and community-acquired MRSA, which affects even healthy young people, has also become a problem. Antibiotics for empirical therapy after a diagnosis of pyogenic sacroiliitis, including anti-MRSA antibiotics, should be carefully selected. Copyright © 2015. Published by Elsevier B.V.

Application of posterior pelvic tilt taping for the treatment of chronic low back pain with sacroiliac joint dysfunction and increased sacral horizontal angle.

2012-11-01

Kinesio Taping (KT) is a therapeutic method used by physical therapists and athletic trainers in combination with other treatment techniques for various musculoskeletal and neuromuscular problems. However, no research has evaluated the effect of KT in patients with low back pain (LBP). The purpose of this case was to describe the application of posterior pelvic tilt taping (PPTT) with Kinesio tape as a treatment for chronic LBP and to reduce the anterior pelvic tilt angle. Case report. The patien was a 20-year-old female amateur swimmer with a Cobb's angle (L1-S1) of 68°, a sacral horizontal angle of 45°, and pain in both medial buttock areas and sacroiliac joints. We performed PPTT with Kinesio tape for 2 weeks (six times per week for an average of 9 h each time). The patient’s radiographs showed that the Cobb's angle (L1-S1) had decreased from 68° to 47° and that the sacral horizontal angle had decreased from 45° to 31°. Reductions in hypomobility or motion asymmetry, as assessed by the motion palpation test, and in pain, as measured by the pain-provocation tests, were observed. On palpation for both medial buttock areas in the prone position, the patient felt no pain. The patient experienced no pain or stiffness in the low back area while performing forward flexion in the standing position with knees fully extended when washing dishes in the sink. The case study demonstrated that PPTT intervention favourably affected the pelvic inclination and sacral horizontal angle, leading to beneficial effects on sacroiliac joint dysfunction (SIJD) and medial buttock pain. Additional research on the clinical effects of this taping procedure requires greater numbers of athletes with SIJD or LBP who have inappropriate anterior pelvic tilt angles and hyperlordosis.

This study investigates the accuracy of a newly developed, next-generation subcutaneous glucose sensor, evaluated for 6-day use. Seventy-nine subjects (53 men, 26 women) with type 1 diabetes and 18 subjects (14 men, four women) with type 2 diabetes completed a three-center, prospective, sensor accuracy study. The mean age for the group was 42.2±15.0 years (mean±SD), ranging from 18 to 71 years, with a mean glycosylated hemoglobin level of 7.6±1.5%, ranging from 5.5% to 14%. Subjects wore Enlite™ sensors (Medtronic Diabetes, Northridge, CA) in the abdominal and buttocks region for two separate 7-day periods and calibrated with a home-use blood glucose meter. Subjects participated in an in-clinic testing day where frequent sampled plasma glucose samples were acquired every 15 min for 10 h. Sensor data was retrospectively processed with Guardian(®) REAL-Time (Medtronic) and Paradigm(®) Veo™ (Medtronic) calibration routines, and accuracy metrics were calculated for each algorithm and sensor location. Physiological time lag for each measurement site was calculated. Based on 6,404 plasma-sensor glucose paired points, the Enlite sensor with Veo calibration algorithm produced a mean absolute relative difference of 13.86% with 97.3% of points within the A+B zones of the Clarke error grid. Threshold-only alarms detected 90.1% of hypoglycemia and 90% of hyperglycemia. Mean time lag measured at the abdominal region was 7.94±6.48 min compared with 11.70±6.71 min (P<0.0001) at the buttocks area. The Enlite sensor accurately measures glucose when compared with gold standard laboratory measurements over its 6-day use. Sensors placed in the buttocks region exhibited greater time lags than sensors placed in the abdomen.

Classroom furniture and anthropometric characteristics of Iranian high school students: proposed dimensions based on anthropometric data.

PubMed

Dianat, Iman; Karimi, Mohammad Ali; Asl Hashemi, Ahmad; Bahrampour, Samira

2013-01-01

The study evaluated the potential mismatch between classroom furniture dimensions and anthropometric characteristics of 978 Iranian high school students (498 girls, 480 boys), aged 15-18 years. Nine anthropometric measurements (stature, sitting height, sitting shoulder height, popliteal height, hip breadth, elbow-seat height, buttock-popliteal length, buttock-knee length and thigh clearance) and five dimensions from the existing classroom furniture were measured and then compared together (using match criterion equations) to identify any potential mismatch between them. The results indicated a considerable mismatch between body dimensions of the students and the existing classroom furniture, with seat height (60.9%), seat width (54.7%) and desktop height (51.7%) being the furniture dimensions with a higher level of mismatch. The levels of mismatch varied between the high-school grade levels and between genders, indicating their special requirements and possible problems. The proposed dimensions of the classroom furniture more appropriate for the students were given. This additional information on students' anthropometry can be used by local furniture industries as a starting point for designing more appropriate furniture for school children, or used by schools to aid in furniture selection.

Objective To investigate the relieving effect on interface pressure of an alternate sitting protocol involving a sitting posture that reduces ischial support. Design Repeated measures in 2 protocols on 3 groups of subjects. Setting Laboratory. Participants Twenty able-bodied persons, 20 persons with paraplegia, and 20 persons with tetraplegia. Interventions Two 1-hour protocols were used: alternate and normal plus pushup. In the alternate protocol, sitting posture was alternated every 10 minutes between normal (sitting upright with ischial support) and with partially removed ischial support (WO-BPS) postures; in the normal plus pushup protocol, sitting was in normal posture with pushups (lifting the subject off the seat) performed every 20 minutes. Main Outcome Measure Interface pressure on seat and backrest. Results In WO-BPS posture, the concentrated interface pressure observed around the ischia in normal posture was significantly repositioned to the thighs. By cyclically repositioning the interface pressure, the alternate protocol was superior to the normal plus pushup protocol in terms of a significantly lower average interface pressure over the buttocks. Conclusions A sitting protocol periodically reducing the ischial support helps lower the sitting load on the buttocks, especially the area close to ischial tuberosities. PMID:17601466

Collagen cross-linking in sun-exposed and unexposed sites of aged human skin

NASA Technical Reports Server (NTRS)

Yamauchi, M.; Prisayanh, P.; Haque, Z.; Woodley, D. T.

1991-01-01

A recently described nonreducible, acid-heat stable compound, histidinohydroxylysinonorleucine (HHL), is a collagen cross-link isolated from mature skin tissue. Its abundance is related to chronologic aging of skin. The present communication describes the quantity of HHL from aged human skin of the same individuals in sun-exposed (wrist) and unexposed (buttock) sites. Punch biopsies were obtained from these sites from nine people of age 60 or older. HHL contents (moles/mole of collagen) at these sites were for wrist 0.13 +/- 0.07 and for buttock 0.69 +/- 0.17 (mean +/- SD, p less than 0.001). In addition, it was found that acute irradiation of the cross-linked peptides with UVA (up to 250 J/cm2) and UVB (up to 1 J/cm2) had no effect on HHL structure. The same treatment significantly degraded another nonreducible, stable collagen cross-link, pyridinoline. The results suggest that chronic sunlight exposure may be associated with an impediment to normal maturation of human dermal collagen resulting in tenuous amount of HHL. Thus, the process of photoaging in dermal collagen is different from that of chronologic aging in human skin.

Descriptive study. The objective of this study was to present anthropometric data from high school students in Cape Metropole area, Western Cape, South Africa that are relevant for chair design and whether the dimensions of computer laboratory chairs currently used in high schools match linear anthropometrics of high-school students. Summary of Background Data. Learner-chair mismatch is proposed as a cause of poor postural alignment and spinal pain in adolescents. A learner-chair mismatch is defined as the incompatibility between the dimensions of a chair and the anthropometric dimensions of the learner. Currently, there is no published research to ascertain whether the furniture dimensions in school computer laboratories match the anthropometrics of the students. This may contribute to the high prevalence of adolescent spinal pain. The sample consisted of 689 learners, 13-18 years old. The following body dimensions were measured: stature, popliteal height, buttock-to-popliteal length and hip width. These measurements were matched with the corresponding chair seat dimensions: height, depth and width. Popliteal and seat height mismatch was defined when the seat height is either >95% or <88% of the popliteal height. Buttock-popliteal length and seat depth mismatch was defined when the seat depth is either >95% or <80% of the buttock-popliteal length. Seat width mismatch is defined where the seat width should be at least 10% and at the most 30% larger than hip width. An 89% of learners did not match the seat. Five percent of learners matched the chair depth, the majority was found to be too big. In contrast, 65% of the learners matched the chair width dimension. A substantial mismatch was found. The school chairs failed standard ergonomics recommendations for the design of furniture to fit the user. This study supports the conclusion that there is no one-size-fits-all solution. There is an urgent need for chairs that are of different sizes or that are adjustable. Copyright © 2012 Elsevier Ltd and The Ergonomics Society. All rights reserved.

Chronic back pain (CBP) is frequently the presenting symptom in patients with suspected axial spondyloarthritis (axSpA). Presence of sacroiliitis on magnetic-resonance-imaging (MRI) or HLA-B27 adds to diagnostic certainty. However, these costly tests cannot be applied in all patients with CBP. This study aims to investigate which SpA features increase the likelihood of a positive HLA-B27 or positive MRI of the sacroiliac-joints (MRI-SI) in patients with suspected axSpA. Data from 665 patients with CBP within the ESPeranza Programme were analysed. Diagnostic utility measures (LR+, LR-) for a positive MRI-SI or HLA-B27 were calculated for various definitions of inflammatory back pain (IBP), their separate items and for other SpA features. Pretest probabilityies of a positive result was 41% for MRI-SI and 40% for HLA-B27. For a positive MRI-SI result the most useful IBP characteristic was alternating buttock pain (LR + =2.6). Among the IBP-criteria, fulfillment of the 'ASAS criteria' (LR + =2.1) was most contributory. Interestingly, the addition of alternating buttock pain to the Calin/ASAS-IBP criteria (LR + =6.0 and 5.5, respectively) or the addition of awakening at second half of night to the Calin-IBP criteria (LR + =5.5) increased the pre-test probability of MRI-sacroiliitis from 41% to 79-80%. Dactylitis (LR + =4.1) and inflammatory bowel disease (IBD) (LR + =6.4) increased this probability to 73% and 81%, respectively. To forecast HLA-B27 positivity, awakening at the second half of the night, fulfillment of the ASAS-IBP definition and uveitis were the most useful, but only marginally predictive (LR + = 1.3, 1,6 and 2.6, respectively). If patients with suspected axial SpA have either (1) IBP according to Calin/ASAS definition plus alternating buttock pain, or (2) IBP according to Calin definition plus awakening at night, or (3) dactylitis or 4) IBD, the probability of finding a positive MRI-SI increases significantly.

A wide variety of treatments for circumference reduction and cellulite are available, but most procedures offer suboptimal clinical effect and/or delayed therapeutic outcome. Objective To determine the safety and efficacy of the TriPollar radiofrequency device for cellulite treatment and circumference reduction. Thirty-nine females with cellulite received eight weekly TriPollar treatments. Treatment areas included the abdomen, thighs, buttocks and arms. Subjects were evaluated using standardized photographs and measurements of body weight, circumference, subcutaneous thickness, and skin elasticity of the treatment sites at baseline, immediately after and 4 weeks after the final treatment. Physicians' evaluation of clinical improvement scores using a quartile grading scale was recorded. Thirty-seven patients (95%) completed the treatment protocol. There was significant circumference reduction of 3.5 and 1.7 cm at the abdomen (P = 0.002) and thigh (P = 0.002) regions, respectively. At 4 weeks after the last treatment, the average circumferential reductions of the abdomen and thighs were sustained. No significant circumferential reductions of the buttocks and arms at the last treatment visit compared to baseline were demonstrated (P = 0.138 and 0.152, respectively). Quartile grading scores correlating to approximately 50% improvement in cellulite appearance were noted. Tripollar radiofrequency provided beneficial effects on the reduction of abdomen and thigh circumference and cellulite appearance.

To compare the clinical features of patients with sacroiliac joint (SIJ)-related sciatica-like symptoms to those with sciatica from nerve root compression and to investigate the necessity to perform radiological imaging in patients with sciatica-like symptoms derived from the SIJ. Patients with pain radiating below the buttocks with a duration of 4 weeks to 1 year were included. After physical and radiological examinations, a diagnosis of SI joint-related pain, pain due to disk herniation, or a combination of these two causes was made. Patients with SIJ-related leg pain (n = 77/186) were significantly more often female, had shorter statue, a shorter duration of symptoms, and had more often pain radiating to the groin and a history of a fall on the buttocks. Muscle weakness, corkscrew phenomenon, finger-floor distance ≥25 cm, lumbar scoliosis, positive Bragard or Kemp sign, and positive leg raising test were more often present when radiologic nerve root compression was present. Although these investigations may help, MRI of the spine is necessary to discriminate between the groups. Sciatica-like symptoms derived from the SIJ can clinically mimic a radiculopathy. We suggest to perform a thorough physical examination of the spine, SI joints, and hips with additional radiological tests to exclude other causes.

The properties of infant skin regarding its structure and stratum corneum (SC) properties during development compared to adult skin have been reported only for a few races and body sites. The aim of this study was to understand the developmental changes of skin properties in Chinese infants, focusing on SC ceramides and protein secondary structure, which are important for skin barrier function. Three body sites with distinct characteristics (cheeks, inner upper arms, and buttocks) were assessed. Sixty pairs of Chinese infants and their mothers were measured for SC hydration, transepidermal water loss, ceramide levels, sebum with an ester bond, and protein secondary structure of superficial SC. Skin hydration decreased with age at all body sites. TEWL was similar between the 2–12- and 13–24-month-old groups but was higher than the adult group at the buttocks and inner upper arms and was equal to the adult group at the cheeks. These differences coincided with differences in protein secondary structure. Ceramide and sebum levels were lower in the infant groups. We conclude that both the SC functions and the components of infant skin are still developing and are not fully adapted as in adult skin at each body site examined. PMID:29098152

Persistent sciatic artery (PSA) is a rare vascular anomaly present in 0.025% to 0.05% of the population. They are particularly prone to aneurysmal degeneration, potentially leading to distal ischemia, sciatic neuropathy, or rarely rupture. Here, we describe a case of a ruptured PSA aneurysm managed by endovascular embolization. A 70-year-old man initially presented with acute left lower extremity ischemia. He was found to have a popliteal embolus originating from a complete persistent sciatic artery aneurysm. He underwent thrombolysis followed by a femoropopliteal bypass and ligation of the proximal popliteal artery to exclude the PSA. Four weeks later he re-presented with severe pain, a pulsatile buttock mass, and anemia in the setting of hemodynamic instability. A ruptured PSA aneurysm was confirmed by computed tomography angiography (CTA). This was managed emergently by endovascular exclusion of the inflow and outflow vessels using Amplatzer vascular plugs. His postoperative course was complicated by both a foot drop, likely secondary to sciatic nerve ischemia, and a buttock abscess. To our knowledge, this is the first report detailing the endovascular management of a ruptured PSA aneurysm. The etiology, management, and complications associated with the treatment of this rare vascular entity are discussed. Copyright 2010 Annals of Vascular Surgery Inc. Published by Elsevier Inc.

A 40-year-old female presented with a 2-year history of asymptomatic nodules on her lower extremity. Symptoms began with a small dark spot on the right thigh, which progressively enlarged. She then developed similar nodules on her right leg and a lesion on her left buttock. On physical exam, her right proximal lateral thigh revealed a 10 cm x 6 cm indurated, pink-brown, heterogeneous plaque with a hyperpigmented rim. A similar 8 cm x 4 cm indurated plaque was on the distal right thigh. There was also a 3 to 4 cm hyperpigmented, thin plaque on the left posterior lower extremity and on the left inferior lateral buttock. Exam revealed no cervical or supraclavicular lymphadenopathy or organomegaly. Preliminary work-up by her primary physicians included serology for Lyme disease, systemic lupus erythematous, thyroid function tests, blood cultures for mycobacteria, and angiotensin-converting enzyme, which were all negative or within normal limits. Biopsies demonstrated a nodular inflammatory infiltrate within the dermis consisting of histiocytes with local aggregates of plasma cells and lymphocytes. Histiocytes were enlarged with vesicular nuclei. Some plasma cells had prominent Russell bodies, and emperipolesis was observed. Histiocytes stained positively for S-100, CD68 and CD45, while CD1A, CD30, and CD21; microorganism stains were negative.

Observing small changes (SCs) at specific sites is a new form of managing changes in position. We investigated SCs at specific sites considering interface pressure, contact area, body alignment and physical sensation in nine healthy female adults and evaluated SCs using the air mattress that was divided into six cells (A-F). Thirty-three SC combinations at one or several sites were evaluated. Pressure in the sacral region significantly decreased in 28 SC combinations compared with the supine position (p < 0.05), and the effect of pressure redistribution was greater when SCs were applied at several instead of a single site. The contact area at 17 of the 28 SC combinations significantly increased (p < 0.05). Among sites ranked based on interface pressure, body alignment and physical sensation, SCs at sites BCE, AE and BD were the most favorable. The common feature among these three combinations was that they involved tilting the buttock region and one other site. The findings suggested that SCs at the buttock region could reduce disruptions in alignment as well as the impact on physical sensation caused by the body sinking into the mattress and improve interface pressure redistribution via increased contact area with the mattress.

Diminished pelvic arterial flow as a result of intentional coverage/embolization of internal iliac arteries (IIA) during isolated endovascular common iliac artery aneurysm (CIAA) repair or endovascular repair of abdominal aortic aneurysms (EVAR) may result in symptomatic pelvic ischemia. Although generally well tolerated, in severe cases, pelvic ischemia may manifest as recalcitrant buttock claudication, vasculogenic impotence, or perineal, vesicle, rectal, and/or spinal cord ischemia. Branched graft technology has recently become available; however, many patients are not candidates for endovascular repair with these devices. Therefore, techniques to preserve pelvic arterial flow are needed. We reviewed our outcomes of isolated endovascular CIAA repair or EVAR in conjunction with unilateral external-internal iliac artery bypass. Single-center, retrospective review of 10 consecutive patients who underwent hybrid endovascular abdominal aortic aneurysm (AAA) or CIAA repair with concomitant external-internal iliac artery bypass between 2006 and 2015. Demographics, index procedural details, postoperative symptoms, hospital length of stay (LOS), follow-up imaging, and bypass patency were recorded. The cohort of 10 patients was all men with a mean age of 71 years (range: 56-84). Hybrid repair consisted of contralateral IIA coil embolization followed by EVAR with external iliac artery-internal iliac artery (EIA-IIA) bypass. All EIA-IIA bypasses were performed via a standard lower quadrant retroperitoneal approach with a prosthetic bypass graft. Technical success was 100%, and there were no perioperative deaths. One patient developed transient paraplegia, 1 patient had buttock claudication on the side of his hypogastric embolization contralateral to his iliac bypass, and 1 developed postoperative impotence. 20% of patients sustained long-term complications (buttock claudication and postoperative impotence). Mean LOS was 2.8 days (range: 1-9 days). Postoperative imaging was obtained in 90% of patients, and mean follow-up was 10.8 months (range: 0.5-36 months). All bypasses remained patent. Although branched graft technology continues to evolve, strategies to maintain adequate pelvic circulation are necessary to avoid the devastating complications of pelvic ischemia. We have demonstrated that a hybrid approach combining EVAR or isolated endovascular common iliac artery exclusion with a unilateral external-internal iliac bypass via a retroperitoneal approach is well tolerated with a short LOS and excellent patency rates.

Marathon runners seem to have an increased melanoma risk. To identify potential melanoma markers. 150 marathon runners volunteered to take part in the skin cancer screening campaign. After the runners completed a questionnaire about melanoma risk factors, types of sportswear and training programs, they received a total skin examination. The number of lentigines and nevi on the left shoulder and the left buttock were counted in each participant using templates in standardized positions. The potential association of training sportswear and training parameters with the number of lentigines and nevi on the left shoulder was evaluated. The mean number of lentigines on the left shoulder was 19.6 +/- 18.2 (SD), whereas no lentigines were found on the left buttock (p = 0.000). The number of nevi also differed significantly between the 2 localizations with higher numbers on the left shoulder (p = 0.000). While lifetime sunburn history and type of sportswear correlated with the number of lentigines, training parameters had an impact on the number of nevi. Independent of their mean weekly running time, runners with higher heart rates while training, higher training velocities and higher physical strain indexes showed more nevi on the shoulder than the other runners (p = 0.029, 0.046, 0.038, respectively). Sun exposure and high physical strain lead to an increase in melanoma markers such as lentigines and nevi in marathon runners. Copyright 2008 S. Karger AG, Basel.

To determine the feasibility of measuring advanced glycated end-products (AGEs)from skin samples and to evaluate the effects of a combination of vitamins E and C on measures of glycemic control and AGEs in patients with type 2 diabetes mellitus. Twenty-two patients with type 2 diabetes from a Family Medicine clinic were randomly assigned to receive a daily dietary supplement containing either a combination of 400 mg of vitamin E and 500 mg of vitamin C or matching placebo for a period of one year. AGEs were measured from skin samples taken from the buttock. Nineteen subjects completed this one-year pilot study. There were no major problems found in measuring AGEs from skin samples taken from the butttock. Neither the treatment or placebo group had significant changes in glycemic control, protein glycosylation or AGEs. Skin samples taken from the buttock area may be an appropriate site for the determination of AGE levels as this procedure appeared to be well-tolerated. Daily vitamin E and C supplementation did not improve measures of glycemic control or AGE levels in this small sample of patients with type 2 diabetes. Because antioxidant vitamins are inexpensive and free of side effects, additional research using a variety of antioxidant vitamin combinations and dosing regimens is needed.

Worsening pain together with the appearance of a tender mass in his right buttock prompted further imaging, which demonstrated an infiltrative mass engulfing the lumbosacral plexus. This was later shown to be a granulocytic sarcoma on biopsy. Intervertebral disc herniation can be an incidental finding and is not always the cause of sciatica. 2017 BMJ Publishing Group Ltd.

Lupus erythematosus panniculitis or lupus erythematosus profundus is characterized by inflammation of the deep dermis and subcutaneous tissue. It can occur in isolation or associated with chronic systemic or discoid lupus erythematosus. It usually consists of nodules and hardened subcutaneous plaques on the forehead, cheeks, proximal extremities, and buttocks. Periorbital and parotid involvement are rare and can lead to misdiagnosis. We present the case of a patient with lupus erythematosus panniculitis who presented with palpebral edema and involvement of the periocular fat and parotid gland.

Subcutaneous fat necrosis of the newborn (SFNN) developed in a 1-week-old black boy. His mother had received numerous medications for eclampsia. Birth was by Caesarean section and complicated by meconium aspiration. There were numerous nodules over the back, buttocks and extremities that yielded a caseous-like material. Microscopically, these nodules showed crystallization and necrosis of the fat. Hypoglycemia, pneumonia, oliguria, thrombocytopenia, seizures and urinary infection were associated with the cutaneous problem and led to a fatal outcome 2 weeks after birth.

Light skin pigmentation is a known risk factor for skin cancer. Skin color parameters and Fitzpatrick phototypes were evaluated in terms of their usefulness in predicting the risk of skin cancer. A case-control study involved 133 individuals with skin cancer (100 with basal cell carcinoma, 21 with squamous cell carcinoma, 12 with melanoma) and 156 healthy individuals. All of them had skin phototype determined and spectrophotometric skin color measurements were done on the inner surfaces of their arms and on the buttock. Using those data, prediction models were built and subjected to 17-fold stratified cross-validation. A model, based on skin phototypes, was characterized by area under the receiver operating characteristic curve = 0.576 and exhibited a lower predictive power than the models, which were mostly based on spectrophotometric variables describing pigmentation levels. The best predictors of skin cancer were R coordinate of RGB color space (area under the receiver operating characteristic curve 0.687) and melanin index (area under the receiver operating characteristic curve 0.683) for skin on the buttock. A small number of patients were studied. Models were not externally validated. Skin color parameters are more accurate predictors of skin cancer occurrence than skin phototypes. Spectrophotometry is a quick, easy, and affordable method offering relatively good predictive power. Copyright © 2015 American Academy of Dermatology, Inc. Published by Elsevier Inc.

Adatto, Maurice A; Adatto-Neilson, Robyn M; Morren, Grietje

2014-09-01

A growing patient demand for a youthful skin appearance with a favorable body shape has led to the recent development of new noninvasive body contouring techniques. We have previously demonstrated that the combination of bipolar radiofrequency (RF) and optical energies with tissue manipulation is an efficient reshaping modality. Here, we investigated the efficacy and safety of a new high-power version of this combined technology, in terms of adipose tissue reduction and skin tightening. Thirty-five patients received one treatment per week over 6 weeks to their abdomen/flank, buttock, or thigh areas and were followed up to 3 months post completion of the treatment protocol. This new device has an increased power in the bipolar RF, as this parameter appears to be the most important energy modality for volume reduction. Patient circumferences were measured and comparisons of baseline and post treatment outcomes were made. Diagnostic ultrasound (US) measurements were performed in 12 patients to evaluate the reduction in adipose tissue volume, and a cutometer device was used to assess improvements in skin tightening. We observed a gradual decline in patient circumferences from baseline to post six treatments. The overall body shaping effect was accompanied with improvement in skin tightening and was clearly noticeable in the comparison of the before and after treatment clinical photographs. These findings correlated with measurements of adipose tissue volume and skin firmness/elasticity using diagnostic US and cutometer, respectively. The thickness of the fat layer showed on average a 29% reduction between baseline and the 1-month follow up. The average reduction in the circumference of the abdomen/flanks, buttocks, and thighs from baseline to the 3-month follow-up was 1.4, 0.5, and 1.2 cm, respectively, and 93% of study participants demonstrated a 1-60% change in fat layer thickness. Patients subjectively described comfort and satisfaction from treatment, and 97% of them were satisfied with the results at the follow-up visit. The application of high-power RF energy combined with infrared (IR), mechanical massage, and vacuum appears to be an effective modality for the reduction in circumferences of the abdomen/flank, buttock and thigh regions, and the improvement of skin appearance. The present study performed with a new device suggests that the underlying mechanism of action is reduction in the subcutaneous adipose tissue volume and intensification of dermal matrix density.

Liposculpture 4. Fundamentals of good liposculpture technique.

PubMed

Fischer, G

1992-03-01

The fundamentals for good liposculpture are discussed. Horizontal tunneling is to be avoided because the more horizontally the tunnel is angled, the more likely the overlying skin will drape in folds, resulting in poor cosmesis. Superficial tunneling (less than 1 cm) is to be avoided. The author believes that it is important to maintain the adhesive forces and lymphatics of the superficial layer of fat because it leads to more even healing and remodelling postoperatively. Liposuction within 3 cm of the subgluteal fold should be avoided because it can lead to ptosis of the buttocks postoperatively.

Six children with allergic contact dermatitis to methylisothiazolinone in wet wipes (baby wipes).

PubMed

Chang, Mary Wu; Nakrani, Radhika

2014-02-01

Methylchloroisothiazolinone/methylisothiazolinone (MCI/MI) is a combination preservative used in personal care and household products and is a common cause of allergic contact dermatitis (ACD). Recently, MI alone, without MCI, has been increasingly used in consumer products in attempts to minimize allergic reactions. Wet wipes are extensively tested and traditionally believed to be innocuous. MI in wet wipes ("baby wipes") has not been previously reported to cause ACD in children in the United States. Only 1 previous report of ACD in a child in Belgium has been recently reported. We report 6 children with chronic, perianal/buttock, and facial eczematous dermatitis, refractory to multiple topical and oral antibiotics and corticosteroids. All tested positive to MCI/MI on patch testing. None wore diapers. All patients had been using wet wipes containing MI (without MCI) to affected areas. Discontinuation of wipes resulted in rapid and complete resolution. This is the first report of pediatric ACD to MI in wet wipes in the United States, and the largest series to date. ACD to MI in wet wipes is frequently misdiagnosed as eczema, impetigo, or psoriasis. Wet wipes are increasingly marketed in personal care products for all ages, and MI exposure and sensitization will likely increase. Dermatitis of the perianal, buttock, facial, and hand areas with a history of wet wipe use should raise suspicion of ACD to MI and prompt appropriate patch testing. Rapid resolution occurs after the allergen exposure is eliminated. All isothiozolinones should be avoided in personal care and household products for these patients.

Hip osteoarthritis (OA) is the most common diagnosis in primary care adult patients presenting with hip pain but pain location and pain distribution in primary care patients with hip OA have been reported inadequately. To describe pain location and pain distribution in primary care patients with clinical and radiographic confirmed hip OA. Primary care patients with unilateral clinical and radiographic hip OA living on the island of Funen, Denmark were recruited from primary care to participate in a randomized clinical trial. At baseline, patients recorded pain intensity using an 11-box numeric rating scale and the distribution of hip pain using a manikin displaying three separate views: front, back and lateral. Pain drawings were analysed using a template to determine the most frequent pain locations and distribution of pain. Pain drawings were completed by 109 patients of which 108 (99%) were valid. The mean age of patients was 65 (SD 9) years and 44% were females. The mean pain intensity was 5.4 (SD 2.0). A total of 77% had marked the greater trochanter area, 53% the groin area, 42% the anterior/lateral thigh area, 38% the buttock area, 17% the knee and 15% the lower leg area. No patients marked pain exclusively in the areas of the knee, posterior thigh or lower leg. The most common pain locations of patients with hip OA presenting to primary care are the greater trochanter, groin, thigh and buttock areas. No patients recorded pain exclusively in the knee or lower leg. © The Author 2016. Published by Oxford University Press. All rights reserved.

2015-02-01

The sit-to-stand motion (STS) is a frequently executed activity that is affected by weakness in the quadriceps femoris muscle and knee joint pain in patients with knee osteoarthritis (OA). We investigated whether patients with knee OA can efficiently perform STS through mechanical energy transfer assessments. Participants were 20 women with knee OA and 17 age-matched asymptomatic controls. The center of mass (COM), segment angles, joint moments, and powers during STS were measured. The negative mechanical work in the proximal portion of the shank, negative mean powers in the distal portion of the pelvis and proximal portion of the shank, and the positive mean power in the proximal and distal portions of the thigh were significantly lower in the knee OA group than in the control group. Patients with knee OA primarily performed thoracic forward lean movement, shifting their COM closer to the base of support provided by the feet alone, in an attempt to achieve stability at and after buttocks-off. However, control ability, which generates and absorbs kinetic energy quickly, was not enhanced in these patients, and their motion was unable to increase absorption of the mechanical energy in hip extensors and reduce the load on knee extensors. Furthermore, STS in patients with knee OA had reduced energy absorption in the knee extensors from the shank forward lean movement after buttocks-off, had reduced knee extensor efficiency, and made greater use of physiological energy. These findings suggest that, from the standpoint of mechanical energy transfer, patients with knee OA do not perform STS efficiently. Copyright © 2014 Elsevier B.V. All rights reserved.

Leg symptoms associated with sacroiliac joint disorder and related pain.

The symptoms of sacroiliac joint (SIJ) disorders are usually detected in the buttock and groin, and occasionally referred to the thigh and leg. However, lumbar disorders also cause symptoms in these same body regions. The presence of a characteristic, symptomatic pattern in the legs would be useful for diagnosing SIJ disorders. This study aimed to identify specific leg symptoms in patients with SIJ pain originating from the posterior sacroiliac ligament and determine the rate of occurrence of these symptoms. The source population consisted of 365 consecutive patients from February 2005 to December 2007. One hundred patients were diagnosed with SIJ pain by a periarticular SIJ injection (42 males and 58 females, average age 46 years, age range, 18-75 years). A leg symptom map was made by subtracting the symptoms after a periarticular SIJ injection from the initial symptoms, and evaluating the rate of each individual symptom by area. Ninety-four patients reported pain at or around the posterior-superior iliac spine (PSIS). Leg symptoms comprised pain and a numbness/tingling sensation; ≥60% of the patients had these symptoms. Pain was mainly detected in the back, buttock, groin, and thigh areas, while numbness/tingling was mainly detected in the lateral to posterior thigh and back of the calf. Leg symptoms associated with SIJ pain originating from the posterior sacroiliac ligament include both pain and numbness, which do not usually correspond to the dermatome. These leg symptoms in addition to pain around the PSIS may indicate SIJ disorders. Copyright © 2017 Elsevier B.V. All rights reserved.

The sacroiliac joint remains unknown in sub-Saharan Africa. Studies about the sacroiliac diseases are rare Aim : Describe the epidemiological, clinical, radiological and etiological characteristics of sacroiliac joint diseases in Abidjan Methods : Retrospective and descriptive study concerning 17 patients hospitalized from February 2003 to April 2010 in the department of rheumatology of university hospital center of Cocody (Abidjan) for buttock pain or others functional signs evoking sacroiliac joint which were attested by radiographic lesions. We were interested on the epidemiological, clinical and radiological characteristics and the etiologies in the sacroiliac disease. The hospital prevalence of sacroiliac diseases was 0.55% corresponding in 17 of 3067 rheumatological diseases. The female sex predominated (82.35%) and the mean age of 25.58 years. Gyneco-obstetric events were the predominant risk factors (47.05%). Sacroiliac damage was manifested by inflammatory pain (64.7%) localized at the buttock or lumbar spine, radiating to the thigh (52.9%) and was accompanied by functional disability (82.2%) and fever was not present every time (64.7%). The physical findings were the tripod sign positive (58.8%), the monopodal backing positive (41.2%) and palpation painful of sacroiliac joint. The standard radiograph revealed a blurring aspect and widening of joint space associated with demineralization (68.4%), a joint space narrowing and erosion of articular banks (23.5%). The etiologies found were bacterial arthritis (82.3%) mainly pyogenic (70.58%), osteoarthritis (11.7%) and ankylosing spondylitis (5.9%). Sacroiliac joint diseases are rare in rheumatology practice in Abidjan, concern younger subjects and are dominated by pyogenic sacroiliitis.

Pressure ulcers are a common problem, especially in older patients. In Japan, most institutionalized older people are malnourished and show extreme bony prominence (EBP). EBP is a significant factor in the development of pressure ulcers due to increased interface pressure concentrated at the skin surface over the EBP. The use of support surfaces is recommended for the prophylaxis of pressure ulcers. However, the present equivocal criteria for evaluating the pressure redistribution of support surfaces are inadequate. Since pressure redistribution is influenced by physique and posture, evaluations using human subjects are limited. For this reason, models that can substitute for humans are necessary. We developed a new EBP model based on the anthropometric measurements, including pelvic inclination, of 100 bedridden elderly people. A comparison between the pressure distribution charts of our model and bedridden elderly subjects demonstrated that maximum contact pressure values, buttock contact pressure values, and bone prominence rates corresponded closely. This indicates that the model provides a good approximation of the features of elderly people with EBP. We subsequently examined the validity of the model through quantitative assessment of pressure redistribution functions consisting of immersion, envelopment, and contact area change. The model was able to detect differences in the hardness of urethane foam, differences in the internal pressure of an air mattress, and sequential changes during the pressure switching mode. These results demonstrate the validity of our new buttock model in evaluating pressure redistribution for a variety of surfaces. Copyright © 2010 Tissue Viability Society. Published by Elsevier Ltd.

Tank tests of a family of flying-boat hulls

Shoemaker, James M; Parkinson, John B

1934-01-01

This report presents towing tests made in the N.A.C.A. tank of a parent form and five variations of a flying-boat hull. The beams of two of the derived forms were made the same as that of the parent and the lengths changed by increasing and decreasing the spacing of stations. The lengths of the two others of the derived forms were made the same as that of the parent while the beams were changed by increasing and decreasing the spacing of buttocks, all other widths being changed in proportion. The remaining derived form has the same length and beam as the parent, but the lines of the forebody were altered to give a planing bottom with no longitudinal curvature forward of the step. The test data were analyzed to determine the minimum resistance and the angle at which it occurs for all speeds and loads. The results of this analysis are given in the form of non dimensional curves for each model. The effect of variation in over-all size, as indicated by a "complete" test on any given hull, is pointed out. The effect of changing length alone by the spacing of buttocks, as well as the effects of the changes in length-beam ratio and longitudinal curvature that result from these operations are discussed. The difficulties encountered in interpreting test results of systematic families derived by the method used are emphasized. Further studies are suggested in which changes in the variable under consideration would not be obscured by secondary changes in other important variables.

Scientific evidence regarding microclimate and its effects on the risk of pressure ulcers (PU) remains sparse. It is known that elevated skin temperatures and moisture may affect metabolic demand as well as the mechanical behaviour of the tissue. In this study, we incorporated these microclimate factors into a novel, 3-dimensional multi-physics coupled model of the human buttocks, which simultaneously determines the biothermal and biomechanical behaviours of the buttocks in supine lying on different support surfaces. We compared 3 simulated thermally controlled mattresses with 2 reference foam mattresses. A tissue damage score was numerically calculated in a relevant volume of the model, and the cooling effect of each 1°C decrease of tissue temperature was deduced. Damage scores of tissues were substantially lower for the non-foam mattresses compared with the foams. The percentage tissue volume at risk within the volume of interest was found to grow exponentially as the average tissue temperature increased. The resultant average sacral skin temperature was concluded to be a good predictor for an increased risk of PU/injuries. Each 1°C increase contributes approximately 14 times as much to the risk with respect to an increase of 1 mmHg of pressure. These findings highlight the advantages of using thermally controlled support surfaces as well as the need to further assess the potential damage that may be caused by uncontrolled microclimate conditions on inadequate support surfaces in at-risk patients. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Synthetic meshes have been used extensively to augment surgical management of pelvic organ prolapses. Posterior intravaginal sling (IVS) is a technique used for correcting vaginal vault/apical prolapse, posterior vaginal prolapse or rectocele. There are limited data on long-term safety of this procedure. In a subanalysis of the IVS tapes from the SUSPEND trial performed secondary to the large number of patients with complications of suburethral sling erosions after IVS, it was noted that the sling erosion tended to have a delayed presentation secondary to poor incorporation of the mesh. A 48-year-old woman with cystocele, uterine prolapse and rectocele had undergone total vaginal hysterectomy, mesh-augmented anterior repair, posterior colporrhaphy and posterior intravaginal slingplasty (IVS) in July 2005. Thirty months after the surgery, she presented with gradual symptoms of copious vaginal discharge for several weeks followed by constant right buttock pain and swelling. Examination was notable for intact mesh with no signs of erosion and a 3-cm induration deep within the right buttock. Computed tomography suggested a pelvic abscess. Magnetic resonance imaging confirmed a right ischiorectal fossa abscess and a vaginal fistula. The patient underwent sling excision, right ischiorectal fossa exploration and vaginal fistula repair. A fistulous tract was found to extend along the intact sling from the vaginal epithelium toward the right ischiorectal fossa. At 2 months' followup, there were no recurrences or other complications. This is the first report of a delayed complication of an ischiorectal abscess associated with an ischiorectal-vaginal fistula that presented 30 months after the placement of a posterior IVS.

Neurocutaneous melanocytosis is a rare congenital dysplasia of the neuroectodermal melanocyte precursor cells that leads to proliferation of melanin-producing cells in the skin and leptomeninges. We describe a newborn with a giant congenital melanocytic nevus on his back, buttocks, and thighs. His brain magnetic resonance imaging study revealed bilateral T1 hyperintense lesions in the cerebellum and in the amygdala, hydrocephalus, and a Blake's pouch cyst, consistent with neurocutaneous melanocytosis and Dandy-Walker malformation. Neurocutaneous melanocytosis has a wide clinical spectrum that includes hydrocephalus, epilepsy, cranial nerve palsy, increased intracranial pressure, and sensorimotor deficits. Copyright © 2014.

The GORE EXCLUDER Iliac Branch Endoprosthesis (IBE; W. L. Gore and Associates, Flagstaff, Ariz) is an iliac branch stent graft system designed to preserve internal iliac artery perfusion during endovascular repair of aortoiliac aneurysms (AIAs) and common iliac artery (CIA) aneurysms (CIAAs). We report the 6-month primary end point results of the IBE 12-04 United States pivotal trial for endovascular treatment of AIAs and CIAAs using the IBE device. The trial prospectively enrolled 63 patients with AIA or CIAA who underwent implantation of the IBE device at 28 centers in the United States from 2013 to 2015. All patients underwent placement of a single IBE device. Twenty-two patients (34.9%) with bilateral CIAs were enrolled after undergoing staged coil or plug embolization (21 of 22) or surgical revascularization (1 of 22) of the contralateral internal iliac artery. Follow-up at 30 days and 6 months included clinical assessment and computed tomography angiography evaluation as assessed by an independent core laboratory. The primary effectiveness end point was freedom from IBE limb occlusion and reintervention for type I or III endoleak and ≥60% stenosis at 6 months, and the secondary effectiveness end point was freedom from new onset of buttock claudication on the IBE side at 6 months. Mean CIA diameter on the IBE side was 41.0 ± 11.4 mm (range, 25.2-76.3 mm). There were no procedural deaths, and technical success, defined as successful deployment and patency of all IBE components and freedom from type I or III endoleak, was 95.2% (60 of 63). Data for 61 patients were available for primary and secondary effectiveness end point analysis. Internal iliac limb patency was 95.1% (58 of 61), and no new type I or III endoleaks or device migrations were observed at 6 months. The three patients with loss of internal iliac limb patency were asymptomatic, and freedom from new-onset buttock claudication on the IBE side was 100% at 6 months. New-onset buttock claudication occurred on the non-IBE treatment side in six of 21 patients (28.6%) who underwent staged internal iliac artery coil embolization. These results confirm that the IBE device is effective at treating CIAAs and AIAs, maintaining blood flow into the internal iliac artery, and avoiding complications associated with internal iliac artery sacrifice. Follow-up will be continued for 5 years to establish the long-term durability of iliac aneurysm repair with the IBE device. Copyright © 2017 Society for Vascular Surgery. Published by Elsevier Inc.

Exposure of the sciatic nerve in the gluteal region without sectioning the gluteus maximus: Analysis of a series of 18 cases

PubMed Central

Socolovsky, Mariano; Masi, Gilda Di

2012-01-01

Background: Dissecting through the gluteus maximus muscle by splitting its fibers, instead of complete sectioning of the muscle, is faster, involves less damage to tissues, and diminishes recovery time. The objective of the current paper is to present a clinical series of sciatic nerve lesions where the nerve was sufficiently exposed via the transgluteal approach. Methods: We retrospectively selected 18 traumatic sciatic nerve lesions within the buttock, operated upon from January 2005 to December 2009, with a minimum follow-up of 2 years. In all patients, a transgluteal approach was employed to explore and reconstruct the nerve. Results: Ten males and eight females, with a mean age of 39.7 years, were studied. The etiology of the nerve lesion was previous hip surgery (n = 7), stab wound (n = 4), gunshot wound (n = 3), injection (n = 3), and hip dislocation (n = 1). In 15 (83.3%) cases, a motor deficit was present; in 12 (66.6%) cases neuropathic pain and in 12 (66.6%) cases sensory alterations were present. In all cases, the transgluteal approach was adequate to expose the injury and treat it by neurolysis alone (10 cases), neurolysis and neurorrhaphy (4 cases), and reconstruction with grafts (4 cases; three of these paired with neurolysis). The mean pre- and postoperative grades for the tibial nerve (LSUHSC scale) were 1.6 and 3.6, respectively; meanwhile, for the peroneal division, preoperative grade was 1.2 and postoperative grade was 2.4. Conclusions: The transgluteal approach adequately exposes sciatic nerve injuries of traumatic origin in the buttock and allows for adequate nerve reconstruction without sectioning the gluteus maximus muscle.

Sciatic nerve injury from intramuscular injection: a persistent and global problem.

PubMed

Mishra, P; Stringer, M D

2010-10-01

An intramuscular (i.m.) injection into the buttock risks damaging the sciatic nerve. Safe injection practices need to be understood by doctors and nurses alike. The aims of this study were to determine if sciatic nerve injury because of i.m. injection is a continuing problem and to establish the availability of published guidelines on i.m. injection techniques. Intramuscular injection related sciatic nerve injury claims to the New Zealand Accident Compensation Corporation between July 2005 and September 2008 were reviewed. Nursing organisations were surveyed to enquire about guidelines on i.m. injection. I.m. injection related sciatic nerve injuries in the medical and medicolegal literature (1989-2009) were systematically reviewed. There were eight claims for sciatic nerve injection injury made to the ACC during the 3-year study period; all were in young adults. Only one of the nursing organisations contacted had published guidelines on i.m. injection technique, and these related specifically to immunisation. Seventeen reports of patients with sciatic nerve injury from i.m. injection were identified comprising a total of 1506 patients, at least 80% of which were children. Nine court decisions finding in favour of the plaintiff were identified, all from the North American legal system. A broad range of drugs were implicated in the offending i.m. injections. Sciatic nerve injury from an i.m. injection in the upper outer quadrant of the buttock is an avoidable but persistent global problem, affecting patients in both wealthy and poorer healthcare systems. The consequences of this injury are potentially devastating. Safer alternative sites for i.m. injection exist. These should be promoted more widely by medical and nursing organisations. © 2010 Blackwell Publishing Ltd.

This study was designed to investigate the status of skin injuries in older individuals caused by adhesive tape and the associated factors for skin injury. Older individuals are susceptible to skin injuries caused by medical adhesive tape. However, the current status of such skin injuries and the associated factors involved has not been clearly elucidated. Prospective cohort design, using comparative and descriptive statistical tests. The subjects were 155 patients aged 65 or older who were admitted to a long-term care facility and required the use of medical adhesive tape. Patients who showed no skin injuries were selected and the incidence rate and status of skin injuries that occurred during the eight-week study period were investigated. The skin injuries observed were classified by a dermatologist. The associated factors were examined statistically. Informed consent was obtained from all patients. Skin injuries developed at 34 sites in 24 subjects. The cumulative incidence rate was 15.5%, and the incidence density was 38.0/1000 person-days. Many of the skin injuries occurred around pressure ulcers and intravenous hyperalimentation sites. Other prevalent areas included the buttocks and back, where tape is commonly used. The skin injuries were classified as contact dermatitis (70.6%), trauma (20.6%) and infection (8.8%). The ratio of skin contamination and skin mobility in patients with contact dermatitis was significantly higher than in patients without skin injury. The highest incidence rate was observed in the buttock area of patients with pressure ulcers. The incidence rate of contact dermatitis was the highest. Skin care to minimise contamination and more effective ways of applying medical adhesive tape may be needed to prevent contact dermatitis.

Concordant paresthesia coverage is an independent predictor of pain relief following spinal cord stimulation (SCS). Using aggregate data, our objective is to produce a map of paresthesia coverage as a function of electrode location in SCS. This retrospective analysis used x-rays, SCS programming data, and paresthesia coverage maps from the EMPOWER registry of SCS implants for chronic neuropathic pain. Spinal level of dorsal column stimulation was determined by x-ray adjudication and active cathodes in patient programs. Likelihood of paresthesia coverage was determined as a function of stimulating electrode location. Segments of paresthesia coverage were grouped anatomically. Fisher's exact test was used to identify significant differences in likelihood of paresthesia coverage as a function of spinal stimulation level. In the 178 patients analyzed, the most prevalent areas of paresthesia coverage were buttocks, anterior and posterior thigh (each 98%), and low back (94%). Unwanted paresthesia at the ribs occurred in 8% of patients. There were significant differences in the likelihood of achieving paresthesia, with higher thoracic levels (T5, T6, and T7) more likely to achieve low back coverage but also more likely to introduce paresthesia felt at the ribs. Higher levels in the thoracic spine were associated with greater coverage of the buttocks, back, and thigh, and with lesser coverage of the leg and foot. This paresthesia atlas uses real-world, aggregate data to determine likelihood of paresthesia coverage as a function of stimulating electrode location. It represents an application of "big data" techniques, and a step toward achieving personalized SCS therapy tailored to the individual's chronic pain. © 2017 International Neuromodulation Society.

This study was carried out with the objective to obtain the anthropometric data of primary school children from Year 1 to Year 6 and evaluate the children's anthropometry with the current dimensions of classroom furniture (i.e. chair and table). In addition, this study also proposed the design dimensions for the improvement in classroom furniture design with the consideration of children's anthropometric data. A total of 390 children selected from 13 primary schools in Perlis, Malaysia were participated in this study. There were 11 anthropometric measurements of children have been measured in this study, which include stature (St), popliteal height (PH), knee height (KH), thigh thickness (TT), buttock popliteal length (BPL), hip breadth (HB), sitting shoulder height (SSH), sitting elbow height (SEH), forearm-hand length (FHL), height of lumbar point (HLP) and buttock clearance (BC). Besides that, 7 dimensions relating to current classroom chair have been measured, such as seat height (SH), seat depth (SD), seat width (SW), upper edge of backrest (UEB), lower edge of backrest (LEB), S point (SP), overall chair height (OCH). Another 5 dimensions of the existing classroom table have been measured too, which involve table height (TH), table depth (TD), table width (TW), under table height (UH) and seat to table clearance (STC). All the measurements were performed by using metal measuring tape. The anthropometric data of the children were analyzed with the help of Microsoft Excel 2013. Several equations with associated with the anthropometric data and furniture dimensions have been applied in this research. The new design dimensions for classroom furniture that proposed in this paper which based on the collected anthropometric data can be referred as a guideline for classroom furniture design. The implementation of these data may help to create comfortability, safety, suitability and improve performance of children in the classroom.

To investigate the effectiveness and interactions of 2 methods of pressure ulcer prevention, wheelchair cushions and pressure relief maneuvers, on interface pressure (IP) and blood flow of the buttocks. Within-subject repeated measures. Rehabilitation center. Wheelchair users with a spinal cord injury or disorder (N=17). Participants performed 3 forward leans and 2 sideward leans with different degrees of lean while seated on each of 3 different wheelchair cushions. IP measured with a custom sensor and blood flow measured with laser Doppler flowmetry were collected at the ischial tuberosity. Pressure relief maneuvers had a significant main effect on the ischial IP (P<.001); all maneuvers except for the small frontward lean resulted in a significant reduction in IP compared with upright sitting. Blood flow significantly varied across postures (P<.001) with flow during upright sitting and small forward leans being significantly lower than during the full and intermediate leans in both the forward and sideward directions. The results of the study highlight the importance of positioning wheelchair users in a manner that facilitates in-seat movement. Regardless of the cushion being used, the pressure relief maneuvers resulted in very large reductions in IPs and significant increases in buttock blood flow. Only the small frontward lean was shown to be ineffective in reducing pressure or increasing blood flow. Because these pressure relief maneuvers involved postural changes that can occur during functional activities, these pressure relief maneuvers can become a part of volitional pressure relief and functional weight shifts. Therefore, clinical instruction should cover both as a means to impart sitting behaviors that may lead to better tissue health. Copyright © 2014 American Congress of Rehabilitation Medicine.

Hand, foot and mouth disease (HFMD) is classically defined as a childhood fever accompanied by a rash with vesicles or erosions of the oral mucosa, hands, feet and sometimes the buttocks. Severe neurological complications are associated with enterovirus 71 outbreaks in Asia. Recently, it has been suggested that HFMD is related to coxsackie virus A6 (CV-A6) when there is an atypical rash. The objective of the study is to determine the dermatological pattern of HFMD and to identify the virus serotypes associated with a specific dermatological pattern. A prospective, cross-sectional study was conducted in 7 pediatric dermatology units in France from March 2010 to February 2012. All children with clinically suspected diagnosis of HFMD were included. Clinical data were collected and swabs from the nasopharynx and vesicles were taken for reverse transcription polymerase chain reaction and genotyping. Only children with confirmed HFMD--defined by clinical diagnosis of HFMD and positive enterovirus polymerase chain reaction results--were included for analysis. One hundred and four children consulted for suspected HFMD, including 89 (mean age: 25.7 months; sex ratio M/F 1.54) with confirmed HFMD. Seventy-eight (87.6%) had skin lesions on sites other than hand, feet and mouth. Thirty-seven (41.5%) had 5 or more anatomical sites involved (hand, feet and mouth, buttocks, legs, arms and trunk) considered as widespread exanthema. Widespread vesicular exanthema was observed with both CV-A6 and CV-A16. Peri-oral rash was associated with CV-A6 (P < 0.001). HFMD has a clinical spectrum ranging from classical to generalized vesicular exanthema. Generalized and atypical exanthema were observed with both CV-A6 and CV-A16 infections. CV-A6 is associated with peri-oral rash.

Background Prolonged sitting leads to low back discomfort and lumbopelvic muscle fatigue. This study examined the characteristics of body perceived discomfort and trunk muscle fatigue during 1 hour of sitting in three postures in office workers. Methods Thirty workers sat for 1 hour in one of three sitting postures (i.e., upright, slumped, and forward leaning postures). Body discomfort was assessed using the Body Perceived Discomfort scale at the beginning and after 1 hour of sitting. Electromyographic (EMG) signals were recorded from superficial lumbar multifidus, iliocostalis lumborum pars thoracis, internal oblique (IO)/transversus abdominis (TrA), and rectus abdominis muscles during 1 hour of sitting. The median frequency (MDF) of the EMG power spectrum was calculated. Results Regardless of the sitting posture, the Body Perceived Discomfort scores in the neck, shoulder, upper back, low back, and buttock significantly increased after 1 hour of sitting compared with baseline values (t(9) = −11.97 to −2.69, p < 0.05). The MDF value of the EMG signal of rectus abdominis, iliocostalis lumborum pars thoracis, and multifidus muscles was unchanged over time in all three sitting postures. Only the right and left IO/TrA in the slumped sitting posture was significantly associated with decreased MDF over time (p = 0.019 to 0.041). Conclusion Prolonged sitting led to increased body discomfort in the neck, shoulder, upper back, low back, and buttock. No sign of trunk muscle fatigue was detected over 1 hour of sitting in the upright and forward leaning postures. Prolonged slumped sitting may relate to IO/TrA muscle fatigue, which may compromise the stability of the spine, making it susceptible to injury. PMID:27014491

To study the clinical presentation of femoral head osteonecrosis (ONFH). Publications dedicated to this aspect of ONFH are rare. Our aim was to systematically collect and describe the clinical data. A prospective survey was conducted in a cohort of ONFH recruited from a dedicated clinic for osteonecrosis. The history of symptoms, medical management, and physical findings were obtained from 88 patients suffering from 125 ONFH. Subgroups were formed: bilateral versus unilateral ONFH, radiological stages 1-2 (pre-fractured) versus fractured stage 3 versus stage 4. ONFH was bilateral in 63 %, especially in corticosteroid users and in sickle-cell cases. These patients were younger but had similar BMIs compared to the unilateral cases. The pain was mechanical in 79 % of hips and inflammatory in 21 %. Acute pain at the onset was present in 55 % of hips. The localization of this pain was variable, including in the groin, the buttocks, or diffused in the lower limbs. A limp was present in 50 % of the patients, only when one hip was painful. The physical examination of the hip was normal in 31 %, especially in stages 1-2 (55 %). The diagnosis delay was 12 months, with inadequate medical management in 51 % of patients. In ONFH cases, no typical clinical pattern was found. The clinical presentation was very variable, sometimes having spine or knee symptoms with a normal physical examination of the hip. ONFH should be systematically suspected in cases of onset of pain in the pelvis, buttocks, groin, and lower limbs.

Background/Objective: To study the effect on tissue perfusion of relieving interface pressure using standard wheelchair pushups compared with a mechanical automated dynamic pressure relief system. Design: Repeated measures in 2 protocols on 3 groups of subjects. Participants: Twenty individuals with motor-complete paraplegia below T4, 20 with motor-complete tetraplegia, and 20 able-bodied subjects. Methods: Two 1-hour sitting protocols: dynamic protocol, sitting configuration alternated every 10 minutes between a normal sitting configuration and an off-loading configuration; wheelchair pushup protocol, normal sitting configuration with standard wheelchair pushup once every 20 minutes. Main Outcome Measures: Transcutaneous partial pressures of oxygen and carbon dioxide measured from buttock overlying the ischial tuberosity and interface pressure measured at the seat back and buttocks. Perfusion deterioration and recovery times were calculated during changes in interface pressures. Results: In the off-loading configuration, concentrated interface pressure during the normal sitting configuration was significantly diminished, and tissue perfusion was significantly improved. Wheelchair pushups showed complete relief of interface pressure but incomplete recovery of tissue perfusion. Conclusions: Interface pressure analysis does not provide complete information about the effectiveness of pressure relief maneuvers. Measures of tissue perfusion may help establish more effective strategies. Relief achieved by standard wheelchair pushups may not be sufficient to recover tissue perfusion compromised during sitting; alternate maneuvers may be necessary. The dynamic seating system provided effective pressure relief with sustained reduction in interface pressure adequate for complete recovery of tissue perfusion. Differences in perfusion recovery times between subjects with spinal cord injury (SCI) and controls raise questions about the importance of changes in vascular responses to pressure after SCI.

Effective stone disintegration by extracorporeal shockwave lithotripsy (ESWL) may depend on patient- and stone-related factors. We investigated predictors of disintegration failure in ESWL for a solitary ureteral calculus. From July 2008 to May 2010, 203 patients who underwent ESWL for a solitary ureteral calculus were enrolled. Clinical and radiologic data were collected, and factors related to ESWL failure were analyzed. Fifty-two patients (25.6%) showed ESWL failure, with a mean follow-up of 41 days. Forty patients (19.7%) required retreatment, including 12 who underwent repeat ESWL and 28 who underwent curative ureteroscopy. Patients with ESWL failure had significantly higher body weight, body mass index (BMI), and buttock circumference (BC) than patients for whom ESWL was successful. Univariate analysis showed that stone burden (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.03-1.06) and BC (OR, 1.06; 95% CI, 1.01-1.11) were predictors of ESWL failure, while BMI was a potential predictor with borderline significance (OR, 1.09; 95% CI, 0.99-1.20). Multivariate analysis showed that stone burden (OR, 1.04; 95% CI, 1.03-1.06) was a significant predictor for all patients. On stratifying patients according to the level of ureteral calculi, BC was found to be an independent predictor (OR, 1.35; 95% CI, 1.02-1.80) for ESWL failure for middle/lower ureteral calculi and BMI (OR, 1.47; 95% CI, 1.13-1.91) for upper ureteral calculi. Stone burden is the main predictor of ESWL failure for all patients with ureteral calculi. BC and BMI are independent predictors for ESWL failure for middle/lower and upper ureteral calculi, respectively. Copyright © 2012. Published by Elsevier B.V.

Pediatric burns due to abuse are unfortunately relatively common, accounting for 5.8-8.8% of all cases of abuse annually. Our goal was to evaluate our 36-year experience in the evaluation and management of the victims of abuse in the North Texas area. A prospectively maintained database containing records on all admissions from 1974 through 2010 was queried for all patients aged less than 18 years. Patients admitted for management of a non-burn injury were excluded from the analysis. Of 5,553 pediatric burn admissions, 297 (5.3%) were due to abuse. Children with non-accidental injuries tended to be younger (2.1 vs. 5.0 years, p<0.0001) and male (66.0 vs. 56.5%, p=0.0008). Scald was the most common mechanism of injury overall (44.8%), and was also the predominant cause of inflicted burns (89.6 vs. 42.3%, p<0.0001). Multivariate logistic regression identified age, gender, presence of a scald, contact, or chemical burn, and injury to the hands, bilateral feet, buttocks, back, and perineum to be significant predictors of abuse. Victims of abuse were also found to have worse outcomes, including mortality (5.4 vs. 2.3%, p=0.0005). After adjusting for age, mechanism of injury, and burn size, abuse remained a significant predictor of mortality (OR 3.3, 95% CI 1.5-7.2) CONCLUSIONS: Clinicians should approach all burn injuries in young children with a high index of suspicion, but in particular those with scalds, or injuries to the buttocks, perineum, or bilateral feet should provoke suspicion. Burns due to abuse are associated with worse outcomes, including length of stay and mortality. Copyright © 2016. Published by Elsevier Ltd.

The primary objective of this study was to identify skin disorders encountered in a population of sport sailors. Unlike merchant mariners and fishermen, there is sparse literature on this maritime population. Secondary objectives were to uncover on-board conditions that may contribute to dermatological problems in this population. We conducted a prospective study during the 2012 AG2R transatlantic race. Sixteen two-man crews participated in this race, all using the same model of sailboat (Bénéteau Figaro 2). Clinical examinations were conducted, photographs taken, and questionnaires containing 34 questions were handed out before departure and on arrival, 22 to 24 days later. Twenty-eight of 32 skippers (88%) participated in departure data collection, and 18 (56%) completed data collection on arrival. The average age of sailors was 34 years (SD = 8). Compared with skin diseases documented on departure, there was an increased amount of folliculitis on the buttocks, fungal infections, and hyperkeratosis of the hands on arrival. Furthermore, several new skin problems were found postrace: skin scaling, skin erosions on the buttocks, dyshidrosis, thermal burns, and sunburns. The use of protective gear and sunscreen was common, but on-board hygiene was poor with infrequent bathing and clothing changes. Skin conditions are nearly universal in this maritime population. Further assessments are needed to know if long-term use of protective gear; improved hygiene; use of barrier creams; and proper on-board care of fungal infections, wounds, and burns could reduce the number and severity of skin problems encountered in sport sailors.

Correlation between Lumbar Lordosis Angle and Degree of Gynoid Lipodystrophy (Cellulite) in Asymptomatic Women

PubMed Central

Milani, Giovana Barbosa; Filho, A’Dayr Natal; João, Sílvia Maria Amado

2008-01-01

INTRODUCTION Gynoid lipodystrophy (cellulite) has been cited as a common dermatological alteration. It occurs mainly in adult women and tends to gather around the thighs and buttocks. Its presence and severity have been related to many factors, including biotype, age, sex, circulatory changes, and, as some authors have suggested, mechanical alterations such as lumbar hyperlordosis. OBJECTIVE To correlate the degree of cellulite with the angle of lumbar lordosis in asymptomatic women. METHODS Fifty volunteers were evaluated by digital photos, palpation, and thermograph. The degree of cellulite was classified on a scale of 1–4. Analyses were performed on the superior, inferior, right and left buttocks (SRB, IRB, SLB, ILB), and the superior right and left thighs (SRT, SLT). The volunteers underwent a lateral-view X-ray, and the angle of lumbar lordosis was measured using Cobb’s method (inferior endplate of T12 and the superior endplate of S). The data were statistically analyzed using ANOVA and Spearman’s correlation. A significance level of 5% was adopted. RESULTS Volunteers had a mean age of 26.1 ± 4.4 years and a mean body mass index of 20.7 ± 1.9 kg/m2. There was no significant difference in lumbar lordosis angle between those with cellulite classes 2 and 3 (p ≥ 0.297). There was also no correlation between lumbar lordosis angle and the degree of cellulite (p ≥ 0.085 and r ≥ 0.246). CONCLUSIONS The analysis suggests that there is no correlation between the degree of cellulite and the angle of lumbar lordosis as measured using Cobb’s method. PMID:18719762

Antiphospholipid antibody syndrome complicated by Grave's disease.

The report describes a woman with primary antiphospholipid antibody syndrome complicated with Grave's disease. Developing symptoms included a small cutaneous nodule on her finger and subsequently ecchymotic purpura on the cheeks, ears, buttocks and lower legs. Histological examinations showed thrombosed vessels in the dermis without or with hemorrhage, respectively. Laboratory investigation revealed positive lupus anticoagulant and immunogenic hyperthyroidism due to Grave's disease. There is a close relationship between the cutaneous manifestation of antiphospholipid antibody syndrome and the activities of Grave's disease and a possible link of antiphospholipid antibody syndrome with Grave's disease was suggested both by the etiology of the disease as well as the disease activity.

Attack of the scabies: what to do when an outbreak occurs.

PubMed

Haag, M L; Brozena, S J; Fenske, N A

1993-10-01

Scabies remains a significant source of morbidity in nursing home residents because of its highly contagious nature. It is characterized by severe pruritus and papules, pustules, burrows, nodules, and occasionally urticarial lesions. Lesions are commonly found on the wrists, finger webs, antecubital fossae, axillae, areolae, periumbilical region, lower abdomen, genitals, and buttocks. Diagnosis is based on the history, physical examination, and demonstration of mites, eggs, or scybala on microscopic examination. Several topical scabicides are available, but permethrin cream appears to be less toxic and more effective in cases that are resistant to other agents. Successful management requires evaluation of individuals with close patient contact.

Lichen planus is an uncommon disease in children, and only 2 to 3% of affected patients are under twenty years of age. This dermatosis may appear in several clinical forms, which vary according to the morphology and distribution of lesions. In less than 0.2% of all lichen planus cases, the lesions are distributed along the lines of Blaschko, and is a variant called linear lichen planus. This is a case report of a patient aged two years and eight months, who presented keratotic violaceous papules, affecting the abdomen, buttocks and right thigh, distributed along the lines of Blaschko. Histopathological examination confirmed a diagnosis of linear lichen planus. PMID:24346902

Herpes zoster is a common dermatological condition which affects up to 20% of the population, most frequently involving the thoracic and facial dermatomes with sacral lesions occurring rarely and only a few reported cases of penile shingles. We report two cases of unusual penile clinical presentations of varicella zoster virus infection in immunocompetent men. The patients presented with grouped clusters of vesicles and erythema on the left side of penile shaft and posterior aspect of the left thigh and buttock, involving s2-s4 dermatomes. The lesions resolved quickly upon administration of oral antiviral therapy. Penile herpes zoster should not be overlooked in patients with unilateral vesicular rash.

Recently in Mexico the number of cosmetic surgeries has increased. These procedures are often carried out by unqualified people using obsolete and contraindicated products such as injectable oil, which cause uncorrectable disfigurement or more serious complications, even death, after reaching the systemic circulation. We report the case of a fat embolism syndrome (FES) caused by injections of vitamin E (tocopherol) in order to increase the volume of the buttocks. This case of a FES caused by injections of vitamin E was confirmed by gas chromatography coupled to mass spectrometry. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

2014-02-20

A 21-year-old man presented with a widespread, intensely pruritic skin rash, which developed acutely 5 days after returning from a backpacking holiday in Thailand. On initial presentation to his general practitioner, an erythematous, papular rash was noted in the upper right back, with smaller clusters of lesions on the buttocks and right arm. Based on the anatomical distribution of the lesions, a preliminary diagnosis of shingles was made. Over the following 2 weeks, the lesions failed to improve, and new snake-like lesions appeared. A dermatologist made the diagnosis of cutaneous larva migrans. The skin lesions rapidly resolved following oral albendazole therapy.

2017-01-01

As the use of compressed air in industrial work has increased, so has the risk of associated pneumatic injury from its improper use. However, damage of large intestine caused by compressed air is uncommon. Herein a case of pneumatic rupture of the rectum is described. The patient was admitted to the Emergency Room complaining of abdominal pain and distension. His colleague triggered a compressed air nozzle over his buttock. On arrival, vital signs were stable but physical examination revealed peritoneal irritation and marked distension of the abdomen. Computed tomography showed a large volume of air in the peritoneal cavity and subcutaneous emphysema at the perineum. A rectal perforation was found at laparotomy and the Hartmann procedure was performed. PMID:28706893

We report on the case of an established perinuclear antineutrophil cytoplasmic antibody (pANCA) associated renal vasculitis being treated with prednisolone and rituximab, where the patient presented with leg weakness, urinary and faecal incontinence and buttock pain consistent with transverse myelitis. The patient underwent MRI scanning showing patchy cord enhancement from T10 to the conus, which was suggestive of a cord malignancy. Prior to a cord biopsy, he was treated with steroids and a repeat MRI showed resolution of the original lesion with a new similar lesion from C7 to T3. He made a marked recovery after further treatment with high dose steroids and plasma exchange.

Introduction: The ischiogluteal bursa is an inconstant anatomical finding located between the ischial tuberosity and the gluteus maximus. Ischiogluteal bursitis is a rare disorder. Case Report: We report the case of a 43-year-old female patient with bilateral calcifying ischiogluteal bursitis. The patient had no relevant medical history of systemic illness or major trauma to the buttock. After aspiration of both ischiogluteal bursitis which delievered calcareous deposits and instillation of a mixture of 1cc betamethasone (6 mg) and 4 cc of 1% lidocaine the patient was out of any complaints. Conclusion: Calcifying ischiogluteal bursitis is a rare entity but easily diagnosed on radiographs. Aspiration and local steroid instillation give good relief from symptoms. PMID:27298836

Unusual clinical presentation of sporotrichosis in three members of one family.

Sporotrichosis is a mycosis caused by the dimorphic fungus Sporothrix spp., and the primary mode of transmission is traumatic inoculation of fungus conidia from plants and other organic matter. Sporotrichosis was established in a cat and in three members of one family from a rural area, by fungal growth in culture. The cutaneous lesions developed on the lower buttock and limbs with no report of any injury. Although sporotrichosis should be considered for differential diagnosis in people working with soil and plants, cases of chronic lesions on skin of cats and in households is probably a new epidemiological approach in a given geographic region. © 2012 The International Society of Dermatology.

A five month old child with atopic dermatitis developed contact dermatitis to almond with positive patch test, positive prick test, and class 4 anti-almond IgE. Focal lesions of persistent eczema were correlated with application of almond oil for 2 month on cheeks and buttocks. The child had not ingested almond and her mother did not report almond intake during her breast-feeding. This observation points to the problems of possible percutaneous sensitisation to food proteins. The study of skin ointments containing components of food origin in 27 food sensitized atopic patients confirm that the choice of an ointment for lesional skin is of importance.

Background and objectives Nowadays, there are several noninvasive technologies being used for improving of body contouring. The objectives of this pilot study were to verify the effectiveness of the Heccus® device, emphasizing the synergism between nonfocused ultrasound plus Aussie current in the improvement of body contour, and to determine if the association of this therapy with whole-body vibration exercises can have additional positive effects in the results of the treatments. Subjects and methods Twenty healthy women aged 20–40 years participated in the study. Ten patients received Combined Therapy treatment (G1) and the other 10 participants received Combined Therapy with additional vibratory platform treatment (G2). Anthropometric and standardized photography analysis, ultrasonography, cutometry and self-adminestered questionnaires of tolerance and satisfaction levels with the treatment were used. Results Compared with baseline values, reduction of fat thickness was observed by ultrasonography in the posterior thigh area in the G1 group (P<0.05) and in the buttocks (P<0.05) and the posterior thigh areas (P<0.05) in the G2. All the treated areas in both groups showed reduction in cellulite degree in the buttocks, G1 (P<0.05) and G2 (P<0.05), and in posterior thigh areas, G1 (P<0.05) and G2 (P<0.05). Optimal improvement of skin firmness (G1, P<0.0001; G2, P=0.0034) in the treated areas was observed in both groups. Conclusion We conclude that the synergistic effects of the Combined Therapy (nonfocused ultrasound plus Aussie current) might be a good option with noninvasive body contouring treatment for improving the aspect of the cellulite, skin firmness and localized fat. If used in association with the whole-body vibratory platform, the results can be better, especially in the treatment of localized fat. Further studies with larger sample size should be performed to confirm these results. PMID:29731654

Experience with several, previously unreported, intentional face-first immersion burns led us to evaluate the distribution of inflicted and unintentional immersion scald burns in a hospital series. (1) Authors' clinical and legal practices; (2) Burn center at regional Level 1 trauma hospital. : (1) Case series of face-first, inflicted immersion burn victims; (2) Consecutive hospitalized scald burn victims younger than 5 years old, 1/3/1996 to 3/25/2000. (1) Individual case reports; (2) Retrospective records review. Simple descriptive statistics, Fisher Exact test and t test. (1) Six cases of inflicted head and neck immersion injury are described. Four were tap water and 2 food/drink scalds. (2) 22/195 hospitalized victims had sustained immersion burns, 13 from tap water and 9 from other fluids. Six (46%) tap water immersions and no (0%) other immersions had inflicted injuries (P = 0.05). Two of the tap water immersions and one other source immersion included burning of the head and neck. Of these, one tap water immersion, but no other immersion, was inflicted. In no patients were head and neck injuries the sole or predominant site of scalding. In all, 9 children sustained inflicted scalds. Bilateral lower extremity tap water immersion scalds occurred in 100% (6/6) of abusive and 29% (2/7) of unintentional injuries (P = 0.02). Buttock and perineal injuries occurred in 67% (4/6) inflicted versus 29% (2/7) unintentional tap water immersion scalds (P = 0.28). Other fluids caused bilateral lower extremity immersion burns in 3/9 (33 %) unintentionally injured patients, but no abused children (NS). Craniofacial immersion injury, although seen by the authors in legal cases, is infrequent. It was present incidentally in one inflicted tap water burn in the consecutive hospital series. This series affirms the predominance of bilateral lower extremity burns in inflicted tap water immersions. Buttock/perineal immersions were more common with abuse than with unintentional injury.

Effect of prolonged sitting on body-seat contact pressures among quay crane operators: A pilot study.

PubMed

2016-11-22

Quay crane operators are specialized in moving containers to and from vessels while adopting constrained sitting postures for prolonged periods (4-6 consecutive hours) in a very challenging environment. Thus, they are exposed to discomfort or pain that may result in deterioration of their performance with consequent reduction of operational safety levels. Such discomfort can be indirectly and partially assessed by measuring contact pressure at the body-seat interface. The aim of the study was to assess the feasibility, usefulness, and effectiveness of monitoring the variations in seat-body interface pressure during a regular work shift of 4 hours performed in a simulated environment. Eight professional operators performed a four-hour shift in a realistic control station set inside a quay crane simulator. Seat-body contact pressures were measured at 10 Hz using two pressure-sensitive mats placed on the seat pan and the backrest. Raw pressure data were processed to extract pressure vs. time curves related to the whole seat surface and, for the seat pan only, values associated with four anatomical regions (i.e. left and right thighs and buttocks). During the work shift, the mean backrest pressure was low and fairly constant. Seat pan pressure increased by 10%, rising from 7.4 (1.5) to 8.2 (2.3) kPa over the simulated shift. Detailed analysis of the four sub-regions revealed that as the trial progressed the mean contact pressure on buttocks decreased (-6% at the end of the trial) while thigh pressures increased (by 10 and 20% for right and left sides, respectively). Although further studies with larger samples are needed, long-term monitoring of the body-seat contact pressures of crane operators in a simulated environment appears to be a useful tool to identify specific postural strategies to reduce discomfort originated by prolonged sitting posture.

Vertical Vibration Transmission Through the Lumbar Spine of the Seated SUBJECT—FIRST Results

El-Khatib, A.; Guillon, F.; Dômont, A.

1998-08-01

Seven fresh, not embalmed, cadavers (58·1±6·6 years, 73±10·3 kg, 170·7±6·5 cm) were submitted, in the week following their death (7·1±3·1 days), to a whole-body vertical broad-band white random vibration in the bandwidth 0·8 to 25 Hz of about 1·5 m/s2r.m.s. Two postures were tested using the same rigid seat, each one with and without a lumbar support: seated erect and seated as in a car. Vibration was monitored on the floor, the seating in the vertical direction (buttocks-to-head), the five lumbar vertebrae and the sternum: vertical (buttocks to head) and longitudinal (back to chest). Biaxial accelerometers were mounted rigidly on the anterior face of the vertebral body, after the removal of the abdominal viscera. Analogue recordings of each channel were passed through an antialising filter (Fc=40 Hz) then sampled at 80 Hz (4096 samples/channel). The inclination of each accelerometer (α) was measured on the lateral X-ray taken for every trial, then the data were set in order to be in the same reference (Z=z/cos α,X=xcos α). Spectral analysis was performed with a frequency resolution of 0·3 Hz, on the basis of Welch's method. Thirty one overlapping sections (256 samples per section using a Hanning window with an overlap rate of 128 samples) of the estimated periodograms were averaged. Transfer and coherence functions were than estimated between the vertical seating acceleration and the measured accelerations at the upper levels. The first results showed that the vertical vibration transmission was constant throughout the lumbar spine. Inter-subject variability was the major source of disparity. Resonance phenomena were observed between 4 and 9 Hz and depended on posture.

Dermal carbonyl modification is related to the yellowish color change of photo-aged Japanese facial skin.

The photo-aged facial skin is characterized by various unique features such as dark spots, wrinkles, and sagging. Elderly people, particularly Asians, tend to show a yellowish skin color change with photo-aging. However, there has been no analytical study conducted on this unique skin color change of the aged facial skin. The purpose of the present study is to examine whether the carbonyl modification in the dermal protein is involved in the yellowish color change that occurs in the photo-aged skin. Normal skin samples excised from the face, abdomen and buttock of variously aged Japanese were separated into the epidermal and the dermal portions. These skin samples were histologically examined for carbonyl modification. Moreover, an in vitro constructed dermis model composed of a contracted collagen gel was treated with acrolein or 4-hydroxynonenal. All these samples were also studied colorimetrically. The dermal samples obtained from the photo-aged facial skin exhibited an appearance of yellowish color, whereas neither the facial epidermis nor the dermis obtained from the abdomen or buttock showed such a yellowish discoloration. The upper layer of the dermis that revealed the yellowish color showed elastosis whose elastic fibers were found to colocalize with carbonyl protein as detected by a labeled hydrazide, as well as by an immunohistochemical examination using the antibody against acrolein adduct. Experimental induction of carbonyl modification in a dermis model in vitro by a long-term treatment with acrolein or 4-hydroxynonenal was found to show the appearance of the yellowish change which was also proven by an increase in b* value of colorimetry. It was more pronounced than that induced by glycation. Our present results strongly suggest that carbonyl modification of the dermal protein is involved in the production of the yellowish color change that is noted in the photo-aged facial skin.

PELVIS or SACRAL syndrome denotes the association of local haemangioma and malformation in the pelvic region. In this paper, we report a case noteworthy on account of the initially livedoid appearance of the haemangioma as well as associated amniotic banding of an upper limb. A newborn male infant underwent left colostomy on the day of birth due to anal imperforation and anomalies of the external genital organs with sexual ambiguity. Examination of the skin and appendages revealed poorly delineated hypopigmentation in the sacrolumbar region and a fibrous groove around the right arm characteristic of amniotic band syndrome. Sacrolumbar and pelvic MRI scans revealed deviation towards the left of the last three sacral vertebrae with no medullary anomalies. Retrograde cystography showed a recto-uretral fistula. Progression of the infant's condition was marked by the appearance during the first month of a flat, violaceous, angiomatous, livedoid lesion in the middle of the buttocks and the perineum and a linear lesion on the rear aspect of the right lower limb. The skin biopsy of this lesion revealed a single capillary lobule at the dermal-hypodermal junction of non-specific appearance but with marked Glut1 expression by endothelial cells highly evocative of infantile haemangioma. Segmented haemangiomas are commonly associated with extracutaneous abnormalities. By analogy with PHACE syndrome, defined as association of segmented facial haemangioma with cerebral, ocular and cardio-aortic abnormalities, PELVIS/SACRAL syndrome denotes the association of segmented haemangioma of the loins (sacrolumbar region, buttocks or perineum=napkin haemangioma) with spinal dysraphia affecting the sacrolumbar spine, the terminal medullary cone, the genitourinary organs and the anal region to different degrees. Diagnosis of haemangioma associated with PELVIS/SACRAL syndrome may be delayed or complicated due to the macular, telangiectasic or livedoid appearance commonly seen. To our knowledge, there have been no reports to date of an association of amniotic banding with haemangioma or perineal dysraphia.

A young female presenting with unilateral sacroiliitis following dengue virus infection: a case report.

Dengue is a common arthropod-borne viral infection in Sri Lanka which is spread by the mosquitos of the genus Aedes. The clinical features of dengue include high-grade fever associated with arthralgia and myalgia. However, dengue virus is not considered an arthritogenic virus. We report a case of a previously healthy young female who presented with imaging-confirmed right-sided sacroiliitis 10 days after developing dengue fever. This is the first reported case that shows a possible link between dengue infection and development of arthritis. A 14-year-old Sri Lankan female presented to our medical unit with right buttock and hip pain of 3 weeks' duration. She had serologically confirmed dengue infection 10 days prior to the onset of buttock pain. A clinical examination revealed features of right sacroiliitis. An X-ray of her sacroiliac joint showed joint space widening and reactive bone changes. Magnetic resonance imaging of her pelvis and sacroiliac joint confirmed the diagnosis of acute sacroiliitis. She had an erythrocyte sedimentation rate of 110 mm first hour with a normal C-reactive protein. Her human leukocyte antigen-B27, rheumatoid factor, antinuclear antibody, chikungunya antibody, hepatitis serology, Brucella serology, and tuberculin skin test were negative. She was treated with nonsteroidal anti-inflammatory drugs and showed gradual improvement. After excluding possible causes for sacroiliitis, we postulated that sacroiliitis in the index case could have been caused or triggered by dengue virus infection. However there is a possibility that the sacroiliitis merely coincided with the dengue virus infection. This case illustrates the possibility that dengue virus could have a link with the development of arthritis in the same manner as other arthritogenic viruses; possible mechanisms for this include direct invasion of the synovium and the joint tissue by the virus, immune complex formation and deposition in the joint tissue, and immune dysregulation. Further studies are needed in this field to gain more knowledge, as dengue infection is highly prevalent in Sri Lanka.

To analyze the distribution of the musculoskeletal disorders, work load and working postures in different factories, gender, education levels, age and working years among manufacturing workers. In a cross-sectional study of 5134 manufacturing workers in 12 factories, the morbidities for musculoskeletal disorders in one year period were measured with questionnaires. The morbidities for musculoskeletal disorders in body sites: waist, neck, shoulder, wrist, ankle/feet, knee, hip/buttocks and elbows were 59.7%, 47.9%, 38.1%, 33.7%, 26.9%, 25.4%, 15.2%, and 14.9%, respectively in one year period. There were significant differences of morbidities for musculoskeletal symptoms in body sites of workers among different factories (P < 0.05 or P < 0.01). The morbidities of musculoskeletal symptoms in elbows, waist, wrists and ankle/feet of the workers in refractory material and chemical fiber factories were higher than those in other factories, the morbidities for musculoskeletal symptoms of workers in garments and diamond factories were lower than those in other factories. The morbidities for musculoskeletal symptoms in neck, shoulders and wrists of female workers were significantly higher than those of male workers (P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in body sites among workers with different educational levels (P < 0.05 or P < 0.01). There were significant differences of the morbidities for musculoskeletal symptoms in neck, shoulders, wrists, hip/buttocks and knee among groups with different age or different working years (P < 0.01), and the morbidities for musculoskeletal symptoms increased with age and working years. The proportions of unhealthy working postures and high working load among workers in refractory material and chemical fiber factories were higher; but those in garments and diamond factories were lower. The morbidities for musculoskeletal symptoms in waist, neck, shoulder and wrists of workers in manufacturing workers were higher; the gender, education level, age and working years could influenced the morbidities for musculoskeletal disorders.

Nowadays, there are several noninvasive technologies being used for improving of body contouring. The objectives of this pilot study were to verify the effectiveness of the Heccus ® device, emphasizing the synergism between nonfocused ultrasound plus Aussie current in the improvement of body contour, and to determine if the association of this therapy with whole-body vibration exercises can have additional positive effects in the results of the treatments. Twenty healthy women aged 20-40 years participated in the study. Ten patients received Combined Therapy treatment (G1) and the other 10 participants received Combined Therapy with additional vibratory platform treatment (G2). Anthropometric and standardized photography analysis, ultrasonography, cutometry and self-adminestered questionnaires of tolerance and satisfaction levels with the treatment were used. Compared with baseline values, reduction of fat thickness was observed by ultrasonography in the posterior thigh area in the G1 group ( P <0.05) and in the buttocks ( P <0.05) and the posterior thigh areas ( P <0.05) in the G2. All the treated areas in both groups showed reduction in cellulite degree in the buttocks, G1 ( P <0.05) and G2 ( P <0.05), and in posterior thigh areas, G1 ( P <0.05) and G2 ( P <0.05). Optimal improvement of skin firmness (G1, P <0.0001; G2, P =0.0034) in the treated areas was observed in both groups. We conclude that the synergistic effects of the Combined Therapy (nonfocused ultrasound plus Aussie current) might be a good option with noninvasive body contouring treatment for improving the aspect of the cellulite, skin firmness and localized fat. If used in association with the whole-body vibratory platform, the results can be better, especially in the treatment of localized fat. Further studies with larger sample size should be performed to confirm these results.

The prevalence of lipodystrophy ranges from 31 to 65%, depending on the criteria adopted for diagnosis. The usual methods applied in the diagnosis vary from self-perception, medical examination, skinfolds measurements, or even imaging assessment for confirmation of fat distribution changes. Although several methods have been developed, there is no gold standard for characterization of LA and LH, or mixed forms. This study aimed to compare self-reported signs of lipodystrophy with objective measures by skinfolds and circumferences, and to evaluate the prevalence of lipoatrophy (LA) and lipohypertrophy (LH) among subjects living with HIV/AIDS on ART. A cross-sectional study enrolled participants living with HIV/AIDS receiving ART, aged 18 years or older from an outpatient health care center, in Southern Brazil. Self-reported body fat enlargement in the abdomen, chest or breasts, and dorsocervical fat pad were used to determine LH, while LA was identified by self-reported fat wasting of the face, neck, legs, arms or buttocks. Measurements were obtained with a scientific caliper for infraorbital, buccal, and submandibular skinfolds, and using an inelastic tape to measure circumferences of waist, hip, neck, and arm. LH and LA were established by the presence of at least one self-reported sign. Comparisons of self-reported signs with objective measurements for men and women were carried out in 815 participants on ART, out of 1240 participants with HIV infection. Self-report of decreased facial fat and sunken cheeks was associated with lower infraorbital, buccal, and submandibular skinfolds. Participants who reported buffalo hump had, on average, greater neck circumference, as well as those who have increased waist circumference also reported abdominal enlargement, but no buttock wasting. Men were most commonly affected by lipoatrophy (73 vs. 53%; P < 0.001), and women by lipohypertrophy (79 vs. 56%; P < 0.001). In conclusion, self-reported signs of lipodystrophy and lipoatrophy are prevalent, differ by gender, and are associated with objective measurements in people living with HIV/AIDS.

The Morel-Lavallée lesion is a collection of serous fluid that develops after closed degloving injuries and after surgical procedures particularly in the pelvis and abdomen. It is a persistent seroma and is usually resistant to conservative methods of treatment such as percutaneous drainage and compression. Various methods of curative treatment have been reported in the literature, such as application of fibrin sealant, doxycycline, or alcohol sclerodhesis. We present a case of a huge recurrent Morel-Lavallée lesion in the lower back and buttock region that was treated with quilting sutures, fibrin sealant, and compression, with a review of the literature. © The Author(s) 2014.

Pyomyositis is a pyogenic infection of the skeletal muscles causing myalgia and fever in patients. Hematogenous seeding engendered by persistent bacteremia and septic embolism is usually the underlying cause of the disease. Trauma, intravenous drug use, and immunodeficiency are the main predisposing factors.Obturator internus pyomyositis with sciatica has not previously been reported. We report a rare case of a patient with subacute bacterial endocarditis presenting with left buttock pain and sciatica.Computed tomography confirmed the diagnosis of obturator internus pyomyositis. The patient was discharged uneventfully after successful antibiotic treatment.The mortality rate of patients who have pyomyositis comorbid with another condition or disease is extremely high. Early diagnosis and aggressive management are imperative.

Foreign body granuloma formation secondary to silicone injection.

2008-07-15

Injectable silicone has been used extensively over the last 40 years for soft tissue augmentation. Although considered biologically inert, this material has been implicated in a variety of adverse reactions including granulomas, disfiguring nodules, and lymphedema, sometimes with latent periods of decades. Often these complications are a result of the use of industrial grade products injected by unlicensed or unskilled practitioners. Here we report a case of foreign body granuloma in the thigh secondary to silicone injection in the buttocks. Initially the patient did not disclose a cosmetic contouring procedure administered by a nonprofessional nine months earlier, making diagnosis difficult. We remind clinicians to include foreign body granulomas in the differential diagnosis of apparent cellulitis and to question patients about the use of injectable fillers.

Fatal Fat Embolism After Penis Enlargement by Autologous Fat Transfer: A Case Report and Review of the Literature.

Fat embolism is an incidental finding in cases of long bone fractures or other trauma, but it is also associated with liposuction and autologous fat transfer, a procedure where fat from liposuction is injected back into the same patient's face, breast, buttocks or penis. We here present a case of sudden death by fat embolism in a healthy young male, caused by a simple penis enlargement procedure, in which fat was injected into the penis shaft. We suggest that the risk of fat embolization might be higher when pretraumatized tissue is subjected to fat injection, like in this case, where a penis elongation was performed before the fat injection. © 2017 American Academy of Forensic Sciences.

Wedgies-the upward yanking of another's underpants from the rear to wedge them between the buttocks-can be administered playfully, maliciously, or adventurously; at forces ranging from gentle to "atomic"; and with or without the foreknowledge or consent of the recipient. Wedgies have been documented anecdotally in the popular Internet literature, with chief emphasis on their sensation-seeking or momentary entertainment value to the giver and recipient. Most participants are typically young; however, we report the case of a 50-year-old man who sustained chronic, painless radiculitis after he received an unanticipated wedgie of moderate force. This report-apparently the first of its kind in the medical literature-serves as notice that exchanging wedgies is not merely a juvenile act or immature prank: the outcome can be injurious.

Biostereometric analysis of body form - The second manned Skylab mission

Results of biostereometric analyses of the body form of the Skylab 3 crew before and after flight. The Cartesian coordinates of numerous points on the body surface were derived by stereophotogrammetry, and mathematical analysis of the coordinate description allowed computation of the surface area and volume of the body, the volume of body segments, and the area and shape of cross sections. The weight loss in all three crew members was accompanied by a loss in volume distributed between the trunk and legs, with the legs showing the greatest proportional loss. The observed loss of volume apparently resulted from a combined loss of fluid in the abdomen and legs, of muscle in the legs and paraspinal region, and of fat in the abdomen and buttocks.

The factors that trigger reactivation in humans are still poorly defined. In our study, five patients with documented histories of recurrent herpes simplex virus infection on the buttocks or sacrum were exposed to three times their minimal erythema dose of ultraviolet light. Site-specific cutaneous herpes simplex virus infection occurred at 4.4 +/- 0.4 days after exposure to ultraviolet light in 8 of 13 attempts at reactivation. We conclude that ultraviolet light can reactivate herpesmore » simplex virus under experimentally defined conditions.

An accessory penis is a very rare anomaly. Only five cases have been reported thus far to our knowledge. We present the case of a child aged 2 years and 10 months who had a penis-like structure (containing phallus and glans) attached to the right buttock. Associated anomalies were a non-communicating type of colonic duplication, a paramedian stenosed anal opening, a horse-shoe kidney, posterior urethral valves, scoliosis of the lumbo-sacral spine, polydactyly and equino-varus deformity of the right foot. As far as we can tell, this is the first report of an accessory penis associated with colonic duplication and other congenital anomalies. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Piriformis muscle syndrome.

2006-01-01

Sciatica is characterized by radiating pain from the sacro-lumbar region to the buttocks and down to the lower limb. The causes of sciatica usually relate to degenerative changes in the spine and lesions to the intervertebral discs. Secondary symptomatic sciatica may by caused by metastases to the vertebra, tuberculosis of the spine, tumors located inside the vertebral channel, or entrapment of the sciatic nerve in the piriformis muscle. The piriformis syndrome is primarily caused by fall injury, but other causes are possible, including pyomyositis, dystonia musculorum deformans, and fibrosis after deep injections. Secondary causes like irritation of the sacroiliac joint or lump near the sciatic notch have been described. In the general practice the so-called posttraumatic piriformis muscle syndrome is common. The right treatment can be started following a thorough investigation into the cause of symptoms.

Lumbosacral transitional vertebra causing Bertolotti's syndrome: a case report and review of the literature.

2009-07-06

Lumbosacral transitional vertebra is an anatomical variation of the fifth lumbar vertebra in which an enlarged transverse process can form a joint or fusion with the sacrum or ilium. The association of that variant with low back pain and the change in the biomechanical properties of the lumbar spine is called Bertolotti's syndrome. We report a case of a 40-year-old male patient with chronic low back pain extending to the left buttock, just above the ipsilateral sacroiliac joint. Radiographic investigation revealed an anomalous enlargement of the left transverse process of the fifth lumbar vertebra forming a pseudarthrosis with the infrajacent ala of the sacrum. In young patients with back pain the possibility of Bertolotti's syndrome should always be taken in account.

2006-01-01

We report an unusual case of bilateral buttock claudication at ambulation of less than two blocks in a 57-year-old man with normal lower-extremity segmental pressure on noninvasive exercise testing. He was found to have bilateral high-grade internal iliac artery stenoses on arteriography. Both sides were successfully treated in a staged fashion via a contralateral approach with percutaneous transluminal angioplasty and a balloon-expandable stent, with complete symptom resolution. A clinical vascular examination with normal findings of the common iliac, external iliac, and common and superficial femoral arteries eliminates significant vascular obstruction as a cause of claudication. However, internal iliac occlusive disease may be suspected when symptoms are limited to the gluteal musculature and other causes are eliminated. Percutaneous interventions can be of diagnostic and therapeutic value.

2017-09-01

Bertolotti's syndrome is a spinal disorder characterized by abnormal enlargement of the transverse process of the most caudal lumbar vertebra. The L5 transverse process may be enlarged either unilaterally or bilaterally and may articulate or fuse with the sacrum or ilium. Pseudoarticulation between the transverse process of the L5 and the alar of the sacrum can cause buttock pain and leg pain. In addition, the L4 exiting nerve root could be compressed by an enlarged L5 transverse process. The authors could have obtained satisfactory results from the selected cases of Bertolotti's syndrome by applying a selective transverse processectomy of the L5. The objective of this study is to determine the effectiveness of L5 transverse processectomy for symptomatic Bertolotti's syndrome. A retrospective study. A total of 256 patients with Bertolotti's syndrome who had severe buttock pain and unilateral or bilateral radiating leg pain were selected. The correct diagnosis was made based on imaging studies which included computed tomography (CT), plain x-rays, and magnetic resonance imaging (MRI). The final diagnosis was made by confirming pain relief from anesthetic block. A total of 87 patients were classified into 2 groups: group A included 50 patients whose pain was relieved by block into the pseudoarticulation and group B included 37 patients whose pain was relieved by block into the L4 exiting nerve root. A total of 61 cases (group A: 39 cases, group B: 22 cases) were selected as pure L5 transverse processectomy. The primary outcome measures were reduction in pain scores and improvement in quality of life. Among 61 patients, there were 19 men and 42 women. The mean age of the patients was 53.2 ± 12 years (group A: 57.8 ± 14 years [16 - 86 years], group B: 53.4 ± 14 years [27 - 77 years]). The mean follow-up period was 6.5 months. The patients' mean visual analog scale (VAS) prior to surgery was 7.54 ± 0.81 (group A: 7.59 ± 0.93, group B: 7.50 ± 0.86), and the mean postoperative VAS was 2.86 ± 1.67 (group A: 3.82 ± 1.59, group B: 2.05 ± 1.00). According to Macnab's criteria, 12 patients showed excellent results (group A: 3, group B: 9), 41 patients showed good results (group A: 11, group B: 30), 6 patients showed fair results (group A: 5, group B: 1), and 2 patients showed poor results (group A: 2, group B: 0). Thus, satisfactory results were achieved in 86.89% of the cases. In patients with Bertolotti's syndrome, pseudoarticulation as well as L4 nerve root compression can be the source of buttock pain and lower extremity pain. Bisectional cutting of the L5 transverse process and decompression of the L4 nerve root could be an optimal treatment for Bertolotti's syndrome, and it may be easily approached by the paraspinal approach. This is a retrospective study and only offers one-year follow-up data for patients with Bertolotti's syndrome who have undergone L5 transverse process resection.Key words: Bertolotti's syndrome, pseudoarticulation, L5 transverse processectomy, paraspinal approach.

Simulations of skin and subcutaneous tissue loading in the buttocks while regaining weight-bearing after a push-up in wheelchair users.

PubMed

Levy, Ayelet; Kopplin, Kara; Gefen, Amit

2013-12-01

Pressure ulcers (PUs) are common in patients who chronically depend on a wheelchair for mobility, such as those with a spinal cord injury (SCI). In attempt to prevent the formation of PUs, pressure relieving maneuvers, such as push-ups, are commonly recommended for individuals with SCI. However, very little is known about skin and subcutaneous fat tissue load distributions during sitting and in particular their development during the process of regaining weight-bearing after a push-up. Knowledge on how these loads evolve during sitting-down is critical for understanding the susceptibility of skin to PUs. Considering the potential practical implications on guidelines for wheelchair users, we studied herein the build-up of shear loads in skin and subcutaneous fat using a model of the buttocks of a single SCI subject. Using 12 variants of our finite element (FE) model, we determined the shear loads in skin and subcutaneous fat tissues under the ischial tuberosities when sitting down on foam cushions with different stiffness properties, in healthy skin and scarred skin conditions, focusing on the time course of the build-up of tissue loads. We found substantial differences between the loading curves of skin and fat: While the fat was loaded at a nearly constant rate, skin loads increased nonlinearly - with a greater load/time slope at early skin-support contact. In the context of tissue health and prevention of PUs, this indicates that the more sensitive period with respect to skin integrity is at initial skin-support contact. We further found that the edges of a pre-existing scar are more susceptible to injury, and the greater risk for that is when a hypertrophic scar is present. Despite that this is a theoretical modeling study with associated limitations, we believe that it is already appropriate to recommend to patients to reposition themselves gradually and gently, and not to "fall" back into the wheelchair after finishing a push-up maneuver.

A Wireless Lingual Feedback Device to Reduce Overpressures in Seated Posture: A Feasibility Study

PubMed Central

Chenu, Olivier; Vuillerme, Nicolas; Demongeot, Jacques; Payan, Yohan

2009-01-01

Background Pressure sores are localized injuries to the skin and underlying tissues and are mainly resulting from overpressure. Paraplegic peoples are particularly subjects to pressure sores because of long-time seated postures and sensory deprivation at the lower limbs. Methodology/Principal Findings Here we report outcomes of a feasibility trial involving a biofeedback system aimed at reducing buttock overpressure whilst an individual is seated. The system consists of (1) pressure sensors, (2) a laptop coupling sensors and actuator (3) a wireless Tongue Display Unit (TDU) consisting of a circuit embedded in a dental retainer with electrodes put in contact with the tongue. The principle consists in (1) detecting overpressures in people who are seated over long periods of time, (2) estimating a postural change that could reduce these overpressures and (3) communicating this change through directional information transmitted by the TDU.Twenty-four healthy subjects voluntarily participated in this study. Twelve healthy subjects initially formed the experimental group (EG) and were seated on a chair with the wireless TDU inside their mouth. They were asked to follow TDU orders that were randomly spread throughout the session. They were evaluated during two experimental sessions during which 20 electro-stimulations were sent. Twelve other subjects, added retrospectively, formed the control group (CG). These subjects participated in one session of the same experiment without any biofeedback.Three dependent variables were computed: (1) the ability of subjects to reach target posture (EG versus CG), (2) high pressure reductions after a biofeedback (EG versus CG) and (3) the level of these reductions relative to their initial values (EG only). Results show (1) that EG reached target postures in 90.2% of the trials, against 5,3% in the CG, (2) a significant reduction in overpressures in the EG compared to the CG and (3), for the EG, that the higher the initial pressures were, the more they were decreased. Conclusions/Significance The findings suggest that, in this trial, subjects were able to use a tongue tactile feedback system to reduce buttock overpressure while seated. Further evaluation of this system on paraplegic subjects remains to be done. PMID:19888336

Study Design Retrospective case series. Objective StaXx XD (Spine Wave, Inc., Shelton, CT, United States) is an expandable polyaryl-ether-ether-ketone (PEEK) wafer implant utilized in the treatment of lumbar degenerative disease. PEEK implants have been successfully used as interbody devices. Few studies have focused on expandable PEEK devices. The aim of the current study is to determine the radiographic and clinical outcome of expandable PEEK cages utilized for transforaminal lumbar interbody fusion in patients with lumbar degenerative diseases. Methods Forty-nine patients who underwent lumbar interbody fusion with implantation of expandable PEEK cages and posterior instrumentation were included. The clinical outcome was evaluated using the visual analog scale (VAS) and the Oswestry Disability Index (ODI). Radiographic parameters including disk height, foraminal height, listhesis, local disk angle of the index level/levels, regional lumbar lordosis, and graft subsidence were measured preoperatively, postoperatively, and at latest follow-up. Results At an average follow-up of 19.3 months, the minimum clinically important difference for the ODI and VAS back, buttock, and leg were achieved in 64, 52, 58, and 52% of the patients, respectively. There was statistically significant improvement in VAS back (6.42 versus 3.11, p < 0.001), VAS buttock (4.66 versus 1.97, p = 0.002), VAS leg (4.55 versus 1.96, p < 0.001), and ODI (21.7 versus 12.1, p < 0.001) scores. There was a significant increase in the average disk height (6.49 versus 8.18 mm, p = 0.037) and foraminal height (15.6 versus 18.53 mm, p = 0.0001), and a significant reduction in the listhesis (5.13 versus 3.15 mm, p = 0.005). The subsidence of 0.66 mm (7.4%) observed at the latest follow-up was not significant (p = 0.35). Conclusions Midterm results indicate that expandable PEEK spacers can effectively and durably restore disk and foraminal height and improve the outcome without significant subsidence. PMID:26131383

The purpose of this study was to examine the effects of a skin barrier cream with moisturization and skin-protectant characteristics for improving the severity of incontinence-associated dermatitis (IAD) pertaining to the skin physiology and appearance. We measured the following outcomes: (1) skin physiological characteristics indicating skin protection and enhancement of the skin's moisture barrier (stratum corneum hydration, dermis hydration level, transepidermal water loss, and skin pH); and (2) changes in skin appearance (the degree of erythema and pigmentation, and the sulcus cutis condition). Single-blind, cluster randomized controlled trial. The study was conducted in a long-term care facility in Japan between November 7, 2011, and May 6, 2012. We used block randomization to obtain a random sample of 6 (4 experimental and 2 control) out of 10 available wards. All subjects were elderly women with IAD of the buttock or inner thigh. We assessed 295 patients, but only 33 met inclusion criteria; 18 were allocated to the experimental group and 15 were allocated to the control group. All participants were managed with cleansing with a skin cleanser and application of a moisturizer daily. In addition, a skin barrier cream designed to enhance the skin's moisture barrier and act as a protective barrier was applied to the skin of patients in the experimental group 3 times a day when absorptive briefs were changed. Skin physiological and appearance characteristics were scored only at the buttock or thigh area. All data were collected on days 1 and 14 of the study. Univariate analysis found that the erythema index was lower in the intervention group than in the control group at day 14 (P = .004). Multivariate analysis found significant associations between use of the skin barrier cream and increased stratum corneum hydration (β= .443, P = .031), decreased skin pH (β=-.439, P = .020), and magnitude of erythema (β=-.451, P = .018). Study findings suggest that a barrier cream designed to enhance the skin's moisture barrier and act as a skin protectant increased stratum corneum hydration, reduced cutaneous pH, and reduced erythema.

A 31-year-old Moroccan woman with no significant past medical history was seen during her second pregnancy. At 25 weeks gestation she was admitted with a febrile illness associated with a productive cough which was treated as a community acquired pneumonia with oral antibiotics. At 31 weeks gestation she was admitted with a tender swelling in the right groin and underwent incision and drainage of a presumed femoral abscess. At 36 weeks gestation she re-presented with multiple skin lesions on her arms, legs and buttocks. Initial investigation found no obvious cause for her presentation. The decision for induction of labour was taken as the patient was not improving, and resulted in an uncomplicated Caesarean delivery. After delivery, Mantoux and Quantiferon tests were reported to be positive and the patient was diagnosed with papulonecrotic tuberculides. PMID:22180755

Most cases of gas gangrene caused by Clostridium species begin with trauma-related injuries but in rare cases, spontaneous gas gangrene (SGG) can occur when patients have conditions such as advanced malignancy, diabetes, or immunosuppression. Clostridium perfringens, a rare cause of SGG, exists as normal flora of skin and intestines of human. Adequate antibiotics with surgical debridement of infected tissue is the only curative therapeutic management. Mortality rate among adults is reported range of 67-100% and majority of deaths are occurred within 24 hours of onset. We experienced a case of SGG on the trunk, buttock and thigh in a neutropenic patient with acute lymphoblastic leukemia. His clinical course was rapid and fatal during pre-engraftment neutropenic period of allogeneic stem cell transplantation.

Piriformis syndrome is a nondiscogenic cause of sciatica from compression of the sciatic nerve through or around the piriformis muscle. Patients typically have sciatica, buttocks pain, and worse pain with sitting. They usually have normal neurological examination results and negative straight leg raising test results. Flexion, adduction, and internal rotation of the hip, Freiberg sign, Pace sign, and direct palpation of the piriformis cause pain and may reproduce symptoms. Imaging and neurodiagnostic studies are typically normal and are used to rule out other etiologies for sciatica. Conservative treatment, including medication and physiotherapy, is usually helpful for the majority of patients. For recalcitrant cases, corticosteroid and botulinum toxin injections may be attempted. Ultrasound and other imaging modalities likely improve accuracy of injections. Piriformis tenotomy and decompression of the sciatic nerve can be done for those who do not respond.

Method and apparatus for waste collection and storage

NASA Technical Reports Server (NTRS)

Thornton, William E., Jr. (Inventor); Whitemore, Henry B. (Inventor)

1991-01-01

A method and apparatus are disclosed for collection of fecal matter designed to operate efficiently in zero gravity environment. The system comprises a waste collection area within a body having a seat opening. Low pressure within a waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undesirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, which valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pad to a face of the piston with each actuation.

Thirty years of anthropometric changes relevant to the width and depth of transportation seating spaces, present and future.

This paper reports the results of an investigation into changes in body shape anthropometry over the past several decades and discusses the impact of those changes on seating in transport, especially airliners. Changes in some body shape dimensions were confirmed in a sample of students at TU Delft; several of the changes, e.g. hip breadth, seated, are relevant to the ongoing design of seating. No change in buttock knee length was observed. The fit between current user anthropometry and current airline seat design, especially regarding seat width, was investigated. A comparison of the average current seat breadth with global anthropometric data suggests that accommodation may be problematic, with less than optimal width for passengers' shoulder and elbow widths.

Lumbosacral transitional vertebra causing Bertolotti’s syndrome: a case report and review of the literature

PubMed Central

Koutras, Georgios; Natsis, Konstantinos

2009-01-01

Introduction Lumbosacral transitional vertebra is an anatomical variation of the fifth lumbar vertebra in which an enlarged transverse process can form a joint or fusion with the sacrum or ilium. The association of that variant with low back pain and the change in the biomechanical properties of the lumbar spine is called Bertolotti’s syndrome. Case presentation We report a case of a 40-year-old male patient with chronic low back pain extending to the left buttock, just above the ipsilateral sacroiliac joint. Radiographic investigation revealed an anomalous enlargement of the left transverse process of the fifth lumbar vertebra forming a pseudarthrosis with the infrajacent ala of the sacrum. Conclusion In young patients with back pain the possibility of Bertolotti’s syndrome should always be taken in account. PMID:19830065

Varicella-associated purpura fulminans: chicken pox is not always benign.

2006-01-01

To report a 6-year-old boy with post-chicken pox purpura fulminans (PF). A 6-year-old boy presented with purpura of the legs that rapidly progressed to other parts of the limbs and the buttocks. The patient had had chicken pox 10 days prior to presentation. He was afebrile and the chicken pox lesions were dry. He received anti-coagulants, a large volume of fresh frozen plasma, immunoglobulin and steroids. The skin lesions regressed but both hands and parts of the lower limbs remained necrotic; the patient was transferred to an orthopaedic hospital for amputation and skin grafting. This case report shows that PF can occur as a post-infection syndrome after primary varicella. Early and aggressive treatment of post-chicken pox PF might reduce the mortality and morbidity associated with this condition. Copyright 2006 S. Karger AG, Basel.

Fabry disease is a rare lysosomal storage disorder, inherited in an X-linked manner. It is characterized by the deficiency of the enzyme alpha-galactosidase, leading to a buildup of glycosphingolipids in the cells. Angiokeratoma is one of the cutaneous manifestations of this condition, and it helps making the diagnosis. The typical site involves the genital area in men and lumbosacral, buttocks and trunk region in both sexes. We report a case of genital angiokeratoma in a woman with Fabry disease. The diagnosis is through molecular analysis and, when made early, starting treatment reduces the morbidity and mortality of the disease. Thus, the dermatologist has an important role in the identification of angiokeratoma as a cutaneous marker, and the knowledge of its different presentations is essential for the early diagnosis and management of Fabry disease.

Most cases of gas gangrene caused by Clostridium species begin with trauma-related injuries but in rare cases, spontaneous gas gangrene (SGG) can occur when patients have conditions such as advanced malignancy, diabetes, or immunosuppression. Clostridium perfringens, a rare cause of SGG, exists as normal flora of skin and intestines of human. Adequate antibiotics with surgical debridement of infected tissue is the only curative therapeutic management. Mortality rate among adults is reported range of 67-100% and majority of deaths are occurred within 24 hours of onset. We experienced a case of SGG on the trunk, buttock and thigh in a neutropenic patient with acute lymphoblastic leukemia. His clinical course was rapid and fatal during pre-engraftment neutropenic period of allogeneic stem cell transplantation. PMID:25298910

Researches on DH have shown that it is not just a bullous skin disease, but a cutaneous-intestinal disorder caused by hypersensitivity to gluten. Exposure to gluten is the starting point of an inflammatory cascade capable of forming autoantibodies that are brought to the skin, where they are deposited, culminating in the formation of skin lesions. These lesions are vesico-bullous, pruritic, and localized especially on elbows, knees and buttocks, although atypical presentations can occur. Immunofluorescence of perilesional area is considered the gold standard for diagnosis, but serological tests help in cases where it is negative. Patients who follow glutenfree diets have better control of symptoms on the skin and intestine, as well as lower risks of progression to lymphoma. Dapsone remains the main drug for treatment, but it requires monitoring of possible side effects, some potentially lethal. PMID:25387490

We report a case of pyodermia chronica glutealis complicated by acromegalic gigantism associated with hyperprolactinemia. The serum prolactin, growth hormone, adrenocorticotropic hormone, and 11-deoxycortisol levels were elevated, but the estradiol and dehydroepiandrosterone-sulphate levels were within normal limits. However, the testosterone level was very low. Histopathologically, we found sinus tracts and scarring in a specimen from the buttocks. We could not immunohistochemically detect clear androgen, growth hormone, or prolactin receptors at any site. The patient was a man with a height of 197 cm and weight of 140 kg, he had clinical features of active acromegaly such as excessive sweating and increased thickness of soft tissue. He was also diagnosed with diabetes mellitus. Under such conditions, bacteria could easily grow and lesions might have been aggravated by the heavy pressure from his weight, a possible causes of his pyodermia chronica glutealis.

Assessment of body perception among Swedish adolescents and young adults.

To assess body perception in adolescents and young adults without anorexia nervosa. Using a visual size estimation technique, perceived body size was estimated in four groups of Swedish adolescents and young adults without anorexia nervosa (86 males and 95 females). Perceived body size was estimated at nine different body sites comparing these estimations to real body size. The results show that 95% of males and 96% of females overestimated their body size (mean overestimation: males +22%, females +33%). The overestimations were greatest in females. The greatest overestimations were made of the waist (males +31%, females +46%), buttocks (males +22%, females +42%), and thighs (males +27%, females +41%). The results indicate that overestimation of body size may be a general phenomenon in adolescents and young adults in a country such as Sweden, implying a similar, but less pronounced distortion of body image as in individuals with anorexia nervosa.

Morel-Lavallee Lesions-Review of Pathophysiology, Clinical Findings, Imaging Findings and Management.

PubMed

2017-04-01

Morel-Lavallee lesion is a post-traumatic soft tissue degloving injury. This is commonly associated with sports injury caused by a shearing force resulting in separation of the hypodermis from the deeper fascia. Most common at the greater trochanter, these injuries also occur at flank, buttock, lumbar spine, scapula and the knee. Separation of the tissue planes result in a complex serosanguinous fluid collection with areas of fat within it. The imaging appearance is variable and non specific, potentially mimicking simple soft tissue haematoma, superficial bursitis or necrotic soft tissue neoplasms. If not treated in the acute or early sub acute settings, these collections are at risk for superinfection, overlying tissue necrosis and continued expansion. In this review article, we discuss the clinical presentation, pathophysiology, imaging features and differential diagnostic considerations of Morel-Lavallee lesions. Role of imaging in guiding prompt and appropriate treatment has also been discussed.

Multifocal soft tissue sarcoma is a rare clinical entity occurring in 1% of patients with extremity soft tissue sarcoma and in 4.5% of patients with liposarcoma. Multifocal disease may arise either synchronously or metachronously and has been associated with poor prognosis. Herein, we have described a rare case of metachronous multifocal myxoid liposarcoma involving the gastrointestinal tract that developed 14 months after the resection of a myxoid buttock liposarcoma. Diagnostic evaluation and management of the patient are discussed along with a review of the relevant literature. We conclude that multifocal myxoid liposarcoma is a rare clinical entity that usually represents metastatic disease with poor prognosis. A thorough imaging and careful physical examination are essential in the preoperative evaluation and postoperative follow-up of patients with myxoid extremity liposarcomas, as these tumors are known to have a tendency to spread toward extrapulmonary sites, frequently without pulmonary metastases.

Anterior sacroiliac joint plate fixation for unstable pelvic ring fractures avoids soft tissue problems in the buttocks; however, the lumbosacral nerves lie in close proximity to the sacroiliac joint and may be injured during the procedure. A 49 year-old woman with a type C pelvic ring fracture was treated with an anterior sacroiliac plate using a computed tomography (CT)-three-dimensional (3D)-fluoroscopy matching navigation system, which visualized the lumbosacral nerves as well as the iliac and sacral bones. We used a flat panel detector 3D C-arm, which made it possible to superimpose our preoperative CT-based plan on the intra-operative 3D-fluoroscopic images. No postoperative complications were noted. Intra-operative lumbosacral nerve visualization using computer navigation was useful to recognize the 'at-risk' area for nerve injury during anterior sacroiliac plate fixation.

2016-06-01

Synopsis Proximal hamstring tendinopathy (PHT) typically manifests as deep buttock pain at the hamstring common origin. Both athletic and nonathletic populations are affected by PHT. Pain and dysfunction are often long-standing and limit sporting and daily functions. There is limited evidence regarding diagnosis, assessment, and management; for example, there are no randomized controlled trials investigating rehabilitation of PHT. Some of the principles of management established in, for example, Achilles and patellar tendinopathy would appear to apply to PHT but are not as well documented. This narrative review and commentary will highlight clinical aspects of assessment and management of PHT, drawing on the available evidence and current principles of managing painful tendinopathy. The management outline presented aims to guide clinicians as well as future research. J Orthop Sports Phys Ther 2016;46(6):483-493. Epub 15 Apr 2016. doi:10.2519/jospt.2016.5986.

The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undersirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect the fecal matter, scrub the waste collection area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, so the valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pads to a face of the piston with each actuation.

Nursery, gutter, or anatomy class? Obscene expression in consumer health

PubMed Central

Smith, Catherine Arnott

2007-01-01

This paper presents results of a consumer health vocabulary study of text appearing on Web-based bulletin boards. Consumers used obscenities and euphemisms to refer to certain body parts, functions, and behaviors. The female genitalia are the body region most often described with an obscenity (29% of all instances); male genitalia, in contrast, were rendered as obscene only 3% of the time. Consumers responding on the bulletin boards appear genuinely to prefer euphemistic slang and baby talk (62%) over obscenities (24%) when referring to the buttocks. From an anatomical perspective, this large dataset reveals a consumer health vocabulary of euphemisms and outright obscenities coexisting with professional medical terminology. The evident preference for euphemisms and slang for some anatomical parts has important implications for the design of health information controlled vocabularies and translation systems, faced with a lay language more informal than expected.

Lethal donkey attacks have very rarely been described. The case of a 65-year-old man who was found deceased on a country road with 2 domestic donkeys nearby is, therefore, reported. Examination of the body revealed contusions and lacerations of the face and scalp, a comminuted fracture of the left maxilla, comminuted fracturing of the right radius and ulna and of the left anterior superior iliac spine, a flail chest, and pulmonary contusions. In addition, there were bite marks on the left thigh, right buttock, right axilla/upper arm, and left cheek which corresponded to the dental arcades of the donkeys. Death had resulted from blunt chest trauma due to an attack by 1 or 2 donkeys. Deaths and serious injuries are much more commonly caused by horses; however, this case shows that even domesticated donkeys may also rarely be capable of inflicting significant trauma and so should be approached with circumspection.

Childhood burns in south eastern Nigeria.

1997-06-01

In a ten year retrospective study of burns in children in University of Calabar Teaching Hospital (UCTH), Calabar, the main causes were hot water, hot soup or oil (56.6%) involving children mostly in the one to three year age group. The relative safety of the home environment seen in other forms of paediatric trauma is not observed in burns in children. A changing pattern of burns in children has emerged within the region with naked flames/bush fire coming second and affecting 22.7% of the children. Chemical burns hitherto a rare occurrence is now frequent because of the storage of caustic soda and acids in living rooms by soap making parents. Burns affecting the perineum, axilla and buttocks are difficult to keep clean and frequently lead to infections, with associated increased morbidity. Causes of childhood burns are largely preventable requiring active social/medical education and public enlightenment campaigns on the various methods of prevention.

A 72-year-old man with a history of metastatic melanoma presented with a two-day history of erythematous and edematous plaques, with scattered bullae on the neck, chest, axillae, and inguinal and gluteal folds, which began five days after infusion of an experimental drug. The clinical and histopathologic findings were consistent with systemic drug-related intertriginous and flexural exanthema (SDRIFE), which is an uncommon drug reaction that results in symmetric erythema that affects the buttocks, groin, and/or thighs as well other flexural folds. The clinical manifestations of SDRIFE are highly characteristic and include distinctive primary cutaneous lesions with a specific distribution and course; however, heterogeneity exists with respect to histopathologic features, skin test results, and in vitro investigations. The exact mechanism of SDRIFE remains unknown but is thought to result from a type IV delayed hypersensitivity immune response. Treatment is symptomatic and includes topical or oral glucocorticoids.

Piriformis syndrome is an uncommon cause of buttock and leg pain. Some treatment options include the injection of piriformis muscle with local anesthetic and steroids. Various techniques for piriformis muscle injection have been described. Ultrasound allows direct visualization and real time injection of the piriformis muscle. We describe 5 consecutive patients, diagnosed of piriformis syndrome with no improvement after pharmacological treatment. Piriformis muscle injection with local anesthetics and steroids was performed using an ultrasound technique based on a standard technique. All 5 patients have improved their pain measured by numeric verbal scale. One patient had a sciatic after injection that improved in 10 days spontaneously. We describe an ultrasound-guided piriformis muscle injection that has the advantages of being effective, simple, and safe.

A 50-year-old man, a known case of human immunodeficiency virus infection for the past 1 year, was on antiretroviral therapy in the form of stavudine, lamivudine, and nevirapine. Three days after replacing stavudine with tenofovir, he developed redness on the face and neck and within 48 h the rash became generalized. Dermatological examination revealed involvement of photoexposed areas of the face in the form of erythema and ill-defined hyperpigmented plaques, with mild periorbital edema. There was specific involvement of V and nape of the neck. Extensive erythema and scaling were also present on buttocks, thighs, and upper third of legs. A diagnosis of photoallergic dermatitis to tenofovir was considered and confirmed by histopathology and photopatch test. He responded well to the stoppage of the drug and oral corticosteroids. This is the first report of a photoallergic reaction to tenofovir in the literature. PMID:23112433

A 61-year-old woman with systemic lupus erythematosus and Sjögren syndrome presented with a two-month history of symptomatic nodules on the buttocks and thighs that progressed to involve the dorsal aspects of the hands. On examination, infiltrative papules, nodules, and plaques were present in these regions. Biopsy specimens demonstrated granulomatous inflammation and acid-fast bacilli with the use of a Fite stain, although a culture and polymerase chain reaction analysis were negative. The patient continues to improve on long-term clarithromycin therapy. Atypical mycobacterial infections are becoming more common, especially in immunocompromised patients. Antimicrobial therapy, either with a single agent or multiple agents, often is prolonged. A high index of suspicion is warranted in immunocompromised patients, which includes those with connective-tissue diseases that are active or that require immunosuppression. In these patients, the differential diagnosis includes infectious as well as inflammatory, reactive, or neoplastic processes.

Progressive symmetric erythrokeratodermia (PSEK) is characterized by symmetric and growing erythematous hyperkeratotic patches over the body shortly after birth, particularly trunk and limbs, the buttocks, and the face, sometimes together with palmoplantar keratoderma (PPK). The GJB2, GJB3, GJB4, GJB6, ARS (Component B), and LOR gene mutation might contribute to PSEK manifestation. This study aimed to identify sequence alteration of these genes in a Chinese PSEK patient with pseudoainhum. Genomic DNA was purified from the patient's peripheral blood. Mutation analysis of target genes was performed by direct sequencing using ABI 3730 sequencer No exonic mutations was identified in the aforementioned genes. The result underlines the genetic heterogeneity of PSEK and other related erythrokeratodermas. © 2014 The International Society of Dermatology.

1981-01-01

The final design and hardware fabrication was completed for an active control system capable of the required flutter suppression, compatible with and ready for installation in the NASA aeroelastic research wing number 1 (ARW-1) on Firebee II drone flight test vehicle. The flutter suppression system uses vertical acceleration at win buttock line 1.930 (76), with fuselage vertical and roll accelerations subtracted out, to drive wing outboard aileron control surfaces through appropriate symmetric and antisymmetric shaping filters. The goal of providing an increase of 20 percent above the unaugmented vehicle flutter velocity but below the maximum operating condition at Mach 0.98 is exceeded by the final flutter suppression system. Results indicate that the flutter suppression system mechanical and electronic components are ready for installation on the DAST ARW-1 wing and BQM-34E/F drone fuselage.

Linear IgA dermatosis has been increasingly associated with inflammatory bowel diseases, particularly ulcerative colitis. A 13-year-old male patient with an 11-month history of ulcerative colitis developed vesicles, pustules and erosions on the skin of the face, trunk and buttocks and in the oral mucosa. The work-up revealed a neutrophil-rich sub-epidermal bullous disease and linear deposition of IgA along the dermoepidermal junction, establishing the diagnosis of linear IgA dermatosis. The patient experienced unsatisfactory partial control of skin and intestinal symptoms despite the use of adalimumab, mesalazine, prednisone and dapsone for some months. After total colectomy, he presented complete remission of skin lesions, with no need of medications during two years of follow-up. A review of previously reported cases of the association is provided here and the role of ulcerative colitis in triggering linear IgA dermatosis is discussed.

Acute Compartment Syndrome Which Causes Rhabdomyolysis by Carbon Monoxide Poisoning and Sciatic Nerve Injury Associated with It: A Case Report.

PubMed

Ji, Jung-Woo

2017-09-01

Rhabdomyolysis is most frequently caused by soft tissue injury with trauma to the extremities. Non-traumatic rhabdomyolysis may be caused by alcohol or drug abuse, infection, collagen disease, or intensive exercise, but incidence is low. In particular, rhabdomyolysis resulting from carbon monoxide poisoning is especially rare. If caught before death, carbon monoxide poisoning has been shown to cause severe muscle necrosis and severe muscle damage leading to acute renal failure. In cases of carbon-monoxide-induced rhabdomyolsis leading to acute compartment syndrome in the buttocks and sciatic nerve injury are rare. We have experience treating patients with acute compartment syndrome due to rhabdomyolysis following carbon monoxide poisoning. We report the characteristic features of muscle necrosis observed during a decompression operation and magnetic resonance imaging findings with a one-year follow-up in addition to a review of the literature.

Pulsed Radiofrequency Application for the Treatment of Pain Secondary to Sacroiliac Joint Metastases.

2016-01-01

Sacroiliac (SI) joint pain can result from degeneration, infection, malignancy, and trauma. Patients with metastatic bone pain who do not respond to conventional treatment may need more aggressive neuroinvasive approaches. Recently, pulsed radiofrequency (PRF) neuromodulation has emerged as a promising treatment alternative for refractory cases of SI joint pain. Nevertheless, there is no report on the treatment of pain arising from SI joint metastases with PRF. We are reporting about a 63-year-old woman suffering from buttock pain due to breast cancer metastases in the SI joint. We treated this patient with PRF neuromodulation of the L4-S3 primary dorsal rami and lateral branches using a rotating curved needle technique. The patient tolerated the procedures well, without any complications. She experienced about 70% reduction in pain, and pain relief was sustained for 10 months. This result suggests that PRF neuromodulation is a safe, effective treatment for pain from SI joint metastases.

Finite element models of the thigh-buttock complex for assessing static sitting discomfort and pressure sore risk: a literature review.

2018-03-01

Being seated for long periods, while part of many leisure or occupational activities, can lead to discomfort, pain and sometimes health issues. The impact of prolonged sitting on the body has been widely studied in the literature, with a large number of human-body finite element models developed to simulate sitting and assess seat-induced discomfort or to investigate the biomechanical factors involved. Here, we review the finite element models developed to investigate sitting discomfort or risk of pressure sores. Our study examines finite element models from twenty-seven papers, seventeen dedicated to assessing seating discomfort and ten dedicated to investigating pressure ulcers caused by prolonged sitting. The models' mesh composition and material properties are found to differ widely. These models share a lack of validation and generally make little allowance for anthropometric diversity.

Type 2 segmental manifestation of autosomal dominant dermatoses refers to pronounced segmental lesions superimposed on the ordinary nonsegmental phenotype, indicating loss of heterozygosity occurring at an early stage of embryogenesis. We describe a 20-year-old Taiwanese woman with typical lesions of neurofibromatosis type 1 (NF1) in the form of characteristic café-au-lait spots, neurofibromas, axillary freckling and Lisch nodules. In addition, a giant garment-like or "bathing-trunk" café-au-lait macule involved the lower half of the trunk, the buttocks, and parts of the thighs, being superimposed on the ordinary smaller spots of NF1. This large café-au-lait macule may be best explained as an example of type 2 segmental NF1. A novel mutation (3009delG) in exon 23 was also identified in this patient, which has not yet been described in sporadic and familial NF1.

Apparatus for waste collection and storage

NASA Technical Reports Server (NTRS)

Thornton, Jr., William E. (Inventor); Whitmore, Henry B. (Inventor)

1989-01-01

An apparatus for collection of fecal matter designed to operate efficiently in a zero gravity environment. The system comprises a waste collection area within a body having a seat opening. Low pressure within the waste collection area directs fecal matter away from the user's buttocks and prevents the escape of undesirable gases. The user actuates a piston covered with an absorbent pad that sweeps through the waste collection area to collect fecal matter, scrub the waste collector area, press the waste against an end of the waste collection area and retracts, leaving the used pad. Multiple pads are provided on the piston to accommodate multiple uses of the system. Also a valve allows air to be drawn through the body, which valve will not be plugged with fecal matter. A sheet feeder feeds fresh sheets of absorbent pad to a face of the piston with each actuation.

Safety harness

1993-01-01

A safety harness to be worn by a worker, especially a worker wearing a plastic suit thereunder for protection in a radioactive or chemically hostile environment, which safety harness comprises a torso surrounding portion with at least one horizontal strap for adjustably securing the harness about the torso, two vertical shoulder straps with rings just forward of the of the peak of the shoulders for attaching a life-line and a pair of adjustable leg supporting straps releasibly attachable to the torso surrounding portion. In the event of a fall, the weight of the worker, when his fall is broken and he is suspended from the rings with his body angled slightly back and chest up, will be borne by the portion of the leg straps behind his buttocks rather than between his legs. Furthermore, the supporting straps do not restrict the air supplied through hoses into his suit when so suspended.

The formulation of recommendations on the use of wound dressings in pressure ulcer prevention was undertaken by a group of experts in pressure ulcer prevention and treatment from Australia, Portugal, UK and USA. After review of literature, they concluded that there is adequate evidence to recommend the use of five-layer silicone bordered dressings (Mepilex Border Sacrum(®) and 3 layer Mepilex Heel(®) dressings by Mölnlycke Health Care, Gothenburg, Sweden) for pressure ulcer prevention in the sacrum, buttocks and heels in high-risk patients, those in Emergency Department (ED), intensive care unit (ICU) and operating room (OR). Literature on which this recommendation is based includes one prospective randomised control trial, three cohort studies and two case series. Recommendations for dressing use in patients at high risk for pressure injury and shear injury were also provided. © 2014 The Authors.

2009-11-01

An amelanotic malignant melanoma is characterized by little or no pigment. It is frequently misdiagnosed because it is a rare entity in general, and because of its unusual clinical features. Liposarcoma is one of the most common adult soft tissue sarcomas. We encountered a case of amelanotic melanoma with a concurrent liposarcoma. A 68-year-old man presented with a single, 1.5x1.5 cm round erythematous, eroded nodule on the left heel. A biopsy specimen showed atypical, pleomorphic tumor cells with little melanin pigment. The tumor cells were positive for S-100, HMB-45 and negative for cytokeratins. These findings were consistent with amelanotic melanoma. On positron emission tomography/computed tomography (PET/CT), a hypermetabolic lesion was found in the left buttock. This lesion was excised and diagnosed as a well-differentiated liposarcoma. An association between sarcomas and other primary malignancies has been reported. However, an association between melanoma and liposarcoma is rare.

[Simulation of homicide to hide child's suicide].

2001-01-01

A case of pretending a homicide to conceal a child suicide is reported in which characteristic findings of the postmortem examination and conclusions from the analysis of forensic autopsy series provided substantial support for the police investigation. In the late night hours of a spring day the police authorities were informed that a 10-year-old girl had been found dead on a playground near its parents' house. As injuries of the neck were recognized by the police officers a homicide investigation was initiated. The post mortem examination showed a furrow symmetrically slanting from the front to the nape of the neck, discrete punctate haemorrhages of the skin of the face and numerous 'tram-line' bruises of the back, buttocks and extremities. These findings indicated as cause and manner of death suicidal hanging following corporal punishment. Confronted with these conclusions the mother immediately made a corresponding confession.

Nonhygienic behavior likely contributed to three recreational waterborne illness (RWI) outbreaks at Idaho splash parks. The study described in this article examined the influence of signage and hygiene attendant presence on rates of nonhygienic behavior among children at splash parks and knowledge and attitudes of their adult supervisors. Investigators observed children for nonhygienic behaviors at four Idaho splash parks, two with signage and attendants. Supervisors were surveyed (N = 551) using an eight-item survey. Individually observed children (N = 145) were often seen exposing their buttocks to splash feature water and placing an open mouth to water. The rate of nonhygienic behaviors was not lower at parks with signage or staff. Supervisors reported bathing children before splash park entry infrequently. Signage and hygiene attendants do not adequately limit nonhygienic behaviors at splash parks, and supervisors have insufficient understanding of RWI. These findings have implica.tions for developing splash park regulations and RWI prevention efforts.

2009-03-01

The present study evaluates the effect of a classroom-based behavioral intervention package to improve Japanese elementary school children's sitting posture in regular classrooms (N=68). This study uses a multiple-baseline design across two classrooms with a modified repeated reversal within each class. The article defines appropriate sitting posture as behavior composed of four components (feet, buttocks, back, and a whole body). The intervention package includes modeling, correspondence training, prompt, and reinforcement, among others. The authors counted the number of children with appropriate sitting posture in each classroom across all 28 sessions throughout the study. Interobserver agreement of appropriate sitting posture ranged from 80% to 100%. As a result of the intervention, the mean proportion of children with appropriate posture increased from approximately 20% to 90%. In addition, their academic writing productivity increased with the improved sitting posture. Teachers' acceptance of the intervention program proved to be excellent.

Pressure ulcers are a type of local soft tissue injury due to sustained mechanical loading and remain a common issue in patient care. People with spinal cord injury (SCI) are especially at risk of pressure ulcers due to impaired mobility and sensory perception. The development of load improving support structures relies on realistic tissue load evaluation e.g. using finite element analysis (FEA). FEA requires realistic subject-specific mechanical properties and geometries. This study focuses on the effect of geometry. MRI is used for the creation of geometrically accurate models of the human buttock for three able-bodied volunteers and three volunteers with SCI. The effect of geometry on observed internal tissue deformations for each subject is studied by comparing FEA findings for equivalent loading conditions. The large variations found between subjects confirms the importance of subject-specific FEA.

Shower PUVA: a novel variant of photochemotherapy. Distribution of photosensitivity and accumulation of trioxsalen in the skin.

Shower PUVA is a new variant of photochemotherapy suitable for therapy of various skin disorders. Psoralen, e.g. trioxsalen-containing water recirculates in a closed shower system and wets the skin continuously. After showering, whole-body UVA irradiation (320-400 nm) is performed. In order to prove the equal distribution of photosensitivity in vivo minimal phototoxic dose (MPD) was determined in different skin areas of healthy individuals. Additionally, we investigated the accumulation of trioxsalen in psoriasis lesions under the conditions described by quantifying psoralen in scales collected after showering. In a randomized study 20 healthy volunteers (skin type I-III) took showers for 5 and 10 min in trioxsalen (0.27 mg/l)-containing water at 37 degrees C. Immediately afterwards, MPD was tested on the inside of the upper arms and on the buttocks by using a polychromator light source (315-400 nm). The applied UVA doses were 0.06-0.75 J/cm(2) with steps of 0.125 J/cm(2). MPD was evaluated after 72 h. Equal distribution of photosensitivity was defined as equal MPD on the insides of the upper arm and the buttocks (+/-0.125 J/cm(2)). Skin scales of 21 patients with psoriasis were collected by scratching after showering with trioxsalen-containing water (0.27 mg/l) for 5 min. For quantification of trioxsalen in the scales HPLC was performed. An equal distribution of photosensitivity was achieved in 70% (14/20) cases after 10-min showering in trioxsalen-containing water. Showering for 5 min only revealed a 30% (6/20) rate of equal distributed photosensitivity. After 10-min shower time MPD was 0.325 J/cm(2) (median; range: 0.06-0.625 J/cm(2)). The average amount of trioxsalen found in the scales was 2.03 ng/mg scales (range: 0.38-7.2 ng/mg). For shower PUVA using trioxsalen, 10 min shower time is recommended to achieve sufficient distribution of photosensitivity on the skin. Clinical efficacy of shower PUVA can be explained by skin accumulation of trioxsalen which enters from the aqueous phase into the upper skin layers in detectable amounts. This is the first report demonstrating the efficacy of shower PUVA which in short shower time allows an uptake of psoralen by the skin. Copyright 2004 S. Karger AG, Basel

The objective of this study was to assess outcomes of a hybrid technique for treatment of abdominal aortic aneurysm (AAA) associated with iliac aneurysm without distal neck by combining an AAA endovascular repair approach with open surgery for preservation of the internal iliac artery (IIA). The files of 51 patients operated on between 1998 and 2017 in a single vascular surgery department were retrospectively analyzed. Inclusion criteria were patients with AAA associated with uni-iliac or bi-iliac aneurysm without suitable distal sealing zone. Surgery consisted of deployment of an aortouni-iliac stent graft combined with an extra-anatomic crossover prosthetic bypass. With use of a limited retroperitoneal approach, the contralateral proximal common iliac aneurysm was surgically excluded and the IIA revascularized by direct ilioiliac anastomosis or terminal common iliac suture, preserving the iliac bifurcation. The patients' mean age was 74 years (58-88 years), and 92% were men. The mean follow-up was 5.8 years (0.1-18 years). Twenty-nine patients (57%) had one or more high-risk criteria for open surgery. Nineteen patients (37.3%) had aortouni-iliac aneurysms, 19 (37.3%) aortobi-iliac aneurysms, 5 (10%) isolated iliac aneurysms, and 8 (15.7%) bi-iliac aneurysms without aortic location. Four patients (7.8%) also had IIA aneurysms. Surgery was successful in all cases. Two patients (4%) died during the 30 days after surgery. One surgically preserved IIA occluded within the first month, resulting in buttock claudication. The 5-year IIA primary patency rate was 96%. Type I proximal endoleaks occurred in two patients, requiring additional surgery 3 years and 13 years after the initial surgery, respectively. This hybrid technique, consisting of AAA endovascular exclusion combined with open IIA revascularization, is safe and effective for preservation of pelvic vascularization. It is associated with long-term patency and low morbidity rates. We have been using this technique since before the advent of branched dedicated devices, allowing preservation of the IIA with good results. This technique should continue to be proposed, especially in patients not eligible for endovascular iliac branch repair because of anatomic contraindications, to avoid pelvic ischemia if the IIA has to be sacrificed.

From July 13, 1988, to May 14, 1995, 1585 patients with burns and no other injuries besides inhalation were treated; 4.5% did not survive. Artificial neural networks were trained on patient presentation data with known outcomes on 90% of the randomized cases. The remaining cases were then used to predict survival and length of stay in cases not trained on. Survival was predicted with more than 98% accuracy and length of stay to within a week with 72% accuracy in these cases. For anatomic area involved by burn, burns involving the feet, scalp, or both had the largest negative effect on the survival prediction. In survivors burns involving the buttocks, transport to this burn center by the military or by helicopter, electrical burns, hot tar burns, and inhalation were associated with increasing the length of stay prediction. Neural networks can be used to accurately predict the clinical outcome of a burn. What factors affect that prediction can be investigated.

The sacroiliac joint (SIJ) has been implicated as a potential source of low back and buttock pain. Several types of motion palpation and pain provocation tests are used to evaluate SIJ dysfunction. The purpose of this study was to investigate the relationship between motion palpation and pain provocation tests in assessment of SIJ problems. This study is Descriptive Correlation. 50 patients between the ages of 20 and 65 participated. Four motion palpation tests (Sitting flexion, Standing flexion, Prone knee flexion, Gillet test) and three pain provocation tests (FABER, Posterior shear, Resisted abduction test) were examined. Chi-square analysis was used to assess the relationship between results of the individuals and composites of these two groups of tests. No significant relationship was found between these two groups of tests. It seems that motion palpation tests assess SIJ dysfunction and provocative tests assessed SIJ pain which do not appear to be related. Copyright © 2016 Elsevier Ltd. All rights reserved.

Staphylococcal scalded skin syndrome is an exfoliative skin disease. Reports of this syndrome in newborns caused by methicillin-resistant Staphylococcus aureus are rare but, when present, rapid diagnosis and treatment is required in order to decrease morbidity and mortality. A premature newly born girl weighing 1,520 g, born with a gestational age of 29 weeks and 4 days, developed staphylococcal scalded skin syndrome on the fifth day of life. Cultures on blood samples collected on the first and fourth days were negative, but Pseudomonas aeruginosa and Enterococcus sp. (vancomycin-sensitive) developed in blood cultures performed on the day of death (seventh day), and Pseudomonas aeruginosa and Serratia marcescens were identified in cultures on nasopharyngeal, buttock and abdominal secretions. In addition to these two Gram-negative bacilli, methicillin-resistant Staphylococcus aureus was isolated in a culture on the umbilical stump (seventh day). The diagnosis of staphylococcal scalded skin syndrome was based on clinical criteria.

Nerve compression injuries due to traumatic false aneurysm.

1984-01-01

Experience with 17 patients with delayed onset of compression neuropraxia due to hemorrhage following nonoperative treatment of penetrating arterial injuries is presented. Fifteen cases involved the arteries of the neck shoulder girdle and upper extremity and two the gluteal vessels. This resulted in dysfunction of components of the brachial plexus, median ulnar, and sciatic nerves. Follow-up extended from 3 to 18 months. Of 10 brachial plexus lesions two recovered fully, five partially, and three not at all. Of seven peripheral nerve injuries, full recovery occurred in two patients and none in five. Adverse prognostic factors for neurological recovery are sepsis, involvement of intrinsic hand innervation and the sciatic nerve. An improved prognosis may be expected for upper trunk lesions of the brachial plexus and radial nerve lesions. The complication is essentially avoidable and a careful appraisal of the circulatory status must be made in all patients with penetrating trauma in the neck and shoulder girdle and buttock.

A Review of Liposuction as a Cosmetic Surgical Procedure

PubMed Central

Sumrall, Arthur J.

1987-01-01

Liposuction (suction-assisted lipectomy) is today an accepted, closed surgical technique utilized by physicians practicing in a number of different specialties. It is a procedure that can be learned and used as an adjunct to a number of open procedures, including rhytidectomy and abdominoplasty. The two principal keys to successful liposuction procedures are: (1) good patient selection, and (2) realistic expectations. Good selection should be based on physiological skin age of the patient rather than chronological age. Many liposuction procedures can be performed under local anesthesia in an office surgical suite. A conservative approach is always appropriate, as overcorrection is difficult to treat. Areas that can be suctioned effectively include the face, chin, neck, anterior and posterior axilary areas, arms, breasts, abdomen, waist, hips, buttocks, thighs, knees, and ankles. Using the blunt cannula technique pioneered by Fischer and modified and popularized by Illouz and Fournier yields a high percentage of good results. A low percentage of possible complications and undesired sequelae have been documented. PMID:3323540

Is there a role for TENS application in the control of diabetes mellitus in insulin-dependent patients?

PubMed

Khan, Mueen Ullah

2012-11-01

An 80-year-old man with insulin-dependent diabetes mellitus presented to the hospital with low back pain. He was initially managed with non-steroidal anti-inflammatory drugs, tramadol and epidural steroid injection. Transcutaneous electrical nerve stimulation (TENS), applied on the back and buttocks, was subsequently advised. Initially, TENS was applied once every 24 hours. On improvement of pain symptoms, it was increased to thrice every 24 hours. The patient then complained of symptoms of hypoglycaemia (blood sugar level < 4 mmol/L). Discontinuation of TENS resulted in raised blood sugar level. When TENS was restarted, the same hypoglycaemic response was noted. The insulin dosage was adjusted to half of the patient's routine daily requirement with continued application of TENS. This incidental finding has alerted us to hypoglycaemic episodes following TENS application, which may be due to effective pain control, decreased sympathetic stimulation, enhanced insulin sensitivity or altered muscle metabolism due to electrical stimulation.

Tinea indecisiva is characterized by concentric scaly rings simulating tinea imbricata but caused by dermatophytes other than Trichophyton concentricum. Tinea indecisiva has been rarely reported. We report a unique case and review of the previously reported cases, pathogenesis, and management. An adult Indian man developed extensive tinea cruris and tinea corporis with concentric rings of scaly lesions over the groin, buttocks, and thighs following the use of oral corticosteroids and antifungal-steroid cream for 3 months. Mycologic and immunologic studies were performed for diagnosis. Diagnosis of tinea indecisiva was confirmed on the appearance of "ring-within-a-ring" lesions clinically and isolation of Trichophyton mentagrophytes var. interdigitale as the etiologic agent on mycologic testing. Intradermal testing with Trichophyton extract showed fluctuating hypersensitivity responses. Four-week treatment with daily oral terbinafine resulted in complete resolution. Tinea indecisiva should be considered in a patient with tinea imbricata-like lesions with local immunosuppression caused by a non-concentricum dermatophyte. © 2014 Canadian Dermatology Association.

Brainstem pontomedullary laceration (PML) in falls from a height appears as isolated cases and usually in feet-first impacts with a ring fracture. The aim of this study was to determine the frequency of PML in falls from a height, as well as the frequency of concomitant head and neck injuries. Out of 261 cases, PML was present in 40. An impact to the chin, as well as a feet- or buttocks-first impact, most often led to PML owing to transmission of the impact force. Also, a lateral, frontal, or posterior head impact, with subsequent hinge fracture, as well as the frontoposterior hyperextension of the head associated with an upper spine fracture, could be possible mechanisms of PML in falls from a height. The jawbone and other facial bones act as shock absorbers, and their fracture diminishes energy transfer toward the skull and protects the brain and brainstem from injury. © 2011 American Academy of Forensic Sciences.

Summary Introduction. Work-related Musculoskeletal Disorders (WMSDs) can impact on fatigue and productivity of office workers. This study aimed to investigate the effect of musculoskeletal problems on fatigue and productivity among office personnel. Methods. This study was performed on 101 Iranian office workers. Data were gathered through a demographic questionnaire, Nordic Musculoskeletal Questionnaire, Numeric Rating Scale, Persian version of Multidimensional Assessment of Fatigue Scale, and Persian version of Health and Work Questionnaire. Results. The results revealed that the highest prevalence rates of musculoskeletal symptoms in the past week were related to neck (41.6%), lower back (41.6%), and shoulders (40.6%). The mean score of discomfort/pain was 1.67, 1.55, and 1.31 in the neck, lower back, and shoulders, respectively. Additionally, the severity of discomfort/pain in neck, shoulders, lower back, and thighs was correlated to total fatigue. The severity of discomfort/pain in neck, lower back, buttock, and thighs was also correlated to the concentration/focus subscale of productivity. Conclusions. Improvement of working conditions is suggested to reduce musculoskeletal problems and fatigue and enhance productivity. PMID:29123372

This questionnaire-based study was aimed to measure the level of appreciation, awareness of the special tips, and practice patterns of monopolar radiofrequency among Korean dermatologists practicing a specific monopolar radiofrequency device (Thermage® Inc., Hayward, CA). A total of 82 surveys were analyzed to show that the majority of participants (78.8%) were highly satisfied with the outcomes of monopolar radiofrequency treatment. All respondents were aware of the Eye Tip 0.25 cm 2 , and the majority knew the difference between the Face tip (blue) and the Total tip (orange). Most (86.3%) agreed to the statement that 900 shots were appropriate for facial tightening in those between the ages of 35 and 65 years. 66.2% of participants reported to have perform monopolar radiofrequency to extra-facial sites within the past year. As for the tips, the Total tip was most popular for all body sties and the Big tip was favored for the abdomen, thighs and buttock. We hope our data allow dermatologists to better utilize monopolar radiofrequency. © 2017 Wiley Periodicals, Inc.

Lower-limb lymphedema is an incurable illness manifesting as visible swelling enlarging the leg(s) and/or feet, buttocks, and genitals. This study used semi-structured interviews and thematic analysis to explore sexual well-being among women with primary (congenital) lymphedema (n=11) or secondary lymphedema associated with gynecological cancer (n=8). Five themes (subthemes) summarized women's responses, with Attractiveness and Confidence (Publicly Unattractive, Privately Unconfident, Lymphedema or Aging?) describing women's central concern. These body image-related concerns accounted for sexual well-being in association with Partner Support (Availability of Support, Languages of Support, Fears About Support) and the degree of Functional Interruptions (Lymphedema in Context, Enduring Impacts, Overcoming Interruptions). Successful Lymphedema Coping (Control, Acceptance) and self-perceived ability to fulfill a valued Sexual Role also affected sexual well-being. Few differences between women with primary versus secondary lymphedema were evident. Lymphedema clinicians should screen for sexual concerns and have referral options available.

Caloric and exercise requirements of space flight - Biostereometric results from Skylab

NASA Technical Reports Server (NTRS)

Whittle, M. W.

1979-01-01

The biostereometric study of the Skylab astronauts used stereophotogrammetry to make accurate three-dimensional measurements of body form, from which regional and total body volumes were derived. Volume changes in the thighs and calves, over the course of the flight, showed a high correlation with inflight exercise on the bicycle ergometer, and suggested that an exercise level of 80-100 W-min/d/kg lean body mass would be necessary to prevent inflight muscle atrophy. The bicycle ergometer is thus a relatively inefficient means of preventing leg muscle atrophy. Inflight caloric intake showed a high correlation with the change in volume of the buttocks, the abdomen, and the body as a whole, and suggested that a caloric intake of 47-51 kcal/d/kg lean body mass would be necessary to prevent a change in body fat. Only one of the astronauts exceeded this range and gained body fat; the group as a whole showed a mean fat loss of 1.2 kg.

2006-04-01

The purpose of this study was to develop a simple, single-page measurement tool that evaluates risk of skin breakdown in the peadiatric population and apply it to the acutely hospitalized child. Data were collected over a 15-month period from 347 patients on four in-patient units (PICU, medical-surgical, oncology, and adolescents) on skin breakdown using the AHCPR staging guidelines and compared to the total score on the Starkid SkinScale in order to determine its ability to predict skin breakdown. The inter-rater reliability of the Starkid Skin Scale was r2 = 0.85 with an internal reliablity of 0.71. The sensitivity of the total score was low (17.5%) but highly specific (98.5%). The prevalence of skin breakdown in the acutely hospitalized child was 23%, the majority (77.5%) occurring as erythema of the skin. Buttocks, perineum, and occiput were the most common locations of breakdown. Occiput breakdown was more common in critically ill (PICU) patients while diaper dermatitis was more common in the general medical-surgical population.

Posterior intravaginal slingplasty (IVS) is a technique used for the treatment of apical prolapse. Type III meshes have been mostly used with this technique. In this article, a case of bilateral gluteo-vaginal sinus tract formation that complicated a posterior vaginal slingplasty with a type III mesh is presented. At 3 months follow-up, the patient complained for bulking through the vagina, continuous offensive vaginal discharge, and constant pain at the buttocks. She had prolapse recurrence, and there was defective healing at the gluteal entry points of the posterior IVS. Ten months after the initial surgery, she underwent a laparotomic subtotal hysterectomy and sacrocervicopexy with prolene type I mesh. At the same time, the posterior mesh was removed allowing the surgeon to discover communication of the canal of the mesh extending from gluteal incisions to the vagina epithelium. The sinus tract was managed surgically with excision of the surrounding tissues. There was no recurrence or other complications at 2 months follow-up.

Driver fatigue is an important contributor to road accidents. This paper reports a study that evaluated driver fatigue using multimodal fatigue measures, i.e., surface electromyography (sEMG), electroencephalography (EEG), seat interface pressure, blood pressure, heart rate and oxygen saturation level. Twenty male participants volunteered in this study by performing 60 min of driving on a static simulator. Results from sEMG showed significant physical fatigue (ρ < 0.05) in back and shoulder muscle groups. EEG showed significant (ρ < 0.05) increase of alpha and theta activities and a significant decrease of beta activity during monotonous driving. Results also showed significant change in bilateral pressure distribution on thigh and buttocks region during the study. These findings demonstrate the use of multimodal measures to assess early onset of fatigue. This will help us understand the influence of physical and mental fatigue on driver during monotonous driving. Copyright © 2014 Elsevier Ltd and The Ergonomics Society. All rights reserved.

First described in the past decade, schwannomatosis is a syndrome distinct from neurofibromatosis 2 (NF2). It is characterized by the development of multiple schwannomas, sparing the vestibular division of cranial nerve VIII, and may also predispose to develop meningiomas. We report two female patients, a 27 and a 44 years old who developed multiple peripheral schwannomas, but without involvement of the vestibular nerves, satisfying clinical criteria for schwannomatosis. Lack of vestibular nerve involvement was confirmed with MRI using an internal auditory canal protocol with 3 mm thick slices in both patients after age 30. Both patients developed a small neurofibroma in axillary subcutaneous tissues and a diffuse cutaneous neurofibroma of the left buttock, respectively. This report highlights that superficial neurofibromas may arise in the setting of schwannomatosis, which may have implications for the diagnostic criteria of this unique syndrome. In particular, the presence of a cutaneous neurofibroma in a patient with multiple schwannomas should not lead to a diagnosis of NF2.

Management of pilonidal sinus by Kshar Sutra, a minimally invasive treatment.

PubMed

Dwivedi, Amar P

2010-04-01

A Pilonidal sinus (PNS) occurs in the cleavage between the buttocks (natal cleft) and can cause discomfort, embarrassment and absence from work. It is more common in men (as they have more hair) than in women. The most commonly used surgical techniques for this disorder include excision and primary closure and excision with reconstructive flap. However, the risk of recurrence or of developing an infection of the wound after the operation is high. Also, the patient requires longer hospitalization, and the procedure is expensive. There is a similarity between Shalyaj Nadi Vran described in Sushruta Samhita and Pilonidal sinus. Sushruta has advocated a minimally invasive para-surgical treatment, viz., Kshar Sutra procedure, for nadi vran. Hence this therapy was tried in Pilonidal sinus, and is described in this case report. Kshar Sutra treatment not only minimizes complications and recurrence but also enables the patient to resume work quicker and with less discomfort, impact upon body image and self-esteem as well as reduced cost.

Few surveillance tools exist for monitoring tanning bed injuries. Twitter data were examined to identify and describe reports of tanning bed-caused burns. Tweets sent in 2013 containing keywords for tanning bed use and burning were content analyzed to determine whether a burn caused by a tanning bed was described, and additional data on tanning behavior and burn characteristics were extracted. After content assessment, 15,178 (64 %) tweets were found to describe a tanning bed-caused burn. Sites most reportedly burnt were buttocks (n = 3117), face/head (n = 1020), and chest/breast (n = 546). Alarmingly, 200 burns to the eyes/eyelids were mentioned. A total of 456 tweets described burning >1 time from a tanning bed. A total of 211 tweets mentioned falling asleep inside the tanning bed. In 2013, over 15,000 tweets reported tanning bed-caused burns. Twitter data provides unique insight into tanning behaviors and injuries not captured through traditional public health surveillance.

Fabry's disease is due to alpha-galactosidase deficiency. This rare lysosomal storage disease is transmitted by recessive X-linked heredity. Sphingolipids (galactosyl-glucosyl-ceramide) accumulate in many organs. A 19-year-old man with known hypoparathyroidism presented with telangiectasia and angiokeratomas on the buttocks, the hips, the hands and around the navel. For many years, he suffered from paroxysmal pain in the hands and feet. From childhood, he had complained of diffuse abdominal pain, associated with diarrhea. Ophthalmological slit lamp fundus examination showed corneal telangiectasia and cornea verticella. There was no kidney or heart involvement. The diagnosis of Fabry's disease was confirmed by very low levels of alpha-galactosidase. We did not find any other association of hypoparathyroidism and Fabry's disease in the literature. Hypoparathyroidism is not a manifestation of Fabry's disease. Idiopathic hypoparathyroidism is very rare and a genetic origin is known. This disease can be recessive X-linked. A co-transmission of idiopathic hypoparathyroidism and Fabry's disease is probable in our patient.

Paraparetic Guillain-Barré syndrome (GBS) is a rare subtype of GBS characterized by leg weakness and areflexia in the absence of neurological involvement of the arms, cranial nerves, or respiratory muscles. Onset is characterized by lower back, buttock, or leg pain, followed by development of symmetric flaccid limb weakness in the absence of sensory disturbance. We describe an elderly woman who developed postinfectious symmetric flaccid leg weakness in the absence of sensory disturbance. Serial nerve conduction studies were carried out over 5 months. Antecedent infection, a monophasic disease course, and the presence of cerebrospinal fluid albuminocytological dissociation suggested a diagnosis of paraparetic GBS. Serial nerve conduction studies demonstrated nondemyelinating reversible conduction failure, which was restricted to the legs. Axonal neuropathy was supported by the presence of anti-GM1 IgG antibodies. These findings suggest that patients with paraparetic GBS have axonal neuropathy, which is restricted to the lower limbs.

1996-01-01

Sixty patients (greater than 16 yrs old) suffering primary or relapse genital herpes simplex viruses (HSV) and relapse labial HSV were appointed for this study. Three or more relapses were experienced per year. Patients (under treatment) were divided into two groups (distribution areas), corresponding to either labial herpes or genital herpes. These groups were sub-divided into 3 groups. The total number of labial or facial HSV patients was 36 (10 in group 1, 12 in group 2, 14 in group 3) and 24 for genital, buttocks, or 'area pudenda' HSV patients (6 in group 1, 8 in group 2, 10 in group 3). The design was a randomized, double- blind study. The setting was hospital and outpatient. The patients diagnosed as having the HVS disease were sent to the dermatology department and were assigned to a group at random. Treatment was begun as follows: During the treatment signs and symptoms were assessed and after the treatment, the relapses were also assessed (biochemical and hematological tests before and after the treatment) and the diagnosis of the HSV type I and II. The statistical evaluation of the results was performed and carried out with the SPSS and BMDP program. The relapses of the herpes infection in the lips and the face were significantly reduced (p less than 0.026) in patients treated with laser He-Ne and laser He-Ne plus Acyclovir. The interim between the relapses also increased significantly (p less than 0.005) in relation with the group treated with Acyclovir. The duration of the herpetic eruptions was clearly reduced in all locations in patients treated with laser He-Ne plus Acyclovir. No differences were noted between patients treated with laser He-Ne only or Acyclovir only. Therefore it is probable that therapeutic synergism took place. In relation with this, laser He-Ne shows the same therapeutic efficacy as Acyclovir taken orally. The association of Acyclovir and laser Ne-Ne could be an alternative method for the treatment of HSV in the face. The number of relapses of the herpes infection in the genital, buttocks or 'area pudenda' and the interim between the relapses were not substantially modified with the treatment of laser He-Ne or laser Ne-Ne plus Acyclovir. Although a little difference exists in comparison with the patients treated with Acyclovir alone, a survey or an increased number of patients should be necessary.

Liposuction: more curettage than aspiration.

PubMed

Mottura, A A

1991-01-01

After infiltration with epinephrine solution in each adipose area, an 8- or 10-mm cannula, without the suction tube connected, was introduced. With a curettage maneuver and by directing the cannula upward, the fat began to come out spontaneously. After obtaining a considerable amount of fat, the suction tube was connected and the remaining fat tissue aspirated at low suction power (250 mm Hg). With this curettage maneuver adiposity of the abdomen, knees, and trochanteric areas can be reduced. However, in the back, buttocks, or thighs, where adiposity is more fibrous, aspiration is needed from the start in almost every case, but always at low-power suction. This procedure is indicated in particular for the face and neck and for secondary liposuction. The fact that fat comes out easily through the cannula (without suction) demonstrates that the curettage maneuver is more important than the aspiration. Only with curettage can a considerable amount of fat be removed. No fat is removed when aspiration of 1 atm without a curettage maneuver is used. Suction only helps to remove fat already mobilized and free in the cannula. Our experience includes 34 patients.

Optimal External Wrench Distribution During a Multi-Contact Sit-to-Stand Task.

2017-07-01

This paper aims at developing and evaluating a new practical method for the real-time estimate of joint torques and external wrenches during multi-contact sit-to-stand (STS) task using kinematics data only. The proposed method allows also identifying subject specific body inertial segment parameters that are required to perform inverse dynamics. The identification phase is performed using simple and repeatable motions. Thanks to an accurately identified model the estimate of the total external wrench can be used as an input to solve an under-determined multi-contact problem. It is solved using a constrained quadratic optimization process minimizing a hybrid human-like energetic criterion. The weights of this hybrid cost function are adjusted and a sensitivity analysis is performed in order to reproduce robustly human external wrench distribution. The results showed that the proposed method could successfully estimate the external wrenches under buttocks, feet, and hands during STS tasks (RMS error lower than 20 N and 6 N.m). The simplicity and generalization abilities of the proposed method allow paving the way of future diagnosis solutions and rehabilitation applications, including in-home use.

Piriformis muscle syndrome (PMS) is caused by prolonged or excessive contraction of the piriformis muscle associated with pain in the buttocks, hips, and lower limbs because of the close proximity to the sciatic nerve. Botulinum toxin type A (BoNT-A) reduces muscle hypertonia as well as muscle contracture and pain inhibiting substance P release and other inflammatory factors. BoNT-A injection technique is important considering the difficult access of the needle for deep location, the small size of the muscle, and the proximity to neurovascular structures. Ultrasound guidance is easy to use and painless and several studies describe its use during BoNT-A administration in PMS. In the present review article, we briefly updated current knowledge regarding the BoNT therapy of PMS, describing also a case report in which this syndrome was treated with an ultrasound-guided injection of incobotulinumtoxin A. Pain reduction with an increase of hip articular range of motion in this patient with PMS confirmed the effectiveness of BoNT-A injection for the management of this syndrome. PMID:26266421

Patients presenting with a penetrating missile lodged in the pelvis are at risk for having a urinary tract injury. Once in the bladder, the missile can become impacted in the urethra, causing retention that requires extraction. Rarely, the missile can be expulsed spontaneously through the urethra. To describe the world literature regarding undetected penetrating bladder injuries presenting as spontaneously voided bullets and to contribute an additional case to the literature. We present a case report of a 37-year-old man who sustained a gunshot wound to the right buttock, with an undetected urinary system injury and subsequent spontaneous voiding of a bullet. There have been <10 cases reported in the literature of spontaneously expulsed bullets from the urethra, all of which were undetected injuries on initial presentation. Physicians should be aware of the potential for undetected urinary tract injuries in patients with penetrating missiles to the pelvis and understand the appropriate evaluation and management strategies for these injuries.

2008-02-01

Community-acquired methicillin-resistant Staphylococcus aureus (CAMRSA) presents numerous diagnostic and therapeutic problems for the outpatient physician, including the appropriate use of antibiotics and proper counseling of families on ways to prevent household spread. Most cases of CAMRSA in children involve soft tissue and skin infection, which is precisely the type of infection most likely to be diagnosed in a dermatology practice. We reviewed 8 pediatric cases of cutaneous CAMRSA that presented over 8 months. The 8 pediatric patients presented with one or more of the following: folliculitis (n=4), abscesses of the groin (n=3), impetiginized atopic dermatitis (AD)(n=2), pustules (n=2), bullous impetigo (n= 1), and nonbullous impetigo (n=1). Three caregivers of these children developed abscesses in exposed areas such as the forearm (n=3) and calf (n=1). The folliculitis cases involved the abdomen, groin and diaper region, buttocks, and inner thighs; the impetiginized AD did not differ from the distribution of the AD. The variety of clinical presentations and the spread in households represent a few of the many facets of CAMRSA in the pediatric dermatology outpatient setting.

Leukocytoclastic vasculitis associated with clarithromycin.

Gavura, S R; Nusinowitz, S

1998-05-01

To report a possible case of leukocytoclastic vasculitis associated with clarithromycin therapy. An 83-year-old white woman was prescribed clarithromycin for pneumonia. Six days after her initial presentation, she developed lesions on her palms. Clarithromycin was discontinued at that time. The following day she developed purpuric eccymotic nonblanching lesions that primarily appeared on the lower extremities, buttocks, and abdomen. Colonoscopy revealed generalized erythema and edema of the bowel mucosa. Gastroscopy revealed duodenitis and gastritis, but no bleeding or ulceration. Skin biopsy of the lesions was compatible with leukocytoclastic vasculitis. Renal function was not affected, although hematuria was noted. All symptoms resolved after drug withdrawal and a short course of corticosteroids. Searches were performed on MEDLINE, Embase, International Pharmaceutical Abstracts, and major adverse drug reaction databases to identify reports and articles discussing clarithromycin- and macrolide-induced leukocytoclastic vasculitis. Leukocytoclastic vasculitis is one category of drug hypersensitivity reactions characterized by distinctive patterns of perivascular inflammation. The case described here is consistent with the diagnosis of leukocytoclastic vasculitis, and is similar to the other single published case report associated with clarithromycin. Leukocytoclastic vasculitis induced by clarithromycin is a rare but serious potential adverse effect.

To analyze a case series of patients who underwent injection of industrial liquid silicone in a clandestine manner and by unauthorized persons. We conducted a retrospective analysis of medical records of patients treated between September 2003 and December 2010. Data regarding gender, age, location and volume of silicone injected, time between application and clinical manifestations, complications, treatment and outcome were collected. Early manifestations were defined as occurring within 30 days of injection and late manifestations, the ones arising after this period. We treated 12 patients, eight were male, seven transsexuals. The volume injected ranged from 5 ml to 2000 ml, being unknown in three cases. The most often used injected sites were the thighs and buttocks. Eight patients had early manifestations, with inflammation and/or infection. Surgical debridement was necessary in five cases. Three patients with a history of injection in the breast region underwent adenomastectomy. There was one death due to refractory septic shock. The use of industrial liquid silicone should be completely contraindicated as a filling material and modification of body contouring, and may have serious complications, even death.

A 79-year-old woman was diagnosed with osteoarthritis of the left hip and scheduled for total hip arthroplasty. As two lesions were detected in branches of the coronary arteries, she was treated with catheter treatment. The patient was receiving anticoagulant treatment, which was suspended eight days before the operation; however, heparin was started at 6 days before the operation and was stopped 9 hours before the operation. On the 2nd postoperative day soon after transfer to the wheel chair, she was feeling unwell and was suffering from severe pain in her left buttock and left thigh. Her blood pressure had decreased to 70 mmHg. During abdominal contrast-enhanced CT, a hematoma was detected in the left iliopsoas muscle. Catheter therapy was started by the cardiovascular department and bleeding had stopped spontaneously. The patient was able to walk with a cane and was discharged on the 40th postoperative day. THA: total hip arthroplasty, CT: computed tomography, JOA score: Japanese Orthopaedic Association hip score, HA: hydroxyapatite, PMMA: polymethyl-methacrylate, APTT: activated partial thromboplastin time.

We report a fatal case of post-partum streptococcal toxic shock syndrome in a patient who was previously healthy and had presented to the emergency department with an extensive blistering ecchymotic lesions over her right buttock and thigh associated with severe pain. The pregnancy had been uncomplicated, and the mode of delivery had been spontaneous vaginal delivery with an episiotomy. She was found to have septicemic shock requiring high inotropic support. Subsequently, she was treated for necrotizing fasciitis, complicated by septicemic shock and multiple organ failures. A consensus was reached for extensive wound debridement to remove the source of infection; however, this approach was abandoned due to the patient's hemodynamic instability and the extremely high risks of surgery. Both the high vaginal swab and blister fluid culture revealed Group A beta hemolytic streptococcus infection. Intravenous carbapenem in combination with clindamycin was given. Other strategies attempted for streptococcal toxic removal included continuous veno-venous hemofiltration and administration of intravenous immunoglobulin. Unfortunately, the patient's condition worsened, and she succumbed to death on day 7 of hospitalization.

Introduction The purpose of this study is to report the findings resulting from chiropractic care using flexion distraction spinal manipulation for a patient with low back and radicular pain due to spinal stenosis caused by a synovial cyst. Case Report A 75-year-old man presented with low back pain radiating to the right anterior thigh and down the left posterior leg of 3 years' duration. Physical and imaging examinations showed a synovial cyst–induced spinal stenosis at the right L3-L4 level and bilateral L4-L5 spinal stenosis. Intervention and Outcomes Flexion distraction spinal manipulation and physiological therapeutics were applied at the levels of stenosis. After 4 visits, the patient noted total absence of the right and left lower extremity pain and no adverse reaction to treatment. After 3 months of treatment and 16 visits, his low back and buttock pain were minimal; and he had no leg pain. Conclusion Lumbar synovial cyst and stenosis–generated low back and radicular pain was 80% relieved in a 75-year-old man following Cox flexion distraction spinal manipulation. PMID:22942836

Pathology and clinical presentation of friction injuries: case series and literature review.

PubMed

Berke, Christine Thies

2015-01-01

Effective wound management is dependent, in part, on identification and correction of causative factors. Trunk wounds can be caused by pressure, shear, moisture, friction, or some combination of these factors. Wounds caused by moisture and/or friction are frequently mislabeled as pressure ulcers. This article presents a series of 45 patients who developed skin injuries on the medial buttocks and/or posterior thighs that the author believes were caused primarily by friction damage to the skin. The lesions were not located over palpable bony prominences and are therefore unlikely to be pressure ulcers. They were not located in skin folds and are unlikely to represent intertriginous dermatitis. Clinical data related to these 45 patients are presented, as are the location and characteristics of the lesions. These characteristics are discussed in relation to current literature regarding the pathology and clinical presentation of wounds caused by pressure, moisture, and friction. It is critical for wound clinicians and staff nurses to accurately identify the etiology of any wound. Wounds located on fleshy prominences exposed to repetitive friction should be labeled as friction injuries.

Autoimmune progesterone dermatitis: Case report with history of urticaria, petechiae and palpable pinpoint purpura triggered by medical abortion.

2016-03-17

Autoimmune progesterone dermatitis (APD) is a rare autoimmune response to raised endogenous progesterone levels that occur during the luteal phase of the menstrual cycle. Cutaneous, mucosal lesions and other systemic manifestations develop cyclically during the luteal phase of the menstrual cycle when progesterone levels are elevated. APD symptoms usually start 3 - 10 days before menstruation and resolve 1 - 2 days after menstruation ceases. A 30-year-old woman presented with urticaria, petechiae and palpable pinpoint purpura lesions of the legs, forearms, neck and buttocks 1 week prior to her menses starting and 2 months after a medical abortion. She was diagnosed with allergic contact dermatitis and topical steroids were prescribed. Her skin conditions did not improve and were associated with her menstrual cycle. We performed an intradermal test using progesterone, which was positive. She was treated with oral contraceptive pills and the symptoms were resolved. This is a typical case of APD triggered by increased sensitivity to endogenous progesterone induced a few months after medical abortion.

Preferences for body type and body characteristics associated with attractive and unattractive bodies: Jackson and McGill revisited.

The present investigation replicates Jackson and McGill's study (1996) and extends it by considering the effects of respondents' own height, weight, and body mass on perceptions of attractiveness. Results, although generally supportive of those found by Jackson and McGill, point to the influence of respondents' own physical characteristics in the process of perceptions of attractiveness: only 1 of Jackson and McGill's 3 (of a possible 19) differences between responses of African- and Euro-American women was corroborated (the importance of silky hair for Euro-American women), whereas a second difference (the importance of round buttocks for African-American women) disappeared when controlling for respondents' weight, height, and body mass. Although differences between the two investigations may be attributed to regional differences in the surveyed students (Michigan and North Carolina), the small effect of one's own weight, height, and body mass in assessing an other-sex person's attractiveness may reflect adherence to norms learned very early in life that are subject to regional variations.

Findings conflict as to whether thin-ideal media affect women's body satisfaction. Meta-analyses of experimental studies reveal small or null effects, but many women endorse appearance-related media pressure in surveys. Using a novel approach, two samples of women (Ns=656, 770) were exposed to bikini models, fashion models, or control conditions and reported the effects of the images their body image. Many women reported the fashion/bikini models made them feel worse about their stomachs (57%, 64%), weight (50%, 56%), waist (50%, 56%), overall appearance (50%, 56%), muscle tone (46%, 52%), legs (45%, 48%), thighs (40%, 49%), buttocks (40%, 43%), and hips (40%, 46%). In contrast, few women (1-6%) reported negative effects of control images. In open-ended responses, approximately one-third of women explicitly described negative media effects on their body image. Findings revealed that many women perceive negative effects of thin-ideal media in the immediate aftermath of exposures in experimental settings. Copyright © 2017 Elsevier Ltd. All rights reserved.

Human enterovirus (EV) infection causes hand, foot, and mouth disease (HFMD) and herpangina (HA). We studied the prevalence of enterovirus (EV) among patients with HFMD and HA in Thailand during 2013. We conducted a study in archived specimens of patients sent for screening for enterovirus. A total of 203 clinical specimens from 184 individuals with painful blister in the oropharynx and on the palms, soles, knees, elbows or buttock were examined by semi-nested polymerase chain reaction (PCR) for the 5'UTR and VP1 genes of EV. Eighty-six samples were positive: EV71 was detected in 14 (30%), CV-A8 in 12 (26%) and CV-A16 in 10 (21%). Classification of EV species detected revealed that 46 specimens were EV-A, 14 specimens were EV-B, 1 specimen was EV-D, and 16 specimens were positive for unclassified enterovirus. The majority of individuals with EV infection were aged 2-6 years. Multiple EV-A serotypes were detected among HFMD and HA patients in our study.

Sacroiliac joint tuberculosis

2006-01-01

Infections of the sacroiliac joint are uncommon and the diagnosis is usually delayed. In a retrospective study, 17 patients who had been treated for tuberculosis sacroiliitis between 1994 and 2004 were reviewed. Two patients were excluded due to a short follow-up (less than 2 years). Low back pain and difficulty in walking were the most common presenting features. Two patients presented with a buttock abscess and spondylitis of the lumbar spine was noted in two patients. The Gaenslen’s and FABER (flexion, abduction and external rotation) tests were positive in all patients. Radiological changes included loss of cortical margins with erosion of the joints. An open biopsy and curettage was performed in all patients; histology revealed chronic infection and acid-fast bacilli were isolated in nine patients. Antituberculous (TB) medication was administered for 18 months and the follow-up ranged from 3 to 10 years (mean: 5 years). The sacroiliac joint fused spontaneously within 2 years. Although all patients had mild discomfort in the lower back following treatment they had no difficulty in walking. Sacroiliac joint infection must be included in the differential diagnosis of lower back pain and meticulous history and clinical evaluation of the joint are essential. PMID:16673102

Deep gluteal space problems: piriformis syndrome, ischiofemoral impingement and sciatic nerve release.

Deep gluteal syndrome (DGS) is an underdiagnosed entity characterized by pain and/or dysesthesias in the buttock area, hip or posterior thigh and/or radicular pain due to a non-discogenic sciatic nerve entrapment in the subgluteal space. Multiple pathologies have been incorporated in this all-included "piriformis syndrome", a term that has nothing to do with the presence of fibrous bands, obturator internus/gemellus syndrome, quadratus femoris/ischiofemoral pathology, hamstring conditions, gluteal disorders and orthopedic causes. This article describes the subgluteal space anatomy, reviews known and new etiologies of DGS, and assesses the role of the radiologist and orthopaedic surgeons in the diagnosis, treatment and postoperative evaluation of sciatic nerve entrapments. DGS is an under-recognized and multifactorial pathology. The development of periarticular hip endoscopy has led to an understanding of the pathophysiological mechanisms underlying piriformis syndrome, which has supported its further classification. The whole sciatic nerve trajectory in the deep gluteal space can be addressed by an endoscopic surgical technique. Endoscopic decompression of the sciatic nerve appears useful in improving function and diminishing hip pain in sciatic nerve entrapments, but requires significant experience and familiarity with the gross and endoscopic anatomy.

INTRODUCTION Gluteal artery pseudoaneurysms are rare, yet the most common in cases involving the superior gluteal artery. Pseudoaneurysms of the inferior gluteal artery are uncommon and are often related to blunt or penetrating trauma, infections and fractures of the pelvis. PRESENTATION OF CASE The authors present a case of pseudoaneurysm of the inferior gluteal artery related to an iatrogenic injury due to intramuscular injection of medication, which was treated with selective embolization of the artery during angiography. DISCUSSION The most common manifestation of an inferior gluteal artery pseudoaneurysm is the presence of a painful mass in the buttock that may or may not be associated with neurological symptoms due to compression of the sciatic nerve. Ultrasound with color Doppler and computerized tomography with multi-detectors are useful non-invasive tools for diagnosis. However, both diagnosis and therapy are facilitated by catheter angiography. CONCLUSION This case cautions that although pseudoaneurysms are rare, pseudoaneurysms of the inferior gluteal artery require a high index of suspicion and careful physical examination by the physician in order to avoid misdiagnosis. It also illustrates the usefulness of a minimally invasive modality for treatment of these lesions. PMID:25506847

Tumoral calcinosis is a rare benign disease, defined by the presence of calcified deposits in periarticular tissues. It can be hereditary or secondary at chronic renal failure at the stage of dialysis. This work illustrates the contribution of single-photon emission computed tomography (SPECT/CT) in the diagnosis and management of tumoral calcinoses in a chronic hemodialysis patient, based on a clinical case. A 62-year-old patient, chronic hemodialysis since 24 years, presented a mechanical pain shoulders, knees and hips with limitation of joint mobility. The clinical exam found a mass of soft tissue in the buttocks. The radiological exam showed the presence of periarticular calcifications with no bone involvement. The SPECT/CT revealed a multifocal tumoral calcinosis affecting shoulders, elbows, wrists, hips and knees, associated with alveolar and abdominal calcinosis. Tumoral calcinosis is a distinct clinicopathological entity characterised by periarticular soft tissue calcium deposits. The SPECT/CT is important in the diagnosis, the assessment of extension and monitoring of tumoral calcinosis after treatment.

Histologic studies have become increasingly important in recognizing morphologic differences in photoaged versus intrinsically aged skin. Earlier histologic studies have attempted to evaluate these changes by examining anatomical sites which are not comparable, such as face and buttocks. As part of a multicenter study, we have quantitatively examined a panel of 16 histologic features in baseline facial skin biopsies from 158 women with moderate to severe photodamage. When compared to the postauricular area (photo protected), biopsies of the crow's feet area (photo exposed) had a twofold increase in melanocytes and a statistically significant increase in melanocytic atypia (p < .0001) and epidermal melanin (p < .0001). Other epidermal changes included reduced epidermal thickness (p < .01), more compact stratum corneum (p < .0001) and increased granular layer thickness (p < .0001) in the crow's feet skin. There was increased solar elastosis (p < .0001), dermal elastic tissue (p < .0001), melanophages (p < .0001), perivascular inflammation (p < .05) and perifollicular fibrosis (p < .01) but no change in the number of mast cells or dermal mucin in the photo exposed skin. Our data document quantitative differences in photoaged versus intrinsically aged facial skin and provides the groundwork for future studies to evaluate the efficacy of new treatments for photoaged skin.

This paper deals with the flow dynamics around a competitive swimmer during underwater glide phases occurring at the start and at every turn. The influence of the head position, namely lifted up, aligned and lowered, on the wall shear stress and the static pressure distributions is analyzed. The problem is considered as 3D and in steady hydrodynamic state. Three velocities (1.4 m/s, 2.2 m/s and 3.1 m/s) that correspond to inter-regional, national and international swimming levels are studied. The flow around the swimmer is assumed turbulent. The Reynolds-averaged Navier-Stokes (RANS) equations are solved with the standard k-ω turbulent model by using the CFD (computational fluid dynamics) numerical method based on a volume control approach. Numerical simulations are carried out with the ANSYS FLUENT® CFD code. The results show that the wall shear stress increases with the velocity and consequently the drag force opposing the movement of the swimmer increases as well. Also, high wall shear stresses are observed in the areas where the body shape, globally rigid in form, presents complex surface geometries such as the head, shoulders, buttocks, heel and chest.

First case of symmetric drug-related intertriginous and flexural exanthema (sdrife) due to rivastigmine?

The term 'baboon syndrome' was introduced in 1984 to describe a special form of systemic, contact-type dermatitis that occurs after ingestion or systemic absorption of a contact allergen in individuals previously sensitized by topical exposure to the same allergen in the same areas. Its clinical picture presents as an erythema of the buttocks and upper inner thighs resembling the red bottom of baboons. This reaction was originally observed with mercury, nickel, and ampicillin. In 2004, some authors proposed the acronym SDRIFE standing for 'symmetric drug-related intertriginous and flexural exanthema' specifically for cases elicited by systemically administered drugs. Since 1984, about 100 cases have been reported in the literature; for most of the concerned drugs, previous skin sensitization or possible cross-sensitization has not been shown. We report the first case of SDRIFE due to rivastigmine, with the exception of an erythematous maculopapular eruption due to rivastigmine that was previously reported. Rivastigmine is a reversible and noncompetitive acetylcholinesterase inhibitor used for the treatment of Alzheimer disease. SDRIFE is an important condition to keep in mind in order to avoid a misdiagnosis when dealing with other exanthematous disorders and to prevent re-exposure to the responsible allergen in the future.

Symmetrical Drug-related Intertriginous and Flexural Exanthema Induced by Doxycycline

Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is a cutaneous drug reaction characterized by erythema over the buttocks, thighs, groin, and flexural regions most commonly associated with the use of beta-lactam antibiotics. Although the exact pathophysiology of this disease remains unknown, it is theorized to be the result of a delayed hypersensitivity response presenting as a cutaneous eruption days to weeks after exposure to the drug. The treatment involves discontinuation of the suspected medication, symptomatic control of pruritus, and topical steroid therapy. A 51-year-old woman with homocystinuria and fibromyalgia was admitted with fevers, pancytopenia (later diagnosed to be acute myelogenous leukemia), and a targetoid cutaneous eruption in the setting of a recent tick bite. She was subsequently noted to have symmetric, pruritic, erythematous papules over the lateral neck, retroauricular regions, lateral aspects of the inframammary regions, medial upper arms, axillae, and the lower abdomen two weeks after starting doxycycline. Considering the morphology, distribution, and intense pruritis associated with the eruption, a diagnosis of SDRIFE was made. Doxycycline discontinuation along with topical steroid therapy resulted in the resolution of the eruption and pruritus. Given the widespread use of doxycycline, clinicians should be aware of this possible side effect. PMID:29340257

To discuss the clinical and pathological features, differential diagnosis and prognosis of fibrous hamartoma of infancy (FHI), seventeen FHI specimens were analyzed with H&E staining and strepavidin peroxidase (SP) immunohistochemistry to detect distinguishing tissue markers. The long-term outcomes of select cases were also obtained. Among the 17 patients (13 males, 4 females, average age 16 months), FHI manifested as a subcutaneous painless mass, primarily on the back of the neck, the upper arms and buttocks. One recurrence was noted among six follow-up cases. The tumors consisted of three main components: fibrous connective tissue; mature fat; and undifferentiated mesenchymal tissue. Immunohistochemistry revealed that fibrous connective tissue was positive for SMA and actin, mature fat tissue was positive for S-100 protein, and undifferentiated mesenchymal tissue was positive for CD34 and was partially positive for actin and SMA. The tumors were negative for desmin, NSE, bcl-2, β-catenin and Ki-67. In brief, FHI is a benign, fibroblastic/myofibroblastic proliferative lesion. Defined histologic features of FHI as presented here would distinguish FHI from similar invasive tumors including infant fibromatosis, calcifying aponeurotic fibroma, fibrous fatty tumor and embryonal rhabdomyosarcoma. Once clearly identified, FHI is curable with complete resection. PMID:26045872

Gluteal Compartment Syndrome following an Iliac Bone Marrow Aspiration

Vega-Najera, Carlos; Leal-Contreras, Carlos; Leal-Berumen, Irene

2013-01-01

The compartment syndrome is a condition characterized by a raised hydraulic pressure within a closed and non expandable anatomical space. It leads to a vascular insufficiency that becomes critical once the vascular flow cannot return the fluids back to the venous system. This causes a potential irreversible damage of the contents of the compartment, especially within the muscle tissues. Gluteal compartment syndrome (GCS) secondary to hematomas is seldom reported. Here we present a case of a 51-year-old patient with history of a non-Hodgkin lymphoma who underwent a bone marrow aspiration from the posterior iliac crest that had excessive bleeding at the puncture zone. The patient complained of increasing pain, tenderness, and buttock swelling. Intraoperative pressure validation of the gluteal compartment was performed, and a GCS was diagnosed. The patient was treated with a gluteal region fasciotomy. The patient recovered from pain and swelling and was discharged shortly after from the hospital. We believe clotting and hematologic disorders are a primary risk factor in patients who require bone marrow aspirations or biopsies. It is important to improve awareness of GCS in order to achieve early diagnosis, avoid complications, and have a better prognosis. PMID:24392235

To elucidate the genes responsible for constitutive human skin color, we measured the extent of skin pigmentation in the buttock, representative of lifelong non-sun-exposed skin, and conducted a gene mapping study on skin color in an isolated Mongolian population composed of 344 individuals from 59 families who lived in Dashbalbar, Mongolia. The heritability of constitutive skin color was 0.82, indicating significant genetic association on this trait. Through the linkage analysis using 1,039 short tandem repeat (STR) microsatellite markers, we identified a novel genomic region regulating constitutive skin color on 11q24.2 with an logarithm of odds (LOD) score of 3.39. In addition, we also found other candidate regions on 17q23.2, 6q25.1, and 13q33.2 (LOD ≥ 2). Family-based association tests on these regions with suggestive linkage peaks revealed ten and two significant single nucleotide polymorphisms (SNPs) on the linkage regions of chromosome 11 and 17, respectively. We were able to discover four possible candidate genes that would be implicated to regulate human skin color: ETS1, UBASH3B, ASAM, and CLTC.

Identifying an eschar in scrub typhus is useful for initiation of prompt and appropriate antibiotic therapy. The distribution of eschars in all children <15 years of age admitted with confirmed scrub typhus over a 5 year period is described. Of 431 children admitted with scrub typhus, eschars were present in 176 (40.8%) children with the following distribution: head, face and neck, 33 (19.1%); axillae, 37 (21%); chest and abdomen, 21 (11.9%); genitalia, inguinal region and buttocks, 58 (33%); back, 8 (4.5%); upper extremities, 13 (7.4%); and lower extremities, 5 (2.8%). The commonest sites of eschars were scrotum (27 of 106; 25.5%) and axillae (15 of 106; 14.2%) in males and axillae (22 of 70; 31.4%) and groin (16 of 70; 22.9%) in females. Eschars were seen within skin folds in 100 of 176 (56.8%) children. Children should be carefully examined for the presence of eschar especially in the skin folds of the genitalia, axillae and groin to make an early diagnosis of scrub typhus. © The Author [2016].

Genital Herpes: A Review.

PubMed

Groves, Mary Jo

2016-06-01

Genital herpes is a common sexually transmitted disease, affecting more than 400 million persons worldwide. It is caused by herpes simplex virus (HSV) and characterized by lifelong infection and periodic reactivation. A visible outbreak consists of single or clustered vesicles on the genitalia, perineum, buttocks, upper thighs, or perianal areas that ulcerate before resolving. Symptoms of primary infection may include malaise, fever, or localized adenopathy. Subsequent outbreaks, caused by reactivation of latent virus, are usually milder. Asymptomatic shedding of transmissible virus is common. Although HSV-1 and HSV-2 are indistinguishable visually, they exhibit differences in behavior that may affect management. Patients with HSV-2 have a higher risk of acquiring human immunodeficiency virus (HIV) infection. Polymerase chain reaction assay is the preferred method of confirming HSV infection in patients with active lesions. Treatment of primary and subsequent outbreaks with nucleoside analogues is well tolerated and reduces duration, severity, and frequency of recurrences. In patients with HSV who are HIV-negative, treatment reduces transmission of HSV to uninfected partners. During pregnancy, antiviral prophylaxis with acyclovir is recommended from 36 weeks of gestation until delivery in women with a history of genital herpes. Elective cesarean delivery should be performed in laboring patients with active lesions to reduce the risk of neonatal herpes.

Hand, foot and mouth disease (HFMD): emerging epidemiology and the need for a vaccine strategy.

PubMed

2016-10-01

Hand, foot, and mouth disease (HFMD) is a contagious viral disease and mainly affects infants and young children. The main manifestations are fever, vesicular rashes on hand, feet and buttocks and ulcers in the oral mucosa. Usually, HFMD is self-limiting, but a small proportion of children may experience severe complications such as meningitis, encephalitis, acute flaccid paralysis and neurorespiratory syndrome. Historically, outbreaks of HFMD were mainly caused by two enteroviruses: the coxsackievirus A16 (CV-A16) and the enterovirus 71 (EV-A71). In the recent years, coxsackievirus A6 and coxsackievirus A10 have been widely associated with both sporadic cases and outbreaks of HFMD worldwide, particularly in India, South East Asia and Europe with an increased frequency of neurological complications as well as mortality. Currently, there is no pharmacological intervention or vaccine available for HFMD. A formalin-inactivated EV-A71 vaccine has completed clinical trial in several Asian countries. However, this vaccine cannot protect against other major emerging etiologies of HFMD such as CV-A16, CV-A6 and CV-A10. Therefore, the development of a globally representative multivalent HFMD vaccine could be the best strategy.

An ability to reliably assess excess skin after massive weight loss using well-described and transferrable methods is important. The aim of this trial was to evaluate inter-rater reliability of ptosis and circumference measurements in patients with excess skin after bariatric surgery. Twenty-five postbariatric patients were included in the study, and their excess skin was measured 18 months after surgery. A protocol was designed to measure excess skin in a standardised way. To evaluate the inter-rater reliability in the measuring protocol, all patients were measured twice, by a specialist nurse and a specialist physiotherapist. All circumference measurements on different body parts had an ICC > 0.9, indicating high reliability. Furthermore, all breast and abdominal ptosis measurements had high reliability. In contrast, visual evaluation of abdominal ptosis had poor reliability. Measurements of ptoses on different body parts had an ICC > 0.6. There were no systematic differences between the results of the two testers, except for measurements of the buttocks and maximal knee circumference. The measuring protocol presented in this study has high reliability and, therefore, represents a useful instrument to provide a consistent and objective assessment of excess skin in the postbariatric patient.

Role of fibroblast-derived factors in the pathogenesis of melasma.

The hyperactive melanocytes present in melasma skin are confined to the epidermis, but epidermal ablation to treat melasma pigmentation may lead to disease recurrence and aggravation. Melanocyte function is regulated by interactions between melanocytes and neighbouring cells such as keratinocytes and fibroblasts. Because melasma skin usually shows dermal changes after exposure to sunlight, we hypothesized that sun-damaged fibroblasts might play a crucial role in the pathogenesis of melasma. In this study, the melanogenic role of primary cultured fibroblasts from human melasma skin was investigated. We explored whether primary cultured fibroblasts from melasma tissue have a melanogenic function on cultured human epidermal melanocytes and artificial skin. The cytokine profile derived from fibroblasts and their effect on the pigmented epidermal equivalents were investigated. Fibroblasts from the melasma lesion and perilesional skin increased melanogenesis in cultured human epidermal melanocytes and in artificial skin. Fibroblasts from the melasma lesion and perilesional skin secreted more nerve growth factor (NGF)-β than those in normal buttock skin, and also increased melanogenesis and the expression level of NGF-β in cultured human epidermal melanocytes and artificial skin. These results suggest that fibroblasts may play a role in melanogenesis and the pathogenesis of melasma. © 2016 British Association of Dermatologists.

Factors Influencing Relapse-Free Survival in Merkel Cell Carcinoma of the Lower Limb-A Review of 60 Cases

Purpose: Factors affecting relapse-free survival (RFS) in patients with Merkel cell carcinoma (MCC) of the lower limb were reviewed. Methods and Materials: The records of 60 patients from 1986 to 2005 with a diagnosis of MCC of the lower limb or buttock were retrospectively reviewed. The patients were treated with curative intent with surgery, radiation, or chemotherapy. Results: The 5-year overall survival, disease-specific survival, and RFS were 53%, 61%, and 20%, respectively. Factors influencing RFS were analyzed using univariate analysis. It appeared that recurrent disease worsened RFS (p = 0.03) and the addition of any radiotherapy improved RFS (p <0.001),more » as did radiotherapy to the inguinal nodes (p = 0.01) or primary site and inguinal nodes (p = 0.003). Age, surgical margins, and stage were not statistically significant. On multivariate analysis, the only significant factor was the addition of radiotherapy (hazard ratio = 0.51 p = 0.03). Conclusion: The addition of radiotherapy improves RFS compared with surgery alone. Elective treatment should be given to the inguinal nodes to reduce the risk of relapse.« less

Biomechanics Analysis of Pressure Ulcer Using Damaged Interface Model between Bone and Muscle in the Human Buttock

NASA Astrophysics Data System (ADS)

Slamet, Samuel Susanto; Takano, Naoki; Tanabe, Yoshiyuki; Hatano, Asako; Nagasao, Tomohisa

This paper aims at building up a computational procedure to study the bio-mechanism of pressure ulcer using the finite element method. Pressure ulcer is a disease that occurs in the human body after 2 hours of continuous external force. In the very early stage of pressure ulcer, it is found that the tissues inside the body are damaged, even though skin surface looks normal. This study assumes that tension and/or shear strain will cause damage to loose fibril tissue between the bone and muscle and that propagation of damaged area will lead to fatal stage. Analysis was performed using the finite element method by modeling the damaged fibril tissue as a cutout. By varying the loading directions and watching both tensile and shear strains, the risk of fibril tissue damage and propagation of the damaged area is discussed, which may give new insight for the careful nursing for patients, particularly after surgical treatment. It was found that the pressure ulcer could reoccur for a surgical flap treatment. The bone cut and surgical flap surgery is not perfect to prevent the bone-muscle interfacial damage.

This paper introduces the recently developed TexiCare device that aims at preventing pressure ulcers for people with spinal cord injury. This embedded device is aimed to be mounted on the user wheelchair. Its sensor is 100% textile and allows the measurement of pressures at the interface between the cushion and the buttocks. It is comfortable, washable and low cost. It is connected to a cigarette-box sized unit that (i) measures the pressures in real time, (ii) estimates the risk for internal over-strains, and (iii) alerts the wheelchair user whenever necessary. The alert method has been defined as a result of a utility/usability/acceptability study conducted with representative end users. It is based on a tactile-visual feedback (via a watch or a smartphone for example): the tactile modality is used to discreetly alarm the person while the visual modality conveys an informative message. In order to evaluate the usability of the TexiCare device, a paraplegic volunteer equipped his wheelchair at home during a six months period. Interestingly, the first results revealed bad habits such as an inadequate posture when watching TV, rare relief maneuvers, and the occurrence of abnormal high pressures.

Non-Traumatic Myositis Ossificans in the Lumbosacral Paravertebral Muscle

PubMed Central

Jung, DaeYoung; Roh, Ji Hyeon

2013-01-01

Myositis ossificans (MO) is a benign condition of non-neoplastic heterotopic bone formation in the muscle or soft tissue. Trauma plays a role in the development of MO, thus, non-traumatic MO is very rare. Although MO may occur anywhere in the body, it is rarely seen in the lumbosacral paravertebral muscle (PVM). Herein, we report a case of non-traumatic MO in the lumbosacral PVM. A 42-year-old man with no history of trauma was referred to our hospital for pain in the low back, left buttock, and left thigh. On physical examination, a slightly tender, hard, and fixed mass was palpated in the left lumbosacral PVM. Computed tomography showed a calcified mass within the left lumbosacral PVM. Magnetic resonance imaging (MRI) showed heterogeneous high signal intensity in T1- and T2-weighted image, and no enhancement of the mass was found in the postcontrast T1-weighted MRI. The lack of typical imaging features required an open biopsy, and MO was confirmed. MO should be considered in the differential diagnosis when the imaging findings show a mass involving PVM. When it is difficult to distinguish MO from soft tissue or bone malignancy by radiology, it is necessary to perform a biopsy to confirm the diagnosis. PMID:23908707

Summary Background Deep gluteal syndrome (DGS) is an underdiagnosed entity characterized by pain and/or dysesthesias in the buttock area, hip or posterior thigh and/or radicular pain due to a non-discogenic sciatic nerve entrapment in the subgluteal space. Multiple pathologies have been incorporated in this all-included “piriformis syndrome”, a term that has nothing to do with the presence of fibrous bands, obturator internus/gemellus syndrome, quadratus femoris/ischiofemoral pathology, hamstring conditions, gluteal disorders and orthopedic causes. Methods This article describes the subgluteal space anatomy, reviews known and new etiologies of DGS, and assesses the role of the radiologist and orthopaedic surgeons in the diagnosis, treatment and postoperative evaluation of sciatic nerve entrapments. Conclusion DGS is an under-recognized and multifactorial pathology. The development of periarticular hip endoscopy has led to an understanding of the pathophysiological mechanisms underlying piriformis syndrome, which has supported its further classification. The whole sciatic nerve trajectory in the deep gluteal space can be addressed by an endoscopic surgical technique. Endoscopic decompression of the sciatic nerve appears useful in improving function and diminishing hip pain in sciatic nerve entrapments, but requires significant experience and familiarity with the gross and endoscopic anatomy. Level of evidence IV. PMID:28066745

Introduction Lipoma is the most frequent benign tumor of the soft tissue. This lesion is often asymptomatic except in cases of enormous masses compressing nervous-vascular structures. Although the diagnosis is mostly clinical, imaging tools are useful to confirm the adipose nature of the lesion and to define its anatomic border. Sometimes, lipomas may be the result of a previous trauma, such as in this patient. Case presentation A 45-year-old man presented at our institution with a giant hard firm mass in the upper external quadrant of the right buttock disclosed after a weight loss diet. Subsequent magnetic resonance imaging showed a giant adipose mass developed beneath the large gluteal muscle and among the fibers of the medium and small gluteal muscles. When questioned on his medical history, the patient reported a blunt trauma of the lower back 14 years earlier. He underwent surgery and histological examination confirmed a giant lipoma. Conclusion Lipomas might result from a previous trauma. It is hypothesized that the trigger mechanism is activated by cytokine and growth factors released after the trauma. We herein present an exceptional case of a giant post-traumatic lipoma which caused a painful compression on the right sciatic nerve. PMID:18826615

Ethnic and racial differences in infant skin have not been well characterized. The purpose of this study was to establish whether there are ethnic differences and similarities in the stratum corneum (SC) functions of Thai and Chinese infants. Healthy infants 6 to 24 months of age (N = 60; 30 Thai, 30 Chinese) who resided in Bangkok, Thailand, were enrolled. Transepidermal water loss (TEWL) and SC hydration (capacitance) on the thigh, buttock, and upper arm were measured. Ceramide content was determined in the SC on the upper arm. SC hydration was not remarkably different between the two ethnicities at any site measured, but TEWL was significantly higher in Chinese infants than in Thai infants at all sites. Hydration of the SC was not significantly correlated with age in either ethnicity. TEWL had significant but weak correlations with age on the thigh and upper arm in Thai infants. Ceramide content was significantly higher in Chinese SC than in Thai SC. No relationship between ceramide content and TEWL or hydration was observed in either ethnicity. The significant differences in TEWL and ceramide contents between Chinese and Thai infant skin could prove useful in designing skin care and diapering products that are best suited for each ethnicity. © 2017 Wiley Periodicals, Inc.

Hamstring injuries are frequent injuries in athletes, with the most common being strains at the musculotendinous junction or within the muscle belly. Conversely, hamstring avulsions are rare and often misdiagnosed leading to delay in appropriate surgical interventions. The purpose of this case report is to describe the history and physical examination findings that led to appropriate diagnostic imaging and the subsequent diagnosis and expedited surgical intervention of a complete avulsion of the hamstring muscle group from the ischium in a military combatives athlete. The patient was a 25 year-old male who sustained a hyperflexion injury to his right hip with knee extension while participating in military combatives, presenting with acute posterior thigh and buttock pain. History and physical examination findings from a physical therapy evaluation prompted an urgent magnetic resonance imaging (MRI) study, which led to the diagnosis of a complete avulsion of the hamstring muscle group off the ischium. Expedited surgical intervention occurred within 13 days of the injury potentially limiting comorbidities associated with delayed diagnosis. Recognition of the avulsion led to prompt surgical evaluation and intervention. Literature has shown that diagnosis of hamstring avulsions are frequently missed or delayed, which results in a myriad of complications. Level 4.

A 5-year-old boy presented with worsening headaches for 3 months. On examination, he was found to have a hairless fatty tissue nevus of the scalp (nevus psiloliparus), subcutaneous soft tissue masses on the right side of his face, neck, mandible and right buttock and epibulbar dermoid of the right eye (choristoma) (Figs. 1A, B). Magnetic resonance imaging revealed a large suprasellar mass, which was debulked and found to be a pilocytic astrocytoma. Testing was not performed for the BRAF/KIAA1549 fusion or BRAFV600E mutation. Seven years later, he was started on adjuvant chemotherapy for gradual tumor progression. Over the ensuing 3 years, he had further disease progression despite treatment with 3 frontline chemotherapy regimens: vinblastine, carboplatin/vincristine, and irinotecan/bevacizumab. Targeted sequencing of tissue from the right gluteal mass, revealed a mosaic activating FGFR1 c.1966A>G (p.Lys656Glu) mutation, absent in normal left gluteal tissue, confirming the diagnosis of encephalocraniocutaneous lipomatosis (ECCL), belonging to the family of RASopathies (including neurofibromatosis type I, Noonan syndrome, Costello syndrome), with constitutive activation of the mitogen-activated protein kinase (MAPK) pathway, and an increased risk of developing neoplasms. He was started on trametinib, a MEK inhibitor, off-label, targeting the MAPK pathway downstream from FGFR1, with stable tumor size at last follow-up, after 6 months on therapy.

Postirradiation sarcomas are an unusual but well-recognized late effect of cancer therapy. In this article, a fine-needle aspiration (FNA) series of four cases is presented. There were three female patients and one male patient, with an age range of 28-55 yr (mean, 41). Two of the patients were irradiated for uterine cervical carcinoma while the other two received irradiation for malignant lymphoma. The time interval to the development of the postirradiation sarcoma ranged from 10 to greater than 20 yr. There were a postirradiation synovial sarcoma of the buttock region, malignant fibrous histiocytoma of the bone (femur), and rhabdomyosarcoma andmore » angiosarcoma of the retroperitoneum. A spectrum of cytologic findings was encountered, reflecting the specific types of sarcomas. Immunocytochemical studies performed on the aspirated material from the angiosarcoma demonstrated the utility of immunoperoxidase stains for ULEX europaeus agglutinin-1 (UEA-1) and, to a lesser degree, factor VIII-related antigen antibody, confirming the vascular nature of this malignancy. The FNA findings from all four cases demonstrated cytologic features that allowed recognition of this unusual complication of irradiation treatment. This article confirms the utility of FNA cytology in following patients with previous malignancies and differentiating a postirradiation sarcoma from recurrent carcinoma.« less

In summer 2010-2011 two outbreaks of Pseudomonas foliculitis occurred among bathers who used the swimming pools or whirlpools in two guest-room sites. The source of the infection was traced to the swimming pools or whirlpools, which had not been chlorinated and monitored routinely. Of 40 bathers, 25 (62.5%) developed Pseudomonas folliculitis 2-4 days after exposure. Typically the rash began as a pruritic erythematous papule on the buttocks, axilla, and extremities, with fever, adenopathy and otitis externa. In the culture of the pustules and bacterial examination grew Pseudomonas aeroginosa. Pseudomonas folliculitis was first described by McCausland and Cox in 1975. To the best of our knowledge, this is the first description of outbreaks in swimming pools or whirlpools in guest-room sites in Israel. This article describes the epidemiological and environmental health investigation of the two outbreaks. With the rising popularity of swimming pools and whirlpools in guest-room sites, physicians in the community and the emergency rooms may encounter this disease. We urge their real time report to the public health offices, in charge of the epidemiological inquires, aiming to prevent the occurrence of new cases or improper treatment of similar cases.

Case report. Proximal hamstring tendinopathy is a relatively uncommon overuse injury seen in runners. In contrast to the significant amount of literature guiding the evaluation and treatment of hamstring strains, there is little literature about the physical therapy management of proximal hamstring tendinopathy, other than the general recommendations to increase strength and flexibility. Two runners were treated in physical therapy for proximal hamstring tendinopathy. Each presented with buttock pain with running and sitting, as well as tenderness to palpation at the ischial tuberosity. Each patient was prescribed a specific exercise program focusing on eccentric loading of the hamstrings and lumbopelvic stabilization exercises. Trigger point dry needling was also used with both runners to facilitate improved joint motion and to decrease pain. Both patients were treated in 8 to 9 visits over 8 to 10 weeks. Clinically significant improvements were seen in pain, tenderness, and function in each case. Each patient returned to running and sitting without symptoms. Proximal hamstring tendinopathy can be difficult to treat. In these 2 runners, eccentric loading of the hamstrings, lumbopelvic stabilization exercises, and trigger point dry needling provided short- and long-term pain reduction and functional benefits. Further research is needed to determine the effectiveness of this cluster of interventions for this condition. Therapy, level 4.

2017-09-01

The article presents a case of an 18-year-old woman wounded by a shot fired from a distance with a hunting weapon. Because the location of the entrance and exit wounds initially seemed inconsistent with the reports (both wounds were described as "large and irregular in shape") and no photographs documenting the inflicted injuries were taken, the case was referred for an opinion to the Department of Forensic Medicine in Lodz. After a review of the medical records, radiology, the victim's clothing, and performance of an experiment using the gun and ammunition, it was established that the entrance wound was located on the abdomen, and the exit wound was located on the buttock. The initial problems with recognizing the entrance and exit wounds encountered by the surgical team were caused by bullet deformation. Before hitting the body, the projectile pierced a mobile phone that was in the pocket of the woman's jacket, subsequently causing a large atypical secondary entrance wound. The experiment confirmed that, when the projectile passed through an obstacle with consequent deformation, it caused more extensive gunshot wounds, both at the entrance and at the exit, as well as more severe damage to the bones.

This study was carried out to investigate the fit between university student's anthropometry and classroom furniture dimensions. In this cross-sectional and descriptive-analyzing study conducted in 2012, a total of 194 students (aged 18 through 30 years), were recruited randomly from Tabriz University of Medical Science community. The body size of each student was assessed using anthropometric measurements including shoulder height, elbow height, popliteal height, buttock-popliteal length, hip breadth and distance between elbows. Combinational equations defined the acceptable furni-ture dimensions according to anthropometry and match percentages were computed, according to either the existing situations assuming that they could use the most appropriate of the sizes available. Desk and seat height were higher than the accepted limits for most students (92.5% and 98.4%, respectively), while seat depth was appropriate for only 84.6% of students. The data indicate a mismatch between the students' bodily dimensions and the classroom furniture available to them. The chairs are too high and too deep and desks are also too high for the pupils. This situation may have negative effects on the sitting posture of the students especially when reading and writing. High mismatch percentages were found between furniture and stu-dents' anthropometry. The results confirm that furniture for university students should be selected and designed busied on their anthropometric dimensions.

Fractionated laser resurfacing corrects the inappropriate UVB response in geriatric skin.

Non-melanoma skin cancer is a disease primarily afflicting geriatric patients as evidenced by the fact that 80% of all non-melanoma skin cancers are diagnosed in patients over the age of 60 years. As such, geriatric skin responds to cancer-inducing UVB irradiation in a manner that allows the establishment of tumor cells. Currently, the only effective treatment for non-melanoma skin cancer is the removal of the tumors after they appear, indicating the need for a more cost-effective prophylactic therapy. Geriatric volunteers were treated with fractionated laser resurfacing therapy on either sun-protected (upper buttocks) or chronically sun-exposed (dorsal forearm) skin. Fractionated laser resurfacing therapy was shown to decrease the occurrence of senescent fibroblasts in geriatric dermis, increase the dermal expression of IGF-1, and correct the inappropriate UVB response observed in untreated geriatric skin. These responses to fractionated laser resurfacing were equal to the effects seen previously using the more aggressive wounding following dermabrasion. Furthermore, fractionated laser resurfacing was equally effective in both sun-protected and sun-exposed skin. The ability of fractionated laser resurfacing treatment to protect against the occurrence of UVB-damaged proliferating keratinocytes indicates the potential of fractionated laser resurfacing to reduce or prevent aging-associated non-melanoma skin cancer.

2017-08-01

In the last 8 years, several studies have documented that many adolescents acknowledge having exchanged sexually explicit cell phone pictures of themselves, a behavior termed sexting. Differences across studies in how sexting was defined, recruitment strategies, and cohort have resulted in sometimes significant differences in as basic a metric as what percentage of adolescents have sent, received, or forwarded such sexts. The psychosocial and even legal risks associated with sexting by minors are significantly serious that accurate estimates of its prevalence, including over time, are important to ascertain. In the present study, students (N = 656) from a single private high school were surveyed regarding their participation in sexting. Students at this same school were similarly surveyed four years earlier. In this second survey, reported rates of sending (males 15.8%; females 13.6%) and receiving (males 40.5%; females 30.6%) sexually explicit cell phone pictures (revealing genitals or buttocks of either sex or female breasts) were generally similar to those reported at the same school 4 years earlier. Rates of forwarding sexts (males 12.2%; females 7.6%) were much lower than those previously acknowledged at this school. Correlates of sexting in this study were similar to those reported previously. Overall, our findings suggest that sexting by adolescents (with the exception of forwarding) remains a fairly common behavior, despite its risks.

Ultraviolet (UV) exposure to the human skin reduces triglycerides contents and lipid synthesis in the subcutaneous (SC) fat. Because adiponectin and leptin are the most abundant adipokines from the SC fat, we aim to investigate how they interact with UV exposure and skin aging. The expressions of adiponectin and leptin were significantly decreased in SC fat of sun-exposed forearm skin, in comparison with that of sun-protected buttock skin of the same elderly individuals, indicating that chronic UV exposure decreases both adipokines. Acute UV irradiation also decreased the expressions of adiponectin and leptin in SC fat. The expressions of adiponectin receptor 1/2 and leptin receptor were significantly decreased in the dermis as well as in SC fat. Moreover, while exogenous adiponectin and leptin administration prevented UV- and TNF-α induced matrix metalloproteinase (MMP)-1 expression, they also increased UV- and TNF-α induced reduction of type 1 procollagen production. Silencing of adiponectin, leptin or their receptors led to an increased MMP-1 and a decreased type 1 procollagen expression, which was reversed by treatment with recombinant human adiponectin or leptin. In conclusion, UV exposure decreases the expression of adiponectin and leptin, leading to the exacerbation of photoaging by stimulating MMP-1 expression and inhibiting procollagen synthesis.

Estimation of skeletal muscle metastases (SMMs) at the time of diagnosis and/or initial staging of lung cancer. Retrospective evaluation of clinical charts and imaging data suggestive of SMMs of patients with histology-proved lung cancer over a 5-year period. SMMs were identified in 46 out of 1,754 patients. Single and multiple (62.9% of cases) SMMs were detected by total body multi-detector computed tomography (MDCT). They were associated with poorly differentiated (43%) and advanced adenocarcinomas (52%) without clinically relevant symptoms and/or signs. Psoas and buttock muscles were most frequently involved (33.3%). MDCT findings consisted of well-defined homogeneously hyperdense oval masses (31%), lesions with ring-like enhancement and central hypoattenuation (68%), or large abscess-like necrotic lesions (24%). Sonography revealed well-defined hypoechoic masses (41.6%), ill-defined hypoechoic lesions (33.3%), or anechoic areas with a necrotic centre (25%). Positron emission tomography revealed that all SMMs were metabolically active. SMMs are uncommon but not negligible in lung cancer, with an estimated prevalence of 2.62% in our series. Although histology remains the recommended method, use of high-performance imaging techniques and increased clinical suspicion may improve their early detection. Efforts addressing their effect on the natural history of lung cancer are needed.

Trials of interventions for PPH prevention and treatment rely on different measurement methods for the quantification of blood loss and identification of PPH. This study's objective was to compare measures of blood loss obtained from two different measurement protocols frequently used in studies. Nine hundred women presenting for vaginal delivery were randomized to a direct method (a calibrated delivery drape) or an indirect method (a shallow bedpan placed below the buttocks and weighing the collected blood and blood-soaked gauze/pads). Blood loss was measured from immediately after delivery for at least one hour or until active bleeding stopped. Significantly greater mean blood loss was recorded by the direct than by the indirect measurement technique (253.9 mL and 195.3 mL, respectively; difference = 58.6 mL (95% CI: 31-86); p < 0.001). Almost twice as many women in the direct than in the indirect group measured blood loss > 500 mL (8.7% vs. 4.7%, p = 0.02). The study suggests a real and significant difference in blood loss measurement between these methods. Research using blood loss measurement as an endpoint needs to be interpreted taking measurement technique into consideration. This study has been registered at clinicaltrials.gov as NCT01885845.

To test the effect of a new coverlet device, allowing air circulation at the body/underlying surface interface, on skin microclimate management. This prospective observational pilot study took place in a 15-bed university-affiliated intensive care unit. Overall, 34 mechanically ventilated patients were included. Skin humidity and temperature were monitored before and after the implementation of the tested device at the occiput, scapulas, buttocks and sacrum. Humidity and temperature were evaluated through surface skin impedance and an infra-red thermometer, respectively. Health professionals were asked to evaluate the device. After implementation of the coverlet device, there was a rapid, sustained and significant decrease in skin humidity at all sites ranging from 6 % to 15 %, excluding the occiput. Skin temperature also significantly decreased from 1 % at both scapulas, but not at the other studied body sites. No side effects were observed. Health professionals reported that the device was easy and quick to install. Although they did not report a subjective improvement in skin moisture or temperature, they considered the device to be efficient. Although limited by its design, this pilot study suggests a good efficacy of the studied device on skin microclimate management. Further data are warranted to test the clinical implications of our findings.

To evaluate direct puncture embolization of the internal iliac artery with hemostatic gelatin sponge particles to treat pernicious placenta previa coexisting with placenta accreta during cesarean delivery. A retrospective study was conducted of data from women with pernicious placenta previa and placenta accreta who underwent direct puncture embolization of the internal iliac artery during cesarean delivery at a center in China between September 1, 2013, and February 28, 2015. Information regarding surgical procedures, operative data, and outcomes during hospitalization were obtained from medical records. The procedure was successful in all 16 cases included. Mean operative time was 78 minutes (range 65-90) and mean estimated blood loss was 1550 mL (range 1000-2500). Complications such as fever, buttock pain, or acute limb ischemia were not observed. The procedure was performed after partial cystectomy for two patients with bladder invasion. Postoperative Doppler imaging indicated uterine recovery and normalized uterine blood flow in all patients. Direct puncture embolization of the internal iliac artery during cesarean delivery was a safe, effective, simple, and rapid method to control hemorrhage among women with pernicious placenta previa and placenta accreta.

Background: Acne inversa (AI), also called hidradenitis suppurativa, is a chronic, inflammatory, recurrent skin disease of the hair follicle. Familial AI shows autosomal-dominant inheritance caused by mutations in the γ-secretase genes. This study was aimed to identify the specific mutations in the γ-secretase genes in two Chinese families with AI. Methods: In this study, two Chinese families with AI were investigated. All the affected individuals in the two families mainly manifested with multiple comedones, pitted scars, and a few inflammatory nodules on their face, neck, trunk, axilla, buttocks, upper arms, and thighs. Reticulate pigmentation in the flexures areas resembled Dowling-Degos disease clinically and pathologically. In addition, one of the affected individuals developed anal canal squamous cell carcinoma. Molecular mutation analysis of γ-secretase genes including PSENEN, PSEN1, and NCSTN was performed by polymerase chain reaction and direct DNA sequencing. Results: Two novel mutations of PSENEN gene were identified, including a heterozygous missense mutation c.194T>G (p.L65R) and a splice site mutation c.167-2A>G. Conclusions: The identification of the two mutations could expand the spectrum of mutations in the γ-secretase genes underlying AI and provide valuable information for further study of genotype-phenotype correlations.

In 1977 Rautenstrauch and Snigula reported on two sisters with a previously undescribed, progeria-like syndrome. Two years later Wiedemann described two unrelated males with the same condition. Since than only a few published cases appeared in the literature. We had the opportunity to study a boy affected by this extremely rare condition. This boy was born after intrauterine growth retardation. At birth two natal teeth were present. OFC was normal despite apparent macrocephaly. During infancy a progeroid appearance was noted with sparse hair, prominent scalp veins, greatly widened anterior fontanelles, malar hypoplasia, and generalized lipoatrophy. The face was triangular with a small maxilla and a protuding chin, the eyes were low-set, the eyebrows and eyelashes were scanty. At the age of 3.5 years there was striking general deficiency of subcutaneous fatty tissue apart from accumulation of adipose tissue on the buttocks and flanks, growth was retarded, mental development was at the low borderline of normal. Cholesterolemia was at the upper range of normal, there was an increase of triglycerides: 3.31 mmol/L (Normal < 1 mmol/L). Other progeroid syndromes such as Hutchinson-Guilford, Berardinelli-Seip, De Barsy, leprechaunism, Cockayne and Hallerman-Streiff could be excluded as well as the CDG syndrome. This condition is most probably inherited as an autosomal recessive trait.

Differential diagnosis of endometriosis in a young adult woman with nonspecific low back pain.

PubMed

Troyer, Mark R

2007-06-01

Endometriosis is a common gynecological disorder that can cause musculoskeletal symptoms and manifest as nonspecific low back pain. The patient was a 25-year-old woman who reported the sudden onset of severe left-sided lumbosacral, lower quadrant, buttock, and thigh pain. The physical therapist examination revealed findings suggestive of a pelvic visceral disorder during the diagnostic process. The physical therapist referred the patient for medical consultation, and she was later diagnosed by a gynecologist with endometriosis and a left ovarian cyst. The patient underwent laser laparoscopy and excision of the ovarian cyst followed by a regimen of gonadotropin-releasing hormone agonists. The intervention resulted in abolition of the lower quadrant pain and a significant reduction of the back and leg pain that enabled the patient to return to her normal activities. A thorough physical therapist examination that considers all of the musculoskeletal, visceral, and psychosocial components is essential to identify pelvic disorders such as endometriosis and other disease processes during the differential diagnosis of nonspecific low back pain. Medical consultation is necessary to provide proper diagnosis and intervention of endometriosis, but physical therapists also may have an important role in the identification of endometriosis and the management of the musculoskeletal aspects of the disorder.

Threshold level for measurement of UV sensitivity: reproducibility of phototest.

PubMed

Lock-Andersen, J; Wulf, H C

1996-08-01

The ultraviolet (UV) sensitivity is determined by a phototest where the skin is exposed to well-defined doses of UV radiation and the resulting erythema is graded by visual scoring after 20-24 h. In this study we wanted to estimate the reproducibility of erythema assessment in phototesting. Twenty-one healthy Caucasians with skin types I to IV were phototested on UV un-exposed buttock skin using a xenon lamp solar simulator. Twenty-four hours after UV exposure eight physicians independently graded the erythema reactions two times. Data were analysed using inter- and intra-observer agreement and kappa statistics, which adjusts for agreement that could be caused by chance alone. Observed agreement and kappa statistics were found to decrease with increasing intensity of erythema and to be lower for skin types III and IV compared to skin types I and II. Intra-observer agreement was uniformly better than inter-observer agreement. The difference between observers assessment could be as much as three clinical erythema grades. Physicians's previous experience with phototesting only had a minor influence on agreement. In conclusion, phototesting is based on subjective assessment of erythema and is not as precise and reproducible as expected. Agreement was better for barely perceptible erythema than for erythema with a well-defined border and we therefore recommend that the barely perceptible erythema reaction should be used for measurement of the minimal erythema dose.

We report the aerobic and anaerobic microbiology of secondarily infected poison ivy dermatitis. The study involved retrospective review of clinical and microbiology laboratory records of patients with secondarily infected poison ivy lesions. Bacterial growth was noted in 33 specimens. Aerobic or facultative anaerobic bacteria only were present in 18 (55%) patients, anaerobic bacteria only in seven (21%), and mixed anaerobic-aerobic bacteria in eight (24%). Forty-five isolates were recovered (1.4 per specimen): 27 aerobic or facultative anaerobic bacteria, and 18 strict anaerobes. The predominant aerobic and facultative anaerobic bacteria were Staphylococcus aureus (13 isolates) and group A beta-haemolytic streptococci (six). The predominant anaerobes were Peptostreptococcus spp. (seven isolates), pigmented Prevotella and Porphyromonas spp. (four) and Fusobacterium spp. (two). Single bacterial isolates were recovered in 18 (55%) patients, eight of which were S. aureus. Nineteen of the organisms isolated from 16 (48%) patients produced the enzyme beta-lactamase. Organisms that resided in the mucous membranes close to the lesions predominated in those infections. Enteric gram-negative rods and Bacteroides fragilis group predominated in leg and buttock lesions. Group A beta-haemolytic streptococci, pigmented Prevotella and Porphyromonas and Fusobacterium spp. were most frequently recovered from lesions of the finger, face and neck. The polymicrobial aetiology of secondarily infected poison ivy lesions, and the association of bacterial flora with the anatomical site of the lesions, are demonstrated.

To examine the clinical features of patients with non-clostridial gas gangrene (NCGG) at our hospital and identify risk factors for in-hospital mortality. This study included 24 patients with NCGG who were hospitalized in our medical facility from April 2005 to March 2015. The clinical features of NCGG were reviewed, and the characteristics of 6 patients who died in hospital and 18 who survived were compared to investigate risk factors. The median time from symptom onset to hospital arrival was 168 h. The causative agent was Klebsiella pneumoniae in 8.3% and mixed infection in 91.7%; 83.3% of patients had diabetes, and one patient had no obvious underlying disease. The site of infection was the neck in 4.2%, the thoracoabdominal wall and retroperitoneum in 12.5% each, the back in 33.3%, the buttocks in 25.0%, the perineum in 20.8%, and the extremities in 45.8%. Retroperitoneal infection, blood lactate ≥ 4.0 mmol/L, and Japanese Association for Acute Medicine disseminated intravascular coagulation (DIC) score ≥ 4 on emergency department (ED) arrival were significantly higher in non-survivors than in survivors. NCGG tends to develop in patients with diabetes, and in-hospital mortality rates are still high. Retroperitoneal infection, hyperlactatemia, and DIC on ED arrival are risk factors for in-hospital mortality.

During a 2-year period, eight patients sustained burns caused by the tipping over of electric stoves. In seven of these cases, children aged 2 to 4 years stood up on the open oven door of a stove. The stove then tipped forward, and a pot of boiling liquid on the stove spilled onto the child, who fell forward across the oven door. The general area of involvement was back and buttocks, with spattered areas elsewhere on the body. In one other case, an older child, aged 8, sat on the open oven door and was burned when a pot fell on him. The weight of the children ranged from 12.7 to 20 kilograms, with a mean of 15.2 kilograms. The 8-year old weighed 14.9 kilos. Burn size ranged from 3% to 30%, with a mean of 16.75%. All burns were second-degree and were treated by debridement and coverage with either porcine grafts or Biobrane (Dow Hickman Pharmaceuticals, Inc.). Healing was satisfactory in all cases. Hospital stay ranged from 2 to 20 days. The increase in the use of electric stove has led to a situation in which children, usually toddlers, can overbalance the stove and bring down the pots sitting on the heating elements. This represents another mechanism by which young children can be injured in the kitchen; the awareness of this should be disseminated.

Industrial-grade silicone injections causing intermittent bilateral malar swelling: review of safety and efficacy of techniques and products available.

Silicone and other fillers have become a popular aid to increase soft tissue density, decrease static skin rhytids, and treat muscle wasting, particularly in the face. As a result, injectable silicone has become popular in patients with the human immunodeficiency virus (HIV). It has been postulated that highly active antiretroviral therapy detrimentally induces the physiologic process of fat atrophy of the temporal and buccal fat pads of the face and regional fat wasting of the arms, legs, and buttocks and that HIV protease inhibitors may induce fat atrophy by binding and inhibiting homologous human proteins that are involved in fat metabolism. The classic hollowed-out facial appearance linked to HIV positivity can have detrimental social implications in infected patients who are otherwise very functional. In consequence, facial implantation, fat transplantation, and dermal and subcutaneous fillers have been used to aid in the restoration of facial appearance. This report describes the case of a patient who underwent multiple rounds of silicone injections and complained of intermittent facial swelling and pain long after the injections. The authors report on the safety of specific medical-grade injectable fillers and techniques found to be safely effective, especially in the HIV-positive population.

Febuxostat is now recommended as the first-line pharmacological urate-lowering therapy for gout in the American College of Rheumatology guidelines. There is no case of rhabdomyolysis associated with febuxostat among reported side effects of the drug. Our objective is to report on a case of rhabdomyolysis associated with initiation of febuxostat in a patient with chronic kidney disease (CKD). A 73-year-old male patient visited our emergency room due to progressive weakness in both lower extremities starting 3 days earlier. Ten days before presentation, his primary physician had changed his prescription from allopurinol to febuxostat (80 mg) because of poor control of uric acid levels. There was tenderness in both thighs. Initial creatinine kinase (CK) was 7652 U/L (0-170 U/L), and a bone scan using (99m) Tc-HDP revealed strong uptake in soft tissues in both thighs and buttocks. Electromyography (EMG) and nerve conduction velocity (NCV) showed abnormal spontaneous activities (ASA), suggesting myopathy, not nerve damage. On day 7 of admission, after conservative management and febuxostat withdrawal, he could walk on the ward. He is being followed in our clinic as an outpatient with no sequelae. This report is first case of rhabdomyolysis associated with initiation of febuxostat. Febuxostat should be withdrawn when rhabdomyolysis is confirmed. © 2014 John Wiley & Sons Ltd.

Acute UV irradiation increases heparan sulfate proteoglycan levels in human skin.

Glycosaminoglycans are important structural components in the skin and exist as various proteoglycan forms, except hyaluronic acid. Heparan sulfate (HS), one of the glycosaminoglycans, is composed of repeated disaccharide units, which are glucuronic acids linked to an N-acetyl-glucosamine or its sulfated forms. To investigate acute ultraviolet (UV)-induced changes of HS and HS proteoglycans (HSPGs), changes in levels of HS and several HSPGs in male human buttock skin were examined by immunohistochemistry and real-time quantitative polymerase chain reaction (qPCR) after 2 minimal erythema doses (MED) of UV irradiation (each n = 4-7). HS staining revealed that 2 MED of UV irradiation increased its expression, and staining for perlecan, syndecan-1, syndecan-4, CD44v3, and CD44 showed that UV irradiation increased their protein levels. However, analysis by real-time qPCR showed that UV irradiation did not change mRNA levels of CD44 and agrin, and decreased perlecan and syndecan-4 mRNA levels, while increased syndecan-1 mRNA level. As HS-synthesizing or -degrading enzymes, exostosin-1 and heparanase mRNA levels were increased, but exostosin-2 was decreased by UV irradiation. UV-induced matrix metalloproteinase-1 expression was confirmed for proper experimental conditions. Acute UV irradiation increases HS and HSPG levels in human skin, but their increase may not be mediated through their transcriptional regulation.

Failed Percutaneous Vertebroplasty Due to Insufficient Correction of Intravertebral Instability in Kummell's Disease: A Case Report.

Kummell's disease, caused by osteonecrosis of the vertebral body, is a cause of vertebral collapse. In Kummell's disease, intravertebral instability from nonunion between the cement and bone after percutaneous vertebroplasty (PVP) can cause persistent severe pain and dysfunction. A 75-year-old woman presented with severe pain in the lower back, both buttocks, groin, and both posterior thighs for a period of 30 days. Lumbar radiographs and magnetic resonance images showed an acute compression fracture of the first lumbar vertebra with an intravertebral cleft filled with fluid. The patient underwent PVP for the L1 compression fracture; however, this failed to provide sufficient pain relief. The patient was re-evaluated with dynamic radiography, and intravertebral instability and bone cement displacement of the L1 vertebra were detected. Repeat PVP was performed. After the procedure, intravertebral instability was restored and her pain completely subsided. PVP is a good treatment choice for symptomatic Kummell's disease. However, there is no consensus on the best technique of injecting bone cement to achieve optimal results. It is important to inject more bone cement than the volume of the intravertebral cleft to prevent instability caused by nonunion in PVP for Kummell's disease. We report a case of failed PVP because of insufficient correction of intravertebral instability in Kummell's, along with a review of the literature. © 2017 World Institute of Pain.

The purpose of this study was to examine the relationship of subepidermal moisture and early stage pressure injury by visual skin assessment in elderly Korean. Twenty-nine elderly participated at a particular nursing home. Data were collected for 12 weeks by one wound care nurse. Visual skin assessment and subepidermal moisture value were measured at both buttocks, both ischia, both trochanters, sacrum, and coccyx of each subject once a week. Subepidermal moisture value of stage 1 pressure injury was significantly higher than that of no injury and blanching erythema. After adjustment with covariates, odds ratios of blanching erythema to normal skin and stage 1 pressure injury to blanching erythema/normal skin were statistically significant (p < 0.05). Odds ratio of blanching erythema to normal skin was 1.003 (p = .047) by 1-week prior subepidermal moisture value, and that of concurrent subepidermal moisture value was 1.004 (p = .011). Odds ratio of stage 1 pressure injury to normal skin/blanching erythema was 1.003 (p = .005) by 1-week prior subepidermal moisture value, and that for concurrent subepidermal moisture value was 1.007 (p = .030). Subepidermal moisture was associated with concurrent and future (1 week later) skin damage at both trochanters. Subepidermal moisture would be used to predict early skin damage in clinical nursing field for the effective pressure injury prevention. Copyright © 2018. Published by Elsevier Ltd.

Sciatic nerve injuries following total hip arthroplasty are disabling complications. Although degrees of injury are variable from neuropraxia to neurotmesis, mechanical irritation of sciatic nerve might be occurred by protruding hardware. This case shows endoscopic decompression for protruded acetabular screw irritating sciatic nerve, the techniques described herein may permit broader arthroscopic/endoscopic applications for management of complications after reconstructive hip surgery. An 80-year-old man complained of severe pain and paresthesias following acetabular component revision surgery. Physical findings included right buttock pain with radiating pain to lower extremity. Radiographs and computed tomography imaging showed that the sharp end of protruded screw invaded greater sciatic foramen anterior to posterior and distal to proximal direction at sciatic notch level. A protruding tip of the acetabular screw at the sciatic notch was decompressed by use of techniques gained from experience performing endoscopic sciatic nerve decompression. The pre-operative pain and paresthesias resolved post-operatively after recovering from anesthesia. This case report describes the first documented endoscopic resection of the tip of the acetabular screw irritating sciatic nerve after total hip arthroplasty. If endoscopic resection of an offending acetabular screw can be performed in a safe and minimally invasive manner, one can envision a future expansion of the role of hip arthroscopic surgery in several complications management after total hip arthroplasty.

We investigated the presence of femoral head avascular osteonecrosis (FHAVN) by a selective investigation with MRI at follow-up. A total of 331(200 men, 131 women) renal transplants were included. They were transplanted at the mean age of 31.4 (9-63) years. The mean follow-up time of all patients after transplantation was 60.6 (6-233) months, and the mean current age 36.6 (11-66) years. All transplants filled out a questionnaire on musculoskeletal symptoms and underwent a detailed clinical examination. Magnetic resonance imaging was done in cases of hip joint pain in groin, buttock, thigh and knee and in 50 asymptomatic transplants. FHAVN were identified according to Ficat Arlet classification. 43(13%) patients reported pain without previous trauma. In the clinical examination, limited ranges of motion of the hip were noted in 13 of them. FHAVN was detected in 11 of 43 patients. Disease was bilateral in two of the eleven patients. Of the 662 femoral heads, 43 were associated with hip pain whereas the remaining 619 were asymptomatic. Avascular osteonecrosis was not confirmed in the asymptomatic 100 hips with magnetic resonance imaging. A selective investigation of FHAVN may be used to diagnose in renal allograft recipients with painful hips at follow-up. With a retrospective selective analysis, the presence of FHAVN was low among renal transplantation recipients at the end of the study.

To describe the distribution of bodily pain and identify common patterns of pain localization after traffic injury. Cross-sectional analysis of a population-based cohort of 6481 Saskatchewan residents who were treated or filed an auto insurance claim within 30 days of traffic injury or both. The prevalence of pain in each of 13 body areas was calculated and compared with pain confined exclusively to each of these areas. Principal component analysis was used to identify the main patterns of pain localization after traffic injury. Irrespective of pain in other areas, 86% of respondents reported posterior neck pain, 72% indicated head pain, and 60% noted lumbar back pain. Ninety-five percent of claimants reported some pain within the posterior trunk region, comprising the posterior neck, shoulder, mid-back, lumbar, and buttock areas. Only 0.4% of respondents reported posterior neck pain only. Four main patterns accounted for 60% of the variance in pain localization: 1) upper anterior trunk and upper extremity pain; 2) head, posterior neck, and upper posterior trunk pain; 3) low back pain; and 4) lower anterior trunk and lower extremity pain. Pain after traffic injury is most commonly reported in multiple body areas; isolated neck pain is extremely rare. These results have implications for clinical management of traffic injuries and interpretation of whiplash-related trials.

Long-term results of blunt suction lipectomy assessed by a patient questionnaire survey.

A questionnaire was sent to 1339 consecutive patients who had undergone blunt suction lipectomy during the period between April 1984 and April 1987. Seventy-four percent replied, thus providing information about the results of 1929 procedures. The overall reported rate of satisfaction was 76 percent, with no significant difference between males and females. Highest satisfaction referred to pseudogynecomastia, submental area, iliac crest, and lower extremities on females. The rate of dissatisfaction was 6 percent. Dissatisfaction was associated most frequently with lipectomy of the buttocks. Underresection was reported for 30 percent and over-resection for 2.2 percent of the procedures. The latter, in particular, seemed to lead to dissatisfied patients. Asymmetry was reported for 19 percent of the procedures. Recurrence ("return") of fatty tissue was reported for 29 percent at the resection site. Thirty percent of the patients reported compensatory increase ("came back elsewhere") in fat deposits in nontreated locations. Self-reported weight gain was found to be a significant risk factor for both types of "regrowth." Irregularities were the most frequently reported permanent changes to skin. There were twice as many negative as positive changes to skin. Most of the patients had benefited personally from the surgery and were willing to consider undergoing lipoplasty again. All in all, the long-term results of blunt suction lipectomy are satisfactory.

Laparoscopic hand-assisted pancreaticoduodenectomy: initial UK experience.

PubMed

Ammori, B J

2004-04-01

By and large, the limited world experience with laparoscopic pancreaticoduodenectomy (PD) has been unfavorable, but the laparoscopic hand-assisted approach to PD has recently shown promising results. We report the first successful UK experience with laparoscopic hand-assisted PD (LHAPD). A 62-year-old man who presented with painless obstructive jaundice was found at endoscopy, to have an ampullary tumor. Preoperative biopsy specimens confirmed the diagnosis of an adenocarcinoma, and CT showed no evidence of either vascular involvement or metastatic disease. A staging laparoscopy showed no intraabdominal metastases, and an LHAPD was performed using a Gelport. The intraoperative course was uneventful. Two units of blood were transfused intraoperatively, but no postoperative blood transfusion was required. The operative time was 11 h (plus a 30-min break). The patients postoperative recovery was uneventful except for superficial pressure sores over the buttocks and elbows. The patient resumed oral fluid and dietary intake on the 1st and 3rd postoperative days, respectively, and was discharged from hospital on the 9th postoperative day. Histology demonstrated an ampullary adenocarcinoma with clear resection margins and involvement of two of the 13 lymph nodes examined. At 2-month follow-up, the patient remains well and is receiving adjuvant chemotherapy. LHAPD achieves good oncological clearance and can be performed safely in selected patients. The early promising results with this approach will undoubtedly encourage wider adoption of this procedure and are likely to widen the selection criteria.

Autoimmune/inflammatory syndrome induced by adjuvant (ASIA) includes the following conditions: siliconosis, Gulf War syndrome, macrophagic myofasciitis syndrome, and post-vaccination phenomena. Afterward, other syndromes have been recognized, such as in ASIA by mineral oil (ASIA-MO). These conditions are triggered by adjuvants and they are the result of the interplay of genetic and environmental factors. ASIA-MO is defined as the infiltration of oily type modeling substances for cosmetic purposes. It has been reported in many countries and used surreptitiously. Pathogenesis of ASIA-MO is not clear, but is characterized by chronic granulomatous inflammation, like the pristane model in mice, with increase of proinflammatory cytokines: type I interferons (IFNα and IFNß), systemic lupus erythematosus (SLE), and erosive arthritis. In humans, an increase of interleukin 1 (IL-1) has been found. Clinical spectrum of ASIA-MO is heterogeneous, varying from mild to severe and being local and systemic. The systemic manifestations can be non-specific and specific, meeting criteria for any autoimmune disease (AID), i.e., SLE, rheumatoid arthritis, and systemic sclerosis, among others. The areas of the body where the mineral oil is mostly applied include the following: buttocks (38-72%), breasts (12-16%), lower extremities (18-22%), and face (6-10%). The penis augmentation is also common. Treatment is focused on local and systemic manifestations and requires medical and surgical management representing a challenge for the physician.

The scabies infects about 300 million people worldwide. Its spread is linked to living conditions especially in economically poor countries. In Central African Republic (CAR) we do not have data on this disease often causes morbidity and expenses, and the disease is often confused and poorly treated. The authors' goal was to describe the epidemiological, clinical and therapeutic characteristics of scabies in Bangui. This was a cross-sectional study by counting records of cases of scabies observed in the dermatology and venereology department of Bangui from 1 January 2006 to 31 December 2010. The diagnosis was based mainly on the combination of a concept of pruritus predominantly night with the notion of contagion and preferential localization of lesions. Three hundred and seventy six cases of scabies were identified from a total of 6391 patients (a hospital prevalence of 5.88%) with high frequency among the population aged 0 to 9 years (33%), an important achievement of the disadvantaged classes (preschool age and pupils / students respectively 25.5% and 26.3%), a prevalence of scabies nodules as type of clinical lesion, localization predominantly on buttocks and the most common complication of eczema-type (19.9 %). Benzyl benzoate solution at 25% applied for 2 consecutive days yielded very satisfactory results (96.7% on day 28) in all forms. The scabies is present in CAR with classical clinical and epidemiological aspects. We recommend first-line benzyl benzoate in two days of application.

The purpose of this study was to retrospectively evaluate the sonographic findings of ruptured epidermal inclusion cysts in superficial soft tissue, with an emphasis on shapes, pericystic changes, and pericystic vascularity. The cases of 61 patients with surgically confirmed epidermal inclusion cysts were reviewed, and 13 patients were found to have ruptured cysts. The Ethics Committees of our institutions did not require patient approval or informed patient consent for this retrospective study. We evaluated the shapes, sizes, locations, pericystic changes, and pericystic vascularity for the 13 cases. The shapes of the ruptured epidermal inclusion cysts were classified into 3 types: with lobulations (type I, 2 cases), with protrusions (type II, 8 cases), and with abscess pocket formations (type III, 3 cases). The mean long diameter of the cysts was 3 cm. Common sites of ruptured epidermal inclusion cysts were the plantar surface of the metatarsophalangeal joint (4 cases) and buttocks (3 cases). Pericystic changes were noted in all of the type II and III cysts. Increased vascularity on color Doppler sonography was prominent in 3 type II cysts and 3 type III cysts. Deep abscess formation was noted in the epidermal inclusion cysts, especially for the type III cysts. A ruptured epidermal inclusion cyst visualized by sonography had variable shapes; the sonographic findings can be useful for obtaining a correct diagnosis of a ruptured epidermal inclusion cyst.

Color assessment of human skin is an important index both in dermatology and in cosmetology. Skin color measured in 407 Chinese women selected from four different cities in China is reported in the 1976 Commission International de L'eclairage (CIE)-color space, according to the skin color typing method proposed by Chardon et al. in 1991. The skin color of buttocks and hands, which represent sun unexposed and exposed sites, respectively, were measured with a Minolta 2500d chromameter. Individual typology angle (ITA degrees) of each volunteer was calculated based on the measured L* and b* values and her skin complexion was graded accordingly. The results show that most of the volunteers had a "light" skin color at their unexposed sites, namely grade II (65.5%), and then grade III (intermediate, 23.1%), and I (very light, 9.6%). The skin colors at exposed sites of the studied group were mainly grade III (intermediate, 45.7%), followed by grade IV (tan, 42.0%) and II (light, 7.9%). The difference among the investigated cities, the relationship between skin color and ages, and the complexion changes from unexposed site to exposed site were analyzed based on the data from the research. The authors believed that the present results might basically represent the complexion conditions of Chinese women.

The purpose of this study was to evaluate and compare resistance exercise training with and without pelvic stabilization on the development of isolated lumbar extension strength. Isometric torque of the isolated lumbar extensor muscles was measured at seven positions through a 72 degree range-of-motion on 47 men and 30 women before and after 12 weeks of variable resistance lumbar extension training. Subjects were assigned to either a group that trained with pelvic stabilization (P-STAB, n = 21), a group that trained without pelvic stabilization (NO-STAB, n = 41), or a control group that did not train (n = 15). Subjects trained once a week with 8 to 12 repetitions to volitional exhaustion. The P-STAB and NO-STAB groups showed significant (p < or = 0.05) and similar increases in the weight load used for training (P-STAB = 24.1 +/- 9.4kg; NO-STAB = 19.4 +/- 11.0kg) during the 12-week training period. In contrast, posttraining isometric torque values describing isolated lumbar extension strength improved only for the P-STAB group (23.5%, p < or = 0.05) and not for the NO-STAB group (-1.2%, p > 0.05) relative to controls. These data indicate that pelvic stabilization is required to effectively train the lumbar extensor muscles. The increased training load for the NO-STAB group is probably the result of exercising the muscles involved in pelvic rotation (hamstring and buttock muscles).

Fox Den Disease: An Interesting Case Following Delayed Diagnosis.

2015-06-01

Pyoderma fistulans sinifica, also known as fox den disease, is a rare and poorly understood inflammatory disorder of the skin and subcutaneous tissues. This disorder is often mistaken for other inflammatory skin disorders and treated inappropriately. The authors describe the case of a 53-year-old male who presented to the colorectal surgery service with a longstanding diagnosis of perirectal Crohn's disease. Despite aggressive immunosuppression and numerous surgical procedures, the patient continued to have unrelenting purulent drainage from the skin of his buttocks. Following wide excision of the affected skin and subcutaneous tissues by the colorectal surgeon, the plastic surgery team reconstructed the 30 cm x 55 cm wound using a combination of local flaps and skin grafts. The initial pathology report of the excised specimen confirmed the presence of nonspecific abscesses and inflammation. Upon special request by the plastic surgery team, the sample was resectioned with the specific intent of establishing a diagnosis of fox den disease. The additional slides met the criteria for an unequivocal diagnosis of fox den disease. Immunosuppression was discontinued and the patient healed his wounds without complication. Fox den disease is often overlooked because of the obscurity of the disease and the special histological sectioning needed to establish a diagnosis. In this case, the patient was unnecessarily treated with immunosuppressive drugs for more than 3 decades because of a misdiagnosis. With increased awareness of fox den disease, perhaps its pathophysiology can be better elucidated as more patients are appropriately diagnosed and treated.

Multicenter prospective study with a crossover design. The objective of this study is to compare the efficacy of limaprost alfadex (LP) and elcatonin (EL) for lumbar spinal stenosis (LSS) patients with concurrent osteoporosis. It has been increasingly important to improve quality of life by establishing appropriate conservative treatments for LSS patients with concurrent osteoporosis who will presumably continue to increase due to the percentage of the aging elevations, however there is no prospective study. A total of 19 patients with LSS and concurrent osteoporosis were enrolled in this study. The patients were divided into two groups and compared using a crossover design. The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) and short-form (SF)-8 health survey scale were used for clinical evaluations. There was a significant improvement of buttock-leg pain and numbness in the EL group. A significant improvement of impaired walking function was noted for the LP group according to the JOABPEQ while the rest of the items in the JOABPEQ showed no significant differences. The SF-8 health survey revealed that somatic pains and physical summary scores in the EL group and physical functioning and physical summary scores in the LP group tended to improve but not to any statistically significant extents. Concomitant uses of EL may be useful in patients who do not respond satisfactorily to the treatments of LP for 6-8 weeks.

Endovascular treatment of aortoiliac aneurysms near or involving the hypogastric artery (HGA) requires HGA occlusion before endografting to avoid retrograde filling of the aneurysm. The purpose of this study is to evaluate clinical outcomes of bilateral HGA occlusion and determine if benefits gained by endovascular aneurysm repair (EVAR) outweigh the morbidity associated with the procedure. Between 1999 and 2004, 128 patients with abdominal aortic aneurysm (AAA) were treated with bifurcated endograft placement. Bilateral coverage or embolization of HGAs was performed in 14 patients (10.9%). Embolization was achieved by deployment of coils and coverage was accomplished by extending the endoprosthesis into the external iliac artery. Clinical follow-up and computed tomographic angiography were performed at 1, 3, 6, 9, and 12 months and annually thereafter to detect potential aneurysm growth and endoleaks. During follow-up (range, 1-72 months), buttock claudication was noted in four patients (28.6%), including unilateral claudication in two and bilateral claudication in two. One patient experienced claudication longer than 12 months, which resolved within 18 months. De novo erectile dysfunction was seen in one patient, and pelvic ischemia was not found in any patient. There was no evidence of endoleak, aneurysm enlargement, or death associated with HGA occlusion. In our series, complications of bilateral HGA occlusion before EVAR were moderate and resolved over time. The benefits gained from EVAR outweigh the clinical problems caused by bilateral HGA occlusion, as there are no technical complications added to the EVAR procedure.

To determine the association of self-perceived fat gain or fat loss in central and peripheral body sites with adherence to highly active antiretroviral therapy (HAART) in HIV-seropositive women. 1,671 women from the Women's Interagency HIV Study who reported HAART use between April 1999 and March 2006 were studied. Adherence was defined as report of taking HAART >/= 95% of the time during the prior 6 months. Participant report of any increase or decrease in the chest, abdomen, or upper back in the prior 6 months defined central fat gain and central fat loss, respectively. Report of any increase or decrease in the face, arms, legs or buttocks in the prior 6 months defined peripheral fat gain or peripheral fat loss. Younger age, being African-American (vs. White non-Hispanic), a history of IDU, higher HIV RNA at the previous visit, and alcohol consumption were significant predictors of HAART non-adherence (P < 0.05). After multivariate adjustment, self-perception of central fat gain was associated with a 1.5-fold increased odds of HAART non-adherence compared to no change. Self-perception of fat gain in the abdomen was the strongest predictor of HAART non-adherence when the individual body sites were studied. Women who perceive central fat gain particularly in the abdomen are at risk for decreased adherence to HAART despite recent evidence to suggest that HIV and specific antiretroviral drugs are more commonly associated with fat loss than fat gain.

Scabies is a common contagious cutaneous disease and usually affects the young, characterized by polymorphous lesions that may present as burrows, pruritic papules, and inflammatory nodules. Bullous scabies (BS) is its rather rare subtype, mimicking bullous pemphigoid. We report a 15-year-old Chinese boy presenting with 1-month history of pruritic bullae on his penile skin, showing poor response to both topical steroids and systemic antihistamines, but cured by sulfur ointment alone. No recurrence occurred in the 5 years of follow-up. We also reviewed the published cases. Up to date, 44 cases, including the present, have been reported. Of them, 30 were male and 14 were female. The age range was from 1 to 89 years old, with a median age of 70.6 years. The bullous lesions may involve the arms, legs, trunk, genitals, feet, buttocks, thighs, neck, inguinal folds, and may even be generalized. Trunk and extremities are the most common involved locations. Facial or mucosa involvement had never been reported. The histological findings present as a subepidermal split with variable inflammatory infiltrate predominantly neutrophils, and eosinophilic spongiosis, or both. Eighteen of 32 patients showed positive deposition of linear-granular IgG or complement 3 alone or in various combinations, and five of 24 patients revealed circulating IgG. All the 40 cases with therapeutic details were cured by antiscabietic remedy. BS always involves the trunk and extremities. It has a predilection for elderlies and males. The treatments for BS are similar to those of classical scabies. © The American Society of Tropical Medicine and Hygiene.

Skin injuries were assessed in 560 imported and local cattle and water buffaloes at two livestock markets in Bangladesh. The body of each animal was divided into 11 anatomical regions, and abrasions, lacerations, penetrations, ulcerations, bleeding, swelling, hyperkeratosis and scars were recorded for each region. Among the 560 animals studied, 501 were found to have at least one injury. The prevalence of skin injuries was 89 per cent, with 84 per cent of the cattle and 99 per cent of the water buffaloes having obvious skin injuries. The most common types of injury were abrasions that were found in 73 per cent of the animals, followed by scars (50 per cent), and lacerations (41 per cent). Buffaloes had more abrasions (95 per cent), lacerations (57 per cent), swelling (15 per cent) and hyperkeratosis (32 per cent) compared with cattle, whereas scars (60 per cent) were more common in cattle (P<0.001). Within the 11 different anatomical regions, all types of injuries were present but in different proportions. The buttock region had a higher proportion of abrasions (36 per cent) followed by the hip, hindlimb and back regions. Penetration, ulceration, bleeding and swelling were present at lower frequencies in all regions. Causes for these injuries included rubbing against the inside wall of vehicles used for transportation and stock-handler abuse (59 per cent and 13 per cent, respectively). Buffaloes sustained more transport injuries than cattle, and the number of injuries was higher in imported than local animals.

In downhill alpine skiing, skiers often exceed speeds of 120 km h-1, with air resistance substantially affecting the overall race times. To date, studies on air resistance in alpine skiing have used wind tunnels and actual skiers to examine the relationship between the gliding posture and magnitude of drag and for the design of skiing equipment. However, these studies have not revealed the flow velocity distribution and vortex structure around the skier. In the present study, computational fluid dynamics are employed with the lattice Boltzmann method to derive the relationship between total drag and the flow velocity around a downhill skier in the full-tuck position. Furthermore, the flow around the downhill skier is visualised, and its vortex structure is examined. The results show that the total drag force in the downhill skier model is 27.0 N at a flow velocity of 15 m s-1, increasing to 185.8 N at 40 m s-1. From analysis of the drag distribution and the flow profile, the head, upper arms, lower legs, and thighs (including buttocks) are identified as the major sources of drag on a downhill skier. Based on these results, the design of suits and equipment for reducing the drag from each location should be the focus of research and development in ski equipment. This paper describes a pilot study that introduces undergraduate students of physics or engineering into this research field. The results of this study are easy to understand for undergraduate students.

Case report. We report a rare case that a ganglion cyst compressed the sciatic nerve and caused sciatica and claudication in a 51-year-old male. Sciatica and claudication commonly occurs in spinal stenosis. To our knowledge, only 4 cases have been reported on sciatica resulting from posterior ganglion cyst of hip. A 51-year-old male had a 2-month history of radiating pain on his right leg. He could only walk 20 to 30 m before stopping and standing to rest for 1 to 3 minutes. Interestingly, he was able to walk longer distances (about 200 m) when walking slowly in small steps, without any rest. He had been treated as a case of lumbar disc herniation, but conservative treatment was ineffective. On buttock examination, a round, hard, and fixative mass was palpated at the exit of the sciatic nerve. MR imaging of hip revealed a multilocular cystic mass located on the posterior aspect of the superior gemellus and obturator internus, compressing the sciatic nerve. On operation, we found that the cyst extended to the superior gemellus and the obturator internus, positioned right at the outlet of the sciatic nerve. At 18 months of follow-up, the patient continued to be symptom free. He returned to comprehensive physical activity with no limitations. For an extraspinal source, a direct compression on the sciatic nerve also resulted in sciatica and claudication. A meticulous physical examination is very important for the differential diagnosis of extraspinal sciatica from spinal sciatica.

Inability to predict postpartum hemorrhage: insights from Egyptian intervention data

PubMed Central

2011-01-01

Background Knowledge on how well we can predict primary postpartum hemorrhage (PPH) can help policy makers and health providers design current delivery protocols and PPH case management. The purpose of this paper is to identify risk factors and determine predictive probabilities of those risk factors for primary PPH among women expecting singleton vaginal deliveries in Egypt. Methods From a prospective cohort study, 2510 pregnant women were recruited over a six-month period in Egypt in 2004. PPH was defined as blood loss ≥ 500 ml. Measures of blood loss were made every 20 minutes for the first 4 hours after delivery using a calibrated under the buttocks drape. Using all variables available in the patients' charts, we divided them in ante-partum and intra-partum factors. We employed logistic regression to analyze socio-demographic, medical and past obstetric history, and labor and delivery outcomes as potential PPH risk factors. Post-model predicted probabilities were estimated using the identified risk factors. Results We found a total of 93 cases of primary PPH. In multivariate models, ante-partum hemoglobin, history of previous PPH, labor augmentation and prolonged labor were significantly associated with PPH. Post model probability estimates showed that even among women with three or more risk factors, PPH could only be predicted in 10% of the cases. Conclusions The predictive probability of ante-partum and intra-partum risk factors for PPH is very low. Prevention of PPH to all women is highly recommended. PMID:22123123

With the proliferation of dermal fillers in the aesthetic workplace have come instructions from various manufacturers regarding dermal placement. Determination of injection needle location in the dermis has in large part been based on physician expertise, product and needle familiarity, and patient-specific skin characteristics. An understanding of the precise depth of dermal structures may help practitioners improve injection specificity. Unlike other dermal fillers that suggest intradermal and deep dermal injection planes, a new hyaluronic acid with a cohesive polydensified matrix may be more appropriate for the superficial dermis because of its structure and its high degree of integration into the dermis. To that end, the authors designed a small study to quantify the depth of the superficial dermis by means of ultrasound and histology. Using ultrasound resources, the authors determined the depths of the epidermis, the dermis, and the reticular dermis in the buttocks of six patients; the authors then extrapolated the depth of the superficial reticular dermis. Histologic studies of two of the patients showed full integration of the product in the reticular dermis. Following determination of injection depths and filler integration, the authors describe a technique ("blanching") for injection of the cohesive polydensified matrix hyaluronic acid into the superficial dermis. At this time, blanching is appropriate only for injection of the cohesive polydensified matrix hyaluronic acid known as Belotero Balance in the United States, although it may have applications for other hyaluronic acid products outside of the United States.

This study was conducted to retrospectively evaluate a total of 4390 cases (1712 female, mean age: 25 years old; 2678 male, mean age: 35 years old) admitted to the rabies vaccine center of Giresun State Hospital, a province located at eastern Black-Sea region of Turkey, with the history of animal bite between the years of 2005-2009. It was determined that 74.5% of the cases were bitten by dogs, 22% by cats and 3.5% by wild animals and others. The most frequently bitten area was the lower extremities (n= 2678, 61%) (buttocks, legs and foot in order of decreasing frequency), followed by upper extremities (n= 1200, 27%) (hands, arms, head and neck area) and other areas (n=512, 11.6%) (back, abdomen, groin). According to the "Rabies Protection and Control Guidelines" of the Turkish Ministry of Health, 3210 cases (98.8%) were only vaccinated against rabies and 38 cases (1.2%) were both vaccinated and applied rabies antiserum according to the risk factors related to the suspected bite. Ten days follow-up of the suspected animal was recommended to 1142 (26%) cases and since no death were detected among these animals, no vaccination were applied. In conclusion, since this specific area with mountains and forests is suitable for the inhabitance of reservoir animals, risk groups such as workers in the forest should receive pre-exposure prophylaxis and specific precautions should be undertaken for the vaccination and/or care of dogs for effective rabies control.

[Pontomedullary lacerations and concomitant injuries: a review of possible underlying mechanisms].

Anatomically, brainstem is constituted of medulla oblongata, pons and mesencephalon. Traumatic lesions of brainstem most commonly occur on pontomedullary junction. There are several possible mechanisms of pontomedullary lacerations. The first mechanism includes impact to the chin, with or without a skull base fracture, and most often leads to this fatal injury, due to impact force transmission through the jawbone and temporomandibular joint. The second mechanism includes lateral and posterior head impacts with subsequent hinge fractures, where occurrence of pontomedullary lacerations in these cases may depend on the energy of impact, as well as on the exact position of the fracture line, but less so on the head's movement. The third mechanism includes frontoposterior hyperextension of the head, due to frontal impact, concomitant with fractures or dislocations of upper spine. In the fourth mechanism, there is an absence of direct impact to the head, due to the indirect force of action after feet or buttocks-first impact. Most of these cases are accompanied by ring fractures as well. In situations such as these, the impact force is transmitted up the spinal column and upper vertebrae, and telescopically intruded into the skull, causing brainstem laceration. The jawbone and other facial bones can act as shock absorbers, and their fracture could diminish the energy transfer towards the skull and protect the brain and brainstem from injury. In all the cases with pontomedullary laceration posterior neck dissection should be performed during the autopsy, since upper spine injuries are often associated with this type of injury.

OBJECTIVE: To develop guidelines for performing an initial skeletal survey (SS) for children <24 months of age presenting with bruising in the hospital setting, combining available evidence with expert opinion. METHODS: Applying the Rand/UCLA Appropriateness Method, a multispecialty panel of 10 experts relied on evidence from the literature and their own clinical expertise in rating the appropriateness of performing SS for 198 clinical scenarios characterizing children <24 months old with bruising. After a moderated discussion of initial ratings, the scenarios were revised. Panelists re-rated SS appropriateness for 219 revised scenarios. For the 136 clinical scenarios in which SS was deemed appropriate, the panel finally assessed the necessity of SS. RESULTS: Panelists agreed that SS is “appropriate” for 62% (136/219) of scenarios, and “inappropriate” for children ≥12 months old with nonpatterned bruising on bony prominences. Panelists agreed that SS is “necessary” for 95% (129/136) of the appropriate scenarios. SS was deemed necessary for infants <6 months old regardless of bruise location, with rare exceptions, but the necessity of SS in older children depends on bruise location. According to the panelists, bruising on the cheek, eye area, ear, neck, upper arm, upper leg, hand, foot, torso, buttock, or genital area necessitates SS in children <12 months. CONCLUSIONS: The appropriateness and necessity of SS in children presenting for care to the hospital setting with bruising, as determined by a diverse panel of experts, depends on age of the child and location of bruising.

Cellulite treatment: evidence and ethics, brief history, and emphasis on current practices including liposuction

de Riese, Cornelia

2005-04-01

According to Taber's Cyclopedic Medical Dictionary "cellulite" is defined as: "a non-technical term for subcutaneous deposits of fat, especially in the buttocks, legs, and thighs." These deposits result in puckered, dimply skin and they are a cause for major aesthetic concerns in affected patients. The etiology of this condition is still unclear. Female predilection is witnessed in clinical practice as it is reported in the literature. It remains a subject for further studies whether it is a structural problem of connective tissue or as suggested probably related to hormonal causes. Magnetic resonance imaging may provide some answers to these questions. Not knowing what is causing this nuisance makes it almost impossible to treat. No wonder that there is little scientific validation to support any of the many treatments that are advertised on the Internet or in women's magazines. This review focuses on mechanical and microinvasive interventions that claim to alleviate "cellulite": lipoplasty, liposcultpure, liposuction, subcision, and laser. Among the parameters analyzed are the proposed modes of action of these techniques as well as adverse events and complications that may occur. Of special interest will be the evidence that backs these procedures. Extracting reliable data is hampered by methodical problems with the design of most of the published trials. In essence, at this time there is no "cure" for cellulite. Safe treatment recommendations are related to healthy life style choices that include toning exercises, dietary changes, and weight loss.

The prognostic value of detailed anatomic site and ultraviolet radiation (UVR) exposure patterns has not been fully determined in cutaneous melanoma. Thus, we reviewed medical records for detailed site in a population-based retrospective Swedish patient cohort diagnosed with primary invasive melanoma 1976-2003 (n = 5,973). We followed the patients from date of diagnosis until death, emigration or December 31 st 2013, and evaluated melanoma-specific survival by subsite in a multivariable regression model adjusting for established prognostic factors. We found that melanoma on chronic UVR exposure sites (face, dorsum of hands; adjusted HR 0.6; CI 0.4-0.7) and moderately intermittent UVR sites (lateral arms, lower legs, dorsum of feet; HR 0.7; CI 0.6-0.8) were associated with a favorable prognosis compared with highly intermittent sites (chest, back, neck, shoulders and thighs). Further, melanoma on poorly visible skin sites upon self-examination (scalp, retroauricular area, back, posterior upper arms and thighs, buttocks, pubic area; HR 1.3; CI 1.1-1.5) had a worse prognosis than those on easily visible sites (face, chest, abdomen, anterior upper arms and thighs, lower arms and legs, dorsum of hands and feet, palms). In conclusion, highly intermittent UVR exposure sites and poor skin visibility presumably correlate with reduced melanoma survival, independent of established tumor characteristics. A limitation of the study was the lack of information on actual individual UVR exposure. © 2017 UICC.

Outbreak of Mycobacterium tuberculosis infections associated with acupuncture has not been reported. Thirteen patients with a painful swollen lump were referred to our hospital. The index patient received acupuncture and paraspinal muscular injection at a local acupuncture clinic in April 2011 and was diagnosed with M. tuberculosis 1 month later. From May 2011 to August 2011, 12 more patients with a swollen lump on the nuchal region or in the lower back or the buttocks region were referred to our hospital. Tuberculin skin test (TST), T-SPOT.TB, acid-fast stain, M. tuberculosis culture, chest radiograph, and lump magnetic resonance imaging (MRI) were performed and the patients were diagnosed with tuberculous abscess of the lump. All 13 patients received intramuscular injection at the paraspinal muscle by two acupuncturists at a local clinic and reported a swollen lump at the injection site. The needles and syringes were reused after autoclave sterilization. The TST was positive in all patients. Twelve patients had positive acid-fast stains. Mycobacterial cultures of abscess specimens were positive in all 13 patients. T-SPOT.TB tests were positive in all patients who underwent the test. The lesions and biopsies were subjected to polymerase chain reaction (PCR) and gene sequencing by the Disease Control Center of Zhejiang Province, China and the causative agent was identified as M. tuberculosis, Beijing type. In conclusion, physicians should consider the possibility of mycobacterial infections, apart from other bacterial agents, in patients with a swollen paraspinal lump following intramuscular injection.

Germ cell tumors are known to arise in the central nervous system, usually in the intracranial regions. However, primary spinal mixed germ cell tumors are extremely rare. This is the first reported case of intratumoral hemorrhage because of a primary spinal mixed germ cell tumor consisting of germinoma and immature teratoma in the conus medullaris of an adult patient that presented with rapid changes on magnetic resonance image (MRI). We report this rare case and discuss the clinical manifestations of an intramedullary spinal mixed germ cell tumor in adult. A case report. A 42-year-old woman experienced buttock numbness, and a spinal cord tumor was observed on the conus medullaris on MRI. The patient was scheduled for an operation in 1 month, but she developed sudden-onset neurologic deterioration. Rapid progression of the tumor was observed on follow-up MRI. The tumor was removed by emergency surgery and was identified as a primary mixed germinoma and immature teratoma. The patient received adjuvant chemotherapy and radiotherapy after gross total resection. The neurologic deficit of the patient was relieved, and recurrence of the tumor was not observed 26 months after the surgery. We present this rare case and emphasize the necessity of precise diagnosis and early treatment of primary spinal germ cell tumor. Close observation on MRI is required after surgery, and adjuvant chemotherapy and radiotherapy should be considered according to the pathologic features. Copyright © 2013 Elsevier Inc.

Boomerang pattern correction of gynecomastia.

Hurwitz, Dennis J

2015-02-01

After excess skin and fat are removed, a body-lift suture advances skin and suspends ptotic breasts, the mons pubis, and buttocks. For women, the lift includes sculpturing adiposity. While some excess fat may need removal, muscular men should receive a deliberate effort to achieve generalized tight skin closure to reveal superficial muscular bulk. For skin to be tightly bound to muscle, the excess needs to be removed both horizontally and vertically. To aesthetically accomplish that goal, a series of oblique elliptical excisions have been designed. Twenty-four consecutive patients received boomerang pattern correction of gynecomastia. In the last 12 patients, a J torsoplasty extension replaced the transverse upper body lift. Indirect undermining and the opposing force of a simultaneous abdominoplasty obliterate the inframammary fold. To complete effacement of the entire torso in 11 patients, an abdominoplasty was extended by oblique excisions over bulging flanks. Satisfactory improvement was observed in all 24 boomerang cases. A disgruntled patient was displeased with distorted nipples after revision surgery. Scar maturation in the chest is lengthy, with scars taking years to flatten and fade. Complications were limited and no major revisions were needed. In selected patients, comprehensive body contouring surgery consists of a boomerang correction of gynecomastia. J torsoplasty with an abdominoplasty and oblique excisions of the flanks has proven to be a practical means to achieve aesthetic goals. Gender-specific body lift surgery that goes far beyond the treatment of gynecomastia best serves the muscular male patient after massive weight loss. Therapeutic, IV.

Scrub typhus is endemic in Thailand. Of the 495 patients with acute undifferentiated fever studied in Maharat Nakhon Ratchasima Hospital, Nakhon Ratchasima, Thailand, from June 1, 2011, to December 31, 2012, 146 patients (29.5%) had confirmed scrub typhus. The majority of cases were male, farmers, with the mean (±standard deviation) age of 54.1 ± 15.2 years. A total of 59 patients (40.4%) had eschar lesion. The commonest sites for an eschar in male patients were the perineum, inguinal, and buttock area; whereas in females, it was the head and neck area. Abnormal electrocardiogram was found in 39 of 79 patients (49.4%) with sinus tachycardia being the most frequent finding (17, 21.5%). A total of 73 patients (50%) had at least one complication. Myocarditis was the cause of complete heart block in a scrub typhus patient, and he fully recovered after receiving intravenous chloramphenicol treatment. The case fatality rate was 6.2% (nine deaths).The independent predictors for fatal outcome were age over 65 years (odds ratio [OR] = 14.49, 95% confidence interval [CI] = 1.26-166.44, P = 0.03), acute kidney injury (OR = 12.75, 95% CI = 1.77-92.07, P = 0.01), and hyperbilirubinemia (OR = 24.82, 95% CI = 2.12-286.61, P = 0.01). Early diagnosis and prompt appropriate treatment can improve the patient's outcome. © The American Society of Tropical Medicine and Hygiene.

'Telangiectatic' change, which contains a large fluid hemorrhagic component, occurs in a variety of high-grade soft tissue sarcomas. In a retrospective database review, we identified 20 consecutive patients (3%) with 'telangiectatic' change in soft tissue sarcomas. Tumors were located in the thigh (55%), shoulder (15%), calf (15%), upper arm (10%), and buttock in one patient. All 20 tumors were high grade. Histological diagnoses were MFH (40%), leiomyosarcoma (15%), synovial sarcoma (10%), and one each of seven other sarcomas (35%). Tumor size was often large-more than 10 cm (35%), between 5 and 10 cm (60%), and less than 5 cm in one case. A history of contusion to the tumor site followed by swelling was recorded in 30% of patients and 80% presented with a painful mass. On MRI imaging, 60% of tumors appeared to contain more than 50% blood, 50% had a hemosiderin-laden rim, and 55% had well-defined tumor nodules within the wall of the hematoma. Limb-sparing surgery was carried out in 90% of patients, the other 10% underwent primary amputation. The 5-year, event-free survival rate was 30%. Of the patients, 15% presented initially with metastatic disease; in 53%, it developed within 2 years of diagnosis. The overall local recurrence rate was 30%. Telangiectatic transformation in soft tissue sarcomas is a rare feature of aggressive high-grade soft tissue sarcomas and is unique in its clinical presentation, MRI characteristics, pathological pattern, and a tendency for a worse-off prognosis.

Hidradenitis suppurativa (HS) is a chronic relapsing inflammatory skin disease with multiple treatment options that have been used with mixed results. To evaluate the effectiveness, safety and tolerability of intralesional photodynamic therapy (I-PDT) in the management of HS. Also, to assess the effect of this technique on the different areas treated. Case series of 38 HS patients treated with I-PDT between 2011-2015 following a standardized protocol to assess response at the treated areas RESULTS: 29 patients achieved a complete response, while persistence was noted on 8 cases and only 1 suffered a recurrence. Difference between basal (median 28.5) and final (0) Hidradenitis Severity Score showed a significant reduction of 24.5 points (p<0.001, 95% OR 19.5-31). Basal (median 10) and final (1) Dermatology Life Quality Index scores reached a reduction of 10 points (p<0.001, 95%OR 8-12). Complete response was achieved in 68.2% of armpits, 88.5% of groins, 88.9% of buttocks and 100% of other locations. 18 out of 38 patients needed only a session to achieve a complete response, while maintaining a good tolerability. We believe that I-PDT might be an alternative treatment option for localized HS lesions, achieving a high rate of remission with an adequate maintenance of response i and few complications.

2016-12-23

Cutaneous lesions of sarcoidosis present with various manifestations including specific and non-specific cutaneous lesions. Ichthyosiform sarcoidosis is a rare form of cutaneous sarcoidosis, presenting with asymptomatic, adherent, polygonal scales, mainly appearing on the lower limbs.  Ichthyosiform sarcoidosis has a predilection for dark-skinned races, and cases affecting Japanese patients have rarely been reported in English literature.  We herein describe three Japanese cases of ichthyosiform sarcoidosis on the lower limbs. All of the patients were female, with an age range of 57-69 years old.  Histologically, sarcoidal granulomas were located in the mid- to lower dermis.  All cases had scar sarcoidosis on the knees.  Furthermore, Case 1 presented with papular sarcoidosis on the back, and Case 3 presented with subcutaneous nodules on the buttock as well as erythema nodosum-like lesions on the lower legs.  All patients had lung sarcoidosis, but ocular sarcoidosis was seen in only Case 2. Case 3 showed Heerfordt syndrome with facial nerve paralysis. Histological features showed that the granular layers were scarcely detected in the overlying epidermis; however, filaggrin expression was not decreased.  Sarcoidal granulomas accumulated around the sweat glands in one case, whereas those features were not detected in the other two cases. In conclusion, ichthyosiform cutaneous sarcoidosis may be overlooked or misdiagnosed as xerotic dry skin which is frequently found in elderly people, and ichthyosiform cutaneous lesions may be more prevalent than previously estimated.

Perineal tap water burns in the elderly: at what cost?

Burn injuries are expensive to treat. Burn injuries have been found to be difficult to treat in elderly patients than their younger counterparts. This is likely to result in higher financial burden on the healthcare system; however, no population-specific study has been conducted to ascertain the inpatient treatment costs of elderly patients with hot tap water burns. Six elderly patients (75-92 years) were admitted for tap water burns at Concord Hospital during 2010. All costs incurred during their hospitalization were followed prospectively, and were apportioned into 'direct' and 'indirect' costs. Direct costs encompassed directly measurable costs, such as consumables used on the ward or in theatres, and indirect costs included hospital overheads, such as bed and theatre costs. Three males and three females admitted with burns to the buttocks, legs or feet. Total burn surface area (TBSA) ranged from 9-21% (mean 12.8%). Length of stay ranged from 26-98 days (mean 46 days). One patient died, and four required surgical management or grafting. Total inpatient costs ranged from $69 782.33 to $254 652.70 per patient (mean $122 800.20, standard deviation $67 484.46). TBSA was directly correlated with length of stay (P < 0.01) and total cost (P < 0.01). Hot water burns among the elderly are associated with high treatment costs, which are proportional to the size of the burn. The cost of treating this cohort is higher than previously reported in a general Australian burn cohort. © 2016 Royal Australasian College of Surgeons.

2016-01-01

Scabies is a common contagious cutaneous disease and usually affects the young, characterized by polymorphous lesions that may present as burrows, pruritic papules, and inflammatory nodules. Bullous scabies (BS) is its rather rare subtype, mimicking bullous pemphigoid. We report a 15-year-old Chinese boy presenting with 1-month history of pruritic bullae on his penile skin, showing poor response to both topical steroids and systemic antihistamines, but cured by sulfur ointment alone. No recurrence occurred in the 5 years of follow-up. We also reviewed the published cases. Up to date, 44 cases, including the present, have been reported. Of them, 30 were male and 14 were female. The age range was from 1 to 89 years old, with a median age of 70.6 years. The bullous lesions may involve the arms, legs, trunk, genitals, feet, buttocks, thighs, neck, inguinal folds, and may even be generalized. Trunk and extremities are the most common involved locations. Facial or mucosa involvement had never been reported. The histological findings present as a subepidermal split with variable inflammatory infiltrate predominantly neutrophils, and eosinophilic spongiosis, or both. Eighteen of 32 patients showed positive deposition of linear-granular IgG or complement 3 alone or in various combinations, and five of 24 patients revealed circulating IgG. All the 40 cases with therapeutic details were cured by antiscabietic remedy. BS always involves the trunk and extremities. It has a predilection for elderlies and males. The treatments for BS are similar to those of classical scabies. PMID:27402514

International estimates of the incidence of non-accidental burns (NAB) in children admitted to burn centres vary from 1% to 25%. Hardly any data about Dutch figures exist. The aim of this study was to evaluate the incidence, treatment and outcome of burns due to suspected child abuse in paediatric burns. We described the process of care and outcome, including the accuracy of the SPUTOVAMO screening tool and examined child, burn and treatment characteristics related to suspicions of child abuse or neglect. A retrospective study was conducted in children aged 0-17 years with a primary admission after burn injuries to the burn centre Rotterdam in the period 2009-2013. Data on patient, injury and treatment characteristics were collected, using the Dutch Burn Repository R3. In addition, medical records were reviewed. In 498 paediatric admissions, suspected child abuse or neglect was present in 43 children (9%). 442 screening questionnaires (89%) were completed. In 52 out of 442 questionnaires (12%) the completed SPUTOVAMO had one or more positive signs. Significant independent predictors for suspected child abuse were burns in the genital area or buttocks (OR=3.29; CI: 143-7.55) and a low socio-economic status (OR=2.52; 95%CI: 1.30-4.90). The incidence of suspected child abuse indicating generation of additional support in our population is comparable to studies with a similar design in other countries.

Morbid obesity develops as a result of hyperphagia and compulsive eating behavior in patients with Prader-Willi syndrome (PWS), if caloric intake is not rigorously controlled. PWS-specific centile curves for adiposity indices constructed in the past were based on clinically diagnosed patients. With the advent of molecular genetic methods, allowing for an unequivocal diagnosis, new PWS curves based exclusively on molecularly diagnosed patients are becoming available, eliminating a potential diagnostic bias. To compare fat distribution in molecularly confirmed German PWS patients to that of clinically diagnosed American PWS patients and a healthy reference population. Cross-sectional anthropometric study. One hundred German patients (49 F) with molecularly confirmed PWS (age: <30 y). Triceps (subscapular) skinfold thickness, waist and hip circumference. Skinfold thickness was massively elevated in the majority of the molecularly confirmed German PWS patients compared to a healthy reference population. Whereas triceps skinfold thickness was in good agreement with American PWS patients, subscapular skinfold thickness in German girls rose earlier than in American PWS girls, indicating possible differences between caloric intake or the proportion of patients entering puberty spontaneously. Waist circumference and waist-hip ratio (n=89) were elevated in a relative small proportion of patients only and did not reflect lower abdominal fat. This may be due to the peculiar shape of many patients with a typical fat accumulation around the buttocks. In addition to body mass index, use of skinfold thickness is recommended for follow-up of dietary interventions in PWS.

Photoaging accounts for most age-related changes in skin appearance. It has been suggested that both astaxanthin, a potent antioxidant, and collagen hydrolysate can be used as antiaging modalities in photoaged skin. However, there is no clinical study using astaxanthin combined with collagen hydrolysate. We investigated the effects of using a combination of dietary astaxanthin and collagen hydrolysate supplementation on moderately photoaged skin in humans. A total of 44 healthy subjects were recruited and treated with astaxanthin (2 mg/day) combined with collagen hydrolysate (3 g/day) or placebos, which were identical in appearance and taste to the active supplementation for 12 weeks. The elasticity and hydration properties of facial skin were evaluated using noninvasive objective devices. In addition, we also evaluated the expression of procollagen type I, fibrillin-1, matrix metalloproteinase-1 (MMP-1) and -12, and ultraviolet (UV)-induced DNA damage in artificially UV-irradiated buttock skin before and after treatment. The supplement group showed significant improvements in skin elasticity and transepidermal water loss in photoaged facial skin after 12 weeks compared with the placebo group. In the supplement group, expression of procollagen type I mRNA increased and expression of MMP-1 and -12 mRNA decreased compared with those in the placebo group. In contrast, there was no significant difference in UV-induced DNA damage between groups. These results demonstrate that dietary astaxanthin combined with collagen hydrolysate can improve elasticity and barrier integrity in photoaged human facial skin, and such treatment is well tolerated.

There are many types of treatments and recommendations for restoring back deformities depending on doctors' knowledge and opinions. The purpose of the exercises is to reduce pain and to ensure stability of the lower trunk by toning the abdominal muscles, buttocks and hamstrings. Given the duration of flares and relapses rate, it is important to apply an efficient and lasting treatment. To evaluate the effects of 8 weeks of William's training on flexibility of lumbosacral muscles and lumbar angle in females with Hyperlordosis. Forty female students with lumbar lordosis more than normal degrees (Hyperlordotic) that were randomly divided into exercise and control groups were selected as the study sample. The lumbar lordosis was measured using a flexible ruler, flexibility of hamstring muscles was measured with the active knee extension test, the hip flexor muscles strength was measured using Thomas test, the lumbar muscles flexibility measures by Schober test, abdominal muscles strength measured by Sit-Up test and back pain was measured using McGill's Visual Analogue Scales (VAS) questionnaire. Data were compared before and post-test using independent and paired t-testes. Results showed that 8 weeks of William's exercise led to significant decreases in lumbar angle and back pain, increases in flexibility of hamstring muscles, hip flexor muscles flexibility, lumbar extensor muscles flexibility and abdominal muscles strength. The findings show that William's corrective training can be considered as a useful and valid method for restoring and refining back deformities like as accentuated back-arc and became wreaked muscles' performance in lumbar areas.

Previous studies have shown an association between spanking and child physical abuse. However, the relationship between more frequent and severe corporal punishment and abuse remains unknown. The objective of this study was to examine the associations between reported spanking, spanking frequency, or spanking with an object and the odds of physical abuse in a representative sample of mothers from North and South Carolina. This study is a cross-sectional, anonymous telephone survey of adult mothers with children aged<18 years living in the Carolinas in 2002. The analysis was conducted in 2007. Survey responses were used to determine the association between corporal punishment (spanking, spanking frequency, and spanking with an object) and an index of harsh physical punishment consistent with physical abuse (beating, burning, kicking, hitting with an object somewhere other than the buttocks, or shaking a child aged<2 years). Mothers who report that the child was spanked are 2.7 (95% CI=1.2, 6.3) times more likely to report abuse. Increases in the frequency of reported spanking in the last year are also associated with increased odds of abuse (OR=1.03, 95% CI=1.01, 1.06). Mothers reporting spanking with an object are at markedly increased odds of reporting abuse (OR=8.9, 95% CI=4.1, 19.6). Although reported spanking increases the odds of reported physical abuse, the relationship between the reported hitting of a child with an object and reported abuse is much stronger. Reduction in this form of discipline through media, educational, and legislative efforts may reduce child physical abuse.

Study Design Multicenter prospective study with a crossover design. Purpose The objective of this study is to compare the efficacy of limaprost alfadex (LP) and elcatonin (EL) for lumbar spinal stenosis (LSS) patients with concurrent osteoporosis. Overview of Literature It has been increasingly important to improve quality of life by establishing appropriate conservative treatments for LSS patients with concurrent osteoporosis who will presumably continue to increase due to the percentage of the aging elevations, however there is no prospective study. Methods A total of 19 patients with LSS and concurrent osteoporosis were enrolled in this study. The patients were divided into two groups and compared using a crossover design. The Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) and short-form (SF)-8 health survey scale were used for clinical evaluations. Results There was a significant improvement of buttock-leg pain and numbness in the EL group. A significant improvement of impaired walking function was noted for the LP group according to the JOABPEQ while the rest of the items in the JOABPEQ showed no significant differences. The SF-8 health survey revealed that somatic pains and physical summary scores in the EL group and physical functioning and physical summary scores in the LP group tended to improve but not to any statistically significant extents. Conclusions Concomitant uses of EL may be useful in patients who do not respond satisfactorily to the treatments of LP for 6-8 weeks. PMID:25187864

Medico legal autopsies can be valuable sources of information about the distribution of causes of reported deaths, particularly in homicidal cases. The present study provides information regarding the homicidal deaths due to firearm injuries in the district of Peshawar, NWFP, Pakistan. This descriptive study was conducted over the period of the year 2004. Data were collected from the autopsy records of the Department of Forensic Medicine, Khyber Medical College Peshawar and included all reported unnatural deaths from urban and rural areas of district Peshawar on whom autopsies were conducted in the department. Homicidal deaths constituted 77.7% (492/633) of all autopsies for the year 2004. Of 492 homicidal deaths, a vast majority of 452 (91.87%) were caused by firearm injuries. Among these, the male to female ratio was 5.5:1. The most common firearm weapon (418/452, 92.5%) were high velocity rifled weapons (Kalashnikov, rifles, pistols), followed by low velocity rifled weapons (18/452, 3.98%) and shotguns (16/452, 3.54%). A total of 956 injuries were found in various body areas, giving an average of over two injuries per person. The head, face and neck sustained the highest injuries (257, 26.9%), followed by the chest (248, 25.9%) and abdomen (149, 15.6%); the extremities, buttocks and genitalia together sustained 302 (31.6%) injuries. The vast majority of reported homicides in Peshawar are caused by firearm injuries, which bring up issues related to possession of firearms and changes in cultural attitudes towards use of firearms, if a decrease in firearm-related homicides is desired.

One of the aims of a subcutaneous (SC) injection is to avoid intradermal or intramuscular injections. Pen systems are an alternative solution to single-use syringes and have become standard for example diabetes therapy. Shorter and smaller needles minimize pain and the risk of intramuscular injections. The thickness of subcutaneous adipose tissue (SCAT) varies with position and with body mass index (BMI). The aim of this study was the creation of a map of SCAT thickness at typical spots for SC self-injection. MRI scans of 116 prospectively enroled volunteers (56 men and 60 women) were analysed. SCAT thickness was determined at 17 spots over the abdominal wall, left thigh, buttocks and upper arm, typical sites for subcutaneous self-injection. SCAT thicknesses were correlated with BMI and waist-to-hip ratio (WHR), and a linear curve fit was performed. The best fitting linear functions for the prediction of the SCAT thickness dependent on BMI and WHR were derived. Correlations between SCAT and BMI were higher (0·67-0·21) than with WHR (-0·67 to 0·09). In women, correlation coefficients between SCAT data at the abdomen and BMI/WHR were higher than in men. On the other hand, data showed better correlations at the extremities in men. The data, with correlation between BMI and fat thickness at different injection sites in relation to gender, provide guidance in selecting an adequate pen needle length for deep and safe subcutaneous self-injection. WHR was a much weaker predictor when compared to BMI. © 2011 Blackwell Publishing Ltd.

Hidradenitis suppurativa: A practical review of possible medical treatments based on over 350 hidradenitis patients.

Scheinfeld, Noah

2013-04-15

Hidradenitis suppurativa (HS), a pathological follicular disease, impacts patients' lives profoundly. HS most commonly involves cutaneous intertriginous areas, such as the axilla, inner thighs, groin and buttocks, and pendulous breasts, but can appear on any follicular skin. Protean, HS manifests with variations of abscesses, folliculitis, pyogenic granulomas, scars (oval honeycombed), comedones, tracts, fistulas, and keloids. The pathophysiology might involve both defects of the innate follicular immunity and overreaction to coagulase negative Staphylococcus. Treatment depends on the morphology, extent, severity, and duration. Topical clindamycin and dapsone are often adequate for treating mild HS. For Stage 1 and 2 HS, first line treatment combines rifampin with either oral clindamycin or minocycline. Other HS treatments include: fluoroquinolones with metronidazole and rifampin, oral dapsone, zinc, acitretin, hormone blockers (oral contraceptive pills, spironolactone, finasteride, and dutasteride), and oral prednisone. For severe HS, cyclosporine, adalimumab, or infliximab (used at double psoriatic doses) and intravenous carbapenems or cephalosporins are often required. Isotretinoin, etanercept, isoniazid, lymecycline, sulfasalazine, methotrexate, metformin, colchicine, clarithromycin, IVIG, and thalidomide are less favored treatments. The role of botulinum toxin is uncertain. The most important life style modification is weight loss. De-roofing fluctuant nodules and injection of intralesional corticosteroids ameliorates the disease and perhaps, if done at regular intervals, improves HS more permanently. Surgical excision and CO2 laser ablation are more definitive treatments. The 1064 nm laser for hair removal aids in the treatment of HS. This article centers on medical therapies and will only passingly mention surgical and laser treatments. This article summarizes my treatment experience with over 350 HS patients.

Experimental study of the in vivo kinetics of tanning in human skin has been limited by the difficulties in measuring changes in melanin pigmentation independent of the ultravioletinduced changes in erythema. The present study attempted to experimentally circumvent this issue. We have studied erythemal and tanning responses following a single exposure to a range of doses of ultraviolet B irradiation on the buttock and the lower back in 98 subjects. Erythema was assessed using reflectance techniques at 24 h and tanning measured as the L* spectrophotometric score at 7 days following noradrenaline iontophoresis. We show that dose (P < 0.0001), body site (P < 0.0001), skin colour (P < 0.0001), ancestry (P = 0.0074), phototype (P = 0.0019) and sex (P = 0.04) are all independent predictors of erythema. Quantitative estimates of the effects of these variables are reported, but the effects of ancestry and phototype do not appear solely explainable in terms of L* score. Dose (P < 0.0001), body site (P < 0.0001) and skin colour (P = 0.0365) or, as an alternative to skin colour, skin type (P = 0.0193) predict tanning, with those with lighter skin tanning slightly more to a defined UVB dose. If erythema is factored into the regression, then only dose and body site remain significant predictors of tanning: therefore neither phototype nor pigmentary factors, such as baseline skin colour, or eye or hair colour, predict change in skin colour to a unit erythemal response.

Knee pain is extremely common among the elderly, particularly women. Hence, there is an urgent need for applicable community-based intervention models for halting the progression of knee pain and related disabilities in elderly women. We aimed to assess the efficacy of home-visit physiotherapy as a new intervention model. This non-randomized 5-month-long controlled trial enrolled elderly community-dwelling women (aged 60-83 years) with mild knee pain. The intervention consisted of two home visits by a physiotherapist, with instructions on routinely performing muscle-strengthening exercises at home and implementing simple environmental modifications when necessary. Outcome measures were assessed at baseline and 5 months later. The primary outcomes were measured as the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and a newly devised seiza-style sitting score. People in Japan, especially elderly women, are accustomed to seiza-style sitting that involves kneeling on one's lower legs while resting the buttocks on the heels. The secondary outcomes included quadriceps isometric strength, knee alignment in the frontal and sagittal planes, and passive knee extension range. Forty-two subjects (20 in the intervention group and 22 in the control group) completed the study. At baseline, characteristics and the primary outcomes did not significantly differ between the 2 groups. At 5 months, the primary outcomes improved significantly in the intervention group. Estimated differences in the change from baseline for each outcome between the 2 groups were computed, adjusting for outcome variables imbalanced at baseline. Even after the adjustment, the home-visit physiotherapy regimen provides favorable improvement in the seiza-style sitting score.

An 86-year-old woman was found dead lying on her back on the floor of an unkempt kitchen. She had last been seen four days before. Her dress was pulled up and she was not wearing underpants. The house was noted to be in "disarray" with papers covering most surfaces and the floor. Rubbish was piled up against one of the doors. At autopsy the major findings were of a fractured left neck of femur, fresh pressure areas over her right buttock, Wischnewski spots of the stomach and foci of pancreatic necrosis, in keeping with hypothermia. No significant underlying organic diseases were identified and there was no other evidence of trauma. Death was due to hypothermia complicating immobility from a fractured neck of femur. This case confirms the vulnerability of frail, elderly and socially-isolated individuals to death from hypothermia if a significant illness or injury occurs. Additional risk factors for hypothermia are also illustrated in this case that involve inadequate housing construction with absent insulation and window double glazing. The approach to hypothermic deaths should, therefore, include checking for these features as well as measuring room and environmental temperatures, evaluating the type and quality of heating and the nature of the floor and its coverings, Given the ageing population in many Western countries, increasing social isolation of the elderly, cost of fuel and electricity, and lack of energy efficient housing, this type of death may become an increasingly witnessed occurrence during the colder months of the year.

Management of lumbar spinal stenosis.

PubMed

Lurie, Jon; Tomkins-Lane, Christy

2016-01-04

Lumbar spinal stenosis (LSS) affects more than 200,000 adults in the United States, resulting in substantial pain and disability. It is the most common reason for spinal surgery in patients over 65 years. Lumbar spinal stenosis is a clinical syndrome of pain in the buttocks or lower extremities, with or without back pain. It is associated with reduced space available for the neural and vascular elements of the lumbar spine. The condition is often exacerbated by standing, walking, or lumbar extension and relieved by forward flexion, sitting, or recumbency. Clinical care and research into lumbar spinal stenosis is complicated by the heterogeneity of the condition, the lack of standard criteria for diagnosis and inclusion in studies, and high rates of anatomic stenosis on imaging studies in older people who are completely asymptomatic. The options for non-surgical management include drugs, physiotherapy, spinal injections, lifestyle modification, and multidisciplinary rehabilitation. However, few high quality randomized trials have looked at conservative management. A systematic review concluded that there is insufficient evidence to recommend any specific type of non-surgical treatment. Several different surgical procedures are used to treat patients who do not improve with non-operative therapies. Given that rapid deterioration is rare and that symptoms often wax and wane or gradually improve, surgery is almost always elective and considered only if sufficiently bothersome symptoms persist despite trials of less invasive interventions. Outcomes (leg pain and disability) seem to be better for surgery than for non-operative treatment, but the evidence is heterogeneous and often of limited quality. © BMJ Publishing Group Ltd 2015.

Despite of the widespread use of 180-degree propeller flaps in the field of soft tissue reconstruction, less information are available in the current literature to standardize the use of propeller flaps with reduced degrees of rotation.The authors report their experience with propeller flaps with reduced rotational angles reviewing clinical applications and outcomes of the technique in a series of 40 consecutive reconstructions. Forty elective defects of various etiologies located in different regions of the body (head and neck, trunk, buttocks and perineum, extremities) were reconstructed with less than 180 degrees rotated propeller flaps. The technique was applied to patients presenting with a strong audible perforator detected in close proximity to the wound and the defect located in a position adjacent to the axis of the chosen perforasome. Defect size ranged from 2 × 2 to 15 × 9 cm. Flap dimensions ranged from 5 × 2 to 21 × 10 cm. The flaps were based on 1 (34) or 2 (6) perforators and were mobilized with an angle of rotation of 45, 90, and 135 degrees in 7, 24, and 9 patients, respectively. Mean operative time was 105 minutes. All flaps survived postoperatively. In only 4 cases (10%) partial flap necrosis was registered. All flaps achieved adequate and durable reconstruction with excellent contour, with a follow-up ranging between 6 months and 2 years. Propeller flaps with reduced rotational angles represent a safe and versatile option to reconstruct soft tissues defects at different anatomical sites.

AIM: We sought to evaluate musculoskeletal discomfort and mental and physical fatigue in the call-center workers of an airline company before and after a supervised exercise program compared with rest breaks during the work shift. INTRODUCTION: This was a longitudinal pilot study conducted in a flight-booking call-center for an airline in São Paulo, Brazil. Occupational health activities are recommended to decrease the negative effects of the call-center working conditions. In practice, exercise programs are commonly recommended for computer workers, but their effects have not been studied in call-center operators. METHODS: Sixty-four call-center operators participated in this study. Thirty-two subjects were placed into the experimental group and attended a 10-min daily exercise session for 2 months. Conversely, 32 participants were placed into the control group and took a 10-min daily rest break during the same period. Each subject was evaluated once a week by means of the Corlett-Bishop body map with a visual analog discomfort scale and the Chalder fatigue questionnaire. RESULTS: Musculoskeletal discomfort decreased in both groups, but the reduction was only statistically significant for the spine and buttocks (p=0.04) and the sum of the segments (p=0.01) in the experimental group. In addition, the experimental group showed significant differences in the level of mental fatigue, especially in questions related to memory Rienzo, #181ff and tiredness (p=0.001). CONCLUSIONS: Our preliminary results demonstrate that appropriately designed and supervised exercise programs may be more efficient than rest breaks in decreasing discomfort and fatigue levels in call-center operators.

Hand, foot, and mouth disease (HFMD) is caused by human enteroviruses, especially by enterovirus 71 (EV71) and coxsackievirus A16 (CA16). Patients infected with different enteroviruses show varied clinical symptoms. The aim of this study was to determine whether the etiological spectrum of mild and severe HFMD changed, and the association between pathogens and clinical features. From 2009 to 2013, a total of 2,299 stool or rectal specimens were collected with corresponding patient data. A dynamic view of the etiological spectrum of mild and severe HFMD in Shenzhen city of China was provided. EV71 accounted for the majority proportion of severe HFMD cases and fatalities during 2009-2013. CA16 and EV71 were gradually replaced by coxsackievirus A6 (CA6) as the most common serotype for mild HFMD since 2010. Myoclonic jerk and vomiting were the most frequent severe symptoms. Nervous system complications, including aseptic encephalitis and aseptic meningitis were observed mainly in patients infected by EV71. Among EV71, CA16, CA6, and CA10 infection, fever and pharyngalgia were more likely to develop, vesicles on the hand, foot, elbow, knee and buttock were less likely to develop in patients infected with CA10. Vesicles on the mouth more frequently occurred in the patients with CA6, but less in the patient with EV71. Associations between diverse enterovirus serotypes and various clinical features were discovered in the present study, which may offer further insight into early detection, diagnosis and treatment of HFMD. © 2015 Wiley Periodicals, Inc.

A case is reported of a 36-year-old male, found dead in his locked room, lying on a bed, dressed in his mother's clothes, with a plastic bag over his head, hands tied and with a barrel wooden cork in his rectum. Two pornographic magazines were found on a chair near the bed, so that the deceased could see them well. Asphyxia was controlled with a complex apparatus which consisted of two elastic luggage rack straps, the first surrounding his waist, perineum, and buttocks, and the second the back of his body, and neck. According to the psychological autopsy based on a structured interview (SCID-I, SCID-II) with his father, the deceased was single, unemployed and with a part college education. He had grown up in a poor family with a reserved father and dominant mother, and was indicative of fulfilling DSM-IV diagnostic criteria for alcohol dependence, paraphilia involving hypoxyphilia with transvestic fetishism and anal masturbation and a borderline personality disorder. There was no evidence of previous psychiatric treatment. The Circumstances subscale of Beck's Suicidal Intent Scale (SIS-CS) pointed at the lack of final acts (thoughts or plans) in anticipation of death, and absence of a suicide note or overt communication of suicidal intent before death. Integration of the crime scene data with those of the forensic medicine and psychological autopsy enabled identification of the event as an accidental death, caused by neck strangulation, suffocation by a plastic bag, and vagal stimulation due to a foreign body in the rectum.

Liposuction and lipofilling for treatment of symptomatic silicone toxicosis of the gluteal region.

Silicone injection can cause numerous posttreatment complications-including debilitating pain, cellulitis, abscesses, overlying skin compromise, and siliconomas distorting overlying tissues-that can be difficult to manage. The authors evaluate liposuction as a treatment for patients experiencing complications from silicone injections to the gluteal region, to both preserve aesthetic appearance and minimize further risk of complication from these procedures. Eight patients (7 women and 1 man) who presented consecutively to us between 2010 and 2013 with complications from silicone injections to their gluteal region were enrolled in this study. Each patient was evaluated by computed tomography scan and a 0 to 6 visual analog scale for pain. Emergency room (ER) visits, previous hospital admissions, and cellulitis requiring antibiotics in the 12 months prior to treatment were recorded. Patients were treated with ultrasonic and standard liposuction followed by lipotransfer into the gluteal musculature. A Student t test was used for statistical comparison of pre- and postoperative values. Average patient age was 36 years (range, 25-43 years). All patients initially presented with intense pain as assessed by a visual analog scale; by the 12th week postoperatively, the entire cohort experienced remission in pain. At 1 year postoperatively, no patients had infections (vs 75% preoperatively; P = .028), visited the ER (vs 50% preoperatively; P = .058), or were hospitalized (vs an average of 1.5 hospitalizations per patient preoperatively; P = .066). Liposuction with immediate intramuscular fat transfer for buttock augmentation appears to be a safe surgical option that preserves aesthetic appearance for patients with gluteal silicone toxicosis.

To evaluate skin irritation and patch adhesiveness of a new weekly low-dose levonorgestrel (LNG) and ethinyl estradiol (EE) contraceptive patch (LNG/EE patch). This analysis was part of an open-label, parallel-group, multicenter, phase 3 study that randomized healthy women to the LNG/EE patch (one patch weekly for three consecutive weeks, followed by a patch-free week for 13 cycles) or to an oral contraceptive for six cycles followed by seven LNG/EE patch cycles. Participants selected patch application sites of abdomen, buttock or upper torso. Investigators rated patch adhesiveness and skin irritation using standardized scales. Participants rated skin irritation and itching daily using standardized scales and recorded patch fall-off on daily diary cards. A total of 32,508 patches were applied (n=1273). At the five clinic visits in which investigators rated the patches, they rated adhesiveness=0 (no lift) for ≥84% of participants and skin irritation=absent/mild for 97% of patches. Participants reported that 2-3.7% of patches fell off and rated skin irritation as absent or mild for 92- 95% of patches, according to site. Investigator- and participant-rated assessments of LNG/EE patch adhesiveness and irritation demonstrated a low incidence of patch detachment, skin irritation and pruritus. This secondary analysis of a phase 3 clinical trial of a new weekly low-dose LNG and EE contraceptive patch, which used assessment by both investigators and participants, observed a low incidence of skin irritation, pruritus and patch detachment.

Medial telangiectatic vascular nevi are capillary vascular malformations frequently observed at birth occurring mostly on the face or on the nape as a single lesion or as multiple macules affecting more than one site simultaneously. In 1990, Metzker and Shamir reported a medial telangiectatic vascular nevus (MTVN) in the sacral region along the midline and called this particular variety of MTVN 'butterfly-shaped mark'. Our study was performed to investigate the morphology and localization of an MTVN in the sacral region (sMTVN) in a group of Caucasian children. We observed 43 children with sMTVN, ranging in age from 1 month to 12 years (mean 8 years), for a period of 6 years. sMTVN was found as a red-violet macular lesion of rhomboid or triangular shape in 16 patients and as a group of little red-violet macules in 10 patients. In 16 patients moreover the whole back was involved with many small red-violet spots on and around the spinal column, and in 1 patient with classic sMTVN satellite macules were also present over both buttocks. Four patients suffered from epilepsy with mental deficiency. In 6 patients, the family history showed sMTVN in one or more members of the family. No case presented an association with spina bifida. In our study, sMTVN shows a morphological polymorphism while Metzker and Shamir reported the same clinical aspect in all 25 of their patients. In accordance with these authors, we noted that sMTVN persist into childhood and adult life in the same way as occipital MTVN.

Ultrasound (US) aids clinical management of skin and soft tissue infection (SSTI) by differentiating non-purulent cellulitis from abscess. However, purulent SSTI may be present without abscess. Guidelines recommend incision and drainage (I & D) for purulent SSTI, but US descriptions of purulent SSTI without abscess are lacking. We retrospectively reviewed pediatric emergency department patients with US of the buttock read as negative for abscess. We identified US features of SSTI with adequate interobserver agreement (kappa > 0.45). Six independent observers then ranked presence or absence of these features on US exams. We studied association between US features and positive wound culture using logistic regression models (significance at p < 0.05). Of 217 children, 35 patients (16%) had cultures positive for pathogens by 8 h after US and 61 patients (32%) had cultures positive by 48 h after US. We found kappa > 0.45 for focal collection > 1.0 cm (κ = 0.57), hyperemia (κ = 0.57), swirling with compression (κ = 0.52), posterior acoustic enhancement (κ = 0.47), and cobblestoning or branching interstitial fluid (κ = 0.45). Only cobblestoning or interstitial fluid was associated with positive wound cultures in logistic regression models at 8 and 48 h. Cobblestoning or interstitial fluid on US may indicate presence of culture-positive, purulent SSTI in patients without US appearance of abscess. Although our study has limitations due to its retrospective design, this US appearance should alert imagers that the patient may benefit from early I & D.

Probable fenofibrate-induced acute generalized exanthematous pustulosis.

The case of a patient who experienced a severe adverse reaction requiring emergency treatment after a single dose of fenofibrate is described. A 58-year-old woman with type 1 diabetes was hospitalized for treatment of an extensive blistering rash on the buttocks and trunk accompanied by fever, hypotension, tachycardia, neutrophilia, impaired renal function, and liver enzyme abnormalities. She reported that two days previously she had developed fever and vomiting four hours after taking her first dose of fenofibrate (145 mg). The patient required vasopressor support and was initially treated with broad-spectrum antibiotics for 3 days and a course of immune globulin. On hospital day 4, histopathology returned results consistent with acute generalized exanthematous pustulosis (AGEP), and the patient was subsequently treated with topical steroids. Gradual resolution of AGEP was noted at the time of her discharge from the hospital on day 7 and at one-week follow-up. Analysis of the case using the adverse drug reaction probability scale of Naranjo et al. yielded a score of 5, indicating a probable association between fenofibrate use and AGEP development. AGEP is a predominantly drug-induced condition but is not typically associated with fenofibrate use. Cutaneous eruptions in AGEP are often accompanied by systemic symptoms (e.g., fever, leukocytosis), and the disorder can also be associated with impaired creatinine clearance and elevated aminotransaminase levels. A woman with type 1 diabetes developed AGEP after taking a single dose of fenofibrate. Her cutaneous symptoms began to resolve within days of discontinuation of fenofibrate use.

Severe infection, inadequate food intake, and pressure ulcers in patients with type 2 diabetes can result in malnutrition. We describe a case in which rehabilitation nutrition was effective for treat-ing a pressure ulcer in a malnourished patient with type 2 diabetes. A 58-year-old man with type 2 diabetes was diagnosed with hidradenitis suppurativa on the left buttock and thigh and a severe pres-sure ulcer on his left kneecap. Malnutrition was related to hypermetabolism caused by chronic hidradenitis suppu-rativa and inadequate protein-energy intake before admission. We initiated a rehabilitation nutrition intervention to improve physical function and to treat a pressure ulcer by prescribing 2,000 kcal/day of food, including 80 g of protein, and physical rehabilitation for 40 minutes/day. The patient showed good progress in terms of his physical function and healing of the pressure ulcer. After prescribing 2,250 kcal/day of food, including 85 g of protein, and physical rehabilitation for 60 minutes/day, HbA1c levels increased to 7.4%. The energy prescription was de-creased to 2,000 kcal/day to improve glycemic levels. Then, the patient's weight decreased and his hand grip strength became weaker. On day 134 and discharge the patient could walk independently with a t-cane and ankle supporter. By day 14 after discharge, the pressure ulcer had epithelialized. Rehabilitation nutrition management improved physical function and facilitated pressure ulcer healing in a malnourished patient with type 2 diabetes. Close conjoint management of hyperglycemia was also necessary.

The concept of comfort is one way for the growing airline market to differentiate and build customer loyalty. This work follows the idea that increasing the contact area between human and seat can have a positive effect on comfort [5, 6, 7]. To improve comfort, reduce weight and optimise space used, a human contour shaped seat shell and cushioning was developed. First the most common activities, the corresponding postures and seat inclination angles were defined. The imprints of these postures on a rescue mat were 3D scanned and an average human contour curve was defined. The outcome was transferred to a prototype seat that was used to test the effect on perceived comfort/discomfort and pressure distribution. The resulting human contour based prototype seat has comfort and discomfort scores comparable to a traditional seat. The prototype seat had a significantly lower average pressure between subjects' buttocks and the seat pan over a traditional seat. This study shows that it is possible to design a seat pan and backrest based on the different contours of study subjects using 3D scan technology. However, translating the 3D scans into a prototype seat also showed that this can only be seen as a first step; additionally biomechanical information and calculations are needed to create ergonomic seats. Furthermore, it is not possible to capture all different human shapes and postures and translate these into one human contour shape that fits all activities and all human sizes.

One of the most common problems in pottery manufacturing process is musculoskeletal disorders on workers. This disorder was caused by uncomfortable posture where the workers sit on the floor with one leg was folded and another was twisted for long duration. Back, waist, buttock, and right knee frequently experience the disorders. The objective of this research is to investigate the muscle contraction at such body part of workers in manufacturing process of pottery. Electromyography is used to investigate the muscle contraction based on the median frequency signal. Focus measurements is conducted on four muscles types. They are lower interscapular muscle on the right and left side, dorsal lumbar muscle, and lateral hamstring muscle. Statistical analysis is conducted to test differences of muscle contraction between female and male. The result of this research showed that the muscle which reached the highest contraction is dorsal lumbar muscle with the average of median frequency is 51,84 Hz. Then followed by lower interscapular muscle on the left side with the average of median frequency is 31,30 hz, lower interscapular muscle on the right side average of median frequency is 31,24 Hz, and lateral hamstring muscle average of median frequency is 21,77 Hz. Based on the statistic analysis result, there were no differences between male and female on left and right lower interscapular muscle and dorsal lumbar muscle but there were differences on lateral hamstring muscle with the significance level is 5%. Besides that, there were differences for all combination muscle types with the level of significance is 5%.

Currently, innovative methods to prevent photoaging are needed. Skin-derived precursors (SKP) have been shown to play a crucial role in resisting UVB-induced apoptosis in vitro. The objective of this study was to explore the effect of SKP on preventing skin photoaging in vivo. Skin-derived precursors from neonatal BALB/c mice were isolated, identified and intradermally transplanted with a PKH26 label to track their survival. These were then injected at different concentrations into the buttock dermis of nude mice at 2-weekly intervals before UV irradiation. Photographs, assessment of live skin surface, histology with quantitative real-time polymerase chain reaction and immunohistochemistry were used to evaluate the impact of SKP on wrinkles and other relevant indicators of skin photoaging. SKP exhibited a sphere-like structure and could survive for at least 2 weeks after intradermal transplantation. A large dose of SKP transplantation (10 5 SKP +UV) at 2-weekly intervals were able to ameliorate coarse UV-induced wrinkles. Moreover, the skin smoothness value, dermal thickness and collagen percentage were significantly increased in mice that received a large dose of SKP (10 5 SKP +UV). UV radiation induced the mRNA expression of MMP-13 and decreased the mRNA and protein expression of TβRII, but these effects were diminished by SKP transplantation. The transplantation of SKP could increase the mRNA of TIMP-1. We found that transplanted SKP exert a beneficial impact on preventing UV-induced wrinkles in vivo, suggesting that SKP transplantation is a promising candidate for preventing photoaging. © 2018 The Australasian College of Dermatologists.

[Purpose] Musculoskeletal disorders are common causes of work-related disability in different professions involving the frequent practice of lifting, stooping, twisting, prolonged sitting, or standing. The dental profession is one such profession. Our aim was to determine the prevalence of work-related musculoskeletal disorders among dental professionals in Saudi Arabia, the factors associated with them, and their consequences and to propose preventive measures for them. [Subjects and Methods] A self-administered online questionnaire was sent to 225 members of the Saudi Dental Association. It included questions on demographic and professional characteristics, general medical history, and history of work-related musculoskeletal disorders before and after joining the dental profession. [Results] The questionnaire was completed by 65% of the respondents. Among them 85% reported that they had developed some pain due to work after joining the dental profession, and 42% reported that they were suffering pain at the time of the survey. Besides lower back, shoulder, and neck regions, the hands, upper back, and other regions like the elbows, buttocks, thighs, leg, and feet were areas in which they pain. [Conclusion] The prevalence of work-related musculoskeletal disorders among dental professionals in Saudi Arabia is high, affecting their daily activities, sometimes even forcing them to change their work setting. Age, gender, specialty of work, work setting, number of contact hours with patients, etc., were all found to be related to their work-related pain. We need to emphasize the role of ergonomics, counseling, proper techniques of patient handling, etc., during the training of dental professionals so that they can work efficiently. PMID:25995567

Zoledronic acid-associated symmetrical drug-related intertriginous and flexural exanthema (SDRIFE): report of baboon syndrome in a woman with recurrent metastatic breast cancer after receiving zoledronic acid.

Baboon syndrome is a distinctive skin reaction in which the patient typically develops erythematous buttocks that appear similar to those of a baboon. The non-contact allergenic variant of baboon syndrome is also referred to as symmetrical drug-related intertriginous and flexural exanthema (SDRIFE). Zoledronic acid is a bisphosphonate that is used in patients with metastatic cancer to prevent bone complications. Zoledronic acid-associated baboon syndrome is described in a woman with recurrent metastatic breast cancer. PubMed was used to search the following terms, separately and in combination: baboon syndrome, breast cancer, symmetrical drug-related intertriginous and flexural exanthema, and zoledronic acid. All papers were reviewed and relevant manuscripts, along with their reference citations, were evaluated. Zoledronic acid has infrequently been associated with mucocutaneous adverse reactions. However, baboon syndrome has not previously been observed in patients receiving zoledronic acid. The reported woman developed baboon syndrome after her initial exposure to zoledronic acid. Non-contact allergenic drug-induced baboon syndrome has most commonly been associated with antibiotics such as beta-lactams and penicillins. Zoledronic acid-associated baboon syndrome has not previously been observed in cancer patients. Baboon syndrome (SDRIFE variant) was observed in a woman with recurrent metastatic breast cancer after her first exposure to zoledronic acid. In summary, SDRIFE can occur in oncology patients receiving zoledronic acid and zoledronic acid should be added to the list of medications associated with the potential to cause non-contact allergenic drug-induced baboon syndrome.

To identify difficulties for nurses in differentiating between moisture lesions and pressure ulcers, proper classification of pressure ulcers to assess the adequate classification of the Grupo Nacional para el Estudio y Asesoramiento de Úlceras por Presión y Heridas Crónicas (GNEAUPP) and the degree of agreement in the correct assessment by type and category of injury. Cross-sectional study in a critical area during 2014. All nurses who agreed to participate were included. They performed a questionnaire with 14 photographs validated by experts of moisture lesions or pressure ulcers in the sacral area and buttocks, with 6 possible answers: Pressure ulcer category I, II, III, IV, moisture lesions and unknown. Demographics and knowledge of the classification system of the pressure ulcers were collected according to GNEAUPP. It involved 98% of the population (n=56); 98.2% knew the classification system of the GNEAUPP; 35.2% of moisture lesions were considered as pressure ulcers, most of them as a category II (18.9%). The 14.8% of the pressure ulcers photographs were identified as moisture lesions and 16.1% were classified in another category. The agreement between nurses earned a global Kappa index of .38 (95% CI: .29-.57). There are difficulties differentiating between pressure ulcers and moisture lesions, especially within initial categories. Nurses have the perception they know the pressure ulcers classification, but they do not classify them correctly. The degree of concordance in the diagnosis of skin lesions was low.

Early excision and grafting, an alternative approach to the surgical management of large body surface area levamisole-adulterated cocaine induced skin necrosis.

Miner, Jason; Gruber, Paul; Perry, Travis L

2015-05-01

Levamisole-adulterated cocaine as a cause of retiform purpura progressing to full-thickness skin necrosis was first documented in 2003 and currently comprises over 200 reported cases. Whereas, its presentation, pathophysiology, and diagnostic workup have been reasonably well-defined, only one publication has significantly detailed its surgical management. For this reason there exists a relative absence of data in comparison to its reported incidence to suggest a preferred treatment strategy. In the case mentioned, treatment emphasized delayed surgical intervention while awaiting lesion demarcation and the monitoring of autoantibodies. At our institution we offer an alternative approach and present the case of a 34 year old female who presented with 49% TBSA, levamisole-induced skin necrosis managed with early surgical excision and skin grafting. The patient presented three days following cocaine exposure with painful, purpura involving the ears, nose, buttocks, and bilateral lower extremities which quickly progressed to areas of full-thickness necrosis. Lab analysis demonstrated elevated p-ANCA and c-ANCA, as well as leukopenia, decreased C4 complement, and urinalysis positive for levamisole, corroborating the diagnosis. Contrasting the most thoroughly documented case in which the patient underwent first surgical excision on hospital day 36 and underwent 18 total excisions, our patient underwent first excision on hospital day 10 and received only one primary excision prior to definitive autografting. To our knowledge, this is the largest surface area surgically treated that did not result in surgical amputation or autoamputation of limbs or appendages, respectively. We contend that early excision and grafting provides optimal surgical management of this syndrome while avoiding the morbidity seen with delayed intervention. Published by Elsevier Ltd.

The aims of this study were to describe clinical and laboratory manifestations of patients with levamisole-adulterated cocaine-induced vasculitis/vasculopathy and to propose a skin classification according to the distribution and severity of lesions. We report the characteristics of 30 patients admitted with levamisole-adulterated cocaine-induced vasculitis/vasculopathy in 4 high-complexity institutions in Colombia, from December 2010 to May 2017. We compare our findings with the principal published series. Median age was 31 years (interquartile range, 27-38 years) with a male-to-female ratio of 5:1. Eighty-three percent of the patients had retiform purpura affecting the limbs, buttocks, face, or abdomen; 73% had ear necrosis, 50% cutaneous ulcers, 17% genital necrosis, 13% oral ulcers, and 10% digital necrosis. Cutaneous involvement was classified according to the frequency of the compromised corporal area, and purpuric lesions were stratified in 4 grades of severity. Anti-neutrophil cytoplasmic autoantibodies were positive in 85% of the cases, lupus anticoagulant in 73%, and antinuclear autoantibodies in 57%, and rheumatoid factor was negative in all cases. We found nephritis in 17 cases (57%). Prednisolone was used in most of the patients (70%), with other immunosuppressive agents being used in a lower percentage. Improvement was observed in 93% of the patients, but symptoms recurred in 40%, attributed to relapses in consumption. End-stage chronic renal disease developed in 10% of the cases, and 1 patient died. Because of rising cocaine consumption and levamisole adulteration frequency, levamisole-adulterated cocaine-induced vasculitis/vasculopathy is becoming more common. Detailed characterization of skin involvement coupled with multiple antibody positivity is essential for a diagnosis. Renal involvement is frequent, clinically and histologically heterogeneous, and potentially serious.

The purpose of this study was to describe the occurrence of ischiofemoral impingement (IFI) and hamstring dysfunction following malunion or non-union of ischial tuberosity apophyseal avulsion fractures and report the short-term outcomes of surgical treatment with regard to alleviating symptomatic extra-articular impingement. All patients who underwent surgery for recalcitrant hip and buttock pain in the setting of prior ischial tuberosity avulsion fracture at three tertiary-level hip preservation centres were included for this review. A total of ten patients met our inclusion criteria and underwent sciatic neurolysis, resection of the ischial tuberosity fragment and hamstring reattachment. Clinical outcomes scores were collected post-operatively including the Modified Harris Hip Score (mHHS) and the Hip Outcomes Score (HOS). Ten patients with a mean age of 18 years (range 14-28) underwent surgery for symptomatic ischiofemoral impingement after ischial tuberosity avulsion fracture. At a mean of 2.2-year follow-up (range 1.7-3.5), the median post-operative mHHS was 89.7 (65.7-96.8) and HOS ADL and Sport subscales were 90 % or greater in all cases. Five patients (50 %) rated their hip as normal, and five patients (50 %) rated their hip as near normal. Malunion or non-union following ischial tuberosity apophyseal fracture can lead to IFI and hamstring dysfunction. Clinically, the resultant pain and dysfunction is often chronic, and can be debilitating. In select cases, a reliable surgical technique is presented to improve hamstring function and correct ischiofemoral impingement in this setting with good-to-excellent outcomes in the majority of cases at short-term follow-up.

There have not been any published studies on the use of radiofrequency (RF)-light-based technologies for the treatment of cellulite. Only preliminary results have recently been reported (ASDS Proceedings, September 2004). This two-center study investigated the safety and effectiveness of combined energies for cellulite treatment using the VelaSmoothtrade mark system. Thirty-five female subjects with cellulite and/or skin irregularities on the thighs and/or buttocks were treated with the VelaSmooth device. Patients received from eight to 16 treatments twice weekly. All patients maintained their normal lifestyle, and diet and fluid consumption. The circumference of the right and left medial thighs was measured at both baseline and approximately 4 weeks after the last treatment. During the last follow-up visit, the physician graded the level of improvement in skin smoothing and/or cellulite improvement using pre- and post-treatment photographs. Three patients provided biopsy specimens for histological assessment. All study patients showed some level of reduction in thigh circumference after 8 weeks of treatment; indeed, 70% of all patients showed such a reduction after 4 weeks of treatment. Also, 100% of all patients showed some level of improvement in skin texture and cellulite. The mean decrease in circumference was 0.8 inches. Some patients demonstrated reductions of more than 2 inches. There were minimal complications associated with treatment. This preliminary study demonstrates that the VelaSmooth system can have a beneficial effect on cellulite appearance. Further studies are needed to better define the mechanisms by which RF and light energies affect subdermal tissues and develop a method of quantified cellulite analysis.

Prevention of Fat Embolism in Fat Injection for Gluteal Augmentation, Anatomic Study in Fresh Cadavers.

Liposuction is a popular surgical procedure. As in any surgery, there are risks and complications, especially when combined with fat injection. Case reports of fat embolism have described a possible explanation as the puncture and tear of gluteal vessels during the procedure, especially when a deep injection is planned. A total of 10 dissections were performed in five fresh cadavers. Each buttocks was divided into four quadrants. We focused on the location where the gluteal vessels enter the muscle and the diameter of the vessels. Colorant at two different angles was injected (30° and 45°). We evaluated the relation of the colorant with the main vessels. We found two perforators per quadrant. The thickness of the gluteal muscle was 2.84 ± 1.54 cm. The area under the muscle where the superior gluteal vessels traverse the muscle was located 6.4 ± 1.54 cm from the intergluteal crease and 5.8 ± 1.13 cm from the superior border of the muscle. The inferior gluteal vessels were located 8.3 ± 1.39 cm from the intergluteal crease and 10 ± 2.24 cm from the superior border of the muscle. When we compared the fat injected at a 30° angle, the colorant stayed in the muscle. Using a 45° angle, the colorant was in contact with the superior gluteal artery and the sciatic nerve. No puncture or tear was observed in the vessels or the nerve. The location where the vessels come in contact with the muscle, which can be considered for fat injection, were located in quadrants 1 and 3. A 30° angle allows for an injection into the muscle without passing into deeper structures, unlike a 45° injection angle.

Striae distensae are dermal scars with flattening and atrophy of the epidermis. Successful treatment of these stretch marks has been disappointing. The non-ablative 1,450-nm diode laser has been shown to improve atrophic scars and may be expected to improve striae. As yet, no study has been published to document the effects of this laser on striae. Our aim is to evaluate the efficacy of the 1,450-nm diode laser in the treatment of striae rubra and striae alba in Asian patients with skin types 4-6. Striae on one half of the body in 11 patients were treated with the 1,450-nm diode laser with cryogen cooling spray with the other half serving as a control. The following parameters were used: 6 mm spot size and dynamic cooling device (DCD) for 40 milliseconds to protect the epidermis. Patients were randomly assigned to receive either 4, 8, or 12 J/cm2. A total of three treatments were given at 6-week intervals. The following sites were treated: abdomen, arms, back, buttocks, and thighs. Two patients had striae rubra and nine striae alba. Clinical photographs were taken before and after each treatment and analysis was undertaken through photographic evaluation by non-treating physicians. At 2 months after the last treatment, no patients showed any noticeable improvement in the striae on the treated side compared to baseline and to the control areas. Side effects were limited to transient erythema and postinflammatory hyperpigmentation (PIH), which occurred in seven (64%) patients. The non-ablative 1,450-nm diode laser is not useful in the treatment of striae in patients with skin types 4, 5, and 6. 2006 Wiley-Liss, Inc.

Chronic pain is the frequent and significantly challenging complications in persons with spinal cord injury (SCI). Socio-cultural background may lead people perceive and manage pain differently. The study aims to describe the chronic pain experience and pain management of SCI persons in Nepal. A descriptive cross sectional study was conducted among purposively selected sample of 120 SCI persons with chronic pain living in the eight districts of Bagmati Zone of Nepal. The data were collected using the International Spinal Cord Injury Pain Basic Data Set Version 2 (ISCIPBDS-2) and Open-ended Pain Management Questionnaire. The data were analyzed using descriptive statistics and content analysis method. The back (n=84), lower legs/feet (n=63) and buttocks/hips (n=51) was found as the common pain locations. In common, the onset of pain was found within the first 6 month of the injury. Overall pain intensity and pain interference were found to be at the moderate level. The SCI persons used pain medications and non-pharmacological pain management. Ibuprofen was the commonly used pain medication and commonly used non-pharmacological pain management methods included physical support (e.g. massage, exercise), relaxation (e.g. distraction, substance abuse), coping (e.g. acceptance, praying), and traditional herbs. SCI persons had chronic pain experience which interfered with their daily living. They used pain medications and non-pharmacological pain management methods based on their beliefs, knowledge, and community resources in Nepal. This study provides some evidence to help the team of rehabilitation professional to plan and help SCI persons with chronic pain. Based on these findings, chronic pain management intervention for SCI persons should be developed and supported continuously from hospital to home based community context of Nepal.

Despite several consensus statements, different injury definitions are used in the literature. This study aimed to identify the impact of different injury definitions on the nature and incidence of complaints captured during a short-term running program for novice runners. Prospective cohort study. 1696 participants completed weekly diaries on running exposure and musculoskeletal complaints during a 6-week running program. These data were used to compare six different injury definitions (presence of running-related pain, training-reduction, time-loss of one day or one week). Injuries were registered under these different definitions. Consequently incidence and the nature of complaints were compared between definitions. The different injury definitions resulted in incidences that varied between 7.5% and 58.0%, or 18.7 and 239.6 injuries per 1000h of running. The median duration of injury complaints was 4-7 days for injuries registered under a 'day definition', while complaints registered under a 'week definition' lasted 20-22 days. For running-related pain injuries the median of the maximum amount of pain was 3.0. In training-reduction and time-loss injuries these median values were scored between 5.0 and 7.0. No significant differences in anatomical locations between injuries that were registered under a 'day definition' or a 'week definition' were found. Injuries registered under a time-loss definition were located relatively more often at the knee, while complaints at the pelvis/sacrum/buttock were captured more often under a running-related pain definition. Injury definitions largely impact injury incidence. Location of injury is also affected by choice of injury definition. This stressed the need for standardized injury registration methods.

To clarify the histopathology of acute osteomyelitis, chronic osteomyelitis, primary vasculitis, and secondary-type vasculitis. This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. After participating in this educational activity, the participant should be better able to:1. Describe the parameters and significance of this study.2. Identify chronic wound diagnosis and treatment.3. Differentiate the histopathology of osteomyelitis and vasculitis. The presence of a chronic wound can result in significant morbidity/mortality. Understanding the pathological alterations of wound tissue that are refractory to standard wound therapy is essential for effective wound management and healing. The authors describe 4 wound etiologies, specifically, acute osteomyelitis, chronic osteomyelitis, primary vasculitis, and secondary-type vasculitis. A tertiary care hospital. A retrospective review of 1392 wound operations performed during a 24-month period at a tertiary care hospital was conducted. Tissue specimens reviewed included soft tissue infections of the lower extremity, sacrum, hip/pelvis, trunk, perineum, and buttocks. Acute osteomyelitis is defined as bone tissue with a predominance of polymorphonuclear leukocytes, evidence of osteoclast bone resorption with scalloping of the cortical bone edges, and bone detritus. Chronic osteomyelitis is defined as bone tissue with a significant amount of fibrosis surrounding devitalized tissue and heavy infiltration of lymphocytes and plasma cells. Primary-type vasculitis is defined primarily as inflammation and necrosis of blood vessel walls. In cutaneous lesions of granulomatosis with polyangiitis, ulceration with numerous inflammatory granulomas is seen in the papillary dermis. Secondary vasculitis is defined by vessel wall infiltration by inflammatory cells and fibrinoid necrosis of the small vessel wall. Pathologies of these 4 types of wounds can complicate standard algorithms designed for diagnosis and treatment, and accurate diagnosis through histopathologic analysis can help tailor targeted treatment.

In the early 1990's staff at a Royal Naval Air Station formed the view that pilots and observers of the Navy Lynx helicopter fleet appeared to have a higher incidence of back pain, to be seeking medical assistance more frequently and to be spending more time medically "unfit to fly" when compared to their counterparts in other helicopters. To quantify the incidence of low back pain in helicopter aircrew by use of a questionnaire. A questionnaire was used to establish the prevalence and nature of back pain in Naval aircrew (161) compared to a control group of randomly selected non-flying military personnel (310). Results show that aircrew (82%) experience significantly more back pain than controls (52%) (p < 0.01) though the nature of pain was similar in both groups. Significantly more aircrew (73%) than controls (49%) (p < 0.01) reported a previous history of back pain and report pain in shoulders (19%), midback (42%), lower back (72%) and across the buttocks (12%). Ergonomic factors were thought to be causative. Of aircrew surveyed, 11 (8%) had been issued with personal lumbar supports which resulted in major subjective improvements in flight-related symptoms. Helicopter aircrew have a higher incidence of back pain. Crew station design was identified as a major contributor to the prevalence of back pain while personal supports reduced the levels of discomfort. While these findings are not new, no significant steps have been taken to redesign the crew station. It is recommended that personal supports are provided to all aircrew and that a more detailed study of crew station ergonomics is indicated following a more comprehensive study of prevalence of back pain in Royal Navy aircrew.

Proper diagnosis and treatment of sacroiliac joint (SIJ) pain remains a clinical challenge. Dysfunction of the SIJ can produce pain in the lower back, buttocks, and extremities. Triangular titanium implants for minimally invasive surgical arthrodesis have been available for several years, with reputed high levels of success and patient satisfaction. This study reports on a novel hydroxyapatite-coated screw for surgical treatment of SIJ pain. Data were prospectively collected on 32 consecutive patients who underwent minimally invasive SIJ fusion with a novel hydroxyapatite-coated screw. Clinical assessments and radiographs were collected and evaluated at 3, 6, and 12 months postoperatively. Mean (standard deviation) patient age was 55.2 ± 10.7 years, and 62.5% were female. More patients (53.1%) underwent left versus right SIJ treatment, mean operative time was 42.6 ± 20.4 minutes, and estimated blood loss did not exceed 50 mL. Overnight hospital stay was required for 84% of patients, and the remaining patients needed a 2-day stay (16%). Mean preoperative visual analog scale back and leg pain scores decreased significantly by 12 months postoperatively (P < 0.01). Mechanical stability was achieved in 93.3% (28/30) of patients, and all patients who were employed preoperatively returned to work within 3 months. Two patients who required revision surgery reported symptom improvement within 3 weeks and did not require subsequent surgery. Positive clinical outcomes are reported 1 year postoperatively after implantation of a novel implant to treat sacroiliac joint pain. Future clinical studies with larger samples are warranted to assess long-term patient outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

a Decade of Improvement in Whole-Body Vibration and Low Back Pain for Freight Container Tractor Drivers

Nishiyama, K.; Taoda, K.; Kitahara, T.

1998-08-01

The authors' study in 1983 revealed that the whole-body vibration of the tractor units of freight containers was most hazardous in the back-to-chest directions (x-axis). The allowable exposure time was considerably shorter than that for heavy duty trucks. The low back pain (LBP) among the drivers seemed to be due to the long working hours and the ergonomically unsound tractor design, as well as the vibration. A preventative measure was the introduction of a tractor cab suspended by an air spring instead of a steel spring. In 1992, a follow-up field study was conducted. A personal vibration exposure meter developed by us measured the whole-body vibration on eight tractors. Eighty-nine triplets matched with the age and the years of driving tractors answered a questionnaire evaluation of the ergonomics of their tractor units.The comparison of the newest steel suspension vehicles to the old ones produced by the same motor company revealed that in thex-axis the vibration level had decreased by as much as 4 to 9 dB. Some tractors showed an increase in vibration in the buttocks-to-head direction (z-axis). However, such adverse changes seemed not to affect evaluations according to the fatigue-decreased proficiency boundary (FDP) and the exposure limit (EL) recommended in ISO 2631-1978. The present models, regardless of the type of suspension, changed the direction of the most hazardous vibration from thex-axis to thez-axis. However, the effect of the air-suspension was not so remarkable as expected. Among 40% of drivers seemed to exceed the FDP boundary during a day.The questionnaire study showed an improvement in the ergonomic evaluation of the tractors. The air suspension models seemed to induce less LBP than the steel suspension models.

Only a few studies characterized cutaneous non-tuberculous Mycobacterium (NTM) infections in this region of the world. Objective  The aim of this study was to describe the epidemiological, clinical and histological findings of cutaneous NTM infections in Lebanon. Retrospective study of 17 patients (19 histological specimens) diagnosed with cutaneous NTM infections and confirmed by culture-based partial sequencing of the 16S rRNA gene at the American University of Beirut Medical Center between 2005 and 2008. Of 17 cases, 14 were caused by Mycobacterium marinum. All patients were immunocompetent except for one. Clinically, the most common presentation was multiple sporotrichoid lesions over an extremity (8/17). Many patients had peculiar presentations including bruise-like patches, herpetiform lesions, annular ulcerated plaques, symmetrical nodules over the buttocks and locally disseminated lesions with surrounding pale halo. Almost all patients cleared their infection on either minocycline or clarithromycin monotherapies. Histologically, a dermal small vessel proliferation with mixed inflammation (granulation tissue-like changes) was identified in 58% of specimens. The most common type of granulomatous inflammation was the suppurative (47%) followed by the tuberculoid (30%), sarcoidal (11%), and palisading (5%) types. Lichenoid granulomatous dermatitis was noted in 42% of cases. Special staining highlighted mycobacteria in only two specimens. The incidence of cutaneous NTM infections is high in our area. Many patients had peculiar clinical presentations. Our study is the second to report the common presence of granulation tissue-like changes as a good histological indicator of cutaneous NTM infections. Minocycline and clarithromycin remain the drugs of choice in our area. © 2010 The Authors.

Necrotizing fasciitis (NF) is a rare, potentially fatal, infective complication that can occur after surgery. Diagnosis is still difficult and mainly based on clinical data. Only a prompt pharmacological and surgical therapy can avoid dramatic consequences. There are few reports regarding NF as a complication after aesthetic surgical procedures, and a systematic review still lacks. We have performed a systematic review of English literature on PubMed, covering a period of 30 years. Keywords used were "necrotising fasciitis" matched with "aesthetic surgery complications", "breast surgery", "mammoplasty", "blepharoplasty", "liposuction", "facelift", "rhinoplasty fasciitis", "arm lift", "thigh lift", "otoplasty" and "abdominoplasty fasciitis". No additional search and temporal limitation were set. Among 3782 papers concerning NF, only 18 were related to NF after an aesthetic surgical procedure. Liposuction was the most affected procedure, with buttocks and lower extremity the most involved anatomical regions. The majority of the infections were monomicrobial, promoted by Streptococcus pyogenes. In most cases, NF occurred within the third post-operative day with non-specific signs and symptoms. In 14 cases, a single or multiple surgical interventions were performed and survival was achieved in 11 patients. In case of infection after aesthetic surgery, we should always bear in mind NF. Clinical hallmarks still guide NF management. Because early signs and symptoms are usually non-specific, a strict clinical control is highly suggested. Once clinical suspicion is raised, prompt antibacterial therapy should be administered, followed by surgical debridement in case of ineffective response.

To study the success rate, predictors for success, and pregnancy outcomes after external cephalic version. Historical cohort study. Regional hospital, Hong Kong. All women who had singleton term breech pregnancies at term and opted for external cephalic version during 2001 and 2009. Their demographic data, clinical and ultrasound findings, procedure details, complications, and delivery outcomes were analysed. Predictive factors for successful external cephalic version. A total of 209 external cephalic versions were performed during the 9-year period. The success rate was 63% (75% for multiparous and 53% for nulliparous women). There was no significant complication. On univariate analysis, predictors of successful external cephalic version were: multiparity, unengaged presenting part, higher amniotic fluid index (≥ 10 cm), thin abdominal wall, low uterine tone, and easily palpable fetal head (subjective assessment by practitioners before external cephalic version). On multivariate analysis, only multiparity, non-engagement of the fetal buttock and thin maternal abdomen were associated with successful external cephalic version. In all, 69% of those who had successful external cephalic version succeeded in the first roll (P<0.001), and 82% of the women with successful external cephalic versions had vaginal deliveries (93% in multiparous and 69% in nulliparous women). Uptake rate of external cephalic version was studied in the latter part of the study period (2006-2009). Whilst 735 women were eligible for external cephalic version, 131 women chose to have the procedure resulting in an uptake rate of 18%. External cephalic version was effective in reducing breech presentations at term and corresponding caesarean section rates, but the uptake rate was low. Further work should address the barriers to the low acceptance of external cephalic version. The results of this study could encourage women to opt for external cephalic version.

Summary A 6-yr-old boy was the victim of a burns accident in a public bathhouse. The burns involved the face, neck, upper and lower extremities, anterior and posterior trunk, and both buttocks, covering 72% of the total body surface area (TBSA). The lesions in the lower extremities and parts of the right upper extremity were deep partial-thickness, comprising 40% TBSA. On day 5 post-burn, the lesions in both lower extremities were excised to the extent of the fascia under general anaesthesia. Meshed J1 Jayya Acellular Dermis®, a kind of acellular allodermal (ADM) matrix, was then placed on the left knee joint. The right knee joint served as control. The wounds in both lower extremities were then overlaid with microskin autografting. At 19 days post-application, the lesions in both lower extremities had almost completely resurfaced. Follow-up at six months revealed well-healed and stable skin of acellular ADM and microskin autografts on the left knee. However, the skin of the right knee was unstable and there was a chronic residual ulcer. Both legs showed some significant hypertrophic scars. The left knee joint (acellular ADM grafted site) showed mild contractures, while the right knee joint developed a significant contracture. The "skin" of the co-graft covered site appeared thicker and more elastic. The movement range of the left knee joint was much larger than that of the right knee joint. These results suggest that co-graft of acellular dermal matrix and autogenous microskin may be an effective way to repair this functional site in children with extensive burns and to improve the functional and cosmetic results.

PurposeTo evaluate the efficacy and safety of a novel retrograde transvenous embolization technique of peripheral arteriovenous malformations (AVMs) using Onyx.Materials and MethodsWe conducted a retrospective analysis of all patients who underwent transvenous retrograde Onyx embolization of peripheral AVMs with dominant venous outflow over a 29-month period. The embolization is aimed at retrograde filling of the nidus after building a solid plug in the dominant venous outflow (push-through). Classification, clinical signs, technical aspects, clinical and technical success rates, and complications were recorded. Short-term outcome was assessed.Results11 Symptomatic patients (8 female; mean age 31.4 years) were treated at our Vascular Anomalies Center withmore » this method between January 2012 and May 2014. The AVMs were located on the upper extremity (n = 3), pelvis (n = 2), buttock (n = 2), and lower extremity (n = 4). Retrograde embolization was successfully carried out after preparatory transarterial-flow reduction in eight cases (73 %) and venous-flow reduction with Amplatzer Vascular Plugs in four cases (36 %). Complete devascularization (n = 10; 91 %) or 95 % devascularization (n = 1; 9 %) led to complete resolution (n = 8; 73 %) or improvement of clinical symptoms (n = 3; 27 %). One minor complication occurred (pain and swelling). During a mean follow-up time of 8 months, one clinically asymptomatic recurrence of AVM was detected.ConclusionInitial results suggest that retrograde transvenous Onyx embolization of peripheral AVMs with dominant venous outflow is a safe and effective novel technique with a low complication rate.« less

Piriformis syndrome is a pain syndrome originating in the buttock and is attributed to 6% - 8% of patients referred for the treatment of back and leg pain. The treatment for piriformis syndrome using fluoroscopy, computed tomography (CT), electromyography (EMG), and ultrasound (US) has become standard practice. The treatment of Piriformis Syndrome has evolved to include fluoroscopy and EMG with CT guidance. We present a case study of 5 successful piriformis injections using 3-D computer-assisted electromagnet needle tracking coupled with ultrasound. A 6-degree of freedom electromagnetic position tracker was attached to the ultrasound probe that allowed the system to detect the position and orientation of the probe in the magnetic field. The tracked ultrasound probe was used to find the posterior superior iliac spine. Subsequently, 3 points were captured to register the ultrasound image with the CT or magnetic resonance image scan. Moreover, after the registration was obtained, the navigation system visualized the tracked needle relative to the CT scan in real-time using 2 orthogonal multi-planar reconstructions centered at the tracked needle tip. Conversely, a recent study revealed that fluoroscopically guided injections had 30% accuracy compared to ultrasound guided injections, which tripled the accuracy percentage. This novel technique exhibited an accurate needle guidance injection precision of 98% while advancing to the piriformis muscle and avoiding the sciatic nerve. The mean (± SD) procedure time was 19.08 (± 4.9) minutes. This technique allows for electromagnetic instrument tip tracking with real-time 3-D guidance to the selected target. As with any new technique, a learning curve is expected; however, this technique could offer an alternative, minimizing radiation exposure.

Myoelectric Response of Back Muscles to Vertical Random Whole-Body Vibration with Different Magnitudes at Different Postures

2002-05-01

Back muscle forces contribute essentially to the whole-body vibration-induced spinal load. The electromyogram (EMG) can help to estimate these forces during whole-body vibration (WBV). Thirty-eight subjects were exposed to identical random low-frequency WBV (0·7, 1·0 and 1·4 m/s-2 r.m.s. weighted acceleration) at a relaxed, erect and bent forward postures. The acceleration of the seat and the force between the seat and the buttocks were measured. Six EMGs were derived from the right side of the m. trapezius pars descendens, m. ileocostalis lumborum pars thoracis, m. ileocostalis lumborum pars lumborum; m. longissimus thoracis pars thoracis, m. longissimus thoracis pars lumborum, and lumbar multifidus muscle. All data were filtered for anti-aliasing and sampled with 1000 Hz. Artefacts caused by the ECG in the EMG were identified and eliminated in the time domain using wavelets. The individually rectified and normalized EMGs were averaged across subjects. The EMGs without WBV exhibited characteristic patterns for the three postures examined. The coherence and transfer functions indicated characteristic myoelectric responses to random WBV with several effects of posture and WBV magnitude. A comprehensive set of transfer functions from the seat acceleration or the mean normalized input force to the mean processed EMG was presented.The results can be used for the development of more sophisticated models with a separate control of various back muscle groups. However, the EMG-force relationship under dynamic conditions needs to be examined in more detail before the results can be implemented. Since different reflex mechanisms depending on the frequency of WBV are linked with different types of active muscle fibres, various time delays between the EMG and muscle force may be necessary.

The combination of clinical items suggestive of inflammatory back pain has proved useful for early identification of patients with axial SpA (axSpA) in primary care. However, whether HLA B27 contributes to that is unclear, and published recommendations have advised against it. In this study, we reanalysed data of that trial in relation to the HLA B27 results. Consecutive patients <45 years old (n = 950) with back pain (BP) >2 months presenting to 143 orthopaedists were referred to 36 rheumatologists who made the diagnosis. The predictive value of HLA B27 (n = 298) alone and in combination, including modelling and a two-step strategy, was calculated. Among all patients (mean age 36 years, 52% female, median duration of BP 32 months), 107 had axSpA (36%). Using a simple model, HLA B27 alone performed better than all combinations of clinical items and adding it did not improve likelihood ratios (LRs). Using modelling, two-phase strategies were analysed. Additional items were only relevant in the HLA B27-negative group: improvement by movement, buttock pain and psoriasis. Combining this information revealed the presumably best strategy to predict axSpA in primary care: more than one of these items or HLA B27 need to be present (sensitivity 80.4%, specificity 75.4%, LR+ 3.27 and LR- 0.26). This is the first study to show that patients with axSpA are more reliably identified in primary care by a strategy that includes HLA B27. Because of the two-step approach, the test needs to be performed in only about half of patients with chronic BP.

The study was done to assess the magnitude of problems of metabolic syndrome among obese adolescents. It was a cross-sectional study done from January 2013 to June 2014 in paediatric endocrine outpatient department in BIRDEM General Hospital, Dhaka, Bangladesh. Total 172 adolescents having exogenous obesity aged 10-18 years were included. Impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and type 2 diabetes mellitus (DM) were defined as per WHO criteria.The adolescents having Body Mass Index (BMI) ≥95th centile were classified as obese.Waist circumference was measured at the level midway between the lower rib margin & the iliac crest, at the level of umbilicus with the person breathing out gently in centimeter. Hip circumference was measured at the maximum width over the buttocks at the level of the greater trochanters in centimeter. Among 172 obese adolescents, metabolic syndrome was found in 66 patients (38.4%). The commonest metabolic abnormality among those having metabolic syndrome was low HDL level (77.3%) followed by high triglyceride level(71.2%). Glucose intolerance (IFG and/or IGT) was found in 16.7%, Type 2 DM in 10.6%, systolic hypertension in 10.7% and diastolic hypertension in 12.1%. Triglyceride (p = 0.042) and Cholesterol level (p = 0.016) were significantly higher and HDL-cholesterol level (p = 0.000) was significantly lower among obese adolescents having metabolic syndrome. Less physical activity (p = 0.04) was significantly related to the development of metabolic syndrome. On logistic regression analysis male sex, family history of obesity and low HDL-cholesterol correlated to metabolic syndrome. The High rate of metabolic syndrome among obese adolescents is alarming.

To investigate whether pigmentation genes involved in the melanogenic pathway (melanogenesis) contributed to melanoma predisposition, we compared pigmentary genetics with quantitative skin pigmentation measurements, the number of atypical nevi, the total nevus count, and the familial atypical multiple mole and melanoma (FAMMM) syndrome. We typed 32 pigmentary SNP markers and sequenced MC1R in 246 healthy individuals and 116 individuals attending periodic control for malignant melanoma development, 50 of which were diagnosed with FAMMM. It was observed that individuals with any two grouped MC1R variants (missense, NM_002386:c. 456C > A (p.TYR152*), or NM_002386:c.83_84insA (p.Asn29Glnfs*14) had significantly (p<0.001) lighter skin pigmentation of the upper-inner arm than those with none or one MC1R variant. We did not observe any significant association of the MC1R variants with constitutive pigmentation measured on the buttock area. We hypothesize that the effect of MC1R variants on arm pigmentation is primarily reflecting the inability to tan when subjected to UVR. A gender specific effect on skin pigmentation was also observed, and it was found that the skin pigmentation of females on average were darker than that of males (p<0.01). We conclude that MC1R variants are associated with quantitative skin colour in a lightly pigmented Danish population. We did not observe any association between any pigmentary marker and the FAMMM syndrome. We suggest that the genetics of FAMMM is not related to the genetics of the pigmentary pathway. PMID:26938746

Senile gluteal dermatosis (SGD) is a common genital dermatosis but has gained little attention before. A large-scale clinical study of this disease is lacking. We examined 162 consecutive outpatients with gluteal skin diseases of different causes. Fourteen skin biopsies were performed. Patient's age, gender, body mass index (BMI), way of sitting or lying, treatment response, and underlying systemic diseases were recorded. About 137 (85%) patients could be defined as SGD. These patients, with a mean age of 79.4 ± 40.7 years and a mean BMI of 21.7 ± 10.8, presented with either partial (n = 43, 31%) or full-blown (n = 94, 69%) SGD lesions characterized by the sign of so-called "three corners of a triangle": brownish plaques on the gluteal cleft and each side of the buttocks. Male/female ratio was 130/7. Itching or pain of varying intensity was reported by 50 patients (36%) and 14 patients (10%), respectively. Eighty-six patients (53%) presented with horizontal hyperkeratotic ridges, a characteristic sign of SGD. Most patients spent most of the day sitting but reported no special way of sitting or lying. More than half of patients with SGD claimed no response to topical steroids and/or keratolytics. In comparison with patients with SGD, SGD-free patients were younger (61.3 ± 36 years, P = 0.0005) and heavier (BMI 26.2 ± 15.6, P < 0.0001) but showed no significant difference in the frequency of underlying systemic diseases. SGD is a common dermatosis, mostly affecting the thinner elderly. Friction, pressures and long hours sitting seemed to be important factors to trigger this dermatosis. © 2013 The International Society of Dermatology.

Fifteen million U.S. patients each year seek medical care abroad; however, there are no data on outcomes and follow-up of these procedures. This study aims to identify, evaluate, and survey patients presenting with complications from aesthetic procedures abroad and estimate their cost to the U.S. health care system. A single-center retrospective review was conducted. A cohort of patients presenting with complications from aesthetic procedures performed abroad was generated. Demographic, complication, and cost data were compiled. Patients were surveyed to assess their overall experience. Over a 36-month period, 42 patients met inclusion criteria (one man and 41 women), with an average age of 35 ± 11.4 years (range, 20 to 60 years). Comorbidities included four active smokers, two patients with hypertension, and one patient with diabetes. Average body mass index was 29 ± 4.4 kg/m (range, 22 to 38 kg/m). Procedures performed abroad included abdominoplasty (n = 28), liposuction (n = 20), buttock augmentation (n = 10), and breast augmentation (n = 7), with several patients undergoing combined procedures. Eleven patients presented with abscesses and eight presented with wound dehiscence. Eight of the 18 patients who were surveyed were not pleased with their results and 11 would not go abroad again for subsequent procedures. Average cost of treating the complications was $18,211, with an estimated cost to the U.S. health care system of $1.33 billion. The main payer group was Medicaid. Complications from patients seeking aesthetic procedures abroad will continues to increase. Patients should be encouraged to undergo cosmetic surgery in the United States to improve patient outcomes and satisfaction and because it is economically advantageous. Therapeutic, IV.

Adiponectin expression in subcutaneous adipose tissue is reduced in women with cellulite.

Cellulite, which appears as orange peel-type or cottage cheese-like dimpling of the skin on the thighs and buttocks, is a complex, multifactorial, cosmetic disorder of the subcutaneous fat layer and the overlying superficial skin. Adiponectin is an adipocyte-derived hormone mainly produced by subcutaneous fat that shows important protective anti-inflammatory and vasodilatory effects. We hypothesized that adiponectin expressed in the subcutaneous adipose tissue (SAT) might play a role in the pathogenesis of cellulite. We reasoned that a reduction in the expression of adiponectin - a humoral vasodilator - in the SAT of cellulite areas might contribute to the altered microcirculation frequently found in these regions. A total of 15 lean (body mass index [BMI] < 25 kg/m(2) ) women with cellulite and 15 age- and BMI-matched women without cellulite participated in this study. Real-time reverse transcription polymerase chain reaction (RT-PCR) was used to assess adiponectin gene expression. Plasma adiponectin levels were measured using a commercial enzyme immunoassay kit. Adiponectin mRNA expression in the SAT of the gluteal region was significantly lower in areas with cellulite compared with those without (12.6 ± 3.1 AU versus 16.6 ± 4.1 AU; P=0.006). However, plasma adiponectin levels did not differ between women with (20.3 ± 7.3 μg/ml) and without (19.3 ± 6.1 μg/ml) cellulite (P=0.69). Adiponectin expression is significantly reduced in the SAT in areas affected by cellulite. Our findings provide novel insights into the nature of cellulite and may give clues to the treatment of this cosmetic issue. © 2011 The International Society of Dermatology.

This study examined the psychometric properties of the Bahasa Malaysia (BM) version of the European Organization for Research and Treatment of Cancer (EORTC) Colorectal Cancer-specific Quality Of Life Questionnaire (QLQ-CR29). We studied 93 patients recruited from University Malaya and Universiti Kebangsaan Medical Centers, Kuala Lumpur, Malaysia using a self-administered method. Tools included QLQ-C30, QLQ-CR29 and Karnofsky Performance Scales (KPS). Statistical analyses included Cronbach's alpha, test-retest correlations, multi-traits scaling and known-groups comparisons. A p value ≤ 0.05 was considered significant. The internal consistency coefficients for body image, urinary frequency, blood and mucus and stool frequency scales were acceptable (Cronbach's alpha α ≥ 0.65). However, the coefficients were low for the blood and mucus and stool frequency scales in patients with a stoma bag (α = 0.46). Test-retest correlation coefficients were moderate to high (range: r = 0.51 to 1.00) for most of the scales except anxiety, urinary frequency, buttock pain, hair loss, stoma care related problems, and dyspareunia (r ≤ 0.49). Convergent and discriminant validities were achieved in all scales. Patients with a stoma reported significantly higher symptoms of blood and mucus in the stool, flatulence, faecal incontinence, sore skin, and embarrassment due to the frequent need to change the stoma bag (p < 0.05) compared to patients without stoma. None of the scales distinguished between patients based on the KPS scores. There were no overlaps between scales in the QLQ-C30 and QLQ-CR29 (r < 0.40). the BM version of the QLQ-CR29 indicated acceptable psychometric properties in most of the scales similar to original validation study. This questionnaire could be used to complement the QLQ-C30 in assessing HRQOL among BM speaking population with colorectal cancer.

Treatment of severe aortoiliac occlusive disease (AIOD) frequently requires long-segment stenting of the common and external iliac arteries (CIA and EIA, respectively). This study aims to analyze the patency of the internal iliac artery (IIA) after placement of a CIA and EIA stents across the orifice. A retrospective analysis of all patients who underwent de novo ipsilateral stent placement in the CIA and EIA between 2006 and 2013 was performed. Kaplan-Meier analysis was used to analyze patency of the IIA, and Cox proportional hazard models were used to identify characteristics associated with occlusion. We identified 77 patients and 93 limbs where ipsilateral CIA and EIA stents were placed. Preintervention angiographic review found 52 cases of a patent ipsilateral IIA where stents were placed across the origin of the IIA in 31 cases and staggered across the orifice in 20 limbs. Kaplan-Meier analysis demonstrated a 37% patency in limbs where the stent covered the IIA orifice compared to 78% patency in uncovered arteries (P = 0.04). New-onset buttock claudication developed in 4 patients, 2 with patent IIAs and 2 with occluded. New-onset impotence also developed in 3 patients with occluded IIA and 5 patients with patent IIAs. Placement of stents across the origin of the IIA may not result in immediate occlusion, but long-term patency of covered IIAs is decreased compared to uncovered IIAs. This study is limited by a small sample size, but when treating AIOD, coverage of the internal iliac origin should be avoided to maintain patency of the pelvic circulation.

2017-01-01

The incidence of fragility fractures of the pelvis is increasing quickly. The characteristics of these fractures are different from pelvic ring disruptions in adults. Fragility fractures of the pelvis are the consequence of a low-energy trauma which occurs in a patient with an important decrease of bone mineral density. Due to a consistent pattern of alteration of bone mass distribution in the sacrum, other fracture morphologies occur than in younger adults. The leading symptom is immobilizing pain in the lower back, in the buttocks, in the inguinal region and/or at the pubic symphysis. Conventional radiographs and CT will show the presence and localization of the fractures in the anterior and posterior pelvic ring. A new, comprehensive classification system distinguishes four categories of instability. This first criterion is most important, because it also gives hints for the preferred type of treatment. The second criterion, leading to the subtypes in the four categories, is the localization of the instability in the posterior pelvic ring. This criterion points the way towards the type of the surgical procedure to be used. When a surgical treatment is chosen, the procedure should be as minimal invasive as possible. Different techniques for percutaneous or less invasive fixation of the posterior pelvic ring have been developed. Their advantages and limitations are presented: sacroplasty, iliosacral screw osteosynthesis, cement augmentation, transiliac internal fixation, trans-sacral osteosynthesis, lumbopelvic fixation. Fractures of the anterior pelvic ring also need special attention. Retrograde transpubic screw fixation is recommended for pubic rami fractures. Fractures of the pubic body and instabilities of the pubic symphysis need bridging plate osteosynthesis. We do not recommend anterior pelvic external fixation in elderly because of the risk of pin track infection and pin loosening. Celsius.

Sacroiliac joint tuberculosis(SJT) is relatively uncommon, but it may cause severe sacroiliac joint destruction and functional disorder. Few studies in the literature have been presented on SJT, reports of surgical treatment for SJT are even fewer. In this study, we retrospectively reviewed surgical management of patients with severe SJT of 3 different types and proposed to reveal the clinical manifestations and features and aim to determine the efficiency and security of such surgical treatment. We reviewed 17 patients with severe SJT of 3 different types who underwent posterior open-window focal debridement and bone graft for joint fusion. Among them,five patients with anterior sacral abscess had anterior abscess curettage before debridement. Two patients with lumbar vertebral tuberculosis received one-stage posterior tuberculous debridement, interbody fusion and instrumentation. Follow-up was performed 36 months (26 to 45 months) using the following parameters: erythrocyte sedimentation rate(ESR), status of joint bony fusion on CT scan, visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Buttock pain and low back pain were progressively relieved with time. 6 months later, pain was not obvious, and ESR resumed to normal levels within 3 months. Solid fusion of the sacroiliac joint occurred within 12 months in all cases. No complications or recurrence occurred. At final follow-up, all patients had no pain or only minimal discomfort over the affected joint and almost complete functional recovery. Posterior open-window focal debridement and joint fusion is an efficient and secure surgical method to treat severe SJT. If there is an abscess in the front of the sacroiliac joint, anterior abscess curettage should be performed as a supplement.

Onchocerciasis is caused by Onchocerca volvulus and mainly leads to pruritus and skin and visual disorders, including blindness. Seventeen million people are infected in 38 countries; 31 of these are in sub-Saharan Africa, six in Latin America and one on the Arabian Peninsula. More than 99% of cases occur in sub-Saharan Africa where 120 million people are at risk of infection. Eye disorders have been well-documented; however, skin disorders have not been described accurately. The objective of our study was to describe the epidemiology, main skin manifestations and treatment of imported onchocerciasis. A retrospective study was thus conducted by analysing the main demographic, clinical and treatment data regarding a cohort of 400 patients attending a reference clinical unit over a 17-year period. Most patients were female (55%) with mean age 37.5±16.7 years. All the migrants came from sub-Saharan countries. The most frequently occurring dermatological symptom was pruritus. Ivermectin had been used as first-line therapy and adverse reactions had been described in 11 patients (3.2%). The results indicate the fact that there should be a clinical suspicion of onchocerciasis regarding immigrants from endemic areas having skin lesions compatible with the disease's profile or asymptomatic patients having eosinophilia or unexplained high IgE. Moreover, skin snips from the buttocks region were very fruitful and treatment with ivermectin was seen to be safe. This is the largest case series regarding imported onchocerciasis described up to the present time.

To evaluate the therapeutic effect and safety of ultrasound-guided high-intensity focused ultrasound (USgHIFU) treatment on symptomatic uterine fibroids in Black women. A feasibility study. Gynaecological department in a teaching hospital in South Africa. Premenopausal women with uterus fibroids. Twenty-six patients with 53 fibroids who underwent USgHIFU treatment were enrolled. The USgHIFU treatment information was recorded, including treatment time, sonication time and total energy. Adverse events were also observed and recorded during and after treatment. Safety and efficacy of USgHIFU for the treatment of uterine fibroids in Black women. The median volume of fibroids was 52.7 (interquartile range, 18.6-177.4) cm 3 . According to USgHIFU treatment plan, total energy of 298.6 ± 169.3 kJ (range, 76.0-889.2) within treatment time of 90.3 ± 43.3 minutes (range, 14.0-208.0), in which sonication time of 774.0 ± 432.9 seconds (range, 190.0-2224.0) was used to ablate fibroids. The average ablation rate was 80.6 ± 9.7% (range, 46.5-94.5%). During the procedure, 69.2% of the patients reported lower abdominal pain, 57.7% sciatic/buttock pain, 38.5% burning skin, and 34.6% transient leg pain. No severe complications were observed. USgHIFU is feasible and safe to use to treat symptomatic uterine fibroids in Black women. Multiple uterine fibroids are more frequently detected in Black women.

To describe differences in in-seat behavior observed between individuals with a spinal cord injury (SCI) with and without a history of recurrent pressure injuries. Cross-sectional cohort study. General community. Twenty-nine adults more than 2 years post SCI, who used a wheelchair as their primary mobility device and had the ability to independently perform weight shift maneuvers. Participants were grouped according to whether or not they had a history of recurrent pressure injuries (PrIs), with 12 subjects having had two or more pressure injuries in the pelvic area (PrI Group). Not applicable. Daily time in wheelchair, number of transfers, and frequency of pressure reliefs (full unloading), weight shifts (30% load reduction), and in-seat movements (transient center of pressure movements or unloading). The median participant spent 10.3 hours in his wheelchair and performed 16 transfers to or from the wheelchair daily. Pressure reliefs were performed less than once every 3 hours in both groups. Weight shifts were performed significantly more often by the No PrI Group (median (interquartile range) 2.5 (1.0-3.6) per hour) than the PrI Group (1.0 (0.4-1.9), with P = 0.037 and effect size r = 0.39). In-seat movements were performed 46.5 (28.7-76.7) times per hour by the No PrI group and 39.6 (24.3-49.7) times per hour for the PrI group (P = 0.352, effect size r = 0.17). Weight shifts that can be produced by functional activities and that partially unload the buttocks should be considered as an important addition to individuals' PrI prevention regimen.

The present study was carried out to evaluate the possible association between obesity and periodontitis in patients with DS, and to explore which measure of obesity is most closely correlated to periodontitis. A prospective observational study was made to determine whether obesity is related to periodontal disease in patients with DS. The anthropometric variables were body height and weight, which were used to calculate BMI and stratify the patients into three categories: < 25(normal weight), 25-29.9 (overweight) and ≥ 30.0 kg/m2 (obese). Waist circumference and hip circumference in turn was recorded as the greatest circumference at the level of the buttocks, while the waist/hip ratio (WHR) was calculated. Periodontal evaluation was made of all teeth recording the plaque index (PI), pocket depth (PD), clinical attachment level (CAL) and the gingival index. We generated a multivariate linear regression model to examine the relationship between PD and the frequency of tooth brushing, gender, BMI, WHI, WHR, age and PI. Significant positive correlations were observed among the anthropometric parameters BMI, WHR, WHI and among the periodontal parameters PI, PD, CAL and GI. The only positive correlation between the anthropometric and periodontal parameters corresponded to WHR. Upon closer examination, the distribution of WHR was seen to differ according to gender. Among the women, the correlation between WHR and the periodontal variables decreased to nonsignificant levels. In contrast, among the males the correlation remained significant and even increased. In a multivariate linear regression model, the coefficients relating PD to PI, WHR and age were positive and significant in all cases. Our results suggest that there may indeed be an association between obesity and periodontitis in male patients with DS. Also, we found a clear correlation with WHR, which was considered to be the ideal adiposity indicator in this context.

Case Report. The purpose of this case report is to describe the clinical reasoning process involved with the differential diagnosis and management of a 69 year-old male runner reporting a six month history of insidious onset of left sided low back and buttock pain of low to medium degree of irritability. The case presented describes the utilization of clinical reasoning by a clinician in fellowship training when a patient with atypical adverse neurodynamic dysfunction related to running was encountered. The patient's physical examination was relatively unremarkable. Assessment of the patient's subjective history, self-report measures [Oswestry Disability Index (ODI), global rating of change scale (GROC)], objective findings, and tests and measures led to a working diagnosis of atypical adverse peripheral neurodynamic dysfunction. The lumbar spine, sacroiliac joint, hip joint and lower extremity were ruled out by a comprehensive subjective and objective examination. The diagnosis of adverse neurodynamic dysfunction became a diagnosis of exclusion. Returning two and a half weeks after initial evaluation the patient reported no pain with running. Twelve weeks after the initiation of physical therapy, the patient was contacted via email. He was sent, and asked to fill out an ODI. The patient demonstrated an improvement in ODI from 10% to 2%. He also reported that he continued to run after treatment without pain. Determining the source of a patient complaint can occasionally be an arduous undertaking. Pathological sources of a patient's symptoms may not be easily determined. Development of differential diagnosis and clinical reasoning skills is imperative. Improving clinical reasoning skills requires deliberate practice through reflective thinking before, during, and after patient interactions. Refinement of these skills leads to the primary goal of identifying the patient's clinical presentation, thus matching it with the most effective treatment approach. Level 4.

It has been emphasized by many authors that to obtain better aesthetic results in a burned facial area to be resurfaced - if it extends into more than one aesthetic territory - the units involved should be combined into a single large composite unit allowing the largest possible skin graft to be used. Unfortunately, the donor site for full-thickness grafts is limited in young patients and hence tissue expansion is used. A monoblock expanded full-thickness skin graft for facial resurfacing after post-burn sequelae excision was used in 12 young patients after expansion of the superolateral aspect of the buttock. Females made up the majority of the patients (75%) and the ages ranged between 8 and 18 yr. The operating time was 3-3.5 hours, in two sessions. Post-operatively, we recorded partial graft necrosis in two cases (16.7%) and infection in one (8.3%), and some minor donor-site-related complications were reported, such as haematoma in one patient (8.3%), wound infection in one patient (8.3%), and wide scarring in two patients (16.7%). At follow-up, eight of the patients (66.7%) were satisfied with their new facial look as the mask effect of facial scarring had been overcome. With monoblock expanded full-thickness graft we were able to resurface the face in nine cases (75%). A second complementary procedure to reconstruct the eyebrows or reshape the nose was required in two cases (16.7%). We concluded that the monoblock expanded full-thickness graft was a suitable solution for limitation of the donor site in young patients, as the resulting wound could be closed primarily with a scar that could be concealed by the underwear, with lim.

Sustained pressure, shear forces, and friction, as well as elevated humidity/moisture, are decisive physical factors in the development of pressure injuries (PIs). To date, further research is needed in order to understand the influence of humidity and moisture on the coefficient of friction (COF) of skin against different types of medical textiles. The aim of this work was to investigate the effects of moisture caused by sweat, urine, or saline on the resulting COF of skin against different textiles used in the medical setting in the context of PI prevention. For that purpose, we performed physical measurements of static COFs of porcine skin followed by finite element (FE) computational modelling in order to illustrate the effect of increased COF at the skin on the resulting strains and stresses deep within the soft tissues of the buttocks. The COF of dry skin obtained for the 3 textiles varied between 0.59 (adult diaper) and 0.91 (polyurethane dressing). In addition, the COF increased with the added moisture in all of the tested cases. The results of the FE simulations further showed that increased COF results in elevated strain energy density and shear strain values in the skin and deeper tissues and, hence, in an increased risk for PI development. We conclude that moisture may accelerate PI formation by increasing the COF between the skin and the medical textile, regardless of the type of the liquid that is present. Hence, reduction of the wetness/moisture between the skin and fabrics in patients at a high risk of developing PIs is a key measure in PI prevention. © 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Background Gender is a critically important moderator of psychopathology. However, gender similarities and differences in body dysmorphic disorder (BDD) have received scant investigation. In this study, we examined gender similarities and differences in the broadest sample in which this topic has been examined. Methods Two hundred subjects with BDD recruited from diverse sources were assessed with a variety of standard measures. Results There were more similarities than differences between men and women, but many gender differences were found. The men were significantly older and more likely to be single and living alone. Men were more likely to obsess about their genitals, body build, and thinning hair/balding; excessively lift weights; and have a substance use disorder. In contrast, women were more likely to obsess about their skin, stomach, weight, breasts/chest, buttocks, thighs, legs, hips, toes, and excessive body/facial hair, and they were excessively concerned with more body areas. Women also performed more repetitive and safety behaviors, and were more likely to camouflage and use certain camouflaging techniques, check mirrors, change their clothes, pick their skin, and have an eating disorder. Women also had earlier onset of subclinical BDD symptoms and more severe BDD as assessed by the Body Dysmorphic Disorder Examination. However, men had more severe BDD as assessed by the Psychiatric Status Rating Scale for Body Dysmorphic Disorder, and they had poorer Global Assessment of Functioning Scale scores, were less likely to be working because of psychopathology, and were more likely to be receiving disability, including disability for BDD. Conclusions The clinical features of BDD in men and women have many similarities but also some interesting and important differences. These findings have implications for the detection and treatment of BDD. PMID:16490564

Hand, foot, and mouth disease (HFMD) remains a common problem in India, yet its etiology is largely unknown as diagnosis is based on clinical characteristics. There are very few laboratory-based molecular studies on HFMD outbreaks. The aim of this study was to characterize HFMD-related isolates by molecular techniques. Between 2005 and 2008, during two documented HFMD outbreaks, 30 suspected HFMD cases presented at the Outpatient Unit of the Department of Dermatology, Christian Medical College (CMC), Vellore. Seventy-eight clinical specimens (swabs from throat, mouth, rectum, anus, buttocks, tongue, forearm, sole, and foot) were received from these patients at the Department of Clinical Virology, CMC, for routine diagnosis of hand, foot, and mouth disease. Samples from these patients were cultured in Vero and rhabdomyosarcoma (RD) cell lines. Isolates producing enterovirus-like cytopathogenic effect (CPE) in cell culture were identified by a nested reverse transcription-based polymerase chain reaction (RT-PCR) and sequenced. The nucleotide sequences were analyzed using the BioEdit sequence program. Homology searches were performed using the Basic Local Alignment Search Tool (BLAST) algorithm. The statistical analysis was performed using Epi Info version 6.04b and Microsoft Excel 2002 (Microsoft Office XP). Of the 30 suspected HFMD cases, only 17 (57%) were laboratory confirmed and Coxsackievirus A16 (CVA16) was identified as the etiological agent in all these cases. Coxsackievirus A16 (CVA16) was identified as the virus that caused the HFMD outbreaks in Vellore between 2005 and 2008. Early confirmation of HFMD helps to initiate control measures to interrupt virus transmission. In the laboratory, classical diagnostic methods, culture and serological tests are being replaced by molecular techniques. Routine surveillance systems will help understand the epidemiology of HFMD in India.

Body dysmorphic disorder (BDD) is a distressing psychiatric disorder. So far there have not been any studies on BDD in Saudi Arabia. The aim of this study was to determine the prevalence of body dysmorphic disorder in female medical students and to investigate whether there is an association between BDD and body features of concern, social anxiety and symptoms of BDD. A cross sectional study was carried out on female medical students of the college of medicine, King Saud University, Riyadh, Saudi Arabia during January to April, 2015. Data were collected using the body image disturbance questionnaire, Body dysmorphic disorder symptomatology and social interaction anxiety scale. Descriptive statistics, bivariate and multivariate analysis were used to analyze the results. Out of 365 students who filled out the questionnaire, 4.4% (95% confidence intervals (CI): 2.54% to 7.04%) were positive for BDD with skin (75%) and fat (68.8%) as the most frequent body features of concern. Ten features (skin, fat, chest, hips, buttocks, arms, legs, lips, fingers, and shoulders) out of twenty-six were significantly associated with BDD. Arms and chest were independently associated with BDD. The odds of presence of body concern related to "arms" was 4.3 (95% C.I: 1.5, 12.1) times more in BDD subjects than non-BDD subjects, while concern about "chest" was 3.8 (1.3, 10.9) times more when compared to non-BDD subjects. No statistically significant association was observed between BDD and social anxiety (P = 0.13). This was the first study conducted in Kingdom of Saudi Arabia (KSA) on female medical students, which quantified the prevalence of BDD and identified the body features associated with it. Body dysmorphic disorder is prevalent in female medical students but it is relatively rare and an unnoticed disorder.

Accurate determination of walking capacity is important for the clinical diagnosis and management plan for patients with peripheral arterial disease. The current "gold standard" of measurement is walking distance on a treadmill. However, treadmill testing is not always reflective of the patient's natural walking conditions, and it may not be fully accessible in every vascular clinic. The objective of this study was to determine whether Google Maps, the readily available GPS-based mapping tool, offers an accurate and accessible method of evaluating walking distances in vascular claudication patients. Patients presenting to the outpatient vascular surgery clinic between November 2013 and April 2014 at the Ottawa Hospital with vasculogenic calf, buttock, and thigh claudication symptoms were identified and prospectively enrolled in our study. Onset of claudication symptoms and maximal walking distance (MWD) were evaluated using four tools: history; Walking Impairment Questionnaire (WIQ), a validated claudication survey; Google Maps distance calculator (patients were asked to report their daily walking routes on the Google Maps-based tool runningmap.com, and walking distances were calculated accordingly); and treadmill testing for onset of symptoms and MWD, recorded in a double-blinded fashion. Fifteen patients were recruited for the study. Determination of walking distances using Google Maps proved to be more accurate than by both clinical history and WIQ, correlating highly with the gold standard of treadmill testing for both claudication onset (r = .805; P < .001) and MWD (r = .928; P < .0001). In addition, distances were generally under-reported on history and WIQ. The Google Maps tool was also efficient, with reporting times averaging below 4 minutes. For vascular claudicants with no other walking limitations, Google Maps is a promising new tool that combines the objective strengths of the treadmill test and incorporates real-world walking environments.

Giant cell tumor of bone (GCTB) is commonly treated with surgery; however, surgery of GCTB in the sacrum may be challenging due to the associated risk. A conservative approach may be selective arterial embolization or zoledronic acid (ZOL) treatment; however, there are currently no studies investigating the efficacy of combining these two treatments. Denosumab may also be used; however, to the best of our knowledge, there are no reports of a stepwise approach for the use of all three treatments in a single patient. We herein present such a case. A 32-year-old woman diagnosed with sacral GCTB was treated with selective arterial embolization for 3 months. No improvement was observed, and monthly infusions of ZOL were added (administered 2 weeks after each arterial embolization treatment). Ten months after the initiation of ZOL, there was still no improvement. The therapy was changed to denosumab 120 mg, injected subcutaneously once a month. By the third dose, the buttock pain had decreased and the patient became ambulatory. At 5 and 10 months, computed tomography scans revealed bone sclerosis gradually appearing around the sacrum. By 1 year, needle biopsy detected no neoplastic cells. At that point, the patient discontinued treatment, as there was hepatic function impairment due to a history of hepatitis B. Despite treatment discontinuation, the patient exhibited no further symptoms, there were no signs of progression on radiography, and surgery was not required. Our patient experienced treatment failure with selective arterial embolization. The combination of ZOL with selective arterial embolization also did not improve the patient's condition. Denosumab was found to be superior to both treatments, achieving tumor remission. The patient remains symptom- and disease-free. Further studies are required, but our results suggest that patients with unresectable GCTB who fail to respond to selective arterial embolization may benefit from denosumab treatment, but not from combination therapy with selective arterial embolization and ZOL.

Objective: Intensified preoperative treatments have been increasingly investigated in locally advanced rectal cancer (LARC), but limited data are available for the impact of these regimens on quality of life (QoL) and bowel function (BF). We assessed these outcome measures in EXPERT-C, a randomized phase 2 trial of neoadjuvant capecitabine combined with oxaliplatin (CAPOX), followed by chemoradiation therapy (CRT), total mesorectal excision, and adjuvant CAPOX with or without cetuximab in magnetic resonance imaging-defined, high-risk LARC. Methods and Materials: QoL was assessed using the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR29 questionnaires. Bowel incontinence was assessed using the modifiedmore » Fecal Incontinence Severity Index questionnaire. Results: Compared to baseline, QoL scores during preoperative treatment were better for symptoms associated with the primary tumor in the rectum (blood and mucus in stool, constipation, diarrhea, stool frequency, buttock pain) but worse for global health status, role functioning, and symptoms related to the specific safety profile of each treatment modality. During follow-up, improved emotional functioning and lessened anxiety and insomnia were observed, but deterioration of body image, increased urinary incontinence, less sexual interest (men), and increased impotence and dyspareunia were observed. Cetuximab was associated with a deterioration of global health status during neoadjuvant chemotherapy but did not have any long-term detrimental effect. An improvement in bowel continence was observed after preoperative treatment and 3 years after sphincter-sparing surgery. Conclusions: Intensifying neoadjuvant treatment by administering induction systemic chemotherapy before chemoradiation therapy improves tumor-related symptoms and does not appear to have a significantly detrimental effect on QoL and BF, in both the short and the long term.« less

At the direction of the Food and Drug Administration, phenolphthalein was removed from all over-the-counter laxatives in 1999. Phenolphthalein was then replaced in most laxative products with the natural product senna from Cassia acutifolia Delile, which contains various anthraquinones. No data are available on the safety of senna use in children <6 years of age. To describe the clinical outcomes of exposure to unintentional ingestion of senna-containing laxatives in young children. All ingestion exposures of senna-containing laxatives in children <5 years of age from 6 poison centers over a 9-month period were evaluated. Inclusion criteria required 24-hour follow-up and the presence of diarrhea to confirm ingestion. Parents were told routinely that severe diaper rash was possible and to protect the perianal area with frequent cleansing and a barrier ointment if the child was wearing diapers. During the study period, 111 cases were reported: 19 children experienced no diarrhea, 4 were lost to follow-up, and 88 exposures were evaluated. Fifty-two children (59%) were

Retinoic acid has been shown to improve the aged-appearing skin. However, less is known about the anti-ageing effects of retinol (ROL, vitamin A), a precursor of retinoic acid, in aged human skin in vivo. This study aimed to investigate the molecular basis of ROL anti-ageing properties in naturally aged human skin in vivo. Sun-protected buttock skin (76 ± 6 years old, n = 12) was topically treated with 0.4% ROL and its vehicle for 7 days. The effects of topical ROL on skin epidermis and dermis were evaluated by immunohistochemistry, in situ hybridization, Northern analysis, real-time RT-PCR and Western analysis. Collagen fibrils nanoscale structure and surface topology were analysed by atomic force microscopy. Topical ROL shows remarkable anti-ageing effects through three major types of skin cells: epidermal keratinocytes, dermal endothelial cells and fibroblasts. Topical ROL significantly increased epidermal thickness by stimulating keratinocytes proliferation and upregulation of c-Jun transcription factor. In addition to epidermal changes, topical ROL significantly improved dermal extracellular matrix (ECM) microenvironment; increasing dermal vascularity by stimulating endothelial cells proliferation and ECM production (type I collagen, fibronectin and elastin) by activating dermal fibroblasts. Topical ROL also stimulates TGF-β/CTGF pathway, the major regulator of ECM homeostasis, and thus enriched the deposition of ECM in aged human skin in vivo. 0.4% topical ROL achieved similar results as seen with topical retinoic acid, the biologically active form of ROL, without causing noticeable signs of retinoid side effects. 0.4% topical ROL shows remarkable anti-ageing effects through improvement of the homeostasis of epidermis and dermis by stimulating the proliferation of keratinocytes and endothelial cells, and activating dermal fibroblasts. These data provide evidence that 0.4% topical ROL is a promising and safe treatment to improve the naturally aged human skin. © 2016 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Achievement of very deep knee flexion after total knee arthroplasty (TKA) can play a critical role in the satisfaction of patients who demand a floor-sitting lifestyle and engage in high-flexion daily activities (e.g., seiza-sitting). Seiza-sitting is characterized by the knees flexed >145º and feet turned sole upwards underneath the buttocks with the tibia internally rotated. The present study investigated factors affecting the achievement of seiza-sitting after TKA using posterior-stabilized total knee prosthesis with high-flex knee design. Subjects comprised 32 patients who underwent TKA with high-flex knee prosthesis and achieved seiza-sitting (knee flexion >145º) postoperatively. Another 32 patients served as controls who were capable of knee flexion >145º preoperatively, but failed to achieve seiza-sitting postoperatively. Accuracy of femoral and tibial component positions was assessed in terms of deviation from the ideal position using a two-dimensional to three-dimensional matching technique. Accuracies of the component position, posterior condylar offset ratio and intraoperative gap length were compared between the two groups. The proportion of patients with >3º internally rotated tibial component was significantly higher in patients who failed at seiza-sitting (41 %) than among patients who achieved it (13 %, p = 0.021). Comparison of intraoperative gap length between patient groups revealed that gap length at 135º flexion was significantly larger in patients who achieved seiza-sitting (4.2 ± 0.4 mm) than in patients who failed at it (2.7 ± 0.4 mm, p = 0.007). Conversely, no significant differences in gap inclination were seen between the groups. From the perspective of surgical factors, accurate implant positioning, particularly rotational alignment of the tibial component, and maintenance of a sufficient joint gap at 135º flexion appear to represent critical factors for achieving >145º of deep knee flexion after TKA.

The Compression Intensity Index: a practical anatomical estimate of the biomechanical risk for a deep tissue injury.

PubMed

Gefen, Amit

2008-01-01

Pressure-related deep tissue injury (DTI) is a severe form of pressure ulcer that initiates in compressed muscle tissues under bony prominences, and progresses superficially towards the skin. Patients with impaired motosensory capacities are at high risk of developing DTI. There is a critical medical need for developing risk assessment tools for DTI. A new anatomical index, the Compression Intensity Index: CII=(BW/Rt);[1/2], which depends on the body weight (BW), radius of curvature of the ischial tuberosities (R) and thickness of the underlying gluteus muscles (t), is suggested for approximating the loading intensity in muscle tissue during sitting in permanent wheelchair users, as part of a clinically-oriented risk assessment for DTI. Preliminary CII data were calculated for 6 healthy and 4 paraplegic subjects following MRI scans, and data were compared between the groups and with respect to a gold standard, being a previously developed subject-specific MRI-finite-element (MRI-FE) method of calculating muscle tissue stresses (Linder-Ganz et al., J. Biomech. 2007). Marked differences between the R and t parameters of the two groups caused the CII values of the paraplegics to be approximately 1.6-fold higher than for the healthy (p<0.001), thereby indicating on the sensitivity of this parameter to the pathoanatomical changes that occur in the buttocks with paraplegia. Data of CII correlated reasonably with the gold standard calculations of MRI-FE muscle stresses (correlation coefficient 0.65). Since CII measurements do not require highly-specialized biomechanical numerical analyses such as MRI-FE, CII has the potential to serve as a practical, quick, and cost-effective approximation of the loading intensity in muscles of wheelchair-bound or bedridden patients. Hence, CII measurements can be integrated into DTI-risk-assessment tools, the need of which is now being discussed intensively in the American and European Pressure Ulcer Advisory Panel meetings.

Delphi. The aim of this study was to obtain an expert consensus on which history factors are most important in the clinical diagnosis of lumbar spinal stenosis (LSS). LSS is a poorly defined clinical syndrome. Criteria for defining LSS are needed and should be informed by the experience of expert clinicians. Phase 1 (Delphi Items): 20 members of the International Taskforce on the Diagnosis and Management of LSS confirmed a list of 14 history items. An online survey was developed that permits specialists to express the logical order in which they consider the items, and the level of certainty ascertained from the questions. Phase 2 (Delphi Study) Round 1: Survey distributed to members of the International Society for the Study of the Lumbar Spine. Round 2: Meeting of 9 members of Taskforce where consensus was reached on a final list of 10 items. Round 3: Final survey was distributed internationally. Phase 3: Final Taskforce consensus meeting. A total of 279 clinicians from 29 different countries, with a mean of 19 (±SD: 12) years in practice participated. The six top items were "leg or buttock pain while walking," "flex forward to relieve symptoms," "feel relief when using a shopping cart or bicycle," "motor or sensory disturbance while walking," "normal and symmetric foot pulses," "lower extremity weakness," and "low back pain." Significant change in certainty ceased after six questions at 80% (P < .05). This is the first study to reach an international consensus on the clinical diagnosis of LSS, and suggests that within six questions clinicians are 80% certain of diagnosis. We propose a consensus-based set of "seven history items" that can act as a pragmatic criterion for defining LSS in both clinical and research settings, which in the long term may lead to more cost-effective treatment, improved health care utilization, and enhanced patient outcomes. 2.

Preservation of the Acetabular Cup During Revision Total Hip Arthroplasty Using a Novel Mini-navigation Tool: A Case Report.

While intraoperative navigation systems have been shown to improve outcomes in primary total hip arthroplasty (THA), their use in the context of revision has been largely overlooked. This case report presents the first documented use of an imageless navigation tool in the context of revision THA, and an unexpected benefit to the surgical procedure as a result. An 84-year-old female patient presented following five episodes of dislocation of the left hip and with pain in the left buttock, groin, and posterior aspect of her hip. Relevant surgical history included primary hip arthroplasty in 1999 and the first revision in 2014. Preoperative analysis revealed a constrained liner that had become disengaged and migrated inferiorly, lodging at the distal aspect of the femoral neck. Acetabular protrusion was also noted. The pre-operative plan included the replacement of the fragmented liner and likely of the acetabular cup due to hardware failure. Intraoperative assessment, however, revealed that the cup was in good condition and would be difficult to remove due to substantial bony ingrowth. With the assistance of imageless navigation, the orientation of the acetabular cup was determined and a new constrained liner was cemented into the preexisting acetabular component at an altered orientation, correcting anteversion by 7°. In revision hip arthroplasty cases, image-based navigation is limited by the presence of existing implants and corresponding metal artefact. This case demonstrates the successful use of an imageless navigation tool for revision surgery. Use of navigation led to the unexpected intraoperative discovery that the acetabular cup was in an acceptable state, and allowed the surgical team to correct the position of the cup using a constrained liner, thus preserving the cup. This significantly benefitted patient outcome, due to the risks associated with the removal of a firmly fixated acetabular cup. While more extensive research is required, this case demonstrates that imageless navigation may be an indispensable tool for revision surgery.

Background “Fitspiration” (also known as “fitspo”) aims to inspire individuals to exercise and be healthy, but emerging research indicates exposure can negatively impact female body image. Fitspiration is frequently accessed on social media; however, it is currently unclear the degree to which messages about body image and exercise differ by gender of the subject. Objective The aim of our study was to conduct a content analysis to identify the characteristics of fitspiration content posted across social media and whether this differs according to subject gender. Methods Content tagged with #fitspo across Instagram, Facebook, Twitter, and Tumblr was extracted over a composite 30-minute period. All posts were analyzed by 2 independent coders according to a codebook. Results Of the 415/476 (87.2%) relevant posts extracted, most posts were on Instagram (360/415, 86.8%). Most posts (308/415, 74.2%) related thematically to exercise, and 81/415 (19.6%) related thematically to food. In total, 151 (36.4%) posts depicted only female subjects and 114/415 (27.5%) depicted only male subjects. Female subjects were typically thin but toned; male subjects were often muscular or hypermuscular. Within the images, female subjects were significantly more likely to be aged under 25 years (P<.001) than the male subjects, to have their full body visible (P=.001), and to have their buttocks emphasized (P<.001). Male subjects were more likely to have their face visible in the post (P=.005) than the female subjects. Female subjects were more likely to be sexualized than the male subjects (P=.002). Conclusions Female #fitspo subjects typically adhered to the thin or athletic ideal, and male subjects typically adhered to the muscular ideal. Future research and interventional efforts should consider the potential objectifying messages in fitspiration, as it relates to both female and male body image. PMID:28356239

Can Ultrasound Accurately Assess Ischiofemoral Space Dimensions? A Validation Study.

Ischiofemoral impingement is a potential cause of hip and buttock pain. It is evaluated commonly with magnetic resonance imaging (MRI). To our knowledge, no study previously has evaluated the ability of ultrasound to measure the ischiofemoral space (IFS) dimensions reliably. To determine whether ultrasound could accurately measure the IFS dimensions when compared with the gold standard imaging modality of MRI. A methods comparison study. Sports medicine center within a tertiary-care institution. A total of 5 male and 5 female asymptomatic adult subjects (age mean = 29.2 years, range = 23-35 years; body mass index mean = 23.5, range = 19.5-26.6) were recruited to participate in the study. Subjects were secured in a prone position on a MRI table with their hips in a neutral position. Their IFS dimensions were then acquired in a randomized order using diagnostic ultrasound and MRI. The main outcome measurements were the IFS dimensions acquired with ultrasound and MRI. The mean IFS dimensions measured with ultrasound was 29.5 mm (standard deviation [SD] 4.99 mm, standard error mean 1.12 mm), whereas those obtained with MRI were 28.25 mm (SD 5.91 mm, standard error mean 1.32 mm). The mean difference between the ultrasound and MRI measurements was 1.25 mm, which was not statistically significant (SD 3.71 mm, standard error mean 3.71 mm, 95% confidence interval -0.49 mm to 2.98 mm, t 19 = 1.506, P = .15). The Bland-Altman analysis indicated that the 95% limits of agreement between the 2 measurement was -6.0 to 8.5 mm, indicating that there was no systematic bias between the ultrasound and MRI measurements. Our findings suggest that the IFS measurements obtained with ultrasound are very similar to those obtained with MRI. Therefore, when evaluating individuals with suspected ischiofemoral impingement, one could consider using ultrasound to measure their IFS dimensions. III.

2013-06-01

Painful vertebral body hemangiomas have been successfully treated with vertebroplasty and kyphoplasty. Sacral hemangiomas are uncommon and as such painful sacral hemangiomas are rare entities. We report what we believe is only the second successful treatment of a painful sacral hemangioma with CT-guided sacroplasty. A 56-year-old woman with a history of right-sided total hip arthroplasty and lipoma excision presented to her orthopedic surgeon with persistent right-sided low back pain which radiated into her buttock and right groin and hindered her ability to walk and perform her activities of daily living. MRIs of the thoracic spine, lumbar spine and pelvis showed numerous lesions with imaging characteristics consistent with multiple hemangiomas including a 2.2×2.1 cm lesion involving the right sacrum adjacent to the right S1 neural foramen. Conservative measures including rest, physical therapy, oral analgesics and right-sided sacroiliac joint steroid injection did not provide significant relief. Given her lack of improvement and the fact that her pain localized to the right sacrum, the patient underwent CT-guided sacroplasty for treatment of a painful right sacral hemangioma. Under CT fluoroscopic guidance, a 10 gauge introducer needle was advanced through the soft tissues of the back to the margin of the lesion. Biopsy was then performed and after appropriate preparation, cement was then introduced through the needle using a separate cement filler cannula. Appropriate filling of the right sacral hemangioma was visualized using intermittent CT fluoroscopy. After injection of approximately 2.5 cc of cement, it was felt that there was near complete filling of the right sacral hemangioma. With satisfactory achievement of cement filling, the procedure was terminated. Pathology from biopsy taken at the time of the procedure was consistent with hemangioma. Image-guided sacroplasty with well-defined endpoints is an effective, minimally invasive and safe procedure. Patients with painful sacral hemangiomas can be treated with this technique with no significant complications.

A systematic approach to systemic contact dermatitis and symmetric drug-related intertriginous and flexural exanthema (SDRIFE): a closer look at these conditions and an approach to intertriginous eruptions.

PubMed

Winnicki, Monika; Shear, Neil H

2011-06-01

Systemic contact dermatitis is a condition that occurs when an individual sensitized to a contact allergen is exposed to that same allergen or a cross-reacting molecule through a systemic route. Systemic exposure to allergens can include transcutaneous, transmucosal, oral, intravenous, intramuscular, and inhalational routes. Baboon syndrome is perhaps the most recognizable form of systemic contact dermatitis, presenting with diffuse, well demarcated erythema of the buttocks, upper inner thighs, and axillae. Other forms of systemic contact dermatitis include dermatitis at sites of previous exposure to the allergen such as at a previous site of dermatitis or at sites of previous positive patch tests, dyshidrotic hand eczema, flexural dermatitis, exanthematous rash, erythroderma, and vasculitis-like lesions. The most common causes of systemic contact dermatitis consist of three groups of allergens: (i) metals including mercury, nickel, and gold; (ii) medications including aminoglycoside antibacterials, corticosteroids, and aminophylline; and (iii) plants and herbal products including the Compositae and Anacardiaceae plant families and Balsam of Peru. Baboon syndrome caused by systemic medications without a known history of previous cutaneous sensitization in the patient has been termed drug-related baboon syndrome (DRBS) or symmetric drug-related intertriginous and flexural exanthema (SDRIFE). Criteria for SDRIFE include exposure to systemic drug at first or repeated dose, erythema of the gluteal/perianal area and/or V-shaped erythema of the inguinal area, involvement of at least one other intertriginous localization, symmetry of affected areas, and absence of systemic toxicity. The most common causes are aminopenicillins, β-lactam antibacterials, and certain chemotherapeutic agents, though the list of etiologic agents continues to grow. Baboon syndrome and SDRIFE should be strongly considered in a patient presenting with a symmetric intertriginous eruption involving multiple body folds. With the knowledge of the most frequent causes of these conditions, a detailed history and review of exposures will guide the clinician in the search for the most likely etiologic agent.

The effect of human-mattress interface's temperature on perceived thermal comfort.

PubMed

Califano, R; Naddeo, A; Vink, P

2017-01-01

In recent years, methods that allow for an objective evaluation of perceived comfort, in terms of postural, physiological, cognitive and environmental comfort, have received a great deal of attention from researchers. This paper focuses on one of the factors that influences physiological comfort perception: the temperature difference between users and the objects with which they interact. The first aim is to create a measuring system that does not affect the perceived comfort during the temperatures' acquisition. The main aim is to evaluate how the temperature at the human-mattress interface can affect the level of perceived comfort. A foam mattress has been used for testing in order to take into account the entire back part of the human body. The temperature at the interface was registered by fourteen 100 Ohm Platinum RTDs (Resistance Temperature Detectors) placed on the mattress under the trunk, the shoulders, the buttocks, the legs, the thighs, the arms and the forearms of the test subject. 29 subjects participated in a comfort test in a humidity controlled environment. The test protocol involved: dress-code, anthropometric-based positioning on mattress, environment temperature measuring and an acclimatization time before the test. At the end of each test, each of the test subject's thermal sensations and the level of comfort perception were evaluated using the ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) scale. The data analyses concerned, in the first instance, correlations between the temperature at the interface and comfort levels of the different parts of the body. Then the same analyses were performed independently of the body parts being considered. The results demonstrated that there was no strong correlation among the studied variables and that the total increase of temperature at interface is associated with a reduction in comfort.

2015-03-01

This communication reports on the Mycetoma Research Centre of the University of Khartoum, Sudan experience on 6,792 patients seen during the period 1991-2014.The patients were predominately young (64% under 30 years old) males (76%). The majority (68%) were from the Sudan mycetoma belt and 28% were students. Madurella mycetomatis eumycetoma was the most common type (70%). In 66% of the patients the duration of the disease was less than five years, and 81% gave a history of sinuses discharging mostly black grains (78%). History of trauma at the mycetoma site was reported in 20%. Local pain was reported in 27% of the patients, and only 12% had a family history of mycetoma. The study showed that 57% of the patients had previous surgical excisions and recurrence, and only 4% received previous medical treatment for mycetoma. Other concomitant medical diseases were reported in 4% of the patients. The foot (76%) and hand (8%) were the most commonly affected sites. Less frequently affected sites were the leg and knee (7%), thigh (2%), buttock (2%) and arm and forearm (1%). Rare sites included the chest wall, head and neck, back, abdominal wall, perineum, oral cavity, tongue and eye. Multiple sites mycetoma was recorded in 135 (2%) of cases. At presentation, 37% of patients had massive lesions, 79% had sinuses, 8% had local hyper-hydrosis at the mycetoma lesion, 11% had regional lymphadenopathy, while 6% had dilated tortuous veins proximal to the mycetoma lesions. The diagnosis of mycetoma was established by combined imaging techniques and cytological, histopathological, serological tests and grain culture. Patients with actinomycetoma received a combination of antimicrobial agents, while eumycetoma patients received antifungal agents combined with various surgical excisions. Surgical excisions in the form of wide local excision, debridement or amputation were done in 807 patients, and of them 248 patients (30.7%) had postoperative recurrence. Different types of amputations were done in 120 patients (1.7%).

Surgical treatment of middle cluneal nerve entrapment neuropathy: technical note.

OBJECTIVE The etiology of low-back pain (LBP) is heterogeneous and is unknown in some patients with chronic pain. Superior cluneal nerve entrapment has been proposed as a causative factor, and some patients suffer severe symptoms. The middle cluneal nerve (MCN) is also implicated in the elicitation of LBP, and its clinical course and etiology remain unclear. The authors report the preliminary outcomes of a less invasive microsurgical release procedure to address MCN entrapment (MCN-E). METHODS The authors enrolled 11 patients (13 sites) with intractable LBP judged to be due to MCN-E. The group included 3 men and 8 women ranging in age from 52 to 86 years. Microscopic MCN neurolysis was performed under local anesthesia with the patient in the prone position. Postoperatively, all patients were allowed to walk freely with no restrictions. The mean follow-up period was 10.5 months. LBP severity was evaluated on the numerical rating scale (NRS) and by the Japanese Orthopaedic Association (JOA) and the Roland-Morris Disability Questionnaire (RDQ) scores. RESULTS All patients suffered buttock pain, and 9 also had leg symptoms. The symptoms were aggravated by standing, lumbar flexion, rolling over, prolonged sitting, and especially by walking. The numbers of nerve branches addressed during MCN neurolysis were 1 in 9 patients, 2 in 1 patient, and 3 in 1 patient. One patient required reoperation due to insufficient decompression originally. There were no local or systemic complications during or after surgery. Postoperatively, the symptoms of all patients improved statistically significantly; the mean NRS score fell from 7.0 to 1.4, the mean RDQ from 10.8 to 1.4, and the mean JOA score rose from 13.7 to 23.6. CONCLUSIONS Less invasive MCN neurolysis performed under local anesthesia is useful for LBP caused by MCN-E. In patients with intractable LBP, MCN-E should be considered.

Background: The pathogenesis of fifth metatarsal stress fractures remains uncertain. Hypothesis: Physical characteristics and environmental factors, which have received limited attention in the literature thus far, might be involved in the development of fifth metatarsal stress fractures. Study Design: Case-control study; Level of evidence, 3. Methods: To test the study hypothesis, a medical examination and survey of the living environment of collegiate soccer players was conducted and correlated with the existence of fifth metatarsal stress fractures. The survey and measurements were conducted in 273 male athletes from the same college soccer team between 2005 and 2013. A medical examination comprising assessment of stature, body weight, body mass index, foot–arch height ratio, toe-grip strength, quadriceps angle, leg-heel angle, functional reach test, single-leg standing time with eyes closed, straight-leg raise angle, finger-floor distance, heel-buttock distance, ankle joint range of motion, and a general joint laxity test were performed once a year, along with a questionnaire survey. The survey was also repeated when a fifth metatarsal stress fracture was diagnosed. The study participants were separated into a fifth metatarsal stress fracture injury group and a noninjury group. The measurement items and survey items were compared, and the association between the factors and the presence or absence of injuries was analyzed. Results: Toe-grip strength was significantly weaker in the injury group compared with the noninjury group, suggesting that weak toe-grip is associated with fifth metatarsal stress fracture (P < .05). In addition, fifth metatarsal stress fractures were more common in the nondominant leg (P < .05). Between-group comparisons of the other items showed no statistically significant differences. Conclusion: The association between weak toe-grip strength and fifth metatarsal fracture suggests that weak toe-grip may lead to an increase in the load applied onto the lateral side of the foot, resulting in stress fracture. The finding of stress fracture being more common in the nondominant leg needs further study. PMID:26535399

Dogma has long prevailed regarding the ageing of bruises, and whether certain patterns of bruising are suggestive or diagnostic of child abuse. We conducted the first Systematic Reviews addressing these two issues, to determine the scientific basis for current clinical practice. There have been seven updates since 2004. An all language literature search was performed across 13 databases, 1951-2004, using >60 key words, supplemented by 'snowballing' techniques. Quality standards included a novel confirmation of abuse scale. Updates used expanded key words, and a higher standard for confirmation of abuse. Of 1495 potential studies, only three met the inclusion criteria for ageing of bruises in 2004, confirming that it is inaccurate to do so with the naked eye. This was roundly rejected when first reported, generating a wave of new studies attempting to determine a scientifically valid method to age bruises, none of which are applicable in children yet. Regarding patterns of bruising that may be suggestive or diagnostic of abuse, we included 23 of 167 studies reviewed in 2004, although only 2 were comparative studies. Included studies noted that unintentional bruises occur predominantly on the front of the body, over bony prominences and their presence is directly correlated to the child's level of independent mobility. Bruising patterns in abused children, differed in location (most common site being face, neck, ear, head, trunk, buttocks, arms), and tended to be larger. Updates have included a further 14 studies, including bruising in disabled children, defining distinguishing patterns in severely injured abused and non-abused children, and importance of petechiae. Systematic Reviews of bruising challenged accepted wisdom regarding ageing of bruises, which had no scientific basis; stimulated higher quality research on patterns of bruises distinguishing abusive and non-abusive bruising patterns, and highlighted the benefits of regular updates of these reviews.

The ischial region is the site most affected by pressure sores and has the highest recurrence and complication rates compared to other affected sites. We developed a practical and safe pedicled flap for reconstruction of ischial pressure sores based on the rich available perforators from the internal pudendal artery and the surplus of skin at the infragluteal fold. A retrospective cohort study was conducted in all patients who underwent ischial pressure ulcer reconstruction using the PIPAP flap between March 2010 and March 2017. The skin flap was designed along the gluteal fold. The skin perforators of the pudendal artery were marked with a Doppler probe in the medial region of the gluteal fold. Surgery was performed in the jackknife position, and flaps were elevated in the suprafascial plane. Patients were assessed for minor (requiring no additional surgery) and major complications (requiring additional surgery). Twenty-seven patients (34 flaps) were identified. The median follow-up period was 38 months (IQR 37). Primary closure of the donor-site was achieved in all procedures, only one flap required muscle flap transposition in order to fill the dead space. The mean operating time was 60 ± 21 minutes. In six flaps (9%) wound healing problems were noted that did not require an additional operative procedure. Among the nine flaps (27%) that required a second procedure, 3 (9%) were necessary due to recurrent ulcers. The PIPAP flap is a safe and reliable alternative for ischial pressure sore reconstruction, certainly when compared to available techniques. Moreover, it has significant advantages over other techniques including minimal donor-site morbidity, preservation of posterior thigh skin, buttock-line integrity and reliable vascularity.

To assess the association of genital numbness and erectile dysfunction in male cyclists. Cyclists were recruited through Facebook advertisements and outreach to sporting clubs. This is a secondary analysis of a larger epidemiological population-based study that examined sexual and urinary wellness in athletes. We queried cycling habits and erectile function using Sexual Health Inventory for Men (SHIM). A total of 2 774 male cyclists were included in the analysis. Amongst cyclists, there was a statistically significant increase in the trend of genital numbness presence with more years of cycling (P = 0.002), more frequent weekly cycling (P < 0.001), and longer cycling distance at each ride (P < 0.001). Less frequent use of padded shorts (odds ratio [OR] 0.14, P < 0.001) and lower handlebar (OR 0.49, P < 0.001) were associated with numbness, but body mass index (BMI) (OR 1.1, P = 0.33) and age (OR 1.2, P = 0.15) were not. In a multivariate logistic regression model, after adjusting for age, BMI, and lifetime miles (calculated by average daily cycling mileage × cycling days/week × cycling years.), there were no statistically significant differences in mean SHIM score between cyclists with and cyclists without numbness (20.3 vs 20.2, P = 0.83). However, interestingly, the subset of cyclists who reported numbness in the buttock reported statistically significantly worse SHIM scores (20.3 vs 18.4, P < 0.001). This association was not present in cyclists who reported numbness in the scrotum, penis, or perineum and remained significant after adjusting for overall biking intensity. Cyclists report genital numbness in proportion with biking intensity but numbness is not associated with worse sexual function in this cohort. © 2018 The Authors BJU International © 2018 BJU International Published by John Wiley & Sons Ltd.

Effect of a Patient-Repositioning Device in an Intensive Care Unit On Hospital-Acquired Pressure Injury Occurences and Cost: A Before-After Study.

PubMed

Edger, Melinda

The principal aim of this study was to determine the hospital-acquired pressure injury (HAPI) rate before and after introduction of a repositioning device, measure staff-perceived level of exertion with device use, and assess return on investment. 1 group, before-and-after study. The sample comprised 717 patients cared for in a 17-bed intensive care unit. The study setting was the neonatal intensive care unit at Bon Secours Maryview Medical Center located in the mid-Atlantic United States (Portsmouth, Virginia). A safe patient-handling intervention was implemented as part of a quality improvement initiative. The effect of this system was measured using several outcome measures: (1) HAPI occurrences on the sacral area and buttocks, (2) perceived effort of use by staff, and (3) cost analysis. We used the validated Borg Scale to measure perceived exertion that was ranked on a scale from 6 to 20, where higher scores indicate greater exertion. Cost comparisons were completed before and after introduction of the patient-repositioning system. Cost analysis was determined using internal dollar amounts calculated for each stage of pressure injury. The return on investment was calculated by comparing the cost of HAPIs and the product after the intervention with the costs of HAPIs before the intervention. Analysis revealed a statistically significant reduction in HAPI occurrence from 1.3% to 0% (P = .004) when baseline manual repositioning (standard of care) was compared with use of the repositioning system. Caregivers reported significantly less exertion when using the repositioning device as compared with standard of care repositioning (P < .001). The return on investment was estimated to be $16,911. Use of a repositioning device resulted in significantly reduced HAPIs. Perceived exertion for repositioning the patient with a repositioning device was significantly less than repositioning with standard of care. A cost analysis estimated a return on investment as a result of the intervention on HAPI prevention.

From early pubescence, both degree and distribution of fatness have been related to health risk factors. Measures that are capable of providing estimates of overall fatness and the extent of high risk fat patterning are, therefore, advantageous. The objective of this study was to compare estimates of body fatness and fat distribution using magnetic resonance imaging with the traditional methods of hydrostatic weighing, skinfolds, and anthropometry in 11-year-old boys and girls. Subjects were 25 boys and 25 girls, representative of their age cohort's body mass index (BMI) range. Total fat using MRI was obtained by summing subcutaneous and internal fat areas from four transaxial scans at the chest, waist, hips, and thigh. Mean MRI total fat (MRI FAT) was 357 (±152) cm 2 with a range of 172-739 cm 2 for boys and 427 (±174) cm 2 with a range of 209-995 for girls. Correlation analyses revealed strong relationships between MRI FAT and UWW FAT (r = 0.73 boys, r = 0.77 girls), and the sum of four skinfolds (r = 0.94 boys, r = 0.88 girls). Analysis of the MRI data alone revealed that MRI FAT variation is largely explained by subcutaneous fat deposition at the waist in boys and at the level of the buttocks in girls, with most skinfolds correlating highly with MRI FAT in both sexes. Results of stepwise multiple regression showed that an abdominal skinfold and thigh circumference explained 95% of MRI FAT in boys, and 86% of the variance in girls. These data show that magnetic resonance images can provide useful information for the identification of discriminating field measures of fatness and its distribution in 11-year-old children. © 1994 Wiley-Liss, Inc.

Dermatitis herpetiformis: a cutaneous manifestation of coeliac disease.

Dermatitis herpetiformis (DH) is an itchy blistering skin disease with predilection sites on elbows, knees, and buttocks. Diagnosis is confirmed by showing granular immunoglobulin A deposits in perilesional skin. DH is one manifestation of coeliac disease; the skin symptoms heal with gluten free diet (GFD) and relapse on gluten challenge. Of the first-degree relatives, 5% may be affected by either condition. Tissue transglutaminase (TG2) is the autoantigen in coeliac disease and epidermal transglutaminase (TG3) in DH. Both diseases conditions exhibit TG2-specific autoantibodies in serum and small bowel mucosa; patients with DH have IgA-TG3 in the skin. There are some divergencies between these two phenotypes. One-fourth of DH patients do not have small bowel mucosal villous atrophy, but virtually all have coeliac-type inflammatory changes. The skin symptoms respond slowly to GFD. The incidence of coeliac disease is increasing, whereas the opposite is true for DH. A female predominance is evident in coeliac disease, while DH may be more common in males. Coeliac disease carries the risk of small intestinal T-cell lymphoma; in DH B-cell lymphomas at any site may prevail. Adult coeliac disease carries a slightly increased elevated mortality risk, whereas in DH, the relative mortality rate is significantly decreased. Key messages Dermatitis herpetiformis is a cutaneous manifestation of coeliac disease; both conditions are genetically determined and gluten-dependent. Gastrointestinal symptoms and the degree of villous atrophy are less obvious in dermatitis herpetiformis than in coeliac disease. Both show tissue transglutaminase (TG2) specific autoantibodies in serum and small bowel mucosa. In addition, TG3-targeted IgA antibodies are found in the skin of DH patients Both conditions carry an increased elevated risk of lymphoma, in coeliac disease small intestinal T-cell lymphoma, in dermatitis herpetiformis mainly B-cell lymphoma at various sites. Coeliac disease is currently eight times more common that DH; the incidence of DH is decreasing in contrast to that of coeliac disease, where it is increasing.

High personal UVR doses can be gained during leisure activities, causing intense self-resolving inflammation (sunburn) of unprotected skin. UVR activates release of membrane fatty acids and upregulates their metabolism by cyclooxygenases (COX) and lipoxygenases (LOX) to different eicosanoids. While COX-derived prostaglandin (PG)E(2) is a potent mediator of sunburn vasodilatation, LOX-derived 15-hydroxyeicosatetraenoic acid (HETE) and its lipoxin metabolites may contribute to sunburn limitation. We explored the relationships between expression of these lipid mediators and the clinical and histological outcomes, comparing responses of individuals prone and more resistant to sunburn. An acute UVR exposure of 12 SED (standard erythema dose) was applied to buttock skin of 32 white Caucasians (n = 16 phototype I/II, n = 16 phototype III/IV), and over the subsequent 72 h assessments were made of skin erythema, immunohistochemical expression of leukocyte markers, COX-2, 12-LOX, 15-LOX and nitric oxide synthase (NOS), and eicosanoid levels by LC/ESI-MS/MS. Evidence of a significant inflammatory response was seen earlier in phototype I/II with regard to expression of erythema (4 h, p < 0.001), neutrophil infiltration (24 h, p = 0.01), epidermal COX-2 (24 h, p < 0.05) and 12-LOX (24 h, p < 0.01), and dermal eNOS (24 h, p < 0.05) proteins, although CD3+ lymphocyte infiltration showed an earlier increase in phototype III/IV (24 h, p < 0.05). Although erythema was equivalent at 72 h in both groups, phototype I/II showed higher PGE(2) accompanied by elevated 15-HETE, and a strong positive correlation was seen between these mediators (n = 18, r = 0.805, p = 0.0001). Hence anti-inflammatory eicosanoid 15-HETE may temper the pro-inflammatory milieu in sunburn, having greater influence in those prone to sunburn than those more resistant, given the same high UVR exposure conditions.

What's Tramadol Got to Do with It? A Case Report of Rebound Hypoglycemia, a Reappraisal and Review of Potential Mechanisms.

PubMed

Tramadol has gained traction as an analgesic of choice among pain practicing physicians. However some concerns regarding a previously unlabeled adverse reaction - hypoglycemia - have cast it in a dim light. Prior reports have noted an associated risk of hospitalization for hypoglycemia after tramadol use, but whether tramadol is the main causal agent is poorly understood and the underlying mechanisms are not well delineated. We present a unique case of rebound hypoglycemia as a variation of the theme of tramadol's adverse effect profile in a patient with type 1 diabetes mellitus, and reappraise potential mechanisms underlying this underappreciated phenomenon. A 71-year-old woman presented with right buttock pain and right lateral leg discomfort of 9-month duration. Her physical exam suggested sacroiliac joint (SIJ) etiology, confirmed by magnetic resonance imaging (MRI). She was scheduled for an SIJ-diagnostic and therapeutic block and started on tramadol 50 mg 3 times daily on as needed basis. The patient subsequently developed severe hypoglycemia initially resistant to euglycemia restorative interventions with a rebound episode. Hypoglycemia resolved with oral ingestion of high levels of glucose and the patient was taken off tramadol. Fortunately, she did not require hospitalization. The clinical scenario described is a case of rebound hypoglycemia after tramadol use in a patient with type-1 diabetes naïve to opioid analgesics. The episodes of hypoglycemia aligned perfectly with the anticipated pharmacodynamic and pharmacokinetic properties of tramadol. The specificity and temporality of events after tramadol use in this patient fulfilled causality criteria. Tramadol may cause rebound hypoglycemia in patients via interference of the intrinsic euglycemia-restoration pathways and a blunted autonomic counter-regulatory response to antecedent hypoglycemia. Its use must be tempered by this underappreciated adverse effect profile.Key words: Tramadol, hypoglycemia, sacroiliac joint arthritis, type 1 diabetes mellitus, serotonin uptake inhibitors, glutamate receptor 4.

"Fitspiration" (also known as "fitspo") aims to inspire individuals to exercise and be healthy, but emerging research indicates exposure can negatively impact female body image. Fitspiration is frequently accessed on social media; however, it is currently unclear the degree to which messages about body image and exercise differ by gender of the subject. The aim of our study was to conduct a content analysis to identify the characteristics of fitspiration content posted across social media and whether this differs according to subject gender. Content tagged with #fitspo across Instagram, Facebook, Twitter, and Tumblr was extracted over a composite 30-minute period. All posts were analyzed by 2 independent coders according to a codebook. Of the 415/476 (87.2%) relevant posts extracted, most posts were on Instagram (360/415, 86.8%). Most posts (308/415, 74.2%) related thematically to exercise, and 81/415 (19.6%) related thematically to food. In total, 151 (36.4%) posts depicted only female subjects and 114/415 (27.5%) depicted only male subjects. Female subjects were typically thin but toned; male subjects were often muscular or hypermuscular. Within the images, female subjects were significantly more likely to be aged under 25 years (P<.001) than the male subjects, to have their full body visible (P=.001), and to have their buttocks emphasized (P<.001). Male subjects were more likely to have their face visible in the post (P=.005) than the female subjects. Female subjects were more likely to be sexualized than the male subjects (P=.002). Female #fitspo subjects typically adhered to the thin or athletic ideal, and male subjects typically adhered to the muscular ideal. Future research and interventional efforts should consider the potential objectifying messages in fitspiration, as it relates to both female and male body image. ©Elise Rose Carrotte, Ivanka Prichard, Megan Su Cheng Lim.

Disc herniation is one of the most common causes of low back pain with radicular pain. Among various types of disc herniation, the extraforaminal disc herniation is a rare cause of lumbar radiculopathy. The aim of presenting this case study is to demonstrate the benefits of Chiropractic care including spine and extremity manipulation and rehabilitation in the treatment of a rare case of extraforaminal L4 nerve entrapment causing severe L4 radiculopathy and chronic mild low back pain (LBP). The aim of presenting this case study is to demonstrate the benefits of Chiropractic care including spine and extremity manipulation and rehabilitation in treatment of rare case of extraforaminal L4 nerve entrapment which caused severe L4 radiculopathy and chronic mild low back pain (LBP). A 45-year old female patient arrived at the clinic with chronic mild low back pain and right buttock pain, all of which had presented for two years' duration. During the preceding month, the radicular pain initiated in medium to high intensity, radiating to her right leg following the L4 dermatomal pattern with a periodic tingling sensation in her right foot. A neuro exam demonstrated a proprioception deficit in her right leg. A Romberg test was positive. The patient was treated by low amplitude high velocity spinal and extremity manipulation for 10 consecutive sessions (2 weeks), followed by rehabilitation and exercise therapy including advanced myofascial release therapy for an additional 12 sessions (4 weeks). After treatment, the patient reported a significant improvement in her low back pain and radiculopathy. In addition, she achieved some improvement in balance. It seems that Chiropractic care and rehabilitation therapy may be a safe and effective modality in treatment of an L4 radiculopathy in a patient with an extraforaminal L4 nerve entrapment. Although it is rare, an L4 extraforaminal disc herniation should be considered as a possible cause of symptoms in patients with chronic mild low back pain and severe L4 radiculopathy.

One of the oldest crimes in human civilization is homicide which started from murder of Abel by the hands of Cane. With the passage of time manner of homicide have been changing. Study of pattern of homicide in any civil society is the first step towards development of intervention to reduce the impact of homicidal crimes. This study was conducted at the department of forensic medicine and toxicology Gomal Medical College DI Khan to know the pattern of the homicides, taking it as the first step in the prevention of crime. The present study was conducted over two years 2007-08. The data collected includes all reported unnatural deaths from the urban and rural areas of district on which autopsies were conducted in the district headquarter teaching hospital DI Khan and department of Forensic Medicine and Toxicology, Gomal Medical College DL Khan. Homicidal deaths constituted 259/341 (76%) of all autopsies. Out of these homicides 59.07% were caused by the firearm. The most common firearm weapons were high velocity rifled weapons (AK-47, rifles and pistols). A total of 304 injuries were found in various body regions giving an average of about two injuries per victim/person. The head, neck and face sustained the highest numbers of injuries 100, (32.90%) followed by chest 91 (29.93%) and abdomen 47 (15.4%); the extremities, buttock and genitalia together sustained 65 (21.38 %) injuries. A part from firearm injuries unfortunately in our this study the second highest cause of homicidal deaths was bomb blasts injuries either due to suicide bombers or remote control bombs. The numbers of deaths due to blast injuries were 82 for the year 2007/08 out of total homicidal deaths and percentage was 32.66%. The vast majority of homicidal deaths in this area are caused by firearms like other big cities of the province like Peshawar, which bring up issues related to possession of firearms and change in cultural attitude towards the use of firearm, if a decrease in firearm related homicides is desired.

Background Extracorporeal shock wave therapy has been successfully introduced for the treatment of cellulite in recent years. However, it is still unknown whether the individual clinical outcome of cellulite treatment with extracorporeal shock wave therapy can be predicted by the patient’s individual cellulite grade at baseline, individual patient age, body mass index (BMI), weight, and/or height. Methods Fourteen Caucasian females with cellulite were enrolled in a prospective, single-center, randomized, open-label Phase II study. The mean (± standard error of the mean) cellulite grade at baseline was 2.5±0.09 and mean BMI was 22.8±1.17. All patients were treated with radial extracorporeal shock waves using the Swiss DolorClast® device (Electro Medical Systems, S.A., Nyon, Switzerland). Patients were treated unilaterally with 2 weekly treatments for 4 weeks on a randomly selected side (left or right), totaling eight treatments on the selected side. Treatment was performed at 3.5–4.0 bar, with 15,000 impulses per session applied at 15 Hz. Impulses were homogeneously distributed over the posterior thigh and buttock area (resulting in 7,500 impulses per area). Treatment success was evaluated after the last treatment and 4 weeks later by clinical examination, photographic documentation, contact thermography, and patient satisfaction questionnaires. Results The mean cellulite grade improved from 2.5±0.09 at baseline to 1.57±0.18 after the last treatment (ie, mean δ-1 was 0.93 cellulite grades) and 1.68±0.16 at follow-up (ie, mean δ-2 was 0.82 cellulite grades). Compared with baseline, no patient’s condition worsened, the treatment was well tolerated, and no unwanted side effects were observed. No statistically significant (ie, P<0.05) correlation was found between individual values for δ-1 and δ-2 and cellulite grade at baseline, BMI, weight, height, or age. Conclusion Radial shock wave therapy is a safe and effective treatment option for cellulite. The individual clinical outcome cannot be predicted by the patient’s individual cellulite grade at baseline, BMI, weight, height, or age. PMID:24920933

Acoustic Wave Treatment For Cellulite—A New Approach

Russe-Wilflingseder, Katharina; Russe, Elisabeth

2010-05-01

Background and Objectives: Cellulite is a biological caused modification of the female connective tissue. In extracorporeal shockwave therapy (ESWT) pulses are penetrating into the tissue without causing a thermal effect or micro lesions, but leading to a stimulation of tissue metabolism and blood circulation, inducing a natural repair process with cell activation and stem cells proliferation. Recently ESWT treatment showed evidence of remodelling collagen within the dermis and of stimulating microcirculation in fatty tissue. Study Design and Methods: The study was designed to assess acoustic wave treatment for cellulite by comparison treated vs. untreated side (upper-leg and buttock). Each individual served as its own control. 11 females with a BMI less then 30 and an age over 18 years were included. 6 treatments were given weekly with radial acoustic waves. Documentation was done before and 1, 4, 12 weeks after last treatment by standardized photo documentation, relaxed and with muscle contraction, measurement of body weight and circumference of the thigh, pinch test, and evaluation of hormonal status and lifestyle. The efficacy of AWT/EPAT was evaluated before and 1, 4, 12 weeks after last treatment. Patients rated the improvement of cellulite, overall satisfaction and acceptance. The therapist assessed improvement of cellulite, side effects and photo documentation treated vs. untreated side, before vs. after treatment. The blinded investigator evaluated the results using photo documentation right vs. left leg, before vs. after treatment in a frontal, lateral and dorsal view, relaxed and with muscle contraction. Results: The improvement of cellulite at the treated side was rated by patients with 27,3% at week 4 and 12, by the therapist with 34,1% at week 4 and 31,2% at week 12 after the last treatment The blinded investigator could verify an improvement of cellulite in an increasing number of patients with increasing time interval after treatment. No side effects were seen. Conclusion: Radial acoustic waves are effective and safe to treat cellulite. The effect of treatment begins delayed and is first seen after 5 treatments. The improvement of cellulite increases continual up to 3 months. Patients' satisfaction and acceptance is high

Introduction: Low back pain is characterized by a range of symptoms which include pain, muscle tension or stiffness, and is localized between the shoulder blades and the folds of the buttocks, with or without spreading to the legs. Non-Steroidal Anti Inflammatory Drugs (NSAIDs) are the drugs of choice which provide an analgesic effect for acute low back pain. Aim: To study the factors affecting low back pain, efficacy and safety of different non-steroidal anti-inflammatory drugs (aceclofenac, diclofenac, naproxen and nimesulide) in low back pain. Methodology: Data collection form and numeric pain rating scale were used as study tools for studying patients’ demographies and severities of pain respectively. Patients prescribed with aceclofenac 100 mg , diclofenac 100 mg, naproxen 500 mg and nimesulide 100 mg for acute low back pain at Orthopaedics Outpatients Department of Manipal Teaching Hospital, Nepal, were enrolled in this study. The decrease in pain scores was recorded on 5th and 10th days of follow-up and pain scores were calculated. Descriptive statistics and Kruskal Wallis non parametric test were used for analysis. Results: Among 150 patients, 67.3% were females (n=101). Low back pain was more prevalent (24.7%) in age-group of 59-68 years and a positive correlation was seen. Similarly, low back pain was found to be high among people involved in agriculture, heavy weight lifters and non smokers. The decrease in average pain scores was more in the patients treated with aceclofenac (4.83 ± 0.537), followed by that in those who were treated with naproxen (4.13 ± 0.067) and diclofenac (3.84 ± 0.086). The decrease in pain scores was found to be lowest among patients who were treated with nimesulide (2.11 ± 0.148). Nimesulide presented more number of side-effects than the comparative drugs. Conclusion: Different factors affect low back pain, such as age, gender, personal habit, posture, occupation, weight lifting. Aceclofenac showed greater decrease in pain scores with lesser number of side-effects. PMID:24551630

In Indonesia, National Standardization Agency of Indonesia issued the Indonesian National Standard SNI 12-1015-1989 and SNI 12-1016-1989 to define the type of furniture dimensions that should be used by children in the elementary school level. This study aims to examine whether the current national standards for elementary school furniture dimensions issued by National Standardization Agency of Indonesia match the up-to-date Indonesian children's anthropometry. Two types of school furniture, small type (Type I, for grade 1-3) and large type (Type II, for grade 4-6), were evaluated in terms of seat height, seat depth, seat width and backrest height of a chair as well as the height and underneath height of a desk. 1146 students aged between 6 and 12 years old participated in the study. Seven anthropometric measurements were taken including stature, sitting shoulder height, sitting elbow height, popliteal height, buttock-popliteal length, knee height and hip breadth. Based on the standard school furniture dimensions and students' body dimensions, numbers of matches and mismatches between them were computed. Results indicated a substantial degree of mismatch between children's anthropometry and the standard dimensions of school furniture. The standard seat height was not appropriate for students among different grades with the mismatch percentage ranging from 63.4% to 96.7% for Type I and 72.7% to 99.0% for Type II. For desk height, the standard dimensions were not appropriate for students among different grades with the mismatch percentage ranging from 32.3% to 88.9% for Type I and 67.7% to 99.0% for Type II. Apparently, the current standards are out of date and need to be updated. Four different sizes of school furniture were hence proposed to accommodate the variation in students' anthropometry from Grade 1 to Grade 6. The proposed standard dimensions (PrS) of school furniture cover a slightly broader range of age and present a higher cumulative fit than the current standard dimensions (CrS). In addition, a better strategy for sizing can be also developed to fit chairs and desks to a larger number of students. Copyright © 2017 Elsevier Ltd. All rights reserved.

To compare the therapeutic effects of acupuncture combined with fire dragon moxibustion and simple acupuncture therapy in the treatment of patients with cervical spondylotic radiculopathy (CSR) of kidney-deficiency-cold type. Ninety kidney-deficiency-cold type CSR outpatients were randomly divided into control (acupuncture, n =40) and treatment (acupuncture +moxibustion, n =50) groups. Acupuncture stimulation was applied to Dazhui (GV 14), Ganshu (BL 18), Tianzhu (BL 10) and Houxi (SI 3), Jiaji (EX-B 2), Taixi (KI 3), Shenmai (BL 62), Zusanli (ST 36), Shenshu (BL 23), etc once daily, 5 times a week, and two weeks altogether, except the weekend. In addition, for patients of the treatment group, herbal medicinal powder separated-fire dargon moxibustion was applied to the patient's back from GV14 and Fengmen (BL 12) on the top to Zhibian (BL 54) area at the buttock, once every 3 days, 5 times altogether. The therapeutic effect was evaluated according to "CSR-20-points scale" including 3 aspects as neck-shoulder pain, upper-limb pain-numbness, finger numbness; working and daily life ability and physical conditions (Spurling tests, sensory, myodynamia and tendon reflex). ① After the treatment, CSR-20-points scores in both treatment and control groups were significantly increased in comparison with pre-treatment in each group ( P <0.05), with the score being markedly higher in the treatment group than in the control group ( P <0.05). ② Of the 40 and 50 cases in the control and the treatment group, 2 and 13 were cured, 14 and 24 experienced a remarkable improvement, 12 and 11 were effective, and 12 and 2 failed, with the total effective rates being 70.0%(28/40) and 96.0%(48/50), respectively. The therapeutic effect of the treatment group was notably better than that of the control group ( P <0.05). Acupuncture combined with fire dragon moxibustion is superior to simple acupuncture therapy in improving clinical symptoms of patients with CSR of kidney-deficiency-cold type, being a recommendable scheme in clinical practice.

Minimally invasive sacroiliac joint fusion (SIJF) has become an increasingly accepted surgical option for chronic sacroiliac (SI) joint dysfunction, a prevalent cause of unremitting low back/buttock pain. The objective of this study was to report clinical and functional outcomes of SIJF using triangular titanium implants (TTI) in the treatment of chronic SI joint dysfunction due to degenerative sacroiliitis or sacroiliac joint (SIJ) disruption at 3 years postoperatively. A total of 103 subjects with SIJ dysfunction at 12 centers were treated with TTI in two prospective clinical trials (NCT01640353 and NCT01681004) and enrolled in this long-term follow-up study (NCT02270203). Subjects were evaluated in study clinics at study start and again at 3, 4, and 5 years. Mean (SD) preoperative SIJ pain score was 81.5, and mean preoperative Oswestry Disability Index (ODI) was 56.3. At 3 years, mean pain SIJ pain score decreased to 26.2 (a 55-point improvement from baseline, p <0.0001). At 3 years, mean ODI was 28.2 (a 28-point improvement from baseline, p <0.0001). In all, 82% of subjects were very satisfied with the procedure at 3 years. EuroQol-5D (EQ-5D) time trade-off index improved by 0.30 points ( p <0.0001). No adverse events definitely related to the study device or procedure were reported; one subject underwent revision surgery at year 3.7. SIJ pain contralateral to the originally treated side occurred in 15 subjects of whom four underwent contralateral SIJF. The proportion of subjects who were employed outside the home full- or part-time at 3 years decreased somewhat from baseline ( p =0.1814), and the proportion of subjects who would have the procedure again was lower at 3 years compared to earlier time points. In long-term (3-year) follow-up, minimally invasive trans-iliac SIJF with TTI was associated with improved pain, disability, and quality of life with relatively high satisfaction rates. Level II.

Major weight loss causes body deformities. Lower circumferential dermolipectomy with autologous gluteal augmentation by a fat island flap can restore a part of the body contour, but this procedure is associated with a high incidence of complications. The aim of this study was to analyse the benefit/risk ratio and the patients' satisfaction. All patients who underwent this procedure at the Nancy University Hospital over a 3-year period (between January 2010 and 2013) were reviewed; the complications were analysed and the patients' satisfaction rated. A total of 55 patients were included with a mean age of 41.0 years. The average body mass index of the patients was 28.2 kg/m² with a mean weight of 76.8 kg at the time of the procedure and a mean weight reduction of 49.6 kg. The mean operative time was 4.85 h. The average hospital stay was 6.1 days. The average haemoglobin loss was 3.0 g/dl, and 12 (21.8%) patients required a blood transfusion. Of the total number of patients, 22 (40%) developed at least one complication, including six (10.9%) major complications. Fifty-two patients answered the questionnaire; 49 (94.2%) patients would go through this procedure again. The overall satisfaction was rated as excellent by 29 (55.8%) patients and as pleasing by 22 (42.3%). The outcome was judged as excellent or pleasing for the abdomen by 29 (55.8%) and 20 (38.35%) patients, respectively, and for the buttocks by 17 (32.7%) and 29 (55.8%) patients, respectively. The quality of life was rated better after than before the intervention by 49 (94.2%) patients. Despite a high complication rate, the majority of patients confirmed that they would opt for this procedure again, showing an improvement in their quality of life with an aesthetic and functional benefit.

Background There is now good evidence about the management options for pregnant women with a breech presentation (buttocks or feet rather than head-first) at term; external cephalic version (ECV) – the turning of a breech baby to a head-down position and/or planned caesarean section (CS). Each of these options has benefits and risks and the relative importance of these vary for each woman, subject to her personal values and preferences, a situation where a decision aid may be helpful. Decision aids are designed to assist patients and their doctors in making informed decisions using information that is unbiased and based on high quality research evidence. Decision aids are non-directive in the sense that they do not aim to steer the user towards any one option, but rather to support decision making which is informed and consistent with personal values. The ECV decision aid was developed using the Ottawa Decision Support Framework, including a systematic review of the evidence about the benefits and risks of the options for breech pregnancy. It comprises an audiotape with a supplementary booklet and worksheet, a format that can be taken home and discussed with a partner. This project aims to evaluate the ECV decision aid for women with a breech presenting baby in late pregnancy. Study design We aim to evaluate the effectiveness of the decision aid compared with usual care in a randomised controlled trial in maternity hospitals that offer ECV. The study group will receive the decision aid in addition to usual care and the control group will receive standard information on management options for breech presentation from their usual pregnancy care provider. Approximately 184 women with a single breech-presenting baby at greater than 34 weeks gestation and who are clinically eligible for ECV will be recruited for the trial. The primary outcomes of the study are knowledge, decisional conflict, anxiety and satisfaction with decision-making that will be assessed using self-administered questionnaires. The decision aid is not intended to influence either the uptake of either ECV or planned CS, however we will monitor health service utilisation rates and maternal and perinatal outcomes.

To probe into the physical changes on the head and face of Chinese adults, find the representative indexes and provide references for head-face products design especially in the field of labor protection. The ISO7250-1996 and GB/T5703-99 Basic Human Body Measurements for Technological Design was used. Twenty items of head-face referential parameters and 4 items of body indexes (height, weight, waist circumference and buttock circumference) were measured by using sliding caliper, spreading caliper and pupillometer. The populations were sampled by age, gender and region and their influences on the head and face dimensions were statistically analyzed. By studying the relationship between these parameters with correlation and cluster analysis, the representative indexes of head and face dimensions were concluded. 3000 objectives (2026 men and 974 women) were involved in this survey. The results enunciated that the values of the items in male were larger than those in female. For example, the mean values of face length, face width, jaw width, lip length and nose protrusion were 117.0, 147.6, 118.5, 51.7, 18.7 mm for male and 109.7, 140.1, 114.5, 49.3, 17.7 mm for female. The regional disparity and obesity were significant factors. The sizes of head and face of north-eastern population were significantly bigger than those of south-western population except of maximum length of head, the length of lip and face configuration length. The sizes of head and face of obesity population were significantly bigger than those of non-obesity population (P < 0.01). By the cluster analysis, five representative indexes (face length, face width, jaw width, lip length and nose protrusion) were obtained. Further correction analysis suggested that these indexes could well represent the head-face dimensions. The influence of gender, region and obesity on the head-face dimensions is significant. The age is not a significant influential factor. Five representative indexes (face length, face width, jaw width, lip length and nose protrusion) are obtained to provide foundation in the standard design of head-face products.

Obesity is a worldwide health problem which is associated with a lot of complications. One of these comorbidities is the metabolic syndrome that is in correlation with abdominal fat thickness and waist circumference. Various methods were used to reduce abdominal fat thickness such as liposuction. A noninvasive method is the topical agent. In this study, we investigated the effectiveness of Arnebia euchroma (AE) ointment on the abdominal fat thickness. This study was a double-blind clinical trial which was done at the endocrinology clinic in Khorshid Hospital, Isfahan, Iran, in 2014. After explaining the procedure and obtaining informed consent, the candidates were randomly divided into the case and control groups. The participants of the case and control groups applied AE ointment or placebo for 6 weeks on their abdominal area. Body mass index, waist and buttock circumference, and abdominal fat thickness were measured in both case and control groups at their first visit and then at the next 2, 4, and 6 weeks. We used t -test for comparing parametric variables between groups, paired t -test for changes from baseline to final, and repeated measure ANOVA for changes at different steps. Sixty female candidates participated in this study (thirty in each group). Ten patients left the study and fifty participants finished the trial. At the end of the study, participants had a significant weight loss (2.96 ± 1.6 kg, P < 0.001) that was slightly more in the case group (3.15 ± 1.5 kg vs. 2.75 ± 1.7, P = 0.375). Abdominal circumference also decreased significantly in the participants (11.3 ± 6.7 cm, P < 0.001), but the changes were more significant in the case group (13.9 vs. 6.5 cm, P = 0.004). Similarly, abdominal fat thickness decreased significantly in the participants (2.3 ± 1.1 cm, P < 0.001), although changes were not significantly different between two groups (2.53 vs. 2.04 cm, P = 0.139). Topical AE ointment can reduce the abdominal fat thickness as well as the waist circumference without causing any side effect.

Study Design Mathematical model, combined with and verified using human subject data. Objective (1) To develop and verify a lumped-parameter mathematical model for prediction of spine forces during backward falls; (2) to use this model to evaluate the effect of floor stiffness on spine forces during falls; and (3) to compare predicted impact forces with forces previously measured to fracture the spine. Summary of Background Data Vertebral fractures are the most common osteoporotic fractures and commonly result from falls from standing height. Compliant flooring reduces the force at the ground during a backward fall from standing; however, the effect on spine forces is unknown. Methods A 6-df model of the body was developed and verified using data from 10 human subjects falling from standing onto 3 types of compliant floors (soft: 59 kN/m, medium: 67 kN/m, and firm: 95 kN/m). The simulated ground forces were compared with those measured experimentally. The model was also used to assess the effect of floor stiffness on spine forces at various intervertebral levels. Results There was less than 14% difference between model predictions and experimentally measured peak ground reaction forces, when averaged over all floor conditions. When compared with the rigid floor, average peak spine force attenuations of 46%, 43%, and 41% were achieved with the soft, medium, and firm floors, respectively (3.7, 3.9, 4.1 kN vs. 6.9 kN at L4/L5). Spine forces were lower than those at the ground and decreased cranially (4.9, 3.9, 3.7, 3.5 kN at the ground, L5/S1, L4/L5, and L3/L4, respectively, for the soft floor). Conclusion Lowering the floor stiffness (from 400 to 59 kN/m) can attenuate peak lumbosacral spine forces in a backward fall onto the buttocks from standing by 46% (average peak from 6.9 to 3.7 kN at L4/L5) to values closer to the average tolerance of the spine to fracture (3.4 kN).

Herpes simplex virus (HSV) lesions are prone to reactivation and recurrence in response to various local or systemic triggering factors. To study the characteristics of five bedridden geriatric patients who presented with herpetic recurrences on the buttocks, gluteal cleft, and perianal region during hospitalization. Data were gathered regarding age, gender, reason for hospitalization, localization of lesions, clinical presentation, previous clinical diagnosis and topical treatments, immune status and immunosuppressant drug intake, as well as prior history of labial or genital herpes. A skin biopsy was taken for histologic examination and immunohistochemical viral identification. Viral culture and viral serology were performed and data regarding antiviral therapy were recorded. The five patients (three women, two men) were aged >80 years and hospitalized for either severe drug-induced renal insufficiency (one case), severe pneumonia (two cases), or stroke causing restricted mobility (two cases). Numerous well demarcated, painful ulcerations developed in the perianal region of these patients, and one patient also presented with some vesicular lesions. The lesions had been confused with mycotic and/or bacterial infections for 10-14 days. No inguinal lymphadenopathies were present and there was no fever. None of the patients had a previous history of recurrent labial or genital HSV infections or HIV infection. Histology was suggestive of HSV infection in two of five patients. Immunohistochemistry identified HSV type I (three patients) and HSV type II (two patients) infections. Viral culture with immunofluorescence viral identification revealed HSV type I in one of the four patients in whom a swab for viral culture was taken. Serology revealed past HSV infection. All lesions cured gradually after 10-14 days of intravenous acyclovir (aciclovir) treatment. Herpetic lesions of the perineal region represent a rare complication in bedridden geriatric patients in the absence of a previous history of HSV infections at the same site. Common traits of patients with this condition were the presence of numerous ulcerated lesions, prolonged time course, and confinement to bed. The latter probably modifies the skin condition, which triggers viral reactivation and favors cutaneous extension of the infection. Complementary diagnostic methods for viral detection and identification are mandatory.

Retrospective observational cohort study. To describe outcomes, risk factors for complications, and relapse rates associated with the multimodal treatment approach for deep pressure ulcers (PUs) grade IV for the ischium, trochanter major, and sacral regions of patients with traumatic and non-traumatic spinal cord injury (SCI). The settings comprised two spinal cord units within a maximum care hospital. The treatment of all patients followed the modified interdisciplinary "Basler treatment concept". We included all individuals with SCI with a first occurrence of PU grade IV in the buttocks area between August 2008 and December 2012 inclusive, with a maximum follow-up of 3 years. Descriptive, univariate, and bivariate analyses were undertaken, as were group comparisons. In 47 patients aged 18-87 years (mean age: 51 years) a total of 63 fasciocutaneous and myocutaneous flaps were performed. Wound healing was complete after a mean of 34 days (SD = 21). Postoperative mobilisation in a wheelchair was performed after a mean of 46 days (SD = 24). Delayed healing was reported in 18 patients (38%), and revision surgery was necessary in five patients (11%). ASIA impairment scale (AIS) A (p = .001), and male gender (p = .001) were identified as risk factors for delayed wound healing and prolonged inpatient stay. Treatment-associated pneumonia occurred in four cases (11% of all patients, 25% of patients with tetraplegia). Patients were discharged when the time spent sitting in a wheelchair was 2 × 2 h per day; this occurred after a mean of 100 days (SD = 36). PU recurrence was observed in six cases (18%). Our multimodal treatment concept was found to have complication rates comparable to those in the literature; additionally, this approach might be associated with lower recurrence rates with respect to the literature. To reduce high rates of pneumonia occurrence among patients with tetraplegia, preventive measures need to be established. Further evidence of the efficiency of this complex treatment approach for PU in individuals with SCI is needed.

Sri Lanka is a resource-poor country in the South-East Asian region with good health indices. Ergonomics of children in educational environments is still novel in the region. An exploration into such issues and dissemination of the scientific evidence will stimulate policy makers in both education and health sector. An important ergonomic issue of the classroom is the seating arrangement. Essential aspects of seating include location of the chair and desk in relation to the blackboard and features of the chair and desk. Musculoskeletal pain is considered to be the most important negative effect due to mismatched ergonomics. A school-based descriptive cross sectional study was carried out in a district of Sri Lanka to ascertain the distribution of selected ergonomic factors related to seating arrangements in the classroom of school-going early adolescents and to assess their relationship to musculoskeletal pain. A sample of 1607 school children of Grade 6,7 and 8 were selected using stratified multi-stage cluster sampling method. There were 52.1% (N=838) females and 47.9% (N=769) males. Many ergonomic aspects related to classroom seating arrangements are not conducive for children. Children were seated with a mean distance of 398.04 cm (SD=132.09) to the blackboard. Nearly 23% of children had to turn more than 45~degrees to see the blackboard. A prevalence of > 80% mismatch was found between body dimensions of children and measurements of furniture. Musculoskeletal pain may have resulted from efforts to maintain stability while seated in incompatible furniture. Nearly 36% children complained of recurrent musculoskeletal pain. Musculoskeletal pain may have resulted from efforts to maintain stability while seated in incompatible furniture. Mismatched seat depth - buttock-popliteal length posed 1.59 times risk recurrent musculoskeletal pain. Despite, children perceived a good chair comfort. Use of backrest lowered the risk of recurrent pain. Results shows that programme planners can utilize such evidence to provide simple ergonomic solutions at national and school level.

The effects of poliomyelitis on motor unit behavior during repetitive muscle actions: a case report.

PubMed

Trevino, Michael A; Herda, Trent J; Cooper, Michael A

2014-09-06

Acute paralytic poliomyelitis is caused by the poliovirus and usually results in muscle atrophy and weakness occurring in the lower limbs. Indwelling electromyography has been used frequently to investigate the denervation and innervation characteristics of the affected muscle. Recently developed technology allows the decomposition of the raw surface electromyography signals into the firing instances of single motor units. There is limited information regarding this electromyographic decomposition in clinical populations. In addition, regardless of electromyographic methods, no study has examined muscle activation parameters during repetitive muscle actions in polio patients. Therefore, the purpose of this study was to examine the motor unit firing rates and electromyographic amplitude and center frequency of the vastus lateralis during 20 repetitive isometric muscle actions at 50% maximal voluntary contraction in healthy subjects and one patient that acquired acute paralytic poliomyelitis. One participant that acquired acute type III spinal poliomyelitis (Caucasian male, age = 29 yrs) at 3 months of age and three healthy participants (Caucasian females, age = 19.7 ± 2.1 yrs) participated in this study. The polio participant reported neuromuscular deficiencies as a result of disease in the hips, knees, buttocks, thighs, and lower legs. None of the healthy participants reported any current or ongoing neuromuscular diseases or musculoskeletal injuries. An acute bout of poliomyelitis altered motor unit behavior, such as, healthy participants displayed greater firing rates than the polio patient. The reduction in motor unit firing rates was likely a fatigue protecting mechanism since denervation via poliomyelitis results in a reduction of motorneurons. In addition, the concurrent changes in motor unit firing rates, electromyography amplitude and frequency for the polio participant would suggest that the entire motorneuron pool was utilized in each contraction unlike for the healthy participants. Finally, healthy participants exhibited changes in all electromyographic parameters during the repetitive muscle actions despite successfully completing all contractions with only a slight reduction in force. Thus, caution is warranted when quantifying muscular fatigue via motor unit firing rates and other electromyographic parameters since the parameters changed despite successful completing of all contractions with only a moderate reduction in strength in healthy subjects.

The risk of adverse skin effects following light-based hair removal is greater in pigmented skin based on the theory of selective photothermolysis. Thus sunlight-induced pigment i.e., facultative pigmentation, increases the risk of adverse skin effects, perhaps disproportionately. The aim of this study was to evaluate the influence of constitutive and facultative skin pigmentation on low-fluence intense pulsed light (IPL)-induced adverse skin effects. Twenty-one subjects with Fitzpatrick skin type II-IV were enrolled. Two buttock blocks were randomized to receive 0 or 8 solar simulated ultraviolet radiation (UVR) exposures of consecutively increasing Standard Erythema Doses (2-4 SED). Each block was subdivided into four sites, randomized to receive IPL of 0, 7, 8, or 10 J/cm(2) , once a week for 3 weeks. Biopsies were taken 16-24 hours after the first IPL exposure and subjects were seen 1 and 4 weeks after the last IPL exposure. Outcome measures were: (i) skin reactions, (ii) pain, (iii) mRNA expression of pigment-markers microphthalmia-associated transcription factor (MITF) and pro-opiomelanocortin (POMC), and (iv) clinical appearance of biopsy wounds. Skin pigmentation increased after UVR (baseline median 13.8%, after UVR 28.1%, P = 0.0001) in all skin types. Subjects reported low pain intensities (median 1.5, scale 0-10) and experienced transient erythema immediately after IPL exposure. No persistent erythema, blisters, crusting, textual, or pigment changes were observed. The risk of erythema and pain intensities increased with IPL dose and skin pigmentation (P < 0.03). There was no difference in pain or skin reactions in skin with similar degree of natural and facultative pigmentation (P ≥ 0.104). Expression of cellular pigment-markers was not influenced by IPL exposure, neither in constitutive nor in facultative pigmented skin. Clinical appearance of biopsy wounds was unaffected by IPL exposure. The prevalence and intensity of low-fluence IPL-induced adverse skin effects depended on IPL dose and skin pigmentation regardless of the origin, i.e., constitutive versus UV induced. © 2013 Wiley Periodicals, Inc.

Cross-sectional study. To determine the correlation between SF-36 (a measure for overall health status in patients) and Oswestry-Disability Index (ODI) or Rolland-Morris Disability Questionnaire (RMDQ) confined to spine according to the type of pain from the spine. Data showed moderate correlation between ODI and SF-36 Physical Component Score (PCS), Physical Functioning (PF) (r=-0.46), Physical Role Functioning (RP) (r=-0.284), Bodily Pain (BP) (r=-0.327), and Mental Component Score (MCS), Emotional Role Functioning (r=-0.250), Social Role Functioning (r=0.254), Vitality (r=0.296). Between January 1, 2008 and December 31, 2013, a total of 69 patients were enrolled in this study. They were diagnosed with lumbar spinal stenosis and underwent decompression surgery such as laminotomy in this hospital. The 3 standardized questionnaires (ODI, RMDQ, and SF-36) were given to these patients, at least 1 year after the surgery. ODI and SF-36 had a statistically significant (P=0.001) and moderate correlation. Small correlations were also seen between Physical Functioning (r=-0.46), Physical Role Functioning (r=-0.284), and Bodily Pain (r=-0.327) of SF-36 PCS and ODI, and between Emotional Role Functioning (r=-0.250), Social Role Functioning (r=-0.254), and Vitality (r=-0.296) of SF-36 Mental Component Score and ODI. Items in ODI for the level of pain while standing and traveling were mostly related to axial back pain, while item of lifting was related to referred buttock pain. Sleeping disturbance section in the ODI was mainly caused by radiated leg pain. In addition, RMDQ was also associated to the 3 types of pain. Moderate correlation was found between ODI or RMDQ as a condition-specific outcome and the SF-36, indicating overall health status. ODI was found to be a more adequate measure to evaluate axial back pain rather than referred pain or radiating pain. RMDQ was adequate to measure the health status and to evaluate the 3 types of spine pain. These 3 instruments could therefore provide the clinician with complementary information about the patient's status.

Malignant melanoma is becoming an increasingly important problem in public health as incidence rates have been increasing continuously in Caucasian populations. Childhood and adolescence is an important time of life for the formation and evolution of nevi, and the presence of a higher number of nevi in early life could predict a major risk of developing melanoma. (1) To determine the number of nevi and the dermoscopic pattern predominance in children of our population. (2) To relate it to constitutional and environmental factors. Clinical and dermoscopic examinations were performed in 180 children aged 1-15 years. A questionnaire including topics such as past history of sunburns, tanning ability, tendency to sunburn, history of sunlight exposure, use of sunscreens, tendency to freckle and family history of cancer was completed in a face-to-face interview with the parents. On clinical examination, we evaluated hair color, eye color, number of nevi and the presence of nevi in specific locations. All melanocytic lesions were examined dermoscopically, and all patterns were registered as present or absent. We also registered the predominant dermoscopic pattern of the child, defined as being present in more than 40% of all of the individual's nevi. The mean number of moles was 17.5. Male gender, past history of sunburns, facial freckling and family history of breast cancer were independent risk factors for having a higher number of nevi. We found that 61.1% of children had nevi on the face and neck, 17.2% on the buttocks, 11.7% on the scalp, 19.4% had acral nevi and 31.7% had congenital nevi. We found the presence of nevi in some of these locations to be a risk factor for having a higher number of nevi. The most frequent dominant dermoscopic pattern found in our population was the globular type. Interestingly, we found that the homogeneous pattern predominates in the youngest children, the reticular pattern predominates in adolescents and the dominant globular pattern is constant among all ages evaluated. This is the first study clinically and dermoscopically characterizing nevi in children from our population, and evaluating constitutional and environmental risk factors. 2008 S. Karger AG, Basel

Individuals with spina bifida (SB) are vulnerable to chronic skin complications such as wounds on the buttocks and lower extremities. Most of these complications can be prevented with adherence to self-care routines. We have developed a mobile health (mHealth) system for supporting self-care and management of skin problems called SkinCare as part of an mHealth suite called iMHere (interactive Mobile Health and Rehabilitation). The objective of this research is to develop an innovative mHealth system to support self-skincare tasks, skin condition monitoring, adherence to self-care regimens, skincare consultation, and secure two-way communications between patients and clinicians. In order to support self-skincare tasks, the SkinCare app requires three main functions: (1) self-care task schedule and reminders, (2) skin condition monitoring and communications that include imaging, information about the skin problem, and consultation with clinician, and (3) secure two-way messaging between the patient and clinician (wellness coordinator). The SkinCare system we have developed consists of the SkinCare app, a clinician portal, and a two-way communication protocol connecting the two. The SkinCare system is one component of a more comprehensive system to support a wellness program for individuals with SB. The SkinCare app has several features that include reminders to perform daily skin checks as well as the ability to report skin breakdown and injury, which uses a combination of skin images and descriptions. The SkinCare app provides reminders to visually inspect one's skin as a preventative measure, often termed a "skin check." The data is sent to the portal where clinicians can monitor patients' conditions. Using the two-way communication, clinicians can receive pictures of the skin conditions, track progress in healing over time, and provide instructions for how to best care for the wound. The system was capable of supporting self-care and adherence to regimen, monitoring adherence, and supporting clinician engagement with patients, as well as testing its feasibility in a long-term implementation. The study shows the feasibility of a long-term implementation of skincare mHealth systems to support self-care and two-way interactions between patients and clinicians.

Mathematical model, combined with and verified using human subject data. (1) To develop and verify a lumped-parameter mathematical model for prediction of spine forces during backward falls; (2) to use this model to evaluate the effect of floor stiffness on spine forces during falls; and (3) to compare predicted impact forces with forces previously measured to fracture the spine. Vertebral fractures are the most common osteoporotic fractures and commonly result from falls from standing height. Compliant flooring reduces the force at the ground during a backward fall from standing; however, the effect on spine forces is unknown. A 6-df model of the body was developed and verified using data from 10 human subjects falling from standing onto 3 types of compliant floors (soft: 59 kN/m, medium: 67 kN/m, and firm: 95 kN/m). The simulated ground forces were compared with those measured experimentally. The model was also used to assess the effect of floor stiffness on spine forces at various intervertebral levels. There was less than 14% difference between model predictions and experimentally measured peak ground reaction forces, when averaged over all floor conditions. When compared with the rigid floor, average peak spine force attenuations of 46%, 43%, and 41% were achieved with the soft, medium, and firm floors, respectively (3.7, 3.9, 4.1 kN vs. 6.9 kN at L4/L5). Spine forces were lower than those at the ground and decreased cranially (4.9, 3.9, 3.7, 3.5 kN at the ground, L5/S1, L4/L5, and L3/L4, respectively, for the soft floor). Lowering the floor stiffness (from 400 to 59 kN/m) can attenuate peak lumbosacral spine forces in a backward fall onto the buttocks from standing by 46% (average peak from 6.9 to 3.7 kN at L4/L5) to values closer to the average tolerance of the spine to fracture (3.4 kN).

Soft tissue exhibits nonlinear stress-strain behavior under compression. Characterizing its nonlinear elasticity may aid detection, diagnosis, and treatment of soft tissue abnormality. The purposes of this study were to develop a rate-controlled Mechano-Acoustic Indentor System and a corresponding finite element optimization method to extract nonlinear elastic parameters of soft tissue and evaluate its test-retest reliability. An indentor system using a linear actuator to drive a force-sensitive probe with a tip-mounted ultrasound transducer was developed. Twenty independent sites at the upper lateral quadrant of the buttock from 11 asymptomatic subjects (7 men and 4 women from a chiropractic college) were indented at 6% per second for 3 sessions, each consisting of 5 trials. Tissue thickness, force at 25% deformation, and area under the load-deformation curve from 0% to 25% deformation were calculated. Optimized hyperelastic parameters of the soft tissue were calculated with a finite element model using a first-order Ogden material model. Load-deformation response on a standardized block was then simulated, and the corresponding area and force parameters were calculated. Between-trials repeatability and test-retest reliability of each parameter were evaluated using coefficients of variation and intraclass correlation coefficients, respectively. Load-deformation responses were highly reproducible under repeated measurements. Coefficients of variation of tissue thickness, area under the load-deformation curve from 0% to 25% deformation, and force at 25% deformation averaged 0.51%, 2.31%, and 2.23%, respectively. Intraclass correlation coefficients ranged between 0.959 and 0.999, indicating excellent test-retest reliability. The automated Mechano-Acoustic Indentor System and its corresponding optimization technique offers a viable technology to make in vivo measurement of the nonlinear elastic properties of soft tissue. This technology showed excellent between-trials repeatability and test-retest reliability with potential to quantify the effects of a wide variety of manual therapy techniques on the soft tissue elastic properties.

To evaluate the result of releasing adult intramuscular injection associated gluteal muscle contracture under the monitor of arthroscope by radiofrequency probe. From June 2001 to June 2005, 108 cases of bilateral gluteal muscle contracture were treated with radiofrequency colation under the arthroscope and solution with an average age of 24 years (from 18 to 40 years). There were 57 males and 51 females. Preoperatively, the course of the outline of the femur greater trochanter the sciatic nerve in buttocks and the area of gluteal muscle contracture were marked. With the patients firmly anchored in the straight lateral position, normal saline (which contains Adnephrin) was injected between the surface of contracted gluteus and subcutaneous fat to reduce bleeding in operation. The ports for the motorized shaver and radiofrequency probe were located at the edge of gluteal muscle contracture and were 5 mm superior to the greater trochanter. The 6 mm diameter port for the arthroscope was 3 cm inferior to the greater trochanter. Space was made between contracture bands and overlying subcutaneous tissue with a periosteal elevator by blunt dissection. After the anterior and posterior edge of the contracture bands were fully revealed, normal saline were filled in the space. With the monitor of arthroscope, the procedures were: removing fatty tissue from the surface of the contracture bands with motorized shaver, then cutting off the contracture bands curve and carefully probing and cutting off contracture bands which were mixed in gluteus maximus with radiofrequency probe, finally hemostasis by radiofrequency probe. In the operation flexion, adduction, internal rotation and straightening hip joint were repeated, until it got normal range of motion without snap and bleeding. Results One hundred and one patients were followed up with an average of 19 months. According to a comprehensive evaluating system, 91 cases were excellent, 7 were good, and 3 were fair. No infection, recurrence and neurovascular injury occurred. Gluteal muscle contracture could be effectively released with radiofrequency vaporization and solution. The technique has the advantage of easy to manipulate, minimally invasive, painless, safety and reliable curative effect, and is good for early functional exercises.

Background Minimally invasive sacroiliac joint fusion (SIJF) has become an increasingly accepted surgical option for chronic sacroiliac (SI) joint dysfunction, a prevalent cause of unremitting low back/buttock pain. Objective The objective of this study was to report clinical and functional outcomes of SIJF using triangular titanium implants (TTI) in the treatment of chronic SI joint dysfunction due to degenerative sacroiliitis or sacroiliac joint (SIJ) disruption at 3 years postoperatively. Methods A total of 103 subjects with SIJ dysfunction at 12 centers were treated with TTI in two prospective clinical trials (NCT01640353 and NCT01681004) and enrolled in this long-term follow-up study (NCT02270203). Subjects were evaluated in study clinics at study start and again at 3, 4, and 5 years. Results Mean (SD) preoperative SIJ pain score was 81.5, and mean preoperative Oswestry Disability Index (ODI) was 56.3. At 3 years, mean pain SIJ pain score decreased to 26.2 (a 55-point improvement from baseline, p<0.0001). At 3 years, mean ODI was 28.2 (a 28-point improvement from baseline, p<0.0001). In all, 82% of subjects were very satisfied with the procedure at 3 years. EuroQol-5D (EQ-5D) time trade-off index improved by 0.30 points (p<0.0001). No adverse events definitely related to the study device or procedure were reported; one subject underwent revision surgery at year 3.7. SIJ pain contralateral to the originally treated side occurred in 15 subjects of whom four underwent contralateral SIJF. The proportion of subjects who were employed outside the home full- or part-time at 3 years decreased somewhat from baseline (p=0.1814), and the proportion of subjects who would have the procedure again was lower at 3 years compared to earlier time points. Conclusion In long-term (3-year) follow-up, minimally invasive trans-iliac SIJF with TTI was associated with improved pain, disability, and quality of life with relatively high satisfaction rates. Level of evidence Level II. Clinical relevance SIJF with TTI. PMID:29674852

Summary Absolute ethanol is the most effective agent in the treatment of venous malformation (VM) although it is quite risky to use because of the danger of diffusion beyond the target. To reduce this risk, we have developed an alcoholic sclerosing solution that is less diffusible. The viscosity of absolute ethanol was enhanced with monographic ethyl-cellulose at a concentration of 5.88% ie 0.75 g in 15 ml of absolute ethanol 95%. 23 patients with VM located on the buttock (1), hand (2), leg (1) and face (19) were treated. A mean volume of 1.99 ml of the solution was injected directly into the VM. Each patient had an average of 2.8 procedures. Sixteen patients were done under general anaesthesia and seven with local anaesthesia. Evaluation was performed by the patient, the dermatologist of the treating multidisciplinary team and a dermatological group not involved in the treatment of the patients. Patients were evaluated after a mean delay of 24.52 months. Evaluation of the cosmetic result was made with a five point scale and the global result with a three point scale. VM pain was evaluated by the patients with a Visual Analogue Scale. The aesthetic results were graded as satisfactory (> 3) for the patient and the dermatologist of the multidisciplinary team. However the results were not as good with the independent dermatological group evaluation. The pain was significantly less important after the treatment (p << 0.001). Among the 23 patients, the local adverse events were nine necrosis with or without ethylcellulose fistula followed by only two surgical procedures. There were no systemic adverse events. Sclerotherapy of VM is usually performed with absolute ethanol or ethibloc. The main advantage of our sclerosing mixture is that it expands like a balloon when injected slowly in a aqueous media. Because of the important increase in viscosity the volume of injected solution is much lower than ethanol alone and the risk of systemic reactions is lower. Contrary to ethibloc, post-sclerosing surgery is not necessary because sub-cutaneous ethylcellulose disappears secondarily. PMID:20587223

Ergonomic risk at work stations with type Seated Work Control was one of the problems faced by Transjakarta bus driver. Currently “Trisakti” type bus, one type of bus that is used by Transjakarta in corridor 9, serving route Pinang Ranti - Pluit, gained many complaints from drivers. From the results of Nordic Body Map questionnaires given to 30 drivers, it was known that drivers feel pain in the neck, arms, hips, and buttocks. Allegedly this was due to the seat position and the button/panel bus has a considerable distance range (1 meter) to be achieved by drivers. In addition, preliminary results of the questionnaire using Workstation Checklist identified their complaints about uncomfortable cushion, driver's seat backrest, and the exact position of the AC is above the driver head. To reduce the risk level of ergonomics, then did research to design the cabin by using a generic approach to designing products. The risk analysis driver posture before the design was done by using Rapid Upper Limb Assessment (RULA), Rapid Entire Body Assessment (REBA), and Quick Exposure Checklist (QEC), while the calculation of the moment the body is done by using software Mannequin Pro V10.2. Furthermore, the design of generic products was done through the stages: need metric-matrix, house of quality, anthropometric data collection, classification tree concept, concept screening, scoring concept, design and manufacture of products in the form of two-dimensional. While the design after design risk analysis driver posture was done by using RULA, REBA, and calculation of moments body as well as the design visualized using software 3DMax. From the results of analysis before the draft design improvements cabin RULA obtained scores of 6, REBA 9, and the result amounted to 57.38% QEC and moment forces on the back is 247.3 LbF.inch and on the right hip is 72.9 LbF.in. While the results of the proposed improvements cabin design RULA obtained scores of 3, REBA 4, and the moment of force on the back is 90.3 LbF.in and on the right hip is 70.6 LbF.in. This indicated improvement cabin design can reduce ergonomic risk with lower scores on several parts of the body.

The overall goal of this project is to develop interventions for the prevention of deep tissue injury (DTI), a form of pressure ulcers that originates in deep tissue around bony prominences. The present study focused on: (1) obtaining detailed measures of the distribution of pressure experienced by tissue around the ischial tuberosities, and (2) investigating the effectiveness of intermittent electrical stimulation (IES), a novel strategy for the prevention of DTI, in alleviating pressure in regions at risk of breakdown due to sustained loading. The experiments were conducted in adult pigs. Five animals had intact spinal cords and healthy muscles and one had a spinal cord injury that led to substantial muscle atrophy at the time of the experiment. A force-controlled servomotor was used to load the region of the buttocks to levels corresponding to 25%, 50% or 75% of each animal's body weight. A pressure transducer embedded in a catheter was advanced into the tissue to measure pressure along a three dimensional grid around the ischial tuberosity of one hind leg. For all levels of external loading in intact animals, average peak internal pressure was 2.01 ± 0.08 times larger than the maximal interfacial pressure measured at the level of the skin. In the animal with spinal cord injury, similar absolute values of internal pressure as that in intact animals were recorded, but the substantial muscle atrophy produced larger maximal interfacial pressures. Average peak internal pressure in this animal was 1.43 ± 0.055 times larger than the maximal interfacial pressure. Peak internal pressure was localized within a ±2 cm region medio-laterally and dorso-ventrally from the bone in intact animals and ±1 cm in the animal with spinal cord injury. IES significantly redistributed internal pressure, shifting the peak values away from the bone in spinally intact and injured animals. These findings provide critical information regarding the relationship between internal and interfacial pressure around the ischial tuberosities during loading levels equivalent to those experienced while sitting. The information could guide future computer models investigating the etiology of DTI, as well as inform the design and prescription of seating cushions for people with reduced mobility. The findings also suggest that IES may be an effective strategy for the prevention of DTI.

Background Manual anthropometric measurements are time-consuming and challenging to perform within acceptable intra- and inter-individual error margins in large studies. Three-dimensional (3D) laser body scanners provide a fast and precise alternative: within a few seconds the system produces a 3D image of the body topography and calculates some 150 standardised body size measurements. Objective The aim was to enhance the small number of existing validation studies and compare scan and manual techniques based on five selected measurements. We assessed the agreement between two repeated measurements within the two methods, analysed the direct agreement between the two methods, and explored the differences between the techniques when used in regressions assessing the effect of health related determinants on body shape indices. Methods We performed two repeated body scans on 123 volunteering young men using a Vitus Smart XXL body scanner. We manually measured height, waist, hip, buttock, and chest circumferences twice for each participant according to the WHO guidelines. The participants also filled in a basic questionnaire. Results Mean differences between the two scan measurements were smaller than between the two manual measurements, and precision as well as intra-class correlation coefficients were higher. Both techniques were strongly correlated. When comparing means between both techniques we found significant differences: Height was systematically shorter by 2.1 cm, whereas waist, hip and bust circumference measurements were larger in the scans by 1.17–4.37 cm. In consequence, body shape indices also became larger and the prevalence of overweight was greater when calculated from the scans. Between 4.1% and 7.3% of the probands changed risk category from normal to overweight when classified based on the scans. However, when employing regression analyses the two measurement techniques resulted in very similar coefficients, confidence intervals, and p-values. Conclusion For performing a large number of measurements in a large group of probands in a short time, body scans generally showed good feasibility, reliability, and validity in comparison to manual measurements. The systematic differences between the methods may result from their technical nature (contact vs. non-contact). PMID:28289559

In a prior study, the Armstrong Laboratory (AL) demonstrated that +G(sub z) protection during simulated shuttle reentry could be improved with an extended coverage anti-G suit with pressure socks but no abdominal bladder (REAGS). In a subsequent study conducted at the NASA Johnson Space Center it was shown that REAGS had a down side which included restricted mobility (during simulated shuttle egress) and a larger boot size needed for the pressure socks. The present study was conducted using a modified REAGS to increase mobility during egress. The size of the crotch opening was increased, and the fabric covering the buttocks was replaced with more elastic material. Six healthy male members of the AL centrifuge panel served as subjects for the study. As in the earlier study, subjects received 20 to 35 mg of IV Lasix approximately 6 hours before being exposed to a simulated space shuttle reentry +G(sub z) profile on the AL centrifuge, which induced a mean weight loss of 2.8 percent, range 2.1 percent to 3.7 percent. The REAGS was inflated to 1.0 psig 10 minutes prior to G onset. The G-profile was identical to that used in the previous REAGS study. Physiologic parameters monitored were also the same, i.e., eye-level systolic blood pressure (ELBP) using the Finapres digital cuff technique and heart rate and rhythm. Subjective comments were obtained from questionnaires administered after the increased G exposure. Systolic ELBP was maintained at 60 mm Hg or above by pressurizing the anti-G suit in 0.5 psig increments up to a maximum pressure of 2.5 psig. There were no significant differences in mean G-suit pressure required to maintain systolic ELBP at 60 mm Hg or above between the REAGS worn with and without pressure socks. Maximum mean G-levels achieved during the GOR were also the same under both experimental conditions, i.e., 4.7 G with socks and 4.6 G without socks. These G-levels were essentially the same as recorded earlier with the unmodified REAGS. There were no significant differences in comfort rating during the G exposure assigned by subjects when they wore the modified REAGS with or without the pressure socks.

Information about injuries and its differences in Cliff Diving (CD) and Splash Diving (SD) are unknown. It was the aim to analyse (1) injury rates, patterns and causes; (2) differences (in injuries) between both disciplines; and to (3) identify targets for future injury prevention interventions. From April to November 2013, 81 cliff and 51 splash divers were prospectively surveyed with an encrypted, monthly e-mail-based questionnaire. During a total of 7857h diving with an average diving height of 13 (±7)m, an overall injury rate of 7.9 injuries/1000h of sport exposure was reported. Cliff divers most commonly suffered from injuries of the foot and ankle (18%; n=24) and neck and cervical spine (14%; n=19). In SD, the lower limb (52%; n=43) and lower back (23%; n=19) were most frequently involved. In 79% (n=49) of the cases, the injury happened while entering the water. Cliff divers were in 52% (n=15) of the injuries in a feet-first and in 14% (n=4) in a head-first position. Splash divers were in 45% (n=9) of the injuries in a back- or buttocks-first position. Most of the injuries were bruises (47%; n=104) and muscle strains (13%; n=28). The injury risk during practice was significantly higher than in competition (11.3 vs. 4.5 injuries/1000h; OR 2.5; p=0.001). The injury risk of experts (15.4/1000h exposure) was significantly higher than in professionals (6.3/1000h exposure; OR 2.4; 95% CI, 3.3-1.9; p<0.001), although the average diving height was significantly higher in professionals (19m±8 vs. 12m±6; p<0.001). Significantly more professionals performed dryland training compared to experts (p=0.006). Most of the injuries are related to the water entry. The entry position plays a key role in injury patterns with pursuant differences comparing CD with SD. Although most of the injuries involved soft-tissue only, severe injuries have been reported. Targets for future injury prevention strategies include protection for the increased impaction at entry; adaption of the diving conditions in practice to those in competition; dryland training courses; and instruction of non-professional divers to teach appropriate diving techniques.

We investigated the prevalence of groin pain in patients with sacroiliac joint (SIJ) dysfunction, lumbar spinal canal stenosis (LSS), and lumbar disc herniation (LDH) who did not have hip disorders, and evaluated the clinical features that distinguished SIJ dysfunction from LSS and LDH. We evaluated 127 patients (57 men, 70 women, average age 55 years) with SIJ dysfunction, 146 (98 men, 48 women, average age 71 years) with LSS, and 124 (83 men, 41 women, average age 50 years) with LDH. The following data were retrospectively collected from the patients' medical charts: (1) the prevalence of groin pain for each pathology; (2) corresponding spinal level of LSS and LDH in the patients with groin pain; (3) the pain areas in the buttocks and back; pain increase while in positions such as sitting, lying supine, and side-lying; an SIJ shear test; and four tender points composed of the posterior superior iliac spine (PSIS), long posterior sacroiliac ligament (LPSL), sacrotuberous ligament (STL), and iliac muscle. Fifty-nine (46.5%) patients with SIJ dysfunction, 10 (6.8%) with LSS, and 10 (8.1%) with LDH reported groin pain. Of the 10 patients with LSS, five presented with cauda equina symptoms, two had stenosis of L2-L3, and three had stenosis below L3-L4. The other five presented with radiculopathy: the corresponding nerve root was L2, L3, and L4 in one patient each, and L5 in two. Of the 10 patients with LDH, eight presented with radiculopathy: the corresponding nerve root was L2 and L4 in three patients each, and L5 in two. Two patients presented with L4-L5 discogenic pain without radiculopathy. In patients with groin pain, pain provoked by the SIJ shear test and the tenderness of the PSIS and LPSL were significant physical signs that differentiated SIJ dysfunction from LSS and LDH. (Fisher's exact test, P<0.05) CONCLUSION: The prevalence of groin pain in patients with SIJ dysfunction was higher than in those with LSS or LDH. When patients who do not have hip disorders complain of groin and lumbogluteal pain, not only lumbar disorders but also SIJ dysfunction should be considered. Copyright © 2017.

Scrub typhus is becoming a clinically important cause of acute undifferentiated febrile illness in Taiwan. The incubation period is between 6 and 21 days after exposure. It is transmitted by chiggers (larva of trombiculid mite) in long grasses and in dirt-floor homes, with infection characterized by a flu-like illness of fever, headache, and myalgia lasting approximately 1 week. It has various systemic manifestations, including GI symptoms. In some, the illness progresses to multiorgan dysfunction syndrome and death. We report on a 13-year-old boy who lived in Taipei City and who had initially tentative diagnosis of acute pyrexia of unknown origin with high fever up to 40.3°C for 1 week, but later had thrombocytopenia and diffuse abdominal pain with peritoneal sign suspected acute appendicitis. During the clinical course, septic shock and disseminated intravascular coagulopathy (DIC) were noted. There were skin rash in his trunk and extremities and an eschar with black crust surrounded by a scaling erythematous rim on his right buttock. In addition, we got the information of his travel history in Green Island and Orchid Island for 10 days.With the correct antibiotics, vancomycin, meropenem, and doxycycline, the patient was getting better and corresponding with high level of granulysin and tumor necrosis factor-alpha. The diagnosis of scrub typhus was confirmed by the biopsy of eschar and high quantitative real-time polymerase chain reaction values of Orientia tsutsugamushi (16sRNA and 56 kDa) tested by Centers for Disease Control and Prevention, Taiwan. Histopathological findings of the eschar revealed the leukocytoclastic vasculitis, crust and thrombus formation with many gram-negative microorganisms, O. tsutsugamushi demonstrated by 47 kDa monoclonal antibody immunohistochemical stain and electromicroscopy. After the careful selection of appropriate antibiotics including meropenem, vancomycin, and doxycycline, he recovered and was subsequently discharged 7 days after admission. This case highlights that scrub typhus infection can mimic acute abdomen and septic shock with DIC. This rare presentation of acute abdomen and septic shock with thrombocytopenia and DIC caused by scrub typhus should remind physicians to be alert to the possibility of acute abdomen and febrile illness resulting from scrub typhus.

In the United States, major compression and burst type fractures (>20% height loss) of the lumbar spine occur as a result of motor vehicle crashes, despite the improvements in restraint technologies. Lumbar burst fractures typically require an axial compressive load and have been known to occur during a non-horizontal crash event that involve high vertical components of loading. Recently these fracture patterns have also been observed in pure horizontal frontal crashes. This study sought to examine the contributing factors that would induce an axial compressive force to the lumbar spine in frontal motor vehicle crashes. We searched the National Automotive Sampling System (NASS, 1993-2011) and Crash Injury Research and Engineering Network (CIREN, 1996-2012) databases to identify all patients with major compression lumbar spine (MCLS) fractures and then specifically examined those involved in frontal crashes. National trends were assessed based on weighted NASS estimates. Using a case-control study design, NASS and CIREN cases were utilized and a conditional logistic regression was performed to assess driver and vehicle characteristics. CIREN case studies and biomechanical data were used to illustrate the kinematics and define the mechanism of injury. During the study period 132 NASS cases involved major compression lumbar spine fractures for all crash directions. Nationally weighted, this accounted for 800 cases annually with 44% of these in horizontal frontal crashes. The proportion of frontal crashes resulting in MCLS fractures was 2.5 times greater in late model vehicles (since 2000) as compared to 1990s models. Belted occupants in frontal crashes had a 5 times greater odds of a MCLS fracture than those not belted, and an increase in age also greatly increased the odds. In CIREN, 19 cases were isolated as horizontal frontal crashes and 12 of these involved a major compression lumbar burst fracture primarily at L1. All were belted and almost all occurred in late model vehicles with belt pretensioners and buckets seats. Major compression burst fractures of the lumbar spine in frontal crashes were induced via a dynamic axial force transmitted to the pelvis/buttocks into the seat cushion/pan involving belted occupants in late model vehicles with increasing age as a significant factor.

Although all professionals oppose abusive physical punishment, nonabusive physical punishment is still controversial. The aim of the present study was (i) to determine parents' behavior regarding the discipline of their children using corporal punishment or other alternative disciplinary methods, (ii) to identify the different associated factors for corporal punishment, and (iii) to determine the association between exposure of the child to corporal punishment and his or her psychosocial well-being. A representative sample of 400 fifth-grade primary school children and their mothers were subjected to a cross-sectional survey. Mothers were subjected to a questionnaire to assess their behavior on corporal punishment and other disciplinary methods. The children were subjected to Coopersmith Self-Esteem Inventory to assess their self-esteem, and a questionnaire to assess their relationship with others. About three-quarter of children (76.3%) were corporally punished, and about half of them (46.2%) were punished on sites other than the extremities or buttocks. In 59.3% of them the frequency of the punishment ranged from once or twice/week to more than once/day, and it left marks in about 20%. Other disciplinary methods used by mothers were yelling/insulting (43.5%), taking away a toy or privilege (39.3%), discussing/explaining (9.5%), and time out (2.8%). The significant predictors of mothers' use of corporal punishment were male gender of the child (p < 0.01), rural origin of the father (p= 0.02), the mother's bad history of rearing experience (p < 0.01), and poor interparental relationship (p= 0.02). The relation between corporal punishment of children and their self-esteem was not statistically significant; however, corporally punished children scored lower on their relationship with others than noncorporally punished ones (Z= 2.60, p < 0.05). Corporal punishment is a widespread disciplinary method in Alexandria. The use of corporal punishment could have adverse effects on the child especially on his or her relationship with others. Planning an awareness-raising educational program for current and expectant parents is recommended, to promote positive nonviolent methods of child rearing, via the media and campaigns, and encouragement of political, community, and religious leaders; medical personnel; journalists; and sports and entertainment figures to share in these campaigns.
