    Full Text Available INTRODUCTION: Composite biomaterials designed for the repair of abdominal wall defects are composed of a mesh component and a laminar barrier in contact with the visceral peritoneum. This study assesses the behaviour of a new composite mesh by comparing it with two latest-generation composites currently used in clinical practice. METHODS: Defects (7x5cm created in the anterior abdominal wall of New Zealand White rabbits were repaired using a polypropylene mesh and the composites: Physiomesh(TM; Ventralight(TM and a new composite mesh with a three-dimensional macroporous polyester structure and an oxidized collagen/chitosan barrier. Animals were sacrificed on days 14 and 90 postimplant. Specimens were processed to determine host tissue incorporation, gene/protein expression of neo-collagens (RT-PCR/immunofluorescence, macrophage response (RAM-11-immunolabelling and biomechanical resistance. On postoperative days 7/14, each animal was examined laparoscopically to quantify adhesions between the visceral peritoneum and implant. RESULTS: The new composite mesh showed the lowest incidence of seroma in the short term. At each time point, the mesh surface covered with adhesions was greater in controls than composites. By day 14, the implants were fully infiltrated by a loose connective tissue that became denser over time. At 90 days, the peritoneal mesh surface was lined with a stable mesothelium. The new composite mesh induced more rapid tissue maturation than Physiomesh(TM, giving rise to a neoformed tissue containing more type I collagen. In Ventralight(TM the macrophage reaction was intense and significantly greater than the other composites at both follow-up times. Tensile strengths were similar for each biomaterial. CONCLUSIONS: All composites showed optimal peritoneal behaviour, inducing good peritoneal regeneration and scarce postoperative adhesion formation. A greater foreign body reaction was observed for Ventralight(TM. All composites induced

    The tensor fascia lata is a versatile flap with many uses in reconstructive plastic surgery. As a pedicled flap its reach to the lower abdomen and groin made it an attractive option for reconstructing soft tissue defects after tumor ablation. However, debate exists on the safe dimension of the flap, as distal tip necrosis is common. Also, the adequacy of the fascia lata as a sole substitute for abdominal wall muscles has been disputable. The aim of the current study is to report our experience and clinical observations with this flap in reconstructing those challenging defects and to discuss the possible options to minimize the latter disputable issues. Patients and Methods: From April 2001 to April 2004, 12 pedicled TFL flaps were used to reconstruct 5 central abdominal wall full thickness defects and 6 groin soft tissue defects following tumor resection. ]n one case, bilateral flaps were used to reconstruct a large central abdominal wall defect. There were 4 males and 7 females. Their age ranged from 19 to 60. From the abdominal wall defects group, all repairs were enforced primarily with a prolene mesh except for one patient who was the first in this study. Patients presenting with groin defects required coverage of exposed vessels following tumor resection. All patients in the current study underwent immediate reconstruction. The resulting soft tissue defects in this study were due to resection of 4 abdominal wall desmoid tumors, a colonic carcinoma infiltrating the abdominal wall, 4 primary groin soft developed in a flap used to cover a groin defect. In the former 3 cases, The flap was simply transposed without complete islanding of the flap. In the latter case, a very large flap was harvested beyond the safe limits with its distal edge just above the knee. In addition, wound dehiscence of the flap occurred in 2 other cases from the groin group. Nevertheless, all the wounds healed spontaneously with repeated dressings. Out of the 5 cases that underwent

    Conventional endoscopic resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are powerful tools for the treatment of gastrointestinal (GI) neoplasms. However, those techniques are limited to the superficial layers of the GI wall (mucosa and submucosa). Lesions without lifting sign (usually arising from deeper layers) or lesions in difficult anatomic positions (appendix, diverticulum) are difficult - if not impossible - to resect using conventional techniques, due to the increased risk of complications. For larger lesions (>2 cm), ESD appears to be superior to the conventional techniques because of the en bloc resection, but the procedure is technically challenging, time consuming, and associated with complications even in experienced hands. Since the development of the over-the-scope clips (OTSC), complications like bleeding or perforation can be endoscopically better managed. In recent years, different endoscopic full-thickness resection techniques came to the focus of interventional endoscopy. Since September 2014, the full-thickness resection device (FTRD) has the CE marking in Europe for full-thickness resection in the lower GI tract. Technically the device is based on the OTSC system and combines OTSC application and snare polypectomy in one step. This study shows all full-thickness resection techniques currently available, but clearly focuses on the experience with the FTRD in the lower GI tract.

    A method to determine ''full reflector thickness'' and ''isolation thickness'', which is utilized for criticality safety evaluation on nuclear fuel facilities, was proposed in this paper. Firstly, a calculation was tryed to obtain the two kinds of thicknesses from the result of criticality calculations for a specific case. Then, two simple equations which calculates the two kinds of thicknesses were made from the relation between reflector (or isolator) thickness and k eff , and one-group diffusion theory. Finally, we proposed a new method to determine the thicknesses. From the method we proposed, ''full reflector thickness'' and ''isolation thickness'' can be obtain using the equations and migration length of the reflector (or isolator) and infinite and effective multiplication factor of the fuel.

    Full Text Available Background: Magnetic anchored surgical instruments (MASI, relying on magnetic force, can break through the limitations of the single port approach in dexterity. Individual characteristic abdominal wall thickness (ICAWT deeply influences magnetic force that determines the safety of MASI. The purpose of this study was to research the abdominal wall characteristics in MASI applied environment to find ICAWT, and then construct an artful method to predict ICAWT, resulting in better safety and feasibility for MASI. Methods: For MASI, ICAWT is referred to the thickness of thickest point in the applied environment. We determined ICAWT through finding the thickest point in computed tomography scans. We also investigated the traits of abdominal wall thickness to discover the factor that can be used to predict ICAWT. Results: Abdominal wall at C point in the middle third lumbar vertebra plane (L3 is the thickest during chosen points. Fat layer thickness plays a more important role in abdominal wall thickness than muscle layer thickness. "BMI-ICAWT" curve was obtained based on abdominal wall thickness of C point in L3 plane, and the expression was as follow: f(x = P1 × x 2 + P2 × x + P3, where P1 = 0.03916 (0.01776, 0.06056, P2 = 1.098 (0.03197, 2.164, P3 = −18.52 (−31.64, −5.412, R-square: 0.99. Conclusions: Abdominal wall thickness of C point at L3 could be regarded as ICAWT. BMI could be a reliable predictor of ICAWT. In the light of "BMI-ICAWT" curve, we may conveniently predict ICAWT by BMI, resulting a better safety and feasibility for MASI.

    Conventional endoscopic resection techniques such as endoscopic mucosal resection or endoscopic submucosal dissection are powerful tools for treatment of gastrointestinal neoplasms. However, those techniques are restricted to superficial layers of the gastrointestinal wall. Endoscopic full-thickness resection (EFTR) is an evolving technique, which is just about to enter clinical routine. It is not only a powerful tool for diagnostic tissue acquisition but also has the potential to spare surgical therapy in selected patients. This review will give an overview about current EFTR techniques and devices.

    Full Text Available Abstract Introduction Extrauterine abdominal pregnancy is extremely rare and is frequently missed during antenatal care. This is a report of a full-term extrauterine abdominal pregnancy in a primigravida who likely had a ruptured ectopic pregnancy with secondary implantation and subsequently delivered a healthy baby. Case presentation A 23-year-old, Middle Eastern, primigravida presented at 14 weeks gestation with intermittent suprapubic pain and dysuria. An abdominal ultrasound examination showed a single viable fetus with free fluid in her abdomen. A follow-up examination at term showed a breech presentation and the possibility of a bicornute uterus with the fetus present in the left horn of her uterus. Our patient underwent Cesarean delivery under general anesthesia and was found to have a small intact uterus with the fetus lying in her abdomen and surrounded by an amniotic fluid-filled sac. The baby was extracted uneventfully, but the placenta was implanted in the left broad ligament and its removal resulted in massive intraoperative bleeding that necessitated blood and blood products transfusion and the administration of Factor VII to control the bleeding. Both the mother and newborn were discharged home in good condition. Conclusions An extrauterine abdominal pregnancy secondary to a ruptured ectopic pregnancy with secondary implantation could be missed during antenatal care and continue to term with good maternal and fetal outcome. An advanced extrauterine pregnancy should not result in the automatic termination of the pregnancy.

    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 Abdominal circumference also decreased significantly in the participants (11.3 ± 6.7 cm, P abdominal fat thickness decreased significantly in the participants (2.3 ± 1.1 cm, P abdominal fat thickness as well as the waist circumference without causing any side effect.

    Full Text Available Sebaceous gland carcinoma is an aggressive, uncommon, cutaneous malignancy. This tumour can arise anywhere in the body; approximately 75% of these tumours arise in the periocular region. The diagnosis and management of these malignancies often tend to get delayed because they are frequently mistaken for more common benign entities. Surgery has been and remains the primary treatment modality for sebaceous gland carcinomas. The resultant surgical defects following tumour excision generally tend to be full thickness and reconstructions of such defects pose significant challenges. These defects are conventionally reconstructed by the traditional bridging (eyelid sharing procedures, that is, the Cutler-Beard flap and its modifications. The ′Switch flap′ is an alternative eyelid sharing procedure; however, it is not very widely practiced. We recently used this procedure to reconstruct a large full-thickness upper eyelid defect with a satisfactory cosmetic and functional outcome.

    Full Text Available AIM: To compare choroidal thickness at the macula in eyes with unilateral idiopathic full-thickness macular holes(FTMHwith that of unaffected fellow eyes, and eyes of normal control patients.METHODS: Cross-sectional study. Thirty patients with unilateral idiopathic FTMH and thirty age, sex, and race-matched controls were recruited. Axial lengths were measured using laser interferometry. Enhanced depth imaging optical coherence tomography images were obtained using Heidelberg spectral-domain optical coherence tomography. Choroidal thickness was measured at the fovea, and at 1 mm and 2 mm nasally, temporally, superiorly and inferiorly from the center of the fovea. Statistical analysis was performed using independent and paired t-tests, chi-square tests, and Pearson correlation tests(PRESULTS: The mean subfoveal choroidal thickness was 201.0±44.0 μm in the FTMH group, 225.3±51.4 μm in the fellow eye group and 262.3±70.3 μm in the control group. The choroid was thinner in FTMH eyes at all locations when compared to control eyes(PPP>0.05. Choroidal thickness was generally highest subfoveally and lowest nasally. Subfoveal choroidal thickness was negatively correlated with age(r=-0.278, P=0.032, and axial length(r=-0.328, P=0.011.CONCLUSION: Choroidal thickness is lower in both eyes of patients with unilateral FTMH compared to healthy control eyes.

    Endoscopic resection of duodenal non-lifting adenomas and subepithelial tumors is challenging and harbors a significant risk of adverse events. We report on a novel technique for duodenal endoscopic full-thickness resection (EFTR) by using an over-the-scope device. Data of 4 consecutive patients who underwent duodenal EFTR were analyzed retrospectively. Main outcome measures were technical success, R0 resection, histologic confirmation of full-thickness resection, and adverse events. Resections were done with a novel, over-the-scope device (full-thickness resection device, FTRD). Four patients (median age 60 years) with non-lifting adenomas (2 patients) or subepithelial tumors (2 patients) underwent EFTR in the duodenum. All lesions could be resected successfully. Mean procedure time was 67.5 minutes (range 50-85 minutes). Minor bleeding was observed in 2 cases; blood transfusions were not required. There was no immediate or delayed perforation. Mean diameter of the resection specimen was 28.3 mm (range 22-40 mm). Histology confirmed complete (R0) full-thickness resection in 3 of 4 cases. To date, 2-month endoscopic follow-up has been obtained in 3 patients. In all cases, the over-the-scope clip was still in place and could be removed without adverse events; recurrences were not observed. EFTR in the duodenum with the FTRD is a promising technique that has the potential to spare surgical resections. Modifications of the device should be made to facilitate introduction by mouth. Prospective studies are needed to further evaluate efficacy and safety for duodenal resections. Copyright © 2015 American Society for Gastrointestinal Endoscopy. Published by Elsevier Inc.

    The study was designed to evaluate the intra-examiner reliability of ultrasound (US) thickness measurement of abdominal muscles activity when supine lying and during two isometric endurance tests in subjects with and without Low back pain (LBP). A total of 19 women (9 with LBP, 10 without LBP) participated in the study. Within-day reliability of the US thickness measurements at supine lying and the two isometric endurance tests were assessed in all subjects. The intra-class correlation coefficient (ICC) was used to assess the relative reliability of thickness measurement. The standard error of measurement (SEM), minimal detectable change (MDC) and the coefficient of variation (CV) were used to evaluate the absolute reliability. Results indicated high ICC scores (0.73-0.99) and also small SEM and MDC scores for within-day reliability assessment. The Bland-Altman plots of agreement in US measurement of the abdominal muscles during the two isometric endurance tests demonstrated that 95% of the observations fall between the limits of agreement for test and retest measurements. Together the results indicate high intra-tester reliability for the US measurement of the thickness of abdominal muscles in all the positions tested. According to the study's findings, US imaging can be used as a reliable method for assessment of abdominal muscles activity in supine lying and the two isometric endurance tests employed, in participants with and without LBP.

    The surgical site infection (SSI) is a common complication of abdominal operation. It relates to increased hospital stay, increased healthcare cost, and decreased patient's quality of life. Obesity, usually defined by BMI, is known as one of the risks of SSI. However, the thickness of subcutaneous layers of abdominal wall might be an important local factor affecting the rate of SSI after the abdominal operations. The objective of this study is to assess the importance of the abdominal wall thickness on incisional SSI rate. The subjects of the present study were patients who had undergone major abdominal operations at Thammasat University Hospital between June 2013 and May 2014, and had been investigated with CT scans before their operations. The demographic data and clinical information of these patients were recorded. The thickness ofsubcutaneous fatty tissue from skin down to the most superficial layer of abdominal wall muscle at the surgical site was measured on CT images. The wound infectious complication was reviewed and categorized as superficial and deep incisional SSIfollowing the definition from Centersfor Disease Control and Prevention (CDC) guidelines. The significance ofeach potentialfactors on SSI rates was determined separately with student t-test for quantitative data and χ2-test for categorical data. Then all factors, which had p operative CTscans. Post-operative SSI was 25.2% (35/139), superficial and deep types in 27 and 8 patients, respectively. The comparison of abdominal wall thickness between patients with and without infection was significantly different (20.0 ± 8.4 mm and 16.0 ± 7.2 mm, respectively). When the thickness at 20 mm was used as the cut-off value, 43 of 139 patients had abdominal wall thickness ≥ 20 mm. The incidence of SSI of the thickness ±20 mm group was 37.2% (16/43) and of the less thickness group was 19.8% (19/96), with p operation. However, only abdominal wall thickness and wound classification were still significant

    Subcutaneous fat layer thickness in the abdomen is a risk indicator of several diseases and disorders like diabetes and heart problems and could be used as a measure of fitness. Skinfold measurement using mechanical calipers is simple but prone to error. Ultrasound scanning techniques are yet to be established as accurate methods for this purpose. magnetic resonance imaging (MRI) and computed tomography (CT) scans can provide the answer but are expensive and not available widely. Some initiatives were made earlier to use electrical impedance to this end, but had inadequacies. In the first part of this paper, a 4-electrode focused impedance method (FIM) with different electrode separations has been studied for its possible use in the determination of abdominal fat thickness in a localized region. For this, a saline phantom was designed to provide different electrode separations and different layers of resistive materials adjacent to the electrodes. The background saline simulated the internal organs having low impedance while the resistive layers simulated the subcutaneous fat. The plot of the measured impedance with electrode separation had different ‘slopes’ for different thicknesses of resistive layers, which offered a method to obtain an unknown thickness of subcutaneous fat layer. In the second part, measurements were performed on seven human subjects using two electrode separations. Fat layer thickness was measured using mechanical calipers. A plot of the above ‘slope’ against fat thickness could be fitted using a straight line with an R 2 of 0.93. Then this could be used as a calibration curve for the determination of unknown fat thickness. Further work using more accurate CT and MRI measurements would give a better calibration curve for practical use of this non-invasive and low-cost technique in abdominal fat thickness measurement.

    To evaluate the efficacy, safety and feasibility of endoscopic full-thickness resection (EFR) for the treatment of gastric submucosal tumors (SMTs) arising from the muscularis propria. A total of 35 gastric SMTs arising from the muscularis propria layer were resected by EFR between January 2010 and September 2013. EFR consists of five major steps: injecting normal saline into the submucosa; pre-cutting the mucosal and submucosal layers around the lesion; making a circumferential incision as deep as the muscularis propria around the lesion using endoscopic submucosal dissection and an incision into the serosal layer around the lesion with a Hook knife; a full-thickness resection of the tumor, including the serosal layer with a Hook or IT knife; and closing the gastric wall with metallic clips. Of the 35 gastric SMTs, 14 were located at the fundus, and 21 at the corpus. EFR removed all of the SMTs successfully, and the complete resection rate was 100%. The mean operation time was 90 min (60-155 min), the mean hospitalization time was 6.0 d (4-10 d), and the mean tumor size was 2.8 cm (2.0-4.5 cm). Pathological examination confirmed the presence of gastric stromal tumors in 25 patients, leiomyomas in 7 and gastric autonomous nerve tumors in 2. No gastric bleeding, peritonitis or abdominal abscess occurred after EFR. Postoperative contrast roentgenography on the third day detected no contrast extravasation into the abdominal cavity. The mean follow-up period was 6 mo, with no lesion residue or recurrence noted. EFR is efficacious, safe and minimally invasive for patients with gastric SMTs arising from the muscularis propria layer. This technique is able to resect deep gastric lesions while providing precise pathological information about the lesion. With the development of EFR, the indications of endoscopic resection might be extended.

    Abdominal obesity with visceral fat accumulation have been known to be intimately associated with the development of metabolic syndrome. Therefore, it is important to estimate the precise amount of visceral fat. Ultrasonography has been reported that it is a simple and noninvasive method for visceral fat evaluation. Purpose of this study is to evaluate the association of ultrasonographic visceral fat thickness, anthropometric indexes, and risk factor of metabolic syndrome, and to investigate the cut-off value of abdominal visceral fat thickness leading to increased risk of metabolic syndrome. The subject included 200 men and 200 women who visited D healthcare center in Daejeon from January to April 2008. The subcutaneous fat thickness and visceral fat thickness were measured by ultrasonograph. As anthropometric index, we measured body mass index, waist circumference and waist/height ratio. As for the risk factor of metabolic syndrome, we measured blood pressure, high density lipoprotein cholesterol, triglyceride and fasting serum glucose. VFT was significantly correlated with waist circumference, (r=0.683/M, r=0.604/F), waist to height ratio (r=0.633/M, r=0.593/F) and BMI (r=0.621/M, r=0.534/F) in both men and women. In addition it was significantly correlated with Systolic blood pressure (r=0.229/M, r=0.232/F), Diastolic blood pressure ((r=0.285/M, r=0.254/F), high density cholesterol (r=-0.254/M, r=-0.254/F), Triglyceride (r=0.475/M, r=0.411/F), and Fasting blood sugar (r=0.158/M, r=0.234/F) in both men and women. The cut-off value of visceral fat thickness leading to the increased risk of metabolic syndrome was 4.58 cm (sensitivity 89.2%, specificity 71.2%) in men and 3.50 cm (sensitivity 61.2% specificity 80.8%) in women respectively. The odds ratio of the risk of metabolic syndrome was dramatically increased with the abdominal visceral fat thickness level over 6 cm in men and 5 cm in women. The visceral fat thickness using ultrasonography was significantly

    Abdominal obesity with visceral fat accumulation have been known to be intimately associated with the development of metabolic syndrome. Therefore, it is important to estimate the precise amount of visceral fat. Ultrasonography has been reported that it is a simple and noninvasive method for visceral fat evaluation. Purpose of this study is to evaluate the association of ultrasonographic visceral fat thickness, anthropometric indexes, and risk factor of metabolic syndrome, and to investigate the cut-off value of abdominal visceral fat thickness leading to increased risk of metabolic syndrome. The subject included 200 men and 200 women who visited D healthcare center in Daejeon from January to April 2008. The subcutaneous fat thickness and visceral fat thickness were measured by ultrasonograph. As anthropometric index, we measured body mass index, waist circumference and waist/height ratio. As for the risk factor of metabolic syndrome, we measured blood pressure, high density lipoprotein cholesterol, triglyceride and fasting serum glucose. VFT was significantly correlated with waist circumference, (r=0.683/M, r=0.604/F), waist to height ratio (r=0.633/M, r=0.593/F) and BMI (r=0.621/M, r=0.534/F) in both men and women. In addition it was significantly correlated with Systolic blood pressure (r=0.229/M, r=0.232/F), Diastolic blood pressure ((r=0.285/M, r=0.254/F), high density cholesterol (r=-0.254/M, r=-0.254/F), Triglyceride (r=0.475/M, r=0.411/F), and Fasting blood sugar (r=0.158/M, r=0.234/F) in both men and women. The cut-off value of visceral fat thickness leading to the increased risk of metabolic syndrome was 4.58 cm (sensitivity 89.2%, specificity 71.2%) in men and 3.50 cm (sensitivity 61.2% specificity 80.8%) in women respectively. The odds ratio of the risk of metabolic syndrome was dramatically increased with the abdominal visceral fat thickness level over 6 cm in men and 5 cm in women. The visceral fat thickness using ultrasonography was significantly

    Abdominal wall flaps are routinely used in reconstructive procedures. In some patients inadequate venous drainage from the deep vein may cause fat necrosis or flap failure. Occasionally the superficial inferior epigastric vessels (SIEV) are of sufficient size to allow for microvascular revascularization. This study looked at the ratio of the sub- and suprascarpal fat layers, the number of deep system perforators, and SIEV diameter to determine any correlation of the fat topography and SIEV. 50 abdominal/pelvic CT angiograms (100 hemiabdomens) were examined in women aged 34-70 years for number of perforators, SIEV diameter, and fat pad thickness above and below Scarpa's fascia. Data was analyzed using multivariate model. The average suprascarpal and subscarpal layers were 18.6 ± 11.5 mm and 6.2 ± 7.2 mm thick, respectively. The average SIEV diameter was 2.06 ± 0.81 mm and the average number of perforators was 2.09 ± 1.03 per hemiabdomen. Hemiabdomens with suprascarpal thickness>23 mm had greater SIEV diameter [2.69 mm vs. 1.8 mm (P fat layer thickness did not correlate with the number of perforators. Neither subscarpal fat thickness nor suprascarpal-to-subscarpal fat layer thickness correlated significantly with SIEV caliber or number of perforators in multivariate model. Suprascarpal fat pad thicker than 23 mm had larger SIEVs irrespective of the number of deep system perforators. This may indicate a cohort of patients at risk of venous congestion from poor venous drainage if only the deep system is revascularized. We recommend harvesting the SIEV in patients with suprascarpal fat pad >23 mm to aid in superficial drainage. © 2015 Wiley Periodicals, Inc.

    Full Text Available PURPOSE: To compare the lateral abdominal muscle thickness and other possible functional risk factors in young soccer players with and without low back pain (LBP.METHOD: In total, 30 young soccer players between 16 and 20 years old, with and without LBP, from the premier league participated in this study. The thicknesses of external oblique, internal oblique and transversus abdominis on both sides were measured via ultrasound imaging. In addition, hamstring flexibility, active lumbar forward flexion, and isometric muscle endurance of trunk extensors were measured and were compared regarding the history of LBP.RESULTS: Mean ± SD age of the subjects was 17.4 ± 1.1 years. There was no statistically significant difference regarding age, BMI, weekly training hours and age of starting to compete between groups. Subjects with sports-life, last year and last month history ofLBP had a statistically significant lower external oblique muscle thickness in both right and left side, and both dominant and non-dominant feet (p<0.05. Subjects with sportslife history of LBP had lower internal oblique muscle thickness in both side and both feet (p<0.05. Moreover, those with a sports-life history of LBP had a significantly higher degree of hamstring muscle tightness than non-LBP group on the dominant foot (p <0.05.CONCLUSION: In this sample group of young soccer players, abdominal muscles seem to have an important role in the stability of the spine and prevention of LBP. Further longitudinal studies are needed to evaluate the role of these muscles as a risk factor for soccer players.

    Abdominal fat thickness is a risk indicator of heart diseases, diabetes, etc., and its measurement is therefore important from the point of view of preventive care. Tetrapolar electrical impedance measurements (TPIM) could offer a simple and low cost alternative for such measurement compared to conventional techniques using CT scan and MRI, and has been tried by different groups. Focused Impedance Method (FIM) appears attractive as it can give localised information. An intuitive physical model was developed and experimental work was performed on a phantom designed to simulate abdominal subcutaneous fat layer in a body. TPIM measurements were performed with varying electrode separations. For small separations of current and potential electrodes, the measured impedance changed little, but started to decrease sharply beyond a certain separation, eventually diminishing gradually to negligible values. The finding could be explained using the intuitive physical model and gives an important practical information. TPIM and FIM may be useful for measurement of SFL thickness only if the electrode separations are within a certain specific range, and will fail to give reliable results if beyond this range. Further work, both analytical and experimental, are needed to establish this technique on a sound footing.

    The purpose of this study was to effects of abdominal draw-in maneuver and core exercise with 4 weeks using the musculoskeletal ultrasonography on muscle thickness and disability in subjects with low back pain. Twenty patients with nonspecific back pain (abdominal draw-in maneuver group: n= 10, core exercise group: n= 10) were recruited in the study. Both group received exercise intervention 3 times a week for 4weeks. The test were based on muscle thickness (transversus abdominis; Tra, internal oblique; IO and external oblique; EO), disability (Oswestry disability index; ODI) measured immediately before and after intervention. The data was measured by SPSS program 12.0 version and analyzed by Paired t-test and Independent t-test. The following results were obtained. The thickness of IO, EO for both group significantly improved except for muscle thickness of Tra. The ODI were significant difference for both groups. As the results of this study, we suggest that it may be effective method to apply to increase for the thickness of Tra, EO using abdominal draw-in maneuver and thickness of IO using core exercise.

    The purpose of this study was to analyse the natural course of symptomatic full-thickness and partial-thickness rotator cuff tears treated non-operatively and to identify risk factors affecting tear enlargement. One hundred and twenty-two patients who received non-surgical treatment for a partial- or full-thickness supraspinatus tear were included in this study. All rotator cuff tears were diagnosed with magnetic resonance imaging (MRI), and the same modality was used for follow-up studies. Follow-up MRI was performed after at least a 6-month interval. We evaluated the correlation between tear enlargement and follow-up duration. Eleven risk factors were analysed by both univariate and multivariate analyses to identify factors that affect enlargement of rotator cuff tears. The mean follow-up period was 24.4 ± 19.5 months. Out of 122 patients, 34 (27.9%) patients had an initial full-thickness tear and 88 (72.1%) patients had a partial-thickness tear. Considering all patients together, tear size increased in 51/122 (41.8%) patients, was unchanged in 65/122 (53.3%) patients, and decreased in 6/122 (4.9%) patients. Tear size increased for 28/34 (82.4%) patients with full-thickness tears and 23/88 (26.1%) patients with partial-thickness tears. From the two groups which were followed over 12 months, a higher rate of enlargement was observed in full-thickness tears than in partial-thickness tears (6-12 months, n.s.; 12-24 months, P = 0.002; over 24 months, P rotator cuff tears and 23/88 (26.1%) of symptomatic partial-thickness tears increased in size over a follow-up period of 6-100 months. Full-thickness tears showed a higher rate of enlargement than partial-thickness tears regardless of the follow-up duration. Univariate and multivariate analyses suggested that full-thickness tear was the most reliable risk factor for tear enlargement. The clinical relevance of these observations is that full-thickness rotator cuff tears treated conservatively should be

    We report the case of a 10-year-old boy with a full thickness chemical burn on his right pretibial area due to phytophotodermatitis (PPD) following contact with giant hogweed (Heracleum mantegazzianum). Although cutaneous burns due to plants are a well-established cause of chemical burn, previous reports described partial thickness burns that healed with conservative measures. This patient presented to our unit two weeks after the initial injury with an established full thickness burn. Debridement and split thickness skin grafting was required. We presented the histological features of the debrided skin specimen and discussed potential factors leading to this unexpected full thickness injury.

    Recent developments have expanded the frontier of interventional endoscopy toward more extended resections following surgical principles. This article presents two new device-assisted techniques for endoscopic full-thickness resection in the upper and lower gastrointestinal tract. Both methods are nonexposure techniques avoiding exposure of gastrointestinal contents to the peritoneal cavity by a "close first-cut later" principle. The full-thickness resection device is a novel over-the-scope device designed for clip-assisted full-thickness resection of colorectal lesions. Endoscopic full-thickness resection of gastric subepithelial tumors can be performed after placing transmural sutures underneath the tumor with a suturing device originally designed for endoscopic antireflux therapy.

    Endoscopic full-thickness resection of gastric subepithelial tumors with a full-thickness suturing device has been described as feasible in two small case series. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this resection technique. After 31 patients underwent endoscopic full-thickness resection, the data were analyzed retrospectively. Before snare resection, 1 to 3 full-thickness sutures were placed underneath each tumor with a device originally designed for endoscopic anti-reflux therapy. All tumors were resected successfully. Bleeding occurred in 12 patients (38.7 %); endoscopic hemostasis could be achieved in all cases. Perforation occurred in 3 patients (9.6 %), and all perforations could be managed endoscopically. Complete resection was histologically confirmed in 28 of 31 patients (90.3 %). Mean follow-up was 213 days (range, 1 - 1737), and no tumor recurrences were observed. Endoscopic full-thickness resection of gastric subepithelial tumors with the suturing technique described above is feasible and effective. After the resection of gastrointestinal stromal tumors (GISTs), we did not observe any recurrences during follow-up, indicating that endoscopic full-thickness resection may be an alternative to surgical resection for selected patients. © Georg Thieme Verlag KG Stuttgart · New York.

    The hemostatic system cooperates with proteolytic degradation in processes allowing abdominal aortic aneurysm (AAA) formation. In previous studies, it has been suggested that aneurysm rupture depends on intraluminal thrombus (ILT) thickness, which varies across each individual aneurysm. We hypothesized that hemostatic components differentially accumulate in AAA tissue in relation to ILT thickness. Thick (A1) and thin (B1) segments of ILTs and aneurysm wall sections A (adjacent to A1) and B (adjacent to B1) from one aneurysm sac were taken from 35 patients undergoing elective repair. Factor levels were measured using enzyme-linked immunosorbent assay of protein extract. Tissue factor (TF) activities were significantly higher in thinner segments of AAA (B1 vs A1, P = .003; B vs A, P thick thrombus-covered wall segments (A) than in B, A1, and B1 (P = .015, P thick ILT (P = .021) and thick ILT (A1; P thick ILT (A1). However, no correlations were found at B sites, except for a correlation between plasmin and TF activities (r = 0.55; P = .004). These results suggest that higher TF activities are present in thinner AAA regions. These parameters and local fibrinolysis may be part of the processes leading to destruction of the aneurysm wall.

    Full Text Available Graft-assisted healing is an important strategy for treating full-thickness skin wounds. This study evaluated the properties of porcine cholecyst–derived scaffold and its use for treating full-thickness skin wound in rabbit. The physical properties of cholecyst-derived scaffold were congenial for skin-graft application. Compared to a commercially available skin-graft substitute made of porcine small intestinal submucosa, the cholecyst-derived scaffold was rich in natural biomolecules like elastin and glycosaminoglycans. When used as a xenograft, it promoted healing with excess cell proliferation at early phases and acceptable collagen deposition in the later remodelling phases.

    The potential of several drugs for full-thickness skin burns has been investigated, but the treatment of such burns remains a challenge in plastic surgery. The present study was designed to determine the effect of systemic and topical administration of piracetam and nimodipine on full-thickness skin burn wound healing. A total of 36 New Zealand male rabbits were divided into six groups. Full-thickness skin burns were produced in all the groups, except the control group. Piracetam was administered systemically (piracetam-IV) and topically (piracetam-C) for 14 days, and nimodipine was administered systemically (nimodipine-IV) and topically (nimodipine-C) over the burn wounds for 14 days. The sham group underwent burn injury but was not administered any drug. After 21 days, gross examination and histopathological analysis were performed and the results were compared statistically. Nimodipine-C and nimodipine-IV had no effect on burn wound healing. However, both piracetam-IV and piracetam-C significantly enhanced the healing of the full-thickness skin burn wounds, although the latter was more effective, useful and practical in burn wound healing. The histopathological features of the wounds in the piracetam-C group were closer to those of the control group than those of the other groups. Piracetam-C rather than piracetam-IV may promote full-thickness burn wound healing in rabbits. © 2015 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Endoscopic full-thickness plication allows transmural suturing at the gastroesophageal junction to recreate the antireflux barrier. Multichannel intraluminal impedance monitoring (MII) can be used to detect nonacid or weakly acidic reflux, acidic swallows, and esophageal clearance time. This study used MII to evaluate the outcome of endoscopic full-thickness plication. In this study, 12 subsequent patients requiring maintenance proton pump inhibitor therapy underwent endoscopic full-thickness plication for treatment of gastroesophageal reflux disease. With patients off medication, MII was performed before and 6-months after endoscopic full-thickness plication. The total median number of reflux episodes was significantly reduced from 105 to 64 (p = 0.016). The median number of acid reflux episodes decreased from 73 to 43 (p = 0.016). Nonacid reflux episodes decreased from 23 to 21 (p = 0.306). The median bolus clearance time was 12 s before treatment and 11 s at 6 months (p = 0.798). The median acid exposure time was reduced from 6.8% to 3.4% (p = 0.008), and the DeMeester scores were reduced from 19 to 12 (p = 0.008). Endoscopic full-thickness plication significantly reduced total reflux episodes, acid reflux episodes, and total reflux exposure time. The DeMeester scores and total acid exposure time for the distal esophagus were significantly improved. No significant changes in nonacid reflux episodes and median bolus clearance time were encountered.

    Irritable bowel syndrome (IBS) manifests as chronic abdominal pain. One pathophysiological theory states that the brain-gut axis is responsible for pain control in the intestine. Although several studies have discussed the structural changes in the brain of IBS patients, most of these studies have been conducted in Western populations. Different cultures and sexes experience different pain sensations and have different pain responses. Accordingly, we aimed to identify the specific changes in the cortical thickness of Asian women with IBS and to compare these data to those of non-Asian women with IBS. Thirty Asian female IBS patients (IBS group) and 39 healthy individuals (control group) were included in this study. Brain structural magnetic resonance imaging was performed. We used FreeSurfer to analyze the differences in the cortical thickness and their correlations with patient characteristics. The left cuneus, left rostral middle frontal cortex, left supramarginal cortex, right caudal anterior cingulate cortex, and bilateral insula exhibited cortical thinning in the IBS group compared with those in the controls. Furthermore, the brain cortical thickness correlated negatively the severity as well as duration of abdominal pain. Some of our findings differ from those of Western studies. In our study, all of the significant brain regions in the IBS group exhibited cortical thinning compared with those in the controls. The differences in cortical thickness between the IBS patients and controls may provide useful information to facilitate regulating abdominal pain in IBS patients. These findings offer insights into the association of different cultures and sexes with differences in cortical thinning in patients with IBS.

    Repair of large incisional hernias includes the implantation of a synthetic mesh, but this may lead to pain, stiffness, infection and enterocutaneous fistulae. Autologous full-thickness skin graft as on-lay reinforcement has been tested in eight high-risk patients in a proof-of-concept study, with satisfactory results. In this multicenter randomized study, the use of skin graft was compared to synthetic mesh in giant ventral hernia repair. Non-smoking patients with a ventral hernia > 10 cm wide were randomized to repair using an on-lay autologous full-thickness skin graft or a synthetic mesh. The primary endpoint was surgical site complications during the first 3 months. A secondary endpoint was patient comfort. Fifty-three patients were included. Clinical evaluation was performed at a 3-month follow-up appointment. There were fewer patients in the skin graft group reporting discomfort: 3 (13%) vs. 12 (43%) (p = 0.016). Skin graft patients had less pain and a better general improvement. No difference was seen regarding seroma; 13 (54%) vs. 13 (46%), or subcutaneous wound infection; 5 (20%) vs. 7 (25%). One recurrence appeared in each group. Three patients in the skin graft group and two in the synthetic mesh group were admitted to the intensive care unit. No difference was seen for the primary endpoint short-term surgical complication. Full-thickness skin graft appears to be a reliable material for ventral hernia repair producing no more complications than when using synthetic mesh. Patients repaired with a skin graft have less subjective abdominal wall symptoms.

    The objectives of this study were to: (1) document the incidence of surgical site dehiscence after full-thickness gastrointestinal biopsy in dogs and cats and (2) identify potential risk factors. Data relating to dogs and cats undergoing full-thickness gastrointestinal biopsy were reviewed retrospectively following submission of a completed questionnaire by 12 referral institutions. Outcome measures were definite dehiscence, possible dehiscence (clinical records suggestive of dehiscence but not confirmed), suspected dehiscence (definite and possible combined) and death within 14 days. Logistic regression was planned for analysis of association of dehiscence with low preoperative serum albumin, biopsy through neoplastic tissue, biopsy alongside another major abdominal surgical procedure and biopsy of the colon. Of 172 cats, two (1·2%) had definite dehiscence, and four (2·3%) had possible dehiscence. Low preoperative serum albumin was significantly associated with definite dehiscence in univariable analysis and with suspected dehiscence and death within 14 days in univariable analysis, but all odds ratios had wide 95% confidence intervals. A histopathological diagnosis of neoplasia was significantly associated with death within 14 days in univariable analysis. Of 195 dogs, two (1·0%) had definite dehiscence, and three (1·5%) had possible dehiscence. In dogs, there was no association between any outcome measure and the putative risk factors. Incidence of dehiscence following full-thickness gastrointestinal biopsy was low in this study. When determining the appropriateness of biopsy in individual cases, this information should be balanced against the potentially life-threatening consequences of dehiscence. © 2017 British Small Animal Veterinary Association.

    A circumferential full-thickness burn to the penis is a rarely encountered injury. However, when it does occur, it proves a management challenge to the plastic and burns surgeon in terms of reconstruction. This is due to the need of not only regaining adequate function of the organ, but also because of the need for a pleasing aesthetic outcome. Split-skin grafts have been utilised successfully to resurface full thickness burns of the penis and have given good results. Yet the success of split-skin grafts, especially those applied to an anatomically challenging region of the body such as the penis, depends on a number of carefully thought-out steps. We discuss the case of a circumferential full-thickness burn to the penis which was treated with split-skin grafting and highlight important pitfalls that the plastic and burns surgeon need to be aware of to ensure a successful outcome.

  2. One-sheet spiraling full thickness skin graft for penile resurfacing after paraffinoma excision

    Directory of Open Access Journals (Sweden)

    2011-08-01

    Full Text Available In the midst of on-going non-illicit practice of silicone or paraffin injection to enlarge penis, the author reported 3 cases of surgical treatment to resurface the body of the penis after excision of the destructed penile skin using full thickness skin graft. The skin excision was performed technically through penile body degloving procedure. Full thickness skin graft was then applied as a single sheet donor tissue to cover the denuded penile body spirally. The full thickness graft, which is relatively easy to be performed, is no doubt much thinner than a skin flap, while it also bears a smaller degree of secondary contraction than split skin graft. The color of the skin is considerably matched as it comes from the groin, which is a nearby area of penis. The size and skin sensitization of the penis looks to be natural. The only disadvantage is the common possibility of either spiral or circular junctional scar in between graft edges and between the graft and the penile mucosa and skin to develop hypertrophic scar. However, this possible scar problem applies also to any other surgical scar with any donor tissue. Fortunately, the 3 cases posed no scar problem and normal appearance. All the patients have also regained their normal sexual function. (Med J Indones 2011; 20:222-5Keywords: full thickness skin graft, paraffinoma, siliconoma, sexual function

    Full Text Available Accessory auricles are relatively rare malformations arising from the first branchial arch which contains skin, fat and cartilage. The treatment is usually surgical removal for the cosmetic purpose. We are sharing our experience of utilising the accessory auricle skin as full thickness graft for post.burn reconstruction of the fingers contracture of a child. Even though this type of association is rare, it is an innovative idea following Sir Harold Gilles’ principle ‘Never throw anything away’.

    Objective: To explore a feasible method to repair full-thickness skin defects utilizing tissue engineered techniques. Methods: The Changfeng hybrid swines were used and the skin specimens were cut from the posterior limb girdle region, from which the keratinocytes and fibroblasts were isolated and harvested by trypsin, EDTA, and type II collagenase. The cells were seeded in Petri dishes for primary culture. When the cells were in logarithmic growth phase, they were treated with trypsin to separate them from the floor of the tissue culture dishes. A biodegradable material, Pluronic F-127, was prefabricated and mixed with these cells, and then the cell-Pluronic compounds were seeded evenly into a polyglycolic acid (PGA). Then the constructs were replanted to the autologous animals to repair the full-thickness skin defects. Histology and immunohistochemistry of the neotissue were observed in 1, 2, 4, and 8 postoperative weeks. Results: The cell-Pluronic F-127-PGA compounds repaired autologous full-thickness skin defects 1 week after implantation. Histologically, the tissue engineered skin was similar to the normal skin with stratified epidermis overlying a moderately thick collageneous dermis. Three of the structural proteins in the epidermal basement membrane zone, type IV collagen, laminin, and type VII collagen were detected using immunohistochemical methods. Conclusions: By studying the histology and immunohistochemistry of the neotissue, the bioengineered skin graft holds great promise for improving healing of the skin defects.

    Full Text Available Purpose. To evaluate the clinical outcomes in patients with central retinal vein occlusion (CRVO treated with full-thickness retinochoroidal incisions and to compare whether there is difference in treatment response in ischemic and nonischemic CRVO. Methods. Retrospective study of patients of CRVO receiving full-thickness retinochoroidal incisions in Changhua Christian Hospital. Fluorescein angiography (FA, slit-lamp biomicroscopy, indirect funduscopy, best corrected visual acuity, and central macular thickness (CMT measured by optical coherence tomography were performed pre- and postoperatively. Patients were divided into an ischemic and nonischemic group according to the findings of FA. Patients were followed up for at least 1 year. Results. Twenty-eight eyes (14 ischemic and 14 nonischemic CRVO were included. Functional retinochoroidal venous anastomosis (RCVA was achieved in 48 of the 65 retinochoroidal incisions (73.8%. Central macular thickness (CMT and retinal hemorrhage decreased significantly after the surgery. Significant visual gain was observed postoperatively in the nonischemic group, but not in the ischemic group. Postoperative complications included vitreous hemorrhage (17.8%, neovascular glaucoma (7.1%, and preretinal fibrovasular membrane (10.7%, all of which were in the ischemic group. Conclusions. RCVA formation induced by retinochoroidal incisions could improve venous flow, and decrease CMT and retinal hemorrhage. However, only eyes with nonischemic CRVO showed visual improvement.

    Healing of the uterus after cesarean section and myomectomy operation is clinically important. In this study, we aimed to investigate the effects of resveratrol (3,5,4'-o-trihydroxystilbene) on the wound healing process of the uterus in rats treated with resveratrol following full thickness injury of the uterus. Twenty-one female wistar albino rats were divided randomly into three groups (1) control group with no intervention (2) injury group with uterine full thickness injury (3) resveratrol group with uterine full thickness injury and treated with resveratrol. Resveratrol was injected by oral gavage at the doses of 0.5 mg/kg/day for 30 days following uterine full thickness injury. Vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) distributions were assessed using the immunohistochemical methods in tissue and ELISA methods in the tissue homogenate. Glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities were evaluated with colorimetric method and malondialdehyde (MDA) levels also were measured using high performance liquid chromatography in the tissue homogenate. The effects of resveratrol on the uterine histology also were evaluated histologically with the light microscopy. Histological evaluation and immunohistochemical evaluations showed that treatment with a resveratrol significantly increased the thickness of the uterine wall and VEGF expression and decreased expression PDGF during wound healing. Biochemically, GPx and SOD activities were increased significantly after treatment with resveratrol. Additionally, resveratrol administration decreased MDA levels. These results showed that the antioxidant effects of resveratrol has been shown to have a positive influence on wound healing of the uterus. Copyright © 2017. Published by Elsevier B.V.

    Purpose: Quantitative measurements of wall thickness in human abdominal aortic aneurysms (AAAs) may lead to more accurate methods for the evaluation of their biomechanical environment. Methods: The authors describe an algorithm for estimating wall thickness in AAAs based on intensity histograms and neural networks involving segmentation of contrast enhanced abdominal computed tomography images. The algorithm was applied to ten ruptured and ten unruptured AAA image data sets. Two vascular surgeons manually segmented the lumen, inner wall, and outer wall of each data set and a reference standard was defined as the average of their segmentations. Reproducibility was determined by comparing the reference standard to lumen contours generated automatically by the algorithm and a commercially available software package. Repeatability was assessed by comparing the lumen, outer wall, and inner wall contours, as well as wall thickness, made by the two surgeons using the algorithm. Results: There was high correspondence between automatic and manual measurements for the lumen area (r=0.978 and r=0.996 for ruptured and unruptured aneurysms, respectively) and between vascular surgeons (r=0.987 and r=0.992 for ruptured and unruptured aneurysms, respectively). The authors' automatic algorithm showed better results when compared to the reference with an average lumen error of 3.69%, which is less than half the error between the commercially available application Simpleware and the reference (7.53%). Wall thickness measurements also showed good agreement between vascular surgeons with average coefficients of variation of 10.59% (ruptured aneurysms) and 13.02% (unruptured aneurysms). Ruptured aneurysms exhibit significantly thicker walls (1.78±0.39 mm) than unruptured ones (1.48±0.22 mm), p=0.044. Conclusions: While further refinement is needed to fully automate the outer wall segmentation algorithm, these preliminary results demonstrate the method's adequate reproducibility and

    Human abdominal response and injury in blunt impacts was investigated through finite element simulations of cadaver tests using a full human body model of an average-sized adult male. The model was validated at various impact speeds by comparing model responses with available experimental cadaver test data in pendulum side impacts and frontal rigid bar impacts from various sources. Results of various abdominal impact simulations are presented in this paper. Model-predicted abdominal dynamic responses such as force-time and force-deflection characteristics, and injury severities, measured by organ pressures, for the simulated impact conditions are presented. Quantitative results such as impact forces, abdominal deflections, internal organ stresses have shown that the abdomen responded differently to left and right side impacts, especially in low speed impact. Results also indicated that the model exhibited speed sensitive response characteristics and the compressibility of the abdomen significantly influenced the overall impact response in the simulated impact conditions. This study demonstrates that the development of a validated finite element human body model can be useful for abdominal injury assessment. Internal organ injuries, which are difficult to detect in experimental studies with human cadavers due to the difficulty of instrumentation, may be more easily identified with a validated finite element model through stress-strain analysis.

    Full Text Available An acellular cholecyst derived extracellular matrix (b-CEM of bubaline origin was prepared using anionic biological detergent. Healing potential of b-CEM was compared with commercially available collagen sheet (b-CS and open wound (C in full thickness skin wounds in rats. Thirty-six clinically healthy adult Sprague Dawley rats of either sex were randomly divided into three equal groups. Under general anesthesia, a full thickness skin wound (20 × 20 mm2 was created on the dorsum of each rat. The defect in group I was kept as open wound and was taken as control. In group II, the defect was repaired with commercially available collagen sheet (b-CS. In group III, the defect was repaired with cholecyst derived extracellular matrix of bovine origin (b-CEM. Planimetry, wound contracture, and immunological and histological observations were carried out to evaluate healing process. Significantly (P<0.05 increased wound contraction was observed in b-CEM (III as compared to control (I and b-CS (II on day 21. Histologically, improved epithelization, neovascularization, fibroplasia, and best arranged collagen fibers were observed in b-CEM (III as early as on postimplantation day 21. These findings indicate that b-CEM have potential for biomedical applications for full thickness skin wound repair in rats.

    Fluorescence imaging using indocyanine green (ICG) has recently been applied to laparoscopic surgery to identify cancerous tissues, lymph nodes, and vascular anatomy. Here we report the application of ICG-fluorescence imaging to visualize the boundary between the liver and subserosal tissues of the gallbladder during laparoscopic full-thickness cholecystectomy. A patient with a potentially malignant gallbladder lesion was administered 2.5-mg intravenous ICG just before laparoscopic full-thickness cholecystectomy. Intraoperative fluorescence imaging enabled the real-time delineation of both extrahepatic bile duct anatomy and hepatic parenchyma throughout the procedure, which resulted in complete removal of subserosal tissues between liver and gallbladder. Safe and feasible ICG-fluorescence imaging can be widely applied to laparoscopic hepatobiliary surgery by utilizing a biliary excretion property of ICG. © 2014 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

    Full Text Available BackgroundPediatric hand burns are a difficult problem because they lead to serious hand deformities with functional impairment due to rapid growth during childhood. Therefore, adequate management is required beginning in the acute stage. Our study aims to establish surgical guidelines for a primary full-thickness skin graft (FTSG in pediatric hand burns, based on long-term observation periods and existing studies.MethodsFrom January 2000 to May 2011, 210 patients underwent primary FTSG. We retrospectively studied the clinical course and treatment outcomes based on the patients' medical records. The patients' demographics, age, sex, injury site of the fingers, presence of web space involvement, the incidence of postoperative late deformities, and the duration of revision were critically analyzed.ResultsThe mean age of the patients was 24.4 months (range, 8 to 94 months, consisting of 141 males and 69 females. The overall observation period was 6.9 years (range, 1 to 11 years on average. At the time of the burn, 56 cases were to a single finger, 73 to two fingers, 45 to three fingers, and 22 to more than three. Among these cases, 70 were burns that included a web space (33.3%. During the observation, 25 cases underwent corrective operations with an average period of 40.6 months.ConclusionsIn the volar area, primary full-thickness skin grafting can be a good indication for an isolated injured finger, excluding the web spaces, and injuries of less than three fingers including the web spaces. Also, in the dorsal area, full-thickness skin grafting can be a good indication. However, if the donor site is insufficient and the wound is large, split-thickness skin grafting can be considered.

    Many patients with rotator cuff tears suffer from nocturnal shoulder pain, resulting in sleep disturbance. To determine whether rotator cuff tear size correlated with sleep disturbance in patients with full-thickness rotator cuff tears. Cross-sectional study; Level of evidence, 3. Patients with a diagnosis of unilateral full-thickness rotator cuff tears (diagnosed via magnetic resonance imaging [MRI]) completed the Pittsburgh Sleep Quality Index (PSQI), a visual analog scale (VAS) quantifying their shoulder pain, and the American Shoulder and Elbow Surgeons (ASES) questionnaire. Shoulder MRI scans were analyzed for anterior-posterior tear size (mm), tendon retraction (mm), Goutallier grade (0-4), number of tendons involved (1-4), muscle atrophy (none, mild, moderate, or severe), and humeral head rise (present or absent). Bivariate correlations were calculated between the MRI characteristics and baseline survey results. A total of 209 patients with unilateral full-thickness rotator cuff tears were included in this study: 112 (54%) female and 97 (46%) male (mean age, 64.1 years). On average, shoulder pain had been present for 24 months. The mean PSQI score was 9.8, and the mean VAS score was 5.0. No significant correlations were found between any of the rotator cuff tear characteristics and sleep quality. Only tendon retraction had a significant correlation with pain. Although rotator cuff tears are frequently associated with nocturnal pain and sleep disruption, this study demonstrated that morphological characteristics of full-thickness rotator cuff tears, such as size and tendon retraction, do not correlate with sleep disturbance and have little to no correlation with pain levels.

    The purpose is to investigate the relationship between full-thickness macular hole (MH) and retinal break (RB) and/or lattice degeneration. Patients diagnosed as full-thickness MH and referred to Dr. Lin Lu from January 2009 to December 2013 were evaluated. All patients underwent general ophthalmologic examinations, fundus examination and optical coherence tomography (OCT). The RB and/or lattice degeneration were recorded. Totally 183 eyes of 167 patients were included. The sex ratio of men to women was 1:2.88. A total of 17 eyes were pseudophakic and 166 eyes were phakic. RB and/or lattice degeneration were found in 62 eyes (33.88%). The prevalence of RB and/or lattice degeneration was similar between men and women (P = 0.344 > 0.05). There was no statistical difference between the pseudophakic eyes and phakic eyes (P = 0.138 > 0.05). All of the RB and/or lattice degeneration were located near or anterior to the equator. The inferior quadrants and the vertical meridian were affected more often than the superior quadrants and the horizontal meridian. We identified a high incidence of RB/lattice degeneration in cases of full-thickness MH. Carefully examination of the peripheral retina and prophylactic treatment of RB and/or lattice degeneration are critical.

    To testify the effect of the stem cells derived from the widely distributed fat tissue on repairing full-thickness hyaline cartilage defects. Adipose-derived stem cells (ADSCs) were derived from adipose tissue and cultured in vitro. Twenty-seven New Zealand white rabbits were divided into three groups randomly. The cultured ADSCs mixed with calcium alginate gel were used to fill the full-thickness hyaline cartilage defects created at the patellafemoral joint, and the defects repaired with gel or without treatment served as control groups. After 4, 8 and 12 weeks, the reconstructed tissue was evaluated macroscopically and microscopically. Histological analysis and qualitative scoring were also performed to detect the outcome. Full thickness hyaline cartilage defects were repaired completely with ADSCs-derived tissue. The result was better in ADSCs group than the control ones. The microstructure of reconstructed tissue with ADSCs was similar to that of hyaline cartilage and contained more cells and regular matrix fibers, being better than other groups. Plenty of collagen fibers around cells could be seen under transmission electron microscopy. Statistical analysis revealed a significant difference in comparison with other groups at each time point (t equal to 4.360, P less than 0.01). These results indicate that stem cells derived from mature adipose without induction possess the ability to repair cartilage defects.

    Advances in tissue engineering led to the development of various tissue-engineered skin substitutes (TESS) for the treatment of skin injuries. The majority of the autologous TESS required lengthy and costly cell expansion process to fabricate. In this study, we determine the possibility of using a low density of human skin cells suspended in platelet-rich plasma (PRP)-enriched medium to promote the healing of full-thickness skin wounds. To achieve this, full-thickness wounds of size 1.767 cm 2 were created at the dorsum part of nude mice and treated with keratinocytes (2 × 10 4  cells/cm 2 ) and fibroblasts (3 × 10 4  cells/cm 2 ) suspended in 10% PRP-enriched medium. Wound examination was conducted weekly and the animals were euthanized after 2 weeks. Gross examination showed that re-epithelialization was fastest in the PRP+cells group at both day 7 and 14, followed by the PRP group and NT group receiving no treatment. Only the PRP+cells group achieved complete wound closure by 2 weeks. Epidermal layer was presence in the central region of the wound of the PRP+cells and PRP groups but absence in the NT group. Comparison between the PRP+cells and PRP groups showed that the PRP+cells-treated wound was more mature as indicated by the presence of thinner epidermis with single cell layer thick basal keratinocytes and less cellular dermis. In summary, the combination of low cell density and diluted PRP creates a synergistic effect which expedites the healing of full-thickness wounds. This combination has the potential to be developed as a rapid wound therapy via the direct application of freshly harvested skin cells in diluted PRP. Copyright © 2017 Tissue Viability Society.

    Full Text Available BackgroundRosa damascena, a type of herb, has been used for wound healing in Eastern folk medicine. The goal of this study was to evaluate the effectiveness of rose placenta from R. damascena in a full-thickness wound model in mice.MethodsSixty six-week-old C57BL/6N mice were used. Full-thickness wounds were made with an 8-mm diameter punch. Two wounds were made on each side of the back, and wounds were assigned randomly to the control and experimental groups. Rose placenta (250 µg was injected in the experimental group, and normal saline was injected in the control group. Wound sizes were measured with digital photography, and specimens were harvested. Immunohistochemical staining was performed to assess the expression of epidermal growth factor (EGF, vascular endothelial growth factor (VEGF, transforming growth factor-β1 (TGF-β1, and CD31. Vessel density was measured. Quantitative analysis using an enzyme-linked immunosorbent assay (ELISA for EGF was performed. All evaluations were performed on postoperative days 0, 2, 4, 7, and 10. Statistical analyses were performed using the paired t-test.Results On days 4, 7, and 10, the wounds treated with rose placenta were significantly smaller. On day 2, VEGF and EGF expression increased in the experimental group. On days 7 and 10, TGF-β1 expression decreased in the experimental group. On day 10, vessel density increased in the experimental group. The increase in EGF on day 2 was confirmed with ELISA.ConclusionsRose placenta was found to be associated with improved wound healing in a mouse full-thickness wound model via increased EGF release. Rose placenta may potentially be a novel drug candidate for enhancing wound healing.

    This report describes a model organ-culture system for testing the toxicity of chemical substances that are topically applied to human skin. In this system, the viable keratinocytes in the full-thickness skin explants are protected by the same keratinized layer as skin remaining on the donor, and toxicity can be assessed microscopically and/or biochemically. The human skin specimens were discards from a variety of surgical procedures. They were cut into full-thickness 1.0-cm2 explants, and briefly exposed to the military vesicant sulfur mustard (SM), which was used as a model toxicant. The explants were then organ cultured in small Petri dishes for 24 h at 36 degrees C. In the 0.03-1.0% dosage range, a straight-line dose-response relationship occurred between the concentration of SM applied and the number of paranuclear vacuoles seen histologically in the epidermis. Within the same SM dosage range, there was also a proportional decrease in 14C-leucine incorporation by the explants. Thus, the number of paranuclear vacuoles reflected decreases in protein synthesis by the injured epidermal cells. The epidermis of full-thickness untreated (control) human skin explants usually remained viable for 7 d when stored at 4 degrees C in culture medium. During storage, a relatively small number of paranuclear vacuoles developed within the epidermis, but the explants were still quite satisfactory for testing SM toxicity. Incubation (for 4 or 24 h at 36 degrees C) of such control skin explants reduced (often by 50%) the small number of paranuclear vacuoles produced during 4-7 d of storage. This reduction was probably caused by autolysis of many of the vacuolated cells. Two types of paranuclear vacuoles could be identified by both light and electron microscopy: a storage type and a toxicant type. The storage type seemed to be caused by autolysis of cell components

    An acceleration of the wound healing process expedites chronic wound patient's return to normal social environments significantly. Sildenafil, a cyclic guanosine monophosphate (cGMP)-dependent phosphodiesterase- 5 inhibitor has been shown to be a potent stimulator of angiogenesis through upregulation of cGMP. In our study, sildenafil was administered orally as a cost-effective supplement in the treatment of full thickness defects and chronic wounds in that manner with low incidence of side effects and morbidity. Randomly selected 72 Wistar-Albino rats were divided into the two groups, 36 rats in each group. Control group (n =36) was divided further into a secondary healing group consisting of 9 rats and a pathology group consisting of 27 rats (pathology group 1: 9 rats, 4th and 7th day of wound healing, pathology group 2: 9 rats, 10th and 14th day of wound healing, pathology group 3: 9 rats, 21st and 28th day of wound healing. Experimental group consisted of 36 rats which received sildenafil citrate (Viagra® Pfizer, Germany) for secondary wound healing to proceed. The average wound healing period in the control group was 17.89 days and in the sildenafil citrate administered group 14.56 days. The difference of the epithelialisation on full thickness defects were more prominent on days 5 and 11 postoperatively. In the sildenafil citrate applied group, on the 7th day, the defect was 25% smaller and on the 13th day, the defect contracted by 38%. In conclusion, we believe that sildenafil citrate administered orally is a cost- effective supplement in the treatment of full thickness defects and chronic wounds in that manner with low incidence of side effects and morbidity (Tab. 4, Fig. 7, Ref. 34).

    Aim: To assess the relationship between the severity of full-thickness supraspinatus tendon tears and the development of subcoracoid impingement. Materials and methods: Fifty-one magnetic resonance imaging (MRI) shoulder examination reports with full-thickness supraspinatus tears were retrospectively identified and reviewed by two dedicated musculoskeletal radiologists. The appearances of the rotator cuff muscles, biceps tendon and the lesser tubercle were recorded. The acromio-humeral distance and the axial coraco-humeral distance were measured. The data were recorded and analysed electronically. Results: The kappa values for inter-observer agreement were: 0.91 for acromio-humeral distance and 0.85 for coraco-humeral distance measurements. Twenty-six patients had significant retraction of the supraspinatus tendon, 85% (22 cases) of this group had imaging evidence of tear or tendonopathy of the subscapularis tendon. Twenty-five patients had no significant retraction of the supraspinatus, 56% (14 cases) of this group had imaging evidence of a subscapularis tear or tendonopathy. The acromio-humeral distance was significantly less in patients with supraspinatus tears and retraction (p < 0.05). The subscapularis tendon was significantly more likely to be abnormal if the supraspinatus was retracted than if no retraction was present (p < 0.05). There were no significant differences in coraco-humeral distances between the groups. Conclusion: Subscapularis tendon signal and structural changes are frequently associated with full-thickness supraspinatus tendon tears, particularly if the supraspinatus is significantly retracted. In this static MRI series, the data do not support the occurrence of classical subcoracoid impingement as an aetiology; however, they may support the possibility of a dynamic mechanism, to which future studies could be directed.

    Full Text Available Background: Rotator cuff tendon tear injury is one of the most frequently seen orthopaedic conditions, and surgical repair of rotator cuff tears is a common procedure. The purpose of the present study was to determine the results of full-thickness rotator cuff repair and to look for predictors of outcomes. Methods: we studied 27 patients (17 men and 10 women with a mean age of 57.7 years who underwent open rotator cuff repair surgery for full-thickness tear between 2001 and 2005 at the Imam Khomeini Hospital and were subsequently followed-up for 6 and 12 months after surgery. The shoulder function was assessed by Constant classification and factors potentially associated with outcomes were Results: The mean of preoperative Constant score (CS was 45.8 ± 14.1 after 12 months, 6 patients (22.2% had good results and 21 patients (77.8% had excellent result according to CS. Pain relief was generally satisfactory. Using multiple regression analysis, treatment was significantly correlated preoperative CS and acromio-humeral interval (AHI however, no correlation was found between the result of the treatment and pretreatment atrophy, tear size, acromial morphology, preoperative symptom duration and age. Conclusion: In this study, a standard rotator cuff repair technique reduced pain severity and was associated with good results, however larger studies are necessary to define the long-term outcome of this procedure.

    To explore a reconstruction method for complete nail bed defect caused by various kinds of reasons and to retrospectively analyze the effect of application of free full-thickness skin graft for the whole nail unit repair. Between Apr. 2010 and Mar. 2012, the method of free full-thickness skin graft was done for reconstruction of the completely nail unit defect in seven cases. There were 2 male and 5 female patients; the mean age of these patients at the time of surgery was 51.9 years (range: 7 to 70 years). The preoperative diagnoses included two cases of malignant melanoma, one of chronic infection, one of squamous cell carcinoma, two of subungual pigmentation and one of junctional nevus. There were 2 thumb lesions, 3 middle and 2 index finger lesions. Nail unit defect was in the range of 1.5 cm×2 cm to 2.5 cm × 3.5 cm and full thickness skin graft was harvested from the same medial side of upper arm (3 cases), forearm cubital fossa (1 case) and contralateral side of groin region (3 cases). All the patients were followed with an average follow-up time being 10 months. All the free skin graft taken was achieved with 100% in all the 7 cases, even in those patients whose partial cortical bone had been curetted. The skin graft was often bluish initially, and superficial blisters were always noticed within 1.5 months postoperatively and the survival skin graft was smooth eventually, and skin graft was adhered to the underlying bone tightly. There was no epidermal inclusion cyst and no residual nail formation. The skin donor sites were without complications. Aesthetic appearance was assessed by the surgeons and found no unacceptable for their patients. And all the patients were satisfied with the cosmetic appearance and active range of motion of their involved fingers, who did not express a desire to undergo any further of nail reconstruction. Free full-thickness skin grafting for reconstruction of the complete nail unit defect is a simple, safe and effective

    Full thickness skin graft (FTSG) gives better outcomes than split thickness skin graft (STSG), but it has the drawback of limited donor sites. Anterolateral thigh (ALT), a popular donor site of STSG, is also a popular donor site of perforator flaps. This area has the advantage of large flap size available with primary closure. Based on this we harvested FTSG instead of STSG from the ALT. We retrospectively reviewed 10 cases of FTSG from the ALT, with the recipient site of foot in 3, ankle in 2, lower leg in 2, forearm in 2, and wrist in 1 patient. In all cases elliptical full thickness skin was harvested from the ALT, and the donor site was closed primarily. The skin was defatted and placed onto the defect with vacuum-assisted closure (VAC). The skin size ranged 7-30 cm in length and 3-12 cm in width. Mean follow up period was 7 months (range, 3-13). FTSG from the ALT provided durable wound coverage, with excellent color and texture matching. Partial (< 20%) graft failure was observed in 1 case, but no additional surgery was necessary. No patient reported donor site pain at postoperative 2 weeks. No donor site complications were encountered. No patient complained a feeling of tension in the thigh at final follow-up. FTSG from the ALT is feasible with the aid of VAC. Considering the skin quality, large skin size available, early pain relief, and little donor site morbidity, the ALT should be revisited as a donor site of FTSG.

    Cryptotia is a common congenital ear deformity in Asian populations. In cryptotia, a portion of the upper ear is hidden and fixed in a pocket of the skin of the mastoid. Here we describe our method for cryptotia correction by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap. We developed a new method for correcting cryptotia by using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap. Following ear release, the full-thickness skin rotation flap is rotated into the defect, and the donor site is covered with an ultra-delicate split-thickness skin graft raised in continuity with the flap. All patients exhibited satisfactory release of cryptotia. No cases involved partial or total flap necrosis, and post-operative outcomes using this new technique for cryptotia correction have been more than satisfactory. Our method of using an ultra-delicate split-thickness skin graft in continuity with a full-thickness skin rotation flap to correct cryptotia is simple and reliable.

    The healing failure rate is high for partial-thickness or small full-thickness rotator cuff tears. To retrospectively evaluate and compare outcomes after arthroscopic repair of high-grade partial-thickness and small full-thickness rotator cuff tears and factors affecting rotator cuff healing. Cohort study; Level of evidence, 3. Included in the study were 55 consecutive patients (mean age, 57.9 ± 7.2 years) who underwent arthroscopic repair for high-grade partial-thickness (n = 34) and small full-thickness (n = 21) rotator cuff tears. The study patients also underwent magnetic resonance imaging (MRI) preoperatively and computed tomography arthrography (CTA) at least 6 months postoperatively, and their functional outcomes were evaluated preoperatively and at the last follow-up (>24 months). All partial-thickness tears were repaired after being converted to full-thickness tears; thus, the repair process was almost the same as for small full-thickness tears. The tendinosis of the torn tendon was graded from the MRI images using a 4-point scale, and the reliabilities were assessed. The outcomes between high-grade partial-thickness tears that were converted to small full-thickness tears and initially small full-thickness tears were compared, and factors affecting outcomes were evaluated. The inter- and intraobserver reliabilities of the tendinosis grade were good (intraclass correlation coefficient, 0.706 and 0.777, respectively). Failure to heal as determined by CTA was observed in 12 patients with a high-grade partial-thickness tear (35.3%; complete failure in 4 and partial failure in 8) and in 3 patients with a small full-thickness tear (14.3%; complete failure in 1 and partial failure in 2). The patients with high-grade partial-thickness rotator cuff tears showed a higher tendinosis grade than did those with small full-thickness tears (P = .014), and the severity of the tendinosis was related to the failure to heal (P = .037). Tears with a higher tendinosis grade

    Many studies have been conducted on the treatment of burns because they are important in morbidity and mortality. These studies are mainly focused on improving care and quality of life of patients. The aim of this study was evaluate the LED phototherapy effects in rats skin full-thickness burns induced by CO 2 laser. The animals were divided in NT group that did not received any treatment and LED group that received LED irradiation at 685 nm, 220 mW, and 4.5 J/cm 2 during 40 s by burned area. Biopsies were obtained after 7, 14, and 21 days of treatment and submitted to histological and immunohistochemical analysis. The LED phototherapy shows anti-inflammatory effects, improves angiogenesis, and stimulates the migration and proliferation of fibroblasts. The T CD8+ lymphocytes were more common in burned areas compared to T CD4+ lymphocytes since statistically significant differences were observed in the LED group compared to the NT group after 7 days of treatment. These results showed that LED phototherapy performs positive influence in full-thickness burns repair from the healing process modulated by cellular immune response. The obtained results allowed inferring that burns exhibit a characteristic cell immune response and this cannot be extrapolated to other wounds such as incision and wounds induced by punch, among others.

    Engineered skin substitutes (ESSs) have been reported to close full-thickness burn wounds but are subject to loss from mechanical shear due to their deficiencies in tensile strength and elasticity. Hypothetically, if the mechanical properties of ESS matched those of native skin, losses due to shear or fracture could be reduced. To consider modifications of the composition of ESS to improve homology with native skin, biomechanical analyses of the current composition of ESS were performed. ESSs consist of a degradable biopolymer scaffold of type I collagen and chondroitin-sulfate (CGS) that is populated sequentially with cultured human dermal fibroblasts (hF) and epidermal keratinocytes (hK). In the current study, the hydrated biopolymer scaffold (CGS), the scaffold populated with hF dermal skin substitute (DSS), or the complete ESS were evaluated mechanically for linear stiffness (N/mm), ultimate tensile load at failure (N), maximum extension at failure (mm), and energy absorbed up to the point of failure (N-mm). These biomechanical end points were also used to evaluate ESS at six weeks after grafting to full-thickness skin wounds in athymic mice and compared to murine autograft or excised murine skin. The data showed statistically significant differences (p clinical morbidity from graft loss.

    Cartilage defect repair by hydrogel-based tissue engineering is becoming one of the most potential treatment strategies. In this work, a thermogel of triblock copolymer poly(lactide-co-glycolide)-block-poly(ethylene glycol)-block-poly(lactide-co-glycolide) (PLGA-PEG-PLGA) was prepared as scaffold of bone marrow mesenchymal stem cells (BMMSCs) for repair of full-thickness articular cartilage defect. At first, the copolymer solution showed a reversible sol-gel transition at physiological temperature range, and the mechanical properties of such thermogel were high enough to support the repair of cartilage. Additionally, excellent biodegradability and biocompatibility of the thermogel were demonstrated. By implanting the BMMSC-encapsulated thermogel into the full-thickness articular cartilage defect (5.0 mm in diameter and 4.0 mm in depth) in the rabbit, it was found that the regenerated cartilage integrated well with the surrounding normal cartilage and subchondral bone at 12 weeks post-surgery. The upregulated expression of glycosaminoglycan and type II collagen in the repaired cartilage, and the comparable biomechanical properties with normal cartilage suggested that the cell-encapsulated PLGA-PEG-PLGA thermogel had great potential in serving as the promising scaffold for cartilage regeneration.

    Directory of Open Access Journals (Sweden)

    Guilherme Lang Motta

    Full Text Available ABSTRACT Introduction: The ideal vaginoplasty method should promote good cosmetic and functional results with low morbidity. We describe a new technique for congenital vaginal agenesis using a full-thickness perforated skin graft. Materials and Methods: We report an 18 year old patient with vaginal agenesis (Morris syndrome that undergone a modified version of McIndoe vaginoplasty. Patient is set in a low lithotomy position and lateral traction sutures are placed in labia and a 16Fr urethral catheter inserted. An inverted “V”-shaped incision is made in the mucosal plaque below the urethra. Blunt dissection in a cephalic posterior direction forms a space between the rectum and urethra. Special care is taken to avoid rectal tear during this maneuver. A full-thickness skin graft is removed from the lower abdomen measuring 12.0×6.0cm as an aesthetic abdominoplasty. The fat tissue is removed, remaining epidermis and dermis and the graft is perforated, allowing a great surface increase. After suturing over a mold, the graft is fixed in the created space. The donor site is closed with intradermal transversal suture. Results: From January 2009 to August 2015, seven patients diagnosed with vaginal agenesis underwent this technique. There were no major complications or need for blood transfusions. At the six-month follow-up, all patients reported satisfactory sexual intercourse. There were no significant complications at donor site or neovagina that needed surgical intervention. Conclusion: Vaginal reconstruction using the perforated graft is viable with excellent functional results. Applying this modification, we yielded the good results of a classic McIndoe technique with lower donor site morbidity.

    The endoscopic full-thickness Plicator device was initially developed to provide an endoscopic treatment option for patients with GERD. Because the endoscopic full-thickness Plicator enables rapid and easy placement of transmural sutures, comparable with surgical sutures, we used the Plicator device for endoscopic treatment or prevention of GI-wall defects. To describe the outcomes and complications of endoscopic full-thickness suturing during EMR and for the treatment of gastric-wall defects. A report of 4 cases treated with the endoscopic full-thickness suturing between June 2006 and April 2007. A large tertiary-referral center. Four subjects received endoscopic full-thickness suturing. The subjects were women, with a mean age of 67 years. Of the 4 subjects, 3 received endoscopic full-thickness suturing during or after an EMR. One subject received endoscopic full-thickness suturing for treatment of a fistula. Primary outcome measurements were clinical procedural success and procedure-related adverse events. The mean time for endoscopic full-thickness suturing was 15 minutes. In all cases, GI-wall patency was restored or ensured, and no procedure-related complications occurred. All subjects responded well to endoscopic full-thickness suturing. The resection of one GI stromal tumor was incomplete. Because of the Plicator's 60F distal-end diameter, endoscopic full-thickness suturing could only be performed with the patient under midazolam and propofol sedation. The durable Plicator suture might compromise the endoscopic follow-up after EMR. The endoscopic full-thickness Plicator permits rapid and easy placement of transmural sutures and seems to be a safe and effective alternative to surgical intervention to restore GI-wall defects or to ensure GI-wall patency during EMR procedures.

    Recently revised OECD Testing Guidelines highlight the importance of considering the first site-of-contact when investigating the genotoxic hazard. Thus far, only in vivo approaches are available to address the dermal route of exposure. The 3D Skin Comet and Reconstructed Skin Micronucleus (RSMN) assays intend to close this gap in the in vitro genotoxicity toolbox by investigating DNA damage after topical application. This represents the most relevant route of exposure for a variety of compounds found in household products, cosmetics, and industrial chemicals. The comet assay methodology is able to detect both chromosomal damage and DNA lesions that may give rise to gene mutations, thereby complementing the RSMN which detects only chromosomal damage. Here, the comet assay was adapted to two reconstructed full thickness human skin models: the EpiDerm™- and Phenion ® Full-Thickness Skin Models. First, tissue-specific protocols for the isolation of single cells and the general comet assay were transferred to European and US-American laboratories. After establishment of the assay, the protocol was then further optimized with appropriate cytotoxicity measurements and the use of aphidicolin, a DNA repair inhibitor, to improve the assay's sensitivity. In the first phase of an ongoing validation study eight chemicals were tested in three laboratories each using the Phenion ® Full-Thickness Skin Model, informing several validation modules. Ultimately, the 3D Skin Comet assay demonstrated a high predictive capacity and good intra- and inter-laboratory reproducibility with four laboratories reaching a 100% predictivity and the fifth yielding 70%. The data are intended to demonstrate the use of the 3D Skin Comet assay as a new in vitro tool for following up on positive findings from the standard in vitro genotoxicity test battery for dermally applied chemicals, ultimately helping to drive the regulatory acceptance of the assay. To expand the database, the validation will

    Subscapularis tendon tears are a well-established cause of shoulder pain. The objective of the current study was to evaluate the associated shoulder pathology in patients with full-thickness subscapularis tendon tears using magnetic resonance imaging. Forty-seven magnetic resonance imaging studies taken between 2008 and 2009 with a diagnosis of full-thickness subscapularis tendon tears were reviewed. The size of the subscapularis tendon tear, amount of muscle volume loss, Goutallier grade, biceps tendon pathology, coracohumeral distance, and associated rotator cuff tears were recorded. Statistical analysis was performed. Patients 55 years and older vs those 54 years and younger had an average subscapularis tear size of 35 vs 19 mm, an average Goutallier grade of 2.7 vs 0.8, and a total muscle volume loss of 25% vs 5%, respectively. Patients with a dislocated vs normal biceps tendons had an average subscapularis tear size of 37 vs 23 mm, an average Goutallier grade of 3 vs 0.9, and a total muscle volume loss of 28% vs 7%, respectively. Patients with vs without concomitant rotator cuff tears had an average subscapularis tear size of 32 vs 17 mm, an average Goutallier grade of 2.3 vs 0.6, and a total muscle volume loss of 21% vs 3%, respectively. Overall average coracohumeral distance measured in the axial plane was 10.8±4.6 mm. Average coracaohumeral distance was 14.8 vs 8.1 mm in patients with a Goutallier grade of 0 vs 3 or 4, resepectively, and 13.6 vs 8.5 mm in patients with no rotator cuff tear vs those with a supra- and infraspinatus tear, respectively. Increased age, dislocated biceps tendons, and concomitant rotator cuff tears in patients with full-thickness subscapularis tendon tears are associated with larger subscapularis tendon tear size, higher Goutallier grades, and increased subscapularis muscle volume loss. Decreased coracohumeral distance is associated with a higher Goutallier grade and rotator cuff tears. Copyright 2013, SLACK Incorporated.

    Full Text Available Background For patients with full thickness skin defects, autologous Split-thickness skin grafts (STSG are generally regarded as the mainstay of treatment. However, skin grafts have some limitations, including undesirable outcomes resulting from scars, poor elasticity, and limitations in joint movement due to contractures. In this study, we present outcomes of Matriderm grafts used for various skin tissue defects whether it improves on these drawbacks. Methods From January 2010 to March 2012, a retrospective review of patients who had undergone autologous STSG with Matriderm was performed. We assessed graft survival to evaluate the effectiveness of Matriderm. We also evaluated skin quality using a Cutometer, Corneometer, Tewameter, or Mexameter, approximately 12 months after surgery. Results A total of 31 patients underwent STSG with Matriderm during the study period. The success rate of skin grafting was 96.7%. The elasticity value of the portion on which Matriderm was applied was 0.765 (range, 0.635-0.800, the value of the trans-epidermal water loss (TEWL was 10.0 (range, 8.15-11.00 g/hr/m2, and the humidification value was 24.0 (range, 15.5-30.0. The levels of erythema and melanin were 352.0 arbitrary unit (AU (range, 299.25-402.75 AU and 211.0 AU (range, 158.25-297.00 AU, respectively. When comparing the values of elasticity and TEWL of the skin treated with Matriderm to the values of the surrounding skin, there was no statistically significant difference between the groups. Conclusions The results of this study demonstrate that a dermal substitute (Matriderm with STSG was adopted stably and with minimal complications. Furthermore, comparing Matriderm grafted skin to normal skin using Cutometer, Matriderm proved valuable in restoring skin elasticity and the skin barrier.

    A case report describes unilateral complete laminar erosion of the caudal thoracic spine and late-presenting infection in a patient 10 years after anteroposterior reconstruction for scoliosis. To present an unusual but significant complication that may occur after implantation of spinal instrumentation. The reported patient presented with a deep infection and persistent back pain 10 years after successful anteroposterior reconstruction for adult idiopathic scoliosis. Delayed onset infections after implantation of spinal instrumentation are infrequent, yet when present, often require hardware removal. The case of a 51-year-old woman who underwent irrigation and debridement for a late-presenting infection and removal of posterior hardware 10 years after her index procedure is presented. Interoperatively, it was noted that full-thickness laminar erosion was present from T4 to T12. The patient was taken to the operating room for wound irrigation, debridement, and hardware removal. It was discovered that a Cotrel-Dubousset rod placed on the convexity of the curve had completely eroded through the lamina of T7-T12. Infectious material was found along the entire length of both the convex and concave Cotrel-Dubousset rods. Intraoperative cultures grew Staphylococcus epidermidis and Propionibacterium acnes. Intravenous and oral antibiotics were administered, resulting in resolution of the infection and preoperative pain. The exact role of late-presenting infection with regard to the laminar erosion and rod migration seen in this case remains to be elucidated. However, the authors believe the primary cause of bony erosion was mechanical in origin. Regardless, most spine surgeons will treat many patients who have had posterior spinal implants and will perform hardware removal on a significant number of these patients during their careers. A full-thickness laminar erosion exposes the spinal cord to traumatic injury during hardware removal and debridement. This case is

    Adiponectin (AdipoN), brain-derived nerotrophic factor (BDNF) and leptin (LeP) are mainly secreted from adipose tissue and are known to be involved in regulation of the development of obese. However, there are not many studies on the association between abdominal fat and neuropeptides such as AdipoN, BDNF and LeP. The aim of this study was undertaken to investigate the association between abdominal fat thickness, neuropeptides and cardiovascular disease (CVD) risk factors. The participants in the study were 138 male employees without CVD. This study was approved by the Institutional Review Board of Occupational Safety and Health Research Institute. Written informed consent for the participants in this study was obtained from all individuals. We obtained subcutaneous fat thickness (SFT) and visceral fat thickness (VFT) by using ultrasonography and neuropeptides levels were measured with ELISA kit according to the method suggested by kit manufacturer. The mean SFT and VFT were 1.58±0.51 and 4.52±1.44 cm. The mean concentrations of AdipoN, BDNF and LeP were 3.14±3.52 ng/ml, 24.11+8.52 pg/ml and 4.27±2.38 ng/ml, respectively. VFT were positively correlated with total cholesterol (r=0.217, p<0.05), LDL-cholesterol (r=0.271, p<0.01), triglyceride (r=0.233, p<0.05) and insulin (r=0.338, p<0.01), but was inversely correlated with HDL- cholesterol (r=-420, p<0.01). AdipoN levels were positively correlated with HDL-cholesterol (r=0.220, p<0.05) and were inversely correlated with total cholesterol (r=-0.196, p<0.05), LDL-cholesterol (r=-0.190, p<0.05), triglyceride (r=-0.199, p<0.05), SFT (r=-0.195, p<0.05) and VFT (r=-0.412, p<0.01). However, LeP levels showed a reverse trend to AdipoN. AdipoN level was significantly higher in non-obese participants (BMI<25 kg/m), but LeP concentration was significantly higher in obese participants (BMI>25 kg/m) than in non-obese. On multiple logistic regression analysis, obese were significantly associated with AdipoN (odds ratio=0

    Comparison of cultured skin substitutes (CSS) and split-thickness skin autograft (AG) was performed to assess whether donor-site harvesting can be reduced quantitatively and whether functional and cosmetic outcome is similar qualitatively in the treatment of patients with massive cutaneous burns. Cultured skin substitutes consisting of collagen-glycosaminoglycan substrates populated with autologous fibroblasts and keratinocytes have been shown to close full-thickness skin wounds in preclinical and clinical studies with acceptable functional and cosmetic results. Qualitative outcome was compared between CSS and AG in 45 patients on an ordinal scale (0, worst; 10, best) with primary analyses at postoperative day 28 and after about 1 year for erythema, pigmentation, pliability, raised scar, epithelial blistering, and surface texture. In the latest 12 of the 45 patients, tracings were performed of donor skin biopsies and wounds treated with CSS at postoperative days 14 and 28 to calculate percentage engraftment, the ratio of closed wound:donor skin areas, and the percentage of total body surface area closed with CSS. Measures of qualitative outcome of CSS or AG were not different statistically at 1 year after grafting. Engraftment at postoperative day 14 exceeded 75% in the 12 patients evaluated. The ratio of closed wound:donor skin areas for CSS at postoperative day 28 was significantly greater than for conventional 4:1 meshed autografts. The percentage of total body surface area closed with CSS at postoperative day 28 was significantly less than with AG. The requirement for harvesting of donor skin for CSS was less than for conventional skin autografts. These results suggest that acute-phase recovery of patients with extensive burns is facilitated and that complications are reduced by the use of CSS together with conventional skin grafting.

  8. One-stage Pelnac Reconstruction in Full-thickness Skin Defects with Bone or Tendon Exposure

    Full Text Available Summary:. Dermal regeneration template, such as Integra and Pelnac, was originally designed for treating large area burn injury by inducing regeneration of dermis. To date, it has been widely applied in various acute and chronic wound sites. The present study demonstrated that application of artificial dermis alone induced 1-stage wound healing for wounds with bone or tendon exposure that should usually be repaired by flap surgery. Eight patients who presented with skin defects with bone and/or tendon exposure were treated by 1-stage Pelnac approach. All wounds healed within 20 weeks without skin graft or flap surgery. The wound area was reconstructed by nearly normal skin structure and linear scar. In the case of scalp defect, evidence of hair follicle cell migration and regeneration during healing process was observed. Thereby, the 1-stage Pelnac reconstitution can be considered as a novel method for inducing regrowth of epidermis and hair follicles to cure large full-thickness skin defect with bone and tendon exposure in 1 stage.

    The purpose of this study was to investigate the relationship between abdominal subcutaneous fat thickness(ASFT) and maternal gestational diabetes mellitus(GDM) measured by ultrasound at period of pregnancy. We compared maternal age, pre-pregnancy body mass index, and weight gain during pregnancy in 286 pregnant women who were diagnosed with early pregnancy ASFT and high GDM screening test(50 g OGTT) of more than 140 mg/dL. ROC curve analysis was used to determine the cut-off value of ASFT for GDM prediction. Maternal age and weight gain during pregnancy were not related to GDM in the mid-trimester and pre-pregnancy body mass index and early pregnancy ASFT were significantly different between normal and GDM high risk groups. The cut-off value of ASFT for GDM prediction was 2.23 cm(AUC 0.913. Sensitivity 76.19%, Specificity 93.72%). ASFT measured by ultrasound in early pregnancy was useful as an important index for predicting mid-trimester GDM prediction. Therefore, ASFT can be used as an auxiliary diagnostic index for early recognition of GDM.

    To investigate the effects of abdominal obesity (AO) and nonalcoholic fatty liver disease (NAFLD) with or without AO on carotid arteries by determining carotid intima-media thickness (CIMT). A total of 2745 Chinese Han adults (aged between 40 and 50 years old) were recruited and divided into 4 groups: (1) NW-no NAFL group: the normal body weight without NAFLD (n = 1888); (2) AO-no NAFL group: AO without NAFLD (n = 259); (3) NW-with NAFL group: NAFLD without AO (n = 93); and (4) AO-with NAFL group: AO with NAFLD (n = 505). The CIMT rate of each group was compared among 4 groups and the regression analysis was further used to correct confounders. We found that the NW-with NAFL group had a significantly higher CIMT rate than the AO-no NAFL group ([.87 ± .31] versus [.72 ± .29] P < .01) and the AO-with NAFL group ([.87 ± .31] versus [.79 ± .26], P < .01). The ectopic liver fat accumulation may increase the risk of atherosclerosis. Therefore, screening NAFLD in the population with normal weight may be beneficial for the prevention of atherosclerosis at an early stage. Copyright © 2018 National Stroke Association.

    2010-01-01

    A novel bidirectional thickness profilometer based on transmission densitometry was designed to measure the localized thickness of semitransparent films on a dynamic manufacturing line. The densitometer model shows that, for materials with extinction coefficients between 0.3 and 2.9 D/mm, 100-500 μm measurements can be recorded with less than ±5% error at more than 10,000 locations in real time. As a demonstration application, the thickness profiles of 75 mmx100 mm regions of polymer electrolyte membrane (PEM) were determined by converting the optical density of the sample to thickness with the Beer-Lambert law. The PEM extinction coefficient was determined to be 1.4 D/mm, with an average thickness error of 4.7%.

    Wound healing is a complex process in which a sequence of interrelated phases contributes to a reduction in wound size. For diabetic patients, many of these processes are compromised, so that wound healing slows down. In this paper we present a simple ordinary differential equation model for wound healing in which attention focusses on the dominant processes that contribute to closure of a full thickness wound. Asymptotic analysis of the resulting model reveals that normal healing occurs in stages: the initial and rapid elastic recoil of the wound is followed by a longer proliferative phase during which growth in the dermis dominates healing. At longer times, fibroblasts exert contractile forces on the dermal tissue, the resulting tension stimulating further dermal tissue growth and enhancing wound closure. By fitting the model to experimental data we find that the major difference between normal and diabetic healing is a marked reduction in the rate of dermal tissue growth for diabetic patients. The model is used to estimate the breakdown of dermal healing into two processes: tissue growth and contraction, the proportions of which provide information about the quality of the healed wound. We show further that increasing dermal tissue growth in the diabetic wound produces closure times similar to those associated with normal healing and we discuss the clinical implications of this hypothesised treatment.

    To report the clinical findings and surgical outcomes of lamellar macular holes (LMH) with or without lamellar hole-associated epiretinal proliferation (LHEP), and those of full-thickness macular holes (FTMH) presenting with LHEP. From 2009 to 2013, consecutive cases of surgically treated LMH, and all FTMH cases with LHEP were reviewed, given a follow-up time over 1 year. In the LMH group (43 cases), those with LHEP (19 cases) had significantly thinner bases and larger openings than those without (24 cases). The rate of disrupted IS/OS line was higher in the LHEP subgroup preoperatively (68.4 % vs 37.5 %), but similar between subgroups postoperatively (36.8 % and 33.3 %). The preoperative and postoperative visual acuity showed no significant difference between two subgroups. In the FTMH group (13 cases), the average hole size was 219.2 ± 92.1 μm. Permanent or transient spontaneous hole closure was noted in 69.2 % of cases. An intact IS-OS line was found in only 23 % of cases at the final follow-up. In the LMH group, LHEP was associated with a more severe defect but didn't affect surgical outcomes. In the FTMH group, spontaneous hole closure was frequently noted. Despite small holes, disruption of IS-OS line was common after hole closure.

    A testing program is described that utilizes full-thickness clad beam specimens to quantify fracture toughness for shallow cracks in weld material for which metallurgical conditions are prototypic of those found in reactor pressure vessels (RPVs). The beam specimens are fabricated from an RPV shell segment that includes weld, plate and clad material. Metallurgical factors potentially influencing fracture toughness for shallow cracks in the beam specimens include material gradients and material inhomogeneities in welded regions. The shallow-crack clad beam specimens showed a significant loss of constraint similar to that of other shallow-crack single-edge notch bend (SENB) specimens. The stress-based Dodds-Anderson scaling model appears to be effective in adjusting the test data to account for in-plane loss of constraint for uniaxially tested beams, but cannot predict the observed effects of out-of-plane biaxial loading on shallow-crack fracture toughness. A strain-based dual-parameter fracture toughness correlation (based on plastic zone width) performed acceptably when applied to the uniaxial and biaxial shallow-crack fracture toughness data

    Fracture analysis was applied to full-thickness clad beam specimens containing shallow cracks in material for which metallurgical conditions are prototypic of those found in reactor pressure vessels (RPV) at beginning of life. The beam specimens were fabricated from a section of an RPV wall (removed from a canceled nuclear plant) that includes weld, plate, and clad material. Metallurgical factors potentially influencing fracture toughness for shallow cracks in the beam specimens include gradients of material properties and residual stresses due to welding and cladding applications. Fracture toughness estimates were obtained from load vs load-line displacement and load vs crack-mouth-opening displacement data using finite-element methods and estimation schemes based on the η-factor method. One of the beams experienced a significant amount of precleavage stable ductile tearing. Effects of precleavage tearing on estimates of fracture toughness were investigated using continuum damage models. Fracture toughness results from the clad beam specimens were compared with other deep- and shallow-crack single-edge notch bend (SENB) data generated previously from A533 Grade B plate material. Range of scatter for the clad beam data is consistent with that from the laboratory-scale SENB specimens tested at the same temperature

    A testing program is described that will utilize full-thickness clad beam specimens to quantify fracture toughness for shallow flaws in material for which metallurgical conditions are prototypic of those found in reactor pressure vessels (RPVs). The beam specimens are fabricated from a section of an RPV wall that includes weld, plate and clad material. Metallurgical factors potentially influencing fracture toughness for shallow flaws in the beam specimen include material gradients due to welding and cladding applications, as well as material inhomogeneities in welded regions due to reheating in multiple weld passes. Fracture toughness tests focusing on shallow flaws in plate and weld material will also provide data for evaluating the relative influence of absolute and normalized crack depth on constraint conditions. Pretest finite-element analyses are described that provide near-tip stress and strain fields for characterization of constraint in the shallow-crack specimens in terms of the Q-stress. Analysis results predict a constraint loss in the shallow-crack clad beam specimen similar to that determined for a previously tested shallow-crack single-edge notch homogeneous bend specimen with the same normalized crack depth

    Burns result in substantial morbidity because of fibroblast proliferation and contracture. Mitomycin C is a chemotherapeutic agent known to suppress fibroblast proliferation. It is used in ophthalmologic disorders and reduces scarring in upper aerodigestive surgery. No study of the effect of mitomycin C on cutaneous burns has been performed. This study examined burn healing in the presence of topical mitomycin C by evaluation of wound appearance, contraction, and histology in a pig model. Standardized full-thickness burns were produced on the flanks of three pigs. One animal received no further therapy and was an external control. Two animals underwent placement of topical mitomycin C, 0.4 mg/ml, on selected burn sites for 5 minutes. This was repeated 2 and 4 weeks after injury. Evaluation was performed at 2 and 6 months using a clinical assessment scale and a visual analogue scale. Scar length and histologic analysis were also evaluated. Clinical assessment scale and visual analogue scale scores showed improved appearance in the untreated external control wounds versus the untreated internal control and treated wounds (p Wound contraction was not significantly different between groups. Histologic characteristics between groups were similar except for epidermal hyperplasia, which was decreased in the untreated external control (p wounds at 0.4 mg/cc for three courses does not improve, and may worsen, clinical appearance and scarring during early healing. There is no difference in histology during the long-term healing process. Scar contraction was unchanged.

    Current standard of care for full-thickness burn is excision followed by autologous split-thickness skin graft placement. Skin grafts are also frequently used to cover surgical wounds not amenable to linear closure. While all grafts have potential to contract, clinical observation suggests that antecedent thermal injury worsens contraction and impairs functional and aesthetic outcomes. This study evaluates the impact of antecedent full-thickness burn on split-thickness skin graft scar outcomes and the potential mediating factors. Full-thickness contact burns (100°C, 30s) were created on the backs of anesthetized female Yorkshire Pigs. After seven days, burn eschar was tangentially excised and covered with 12/1000th inch (300μm) split-thickness skin graft. For comparison, unburned wounds were created by sharp excision to fat before graft application. From 7 to 120days post-grafting, planimetric measurements, digital imaging and biopsies for histology, immunohistochemistry and gene expression were obtained. At 120days post-grafting, the Observer Scar Assessment Scale, colorimetry, contour analysis and optical graft height assessments were performed. Twenty-nine porcine wounds were analyzed. All measured metrics of clinical skin quality were significantly worse (pskin graft quality, likely by multiple mechanisms including burn-related inflammation, microscopically inadequate excision, and dysregulation of tissue remodeling. A valid, reliable, clinically relevant model of full-thickness burn, excision and skin replacement therapy has been demonstrated. Future research to enhance quality of skin replacement therapies should be directed toward modulation of inflammation and assessments for complete excision. Copyright © 2016 Elsevier Ltd and ISBI.

    Full Text Available Background: There has been a recent interest in the double row repair method for arthroscopic rotator cuff repair following favourable biomechanical results reported by some studies. The purpose of this study was to compare the clinical results of arthroscopic single row and double row repair methods in the full-thickness rotator cuff tears. Materials and Methods: 22 patients of arthroscopic single row repair (group I and 25 patients who underwent double row repair (group II from March 2003 to March 2005 were retrospectively evaluated and compared for the clinical outcomes. The mean age was 58 years and 56 years respectively for group I and II. The average follow-up in the two groups was 24 months. The evaluation was done by using the University of California Los Angeles (UCLA rating scale and the shoulder index of the American Shoulder and Elbow Surgeons (ASES. Results: In Group I, the mean ASES score increased from 30.48 to 87.40 and the mean ASES score increased from 32.00 to 91.45 in the Group II. The mean UCLA score increased from the preoperative 12.23 to 30.82 in Group I and from 12.20 to 32.40 in Group II. Each method has shown no statistical clinical differences between two methods, but based on the sub scores of UCLA score, the double row repair method yields better results for the strength, and it gives more satisfaction to the patients than the single row repair method. Conclusions: Comparing the two methods, double row repair group showed better clinical results in recovering strength and gave more satisfaction to the patients but no statistical clinical difference was found between 2 methods.

    Full Text Available "Peritonitis fibrosa incapsulata", first described in 1907, is a condition characterized by encasement of the bowel with a thick fibrous membrane. This condition was renamed as "abdominal cocoon" in 1978. It presents as small bowel obstruction clinically. 35 cases of abdominal cocoon have been reported in the literature over the last three decades. Abdominal cocoon is more common in adolescent girls from tropical countries. Various etiologies have been described, including tubercular. It is treated surgically by releasing the entrapped bowel. We report a laparoscopic experience of tubercular abdominal cocoon and review the literature.

    Stable closure of full-thickness burn wounds remains a limitation to recovery from burns of greater than 50% of the total body surface area (TBSA). Hypothetically, engineered skin substitutes (ESS) consisting of autologous keratinocytes and fibroblasts attached to collagen-based scaffolds may reduce requirements for donor skin, and decrease mortality. ESS were prepared from split-thickness skin biopsies collected after enrollment of 16 pediatric burn patients into an approved study protocol. ESS and split-thickness autograft (AG) were applied to 15 subjects with full-thickness burns involving a mean of 76.9% TBSA. Data consisted of photographs, tracings of donor skin and healed wounds, comparison of mortality with the National Burn Repository, correlation of TBSA closed wounds with TBSA full-thickness burn, frequencies of regrafting, and immunoreactivity to the biopolymer scaffold. One subject expired before ESS application, and 15 subjects received 2056 ESS grafts. The ratio of closed wound to donor areas was 108.7 ± 9.7 for ESS compared with a maximum of 4.0 ± 0.0 for AG. Mortality for enrolled subjects was 6.25%, and 30.3% for a comparable population from the National Burn Repository (P burn generated an R value of 0.65 (P burns of greater than 50% TBSA.

The purpose of this study was to compare the clinical results of arthroscopic single row and double row repair methods in the full-thickness rotator cuff tears. 22 patients of arthroscopic single row repair (group I) and 25 patients who underwent double row repair (group II) from March 2003 to March 2005 were retrospectively evaluated and compared for the clinical outcomes. The mean age was 58 years and 56 years respectively for group I and II. The average follow-up in the two groups was 24 months. The evaluation was done by using the University of California Los Angeles (UCLA) rating scale and the shoulder index of the American Shoulder and Elbow Surgeons (ASES). In Group I, the mean ASES score increased from 30.48 to 87.40 and the mean ASES score increased from 32.00 to 91.45 in the Group II. The mean UCLA score increased from the preoperative 12.23 to 30.82 in Group I and from 12.20 to 32.40 in Group II. Each method has shown no statistical clinical differences between two methods, but based on the sub scores of UCLA score, the double row repair method yields better results for the strength, and it gives more satisfaction to the patients than the single row repair method. Comparing the two methods, double row repair group showed better clinical results in recovering strength and gave more satisfaction to the patients but no statistical clinical difference was found between 2 methods.

    This report describes a testing program that utilizes full-thickness clad beam specimens to quantify fracture toughness for shallow cracks in material for which metallurgical conditions are prototypic of those found in reactor pressure vessels (RPVs). The beam specimens are fabricated from a section of an RPV wall (removed from a canceled nuclear plant) that includes weld, plate, and clad material. Metallurgical factors potentially influencing fracture toughness for shallow cracks in the beam specimens include material gradients due to welding and cladding applications, as well as material inhomogeneities in welded regions due to reheating in multiple weld passes. A summary of the testing program includes a description of the specimen geometry, material properties, the testing procedure, and the experimental results form three specimens. The yield strength of the weld material was determined to be 36% higher than the yield strength of the base material. An irradiation-induced increase in yield strength of the weld material could result in a yield stress that exceeds the upper limit where code curves are valid. The high yield strength for prototypic weld material may have implications for RPV structural integrity assessments. Analyses of the test data are discussed, including comparisons of measured displacements with finite-element analysis results, applications of toughness estimation techniques, and interpretations of constraint conditions implied by stress-based constraint methodologies. Metallurgical conditions in the region of the cladding heat-affected zone are proposed as a possible explanation for the lower-bound fracture toughness measured with one of the shallow-crack clad beam specimens. Fracture toughness data from the three clad beam specimens are compared with other shallow- and deep-crack uniaxial beam and cruciform data generated previously from A 533 Grade B plate material

    Endoscopic full-thickness resection (eFTR) is a minimally invasive method for en bloc resection of GI lesions. The aim of this pilot study was to evaluate the feasibility of a grasp-and-snare technique for eFTR combined with an over-the-scope clip (OTSC) for defect closure. Nonsurvival animal study. Animal laboratory. Fourteen female domestic pigs. The eFTR was performed in porcine colons using a novel tissue anchor in combination with a standard monofilament snare and 14 mm OTSC. In the first group (n = 20), closure of the colonic defects with OTSC was attempted after the resection. In the second group (n = 8), an endoloop was used to secure the resection base before eFTR was performed. In the first group (n = 20), eFTR specimens ranged from 2.4 to 5.5 cm in diameter. Successful closure was achieved in 9 out of 20 cases. Mean burst pressure for OTSC closure was 29.2 mm Hg (range, 2-90; SD, 29.92). Injury to adjacent organs occurred in 3 cases. Lumen obstruction due to the OTSC closure occurred in 3 cases. In the second group (n = 8), the diameter of specimens ranged from 1.2 to 2.2 cm. Complete closure was achieved in all cases, with a mean burst pressure of 76.6 mm Hg (range, 35-120; SD, 31). Lumen obstruction due to the endoloop closure occurred in one case. No other complications or injuries were observed in the second group. Nonsurvival setting. Colonic eFTR using the grasp-and-snare technique is feasible in an animal model. Ligation of the resection base with an endoloop before eFTR seems to reduce complication rates and improve closure success and leak test results despite yielding smaller specimens.

    The hands are commonly affected in severe thermal burn injuries. Resulting contractures lead to significant loss of function. Burn contracture release and skin grafting are necessary to restore hand function. We report a case in which surgical reconstruction of a volar hand burn was performed with full-thickness skin grafting. The patient had a 40-year follow-up to assess the function and cosmesis of the repaired hand. We report a case in which a 15-month-old boy presented after receiving third-degree burns to the left volar hand, including the flexural aspects of the index, long, and ring fingers by placing it on a hot kitchen stove burner. The patient subsequently underwent scar contracture release and full-thickness skin grafting. Eleven years after reconstruction, further contractures developed associated with the patient's growth, which were reconstructed with repeat full-thickness skin graft from the inguinal region. No recurrence was witnessed afterward and 40 years after initial injury, the patient maintains full activities of daily living and use of his hand in his occupation. There is debate regarding the superiority of split-thickness versus full-thickness grafts during reconstruction. Our case strengthens the argument for durability of a full-thickness skin graft following thermal burn injury.

    The purpose of this study was to evaluate the clinical outcomes of cografting of acellular dermal matrix with autologous split-thickness skin and autologous split-thickness skin graft alone for full-thickness skin defects on the extremities. In this prospective randomized study, 19 consecutive patients with full-thickness skin defects on the extremities following trauma underwent grafting using either cograft of acellular dermal matrix with autologous split-thickness skin graft (nine patients, group A) or autologous split-thickness skin graft alone (10 patients, group B) from June of 2011 to December of 2012. The postoperative evaluations included observation of complications (including graft necrosis, graft detachment, or seroma formation) and Vancouver Scar Scale score. No statistically significant difference was found regarding complications, including graft necrosis, graft detachment, or seroma formation. At week 8, significantly lower Vancouver Scar Scale scores for vascularity, pliability, height, and total score were found in group A compared with group B. At week 12, lower scores for pliability and height and total scores were identified in group A compared with group B. For cases with traumatic full-thickness skin defects on the extremities, a statistically significant better result was achieved with cograft of acellular dermal matrix with autologous split-thickness skin graft than with autologous split-thickness skin graft alone in terms of Vancouver Scar Scale score.

    To determine whether internal limiting membrane (ILM) peeling improves anatomic and functional outcomes of full-thickness macular hole (FTMH) surgery when compared with the no-peeling technique. Systematic review and individual participant data (IPD) meta-analysis undertaken under the auspices of the Cochrane Eyes and Vision Group. Only randomized controlled trials (RCTs) were included. Patients with idiopathic stage 2, 3, and 4 FTMH undergoing vitrectomy with or without ILM peeling. Macular hole surgery, including vitrectomy and gas endotamponade with or without ILM peeling. Primary outcome was best-corrected distance visual acuity (BCdVA) at 6 months postoperatively. Secondary outcomes were BCdVA at 3 and 12 months; best-corrected near visual acuity (BCnVA) at 3, 6, and 12 months; primary (after a single surgery) and final (after >1 surgery) macular hole closure; need for additional surgical interventions; intraoperative and postoperative complications; patient-reported outcomes (PROs) (EuroQol-5D and Vision Function Questionnaire-25 scores at 6 months); and cost-effectiveness. Four RCTs were identified and included in the review. All RCTs were included in the meta-analysis; IPD were obtained from 3 of the 4 RCTs. No evidence of a difference in BCdVA at 6 months was detected (mean difference, -0.04; 95% confidence interval [CI], -0.12 to 0.03; P=0.27); however, there was evidence of a difference in BCdVA at 3 months favoring ILM peeling (mean difference, -0.09; 95% CI, -0.17 to-0.02; P=0.02). There was evidence of an effect favoring ILM peeling with regard to primary (odds ratio [OR], 9.27; 95% CI, 4.98-17.24; Ppeeling was found to be highly cost-effective. Available evidence supports ILM peeling as the treatment of choice for patients with idiopathic stage 2, 3, and 4 FTMH. Copyright © 2014 American Academy of Ophthalmology. Published by Elsevier Inc.

    To evaluate the use of corneal donor tissue deemed unsuitable for full-thickness penetrating keratoplasty (PK) for use in deep lamellar endothelial keratoplasty (DLEK) and to compare postoperative results to those of DLEK surgery using donor tissue that is suitable for PK. Small-incision DLEK surgery was performed using 39 donor corneas unsuitable for PK. Thirty-five donors had anterior scars or opacities, 3 donors had pterygia within the 8-mm zone, and 1 had prior LASIK. All donor preparation was completed by manual stromal dissection. The DLEK surgical and postoperative courses were reviewed. Preoperative and 6-month postoperative results of this study group were compared with a control group consisting of the first 55 consecutive small-incision DLEK patients receiving donor corneas that had no criteria excluding them from use in PK. Four eyes in the study group and 1 eye in the control group had the confounding variables of the presence of an anterior-chamber lens or surgical vitrectomy with macular disease in the recipient eye. There was no significant difference in preoperative measurements of best spectacle-corrected visual acuity (BSCVA; P = 0.372), donor endothelial cell density (ECD; P = 0.749), or corneal topography [surface regularity index (SRI), P = 0.485; or surface asymmetry index (SAI), P = 0.154] between the 2 groups. For the patients receiving corneas deemed unacceptable for PK, at 6 months after surgery, the vision (P = 0.002) and corneal topography measurements improved significantly from before surgery (SRI, P < 0.001; SAI, P < 0.001), and there was no significant change in refractive astigmatism (P = 0.240). There was a significant difference in the vision at 6 months postoperatively between the overall study group and the control group, with the mean vision of the study group at 20/56 and the control group at 20/43 (P = 0.015). If eyes with known cystoid macular edema (CME) and vitrectomy are removed from each group, there is no significant

    Full-thickness skingraft is a valid option to release burn scar contractures with the main purpose of correcting the induced limitation in function and improve the disfiguring appearance of the scar. The main pitfall remains the limited availability of these grafts, especially when large sheets are needed. We present an application of a previously described technique known as reverse tissue expansion, which permits the harvesting of a large sheet of full thickness skin graft when needed. This method was adopted to release a burn scar contracture in a 32-yr-old man who sustained a 65% TBSA burn secondary to a gasoline tank explosion at the age of 7 yr followed by multiple reconstructive procedures. The patient presented with a disfiguring anterior neck contracture coupled to limited range of motion. Improvement of neck extension was contemplated using full-thickness skin graft harvested following reverse tissue expansion achieved by deflation liposuction of the donor site.

    Vaginal (re)construction can greatly improve the quality of life of indicated patients. If primary vaginoplasty fails, multiple surgical approaches exist for revision. The authors compared surgical results of laparoscopic intestinal versus full-thickness skin graft revision vaginoplasty. A retrospective chart review of patients who underwent revision vaginoplasty at the authors' institution was conducted. Patient demographics, surgical characteristics, complications, hospitalization, reoperations, and neovaginal depth for both surgical techniques were recorded and compared. The authors studied a consecutive series of 50 transgender and three biological women who underwent revision vaginoplasty, of which 21 were laparoscopic intestinal and 32 were perineal full-thickness skin graft vaginoplasties, with a median clinical follow-up of 3.2 years (range, 0.5 to 19.7 years). Patient demographics did not differ significantly. There was no mortality. Two intraoperative rectal perforations (10 percent) occurred in the intestinal group versus six (19 percent) in the full-thickness skin graft group. Operative time was shorter for the full-thickness skin graft vaginoplasty group (131 ± 35 minutes versus 191 ± 45 minutes; p skin graft (81 percent) vaginoplasty procedures. A deeper neovagina was achieved with intestinal vaginoplasty (15.9 ± 1.4 cm versus 12.5 ± 2.8 cm; p skin graft vaginoplasty can be used as secondary vaginal reconstruction. Intraoperative and postoperative complications do not differ significantly, but rectal perforation was more prevalent in the full-thickness skin graft vaginoplasty group. Although the operative time of laparoscopic intestinal vaginoplasty is longer, adequate neovaginal depth was more frequently achieved than in secondary perineal full-thickness skin graft vaginoplasty.

    Split-skin grafting (SSG) is the gold standard treatment for full-thickness skin defects. For certain patients, however, an extensive skin lesion resulted in inadequacies of the donor site. Tissue engineering offers an alternative approach by using a very small portion of an individual's skin to harvest cells for propagation and biomaterials to support the cells for implantation. The objective of this study was to determine the effectiveness of autologous bilayered tissue-engineered skin (BTES) and single-layer tissue-engineered skin composed of only keratinocytes (SLTES-K) or fibroblasts (SLTES-F) as alternatives for full-thickness wound healing in a sheep model. Full-thickness skin biopsies were harvested from adult sheep. Isolated fibroblasts were cultured using medium Ham's F12: Dulbecco modified Eagle medium supplemented with 10% fetal bovine serum, whereas the keratinocytes were cultured using Define Keratinocytes Serum Free Medium. The BTES, SLTES-K, and SLTES-F were constructed using autologous fibrin as a biomaterial. Eight full-thickness wounds were created on the dorsum of the body of the sheep. On 4 wounds, polyvinyl chloride rings were used as chambers to prevent cell migration at the edge. The wounds were observed at days 7, 14, and 21. After 3 weeks of implantation, the sheep were euthanized and the skins were harvested. The excised tissues were fixed in formalin for histological examination via hematoxylin-eosin, Masson trichrome, and elastin van Gieson staining. The results showed that BTES, SLTES-K, and SLTES-F promote wound healing in nonchambered and chambered wounds, and BTES demonstrated the best healing potential. In conclusion, BTES proved to be an effective tissue-engineered construct that can promote the healing of full-thickness skin lesions. With the support of further clinical trials, this procedure could be an alternative to SSG for patients with partial- and full-thickness burns.

    Elephantiasis nostras verrucosa is a rare cutaneous complication of chronic lymphatic obstruction. It is most commonly caused by bacterial infection, trauma, neoplasia, obesity, and venous stasis. In this report, we describe a case of elephantiasis nostras verrucosa involving the scrotum and perineal area in a 32-year-old. The lesions were excised, and full-thickness skin grafting of the penis, scrotum, and perineal skin was performed. This case demonstrates the efficacy of excision with full-thickness skin grafting of the penis, scrotum, and perineal area in a patient with elephantiasis nostras verrucosa confined to the scrotum and perineal region.

    Low back pain (LBP) is a common complaint amongst adolescent athletes. While different studies have shown association between LBP and trunk muscle thickness in the general population, few articles have studied it in adolescent athletes. The aim of this study is to compare lateral abdominal muscle thickness and function, and cross sectional area (CSA) of lumbar multifidus (LM) in adolescent soccer players with and without LBP. In total, 28 adolescent soccer players with and without LBP, from the premier league participated in this study. The thickness of external oblique, internal oblique and transversus abdominis and the CSA of the LM muscles at L4 level on both sides were measured at rest and contraction via ultrasound imaging (USI). In addition, leg length discrepancy, hamstring flexibility, active lumbar forward flexion, and isometric muscle endurance of trunk extensors were measured in both groups. (study design/setting: case control study). The mean (SD) age in LBP group and non-LBP group were 14.0 (1.1) and 14.1 (0.9) years, respectively. There was no significant difference in baseline characteristics of participants between groups. Findings showed no significant difference between LBP and non-LBP groups comparing all measured variables. The data obtained support that there is not a correlation between abdominal muscle thickness and CSA of the lumbar multifidi and LBP in adolescent soccer players. These findings suggest that other factors rather than the thickness of deep trunk muscles may play a more significant role in the etiology of LBP in adolescent soccer players.

    Full Text Available Wounds with full-thickness skin loss are commonly managed by skin grafting. In the absence of a graft, reepithelialization is imperfect and leads to increased scar formation. Biomaterials can alter wound healing so that it produces more regenerative tissue and fewer scars. This current study use the new chitosan based biomaterial in full-thickness wound with impaired healing on rat model. Wounds were evaluated after being treated with a chitosan dermal substitute, a chitosan skin substitute, or duoderm CGF. Wounds treated with the chitosan skin substitute showed the most re-epithelialization (33.2 ± 2.8%, longest epithelial tongue (1.62 ± 0.13 mm, and shortest migratory tongue distance (7.11 ± 0.25 mm. The scar size of wounds treated with the chitosan dermal substitute (0.13 ± 0.02 cm and chitosan skin substitute (0.16 ± 0.05 cm were significantly decreased (P<0.05 compared with duoderm (0.45 ± 0.11 cm. Human leukocyte antigen (HLA expression on days 7, 14, and 21 revealed the presence of human hair follicle stem cells and fibroblasts that were incorporated into and surviving in the irradiated wound. We have proven that a chitosan dermal substitute and chitosan skin substitute are suitable for wound healing in full-thickness wounds that are impaired due to radiation.

    Oral submucous fibrosis is a chronic debilitating disease characterized by gradually increasing fibrosis of the oral cavity and pharynx, mainly the buccal mucosa, resulting in trismus. The highest incidence of oral submucous fibrosis is seen in South India due to various deleterious habits. In spite of the numerous medical modalities employed in the management of oral submucous fibrosis, occasionally surgical intervention becomes inevitable. Various surgical approaches have been used to reconstruct the surgical defects following excision of fibrous bands. Full thickness skin grafts have been described in the literature with variable outcomes. In the present study a 38-year-old male presented with severe oral submucous fibrosis of the buccal mucosa, which was successfully treated and reconstructed using full thickness skin graft with stable functional result after one year of treatment. An integrated review of the literature regarding etiology, histopathology, diagnostic, and treatment modalities of the disease follows. PMID:23304568

    Penile inversion vaginoplasty is considered to be the gold standard for gender reassignment surgery in transgender women. The use of additional full-thickness skin graft as neovaginal lining is controversial. Some believe that having extra penile skin for the vulva gives better aesthetic results. Others believe that it gives inferior functional results because of insensitivity and skin graft contraction. Transgender women undergoing penile inversion vaginoplasty were studied prospectively. The option to add full-thickness skin graft is offered in patients where the penile skin length lies between 7 and 12 cm. Neovaginal depth was measured at surgery and during follow-up (3, 13, 26, and 52 weeks postoperatively). Satisfaction with the aesthetic result, neovaginal depth, and dilation regimen during follow-up were recorded. Satisfaction, sexual function, and genital self-image were assessed using questionnaires. A total of 100 patients were included (32 with and 68 without additional full-thickness skin graft). Patient-reported aesthetic outcome, overall satisfaction with the neovagina, sexual function, and genital self-image were not significantly associated with surgical technique. The mean intraoperative neovaginal depth was 13.8 ± 1.4 cm. After 1 year, this was 11.5 ± 2.5 cm. The largest decline (-15 percent) in depth is observed in the first 3 postoperative weeks (p skin graft use, in penile inversion vaginoplasty. The additional use of full-thickness skin graft does not influence neovaginal shrinkage, nor does it affect the patient- and physician-reported aesthetic or functional outcome. Therapeutic, IV.

    There is a clinical need for a novel, more efficient therapy for full thickness wound healing. In the current study, curcumin encapsulated PEG-PLA [poly(lactide)-block-poly(ethylene glycol)] nanomicelles were incorporated into dextran hydrogel for a full thickness dermal wound healing application. To assess the application of the hydrogel as a therapeutic wound dressing, its morphology, swelling pattern, kinetics of degradation, and capacity to control curcumin release were evaluated. It was found that the prepared hybrid hydrogel had acceptable biocompatibility, incorporation capacity of curcumin nanomicelles, and mechanical properties. An in vitro release experiment also demonstrated the sustained release of curcumin from dextran hydrogel, which was first controlled by the diffusion of curcumin from hydrogel and continued through hydrogel matrix erosion at the terminal phase. An in vivo wound healing experiment was carried out using dressing hydrogels on full thickness wounds in BALB/c mice. An histological study demonstrated that the application of curcumin nanomicelles incorporated hydrogel could significantly augment the re-epithelialization of epidermis and collagen deposition in the wound area. Expression of CD31 and vimentin in wound tissue was investigated using immunohistochemistry tests on the eighth day post wounding. The results obtained demonstrated that curcumin nanomicelles incorporated hydrogel could significantly accelerate angiogenesis, fibroblast accumulation, and the process of wound healing. Together, the data indicate that the prepared hybrid curcumin PEG-PLA nanomicelles incorporated dextran hydrogel is a promising candidate for full thickness wound treatment that increases re-epithelialization, collagen deposition, angiogenesis, and tissue granulation.

    To report the use of negative pressure wound therapy (NPWT) with polyvinyl alcohol (PVA) foam to bolster full-thickness mesh skin grafts in dogs. Retrospective case series. Client-owned dogs (n = 8). Full-thickness mesh skin graft was directly covered with PVA foam. NPWT was maintained for 5 days (in 1 or 2 cycles). Grafts were evaluated on days 2, 5, 10, 15, and 30 for graft appearance and graft take, granulation tissue formation, and complications. Firm attachment of the graft to the recipient bed was accomplished in 7 dogs with granulation tissue quickly filling the mesh holes, and graft take considered excellent. One dog had bandage complications after cessation of the NPWT, causing partial graft loss. The PVA foam did not adhere to the graft or damage the surrounding skin. The application of NPWT with a PVA foam after full-thickness mesh skin grafting in dogs provides an effective method for securing skin grafts, with good graft acceptance. PVA foam can be used as a primary dressing for skin grafts, obviating the need for other interposing materials to protect the graft and the surrounding skin. © 2017 The American College of Veterinary Surgeons.

    Full Text Available Background: Obesity is a medical condition that may adversely affect wellbeing and leading to increased incidence of many health problems. Abdominal obesity tends to be associated with weight gain and obesity and it is significantly connected with different disorders like coronary heart disease and type II diabetes mellitus.This study was conducted to investigate the efficacy of vacuum therapy as compared to abdominal exercises on abdominal obesity in overweight and obese women. Methods: Thirtyoverweight and obese women participated in this study with body mass index > 25 kg/m2andwaist circumference ≥ 85 cm. Their ages ranged from 28 - 40 years old.The subjects were excluded if they have diabetes, abdominal infection diseases or any physical limitation restricting exercise ability. They were randomly allocated into two equal groups; group I and group II. Group I received vacuum therapy sessions (by the use of LPG device in addition to aerobic exercise training. Group II received abdominal exercises in addition to the same aerobic exercisesgiven to group I. This study was extended for successive 8 weeks (3 sessions/ week. All subjects were assessed for thickness ofnthe abdominal skin fold, waist circumference and body mass index. Results: The results of this study showeda significant difference between group I and group II post-interventionas regarding to the mean values of waist circumference and abdominal skin fold thickness (p<0.05. Conclusion: It can be concluded that aerobic exercises combined with vacuum therapy (for three sessions/week for successive 8 weeks have a positive effect on women with abdominal obesity in terms of reducing waist circumference and abdominal skin fold thickness.

    The internet is becoming an increasingly popular resource to support patient decision-making outside of the clinical encounter. The quality of online health information is variable and largely unregulated. The aim of this study was to assess the quality of online resources to support patient decision-making for full-thickness rectal prolapse surgery. This systematic review was registered on the PROSPERO database (CRD42017058319). Searches were performed on Google and specialist decision aid repositories using a pre-defined search strategy. Sources were analysed according to three measures: (1) their readability using the Flesch-Kincaid Reading Ease score, (2) DISCERN score and (3) International Patient Decision Aids Standards (IPDAS) minimum standards criteria score (IPDASi, v4.0). Overall, 95 sources were from Google and the specialist decision aid repositories. There were 53 duplicates removed, and 18 sources did not meet the pre-defined eligibility criteria, leaving 24 sources included in the full-text analysis. The mean Flesch-Kincaid Reading Ease score was higher than recommended for patient education materials (48.8 ± 15.6, range 25.2-85.3). Overall quality of sources supporting patient decision-making for full-thickness rectal prolapse surgery was poor (median DISCERN score 1/5 ± 1.18, range 1-5). No sources met minimum decision-making standards (median IPDASi score 5/12 ± 2.01, range 1-8). Currently, easily accessible online health information to support patient decision-making for rectal surgery is of poor quality, difficult to read and does not support shared decision-making. It is recommended that professional bodies and medical professionals seek to develop decision aids to support decision-making for full-thickness rectal prolapse surgery.

    Human artificial skin models are increasingly employed as non-animal test platforms for research and medical purposes. However, the overall histopathological quality of such models may vary significantly. Therefore, the effects of manufacturing protocols and donor sources on the quality of skin models built-up from fibroblasts and keratinocytes derived from juvenile foreskins is studied. Histo-morphological parameters such as epidermal thickness, number of epidermal cell layers, dermal thickness, dermo-epidermal adhesion and absence of cellular nuclei in the corneal layer are obtained and scored accordingly. In total, 144 full-thickness skin models derived from 16 different donors, built-up in triplicates using three different culture conditions were successfully generated. In univariate analysis both media and donor age affected the quality of skin models significantly. Both parameters remained statistically significant in multivariate analyses. Performing general linear model analyses we could show that individual medium-donor-interactions influence the quality. These observations suggest that the optimal choice of media may differ from donor to donor and coincides with findings where significant inter-individual variations of growth rates in keratinocytes and fibroblasts have been described. Thus, the consideration of individual medium-donor-interactions may improve the overall quality of human organ models thereby forming a reproducible test platform for sophisticated clinical research.

    Traditional donor-site closure has been associated with serious esthetic and functional morbidity. The purpose of this study was to assess morbidity in esthetics and function and measure the postoperative complications of the radial forearm free flap (RFFF) donor site after using combined local triangular full-thickness skin grafting. This prospective study of patients who underwent reconstruction of head and neck defects using an RFFF was conducted from July 2008 through December 2014. The donor site was repaired with a combined local triangular full-thickness skin graft. Quality of the scar, color match, tendon exposure, presence of necrosis, dehiscence of the suture, and presence of dysesthesia were recorded and analyzed using SPSS 21.0 software. One hundred consecutive patients (71 male and 29 female) underwent RFFF harvesting. RFFF donor-site defects ranged from 15 to 70 cm2; partial skin graft loss occurred in 7% of patients. Five patients (5%) had small dehiscences of the forearm skin graft, and 2 cases (2%) presented tendon exposure. In all cases, these sites healed secondarily by conservative management, with no final impairment of function. Esthetic results were considered excellent in 87%, good in 11%, and suboptimal in 2% of the cases. The combined local triangular full-thickness skin graft is a reliable method for closing RFFF donor-site defects because it obviates a second surgical site, it provides excellent color match and pliability, and it can be used for covering large defects of the donor site.

    Full Text Available Endometriosis is defined as the presence of endometrial mucosa (glands and stroma abnormally implanted in locations other than the uterine cavity. Deep infiltrating endometriosis (DIE is considered the most aggressive presentation of the disease, penetrating more than 5 mm in affected tissues, and it is reported in approximately 20% of all women with endometriosis. DIE can cause a complete distortion of the pelvic anatomy and it mainly involves uterosacral ligaments, bladder, rectovaginal septum, rectum, and rectosigmoid colon. This review describes the state of the art in laparoscopic approach for DIE with a special interest in intestinal involvement, according to recent literature findings. Our attention has been focused particularly on full-thickness excision versus shaving technique in deep endometriosis intestinal involvement. Particularly, the aim of this paper is clarifying from the clinical and methodological points of view the best surgical treatment of deep intestinal endometriosis, since there is no standard of care in the literature and in different surgical settings. Indeed, this review tries to suggest when it is advisable to manage the full-thickness excision or the shaving technique, also analyzing perioperative management, main complications, and surgical outcomes.

    Xeroderma pigmentosum is an autosomal recessive disease, characterized by vulnerability of the skin to solar radiation. Increase in sunlight-induced cancer is a direct consequence of an increase in mutated cells of the skin of patients with xeroderma pigmentosum. There is no specific technique for facial resurfacing in patients with xeroderma pigmentosum. In this article, a patient with xeroderma pigmentosum with multiple malignant melanomas on her face and radical excision of total facial skin followed by facial resurfacing with monoblock full-thickness skin graft from the abdomen is presented.

    Endoscopic full-thickness resection (EFTR) in the lower gastrointestinal tract may be a valuable therapeutic and diagnostic approach for a variety of indications. Although feasibility of EFTR has been demonstrated, there is a lack of safe and effective endoscopic devices for routine use. The aim of this study was to investigate the efficacy and safety of a novel over-the-scope device for colorectal EFTR. Between July 2012 and July 2014, 25 patients underwent EFTR at two tertiary referral centers. All resections were performed using the full-thickness resection device (FTRD; Ovesco Endoscopy, Tübingen, Germany). Data were collected retrospectively. Indications for EFTR were: recurrent or incompletely resected adenoma with nonlifting sign (n = 11), untreated adenoma and nonlifting sign (n = 2), adenoma involving the appendix (n = 5), flat adenoma in a patient with coagulopathy (n = 1), diagnostic re-resection after incomplete resection of a T1 carcinoma (n = 2), adenoma involving a diverticulum (n = 1), submucosal tumor (n = 2), and diagnostic resection in a patient with suspected Hirschsprung's disease (n = 1). In one patient, the lesion could not be reached because of a sigmoid stenosis. In the other patients, resection of the lesion was macroscopically complete and en bloc in 20/24 patients (83.3 %). The mean diameter of the resection specimen was 24 mm (range 12 - 40 mm). The R0 resection rate was 75.0 % (18/24), and full-thickness resection was histologically confirmed in 87.5 %. No perforations or major bleeding were observed during or after resection. Two patients developed postpolypectomy syndrome, which was managed with antibiotic therapy. Full-thickness resection in the lower gastrointestinal tract with the novel FTRD was feasible and effective. Prospective studies are needed to further evaluate the device and technique. © Georg Thieme Verlag KG Stuttgart · New York.

    To evaluate the effect of 2 different protocols of intra-articular hyaluronic acid (HA, hylan G-F20) to articular cartilage regeneration in acute full-thickness chondral defects. Full-thickness chondral defects of 3 x 6 mm were performed into the lateral femoral condyles of New Zealand rabbits, treated with a single or three doses of HA. The animals were sacrified at 12 weeks and the regenerated tissue was evaluated by direct observation and histology with the ICRS scale. Macroscopically, in both groups treated with HA the defects were filled with irregular tissue with areas similar to hyaline cartilage and others in which depressed areas with exposed subchondral bone were observed. Histological analysis showed in both groups treated with HA a hyaline-like cartilage compared to control group. However, the score of the International Cartilage Repair Society (ICRS) scale did not show differences between the groups treated with HA. The use of single dose or 3 doses of AH in acute chondral lesions has a limited and similar benefit in articular cartilage regeneration. Copyright © 2014 SECOT. Published by Elsevier Espana.

    Background: In daily practice, we discovered one of the secondary magnetic resonance (MR) findings of the subscapularis (SSC) tendon tear, the 'bridging sign', which has not been previously described. Purpose: To describe the 'bridging sign' on shoulder MR imaging and its radiological and clinical significance in patients with SSC tendon tear. Material and Methods: Twenty-nine patients who had undergone shoulder arthroscopy and had full-thickness tear of the subscapularis tendon were enrolled. The medical records of the 29 patients were retrospectively reviewed for the duration of shoulder pain, rotator cuff tears, and associated arthroscopic findings: biceps tendon abnormality and superior glenoid labral tear. Then, preoperative shoulder MR images were retrospectively reviewed for the presence or absence of the 'bridging sign' and associated MR findings: periarticular fluid and fatty atrophy of the supraspinatus and subscapularis muscles. The type of rotator cuff tear associated with the 'bridging sign' was assessed and the sensitivity, specificity, and accuracy of the 'bridging sign' for the diagnosis of a certain type of rotator cuff tear were calculated. Associated arthroscopic and MR findings and mean duration of the shoulder pain between the patients with and without the 'bridging sign' were compared. Results: The 'bridging sign' was seen in 17 of 29 patients and corresponded to a complex of the torn and superomedially retracted subscapularis tendon, coracohumeral ligament, and superior glenohumeral ligament, adhered to the anterior margin of the torn supraspinatus (SSP) tendon on arthroscopy. All patients with the 'bridging sign' had combined full-thickness tear (FTT) of the cranial 1/2 portion of the subscapularis tendon and anterior 1/2 portion of the SSP tendon. The sensitivity, specificity, and accuracy of the 'bridging sign' for the diagnosis of combined FTTs of the SSC tendon and anterior portion of the SSP tendon were 81.0%, 100%, and 86

    The association between clinical symptoms and sleep disorders in functional dyspepsia (FD)-overlap syndrome has not been studied in detail. The subjects were 139 patients with FD, 14 with irritable bowel syndrome (IBS), 12 with nonerosive reflux disease (NERD), and 41 healthy volunteers. Gastric motility was evaluated with the (13)C-acetate breath test. We used Rome III criteria to evaluate upper abdominal symptoms, and Self-Rating Questionnaire for Depression (SRQ-D) scores to determine depression status. Sleep disorders were evaluated with Pittsburgh Sleep Quality Index (PSQI) scores. There were no significant differences in age, body-mass index, alcohol intake, and smoking rate between patients with FD alone and those with FD-overlap syndrome. The postprandial abdominal fullness score in patients with FD-NERD-IBS was significantly greater than that in patients with FD-NERD overlap syndrome (pSleep Quality Index score in subjects with FD-NERD-IBS overlap syndrome was significantly greater than that in subjects with FD alone. Symptom scores, such as those for postprandial abdominal fullness, heartburn, and the feeling of hunger, in patients with FD-overlap syndromes are significantly greater than those in patients with FD alone. Further studies are necessary to clarify whether various symptoms are related to sleep disorders in patients with FD-NERD-IBS overlap syndrome.

    Full Text Available Abstract Background A full-thickness macular hole (FTMH is a common retinal condition associated with impaired vision. Randomised controlled trials (RCTs have demonstrated that surgery, by means of pars plana vitrectomy and post-operative intraocular tamponade with gas, is effective for stage 2, 3 and 4 FTMH. Internal limiting membrane (ILM peeling has been introduced as an additional surgical manoeuvre to increase the success of the surgery; i.e. increase rates of hole closure and visual improvement. However, little robust evidence exists supporting the superiority of ILM peeling compared with no-peeling techniques. The purpose of FILMS (Full-thickness macular hole and Internal Limiting Membrane peeling Study is to determine whether ILM peeling improves the visual function, the anatomical closure of FTMH, and the quality of life of patients affected by this disorder, and the cost-effectiveness of the surgery. Methods/Design Patients with stage 2–3 idiopathic FTMH of less or equal than 18 months duration (based on symptoms reported by the participant and with a visual acuity ≤ 20/40 in the study eye will be enrolled in this FILMS from eight sites across the UK and Ireland. Participants will be randomised to receive combined cataract surgery (phacoemulsification and intraocular lens implantation and pars plana vitrectomy with postoperative intraocular tamponade with gas, with or without ILM peeling. The primary outcome is distance visual acuity at 6 months. Secondary outcomes include distance visual acuity at 3 and 24 months, near visual acuity at 3, 6, and 24 months, contrast sensitivity at 6 months, reading speed at 6 months, anatomical closure of the macular hole at each time point (1, 3, 6, and 24 months, health related quality of life (HRQOL at six months, costs to the health service and the participant, incremental costs per quality adjusted life year (QALY and adverse events.

    Wounds in reptiles are a common reason for presentation to a veterinarian. At this time there is limited information on effective topical medications to aid in wound closure. The objectives of this study were to translate the splinted, full-thickness dermal wound model, validated in mice, to the bearded dragon (Pogona vitticeps) and to determine the effect of topical becaplermin (BP), a platelet-derived growth factor (0.01%), on the rate of wound closure. Ten bearded dragons were anesthetized and two full-thickness cutaneous wounds were made on the dorsum of each lizard. Encircling splints were applied surrounding each wound and subsequently covered by a semi-occlusive dressing. Five lizards had one wound treated with BP and the adjacent wound treated with a vehicle control. Five additional lizards had one wound treated with saline and the second wound treated with a vehicle control. Wounds were imaged daily, and the wound area was measured using digital image analysis. The change in percentage wound closure over 17 days and the time to 50% wound closure was compared among the four treatment groups. There was no significant difference in wound closure rates between BP-treated and saline-treated wounds or in the time to 50% wound closure between any treatments. Vehicle-treated wounds adjacent to saline-treated wounds closed significantly slower than did BP (P dragons. When compared with saline, BP did not have a significant effect on wound closure rates, while the vehicle alone delayed wound closure. Histologic analysis of experimentally created wounds throughout the wound healing process is needed to further evaluate the effects of these treatments on reptile dermal wound healing.

    The use of platelet-rich plasma (PRP) is an innovative clinical therapy, especially in arthroscopic rotator cuff repair. The purpose of this study was to compare the clinical improvement and tendon-to-bone healing with and without PRP therapy in arthroscopic rotator cuff repair. A systematic search was done in the major medical databases to evaluate the studies using PRP therapy (PRP+) or with no PRP (PRP-) for the treatment of patients with rotator cuff tears. We reviewed clinical scores such as the Constant score, the American Shoulder and Elbow Surgeons score, the University of California at Los Angeles (UCLA) Shoulder Rating Scale, the Simple Shoulder Test, and the failure-to-heal rate by magnetic resonance imaging between PRP+ and PRP- groups. Five studies included in this review were used for a meta-analysis based on data availability. There were no statistically significant differences between PRP+ and PRP- groups for overall outcome scores (P > .05). However, the PRP+ group exhibited better healing rates postoperatively than the PRP- group (P = .03) in small/moderate full-thickness tears. The use of PRP therapy in full-thickness rotator cuff repairs showed no statistically significant difference compared with no PRP therapy in clinical outcome scores, but the failure-to-heal rate was significantly decreased when PRP was used for treatment of small-to-moderately sized tears. PRP therapy may improve tendon-to-bone healing in patients with small or moderate rotator cuff tears. Copyright © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

    The aim of this trial was to determine whether obese patients benefit from treatment with rimonabant in terms of progression of carotid atherosclerosis. Rimonabant, a selective cannabinoid-1 receptor blocker, reduces body weight and improves cardiometabolic risk factors in patients who are obese. A prospective, double-blind, placebo-controlled trial (Atherosclerosis Underlying Development assessed by Intima-media Thickness in patients On Rimonabant (AUDITOR)) randomised 661 patients with abdominal obesity and metabolic syndrome to rimonabant or placebo for 30 months of treatment. The absolute change in the average value for six segments of far wall carotid intima-media thickness from baseline to month 30 was 0.010 ± 0.095 mm in the rimonabant group and 0.012 ± 0.091 mm in the placebo group (p=0.67). The annualised change was an increase of 0.005 ± 0.042 mm for the rimonabant-treated group and 0.007 ± 0.043 mm for the placebo-treated group (p=0.45). There was no difference in atherosclerosis progression between patients receiving rimonabant for 30 months and those receiving placebo for the primary efficacy measure (absolute change in carotid intima-media thickness). These findings are consistent with a similar study using coronary intravascular ultrasound and another study evaluating the occurrence of cardiovascular events. Our findings suggest that a 5% loss of body weight over a 30-month period with rimonabant is insufficient to modify atherosclerosis progression in the carotid artery in obese patients with metabolic syndrome.

    Chronic wounds such as diabetic foot ulcers and venous leg ulcers are common problems in people suffering from type 2 diabetes. These can cause pain, and nerve damage, eventually leading to foot or leg amputation. These types of wounds are very difficult to treat and sometimes take months or even years to heal because of many possible complications during the process. Allogeneic skin grafting has been used to improve wound healing, but the majority of grafts do not survive several days after being implanted. We have been studying the behavior of fibroblasts and keratinocytes in engineered capillary-like endothelial networks. A dermo-epidermal graft has been implanted in an athymic nude mouse model to assess the integration with the host tissue as well as the wound healing process. To build these networks into a skin graft, a modified inkjet printer was used, which allowed the deposit of human microvascular endothelial cells. Neonatal human dermal fibroblast cells and neonatal human epidermal keratinocytes were manually mixed in the collagen matrix while endothelial cells printed. A full-thickness wound was created at the top of the back of athymic nude mice and the area was covered by the bilayered graft. Mice of the different groups were followed until completion of the specified experimental time line, at which time the animals were humanely euthanized and tissue samples were collected. Wound contraction improved by up to 10% when compared with the control groups. Histological analysis showed the neoskin having similar appearance to the normal skin. Both layers, dermis and epidermis, were present with thicknesses resembling normal skin. Immunohistochemistry analysis showed favorable results proving survival of the implanted cells, and confocal images showed the human cells' location in the samples that were collocated with the bilayer printed skin graft.

    PurposeTo report OCT appearance and surgical outcomes of full-thickness macular holes (MHs) accidentally caused by laser devices.Patients and methodsThis retrospective case series included 11 eyes of 11 patients with laser-induced MHs treated by pars plana vitrectomy, internal limiting membrane (ILM) peeling, and gas or silicone oil tamponade. Evaluations included a full ophthalmic examination, macular spectral-domain optical coherence tomography (SD-OCT), and fundus photography. Main outcome measures is MH closure and final visual acuity; the secondary outcome was the changes of retinal pigment epithelium and photoreceptor layer evaluated by sequential post-operative SD-OCT images.ResultsFive patients were accidentally injured by a yttrium aluminum garnet (YAG) laser and six patients by handheld laser. MH diameters ranged from 272 to 815 μm (mean, 505.5±163.0 μm) preoperatively. Best-corrected visual acuity (BCVA) improved from a mean of 0.90 logMAR (range, counting finger-8/20) preoperatively to a mean of 0.34 logMAR (range, a counting finger-20/20) postoperatively (P=0.001, t=4.521). Seven of 11 patients (63.6%) achieved a BCVA better than 10/20. Ten patients had a subfoveal hyperreflectivity and four patients had a focal choroidal depression subfoveal preoperatively. At the last follow-up, all 11 eyes demonstrated the following: closure of the macular hole, variable degrees of disruption of external limiting membrane (ELM) and outer photoreceptor ellipsoid and interdigitation bands. In 10 eyes, the disruption was in the form of focal defects in the outer retina. After surgery, the subfoveal hyperreflectivity and focal choroidal depression remained.ConclusionAccidental laser-induced full-thickness macular holes can be successfully closed with surgery. Inadvertent retinal injury from laser devices, especially handheld laser injury has occurred with increasing frequency in recent years. However, there is a paucity of data regarding these types of injuries

    Full Text Available Healing effects of propolis and silver sulfadiazine (SS on skin wounds in rats were compared using qualitative and quantitative parameters and histopathological findings. A total of 30 full thickness skin wounds were created on dorsal aspects of 10 rats; i.e., three wounds on each rat. Of these wounds, 10 each were allocated to group A (propolis, group B (SS and group C (control. The skin wounds in the rats of groups A, B and C were covered daily for 14 days with 50% propolis cream, SS skin cream and bepanthane cream (control, respectively. Postoperatively, the wound surfaces were examined macroscopically and the healing process and the rates of wound expansion, contraction and epithelialization processes were quantitatively analyzed. As a result, propolis was found in general to have a better wound healing effect than others. At the 10th day of experiment histopathologically, there was inflammatory reaction with infiltration of lymphocytes, macrophages and neutrophils and proliferation of fibroblastic loose connective tissue in dermis of rats of all groups. The severity of these changes was lower in propolis treated group compared to other two groups.

    Full Text Available For most xenobiotics, the rates of percutaneous absorption are limited by diffusion through the horny layer of skin. However, percutaneous absorption of chemicals may seriously increase when the skin is damaged. The aim of this work was to develop an in vitro representative model of mechanically damaged skins. The epidermal barrier was examined following exposure to a razor, a rotating brush, and a microneedle system in comparison to tape-stripping which acted as a reference. Excised full-thickness skins were mounted on a diffusion chamber in order to evaluate the effect of injuries and to mimic physiological conditions. The transepidermal water loss (TEWL was greatly increased when the barrier function was compromised. Measurements were made for all the damaged biopsies and observed histologically by microscopy. On human and porcine skins, the tape-stripping application (0 to 40 times showed a proportional increase in TEWL which highlights the destruction of the stratum corneum. Similar results were obtained for all cosmetic instruments. This is reflected in our study by the nonsignificant difference of the mean TEWL scores between 30 strips and mechanical damage. For a specific appreciation, damaged skins were then selected to qualitatively evaluate the absorption of a chlorogenic acid solution using fluorescence microscopy.

    Full Text Available Hydrogel-based wound dressings provide a cooling sensation, a moist environment, and act as a barrier to microbes for wounds. In this study, a series of soft, flexible, porous non-stick hydrogel dressings were prepared through the simple repeated freeze-thawing of a poly(vinyl alcohol, human-like collagen (or and carboxymethyl chitosan mixed solution rather than chemical cross-linking and Tween80 was added as pore-forming agent for cutaneous wound healing. Some of their physical and chemical properties were characterized. Interestingly, hydrogel PVA-HLC-T80 and PVA-HLC-CS-T80 presented excellent swelling ratios, bacterial barrier activity, moisture vapor permeability, hemostasis activity and biocompatibility. Furthermore, in vivo evaluation of the healing capacity of these two hydrogels was checked by creating a full-thickness wound defect (1.3 cm × 1.3 cm in rabbit. Macroscopic observation and subsequent hematoxylin eosin staining (H&E staining and transmission electron microscopy (TEM analysis at regular time intervals for 18 days revealed that the hydrogels significantly enhanced wound healing by reducing inflammation, promoting granulation tissue formation, collagen deposition and accelerating re-epithelialization. Taken together, the obtained data strongly encourage the use of these multifunctional hydrogels for skin wound dressings.

    Obesity in pregnancy is associated with a number of adverse outcomes. The effects of central versus general obesity in pregnancy have not been well established. To compare subcutaneous fat thickness (SFT) with body mass index (BMI) as a marker for pregnancy outcomes. A stratified retrospective cohort study was performed on 1200 pregnancies, selected from a total of 4862 nulliparous, nonsmoking women between 2006 and 2010. SFT was measured on routine ultrasound at 18-22 weeks gestation. BMI and SFT measurements were compared for estimating risks for obesity-related pregnancy outcomes using logistic regression adjusted for maternal age. The median SFT was 18.2 mm (range 6.3-50.9 mm), the median BMI was 23.8 kg/m(2) (range 15.2-52.5), and the correlation between SFT and BMI was 0.53. For every 5 mm increase in SFT and every 5 kg/m(2) increase in BMI, the odds ratios for developing gestational diabetes mellitus were 1.40 (CI 1.22-1.61, P gestational age 1.28 (CI 1.16-1.47, P = 0.001) and 1.10 (CI 0.95-1.28, P = 0.16) and cumulative adverse obesity-related pregnancy outcomes 1.16 (CI 1.10-1.28, P = 0.002) and 1.05 (CI 0.95-1.16, P = 0.45), respectively. SFT at 18-22 weeks gestation is better than BMI as a marker for obesity-related pregnancy outcomes. As SFT is considered a surrogate measure for visceral fat, these results suggest that central obesity is a stronger risk factor than general adiposity in pregnancy. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Background Full-thickness cartilage lesions of the patella represent a common source of pain and dysfunction. Previously reported surgical treatment options include marrow stimulation, cell-based treatments, and osteochondral transfer. Minced juvenile allograft cartilage is a novel treatment option that allows for a single stage approach for these lesions. Hypothesis Particulated juvenile allograft cartilage (PJAC) for the treatment of chondral defects of the patella would offer acceptable lesion fill rates, mature over time, and not be associated with any negative biologic effects on the surrounding tissue. Methods A retrospective chart review of prospectively collected data was conducted to identify consecutive patients who were treated with PJAC for a full thickness symptomatic cartilage lesion. Qualitative (fast spin echo) and quantitative (T2 mapping) magnetic resonance imaging (MRI) was undertaken at the 6-, 12-, and 24-month postoperative mark. Numerous patient, lesion, and graft specific factors were assessed against MRI scores and percent defect fill of the graft. Graft maturation over time was also assessed. Results Forty-five patients total were included in the study. Average age at the time of surgery was 26.5 years (range 13-45 years), average lesion size was 208 mm 2 (range 4-500 mm 2 ), and average donor age was 49.5 months (range 3-120 months). Sixty percent of the patients were female, while 93% of all patients underwent a concomitant procedure at the time of the index operation. Six-month MRI findings revealed that no patient-, graft-, or donor-specific factors correlated with MR scores, and 82% of the knees demonstrated good to excellent fill. Twelve-month MRI findings revealed that T2 relaxation times of deep graft demonstrated negative correlation with patient age ( P = 0.049) and donor age ( P = 0.006), the integration zone showed a negative correlation with donor age ( P = 0.026). In all, 85% of patients at 12 months displayed good to

    Endoscopic full-thickness resection (EFTR) is a novel treatment of colorectal lesions not amenable to conventional endoscopic resection. The aim of this prospective multicentre study was to assess the efficacy and safety of the full-thickness resection device. 181 patients were recruited in 9 centres with the indication of difficult adenomas (non-lifting and/or at difficult locations), early cancers and subepithelial tumours (SET). Primary endpoint was complete en bloc and R0 resection. EFTR was technically successful in 89.5%, R0 resection rate was 76.9%. In 127 patients with difficult adenomas and benign histology, R0 resection rate was 77.7%. In 14 cases, lesions harboured unsuspected cancer, another 15 lesions were primarily known as cancers. Of these 29 cases, R0 resection was achieved in 72.4%; 8 further cases had deep submucosal infiltration >1000 µm. Therefore, curative resection could only be achieved in 13/29 (44.8%). In the subgroup with SET (n=23), R0 resection rate was 87.0%. In general, R0 resection rate was higher with lesions ≤2 cm vs >2 cm (81.2% vs 58.1%, p=0.0038). Adverse event rate was 9.9% with a 2.2% rate of emergency surgery. Three-month follow-up was available from 154 cases and recurrent/residual tumour was evident in 15.3%. EFTR has a reasonable technical efficacy especially in lesions ≤2 cm with acceptable complication rates. Curative resection rate for early cancers was too low to recommend its primary use in this indication. Further comparative studies have to show the clinical value and long-term outcome of EFTR in benign colorectal lesions.

    Reconstruction of full-thickness defects may benefit from integration of dermal substitutes, which serve as a foundation for split-thickness skin grafts, thus enhancing short and long-term results. We present a series of 7 patients who were treated between 2010 and 2012 for complicated full-thickness defects by the second-generation collagen/elastin matrix Matriderm® covered by a split-thickness skin graft. The defects resulted from malignancy resection, trauma, and post-burn scar reconstruction. Overall graft take was excellent and no complications were noted regarding the dermal substitute. Graft quality was close to normal skin in terms of elasticity, pliability, texture, and color. Good contour and cushioning of defects in weight bearing areas was also achieved. Matriderm was found to be a useful adjunct to full-thickness defect reconstruction, especially in difficult areas where the desired result is a scar of the highest quality possible.

    Wound healing is a major burden of healthcare systems worldwide and hydrogel dressings offer a moist environment conducive to healing. We describe cysteine-containing ultrashort peptides that self-assemble spontaneously into hydrogels. After disulfide crosslinking, the optically-transparent hydrogels became significantly stiffer and exhibited high shape fidelity. The peptide sequence (LIVAGKC or LK6C) was then chosen for evaluation on mice with full-thickness excision wounds. Crosslinked LK6C hydrogels are handled easily with forceps during surgical procedures and offer an improvement over our earlier study of a non-crosslinked peptide hydrogel for burn wounds. LK6C showed low allergenic potential and failed to provoke any sensitivity when administered to guinea pigs in the Magnusson-Kligman maximization test. When applied topically as a dressing, the medium-infused LK6C hydrogel accelerated re-epithelialization compared to controls. The peptide hydrogel is thus safe for topical application and promotes a superior rate and quality of wound healing.

    Osteoradionecrosis of the jaws mainly occurs in the mandible but rarely in the maxilla due to anatomical factors. This report describes a rare case of maxillary osteoradionecrosis that occurred 2 years 2 months after treatment of advanced cancer of the maxillary sinus. Because of advanced cancer of the maxillary sinus (T3N0M0), a 74-years-old female underwent 50 Gy irradiation with intraarterial infusion of 2,500 mg 5-Fu, tumor reduction surgery, and 24 Gy intracavitary brachytherapy with high dose rate iridium from March to May in 1993. While the cancer was well controlled by these treatments, the patient was found to have abscess formation in the left infraorbital region on June 26, 1995 and referred to our department on July 10, 1995. After incision of the abscess, conservation treatment was given to the patient as an outpatient; sequestration began to occur; and the sequester (24 x 15 mm) in the left orbital base was separated on October 17, 1995. Although the inflammation disappeared, a full-thickness skin defect (18 x 8 mm) penetrating through the maxillary sinus in the left infraorbital region developed. This defect was reconstructed by using the triangular hinge flap below it and the buccal flap. The result of reconstruction was esthetically satisfactory. (author)

    Analysis of pre-operative spectral domain optical coherence tomography (SD-OCT) characteristics of full-thickness macular holes (FTMH) and effect on optimum management. We retrospectively reviewed SD-OCT characteristics of a consecutive cohort of patients waitlisted for FTMH surgery and categorized them by current evidence-based treatments. Out of the 106 holes analysed, 36 were small, 40 medium and 30 large. Initially, 33 holes had vitreomacular adhesion (VMA). 41 holes were analysed for change in characteristics with a median duration of 8 weeks between the scans. The number of small or medium holes decreased from 20 to 6 and that of large holes doubled. The number of holes with VMA halved. Smaller hole size (p = 0.014) and being phakic (p = 0.048) were associated with a larger increase in size. The strongest predictor of hole progression into a different surgical management category was the presence of VMA. FTMH characteristics can change significantly pre-operatively and affect optimal treatment choice.

    A testing program is described that utilizes full-thickness clad beam specimens to quantify fracture toughness for shallow cracks in material for which metallurgical conditions are prototypic of those found in reactor pressure vessels (RPVs). The beam specimens are fabricated from a section of an RPV shell (removed from a canceled nuclear plant) that includes weld, plate, and clad material. A summary of the testing program includes a description of the specimen geometry, material properties, the testing procedure, and the experimental results from three specimens. The yield strength of the weld material was determined to be 36% higher than the base material. The high yield strength for prototypic weld material may be implications for RPV integrity assessments. Fracture toughness data from three clad beam specimens are compared with other shallow- and deep-crack beam cruciform data generated previously from A 533 Grade B plate material. Difficulties with interpreting lower-bound fracture toughness curves constructed from the shallow-crack data are essentially resolved by adopting a single normalizing temperature parameter, namely, the nil-ductility transition temperature (NDT)

    In recent years, the use of electronic cigarettes (e-cigarettes) has increased worldwide. Most electronic nicotine delivery systems use rechargeable lithium-ion batteries, which are relatively safe, but in rare cases these batteries can spontaneously combust, leading to serious full and partial thickness burn injuries. Explosions from lithium-ion batteries can cause a flash fire and accelerant-related burn injuries. A retrospective chart review was conducted of 3 patients with lithium-ion battery burns seen at our Level I community-based trauma center. Clinical presentation, management, and outcome are presented. All 3 patients sustained burn injuries (total body surface area range 5-13%) from the spontaneous combustion of lithium-ion batteries used for e-cigarettes. All patients were treated with debridement and local wound care. All fully recovered without sequelae. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians can expect to treat burn cases due to spontaneous lithium-ion battery combustion as e-cigarette use continues to increase. The cases presented here are intended to bring attention to lithium-ion battery-related burns, prepare physicians for the clinical presentation of this burn mechanism, and facilitate patient education to minimize burn risk.

    Bacterial cellulose (BC) is a kind of nanobiomaterial for tissue engineering. How the nanoscale structure of BC affects skin wound repair is unexplored. Here, the hierarchical structure of BC films and their different effects on skin wound healing were studied both in vitro and in vivo. The bottom side of the BC film had a larger pore size, and a looser and rougher structure than that of the top side. By using a microfluidics-based in vitro wound healing model, we revealed that the bottom side of the BC film can better promote the migration of cells to facilitate wound healing. Furthermore, the full-thickness skin wounds on Wistar rats demonstrated that, compared with gauze and the top side of the BC film, the wound covered by the bottom side of the BC film showed faster recovery rate and less inflammatory response. The results indicate that the platform based on the microfluidic chip provide a rapid, reliable, and repeatable method for wound dressing screening. As an excellent biomaterial for wound healing, the BC film displays different properties on different sides, which not only provides a method to optimize the biocompatibility of wound dressings but also paves a new way to building heterogeneous BC-based biomaterials for complex tissue engineering.

  13. Microporous dermal-mimetic electrospun scaffolds pre-seeded with fibroblasts promote tissue regeneration in full-thickness skin wounds.

    Full Text Available Electrospun scaffolds serve as promising substrates for tissue repair due to their nanofibrous architecture and amenability to tailoring of chemical composition. In this study, the regenerative potential of a microporous electrospun scaffold pre-seeded with dermal fibroblasts was evaluated. Previously we reported that a 70% collagen I and 30% poly(Ɛ-caprolactone electrospun scaffold (70:30 col/PCL containing 160 μm diameter pores had favorable mechanical properties, supported fibroblast infiltration and subsequent cell-mediated deposition of extracellular matrix (ECM, and promoted more rapid and effective in vivo skin regeneration when compared to scaffolds lacking micropores. In the current study we tested the hypothesis that the efficacy of the 70:30 col/PCL microporous scaffolds could be further enhanced by seeding scaffolds with dermal fibroblasts prior to implantation into skin wounds. To address this hypothesis, a Fischer 344 (F344 rat syngeneic model was employed. In vitro studies showed that dermal fibroblasts isolated from F344 rat skin were able to adhere and proliferate on 70:30 col/PCL microporous scaffolds, and the cells also filled the 160 μm pores with native ECM proteins such as collagen I and fibronectin. Additionally, scaffolds seeded with F344 fibroblasts exhibited a low rate of contraction (~14% over a 21 day time frame. To assess regenerative potential, scaffolds with or without seeded F344 dermal fibroblasts were implanted into full thickness, critical size defects created in F344 hosts. Specifically, we compared: microporous scaffolds containing fibroblasts seeded for 4 days; scaffolds containing fibroblasts seeded for only 1 day; acellular microporous scaffolds; and a sham wound (no scaffold. Scaffolds containing fibroblasts seeded for 4 days had the best response of all treatment groups with respect to accelerated wound healing, a more normal-appearing dermal matrix structure, and hair follicle regeneration

    Skin tumours of the anterior auricular concha are not uncommon. Wider excision and immediate reconstruction are required to reduce the risks of recurrence of the disease, cartilage infection and external ear distortion. Many surgical methods have been described for reconstruction of conchal defects. Post-auricular island flaps, such as the revolving-door (RD) flap, and full-thickness skin grafts (FTSGs) are the most-performed procedures. Although the RD flap has been fully described, it is not widely accepted and many surgeons, in their daily practice, prefer to use FTSG. It is a common experience that FTSGs are more subjected to centripetal contraction, decreasing the structural firmness of the conchal cavity and affecting functional and aesthetic outcomes. Furthermore, FTSGs are more prone to delay in wound healing due to the difficult access to this region that hinders adequate tie-over dressings. Between March 2003 and January 2007, 40 patients affected by T1 and T2 non-melanotic skin cancer and T1 melanoma of the anterior conchal surface of the external ear were included in a prospective study and randomly assigned to the RD reconstructed group or to the FTSG reconstructed group to investigate, compare and define advantages and disadvantages of both the techniques. Visual Analogue Scale (VAS) was used to evaluate the overall outcome and the colour and texture match. No flap or skin graft total loss was observed. Six patients (30%) showed partial failure of FTSG. The RD group demonstrated excellent cosmetic outcome, ideal colour match, adequate structure of external ear, projection and shape. Wilcoxon matched-pairs rank-sum test demonstrated statistically significant higher scores for the RD group compared to the FTSG group (p<0.0001). The RD harvesting technique is easy and quicker than the FTSG technique. RD flap should be considered as the first choice for reconstruction of anterior auricular conchal defects following wider excision of skin tumours

    The purpose of this study was to determine the value of magnetic resonance imaging (MRI) and ultrasound-based imaging strategies in the evaluation of a hypothetical population with a symptomatic full-thickness supraspinatus tendon (FTST) tear using formal cost-effectiveness analysis. A decision analytic model from the health care system perspective for 60-year-old patients with symptoms secondary to a suspected FTST tear was used to evaluate the incremental cost-effectiveness of 3 imaging strategies during a 2-year time horizon: MRI, ultrasound, and ultrasound followed by MRI. Comprehensive literature search and expert opinion provided data on cost, probability, and quality of life estimates. The primary effectiveness outcome was quality-adjusted life-years (QALYs) through 2 years, with a willingness-to-pay threshold set to $100,000/QALY gained (2016 U.S. dollars). Costs and health benefits were discounted at 3%. Ultrasound was the least costly strategy ($1385). MRI was the most effective (1.332 QALYs). Ultrasound was the most cost-effective strategy but was not dominant. The incremental cost-effectiveness ratio for MRI was $22,756/QALY gained, below the willingness-to-pay threshold. Two-way sensitivity analysis demonstrated that MRI was favored over the other imaging strategies over a wide range of reasonable costs. In probabilistic sensitivity analysis, MRI was the preferred imaging strategy in 78% of the simulations. MRI and ultrasound represent cost-effective imaging options for evaluation of the patient thought to have a symptomatic FTST tear. The results indicate that MRI is the preferred strategy based on cost-effectiveness criteria, although the decision between MRI and ultrasound for an imaging center is likely to be dependent on additional factors, such as available resources and workflow.

    Ionizing and near-infrared radiation are both part of the therapeutic spectrum in cancer treatment. During cancer therapy ionizing radiation is typically used for non-invasive reduction of malignant tissue, while near-infrared photobiomodulation is utilized in palliative medical approaches, e.g. for pain reduction or impairment of wound healing. Furthermore, near-infrared is part of the solar wavelength spectrum. A combined exposure of these two irradiation qualities - either intentionally during medical treatment or unintentionally due to solar exposure - is therefore presumable for cancer patients. Several studies in different model organisms and cell cultures show a strong impact of near-infrared pretreatment on ionizing radiation-induced stress response. To investigate the risks of non-thermal near-infrared (NIR) pretreatment in patients, a human in vitro full thickness skin models (FTSM) was evaluated for radiation research. FTSM were pretreated with therapy-relevant doses of NIR followed by X-radiation, and then examined for DNA-double-strand break (DSB) repair, cell proliferation and apoptosis. Double-treated FTSM revealed a clear influence of NIR on X-radiation-induced stress responses in cells in their typical tissue environment. Furthermore, over a 24h time period, double-treated FTSM presented a significant persistence of DSBs, as compared to samples exclusively irradiated by X-rays. In addition, NIR pretreatment inhibited apoptosis induction of integrated fibroblasts, and counteracted the radiation-induced proliferation inhibition of basal keratinocytes. Our work suggests that cancer patients treated with X-rays should be prevented from uncontrolled NIR irradiation. On the other hand, controlled double-treatment could provide an alternative therapy approach, exposing the patient to less radiation. Copyright © 2017. Published by Elsevier B.V.

    Objective: To observe the effects of arnebia root oil on wound healing of rats with full-thickness skin defect, and to explore the related mechanism. Methods: Eighty SD rats were divided into arnebia root oil group and control group according to the random number table, with 40 rats in each group, then full-thickness skin wounds with area of 3 cm×3 cm were inflicted on the back of each rat. Wounds of rats in arnebia root oil group and control group were treated with sterile medical gauze and bandage package infiltrated with arnebia root oil gauze or Vaseline gauze, respectively, with dressing change of once every two days. On post injury day (PID) 3, 7, 14, and 21, 10 rats in each group were sacrificed respectively for general observation and calculation of wound healing rate. The tissue samples of unhealed wound were collected for observation of histomorphological change with HE staining, observation of expressions of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) with immunohistochemical staining, and determination of mRNA expressions of VEGF and bFGF with real time fluorescent quantitive reverse transcription polymerase chain reaction. Data were processed with analysis of variance of factorial design, t test, and Bonferroni correction. Results: (1) On PID 3, there were a few secretions in wounds of rats in the two groups. On PID 7, there were fewer secretions and more granulation tissue in wounds of rats in arnebia root oil group, while there were more secretions and less granulation tissue in wounds of rats in control group. On PID 14, most of the wounds of rats in arnebia root oil group were healed and there was much red granulation tissue in unhealed wounds, while part of wounds of rats in control group was healed and there were a few secretions and less granulation tissue in unhealed wounds. On PID 21, wounds of rats in arnebia root oil group were basically healed, while there were still some unhealed wounds of rats in

    Synopsis Objective Retinoids are used as therapeutic agents for numerous skin diseases, for example, psoriasis, acne and keratinization disorders. The same substances have also been recognized in the treatment for hyperpigmentation disorders such as melasma. Other studies on photo-damaged skin have shown that retinoids reduce wrinkles, surface roughness, mottled pigmentation, and visual skin appearance as a whole. We tested the hypothesis that an organoculture of full-thickness human skin could be used as a preclinical model to investigate the retinoid transcriptional profile in human skin in vitro. Methods Full-thickness skin explants were exposed to topically applied all-trans retinoic acid (RA) for 24 h. The gene expression profile was analysed using oligonucleotide microarrays, and data were validated with real-time (RT) PCR. Results We showed that the expression of 93 genes was significantly altered more than twofold. Several of the altered genes, for example, KRT4, CYP26 and LCN2, have previously been shown to be affected by RA in keratinocyte monocultures, reconstructed epidermis and skin biopsies from patients treated topically or orally with RA. In addition, genes, such as SCEL, NRIP1, DGAT2, RDH12 EfnB2, MAPK14, SAMD9 and CEACAM6 not previously reported to be affected by RA in human skin, were identified for the first time in this study. Conclusion The results in the present study show that full-thickness human explants represent a valuable pre-clinical model for studying the effects of retinoids in skin.

    EPCs can be highly maintained and promoted by the CPB scaffold. Moreover, CPB/EPC constructs effectively stimulated the regeneration of diabetic wounds with satisfactory vascularization and better healing outcomes in a full-thickness wound model, suggesting that the highly efficient delivery of EPCs to wound site facilitates angiogenesis and further leads to wound healing. The high angiogenic capacity and excellent healing ability make CPB/EPC constructs highly competitive in cell-based therapeutic products for efficient wound repair application.

    We sought to evaluate the image quality of iterative reconstruction in image space (IRIS) in half-dose (HD) datasets compared with full-dose (FD) and HD filtered back projection (FBP) reconstruction in abdominal computed tomography (CT). To acquire data with FD and HD simultaneously, contrast-enhanced abdominal CT was performed with a dual-source CT system, both tubes operating at 120 kV, 100 ref.mAs, and pitch 0.8. Three different image datasets were reconstructed from the raw data: Standard FD images applying FBP which served as reference, HD images applying FBP and HD images applying IRIS. For the HD data sets, only data from 1 tube detector-system was used. Quantitative image quality analysis was performed by measuring image noise in tissue and air. Qualitative image quality was evaluated according to the European Guidelines on Quality criteria for CT. Additional assessment of artifacts, lesion conspicuity, and edge sharpness was performed. : Image noise in soft tissue was substantially decreased in HD-IRIS (-3.4 HU, -22%) and increased in HD-FBP (+6.2 HU, +39%) images when compared with the reference (mean noise, 15.9 HU). No significant differences between the FD-FBP and HD-IRIS images were found for the visually sharp anatomic reproduction, overall diagnostic acceptability (P = 0.923), lesion conspicuity (P = 0.592), and edge sharpness (P = 0.589), while HD-FBP was rated inferior. Streak artifacts and beam hardening was significantly more prominent in HD-FBP while HD-IRIS images exhibited a slightly different noise pattern. Direct intrapatient comparison of standard FD body protocols and HD-IRIS reconstruction suggest that the latest iterative reconstruction algorithms allow for approximately 50% dose reduction without deterioration of the high image quality necessary for confident diagnosis.

    Several observational studies have suggested the potential benefit of internal limiting membrane (ILM) peeling to treat idiopathic full-thickness macular hole (FTMH). However, no strong evidence is available on the potential benefit(s) of this surgical manoeuvre and uncertainty remains among vitreoretinal surgeons about the indication for peeling the ILM, whether to use it in all cases or in long-standing and/or larger holes.  To determine whether ILM peeling improves anatomical and functional outcomes of macular hole surgery compared with the no-peeling technique and to investigate the impact of different parameters such as presenting vision, stage/size of the hole and duration of symptoms in the success of the surgery. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) which contains the Cochrane Eyes and Vision Group Trials Register (The Cochrane Library 2013, Issue 2), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE, (January 1950 to February 2013), EMBASE (January 1980 to February 2013), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to February 2013), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We searched the reference lists of included studies for any additional studies not identified by the electronic searches. We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 28 February 2013.We searched reference lists of the studies included in the review for information about other studies on ILM peeling in macular hole surgery.

    A literature review of the first-, second- and third-generation autologous chondrocyte implantation (ACI) technique for the treatment of large-sized (>4 cm(2)) and full-thickness knee cartilage defects in young adults was conducted, examining the current literature on features, clinical scores, complications, magnetic resonance image (MRI) and histological outcomes, rehabilitation and cost-effectiveness. A literature review was carried out in the main medical databases to evaluate the several studies concerning ACI treatment of large-sized and full-thickness knee cartilage defects in young adults. ACI technique has been shown to relieve symptoms and improve functional assessment in large-sized (>4 cm(2)) and full-thickness knee articular cartilage defect of young adults in short- and medium-term follow-up. Besides, low level of evidence demonstrated its efficiency and durability at long-term follow-up after implantation. Furthermore, MRI and histological evaluations provided the evidence that graft can return back to the previous nearly normal cartilage via ACI techniques. Clinical outcomes tend to be similar in different ACI techniques, but with simplified procedure, low complication rate and better graft quality in the third-generation ACI technique. ACI based on the experience of cell-based therapy, with the high potential to regenerate hyaline-like tissue, represents clinical development in treatment of large-sized and full-thickness knee cartilage defects.

    Full Text Available Background Extensive degloving injuries of the extremities usually result in necrosis of the flap, necessitating comprehensive skin grafting. Provided there is a sufficient tool to evaluate flap viability, full-thickness skin can be used from a nonviable avulsed flap. We used a Wood's lamp to determine the viability of avulsed flaps in the operation field after intravenous injection of fluorescein dye. Methods We experienced 13 cases during 16 months. Fifteen minutes after the intravenous injection of fluorescein dye, the avulsed skin flaps were examined and non-fluorescent areas were marked under Wood's lamp illumination. The marked area was defatted for full-thickness skin grafting. The fluorescent areas were sutured directly without tension. The non-fluorescent areas were covered by defatted skin. Several days later, there was soft tissue necrosis within the flap area. We measured necrotic area and revised the flap. Results Among all the cases, necrotic area was 21.3% of the total avulsed area. However, if we exclude three cases, one of a carelessly managed patient and two cases of the flaps were inappropriately applied, good results were obtained, with a necrotic area of only 8.4%. Eight patients needed split-thickness skin grafts, and heel pad reconstruction was performed with free flap. Conclusions A full-thickness skin graft from an avulsed flap is a good method for addressing aesthetic concerns without producing donor site morbidity. Fluorescein dye is a useful, simple, and cost-effective tool for evaluating flap viability. Avulsed flap injuries can be managed well with Wood's lamp illumination and a full-thickness skin graft.

    Full text: There are numerous conditions that affect mainly or exclusively the pediatric population. These constitute true emergencies, related to patient's health. Delay in diagnosis and treatment of abdominal non-traumatic emergencies may result in rapid deterioration, peritonitis, sepsis, even death or in severe complications with subsequent morbidity. Abdominal emergencies in children mostly present with pain, tenderness, occasionally coupled by vomiting, fever, abdominal distension, and failure to pass meconium or stools. Diarrhea, blood per rectum, abnormal laboratory tests and lethargy may also be manifestations of acute abdominal conditions. Abdominal emergencies have a different aetiology, depending on age and whether the pain is acute or chronic. Symptoms have to be matched with age and gender. Newborns up to 1 months of age may have congenital diseases: atresia, low obstruction including Hirschsprung's disease, meconium ileus. Meconium plug is one of the commonest cause of low obstruction in newborns that may also develop necrotizing enterocolitis, incarcerated inguinal hernia and mid-gut volvulus. Past the immediate postnatal period, any duodenal obstruction should be considered midgut volvulus until proven otherwise and patients should undergo ultrasonography and/or properly performed upper GI contrast study that records the exact position of the deduno-jejunal junction. Infants 6 months-2 years carry the risk of intussusception, mid-gut volvulus, perforation, acute pyelonephritis. Preschool and school-aged children 2-12 years carry the risk of appendicitis, genito-urinary abnormalities including torsion, urachal abnormalities, haemolytic uremic syndrome and Henoch-Schonlein purpura. Children above 12 years suffer from the same conditions as in adults. Most conditions may affect any age despite age predilection. Abdominal solid organ ultrasonography (US) coupled with gastrointestinal ultrasonography is the principle imaging modality in radiosensitive

  11. Full-Thickness Skin Grafting with De-Epithelization of the Wound Margin for Finger Defects with Bone or Tendon Exposure

    2015-05-01

    Full Text Available BackgroundFull-thickness skin grafts (FTSGs are generally considered unreliable for coverage of full-thickness finger defects with bone or tendon exposure, and there are few clinical reports of its use in this context. However, animal studies have shown that an FTSG can survive over an avascular area ranging up to 12 mm in diameter. In our experience, the width of the exposed bones or tendons in full-thickness finger defects is <7 mm. Therefore, we covered the bone- or tendon-exposed defects of 16 fingers of 10 patients with FTSGs.MethodsThe surgical objectives were healthy granulation tissue formation in the wound bed, marginal de-epithelization of the normal skin surrounding the defect, preservation of the subdermal plexus of the central graft, and partial excision of the dermis along the graft margin. The donor site was the mastoid for small defects and the groin for large defects.ResultsMost of the grafts (15 of 16 fingers survived without significant surgical complications and achieved satisfactory functional and aesthetic results. Minor complications included partial graft loss in one patient, a minimal extension deformity in two patients, a depression deformity in one patient, and mild hyperpigmentation in four patients.ConclusionsWe observed excellent graft survival with this method with no additional surgical injury of the normal finger, satisfactory functional and aesthetic outcomes, and no need for secondary debulking procedures. Potential disadvantages include an insufficient volume of soft tissue and graft hyperpigmentation. Therefore, FTSGs may be an option for treatment of full-thickness finger defects with bone or tendon exposure.

  12. Cultivation of Keratinocytes and Fibroblasts in a Three-Dimensional Bovine Collagen-Elastin Matrix (Matriderm® and Application for Full Thickness Wound Coverage in Vivo

    2013-07-01

    Full Text Available New skin substitutes for burn medicine or reconstructive surgery pose an important issue in plastic surgery. Matriderm® is a clinically approved three-dimensional bovine collagen-elastin matrix which is already used as a dermal substitute of full thickness burn wounds. The drawback of an avital matrix is the limited integration in full thickness skin defects, depending on the defect size. To further optimize this process, Matriderm® has also been studied as a matrix for tissue engineering of skin albeit long-term cultivation of the matrix with cells has been difficult. Cells have generally been seeded onto the matrix with high cell loss and minimal time-consuming migration. Here we developed a cell seeded skin equivalent after microtransfer of cells directly into the matrix. First, cells were cultured, and microinjected into Matriderm®. Then, cell viability in the matrix was determined by histology in vitro. As a next step, the skin substitute was applied in vivo into a full thickness rodent wound model. The wound coverage and healing was observed over a period of two weeks followed by histological examination assessing cell viability, proliferation and integration into the host. Viable and proliferating cells could be found throughout the entire matrix. The presented skin substitute resembles healthy skin in morphology and integrity. Based on this study, future investigations are planned to examine behaviour of epidermal stem cells injected into a collagen-elastin matrix under the aspects of establishment of stem cell niches and differentiation.

    Burns of the first commissure of the hand can evolve into an adduction contracture of the thumb. We decided to conduct a review of the existing literature on the treatment of full-thickness burns of the first commissure in order to develop a treatment algorithm that integrates the various currently available procedures. A search of the existing literature was conducted, focusing on the treatment of a burn of the first commissure in its chronic and acute phases. A total of 29 relevant articles were selected; 24 focused exclusively on the chronic contracture stage, while 3 focused exclusively on the acute burn stage, and 2 articles studied both stages. A therapeutic algorithm for full-thickness burns of the first commissure of the hand was developed. With this algorithm we sought to relate each degree and stage of the burn with a treatment.

    Tooth extraction is considered as the starting point of jaw atrophy via osteoclast activity stimulation. The maintenance of dental alveolar bone depends on surgery procedure and use of materials to maintain prior space favoring bone regeneration. Among substitutes used in dentistry to fill bone defects, Ostim-Pastes (Ostim) is a nanocrystalline paste tested for treatment of severe clinical conditions. This research first investigated the effect of Ostim on alveolar healing, comparing in the same healthy subjects, an Ostim-filled socket with a not-filled one. Moreover, it also proposed a new surgical protocol for the post-extractive socket treatment using the graft materials without elevation of full-thickness flaps. Fourteen patients were enrolled to bilateral maxillary or mandibular extraction that was performed without elevation of full-thickness flaps. In each patient, one socket was filled using Ostim, and the other one was allowed to undergo natural healing. No suture was carried out. Clinical and biologic parameters were screened at 1, 7, and 14 days. Obtained results evidenced that nanocrystalline hydroxyapatite supports bone regeneration, increasing the synthesis of pro-osteogenic factors as bone morphogenetics protein (BMP)-4, BMP-7, alkaline phosphatase, and osteocalcin. Moreover, filling post-extractive socket with nanocrystalline hydroxyapatite paste leads to a complete epithelialization already at 7 days after extraction, despite the fact that the teeth were extracted without elevation of full-thickness flaps . The improved epithelialization is mediated by increased vascular endothelial growth factor (VEGF) expression. No significant change was observed in inflammatory parameters, with exception of an early and transient IL-1β induction, that could trigger and improve alveolar healing. Clinical and biomolecular observations of this explorative study evidenced that nanocrystalline hydroxyapatite improves alveolar socket healing, increasing angiogenesis

    A novel product, the fish skin acellular dermal matrix (ADM) has recently been introduced into the family of biological materials for the treatment of wounds. Hitherto, these products have been produced from the organs of livestock. A noninferiority test was used to compare the effect of fish skin ADM against porcine small-intestine submucosa extracellular matrix in the healing of 162 full-thickness 4-mm wounds on the forearm of 81 volunteers. The fish skin product was noninferior at the primary end point, healing at 28 days. Furthermore, the wounds treated with fish skin acellular matrix healed significantly faster. These results might give the fish skin ADM an advantage because of its environmental neutrality when compared with livestock-derived products. The study results on these acute full-thickness wounds might apply for diabetic foot ulcers and other chronic full-thickness wounds, and the shorter healing time for the fish skin-treated group could influence treatment decisions. To test the autoimmune reactivity of the fish skin, the participants were tested with the following ELISA (enzyme-linked immunosorbent assay) tests: RF, ANA, ENA, anti ds-DNA, ANCA, anti-CCP, and anticollagen I and II. These showed no reactivity. The results demonstrate the claims of safety and efficacy of fish skin ADM for wound care. © The Author(s) 2015.

    To better define the prevalence and location of full-thickness articular cartilage lesions in elite football players undergoing knee magnetic resonance imaging (MRI) at the National Football League (NFL) Invitational Combine and assess the association of these lesions with previous knee surgery. We performed a retrospective review of all participants in the NFL Combine undergoing a knee MRI scan from 2005 to 2009. Each MRI scan was reviewed for evidence of articular cartilage disease. History of previous knee surgery including anterior cruciate ligament reconstruction, meniscal procedures, and articular cartilage surgery was recorded for each athlete. Knees with a history of previous articular cartilage restoration surgery were excluded from the analysis. A total of 704 knee MRI scans were included in the analysis. Full-thickness articular cartilage lesions were associated with a history of any previous knee surgery (P football players at the NFL Combine undergoing MRI. The lateral compartment appears to be at greater risk for full-thickness cartilage loss. Previous knee surgery, particularly meniscectomy, is associated with these lesions.

    Sulfur mustard is a potent vesicant that induces inflammation, edema and blistering following dermal exposure. To assess molecular mechanisms mediating these responses, we analyzed the effects of the model sulfur mustard vesicant, 2-chloroethyl ethyl sulfide, on EpiDerm-FT TM , a commercially available full-thickness human skin equivalent. CEES (100-1000 μM) caused a concentration-dependent increase in pyknotic nuclei and vacuolization in basal keratinocytes; at high concentrations (300-1000 μM), CEES also disrupted keratin filament architecture in the stratum corneum. This was associated with time-dependent increases in expression of proliferating cell nuclear antigen, a marker of cell proliferation, and poly(ADP-ribose) polymerase (PARP) and phosphorylated histone H2AX, markers of DNA damage. Concentration- and time-dependent increases in mRNA and protein expression of eicosanoid biosynthetic enzymes including COX-2, 5-lipoxygenase, microsomal PGE 2 synthases, leukotriene (LT) A 4 hydrolase and LTC 4 synthase were observed in CEES-treated skin equivalents, as well as in antioxidant enzymes, glutathione S-transferases A1-2 (GSTA1-2), GSTA3 and GSTA4. These data demonstrate that CEES induces rapid cellular damage, cytotoxicity and inflammation in full-thickness skin equivalents. These effects are similar to human responses to vesicants in vivo and suggest that the full thickness skin equivalent is a useful in vitro model to characterize the biological effects of mustards and to develop potential therapeutics.

    Full Text Available Purpose: To report a case of macular hole closure after the exchange of a silicone-oil tamponade with gas C3F8 14%. Method: A 64-year-old female patient with a stage IV macular hole underwent a three-port pars-plana vitrectomy and internal limiting membrane peeling. Due to the patient’s chronic illness (respiratory problems, a silicone-oil tamponade was preferred. However, the macula hole was still flat opened four months postoperatively. Therefore, the patient underwent an exchange of silicone oil with gas C3F8 14%. No face-down position was advised postoperatively due to her health problems. Results: Macular hole closure was confirmed with optical coherence tomography six weeks after exchanging the silicone oil with gas. Conclusions: Macular hole surgery using a silicone-oil tamponade has been proposed as treatment of choice for patients unable to posture. In our case, the use of a long-acting gas (C3F8 14%, even without posturing, proved to be more effective.

    2012-07-01

    Full Text Available Abstract Introduction Fentanyl transdermal patches have been widely used in the treatment of chronic pain and in palliative care settings since 1991 in cases where prolonged opioid use is often necessary. Transdermal drug delivery is deemed safe and effective with the advantages of delivering a steady dose of the drug and improving patient compliance due to its ease of use. However, intentional and unintentional misuse and overdose using transdermal opioid patches has been widely reported in the literature. Case presentation We describe the case of a 77-year-old Caucasian woman who developed severe opioid toxicity while sun tanning, likely due to altered fentanyl transdermal patch function in a heated environment. As a result of prolonged sun exposure due to an opioid-induced coma she then sustained hyperthermia and severe burns to her abdomen and lower limbs. This inadvertent fentanyl overdose necessitated initial treatment in intensive care and follow on care in a specialist burn unit. Conclusion Patients who are using fentanyl patches and their relatives should be educated about how to use the patch safely. Healthcare practitioners should warn patients about the possibility of overdosing on transdermally delivered drugs if used incorrectly. They should avoid strenuous activities and external heat sources such as warming blankets, hot water bottles, saunas, hot tubs or sunbathing and should seek medical attention if they develop a fever. Additionally, any burns sustained in the context of altered consciousness levels such as in this case with opioid overdose should raise suspicion about a potential deeper burn injury than is usually observed.

    To evaluate repair tissue (RT) after microfracture treatment for full-thickness cartilage defect models using quantitative MRI and investigate the correlations between MRI and histological findings. The animal experiment was approved by the Animal Care and Use Committee of our college. Thirty-six full-thickness cartilage defect models in rabbit knee joints were assigned to the microfracture or joint debridement group (as control). Each group consisted of 3-week, 5-week, and 7-week subgroups. MR imaging, including a three-dimensional double-echo steady-state sequence (3D-DESS), and T2 mapping were performed at 3, 5, and 7 weeks postoperatively. The thickness and T2 indices of RT were calculated. After MRI scans at each time point, operation sites were removed to make hematoxylin-eosin (H and E)-stained sections. Histological results were evaluated using the modified O'Driscoll score system. Comparisons were made between the two groups with respect to the MRI and histological findings, and correlation analysis was performed within each group. The thickness index and histological O'Driscoll score of RT in the two groups increased over time, while the T2 index decreased. The thickness index and histological O'Driscoll score of the microfracture group were higher than in the joint debridement group at each time point. The T2 index of the microfracture group was lower than in the joint debridement group at 3 weeks (P = 0.006), while it was higher than in the joint debridement group at 5 and 7 weeks (P = 0.025 and 0.025). The thickness index was positively correlated with the histological O'Driscoll score in both groups (microfracture: r s = 0.745, P s = 0.680, P = 0.002). The T2 index was negatively correlated with the histological O'Driscoll score in both groups (microfracture: r s = -0.715, P = 0.002; joint debridement: r s = -0.826, P < 0.001). Significant improvement over time after microfracture can be expected on the basis of the quantitative MRI finding and

    To evaluate repair tissue (RT) after microfracture treatment for full-thickness cartilage defect models using quantitative MRI and investigate the correlations between MRI and histological findings. The animal experiment was approved by the Animal Care and Use Committee of our college. Thirty-six full-thickness cartilage defect models in rabbit knee joints were assigned to the microfracture or joint debridement group (as control). Each group consisted of 3-week, 5-week, and 7-week subgroups. MR imaging, including a three-dimensional double-echo steady-state sequence (3D-DESS), and T2 mapping were performed at 3, 5, and 7 weeks postoperatively. The thickness and T2 indices of RT were calculated. After MRI scans at each time point, operation sites were removed to make hematoxylin-eosin (H and E)-stained sections. Histological results were evaluated using the modified O'Driscoll score system. Comparisons were made between the two groups with respect to the MRI and histological findings, and correlation analysis was performed within each group. The thickness index and histological O'Driscoll score of RT in the two groups increased over time, while the T2 index decreased. The thickness index and histological O'Driscoll score of the microfracture group were higher than in the joint debridement group at each time point. The T2 index of the microfracture group was lower than in the joint debridement group at 3 weeks (P = 0.006), while it was higher than in the joint debridement group at 5 and 7 weeks (P = 0.025 and 0.025). The thickness index was positively correlated with the histological O'Driscoll score in both groups (microfracture: r{sub s} = 0.745, P < 0.001; joint debridement: r{sub s} = 0.680, P = 0.002). The T2 index was negatively correlated with the histological O'Driscoll score in both groups (microfracture: r{sub s} = -0.715, P = 0.002; joint debridement: r{sub s} = -0.826, P < 0.001).

    The simultaneous application of ultrasound and the surfactant sodium lauryl sulfate (referred to as US/SLS) to skin enhances transdermal drug delivery (TDD) in a synergistic mechanical and chemical manner. Since full-thickness skin (FTS) and split-thickness skin (STS) differ in mechanical strength, US/SLS treatment may have different effects on their transdermal transport pathways. Therefore, we evaluated STS as an alternative to the well-established US/SLS-treated FTS model for TDD studies of hydrophilic permeants. We utilized the aqueous porous pathway model to compare the effects of US/SLS treatment on the skin permeability and the pore radius of pig and human FTS and STS over a range of skin electrical resistivity values. Our findings indicate that the US/SLS-treated pig skin models exhibit similar permeabilities and pore radii, but the human skin models do not. Furthermore, the US/SLS-enhanced delivery of gold nanoparticles and quantum dots (two model hydrophilic macromolecules) is greater through pig STS than through pig FTS, due to the presence of less dermis that acts as an artificial barrier to macromolecules. In spite of greater variability in correlations between STS permeability and resistivity, our findings strongly suggest the use of 700microm-thick pig STS to investigate the in vitro US/SLS-enhanced delivery of hydrophilic macromolecules. 2010 Elsevier B.V.

    Full Text Available Objective: In our study, we evaluated the post-operative 5-year clinical and radiological results and the ratio of re­current ruptures under magnetic resonance imaging of the patients diagnosed as wide and massive, full-thick­ness rotator cuff rupture and arthroscopic-assisted mini-open rotator cuff repair is applied. Methods: We evaluated the pre-operative and post-op­erative clinical and radiological results of 38 patients with wide and massive, full-thickness rotator cuff rupture and arthroscopic-assisted rotator cuff repair is applied after failure of conservative treatment. Results: Mean post-operative follow-up period was 60.4 months. According to UCLA scoring there were excellent results in 26 patients, good results in 10, and moderate results in 2 patients. According to Constant scoring there were excellent results in 24 patients, good results in 12, and moderate results in 2 patients. 34 of the 38 patients indicated that they were satisfied with the results. The continuity of the rotator cuffs are evaluated with magnetic resonance imaging at the last visits of the patients and there was recurrent ruptures at the 8 patients. Conclusion: Although recurrent rotator cuff rupture rates varies depending on the age of the patients, moderate clinical results are obtained in elder patients. Neverthe­less, despite the rupture rates in the treatment of wide and massive, full-thickness ruptures, satisfactory clinical results can be obtained with arthroscopic-assisted mini-open rotator cuff repair.

Aim: To develop a test for subjective evaluation of visual distortion in the central visual field around fixation in patients with unilateral FTMH or ERM. Settings and Design: Prospective case-control study carried out at tertiary referral center. Materials and Methods: Twenty-five patients with unilateral macular disease (13 macular epiretinal membranes, 12 full-thickness macular holes, and nine controls (without ocular pathology underwent ophthalmological examination with logMAR ETDRS visual acuity, near vision and contrast sensitivity assessed. Macular optical coherence tomography and metamorphopsia assessment using Morphision test was also carried out. This test consists of a set of modified Amsler charts for detection, identification, and subjective quantification of visual distortion in the central visual field around fixation. Morphision test content and construct validity, and reliability (test-retest method were evaluated. Sixteen patients completed an unstructured survey on test performance and preference. Results: Every patient with unilateral FTMH or ERM identified a particular chart using Morphision test (content validity. None of the normal subjects without symptoms of metamorphopsia identified any distortion (construct validity. Test-retest showed a 100% consistency for frequency and 67% for amplitude. The mean amplitude difference between measurements was 0.02 degrees (SD = 0.038. The coefficient of repeatability was 0.075. There was a correlation between Morphision amplitude score and visual acuity and contrast sensitivity, individually. Conclusions: Morphision test allowed detection and subjective quantification of metamorphopsia in the clinical setting in our patients with unilateral macular epiretinal membranes and full thickness macular holes.

    To investigate the effects of different doses of insulin-like growth factor 1 (IGF-1) on the cartilage layer and subchondral bone (SB) during repair of full-thickness articular cartilage (AC) defects. IGF-1-loaded collagen membrane was implanted into full-thickness AC defects in rabbits. The effects of two different doses of IGF-1 on cartilage layer and SB adjacent to the defect, the cartilage structure, formation and integration, and the new SB formation were evaluated at the 1st, 4th and 8th week postoperation. Meanwhile, after 1 week treatment, the relative mRNA expressions in tissues adjacent to the defect, including cartilage and SB were determined by quantitative real-time RT-PCR (qRT-PCR), respectively. Different doses of IGF-1 induced different gene expression profiles in tissues adjacent to the defect and resulted in different repair outcomes. Particularly, at high dose IGF-1 aided cell survival, regulated the gene expressions in cartilage layer adjacent defect and altered ECM composition more effectively, improved the formation and integrity of neo-cartilage. While, at low dose IGF-1 regulated the gene expressions in SB more efficaciously and subsequently promoted the SB remodeling and reconstruction. Different doses of IGF-1 induced different responses of cartilage or SB during the repair of full-thickness AC defects. Particularly, high dose of IGF-1 was more beneficial to the neo-cartilage formation and integration, while low dose of it was more effective for the SB formation.

    Full Text Available Tissue engineering (TE has been proven usefulness in cartilage defect repair. For effective cartilage repair, the structural orientation of the cartilage scaffold should mimic that of native articular cartilage, as this orientation is closely linked to cartilage mechanical functions. Using thermal-induced phase separation (TIPS technology, we have fabricated an oriented cartilage extracellular matrix (ECM-derived scaffold with a Young's modulus value 3 times higher than that of a random scaffold. In this study, we test the effectiveness of bone mesenchymal stem cell (BMSC-scaffold constructs (cell-oriented and random in repairing full-thickness articular cartilage defects in rabbits. While histological and immunohistochemical analyses revealed efficient cartilage regeneration and cartilaginous matrix secretion at 6 and 12 weeks after transplantation in both groups, the biochemical properties (levels of DNA, GAG, and collagen and biomechanical values in the oriented scaffold group were higher than that in random group at early time points after implantation. While these differences were not evident at 24 weeks, the biochemical and biomechanical properties of the regenerated cartilage in the oriented scaffold-BMSC construct group were similar to that of native cartilage. These results demonstrate that an oriented scaffold, in combination with differentiated BMSCs can successfully repair full-thickness articular cartilage defects in rabbits, and produce cartilage enhanced biomechanical properties.

    Full Text Available In order to investigate and evaluate the effects of red deer antlers on hair growth in the full-thickness wound healing model, Sprague-Dawley rats were given incision wounds through the full thickness of their dorsal skin and deer antler was applied for 40 days. At specified intervals thereafter (4, 8, 16, 32 and 40 days, the animals were sacrificed and the wound site skins were excised, processed, and sectioned. At post-injury days 16, 32 and 40, longer and more active new hair appeared around the healing wound of antler-treated skin. Histological studies showed that the antler extract markedly increases the depth, size, and number of hair follicles. Expression of IGF-I (insulin-like growth factor mRNA was detected by RT-PCR and real time RT-PCR. The result showed that the expression of IGF-I (days 16, 32, and 40 was obviously up-regulated in antler-treated skins compared to control skins. Similar results were seen in the ELISA analysis to quantify the IGF-I expression. These results support the notion that wound healing can cause hair growth by enhancing the expression of IGF-I. Deer antler extract appears to have the potential to promote hair growth and could be used in hair growth products.

    Full Text Available Early repair of skin injury and maximal restoration of the function and appearance have become important targets of clinical treatment. In the present study, we observed the healing process of skin defects in nude mice and structural characteristics of the new skin after transplantation of isolated and cultured adipose derived mesenchymal stem cells (ADMSCs onto the human acellular amniotic membrane (AAM. The result showed that ADMSCs were closely attached to the surface of AAM and grew well 24 h after seeding. Comparison of the wound healing rate at days 7, 14, and 28 after transplantation showed that ADMSCs seeded on AAM facilitated the healing of full-thickness skin wounds more effectively as compared with either hAM or AAM alone, indicating that ADMSCs participated in skin regeneration. More importantly, we noticed a phenomenon of hair follicle development during the process of skin repair. Composite ADMSCs and AAM not only promoted the healing of the mouse full-thickness defects but also facilitated generation of the appendages of the affected skin, thus promoting restoration of the skin function. Our results provide a new possible therapy idea for the treatment of skin wounds with respect to both anatomical regeneration and functional restoration.

    Full-thickness skin defects represent a significant and urgent clinical problem. Dermal substitutes serving as a regenerative template to induce dermal reconstruction provide a promising method to treat serious skin defects. Although collagen-chitosan dermal scaffolds display good biocompatibility and a suitable porous structure for angiogenesis and tissue regeneration, their poor mechanical properties compromise their application. To develop a well-supported dermal substitute, a poly(l-lactide-co-glycolide) (PLGA) knitted mesh was fabricated and integrated with collagen-chitosan scaffold (CCS) to obtain a PLGA knitted mesh-reinforced CCS (PLGAm/CCS). The morphology of this PLGAm/CCS was investigated in vitro. To characterize the tissue response, specifically angiogenesis and tissue regeneration, the PLGAm/CCS was transplanted in combination with thin split-thickness autografts to repair full-thickness skin wounds using a one-step surgical procedure in Sprague-Dawley rats. These results were then compared with CCSs. At weeks 2, 4 and 8 after the operation, the healing wounds were imaged to analyse wound changes, and tissue specimens were harvested for histology, immunohistochemistry, real-time quantitative polymerase chain reaction and Western blot analysis. The results demonstrated that collagen-chitosan sponge in the PLGAm/CCS remained porous, interconnected and occupied the openings of PLGA mesh, and the incorporation of the PLGA knitted mesh into CCS improved the mechanical strength with little influence on its mean pore size and porosity. Following transplantation, PLGAm/CCS inhibited wound contraction, and effectively promoted neotissue formation and blood vessel ingrowth. In conclusion, the mechanical strength of the scaffolds plays an important role in the process of tissue regeneration and vascularization. The ability of PLGAm/CCS to promote angiogenesis and induce in situ tissue regeneration demonstrates its potential in skin tissue engineering. Copyright

    Full Text Available Painful callosities of the feet (PCOF are a rare complaint in children with severe impairment of mobility and quality of life. There is no medical treatment available.We investigated the usefulness of a recently developed combined transplant technique-the sandwich transplantation with dermal collagen-elastin template in this rare condition. A 14-year-old boy suffered from PCOF for several years without any improvement by topical therapy, dermabrasion, and oral retinoids. He was unable to walk normally and suffered from severe pain. We performed a complete deep excision of the hyperkeratotic plantar tissue in general anaesthesia in combination with sandwich transplantation in the same setting. Dry sheets of collagen-elastin matrix (1 mm thickness were placed on the soft tissue defects and covered by full-thickness mesh graft transplants from the upper leg. An individualized orthosis was produced for gait rehabilitation. Two weeks after surgery the gait-related pain was reduced remarkably. Using the orthosis, the boy was able to walk pain-free even on staircase. Surgery of PCOF with sandwich transplantation and gait rehabilitation appears to be a promising strategy for this rare condition.

    Nontraumatic full-thickness rotator cuff tears are commonly initially treated conservatively. If conservative treatment fails, rotator cuff repair is a viable subsequent option. The objective of the present meta-analysis is to evaluate the shoulder-specific outcomes one year after arthroscopic or mini-open rotator cuff repair of nontraumatic rotator cuff tears. A literature search was conducted in PubMed and EMBASE within the period January 2000 to January 2017. All studies measuring the clinical outcome at 12 months after nontraumatic rotator cuff repair of full-thickness rotator cuff tears were listed. We included 16 randomized controlled trials that met our inclusion criteria with a total of 1.221 shoulders. At 12 months after rotator cuff repair, the mean Constant score had increased 29.5 points; the mean American Shoulder and Elbow Score score increased by 38.6 points; mean Simple Shoulder Test score was 5.6 points; mean University of California Los Angeles score improved by 13.0 points; and finally, mean Visual Analogue Scale score decreased by 4.1 points. Based on this meta-analysis, significant improvements in the shoulder-specific indices are observed 12 months after nontraumatic arthroscopic or mini-open rotator cuff repair.

    Experimental X-ray injuries of the skin were created on guineapigs with contact therapy conditions with a total dose of 14,000 or 12,000R. Measurements of the skin temperature and heat release of the skin show that regardless of whether the donor or recipient site was injured, a reproduction of the plethora and a reduction of the blood circulation of antologous, free full thickness skin grafts was brought about compared to control grafts if the operation was performed 2 - 3 weeks after ending irradiation. Extensively corresponding results were obtained if the operation was performed 5 months after terminating irradiation; however, an increased blood circulation was detected on the 7th post-operative day with the pre-injury of the graft bed. Corresponding measurements on 10 human full thickness skin grafts with radiation-injured graft bed and 15 comparison grafts also showed a negative influence of the revascularisation by the X-ray injury of the graft bed.

    Recent introduction of rapid bromelain-based enzymatic debridement has been increasingly popular in its use in non-surgical debridement in deep partial and full thickness burns. We designed this study to evaluate the evidence suggested by current studies on the perceived benefits of using Nexobrid® as compared to traditional surgical standard of care (SOC) in burns wound debridement. A comprehensive search on electronic databases Pubmed, Embase and Web of Science was done to identify studies published between 1986 to 2017 involving the use of Nexobrid in deep partial and full thickness burns. Studies were evaluated for proposed benefits and categorised under supporting evidence, contradicting evidence and anecdotal opinions. 7 well designed prospective studies met the inclusion comprising of 4 randomised controlled trials. 6 proposed benefits associated with the use of Nexobrid were extracted including reduced time to complete debridement, need for surgery, area of burns excised, need for autograft, time to wound closure and improved scar quality. Most proposed benefits have strong supporting evidences with minimal anecdotal opinions from controlled trials except the proposed improvement in scar quality and reduced time to wound healing that had at least 3 refuting evidence and 1 anecdotal evidence. Incidence of pain was also evaluated and were mainly anecdotal lacking formal objective assessment or cohort study. Despite the lack of literatures available, the benefits of Nexobrid is evident in published randomised and single arm studies. Large number of studies are needed to aid further evaluating the proposed benefits of Nexobrid.

    Full Text Available The osteochondral healing potential of hyaluronic acid (HA plus diacerein was evaluated in subchondral-drilling- (SCD- induced fibrocartilage generation in rabbits. A full-thickness chondral defect was created along the patellar groove of both knees and then SCD was subsequently performed only in the left knee. A week later, the rabbits were allocated into 3 groups to receive weekly intra-articular (IA injection for 5 weeks with normal saline solution (NSS (group 1 or with HA (group 2 and group 3. Starting at the first IA injection, rabbits were also gavaged daily for 9 weeks with NSS (group 1 and group 2 or with diacerein (group 3. The animals were then sacrificed for evaluation. The newly formed tissue in SCD lesions showed significantly better histological grading scale and had higher content of type II collagen in HA-treated group compared to NSS control. In addition, adding oral diacerein to HA injection enhanced healing potential of HA.

    Background: In daily practice, we discovered one of the secondary magnetic resonance (MR) findings of the subscapularis (SSC) tendon tear, the 'bridging sign', which has not been previously described. Purpose: To describe the 'bridging sign' on shoulder MR imaging and its radiological and clinical significance in patients with SSC tendon tear. Material and Methods: Twenty-nine patients who had undergone shoulder arthroscopy and had full-thickness tear of the subscapularis tendon were enrolled. The medical records of the 29 patients were retrospectively reviewed for the duration of shoulder pain, rotator cuff tears, and associated arthroscopic findings: biceps tendon abnormality and superior glenoid labral tear. Then, preoperative shoulder MR images were retrospectively reviewed for the presence or absence of the 'bridging sign' and associated MR findings: periarticular fluid and fatty atrophy of the supraspinatus and subscapularis muscles. The type of rotator cuff tear associated with the 'bridging sign' was assessed and the sensitivity, specificity, and accuracy of the 'bridging sign' for the diagnosis of a certain type of rotator cuff tear were calculated. Associated arthroscopic and MR findings and mean duration of the shoulder pain between the patients with and without the 'bridging sign' were compared. Results: The 'bridging sign' was seen in 17 of 29 patients and corresponded to a complex of the torn and superomedially retracted subscapularis tendon, coracohumeral ligament, and superior glenohumeral ligament, adhered to the anterior margin of the torn supraspinatus (SSP) tendon on arthroscopy. All patients with the 'bridging sign' had combined full-thickness tear (FTT) of the cranial 1/2 portion of the subscapularis tendon and anterior 1/2 portion of the SSP tendon.

    Cell therapy is an emerging therapeutic strategy aimed at replacing or repairing severely damaged tissues with cultured cells. Epidermal regeneration obtained with autologous cultured keratinocytes (cultured autografts) can be life-saving for patients suffering from massive full-thickness burns. However, the widespread use of cultured autografts has been hampered by poor clinical results that have been consistently reported by different burn units, even when cells were applied on properly prepared wound beds. This might arise from the depletion of epidermal stem cells (holoclones) in culture. Depletion of holoclones can occur because of (i) incorrect culture conditions, (ii) environmental damage of the exposed basal layer of cultured grafts, or (iii) use of new substrates or culture technologies not pretested for holoclone preservation. The aim of this study was to show that, if new keratinocyte culture technologies and/or "delivery systems" are proposed, a careful evaluation of epidermal stem cell preservation is essential for the clinical performance of this life-saving technology. Fibrin was chosen as a potential substrate for keratinocyte cultivation. Stem cells were monitored by clonal analysis using the culture system originally described by Rheinwald and Green as a reference. Massive full-thickness burns were treated with the composite allodermis/cultured autograft technique. We show that: (i) the relative percentage of holoclones, meroclones, and paraclones is maintained when keratinocytes are cultivated on fibrin, proving that fibrin does not induce clonal conversion and consequent loss of epidermal stem cells; (ii) the clonogenic ability, growth rate, and long-term proliferative potential are not affected by the new culture system; (iii) when fibrin-cultured autografts bearing stem cells are applied on massive full-thickness burns, the "take" of keratinocytes is high, reproducible, and permanent; and (iv) fibrin allows a significant reduction of the cost

    This retrospective study compared the clinical and radiologic outcomes of patients who underwent arthroscopic rotator cuff repairs by the suture-bridge and double-row modified Mason-Allen techniques. From January 2012 to May 2013, 76 consecutive cases of full-thickness rotator cuff tear, 1 to 4 cm in the sagittal plane, for which arthroscopic rotator cuff repair was performed, were included. The suture-bridge technique was used in 37 consecutive shoulders; and the double-row modified Mason-Allen technique, in 39 consecutive shoulders. Clinical outcomes at a minimum of 2 years (mean, 35.7 months) were evaluated postoperatively using the visual analog scale; University of California, Los Angeles Shoulder Scale; American Shoulder and Elbow Surgeons Subjective Shoulder Scale; and Constant score. Postoperative cuff integrity was evaluated at a mean of 17.7 months by magnetic resonance imaging. At the final follow-up, the clinical outcomes improved in both groups (all P  .05). The retear rate was 18.9% in the shoulders subjected to suture-bridge repair and 12.8% in the double-row modified Mason-Allen group; the difference was not significant (P = .361). Despite the presence of fewer suture anchors, the patients who underwent double-row modified Mason-Allen repair had comparable shoulder functional outcomes and a comparable retear rate with those who underwent suture-bridge repair. Therefore, the double-row modified Mason-Allen repair technique can be considered an effective treatment for patients with medium- to large-sized full-thickness rotator cuff tears.

    The aim of this study was to investigate whether topical application of fibrin-binding oligopeptides derived from FN promotes wound healing in streptozotocin (STZ)-induced diabetic rats. Oligopeptides including fibrin-binding sequences (FF3: CFDKYTGNTYRV, FF5 : CTSRNRCNDQ) of FN repeats were synthesized. Each peptide was loaded in 15 x 15 mm fibrous alginate dressings, and the release kinetics of the peptides was evaluated using trinitrobenzene sulfonic acid for 336 hours. Two full-thickness cutaneous wounds were prepared on the dorsal skin of each 75 diabetes induced rats. Each wound was divided into FF3-loaded alginate dressing group, FF5-loaded alginate dressing group, alginate dressing group and negative control group. Animals were sacrificed at day 0,3,7 and 14. The wound closure rate, inflammation degree, expression of TGF-β1 and hydroxyproline contents were evaluated. Both FF3 and FF5 peptides were released rapidly within the first 24 hours. FF3-loaded dressing treated wounds closed significantly faster than other wounds at day 3. And at day 14, FF3- & FF5- loaded dressing treated wounds demonstrated less inflammatory cells infiltration than alginate dressing treated and negative group wounds. TGF-β1 positive cells were more abundant in FF3-, FF5-treated alginate dressing treated wound at day 3 and 14. At last, the hyrdroxyproline contents in the FF3, FF5 group were higher at day 7 and day 14. Topical application of fibrin-binding domain synthetic oligopeptides from FN resulted in acceleration of full-thickness cutaneous wound healing in diabetic rats.

    Kombucha, a fermented tea (KT) is claimed to possess many beneficial properties. The aim of this study was to evaluate clinical and histopathological alterations of Kombucha tea and Nitrofurazone on cutaneous full-thickness wounds healing in rat. In present study 24 Wister -albino rats weighing 150-200 g were selected and divided to two treatment groups as Nitrofurazone ointment (0.2%) and Kombucha tea. Subsequently, the anesthesia was exerted by Ketamin hydrochloride 10% (40 mg/kg) and Xylasine (2 mg/kg) through intra muscular (IM) route. Furthermore, upon preparation of dorsal region of the animal for surgery, a piece of full-thickness skin removed (2 × 2 cm). In order to comparing wounds healing clinically and histologically, once every four days from the commencement, the wounds were photographed and the healed surface was measured by Scion image software. The clinical findings indicated that the Kombucha fungus resulted in precipitating healing than Nitrofurazone; however, it was not significant (p > 0.05). In order to pathological comparing of wound healing process, several wound biopsies were taken on 4, 8, 12, 16 and 20th days. Additionally, the histopathological results demonstrated that there was inflammation in Nitrofurazone group through twelveth day, somehow the epithelium was formed and abundant vessels were visible. Although on 16th day and the previous days the healing condition of Kombucha fungus was considered as minimal rate, revealing it is similar to Nitrofurazone group on 20th day. To wrap up. These observations suggest that the Kombucha fungus healing quality was rapid from 12th day to the end of the research, whereas no significant difference was observed.

    Acromioplasty is commonly performed during arthroscopic rotator cuff repair, but its effect on short-term outcomes is debated. To report the short-term clinical outcomes of patients undergoing arthroscopic repair of full-thickness rotator cuff tears with and without acromioplasty. Randomized controlled trial; Level of evidence, 2. Patients undergoing arthroscopic repair of full-thickness rotator cuff tears were randomized into acromioplasty or nonacromioplasty groups. The Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) score, Constant score, University of California-Los Angeles (UCLA) score, and Short Form-12 (SF-12) health assessment were collected along with physical examination including range of motion and dynamometer strength testing. Intraoperative data including tear size, repair configuration, and concomitant procedures were recorded. Follow-up examination was performed at regular intervals up to 2 years. Preoperative imaging was reviewed to classify the acromial morphologic type, acromial angle, and lateral acromial angulation. A total of 114 patients were initially enrolled in the study, and 95 (83%; 43 nonacromioplasty, 52 acromioplasty) were available for a minimum 2-year follow-up. There were no significant differences in baseline characteristics, including number of tendons torn, repair configuration, concomitant procedures, and acromion type and angles. Within groups, there was a significant (P < .001) improvement in all functional outcome scores from preoperatively to all follow-up time points, including 2 years, for the nonacromioplasty and acromioplasty groups (ASES score: 55.1-91.5, 48.8-89.0; Constant score: 48.3-75.0, 51.9-78.7, respectively). There were no significant differences in functional outcomes between nonacromioplasty and acromioplasty groups or between subjects with different acromial features at any time point. The results of this study demonstrate no difference in clinical outcomes after rotator cuff repair

    For this study we enrolled 1,615 males who were admitted to our hospital for a general health check-up. Plasma glucose (PG) and insulin were measured during 75 g OGTT, and abdominal obesity was assessed by ultrasonography in all subjects. We divided them into several groups: normal glucose tolerance (NGT), high-normal glucose tolerance (h-NGT) who showed >10.0 nmol/l at 1 hr PG among those with NGT, impaired fasting glucose (IFG), impaired glucose tolerance (IGT), IFG + IGT, and DM, according to the results of 75 g OGTT. The aim of the present study was to clarify the clinical characteristics of pre-diabetic disorders relating to metabolic syndrome by comparing various parameters including body mass index (BMI), blood levels of various lipids and abdominal wall fat index (AFI) calculated from the thickness of preperitoneal (Pmax) and subcutaneous (Smin) fat layer in the abdomen estimated by ultrasonography with insulin sensitivity determined by homeostatic model assessment (HOMA-IR) in each type of abnormal glucose regulation as classified by PG changes in 75 g OGTT. We also investigated the relationship between insulin secretion capability and insulin sensitivity to delineate the characteristics of each type of abnormal glucose regulation, and compared the area under the insulin curve (AUCins) and the time axis, and the ability of early insulin secretion by glucose loading (insulinogenic index: I.I.) in each type of abnormal glucose regulation. There was a significant positive correlation between HOMA-IR and Smin or Pmax, suggesting that Smin and Pmax may reflect insulin sensitivity. Abdominal obesity, which was diagnosed from the data of AFI, was present in the h-NGT and IFG + IGT groups, suggesting that those groups belong to the clinical entity of metabolic syndrome. HOMA-IR was higher in IFG than in IGT, although I.I. was reduced and AUCins was increased in IFG as well as in IGT. h-NGT demonstrated a slightly lower I.I. and higher AUCins, compared with IGT

    Full Text Available Endoscopic submucosal dissection (ESD is accepted as a minimally invasive treatment for colorectal cancer. However, due to technical difficulties and an increased rate of complications, ESD is not widely used in the colorectum. In some cases, endoscopic treatment alone is insufficient for disease control, and laparoscopic surgery is required. The combination of laparoscopic surgery and endoscopic resection represents a new frontier in cancer treatment. Recent developments in advanced polypectomy and minimally invasive surgical techniques will enable surgeons and endoscopists to challenge current practice in colorectal cancer treatment. Endoscopic full-thickness resection (EFTR of the colon offers the potential to decrease the postoperative morbidity and mortality associated with segmental colectomy while enhancing the diagnostic yield compared to current endoscopic techniques. However, closure is necessary after EFTR and natural transluminal endoscopic surgery (NOTES. Innovative methods and new devices for EFTR and suturing are being developed and may potentially change traditional paradigms to achieve minimally invasive surgery for colorectal cancer. The present paper aims to discuss the complementary role of ESD and the future development of EFTR. We focus on the possibility of achieving EFTR using the ESD method and closing devices.

    Articular cartilage repair remains a clinical and scientific challenge with increasing interest focused on the combined techniques of gene transfer and tissue engineering. Transforming growth factor beta 1 (TGF-{beta}{sub 1}) is a multifunctional molecule that plays a central role in promotion of cartilage repair, and inhibition of inflammatory and alloreactive immune response. Cell mediated gene therapy can allow a sustained expression of TGF-{beta}{sub 1} that may circumvent difficulties associated with growth factor delivery. The objective of this study was to investigate whether TGF-{beta}{sub 1} gene modified mesenchymal stem cells (MSCs) could enhance the repair of full-thickness articular cartilage defects in allogeneic rabbits. The pcDNA{sub 3}-TGF-{beta}{sub 1} gene transfected MSCs were seeded onto biodegradable poly-L-lysine coated polylactide (PLA) biomimetic scaffolds in vitro and allografted into full-thickness articular cartilage defects in 18 New Zealand rabbits. The pcDNA{sub 3} gene transfected MSCs/biomimetic scaffold composites and the cell-free scaffolds were taken as control groups I and II, respectively. The follow-up times were 2, 4, 12 and 24 weeks. Macroscopical, histological and ultrastructural studies were performed. In vitro SEM studies found that abundant cartilaginous matrices were generated and completely covered the interconnected pores of the scaffolds two weeks post-seeding in the experimental groups. In vivo, the quality of regenerated tissue improved over time with hyaline cartilage filling the chondral region and a mixture of trabecular and compact bone filling the subchondral region at 24 weeks post-implantation. Joint repair in the experimental groups was better than that of either control group I or II, with respect to: (1) synthesis of hyaline cartilage specific extracellular matrix at the upper portion of the defect; (2) reconstitution of the subchondral bone at the lower portion of the defect and (3) inhibition of

    Microfracture is commonly performed for cartilage repair but usually results in fibrocartilage. Microfracture augmented by autologous bone marrow concentrate (BMC) was previously shown to yield structurally superior cartilage repairs in an equine model compared with microfracture alone. The current study was performed to test the hypothesis that autologous BMC without concomitant microfracture improves cartilage repair compared with microfracture alone. Autologous sternal bone marrow aspirate (BMA) was concentrated using a commercial system. Cells from BMC were evaluated for chondrogenic potential in vitro and in vivo. Bilateral full-thickness chondral defects (15-mm diameter) were created on the midlateral trochlear ridge in 8 horses. Paired defects were randomly assigned to treatment with BMC without concomitant microfracture, or to microfracture alone. The repairs were evaluated at 1 year by in vitro assessment, arthroscopy, morphological magnetic resonance imaging (MRI), quantitative T2-weighted and ultrashort echo time enhanced T2* (UTE-T2*) MRI mapping, and histological assessment. Culture-expanded but not freshly isolated cells from BMA and BMC underwent cartilage differentiation in vitro. In vivo, cartilage repairs in both groups were fibrous to fibrocartilaginous at 1 year of follow-up, with no differences observed between BMC and microfracture by arthroscopy, T2 and UTE-T2* MRI values, and histological assessment (p > 0.05). Morphological MRI showed subchondral bone changes not observed by arthroscopy and improved overall outcomes for the BMC repairs (p = 0.03). Differences in repair tissue UTE-T2* texture features were observed between the treatment groups (p BMC was applied directly to critical-sized, full-thickness chondral defects in an equine model, the cartilage repair results were similar to those of microfracture. Our data suggest that, given the few mesenchymal stem cells in minimally manipulated BMC, other mechanisms such as paracrine, anti

    OBJECTIVE To assess effects of photobiomodulation, silver sulfadiazine, and a topical antimicrobial product for the treatment of experimentally induced full-thickness skin wounds in green iguanas (Iguana iguana). ANIMALS 16 healthy subadult green iguanas. PROCEDURES Iguanas were anesthetized, and three 5-mm cutaneous biopsy specimens were obtained from each iguana (day 0). Iguanas were randomly assigned to 2 treatment groups, each of which had a control treatment. Wounds in the topical treatment group received silver sulfadiazine, a topical antimicrobial product, or no treatment. Wounds in the laser treatment group received treatment with a class 4 laser at 5 or 10 J/cm 2 or no treatment. Wound measurements were obtained daily for 14 days. Iguanas were euthanized, and treatment sites were evaluated microscopically to detect ulceration, bacterial contamination, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity. RESULTS On day 14, wounds treated with a laser at 10 J/cm 2 were significantly smaller than those treated with silver sulfadiazine, but there were no other significant differences among treatments. Histologically, there were no significant differences in ulceration, bacterial infection, reepithelialization, necrosis, inflammation, fibrosis, and collagen maturity among treatments. CONCLUSIONS AND CLINICAL RELEVANCE Photobiomodulation at 10 J/cm 2 appeared to be a safe treatment that was tolerated well by green iguanas, but it did not result in substantial improvement in histologic evidence of wound healing, compared with results for other treatments or no treatment.

    Proper activation of macrophages (Mφ) in the inflammatory phase of acute wound healing is essential for physiological tissue repair. However, there is a strong indication that robust Mφ inflammatory responses may be causal for the fibrotic response always accompanying adult wound healing. Using a complementary approach of in vitro and in vivo studies, we here addressed the question of whether mesenchymal stem cells (MSCs)-due to their anti-inflammatory properties-would control Mφ activation and tissue fibrosis in a murine model of full-thickness skin wounds. We have shown that the tumor necrosis factor-α (TNF-α)-stimulated protein 6 (TSG-6) released from MSCs in co-culture with activated Mφ or following injection into wound margins suppressed the release of TNF-α from activated Mφ and concomitantly induced a switch from a high to an anti-fibrotic low transforming growth factor-β1 (TGF-β1)/TGF-β3 ratio. This study provides insight into what we believe to be a previously undescribed multifaceted role of MSC-released TSG-6 in wound healing. MSC-released TSG-6 was identified to improve wound healing by limiting Mφ activation, inflammation, and fibrosis. TSG-6 and MSC-based therapies may thus qualify as promising strategies to enhance tissue repair and to prevent excessive tissue fibrosis.

    A novel technique to reduce donor site morbidity after radial forearm free flap (RFFF) harvest, using a local full-thickness skin graft (FTSG), is described. Thirty consecutive patients undergoing RFFF for head and neck reconstruction were enrolled in a prospective study. Donor site defect closure was performed with spindle-shaped FTSGs excised from the wavelike skin incision made for the vascular pedicle. Both the removal site of the FTSG on the volar forearm and the covered RFFF donor site healed uneventfully in 29 cases, with no impairment of function related to the skin graft. No skin graft failure and no exposure, tenting, or adherence of the flexor tendons occurred. All patients expressed satisfaction with postoperative pain, the functional outcome, and cosmetic appearance. Primary donor site defect closure could be achieved in all cases with the use of a local FTSG. This graft can be gained at the access incision for the vascular pedicle, avoids expansion of the incision for a local flap technique, and does not prolong wound healing, and thus reduces both donor site and graft site morbidity of the RFFF. This technique leads to an inconspicuous aesthetic result with no apparent relevant functional deficits and avoids the need for a second donor site.

    To assess the prevalence of sonographic visualization of the rotator cable in patients with symptomatic full-thickness rotator cuff tears and asymptomatic controls and to correlate rotator cable visualization with tear size, muscular fatty infiltration and atrophy, and the functional outcome in the patients with rotator cuff tears. Fifty-seven patients with rotator cuff tears and 30 asymptomatic volunteers underwent shoulder sonography for prospective assessment of the rotator cable and rotator cuff tear and responded to 2 functional outcome questionnaires (shortened Disabilities of the Arm, Shoulder, and Hand [QuickDASH] and Constant). In the patients with rotator cuff tears, appropriate tests were used to correlate rotator cable visualization with the tear size, functional outcome, muscular fatty infiltration, and atrophy. The patients with rotator cuff tears included 25 women and 32 men (mean age,57 years; range, 39-67 years), and the volunteers included 13 women and 17 men (mean age, 56 years; range, 35-64 years). The rotator cable was identified in 77% (23 of 30) of controls and 23% (13 of 57) of patients with rotator cuff tears. In the patients, nonvisualization of the rotator cable correlated with larger tears (P tears than asymptomatic controls and was associated with a larger tear size and greater supraspinatus fatty infiltration and atrophy. Diligent assessment of the supraspinatus muscle should be done in patients with rotator cuff tears without a visible rotator cable, as the integrity of these anatomic structures may be interdependent.

    This article presents successful incorporation of ibuprofen in polylactic acid (PLA) nanofibers to create scaffolds for the treatment of both acute and chronic wounds. Nanofibrous PLA scaffolds containing 10, 20, or 30 wt % ibuprofen were created and ibuprofen release profiles quantified. In vitro cytotoxicity to human epidermal keratinocytes (HEK) and human dermal fibroblasts (HDF) of the three scaffolds with varying ibuprofen concentrations were evaluated and compared to pure PLA nanofibrous scaffolds. Thereafter, scaffolds loaded with ibuprofen at the concentration that promoted human skin cell viability and proliferation (20 wt %) were evaluated in vivo in nude mice using a full thickness skin incision model to determine the ability of these scaffolds to promote skin regeneration and/or assist with scarless healing. Both acellular and HEK and HDF cell-seeded 20 wt % ibuprofen loaded nanofibrous bandages reduced wound contraction compared with wounds treated with Tegaderm™ and sterile gauze. Newly regenerated skin on wounds treated with cell-seeded 20 wt % ibuprofen bandages exhibited significantly greater blood vessel formation relative to acellular ibuprofen bandages. We have found that degradable anti-inflammatory scaffolds containing 20 wt % ibuprofen promote human skin cell viability and proliferation in vitro, reduce wound contraction in vivo, and when seeded with skin cells, also enhance new blood vessel formation. The approaches and results reported here hold promise for multiple skin tissue engineering and wound healing applications. © 2015 Wiley Periodicals, Inc.

    Objective: To investigate the effects of human amniotic epithelial stem cells-derived exosomes on healing of wound with full-thickness skin defect in rats. Methods: (1) Human amniotic epithelial stem cells were isolated from the amnion tissue of 5 full-term pregnant women in Department of Obstetrics of our hospital by the method of trypsin digestion, and their morphology was observed. The third passage of cells were stained with rhodamine-phalloidin for cytoskeleton observation. The third passage of cells were identified with flow cytometry through the detection of expressions of cell surface markers CD29, CD31, CD34, CD90, CD105, SSEA3, SSEA4 and immunity-related marker human leukocyte antigen-D related site (HLA-DR). The third passage of cells were also assessed the ability of adipogenic and osteogenic differentiation. (2) The third passage of human amniotic epithelial stem cells were cultured in DMEM medium supplemented with 10% exosome-free fetal bovine serum. Exosomes were isolated from culture supernatant by the method of ultracentrifugation and represented with scanning electron microscope for morphologic observation. (3) Six adult SD rats were anesthetized, and four 1 cm×1 cm sized wounds with full-thickness skin defect were made on the back of each rat. The wounds on the back of each rat were divided into control group, 25 μg/mL exosomes group, 50 μg/mL exosomes group, and 100 μg/mL exosomes group according to the random number table (with 6 wounds in each group), and a total volume of 100 μL phosphate buffered saline, 25 μg/mL exosomes, 50 μg/mL exosomes, and 100 μg/mL exosomes were evenly injected around the wound through multiple subcutaneous sites, respectively. The wound healing rate was calculated based on measurement on post injury day (PID) 7, 14, and 21. On PID 21, the healed wound tissue of each group was collected and stained with HE to observe and count skin accessories, and the arrangement of collagen fibers was observed with Masson

    Abdominal injury is an important cause of morbidity and mortality in childhood. Ten percent of trauma-related deaths are due to abdominal injury. Thousands of children are involved in auto accidents annually; many suffer severe internal injury. Child abuse is a second less frequent but equally serious cause of internal abdominal injury. The descriptions of McCort and Eisenstein and their associates in the 1960s first brought to attention the frequency and severity of visceral injury as important manifestations of the child abuse syndrome. Blunt abdominal trauma often causes multiple injuries; in the past, many children have been subjected to exploratory surgery to evaluate the extent of possible hidden injury. Since the advent of noninvasive radiologic imaging techniques including radionuclide scans and ultrasound and, especially, computed tomography (CT), the radiologist has been better able to assess (accurately) the extent of abdominal injury and thus allow conservative therapy in many cases. Penetrating abdominal trauma occurs following gunshot wounds, stabbing, and other similar injury. This is fortunately, a relatively uncommon occurrence in most pediatric centers and will not be discussed specifically here, although many principles of blunt trauma diagnosis are valid for evaluation of penetrating abdominal trauma. If there is any question that a wound has extended intraperitonelly, a sinogram with water-soluble contrast material allows quick, accurate diagnosis. The presence of large amounts of free intraperitoneal gas suggests penetrating injury to the colon or other gas-containing viscus and is generally considered an indication for surgery

    In this study, poly(L-lactide) (PLLA)/halloysite nanotube (HNT) electrospun mats were prepared as a dual-drug delivery system. HNTs were used to encapsulate polymyxin B sulphate (a hydrophilic drug). Dexamethasone (a hydrophobic drug) was directly dissolved in the PLLA solution. The drug-loaded HNTs with optimised encapsulation efficiency were then mixed with the PLLA solution for subsequent electrospinning to form composite dual-drug-loaded fibre mats. The structure, morphology, degradability and mechanical properties of the electrospun composite mats were characterised in detail. The results showed that the HNTs were uniformly distributed in the composite PLLA mats. The HNTs content in the mats could change the morphology and average diameter of the electrospun fibres. The HNTs improved both the tensile strength of the PLLA electrospun mats and their degradation ratio. The drug-release kinetics of the electrospun mats were investigated using ultraviolet-visible spectrophotometry. The HNTs/PLLA ratio could be varied to adjust the release of polymyxin B sulphate and dexamethasone. The antibacterial activity in vitro of the mats was evaluated using agar diffusion and turbidimetry tests, which indicated the antibacterial efficacy of the dual-drug delivery system against Gram-positive and -negative bacteria. Healing in vivo of infected full-thickness burns and infected wounds was investigated by macroscopic observation, histological observation and immunohistochemical staining. The results indicated that the electrospun mats were capable of co-loading and co-delivering hydrophilic and hydrophobic drugs, and could potentially be used as novel antibacterial wound dressings. © The Author(s) 2015.

    Objective: To study the antiseptic effect of compound lysostaphin disinfectant and its preventive effect on infection of artificial dermis after graft on full-thickness skin defect wound in rats. Methods: (1) Each one standard strain of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were selected. Each 20 clinical strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were collected from those isolated from wound exudates of burn patients hospitalized in our wards from January 2014 to December 2016 according to the random number table. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of compound lysostaphin disinfectant to above-mentioned strains were detected. The experiment was repeated 3 times. Compared with the corresponding standard strain, the clinical strain with higher MIC and/or MBC was considered as having decreased sensitivity to the disinfectant. The percentage of strains of each of the three kinds of bacteria with decreased sensitivity was calculated. (2) Artificial dermis pieces were soaked in compound lysostaphin disinfectant for 5 min, 1 h, 2 h, and 4 h, respectively, with 21 pieces at each time point. After standing for 0 (immediately), 12, 24, 36, 48, 60, 72 h (with 3 pieces at each time point), respectively, the diameters of their inhibition zones to standard strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were measured. The experiment was repeated 3 times. The shortest soaking time corresponding to the longest standing time, after which the disinfectant-soaked artificial dermis could form an effective inhibition zone (with diameter more than 7 mm), was the sufficient soaking time of the disinfectant to the artificial dermis. (3) Forty Sprague-Dawley rats were divided into post injury day (PID) 3, 7, 14, and 21 sampling groups according to the random number table, with 10 rats in each group. A full-thickness skin

    Changes in morphology of the skin are an important factor that can affect non-invasive measurements performed through this organ, in particular for glucose monitoring in e.g. patients with diabetes mellitus. A characterization technique for non-contact in vivo profiling of the superficial skin layers can be beneficial for evaluation of the performance of such measurement systems. We applied a full-field optical coherence tomography (OCT) system followed by the fully automatic processing for this task. With the developed procedure, non-invasive quantification of the skin morphology can be performed within a few minutes. The dorsal skin of the upper arm of 22 patients with Type 1 Diabetes Mellitus was investigated with an OCT system and with a commercially available dermatological laser scanning confocal microscope (CM) as a reference method. The estimates of epidermal thickness from OCT were compared with the results of expert-assisted analysis of confocal images. The highest correlation with the CM measurements has been obtained for the distance from the entrance peak to the first minimum of the OCT reflection profile (R-bar 2 = 0.657, p < 0.0001). In this specific patient group, we have observed a statistically significant correlation of the subjects' body mass index with the distance from the entrance peak to the dermal reflection peak in the OCT profile (p = 0.010). Furthermore, the same OCT parameter is negatively correlated with age with marginal statistical significance (p = 0.062). At the same time, no relation of diabetes-related parameters (duration of disease and concentration of glycated haemoglobin) to the skin morphology observed with the OCT and CM was found

    The anterior rotator cable is critical in force transmission of the rotator cuff. However, few clinical studies have examined the correlation between the integrity of the anterior supraspinatus tendon and surgical outcomes in patients with rotator cuff tears. To compare the clinical and structural outcomes of the arthroscopic repair of full-thickness rotator cuff tears with and without anterior disruption of the supraspinatus tendon. Cohort study; Level of evidence, 3. One hundred eighty-one shoulders available for magnetic resonance imaging (MRI) at least 6 months after arthroscopic rotator cuff repair, with a minimum 1-year follow-up, were enrolled. The anterior attachment of the rotator cable was disrupted in 113 shoulders (group A) and intact in 68 shoulders (group B). The mean age at the time of surgery in groups A and B was 59.6 and 59.2 years, respectively, and the mean follow-up period was 24.2 and 25.1 months, respectively. There were statistically significant differences in the preoperative tear size and pattern and muscle fatty degeneration between the 2 groups ( P = .004, P = .008, and P rotator cable, the mean 24-month follow-up demonstrated excellent pain relief and improvement in the ability to perform activities of daily living after arthroscopic rotator cuff repair. However, tears with anterior disruption of the rotator cable showed a significantly larger and more complex tear pattern and more advanced fatty degeneration. Additionally, the retear rate was significantly higher in patients with a tear involving the anterior attachment of the rotator cable.

    To determine whether internal limiting membrane (ILM) peeling is cost-effective compared with no peeling for patients with an idiopathic stage 2 or 3 full-thickness macular hole. A cost-effectiveness analysis was performed alongside a randomised controlled trial. 141 participants were randomly allocated to receive macular-hole surgery, with either ILM peeling or no peeling. Health-service resource use, costs and quality of life were calculated for each participant. The incremental cost per quality-adjusted life year (QALY) gained was calculated at 6 months. At 6 months, the total costs were on average higher (£424, 95% CI -182 to 1045) in the No Peel arm, primarily owing to the higher reoperation rate in the No Peel arm. The mean additional QALYs from ILM peel at 6 months were 0.002 (95% CI 0.01 to 0.013), adjusting for baseline EQ-5D and other minimisation factors. A mean incremental cost per QALY was not computed, as Peeling was on average less costly and slightly more effective. A stochastic analysis suggested that there was more than a 90% probability that Peeling would be cost-effective at a willingness-to-pay threshold of £20,000 per QALY. Although there is no evidence of a statistically significant difference in either costs or QALYs between macular hole surgery with or without ILM peeling, the balance of probabilities is that ILM Peeling is likely to be a cost-effective option for the treatment of macular holes. Further long-term follow-up data are needed to confirm these findings.

    Full Text Available Abdominal elephantiasis is a rare entity. Abdominal elephantiasis is an uncommon, but deformative and progressive cutaneous disease caused by chronic lymphedema and recurrent streptococcal or Staphylococcus infections of the abdominal wall. We present 3 cases of patients with morbid obesity who presented to our hospital with abdominal wall swelling, thickening, erythema, and pain. The abdominal wall and legs were edematous, with cobblestone-like, thickened, hyperpigmented, and fissured plaques on the abdomen. Two patients had localised areas of skin erythema, tenderness, and increased warmth. There was purulent drainage from the abdominal wall in one patient. They were managed with antibiotics with some initial improvement. Meticulous skin care and local keratolytic treatment for the lesions were initiated with limited success due to their late presentation. All three patients refused surgical therapy. Conclusion. Early diagnosis is important for the treatment of abdominal elephantiasis and prevention of complications.

    Full Text Available Background: Graft survival has been considered the major problem in reconstructive surgery. Clinical studies have helped us to understand the role of PRP in increasing skin survival. Our goal in this study was to examine the treatment effects of platelet-rich plasma (PRP and platelet-rich fibrin (PRF on autologous full thickness skin graft survival in male rats. Methods: This experimental study was performed on 36 rats of Sprague-Dawley race with weighing approximately 250 to 300 gr on May 2015 in animal laboratory of Hazrat Fatima Hospital. After anesthesia, rats were divided into 3 groups. We injected platelet-rich plasma (PRP in the first group, platelet-rich fibrin (PRF in the second and saline in the third group after removing the skin. Microscopic analysis was performed with camera (Canon powershot SX200, Tokyo, Japan on days 7, 14, 21 and 28 after surgery. We used image analysis system (ImageJ, ver. 1.45 to examine necrosis and survival rate. Samples were studied with H&E staining on day 28 microscopically for histological analysis of vascular density and angiogenesis. Results: Our findings showed the area of necrosis in animals injected with PRP on days 7 and 14, was meaningfully less than control group (P= 0.0001. There was no meaningful difference between control and PRP groups (P> 0.05. The area of necrosis in animals injected with PRF did not have any significant difference with control group from beginning to 21st day (P< 0.0001. there was no meaningful difference in vascular density between control and PRP group, whereas in animals injected with PRF the vascular density was significantly less than control group (P= 0.002. Conclusion: According to our results in this study, we can conclude that using autologous PRP can enhance the process of healing soft tissue injury and be affective at increasing graft survival. This method is suggested to be conducted for patients highly at risk of graft loss and also for those who are in need of

    Full Text Available BACKGROUND: Platelet-rich products (PRP are widely used for rotator cuff tears. However, whether platelet-rich products produce superior clinical or radiological outcomes is controversial. This study aims to use meta-analysis to compare clinical and radiological outcomes between groups with or without platelet-rich products. METHODS: The Pubmed, Embase, and Cochrane library databases were searched for relevant studies published before April 20, 2013. Studies were selected that clearly reported a comparison between the use or not of platelet-rich products. The Constant, ASES, UCLA, and SST scale systems and the rotator cuff retear rate were evaluated. The weighted mean differences and relative risks were calculated using a fixed-effects model. RESULTS: Seven studies were enrolled in this meta-analysis. No significant differences were found for the Constant scale (0.73, 95% CI, -1.82 to 3.27, P=0.58, ASES scale (-2.89, 95% CI, -6.31 to 0.53, P=0.1, UCLA scale (-0.79, 95% CI, -2.20 to 0.63, P=0.28, SST scale (0.34, 95% CI, -0.01 to 0.69, P=0.05, and the overall rotator cuff retear rate (0.71, 95% CI, 0.48 to 1.05, P=0.08. Subgroup analysis according to the initial tear size showed a lower retear rate in small- and medium-sized tears (0.33, 95% CI, 0.12 to 0.91, P=0.03 after platelet-rich product application but no difference for large- and massive-sized tears (0.86, 95% CI, 0.60 to 1.23, P=0.42. CONCLUSION: In conclusion, the meta-analysis suggests that the platelet-rich products have no benefits on the overall clinical outcomes and retear rate for the arthroscopic repair of full-thickness rotator cuff tears. However, a decrease occurred in the rate of retears among patients treated with PRP for small- and medium-sized rotator cuff tears but not for large- and massive-sized tears. LEVEL OF EVIDENCE: Level II.

    Abdominal epilepsy (AE) is a rather uncommon clinical entity in children that might create diagnostic confusion especially when it lacks the typical manifestations of an epileptic seizure. We report the case of a young boy having apparently unexplained episodes of paroxysmal abdominal symptoms with no other suggestion of an underlying epileptic disorder. The case also explains how the clinical presentation can be misleading unless a high index of suspicion is maintained to reach the ultimate diagnosis. (author)

    The presence of an articular cartilage lesion in anterior cruciate ligament-injured knees is considered a predictor of osteoarthritis. This study was undertaken to evaluate risk factors for full-thickness articular cartilage lesions in anterior cruciate ligament-injured knees, in particular the role of gender and the sport causing the initial injury. Cohort study (prognosis); Level of evidence, 2. Primary unilateral anterior cruciate ligament reconstructions prospectively registered in the Swedish and the Norwegian National Knee Ligament Registry during 2005 through 2008 were included (N = 15 783). Logistic regression analyses were used to evaluate risk factors for cartilage lesions. A total of 1012 patients (6.4%) had full-thickness cartilage lesions. The median time from injury to surgery was 9 months (range, 0 days-521 months). Male patients had an increased odds of full-thickness cartilage lesions compared with females (odds ratio = 1.22; 95% confidence interval, 1.04-1.42). In males, team handball had an increase in the odds of full-thickness cartilage lesions compared with soccer (odds ratio = 2.36; 95% confidence interval, 1.33-4.19). Among female patients, no sport investigated showed a significant decrease or increase in the odds of full-thickness cartilage lesions. The odds of a full-thickness cartilage lesion increased by 1.006 (95% confidence interval, 1.005-1.008) for each month elapsed from time of injury until anterior cruciate ligament reconstruction when all patients were considered, while time from injury to surgery did not affect the odds significantly in those patients reconstructed within 1 year of injury (odds ratio = 0.98; 95% confidence interval, 0.95-1.02). Previous surgery increased the odds of having a full-thickness cartilage lesion (odds ratio = 1.40; 95% confidence interval, 1.21-1.63). One year of increasing patient age also increased the odds (odds ratio = 1.05; 95% confidence interval, 1.05-1.06). Male gender is associated with an

    Objective: To compare the effects of sterilized air and perfluoropropane (C(3)F(8)) tamponades on recovery after vitrectomy for the treatment of idiopathic full-thickness macular hole (IFTMH). Methods: Case control study. Seventy-three eyes of 69 consecutive cases underwent vitrectomy with air (53 eyes) or 10% C(3)F(8) gas (20 eyes) tamponade. Surgical outcomes were retrospectively analyzed between the two groups, including logarithm of the minimal angle of resolution (logMAR) and optical coherence tomography findings like the size of the macular hole and the photoreceptor layer defect. Results: Preoperatively, the mean best corrected visual acuity (BCVA) was (0.10±0.49), the mean hole diameter was (777.9±320.7) μm, and the mean diameter of the photoreceptor layer defect was (1 709.3±516.0) μm in the sterilized air group, while in the C(3)F(8) group, the mean BCVA was (0.07±0.50), the mean hole diameter was (853.9±355.0) μm, and the mean defect diameter was (1 480.5±429.9) μm. The primary closure rate was 90.6% in the sterilized air group and 95.0% in the C(3)F(8) group. One month after surgery, the mean BCVA was (0.17±0.41), and the mean diameter of the photoreceptor layer defect was (820.5±598.0) μm in the sterilized air group, while in the C(3)F(8) group, the mean BCVA was 0.12±0.49, and the mean defect diameter was (762.5±658.0) μm. There was no statistically significant difference in the closure rate (χ(2)=0.019), BCVA ( t =-1.689), hole diameter ( t =0.837) and diameter of the photoreceptor layer defect ( t =0.338) between the two groups( P >0.05). Conclusions: Vitrectomy with sterilized air tamponade is safe and effective for the treatment of IFTMH and even cases with relatively large diameters. (Chin J Ophthalmol, 2017, 53: 327 - 331) .

    Research suggests high-voltage, pulsed-current electric therapy (HVPC) is safe and effective for treating chronic wounds, and some data suggest silver- and collagen-based dressings may facilitate healing. A combination therapy utilizing both HVPC and silver-collagen dressing may present clinical advantages. To explore the effect of the combined therapy for chronic full-thickness wounds, a prospective, consecutive case series study was conducted. All participants were adults with wounds of at least 6 weeks' duration. After obtaining informed consent, patient and wound characteristics were obtained, wounds were assessed and measured, and patients received 2 to 3 HVPC treatments per week followed by application of the silver- and collagen-based dressing for a period of 2 weeks. Data were analyzed descriptively, and changes in wound size and volume from baseline were analyzed using Wilcoxon Signed Rank Test. The dressings were saturated with normal saline, used simultaneously during the 45-minute HVPC treatment, and left on top of the wound after treatment. The HVPC electro pads (stainless steel electrodes with a sponge interface) also were moistened with normal saline and the cathode placed on top of the wound. If the patient had more than 1 wound on the same leg, the anode was placed on the additional wound (otherwise over the intact skin nearby). Secondary dressings (eg, foam and/ or gauze) were used as clinically appropriate, and a 4-layer compression wrap was used, if indicated, for patients with venous ulcers. Ten (10) patients (3 women, 7 men, 57.30 ± 9.70 years old with 14 wounds of 273.10 ± 292.03 days' duration before study) completed the study and were included in the final analyses. Average wound surface area decreased from 13.78 ± 21.35 cm(2) to 9.07 ± 16.81 cm(2) (42.52% ± 34.16% decrease, P = 0.002) and wound volume decreased from 3.39 ± 4.31 cm(3) to 1.28 ± 2.25 cm(3) (66.84% ± 25.07% decrease, P = 0.001).

    The inverted flap (IF) technique has recently been introduced in macular hole (MH) surgery. The IF technique has shown an increase of the success rate in the case of large MHs and in MHs associated with high myopia. This study reports the anatomical and functional results in a large series of patients affected by MH treated using pars plana vitrectomy and gas tamponade combined with internal limiting membrane (ILM) peeling or IF. This is a retrospective, consecutive, nonrandomized comparative study of patients affected by idiopathic or myopic MH treated using small-gauge pars plana vitrectomy (25- or 23-gauge) between January 2011 and May 2016. The patients were divided into two groups according to the ILM removal technique (complete removal vs. IF). A subgroup analysis was performed according to the MH diameter (MH peeling and 320 patients underwent pars plana vitrectomy and IF. Overall, 84.94% of the patients had complete anatomical success characterized by MH closure after the operation. In particular, among the patients who underwent only ILM peeling the closure rate was 78.75%; among the patients who underwent the IF technique, it was 91.93% (P = 0.001); and among the patients affected by full-thickness MH ≥400 µm, success was achieved in 95.6% of the cases in the IF group and in 78.6% in the ILM peeling group (P = 0.001); among the patients with an axial length ≥26 mm, success was achieved in 88.4% of the cases in the IF group and in 38.9% in the ILM peeling group (P = 0.001). Average preoperative best-corrected visual acuity was 0.77 (SD = 0.32) logarithm of the minimum angle of resolution (20/118 Snellen) in the peeling group and 0.74 (SD = 0.33) logarithm of the minimum angle of resolution (20/110 Snellen) in the IF group (P = 0.31). Mean postoperative best-corrected visual acuity was 0.52 (SD = 0.42) logarithm of the minimum angle of resolution (20/66 Snellen) in the peeling group and 0.43 (SD = 0.31) logarithm of the minimum angle of resolution (20

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    Tissue engineering has progressed in delivering laboratory-expanded keratinocytes to the clinic; however the production of a suitable alternative to a skin graft, containing both epidermis and dermis still remains a challenge. To develop a one-step approach to wound reconstruction using finely minced split thickness skin and a biodegradable synthetic dermal substitute. This was explored in vitro using scalpel diced pieces of split thickness human skin combined with synthetic electrospun polylactide (PLA) scaffolds. To aid the spreading of tissue, 1% methylcellulose was used and platelet releasate was examined for its effect on cellular outgrowth from tissue explants. The outcome parameters included the metabolic activity of the migrating cells and their ability to produce collagen. Cell presence and migration on the scaffolds were assessed using fluorescence microscopy and SEM. Cells were identified as keratinocytes by immunostaining for pan-cytokeratin. Collagen deposition was quantified by using Sirius red. Skin cells migrated along the fibers of the scaffold and formed new collagen. 1% methylcellulose improved the tissue handling properties of the minced skin. Platelet releasate did not stimulate the migration of skin cells along scaffold fibers. Immunohistochemistry and SEM confirmed the presence of both epithelial and stromal cells in the new tissue. We describe the first key steps in the production of a skin substitute to be assembled in theatre eliminating the need for cell culture. Whilst further experiments are needed to develop this technique it can be a useful addition to armamentarium of the reconstructive surgeon. Copyright © 2013 Elsevier Ltd and ISBI.

    To compare the hydro-surgical technique to traditional techniques for removal of subcutaneous tissue in the preparation of full-thickness skin grafts. Ex vivo experimental study and a single clinical case report. Four canine cadavers and a single clinical case. Four sections of skin were harvested from the lateral flank of recently euthanatized dogs. Traditional preparation methods used included both a blade or scissors technique, each of which were compared to the hydro-surgical technique individually. Preparation methods were compared based on length of time for removal of the subcutaneous tissue from the graft, histologic grading, and measurable thickness as compared to an untreated sample. The hydro-surgical technique had the shortest skin graft preparation time as compared to traditional techniques (p = 0.002). There was no significant difference in the histological grading or measurable subcutaneous thickness between skin specimens. The hydro-surgical technique provides a rapid, effective debridement of subcutaneous tissue in the preparation of full-thickness skin grafts. There were not any significant changes in histological grade and subcutaneous tissue remaining among all treatment types. Additionally the hydro-surgical technique was successfully used to prepare a full-thickness meshed free skin graft in the reconstruction of a traumatic medial tarsal wound in a dog.

    Full text: Immunoglobulin G4-related disease was recognized as a systemic disease since various extrapancreatic lesions were observed in patients with autoimmune pancreatitis (AIP). The real etiology and pathogenesis of IgG4-RD is still not clearly understood. Moreover the exact role of IgG4 or IgG4-positive plasma cells in this disease has not yet been elucidated. only some inconsistent biological features such as hypergammaglobulinemia or hypocomplementemia support the autoimmune nature of the disease process. various names have been ascribed to this clinicopathological entity including IgG4-related sclerosing disease, IgG4-related systemic sclerosing disease, IgG4-related disease, IgG4-related autoimmune disease, hyper-IgG4 disease and IgG4-related systemic disease. The extrapancreatic lesions of IgG4-RD also exhibit the same characteristic histologic features including dense lymphoplasmacytic infiltrate, massive storiform fibrosis, and obliterative phlebitis as seen in IgG4-related pancreatitis. Abdominal manifestations include the following organs/systems: Bile ducts: Sclerosing cholangitis; Gallbladder and liver: Acalculous sclerosis cholecytitis with diffuse wall thickening; hepatic inflammatory pseudotumorts; Kidneys: round or wedge-shaped renal cortical nodules, peripheral cortical; lesions, mass like lesions or renal pelvic involvement; Prostate, urethra, seminal vesicle, vas deferens, uterine cervix; Autoimmune prostatitis; Retroperitoneum: Retroperitoneal fibrosis. thin or mildly thick homogeneous soft tissue lesion surrounding the abdominal aorta and its branches but also bulky masses causing hydronephroureterosis; Mesentery: Sclerosing mesenteritis usually involving the root of the mesentery; Bowel: Inflammatory bowel diseases mimicking Crohn’s disease or ulcerative colitis. various types of sclerosing nodular lesions of the bowel wall; Stomach: Gastritis, gastric ulcers and focal masses mimicking submucosal tumor; omentum: Infiltration mimicking

    Abdominal angina due to occlusive disease of the mesenteric arteries has been the to become clinically manifest only in the presence of severe disease in at least two of the following vessels: celiac, SMA, and IMA. Still, many patients who gradually develop significant two-vessel disease have few or no associated symptoms. Differences in collateral circulation and in cardiac index account for some of the clinical variation. The usual clinical manifestations include severe post-prandial pain, sitophobia (fear of eating because of the anticipated symptoms), and profound weight loss. Uncommonly, diarrhea, nausea, or vomiting may be encountered. Smoking is a common historical feature. Most series document a female predilection. Aside from occasional abdominal bruits and (more commonly) findings of peripheral vascular occlusive disease, the physical exam discloses only cachexia. But the differential diagnosis of profound weight loss is extensive. Therefore, abdominal angina has always created a diagnostic challenge. Multiple imaging modalities are often employed, and a seemingly negative evaluation often culminates in biplane aortography. The latter typically reveals stenoses and/or occlusions in at least two of the three mesenteric arteries. The authors discuss how a variety of surgical treatments, including thromboendarterectomy and bypass grafting, have evolved. Recently reported results have been excellent

    To describe the safety and efficacy of a technique to close large thickness macular holes. A consecutive retrospective interventional case series of 16 patients with macular holes greater than 650 microns in "aperture" diameter were included. The technique involves vitrectomy, followed by internal limiting membrane peeling. The macula is detached using subretinal injection of saline. Fluid-air exchange is performed to promote detachment and stretch of the retina. After this, the standard fluid-air exchange is performed and perfluoropropane gas is injected. Face-down posturing is advised. Adverse effects, preoperative, and postoperative visual acuities were recorded. Optical coherence tomography scans were also taken. The mean hole size was 739 microns (SD: 62 microns; mean base diameter: 1,311 microns). Eighty-three percent (14 of 16) of eyes had successful hole closure after the procedure. At 12-month follow-up, no worsening in visual acuity was reported, and improvement in visual acuity was noted in 14 of 16 eyes. No patients lost vision because of the procedure. It is possible to achieve anatomical closure of large macular holes using RETMA. No patients experienced visual loss. The level of visual improvement is likely limited because of the size and chronicity of these holes.

    The purpose of this study was to compare the structural outcomes of a single-row rotator cuff repair and double-row suture bridge fixation after arthroscopic repair of a full-thickness supraspinatus rotator cuff tear. We evaluated with diagnostic ultrasound a consecutive series of ninety shoulders in ninety patients with full-thickness supraspinatus tears at an average of 10 months (range, 6-12) after operation. A single surgeon at a single hospital performed the repairs. Inclusion criteria were full-thickness supraspinatus tears less than 25 mm in their anterior to posterior dimension. Exclusion criteria were prior operations on the shoulder, partial thickness tears, subscapularis tears, infraspinatus tears, combined supraspinatus and infraspinatus repairs and irreparable supraspinatus tears. Forty-three shoulders were repaired with single-row technique and 47 shoulders with double-row suture bridge technique. Postoperative rehabilitation was identical for both groups. Ultrasound criteria for healed repair included visualization of a tendon with normal thickness and length, and a negative compression test. Eighty-three patients were available for ultrasound examination (40 single-row and 43 suture-bridge). Thirty of 40 patients (75%) with single-row repair demonstrated a healed rotator cuff repair compared to 40/43 (93%) patients with suture-bridge repair (P = .024). Arthroscopic double-row suture bridge repair (transosseous equivalent) of an isolated supraspinatus rotator cuff tear resulted in a significantly higher tendon healing rate (as determined by ultrasound examination) when compared to arthroscopic single-row repair.

    Partial-thickness rotator cuff tears (PTRCTs) are one of the leading causes of shoulder dysfunction. Successful results have been reported with different treatment techniques, but the long-term consequences of these procedures are not yet clearly known. The purposes of this study were to evaluate and compare the mid- and long-term clinical outcomes of arthroscopically repaired bursal-side PTRCTs after conversion to full-thickness tears and identify the possible effects of age, gender, and hand dominance on clinical outcomes. Twenty-nine patients who had undergone arthroscopic repair of a significant bursal-side PTRCT were functionally evaluated. The repair was made after conversion to a full-thickness tear. The average patient age was 55.2 years (range 35-69 years, SD ±7.6 years). Clinical outcomes were evaluated at 2 and 5 years after surgery. Constant Shoulder Score (CSS) and Visual Analogue Scale for Pain (VAS pain) were used as outcome measures. The average CSS improved from 38.9 preoperatively to 89.2 and 87.8 at 2 and 5 years after surgery, respectively (p functional outcomes and VAS pain scores at 2 and 5 years after surgery compared with the preoperative period. The patients who underwent surgery from their non-dominant extremity showed a significantly higher CSS increase relative to those who underwent surgery on the dominant extremity (p = 0.022). Arthroscopic repair of high-grade bursal-side PTRCTs after conversion to full-thickness tears is a reliable surgical technique with good functional outcomes and pain relief both at mid- and long-term follow-ups. Surgery on the non-dominant side may be related to better functional outcomes.

    Full Text Available Irritable bowel syndrome (IBS is a functional gastrointestinal (GI disorder of unknown etiology. Although relatively common in children, how this condition affects brain structure and function in a pediatric population remains unclear. Here, we investigate brain changes in adolescents with IBS and healthy controls. Imaging was performed with a Siemens 3 Tesla Trio Tim MRI scanner equipped with a 32-channel head coil. A high-resolution T1-weighted anatomical scan was acquired followed by a T2-weighted functional scan. We used a surface-based morphometric approach along with a seed-based resting-state functional connectivity (RS-FC analysis to determine if groups differed in cortical thickness and whether areas showing structural differences also showed abnormal RS-FC patterns. Patients completed the Abdominal Pain Index and the GI Module of the Pediatric Quality of Life Inventory to assess abdominal pain severity and impact of GI symptoms on health-related quality of life (HRQOL. Disease duration and pain intensity were also assessed. Pediatric IBS patients, relative to controls, showed cortical thickening in the posterior cingulate (PCC, whereas cortical thinning in posterior parietal and prefrontal areas were found, including the dorsolateral prefrontal cortex (DLPFC. In patients, abdominal pain severity was related to cortical thickening in the intra-abdominal area of the primary somatosensory cortex (SI, whereas HRQOL was associated with insular cortical thinning. Disease severity measures correlated with cortical thickness in bilateral DLPFC and orbitofrontal cortex. Patients also showed reduced anti-correlations between PCC and DLPFC compared to controls, a finding that may reflect aberrant connectivity between default mode and cognitive control networks. We are the first to demonstrate concomitant structural and functional brain changes associated with abdominal pain severity, HRQOL related to GI-specific symptoms, and disease

    Objective: To evaluate abdominal imaging in AIDS. Methods: The imaging examinations (including US, CT and MR) of 6 patients with AIDS associated abdominal foci were analysed retrospectively. All the cases were performed US, and CT scan, of which 4 performed enhanced CT scan and 1 with MR. Results: Abdominal tuberculosis were found in 4 patients, including abdominal lymph nodes tuberculosis (3 cases) and pancreatic tuberculosis (1 case). The imaging of lymph nodes tuberculosis typically showed enlarged peripheral tim enhancement with central low-attenuation on contrast-enhanced CT. Pancreatic tuberculosis demonstrated low-attenuation area in pancreatic head and slightly peripheral enhancement. Disseminated Kaposi's sarcoma was seen in 1 case: CT and MRI scan demonstrated tumour infiltrated along hepatic portal vein and bronchovascular bundles. Pelvic tumor was observed in 1 case: CT scan showed large mass with thick and irregular wall and central low attenuation liquefacient necrotic area in the pelvic cavity. Conclusion: The imaging findings of AIDS with abdominal foci is extraordinarily helpful to the diagnosis of such disease. Tissue biopsy is needed to confirm the diagnosis. (authors)

    Full Text Available Background: The purpose of this study was to create biomaterial scaffolds like platelet-rich plasma (PRP and platelet-rich fibrin (PRF containing stromal cell-derived factor-1 (SDF1 as a chemokine to induce hyaline cartilage regeneration of rabbit knee in a full thickness defect. Methods: We created a full thickness defect in the trochlear groove of thirty-six bilateral knees of eighteen mature male rabbits. The knees were randomly divided into six groups (group I: untreated control, group II: PRP, group III: PRF, group IV: Gelatin+SDF1, group V: PRP+SDF1, and group VI: PRF+SDF1. After four weeks, the tissue specimens were evaluated by macroscopic examination and histological grading, immunofluorescent staining for collagen type II, and analyzed for cartilage marker genes by real-time PCR. The data were compared using statistical methods (SPSS 20, Kruskal-Wallis test, Bonferroni post hoc test and P<0.05. Results: Macroscopic evaluations revealed that international cartilage repair society (ICRS scores of the PRF+SDF1 group were higher than other groups. Microscopic analysis showed that the ICRS score of the PRP group was significantly lower than other groups. Immunofluorescent staining for collagen II demonstrated a remarkable distribution of type II collagen in the Gel+SDF1, PRP+SDF1 and PRF+SDF1 groups compared with other groups. Real-time PCR analysis revealed that mRNA expression of SOX9 and aggrecan were significantly greater in the PRF+SDF1, PRP+SDF1, Gel+SDF1 and PRF groups than the control group (P<0.05. Conclusion: Our results indicate that implantation of PRF scaffold containing SDF1 led to the greatest evaluation scores of full-thickness lesions in rabbits.

    Recent literature has shown that full-thickness wounds, devoid of the stem cell niche, can subsequently be reconstructed with functional skin elements following migration of the LGR6 epithelial stem cell into the wound bed. In this study, the authors use a variety of LGR6 epithelial stem cell-seeded scaffolds to determine therapeutic utility and regenerative potential in the immediate reconstruction of full-thickness wounds. Isolated LGR6 epithelial stem cells were seeded onto a spectrum of acellular matrices and monitored in both in vitro and in vivo settings to determine their relative capacity to regenerate tissues and heal wounds. Wound beds containing LGR6 stem cell-seeded scaffolds showed significantly augmented rates of healing, epithelialization, and hair growth compared with controls. Gene and proteomic expression studies indicate that LGR6 stem cell-seeded constructs up-regulate WNT, epidermal growth factor, and angiogenesis pathways. Finally, the addition of stromal vascular fraction to LGR6 stem cell-seeded constructs induces polarized tissue formation, nascent hair growth, and angiogenesis within wounds. LGR6 stem cells are able to undergo proliferation, differentiation, and migration following seeding onto a variety of collagen-based scaffolding. In addition, deployment of these constructs induces epithelialization, hair growth, and angiogenesis within wound beds. The addition of stromal vascular fraction to LGR6 stem cell-containing scaffolds initiated an early form of tissue polarization, providing for the first time a clinically applicable stem cell-based construct that is capable of the repair of full-thickness wounds and hair regeneration.

    Full Text Available Objective. To comparatively analyze the efficiency of methods for extracorporeal detoxification (ED of the body in abdominal sepsis (AS and to choose the optimum detoxifying methods in relation to the level of endotoxicosis.Material and methods. 56 patients (41 males and 15 females; mean age 39.4±12.2 years with surgical abdominal infection of various genesis, complicated by the development of sepsis whose treatment included ED methods, were examined. The level of intoxication and the efficiency of detoxification were evaluated by general clinical and biochemical blood parameters, the leukocytic intoxication index, the levels of low and medium molecular-weight substances in the body’s media. Hemosorption, plasmapheresis, hemodialysis, hemodiafiltration, and hemofiltration were used for detoxification.Results. Surgical abdominal infection is accompanied by endotoxemia that has no clear nosological specificity, but it depends on the pattern of a clinical course of the disease and is most pronounced in the septic syndrome. In AS, 80.4% of the patients are observed to have an irreversible decompensation phase and a terminal degree of endotoxicosis, which require detoxification. The use of different ED methods according to the level of intoxication may reduce the level of endotoxicosis and yield a persistent beneficial effect in 85.2% of cases of its application. Conclusion. Filtration and dialysis techniques (hemodialysis, hemofiltration, and hemodiafiltration are the methods of choice in AS. Hemosorption and plasmapheresis may be recommended for use at the early stages of endotoxicosis development and in preserved renal excretory function.

    Full Text Available BACKGROUND In the recent times there has been increased incidence of abdominal trauma cases due to several causes. Quick and prompt intervention is needed to decrease the mortality of the patients. So we conducted a study to assess the cause and the management of abdominal trauma cases in our institution. The aim of this study was to know the incidence of blunt and penetrating injuries and their causes, age and sex incidence, importance of various investigations, mode of treatment offered and post-operative complications. To study the cause of death and evolve better management. MATERIALS AND METHODS The present study comprises of patients admitted to and operated in various surgical units in the Department of Surgery at Government General Hospital, attached to Guntur Medical College Guntur, from August 2014 to October 2016. RESULTS Increase incidence seen in age group 20-29 years (30%. Male predominance 77.5%. Mechanism of injury–road traffic accidents 65%. Isolated organ injury–colon and rectum 40%. Other associated injuries–chest injuries with rib fractures 7.5%. Complications–wound infection 17.5%. Duration of hospital stay 8–14 days. Bowel injury management–closure of perforation 84.6%. Resection anastomosis 15.38%. CONCLUSION Thorough clinical examination, diagnostic paracentesis, plain X-ray erect abdomen and ultrasound proved to be very helpful in the diagnosis of intra-abdominal injuries. Spleen is the commonest organ involved in blunt trauma and colon is the commonly injured organ in penetrating abdominal trauma, many patients have associated extremity and axial skeleton injuries. With advances in diagnosis and intensive care technologies, most patients of solid visceral injuries with hemodynamic stability can be managed conservatively. Surgical site infection is the most common complication following surgery. The mortality is high; reason might be patient reaching the hospital late, high incidence of postoperative septic

    Full Text Available Introduction. This report presents a primary Mullerian carcinosarcoma localized in the incisional hernia i.e. anterior abdominal wall. There is no data in the literature about this localization of extragenital Mullerian carcinosarcoma. Case Outline. The patient had previous medical history of right-sided ovarian cystadenocarcinoma managed by hysterectomy, bilateral ovariectomy and chemotherapy. An incisional hernia occurred 1 year after the operation and Mullerian carcinosarcoma at the right border of the incisional hernia 16 years later. There was no tumor spreading into the abdominal cavity and pelvis. Full thickness of the abdominal wall resection and coexisting incisional hernia resulted in a large 25x20 cm abdominal wall defect managed by the modified components separation technique and implanting meshes. Conclusion. Major abdominal wall resection and abdominal wall reconstruction using the modified components separation technique reinforced with meshes could be one of possible solutions in the surgical treatment of primary malignant mixed Mullerian tumor localized in the abdominal wall.

    Management of full-thickness facial burns remains one of the greatest challenges. Controversy exists among surgeons regarding the use of early excision for facial burns. Unfortunately, delayed excision of deeper burns often results in more scarring and subsequent reconstruction becomes more difficult. A collagen-elastin matrix is used to improve the quality of the reconstructed skin, to reduce scarring and to prevent wound contraction. It serves as a foundation for split thickness skin graft and enhances short and long-term results. We report the usage of a collagen-elastin matrix during single-step wound closure technique of severe full-thickness facial burns in 15 children with large burned body surface area, and also we review the literature about pediatric facial burns. There were 15 pediatric patients with severe facial burns, 8 girls and 7 boys ranging in age from 10 months to 12 years, mean age 7 years and 6 months old. The facial burn surface area (FBSA) among the patients includes seven patients with 100%, five with 75%, and three with 50%. The average total body surface area (TBSA) for the patients was 72%, ranging between 50 and 90%. 5 of the patients' admissions were late, more than four days after burns while the rest of the patients were admitted within the first four days (acute admission time). The burns were caused by flame in eight of the patients, bomb blast in four, and scalding in three. All patients were treated by the simultaneous application of the collagen-elastin matrix and an unmeshed split thickness skin graft at Turgut Özal Medical Center, Pediatric Burn Center, Malatya, Turkey. After the treatment only two patients needed a second operation for revision of the grafts. All grafts transplanted to the face survived. The average Vancouver scar scales (VSS) were 2.55±1.42, ranging between one and six, in the first 10 of 15 patients at the end of 6 months postoperatively. VSS measurements of the last 5 patients were not taken since the 6

  19. Intra-abdominal hypertension in acute pancreatitis.

    Science.gov (United States)

    De Waele, Jan J; Leppäniemi, Ari K

    2009-06-01

    The incidence of intra-abdominal hypertension (IAH) in patients with severe acute pancreatitis (SAP) is approximately 60-80%. It is usually an early phenomenon, partly related to the effects of the inflammatory process, causing retroperitoneal edema, fluid collections, ascites, and ileus, and partly iatrogenic, resulting from aggressive fluid resuscitation. It also can manifest at a later stage, often associated with local pancreatic complications. IAH is associated with impaired organ dysfunction, especially of the cardiovascular, respiratory, and renal systems. Using current definitions, the incidence of the clinical manifestation, abdominal compartment syndrome (ACS), has been reported as 27% in the largest study so far. Despite several intervention options, the mortality in patients developing ACS remains high: 50-75%. Prevention with judicious use of crystalloids is important, and nonsurgical interventions, such as nasogastric decompression, short-term use of neuromuscular blockers, removal of fluid by extracorporeal techniques, and percutaneous drainage of ascites should be instituted early. The indications for surgical decompression are still not clearly defined, but undoubtedly some patients benefit from it. It can be achieved with full-thickness laparostomy (midline or transverse subcostal) or through a subcutaneous linea alba fasciotomy. Despite the improvement in physiological variables and significant decrease in IAP, the effects of surgical decompression on organ function and outcome are less clear. Because of the significant morbidity associated with surgical decompression and the management of the ensuing open abdomen, more research is needed to define better the appropriate indications and techniques for surgical intervention.

    Full Text Available Introduction: It appears that the level of fear of movement changes deep trunk muscle activity in the patients with low back pain (LBP. There is no study to investigate the relationship between deep trunk muscle activity and fear of movement in the patients with LBP. Thus, the purpose of this study was to assess the relationship between abdominal muscle activity and pain, disability and fear of movement during standing postural tasks in females with chronic nonspecific LBP. Materials and Methods: Forty four females participated were asked to maintain their balance during standing on the platform stability levels of Biodex Balance System (BBS. Concurrently, ultrasonography (US data about abdominal muscles thickness measurement were transferred and saved to process offline. The pain intensity, disability and fear of movement were assessed by valid scales and questionnaire. Results: There was not significant correlation between abdominal muscle thickness changes and pain and disability intensity (P>0.05, while significant and inverse correlation between deep abdominal muscle thickness changes and fear of movement was observed in the patients (P<0.05, although this correlation is weak (r= -0.36- -0.32. Conclusion: It seems that increases in fear of movement decrease significantly deep abdominal muscles activity in the patients with LBP. This relationship demonstrates the importance of cognitive behavioral therapy and controlling fear of movement on improvement of deep abdominal muscle activity in the patients with LBP

    The purpose of this study was to examine 5-year outcomes in a prospective cohort of patients previously enrolled in a nonoperative rotator cuff tear treatment program. Patients with chronic (>3 months), full-thickness rotator cuff tears (demonstrated on imaging) who were referred to 1 of 2 senior shoulder surgeons were enrolled in the study between October 2008 and September 2010. They participated in a comprehensive, nonoperative, home-based treatment program. After 3 months, the outcome in these patients was defined as "successful" or "failed." Patients in the successful group were essentially asymptomatic and did not require surgery. Patients in the failed group were symptomatic and consented to undergo surgical repair. All patients were followed up at 1 year, 2 years, and 5 or more years. At 5 or more years, all patients were contacted for follow-up; the response rate was 84%. Approximately 75% of patients remained successfully treated with nonoperative treatment at 5 years and reported a mean rotator cuff quality-of-life index score of 83 of 100 (SD, 16). Furthermore, between 2 and 5 years, only 3 patients who had previously been defined as having a successful outcome became more symptomatic and underwent surgical rotator cuff repair. Those in whom nonoperative treatment had failed and who underwent surgical repair had a mean rotator cuff quality-of-life index score of 89 (SD, 11) at 5-year follow-up. The operative and nonoperative groups at 5-year follow-up were not significantly different (P = .11). Nonoperative treatment is an effective and lasting option for many patients with a chronic, full-thickness rotator cuff tear. While some clinicians may argue that nonoperative treatment delays inevitable surgical repair, our study shows that patients can do very well over time.

    Purpose To determine the degree of preoperative fatty degeneration within muscles, postoperative longitudinal changes in fatty degeneration, and differences in fatty degeneration between patients with full-thickness supraspinatus tears who do and those who do not experience a retear after surgery. Materials and Methods This prospective study had institutional review board approval and was conducted in accordance with the Committee for Human Research. Informed consent was obtained. Fifty patients with full-thickness supraspinatus tears (18 men, 32 women; mean age, 67.0 years ± 8.0; age range, 41-91 years) were recruited. The degrees of preoperative and postoperative fatty degeneration were quantified by using a two-point Dixon magnetic resonance (MR) imaging sequence; two radiologists measured the mean signal intensity on in-phase [S(In)] and fat [S(Fat)] images. Estimates of fatty degeneration were calculated with "fat fraction" values by using the formula S(Fat)/S(In) within the supraspinatus, infraspinatus, and subscapularis muscles at baseline preoperative and at postoperative 1-year follow-up MR imaging. Preoperative fat fractions in the failed-repair group and the intact-repair group were compared by using the Mann-Whitney U test. Results The preoperative fat fractions in the supraspinatus muscle were significantly higher in the failed-repair group than in the intact-repair group (37.0% vs 19.5%, P muscle tended to progress at 1 year postoperatively in only the failed-repair group. Conclusion MR imaging quantification of preoperative fat fractions by using a two-point Dixon sequence within the rotator cuff muscles may be a viable method for predicting postoperative retear.

    The aim of this study was to compare the effect of diet and an abdominal resistance training program to diet alone on abdominal subcutaneous fat thickness and waist circumference of overweight and obese women. This randomized clinical trial included 40 overweight and obese women randomly divided into 2 groups: diet only and diet combined with 12 weeks of abdominal resistance training. Waist and hip circumferences and abdominal skin folds of the subjects were measured at the beginning and 12 weeks after the interventions. In addition, abdominal subcutaneous fat thickness of the subjects was measured using ultrasonography. Percentage body fat and lean body mass of all the subjects were also measured using a bioelectric impedance device. After 12 weeks of intervention, the weight of participants in both groups decreased; but the difference between the 2 groups was not significant (P = .45). Similarly, other variables including abdominal subcutaneous fat, waist circumference, hip circumference, body mass index, body fat percentage, and skin fold thickness were reduced in both groups; but there were no significant differences between the groups. This study found that abdominal resistance training besides diet did not reduce abdominal subcutaneous fat thickness compared to diet alone in overweight or obese women.

    2009-04-01

    Full Text Available Abstract Penetrating abdominal injuries have been traditionally managed by routine laparotomy. New understanding of trajectories, potential for organ injury, and correlation with advanced radiographic imaging has allowed a shift towards non-operative management of appropriate cases. Although a selective approach has been established for stab wounds, the management of abdominal gunshot wounds remains a matter of controversy. In this chapter we describe the rationale and methodology of selecting patients for non-operative management. We also discuss additional controversial issues, as related to antibiotic prophylaxis, management of asymptomatic thoracoabdominal injuries, and the use of colostomy vs. primary repair for colon injuries.

    Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management.

    Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and <50% of the thickness differences in all muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Appendecitis is one of the most frequent surgeries. Inflammation of appendix may be due to variable causes such as fecalit, hypertrophy of Peyer’s plaques, seeds of fruits and parasites. In this study we presented an uncommon type of appendicitis which occurred after abdominal blunt trauma. In this article three children present who involved acute appendicitis after blunt abdominal trauma. These patients were 2 boys (5 and 6-year-old and one girl (8-year-old who after blunt abdominal trauma admitted to the hospital with abdominal pain and symptoms of acute abdomen and appendectomy had been done for them.Trauma can induce intramural hematoma at appendix process and may cause appendicitis. Therefore, physicians should be aware of appendicitis after blunt abdominal trauma

    2018-01-01

    Abdominal pain is one of the common symptoms reported by children in urgent care clinics. While most children tend to have self-limiting conditions, the treating pediatrician should watch out for underlying serious causes like intestinal obstruction and perforation peritonitis, which require immediate referral to an emergency department (ED). Abdominal pain may be secondary to surgical or non-surgical causes, and will differ as per the age of the child. The common etiologies for abdominal pain presenting to an urgent care clinic are acute gastro-enteritis, constipation and functional abdominal pain; however, a variety of extra-abdominal conditions may also present as abdominal pain. Meticulous history taking and physical examination are the best tools for diagnosis, while investigations have a limited role in treating benign etiologies.

    One crucial issue in stem cell therapy used for tissue repair is often the lack of selective carriers to deliver stem cells to the site of injury where the native extracellular matrix is pathologically damaged or lost. Therefore, it is necessary to develop a biomaterial that is permissive to stem cells and is suitable to replace injured or missing matrix. The major aim of this study is to investigate the potential of an RGD-containing elastin-like polypeptide (REP) with the structure TGPG[VGRGD(VGVPG)6]20WPC to engraft adipose stem cells (ASC) to full-thickness excisional wounds in mice. We implanted REP into the wound defects via body temperature-induced in situ aggregation. Engrafted REP exhibited a half-life of 2.6days in the wounds and did not elicit any pathological immune responses. REP itself significantly accelerated wound closure and reepithelialization and upregulated the expression of dermal tissue components. A combined administration of REP and ASC formed a hydrogel-like ASC/REP composite, which provided better neovascularization than the use of ASCs alone and increased the viability of transplanted ASC, improving overall wound healing. In vitro and in vivo mechanistic investigations suggested that REP enhances ASC survival at least in part via the Fak/Src adhesion-induced upregulation of Mek/Erk and PI3K/Akt survival pathways. We conclude that REP is a promising therapeutic agent for the improvement of stem cell-based therapy for enhanced tissue regeneration and repair. Copyright © 2016 Elsevier B.V. All rights reserved.

  2. Correlation between intra-abdominal pressure and pulmonary volumes after superior and inferior abdominal surgery

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available OBJECTIVE:Patients undergoing abdominal surgery are at risk for pulmonary complications. The principal cause of postoperative pulmonary complications is a significant reduction in pulmonary volumes (FEV1 and FVC to approximately 65-70% of the predicted value. Another frequent occurrence after abdominal surgery is increased intra-abdominal pressure. The aim of this study was to correlate changes in pulmonary volumes with the values of intra-abdominal pressure after abdominal surgery, according to the surgical incision in the abdomen (superior or inferior.METHODS:We prospectively evaluated 60 patients who underwent elective open abdominal surgery with a surgical time greater than 240 minutes. Patients were evaluated before surgery and on the 3rd postoperative day. Spirometry was assessed by maximal respiratory maneuvers and flow-volume curves. Intra-abdominal pressure was measured in the postoperative period using the bladder technique.RESULTS:The mean age of the patients was 56±13 years, and 41.6% 25 were female; 50 patients (83.3% had malignant disease. The patients were divided into two groups according to the surgical incision (superior or inferior. The lung volumes in the preoperative period showed no abnormalities. After surgery, there was a significant reduction in both FEV1 (1.6±0.6 L and FVC (2.0±0.7 L with maintenance of FEV1/FVC of 0.8±0.2 in both groups. The maximum intra-abdominal pressure values were similar (p= 0.59 for the two groups. There was no association between pulmonary volumes and intra-abdominal pressure measured in any of the groups analyzed.CONCLUSIONS:Our results show that superior and inferior abdominal surgery determines hypoventilation, unrelated to increased intra-abdominal pressure. Patients at high risk of pulmonary complications should receive respiratory care even if undergoing inferior abdominal surgery.

    To test the accuracy and reproducibility of ultrasound and computed tomography (CT) for the quantification of abdominal fat in correlation with the anthropometric, clinical, and biochemical assessments. Using ultrasound and CT, we determined the thickness of subcutaneous and intra-abdominal fat in 101 subjects-of whom 39 (38.6%) were men and 62 (61.4%) were women-with a mean age of 66.3 years (60-80 years). The ultrasound data were correlated with the anthropometric, clinical, and biochemical parameters, as well as with the areas measured by abdominal CT. Intra-abdominal thickness was the variable for which the correlation with the areas of abdominal fat was strongest (i.e., the correlation coefficient was highest). We also tested the reproducibility of ultrasound and CT for the assessment of abdominal fat and found that CT measurements of abdominal fat showed greater reproducibility, having higher intraobserver and interobserver reliability than had the ultrasound measurements. There was a significant correlation between ultrasound and CT, with a correlation coefficient of 0.71. In the assessment of abdominal fat, the intraobserver and interobserver reliability were greater for CT than for ultrasound, although both methods showed high accuracy and good reproducibility.

    Full text: Heterotopic bone formation within the abdominal cavity is a rare complication of the posttraumatic abdominal surgery. There are only few cases reported in the medical literature and most of them involve the mesentery or the abdominal wall. A case of 49y-old men is presented who developed intraabdominal heterotopic ossifications as a consequence of numeral exploratory laparotomies performed after a blunt abdominal trauma. The condition was detected during the follow-up MDCT 11 months later. The case is of interest because of the rarity of the condition and the diffuse character of the calcifications in the abdominal structures, which could pose some differential diagnostic difficulties

    2015-09-01

    Full Text Available Abdominal fat in broiler carcass is considered as a waste and its existence reduces the carcass quality. Abdominal fat deposition is affected by several factors such as genetic, nutrition, feed, sex, age and environment. Reducing abdominal fat deposition can be carried out by regulating the nutrient intake to ensure that no excessive nutrient was consumed. Nutrition effects to reduce abdominal fat deposition are associated with nutrient concentration of ration and quantity of daily feed intake. Daily nutrient intake can be limited, especially through restricted feeding. It is concluded that an appropriate feeding management can reduce abdominal fat deposition in broiler.

    Full Text Available Avaliou-se a influência da cola de fibrina, derivada do veneno de serpente, na fixação e integração de enxerto de pele. Foram utilizados nove cães, sem raça definida, com peso médio de 15kg. Foi induzida ferida de 4×4cm de área, na face crânio-proximal dos antebraços direito e esquerdo. Um enxerto de espessura total foi colhido da região torácica e expandido por meio de expansor de pele. No membro direito o enxerto foi estabilizado no leito receptor por meio de pontos isolados simples; no esquerdo foi fixado pela aplicação de cola de fibrina e oito pontos de sutura. O sítio doador foi fechado empregando-se retalho cutâneo bipediculado. As bandagens do leito receptor foram oclusivas e não aderentes e aplicou-se pomada de neomicina com bacitracina. A troca de bandagens ocorreu diariamente até o sétimo dia de pós-operatório e, posteriormente, a cada três dias. A área de sobrevivência do enxerto foi obtida pela subtração das áreas não viáveis e total medidas com fotomicroscópio Nikon conectado a um sistema de análise de imagem KS-300 aos três, sete, 15 e 30 dias de pós-operatório. Para a avaliação microscópica, a área do enxerto foi colhida em três animais aos sete, 15 e 30 dias de pós-operatório. Não houve diferença entre momentos de avaliação e técnicas de fixação quanto à área de enxerto viável. Os enxertos fixados com cola apresentaram estágio de reparação mais avançado em todos os momentos. Concluiu-se que a cola de fibrina derivada do veneno de serpente tem moderado poder adesivo e, pela análise microscópica, favorece a integração do enxerto cutâneo em malha de espessura total.The purpose of this study was to evaluate the efficiency of fibrin glue, derived from snake venom, on fixation and integration of skin graft.

    The suture bridge (SB) technique and conventional double-row (DR) are both effective in repair of full-thickness rotator cuff tears . However, increasing numbers of scholars believe that the SB technique produces better results than conventional DR because of the higher bone-tendon contact area and pressure. However, The clinical outcomes have been mixed and little direct evidence has been supplied in vivo. This study was designed using the SB and DR techniques to determine which is the better technique. Sixty-four New Zealand white rabbits were randomly divided into 2 groups, the SB group and DR group. SB and DR were then used to repair their rotator cuff tears. Rabbits were then sacrificed at the 2(nd), 4(th), or 8(th) week after surgery and a histological comparison was made. The biomechanical comparison was made at the 8(th) week. The load to failure of the SB group was 134.59 ± 17.69 N at the 8(th) postoperative week, and that was significantly higher than in the DR group (103.83 ± 6.62, P = 0.001), but both repair groups remained lower than in the control group (199.25 ± 14.81). Histological evaluation showed that both the SB and DR groups healed at the bone-tendon interface. But there were subtle differences between the two groups in the structure and morphology of collagen fibers and cartilage cells at bone-tendon interface. In general, the collagen fibers of the SB group were more compact than those of the DR group at all times tested. At the 4(th) and 8(th) weeks, the collagen fibers and cartilage cells in the SB group were arranged in a column modality, but those in the DR group were distributed horizontally. The SB technique facilitated healing more effectively than the conventional DR technique. The difference in morphology of collagen fibers and cartilage cells may be related to the difference in bone-tendon contact pressure.

Si bien los principios de la reconstrucción del tórax exigen una escisión amplia de la lesión, desbridamiento de los tejidos desvitalizados o irradiados y control de la infección local, dichas actuaciones no podrían abordarse con seguridad si no dispusiéramos de un amplio arsenal de técnicas reconstructivas, capaces de aportar tejidos sanos y bien vascularizados o voluminosos y amplios en superficie, junto con soportes rígidos mediante materiales aloplásticos. Gracias a estos avances, en la mayoría de los casos conseguimos el objetivo con sólo una intervención, cuando hace unos años necesitábamos varios procedimientos quirúrgicos. Presentamos una muestra variada de la experiencia de nuestro Servicio en el tratamiento de grandes defectos del tórax, en el que resumimos las distintas posibilidades que podemos encontrar en la práctica clínica diaria, y las soluciones que mejor se adaptan a las mismas.Reconstruction of full thickness defects on the chest wall is controversial and require the use of complex techniques that combine autologous tissue and/or alloplastic materials. Thus it is a challenge for plastic surgeons since it needs a suitable and functional reconstruction.

    Chronic abdominal wall pain is a poorly recognized clinical problem despite being an important element in the differential diagnosis of abdominal pain. This review is based on pertinent articles that were retrieved by a selective search in PubMed and EMBASE employing the terms "abdominal wall pain" and "cutaneous nerve entrapment syndrome," as well as on the authors' clinical experience. In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.

    Full Text Available Schistosomiasis presenting as an abdominal mass with chronic pain in a child is not common. This report presents case of child presenting with schistosomiasis presenting as an abdominal mass with chronic pain. Abdominal ultrasonography did not particularly contribute to definitive pre-operative diagnosis. However, pathological examination of surgical specimen confirmed Schistosoma mansoni eggs in the biospy. A decrease in the mass volume was noticed under medical treatment (Biltricide. The aim of this report was to intimate clinicians on possible abdominal schistosomiasis as differential diagnosis of childhood abdominal mass. This is a clarion call for a high index of suspicion of childhood abdominal schistosomiasis in children presenting with abdominal mass in a tropical setting.

  12. CT of abdominal abscesses

    The imaging search for a suspected abdominal abscess is common in hospitalized patients, especially after recent abdominal surgery. This paper examines the role of CT in the detection, localization, and treatment of abdominal abscess. The accuracy, limitations, and technical aspects of CT in this clinical setting are discussed. The diagnosis of an abscess is based on the demonstration of a circumscribed abnormal fluid collection. Although percutaneous aspiration with gram stain and culture is usually indicated to differentiate abscess from other fluid collections, the CT-based detection of extraluminal gas bubbles makes the diagnosis of an abscess highly likely. CT is compared with conventional radiographic studies, US, and radio-nuclide imaging. Specific CT and clinical features of abscesses in the following sites are emphasized: subphrenic space, liver, pancreas, kidneys, psoas muscle, appendix, and colonic diverticula. Most abdominal abscesses can be successfully treated with percutaneous drainage techniques. The techniques, results, and limitations of percutaneous abscess drainage are reviewed

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis.

    Abdominal wall sheathing tissues are commonly involved in hernia formation. However, there is very limited work studying mechanics of all tissues from the same donor which prevents a complete understanding of the abdominal wall behavior and the differences in these tissues. The aim of this study was to investigate the differences between the mechanical properties of the linea alba and the anterior and posterior rectus sheaths from a macroscopic point of view. Eight full-thickness human anterior abdominal walls of both genders were collected and longitudinal and transverse samples were harvested from the three sheathing connective tissues. The total of 398 uniaxial tensile tests was conducted and the mechanical characteristics of the behavior (tangent rigidities for small and large deformations) were determined. Statistical comparisons highlighted heterogeneity and non-linearity in behavior of the three tissues under both small and large deformations. High anisotropy was observed under small and large deformations with higher stress in the transverse direction. Variabilities in the mechanical properties of the linea alba according to the gender and location were also identified. Finally, data dispersion correlated with microstructure revealed that macroscopic characterization is not sufficient to fully describe behavior. Microstructure consideration is needed. These results provide a better understanding of the mechanical behavior of the abdominal wall sheathing tissues as well as the directions for microstructure-based constitutive model.

  1. Hernia Following Blunt Abdominal Trauma

    Directory of Open Access Journals (Sweden)

    2009-10-01

    Full Text Available Traumatic abdominal wall hernia is a rare type of hernia, which follows blunt trauma to the abdomen, where disruption of the musculature and fascia occurs with the overlying skin remaining intact. Diagnosis of this problem is very difficult and delayed. Traumatic hernia is often diagnosed during laparatomy or laparascopy, but CT scan also has a role in distinguishing this pathology. Delay in diagnosis is very dangerous and can result in gangrene and necrosis of the organs in the hernia. The case report of a 35 years old man with liftruck blunt trauma is reported. His vital signs were stable. On physical examination, tenderness of RUQ was seen. He underwent Dpl for suspected hemoprotein. Dpl was followed up by laparatomy. Laparatomy revealed that the transverse and ascending colon partially herniated in the abdominal wall defect. The colon was reduced in the abdomen and repair of abdominal hernia was done. The patient was discharged after 5 day. The etiology, pathogenesis and management are discussed.

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition. Copyright © 2016 SERAM.

    2011-05-01

    Full Text Available Burns account for a significant proportion of injuries, and of these the face, neck, and anterior torso are commonly affected. Burn scars remain a lasting reminder of the insult both for the patient and the outside world. There is little doubt that the change in appearance and the limitation imposed by a burn scar contribute to negative body image. Treatment of hypertrophic scars in the neck has been quite challenging if there is no intact tissue for local flaps. So application of full-thickness skin grafts could be of great value. We applied full-thickness grafts obtained from lower abdominal skin for treatment of severe neck contractures in four patients when other treatment modalities such as local flaps could not be used. Full-thickness skin graft of the neck is a safe and reliable treatment option with fairly good functional and aesthetic results. It has little donor site morbidity in spite of providing a large surface area of full-thickness skin.

    Abdominal pregnancy, a rare diagnosis, belongs to the ectopic pregnancy group, the leading cause of pregnancy related exitus. The positive diagnosis is very difficult to establish most often in an acute setting, leading to a staggering percent of feto-maternal morbidity and mortality. We present the case of 26-weeks-old abdominal pregnancy with partial feto-placental detachment in a patient, after hysteroscopy and in vitro fertilization, which until the acute symptoms that led to emergency laparotomy went unrecognized. The patient recovered completely and satisfactorily after surgery and, due to the high risk of uterine rupture with regard to a second pregnancy, opted for a surrogate mother. Abdominal pregnancy can be regarded as a difficult to establish diagnosis, with a greater chance in case of increased awareness. It is compulsory to be well informed in order not to be surprised by the diagnosis and to apply the correct treatment immediately as the morbidity and mortality rate is elevated.

    Full Text Available Aim: Abdominal tuberculosis is an uncommon form of extrapulmonary infection. In this study, we aimed to highlight the nonspecific clinical presentations and diagnostic difficulties of abdominal tuberculosis. Material and Method: Clinical features, diagnostic methods, and the therapeutic outcomes of 49 patients diagnosed as abdominal tuberculosis between 2003 and 2014 were retrospectively analyzed. Results: The patients were classified into four subgroups including peritoneal (28, nodal (14, intestinal (5, and solid organ tuberculosis (2. The most frequent symptoms were abdominal pain, abdominal distention and fatique. Ascites appeared to be the most frequent clinical finding. Ascites and enlarged abdominal lymph nodes were the most frequent findings on ultrasonography and tomography. Diagnosis of abdominal tuberculosis was mainly depended on histopathology of ascitic fluid and biopsies from peritoneum, abdominal lymph nodes or colonoscopic materials. Forty patients healed with standart 6-month therapy while extended treatment for 9-12 months was needed in 8 whom had discontinued drug therapy and had persistent symptoms and signs. One patient died within the treatment period due to disseminated infection. Discussion: The diagnosis of abdominal tuberculosis is often difficult due to diverse clinical presentations. The presence of ascites, personal/familial/contact history of tuberculosis, and coexisting active extraabdominal tuberculosis are the most significant marks in diagnosis. Diagnostic laparoscopy and tissue sampling seem to be the best diagnostic approach for abdominal tuberculosis.

    Abdominal paracentesis and thoracocentesis are common bedside procedures with diagnostic, therapeutic and palliative roles. We describe a useful and familiar a useful and familiar technique with the use of a multiple lumen catheter commonly used for central venous line insertion for drainage of ascites or moderate to large pleural effusions. The use of a multiple lumen catheter allows easier and more rapid aspiration of fluid with a smaller probability of the side holes being blocked as compared to the standard needle or single catheter methods. This is particularly useful in situations where the dedicated commercial kits for thoracocentesis and abdominal paracentesis are not readily available.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

    Purpose: To evaluate CT in the diagnosis of abdominal abscess in children. Methods: Analysis of CT manifestations in 23 cases proved by operation and needle aspiration. Causes: acute appendicitis 13 cases, ascending colon perforation 1 case, Meckel diverticulitis 2 cases, cause obscured 7 cases. Bolus injection of contrast medium was given in 19 cases. Results: The CT value had no relationship to the course of disease and type of bacteria, amount of abscess had positive relevance relative with course of illness. Air-fluid level or scattered gas bubbles was seen in abscesses in 52%; little calcified plague was present in 22%. All cases presented nonhomogeneous thick wall enhancement after one week of illness. Conclusion: The characteristic CT features of intra-abdominal abscess were the presence of air and little calcified plague shadow; a large air-fluid level was indicative of fistula, while the absence of air in the abscess can not exclude fistula

  15. Functional abdominal pain.

    Science.gov (United States)

    Grover, Madhusudan; Drossman, Douglas A

    2010-10-01

    Functional abdominal pain syndrome (FAPS) is a relatively less common functional gastrointestinal (GI) disorder defined by the presence of constant or frequently recurring abdominal pain that is not associated with eating, change in bowel habits, or menstrual periods (Drossman Gastroenterology 130:1377-1390, 2006), which points to a more centrally targeted (spinal and supraspinal) basis for the symptoms. However, FAPS is frequently confused with irritable bowel syndrome and other functional GI disorders in which abdominal pain is associated with eating and bowel movements. FAPS also differs from chronic abdominal pain associated with entities such as chronic pancreatitis or chronic inflammatory bowel disease, in which the pain is associated with peripherally acting factors (eg, gut inflammation or injury). Given the central contribution to the pain experience, concomitant psychosocial disturbances are common and strongly influence the clinical expression of FAPS, which also by definition is associated with loss of daily functioning. These factors make it critical to use a biopsychosocial construct to understand and manage FAPS, because gut-directed treatments are usually not successful in managing this condition.

    LENUS (Irish Health Repository)

    Murphy, Kevin P

    2014-06-01

    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

    Full Text Available Acute appendicitis is a common disease in clinical practice; some well-defined causes include luminal obstruction by fecoliths, lymphoid hyperplasia, foreign bodies and intestinal parasites. Closed abdominal trauma has been associated as an etiological factor, although, their causal relationship is still unclear. This paper presents the case of a patient with appendicitis after a closed abdominal trauma.

    Full Text Available Minimal invasive surgery has become the standard of care for operations involving the thoracic and abdominal cavities for all ages. Laparoscopic complications can occur as well as more invasive surgical procedures and we can classify them into non-specific and specific. Our goal is to analyze the most influential available scientific literature and to expose important and recognized advices in order to reduce these complications. We examined the mechanism, risk factors, treatment and tried to outline how to prevent two major abdominal wall complications related to laparoscopy: bleeding and port site herniation .

    Full Text Available In recent years, the concept of comprehensive treatment for military trauma has been comprehensively updated. The application of damage control surgery has significantly improved the clinical outcome of severe abdominal injury. With appropriate surgical intervention, post-trauma fluid resuscitation plays an increasingly important role in the treatment of abdominal injury. The damage control resuscitation strategy addresses the importance of permissive hypotension and haemostatic resuscitation for patients with severe trauma, under the guidance of damage control surgical principle.

    Full Text Available Isolated perforation of the jejunum, following blunt abdominaltrauma, is extremely rare. These injuries aredifficult to diagnose because initial clinical signs are frequentlynonspecific and a delay in treatment increasesmortality and morbidity of the patients. Conventional radiogramsare often inadequate for diagnosing this subsetof trauma. For an accurate and timely diagnosis, thepossibility of bowel perforation and the need for repeatedexaminations should be kept in mind. Herein, we presenta 28-year-old man with isolated jejunal perforation followingblunt abdominal trauma.Key words: Blunt abdominal trauma, isolated jejunal perforation,early diagnosis

    Full Text Available BACKGROUND Blunt abdominal trauma is an emergency and is associated with significant morbidity and mortality. The aim of the study is to study incidence, demographic profile, epidemiological factors, mechanism of trauma, treatment modalities, associated injuries, postoperative complications and morbidity and mortality. MATERIALS AND METHODS A retrospective analysis of 72 patients of blunt abdominal trauma who were admitted in government general hospital between May 2013 to April 2015 in Department of General Surgery, Government General Hospital, Guntur, with in a span of 24 months were studied. Demographic data, mechanism of trauma, management and outcome were studied. RESULTS Most of the patients in our study were in the age group of 21-30 years. Spleen was the commonest organ involved and most common procedure performed was splenectomy. Most common extra-abdominal injury was rib fractures. Wound infection was the commonest complication. CONCLUSION Initial resuscitative measures, thorough clinical examination and correct diagnosis forms the vital part of the management. FAST is more useful in blunt abdominal trauma patients who are unstable. X-ray revealed 100% accuracy in hollow viscous perforation in blunt abdominal trauma patients. CT abdomen is more useful in stable patients. Definitive indication for laparotomy was haemodynamic instability and peritonitis. Associated injuries influenced morbidity and mortality. Early diagnosis and prompt treatment can save many lives.

    2017-01-01

    Full Text Available Cystic fibrosis (CF is a multisystem disease with a range of abdominal manifestations including those involving the liver, pancreas, and kidneys. Recent advances in management of the respiratory complications of the disease has led to a greater life expectancy in patients with CF. Subsequently, there is increasing focus on the impact of abdominal disease on quality of life and survival. Liver cirrhosis is the most important extrapulmonary cause of death in CF, yet significant challenges remain in the diagnosis of CF related liver disease. The capacity to predict those patients at risk of developing cirrhosis remains a significant challenge. We review representative abdominal imaging findings in patients with CF selected from the records of two academic health centres, with a view to increasing familiarity with the abdominal manifestations of the disease. We review their presentation and expected imaging findings, with a focus on the challenges facing diagnosis of the hepatic manifestations of the disease. An increased familiarity with these abdominal manifestations will facilitate timely diagnosis and management, which is paramount to further improving outcomes for patients with cystic fibrosis.

  10. Methods of patient warming during abdominal surgery.

    Directory of Open Access Journals (Sweden)

    Li Shao

    Full Text Available BACKGROUND: Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. METHODS: Patients (n = 160 scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients' nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. RESULTS: When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. DISCUSSION: The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed.

    Full Text Available Abstract Background To summarize the diagnostic and therapeutic experiences on the patients who suffered abdominal complications after cardiovascular surgery with cardiopulmonary bypass(CPB. Methods A total of 2349 consecutive patients submitted to cardiovascular surgery with CPB in our hospital from Jan 2004 to Dec 2010 were involved. The clinical data of any abdominal complication, including its incidence, characters, relative risks, diagnostic measures, medical or surgical management and mortality, was retrospectively analyzed. Results Of all the patients, 33(1.4% developed abdominal complications postoperatively, including 11(33.3% cases of paralytic ileus, 9(27.3% of gastrointestinal haemorrhage, 2(6.1% of gastroduodenal ulcer perforation, 2(6.1% of acute calculus cholecystitis, 3(9.1% of acute acalculus cholecystitis, 4(12.1% of hepatic dysfunction and 2(6.1% of ischemia bowel diseases. Of the 33 patients, 26 (78.8% accepted medical treatment and 7 (21.2% underwent subsequent surgical intervention. There were 5(15.2% deaths in this series, which was significantly higher than the overall mortality (2.7%. Positive history of peptic ulcer, advanced ages, bad heart function, preoperative IABP support, prolonged CPB time, low cardiac output and prolonged mechanical ventilation are the risk factors of abdominal complications. Conclusions Abdominal complications after cardiovascular surgery with CPB have a low incidence but a higher mortality. Early detection and prompt appropriate intervention are essential for the outcome of the patients.

    Full Text Available Gossypiboma is a mass lesion at the site of surgery due to a forgotten surgical sponge. Forgotten foreign bodies are mostly retained in the abdominal cavity but there are some cases in the thorax, cranium, breast, and an extremity. Gossypiboma should be considered, especially by radiologists, in patients with a history of surgery, who present with non-specific symptoms and abdominal mass. In this report, we describe the case of a female patient who presented with non-specific abdominal discomfort and fever about six months after open cholecystectomy.

    Fernando Antonio C. Spencer Netto

    Full Text Available Abdominal aorta wounds carries a high immediate mortality. Few patients reach hospital care alive. There are no reports on Medline (1969-2002 about aortic wounds of foreign body with retention. A case with upper abdominal aortic wound with an inlaid blade is reported. The retained blade fixed the stomach to the surgical field, difficulting the vascular control, leading to an unconventional approach and allowing extensive contamination. The patient developed multiple organ dysfunction and died at fifth postoperative day. Singularities of an inlaid knife in upper abdominal aorta and changes in traditional approach are discussed. The authors assumed that the inlaid knife decreased the bleeding, allowing the patient arrival to the hospital, but worsened the approach to the aorta wound.

    Full Text Available Coarctation of the abdominal aorta is an extremely rare vascular defect inwhich congenital or acquired etiologies have been described. This case concernsa 30-year-old pregnant woman with 15-years history of uncontrolled hypertensionand lower limb claudication presented with worsened hypertension during herfirst pregnancy. Magnetic resonance angiography study of aorta revealed astenosis in abdominal aorta about 12mm from the origin of celiac axisaccompanied by left sided aortic arch and right aberrant subclavian artery. Thiscase highlights the importance of a throughout physical examination in patientspresented with hypertension and it emphasizes considering the coarctation of theabdominal aorta during the diagnostic workup of hypertension, especially inyoung patients. In such cases magnetic resonance angiography of the aorta is auseful tool to reach a definitive diagnosis especially in pregnant women.Also to our knowledge, this patient is the first one found to have aortic archmalformation combined with an abdominal coarctation.

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

  18. Effects of collagen matrix and bioreactor cultivation on cartilage regeneration of a full-thickness critical-size knee joint cartilage defects with subchondral bone damage in a rabbit model.

    Full Text Available Cartilage has limited self-repair ability. The purpose of this study was to investigate the effects of different species of collagen-engineered neocartilage for the treatment of critical-size defects in the articular joint in a rabbit model. Type II and I collagen obtained from rabbits and rats was mixed to form a scaffold. The type II/I collagen scaffold was then mixed with rabbit chondrocytes to biofabricate neocartilage constructs using a rotating cell culture system [three-dimensional (3D-bioreactor]. The rabbit chondrocytes were mixed with rabbit collagen scaffold and rat collagen scaffold to form neoRBT (neo-rabbit cartilage and neoRAT (neo-rat cartilage constructs, respectively. The neocartilage matrix constructs were implanted into surgically created defects in rabbit knee chondyles, and histological examinations were performed after 2 and 3 months. Cartilage-like lacunae formation surrounding the chondrocytes was noted in the cell cultures. After 3 months, both the neoRBT and neoRAT groups showed cartilage-like repair tissue covering the 5-mm circular, 4-mm-deep defects that were created in the rabbit condyle and filled with neocartilage plugs. Reparative chondrocytes were aligned as apparent clusters in both the neoRAT and neoRBT groups. Both neoRBT and neoRAT cartilage repair demonstrated integration with healthy adjacent tissue; however, more integration was obtained using the neoRAT cartilage. Our data indicate that different species of type II/I collagen matrix and 3D bioreactor cultivation can facilitate cartilage engineering in vitro for the repair of critical-size defect.

    Full Text Available Abdominoplasty is among the most commonly performed aesthetic procedures in plastic surgery. Despite high complication rate, abdominal contouring procedures are expected to rise in popularity with the advent of bariatric surgery. Patients with a history of gastric bypass surgery have an elevated incidence of small bowel obstruction from internal herniation, which is associated with non-specific upper abdominal pain, nausea, and a decrease in appetite. Internal hernias, when subjected to elevated intra-abdominal pressures, have a high-risk of developing ischemic bowel. We present a case report of patient with previous laparoscopic Roux-en-y gastric bypass who developed acute ischemic bowel leading to abdominal compartment syndrome following abdominoplasty. To the best of our knowledge, this is the first reported case in the literature. We herein emphasise on the subtle symptoms and signs that warrant further investigations in prospective patients for an abdominal contouring procedure with a prior history of gastric bypass surgery.

    Full Text Available Penetrating abdominal trauma has been traditionally treated by exploratory laparotomy. Nowadays laparoscopy has become an accepted practice in hemodynamically stable patient without signs of peritonitis. We report a case of a lower anterior abdominal gunshot patient treated laparoscopically. A 32-year-old male presented to the Emergency Department with complaint of gunshot penetrating injury at left lower anterior abdominal wall. The patient had no symptoms or obvious bleeding and was vitally stable. On examination we identified 1 cm diameter entry wound at the left lower abdominal wall. The imaging studies showed the bullet in the peritoneal cavity but no injured intraperitoneal and retroperitoneal viscera. We decided to remove the bullet laparoscopically. Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically.

  2. [Differential diagnosis of abdominal pain].

    Science.gov (United States)

    Frei, Pascal

    2015-09-02

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain.

    2004-01-01

    A 32-year-old Filipino female, working as an x-ray technician, presented to the Emergency Room (ER) with acute abdominal pain for one day. The pain was mainly on the left side and left hypochondrium. She had recurring abdominal pain before but not significant to worry her. She also complained of abdominal distension, which she noticed one week ago. Abdominal examination revealed fullness in the left hypochondrium with marked tenderness but negative rebound. Abdominal ultrasound (US) showed a huge mass mainly in the left hypochondrium. The origin of the mass cannot be identified by US. A computerized tomography scan showed a mass in the left side of the abdomen crossing the midline with a necrotic centre. The hospital course of the patient runs smoothly, and she was discharged after 7-days and referred to an Oncology Center. Abdominal mesothelioma is a neoplasm arising from the mesothelial surface lining the abdominal cavity. It is less frequent than that of the pleura. It is a rapidly growing and fatal malignancy with a median survival of less than 1-year. The relation between pleural malignant mesothelioma and asbestos is well recognized since it was described in 19602 but implication of asbestos exposure in the etiology of the peritoneal type is less obvious. This patient history is giving no obvious exposure to asbestos but as she is working in the Radiology Department as an x-ray technician she is well exposed to x-ray, but the effect of radioactivity on induction of mesothelioma is still disputed.4 There are several reports linking malignant mesothelioma to radioactivity due to radiation therapy.The fibrous mesothelioma (sarcomatous), as in this case, which is difficult to diagnose microscopically, looks like a fibroma, unless helped by tissue culture. The treatment options of malignant mesothelioma include surgery, intraperitoneal chemotherapy and whole abdominal radiation or multimodality therapy, which were suggested that might prolong the survival in

    This article discusses abdominal aortic emergencies. There is a common thread of risk factors and causes of these diseases, including age, male gender, hypertension, dyslipidemia, and connective tissue disorders. The most common presenting symptom of these disorders is pain, usually in the chest, flank, abdomen, or back. Computed tomography scan is the gold standard for diagnosis of pathologic conditions of the aorta in the hemodynamically stable patient. Treatment consists of a combination of blood pressure and heart rate control and, in many cases, emergent surgical intervention. Copyright © 2017 Elsevier Inc. All rights reserved.

    The abdominal wall is often neglected as a cause of chronic abdominal pain. The aim of this study was to identify chronic abdominal wall pain syndromes, such as anterior cutaneous nerve entrapment syndrome (ACNES), in a patient population diagnosed with functional abdominal pain, including irritable bowel syndrome, using a validated 18-item questionnaire as an identification tool. In this cross-sectional analysis, 4 Dutch primary care practices employing physicians who were unaware of the existence of ACNES were selected. A total of 535 patients ≥18 years old who were registered with a functional abdominal pain diagnosis were approached when they were symptomatic to complete the questionnaire (maximum 18 points). Responders who scored at least the 10-point cutoff value (sensitivity, 0.94; specificity, 0.92) underwent a diagnostic evaluation to establish their final diagnosis. The main outcome was the presence and prevalence of ACNES in a group of symptomatic patients diagnosed with functional abdominal pain. Of 535 patients, 304 (57%) responded; 167 subjects (31%) recently reporting symptoms completed the questionnaire. Of 23 patients who scored above the 10-point cutoff value, 18 were available for a diagnostic evaluation. In half of these subjects (n = 9) functional abdominal pain (including IBS) was confirmed. However, the other 9 patients were suffering from abdominal wall pain syndrome, 6 of whom were diagnosed with ACNES (3.6% prevalence rate of symptomatic subjects; 95% confidence interval, 1.7-7.6), whereas the remaining 3 harbored a painful lipoma, an abdominal herniation, and a painful scar. A clinically relevant portion of patients previously diagnosed with functional abdominal pain syndrome in a primary care environment suffers from an abdominal wall pain syndrome such as ACNES.

    Full Text Available Publications of recent years do not reflect the regional dynamics of hospitalization of patients with acute surgical pathology of the abdominal cavity and anterior abdominal wall. Goal – to determine the volume of hospitalizations and treatment of patients with acute surgical pathology of the abdominal and anterior abdominal wall in the Kuzbass in the dynamics from 1993 to 2016. Materials and methods. A comparative analysis of the volume of treatment of patients with acute appendicitis, acute cholecystitis, acute pancreatitis, intestinal obstruction, perforated ulcer of the stomach and duodenum and strangulated hernia in surgical departments of Kuzbass from 1993 to 2016 to understand the changes occurring in abdominal surgery. Estimated in the comparative aspect for two decades (1993-2002 and 2007-2016 the average annual number of treated. The estimation of indicators in calculation on 100000 population is executed. The statistical processing was carried out using IBM SPSS Statistica computer version 24 and the nonparametric Mann-Whitney test. Result. Statistically significantly decreased the number of patients with acute appendicitis and perforated ulcers of the stomach and duodenum. The average annual hospitalization of patients with acute pancreatitis and strangulated abdominal hernias has significantly increased in the last decade. There are no significant differences in the increase in the total number of patients with acute cholecystitis and acute intestinal obstruction. Conclusions: 1. Over the past decade compared with 1993-2002, the incidence of acute appendicitis per 100000 thousand of the population decreased in the region by 39.9 %, the incidence of perforated gastric ulcer and duodenal ulcer by 30.2 %. 2. At this time, the number of people treated with 100000 people with acute pancreatitis increased by 94.7 %; with acute cholecystitis by 12.4 %; with an acute intestinal obstruction by 9.8 % and with a strangulated

    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

    Full Text Available Abdominal compartment syndrome (ACS is defined as an elevated intraabdominal pressure with evidence of organ dysfunction. The majority of published reports of ACS are in neonates with abdominal wall defects and in adults following trauma or burns, but it is poorly described in children. We describe the unusual presentation of an 11-year-old boy with a long history of chronic constipation who developed acute ACS requiring resuscitative measures and emergent disimpaction. He presented with a 2-week history of increasing abdominal pain, nausea, diminished appetite and longstanding encopresis. On exam, he was emaciated with a massively distended abdomen with a palpable fecaloma. Abdominal XR confirmed these findings. Within 24 hours of presentation, he became tachycardic and oliguric with orthostatic hypotension. Following two enemas, he acutely deteriorated with severe hypotension, marked tachycardia, acute respiratory distress, and a declining mental status. Endotracheal intubation, fluid boluses, and vasopressors were commenced, followed by emergent surgical fecal disimpaction. This resulted in rapid improvement in vital signs. He has been thoroughly investigated and no other condition apart from functional constipation has been identified. Although ACS secondary to constipation is extremely unusual, this case illustrates the need to actively treat constipation and what can happen if it is not.

    Full Text Available Epiploic appendagitis (EA is an uncommon cause of abdominal pain. It is a benign condition but may mimic other serious causes of acute abdomen such as appendicitis, diverticulitis, and gynecological emergency in severe cases. Knowledge of this condition in the differential diagnosis of abdominal pain can save unnecessary hospital admission, antibiotics, and surgery. In this article, we present the case of a 43-year-old female who presented to our hospital with a 2-day history of right lower quadrant abdominal pain and diarrhea. She was diagnosed with EA with computed tomography of abdomen with contrast and was managed conservatively with good outcome.

    Abdominal ultrasonography was performed in six adult captive caracals (Caracal caracal) to describe the normal abdominal ultrasonographic anatomy. Consistently, the splenic parenchyma was hyperechoic to the liver and kidneys. The relative echogenicity of the right kidney's cortex was inconsistent to the liver. The gall bladder was prominent in five animals and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The wall thickness of the duodenum measured significantly greater compared with that of the jejunum and colon. The duodenum had a significantly thicker mucosal layer compared with that of the stomach. Such knowledge of the normal abdominal ultrasonographic anatomy of individual species is important for accurate diagnosis and interpretation of routine health examinations.

    Although the number of elective operations for abdominal aortic aneurysms (AAA) is increasing, the sex- and age-standardised mortality rate of AAAs continues to rise, especially among men aged 65 years or more. The lethality of ruptured AAA continues to be 80-95%, compared with 5-7% by elective...... surgery of symptomfree AAA. In order to fulfil all WHO, European, and Danish criteria for screening, a randomised hospitalbased screening trial of 12,639 65-73 year old men in Viborg County (Denmark) was initiated in 1994. It seemed that US screening is a valid, suitable and acceptable method of screening...... patients without previous hospital discharge diagnoses due to cardiovascular disease than among similar men without AAA. The absolute risk difference after 5 years was 16%. So, they will benefit from general cardiovascular preventive action as smoking cessation, statins and low-dose aspirin, which could...

    Purpose: As scarce information is available, in this research we have tried to describe the imaging findings of the Burkitt's lymphoma. Retrospective analysis of the clinical and imaging presentation of a 4 years old boy, is given. Biopsy confirmed the BL. Different imaging techniques were combined. The X-rays were negative. The US revealed a moderate hepatomegaly with multiple hypoechoic nodules and free fluid in the abdominal cavity. The CT showed the hepatomegaly as well as solid nodules in great number and different sizes(due to the densitometric behaviour and to post contrast enhancement), a scarce amount of ascites and a density increase of the mesentery fat. The MRI characterized and revealed in detail the US and the CT findings. The Burkitt's lymphoma is a rare entity; several methods are needed to approach the diagnosis. It represents a great clinical and imaging challenge. (author)

    Functional abdominal pain syndrome (FAPS) differs from the other functional bowel disorders; it is less common, symptoms largely are unrelated to food intake and defecation, and it has higher comorbidity with psychiatric disorders. The etiology and pathophysiology are incompletely understood. Because FAPS likely represents a heterogeneous group of disorders, peripheral neuropathic pain mechanisms, alterations in endogenous pain modulation systems, or both may be involved in any one patient. The diagnosis of FAPS is made on the basis of positive symptom criteria and a longstanding history of symptoms; in the absence of alarm symptoms, an extensive diagnostic evaluation is not required. Management is based on a therapeutic physician-patient relationship and empirical treatment algorithms using various classes of centrally acting drugs, including antidepressants and anticonvulsants. The choice, dose, and combination of drugs are influenced by psychiatric comorbidities. Psychological treatment options include psychotherapy, relaxation techniques, and hypnosis. Refractory FAPS patients may benefit from a multidisciplinary pain clinic approach.

    Full Text Available Objective: to substantiate the choice of a gastrointestinal tract (GIT function support regimen as a mode for correction of the abdominal compartment syndrome (ACS. Subjects and methods. Forty-three patients with different causes of inadequate GIT function of various origin and ACS (disseminated peritonitis (45%, pancreatitis (24%, and severe concomitant injury (31% were examined. Group 1 (control received complete parenteral nutritional feeding (n=23; APACHE II scores, 21±4; calculated probability of fatal outcome, 33.5%. In Group II (study, complete parenteral feeding in the first 24 hours after stabilization was supplemented with GIT function support with Pepsisorb (Nutricia in doses of 500, 1000, and 1500 ml on days 1, 2, and 3, respectively (n=20; APACHE II scores, 20±6; calculated probability of fatal outcome, 37.1%. During early enteral nutritional support, the SOFA score was significantly less than that in Group 1 on days 2—3; the oxygenation index significantly increased on day 3; the value of intra-abdominal hypertension decreased to the control values. The positive effect of the GIT function support regimen on regression of the multiple organ dysfunction syndrome (MODS was confirmed by the lowered levels of biological markers (von Willebrand factor (WF and endothelin-1 as markers of endothelial damage of MODS. Correlation analysis showed a direct correlation between the markers of endothelial damage and the SOFA scores (r=0.34; p=0.05 for WF and r=0.49;p=0.03 for endothelin. Conclusion. The GIT function support regimen via early enteral alimentation with Peptisorb, which was initiated in the first 24 hours after admission, is able to level off the manifestations of the early stages of the abdominal compartment syndrome, with the acceptable values of oxygen balance and water-electrolyte and osmotic homeostasis being achieved.

    Full Text Available Abstract Introduction Abdominal organ injury in a primary blast type is always challenging for diagnosis. Air containing abdominal viscera is most vulnerable to effects of primary blast injury. In any patient exposed to a primary blast wave who presents with an acute abdomen, an abdominal organ injury is to be kept in a clinical suspicion. Aim Study various abdominal organ injuries occurring in a primary type of blast injury. Material and methods: All those who had exploratory laparotomy for abdominal organ injuries after a primary blast injury for a period of 10 years from January 1998 - January 2008 were included in this retrospective study. Results Total 154 patients had laparotomy for abdominal organ injuries with a primary blast type of injury. Small intestine was damaged in 48 patients (31.1% followed by spleen in 22.7% cases. 54 patients (35.06% had more than one organ injured. Liver laceration was present in 30 patients (19.48%. Multiple small gut perforations were present in 37 patients (77.08%. Negative laparotomy was found in 5 patients (3.24% whereas 3 (1.94% had re-exploration. Mortality was present in 6 patients (3.89%. Conclusions Primary blast injury causes varied abdominal organ injuries. Single or multiple organ damage can be there. Small intestine is commonest viscera injured. Laparotomy gives final diagnosis.

    Full Text Available Background: Waist circumference perimeter, as an indirect indicator of abdominal obesity, is commonly presented as an essential element in the clinical assessment of obesity. The link between abdominal obesity and insulin resistance is proposed as the core of metabolic syndrome’s pathophysiology and complications. Objective: To determine whether individuals with abdominal obesity present characteristics related to metabolic syndrome’s factors that differ from those observed in individuals with no abdominal obesity. Methods: A comparative analytical study was performed including cases control and design in two different groups. The sample was composed of 98 individuals of both sexes randomly selected out of a universe of 510 workers population at the Medical University of Cienfuegos from September to December 2005. They were all tested as to blood pressure, cholesterol, HDL cholesterol, fasting glucose and triglycerides. Results: Abdominal obesity was found in 30.6% of individuals. It was predominant in females (83.3% older than 40 years. The number of cases of obesity linked to hypertension was similar to the number of cases with low HDL cholesterol (53.3%. Impaired glucose was found in 16.7% of cases. Conclusions: Abdominal obesity is a health problem in the population included in this study and it increases as age does. Individuals with abdominal obesity are exposed to a higher risk of metabolic disorders, such as low levels of HDL cholesterol, high levels of triglycerides and total cholesterol, glucose alterations and hypertension.

    2004-01-01

    Elephantiasis is a well-known condition in dermatology usually affecting the legs and external genitalia. It is characterized by chronic inflammation and obstruction of the lymphatic channels and by hypertrophy of the skin and subcutaneous tissues. The etiology is either idiopathic or caused by a variety of conditions such as chronic filarial disease, leprosy, leishmaniasis, and chronic recurrent cellulites. Elephantiasis of the abdominal wall is very rare. A complete review of the English and French literature showed only two cases reported in 1966 and 1973, respectively. We report a third case of abdominal elephantiasis and we briefly review this entity. We present the case of a 51-year-old woman who had progressively developed an enormous pediculated abdominal mass hanging down her knees. The skin was thickened, hyperpigmented, and fissured. She had a history of multiple abdominal cellulites. She underwent an abdominal lipectomy. Histopathology of the specimen confirmed the diagnosis of abdominal elephantiasis. Abdominal elephantiasis is a rare disease that represents end-stage failure of lymph drainage. Lipectomy should be considered in the management of this condition.

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

  9. Economics of abdominal wall reconstruction.

    2013-10-01

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    A previously healthy 3-week-old boy presented with 5 hours of marked fussiness, abdominal distention, and poor feeding. He was afebrile and well perfused. His examination was remarkable for localized abdominal tenderness and distention. He was referred to the emergency department in which an abdominal radiograph revealed gaseous distention of the bowel with a paucity of gas in the pelvis. Complete blood cell count and urinalysis were unremarkable. His ongoing fussiness and abnormal physical examination prompted consultation with surgery and radiology. Our combined efforts ultimately established an unexpected diagnosis. Copyright © 2017 by the American Academy of Pediatrics.

  11. Radioactive thickness gauge (1962)

    Guizerix, J.

    1962-01-01

    The author describes a thickness gauge in which the scintillating crystal detector alternately 'sees' a radioactive source through the material which is to be measured and then a control source of the same material; the radiations are separated in time by an absorbing valve whose sections are alternately full and hollow. The currents corresponding to the two sources are separated beyond the photomultiplier tube by a detector synchronized with the rotation of the valve. The quotient of these two currents is then obtained with a standard recording potentiometer. It is found that the average value of the response which is in the form G = f(I 1 /I 2 ) is not affected by decay of the radioactive sources, and that it is little influenced by variations of high tension, temperature, or properties of the air in the source detector interval. The performance of the gauge is given. (author) [fr

    Full Text Available Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7% males and 20 (18.3% females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years. The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%, colon 48 (44%, and liver 41 (37.6%. Forty-four (40.4% patients had extra-abdominal injuries involving the chest in 17 (15.6%, musculoskeletal 12 (11%, and the head in 9 (8.3%. The most prevalent weapon injuries were gunshot 76 (69.7%, explosives 12 (11%, stab injuries 11 (10.1%, and blunt abdominal trauma 10 (9.2%. The injury severity score varied from 8 to 52 (mean: 20.8 with a fatality rate of 11 (10.1% and morbidity rate of 29 (26.6%. Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems.

    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer. 2014 BMJ Publishing Group Ltd.

  14. Contralateral Abdominal Pocketing in Salvation of Replanted Fingertips with Compromised Circulation

    2014-01-01

    Full Text Available Abdominal pocketing is one of the most useful methods in salvation of compromised replanted fingertips. Abdominal pocketing has generally been performed in the ipsilateral lower abdominal quadrant, but we have also performed contralateral pocketing at our institute. To determine which approach is more beneficial, a total of 40 patients underwent an abdominal pocketing procedure in either the ipsilateral or contralateral lower abdominal quadrant after fingertip replantation. Dates of abdominal pocketing after initial replantation, detachment after abdominal pocketing, range of motion (ROM before abdominal pocketing, and sequential ROM after the detachment operation and date of full ROM recovery and Disabilities of Arm, Shoulder, and Hand questionnaire (DASH score were recorded through medical chart review. Mean detachment date, mean abduction of shoulder after the detachment operation, and mean days to return to full ROM were not significantly different between the ipsilateral and contralateral pocketing groups. However, the mean DASH score was significantly lower in the contralateral group than the ipsilateral group. There were also fewer postoperative wound complications in the contralateral group than in the ipsilateral group. We, therefore, recommend contralateral abdominal pocketing rather than ipsilateral abdominal pocketing to increase patient comfort and reduce pain and complications.

  15. A clinically relevant in vivo model for the assessment of scaffold efficacy in abdominal wall reconstruction

    Directory of Open Access Journals (Sweden)

    Jeffrey CY Chan

    2016-12-01

    Full Text Available An animal model that allows for assessment of the degree of stretching or contraction of the implant area and the in vivo degradation properties of biological meshes is required to evaluate their performance in vivo. Adult New Zealand rabbits underwent full thickness subtotal unilateral rectus abdominis muscle excision and were reconstructed with the non-biodegradable Peri-Guard®, Prolene® or biodegradable Surgisis® meshes. Following 8 weeks of recovery, the anterior abdominal wall tissue samples were collected for measurement of the implant dimensions. The Peri-Guard and Prolene meshes showed a slight and obvious shrinkage, respectively, whereas the Surgisis mesh showed stretching, resulting in hernia formation. Surgisis meshes showed in vivo biodegradation and increased collagen formation. This surgical rabbit model for abdominal wall defects is advantageous for evaluating the in vivo behaviour of surgical meshes. Implant area stretching and shrinkage were detected corresponding to mesh properties, and histological analysis and stereological methods supported these findings.

  16. A Rare Cause of Abdominal Pain in Childhood: Cardiac Angiosarcoma

    Directory of Open Access Journals (Sweden)

    Elvan Caglar Citak

    Full Text Available Abstract Cardiac angiosarcomas are extremely rare in childhood, they are rapidly progressive tumours that often present themselves as diagnostic dilemmas, resulting in delayed diagnosis. Also, extracardiac manifestations, including abdominal pain, are extremely rare in patients with intracardiac tumors. We herein present the case of a 15-year-old girl who presented with abdominal pain. Echocardiography and thoracic computed tomography showed right atrial mass. The patient underwent surgery, chemotherapy, and radiotherapy. Eight months after treatment, abdominal recurrence was detected. The abdominal mass was resected, and radiotherapy and new chemotherapy protocol were given. The present case illustrates a rare case of primary cardiac angiosarcoma posing a diagnostic dilemma in an adolescent girl.

    Full Text Available A 37-year-old female patient with chronic and stubborn abdominal pain had been hospitalized five times in three Western hospitals, but no effects were observed. No abnormalities were found in blood tests, gastrointestinal endoscopy, sonogram, and computed tomography of the abdomen, except mild paralytic ileus. The patient decided to rely on Korean medicine as an inpatient. She was diagnosed with functional abdominal pain syndrome, and her symptom differentiation was the “Yang deficiency of spleen and kidney.” A herbal drug, Hwangikyeji-tang, along with moxibustion and acupuncture, was given to the patient. Abdominal pain and related symptoms were reduced radically within 16 days of treatment. This report shows a therapeutic potential of Korean medicine-based treatment for functional abdominal pain syndrome.

    Full Text Available A rare case of ascaris coming out through the anterior abdominal wall is reported here. A 40-year-old female had undergone dilatation and curettage by a quack. On the second day she presented with presented with features of peritonitis. She was explored. Resection anastomosis of the ileum was done for multiple perforations of the ileum. Patient developed a fistula in the anterior abdominal wall which was draining bile-colored fluid. On the 12 th postoperative day a 10-cm-long worm was seen coming out through the fistulous tract which was found to be Ascaris lumbricoids. Ascaris lumbricoids can lead to many complications ranging from worm colic to intestinal obstruction, volvulus, peritonitis, pancreatitis, cholangiohepatitis, liver abscess and many more. Worm has been reported to come out through mouth, nostrils, abdominal drains, T-tubes etc. But ascaris coming out through the anterior abdominal wall is very rare hence reported here.

    We report the case of a 15-year-old boy suffering from progressive dyspnea on exertion and painful abdominal protrusion. Final diagnosis of intra-abdominal tuberculosis (TB), including lymphadenopathy and abdominal abscess formation, was made following elective laparotomy. This type of disease is a rare manifestation of extrapulmonary tuberculosis. The imaging findings in unenhanced and contrast-enhanced MRI and laparoscopic images are presented. Differential diagnosis of abdominal abscess formation and other fungal or bacteriological infections, as well as the imaging findings of this type of lesion, are discussed. This case demonstrates that atypical manifestation of TB may remain unrecognized; thus, awareness of this kind of manifestation of tuberculosis may prevent patients from being subjected to inappropriate therapies.

    Incisional hernia is a common long-term complication to abdominal surgery, occurring in more than 20% of all patients. Some of these hernias become giant and affect patients in several ways. This patient group often experiences pain, decreased perceived body image, and loss of physical function......, which results in a need for surgical repair of the giant hernia, known as abdominal wall reconstruction. In the current thesis, patients with a giant hernia were examined to achieve a better understanding of their physical and psychological function before and after abdominal wall reconstruction. Study...... was lacking. Study II was a case-control study of the effects of an enhanced recovery after surgery pathway for patients undergoing abdominal wall reconstruction for a giant hernia.

    Abdominal actinomycosis is a chronic, progressive, suppurative disease with a favorable response to intravenous treatment with penicillin. In many instances, however, its clinical and radiological findings may overlap with those of other inflammatory and neoplastic conditions, and the familiarity with the various radiological features can thus avoid diagnostic delays. The purpose of this paper is to describe and discuss the CT findings of abdominal actinomycosis

  5. Blunt abdominal trauma in children.

    2012-06-01

    This review will examine the current evidence regarding pediatric blunt abdominal trauma and the physical exam findings, laboratory values, and radiographic imaging associated with the diagnosis of intra-abdominal injuries (IAI), as well as review the current literature on pediatric hollow viscus injuries and emergency department disposition after diagnosis. The importance of the seat belt sign on physical examination and screening laboratory data remains controversial, although screening hepatic enzymes are recommended in the evaluation of nonaccidental trauma to identify occult abdominal organ injuries. Focused Assessment with Sonography for Trauma (FAST) has modest sensitivity for hemoperitoneum and IAI in the pediatric trauma patient. Patients with concern for undiagnosed IAI, including bowel injury, may be considered for hospital admission and serial abdominal exams without an increased risk of complications, if an exploratory laparotomy is not performed emergently. Although the FAST exam is not recommended as the sole screening tool to rule out IAI in hemodynamically stable trauma patients, it may be used in conjunction with the physical exam and laboratory findings to identify children at risk for IAI. Children with a normal physical exam and normal abdominal CT may not require routine hospitalization after blunt abdominal trauma.

    Full Text Available Abstract: Annually hundreds of crab-eating foxes (Cerdocyon thous are referred to rehabilitation centers and zoos in Brazil. The ultrasonographic study of wildlife species is an important tool for a non-invasive and accurate anatomical description and provides important information for wildlife veterinary care. The aim of the present study was to determine the characteristics of the main abdominal organs as well as the vascular indexes of the abdominal aorta and renal arteries of crab-eating foxes (Cerdocyon thous using mode B ultrasonography and Doppler ultrasonography, respectively. Ultrasonographic features of the main abdominal organs were described and slight differences were noticed between ultrasound imaging of abdominal organs of crab-eating foxes and other species. The bladder presented wall thickness of 12±0.01mm, with three defined layers. Both, the right and left kidneys presented corticomedullary ratio of 1:1 and similarly to the adrenals and the liver, they were homogeneous and hypoechoic compared to the spleen. The spleen was homogeneous and hyperechoic compared to the kidneys. The stomach presented 3 to 5 peristaltic movements per minute, wall thickness of 39±0.05mm and lumen and mucosa with hyperechoic and hypoechoic features, respectively. Small and large intestines presented 2 to 3 peristaltic movements per minute, wall thickness of 34±0.03mm and three defined layers with hyperechogenic (submucosa and serosa and hypoechogenic (muscular features. Ovaries of the female crab-eating fox were hypoechoic compared to the spleen and with heterogeneous parenchyma due to the presence of 2x2mm ovarian follicles. Prostates of the six males were regular and with a well defined boundary, with a homogeneous and hyperechoic parenchyma compared to the spleen. Vascular indexes of the abdominal aorta (PSV: 25.60±0.32cm/s; EDV: 6.96±1.68cm/s; PI: 1.15±0.07 e RI: 0.73±0.07 and right (PSV: 23.08±3.34cm/s; EDV: 9.33±2.36cm/s; PI: 1.01±0

    To investigate the association between the size of the hepatic hemangioma and the shape and thickness of the echogenic rim of hepatic hemangioma on abdominal ultrasound. We examined 47 cases (M:F=24:23, mean age 47.1) of hepatic hemangiomas with echogenic rim on abdominal ultrasound during the past 2 years. Radiologic findings were retrospectively reviewed in terms of completeness and thickness of echogenic rim. If echogenic rim showed even thickness, it was measured. But if not, the maximum and minimum thickness of the rim was measured. The association between the size of hemangioma and the completeness and thickness of the echogenic rim were analyzed statistically. Of the 47 cases, complete echogenic rim and incomplete echogenic rim were obtained in 29 (62%) and 18 (38%) cases, respectively. Twenty-two cases of hemangioma were less than 2 cm in diameter, and their distribution according to echogenic rim were as follows: complete echogenic rim (17/20, 91% mean thickness 2.2 cm) and uneven thickness with complete echogenic rim (3/20, 15%, range:2.0-6.1 mm). Twenty-five hemangiomas were larger than 2 cm in diameter and their distribution according to echogenic rim were as follows: complete echogenic rim (n=9, 34%), incomplete echogenic rim (n=16, 64%0,even thickness with complete echogenic rim (3/9, 33%, mean thickness 2.2 mm) and uneven thickness with complete echogenic rim (6/9,67%, range: 2.0-7.6 mm). In statistical analysis, hemangiomas more than 2 cm in diameter were more likely to have incomplete echogenic rim (p<0.05) than those of less than 2 cm; hemangiomas more than with more than 2 cm in diameter and complete echogenic rim showed uneven thickness of echogenic rim (p<0.05), more often than those of less than 2 cm diameter. Hemangiomas with more than 2 cm in diameter showed more frequent incomplete echogenic rim than those of less than 2 cm in diameter, which had more frequent complete echogenic rim. Hemangiomas with complete echogenic rim and even rim

    Full Text Available Excess visceral fat is associated with cardiovascular risk factors. Sagittal abdominal diameter (SAD has recently been highlighted as an indicator of abdominal obesity, and also may be useful in predicting cardiovascular risk. The purpose of the present study was to review the scientific literature on the use of SAD in adult nutritional assessment. A search was conducted for scientific articles in the following electronic databases: SciELO , MEDLINE (PubMed and Virtual Health Library. SAD is more associated with abdominal fat (especially visceral, and with different cardiovascular risk factors, such as, insulin resistance, blood pressure, and serum lipoproteins than the traditional methods of estimating adiposity, such as body mass index and waist-to-hip ratio. SAD can also be used in association with other anthropometric measures. There are still no cut-off limits established to classify SAD as yet. SAD can be an alternative measure to estimate visceral adiposity. However, the few studies on this diameter, and the lack of consensus on the anatomical site to measure SAD, are obstacles to establish cut-off limits to classify it.

    Morel-Lavallee lesions (MLLs) are rare internal degloving injuries typically caused by blunt traumatic injuries and most commonly occur around the hips and in association with pelvic or acetabular fractures. MLL is often overlooked in the setting of poly-trauma; therefore, clinicians must maintain a high degree of suspicion and be familiar with the management of such injuries, especially in obese poly-trauma patients. We present a 30-year-old female pedestrian struck by a motor vehicle who sustained multiple long bone fractures, a mesenteric hematoma, and full-thickness abdominal skin friction burn which masked a significant underlying abdominal MLL. The internal degloving caused significant devascularization of the overlying soft tissue and skin which required surgical drainage of hematoma, abdominal wall reconstruction with tangential excision, allografting, negative pressure wound therapy, and ultimately autografting. MLL is a rare, often overlooked, internal degloving injury. Surgeons must maintain a high index of suspicion when dealing with third degree friction burns as they may mask underlying injuries such as MLL, and a delay in diagnosis can lead to increased morbidity.

    Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder of unknown etiology. Although relatively common in children, how this condition affects brain structure and function in a pediatric population remains unclear. Here, we investigate brain changes in adolescents with IBS and healthy controls. Imaging was performed with a Siemens 3 Tesla Trio Tim MRI scanner equipped with a 32-channel head coil. A high-resolution T1-weighted anatomical scan was acquired followed by a T2-weighted functional scan. We used a surface-based morphometric approach along with a seed-based resting-state functional connectivity (RS-FC) analysis to determine if groups differed in cortical thickness and whether areas showing structural differences also showed abnormal RS-FC patterns. Patients completed the Abdominal Pain Index and the GI Module of the Pediatric Quality of Life Inventory to assess abdominal pain severity and impact of GI symptoms on health-related quality of life (HRQOL). Disease duration and pain intensity were also assessed. Pediatric IBS patients, relative to controls, showed cortical thickening in the posterior cingulate (PCC), whereas cortical thinning in posterior parietal and prefrontal areas were found, including the dorsolateral prefrontal cortex (DLPFC). In patients, abdominal pain severity was related to cortical thickening in the intra-abdominal area of the primary somatosensory cortex (SI), whereas HRQOL was associated with insular cortical thinning. Disease severity measures correlated with cortical thickness in bilateral DLPFC and orbitofrontal cortex. Patients also showed reduced anti-correlations between PCC and DLPFC compared to controls, a finding that may reflect aberrant connectivity between default mode and cognitive control networks. We are the first to demonstrate concomitant structural and functional brain changes associated with abdominal pain severity, HRQOL related to GI-specific symptoms, and disease-specific measures in

    Abdominal hernias are a common clinical problem Clinical diagnosis of abdominal hernias can sometimes be challenging, particularly in obese patients or patients with previous abdominal surgery. CT scan of the abdomen allows visualization of hernias and their contents and the differentiation from other masses of the abdominal wall such as tumors, hematomas and abscesses. Moreover, CT may identify complications such as incarceration, bowel obstruction, volvulus and strangulation. This study illustrates the CT scan findings observed in different types of abdominal wall hernias. (author)

    Delayed foot wound healing is a major complication attributed to hyperglycemia in type 2 diabetes mellitus (DM) patients, and these wounds may develop into foot ulcers. There are at least two types of DM wound models used in rodents to study delayed wound healing. However, clinically relevant animal models are not common. Most models use type 1 DM rodents or wounds created on the back rather than on the foot. An open full-thickness excision wound on the footpad of type 2 DM rats is more clinically relevant, but such a model has not yet been characterized systematically. The objective of this study was to investigate and characterize how DM affected a full-thickness excision open foot wound in n5-streptozotocin (n5-STZ)-induced type 2 DM rats. We hypothesized that elevated inflammation, reduced blood circulation, and cell proliferation due to hyperglycemia could delay the wound healing of DM rats. The wounds of DM rats were compared with those of non-DM rats (Ctrl) at Days 1 and 8 post wounding. The wound healing process of the DM rats was significantly delayed compared with that of the Ctrl rats. The DM rats also had higher C-reactive protein (CRP) and lower blood circulation and proliferating cell nuclear antigen (PCNA) in DM wounds. This confirmed that elevated inflammation and reduced blood flow and cell proliferation delayed foot wound healing in the n5-STZ rats. Hence, this open foot wound animal model provides a good approach to study the process of delayed wound healing. PMID:28413186

    Abdominal pocketing is one of the most useful methods in salvation of compromised replanted fingertips. Abdominal pocketing has generally been performed in the ipsilateral lower abdominal quadrant, but we have also performed contralateral pocketing at our institute. To determine which approach is more beneficial, a total of 40 patients underwent an abdominal pocketing procedure in either the ipsilateral or contralateral lower abdominal quadrant after fingertip replantation. Dates of abdominal pocketing after initial replantation, detachment after abdominal pocketing, range of motion (ROM) before abdominal pocketing, and sequential ROM after the detachment operation and date of full ROM recovery and Disabilities of Arm, Shoulder, and Hand questionnaire (DASH) score were recorded through medical chart review. Mean detachment date, mean abduction of shoulder after the detachment operation, and mean days to return to full ROM were not significantly different between the ipsilateral and contralateral pocketing groups. However, the mean DASH score was significantly lower in the contralateral group than the ipsilateral group. There were also fewer postoperative wound complications in the contralateral group than in the ipsilateral group. We, therefore, recommend contralateral abdominal pocketing rather than ipsilateral abdominal pocketing to increase patient comfort and reduce pain and complications. PMID:25379539

  1. Lead Thickness Measurements

    Rucinski, R.

    1998-01-01

    The preshower lead thickness applied to the outside of D-Zero's superconducting solenoid vacuum shell was measured at the time of application. This engineering documents those thickness measurements. The lead was ordered in sheets 0.09375-inch and 0.0625-inch thick. The tolerance on thickness was specified to be +/- 0.003-inch. The sheets all were within that thickness tolerance. The nomenclature for each sheet was designated 1T, 1B, 2T, 2B where the numeral designates it's location in the wrap and 'T' or 'B' is short for 'top' or 'bottom' half of the solenoid. Micrometer measurements were taken at six locations around the perimeter of each sheet. The width,length, and weight of each piece was then measured. Using an assumed pure lead density of 0.40974 lb/in 3 , an average sheet thickness was calculated and compared to the perimeter thickness measurements. In every case, the calculated average thickness was a few mils thinner than the perimeter measurements. The ratio was constant, 0.98. This discrepancy is likely due to the assumed pure lead density. It is not felt that the perimeter is thicker than the center regions. The data suggests that the physical thickness of the sheets is uniform to +/- 0.0015-inch.

    Subclinical hypothyroidism (SH) is associated with cardiovascular metabolic syndromes, especially dislipidemia and abdominal obesity. Visceral abdominal adipose tissue (VAAT) and epicardial adipose tissue (EAT) have the same ontogenic origin and produce many proinflammatory and proatherogenic cytokines. We evaluated EAT and VAAT thickness in patients with SH. Forty-one patients with SH and 35 controls were included in the study. Demographical and anthropometric features of both patients and controls were recorded. Thyroid and metabolic parameters were measured. EAT was measured using 2D-transthoracic echocardiography. The age and gender distributions were similar in the two groups (P = 0.998 and P = 0.121, respectively). Body mass index (BMI), fat mass, waist circumference (WC), hip circumference (HC), the WC/HC ratio, and the thicknesses of VAAT and abdominal subcutaneous adipose tissue were higher in the case group than the control group (all P values 0.05). We found no difference between the two groups in fasting plasma glucose (FPG) level (P = 0.780), but the levels of LDL-C and TG differed significantly (P = 0.002 and P = 0.026, respectively). The serum TSH level was higher and the FT4 level was lower in the case than the control group (both P values <0.01). Increased abdominal adipose tissue thickness in patients with SH is associated with atherosclerosis. To detemine the risk of atherosclerosis in such patients, EAT measurements are valuable; such assessment is simple to perform.

    Ibrahim Massuqueto Andrade Gomes de Souza

    Full Text Available Introduction: Appendicitis is a common cause of acute abdomen; however, the classic clinical signs are not often present, and it has unusual presentations. Thus, its diagnosis can be challenging. PRESENTATION OF CASE: We describe the case of an elderly man who presented with right abdominal wall abscess with spontaneous drainage in the emergency department. Since we suspected a subjacent abdominal pathology, we performed surgery, and intraoperatively, we observed that the Appendix tip had invaded the abdominal wall. Discussion: This patient had a challenging diagnostic process and surgical visualization of the appendicular tip invading the abdominal wall was an important characteristic in proving the cause of the abdominal wall abscess. Conclusion: The onset of an abdominal wall abscess without a known cause needs to be thoroughly investigated, with consideration of a subjacent abdominal cause and appendicitis necessitatis. Keywords: Appendicitis, Abdominal abscess, Appendicitis necessitatis, Case report

  7. Does intra-abdominal fluid increase the resting energy expenditure?

    Science.gov (United States)

    Zarling, E J; Grande, A; Hano, J

    1997-10-01

    In patients with intra-abdominal fluid collection, caloric needs are based on an estimated dry weight. This is done because intra-abdominal fluid has been assumed to be metabolically inactive. One recent study of patients with slowly resolving ascites suggested otherwise. In our study, the effect of intra-abdominal fluid on the resting energy expenditure (REE) and apparent lean body mass was determined in 10 stable patients requiring peritoneal dialysis. For each subject, in both the empty and full state, we measured REE by indirect calorimetry, and body composition by the bioelectric impedance method. In the full state, the VCO2 was significantly increased (210 +/- 11 versus 197 +/- 9 mL/min, P empty state. This caused an increase in the calculated resting energy expenditure (1531 +/- 88 kcal/d empty versus 1593 +/- 94 kcal/d full, P calories derived from glucose absorbed out of the dialysate. Estimates of body fat, lean body mass, and total water also were not affected by the intra-abdominal fluid. We conclude that intra-abdominal fluid will not affect the measured REE and hence may be considered to be metabolically inactive.

  8. Education and "Thick" Epistemology

    Kotzee, Ben

    2011-01-01

    In this essay Ben Kotzee addresses the implications of Bernard Williams's distinction between "thick" and "thin" concepts in ethics for epistemology and for education. Kotzee holds that, as in the case of ethics, one may distinguish between "thick" and "thin" concepts of epistemology and, further, that this distinction points to the importance of…

    1995-01-01

    A thick film hydrogen sensor element includes an essentially inert, electrically-insulating substrate having deposited thereon a thick film metallization forming at least two resistors. The metallization is a sintered composition of Pd and a sinterable binder such as glass frit. An essentially inert, electrically insulating, hydrogen impermeable passivation layer covers at least one of the resistors.

  10. [Gallbladder contractility in children with functional abdominal pain or irritable bowel syndrome].

    2013-07-01

    III Rome Criteria of functional gastrointestinal disorders in children, distinguished the disturbances with abdominal pain, to which irritable bowel syndrome, functional abdominal pains, functional dyspepsia and abdominal migraine were included. THE AIM OF THE STUDY was sonographic assessment of the gallbladder and its contractility in functional abdominal pain and irritable bowel syndrome in children. The study comprised 96 children aged 6 to 18 years, 59 girls and 37 boys. Depending on diagnosis, the children were divided into three groups. 38 children with functional abdominal pain constituted the first group, 26 children with irritable bowel syndrome were included to the second group, the third group consisted of 32 healthy children (control group). Diagnosis of functional abdominal pain and irritable bowel syndrome was made based on the III Rome Criteria. In irritable bowel syndrome both forms with diarrhea (13) and with constipation (13) were observed. Anatomy and contractility of the gallbladder were assessed by ultrasound examination. The presence of septum, wall thickness, thick bile, vesicle volume in fasting state and 30th and 60th minute after test meal were taken into consideration. Test meal comprised about 15% of caloric requirement of moderate metabolism. Children with bile stones and organic diseases were excluded from the study. Thickened vesicle wall and thick bile were present more frequently in children with irritable bowel syndrome and functional abdominal pain than in control group (p functional abdominal pain than in irritable bowel syndrome and control group (p = 0.003, p = 0.05). Vesicle contractility after test meal was greatest in children with functional abdominal pain. Evaluation of diminished (smaller than 30%) and enlarged (greater then 80%) gallbladder contractility at 30th and 60th minute after test meal demonstrated disturbances of contractility in children with irritable bowel syndrome and functional abdominal pain.

    Objective: An evaluation of CT diagnosis of abdominal trauma. Methods: CT appearance of abdominal trauma was analyzed retrospectively in 95 cases. thirty-three patients were cured by operation, and the other 59 patients received conservative treatment. Fifty-one patients out of 59 were seen healed or improved by a follow up CT scan after the conservative treatment. Results: The study included: 31 cases of splenic contusion, accompanying with hemoperitoneum in 25 cases; 3 cases of hepatic laceration; 33 cases of liver and spleen compound trauma accompanying with hemoperitoneum; 18 cases of renal contusion, with subcapsular hemorrhage in 12 cases; 4 cases of midriff colic; 3 cases of mesentery breach; 3 cases of digestive tract perforation. Conclusion: CT is sensitive and precise in evaluating abdominal trauma, providing important information for treatment. (author)

  12. Abdominal radiation causes bacterial translocation

    International Nuclear Information System (INIS)

    Guzman-Stein, G.; Bonsack, M.; Liberty, J.; Delaney, J.P.

    1989-01-01

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa

  15. Contemporary imaging in abdominal emergencies

    International Nuclear Information System (INIS)

    Sivit, Carlos J.

    2008-01-01

    Imaging is often a fundamental part in the evaluation of an injured or ill child. A variety of imaging modalities (radiography, angiography/fluoroscopy, sonography, CT, magnetic resonance imaging and scintigraphy) are among the options. CT is worth focused attention because of its usefulness in a variety of emergency department settings, its increasing use, and its potential radiation risks. CT plays an important role in the evaluation of traumatic and nontraumatic abdominal emergencies in children. Therefore, the goal of this paper is to review current imaging approaches and controversies in the evaluation of common acute abdominal emergencies. Through discussion of various modalities, especially CT in evaluation of abdominal pain and trauma, the relative advantages and disadvantages including radiation risk will be reviewed. (orig.)

    Eun, Hyo Won; Kim, Mi Sung; Kang, Beoung Chul; Lee, Sun Wha

    1998-01-01

    The purpose of this study was to describe the ultrasonographic features and assess the diagnostic value of sonography in the evaluation of children with Henoch-Schonlein purpura. Between October 1993, and Febuary 1998, 67 children with Henoch-Schonlein purpura underwent abdominal ultrasonography, which in 13 was used for follow up. Bowel wall thickness and location, pattern of color Doppler signal in the thickened bowel wall, the size and location of enlarged mesenteric lymph node and the presence of ascites were evaluated. In 42 cases(63%), sonographic findings were positive, and indicated mesenteric lymphadenopathy(n=3D21), small bowel wall thickening(n=3D20), and ascites(n=3D17). Thickened bowels were demonstrated at the ileum in 11 cases, the jejunum in five, the duodenum in one, and combined wall thickening at the duodenum and jejunum in two;thickening of the duodenum and ileum was seen in one case. Thickness varied from 3 to 10 mm(mean:6.5 mm). On follow-up sonography, regression of bowel wall thickening was observed earlier than that of mesenteric lymphadenopathy or ascites, and correlated well with improved abdominal symptoms. Abdominal ultrasonographic manifestations of Henoch-Schonlein purpura were bowel wall thickening, mesentric lymphadenopathy and ascites. Sonography was a simple and useful method for the evaluation of gastrointestinal manifestation of Henoch-Schonlein purpura.=20
