    The technique of CT arteriography was introduced, and CT images of the upper abdomen were explained. Very clear enhancement of parenchyma and vessels (especially portal vein) of the object organs could be obtained by CT arteriography of the upper abdomen, anatomical structures of organs were identified more easily by CT arteriography than by conventional CT, and the amount of information obtained was increased by using CT arteriography. However, the indication of CT arteriography must be limited, because of its complexity that CT arteriography is performed after angiography and involves the invasion of patients' bodies. As described in many reports, CT arteriography is useful for malignant tumors of the liver, and it is worthwhile, especially when surgery for hepatocellular carcinoma is considered. CT arteriography for organs except the liver has not been discussed sufficiently. Therefore, an application of this method for other organs must be decided after consideration of the balance of the amount of information obtained by CT arteriography with invasion to patients.

    A 35-year-old male farmer came in contact with 11,000 volts high tension electric wire and sustained full thickness burn wounds over scapula, upper limb and anterior abdominal wall along with perforation of the intestine. Patient was initially managed conservatively in general surgery ward and was referred to us after 3 days with necrosis of the burned skin and muscles over the shoulder and abdomen. Patient was initially managed conservatively and then thorough debridement of the necrotic skin over the left shoulder and upper arm was done and the area was split skin grafted. Patient developed enterocutaneous fistula, which healed over a period of 8 weeks. The granulating wound over the abdomen was also skin grafted and patient was discharged after 18 days. About 4 months, after the discharge patient presented with ventral hernia. Repair of ventral hernia by synthetic mesh application and reconstruction of the abdominal wall with a free tensor fascia lata flap was done over the mesh, but the flap failed. Then after debridement two random pattern transposition skin flaps, one from the right upper and another from the left lower abdomen were transposed over the abdominal wound and donor area was skin grafted. Patient was discharged after 17 days.

    Nowadays, most Belgian patients with type 1 diabetes use flash glucose monitoring (FreeStyle Libre [FSL]; Abbott Diabetes Care, Alameda, California) to check their glucose values, but some patients find the sensor on the upper arm too visible. The aim of the present study was to compare the accuracy and precision of FSL sensors when placed on different sites. A total of 23 adults with type 1 diabetes used three FSL sensors simultaneously for 14 days on the upper arm, abdomen and upper thigh. FSL measurements were compared with capillary blood glucose (BG) measurements obtained with a built-in FSL BG meter. The aggregated mean absolute relative difference was 11.8 ± 12.0%, 18.5 ± 18.4% and 12.3 ± 13.8% for the arm, abdomen (P = .002 vs arm) and thigh (P = .5 vs arm), respectively. Results of Clarke error grid analysis for the arm and thigh were similar (zone A: 84.9% vs 84.5%; P = .6), while less accuracy was seen for the abdomen (zone A: 69.4%; P = .01). Apart from the first day, the accuracy of FSL sensors on the arm and thigh was more stable across the 14-day wear duration than accuracy of sensors on the abdomen, which deteriorated mainly during week 2 (P < .0005). The aggregated precision absolute relative difference was markedly lower for the arm/thigh (10.9 ± 11.9%) compared with the arm/abdomen (20.9 ± 22.8%; P = .002). Our results indicate that the accuracy and precision of FSL sensors placed on the upper thigh are similar to the upper arm, whereas the abdomen performed unacceptably poorly. © 2018 John Wiley & Sons Ltd.

    Stab wounds to the thorax and upper abdomen have the potential to cause pneumothorax (PTX). When a CXR (CXR) obtained during initial resuscitation is negative, a second CXR (CXR-2) is commonly performed with the goal of identifying delayed PTX. To assess the diagnostic yield of the CXR-2 in identifying delayed PTX. Prospective observational study of patients (age >or=13 years) with stab wounds to the thorax (chest/back) and upper abdomen with suspected PTX, in a level 1 trauma centre. Patients were included if they had a negative initial CXR followed by a repeat CXR 3-6h after the initial one. patients who died, were transferred out of the ED, or received chest tubes before the second CXR. The outcome of interest was delayed PTX. All CXR were read by an attending radiologist. To test the inter-observer agreement, another blinded radiologist reviewed 20% of CXR. Continuous data is presented as mean+/-standard deviation and categorical data as percentages with 95% confidence interval (CI). Kappa statistics were used to measure the inter-observer agreement between radiologists. Between January 2003 and December 2006 a total of 185 patients qualified for the enrollment (mean age: 28+/-10 years, age range: 13-65, 94% male). Only 2 patients (1.1%, 95% CI, 0.4- 4.1%) had PTX on the CXR-2. Both patients received chest tubes. The inter-observer agreement for radiology reports was high (kappa: 0.79). Occurrence of delayed PTX in patients with stab wounds to the thorax and upper abdomen and negative triage CXR is rare.

    Full Text Available Spontaneous spleen rupture is a rare complication of infectious diseases and it can become a potentially life-threatening condition if not diagnosed in time. A 17-year-old Greek female presented to the ER due to acute abdominal pain, mainly of the left upper quadrant. She had no recent report of trauma. The patient was pale, her blood pressure was 90/70 mmHg, and her pulse was 120 b/min. Clinical examination of the abdomen revealed muscle contraction and resistance. The patient was submitted to an ultrasound of the upper abdomen and to a CT scanning of the abdomen that revealed an extended intraperitoneal hemorrhage due to spleen rupture. Due to the patient’s hemodynamic instability, she was taken to the operation room and splenectomy was performed. Following a series of laboratory examinations, the patient was diagnosed to be positive for current cytomegalovirus infection. The postoperative course was uneventful, and in a two year follow-up the patient is symptom-free. Spontaneous spleen rupture due to Cytomegalovirus infection is a rare clinical entity, described in few case reports in the world literature and should always be taken into consideration in differential diagnosis of acute abdomen, especially in adolescents with no recent report of trauma.

    Full Text Available Accessory spleens are found in 10–30% of patients and are asymptomatic. Rarely, torsion of an accessory spleen can cause abdominal pain and acute abdomen. We present the case of an 8-year-old girl who arrives to the emergency room with left upper quadrant abdominal pain. CT scan revealed a non-enhancing soft tissue mass and multiple small splenules. Laparoscopy revealed a torsed accessory spleen and malrotation. Accessory spleen is a common congenital anomaly that is frequently asymptomatic. Rarely, an accessory spleen may become torsed around its vascular pedicle resulting in severe abdominal pain. Treatment is surgical resection. Torsion of accessory splenic tissue is a rare cause of acute abdomen in pediatric patients.

    Full Text Available The differential diagnosis of dyspnea in Emergency Department (ED patients is broad and atelectasis is one of the differentials among these. We present a 29-year-old women presented to our ED for evaluation of shortness of breath. On her chest examination, air entry and breath sounds were diminished on the left side but normal on the right. A posteroanterior chest radiograph showed radioluscent area in the upper zone of the left lung, around the aortic arch and also hyperdens area neighbouring this, like covered by a veil. Luftsichel sign together with this hiperdensity were consistent with the diagnose of left lung upper lobe collapse. The Luftsichel sign represents the hyperexpanded superior segment of the left lower lobe interposed between the atelectatic left upper lobe and aortic arch. Patient was discharged to home with chest physiotherapy and breathing exercises together with analgesic prescreption.

    Purpose: To evaluate the safety and diagnostic efficacy of two different doses of ferric ammonium citrate as a paramagnetic oral contrast agent for MR imaging of the upper abdomen. Material and methods: Ninety-nine adult patients referred for MR imaging for a known or suspected upper abdominal pathology were included in this randomized multicenter double-blind clinical trial. Imaging was performed with spin-echo (T1- and T2-weighted) and gradient-echo (T1-weighted) techniques before and after administration of either 1200 mg or 2400 mg of ferric ammonium citrate dissolved in 600 ml of water. Safety analysis included monitoring of vital signs, assessment of adverse events, and laboratory testing. Efficacy with regard to organ distension, contrast distribution, bowel enhancement and delineation of adjacent structures was graded qualitatively. Results: No serious adverse events were reported for either of the two concentrations. A total of 31 minor side effects were noted, of which significantly more occurred in the higher dose group (p<0.01). The diagnostic confidence in defining or excluding disease was graded as better after contrast administration for 48% of all images. Marked or moderate enhancement of the upper gastrointestinal tract was achieved at both doses in 69.5% of cases with no evident difference between the two doses. The higher dose tended to show better results in terms of the contrast assessment parameters. Conclusion: Ferric ammonium citrate is a safe and effective oral contrast agent for MR imaging of the upper abdomen at two different dose levels. The higher dose showed a tendency toward better imaging results while the lower dose caused significantly fewer side effects. Therefore, the 1200 mg dose can be recommended in view of the risk-to-benefit ratio. (orig.)

  13. The Appropriateness of the Length of Insulin Needles Based on Determination of Skin and Subcutaneous Fat Thickness in the Abdomen and Upper Arm in Patients with Type 2 Diabetes

    Full Text Available BackgroundLonger needle and complicated insulin injection technique such as injecting at a 45-degree angle and making skinfolds may decrease patient compliance to insulin injection therapy. In this light, shorter insulin needles have been recently developed. However, it is necessary to ascertain that such shorter needles are appropriate for Korean patients with diabetes as well.MethodsFirst, the diverse demographic and diabetic features of 156 Korean adults with diabetes were collected by a questionnaire and a device unit of body fat measurement. The skin and subcutaneous fat thicknesses of each subject were measured by Ultrasound device with a 7- to 12-MHz probe. Data were analyzed using analysis of variance and multiple linear regression.ResultsThe mean skin thickness was 2.29±0.37 mm in the abdomen and 2.00±0.34 mm in the upper arms, and the mean subcutaneous fat thickness was to 10.15±6.54 mm in the abdomen and 5.50±2.68 mm in the upper arms. Our analysis showed that the factors affecting the skin thickness of the abdomen and upper arms were gender and body mass index (BMI, whereas the factors influencing the subcutaneous fat thickness in the abdomen were gender and BMI, and the factors influencing the subcutaneous fat thickness in the upper arms were gender, BMI, and age. Insulin fluids may not appear to be intradermally injected into the abdomen and upper arms at any needle lengths. The risk of intramuscular injection is likely to increase with longer insulin needles and lower BMI.ConclusionIt is recommended to fully inform the patients about the lengths of needles for insulin injections. As for the recommended needle length, the findings of this study indicate that needles as short as 4 mm are sufficient to deliver insulin for Korean patients with diabetes.

    The lower abdominal obesity is more resistant to absorption as compared to that of upper abdomen. Differences in the physicochemical properties of the subcutaneous fat of the upper and lower abdomen may be responsible for this variation. There is paucity of the scientific literature on the physicochemical properties of the subcutaneous fat of abdomen. The present study was undertaken to create a database of physicochemical properties of abdominal subcutaneous fat. The samples of subcutaneous fat from upper and lower abdomen were collected from 40 fresh autopsied bodies (males 33, females 7). The samples were prepared for physicochemical analysis using organic and inorganic solvents. Various physicochemical properties of the fat samples analysed were surface tension, viscosity, specific gravity, specific conductivity, iodine value and thermal properties. Data was analysed by paired and independent sample t-tests. There was a statistically significant difference in all the physicochemical parameters between males and females except surface tension (organic) and surface tension (inorganic) of upper abdominal fat, and surface tension (organic) of lower abdominal fat. In males, viscosity of upper abdominal fat was more compared to that of lower abdomen (both organic and inorganic) unlike the specific conductivity that was higher for the lower abdominal fat as compared to that of the upper abdomen. In females there were statistically significant higher values of surface tension (inorganic) and specific gravity (organic) of the upper abdomen fat as compared to that of lower abdomen. The initial and final weight loss of the lower abdominal fat as indicated by Thermo Gravimetric Analysis was significantly more in males than in female. The difference in the physicochemical properties of subcutaneous fat between upper and lower abdomen and between males and females could be responsible for the variant behaviour of subcutaneous abdominal fat towards resorption.

  15. How to deal with an open abdomen?

    Appropriate open abdomen treatment is one of the key elements in the management of patients who require decompressive laparotomy or in whom the abdomen is left open prophylactically. Apart from fluid control and protection from external injury, fluid evacuation and facilitation of early closure are now the goals of open abdomen treatment. Abdominal negative pressure therapy has emerged as the most appropriate method to reach these goals. Especially when combined with strategies that allow progressive approximation of the fascial edges, high closure rates can be obtained. Intra-abdominal pressure measurement can be used to guide the surgical strategy and continued attention to intra-abdominal hypertension is necessary. This paper reviews recent advances as well as identifying the remaining challenges in patients requiring open abdomen treatment. The new classification system of the open abdomen is an important tool to use when comparing the efficacy of different strategies, as well as different systems of temporary abdominal closure.

    The use of ultrasound in veterinary medicine is widespread as a diagnostic supplement in the clinical routine of small animals, but there are few reports in wild animals. The objective of this study was to describe the anatomy, topography and abdominal sonographic features of coatis. The urinary bladder wall measured 0.11 ± 0.03 cm. The symmetrical kidneys were in the left and right cranial quadrant of the abdomen and the cortical, medullary and renal pelvis regions were recognized and in all sections. The medullary rim sign was visualized in the left kidney of two coatis. The liver had homogeneous texture and was in the cranial abdomen under the rib cage. The gallbladder, rounded and filled with anechoic content was visualized in all coatis, to the right of the midline. The spleen was identified in the left cranial abdomen following the greater curvature of the stomach. The parenchyma was homogeneous and hyperechogenic compared to the liver and kidney cortex. The stomach was in the cranial abdomen, limited cranially by the liver and caudo-laterally by the spleen. The left adrenal glands of five coatis were seen in the cranial pole of the left kidney showing hypoechogenic parenchyma without distinction of cortex and medulla. The pancreas was visualized in only two coatis. The left ovary (0.92 cm x 0.56 cm) was visualized on a single coati in the caudal pole of the kidney. The uterus, right adrenal, right ovary and intestines were not visualized. Ultrasound examination of the abdomen of coatis may be accomplished by following the recommendations for dogs and cats. It is possible to evaluate the anatomical and topographical relationships of the abdominal organs together with the knowledge of the peculiarities of parenchymal echogenicity and echotexture of the viscera.

    Full Text Available Abstract Background Pulmonary visceral subpleural hematoma is rare. We report visceral subpleural hematoma of the left diaphragmatic surface following left upper division segmentectomy. This very rare case was difficult to distinguish from thoracic abscess. Case presentation A 68-year-old man with hypertension had undergone video-assisted thoracoscopic left upper division segmentectomy for suspected lung carcinoma. Deep vein thrombosis of the lower leg was identified and edoxaban, a so-called novel oral anticoagulant, was started on postoperative day 7. The chest drainage tube was removed on postoperative day 12 because of persistent air leakage, but fever appeared the same day. Computed tomography revealed a cavity with mixed air and fluid, so antibiotics were started on suspicion of abscess. Computed tomography-guided drainage was attempted, but proved unsuccessful. Fever continued and surgical investigation was therefore performed. Visceral subpleural hematoma was identified under the diaphragmatic surface of the left basal lung. We excised the pleura, then performed drainage and applied running sutures. The parenchyma and visceral pleura were covered with polyglycolic acid sheet and fibrin glue. Edoxaban was restarted on postoperative day 12 of video-assisted thoracoscopic surgery and no recurrence of hematoma has been revealed. Conclusions Visceral subpleural hematoma after thoracic surgery is extremely rare. Furthermore, correct diagnosis was difficult and surgery offered a good diagnostic and therapeutic procedure.

    Diagnostic Reference Levels are used to optimize patient dose and image quality in the clinical setting. It is assumed that the majority of exams are of diagnostic quality, or the radiologists would request protocol adjustments. By investigating the dose indicator distributions from all scanners, the upper DRL can be set to the 75th percentile of the distribution and a lower DRL can be set to the 10th percentile. Scanners using doses consistently outside the upper/lower DRL range can be adjusted accordingly. 11 CT scanners, all contributing to the American College of Radiology Dose Index Registry (ACR DIR) were used in this study. Dose indicator data were compiled from the ACR DIR data and local DRLs established. Scanners with median doses outside the upper/lower DRL were followed-up with. Using effective dose and exam volumes, collective dose was determined before and after protocol adjustments to evaluate the effect of this quality improvement effort. The quality initiative is complete for L-spine and Chest/Abdomen/Pelvis exams and only initial surveys were completed for Head and Abdomen/Pelvis examsg. Median Scanner Dose reductions were 8.8 and 4.9 % for L-spine and Chest/Abdomen/Pelvis exams, respectively, resulting with collective dose reductions of 0.7 and 3.2 person•Sv/yr. Follow-up is ongoing for Abdomen/Pelvis and Head exams.

    To evaluate the distance between both upper love bronchi on lateral radiographs and its change in left upper or lower lobe collapse. 144 true lateral radiographs were analyzed on which both upper lobe bronchi were clearly identified. They included 116 normal cases, 11 cases of left upper lobe collapse, 13 of left lower lobe collapse, and 4 cases of left lower lobe lobectomy. Line A was drawn parallel to the vertebral end plate through the upper margin of the lift upper lobe bronchus. Line B was drawn parallel to line A through the upper margin of the right upper love bronchus. The shortest distance between line A and line B was measured as the distance between both upper lobe bronchi. In normal cases, the mean value of the distance was 2.19 cm ± S.D. 0.37 cm on right and on right and 2.16 cm ± S.D. 0.40 cm on left lateral radiographs ; these results were not significantly different(P=0.79). In cases of collapse, the mean value of the distance was 0.43 cm ± S.D. 0.99 cm in upper lobe collapse and 3.56 cm ± S.D. 0.72 cm in lower lobe collapse, results which were significantly different from those of normal cases(p<0.01). In eight cases(73%) of left upper lobe collapse, the distance was less than 1 cm and in 10 cases(77%) of left lower lobe collapse, the distance was more than 3 cm. The distance between both upper lobe bronchi varies markedly in case of lobar collapse. A distance of less than 1 cm suggests collapse of the left upper lobe and a distance more than 3 cm suggests collapse of the left lower lobe

    The aim of this study was to analyze the reason for variation of image quality in the upper abdomen CT with the use of CT-automatic exposure control (AEC). The CT investigated was 3D modulation in the 16 multi detector row CT (MDCT) and lung cancer screening CT (LSCT) phantom was used to simulate the patient. When there was a phase difference, an image noise increase of around 15% at the maximum was accepted. It is concluded that the major reason for variation in image quality is respiratory motion and the importance of respiration control must be recognized. (author)

    The advent of multi-slice CT is one of the quantum leaps in computed tomography since the introduction of helical CT. Multi-slice CT can rapidly scan a large longitudinal (z-axis) volume with high longitudinal resolution and low image artifacts. The rapid volume coverage speed of multi-slice CT can increase the difficulty in optimizing the delay time between the beginning of contrast material injection and the acquisition of images and we need accurate knowledge about optimal temporal window for adequate contrast enhancement. High z-axis resolution of multi-slice can improve the quality of three-dimensional images and MPR images and we must select adequate slice thickness and slice intervals in each case. We discuss basic considerations for adequate contrast enhancement and scanning protocols by multi-slice CT scanner in the upper abdomen. (author)

    Full Text Available Abstract Background Isolated splenic vein thrombosis with left sided portal hypertension is a rare cause of upper gastrointestinal bleed. Diagnosis is difficult and requires a high index of suspicion, especially in patients presenting with gastrointestinal bleed in the presence of splenomegaly and normal liver function tests. Case presentation A 64 year old male presented with haematemesis and melaena. An upper gastrointestinal endoscopy revealed the presence of antral erosions in the stomach and fundal varices. A computerised tomography scan of abdomen confirmed the presence of a diaphragmatic tear and the spleen to be lying in the left hemi thorax. The appearances of the splenic vein on the scan were consistent with thrombosis. Conclusion Left sided portal hypertension as a result of isolated splenic vein thrombosis secondary to trauma is rare. The unusual presentation of our case, splenic herniation into the left hemithorax, causing fundal varices leading to upper gastrointestinal bleed 28 years after the penetrating injury, makes this case most interesting. We believe that this has not been reported in literature before.

    Purpose: The aim of this study was to describe the CT findings of a displaced left upper division bronchus (DLUDB) in adults. Materials and methods: Ten patients with DLUDB were identified. The following CT features were assessed: origin of the DLUDB; distance between the origin of the DLUDB and the origin of the left upper lobe (LUL) bronchus; height of the origin of the DLUDB against the left pulmonary artery (LPA); difference of the main bronchial length; ventilated segment; course of the left pulmonary artery against the DLUDB; and presence of an accessory fissure or other anomalies. Results: DLUDB arose from the posterolateral or lateral aspect of the left main bronchus immediately proximal to the origin of the LUL bronchus. It tended to course along the posterior wall of the LPA and to ventilate the apicoposterior segment with or without the anterior segment. The LPA passed between the displaced bronchus and the lingular bronchus. The origin of the DLUDB was located lower than the inferior wall of the proximal LPA in 6 patients. The accessory fissure between the associated segment and remaining part of the LUL and right tracheal bronchus coexisted in 7 and 3 patients respectively. Conclusion: DLUDB has characteristic findings on CT. Radiologists should be aware of this entity and inform the surgeon as it can prevent serious complications in a patient who may undergo lobectomy of the left lung.

    Full Text Available Left upper division segmentectomy is one of the major pulmonary procedures; however, it is sometimes difficult to completely dissect interlobar lymph nodes. We attempted to clarify the prognostic importance of hilar and mediastinal nodes, especially of interlobar lymph nodes, in patients with primary non-small cell lung cancer (NSCLC located in the left upper division.We retrospectively studied patients with primary left upper lobe NSCLC undergoing surgical pulmonary resection (at least lobectomy with radical lymphadenectomy. The representative evaluation of therapeutic value from the lymph node dissection was determined using Sasako's method. This analysis was calculated by multiplying the frequency of metastasis to the station and the 5-year survival rate of the patients with metastasis to the station.We enrolled 417 patients (237 men, 180 women. Tumors were located in the lingular lobe and at the upper division of left upper lobe in 69 and 348 patients, respectively. The pathological nodal statuses were pN0 in 263 patients, pN1 in 70 patients, and pN2 in 84 patients. Lymph nodes #11 and #7 were significantly correlated with differences in node involvement in patients with left upper lobe NSCLC. Among those with left upper division NSCLC, the 5-year overall survival in pN1 was 31.5% for #10, 39.3% for #11, and 50.4% for #12U. The involvement of node #11 was 1.89-fold higher in the anterior segment than that in the apicoposterior segment. The therapeutic index of estimated benefit from lymph node dissection for #11 was 3.38, #4L was 1.93, and the aortopulmonary window was 4.86 in primary left upper division NSCLC.Interlobar node involvement is not rare in left upper division NSCLC, occurring in >20% cases. Furthermore, dissection of interlobar nodes was found to be beneficial in patients with left upper division NSCLC.

    Twenty adult beagle dogs received intraoperatively delivered 6 MeV electrons to the para-aortic abdomen and bladder. The dogs were equally divided into 4 dose groups receiving 22 Gy, 30 Gy, 38.5 Gy and 47 Gy. The 5 cm x 8 cm radiation field included a variable portion of the left kidney, the left ureter, the abdominal aorta and vena cava, the base of the bladder and the left sciatic and femoral nerves. The lesions observed were fibroelastic proliferation of the aortic intima, severe renal atrophy and fibrosis, ureteral stenosis, bladder fibrosis and demyelinating peripheral neuropathies. Histologic, morphometric and dose response analyses are compared with responses of dogs receiving more conventional fractionated doses to a total of 60 Gy, 70 Gy or 80 Gy x-ray in 6 weeks

    Full Text Available Introduction. Since delay in recognition and effective treatment of necrotizing fasciitis (NF caused by invasive group A streptococcus increases the mortality and disability, the early diagnosis and management of this disease are essential for a better outcome. We presented a patient with a severe form of streptococcal NF of the left upper limb in whom amputation was performed as a life saving procedure. Case report. A 65-year-old man, previously healthy, suffered an injury to his left hand by sting on a fish bone. Two days after that the patient got fever, redness, swelling and pain in his left hand. Clinical examination of the patient after admission indicated NF that spread quickly to the entire left upper limb, left armpit, and the left side of the chest and abdomen. Despite the use of aggressive antibiotic and surgical therapy severe destruction of the skin and subcutaneous tissues developed with the development of gangrene of the left upper limb. In this situation, the team of specialists decided that the patient must be operated on submited to amputation of the left arm, at the shoulder. After amputation and aggressive debridement of soft tissue on the left side of the trunk, the patient completely recovered. β-hemolytic streptococcus group A was isolated from the skin and tissue obtained during the surgery. Conclusion. In the most severe forms of streptococcal NF of the extremities, adequate multidisciplinary treatment, including limb amputation, can save the life of a patient.

    550 Patients were entered into a set of dose-searching studies designed to determine normal tissue tolerances to high energy (42-66 MeV reactions) fast neutrons delivered in 12 equal fractions over 4 weeks. Patients were stratified by treatment facility and then randomized to receive 16, 18 or 20 Gy for tumors located in the upper abdomen or pelvis, and 18, 20 or 22 Gy for tumors located in the head and neck, thorax or extremities. Following completion of the randomized protocols, additional patients were studied at the 20.4 Gy level in the head and neck, thorax and pelvis. Normal tissue effect scoring was accomplished using the RTOG-EORTC acute and late normal tissue effect scales. Acute Grade 3+ toxicity rates in the head and neck were 19 per cent for 20/20.4 Gy and 20 per cent for 22 Gy. Time adjusted late toxicity rates in the head and neck at 12 months were 15 per cent for 20/20.4 Gy and 0 per cent for 22 Gy. The 18 Gy treatment arm of the head and neck protocol was dropped early in the study after only two patients were accrued. For cases treated in the thorax, acute Grade 3+ toxicity rates were 6 per cent for 18 Gy, 15 per cent for 20/20.4 Gy and 7 per cent for 22 Gy. Late toxicity rates at 12 months were 0 per cent for 18 Gy, 11 per cent for 20/20.4 Gy and 18 per cent for 22 Gy. Acute Grade 3+ toxicity rates in the upper abdomen were 0 per cent for 16 Gy, 18 per cent for 18 Gy and 12 per cent for 20 Gy. There were no Grade 3+ late toxicities in the upper abdomen. In the pelvis acute Grade 3+ toxicity rates were 0 per cent for 16 Gy, 3 per cent for 18 Gy and 3 per cent for 20/20.4 Gy. Late Grade 3+ toxicities at 24 months were 20 per cent for 16 Gy, 5 per cent for 18 Gy and 24 per cent for 20/20.4 Gy. In the extremities, acute Grade 3+ toxicity rates were 7 per cent for 20 Gy and 21 per cent for 22 Gy, while at 12 months, late Grade 3+ toxicity rates were 14 and 35 per cent respectively. The 18 Gy treatment arm of the extremities protocol was dropped early

    In patients with a bronchocutaneous fistula, positive pressure ventilation leads to air leakage and potential hypoxemia. A male patient with a right upper bronchocutaneous fistula was scheduled for esophageal reconstruction. His preoperative chest computed tomography image revealed aeration in the right middle and lower lobe, a large bulla in the left upper lobe, and pleural effusion and pneumonia in the left lower lobe. Therefore, left one-lung ventilation was considered to result in hypoxemia. Before anesthesia induction, the bronchocutaneous fistula was covered with gauze and film to prevent air leakage. After anesthesia induction, mask ventilation was performed with a peak positive pressure of 10 cmH 2 O. A left-sided double lumen endobronchial tube (DLT) was then inserted into the right main bronchus for occluding only the right superior bronchus, and two-lung ventilation was performed to minimize airway pressure and maintain oxygenation, which did not cause air leakage through the fistula. During anesthesia, no ventilation-related difficulty was faced. The method of inserting a left-sided DLT into the right main bronchus and occluding the right upper bronchus selectively by bronchial cuff is considered to be an option for mechanical ventilation in patients with a right upper bronchial fistula, as demonstrated in the present case.

    The book first presents the anatomy and physiology of the abdomen and continues with chapters discussing clinical and laboratory aspects and a suitable order of diagnostic examinations with reference to the acute processes, explaining the diagnostic tools: ultrasonography, radiography including angiography and CT, tapping techniques and endoscopy together with their basic principles, examination techniques, and diagnosis. One chapter presents a complete survey of the processes involving the entire abdomen - as e.g. peritonitis, ileus, abdominal trauma, intraperitoneal hemorrage. This chapter profoundly discusses the diagnostics and therapies including emergency measures and surgery. Problems requiring consultation among varous specialists, in internal medicine, gynecology, urology, or pediatrics, are discussed in great detail. Information for the anesthetist is given for cases of emergency. More than one third of the book is devoted to organ-specific information, dicussing the pathogenesis, diagnostics, and therapy of the oesophagus, stomach, large and small intestine, bile ducts, pankreas, liver, spleen, and the abdominal vessels and the abdominal wall.

    Ovarian dysgerminoma cases very rarely present with acute abdomen due to adnexal torsion and the successful laparoscopic management of such a case has not been reported previously. A 17-year-old sexually inactive high school girl presenting with acute abdomen was referred to our emergency department. Transabdominal ultrasonography showed the presence of homogeneous tumor in the lower abdomen. Emergency laparoscopic surgery was performed and left ovarian tumor with adnexal torsion was identified. Left salpingo-oophorectomy was performed carefully to avoid damaging the tumor capsule and the excised tissue was removed after retrieval in an endobag. The histopathological diagnosis was pure ovarian dysgerminoma. The postoperative course was uneventful. Laparoscopic management with careful postoperative follow-up to monitor recurrence could be a treatment option in a young girl with dysgerminoma, if the disease condition is detected in the early stage.

    Aim: To evaluate the advantage of sinogram-affirmed iterative reconstruction (SIR) compared to filtered back projection (FBP) in upper abdomen computed tomography (CT) after transarterial chemoembolisation (TACE) at different tube currents. Materials and methods: The study was approved by the institutional review board. Written informed consent was obtained from all patients. Post-TACE CT was performed with different tube currents successively varied in four steps (180, 90, 45 and 23 mAs) with 40 patients per group (mean age: 60±12 years, range: 23–85 years, sex: 70 female, 90 male). The data were reconstructed with standard FBP and five different SIR strengths. Image quality was independently rated by two readers on a five-point scale. High (Lipiodol-to-liver) as well as low (liver-to-fat) contrast-to-noise ratios (CNRs) were intra-individually compared within one dose to determine the optimal strength (S1–S5) and inter-individually between different doses to determine the possibility of dose reduction using the Kruskal–Wallis test. Results: Subjective image quality and objective CNR analysis were concordant: intra-individually, SIR was significantly (p<0.001) superior to FBP. Inter-individually, regarding different doses (180 versus 23 ref mAs), there was no significant (p=1.00) difference when using S5 SIR at 23 mAs instead of FBP. Conclusion: SIR allows for an 88% dose reduction from 3.43 to 0.4 mSv in unenhanced CT of the liver following TACE without subjective or objective loss in image quality. - Highlights: • Diagnostic image quality and radiation dose of ultra-low-dose CT of the upper abdomen using sinogram affirmed iterative reconstruction following transarterial chemoembolization in comparison to low-dose and standard dose CT and filtered back projection technique. • Ultra-low dose CT of the upper abdomen using sinogram affirmed iterative reconstruction allows for significant dose reduction by 88%. • Ultra-low dose CT of the upper abdomen

    Segmental omental infarction (OI) is a rare cause of abdominal pain in children. It generally occurs in the right lower and upper quadrants of the abdomen and only a few cases of other locations have been described in adults. We report a unique paediatric case of OI with an unusual left-sided location extending into the pelvis in a 6-year-old non-obese girl. The diagnosis was suspected on US and CT based on imaging patterns previously described in adults and children. Laparoscopic resection should be balanced with nonsurgical management. (orig.)

    Full Text Available Abstract Background Acute abdomen in advanced pregnancy is one of the most challenging surgical situations. In life-threatening situations, despite optimal management, foetus distress and preterm delivery may occur. Although laparostomy is a useful treatment of abdominal sepsis, its successful management has not been reported previously in pregnant women. Case 30-year-old woman at 23 week of pregnancy was investigated for non-specific abdominal pain. Surgical exploration revealed extensive ischemic bowel necrosis. Multiple segmental resections were performed and abdomen was left open with vacuum assisted dressing, maintained for 48 hours. At the third surgical look the continuity was restored and abdominal wall closed. The foetal condition stayed unperturbed under pharmacologic tocolysis. Pregnancy was carried to full term delivery. Conclusion Open abdomen strategy can be successfully applied in pregnant woman.

    The diagnostic work-up of adults with acute abdominal pain has changed significantly within the last decade and computed tomography is often used as the first imaging modality of choice. In pediatric patients with an acute abdomen, ultrasound and abdominal X-rays remain the first line procedures. Because of the radiation risk, computed tomography is only recommended in selected cases and when strongly indicated. This review is the fourth and final part within a series of reviews dealing with the diagnostic strategy in the work-up of patients with an acute abdomen. (orig.)

    Full Text Available Objective. To demonstrate the technical feasibility and the potential interest of using a digital optical camera inside the MR magnet bore for monitoring the breathing cycle and subsequently gating the PRFS MR thermometry, MR-ARFI measurement, and MRgHIFU sonication in the upper abdomen. Materials and Methods. A digital camera was reengineered to remove its magnetic parts and was further equipped with a 7 m long USB cable. The system was electromagnetically shielded and operated inside the bore of a closed 3T clinical scanner. Suitable triggers were generated based on real-time motion analysis of the images produced by the camera (resolution 640×480 pixels, 30 fps. Respiratory-gated MR-ARFI prepared MRgHIFU ablation was performed in the kidney and liver of two sheep in vivo, under general anaesthesia and ventilator-driven forced breathing. Results. The optical device demonstrated very good MR compatibility. The current setup permitted the acquisition of motion artefact-free and high resolution MR 2D ARFI and multiplanar interleaved PRFS thermometry (average SNR 30 in liver and 56 in kidney. Microscopic histology indicated precise focal lesions with sharply delineated margins following the respiratory-gated HIFU sonications. Conclusion. The proof-of-concept for respiratory motion management in MRgHIFU using an in-bore digital camera has been validated in vivo.

    2006-01-01

    Purpose: To analyze the influence of different biphasic and monophasic injection rate protocols in abdominal computed tomography (CT). Material and Methods: A randomized, consecutive, parallel group study was designed and conducted in 60 patients studied with the same CT helical protocol. Patients were randomly distributed into three groups: (A) monophasic (120 ml at 2.5 ml/s); (B) low-high biphasic (120 ml, first 60 ml at a rate of 2 ml/s, the other 60 ml at 2.5 ml/s); and (C) high-low biphasic (120 ml, first 60 ml at a rate of 2.5 ml/s, the other 60 ml at 2 ml/s). All patients were injected with 300 mg I/ml non-ionic contrast media at a fixed delay time of 55 s. Contrast enhancement efficacy was evaluated by attenuation coefficient measurements. Results: Although non-significant, monophasic protocol enhancements were higher than biphasic protocol enhancements in all measurements except aortic bifurcation (p = 0.003). At this level, biphasic protocols obtained an increased mean enhancement from 7.6% to 2.5% compared to monophasic protocols. Conclusion: Monophasic contrast agent injection in helical CT of the upper abdomen produces a higher enhancement of parenchymal and venous structures. No significant difference was observed between low-high and high-low biphasic protocols

    Internal herniation is a rare cause of intestinal obstruction, especially in the emergency department. We report a child with acute abdomen resulting from transmesenteric internal herniation of the small bowel. Radiographic findings revealed gaseous distension of the bowel loops in the upper abdominal area with a paucity of gas in the lower abdomen. Operative finding showed gangrenous small bowel due to mesenteric defect with an internal herniation. The gangrenous bowel was resected and the patient was discharged with an uneventful outcome. We emphasize that early recognition of internal herniation warrants further evaluation and appropriate management. Copyright © 2012. Published by Elsevier B.V.

Materials and Methods: Four fetus (two male & two female of four month of intrauterine life were dissected. Attachments & layers of superficial fascia and future subcutaneous fat deposit area of upper and lower abdomen were noted. Results: Superficial fascia of the abdomen was multi layered in mid line and number of layers reduced laterally as in adult. The future abdominal LFD (localized fat deposits area in fetus shows brownish-white blubbary tissue without well-defined adult fat lobules. Conclusion: The attachment and gross anatomy of superficial fascia of the fetus was similar to that in adults. The future LFD areas showed brownish white blubbary tissue with ill-defined fat lobules.

    1) The upper abdominal compression method was easily applicable for CT examination in practically all the patients. It gave no harm and considerably improved CT diagnosis. 2) The materials used for compression were foamed polystyrene, the Mix-Dp and a water bag. When CT examination was performed to diagnose such lesions as a circumscribed tumor, compression with the Mix-Dp was most useful, and when it was performed for screening examination of upper abdominal diseases, compression with a water bag was most effective. 3) Improvement in contour-depicting ability of CT by the compression method was most marked at the body of the pancreas, followed by the head of the pancreas and the posterior surface of the left lobe of the liver. Slight improvement was seen also at the tail of the pancreas and the left adrenal gland. 4) Improvement in organ-depicting ability of CT by the compression method was estimated by a 4-category classification method. It was found that the improvement was most marked at the body and the head of the pancreas. Considerable improvement was observed also at the left lobe of the liver and the both adrenal glands. Little improvement was obtained at the spleen. When contrast enhancement was combined with the compression method, improvement at such organs which were liable to be enhanced, as the liver and the adrenal glands, was promoted, while the organ-depicting ability was decreased at the pancreas. 5) By comparing the CT image under compression with that without compression, continuous infiltrations of gastric cancer into the body and the tail of the pancreas in 2 cases and a retroperitoneal infiltration of pancreatic tumor in 1 case were diagnosed preoperatively.

    Full Text Available Abstract Introduction We report the case of a patient with a benign multicystic peritoneal mesothelioma and describe its appearance on computed tomography scans and ultrasonography, in correlation with gross clinical and pathological findings. Case presentation A 72-year-old Caucasian woman presented to our emergency department with acute abdomen signs and symptoms. A clinical examination revealed a painful palpable mass in her left abdomen. Abdominal ultrasonography and computed tomography demonstrated the presence of a large cystic mass in her left upper abdomen, adjacent to her left hemidiaphragm. The lower border of the mass extended to the upper margin of her pelvis. A complete resection of the lesion was performed. Pathological analysis showed a benign multicystic peritoneal mesothelioma. Conclusions Benign multicystic peritoneal mesothelioma is a rare lesion with a non-specific appearance on imaging. Its diagnosis always requires pathological analysis.

    Acute abdomen is not a disease in itself but a description of a complex of symptoms combined with severe abdominal pain developed within a time frame of less than 24 h. All strategies for the management of acute abdomen underline the need for an interdisciplinary approach to diagnosis and therapy. This requires focused and intelligent use of efficient diagnostic procedures. Diagnostic laparoscopy may be a key to solving the diagnostic dilemma of unspecific acute abdomen. Furthermore, it allows not only direct inspection of the abdominal cavity but also surgical intervention, if needed. In particular the rate of negative laparotomies can be reduced.

    The aim of this study was to describe a minimally invasive laparoscopic jejunostomy (Lap-J) technique for obstruction due to upper gastrointestinal malignancies and evaluate the nutritional benefit of Lap-J during neoadjuvant chemotherapy (NAC) in cases with obstructing esophageal cancer. Under general anesthesia, the jejunum 20–30 cm distant from the Treitz ligament was pulled out through an extended umbilical laparoscopic incision and a jejunal tube was inserted to 30 cm. The loop of bowel was gently returned to the abdomen and the feeding tube was drawn through the abdominal wall via the left lower incision. The jejunum was then laparoscopically sutured to the anterior abdominal wall. Lap-J was performed in 26 cases. The median operative time was 82 min. The postoperative course was uneventful. Lap-J prior to NAC was not associated with a decrease in body weight or serum total protein during NAC, compared with patients who received NAC without Lap-J. This minimally invasive jejunostomy technique may be particularly useful in patients in whom endoscopic therapy is not feasible due to obstruction from upper gastrointestinal malignancies.

    A 49-year-old man was transferred to our hospital by ambulance due to blunt chest trauma sustained in a car accident. Echocardiography and enhanced computed tomography showed hemopericardium without other vital organ damage. Emergent surgery was performed under strong suspicion of traumatic cardiac rupture. Careful inspection showed a rupture of the right upper pulmonary vein at the junction of the left atrium, a laceration of the inferior vena cava, and a left-side pericardium rupture, and they were repaired with running 4-0 polypropylene suture. Postoperative hemodynamics were stable. The patient was discharged ambulatory on postoperative day 15.

    Radiographic evaluation of the abdomen is obtained less often than that of the chest with the postoperative or critically ill patient. Because of the limitations in mobility with these patients, the studies are usually made with a portable radiographic unit and often require considerable assistance from the intensive care unit (ICU) staff. The technologist must use considerable care in obtaining these studies; optimal radiographic technique and careful patient positioning should result in a satisfactory radiograph so that the study will not have to be repeated. If a ''supine abdomen'' film is requested, the technologist will center the film to include the diaphragm; with a ''kidney-ureter-bladder'' film, the pelvis will be included and the diaphragm may not be seen. It is important to have as much clinical information as possible before interpreting any radiographs of the critically ill patient

    The diagnostic work-up of adults with acute abdominal pain has changed significantly within the last decade and computed tomography is often used as the first imaging modality of choice. In pediatric patients with an acute abdomen, ultrasound and abdominal X-rays remain the first line procedures. Because of the radiation risk, computed tomography is only recommended in selected cases and when strongly indicated. This review is the fourth and final part within a series of reviews dealing with the diagnostic strategy in the work-up of patients with an acute abdomen. (orig.)

    Use of damage control surgery techniques has reduced mortality in critically injured patients but at the cost of the open abdomen. With the option of delayed definitive management of enteric injuries, the question of intestinal repair/anastomosis or definitive stoma creation has been posed with no clear consensus. The purpose of this study was to determine outcomes on the basis of management of enteric injuries in patients relegated to the postinjury open abdomen. Patients requiring an open abdomen after trauma from January 1, 2002 to December 31, 2007 were reviewed. Type of bowel repair was categorized as immediate repair, immediate anastomosis, delayed anastomosis, stoma and a combination. Logistic regression was used to determine independent effect of risk factors on leak development. During the 6-year study period, 204 patients suffered enteric injuries and were managed with an open abdomen. The majority was men (77%) sustaining blunt trauma (66%) with a mean age of 37.1 years±1.2 years and median Injury Severity Score of 27 (interquartile range=20-41). Injury patterns included 81 (40%) small bowel, 37 (18%) colonic, and 86 (42%) combined injuries. Enteric injuries were managed with immediate repair (58), immediate anastomosis (15), delayed anastomosis (96), stoma (10), and a combination (22); three patients died before definitive repair. Sixty-one patients suffered intra-abdominal complications: 35 (17%) abscesses, 15 (7%) leaks, and 11 (5%) enterocutaneous fistulas. The majority of patients with leaks had a delayed anastomosis; one patient had a right colon repair. Leak rate increased as one progresses toward the left colon (small bowel anastomoses, 3% leak rate; right colon, 3%; transverse colon, 20%; left colon, 45%). There were no differences in emergency department physiology, injury severity, transfusions, crystalloids, or demographic characteristics between patients with and without leak. Leak cases had higher 12-hour heart rate (148 vs. 125, p=0

    Postoperative hemorrhage is a significant cause of morbidity and mortality following liver resection. It typically presents early within the postoperative period, and conservative management is possible in the majority of cases. We present a case of late post-hepatectomy hemorrhage associated with overt abdominal compartment syndrome resulting from a localized functional compartment within the abdomen. A 68-year-old white man was readmitted with sudden onset of upper abdominal pain, vomiting, and hemodynamic instability 8 days after an uneventful hepatic resection for metachronous colon cancer metastasis. A frozen abdomen with adhesions due to complicated previous abdominal surgeries was encountered at the first intervention, but the surgery itself and initial recovery were otherwise unremarkable. Prompt response to fluid resuscitation at admission was followed by a computed tomography of his abdomen that revealed active arterial hemorrhage in the liver resection site and hemoperitoneum (estimated volume abdominal compartment syndrome. Surgical exploration confirmed a small volume of ascites and blood clots (1.2 L) under significant pressure in his supramesocolic region, restricted by his frozen lower abdomen, which we evacuated. Dramatic improvement in his ventilatory pressure was immediate. His abdomen was left open and a negative pressure device was placed for temporary abdominal closure. The fascia was formally closed after 48 hours. He was discharged home at postoperative day 6. Intra-abdominal pressure and radiologic findings of intra-abdominal hemorrhage should be carefully interpreted in patients with extensive intra-abdominal adhesions. A high index of suspicion and detailed understanding of abdominal compartment mechanics are paramount for the timely diagnosis of abdominal compartment syndrome in these patients. Clinicians should be aware that abnormal anatomy (such as adhesions) coupled with localized pathophysiology (such as hemorrhage) can create a so

    Aberrant origins of the pulmonary artery are rare anomalies, but are being reported several times in the world literature. Among them, pulmonary artery sling is the most well known anomaly, which is the left pulmonary artery arising from the right pulmonary artery. In case of pulmonary artery sling, the left pulmonary artery causes compression of the trachea and esophagus while it courses in between. In this case, we describe a case on incidentally found aberrant origin of the upper left lobe anterior and superior lingular segmental pulmonary artery without any compressions of the esophagus or trachea. In the world literature, aberrant origins of the left pulmonary artery without pulmonary artery sling was reported at one time, but currently, this is the first case of aberrant origin of the upper left lobe anterior and superior lingular segmental pulmonary artery arising from the right pulmonary artery.

    Since acute abdomen requires accurate diagnosis and treatment within a particular time limit to prevent mortality, the Japanese Society for Abdominal Emergency Medicine, in collaboration with four other medical societies, launched the Practice Guidelines for Primary Care of Acute Abdomen that were the first English guidelines in the world for the management of acute abdomen. Here we provide the highlights of these guidelines (all clinical questions and recommendations were shown in supplementary information). A systematic and comprehensive evaluation of the evidence for epidemiology, diagnosis, differential diagnosis, and primary treatment for acute abdomen was performed to develop the Practice Guidelines for Primary Care of Acute Abdomen 2015. Because many types of pathophysiological events underlie acute abdomen, these guidelines cover the primary care of adult patients with nontraumatic acute abdomen. A total of 108 questions based on nine subject areas were used to compile 113 recommendations. The subject areas included definition, epidemiology, history taking, physical examination, laboratory test, imaging studies, differential diagnosis, initial treatment, and education. Japanese medical circumstances were considered for grading the recommendations to assure useful information. The two-step methods for the initial management of acute abdomen were proposed. Early use of transfusion and analgesia, particularly intravenous acetaminophen, were recommended. The Practice Guidelines for Primary Care of Acute Abdomen 2015 have been prepared as the first evidence-based guidelines for the management of acute abdomen. We hope that these guidelines contribute to clinical practice and improve the primary care and prognosis of patients with acute abdomen. © 2015 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    The book first presents the anatomy and physiology of the abdomen and continues with chapters discussing clinical and laboratory aspects and a suitable order of diagnostic examinations with reference to the acute processes, explaining the diagnostic tools: ultrasonography, radiography including angiography and CT, tapping techniques and endoscopy together with their basic principles, examination techniques, and diagnosis. One chapter presents a complete survey of the processes involving the entire abdomen - as e.g. peritonitis, ileus, abdominal trauma, intraperitoneal hemorrage. This chapter profoundly discusses the diagnostics and therapies including emergency measures and surgery. Problems requiring consultation among varous specialists, in internal medicine, gynecology, urology, or pediatrics, are discussed in great detail. Information for the anesthetist is given for cases of emergency. More than one third of the book is devoted to organ-specific information, dicussing the pathogenesis, diagnostics, and therapy of the oesophagus, stomach, large and small intestine, bile ducts, pankreas, liver, spleen, and the abdominal vessels and the abdominal wall.

    A 50-year-old woman was referred to our institution for medical screening due to an incidental finding on abdominal ultrasonography. She underwent chest, abdomen and cardiac multi-detector computed tomography (MDCT). Her MDCT revealed absence of the hepatic segment of the inferior vena cava (IVC), with hemiazygos continuation and a left single coronary artery. The dilated hemiazygos vein drained directly into the persistent left superior vena cava (SVC). Herein, we reported a very rare case combining an incidentally found interrupted IVC with hemiazygos vein continuation, persistent left SVC and a left single coronary artery diagnosed by MDCT.

    We found tumor-like shadows in the upper abdomen in 93 cases out of 400 abdominal plain films, although none of these 93 cases actually had a tumor. We analyzed these tumor-like shadows by computed tomography. For each of the 400 cases we measured the width of flank stripe on the abdominal plain film. Most of the tumor-like shadows in the left upper abdomen were gastric fundus, but it was significant for evaluating plain abdominal film that other organs such as a part of the left lobe of the liver, the upper pole of the left kidney, and a part of the spleen formed tumor-like shadows. The most important factors forming tumor-like shadows on plain abdominal film are the fat volume of the abdominal cauity as well as the fraciform ligament and alterations in the shape and volume of organs such as occur in liver cirrhosis.

    Acute abdomen means a set of clinical emergency with acute abdominalgia as the primary characteristic symptom of onset, including others as the acute onset, quick symptom changes, severe illness, and oftenly need surgical treatment; therefore, acute abdomen ought to be designated within surgery domain. As interventional therapy is extensively applied in clinical medicine, now a days many victims of acute abdomen, especially those with ambiguous clinical diagnosis requiring an initial invasive examination (angiography, PTC, etc), should be referred to interventional therapy before taking an item of invasive measures. This new concept management has achieved good clinical curative effect and become one of the remarkable achievements in acute abdomen therapeutics. Such predominance finds proper expression in the following two aspects: (1) The evolution of contemporary medical iconography has made it possible to duly and accurately diagnose acute abdomen, and thus created a diagnostic predominance for us-interventionalists; (2) Intervention therapy is featured with its unique minimal invasion and massive effectiveness, and thus provides high leading edge than conventional surgical operation. The authors believe that intervention management ought to become the first-choice for treating the above mentioned acute abdomen. (authors)

  7. Delayed rupture of thoracic aorta aneurysm following a kick to the abdomen.

    Several theories have been proposed to explain the Blunt Traumatic Aortic Rupture (BTAR) because different mechanical forces act on the aorta, at anatomically susceptible sites, including shearing, torsion and stretching, but the origin, transduction and relative importance of these forces remain uncertain. We report a case of a 74-year-old man injured by a kick to the abdomen. After 2 days he felt chest pain paroxysm and weakness in his left leg. The patient was admitted to an emergency care department where he experienced sudden and severe hemodynamic deterioration, dying rapidly. The autopsy, performed 3 days later, showed haemorragic infarction of hypogastric subcutaneous tissues and revealed an extended dissecting aneurysm of the thoracic aorta with following haemopericardium. In our case we considered that a low energy compression to the abdomen, in presence of underlying atherosclerosis, caused aortic dissection rather than rupture and then the 48h time span after the traumatic event and the cardiac tamponade was enough to complete the aortic retrograde dissection. We finally emphasise the importance of the careful surveillance of any trauma close to the abdomen in view of initially unpredictable, as well as eventful injuries. The finding of early signs of neointima formation in thoracoabdominal portions of aortic dissection strongly supported our interpretation. The forensic interest of this case is correlated to the voluntary character of the inflicted injury. The culprit was thus charged with manslaughter.

    A 60-year-old male patient with left hilar lung cancer was scheduled to undergo left pneumonectomy or left sleeve lower lobectomy. Preoperative computer tomographic and bronchoscopic examinations revealed that the bronchus (B1) to the right apical segment (S1) was a tracheal bronchus (TB) originating from the trachea approximately 10 mm above the carina. Because the left main bronchus was to be dissected, a right-sided double-lumen tube (DLT) was selected to completely protect the right lung from spillage of secretions or cancer cells from the left lung. The right-sided DLT was placed so as to fit its lateral opening of the bronchial lumen to normal upper branches (B2, B3), while sacrificing ventilation of S1 with an abnormal branch (B1). However, one-lung ventilation (OLV) of the right lung could not be achieved, since a gas leakage from the opened tracheal lumen occurred, most probably due to intra-lobar micro-airway communications between S1 and S2/S3. The DLT was withdrawn until the blue bronchial cuff occluded the orifice of the TB (B1). Although the upper half of the blue bronchial cuff appeared above the tracheal carina, OLV through the two bronchial lumen openings could be achieved due to a specific, slanted doughnut shape of the blue bronchial cuff and the location of the abnormal branch (B1) approximate to the carina. Left pneumonectomy using successful OLV was completed safely without hypoxemia or hypercapnea. Our experience indicates that management of OLV for patients with a thoracheal bronchus needs special considerations of the exact location of the TB and intra-lobar micro-airway communications, in addition to types of scheduled surgical procedures.

    Worldwide accepted indications of anatomical segmentectomies are mainly early stage primary adenocarcinomas, pulmonary metastasis and benign conditions. Their performance through uniportal VATS has become more and more popular due to the less invasiveness of the whole procedure under this approach. Recently, many efforts have focused on non-intubated spontaneously breathing management of lobectomies and anatomical segmentectomies, although specific selection criteria and main advantages are not completely standardized. In a 62-year-old thin man with two pulmonary residual metastasis from sigma adenocarcinoma, after chemotherapy plus antiangiogenic treatment, we indicated a single-incision video-assisted left-lower lobe (LLL) upper segmentectomy (S6) under spontaneous breathing and intercostal blockade. Total operation time was 240 minutes. Chest tube was removed at 24 hours and the patient was discharge on postoperative day 2 without any complication. Non-intubated uniportal VATS is a safe and reasonable approach for lung-sparing resections in selected patients, although more evidence is required for selecting which patients can benefit more over standard intubated procedures.

    Full Text Available Omental torsion leading on to omental infarction is an unusual cause of acute abdominal pain in adults. Often the condition mimics common causes of acute abdomen like acute cholecystitis, acute appendicitis or acute pancreatitis. A review of literature reveals that this enigmatic condition has been managed both non - operatively and by surgery in the past. We report the case of a 46 - year - old man who presented with a 4 - day history of severe right - sided abdominal pain mimicking acute cholecystitis. Abdominal CT scan revealed a right upper quadrant mass with a whirl - like appearance, suspicious for omental infarction. He was started on conservative management with analgesics and antibiotics. He improved symptomatically and was discharged

  14. Prevention of Incisional Hernias after Open Abdomen Treatment

    2018-02-01

    Full Text Available Management of a patient with an open abdomen is difficult, and the primary closure of the fascial edges is essential to obtain the best patient outcome, regardless of the initial etiology of the open abdomen. The use of temporary abdominal closure devices is nowadays the gold standard to have the highest closure rates with mesh-mediated fascial traction as the proposed standard of care. However, the incidence of incisional hernias, although much more controlled than when leaving an abdomen open, is high and reaches up to 65%. As shown for other high-risk patient subgroups, such as obese patients, patients with an abdominal aneurysm, and patients with former -ostomy sites, the prevention of incisional hernias might be key to further optimize patient outcomes after open abdomen treatment. In this overview, current available modalities to decrease the incidence of incisional hernia are discussed. Most of these preventive options have been shown effective in giant ventral hernia repair and might work effectively in this patient cohort with open abdomen as well.

    To compare image quality of turbo spin-echo (TSE) with BLADE [which is also named periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER)] on magnetic resonance imaging (MRI) for upper abdomen. This study involved the retrospective evaluation of 103 patients (63 males, 40 females; age range 19-76 years; median age 53.8 years) who underwent 3.0 T MRI with both conventional TSE T2-weighted imaging (T2WI) and BLADE TSE T2WI. Two radiologists assessed respiratory motion, gastrointestinal peristalsis, and vascular pulsation artifacts, as well as the sharpness of the liver and pancreas edges. Scores for all magnetic resonance (MR) images were recorded. Wilcoxon's rank test was used to compare hierarchical data. Cohen's kappa coefficient was adopted to analyze interobserver consistency. Compared to TSE T2WI, BLADE TSE T2WI reduced all of the examined motion artifacts and increased the sharpness of the liver and pancreas edges (all P image quality.

  16. The optimization of acoustic fields for ablative therapies of tumours in the upper abdomen

    High intensity focused ultrasound (HIFU) enables highly localized, non-invasive tissue ablation and its efficacy has been demonstrated in the treatment of a range of cancers, including those of the kidney, prostate and breast. HIFU offers the ability to treat deep-seated tumours locally, and potentially bears fewer side effects than more invasive treatment modalities such as resection, chemotherapy and ionizing radiation. There remains however a number of significant challenges which currently hinder its widespread clinical application. One of these challenges is the need to transmit sufficient energy through the ribcage to ablate tissue at the required foci whilst minimizing the formation of side lobes and sparing healthy tissue. Ribs both absorb and reflect ultrasound strongly. This sometimes results in overheating of bone and overlying tissue during treatment, leading to skin burns. Successful treatment of a patient with tumours in the upper abdomen therefore requires a thorough understanding of the way acoustic and thermal energy is deposited. Previously, a boundary element approach based on a Generalized Minimal Residual (GMRES) implementation of the Burton-Miller formulation was developed to predict the field of a multi-element HIFU array scattered by human ribs, the topology of which was obtained from CT scan data (Gélat et al 2011 Phys. Med. Biol. 56 5553-81). The present paper describes the reformulation of the boundary element equations as a least-squares minimization problem with nonlinear constraints. The methodology has subsequently been tested at an excitation frequency of 1 MHz on a spherical multi-element array in the presence of ribs. A single array-rib geometry was investigated on which a 50% reduction in the maximum acoustic pressure magnitude on the surface of the ribs was achieved with only a 4% reduction in the peak focal pressure compared to the spherical focusing case. This method was then compared with a binarized apodization approach

  17. Fatal stroke after completion pneumonectomy for torsion of left upper lobe following left lower lobectomy

    Full Text Available Abstract Background The lobar torsion after lung surgery is a rare complication with an incidence of 0.09 to 0.4 %. It may occur after twisting of the bronchovascular pedicle of the remaining lobe after lobectomy, usually on the right side. The 180-degree rotation of the pedicle produces an acute obstruction of the lobar bronchus (atelectasis and of the lobar vessels as well. Without prompt treatment it progresses to lobar ischemia, pulmonary infarction and finally fatal gangrene. Case Presentation A 62 years old female patient was admitted for surgical treatment of lung cancer. She underwent elective left lower lobectomy for squamous cell carcinoma (pT2 N0. The operation was unremarkable, and the patient was extubated in the operating room. After eight hours the patient established decrease of pO2 and chest x-ray showed atelectasis of the lower lobe. To establish diagnosis, bronchoscopy was performed, demonstrating obstructed left lobar bronchus. The patient was re-intubated, and admitted to the operating room where reopening of the thoracotomy was performed. Lobar torsion was diagnosed, with the diaphragmatic surface of the upper lobe facing in an anterosuperior orientation. A completion pneumonectomy was performed. At the end of the procedure the patient developed a right pupil dilatation, presumably due to a cerebral embolism. A subsequent brain angio-CT scan established the diagnosis. She died at the intensive care unit 26 days later. Conclusion The thoracic surgeon should suspect this rare early postoperative complication after any thoracic operation in every patient with atelectasis of the neighboring lobe. High index of suspicion and prompt diagnosis may prevent catastrophic consequences, such as, infarction or gangrene of the pulmonary lobe. During thoracic operations, especially whenever the lung or lobe hilum is full mobilized, fixation of the remaining lobe may prevent this life threatening complication.

    The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis. The objective of this pictorial essay is to review the different imaging techniques used on diagnosing obstructive acute abdomen. (author)

    The open abdomen is increasingly used for the treatment and prevention of abdominal compartment syndrome. The leading non-traumatic conditions that may cause abdominal compartment syndrome requiring surgical decompression include secondary peritonitis, ruptured abdominal aortic aneurysm and severe acute pancreatitis. Patients may also end up with the open abdomen when the laparotomy wound cannot be closed without tension because of excessive visceral swelling. Also, surgical complications such as laparotomy wound dehiscence, may require temporary abdominal closure techniques. In critically ill surgical patients and in situations when second-look laparotomy is mandatory the open abdomen can be utilized in a preventive manner like in damage control trauma surgery. Underlying disease and the indication for the open abdomen significantly contributes to outcome of patient with open abdomen. Non-traumatic aetiology of the open abdomen is associated with lower likelihood of primary fascial closure and higher rate of open abdomen related complications compared with traumatic aetiology. A number of temporal abdominal closure techniques have been described. Ideally, temporal abdominal closure technique should prevent the development of recurrent abdominal compartment syndrome and facilitate later primary fascia closure with low complication rate. Although fascial closure rate varies between techniques, there are few evidence-based data to support one technique over another. However, recent evolution of temporary abdominal closure techniques have decreased the number of patients with frozen abdomen and reduced the need for planned hernia management. Highest fascial closure rates have been achieved with vacuum-assisted closure systems and systems that provide continuous fascial traction.

    Objectives: To study the outcome of intestinal tuberculosis presenting as acute abdomen. Study design: Descriptive Study. Place and Duration: Bolan Medical Complex Hospital (BMC) Quetta and Combined Military Hospital (CMH) Quetta from Nov 2003 to Nov 2005 from Bolan Medical Complex and from Nov 2005 to Nov 2006 in CMH Quetta. Material and Method: Thirty seven patients of acute abdomen presenting with intestinal obstruction were admitted; 28 from emergency department and 9 from out patient department. Twenty seven patients were from BMC and 10 from CMH Quetta. Patients were diagnosed as having abdominal tuberculosis on the basis of operative findings and histopathological reports. Results: Out of 37 patients presenting with acute abdomen due to intestinal obstruction, 54% were male and 46% were female with M: F ratio of 1: 1.2. Age of the patient ranged from 20 to 50 years, with maximum frequency between 30 to 40 years. Abdominal pain was the commonest presenting feature in all patients followed by constipation in 81.1% patients. Peritonism was seen in 27% patients. Different operative procedures performed were adhesionolysis 65.8%, segmental resection 7.9%, right hemicolectomy 10.5%, stricturoplasty 7.9% and ileostomy 1.3%. Mesenteric lymph node biopsy 40.8%. Conclusion: Intestinal tuberculosis is still a very important surgical problem in our country presenting as acute abdomen. A suspicion must always be kept during laparotomy and adequate tissue histopathology should supplement the diagnosis. (author)

    The efficacy of high intensity focused ultrasound (HIFU) for the non-invasive treatment of cancer has been demonstrated for a range of different cancers including those of the liver, kidney, prostate and breast. As a non-invasive focused therapy, HIFU offers considerable advantages over other techniques such as chemotherapy and surgical resection, in terms of its non-invasiveness and low risk of harmful side effects. There is, however, a number of significant challenges which currently hinder its widespread clinical application. One of these challenges is the need to transmit sufficient energy through the ribcage to induce tissue necrosis at the required foci whilst minimising the formation of side lobes and sparing healthy tissue. Ribs both absorb and reflect ultrasound strongly. As such, a common side effect of focusing ultrasound in regions located behind the rib cage is the overheating of bone and surrounding tissue, which can lead to skin burns. Successful treatment of a patient with tumours in the upper abdomen therefore requires a thorough understanding of the way acoustic and thermal energy are deposited. This is likely to rely on a treatment planning procedure in which optimal source velocity distributions are obtained so as to maximise a dose quantity at the treatment sites, whilst ensuring that this quantity does not exceed a specified threshold at other field locations, particularly on the surface of the ribs. Previously, a boundary element approach based on a Generalised Minimal Residual (GMRES) implementation of the Burton-Miller formulation was developed to predict the field of a multi-element HIFU array scattered by human ribs, the topology of which was obtained from CT scan data [1].

    Default pediatric protocols on many digital radiography systems are configured based on patient age. However, age does not adequately characterize patient size, which is the principal determinant of proper imaging technique. Use of default pediatric protocols by inexperienced technologists can result in patient overexposure, inadequate image quality, or repeated examinations. To ensure diagnostic image quality at a well-managed patient radiation exposure by transitioning to thickness-based protocols for pediatric portable abdomen radiography. We aggregated patient thickness data, milliamperes (mAs), kilovoltage peak (kVp), exposure index (EI), source-to-detector distance, and grid use for all portable abdomen radiographs performed in our pediatric hospital in a database with a combination of automated and manual data collection techniques. We then analyzed the database and used it as the basis to construct thickness-based protocols with consistent image quality across varying patient thicknesses, as determined by the EI. Retrospective analysis of pediatric portable exams performed at our adult-focused hospitals demonstrated substantial variability in EI relative to our pediatric hospital. Data collection at our pediatric hospital over 4 months accumulated roughly 800 portable abdomen exams, which we used to develop a thickness-based technique chart. Through automated retrieval of data in our systems' digital radiography exposure logs and recording of patient abdomen thickness, we successfully developed thickness-based techniques for portable abdomen radiography.

    2013-03-01

    Acute abdomen can be defined as a medical emergency in which there is sudden and severe pain in abdomen with accompanying signs and symptoms that focus on an abdominal involvement. It accounts for about 8 % of all children attending the emergency department. The goal of emergency management is to identify and treat any life-threatening medical or surgical disease condition and relief from pain. In mild cases often the cause is gastritis or gastroenteritis, colic, constipation, pharyngo-tonsilitis, viral syndromes or acute febrile illnesses. The common surgical causes are malrotation and Volvulus (in early infancy), intussusception, acute appendicitis, and typhoid and ischemic enteritis with perforation. Lower lobe pneumonia, diabetic ketoacidosis and acute porphyria should be considered in patients with moderate-severe pain with little localizing findings in abdomen. The approach to management in ED should include, in order of priority, a rapid cardiopulmonary assessment to ensure hemodynamic stability, focused history and examination, surgical consult and radiologic examination to exclude life threatening surgical conditions, pain relief and specific diagnosis. In a sick patient the initial steps include rapid IV access and normal saline 20 ml/kg (in the presence of shock/hypovolemia), adequate analgesia, nothing per oral/IV fluids, Ryle's tube aspiration and surgical consultation. An ultrasound abdomen is the first investigation in almost all cases with moderate and severe pain with localizing abdominal findings. In patients with significant abdominal trauma or features of pancreatitis, a Contrast enhanced computerized tomography (CECT) abdomen will be a better initial modality. Continuous monitoring and repeated physical examinations should be done in all cases. Specific management varies according to the specific etiology.

    Barium appendicitis (BA) is a rarely seen entity with fewer than 30 reports in the literature. However, it is a known complication of barium imaging. To report a case of BA in a patient whose computed tomography (CT) scan was initially read as foreign body ingestion. An 18-year-old man presented with right lower quadrant pain after upper gastrointestinal imaging 2 weeks prior. A CT scan was obtained of his abdomen and pelvis that revealed a finding that was interpreted as a foreign body at the area of the terminal ileum. A plain X-ray study of the abdomen revealed radiopaque appendicoliths. Pathology confirmed the diagnosis of barium appendicitis. BA is a rare entity and the pathogenesis is unclear. Shorter intervals between barium study and presentation with appendicitis usually correlate with fewer complications. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    INTRODUCTION To present the management of open abdomen with colorectal fistula by application of intrarectal negative pressure system (NPS) in addition to abdominal NPS. PRESENTATION OF CASE Twenty-year old man had a history of injuries by a close-range gunshot to the abdomen eight days ago and he had been treated by bowel repairs, resections, jejunal anastomosis and Hartman's procedure. He was referred to our center after deterioration, evisceration with open abdomen and enteric fistula in septic shock. There were edematous, fibrinous bowels and large multiple fistulas from the edematous rectal stump. APACHE II, Mannheim Peritoneal Index and Björck scores were 18, 33 and 3, respectively (expected mortality 100%). After intensive care for 5 days, he was treated by abdominal and intrarectal NPS. NPS repeated for 5 times and the fistula was recovered on day 18 completely. Fascial closure was facilitated with a dynamic abdominal closure system (ABRA) and he was discharged on day 33 uneventfully. There was no herniation and any other problem after 12 months follow-up. DISCUSSION Management of fistula in OA can be extremely challenging. Floating stoma, fistula VAC, nipple VAC, ring and silo VAC, fistula intubation systems are used for isolation of the enteric effluent from OA. Several biologic dressings such as acellular dermal matrix, pedicled flaps have been used to seal the fistula opening with various success. Resection of the involved enteric loop and a new anastomosis of the intestine is very hard and rarely possible. In all of these reports, usually patients are left to heal with a giant hernia. In contrast to this, there is no hernia in our case during one year follow up period. CONCLUSION Combination of intra and extra luminal negative pressure systems and ABRA is a safe and successful method to manage open abdomen with colorectal fistula. PMID:24584042

He was referred to our center after deterioration, evisceration with open abdomen and enteric fistula in septic shock. There were edematous, fibrinous bowels and large multiple fistulas from the edematous rectal stump. APACHE II, Mannheim Peritoneal Index and Björck scores were 18, 33 and 3, respectively (expected mortality 100%). After intensive care for 5 days, he was treated by abdominal and intrarectal NPS. NPS repeated for 5 times and the fistula was recovered on day 18 completely. Fascial closure was facilitated with a dynamic abdominal closure system (ABRA) and he was discharged on day 33 uneventfully. There was no herniation and any other problem after 12 months follow-up. Management of fistula in OA can be extremely challenging. Floating stoma, fistula VAC, nipple VAC, ring and silo VAC, fistula intubation systems are used for isolation of the enteric effluent from OA. Several biologic dressings such as acellular dermal matrix, pedicled flaps have been used to seal the fistula opening with various success. Resection of the involved enteric loop and a new anastomosis of the intestine is very hard and rarely possible. In all of these reports, usually patients are left to heal with a giant hernia. In contrast to this, there is no hernia in our case during one year follow up period. Combination of intra and extra luminal negative pressure systems and ABRA is a safe and successful method to manage open abdomen with colorectal fistula. Copyright © 2014 The Authors.

    Full Text Available A 79-year-old female called 911 for abdominal pain in her left upper quadrant with radiation through to her back and left shoulder for three hours. Upon arrival to the emergency department her physical exam was positive only for tenderness in the left upper quadrant of her abdomen. The patient denied any history of trauma but reported she “did sneeze three times” just prior to the onset of her pain. Computed tomography angiography of the abdomen and pelvis was obtained to evaluate for vascular pathology. The radiologist immediately called with concern for splenic laceration. The general surgeon took the patient directly to the operating room where she underwent a splenectomy and recovered without sequelae. This is the first case report of spontaneous splenic rupture that resulted after the act of sneezing. It is important to be aware of this rare clinical entity because early recognition can be life saving.

    Wound dehiscence is a serious postoperative complication, with an incidence of 0.5-3% after primary closure of a laparotomy incision, and represents an acute mechanical failure of wound healing. Relatively recently the concept of "intentional open abdomen" was described and both clinical entities share common pathophysiological and clinical pathways ("postoperative open abdominal wall"). Although early reconstruction is the target, a significant proportion of patients will develop adhesions between abdominal viscera and the anterolateral abdominal wall, a condition widely recognized as "frozen abdomen," where delayed wound closure appears as the only realistic alternative. We report our experience with a patient who presented with frozen abdomen after wound dehiscence due to surgical site infection and application of the "Coliseum technique" for its definitive surgical management. This novel technique represents an innovative alternative to abdominal exploration, for cases of "malignant" frozen abdomen due to peritoneal carcinomatosis. Lifting the edges of the surgical wound upwards and suspending them under traction by threads from a retractor positioned above the abdomen facilitates approach to the peritoneal cavity, optimizes exposure of intra-abdominal organs, and prevents operative injury to the innervation and blood supply of abdominal wall musculature, a crucial step for subsequent hernia repair.

    Wandering spleen is a rare condition which if uncorrected, can result in torsion and infarction. Clinical presentation of a wandering spleen can vary from asymptomatic abdominal mass to acute abdominal pain. Radiological investigations play a pivotal role in diagnosis as the clinical diagnosis is usually impossible. We present a case of wandering spleen with torsion and complete infarction that occurred in a 32-year-old multiparous female. The diagnosis was established preoperatively on colour Doppler and CT of the abdomen with subsequent confirmation on surgery. Wandering spleen is a rare clinical condition which can present as acute abdomen. An increased awareness of this entity together with the timely use of ultrasound and CT of the abdomen can play an important role in preoperative diagnosis and surgical management

    Full Text Available BACKGROUND Abdominal trauma continues to account for a large number of trauma-related injuries and deaths. Motor vehicle accidents and urban violence, respectively, are the leading causes of blunt and penetrating trauma to this area of the body. Unnecessary deaths and complications can be minimized by improved resuscitation, evaluation and treatment. The new techniques and diagnostic tools available are important in the management of abdominal trauma. These improved methods, however, still depend on experience and clinical judgment for application and determination of the best care for the injured patient. The aim of the study is to 1. Analyse the incidence, clinical characteristics, diagnosis, indications for laparotomy, therapeutic methods and morbidity & mortality rates. 2. To study nature of blunt abdominal trauma. 3. To assess patient for surgical intervention and to avoid negative laparotomy. 4. To assess morbidity rate in different organs injury. 5. To evaluate modalities of treatment, complications and prognosis. MATERIALS AND METHODS This study is a prospective study on 97 patients with Blunt injuries to the abdomen admitted in S.V.R.R.G.G. Hospital, Tirupati during October 2013-15. Inclusion Criteria Patients > 13 years, with Blunt injury to abdomen either by RTA, fall, object contact, assault giving written informed consent. Exclusion Criteria Patients <13 yrs. Blunt injuries due to blasts, patients with severe cardiothoracic and head injuries who are hemodynamically unstable. CONCLUSION Blunt Trauma to abdomen is on rise due to excessive use of motor vehicles. It poses a therapeutic and diagnostic dilemma for the attending surgeon due to wide range of clinical manifestations ranging from no early physical findings to progression to shock. So, the Trauma surgeon should rely on his physical findings in association with use of modalities like x-ray abdomen, USG abdomen and abdominal paracentesis. Hollow viscus perforations are

    Abdominal compartment syndrome (ACS) is defined as an increase of intra-abdominal pressure (IAH) to values higher than 20 mmHg, associated with reduced perfusion and organ dysfunction. There is a classification of open abdomen which stratifies patients according to the natural history of improvement or clinical deterioration. The aim of treatment is to maintain the open abdomen at the lowest level and to prevent progression to a more complex level. Surgical treatment essentially consists in abdominal decompression by leaving the abdomen open. Analysis of the literature shows that negative pressure increases the rate of primary fascial closure; entero-cutaneous fistulas are seen in a minority of cases, without seeming consequence of the application of the dressing. Open abdomen management consists of three treatment stages: acute (24-48 hours), intermediate (from 48 hours to 10 days) and late or reconstruction (from 10 days to the final closure). It's important to recognize patients at risk of IAH and the first signs of ACS and intervene early with abdominal decompression if this will establish itself. Management of the open abdomen is now facilitated by negative pressure devices, which positively affect the morbidity and mortality of patients with ACS.

    Acute abdomen during pregnancy is a medico-surgical emergency demanding concerted, synchronized specialties approach of obstetrician, surgeon and gastroenterologist. Duodenal perforation is one of the rarer causes of acute abdomen in pregnancy. Here, we report a case of duodenal perforation with peritonitis in third trimester of pregnancy requiring surgical management. Our aim of reporting this case is to stress the physicians to keep the differential of duodenal perforation also in mind while dealing with cases of acute abdomen in pregnancy and to proceed with multidisciplinary approach for better feto-maternal outcome.

    Full Text Available Abstract Introduction Cardiac metastases are found in six to 20% of autopsies of patients with malignant neoplasm. The most common neoplasms that metastasize to the heart are malignant melanoma, lymphoma, and leukemia, but the relative numbers are greater with breast and lung cancers, reflecting the most common incidence of these cancers. Case presentation A 60-year-old Hispanic man presented to our hospital after being transferred from an outside hospital for workup and evaluation of an adrenal mass of the abdomen and pelvis, found on computed tomography. His chief complaint upon admission was altered mental status. Physical examination was unremarkable. He was alert and oriented and had a dry and non-erythematous oropharynx, and bilateral diffuse wheezing on lung examination. Computed tomography of the chest showed multiple hypodense lesions in the left ventricular myocardium, suggestive of metastases. There were also tiny sub-centimeter nodular densities in the right upper and lower lobes. Adrenal glands contained hypodense lesions, which showed characteristic adenocarcinomatous malignant cells. Conclusion Cancers which have metastasized to the heart are found in six to 20% of patients with malignant neoplasms. The right side of the heart is more commonly involved in metastasis. This study is unusual in that a tumor of an unknown primary origin had metastasized to the left side of the heart.

    Full text: Introduction: Currently MR tomography in comparison with multidetector CT plays a subordinate role in the diagnostic and imaging algorithm in the study of abdomen organs. However, technical innovation occurring in magnetic resonance imaging, allow us to obtain images with high resolution at an acceptable duration of the study. Moreover assessment of the condition of the biliary system can be optimized through the use of MR cysto- pancreatography that allows non-invasive assessment of pancreatic biliary system, and the use of MR angiography, which visualized in the abdominal vessels. What you will learn: methods for approach to patient for abdominal examination; the advantages and disadvantages of different MR sequences in imaging of organs and structures in the abdomen; the advantages and disadvantages of different types MR cysto- pancreatography for the purpose of magnetic resonance tomography in patients with diseases in the abdomen. Discussion: MR is used for diseases of the organs in the abdomen especially for diagnosis and staging of neoplastic processes, to differentiate between tumors and inflammatory processes, and in the characterization of the cystic lesion. MRI scan has three main tasks in the assessment of the conditions of the organs in the abdomen: should provide a definitive diagnosis in patients with inconclusive data on abdominal ultrasound or CT scan for any pathological process , must allow proper staging of malignancies in order to preoperative assessment of the state of patient and sometimes non-resectability of the tumor formations due to their advancing, should characterize cystic lesions whose frequency increases in the conduct of routine or diagnostic CT studies. Conclusion: As a result of rapid technological progress current protocols for MR examinations of the abdomen are very different from those used 10 years ago. Most sequences can be performed during one or more breath-hold cycle and 3D sequences with thin consecutive

    The diagnosis of Delayed Splenic Rupture poses a major challenge to even the most astute clinician, as it can mimic other medical emergencies. We present a case of an unusual presentation of delayed splenic rupture in a 23-year-old Caucasian man, who presented to the emergency department with a 2 day history of left upper quadrant pain. He initially denied any history of trauma. There were no signs of generalized peritonisim on examination but his haemoglobin level was low (8.9 gm\\/dl) for which there was no obvious cause identified. He was resuscitated and a computed tomography of the abdomen was performed. This revealed complete rupture of the splenic capsule with haemorrhagic fluid in the abdomen. With the computed tomography abdomen findings and further questioning of the patient, the only potential precipitating event that he could remember was a minor kick to the left upper quadrant more than 2 weeks ago while playing football. An urgent splenectomy was performed and histology confirmed complete rupture of the splenic capsule with a large adherent haematoma to the capsule. This case illustrates the difficulty in diagnosing delayed splenic rupture especially when accurate history is not available. A high index of suspicion is essential as delay in diagnosis can be fatal. Early diagnosis in suspected cases can be achieved by performing computed tomography of the abdomen.

A 22-year-old Caucasian male presented to the emergency department 4 h following an injury sustained during football training. He complained of the immediate onset of severe left upper quadrant and left flank pain. He subsequently developed frank haematuria. On initial review, he was haemodynamically stable. CT of the abdomen and pelvis showed a grade 4 renal trauma. Over the following 36 h, he remained haemodynamically stable. On serial abdominal examinations however, he developed a rigid abdomen and was noted to have a haemoglobin drop. Interval CT scan showed a progression of his injury and the presence of a haemoperitoneum. An emergency laparotomy was performed resulting in a left nephrectomy. He made an uneventful recovery.

    Introduction: This study tends to test the capacity of the computed tomography in assist in the diagnosis and the approach of the acute abdomen. Material and method: This is a longitudinal and prospective study, in which were analyzed the patients with the diagnosis of acute abdomen. There were obtained 105 cases of acute abdomen and after the application of the exclusions criteria were included 28 patients in the study. Results: Computed tomography changed the diagnostic hypothesis of the physicians in 50% of the cases (p 0.05), where 78.57% of the patients had surgical indication before computed tomography and 67.86% after computed tomography (p = 0.0546). The index of accurate diagnosis of computed tomography, when compared to the anatomopathologic examination and the final diagnosis, was observed in 82.14% of the cases (p = 0.013). When the analysis was done dividing the patients in surgical and nonsurgical group, were obtained an accuracy of 89.28% (p 0.0001). The difference of 7.2 days of hospitalization (p = 0.003) was obtained compared with the mean of the acute abdomen without use the computed tomography. Conclusion: The computed tomography is correlative with the anatomopathology and has great accuracy in the surgical indication, associated with the capacity of increase the confident index of the physicians, reduces the hospitalization time, reduces the number of surgeries and is cost-effective.

    150 MR examinations of the upper abdomen were carried out after the oral administration of 5 ml/kg body weight of a gadolinium DTPA formulation (1.0 mmol/l, 15 g/l manitol), with reference to the delineation of the pancreas, the liver and intra-abdominal fat. For comparison, 100 MR examinations without oral opacification of the G.I. tract were evaluated. Contrast administration resulted in a signal-intensive demonstration of the G.I tract for all measurement sequences. The intraluminal contrast improved the distinction between normal and abnormal structures, T 1 and T 2 sequences and the demonstration of fat on T 2 -weighted series. T 1 -weighted series showed the best diagnostic results. In 25% there was meteorism and diarrhoea within 24 hours of the administration of the oral contrast. (orig.) [de

    Acute abdominal pain is one of the most common causes for referrals to the emergency department. The sudden onset of severe abdominal pain characterising the ''acute abdomen'' requires rapid and accurate identification of a potentially life-threatening abdominal pathology to provide a timely referral to the appropriate physician. While the physical examination and laboratory investigations are often non-specific, computed tomography (CT) has evolved as the first-line imaging modality in patients with an acute abdomen. Because the new multi-detector CT (MDCT) scanner generations provide increased speed, greater volume coverage and thinner slices, the acceptance of CT for abdominal imaging has increased rapidly. The goal of this article is to discuss the role of MDCT in the diagnostic work-up of acute abdominal pain. (orig.)

    Open abdomen therapy may be necessary to prevent or treat abdominal compartment syndrome (ACS). The aim of the study was to analyse the primary delayed fascial closure (PDFC) rate and complications after open abdomen therapy with vacuum and mesh mediated fascial traction (VACM) after aortic repair and to compare outcomes between those treated with open abdomen after primary versus secondary operation. This was a retrospective cohort, multicentre study in Sweden, Finland, and Norway, including consecutive patients treated with open abdomen and VACM after aortic repair at six vascular centres in 2006-2015. The primary endpoint was PDFC rate. Among 191 patients, 155 were men. The median age was 71 years (IQR 66-76). Ruptured abdominal aortic aneurysm (RAAA) occurred in 69.1%. Endovascular/hybrid and open repairs were performed in 49 and 142 patients, respectively. The indications for open abdomen were inability to close the abdomen (62%) at primary operation and ACS (80%) at secondary operation. Duration of open abdomen was 11 days (IQR 7-16) in 157 patients alive at open abdomen termination. The PDFC rate was 91.8%. Open abdomen initiated at primary (N=103), compared with secondary operation (N=88), was associated with less severe initial open abdomen status (p=.006), less intestinal ischaemia (p=.002), shorter duration of open abdomen (p=.007), and less renal replacement therapy (RRT, popen abdomen initiated at primary versus secondary operation. VACM was associated with a high PDFC rate after prolonged open abdomen therapy following aortic repair. Patient outcomes seemed better when open abdomen was initiated at primary, compared with secondary operation but a selection effect is possible.

    Full Text Available Cardiac myxomas are the most common benign tumors found in the heart. They usually appear in the left atrium. Those originating from the left ventricle (LV are rare. Although clinical presentation may vary, dyspnea and embolism are the most commonly reported symptoms. In the present case study, a 27-year-old woman with a large myxoma originating from the left ventricular free wall is studied. She had atypical complaints, mainly epigastric discomfort, nausea, vomiting, and anorexia. She was hospitalized for acute abdomen, but subsequent investigations revealed a large myxoma that fully filled the LV and severely compromised the flow of the aortic and mitral valves. After successful emergency tumor resection, all symptoms disappeared. The uncommon presentation caused by these tumors is discussed in this study.

    Butterfly's forward flight with periodic flapping motion is longitudinally unstable, and control of the thoracic pitching angle is essential to stabilize the flight. This study aims to comprehend roles which the abdominal motion play in the pitching stability of butterfly's flapping flight by using a two-dimensional model. The control of the thoracic pitching angle by the abdominal motion is an underactuated problem because of the limit on the abdominal angle. The control input of the thorax-abdomen joint torque is obtained by the hierarchical sliding mode control in this study. Numerical simulations reveal that the control by the abdominal motion provides short-term pitching stabilization in the butterfly's flight. Moreover, the control input due to a large thorax-abdomen joint torque can counteract a quite large perturbation, and can return the pitching attitude to the periodic trajectory with a short recovery time. These observations are consistent with biologists' view that living butterflies use their abdomens as rudders. On the other hand, the abdominal control mostly fails in long-term pitching stabilization, because it cannot directly alter the aerodynamic forces. The control for the long-term pitching stabilization will also be discussed.

    Conclusion: The etiology of acute abdomen varied depending on the age of the patient. Acute appendicitis was the most common cause of acute abdomen in children older than 1 year of age, followed by traumatic injury. Abdominal CT scanning was a useful diagnostic imaging modality in patients with both traumatic and non-traumatic abdominal pain.

    White rats-males were used in experiments. Irradiation dose of abdomen area is 13.5 Gy (1400 R). Parenteral nutrition using aminoacid preparation of polyamine affects favourably during radiation damage resulted from local irradiation of abdomen area. This was manifested in weakening of gastroenteric syndrom, reduction of 3.5 day death of animals and increase of their 30 day survival rate, intensification of recovery processes in small intestine, decrease of cell devastation in bone marrow

    The obstetrician often has a difficult task in diagnosing and managing the acute abdomen in pregnancy. A reluctance to operate during pregnancy adds unnecessary delay, which may increase morbidity for both mother and fetus. In this study, we present our experience in pregnant patients with acute abdomen. Pregnant patients with acute abdomen requiring surgical exploration were enrolled from 2007 to 2010. Demographics, gestational age, symptoms, fetal loss, preterm delivery, imaging studies, operative results, postoperative complications and histopathologic evaluations were recorded. Ultrasound (US) and magnetic resonance (MR) imaging studies were evaluated. Data analyses were performed with Microsoft Excel and statistical evaluations were done by using Student's t-test. There were 20 patients with a mean age of 32 years. The rate of emergency surgery was seen to be significantly higher in the second trimester (pacute abdomen (30% and 15%, respectively). All patients tolerated surgery well, and postoperative complications included wound infection, 10%, preterm labor, 5%, and prolonged paralytic ileus, 5%. One patient died from advanced gastric carcinoma and the only fetal death was seen in this case. Prompt diagnosis and appropriate therapy are crucial in pregnant with acute abdomen. The use of US may be limited and CT is not desirable due to fetal irradiation. MR has thus become increasingly popular in the evaluation of such patients. Adhesive small bowel obstruction should be kept in mind as an important etiology. Copyright © 2011. Published by Elsevier Ireland Ltd.

    To obtain the characteristic sonographic findings of ovarian hemorrhage and investigate the usefulness of ultrasonography in the diagnosis. Forty-nine cases presenting acute abdomen diagnosed as ovarian hemorrhage by ultrasonography or surgicopathological confirmation. We observed the size and margin of the ovary, size, pattern, shape, wall and internal echogenecity of the masses and the amount of hemoperitoneum. We also performed a color Doppler study to evaluate the blood flow pattern and resistive index (RI). The age of patients were between 21-41. Most symptoms occurred from days 14 to 30 of her menstrual cycle and were presented for less than 24 hours. Twenty patients had a history of intercourse shortly before the onset of the symptom. Thirty two cases involved the right ovary while the other 17 cases involved the left. All patients had a negative urine or serum hCG test except for 4 pregnant women. The size of the ovary was measured as mean 5.1 cm and marginal irregularly was noted in 36 cases. Mixed echoic solid masses were observed in 6 cases and variable echogenecity of cystic masses were seen in 43 cases. Maximal diameter of adnexal masses were measured as mean 3.95 cm. Internal echogenecity of cystic masses appeared as mainly heterogeneous (21). Twenty two cystic masses had a thick irregular wall and 17 had a thin smooth wall. Hypoechoic rim like halo surrounding was noted in 17 cystic masses. 17 cases seemed to have a small amount of hemoperitoneum, a moderate amount in 22 cases and a large amount in 9 cases. The blood flow pattern of cystic masses showed a rim (29) and spotty (8) pattern in the color Doppler study. Measured RI was 0.41 (mean). Fertile women with the complaint of acute abdominal pain, who has the laboratory data of negative hCG test, ultrasonographic findings of enlargement of ovary with irregular margin, heterogeneous echoic cystic mass, peripheral halo surrounding the mass, hemoperitoneum and low resistance index of peripheral blood

    We evaluated the usefulness of computed tomography (CT) in diagnosing and managing acute abdomen. Subjects were 91 patients admitted complaining of acute abdominal pain and divided into two groups-those undergoing CT within 24 hours of admission (emergency CT group, n=70), those without CT (Non-CT group, n=21). The emergency CT group was subdivided into those with bowel obstruction (bowel obstruction group, n=29), those with acute appendicitis and other diseases necessitating differential diagnosis (appendicitis group, n=36), those with perforation of the digestive tract (perforation group, n=4), and other disease (n=1). We evaluated the accuracy of admission diagnosis retrospectively in each group. The final diagnosis of the bowel obstruction group was adhesive bowel obstruction in 16, colon cancer in 5, external hernia in 3 and other in 5. That in the appendicitis group was acute appendicitis in 25, colonic diverticulitis in 3, pelvic inflammatory disease in 3, ovarian hemorrhage in 2 and other in 5. The origin of perforation in the perforation group was upper digestive tract in 2 and lower digestive tract in 2. The sensitivity, specificity and accuracy of admission diagnosis in the emergency CT group was 91.1, 100 and 91.4%, respectively. The accuracy of admission diagnosis was 96.5% in the bowel obstruction group, 88.9% in the appendicitis group and 75.9% in the perforation group. Patients who could not be diagnosed precisely consisted of 6 patients in the emergency CT group. Those who could not be diagnosed precisely included 3 with pericecal abscess, 1 with acute appendicitis, 1 with stercoral perforation of the sigmoid colon and 1 with impacted bezoar in the small intestine. Evaluated retrospectively, 4 patients were able to be diagnosed by CT on admission. In diagnosis of acute abdomen, CT was useful in differential diagnosis of bowel obstruction and acute appendicitis, detection of fine free air, and determine of perforated sites. Emergency CT was thus

    Acute coagulopathy with exsanguinating bleeding occurs in 2-5% of all trauma cases carrying mortality rate near 100% after conventional management. In the last few decades, the development of damage control surgery (DCS) in combination with the technique of open abdomen led to significantly improved survival among these patients. A descriptive study based on a retrospective analysis of 12 consecutive blast victims with exsanguinating bleeding underwent DCS and open abdomen management. All patients were soldiers injured during their deployment in Iraq and Afghanistan during 2002-2007, treated by our deployed surgical teams. Vacuum Assisted Closure (V.A.C., KCI) and vacuum pack (VP) was used for a temporary closure of abdomen. A cumulative analysis of all relevant series used these methods during the period 2000-2013 was performed. DCS was applied in 12 of 114 consecutive blast victims (10.5%) with survival rate 66.7% (8/12). Eleven had open abdomen with temporary closure with V.A.C. in 6 and VP in 5. Four patients died before the definitive closure (36.4%). The survivors (n = 8) were with a mean age 28.5 years, suffered from a critical trauma with a mean Injury Severity Score 35.5. V.A.C was used in 4 of them, VP in 3. Primary closure of abdomen was achieved in 6 (85.7%) within 3.5 days and mean 1.3 dressing changes. Due to ACS, the abdomen was closed through skin suture only and a creation of planned ventral hernia in 1 patient treated with VP (1/7, 14.3%). Wound infection was observed in 1 case (14.3%). Despite the small sample size, our series clearly demonstrate the benefits of DCS and open abdomen in trauma patients with exsangiunating bleeding. The survival rate is highly dependent on the rapid implementation of DCS in properly selected patients. V.A.C. and VP provide a high rate of primary fascial closure in trauma.

    The feasibility of extending the VATS approach to locally advanced NSCLC has been described with good clinical outcome. These complex resections are still technically challenging and patient safety must remain the highest priority. In this article, we describe our routine VATS approach for left upper lobectomy in proximal, locally advanced lesions. Both surgical and anaesthesiology teams are trained during simulation sessions to respond rapidly in case of urgent thoracotomy. Encircling arterial and venous vessels allow control of inadvertent bleeding during difficult dissection. Also, whenever needed the double vessel control technique is a time saver waiting for conversion to thoracotomy.

    Jejunal diverticulosis is a rare, usually asymptomatic disease. Its incidence increases with age. If symptomatic, diverticulosis may cause life-threatening acute complications such as diverticulitis, perforation, intestinal hemorrhage and obstruction. In this report, we aimed to present a 67-year-old male patient with jejunal diverticulitis accompanying with abdominal pain and vomiting. A 67-year-old male patient complaining of epigastric pain for a week and nausea and fever for a day presented to our emergency department. Ultrasonographic examination in our clinic revealed diverticulum-like images with thickened walls adjacent to the small intestine loops, and increase in the echogenicity of the surrounding mesenteric fat tissue. Contrast-enhanced abdominal computed tomography showed multiple diverticula, thickened walls with showing contrast enhancement and adjacent jejunum in the left middle quadrant, increased density of the surrounding mesenteric fat tissue, and mesenteric lymph nodes. The patient was hospitalized by general surgery department with the diagnosis of jejunal diverticulitis. Conservative intravenous fluid administration and antibiotic therapy were initiated. Clinical symptoms regressed and the patient was discharged from hospital after 2 weeks. In cases of diverticulitis it should be kept in mind that in patients with advanced age and pain in the left quadrant of the abdomen, diverticular disease causing mortality and morbidity does not always originate from the colon but might also originate from the jejunum

    A previously healthy 3-year-old boy presented to the emergency department with abdominal pain, fever, and emesis. Laboratory and radiologic evaluation for causes of acute abdomen were negative; however, review of the abdominal x-ray demonstrated cardiomegaly with the subsequent diagnosis of pericardial cyst by echocardiogram and computed tomography. The patient underwent surgical decompression and attempted removal of the cystic structure revealing that the cyst originated from the epicardium. His abdominal pain and fever resolved postoperatively and he completed a 3-week course of ceftriaxone for treatment of Propionibacterium acnes infected congenital epicardial cyst. Emergency department physicians must maintain a broad differential in patients with symptoms of acute abdomen to prevent complications from serious cardiac or pulmonary diseases that present with symptoms of referred abdominal pain.

    A 43-year-old woman of Ghanaian origin presented with severe upper abdominal pain starting on a long distance flight. Physical examination revealed tenderness on palpation in the left upper abdomen and flank. There was no report of pre-existing conditions or permanent medication in the medical history. Laboratory tests showed signs of haemolytic anemia and elevated inflammatory parameters. The "thick blood smear" was normal. Ultrasonography revealed an enlarged spleen (14×5 cm) with inhomogeneous parenchyma and vast, diffusely spread hypoechoic lesions in perihilar location, interpreted as extended splenic infarction. Symptom onset on a long distance flight, haemolytic anemia and extended splenic infarction led to the assumption of a vasoocclusive crisis with haemolysis. Moleculargenetic tests proved the presence of HbSC-sickle cell disease and heterozygous alpha-thalassemia. After infusion of crystalloid solution the patient was asymptomatic further on. Due to splenic infarction she received prophylactic treatment with Cefuroxim. A vaccination against pneumococci, meningococci and Haemophilus influenza B was recommended. Mild hypoxia and dehydration on a long distance flight can trigger a sickle cell crisis and may contribute to late clinical manifestation and diagnosis of sickle cell disease in some cases. Patients suffering from HbSC-sickle cell disease are at risk for the same life-threatening complications as patients with HbSS-sickle cell disease. HbSC-sickle cell disease should not be considered as a mild form of HbSS-sickle cell disease but as a separate disease with specific clinical manifestations. In contrast-enhanced ultrasonography, splenic infarction due to sickle cell crisis may markedly differ from "typical" arterial thromboembolic infarction. © Georg Thieme Verlag KG Stuttgart · New York.

    A 70-year-old man with a 3-year history of bronchiectasis presented with massive hemoptysis that had lasted for 3 days. In our attempt to perform bronchial artery embolization, upper abdominal angiography was required to locate the left bronchial artery, which in this case was of anomalous origin, arising from a replaced left hepatic artery, which arose from the left gastric artery-a very unusual anatomical variant. We performed embolization with polyvinyl alcohol particles, and the patient's symptoms resolved completely, with no additional complications after conservative treatment.

    We report the case of a 24-year-old female after sustaining a shotgun wound in the left upper extremity and chest. Initial emergency diagnostics revealed numerous shotgun pellets scattered throughout the left-side soft tissue, chest and upper lung lobe with one pellet having migrated into the left ventricle of the heart.Due to the devastating injury pattern, gunshot wounds are interdisciplinarily challenging and should include extended initial diagnostics, such as contrast agent CT. The potential toxicity of elevated lead blood levels have to be taken into further account.

    Postoperative tetralogy of Fallot (TOF) patients often develop progressive aortic root dilatation due to an impairment in aortic elastic properties. (1) to assess aortic elasticity at the level of the aortic upper wall by tissue Doppler imaging (TDI); (2) to evaluate the influence of aortic elasticity on left ventricular (LV) diastolic function in TOF patients. Twenty-eight postoperative TOF patients (14 males, 14 females. Mean age: 25.7 ± 1.6 years) and 28 age- and sex-matched normal subjects were examined. Aortic distensibility and stiffness index were calculated. Aortic wall systolic and diastolic velocities, LV systolic and diastolic parameters were assessed by TDI. Aortic distensibility was significantly lower (P = .024), and aortic stiffness index significantly higher (P = .036) in TOF patients compared to controls. E/E' was significantly higher in TOF than in control group (P < .001). Aortic upper wall early diastolic velocity (AWEDV) was significantly correlated with aortic stiffness index (r: -0.42; P < .03), aortic distensibility (r = 0.54; P < .004), left atrial volume (r = -0.62; P = .0004), and E/E' ratio (r = -0.87; P < .0001). The latter relationship remained significant even when excluding the influence of age at surgery (r = -0.60; P < .0007) and of previous palliative surgery (r = -0.53; P < .02). Aortic elastic properties can be directly assessed using TDI to measure AWEDV. Aortic elasticity is significantly lower in postoperative TOF patients, exerting a negative effect also on LV diastolic function, with a potential long-term influence on clinical status. © 2016 Wiley Periodicals, Inc.

    1992-08-01

    Using a laser Doppler velocimeter (LDV) subcutaneous adipose tissue blood flow (AF) was recorded in the upright and supine positions in the upper and lower abdomen in 22 morbidly obese patients before gastroplasty. Age was 42 +/- 3 (mean +/- SEM), weight 135 +/- 7 kg, and body mass index (BMI) 51 +/- 3. Adipose flow expressed as mV was: supine, upper abdomen 647 +/- 23, lower abdomen 604 +/- 24; upright, upper abdomen 621 +/- 27, lower abdomen 607 +/- 29. AF was significantly more in the upper than lower abdomen (supine position) and AF was significantly lower in the lower abdomen upright than the upper abdomen supine. Regression analysis of age indicates that blood flow decreases in the lower abdomen so that in the supine position the difference between upper and lower abdomen AF increases. Similar analysis of BMI did not indicate significant trends. These data indicate that with morbid obesity there is lower tissue blood flow to the lower abdomen. This may explain why such patients may develop areas of painful ischemic necrosis in the dependent region of their anterior abdominal pannus.

    Full Text Available Background: Acute abdomen in children has been aptly described as Pandora′s box. Unlike computerized tomography (CT scan, ultrasonography (USG has no radiation hazard and the present study analyses the diagnostic yield of the USG in acute abdomen in children. Materials and Methods: Between September 2001 to October 2003, 75 patients with acute abdomen underwent clinical examination, routine biochemical tests, erect X-ray abdomen, USG and CT scan. Laparotomy and histological examination established final diagnosis. Results: The accuracy of correct diagnosis was 60%, 66.6%, 64%, 98.7% with clinical examination alone, USG alone, clinical examination combined with conventional radiography, and clinical evaluation combined with conventional radiography and USG respectively. USG helped to prevent unnecessary laparotomy in 16.3% of patients. Conclusions: USG is good investigative modality in the management of acute abdomen in children.

    2003-01-01

    Background and Purpose: Locoregional relapse is a problem frequently encountered with advanced gastric cancer. Data from the randomized Intergroup trial 116 suggest effectiveness of adjuvant radiochemotherapy, albeit with significant toxicity. The potential of intensity-modulated radiotherapy (IMRT) to reduce toxicity by significantly reducing maximum and median doses to organs at risk while still applying sufficient dose to the target volume in the upper abdomen was studied. Patient and Methods: For a typical configuration of target volumes and organs, a step-and-shoot IMRT plan (eight beam orientations), developed as a class solution for treatment of tumors in the upper abdomen (Figures 1 to 3), a conventional plan, a combination of the conventional plan with a kidney-sparing boost plan, and a conventional plan with noncoplanar ap and pa fields for improved kidney sparing were compared with respect to coverage of target volume and dose to organs at risk with a dose of 45 Gy delivered as the median dose to the target volume. Results: When using the conventional three-dimensionally planned box techniques, the right kidney could be kept below tolerance, but median dose to the left kidney amounted to between 14.8 and 26.9 Gy, depending on the plan. IMRT reduced the median dose to the left kidney to 10.5 Gy, while still keeping the dose to the right kidney 90% of prescription dose were delivered to > 90% of target volume with IMRT (Table 1). Conclusion: IMRT has the potential to deliver efficient doses to target volumes in the upper abdomen, while delivering dose to organs at risk in a more advantageous fashion than a conventional technique. For clinical implementation, the possibility of extensive organ motion in the upper abdomen has to be taken into account for treatment planning and patient positioning. The multitude of potential risks related to its application has to be the subject of thorough follow-up and further studies. (orig.)

    Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup. Appendicitis and complicated biliary pathology are the most frequent causes of non-obstetric acute abdomen in the pregnant patient. The decision to operate, the timing, and the surgical approach are essential for a correct management of this pathology. The aim of this paper is to perform a review and update on the diagnosis and treatment of non-obstetric acute abdomen in pregnancy. Copyright © 2015 AEC. Publicado por Elsevier España, S.L.U.

    A 60-year-old lady with a history of Dukes B2 (T3N0M0) colorectal cancer presented some 2 years following a laparoscopic left hemicolectomy with a 4-day history of absolute constipation. A plain radiograph demonstrated large bowel obstruction, and subsequent CT of the abdomen showed the level of the obstruction to be at the rectum. Initially the aetiology was believed to be recurrence at the site of the anastomosis; however, subsequent review of the imaging and indeed endoscopic examination of the rectum showed it to be volvulus. This was initially treated with endoscopic decompression and later by the insertion of a flatus tube to good effect. The patient was discharged 3 days later with no recurrence of her symptoms at 2 months. PMID:23608861

    Computed tomography (CT) is a non-invasive method of image production that imparts significant doses to a patient, it is expected that pediatric CT examinations will increase the risk of induced cancer in children. In this study the effective doses in a five year-old child submitted to chest or abdomen CT scans were assessed for comparison purposes. The CTEXPO computed program was used with data from routine protocols of a 0 to 13 year-old children in two public hospitals in Belo Horizonte. Hospital A used a Siemens Dual-Slice unit with 80 kV, 41 mA and pitch 2 for chest or abdomen; hospital B used a Multislice GE unit with 120 kV, 45 mA and pitch 1 for chest and 120 kV, 55 mA. and pitch 1 for abdomen. Results of effective doses in a five year-old child were 1.7 and 1.0 mSv in hospital A and 9.1 and 7.2 mSv in hospital B, for chest and abdomen, respectively. Results were compared to the reference effective doses of 7.2 and 5.0 mSv for chest and abdomen respectively that were derived from the air kerma length product values given in ICRP publication 87. Results of hospital A showed that low dose exposures also can be achieved in CT scans of children. Results showed that even a hospital with a modern facility (hospital B) can provided doses higher than reference values if protocols are not adjusted for children. Preliminary results suggested that there is a room for optimizing children exposure submitted to CT scans. (author)

    Patients with an acute abdomen present with marked deterioration in physiological and pathophysiological conditions, which make general anesthesia to a challenging but also potentially dangerous procedure. A broad and fundamental knowledge of the pathophysiologically involved mechanisms of cardiovascular functions during anesthesia and appropriate anesthesiological approach are crucial for a successful peri-operative management. The anesthesiologist's goal is to perform adequate anesthesia while maintaining cardiovascular stability. Monitoring and management of acid-base-status as well as cardiovascular functions are required to maintain sufficient tissue oxygenation during anesthesia. The postoperative anesthesiological management may also crucially influence the further course and therefore should be considered in the anesthesiological planning. Finally, adequate pain management in all these patients is an important and not to underestimate part in the treatment. This article gives an overview on the major aspects in the different fields in the anesthesiological management of patients with an acute abdomen.

    2010-01-01

    The management of polytraumatized patients has been important to know the scope and limitations of ultrasonography resources. A literature review was performed on FAST ultrasound in closed trauma in the abdomen. FAST (focused assessment with sonography for trauma) has been a study performed on the patient who has suffered both abdominal and thoracic trauma to determine the presence or absence of free fluid in these body cavities. The use is directed to locate intraabdominal drugs that may lead to bleeding and endanger the patient's life. Different techniques existent are recommended to use the original FAST as has been the extended FAST. In the United States the three diagnostic techniques generally have been: diagnostic peritoneal lavage, computed tomography (CT) of the abdomen and ultrasonography for the evaluation of patients with trauma abdominal; each of them have had their own advantages and disadvantages to study [es

    Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding.

    Heparin-induced thrombocytopenia (HIT) is a serious adverse effect of heparin administration. This must not be rarely encountered but is not often reported in Japan compared to Western countries. A 68-year-old woman underwent left upper lobectomy for lung cancer. Low-dose unfractionated heparin was administrated to prevent thromboembolism after the operation. Two days later, sudden dyspnea appeared and ultracardiosonography showing an extensive thromboembolus from the main trunk to both main branches of pulmonary artery indicated pulmonary embolization. After the establishment of percutaneous cardiopulmonary support (PCPS) support, the embolus was removed by emergent open heart surgery. However, despite further unfractionated heparin administration following embolization surgery, other thrombus was identified in both the bi-lateral internal jagular veins and inferior vena cava by ultrasonography and contrast computed tomography( CT). Her platelet count was decreased gradually despite platelet transfusion. Plate factor 4( PF4) antibody against heparin in her blood examination was found, and HIT II was diagnosed. Discontinuation of unfractionated heparin and administration of antithrombin agent improved platelet count, and no additional embolization was identified.

    In abdomen computed tomography (CT), repeated radiation exposures are often inevitable for cancer patients who receive surgery or radiotherapy guided by CT images. Low-dose scans should thus be considered in order to avoid the harm of accumulative x-ray radiation. This work is aimed at improving abdomen tumor CT images from low-dose scans by using a fast dictionary learning (DL) based processing. Stemming from sparse representation theory, the proposed patch-based DL approach allows effective suppression of both mottled noise and streak artifacts. The experiments carried out on clinical data show that the proposed method brings encouraging improvements in abdomen low-dose CT images with tumors. (paper)

    The obstructive acute abdomen is a common presentation, for which safe and effective management depends on a fast and accurate diagnosis. Conventional radiograph remains the first choice among the imaging exams because of its availability, low cost and the possibility to be done serially to follow the patient's clinical progression. The ultrasonography does not require ionizing radiation. It is a dynamic and in realtime exam. Computed tomography is used increasingly due to the provision of essential diagnostic information not apparent from radiographs, such as the confirmation of the obstruction, degree and place of the occlusion, presence of ischemia as well as the causes of the obstruction. Magnetic resonance imaging has presented great technological advances and it may play a role in the future of obstructive acute abdomen diagnosis. The objective of this pictorial essay is to review the different imaging techniques used on diagnosing obstructive acute abdomen. (author)

  20. Nineth Rib Syndrome after 10(th) Rib Resection.

    2016-07-01

    The 12(th) rib syndrome is a disease that causes pain between the upper abdomen and the lower chest. It is assumed that the impinging on the nerves between the ribs causes pain in the lower chest, upper abdomen, and flank. A 74-year-old female patient visited a pain clinic complaining of pain in her back, and left chest wall at a 7 on the 0-10 Numeric Rating scale (NRS). She had a lateral fixation at T12-L2, 6 years earlier. After the operation, she had multiple osteoporotic compression fractures. When the spine was bent, the patient complained about a sharp pain in the left mid-axillary line and radiating pain toward the abdomen. On physical examination, the 10(th) rib was not felt, and an image of the rib-cage confirmed that the left 10(th) rib was severed. When applying pressure from the legs to the 9(th) rib of the patient, pain was reproduced. Therefore, the patient was diagnosed with 9(th) rib syndrome, and ultrasound-guided 9(th) and 10(th) intercostal nerve blocks were performed around the tips of the severed 10(th) rib. In addition, local anesthetics with triamcinolone were administered into the muscles beneath the 9(th) rib at the point of the greatest tenderness. The patient's pain was reduced to NRS 2 point. In this case, it is suspected that the patient had a partial resection of the left 10(th) rib in the past, and subsequent compression fractures at T8 and T9 led to the deformation of the rib cage, causing the tip of the remaining 10(th) rib to impinge on the 9(th) intercostal nerves, causing pain.

  2. US anatomy of the great peritoneal cavity and its recesses

    The peritoneum of the great abdominal cavity and its recesses are a blind radiographical area which can however be easily outlined by US when it contains fluid. The anatomical study of these usually virtual cavities represent the purpose of this paper. The natural contrast of the peritoneal fluid as amplified by the mechanical effect produced by an adequate amount of fluid, allows a clear visualization of the anatomy of various peritoneal structures in either upper (subphrenic, subhepatic, lesser sac, etc.) or lower (pelvic) areas. The sovramesocolic and the infracolic compartments are in comunication through the two external paracolic gutters which are the main passageways for the fluids between upper and lower compartments. In fact, peritoneal fluids are in constant movement due to different factors, such as gravity, statics, which causes the peritoneal fluids to flow into the lowest part of the peritoneal cavity, and hydrostatic pressure. Pressure differences are thought to convey fluids from various sites of the abdomen into different areas. In the lower abdomen, pressure is 3 times as much as in the upper abdomen, which causes the fluids to move into the subhepatic and subphrenic regions. The redistribution of fluids can be influenced by particular anatomical causes. The phrenicocolic ligament, e.g., is a barrier to the advancing of fluds along the left paracolic gutter, which makes the right paracolic gutter the main passageway for the fluids. This pattern explains why abscesses are more frequent in the right than in the upper left abdominal regions. Another example in the tiny Winslow opening, which does not allow inflammatory material to pass into the lesser sac in case of inflammatory processes of the great peritoneal cavity and viceversa. Moreover, pointing out fluid collections and abscesses is important, since an early diagnosis and a topografic map are essential order to plan treatment

    Currently, three-dimensional finite element models of the human body have been developed for frequently injured anatomical regions such as the brain, chest, extremities and pelvis. While a few models of the human body include the abdomen, these models have tended to oversimplify the complexity of the abdominal region. As the first step in understanding abdominal injuries via numerical methods, a 3D finite element model of a 50(th) percentile male human abdomen (WSUHAM) has been developed and validated against experimental data obtained from two sets of side impact tests and a series of frontal impact tests. The model includes a detailed representation of the liver, spleen, kidneys, spine, skin and major blood vessels. Hollow organs, such as the esophagus, stomach, small and large intestines, gallbladder, bile ducts, ureters, rectum and adrenal glands are grouped into three bodybags in order to provide realistic inertial properties and to maintain the position of the solid organs in their appropriate locations. Using direct connections, the model was joined superiorly to a partial model of the human thorax, and inferiorly to models of the human pelvis and the lower extremities that have been previously developed. Material properties for various tissues of the abdomen were derived from the literature. Data obtained in a series of cadaveric pendulum impact tests conducted at Wayne State University (WSU), a series of lateral drop tests conducted at Association Peugeot-Renault (APR) and a series of cadaveric lower abdomen frontal impact tests conducted at WSU were used to validate the model. Results predicted by the model match these experimental data for various impact speeds, impactor masses and drop heights. Further study is still needed in order to fully validate WSUHAM before it can be used to assess various impact loading conditions associated with vehicular crashes.

    To assess the relative bioavailability of a new subcutaneous (SC) diclofenac hydroxypropyl b-cyclodextrin (HPbCD) formulation administered to three body sites: quadriceps, gluteus, and abdomen. This was a pilot, single-dose, randomized, three-way crossover relative bioavailability study. A total of 12 healthy subjects received a single SC injection of diclofenac HPbCD 50 mg/1 mL in the quadriceps, gluteus, or abdomen. The AUC was comparable after SC diclofenac HPbCD in the quadriceps, gluteus, and abdomen. The Cmax was comparable after SC administration in the quadriceps or abdomen, and ~ 17% higher in the gluteus. The absorption was rapid (30 minutes) after administration of the treatment at any site. The treatment was well tolerated. The relative bioavailability of SC diclofenac HPbCD was comparable when administered to the quadriceps, gluteus, and abdomen. The new diclofenac formulation can therefore be administered subcutaneously to any of these sites without clinically significant differences. A further adequately powered study would be necessary to reveal any differences among injection sites in terms of peak plasma concentration.

    The folded intersegmental membrane is a structure that interconnects two adjacent abdominal segments; this structure is distributed in the segments of the honey bee abdomen. The morphology of the folded intersegmental membrane has already been documented. However, the ultrastructure of the intersegmental membrane and its assistive role in the telescopic movements of the honey bee abdomen are poorly understood. To explore the morphology and ultrastructure of the folded intersegmental membrane in the honey bee abdomen, frozen sections were analyzed under a scanning electron microscope. The intersegmental membrane between two adjacent terga has a Z-S configuration that greatly influences the daily physical activities of the honey bee abdomen. The dorsal intersegmental membrane is 2 times thicker than the ventral one, leading to asymmetric abdominal motion. Honey bee abdominal movements were recorded using a high-speed camera and through phase-contrast computed tomography. These movements conformed to the structural features of the folded intersegmental membrane. © The Authors 2016. Published by Oxford University Press on behalf of Entomological Society of America.

    An acute abdomen is one of the main topics among emergency practice for children. We have experienced about 300 acute abdomen cases per year at our Children's Hospital since 1970. Radiological technologists provide a 24-hour emergency service using special knowledge and techniques in our radiological investigation. In the noenatal period esophageal atresia should be diagnosed by plain up-right film with a coiled-up rubber tube, and a contrast examination is contraindicated to prevent severe aspiration pneumonia. In the cases with intestinal atresia, the contrast examination is not necessary again, because the findings of plain film such as the distribution of air-filled intestinal loops, dilated bowel with air-fluid level gives us enough information for the diagnosis of these congenital anomalies. On the contrary, barium enema is useful and harmless for the neonatal age group. It is practical for diagnosing Hirschsprung's disease, midgut malrotation with volvulus, ileal and colonic atresia and necrotizing enterocolitis. An imperforate anus should be classified into the high and low type in the neonatal period to define the treatment. Invertogram is an only way for the differentiation of a baby without external fistula, and we have established the technique for this. The level is diagnosed by the relationship between the gas-filled rectal pouch and ischiac bone. In the infant group intussusception is the most common and urgent acute abdomen. We use a special device to fix the bady, dilute the barium with warm saline (to avoid water intoxication), limit the water pressure to within one meter, and avoid abdominal manipulation and longtime exposure. The successful reduction rate that our team has obtained is almost 85%.

    2005-01-01

    To assess the incidence and diagnostic role of hyperechoic inflammatory fatty tissue (HIFT) in transabdominal ultrasonography (TAUS) for acute abdomen. With TAUS, we examined 98 consecutive patients (68 women, 30 men: mean age, 32 years: age range, 4-84 years) having acute abdominal pain. We examined the abdomen and pelvis by TAUS to determine the cause of acute abdomen, to check for the presence of HIFT, and to investigate whether it was easier and earlier to find the main cause and HIFT presence. We also prospectively evaluated the shape, distribution, and diagnostic role of HIFT. Final diagnoses consisted of 47 cases of acute appendicitis, 14 of enterocolitis, 13 of PID, 7 of gynecological hemoperitoneum, 5 of colonic diverticulitis, 3 of ovarian torsion, 2 of colon perforation, 2 of only presence of non-specific HIFT, 1 of mesenteric lymphadenitis, and 4 of normal. HIFT were seen in 67 patients (68.4%), including 44/47(93.6%) of acute appendicitis, 2/14(14.3%) of enterocolitis, 11/13(84.6%) of PID, 0/7 of hemoperitoneum, 5/5 of colonic diverticulitis, 0/3 of ovarian torsion, 2/2 of colon perforation, and 1/1 mesenteric lymphadenitis. HIFT were detected earlier than the main cause in 17/44 of acute appendicitis, 6/11 of PID, and 4/5 of colonic diverticulitis. In acute appendicitis, the shape of HIFT appeared as fat thickening along the mesoappendix in 12/44, fat thickening along the mesoappendix and the opposite side in 13/44, fat encircled appendix in 6/44, fatty mass wrapping abscess in 10/44, and diffuse intraperitoneal fat thickening in 3/44. In PID, HIFT appeared as a single fatty mass in the pelvis and lower abdomen in 6/11, wrapping pelvic abscess in 2/11, and multiple fatty masses scattered in abdomen and pelvis in 3/11. In colonic diverticulitis, all 5 cases appeared as hyperechoic hemispheric mass covering the inflamed diverticulum. HIFT are a usual US finding in patients with acute abdomen, particularly on abdominal and pelvic inflammatory conditions

    This study aimed to determine the frequency, pattern and management of acute abdomen in patients with dengue fever. This descriptive case series is a prospective analysis of acute abdomen in dengue fever that was performed at three secondary care hospitals in Karachi, Pakistan from June 1, 2005 to December 31, 2008. The inclusion criterion was all patients with confirmed diagnosis of dengue fever. Patients with incomplete laboratory, ultrasound or histopathology data were excluded. Among 357 patients with dengue fever, 43 (12.04%) had acute abdomen. There were 15 men and 28 women, with a median age of 29 years. These included 26 cases of acute cholecystitis, 7 cases of acute appendicitis, 7 cases of nonspecific peritonitis, and 3 cases of acute pancreatitis. Dengue hemorrhagic fever/shock syndrome was found in acute pancreatitis, and two of these patients died. Emergency surgery was required in eight patients (5 appendectomy and 3 open cholecystectomy). Substantial transfusion of blood and its components was required in eight patients who underwent emergency surgery. Early diagnosis and prompt conservative management of dengue acute abdomen is necessary to avoid mortality and emergency surgery-related morbidity. However, if needed, surgery can be performed with acceptable morbidity. Copyright © 2010 Asian Surgical Association. Published by Elsevier B.V. All rights reserved.

    1998-03-01

    We report a case of transient left lateral gaze paresis due to a hemorrhagic lesion restricted in the right precentral gyrus. A 74-year-old female experienced a sudden clumsiness of the left upper extremity. A neurological examination revealed a left central facial paresis, distal dominant muscle weakness in the left upper limb and left lateral gaze paresis. There were no other focal neurological signs. Laboratory data were all normal. Brain CTs and MRIs demonstrated a subcortical hematoma in the right precentral gyrus. The neurological symptoms and signs disappeared over seven days. A recent physiological study suggested that the human frontal eye field (FEF) is located in the posterior part of the middle frontal gyrus (Brodmann's area 8) and the precentral gyrus around the precentral sulcus. More recent studies stressed the role of the precentral sulcus and the precentral gyrus. Our case supports those physiological findings. The hematoma affected both the FEF and its underlying white matter in our case. We assume the lateral gaze paresis is attributable to the disruption of the fibers from the FEF. It is likely that fibers for motor control of the face, upper extremity, and lateral gaze lie adjacently in the subcortical area.

    Full Text Available This report presents a surgical case of postoperative megarectum in an adult patient with imperforate anus/anorectal malformations. A 71-year-old Japanese male presented with a mass in the lower abdomen which was 15 × 12 × 8 cm in diameter, edema in the right lower extremity, and frequent urination. He had undergone sigmoid loop colostomy for an imperforate anus as a newborn infant. At 28 years of age, the sigmoid loop colostomy was changed to sigmoid divided colostomy in the left lower abdomen. Computed tomography revealed a large cystic mass in the lower abdomen. Retrograde urethrography indicated a rectourethral fistula and megarectum with stones. A small laparotomy incision was created in the right lower abdomen, and the wall of the megarectum was identified. Approximately 2,300 mL of gray muddy fluid was identified and drained. A mucous fistula of the upper rectum was created in the right lower abdomen. This is an extremely rare case of postoperative megarectum in an adult patient with an imperforate anus and rectourethral fistula.

  2. Synthesis of a posterior indicator protein in normal embryos and double abdomens of Smittia sp. (Chironomidae, Diptera).

    In embryos of the chironomid midge Smittia, synthesis of a posterior indicator protein designated PI1 (Mr approximately 50,000; pI approximately 5.5) forecasts development of an abdomen as opposed to head and thorax. The protein is synthesized several hours before germ anlage formation. In normal embryos at early blastoderm stages, synthesis of PI1 is restricted to posterior embryonic fragments but not to pole cells. In "double-abdomen" embryos, a mirror-image duplication of the abdomen is formed by cells that would otherwise develop into head and thorax. Embryos were programmed for double-abdomen development by UV irradiation of the anterior pole, and half of them were reprogrammed for normal development by subsequent exposure to visible light (photoreversal). Correspondingly, PI1 was synthesized in anterior fragments of UV-irradiated embryos but not after photoreversal. In a control experiment, UV irradiation of the posterior pole caused neither double-abdomen formation nor PI1 synthesis in anterior fragments. The identity of PI1 formed in anterior fragments of prospective double abdomens with the protein found in posterior fragments was revealed by two-dimensional gel electrophoresis and limited proteolysis. Suppression of PI1 synthesis in anterior fragments of normal embryos is ascribed to the activity of cytoplasmic ribonucleoprotein particles thought to act as anterior determinants.

    Acute abdomen is a medical emergency, in which there is sudden and severe pain in abdomen of recent onset with accompanying signs and symptoms that focus on an abdominal involvement. It can represent a wide spectrum of conditions, ranging from a benign and self-limiting disease to a surgical emergency. Nevertheless, only one quarter of patients who have previously been classified with an acute abdomen actually receive surgical treatment, so the clinical dilemma is if the patients need surgical treatment or not and, furthermore, in which cases the surgical option needs to be urgently adopted. Due to this reason a thorough and logical approach to the diagnosis of abdominal pain is necessary. Some Authors assert that the location of pain is a useful starting point and will guide a further evaluation. However some causes are more frequent in the paediatric population (like appendicitis or adenomesenteritis) or are strictly related to the gender (i.e. gynaechologic causes). It is also important to consider special populations such as the elderly or oncologic patients, who may present with atypical symptoms of a disease. These considerations also reflect a different diagnostic approach. Today, surely the integrated imaging, and in particular the use of multidetector Computed Tomography (MDCT) has revolutionised the clinical approach to this condition, simplyfing the diagnosis but burdening the radiologists with the problems related to the clinical management. However although CT emerging as a modality of choice for evaluation of the acute abdomen, ultrasonography (US) remains the primary imaging technique in the majority of cases, especially in young and female patients, when the limitation of the radiation exposure should be mandatory, limiting the use of CT in cases of nondiagnostic US and in all cases where there is a discrepancy between the clinical symptoms and negative imaging at US.

    To determine distances between patient centroid and gantry isocenter during CT imaging of the chest, abdomen, and/or pelvis, and to evaluate differences based on patient gender, scan region, patient position, and gantry aperture. A water phantom and an anthropomorphic phantom were imaged in the centered position in the CT gantry and at several off-centered positions. Additionally, data from 57,621 adult chest, abdomen, and/or pelvic CT acquisitions were evaluated. Data were analyzed with an analysis of variance using the centroid-to-isocenter data as the dependent variable and the other parameters as independent variables. The majority of patient acquisitions (83.7% (48271/57621)) were performed with the patient's centroid positioned below isocenter (mean 1.7 cm below isocenter (SD 1.8 cm); range 12.1 cm below to 7.8 cm above isocenter). Off-centering in the x-axis was less severe (mean 0.01 cm left of isocenter (SD 1.6 cm)). Distance between centroid and isocenter in the y-axis did not differ as a function of sex but did differ based on scan region, patient position, and gantry aperture. Off-centering is common during CT imaging and has been previously demonstrated to impact dose and image quality. Copyright © 2018 Elsevier Inc. All rights reserved.

    Well-differentiated papillary mesothelioma is a rare tumor occurring predominantly in the peritoneum of young women, a few with history of asbestos exposure. A 28-year-old woman presented with ascites and pain abdomen. Ultrasonography and computed tomography scan of the abdomen revealed a mass in the retroperitoneum measuring 15 cm × 12 cm. Histopathological examination along with immunohistochemistry (IHC) confirmed it to be a papillary mesothelioma in the peritoneum. It is difficult to differentiate from more common malignant mesothelioma and papillary adenocarcinoma, which also have poorer prognosis. The difficulty can be resolved by clinico-radiological correlation along with histopathological examination and IHC.

  11. A Case of Acute Budd-Chiari Syndrome Complicating Primary Antiphospholipid Syndrome Presenting as Acute Abdomen and Responding to Tight Anticoagulant Therapy

    2016-01-01

    Full Text Available A 34-year-old woman with primary antiphospholipid syndrome was admitted to the Gastroenterology Department of our hospital with fever, acute abdomen, watery diarrhea, and extremely high levels of inflammatory parameters. She had a history of left lower limb deep vein thrombosis and pulmonary embolism and was taking warfarin potassium. Acute gastroenteritis was suspected and an antibiotic was administered, but symptoms progressed. Abdominal ultrasonography showed occlusion of the left hepatic vein and the middle hepatic vein and her D-dimer level was high. Accordingly, Budd-Chiari syndrome was diagnosed and high-dose intravenous infusion of heparin was initiated. Her abdominal symptoms improved and the levels of inflammatory parameters and D-dimer decreased rapidly. It is known that antiphospholipid syndrome can be complicated by Budd-Chiari syndrome that usually occurs as subacute or chronic onset, but acute onset is rare. It is difficult to diagnose acute Budd-Chiari syndrome complicating antiphospholipid syndrome and this complication generally has a poor outcome. However, the present case can get early diagnosis and successful treatment with tight anticoagulant therapy.

    A 10-year-old, castrated male domestic short hair cat was presented to the Small Animal Clinic at the Western College of Veterinary Medicine with a presenting complaint of chronic, ocular discharge from the left eye. Ocular examination confirmed epiphora and mucopurulent discharge but there were no apparent reasons for the ocular discharge, and nasolacrimal obstruction was suspected. The cat had swelling of the left side of the face, severe periodontal disease and a fractured upper left canine tooth with pulpal exposure. Dacryocystorhinography revealed narrowing of the nasolacrimal duct above the root of the fractured upper left canine and dental radiographs showed a severe periapical lucency at the apex of the upper left canine tooth. The fractured canine tooth was removed. Subsequently, the ocular discharge and facial swelling resolved. After 2 years, the epiphora has never reoccurred. This is a noteworthy case because a suspected root abscess resulted in extralumenal compression of the nasolacrimal duct, which shows the importance of a thorough oral examination when nasolacrimal obstruction is evident.

    There is a need for an ideal indicator of surgery in patients presenting with acute abdomen. Several markers have been analysed, but the search still continues as none have proven effective. This study aimed to analyse and compare the predictive value of plasma procalcitonin (PCT) strip test in patients presenting with acute abdomen and identify a useful cut-off value to differentiate patients that would benefit with surgery from those that require conservative management. A prospective study was conducted in the department of general surgery from June 2012 to June 2013. Plasma PCT was estimated by the semi-quantitative strip test. The levels of plasma PCT and other routinely used markers of inflammation were analysed and compared. Of the total of 58 patients, 44 patients (76%) were men with a mean age of 45 years. Forty patients required emergency surgical intervention. A plasma PCT value of >0.5 ng/mL at admission was 80% sensitive and 100% specific for predicting need for antibiotics in patients with acute abdomen that were managed conservatively. The mean plasma PCT value in the patients undergoing surgery (5.0-10.0 ng/mL) was significantly more than in those managed conservatively (0.5-2.0 ng/mL). Using receiver operating characteristic (ROC) curves a cut-off for plasma PCT of >5.0 ng/mL was 75% sensitive and 100% specific for considering surgical intervention in patients presenting with acute abdomen. Plasma PCT (value >5 ng/mL) could be used as an adjunct to clinical examination to predict requirement of surgery in patients presenting with acute abdomen. © 2015 Royal Australasian College of Surgeons.

    We describe a patient with sudden onset of abdominal pain and ascites, leading to the diagnosis of autosomal dominant polycystic kidney disease (ADPKD). Her presentation was consistent with acute liver cyst rupture as the cause of her acute illness. A review of literature on polycystic liver disease in patients with ADPKD and current management strategies are presented. This case alerts physicians that ADPKD could occasionally present as an acute abdomen; cyst rupture related to ADPKD may be considered in the differential diagnoses of acute abdomen.

    To selectively visualize the left gastric vein (LGV) with hepatopetal flow information by non-contrast-enhanced magnetic resonance angiography under a hypothesis that change in the LGV flow direction can predict the development of esophageal varices; and to optimize the acquisition protocol in healthy subjects. Respiratory-gated three-dimensional balanced steady-state free-precession scans were conducted on 31 healthy subjects using two methods (A and B) for visualizing the LGV with hepatopetal flow. In method A, two time-spatial labeling inversion pulses (Time-SLIP) were placed on the whole abdomen and the area from the gastric fornix to the upper body, excluding the LGV area. In method B, nonselective inversion recovery pulse was used and one Time-SLIP was placed on the esophagogastric junction. The detectability and consistency of LGV were evaluated using the two methods and ultrasonography (US). Left gastric veins by method A, B, and US were detected in 30 (97%), 24 (77%), and 23 (74%) subjects, respectively. LGV flow by US was hepatopetal in 22 subjects and stagnant in one subject. All hepatopetal LGVs by US coincided with the visualized vessels in both methods. One subject with non-visualized LGV in method A showed stagnant LGV by US. Hepatopetal LGV could be selectively visualized by method A in healthy subjects.

    Background: Vertebral fractures are commonly associated with osteoporosis and have significant morbidity and mortality rates. Osteoporotic vertebral fractures are presently considered as a treatable and preventable condition, and early detection is vital for further management. The evaluation of vertebral compression on multidetector computed tomography (MDCT) scans of the abdomen has, to our knowledge, not been reported before. Purpose: To assess the prevalence of vertebral collapse on routine abdominal CT scans, and to evaluate the usefulness of the multiplanar reconstruction (MPR) capability of MDCT scans in accurately identifying vertebral abnormalities such as vertebral collapse, spondylolisthesis, and retrolisthesis. Material and Methods: A retrospective review of 307 MDCT scans of the abdomen was carried out at a university teaching hospital. Identifiable patient information was anonymized for data protection. All images were reviewed on a picture archiving and communications system (PACS) using sagittal MPR and bone window for the assessment of the vertebrae. Data were collected from the Computerized Radiology Information System (CRIS). Results: Vertebral collapse was seen in 42 (13.6%) of the 307 patients undergoing routine MDCT of the abdomen. Multilevel and single-level collapses were seen in 24 and 18 patients, respectively. Spondylolisthesis was identified in 5.5% (n=17), and retrolisthesis was seen in 0.6% (n=2). All patients with vertebral fracture were older than 50 years. Women were more commonly affected than men. Conclusion: A significant number of patients with vertebral collapse were diagnosed using MPR on MDCT routine scans of the abdomen

    For surgical treatment of esophageal cancer, the importance of evaluating lymph node metastasis and the lymph flow of the esophagus can not be overemphasized. In order to investigate the lymph flow of the esophagus, we preoperatively performed lymphoscintigraphy by endoscopic local injection of 99m Tc Renium Colloid into the esophageal wall in 42 esophageal cancer cases and 4 gastric cancer cases. Postoperatively, the RI uptake of each dissected regional lymph nodes was examined by a Scintillation Counter. The findings were as follows. 1. From the upper third of the thoracic esophagus, the main lymph flow was ascending to the neck and upper mediastinum. 2. From the middle third, the lymph flow was ascending to the neck and upper mediastinum and descending into the abdomen. 3. From the lower third, the main lymph flow was descending to the abdomen. In some cases, the lymph flow to the tracheal bifurcation nodes or to the lymph nodes around the left renal vein was observed. 4. In 61 % of the esophageal cancer cases with a partial bilateral neck dissection, the lymph flow to the bilateral supraclavicular lymph nodes was predominant compared to the upper mediastinum nodes.

    Emphysematous pyelonephritis is a severe, life-threatening infection of the renal parenchyma and perinephric tissues. This condition is primarily encountered in patients with diabetes mellitus or ureteral obstruction, and is characterized by the production of intrarenal and perinephric gas. Emphysematous pyelonephritis is associated with a high degree of morbidity and a high mortality rate. A 72-year-old woman with a history of diabetes mellitus, hypertension, and renal calculi was referred to our emergency department following 6 days of abdominal pain. She suddenly developed pain in the entire abdomen, and was transferred. Physical examination was a distended abdomen with hypoactive bowel sounds. The tenderness was diffuse, but was most prominent in the right upper abdominal quadrant; moreover, rebound tenderness was noted. Laboratory tests revealed a white blood cell count of 4,480/mm(3), platelet count of 17,000/mm(3), creatinine level of 1.64 mg/dl, and serum glucose level of 603 mg/dl. Abdominal computed tomography indicated the presence of free air in the intraperitoneal cavity and right perirenal space, hydronephrosis of the right kidney, and stones in the right distal ureter. After 1 hour, the vital signs changed and she appeared to become drowsy. Therefore, the patient was transferred to the operation room for laparotomy. On exploration of the abdomen, 1.5 L of pus-colored fluid was removed. Although the abdominal viscera and pelvic organs were examined, hollow viscus perforation site could not be observed. Moreover, tissue necrosis and a perforation site were identified at the superior border of the right kidney. Thus, emphysematous pyelonephritis was diagnosed and she underwent right radical nephrectomy. After the surgery, the patient was admitted to the intensive care unit for postoperative management. Follow-up CT performed after 10 days showed fluid collection and hematoma at the nephrectomy site. Hence, percutaneous drainage was performed. Another

    The term ''acute abdomen'' does not describe a specific disease entity but is more a critical clinical state which incorporates very heterogeneous clinical presentations. The prognosis of any disease depends on the time frame from the onset of symptoms to the initiation of a specific therapy. For this reason there are special expectations by clinicians regarding the diagnostic assessment provided by radiology which is expected to deliver an immediate diagnosis supporting further therapeutic decisions. Along with the patient's clinical history, physical examination and blood tests, radiological diagnostics are essential for enabling a specific treatment. From a surgical point of view the radiologist is expected to help in differentiating between cases with indications for emergency surgery and cases eligible for elective surgery or conservative treatment. (orig.) [German] Der Begriff ''akutes Abdomen'' stellt keine eigenstaendige Erkrankung dar, sondern beschreibt einen kritischen klinischen Zustand, unter dessen Oberbegriff sich die unterschiedlichsten Krankheitsbilder subsumieren lassen. Das Zeitintervall zwischen dem Auftreten der ersten Symptome bis zur Einleitung einer gezielten Therapie ist fuer die Prognose der Patienten der entscheidende Faktor. Aus diesem Grund bestehen besondere Anforderungen an die bildgebende Diagnostik, die dazu beitragen soll, innerhalb kuerzester Zeit eine moeglichst genaue Diagnose zu stellen. Neben Anamnese, klinischer Untersuchung und Labordiagnostik stellt die radiologische Untersuchung einen wesentlichen Baustein vor der Therapieeinleitung dar. Aus chirurgischer Sicht muessen Krankheitsbilder, die eine sofortige Notfalloperation erforderlich machen, von Erkrankungen differenziert werden, die eine elektive Chirurgie oder ein konservatives Vorgehen indizieren.

  4. Management of the open abdomen: clinical recommendations for the trauma/acute care surgeon and general surgeon.

    Science.gov (United States)

    Fernández, Luis G

    2016-09-01

    Traditionally, the surgical approach to managing abdominal injuries was to assess the extent of trauma, repair any damage and close the abdomen in one definitive procedure rather than leave the abdomen open. With advances in medicine, damage control surgery using temporary abdominal closure methods is being used to manage the open abdomen (OA) when closure is not possible. Although OA management is often observed in traumatic injuries, the extension of damage control surgery concepts, in conjunction with OA, for the management of the septic patient requires that the general surgeon who is faced with these challenges has a comprehensive knowledge of this complex subject. The purpose of this article is to provide guidance to the acute care and general surgeon on the use of OA negative pressure therapy (OA-NPT; ABTHERA™ Open Abdomen Negative Pressure Therapy System, KCI, an ACELITY Company, San Antonio, TX) for OA management. A literature review of published evidence, clinical recommendations on managing the OA and a case study demonstrating OA management using OA-NPT have been included. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    2016-01-01

    Blunt injury abdomen is the leading cause of morbidity and mortality in all age groups. Blunt trauma differs from penetrating trauma as different organs are characteristically injured by compression from blunt straining. A total of 53 cases of blunt trauma were studied in this study for the period of 1 year. In this study, commonest cause for blunt abdominal trauma was road traffic accident. The maximum incidence was noted in 20-40 middle age group of which 90% male patients were ...

    Primary torsion of the greater omentum is an uncommon cause of acute abdominal pain that mainly affects adults in their fourth or fifth decade. It was first described by Eitel in 1899. Since then, more than 300 cases have been reported in the published literature. Clinical presentation and imaging findings are often of limited value in the diagnosis of primary omental torsion (POT). The patients usually undergo laparotomy for "acute appendicitis" or acute abdomen of poorly defined origin. To provide a detailed description of this rare cause of acute abdomen. We report a case of POT in a woman of reproductive age and discuss contemporary methods in diagnosis and management of the condition. Nowadays, laparoscopy is a safe and effective approach for the diagnosis and management of POT, with the advantages of reduced postoperative pain and hospital stay. Conservative management has also been advocated by some authors in selected patients with a preoperative diagnosis of POT based on computed tomography findings. Copyright © 2013 Elsevier Inc.

    The use of CT in medical diagnosis delivers radiation doses to patents that are higher than those from other radiological procedures. Lack of optimized protocols be an additional source of increased dose in developing countries. The aims of this study are first, to measure patient doses during CT chest and abdomen procedures, second, to estimate the radiation dose to the breast, and third to quantify the radiation risks during the procedures. Patient doses from two common CT examinations were obtained from four hospitals in Khartoum.The patient doses were estimated using measurement of CT dose indexes (CTDI), exposure-related parameters, and the IMPACT spreadsheet based on NRPB conversion factors. A large variation of mean organ doses among hospitals was observed for similar CT examinations. These variations largely originated from different CT scanning protocols used in different hospitals and scanner type. The largest range was found for CT of the chest, for which the dose varied from 2.3 to 47 (average 24.7) mSv and for abdomen CT, it was 1.6 to 18.8 (average 10.2) mSv. Radiation dose to the breast ranged from 1.6 to 32.9 mSv for the chest and 1.1 to 13.2 mSv for the abdomen. The radiation risk per procedure was high. The obtained values were mostly higher than the values of organ doses reported from the other studies. It was concluded that current clinical chest and abdomen protocols result in variable radiation doses to the breast. The magnitude of exposure may have implications for imaging strategies.(Author)

    A persistent anastomosis between the pulmonary veins that connect with the left atrium and the systemic vein that drains into the right atrium has occasionally been reported. We report characteristics and transcatheter therapy in partially abnormal pulmonary venous return with additional drainage to the left atrium. We retrospectively studied such patients in 5 institutions. Ten patients (6 girls) presented at a median age of 8 (0.1 to 54) years with 2 anatomic types: 8 vertical vein types with drainage of the left upper lobe to the innominate vein via a large vertical vein (left superior cardinal vein) and to the left atrium via the left upper pulmonary vein; and 2 scimitar vein (SV) types with drainage of the right middle and lower pulmonary veins into the inferior vena cava and to the left atrium via an anomalous connecting vein. Associated malformations were aortic coarctation (n=2) and secundum atrial septal defects (n=3). Two patients of the vertical vein type were operated. Transcatheter occlusion of the abnormal pulmonary venous return was performed in 7 cases, associated with occlusion of systemic arterial supply (n=2), secundum atrial septal closure (n=2), left upper pulmonary vein stenosis stenting (n=1), and coarctation stenting (n=1). Including previously published cases, 18 patients (13 vertical veins and 5 scimitar veins) underwent transcatheter repair. Patients over 40 years of age tend to be symptomatic at presentation (p=0.056). In partially abnormal pulmonary venous return with dual drainage, transcatheter therapy can be offered in the majority of patients. © 2013.

  10. Diagnostics of vascular diseases as a cause for acute abdomen

    International Nuclear Information System (INIS)

    Juchems, M.S.; Aschoff, A.J.

    2010-01-01

    Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding.

    Isolated left-sided partial anomalous pulmonary venous connection with intact interatrial septum is a rare diagnosis in childhood. In these cases, a vertical vein drains the left upper pulmonary lobe into the brachiocephalic vein and finally to the right atrium. Surgical treatment is performed to prevent right ventricular failure and pulmonary artery disease in advanced age. In this report, the rare entity of isolated left-sided anomalous pulmonary venous connection in a 14-year-old girl and successful minimally invasive surgery without cardiopulmonary bypass are described.

    Unusual locations of the appendix vermiformis can result in delay in appropriate diagnosis and treatment of appendicitis. So an inflamed appendix in a sub-hepatic caecum caused by caecal maldescent for example can mimic cholecystitis, the pain being localized in the right upper quadrant. Here, we present a case of perforated sub-hepatic appendicitis with peritonitis, requiring open ileocaecal resection. Review of the existing literature has demonstrated that this pathology is uncommon, yet not so rare as one might presume. In conclusion, surgeons should be aware of this possibility in the diagnostic and therapeutic management of acute abdomen. Copyright © 2016. Published by Elsevier GmbH.

    Two cases of anatomical variations of the thymus are presented with respect to the anatomical relations with the left brachiocephalic vein and found during the necropsy process. Less than 2 days after birth with Noonan Syndrome, when the left brachiocephalic vein was scanning behind the upper thymus horns, there were other adjacent lesions consisting of three supernumerary spleens and three hepatic veins. The second case was an 8-year-old infant with child malpractice who died from urinary sepsis due to obstructive uropathy, in which case the upper lobes of the thymus were fused and formed a ring through which the left brachiocephalic vein passed.

    The severity of clinical activity of Crohn's disease is high during the first year after diagnosis and decreases thereafter. Approximately 50% of patients require steroids and immunosuppressants and 75% need surgery during their lifetime. The clinical course of patients with Crohn's disease first diagnosed at surgery has never been investigated. To assess the clinical course of Crohn's disease first diagnosed at surgery for acute abdomen and to evaluate the need for medical and surgical treatment in this subset of patients. Hospital clinical records of 490 consecutive Crohn's disease patients were reviewed. Patients were classified according to the Vienna criteria. Sex, extraintestinal manifestations, family history of inflammatory bowel diseases, appendectomy, smoking habit and medical/surgical treatments performed during the follow-up period were assessed. Kaplan-Meier survival method and Cox proportional hazards regression model. Of the 490 Crohn's disease patients, 115 had diagnosis of Crohn's disease at surgery for acute abdomen (Group A) and 375 by conventional clinical, radiological, endoscopic and histologic criteria (Group B). Patients in Group A showed a low risk of further surgery (Log Rank test pacute abdomen showed a low risk for reintervention and less use of steroids and immunosuppressants during follow-up than those not operated upon at diagnosis. Early surgery may represent a valid approach in the initial management of patients with Crohn's disease, at least in the subset of patients with ileal and complicated disease.

    2017-12-01

    Full Text Available Warfarin is an oral anticoagulant, which is commonly used in the treatment and prophylaxis of thromboembolic conditions. Bleeding is the primary adverse effect associated with warfarin. The majority of warfarin-related bleedings are spontaneous minor hemorrhages occurring in the subcutaneous or intramuscular tissues and can be treated by decreasing the dose of oral anticoagulants. However, although rare, it is possible to encounter spontaneous major bleedings with increased risk of mortality. Conservative approach is the preferred initial therapy for hemodynamically stable patients with major intra-abdominal hemorrhages that we define as the intermediate group patients. Nevertheless, surgery is required for hemodynamically unstable patients with acute abdominal pain in cases of ongoing active hemorrhage, generalized peritonitis, obstruction, acute abdomen, intestinal ischemia, and perforation. In this article, we present a rare case of acute abdomen and spontaneous intra-abdominal hemorrhage resulting from uncontrolled use of warfarin and a new classification requirement.

    Abdominal pain of sudden onset is the hallmark of most non-traumatic emergency surgical presentations. This presents a scenario of urgency to the young surgeon who has to determine which of a myriad of disease conditions the patient is presenting with. Such a physician has to rely on experience and a sound knowledge of the local aetiological spectrum in making a clinical diagnosis. To determine the epidemiology and aetiological spectrum of diseases presenting as acute abdomen in the adult population at the hospital surgical emergency unit. Two hundred and seventy-six patients presenting at the University of Ilorin Teaching Hospital emergency unit and managed by the general surgeons between 1(st) of May 2009 and 30(th) of April 2010 were recruited and followed-up throughout the period of admission. The biodata and clinical information inclusive of diagnosis, investigations, treatment modality and outcome were entered in a structured questioner. Standardised treatment was given to all patients and difficulties encountered in their management were also noted. The data collected was evaluated using SPSS16. Acute abdomen constituted 9.6% of total surgical emergency admissions with patients aged 16-45 years constituting 78.3%. The commonest cause of acute abdomen was appendicitis (30.3%) followed by intestinal obstruction (27.9%), perforated typhoid ileitis 14.9% and peptic ulcer disease (7.6%), respectively. The result from the study is similar to what has been reported in other tropical settings with inflammatory lesions being the major problem. There is also a rising incidence of post-operative adhesions and gradual decline in incidence of obstructed hernia.

    Wound control in laparostomy for the treatment of intra-abdominal hypertension remains challenging and numerous techniques have been described. We report the first UK experience with a new commercially available device specifically designed to facilitate management of the open abdomen. A 44-year-old gentleman presented with a 3-day history of constant severe epigastric pain and associated vomiting. Amylase was markedly elevated and he was admitted for supportive management of pancreatitis, with subsequent transfer to intensive care due to severe systemic inflammatory syndrome. The patient decompensated, developing intra-abdominal hypertension with renal and respiratory failure. This was successfully managed by performing a laparostomy and using an ABThera™ Open Abdomen Negative Pressure Therapy System (KCI, San Antonio, TX). We describe its use to facilitate wound control, including enteroatmospheric fistula, allowing granulation and eventual restoration of gastrointestinal continuity 383-days after admission. We found the ABThera™ System proved to be a useful treatment adjunct, protecting intra-abdominal contents while removing large volumes of exudate and infected material from within the abdominal cavity. Complex cases such as this remain infrequent and this article provides a summary of our experience, including a review of indications for laparostomy and the underlying basic science in this difficult area. © 2012 The Authors.

    Full Text Available Upper septal fascicular ventricular tachycardia is a very rare form of idiopathic fascicular ventricular tachycardia. Upper septal fascicular tachycardia uses the posterior fascicle as the anterograde limb and the septal fascicle as the retrograde limb. When evaluating the electrocardiography for this form of tachycardia, the presence of narrow QRS morphology and normal axis may be misinterpreted as supraventricular tachycardia. Here, we report a very rare subtype of fascicular tachycardia that originates more proximally in the His-Purkinje system at the base of the heart.

    AIM: Oral contrast media are commonly given prior to computed tomography (CT) examination of the upper abdomen. Although positive oral contrast media are normally used, there is increasing interest in using negative agents such as water and less commonly fat density products. The aim of this study was to compare a positive oral contrast medium, water, and a diluted emulsion of arachis oil (Calogen[reg], a fat density food supplement) for assessment of the upper abdomen. MATERIALS AND METHODS: Seventy-one patients referred for upper abdominal CT were randomized to receive either 500 ml water, 2% sodium diatrizoate or a dilute suspension of Calogen[reg]. The CT images were scored independently by three radiologists. Distension and anatomical identification was assessed for the stomach, duodenum and jejunum; with anatomical identification recorded for the pancreas, retroperitoneum, liver, gallbladder and spleen. RESULTS: Dilute Calogen[reg] produced a significant improvement (P < 0.01) in distension and anatomical visualization of the stomach and proximal duodenum. Only minimal differences were demonstrated between the three contrast media for visualization of more distal small bowel or identification of the other upper abdominal viscera. Significantly more artifacts were caused by positive contrast media than with the Calogen[reg] mixture. CONCLUSION: A dilute suspension of Calogen[reg] as an oral contrast medium is recommended when disease is suspected within the stomach or proximal duodenum. Ramsay, D.W. et al. (2001)

    One of the challenges of multidetector computerized tomography is to minimize the risk of ionizing radiation using optimized protocols since higher doses are necessary to obtain high image quality. It was also noted that, due to the geometry in image acquisition using MDCT becomes necessary to estimate dose values consistent with the hypothesis clinically and with the specificities of the tomographic equipment. The aim of this study was to estimate the doses in abdomen exams from the data recorded on the MDCT console and dimensions obtained from DICOM images of patients undergoing different clinical protocols. Were collected, from the image DICOM of 101 exams, values of the dose length product (DLP) provided by Philips Health Care - Brilliance 64 equipment console, in order to relate them with the dose values obtained by means of thermoluminescent dosimeters ( TLD ) of CasSo 4 :Mn placed on the surface of a cylindrical simulator abdomen acrylic manufactured under the technical - operational conditions for a typical abdomen exam. From the data obtained, it was possible to find a factor of 1.16 ( 5 % ) indicating that the DLP values Brilliance 64 console underestimate the doses and this should be used with correction factor to estimate the total dose of the patient.

    2014-02-01

    Laparoscopy has become a routine procedure in the management of acute abdominal disease and can be considered both an excellent therapeutic and additional diagnostic tool in selected cases. However, a high level of expertise in laparoscopic and emergency surgery is required. Hemodynamic instability, huge abdominal distension, fecal peritonitis and perforated cancer are relative contraindications for the laparoscopic approach. In recent years, abdominal emergencies have increasingly been managed successfully by laparoscopy. In acute appendicitis, acute cholecystitis and perforated peptic ulcer, randomized controlled trials have proven that the laparoscopic approach is as safe and as effective as open surgery, with fewer complications and a quicker postoperative recovery. Other indications such as blunt and penetrating trauma to the abdomen, small bowel occlusion and perforated diverticular disease are under debate, indicating that more randomized controlled trials comparing laparoscopic and open surgery are still necessary.

    Magnetic resonance electrical impedance tomography (MREIT) is a new bio-imaging modality providing cross-sectional conductivity images from measurements of internal magnetic flux densities produced by externally injected currents. Recent experimental results of postmortem and in vivo imaging of the canine brain demonstrated its feasibility by showing conductivity images with meaningful contrast among different brain tissues. MREIT image reconstructions involve a series of data processing steps such as k-space data handling, phase unwrapping, image segmentation, meshing, modelling, finite element computation, denoising and so on. To facilitate experimental studies, we need a software tool that automates these data processing steps. In this paper, we summarize such an MREIT software package called CoReHA (conductivity reconstructor using harmonic algorithms). Performing imaging experiments of the postmortem canine abdomen, we demonstrate how CoReHA can be utilized in MREIT. The abdomen with a relatively large field of view and various organs imposes new technical challenges when it is chosen as an imaging domain. Summarizing a few improvements in the experimental MREIT technique, we report our first conductivity images of the postmortem canine abdomen. Illustrating reconstructed conductivity images, we discuss how they discern different organs including the kidney, spleen, stomach and small intestine. We elaborate, as an example, that conductivity images of the kidney show clear contrast among cortex, internal medulla, renal pelvis and urethra. We end this paper with a brief discussion on future work using different animal models

    2010-01-01

    Extraosseous Ewing's sarcoma is a rare tumor of neuroectodermal origin. It presents mainly in the soft tissue of the extremities and thorax. Histologically, it is similar to Ewing's sarcoma of the bone. We present the case of a male who arrived at the emergency room with acute abdomen, leucocytosis and imaging techniques (abdominal ultrasound and computed tomography) suggestive of complicated diverticular disease. He was treated with emergency surgery. Intraoperative findings were an unsuspected tumor (20 x 15 x 15 cm). Treatment consisted of extirpation of the tumor, separating it from the adjacent viscera and followed by chemotherapy based on epirubicin, cyclophosphamide and vincristine for six cycles. Because the control abdominal CT demonstrated tumor activity in the retroperitoneum adjacent to the ascending colon and cecum, further resection was decided upon. In a review of the literature, no previous reports of extraosseous Ewing's sarcoma were found presenting as acute abdomen. Due to the rarity of this tumor, only case reports or series have been found in the literature without randomized or comparative studies. Surgery was the cornerstone of treatment, without reports of preoperative chemotherapy. If the patient's condition permits, percutaneous needle biopsy is mandatory to obtain optimum treatment as well as to improve prognosis.

  10. A rare diagnosis of abdominal pain presentation in the emergency department: Idiopathic omental bleeding: A case report.

    2017-12-01

    Idiopathic omental bleeding is a rare cause of acute abdomen, with only a few reported cases. It usually presents with abdominal pain and may be life-threatening. As it rarely occurs, it may not be considered initially during patient presentation. A 35-year-old male came to our emergency department with abdominal pain present for around 5 to 6 hours. The patient complained of left upper quadrant abdominal pain after eating breakfast. The only associated symptom was 3 episodes of vomiting up food. Physical examination revealed mild left upper quadrant abdominal tenderness without muscle guarding or rebounding pain. Blood examination showed leukocytosis with neutrophil predominance and C reactive protein elevation. The pain was persistent and relief was not obtained by medication. Computed tomography showed a large lobular-contour homogenous slightly hyperdense lesion without enhancement along the greater curvature of the stomach in the lesser sac. A surgeon was consulted and laparotomy was suggested. Hematoma was found at Morrison pouch, subsplenic fossa, and lesser sac under operation. Laparotomy and ligation for hemostasis. The patient was discharged with stable condition after 7 days of hospitalization. This diagnosis should be considered in patients presenting with epigastric pain and vomiting after eating while in the emergency department because this disease might be life-threatening. This case highlights 2 important learning points. First, idiopathic omental bleeding could occur after eating in patients without underlying disease or trauma history, and this disease should be taken into consideration when acute abdomen occurs. Second, emergent laparotomy is indicated if the cause of acute abdomen is not clear. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

  11. Visualization of the Left Extraperitoneal Space and Spatial Relationships to Its Related Spaces by the Visible Human Project

    Background The major hindrance to multidetector CT imaging of the left extraperitoneal space (LES), and the detailed spatial relationships to its related spaces, is that there is no obvious density difference between them. Traditional gross anatomy and thick-slice sectional anatomy imagery are also insufficient to show the anatomic features of this narrow space in three-dimensions (3D). To overcome these obstacles, we used a new method to visualize the anatomic features of the LES and its spatial associations with related spaces, in random sections and in 3D. Methods In conjunction with Mimics® and Amira® software, we used thin-slice cross-sectional images of the upper abdomen, retrieved from the Chinese and American Visible Human dataset and the Chinese Virtual Human dataset, to display anatomic features of the LES and spatial relationships of the LES to its related spaces, especially the gastric bare area. The anatomic location of the LES was presented on 3D sections reconstructed from CVH2 images and CT images. Principal Findings What calls for special attention of our results is the LES consists of the left sub-diaphragmatic fat space and gastric bare area. The appearance of the fat pad at the cardiac notch contributes to converting the shape of the anteroexternal surface of the LES from triangular to trapezoidal. Moreover, the LES is adjacent to the lesser omentum and the hepatic bare area in the anterointernal and right rear direction, respectively. Conclusion The LES and its related spaces were imaged in 3D using visualization technique for the first time. This technique is a promising new method for exploring detailed communication relationships among other abdominal spaces, and will promote research on the dynamic extension of abdominal diseases, such as acute pancreatitis and intra-abdominal carcinomatosis.

    1974-07-01

    A Monte Carlo computer program is performed to study the effects of an abdomen dodger. For this study the inhomogeneous Snyder phantom is assumed to be irradiated by an X-ray tube operated at 80 kV. By the use of a dodger which compensates the varying thickness of the body the exposure distribution on the photoreceptor can be made more uniform and the absorbed dose decreases. As different patients have different dimensions, the results presented here cannot be applied for any given abdomen examination, but can be used as average values, characteristic for an average examination, thus applicable in the estimations for the total population.

    The biogenic magnetic properties of the honeybee Apis mellifera were investigated with a view to understanding the bee's physiological response to magnetic fields. The magnetisations of bee abdomens on one hand, and heads and thoraxes on the other hand, were measured separately as functions of temperature and field. Both the antiferromagnetic responses of the ferrihydrite cores of the iron storage protein ferritin, and the ferrimagnetic responses of nanoscale magnetite (Fe{sub 3}O{sub 4}) particles, were observed. Relatively large magnetite particles (ca. 30 nm or more), capable of retaining a remanent magnetisation at room temperature, were found in the abdomens, but were absent in the heads and thoraxes. In both samples, more than 98% of the iron atoms were due to ferritin.

    Currently, the open abdomen technique is the widely recognised method for treatment of life-threatening trauma, intra-abdominal sepsis, abdominal compartment syndrome and wound dehiscence. The techniques for temporary closure using negative pressure have gained increasing popularity. Although negative pressure wound therapy has been proved as an effective method in trauma, the results in diffuse peritonitis are contradictory. Overall, 108 patients with diffuse peritonitis and open abdomen were prospectively enrolled from January 2006 to December 2013--69 treated with mesh-foil laparostomy without negative pressure and 49 with vacuum-assisted closure (VAC(®)) The primary endpoints were the rate of primary fascial closure and mortality. The secondary outcomes were the rate of complications--enteroatmospheric fistulas, intra-abdominal abscesses, wound infection and necrotising fasciitis, intensive care unit (ICU) and overall hospital stay. VAC was associated with higher overall (73% vs 53%) and late primary fascial closure rates (31% vs 7%), lower rates of necrotising fasciitis (2% vs 15%, p=0.012), intra-abdominal abscesses (10% vs 20%), enteroatmospheric fistulas (8% vs 19%), overall mortality (31% vs 53%, pVAC in comparison to the temporary abdominal closure without negative pressure in the cases with severe diffuse peritonitis. However, to a large extent, our results might be attributed to the combination of VAC with dynamic fascial closure. Published by the BMJ Publishing Group Limited.

    Full Text Available Discoid Lupus Erythematosus (DLE is an autoimmune disorder that usually occurs on sun exposed areas of head and neck. Infrequently it could be presented by palpebral involvement and rarely unilateral upper eye lid edema and erythema have been reported as the sole manifestation of DLE. We describe a 38-year-old woman with chronic left upper eye lid edema and erythema from one year ago which was induced by steroid injection for left eyebrow alopecia. Histopathologic and direct immunofluorescent studies were made on palpebral skin tissue and confirmed DLE diagnosis. Antinuclear antibody (ANA titer was 1/160 with speckled pattern. She was treated by oral hydroxychloroquine (400 mg daily with moderate improvement after three months. We should think about DLE in cases with chronic upper eye lid edema and erythema. The aim of this case report is to emphasize that ophthalmologist and dermatologists should be aware of different presentations of DLE in the periorbital area to prevent misdiagnosis.

    ESWL is a safe and efficient method in the therapy of urolithiasis which, however, is not free of complications. ESWL was performed in a 54-year-old patient with a stone of 18 mm in size located in one of the upper calyces of the left kidney. Several hours after the ambulatory ESWL treatment the patient was admitted to the emergency room with strong pain in the left lumbar region and the upper abdomen. During examination low blood pressure, tachycardia and low Hb levels were found. Ultrasound and CAT scans revealed a subcapsular rupture of the spleen. Surgery was indicated, and a laparotomy with splenectomy was performed. Ten days after surgery the patient developed acute pancreatitis which was treated conservatively with success. Although ESWL is a safe method in the treatment of urinary stones with a relatively small number of complications, rare complications like ruptures of the spleen have to be considered. Special attention should be given to patients with kidney stones in the left upper calyces, pathological growth of the spleen, and accompanying diseases such as chronic heart failure or hypertension. In such patients ESWL should not be performed on an outpatient basis.

    A 54-year-old male with partial denture underwent stereotactic radiosurgery with an infrared camera-guided system for a metastatic brain tumor arising from lung cancer. Although this method utilizes a biteplate mounted on the upper jaw to detect head movement, the patient only had four teeth in his upper jaw. In order to stabilize the biteplate, the maxillary denture was fixed to the biteplate with an autopolymerizing resin. In addition, the rest-occlusal position of the lower jaw was impressed on the inferior surface of the biteplate with an autopolymerizing resin. To assess reproducibility and stability, the distance between the left and right incus and left and right markers was measured during pre-planning, as well as before and after stereotactic irradiation. Wearing the biteplate ensures the accuracy of radiotherapy planning for the implementation of radiosurgery in patients who have many maxillary teeth missing. However, a large degree of error was observed when the biteplate was removed. (author)

    In order to clarify the validity of indication criteria of the conservative treatment for perforated upper gastrointestinal tract, a retrospective study was carried out. We enrolled 28 patients with perforation of the gastrointestinal tract who were determined to receive conservative treatment at the time of hospitalization from January 2000 to December 2007. When the following criteria were satisfied, we treated the patients by the conservative treatment after informed consent was gained from them and their families: stable condition of vital signs; peritoneal signs localized in the upper abdomen; and no or slight fluid collection at the Douglas' pouch determined by computed tomography. Patients who showed changes for the worse of peritonitis or increased fluid collection during follow-up were promptly converted to surgery. Six patients were converted to surgery, but all of them were discharged very much improved. We compared patient's data of the conservative treatment group and the converted surgery group at the time of consultation. All data were not statistically different between two groups. If all criteria are satisfied, it seemed that we can start conservative treatment for perforated gastrointestinal tract with careful observation and the system of prompt conversion to operation for patients who showed changes for the worse of peritonitis or increased fluid collection.

    This purpose of this study was to investigate the immediate effects of plantar inputs on both the upper half muscle activity (anterior temporal, masseter, digastric, sternocleidomastoid, upper and lower trapezius, cervical) and the body posture, by means of electromyography (EMG) and vertical force platform, respectively. Twenty four (24) healthy adults, between the ages of 24 and 31 years (25.3 +/- 1.9), with no history of craniomandibular disorder or systemic musculoskeletal dysfunction, were randomly divided into two groups: test group (fourteen subjects) and control group (ten subjects). A first recording session (TO) measured the baseline EMG and postural patterns of both groups. After this session, the test group wore test shoes with insoles that stimulated the plantar surfaces, while the control group wore placebo shoes. After one hour, a second set of measurements (T1) were performed. Significant differences between the groups at baseline were observed in the left anterior temporal, left cervical, and left upper trapezius, as well as at T1 in the left anterior temporal and right upper trapezius (p postural blindness in the test group compared to the control group was observed. Further studies are warranted to investigate the short and long-term effects of this type of insole, in patients with both craniomandibular-cervical and lower extremity disorders.

  3. Blunt liver injury with intact ribs under impacts on the abdomen: a biomechanical investigation.

    Directory of Open Access Journals (Sweden)

    Yu Shao

    Full Text Available Abdominal trauma accounts for nearly 20% of all severe traffic injuries and can often result from intentional physical violence, from which blunt liver injury is regarded as the most common result and is associated with a high mortality rate. Liver injury may be caused by a direct impact with a certain velocity and energy on the abdomen, which may result in a lacerated liver by penetration of fractured ribs. However, liver ruptures without rib cage fractures were found in autopsies in a series of cases. All the victims sustained punches on the abdomen by fist. Many studies have been dedicated to determining the mechanism underlying hepatic injury following abdominal trauma, but most have been empirical. The actual process and biomechanism of liver injury induced by blunt impact on the abdomen, especially with intact ribs remained, are still inexhaustive. In order to investigate this, finite element methods and numerical simulation technology were used. A finite element human torso model was developed from high resolution CT data. The model consists of geometrically-detailed liver and rib cage models and simplified models of soft tissues, thoracic and abdominal organs. Then, the torso model was used in simulations in which the right hypochondrium was punched by a fist from the frontal, lateral, and rear directions, and in each direction with several impact velocities. Overall, the results showed that liver rupture was primarily caused by a direct strike of the ribs induced by blunt impact to the abdomen. Among three impact directions, a lateral impact was most likely to cause liver injury with a minimum punch speed of 5 m/s (the momentum was about 2.447 kg.m/s. Liver injuries could occur in isolation and were not accompanied by rib fractures due to different material characteristics and injury tolerance.

    Physical examination of the abdomen is an essential skill. Knowledge of its clinical anatomy and application is vital for making diagnoses. Misinterpretation of anatomy during examination can have serious consequences. This review addresses understanding of the anatomy, methodology, and complications of abdominal physical examination. It includes particular reference to modern technology and investigations. Physical examination is performed for diagnostic purposes. However, the art of physical examination is declining as more and more clinicians rely on newer technology. This can have regrettable consequences: negligence, waste of time and resources, and deterioration of clinical skills. With a sound knowledge of clinical anatomy, and realization of the importance of physical examination of the abdomen, clinician, and patients alike can benefit. Clin.

    Full Text Available Idiopathic rupture of the urinary bladder is an uncommon condition and represents less than 1% of all bladder rupture cases. In most of the cases the main etiological factor was heavy alcohol ingestion. A combined injury of the spleen and bladder is a very rare condition that is almost often associated with trauma and foreign bodies. In this paper we present the extremely rare clinical course of acute abdomen caused by a combined spontaneous intraperitoneal injury; spontaneous rupture of the urinary bladder and spleen. According to our opinion, spontaneous bladder rupture caused by bladder distension due to alcohol ingestion led to urinary ascites and abdominal distension. Finally, repeated minor abdominal blunt trauma during everyday life, to a moderately distended abdomen caused a spontaneous splenic rupture in the patient with abnormal coagulation studies.

  6. Comparison of Outcomes between Early Fascial Closure and Delayed Abdominal Closure in Patients with Open Abdomen: A Systematic Review and Meta-Analysis

    2014-01-01

    Full Text Available Up to the present, the optimal time to close an open abdomen remains controversial. This study was designed to evaluate whether early fascial abdominal closure had advantages over delayed approach for open abdomen populations. Medline, Embase, and Cochrane Library were searched until April 2013. Search terms included “open abdomen,” “abdominal compartment syndrome,” “laparostomy,” “celiotomy,” “abdominal closure,” “primary,” “delayed,” “permanent,” “fascial closure,” and “definitive closure.” Open abdomen was defined as “fail to close abdominal fascia after a laparotomy.” Mortality, complications, and length of stay were compared between early and delayed fascial closure. In total, 3125 patients were included for final analysis, and 1942 (62% patients successfully achieved early fascial closure. Vacuum assisted fascial closure had no impact on pooled fascial closure rate. Compared with delayed abdominal closure, early fascial closure significantly reduced mortality (12.3% versus 24.8%, RR, 0.53, P<0.0001 and complication incidence (RR, 0.68, P<0.0001. The mean interval from open abdomen to definitive closure ranged from 2.2 to 14.6 days in early fascial closure groups, but from 32.5 to 300 days in delayed closure groups. This study confirmed clinical advantages of early fascial closure over delayed approach in treatment of patients with open abdomen.

    In about 1970 the detection of cardiac and pulmonary right-to-left shunts by means of the intravenous injection of Technetium 99-marked albumin-macroaggregates was introduced and until now this determination method is the most simple and most precisely one. After the injection the main part of the particles reaches the lungs and is fixed there, the shunt-part is fixed in the systemic circulation in the organs with the best blood supply, i.e. brain, kidneys and liver. From a quantitative whole-body scintigram or from partial scintigrams of head, lungs and abdomen the relation of pulmonary and extrapulmonary activity is calculated, which corresponds precisely to the proportional right-to-left shunt. This method is illustrated by examples of its clinical application. (orig.) [de

    Objective: This course will give an overview of the role of radiation therapy in the treatment of gastrointestinal malignancies in the upper abdomen, with an emphasis on carcinomas of the stomach, pancreas and biliary tract. For each site, information will be presented related to failure patterns with conventional surgical treatment and the indications for surgery for different stages of disease. The possible uses of radiation therapy as an adjuvant to surgical resection will be discussed as well as the use of radiation therapy alone. In addition, the combination of radiation therapy with chemotherapy will be discussed for each of these sites, as well as the information available at present as to the optimal way to combine chemotherapy with radiation therapy. Radiation therapy is not generally accepted to have a role in the treatment of patients with adenocarcinomas of the stomach. This is related to the fact that gastric cancer has been standardly treated with surgical resection alone, and delivery of high dose radiation therapy to the upper abdomen can be difficult because of the sensitivity of nearby normal tissues. Nonetheless, data on failure patterns suggest that local recurrence is common in patients with disease through the gastric wall and with positive nodes. Although there is some suggestive data to indicate that radiation therapy is effective as an adjuvant, results of an ongoing trial will be necessary for determination of the exact role of radiation therapy. Possible uses of radiation therapy as preoperative therapy or given alone will also be briefly discussed. Radiation therapy has been often used in the treatment of pancreatic adenocarcinomas, either alone or combined with surgical resection. Its use is more common for this site both because of the extremely poor prognosis of standard therapies, and because of the difficulty in performing an adequate surgical resection. Data will be reviewed suggesting that radiation therapy has a role when

    Breast support reduces breast pain and movement during exercise, however, an extra layer of clothing may affect thermoregulation. This preliminary study investigated female upper body and breast skin temperature and thermal comfort following short-duration exercise. Eight female participants with C-cup breasts had thermal images (infra-red camera, FLIR systems) of the bare breasts, the breasts in two sports bras (composite and polyester) and the abdomen, taken before and after 20 min of exercise at 28(o)C. Following exercise, bare-breast, bra and abdomen temperatures reduced by 0.61(o)C, 0.92(o)C and 2.06(o)C, respectively. The polyester sports bra demonstrated greater thermal comfort and enabled a greater change in skin temperature than the composite sports bra. It is concluded that following short-duration exercise, sports bras reduced the cooling ability of the breast. Material properties of the bras affect thermal comfort and post-exercise skin temperature; this should be an important consideration for sports bra manufacturers. This study investigates the effect of sports bras on thermal regulation of the breast following exercise. Sports bras negatively affected the cooling ability of the skin on the breast, with the material properties of the bra affecting thermal comfort following exercise. These results present important considerations for sports bra manufacturers.

    Severe superimposed infection during open abdomen treatment with development of intra-abdominal sepsis is a challenging complication associated with high mortality rates. We report our experience with VAC-Instill therapy (KCI, San Antonio, USA) used for treatment of an infected open abdomen following pancreatic surgery. A literature search revealed no analogous case reports using VAC-Instill therapy for treatment of an infected laparostomy. The encouraging result of the case presented seems to indicate that VAC-Instill therapy could be used as adjunctive treatment in the management of the infected open abdomen when traditional therapy fails to control the infection.

    This paper describes a method designed to model the repaired herniated human abdomen just after surgery and examine its static mechanical response to the maximum intra-abdominal pressure provoked by a physiological movement (standing cough). The model is based on the real geometry of the human abdomen bearing a large incisional hernia with several anatomical structures differentiated by MRI. To analyze the outcome of hernia repair, the surgical procedure was simulated by modeling a prosthesis placed over the hernia. Three surgical meshes with different mechanical properties were considered: an isotropic heavy-weight mesh (Surgipro®), a slightly anisotropic light-weight mesh (Optilene®), and a highly anisotropic medium-weight mesh (Infinit®). Our findings confirm that anisotropic implants need to be positioned such that the most compliant axis of the mesh coincides with the craneo-caudal direction of the body.

    Introduction: This study tends to test the capacity of the computed tomography in assist in the diagnosis and the approach of the acute abdomen. Material and method: This is a longitudinal and prospective study, in which were analyzed the patients with the diagnosis of acute abdomen. There were obtained 105 cases of acute abdomen and after the application of the exclusions criteria were included 28 patients in the study. Results: Computed tomography changed the diagnostic hypothesis of the physicians in 50% of the cases (p < 0.05), and the confidence index in 85.71% of the cases (p 0.014). Computed tomography also altered the management in 46.43% of the cases (p > 0.05), where 78.57% of the patients had surgical indication before computed tomography and 67.86% after computed tomography (p = 0.0546). The index of accurate diagnosis of computed tomography, when compared to the anatomopathologic examination and the final diagnosis, was observed in 82.14% of the cases (p = 0.013). When the analysis was done dividing the patients in surgical and nonsurgical group, were obtained an accuracy of 89.28% (p 0.0001). The difference of 7.2 days of hospitalization (p = 0.003) was obtained compared with the mean of the acute abdomen without use the computed tomography. Conclusion: The computed tomography is correlative with the anatomopathology and has great accuracy in the surgical indication, associated with the capacity of increase the confident index of the physicians, reduces the hospitalization time, reduces the number of surgeries and is cost-effective.

    Cerebral gas embolism as a result of upper gastrointestinal endoscopy is a rare complication and bares a high morbidity. A patient is presented who underwent an upper endoscopy for evaluation of a gastric-mediastinal fistula after subtotal oesophagectomy and gastric tube reconstruction because of oesophageal cancer. During the procedure, cerebral gas emboli developed resulting in an acute left-sided hemiparesis. After hyperbaric oxygen therapy, the patient recovered almost completely. The aetiology and treatment is discussed based on the reviewed literature. Once cerebral gas emboli are recognized, patient outcome can be improved by hyperbaric oxygen therapy.

    Full text: In our previous work an individual dose adaptation in abdomen of paediatric patients has been showed at the Meyer children hospital of Florence. For each kV really feasible in our MSCT scanner, a table of mAs versus abdomen thickness and width ratio has been developed only on the basis of water cylinder phantoms. The choice of the water arise by the fact that in pediatric patient the quantity of water inside the body is major than that of adult. In this way a reduction dose has showed with respect to the ordinary paediatric scanning protocol in use before and the same image quality has been preserved in the case of an optimized CT scanning technique of a standard adult patient of height 175 cm and weight 70 kg. However these results were only theoretical because relied on water phantoms. Now this work concerns the clinical validation of our dose reduction study on phantoms. So 50 examinations were acquired with the dose reduction scanning technique and scored randomly, without knowing weight and height of patient by three radiologists. These scores were compared with that of other 50 abdomen examination before dose reduction study. The scores refers to the noise perceived by radiologist and to the diagnostic quality of radiograph. As last, a score on the low contrast tissue separation between muscle and fat and a score on visibility of structure therein have been asked to the radiologists. The same work has concerned the abdomen examinations with iodine contrast medium. In this study the score of each radiographs has been catalogued in four range of age, 0 - 1; 1 - 3; 3 - 8; 8 - 13 years. Aligned rank and Wilcoxon's signed rank tests were used for statistical analyses. The table of modulating mAs with respect to the size of patient obtained with only water phantom study has been revised so that none reduced detection in low-visibility structures like fat or muscle or liver was evident. Nevertheless a reduction in CTDI of 30 % has been reached in our new

    Objectives: Carcinoma of unknown primary (CUP) in the abdomen and pelvis is a heterogeneous group of cancers with no standard treatment. Considered by many to be incurable, these patients are often treated with chemotherapy alone. In this study, we determined the effectiveness of radiation therapy in combination with chemotherapy in patients with CUP in the abdomen and pelvis. Patients and Methods: Medical records were reviewed for 37 patients with CUP treated with radiation therapy for disease located in the soft tissues and/or nodal basins of the abdomen and pelvis at University of Texas M.D. Anderson Cancer between 2002 and 2009. All patients underwent chemotherapy, either before or concurrent with radiation therapy. Patients were selected for radiation therapy on the basis of histologic type, disease extent, and prior therapy response. Twenty patients underwent definitive radiation therapy (defined as radiation therapy targeting all known disease sites with at least 45 Gy) and 17 patients underwent palliative radiation therapy. Only 6 patients had surgical resection of their disease. Patient and treatment characteristics were extracted and the endpoints of local disease control, progression-free survival (PFS), overall survival (OS), and treatment-related toxicity incidence were analyzed. Results: The 2-year PFS and OS rates for the entire cohort were 32% and 57%, respectively. However, in patients treated with definitive radiation therapy, the rates were 48% and 76%, and 7 patients lived more than 3 years after treatment with no evidence of disease progression. Nevertheless, radiation-associated toxicity was significant in this cohort, as 40% experienced Grade 2 or higher late toxicities. Conclusions: The use of definitive radiation therapy should be considered in selected patients with CUP in the soft tissues or nodal basins of the abdomen and pelvis.

    Objective: Combined liposuction and abdominoplasty, or lipoabdominoplasty, is particularly helpful in sculpting a more aesthetically pleasing abdominal contour, particularly in the supraumbilical midline groove. This groove, coined the "champagne groove" by one of our patients, is a frequently sought-after attribute by patients. However, liposuction adds time and cost to an already costly abdominoplasty. We sought to create this groove without the addition of liposuction, utilizing what we call a champagne groove lipectomy. This study reports on our champagne groove lipectomy technique and compares our complication rates with those reported in the literature for standard abdominoplasty techniques. Methods: This is a retrospective review of a single surgeon's experience at our institution over a 6-year period (2007-2012). A total of 74 patients undergoing consecutive abdominoplasty were studied, all female nonsmokers. Two groups were recognized: 64 of 74 patients underwent abdominoplasty, partial belt lipectomy, and champagne groove lipectomy, while 10 of 74 patients underwent fleur-de-lis abdominoplasty without champagne groove lipectomy. Results: Overall, 10 of 74 patients (13.5%) suffered some type of complication, which compares favorably with reported rates in the literature. The majority of complications were related to delayed wound healing or superficial wound dehiscence. Among those patients who underwent champagne groove lipectomy, complications occurred in 6 of 64 patients (9.3%), versus 4 of 10 (40%) patients undergoing fleur-de-lis abdominoplasty. Conclusions: Champagne groove lipectomy is a cost-effective alternative to lipoabdominoplasty for achieving an aesthetically pleasing upper midline abdominal contour, with complication rates comparing favorably with those reported in the literature.

    Diffusion-weighted magnetic resonance imaging (DW-MRI) provides qualitative and quantitative information of tissue cellularity and the integrity of cellular membranes. Since DW-MRI can be performed without ionizing radiation exposure and contrast media application, DW-MRI is a particularly attractive tool for patients with allergies for gadolinium-based contrast agents or renal failure. Recent technical developments have made DW-MRI a robust and feasible technique for abdominal imaging. DW-MRI provides information on the detection and characterization of focal liver lesions and can also visualize treatment effects and early changes in chronic liver disease. In addition DW-MRI is a promising tool for the detection of inflammatory changes in patients with Crohn's disease. (orig.) [German] Die diffusionsgewichtete (DW-)MRT ermoeglicht die Erfassung qualitativer und quantitativer Informationen bzgl. der Gewebezellularitaet und Membranintegritaet. Die DW-MRT ist insbesondere bei Patienten mit einer Allergie gegen gadoliniumhaltige Kontrastmittel oder eingeschraenkter Nierenfunktion attraktiv, da ihr Einsatz nicht mit Strahlenexposition oder Kontrastmittelgabe verbunden ist. Durch technische Weiterentwicklungen ist die robuste Anwendung der DW-MRI in der Bildgebung des Abdomens seit einiger Zeit moeglich geworden. In der Leberdiagnostik lassen sich Zusatzinformationen zur Detektion und Charakterisierung von Leberlaesionen gewinnen, aber auch Therapieerfolge dokumentieren und fruehe chronische Leberveraenderungen visualisieren. Neben ihrer Rolle bei hepatologischen und onkologischen Fragestellungen erscheint der Einsatz der DW-MRT zudem bei entzuendlichen Fragestellungen wie dem Morbus Crohn sehr viel versprechend. (orig.)

    Full Text Available BACKGROUND Trauma is “the neglected disease of modern developing nations.” Hollow viscous injury following blunt trauma to abdomen is not common. The incidence of hollow viscous injuries following abdominal trauma varies from 2 to 15%. The following study was conducted at Department of General Surgery, MKCG Medical College and Hospital, Berhampur, a tertiary care hospital. MATERIALS AND METHODS All the patients admitted to MKCG Medical College and Hospital, Berhampur, with history of blunt trauma to abdomen were examined carefully. Those patients with symptoms and signs suggestive of visceral injury were identified and subjected to xray chest and abdomen erect view and ultrasound abdomen/CT scan. Those with features of pneumoperitoneum are subjected to laparotomy and treated according to location of perforation. Duration of study was from January 2016 to July 2017. RESULTS This study included people of different age groups from 13 to 65 years. Majority of the patients were men (83.5% and most common mode was found to be road traffic accident (69.6%. Most of the patients injured were young and belonged to earning group (81.44%. Most common viscera injured was ileum (37.85% Most common type of injury encountered in our study was isolated perforation and the common surgical procedure was primary closure. CONCLUSION In cases of polytrauma, blunt abdominal trauma contributes significantly to morbidity and mortality. Both the sexes were affected with a male preponderance. The most common mode of blunt trauma was found to be Road Traffic Accident (RTA. Adequate knowledge regarding suspecting intra-abdominal injuries and timely management at tertiary care centre can definitely bring a marked difference in the prognosis of polytrauma patients with history of blunt trauma to abdomen.

    Intussusception in adults is very rarely seen, and this cause acute abdomen. A computed tomography (CT) scan, clinical suspicion, history, and a physical examination are important for the diagnosis. We present two cases of colonic intussusceptions induced by lipoma. The cases had similar locations, diagnoses, and management. Both lipomas were located close to the cecum in the ascending colon, and a right segmental colon resection was performed in both cases. The follow-up of both cases was uneventful. Although benign lesions can cause colonic intussusception, the high incidence of malignancy in colonic lesions should always be considered. Therefore, oncologic surgical procedures should be applied. The definitive diagnosis can be made by histopathology. Sertkaya M, Emre A, Pircanoglu EM, Yazar FM, Tepe M, Cengiz E, Isler A, Vicdan H.

    We report the case of a very large anomalous connection of the veins draining the upper lobe of the left lung to both the left-sided vertical vein and the left atrium, associated with mild rheumatic mitral valve stenosis, in which the atrial septum was intact and the remaining venous system, including the coronary sinus, was otherwise normal (a variant of Lutembacher's syndrome). In order to abolish the left-to-right shunting, a transcatheter approach to close this venous structure was successfully attempted using an Amplatzer ASD Occluder device. The technical aspects and the alternative options of performing a procedure with a device for a purpose outside the scope of its approved label are discussed.

    MELAS (mitochondrial cytopathy, encephalomyopathy, lactic acidosis and stroke-like episodes) is a syndrome in which signs and symptoms of gastrointestinal disease are uncommon if not rare. We describe the case of a young woman who presented as an acute surgical emergency, diagnosed as toxic megacolon necessitating an emergency total colectomy. MELAS syndrome was suspected postoperatively owing to persistent lactic acidosis and neurological symptoms. The diagnosis was later confirmed with histological and genetic studies. This case highlights the difficulties in diagnosing MELAS because of its unpredictable presentation and clinical course. We therefore recommend a high index of suspicion in cases of an acute surgical abdomen with additional neurological features or raised lactate.

    Patients managed with upper limb cast immobilization often seek advice about driving. There is very little published data to assist in decision making, and advice given varies between healthcare professionals. There are no specific guidelines available from the UK Drivers and Vehicles Licensing Agency, police, or insurance companies. Evidence-based guidelines would enable clinicians to standardize the advice given to patients. Six individuals (three male, three female; mean age 36 years, range 27-43 years) were assessed by a mobility occupational therapist and driving standards agency examiner while completing a formal driving test in six different types of upper limb casts (above-elbow, below-elbow neutral, and below-elbow cast incorporating the thumb [Bennett's cast]) on both left and right sides. Of the 36 tests, participants passed 31 tests, suggesting that most people were able to safely drive with upper limb cast immobilization. However, driving in a left above-elbow cast was considered unsafe.

    Focused assessment with sonography for trauma (FAST) is a limited ultrasound examination, primarily aimed at the identification of the presence of free intraperitoneal or pericardial fluid. In the context of blunt trauma abdomen (BTA), free fluid is usually due to hemorrhage, bowel contents, or both; contributes towards the timely diagnosis of potentially life-threatening hemorrhage; and is a decision-making tool to help determine the need for further evaluation or operative intervention. Fifty patients with blunt trauma abdomen were evaluated prospectively with FAST. The findings of FAST were compared with contrast-enhanced computed tomography (CECT), laparotomy, and autopsy. Any free fluid in the abdomen was presumed to be hemoperitoneum. Sonographic findings of intra-abdominal free fluid were confirmed by CECT, laparotomy, or autopsy wherever indicated. In comparing with CECT scan, FAST had a sensitivity, specificity, and accuracy of 77.27, 100, and 79.16 %, respectively, in the detection of free fluid. When compared with surgical findings, it had a sensitivity, specificity, and accuracy of 94.44, 50, and 90 %, respectively. The sensitivity of FAST was 75 % in determining free fluid in patients who died when compared with autopsy findings. Overall sensitivity, specificity, and accuracy of FAST were 80.43, 75 and 80 %, respectively, for the detection of free fluid in the abdomen. From this study, we can safely conclude that FAST is a rapid, reliable, and feasible investigation in patients with BTA, and it can be performed easily, safely, and quickly in the emergency room with a reasonable sensitivity, specificity, and accuracy. It helps in the initial triage of patients for assessing the need for urgent surgery.

    Mitochondrial damage-associated molecular patterns (mtDAMPs), such as mitochondrial DNA and N-formylated peptides, are endogenous molecules released from tissue after traumatic injury. mtDAMPs are potent activators of the innate immune system. They have similarities with bacteria, which allow mtDAMPs to interact with the same pattern recognition receptors and mediate the development of systemic inflammatory response syndrome (SIRS). Current recommendations for management of an open abdomen include returning to the operating room every 48 hours for peritoneal cavity lavage until definitive procedure. These patients are often critically ill and develop SIRS. We hypothesized that mitochondrial DAMPs are present in the peritoneal cavity fluid in this setting, and that they accumulate in the interval between washouts. We conducted a prospective pilot study of critically ill adult patients undergoing open abdomen management in the surgical and trauma intensive care units. Peritoneal fluid was collected daily from 10 open abdomen patients. Specimens were analyzed via quantitative polymerase chain reaction (qPCR) for mitochondrial DNA (mtDNA), via enzyme immunoassay for DNAse activity and via Western blot analysis for the ND6 subunit of the NADH: ubiquinone oxidoreductase, an N-formylated peptide. We observed a reduction in the expression of ND6 the day after lavage of the peritoneal cavity, that was statistically different from the days with no lavage (% change in ND6 expression, postoperative from washout: -50 ± 11 vs. no washout day, 42 ± 9; p abdomen. It is possible that increased frequency of peritoneal cavity lavage may lead to decreased systemic absorption of mtDAMPs, thereby reducing the risk of SIRS. Prospective study, Case Series, Level V.

    Objective: The purpose of this work was to analysis the most suggestive imaging findings of Castleman disease in the abdomen and pelvis and to improve the recognition of this rare disease. Methods: Ten patients with pathologically proved Castleman disease in the abdomen (n=9) and pelvis (n=1) were included in this study. Patients were 18-56 yeas old (mean=40); 7 were men and 3 women. Imaging findings (CT and MRI, n=4; only CT, n=4; only MRI, n=2) were retrospectively reviewed and correlated with clinical and pathologic findings. Results: The lesions were divided into localized (n=9) and disseminated (n=1) group. The pathologic subtypes of all 9 cases of localized disease were hyaline vascular type. Imaging findings showed a single large mass in six and a single dominant mass with small satellite nodules in three. On plain CT images, the lesions manifested as homogeneous soft masses, which is isoattenuating to muscle. After intravenous injection of contrast media, most of the masses enhanced sharply (5/7) with the attenuation similar to large arteries at arterial phase and delay scans. On MR imaging, the lesions also were homogenous and had isointense or slightly low signal intensity compared with that of muscle on T 1 weighted images and high signal intensity on T 2 weighted images, and showed contrast enhancement in a similar pattern to contrast enhanced CT. After intravenous injection of contrast media, areas of central lower radial attenuation in the mass were noted in 4 cases of large masses ( > 5 cm) and proved to be fibrotic component pathologically. The pathologic subtypes of 1 cases of disseminated disease was plasma cell type. Imaging findings showed several well-defined nodules lied in the retroperitoneal zone that enhanced sharply with the attenuation similar to large arteries after intravenous injection of contrast media. Conclusion: Imaging findings of Castleman disease in the abdomen and pelvis are closely associated with its pathology. The most

    To identify the non-obstetric causes and presentation of acute abdomen among pregnant women. This was a cross sectional hospital-based study among 128 pregnant women by face to face interview using a semi-structured questionnaire. This study was conducted at the Gynecology & Obstetric Ward of 250 Bed General Hospital, Noakhali, Bangladesh, from January to August 2013. Data were analyzed by a software package used for statistical analysis (SPSS) version 11.5 (SPSS, Inc., Chicago, IL, USA). Mean age of participants was 25±4 years. Our findings showed that 81% were Muslim, 67% were lower middle income group, as well as 47% completed primary level of education. The results revealed that 28% had biliary ascariasis, 24% had peptic ulcer disease and 10% had lower urinary tract infection. We also found that 6% had acute pyelonephritis, 6% had acute gastroenteritis, 6% had acute cholecystitis, 6% had acute appendicitis, 2% had acute pancreatitis, 3% had choledocolithiasis, 2% had ovarian solid mass, 2% had twisted ovarian cyst, 4% had renal colic, and 1% had renal calculus. In non-obstetrical presentation of acute abdomen, the study found that 84% of respondents complained their pain lasting more than 24 hours. Besides, half of respondents felt pain in epigastrium and right hypochondrium. Cramping, prickling and aching type of pain were more, while 66% suffered from continuous pain. Our results also showed that 73% did not explain any aggravating factor and relieving factor, and the rest said food, fasting state and position change aggravated pain as well as relieved pain. The study concludes that precise diagnosis of the acute abdomen in pregnant women by continual updating of abdominal assessment knowledge, and clinical skills is necessary in the management of abdominal pain in obstetric settings.

    The aim was to determine the incidence of seed migration not only to the chest, but also to the abdomen and pelvis after transperineal interstitial prostate brachytherapy with loose 125 I seeds. We reviewed the records of 267 patients who underwent prostate brachytherapy with loose 125 I seeds. After seed implantation, orthogonal chest radiographs, an abdominal radiograph, and a pelvic radiograph were undertaken routinely to document the occurrence and sites of seed migration. The incidence of seed migration to the chest, abdomen, and pelvis was calculated. All patients who had seed migration to the abdomen and pelvis subsequently underwent a computed tomography scan to identify the exact location of the migrated seeds. Postimplant dosimetric analysis was undertaken, and dosimetric results were compared between patients with and without seed migration. A total of 19,236 seeds were implanted in 267 patients. Overall, 91 of 19,236 (0.47%) seeds migrated in 66 of 267 (24.7%) patients. Sixty-nine (0.36%) seeds migrated to the chest in 54 (20.2%) patients. Seven (0.036%) seeds migrated to the abdomen in six (2.2%) patients. Fifteen (0.078%) seeds migrated to the pelvis in 15 (5.6%) patients. Seed migration occurred predominantly within two weeks after seed implantation. None of the 66 patients had symptoms related to the migrated seeds. Postimplant prostate D90 was not significantly different between patients with and without seed migration. We showed the incidence of seed migration to the chest, abdomen and pelvis. Seed migration did not have a significant effect on postimplant prostate D90

    Ecchymosis and/or haematoma are the most common adverse events after subcutaneous administration of low molecular weight heparin. There is no strong recommendation as to the puncture site. To evaluate the adverse events, ecchymosis and/or haematoma after the administration of prophylactic subcutaneous enoxaparin in the abdomen vs the arm in the critically ill patient. A randomised, two-arm clinical trial (injection in the abdomen vs the arm), performed between July 2014 and January 2017, in an 18-bed, polyvalent intensive care unit. Patients receiving prophylactic enoxaparin, admitted >72h, with no liver or haematological disorders, a body mass index (BMI) >18.5, not pregnant, of legal age and with no skin lesions which would impede assessment were included. We excluded patients who died or who were transferred to another hospital before completing the evaluation. We gathered demographic and clinical variables, and the onset of ecchymosis and/or haematomas at the injection site after 12, 24, 48 and 72hours. A descriptive analysis was undertaken, with group comparison and logistic regression. The study was approved by the ethics committee with the signed consent of patients/families. 301 cases (11 excluded): 149 were injected in the abdomen vs 141 in the arm. There were no significant differences in demographic and clinical variables, BMI, enoxaparin dose or antiplatelet administration [ecchymosis, abdomen vs arm, n(%): 66(44) vs 72(51), P=.25] [haematoma abdomen vs arm, n(%): 9(6) vs 14(10), P=.2]. Statistical significance was found in the size of the haematomas after 72h: [area of haematoma (mm 2 ) abdomen vs arm, median (IQR): 2(1-5.25) vs 20(5.25-156), P=.027]. In our patient cohort, prophylactic subcutaneous enoxaparin administered in the abdomen causes fewer haematomas after 72hours, than when administered in the arm. The incidence rate of ecchymosis and haematoma was lower than the published incidence in critically ill patients, although patients receiving

    Gastroenteropancreatic neuroendocrine neoplasia (GEP-NEN) are a heterogeneous group of complex tumors, which is often difficult to classify due to heterogeneity and varying locations. Ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron-emission tomography computed tomography (PET/CT) are available for the localization of NEN as well as for the staging. In particular, nuclear medical examination methods with somatostatin analogues are of great importance since radioactively labeled receptor ligands make tumors visible with high sensitivity. CT and MRT have high detection rates for GEP-NEN and have been further improved by developments such as diffusion weighted imaging. The nuclear medical methods, however, are superior in detection, especially in gastrointestinal NEN It is important for the radiologist to become acquainted with the NEN as they can occur ubiquitously in the abdomen and should be identified as such. Since GEP-NEN are predominantly hypervascularized, a biphasic examination technique is obligatory for contrast-enhanced cross-sectional imaging. PET/CT with somatostatin analogs should be used for further diagnosis. (orig.) [German] Gastroenteropankreatische neuroendokrine Neoplasien (GEP-NEN) sind eine heterogene Gruppe komplexer Tumoren, deren Einteilung aufgrund der Heterogenitaet und unterschiedlichen Lokalisation haeufig schwerfaellt.

    MRI of the abdomen currently competes with CT and ultrasonography as an imaging technique for abdominal pathology. Although ultrasonography has certain advantages, such as real-time scanning, the major comparison is to be made between MR and CT. CT has slightly superior spatial resolution and minimal motion artifacts, and enables the use of contrast agents in bowel. MR, on the other hand, has improved capabilities in contrasting soft tissues and providing multiplanar imaging. The greatest advantage of CT is the experience that the medical community has gained with it over the last decade. Further development in technology and improvement in the clinical experience with MR will be important in determining its future role in abdominal imaging. Large series of clinical trials are required for further experience. Chemical spectroscopy with proton and possibly other nuclei may improve diagnostic specificity. Paramagnetic contrast agents for bowel specification would certainly improve imaging quality. Thus, MR will play a significant role in abdominal imaging in the future

    Full Text Available The hepatic and renal veins drain into the inferior vena cava. The upper group of hepatic veins consists of three veins which extend to the posterior face of the liver to join the inferior cava. The left renal vein passes anterior to the aorta just below the origin of the superior mesenteric artery. We detected a variation in the hepatic and renal veins in a multislice CT angiogram of a nine-year-old male patient in the Radiology Department of Afyon Kocatepe University Medical School. The upper group hepatic veins normally drains into the inferior vena cava as three separate trunks, namely the right, left and middle. In our case, we found that only the right and left hepatic veins existed and the middle hepatic vein was absent. Furthermore, the left renal vein, which normally passes anterior to the abdominal aorta, was retro-aortic. Left renal vein variations are of great importance in planning retroperitoneal surgery and vascular interventions. Knowledge of a patient’s hepatic vein and renovascular anatomy and determining their variations and anomalies are of critical importance to abdominal operations, transplantations and preoperative evaluation of endovascular interventions.

    Torsion of uterine adnexa is an important cause of acute abdominal pain in females. The main organ which can cause torsion is the ovaries, but torsions of the fallopian tube, subserosal myoma, paratubal cyst, and even the uterine body have been reported. The incidence of isolated fallopian tubal torsion is very rare. Even more rarely, it can coil around nearby organs such as the utero-ovarian ligament, showing similar clinical manifestations with those of adnexal torsion. We experienced an extremely rare case of acute abdomen induced by ovarian congestion triggered by the fallopian tube accompanying a paratubal cyst coiling around the utero-ovarian ligament. The right paratubal cyst was misinterpreted as being part of a cystic component of the left ovary on preoperative sonographic examination, and the coiling of the right fallopian tube accompanying the paratubal cyst was misdiagnosed as torsion of the right ovary. We report this rare case with a brief literature review.

    The association between social capital and health-related quality of life (HRQoL) has not been thoroughly studied among older persons in rural China, especially among those who were left behind or not. This study investigates the association between social capital and HRQoL and examines possible differences of this association between being left behind or not in rural China. A cross-sectional survey of 825 people aged 60 years and older, residing in three rural counties in Jiangsu Province in China, was conducted in 2013. Factor analysis was performed to measure social capital. EQ-5D was used to measure HRQoL. Tobit regression analysis with upper censoring was conducted to explore the association between social capital and EQ-5D index. After controlling for individual characteristics, low social capital and being left behind were significantly associated with low HRQoL. Old people with low social capital had 0.055 lower EQ-5D index compared to those with high social capital. Old people being left behind had 0.040 lower EQ-5D index compared to those who were not left behind. For different dimensions of social capital, the main effects came from the domain of trust and reciprocity. There was a significant interaction between low social capital and being left behind on HRQoL, suggesting that low social capital was associated with low HRQoL among persons left behind. Our findings indicate that the left behind old people with low social capital were a potentially vulnerable group in rural China. Formulating and implementing initiatives and strategies which increase social capital may foster better HRQoL, especially for old people who were left behind.

    To compare the effectiveness, adverse effects, and cost-effectiveness of percutaneous neurolytic celiac plexus block (NCPB) versus traditional medication strategies for the treatment of patients with advanced cancer having severe upper abdominal cancer pain. This retrospective study included 81 patients with advanced upper abdominal cancer admitted to The Sixth People's Hospital Affiliated to Shanghai Jiaotong University between January 2013 and July 2014. The patients were divided into percutaneous NCPB (treatment) and medication for pain (control) groups. The outcomes were measured in terms of Numeric Rating Scale (NRS) score and Karnofsky Performance Status (KPS) score before treatment and on the 3rd, 7th, 14th, and 28th days posttreatment. The effectiveness and cost-effectiveness of the therapy were assessed using analysis of the health economics. The improvements in NRS score (1.42 ± 1.09 vs 4.03 ± 0.96, P economics evaluation revealed that the medicine-specific costs and total health care costs were significantly reduced in the treatment group compared to the control group ( P .05) were seen in the costs of hospitalization, examinations, and treatment. The percutaneous NCPB method shows promising results and better cost-effectiveness for treating patients with advanced cancer having severe upper abdominal pain.

    Two patients presented with recurrent, massive haemoptysis. Arteriography, including thoracoabdominal aortograms, revealed in both cases large non-bronchial collaterals arising from the left gastric artery. In the first case the non-bronchial collateral supplied the upper left lobe and in the second case it supplied the middle right lobe. Percutaneous embolisation of bronchial and non-bronchial collateral branches has become an accepted procedure in controlling massive or recurrent haemoptysis. Accurate identification of the non-bronchial collateral arterial feeders is essential for successful embolotherapy. (orig.)

    Full Text Available Asymmetry of parkinsonian symptoms is strong evidence toward the diagnosis of Parkinson's disease (PD. Lower body parkinsonism is characteristic in idiopathic normal pressure hydrocephalus (INPH. We report an unusual INPH patient with marked asymmetric and upper body parkinsonism. An 83-year-old man presented with gait impairment and asymmetric clumsiness of movement. According to the Unified Parkinson's Disease Rating Scale (UPDRS, the motor subscore was 12 in the left limb and 8 in the right. The score was 14 for both the upper and lower body. After the cerebrospinal fluid tap test (CSFTT, he showed marked improvement in the upper body score. A loss of asymmetry of parkinsonian signs, with greater improvement in the left limb, was presented. Fluorinated N-3-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl-nortropane (F-18 FP-CIT positron emission tomography (PET imaging was normal. In the differential diagnosis of elderly patients presenting with parkinsonism compatible with PD, we might need to consider a diagnosis of INPH.

    Bimanual visuomotor movement training (BMT) enhances the excitability of human preparatory premotor and primary motor (M1) cortices compared to unimanual movement. This occurs when BMT involves mirror symmetrical movements of both upper-limbs (in-phase) but not with non-symmetrical movements (anti-phase). The neural mechanisms mediating the effect of BMT is unclear, but may involve interhemispheric connections between homologous M1 representations as well as the dorsal premotor cortices (PMd). The purpose of this study is to assess how intermittent theta burst stimulation (iTBS) of the left PMd affects left M1 excitability, and the possible combined effects of iTBS to left PMd applied before a single session of BMT. Left M1 excitability was quantified using transcranial magnetic stimulation (TMS) in terms of both the amplitudes and spatial extent of motor evoked potentials (MEPs) for the extensor carpi radialis (ECR) before and multiple time points following (1) BMT, (2) iTBS to left PMd or (3) iTBS to left PMd and BMT. Although there was not a greater increase in either specific measure of M1 excitability due to the combination of the interventions, iTBS applied before BMT showed that both the spatial extent and global MEP amplitude for the ECR became larger in parallel, whereas the spatial extent was enhanced with BMT alone and global MEP amplitude was enhanced with iTBS to left PMd alone. These results suggest that the modulation of rapid functional M1 excitability associated with BMT and iTBS of the left PMd could operate under related early markers of neuro-plastic mechanisms, which may be expressed in concurrent and distinct patterns of M1 excitability. Critically, this work may guide rehabilitation training and stimulation techniques that modulate cortical excitability after brain injury. Copyright © 2013 Elsevier B.V. All rights reserved.

    Wandering spleen is a rare entity, which is defined as the presence of the spleen in other than the left upper quadrant of the abdomen. The etiology of wandering spleen is unknown. Congenital factors such as incomplete fusion or laxity of the supporting structures of the spleen and acquired factors such as splenomegaly, trauma, abdominal laxity and hormonal effects of pregnancy may play a role. The clinical presentation is variable from asymptomatic to catastrophic if torsion of the splenic pedicle occurs. We present two cases of wandering spleen with a brief review of the literature.

    A 16-year old male patient was admitted to hospital because of a fainting episode which was accompanied by diarrhoea that was dark red. All investigations were normal except a low haematocrit, a technetium-99m pertechnetate abdominal scan, which showed a large area of moderate activity in the upper left abdomen, and digital subtraction angiography, which showed bleeding in the same area where the abnormal finding on the pertechnetate scan was found. Ectopic gastric mucosa and a deep ulcer in an otherwise normal jejunum were found during the urgent exploratory laparotomy. (orig.).

  11. Honey bees (Apis mellifera ligustica) swing abdomen to dissipate residual flying energy landing on a wall

    Whether for insects or for aircrafts, landing is one of the indispensable links in the verification of airworthiness safety. The mechanisms by which insects achieve a fast and stable landing remain unclear. An intriguing example is provided by honeybees (Apis mellifera ligustica), which use the swinging motion of their abdomen to dissipate residual flying energy and to achieve a smooth, stable, and quick landing. By using a high-speed camera, we observed that touchdown is initiated by honeybees extending their front legs or antennae and then landing softly on a wall. After touchdown, they swing the rest of their bodies until all flying energy is dissipated. We suggested a simplified model with mass-spring dampers for the body of the honeybee and revealed the mechanism of flying energy transfer and dissipation in detail. Results demonstrate that body translation and abdomen swinging help honeybees dissipate residual flying energy and orchestrate smooth landings. The initial kinetic energy of flying is transformed into the kinetic energy of the abdomen's rotary movement. Then, the kinetic energy of rotary movement is converted into thermal energy during the swinging cycle. This strategy provides more insight into the mechanism of insect flying, which further inspires better design on aerial vehicle with better landing performance.

    Splenic artery aneurysm is rare and its diagnosis is challenging due to the nonspecific nature of the clinical presentation. We report a case of a splenic artery aneurysm in which the patient presented with chronic dyspepsia and multiple episodes of minor intragastric bleeding. A 60-year-old, previously healthy Sri Lankan man presented with four episodes of hematemesis and severe dyspeptic symptoms over a period of 6 months. The results of two initial upper gastrointestinal endoscopies and an abdominal ultrasound scan were unremarkable. A third upper gastrointestinal endoscopy detected a pulsatile bulge at the posterior wall of the gastric antrum. A contrast-enhanced computed tomogram of his abdomen detected a splenic artery aneurysm measuring 3 × 3 × 2.5 cm. While awaiting routine surgery, he developed a torrential upper gastrointestinal bleeding and shock, leading to emergency laparotomy. Splenectomy and en bloc resection of the aneurysm with the posterior stomach wall were performed. Histology revealed evidence for a true aneurysm without overt, acute, or chronic inflammation of the surrounding gastric mucosa. He became completely asymptomatic 2 weeks after the surgery. Splenic artery aneurysms can result in recurrent upper gastrointestinal bleeding. The possibility of impending catastrophic bleeding should be remembered when managing patients with splenic artery aneurysms after a minor bleeding. Negative endoscopy and ultrasonography should require contrast-enhanced computed tomography to look for the cause of recurrent upper gastrointestinal bleeding.

    In North Trent, UK, an entrance dose survey of lateral lumbar spine and antero-posterior (AP) abdomen examinations has been carried out in 17 radiology departments. The survey comprised 294 lateral lumbar spine and 322 AP abdomen entrance dose measurements. The mean entrance doses were found to be approximately half of the relevant national reference entrance dose levels of 30 mGy and 10 mGy, respectively. The effect of generator waveform on entrance dose was studied by separating the generators into two types: ''pulsating potential'' (PP) generators and ''constant potential'' (CP) generators for each examination. PP generators comprised 23% of the total number of examinations. The mean entrance dose and radiographic exposure factors from CP generators were found to be significantly lower than those from PP generators. The use of CP type generators, together with low attenuation components can significantly reduce patient entrance doses for these examinations. (author)

    We report here an ectopic case of Fasciola hepatica infection confirmed by recovery of an adult worm in the mesocolon. A 56-year-old female was admitted to our hospital with discomfort and pain in the left lower quadrant of the abdomen. Abdominal CT showed 3 abscesses in the left upper quadrant, mesentery, and pelvic cavity. On surgical exploration, abscess pockets were found in the mesocolon of the sigmoid colon and transverse colon. A leaf-like worm found in the abscess pocket of the mesocolon of the left colon was diagnosed as an adult fluke of F. hepatica. Histologically, numerous eggs of F. hepatica were noted with acute and chronic granulomatous inflammations in the subserosa and pericolic adipose tissues. Conclusively, a rare case of ectopic fascioliasis has been confirmed in this study by the adult worm recovery of F. hepatica in the mesocolon.

    The X-ray machines used for radiodiagnosis should meet certain quality assurance programmes. These are necessary to have good quality radiographs at reasonably low exposure to patients. Materials and Methods: Dose reduction methods in abdomen X-ray examination were carried out in 10 hospitals in Tehran. This paper presents the work, which was implemented on 200 patients and evaluated using the entrance skin dose in the Anterior-Posterior abdomen projection measured directly at the center of the X-ray field. In addition, the machine room, and dark room parameters, as well as work practices and repeat rates were studied. Results: The quality control parameters and the entrance skin dose were evaluated utilizing an anthropologic phantom to define the optimal exposure condition at all hospitals before and after quality control . Results show that after using the quality control parameters and optimization of the exposure conditions, the mean of mAs and entrance skin dose can be decreased by 62% and 65% respectively. Conclusion: The quality of the radiographs generally increased. The reported method is easily implemented in any clinical situation where optimization of abdomen radiography is necessary

    To compare the efficacy of a repetitive task-specific practice regimen integrating a portable, electromyography-controlled brace called the 'Myomo' versus usual care repetitive task-specific practice in subjects with chronic, moderate upper extremity impairment. Sixteen subjects (7 males; mean age 57.0 ± 11.02 years; mean time post stroke 75.0 ± 87.63 months; 5 left-sided strokes) exhibiting chronic, stable, moderate upper extremity impairment. Subjects were administered repetitive task-specific practice in which they participated in valued, functional tasks using their paretic upper extremities. Both groups were supervised by a therapist and were administered therapy targeting their paretic upper extremities that was 30 minutes in duration, occurring 3 days/week for eight weeks. One group participated in repetitive task-specific practice entirely while wearing the portable robotic, while the other performed the same activity regimen manually. The upper extremity Fugl-Meyer, Canadian Occupational Performance Measure and Stroke Impact Scale were administered on two occasions before intervention and once after intervention. After intervention, groups exhibited nearly identical Fugl-Meyer score increases of ≈2.1 points; the group using robotics exhibited larger score changes on all but one of the Canadian Occupational Performance Measure and Stroke Impact Scale subscales, including a 12.5-point increase on the Stroke Impact Scale recovery subscale. Findings suggest that therapist-supervised repetitive task-specific practice integrating robotics is as efficacious as manual practice in subjects with moderate upper extremity impairment.

    Sonography is still the method of choice for imaging diseases in pregnant women. The changed physiognomy of the women increases the known limitations of sonography while the advantages of MRI (large field of view, excellent soft-tissue contrast, sensitive diagnosis of edema) are not affected. The available sequences allow the differentiation of various pathologies. Most of these can frequently be visualized without intravenous administration of contrast material. Although the significance of techniques like DWI and ASL has not yet been explored, initial descriptions are promising and MR imaging in pregnancy will be increasingly important in the future. Therefore, knowledge of the most frequent diseases in pregnancy and their image appearance is relevant to radiologists. The advantages of MRI in comparison to sonography and its important role in imaging pathologies of the acute abdomen in pregnancy are illustrated and discussed. (orig.)

    An experimental model in the rabbit is presented which is suitable for analysis of clinically relevant, early side-effects of combined upper abdominal IORT and ERT. Fractionated ERT alone given through an upper abdominal a.-p. field including the entire stomach caused gastric ulcerations within ≤ 58 days. Latent times decreased with increasing dose and the ED 50 for occurrence of ulcers was 39 ± 3.3 Gy. Single doses of IORT of 20-40 Gy alone administered through a 2-cm diameter field localized on the coeliac axis and carefully excluding any intestinal mucosa caused neither gastric ulcerations nor other clinical symptoms. When ERT with 40 Gy was preceded by IORT with 20-40 Gy or by sham IORT, 13 out of 15 animals developed ulcers after latent times which in a life-table analysis were shown to be significantly shorter than after ERT alone. However, a statistically significant IORT dose-dependence of latent time or incidence of ulcers could not be demonstrated in the present experiment. The most significant histological changes were observed in the areas of gastric ulcers. Already during ERT, the mucosal epithelium was depleted and regenerative activity was evident in spite of ongoing fractionated irradiation. However, profound irregularities in glandular structure and distribution, as well as number of proliferating epithelial cells were still present in healed ulcers at 80 days. In summary, IORT to the coeliac artery did precipitate the development of gastric ulcers induced by subsequent ERT. On the one hand, the data indicate that the surgical procedure of IORT did contribute to this effect. On the other hand, IORT to the coeliac artery could cause transient, functional alterations in blood supply to the depending organs, i.e. the stomach, and could thus precipitate the development of radiation-induced ulcers

    Purpose/Objective: A large proportion of patients with stage I, II or III follicular lymphoma remains free of recurrence for a long period of time after a complete response(CR) to the initial treatment. The yield of the costly follow-up tests, especially the CT of the abdomen and pelvis, for this indolent lymphoma has not been systematically studied. Materials and Methods: A total of 328 patients with previously untreated stage I, II or III follicular lymphoma were treated at our institution between 1978 and 1994. Two hundred fifty seven patients achieved CR to treatments: seventy eight of them relapsed. Their median age was 55 years. Their stages were; I-15, II-28, III-35. Their treatments were; radiation therapy-15, chemotherapy-12, combined modality with radiation and chemotherapy-51. The medical records of these 78 patients were reviewed in detail to analyze the yield of the CT of the abdomen and pelvis in detecting the recurrence relative to history/physical exam(H/PE), complete blood count(CBC), serum chemistry, chest roentgenogram(CXR), and KUB to visualize the residual lymphangiogram dye(KUB/LAG). A positive study was defined as one which led to or was abnormal at the time of the diagnosis of recurrence. Results: The median follow-up period was 101 months. Patients were usually followed in the clinic every 3 to 6 months for the initial 5 years and then yearly thereafter. The number of the positive studies per total number of follow-up studies performed in the period between CR and recurrence were; H/PE-55/568, CBC-1/534, serum chemistry-5/517, CXR-6/488, KUB/LAG-13/190, CT of abdomen-29/259, CT of pelvis-19/242. Eleven relapses were detected only by CT of abdomen and pelvis. Conclusion: Fourteen percent ((11(78))) of the relapses were detected solely by CT of the abdomen and pelvis. This implies 4.3 % ((11(257))) of the patients who achieved CR benefited from the CT of the abdomen and pelvis for recurrence detection. The yield of the routine use of the CT

    Full Text Available The glenohumeral joint is the most commonly dislocated joint in the human body. Anterior dislocatin is the most common type and posterior dislocations account for <1% of shoulder dislocations.  A 68-yearold woman was brought to the emergency department by ambulance  with shoulder pain following a fall from stairs. On local physical examination, there was severe pain on the left proximal humerus. The left arm was in internal rotation in the adducted position. Active and passive movements of the left shoulder were painful and limited. The neurovascular examination of the left upper extremity revealed no deficit. Radiographs of her left shoulder were performed and no significant pathology was identified in the left shoulder anteroposterior (AP X-ray (Figure 1. Axillary radiography could not be performed because of painful arm movements. Therefore, CT was performed to clarify any existing shoulder pathology (Figure 2. Closed reduction under conscious sedation was performed with longitudinal and lateral traction on the arm to protect the humeral head. Control CT was performed and this revealed that reduction had improved the shoulder (Figure 3. She was then treated with an arm sling and discharged with an outpatient orthopaedic control visit.

    When the upper arm (area from shoulder to elbow) is inaccessible and/or a standard-sized blood pressure cuff does not fit, some healthcare workers use the forearm to measure blood pressure. To compare automatic noninvasive measurements of blood pressure in the upper arm and forearm. A descriptive, correlational comparison study was conducted in the emergency department of a 1071-bed teaching hospital. Subjects were 204 English-speaking patients 6 to 91 years old in medically stable condition who had entered the department on foot or by wheelchair and who had no exclusions to using their left upper extremity. A Welch Allyn Vital Signs 420 series monitor was used to measure blood pressure in the left upper arm and forearm with the subject seated and the upper arm or forearm at heart level. Pearson r correlation coefficients between measurements in the upper arm and forearm were 0.88 for systolic blood pressure and 0.76 for diastolic blood pressure (P upper arm and forearm differed significantly (t = 2.07, P = .04). A Bland-Altman analysis indicated that the distances between the mean values and the limits of agreement for the 2 sites ranged from 15 mm Hg (mean arterial pressure) to 18.4 mm Hg (systolic pressure). Despite strict attention to correct cuff size and placement of the upper arm or forearm at heart level, measurements of blood pressure obtained noninvasively in the arm and forearm of seated patients in stable condition are not interchangeable.

    Hernia repairs still exhibit clinical complications, i.e. recurrence, discomfort and pain and mesh features are thought to be highly influent. The aim of this study is to evaluate the impact of the defect size and mesh type in an herniated abdominal wall using numerical models. To do so, we have started from a FE model based on a real human abdomen geometry obtained by MRI, where we have provoked an incisional hernia of three different sizes. The surgical procedure was simulated by covering the hernia with a prostheses, and three surgical meshes with distinct mechanical properties were used for the hernia repair: an isotropic heavy-weight mesh (Surgipro @ ), a slightly anisotropic light-weight mesh (Optilene @ ) and a highly anisotropic medium-weight mesh (Infinit @ ). The mechanical response of the wall to a high intraabdominal pressure (corresponding to a coughing motion) was analyzed here. Our findings suggest that the anisotropy of the mesh becomes more relevant with the increase of the defect size. Additionally, according to our results Optilene @ showed the closest deformation to the natural distensibility of the abdomen while Infinit @ should be carefully used due to its excessive compliance.

    BACKGROUND Celiacomesenteric trunk (CMT) is a very rare anatomic finding in which the celiac artery and the superior mesenteric artery (SMA) originate from the abdominal aorta through a common trunk. Clinical associations with CMT include arterial aneurysm, thrombosis, and celiac artery compression. However, an association between CMT and abdominal venous congestion caused by left renal vein compression, or 'nutcracker phenomenon,' has not been previously reported. CASE REPORT A 91-year-old woman, who died from a cerebrovascular accident (CVA), underwent a cadaveric examination at our medical school. On examination of the abdomen, there was an incidental finding of CMT. The arterial and venous diameters were measured, and vascular histopathology was undertaken. The vascular anatomy was consistent with CMT type 1-b. Nutcracker phenomenon (NCP) (left renal vein compression) was seen anatomically as dilatation and engorgement of the left renal vein, relative to the right renal vein (10.77±0.13 mm vs. 4.49±0.56 mm, respectively), and dilatation and engorgement of the left ovarian vein, relative to the right ovarian vein (4.37±0.15 mm vs. 1.06±0.09 mm, respectively) with left ovarian varicocele. The aortoceliac angle (ACA) and the aortomesenteric angle (AMA) approached zero degrees. CONCLUSIONS We have described a rare anatomic finding of CMT that created an acute AMA and NCP. Awareness of this rare association between CMT and NCP by clinicians, vascular surgeons, and radiologists may be of value in the future evaluation and surgical management of patients who present clinically with 'nutcracker syndrome.'

    Purpose: The aim of this work was to reduce the influence of motion on diffusion-weighted MR images of the abdomen by pulse triggering of single-shot sequences. Methods: Five healthy volunteers were examined both without and with finger pulse-triggering of a diffusion-weighted single-shot echo planar MR imaging sequence at 1.5 T. Series of diffusion-weighted images were acquired at different phases of the cardiac cycle by varying the time delay between finger pulse and sequence acquisition. The measurements were repeated three times. The diffusion weighted images were analysed by measuring the signal intensities and by determining the ADC values within the spleen, kidney and liver. Results: The magnitude of motion artifacts on diffusion weighted images shows a strong dependence on the trigger delay. The optimum trigger delay is found to be between 500 and 600 ms. For these values the abdominal organs appear homogeneous on all diffusion weighted images and the strongest signal intensities are detected. At optimum triggering the accuracy of the apparent diffusion coefficients is up to 10 times better than without triggering. Moreover, the standard deviation of the repeated measurements is smaller than 12% for all volunteers and for all organs. Without triggering the standard deviation is larger by a factor of 4 on average. Conclusion: Pulse triggering of single-shot sequences leads to significant reduction of motion related artifacts on diffusion weighted images of the abdomen and provides more accurate and reproducible ADC values.

    Full Text Available Adult tethered cord syndrome (ATCS is a rare entity that usually presents with multiple neurological symptoms, including lower extremity pain, backache, lower extremity muscle weakness, and bowel/bladder disturbances. Prompt surgical treatment is often necessary to avoid permanent sequelae. We report a 63-year-old man with sudden-onset severe right chest and upper back pain, followed by urinary retention. His initial workup included computed tomography of the abdomen and pelvis, which showed a presacral mass. His symptom-driven neurological workup focused on the cervical and thoracic spine, the results of which were normal. Pelvic radiographs and magnetic resonance imaging of the lumbosacral spine showed spina bifida occulta, meningocele, and presacral masses consistent with a teratomatous tumor. His symptoms, except for urinary retention, improved dramatically with surgical treatment. The excised specimen contained a teratomatous lesion plus an organized hematoma. Hematoma formation was suspected as the trigger of his sudden-onset right chest and upper back pain.

    Full Text Available A 60-year-old male patient was admitted to our hospital for recurrent upper quadrant pain for 1 month. He had a past history of coronary artery disease. After admission, he repeatedly suffered from high-grade fever, chills and upper quadrant pain. Computed tomography (CT showed a round hypodense mass in the left lobe of the liver, approximately 2.7 × 2.2 cm in size, and a fish bone was confirmed by surgery in the left lobe of liver. The patient was cured completely after surgical removal of the fish bone and liver abscess. CT scan 1 month after discharge showed that the liver abscess had disappeared completely.

    This study aimed to evaluate the left ventricular (LV) functions in a cohort of children with Graves' disease (GD). This is a cross-sectional case-control study. It included 36 children with GD and 36 healthy children matched for age and gender. Thyroid hormones (TSH, FT4, and FT3) and anti-thyroid autoantibodies [anti-thyroid peroxidase (anti-TPO), thyrotropin receptor (TRAbs), and thyroglobulin antibodies] were measured. Conventional and tissue Doppler imaging (TDI) echocardiographies were used to assess left ventricular systolic and diastolic functions. LV mass index (LVMI) and myocardial performance index (MPI) were also measured. Compared to healthy children, conventional echocardiography of patients with GD revealed higher LVMI (P = 0.001) indicating LV hypertrophy but normal LV functions while TDI revealed lower Em/Am ratio indicating LV diastolic dysfunction (P = 0.001). Significant correlations were reported between FT4 with LVMI (P = 0.05), Em/Am (P = 0.01), and MPI (P = 0.01). In multivariate analysis, a positive correlation was identified between FT4 with MPI (OR = 1.17; 95% CI = 1.09-1.15; P = 0.001). Children with newly diagnosed GD may have significant subclinical changes in LV structure and function (diastolic and global). TDI is more sensitive than conventional Doppler in detecting LV dysfunction. These findings highlight the importance of early monitoring of children with GD for left ventricular mass index and diastolic function. What is Known: • There is an increased risk for cardiac abnormalities in children with Graves' disease (GD). • Limited studies assessed left ventricular function in patients with GD. What is New: • Children with newly diagnosed GD may have significant subclinical changes in left ventricular structure and functions. • Children with newly diagnosed GD should be monitored for left ventricular mass index and diastolic function.

    2010-01-01

    The term ''acute abdomen'' does not describe a specific disease entity but is more a critical clinical state which incorporates very heterogeneous clinical presentations. The prognosis of any disease depends on the time frame from the onset of symptoms to the initiation of a specific therapy. For this reason there are special expectations by clinicians regarding the diagnostic assessment provided by radiology which is expected to deliver an immediate diagnosis supporting further therapeutic decisions. Along with the patient's clinical history, physical examination and blood tests, radiological diagnostics are essential for enabling a specific treatment. From a surgical point of view the radiologist is expected to help in differentiating between cases with indications for emergency surgery and cases eligible for elective surgery or conservative treatment.

    2010-06-01

    This review comments on epidemiology, diagnosis and general principles of surgical management in patients with acute abdomen. DEFINITION AND EPIDEMIOLOGY: The most common cause of acute abdominal pain is non-specific abdominal pain (24 - 44.3 % of the study populations), followed by acute appendicitis (15.9 - 28.1 %), acute biliary disease (2.9 - 9.7 %) and bowel obstruction or diverticulitits in elderly patients. Acute appendicitis represents the cause of surgical intervention in two-thirds of the children with acute abdomen. A standardised physical examination combined with ultrasonography (US) represents the initial investigation in patients with acute abdominal pain. Due to the risk associated with radiation and due to the costs, a selective use of CT imaging is recommended. The work-flow given in this paper restricts the use of CT imaging to less than 50 % of patients with acute abdominal pain. Diagnostic laparoscopy should be considered in patients without a specific diagnosis after appropriate imaging and as an alternative to active clinical observation which is the current practice in patients with non-specific abdominal pain. Acute small bowel obstruction has previously been considered as a relative contraindication for laparoscopic management, but it has been shown in the meantime that laparoscopic treatment is an elegant tool for the management of simple band small bowel obstruction. Bedside diagnostic laparoscopy is recommended in intensive care unit (ICU) patients with acute abdomen or sepsis of unknown origin, in suspicion of acute cholecystitis, diffuse gut hypoperfusion and mesenteric ischaemia or in refractory lactic acidosis, especially after cardiac surgery. Early administration of analgesia to patients with acute abdominal pain in the emergency department will reduce the patient's discomfort without impairing clinically important diagnostic accuracy and is recommended on the basis of some prospective randomised trials. However, the impact on

    Enterocutaneous fistula (ECF), enteroatmospheric fistula (EAF), and intra-abdominal sepsis/abscess (IAS) are major challenges for surgeons caring for patients undergoing damage control laparotomy after trauma. To determine independent predictors of ECF, EAF, or IAS in patients undergoing damage control laparotomy after trauma, using the AAST Open Abdomen Registry. The AAST Open Abdomen registry of patients with an open abdomen following damage control laparotomy was used to identify patients who developed ECF, EAF, or IAS and to compare these patients with those without these complications. Univariate analyses were performed to compare these groups of patients. Variables from univariate analyses differing at P IAS. Fourteen level I trauma centers. A total of 517 patients with an open abdomen following damage control laparotomy. Complication of ECF, EAF, or IAS. More patients in the ECF/EAF/IAS group than in the group without these complications underwent bowel resection (63 of 111 patients [57%] vs 133 of 406 patients [33%]; P 48 hours after surgery, the ECF/EAF/IAS group received more colloids (P IAS group underwent almost twice as many abdominal reexplorations as did the group without these complications (mean [SD] number, 4.1 [4.1] vs 2.2 [3.4]; P IAS were a large bowel resection (adjusted odds ratio [AOR], 3.56 [95% CI, 1.88-6.76]; P 48 hours of between 5 and 10 L (AOR, 2.11 [95% CI, 1.15-3.88]; P = .02) or more than 10 L (AOR, 1.93 [95% CI, 1.04-3.57]; P = .04), and an increasing number of reexplorations (AOR, 1.14 [95% CI, 1.06-1.21]; P IAS in patients with an open abdomen after damage control laparotomy.

    Full Text Available We describe the case of a 30-year-old patient with bilateral mature cystic teratoma (MCT of the ovaries. The patient had been complaining of mild abdominal pain for several months that had suddenly become severe. Early diagnosis at the emergency room was acute appendicitis, but definitive diagnosis was bilateral ovarian teratoma. We therefore recommend considering ovarian teratomas in the differential diagnosis of acute abdomen in young women in an emergency care setting.

  15. Effects of upper-limb immobilisation on driving safety.

    Doctors are frequently asked by patients whether it is safe to drive with an upper limb immobilised in a cast. In the literature there are no objective measurements of the effects of upper-limb immobilisation upon driving performance. Eight healthy volunteers performed four 20-min driving circuits in a driving simulator (STISIM 400W), circuits 1 and 4 without immobilisation and circuits 2 and 3 with immobilisation. Immobilisation involved a lightweight below-elbow cast with the thumb left free. Volunteers were randomised to right or left immobilisation for circuit 2, and the contralateral wrist was immobilised for circuit 3. Circuits included urban and rural environments and specific hazards (pedestrians crossing, vehicles emerging from a concealed entrance, traffic lights changing suddenly, avoidance of an oncoming vehicle in the driver's carriageway). Limb immobilisation led to more cautious rural and urban driving, with less adjustment of speed and lateral road position than when unrestricted. However when responding to hazards immobilisation caused less safe driving, with higher speeds, a greater proximity to the hazard before action was taken and less steering adjustment. The effects of restriction upon performance were more prevalent and severe with right-arm immobilisation. Upper-limb immobilisation appears to have little effect on the ability to drive a car unchallenged, but to adversely affect responses to routine hazards. Advice on ability to drive safely should be cautious, as the impact of immobilisation appears to be more subtle and wide ranging than previously thought.

    2017-01-01

    Full Text Available A 2-year-old boy with prune-belly syndrome and severe pectus excavatum experienced recurrent pulmonary infections. A CT scan of the chest demonstrated compression of the left mainstem bronchus and leftward shift of the heart. The bronchial compression resulted in left upper lobe collapse and left lower lobe air-trapping requiring two hospitalizations for respiratory distress and pneumonia. The child underwent minimally invasive repair of his pectus excavatum and has not experienced any further pulmonary events. The pectus bar was removed 3 years post-operatively and at seven years following surgery he has a sustained repair.

    Full Text Available Stroke is a leading cause of disability worldwide. In this paper, a novel robot-assisted rehabilitation system based on motor imagery electroencephalography (EEG is developed for regular training of neurological rehabilitation for upper limb stroke patients. Firstly, three-dimensional animation was used to guide the patient image the upper limb movement and EEG signals were acquired by EEG amplifier. Secondly, eigenvectors were extracted by harmonic wavelet transform (HWT and linear discriminant analysis (LDA classifier was utilized to classify the pattern of the left and right upper limb motor imagery EEG signals. Finally, PC triggered the upper limb rehabilitation robot to perform motor therapy and gave the virtual feedback. Using this robot-assisted upper limb rehabilitation system, the patient's EEG of upper limb movement imagination is translated to control rehabilitation robot directly. Consequently, the proposed rehabilitation system can fully explore the patient's motivation and attention and directly facilitate upper limb post-stroke rehabilitation therapy. Experimental results on unimpaired participants were presented to demonstrate the feasibility of the rehabilitation system. Combining robot-assisted training with motor imagery-based BCI will make future rehabilitation therapy more effective. Clinical testing is still required for further proving this assumption.

    Lateral impact tests were performed using seven male post-mortem human subjects (PMHS) to characterize the force-deflection response of contacted body regions, including the lower abdomen. All tests were performed using a dual-sled, side-impact test facility. A segmented impactor was mounted on a sled that was pneumatically accelerated into a second, initially stationary sled on which a subject was seated facing perpendicular to the direction of impact. Positions of impactor segments were adjusted for each subject so that forces applied to different anatomic regions, including thorax, abdomen, greater trochanter, iliac wing, and thigh, could be independently measured on each PMHS. The impactor contact surfaces were located in the same vertical plane, except that the abdomen plate was offset 5.1 cm towards the subject. The masses of the sleds and the force- deflection characteristics of the energy-absorbing interface material between the sleds were set to provide the impactor sled with a velocity profile that matched the average driver door velocity history produced in a series of side NCAP tests. Impactor padding was also selected so that average ATD pelvis and thorax responses from the same series of side NCAP tests were reproduced when the ATD used in these tests was impacted using the average door-velocity history. Each subject was first impacted on one side of the body using an initial impactor speed of 3 m/s. If a post-test CT scan and strain-gage data revealed two or fewer non-displaced rib fractures, then the PMHS was impacted on the contralateral side of the body at a speed of 8 m/s or 10 m/s. The results of tests in the 3 m/s and 8 m/s conditions were used to develop force-deflection response corridors for the abdomen, force history response corridors for the pelvis (iliac wing and greater trochanter), the midthigh, and the thorax. Response corridors for the lateral acceleration of the pelvis were also developed. Future work will compare side impact ATD

    We report the case of an immunocompromised 15-year-old boy who presented with symptoms mimicking an ''acute abdomen'' related to necrotizing myofasciitis of the anterior abdominal wall. CT demonstrated the abdominal wall process as the cause of the patient's symptoms and sonographically guided aspiration confirmed the diagnosis. Despite prompt diagnosis and aggressive surgical debridement, the infection continued to progress and the patient died within 24 h of presentation. (orig.)

    The acute abdomen accounts for up to 40% of all emergency surgical hospital admissions and a large proportion are secondary to gastrointestinal perforation. Studies have shown the superiority of the abdominal CT over upright chest radiographs in demonstrating free intraperitoneal air. Spontaneous perforated pyometra is a rare cause of the surgical acute abdomen with free intraperitoneal air. Only 38 cases have been reported worldwide. We report 2 cases of spontaneously perforated pyometra in our hospital's general surgery department. Both underwent exploratory laparotomy: one had a total hysterectomy and bilateral salpingo-oophorectomy, while the other had an evacuation of the uterine cavity, primary repair of uterine perforation and a peritoneal washout. A literature search was conducted and all reported cases reviewed in order to describe the clinical presentations and management of the condition. Of the 40 cases to date, including 2 of our cases, the most common presenting symptoms were abdominal pain (97.5%), fever (37.5%) and vomiting (25.0%). The main indication for exploratory laparotomy was pneumoperitoneum (97.5%). Pyometra is an unusual but serious condition in elderly women presenting with an acute abdomen. A high index of suspicion is needed to make the appropriate diagnosis.

    Full text: A 78-year-old female patient was suffering from dyspnoea and tachypnoea in our hospital's orthopaedic clinic. Because she had an operation of right femoral mid-diaphizer fracture a week ago, we decided to perform a pulmonary computerized tomography angiography (CTA) examination with her clinicians in order to evaluate a possible pulmonary embolism and to make a further evaluation. In her CTA exam there were no pulmonary embolism was seen. There were some chronic changes in her lungs, bilateral pleural effusion and hilar lymphadenomagalies. A dilated and tortiozed vascular structure which was retrocrural and retroaortic placed at the level of the thorachoabdominal transition and joined to left brachiocephalic vein was seen. Then we realized that the liver was symmetrical and transverse localization the upper abdomen and the stomach and spleen was in the right upper quadrant. Because the cardiac apex was left-sided we decided that a kind of situs ambiguous. After that the patient was underwent a abdominal contrast enhanced CT which was including the both arterial and venous phases. In this examination the suprarenal part of the inferior vena cava (IVC) was interrupted and it was continuing as hemiazygos vein to the thorax something like the previous CT exam. The hepatic veins were drained into a short segment vein and then the right atrium. Multiple nodular parenchymal images which were enhanced like spleen in all phases were seen in right upper quadrant of the abdomen (polysplenia). And also partial agenesis of the pancreas and annular pancreas configuration was seen. Anomalies of the IVC occur rarely and the patient are usually asymptomatic. Non-invasive imaging modalities such as CT and MRI allow better identification of these anomalies. In these cases different organ anomalies accompanies the IVC anomalies

    Background and Aim Diagnosis of typhoid is challenging when blood cultures fail to isolate Salmonella species. We report our experience with interpreting computed tomography (CT) abdomen findings in a case series of typhoid fever. Methods The case series consisted of patients who had a CT abdomen done as part of their investigations and a final diagnosis of typhoid fever. The CT films were reviewed and findings evaluated for distinctive features. Results During 2011-2017, 11 patients met the inclusion criteria. Indication for CT was pyrexia of unknown origin in the majority of patients. Review of CT films revealed mesenteric lymphadenopathy (100%), terminal ileum thickening (85%), hepatosplenomegaly (45%), retroperitoneal lymphadenopathy (18%) and ascites (9%). Conclusions Enhancing discrete mesenteric lymphadenopathy and terminal ileum thickening are non-specific findings noted in typhoid fever. Absence of matted necrotic nodes and peritoneal thickening rule out tuberculosis and raise suspicion of typhoid fever in endemic regions.

  4. An Experience of an Individual With a Chronic Wound in an Open Abdomen: A Grounded Theory.

    2017-06-01

    The open abdomen (OA) surgical technique has become an option for treating complex abdominal injuries; however, complications leading to late closure conditions might arise. In these cases the wound must be left open, which greatly impacts the patient's life. The author aims to describe the experiences of individuals with a chronic OA wound. Qualitative design using grounded theory was utilized. This study was carried out with a group of 28 adults who were treated with OA technique and whose wound had remained open for more than a month in duration and only received outpatient wound care. Data were collected through open interviews and examined under continuous comparison. The average age of the respondents was 45 years, and their wound, treated with OA due to severe abdominal infection, remained open between 2 months and 8 years. An emergent theory was developed to describe how people facing this experience undergo a process of 4 stages: 1) finding an OA wound upon waking, 2) feeling desperate about the healing process and the limitations involved, 3) regaining control of their life, and 4) taking advantage of their second chance at life with an OA wound. This study provides insight for nurses and other health care professionals into the experiences of patients with a chronic OA wound and proposes an emerging theory based on the conceptualization of these experiences.

    Full Text Available Abstract Background Penetrating injuries of the abdomen and spinal canal that involve organic material of animal origin are extremely rare and derive from domestic and wild animal attacks or fish attacks. Case presentation In this case report we present the unique, as far as the literature is concerned, unprovoked woman's injury to the abdomen by a swordfish. There are only four cases of swordfish attacks on humans in the literature - one resulted to thoracic trauma, two to head trauma and one to knee trauma, one of which was fatal - none of which were unprovoked. Three victims were professional or amateur fishermen whereas in the last reported case the victim was a bather as in our case. Our case is the only case where organic debris of animal's origin remained in the spinal canal after penetrating trauma. Conclusions Although much has been written about the management of penetrating abdominal and spinal cord trauma, controversy remains about the optimal management. Moreover, there is little experience in the management of patients with such spinal injuries, due to the fact that such cases are extremely rare. In this report we focus on the patient's treatment with regard to abdominal and spinal trauma and present a review of the literature.

    Antegrade continence enemas (ACE) are an efficacious therapeutic option for patients with fecal incontinence. The authors review their institution's experience with a variation of the Monti-Malone ACE procedure using the left colon as a source of an intestinal conduit and enema reservoir. From 2000 to 2002, 18 patients with fecal incontinence or intractable constipation underwent left-colon ACE (LACE) procedure. Concomitant Mitrofanoff appendicovesicostomy was performed in 15 patients and bladder augmentation in 9. The majority of patients had neural tube defects. A segment of left colon was tubularized, tunneled into the muscular wall of the distal colon, and exteriorized through the left upper quadrant or midabdomen. Stomal catherization and enema installation were started one month postoperatively. Fifteen patients (83%) achieved fecal continence, 2 remain incontinent of stool, and 1 experienced stomal closure (mean follow-up was 24 +/- 9 months). Two patients had stomal stenosis that required revision. The mean enema volume in patient's achieving continence was 360 +/- 216 mL, and the mean transit time was 18 +/- 12 minutes. LACE is an efficacious procedure for fecal incontinence that can be performed safely at the time of major urologic reconstruction. Administration of enemas into the left colon has several physiologic advantages that result in predictable bowel evacuation.

    Four Tc-99 radiopharmaceuticals, Tc-99m sulphur colloid, Tc-99m red blood cells (RBCs), Tc-99m mercaptoacetyltriglycine (MAG3), and Tc-99m DTPA, were studied in an experimental animal model for detection and localization of gastrointestinal (GI) bleeding site in both the upper and lower abdomen. With Tc-99m sulphur colloid and Tc-99m RBCs, it was possible to detect and localize the GI bleeding site in the lower abdomen. With Tc-99m MAG3, it was possible to visualize the bleeding site in both the upper and lower abdomen. However, Tc-99m MAG3 is partially excreted by the liver into the bile, hence it will be difficult to use Tc-99m MAG3 to localize the GI bleeding site in the lower abdomen. With Tc-99m DTPA, it was possible to detect and localize the GI bleeding site simultaneously in both upper and lower abdomen. The overall background radioactivity was reduced considerably by diuresis with frusemide and catheterization of the urinary bladder

    Varied clinical presentations of Penicillium marneffei , an opportunistic pathogen in HIV disease has been rarely described in literature. We report a patient with advanced AIDS who presented to us with prolonged fever and had features of an acute abdomen. On radiologic imaging he had features of intestinal obstruction and mesenteric lymphadenitis. A diagnosis was made possible by endoscopic biopsies of the small bowel and bone marrow culture which grew P . Marneffei . He was treated with ...

    Full Text Available We report a patient with lung cancer. The first PET/CT imaging revealed hypermetabolic mass in the left aortopulmonary region and hypermetabolic nodule in the anterior segment of the upper lobe of the left lung. After completing chemotherapy and radiotherapy against the primary mass in the left lung, the patient underwent a second PET/CT examination for evaluation of treatment response. This test demonstrated, compared with the first PET/CT, an increase in the size and metabolic activity of the primary mass in the left lung in addition to multiple, pathologic-sized, hypermetabolic metastatic lymph nodes as well as multiple metastatic sclerotic areas in bones. These findings were interpreted as progressive disease. In addition, an asymmetrical FDG uptake was noticed at the level of right vocal cord. During follow-up, a laryngoscopy was performed, which demonstrated left vocal cord paralysis with no apparent mass. Thus, we attributed the paralytic appearance of the left vocal cord to infiltration of the left recurrent laryngeal nerve by the primary mass located in the apical region of the left lung. In conclusion, the knowledge of this pitfall is important to avoid false-positive PET results.

    This paper reports the management of two clinical cases, in which the upper right central incisor was fused with a supernumerary tooth and the upper left central incisor was macrodontic. A radiographic examination revealed that the fused teeth had two separate roots. Hemisectioning of the fused teeth was performed, the supernumerary portion was extracted and the remaining part was reshaped to remove any sharp margins and to achieve a normal morphology. The macrodontic central incisors were not treated. At 12-months post-surgery there were no periodontal problems and no hypersensitivity. Orthodontic treatment was performed to appropriately align the maxillary teeth and to correct the malocclusion.

    Forty patients with suspected pathology in the abdomen and pelvis have been investigated with MRI before and after administration of Gd-DTPA as an oral or rectal solution. The findings are analysed with respect to: (a) filling of the GI tract; (b) contrast in the region of interest, surrounding fat and vessels; (c) diagnostic yield in comparison to non-enhanced MRI and contrast CT. At a concentration of 1 mmol/l Gd-DTPA provided consistent positive contrast in the stomach and bowel in all cases. In 57.5% of cases we achieved complete filling of the GI tract. The opacification in the region of interest was good or satisfactory in 90% of cases. The diagnostic value of contrast MRI was better in 93% of cases than the non-enhanced MRI of the abdomen. In comparison with contrast CT, the contrast MRI was better or of the same value in 92% of cases. Despite the disadvantage of poor fat-to-bowel contrast (35% of cases were classified as poor), it is concluded that Gd-DTPA-enhanced MRI provides good delineation of organs adjacent to the bowel so this contrast agent has potential for a future role in abdominal MRI.

    1993-01-01

    The purpose of this study was to produce a comprehensive anatomic atlas of CT anatomy of the dog for use by veterinary radiologists, clinicians, and surgeons. Whole-body CT images of two mature beagle dogs were made with the dogs supported in sternal recumbency and using a slice thickness of 13 mm. At the end of the CT session, each dog was euthanized, and while carefully maintaining the same position, the body was frozen. The body was then sectioned at 13-mm intervals, with the cuts matched as closely as possible to the CT slices. The frozen sections were cleaned, photographed, and radiographed using xeroradiography. Each CT image was studied and compared with its corresponding xeroradiograph and anatomic section to assist in the accurate identification of specific structures. Clinically relevant anatomic structures were identified and labeled in the three corresponding photographs (CT image, xeroradiograph, and anatomic section). In previous papers, the head and neck, and the thorax and cranial abdomen of the mesaticephalic (beagle) dog were presented. In this paper, the caudal part of the abdomen and pelvis of the bitch and male dog are presented

    A 12-year-old boy reported in outpatient department with history of shortness of breath and dyspnoea on moderate exertion. Physical examination was significant for bounding pulses and for a continuous murmur III/VI, best heard at the left upper sternal border. Echocardiography confirmed a large patent arterial duct with shortening fraction of 33%. He underwent successful transcatheter closure of the patent arterial, using Amplatzer duct occluder 12/10. Few hours later echocardiography revealed an unexpected, yet important depression of left ventricular systolic function with shortening fraction decreasing to 24% and then two weeks later decreasing further to 20%. At a follow-up after four months, he had improved clinically but left ventricular dysfunction still persisted with shortening fraction of 24%.

    Torsion of the omentum is twisting along its long axis and a rare cause of acute abdomen. Depending on associated conditions, it is classified as primary and secondary. It may mimic different pathologies presenting as acute abdomen, most common of them being acute appendicitis. Current choice for management of omental torsion is laparoscopic surgery. We present two cases of omental torsion of two boys who presented with abdominal pain, nausea and vomiting and underwent emergency laparoscopy. Omental torsion is very rare, and its diagnosis is usually made only after surgery. At laparoscopy, omental torsion is suspected when the appendix is normal and the symptoms and findings of torsion are present. Laparoscopy is a safe and effective approach for the diagnosis and management of omental torsion, with the advantages of reduced postoperative pain and hospital stay. © The Author(s) 2015.

    The aim of this clinical study was to compare the image quality of digital radiography using the new digital Bucky system based on a flat-panel detector with that of a conventional screen-film system for the skeletal structure and the abdomen. Fifty patients were examined using digital radiography with a flat-panel detector and screen-film systems, 25 for the skeletal structures and 25 for the abdomen. Six radiologists judged each paired image acquired under the same exposure parameters concerning three observation items for the bone and six items for the abdomen. Digital radiographic images for the bone were evaluated to be similar to screen-film images at the mean of 42.2%, to be superior at 50.2%, and to be inferior at 7.6%. Digital radiographic images for the abdomen were judged to be similar to screen-film images at the mean of 43.4%, superior at 52.4%, and inferior at 4.2%; thus, digital radiographic images were estimated to be either similar as or superior to screen-film images at over 92% for the bone and abdomen. On the statistical analysis, digital radiographic images were also judged to be preferred significantly in the most items for the bone and abdomen. In conclusion, the image quality of digital radiography with a flat-panel detector was superior to that of a screen-film system under the same exposure parameters, suggesting that dose reduction is possible with digital radiography.

    Full Text Available Stroke is a leading cause of disability worldwide. In this paper, a novel robot‐assisted rehabilitation system based on motor imagery electroencephalography (EEG is developed for regular training of neurological rehabilitation for upper limb stroke patients. Firstly, three‐dimensional animation was used to guide the patient image the upper limb movement and EEG signals were acquired by EEG amplifier. Secondly, eigenvectors were extracted by harmonic wavelet transform (HWT and linear discriminant analysis (LDA classifier was utilized to classify the pattern of the left and right upper limb motor imagery EEG signals. Finally, PC triggered the upper limb rehabilitation robot to perform motor therapy and gave the virtual feedback. Using this robot‐assisted upper limb rehabilitation system, the patientʹs EEG of upper limb movement imagination is translated to control rehabilitation robot directly. Consequently, the proposed rehabilitation system can fully explore the patientʹs motivation and attention and directly facilitate upper limb post‐stroke rehabilitation therapy. Experimental results on unimpaired participants were presented to demonstrate the feasibility of the rehabilitation system. Combining robot‐assisted training with motor imagery‐ based BCI will make future rehabilitation therapy more effective. Clinical testing is still required for further proving this assumption.

    A lady aged 26 years reported with a 2 months history of fever, upper abdominal pain and weight loss. Her abdominal ultrasonographic scan revealed a complex cystic mass in left lobe of liver suggestive of hydatid cyst that was confirmed on magnetic resonance imaging of abdomen and magnetic resonance cholangiopancreatogram. With strong suspicion of a hydatid cyst, endoscopic retrograde cholangiogram was performed which confirmed the diagnosis. During the procedure, hydatid membranes protruding from the papilla were removed after sphincterotomy. She was put on albendazole 400 mg twice daily after the procedure and showed a remarkable clinical improvement. (author)

    This paper presents an estimate of the effective dose from CTDI vol for exams of skull and abdomen in adult patients. Thereafter, measurements were taken of CTDI using an ionization chamber type pencil (Radcal Corportation, model 10 x 5 - 3CT) and cylindrical phantom of PMMA equivalent to regions of the skull (diameter = 16 cm) and abdomen (diameter = 32 cm). The results of effective dose for abdomen varied between 7,3 and 12,1 mSv and for skull between 1,4 and 5,0 mSv. Comparing with the literature data, for abdomen exams between 5 and 7 mSV and skull exams between 1 and 2 mSv, it is shown that it is possible to optimize these protocols, aiming to reduce the doses to patients

    Full Text Available Hepatosplenic abscess caused by Actinomyces is rare and often misdiagnosed as malignancy. Herein, we report a case of hepatosplenic actinomycosis in a 37-year-old immunocompetent man with a 2-month clinical history of intermittent fever and upper left abdominal pain. Physical examination revealed a mildly ill-appearing man with a low-grade fever (38°C and upper left quadrant abdominal tenderness. Abdominal sonographic examination showed the presence of a 6.3 cm × 6.5 cm heterogeneous abscess with a hypoechoic center and honeycomb appearance in an enlarged spleen (8 cm × 5 cm. Computerized tomography of the abdomen revealed a multiloculated splenic lesion, and laparotomy showed multiple hepatic nodules and a splenic abscess. Histopathological examination of the biopsy revealed filamentous branching bacilli and sulfur granules in the hepatosplenic abscess. The patient successfully underwent splenectomy accompanied by intravenous and oral penicillin treatment. Proper and prompt diagnosis of hepatosplenic actinomycosis is important because the therapeutic plan and prognosis of this pathogen are quite different from other microorganisms and malignancies.

    Cystic lymphangioma of the small bowel mesentery is a rare clinical entity, especially after childhood. Medical literature reveals a limited number of such cases presenting as acute abdomen due to bowel obstruction, small bowel volvulus and bleeding into the tumour. We present the management experience of an 18-year-old woman who presented with rapid onset diffuse peritonism and raised inflammatory markers. Computed tomography showed a mass in the small bowel mesentery with suspicion of segmental bowel ischaemia. Emergency laparotomy revealed a mass in the mid-jejunal mesentery close to the bowel wall with no bowel ischaemia. The patient made an uncomplicated recovery after segmental bowel resection and end-to-end anastomosis. Histology confirmed the mass as a cystic lymphangioma involving the jejunal mesentery and two small jejunal polyps. Lymphangioma could be considered in the differential diagnosis of an acute abdomen in a young adult when the presentation is atypical.

    A study was conducted to investigate the effect of load on upper limb muscles and brain activities in light assembly task. The task was conducted at two levels of load (Low and high). Surface electromyography (EMG) was used to measure upper limb muscle activities of twenty subjects. Electroencephalography (EEG) was simultaneously recorded with EMG to record brain activities from Fz, Pz, O1 and O2 channels. The EMG Mean Power Frequency (MPF) of the right brachioradialis and the left upper trapezius activities were higher on the high-load task compared to low-load task. The EMG MPF values also decrease as time increases, that reflects muscle fatigue. Mean power of the EEG alpha bands for the Fz-Pz channels were found to be higher on the high-load task compared to low-load task, while for the O1-O2 channels, they were higher on the low-load task than on the high-load task. These results indicated that the load levels effect the upper limb muscle and brain activities. The high-load task will increase muscle activities on the right brachioradialis and the left upper tapezius muscles, and will increase the awareness and motivation of the subjects. Whilst the low-load task can generate drowsiness earlier. It signified that the longer the time and the more heavy of the task, the subjects will be more fatigue physically and mentally.

    ICRP 103 specifies reference dose levels to be used during radiographic exams. Usually, the radiographer qualitative determines the best radiographic technique (kV and mAs) in order to obtain better image quality with the lowest dose. The objective of this study was to evaluate the doses used in examination of the chest, abdomen and skull in patients of different physical sizes, and infer about the amount of dose required to maintain acceptable radiological contrast in patients of different physical sizes. Techniques used by experienced radiographers of HC-FMB-UNESP for examinations of the chest (PA), abdomen (AP) and skull (AP) for patients of different thickness (small, medium and thick body) were obtained. Dose measurements were performed referring to all kV/mAs combinations. PMMA phantoms were placed below the ionization chamber. The Signal Difference Noise Ratio (SDNR) of the images of the phantoms were calculated from an area of contrast and a region of normal tissue. The Figure of Merit (FoM) was calculated for each of the exam modality. Measured FoM decreased according to the thickness of the chest and abdomen, indicating the need to increase the dose level to maintain the same level of image contrast. Patients thicker usually end up getting more than twice the dose of lean patients. Required image quality levels for correct diagnosis should be obtained using dose levels as low as reasonably practicable examination. These factors highlight the need for a program of quality assurance and effective dose studies in actual service. (author)

    A part of damage-control laparotomy is to leave the fascial edges and the skin open to avoid abdominal compartment syndrome and allow further explorations. This condition, known as open abdomen (OA), although effective, is associated with severe complications. Our aim was to develop evidence-based recommendations to define indications for OA, techniques for temporary abdominal closure, management of enteric fistulas, and methods of definitive wall closure. The literature from 1990 to 2014 was systematically screened according to PRISMA [Preferred Reporting Items for Systematic Reviews and Meta-analyses] protocol. Seventy-six articles were reviewed by a panel of experts to assign grade of recommendations (GoR) and level of evidence (LoE) using the GRADE [Grading of Recommendations Assessment, Development, and Evaluation] system, and an international consensus conference was held. OA in trauma is indicated at the end of damage-control laparotomy, in the presence of visceral swelling, for a second look in vascular injuries or gross contamination, in the case of abdominal wall loss, and if medical treatment of abdominal compartment syndrome has failed (GoR B, LoE II). Negative-pressure wound therapy is the recommended temporary abdominal closure technique to drain peritoneal fluid, improve nursing, and prevent fascial retraction (GoR B, LoE I). Lack of OA closure within 8 days (GoR C, LoE II), bowel injuries, high-volume replacement, and use of polypropylene mesh over the bowel (GoR C, LoE I) are risk factors for frozen abdomen and fistula formation. Negative-pressure wound therapy allows to isolate the fistula and protect the surrounding tissues from spillage until granulation (GoR C, LoE II). Correction of fistula is performed after 6 months to 12 months. Definitive closure of OA has to be obtained early (GoR C, LoE I) with direct suture, traction devices, component separation with or without mesh. Biologic meshes are an option for wall reinforcement if bacterial

    In a previous study, we investigated the contribution of the surface of the face, chest, abdomen, and thigh to thermal comfort by applying local temperature stimulation during whole-body exposure to mild heat or cold. In hot conditions, humans prefer a cool face, and in cold they prefer a warm abdomen. In this study, we extended investigation of regional differences in thermal comfort to the neck, hand, soles, abdomen (Experiment 1), the upper and lower back, upper arm, and abdomen (Experiment 2). The methodology was similar to that used in the previous study. To compare the results of each experiment, we utilized the abdomen as the reference area in these experiments. Thermal comfort feelings were not particularly strong for the limbs and extremities, in spite of the fact that changes in skin temperature induced by local temperature stimulation of the limbs and extremities were always larger than changes that were induced in the more proximal body parts. For the trunk areas, a significant difference in thermal comfort was not observed among the abdomen, and upper and lower back. An exception involved local cooling during whole-body mild cold exposure, wherein the most dominant preference was for a warmer temperature of the abdomen. As for the neck and abdomen, clear differences were observed during local cooling, while no significant difference was observed during local warming. We combined the results for the current and the previous study, and characterized regional differences in thermal comfort and thermal preference for the whole-body surface.

    A 49 year-old man with a past medical history significant for essential hypertension, hyperlipidemia, and coronary artery disease status post percutaneous coronary intervention and stent placement in the right coronary artery in 2010 presented for evaluation of left hemiplegia. He was feeling well until three hours prior to presentation, at which time he fell while walking from his bedroom into the kitchen. After falling, he noticed that his left upper and lower extremities felt weak. He denied any symptoms preceding the fall or any loss of consciousness. On initial exam, the temperature was 99°F, the pulse was 93 beats per minute, the blood pressure was 191/100 mmHg, the respiratory rate was 22 breaths per minute, and the oxygen saturation was 100% while breathing room air. His neurological exam revealed diminished strength in the left upper extremity: 4/5 arm abduction and adduction of the left shoulder; 4/5 elbow and wrist extension and flexion; and 4/5 extension, abduction, and adduction of the digits. The patient also exhibited slight left upper extremity pronator drift. The strength was also diminished in the left lower extremity: 2/5 hip flexion, extension, and rotation; 3/5 knee flexion and extension; and 3/5 ankle dorsiflexion and plantar flexion. Initial NIH stroke scale score was 5, otherwise, there were no focal neurological deficits and the remainder of his exam was unremarkable. Initial computed tomography (CT) of the head was negative for any acute intracranial hemorrhage or infarct. A subsequent CT cerebral perfusion scan (Figure 1) was notable for areas of ischemia in the right cingulate gyrus as well as the medial frontal and parietal lobes. CT angiogram of the neck revealed bilateral atherosclerotic plaque in the carotid arteries; however, there was no evidence of any flow-limiting stenosis.

    The use of body simulators to control the quality of X-ray images is a practice that guarantees the control of essential parameters for diagnosis by the technique. The evolution of the equipment, between the analogue, digital computerized radiology (CR) and direct radiography (DR), requires evaluation of the equivalence in grayscale, of simulators, for an adjustment according to the specific technology of obtaining the image. In this sense, the present work presents the evaluation of a body simulator with regard to the representation of mean values of signal, noise and contrast obtained in chest radiographs and panoramic of the abdomen. For the thorax the cardiac region was considered as simulation target and for the abdomen simulation of the liver and small intestine. We used a retrospective study of images obtained with X-ray equipment - CR system, in which the images were studied using the ImageJ program, generating a data catalog. These were subsequently compared with those obtained experimentally using gel filled polymer body simulator. For the validation of the simulator, it was observed the gel equivalence of filling of the polymer box required to reach the image parameters of the cataloged radiographs. The results are discussed as to the physical principles of radiation interaction with biological and equivalent tissues

    Full Text Available Knowledge of variations of blood vessels of the abdomen is important during operative, diagnostic and endovascular pro- cedures. During routine dissection of the abdominal cavity, we came across multiple vascular anomalies involving renal, suprarenal and testicular arteries. The left kidney was supplied by two renal arteries originating together from the abdomi- nal aorta, and the right kidney was supplied by two accessory renal arteries, one of which was arising from the right renal artery and the other one from the aorta (about 2 inches below the origin of the renal artery. Accessory renal veins were present on both sides. The right testicular artery was arising from the lower accessory renal artery. The left testicular artery was looping around the inferior tributary of the left renal vein, whereby forming a sharp kink. The left middle suprarenal artery was diving into three small branches; the upper two branches were supplying the left suprarenal gland, whereas the lower branch was supplying the left kidney. Furthermore, detailed literature and the clinical and surgical importance of the case are discussed. [Arch Clin Exp Surg 2015; 4(3.000: 168-171

Método: Análisis retrospectivo de FI por abdomen hostil de 2000 a 2011 y su seguimiento a largo plazo. Comparamos el tiempo libre de oclusión quirúrgica antes y después de la FI. Resultados: Se incluyeron 20 FI en 19 pacientes. Predominaron las causas congénitas, la mediana de edad en la cirugía fue de 6 meses, todos tenían cirugías previas con mediana de tres, y dos de ellas fueron por oclusión intestinal previa. La férula se quitó a los 28 días (mediana). Con un seguimiento de 1-183 meses, hubo una recurrencia de oclusión quirúrgica. El tiempo libre de oclusión quirúrgica posferulización fue significativamente mayor que el preferulización mediante la prueba de Wilcoxon, con un valor Z = -3.594; p = el tiempo libre de oclusión quirúrgica.

    At present, there is a vivid debate on the role of the Helical CT (HCT) in the acute abdomen, principally on the usefulness of the non contrast HCT. We aim to present the most common semiological findings and the differential diagnoses, and to give a short description of the indications and protocols, according to the existing literature and to our experience with HCT during the last three years. We believe that the generalization of the use of HCT in emergencies avoid unnecessary surgery and shorten observation times on many occasions, with clear benefits in the clinical management of the patients.

    Full Text Available INTRODUCTION: The open abdomen is both a resource and a surgical sequela after damage-control surgery, that helps saving the live of critically ill patients. It can have significant complications, the most severe one is the entero-atmospheric fistula. CASE REPORT: We report the case of a patient from our hospital, treated with longstanding open abdomen because of a traumatic pancreatitis and development of an enteroatmospheric fistula, handled with a variation of the fistula ring technique: a "fireplace" design in a vacuum system. A review of the literature on the subject is made. RESULTS AND CONCLUSIONS: This strategy proved effective for the management of the fistula until the final repair of the bowel. The management of an enteroatmospheric fistula is a major technical challenge to prevent the leak of intestinal contents on the surrounding exposed bowel and granulation tissue. The "fireplace" design represents a good option for distal ileum fistulas, greatly simplifying the treatment of the patient by maintaining the open abdomen clean and the fistula effluent isolated until the transit repair, which is usually carried out along with the abdominal wall repair, few months later.

    Our purpose was to assess the performance of a new combination of neutral oral contrast for CT abdomen and CT Enterography in comparison with commercially available neutral oral contrast VoLumen. Seventy three consecutive patients were given sorbitol/CMC (Carboxy Methyl Cellulose) solution or VoLumen as oral contrast agent for abdominal computed tomography (CT) scan. 23 patients were male and 37 females. Age range was between 16 and 67 years. Since the use of CT scan for abdominal pathologies, there was need to separate bowel loops to localize the pathology. Three types of oral contrast can be used in CT-Scan abdomen; Positive, Neutral and negative. The above used contrasts are Neutral contrast these refers to agents that have an attenuation value similar to that of water (0-30 H).Our results show this new combination of Cc and Sorbitol to be equally good as VoLumen, for luminal distension and mural details, in duodenum and jejunum. While better than VoLumen for Ileal distension. (author)

    Full Text Available Acute abdomen with hemoperitoneum is a very rare entity in postmenopausal women due to gynecologic conditions. A 54-year-old, postmenopausal woman was brought to emergency department with severe abdominal pain. Physical examination revealed acute abdomen findings with 15 cm pelvic mass on the right adnexal region. Immediate exploratory laparotomy was performed. During laparotomy 1000 cc of bloodstained fluid, ruptured and actively bleeding large mass arising from right ovary was observed. Right salpingo-oopherectomy was performed in emergency conditions, and pathology report revealed an adult type of granulosa cell tumor. After this result, staging surgery was performed and patient was diagnosed as granulosa cell tumor stage 1 c. Cisplatin, etoposide, and bleomycin chemotherapy was given. Clinicians should be aware of granulosa cell tumors which may occur at any age and prone to rupture. Frozen section will be helpful in order to avoid incomplete surgeries especially in postmenopausal women presented with intra-abdominal bleeding.

    Full Text Available Introduction: This study aimed to investigate the effect of carpet weaving at a proposed workstation on Upper Trapezius (UTr fatigue during a task cycle. Fatigue in the shoulder is one of the most important precursors for upper limb musculoskeletal disorders. One of the most prevalent musculoskeletal disorders between carpet weavers is disorder of the shoulder region. Methods: This cross-sectional study, included eight females and three males. During an 80-minute cycle of carpet weaving, Electromyography (EMG signals of right and left UTr were recorded by the surface EMG, continuously. After raw signals were processed, MPF and RMS were considered as EMG amplitude and frequency parameters. Time series model and JASA methods were used to assess and classify the EMG parameter changes during the working time. Results: According to the JASA method, 58%, 16%, 8% and 8% of the participants experienced fatigue, force increase, force decrease and recovery, respectively in the right UTr. Also, 50%, 25%, 8% and 16% of the participants experienced fatigue, force increase, force decrease and recovery, respectively in the left UTr. Conclusions: For the major portion of the weavers, dominant status in Left and right UTr was fatigue, at the proposed workstation during a carpet weaving task cycle. The results of the study provide detailed information for optimal design of workstations. Further studies should focus on fatigue in various muscles and time periods for designing an appropriate and ergonomics carpet weaving workstation

    Non-compact left ventricle/hypertrabeculated left ventricle is a myocardiopatie produced by an arrest of the normal left ventricular compaction process during the early embryogenesis. It is associated to cardiac anomalies (congenital cardiopaties) as well as to extracardial conditions (neurological, facial, hematologic, cutaneous, skeletal and endocrinological anomalies). This entity is frequently unnoticed, being diagnosed only in centers with great experience in the diagnosis and treatment of myocardiopathies. Many cases of non-compact left ventricle have been initially misdiagnosed as hypertrophic myocardiopatie, endocardial fibroelastosis, dilated cardiomyopatie, restrictive cardiomyopathy and endocardial fibrosis. It is reported the case of a 74 years old man with a history of chronic arterial hypertension and diabetes mellitus, prechordial chest pain and mild dyspnoea. An echocardiogram showed signs of non-compact left ventricle with prominent trabeculations and deep inter-trabecular recesses involving left ventricular apical segment and extending to the lateral and inferior walls. Literature on this topic is reviewed

    Full Text Available A new species of Parotocinclus is described from the upper rio Piranhas-Açu basin, northeastern Brazil. The new species differs from all its congeners, except P. bidentatus, P. muriaensis (both from rio Paraíba do Sul basin, southeastern Brazil, and P. spilurus (rio Jaguaribe basin, northeastern Brazil by presenting the adipose fin rudimentary or absent. The new species differs from P. bidentatus, P. muriaensis, and P. spilurus mainly by presenting the abdomen region extensively naked, with few reduced rounded dermal platelets between the pectoral girdle and the anus. Parotocinclus seridoensis is probably an endemic species of the semi-arid Caatinga, region where the genus presents high species richness.

    Case presentation: The patient is a forty six years old man. He complained of frequent colic pain in left upper quadrant of abdomen for two months before admitting to the hospital. The pain resolved spontaneously after a few hours. This situation almost has been repeated every week. The patient had severe repeated melena and faint for two weeks. As soon as the patient was entered the Sina Hospital in 2012, supportive care was started. Then upper gastrointestinal endoscopy was performed for him and the bleeding point was detected. Also abdominal and pelvic computed tomography with oral and intravenous contrast was done. Finally the patient was operated on tumor diagnosis in duodenal area according to classic Whipple procedure. Conclusion: Gastrointestinal bleeding is the most common symptom of gastrointestinal stromal tumors. The bleeding is minimal and chronic. It will be progress to sudden and severe bleeding. Diagnosis is done by upper gastrointestinal endoscopy and biopsy. The large tumors with high mitotic

    PurposeOur experience with endovascular embolization (EVE) of the bronchial artery (BA) originating from the upper portion of the aortic arch (AA) in six patients is described.MethodsAltogether, 818 patients with hemoptysis underwent multidetector row computed tomography angiography (MDCTA) before EVE or AA angiography during EVE. Aberrant BAs originating from the upper portion of the AA were the source of massive hemoptysis in six patients (0.73 %). MDCT angiograms and/or Digital subtraction angiograms were retrospectively reviewed. Selective catheterization and embolization were performed.ResultsThe ostia of the BAs were located on the superior surface of the AA between the brachiocephalic trunk and left common carotid artery in three patients, the junction of the aorta and medial surface of the left subclavian artery in two, and the posterior wall of the upper portion of the AA in one. The six BAs comprised two common trunks, three single right sides, and one single left side. The targeted vessels were successfully catheterized and embolized by a coaxial microcatheter system using polyvinyl alcohol particles. Other pathologic BAs and nonbronchial systemic arteries also were embolized. Bleeding was immediately controlled in all patients with no recurrence of hemoptysis. No procedure-related complications occurred.ConclusionsApplication of EVE of anomalous origin of BAs in patients with hemoptysis is important, as demonstrated in the six reported patients. MDCTA before EVE or AA angiography during EVE is critical to avoid missing a rare aberrant BA originating from the upper portion of the AA

  1. Upper Limb Asymmetry in the Sense of Effort Is Dependent on Force Level

    Full Text Available Previous studies have shown that asymmetries in upper limb sensorimotor function are dependent on the source of sensory and motor information, hand preference and differences in hand strength. Further, the utilization of sensory and motor information and the mode of control of force may differ between the right hand/left hemisphere and left hand/right hemisphere systems. To more clearly understand the unique contribution of hand strength and intrinsic differences to the control of grasp force, we investigated hand/hemisphere differences when the source of force information was encoded at two different force levels corresponding to a 20 and 70% maximum voluntary contraction or the right and left hand of each participant. Eleven, adult males who demonstrated a stronger right than left maximum grasp force were requested to match a right or left hand 20 or 70% maximal voluntary contraction reference force with the opposite hand. During the matching task, visual feedback corresponding to the production of the reference force was available and then removed when the contralateral hand performed the match. The matching relative force error was significantly different between hands for the 70% MVC reference force but not for the 20% MVC reference force. Directional asymmetries, quantified as the matching force constant error, showed right hand overshoots and left undershoots were force dependent and primarily due to greater undershoots when matching with the left hand the right hand reference force. Findings further suggest that the interaction between internal sources of information, such as efferent copy and proprioception, as well as hand strength differences appear to be hand/hemisphere system dependent. Investigations of force matching tasks under conditions whereby force level is varied and visual feedback of the reference force is available provides critical baseline information for building effective interventions for asymmetric (stroke

    The precise radiotherapy has been widely used in the clinics. But there are many factors that affect the accuracy in the course of implementation. Finally the effect of radiotherapy is affected. These factors are reviewed. And the previous research data about the abdomen tumors is summed up. Also how the accuracy was affected by the respiratory movement, positioning, position fixed technology, weight, retraction and motion of the tumor and the situation of surrounding organs will be analyzed. At last, how to avoid these errors in clinics will be discussed. (authors)

    We utilized functional magnetic resonance imaging (fMRI) to evaluate the common brain region of motor imagery for the right and left upper and lower limbs. The subjects were instructed to repeatedly imagined extension and flexion of the right or left hands/ankles. Brain regions, which included the supplemental motor area (SMA), premotor cortex and parietal cortex, were activated during motor imagery. Conjunction analysis revealed that the left SMA and inferior frontal gyrus (IFG)/ventral premotor cortex (vPM) were commonly activated with motor imagery of the right hand, left hand, right foot, and left foot. This result suggests that these brain regions are activated during motor imagery in an effector independent manner. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2006-01-01

    Purpose: To report the tolerability and efficacy of twice-daily whole-abdomen irradiation (WAI) for non-Hodgkin's lymphoma (NHL). Methods and Materials: Of 123 patients treated for NHL with WAI, 37% received previous chemotherapy, 28% received WAI as part of comprehensive lymphatic irradiation (CLI), and 32% received WAI for palliation. The median dose to the whole abdomen was 25.0 Gy, followed by a median tumor boost of 9.8 Gy in 58 patients. Fractionation was 1.0 Gy once daily (54%) or 0.8 Gy twice daily (46%). Blood counts were measured weekly. Results: At a median follow-up of 4.3 years, local control was 72% and overall survival was 55% at 5 years. Median time of WAI was 42 days for once-daily treatment and 32 days for twice-daily treatment. Patients receiving twice-daily WAI did not have a significantly higher rate of acute side effects (e.g., nausea, diarrhea, platelet or red blood cell toxicity). Overall, acute thrombocytopenia was the most frequent side effect of treatment; 24 of 96 patients (25%) with available hematologic data had Grade 3+ toxicity. There was no acute Grade 3 gastrointestinal toxicity and no late small bowel obstruction. Multiple regression indicated that patients with four or less involved sites and disease size ≤6 cm had improved local control and overall survival. Conclusions: Twice-daily WAI using 0.8 Gy/fraction does not appear to have any greater toxicity compared with once-daily treatment using 1 Gy/fraction. Small doses per fraction (0.8-1 Gy/fx) are effective, tolerated well in the acute setting, and associated with a low rate of late toxicity

    Full Text Available Background: Mechanical neck pain is the most common type of neck pain and commonly to accompany with radiculopathy. Patients of neck pain exhibit greater activation of accessory muscles, (sternocleidomastoid, anterior scalene, and upper trapezius muscles and may also show changed patterns of motor control of other postural muscles as pelvic muscles for reducing activation of painful muscles of neck. Aim of the study: To determine if there is an association between gluteus maximus inhibition and overactivity of upper fibres of trapezius in patients with chronic mechanical neck pain with radiculopathy. Materials and Methods: Forty female patients participated in this study diagnosed as chronic mechanical neck pain with radiculopathy. Amplitude and onset of muscle activation were assessed by using the surface electromyography (EMG during prone hip extension test. Results: The results of this study demonstrated that there is no correlation between the amplitude of EMG activity of right and left gluteus maximus and the amplitude of EMG activity of right and left upper trapezius (P<0.05. Conclusion: It can be concluded that the overactivity of the upper trapezius muscle in patients with chronic mechanical neck pain with radiculopathy is not related to the inhibition of the gluteus maximus muscle during prone hip extension test.

    Radiotherapy induced diarrhea and convulsive pain are severe side-effects of irradiation of the pelvis and the abdomen leading often to an interruption of the treatment. Up to now these side-effects were only treated symptomatically, prophylactic therapies are not known. During the years 1992 and 1993 174 patients who obtained radiotherapy in the pelvis or the abdomen because of different malignancies were observed referring to the diarrhea-prophylactic effect of Smectite (=Skilpin R ). 80 patients received Smectite at the beginning of radiotherapy, 94 patients of the controlgroup were treated with motility modifying drugs when diarrhea appeared. The following parameters were compared: Frequency, consistence and incontinence of stool, tenesmus and the onset of diarrhea. 67,0% (n=63) of the patients in the controlgroup developed diarrhea, whereas in the pretreated Smectite-group only 37,5% of the cases (n=30) developed diarrhea. The first appearance of diarrhea was at day 17 in the pretreated group and averagely at day 11 in the controlgroup. 44% of the patients in the controlgroup suffered from tenesmus versus 25% in the Smectite-group. In comparison to the symptomatic treatment of radiation enteritis the prophylactic application of Smectite is able to reduce the diarrhea from the beginning of raditherapy or at least to reduce the pathological frequency of stool and therefore to increase the quality of life.

    In a review of 1708 consecutive CT examinations of the abdomen the position of the ascending and descending colon in relation to the posterial and lateral edge of the kidney was studied. It was found that part of the colon was positioned posterior or posterolateral to the kidney's edge in percentages that varied between 14.2% and 0.9% in the different sex groups at the levels of upper, mid- and lower poles of the right and left kidney. It is concluded that this anatomical variation should be known if colon perforation is to be avoided during percutaneous nephrostomy of biopsy. (author). 15 refs.; 4 figs.; 2 tabs

    Full Text Available History of present illness: A 54-year old female presented to the emergency department with complaints of fevers, dysuria, urinary frequency, and diffuse abdominal pain. Her temperature was 103°F, but the remainder of her vital signs were normal. Upon physical examination, the patient had tenderness to palpation in the left upper and left lower abdomen and left costovertebral angle tenderness. Due to the location of pain (diverticulitis is in the differential for left-sided abdominal pain in this age group and patient’s reported history of nephrolithiasis, a computed tomography (CT scan of the abdomen and pelvis with intravenous (IV contrast was ordered because the physician felt this could best work up both of these possible conditions. Significant findings: A CT abdomen and pelvis with IV contrast showed neither nephrolithiasis nor diverticulitis, and instead showed heterogeneous enhancement of the left kidney with mild edematous enlargement and striated left nephrogram. Significant perinephric stranding (red arrows was also noted and was consistent with severe acute pyelonephritis. Discussion: Acute pyelonephritis (APN is a bacterial infection of the renal parenchyma which can present with a spectrum of symptoms including flank pain, high-grade fever, vomiting, and urinary tract symptoms.1,2 The diagnosis of APN can be made based on these clinical features with associated laboratory findings of bacteriuria, pyuria, positive urine cultures, and leukocytosis.1,2,7 Early diagnosis and treatment of APN is essential to prevent complications such as renal abscess or infarct, which could lead to renal failure, sepsis, and shock.3 CT has a sensitivity and specificity of 86.8% and 87.5%, respectively, for diagnosing APN. Common findings include striated nephrograms or perinephric fat stranding.2 However, imaging is not required for diagnosis and is typically reserved for patients who are immunocompromised, have severe symptoms, or show no clinical

    The objective of this study is comparing colon diversion versus primary repair in penetrating colon gunshot injuries. A retrospective study of 63 cases of gunshot abdomen with penetrating colon injury were admitted to Al-jalla Hospital in 2011 in Benghazi, Libya. After surgical intervention, these patients were observed for any postoperative complications. During the study period, 63 eligible patients included, 62 (98.4%) were males and 1 (1.6%) was female. And the mean age was 29.24 years. Eighteen patients had an injury on the right side of the colon, while 16, 6, 11, 6, 2, 3, and 1 patients had an injury on the transverse, left, sigmoid, rectum, right transverse, left transverse, and total colonic injury, respectively. In the first group, 23 patients (36.5%) was treated with colon diversion, (2 with Hartmann's operation, 21 with loop colostomy). In the second group, 40 patients (63.4 %) was treated with primary repair. Eighteen (28.5%) with right hemicolectomy, 5 (7.9%) with transverse colon resection and anastomosis, and 17 (26.9%) with simple repair. We evaluate the rate of postoperative complication and compare the postoperative morbidity between both groups. In our study, there was no significant statistical difference between types of operations and rate of complications (P = 0.18). We could not see any advantage of the diversion over the primary repair. To reduce risk of the psychological trauma, complications of colostomy, unnecessary repeated hospitalization, decrease of economic cost, and complications of stoma revision operation, we should consider that the primary repair of penetrating colon injuries is an acceptable alternative method of treatment over the colostomy.

  14. Abdomen disease diagnosis in CT images using flexiscale curvelet transform and improved genetic algorithm.

    2015-12-01

    This paper presents an abdomen disease diagnostic system based on the flexi-scale curvelet transform, which uses different optimal scales for extracting features from computed tomography (CT) images. To optimize the scale of the flexi-scale curvelet transform, we propose an improved genetic algorithm. The conventional genetic algorithm assumes that fit parents will likely produce the healthiest offspring that leads to the least fit parents accumulating at the bottom of the population, reducing the fitness of subsequent populations and delaying the optimal solution search. In our improved genetic algorithm, combining the chromosomes of a low-fitness and a high-fitness individual increases the probability of producing high-fitness offspring. Thereby, all of the least fit parent chromosomes are combined with high fit parent to produce offspring for the next population. In this way, the leftover weak chromosomes cannot damage the fitness of subsequent populations. To further facilitate the search for the optimal solution, our improved genetic algorithm adopts modified elitism. The proposed method was applied to 120 CT abdominal images; 30 images each of normal subjects, cysts, tumors and stones. The features extracted by the flexi-scale curvelet transform were more discriminative than conventional methods, demonstrating the potential of our method as a diagnostic tool for abdomen diseases.

    The present study explored the relationship between the regional Cold-Heat sensation, the key indicator of the Cold-Heat patterns in traditional East Asian medicine (TEAM), and various biomarkers in Korean population. 734 apparently healthy volunteers aged 20 years and older were enrolled. Three scale self-report questions on the general thermal feel in hands, legs, and abdomen were examined. We found that 65% of women tended to perceive their body, particularly their hands and legs, to be cold, versus 25% of men. Energy expenditure and temperature load at resting state were lower in women, independently of body mass index (BMI). Those with warm hands and warm legs had a 0.74 and 0.52 kg/m 2 higher BMI than those with cold hands and cold legs, respectively, regardless of age, gender, and body weight. Norepinephrine was higher, whereas the dynamic changes in glucose and insulin during an oral glucose tolerance test were lower in those with cold extremities, particularly hands. No consistent differences in biomarkers were found for the abdominal dimension. These results suggest that gender, BMI, the sympathetic nervous system, and glucose metabolism are potential determinants of the Cold-Heat sensation in the hands and legs, but not the abdomen.

Those with warm hands and warm legs had a 0.74 and 0.52 kg/m2 higher BMI than those with cold hands and cold legs, respectively, regardless of age, gender, and body weight. Norepinephrine was higher, whereas the dynamic changes in glucose and insulin during an oral glucose tolerance test were lower in those with cold extremities, particularly hands. No consistent differences in biomarkers were found for the abdominal dimension. These results suggest that gender, BMI, the sympathetic nervous system, and glucose metabolism are potential determinants of the Cold-Heat sensation in the hands and legs, but not the abdomen.

    Catamenial pneumothorax (CP) is generally caused by intraperitoneal air leaking from the uterus into the thoracic cavity via a defect in the endometrial tissue of the diaphragm and is usually detected in the right thorax. We report a case of left-sided CP caused by endometriosis in the visceral pleura and with no abnormal findings in the diaphragm. A 33-year-old female patient presented at the end of a course of low-dose contraceptive pills for pelvic endometriosis, with spontaneous pneumothorax in the left chest. Chest CT revealed a bulla in the left upper lung lobe. The patient underwent partial resection of the lung. Immunohistochemistry confirmed the presence of endometrial stromal tissue in the visceral pleura and confirmed this as the cause of pneumothorax since there were no observable abnormalities in the diaphragm. This case suggests that immunohistochemical examination of patients with spontaneous pneumothorax can detect alternative endometrial lesions.

    There are studies to prove the role of amylase and lipase estimation as a screening diagnostic tool to detect diseases apart from acute pancreatitis. However, there is sparse literature on the role of serum and urine amylase, lipase levels, etc to help predict the specific intra-abdominal injury after blunt trauma abdomen (BTA). To elucidate the significance of elevation in the levels of amylase and lipase in serum and urine samples as reliable parameters for accurate diagnosis and management of blunt trauma to the abdomen. A prospective analysis was done on the trauma patients admitted in Jai Prakash Narayan Apex Trauma Center, AIIMS, with blunt abdomen trauma injuries over a period of six months. Blood and urine samples were collected on days 1, 3, and 5 of admission for the estimation of amylase and lipase, liver function tests, serum bicarbonates, urine routine microscopy for red blood cells, and complete hemogram. Clinical details such as time elapsed from injury to admission, type of injury, trauma score, and hypotension were noted. Patients were divided into groups according to the single or multiple organs injured and according to their hospital outcome (dead/discharged). Wilcoxon's Rank sum or Kruskal-Wallis tests were used to compare median values in two/three groups. Data analysis was performed using STATA 11.0 statistical software. A total of 55 patients with median age 26 (range, 6-80) years, were enrolled in the study. Of these, 80% were males. Surgery was required for 20% of the patients. Out of 55 patients, 42 had isolated single organ injury [liver or spleen or gastrointestinal tract (GIT) or kidney]. Patients with pancreatic injury were excluded. In patients who suffered liver injuries, urine lipase levels on day 1, urine lipase/amylase ratio along with aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) on days 1, 3, and 5, were found to be significant. Day 1 serum amylase, AST, ALT, hemoglobin, and

    Patient: Female, 91 Final Diagnosis: Nutcracker syndrome • celiacomesenteric trunk Symptoms: Dyspepsia • dysphagia Medication: — Clinical Procedure: — Specialty: Surgery Objective: Congenital defects/diseases Background: Celiacomesenteric trunk (CMT) is a very rare anatomic finding in which the celiac artery and the superior mesenteric artery (SMA) originate from the abdominal aorta through a common trunk. Clinical associations with CMT include arterial aneurysm, thrombosis, and celiac artery compression. However, an association between CMT and abdominal venous congestion caused by left renal vein compression, or ‘nutcracker phenomenon,’ has not been previously reported. Case Report: A 91-year-old woman, who died from a cerebrovascular accident (CVA), underwent a cadaveric examination at our medical school. On examination of the abdomen, there was an incidental finding of CMT. The arterial and venous diameters were measured, and vascular histopathology was undertaken. The vascular anatomy was consistent with CMT type 1-b. Nutcracker phenomenon (NCP) (left renal vein compression) was seen anatomically as dilatation and engorgement of the left renal vein, relative to the right renal vein (10.77±0.13 mm vs. 4.49±0.56 mm, respectively), and dilatation and engorgement of the left ovarian vein, relative to the right ovarian vein (4.37±0.15 mm vs. 1.06±0.09 mm, respectively) with left ovarian varicocele. The aortoceliac angle (ACA) and the aortomesenteric angle (AMA) approached zero degrees. Conclusions: We have described a rare anatomic finding of CMT that created an acute AMA and NCP. Awareness of this rare association between CMT and NCP by clinicians, vascular surgeons, and radiologists may be of value in the future evaluation and surgical management of patients who present clinically with ‘nutcracker syndrome.’ PMID:29242494

    Full Text Available History of present illness: A 58-year-old female with history of thrombotic disorder presented to emergency department (ED with constant, sharp pain in her lower abdomen radiating to her back for the past day. She denied nausea, vomiting, changes in bowel habits, or recent abdominal trauma. The patient had been recently transitioned from warfarin to enoxaparin after having a shoulder surgery one week prior to her presentation. On exam, the patient was tachycardic, hypotensive, and pale. She had significant abdominal tenderness to the left upper and lower quadrants, and left flank. Her initial hemoglobin (Hbg was 8.9 g/dL, but dropped to 6.1 g/dL during her ED course, requiring emergent blood transfusion. Significant findings: Bedside ultrasound was performed and demonstrated a hypoechoic area within the left kidney (images not shown. The non-contrast computed tomography (CT of the abdomen and pelvis shows a significantly enlarged left kidney and a region of high-attenuation encapsulating the left kidney, concerning for acute hemorrhage. Discussion: The cause for spontaneous subcapsular renal hematoma (SPH is not entirely clear.1 It may mimic acute appendicitis or a dissecting aneurysm.2 The use of ultrasound in the emergency setting can detect SPH; however, CT is preferred because it can distinguish between a renal mass, abscess, or collection of blood.3 Most SPH cases are associated with renal tumors, and radical nephrectomy is recommended.4 When the etiology cannot be determined, conservative management may be appropriate.5 The use of anticoagulant and antiplatelet medications may be a predisposing factor, since their usage has been implicated in cases of SPH in the past.4,6 This patient was evaluated by interventional radiology, but she was not a candidate for embolization due to a significant contrast allergy. She was therefore admitted to general surgery and underwent exploratory laparotomy. A left-sided adrenal mass was discovered with

    Forearm blood pressures have been suggested as an alternative site to measure blood pressures when the upper arm is unavailable. However there is little evidence utilising clinical populations to support this substitution. To determine agreement between blood pressures measured in the left upper arm and forearm using a singular oscillometric non-invasive device in adult Emergency Department patients. The secondary objective was to explore the relationship of blood pressure differences with age, sex, ethnicity, smoking history and obesity. Single centre comparison study. Adult Emergency Department, Tertiary Trauma Centre. Forty-four participants who met inclusion/exclusion criteria selected sequentially from the Emergency Department arrival board. A random assignment of order of measurement for left upper arm and forearm blood pressures was utilised. Participants were eligible if they were aged 18 years or older, had been assigned an Australasian Triage Scale code of 2, 3, 4, or 5, were able to consent, and able to have blood pressures measured on their left arm whilst lying at a 45° angle. The Bland-Altman method of statistical analysis was used, with the level of agreement for clinical acceptability for the systolic, diastolic and mean arterial pressure defined as ±10 mmHg. The forearm measure overestimated systolic (mean difference 2.2 mmHg, 95% limits of agreement ±19 mmHg), diastolic (mean difference 3.4 mmHg, 95% limits of agreement ±14.4 mmHg), and mean arterial pressures (mean difference 4.1 mmHg, 95% limits of agreement ±13.7 mmHg). The systolic measure was not significantly different from zero. Evidence of better agreement was found with upper arm/forearm systolic measures below 140 mmHg compared to systolic measures above 140 mmHg using the Levene's test (p=0.002, F-statistic=11.09). Blood pressure disparity was not associated with participant characteristics. Forearm measures cannot routinely replace upper arm measures for blood pressure measurement

    Upper limb apraxia, a disorder of higher motor cognition, is a common consequence of left-hemispheric stroke. Contrary to common assumption, apraxic deficits not only manifest themselves during clinical testing but also have delirious effects on the patients' everyday life and rehabilitation. Thus, a reliable diagnosis and efficient treatment of upper limb apraxia is important to improve the patients' prognosis after stroke. Nevertheless, to date, upper limb apraxia is still an underdiagnosed and ill-treated entity. Based on a systematic literature search, this review summarizes the current tools of diagnosis and treatment strategies for upper limb apraxia. It furthermore provides clinicians with graded recommendations. In particular, a short screening test for apraxia, and a more comprehensive diagnostic apraxia test for clinical use are recommended. Although currently only a few randomized controlled studies investigate the efficacy of different apraxia treatments, the gesture training suggested by Smania and colleagues can be recommended for the therapy of apraxia, the effects of which were shown to extend to activities of daily living and to persist for at least 2 months after completion of the training. This review aims at directing the reader's attention to the ecological relevance of apraxia. Moreover, it provides clinicians with appropriate tools for the reliable diagnosis and effective treatment of apraxia. Nevertheless, this review also highlights the need for further research into how to improve diagnosis of apraxia based on neuropsychological models and to develop new therapeutic strategies.

    Pain originating from the organs of the upper abdomen, especially in patients suffering from inoperable carcinoma of the pancreas or advanced inflammatory conditions, is difficult to treat in a significant number of patients. Computed tomography (CT) guided neurolysis is the most commonly used technique for neurolysis of the celiac plexus. Ethanol is used to destroy the nociceptive fibers passing through the plexus and provides an effective means of diminishing pain arising from the upper abdomen. Using either an anterior or posterior approach, a 22 G Chiba needle is advanced to the antecrural space and neurolysis is achieved by injecting a volume of 20-50 ml of ethanol together with a local anesthetic and contrast medium. In up to 80 % of patients suffering from tumors of the upper abdomen, CT-guided celiac plexus neurolysis diminishes pain or allows a reduction of analgesic medication; however, in some patients the effect may only be temporary necessitating a second intervention. In inflammatory conditions, celiac neurolysis is often less effective in reducing abdominal pain. The CT-guided procedure for neurolysis of the celiac plexus is safe and effective in diminishing pain especially in patients suffering from tumors of the upper abdomen. The procedure can be repeated if the effect is only temporary. (orig.) [de

    To recognize the user's motion intention, brain-machine interfaces (BMI) usually decode movements from cortical activity to control exoskeletons and neuroprostheses for daily activities. The aim of this paper is to investigate whether self-induced variations of the electroencephalogram (EEG) can be useful as control signals for an upper-limb exoskeleton developed by us. A BMI based on event-related desynchronization/synchronization (ERD/ERS) is proposed. In the decoder-training phase, we investigate the offline classification performance of left versus right hand and left hand versus both feet by using motor execution (ME) or motor imagery (MI). The results indicate that the accuracies of ME sessions are higher than those of MI sessions, and left hand versus both feet paradigm achieves a better classification performance, which would be used in the online-control phase. In the online-control phase, the trained decoder is tested in two scenarios (wearing or without wearing the exoskeleton). The MI and ME sessions wearing the exoskeleton achieve mean classification accuracy of 84.29% ± 2.11% and 87.37% ± 3.06%, respectively. The present study demonstrates that the proposed BMI is effective to control the upper-limb exoskeleton, and provides a practical method by non-invasive EEG signal associated with human natural behavior for clinical applications.

    In solid organ transplantation, the disparity between donor supply and patients awaiting transplant continues to increase. The organ shortage has led to relaxation of historic contraindications to organ donation. A large percentage of deceased organ donors have been subjected to traumatic injuries, which can often result in intervention that leads to abdominal packing and intensive care unit resuscitation. The donor with this "open abdomen" (OA) presents a situation in which the risk of organ utilization is difficult to quantify. There exists a concern for the potential of a higher risk for both bacterial and fungal infections, including multidrug-resistant (MDR) pathogens because of the prevalence of antibiotic use and critical illness in this population. No recommendations have been established for utilization of organs from these OA donors, because data are limited. Herein, we report a case of a 21-year-old donor who had sustained a gunshot wound to his abdomen, resulting in a damage-control laparotomy and abdominal packing. The donor subsequently suffered brain death, and the family consented to organ donation. A multiorgan procurement was performed with respective transplantation of the procured organs (heart, liver, and both kidneys) into 4 separate recipients. Peritoneal swab cultures performed at the time of organ recovery grew out MDR Pseudomonas aeruginosa on the day after procurement, subsequently followed by positive blood and sputum cultures as well. All 4 transplant recipients subsequently developed infections with MDR P. aeruginosa, which appeared to be donor-derived with similar resistance patterns. Appropriate antibiotic coverage was initiated in all of the patients. Although 2 of the recipients died, mortality did not appear to be clearly associated with the donor-derived infections. This case illustrates the potential infectious risk associated with organs from donors with an OA, and suggests that aggressive surveillance for occult infections

    Aim: To evaluate the diagnostic performance of magnetic resonance urography (MRU) versus retrograde pyelography and/or ureteroscopy (RPU) in the detection of upper urinary tract neoplasms. Materials and methods: This retrospective study included 35 patients with suspected upper urinary tract malignancy who underwent MRU and RPU within 6-months in our institution during the study period (February 2002 to January 2007). MRU and RPU reports were reviewed and results recorded. For each patient, the urinary tract was sub-divided into four regions for analysis: left kidney/renal pelvis, left ureter, right kidney/renal pelvis, and right ureter. MRU and RPU results for each patient were compared to a reference standard and the diagnostic performance of both techniques was compared. Results: A total of 113 regions were analysed on MRU and 90 regions on RPU. Nineteen neoplasms were identified. Sensitivity, specificity, positive predictive value, and negative predictive value for the detection of urinary tract neoplasms were 63, 91, 60, and 92% for MRU, respectively, and 53, 97, 83, and 88% for RPU, respectively. These differences were not statistically significant (p > 0.05). Conclusion: The high negative predictive value of MRU in the present series supports its use as a non-invasive screening examination for excluding the presence of upper urinary tract malignancy.

    The widespread use of computed tomography (CT) has increased the medical radiation exposure and cancer risk. We aimed to evaluate the impact of AIDR 3D in CT abdomen-pelvic examinations based on image quality and radiation dose in low dose (LD) setting compared to standard dose (STD) with filtered back projection (FBP) reconstruction. We retrospectively reviewed the images of 40 patients who underwent CT abdomen-pelvic using a 80 slice CT scanner. Group 1 patients ( n =20, mean age 41 ± 17 years) were performed at LD with AIDR 3D reconstruction and Group 2 patients ( n =20, mean age 52 ± 21 years) were scanned with STD using FBP reconstruction. Objective image noise was assessed by region of interest (ROI) measurements in the liver and aorta as standard deviation (SD) of the attenuation value (Hounsfield Unit, HU) while subjective image quality was evaluated by two radiologists. Statistical analysis was used to compare the scan length, CT dose index volume (CTDI vol ) and image quality of both patient groups. Although both groups have similar mean scan length, the CTDI vol significantly decreased by 38% in LD CT compared to STD CT ( p <0.05). Objective and subjective image quality were statistically improved with AIDR 3D ( p <0.05). In conclusion, AIDR 3D enables significant dose reduction of 38% with superior image quality in LD CT abdomen-pelvis. (paper)

    Full Text Available Background and Objectives: Before the advent of endoscopy direct access to the lesion for the confirmation of the diagnosis was difficult, this posed difficulty in contemplating adequate and appropriate surgery. Endoscopy as a diagnostic and therapeutic tool has grown in recent years. Upper gastrointestinal (GI endoscopy is one of the most fascinating branch which serves not only as a means of resolving or amplifying the diagnosis made clinically or by X-ray, but also a primary diagnostic procedure for conditions not otherwise diagnosable on unoperated case. Fiber optic upper GI endoscopy has already become firmly established as a reliable, quick and inexpensive tool. This study was done to detect the upper gastrointestinal lesions in rural population of Kolar District, the distribution pattern of various upper GI lesions in patients presenting with upper GI symptoms and to follow the endoscopic diagnosis for medical and surgical management. Materials and Methods: The study group includes patients reporting to outpatient department and also the inpatients in wards of General Surgery and other departments, who have upper GI symptoms, were advised endoscopy at R. L. JALAPPA Hospital and Research Centre, Kolar, from a period of December 2011 to August 2013. Results: Of the 600 cases, 370 were males, and 230 were females. Disease incidence was highest in 51-70 years age group, that is, 21.6%. Pain abdomen was the most common symptom. Epigastric tenderness was the most common sign among the patients clinically. Reflux esophagitis and diffuse gastritis formed most common cases (307 cases. The incidence of duodenitis - 7.83%, peptic ulcer -3.3%, esophageal varices - 1.5%, the incidence of carcinoma esophagus and carcinoma stomach was approximately same that is, 4.5% and 4.6% respectively. The incidence of esophageal candidiasis was 4.16%. The majority of the patients had a normal study that is, 14.5%. Conclusion: Upper GI lesions were more common in

    Radiological measurements are one of the key variables in widely adopted guidelines (WHO, RECIST) that standardize and objectivize response assessment in oncology care. Measurements are typically described in free-text, narrative radiology reports. We present a natural language processing pipeline that extracts measurements from radiology reports and pairs them with extracted measurements from prior reports of the same clinical finding, e.g., lymph node or mass. A ground truth was created by manually pairing measurements in the abdomen CT reports of 50 patients. A Random Forest classifier trained on 15 features achieved superior results in an end-to-end evaluation of the pipeline on the extraction and pairing task: precision 0.910, recall 0.878, F-measure 0.894, AUC 0.988. Representing the narrative content in terms of UMLS concepts did not improve results. Applications of the proposed technology include data mining, advanced search and workflow support for healthcare professionals managing radiological measurements.

However, there is sparse literature on the role of serum and urine amylase, lipase levels, etc to help predict the specific intra-abdominal injury after blunt trauma abdomen (BTA. Aim: To elucidate the significance of elevation in the levels of amylase and lipase in serum and urine samples as reliable parameters for accurate diagnosis and management of blunt trauma to the abdomen. Materials and Methods: A prospective analysis was done on the trauma patients admitted in Jai Prakash Narayan Apex Trauma Center, AIIMS, with blunt abdomen trauma injuries over a period of six months. Blood and urine samples were collected on days 1, 3, and 5 of admission for the estimation of amylase and lipase, liver function tests, serum bicarbonates, urine routine microscopy for red blood cells, and complete hemogram. Clinical details such as time elapsed from injury to admission, type of injury, trauma score, and hypotension were noted. Patients were divided into groups according to the single or multiple organs injured and according to their hospital outcome (dead/discharged. Wilcoxon′s Rank sum or Kruskal-Wallis tests were used to compare median values in two/three groups. Data analysis was performed using STATA 11.0 statistical software. Results: A total of 55 patients with median age 26 (range, 6-80 years, were enrolled in the study. Of these, 80% were males. Surgery was required for 20% of the patients. Out of 55 patients, 42 had isolated single organ injury [liver or spleen or gastrointestinal tract (GIT or kidney]. Patients with pancreatic injury were excluded. In patients who suffered liver injuries, urine lipase levels on day 1, urine lipase/amylase ratio along with aspartate aminotransferase (AST, alanine aminotransferase (ALT, and alkaline phosphatase (ALP on days 1, 3, and 5, were found to

    Musculoskeletal disorders associated with computer use span the joints of the upper extremity. Computing typically involves tapping in multiple directions. Thus, we sought to describe the loading on the finger, wrist, elbow and shoulder joints in terms of kinematic and kinetic difference across single key switch tapping to directional tapping on multiple keys. An experiment with repeated measures design was conducted. Six subjects tapped with their right index finger on a stand-alone number keypad placed horizontally in three conditions: (1) on single key switch (the number key 5); (2) left and right on number key 4 and 6; (3) top and bottom on number key 8 and 2. A force-torque transducer underneath the keypad measured the fingertip force. An active-marker infrared motion analysis system measured the kinematics of the fingertip, hand, forearm, upper arm and torso. Joint moments for the metacarpophalangeal, wrist, elbow, and shoulder joints were estimated using inverse dynamics. Tapping in the top-bottom orientation introduced the largest biomechanical loading on the upper extremity especially for the proximal joint, followed by tapping in the left-right orientation, and the lowest loading was observed during single key switch tapping. Directional tapping on average increased the fingertip force, joint excursion, and peak-to-peak joint torque by 45%, 190% and 55%, respectively. Identifying the biomechanical loading patterns associated with these fundamental movements of keying improves the understanding of the risks of upper extremity musculoskeletal disorders for computer keyboard users.

    Anatomical imaging findings indicating normal bowel rotation can be identified on cross-sectional imaging, including magnetic resonance imaging (MRI) performed for non-related indications. The goal of our study was to assess whether non-targeted MRI can accurately assess intestinal malrotation. Four anatomical landmarks were assessed on MRIs of the chest, spine or abdomen performed from January 2006 to June 2014, on patients who also had upper gastrointestinal series (UGI) performed within 10 years of the MRI date: 1) retroperitoneal duodenum, 2) left upper quadrant duodenojejunal junction, 3) superior mesenteric artery to the left of the superior mesenteric vein, and 4) right lower quadrant cecum. Two attending radiologists, one pediatric and one abdominal radiologist, independently reviewed the MR images. The pediatric radiologist reviewed images from UGI (considered the gold standard) to determine the intestinal rotation for each case. Validation of the criteria was performed on new patients imaged through January 2016. The original cohort included 109 MRIs (15 chest, 41 spine and 53 abdomen) done on 109 patients (42% males, mean age: 10.2 years). If each of the 4 anatomical questions were answered ''yes'' (4-YES), specificity was 100% for each radiologist and malrotation was appropriately excluded. Using the 4-YES criteria, the pediatric radiologist excluded malrotation in 71 patients (65%) and the abdominal radiologist excluded it in 65 (60%), with concurrence for 57 patients. Validation of the 4-YES criteria in 23 new patients appropriately proved the 4-YES rule, with neither labeling the one new malrotation case 4-YES. If a radiologist can confidently answer ''yes'' to the four questions evaluated in this study, then intestinal rotation can be safely considered normal. Normal bowel rotation should be commented upon in MRI reports when these four anatomical locations are imaged, thus helping patients avoid unnecessary

    Full Text Available Background/Objectives. Embolization of the left gastric artery (LGA, which preferentially supplies the gastric fundus, has been shown to produce weight loss in animal models. However, weight loss after LGA embolization in humans has not been previously established. The aim of this study was to evaluate postprocedural weight loss in patients following LGA embolization. Subjects/Methods. A retrospective analysis of the medical records of patients who underwent LGA embolization for upper gastrointestinal (GI bleeding was performed. Postprocedural weight loss in this group was compared to a control group of patients who had undergone embolization of other arteries for upper GI bleeding. Results. The experimental group (N=19 lost an average of 7.3% of their initial body weight within three months of LGA embolization, which was significantly greater than the 2% weight loss observed in the control group (N=28 (P=0.006. No significant differences were seen between the groups in preprocedural body mass index (BMI, age, postprocedural care in the intensive care unit, history of malignancy, serum creatinine, or left ventricular ejection fraction. Conclusions. The current data suggest that body weight in humans may be modulated via LGA embolization. Continued research is warranted with prospective studies to further investigate this phenomenon.

    Multiple mosquito-borne parasites cocirculate in nature and potentially interact. To understand the community of parasites cocirculating with West Nile virus (WNV), we screened the bloodmeal content of Culex pipiens L. mosquitoes for three common types of hemoparasites. Blood-fed Cx. pipiens were collected from a WNV-epidemic area in suburban Chicago, IL, from May to September 2005 through 2010. DNA was extracted from dissected abdomens and subject to PCR and direct sequencing to identify the vertebrate host. RNA was extracted from the head or thorax and screened for WNV using quantitative reverse transcriptase PCR. Seventy-nine engorged females with avian host origin were screened using PCR and amplicon sequencing for filarioid nematodes, Haemosporida, and trypanosomatids. Filarioid nematodes were identified in 3.8% of the blooded abdomens, Plasmodium sp. in 8.9%, Haemoproteus in 31.6%, and Trypanosoma sp. in 6.3%. The sequences from these hemoparasite lineages were highly similar to sequences from birds in prior studies in suburban Chicago. Overall, 50.6% of blood-fed Culex pipiens contained hemoparasite DNA in their abdomen, presumably from current or prior bloodmeals. Additionally, we detected hemoparasite DNA in the blooded abdomen of three of 10 Cx. pipiens infected with WNV. © The Authors 2015.

    To give an overview of the literature on left-sided acute appendicitis (LSAA) associated with situs inversus totalis (SIT) and midgut malrotation (MM). We present a new case of LSAA with SIT and a literature review of studies published in the English language on LSAA, accessed via PubMed and Google Scholar databases. Ninety-five published cases of LSAA were evaluated and a 25-year-old female, who presented to our clinic with left lower abdominal pain caused by LSAA, is reported. In the reviewed literature, fifty-seven patients were male and 38 were female with an age range of 8 to 82 years and a median age of 29.1 ± 15.9 years. Sixty-six patients had SIT, 23 had MM, three had cecal malrotation, and two had a previously unnoted congenital abnormality. Fifty-nine patients had presented to the hospital with left lower, 14 with right lower and seven with bilateral lower quadrant pain, and seven subjects complained of left upper quadrant pain. The diagnosis was established preoperatively in 49 patients, intraoperatively in 19, and during the postoperative period in five; 14 patients were aware of having this anomaly. The data of eight patients were not unavailable. Eleven patients underwent laparoscopic appendectomy, which was combined with cholecystectomy in two cases. Histopathological examination of the appendix specimens revealed adenocarcinoma in only two of 95 patients. The diagnosis of left lower quadrant pain is based on well-established clinical symptoms, physical examination and physician's experience.

    Full Text Available To recognize the user’s motion intention, brain-machine interfaces (BMI usually decode movements from cortical activity to control exoskeletons and neuroprostheses for daily activities. The aim of this paper is to investigate whether self-induced variations of the electroencephalogram (EEG can be useful as control signals for an upper-limb exoskeleton developed by us. A BMI based on event-related desynchronization/synchronization (ERD/ERS is proposed. In the decoder-training phase, we investigate the offline classification performance of left versus right hand and left hand versus both feet by using motor execution (ME or motor imagery (MI. The results indicate that the accuracies of ME sessions are higher than those of MI sessions, and left hand versus both feet paradigm achieves a better classification performance, which would be used in the online-control phase. In the online-control phase, the trained decoder is tested in two scenarios (wearing or without wearing the exoskeleton. The MI and ME sessions wearing the exoskeleton achieve mean classification accuracy of 84.29% ± 2.11% and 87.37% ± 3.06%, respectively. The present study demonstrates that the proposed BMI is effective to control the upper-limb exoskeleton, and provides a practical method by non-invasive EEG signal associated with human natural behavior for clinical applications.

    Scintigraphy with Ga-67 citrate routinely performed which showed an uptake in the stomach was reviewed retrospectively. There were 24 cases correlated ; 7 cases with malignant lymphoma in the stomach, 4 with gastric carcinoma, 2 with gastritis, 1 with abscess after gastroenterostomy and 8 with no disease detected. The Ga-uptake in the stomach in those was patterned to 4 groups. Rod and wall patterns were unlikely in malignant diseases of the stomach. On the other hand, focal or irregular uptake was commonly seen in malignant diseases of the stomach. Those Ga-uptake patterns may be useful to interprete complicated distribution of the radiogallium in the G.I. tracts of the left upper abdomen.

    Full Text Available History of present illness: A 40-year-old female presented to our ED with left upper abdominal pain and flank pain. The pain had begun suddenly 2 hours prior when she was reaching into a freezer to get a bag of frozen vegetables. She described the pain as sharp, constant, severe, and worse with movements and breathing. The pain radiated to the left shoulder. On review of systems, the patient had mild dyspnea and nausea. She denied fever, chills, headache, vision changes, vomiting, or urinary symptoms. Her medical history was notable for obstructive sleep apnea, gastroesophageal reflux disease, arthritis, fibromyalgia, depression, obesity, and idiopathic intracranial hypertension. For the latter, she had a VP (ventriculoperitoneal shunt placed 14 years prior to this visit. She had a history of 2 shunt revisions, the most recent 30 days before this ED visit. Significant findings: An immediate post-op abdominal x-ray performed after the patient’s VP shunt revision 30 days prior to this ED visit reveals the VP shunt tip in the mid abdomen. A CT of the abdomen performed on the day of the ED visit reveals the VP shunt tip interposed between the spleen and the diaphragm. Discussion: VP shunts have been reported to migrate to varied locations in the thorax and abdomen. Incidence of abdominal complications of VP shunt placement ranges from 10%-30%, and can include pseudocyst formation, migration, peritonitis, CSF ascites, infection, and viscus perforation. Incidence of distal shunt migration is reported as 10%, and most previously reported cases occurred in pediatric patients.1 A recent retrospective review cited BMI greater than thirty and previous shunt procedure as risk factors for distal shunt migration.2 The patient in the case presented had a BMI of 59 and 3 previous shunt procedures.

    In a retrospective study the results of abdominal computed tomography (CT) from 48 patients, who died of the complications of HIV infection, were compared with those obtained at autopsy. The CT diagnosis was confirmed at autopsy in 39 cases (81.3%). In nine patients CT results did not correlate with the postmortal findings. This was caused by lack of cooperation, cachexia and the time between the last CT study and the death of the patients. Nevertheless, CT with its standardised imaging planes is an important method for diagnosing and monitoring HIV-related diseases of the abdomen. (orig.) [de

    Purpose: The national diagnostic reference levels (NDRLs) is an efficient, concise and powerful standard for optimizing radiation protection of a patient. However, for each hospital the dose-reducing potential of focusing on establishment of local DRLs (LDRLs). A lot of study reported that Computed tomography exam contributed majority radiation dose in different medical modalities, therefore, routine abdomen CT exam was choose in initial pilot study in our study. Besides the mAs of routine abdomen CT exam was decided automatic exposure control by linear attenuation is relate to body shape of patient. In this study we would like to establish the local diagnostic reference levels of routine abdomen exam in computed tomography according to body weight of patient. Methods and Materials: There are two clinical CT scanners (a Toshiba Aquilion and a Siemens Sensation) were performed in this study. For CT examinations the basic recommended dosimetric quantity is the Computed Tomography Dose Index (CTDI). The patient sample involved 82 adult patients of both sexes and divided into three groups by their body weight (50–60 kg, 60–70 kg, 70–80 kg).Carried out the routine abdomen examinations, and all exposure parameters have been collected and the corresponding CTDIv and DLP values have been determined. The average values were compared with the European DRLs. Results: The majority of patients (75%) were between 50–70 Kg of body weight, the numbers of patient in each group of weight were 40–50:7; 50–60:29; 60–70:33; 70–80:13. The LDRLs in each group were 10.81mGy, 14.46mGy, 20.27mGy and 21.04mGy, respectively. The DLP were 477mGy, 630mGy, 887mGy and 959mGy, respectively. No matter which group the LDRLs were lower than European DRLs. Conclusions: We would like to state that this was a pioneer work in local hospital in Chiayi.

    Creatine (Cr) supplementation associated with resistance training produces greater muscular strength improvements in the upper compared with the lower body; however, no study has investigated if such region-specific results are seen with gains in muscle mass. We aimed to evaluate the effect of Cr supplementation in combination with resistance training on lean soft tissue changes in the upper and lower limbs and trunk in resistance-trained young adult men. In a randomized, double-blind and placebo-controlled design, 43 resistance-trained men (22.7 ± 3.0 years, 72.9 ± 8.7 kg, 177.9 ± 5.7 cm, 23.0 ± 2.5 kg/m 2 ) received either creatine (Cr, n = 22) or placebo (PLA, n = 21) over an 8-week study period. The supplementation protocol included a loading phase (7 days, four doses of 0.3 g/kg per day) and a maintenance phase (7 weeks, single dose of 0.03 g/kg per day). During the same period, subjects performed resistance training four times per week using the following two-way split routine: Monday and Thursday = pectoral, shoulders, triceps, and abdomen, Tuesday and Friday = back, biceps, thighs, and calves. Lean soft tissue of the upper limbs (ULLST), lower limbs (LLLST), and trunk (TLST) was assessed by dual-energy X-ray absorptiometry before and after the intervention. Both groups showed significant ( p hypertrophy (ULLST = 1.6 ± 3.0%; LLLST = 0.7 ± 2.8%; TLST = 0.7 ± 2.8%). Our results suggest that Cr supplementation can positively augment muscle hypertrophy in resistance-trained young adult men, particularly in the upper limbs.

    Full Text Available Abstract Background Ovarian vein thrombosis (OVT is a rare, but serious condition that affects mostly postpartum women. A high index of suspicion is required in order to diagnose this unusual cause of abdominal pain. Case presentation A 19-year-old woman at three days postpartum was admitted to our hospital because of severe right lower quandrant abdominal pain and fever 38.5'C. Physical examination revealed an acutely ill patient and right lower quadrant tenderness with positive rebound and Giordano signs. The patient underwent appendectomy which proved to be negative for acute appendicitis. Postoperatively fever and pain persisted and abdominal CT-scan with intravenous contrast agent demonstrated a thrombosed right ovarian vein. The patient was initiated on low-molecular weight heparin (LMWH and antibiotic treatment and a month later a new abdominal CT-scan showed a patent right ovarian vein. Discussion Pathophysiologically, OVT is explained by Virchow's triad, because pregnancy is associated with a hypercoagulable state, venous stasis due to compression of the inferior vena cava by the uterus and endothelial trauma during delivery or from local inflammation. Common symptoms and signs of OVT include lower abdomen or flank pain, fever and leukocytosis usually within the first ten days after delivery. The reported incidence of OVT ranges 0,05-0,18% of pregnancies and in most cases the right ovarian vein is the one affected. Anticoagulation and antibiotics is the mainstay of treatment of OVT. Complications of OVT include sepsis, extension of the thrombus to the inferior vena cava and renal veins, and pulmonary embolism. The incidence of pulmonary embolism is reported to be 13.2% and represents the main source of mortality due to OVT. Conclusions OVT is a rare condition, usually in the postpartum period. A high index of suspicion is required for the prompt diagnosis and management especially in cases that mimic acute abdomen.

    Full Text Available BACKGROUND The most common causes of the acute abdomen are acute appendicitis which may be perforated, typhoid ileal perforation, acute intestinal obstruction, gastroduodenal perforations, nonspecific abdominal pain, abdominal injuries, and acute cholecystitis. A summary of all the acute complications taken together will be the fact that all are associated with post-surgical complications. A sincere effort has been made to study the post-operative complications that a surgeon encounters while treating the acute abdomen cases. This study is intended to help the practising surgeons who deal with such complications. It also is intended to help the doctors who practice to identify such complications and thus refer the patients for immediate intervention. METHODS This study was conducted in the Department of General Surgery, Government Medical College, Nizamabad, Telangana. This study was done from June 2013 to May 2016. One hundred sixty patients who were admitted in the hospital after surgery for acute abdominal conditions were considered for the study. Thorough clinical examination was conducted and the complications that were encountered were noted and the complications were treated as per the need of the hour. The complications faced by the treating surgeon in each and every entity that was discussed earlier was duly noted and statistical analysis was conducted. All the statistical analysis was done using the latest SPSS software 2015 (California. RESULT In our study, the mean age of the study population was found to be 29.8 years. That means the majority of the patients who turn up in the Department of Emergency is young and generally in the third decade of life. In Acute Intestinal Obstruction and blunt abdominal injuries, significance of mortality is high (p<0.05. CONCLUSION The study was successful in proving that abdominal injuries are the main factors of causing morbidity and mortality in the younger generation. The surgical mode of

    The left sided gallbladder, being a rare occurrence, may create diagnostic problem especially when it becomes infected. Recently, we have experienced 2 cases of infection of left sided gallbladder at the Department of Radiology, St Mary's Hospital, Catholic Medical College. Case I was a 32-year-old housewife with dyspepsia, epigastric pain and recurring bouts of high fever of 2 months duration. Under the provisional diagnosis of liver abscess liver scan was performed which revealed well defined cold area in the left lobe supporting the provisional diagnosis. Tender cystic mass was aspirated and pus was drained. The injected air at the occasion of aspiration outlined well defined cystic structure. Because aspiration failed to control the symptoms, laparotomy was performed. Surgeon found a left sided gallbladder which was empyematous. Case II was a 38 year old business man admitted to the hospital because of tender ill defined mass in mid epigastrium. The patient was febrile (39.4 .deg. C) and anemic. An upper GI series disclosed an irregular filling defect involving the antrum of the stomach. The mass was primarily extrinsic but was closely fixed to the gastric wall. Surgical intervention revealed chronic cholecystitis and pericholecystitis with thick adhesion to the distal stomach.

  16. VALIDITY OF PARACENTESIS IN DIAGNOSING BLUNT TRAUMA ABDOMEN

    Full Text Available BACKGROUND Blunt abdominal trauma is a common case that comes to an emergency department and it is the most easily missed diagnosis resulting in catastrophic consequences. Delay in diagnosing a case is due to the nonspecific character of the symptoms with which it presents. Clinical signs that could be elicited in blunt trauma abdomen are equally nonspecific. Thus, to avoid delay and save the life of the patient, a doctor has to depend on various investigations to rule out blunt trauma abdomen. The modalities which help include paracentesis, diagnostic peritoneal lavage, Focused Abdominal Sonography for Trauma (FAST and ContrastEnhanced Computed Tomography (CECT. To choose the right investigation for the right patient helps in saving precious lives. Validity of each investigation, availability, condition of the patient are the main points to look into before deciding on the right investigative modality. Paracentesis is the simplest investigation that could be done in emergency department and also at the site of accident to triage the patient. Paracentesis has low sensitivity to detect blunt trauma. FAST is a better investigation with higher validity rates than paracentesis. This study aims to validate paracentesis, which is the simplest and commonest investigation used to identify blunt abdominal trauma. MATERIALS AND METHODS In this study, 106 patients who fulfilled the inclusion and exclusion criteria were followed up by detailed history, clinical examination, paracentesis and FAST to identify blunt abdominal trauma and then compared with a gold standard investigation, which was assigned as CECT for haemodynamically stable patients and laparotomy for haemodynamically unstable patients. Commonest organs injured in blunt trauma and their management was noted. Patients were followed up till discharge or death. Subsequently, the data were compiled using excel sheet and evaluated using tables and charts. RESULTS Paracentesis is found to have a

    Introduction. Meckel's diverticulitis is an extremely rare cause of an acute abdomen in pregnancy. Its clinical presentation tends to be rather unusual and therefore commonly delaying diagnosis. The surgical method of exploration can be either by laparoscopy or through an open incision. Case Report. We report a case of a 34-year-old, P1 with previous Caesarean section, who presented at 20 weeks with worsening right-sided abdominal pain, distention, and peritonism. Ultrasound scan showed an area of a possibly thickened loop of bowel inconsistent with an appendicitis. The findings at laparoscopy were purulent fluid in the pelvis, a congested appendix, and inflamed Meckel's diverticulum. An appendectomy and excision of the diverticulum was performed using stapler technique. Discussion. Meckel's diverticulitis in pregnancy can have nonspecific presentation and poses difficulties for preoperative diagnosis. Delay in diagnosis and management poses significant maternal and fetal risks. The use of laparoscopy if the gestational age and uterine size permit its use allows a thorough exploration of the abdominal cavity and management of rarer and unexpected pathology. Laparoscopic management of acute abdomen in the midtrimester of pregnancy has been found to be safe and effective.

    A 49 years old female patient entered the surgical department because of epigastric and ileocoecal pains with the symptoms of acute abdomen. A surgical intervention was performed because of supposed appendicitis, but it was not verified. During the surgical observation the patient was confused and negativistic so she was transferred to the psychiatric department. Because of loss of 20 kg weight, high blood sedimentation and anaemia she was sent to our department with the suspicion of an organic disease. A moderate exophthalmos, glittering eyes and Graefe's sign was noted, therefore hyperthyroidism was diagnosed, which was proved by Kocher's blood picture, low serum cholesterol, extremely high T3 and T4 level, and iodine storage diagram. The antithyreotic treatment resulted a dramatic improvement in the extremely serious moreover hopeless case and after a long-term treatment the patient became symptom-free without complaints. Later because of regression of hyperthyreoidism and the growing nodular goitre the patient was treated on two occasions with radioactive iodine. At present the patient is in remission.

  19. Search for W(prime) → tb resonances with left- and right-handed couplings to fermions

    International Nuclear Information System (INIS)

    2011-01-01

    We present a search for the production of a heavy gauge boson, W(prime), that decays to third-generation quarks, by the D0 Collaboration in p(bar p) collisions at √s = 1.96 TeV. We set 95% confidence level upper limits on the production cross section times branching fraction. For the first time, we set limits for arbitrary combinations of left- and right-handed couplings of the W(prime) boson to fermions. For couplings with the same strength as the standard model W boson, we set the following limits for M(W(prime)) > m(ν R ): M(W(prime)) > 863 GeV for purely left-handed couplings, M(W(prime)) > 885 GeV for purely right-handed couplings, and M(W(prime)) > 916 GeV if both left- and right-handed couplings are present. The limit for right-handed couplings improves for M(W(prime)) R ) to M(W(prime)) > 890 GeV.

    The eventration of diaphragm is usually found incidentally on chest X-ray or sometimes presented as acute gastric volvulus. However, colonic volvulus on splenic flexure area complicated by diaphragmatic eventration is extremely rare. A 25 year old man complained of upper abdominal pain for three days. He had a history of brain injury during infant period, and had epilepsy and mental retardation. Plain chest X-ray showed left diaphragmatic eventration and marked dilatation of colon on splenic flexure area which had not been changed for last three years. Barium enema showed bird beak appearance on distal colon near the splenic flexure. Colonoscopic reduction failed. After decompression with rectal and nasogastric tubes, colonic volvulus was relieved. To prevent the recurrence of volvulus, we performed segmental resection of left colon including splenic flexure area and repaired the left diaphragmatic eventration. After the operation, the patient had no further recurrent episode of volvulus although ileus persisted.

    Objective: To assess the usefulness of electron-beam CT (EBCT) in diagnosis of the viscero-atrial heterotaxy syndrome. Methods: Ten patients with the viscero-atrial heterotaxy syndrome were evaluated. The patients ranged in age from 7 months to 17 years (averaged 9.5 years). Five of the patients underwent EBCT contrast single slice mode while another 5 patients did continuous volume scan obtained from the superior aperture of thorax to the middle part of abdomen. All the patients had both angiocardiogram and echocardiogram, and 6 patients had operative outcomes. Results; (1) Eight patients with right atrial isomerism, bilaterally morphologic right atrial appendages, right lobe dominant symmetric liver, bilaterally epi-arterial bronchi, trilobed lungs, and total anomalous pulmonary venous connectional were clearly detected. Endocardial cushions defect, pulmonary stenosis, right-sided aortic arch and descending aorta were documented in 7 patients. Double outlet of right ventricle was imaged in 6 patients and hiatal hernia in 2 patients. Neither a spleen nor splenulus were found. (2) Two patients with left atrial isomerism, bilaterally morphologic left atrial appendages, left lobe dominant symmetric liver, bilaterally hyparterial bronchi, bilobed lungs, double outlet of right ventricle, pulmonary stenosis, interruption of inferior vena cave, right-sided aortic arch, and descending aorta were documented. Endocardial cushions defect was detected in 1 patient. Multiple spleens were demonstrated in the right upper abdomen in the 2 patients. (3) The number of abnormal observations detected by EBCT was 116, while that done by angiocardiogram and echocardiogram were 65 and 43 respectively. Conclusion: EBCT is a useful tool in the evaluation of patients with the syndrome of viscero-atrial heterotaxia

    2016-01-01

    to evaluate the ventilatory function by Peak Expiratory Flow (PEF) in the immediate pre and postoperative periods of patients undergoing elective surgical procedures in the upper abdomen. we conducted a prospective cohort study including 47 patients admitted to the Hospital Regional de Mato Grosso do Sul from July to December 2014, who underwent elective surgeries of the upper abdomen, and submiited to spirometric evaluation and measurement of PEF immediately before and after surgery. of the 47 patients, 22 (46.8%) were male and 25 (53.20%) female. The mean preoperative PEF was 412.1±91.7, and postoperative, 331.0±87.8, indicating significant differences between the two variables. Men had higher PEF values than women, both in the pre and postoperative periods. There was a reasonable inverse correlation between age and decreased PEF. Both situations showed statistical significance (pvalores de PFE do que o feminino, tanto no pré-cirúrgico quanto no pós-cirúrgico. Observou-se razoável correlação inversamente proporcional entre as variáveis idade e diminuição do PFE. Ambas as situações mostraram significância estatística (pvalores de PFE tanto no pré como no pós-operatório. O grupo composto por portadores de co-morbidades (HAS e/ou DM) apresentou menores valores de PFE tanto no pré como no pós-operatório (p=0,005). Em ambos os grupos, o pós-operatório determinou uma diminuição significativa do PFE (p<0,001). O tipo de cirurgia realizada e o tipo de anestesia não mostraram diferenças significantes em relação ao PFE. as variáveis mais implicadas na diminuição da função ventilatória, avaliadas através da PFE, foram: idade avançada, tabagismo e presença de comorbidades.

    Reconstruction of the whole body CT images by interpolation method was investigated by rapid scanning. Artronix 1120 with fixed collimator was used to obtain the CT images every 5 mm. X-ray source was circully movable to obtain perpendicular beam to the detector. A length of 150 mm was scanned in about 15 min., with the slice width of 5 mm. The images were reproduced every 7.5 mm, which was able to reduce every 1.5 mm when necessary. Out of 420 inspection in the chest, abdomen, and pelvis, 5 representative cases for which this method was valuable were described. The cases were fibrous histiocytoma of upper mediastinum, left adrenal adenoma, left ureter fibroma, recurrence of colon cancer in the pelvis, and abscess around the rectum. This method improved the image quality of lesions in the vicinity of the ureters, main artery, and rectum. The time required and exposure dose were reduced to 50% by this method. (Nakanishi, T.)

    Full Text Available A 64-year-old male presented to the emergency department (ED with near syncope and worsening left flank and shoulder pain. He had undergone a difficult colonoscopy two days prior due to a tortuous colon. Initial vital signs were normal. He looked uncomfortable and had significant left upper quadrant abdominal tenderness with guarding. Thirty minutes after ED arrival, his blood pressure dropped to 73/59 mmHg, requiring aggressive fluid resuscitation. Bedside focused assessment with sonography in trauma (FAST exam demonstrated free fluid in the abdomen with mixed echogenicity of the spleen, suggestive of splenic injury. Computed tomography (CT demonstrated a large subcapsular splenic hematoma with active extravasation and surrounding intraperitoneal free fluid (Figure, Video. He was admitted to the surgical intensive care unit. Hemorrhage continued after interventional radiology performed embolization of the splenic artery. He then required laparoscopic splenectomy on hospital day 2 to control bleeding. He subsequently did well and was discharged on hospital day 10.

    More than 10% of healthy population has one or more accessory spleens. The most common location is the hilum of the spleen or area near the tail of the pancreas. The radiological appearance of accessory spleens in oncologic patients who underwent splenectomy can be misinterpreted as a recurrence, especially in the case of compensatory growth of an accessory spleen in successive radiological examinations. We present the cases of three patients who underwent splenectomy for gastric carcinoid, gastric adenocarcinoma and cancer of the left adrenal gland, respectively. CT examination and/or PET-CT scan revealed suspicious findings in the left upper abdomen. In one patient, the dimensional increase of this finding in successive examinations was initially considered suggestive for cancer recurrence. Scintigraphy with 99m Tc-nanocolloid was able to confirm the presence of an accessory spleen in all these patients. Splenic scintigraphy is an economical, accessible and accurate tool in differential diagnosis of accessory spleens in patients after splenectomy

    Objective. To recognize intrathoracic abnormalities, including expansion or rupture of aortic aneurysms, as a source of acute onset vocal fold immobility. Methods. A case report and review of the literature. Results. An 85-year-old female with prior history of an aortic aneurysm presented to a tertiary care facility with sudden onset hoarseness. On laryngoscopy, the left vocal fold was immobile in the paramedian position. A CT scan obtained that day revealed a new, large hematoma surrounding the upper descending aortic stent graft consistent with an acute contained ruptured aortic aneurysm. She was referred to the emergency department for evaluation and treatment by vascular surgery. She was counseled regarding surgical options and ultimately decided not to pursue further treatment. Her vocal fold immobility was subsequently treated via office-based injection medialization two weeks after presentation and again 5 months after the initial injection which dramatically improved her voice. Follow-up CT scan at 8 months demonstrated a reduction of the hematoma. The left vocal cord remains immobile to date. Conclusion. Ortner's syndrome, or cardiovocal syndrome, is hoarseness secondary to left recurrent laryngeal nerve palsy caused by cardiovascular pathology. It is a rare condition and, while typically presenting gradually, may also present with acute symptomatology.

    We extend the scope of European palaeogenomics by sequencing the genomes of Late Upper Palaeolithic (13,300 years old, 1.4-fold coverage) and Mesolithic (9,700 years old, 15.4-fold) males from western Georgia in the Caucasus and a Late Upper Palaeolithic (13,700 years old, 9.5-fold) male from Switzerland. While we detect Late Palaeolithic–Mesolithic genomic continuity in both regions, we find that Caucasus hunter-gatherers (CHG) belong to a distinct ancient clade that split from western hunter-gatherers ~45 kya, shortly after the expansion of anatomically modern humans into Europe and from the ancestors of Neolithic farmers ~25 kya, around the Last Glacial Maximum. CHG genomes significantly contributed to the Yamnaya steppe herders who migrated into Europe ~3,000 BC, supporting a formative Caucasus influence on this important Early Bronze age culture. CHG left their imprint on modern populations from the Caucasus and also central and south Asia possibly marking the arrival of Indo-Aryan languages.

    Morris, Monica M.; Willett, Christopher G.

    1997-01-01

    Purpose: This study assesses the late renal function and complications following upper abdominal irradiation. Methods and Materials: Eighty-six adult patients were identified who were treated with curative intent to the upper abdomen, received greater than 50% unilateral kidney irradiation to doses of at least 26 Gy, and survived for 1 year or more. Following treatment, the clinical course, blood pressure, addition of anti-hypertensive medications, serum creatinine and creatinine clearance were determined. Creatinine clearance was calculated by the formula: creatinine clearance equals [(140 - age) x (weight in kilograms)] / (72 x serum creatinine), which has a close correlation to creatinine clearances measured by 24 hour urine measurement. The percent change in creatinine clearance from pre-treatment values was analyzed. Mean follow-up was 6.7 years. Seventeen patients were followed for 11 or more years. Results: Of the 16 patients with pre-radiotherapy hypertension, eight required an increase in the number of medications for control and eight required no change in medication. Twenty-one patients developed hypertension in follow-up, 15 of whom required no medication. One patient developed malignant hypertension on the basis of renal artery stenosis. Acute or chronic renal failure was not observed in any patient. The serum creatinine for all 86 patients prior to irradiation was below 2 mg/100 ml; in follow-up it rose to between 2-3 mg/100 ml in five patients. On univariate analysis, older patient age, female sex, pre-existing hypertension and initially abnormal renal function (creatinine clearance <90mg/ml) were significantly correlated with later poor creatinine clearance (<50 mg/ml). Conclusions: After significant unilateral kidney irradiation, patients demonstrated a laboratory trend to increased creatinine and decreased creatinine clearance. With long-term follow-up, these physiologic changes did not appear to translate into a clinically relevant alteration in

    An 18 year old male with a history of prune belly syndrome (PBS) presented with acute abdominal pain and palpable left upper quadrant mass. Computed tomography (CT) of the abdomen revealed a medialized spleen with a "whirl sign" in the splenic vessels, consistent with splenic torsion. Coincidentally, the small bowel was also noted to be on the right side of the abdomen, while the colon was located on the left, indicative of malrotation. Emergent diagnostic laparoscopy confirmed splenic torsion and intestinal malrotation. Successful laparoscopic reduction of the splenic torsion was achieved, however, conversion to an open procedure by a vertical midline incision was necessary owing to the patient's unique anatomy. Open splenopexy with a mesh sling and Ladd's procedure were subsequently performed. Malrotation and wandering spleen are known, rare associated anomalies in PBS; however, both have not been reported concurrently in a patient with PBS in the literature. In patients with PBS, acute abdominal pain, and an abdominal mass, high clinical suspicion for gastrointestinal malformations and prompt attention can result in spleen preservation and appropriate malrotation management. We present a case of a teenager who presented with a history of PBS, acute abdominal pain, and a palpable abdominal mass. The patient was found to have splenic torsion and intestinal malrotation. The clinical findings, diagnostic imaging, and surgical treatment options of splenic torsion are reviewed. Copyright © 2013 Elsevier Inc. All rights reserved.

    The Performance of the Upper Limb scale was developed as an outcome measure specifically for ambulant and non-ambulant patients with Duchenne muscular dystrophy and is implemented in clinical trials needing longitudinal data. The aim of this study is to determine whether this novel tool correlates with functional ability using pulmonary function test, cardiac function test and Egen Klassifikation scale scores as clinical measures. In this cross-sectional study, 43 non-ambulatory Duchenne males from ages 10 to 30 years and on long-term glucocorticoid treatment were enrolled. Cardiac and pulmonary function test results were analyzed to assess cardiopulmonary function, and Egen Klassifikation scores were analyzed to assess functional ability. The Performance of the Upper Limb scores correlated with pulmonary function measures and had inverse correlation with Egen Klassifikation scores. There was no correlation with left ventricular ejection fraction and left ventricular dysfunction. Body mass index and decreased joint range of motion affected total Performance of the Upper Limb scores and should be considered in clinical trial designs. Copyright © 2016 Elsevier B.V.

  14. Magnetic resonance imaging of the abdomen and pelvis

    International Nuclear Information System (INIS)

    1989-01-01

    Magnetic resonance imaging (MRI) of the abdomen presents greater inherent difficulties than other anatomic regions. However, new techniques now allow imaging comparable in quality to computed tomography (CT). Magnetic resonance imaging offers the advantages of greater tissue contrast, multiplanar imaging, and lack of ionizing radiation or risk of toxic reactions from iodinated contrast media. Its use remains limited by high cost, limited availability, lack of a bowel contrast agent, and long imaging time, which some patients cannot tolerate. In many areas of abdominal imaging, MRI is now comparable to CT, but because of the greater availability and lesser cost, CT remains the procedure of choice. Magnetic resonance imaging is more accurate for staging neoplasms of the liver, adrenal glands, kidneys, bladder, prostate, uterus, and cervix and may aid in diagnosis of hepatic, adrenal, and uterine masses. In selected patients, especially those in whom CT is inconclusive or those who cannot tolerate iodinated contrast material, MRI can provide valuable information. Development of faster scanning techniques and MRI contrast agents and wider availability will probably increase the usefulness of abdominal MRI. At this time, MRI complements other abdominal imaging procedures. In a small number of patients, however, it can provide unique information in a virtually risk-free manner

    The kidneys are a principal dose-limiting organ in radiotherapy for upper abdominal cancers. The current understanding of kidney radiation dose response is rudimentary. More precise dose-volume response models that allow direct correlation of delivered radiation dose with spatio-temporal changes in kidney function may improve radiotherapy treatment planning for upper-abdominal tumours. Our current understanding of kidney dose response and tolerance is limited and this is hindering efforts to introduce advanced radiotherapy techniques for upper-abdominal cancers, such as intensity-modulated radiotherapy (IMRT). The aim of this study is to utilise radiotherapy and combined anatomical/functional imaging data to allow direct correlation of radiation dose with spatio-temporal changes in kidney function. The data can then be used to develop a more precise dose-volume response model which has the potential to optimise and individualise upper abdominal radiotherapy plans. The Radiotherapy of Abdomen with Precise Renal Assessment with SPECT/CT Imaging (RAPRASI) is an observational clinical research study with participating sites at Sir Charles Gairdner Hospital (SCGH) in Perth, Australia and the Peter MacCallum Cancer Centre (PMCC) in Melbourne, Australia. Eligible patients are those with upper gastrointestinal cancer, without metastatic disease, undergoing conformal radiotherapy that will involve incidental radiation to one or both kidneys. For each patient, total kidney function is being assessed before commencement of radiotherapy treatment and then at 4, 12, 26, 52 and 78 weeks after the first radiotherapy fraction, using two procedures: a Glomerular Filtration Rate (GFR) measurement using the 51 Cr-ethylenediamine tetra-acetic acid (EDTA) clearance; and a regional kidney perfusion measurement assessing renal uptake of 99m Tc-dimercaptosuccinic acid (DMSA), imaged with a Single Photon Emission Computed Tomography / Computed Tomography (SPECT/CT) system.

    To determine the relationship of increasing body mass index (BMI) and abdominal fat on the effective dose acquired from computed tomography (CT) abdomen and pelvis scans. Over 6 months, dose-length product and total milliamp-seconds (mAs) from routine CT abdomen and pelvis scans of 100 patients were recorded. The scans were performed on a 64-slice CT scanner by using an automatic exposure control system. Effective dose (mSv) based on dose-length product, BMI, periumbilical fat thickness, and intra-abdominal fat were documented for each patient. BMI, periumbilical fat thickness, and intra-abdominal fat were compared with effective dose. Thirty-nine men and 61 women were included in the study (mean age, 56.3 years). The mean BMI was 26.2 kg/m(2). The mean effective dose was 10.3 mSv. The mean periumbilical fat thickness was 2.4 cm. Sixty-five patients had a small amount of intra-abdominal fat, and 35 had a large amount of intra-abdominal fat. The effective dose increased with increasing BMI (P abdominal fat (P abdominal fat significantly increases the effective dose received from CT abdomen and pelvis scans.

    To evaluate the long-term prognostic value of risk scores in the setting of drug-eluting stent (DES) implantation for uLMCA. Data on the prognostic value of novel risk scores developed to select the most appropriate revascularization strategy in patients undergoing DES implantation for uLMCA disease are relatively limited. The study represents a patient-level pooled analysis of the ISAR-LEFT-MAIN (607 patients randomized to paclitaxel-eluting or sirolimus-eluting stents) and the ISAR-LEFT-MAIN-2 (650 patients randomized to everolimus-eluting or zotarolimus-eluting stents) randomized trials. The Syntax Score (SxScore) as well the Syntax Score II (SS-II), the EuroSCORE and the Global Risk Classification (GRC) were calculated. The primary outcome was all-cause mortality. At a mean follow-up of 3 years there were 160 deaths (12.7%). The death-incidence was significantly higher in the upper tertiles than in the intermediate or lower ones for all risk scores (log-rank test P risk scores were able to stratify the mortality risk at long-term follow-up. EuroSCORE was the only risk score that significantly improved the discriminatory power of a multivariable model to predict long-term mortality. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    An open abdomen complicated with small-bowel fistulae becomes a complex wound for local infection, systemic sepsis and persistent soiling irritation by intestinal content. While controlling the fistulae drainage, protecting surrounding skin, healing the wound maybe a challenge. In this paper we described a 68-year-old female was admitted to emergency surgery in general surgery department with severe abdomen pain. Resection part of the injured small bowel, drainage of the intra-abdominal abscess, and fashioning of a colostomy were performed. She failed to improve and ultimately there was tenderness and lot of pus under the skin around the fistulae. The wound started as a 3-cm lesion and progressed to a 6 ×13  (78 cm) around the stoma. In our case we present a novel device for managing colostomy wound combination with negative pressure wound therapy. This tube allows for an effective drainage of small-bowel secretion and a safe build-up of granulation tissue. Also it could be a barrier between the bowel suction point and foam. Management of open abdomen wound involves initial dressing changes, antibiotic use and cutaneous closure. When compared with traditional dressing changes, the NPWT offers several advantages including increased granulation tissue formation, reduction in bacterial colonization, decreased of bowel edema and wound size, and enhanced neovascularization.

    Full Text Available Introduction. Meckel’s diverticulitis is an extremely rare cause of an acute abdomen in pregnancy. Its clinical presentation tends to be rather unusual and therefore commonly delaying diagnosis. The surgical method of exploration can be either by laparoscopy or through an open incision. Case Report. We report a case of a 34-year-old, P1 with previous Caesarean section, who presented at 20 weeks with worsening right-sided abdominal pain, distention, and peritonism. Ultrasound scan showed an area of a possibly thickened loop of bowel inconsistent with an appendicitis. The findings at laparoscopy were purulent fluid in the pelvis, a congested appendix, and inflamed Meckel’s diverticulum. An appendectomy and excision of the diverticulum was performed using stapler technique. Discussion. Meckel’s diverticulitis in pregnancy can have nonspecific presentation and poses difficulties for preoperative diagnosis. Delay in diagnosis and management poses significant maternal and fetal risks. The use of laparoscopy if the gestational age and uterine size permit its use allows a thorough exploration of the abdominal cavity and management of rarer and unexpected pathology. Laparoscopic management of acute abdomen in the midtrimester of pregnancy has been found to be safe and effective.

    The patient had esthetically unacceptable upper left central incisor crowns. The case was restored using Empress (staining technique) for the upper central incisors on both sides. In making all-ceramic crowns, it is necessary to reproduce the shape and color near to those of the natural tooth. We should not overlook the importance of diagnostic waxing-up, provisional restoration, tooth preparation, gingival retraction and others, to achieve excellent appearance, function and biocompatibility. It is effective to use the staining technique for an anterior tooth crown in order to obtain esthetically satisfactory results by the papilla being present in such cases as the distance from the base of the contact point to the crest of the bone is 5 mm or less.

    Full Text Available Neblinichthys brevibracchium and N. echinasus are new sympatric species from upland tributaries of the Mazaruni River (Essequibo River basin of Guyana. These two new species are the first Neblinichthys reported from Guyana. Adult males of both new species have short pectoral-fin spines and several series of hypertrophied odontodes covering the entire dorsal surface and along the entire edge of the snout. They are distinguished from each other by dorsal-fin base length/standard length (18.1-22.8% in N. brevibracchium vs. 24.3-27.0% in N. echinasus, dorsal-anal distance/SL (13.7-18.3% in N. brevibracchium vs. 11.9-12.5% in N. echinasus, by having the snout decreasing in steep arc just anterior to eyes and then flattening in area anterior of nares in N. brevibracchium vs. the snout tapering shallowly and continuously from eyes to snout tip in N. echinasus; and by having the adpressed dorsal fin reaching the anterior preadipose plate in N. brevibracchium (vs. not reaching anterior preadipose plate in N. echinasus. They are distinguished from all congeners by lacking odontodes on the opercle (vs. odontodes present; and by completely lacking an iris operculum (vs. congeners with small iris operculum present or at least dorsal portion of iris flat instead of rounded. Neblinichthys echinasus and N. brevibracchium differ from all congeners by having a spotted or vermiculated pigment pattern on the abdomen (vs. abdomen plain; in N. echinasus the abdomen is darkly pigmented with bold white spots and in Neblinichthys brevibracchium the abdomen is light-colored with gray spots and vermiculations. Neblinichthys brevibracchium and N. echinasus differ from N. roraima by having one to two preadipose plates (vs. four or more. New observations revealed Neblinichthys roraima and N. yaravi to be distinct, with N. roraima having four or more preadipose plates and N. yaravi having one or two. Both are present in the upper río Caroní, an Orinoco tributary that drains

    Full Text Available Adrenal myelolipoma is an unusual, benign and biochemically inactive tumor that is composed of mature adipose and hematopoietic tissue. It is usually diagnosed accidentally and nowadays much more frequently because of widespread use of ultrasonography, computed tomography (CT and magnetic resonance imaging. Adrenal myelolipoma is usually unilateral and asymptomatic, though known to be associated with obesity, hypertension, endocrinological disorders and some malignancies. We report herein two cases of right-sided giant adrenal myelolipoma diagnosed by multidetector-row CT. One patient was symptomatic because of a large mass in the right upper abdomen, which on imaging with CT was seen to be right adrenal myelolipoma. Another patient had a large left side Bochdalek hernia and right adrenal myelolipoma was incidentally discovered on CT.

    Full Text Available Pulmonary vein varix is an unusual cause of a mediastinal mass on a chest radiograph. It may be found as an isolated malformation or as a sequela of pulmonary venous hypertension. We encountered a case presenting with left hemiparesis and a past medical history of rheumatic heart disease. The chest radiograph revealed a well-defined mediastinal mass that turned out to be a hugely dilated pulmonary vein on contrast enhanced computed tomography of the chest. The computed tomography of the brain and upper abdomen revealed bilateral cerebral infarction and splenic infarction. In the literature, one-third of the reported cases of pulmonary vein varix are acquired secondary to mitral valve disease.

    To discuss the application of the degree of portal systemic shunting in assessing the upper gastrointestinal bleeding in patients with hepatic schistosomiasis. Thirty-three patients with upper gastrointestinal bleeding caused by hepatic schistosomiasis (a bleeding group) and 29 schistosomiasis cirrhosis patients without bleeding (a non-bleeding group) were enrolled as investigation subjects in Jinshan Hospital. The subjects were scanned by the 128 abdominal slice spiral CT. The portal systemic shunting vessels were reconstructed by using thin slab maximum intensity projection (TSMIP) and multiplanar reconstruction (MPR). The degrees of the shunting vessels of the subjects were evaluated and compared, and the relationship between upper gastrointestinal bleeding and the degree of the shunting was analyzed. In the bleeding group, the occurrence rates of the shunting vessels were found as follows: 86.4% in left gastric varices, 68.2% in short gastric varices, 50.0% in esophageal varices, 50.0% in para-esophageal varices, 37.9% in gastric varices, 69.7% in gastric-renal varices, 51.5% in spleen-renal varices, 25.8% in abdominal wall varices, 15.2% in omentum varices, 63.6% in para-splenic varices, 34.8% in umbilical varices, 40.9% in retroperitoneal-paravertebral varices, and 36.4% in mesenteric varices. In the bleeding group, the occurrence rates and the degree of shunt were significantly higher than those in the non-bleeding group in esophageal varices, esophageal vein, left gastric vein and gastric varices (all P upper gastrointestinal bleeding in patients with hepatic schistosomiasis. The patents with higher degree of the shunting vessels have a higher risk of gastrointestinal bleeding.

    Although adhesions account for more than 70% of small bowel obstruction (SBO), they are thought to be less likely aetiologies in patients without previous abdominal surgery. Expedient surgery has historically been advocated as prudent management in these patients. Emerging evidence appears to challenge such a dogmatic approach. A retrospective analysis was performed in all SBO patients with a virgin abdomen admitted between January 2012 and August 2014. Patients with obstruction secondary to abdominal wall hernias were excluded. Patient demographics, clinical presentation, management strategy and pathology involved were reviewed. A total of 72 patients were included in the study. The majority of patients were males (66.7%), with a median age of 58 years (range: 23-101). Abdominal pain (97%) and vomiting (86%) were the most common presentations while abdominal distention (60%) and constipation (25%) were reported less frequently. Adhesions accounted for the underlying cause in 44 (62%) patients. Other aetiologies included gallstone ileus (n = 5), phytobezoar (n = 5), intussusception (n = 4), internal herniation (n = 4), newly diagnosed small bowel tumour (n = 3), mesenteric volvulus (n = 3), stricture (n = 3) and Meckel's diverticulum (n = 1). Twenty-nine (40%) patients were successfully managed conservatively while the remaining 43 (60%) underwent surgery. The intraoperative findings were in concordance with the preoperative computed tomography scan in 76% of cases. Adhesions remain prevalent despite the absence of previous abdominal surgery. Non-operative management is feasible for SBO in a virgin abdomen. Computed tomography scan can be a useful adjunct in discerning patients who may be treated non-operatively by elucidating the underlying cause of obstruction. © 2016 Royal Australasian College of Surgeons.

    Full Text Available Objective. This study reports a case in which elastic band use culminated in the loss of the incisors. Case Report. An 11-year-old white girl was seen complaining of pain, with purulent discharge and severe tooth mobility. The bone destruction detected radiographically in the region, despite its single location and absence in posterior quadrants of the maxilla and/or mandible, was similar to that observed in Langerhans cell disease. To our surprise, an elastic band involving the midportion of the roots of the two upper central incisors was found during biopsy. The debris was removed and a metal wire was placed in permanent maxillary right and left incisors. The patient was followed up, but no improvement in tooth mobility was observed. Bone loss increased, and internal resorption and root exposure occurred, which culminated in the extraction of permanent maxillary right and left incisors. Conclusion. The present case highlights the fact that professionals sometimes are confronted by anamnestic reports never seen before.

    Full Text Available Hand dominance is defined as a proneness to use one hand rather than another in performing the majority of activities and this is the most obvious example of cerebral lateralization and an exclusive human characteristic. Left-handed people comprise 6-14% of the total population, while in Serbia, this percentage is 5-10%, moving from undeveloped to developed environments, where a socio-cultural pressure is less present. There is no agreement between investigators who in fact may be considered a left-handed person, about the percentage of left-handers in the population and about the etiology of left-handedness. In the scientific literature left-handedness has been related to health disorders (spine deformities, immunological disorders, migraine, neurosis, depressive psychosis, schizophrenia, insomnia, homosexuality, diabetes mellitus, arterial hypertension, sleep apnea, enuresis nocturna and Down Syndrome, developmental disorders (autism, dislexia and sttutering and traumatism. The most reliable scientific evidences have been published about the relationship between left-handedness and spinal deformities in school children in puberty and with traumatism in general population. The controversy of other results in up-to-now investigations of health aspects of left-handedness may partly be explained by a scientific disagreement whether writing with the left hand is a sufficient criterium for left-handedness, or is it necessary to investigate other parameters for laterality assessment. Explanation of health aspects of left-handedness is dominantly based on Geschwind-Galaburda model about 'anomalous' cerebral domination, as a consequence of hormonal disbalance. .

    Full Text Available Intramural hematoma is a clinical situation which is secondary to anticoagulant therapy. In this study, a chronic atrial fibrilation patient taking anticoagulant, had perforation at rectosigmoid region which was secondary to intramural hematoma, is presented. Our case was a eighty-three-year-old male presented with acute abdomen at emergency room. In computerized tomography, intraabdominal free air and hematoma at rectosigmoid region were seen. Due to these, the decision of immidiate exploration was made. This should be noted that intramural hematoma can emerge in patientd on anticoagulant theraphy without trauma. Additionally, it shold be considered that intramural hematoma can lead to lethal complication such as perforation.

    2010-08-01

    Full Text Available Abstract Introduction We report an unusual presentation of a small hepatic cyst causing cholangitis. Case presentation A 70-year-old Asian man was hospitalized for aggravated chronic pain in the right upper portion of his abdomen. Fever developed after admission. Laboratory tests revealed elevated hepatobiliary enzymes, inflammatory markers and carbohydrate antigen 19-9 without hyperbilirubinemia. Ultrasound and computed tomography demonstrated dilatation of the left intra-hepatic bile ducts. Endoscopic retrograde cholangiopancreatography showed that the right intra-hepatic bile ducts were normally filled with contrast medium, but the left intra-hepatic bile ducts were not seen in the confluence. A left hepatectomy was performed because a hidden malignancy could not be excluded. The surgical findings showed no tumor around the bile duct but rather a 2 cm cyst in segment four of Couinaud's category of the liver around the hilum. The pathology report was a solitary non-parasitic hepatic cyst compressing the bile duct. Conclusion A very small solitary hepatic cyst might cause hepatic duct stricture if it is located near the hepatic hilum, and should be considered in the differential diagnosis of a hepatic duct stricture.

    Introduction: Malignancy is a late cause of mortality in heart transplant recipients. It is unknown if screening computed tomography scan would lead to early detection of such malignancies or serious vascular anomalies post heart transplantation. Methods: This is a single center observational study of patients undergoing surveillance computed tomography of chest, abdomen and pelvis atleast 5 years after transplantation. Abnormal findings, included pulmonary nodules, lymphadenopathy and intra-thoracic and intra-abdominal masses and vascular anomalies such as abdominal aortic aneurysm. The clinical follow up of each of these major abnormal findings is summarized. Results: A total of 63 patients underwent computed tomography scan of chest, abdomen and pelvis at least 5 years after transplantation. Of these, 54 (86%) were male and 9 (14%) were female. Mean age was 52 ± 9.2 years. Computed tomography revealed 1 lung cancer (squamous cell) only. Non specific pulmonary nodules were seen in 6 patients (9.5%). The most common incidental finding was abdominal aortic aneurysms (N = 6 (9.5%)), which necessitated follow up computed tomography (N = 5) or surgery (N = 1). Mean time to detection of abdominal aortic aneurysms from transplantation was 14.6 ± 4.2 years. Mean age at the time of detection of abdominal aortic aneurysms was 74.5 ± 3.2 years. Conclusion: Screening computed tomography scan in patients 5 years from transplantation revealed only one malignancy but lead to increased detection of abdominal aortic aneurysms. Thus the utility is low in terms of detection of malignancy. Based on this study we do not recommend routine computed tomography post heart transplantation.

    The objective of this study was to compare the image quality of a dual-energy nonlinear image blending technique at reduced load of contrast medium with a simulated 120-kVp linear blending technique at a full dose during portal venous phase MDCT of the abdomen. Forty-five patients (25 men, 20 women; mean age, 65.6 ± 9.7 [SD] years; mean body weight, 74.9 ± 12.4 kg) underwent contrast-enhanced single-phase dual-energy CT of the abdomen by a random assignment to one of three different contrast medium (iomeprol 400) dose injection protocols: 1.3, 1.0, or 0.65 mL/kg of body weight. The contrast-to-noise ratio (CNR) and noise at the portal vein, liver, aorta, and kidney were compared among the different datasets using the ANOVA. Three readers qualitatively assessed all datasets in a blinded and independent fashion. Nonlinear blended images at a 25% reduced dose allowed a significant improvement in CNR (p < 0.05 for all comparisons), compared with simulated 120-kVp linear blended images at a full dose. No statistically significant difference existed in CNR and noise between the nonlinear blended images at a 50% reduced dose and the simulated 120-kVp linear blended images at a full dose. Nonlinear blended images at a 50% reduced dose were considered in all cases to have acceptable image quality. The dual-energy nonlinear image blending technique allows reducing the dose of contrast medium up to 50% during portal venous phase imaging of the abdomen while preserving image quality.

    It is extremely rare to encounter intracranial foreign bodies caused by penetrating injuries other than gunshot wounds or low-velocity wounds. We present a case describing a 5-year-old girl with metallic foreign bodies in the medulla oblongata, cervical spinal cord, and abdomen. The foreign bodies may have been there and remained silent for several years until the patient developed nausea and vomiting that persisted for 3 months. A craniotomy and a laparotomy were performed after a thorough discussion. Five pieces of metallic foreign bodies were removed, and the patient had a good outcome. Despite the precarious location of the needles in the medulla oblongata and cervical spinal cord, this rare case supports the use of surgery to remove the foreign bodies.

    Full Text Available Background: Patients with Sickle cell trait (SCT are usually asymptomatic. They are usually unaware of their condition unless they have a family history. There are specific situations, where these people suffer from the effects of sickle cell trait. Splenic syndrome at high altitude is one of the specific problems. It is usually seen after a patient with SCT has been inducted to high altitude like in case of mountaineers and military personnel deployed in high altitude warfare. Pain abdomen due to splenic infarction in individuals with SCT is one of the manifestations. These patients, if diagnosed in time, they can be spared from unnecessary surgical interventions. We present herewith our experience of splenic infarction due to SCT in high altitude and their management.

    In the absence of visual feedback, the perceived orientation of the fingers is systematically biased. In right-handers these biases are asymmetrical between the left and right hands in the horizontal plane and may reflect common functional postures for the two hands. Here we compared finger orientation perception in right- and left-handed participants for both hands, across various hand positions in the horizontal plane. Participants rotated a white line on a screen optically superimposed over their hand to indicate the perceived position of the finger that was rotated to one of seven orientations with the hand either aligned with the body midline, aligned with the shoulder, or displaced by twice the shoulder-to-midline distance from the midline. We replicated the asymmetric pattern of biases previously reported in right-handed participants (left hand biased towards an orientation ~30° inward, right hand ~10° inward). However, no such asymmetry was found for left-handers, suggesting left-handers may use different strategies when mapping proprioception to body or space coordinates and/or have less specialization of function between the hands. Both groups' responses rotated further outward as distance of the hand from the body midline increased, consistent with other research showing spatial orientation estimates diverge outward in the periphery. Finally, for right-handers, precision of responses was best when the hand was aligned with the shoulder compared to the other two conditions. These results highlight the unique role of hand dominance and hand position in perception of finger orientation, and provide insight into the proprioceptive position sense of the upper limbs.

    Advances in neuroimaging have enabled the mapping of white matter connections across the entire brain, allowing for a more thorough examination of the extent of white matter disconnection after stroke. To assess how cortical disconnection contributes to motor impairments, we examined the relationship between structural brain connectivity and upper and lower extremity motor function in individuals with chronic stroke. Forty-three participants [mean age: 59.7 (±11.2) years; time poststroke: 64.4 (±58.8) months] underwent clinical motor assessments and MRI scanning. Nonparametric correlation analyses were performed to examine the relationship between structural connectivity amid a subsection of the motor network and upper/lower extremity motor function. Standard multiple linear regression analyses were performed to examine the relationship between cortical necrosis and disconnection of three main cortical areas of motor control [primary motor cortex (M1), premotor cortex (PMC), and supplementary motor area (SMA)] and motor function. Anatomical connectivity between ipsilesional M1/SMA and the (1) cerebral peduncle, (2) thalamus, and (3) red nucleus were significantly correlated with upper and lower extremity motor performance (P ≤ 0.003). M1-M1 interhemispheric connectivity was also significantly correlated with gross manual dexterity of the affected upper extremity (P = 0.001). Regression models with M1 lesion load and M1 disconnection (adjusted for time poststroke) explained a significant amount of variance in upper extremity motor performance (R 2  = 0.36-0.46) and gait speed (R 2  = 0.46), with M1 disconnection an independent predictor of motor performance. Cortical disconnection, especially of ipsilesional M1, could significantly contribute to variability seen in locomotor and upper extremity motor function and recovery in chronic stroke.

    Automatic localization of organs and other structures in medical images is an important preprocessing step that can improve and speed up other algorithms such as organ segmentation, lesion detection, and registration. This work presents an efficient method for simultaneous localization of multiple structures in 3D thorax-abdomen CT scans. Our approach predicts the location of multiple structures using a single multi-label convolutional neural network for each orthogonal view. Each network takes extra slices around the current slice as input to provide extra context. A sigmoid layer is used to perform multi-label classification. The output of the three networks is subsequently combined to compute a 3D bounding box for each structure. We used our approach to locate 11 structures of interest. The neural network was trained and evaluated on a large set of 1884 thorax-abdomen CT scans from patients undergoing oncological workup. Reference bounding boxes were annotated by human observers. The performance of our method was evaluated by computing the wall distance to the reference bounding boxes. The bounding boxes annotated by the first human observer were used as the reference standard for the test set. Using the best configuration, we obtained an average wall distance of 3.20~+/-~7.33 mm in the test set. The second human observer achieved 1.23~+/-~3.39 mm. For all structures, the results were better than those reported in previously published studies. In conclusion, we proposed an efficient method for the accurate localization of multiple organs. Our method uses multiple slices as input to provide more context around the slice under analysis, and we have shown that this improves performance. This method can easily be adapted to handle more organs.

    We describe a coaxial introducer provided with an additional blunt-tip stylet that allows safe access to difficult-to-reach lymph nodes in the chest, abdomen, and pelvis under CT control. Once the thoracic, abdominal, or pelvic wall is crossed by the introducer fitted with the sharp-tip stylet, the blunt-tip stylet replaces the sharp stylet for further progression in the fat toward the target. The soft-tip stylet carries a smaller risk of inadvertent perforation displacing vital structures.

    Full Text Available OBJECTIVES: Vascular injuries to the upper extremities requiring surgical repair are common after accidents. However, neither postoperative functionality nor hemodynamic status of the extremity are routinely described. We evaluated the postoperative functional and hemodynamic status of patients with vascular traumas in the upper extremities. METHODS: 26 patients who suffered penetrating vascular traumas in the upper extremities from November 2008 to December 2011 were retrospectively evaluated. Data on first approach, surgical technique employed and early postoperative outcomes were recorded. Further data on the post-discharge period, including clinical functional status of the arm, Doppler ultrasonography and brachial-brachial index were also evaluated. RESULTS: Average follow up was 33.5±10.8 months. Right (1.05±0.09 and left (1.04±0.08 brachial indexes were measured during follow up,. Doppler ultrasonography showed arterial occlusion in 4 patients (15%. Near-normal brachial-brachial indexes was observed in all four of these patients with occlusion of one of the upper extremity arteries, even though they exhibited limited arm function for daily work. CONCLUSIONS: Evaluation of the postoperative outcomes of this small series of patients with penetrating vascular traumas in the upper extremity revealed that 15% of them suffered occlusion of one artery of the upper extremity. Artery occlusion did not correlate with brachial-brachial Doppler index, probably due to rich collateral circulation, but occlusion was associated with an extremity that was dysfunctional for the purposes of daily work. The result of the brachial-brachial index does not therefore correlate with functionality.

    Myocardial viability was determined by using postsystolic shortening (PSS) as an index, as obtained by cardiac blood pool scintigraphy with Tc-99m HSA. The findings were compared with those of thallium-201 myocardial SPECT. The study population was comparised of 41 patients with single blood vessel disease in the left anterior descending artery (34 with old myocardial infarction and 7 with effort angina pectoris). Left ventricular area was divided into 6 segments, and global and regional left ventricular blood volume curves were obtained. Delayed end-systole was the most common in the apex (41%), followed by the upper septum (37%) and lower septum (10%). PSS resulting from delayed end-systole was seen in 36 areas. PSS/end-diastolic volume (EDV) and PSS/systolic volume (SV) were obtained by adjusting end-diastolic and stroke counts, respectively. Thallium-201 myocardial SPECT images were divided into 5 segments to obtain defect score (DS) for visual Tl uptake. Both PSS/EDV and PSS/SV were greater in association with more delayed end-systole, greater DS, and lower reginal ejection fraction. Areas showing greater PSS were associated with less myocardial viability, as observed on Tl myocardial SPECT images. Thus, PSS seemed to reflect the degree of myocardial necrosis within the region of interest. (N.K.)

    Despite the numerous advances in recent years, severe abdominal sepsis (with associated organ failure associated with infection) remains a serious, life-threatening condition with a high mortality rate. OA is a viable alternative to the previously used scheduled repeat laparotomy or continuous peritoneal lavage. The use of Negative Pressure Wound Therapy (NPWT) has been described as a successful method of management of the open abdomen. Adding instillation of saline solution to NPWT in a programmed and controlled manner, could offer the clinician an additional tool for the management of complex septic abdomen. To explore if the concept of active two-way therapy (Negative pressure wound therapy with instillation or NPWT-I) yields superior control of underlying, life-threatening abdominal infections and its effects on survival and morbidity in patients with severe abdominal sepsis when management with an open abdomen is required. A retrospective review of 48 patients with severe abdominal sepsis, who were managed with and open abdomen and NPWT-I was performed. NPWT-I was initiated utilizing the same parameters on all patients, this consisted of cycles of instillation of saline solution, which was removed through negative pressure after a short dwell period. We observed the effects on primary fascia closure rate, mortality, hospital and SICU length of stay and associated complications. Our patient group consisted of 20 (42%) males and 28 (58%) females. Average age was 48 years. Mortality in these patients was attributed to pulmonary embolism (n=1), acute renal failure (n=2) and cardiopulmonary arrest (n=1). Average total hospital stay was 24days, and stay in the SICU (n=26) averaged 7.5days. No acute complications related to the NPWT-I. All patients presenting with abdominal compartment syndrome resolved after initiation of the NPWT-I. A total of 46 patients (96%) patients achieved fascia closure after NPWT-I therapy after an average of 6days. Four patients (8%) died

    Management of patients with brachial plexus injuries requires a team approach so that all aspects of their care are addressed simultaneously. This report examines elective amputation and prosthetic rehabilitation in a patient with brachial plexus avulsion of the left arm. The best possibility for good prosthetic rehabilitation is the early application of prosthetic devices with intensive occupational therapy. Using this type of approach, we have achieved significant improvement in amputation rehabilitation of upper extremity amputees treated with immediate postoperative conventional electric and myoelectric prostheses.

    The authors established a comparative relationship between accuracy of measurement of pulmonary flow and extent of vascular widening in 72 children with Left-Right shunt vitiae; this accuracy of pulmonary flow measurement had been subjectively estimated by 4 investigators without knowing the diagnosis and in comparison to the haemodynamic values (percentage of correct findings). The following procedure was adopted: In a control group of 143 healthy children, we first determined the vascular diameter of the right descending pulmonary artery, of the right upper lobal vein, and of the peripheral vessels in the upper and lower pulmonary fields, at an accurately defined distance from the point of the hilus, and compared with the vascular diameters of the children with left-right shunt, employing the method of discrimination analysis. Comparison of the judgement by the 4 investigators with the degree of increase of the vascular diameters showed an accuracy of 65-100% if the right descending pulmonary artery became wider by 2.6 mm, and an accuracy of 79-95% if the mean vascular width in the right upper field increased by 0.7 mm. The accuracy was 83-94% if the mean vascular width in the right lower field increased by 0.6 mm. Statistical studies also showed that the judgement of the 4 investigators was influenced by different vessels. (orig.) [de

    Aortico-left ventricular tunnel (ALVT) is a rare congenital cardiac defect that bypasses the aortic valve via a para-valvular connection from the left ventricle to the aorta. In most cases, the tunnel arises from the right aortic sinus. In this case report, we are presenting a case of ALVT, of which the aortic orifice arose from the left aortic sinus, requiring special attention to avoid the left coronary artery injury at the time of surgical repair.

    In political science the economic left-right dimension plays a central role. A growing body of evidence shows that the economic policy preferences of a large segment of citizens do not scale sufficiently. Using Mokken scale analysis, this study determines the causes of this phenomenon. Differences in the extent to which the economic policy preferences of citizens fit the left-right dimension can be explained in terms of the interaction between individual level and political system-level variables: citizens who spend more attention to politicians with views that conform to the left-right dimension, have views that conform to the left-right dimension. There is also a role for the legacy of communist dictatorship: citizens who were socialised in democratic countries have views that fit the left-right dimension better than those socialised during communism.

    The authors made comparative studies of CT findings with upper GI series and surgical findings in 20 cases of histologically proven gastric cancers. The identification of chickening of gastric wall and local and remote metastasis by CT was thought to be great value in treatment planning and prediction of prognosis of the patients. The results were as follows: 1. Of 20 cases, 19 cases demonstrated thickening of gastric wall. Among 3 cases suggested as early cancer on upper GI series, 2 cases demonstrated thickened gastric wall on CT and it was proved to be advanced cancer at surgery. 2. Out of 8 cases showed no definite metastasis on CT, 4 cases had malignant infiltration histologically in the regional lymph nodes. But they were less than 1.5 cm in diameter. 3. The frequency order of remote metastasis found by CT was pancreas, liver, left adrenal gland and lung in organs and retroperitoneal, retrocrural and regional nodes in lymph nodes.

    Atrial fibrillation transcatheter ablation (TCA) is, within available atrial fibrillation rhythm control strategies, one of the most effective. To potentially improve ablation outcome in case of recurrent atrial fibrillation after a first procedure or in presence of structural myocardial disease, isolation of the pulmonary veins may be associated with extensive lesions within the left atrium. To avoid rare, but potentially life-threatening, complications, thorough knowledge and assessment of left atrium anatomy and its relation to structures in close proximity are, therefore, mandatory. Aim of the present study is to describe, by cardiac computed tomography, the anatomic relationship between aortic root, left coronary artery and left atrium in patients undergoing atrial fibrillation TCA. The cardiac computed tomography scan of 21 patients affected by atrial fibrillation was elaborated to segment left atrium, aortic root and left coronary artery from the surrounding structures and the following distances measured: left atrium and aortic root; left atrium roof and aortic root; left main coronary artery and left atrium; circumflex artery and left atrium appendage; and circumflex artery and mitral valve annulus. Above all, the median distance between left atrium and aortic root (1.9, 1.5-2.1 mm), and between circumflex artery and left atrium appendage ostium (3.0, 2.1-3.4 mm) were minimal (≤3 mm). None of measured distances significantly varied between patients presenting paroxysmal versus persistent atrial fibrillation. The anatomic relationship between left atrium and coronary arteries is extremely relevant when performing atrial fibrillation TCA by extensive lesions. Therefore, at least in the latter case, preablation imaging should be recommended to avoid rare, but potentially life-threatening, complications with the aim of an as well tolerated as possible procedure.

    Human body models have the potential to better describe the human anatomy and variability than dummies. However, data sets available to verify the human response to impact are typically limited in numbers, and they are not size or gender specific. The objective of this study was to investigate the use of model morphing methodologies within that context. In this study, a simple human model scaling methodology was developed to morph two detailed human models (Global Human Body Model Consortium models 50th male, M50, and 5th female, F05) to the dimensions of post mortem human surrogates (PMHS) used in published literature. The methodology was then successfully applied to 52 PMHS tested in 14 impact conditions loading the abdomen. The corresponding 104 simulations were compared to the responses of the PMHS and to the responses of the baseline models without scaling (28 simulations). The responses were analysed using the CORA method and peak values. The results suggest that model scaling leads to an improvement of the predicted force and deflection but has more marginal effects on the predicted abdominal compressions. M50 and F05 models scaled to the same PMHS were also found to have similar external responses, but large differences were found between the two sets of models for the strain energy densities in the liver and the spleen for mid-abdomen impact simulations. These differences, which were attributed to the anatomical differences in the abdomen of the baseline models, highlight the importance of the selection of the impact condition for simulation studies, especially if the organ location is not known in the test. While the methodology could be further improved, it shows the feasibility of using model scaling methodologies to compare human models of different sizes and to evaluate scaling approaches within the context of human model validation.

    To evaluate the angiographic anatomy of the accessory left gastric artery (accLGA). We evaluated the angiographic findings of the accLGA in 50 patients (Angiostar; Siemens, Erlangen, Germany). Performing celiac and selective angiography in 50 and 34 patients, respectively. By means of celiac angiography, (1) site of origin, (2) anatomical course, (3) diameter, (4) degree of tortuosity, and (5) distal tapering were evaluated, while selective angiography was used to determine (1) arterial branching, (2) area of blood supply, and (3) patterns of gastric wall stain. Celiac angiography showed that the accLGA arose from the left hepatic artery (LHA) in 45 cases (90%) and from the proper hepatic artery in five (10%). If the accLGA arose from the LHA, its origin entirely depended on the branching pattern of the latter. It always arose from the lateral branch of the LHA furthest to the left and uppermost, and proximal to its umbilical point. The most common anatomical course of the accLGA, seen in 27 cases (54%), was between the S2 and S3 segmental branch. The diameter and degree of tortuosity of the accLGA were similar to those of adjacent intrahepatic branches in 21 (42%) and 33 cases (66%), respectively. The degree of tapering was less than that of adjacent intrahepatic vessel in 28 (56%). Selective angiography demonstrated esophageal branching of the acc LGA in 27 cases (79%), inferior phrenic arterial branching in three (9%), a mediastinal branch in one (3%), and hypervascularity of the lung in one (3%). In 15 cases (44%), bifurcation of the accLGA was recognized. The vascular territory of the accLGA was the gastric fundus together with the distal esophagus in 21 cases (62%), mainly the gastric fundus in six (18%), and mainly the distal esophagus in four (12%). The pattern of gastric mucosal stain was curvilinear wall in 31 cases (91%) and nodular in three (9%). A knowledge of the angiographic anatomy of the accLGA facilitates accurate recognition of this artery on

    Catheter ablation of atrial fibrillation has been associated with left-sided phrenic nerve palsy. Knowledge of the individual left phrenic nerve course therefore is essential to prevent nerve injury. The aim of this study was to test the feasibility of an intraprocedural pace mapping and reconstruction of the left phrenic nerve course and to characterize which anatomical areas are affected. In patients undergoing left atrial catheter ablation, a three-dimensional map of the left atrial anatomical structures was created. The left-sided phrenic nerve course was determined by high-output pace mapping and reconstructed in the map. In this study, 40 patients with atrial fibrillation or atrial tachycardias were included. Left phrenic nerve capture was observed in 23 (57.5%) patients. Phrenic nerve was captured in 22 (55%) patients inside the left atrial appendage, in 22 (55%) in distal parts, in 21 (53%) in medial parts, and in two (5%) in ostial parts of the appendage. In three (7.5%) patients, capture was found in the distal coronary sinus and in one (2.5%) patient in the left atrium near the left atrial appendage ostium. Ablation target was changed due to direct spatial relationship to the phrenic nerve in three (7.5%) patients. No phrenic nerve palsy was observed. Left-sided phrenic nerve capture was found inside and around the left atrial appendage in the majority of patients and additionally in the distal coronary sinus. Phrenic nerve mapping and reconstruction can easily be performed and should be considered prior catheter ablations in potential affected areas. ©2014 Wiley Periodicals, Inc.

    Bolus tracking can individualize time delay for the start of scans in spiral computed tomography (CT). We compared automatic bolus tracking method with fixed time-delay technique in biphasic contrast enhancement during multidetector CT of abdomen. Adult patients referred for spiral CT of the abdomen were randomized into two groups; in group 1, the arterial and portal phases of spiral scans were started 25 s and 55 s after the start of contrast material administration; in group 2, using the automatic bolus tracking software, repetitive monitoring scans were performed within the lumen of the descending aorta as the region of interest with the threshold of starting the diagnostic scans as 60 HU. The contrast enhancement of the aorta, liver, and spleen were compared between the groups. Forty-eight patients (23 males, 25 females, mean age=56.4±13.5 years) were included. The contrast enhancement of the aorta, liver, and spleen at the arterial phase was similar between the two groups (P>0.05). Regarding the portal phase, the aorta and spleen were more enhanced in the bolus-tracking group (P<0.001). The bolus tracking provided more homogeneous contrast enhancement among different patients than the fixed time-delay technique in the liver at portal phase, but not at the arterial phase. The automatic bolus-tracking method, results in higher contrast enhancement of the aorta and spleen at the portal phase, but has no effect on liver enhancement. However, bolus tracking is associated with reduced variability for liver enhancement among different patients

We describe an unusual case of a young boy presenting with persistent atrial tachycardia and congestive heart failure. He was detected to have unexplained grossly dilated right atrium, right ventricle with systolic dysfunction and a giant coronary sinus (CS. The dilated CS closely mimicked a pseudo cor-triatriatum on echocardiography. Contrast echocardiography from both arms revealed opacification of the CS before the right atrium. Bilateral upper limb venography confirmed the presence of absent right SVC and isolated persistent left SVC draining into the giant coronary sinus.

    Recent evidence shows that event-related (upper) alpha desynchronization (ERD) is related to cognitive performance. Several studies observed a positive, some a negative relationship. The latter finding, interpreted in terms of the neural efficiency hypothesis, suggests that good performance is associated with a more 'efficient', smaller extent of cortical activation. Other studies found that ERD increases with semantic processing demands and that this increase is larger for good performers. Studies supporting the neural efficiency hypothesis used tasks that do not specifically require semantic processing. Thus, we assume that the lack of semantic processing demands may at least in part be responsible for the reduced ERD. In the present study we measured ERD during a difficult verbal-semantic task. The findings demonstrate that during semantic processing, more intelligent (as compared to less intelligent) subjects exhibited a significantly larger upper alpha ERD over the left hemisphere. We conclude that more intelligent subjects exhibit a more extensive activation in a semantic processing system and suggest that divergent findings regarding the neural efficiency hypotheses are due to task specific differences in semantic processing demands.

    Full Text Available Splenosis can be considered as a benign condition due to the presence of heterotopic splenic tissue in abdomen, thorax and pelvis because of a massive splenic trauma or surgery. Here we report the case of a patient with an unknown hepatic mass, chronic hepatitis C, liver cirrhosis and a previous splenectomy after abdominal trauma. In our case lesion could not be clearly defined by ultrasound, computed tomography and magnetic resonance. Classical features of malignancy were not demonstrated at computed tomography, while at magnetic resonance imaging the differential diagnosis of the lesion appeared quite difficult and debate. Then an ultrasound-guided biopsy demonstrated the liver mass in left hepatic lobe consisted of splenic tissue and some millimetric accessory spleens in the left upper quadrant. So the possibility of an intra-hepatic splenosis should be taken into account in patients with an unknown liver mass and a history of previous abdominal trauma, followed by splenectomy. The conclusive diagnosis of intra-hepatic splenosis was given by ultrasound-guided biopsy.

    Percutaneous endovascular therapy is an accepted and preferred procedure for symptomatic subclavian artery disease. However, the technical feasibility and effectiveness of treating chronic total occlusion of the subclavian artery with this approach is uncertain. We aimed to evaluate the initial and mid-term results of endovascular therapy for patients with symptomatic chronic total occlusion of the left subclavian artery. Consecutive patients who underwent balloon angioplasty and stenting for chronic total occlusion of the left subclavian artery between January 2010 and February 2014 were included. Overall, 16 patients (10 male, 6 female; mean age 56 ± 13 years) underwent balloon angioplasty and stenting for chronic total occlusion of the left subclavian artery - 6 (37.5%) had arm claudication, 8 (50.0%) had vertebrobasilar insufficiency and 2 (12.5%) had coronary steal. 18 balloon-expandable stents were implanted to 15 patients. The central luminal passage was not achieved in one patient because of the subintimal position of guidewire (procedural success rate 93.8%). There were no procedure-related complications. Mean preprocedural and postprocedural systolic blood pressure differences between the upper extremities were 37 ± 13 (range 25-60) mmHg and 11 ± 9 (range 5-38) mmHg, respectively; the improvement was statistically significant. Outpatient follow-up revealed one asymptomatic restenosis at two years. Patency rate at two years was 93.3%. Balloon angioplasty and stenting for chronic total occlusion of the left subclavian artery is safe and effective, with good acute success rate and mid-term patency. Prospective randomised studies on larger patient populations would provide more precise results.

    Acute gastric volvulus is a rare, but potentially life-threatening, cause of upper gastrointestinal obstruction. Male of 60 years old with severe epigastric pain and abdominal distension with haematemesis on two occasions. The patient was haemodynamically stable, with abdominal distension and palpable epigastric fullness. Hematic cytology showed: haemoglobin 8.2g/dl and haematocrit 27%. Abdominal X-ray showed an elevation of left diaphragm with a hugely dilated stomach. A nasogastric tube was inserted. Endoscopy was performed. There was no active bleeding, but it was impossible to reach the duodenum due to the stomach distortion. The upper gastrointestinal X-ray study showed the appearance of an inverted stomach in the chest and an organoaxial gastric torsion. The CT scans of thorax and abdomen showed a gastric ascent into the thoracic cavity. Laparoscopic surgery was performed, finding the left hemi-diaphragm elevated, and the stomach, splenic angle of the colon, the spleen and tail of the pancreas were also raised. A linear gastrectomy (gastric sleeve) was performed. The postoperative progress was satisfactory. Oral feeding was started 72 hours after surgery, and the patient was discharged, and has remained asymptomatic during the following by 8 years. Emergency physicians must maintain a high level of suspicion in patients that present with signs and symptoms suggesting upper digestive tract occlusion. The gastric sleeve is an excellent alternative to avoid recurrence of gastric volvulus. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

    It is a popular concept in clinical neurology that muscles of the lower face receive predominantly crossed cortico-bulbar motor input, whereas muscles of the upper face receive additional ipsilateral, uncrossed input. To test this notion, we used focal transcranial magnetic brain stimulation to quantify crossed and uncrossed cortico-muscular projections to 6 different facial muscles (right and left Mm. frontalis, nasalis, and orbicularis oris) in 36 healthy right-handed volunteers (15 men, 21 women, mean age 25 years). Uncrossed input was present in 78% to 92% of the 6 examined muscles. The mean uncrossed: crossed response amplitude ratios were 0.74/0.65 in right/left frontalis, 0.73/0.59 in nasalis, and 0.54/0.71 in orbicularis oris; ANOVA p>0.05). Judged by the sizes of motor evoked potentials, the cortical representation of the 3 muscles was similar. The amount of uncrossed projections was different between men and women, since men had stronger left-to-left projections and women stronger right-to-right projections. We conclude that the amount of uncrossed pyramidal projections is not different for muscles of the upper from those of the lower face. The clinical observation that frontal muscles are often spared in central facial palsies must, therefore, be explained differently. Moreover, gender specific lateralization phenomena may not only be present for higher level behavioural functions, but may also affect simple systems on a lower level of motor hierarchy.

    The relation between neurological signs and symptoms and computed tomography (CT) and magnetic resonance imaging (MRI) was examined in 11 cases of occlusion of the left posterior cerebral artery. All the patients were righthanded. Right homonimous hemianopia was noted in 8 cases, right upper quadrantanopia in 2 cases, and right lower quadrantanopia in 1 case. Of the 11 cases, alexia without agraphia was noted in 9 cases, all 9 of which showed lesions of inferior occipital cortex (lingual and fusiform gyri) and subjacent white matter. Lesions of splenium were found in only 5 of the cases of alexia without agraphia. In 2 cases with neither alexia nor agraphia, lesions were seen in the medial occipital cortex and the subjacent white matter but not in the inferior occipital lobe. Three patients had color anomia which was accompanied by memory disturbances and alexia without agraphia. In 2 of these 3, lesions were widespread in the region of the left posterior cerebral artery. Memory disturbances were observed in 6 cases, all of which also showed alexia without agraphia. The lesions extended not only of the inferior surface of the occipital lobe and along the interhemispheric fissure, but also of hippocampal and parahippocampal gyri. In 3 cases of alexia without agraphia in which no memory distrubance was found, the symptoms of alexia were slight and disappeared at an early stage. (J.P.N.)

    Umbilical cord abnormalities are accepted as conditions associated with intrauterine fetal demise (IUFD), and umbilical cord stricture is most frequently encountered. In addition, although cord entanglement with multiple loops rarely increases the perinatal mortality, it is associated with a significant increase in variable kind of morbidity such as growth restriction. We describe a 27-year-old woman, with a missed abortion history at about 10 weeks' gestation in her first pregnancy, who presented to our outpatient department at 34 4/7 weeks of gestation due to decreased fetal activity during the preceding week. No fetal heart activity and blood flow had been detected by ultrasonography and pulsed-wave Doppler. A demised fetus with umbilical cord stricture and three loops around abdomen was delivered and was weighted 1,830 g that was below the tenth percentile for the gestational age. Either umbilical cord stricture or entanglement around the body can affect the development of the fetus and even be lethal. The former might play a more important role in this case. Their etiology and the sequence of the events are still undetermined, and additional evaluation such as autopsy and further research may be needed. In addition, counsel and frequent fetal surveillance should be done in patients with previous IUFD attributed to cord stricture during next pregnancy because of undetermined risk of recurrence.

    Full Text Available The main features of the Upper Devonian sediments on the right side of the Ostantsovy Creek (the left tributary of the Malaya Usa River in the eastern part of the Bielsko-Eletskaya structural formational belt on the western slope of the Polar Urals have been considered. The late Frasnian age of these sediments has been determined on the basis of conodonts (the linguiformis zone of the standard conodont scale. The transition from clastic and organic limestones with massive stromatoporoid forms to limestones with fused (reservoir stromatoporoid forms and Palmatolepis biofacies is indicative of the transgressive shift of the linguiformis phase. This transgressive level is an indirect expression of the Upper Kellwasser global event.

    Full Text Available Ureterosigmoidostomy is associated with the risk of several late complications including cancer development at anastomotic sites. We present an unusual case with adenocarcinoma of the anastomotic site associated with multiple adenocarcinoma lesions in the upper urinary tract. A 69-year-old man complained of persistent melena and hematuria. He had undergone radical cystectomy for high-grade bladder cancer and ureterosigmoidostomy 30 years before. Colonoscopy showed a tumor at the right ureterocolonic anastomosis, which was endoscopically resected and histologically diagnosed as adenocarcinoma. Seven years later, a tumor of the left ureterocolonic anastomosis associated with hydronephrosis was found. He underwent temporal percutaneous nephrostomy followed by sigmoidectomy and left ureterocutaneostomy. Eighteen months after the operation, computed tomography (CT detected left renal pelvic tumor with a mass along the former nephrostomy tract. Left nephroureterectomy and resection of the nephrostomy tract tumor revealed adenocarcinoma with multiple lesions of adenocarcinoma in the ureter. These tumors showed atypical immunohistochemistry as a colonic adenocarcinoma: positive for cytokeratin 7, negative for cytokeratin 20, and negative for β-catenin nuclear accumulation. Anastomotic site adenocarcinoma of the present case is potentially of urothelial origin because of unusual clinical manifestation and immunohistochemistry as a colon cancer.

    Improvements in technology and reduction in costs have led to widespread interest in three-dimensional (3D) printing. 3D-printed anatomical models contribute to personalized medicine, surgical planning, and education across medical specialties, and these models are rapidly changing the landscape of clinical practice. A physical object that can be held in one's hands allows for significant advantages over standard two-dimensional (2D) or even 3D computer-based virtual models. Radiologists have the potential to play a significant role as consultants and educators across all specialties by providing 3D-printed models that enhance clinical care. This article reviews the basics of 3D printing, including how models are created from imaging data, clinical applications of 3D printing within the abdomen and pelvis, implications for education and training, limitations, and future directions.

    Two different series collected at the University Hospital of Freiburg are presented as a basis for the critical appraisal of available imaging tests and their correlation with anatomic pain sites. The first series comprises 284 patients of non-traumatic acute abdomen admitted to the emergency department during 1990. The radiological approach revealed an increased use of immediate ultrasound (58%) followed by plain film radiography (53%), contrast studies (15%), and computed tomography (9.8%). Five groups of entities were identified according to the diagnostic imaging procedure prior to surgery. In a second series, the clinical presentation, the distribution and the efficacy of imaging studies for the confirmation of acute mesenteric ischemia were evaluated in 55 patients over a period of 14 years. A reduced mortality rate emphasizes the value of early and agressive diagnosis and angiographic management. (orig.)

    Complex regional pain syndrome (CRPS) is a major complication after trauma, surgery, and/or immobilization of an extremity. The disease often starts with clinical signs of local inflammation and develops into a prolonged phase that is characterized by trophic changes and local osteoporosis and sometimes results in functional impairment of the affected limb. While the pathophysiology of CRPS remains poorly understood, increased local bone resorption plays an undisputed pivotal role. The aim of this retrospective clinical study was to assess the bone microstructure in patients with CRPS. Patients with CRPS type I of the upper limb whose affected and unaffected distal radii were analyzed by high-resolution peripheral quantitative computed tomography (HR-pQCT) were identified retrospectively. The osteology laboratory data and dual-energy X-ray absorptiometry (DXA) images of the left femoral neck and lumbar spine, which were obtained on the same day as HR-pQCT, were extracted from the medical records. Five patients were identified. The CRPS-affected upper limbs had significantly lower trabecular numbers and higher trabecular thicknesses than the unaffected upper limbs. However, the trabecular bone volume to total bone volume and cortical thickness values of the affected and unaffected sides were similar. Trabecular thickness tended to increase with time since disease diagnosis. CRPS associated with significant alterations in the bone microstructure of the affected upper limb that may amplify as the duration of disease increases.

    Background. Tube current is an important determinant of radiation dose and image quality in X-ray-based examination. The combined automatic tube current modulation technique (ATCM) enables automatic adjustment of the tube current in various planes (x-y and z) based on the size and attenuation of the body area scanned. Purpose. To compare image quality and radiation dose of the ATCM with those of a fixed tube current technique (FTC) in CT of the abdomen and pelvis performed with a 16-slice multidetector row CT. Material and Methods. We reviewed 100 patients in whom initial and follow-up CT of the abdomen and pelvis were performed with FTC and ATCM. All acquisition parameters were identical in both techniques except for tube current. We recorded objective image noise in liver parenchyma, subjective image noise and diagnostic acceptability by using a five-point scale, radiation dose, and body mass index (BMI, kg/m2). Data were analyzed with parametric and non-parametric statistical tests. Results. There was no significant difference in image noise and diagnostic acceptability between two techniques. All subjects had acceptable subjective image noise in both techniques. The significant reduction in radiation dose (45.25% reduction) was noted with combined ATCM (P < 0.001). There was a significant linear statistical correlation between BMI and dose reduction (r = -0.78, P < 0.05). Conclusion. The ATCM for CT of the abdomen and pelvis substantially reduced radiation dose while maintaining diagnostic image quality. Patients with lower BMI showed more reduction in radiation dose
